Description

Technical Field

[0001] The invention relates to the technical field of appearance inspection, and in particular to an appearance inspection device for a cylinder head casting. Background Art

[0002] In the field of appearance inspection of existing cylinder head castings, some existing inspection equipment has a simple structure and lacks the ability to conduct all-round and detailed inspection of cylinder head castings; in terms of rotation control of cylinder head castings, existing equipment is either unable to achieve rotation or has insufficient rotation accuracy, making it difficult to meet the requirements of comprehensive and detailed inspection of all sides of cylinder head castings. Moreover, the spatial layout of existing equipment is not reasonable enough, and the components interfere with each other, which not only affects the inspection efficiency, but also increases the floor space and cost of the equipment.

[0003] In terms of the consistency of the inspection process and the coordination of each link, the various inspection links are often independent of each other and lack effective connection, which makes the entire inspection process time-consuming and difficult to meet the demand for inspection efficiency in large-scale production. For example, after spraying the penetrant and developer on the cylinder head casting, there is no appropriate temporary storage and waiting time design, which cannot ensure that the reagents can fully play their role, and it is easy to introduce external impurities during transportation and inspection, which interferes with the inspection results; when spraying reagents on the cylinder head casting to assist in inspection, it is easy to cause uneven reagent spraying and reagent waste, which affects the inspection effect.

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figure 1-10 The cylinder head casting appearance inspection device shown is used to inspect the cylinder head casting, including an inspection platform and a transmission chain 1, a temporary storage chamber 5 and a developing chamber 6 installed on the inspection platform. There are two temporary storage chambers 5 and they are respectively located at the two ends of the inspection platform. There are several groups of mounting modules 2 and they are all arranged on the transmission chain 1. The transmission chain 1 passes through the two temporary storage chambers 5 in turn and is introduced into the developing chamber 6. The transmission chain 1 is two groups of reverse horizontal transmission sections during the initial transmission and when transmitting between the two groups of temporary storage chambers 5. There are two groups of spray mechanisms 4. The spray mechanism 4 for spraying penetrant is arranged beside the first group of horizontal transmission sections of the transmission chain 1, and the spray mechanism 4 for spraying developer is arranged beside the second group of horizontal transmission sections of the transmission chain 1. A cleaning component is arranged in the first temporary storage chamber 5, and an ultraviolet lamp 7 located at the top and a high-definition detection camera 8 located on one side are arranged in the developing chamber 6. Each group of spray mechanisms 4 is provided with a rotating drive mechanism 3 at a symmetrical position along the vertical plane of the transmission chain 1, as shown in FIG. Figure 5-8As shown, the mounting module 2 is composed of a mounting frame 9, a guide wheel 10, a transmission connecting rod 11, a rotating shaft 12 and a hook 13. The guide wheel 10 is horizontally arranged above the mounting frame 9, the mounting frame 9 is slidably arranged on the transmission chain 1, the rotating shaft 12 is vertically rotatably arranged below the mounting frame 9, and the hook 13 is fixedly installed at the bottom of the rotating shaft 12. The guide wheel 10 is fixedly connected to the transmission connecting rod 11, and the bottom end of the transmission connecting rod 11 is rotationally connected to the mounting frame 9. A rotating transmission device 18 and a locking device 19 are installed on the mounting frame 9. The rotating transmission device 18 and the locking device 19 are both transmission-connected to the rotating shaft 12, and the rotating transmission device 18 and the locking device 19 can be transmission-connected to the rotating drive mechanism 3.

[0033] The cylinder head casting is mounted on the mounting module 2 of the transmission chain 1. After the transmission chain 1 is started, the rotating transmission device 18 and the locking device 19 of the mounting module 2 can work in coordination with the rotating drive mechanism 3. This not only realizes the rotation control of the cylinder head casting, but also can accurately control its rotation angle. When the cylinder head casting is transmitted to the first group of horizontal transmission sections, the spraying mechanism 4 starts to spray the penetrant. In this process, the mounting module 2 accurately controls the rotation angle of the cylinder head casting to ensure that the penetrant evenly covers the four sides, so that the penetration effect is more ideal. This process can operate on multiple cylinder head castings simultaneously to improve work efficiency. Subsequently, the cylinder head casting enters the first temporary storage chamber 5. The setting of the temporary storage chamber 5 provides the necessary time for the full penetration of the penetrant, which is the time required for the entire spraying and testing. This waiting time will not affect the progress of other processes. After a period of time, the cleaning component in the temporary storage chamber 5 cleans the impurities on the surface of the cylinder head casting to prevent the impurities from affecting subsequent testing. In the second group of horizontal transmission sections, another spraying mechanism 4 sprays the developer. Similarly, the mounting module 2 ensures that the developer is evenly sprayed on all sides of the cylinder head casting, laying a good foundation for the development process. After entering the developing chamber 6, the ultraviolet lamp 7 irradiates to enhance the development effect. At the same time, the rotary drive mechanism 3 rotates the cylinder head casting in all directions through the relevant devices of the mounting module 2, and the high-definition detection camera 8 shoots its surface to complete a comprehensive appearance inspection.

