Abstract

The utility model discloses a clamping device and aims to provide a modified clamping device. The clamping device comprises clamp arms, worm wheels, camshafts, rollers, worm boxes, a plurality of worms, a transmission shaft, a die head component, positioners, return springs, and a hand wheel. The handle wheel is mounted at the right end of the transmission shaft. The worms are installed in the middle of the transmission shaft and inside the worm boxes. The worms above the worm wheels mesh with the worm wheels. The rollers are disposed on the worm wheels which are mounted on the camshafts. The upper end of each clamp arm contacts with one roller. The lower end of each clamp arm is connected with one return spring. The die head component is arranged between the clamp arms and the positioners. The clamp arms clamp or loosen the die head component so as to quickly position the die head component and the like. The clamping device has the advantages of simple structure, low cost and durability and is mainly applicable to equipment requiring for parts clamping.

Description

A kind of clamping device

Technical field

The utility model relates to a kind of clamping device, relates in particular to a kind of clamping device that parts is carried out clamping.

Background technology

Present to needing easy disassembly and fastening parts, usually use the modes such as screw, spring, demolition, installation are cumbersome like this, and fix and not too put in place, and parts are easily walked about, and affect the normal use of machinery equipment.

The utility model content

The purpose of this utility model technical problem to be solved is that a kind of clamping device will be provided, and it can efficiently solve the fastening parts easy disassembly of needs, clamping problem firmly, has simple in structure, with low cost, robust characteristics.

For achieving the above object, the technical solution adopted in the utility model is: a kind of clamping device comprises clamp arm, worm gear, camshaft, roller, worm screw case, worm screw, power transmission shaft, die head assembly, keeper, back-moving spring, handwheel; The right-hand member of described power transmission shaft is equipped with handwheel, and the centre is equipped with several worm screws, and worm screw is arranged in the worm screw case; Described worm screw is located at the top of worm gear, and worm gear and worm engaging are equipped with roller on worm gear, and worm gear is arranged on described camshaft; The upper end of described clamp arm and roller contact, the lower end of clamp arm connects described back-moving spring; Described die head assembly is located between described clamp arm and described keeper; Described clamp arm is that use is closed in two assembly.

The utility model has adopted above-mentioned technical scheme, overcome the deficiency of background technology, a kind of clamping device is provided, and it can efficiently solve the fastening parts easy disassembly of needs, clamping problem firmly, has simple in structure, with low cost, robust characteristics.

Description of drawings

Accompanying drawing 1 is structural representation of the present utility model

In figure: clamp arm 1, worm gear 2, camshaft 3, roller 4, worm screw case 5, worm screw 6, power transmission shaft 7, die head assembly 8, keeper 9, back-moving spring 10, handwheel 11.

The specific embodiment

Below in conjunction with accompanying drawing, by the specific embodiment of the present utility model is further described, make the technical solution of the utility model and beneficial effect thereof clearer, clear and definite.

Referring to accompanying drawing 1, the utility model comprises clamp arm 1, worm gear 2, camshaft 3, roller 4, worm screw case 5, worm screw 6, power transmission shaft 7, die head assembly 8, keeper 9, back-moving spring 10, handwheel 11; The right-hand member of described power transmission shaft 7 is equipped with handwheel 11, and the centre is equipped with several worm screws 6, and worm screw 6 is arranged in worm screw case 5; Described worm screw 6 is located at the top of worm gear 2, and worm gear 2 and worm screw 6 engagements are equipped with roller 4 on worm gear 2, and worm gear 2 is arranged on described camshaft 3; The upper end of described clamp arm 1 contacts with roller 4, and the lower end of clamp arm 1 connects described back-moving spring 10; Described die head assembly 8 is located between described clamp arm 1 and described keeper 9; Described clamp arm 1 is that use is closed in two assembly.

In the time of work, by rotating handwheel 10 to the direction forward shown in figure (or oppositely), driving-belt moving cam axle 3 by power transmission shaft 7, worm screw 6, turbine 2 rotates successively, under the effect that camshaft 3 rotates, roller 4 presses down (or oppositely rising) clamp arm 1 to the direction forward in figure, under the effect of lever principle, clamp arm 1 will compress (or unclamping) to the die head assembly 8 in figure, thereby realize the quick location of die head assembly etc.

Because worm-and-wheel gear belongs to effort-saving mechanism, use operation easily, reduced operating personnel's labour intensity.

Worm-and-wheel gear has auto-lock function, after clamping puts in place, the compression point of clamp arm can be remained unchanged in the position of appointment, thereby has guaranteed the stable of mechanism, uses safe and reliable.

Adopt the form of camshaft, mechanism is elongated or shortened in the vertical as required, the quantity of clamp arm is and then change also, the needs that clamp to satisfy various members.On practice, this mechanism not only can be used in the clamping of die head assembly etc., can also be used in the clamping of other mechanisms.

Arrow represents the operative orientation of associated components.

Description by above-mentioned structure and principle; the person of ordinary skill in the field is to be understood that; the utility model is not limited to the above-mentioned specific embodiment; adopt the improvement of techniques well known and substitute on the utility model basis and all drop on protection domain of the present utility model, should be limited by each claim.
