Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a grinding and polishing device for metal processing. Background Technology

[0002] When sheet metal is exposed to air during storage, transportation, or processing, an oxide layer forms on its surface. For example, steel sheets are prone to rusting in humid environments, producing rust such as iron oxide. These oxide layers and rust affect the appearance of the sheet metal and the quality of subsequent processing. They can be effectively removed by grinding and polishing, restoring the smoothness and metallic properties of the metal surface.

[0003] The prior art (announcement number: CN 219255015 U) discloses a gear shaft grinding equipment for automated production, including a housing, a plurality of leakage holes at the top of the housing, a filter plate fixedly connected inside the housing, and fixed plates fixedly connected to the left and right sides of the housing. A motor is fixedly connected to the top of the two fixed plates, a movable block is fixedly connected to the drive end of the motor, a movable rod is fixedly connected to the top of the movable block, and a rotating shaft is rotatably connected to the top of the movable rod.

[0004] Although the aforementioned patent has achieved the utilization of water resources, thereby avoiding water waste and improving the utilization rate of water resources, it has the following drawbacks: during processing, other operations cannot be performed, and the disassembly and installation of workpieces can only be carried out after processing is completed. The waiting process wastes a lot of time and affects work efficiency, requiring further improvement. Therefore, a grinding and polishing equipment for metal processing is proposed. Utility Model Content

[0005] The main objective of this invention is to provide a grinding and polishing equipment for metal processing, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A metalworking grinding and polishing device includes a worktable. A rotatable disc is mounted on the upper end of the worktable. A vertical plate is mounted on the rear of the upper end of the worktable. Two first motors are symmetrically distributed front and rear on the lower end of the disc. The output ends of the two first motors are movably inserted through the upper end of the disc and fixedly connected to an electric three-jaw chuck. The clamping ends of the two electric three-jaw chucks are fixedly connected to three fixed plates arranged in a circular array. An X-axis linear module is mounted on the upper front end of the vertical plate. A support plate is mounted on the moving end of the X-axis linear module. An electric cylinder is mounted on the upper end of the support plate. The output end of the electric cylinder movably passes through the lower end of the support plate and is fixedly connected to a grinding machine. The two electric three-jaw chucks on the disc drive the workpiece to rotate sequentially to the bottom of the grinding machine to complete the grinding and polishing operation.

[0008] Preferably, a driving component is installed at the lower end of the worktable. The driving component is used to drive the disc to rotate. The driving component includes a bracket, which is installed at the lower end of the worktable. A second motor is fixedly connected to the bracket. A connecting shaft is fixedly connected to the output end of the second motor. An angle sensor is fixedly sleeved on the outer surface of the connecting shaft. The angle sensor is installed at the lower end of the worktable.

[0009] Preferably, the upper end of the connecting shaft extends movably through to the upper side of the worktable and is fixedly connected to the disc, and the lower end of the disc is fixedly connected to a support bearing, which is mounted on the worktable.

[0010] Preferably, a Z-axis linear module is installed at the front end of the vertical plate, a rotary cylinder is installed at the moving end of the Z-axis linear module, a mechanical gripper is installed at the moving end of the rotary cylinder, and a fixed clamp is fixedly connected to both gripping ends of the mechanical gripper.

[0011] Preferably, the fixing clip is located on the rear side of the rear fixing plate.

[0012] Preferably, the grinder is located above the rear-mounted electric three-jaw chuck.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By setting up a disc, an electric three-jaw chuck, and a drive unit to work together, work efficiency can be improved. When the rear gear shaft is being processed, other gear shafts that need to be ground are placed in the front electric three-jaw chuck and fixed by a fixing plate. After processing, the second motor is controlled to drive the connecting shaft to rotate, and the connecting shaft drives the disc to rotate half a turn, so that the two gear shafts are swapped. The unground gear shafts are ground, and the ground gear shafts are removed and new gear shafts are placed and fixed, which reduces time waste and increases productivity.

