Description

Adjustable punching positioning device

Technical Field

The utility model relates to the technical field of punching positioning devices, in particular to an adjustable punching positioning device.

Background

In the mechanical processing process, in order to ensure the processing precision, firstly, a workpiece is enabled to occupy a correct position on a machine tool, the process of determining the workpiece to occupy the correct position on the machine tool or in a clamp is called positioning of the workpiece, the workpiece is fixed after positioning, the operation of keeping the positioning position unchanged all the time in the processing process is called clamping, the process of positioning and clamping the workpiece on the machine tool or the clamp is called clamping of the workpiece, and a device for clamping the workpiece is called a machine tool clamp, which is called a clamp for short. The punching work of the shaft needs to be positioned by using a clamp so as to be conveniently and accurately machined by a machine tool. However, the existing shaft punching positioning device is complex in structure and inconvenient to use.

SUMMERY OF THE UTILITY MODEL

The utility model mainly provides an adjustable punching positioning device, and solves the problems that a shaft punching positioning device in the prior art is complex in structure and inconvenient to use.

In order to solve the technical problems, the utility model adopts the following technical scheme:

the utility model provides a positioner punches with adjustable, includes the fixed block, be provided with the mounting groove on the fixed block, can dismantle in the mounting groove and be connected with the locating piece, fixed block bottom sliding connection has the tight piece of clamp, and two the tight piece symmetry of clamp sets up, be provided with the restriction on the fixed block the spacing subassembly of the tight piece of clamp. Set up like this, can press from both sides the axle through pressing from both sides tight piece, fix through spacing subassembly, other perforating device of rethread utilize the locating piece to carry out the axle and punch, are provided with the guide slot that punches on the locating piece, change different locating pieces and can improve application range, overall structure is simple, convenient to use.

Further, the fixed block is provided with a sliding groove and a groove cover, the sliding groove is internally provided with a plurality of guide rods, the clamping block is provided with guide holes matched with the guide rods, and the clamping block slides in the sliding groove through the guide rods. By the arrangement, different clamping blocks can be replaced, and the use is convenient.

Furthermore, spacing subassembly include with the threaded rod of capping swivelling joint, press from both sides and be provided with the screw of cooperation threaded rod on the tight piece of clamp. By means of the arrangement, the clamping block can move on the guide rod to clamp by rotating the threaded rod.

Further, the outer end of the threaded rod is provided with a rotating handle. So set up, be convenient for rotate the threaded rod.

Further, an arc-shaped tightening surface is arranged on the inner side of the clamping block. So arranged, the shaft is further positioned and fixed

Further, the inner side of the clamping block is provided with an anti-skid layer. With this arrangement, the shaft can be prevented from rotating, resulting in a reduction in punching accuracy.

Has the advantages that: set up like this, can press from both sides the axle through pressing from both sides tight piece, fix through spacing subassembly, other perforating device of rethread utilize the locating piece to carry out the axle and punch, are provided with the guide slot that punches on the locating piece, change different locating pieces and can improve application range, overall structure is simple, convenient to use.
