Description

Technical Field

[0001] The present application relates to the technical field of surface grinders, and specifically discloses a grinding device for processing metal parts. Background Art

[0002] A grinder, as a mechanical tool mainly used for processing various metals and non-metals, is mainly used for grinding and machining the surface of workpieces so that the workpieces meet the requirements of predetermined dimensions and surface quality.

[0003] In the prior art, such as the full-automatic surface grinder disclosed in Chinese Patent Publication No. CN221159648U, mainly includes a grinder body and an omnidirectional moving workbench installed on the grinder body. The second motor installed on the omnidirectional moving workbench drives the lead screw to rotate, and the synchronous movement of the first telescopic frame and the second telescopic frame on both sides is driven by the rotation of the lead screw. The first telescopic frame and the second telescopic frame are both installed in a threaded connection manner with the lead screw.

[0004] The parts to be ground are fixed by the first main clamp and the second main clamp installed on the first telescopic frame and the second telescopic frame. During the grinding process of the parts, the parts are ground by the grinding wheel installed in the grinder body, and the parts can be rotated for circumferential grinding.

[0005] However, during use, since both the first telescopic frame and the second telescopic frame are threadedly connected to the lead screw, when any one of the first telescopic frame and the second telescopic frame slips, the parts will be misaligned or unable to move, thereby affecting the grinding effect and being inconvenient to use.

[0006] Therefore, in view of this, the inventor provides a grinding device for processing metal parts to solve the above problems. Summary of the Utility Model

[0007] The purpose of the present utility model is to solve the problem that in the process of using a traditional grinder, the two ends of the parts are respectively fixed by telescopic frames threadedly connected to the lead screw. When any one of the telescopic frames fails, the parts will be offset or unable to move, affecting the grinding effect of the parts.

[0008] To achieve the above object, the basic solution of the present utility model provides a grinding device for processing metal parts, including a grinding machine body and a movable workbench arranged on the grinding machine body. A receiving groove is formed on the surface of the movable workbench. A support table is slidably connected in the receiving groove. End bottom tables are respectively slidably connected to both sides of the support table. Fixing members for fixing the end bottom tables on the same side are respectively arranged on both sides of the support table. Vertical plates are arranged on the end bottom tables. End clamping members are rotatably connected to the vertical plates. A driving motor I for driving the rotation of the end clamping members is also arranged on a vertical plate on one side in the receiving groove. A driving structure for driving the support table to slide along the receiving groove is also arranged in the receiving groove.

[0009] Further, the driving structure includes a lead screw rotatably connected in the receiving groove and a driving motor II fixed on one side of the movable workbench and used for driving the rotation of the lead screw. An internal thread hole threadedly connected to the lead screw is formed on the support table.

[0010] Further, the outer walls on both sides of the end bottom table are respectively attached to the inner walls on both sides of the receiving groove, and a through hole for the lead screw to pass through is formed on the end bottom table.

[0011] Further, connecting rods slidably connected to the support table and fixed by the fixing members are arranged on the end bottom tables. The connecting rods on the end bottom tables on both sides of the support table are arranged staggeredly.

[0012] Further, the end clamping member includes a transmission shaft rotatably connected to the vertical plate, a turntable fixed on the transmission shaft, and main clamping plates respectively fixed on both sides of the turntable. The same ends of the main clamping plates on both sides incline inwards. A sub-clamping plate for clamping and fixing the end of the workpiece is detachably connected between the main clamping plates on both sides.

[0013] Further, sliding grooves are formed on the main clamping plates. Connecting holes opposite to the sliding grooves are formed at both ends of the sub-clamping plate. A screw rod passing through the connecting holes and extending out of the sliding grooves on the same side is arranged on the sub-clamping plate. A nut is threadedly connected to the end of the screw rod extending out of the sliding groove.

[0014] Further, a plurality of anti-slip rib strips are equidistantly arranged on the inner side of the main clamping plate.

[0015] The principle and effect of this solution are as follows:

[0016] 1. Compared with the prior art, the support table installed in the movable workbench of the present utility model mainly performs the function of driving the support table to move through the driving structure to control the movement of the workpiece installed between the end clamping members on both sides, so as to control the position of the workpiece in the plane. By driving the rotation of one side of the end clamping member by the driving motor I, the workpiece and the end clamping member on the other side are driven to rotate synchronously, so that the workpiece can be circumferentially ground by the grinding machine body.

[0017] 2. Compared with the prior art, the driving structure of the present utility model only drives the support table to move, reducing the probability that the workpiece in the moving workbench cannot move, reducing the failure rate of the moving workbench. At the same time, the length of the workpiece that can be installed can be adjusted by adjusting the positions of the bottom tables at both ends of the support table, and workpieces of different sizes can be installed, solving the problem that in the traditional grinding machine during use, both ends of the parts are fixed by telescopic frames threadedly connected to the lead screw. When any one of the telescopic frames fails, the parts will be offset or unable to move, affecting the grinding effect of the parts. BRIEF DESCRIPTION OF THE DRAWINGS
