Description

Technical Field

[0001] The present invention relates to the technical field of deburring equipment assembly, in particular to a fine burr processing device for switch stamping parts. Background Art

[0002] Stamping is a forming process that uses a press and a die to apply external force to sheet materials, strips, tubes, and profiles, causing them to plastically deform or separate, thereby obtaining a workpiece (stamped part) of the desired shape and size. Currently, switch housings are mostly produced using stamping. The resulting switch stamped parts are equipped with through-holes and threaded holes. However, burrs may exist on the outer surface, inside the through-holes, and at the openings of the threaded holes, potentially affecting the quality of the switch stamped parts. Therefore, these parts require deburring. Currently, most equipment used to deburr switch stamped parts can only deburr the outer surface, inside the through-holes, and at the openings of the threaded holes. After each process step, the switch stamped parts are manually transferred to the next machine. This production method is inefficient and labor-intensive. Therefore, it is necessary to develop a processing device that can perform precise deburring of the outer surface, inside the through-holes, and at the openings of the threaded holes of switch stamped parts in one go.

[0059] Example:

[0060] This embodiment is used for Figure 3 The switch stamping part 12 is shown with refined burr processing.

[0061] like Figure 1-2 and Figure 4-9 As shown, a fine burr processing equipment for switch stamping parts includes a frame, on which a screening and feeding device 1, a sorting and conveying device 2, a conveyor belt 3, a rough grinding device 4, a transfer device 5, a fine grinding device 6, a transition device 7, a polishing and feeding device 8, a polishing device 9 and a storage box 10 are installed in sequence according to the production process.

[0062] like Figure 4 and Figure 10-11 As shown, the screening and feeding device 1 includes a vibrating plate 101, an electric push rod 102 and a photoelectric switch 103; the vibrating plate 101 is fixedly mounted on the frame, and the electric push rod 102 is mounted on the discharge port of the vibrating plate 101; the telescopic end of the electric push rod 102 and the top of the discharge port of the vibrating plate 101 are both equipped with a photoelectric switch 103, and the photoelectric switch 103 is used to detect the orientation of the through hole 1201 and the threaded opening 1201 of the switch stamping 12, and the electric push rod 102 is used to push the switch stamping 12 with the through hole 1201 and the threaded opening 1201 facing incorrectly back into the vibrating plate 101; the correct orientation of the switch stamping 12 is that the through hole 1201 faces upward and the threaded hole 1202 faces backward.

[0063] like Figure 1-2 、 Figure 4 and Fig.12As shown, the sorting and conveying device 2 includes a conveyor belt 201, a limiting movable plate 202, a servo slide 203, a servo cylinder 204, a shift rod 205 and a support plate 206; the conveyor belt 201 is installed on the frame, and its starting end is connected to the discharge port of the vibration plate 101, and a blocking block is fixedly installed on the outflow end; the support plate 206 is fixedly installed on the rear side of the conveyor belt 201 and connected to the conveyor belt 2 3; the servo slide 203 is located at the front side of the conveyor belt 201 and is installed on the frame, and the limiting movable plate 202 is installed on the servo slide 203; the sliding direction of the limiting movable plate 202 is perpendicular to the conveyor belt 201; the servo cylinder 204 is installed on the rear side of the conveyor belt 201, and the shift rod 205 is fixedly installed on the telescopic end of the servo cylinder 204;

[0064] Among them, a door-shaped transfer frame is provided on the rear end of the limit moving plate 202. When the transfer frame is connected to the conveyor belt 201, the switch stamping part 12 on the conveyor belt 201 enters the transfer frame, and the switch stamping part 12 is finally blocked by the blocking block; the transfer frame accommodates a number of switch stamping parts 12; the servo slide 203 drives the limit moving plate 202 to move back and forth at a certain frequency; when the servo slide 203 drives the limit moving plate 202 to move backward, the switch stamping part 12 in the transfer frame is pushed onto the support plate 206. During this process, the switch stamping part 12 on the conveyor belt 201 is blocked in the limit moving plate. Outside the side of the plate 202; after the transfer frame returns to its original position, the blocked switch stamping part 12 enters the transfer frame and is then pushed onto the support plate 206; the lower part of the lever 205 is C-shaped, and its bottom cross bar is lower than the transfer frame. When the switch stamping part 12 is pushed onto the support plate 206, the servo cylinder 204 drives the lever 205 to move, and the bottom cross bar of the lever 205 passes through the transfer frame and shifts the switch stamping part 12 onto the conveyor belt 2 3; in this way, the sorting and conveying device 2 arranges the switch stamping parts 12 with the correct orientation but loose arrangement screened out by the screening and feeding device 1 into a tight queue in batches and conveys them to the conveyor belt 2 3.

