Abstract

The utility model discloses a clamping device driven by a gear and a rack. The clamping device is used for solving the problem that according to an existing clamping device, drive is unstable. The clamping device comprises a base, a clamping platform and a press plate. The clamping device is characterized by further comprising an operating rod, the gear, the rack and a pressing rod, wherein the operating rod is connected with the gear, the gear is meshed with the rack, one end of the rack is connected with one end of the pressing rod, the middle of the pressing rod is hinged, the other end of the pressing rod is connected with one end of the press plate, the gear is arranged in a groove formed in the middle of the base, the rack is arranged on the top of the base, the pressing rod is arranged on one side of the clamping platform, the press plate is arranged on the top of the clamping platform, and a V-shaped clamping portion is arranged at the position, opposite to the press plate, of the top of the clamping platform. According to the clamping device driven by the gear and the rack, drive is stable when clamping motions are carried out, and clamping locating is accurate.

Description

The clamping device of rack-and-pinion transmission
Technical field
The utility model relates to Machining Technology, is specifically related to a kind of clamping device of rack-and-pinion transmission.
Background technology
clamping device is widely used in the processing and manufacturing of component of machine, at present, existing clamping device is generally by cylinder or oil cylinder direct tape splicing dynamic pressure plate or jaw action clamping work pieces, and such kind of drive often exists the unsettled problem of transmission, causes the clamping action of workpiece inaccurate.
Utility model content
The utility model provides a kind of clamping device of rack-and-pinion transmission, the unsettled problem of transmission existing to solve existing clamping device.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
The clamping device of rack-and-pinion transmission, comprise pedestal, grain-clamping table and pressing plate, also comprise action bars, gear, tooth bar and compressor arm, described action bars is connected with gear, wheel and rack engagement, one end of tooth bar is connected with one end of compressor arm, the middle part of compressor arm is hinged, the other end of compressor arm is connected with pressing plate one end, gear is arranged in the groove of offering at pedestal middle part, and tooth bar is located at pedestal top, and compressor arm is arranged on a side of grain-clamping table, pressing plate is arranged on grain-clamping table top, and the position relative with pressing plate, grain-clamping table top is provided with V-arrangement clamping part.
The beneficial effects of the utility model: this clamping device is by the transmission of rack-and-pinion, the action of drive compressor arm, and then drive presser motion by compressor arm, realize the clamping of workpiece and unclamp, clamp than cylinder or oil cylinder direct tape splicing dynamic pressure plate, have transmission stable, holding action is advantage accurately.
Further, between compressor arm and grain-clamping table, be provided with back-moving spring on described compressor arm top.In the time discharging workpiece, back-moving spring can make compressor arm, rack and pinion automatically reset, handled easily.
Brief description of the drawings
Fig. 1 is the structural representation of the clamping device embodiment of the utility model rack-and-pinion transmission.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The clamping device of rack-and-pinion transmission as shown in Figure 1, comprise pedestal 1, grain-clamping table 2, action bars 3, gear 4, tooth bar 5, compressor arm 6, pressing plate 7, V-arrangement clamping part 8 and pressing plate reseasable tip 9, action bars is connected with gear, wheel and rack engagement, one end of tooth bar is connected with one end of compressor arm, the middle part of compressor arm is hinged, the other end of compressor arm is connected with pressing plate one end, gear is arranged in the groove of offering at pedestal middle part, tooth bar is located at pedestal top, compressor arm is arranged on a side of grain-clamping table, pressing plate is arranged on grain-clamping table top, the position relative with pressing plate, grain-clamping table top arranges V-arrangement clamping part, between compressor arm and grain-clamping table, be provided with back-moving spring (not shown) on compressor arm top.
Its operation principle of this clamping device is as follows: pull action bars, action bars driven gear rolls forward in the groove of pedestal, wheel and rack engagement, thereby tooth bar also travels forward thereupon, tooth bar end is connected with compressor arm one end (being lower end in the present embodiment), therefore outside the bottom of the moving compressor arm of the Sports band of tooth bar, put, compressor arm middle part is hinged, therefore the top of compressor arm is drawn close interior pendulum band dynamic pressure plate to the motion of V-arrangement clamping part, until clamping work pieces, discharge workpiece action contrary, discharging workpiece can manual operation, also can be realized by back-moving spring.
In the present embodiment, bare terminal end at pressing plate is provided with reseasable tip, reseasable tip has the bevel phase of inclination, in the time that side surface of workpiece to be held is plane, this end can be unloaded, in the time that side surface of workpiece to be held is inclined-plane, this end can be installed, to match with the profile of workpiece, make the clamping of workpiece more firm, can clamp the workpiece with different profiles, make this clamping device have more practicality simultaneously.
