Description

Technical Field

[0001] The present invention relates to the technical field of automotive part processing, and specifically to a master cylinder piston for a wire-controlled braking system of an automobile and a processing device therefor. Background Art

[0002] In a traditional vacuum booster, the brake pedal is connected to a valve rod, and the ball head at the end of the valve rod is connected to an air valve seat that controls the opening and closing of an atmospheric valve port. The air valve seat then transmits the input force to the master cylinder piston through a set of force transmission mechanisms to establish hydraulic pressure in the master cylinder.

[0003] The existing master cylinder piston uses a buffer pad assembly method to achieve buffering, shock absorption, and noise reduction. The piston buffer pad needs to be designed and processed separately, resulting in high costs. Moreover, the piston buffer pad is installed inside the cylinder block. It is necessary to completely close the opening of the buffer pad and then place it into the cylinder block, and then rely on the resilience of the metal skeleton to ensure that the product is assembled in place. The installation difficulty is high, and the resilience requirement for the metal skeleton is very high. At the same time, the price of high-resilience metal is expensive, and the use and replacement maintenance costs are high. Summary of the Invention

[0036] The technical solutions of the present invention will be further described in detail below in conjunction with specific embodiments.

An adhesive is applied to the snap-fitting part between the rubber ring 03 and the groove 02.

[0038] As Figure 2 、 Figure 3 shown, based on the above processing device for a master cylinder piston of an automotive electronic brake system, it includes a conveyor belt 1 and a conveyor belt 2. The master cylinder piston bodies 01 are evenly conveyed on the conveyor belt 1. The master cylinder piston bodies 01 are placed on the placing seats. An extraction mechanism 3 is arranged on the conveyor belt 1. A combined processing mechanism 4 is arranged between the conveyor belt 1 and the conveyor belt 2. A blanking mechanism 5 is arranged on the conveyor belt 2.

[0039] As Figure 4 、 Figure 6As shown, an installation frame one 10 is provided at the edge of the conveyor belt one 1. The extraction mechanism 3 includes a fixed frame one 30 provided on the installation frame one 10. A moving frame one 31 is horizontally connected to the end of the fixed frame one 30. A lifting frame one 34 is vertically installed on the moving frame one 31. A grasping assembly 36 is provided at the bottom end of the lifting frame one 34. The grasping assembly 36 cooperates with the tail end of the main cylinder piston body 01. A horizontal plate 37 is provided on the lifting frame one 34. A glue brushing assembly is provided on the horizontal plate 37. The combined processing mechanism 4 includes a rotating disk 44. A plurality of lower molds 47 and upper molds 48 are annularly distributed on the surface of the rotating disk 44. The extraction mechanism 3 carries the main cylinder piston body 01 brushed with glue and cooperates with the upper mold 48 and the lower mold 47. The upper mold 48 is connected with an injection pipe 410 and a material barrel 412.

[0040] Specifically, the main cylinder piston body 01 is conveyed through the conveyor belt one 1 and grasped by the extraction mechanism 3 provided on the conveyor belt one 1. The grasped main cylinder piston body 01 moves to the edge of the combined processing mechanism 4 and cooperates with the upper mold 48 and the lower mold 47 placed on the rotating disk 44. An injection pipe 410 and a material cylinder are combined to inject plastic into the upper mold 48 and the lower mold 47 to form a rubber ring 03. After the rubber ring 03 solidifies, it is directly clamped in the groove 02 at the end of the main cylinder piston, eliminating the manual assembly operation of the rubber ring 03 and the groove 02 at the end of the main cylinder piston body 01. At the same time, the matching degree between the rubber ring 03 and the end of the main cylinder piston body 01 is improved, and the sealing effect is enhanced.

[0041] Furthermore, as Figure 4 、 Figure 5 shown, the moving frame one 31 is inserted into the end of the fixed frame one 30 through a plugging rod one 32. A horizontal air cylinder one 33 is provided between the moving frame one 31 and the fixed frame one 30. A vertical air cylinder one 35 is provided between the lifting frame one 34 and the moving frame one 31. The grasping assembly 36 includes a telescopic air cylinder one 360 connected to the end of the lifting frame one 34. The telescopic air cylinder one 360 is connected with a telescopic column 361 and a moving disk 362. Matching rods 363 are annularly distributed around the telescopic column 361 on the lifting frame one 34. The matching rods 363 are annularly and obliquely inserted into the moving disk 362. A contact block 364 is provided at the end of the matching rod 363.

