Abstract

The utility model relates to an internal-and-external-linkage type clamping device which comprises a clamping device, a force application device and a resetting device. The clamping device comprises an expanding block and a clamping jaw, the expanding block clamps a workpiece from the inner portion, and the clamping jaw clamps the workpiece from the outer portion; the force application device comprises a force application pulling rod, a locking nut and an elastic clamping sleeve hopper are fixed at the top end of the force application pulling rod, a compression spring is arranged between the locking nut and the elastic clamping sleeve hopper, the expanding block wraps outside the elastic clamping sleeve hopper and abuts against an external flange of the elastic clamping sleeve hopper; and the clamping jaw is hinged with a support, a driven end of the clamping jaw serves as a clamping head for clamping the workpiece, a driving end of the clamping jaw is fixed on a bracket, and the bracket is fixedly connected with the force application pulling rod. A user can pull down the force application pulling rod, the force application pulling rod further presses the compression spring through the locking nut, and the compression spring acts on the elastic clamping sleeve hopper to expel the elastic clamping sleeve hopper to move downwards. The expanding block clamps a workpiece from the inner portion, and meanwhile the bracket moves downwards to drive the clamping head at the driven end to clamp the workpiece.

Description

Inside and outside linkage type clamping device
Technical field
The utility model relates to a kind of fixture for processing, is specifically related to a kind of inside and outside linkage type clamping device.
Background technology
Anchor clamps are used for fixing processing object in the machine-building process, make it to occupy correct position, with the device of accepting construction or detecting.In a broad sense, any operation in technical process is used for installing rapidly, easily and safely the device of workpiece, all can be described as anchor clamps.For example weld jig, inspection jig, assembling jig, jig etc.Wherein jig is the most common, often abbreviates anchor clamps as.On lathe during processing work, for the surface that makes workpiece can reach the drawing regulation size, geometry and with other surperficial specification requirements such as mutual alignment precision, workpiece must be located, clamped before the processing.Some workpiece needs clamp simultaneously with the outside internally owing to the particularity of its structure, thereby needs a kind of special clamping device.
The utility model content
The purpose of this utility model is to provide a kind of inside and outside linkage type clamping device, and solving workpiece needs internally the problem that clamps simultaneously with the outside.
For achieving the above object, the technical solution of the utility model is: inside and outside linkage type clamping device, comprise clamping device, force application apparatus and resetting means, and described clamping device comprises the bloated piece of clamping work pieces internally and from the jaw of outside clamping work pieces; Described force application apparatus comprises an application of force pull bar, a lock-nut and an elastic jacket bucket have been fixed in application of force pull bar top, be provided with the compression spring between lock-nut and elastic jacket bucket, described bloated piece is wrapped in the outside of elastic jacket bucket and the outboard flanges of the elastic jacket bucket of conflicting; Described jaw is hinged on the bearing, and driven end is as the chuck of clamping work pieces, and drive end is fixed on the carriage, and described carriage is fixedlyed connected with application of force pull bar.
When adopting technique scheme, the application of force of leaving behind pull bar, application of force pull bar further compresses the compression spring by lock-nut, and the compression spring action forces the elastic jacket bucket to move down on the elastic jacket bucket.Piece is wrapped in the outside of elastic jacket bucket and the outboard flanges of the elastic jacket bucket of conflicting owing to expand, and under this effect, bloated piece is clamping work pieces internally, has realized inner clamping.Simultaneously, because the drive end of jaw is fixed on the carriage, and carriage is to fixedly connected with application of force pull bar.When leaving behind application of force pull bar, carriage also can move down, because jaw is to be hinged on the bearing, jaw will rotate around pin joint like this, thereby has driven the chuck clamping work pieces of driven end.Realized the clamping mode of inside and outside interlock, clamped simultaneously inside and outside workpiece is carried out.
Further, push bloated piece better in order to make the elastic jacket bucket, the cross section of described elastic jacket bucket is U-shaped.
Further, can be general for these anchor clamps when the workpiece of clamping different size, described bearing is provided with the adjusting bolt of regulating the jaw height.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the inside and outside linkage type clamping device embodiment of the utility model.
The specific embodiment
As shown in Figure 1, the inside and outside linkage type clamping device of the utility model comprises clamping device, force application apparatus and resetting means, and clamping device comprises the bloated piece 1 of clamping work pieces internally and from the jaw 2 of outside clamping work pieces; Force application apparatus comprises an application of force pull bar 3, a lock-nut 31 and an elastic jacket bucket 32 have been fixed in application of force pull bar 3 tops, be provided with compression spring 33 between lock-nut 31 and elastic jacket bucket 32, the piece 1 that expands is wrapped in the outside of elastic jacket bucket 32 and the outboard flanges of the elastic jacket bucket 32 of conflicting; Jaw 2 is hinged on the bearing 4, and driven end 21 is as the chuck of clamping work pieces, and drive end is fixed on the carriage 5, and carriage 5 is fixed together with application of force pull bar 3.
The application of force of leaving behind pull bar 3, application of force pull bar 3 further compress compression spring 33 by lock-nut 31, and compression spring 33 acts on the elastic jacket bucket 32, forces elastic jacket bucket 32 to move down.Piece 1 is wrapped in the outside of elastic jacket bucket 32 and the outboard flanges of the elastic jacket bucket 32 of conflicting owing to expand, and under this effect, piece 1 clamping work pieces internally that expands has been realized inner clamping.Simultaneously, because the drive end of jaw 2 is fixed on the carriage 5, and carriage 5 and application of force pull bar 3 are fixed together.When leaving behind application of force pull bar 3, carriage 5 also can move down, because jaw 2 is to be hinged on the bearing 4, jaw 2 will rotate around pin joint like this, thereby has driven the chuck clamping work pieces of driven end 21.Realized the clamping mode of inside and outside interlock, clamped simultaneously inside and outside workpiece is carried out.
Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