[0034] The spray mechanism 4 relies on precise spraying technology, combined with the precise control of the rotation angle of the cylinder head casting by the mounting module 2, to ensure that the reagent is evenly sprayed on the four sides, greatly improving the accuracy of the detection. Cooperating with the ultraviolet lamp 7 and the high-definition detection camera 8 in the developing room 6, high-precision detection is achieved. The design of the two temporary storage rooms 5 leaves sufficient time for the penetrant and developer to take effect, ensuring that there is a suitable interval between the various processing links of the cylinder head casting to avoid interference between different links. The entire equipment has a compact structure and the components are closely matched, which can complete the continuous detection process, from the mounting, transportation, spraying to the detection of the cylinder head casting, all in one go, ensuring accurate detection of the surface of the cylinder head casting, and effectively improving the detection efficiency and quality.

[0035] It is worth mentioning that the internal transmission mode of the temporary storage chamber 5 shown in the present invention can be spiral, and the outlet can be set at its top or bottom, so the subsequent spraying mechanism 4 can be installed directly above the previous process, so as to achieve the effect of saving plane space.

[0036] The rotation drive mechanism 3 includes a rotation drive component and an unlocking component. The unlocking component is installed on the detection platform. The rotation drive component is arranged on the output end of the unlocking component. The unlocking component is transmission-connected to the locking device 19 , and the rotation drive component is transmission-connected to the rotation transmission device 18 .

[0037] The unlocking assembly is connected to the locking device 19 by transmission. When the cylinder head casting is transported to a specific position and needs to be rotated, the unlocking assembly can accurately unlock the locking device 19. This process breaks the locking state of the locking device 19 on the rotating shaft 12, so that the rotating shaft 12 can be driven to rotate in the future, thereby driving the cylinder head casting mounted thereon to rotate. After unlocking, the rotation drive assembly can transmit its own power to the rotating shaft 12 through the rotation transmission device 18, thereby realizing precise control of the rotation angle of the cylinder head casting.

[0038] During the reagent spraying stage of the spray mechanism 4, the rotary drive assembly can accurately control the rotation speed and angle of the cylinder head casting according to the preset program to ensure that the penetrant and developer can evenly cover the four sides of the cylinder head casting. When testing in the developing chamber 6, the rotary drive assembly can drive the cylinder head casting to rotate in all directions, allowing the high-definition detection camera 8 to capture every detail of the surface of the cylinder head casting to avoid detection blind spots.

[0039] This design not only improves the uniformity of the spraying process, ensuring that the detection reagents can be accurately and evenly sprayed on the surface of the cylinder head casting, but also greatly improves the comprehensiveness and accuracy of the detection process, providing strong support for ensuring the appearance inspection quality of the cylinder head casting.

