Description

A mortise and tenon welded crossbeam structure for a laser cutting machine Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, and in particular to a tenon and mortise welded crossbeam structure for a laser cutting machine. Background Technology

[0002] Laser cutting equipment is an advanced processing device that uses a high-energy-density laser beam as a heat source to cut materials. During operation, the laser beam irradiates the surface of the product. When the laser beam hits the material surface, the material absorbs the laser energy, and the light energy is rapidly converted into heat energy. In a very short time, the temperature of the material surface rises sharply, reaching the melting point or even the boiling point of the material. With the development of laser cutting technology, the application of laser cutting equipment in the field of metal processing has become widespread. The laser cutting machine field is highly competitive, and the requirements for production environment and machine performance are increasing. The existing laser cutting machine beam structure can basically meet the daily use needs, but the movement speed and acceleration of the cutting machine's displacement mechanism are affected by the weight of the beam itself. On the other hand, it is difficult to ensure the rigidity of the beam by adopting a lightweight structure. Therefore, it is necessary to design a laser cutting machine beam structure with mortise and tenon joints to improve the rigidity of the beam structure, while reducing the weight to improve the movement speed and acceleration. Summary of the Invention

[0003] The purpose of this utility model is to provide a tenon and mortise welded crossbeam structure for laser cutting machines, in order to solve the problem that the existing crossbeam structure of laser cutting machines is limited by the mass of the crossbeam itself, which affects the moving speed and acceleration of the cutting machine's displacement mechanism, while adopting a lightweight structure makes it difficult to ensure the rigidity of the crossbeam.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a mortise and tenon welded crossbeam structure for a laser cutting machine, comprising a main U-shaped plate, an inner reinforcing plate, a rear side sealing plate, a rack mounting plate, a guide rail mounting plate, a transition fixing plate, mounting holes, a wire guide frame, a rear reinforcing rib, a wire routing groove, and an end face sealing plate. The main U-shaped plate has first mortises evenly spaced, with first tenons fitted into the first mortises. The first tenons are located on the inner reinforcing plate. A rear side sealing plate is welded to one side of the main U-shaped plate. A rack mounting plate is symmetrically arranged on the top of the main U-shaped plate. A guide rail mounting plate is welded to the side of the main U-shaped plate away from the rear side sealing plate. A wire guide frame is provided on the rear side sealing plate, with rear reinforcing ribs evenly spaced in the wire guide frame.

[0005] As a further technical solution of this utility model, the inner reinforcing plate is provided with a second tenon, and the second tenon is engaged with the second mortise.

[0006] As a further technical solution of this utility model, the second mortise is evenly opened on the rear side sealing plate.

[0007] As a further technical solution of this utility model, the bottom ends of the main U-shaped plate are symmetrically provided with adapter fixing plates, and the adapter fixing plates are provided with mounting holes.

[0008] As a further technical solution of this utility model, the top of the cable guide is provided with a bending plate, and the bending plate is evenly provided with cable routing grooves.

[0009] As a further technical solution of this utility model, the main U-shaped plate and the rear sealing plate are symmetrically welded with end face sealing plates at both ends, and a square hole is opened at the center of the end face sealing plate. Limiting protrusions are provided at both ends of the main U-shaped plate and the rear sealing plate.

[0010] As a further technical solution of this utility model, the end face sealing plate is symmetrically provided with limiting slots, and limiting protrusions are sleeved in the limiting slots.

[0011] This utility model provides a mortise and tenon welded crossbeam structure for a laser cutting machine. Its advantages are as follows: the main structure of the crossbeam consists of a main U-shaped plate and a rear end plate welded together. The first and second mortises on the main U-shaped plate and the rear end plate are fitted onto the first and second tenons on the inner reinforcing plate, forming a reinforced mortise and tenon connection. Symmetrically arranged transition fixing plates at the bottom of the main U-shaped plate are used for connecting and fixing the crossbeam. A rack and guide rail mounting plate are used to install the rack and guide rail. The wire guide and bending plate on the rear end plate form the drag chain guide groove of the crossbeam. The entire structure is connected by mortise and tenon joints and then reinforced by welding. The overall structure is lightweight and simple, ensuring the rigidity of the crossbeam while increasing the speed and acceleration of movement by reducing weight. Attached Figure Description