[0042] Specifically, the telescopic cylinder 360 in the grasping component 36 drives the moving disk 362 to move horizontally, controlling the annularly distributed mating rods 363 and the contact blocks 364 at the ends to open within the inner ring of the main cylinder piston body 01, thereby achieving the grasping of the main cylinder piston body 01. The horizontal cylinder 33 and the vertical cylinder 35 drive the grasping component 36 and the main cylinder piston body 01 to move to the edge of the combined processing mechanism 4, so as to inject the rubber ring 03 onto the edge of the main cylinder piston body 01.

[0043] Further, as Figure 4 shown, the glue brushing component includes a telescopic motor 38 arranged on the horizontal plate 37. The telescopic motor 38 is connected with a curved pressing plate 39. A driving roller 310 is rotatably installed on the curved pressing plate 39. The driving roller 310 is connected with a rotating motor 311. The rotating motor 311 is fixedly installed on the curved pressing plate 39. The end of the horizontal plate 37 is provided with a telescopic motor 312. The end of the telescopic motor 312 is installed with a brush head 313 in a lifting manner.

[0044] Specifically, the telescopic motor 38 drives the curved pressing plate 39 to press on the upper side of the main cylinder piston body 01. Combining with the driving roller 310 driving the main cylinder piston body 01 to rotate between the curved pressing plate 39 and the placing seat, the brush head 313 is controlled to contact the end of the main cylinder piston body 01, thereby performing the glue brushing operation.

[0045] Further, as Figure 6 、 Figure 7 shown, the combined processing mechanism 4 further includes a fixedly installed bottom plate 40. A gear disk 41 is rotatably installed on the bottom plate 40. A sleeve 43 is arranged between the gear disk 41 and the rotating disk 44. A central column 45 is fixedly installed on the bottom plate 40. The gear disk 41 and the rotating disk 44 are sleeved on the central column 45 through the sleeve 43. A driving gear 42 is rotatably installed on the bottom plate 40. The driving gear 42 meshes with the gear disk 41. The driving gear 42 is connected with a power motor 420. Telescopic cylinders 46 are annularly distributed at the positions corresponding to the lower die 47 on the rotating disk 44. The telescopic cylinders 46 are connected with the lower die 47.

The annular pipe 411 is connected with an injection pipe 410. A delivery pump 413 is arranged between the annular pipe 411 and the material bucket 412.

[0046] Specifically, the driving motor 420 drives the driving gear 42 and the gear disk 41 to mesh with each other, controlling the upper rotating disk 44 to rotate, thereby realizing multi-station injection molding processing, effectively improving the injection molding efficiency of the rubber ring 03 at the end of the main cylinder piston body 01. At the same time, the multi-station mode can utilize the interval time of feeding and discharging to perform high-temperature vulcanization treatment on the injected rubber ring 03, improving the matching effect between the rubber ring 03 and the end of the main cylinder piston body 01 and the injection molding quality of the rubber ring 03.

[0047] More specifically, the telescopic cylinder two 46 controls the upper mold 48 and the lower mold 47 to move integrally along the radial direction of the rotating disk 44, so as to facilitate the cooperation between the upper mold 48 and the lower mold 47 and the end of the main cylinder piston body 01 extracted by the extraction mechanism 3. After the extraction mechanism 3 releases the grasping of the main cylinder piston body 01 after injection molding, the rotating disk 44 combines with the upper mold 48 and the lower mold 47 to perform a transposition on the main cylinder piston body 01, thereby performing the injection molding operation on the next main cylinder piston body 01, and at the same time performing a discharging operation on the main cylinder piston body 01 that has completed the injection molding operation.

[0048] Further, as Figure 6 、 Figure 7 、 Figure 9 shown, a mold release agent cylinder 414 is fixedly arranged on the bottom plate 40, the mold release agent cylinder 414 is connected with a mating head 415, and the mating head 415 cooperates with the upper mold 48 and the lower mold 47.

