Description

Technical Field

[0001] This invention relates to the field of fastener processing equipment, and in particular to a fastener polishing machine feeding mechanism and a polishing machine equipped with the feeding mechanism. Background Technology

[0002] Fasteners often require polishing during processing. Chinese Patent Application No. 202220751869.X discloses a surface polishing device for screw fasteners, including a base. The top of the base is equipped with a pusher assembly, a feeding assembly, and a polishing assembly that mate with an internal thread cap. The pusher assembly includes a rectangular support fixed to the top of the base, a rectangular concave groove fixed to the top of the rectangular support, a transverse lead screw driven within the rectangular concave groove, a fixed seat connected to the transverse lead screw via a lead screw nut, and a fixed base... The fixed base has a horizontal push rod at the top and a servo geared motor fixedly installed on the left side of the rectangular concave groove and connected to the input end of the horizontal lead screw; the feeding assembly includes support legs arranged at equal intervals and fixedly installed on the top of the base and a horizontal feeding pipe fixedly installed on the top of the support legs; the polishing assembly has two components, and each polishing assembly includes a motor support fixedly installed on the top of the base, a polishing motor fixedly installed on the top of the motor support, a polishing wheel fixedly connected to the output shaft of the polishing motor, and a protective cover fixedly installed on the polishing motor and sleeved on the outer side of the polishing wheel.

[0003] The aforementioned surface polishing device for screw fasteners stacks internal thread caps inside a transverse feeding pipe. A servo reduction motor drives a transverse lead screw to rotate, causing the fixed base to move to the left. This allows the transverse push rod to also move to the left, pushing the internal thread caps. The internal thread caps are fed to the positions of the two polishing cuts. The two polishing wheels rotate in opposite directions and are in contact with the stacked internal thread caps. The rotation of the two polishing wheels drives the stacked internal thread caps to rotate, polishing the outer surface of the internal thread caps. Under the action of the transverse push rod, the internal thread caps can move and rotate simultaneously, making polishing convenient and effective. This device achieves continuous feeding, automated discharge, and automated polishing of internal thread caps.

[0004] However, with the aforementioned surface polishing device for screws and fasteners, when the fasteners in the transverse feeding pipe are polished and new fasteners need to be stacked and placed into the transverse feeding pipe, the machine needs to be stopped for feeding. This requires the operator to turn the polishing machine on and off repeatedly, making the operation less smooth and more cumbersome. Summary of the Invention

[0005] In order to improve production flow by eliminating the need for machine downtime during the feeding process, this application provides a feeding mechanism for a fastener polishing machine.

[0006] The fastener polishing machine feeding mechanism provided in this application adopts the following technical solution:

[0007] A fastener polishing machine feeding mechanism includes a base and a sliding seat slidably disposed on the base. The sliding seat is provided with a push rod. The base is provided with a drive mechanism for driving the sliding seat to move back and forth. The base is provided with a support platform. The support platform is provided with a feeding slider that slides laterally relative to the push rod. The feeding slider is provided with a plurality of feeding slots for horizontally stacking fasteners. The two ends of the feeding slots are respectively connected to the outside. The feeding slots are arranged along the sliding direction of the feeding slider. A linkage mechanism is provided between the sliding seat and the feeding slider to cause the feeding slider to move at intervals for feeding as the sliding seat moves back.

[0008] By adopting the above technical solution, before processing, the operator can pre-place fasteners in each loading slot. The drive mechanism can drive the sliding seat to move back and forth, so that the fasteners in one of the loading slots can be conveyed forward to the polishing machine for polishing by the push rod. When the drive mechanism drives the sliding seat to move back, the linkage mechanism will drive the loading slider to move, so that the next loading slot is aligned with the push rod. The operator can then place fasteners in the empty loading slot. This structure can load materials without stopping the machine, making the processing more streamlined.

[0009] Optionally, the linkage mechanism includes a drive rod and a first spring. The bottom of the feeding slider is provided with several first positioning grooves corresponding one-to-one with the feeding slots. The base is provided with a sliding groove. One end of the drive rod is slidably connected to the sliding groove, and the other end is located in any of the first positioning grooves. The support platform is provided with a channel for the drive rod to slide back and forth. The sliding direction of the drive rod is the same as that of the sliding seat. One end of the first spring is connected to the drive rod, and the other end is connected to the inner wall of the sliding groove. The sliding seat is provided with a connecting rod. The connecting rod is provided with a hook that pulls the drive rod as the sliding seat moves back. The bottom of the feeding slider is provided with a first guide groove that guides the drive rod into the next first positioning groove as it slides. The bottom of the feeding slider is provided with a reset groove that guides the drive rod from the tail first guide groove to the front first guide groove as it slides. The reset groove is connected to the first guide grooves on the front and rear sides respectively.

