Description

Processing tool clamp

Technical Field

The utility model relates to an anchor clamps, concretely relates to processing frock clamp belongs to valve processing technology field.

Background

The valve is usually a workpiece with a three-way structure, and the common processing of the valve can finish the processing of three different surfaces by repeatedly clamping. In the process of repeatedly clamping the valve, machining precision errors are often caused by repeated clamping; in the process of repeatedly clamping the workpiece, the clamping is time-consuming and labor-consuming, the production efficiency is reduced, and the production cost is increased, so that certain negative effects are brought to production management. At present, a common lathe on the market mainly depends on repeated clamping for processing common valves for production and processing, the production efficiency is low, the labor intensity is high, a process clamping fixture is urgently needed to relieve the labor intensity and improve the production efficiency.

Disclosure of Invention

The utility model discloses just to the problem that exists among the prior art, provide a processing frock clamp, this technical scheme can be once the lathe work of clamping work piece three and above different faces can be accomplished.

In order to achieve the purpose, the technical scheme of the utility model is as follows, a processing tool clamp is characterized in that the clamp comprises a locking device, a left rotating shaft, a left tightening block, a right rotating shaft, an angle limiting block and a base; the locking device is fixed on the clamp base, and the left rotating shaft is fixedly arranged on the locking device; the left clamping block is fixedly arranged on the left rotating shaft and can rotate around the rotating shaft; the angle limiting block is fixedly arranged on the base; the right rotating shaft is arranged on the angle limiting block and is concentric with the left rotating shaft, and the right clamping block is arranged on the right rotating shaft. According to the scheme, clamping correction of the workpiece is reduced, and the machining precision of the workpiece is greatly improved, so that the machining efficiency of a product machine is improved, the working time is greatly saved, and the cost is reduced; because of adopting anchor clamps once to install the work piece and accomplishing the processing to the work piece, the numerous processing of the three terminal surfaces of same product can be repeated after once proofreading, practiced thrift the clamping of work piece and the correction of turning before greatly, this frock has the repeated popularization and use to greatly improved the quality and the efficiency of product processing, can be used for the refitting application of the common lathe of any brand in the market, with low costs moreover, efficient, the quality is guaranteed.

As an improvement of the utility model, the frock clamp base is connected fixedly with the lathe chuck.

As an improvement of the utility model, locking device sets up on the base, and locking device is inside to be equipped with fastener, is convenient for load and unload the work piece.

As an improvement of the utility model, the clamping device is installed between the locking devices and can rotate around the locking devices. The turntable is set to rotate 45 degrees at a time so as to facilitate the processing of different surfaces of the product. The left rotating shaft and the right rotating shaft are respectively arranged on the locking device and the angle limiting block, and the left tightening block and the right tightening block are respectively arranged on the left rotating shaft and the right rotating shaft and can rotate around the left rotating shaft and the right rotating shaft.

Compared with the prior art, the utility model has the advantages that 1) the technical proposal reduces the repeated labor caused by repeated disassembly and assembly of the workpiece in the processing process, and greatly improves the production efficiency; 2) the scheme reduces repeated clamping of the workpiece, and improves the machining precision of the workpiece to a certain extent, thereby improving the product percent of pass; because the fixture is adopted to install the workpiece once to complete the processing of the workpiece, the processing size of the product has repeated reproducibility, thereby indirectly improving the rear-end assembly efficiency and the product quality.
