Abstract

The utility model discloses a torsion machine. The machine comprises a motor and a guide rod and a torsion driving shaft which are perpendicular to the motor, wherein the guide rod is connected with a rotating shaft of the motor; a sliding plate seat capable of sliding up and down is arranged on the guide rod and connected with a transmission shaft of a cylinder arranged below the sliding plate seat; a torque sensor is arranged on the torsion driving shaft; a die chuck for clamping a workpiece is arranged at the lower end of the torsion driving shaft; the torque sensor and the sliding plate seat are positioned at the same height and connected; the cylinder is connected to a bracket; the bracket is connected with a bottom plate seat; and the motor is arranged on the bottom plate seat. The machine is high in production speed, the downward pushing speed of the torsion driving shaft is balanced, and torsion during positive and negative rotation is uniform and controllable; and when rotating torsion reaches a set torsion value, the motor automatically stops tightening, the workpiece is firmly clamped, and accuracy is high.

Description

A kind of torsion machine

Technical field

The utility model relates to a kind of torsion machine.

Background technology

What torsion machine in the past adopted mostly is hydraulicdriven; Relied on air pressure experiment chuck to advance before this downwards; After putting in place, chuck decline rely on oil pressure to realize rotating; Because the torsion machine of this kind structure receives the influence of air pressure and oil temperature easily, advance downwards and the power of rotating inhomogeneous, be easy to generate defective products.

The utility model content

In order to overcome the defective that above-mentioned prior art exists, the utility model provides a kind of torsion machine, guarantees that the speed that advances under the torsion driving axial is balanced; Torsion homogeneous and controllable during rotating; Adopt torque sensor to detect and show and the setting torque value that the clamping workpiece accuracy is more accurate, and is easy to adjust.

To achieve these goals, the technical scheme of the utility model is following:

A kind of torsion machine; Comprise motor, vertical vertical guide post and the torsion driving shaft of installing with motor drive direction, said guide post links to each other with the rotating shaft of motor; The slide plate chair that can slide up and down is set on the guide post, and the power transmission shaft of cylinder links to each other said slide plate chair with installing thereunder; Mounting torque sensor on the said torsion driving shaft, the lower end of torsion driving shaft are provided for the mould chuck of clamping workpiece, and said torque sensor is in sustained height with the slide plate chair position and is connected.

Further, said cylinder is connected on the support, is connected with bottom block on the said support, and above-mentioned motor is installed on the bottom block.

Place the workpiece be used for clamping on the said support, when the mould holder head grasps workpiece, show the torque value of clamping, and can regulate and reset adjustment through torque sensor.

The operation principle of the utility model is:

Motor rotates; Drive the guide post rotation that links to each other through rotating shaft; The guide post rotation drives the torsion driving shaft and torque sensor rotates; Make mould holder head-clamp clamping of workpieces through driven by motor torsion driving shaft, and on torque sensor, show torque value, motor will stop to tighten automatically when torsion reaches the setting torque value.

When needs during to mould chuck up-down adjustment; Cylinder through rack-mount is regulated; Piston promotion power transmission shaft moves the continuous slide plate chair of drive and slides up and down along guide post; Said slide plate chair links to each other with torque sensor, and said torque sensor and torsion driving shaft are followed slide plate chair and moved up and down together, use locked with bolts when moving into place.

The beneficial effect of the utility model is, guarantees that the speed that advances is balanced downwards, the torsion homogeneous and controllable during rotating, and speed of production is adjustable, and torque value can be set as required; Through torque sensor torque value is shown and the setting adjustment that detection shows convenient, and the people is regulated more intuitively, the clamping workpiece is more fastening.

Fig. 1 is the structural representation of the utility model.

Among the figure, 1, the torsion driving shaft, 2, motor, 3, torque sensor, 4, slide plate chair, 5, guide post, 6, the mould chuck, 7, bottom block, 8, cylinder, 9, support.

The specific embodiment:

For the creation characteristic, the technological means that make the utility model and reach purpose and be easy to understand and understand, further set forth the utility model below in conjunction with specific embodiment.

Embodiment:

Referring to Fig. 1, a kind of torsion machine comprises support 9; Be connected the bottom block 7 on the support 9, be installed in motor 2 on the bottom block 7, the guide post 5 of the vertical placement that links to each other with motor 2 rotating shafts; With guide post 5 parallel placements and the torsion driving shaft 1 that links to each other with motor 2, torque sensor 3 is installed on the torsion driving shaft 1, the end of torsion driving shaft 1 connects mould chuck 6; Slide plate chair 4 is installed on the guide post 5, and slide plate chair 4 is in sustained height with torque sensor 3 and is connected, and the bottom of slide plate chair 4 links to each other with the power transmission shaft of cylinder 8; Drive the telescopic transmission shaft motion through piston in the cylinder 8; Move up and down along guide post 5 thereby drive the slide plate chair 4 that links to each other, thereby drive torque sensor 3 and torsion driving shaft 1 move up and down, the mould chuck 6 that torque transmission axle 1 bottom is connected moves to the location of workpiece of clamping.

During motor 2 operations, drive guide post 5 rotations that link to each other through rotating shaft, guide post 5 drives the slide plate chair 4 that links to each other and horizontally rotates, and the 3 pairs of torque values of torque sensor that are connected are regulated, and makes mould chuck 6 clamping workpiece reach desired optimum state.

The utility model speed of production is adjustable, guarantees under the torsion driving axial that the speed that advances is balanced, the torsion homogeneous and controllable during rotating, and when rotary torsion reaches the setting torque value, motor will stop to tighten automatically, and the clamping workpiece is more fastening.The demonstration of torque value is to adopt torque sensor to detect demonstration with setting adjustment, regulates more convenient.

More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
