Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a transmission housing clamping device. Background Art

[0002] As the core component of a car, the automobile transmission plays a vital role in the power, economy, stability and environmental protection of the car. The transmission housing is an important part of the transmission. With the development of the automobile industry, automated production has become the mainstream. In order to improve production efficiency, it is necessary to develop automated clamping equipment that can adapt to transmission housings of different sizes.

[0003] However, the existing clamping equipment has the following problems when handling the transmission housing: the transmission housing usually has an irregular columnar structure, the upper and lower ends of transmission housings of different specifications have different diameters, and there are intricate reinforcement ribs distributed on the outer peripheral wall of the transmission housing. At the same time, symmetrically arranged process holes are opened on both sides of the transmission housing. Due to the irregular shape of the outer wall of the transmission housing and the lack of a flat clamping surface, the housing cannot be clamped using ordinary clamps. When the clamp moves, the housing will rotate around the clamping axis and fall off, affecting the safety of the production process. The existing operating method can only use ropes and hoists to manually lift the housing, which is time-consuming and labor-intensive, has low operating efficiency, and cannot be coordinated with the automated production line.

[0004] In summary, developing a clamping device that can overcome the drawbacks of the prior art and achieve a stable clamping of a transmission housing with an irregular clamping surface is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] The purpose of the utility model is to solve the problems of difficult and loose clamping when the existing clamping device processes the transmission housing, and to provide an automatic clamping device which can firmly clamp the transmission housing with irregular outer wall shape.

[0006] To solve the above problems, the utility model provides a transmission case clamping device, comprising a base and a clamping mechanism for clamping both sides of the outer wall of the transmission case, the clamping mechanism comprising a pair of clamping arms arranged at the front end of the base and a driving mechanism arranged on the base for driving the pair of clamping arms to open and close left and right, an ejection mechanism is arranged between the pair of clamping arms, the ejection mechanism comprises a fixing frame fixedly arranged at the front end of the base, a push cylinder arranged on the fixing frame with the output end facing forward, a vertical plate fixedly arranged at the output end of the push cylinder, and at least two ejection blocks arranged at the front end of the vertical plate at upper and lower intervals, a contour block matched with the shape of the rear end of the outer wall of the transmission case is fixedly arranged at the front end of the ejection block, and a pin for inserting into the process holes on both sides of the outer wall of the transmission case is fixedly arranged at the front end of the clamping arm.

[0007] Compared with the prior art, the utility model is advantageous in that: in view of the problem that the prior art cannot effectively clamp the transmission housing, the utility model solves the problems of difficult clamping and loose clamping by providing a pair of clamping arms and an ejection mechanism. When in use, the pins on the clamping arms can be inserted into the process holes on both sides of the housing, and the ejection mechanism closely fits the rear end of the outer wall of the housing through a plurality of ejection blocks and contour blocks to provide necessary supporting force, ensuring that the housing will not rotate or fall off during the clamping process. At the same time, the utility model uses a driving mechanism to control the left and right opening and closing of the clamping arms, and a push cylinder to control the forward and backward movement of the ejection block, thereby realizing automatic clamping, avoiding the time-consuming and labor-intensive problems caused by manual lifting of the housing, improving production efficiency, and being able to better cooperate with automated production lines.

[0008] Specifically, the driving mechanism is a pair of telescopic cylinders arranged at the front end of the base, and the front end of the base is fixed with a horizontally arranged support seat and a vertically arranged fixed seat, and is provided with a slider rail assembly for slidingly setting the clamp arm, and the fixed seat is located between the support seat and the slider rail assembly, and the telescopic cylinder is placed on the support seat and fixed on the fixed seat, and the output end of the telescopic cylinder is fixedly connected to the slider of the slider rail assembly. This technical solution uses a pair of telescopic cylinders as a driving mechanism, and realizes the automatic opening and closing operation of the clamp arm through the support seat and the fixed seat arranged at the front end of the base, and the slider rail assembly, and the fixed seat is located between the support seat and the slider rail assembly, and the telescopic cylinder is placed on the support seat and fixed on the fixed seat. This design provides a stable fixing platform for the cylinder, ensures that the cylinder can accurately drive the slider to move, and prevents the problem of unstable clamping force or reduced clamping accuracy caused by cylinder movement, thereby improving the reliability and accuracy of the clamping operation.

