Description

Technical Field

[0001] This utility model relates to the field of testing tools, specifically to a device for detecting the misalignment of irregularly shaped parts. Background Technology

[0002] In the manufacturing of irregularly shaped parts, mold misalignment is a common and serious problem that significantly impacts product quality. Mold misalignment causes deviations in the dimensions and shape of irregularly shaped parts, affecting subsequent assembly accuracy and overall performance, reducing product yield, and increasing production costs. Currently, there are many shortcomings in the market for detecting mold misalignment in irregularly shaped parts. Some devices can only detect from a single direction, failing to comprehensively acquire mold misalignment information, making it difficult to detect hidden mold misalignments, resulting in inaccurate test results. Some devices are complex in structure and cumbersome to operate; for example, the connecting rod mold misalignment detection tool with Chinese patent authorization announcement number CN 214407242 U requires high professional skills from operators, increasing testing costs and reducing efficiency. Furthermore, most existing testing devices lack flexibility and adaptability, making it difficult to meet the testing needs of irregularly shaped parts of different specifications and sizes, and unable to cope with diverse production situations. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a device for detecting the misalignment of irregularly shaped parts.

[0004] The technical solution adopted in this utility model is as follows: A device for detecting the misalignment modulus of irregularly shaped parts includes a tool table, on which a detection device and a positioning seat are mounted side by side, wherein: The positioning base is columnar and used to fix the irregularly shaped part to be inspected, and the irregularly shaped part is placed horizontally. The detection device includes a transverse detection unit and a longitudinal detection unit arranged at 90°, wherein: The transverse detection unit includes a support frame I, and a detection end I and a dial indicator end I disposed on the support frame I. The detection end I is transversely mounted on the support frame I and abuts against the surface of the irregular part. The dial indicator end I is used to read the error modulus. The longitudinal detection unit includes a support frame II, and a detection end II and a dial indicator end II disposed on the support frame II. The detection end II is horizontally mounted on the support frame II and abuts against the surface of the irregular part. The dial indicator end II is used to read the error modulus.

[0005] This technical solution uses a positioning seat to horizontally fix the irregularly shaped part, establishing a stable detection benchmark. Then, using transverse and longitudinal detection units distributed at 90°, the detection ends contact the surface of the irregularly shaped part from two perpendicular directions, transmitting the displacement caused by mold misalignment to the dial indicator, thereby obtaining the mold misalignment data. Specifically, the positioning seat fixes the irregularly shaped part to ensure its stable position, providing a benchmark for detection; the transverse and longitudinal detection units are set at 90°, utilizing the principle of a spatial rectangular coordinate system to detect the irregularly shaped part from two mutually perpendicular directions; the detection ends contact the surface of the irregularly shaped part, transmitting minute displacements to the dial indicator, which displays the mold misalignment value, enabling rapid measurement of the mold misalignment condition of the irregularly shaped part.

[0006] In addition, the irregular part misalignment detection device proposed above according to this utility model also has the following additional technical features: According to one embodiment of the present invention, the positioning seat is provided with a retaining edge that cooperates with the irregularly shaped part, and the irregularly shaped part is confined within the retaining edge.

[0007] In this technical solution, the retaining edge is temporarily replaced as needed for the irregularly shaped part. During installation, it is fitted onto the positioning seat and fixed in place. Utilizing the contact friction between the retaining edge and the surface of the irregularly shaped part, as well as the constraint force generated by the shape fit, the irregularly shaped part is confined within the space defined by the retaining edge.

[0008] According to one embodiment of the present invention, the tool table surface is further provided with a groove for placing a calibration block. Before inspecting irregularly shaped parts, the calibration block is first placed on the positioning seat for calibration.

[0009] In this technical solution, the calibration block is equipped with a magnet, which attracts it to the groove for placement. When needed, the calibration block is placed in the positioning seat, and the detection device performs zeroing and calibration using the known precise parameters of the calibration block.

[0010] According to one embodiment of the present invention, a slide rail is provided on the tool table, and a positioning seat is slidably mounted on the slide rail for adjusting the distance between the positioning seat and the detection device to accommodate the detection of irregularly shaped parts of different lengths.

[0011] In this technical solution, when the detection end I and detection end II are moved to the outermost edge and are still insufficient to accommodate the irregularly shaped part, the position of the positioning seat needs to be adjusted. This allows for the detection of irregularly shaped parts of different lengths on the same tool table, saving costs.

