[0029] The sorting equipment can be provided with a push plate assembly, which pushes or hits different materials through the push plate assembly, thereby achieving separation and sorting of the materials. Since the material sorting equipment is large in size, it can achieve the sorting of a large number of materials at the same time, and it is necessary to ensure the accuracy of material sorting. Therefore, it is necessary to set up multiple push plate assemblies according to the size of the materials and the size of the sorting equipment, so that materials located at different positions can be sorted, and the size of the push plate can be matched with the size of the materials, thereby effectively avoiding missorting or missed sorting. The push plate assembly needs to be inspected for its model, specifications and quality to ensure that the push plate assembly is qualified and can be sorted normally, avoiding incorrect sorting or material waste caused by uneven push plate surface or large push plate size error. In addition, during the process of installing the push plate assembly on the sorting equipment, if the push plate assembly is unqualified, it may cause interference between multiple push plate assemblies, affecting the sorting accuracy of the material sorting equipment. Specifically, in some current technologies, the push plate assembly is assembled, and the push plate, rotating shaft and other structures of the push plate assembly can be produced separately, and then combined into a push plate assembly. For the assembled push plate assembly, in the process of inspecting whether it is qualified, each independent structure can be inspected separately, and the inspection process is relatively simple. However, the production process of the assembled push plate assembly is relatively complicated, the production cost is high, and the strength of the push plate assembly is low, which makes it difficult to adapt to the sorting of materials with larger size or heavier weight, and its push plate is prone to fatigue fracture. In other technologies, the push plate assembly can be manufactured in one piece by casting or other methods. It has high strength and can be applied to a variety of different material sorting situations. It can also achieve efficient and stable sorting for materials with larger size or heavier weight. In addition, the production process of the push plate assembly formed by casting is simple and the production cost is low. However, the push plate assembly formed in one piece by casting is prone to some errors in the manufacturing process, resulting in poor structural accuracy of the produced push plate assembly, and prone to unqualified situations such as uneven push plates and stuck rotating shafts. Therefore, it is necessary to inspect the push plate assemblies formed by casting to ensure that the push plate assemblies installed in the sorting equipment can operate normally and efficiently. Therefore, it is necessary to conduct batch inspections on the push plate assemblies of the material sorting equipment to ensure that the push plate assemblies installed in the sorting equipment are all qualified push plate assemblies, which can further ensure the sorting accuracy and efficiency of the material sorting equipment. However, it is currently difficult to implement batch inspections of push plate assemblies. Inspections of push plate assemblies are time-consuming and inefficient, and the inspections require a lot of manpower and are expensive.

[0030] like Figure 1 、 Figure 2As shown, an exemplary embodiment of the present disclosure provides an inspection tool for inspecting a push plate assembly 300 of a sorting device. The push plate assembly 300 may include a push plate and a pin 320 disposed at one end of the push plate 310. The inspection tool may include a first inspection fixture 110 and a second inspection fixture 120. The inspection tool provided by the present disclosure allows the push plate assembly 300 to be installed between the first inspection fixture 110 and the second inspection fixture 120. Through the cooperative relationship between the first inspection fixture 110, the second inspection fixture 120, and the push plate assembly 300, inspection of the push plate assembly 300 can be quickly and conveniently performed.

[0031] The first inspection tool 110, such as Figure 2 、 Figure 3 As shown, it can include two parallel first side plates 111, and each first side plate 111 has a first arc-shaped groove 1111 formed at the bottom. The first inspection fixture 110 can be provided with two first side plates 111, and the first side plates 111 can be provided in parallel with each other. The first side plates 111 can be connected by a plate so that the two first side plates 111 can remain parallel to each other. The bottom of the first side plate 111 can be formed with a first arc-shaped groove 1111, and the first arc-shaped groove 1111 can be provided at the center of the bottom of the first side plate 111. The first arc-shaped groove 1111 can be used to abut against the outer peripheral side of the pin shaft 320 of the push plate assembly 300, so that the first inspection fixture 110 can be installed on the push plate assembly 300 during the inspection process.

[0032] The second inspection tool 120, such as Figure 2 、 Figure 4 As shown, it may include a bottom plate 121 and two second side plates 122 .

[0033] Bottom plate 121, such as Figure 7 As shown, the upper surface is used to abut against the push plate 310 and is used to detect the flatness of the push plate 310. The bottom plate 121 can abut against the push plate 310 so that the upper surface of the bottom plate 121 abuts against the striking surface of the push plate 310 used to strike the material. The flatness of the push plate 310 can be determined based on the contact state between the upper surface of the bottom plate 121 and the striking surface of the push plate 310. When the upper surface of the bottom plate 121 abuts against the striking surface of the push plate 310 without a gap, it can be determined that the flatness of the push plate 310 is qualified. If there is a gap between the upper surface of the bottom plate 121 and the striking surface of the push plate 310, the flatness of the push plate 310 is unqualified. The bottom plate 121 provided in this embodiment can more simply and intuitively determine the flatness of the push plate 310.

[0034] Two second side panels 122, such as Figure 2 、 Figure 5 As shown, the upper surface of each second side plate 122 is formed with a second arc groove 1221 that matches the first arc groove 1111, and the upper surface of each second side plate 122 is parallel to the upper side of the bottom plate 121. Figure 7 As shown, the first arcuate groove 1111 and the second arcuate groove 1221 form an axial hole 130 for accommodating the pin shaft 320 to detect the coaxiality of the pin shaft 320. The second inspection fixture 120 may include two second side plates 122. The two second side plates 122 may be arranged parallel to each other, and the two second side plates 122 may be respectively arranged corresponding to the first side plate 111, so that the second side plates 122 and the first side plates 111 are arranged in a one-to-one correspondence. The two second side plates 122 may be arranged at the same end of the upper side surface of the bottom plate 121 and located on opposite sides of the bottom plate 121, so that the second side plates 122 and the first side plates 111 are arranged in a one-to-one correspondence.