[0040] The locking device 19 includes a vertical fixed plate 20 vertically fixedly mounted on the mounting frame 9 and a vertical sliding frame 21 horizontally slidably arranged on the mounting frame 9. The sliding direction of the vertical sliding frame 21 is perpendicular to the transmission direction of the transmission chain 1. The vertical fixed plate 20 is located on the side of the mounting frame 9 close to the spray mechanism 4, and the vertical sliding frame 21 is located on the side of the vertical fixed plate 20 away from the spray mechanism 4. The vertical sliding frame 21 is slidably matched with the mounting frame 9 through a sliding limit frame 22. A spring 23 is provided between the vertical sliding frame 21 and the vertical fixed plate 20. The two ends of the spring 23 are respectively engaged with the vertical sliding frame 21 and the vertical fixed plate 20. The frame 21 is fixedly connected to the vertical fixed plate 20, a first clamping block 24 is fixedly installed on the vertical sliding frame 21, a limiting ring 25 is fixedly sleeved on the rotating shaft 12, a plurality of first clamping grooves 26 which are engaged with the first clamping block 24 are annularly arranged on the limiting ring 25, an unlocking component includes a plug rod 27 which can be extended horizontally, a avoidance hole 28 for avoiding the plug rod 27 is provided on the vertical fixed plate 20, a flared chamfer 29 is provided on the side of the avoidance hole 28 close to the spray mechanism 4, the plug rod 27 is in contact with the vertical sliding frame 21, and an insertion tip is provided on the side of the plug rod 27 close to the mounting frame 9.

[0041] The vertical fixing plate 20 plays a role in stable support and positioning. The vertical sliding frame 21 realizes sliding cooperation with the mounting frame 9 through the sliding limit frame 22. In the initial state, the first clamping block 24 will be clamped into one of the first clamping grooves 26 under the elastic force of the spring 23, thereby limiting the rotation of the rotating shaft 12, locking the cylinder head casting, and ensuring that it will not rotate at will during transportation. When the cylinder head casting needs to be rotated, the insertion rod 27 extends horizontally. Due to the guidance of the flared chamfer 29, the insertion rod 27 smoothly passes through the avoidance hole 28 and uses its insertion tip to resist the vertical sliding frame 21. As the insertion rod 27 continues to go deeper, it pushes the vertical sliding frame 21 to overcome the elastic force of the spring 23 and slide in the direction away from the spray mechanism 4. In this process, the first clamping block 24 gradually disengages from the first clamping groove 26 of the limit collar 25, thereby releasing the lock on the rotating shaft 12. At this time, the rotary drive assembly can drive the rotary shaft 12 to rotate through the rotary transmission device 18, thereby realizing the rotation control of the cylinder head casting.

[0042] The design of the avoidance hole 28 on the vertical fixing plate 20 and the flared chamfer 29 provided thereon makes it smoother to insert the insertion rod 27 into the avoidance hole 28, can effectively guide the insertion direction of the insertion rod 27, and can ensure that the insertion rod 27 locks the vertical fixing plate 20 after insertion. The unlocking component also drives the rotation drive component to the rotating shaft 12 while unlocking, so that the rotation drive component can drive the rotating shaft 12 to rotate. The design of this locking device 19 and the unlocking component not only ensures the stability of the cylinder head casting during transportation and prevents it from accidentally rotating, but also can quickly and accurately unlock it when a rotation operation is required, providing strong support for the subsequent spraying and testing links. It further optimizes the workflow of the entire device, improves the collaborative work efficiency between the components, and effectively guarantees the accuracy and efficiency of the appearance inspection of the cylinder head casting.

[0043] The unlocking assembly also includes a first mounting frame 30, a first linear drive 31, a pushing frame 32 and a rotating rod 33. The first mounting frame 30 is fixedly mounted on the detection platform, the first linear drive 31 is horizontally fixedly mounted on the first mounting frame 30, the pushing frame 32 is slidably arranged on the first mounting frame 30, the output end of the first linear drive 31 is fixedly connected to the pushing frame 32, the sliding direction of the pushing frame 32 is consistent with the sliding direction of the vertical sliding frame 21, the insertion rod 27 is fixedly mounted on the pushing frame 32, the rotating rod 33 is axially connected to the pushing frame 32, the extending length of the rotating rod 33 is consistent with that of the insertion rod 27, a clamping strip 34 is provided on the outer side wall of the rotating rod 33, a rotating ring 35 is rotatably mounted on the avoidance hole 28 corresponding to the rotating rod 33 on the vertical fixed plate 20, and a second clamping groove 36 cooperating with the clamping strip 34 is provided on the inner side wall of the rotating ring 35, the rotation drive assembly is transmission-connected to the rotating rod 33, and the rotating ring 35 is transmission-connected to the rotating shaft 12 through the rotating transmission device 18.

