Description

Technical Field

[0001] The utility model relates to the technical field of metal part grinding, in particular to a grinding device for metal part processing. Background Art

[0002] Grinding is a type of surface modification technology, which generally refers to a processing method that uses rough objects (such as sandpaper containing high-hardness particles) to change the physical properties of the material surface through friction. In the production process of metal parts, the surface of the metal parts needs to be polished to facilitate subsequent surface processing of the metal parts.

[0003] Most of the current methods for polishing metal parts use a polishing device to clamp and fix the metal parts, and polish the surface of the metal parts by rotating the polishing disc. However, the traditional polishing device can only polish one side of the metal part when fixing and polishing the metal part. If the metal part needs to be turned over, the worker needs to remove the metal part after polishing one side, turn it over and re-fix it, and then continue the polishing work, which is cumbersome. Therefore, we have proposed the utility model to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a grinding device for metal parts processing, which is used to solve the above problems.

The turntable is rotatably installed in the side opening of the U-shaped frame, and one end of the bidirectional threaded rod is fixedly installed on one side of the turntable. The other end of the bidirectional threaded rod is threaded through the outside of the corresponding two clamping plates and rotatably installed on one side inner wall of the corresponding mounting groove; through two sets of clamping adjustment mechanisms, the two sets of clamping plates can clamp and fix the metal parts.

[0008] Preferably, the bottom side of the U-shaped frame rolls and fits on multiple conveying rollers, and the bottom sides of multiple clamping plates roll and fit on multiple conveying rollers; thus, the U-shaped frame rolls on multiple conveying rollers.

[0009] Preferably, the flipping mechanism includes a semicircular frame, a column groove and a guide groove. The semicircular frame is fixedly installed at the flipping mouth of the polishing table body. Two column grooves are respectively provided on the semicircular frame. Guide grooves are provided on the inner walls on both sides of the semicircular frame. The guide grooves are connected to the two column grooves; this facilitates the flipping of the U-shaped frame in the semicircular frame.

[0010] Preferably, the side column is adapted to the column groove, and the guide protrusion is adapted to the guide groove; when the U-shaped frame is flipped, the two guide protrusions at both ends of the side column are respectively in the corresponding guide grooves until the side column is flipped 180 degrees and inserted into another column groove on the semicircular frame.

[0011] Preferably, the grinding mechanism includes a mounting frame, an electric push rod, a grinding wheel and a motor, and the same mounting frame is movably connected to multiple fixed rods, and two electric push rods are fixedly installed on the bottom side of the top frame, and the output ends of the two electric push rods are fixedly installed on the top side of the mounting frame. A grinding wheel is rotatably installed on the inner wall of the mounting frame, and a motor is fixedly installed on one side of the mounting frame, and the output end of the motor is fixedly installed on one side of the grinding wheel; by starting the two electric push rods and the motor, the rotating grinding wheel is driven to move downward to achieve grinding of the clamped metal parts.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The grinding device for processing metal parts uses two sets of clamping adjustment mechanisms to enable two sets of clamping plates to clamp and fix the metal parts in a U-shaped frame, and the grinding mechanism is used to grind one side of the metal part.

[0022] Furthermore, the clamping and adjusting mechanism includes a turntable 9 and a bidirectional threaded rod 10. The turntable 9 is rotatably installed in the side opening 8 on the U-shaped frame 5, and one end of the bidirectional threaded rod 10 is fixedly installed on one side of the turntable 9. The other end of the bidirectional threaded rod 10 is threaded through the outside of the corresponding two clamping plates 7 and is rotatably installed on one side inner wall of the corresponding mounting groove 6; through two sets of clamping and adjusting mechanisms, the two sets of clamping plates 7 can clamp and fix the metal parts.

[0023] Specifically, the bottom side of the U-shaped frame 5 rolls and fits on the multiple conveying rollers 2 , and the bottom sides of the multiple clamping plates 7 roll and fit on the multiple conveying rollers 2 ; thus, the U-shaped frame 5 rolls on the multiple conveying rollers 2 .

[0024] Furthermore, the flipping mechanism includes a semicircular frame 13, a column groove 14 and a guide groove 15. The semicircular frame 13 is fixedly installed at the flipping mouth 3 on the polishing table body 1. Two column grooves 14 are respectively provided on the semicircular frame 13. Guide grooves 15 are provided on the inner walls on both sides of the semicircular frame 13. The guide grooves 15 are connected to the two column grooves 14; this facilitates the flipping of the U-shaped frame 5 in the semicircular frame 13.

[0025] Specifically, the side column 11 is adapted to the column groove 14, and the guide protrusion 12 is adapted to the guide groove 15; when the U-shaped frame 5 is flipped, the two guide protrusions 12 at both ends of the side column 11 are respectively in the corresponding guide grooves 15, until the side column 11 is flipped 180 degrees and inserted into the other column groove 14 on the semicircular frame 13.

[0026] Furthermore, the grinding mechanism includes a mounting frame 18, an electric push rod 19, a grinding wheel 20 and a motor 21.

[0027] During use: When grinding metal parts, the staff places the metal parts on the multiple conveying rollers 2 on the right side of the grinding table 1. At this time, the metal parts are located in the U-shaped frame 5. Then, by screwing the two turntables 9, the two bidirectional threaded rods 10 are synchronously driven to rotate, and then the two sets of clamping plates 7 are synchronously driven to slide in the corresponding mounting grooves 6 and approach each other. The metal parts are clamped and fixed by the two sets of clamping plates 7. After that, the staff holds the side column 11 on one side of the U-shaped frame 5 and pushes the U-shaped frame 5 to move in the direction of the grinding wheel 20. At the same time, by starting the two electric push rods 19 and the motor 21, the rotating grinding wheel 20 is driven Move downward to grind the top and side surfaces of the clamped metal part. After pushing the metal part to the left to complete the grinding operation of the top and side surfaces, continue to push the U-shaped frame 5 to the left so that the side column 11 on one side of the U-shaped frame 5 is inserted into the corresponding column groove 14 on the semicircular frame 13. Then, flip the U-shaped frame 5 to 180 degrees so that the two guide protrusions 12 at both ends of the side column 11 are respectively in the corresponding guide grooves 15, until the side column 11 is flipped 180 degrees and inserted into the other column groove 14 on the semicircular frame 13, thereby completing the 180-degree flipping of the clamped metal part. Afterwards, push the U-shaped frame 5 to the right to grind the other side of the metal part.

[0028] To sum up, the grinding device for metal parts processing in this case uses two sets of clamping adjustment mechanisms to enable two sets of clamping plates 7 to clamp and fix the metal parts in the U-shaped frame 5, and grinds one side of the metal parts through the grinding mechanism. After that, when the U-shaped frame 5 moves to the semicircular frame 13, the clamped and fixed metal parts can be flipped 180 degrees, completing the flipping of the clamped and fixed metal parts, which is convenient for grinding the other side of the metal parts. The method of grinding both sides of the metal parts in this case avoids the need to remove the clamped and fixed metal parts and then re-clamp and fix them. The operation is simple and fast, which improves the practicality of the grinding device for metal parts processing.
