Description

Technical Field

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

[0002] A machine tool fixture is a device used to clamp workpieces and guide tools on machine tools. It refers to a fixture specially designed for a certain process of a certain workpiece. It is characterized by compact structure, quick, convenient and labor-saving operation, and can ensure high processing accuracy and production efficiency, but the design and manufacturing cycle is long and the manufacturing cost is also high. When the product is changed, the fixture will be scrapped because it can no longer be used. It is only suitable for production with fixed products and large batches. It contacts the positioning reference of the workpiece and is used to determine the correct position of the workpiece in the fixture, thereby ensuring the relative correct position of the workpiece relative to the tool and the machine tool processing movement during processing.

[0003] In the prior art, during the production process of the motor, it is often necessary to use a machine tool to process the motor parts, and during the process of the machine tool processing the motor parts, the motor parts need to be fixed on the machine tool by a clamp to ensure that there is no displacement during the processing of the motor parts and the processing effect is affected. However, during the actual use of the existing machine tool clamps, when processing motor parts of different sizes, the staff needs to use auxiliary tools to adjust the positioning pins and screws, etc., so that the clamp can adapt to the motor parts that need to be processed at present, or directly replace the clamp with the corresponding electromechanical component model. The overall operation is cumbersome, which results in the clamp being unable to quickly clamp and fix the motor parts according to their size, and the clamp has low flexibility in use, thereby reducing work efficiency.

[0021] like Figure 1 - Figure 5 As shown, a machine tool fixture for motor processing includes a machine tool body 1, on which a clamping and fixing mechanism 2 is provided, the clamping and fixing mechanism 2 includes a fixed seat 3, a bidirectional screw 8, an adjusting block 11, a movable block 13, a connecting rod 15 and a clamping plate 17, the bidirectional screw 8 is movably connected to the front end wall of the fixed seat 3 through the first rotating rods 9 at the upper and lower ends, and the two adjusting blocks 11 are movably connected to the bidirectional screw 8 through the screw holes 12 on the top surface respectively, the two movable blocks 13 are movably connected to the front end wall of the fixed seat 3 through the sliders 14 at the upper and lower ends respectively, and the movable block 13 and the adjusting block 11 are connected together through the symmetrical connecting rods 15 movable rods, and the clamping plate 17 is fixedly connected to the front end wall of the movable block 13.

[0022] like Figure 1 - Figure 5As shown, in this embodiment, in order to conveniently and quickly clamp and fix motor parts of different sizes on the machine tool body 1 for processing through the clamping and fixing mechanism 2, a vertical opening 4 is opened on the front end wall of the fixing seat 3, and the internal top surface and bottom surface of the vertical opening 4 are respectively opened with a first rotating hole 5, and the front end wall of the fixing seat 3 is also opened with a transverse opening 6 intersecting with the vertical opening 4, and the internal bottom surface and bottom surface of the transverse opening 6 are respectively opened with a group of left-right symmetrical sliding grooves 7, the upper and lower ends of the bidirectional screw 8 are respectively fixedly installed with first rotating rods 9, and the first rotating rod 9 is movably installed in the first rotating hole 5, and a knob 10 is fixedly installed on the end wall of the upper first rotating rod 9, and the knob 10 is adjusted. A screw hole 12 is provided on the top surface of the segment block 11 and is threadedly connected with the bidirectional screw rod 8 through the screw hole 12, and a group of symmetrical second rotating rods 19 are fixedly installed on the rear end wall of the adjusting block 11, and sliders 14 are fixedly installed on the upper and lower ends of the movable block 13, and the sliders 14 are movably installed in the slide groove 7, and a group of symmetrical second rotating rods 19 are also fixedly installed on the rear end wall of the movable block 13, and a clamping plate 17 is also fixedly installed on the front end wall of the movable block 13, and an arc-shaped clamping opening 18 is provided on the inner side wall of the clamping plate 17, and second rotating holes 16 are respectively provided on both sides of the front end wall of the connecting rod 15, and the second rotating rods 19 are movably installed in the second rotating holes 16;
