Abstract

The utility model relates to a clamping device, in particular to a thrust clamping device which comprises a base, a cam and a transmission arm, wherein the cam and the transmission arm are respectively hinged on the base. A handle is fixedly arranged on the cam. One side of the transmission arm is matched with the outer edge of the cam, and a squeezing head used for squeezing and clamping a workpiece is arranged on the end portion of the other side of the transmission arm. According to the technical scheme, the thrust clamping device is simple in structure, convenient to operate, and low in cost.

Description

The thrust clamping device

Technical field

The utility model relates to a kind of clamping device, is specifically related to a kind of thrust clamping device.

Background technology

Generally when machining, workpiece to be processed all will be fixed, and clamping device plays crucial effects when machining.

Though present clamping device miscellaneous can satisfy the requirement that workpiece clamps to a certain extent, but these clamping devices are all made under specific steric requirements, not necessarily be fit to the use with other people, be in particular in: 1, a lot of clamping device complex structures, not easy to operate, to operator's requirement height; 2, it is also higher to install complicated cost.

The utility model content

The technical problems to be solved in the utility model provides a kind of clamping device simple in structure, easy to operate, lower-cost.

In order to solve the problems of the technologies described above, the utility model provides a kind of thrust clamping device, include pedestal, be hinged on cam and transmission arm on the pedestal respectively, wherein, be set with handle on the cam, one side of transmission arm cooperates with the cam outer rim, and end side arranges the extrusion head of crushing clamp clamping of workpieces.

Use the thrust clamping device, in the time of only need pulling handle, handle drives cam rotation extruding transmission arm, and the extrusion head extruding workpiece on the transmission arm can be realized clamping, and oppositely pulls handle and can realize unclamping of workpiece.

Adopt the thrust clamping device of technique scheme to have following advantage: 1, because device mainly includes pedestal, is hinged on cam and transmission arm on the pedestal respectively, wherein, be set with handle on the cam, one side of transmission arm cooperates with the cam outer rim, and end side arranges the extrusion head of crushing clamp clamping of workpieces, constructs fairly simple, operation is only to need turning handle to get final product, and is easy to operate; 2, owing to simple structure, so the processing and manufacturing cost is lower.

As preferred version, consider that long-term use of extrusion head is easy to generate wearing and tearing, described extrusion head is by being bolted on the transmission arm, in case wearing and tearing can be passed through dismounting and change.

As preferred version, consider the long-term and cam CONTACT WITH FRICTION of transmission arm, damage bigger, therefore described transmission arm is provided with one by the friction head of bolting, this friction head and the sliding-contact of cam outer rim, cam only destroys friction head and can not destroy cam like this, uses more durable.

Description of drawings

Fig. 1 is the utility model embodiment thrust clamping device structural representation;

The specific embodiment

Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:

As shown in Figure 1, the utility model provides a kind of thrust clamping device, include pedestal 1, be hinged on cam 2 and transmission arm 3 on the pedestal respectively, wherein, be set with handle 4 on the cam 2, one side of transmission arm 3 is provided with friction head 5, friction head 5 is by being bolted to transmission arm 3 middle parts, friction head 5 and cam 2 outer rim sliding-contacts, the end of the opposite side of transmission arm 3 arranges the extrusion head 7 of crushing clamp clamping of workpieces 6, extrusion head 7 is by being bolted on the transmission arm, and friction head 5 and extrusion head 7 wearing and tearing in a single day can be dismantled and be changed.

The concrete using method of thrust clamping device is: pull handle 4, handle 4 drives the friction head 5 on the cam 2 rotation extruding

transmission arms

3, and 3 drive extrusion heads, 7 extruding workpiece 6 are realized clamping on the transmission arm, oppositely pull handle 4 and can realize unclamping of workpiece 6.

Above-described only is preferred embodiment of the present utility model, should be pointed out that for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement, these can not influence effect and practical applicability that the utility model is implemented.

Claims
