Description

Technical Field

[0001] The present application relates to the technical field of grinding processing positioning, and in particular to a grinding auxiliary positioning device. Background Art

[0002] Grinding is a type of surface modification technology. It 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. The main purpose is to obtain a specific surface roughness. Grinding is often required in the processing of mechanical parts.

[0003] In the existing workpiece grinding process, it is generally necessary to use a positioning device to fix the workpiece. However, after the workpiece is fixed, the workpiece cannot be turned over or tilted. When a specific inclined surface or single-sided grinding is required and the workpiece needs to be turned over for grinding, the clamp can only be loosened, the position of the workpiece can be adjusted, and the workpiece can be re-clamped and fixed, which is not convenient enough.

[0004] Therefore, those skilled in the art provide a grinding auxiliary positioning device to solve the problems raised in the above background technology. Utility Model Content

A through hole is also opened on the cross bar, and the output shaft of the clamping cylinder passes through the through hole and is rotatably connected to a clamping block, and the two clamping blocks are used to fix the workpiece together. Two supporting cylinders are also arranged under the cross bar, and the output shafts of the supporting cylinders are connected to a supporting seat, and a hinged plate for supporting the workpiece is hingedly installed on the support seat.

[0008] By adopting the above technical solution, the clamping cylinder is set up, which can conveniently push the clamping block to slide close to the workpiece. Under the action of the two clamping blocks, the position of the center axis of the workpiece can be fixed, and the set supporting cylinder can also push the supporting seat to slide. The hinged plate on the supporting seat can support the bottom of the workpiece to ensure that the workpiece remains stable. When the output length of the two supporting cylinders is changed, the inclination of the workpiece can be adjusted. In addition, the supporting cylinder can be retracted and the workpiece can be flipped. After flipping, the supporting cylinder can continue to be adjusted to support the workpiece, which is more convenient during processing.

[0009] Preferably, the clamping block is clamped at the center of the workpiece, and the two hinged plates are symmetrically arranged about the center axis of the workpiece.

[0010] By adopting the above technical solution and arranging the two hinge plates symmetrically about the central axis of the workpiece, the workpiece can be kept stable.

[0011] Preferably, the clamping block is in a U-shaped structure, and clamping bolts are threadedly connected and penetrated on both upper and lower sides of the clamping block, and a pressure plate is also provided at the end of the clamping bolt.

[0012] By adopting the above technical solution, through the cooperation of the clamping bolt and the clamping block, the pressure plate can be pushed to squeeze on the workpiece, so as to facilitate the fixation of the workpiece.

[0013] Preferably, a moving frame is slidably sleeved on the support frame, and the clamping cylinder is fixedly mounted on the moving frame by screws.

[0014] By adopting the above technical solution and by providing a shift frame, the clamping cylinder can be conveniently slidably installed on the support frame, so that the position of the clamping cylinder can be conveniently adjusted.

[0015] Preferably, both sides of the moving frame are threadedly connected with adjusting bolts, and the adjusting bolts cooperate with the supporting frame.

[0016] By adopting the above technical solution, the arranged adjusting bolts can be squeezed and matched with the supporting frame, so that the moving frame can be locked.

Under the action of the two clamping blocks, the position of the center axis of the workpiece can be fixed, and the supporting cylinder can also push the supporting seat to slide. The hinged plate on the supporting seat can support the bottom of the workpiece to ensure that the workpiece remains stable. When the output length of the two supporting cylinders is changed, the inclination of the workpiece can be adjusted.

Two supporting cylinders 5 are also arranged below the cross bar 1, and a supporting seat 6 is connected to the output shaft of the supporting cylinder 5. A hinged plate 7 for supporting the workpiece is hingedly installed on the support seat 6, and the clamping block 4 is clamped at the center position of the workpiece, and the two hinged plates 7 are symmetrically arranged about the central axis of the workpiece. By symmetrically arranging the two hinged plates 7 about the central axis of the workpiece, the workpiece can be kept stable;

[0027] By setting the clamping cylinder 3, the clamping block 4 can be easily pushed to slide close to the workpiece. Under the action of the two clamping blocks 4, the position of the center axis of the workpiece can be fixed, and the set supporting cylinder 5 can also push the supporting seat 6 to slide. The hinged plate 7 on the supporting seat 6 can support the bottom of the workpiece to ensure that the workpiece remains stable. When the output length of the two supporting cylinders 5 is changed, the inclination of the workpiece can be adjusted. In addition, the supporting cylinder 5 can be retracted and the workpiece can be flipped. After flipping, the supporting cylinder 5 can continue to be adjusted to support the workpiece, which is more convenient during processing.

[0028] In the present application, the clamping block 4 is in a U-shaped structure, and the upper and lower sides of the clamping block 4 are threadedly connected and penetrated with clamping bolts 8, and the end of the clamping bolt 8 is also provided with a pressure plate 9.
