Description

Chamfering device for automatic clamping screws

technical field

The utility model relates to the technical field of screw chamfering, in particular to a chamfering device for automatically clamping screws.

Background technique

In the prior art, when chamfering the screw, the screw is usually fixed manually, and the screw is fixed in the headstock fixture, and then the motor can be started to allow the tool to chamfer the screw. This method is not only labor-intensive for operators, but also has very low production efficiency and unsafe operation, so it needs to be improved.

Contents of the invention

The technical problem to be solved by the utility model is to provide an automatic clamping screw chamfering device which is ingenious in design, easy to operate, and can automatically clamp and loosen the chamfering screw in view of the above-mentioned prior art.

The technical solution adopted by the utility model to solve the above-mentioned technical problems is: the chamfering device of the automatic clamping screw includes a positioning frame that can slide back and forth on the chute of the machine tool, and a rotatable positioning frame that is linked with the output shaft of the motor. The cutter, the positioning frame is connected with the first telescopic rod of the cylinder one fixed on the machine tool, and a clamping groove for punching and positioning is arranged laterally on the positioning frame, and the axis line of the screw in the clamping groove is in line with the The axis line of the tool is located on the same straight line, and it is characterized in that: a device that can automatically clamp and loosen the screw placed in the clamping groove is provided in the horizontal and transverse direction sliding with the positioning frame.

As an improvement, the specific structure of the automatic clamping and releasing device can be selected as follows: a second telescopic rod is provided at the position of the clamping groove and the second telescopic rod can extend laterally into the clamping groove to withstand or release Screw the cylinder II.

As a further improvement, the second telescopic rod is connected with the connecting rod of the second cylinder.

As a further improvement, the front end of the second telescopic rod may also be provided with a V-shaped groove capable of fitting screws.

Compared with the prior art, the utility model has the advantages that: the cylinder is skillfully used for fixing the screws, and at the same time, the cylinder and the chute are used for loosening the screws, the design is ingenious, efficient and convenient, and the automatic fixing is fully realized , The technical effect of automatic loosening after chamfering.

Detailed ways

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figures 1 to 4, the chamfering device for automatic clamping screws includes a positioning frame 2 that can slide back and forth on the chute of the machine tool 3, and a rotatable tool 5 that is linked with the output shaft of the motor 4 , the positioning frame 2 is connected with the first telescopic rod 111 of the cylinder one 11 fixed on the machine tool 3, and the clamping groove 21 for chamfering positioning is arranged laterally on the positioning frame 2, and the axis line of the screw in the clamping groove 21 Located on the same straight line as the axis line of the tool 5, a device that can automatically clamp and loosen the screws placed in the clamping groove 21 is provided in the horizontal and transverse direction where the positioning frame 2 slides.

The specific structure of the above-mentioned automatic clamping and loosening device is as follows: a second telescopic rod 121 is provided at the position of the clamping groove 21 and a cylinder 2 that enables the second telescopic rod 121 to extend laterally into the clamping groove 21 to withstand or loosen the screw. 12. The second telescopic rod 121 is connected with the connecting rod of the cylinder two 12. The front end of the second telescopic rod 121 is provided with a V-shaped groove capable of fitting a screw.

Working principle: Start the motor 4, the cutter 5 starts to rotate, put the screw into the front end of the clamping groove 21, the cylinder 2 12 starts to work, push the second telescopic rod 121 to the front end of the clamping groove 21, the second telescopic rod 121 and the positioning The frame 2 clamps the screw, and the hand can be removed at this time; then the cylinder one 11 starts to work, pushes the positioning frame 2 to slide in the direction of the motor 4 through the first telescopic rod 111, and the cutter 5 chamfers the screw; when the chamfering is completed , Cylinder one 11 makes the positioning frame 2 slide back through the first telescopic rod 111 again, and simultaneously cylinder two 12 makes the second telescopic rod 121 shrink in the opposite direction, and the screw can be moved out.
