Abstract
The utility model provides an electric chuck which solves the problems that an existing chuck can not clamp stably, and even clamped objects come off due to the fact that clamps of an existing chuck can loose easily. The electric chuck comprises two clamps and an opening and closing mechanism. The opening and closing mechanism comprises a motor and a control rod. One end of the control rod is connected with an output shaft of the motor. A gear part is arranged at one end of each clamp. The other end of the control rod is sleeved with a nut tooth row. The two clamps are respectively arranged on the two sides of the nut tooth row, and the gear tooth parts are meshed with the nut tooth row. Through the control rod, the motor drives the nut tooth row to move forward or backward.
Description
Technical field
The utility model relates to a kind of clamping device, particularly a kind of electric cartridge.
Background technology
In workpiece process, often need to assist clamping or fixing to workpiece, to facilitate, workpiece is processed.Existing piece-holder, fixing mode are mainly to adopt the chuck clamping.The clamp manner of chuck has the clamping of manual clamping and power, and manually clamping by the clamp folding, is limited by people's hand strength with manpower, can only be in the situation that some quality of clamping are light or less use of active force that produce when processing.And the power clamping is to drive the clamp folding with cylinder, can produce the clamping strength larger than manual clamping.Cylinder needs an air pressure driving arrangement, takes up room large, uses dumb, and the chuck of cylinder-pushed is in the clamping object, when particularly object being carried out to bending action, clamp is easily loosening, cause clamping unstable, even cause gripped object to come off.
The utility model content
The utility model proposes a kind of electric cartridge, the clamp that has solved existing chuck easily becomes flexible, causes clamping built on the sand, the problem such as even cause that gripped object comes off.
The technical solution of the utility model is achieved in that
A kind of electric cartridge, comprise two clamps and switching mechanism, and described switching mechanism comprises motor and control lever, and an end of described control lever is connected with the output shaft of described motor, and an end of described clamp is provided with gear teeth section; The other end of described control lever is set with a nut tooth row; Two described clamps are loaded on respectively the both sides of described nut tooth row, and described gear teeth section and described nut tooth row intermeshing; Described motor drives described nut tooth row by described control lever and advances or retreat.
Further, described control lever is screw rod, and the internal ring wall of described nut tooth row is provided with the internal thread be meshed with the external screw thread of described screw rod, the described bolt rotary of described Electric Machine Control.
Further, described a kind of electric cartridge, also comprise shell, and described control lever is packaged in described shell; Described clamp rotates and is installed in described shell by described gear teeth section, and described gear teeth section is packaged in described shell fully.
Further, jump ring is equipped with in the junction of the output shaft of described motor and described control lever.
Further, the cross section of described nut tooth row is square or circle or polygon.
Known by above description, the utility model compared with prior art, the utlity model has following advantage:
The utility model adopts the activity of driven by motor clamp, have that volume is little, cost is low, failure rate is low etc. a little, utilize the outputting power locking of motor, make clamp be difficult for unclamping, clamping firmly, stable.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Structural representation when Fig. 1 is the merging of the utility model clamp.
Fig. 2 is the structural representation of the utility model clamp while opening.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
With reference to Fig. 1, a kind of electric cartridge, comprise shell 4, clamp 1 and switching mechanism, described clamp 1 comprises two clamp 1a, 1b, described switching mechanism comprises motor 21 and control lever 22, one end of described control lever 22 is connected with the output shaft of described motor 21, and an end of described clamp is provided with gear teeth section 11; The other end of described control lever 22 is set with a nut tooth row 3; The cross section of described nut tooth row 3 is square or polygon.Two described clamp 1a, 1b are loaded on respectively the both sides of described nut tooth row 3, and described gear teeth section 11 is intermeshing with described nut tooth row 3; Described motor 21 drives described nut tooth row 3 by described control lever 22 and advances or retreat.Described control lever 22 is packaged in described shell 4; Described clamp 1 rotates and is installed in described shell 4 by described gear teeth section 11, and described gear teeth section 11 is packaged in described shell 4 fully.Jump ring 5 is equipped with in the junction of the output shaft of described motor 21 and described control lever 22.Described jump ring 5 can limit described nut tooth row 3 displacements, touches the output shaft of motor 21 when avoiding described nut tooth row 3 to retreat.
With reference to Fig. 1, described control lever 22 is screw rod, the internal ring wall of described nut tooth row 3 is provided with the internal thread be meshed with the external screw thread of described screw rod, described motor 21 is controlled described bolt rotary, can be so that nut teeth row 3 moves forward or retreats along screw flight, have and control simple advantage, and the internal thread of the external screw thread of screw rod and nut tooth row 3 can assist and prevent that described nut tooth row 3 from moving, make the clamp clamping more firm.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
