Technical Field

[0001] This invention relates to the field of drilling positioning technology, specifically to a positioning device for drilling hardware parts. Background Technology

[0002] Hardware refers to tools made from metals such as gold, silver, copper, iron, and tin through processing and casting. Hardware requires many processing steps in its production, such as cutting, drilling, polishing, electroplating, and cleaning. The equipment used in the hardware processing can be collectively referred to as hardware processing equipment.

[0003] In the existing technology, when drilling hardware parts, the existing drilling equipment has relatively simple functions. It requires the operator to feed the hardware parts in, confirm the processing position, and then clamp and fix them. After the drilling is completed, the hardware parts need to be taken out and repeatedly positioned and clamped. The processing process is relatively cumbersome and affects the processing efficiency.

[0015] Preferably, a cross slide is fixedly connected to the bottom of the mounting plate, a spindle is fixedly connected to the output end of the cross slide, and a drill rod is fixedly connected to the end face of the spindle.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, when drilling hardware parts, the hardware parts are displaced by the running conveyor belt. After the hydraulic rod is activated and extended, it can drive the push plate to move the hardware parts out of the discharge chute. After the hydraulic rod is extended, the electric telescopic rod extends and drives the inclined block to follow the displacement. The second roller is pushed by the inclined surface of the inclined block, which causes the clamping plates on both sides to move synchronously towards the hardware parts, completing the centering and clamping positioning of the hardware parts. Next, the electric telescopic rod is activated and the main shaft is started. The high-speed rotating drill rod contacts the surface of the hardware parts to complete the drilling. After the drilling of one hardware part is completed, the drilled hardware parts are sent out by the coordinated operation of the electric telescopic rod, hydraulic rod and conveyor belt. Then the next hardware part is fed in. The hardware parts can continue to be automatically pushed into place, clamped and positioned, drilled and discharged, so that the device has a high degree of automation and effectively improves the processing efficiency.

[0017] 2. In this invention, while the electric telescopic rod repeatedly moves up and down to perform multi-position drilling on the hardware, the piston pushes down inside the sleeve during the downward movement of the mounting plate. This pushes outwards the air inside the sleeve, and the airflow is ejected from the nozzle through the connection between the cone and the connecting pipe. The nozzle's outlet position corresponds to the surface position of the support plate, so the airflow can reach the bottom surface of the hardware. During the drilling process, the electric telescopic rod repeatedly extends and retracts to perform multi-position drilling, and the resulting airflow cleans the bottom surface of the hardware, blowing off any debris adhering to it. The metal debris adhering to the bottom surface of the hardware wears down the conveyor belt during transport, thus extending the lifespan of the device.

[0018] 3. In this invention, when the hardware part is conveyed to the limit switch position, the position corresponding to the limit switch is the infeed / outfeed positioning position of the hardware part. At this time, the hardware part touches the lever position of the limit switch. After the limit switch is triggered, it will control the conveyor belt to stop running. At this time, the hardware part is conveyed into place. After the guide rail has completely moved into place, the hardware part will be pushed to the position of fitting the baffle surface. At this time, through the setting of the trigger switch, when the hardware part moves to fit the baffle surface, the trigger switch will be pressed and triggered. At this time, the hardware part is conveyed into place. Through the combined use of the limit switch and the trigger switch, the displacement position of the hardware part can be positioned to confirm that the hardware part is in the correct position for each processing step, thereby improving the stability of the device operation.

