Description

Technical Field

[0001] The invention relates to the field of grinding and polishing machine tools, in particular to an outer arc grinding machine for automobile disc brake pads. Background Art

[0002] The outer arc grinder for automobile disc brake pads is a kind of equipment specially used for processing the outer arc of automobile brake pads. It plays an important role in the field of automobile parts processing technology. In automobile parts manufacturing enterprises, it is used for the production and processing of brake pads. The outer arc grinder helps to improve the quality and performance of brake pads. The Chinese patent with the existing authorization announcement number CN216883204U discloses an external arc grinder for automobile drum brake pads, including a grinder device, the grinder device including a working platform and a movable support block on the working platform, a servo motor is arranged on the upper side of the movable support block, a grinding disc is arranged on the output end of the servo motor, and a point pressure type self-rotation positioning device is arranged on the side close to the grinding disc, the point pressure type self-rotation positioning device includes a mounting seat and a turntable, the turntable is located at the center position of the upper side of the mounting seat, and support frames are arranged at the two edge positions of the upper side of the mounting seat, each support frame is rotatably connected to a transmission frame at the upper end, and an electric push rod is arranged on the lower side of each transmission frame, as well as a point contact anti-skid positioning block at the lower end of each electric push rod, so that the surface contact positioning mode can be changed to the point contact positioning mode, so as to avoid the obstruction of the drum brake pad during the grinding process, and the point pressure type self-rotation positioning device has universal practicality for drum brake pads of different sizes, and has certain practical value; However, the automobile drum brake pad outer arc grinder still has the following defects: 1. Although the brake pad is fixed by point contact to avoid front obstruction, the fixing method is to press the brake pad on the base. Static clamping can easily cause the brake pad to be offset during processing, affecting the consistency of the forming surface. Therefore, the brake pad needs to be turned over manually, and the fixing device cannot rotate the brake pad at the same frequency as the working speed of the grinding head, ensuring that the bottom of the grinding head is always the ungrinded brake pad. The automation effect of the device is not enough; 2. The device is fixed with a clamping point, but the brake pads used for tires of different sizes are different in size. When the size of the brake disc is too large or too small, the device is not convenient to adapt to the size of the brake pad. It is necessary to replace the fixture or adjust the mechanical structure to adapt to the brake pads of different sizes. The downtime adjustment time is long, which affects the production efficiency; 3. In addition, the outer arc grinding of the brake disc can only grind the two sides and ends of the brake disc horizontally, and cannot chamfer the edges of the brake pads. Limited by the freedom of the grinding head, it is difficult to perform full-circumferential continuous grinding on the turning point of the other arc edge of the brake pad, resulting in insufficient local precision of the brake pad. The sharp edges make the brake pads easy to break and wear during use, and cause greater damage to the tires and wheels during use. Summary of the invention

[0013] Furthermore, a support base is installed at the bottom end of the grinding machine operating table, and a controller is installed on one side of the support base, and a grinder top cover is installed at the top end of the grinding machine operating table.

[0014] The present invention provides an automobile disc brake pad outer arc grinder through improvement, which has the following improvements and advantages compared with the prior art: Firstly, the device fixes the disc brake pad template on the inner side of the movable plate through a T-shaped support frame, and the device can simultaneously avoid the fixed structure from blocking the front and back sides of the disc brake pad template, and by starting the second motor to drive the flip bracket to flip, the angle of the disc brake pad template can be flexibly adjusted, and the disc brake pad template can be automatically flipped. At the same time, the transmission telescopic rod is started to control the multi-layer grinding head to adjust the direction facing the disc brake pad template, so as to achieve the same frequency rotation of the brake pad according to the grinding effect of the grinding head, and ensure that the bottom end of the grinding head is always an ungrinded brake pad, thereby improving the automation effect of the device, reducing manual operations, shortening installation time, and improving work efficiency; The specific working process is to start the first motor to drive the transmission gear to rotate, the transmission gear drives the transmission sprocket to rotate, thereby driving the disc brake pad template to rotate about the center line of the transmission sprocket, when the first motor stops, start the stop telescopic rod to extend the stop plug-in so that the stop plug-in and the slot at the bottom of the transmission sprocket are stuck, thereby stopping the transmission sprocket; the transmission sprocket drives the supporting bracket to rotate, start the second motor to drive the first pulley to rotate through the transmission belt, the first pulley drives the flip bracket to rotate, thereby driving the disc brake pad template to rotate about the center line of the first pulley, start the third motor, the third motor drives the transmission screw to rotate, and the threaded transmission of the screw drives the internal thread slider and the bottom movable plate along the X-axis limit rod. The cam is moved in the direction of rotation, and the top and bottom ends of the disc brake pad template are respectively fixed to the second movable belt and the first movable belt by a T-shaped support frame and a movable slider, one end of the movable slider is fixed to the second movable belt and the first movable belt by buckling, and one end of the movable slider away from the second movable belt and the first movable belt is slidably connected to the Y-axis limiting slide rail, thereby driving the disc brake pad template to move along the direction of the Y-axis limiting slide rail, and the above four groups of transmission structures for adjusting the position of the disc brake pad template are coordinated to achieve the effect of rotating the brake pad at the same frequency according to the grinding effect of the grinding head, ensuring that the bottom end of the grinding head is always an ungrinded brake pad, thereby improving the automation effect of the device, reducing manual operation, shortening installation time, and improving work efficiency.

