Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle brake shoe production, in particular to a shoe friction material stability testing device. Background Art

[0002] The motorcycle brake shoe is one of the key components in the motorcycle braking system, mainly used to provide braking force. It generates friction by contacting with the brake drum, thereby slowing down or stopping the motorcycle.

[0003] During the production of motorcycle brake shoes, a layer of protective material is typically applied to the shoe surface to protect it and ensure its performance. This protective material not only prevents damage during transportation and storage, but also prevents dust and other impurities from adhering to the surface, thereby ensuring the shoe's frictional performance during use. However, the adhesion between the protective paper and the shoe significantly impacts the shoe's quality. Inadequate adhesion can cause the protective paper to fall off during transportation or installation, compromising the shoe's proper function. Therefore, it is necessary to conduct a viscosity strength test on the protective material applied to the shoe.

[0004] Currently, most brake shoe manufacturers use manual testing methods, such as visual inspection or hand-tearing of protective paper to determine adhesion. This method is highly subjective and uncertain, resulting in poor consistency in test results. Utility Model Content

[0055] Combine Figures 1 to 8 As shown, the shoe friction material stability testing equipment includes a workbench 1, a first mounting plate 2, a second mounting plate 3, a slide rod 4, a detection component 5, a first clamping component 6, a driving member 7 and a limit component 8.

[0056] The first mounting plate 2 is arranged on one side of the upper part of the workbench 1; the second mounting plate 3 is arranged on the other side of the upper part of the workbench 1, and a positioning groove 31 is provided on the second mounting plate 3 for placing the shoe; the slide rod 4 is sleeved on both sides between the first mounting plate 2 and the second mounting plate 3; the detection component 5 is slidably sleeved on the two slide rods 4; the first clamping component 6 is arranged on one side of the detection component 5, for clamping and fixing the shoe in the positioning groove 31; the driving member 7 is arranged on one side of the first mounting plate 2, and the output end of the driving member 7 passes through the first mounting plate 2 and is connected to the detection component 5; the limit component 8 is arranged on the upper part of the workbench 1, the limit component 8 is located on one side of the detection component 5, and is in contact with the detection component 5, and the limit component 8 is electrically connected to the driving member 7 for limiting the sliding stroke of the detection component 5.

[0057] Among them, by arranging a sliding rod 4 between the first mounting plate 2 and the second mounting plate 3, and slidingly sleeved on the sliding rod 4, the effect of automatically detecting the viscosity of the protective material on the shoe block can be achieved under the action of the driving member 7, which greatly improves the efficiency of detecting the viscosity of the protective material on the shoe block; by arranging the first clamping component 6 on one side of the detection component 5, and providing a positioning groove 31 on the second mounting plate 3, the first clamping component 6 and the positioning groove 31 are combined to achieve the effect of clamping the shoe block while detecting the viscosity of the protective material on the shoe block; by electrically connecting the limit component 8 with the driving member 7, the limit component 8 can not only control the speed at which the driving member 7 drives the detection component 5 to slide, but also avoid the collision of the detection component 5 with the second mounting plate 3 and the occurrence of overtravel.

[0058] When testing the stickiness of the protective material on the shoe block, it is first necessary to place the shoe block in the positioning groove 31 on the second mounting plate 3. It should be noted that when placing the shoe block, the shoe block is completely located in the positioning groove 31, and the protective material on the shoe block is just above the positioning groove 31. Secondly, the driving member 7 is started, and the output end of the driving member 7 drives the detection component 5 to move along the trajectory of its two sliding rods 4, so that the detection component 5 and the first clamping component 6 gradually approach the shoe block on the second mounting plate 3. In the process of simultaneous movement of the detection component 5 and the first clamping component 6, the first clamping component 6 first approaches the shoe block to fix the shoe block on the second mounting plate 3. The detection component 5 and the first clamping component 6 continue to move until the detection component 5 removes the protective material from the shoe block. The detection component 5 immediately touches the limit component 8, and the limit component 8 sends a corresponding signal to the driving member 7 to stop the driving member 7 and send the working status of the driving member 7 to the corresponding equipment for recording and comparing how much force was used to tear the protective material off the shoe block.

[0059] Combine Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 7 As shown, the detection assembly 5 includes a slider 51, a detection plate 54, and a locking nut 55. The slider 51 has a first mounting slot 52, with a limiting slot 53 defined on one side of the first mounting slot 52. The detection plate 54 is slidably embedded in the first mounting slot 52 and the limiting slot 53. The locking nut 55 is sleeved on both sides of the slider 51. The bottom end of the locking nut 55 passes through the slider 51 and extends into the limiting slot 53, abutting the upper portion of the detection plate 54. The upper portion of the positioning slot 31 has a guide slot 32 defined therein, and the detection plate 54 is slidably embedded in the guide slot 32.

[0060] Among them, the detection plate 54 is detachably mounted on the slider 51 under the combined action of the limit groove 53 and the locking nut 55. When the viscosity of the protective material on the shoe is detected, the output end of the driving member drives the slider 51 to move along the slide rod 4, and the slider 51 drives the detection plate 54 and the first clamping component 6 to move together. The first clamping component 6 first contacts the shoe and fixes it on the second mounting plate 3. The detection plate 54 continues to move and gradually approaches the protective material on the shoe. When the detection plate 54 contacts the protective material on the shoe, force is continued to be applied to gradually peel off the protective material. After the protective material is peeled off, the detection plate 54 continues to move along the track of the guide groove 32 until the slider 51 touches the limit component 8.

