Description

Technical Field

[0001] The utility model relates to the field of pipe cutting machines, and more specifically, to a novel pipe cutting machine. Background Art

[0002] Currently, when people cut a pipe, they use a clamp to clamp one side of the pipe, and then translate the pipe cutting device so that the pipe cutting device cuts the pipe.

[0003] However, after in-depth application, people found that if the clamp is only used to clamp the pipe near the cutting position, if the pipe is long, the tail of the pipe will vibrate, which will affect the flatness of the cut. If a clamp is also set at the end of the pipe to clamp the pipe, since the end of the pipe is not necessarily on the same plane as the front end of the pipe, using a traditional clamp to clamp the tail of the pipe will greatly increase the time required for clamping. Therefore, how to quickly clamp and fix the end of the pipe is an urgent problem that needs to be solved in the current pipe cutting process.

[0004] Therefore, it is necessary to propose a new pipe cutting machine that solves the above problems. Utility Model Content

[0005] The present invention provides a new pipe cutting machine in order to overcome at least one defect (shortcoming) of the above-mentioned prior art.

[0006] In order to solve the above technical problems, the technical solution of the present utility model is as follows: a new pipe cutting machine includes a base plate, a pipe cutting device and a clamp for clamping the front end of the pipe, and also includes an auxiliary clamp for clamping the end of the pipe;

[0007] The bottom plate is evenly provided with limiting grooves, and the pipe cutting device is arranged on the bottom plate and can move back and forth along the extending direction of the limiting grooves;

[0008] The clamp is detachably arranged on the limiting groove, and the clamping direction of the pipe by the clamp is perpendicular to the back-and-forth moving direction of the pipe cutting device;

[0009] One end of the auxiliary clamp is detachably arranged on the limiting groove, and the other end can be extended and / or height-adjusted in a direction perpendicular to the limiting groove. Through the arrangement of the clamp and the auxiliary clamp, the front and rear sides of the pipe can be quickly clamped, so that the front and rear sides of the pipe are firmly clamped, thereby facilitating the pipe cutting device to cut the pipe, and there will be no swinging of the pipe end due to loose clamping, or uneven incision.

[0010] Furthermore, the pipe cutting device includes a cutting mounting base, a rocking hand wheel, a feed module, a pipe cutting motor and an abrasive cutting disc;

[0013] The pipe cutting motor is arranged on the feed module, and the grinding wheel cutting disc is arranged at the end of the pipe cutting motor. When the hand wheel is rotated, the feed module moves in the extension direction of the limiting groove, thereby adjusting the position of the pipe cutting motor and the grinding wheel cutting disc, which is simple and convenient.

[0014] Furthermore, the feed module includes a feed connection drive shaft, a feed auxiliary shaft and a feed base;

[0015] The feed base is provided with an auxiliary guide hole and a guide hole with an internal thread, the feed connection drive shaft is provided with an external thread, the feed connection drive shaft is arranged in the guide hole of the feed base, and the feed auxiliary shaft is arranged in the auxiliary guide hole of the feed base;

[0016] The feed connection drive shaft passes through the cutting mounting base and is connected to the shaking hand wheel. When the shaking hand wheel rotates, the feed base moves back and forth on the cutting mounting base along the extension direction of the limiting groove.

[0017] The pipe cutting motor is arranged on the feed base. By controlling the rotation of the shaking hand wheel, the feed base moves along the extension direction of the limiting groove on the feed connection drive shaft, thereby moving the position of the pipe cutting motor, which is simple and convenient.

[0018] Furthermore, there are two feed auxiliary shafts, which are respectively arranged on both sides of the feed connection drive shaft. In practical applications, the number of feed auxiliary shafts can be set as needed, which is within the protection scope of the present utility model.

[0019] Furthermore, the pipe cutting motor is provided with a protective cover for protecting the grinding wheel cutting disc. The setting of the protective cover can prevent the splashing of cutting sparks and debris, and also protect the staff and other equipment.

[0020] Furthermore, the clamp includes a clamp handwheel, a rotating clamp shaft, a clamp mounting seat, a limit screw, a clamp positioning clamp block and a three-jaw chuck for clamping the front end of the pipe;

[0021] The clamper positioning block and the clamper mounting seat are respectively provided with limiting screw holes, the clamper positioning block is arranged in the limiting groove, and the clamper mounting seat is arranged on the top of the limiting groove. The limiting screw passes through the limiting screw holes on the clamper positioning block and the clamper mounting seat in sequence, and locks the clamper mounting seat in the limiting groove;

[0022] The clamp mounting seat is provided with a through hole, and the rotating clamping shaft is rotatably arranged in the through hole;

[0023] One end of the rotating clamping shaft is connected to the three-jaw chuck, and the other end is connected to the clamp handwheel. By setting the clamp positioning block in the limiting groove, when the limiting screw is tightened, the positioning of the clamp mounting seat can be achieved, and the front end of the pipe can be clamped by the three-jaw chuck, thereby facilitating the cutting of the clamped pipe.

[0024] Furthermore, the auxiliary clamp includes an auxiliary clamping support seat, an auxiliary clamping positioning block, a support positioning ring, a support positioning nut, an auxiliary support clamping arm, an auxiliary support connecting shaft, an auxiliary clamping claw and an auxiliary locking screw;

[0025] The auxiliary clamping and positioning block is arranged in the limiting groove, and a connecting thread column is provided at the bottom of the auxiliary clamping support seat. When the auxiliary clamping support seat and the auxiliary clamping and positioning block are locked with each other, the connecting thread column and the auxiliary clamping and positioning block are locked with each other;

[0030] The auxiliary locking screw is arranged on the auxiliary clamping claw to clamp the end of the pipe. Since the auxiliary clamping positioning block is arranged in the limiting groove, when the auxiliary clamping support seat is locked on the auxiliary clamping positioning block, the auxiliary clamping positioning block and the auxiliary clamping support seat are pressed on the limiting groove, thereby realizing the locking positioning of the auxiliary clamping support seat. Since the auxiliary clamping claw is sleeved on the auxiliary support clamping arm through the mounting through hole, the height of the auxiliary clamping claw can be rotated to adjust. When the height is adjusted, the auxiliary support connecting shaft connected to the auxiliary support clamping arm passes through the support positioning ring and is locked with the support positioning nut. Since a locking gear is also provided on the support positioning nut, and meshing teeth are provided on the outer side of the support positioning ring, when the auxiliary support connecting shaft and the support positioning nut are locked with each other, the support positioning nut is locked on the support positioning ring again, thereby realizing the positioning of the auxiliary clamping claw.

[0031] Furthermore, a wear-resistant pad is provided on the inner side of the auxiliary clamping claw. The provision of the wear-resistant pad can not only clamp the pipe without scratching the pipe surface, but also strengthen the clamping effect.

[0032] Furthermore, there is at least one auxiliary clamper. In practical applications, the number of auxiliary clampers can be selected as needed, which is within the protection scope of the present utility model.

[0033] Furthermore, the base plate is made of aluminum alloy material. The base plate made of aluminum alloy material can reduce weight and facilitate transportation, and is also convenient for construction in different environments.