[0015] Then, when the second movable belt and the first movable belt move, they will drive the second spur gear and the first spur gear to rotate, and the second spur gear and the first spur gear will drive the transmission flat slide bar to rotate. The square sliders at both ends of the transmission flat slide bar can drive the limiting slide groove to rotate, and the limiting slide groove drives the second spur gear and the first spur gear on the other side of the movable flap to rotate, thereby driving the parts on the other set of movable flaps to move. Finally, start the transmission telescopic rod to extend and retract. The output end of the transmission telescopic rod is hingedly connected to the support base plate through a U-shaped hinge. When the transmission telescopic rod is pushed out, it will drive the support base plate to flip around the hinge point of the support base plate and the support side plate, thereby driving the multi-layer grinding head and protective cover of the grinding motor at the top to flip.

[0016] Secondly, another device fixes the center point of the disc brake pad template through a T-shaped support frame, and the disc brake pad template can rotate around the center point. In addition, the center point is fixed by a knob, and the tightness of the fixation can be adjusted by rotation. When loosening, the disc brake pad template can rotate around the center point to avoid the T-shaped support frame blocking the part that cannot be polished. When tightening, the disc brake pad template can be fixed to facilitate the outer arc chamfer polishing structure polishing, and the movable slider can use T-shaped support frames of different lengths according to the size of the disc brake pad template; in addition, the second movable belt and the first movable belt are both arranged around the Y-axis limit slide rail, and the movable slider can be selected according to the disc brake pad templates of different thicknesses. It is installed at the top or bottom of the Y-axis limit rail to adapt to brake pads of different thicknesses and widths, and the movable slider can choose to install the disc brake pad template horizontally or vertically according to the needs of use. In addition, when the movable slider is fixed on the side close to the limit auxiliary roller, the limit auxiliary roller will be blocked in the middle. At this time, the movable position of the movable slider is limited and the movable slider needs to be manually disassembled and installed; when the second movable belt and the first movable belt move, the movable slider will move, thereby driving the disc brake pad template to move, and further bringing the disc brake pad template close to the multi-layer grinding head. This step can not only adjust the grinding accuracy, but also adjust the moving position according to brake pads of different sizes; Because the second movable belt and the first movable belt need to pull the disc brake pad template to drive the disc brake pad template to move, the pressure they are subjected to is relatively large, so the second movable belt and the first movable belt will loosen without support in the middle. The limiting auxiliary roller is located in the middle of the movable plate, and the limiting auxiliary roller is provided with three groups of limiting auxiliary rollers at both ends. The limiting auxiliary rollers are located at the bottom to press down the second movable belt, and the middle limiting auxiliary roller is located at the top to support the second movable belt. The purpose of the staggered distribution is to cooperate with the third gear to play a supporting role in the middle of the second movable belt, so as to avoid the second movable belt in the middle from loosening due to insufficient supporting force, thereby ensuring the stable operation of the belt transmission. In addition, the purpose of having two sets of movable flaps is to install two sets of disc brake pad templates to improve the working efficiency of the device. When installing two sets of disc brake pad templates, the T-shaped support frame needs to install the disc brake pad template vertically so that the edge of the disc brake pad template can be close to the grinding end of the multi-layer grinding head. The other two sets of movable flaps are driven by the first spur gear and the second spur gear. The transmission flat slide bar and the limiting slide groove drive the transmission between the two sets of movable flaps, but will block the grinding end on one side. Therefore, when two sets of disc brake pad templates need to be polished, the disc brake pad template needs to be installed vertically.