[0010] By adopting the above technical solution, when the sliding seat moves back under the action of the drive mechanism, it will also drive the connecting rod and the hook to move back together. When the hook touches the drive rod, it will drive the drive rod to move together. The drive rod enters the first guide groove. When the sliding seat moves forward under the action of the drive mechanism, the hook and the drive rod disengage. The drive rod moves back under the action of the first spring and enters the next first positioning groove under the action of the first guide groove. When the drive rod moves to the tail first positioning groove, it can move back to the front first positioning groove through the reset groove. This cycle can be repeated. Since the first positioning groove corresponds to the feeding groove one by one, the next full feeding groove can be automatically moved to the pushing position without manual pushing of the feeding slider, making the operation more convenient and simple.

[0011] Optionally, the reset groove includes a plurality of second positioning grooves that correspond one-to-one with the first positioning groove. A second guide groove is provided between two adjacent second positioning grooves to guide the drive rod into the next second positioning groove as it slides. The first guide groove and the second guide groove have opposite guiding directions. The bottom of the feeding slider is provided with a first connecting groove to guide the drive rod from the tail end first positioning groove into the front end second positioning groove. The bottom of the feeding slider is provided with a second connecting groove to guide the drive rod from the tail end second positioning groove into the front end first positioning groove.

[0012] By adopting the above technical solution, after the drive rod moves to the first positioning groove at the tail end, it can move to the second positioning groove at the front end through the first connecting groove. Then, the drive rod can be guided to the next second positioning groove through the second guide groove. When the drive rod moves to the second positioning groove at the tail end, it can be guided to the first positioning groove at the front end through the second connecting groove. This cycle can be repeated continuously. This structure allows the feeding slider to feed materials during the left and right sliding process without having to reset to the initial position, thereby improving processing efficiency.

[0013] Optionally, the first guide groove includes a first inclined slide groove communicating with the previous first positioning groove and a second inclined slide groove communicating with the next first positioning groove. The first inclined slide groove is inclined to the left from the direction from the loading slider to the sliding seat, and the second inclined slide groove is inclined to the right from the direction from the loading slider to the sliding seat. The first inclined slide groove and the second inclined slide groove form a first limiting groove. The first limiting groove is located on one side of the second inclined slide groove, and the central axis of the first positioning groove passes through the inclined surface of the first inclined slide groove.

[0014] By adopting the above technical solution, during the retraction process of the sliding seat, when the force of the hook acts on the driving rod, the driving rod moves and first enters the first inclined slide groove from the first positioning groove, and then gets stuck in the first limiting groove along the first inclined slide groove. Since the first limiting groove is located on one side of the second inclined slide groove, after the hook disengages from the driving rod, the driving rod will move back under the action of the first spring and slide into the next first positioning groove along the second inclined slide groove, so that the feeding slider can move from the previous feeding groove to the next feeding groove.

[0015] Optionally, the second guide groove includes a third inclined slide groove communicating with the previous second positioning groove and a fourth inclined slide groove communicating with the next second positioning groove. The third inclined slide groove is inclined to the right from the direction from the loading slider to the sliding seat, and the fourth inclined slide groove is inclined to the left from the direction from the loading slider to the sliding seat. The third and fourth inclined slide grooves form a second limiting groove, which is located on one side of the fourth inclined slide groove. The central axis of the second positioning groove passes through the inclined surface of the third inclined slide groove.

[0016] By adopting the above technical solution, when the drive rod is located in the first positioning groove at the tail end, during the process of the sliding seat moving back, the drive rod will first enter the second positioning groove at the front end through the first connecting groove, and then be inserted into the second limiting groove along the third inclined sliding groove. Since the second limiting groove is located on one side of the fourth inclined sliding groove, after the hook is disengaged from the drive rod, the drive rod will move back under the action of the first spring and slide into the next second positioning groove along the fourth inclined sliding groove. Thus, the feeding slider can move in the opposite direction from the previous feeding groove to the next feeding groove.

[0017] Optionally, the first connecting groove is a vertical through groove, and the second connecting groove includes a fifth inclined slide groove that communicates with the second positioning groove at the tail end and a sixth inclined slide groove that communicates with the first positioning groove at the front end. The fifth inclined slide groove is inclined to the left from the direction from the loading slider to the sliding seat, and the sixth inclined slide groove is inclined to the right from the direction from the loading slider to the sliding seat.