[0035] like Figure 2 As shown, a second arcuate groove 1221 can be formed on the upper surface of each second side plate 122. The second arcuate groove 1221 can be used to abut the outer circumference of the pin 320, so that the push plate assembly 300 can be installed on the second inspection fixture 120 during the inspection process. The dimensions of the first arcuate groove 1111 formed at the bottom of the first side plate 111 and the second arcuate groove 1221 formed at the top of the second side plate 122 can match each other, and the opening positions of the first arcuate groove 1111 and the second arcuate groove 1221 can correspond to each other, so that the first arcuate groove 1111 and the second arcuate groove 1221 can cooperate to form the shaft hole 130 for accommodating the pin 320. The coaxiality of the pin 320 can be determined by the cooperation between the outer circumference of the pin 320 and the shaft hole 130. Because two pins 320 are located at the same end of the push plate 310, protruding from either side of the rotating shaft 330 of the push plate 310 and arranged perpendicular to the extension direction of the push plate 310, the push plate 310 can rotate along the centerline of the pins 320 to strike the material. If the coaxiality of the pins 320 meets the requirements of the push plate assembly 300, the push plate 310 can rotate along the centerline of the pins 320, thereby smoothly striking the material and achieving material sorting. If the coaxiality of the pins 320 does not meet the requirements of the push plate assembly 300, the push plate 310 is likely to get stuck during rotation along the centerline of the pins 320, causing the push plate assembly 300 to malfunction and affect the accuracy of material sorting. Therefore, the push plate assembly 300 can be installed between the first and second inspection fixtures 110 and 120 via the axial holes 130 formed between the first side plate 111 and the second side plate 122, with the pins 320 on either side of the push plate 310 respectively installed in the two axial holes 130. If the pins 320 interfere with the axial holes 130, it can be determined that the coaxiality of the pins 320 does not meet the requirements, and the push plate assembly 300 can be determined to be unqualified. If the pins 320 can be installed in the axial holes 130 without interference, it can be determined that the coaxiality of the pins 320 meets the requirements and the coaxiality of the pins 320 of the push plate assembly 300 is qualified.

[0036] The second inspection fixture 120 can be set on any plane, so that the lower surface of the base plate 121 of the second inspection fixture 120 abuts the plane, achieving stable installation. The push plate assembly 300 can be set on the base plate 121, so that the striking surface of the push plate 310 abuts the upper surface of the base plate 121. The second inspection fixture 120 can be set on any plane, so that the push plate 310 can be quickly placed on or removed from the second inspection fixture 120, thereby effectively saving inspection time. In addition, the inspection tool can be inspected using automated equipment. The second inspection fixture 120 can be fixed on any plane, such as by fixing the second inspection fixture 120 to a bracket. Automated equipment, such as a robotic arm, can be used to grab the push plate assembly 300 to be inspected and place it on the second inspection fixture 120, so that the striking surface of the push plate 310 abuts the upper surface of the base plate 121 of the second inspection fixture 120, and the pin 320 of the push plate assembly 300 is installed in the second arc-shaped groove 1221. Subsequently, the first inspection fixture 110 can be installed on the second inspection fixture 120 using automated equipment, so that the first arcuate groove 1111 of the first inspection fixture 110 and the second arcuate groove 1221 cooperate to form the axial hole 130. The pin 320 of the push plate assembly 300 can be accommodated in the axial hole 130, so that the push plate 310 is positioned between the first inspection fixture 110 and the second inspection fixture 120. An image acquisition device can be used to capture images of the inspection fixture at different angles. These images can be analyzed through image processing, manual observation, or deep learning models to determine whether the various parts of the push plate assembly 300 are properly aligned with the first inspection fixture 110 and the second inspection fixture 120. Specifically, the parallelism of the striking surface of the push plate 310 of the push plate assembly 300 can be determined by observing the contact between the striking surface of the push plate 310 and the bottom plate 121 of the second inspection fixture 120. The coaxiality of the pin 320 can be determined by observing the fit between the pin 320 at the end of the push plate assembly 300 and the axial hole 130. By determining the parallelism of the push plate 310 and the coaxiality of the pin 320 of the push plate assembly 300 in the above manner, it is possible to further determine whether the push plate assembly 300 is qualified.

[0037] According to the inspection fixture provided in this embodiment, through the matching structure of the first inspection fixture 110 and the second inspection fixture 120, the inspection fixture can complete the inspection of the push plate assembly 300 in a short time, avoiding the low efficiency problem caused by relying on traditional manual inspection methods. It is possible to achieve rapid batch inspection of multiple push plate assemblies 300, significantly improving the inspection efficiency. Through the inspection fixture provided in this embodiment, it is possible to effectively reduce labor costs and inspection time while ensuring that all push plate assemblies 300 of the sorting equipment are inspected, thereby improving the efficiency of the inspection of the push plate assembly 300. Through the contact between the bottom plate 121 and the striking surface of the push plate 310, it is possible to intuitively judge whether the flatness of the push plate 310 is qualified, avoiding problems such as offset and unstable striking caused by the uneven surface of the push plate 310. The shaft hole 130 formed by the first arc-shaped groove 1111 and the second arc-shaped groove 1221 can accurately test the coaxiality of the pin 320, which can effectively avoid the problem of the push plate 310 moving stuck or rotating unsmoothly due to the eccentricity or tilt of the pin 320. Therefore, it is possible to more accurately detect whether the push plate assembly 300 is qualified, so as to improve the smoothness and reliability of the movement of the push plate assembly 300 in actual sorting, ensure that the push plate 310 accurately hits the material, and avoid missed or wrong sorting. For the push plate assembly 300 of the material sorting equipment, the inspection tool provided by this embodiment can also realize the automatic placement, automatic alignment and automatic identification and analysis of the push plate assembly 300 based on automated equipment. It can combine image acquisition and deep learning models to intelligently identify and judge multiple parameters such as the flatness of the push plate 310 and the coaxiality of the pin 320, greatly reducing manual detection errors and subjective judgment differences. The inspection tool provided in this embodiment provides high repeatability and consistency for testing push plate assemblies 300, making it suitable for quality inspection of large quantities of push plate assemblies 300, effectively improving the accuracy and efficiency of quality inspection of push plate assemblies 300. Compared to traditional methods that rely on manual measurement and subjective judgment, the inspection tool provided in this embodiment is simple in structure and easy to manufacture, effectively reducing costs while improving inspection accuracy and efficiency.

[0038] In some embodiments, as Figure 1 、 Figure 2 As shown, Figure 1 The push plate assembly 300 may further include a rotating shaft 330, the axis of the rotating shaft 330 protruding to both sides to form a pin 320, wherein, as Figure 2 As shown, the two first side plates 111 are formed with a first accommodating space 1112 for accommodating at least the upper part of the rotating shaft 330 to detect the parallelism of both sides of the rotating shaft 330; and / or, the two second side plates 122 are formed with a second accommodating space 1222 for accommodating at least the lower part of the rotating shaft 330 to detect the parallelism of both sides of the rotating shaft 330.

