Abstract

The utility model relates to a machinery clamp, in particular to a clamp which is used by a bench worker and is suitable for being arranged on a working table for a bench worker. The clamp is provided with a supporting bracket whose upper part is provided with a longitudinal through hole whose one side is provided with a vertical through hole, a lower locking block and an upper locking block. The lower part of the longitudinal through hole is orderly provided with a lateral leveling screw hole and a pin shaft hole which are parallel. The lower locking block is provided with a middle threaded hole, an outer cylindrical surface and an inner cylindrical surface at the right-upper corner. The upper locking block is provided with a middle through hole, an outer cylindrical surface and an inner cylindrical surface at the right-lower corner. The upper part of the two upright walls of a base is provided with a circular arc trough. The middle part of the lower part is provided with a lock shaft hole. The inner surfaces of two vice jaw sleeves are respectively matched and connected with the upper dummy clubs of the vice jaws of a static vice seat and a movable vice seat, a vertical surface and a lower horizontal surface by a demountable mode. Therefore, the utility model can be fit for different working conditions and can be clamped by different workpieces. The operation is convenient.

Description

Multi-purpose vise

The utility model relates to a kind of mechanical clamp, especially is applicable to the pincers worker anchor clamps that are installed on the fitter's bench.

At present, the quiet pincers of common bench vice seat and moving pincers seat can only be at the horizontal level clamping work pieces, and the jaw cover is the non-removable jaw that is fixed on, therefore, and inconvenient operation, nor can satisfy the needs of clamping difformity workpiece.

The purpose of this utility model is that a kind of multifunctional bench clamp will be provided, and makes the pincers seats can be around orthogonal two horizontal rotational shaft, and the jaw cover can be changed.

The purpose of this utility model is achieved in that and is provided with the vertical through hole that has longitudinal hole and longitudinal hole one side on top, below longitudinal hole, have the parallel transverse horizontal bolt hole and the bearing support of pin shaft hole successively, screw in the middle of being provided with, the following latch segment of the inner cylinder face in the external cylindrical surface and the upper right corner, be provided with intermediate throughholes, the last latch segment of the inner cylinder face in the external cylindrical surface and the lower right corner, above two perpendicular walls of base, arc groove is arranged, the below interposition is equipped with pin shaft hole, the inner face of two jaws covers respectively with quiet pincers, the convex platform of moving pincers seat jaw, vertical plane and lower horizontal plane are connected with dismountable.When pincers seats is wanted dislocation, unclamp the screw of the upper and lower latch segment of tension, quiet pincers seat (together with moving pincers seat) outside cylinder just can be rotated in the longitudinal hole of bearing support, tighten quiet pincers of screw lock during to the needs position.When pincers seats will tilt forward and back, unclamp bolt, nut in the arc groove, bearing support (together with the pincers seat) can rotate by the bearing pin in pin shaft hole, tights a bolt during to the needs angle of inclination, nut.When needs are changed difform jaw cover, overcome the power that is connected that jaw cover and jaw cooperate from any side direction of jaw, jaw overlaps and just can disassemble.

Owing to adopt such scheme, can adapt to the clamping and the processing of different operating situation, difformity workpiece, and also easy to operate.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the Facad structure schematic diagram of an embodiment of the present utility model.

Fig. 2 is the side structure schematic diagram of an embodiment of the present utility model.

Among the figure: 1. bearing support, 1a. longitudinal hole, the vertical through hole of 1b., 1c. dowel hole, 1d. bolt hole, 1e. pin shaft hole, 2. quiet pincers seat, 2a. external cylindrical surface, 2b. annular groove, 2c. jaw, 2d. inner chamber, 3. moving pincers seat, 3a. cell body, 3b. cinclides, 4. base before the jaw, 3c., 4a. perpendicular wall, 4b. arc groove, 4c. pin shaft hole, 5. descend latch segment, 5a. screw, 5b. external cylindrical surface, 5c. inner cylinder face is 6. gone up latch segment, the 6a. screw hole, 6b. external cylindrical surface, 6c. inner cylinder face, 7. little alignment pin, 8. jaw cover, 9. screw, 10. screw mandrel.

In embodiment illustrated in figures 1 and 2:

The top of bearing support 1 has longitudinal hole 1a and has vertical through hole 1b in longitudinal hole 1a one side; On the plane, top in longitudinal hole 1a stage casing, have a location pin-and-hole 1c, below longitudinal hole, have the transverse horizontal bolt hole 1d and the pin-and-hole 1e that are parallel to each other successively.

The external cylindrical surface 2a of quiet pincers seat 2 matches slidably with the longitudinal hole 1a of bearing support 1, both can relatively rotate, have an annular groove 2b in external cylindrical surface 2a stage casing, this annular groove 2b is corresponding with dowel hole 1c position, and match with little alignment pin 7, make quiet pincers seat 2 relatively bearing support 1 vertically move.Jaw 2c at quiet pincers seat 2 has convex platform, vertical plane and lower horizontal plane, and dismountable being connected adopted on the inner face of jaw cover 8 and above-mentioned jaw 2c surface, supply with the replacing (shape, material difference according to clamped workpiece decide) of different profile jaw covers 8, in addition, in the inner chamber 2d of quiet pincers seat 2, be screwed connection one screw 9.

The cell body 3a of moving pincers seat 3 is supported among the inner chamber 2d of quiet pincers seat 2, and jaw 3b is identical with the jaw 2c shape of quiet pincers seat 2, same dismountable jaw cover 8 that is connected.Cinclides 3c before on the antetheca of moving pincers seat 3, also being provided with.

Screw mandrel 10 has the screw thread that matches with screw 9, and front end exposes in preceding cinclides 3c outside, inserts at front end and revolves handle, also connects compression spring and folder spring coil on the screw mandrel 10 between preceding cinclides 3c and screw 9 front ends, is convenient to jaw 2c, 3b and throws off.

Two perpendicular wall 4a tops of base 4 have arc groove 4b corresponding with the bolt hole 1d position of supporting base 1, position with bolt, 1 inclination of nut check bearing support, the angular range of arc groove 4b changes 20 degree, and that the below interposition is equipped with pin shaft hole 4c is corresponding with the bearing pin 1e position of bearing support 1, and the bearing pin of packing into and matching, bearing support 1 can be rotated relative to base 4.

Following latch segment 5 has middle screw 5a, external cylindrical surface 5b and upper right corner inner cylinder face 5c.External cylindrical surface 5b cooperates with vertical through hole 1b hypomere, upper right corner inner cylinder face 5c and quiet 2 the cylindrical of clamping
