[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model provides Figure 1-Figure 3 The fixture for boring processing shown in the figure includes: a mounting base 1, a movable clamp 2 and a fixed clamp 3 are arranged on the top of the mounting base 1, a mounting plate 4 is installed on the top of the mounting base 1, and the mounting plate 4 is connected to the fixed clamp 3; a moving component 5 is arranged between the movable clamp 2 and the mounting base 1, the moving component 5 includes a slide groove opened on the mounting base 1 and a moving seat 51 slidably installed inside the slide groove, a screw rod 52 is rotatably installed inside the slide groove, a motor 54 is arranged on one side of the mounting base 1, the motor 54 is used to drive the screw rod 52 to rotate, and the moving seat 51 is connected to the movable clamp 2; a guide component is arranged inside the slide groove, the guide component includes two guide rods 53 fixed inside the slide groove, the screw rod 52 is located between the two guide rods 53, and the moving seat 51 is sleeved on the two guide rods 53 and the screw rod 52.

[0027] As can be seen from the above, when in use, the workpiece is first placed between the movable clamping plate 2 and the fixed clamping plate 3, and then the motor 54 drives the screw rod 52 to rotate, so that the movable seat 51 also slides in the slide groove along with the rotation of the screw rod 52, so as to realize the movement of the movable seat 51 and the movable clamping plate 2, so that the movable clamping plate 2 is close to the fixed clamping plate 3, so as to complete the clamping and installation of the movable clamping plate 2 and the fixed clamping plate 3 on the workpiece, and then the workpiece is bored for subsequent processing of the workpiece, and the movable seat 51 is limited and guided by the guide rod 53 during the movement, which can effectively prevent the movable seat 51 from rotating along with the rotation of the screw rod 52, so that the movable seat 51 is more stable when moving, and the adjustment speed of the movable clamping plate 2 is effectively improved, so as to clamp the movable clamping plate 2 and the fixed clamping plate 3 on the workpiece.

[0028] refer to Figure 1 and Figure 4 As shown, the auxiliary clamping assembly 6 includes auxiliary clamping claws 61 installed on both sides of the movable clamping plate 2 and the fixed clamping plate 3, and threaded holes opened on the movable clamping plate 2 and the fixed clamping plate 3. An adjusting screw 63 is installed on the auxiliary clamping claw 61, and the adjusting screw 63 is screwed in the threaded hole; a limiting assembly is arranged between the auxiliary clamping claw 61 and the movable clamping plate 2 and the fixed clamping plate 3, and the limiting assembly includes a limiting slot opened on the movable clamping plate 2 and the fixed clamping plate 3 and a limiting rod 62 fixed on one side of the auxiliary clamping claw 61, and the limiting rod 62 is inserted into the limiting slot; an auxiliary protective assembly is arranged on the auxiliary clamping claw 61, and the auxiliary protective assembly includes a detachable contact pad 64 installed on the auxiliary clamping claw 61.