[0039] like Figure 2As shown, a first accommodating space 1112 may be formed between the two first side panels 111, and the first accommodating space 1112 may be used to accommodate at least the upper portion of the rotating shaft 330. The two side walls of the two first side panels 111 that are arranged opposite each other may be the inner side walls of the first side panels 111, and a first accommodating space 1112 may be formed between the inner side walls of the first side panels 111. The two side walls of the rotating shaft 330 may respectively abut against the inner side walls of the two first side panels 111. Since a first arc-shaped groove 1111 is formed at the bottom of the first side panel 111, which is used to abut against the circumferential side of the pin 320 protruding from the axis of the rotating shaft 330, the inner side wall of the first side panel 111 of the inspection tool can at least partially abut against the rotating shaft 330. Because the two first side plates 111 are parallel to each other, the inner sidewalls of the two first side plates 111 that abut the sidewalls of the rotating shaft 330 are parallel to each other. The parallelism of the two sides of the rotating shaft 330 can be determined based on the abutment between the inner sidewalls of the first side plates 111 and the sidewalls of the rotating shaft 330. When the inner sidewalls of the first side plates 111 abut the sidewalls of the rotating shaft 330 without a gap, it can be determined that the parallelism of the two sides of the rotating shaft 330 meets the requirements. When there is a gap between the inner sidewalls of the first side plates 111 and the sidewalls of the rotating shaft 330, it can be determined that the parallelism of the two sides of the rotating shaft 330 does not meet the requirements.

[0040] like Figure 2 As shown, a second accommodating space 1222 can be formed between the two second side panels 122, and the second accommodating space 1222 can be used to accommodate at least the lower portion of the rotating shaft 330. The two side walls of the two second side panels 122 arranged opposite each other can be the inner side walls of the second side panels 122, and the second accommodating space 1222 can be formed between the inner side walls of the second side panels 122. The two side walls of the rotating shaft 330 can respectively abut against the inner side walls of the two second side panels 122. Because a second arc-shaped groove 1221 is formed on the top of the second side panel 122, which is used to abut against the circumference of the pin 320 protruding from the axis of the rotating shaft 330, the inner side walls of the second side panels 122 of the inspection tool can at least partially abut against the rotating shaft 330. Because the two second side plates 122 are parallel to each other, the inner sidewalls of the two second side plates 122 that abut the sidewalls of the rotating shaft 330 are parallel to each other. The parallelism of the two sides of the rotating shaft 330 can be determined based on the abutment between the inner sidewalls of the second side plates 122 and the sidewalls of the rotating shaft 330. When the inner sidewalls of the second side plates 122 abut the sidewalls of the rotating shaft 330 without a gap, it can be determined that the parallelism of the two sides of the rotating shaft 330 meets the requirements. When there is a gap between the inner sidewalls of the second side plates 122 and the sidewalls of the rotating shaft 330, it can be determined that the parallelism of the two sides of the rotating shaft 330 does not meet the requirements.

[0041] like Figure 2As shown, since the axis of the rotating shaft 330 of the push plate assembly 300 can protrude to both sides to form two pins 320, during the process of inspecting the push plate assembly 300 using the inspection tool, the pins 320 can be installed through the shaft hole 130 formed by the first arcuate groove 1111 and the second arcuate groove 1221, thereby testing the coaxiality of the pins 320. In addition, since the first side plates 111 and the second side plates 122 are arranged correspondingly, the distance between the two first side plates 111 is equal to the distance between the two second side plates 122, and the first accommodating space 1112 formed between the two first side plates 111 can be used to accommodate at least the upper portion of the rotating shaft 330, and the second accommodating space 1222 formed between the two second side plates 122 can be used to accommodate at least the lower portion of the rotating shaft 330. Therefore, the parallelism of the two sides of the rotating shaft 330 can be determined by the abutment between the inner side walls of the two first side panels 111 and the side walls of the rotating shaft 330, and the parallelism of the two sides of the rotating shaft 330 can also be determined by the abutment between the inner side walls of the two second side panels 122 and the side walls of the rotating shaft 330. In addition, since the first side panels 111 and the second side panels 122 are arranged correspondingly, the spacing between the two first side panels 111 is equal to the spacing between the two second side panels 122, and the first accommodating space 1112 and the second accommodating space 1222 are equal in size. Therefore, after the inspection tool is installed, the bottom of the first side panel 111 and the top of the second side panel 122 on the same side can be abutted to form a complete side panel. The parallelism of the two sides of the rotating shaft 330 can be tested by the abutment between the two side panels and the two sides of the rotating shaft 330.

[0042] According to the inspection tool provided in this embodiment, the parallelism of the two sides of the rotating shaft 330 in the push plate assembly 300 can be accurately inspected through the first accommodating space 1112 formed between the two first side plates 111 and the second accommodating space 1222 formed between the two second side plates 122. The first accommodating space 1112 and the second accommodating space 1222 can respectively accommodate the upper and lower portions of the rotating shaft 330, so that the inner side walls of the first side plates 111 and the second side plates 122 respectively contact the two side walls of the rotating shaft 330. By observing whether there is a gap between the inner side walls of the first side plates 111 and the second side plates 122 and the two side walls of the rotating shaft 330, the parallelism of the two sides of the rotating shaft 330 and the size of the rotating shaft 330 can be more intuitively determined. The first side plate 111 and the second side plate 122 are arranged in a one-to-one correspondence and remain parallel to each other. After the first inspection fixture 110 and the second inspection fixture 120 are installed in conjunction with each other, the first side plate 111 and the second side plate 122 located on the same side are abutted to form a complete side plate structure. By observing whether there is a gap between the inner side wall of the side plate as a whole and the two side walls of the rotating shaft 330, the parallelism of the two sides of the rotating shaft 330 and the size of the rotating shaft 330 can be further simply and intuitively judged. During the inspection process, there is no need to repeatedly disassemble or adjust the position of the inspection tooling, and the parallelism inspection of the upper and lower sides of the rotating shaft 330 can be completed at one time, which effectively improves the inspection efficiency, reduces the difficulty of inspection, and has higher inspection accuracy.

