[0002] A wedge brake shoe is a brake system component for motor vehicles that is usually mounted on the vehicle's brake drum or brake disc and is used to create friction to slow the vehicle; the working principle of a wedge brake shoe is to use the braking force to press two wedge-shaped metal parts together so that they contact the brake disc or brake drum. In this way, the braking force is converted into friction, thereby slowing the vehicle.

[0003] In the process of wedge brake shoe processing, slotting is an important processing step. Slotting can be used to install bolts, pins or other connectors to ensure that the connection between the wedge brake shoe and other components is firm and stable.

[0020] Beneficial Effects

[0021] Compared with the prior art, the present invention provides a special processing device for wedge-shaped brake shoes, which has the following beneficial effects:

[0022] 1. The special equipment for processing wedge-shaped brake horseshoes can clamp the wedge-shaped brake horseshoes to be processed under the elastic force of the fifth spring when the wedge-shaped brake horseshoes to be processed are placed between the two L-shaped limit plates, and then the wedge-shaped brake horseshoes are adsorbed by the magnet to complete the initial positioning, and the first motor drives the transmission column to rotate, and then the height of the clamping block is adjusted, and the clamping block contacts the surface of the wedge-shaped brake horseshoes to be processed and lifts it until the wedge-shaped brake horseshoes to be processed are in contact with the top surfaces of the two L-shaped limit plates to complete the clamping positioning, and the first bevel gear and the second bevel gear are driven, etc. When the wedge-shaped brake horseshoes to be processed are automatically clamped and positioned, the slotting mechanism is also gradually approaching the wedge-shaped brake horseshoes to be processed, thereby optimizing the processing steps of the wedge-shaped brake horseshoes, improving the processing efficiency, and the effect is more obvious in batch processing.

[0023] 2. The special equipment for processing wedge-shaped brake horseshoes utilizes the elasticity of the fifth spring. When wedge-shaped brake horseshoes of different lengths are placed between the two L-shaped limit plates, they can all be clamped and positioned. When the clamping block moves upward to drive the wedge-shaped brake horseshoe to be processed to move upward together, the vertical column, the second T-shaped column and the cross column all move with the movement of the clamping block, and the convex column on the surface of the cross column can be inserted into the groove at the bottom of the L-shaped limit plate, thereby limiting the L-shaped limit plate, thereby ensuring the stable clamping and positioning of the L-shaped limit plate to be processed, that is, after the wedge-shaped brake horseshoes to be processed of different lengths are placed between the two L-shaped limit plates, they can automatically adapt to clamping, and there is no need to adjust the position of the clamp every time the wedge-shaped brake horseshoes of different sizes are replaced, thereby reducing the adjustment time for replacing the wedge-shaped brake horseshoes of different lengths to be processed, and also reducing the operating steps of the operator, so that it is convenient to quickly process the wedge-shaped brake horseshoes of different sizes to be processed.

[0024] 3. The special equipment for processing wedge brake horseshoes, in the process of the slotting mechanism approaching the wedge brake horseshoe to be processed, the movable column first contacts the surface of the wedge brake horseshoe to be processed after clamping and positioning, as the mounting block and the slotting mechanism gradually approach the wedge brake horseshoe to be processed, the pressing block and the surface of the gas flow channel slide relative to each other, compressing the air in the gas flow channel, and when the slotting mechanism slots the surface of the wedge brake horseshoe to be processed, the compressed air in the gas flow channel can be ejected from the nozzle through the check valve, and the debris generated during the slotting is cleared to prevent the debris from adhering to the surface of the wedge brake horseshoe to be processed, thereby ensuring the processing quality.

[0025] 4. The special equipment for processing wedge-shaped brake horseshoes, when the transmission column rotates, the sleeve is driven to rotate by the first bevel gear and the second bevel gear, and the adjusting disk drives the U-shaped block to move back and forth, and then the U-shaped column, the column, the mounting block and the slotting mechanism move back and forth together with the U-shaped block to perform slotting processing. In the process of the third protrusion moving from the first strip groove to the second adjusting groove, since one of the side arms of the U-shaped column is rotatably connected to the bottom of the U-shaped column, when the rotating column does not rotate, one of the side arms of the U-shaped column and the column both rotate, and relative rotation is generated between the arc block and the arc limiting plate, thereby adjusting the position of the mounting block and the slotting mechanism, that is, adjusting the working position of the slotting mechanism, and automatically adjusting the slotting working position in the process of adjusting the slotting mechanism to move back and forth, and when the slotting mechanism completes the first slotting operation, the slotting mechanism can complete the automatic adjustment of the slotting working position in the process of moving away from the wedge-shaped brake horseshoe, thereby shortening the adjustment time and improving the processing efficiency.

