Abstract
The invention relates to a fine tuning compressing device. The fine tuning compressing device comprises an outer shell, and a compressing rod is arranged in the outer shell. The fine tuning compressing device is charterized by further comprising an adjusting mechanism; the adjusting mechanism comprises a rotating pin connected with the lateral wall of the outer shell, a swing rod in the direction the same as the axial direction of the compressing rod is connected to the rotating pin, an adjusting rod is arranged on the upper end face of the outer shell, the adjusting rod is vertical to the swing rod and penetrates through the swing rod, a spring is arranged on one side of the position, located between the swing rod and the outer shell, of the adjusting rod, and an adjusting nut is arranged on the other side of the position, located between the swing rod and the outer shell, of the adjusting rod. The fine tuning compressing device further comprises a push rod connected with the top end of the swing rod, and the push rod is in contact with the top end of the compressing rod. The fine tuning compressing device is mainly used for conducting compression processing on precise tools, compressing force is adjusted finely, the tools are prevented from being damaged, and practicability is achieved.
Description
Technical field
The present invention relates to tool fitting field, particularly point out the fine setting hold down gag for fixing fine parts.
Background technology
To in the fixation procedure of workpiece, usually adopt fixture to be fixed, conventional brace, when fixing, be mostly rigid formula and fix, and in addition, also has and adopts thimble to be fixed, and thimble is easy especially when fixing forms damage to surface of the work.
Summary of the invention
The object of the invention is to propose fine setting hold down gag, be mainly used in the compression process to accurate instrument, realize trace and regulate thrust, protection instrument is injury-free, has practicality.
The technical scheme realizing the object of the invention is as follows:
Fine setting hold down gag, comprise shell body, compressor arm is provided with in described shell body, it is characterized in that, also comprise governor motion, described governor motion comprises the rotational pin be connected with shell body sidewall, closure and the axial swing arm in the same way of compressor arm on trundle, described shell body upper surface is provided with adjusting rod, described adjusting rod and swing arm are mutually vertical, and through swing arm, on adjusting rod, between swing arm and shell body, side is provided with spring, opposite side is provided with adjusting nut, also comprise the catch bar be connected with swing arm top, described catch bar contacts with the top of compressor arm.
Further, described compressor arm comprises compressor arm body, and compressor arm body lower end is provided with briquetting, and described compressor arm body is connected by the second spring with between briquetting, and the second described spring one end is connected in the depression of compressor arm body lower end.
Further, be connected through the hinge between described catch bar and swing arm.
Further, described rotational pin is connected on shell body by expansion link, and the inactive side of described expansion link is fixedly connected with shell body.
After adopting said structure, the invention has the beneficial effects as follows: by regulating described adjusting nut, described swing arm is regulated, the direction of motion of swing arm be outside housing sidewall near or under the action of the spring away from shell body sidewall, due to the motion of swing arm, the motion of catch bar will be driven, catch bar again with compressor arm upper-end contact, compressor arm will move up and down thus, overall structure is under the operation of adjusting nut, eventually through arm of force transmission, adjustment is produced to compressor arm, and its regulated quantity is micro-, has larger practicality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fine setting hold down gag, comprise shell body 1, compressor arm 2 is provided with in described shell body 1, also comprise governor motion, described governor motion comprises the rotational pin 3 be connected with shell body sidewall, closure and the axial swing arm 4 in the same way of compressor arm 2 on trundle 3, described shell body 1 upper surface is provided with adjusting rod 5, described adjusting rod 5 is mutually vertical with swing arm 4, and through swing arm 4, on adjusting rod 5, between swing arm and shell body, side is provided with spring 6, opposite side is provided with adjusting nut 7, also comprise the catch bar 8 be connected with swing arm 4 top, described catch bar 8 contacts with the top of compressor arm 2.
Specifically, by regulating described adjusting nut, described swing arm is regulated, the direction of motion of swing arm be outside housing sidewall near or under the action of the spring away from shell body sidewall, due to the motion of swing arm, to the motion of catch bar be driven, catch bar again with compressor arm upper-end contact, compressor arm will move up and down thus, overall structure is under the operation of adjusting nut, produce adjustment eventually through arm of force transmission to compressor arm, and its regulated quantity is micro-, reason comprises:
1. the adjusting nut described in is positioned at the center of swing arm, to the similar lever regulate of the adjustment of swing arm;
2. the catch bar described in is followed the motion of swing arm and moves, but motion amplitude will be less than swing arm;
3. the catch bar described in forms promotion relation to compressor arm, and because the sports between catch bar and compressor arm is angled, amount of exercise is not etc. yet separately for it.
Described compressor arm comprises compressor arm body, and compressor arm body lower end is provided with briquetting, and described compressor arm body is connected by the second spring 9 with between briquetting, and the second described spring one end is connected in the depression of compressor arm body lower end.Adopt the compressor arm of said structure can realize the buffering of pressure, reduce the damage to workpiece further.
10 are connected through the hinge between described catch bar and swing arm.
Described rotational pin is connected on shell body by expansion link 11, and the inactive side of described expansion link is fixedly connected with shell body.Adopt this kind of structure, the distance between rotational pin and shell body is adjustable, further can realize the amplitude of fluctuation controlling swing arm, thus realizes optimizing further to fine setting.
Claims (4)
