[0002] In order to ensure that the outer diameter size and precision of the automobile brake shoe meet the design requirements, the outer diameter of the automobile brake shoe needs to be ground by a grinding rod before bonding or riveting the friction lining.

DETAILED DESCRIPTION

[0029] 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.

[0030] like Figure 1-10The outer circle adaptive grinding device of an automobile brake shoe is shown, which is used to produce an automobile brake shoe 5. The automobile brake shoe 5 is composed of an outer arc wall plate 51 and an inner support rib 52, including a working platform and a push-pushing and resisting mechanism 1 installed on the working platform, an in-place clamping mechanism 2, an adaptive adjustment mechanism 3, a deflection drive mechanism 4 and a grinding mechanism 6. The push-pushing and resisting mechanism 1 includes a first mounting frame 11, a first pushing assembly 12, a first resisting assembly 13 and a support plate 14. The support plate 14 is fixedly installed on the working platform. The automobile brake shoe 5 is arranged on the support plate 14. The first The mounting frame 11 is located on the side of the automobile brake shoe 5 close to the outer arc-shaped wall plate 51, the first pushing component 12 and the first resisting component 13 are both mounted on the first mounting frame 11, the in-place clamping mechanism 2 is arranged on the side of the automobile brake shoe 5 away from the pushing and resisting mechanism 1, the in-place clamping mechanism 2 includes a second pushing component 21, a third pushing component 22, a brake shoe clamping component 23 and an inner resisting component 24, the second pushing component 21 is horizontally arranged on the working platform, the third pushing component 22 and the brake shoe clamping component 23 are both arranged on the output end of the second pushing component 21, and the inner resisting component 24 is arranged on the inner side. The contact assembly 24 is arranged on the output end of the third pushing assembly 22, and the adaptive adjustment mechanism 3 includes a rotating central column 31, a sliding mounting frame 32, a rotating transmission frame 33, a rotating drive assembly 34, an adaptive adjustment assembly 35 and a supporting assembly 36. The rotating central column 31 is vertically mounted on the working platform, and the rotating transmission frame 33 is rotatably mounted on the rotating central column 31 through a bearing. The axis of the rotating central column 31 is coaxially arranged with the arc surface of the automobile brake shoe 5, and the sliding mounting frame 32 is horizontally slidably arranged on the rotating transmission frame 33. The rotating drive assembly 34 is mounted through a connecting frame. It is installed on the working platform and is connected to the rotating transmission frame 33, the adaptive adjustment component 35 is installed on the sliding mounting frame 32 and is connected to the rotating transmission frame 33, the support component 36 is installed on the rotating center column 31, and the grinding mechanism 6 includes a first lifting component 61, a grinding drive component 62 and a grinding roller 63. The first lifting component 61 is fixedly installed on the end of the sliding mounting frame 32 away from the rotating center column 31, the grinding drive component 62 is fixedly installed on the output end of the first lifting component 61, and the grinding roller 63 is vertically fixedly installed on the output end of the grinding drive component 62.

[0031] When the present invention is working, the automobile brake shoe 5 to be ground is loaded onto the support plate 14 through the loading and conveying device. At this time, one side of the outer arc-shaped wall plate 51 of the automobile brake shoe 5 faces the pushing and resisting mechanism 1, and one side of the inner supporting rib 52 faces the in-place clamping mechanism 2. The automobile brake shoe 5 is pushed toward the in-place clamping mechanism 2 through the output of the pushing and resisting mechanism 1. Under the joint action of the first resisting component 13 and the inner resisting component 24, the position of the automobile brake shoe 5 is corrected during the clamping process, so that the arc surface of the automobile brake shoe 5 is coaxial with the rotating center column 31. At this time, the angular deflection direction of the automobile brake shoe 5 is not accurate, and the clamping of the automobile brake shoe 5 is achieved through the deflection drive mechanism 4. The sliding mounting frame 32 is driven to rotate a certain angle by the rotating drive component 34, so that the automobile brake shoe 5 is centered as a whole, which is convenient for the subsequent grinding operation. After the deviation correction is completed, the brake shoe clamping component 23 in the clamping mechanism 2 is used to accurately clamp the inner support rib 52. After the positioning clamping is completed, the outer wall surface of the outer arc-shaped wall panel 51 is ground by the grinding mechanism 6. The grinding mechanism 6 is driven by the rotating drive component 34 to move along the arc surface of the outer arc-shaped wall panel 51 to realize the grinding process. When the product model changes, the self-adaptive adjustment component 35 can adaptively change the running trajectory of the deflection drive mechanism 4 and the grinding mechanism 6.