[0012] According to one embodiment of the present invention, a locking mechanism is provided on the slide rail, which is used to lock and fix the positioning seat after it is adjusted to the designated position.

[0013] In this technical solution, the locking mechanism is a screw installed on the side of the tool table. When the locking function is performed, the screw is driven to approach the side of the slide rail along its axis by rotating the screw. As the screw is gradually screwed in, its end contacts the surface of the slide rail side and generates a reverse force, forming a frictional force between the contact surface of the screw and the slide rail side. At the same time, the screw's screwing process also imparts a certain preload.

[0014] According to one embodiment of the present invention, both the support frame I and the support frame II are provided with a height adjustment mechanism. The height adjustment mechanism is used to adjust the height of the detection end I and the detection end II to adapt to the detection of irregularly shaped parts of different heights.

[0015] According to one embodiment of the present invention, the height adjustment mechanism includes a threaded rod and a nut, with support frame I and support frame II respectively sleeved on the corresponding threaded rod, and the height of support frame I and support frame II is adjusted by rotating the nut.

[0016] This technical solution allows for rapid adjustment of the detection end height for irregularly shaped parts of different heights, enabling one device to detect various height specifications of irregularly shaped parts, reducing equipment investment and replacement costs. Height adjustment can be completed simply by rotating the nut, making the operation simple and easy to understand, requiring no professional training, and saving adjustment time and labor costs.

[0017] Compared with the prior art, this utility model has the following advantages: This invention establishes a stable benchmark by horizontally fixing the irregularly shaped part with a positioning seat. It utilizes transverse and longitudinal detection units distributed at 90° to make the detection end contact the surface of the irregularly shaped part from two vertical directions, transmitting the misalignment displacement to the dial indicator end. Then, with the help of edge limiting, calibration block to correct the reading, slide rail to adjust the position of the positioning seat, locking mechanism to fix, and height adjustment mechanism to change the height of the detection end, it realizes the rapid measurement of the misalignment of the irregularly shaped part.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1 like Figures 1 to 2 As shown, this embodiment provides a misalignment detection device for irregularly shaped parts, including a tool table 1, on which a detection device 2 and a positioning seat 3 are mounted side by side, wherein: The positioning seat 3 is columnar and is used to fix the irregular part 4 to be inspected, and the irregular part 4 is placed horizontally. The detection device 2 includes a transverse detection unit and a longitudinal detection unit arranged at 90°, wherein: The transverse detection unit includes a support frame I21, and a detection end I and a dial indicator end I disposed on the support frame I21. The detection end I is transversely mounted on the support frame I21 and abuts against the surface of the irregular part 4. The dial indicator end I is used to read the error modulus.

The detection end II is horizontally mounted on the support frame II and abuts against the surface of the irregular part 4. The dial indicator end II 26 is used to read the error modulus.

[0023] like Figures 1 to 2 As shown, this technical solution uses a positioning base 3 to horizontally fix the irregularly shaped part 4, establishing a stable detection benchmark. Then, using transverse and longitudinal detection units distributed at 90°, the detection ends contact the surface of the irregularly shaped part 4 from two perpendicular directions, transmitting the displacement caused by the mold misalignment to the dial indicator, thereby obtaining the mold misalignment data. Specifically, the positioning base 3 fixes the irregularly shaped part 4 to ensure its stable position, providing a benchmark for detection; the transverse and longitudinal detection units are set at 90°, utilizing the principle of a spatial rectangular coordinate system to detect the irregularly shaped part 4 from two mutually perpendicular directions; the detection ends contact the surface of the irregularly shaped part 4, transmitting minute displacements to the dial indicator, which displays the mold misalignment value, achieving rapid measurement of the mold misalignment condition of the irregularly shaped part 4.

[0024] In addition, the irregular part misalignment detection device proposed above according to this utility model also has the following additional technical features: According to one embodiment of the present invention, the positioning seat 3 is provided with a retaining edge that cooperates with the irregularly shaped part 4, and the irregularly shaped part 4 is confined within the retaining edge.

[0025] In this technical solution, the retaining edge is temporarily replaced according to the needs of the irregular part 4. During installation, it is sleeved on the positioning seat 3 and fixed. By utilizing the contact friction between the retaining edge and the surface of the irregular part 4, as well as the constraint force generated by the shape fit, the irregular part 4 is confined within the space defined by the retaining edge.

