Description

Technical Field

[0001] The present application relates to the technical field of polishing devices, and particularly relates to a polishing device for the production and processing of automotive parts. Background Art

[0002] Automotive parts are the basic units that constitute the overall functions and performance of an automobile. There are various types of them, and the connection of automotive parts is crucial. Among them, the connection of some parts requires the use of bolts for fixation. Bolts also belong to a type of automotive parts. During the production process of bolts, there will be a small amount of burrs at both ends. In order to improve the precision of bolt connection and fixation, the bolts need to be polished before use (mainly the two ends of the bolts are polished, because when using the bolts, any one end will contact the connection surface of the connecting parts. If there are burrs at the ends of the bolts, it will affect the tightening precision of the bolts, and in serious cases, it will scratch the connecting parts).

[0003] The existing parts (bolts) polishing devices mainly complete the polishing of parts through the combination of a polishing head, a parts placement mechanism, and multiple driving mechanisms. However, there are still certain problems in the current polishing devices during use. During the polishing process, the burrs (debris) on the tabletop and the polishing head cannot be cleaned in time. Polishing in a state with debris will affect the subsequent polishing effect, and the existing polishing devices cannot complete double-sided polishing coherently, resulting in relatively high energy consumption.

[0004] Therefore, the present application proposes a polishing device for the production and processing of automotive parts to solve the above problems. Summary of the Invention

[0015] Preferably, an arc-shaped groove is opened on the upper end of the storage tray. The debris collection box is placed in the arc-shaped groove. An electromagnet sheet is provided on the inner wall of the debris collection box. When the debris collection box is located directly below the arc-shaped mounting plate, the arc formed by the electromagnet disk and the two polishing heads is smaller than the arc of the electromagnet sheet.

[0016] Preferably, the positioning and flipping mechanism includes a support groove opened in the middle of the upper end of the storage tray. A connection disk is arranged in the support groove. A plurality of connecting rods are fixedly connected to the outer surface of the connection disk. Positioning magnets are fixedly connected to the outer ends of the plurality of connecting rods. The plurality of positioning magnets attract and position the plurality of bolts;

[0017] A plurality of rectangular grooves communicating with the support groove are opened on the upper end of the storage tray. The corresponding connecting rods and positioning magnets are located in the corresponding rectangular grooves.

[0018] Preferably, when polishing, both the connection disk and the upper end of the bolt protrude from the upper end surface of the storage tray.

[0020] A number of part placement grooves on both sides are symmetrically distributed on both sides of the transmission shaft, so that the flipped bolts can smoothly fall into the number of part placement grooves;

[0021] The upper end of the base is rotatably connected with an annular turntable located outside the support column. A telescopic cylinder is installed on the upper end of the annular turntable. The telescopic end of the telescopic cylinder is fixedly connected to the mounting shell.

[0026] Compared with the prior art, the present application has the following beneficial technical effects:

[0027] In the present application, by arranging a polishing mechanism and an electromagnet disk at the lower end of the arc-shaped mounting plate, when the storage tray rotates, it will drive the polishing head to rotate and polish the upper ends of a number of bolts in turn. The polished bolts are successively conveyed below the electromagnet disk. Under the magnetic attraction of the electromagnet disk, the burrs on the upper ends of the polished bolts will be sucked away. When the storage tray rotates one circle, the polishing of the upper ends of a number of bolts is completed. At this time, the electromagnet disk loses magnetic attraction. Under the magnetic attraction of the electromagnet sheet, the burrs on the two polishing heads and the electromagnet disk will be sucked into the debris collection box to maintain the polishing effect for the next time;

[0028] By arranging a positioning and flipping mechanism at the upper end of the storage tray, when the storage tray rotates one full circle, the bump touches the first touch switch, which will activate the telescopic cylinder to extend through the controller. Then, the output shaft of the first motor is controlled to slowly rotate 180 degrees, and then the telescopic end of the telescopic cylinder retracts, enabling several bolts to be flipped and smoothly fall into several parts placement slots, facilitating the polishing of the other end faces of the several bolts.

