Abstract

A section bar clamp relates to a clamp for stretching section bars. The clamp includes two clamping plates obliquely installed on a clamp port, two clamping plates are provided with dovetail seats, and dovetail sliding blocks are sheathed on the dovetail sliding seats. The head of the clamp is provided with a pull rod at the rear end, a pushing arm at the front end of the pull rod is articulated with the two dovetail sliding blocks through a front connecting rod, the rear end of the pull rod is articulated with a handle, and the lower end of the handle is articulated with the body of the clamp. In use, the upper end of the handle is rotated towards the direction of the head of the clamp, the two dovetail sliding blocks slide towards the front and the middle through the pull rod and the pushing arm to tightly clamp the section bar between the two sliding blocks, and when loosening, the upper end of the handle is rotated towards the direction of the tail end of the clamp, then the two dovetail sliding blocks slide upwards, and finally the clamp loosens. The clamp has simple structure as well as simple and convenient operation, and can force the head of the clamp to achieve tight clamping effect without need of adding extra power.

Description

The section bar clamp

Technical field

The utility model belongs to a kind of section bar processing equipment technical field, the anchor clamps that use in particularly a kind of section bar that stretches.

Background technology

The anchor clamps front end that uses in the stretching technology of existing section bar has two chucks up and down, and there is pull bar the rear end, and exerting pressure by cylinder forces two chucks inwardly to clamp section bar, uses the pull bar of rear end that section bar is stretching then.This anchor clamps expend electric power owing to need compress chuck with gases at high pressure in the pressure process, and the sealing requirements height of gas, and are careless slightly, will cause gas to leak, pressure loss, and chuck is malfunctioning, stretching work failure.

The utility model content

For solving problems of the prior art, the utility model provides a kind of section bar clamp, and its embodiment is as follows:

The section bar clamp, comprise binding clip and the vice body that is connected with binding clip, binding clip comprises Jia Kou and folder chamber, the folder mouth is horn-like, by up and down two be the clamping plate that tilt to install and constitute, respectively be processed with a dovetail mount on two clamping plate, be set with the dovetail slide block of band dovetail groove on the dovetail mount, the dovetail slider bottom is a level folder face; The binding clip rear end is horizontally installed with pull bar, and pull bar is positioned on the termination in folder chamber push arm is installed, and the push arm upper and lower side is hinged by front rod and two dovetail slide blocks respectively, and it is hinged by back link and handle that pull bar is positioned at the termination of vice body, and handle, at its lower end and vice body are hinged.

During use, section bar is inserted the clamp mouth part of clamp binding clip, holding the handle upper end advances to the binding clip direction, the pull bar that handle drives and handle is hinged moves to the binding clip direction, driving push arm advances to folder mouthful direction, promoting two dovetail slide blocks by front rod slides forward on dovetail mount, because being, dovetail mount tilts to install, the dovetail slide block also moves when moving ahead in opposite directions, constantly draw close to the centre, the section bar that will be positioned at last between the two clamps, and at this moment the draw-gear that is connected on the clamp drawing head by the clamp tail end spurs clamp, just can carry out stretch process to section bar.After stretching work is finished, the handle upper end is promoted to clamp tail end direction, two dovetail slide blocks upwards slide, and clamp unclamps.

This clamp relies on mechanical force to carry out clamping, and is simple in structure, easy and simple to handle, low cost of manufacture.

As preferred version of the present utility model, binding clip and vice body can be movably connected, thereby binding clip is rotated with respect to vice body, to satisfy the needs of various working conditions; The pawl that points to the folder chamber is arranged on the folder face of dovetail slider bottom, and this design can make binding clip clamp section bar better when stretching, and avoids section bar landing from the binding clip.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Fig. 1 is a main cutaway view of the present utility model;

Fig. 2 is that A-A shown in Figure 1 is to cutaway view.

The specific embodiment

Section bar clamp as depicted in figs. 1 and 2, constitute by the binding clip 8 and the vice body 11 that flexibly connect, binding clip 8 comprises folder mouth 5 and folder chamber 9, folder mouth 5 is horn-like, by up and down two be the clamping plate 1 that tilt to install and constitute, respectively be processed with a dovetail mount 2 on two clamping plate 1, be set with the dovetail slide block 4 of band dovetail groove 3 on the dovetail mount 2, dovetail slide block 4 bottoms are level folder face 14, and the pawl that points to folder chamber 9 is arranged on the folder face 14 of dovetail slide block 1 bottom; Binding clip 8 rear ends are horizontally installed with pull bar 10, pull bar 10 is positioned on the termination that presss from both sides chamber 9 push arm 7 is installed, push arm 7 upper and lower sides are hinged by front rod 6 and two dovetail slide blocks 1 respectively, the termination that pull bar 10 is positioned at vice body 11 is hinged by back link 13 and handle 12, handle 12 lower ends and vice body 11 are hinged, and the rear portion of vice body 11 is equipped with clamp drawing head 15.
