Abstract
The invention relates to a fixing clamp, and particularly relates to a composite clamping device of double cams. The composite clamping device comprises a clamp base body, a spring jacket, a jacket pin, a pressure plate, a jacket pin cam, a pressure plate cam and a cam hand shank, wherein the spring jacket extrudes an inner hole of a work-piece; the upper end of the jacket pin is clamped inside the spring jacket; the pressure plate extrudes the lateral wall of the work-piece; the jacket pin cam, the pressure plate cam and the cam hand shank are coaxially fixed; a nut which resists against the jacket pin cam is fixed at the lower part of the jacket pin; a spring for keeping the spring jacket expanding is arranged between the nut and the spring jacket; a clamp base body is hinged with the middle part of the pressure plate; and a drive end of the pressure plate resists against the pressure plate cam, and a driven end of the pressure plate resists against the lateral wall of the work-piece. The composite clamping device has the beneficial effects that the clamping device is artfully and reasonably arranged; adjustable force application degree of the clamp is achieved, and the work-piece is firmly clamped in a symmetrical clamping manner.
Description
Technical field:
The present invention relates to a kind of stationary fixture, the compound clamping device of especially a kind of double cam.
Background technology:
Anchor clamps and grip device are widely known by the people, and are widely used for manufacturing.Particularly, anchor clamps have various reference surfaces and point, and parts or instrument can accurately be located.In many process, general application anchor clamps are so that these parts can keep correct position relationship in for example punching press, riveted joint, welding, the process of pasting or solidifying.Anchor clamps are considered to requisite parts in the processing industry, and are the vitals of calculating processing cost, also are the vitals that requires in process of production logistics to consider, most position fixing process all utilize anchor clamps to realize.
To carry out vertical and horizontal location to workpiece to be processed now, also will prevent the clamping device of workpiece rotating, its complex structure, fixed effect is bad, and the shortcoming such as manufacturing cost height.
Summary of the invention:
The technical problem to be solved in the present invention is: provide a kind of clamping effective, simple in structure, the anchor clamps of low cost of manufacture.
In order to solve the above problems, the invention provides the compound clamping device of a kind of double cam, comprise clip base, the spring chuck of extruding inner hole of workpiece, the upper end is connected to the chuck pin in the spring chuck, the pressing plate of extruding workpiece sidewall, co-axially fixed chuck pin cam, pressing plate cam and cam handle, described chuck pin bottom is fixed with the nut with chuck pin cam apical grafting, be provided with the spring that the keep-spring chuck struts between nut and the spring chuck, described pressing plate middle part is hinged on the clip base, its drive end and pressing plate cam offset, the sidewall of its driven end butt workpiece.
The fastening of anchor clamps:
In clamping process, the manual rotation cam handle, so that the distal end of chuck pin cam is away from the chuck pin, because spring is in compressive state, spring-relaxation always, spring chuck swelling inner hole of workpiece clamps thereby the chuck pin moves down, because pressing plate cam and the coaxial setting of cam handle, the distal end of pressing plate cam will press pressing plate, so that press plate rotary, with the clamping sides of workpiece, unclamping workpiece only needs the backward rotation handle.
Use the compound clamping device of double cam of technical solution of the present invention that following benefit is arranged: because double-cam structure is set, its transmission efficiency is high, Stability Analysis of Structures, 2, use spring drop-down to the swelling of spring chuck to the chuck pin, its applicable higher environment of flat rate that unclamps jaw.
As preferred version, for so that pressing plate has and automatically replies ability, the lower end of described pressing plate is connected on the clip base by extension spring.
As preferred version, in order to make things convenient for the manufacturing of anchor clamps, described clip base edge is provided with the fore-set platform that withstands the workpiece lower surface.
Description of drawings:
Fig. 1 is the structural representation of the compound clamping device of present embodiment double cam.
The specific embodiment:
Below in conjunction with drawings and Examples technical solution of the present invention is further specified:
As shown in Figure 1: the compound clamping device of a kind of double cam, comprise clip base 1, the spring chuck 9 of extruding inner hole of workpiece, the upper end is connected to the chuck pin 11 in the spring chuck 9, the pressing plate 7 of extruding workpiece sidewall, co-axially fixed chuck pin cam 5, pressing plate cam 4 and cam handle 3, described chuck pin 11 bottoms are fixed with the nut with chuck pin cam 5 apical graftings, be provided with the spring 8 that keep-spring chuck 9 struts between nut and the spring chuck 9, described pressing plate 7 middle parts are hinged on the clip base 1, its drive end and pressing plate cam 4 offset, the sidewall of its driven end butt workpiece.
The fastening of anchor clamps: in clamping process, manual rotation cam handle 3, so that the distal end of chuck pin cam 5 is away from chuck pin 11, because spring 8 is in compressive state, spring 8 diastoles always, spring chuck 9 swelling inner hole of workpieces clamp thereby chuck pin 11 moves down, because pressing plate cam 4 and cam handle 3 coaxial settings, the distal end of pressing plate cam 4 will press pressing plate 7, so that pressing plate 7 rotates, with the clamping sides of workpiece, unclamping workpiece only needs backward rotation cam handle 3.
Because double-cam structure is set, its transmission efficiency is high, Stability Analysis of Structures, use 8 pairs of chuck pins 11 of spring drop-down, thus 9 swellings of spring chuck, its applicable higher environment of frequency that unclamps pressing plate 7, for so that pressing plate 7 has the ability that automatically replies, the lower end of described pressing plate 7 is connected on the clip base 1 by extension spring 6, and in order to make things convenient for the manufacturing of anchor clamps, described clip base 1 edge is provided with the fore-set platform 2 that withstands the workpiece lower surface.
Above-described only is preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away 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 can not affect effect of the invention process and practical applicability.