[0026] According to one embodiment of the present invention, the tool table 1 is further provided with a groove for placing a calibration block. Before inspecting the irregular part 4, the calibration block is placed on the positioning seat 3 for calibration operation.

[0027] In this technical solution, the calibration block is equipped with a magnet, which attracts it to the groove for placement. When needed, the calibration block is placed in the positioning seat 3, and the detection device 2 performs zeroing and calibration using the known precise parameters of the calibration block.

[0028] According to one embodiment of the present invention, a slide rail is provided on the tool table 1, and the positioning seat 3 is slidably installed on the slide rail to adjust the distance between the positioning seat 3 and the detection device 2 to adapt to the detection of irregular parts 4 of different lengths.

[0029] In this technical solution, when the detection end I and detection end II are moved to the outermost edge but are still insufficient to accommodate the irregular part 4, the position of the positioning seat 3 needs to be adjusted. This allows for the detection of irregular parts 4 of different lengths on the same tool table 1, saving costs.

[0030] According to one embodiment of the present invention, a locking mechanism is provided on the slide rail, which is used to lock and fix the positioning seat 3 after it is adjusted to the designated position.

[0031] In this technical solution, the locking mechanism is a screw installed on the side of the tool table 1. When the locking function is performed, the screw is driven to approach the side of the slide rail along its axis by rotating the screw. As the screw is gradually screwed in, its end contacts the surface of the slide rail side and generates a reverse force, forming a frictional force between the contact surface of the screw and the slide rail side. At the same time, the screw's screwing process also imparts a certain preload.

[0032] According to one embodiment of the present invention, both the support frame I 21 and the support frame II are provided with a height adjustment mechanism. The height adjustment mechanism is used to adjust the height of the detection end I and the detection end II to adapt to the detection of irregular parts 4 of different heights.

[0033] According to one embodiment of the present invention, the height adjustment mechanism includes a threaded rod and a nut. Support frame I 21 and support frame II are respectively sleeved on the corresponding threaded rod, and the height of support frame I 21 and support frame II is adjusted by rotating the nut.

[0034] This technical solution allows for rapid adjustment of the detection end height based on the different heights of the irregularly shaped parts 4, enabling one device to detect various height specifications of irregularly shaped parts 4, reducing equipment investment and replacement costs; height adjustment can be completed simply by rotating the nut, making the operation simple and easy to understand, requiring no professional training, and saving adjustment time and labor costs.

[0035] The usage process of the above embodiments is as follows: like Figures 1 to 2 As shown, before testing, the calibration block adsorbed in the groove of the tool table 1 is taken out and then placed into the positioning seat 3 for zeroing and calibration of the reading; according to the specifications of the irregular part 4, if the length exceeds the limit, push the positioning seat 3 to slide on the slide rail to the appropriate position, and rotate the side screw of the tool table 1 to lock the positioning seat 3; if the height does not match, rotate the nut on the support frame to adjust the height of the testing end by using the thread transmission. During operation, the matching flange is first fixed on the positioning seat 3, and the irregular part 4 to be inspected is placed horizontally on the positioning seat 3. The irregular part 4 is limited by the contact friction between the flange and the surface of the irregular part 4 and the constraint force generated by the shape fit, thus establishing a stable inspection benchmark. Then, the inspection end I of the transverse inspection unit is horizontally mounted on the support frame I 21 and abuts against the surface of the irregular part 4, and the inspection end II of the longitudinal inspection unit is horizontally mounted on the support frame II and abuts against the surface of the irregular part 4 in another vertical direction. When the irregular part 4 has a misalignment, the small displacement caused by the misalignment will be transmitted to the inspection end I and the inspection end II respectively, and then to the dial indicator end I and the dial indicator end II 26. Since the transverse and longitudinal inspection units are set at 90°, the irregular part 4 is inspected from two mutually perpendicular directions using the principle of the spatial rectangular coordinate system. Finally, the misalignment value is displayed through two dial indicators, which is simple and convenient.

[0036] Although the present invention has been described in detail with reference to the accompanying drawings and preferred embodiments, it is not limited thereto. Various equivalent modifications or substitutions can be made to the embodiments of the present invention by those skilled in the art without departing from the spirit and essence of the present invention, and such modifications or substitutions should all be within the scope of the present invention. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should also be included within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the scope of the claims.
