Abstract
The invention relates to a fixed fixture, in particular to a cam thrust fixture which comprises a fixture body, a power shaft used as a force application device, a cam, a rocking arm, a sliding pin, a push rod and a clamping jaw shaft which are used as driving devices, and a clamping jaw used for clamping workpieces, wherein one end of the power shaft is provided with racks meshed with teeth on the large-diameter part of the cam hinged on the fixture body; the sliding pin is slidably arranged on the fixture body and respectively props against the small-diameter part of the cam and the force application end of the rocking arm; the rocking arm is hinged on the fixture body, the power end of the rocking arm props against the push rod; the push rod is in bolted connected with the force application end of the clamping shaft; and the clamping jaw is a V-shaped slotted claw and is fixedly arranged at the driven end of the clamping jaw shaft by virtue of a screw rod. The cam thrust fixture has the beneficial effects of smart and reasonable arrangement and firm clamping.
Description
Technical field:
The present invention relates to a kind of stationary fixture, especially a kind of cam thrust force anchor clamps.
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.
Use cam as clamp and the transmission of unclamping, it is this area conventional means, but relate to the structure restriction of anchor clamps itself, how cam plays cleverly utilization at anchor clamps, it is the important research object of the art, particularly for the situation of coming clamping work pieces with thrust, the miscellaneous part of cam and anchor clamps cooperates the thrust anchor clamps of important normal operation particularly owing to the structure of environment for use and anchor clamps itself, usually so that clamping is not firm.
Summary of the invention:
The technical problem to be solved in the present invention is: provide a kind of cam that utilizes to be drive mechanism, and the thrust anchor clamps of reliable clamping.
In order to solve the above problems, the invention provides a kind of cam thrust force anchor clamps, include chuck body, line shaft as force application apparatus, cam as transmission device; rocking arm; sliding pin; push rod and jaw axle; as the jaw of clamping work pieces; described line shaft one end is provided with tooth bar and is meshed with more than half path portion teeth of cam on being hinged on chuck body; described sliding pin is slidingly arranged on the chuck body; and offset respectively with the minor radius part of cam and the force side of rocking arm; described rocking arm is hinged on the chuck body; its power end and push rod offset; this push rod is connected with the force side bolt of described jaw axle, and described jaw is the driven end that V-type groove pawl and screw rod are fixed in the jaw axle.
Use the cam thrust force anchor clamps of technical solution of the present invention that following benefit is arranged: 1, have more than half path portion and minor radius part Combined cam owing to use, play the effect of a transmission and labour-saving; 2, described jaw is the driven end that V-type groove pawl and screw rod are fixed in the jaw axle so that clamp firm.
As preferred version, for so that jaw has a function that automatically replies, the force side of described jaw axle is provided with screw rod and is placed in returning spring on the screw rod, and the preformed hole that described cover has the screw rod of returning spring to pass clip base is connected with the jaw axle bolt.
As preferred version, in order to prevent the jaw axle along described push rod radial rotary, the force side of described jaw axle is provided with stopper slot, and this stopper slot and the steady pin clamping that is fixed on the chuck body cooperate.
Description of drawings:
Fig. 1 is the structural representation of present embodiment cam thrust force anchor clamps.
The specific embodiment:
Below in conjunction with drawings and Examples technical solution of the present invention is further specified:
As shown in Figure 1: a kind of cam thrust force anchor clamps, include chuck body 1, line shaft 2 as force application apparatus, cam 10 as transmission device; Rocker arm 4; sliding pin 3; push rod 5 and jaw axle 6; as the jaw 7 of clamping work pieces; an end of line shaft 2 be provided with tooth bar and and more than half path portion heel teeth tooth of cam 10 be meshed; sliding pin 3 is slidingly arranged on the chuck body 1; and offset respectively with the minor radius part of cam 10 and the force side of Rocker arm 4; Rocker arm 4 is hinged on the chuck body 1; power end of Rocker arm 4 and push rod 5 offset, and push rod 5 is connected with the force side bolt of jaw axle 6, and jaw 7 is the driven end that V-type groove pawl and screw rod are fixed in jaw axle 6.
Have more than half path portion and minor radius part Combined cam 10 owing to use, play the effect of a transmission and labour-saving, jaw 7 is the driven end that V-type groove pawl and screw rod are fixed in jaw axle 6, so that clamp is firm.
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.
