Push rod is by air cylinder driven.During use, workpiece is placed in V-block, then operation air cylinder driven push rod moves down, owing to the first acute ends of clamping block is connected by spring in the middle part of fixing seat, second acute ends of clamping block is then the working end for workpiece pressing, and wherein the bottom of U-shaped connecting plate is threadeded fixing with push rod;During U-shaped connecting plate moves down along with push rod, first acute ends of clamping block gradually swings to vertical direction from horizontal direction, the second acute ends clamping block then swings to horizontal direction from vertical direction, the load of spring makes the first acute ends of clamping block offset to this section of right angle end with fixing seat upright side walls, and the second acute ends then clamps downwards workpiece under push rod draws.
After machining, control air cylinder driven push rod to move up, during U-shaped connecting plate is along with moving on push rod, first acute ends of clamping block gradually swings to horizontal direction from vertical direction, the second acute ends clamping block then swings to vertical direction from horizontal direction, the load of spring makes the first acute ends of clamping block offset to this section of right angle end with fixing seat horizontal top surface, and the second acute ends then unclamps workpiece under push rod draws, and can take off workpiece.
This programme simple in construction, processing ease, it is simple to quick-clamping bar, improves bar alignment efficiency.
Further, the first acute ends of clamping block is convexly equipped with connecting pin;The Fast Installation facilitating spring is dismantled.
Further, also including wear-resistant sleeve, wear-resistant sleeve, between fixing seat and V-block, fixing seat, V-block also has the groove for fixing wear-resistant sleeve;Facilitate the fixing of push rod, avoid fixing seat to wear and tear with V-block simultaneously, improve the service life of this device.
Further, fixing seat has also been wholely set baffle plate along the swinging track clamping block;Baffle plate plays the effect of guide and limit, it is ensured that the stable operation of clamping block.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Reference in Figure of description includes: fixing seat 10, spring 11, V-block 12, clamping block 20, push rod 30, U-shaped connecting plate 31, wear-resistant sleeve 32, workpiece 40.
Embodiment is the most as shown in Figure 1: bar work 40 processing fixing device, including frame, also includes the clamping block 20 set gradually from top to bottom in frame, fixing seat 10, spring 11, U-shaped connecting plate 31, V-block 12 and push rod 30;It is connected by screw between wherein fixing on the left of seat 10 lower end and frame and passes through finger setting;The clamping rectangular triangle of block 20, clamping block 20 includes the first acute ends, the second acute ends and right angle end, the right angle end of clamping block 20 passes through pin-hinges with U-shaped connecting plate 31 upper end, first acute ends of clamping block 20 is connected by described spring 11 with in the middle part of fixing seat 10, second acute ends of clamping block 20 is then the working end for workpiece pressing 40, wherein the bottom of U-shaped connecting plate 31 is threadeded fixing with push rod 30, on the right side of V-block 12 and frame between by bolt-connection and pass through finger setting.
Push rod 30 is by air cylinder driven.Wear-resistant sleeve 32, between fixing seat 10 and V-block 12, fixing seat 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 clamping block 20 offset to this section of right angle end with fixing seat 10.First acute ends of clamping block 20 is convexly equipped with connecting pin.On fixing seat 10, the swinging track along clamping block 20 has also been wholely set baffle plate.
Being one side two finger settings between on the left of fixing seat 10 lower end and frame, the axle of two pins is close matched in clearance with holes (hole, location);One of them is straight pin, and another is rhombus pin, and hole, location centre-to-centre spacing exists tolerance (error), if two pins are all straight pins, then, two pins on fixture cannot coordinate with the holes " accurately " of workpiece 40, and dress is not entered.After one of them does diamondwise pin, location hole centre-to-centre spacing error cannot interfere coordinating of two pins and holes.Analyzing from location, restraint of liberty degree, two straight pins were location.The major axis of rhombus pin, with two pin-and-hole lines of centres, it is necessary to be vertical, the most just lose the effect of rhombus pin.