[0044] The insertion rod 27 is fixedly mounted on the pushing frame 32. When the first linear drive 31 is started and pushes the pushing frame 32 to slide, the insertion rod 27 can be extended horizontally, as described above, to achieve the unlocking operation of the vertical sliding frame 21. The rotating rod 33 is axially connected to the pushing frame 32, and its extension length is consistent with that of the insertion rod 27. This design ensures the coordination of the two in spatial position. The outer wall of the rotating rod 33 is provided with a clamping strip 34, and correspondingly, a rotating ring 35 is rotatably mounted at the avoidance hole 28 on the vertical fixed plate 20, and the inner wall of the rotating ring 35 is provided with a second clamping groove 36 that cooperates with the clamping strip 34. When the pushing frame 32 pushes the insertion rod 27 to extend, the rotating rod 33 reaches the corresponding position synchronously, and the clamping strip 34 will be clamped into the second clamping groove 36, so that the rotating rod 33 and the rotating ring 35 are connected in transmission.

[0045] When the cylinder head casting needs to be rotated, the rotary drive assembly first drives the rotary rod 33 to rotate, and the rotary rod 33 drives the rotary ring 35 to rotate through the cooperation of the clamping bar 34 and the second clamping groove 36. The rotary ring 35 then drives the rotary shaft 12 via the rotary transmission device 18, thereby finally realizing the rotation control of the cylinder head casting.

[0046] The rotating transmission device 18 includes a driving bevel gear 37, a first driven bevel gear 38, a second rotating shaft 39 and a second driven bevel gear 40. The driving bevel gear 37 is fixedly mounted on the rotating ring 35. Two first driven bevel gears 38 are provided. The second rotating shaft 39 is horizontally and rotatably mounted on the mounting frame 9. The two first driven bevel gears 38 are fixedly mounted at both ends of the second rotating shaft 39. The second driven bevel gear 40 is fixedly mounted on the rotating shaft 12. The driving bevel gear 37 is meshed with one of the first driven bevel gears 38, and the other first driven bevel gear 38 is meshed with the second driven bevel gear 40.

[0047] When the rotary drive assembly drives the rotary rod 33 to rotate, the rotary ring 35 rotates accordingly, thereby driving the driving bevel gear 37 fixed thereon to rotate. The rotation of the driving bevel gear 37 is transmitted to the corresponding first driven bevel gear 38 through a meshing relationship. Since the two first driven bevel gears 38 are fixed at both ends of the same second rotating shaft 39, the rotation of the first driven bevel gear 38 will drive the second rotating shaft 39 to rotate, and the rotation of the second rotating shaft 39 will drive another first driven bevel gear 38 to rotate. The other first driven bevel gear 38 is meshed with the second driven bevel gear 40, thereby transmitting power to the second driven bevel gear 40, and finally driving the rotating shaft 12 to rotate, thereby realizing the rotation control of the cylinder head casting.

[0048] This design can not only accurately control the rotation angle and speed of the cylinder head casting, and meet the precise requirements for the rotation of the cylinder head casting in the spraying and testing links, but also has a compact structure, is installed on the mounting frame 9, and cooperates with other components to further optimize the spatial layout of the entire device. It works closely with the unlocking component and other related components, so that the entire device can quickly and accurately achieve seamless connection between unlocking and rotation drive while ensuring the stability of the transportation of the cylinder head casting, greatly improving the collaborative work efficiency between the components, and providing a more solid guarantee for the accuracy and efficiency of the appearance inspection of the cylinder head casting.

[0049] The rotary drive assembly includes a motor mounting frame 41, a rotary driver 42 and a synchronous belt 43. A plurality of rotary rods 33 and insertion rods 27 are mounted on the pushing frame 32. The rotary rods 33 and insertion rods 27 correspond one to one. The motor mounting frame 41 is fixedly mounted on the pushing frame 32. The rotary driver 42 is fixedly mounted on the motor mounting frame 41. The output end of the rotary driver 42 is fixedly connected to one of the rotary rods 33. The remaining rotary rods 33 are transmission-connected to the output end of the rotary driver 42 via the synchronous belt 43.