[0049] Specifically, in order to facilitate the overall separation of the main cylinder piston body 01 and the rubber ring 03 from between the upper mold 48 and the lower mold 47 after injection molding, before injection molding, the mold release agent cylinder 414 and the mating head 415 cooperate with the upper mold 48 and the lower mold 47, and the mating head 415 sprays the mold release agent between the upper mold 48 and the lower mold 47. The upper mold 48 and the lower mold 47 are integrally controlled to cooperate with and disengage from the mating head 415 through the telescopic cylinder three.

A second fixing frame 50 is arranged on the second mounting frame 20. A second moving frame 51 is arranged at the end of the second fixing frame 50.

The third telescopic motor 56 is connected to an arc-shaped pressing plate 57. A fixing plate 58 is arranged at the top of the central column 45. A telescopic cutting knife 59 is arranged on the fixing plate 58.

[0051] Specifically, after the rubber ring 03 is injection-molded and vulcanized at high temperature, it is transferred to the blanking mechanism 5. The grasping assembly 36 on the second lifting frame 54 grabs the end of the main cylinder piston body 01. After controlling the main cylinder piston body 01 and the rubber plug as a whole to separate from the upper mold 48 and the lower mold 47, the main cylinder piston body 01 is pressed by the third telescopic motor 56 and the arc-shaped pressing plate 57. The injection gate part is cut off by the telescopic cutting knife 59 on the fixing plate 58.

[0052] Further, as Figure 11 、 Figure 12 、 Figure 13 、 Figure 14As shown in the figure, a groove processing mechanism 6 is also provided. The groove processing mechanism 6 includes a side frame 11 arranged at the edge of the first conveyor belt 1. Two groups of moving blocks 61 are slidably installed on the edge of the side frame 11. A bidirectional lead screw 60 is threadedly installed between the moving blocks 61. The bidirectional lead screw 60 is connected to a drive motor 62. A first guide post 65 is arranged at the upper end of the side frame 11. A first lifting block 64 is slidably installed between the first guide posts 65. A support rod 63 is rotatably installed between the moving block 61 and the first lifting block 64. A first clamping motor 66 is arranged on the first lifting block 64. The first clamping motor 66 is connected to a first chuck 67. A second guide post 611 is arranged on the first mounting frame 10. A second lifting block 610 is slidably installed between the second guide posts 611. A second clamping motor 612 is arranged on the second lifting block 610. The second clamping motor 612 is provided with a connecting curved rod 613. The connecting curved rod 613 is connected to a second rotating motor 614. The second rotating motor 614 is connected to a second chuck 615. A first top plate 616 is arranged on the first chuck 67. A lifting cutter head 618 is slidably installed on the first top plate 616. A distance adjusting motor 617 is arranged between the first top plate 616 and the lifting cutter head 618. A second top plate 619 is arranged on the second chuck 615. A locking column 620 is arranged on the second top plate 619. The locking column 620 cooperates with the side of the main cylinder piston body 01. A linkage rod 68 is arranged between the first lifting block 64 and the second lifting block 610.

[0053] Specifically, in order to improve the automation processing degree of the injection molding of the main cylinder piston body 01, the end groove 02 is processed first before the injection molding of the main cylinder piston body 01. The main cylinder piston body 01 conveyed on the first conveyor belt 1 is clamped under the drive of the first clamping motor 66 and the second clamping motor 612. The first lifting block 64 and the second lifting block 610 on the left and right sides are lifted by the drive motor 62 and the bidirectional lead screw, so as to lift the main cylinder piston body 01. The main cylinder piston body 01 is locked by the locking column 620. The position and depth of the cutter head are adjusted by the lifting cutter head 618 and the distance adjusting motor 617 to process the groove 02, so as to facilitate the subsequent clamping between the rubber ring 03 and the groove 02 during injection molding.

