Description

Technical Field

[0001] The utility model relates to the technical field of surface grinder positioning, in particular to a surface grinder positioning mechanism. Background Art

[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece, and a surface grinder is a type of grinder. It mainly uses a grinding wheel to rotate and grind the workpiece to achieve the required flatness. According to the shape of the worktable, it can be divided into two types: rectangular worktable and circular worktable. The main parameters of a rectangular worktable surface grinder are the width and length of the worktable, and the main parameter of a circular worktable is the diameter of the worktable surface. When a surface grinder processes a workpiece, it is necessary to position the workpiece. This can effectively prevent the workpiece from shaking during processing, reduce processing errors, and thus improve the accuracy of workpiece processing.

[0003] However, in the prior art, when processing metal plates, surface grinders often use electromagnets to adsorb and fix the metal plates. This method cannot stably fix the metal plates, and displacement may occur during processing, resulting in the inability to process them. Moreover, when processing metal plates, surface grinders will not only move in the horizontal plane, but will also be slightly displaced in the vertical direction due to vibration, thereby affecting the processing accuracy of the metal plates.

[0004] Therefore, a surface grinder positioning mechanism is proposed to solve the above problems. Utility Model Content

[0030] In one embodiment, the two fixing components 5 include two transverse grooves 501, and the two transverse grooves 501 are symmetrically opened on the top surface of the surface grinder worktable 1. The inner wall surface of one side of the two transverse grooves 501 is fixedly installed with a second motor 502, and the inner wall surface of the other side of the two transverse grooves 501 is connected with a bidirectional threaded rod 503 through a bearing, one end of the two bidirectional threaded rods 503 is fixedly connected to the output end of the two second motors 502, and the surface of the two bidirectional threaded rods 503 is threadedly connected with two movable blocks 504.

[0033] Specifically: the turntable 509 drives the fastening bolts 508 to rotate, and the plurality of fixing plates 510 cooperate with the surface grinder workbench 1 to prevent the metal plate from being displaced in the vertical direction.

[0034] Working principle: When the surface grinder processes metal sheets, the metal sheets need to be fixed on the surface of the surface grinder worktable 1 to ensure that no displacement occurs during processing of the metal sheets. When the metal sheets need to be fixed on the surface of the surface grinder worktable 1, firstly, the first motor 410 is operated through the control button 2. The operation of the first motor 410 drives the rotating rod 409 to rotate. The rotation of the rotating rod 409 drives the gear 411 to rotate. The rotation of the gear 411 and the two racks 407 mesh with each other, so that the two racks 407 move in the direction away from each other inside the two T-shaped slides 406. The two racks 407 move in the direction away from each other inside the two T-shaped slides 406, driving the two connecting plates 405 to move in the direction away from each other. The two connecting plates 405 move in the direction away from each other, driving the two U-shaped plates 403 on the two support rods. The surfaces of the two U-shaped plates 402 move in a direction away from each other. When the distance between the two U-shaped plates 403 is greater than the length of the metal sheet, the metal sheet to be processed is placed between the two U-shaped plates 403. Then, the first motor 410 is operated in the reverse direction by controlling the button 2, so that the rotating rod 409 is reversed, and the two U-shaped plates 403 move in a direction close to each other. When the anti-slip strips 404 on the surfaces of the two U-shaped plates 403 can firmly clamp the metal sheet to a limited position, the first motor 410 can be stopped to complete the purpose of fixing the metal sheet on the surface of the surface grinder workbench 1. Through the cooperation of the above structure, the two U-shaped plates 403 clamp and fix the metal sheet, and can firmly fix metal sheets of different sizes on the surface of the surface grinder workbench 1, so as to avoid displacement of the surface grinder when processing the metal sheet.When it is necessary to fix the metal sheet in the vertical direction, the metal sheet is clamped and fixed on the surface of the surface grinder worktable 1 in advance by the clamping assembly 4, and then the two second motors 502 are operated by the controller. The operation of the second motors 502 drives the two bidirectional threaded rods 503 to rotate, and the rotation of the two bidirectional threaded rods 503 drives multiple movable blocks 504 to move in a direction approaching each other in groups of two, and the multiple movable blocks 504 move in a direction approaching each other in groups of two, driving multiple hinged plates 505 to move, and the movement of multiple hinged plates 505 drives the two long plates 506 to move. When the two long plates 506 are located at the two side edges of the metal sheet and not above the metal sheet, the two second motors 502 are stopped and the multiple movable plates 507 are rotated. The rotation of the multiple movable plates 507 drives the multiple fastening bolts 508 to move, and the movement of the multiple fastening bolts 508 drives the multiple The plurality of rotating disks 509 and the fixed plate 510 move. When the fixed plate 510 is completely located above the metal sheet, the movable plate 507 is stopped and the plurality of rotating disks 509 are rotated. The rotation of the plurality of rotating disks 509 drives the plurality of fastening bolts 508 to rotate. The rotation of the plurality of fastening bolts 508 drives the plurality of fixed plates 510 to move. When the plurality of fixed plates 510 cooperate with the surface grinder workbench 1 to firmly fix the metal sheet, the plurality of rotating disks 509 can be loosened to complete the vertical fixation of the metal sheet. Through the cooperation of the above structure, the plurality of fixed plates 510 cooperate with the surface grinder workbench 1 to fix the metal sheet in the vertical direction, and the position of the plurality of fixed plates 510 can be adjusted according to the metal sheets of different sizes, which effectively prevents the surface grinder from vertically displacing when processing the metal sheet, thereby affecting the processing accuracy of the metal sheet. ;