[0043] In some embodiments, as Figure 4 、 Figure 6 As shown, a rectangular groove 1211 is formed on the upper surface of the bottom plate 121. The bottom surface of the groove 1211 is used to abut the striking surface of the push plate 310 to detect the flatness of the striking surface. In addition, the side walls of the groove 1211 are used to abut at least part of the side surface of the push plate 310 to detect the size of the striking surface and the parallelism of the opposite side surfaces of the push plate 310. Since the push plate 310 is generally rectangular, the dimensions of the push plates 310 of the multiple push plate assemblies 300 in the sorting equipment are equal, which facilitates the installation of the push plate assemblies 300 and the control of the push plate assemblies 300 to perform sorting operations. Therefore, the shape and size of the push plate 310 of the push plate assembly 300 can be used as a necessary inspection parameter to ensure the uniformity of the specifications of the push plate assemblies 300. A rectangular groove 1211 can be formed on the upper surface of the bottom plate 121. The bottom surface of the groove 1211 can abut against the striking surface of the push plate 310, thereby determining whether the flatness of the striking surface is acceptable based on the state of abutment between the bottom surface of the groove 1211 and the striking surface of the push plate 310. When the bottom surface of the groove 1211 abuts against the striking surface of the push plate 310 without a gap, it can be determined that the flatness of the striking surface of the push plate 310 is acceptable. When the bottom surface of the groove 1211 abuts against the striking surface of the push plate 310 with a certain gap, it can be determined that the striking surface of the push plate 310 is unacceptable.

[0044] The sidewalls of the groove 1211 can abut at least a portion of the side surface of the push plate 310, thereby determining whether the parallelism of the two opposite sides of the push plate 310 is qualified based on the abutment between the sidewalls of the groove 1211 and the side surface of the push plate 310. When the sidewalls of the groove 1211 abut the side surface of the push plate 310 without a gap, the parallelism of the two opposite sides of the push plate 310 can be determined to be qualified. When the sidewalls of the groove 1211 abut the side surface of the push plate 310 with a certain gap, the parallelism of the two opposite sides of the push plate 310 can be determined to be unqualified. The two sidewalls of the groove 1211 along the width direction of the base plate 121 can respectively abut the two opposite sidewalls of the push plate 310 in the width direction. Therefore, the parallelism of the two opposite sidewalls of the push plate 310 in the width direction of the push plate 310 can be determined based on the abutment between the two sidewalls of the groove 1211 along the width direction of the base plate 121 and the two opposite sidewalls of the push plate 310 in the width direction. If the push plate 310 can be installed in the groove 1211 so that the two side walls of the groove 1211 along the width direction of the bottom plate 121 can abut against the two side walls of the push plate 310 that are opposite in the width direction, the width dimension of the push plate 310 can be determined to be acceptable. If the push plate 310 cannot be installed in the groove 1211, the width of the push plate 310 is greater than the width of the groove 1211, or the two side walls of the groove 1211 along the width direction of the bottom plate 121 cannot abut against the two side walls of the push plate 310 that are opposite in the width direction, the width dimension of the push plate 310 can be determined to be unacceptable. When there is no gap between the two side walls of the groove 1211 along the width direction of the base plate 121 and the two side walls opposite to each other in the width direction of the push plate 310, it can be determined that the parallelism of the two side walls opposite to each other in the width direction of the push plate 310 is qualified. When there is a gap between the two side walls of the groove 1211 along the width direction of the base plate 121 and the two side walls opposite to each other in the width direction of the push plate 310, it can be determined that the parallelism of the two side walls opposite to each other in the width direction of the push plate 310 is unqualified.

[0045] like Figure 8As shown, the two side walls of the groove 1211 along the length of the base plate 121 can respectively abut the two opposing side walls of the push plate 310 in the length direction. Therefore, the parallelism of the two opposing side walls of the push plate 310 in the length direction of the groove 1211 can be determined based on the abutment between the two side walls of the groove 1211 along the length of the base plate 121 and the two opposing side walls of the push plate 310 in the length direction. When the push plate 310 can be installed in the groove 1211, and the two side walls of the groove 1211 along the length of the base plate 121 abut against the two opposing side walls of the push plate 310 in the length direction of the push plate 310, the length dimension of the push plate 310 can be determined to be acceptable. When the push plate 310 cannot be installed in the groove 1211, the length of the push plate 310 is greater than the length of the groove 1211, or the two side walls of the groove 1211 along the length of the base plate 121 do not abut against the two opposing side walls of the push plate 310 in the length direction of the push plate 310, the length dimension of the push plate 310 can be determined to be unacceptable. When there is no gap between the two side walls of the groove 1211 along the length direction of the bottom plate 121 and the two side walls opposite to the push plate 310 in the length direction, it can be determined that the parallelism of the two side walls opposite to the push plate 310 in the length direction is qualified. When there is a gap between the two side walls of the groove 1211 along the length direction of the bottom plate 121 and the two side walls opposite to the push plate 310 in the width direction, it can be determined that the parallelism of the two side walls opposite to the push plate 310 in the length direction is unqualified. Figure 8 As shown, the groove 1211 can also be connected to the end side wall of the bottom plate 121 in its length direction along the length direction of the bottom plate 121, that is, the length extension direction of the push plate 310, so that the inspection tool only inspects the parallelism and size of the two side walls relative to each other in the width direction of the push plate 310, without inspecting the parallelism and size of the two side walls relative to each other in the length direction of the push plate 310, thereby adapting to push plates 310 of various different lengths and having a wider range of applications.

[0046] According to the inspection fixture provided in this embodiment, by providing a rectangular groove 1211 structure on the upper surface of the bottom plate 121 of the inspection fixture, the flatness of the striking surface, the parallelism of the side walls, and the length and width dimensions of the push plate 310 can be quickly tested. The bottom surface of the groove 1211 is used to directly abut the striking surface of the push plate 310. When the striking surface flatness is qualified, it fits tightly with the bottom surface of the groove 1211 without any visible gap, making it possible to quickly and easily determine the flatness of the striking surface, avoiding the use of complex measuring instruments to test flatness, improving testing efficiency while reducing the cost of testing equipment. The two opposite side walls of the groove 1211 in the width direction and the two opposite side walls of the groove 1211 in the length direction can respectively abut the corresponding side walls of the push plate 310. When the opposite side walls of the push plate 310 are parallel and of qualified size, they fit seamlessly with the side walls of the groove 1211. This allows the width and length dimensions of the push plate 310, as well as the parallelism of the opposite side walls, to be quickly and easily determined, achieving high testing efficiency. Furthermore, the inspection fixture provided in this embodiment enables efficient inspection of the push plate assembly 300, particularly when batch inspection of push plates 310 of the same specification is required. This effectively ensures the consistency of the push plate assembly 300 throughout the entire device, further improving the inspection efficiency and accuracy of the push plate assembly 300. In some cases, the groove 1211 is connected to the end of the base plate 121 at one end in the longitudinal direction. In this case, the inspection fixture does not forcibly constrain the length of the push plate 310, making it suitable for a series of push plates 310 that require a uniform width but allow for length variations. This allows for uniform inspection of the width and parallelism of push plates 310 of different lengths, improving the adaptability and versatility of the inspection device and facilitating the inspection of multiple models and batches of products.

