Description
Technical field
The utility model relates to material field of fixation devices, in particular to a kind of fixture.
Background technique
Fixture is to be used to fix workpiece in production process, is allowed to occupy the device of correct position.Fixture is widely used in
All conglomeraties such as timber processing, metal plate, building, decoration.For example, it is desired to pass through bonding when two workpiece are bonded together
After two workpiece contrapositions are pasted in agent, using fixture by two Workpiece clampings, occur loosening or misplace to prevent workpiece, until viscous
Tie agent solidification.
Only a pair of of clamping jaw, this fixture can only clamp a work of workpiece when clamping workpiece to existing fixture mostly
Position, when needing the biggish workpiece of clamping length, the case where being easy to appear workpiece unbalance stress, clamped workpiece is easy mistake
Position, and in order to keep workpiece stress more balanced, then it needs that Workpiece clamping is operated relatively complicated, reduction work effect using two fixtures
Rate.
Summary of the invention
The problem to be solved by the utility model is to provide a kind of fixture, this clamp structure is simple, can press from both sides securely
It holds workpiece and makes workpiece stress equalization.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is as follows:
A kind of fixture, including support rail, the first clamping limb and the second clamping limb, support rail are arranged in left-right direction,
First clamping limb and the second clamping limb or so are mounted side by side on support rail, it is characterized in that: installing on first clamping limb
There are two the first clamping jaws side by side up and down, two the second clamping jaws side by side up and down are installed on second clamping limb, two first
Clamping jaw and two second clamping jaws correspond.
When work, workpiece is placed between the first clamping limb and the second clamping limb, by adjusting two on the first clamping limb
Two the second clamping jaws on a first clamping jaw and the second clamping limb correspond, and make its mutual cooperation, corresponding first clamping jaw and
Second clamping jaw clamps two positions of workpiece, so that the stress equalization of workpiece, clamping is stronger, and clamped workpiece is not easy to send out
The case where raw dislocation.
As a preferred embodiment of the present invention, first clamping limb is equipped with two the first screw holes side by side up and down,
Two first clamping jaws and two first screw holes correspond, and the first clamping jaw includes the first screw rod, first handle and the first fixture block, the first spiral shell
Bar is in corresponding first screw hole and is threadedly coupled with the first screw hole, and the first fixture block is set to the first screw rod right end, and first handle is set
In the first screw rod left end；Second clamping limb is equipped with two the second screw holes side by side up and down, two second clamping jaws and two second
Screw hole corresponds, and the second clamping jaw includes the second screw rod, second handle and the second fixture block, and the second screw rod is in corresponding second spiral shell