The cross-section of the groove 402 is smaller than that of the workpiece. A side groove 403 is formed at the top of the support plate 401, communicating with the chip removal groove 402. An air outlet 404 is fixedly connected to the inner surface of the side groove 403. A connecting pipe 405 is fixedly connected to the bottom of the support plate 401, with one end face of the connecting pipe 405 penetrating the support plate 401 and communicating with the air outlet 404. Springs 504 are symmetrically fixedly connected to the outer surface of the clamping seat 501. A clamping plate 503 is fixedly connected between the end faces of the two springs 504, and the two clamping plates 503 are located outside the stop 406. A movable rod 502 is symmetrically fixedly connected to the outer surface of the clamping plate 503 near the springs 504. The movable rod 502 is slidably connected to the clamping seat 501. The movable rod 502 is located inside the spring 504. A second bracket 505 is fixedly connected to the outer surface of the clamping plate 503 near the clamping seat 501. A second roller 506 is rotatably connected to the inner surface of the second bracket 505. A hydraulic rod 602 is fixedly connected to the top of the drilling frame 601. The output end of the hydraulic rod 602 passes through the drilling frame 601 and extends to the lower side. A movable plate 603 is fixedly connected to the output end of the hydraulic rod 602. Multiple extension rods 604 are fixedly connected to the bottom of the movable plate 603. A guide rail 605 is fixedly connected between the end faces of the multiple extension rods 604. The outer surface of the first roller 209 is... The inner surface of the guide rail 605 is slidably connected. An electric telescopic rod 606 is fixedly connected to the bottom of the moving plate 603. A mounting plate 607 is fixedly connected to the lower end face of the electric telescopic rod 606. A wedge block 608 is symmetrically fixedly connected to the bottom of the mounting plate 607, positioned above the second roller 506. Slots 609 are symmetrically opened on the top of the mounting plate 607, located on the side of the wedge block 608. The cross-section of the slot 609 is larger than the cross-section of the second bracket 505. A cross slide 610 is fixedly connected to the bottom of the mounting plate 607. A spindle 611 is fixedly connected to the output end of the cross slide 610, and a drill rod 612 is fixedly connected to the end face of the spindle 611.

[0023] In this invention, during the drilling process of the hardware parts, the hardware parts are displaced by the running belt 203. After the hydraulic rod 602 is activated and extended, it can drive the guide rail 605 to move downward. The first roller 209 is affected by the inclined surface of the guide rail 605, causing the first roller 209 to be pushed towards the fixed seat 3. At this time, the push plate 206 can fit against the surface of the hardware parts. After the push plate 206 fits, the vacuum suction cup 207 is activated, which can perform vacuum adsorption on the surface of the hardware parts. The push plate 206 will push the hardware parts out of the discharge trough 204. After the guide rail 605 has completely moved into place, the hardware parts will be pushed onto the fitting bracket. At surface position 406, after the hydraulic rod 602 extends, the electric telescopic rod 606 extends, causing the mounting plate 607 and the wedge block 608 to move accordingly. The second roller 506 is pushed by the inclined surface of the wedge block 608, causing the second rollers 506 on both sides to move synchronously towards the hardware. At this time, the clamping plates 503 on both sides move synchronously towards the hardware, thus completing the centering and clamping positioning of the hardware. After the mounting plate 607 and the wedge block 608 move down and push the clamping plates 503 into place to complete the clamping of the hardware, the drill rod 612 is now above the hardware. Next, the electric telescopic rod 606 continues to extend, and at the same time, the spindle 611 starts to drive the drill rod 612 to rotate. As the mounting plate 607 continues to move downwards, the high-speed rotating drill rod 612 contacts the surface of the hardware to complete the drilling. After drilling one position on the hardware, the electric telescopic rod 606 retracts, causing the mounting plate 607 to move upwards and return to the clamping position. Subsequently, the positions of the spindle 611 and the drill rod 612 can be adjusted arbitrarily by the operation of the cross slide 610. After the drill rod 612 is adjusted to the next drilling position, the electric telescopic rod 606 is extended again, allowing continuous drilling of the hardware. After drilling one hardware part is completed, the electric telescopic rod 606 retracts, causing the mounting plate 607 to move upwards and return to its original position. At this time, the wedge block 608 moves upwards and disengages. The second roller 506 is supported by the spring 504, which can drive the clamping plate 503 to return to its initial position. Then, the hydraulic rod 602 is activated to retract and return to its initial position. At this time, the guide rail 605 moves upward and returns to its initial position. The upward movement of the guide rail 605 can drive the push plate 206 to return to its initial position. Since the vacuum suction cup 207 is in a state of adsorption on the hardware, the push plate 206 will pull the hardware back to the surface of the conveyor belt 203. At this time, the vacuum suction cup 207 closes, and the conveyor belt 203 runs to send out the hardware. Then, the next hardware is fed in, and the automatic pushing, clamping, drilling, and unloading of hardware can continue.

[0024] Example 2: Figure 5 and Figure 6As shown, a chip removal groove 402 is provided on the top of the support plate 401. The chip removal groove 402 is located between the baffle 406 and the discharge groove 204. The cross-section of the chip removal groove 402 is smaller than that of the workpiece. A side groove 403 is provided on the top of the support plate 401. The side groove 403 is in communication with the chip removal groove 402. An air outlet 404 is fixedly connected to the inner surface of the side groove 403. A connecting pipe 405 is fixedly connected to the bottom of the support plate 401. One end face of the connecting pipe 405 passes through the support plate 401 and communicates with the air outlet 404. A cone head 408 is fixedly connected to the top of the support plate 401. A sleeve 409 is fixedly connected to the top of the cone head 408. A piston 410 is movably connected to the inner surface of the sleeve 409. A push rod 411 is fixedly connected to the top of the piston 410. A connecting plate 412 is fixedly connected to the upper end face of the push rod 411. The other end face of the connecting pipe 405 passes through the support plate 401 and communicates with the cone head 408.

