Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to Figures 1-4, an embodiment provided by the present utility model:

A machine tool fixture based on machining, comprising a fixed platform 1, a receiving groove 11 is opened inside the fixed platform 1, a reverse screw 15 is installed inside the receiving groove 11, and the left end of the reverse screw 15 extends to the fixed platform. 1 Outside, the left side of the reverse screw 15 is connected with the screw handle 4, and the fixed platform 1 at the bottom end of the reverse screw 15 is provided with a chute 10, and the number of the chute 10 is two. There is a fixed clamping plate 2, and the fixed clamping plate 2 is sleeved on the reverse screw 15, the opposite side of the fixed clamping plate 2 is installed with a connecting and fixing block 12, and the other side of the connecting and fixing block 12 is installed with The movable block 13, the other end of the movable block 13 is connected with a fixed fixture 14, and the movable upper socket block 3 makes the surface of the screw handle 4 in contact with the product appear less curved or inclined, so that the fixed fixture 14 can be The clamping of the product is more firm, the error during processing is reduced, and the machining accuracy of the machine tool is improved. At the same time, the sliding of the fixed clamping plate 2 in the chute 10 reduces the frictional force during the movement of the fixed clamping plate 2, so that the staff is in the process of moving. When turning the screw handle 4, it can save more labor, which reduces the labor intensity of the staff to a certain extent.

The front of the fixed platform 1 is fixedly installed with an upper socket block 3 , the bottom end of the upper socket block 3 is socketed with a lower socket rod 5 , and the upper socket block 3 extends to the front of the inner side of the lower socket rod 5 evenly opened. There is an adjustment screw hole 7, the front thread of the lower socket rod 5 is installed with an adjustment screw 6, and the adjustment screw 6 and the adjustment screw hole 7 cooperate with each other, the bottom end of the lower socket rod 5 is fixedly installed with a lower fixing plate 8, and the lower part is fixed The bottom end thread on the left side of the plate 8 is installed with fixing screws 9, and the number of fixing screws 9 is two. The staff adjusts the height of the device by adjusting the screws 6, so that the device can adapt to most of the The processing position of the machine tool enables the factory to restart the processing of the machine tool without the need for the original processing fixture after the original machine tool configuration fixture is damaged, which improves the processing efficiency of the machine tool. 9 to further fix the device to prevent the whole device from shaking in the subsequent machining process of the machine tool, which may lead to machining errors and reduce the machining accuracy of the machine tool.

Working principle: The staff fixes the device at the position of the machine tool by fixing the groove at the bottom end of the platform 1, and then the staff further fixes the device through the fixing screw 9 to prevent the machine tool from being processed later. The whole device shakes, which may lead to machining errors during processing, which reduces the machining accuracy of the machine tool. Pull the lower socket rod 5 to expand the clamping range of the device, and fix the device after the height adjustment is completed by adjusting the screw 6, so that the device can adapt to most of the machine tool processing positions on the market, so that the factory is in the original position. After the machine tool configuration fixture is damaged, it can be restarted through the device without the need for the original processing fixture, which improves the processing efficiency of the machine tool. The fixed clamping plates 2 move to the middle and clamp the product in the middle, so that the machine tool can clamp the product, and at the same time, in order to prevent the product from contacting the fixed fixture 14 due to the difference in the shape of the product. There is an arc or an inclined plane, so the movable movable block 13 can adjust the fixing fixture 14 at multiple angles, so that the surface of the fixing fixture 14 in contact with the product is less curved or inclined, so that the fixing fixture 14 can adjust the product to the product. The clamping of the fixed clamping plate 2 is more firm, the error during processing is reduced, and the machining accuracy of the machine tool is improved. At the same time, the sliding of the fixed clamping plate 2 in the chute 10 reduces the frictional force during the movement of the fixed clamping plate 2, so that the staff can rotate the screw while rotating the screw. When the handle is 4, it can be more labor-saving, which reduces the labor intensity of the staff to a certain extent.