[0009] As an improvement, a synchronization mechanism is provided between a pair of clamping arms, and the synchronization mechanism includes a bearing, a rotating block and a pair of connecting rods. The bearing is fixedly arranged at the rear end of the base, the rotating block is rotatably arranged on the bearing and is connected to the slider of the slider rail assembly through the connecting rod, and pins are symmetrically arranged at both ends of the rotating block. A connecting shaft is fixedly arranged on the slider of the slider rail assembly, and a clearance groove running through the front and back is provided on the base. The connecting shaft extends into the rear end of the base through the clearance groove, and one end of the connecting rod is rotationally connected to the pin, and the other end of the connecting rod is rotationally connected to the connecting shaft. This technical solution adds a synchronization mechanism on the original basis, and realizes the synchronous movement of the two clamping arms through the bearing, rotating block and connecting rod arranged at the rear end of the base and connected to the slider of the slider rail assembly through the clearance groove. The design of the synchronization mechanism not only improves the synchronization and coordination of the clamping action, but also reduces the vibration and noise during the clamping process, and improves the stability and reliability of the clamping operation.

[0010] As an improvement, a pair of guide holes are provided at intervals at the upper and lower front ends of the fixed frame, a through hole is provided on the fixed frame between the pair of guide holes, a guide column is provided between the fixed frame and the vertical plate, the front end of the guide column is fixedly connected to the vertical plate, the rear end of the guide column is slidingly set in the guide holes with front and rear limits, the push cylinder is fixedly set at the rear end of the fixed frame and is located between the pair of telescopic cylinders, and the output end of the push cylinder is inserted into the through hole and fixedly connected to the vertical plate. This technical solution realizes the stable forward and backward movement of the vertical plate by arranging guide holes and through holes on the fixed frame and utilizing guide columns, push cylinders and telescopic cylinders. This structural design effectively enhances the stability of the vertical plate when it is driven by the push cylinder to move forward and backward, so that the top block on the vertical plate can more stably support the rear end of the outer wall of the transmission housing, thereby improving the stability and reliability during the clamping process and avoiding the problem of reduced clamping accuracy or clamping failure caused by unstable movement of the vertical plate. At the same time, the structural design in which the push cylinder is located between a pair of telescopic cylinders can make the output forces of the three on the same horizontal plane, thereby making the forces acting on both sides of the transmission housing and the upper and lower ends of the rear end of the transmission housing more balanced, which is beneficial to the stable clamping of the transmission housing and also makes the overall structure of the transmission housing clamping device more compact.

[0011] As an improvement, a first bolt and a second bolt are provided between the vertical plate and the top block for adjusting the spacing between the two. A socket and a threaded hole are provided on the vertical plate that pass through the vertical plate from front to back. The first bolt is inserted into the socket from the rear end of the vertical plate and is threadedly connected to the rear end of the top block. The rear end of the second bolt is threadedly connected in the threaded hole, and the front end of the second bolt is against the rear end of the top block. When in use, the first bolt pulls the top block backwards and the second bolt pushes the top block forwards. The two bolts pull and push to firmly fix the top block on the front end of the vertical plate, so that the top block can firmly support the rear end of the transmission housing. The first bolt is controlled to be screwed in and out on the top block while the second bolt is controlled to be screwed in and out in the threaded hole of the vertical plate accordingly, so that the spacing between the vertical plate and the top block can be adjusted. In this way, when used on transmission housings of different specifications, the spacing between the top block and the vertical plate at different positions on the vertical plate can be adjusted by the first bolt and the second bolt, so that the different diameters of the upper and lower ends of the transmission housing can be well adapted, so that the top block 34 can always be stably clamped at the rear end of the outer wall of the transmission housing, effectively solving the problem of unstable clamping caused by differences in housing sizes, and improving the adaptability and accuracy of the clamping process.

[0012] As an improvement, a clamp block is fixedly provided at the front end of the clamp arm, and a clamping groove is formed between the clamp block and the latch pin for clamping on the convex ribs on both sides of the outer wall of the transmission housing. After applying this structure, the latch pin on the clamp arm is inserted into the process holes on both sides of the housing to achieve positioning, and the clamping groove formed between the clamp block and the latch pin further locks the clamp arm and prevents the clamped transmission housing from rotating around the latch pin. The clamping groove is clamped on the convex rib of the outer wall of the housing to ensure that the clamp arm will not loosen or fall off under vibration and impact, effectively preventing the clamp arm from sliding or deflecting, thereby improving the stability, reliability and accuracy of the clamping process and improving efficiency.

