Description

A plunger type wedge clamping device

technical field

The utility model relates to a plunger type wedge clamping device, which belongs to the technical field of mechanical processing.

Background technique

In mechanical processing technology, the clamping requirements for the workpiece are very high. In the fitter clamping, the flat-nose pliers are usually used for clamping. For complex or irregular parts, it is time-consuming and difficult to clamp with flat-nose pliers. Firmly, if the parts are not clamped firmly, it is easy to cause the parts to fall off during the processing. If the parts fall off, it will pose a great threat to the safety of the processing equipment, and even cause injury to the operator. If the productivity of this method is low for circular parts and mass production, in order to save production costs and improve production efficiency, it is very necessary to design a plunger-type wedge clamping device.

Utility model content

In order to solve the above problems, the purpose of this utility model is to solve the above-mentioned deficiencies in the prior art, and the purpose of this utility model is to provide a plunger type wedge clamping device.

In order to solve the above problems, the utility model is realized through the following technical solutions: a plunger type wedge clamping device, which is composed of a clamp body, a round washer, a clamping nut, a positioning sleeve, a workpiece, an open washer, and a tie rod wedge , a plunger transverse wedge, a roller and a spring; it is characterized in that: the middle of the clamp body is a cross-shaped through hole; the middle and lower part of the plunger transverse wedge is an oblique wedge, and the lower part of the oblique wedge just presses on the roller. It can move in the transverse hole of the clamp body; the clamping nut is installed on the threaded shaft at the right end of the plunger transverse wedge, and a round washer is installed on the right side of the clamping nut and the clamp body; the positioning sleeve is installed on the upper end of the clamp body In the vertical hole of the positioning sleeve and is an interference fit; the tie rod wedge is installed in the hole of the positioning sleeve and the clamp body, and the hole is a clearance fit; the workpiece is installed outside the upper shaft sleeve of the positioning sleeve; the split washer Installed on the workpiece; the spring is installed in the vertical hole of the clamp body and under the roller.

The beneficial effects of the utility model are: fast, accurate and firm clamping of workpieces, simple structure, safety and reliability, easy operation and the like.

Description of drawings

Fig. 1 is a schematic structural diagram of a plunger type wedge clamping device.

Detailed ways

As shown in Figure 1, a plunger type wedge clamping device is composed of a clamp body 1, a round washer 2, a clamping nut 3, a positioning sleeve 4, a workpiece 5, a split washer 6, a rod wedge 7, a plunger Composed of a transverse wedge 8, a roller 9 and a spring 10; it is characterized in that: the middle of the clamp body 1 is a cross-shaped through hole; , which can move in the transverse hole of the clamp body 1; the clamp nut 3 is installed on the threaded shaft at the right end of the plunger transverse wedge 8, and a round washer 2 is installed on the right side of the clamp nut 3 and the clamp body 1; The positioning sleeve 4 is installed in the vertical hole on the upper end of the clamp body 1 and is an interference fit; the tie rod wedge 7 is installed in the hole of the positioning sleeve 4 and the clamp body 1, and is a clearance fit with the hole; the workpiece 5 Installed outside the upper shaft sleeve of the positioning sleeve 4; the split washer 6 is installed on the workpiece 5; the spring 10 is installed in the vertical hole of the clamp body 1 and under the roller 9. When working, rotate the clamping nut 3 in the forward direction to move the plunger transverse wedge 8 to the right, and under the action of its slope, push the roller 9 to move down, and the roller drives the rod wedge 7 to move down, and then passes through the open washer 6 The workpiece 5 is clamped. When the clamping nut 3 is reversely rotated, under the action of the spring 10, the pull bar wedge is moved up, so that the workpiece is in a relaxed state, and the workpiece can be taken off.

The utility model has been disclosed above with preferred implementations, but it is not intended to limit the utility model. All technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the utility model.