[0018] By adopting the above technical solution, when the drive rod is located in the second positioning groove at the tail end, during the process of the sliding seat moving back, it can first bypass the first inclined groove through the fifth inclined groove, and then smoothly slide into the first positioning groove at the front end along the sixth inclined groove.

[0019] Optionally, the hook includes a hook body and an elastic telescopic rod fixedly mounted on the hook body. The elastic telescopic rod includes a tube body and a rod body slidably mounted inside the tube body. The tube body is fixedly mounted on the hook body. A second spring is provided inside the tube body. One end of the second spring is connected to the inner end of the rod body, and the other end is fixedly connected to the inner wall of the tube body. The elastic force of the second spring is greater than that of the first spring.

[0020] By adopting the above technical solution, when the hook pulls the drive rod to the first limiting groove, the drive rod will stop moving. However, the drive rod needs to be engaged in the second limiting groove, which requires the drive rod to move backward a certain distance. This limits the drive mechanism to only using cylinders or hydraulic cylinders, and reciprocating screw drive mechanisms cannot be used. However, in this application, an elastic telescopic rod is provided on the hook body, so reciprocating screw drive mechanisms can also be used, and the reciprocating screw drive mechanism operates more stably.

[0021] Optionally, the drive rod includes a slide bar and a rotating wheel rotatably disposed at the end of the slide bar, the rotating wheel being located within a first positioning groove.

[0022] By adopting the above technical solution, a rotating wheel is rotatably installed on the slide rod, making the movement of the drive rod smoother.

[0023] Optionally, a locking block is provided at one end of the slide bar relative to the rotating wheel, and positioning blocks are respectively provided in the first positioning groove and the second positioning groove excluding the front and rear ends. The positioning block is provided with a locking groove that engages with the locking block.

[0024] By adopting the above technical solution, after the card block is inserted into the card slot, the feeding slider can be positioned so that the feeding groove on the feeding slider is aligned with the inlet of the polishing machine, thereby making it less likely for the push rod to jam during the feeding process.

[0025] A polishing machine includes a polishing assembly and the fastener polishing machine feeding mechanism described above.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] The polishing machine described in this application allows operators to continuously feed materials without stopping the machine, making operation more convenient and smoother. The linkage mechanism enables the feeding slider to move intermittently, eliminating the need for an additional power source, resulting in a simpler structure and lower manufacturing costs.

The sliding seat 2 is provided with a push rod 3, and the base 1 is provided with a driving mechanism 4 for driving the sliding seat 2 to move back and forth. The driving mechanism 4 in this application includes a housing, a motor, a reciprocating screw, and a sliding block. The reciprocating screw is rotatably mounted inside the housing, and the motor is mounted on the housing and connected to the reciprocating screw. The motor drives the reciprocating screw to rotate. The sliding block is slidably mounted inside the housing, and the reciprocating screw passes through the sliding block. When the reciprocating screw rotates, it can drive the sliding block to move back and forth. The sliding block passes through the housing and is connected to the sliding seat 2, thereby driving the sliding seat 2 to move back and forth. The driving mechanism 4 can also be a cylinder or a hydraulic cylinder.

[0036] Reference Figure 1 and Figure 2A support platform 5 is provided on the base 1. A loading slider 6 is provided on the support platform 5, which slides laterally relative to the push rod 3. The loading slider 6 is provided with three loading slots 7 for horizontally stacking fasteners. The loading slot 7 is an arc-shaped body that is a long tube divided into two along its central axis. The two ends of the loading slot 7 are connected to the outside. The loading slots 7 are arranged along the sliding direction of the loading slider 6. The central axis of the loading slot 7 is parallel to the central axis of the push rod 3. Baffles 36 are provided on the base 1 on the front and rear sides of the loading slot 7. The baffles 36 are provided with openings 38 for the push rod 3 to pass through. The baffles 36 can limit the fasteners that are not in the loading area of ​​the loading slot 7, so that they are not easy to fall off during the movement of the loading slider 6.