[0066] like Figure 5-7 and Figure 13-15As shown, the rough grinding device 4 includes a rough grinding head 401, a rough grinding motor 402, a servo cylinder 2 403, a lifting frame 1 404, a servo cylinder 3 405, a push plate 406 and a support plate 2 407; the lifting frame 1 404 is located above the tail of the conveyor belt 2 3 and is vertically slidably mounted on the frame and is fixedly connected to the telescopic end of the servo cylinder 2 403 vertically mounted on the frame; the support plate 2 407 is fixedly mounted on the front side of the tail of the conveyor belt 2 3; 10 rough grinding motors 406 are installed in a straight line on the lifting frame 1 404. 2. A coarse grinding head 401 is fixedly mounted on the output end of the coarse grinding motor 402, and is located above the second support plate 407. Below each coarse grinding head 401 is a push plate 406 that slides horizontally on the frame, with the sliding direction of the push plate 406 being perpendicular to the second conveyor belt 3. The rear end of the push plate 406 is fixedly connected to the telescopic end of the third servo cylinder 405 mounted on the frame. A door-shaped limit frame is provided at the front end of the push plate 406, and a coarse grinding through hole is provided at the top end of the limit frame corresponding to the coarse grinding head 401.

[0067] After the conveyor belt 2 3 conveys the switch stamping part 12 to the corresponding push plate 406, the switch stamping part 12 is located in the limit frame, and the servo cylinder 3 405 drives the push plate 406 to move forward, and the push plate 406 pushes the switch stamping part 12 onto the support plate 2 407. At this time, the switch stamping part 12 is located directly below the rough grinding head 401; the servo cylinder 2 403 drives the lifting frame 1 404 to move downward, and the rough grinding head 401 passes through the rough grinding through hole and enters the through hole 1201 of the switch stamping part 12; the rough grinding motor 402 drives the rough grinding head 401 to rotate, thereby rough grinding the through hole 1201.

[0068] like Figure 6 、 Fig.16 and Fig.19 As shown, the transfer device 5 is located in front of the rough grinding device 4 and the fine grinding device 6, and includes a servo cylinder 4 501, a servo slide 2 502 and a transfer plate 503; the servo slide 2 502 is horizontally slidably mounted on the frame; the servo cylinder 4 501 is horizontally mounted on the frame, and its telescopic end is fixedly connected to the servo slide 2 502; the transfer plate 503 is mounted on the servo slide 2 502; the transfer plate 503 is provided with 10 notches for pushing the switch stamping part 12; the sliding direction of the servo slide 2 502 is parallel to the conveyor belt 2 3, and the sliding direction of the transfer plate 503 is perpendicular to the conveyor belt 2 3; the transfer plate 503 moves between the support plate 2 407 and the support frame 601;

[0069] After the rough grinding of the through-hole 1201 of the switch stamping part 12 is completed, the servo cylinder four 501 drives the servo slide table two 502 to move, so that the transfer plate 503 moves in front of the support plate two 407. The servo slide table two 502 drives the transfer plate 503 to move backward, and the switch stamping part 12 is embedded into the corresponding notch on the transfer plate 503. The servo cylinder four 501 drives the servo slide table two 502 to move, so that the transfer plate 503 pushes the switch stamping part 12 onto the support frame 601. The height of the transfer plate 503 is lower than the front bottom side of the pushing plate 406. During this movement of the transfer plate 503, the side of the transfer plate 503 can push the switch stamping part 12 that has been finely ground and the thread hole ground on the support frame 601 onto the conveyor belt three 701; after pushing the switch stamping part 12 to be finely ground and the thread hole ground onto the support frame 601, the servo slide table two 502 drives the transfer plate 503 to move forward, and the switch stamping part 12 disengages from the notch.