[0029] To sum up, the structure of this application is reasonably designed. After polishing each bolt, the burrs or fine debris from the polishing can be cleaned off. Moreover, after the polishing of all bolt end faces is completed, the debris on the electromagnet disk and the debris on the two polishing heads can be cleaned, ensuring the polishing effect of the next circle; with the cooperation of the positioning and flipping mechanism, several bolts can be flipped, and then the double-sided polishing of several bolts can be completed coherently, improving the polishing efficiency. The entire device is energy-saving and environmentally friendly. Description of the Drawings

[0047] Embodiment

[0048] Such as Figures 1-7As shown in the figure, a polishing device for the production and processing of automotive parts proposed in this application includes a base 1 and a support column 2 rotatably connected to the upper end thereof. A pair of support bottom plates 18 are fixedly connected to the bottom end of the base 1. A second motor is installed at the bottom end of the base 1, and the output shaft of the second motor is fixedly connected to the support column 2. A support plate is fixedly connected between the two support bottom plates 18, and the second motor is installed on the upper end of the support plate. The upper end of the support column 2 is fixedly connected to a placement tray 3. When the second motor works, it can drive the placement tray 3 to rotate for polishing treatment.

[0049] It further includes a plurality of part placement grooves 8 opened on the upper end of the placement tray 3. Bolts 10 are placed in the plurality of part placement grooves 8. A positioning and flipping mechanism 9 for flipping and controlling the plurality of bolts 10 is arranged on the upper end of the placement tray 3. The side wall of the base 1 is connected to an arc-shaped vertical plate 4 through an arc-shaped support plate 23. A polishing mechanism 6 and an electromagnet disk 7 are installed on the upper end of the arc-shaped vertical plate 4 through an arc-shaped mounting plate 5. A debris collection box 12 that cooperates with the polishing mechanism 6 and the electromagnet disk 7 is arranged on the upper end of the placement tray 3. The debris collection box 12 is arc-shaped. An arc-shaped groove 11 is opened on the upper end of the placement tray 3, and the debris collection box 12 is placed in the arc-shaped groove 11. An electromagnet sheet 13 is arranged on the inner wall of the debris collection box 12.

[0050] An internal gear ring 15 is installed on the upper end of the placement tray 3 through a support ring 14, and the internal gear ring 15 is driven in cooperation with the polishing mechanism 6.

[0051] Specifically, the polishing mechanism 6 includes a rectangular connecting rod 61 that slidably penetrates through the arc-shaped mounting plate 5. The upper end of the rectangular connecting rod 61 is fixedly connected with a limiting block 62, and the bottom end of the rectangular connecting rod 61 is fixedly connected with a chassis 63. A spring 69 is sleeved on the outer side of the rectangular connecting rod 61 and is located between the chassis 63 and the arc-shaped mounting plate 5. The upper end of the spring 69 is fixedly connected with the arc-shaped mounting plate 5, and the lower end of the spring 69 is fixedly connected with the chassis 63, enabling the rectangular connecting rod 61 to move upward by a certain distance under the action of an external force. The bottom end of the chassis 63 is rotatably connected with a rotating shaft 64, and a transmission sleeve 65 is fixedly connected to the side wall of the rotating shaft 64. The bottom end of the transmission sleeve 65 is connected with a polishing head 66. The polishing head 66 polishes the bolt 10 (the bottom cross-sectional diameter of the polishing head 66 is larger than the maximum outer diameter of the bolt 10). It should be noted that the outer circle of the bottom end of the polishing head 66 is an arc-shaped part. When the bolt 10 does not move to the lower end of the polishing head 66, the lower end surface of the polishing head 66 is slightly lower than the upper end surface of the bolt 10. When the bolt 10 moves to the edge of the lower end of the polishing head 66, the bolt 10 will contact the arc-shaped part at the bottom end of the polishing head 66, and under the extrusion of the thrust force, the polishing head 66 moves upward by a certain distance, and the bolt 10 smoothly moves to the bottom end of the polishing head 66. Under the action of the resilience of the spring 69, the polishing head 66 abuts against the upper end of the bolt 10, ensuring the polishing effect during the polishing operation. When the debris collection box 12 is located directly below the arc-shaped mounting plate 5, the arc formed by the electromagnet disk 7 and the two polishing heads 66 is smaller than the arc of the electromagnet piece 13. In the state where the electromagnet piece 13 is energized to generate magnetic suction, the debris or burrs on the two polishing heads 66 and the electromagnet disk 7 can be smoothly sucked into the debris collection box 12.

