Description

Technical Field

[0001] The utility model relates to the technical field of grinding fixtures, in particular to a grinding fixture for a grinding machine. Background Art

[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use a high-speed rotating grinding wheel for grinding. Grinding machines can process materials with higher hardness, such as hardened steel, cemented carbide, etc., and can also process brittle materials, such as glass and granite. Grinding machines can perform high-precision grinding with very small surface roughness and are widely used in various fields. Existing grinders need to be used with a fixture when in use, and the fixture is used to firmly clamp the workpiece to prevent the workpiece from shifting during the grinding process and affecting the processing accuracy.

[0003] For example, CN212947244U is a grinding fixture for a cylindrical grinder. This utility model sets a permanent magnetic adsorption component and uses the changes in the magnetic flux lines of two groups of permanent magnets inside the permanent magnetic adsorption component to quickly achieve magnetic fixation and unlocking of the workpiece. It uses neodymium iron boron permanent magnets as the magnetic source, and can fix the cylindrical grinding workpiece without contact, making it convenient for the grinder cutting component to grind the outer periphery of the processing shaft. It has a simple structure and is easy to use.

[0004] However, the above-mentioned prior art still has the following problems when in use: the existing fixtures are usually clamped at both ends of the workpiece to clamp the workpiece. When the end face of the round rod-shaped workpiece needs to be processed, the contact between the fixture and the outer wall of the round rod-shaped workpiece is easily offset, which in turn affects the grinding effect. Based on this, the utility model provides a grinding fixture for a grinder with adjustable workpiece clamping position and a wide grinding range. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a grinding fixture for a grinder to meet the processing requirements of different workpieces and ensure the grinding effect of the workpieces.

[0010] A first motor for driving the bidirectional lead screw to rotate is fixed inside the base. The first motor is used to drive the two nut blocks to move, adjust the distance between the two support blocks, and thus clamp the workpiece to be ground.

[0011] In a preferred embodiment, two insertion slots are provided at the tops of the two first clamping blocks and the two second clamping blocks. Spring pins adapted to the insertion slots are inserted into the top of the support block. The spring pins are inserted into the insertion slots to fix the first clamping block or the second clamping block, and at the same time facilitate the disassembly of the first clamping block and the second clamping block.

[0012] In a preferred embodiment, limiting blocks are respectively fixed at the bottoms of the two first clamping blocks and the two second clamping blocks. Limiting grooves adapted to the limiting blocks are provided on the inner walls of the bottoms of each embedding groove. The limiting blocks are slidably arranged in the limiting grooves. The limiting blocks and the limiting grooves are used to assist in positioning the first clamping block and the second clamping block, and facilitate the disassembly and assembly of the first clamping block and the second clamping block with the embedding groove.

[0013] In a preferred embodiment, the adjusting assembly includes a fixing plate. A U-shaped plate is fixed to the front end of the fixing plate. A rotating rod is rotatably arranged in the U-shaped plate. A connecting block is fixedly sleeved on the rotating rod. A second motor for driving the rotating rod to rotate is fixed to the front end of the U-shaped plate. The second motor is used to drive the vertical plate to drive the base to rotate, so as to adjust the angle of the base.

[0014] In a preferred embodiment, a third motor for driving the vertical plate to rotate is fixed to one side of the connecting block. The angle of the base is adjusted by means of the third motor, which is more time-saving and labor-saving in use.

[0015] In a preferred embodiment, a plurality of mounting holes are provided on the fixing plate, which is convenient for mounting the fixing plate on the grinding machine.

[0016] The technical effects and advantages of the present utility model:

[0017] 1. Drive the bidirectional lead screw to rotate through Motor 1, thereby driving two Clamping Blocks 1 to move towards each other through the nut block to clamp the outside of the workpiece.
