Abstract
The utility model discloses a kind of eccentric clamp system, comprise gear shaft, handle, body is characterized in that eccentric hoop, eccentric adjusting sleeve, spring, straight pin, straight pin inserts in the locating hole on eccentric adjusting sleeve, eccentric strap is on eccentric adjusting sleeve, rotating eccentric sleeve cylinder, the open end of inclined sleeve is abutted in straight pin, the other end of opening and straight pin spring are coupled together, gear shaft is through body center hole, eccentric adjusting sleeve and gear shaft are linked together, the end face circular bosses of eccentric adjusting sleeve is passed with the center sky of flange, empty through the circumference on flange with bolt, flange and body are connected and fixed, clamping loose unloading is completed by turning handle.This eccentric clamp system place different from common eccentric clamp system be convenient to regulate clamping force, change traditional clamping point certain, the change in size of processing work is, can not the problem of clamping work pieces completely in clamping.
Description
Technical field
The utility model relates to a kind of retaining mechanism, especially can according to the eccentric locking mechanism of workpiece size adjustment.
Background technology
Along with industrial development, part processing is more and more, and be all Workpiece fixing will be stepped up at numerous processing modes, the size of Workpiece clamping power directly affects the positioning precision of workpiece, and the position of the clamping point of current eccentric clamp system is constant, and the size of the workpiece of processing fluctuates within the specific limits, and just can only for a kind of clamping of part with a clamp system, which results in waste, have impact on the accurate of locating and machining, cause the precision affecting processing.
Summary of the invention
The purpose of this utility model is to change current eccentric clamp system the deficiency causing clamping force because of the change of the size of clamping part, and the clamping device present situation that can only use on a kind of part and a kind of novel eccentric clamp system proposed, make it possible to the clamp system regulated because of the change of clamping work pieces size, the size of clamping force is ensured.
For achieving the above object, the technical solution of the utility model is: a kind of eccentric clamp system, comprise gear shaft, handle, body, eccentric hoop, eccentric adjusting sleeve, spring, straight pin, straight pin inserts in the locating hole on eccentric adjusting sleeve, eccentric strap is on eccentric adjusting sleeve, then rotating eccentric sleeve cylinder, the open end of inclined sleeve is abutted in above straight pin, the other end of opening and straight pin spring are coupled together, gear shaft is through the circular hole of body, eccentric adjusting sleeve and gear shaft are linked together, the end face garden boss of eccentric adjusting sleeve is passed with the center sky of flange, by the circumferential apertures on flange, with bolt, flange and body are connected and fixed, every day use is then by handle is completed clamping loose unloading.
In technique scheme, the eccentric clamp system adopted is different from common eccentric clamp system, by the rotation of handle, finally can move on gear shaft, then the wheel and rack engagement on sprocket drive spindle, convert circular motion to rectilinear motion, when tooth bar lower end workpiece pressing, when can not move downward again, being rotated further of eccentric adjusting sleeve, in the wedge gap that the wedge-like portion of eccentric adjusting sleeve is expressed between body and eccentric hoop, thus achieve the clamping of workpiece.
Improve as the first step of the present utility model, axle and eccentric hoop are connected by key, can realize the synchronous axial system of axle and eccentric hoop like this.
Improve as second step of the present utility model, axle and eccentric hoop connecting key are woodruff keies, and mainly consider that this keyway position is axle head, the load simultaneously connecting work is little.
Improve as three steps of the present utility model, the square opening of handle end coordinates with the square boss on eccentric adjusting sleeve end face boss, realize the rotation of handle, adopt this demountable turning handle, can ensure accidentally to touch in process change clamping force that turning handle brings and save space.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the overall design drawing of a kind of eccentric clamp system of the utility model;
Fig. 2 is the A-A sectional view that Fig. 1 plants eccentric clamp system;
Mark in above-mentioned figure is: gear shaft 1, eccentric hoop 2, eccentric adjusting sleeve 3, handle 4, spring 5, straight pin 6, body 7, half round pin 8, square boss 9, flange 10.
Detailed description of the invention
Embodiment of the present utility model as depicted in figs. 1 and 2, comprises gear shaft 1, eccentric hoop 2, eccentric adjusting sleeve 3, handle 4, spring 5, straight pin 6, body 7, half round pin 8, flange 10.
Straight pin 6 is inserted in the locating hole on eccentric adjusting sleeve 3, eccentric hoop 2 is enclosed within eccentric adjusting sleeve 3, then rotating eccentric sleeve cylinder 3, the open end of inclined sleeve 3 is abutted in above straight pin 6, then the other end of opening and straight pin 6 spring 5 are coupled together, gear shaft 1 is installed the circular hole of woodruff key 8 end through body 7, be connected with the woodruff key on gear shaft 1 with the keyway of eccentric adjusting sleeve 3, the end face garden boss of eccentric adjusting sleeve 3 is passed with the center sky of flange 10, by the circumferential apertures on flange 10, with bolt, flange 10 and body are connected and fixed, every day use is then by being coordinated with the square boss on eccentric adjusting sleeve 3 end face boss by the square opening of handle 4 end, last turning handle 4 can use.The clamp segment of this eccentric clamp system is mainly connected with the tooth bar on clamp body by gear shaft 1, and moving up and down finally by tooth bar, adds clamping of workpieces.
This eccentric clamp system is mainly by turning handle 4, eccentric adjusting sleeve 3 is driven to rotate, eccentric adjusting sleeve 3 is by straight pin 6 transmission eccentric hoop 2, eccentric hoop 2 is by woodruff key 8 driving gearshaft 1, gear shaft 1 to be cogged driving rack by axle, complete and circular motion is transformed rectilinear motion, when the lower end of tooth bar touches workpiece, until after clamping, and tooth bar, cannot when action with gear shaft 1, due to being rotated further of handle 4, cause being rotated further of eccentric adjusting sleeve 3, in the wedge gap that the wedge-like portion of eccentric adjusting sleeve 3 is expressed between body 7 and eccentric hoop 2, thus achieve the clamping of workpiece.
When processing workpiece, handle 4 direction rotates, and under the effect of straight pin 6 and spring 5, the wedge-like portion that eccentric adjusting sleeve 3 is extruded withdraws from the wedge gap between body 7 and eccentric hoop 2, thus realize the reversion of gear shaft, reach the object unloading workpiece.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; without departing from the concept of the premise utility; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