[0052] Among them, two sets of the polishing mechanisms 6 are provided, and the structures of the two polishing mechanisms 6 are the same; the two polishing heads 66 can polish each bolt 10 twice. The polishing head 66 is detachably connected to the transmission sleeve 65. A plurality of groups of threaded grooves are vertically and perpendicularly opened between the transmission sleeve 65 and the polishing head 66, and long screws 67 are threadedly inserted into each group of threaded grooves. The polishing head 66 is fixed to the bottom end of the transmission sleeve 65 through the long screws 67. Because the polishing head 66 will be worn to a certain extent after polishing for a period of time, the polishing head 66 can be replaced according to requirements. The specific method for replacing the polishing head 66 is to detach the arc-shaped vertical plate 4 from the upper end of the arc-shaped support plate 23. The arc-shaped vertical plate 4 and the arc-shaped support plate 23 are installed by means of bolts. After disassembly, loosen the long screws 67 so that the bottom ends of the long screws 67 are disengaged from the threaded grooves of the polishing head 66, and then install a new polishing head 66. Then, tighten the long screws 67 in the reverse direction so that the bottom ends of the long screws 67 are inserted into the threaded grooves at the upper end of the polishing head 66, thus completing the replacement of the polishing head 66.

[0053] An annular groove is provided in the upper side wall of the upper ends of the two transmission sleeves 65. A gear 68 is fixedly connected in each of the two annular grooves. The two gears 68 are not meshed with each other, and the two gears 68 are both meshed and driven with the internal gear ring 15. When the storage tray 3 rotates, it will drive the internal gear ring 15 to rotate synchronously. The internal gear ring 15 is meshed and driven with the two gears 68 to drive the two gears 68 to rotate. The transmission sleeve 65 and the polishing head 66 are driven to rotate by the two gears 68, so as to complete the polishing process when the bolt 10 makes a circular motion.

[0054] Specifically, the positioning and flipping mechanism 9 includes a support groove 910 opened in the middle of the upper end of the storage tray 3. A connection disk 91 is arranged in the support groove 910. A plurality of connecting rods 92 are fixedly connected to the outer surface of the connection disk 91. The outer ends of the plurality of connecting rods 92 are fixedly connected with positioning magnets 99. The plurality of positioning magnets 99 attract and position the plurality of bolts 10. A plurality of rectangular grooves 98 communicating with the support groove 910 are opened in the upper end of the storage tray 3. The corresponding connecting rods 92 and positioning magnets 99 are located in the corresponding rectangular grooves 98. It should be noted that during polishing, both the connection disk 91 and the upper end of the bolt 10 protrude from the upper end surface of the storage tray 3. The connecting rod 92 is connected to the middle of the side wall of the connection disk 91, and the positioning magnet 99 attracts the middle of the side wall of the bolt 10. After flipping the plurality of bolts 10, the upward end surface of the bolt 10 still protrudes from the upper end surface of the storage tray 3, so that both end surfaces of the bolt 10 maintain the same polishing support state.

[0055] Further, the positioning and flipping mechanism 9 further includes a mounting groove 93 opened in the storage tray 3. The mounting groove 93 communicates with the support groove 910. A mounting shell 95 is slidably connected in the mounting groove 93. A first motor 96 is installed in the mounting shell 95. The output end of the first motor 96 is fixedly connected with a transmission shaft 97. One end of the transmission shaft 97 is fixedly connected to the side wall of the connection disk 91; a plurality of parts placement grooves 8 on both sides are symmetrically distributed on both sides of the transmission shaft 97, so that the plurality of bolts 10 after flipping can smoothly fall into the plurality of parts placement grooves 8; the upper end of the base 1 is rotatably connected with an annular turntable 20 located outside the support column 2. A telescopic cylinder 94 is installed on the upper end of the annular turntable 20. The telescopic end of the telescopic cylinder 94 is fixedly connected with the mounting shell 95. A transmission frame 21 is fixedly connected to the side wall of the support column 2. One end of the transmission frame 21 is fixedly connected to the annular turntable 20. The support column 2 drives the annular turntable 20 to rotate synchronously while rotating, so that the telescopic cylinder 94 keeps moving in a circular motion synchronously with the storage tray 3.

[0056] At the upper end of the base 1 described in this application, a controller 19 is installed. At the inner wall of the upper end of the arc-shaped vertical plate 4, a touch switch one 16 and a touch switch two 22 are provided. A convex block 17 is fixedly connected to the outer wall of the support ring 14. When the convex block 17 touches the touch switch one 16, the debris collection box 12 is located directly below the arc-shaped mounting plate 5. The output ends of the touch switch one 16 and the touch switch two 22 are electrically connected to the input end of the controller 19. The output end of the controller 19 is electrically connected to the input end of the second motor. The output end of the controller 19 is also electrically connected to the input ends of the electromagnet disk 7, the telescopic cylinder 94, and the first motor 96.