The slotting mechanism 317 is similar in structure to the existing slotting device for surface slotting of wedge brake shoes, which includes a drill bit, a second motor, a coupling and a motor seat, etc., which is an existing mature technology and will not be elaborated here.

[0066] It should be noted that the present invention is a special processing equipment for wedge brake shoes. In the initial state, the first spring is in a compressed state. The reaction force generated by the compression of the first spring acts on the surface of the first T-shaped column 223, so that the first protrusion 226 on the surface of the first disc 221 and the second protrusion 227 on the surface of the second disc 222 can be stably engaged, thereby ensuring that the rotation of the transmission column 225 can drive the cylinder 214 to rotate, thereby adjusting the upper and lower positions of the clamping block 215; the initial state of the third spring 313 is a compressed state, and the third spring 313 is compressed. The generated reaction force acts on the surface of the third T-shaped column 314, thereby forming support for the mounting block 316, the slotting mechanism 317, the rectangular column 318 and the arc block 315, so that the arc block 315 is in close contact with the surface of the arc limiting plate 13, ensuring the stability of the slotting mechanism 317 during position adjustment and slotting operations. The initial state of the fourth spring is a compressed state. The reaction force generated by the compression of the fourth spring acts on the surface of the pressing block 3110, which facilitates the resetting of the pressing block 3110 and can also serve as a power for inhaling air into the gas flow channel 319.

[0067] During the overall operation, the wedge-shaped brake shoes to be processed are placed between the two L-shaped limit plates 211. Since the slide groove 11 is slidably connected with the L-shaped limit plates 211, under the elastic force of the fifth spring, the two L-shaped limit plates 211 can be in close contact with the two ends of the wedge-shaped brake shoes to be processed, and the magnet 213 adsorbs the wedge-shaped brake shoes to be processed to complete the preliminary positioning. The first motor 224 drives the transmission column 225 to rotate. The surface of the transmission column 225 is provided with a column groove. The first T-shaped column 223 is slidably connected with the column groove. By utilizing the elastic force of the first spring, the second disk 222 above the first T-shaped column 223 can be stably engaged with the first disk 221 below the cylinder 214, so that the rotation of the transmission column 225 can drive the cylinder 214 to rotate, and the cylinder 214 The cylinder 214 is threadedly connected with the stud 216, and the stud 216 is driven to move upward by the rotation of the cylinder 214. The stud 216 is fixedly connected with the clamping block 215, and the clamping block 215 can move upward with the stud 216. The clamping block 215 contacts the surface of the wedge-shaped brake horseshoe to be processed, and drives the wedge-shaped brake horseshoe to be processed to move upward. During this process, the wedge-shaped brake horseshoe to be processed is in a stable upward moving state until it contacts the tops of the two L-shaped limit plates 211 to complete the clamping positioning. When the wedge-shaped brake horseshoe to be processed completes the clamping positioning, the first motor 224 continues to drive the transmission column 225 to rotate. By utilizing the elasticity of the first spring, relative rotation is generated between the first protrusion 226 and the second protrusion 227, and the rotation of the transmission column 225 cannot drive the cylinder 214 to rotate.

[0068] When the clamp block 215 moves upward and drives the wedge-shaped brake shoe to be processed to move upward, since the vertical column 231 is fixedly connected to the clamp block 215, a vertical groove 232 is provided on the surface of the vertical column 231, and the second T-shaped column 233 is slidably connected to the vertical groove 232, and the cross column 234 is fixedly connected to the second T-shaped column 233. The vertical column 231, the second T-shaped column 233 and the cross column 234 all move with the movement of the clamp block 215. As the clamp block 215 moves upward, the multiple protrusions 235 on the upper surface of the cross column 234 gradually approach the bottom of the L-shaped limiting plate 211. Due to the elastic force of the fifth spring, the L-shaped limiting column is in a stable state, and the protrusion 235 is inserted into the groove 236 to limit the L-shaped limiting plate 211. When the protrusion is inserted into the groove 236, the clamp block 215 continues to move upward, then the first The second T-shaped column 233 and the vertical groove 232 slide relative to each other, and the second spring is compressed. The elastic force of the second spring is used to ensure that the convex column 235 and the groove 236 are stably matched, that is, the L-shaped limiting plate 211 is stably limited until the wedge-shaped brake horseshoe to be processed contacts the top surface of the two L-shaped limiting plates 211. By using the elasticity of the fifth spring, wedge-shaped brake horseshoes of different lengths can be clamped and positioned when placed between the two L-shaped limiting plates 211, and can automatically adapt to clamping. There is no need to adjust the position of the clamp every time a wedge-shaped brake horseshoe of different sizes is replaced, which reduces the adjustment time for replacing wedge-shaped brake horseshoes of different lengths to be processed, and also reduces the operating steps of the operator, so that it is convenient to quickly process wedge-shaped brake horseshoes of different sizes to be processed.

