Description

Technical Field

[0001] This utility model relates to the field of metal stamping parts processing technology, specifically a grinding equipment for metal stamping parts processing. Background Technology

[0002] Hardware refers to parts processed from steel or some non-ferrous metals. Stamped parts refer to parts formed into a specified shape by using a mold and a press to provide the required pressure under room temperature conditions. Hardware stamped parts need to be deburred during the manufacturing process to ensure the smoothness of their surface. Therefore, a grinding device is used to polish their surface.

[0003] In the existing technology, a clamp is used to hold and fix the metal stamping parts for grinding. After grinding, the metal stamping parts are flipped and re-fixed, which reduces the grinding efficiency of the stamping parts. Furthermore, during clamping, the clamping plate will block the surface of the metal stamping parts, thus affecting the thoroughness of grinding. The blocked areas need to be ground again, which further reduces the grinding efficiency of the stamping parts. Therefore, a grinding equipment for processing metal stamping parts is proposed. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a grinding equipment for processing metal stamping parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for processing metal stamping parts, comprising a grinding table and a connecting plate. Two first electric push rods are fixedly connected to the top outer surface of the connecting plate. An electromagnetic chuck is installed at the output end of each first electric push rod. Two vertical plates are fixedly connected to the top outer surface of the connecting plate. A support shaft is rotatably connected to the outer surface of the two vertical plates. A rotating frame is fixedly connected to the outer surface of the support shaft. A second electric push rod is fixedly installed on the outer surface of the vertical plates. A rack is fixedly connected to the output end of the second electric push rod. A gear is fixedly sleeved on the outer surface of the support shaft. The rack engages movably with the outer surface of the gear. Clamping components are provided on both sides of the top outer surface of the rotating frame.

[0006] Furthermore, two support plates are fixedly connected to the top outer surface of the grinding table, and a lead screw is rotatably connected between the two support plates. A second motor is fixedly installed on the outer surface of one of the support plates, and the output end of the second motor is fixedly connected to the lead screw. A threaded block is threadedly connected to the outer surface of the lead screw, and the connecting plate is fixedly connected to the top outer surface of the threaded block.

[0007] Furthermore, a support frame is fixedly connected to the top outer surface of the grinding table, and a first electric slide rail is fixedly installed on the top downward outer surface of the support frame. A second electric slide rail is fixedly connected to the output end of the first electric slide rail, a fifth electric push rod is fixedly installed at the output end of the second electric slide rail, a first motor is fixedly installed at the output end of the fifth electric push rod, and a grinding disc is fixedly connected to the output end of the first motor.

[0008] Furthermore, the clamping assembly includes side plates fixed to both sides of the rotating frame. A third electric push rod is fixedly installed on the outer surface of the side plates. A mounting plate is fixedly connected to the output end of the third electric push rod. A fourth electric push rod is fixedly installed on the side of the mounting plate away from the rotating frame. A clamping plate is fixedly connected to the output end of the fourth electric push rod.

[0009] Furthermore, a sliding rod is fixedly connected between the two support plates, and the threaded block is movably sleeved on the outside of the sliding rod.

[0010] Furthermore, a silicone pad is fixedly connected to the outer surface of the clamp.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This grinding equipment for processing metal stamping parts uses an electromagnetic chuck to attract the metal stamping parts and a clamping assembly to hold the ground metal stamping parts. With the help of a second electric push rod, rack and pinion, and gear, the rotating frame drives the metal stamping parts to rotate 180 degrees. Thus, the electromagnetic chuck fixation replaces the clamping fixation, so that the metal stamping parts are not obstructed during clamping and it is easy to flip the metal stamping parts, which greatly improves the grinding efficiency.

[0013] 2. This grinding equipment for processing metal stamping parts uses a second motor to drive the lead screw to rotate and move the threaded block, which in turn causes the connecting plate to move two sets of metal stamping parts. This allows the un-grinded metal stamping parts to be moved to the grinding area for alternating grinding, improving the continuity of grinding and further increasing grinding efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] Please refer to the following: Figures 1-4This utility model provides a technical solution: a grinding device for processing metal stamping parts, including a grinding table 1 and a connecting plate 2. Two first electric push rods 3 are fixedly connected to the top outer surface of the connecting plate 2. Electromagnetic chucks 4 are installed at the output ends of the first electric push rods 3. Two vertical plates 5 are fixedly connected to the top outer surface of the connecting plate 2. Support shafts are rotatably connected to the outer surfaces of the two vertical plates 5. Rotating frames 6 are fixedly connected to the outer surfaces of the support shafts. Second electric push rods 7 are fixedly installed on the outer surfaces of the vertical plates 5. Racks 8 are fixedly connected to the output ends of the second electric push rods 7. Gears 9 are fixedly sleeved on the outer surface of the support shaft. The racks 8 and gears 9 are movably meshed. Clamping components are provided on both sides of the top outer surface of the rotating frame 6. Specifically, the metal stamping parts to be ground are placed on the electromagnetic chucks 4 and fixed by the electromagnetic chucks 4. The first electric push rods 3 drive the electromagnetic chucks 4 to move and adjust the grinding position of the metal stamping parts. The grinding height is controlled by the fifth electric push rod 17, which drives the grinding disc 19 to contact the surface of the metal stamping part. The first motor 18 drives the grinding disc 19 to rotate, grinding the surface of the metal stamping part. The first electric slide rail 15 and the second electric slide rail 16 work together to grind the surface of the metal stamping part from all directions. After one side is ground, the metal stamping part is clamped by the clamping assembly. After being fixed, the second electric push rod 7 drives the rack 8 to move (the moving distance is L, L=π*r, where r is the radius of the gear 9). The rack 8 meshes with the gear 9, driving the support shaft to rotate, thereby driving the rotating frame 6 to rotate 180 degrees, flipping the metal stamping part, and grinding the other side. The electromagnetic chuck 4 is used to fix the part instead of the clamp, so that the metal stamping part is not obstructed during clamping and it is easy to flip the metal stamping part, which greatly improves the grinding efficiency.

