Description
Technical Field
The utility model particularly relates to a low impact force presss from both sides tight frame.
Background
In the clamping process of a workpiece, an execution cylinder is generally selected as an execution mechanism, and the execution cylinder is matched with other mechanical structures to form a workpiece clamping device; the ejection or contraction rigidity of the piston of the air cylinder is high, so that the workpiece can be damaged when certain workpieces with low hardness are clamped.
SUMMERY OF THE UTILITY MODEL
To the technical problem, the utility model provides a low impact force presss from both sides tight frame.
A low impact force clamping frame comprises a base; a supporting platform and a supporting block are arranged above the base; a U-shaped frame is welded above the supporting platform; the U-shaped frame is simultaneously in pivot connection with the first clamping body and the second clamping body; an air cylinder is embedded in one end of the first clamping body, and a piston rod of the air cylinder penetrates through the second clamping body and then extends into the supporting block; a piston rod of the air cylinder is provided with a pressing block, and the pressing block is positioned between the supporting block and the second clamping body; and a spring is sleeved on the body part of the piston rod between the pressing block and the upper surface of the supporting block.
Preferably, the body of the cylinder is embedded in the first clamping body; a nut is sleeved on the part between the cylinder body and the second clamping body, and the lower surface of the nut is tightly attached to the upper surface of the second clamping body in a normal state; the piston rod moves downwards to drive the nut to press the second clamping body tightly.
Preferably, a blind hole matched with the piston rod to extend into is formed in the supporting block; when the piston rod is completely extended out, the lower end face of the piston rod does not touch the bottom face of the blind hole.
The utility model provides a low impact force presss from both sides tight frame realizes pressing from both sides tightly through the cylinder, and the cooperation is equipped with buffer spring, makes the clamp of pressing from both sides tight piece tightly more flexible, has avoided the damage to the work piece.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Example (b):
referring to fig. 1 and 2, a low impact clamping frame includes a base 1; a supporting platform 2 and a supporting block 3 are arranged above the base 1; a U-shaped frame 4 is welded above the supporting platform 2; the U-shaped frame 4 is simultaneously in pivot connection with the first clamping body 5 and the second clamping body 6; the first clamping body 5 and the second clamping body 6 are arranged in parallel; an air cylinder 7 is embedded at one end of the first clamping body 5, and a piston rod 8 of the air cylinder 7 penetrates through the second clamping body 6 and then extends into the supporting block 3; a piston rod 8 of the cylinder 7 is provided with a press block 9, and the press block 9 is positioned between the supporting block 3 and the second clamping body 6; the body part of the piston rod 8 between the pressing block 9 and the upper surface of the supporting block 3 is sleeved with a spring 10. The body of the air cylinder 7 is embedded in the first clamping body 5; a nut 11 is sleeved on a part between the cylinder 7 body and the second clamping body 6, and the lower surface of the nut 11 is tightly attached to the upper surface of the second clamping body 6 in a normal state; the piston rod 8 moves downwards to drive the nut 11 to press the second clamping body 6.
A blind hole 12 matched with the piston rod 8 to extend into is arranged in the supporting block 3; when the piston rod 8 is completely extended out, the lower end surface of the piston rod 8 does not touch the bottom surface of the blind hole 12.
The implementation principle is as follows: the body of the cylinder 7 is connected with the first clamping body 5; a piston rod 8 of the air cylinder 7 is ejected out, the second clamping body 6 is driven to rotate clockwise through a nut 11, and the piston rod is matched with the first clamping body 5 to clamp; in the ejection process of the piston rod 8, the pressing block 9 presses the spring 10 for buffering the ejection process, and the end part of the piston rod 8 moves in the blind hole 12 in the supporting block 3; after clamping, under the action of the restoring force of the spring 10, the return stroke of the air cylinder 7 is quicker, and the efficiency is indirectly improved.
Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