[0037] Reference Figure 1-4 As shown, a linkage mechanism 8 is provided between the sliding seat 2 and the feeding slider 6, which causes the feeding slider 6 to move intermittently for feeding as the sliding seat 2 moves back. The linkage mechanism 8 includes a drive rod 81 and a first spring 82. The bottom of the feeding slider 6 is provided with three first positioning grooves 9 corresponding one-to-one with the feeding slots 7. A sliding groove 10 is provided on the base 1. One end of the drive rod 81 is slidably connected in the sliding groove 10, and the other end is located in any of the first positioning grooves 9. A channel 37 is provided on the support platform 5 for the drive rod 81 to slide back and forth. The sliding direction of the drive rod 81 is the same as that of the sliding seat 2. The first spring 82 is located in the sliding groove 10, and one end of the first spring 82 is located in the sliding groove 10. The drive rod 81 is connected to the drive rod 81 at one end and to the inner wall of the sliding groove 10 at the other end. The drive rod 81 is pressed against the inner wall of the sliding groove 10 away from the sliding seat 2 by the first spring 82. The sliding seat 2 is provided with a connecting rod 11, which passes through the channel 37. The connecting rod 11 is provided with a hook 12 that moves the drive rod 81 as the sliding seat 2 moves back. The bottom of the loading slider 6 is provided with a first guide groove 13 that guides the drive rod 81 into the next first positioning groove 9 as it slides. The bottom of the loading slider 6 is provided with a reset groove 14 that guides the drive rod 81 from the tail end first guide groove 13 into the front end first guide groove 13 as it slides. Figure 4 The rightmost first positioning groove 9 is the front first positioning groove 9, and the leftmost first positioning groove 9 is the tail first positioning groove 9. The reset groove 14 is connected to the front and rear first guide grooves 13 respectively.

[0038] Reference Figure 4As shown, the first guide groove 13 includes a first inclined slide 19 connected to the previous first positioning groove 9 and a second inclined slide 20 connected to the next first positioning groove 9. The first inclined slide 19 is inclined to the left from the direction of the loading slider 6 to the sliding seat 2, and the second inclined slide 20 is inclined to the right from the direction of the loading slider 6 to the sliding seat 2. The first inclined slide 19 and the second inclined slide 20 form a first limiting groove 25. The first limiting groove 25 is located on one side of the second inclined slide 20, and the central axis of the first positioning groove 9 passes through the inclined surface of the first inclined slide 19. When the hook 12 pulls the drive rod 81 to move along the sliding groove 10, the drive rod 81 will move from the first positioning groove 9 to the first inclined sliding groove 19, and slide along the inclined surface of the first inclined sliding groove 19 into the first limiting groove 25. The drive rod 81 stops moving, and then the hook 12 moves back. After losing the force of the hook 12, the drive rod 81 will move in the opposite direction along the sliding groove 10 under the force of the first spring 82. At the same time, the drive rod 81 will slide along the inclined surface of the second inclined sliding groove 20 into the next first positioning groove 9. At this time, the loading slider 6 completes one lateral movement, moving from a certain loading groove 7 to the next loading groove 7.

[0039] The reset groove 14 includes three second positioning grooves 15 that correspond one-to-one with the first positioning groove 9. A second guide groove 16 is provided between two adjacent second positioning grooves 15 to guide the drive rod 81 as it slides into the next second positioning groove 15. The first guide groove 13 and the second guide groove 16 have opposite guiding directions. The bottom of the loading slider 6 is provided with a first connecting groove 17 guiding the drive rod 81 from the tail end of the first positioning groove 9 into the front end of the second positioning groove 15. The bottom of the loading slider 6 is also provided with a second connecting groove 18 guiding the drive rod 81 from the tail end of the second positioning groove 15 into the front end of the first positioning groove 9. Figure 4 The leftmost second positioning groove 15 is the front second positioning groove 15, and the rightmost second positioning groove 15 is the tail second positioning groove 15.