[0017] Thirdly, because the device can start the second motor through the control controller to drive the flip bracket to flip and rotate around the central axis of the first pulley to adjust the angle of the disc brake pad template, it can also start the third motor to drive the movable plate on one side to move along the transmission screw, thereby moving the movable plate in the X-axis direction. In addition, starting the fourth motor can drive the second movable belt and the first movable belt to move, thereby driving the disc brake pad template to move in the Y-axis direction. In addition, the outer arc chamfering grinding structure drives the supporting bottom plate to flip around the hinge point with the supporting side plate by starting the transmission telescopic rod to extend and retract, thereby driving the top multi-layer grinding head to flip; in addition, the first motor drives the transmission gear disk to rotate, which can drive the supporting bracket to rotate around the central axis of the transmission gear disk, thereby driving the disc brake pad template to rotate, and the stop telescopic rod extends and retracts to drive the stop plug-in and the transmission gear disk to engage, thereby stopping the transmission gear disk from rotating, preventing the centrifugal force of the transmission gear disk from being too large, resulting in the transmission gear disk still rotating after the first motor stops, thereby affecting the accuracy of the grinding disc brake pad template. Through the cooperation of the above four sets of transmission structures for adjusting the position of the disc brake pad template, the edge of the brake pad can be chamfered. The grinding head and the clamping structure have a high degree of freedom, and the turning point of the other arc edge of the brake pad can be ground continuously in the whole circumference to improve the local accuracy of the brake pad. The sharp edge of the brake pad can also be ground into an arc chamfer to improve the processing accuracy, ensure the smoothness of the arc surface grinding of the brake pad, and avoid the collapse and wear of the brake pad during use, and avoid the sharp edge of the brake pad from causing damage to the tire and wheel hub during use. Finally, the role of the protective cover is to have a baffle protection function, which maintains the stability of the brake pad during the grinding process and prevents the multi-layer grinding head from working for too long and causing metal fatigue, causing the multi-layer grinding head to fly off during the grinding process or local parts to be damaged and fly off, thereby injuring the staff.