[0061] Combine Figure 2 As shown, a first clamping assembly 6 is provided on one side of the slider 51. The first clamping assembly 6 is located above the detection plate 54 and comprises a first spring 61 and a first clamping plate 62. Multiple first springs 61 are provided; the first clamping plate 62 is provided at one end of the first spring 61. The upper portion of the first clamping plate 62 is flush with the upper portion of the positioning slot 31. The first clamping plate 62 is made of rubber.

[0062] Among them, because the first clamping plate 62 is made of rubber material, the first clamping plate 62 can not only clamp the shoe, but also avoid damage to the shoe. When the stickiness of the protective material on the shoe is tested, the output end of the driving member drives the slider 51 to move along the slide bar 4, and the slider 51 drives the detection plate 54 and the first clamping assembly 6 to move together. The first clamping plate 62 first contacts the shoe. Under the action of the driving member 7, the first clamping plate 62 fixes the shoe on the second mounting plate 3, and the first spring 61 is in a compressed state until the detection plate 54 continues to move and gradually approaches the protective material on the shoe. When the detection plate 54 contacts the protective material on the shoe, it continues to apply force to gradually peel off the protective material. After the protective material is peeled off, the detection plate 54 continues to move along the track of the guide groove 32 until the slider 51 touches the limit assembly 8.

[0063] Combine Figure 6 and Figure 7 As shown, a second mounting slot 33 is defined on either side of the positioning slot 31. A second clamping assembly 9 is disposed within the second mounting slot 33. The second clamping assembly 9 comprises a second spring 91 and a second clamping plate 92. Multiple second springs 91 are provided, and the second clamping plate 92 is a rubber plate disposed at one end of the second spring 91.

[0064] Among them, under the action of the second spring 91 and the second clamping plate 92, shoes of different sizes can be tested, which greatly improves the scope of use of the equipment. At the same time, under the action of the second clamping plate 92 being a rubber plate, damage to the shoe during clamping is also avoided.

[0065] Combine Figure 2 and Figure 4 As shown, a contact member 56 is provided on one side of the slider 51, and the contact member 56 contacts the limit assembly 8 to activate the limit assembly 8. Chamfers 561 are provided on both sides of the lower portion of the contact member 56.

[0066] Among them, the design of the chamfer 561 allows the touch member 56 to transition smoothly when approaching the limit assembly 8, reducing impact and wear, and plays a guiding role, making it easier for the touch member 56 to contact the limit assembly 8, ensuring touch accuracy.

[0067] Combine Figure 1 and Figure 8 As shown, the limit assembly 8 includes a mounting bracket 81, a proximity switch 83, and a limit switch 84. A third mounting slot 82 is defined in the mounting bracket 81; the proximity switch 83 is located on one side of the third mounting slot 82; and the limit switch 84 is located on the other side of the third mounting slot 82. The lower portion of the contact member 56 contacts the proximity switch 83 and the limit switch 84. The mounting bracket 81 has a Z-shaped structure.

[0068] Among them, before the touch member 56 touches the proximity switch 83, the driving member 7 drives the slider 51 in a relatively fast stroke. After the touch member 56 touches the proximity switch 83, its stroke is relatively slow, so as to facilitate the accuracy of the detection plate 54 in peeling off the protective material. At the same time, after the touch member 56 touches the limit switch 84, it immediately sends a stop signal to the driving member 7, avoiding the situation where the slider 51 collides with the second mounting plate 3.

[0069] The working mode of the utility model is as follows:

[0070] Place the shoe in the positioning groove 31 on the second mounting plate 3. It should be noted that the shoe should be completely located in the positioning groove 31, and the protective material on the shoe is just above the positioning groove 31 and is on the same horizontal plane as the detection plate 54. Moreover, under the action of the second spring 91 and the second clamping plate 92, the shoe can also be positioned. Secondly, start the driving member 7 again. The output end of the driving member 7 drives the detection component 5 to move along the trajectory of the slide bar 4. At this time, the detection component 5 and the first clamping component 6 begin to gradually approach the shoe on the second mounting plate 3. Since the driving member 7 is driving the slider 51, the slider 51 drives the detection plate 54 and the first clamping plate 62. Before the touch member 56 touches the proximity switch 83, the driving member 7 is relatively fast in the travel of the driving slider 51 until the touch member 56 touches the proximity switch After closing 83, its stroke is relatively slow, so that the detection plate 54 can accurately peel off the protective material. The driving member 7 drives the detection component 5 to move along the slide bar 4. At this time, the detection component 5 and the first clamping component 6 gradually approach the shoe block on the second mounting plate 3. When the first clamping plate 62 in the first clamping component 6 contacts the shoe block, under the action of the driving member 7, the first clamping plate 62 fixes the shoe block on the second mounting plate 3, and the first spring 61 is in a compressed state. The detection component 5 continues to move, and the detection plate 54 gradually approaches the protective material on the shoe block. When the detection plate 54 contacts the protective material on the shoe block, it continues to apply force to gradually peel off the protective material. The second clamping plate 92 in the second clamping component 9 also participates in clamping to ensure that the shoe block is stable and motionless. When the protective material is completely peeled off, the detection plate 54 continues to move along the guide groove 32. The contact member 56 eventually touches the limit switch 84, and the limit assembly 8 sends a stop signal to the driving member 7, and the driving member 7 stops working. The working status of the driving member 7 is recorded, including data such as the force used to peel off the protective material, for subsequent analysis.

[0071] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present invention.