[0032] The present invention can automatically realize the correction and clamping functions of the automobile brake shoe 5, and automatically realize accurate grinding operations after the clamping is completed. When the specifications of the product change, the present invention can adaptively change the correction clamping position and the grinding arc, so as to adapt to the grinding requirements of automobile brake shoes 5 of different specifications, improve the adaptability and practicality of the equipment, and facilitate large-scale promotion.

[0033] The deflection driving mechanism 4 includes an inner side correction clamping assembly 41, a second lifting assembly 42 and a fourth pushing assembly 43. The fourth pushing assembly 43 is fixedly mounted in the middle of the sliding mounting frame 32. The second lifting assembly 42 is arranged on the output end of the fourth pushing assembly 43. The inner side correction clamping assembly 41 is fixedly mounted on the output end of the second lifting assembly 42. The inner side correction clamping assembly 41 includes a second clamping cylinder 411 and a second clamping plate 412. The second clamping cylinder 411 is vertically arranged. There are two second clamping plates 412 horizontally arranged. The two second clamping plates 412 are respectively arranged at the upper and lower ends of the inner supporting rib 52. The second clamping plate 412 located at the top is fixedly connected to the output end of the second lifting assembly 42. The second clamping plate 412 located at the bottom is fixedly connected to the output end of the second clamping cylinder 411.

[0034] The fourth pushing component 43 pushes the deflection drive mechanism 4 to the clamping station, and drives the deflection drive mechanism 4 to descend as a whole through the output of the second lifting component 42. First, the second clamping plate 412 located at the top is fitted with the surface of the inner supporting rib 52 at the top, and then the second clamping cylinder 411 outputs to move the second clamping plate 412 located at the bottom upward. The two second clamping plates 412 are brought close to each other to clamp the automobile brake shoe 5 located in the middle. Thereafter, the deflection sliding mounting frame 32 can be used to drive the deflection drive mechanism 4 installed on the sliding mounting frame 32 to deflect, thereby realizing the function of driving the automobile brake shoe 5 to deflect a certain angle.

[0035] The first resistance component 13 includes a central push plate 131, a resistance rod 132, a spring 133 and a first pressure sensor 134. The central push plate 131 is fixedly installed in the middle of the output end of the first push component 12. The resistance rod 132, the spring 133 and the first pressure sensor 134 are provided with at least two groups and are respectively located on both sides of the output end of the first push component 12. The resistance rod 132 is horizontally arranged. The resistance rod 132 can be slidably arranged on the output end of the first push component 12. The end of the resistance rod 132 points to the automobile brake shoe 5. The spring 133 is sleeved on the resistance rod 132. The first pressure sensor 134 is fixedly installed on the output end of the first push component 12. One end of the spring 133 is fixedly connected to the first pressure sensor 134, and the other end of the spring 133 is fixedly connected to the resistance rod 132.

[0036] When the first pushing component 12 is output, the first pushing component 12 drives the first resisting component 13 to move in the direction close to the automobile brake shoe 5, and the central pushing plate 131 and the resisting rod 132 in the first resisting component 13 resist against the outer wall of the outer arc-shaped wall plate 51. The central pushing plate 131 can resist against the center of the automobile brake shoe 5, and the resisting rod 132 can resist against the two ends of the automobile brake shoe 5. With the inner resisting function of the inner resisting component 24, the position of the automobile brake shoe 5 can be corrected, which is convenient for the subsequent clamping operation and ensures the clamping The holding accuracy is improved. The resistance rods 132 at both ends can detect whether the positions of the two ends of the automobile brake shoe 5 are aligned. The spring 133 provides elastic force for the resistance rod 132, so that the end of the resistance rod 132 is always in contact with the side wall of the outer arc-shaped wall panel 51. The first pressure sensor 134 is used to detect the resistance force of the resistance rod 132, so as to determine whether the two resistance rods 132 are in the same resistance position. When the two values ​​are equal, it means that the automobile brake shoe 5 is in a vertically stable state. At this time, it only needs to adjust the deflection angle of the automobile brake shoe 5 to achieve the precise clamping function.

