[0001] The present application relates to the technical field of piston processing equipment, and particularly relates to a piston BOOT pre-assembly device. Background Art

[0002] As Figure 1 , there is a piston for a brake caliper to be processed, which includes a piston body and a BOOT (sealing member) sleeved on the piston body. An embedding groove for the BOOT to be embedded is provided on the piston body. And a metal support member with a certain elasticity is arranged inside the BOOT to ensure the tight connection with the piston body and at the same time ensure its sealing effect.

[0003] The above-mentioned BOOT assembly process is usually manual assembly. However, due to the hardness of the BOOT itself, it is difficult for personnel to assemble, resulting in the problems of low assembly efficiency. Utility Model Content

[0004] In order to solve the above technical problems, the present application provides a piston BOOT pre-assembly device, which has the advantages of being able to automatically assemble the BOOT, thus saving human resources and improving production efficiency.

[0005] To achieve the above object, the technical solution of the present utility model is as follows:

[0010] Among them, the BOOT pressing mechanism includes a lower pressing plate, several clamping jaws are hinged on the lower pressing plate, an elastic member for making several clamping jaws close to each other is arranged between several clamping jaws, and a lower pressing driving member for driving the lower pressing plate to move downward.

[0011] To implement the above technical solution, that is, after placing the piston on the assembly table, inserting the guide sleeve on the top of the piston, manually placing the BOOT on the guide sleeve, and then driving the BOOT to be gradually pressed down along the guide sleeve by the BOOT pressing mechanism. At this time, the BOOT is gradually expanded due to the conical guide surface, so that the BOOT can be smoothly pressed down onto the piston and then gradually pressed into the embedding groove to complete the assembly of the BOOT. That is, several jaws are tightly pressed against the conical guide surface under the action of the elastic member, so that the multiple jaws can normally press against the inner ring root of the BOOT, ensuring that the BOOT can be normally pressed and expanded to ensure the smoothness of the assembly.

[0012] As a preferred solution of the present application, the pressing driving member includes a pressing frame provided on the bracket, a pressing telescopic cylinder is provided on the pressing frame, and the telescopic rod of the pressing telescopic cylinder is connected to the lower pressing plate.

[0014] As a preferred solution of the present application, the jaw includes a connecting rod hinged to the lower pressing plate, and an arc-shaped pressing plate is provided at the bottom of the connecting rod.

[0015] Implementing the above technical solution enables the arc-shaped pressing plate to rotate around the lower pressing plate following the connecting rod, and at the same time, the arc-shaped plate can ensure its contact area with the BOOT, thus ensuring that the BOOT can be transported and moved downward.

[0016] As a preferred solution of the present application, a transfer table for placing the guide sleeve is further provided on the bracket, and an automatic feeding component for taking and placing the guide sleeve back and forth between the assembly table and the transfer table is provided on the bracket.

[0017] As a preferred solution of the present application, the automatic feeding component includes a thumb cylinder, clamping plates for clamping the guide sleeve are provided on the two telescopic rods of the thumb cylinder, and a feeding driving member for driving the thumb cylinder to move horizontally up and down.

[0018] Implementing the above technical solution, that is, driving the thumb cylinder to move above the assembly table corresponding to the guide sleeve by the feeding driving member, the thumb cylinder drives the clamping plates to close and clamp the guide sleeve, and then the feeding driving member drives the guide sleeve to move to the transfer table, and then the thumb cylinder releases, so that the guide sleeve is placed on the transfer table; when it is necessary to automatically insert the guide sleeve into the piston, the thumb cylinder clamps the guide sleeve, and then the feeding driving member drives the thumb cylinder and the guide sleeve clamped by the thumb cylinder to be inserted into the piston, thus achieving the effect of automatic feeding.

[0019] As a preferred embodiment of the present application, the feeding driving member includes a vertical cylinder, a vertical bearing plate is arranged on the telescopic rod of the vertical cylinder, a horizontal cylinder is arranged on the vertical bearing plate, a horizontal bearing plate is arranged on the telescopic rod of the horizontal cylinder, and the thumb cylinder is arranged on the horizontal bearing plate.

[0021] To achieve the above technical solution, when the pressing plate moves upward, the contact rod continues to press the guide sleeve under the action of the contact spring to prevent the guide sleeve from being driven upward by the clamping jaws.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. After placing the piston on the assembly table, inserting the guide sleeve on the top of the piston, manually placing the BOOT on the guide sleeve, and then driving the BOOT to be gradually pressed down along the guide sleeve by the BOOT pressing mechanism. At this time, the BOOT is gradually expanded due to the conical guide surface, so that the BOOT can be smoothly pressed onto the piston and then gradually pressed into the embedding groove to complete the assembly of the BOOT.

