[0020] In summary, the present invention includes at least one of the following beneficial technical effects:

[0021] 1. By setting up multiple support rods, multi-point support for the brake pad is achieved, and at the same time, the obstruction and influence on the drill bit during the drilling of the brake pad can be reduced, the brake pad is supported favorably, and the drilling accuracy is further improved; and for brake pads with different hole positions, the position of the support rod can be adjusted by sliding the support rod, thereby improving the application range of the device.

[0022] 2. By setting a fixing mechanism, when the brake pad placed on the rotating cylinder needs to be fixed, the brake pad is placed in the corresponding placement groove in the rotating cylinder, and then the brake pad is clamped and fixed, and the rebound telescopic rod is pressed into the middle plate. During the rotation process, the return pressure plate will automatically contract the telescopic cylinder, drive the connecting rope to extend, and the connecting elastic member to extend, and the clamping block is extended. The clamping blocks at both ends are extended at the same time to tighten the two ends of the brake pad to fix the brake pad on the rotating cylinder; when the processed brake pad needs to be taken out, the rebound telescopic rod is separated from the return pressure plate, and under the action of the rebound member, the rebound telescopic rod is extended to retract the clamping block into the middle plate to facilitate the placement of the next brake pad; with the above cycle, the fixing and removal of the brake pad are more convenient, and the fixing is more stable, which improves the processing efficiency of the brake pad while providing stable processing accuracy.

[0023] 3. By setting up a cleaning component, after the drilling process of a brake pad is completed, the debris generated during the processing will fall into the placement groove. Under the guidance of the cleaning plate, the debris will slide into the receiving groove, and the remaining debris will be blown away by the high-pressure gas of the air duct, reducing the possibility of residue. At the same time, during the blowing process, the brake pad that has not automatically detached from the rotating cylinder can be blown off and fall into the receiving groove, thereby improving the reliability of the device; at the same time, it reduces the influence of the debris on subsequent processing and improves the processing accuracy of the device.

[0024] 4. By setting up a loading mechanism, when loading is needed, the staff opens the workbench in advance and places the unprocessed brake pads on the discharge plate, and multiple groups can be placed side by side at the same time; when loading, the guide telescopic cylinder adjusts the height of the guide plate and the distance between the rotating cylinder to the loading distance of the brake pad, and the push telescopic cylinder pushes multiple brake pads into the outside of the rotating cylinder at the same time through the push plate, and then pushes it so that the push plate abuts against the middle plate, and the push plate presses the rebound telescopic rod into the middle plate, and then clamps and fixes the brake pads that have just been loaded, and then rotates the rotating cylinder; rotates to the next empty position to be loaded, retracts the push plate, and the discharge plate rises to lift a new layer of brake pads; the above cycle completes the loading, improves the loading efficiency of the brake pad, and enables loading and clamping to be carried out simultaneously, which greatly improves the processing efficiency.

[0025] 5. By setting up a drilling mechanism, when drilling is required, the first drill or the second drill that has been adjusted in position is used through the lifting component or the pushing component to drill holes in the brake pad, or the two brake pads on the top and the side are drilled at the same time, thereby improving the drilling efficiency; when the drilling angle needs to be adjusted, the drilling angle can be adjusted by rotating the rotating cylinder, thereby improving the operability of the processing; when the drilling distance or position needs to be adjusted, the adjustment block is driven to move by the adjustment motor of the adjustment component, so that the two relative first drills or second drills can adjust their positions to each other at the same time, thereby improving the processing efficiency.

DETAILED DESCRIPTION

[0035] The following is combined with Figures 1 to 8 The present invention is described in further detail.