[0025] In this invention, while the electric telescopic rod 606 repeatedly moves up and down to perform multi-position drilling on the hardware, the piston 410 pushes down inside the sleeve 409 along the downward path of the mounting plate 607. This push pushes out the air inside the sleeve 409, and the airflow is ejected from the air outlet 404 through the connection between the cone 408 and the connecting pipe 405. The air outlet 404 corresponds to the surface position of the support plate 401, so the airflow can reach the bottom surface of the hardware. During the drilling process, the electric telescopic rod 606 repeatedly extends and retracts to perform multi-position drilling, and the resulting airflow cleans the bottom surface of the hardware, blowing off any debris adhering to it. The metal debris adhering to the bottom surface of the hardware wears down the conveyor belt 203 during transport, thus extending the lifespan of the device.

[0026] Example 3: Figure 3 , Figure 5 and Figure 6 As shown, a limit switch 210 is fixedly connected to the top of the frame 202. The limit switch 210 is located on the side of the push plate 206. The limit switch 210 is electrically connected to the conveyor belt 203. A clearance groove is opened on the outer surface of the baffle 406 near the frame 202. A trigger switch 407 is fixedly connected to the bottom of the clearance groove. The trigger switch 407 is larger than the thickness of the clearance groove.

[0027] The invention operates as follows: when the hardware part is conveyed to the position of the limit switch 210, the position corresponding to the limit switch 210 is the infeed / outfeed positioning position of the hardware part. At this time, the hardware part touches the lever position of the limit switch 210. After the limit switch 210 is triggered, it controls the conveyor belt 203 to stop running, and the hardware part is conveyed into place. After the guide rail 605 has completely moved into place, the hardware part is pushed to the surface of the retainer 406. At this time, through the setting of the trigger switch 407, when the hardware part moves to the surface of the retainer 406, the trigger switch 407 is pressed and triggered, and the hardware part is conveyed into place. Through the cooperation of the limit switch 210 and the trigger switch 407, the displacement position of the hardware part can be positioned, confirming that the hardware part is in the correct position for each processing step, thus improving the stability of the device operation.