[0040] The second guide groove 16 includes a third inclined slide groove 21 communicating with the previous second positioning groove 15 and a fourth inclined slide groove 22 communicating with the next second positioning groove 15. The third inclined slide groove 21 is inclined to the right from the direction from the loading slider 6 to the sliding seat 2, and the fourth inclined slide groove 22 is inclined to the left from the direction from the loading slider 6 to the sliding seat 2. The third inclined slide groove 21 and the fourth inclined slide groove 22 form a second limiting groove 26, which is located on one side of the fourth inclined slide groove 22. The central axis of the second positioning groove 15 passes through the inclined surface of the third inclined slide groove 21. The first connecting groove 17 is a vertical through groove. The second connecting groove 18 includes a fifth inclined slide groove 23 communicating with the tail end second positioning groove 15 and a sixth inclined slide groove 24 communicating with the front end first positioning groove 9. The fifth inclined slide groove 23 is inclined to the left from the direction from the loading slider 6 to the sliding seat 2, and the sixth inclined slide groove 24 is inclined to the right from the direction from the loading slider 6 to the sliding seat 2. When the drive rod 81 is located in the first positioning groove 9 at the tail end, as the hook 12 pulls the drive rod 81 to move, the drive rod 81 will first enter the second positioning groove 15 at the front end through the first connecting groove 17. The hook 12 continues to pull the drive rod 81 to move, and the drive rod 81 will enter the second limiting groove 26 along the third inclined sliding groove 21. The drive rod 81 stops moving, and then the hook 12 moves back. After losing the force of the hook 12, the drive rod 81 will move in the opposite direction along the sliding groove 10 under the force of the first spring 82. At the same time, the drive rod 81 will slide into the next second positioning groove 15 along the inclined surface of the fourth inclined sliding groove 22. At this time, the feeding slider 6 completes a reverse lateral movement, moving from a certain feeding groove 7 to the next feeding groove 7. After the drive rod 81 moves from the upper second positioning groove 15 to the tail second positioning groove 15, the drive rod 81 will continue to move under the action of the first spring 82 and directly enter the fifth inclined slide groove 23. It will first bypass the first inclined slide groove 19 through the fifth inclined slide groove 23, and then smoothly slide into the front first positioning groove 9 along the sixth inclined slide groove 24.

[0041] Reference Figure 2 and Figure 3As shown, the hook 12 includes a hook body 27 and an elastic telescopic rod 28 fixedly mounted on the hook body 27. The elastic telescopic rod 28 includes a tube body 29 and a rod body 30 slidably mounted inside the tube body 29. The tube body 29 is fixedly mounted on the hook body 27. A second spring 31 is provided inside the tube body 29. One end of the second spring 31 is connected to the inner end of the rod body 30, and the other end is fixedly connected to the inner wall of the tube body 29. The elastic force of the second spring 31 is greater than the elastic force of the first spring 82. When the hook 12 pulls the drive rod 81, the rod body 30 abuts against the drive rod 81 and pushes the drive rod 81 to move. During this process, the drive rod 81 will push the first spring 82 to compress, and the rod body 30 will also push the second spring 31 to compress to a certain extent. When the drive rod 81 moves into the first positioning groove 9, the drive mechanism 4 will continue to drive the hook body 27 to move. At this time, the rod body 30 will retract into the pipe, and the second spring 31 will be compressed. When the hook 12 pulls the drive rod 81 from the tail end of the first positioning groove 9 to the second limiting groove 26, the second spring 31 will be compressed, and the rod body 30 will push the second spring 31 to compress to a certain extent. However, the elastic telescopic rod 28 still has enough length to push the drive rod 81 into the second limiting groove 26. When the drive rod 81 abuts into the second limiting groove 26, the drive mechanism 4 will drive the hook body 27 to move in the opposite direction.

[0042] Reference Figure 2 and Figure 3 As shown, the drive rod 81 includes a slide rod 32 and a rotating wheel 33 rotatably disposed at the end of the slide rod 32. The rotating wheel 33 is located in the first positioning groove 9. The design of the rotating wheel 33 makes the drive rod 81 move more smoothly.

[0043] Reference Figure 3 and Figure 4 As shown, a locking block 34 is provided at one end of the slide rod 32 relative to the rotating wheel 33. Positioning blocks 40 are respectively provided in the first positioning groove 9 and the second positioning groove 15 (excluding the front and rear ends). Each positioning block 40 has a locking groove 35 that engages with the locking block 34. When the drive rod 81 enters the first positioning groove 9 or the second positioning groove 15 (excluding the front and rear ends), the locking block 34 will engage with the locking groove 35, thus positioning the feeding slider 6.

[0044] The implementation principle of the fastener polishing machine feeding mechanism in this application embodiment is as follows: Before processing, the operator can pre-place fasteners in each feeding slot 7. The drive mechanism 4 can drive the sliding seat 2 to move forward, so that the fastener in one of the feeding slots 7 can be conveyed to the polishing machine for polishing by the push rod 3. When the drive mechanism 4 drives the sliding seat 2 to move back, the linkage mechanism 8 will drive the feeding slider 6 to move, so that the next feeding slot 7 is aligned with the push rod 3. The operator can then place fasteners in the empty feeding slot 7. The drive mechanism 4 and the linkage mechanism 8 can drive the feeding slider 6 to move back and forth, so that the machine does not need to be stopped. The operator only needs to feed the empty feeding slot 7.