[0070] As Figure 1-2 、 Figure 6-7 and Figure 17-20 shown, the fine grinding device 6 includes a support frame 601, a lifting frame two 602, a servo cylinder five 603, a fine grinding head 604, a fine grinding motor 605, a moving plate 606, a thread hole grinding head 607, a thread hole grinding motor 608 and a servo slide table three 609; the support frame 601 is fixedly installed on the machine frame, and both ends of the support frame 601 are respectively docked with the support plate two 407 and the conveyor belt three 701; the servo cylinder five 603 is installed on the machine frame, and its telescopic end is fixedly installed with the lifting frame two 602; 10 fine grinding motors 605 are installed on the lifting frame two 602 in a straight line, the output end of the fine grinding motor 605 is fixedly installed with the fine grinding head 604, and the fine grinding head 604 is located above the support frame 601; the servo slide table three 609 is fixedly installed on the support frame 601, and the moving plate 606 is installed on the servo slide table three 609; 10 thread hole grinding motors 608 are installed on the moving plate 606 in a straight line, and the output end of the thread hole grinding motor 608 is fixedly installed with the thread hole grinding head 607;

[0071] After the transfer plate 503 pushes the roughly ground switch stamping part 12 onto the support frame 601, the servo cylinder five 603 drives the lifting frame two 602 to descend, the fine grinding head 604 extends into the through-hole 1201 of the switch stamping part 12, the fine grinding motor 605 drives the fine grinding head 604 to rotate, and the through-hole 1201 is finely ground. At the same time, the servo slide table three 609 drives the moving plate 606 to move forward, the thread hole grinding head 607 extends into the thread hole 1202 of the switch stamping part 12, and the thread hole grinding motor 608 drives the thread hole grinding head 607 to rotate, so as to grind the orifice of the thread hole 1202.

[0072] As Figure 1-2 、 Figure 8 and Figure 21 As shown in the figure, the transition device 7 includes a third conveyor belt 701, a sixth servo cylinder 702, a second limit moving plate 703, a seventh servo cylinder 704, and a transition frame 705; the third conveyor belt 701 is installed on the frame and is docked with the support frame 601; the transition frame 705 is fixedly installed on the frame, and a transition slideway is provided thereon, and the transition slideway is docked with the conveyor belt 801 of the polishing and feeding device 8; the sixth servo cylinder 702 is horizontally installed on the transition frame 705, and its telescopic end is fixedly connected to the second limit moving plate 703; the second limit moving plate 703 is slidably installed on the transition frame 705 and intermittently contacts the outflow end of the third conveyor belt 701, and the sliding direction of the second limit moving plate 703 is perpendicular to that of the third conveyor belt 701; a transfer chute parallel to the third conveyor belt 701 is provided on the second limit moving plate 703, and the transfer chute is intermittently docked with the third conveyor belt 701 or the transition slideway; the seventh servo cylinder 704 is installed on the transition frame 705, and the telescopic end thereof is parallel to the third conveyor belt 701, and when the transfer chute is docked with the transition slideway, the telescopic end of the seventh servo cylinder 704 is docked with the transfer chute;

[0073] The sixth servo cylinder 702 drives the second limit moving plate 703 to move, the transfer chute is docked with the third conveyor belt 701, and the switch stamping part 12 on the third conveyor belt 701 enters the transfer chute; then the second limit moving plate 703 moves to make the transfer chute dock with the transition slideway, and the telescopic end of the seventh servo cylinder 704 pushes the switch stamping part 12 in the transfer chute and pushes the switch stamping part 12 into the transition slideway. During the movement of the second limit moving plate 703, the switch stamping part 12 still moving on the third conveyor belt 701 is blocked by the side of the second limit moving plate 703. When the second limit moving plate 703 moves again to make the transfer chute dock with the third conveyor belt 701, the originally blocked switch stamping part 12 on the third conveyor belt 701 quickly enters the transfer chute; the seventh servo cylinder 704 continuously pushes the switch stamping part 12 in the transfer chute to make the switch stamping part 12 enter the fourth conveyor belt 801 of the polishing and feeding device 8 in an orderly manner; thus, the transition device 7 arranges the switch stamping parts 12 that have completed fine grinding and threaded mouth grinding and are transferred in batches by the transfer device 6 into a tight queue and conveys them to the fourth conveyor belt 801 of the polishing and feeding device 8.