[0050] When the rotary driver 42 is started, the rotary rod 33 directly connected to the output end rotates first, and then transmits power to other rotary rods 33 through the synchronous belt 43, so that all rotary rods 33 can rotate at the same speed and angle. As mentioned above, the rotary rod 33 and the rotating ring 35 are connected by the clamping strip 34 and the second clamping groove 36, and the rotating ring 35 is connected by the rotating shaft 12 through the rotating transmission device 18. Therefore, when the rotary drive assembly drives all the rotary rods 33 to rotate, the rotating ring 35 rotates accordingly, thereby driving the driving bevel gear 37 to rotate. The driving bevel gear 37 transmits power to the rotating shaft 12 through the meshing relationship with the first driven bevel gear 38 and the second driven bevel gear 40, and finally realizes the precise rotation control of the cylinder head casting mounted on the hook 13.

[0051] The spray mechanism 4 includes a reagent spray head 44, an introduction pipe 45, a first water receiving tank 46, a second linear drive 48, a sliding plate 49 and a second mounting frame 56. The first water receiving tank 46 is arranged directly below the transmission chain 1, and the second mounting frame 56 (such as Figure 4 As shown in the figure, the second linear drive 48 is installed on the detection platform and is located beside the rotation drive mechanism 3. The second linear drive 48 is fixedly installed on the second mounting frame 56. The sliding plate 49 is slidably set on the second mounting frame 56. The output end of the second linear drive 48 is fixedly connected to the sliding plate 49. The sliding direction of the sliding plate 49 is consistent with the transmission direction of the transmission chain 1. A plurality of reagent spray heads 44 are provided and correspond to a plurality of rotating rods 33 one by one. The reagent spray heads 44 are all vertically fixedly installed on the sliding plate 49. The introduction pipe 45 is connected to the plurality of reagent spray heads 44. A vertical baffle 47 is vertically provided on the side of the first water receiving trough 46 away from the reagent spray head 44. The second mounting frame 56 is also provided with an adjustment component for adjusting the spraying range of the reagent spray head 44.

[0052] After the rotary drive assembly drives the cylinder head casting to rotate, the spray mechanism 4 can accurately spray the reagent on the surface of the cylinder head casting. After each rotation in one direction, the reagent spray head 44 sprays one side of the cylinder head casting. The second linear drive 48 drives the sliding plate 49 to move, driving the reagent spray head 44 fixed thereon to slide horizontally synchronously, and adjusting the spraying range of the reagent spray head 44 according to the horizontal width of the side of the cylinder head casting. The first water receiving trough 46 is arranged directly below the transmission chain 1. Its main function is to receive excess reagents during the spraying process and prevent the reagents from dripping onto the detection platform or other equipment, thereby keeping the working environment clean and tidy and avoiding reagent waste. The function of the vertical baffle 47 is to further prevent excess reagents from splashing out of the water receiving trough range, thereby enhancing the effect of the water receiving trough in collecting reagents. The second mounting frame 56 is also provided with an adjustment component for adjusting the spraying range of the reagent spray head 44. The adjustment component can flexibly adjust the spraying range of the reagent spray head 44 according to cylinder head castings of different sizes and shapes, ensuring that the reagent can be evenly and comprehensively covered on the surface of the cylinder head casting. The spray mechanism 4 is closely integrated with the rotary drive component and the transportation system of the entire device through the coordinated cooperation of the above-mentioned various components.

[0053] The adjustment component includes an electric push rod 50, a lifting plate 51, a sealing plate 52 and a locking slide 53. The electric push rod 50 is vertically mounted on the second mounting frame 56. The lifting plate 51 can be lifted and lowered on the second mounting frame 56. The output end of the electric push rod 50 is fixedly connected to the lifting plate 51. There are a plurality of sealing plates 52 and locking slides 53, which correspond to a plurality of reagent spray heads 44 one by one. The locking slide 53 is fixedly mounted on the reagent spray head 44. The sealing plate 52 is slidably matched with the nozzle of the reagent spray head 44 through the locking slide 53. A plurality of sealing plates 52 are slidably arranged on the lifting plate 51.

[0054] When it is necessary to increase the spraying range of the reagent spray head 44, the electric push rod 50 pushes the lifting plate 51 down. At this time, the sealing plate 52 connected to the lifting plate 51 also drops, so that the sealing plate 52 reduces the blocking area of ​​the nozzle of the reagent spray head 44, so that the reagent can be sprayed at a larger angle and range, meeting the spraying requirements of larger-sized cylinder head castings. Conversely, when it is necessary to reduce the spraying range, the electric push rod 50 pushes the lifting plate 51 up, and the sealing plate 52 rises, increasing the blocking area of ​​the nozzle of the reagent spray head 44, so that the spraying range of the reagent becomes smaller, which is suitable for the precise spraying of cylinder head castings with smaller sizes or special shapes. The adjustment component can flexibly and accurately adjust the spraying range of the reagent spray head 44 according to the actual needs of different cylinder head castings, which can not only ensure that the spraying is in place, but also prevent the waste of reagents caused by excessive spraying range.