The movable slider 326 is provided with a T-shaped support frame 327 on one side away from the Y-axis limiting slide rail 325, and the movable slider 326 is provided with two groups, and the T-shaped support frames 327 on one side of the two groups of movable sliders 326 are respectively installed at the two ends of the disc brake pad template 7; the top and bottom ends of the disc brake pad template 7 are respectively fixed to the second movable belt 328 and the first movable belt 323 through the T-shaped support frame 327 and the movable slider 326, and one end of the movable slider 326 is fixed to the second movable belt 328 and the first movable belt 323 by buckling, and the movable slider 326 is provided with two groups of T-shaped support frames 327 on one side of the two groups of movable sliders 326. One end of the slider 326 away from the second movable belt 328 and the first movable belt 323 is slidably connected to the Y-axis limiting slide rail 325, thereby driving the disc brake pad template 7 to move along the direction of the Y-axis limiting slide rail 325. When the second movable belt 328 and the first movable belt 323 move, the movable slider 326 will be driven to move, thereby driving the disc brake pad template 7 to move, and further the disc brake pad template 7 is brought close to the multi-layer grinding head 606. This step can not only adjust the grinding accuracy, but also adjust the moving position according to the brake pads of different sizes. In addition, the device fixes the center point of the disc brake pad template 7 through the T-shaped support frame 327, and the disc brake pad template 7 can rotate around the center point. In addition, the center point is fixed by a knob, and the tightness of the fixation can be adjusted by rotation. When the adjustment is loose, the disc brake pad template 7 can rotate around the center point to avoid the T-shaped support frame 327 blocking the grinding. When the adjustment is tight, the disc brake pad template 7 can be fixed to facilitate the grinding of the outer arc chamfer grinding structure 6. The movable slider 326 can use T-shaped support frames 327 of different lengths according to the size of the disc brake pad template 7; in addition, the second movable belt 328 and the first movable belt 323 are both arranged around the Y-axis limiting slide rail 325, and the movable slider 326 can be installed at the top or bottom of the Y-axis limiting slide rail 325 according to the disc brake pad template 7 of different thicknesses, so as to adapt to brake pads of different thicknesses and widths. The movable slider 326 can be used to install the disc brake pad template 7 horizontally or vertically according to the use requirements. In addition, when the movable slider 326 is fixed to the side close to the position-limiting auxiliary roller 324, the position-limiting auxiliary roller 324 will be blocked in the middle, and the movable position of the movable slider 326 is limited, and the movable slider 326 needs to be manually disassembled and installed; Through the above four groups of transmission structures for adjusting the position of the disc brake pad template, the effect of rotating the brake pad at the same frequency according to the grinding effect of the grinding head is achieved, ensuring that the bottom end of the grinding head is always an ungrinded brake pad, thereby improving the automation effect of the device, reducing manual operations, shortening installation time, and improving work efficiency; In addition, because the device can start the second motor 306 by controlling the controller 5 to drive the flip bracket 309 to flip and rotate around the central axis of the first pulley 308 to adjust the angle of the disc brake pad template 7, it can also start the third motor 310 to drive the movable flap 319 on one side to move along the transmission screw 311, thereby moving the movable flap 319 in the X-axis direction. In addition, starting the fourth motor 314 can drive the second movable belt 328 and the first movable belt 323 to move, thereby driving the disc brake pad template 7 to move in the Y-axis direction. In addition, the outer arc chamfering grinding structure 6 drives the transmission telescopic rod 602 to extend and retract. The support bottom plate 604 flips around the hinge point with the support side plate 601, thereby driving the multi-layer grinding head 606 on the top to flip; in addition, the first motor 302 drives the transmission gear disc 304 to rotate, which can drive the support bracket 305 to rotate around the central axis of the transmission gear disc 304, thereby driving the disc brake pad template 7 to rotate, and the stop telescopic rod 331 is extended to drive the stop plug-in 332 and the transmission gear disc 304 to engage, thereby stopping the rotation of the transmission gear disc 304, preventing the centrifugal force of the transmission gear disc 304 from being too large, resulting in the transmission gear disc 304 still rotating after the first motor 302 stops, thereby affecting the accuracy of the grinding disc brake pad template 7. Therefore, through the above four groups of transmission structures for adjusting the position of the disc brake pad template, not only can the effect of rotating the brake pad at the same frequency according to the grinding effect of the grinding head be achieved, but also the edge of the brake pad can be chamfered through the transmission telescopic rod 602. The grinding head and the clamping structure have a high degree of freedom, and can perform full-circumferential continuous grinding on the turning point of the other arc edge of the brake pad to improve the local accuracy of the brake pad. It can also grind an arc chamfer at the sharp edge of the brake pad to improve the processing accuracy, ensure the smoothness of the arc surface grinding of the brake pad, and avoid the collapse and wear of the brake pad during use, and avoid the sharp edge of the brake pad from causing damage to the tire and wheel hub during use; The top end of the second movable belt 328 is in contact with the limited auxiliary roller 324, and the limited auxiliary roller 324 is provided with three groups, and the three groups of limited auxiliary rollers 324 are staggeredly installed at the top end of one side of the movable flap 319; Because the second movable belt 328 and the first movable belt 323 need to pull the disc brake pad template 7 to drive the disc brake pad template 7 to move, the pressure they are subjected to is relatively large, so the second movable belt 328 and the first movable belt 323 will loosen without support in the middle. The limiting auxiliary roller 324 is located in the middle of the movable flap 319, and the limiting auxiliary roller 324 is provided with three groups of limiting auxiliary rollers 324 at both ends. The limiting auxiliary rollers 324 are located at the bottom to press down the second movable belt 328, and the limiting auxiliary rollers 324 in the middle are located at the top to support the second movable belt 328. The purpose of the staggered distribution is to cooperate with the third gear 329 to play a supporting role in the middle of the second movable belt 328, so as to avoid the second movable belt 328 in the middle from loosening due to insufficient support force, thereby ensuring the stable operation of the belt transmission. The outer arc chamfer grinding structure 6 includes a supporting side plate 601, which is installed on one side of the grinding machine operating table 2. A transmission telescopic rod 602 is installed on one side of the supporting side plate 601. The transmission telescopic rod 602 is started to extend and retract, and a multi-layer grinding head 606 is provided at the top of the transmission telescopic rod 602. The top end of the supporting side plate 601 is hingedly connected to the supporting bottom plate 604, the output end of the transmission telescopic rod 602 is installed with a U-shaped hinge 603, and the top end of the U-shaped hinge 603 is hingedly connected to the bottom end of the supporting bottom plate 604, and the output end of the transmission telescopic rod 602 is hingedly connected to the supporting bottom plate 604 through the U-shaped hinge 603. Among them, a grinding motor 605 is installed on one side of the top of the supporting base plate 604, and a multi-layer grinding head 606 is installed at the output end of the grinding motor 605. A protective cover 607 is provided on the top of the multi-layer grinding head 606. When the transmission telescopic rod 602 is pushed out, it will drive the supporting base plate 604 to flip around the hinge point of the supporting base plate 604 and the supporting side plate 601, thereby driving the top grinding motor 605, the multi-layer grinding head 606 and the protective cover 607 to flip, and one side of the protective cover 607 is fixed to the grinding motor 605. The function of the protective cover 607 is to have a baffle protection function to maintain the stability of the brake pad during the grinding process, and prevent the multi-layer grinding head 606 from working for too long and metal fatigue causing the multi-layer grinding head 606 to bounce off during the grinding process or partial parts to be damaged and bounce off, thereby injuring the staff.