[0057] The working principle of this embodiment is as follows: First, the bolts 10 to be polished are sequentially placed in a plurality of part placement grooves 8. After the feeding is completed, a plurality of positioning magnets 99 can play a positioning role for the plurality of bolts 10. Next, start the second motor. The output shaft of the second motor rotates to drive the support column 2 to rotate. The support column 2 rotates to drive the placement disk 3 to rotate. When the placement disk 3 rotates, it will sequentially transport the plurality of bolts 10 to the lower end of the polishing mechanism 6, and pass through the first polishing head 66, the second polishing head 66, and the electromagnet disk 7 in sequence. When the electromagnet disk 7 rotates, it will drive the support ring 14 and the internal gear ring 15 to rotate synchronously, so that the internal gear ring 15 meshes with the two gears 68 for transmission, and then drives the polishing head 66 to rotate through the transmission sleeve 65, so that the two polishing heads 66 polish the upward end faces of the bolts 10 passing through in sequence. When the polished bolts 10 pass through the electromagnet disk 7, the electromagnet disk 7 will suck away the debris or burrs on the upward end faces of the polished bolts 10. The magnetic attraction of the electromagnet disk 7 can suck away the debris or burrs without sucking up the bolts 10.

[0058] After the placement tray 3 rotates one full circle, the convex block 17 will touch the first touch switch 16. At this time, the first touch switch 16 sends an electrical signal to the controller 19, which controls the second motor to pause working through the controller 19, and then controls the electromagnet disk 7 to cut off the power and lose the magnetic attraction. The electromagnet sheet 13 will suck the debris or burrs on the two polishing heads 66 and the electromagnet disk 7 into the debris collection box 12. Since the material of the bolt 10 can be attracted by the magnet, the debris or burrs generated during grinding and polishing can also be attracted by the magnet. During this process, the controller 19 will also control the telescopic end of the telescopic cylinder 94 to extend, driving the mounting shell 95 to rise, and then driving the connecting disk 91, the connecting rod 92, and the positioning magnet 99 to rise through the transmission shaft 97, finally causing the bolts 10 with one end polished to rise (the rising height enables several bolts 10 to complete the flipping smoothly). Subsequently, the controller 19 controls the output shaft of the first motor 96 to rotate 180 degrees, enabling several bolts 10 to complete the flipping action. Next, the telescopic end of the telescopic cylinder 94 retracts, causing the several flipped bolts 10 to fall into the several part placement slots 8. After several bolts 10 fall into the several part placement slots 8 again, the controller 19 controls the second motor to start again to continue polishing the other end faces of the several bolts 10. When the placement tray 3 rotates a certain angle, the convex block 17 touches the second touch switch 22, and the second touch switch 22 sends an electrical signal to the controller 19, which controls the electromagnet disk 7 to be powered on to restore the magnetic attraction (to adsorb and clean the debris or burrs generated during the polishing of the flipped bolts 10). This device can clean the burrs or fine debris generated during the polishing of each bolt 10, and can clean the debris on the electromagnet disk 7 and the debris on the two polishing heads 66 after the polishing of all bolt end faces is completed, ensuring the polishing effect of the next circle; with the cooperation of the positioning and flipping mechanism 9, several bolts 10 can be flipped, and then the double-sided polishing of several bolts 10 can be completed coherently, improving the polishing efficiency. After the polishing is completed, the telescopic cylinder 94 is extended, and several bolts 10 are driven to rise away from the part placement slots 8 through the connecting disk 91, the connecting rod 92, and the positioning magnet 99. Next, the polished bolts 10 can be taken off.

[0059] In this device, the arc-shaped groove 11 can be removed regularly for cleaning. After the parts are polished, the debris collection box 12 is deviated from the arc-shaped mounting plate 5, and then the debris collection box 12 is removed (the distance between the upper end face of the placement tray 3 and the internal gear ring 15 is greater than the height of the debris collection box 12, enabling the debris collection box 12 to be taken out smoothly). After the debris collection box 12 is taken out, the electromagnet sheet 13 is powered off to lose the magnetic attraction, and then the collected debris or burrs are poured out. After pouring out, the debris collection box 12 is placed back into the arc-shaped groove 11, and the debris collection box 12 is rotated to the directly below the arc-shaped mounting plate 5 for the next polishing process.
