Background

The clamping device is also called as a clamp, and in the machining process, in order to ensure accurate positioning and stable machining of a machined workpiece, the machining clamping device is often required to clamp and position the workpiece.

In the prior art, during welding, the use of the clamp generally requires a worker to operate the clamping device by hand, and then place the workpiece in the clamping mechanism of the clamping device, and if necessary, the worker needs to take the workpiece first, put down the workpiece and then operate the clamping device, pick up the workpiece to be machined again and place the workpiece in the clamping mechanism of the clamping device, so that the operation is complex, and the machining efficiency is low.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide a machining clamping device for welding process in the machining process, easy and simple to handle, convenient fixed improve welded machining efficiency.

The utility model discloses a realize through following technical scheme:

a machining clamping device comprises a clamping mechanism, a positioning mechanism and an operating mechanism, wherein the positioning mechanism is symmetrically arranged at the tail end of the clamping mechanism, the operating mechanism is fixedly connected with the positioning mechanism, the clamping mechanism comprises two clamping arms which are symmetrically arranged and an elastic part which is symmetrically arranged at one side of each clamping arm, the positioning mechanism is a first sliding sleeve arranged at the tail end of each clamping arm, each clamping arm slides in the first sliding sleeve, the elastic part comprises a first spring and a traction line, the first spring is movably arranged between each clamping arm and the first sliding sleeve, the traction line is arranged at the tail end of each clamping arm, the operating mechanism comprises a hollow loop bar, a bottom support and a pedal, the two ends of the hollow loop bar are respectively and fixedly connected with the first sliding sleeve, the bottom support is arranged at the center of the bottom of the loop bar, the pedal is located inside the bottom support, and the loop bar is fixedly connected with the first sliding sleeve, the utility model discloses a clamping arm's structure, including collet, running-board top, slider, second sliding sleeve, traction wire, bottom support, running-board top both sides are equipped with the second sliding sleeve, running-board top both sides set up with the slider that the second sliding sleeve suited, the slider is in slide in the second sliding sleeve set up both ends respectively with fixed connection's second spring between slider top and the second sliding sleeve top in the second sliding sleeve, traction wire one end with centre gripping arm end fixed connection, the other end pass the loop bar and with slider top fixed connection.

The utility model has the advantages that:

due to the positioning effect of the positioning mechanism, the restoring force effect of an elastic component in the clamping mechanism and the braking effect of the operating mechanism, when a pedal of the operating mechanism is pedaled, the pedal overcomes the pulling force of the second spring to move downwards and drives the sliding block to pull the traction wire, the traction wire pulls the clamping arm and compresses the first spring to slide towards the direction of the first spring so as to open the clamping arm, the workpiece to be machined is placed between the two clamping arms, the pedal is released, the pedal moves upwards under the restoring force effect of the second spring, the traction wire loses the pulling force, and the clamping arm fixedly clamps the workpiece to be machined under the restoring force effect of the first spring.

Drawings

Fig. 1 is a front view of the present invention.

In the figure: 1. the novel pedal clamp comprises a first sliding sleeve, 2 clamping arms, 3 first springs, 4 sleeve rods, 5 bottom supports, 6 second sliding sleeves, 7 traction wires, 8 pedals, 9 second springs and 10 sliding blocks.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the drawing, a machining clamping device, set up including fixture, symmetry fixture terminal positioning mechanism and with positioning mechanism fixed connection's operating device, fixture includes that the centre gripping arm 2 and the symmetry that two symmetries set up the elastomeric element of centre gripping arm 2 one side, positioning mechanism is for setting up the terminal first sliding sleeve 1 of centre gripping arm 2, centre gripping arm 2 is in slide in first sliding sleeve 1, elastomeric element including the activity set up first spring 3 between centre gripping arm 2 and the first sliding sleeve 1 and both ends respectively with the terminal fixed connection's of centre gripping arm 2 pull wire 7, operating device include both ends respectively with first sliding sleeve 1 fixed connection and hollow loop bar 4, set up collet 5 of loop bar 4 bottom central authorities, both ends respectively, And the pedal 8 is positioned in the bottom support 5, the loop bar 4 is fixedly connected with the first sliding sleeve 1, the second sliding sleeves 6 are arranged on two sides of the top of the bottom support 5, the sliding blocks 10 matched with the second sliding sleeves 6 are arranged on two sides of the top of the pedal 8, the sliding blocks 10 slide in the second sliding sleeves 6, the second springs 9 are arranged in the second sliding sleeves 6, two ends of each second spring are respectively fixedly connected with the tops of the sliding blocks 10 and the tops of the second sliding sleeves 6, one end of the traction wire 7 is fixedly connected with the tail ends of the clamping arms 2, and the other end of each traction wire penetrates through the loop bar 4 and is fixedly connected with the tops of the sliding blocks. When the pedal plate 8 is stepped on, the clamping arms overcome the elasticity of the first spring to slide towards the direction of the first spring in the first sliding sleeve under the pulling action of the traction line, so that the two clamping arms are opened, the workpiece to be machined is placed between the clamping arms, the pedal plate is loosened, the clamping arms clamp the workpiece under the action of the restoring force of the first spring, and the machining efficiency of the workpiece in the welding process is improved.

During operation, an operator steps on the pedal 8 to drive the slider 10 to overcome the tension of the second spring 9 and slide downwards in the second sliding sleeve 6, the slider 10 moves downwards to pull the traction wire 7 to drive the clamping arms 2 to overcome the elasticity of the first spring 3 and slide towards the direction of the first spring 3, the clamping arms 2 are opened, the workpiece to be processed is placed between the two clamping arms 2, the pedal 8 is loosened, the slider 10 slides upwards in the second sliding sleeve 6 under the action of the restoring force of the second spring 9 to enable the pedal 8 to return to the original position, at the moment, the traction wire 7 loses the pulling force, and the clamping arms 2 slide towards the direction deviating from the first spring 3 under the action of the restoring force of the first spring 3 and clamp the workpiece to be processed between the clamping arms 2.
