Technical Field

[0001] The invention relates to the technical field of drilling machines, and in particular to a drilling machine for machining a lower ball head of an automobile with a debris cleaning function. Background Art

[0002] The structure of the ball head is actually very simple. One end is a steel ball, and the other end is a "ball bowl". The "ball bowl" just wraps the steel ball, and the steel ball can rotate freely in the "ball bowl". In automobiles, ball heads are very common, such as the steering gear tie rod, the joint of the suspension arm, and the ball head mounting seat needs to be drilled using a drilling machine during the processing process to process the mounting holes on the ball head mounting seat. For example, patent publication number CN110090984A discloses a mounting hole drilling device for the ball head assembly of the lower arm body of an automobile. Through the joint action of an automatic drilling machine and a pushing mechanism, the processing accuracy is guaranteed and manpower is saved.

[0003] However, a large amount of debris will be generated during the drilling process, and due to the high-speed friction between the drill bit and the ball head mounting seat, the surface temperature of the debris is relatively high.

The closing cover, the movable cylinder and the fixed cylinder cooperate to protect the drilling position, avoid the debris generated by the drilling and the cutting fluid sprayed by the sprayer from splashing, and the area of ​​the closing cover is large, so the top of the movable cylinder is kept closed during the movement of the main shaft and the drill bit.

[0012] 2. In the present invention, cutting fluid is sprayed toward the drilling position by a sprayer, and cold air is blown toward the drilling position by a purge nozzle at the same time, so as to cool and clean the drilling position. The generated metal debris and cutting fluid are blown into the inside of the filter screen, and the driven gear ring and the filter screen are driven to rotate by a driving rack.

[0013] 3. In the present invention, the liquid collecting bucket and the filter screen can be raised and lowered by the lifting seat. As the liquid collecting bucket falls, the blocking rod blocks the side of the liquid collecting bucket away from the lifting seat, causing the liquid collecting bucket to tilt, so that the debris in the filter screen can be dumped out. At the same time, the lifting and lowering of the blocking rod can push the liquid collecting bucket and the filter screen to shake, thereby accelerating the efficiency of dumping the debris.

[0014] 4. In the present invention, air can be supplied to the interior of the air inlet pipe through the air supply pipe, and the corresponding air inlet pipe is controlled to be connected with the drive chamber through the three-way valve, so that air is taken in on one side of the drive plate to push the drive plate to move, and air is discharged from the other side of the drive plate through the air outlet pipe, so that the drive plate drives the movement of the drive rack.

At the same time, the metal debris in the filter can be purged to accelerate the separation of the metal debris and the cutting fluid.

[0015] 5. In the present invention, the workbench and the workpiece can be driven to rotate through the rotating ring, and the angle of the workpiece can be adjusted to meet different processing requirements. The workbench can be turned over through the rotating shaft to pour the debris on the surface of the workbench and the workpiece and the cutting fluid into the filter and the liquid collecting bucket.

[0016] 6. Therefore, compared with the ordinary drilling machine in the prior art, the present invention protects the drilling position by cooperating with the fixed cylinder, the movable cylinder, the closing cover and the filter screen to prevent the metal debris and cutting fluid generated by the drilling from splashing out, and the metal debris and cutting fluid are blown down to the inside of the filter screen by the purge nozzle. After the processing is completed, the workbench can be turned over by the rotating shaft to completely dump the debris on the workbench and the surface of the workpiece into the inside of the filter screen, and the air is supplied to the inside of the drive bin through the air supply pipe and the air intake pipe.

The cutting fluid is thrown into the collecting bucket and discharged through the drain pipe. At the same time, the air in the bin is driven into the collecting bucket through the air outlet pipe and the blow-down pipe, which assists in the separation of the cutting fluid and metal chips and the discharge of the cutting fluid. The collecting bucket and the filter screen are driven to fall through the lifting seat. The collecting bucket and the filter screen are tilted under the blocking effect of the blocking rod, so that the chips in the filter screen can be dumped out, reducing the damage of the surrounding environment by the metal chips and the cutting fluid.

