Description

Fixed clamp

Technical field

The utility model relates to fixture field, especially relates to a kind of fixed clamp.

Background technology

Fixture is machining and fitter assembly or keeps in repair essential aid, for pressing from both sides steady workpiece, so that repair processing is carried out in pincers worker.Existing fixture is of a great variety, and the overwhelming majority adopts the locking of screw rod attaching nut, which troublesome poeration, clamp and send here, all need to spend the longer time to screw or unclamp nut, after long-time use, between nut and screw rod, wear and tear, cause clamping deleterious, service life is shorter; In addition, the fixture especially using in enterprise's production line, the workpiece of each fixture clamping is all same size, and corresponding jaws size is all the same, and the mode that adopts at present screw rod and nut to clamp causes operating efficiency lower.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of locking be provided and unclamp operation readiness, improving the fixed clamp of clamping operating efficiency.

Technical solution adopted in the utility model is: a kind of fixed clamp, comprise the first clamping plate, the second clamping plate and the 3rd latch, the first clamping plate and the second clamping plate are all L-shaped, one end of the first described clamping plate upwards extends to form the first fixture block, one end of the second clamping plate upwards extends to form the second fixture block, forms clamping oral area between the first fixture block and the second fixture block;

The lateral part body length direction of the first clamping plate is provided with a horizontal groove, and the body width of the lateral part of the first clamping plate is provided with the first groove, the first groove and laterally groove right-angled intersection;

The second clamping plate lateral part is slidably fitted in described horizontal groove, the body width of the second clamping plate lateral part is provided with the second groove, insert after the horizontal groove of the first clamping plate the lateral part of the second clamping plate, the second groove of the second clamping plate in region corresponding to the first groove of the first clamping plate, the first groove and the second groove consistent size;

The 3rd described latch is the wedge that one end diminishes gradually to the other end, and the 3rd described latch is engaged in the first groove of the first clamping plate and the second groove of the second clamping plate; The small end lateral dimension of the 3rd latch is less than the first groove lateral dimension, holds greatly lateral dimension to be greater than the first groove lateral dimension.

Described clamp port part is upper clamping oral area and lower clamping oral area, and the size of described upper clamping oral area is less than the size of lower clamping oral area.

The small end of the 3rd described latch is provided with one and prevents the limited post coming off from the first groove and the second groove.

On the first described fixture block and the second clamping plate, be equipped with the groove of person's application of force easy to use.

The beneficial effects of the utility model are: a kind of fixed clamp of the utility model, formed by the first clamping plate, the second clamping plate and the 3rd latch, on the first clamping plate and the second clamping plate, be equipped with groove, in the time that needs are locked, only the 3rd latch need to be inserted in corresponding groove, be inserted into just realization locking of the end; Only unclamp and the 3rd latch need to be unpluged, lock and unclamp very convenient quick.

Detailed description of the invention

Shown in Fig. 1-Fig. 5, a kind of fixed clamp of the utility model, comprise the first clamping plate 1, the second clamping plate 2 and the 3rd latch 3, the first clamping plate 1 and the second clamping plate 2 are all L-shaped, one end of the first described clamping plate 1 upwards extends to form the first fixture block 1.1, one end of the second clamping plate 2 upwards extends to form between the second fixture block 2.1, the first fixture blocks 1.1 and the second fixture block 2.1 and forms and clamp oral area; The body width that the lateral part body length direction of the first clamping plate 1 is provided with the lateral part of horizontal groove 1.3, the first clamping plate 1 is provided with the first groove 1.2, the first grooves 1.2 and laterally groove 1.3 right-angled intersections; The second clamping plate 2 lateral parts are slidably fitted in described horizontal groove 1.3, the body width of the second clamping plate 2 lateral parts is provided with the second groove 2.2, insert after the horizontal groove 1.3 of the first clamping plate 1 lateral part of the second clamping plate 2, the second groove 2.2 of the second clamping plate 2 in the region of the first groove 1.2 correspondences of the first clamping plate 1, the first groove 1.2 and the second groove 2.2 consistent size; The 3rd described latch 3 is the wedge that one end diminishes gradually to the other end, and the 3rd described latch 3 is engaged in the first groove 1.2 of the first clamping plate 1 and the second groove 2.2 of the second clamping plate 2; The small end lateral dimension of the 3rd latch 3 is less than the first groove 1.2 lateral dimensions, holds greatly lateral dimension to be greater than the first groove 1.2 lateral dimensions.

Described clamp port part is upper clamping oral area 4.1 and lower clamping oral area 4.2, and the size of described upper clamping oral area 4.1 is less than the size of lower clamping oral area 4.2.

The small end of the 3rd described latch 3 is provided with one and prevents the limited post 3.1 coming off from the first groove 1.2 and the second groove 2.2.

On the first described fixture block 1.1 and the second clamping plate 2, be equipped with the groove 5 of person's application of force easy to use.

Operation principle of the present utility model is: shown in Fig. 4 and Fig. 5, after the first clamping plate 1 and the second clamping plate 2 assemble, the 3rd latch 3 is inserted from the first groove 1.2 one sides, through the second groove 2.2, pass from the another side of the first groove 1.2 again, because the large end size of the 3rd latch 3 is larger than the lateral dimension of the first groove 1.2, finally given limited post by the first groove 1.2, forward little extreme direction pushes away again, the first groove 1.2 and the second groove 2.2 consistent size, so the first clamping plate 1 and the second clamping plate 2 are all limited, cannot move, complete holding action, because the size of each needed clamping oral area of holding action is all the same, only the 3rd latch 3 need to be inserted into the end of to just completes holding action, extract to realize and unclamp action, by the insertion to the 3rd latch 3 with extracted locking and the action of unclamping, design such fixture, to clamp and unclamp the required time in order to reduce exactly, increasing work efficiency.