[0021] In this embodiment, two support plates are fixedly connected to the top outer surface of the grinding table 1, and a lead screw 20 is rotatably connected between the two support plates. A second motor 21 is fixedly installed on the outer surface of one of the support plates, and the output end of the second motor 21 is fixedly connected to the lead screw 20. A threaded block 22 is threadedly connected to the outer surface of the lead screw 20, and the connecting plate 2 is fixedly connected to the top outer surface of the threaded block 22. Specifically, after a group of metal stamping parts is ground, the second motor 21 works, drives the lead screw 20 to rotate, and when the lead screw 20 rotates, it drives the threaded block 22 to move. The threaded block 22 drives the connecting plate 2 to move, so that the unground metal stamping parts are moved to the bottom of the grinding table for grinding. The ground metal stamping parts are then removed, thus performing alternating grinding, which improves the continuity of grinding and further improves grinding efficiency.

[0022] In this embodiment, a support frame is fixedly connected to the top outer surface of the polishing table 1. A first electric slide rail 15 is fixedly installed on the top lower outer surface of the support frame. A second electric slide rail 16 is fixedly connected to the output end of the first electric slide rail 15. A fifth electric push rod 17 is fixedly installed to the output end of the second electric slide rail 16. A first motor 18 is fixedly installed to the output end of the fifth electric push rod 17. A polishing disc 19 is fixedly connected to the output end of the first motor 18. Specifically, the fifth electric push rod 17 drives the polishing disc 19 to contact the surface of the metal stamping part. The first motor 18 drives the polishing disc 19 to rotate, polishing the surface of the metal stamping part. The first electric slide rail 15 and the second electric slide rail 16 work together to polish the surface of the metal stamping part in all directions.

[0023] In this embodiment, the clamping assembly includes side plates 10 fixed on both sides of the rotating frame 6. A third electric push rod 11 is fixedly installed on the outer surface of the side plates 10. A mounting plate 12 is fixedly connected to the output end of the third electric push rod 11. A fourth electric push rod 13 is fixedly installed on the side of the mounting plate 12 away from the rotating frame 6. A clamping plate 14 is fixedly connected to the output end of the fourth electric push rod 13. Specifically, the third electric push rod 11 moves the clamping plate 14, causing the clamping plate 14 to move above the metal stamping part. The fourth electric push rod 13 moves the clamping plate 14, causing the clamping plate 14 to contact the surface of the metal stamping part and fix it.

[0024] In this embodiment, a sliding rod is fixedly connected between the two support plates, and the threaded block 22 is movably sleeved on the outside of the sliding rod. Specifically, when the lead screw 20 rotates and drives the threaded block 22 to move, the threaded block 22 slides on the outer surface of the sliding rod, thus preventing the threaded block 22 from rotating with the lead screw 20.

[0025] In this embodiment, a silicone pad is fixedly connected to the outer surface of the clamping plate 14. Specifically, the silicone pad increases the friction between the clamping plate 14 and the metal stamping part.

[0026] Working Principle: In use, the metal stamping part to be polished is placed on the electromagnetic chuck 4 and fixed in place. The first electric push rod 3 moves the electromagnetic chuck 4 to adjust the height of the metal stamping part during polishing. The fifth electric push rod 17 then moves the polishing disc 19 to contact the surface of the metal stamping part. The first motor 18 drives the polishing disc 19 to rotate, polishing the surface of the metal stamping part. The first and second electric slide rails 15 and 16 work together to polish the surface of the metal stamping part from all angles. After one side is polished, the metal stamping part is clamped by the clamping assembly. During clamping, the third electric push rod 11 operates. The third electric push rod 11 drives the clamping plate 14 to move, so that the clamping plate 14 moves above the metal stamping part, and works through the fourth electric push rod 13. The fourth electric push rod 13 drives the clamping plate 14 to contact the surface of the metal stamping part and fix it. After fixing, the second electric push rod 7 drives the rack 8 to move (the moving distance is L, L=π*r, where r is the radius of the gear 9). The rack 8 meshes with the gear 9, driving the support shaft to rotate, thereby driving the rotating frame 6 to rotate 180 degrees, flipping the metal stamping part, and grinding the other side. Thus, the electromagnetic chuck 4 fixes the metal stamping part instead of the clamp, so that the metal stamping part is not obstructed during clamping, and it is easy to flip the metal stamping part, which greatly improves the grinding efficiency.

[0027] After a set of metal stamping parts is polished, the second motor 21 works, driving the lead screw 20 to rotate. When the lead screw 20 rotates, it drives the threaded block 22 to move, and the threaded block 22 drives the connecting plate 2 to move. The unpolished metal stamping parts are moved to the bottom of the polishing disc for polishing. The polished metal stamping parts are then removed, thus performing alternating polishing, which improves the continuity of polishing and further improves polishing efficiency.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
