Abstract
The invention discloses a clamping device with clamping blocks. The clamping device comprises a base, a workbench and a positioning device, wherein the workbench is used for placing workpieces and is mounted on the base. The clamping device further comprises tension springs and a cam, wherein the cam is rotationally connected with the base. The positioning device comprises two oppositely arranged clamping jaws, the middle parts of the two clamping jaws are hinged to the base, supporting rods are arranged on the inner sides of control sections of the two clamping jaws and can be propped against the cam, one end of each tension spring is connected with the control section of each clamping jaw, the other end of each tension spring is connected with the base, and secondary rods are arranged on clamping sections of the clamping jaws, are perpendicular to the clamping sections and are connected with the clamping blocks in a sliding manner. The clamping device with the clamping blocks can be used for clamping a workpiece with a slot, wherein the clamping sections of the clamping jaws can be clung to the inner wall of a lower part of the slot and then push the clamping blocks in the slot, so that the slot is clamped by the clamping blocks. The clamping jaws can not only clamp a convex surface of the workpiece, but also a concave surface; the clamping device can clamp the workpiece by utilizing not only the clamping jaws but also the clamping blocks so as to have a good clamping effect.
Description
Technical field
The invention belongs to the technical field of piece-holder.
Background technology
Workpiece, before processing, needs to be located with clamping device, prevents be moved the man-hour that adds of workpiece.The structure of existing clamping device is as follows, and comprise base, workbench, fixing pole on the table and pressing plate, the middle part of pressing plate is hinged on support plate, carrys out holding workpiece by the rotation of pressing plate.
There is a problem in above-mentioned clamping device structure, pressing plate can only protrude surface to workpiece and clamp, but sometimes we need the surface to workpiece protrudes to process.Still wish to design a kind of clamping device, ensure clamping stability time, also can as much as possible by workpiece protrude surface expose.
Summary of the invention
The invention provides a kind of clamping device with fixture block, is the problem of outer surface of workpiece with what solve that existing clamping device all clamps.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: a kind of clamping device with fixture block, comprise base, for workbench and the positioner of place work piece, workbench is arranged on base, the cam also comprising extension spring and be rotatably connected on base, described positioner comprises two jaws be oppositely arranged, the middle part of two jaws is hinged on base, the inner side of the control section of two jaws is equipped with pole, two poles all can offset with cam, one end of extension spring is connected in the control section of jaw, the other end of extension spring is connected on base, the gripping section of two jaws is provided with perpendicular secondary bar, secondary bar slidably connects fixture block.
In this article, the gripping section of jaw refers to the pin joint of jaw for boundary, near that section of workpiece; Control section refers to the pin joint of jaw for boundary, away from that section of workpiece.
Principle of the present invention is: be applicable to the workpiece that workpiece is provided with groove, and inside two jaw control sections, pole all can offset with cam.Rotating cam, the control lever meeting opening and closing of two jaws, thus control the opening and closing of jaw gripping section.The position that gripping section and the workpiece of jaw are provided with groove is corresponding, and the inwall of groove can clamp by the gripping section of jaw, also can slide by fixture block simultaneously, makes fixture block slip in groove, by fixture block, cell body is spacing.
Compared with prior art, the invention has the advantages that: can be used for clamping the workpiece with groove, the gripping section of jaw can be close to the inwall of groove lower, then pushes in groove by fixture block, and groove is clamped by fixture block.Jaw of the present invention can not only the surface of protrusion of holding workpiece, and also can clamp recessed surface, not by means of only jaw clamping, also by fixture block clamping, the effect of clamping is better.
Further, described pole is Collapsible structure, can conveniently control the opening and closing degree of jaw.
Further, described pole comprises the first screw rod, the second screw rod and sleeve, and sleeve connection is between the first screw rod and the second screw rod.The length of pole is regulated by rotational sleeve.
Further, base is provided with several installing hole, and two jaws are hinged on base by installing hole.By choosing different installing holes, regulate the distance between two jaws.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
Fig. 1 is the structural representation of the present invention with the clamp embodiment of fixture block.
Detailed description of the invention
Reference numeral in Figure of description comprises: base 1, workbench 2, extension spring 3, cam 4, jaw 5, pole 6, secondary bar 7, fixture block 8, sleeve 9.
As shown in Figure 1, a kind of clamping device with fixture block 8 in the present embodiment, comprises base 1, workbench 2 for place work piece, positioner, extension spring 3 and is rotatably connected on the diametrically symmetrical cam 4 on base 1.Workbench 2 is arranged on base 1.The middle part that described positioner comprises two jaw be oppositely arranged 5, two jaws 5 is hinged on base 1, and base 1 is provided with four installing holes, and two jaws 5 are hinged on base 1 by installing hole.The inner side of the control section of two jaws 5 is equipped with pole 6, two pole 6 all to offset with cam 4.Pole 6 comprises the first screw rod, the second screw rod and sleeve 9, and sleeve 9 is connected between the first screw rod and the second screw rod.One end of extension spring 3 is connected in the control section of jaw 5, and the other end of extension spring 3 is connected on base 1.The gripping section of two jaws 5 is provided with perpendicular secondary bar 7, and secondary bar 7 slidably connects fixture block 8.
This structure be applicable to recessed structures workpiece and there is no the workpiece of recessed structures.
When clamp be workpiece with recessed structures time, to be with reeded workpiece, rotating cam 4, the larger wire diameter place of cam 4 and two poles 6 are offseted, and the control section of two jaws 5 can be opened.Middle part because of jaw 5 is hinged on base 1, and the gripping section of two jaws 5 can be in clamped condition, and the lower inwall of groove can push against by the gripping section of jaw 5, prevents workpiece from moving left and right.At this moment, then advance fixture block 8 near the direction of groove, the shape of fixture block 8 and the form fit of groove, prevent workpiece from moving up and down.
Clamp there is no a workpiece of recessed structures time, using method is the same, just eliminates the step advanced by fixture block 8, just by jaw 5 by Workpiece clamping, because it does not have groove, therefore fixture block 8 is released seem and have little significance.Can find out, adopt this structural clamp there is no the effect of the workpiece of recessed structures not as clamping is with the workpiece of recessed structures.
Pole 6 comprises the first screw rod, the second screw rod and sleeve 9, and sleeve 9 is connected between the first screw rod and the second screw rod.Regulate the length of pole 6 by rotational sleeve 9, when rotating forward sleeve 9, the first screw rod and the second screw rod can screw out, and the length of pole 6 can increase; When rotating backward sleeve 9, the first screw rod and the second screw rod meeting precession, the length of pole 6 can shorten.Base 1 is provided with several installing hole, and two jaws 5 are hinged on base 1 by installing hole.By choosing different installing holes, regulate the distance between two jaws 5.
For a person skilled in the art, under the prerequisite not departing from structure of the present invention, can also make some distortion and improvement, 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.
