Chinese patent publication number CN201632805U, November 17 2010 Granted publication day, a kind of pneumatic weld jig is disclosed, be fixed with the triangle bearing in the platform upper surface, position, triangle bearing one side upper end is fixed with the location support plate, its position, upper end has groove, fixedly there is briquetting at position, support plate upper end, location, the briquetting lower end part is by the fixedly connected upper limit position block of screw, lower position block is equipped with at position, support plate upper end, location, this utility model can each is to be welded the quick location and fixing of spare part, when avoiding welding between each spare part to be welded relative displacement takes place, make the welding position more accurate, weak point is: the clamp structure complexity is not suitable for for bigger assembly or the structure clamping and positioning of complicated parts.
Summary of the invention
The purpose of this utility model is to solve the deficiency of the anchor clamps of prior art, and a kind of pneumatic pinch structure of anchor clamps is provided, and this pneumatic pinch structure is integrated in two clamp arms in the structure, has simplified anchor clamps, and the smaller volume of anchor clamps is convenient to install and operation.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of pneumatic pinch structure of anchor clamps, comprise pedestal and the cylinder that vertically fixedly installs, vertically be fixed with air cylinder connecting rod on the piston rod of cylinder, the top of pedestal is fixed with mount pad, the both sides of mount pad are fixed with left branching rod and right pole respectively, be rotatably connected to left clamp arm on the described left branching rod, be rotatably connected to right clamp arm on the described right pole, the tail end of left and right clamp arm all is rotationally connected with air cylinder connecting rod.The utility model drives two clamp arms by stretching out of a cylinder and moves simultaneously, and the peripheral part of oriented work plate locating hole to be welded is fixedly clamped; The cylinder indentation drives two clamp arms and leaves work plate to be welded simultaneously, removes to clamp.
As preferably, mount pad is made of side plate and base plate, and the cross section of mount pad is L-shaped, and left branching rod is connected with the side plate bolt, and right pole is connected with bed bolt.The peripheral part of work plate locating hole to be welded not exclusively is level also, so need left and right clamp arm to have certain alternate position spike, thereby the clamping force of guaranteeing left and right clamp arm is even, the utility model is L-shaped by mount pad being designed to cross section, there is the alternate position spike on the vertical direction in the position of left and right pole, realizes the alternate position spike of left and right clamp arm.
As preferably, the tail end of left and right clamp arm is equipped with through hole, and left and right clamp arm was rotationally connected by cooperating with air cylinder connecting rod of through hole and rotating shaft.Left and right clamp arm was rotationally connected by through hole and cooperating with air cylinder connecting rod of rotating shaft, and left and right clamp arm rotates flexibly, the long service life of pneumatic pinch structure.
As preferably, pedestal is inverted T-shaped, and cylinder is connected with foundation bolt, and base bottom is provided with for the fixing hole that the pneumatic pinch structure is fixed on the anchor clamps, and pedestal is connected with the anchor clamps bolt.Pedestal is connected with the anchor clamps bolt, dismantles when making things convenient for the pneumatic pinch structural maintenance.
As preferably, pedestal is provided with stiffener, stiffener and pedestal welding.Stiffener is set, improves the intensity of pedestal.
As preferably, described cylinder is single-acting cylinder.Single-acting cylinder is simple in structure, and is easy to use, and cost is low.
The beneficial effects of the utility model are: the pneumatic pinch structure obtains simplifying, the smaller volume of anchor clamps, and fitting operation is simple, can not hinder the weld pass during location of complicated parts for bigger assembly or structure; Can satisfy the clamping and positioning to multi-form work plate to be welded, the active force of left and right clamp arm is even, the good reliability of clamping.
Description of drawings
Fig. 1 is structural representation of the present utility model.