[0037] A first rotating roller 135 is disposed on the central pushing plate 131 , a fixing ring 136 is fixedly disposed at the middle of the abutting rod 132 , and an abutting head 137 is disposed at one end of the abutting rod 132 close to the outer arc-shaped wall plate 51 .

[0038] The first roller 135 and the abutment head 137 ensure that after the center push plate 131 and the abutment rod 132 abut against the outer arc-shaped wall panel 51, the automobile brake shoe 5 can still be deflected under the drive of the deflection drive mechanism 4, thereby controlling the posture of the automobile brake shoe 5 and ensuring that the automobile brake shoe 5 is in the center of the clamping position during grinding, which is convenient for subsequent grinding operations.

[0039] The rotary drive assembly 34 includes a reduction motor 341, a rotating tooth 342 and a first driving tooth 343. The reduction motor 341 is fixedly mounted on the connecting frame of the working platform. The first driving tooth 343 is fixedly mounted on the output end of the reduction motor 341. The rotating tooth 342 is horizontally arranged. The rotating tooth 342 is coaxially arranged with the rotating center column 31. The rotating tooth 342 is fixedly connected to the rotating transmission frame 33, and the rotating tooth 342 is meshed with the first driving tooth 343.

[0040] When performing correction operations or grinding operations, the rotation drive component 34 works to drive the sliding mounting frame 32 to rotate, thereby driving the deflection drive mechanism 4 and the grinding mechanism 6 installed on the sliding mounting frame 32 to rotate synchronously, thereby realizing the correction or grinding work. The output of the reduction motor 341 drives the first drive tooth 343 to rotate. When the first drive tooth 343 rotates, it drives the rotating tooth 342 meshing with it to rotate. The rotating tooth 342 drives the rotating transmission frame 33 fixedly connected to it to rotate synchronously. The rotating transmission frame 33 drives the sliding mounting frame 32 connected to it to rotate synchronously, thereby realizing the rotation drive function.

[0041] The adaptive adjustment component 35 includes a rotation driver 351, a second driving tooth 352, a driven tooth 353, a threaded rod 354 and a threaded seat 355. The rotation driver 351 is fixedly mounted on the end of the sliding mounting frame 32 away from the automobile brake shoe 5. The second driving tooth 352 is fixedly mounted on the output end of the rotation driver 351. The threaded rod 354 is horizontally arranged on the sliding mounting frame 32. The length direction of the threaded rod 354 is consistent with the length direction of the sliding mounting frame 32. The threaded seat 355 is fixedly mounted on the rotating transmission frame 33. The threaded rod 354 is threadedly matched with the threaded seat 355. The driven tooth 353 is fixedly mounted on the end of the threaded rod 354. The second driving tooth 352 is meshed with the driven tooth 353.

[0042] The present invention can match the clamping and grinding functions of automobile brake shoes 5 with different curvatures by adjusting the horizontal extension length of the sliding mounting frame 32 according to the different specifications of the automobile brake shoes 5, thereby adapting to the clamping and grinding operations of different automobile brake shoes 5 and improving adaptability. The output of the rotary driver 351 drives the second driving tooth 352 fixedly connected thereto to rotate, and the second driving tooth 352 drives the driven tooth 353 meshing therewith to rotate, thereby driving the threaded rod 354 fixedly connected to the driven tooth 353 to rotate synchronously. When the threaded rod 354 rotates, it realizes the sliding drive function in the horizontal direction through the threaded seat 355, forcing the sliding mounting frame 32 and the rotating transmission frame 33 to slide along the length direction of the sliding mounting frame 32. At this time, the distance between the deflection drive mechanism 4 and the grinding mechanism 6 relative to the rotating center column 31 is changed, thereby changing the deviation correction and grinding stroke, thereby adapting to different models of automobile brake shoes 5.