[0055] The side wall of the mounting frame 9 is fixedly mounted with a contact extrusion plate 57 (such as Figure 8As shown in the figure, the openings of the temporary storage chamber 5 and the developing chamber 6 are both provided with sealing mechanisms, which include a shielding door 58, a hinge shaft 59 and a torsion spring 60. The shielding door 58 is connected to the openings of the temporary storage chamber 5 and the developing chamber 6 through the hinge shaft 59, the shielding door 58 is fixedly connected to the hinge shaft 59, the torsion spring 60 is sleeved on the hinge shaft 59 and fixedly connected to the temporary storage chamber 5 and the developing chamber 6, a U-shaped guide rail 54 and a second water receiving trough 55 are also provided in the temporary storage chamber 5, a plurality of U-shaped guide rails 54 are provided and are reversely docked in sequence, the second water receiving trough 55 is located directly below the U-shaped guide rail 54, the end of the U-shaped guide rail 54 is connected to the transmission guide rail 14, a hot air channel 61, a cleaning spray head 62 and a partition 63 are also fixedly provided in the temporary storage chamber 5, and the cleaning spray head 62 is deflectably installed on the partition 63.

[0056] The sealing mechanism is set at the opening of the temporary storage chamber 5 and the developing chamber 6. Under normal conditions, the elastic force of the torsion spring 60 keeps the shielding door 58 closed, effectively preventing foreign matter from entering the temporary storage chamber 5, and reducing the brightness inside the developing chamber 6, improving the development detection effect, and avoiding interference with the cylinder head casting that is undergoing penetration, development or detection. When the mounting module 2 on the transmission chain 1 brings the cylinder head casting close to the opening of the temporary storage chamber 5 or the developing chamber 6, the contact squeeze plate 57 will push the shielding door 58 to rotate around the hinge shaft 59, overcome the elastic force of the torsion spring 60, open the shielding door 58, and smoothly enter the room. When the cylinder head casting is fully entered, the shielding door 58 is automatically closed under the action of the torsion spring 60 to restore the sealed state.

[0057] The U-shaped guide rail 54 and the second water receiving trough 55 provided inside the temporary storage chamber 5 play a key role in the temporary storage of the cylinder head casting and the collection of the waste liquid after cleaning. A plurality of U-shaped guide rails 54 are provided and are reversely connected in sequence, and their ends are connected to the transmission guide rail 14. This enables the mounting module 2 to smoothly move the cylinder head casting along the U-shaped guide rail 54 and perform different stages of processing in the temporary storage chamber 5.

[0058] The cleaning spray head 62 can effectively remove the penetrant on the surface of the cylinder head casting, providing a clean test object for the subsequent testing process. The hot air channel 61 plays a role after the cleaning is completed. By blowing hot air, the surface of the cylinder head casting is accelerated to dry, improving work efficiency, while also avoiding the influence of residual moisture on the subsequent test results.

[0059] The transmission chain 1 is provided with a transmission guide rail 14 fixedly installed on the detection platform and a transmission chain 16 slidably set on the transmission guide rail 14. A plurality of clamping transmission blocks 17 are arranged at intervals on the transmission chain 16. The top end of each transmission connecting rod 11 is clamped with a clamping transmission block 17 on the transmission chain 16. The transmission guide rail 14 is provided with a limiting slide groove 15 for the transmission connecting rod 11 to pass through. The guide wheel 10 is arranged above the transmission guide rail 14, and the mounting frame 9 is located below the transmission guide rail 14.

[0060] The transmission chain 16 drives the clamping transmission block 17 arranged thereon to be displaced during transmission, and drives the clamping transmission connecting rod 11 to be displaced through the clamping transmission block 17, thereby driving the synchronous displacement of the mounting frame 9 connected to the transmission connecting rod 11. The guide wheel 10 is used to guide and limit the mounting module 2 to realize the transmission function, and the stability of the mounting frame 9 can be ensured by the transmission guide rail 14.
