Description
Technical field
The utility model relates to Workpiece fixing technical field, especially self-centering clamping jig.
Background technology
Now weld clamp fixture adopts synchronising hinge structure at present, and two claws slide at line slide rail, realize synchronous clamping by synchronising hinge.In order to ensure that two claws are synchronous, the requirement on machining accuracy of two synchronising hinges is very high.Fixture is when clamping in addition, and synchronising hinge relative centre axle has rotation, and along with the passing of service time, on hinge, the centre-to-centre spacing in two holes just there occurs change, causes two claw synchronization accuracies to decline, just loses the function of location.
Utility model content
Technical problem to be solved in the utility model is to provide a kind ofly locates the self-centering clamping jig stepped up.
The utility model solves the technical scheme that its technical problem adopts: self-centering clamping jig, comprise pedestal and be arranged on the left slider on pedestal, right slide block, push rod, thrust unit, the right flank of described left slider, the left surface of right slide block are provided with claw, one end of described push rod is connected with the lower surface of right slide block, the other end is provided with lower tooth bar, described left slider lower surface is provided with upper rack, be provided with gear between described upper rack, lower tooth bar, described thrust unit is connected with push rod.
Further, described claw all adopts with the connection of left slider, right slide block and is threaded.
Further, described thrust unit is cylinder.
Further, described right slide block and push rod, left slider and upper rack, connection between push rod with lower tooth bar all adopt and are threaded.
Further, described pedestal is provided with backplate, described backplate is threaded with left slider, right slide block.
The beneficial effects of the utility model are: this structure can not only ensure that workpiece is located the precision clamping and can also ensure synchronous clamping for a long time, decreases machining accuracy and assembly work amount simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model master looks;
Fig. 2 is the structural representation that the utility model left side is looked.
Shown in figure: tooth bar under 1-, 2-gear, 3-left slider, 4-claw, 5-push rod, the right slide block of 6-, 7-backplate, 8-cylinder, 9-pedestal, 10-upper rack.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure 1, the utility model self-centering clamping jig, the left slider 3, right slide block 6, push rod 5, the thrust unit that comprise pedestal 9 and be arranged on pedestal 9, the right flank of described left slider 3, the left surface of right slide block 6 are provided with claw 4, one end of described push rod 5 is connected with the lower surface of right slide block 6, the other end is provided with lower tooth bar 1, and described left slider 3 lower surface is provided with upper rack 10, be provided with gear 2 between described upper rack 10, lower tooth bar 1, thrust unit is connected with push rod 5.In said apparatus, the movement of two claws 4 is driven by mobile device, and such left slider 3 is produced and the reciprocal motion of right slide block 6 by upper rack 10, gear 2, lower tooth bar 1, realizes the effect of synchronous clamping and positioning workpieces.
Thrust unit can be cylinder 8, hydraulic cylinder etc., and preferably thrust unit is cylinder 8.This fixture is applicable to various environment like this, and runs fast.
For the ease of fixture maintenance with change, be preferred embodiment that described claw 4 all adopts with the connection of left slider 3, right slide block 6 and is threaded; Described right slide block 6 and push rod 5, left slider 3 and upper rack 10, connection between push rod 5 with lower tooth bar 1 all adopt and are threaded.Each part can direct replacement like this, is convenient to maintenance, and cost-saving.
In order to strengthen the protection to fixture, preferred embodiment, described pedestal 9 is provided with backplate 7, described backplate 7 is threaded with left slider 3, right slide block 6.Backplate 7 pairs of fixtures can form protective layer.