[0013] As an improvement, a bracket is fixed at the rear end of the base, and a lifting seat and a sponge suction device for sucking the partition are provided below the bracket. The lifting seat is set on the bracket and moves up and down through a pair of lifting cylinders, and the sponge suction device is fixed at the bottom of the lifting seat. This improvement scheme can effectively suck the partitions between the transmission housings, realize automatic removal of the partitions, improve production efficiency and automation, and make the production line operation continuous. At the same time, the setting of the lifting cylinder avoids the interference of the sponge suction device with the surrounding environment when sucking the partition.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, in the utility model, the transmission housing clamping device comprises a base 1 and a clamping mechanism 2 for clamping the two sides of the outer wall of the transmission housing, the clamping mechanism 2 comprises a pair of clamping arms 21 arranged at the front end of the base 1 and a driving mechanism arranged on the base 1 for driving the pair of clamping arms 21 to open and close left and right, and an ejection mechanism 3 is arranged between the pair of clamping arms 21, and the ejection mechanism 3 comprises a fixed frame 31 fixedly arranged at the front end of the base 1, a push cylinder 32 with the output end facing forward arranged on the fixed frame 31, a vertical plate 33 fixedly arranged at the output end of the push cylinder 32, and at least two ejection blocks 34 arranged at the front end of the vertical plate 33 at intervals up and down, and the front end of the ejection block 34 is fixedly provided with a profiling block 340 adapted to the shape of the rear end of the outer wall of the transmission housing, and the front end of the clamping arm 21 is fixedly provided with a latch 211 for inserting into the process holes on both sides of the outer wall of the transmission housing. When in use, the base 1 of the utility model is mounted on a mechanical arm and used in conjunction with other equipment in the automated production line.

[0025] In view of the problem that the prior art cannot effectively clamp the transmission housing, the utility model solves the problems of difficult and loose clamping by providing a pair of clamping arms 21 and an ejection mechanism 3. When in use, the latch 211 on the clamping arm 21 can be inserted into the process holes on both sides of the housing, and the ejection mechanism 3 fits tightly to the rear end of the outer wall of the housing through a plurality of ejection blocks 34 and a contoured block 340, providing necessary supporting force to ensure that the housing will not rotate or fall off during the clamping process. At the same time, the utility model uses a driving mechanism to control the left and right opening and closing of the clamping arm 21, and the push cylinder 32 controls the forward and backward movement of the ejection block 34, thereby realizing automatic clamping, avoiding the time-consuming and labor-intensive problems caused by manual lifting of the housing, improving production efficiency, and being able to better cooperate with the automated production line.

[0026] like Figure 2 and Figure 5 As shown, the driving mechanism is a pair of telescopic cylinders 22 arranged at the front end of the base 1, and a horizontally arranged support seat 11 and a vertically arranged fixed seat 12 are fixed to the front end of the base 1, and a slider rail assembly 13 for slidingly setting the clamping arm 21 is provided, and the fixed seat 12 is located between the support seat 11 and the slider rail assembly 13, and the telescopic cylinder 22 is placed on the support seat 11 and fixed on the fixed seat 12, and the output end of the telescopic cylinder 22 is fixedly connected to the slider of the slider rail assembly 13. This technical solution uses a pair of telescopic cylinders 22 as a driving mechanism, and realizes the automatic opening and closing operation of the clamping arm 21 through the support seat 11 and the fixed seat 12 and the slider rail assembly 13 arranged at the front end of the base 1. The fixed seat 12 is located between the support seat 11 and the slider rail assembly 13, and the telescopic cylinder 22 is placed on the support seat 11 and fixed on the fixed seat 12. This design provides a stable fixed platform for the cylinder, ensuring that the cylinder can accurately drive the slider to move, and preventing the problem of unstable clamping force or reduced clamping accuracy caused by cylinder movement, thereby improving the reliability and accuracy of the clamping operation.

[0027] like Figure 4 As shown, a synchronization mechanism 4 is provided between a pair of clamp arms 21, and the synchronization mechanism 4 includes a bearing 41, a rotating block 42 and a pair of connecting rods 43. The bearing 41 is fixedly arranged at the rear end of the base 1, and the rotating block 42 is rotatably arranged on the bearing 41 and is transmission-connected to the slider of the slider rail assembly 13 through the connecting rod 43. Pins 421 are symmetrically provided at both ends of the rotating block 42, and a connecting shaft 131 is fixedly provided on the slider of the slider rail assembly 13. An air avoidance groove 14 running through the front and rear is opened on the base 1, and the connecting shaft 131 extends into the rear end of the base 1 through the air avoidance groove 14. One end of the connecting rod 43 is rotatably connected to the pin 421, and the other end of the connecting rod 43 is rotatably connected to the connecting shaft 131. This technical solution adds a synchronization mechanism 4 on the original basis, and realizes the synchronous movement of the two clamping arms 21 through the bearing 41, the rotating block 42 and the connecting rod 43 which are arranged at the rear end of the base 1 and connected to the slider of the slider rail assembly 13 through the air avoidance groove 14. The design of the synchronization mechanism 4 not only improves the synchronization and coordination of the clamping action, but also reduces the vibration and noise during the clamping process, thereby improving the stability and reliability of the clamping operation.

