Description

Technical Field

[0001] The invention relates to the technical field of round tube cutting, in particular to a quick-install clamp for cutting an arc opening of a round tube. Background Art

[0002] When connecting two round tubes, in order to ensure the tightness of the connection and the stability of the structure, one end of one of the round tubes usually needs to be cut into an arc. If the end of a round tube is straight and connected directly, it may be easily displaced or broken due to the small contact area when subjected to external force. Therefore, cutting the end into an arc can increase the contact area, better disperse and withstand external forces, and improve the strength of the connection.

[0003] At present, in the process of cutting the arc of a round tube, the operator is usually required to directly hold the round tube for cutting. However, this traditional method is highly dangerous because the operator is easily injured during the cutting process, and the cutting accuracy is also limited. At the same time, hand-held cutting is difficult to ensure the flatness and size consistency of the cutting surface, resulting in unstable product quality and low efficiency. In addition, due to the instability of manual operation, the scrap rate may also increase, thereby increasing production costs. Summary of the invention

[0013] Preferably, limiting grooves are provided on the front and rear surfaces of the rectangular column outside the first adjusting bolt.

[0014] Preferably, the movable plate is connected to the first adjusting bolt by threaded connection, the sliding block is connected to the second adjusting bolt by threaded connection, and the base plate is connected to the rotating bolt by threaded connection.

[0015] Preferably, the base plate is connected to the first circular shaft by a fixed connection, the rectangular column is connected to the first circular shaft by a rotational connection, and the movable plate is connected to the second circular shaft by a rotational connection.

[0016] Preferably, the threaded rod and the connecting plate are connected by threaded connection.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention fixes the round tube by means of a clamping assembly, thereby effectively avoiding the risk of injury caused by sliding of the round tube during operation and improving the safety of the operation process.

[0019] Since the clamping assembly of the present invention can ensure the stable fixation of the round tube during the cutting process, the cutting accuracy is greatly improved. Compared with manual tube holding cutting, the technical solution can achieve more accurate and smooth arc cutting, meet the needs of high-precision processing, and ensure the flatness of the cutting surface and the consistency of size.

[0020] The invention is easy to install and greatly shortens the cutting preparation time. In mass production, the fast clamping feature can significantly improve production efficiency and reduce production costs per unit time.

[0021] The invention reduces the labor intensity because the operator does not need to directly hold the round pipe for cutting, which is beneficial to the health of the operator and the improvement of the working environment.

[0022] The present invention uses a bonding tube to bond a round tube with an arc cut at one end to the surface of the bonding tube, and when the other end of the round tube is cut, the arcs at both ends can be symmetrical. BRIEF DESCRIPTION OF THE DRAWINGS