[0022] A support base 4 is installed at the bottom of the grinding machine operating table 2 , and a controller 5 is installed on one side of the support base 4 . A grinding machine top cover 1 is installed at the top of the grinding machine operating table 2 .

[0023] The device fixes the disc brake pad template 7 on the inner side of the movable flap 319 through a T-shaped support frame 327. The device can simultaneously avoid the fixed structure from blocking the front and back sides of the disc brake pad template 7, and by starting the second motor 306 to drive the flip bracket 309 to flip, the angle of the disc brake pad template 7 can be flexibly adjusted, and the disc brake pad template 7 can be automatically flipped. At the same time, the transmission telescopic rod 602 is started to control the multi-layer grinding head 606 to adjust the direction facing the disc brake pad template 7, so as to achieve the same frequency rotation of the brake pad according to the grinding effect of the grinding head, and ensure that the bottom end of the grinding head is always an ungrinded brake pad, thereby improving the automation effect of the device, reducing manual operation, shortening installation time, and improving work efficiency.

[0024] Working principle: First, the first motor 302 is started to drive the transmission gear 303 to rotate, and the transmission gear 303 drives the transmission sprocket 304 to rotate, thereby driving the disc brake pad template 7 to rotate about the center line of the transmission sprocket 304. When the first motor 302 stops, the stopping telescopic rod 331 is started to extend the stopping plug-in 332 so that the stopping plug-in 332 and the card slot at the bottom end of the transmission sprocket 304 are stuck, thereby stopping the transmission sprocket 304; the transmission sprocket 304 drives the supporting bracket 305 to rotate, and the second motor 306 is started to drive the first pulley 308 to rotate through the transmission belt 307, and the first pulley 308 drives the flip bracket 309 to rotate, thereby driving the disc brake pad template 7 to rotate about the center line of the first pulley 308, and the third motor 310 is started. The third motor 310 drives the transmission screw 311 to rotate, and the internal thread slider 312 and the movable flap at the bottom are driven by the thread transmission of the screw. 319 moves along the direction of the X-axis limit rod 313. In addition, the top and bottom ends of the disc brake pad template 7 are respectively fixed to the second movable belt 328 and the first movable belt 323 through the T-shaped support frame 327 and the movable slider 326. One end of the movable slider 326 is fixed to the second movable belt 328 and the first movable belt 323 by snapping. The end of the movable slider 326 away from the second movable belt 328 and the first movable belt 323 is slidably connected to the Y-axis limit slide rail 325, thereby driving the disc brake pad template 7 to move along the direction of the Y-axis limit slide rail 325. Through the above four groups of transmission structures for adjusting the position of the disc brake pad template 7 and the transmission telescopic rod 602, the brake pad can be rotated at the same frequency according to the grinding effect of the grinding head, ensuring that the bottom end of the grinding head is always an ungrinded brake pad, thereby improving the automation effect of the device, reducing manual operation, shortening installation time, and improving work efficiency.

[0025] Then, when the second movable belt 328 and the first movable belt 323 move, the second spur gear 333 and the first spur gear 320 will be driven to rotate, and the second spur gear 333 and the first spur gear 320 will drive the transmission flat slide bar 321 to rotate. The square sliders at both ends of the transmission flat slide bar 321 can drive the limiting slide groove 322 to rotate, and the limiting slide groove 322 drives the second spur gear 333 and the first spur gear 320 on the other side of the movable flap 319 to rotate, thereby driving the parts on the other group of movable flaps 319 to move.

[0026] Finally, the transmission telescopic rod 602 is started to extend and retract. The output end of the transmission telescopic rod 602 is hingedly connected to the support base plate 604 through a U-shaped hinge 603. When the transmission telescopic rod 602 is pushed out, it will drive the support base plate 604 to flip around the hinge point between the support base plate 604 and the support side plate 601, thereby driving the top grinding motor 605, the multi-layer grinding head 606 and the protective cover 607 to flip.