[0024] 2. That is, by driving the thumb cylinder to move above the assembly table and corresponding to the guide sleeve through the feeding driving member, the thumb cylinder drives the clamping plates to clamp the guide sleeve together. Then, the feeding driving member drives the guide sleeve to move to the transfer table, and the thumb cylinder is loosened to place the guide sleeve on the transfer table. When it is necessary to automatically insert the guide sleeve into the piston, the thumb cylinder clamps the guide sleeve, and then the feeding driving member drives the thumb cylinder and the guide sleeve clamped by the thumb cylinder to be inserted into the piston, thereby achieving the effect of automatic feeding.

Detailed implementation manners

[0032] The following further elaborates on the present application in conjunction with the attached Figures 1-5 drawings.

[0033] An embodiment of the present application discloses a piston BOOT pre-assembly device. Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the piston BOOT 8 pre-assembly device includes a bracket 1; an assembly table 2 for placing and positioning the piston; a guide sleeve 3 detachably inserted on the piston body 7, and a conical guide surface 31 is provided on the outer wall of the guide sleeve 3; a BOOT pressing-down mechanism 4 for pressing the BOOT 8 from the guide sleeve 3 onto the embedding groove 9 on the piston. That is, after placing the piston on the assembly table and inserting the guide sleeve 3 on the top of the piston, manually placing the BOOT 8 on the guide sleeve 3, and then driving the BOOT 8 to be gradually pressed down along the guide sleeve 3 by the BOOT pressing-down mechanism 4. At this time, the BOOT 8 is gradually expanded due to the conical guide surface 31, so that the BOOT 8 can be smoothly pressed onto the piston and then gradually pressed into the embedding groove 9 to complete the assembly of the BOOT 8.

[0034] The BOOT pressing-down mechanism 4 includes a lower pressing plate 41. A number of clamping jaws 42 are hinged on the lower pressing plate 41. An elastic member for making the clamping jaws 42 close to each other and a pressing-down driving member 43 for driving the lower pressing plate 41 to move downward are arranged between the clamping jaws 42. That is, the clamping jaws 42 are pressed and attached to the conical guiding surface 31 under the action of the elastic member, so that the plurality of clamping jaws 42 can normally press on the inner ring root of the BOOT 8, ensuring that the BOOT 8 can be normally pressed and expanded to ensure the smoothness of assembly. The elastic member includes positioning pins 44 inserted through the clamping jaws 42. Springs are arranged between adjacent positioning pins 44, so that the clamping jaws 42 can close to each other under the action of the springs and move downward along with the guiding sleeve 3 and the piston. The clamping jaw 42 includes a connecting rod 421 hinged to the lower pressing plate 41. An arc-shaped pressing plate 422 is arranged at the bottom of the connecting rod 421. Thus, the arc-shaped pressing plate 422 can rotate around the lower pressing plate 41 following the connecting rod 421, and at the same time, the arc-shaped plate can ensure its contact area with the BOOT 8, ensuring that the BOOT 8 can be transported and moved downward.

[0035] The pressing-down driving member 43 includes a pressing-down frame 431 arranged on the bracket 1. A pressing-down telescopic cylinder 432 is arranged on the pressing-down frame 431. The telescopic rod of the pressing-down telescopic cylinder 432 is connected to the lower pressing plate 41. That is, the pressing-down telescopic cylinder 432 can drive the lower pressing plate 41 to move up and down, so as to achieve the effect of assembling the BOOT 8. Guide rods 433 are arranged on the lower pressing plate 41, and guide sleeves 434 for the guide rods 433 to slide are arranged on the pressing-down frame 431, so that the lower pressing plate 41 can move up and down evenly under the restriction of the guide rods 433 and the guide sleeves 434. After the assembly is completed, the pressing-down telescopic cylinder 432 drives the clamping jaws 42 to move upward, so that the guiding sleeve 3 moves upward to wait for the operator to take the material. Because of the action of the elastic member, the clamping jaws 42 will clamp the piston or the guiding sleeve 3 again, resulting in the situation that the piston and the guiding sleeve 3 move upward following the clamping jaws 42. Therefore, an abutting plate 435 is arranged on the guide rod 433. An abutting rod 436 is inserted through the abutting plate 435. The abutting rod 436 extends into the clamping jaws 42. An abutting ring 437 is arranged on the abutting rod 436. An abutting spring 438 is arranged between the abutting ring 437 and the abutting plate 435. That is, when the abutting rod 436 moves downward following the lower pressing plate 41, the abutting rod 436 abuts on the guiding sleeve 3 to ensure the stability of the guiding sleeve 3 and compress the abutting spring 438 synchronously. When the lower pressing plate 41 moves upward, the abutting rod 436 continues to press the guiding sleeve 3 under the action of the abutting spring 438 to prevent the guiding sleeve 3 from being driven upward by the clamping jaws 42.