[0015] 2. By setting up a Z-axis linear module, a rotary cylinder, mechanical grippers, and fixed clamps working together, the gear shaft can be rotated. After the upper surface of the gear shaft is polished, the gripping end of the mechanical gripper drives the two fixed clamps to rotate forward, clamping the gear part of the gear shaft. The electric three-jaw chuck stops clamping. Then, the Z-axis linear module drives the gear shaft to move upward a certain distance. The rotary cylinder drives the gear shaft to rotate half a revolution. The Z-axis linear module drives the gear shaft to move downward, so that the polished shaft is inserted into the vertical plate. The electric three-jaw chuck re-clamps, and the gripping end of the mechanical gripper drives the two fixed clamps to reset. This allows the other surfaces of the gear shaft to be polished without the need for manual rotation by workers, reducing the number of operation steps and the amount of labor required.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figures 1-4 As shown, a metalworking grinding and polishing equipment includes a worktable 1, a rotatable disc 2 mounted on the upper end of the worktable 1, a vertical plate 7 mounted on the rear upper part of the worktable 1, an X-axis linear module 8 mounted on the upper front part of the vertical plate 7, a support plate 9 mounted on the moving end of the X-axis linear module 8, an electric cylinder 10 mounted on the upper end of the support plate 9, and the output end of the electric cylinder 10 movably passes through the lower end of the support plate 9 and is fixedly connected to a grinding machine 11. In use, the gear shaft is fixed on the disc 2, and the X-axis linear module 8 is controlled to drive the grinding machine 11 to move to the left. The grinding machine 11 grinds and polishes the rotating part of the gear shaft. The electric cylinder 10 can be controlled to drive the grinding machine 11 to move up and down. However, during processing, other operations cannot be performed. It is necessary to wait for the processing to be completed before the workpiece can be disassembled and installed. The waiting process wastes a lot of time.

[0025] To address the aforementioned drawbacks, this invention employs alternating grinding and polishing at two workstations. Specifically: two symmetrically distributed first motors 4 are mounted on the lower end of the disc 2. The output ends of both first motors 4 are movably inserted into the upper end of the disc 2 and fixedly connected to an electric three-jaw chuck 5. The clamping ends of both electric three-jaw chucks 5 are fixedly connected to three fixed plates 6 arranged in a circular array. The fixed plates 6 are used to clamp the shaft portion of the gear shaft. A drive component 3 is mounted on the lower end of the worktable 1. The drive component 3 is used to drive the disc 2 to rotate. The drive component 3 includes a bracket 31, which is mounted on the lower end of the worktable 1. A second motor 32 is fixedly connected to the bracket 31. The output end of the second motor 32 is fixedly connected to a connecting shaft 33. An angle is fixedly sleeved on the outer surface of the connecting shaft 33. Sensor 34, angle sensor 34 is used to detect the rotation angle of connecting shaft 33. The angle sensor 34 is installed at the lower end of worktable 1. The gear shaft is placed in the three fixed plates 6 on the rear side. The electric three-jaw chuck 5 on the rear side is controlled to drive the three fixed plates 6 on the rear side to move closer to each other, and fix the gear shaft for processing. When the gear shaft on the rear side is being processed, other gear shafts that need to be ground are placed in the electric three-jaw chuck 5 on the front side and fixed by the fixed plates 6. After processing is completed, the second motor 32 is controlled to drive the connecting shaft 33 to rotate. The connecting shaft 33 drives the disc 2 to rotate half a turn, so that the two gear shafts are swapped. The gear shaft that has not been ground is ground. The ground gear shaft is removed and a new gear shaft is placed and fixed, which reduces the waste of time and improves the production capacity.

[0026] The upper end of the connecting shaft 33 extends through to the upper side of the worktable 1 and is fixedly connected to the disc 2 by bolts. The lower end of the disc 2 is fixedly connected to a support bearing 12, which is installed on the worktable 1 and is used to support the rotation of the disc 2 to improve stability.

[0027] In addition, to polish other surfaces of the gear shaft, it is necessary to flange the gear shaft. For this purpose, a Z-axis linear module 13 is installed at the front end of the vertical plate 7. A rotary cylinder 14 is installed at the moving end of the Z-axis linear module 13, and a mechanical gripper 15 is installed at the moving end of the rotary cylinder 14. The gripper of the mechanical gripper 15 can open and close 180°. Both clamping ends of the mechanical gripper 15 are fixedly connected to fixing clips 16. The fixing clips 16 are used to clamp the gear shaft gear section. The fixing clips 16 are located on the rear side of the rear fixing plate 6. After the upper surface of the gear shaft is polished, the clamping ends of the mechanical gripper 15 are controlled to move... The two fixed clamps 16 rotate forward to clamp the gear shaft. The electric three-jaw chuck 5 stops clamping. Then, the Z-axis linear module 13 drives the gear shaft to move upward a certain distance. The rotary cylinder 14 drives the gear shaft to rotate half a revolution. The Z-axis linear module 13 drives the gear shaft to move downward, so that the polished shaft is inserted into the vertical plate 7. The electric three-jaw chuck 5 is then re-clamped. The clamping end of the mechanical jaw 15 drives the two fixed clamps 16 to reset. The other surfaces of the gear shaft can then be polished without the need for manual flipping, reducing the number of steps and workload for workers.

[0028] In order to be able to process the workpiece, the grinding machine 11 is located above the rear electric three-jaw chuck 5.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