[0047] In some embodiments, the distance between the two first side panels 111 is greater than or equal to 50 mm and less than or equal to 62 mm; and / or the length of the groove 1211 is greater than or equal to 180 mm and less than or equal to 250 mm; and / or the width of the groove 1211 is greater than or equal to 70 mm and less than or equal to 80 mm.

[0048] A first accommodating space 1112 may be formed between the two first side plates 111 for accommodating the rotating shaft 330 and detecting the size of the rotating shaft 330 in the width direction of the push plate assembly 300. The width of the push plate 310 may be limited by limiting the distance between the first side plates 111. The push plate assembly 300 detected by the inspection tool disclosed in the present invention can be mainly used for sorting ore. The distance between the two first side plates 111 may be greater than or equal to 50 mm, and less than or equal to 62 mm. If the distance between the two first side plates 111 is less than 50 mm, the push plate 310 is too small to achieve sorting of ore materials. If the distance between the two first side plates 111 is greater than 62 mm, the push plate 310 is too large to achieve high-precision sorting. Specifically, Figure 8 As shown, according to the A-direction cross-sectional inspection diagram of the inspection tool, the distance between the two first side plates 111 can be 56mm, and the tolerance can be -0.45mm to -0.4mm. When there is a certain gap between the rotating shaft 330 of the push plate assembly 300 and the inner side walls of the two first side plates 111, so that the rotating shaft 330 can rotate freely, it can be determined that the parallelism of the rotating shaft 330 is qualified.

[0049] The groove 1211 can be used to accommodate the push plate 310, so that the bottom surface of the groove 1211 abuts against the striking surface of the push plate 310 to determine the flatness of the striking surface of the push plate 310. The push plate 310 is installed in the groove 1211, and the width dimension and parallelism of the push plate 310 can be determined by the relationship between the two side walls in the width direction of the groove 1211 and the corresponding side walls of the push plate 310. The length dimension and parallelism of the push plate 310 can be determined by the relationship between the two side walls in the length direction of the groove 1211 and the corresponding side walls of the push plate 310. The width of the groove 1211 is greater than or equal to 70 mm and less than or equal to 80 mm. Specifically, as Figure 8 As shown, according to the A-direction cross-sectional inspection diagram of the inspection fixture, it can be determined that the width of the groove 1211 can be 75mm, and its tolerance can be 0~0.05mm. When the two side walls opposite to each other in the width direction of the push plate 310 abut against the two side walls in the width direction of the groove 1211 or there is a small gap, it can be determined that the width dimension of the groove 1211 is qualified. The length of the groove 1211 can be greater than or equal to 180mm and less than or equal to 250mm. Specifically, the length of the groove 1211 can be 229mm, and its tolerance can be 0~0.05mm. When the two side walls opposite to each other in the length direction of the push plate 310 abut against the two side walls in the length direction of the groove 1211 or there is a small gap, it can be determined that the length dimension of the groove 1211 is qualified.

[0050] In addition, the diameter of the shaft hole 130 for checking the coaxiality of the pin shaft 320 formed by the first arc groove 1111 of the first side plate 111 and the second arc groove 1221 of the second side plate 122 can be greater than or equal to 15 mm and less than or equal to 23 mm. Figure 7 As shown, according to the left view inspection diagram of the inspection tool, it can be determined that the diameter of the shaft hole 130 can be 19mm with a tolerance of -0.15mm to -0.1mm. When the pin 320 of the push plate assembly 300 can rotate freely in the shaft hole 130, it can be determined that the coaxiality of the pin 320 of the push plate 310 is qualified.

[0051] According to the inspection fixture provided in this embodiment, by limiting the distance between the first side plates 111, the size of the rotating shaft 330 of the push plate 310 that it detects can be effectively limited, and by limiting the length and width of the groove 1211, the length and width of the push plate 310 that it detects can be effectively limited. According to the inspection fixture provided in this embodiment, by setting and controlling the dimensions and tolerances of multiple key parts of the inspection fixture, such as the first side plates 111 and the grooves 1211, it is possible to accurately inspect the size, flatness, parallelism, and coaxiality of various structural components such as the rotating shaft 330 and the push plate 310 of the push plate assembly 300. The inspection fixture provided in this embodiment has a reasonable structural design and simple inspection operation. It is highly adaptable to the factory inspection and assembly calibration scenarios of the push plate assembly 300 of ore and other material sorting equipment, greatly improving the inspection efficiency and accuracy of the push plate assembly 300.

[0052] In some embodiments, at least one sidewall of the groove 1211 is formed with a notch 1212 that communicates with the side surface of the bottom plate 121, such that the side surface of the push plate 310 disposed in the groove 1211 is exposed through the notch 1212. At least one sidewall of the groove 1211 can communicate with the side surface of the bottom plate 121, forming the notch 1212. A user can determine the contact state between the striking surface of the push plate 310 and the bottom surface of the groove 1211 through manual observation or image acquisition and analysis on the side where the notch 1212 is located. When the bottom surface of the groove 1211 abuts the striking surface of the push plate 310 without a gap, the flatness of the striking surface of the push plate 310 can be determined to be acceptable. When the bottom surface of the groove 1211 abuts the striking surface of the push plate 310 but with a gap, the flatness of the striking surface of the push plate 310 can be determined to be unacceptable. The length of the notch 1212 can be smaller than the length of the groove 1211, so that the user can observe the state of the bottom surface of the groove 1211 abutting the striking surface of the push plate 310 through one side of the notch 1212, while also ensuring that the push plate 310 is restricted by the side wall of the groove 1211, thereby preventing the push plate 310 from slipping out of the groove 1211 and affecting the efficiency of inspection and detection.

[0053] According to the inspection tool provided in this embodiment, the notch 1212 provided on the side wall of the groove 1211 provides a visual channel for the inspection personnel or image acquisition device performing the inspection of the push plate 310, so that the inspection personnel can directly observe whether there is a gap between the striking surface of the push plate 310 and the bottom surface of the groove 1211 from the outside of the groove 1211. By making the length of the notch 1212 less than the overall length of the groove 1211, the constraint of the groove 1211 on the push plate 310 is ensured, effectively preventing the push plate 310 from slipping or tilting from the groove 1211 due to the opening of the notch 1212, ensuring the stability and safety of the inspection process, and improving the inspection efficiency. Through the inspection tool provided in this embodiment, it is possible to quickly determine whether the flatness of the striking surface of the push plate 310 meets the standard without the user touching the push plate 310 components, realizing intuitive and visual inspection of the flatness of the striking surface, and effectively improving the ease of use and inspection efficiency of the inspection tool.

