Description

Technical Field

[0001] The utility model relates to the field of positioning mechanisms, in particular to a workpiece positioning mechanism for polishing equipment. Background Art

[0002] At present, a Chinese utility model with the announcement number CN219882201U discloses a workpiece fixing fixture for a polishing machine, including a first motor, a rotating cylinder installed at the output end of the first motor, a second motor installed on one side of the rotating cylinder, a first clamping plate installed at the output end of the second motor, a movable rod slidably installed on the outer side of the rotating cylinder, a connecting plate welded to one end of the movable rod, an adjustment component for driving the connecting plate to move is provided on one side of the connecting plate, and a second clamping plate is movably installed on one side of the connecting plate. The utility model facilitates the adjustment of the angle of the workpiece, facilitates the polishing of different positions of the workpiece without removing the workpiece, and can facilitate the collection and cleaning of the powder generated by polishing;

[0003] Although the existing fixing fixture can press the workpiece through the clamping plate to prevent the workpiece from shifting during the polishing process, there are still other problems in use. For example, it does not have a height adjustment function. The top position of the workpiece cannot be adjusted after it is fixed. When the position of the workpiece after fixation is lower than the polishing wheel on the polishing equipment, it cannot be contacted due to deviation. The flexibility is poor and it is not convenient to flip the polished surface of the workpiece. After polishing one side of the workpiece, personnel are required to loosen the clamping plate, then pick up the workpiece, flip it over and put it back in, and finally move and clamp the clamping plate again, which reduces the processing efficiency of the workpiece and has low practicality. In order to solve the above-mentioned problems, we propose a workpiece positioning mechanism for polishing equipment. Utility Model Content

[0004] The utility model aims to provide a workpiece positioning mechanism for polishing equipment, which solves the problem that the existing workpiece positioning mechanism has no height adjustment function and is inconvenient to turn over the workpiece.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a workpiece positioning mechanism for a polishing equipment, comprising a base, a first mounting frame welded on the top of the base, a bearing seat arranged on the top of the base, a second mounting frame welded on the bottom of the bearing seat, first screw rods symmetrically welded on both sides of the first mounting frame, a fixing nut is threadedly connected to the surface of the first screw rod, sliding grooves are provided on both sides of the second mounting frame, a fixing frame is placed on the top of the bearing seat, a clamping mechanism is arranged inside the fixing frame, limiting blocks are symmetrically welded on the front and back sides of the fixing frame, and a limiting groove used in conjunction with the limiting block is provided on the top of the bearing seat.

[0006] The above technical solution can have a height adjustment function, can be appropriately adjusted according to the position of the polishing wheel, has good flexibility, and can facilitate flipping of the workpiece, is simple and labor-saving to operate, improves the processing efficiency of the workpiece, and is highly practical.

[0007] The utility model is further configured as follows: the clamping mechanism includes a clamping plate, the number of the clamping plates is two, the two clamping plates are rotatably connected to the back-to-back sides with a second screw rod, the other end of the second screw rod passes through the outside of the bearing seat and is welded with a turning handle, and threaded grooves are provided on both sides of the bearing seat.

[0008] By adopting the above technical solution, the clamping plate, the second screw rod, the turning handle and the threaded groove are arranged, so that the workpiece can be clamped and fixed in cooperation with the bearing seat, thereby preventing the workpiece from shifting during polishing.

[0009] The utility model is further configured as follows: the two clamping plates are symmetrically welded with limiting rods on one side facing away from the other, and the other end of the limiting rod passes through and extends to the outside of the bearing seat.

[0010] By adopting the above technical solution, the clamping plate can be limited by setting the limiting rod to prevent the clamping plate from rotating during the process of moving left and right.

[0011] The utility model is further configured as follows: a mounting hole is provided on the top of the base.

[0012] By adopting the above technical solution, through the provision of the mounting holes, it is convenient for personnel to fix the base with screws, thus reducing the trouble of temporary drilling.

[0013] The utility model is further configured as follows: the first screw rod and the fixing nut are both made of stainless steel.

[0014] By adopting the above technical solution, the first screw rod and the fixing nut have the characteristics of high strength, low density and excellent corrosion resistance.

[0015] The utility model is further configured as follows: surfaces of the base, the first installation frame, the bearing seat, the second installation frame and the fixing frame are all coated with anti-corrosion paint.

[0016] By adopting the above technical solution and providing the anti-corrosion coating, the anti-corrosion effect of the surfaces of the base, the first mounting frame, the bearing seat, the second mounting frame and the fixing frame can be improved, thereby extending their service life.

[0017] In summary, the utility model has the following beneficial effects:

[0018] 1. The utility model first fixes the base on the moving table of the polishing equipment with screws, and then loosens the fixing nut with a tool. After the fixing nut is loosened, the fixing of the first screw rod and the second installation frame is released. Then, a person grabs the bearing seat to drive the second installation frame to move upward. When the bearing seat moves to a suitable position, the fixing nut is tightened again. The utility model has a height adjustment function, which can be appropriately adjusted according to the position of the polishing wheel, and has good flexibility.

[0019] 2. The utility model places the workpiece into the fixed frame, and after the workpiece is placed in, the handle is held to drive the second screw to rotate. When the second screw rotates, the clamping plate will move inward to clamp the workpiece. When the single-side polishing of the workpiece is completed, the handle is held by hand to lift the fixed frame upward. After lifting, the fixed frame is turned over a circle so that the bottom of the workpiece faces upward, and finally the limit groove on the fixed frame is put back into the limit groove, which can facilitate the flipping of the workpiece. The operation is simple and labor-saving, which improves the processing efficiency of the workpiece and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
