Description

Technical Field

[0001] The utility model relates to the technical field of positioning fixtures, in particular to a positioning 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. A fixture refers to a device used to fix the object to be processed during the mechanical manufacturing process so that it occupies the correct position for construction or inspection. It is also called a fixture. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process in the process can be called a fixture.

[0003] When currently used, the existing fixtures will face parts of various sizes, so the fixtures need to be replaced frequently in order to clamp the parts. This takes time to fix and install the fixture itself, which will affect the processing speed. Therefore, a positioning fixture for a grinder is proposed to solve the above problem.

[0026] When in use: when it is necessary to clamp a part, the part is placed between the two clamping plates 13, and then the electric push rod 4 is started to drive the push plate 5 to move forward. Because the other side of the push plate 5 is fixedly connected to one side of the second tooth plate 11, the push plate 5 can drive the second tooth plate 11 to move synchronously when it moves, so that the second tooth plate 11 drives the gear 7 to rotate when it moves, and then the first tooth plate 10 moves along the direction of rotation of the gear 7. When the first tooth plate 10 and the second tooth plate 11 move relative to each other, the two clamping plates 13 are driven to approach each other, so that the clamping of the part can be completed, and the side where the two clamping plates 13 are close to each other is provided with a protective pad 14, which can protect both sides of the part and prevent the part from sliding during processing. The electric push rod 4 can The position of the second tooth plate 11 can be adjusted, so that the distance between the two clamping plates 13 can also be adjusted accordingly, which is convenient for clamping parts of different sizes. After clamping, the grinding machine can be used for processing. When the parts are grinded, a lot of debris will be generated. At this time, the suction nozzle 22 is driven to move to one side of the processing location by pulling the hose 21, and then the vacuum cleaner 18 is started to suck some debris into the collection box 17 through the suction nozzle 22 to avoid excessive accumulation of debris that will affect normal processing. The filter screen 20 is set to prevent the debris from entering the vacuum cleaner 18 along the connecting pipe 19, thereby causing damage to the parts inside the vacuum cleaner 18. After the grinding machine is finished, the box cover on the top side of the collection box 17 can be taken out, and then the debris in the collection box 17 can be uniformly recycled.
