As preferred technical scheme: be reserved with the screwed hole of national standard bottom described clamp body.If individual product by
In mismachining tolerance size is less than normal be not easily taken out time, then use common GB bolt by screwed hole reserved below clamp body gently
Rotate ejecting product.
Base assembly is fixing for fixture, and clamp body is the primary structure of this fixture, clamp body mainly use screw rod and
Wedge structure, when being fixed on locating surface on clamp body (A as shown in Figure 2) by the product needing welding, another part is put
Put above, recycle special box spanner turn clamp nut move downward through inclined-plane transmission pressure hold out against to each
Block, so that withstanding tight block holds out against two pieces Product jointing position, ensures the axiality of two pieces product simultaneously, then is placed by platen assembly
On clamp body, tighten clamp nut on platen assembly by the two pieces product that need to weld pushing down tightly, prevent from producing during welding
Product rotate with mixing needle direction.Unclamping fastening nut after being soldered drives compression plate to take out after compression plate by L-shaped block, recycles phase
Take out the wedge structure of clamp body with principle, so that withstanding tight block loosens, take out product after welding；
The present invention uses screw mechanism as feeding structure, and utilizes split-type structural quickly to realize holding out against and product of fixture
Dismounting.After using overall processing due to withstanding tight block of the present invention, line cutting forms maximal clearance is that 0.2mm, simultaneously circularity and two pieces produce
The axiality of product also is able to ensure, and when can effectively prevent from welding, product is mobile with mixing needle motion, has simple in construction, system
Cycle of making is short, and pressure is big, and high reliability is highly suitable for product development stage and small lot batch manufacture.
Compared with prior art, it is an advantage of the current invention that: can effectively compress product, when preventing from welding, product is with stirring
Needle movement direction rotates, thus ensures welding quality；Can effectively ensure that the axiality of welding product, it is to avoid during docking, weld seam is wrong
Seam；Can be prevented effectively from postwelding causes product to take out the situation of difficulty because metal gets into fixture gap；The most also there is structure
Simply, the manufacturing cycle is short, low cost and other advantages.Use its manufacture of fixture of air-actuated jaw and Application No. 201320383472.0
Cycle is about 1～2 months, cost unit up to ten thousand, and uses the present invention manufacturing cycle about at about 1～2 week, and cost is 1～2
Between thousand yuan.