[0054] In some embodiments, as Figure 3 、 Figure 9 As shown, the push plate assembly 300 may also include two parallel ribs 340 arranged on the back side of the push plate 310. Since the striking surface of the push plate 310 needs to hit the material, the push plate 310 is subjected to a large impact during the material sorting process and is prone to fatigue or fracture. Therefore, a rib 340 for supporting the push plate 310 can be provided on the back side of the striking surface, thereby improving the strength of the push plate 310 and preventing the push plate 310 from fatigue or fracture due to the impact of the material during the material sorting process. The rib 340 can be in a relatively stable shape such as a trapezoid or a triangle. Two ribs 340 can be provided, and they can be provided at both ends of the push plate 310 along the width direction, so as to achieve better support and reinforcement effects. The first inspection fixture 110 may also include: a top plate 112 and an extension plate 113.

[0055] The top plate 112 is connected to the top of at least one first side plate 111. The top plate 112 can be at least partially disposed between the two opposite first side plates 111, and the top plate 112 can be connected to the top of at least one first side plate 111, thereby maintaining relative stability with the first side plate 111. The top plate 112 can also be as Figure 4 As shown, the top plate 112 is disposed between the two first side plates 111, with both ends of the top plate 112 along the width direction being fixedly connected to the two first side plates 111, thereby forming a shell-like shape when combined with the first side plates 111 and the top plate 112. The top plate 112 can be connected to the top of at least one of the first side plates 111, and the height of the first side plate 111 is greater than or equal to half the radius of the rotation axis 330. When the first inspection fixture 110 is placed over the second inspection fixture 120 on which the push plate assembly 300 to be tested is installed, the top plate 112 can effectively limit the position of the rotation axis 330 of the push plate assembly 300, preventing the push plate assembly 300 from slipping or falling during the inspection process.

[0056] The extension plate 113 is connected to the top plate 112 at one end and extends away from the first side plate 111 at the other end. It is located above the bottom plate 121 and is used to extend between the two ribs 340 to detect the parallelism and distance between the two ribs 340. The extension plate 113 can be strip-shaped, with one end connected to the top plate 112. The width of the extension plate 113 can be smaller than the width of the top plate 112. Figure 3 、 Figure 4 As shown, the center of the top plate 112 in the width direction can be connected to one end of the extension plate 113. The other end of the extension plate 113 can extend along the extension direction of the bottom plate 121, away from the top plate 112. The extension plate 113 can be parallel to the bottom plate 121, and the extension plate 113 can be located above the bottom plate 121. Figure 9 、 Figure 10 As shown, the extension plate 113 can penetrate deep into the two rib plates 340 at the end away from the top plate 112, and the two side walls of the extension plate 113 opposite to each other in the width direction can respectively abut against the inner side walls of the two rib plates 340. Whether the parallelism and distance of the rib plates 340 are qualified is determined based on the abutment state of the two side walls of the extension plate 113 opposite to each other in the width direction and the inner side walls of the two rib plates 340.

[0057] Specifically, when the end of the extension plate 113 away from the top plate 112 can extend between the two ribs 340, so that the two side walls of the extension plate 113 in the width direction can respectively abut the inner side walls of the two ribs 340, the distance between the two ribs 340 can be determined to be qualified. When the end of the extension plate 113 away from the top plate 112 cannot extend between the two ribs 340, so that the dimension of the extension plate 113 in the width direction is greater than the distance between the two ribs 340, or when the end of the extension plate 113 away from the top plate 112 extends between the two ribs 340, so that the two side walls of the extension plate 113 in the width direction cannot respectively abut the inner side walls of the two ribs 340, the distance between the two ribs 340 can be determined to be unqualified. When the two side walls of the extension plate 113 in the width direction can respectively abut against the inner side walls of the two ribs 340 without a gap, it can be determined that the parallelism of the inner side walls of the two ribs 340 is qualified. When the two side walls of the extension plate 113 in the width direction can respectively abut against the inner side walls of the two ribs 340 with a gap, it can be determined that the parallelism of the inner side walls of the two ribs 340 is unqualified.

[0058] The inspection tool provided in this embodiment uses the extension plate 113 provided on the top plate 112 to quickly and accurately test the spacing and parallelism between the two ribs 340 on the back side of the push plate 310, thereby determining the pass / fail status of the push plate assembly 300. By inserting the extension plate 113 between the two ribs 340 and contacting their inner sidewalls to determine their parallelism and spacing, the inspection process can be effectively simplified, improving the accuracy and efficiency of the push plate assembly 300 inspection. Furthermore, the provision of the extension plate 113 makes it easier to insert into the narrow space between the ribs 340, making the inspection operation more convenient.

[0059] In some embodiments, a protruding ear seat 350 is formed on the opposite side of the two ribs 340. In order to further improve the strength of the push plate assembly 300, the ear seat 350 can be respectively provided on the two ribs 340, and the ear seat 350 can at least protrude inward toward the opposite side wall of the two ribs 340. Figure 2 、 Figure 7 As shown, the rib plate 340 can be triangular, and one side of the long side can be fixedly connected to the back side of the push plate 310, thereby improving the strength of the push plate 310, and an ear seat 350 can be set at the top corner attachment corresponding to the long side of the rib plate 340, so that the ear seat 350 can protrude inward toward at least the opposite side walls of the two rib plates 340.

[0060] Among them, Figure 2 、 Figure 9 As shown, the first inspection fixture 110 may further include a protruding plate 114, one end of which is connected to the extension plate 113. The width of the protruding plate 114 is smaller than the width of the extension plate 113, and the other end of the protruding plate 114 is configured to extend between the two lugs 350 to detect the parallelism and distance between the two lugs 350. The protruding plate 114 may be connected to the side of the extension plate 113 away from the top plate 112. One end of the protruding plate 114 is connected to the extension plate 113, and the other end may extend downward, allowing the other end of the protruding plate 114 to penetrate into the space between the two ribs 340, thereby extending the protruding plate 114 between the two lugs 350. Since the ear seats 350 can protrude inwardly toward at least the opposite side walls of the two ribs 340, the space between the two ear seats 350 is smaller than the space between the two ribs 340. Therefore, the width of the protruding plate 114 can be smaller than the width of the extension plate 113, so that the protruding plate 114 can extend between the two ear seats 350. The distance and parallelism between the ear seats 350 are determined by the contact between the two opposite side walls of the protruding plate in the width direction and the inner side walls of the ear seats 350.