[0036] After the assembly is completed, it is necessary to manually take out the guiding sleeve 3, resulting in low processing efficiency. Therefore, a transfer table 5 for placing the guiding sleeve 3 is further arranged on the bracket 1, and an automatic loading and unloading component 6 for taking and placing the guiding sleeve 3 back and forth between the assembly table 2 and the transfer table 5 is arranged on the bracket 1.

[0037] Refer toFigure 2 , Figure 3 , Figure 4 and Figure 5 , the automatic feeding assembly 6 includes a thumb cylinder 61. On the two telescopic rods of the thumb cylinder 61, there are clamping plates 62 for clamping the guide sleeve 3, and a feeding drive member for driving the thumb cylinder 61 to move horizontally up and down. That is, after the feeding drive member drives the thumb cylinder 61 to move above the assembly table 2 and correspond to the guide sleeve 3, the thumb cylinder 61 drives the clamping plates 62 to close and clamp the guide sleeve 3. Then, after the feeding drive member drives the guide sleeve 3 to move to the transfer table 5, the thumb cylinder 61 releases, so that the guide sleeve 3 is placed on the transfer table 5. When it is necessary to automatically insert the guide sleeve 3 onto the piston, after the thumb cylinder 61 clamps the guide sleeve 3, the feeding drive member drives the thumb cylinder 61 and the guide sleeve 3 clamped by the thumb cylinder 61 to be inserted into the piston, thus achieving the effect of automatic feeding.

[0038] The feeding drive member includes a vertical cylinder 63 arranged thereon. On the telescopic rod of the vertical cylinder 63, there is a vertical bearing plate 64. On the vertical bearing plate 64, there is a horizontal cylinder 65. On the telescopic rod of the horizontal cylinder 65, there is a horizontal bearing plate 66. The thumb cylinder 61 is arranged on the horizontal bearing plate 66. That is, when the vertical cylinder 63 drives the horizontal cylinder 65 to move to the relative height with the guide sleeve 3, and the horizontal cylinder 65 drives the clamping plates 62 on the thumb cylinder 61 to move to both sides of the guide sleeve 3, the thumb cylinder 61 drives the two clamping plates 62 to close to clamp the guide sleeve 3. Then, the vertical cylinder 63 and the horizontal cylinder drive the guide sleeve 3 to move and be transported to the transfer table 5. Similarly, the effect of automatically inserting the guide sleeve 3 on the transfer table 5 onto the piston can be achieved.

[0039] The implementation principle of a piston BOOT pre - installation device in an embodiment of the present application is as follows: 1. After placing the piston on the assembly table, inserting the guide sleeve 3 on the top of the piston, and manually placing the BOOT 8 on the guide sleeve 3, the BOOT pressing mechanism 4 drives the BOOT 8 to be gradually pressed down along the guide sleeve 3. At this time, the BOOT 8 is gradually expanded due to the conical guide surface 31, so that the BOOT 8 can be smoothly pressed onto the piston and then gradually pressed into the embedding groove 9 to complete the assembly of the BOOT 8. After the feeding drive member drives the thumb cylinder 61 to move above the assembly table 2 and correspond to the guide sleeve 3, the thumb cylinder 61 drives the clamping plates 62 to close and clamp the guide sleeve 3. Then, after the feeding drive member drives the guide sleeve 3 to move to the transfer table 5, the thumb cylinder 61 releases, so that the guide sleeve 3 is placed on the transfer table 5; when it is necessary to automatically insert the guide sleeve 3 onto the piston, after the thumb cylinder 61 clamps the guide sleeve 3, the feeding drive member drives the thumb cylinder 61 and the guide sleeve 3 clamped by the thumb cylinder 61 to be inserted into the piston, thus achieving the effect of automatic feeding.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
