Abstract

The utility model discloses a swinging-arm pneumatic fixture. Specific to different requirements on fixtures by different clamping positions of different product workpieces, the utility model provides a swinging-arm pneumatic fixture adopting compression clamping. The swinging-arm pneumatic fixture comprises a rack and a cylinder fixed on the rack, wherein the rack is further provided with a support. The swinging-arm pneumatic fixture is characterized in that the support is provided with a swinging arm; the middle part of the swinging arm is connected with the top of support in a swinging way through an adapter; one end of the swinging arm is hinged to a piston of a hydraulic cylinder; a pressure arm is arranged at the other end of the swinging arm; the pressure arm is provided with a pressure block. The swinging-arm pneumatic fixture is suitable for compression clamping of a planar rack; the clamping length of the pressure arm is large, and higher clamping stability and reliability are achieved; the swinging amplitude of the swinging arm is limited by adopting a limiting block, so that damages caused by excessive free swinging are avoided.

Description

A kind of swing arm air-actuated jaw

Technical field

The utility model relates to a kind of fixture, particularly a kind of air-actuated jaw of swing arm.

Background technology

A lot of industrial products in process of production, need to position, and then process, and need to use nipper.For different types of product, the profile of product and locating hole point all have difference, need to use fixture miscellaneous, the stability of fixture itself, and the reliability that coordinates of fixture and product workpiece, to product Accuracy of finish important, so different product workpiece and even different clip positions all have different requirements to fixture.

As the patent CN202344298U of bulletin on July 25th, 2012, mentioned a kind of hydraulically operated fixture, comprise holder, movable pressure plate and hydraulic lifting arm, on described holder, be provided with elevating lever connecting hole, the diameter of the diameter of described elevating lever connecting hole and described hydraulic lifting arm adapts, described holder is flexibly connected with described hydraulic lifting arm, described hydraulic lifting arm is fixedly connected with described movable pressure plate, described fixture also comprises gag lever post, and described gag lever post is connected with described holder.This apparatus structure has limited the top that hydraulic mechanism must be positioned at fixture, holder also must be fixed on the top of being pressed workpiece, for frame, have particular requirement, limited the scope of application of fixture, therefore above-mentioned fixture can not be adapted to all need to pressure in the piece-holder of folder.

Summary of the invention

The purpose of this utility model is fixture is had to the problem of different requirements for the different clip positions of different product workpiece, and a kind of swing arm air-actuated jaw that adopts compression clamping is provided.

The utility model solves the technical scheme that its technical problem adopts: a kind of swing arm air-actuated jaw, comprise stand, be fixed on the cylinder on stand, on stand, be also provided with bearing, described bearing is provided with swing arm, swing arm middle part is swung and is connected by adaptor with bearing top, the piston hinge of swing arm one end and cylinder, the swing arm other end is provided with pressure arm, and pressure arm is provided with briquetting.By air cylinder driven swing arm, swing, swing arm drives pressure arm to press down, and by briquetting compression clamping workpiece, cylinder and bearing can be fixed on same plane stand, and the workpiece on stand is clamped.

As preferably, described pressure arm is the strip vertical with swing arm, and pressure arm downside is fixed on the strip briquetting that pressure arm direction is consistent.Pressure arm and briquetting have longer lateral length, and in the time of compression clamping, thrust distribution length is long, and pressure is even, and clamping is stable, and workpiece is difficult for one-sided swing.

As preferably, described pressure arm and briquetting are fixed by the screw of multiple spot, are also provided with pad between pressure arm and briquetting.

As preferably, the side near pressure arm on described bearing is provided with the limited block that restriction pressure arm presses down amplitude.Bearing is provided with limited block, and when the pressure arm bottom is during to certain position, limited block can withstand swing arm and carry out spacingly, avoids the empty pendulum of pressure arm to swing and excessively causes damage.

As preferably, adaptor is I shape, adaptor one end be folded in bearing top and bearing hinged, it is hinged with swing arm that the other end is folded in swing arm middle part.Because bearing and cylinder are fixed structure, during the piston up-down of cylinder, specifically remain unchanged with bearing level, therefore must adopt the scope of activities of adaptor liberation swing arm, could normally swing, when swing arm swings, adaptor swings by a small margin with swing arm.

As preferably, described cylinder piston vertically arranges upward.

The utility model adopts the air-actuated jaw of swing arm, is suitable for the compression clamping with plane stand; Pressure arm clamping length is large, clamps more reliable and stable; Adopt limited block to define swing arm amplitude of fluctuation, avoid empty pendulum excessively to cause damage.

Accompanying drawing explanation

Fig. 2 is the utility model seat structure schematic diagram.

To be that this use is novel be installed on the structural representation on stand to Fig. 3 together with other fixtures.

In figure: 1. stand, 2. cylinder, 3. piston, 4. swing arm, 5. briquetting, 6. pressure arm, 7. pad, 8. adaptor, 9. bearing, 10. limited block.

The specific embodiment

Below by specific embodiment, also by reference to the accompanying drawings the utility model is further illustrated.

Embodiment: a kind of swing arm air-actuated jaw, as shown in Figure 1, Figure 3.This device is arranged on plane stand 1 and uses.Perforate on stand, cylinder 2 is fixed on the lower surface of stand 1, and the piston of cylinder 3 is through one end of hinged swing arm 4 straight up, the hole of step.On stand 1, be also fixed with bearing 9, the middle part of swing arm 4 swings by adaptor 8 top that is connected to bearing 9, and adaptor 8 is I shape, hinged swing arm 4 middle parts, one end, the top of the hinged stand of the other end.4 the other end of swing arm is pressure arm 6, and pressure arm 6 is the strip vertical with swing arm 4, and the downside of pressure arm 6 is fixed with the briquetting of strip, and briquetting 5 is consistent with pressure arm direction, and briquetting 5 length are greater than pressure arm length.On pressure arm, evenly offer 5 fixing holes, on briquetting, correspondence arranges screwed hole, and both adopt and are screwed, and is provided with pad 7 between pressure arm and briquetting.As shown in Figure 2, bearing is provided with limited block 10 near a side of pressure arm, limits the amplitude of fluctuation that presses down of pressure arm.

During work, thereby drive piston up-down to control swing arm by cylinder, swing up and down, further control pressure arm and press down or lift, transfer block swings by a small margin with swing arm.