[0028] like Figure 5 and Figure 6As shown, a pair of guide holes 311 are spaced apart at the upper and lower front ends of the fixed frame 31, a through hole 312 is provided on the fixed frame 31 between the pair of guide holes 311, a guide column 330 is provided between the fixed frame 31 and the vertical plate 33, the front end of the guide column 330 is fixedly connected to the vertical plate 33, the rear end of the guide column 330 is slidingly set in the guide hole 311 with front and rear limits, the push cylinder 32 is fixedly set at the rear end of the fixed frame 31 and is located between the pair of telescopic cylinders 22, and the output end of the push cylinder 32 is inserted into the through hole 312 and fixedly connected to the vertical plate 33. The technical solution realizes stable forward and backward movement of the vertical plate 33 by setting a guide hole 311 and a through hole 312 on the fixed frame 31, and using the guide column 330, the push cylinder 32 and the telescopic cylinder 22. This structural design effectively enhances the stability of the vertical plate 33 when it is driven by the push cylinder 32 to move forward and backward, so that the top block 34 on the vertical plate 33 can more stably support the rear end of the outer wall of the transmission housing, thereby improving the stability and reliability of the clamping process, and avoiding the problem of reduced clamping accuracy or clamping failure caused by unstable movement of the vertical plate 33. At the same time, the structural design of the push cylinder 32 being located between a pair of telescopic cylinders 22 can make the output forces of the three on the same horizontal plane, thereby making the forces acting on both sides of the transmission housing and the upper and lower ends of the rear end of the transmission housing more balanced, which is conducive to the stable clamping of the transmission housing and also makes the overall structure of the transmission housing clamping device more compact.

[0029] like Figure 6 As shown, a first bolt 341 and a second bolt 342 are provided between the vertical plate 33 and the top block 34 for adjusting the spacing between the two. The vertical plate 33 is provided with a plug hole 331 and a threaded hole 332 that penetrate the vertical plate 33 from front to back. The first bolt 341 is inserted into the plug hole 331 from the rear end of the vertical plate 33 and is threadedly connected to the rear end of the top block 34. The rear end of the second bolt 342 is threadedly connected in the threaded hole 332, and the front end of the second bolt 342 is against the rear end of the top block 34. When in use, the first bolt 341 pulls the top block 34 backward and the second bolt 342 pushes the top block 34 forward. The two bolts pull and push to firmly fix the top block 34 to the front end of the vertical plate 33, so that the top block 34 can be firmly supported against the rear end of the transmission housing. The first bolt 341 is controlled to be screwed in and out on the top block 34, and the second bolt 342 is controlled to be screwed in and out in the threaded hole 332 of the vertical plate 33 accordingly, so that the spacing between the vertical plate 33 and the top block 34 can be adjusted. In this way, when used on transmission housings of different specifications, the spacing between the top block 34 and the vertical plate 33 at different positions on the vertical plate 33 can be adjusted by the first bolt 341 and the second bolt 342, so that the different diameters of the upper and lower ends of the transmission housing can be well adapted, so that the top block 34 can always be stably clamped at the rear end of the outer wall of the transmission housing, effectively solving the problem of unstable clamping caused by differences in housing sizes, and improving the adaptability and accuracy of the clamping process.

After the structure is applied, the latch pin 211 on the clamp arm 21 is inserted into the process holes on both sides of the housing to achieve positioning, and the clamping groove 210 formed between the clamp block 212 and the latch pin 211 further locks the clamp arm 21 and prevents the clamped transmission housing from rotating around the latch pin 211. The clamping groove 210 is clamped on the convex rib of the outer wall of the housing to ensure that the clamp arm 21 will not loosen or fall off under vibration and impact, effectively preventing the clamp arm 21 from sliding or deflecting, thereby improving the stability, reliability and accuracy of the clamping process and improving efficiency.

[0031] like Figure 7 As shown, on the basis of the original technical solution, in order to realize the layer-by-layer picking of the transmission housings separated and stacked with partitions, a bracket 5 is fixedly provided at the rear end of the base 1, and a lifting seat 51 and a sponge suction device 52 for sucking the partitions are provided below the bracket 5. The lifting seat 51 is arranged on the bracket 5 to move up and down through a pair of lifting cylinders 53, and the sponge suction device 52 is fixedly arranged at the bottom of the lifting seat 51. This improved solution can effectively suck the partitions between the transmission housings, realize the automatic removal of the partitions, improve the production efficiency and automation, and make the production line operation continuous. At the same time, the setting of the lifting cylinder 53 avoids the interference of the sponge suction device 52 with the surrounding environment when sucking the partitions.

[0032] Although the disclosure is disclosed as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the utility model.