[0036] The embodiment of the present invention discloses a drilling machine for processing automobile brake pads. Figures 1 to 8 A drilling machine for processing automobile brake pads mainly includes a workbench 100, a fixing mechanism 200 and a drilling mechanism 400. The fixing mechanism 200 includes a fixing frame 210, a rotating cylinder 220, a support rod 250 and a plurality of fixing components 230 for fixing and clamping the brake pads. The fixing frame 210 is arranged on the workbench 100, the rotating cylinder 220 is rotatably arranged on the fixing frame 210, a placement groove 240 is opened on the rotating cylinder 220, the fixing component 230 is arranged in the placement groove 240 of the rotating cylinder 220, a plurality of support rods 250 are arranged, and both ends of the support rods 250 are slidably arranged on the rotating cylinder 220 by means of sliders and sliding grooves, and in the placement groove 240 of the rotating cylinder 220.

[0037] The fixing assembly 230 includes a fixing motor 231, an intermediate plate 232, a plurality of clamping blocks 233, a resilient telescopic rod 234, a connecting elastic member 235, a connecting rope 236, a resilient member 237 and a back pressure plate 238. The intermediate plate 232 is arranged on the rotating cylinder 220, and the axial direction of the intermediate plate 232 is parallel to the axis of the rotating cylinder 220. The resilient telescopic rod 234 is slidably arranged in the intermediate plate 232, and the clamping block 233 is slidably arranged in the intermediate plate 232. The resilient telescopic rod 234 is connected to the clamping block 233 by a connecting rope 236. The connecting elastic member 235 is sleeved on the connecting rope 236, and One end is connected to the clamping block 233, and the other end is connected to the middle plate 232. One end of the rebound member 237 is arranged on the middle plate 232, and the other end of the rebound member 237 is arranged on the rebound telescopic rod 234. One rebound telescopic rod 234 corresponds to multiple clamping blocks 233, and one middle plate 232 corresponds to two rebound telescopic rods 234, and the clamping directions of the clamping blocks 233 on the two rebound telescopic rods 234 are different. The return pressure plate 238 is arranged on the fixed frame 210, the fixed motor 231 is arranged on the fixed frame 210, and the rotating cylinder 220 is transmission-connected to the driving end of the fixed motor 231.

[0038] The drilling mechanism 400 includes a mounting frame 401, multiple first drills 402 and a lifting assembly 410 for lifting the first drills 402 along a first direction. The mounting frame 401 is set on the workbench 100, the lifting assembly 410 is set on the mounting frame 401, and the multiple first drills 402 are set on the lifting end of the lifting assembly 410.

[0039] During the processing of the brake pad, when it is necessary to fix the brake pad placed on the rotating cylinder 220, there is a clear set of operating procedures. First, the brake pad is accurately placed in the corresponding placement groove 240 in the rotating cylinder 220 to provide preliminary positioning for the brake pad. Next, the rebound telescopic rod 234 is pressed into the middle plate 232. When the rotating cylinder 220 starts to rotate, the back pressure plate 238 will automatically retract the telescopic cylinder. This action causes the connecting rope 236 to extend, and the connecting elastic member 235 also extends accordingly. Under their joint action, the clamping block 233 extends. The clamping blocks 233 at both ends extend at the same time, tightly against the two ends of the brake pad, and firmly fix it on the rotating cylinder 220. When the brake pad is processed and needs to be removed, the rebound telescopic rod 234 is separated from the back pressure plate 238. Under the action of the rebound member 237, the rebound telescopic rod 234 extends, and the clamping block 233 is retracted into the middle plate 232 to make room for the next brake pad. This cyclic operation makes the fixing and removal of brake pads more convenient and quick, reducing operation time and labor costs. At the same time, the fixing effect is more stable, laying the foundation for providing stable processing accuracy. Under the premise of ensuring processing accuracy, the processing efficiency of brake pads is improved, making the production process more efficient and reliable.

[0040] In some embodiments, the fixing mechanism 200 also includes a cleaning assembly 260, which includes a cleaning plate 261, an air pump 262 and an air duct 263. The cleaning plate 261 is arranged on the rotating cylinder 220, and the placement groove 240 is divided into multiple parts in the placement groove 240 of the rotating cylinder 220. A material receiving groove 270 is opened on the workbench 100, and the air pump 262 is arranged on the workbench 100. One end of the air duct 263 is connected to the air pump 262, and the other end is connected to the fixed frame 210.

