Abstract

The utility model discloses a kind of clamp for machining of total return pipe, including clamp bottom board, it is located at the both ends of total return pipe on clamp bottom board and is equipped with main compressed oil cylinder on the outside of total return pipe, the top of main compressed oil cylinder is set there are three plane positioning column, lateral register fulcrum bearing there are three being set on the outside of total return pipe, it is set on clamp bottom board there are six aiding support seat and six auxiliary compressed oil cylinders, is additionally provided with two sequence valves, a pressure reducing valve and a hand rotary valve on clamp bottom board.The utility model carries out workpiece compression using lever rotary oil cylinder, and pressure is uniform, and processing is stablized, and aiding support is oil pressure locking type elastic bearing, and it is oil cylinder press that auxiliary, which compresses, and processing dimension is stablized, and the clamping workpiece time is short, high production efficiency.

Description

A kind of clamp for machining of total return pipe

Technical field

The utility model belongs to a kind of clamp for machining of total return pipe.

Background technique

Currently, pressure is uneven using manual pressing plate, the unstable aiding support of processing dimension is hand-operated screw stem type bearing, Labor intensity of workers is big, and clamping working hour is long, and production efficiency is low.

Summary of the invention

The purpose of this utility model is to overcome above deficiency, provide a kind of pressure uniformly, processing stablize, production effect The clamp for machining of the high total return pipe of rate.

The purpose of this utility model is achieved through the following technical solutions:

A kind of clamp for machining of total return pipe, including clamp bottom board are located at the both ends and position of total return pipe on clamp bottom board Main compressed oil cylinder is equipped on the outside of total return pipe, the top of main compressed oil cylinder is set there are three plane positioning column, is located at total return Set on the outside of water pipe there are three lateral register fulcrum bearing, set on clamp bottom board there are six aiding support seat and six auxiliary compress it is oily Cylinder is additionally provided with two sequence valves, a pressure reducing valve and a hand rotary valve on clamp bottom board.

Compared with the prior art, the utility model has the following advantages:

The utility model carries out workpiece compression using lever rotary oil cylinder, and pressure is uniform, and processing is stablized, and aiding support is Oil pressure locking type elastic bearing, it is oil cylinder press that auxiliary, which compresses, and processing dimension is stablized, and the clamping workpiece time is short, high production efficiency.

Detailed description of the invention:

Fig. 1 is the structural schematic diagram of the utility model；

Figure label: the main compressed oil cylinder of 1- clamp bottom board, 2-, 3- plane positioning column, 4- lateral register fulcrum bearing, 5- auxiliary Fulcrum bearing, 6- assist compressed oil cylinder, 7- sequence valve, 8- pressure reducing valve, 9- hand rotary valve.

Specific embodiment:

It, below will be to the utility model to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer Technical solution in embodiment is clearly and completely described, it is clear that described embodiment is that the utility model a part is real Example is applied, instead of all the embodiments.The elements and features described in a kind of embodiment of the utility model can be with one Elements and features shown in a or more other embodiment combine.It should be noted that for purposes of clarity, in explanation The expression and description of component unrelated with the utility model, known to persons of ordinary skill in the art and processing is omitted.It is based on The embodiments of the present invention, those of ordinary skill in the art institute obtained under the premise of not making the creative labor There are other embodiments, fall within the protection scope of the utility model.

As shown in Figure 1, a kind of clamp for machining of total return pipe, including clamp bottom board 1, it is located at total return water on clamp bottom board 1 The both ends of pipe and main compressed oil cylinder 2 is equipped on the outside of total return pipe, it is fixed that the top of main compressed oil cylinder 2 sets that there are three planes Position column 3, sets on the outside of total return pipe there are three lateral register fulcrum bearing 4, sets that there are six aiding support seats on clamp bottom board 1 5 and six auxiliary compressed oil cylinders 6, two sequence valves, 7, pressure reducing valves 8 and a hand rotary valve 9 are additionally provided on clamp bottom board 1. Hand rotary valve is the switch of sequence valve, and sequence valve can be used to adjust the pressure of system with the job order of autocontrol valve, pressure reducing valve Power.

Position workpiece by three plane positioning columns and three lateral register fulcrum bearings, main compressed oil cylinder workpiece pressing, Six aiding support seat supports workpiece, six auxiliary compressed oil cylinders are compacted workpiece.

Finally, it should be noted that although the utility model and its advantage have been described in detail above it should be appreciated that Various change can be carried out without departing from the spirit and scope of the utility model being defined by the claims appended hereto Become, substitute and converts.Moreover, the scope of the utility model is not limited only to process, equipment described in specification, means, method With the specific embodiment of step.One of ordinary skilled in the art is from the disclosure of the utility model it will be readily understood that root It can be used according to the utility model and execute the function essentially identical to corresponding embodiment described herein or obtain basic with it Identical result, existing and to be developed in the future process, equipment, means, method or step.Therefore, appended right It is required that be intended to includes such process, equipment, means, method or step in the range of them.