[0061] Specifically, when one end of the protruding plate 114 can extend between the two ear seats 350, so that the two side walls of the protruding plate 114 in the width direction can respectively abut the inner side walls of the two ear seats 350, the distance between the two ear seats 350 can be determined to be qualified. When the end of the protruding plate 114 away from the extension plate 113 cannot extend between the two ear seats 350, so that the width dimension of the protruding plate 114 is greater than the distance between the two ear seats 350, or when the end of the protruding plate 114 away from the extension plate 113 extends between the two ribs 340, so that the two side walls of the protruding plate 114 in the width direction cannot respectively abut the inner side walls of the two ear seats 350, the distance between the two ear seats 350 can be determined to be unqualified. When the two side walls of the protruding plate 114 in the width direction can respectively abut against the inner side walls of the two ear seats 350 without any gap, it can be determined that the parallelism of the inner side walls of the two ear seats 350 is qualified. When the two side walls of the protruding plate 114 in the width direction can respectively abut against the inner side walls of the two ear seats 350 with a gap, it can be determined that the parallelism of the inner side walls of the two ear seats 350 is unqualified.

[0062] According to the inspection tool provided in this embodiment, the distance and parallelism between the ear seats 350 on the two ribs 340 provided on the back side of the push plate 310 can be quickly and accurately inspected through the protruding plate 114 connected to the extension plate 113, thereby judging whether the push plate assembly 300 is qualified. By inserting the protruding plate 114 between the two ear seats 350 and contacting their inner side walls to judge their parallelism and distance, the inspection process can be effectively simplified, and the accuracy and efficiency of the inspection of the push plate assembly 300 can be improved. In addition, by providing the protruding plate 114, it is easier to insert it into the narrow space between the ear seats 350, making the inspection operation more convenient. The inspection tool provided in this embodiment further improves the inspection accuracy of the push plate assembly 300, helps to confirm its defects before the push plate assembly 300 is put into storage or assembled, reduces the failure rate of the push plate assembly 300, and improves the reliability of the operation of the ore sorting equipment.

[0063] In some embodiments, the width of the extension plate 113 is greater than or equal to 16 mm and less than or equal to 21 mm; and / or the width of the protruding plate 114 is greater than or equal to 13 mm and less than or equal to 18 mm.

[0064] Since the extension plate 113 is used to detect the distance and parallelism between the two ribs 340, the width of the extension plate 113 can be greater than or equal to 16 mm and less than or equal to 21 mm to ensure that the distance between the corresponding ribs 340 meets this requirement, thereby better improving the strength of the push plate assembly 300.

[0065] The two opposite side walls 113 of the first gauge 110 in the width direction abut against the inner side wall of the rib plate 340, as shown in FIG. Figure 9As shown, according to the main view of the working state of the inspection tooling, the width of the extension plate 113 can be 16.5 mm, and the tolerance is -0.5 mm to -0.2 mm. When the two opposite side walls of the extension plate 113 in the width direction of the first inspection fixture 110 abut against the inner wall of the rib plate 340 or there is a small gap, it can be determined that the distance between the rib plates 340 is qualified.

[0066] Since the convex plate 114 is used to detect the distance and parallelism between the two ear seats 350, the width of the convex plate 114 can be greater than or equal to 13mm and less than or equal to 18mm. This ensures that the distance between the corresponding ear seats 350 meets this requirement, thereby better improving the strength of the push plate assembly 300. The convex plate 114 is used to abut the inner side wall of the ear seat 350 on the opposite side walls in the width direction of the first inspection tool 110. Figure 9 、 Figure 10 As shown, the width of the extension plate 113 can be 16.5 mm, and the tolerance is -0.45 mm to -0.4 mm. When the two opposite side walls of the protruding plate 114 in the width direction of the first inspection fixture 110 abut against the inner side walls of the ear seat 350 or there is a small gap, it can be determined that the distance between the ear seats 350 is qualified.

[0067] According to the inspection tool provided in this embodiment, by limiting the width of the extension plate 113, the spacing between the ribs 340 to be detected can be effectively limited, and by the width of the convex plate 114, the width between the ear seats 350 to be detected can be effectively limited. According to the inspection tool provided in this embodiment, by setting the dimensions and controlling the tolerances of multiple key parts of the inspection tool, such as the first side plate 111 and the groove 1211, accurate inspection of the spacing between the ribs 340 and the ear seats 350 can be achieved. The inspection tool provided in this embodiment is easy to operate and ensures the inspection accuracy of the inspection tool, thereby improving the adaptability and reliability of the entire inspection tool during the inspection process of the push plate assembly 300. It can be highly adapted to the factory inspection and assembly calibration scenarios of the push plate assembly 300 of the ore and other material sorting equipment, greatly improving the inspection efficiency and accuracy of the push plate assembly 300.

[0068] In some embodiments, the first side plate 111 and the second side plate 122 are detachably connected by pins; or, the first side plate 111 and the second side plate 122 are hinged. Since the push plate assembly 300 to be tested needs to be installed on the second inspection fixture 120, the first inspection fixture 110 and the second inspection fixture 120 are then installed in conjunction with each other, so that the push plate assembly 300 to be tested is set between the first inspection fixture 110 and the second inspection fixture 120, thereby enabling the first inspection fixture 110, the second inspection fixture 120, and the push plate assembly 300 to be quickly installed and disassembled, thereby further accelerating the inspection of the push plate assembly 300 and achieving more efficient inspection of the push plate assembly 300. The first inspection fixture 110 and the second inspection fixture 120 can be quickly installed by the bottom surface of the first side plate 111 and the top surface of the second side plate 122. Therefore, the first side panel 111 and the second side panel 122 can be detachably connected by pin positioning, thereby effectively saving installation time of the first side panel 111 and the second side panel 122 and achieving quick positioning. A pin hole can be opened on the top surface of one of the second side panels 122, and a pin can be formed on the bottom surface of the corresponding first side panel 111 extending downward to cooperate with the pin hole, so that the pin of the first side panel 111 can be installed in the pin hole of the second side panel 122, thereby achieving the installation of the first side panel 111 and the second side panel 122, so that the bottom surface of the first side panel 111 and the top surface of the second side panel 122 abut against each other. The top surface of the other second side plate 122 can be provided with a pin extending upward, and the bottom surface of the corresponding first side plate 111 is provided with a pin hole, which cooperates with the pin, so that the pin of the second side plate can be installed in the pin hole of the first side plate 111, thereby achieving the installation of the first side plate 111 and the second side plate 122, so that the bottom surface of the first side plate 111 and the top surface of the second side plate 122 abut each other. After the push plate assembly 300 is installed in the second inspection fixture 120, so that the circumference of the pin shaft 320 of the push plate assembly 300 abuts the second arc-shaped groove 1221 of the second side plate 122, the first inspection fixture 110 can be placed on the second inspection fixture 120, so that the first side plate 111 and the second side plate 122 are connected via the pin and the pin hole, achieving rapid positioning and installation of the first side plate 111 and the second side plate 122, and at the same time, the inspection tool can be used to test whether the push plate assembly 300 is qualified. After completing the inspection of one push plate assembly 300, the first side plate 111 can be removed from the second side plate 122, and the next push plate assembly 300 can be replaced and installed on the second inspection fixture 120. The first inspection fixture 110 is then placed on the second inspection fixture 120, and the first side plate 111 and the second side plate 122 are connected through the pins and pin holes to carry out the inspection of the new push plate assembly 300.

