Abstract
The utility model discloses a screw locking device. The screw locking device comprises a servo motor, a shaft coupler, a linear slide rail, a screwdriver, a gearbox, a spring, a screw adsorption nozzle and a base, wherein the gearbox is arranged above the base, the spring is arranged between the gearbox and the base, and one side surface of the gearbox is slidably fixed on the base by the linear slide rail; a transmission gear is arranged in the gearbox, and the servo motor is in transmission connection with the transmission gear by the shaft coupler; the screwdriver is rotationally fixed on the gearbox and the screw locking end of the screwdriver penetrates and sleeves in the base, and the transmission gear is in transmission connection with the screwdriver; the screw adsorption nozzle is fixedly arranged on the lower side surface of the base and located below the screwdriver. According to the screw locking device disclosed by the utility model, a torque is accurately output by the torque control mode of the servo motor and transmitted to the screwdriver by the gearbox, the screwdriver stretches out of the device and is capable of locking a screw in a small space, meanwhile, the working noise is low and a manual adjustment is not required.
Description
Technical field
The utility model relates to a kind of lock screw device.
Background technology
At present, existing lock screw device generally can not operation in narrow space, and it is not accurate that lock is paid moment, and need manual adjustment.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of lock screw device, can lock the screw in less space, can precisely control output torque simultaneously.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of lock screw device, comprise servomotor, shaft coupling, linear slide rail, screwdriver, gear-box, spring, screw adsorption mouth and pedestal, described gear-box is located at described pedestal top, described spring is located between this gear-box and pedestal, and a side of described gear-box is slidably fixed on described pedestal by described linear slide rail; In described gear-box, be provided with travelling gear, described servomotor connects this travelling gear by described shaft coupling transmission; Described screwdriver is rotatably fixed on described gear-box and this screwdriver lock screw one end is set in described pedestal, and described travelling gear and this screwdriver are in transmission connection; Described screw adsorption mouth sets firmly to be located on described pedestal downside and to be positioned at described screwdriver below.
As further improvement of the utility model, on described gear-box, be also provided with the screwdriver briquetting for fixing described screwdriver.
The beneficial effects of the utility model are: this lock screw device is by the accurate output torque of Torque Control pattern of servomotor, by gear-box, be transferred on screwdriver, screwdriver stretches out this device, can lock the screw in less space, operating noise is little simultaneously, does not need manual adjustment.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
By reference to the accompanying drawings, make the following instructions:
1---servomotor 2---shaft coupling
3---linear slide rail 4---screwdriver briquetting
5---screwdriver 6---gear-box
7---spring 8---screw adsorption mouth
9---pedestal
The specific embodiment
By reference to the accompanying drawings; the utility model is elaborated; but protection domain of the present utility model is not limited to following embodiment, the simple equivalence of in every case being done with the utility model claim and description changes and modifies, within all still belonging to the utility model patent covering scope.
As shown in Figure 1, a kind of lock screw device, comprise servomotor 1, shaft coupling 2, linear slide rail 3, screwdriver 5, gear-box 6, spring 7, screw adsorption mouth 8 and pedestal 9, described gear-box is located at described pedestal top, described spring is located between this gear-box and pedestal, and a side of described gear-box is slidably fixed on described pedestal by described linear slide rail; In described gear-box, be provided with travelling gear, described servomotor connects this travelling gear by described shaft coupling transmission; Described screwdriver is rotatably fixed on described gear-box and this screwdriver lock screw one end is set in described pedestal, and described travelling gear and this screwdriver are in transmission connection; Described screw adsorption mouth sets firmly to be located on described pedestal downside and to be positioned at described screwdriver below.
Preferably, on described gear-box, be also provided with the screwdriver briquetting 4 for fixing described screwdriver.
During use, first with screw adsorption mouth absorption screw, then gear-box 6 is moved down to holddown spring 7 along linear slide rail 3, now lock screw one end of screwdriver 5 is stretched out outside pedestal 9 and is pushed against on screw, then screw is put into screw, and starting servomotor 1, servomotor 1 transmits torque on screwdriver 5 by shaft joint 2 and the travelling gear (not shown) that is positioned at gear-box 3, realizes lock screw function.Screwdriver briquetting 4 can freely be dismantled, with quick-replaceable screwdriver 5.This lock screw device can precisely be controlled by program the moment of lock screw, to meet high accuracy lock screw occasion.
