Abstract
The utility model relates to a mechanical tool for disassembling or assembling screws, which can convert parallel translation to rotation. The utility model comprises a driving rack bar doing linear motion, a sliding drive gear and an output shaft with a driven gear, wherein the output shaft is connected with a connecting head capable of wearing a sleeve barrel or a scroll rod for disassembling screws. The utility model provides a novel mechanical tool for disassembling or assembling screws. The tool converts the parallel translation to the rotation by a gear cluster, and performs self-return by a spring. When used, the utility model not only has the advantage of no limitation of rotary amplitude, but also has the advantages of continuous work and higher work efficiency.
Description
Technical field
The utility model relates to a kind of instrument of dismounting screw, and is especially a kind of with the parallel machine tool that moves the dismounting screw that changes into rotation.
Background technology
The machine tool that prior art is used for the dismounting screw is various, we are when these instruments of use, all be to give rotating moment of instrument, that is to say and want turning tool just can make the screw degree of tightness, this working method is subjected to the influence that instrument can rotate amplitude, and because the complexity of Workpiece structure, under a lot of situations, the rotatable in use amplitude of instrument is limited, makes work discontinuous, and efficient is not high.
Summary of the invention
The purpose of this utility model is: in order to overcome the deficiencies in the prior art, a kind of parallel moving changed into rotation thereby design, instrument in use can not be subjected to the restriction of rotation amplitude, the machine tool of the dismounting screw of increasing work efficiency.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of machine tool of dismounting screw, contain tooth bar, gear and shell, it is characterized in that: tooth bar is the active tooth bar, and gear is the travelling gear and the driven gear of slip; Initiatively tooth bar and the travelling gear of the slip driven gear that is connected the chieftain on output shaft with the instrument that is equipped with that matches is meshed.
Above-mentioned technical problem of the present utility model can also be further perfect, as preferably, is provided with an end above the described tooth bar and is hinged mutually with matrix, and be the depression bar of fulcrum with the tooth bar.
As preferably, described depression bar links to each other with the compression spring.
As preferably, described shell both sides are provided with vertical guide groove, and the axle of described travelling gear is arranged in vertical guide groove with matching.
As preferably, described shell end face is provided with two tooth bar pilot holes.
As preferably, described tooth bar is arranged on a side of travelling gear.
Therefore, the beneficial effects of the utility model are: in order to overcome the existing instrument not high deficiency that is subjected to the restriction of rotation amplitude of efficient in use, the utility model provides a kind of machine tool of novel dismounting screw, this instrument passes through gear train, parallel moving changed into rotation, and by the spring self-return.Both there be not the restriction of rotation amplitude in use, again can continuous operation, increase work efficiency greatly.
Description of drawings
Accompanying drawing 1 is a kind of duty schematic diagram of the present utility model;
Accompanying drawing 2 is another kind of duty schematic diagrams of the present utility model;
Accompanying drawing 3 is another duty schematic diagram of the present utility model.
The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment: as shown in Figure 1, the active tooth bar 3 that inserts from the tooth bar pilot hole of shell one side is installed in shell 7, initiatively above the tooth bar 3 depression bar 1 is arranged, one end of depression bar is hinged mutually with matrix, and be fulcrum with tie point with the active tooth bar, compression spring 6 is arranged below depression bar, travelling gear 2 matches with active tooth bar 3, the gear shaft 8 of travelling gear 2 is installed in the guide groove 9 of shell 7, the driven gear 4 and the output shaft 5 that can be meshed with travelling gear 2 are arranged below travelling gear 2, the instrument that is equipped with on the output shaft 5 connects the chieftain, and driving gear set shown in the figure and driven gear are bevel gear.Be the state that inserts from the opposite side pilot hole of shell 7 of tooth bar 3 initiatively as shown in Figure 2, at this moment, the direction of rotation of driven gear output shaft is opposite with direction of rotation among Fig. 1.As shown in Figure 3, driving gear set and driven gear are the duty of post tooth.
The concrete course of work is: when downward pushing depression bar 1, compression spring 6 shrinks, initiatively tooth bar 3 motion downwards in the tooth bar pilot hole, drive travelling gear 2 earlier to lower slider, when driving gearshaft 8 slides into guiding supported hole 9 lower ends, this moment travelling gear 2 with driven gear 4 engagements, initiatively tooth bar 3 drives travelling gears 2 and rotates subsequently, and is transferred to driven tooth gear 4 and makes it to turn left together with output shaft 5.The end of output shaft 5 is equipped with instrument and is connected the chieftain, connects sleeve or scroll bar that the chieftain can wear existing dismounting screw.When unclamping depression bar 1, compression spring 6 is upheld, drive depression bar 1 together with active tooth bar 3 returns, initiatively tooth bar 3 elder generations drive travelling gear 2 is vertically upwards sliding in the guide groove 9 simultaneously, when driving gearshaft 8 slided into the upper end of vertical guide groove 9, this moment, travelling gear 2 separated with driven gear 4, dallied with final drive gear, initiatively tooth bar 3 and depression bar 1 are got back to original position automatically under the effect of compression spring 6.If initiatively tooth bar 3 inserts from another tooth bar pilot hole, initiatively tooth bar is opposite with the gear direction of rotation of travelling gear, the driven gear counter-rotating that is meshed with travelling gear, and output shaft 5 turns right.Make it to reach with parallel and move the effect that changes into rotation, and play the purpose that screws and unclamp screw.