Air is supplied to the interior of the driving compartment 701 through the air supply pipe 8 and the air inlet pipe 705, and the two are controlled by a three-way valve. The air inlet pipe 705 supplies air to the driving bin 701 in turn, realizing the reciprocating movement of the driving plate 702 and the driving rack 704, driving the filter screen 302 to rotate, and separating the metal debris and the cutting fluid under the action of centrifugal force, and the cutting fluid is thrown into the interior of the liquid collecting bucket 301 and discharged through the drain pipe 303. At the same time, the air in the driving bin 701 is sent into the interior of the liquid collecting bucket 301 through the air outlet pipe 706 and the blow-off pipe 801, assisting in the separation of the cutting fluid and the metal debris and the discharge of the cutting fluid, and driving the liquid collecting bucket 301 and the filter screen 302 to fall through the lifting seat 401, and the liquid collecting bucket 301 and the filter screen 302 are tilted under the blocking action of the blocking rod 402, so that the debris in the filter screen 302 can be dumped out, reducing the damage of the metal debris and the cutting fluid to the surrounding environment, and the metal debris and the cutting fluid can be processed separately.

[0022] like Figures 1 to 6As shown, the protection mechanism is used to comprehensively protect the drilling position, and the protection mechanism includes a protection cylinder and a closing cover 101. The protection cylinder is arranged on the bed 1, and the workbench 2 is arranged inside the protection cylinder. The protection cylinder is a telescopic structure, and the closing cover 101 is arranged on the spindle 3. The closing cover 101 is in contact with the top of the protection cylinder, and the sprayer 5 is arranged on the closing cover 101. The workpiece is clamped on the workbench 2, and the spindle 3 drives the drill bit 4 to lift and move, and the drill bit 4 drills the workpiece. The sprayer 5 sprays cutting fluid to the drilling position to cool the drilling position, and the top of the protection cylinder is sealed by the closing cover 101 to reduce the splashing of cutting fluid and metal debris generated by drilling. The closing cover 101 has a large area, and when the spindle 3 and the drill bit 4 move to drill different positions of the workpiece, the closing cover 101 can always close the top of the protection cylinder to ensure the blocking effect of metal debris and cutting fluid.

[0023] like Figures 5 and 6 As shown, in order to cooperate with the lifting and drilling work of the main shaft 3 and the drill bit 4, the protective cylinder includes a fixed cylinder 201, a movable cylinder 202, a fixed plate 203, a movable plate 204 and a slide bar 205. The fixed cylinder 201 is arranged on the bed 1, the workbench 2 is arranged inside the fixed cylinder 201, the movable cylinder 202 is slidably arranged outside the fixed cylinder 201, the fixed plate 203 is arranged outside the fixed cylinder 201, the movable plate 204 is arranged outside the movable cylinder 202, a supporting spring 206 is arranged between the movable plate 204 and the fixed plate 203, the closing cover 101 is in contact with the top end of the movable plate 204, the slide bar 205 is arranged on the fixed plate 203, and the movable plate 204 and the slide bar 205 are arranged on the fixed plate 203. The rod 205 is in a sliding fit, and the total height of the protective cylinder can be adjusted by the sliding fit of the fixed cylinder 201 and the movable cylinder 202. The closing cover 101 is pressed against the top of the movable cylinder 202, and the main shaft 3 drives the drill bit 4 to descend for drilling, and at the same time drives the closing cover 101 to descend. The closing cover 101 can drive the movable cylinder 202 to descend and compress the supporting spring 206. When the main shaft 3 drives the drill bit 4 and the closing cover 101 to rise, the movable cylinder 202 is pressed against the bottom end of the closing cover 101 under the action of the supporting spring 206, so that the closing cover 101 always forms a closed space with the protective cylinder during the drilling process, and metal debris and cutting fluid are more fully sealed.