[0043] The support assembly 36 includes a support rib 361, a second sliding groove 362 and a fixed seat 363. The fixed seat 363 is rotatably mounted on the rotating center column 31 through a bearing. The fixed seat 363 is located below the sliding mounting frame 32. The support rib 361 is fixedly mounted on the fixed seat 363. The support end of the support rib 361 is in contact with the ground of the sliding mounting frame 32. The bottom of the sliding mounting frame 32 is slidably connected to the support rib 361 through the second sliding groove 362.

[0044] The support ribs 361 can improve the stability of the sliding mounting frame 32, ensuring the accuracy of the deflection drive mechanism 4 and the grinding mechanism 6 installed thereon during operation. At the same time, the setting of the second sliding groove 362 ensures that the sliding mounting frame 32 can slide relative to the rotating center column 31, thereby not interfering with the adaptive adjustment function.

[0045] A visual inspection camera 321 is vertically arranged at one end of the sliding mounting frame 32 close to the automobile brake shoe 5 , and a first sliding groove 322 for slidingly cooperating with the rotating transmission frame 33 is arranged on the inner side of the sliding mounting frame 32 .

[0046] The visual inspection camera 321 can detect the size of the automobile brake shoe 5 to be processed, so that the length of the sliding mounting frame 32 can be adaptively adjusted to match the processing stroke required for the automobile brake shoe 5. The first sliding groove 322 facilitates precise sliding between the sliding mounting frame 32 and the rotating transmission frame 33 to prevent jamming between the sliding mounting frame 32 and the rotating transmission frame 33.

[0047] The brake shoe clamping assembly 23 includes a side support frame 231, a first clamping cylinder 232 and a first clamping plate 233. The side support frame 231 is fixedly mounted on the output end of the second pushing assembly 21, the first clamping cylinder 232 is fixedly mounted on the side support frame 231, the first clamping plate 233 is arranged on the output end of the first clamping cylinder 232, and a rubber anti-slip pad is provided on the first clamping plate 233.

[0048] The output of the second pushing component 21 drives the side support frame 231 to move toward the direction close to the automobile brake shoe 5. After the automobile brake shoe 5 completes the correction operation of its own position, it is driven by the first clamping cylinder 232 to drive the first clamping plates 233 at the upper and lower ends of the inner support rib 52 to move toward the center, thereby clamping the inner support rib 52 located in the middle position of the two first clamping plates 233, realizing the clamping function of the automobile brake shoe 5, and facilitating the subsequent grinding operation.

[0049] The inner resistance component 24 includes a second pressure sensor 241, a connecting plate 242 and a second roller 243. The second pressure sensor 241 is fixedly mounted on the output end of the third pushing component 22. The connecting plate 242 is horizontally arranged. Two second rollers 243 are provided. The two second rollers 243 are symmetrically arranged on both sides of the central pushing plate 131 along the vertical center plane of the central pushing plate 131. The two second rollers 243 are vertically arranged. The second rollers 243 are fixedly connected to the second pressure sensor 241 through the connecting plate 242.

[0050] When the third pushing component 22 is outputting, the inner resistance component 24 installed on the output end of the third pushing component 22 is pushed forward, so that the second roller 243 close to the automobile brake shoe 5 resists the inner wall of the inner supporting rib 52, and cooperates with the first resistance component 13 to realize the lateral limit clamping of the automobile brake shoe 5. The resistance force between the second roller 243 and the automobile brake shoe 5 can be detected by the second pressure sensor 241. The connecting plate 242 is used to connect the second roller 243 to the second pressure sensor 241 and the output end of the third pushing component 22. When the values ​​of the two second pressure sensors 241 are equal, the automobile brake shoe 5 is in a stable state, and the automobile brake shoe 5 can be fixed and clamped by the brake shoe clamping component 23, so that subsequent grinding operations can be carried out.

[0051] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
