Detailed Description
The invention will be further described with reference to the accompanying drawings, without limiting the scope of the invention to the following:
as shown in FIGS. 2 to 4, a clamping device capable of clamping workpieces with different outer shapes comprises a base plate 1, a left clamping mechanism 2 and a right clamping mechanism 3 which are arranged on the base plate 1, the left clamping mechanism 2 and the right clamping mechanism 3 are symmetrically arranged in the left and right directions, the left clamping mechanism 2 comprises a clamping oil cylinder 4 and a movable block 5, the clamping oil cylinder 4 is horizontally arranged, the movable block 5 is welded on the action end of a piston rod of the clamping oil cylinder 4, a plurality of square grooves 6 are arranged on the right end surface of the movable block 5, the distances between two adjacent square grooves 6 are equal, the square grooves 6 are sequentially arranged from front to back, a movable rod 7 matched with the square grooves 6 is slidably arranged in each square groove 6, the left end and the right end of each movable rod 7 are arranged by penetrating through the square grooves 6, a limiting plate 13 is welded on the left end of each movable rod 7, a support 8 is welded on the right end of each movable rod 7, a pressing strip, the movable rod 7 is sleeved with a spring 10, one section of the spring 10 is welded on the bracket 8, the other end of the spring 10 is welded on the right end face of the movable block 5,
left side fixture 2 still includes two guide rails 11, and two equal level settings of guide rail 11 just all set firmly on bottom plate 1. Two sliding grooves 12 are formed in the bottom of the movable block 5, and the two sliding grooves 12 of the movable block 5 are respectively slidably mounted on the two guide rails 11.
The working process of the utility model is as follows:
a worker places the workpiece with the arc surface on the top surface of the bottom plate 1 and ensures that the workpiece with the arc surface is positioned between the pressing strip 9 of the left clamping mechanism 2 and the pressing strip 9 of the right clamping mechanism 3, then the worker operates the piston rods of the clamping oil cylinder 4 of the left clamping mechanism 2 and the clamping oil cylinder 4 of the right clamping mechanism 3 to extend out, the piston rods drive the two movable blocks 5 to move relatively, when in movement, the end face of the pressing strip 9 is pressed on the arc-shaped face of the workpiece in a self-adaptive manner and is tangent to the contact point of the arc-shaped face, the pressing strip 9 is provided with the support 8 to move towards the direction of the square groove 6 after being subjected to reverse force, the support 8 drives the movable rod 7 to retract into the square groove 6 and compress the spring 10, when the movable block 5 moves to a certain distance, the manual detection is carried out to determine whether the workpiece can still move, if the worker can not move the workpiece, the clamping oil cylinder 4 is closed by the worker, and the workpiece with the arc surface is clamped between the pressing strips 9 of the left clamping mechanism 2 and the pressing strips 9 of the right clamping mechanism 3; if the worker can also displace the workpiece, the piston rod continues to extend until the workpiece can no longer move.
