Push rod is by air cylinder driven.During use, workpiece is placed in V-block, then operate air cylinder driven push rod to move down, because the first acute ends of clamp is connected by spring with in the middle part of holder, second acute ends of clamp is then the working end for workpiece pressing, and wherein the bottom of U-shaped connecting plate is threaded fixing with push rod; In the process moved down along with push rod at U-shaped connecting plate, first acute ends of clamp swings to vertical direction from horizontal direction gradually, second acute ends of clamp then swings to horizontal direction from vertical direction, the load of spring makes the first acute ends of clamp offset to this section of right angle end and holder upright side walls, and the second acute ends is clamping work pieces downwards under push rod traction then.
After machining, control cylinder drives push rod to move up, at U-shaped connecting plate along with in the process that push rod moves, first acute ends of clamp swings to horizontal direction from vertical direction gradually, second acute ends of clamp then swings to vertical direction from horizontal direction, the load of spring makes the first acute ends of clamp offset to this section of right angle end and holder horizontal top surface, and the second acute ends then unclamps workpiece under push rod traction, can take off workpiece.
This programme structure is simple, and processing ease, is convenient to quick-clamping bar, improves bar alignment efficiency.
Further, the first acute ends of clamp is convexly equipped with connecting pin; The Fast Installation of spring is facilitated to dismantle.
Further, also comprise wear-resistant sleeve, wear-resistant sleeve, between holder and V-block, holder, V-block also has the groove for fixing wear-resistant sleeve; Facilitate the fixing of push rod, avoid holder and V-block to wear and tear simultaneously, improve the service life of this device.
Further, the swinging track along clamp on holder has also been wholely set baffle plate; Baffle plate plays the effect of guide and limit, ensures the stable operation of clamp.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: holder 10, spring 11, V-block 12, clamp 20, push rod 30, U-shaped connecting plate 31, wear-resistant sleeve 32, workpiece 40.
Embodiment is substantially as shown in Figure 1: bar work 40 processing fixture, comprises frame, also comprises in frame and is disposed with clamp 20, holder 10, spring 11, U-shaped connecting plate 31, V-block 12 and push rod 30 from top to bottom; Be connected by screw between wherein on the left of holder 10 lower end and frame and pass through finger setting; Clamp 20 is triangle at right angles, clamp 20 comprises the first acute ends, the second acute ends and right angle end, pin-hinges is passed through in right angle end and U-shaped connecting plate 31 upper end of clamp 20, first acute ends of clamp 20 is connected by described spring 11 with in the middle part of holder 10, second acute ends of clamp 20 is then the working end for workpiece pressing 40, wherein the bottom of U-shaped connecting plate 31 is threaded fixing with push rod 30, passes through finger setting between on the right side of V-block 12 and frame by bolt-connection.
Push rod 30 is by air cylinder driven.Wear-resistant sleeve 32, between holder 10 and V-block 12, holder 10, V-block 12 also has the groove for fixing wear-resistant sleeve 32.The load of spring 11 makes the first acute ends of clamp 20 offset to this section of right angle end and holder 10.First acute ends of clamp 20 is convexly equipped with connecting pin.Holder 10 has also been wholely set baffle plate along the swinging track of clamp 20.