[0069] Furthermore, the first side panel 111 and the second side panel 122 can also be hinged at one end near the pivot 330 of the push plate assembly 300, allowing the first side panel 111 to rotate about the hinge point. With the first side panel 111 and the second side panel 122 hinged, the first and second inspection fixtures 110, 120, do not need to be repeatedly disassembled and assembled; the first inspection fixture 110 can rotate about the hinge point. When inspecting the push plate assembly 300, the first inspection fixture 110 can be opened and flipped upward about the hinge point, separating the bottom surface of the first side panel 111 from the top surface of the second side panel 122. The push plate assembly 300 to be tested can then be installed in the second inspection fixture 120, so that the circumference of the pin 320 of the push plate assembly 300 abuts the second arc-shaped groove 1221 of the second side plate 122. The first inspection fixture 110 can then be flipped down and rotated about the hinge point, and then placed on the second inspection fixture 120, so that the bottom surface of the first side plate 111 abuts the top surface of the second side plate 122. At this point, the push plate assembly 300 to be tested is placed between the first inspection fixture 110 and the second inspection fixture 120, and can be tested using the inspection tool. After the inspection of one push plate assembly 300 is completed, the first inspection fixture 110 can be flipped up again so that the first inspection fixture 110 is flipped up around the hinge point, and the bottom surface of the first side plate 111 is separated from the top surface of the second side plate 122. Then, the push plate assembly 300 that has completed the inspection can be removed from the second inspection fixture 120, and another push plate assembly 300 to be inspected can be replaced to continue the inspection.

[0070] According to the inspection tool provided in this embodiment, the first side plate 111 and the second side plate 122 can be quickly combined and separated through a detachable pin connection or a hinged structure, thereby realizing the rapid combination and separation of the first inspection fixture 110 and the second inspection fixture 120, simplifying the inspection process of the push plate assembly 300, and improving the inspection efficiency and operational flexibility of the inspection tool. It is particularly suitable for high-frequency and batch inspection tasks of the push plate assembly 300 in ore sorting equipment, ensuring the stability, efficiency and operability of the inspection work.

[0071] Based on the same inventive concept, Figure 11 As shown, the present disclosure further provides a method for inspecting a push plate assembly, which is applied to an inspection tool as in any of the aforementioned embodiments. The method may include: steps S210 to S240.

[0072] Step S210: Place the push plate of the push plate assembly against the bottom plate, and position the push plate assembly pin in the second arc-shaped groove of the second side plate. First, the striking surface of the push plate of the push plate assembly can be placed against the bottom plate, while the push plate assembly pin can be positioned in the second arc-shaped groove of the second side plate. This allows the push plate assembly to be installed in the second arc-shaped groove, allowing the entire push plate assembly to be mounted on the second inspection fixture.

[0073] In step S220, the first side plate is aligned and abutted against the second side plate, and the first arcuate groove and the second arcuate groove form an axial hole for accommodating the pin. The bottom surface of the first side plate and the top surface of the second side plate can be aligned and abutted against each other, so that the first inspection fixture is installed on the second inspection fixture, and the push plate assembly to be inspected is located between the first inspection fixture and the second inspection fixture. The first arcuate groove and the second arcuate groove can be aligned to form an axial hole for accommodating the pin. The pin of the push plate assembly is disposed in the axial hole.

[0074] Step S230, the flatness of the push plate is detected through the bottom plate. Since the striking surface of the push plate abuts the top surface of the bottom plate, the flatness of the push plate can be detected according to the contact between the top surface of the bottom plate and the striking surface of the push plate by manual observation or image acquisition and recognition. Specifically, when the striking surface of the push plate fits the top surface of the bottom plate without a gap, or the gap is small, it can be determined that the flatness of the striking surface of the push plate is qualified. When the striking surface of the push plate cannot completely fit the top surface of the bottom plate, the gap is large, the gap is uneven, or interference occurs, it can be determined that the flatness of the striking surface of the push plate is unqualified, thereby further determining that the push plate assembly is unqualified.

[0075] Step S240, detect the coaxiality of the pin through the shaft hole. Since the shaft hole is used to detect the coaxiality of the pin of the push plate assembly, the coaxiality of the pin can be detected according to the contact between the shaft hole and the pin by means of manual observation or image acquisition and recognition. Specifically, when the shaft hole abuts the outer peripheral side of the pin, or the gap is small and does not interfere, and the pin can rotate freely in the shaft hole, it can be determined that the coaxiality of the pin is qualified. Finally, the push plate assembly can be determined to be qualified based on the qualified coaxiality test result of the pin and the qualified flatness test result of the push plate. When the assembly gap between the pin of the push plate and the shaft hole is large, the gap is uneven or interference occurs, and the pin cannot rotate freely in the shaft hole, it can be determined that the coaxiality of the pin is unqualified, thereby further determining that the push plate assembly is unqualified.

[0076] According to the method for inspecting the push plate assembly provided by the present embodiment, combined with the base plate, the arc-shaped groove and the inspection fixture structure, the push plate assembly can be positioned in one step, the operation is simpler, and the efficiency of the inspection operation can be effectively improved; the push plate flatness and the pin coaxiality of the push plate assembly are respectively inspected through the base plate and the shaft hole, and the inspection can be achieved through various inspection means such as manual naked eye observation or image recognition system, which can be effectively applied to a variety of different working conditions, improves the adaptability of using the inspection tool to inspect the push plate assembly, and can quickly and easily determine whether the push plate assembly is qualified. The method for inspecting the push plate assembly provided by the present embodiment has a higher inspection efficiency.
