Description
Technical field
The present invention relates to a kind of clamping device, be specifically related to a kind of tension-type workpiece locking device.
Background technology
During Digit Control Machine Tool process equipment machining workpiece, normally use the piece-holder that active grab is to be processed on which bench.For this class workpiece of cutter of processing belt handle of a knife, usually Workpiece clamping to be felt relieved, then handle of a knife is processed.
Handle of a knife one end is cylindric, and one end is coniform, is a kind of irregular solid, and existing active grab is difficult to clamp handle of a knife and feel relieved, so process more complicated; In addition, the existing mode directly applying chucking power at surface of the work, easily by surface of the work clamping distortion, causes damage to surface of the work.
Summary of the invention
For the defect that above-mentioned prior art exists, the object of the present invention is to provide a kind of tension-type workpiece locking device that can not cause damage to surface of the work.
For achieving the above object, technical scheme of the present invention is:
Tension-type workpiece locking device, comprise clamp body, wherein, described clamp body established the circular hole of connection and coordinate the conical bore of handle of a knife workpiece, minor diameter one end of described conical bore is identical with Circularhole diameter, described clamp body be provided with along Circular Aperture to and run through the Bar lock tieholen of clamp body, have additional oblique cutting plate and fluting blind rivet, described oblique cutting plate coordinates with Bar lock tieholen, and oblique cutting plate is inclined-plane away from conical bore side, circular hole is inserted in described fluting blind rivet one end, and be slidably connected with circular hole, fluting blind rivet one end other end is provided with the external screw thread of the handle of a knife workpiece that is connected, fluting blind rivet is provided with through hole radially, this through hole side coordinates with the inclined-plane of oblique cutting plate.
When adopting technique scheme, because fluting blind rivet one end is provided with the external screw thread of the handle of a knife workpiece that is connected, first fluting blind rivet is connected with the fabrication hole that handle of a knife workpiece is offered, then fluting blind rivet is inserted in the circular hole of clamp body, through hole on fluting blind rivet and Bar lock tieholen are aligned, subsequently oblique cutting plate to be inserted in Bar lock tieholen and through hole and to press down, because the inclined-plane of through hole side with oblique cutting plate coordinates, so oblique cutting plate applies pressure on the inwall of fluting blind rivet through hole, because oblique cutting plate is inclined-plane away from conical bore side, so oblique cutting plate makes fluting blind rivet towards moving away from conical bore side, because conical bore coordinates handle of a knife workpiece, thus handle of a knife workpiece is strained.Workpiece, by pulling workpiece, is fixed by conical bore by the present invention, instead of directly applies chucking power on the surface of workpiece, so surface of the work can not be made to be out of shape, thus disfiguring workpiece is surperficial.
Further, the clamp body of described oblique cutting plate both sides is provided with and holds out against screw.Oblique cutting plate will hold out against screw-driving after inserting Bar lock tieholen and through hole, so just can prevent oblique cutting plate from loosening and fly out.
Further, described clamp body is provided with pilot hole and mounting disc near circular hole side, and mounting disc is circumferentially with at least three installing holes.So just clamp body can be arranged on lathe use by pilot hole.
Further, described oblique cutting plate upper end is provided with lifting ear.Conveniently oblique cutting plate can be taken out by lifting ear, thus unclamp workpiece.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of tension-type workpiece locking device embodiment of the present invention;
Fig. 2 is the sectional view of Fig. 1 along A-A direction.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
As shown in Figure 1, a kind of tension-type workpiece locking device, comprise clamp body 1, wherein, clamp body 1 established the circular hole of connection and coordinate the conical bore of handle of a knife workpiece 6, minor diameter one end of conical bore is identical with Circularhole diameter, clamp body 1 be provided with along Circular Aperture to and run through the Bar lock tieholen 2 of clamp body 1, have additional oblique cutting plate 3 and fluting blind rivet 4, oblique cutting plate 3 coordinates with Bar lock tieholen 2, and oblique cutting plate 3 is inclined-plane away from conical bore side, circular hole is inserted in fluting blind rivet 4 one end, and be slidably connected with circular hole, fluting blind rivet 4 one end other end is provided with the external screw thread of the handle of a knife workpiece 6 that is connected, fluting blind rivet 4 is provided with through hole radially, this through hole side coordinates with the inclined-plane of oblique cutting plate 3.
As shown in Figure 2, in the present embodiment, the clamp body 1 of oblique cutting plate 3 both sides is provided with and holds out against screw 8.After oblique cutting plate 3 inserts Bar lock tieholen 2 and through hole, screw 8 will be held out against and tighten, and so just can prevent oblique cutting plate 3 from loosening and fly out.
Clamp body 1 is provided with pilot hole 51 and mounting disc 5 near circular hole side, and mounting disc 5 is circumferentially with at least three installing holes 52.So just clamp body 1 can be arranged on lathe use by pilot hole 51.
Oblique cutting plate 3 upper end is provided with lifting ear 7.Conveniently oblique cutting plate 3 can be taken out by lifting ear 7, thus unclamp workpiece.
Specific works principle:
As shown in Figure 1, because fluting blind rivet 4 one end is provided with the external screw thread of the handle of a knife workpiece 6 that is connected, first fluting blind rivet 4 is connected with the fabrication hole that handle of a knife workpiece 6 is offered, then fluting blind rivet 4 is inserted in the circular hole of clamp body 1, through hole on fluting blind rivet 4 and Bar lock tieholen 2 are aligned, subsequently oblique cutting plate 3 to be inserted in Bar lock tieholen 2 and through hole and to press down, because the inclined-plane of through hole side with oblique cutting plate 3 coordinates, so oblique cutting plate 3 applies pressure on the inwall of fluting blind rivet 4 through hole, because oblique cutting plate 3 is inclined-plane away from conical bore side, so oblique cutting plate 3 makes fluting blind rivet 4 move towards away from conical bore side, because conical bore coordinates handle of a knife workpiece 6, thus handle of a knife workpiece 6 is strained.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