[0028] The overall effect and working principle of the mechanism are as follows: When drilling hardware parts, the hardware parts are conveyed through the conveying component 2. While the conveying component 2 is conveying the hardware parts, the supporting component 4, clamping component 5, and drilling component 6 work together to achieve automatic pushing, clamping, drilling, and unloading of the hardware parts. The hardware parts are displaced by the conveyor belt 203 during conveying. When the hardware parts reach the position of the limit switch 210, the limit switch 210... The position refers to the feeding and unloading positioning position of the hardware. At this time, the hardware touches the lever position of the limit switch 210. After the limit switch 210 is triggered, it will control the conveyor belt 203 to stop running. At this time, the hardware is delivered into position. Next, the hydraulic rod 602 is activated to extend. After the hydraulic rod 602 extends, it can drive the moving plate 603 to move down. The moving plate 603 can drive the guide rail 605 to move down through the extension rod 604. At this time, the guide rail 605 moves down and pushes the first roller 209. The first roller 209 is guided. The inclined surface of track 605 causes the first roller 209 to be pushed towards the fixed seat 3. The first roller 209, connected to the first bracket 208, then drives the push plate 206 to move. The push plate 206 then comes into contact with the surface of the hardware. After the push plate 206 comes into contact, the vacuum suction cup 207 is activated, performing vacuum suction on the surface of the hardware. As the moving plate 603 continues to move downwards, the surface of the conveyor belt 203 becomes flush with the surface of the support plate 401. The push plate 206 then pushes the hardware from the outlet... After the material is removed from the trough 204 and the guide rail 605 has fully moved into place, the hardware will be pushed to the position of the surface of the retaining bracket 406. At this time, the trigger switch 407 will be pressed and triggered when the hardware moves to the surface of the retaining bracket 406, indicating that the surface hardware has been delivered into place. Currently, the hydraulic rod 602 is in the extended state. When the moving plate 603 moves downward, it can drive the mounting plate 607 to move downward through the connection of the electric telescopic rod 606. That is, at this time, the working position of the mounting plate 607 is at a lower position. (Refer to...) Figure 5As shown, after the hydraulic rod 602 extends, the mounting plate 607 will move the inclined block 608 below it to a position close to the second roller 506. After the hydraulic rod 602 completes its extension, the hardware is pushed into place. Next, the hardware is clamped and drilled by the operation of the electric telescopic rod 606 and the cross slide 610. After the electric telescopic rod 606 extends, it can drive the mounting plate 607 and the inclined block 608 to move accordingly. When the inclined block 608 moves down, it will contact the second roller 506 below. The second roller 506 will be pushed by the inclined surface of the inclined block 608, causing... The second rollers 506 on both sides move synchronously towards the hardware. The second rollers 506, connected to the second bracket 505, drive the clamping plates 503 to move accordingly. At this time, the clamping plates 503 on both sides move synchronously towards the hardware, thus completing the centered clamping and positioning of the hardware. At this point, the hardware is positioned with one side pressed against the stop 406, and the other two sides clamped by the clamping plates 503, making its position relatively stable. After the mounting plate 607 and the inclined block 608 move down, pushing the clamping plates 503 into place to complete the clamping of the hardware, the drill rod 612 is now positioned above the hardware. The next step continues... The electric telescopic rod 606 extends, and simultaneously the spindle 611 drives the drill rod 612 to rotate. As the mounting plate 607 continues to move downwards, the high-speed rotating drill rod 612 contacts the surface of the hardware to complete the drilling. At the same time, the second roller 506 moves along the inclined block 608 to the slot 609. At this point, the second bracket 505 and the second roller 506 pass through the slot 609, thus securing the second bracket 505 within the slot 609. After the inclined block 608 pushes the second roller 506 to the clamping position, the mounting plate 607 continues to move downwards, and the second bracket 505 is locked in place. Since the rod cannot move left or right, it can always maintain the clamping state of the hardware. After drilling a hole in one position of the hardware, the electric telescopic rod 606 retracts, causing the mounting plate 607 to move upward and reset to the clamping position. Then, the position of the spindle 611 and the drill rod 612 can be adjusted arbitrarily by the operation of the cross slide 610. After the drill rod 612 is adjusted to the next drilling position, the electric telescopic rod 606 is activated to extend, so that the hardware can be continuously drilled. While the electric telescopic rod 606 repeatedly moves up and down to drill holes in the hardware in multiple positions, refer to... Figure 5As shown, the mounting plate 607 and the connecting plate 412 are connected. Therefore, when the mounting plate 607 moves up and down, the piston 410 can be driven to move along through the connection of the connecting plate 412 and the push rod 411. In the downward movement path of the mounting plate 607, the piston 410 will push down inside the sleeve 409. When pushing down, it will push the air inside the sleeve 409 outward. At this time, the airflow will be sprayed out from the air outlet 404 through the connection of the cone head 408 and the connecting pipe 405. The air outlet position of the air outlet 404 corresponds to the surface position of the support plate 401. Therefore, the airflow blown out at this time can act on the bottom surface of the hardware. At this time, during the drilling process, the electric telescopic rod 606 repeatedly extends and retracts to perform multi-position drilling. The airflow generated can clean the bottom surface of the hardware, causing the debris attached to the bottom surface of the hardware to be blown off. The metal debris attached to the bottom surface of the hardware causes wear on the conveyor belt 203 during conveying, which helps to extend the service life of the device. Meanwhile, the air blowing from the nozzle 404 utilizes the kinetic energy conversion generated by the device's own operation, reducing energy consumption and playing a role in energy conservation and environmental protection. After completing the drilling of a hardware part, the electric telescopic rod 606 is activated to retract, driving the mounting plate 607 to move upward and reset. At this time, the inclined block 608 moves upward and disengages from the support of the second roller 506. The rebound force of the spring 504 can drive the clamping plate 503 to reset to its initial position. Then, the hydraulic rod 602 is activated to retract and reset. At this time, the guide rail 605 moves upward and resets. Through the upward reset of the guide rail 605, the push plate 206 can be reset. At this time, since the vacuum suction cup 207 is in an adsorption state on the hardware part, the push plate 206 will pull the hardware part back to the surface of the conveyor belt 203. At this time, the vacuum suction cup 207 closes, and the conveyor belt 203 runs to send out the hardware part. Then, the next hardware part is fed in, and the automatic pushing, clamping, drilling, and unloading steps of the hardware parts can continue.