[0041] After the drilling process of a brake pad is completed, the debris generated during the processing will fall into the placement groove 240. Under the guidance of the cleaning plate 261, the debris will slide into the receiving groove 270. The remaining debris will be blown away by the high-pressure gas of the air guide pipe 263, reducing the possibility of residue. At the same time, during the blowing process, the brake pad that has not automatically detached from the rotating cylinder 220 can be blown off and fall into the receiving groove 270, thereby improving the reliability of the device; at the same time, it reduces the influence of the debris on subsequent processing and improves the processing accuracy of the device.

[0042] In some embodiments, a loading mechanism 300 is also provided on the workbench 100, and the loading mechanism 300 includes a pushing telescopic cylinder 301, a pushing plate 302, a lifting telescopic cylinder 303, a discharge plate 304, a guide plate 305 and a guide telescopic cylinder 307.

[0043] When loading is needed, the staff opens the workbench 100 in advance and places the unprocessed brake pads on the discharge plate 304, and multiple groups can be placed side by side at the same time; when loading, the guide telescopic cylinder 307 adjusts the height of the guide plate 305 and the distance between the rotating cylinder 220 to the loading distance of the brake pads, and the pushing telescopic cylinder 301 pushes multiple brake pads into the outside of the rotating cylinder 220 at the same time through the pushing plate 302, and then pushes it forward to make the pushing plate 302 abut against the middle plate 232, and the pushing plate 302 presses the rebound telescopic rod 234 into the middle plate 232, and then clamps and fixes the brake pads that have just been loaded, and then rotates the rotating cylinder 220; rotate to the next empty position to be loaded, retract the pushing plate 302, and the discharge plate 304 rises to lift a new layer of brake pads; the above cycle completes the loading, improves the loading efficiency of the brake pads, and enables loading and clamping to be carried out simultaneously, which greatly improves the processing efficiency.

[0044] In some embodiments, the lifting assembly 410 includes a lifting motor 411, a lifting screw 412 and a lifting plate 413. The lifting motor 411 is set on the mounting frame 401, one end of the lifting screw 412 is rotatably set on the mounting frame 401, the lifting screw 412 is transmission-connected to the driving end of the lifting motor 411, the lifting plate 413 is threadedly connected to the lifting screw 412, and the lifting plate 413 is slidably set on the mounting frame 401; the first drilling rig 402 is set on the lifting plate 413.

[0045] The drilling mechanism 400 also includes an adjustment component 420, which includes an adjustment frame 421, an adjustment screw 422, an adjustment block 423 and an adjustment motor 424. The adjustment frame 421 is set on the lifting plate 413, the adjustment screw 422 is rotatably set on the adjustment frame 421, the adjustment motor 424 is set on the adjustment frame 421, the adjustment screw 422 is transmission-connected to the adjustment motor 424, two adjustment blocks 423 are provided, the two adjustment blocks 423 are slidably set on the adjustment frame 421, and the adjustment block 423 is threadedly connected to the adjustment screw 422.

[0046] The drilling mechanism 400 also includes a plurality of second drilling rigs 403 and a propulsion assembly 430, wherein the propulsion assembly 430 includes a propulsion frame 431, a propulsion motor 432, a propulsion screw 433 and a propulsion slide 434, wherein the propulsion frame 431 is arranged on the workbench 100, the propulsion motor 432 is arranged on the propulsion frame 431, the propulsion screw 433 is rotatably arranged on the propulsion frame 431, one end of the propulsion screw 433 is transmission-connected to the propulsion motor 432, the propulsion slide 434 is slidably arranged on the propulsion frame 431, and the propulsion slide 434 is threadedly connected to the propulsion screw 433; the adjustment assembly 420 is also provided with a second group, the adjustment frame 421 in the adjustment assembly 420 of the second group is arranged on the propulsion slide 434, and all the second drilling rigs 403 are arranged on the adjustment block 423 in the adjustment assembly 420 of the second group.

