Description

Technical Field

[0001] This invention belongs to the field of large-format laser cutting machine manufacturing technology, and particularly relates to a large-format split-type laser cutting machine bed connection structure and assembly method. Background Technology

[0002] Laser cutting involves focusing a laser beam emitted from a laser source into a high-power-density beam via an optical path system. This beam irradiates the workpiece surface, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas, coaxial with the beam, blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thus achieving the purpose of cutting.

[0003] Large-format laser cutting machines are becoming increasingly widely used, mainly for cutting large plates or processing large equipment. The bed of a large-format laser cutting machine is longer, which makes manufacturing more difficult. Traditionally, the bed of a large-format laser cutting machine is extended by connecting two sets of beds with bolts. However, the bolted bed has gaps between the threads and causes significant vibration during laser cutting, which affects the processing and reduces the laser cutting accuracy. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of traditional large-format laser cutting machine bed extension, which involves connecting two sets of beds with bolts. However, bolted beds have gaps between the threads and cause significant vibration during laser cutting, which affects processing and reduces laser cutting accuracy. Therefore, this invention provides a large-format split laser cutting machine bed connection structure and assembly method.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A large-format split-type laser cutting machine bed connection structure includes a movable crossbeam, with a laser cutting machine bed located below both ends of the movable crossbeam. The laser cutting machine bed includes a first bed, a second bed at one end of the first bed, and connecting plates on both sides of the adjacent ends of the first and second beds. First pin grooves are provided on both sides of the joint of the connecting plates, with first keyes inside the first pin grooves. Second pin grooves are provided on the adjacent upper surfaces of the first and second beds, with second keyes inside the second pin grooves. A guide post is provided on the end face of the second bed, and a guide hole is provided on the first bed at the corresponding position of the guide post. A screw is provided below the guide post, and an insertion hole is provided on the first bed at the corresponding position of the screw. A fixing frame is provided in the insertion hole, and a nut is provided inside the fixing frame. The nut is connected to the fixing frame via a bearing. An adjustment port is provided on one side of the first bed at the corresponding position of the nut.

[0007] Furthermore, the connecting plate is welded to both the first and second beds, and both are equipped with reinforcing ribs.

[0008] Furthermore, a dividing groove is provided between the two end faces of the first and second pins.

[0009] Furthermore, both the guide post and the guide hole are tapered.

[0010] Furthermore, both the first and second pins have right-angled bevels at each end.

[0011] An assembly method for a large-format split-type laser cutting machine bed connection structure includes the following steps:

[0012] Step 1: Align the two ends of the first and second beds with the connecting plates;

[0013] Step 2: Insert the screw into the socket until the nut is in position, then insert the guide post into the guide hole;

[0014] Step 3: Use a wrench to turn the nut through the adjustment port. The screw and nut engage, bringing the second bed closer to the first bed. At the same time, the guide post engages with the guide hole to provide guidance.

[0015] Step 4: After the first bed and the second bed come into contact, connect the connecting plate with several bolts;

[0016] Step 5: After connecting the connecting plates with bolts, grind the dimensions on both sides of the first and second pin key dividing grooves, and then embed them into the first and second pin grooves respectively to make them fit tightly.

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

[0018] (1) The bed is moved by the cooperation of nuts and screws, which is safer and more stable and saves manpower.

[0019] (2) The fit between the guide column and the guide hole can accurately position the connection between the two beds, reduce fit error and improve fit accuracy.

[0020] (3) The first key and the second key are adjusted in size by grinding so that the key and the slot fit tightly together, which can limit the position of the two bed, prevent the machining vibration from affecting the bed, and improve the machining accuracy. Attached Figure Description