[0069] When the transmission column 225 rotates, since the first bevel gear 321 is fixedly connected to the transmission column 225, the first bevel gear 321 can rotate as the transmission column 225 rotates, and the outer side of the first bevel gear 321 is meshedly connected with the second bevel gear 322, and the second bevel gear 322 can rotate as the first bevel gear 321 rotates. The sleeve 323 is fixedly connected to the second bevel gear 322, and the sleeve 323 rotates as the second bevel gear 322 rotates. The second bevel gear 322 rotates slower than the first bevel gear 321, which plays a deceleration role. The adjusting disk 324 is fixedly connected to the sleeve 323 The adjusting disk 324 rotates with the rotation of the sleeve 323, the sleeve 323 is slidably connected with the U-shaped column 325, and the U-shaped column 325 is limited in movement. The adjusting disk 324 is installed in cooperation with the U-shaped block 326. Since the adjusting disk 324 is inclined, the adjusting disk 324 can drive the U-shaped block 326 to move back and forth when it rotates. The U-shaped block 326 is fixedly connected with the U-shaped column 325. The U-shaped column 325 moves with the movement of the U-shaped block 326. A first circular groove 327 is provided on the surface of the U-shaped column 325. The third protrusion 3211 is fixedly connected to the groove wall of the first circular groove 327. The block 3211 is slidably connected with the first strip groove 3210. As the adjusting disk 324 rotates, the third protrusion 3211 slides along the surface of the first strip groove 3210, and then cooperates with the spiral groove 329 to drive the rotating column 328 to rotate, and then slides along the surface of the second strip groove. Since the L-shaped mounting plate and the rotating column 328 are rotatably connected through a one-way bearing, in the process of the third protrusion 3211 moving from the first strip groove 3210 to the second adjusting groove, the third protrusion 3211 cooperates with the spiral groove 329 to drive the rotating column 328 to rotate, and the U-shaped column 325 moves away from the sleeve. When the cylinder 323 moves in the direction of rotation, the third protrusion 3211 cooperates with the spiral groove 329 and cannot drive the rotating column 328 to rotate. Since one of the side arms of the U-shaped column 325 is rotatably connected to the bottom of the U-shaped column 325, when the rotating column 328 does not rotate, one of the side arms of the U-shaped column 325 and the column 311 both rotate, and a relative rotation occurs between the arc block 315 and the arc limit plate 13, thereby adjusting the position of the mounting block 316 and the slotting mechanism 317, that is, adjusting the operating position of the slotting mechanism 317. In the process of adjusting the slotting mechanism 317 to move back and forth, the slotting operating position is automatically adjusted;

[0070] The elastic force of the third spring 313 is used to support the mounting block 316, the slotting mechanism 317, the rectangular column 318 and the arc block 315, so that the arc block 315 is in close contact with the surface of the arc-shaped limit plate 13, ensuring the stability of the slotting mechanism 317 during position adjustment and slotting operations. The mounting block 316, the slotting mechanism 317 and the rectangular column 318 move with the movement of the U-shaped column 325, and the movable column 3114 first contacts the surface of the wedge brake shoe to be processed after the clamping and positioning is completed. As the mounting block 316 and the slotting mechanism 317 gradually approach the wedge-shaped brake shoe to be processed, the pressing block 3110 slides relative to the surface of the gas flow channel 319, compressing the air in the gas flow channel 319. When the slotting mechanism 317 slots the surface of the wedge-shaped brake shoe to be processed, the compressed air in the gas flow channel 319 can be ejected from the nozzle 3117 through the check valve 3113 to remove the debris generated during the slotting, thereby ensuring the processing quality.

[0071] It should be noted that the arc-shaped limit plate 13 and the support frame 12 can be fixedly connected by bolts or by locks. For wedge-shaped brake horseshoes to be processed of different specifications, the upper and lower positions of the arc-shaped limit plate 13 can be adjusted or different arc-shaped plates can be replaced to adapt to processing. At the same time, by replacing the corresponding rotating column 328, the third protrusion 3211 is matched with different spiral grooves 329, thereby adjusting the working position of the grooving mechanism 317. For batch processing of the same type of wedge-shaped brake horseshoes, the processing efficiency can be improved.