[0047] When drilling is required, the first drill 402 or the second drill 403 that has been adjusted in position is used to drill holes in the brake pads through the lifting component 410 or the propulsion component 430, or the two brake pads on the top and the side are drilled at the same time, thereby improving the drilling efficiency; when the drilling angle needs to be adjusted, the drilling angle can be adjusted by rotating the rotating cylinder 220, thereby improving the operability of the processing; when the drilling distance or position needs to be adjusted, the adjustment block 423 is driven to move through the adjustment motor 424 of the adjustment component 420, so that the two relative first drills 402 or the second drills 403 are adjusted to each other at the same time, thereby improving the processing efficiency.

[0048] The implementation principle of a drilling machine for processing automobile brake pads in the embodiment of the present invention is as follows:

[0049] A plurality of support rods 250 are provided to realize multi-point support for the brake pad, which not only reduces the obstruction and influence on the drill bit during the drilling process, provides favorable support for the brake pad, improves the drilling accuracy, but also can adjust the position by sliding the support rod 250 when facing brake pads with different hole positions, thereby expanding the scope of application of the device. The fixing mechanism 200 performs well in fixing and removing the brake pad. After the brake pad is placed in the placement groove 240 in the rotating cylinder 220, the rebound telescopic rod 234 is pressed in, and the return pressure plate 238 shrinks the telescopic cylinder during rotation, driving the connecting rope 236 and the connecting elastic member 235 to extend, so that the clamping block 233 extends and presses against both ends of the brake pad to achieve fixation; when removing, the rebound telescopic rod 234 is separated from the return pressure plate 238, and the clamping block 233 retracts the middle plate 232 under the action of the rebound member 237, so as to facilitate the placement of the next brake pad. This cyclic operation makes the fixing and removal of the brake pad more convenient and stable, and improves the processing efficiency while providing stable processing accuracy. The cleaning component 260 can effectively handle the debris generated by processing. After drilling a brake pad, the debris falls into the placement groove 240, and slides into the receiving groove 270 under the guidance of the cleaning plate 261. The remaining debris can be blown away by the high-pressure gas of the air guide pipe 263, reducing the possibility of residue. It can also blow off the brake pad that has not automatically separated from the rotating cylinder 220 into the receiving groove 270, improving the reliability of the device, reducing the impact of debris on subsequent processing, and improving processing accuracy. The feeding mechanism 300 greatly improves the feeding efficiency. When feeding, the staff puts the unprocessed brake pads on the discharge plate 304 in advance, and multiple groups can be placed side by side at the same time. The material guide telescopic cylinder 307 adjusts the height of the material guide plate 305, and the material push telescopic cylinder 301 pushes multiple brake pads into the outside of the rotating cylinder 220 through the material push plate 302 and pushes them forward, so that the material push plate 302 abuts against the middle plate 232 and presses the rebound telescopic rod 234 to achieve clamping and fixing. After the rotating cylinder 220 rotates to the next empty position to be loaded, the material push plate 302 is retracted, and the material discharge plate 304 rises to lift a new layer of brake pads. In this cycle, loading and clamping are carried out simultaneously, greatly improving processing efficiency. The drilling mechanism 400 is efficient and flexible in drilling. Through the lifting component 410 or the propulsion component 430, the first drilling rig 402 or the second drilling rig 403 with adjustable position can be used to drill holes in the brake pads, and can also drill holes in the two brake pads on the top and the side at the same time; the rotating cylinder 220 can be rotated to adjust the drilling angle, thereby improving the processing operability; the adjustment motor 424 of the adjustment component 420 drives the adjustment block 423 to move, so that the relative first drilling rig 402 or the second drilling rig 403 can be adjusted in position at the same time, thereby further improving the processing efficiency.