[0024] like Figure 4As shown, the filtering mechanism is used to filter metal debris, and the filtering mechanism includes a liquid collecting bucket 301 and a filter screen 302. The liquid collecting bucket 301 is arranged below the protective cylinder, and the bottom of the liquid collecting bucket 301 is connected to a drain pipe 303. The filter screen 302 can be rotatably arranged inside the liquid collecting bucket 301. Under the action of centrifugal force, the metal debris and the cutting fluid are separated. The cutting fluid flushes the drilling position, so that the metal debris and the cutting fluid fall into the liquid collecting bucket 301 and the filter screen 302. The filter screen 302 separates the metal debris and the cutting fluid. At the same time, the centrifugal force formed by the rotation of the filter screen 302 promotes the throwing out of the cutting fluid. The cutting fluid falls into the liquid collecting bucket 301 and is discharged through the drain pipe 303 for collection, and the metal debris is retained in the filter screen 302 for subsequent treatment.

[0025] like Figure 3 As shown, the purge pipe 6 is arranged on the closing cover 101, and the purge pipe 6 is connected to a plurality of purge nozzles 7, and the purge pipe 6 is connected to an air supply pipe 8, and the air supply pipe 8 is connected to an external air supply device, and the external air supply device box supplies air to the purge pipe 6 and the purge nozzle 7, and the purge nozzle 7 purges the drilling position, cools down the drilling position, and blows metal debris on the surface of the workpiece into the inside of the filter 302.

[0026] like Figure 4As shown, the liquid collecting bucket 301 can be separated from the protective cylinder, and the dumping mechanism is used to dump the liquid collecting bucket 301 to dump out the metal debris inside the filter screen 302. The dumping mechanism includes a lifting seat 401 and a blocking rod 402. The lifting seat 401 can be lifted and arranged on the bed 1. The bed 1 is provided with an electric cylinder 403. The lifting seat 401 is arranged at the output end of the electric cylinder 403. The liquid collecting bucket 301 is rotatably arranged on the lifting seat 401 through a rotating rod 404. When the liquid collecting bucket 301 is in a horizontal state, the bottom end of the rotating rod 404 contacts the top end of the lifting seat 401, and the blocking rod 402 can be lifted and arranged on the bed 1 The bed body 1 is provided with an electric cylinder 2 405, and a rotating seat 406 is provided at the output end of the electric cylinder 2 405. The stopper 402 is rotatably provided on the rotating seat 406, and the stopper 402 is in contact with the bottom end of the liquid collecting bucket 301. When the liquid collecting bucket 301 is above the stopper 402, the liquid collecting bucket 301 is in a horizontal state. The lifting seat 401 and the liquid collecting bucket 301 can be driven to lift and lower by the electric cylinder 1 403. A limiting ring 407 is provided at the bottom end of the fixed cylinder 201. The filter screen 302 and the limiting ring 407 are in sealing and sliding cooperation. When the liquid collecting bucket 301 and the bottom of the fixed cylinder 201 are tightly attached, the filter screen 302 and the limiting ring 407 are in sealing and sliding cooperation. 07, at this time, the rotating rod 404 is in a horizontal state, and the lifting seat 401 blocks the rotating rod 404 to keep the liquid collecting bucket 301 and the filter screen 302 in a horizontal state. At the same time, the electric cylinder 405 drives the blocking rod 402 to rise to a state close to the bottom of the liquid collecting bucket 301, supports and limits the liquid collecting bucket 301, and ensures the stability of the liquid collecting bucket 301 and the filter screen 302. When the metal debris in the filter screen 302 needs to be dumped out, the electric cylinder 405 drives the blocking rod 402 to descend a certain distance, and then the electric cylinder 1 403 drives the lifting seat 401 and the liquid collecting bucket 301 to descend. Initially, the lifting seat 401 and the filter screen 302 are in a horizontal state. Under the blocking effect of the seat 401 on the rotating rod 404, the liquid collecting bucket 301 is in a horizontal state. After descending a certain distance, the side of the liquid collecting bucket 301 away from the lifting seat 401 contacts the blocking rod 402, and the lifting seat 401 continues to drive the liquid collecting bucket 301 to descend. Under the blocking effect of the blocking rod 402 on the liquid collecting bucket 301, the rotating rod 404 rotates around the rotating seat 406, and the end close to the lifting seat 401 descends, which can dump out the metal debris in the filter screen 302. At the same time, the blocking rod 402 is driven to rise and fall reciprocally by the electric cylinder 405, which can push the liquid collecting bucket 301 and the filter screen 302 to shake, thereby promoting the falling of the metal debris.