[0054] The usage method of the above processing device is as follows: When in use, first place the main cylinder piston body 01 in the placement seat of the first conveyor belt 1. The grooving mechanism 6 grabs the main cylinder piston and processes the groove 02 at the end. After the groove 02 is processed, the main cylinder piston body 01 is placed back on the placement seat of the first conveyor belt 1 and conveyed forward along the first conveyor belt 1. When the main cylinder piston body 01 is conveyed to the extraction mechanism 3, it is grabbed by the extraction mechanism 3 and sent to the edge of the combined processing mechanism 4, and then sent between the upper mold 48 and the lower mold 47 for injection molding operation. After the injection molding is completed and waiting for cooling, it rotates while carrying the main cylinder piston body 01 and the rubber ring 03 to perform the injection molding processing operation of the next main cylinder piston body 01. During the rotation process, the rubber ring 03 is vulcanized at high temperature at the same time. When it reaches the blanking mechanism 5, it is grabbed by the blanking mechanism 5 and separated from between the upper mold 48 and the lower mold 47. After cutting off the injection gate, it is placed on the second conveyor belt 2 to complete the processing operation of the rubber ring 03 and the main cylinder piston body 01.

[0055] The working principle of the embodiment of the present invention is: As Figures 1 - 14As shown in the figure, the main cylinder piston body 01 is conveyed by the first conveyor belt 1, and is grasped by the extraction mechanism 3 provided on the first conveyor belt 1. The grasped main cylinder piston body 01 is moved to the edge of the combined processing mechanism 4, and cooperates with the upper mold 48 and the lower mold 47 placed on the rotating disk 44. Combining the injection molding pipe 410 and the barrel, rubber is injected between the upper mold 48 and the lower mold 47 to form the rubber ring 03. After the rubber ring 03 solidifies, it is directly clamped in the groove 02 at the end of the main cylinder piston, eliminating the manual assembly operation of the rubber ring 03 and the groove 02 at the end of the main cylinder piston body 01. At the same time, the matching degree between the rubber ring 03 and the end of the main cylinder piston body 01 is improved, and the sealing effect is enhanced. The retractable cylinder 360 in the grasping assembly 36 drives the moving disk 362 to move horizontally, controlling the annularly distributed matching rods 363 and the contact blocks 364 at the ends to open inside the inner ring of the main cylinder piston body 01, thereby realizing the grasping of the main cylinder piston body 01. The horizontal cylinder 33 and the vertical cylinder 35 drive the grasping assembly 36 and the main cylinder piston body 01 to move to the edge of the combined processing mechanism 4, so as to inject the rubber ring 03 on the edge of the main cylinder piston body 01. The retractable cylinder 46 controls the overall movement of the upper mold 48 and the lower mold 47 along the radial direction of the rotating disk 44, so as to facilitate the cooperation between the upper mold 48 and the lower mold 47 and the end of the main cylinder piston body 01 extracted by the extraction mechanism 3. After the extraction mechanism 3 releases the grasping of the main cylinder piston body 01 after the injection molding is completed, the rotating disk 44 combines the upper mold 48 and the lower mold 47 to rotate the main cylinder piston body 01, so as to perform the injection molding operation of the next main cylinder piston body 01, and at the same time perform the blanking operation on the main cylinder piston body 01 that has completed the injection molding operation. In order to facilitate the overall separation of the main cylinder piston body 01 and the rubber ring 03 from between the upper mold 48 and the lower mold 47 after injection molding, before injection molding, the release agent cylinder 414 and the mating head 415 cooperate with the upper mold 48 and the lower mold 47, and the mating head 415 sprays the release agent between the upper mold 48 and the lower mold 47. The overall upper mold 48 and lower mold 47 are controlled to cooperate with and disengage from the mating head 415 through the retractable cylinder 3. After the rubber ring 03 is injection molded and vulcanized at high temperature, it is transferred to the blanking mechanism 5. The grasping assembly 36 on the lifting frame 54 grasps the end of the main cylinder piston body 01. After controlling the overall separation of the main cylinder piston body 01 and the rubber plug from the upper mold 48 and the lower mold 47, the main cylinder piston body 01 is pressed by the retractable motor 56 and the arc-shaped pressing plate 57. The injection molding gate part is cut off by the retractable cutting knife 59 on the fixing plate 58.