[0074] As Figure 8-9 and Figure 22-23 As shown in the figure, the polishing and feeding device 8 includes a fourth conveyor belt 801, a counting sensor 802, an eighth servo cylinder 803, and a feeding push plate 804; the fourth conveyor belt 801 is installed on the frame and is docked with the third conveyor belt 701 of the transition device 7; the feeding push plate 804 is slidably installed on the frame and is fixedly connected to the telescopic end of the eighth servo cylinder 803 installed on the frame; 15 pushing rods are arranged in a straight line on the feeding push plate 804, and the pushing rods are perpendicular to the fourth conveyor belt 801; the counting sensor 802 is installed at the starting end of the fourth conveyor belt 801;

[0075] When the closely arranged switch stamping parts 12 enter the fourth conveyor belt 801 one by one, they will be driven by the fourth conveyor belt 801 to move, and intervals will be generated between the switch stamping parts 12; the fourth conveyor belt 801 starts intermittently. After the fourth conveyor belt 801 conveys 15 switch stamping parts 12 to the positions where 15 pusher rods are located correspondingly, the fourth conveyor belt 801 pauses. The servo cylinder eight 803 drives the feeding push plate 804 to move towards the polishing device 9, and the pusher rods push the switch stamping parts 12 onto the fifth conveyor belt 903 of the polishing device 9; then the servo cylinder eight 803 drives the feeding push plate 804 to return to its original position, and the fourth conveyor belt 801 continues to operate; the counting sensor 802 controls the operation of the fourth conveyor belt 801 by detecting the number of switch stamping parts 12 entering the fourth conveyor belt 801; thus, the polishing feeding device 8 generates intervals between the closely arranged switch stamping parts 12 conveyed by the transition device 7 and conveys them to the polishing device 9 in batches.

[0076] As Figure 9 and Figures 24-27 shown, the polishing device 9 includes an XYZ-axis manipulator 901, a polisher 902, a fifth conveyor belt 903, an electric push rod two 904, a limit switch 905, and a diversion frame 906; the fifth conveyor belt 903 is installed on the frame, is perpendicular to the fourth conveyor belt 801, and is docked with the pusher rods of the feeding push plate 804; the diversion frame 906 is arranged above the fifth conveyor belt 903 and is driven to lift by three pairs of electric push rods two 904 installed on the side of the fifth conveyor belt 903; there are 15 diversion limit slots parallel to the fifth conveyor belt 903 and corresponding to the pusher rods on the diversion frame 906; each diversion limit slot allows a row of switch stamping parts 12 to pass through; baffles 9061 perpendicular to the diversion limit slots are installed at the feeding end and the middle of the diversion frame 906; 15 limit switches 905 corresponding to the diversion limit slots are installed along a straight line on the baffle 9061; the XYZ-axis manipulator 901 is installed on the frame, and 15 polishers 902 corresponding to the diversion limit slots are installed along a straight line on the moving end of the XYZ-axis manipulator 901;

[0077] The polisher 902 includes a polishing motor 9021, a polishing head 9022, and a mounting bracket 9023; the mounting bracket 9023 is fixedly installed on the moving end of the XYZ-axis manipulator 901; polishing motors 9021 are installed on both sides and the top of the mounting bracket 9023, and the output end of the polishing motor 9021 is fixedly installed with a polishing head 9022;

[0078] The pusher rod pushes the switch stamping part 12 onto the fifth conveyor belt 903. The fifth conveyor belt 903 drives the switch stamping part 12 to move. The switch stamping part 12 first contacts the limit switch 905 at the feeding end of the diversion frame 906. The second electric push rod 904 drives the diversion frame 906 to move upward. The switch stamping part 12 passes through the baffle 9061 at the feeding end and enters the corresponding diversion limit slot. After the switch stamping part 12 passes through the baffle 9061 at the feeding end, the second electric push rod 904 drives the diversion frame 906 to descend to its original position; The XYZ-axis manipulator 901 drives the polisher 902 to move. The mounting frame 9023 covers the switch stamping part 12 in the corresponding diversion limit slot. The polishing motor 9021 drives the polishing head 9022 to rotate to polish the switch stamping part 12. When the switch stamping part 12 is driven by the fifth conveyor belt 903 to move in the corresponding diversion limit slot, the polisher 902 is driven by the XYZ manipulator 901 to move accordingly;