Under the action of the fixed inner gear ring 503, the driving gear 502 is made to revolve along the fixed inner gear ring 503 during its self-rotation, thereby driving the rotating ring 501 and the workbench 2 to rotate, so as to adjust the angle of the workpiece to meet different drilling requirements.

[0028] like Figures 5 and 6 As shown, in order to realize the flipping of the workbench 2, the metal scraps on the workbench 2 are dumped down. The workbench 2 is arranged on the rotating ring 501 through a flipping assembly, which is used to dump the metal scraps and cutting fluid on the workbench 2.

The two sides of the drive chamber 701 are connected through the one-way valve 707, and the corresponding air inlet pipe 705 is controlled to be connected with the drive chamber 701 through the three-way valve. The air inlet pipe 705 supplies air to the interior of the drive chamber 701, so that the pressure on one side of the drive plate 702 increases, and the drive plate 702 is pushed to move toward the side of the unconnected air inlet pipe 705. As the drive plate 702 moves, the air outlet pipe 706 in the moving direction of the drive plate 702 discharges air outward. After the drive plate 702 moves to one side of the drive chamber 701, the three-way valve controls the other air inlet pipe 705 to be connected with the drive chamber 701, pushing the drive plate 702 to move in the opposite direction, and the other air outlet pipe 706 exhausts air outward, thereby realizing the reciprocating movement of the drive plate 702, thereby driving the drive rack 704 to move back and forth, driving the driven gear ring 703 and the filter screen 302 to rotate back and forth, and throwing the cutting fluid out from the inside of the filter screen 302.

[0030] like Figure 7 As shown, in order to assist the cutting fluid in the liquid collecting bucket 301 to be discharged, an auxiliary blowing mechanism is also included.

At the same time, part of the air is used to purge the filter screen 302 to reduce the blockage of the filter screen 302 caused by metal debris, and at the same time promote the separation of the cutting fluid and metal debris.

[0031] The working principle or use process of the drilling machine for processing the lower ball head of the automobile with the chip cleaning function is as follows: Initially, the spindle 3 and the drill bit 4 are at a higher position, the closing cover 101 is away from the moving cylinder 202, the workpiece is clamped on the workbench 2, and then the spindle 3 drives the drill bit 4 to descend, the closing cover 101 is pressed against the top of the moving cylinder 202, and the drill bit 4 is controlled to perform drilling processing on the workpiece; During the machining process, the cutting fluid is sprayed toward the drilling position, the purge nozzle 7 blows cold air toward the drilling position, and the fixed cylinder 201, the movable cylinder 202, the closing cover 101 and the filter screen 302 cooperate to protect the drilling position to prevent metal debris and cutting fluid generated by drilling from splashing out; After the processing is completed, the motor 2 604 drives the rotating shaft 601 to rotate and turn the workbench 2 over, and the workbench 2 and the debris on the surface of the workpiece are completely dumped into the filter 302. The air supply pipe 8 and the air inlet pipe 705 supply air to the inside of the driving bin 701. The three-way valve allows the two air inlet pipes 705 to supply air to the driving bin 701 in turn. The driving plate 702 and the driving rack 704 move back and forth, driving the filter 302 to rotate. Under the action of centrifugal force, the metal debris and the cutting fluid are separated, and the cutting fluid is thrown into the inside of the liquid collecting bucket 301 and discharged through the drain pipe 303. At the same time, the air in the drive bin 701 is sent into the liquid collecting bucket 301 through the air outlet pipe 706 and the blow-down pipe 801, which assists in the separation of the cutting fluid and metal debris and the discharge of the cutting fluid. The electric cylinder 403 drives the lifting seat 401 and the liquid collecting bucket 301 to fall. Under the blocking effect of the blocking rod 402, the liquid collecting bucket 301 and the filter screen 302 are tilted to dump the debris in the filter screen 302. Then the spindle 3 drives the drill bit 4 and the closing cover 101 to rise, and the workpiece after drilling can be taken out.