[0079] Before the switch stamping part 12 contacts the limit switch 905 in the middle of the diversion frame 906, the polisher 902 rises and no longer covers the switch stamping part 12; When the switch stamping part 12 contacts the limit switch 905 in the middle of the diversion frame 906, the second electric push rod 904 drives the diversion frame 906 to move upward. The moving distance this time is less than the previous upward moving distance. The through hole 1201 of the switch stamping part 12 is still blocked by the baffle 9061. When the switch stamping part 12 passes through the baffle 9061 in the middle of the diversion frame 906, this baffle 9061 will deflect the switch stamping part 12, causing the switch stamping part 12 to flip 90°. After flipping, the switch stamping part 12 passes through the baffle 9061 in the middle of the diversion frame 906. The polisher 902 moves and continues to cover the corresponding switch stamping part 12 to polish the flipped switch stamping part 12; After polishing, the polisher 902 moves and leaves the switch stamping part 12. The switch stamping part 12 falls into the storage box 10 driven by the fifth conveyor belt 903;

[0080] As Figure 1-2 shown, the storage box 10 is arranged at the discharge port of the polishing device 8 and fixedly installed on the frame for storing the switch stamping parts 12 that have completed deburring.

[0081] As Fig.28As shown, this embodiment also includes a control terminal 11, which includes a main controller, a human-computer interaction display screen, an information transmission module, a storage module and a power supply module, and the main controller and the human-computer interaction display screen, the information transmission module, the storage module, the power supply module and the vibration plate 101, the electric push rod 102, the photoelectric switch 103, the conveyor belt 1 201, the servo slide 1 203, the servo cylinder 1 204, the conveyor belt 2 3, the rough grinding motor 402, the servo cylinder 2 403, the servo cylinder 3 405, the servo cylinder 4 501, the servo slide 2 502, the servo cylinder 5 603, the fine grinding motor 605, the threaded grinding motor 608, the servo slide 3 609, the conveyor belt 3 701, the servo cylinder 6 702, the servo cylinder 704, the conveyor belt 4 801, the counting sensor 802, the servo cylinder 803, the XYZ axis manipulator 901, the polishing motor 9021, the transmission The conveyor belt five 903, the electric push rod two 904, and the limit switch 905 are all electrically connected; the main controller is used to control the operation of the fine burr processing equipment for the entire switch stamping parts; the human-computer interaction display screen is used to set the running distance values of the screening and feeding device 1, the sorting and conveying device 2, the conveyor belt two 3, the rough grinding device 4, the transfer device 5, the fine grinding device 6, the transition device 7, the polishing and feeding device 8 and the polishing device 9, as well as the automatic operation control after determining the set value; the information transmission module is used for information transmission between the main controller and the screening and feeding device 1, the sorting and conveying device 2, the conveyor belt two 3, the rough grinding device 4, the transfer device 5, the fine grinding device 6, the transition device 7, the polishing and feeding device 8 and the polishing device 9; the power supply module is used to provide a stable power supply for the control terminal 11; the storage module is used to store the operation information data of the fine burr processing equipment for the entire switch stamping parts.

[0082] The working steps of this embodiment are as follows:

[0083] In the first step, the screening and feeding device 1 screens out the switch stamping parts 12 facing the correct direction and conveys them to the sorting and conveying device 2;

[0084] In the second step, the sorting conveyor device 2 arranges the switch stamping parts 12 with the correct orientation but loose arrangement screened by the screening and feeding device 1 into a tight queue in batches and conveys them to the conveyor belt 2 3;

[0085] In the third step, the conveyor belt 2 3 creates spaces between the switch stamping parts 12. Each time the conveyor belt 2 3 is started, the 10 switch stamping parts 12 arranged at intervals are conveyed to the corresponding push plates 406 in the rough grinding device 4;

[0086] Step 4: The rough grinding device 4 performs rough grinding on 10 switch stamped parts 12 arranged at intervals; subsequently, the transfer device 5 transfers the 10 rough-ground switch stamped parts 12 to the fine grinding device 6, and at the same time transfers the 10 switch stamped parts 12 that have completed fine grinding and threaded port grinding on the fine grinding device 6 to the transition device 7;

[0087] Step 5: The transition device 7 arranges the switch stamped parts 12 that have completed fine grinding and threaded port grinding and are transferred in batches by the transfer device 6 into a tight queue and conveys them to the conveyor belt four 801 of the polishing loading device 8;

[0088] Step 6: The polishing loading device 8 creates intervals between the tightly arranged switch stamped parts 12 conveyed by the transition device 7 and conveys them to the polishing device 9 in batches;

[0089] Step 7: The polishing device 9 polishes the switch stamped parts 12 and conveys them into the storage box 10 after polishing;

[0090] The above steps complete the deburring process of the switch stamped parts 12.
