Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a high-efficiency cutting device for a laser cutting machine. Background Technology

[0002] In the processing of materials such as sheet metal, laser cutting machines are widely used due to their high cutting precision and efficiency. Existing laser cutting machines typically use a conveyor mechanism (such as a chain or conveyor belt) to move the workpiece, working in conjunction with the laser cutting head to complete the cutting operation. However, some problems exist in practical applications. For example, molten slag generated during laser cutting can adhere to the workpiece placement structure (such as a rack). If not cleaned promptly, this can lead to uneven placement of subsequent workpieces, thus reducing cutting precision. Furthermore, existing cleaning mechanisms mostly clean in a single direction, making it difficult to completely remove stubborn molten slag.

[0003] Therefore, this application provides a high-efficiency cutting device for laser cutting machines to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a high-efficiency cutting device for laser cutting machines, which aims to solve the problem that molten slag will adhere to the workpiece placement structure (such as a toothed rack), and if it is not cleaned in time, it will lead to uneven placement of subsequent workpieces, thereby reducing the cutting accuracy.

[0005] To achieve the above objectives, this application provides the following technical solution: a high-efficiency laser cutting device, comprising a machine body, a movable laser frame, sprockets, and chains. The machine body is provided with sprockets, which are connected by chains, and the movable laser frame is mounted on the top surface of the machine body. The chains are connected by placement components, and in order to improve the stability of the chain operation, two sets of support members are provided on the inner wall of the machine body. The upper support member is slidably connected to the bottom surface of the placement component, and the lower support member is slidably connected to the chain. A reciprocating cleaning mechanism is provided below the component and is slidably connected to it; The mounting assembly also includes a mounting head and plug, a mounting rack, and a locking element. The mounting head is mounted on the chain. A mounting groove is provided on the outer wall of the mounting head, and a set of plugs is provided in the mounting groove. A through hole is provided on the mounting rack, and the through hole is adapted to the plug. A fixing hole is provided on the top surface of the mounting head, and a bolt is threaded into the fixing hole. A set of U-shaped locking elements is slidably connected to the bolt. The vertical section of the locking element is provided with a slot, and the slot is adapted to the plug.

[0006] Two sets of support members support and guide the placement component and the chain respectively. The upper support member restricts the vertical swaying of the placement component, while the lower support member reduces the lateral offset of the chain. The dual constraints reduce the workpiece position deviation during the conveying process and improve the cutting accuracy.

[0007] Preferably, the outer wall of the plug is provided with two sets of symmetrical grooves, and the slot and the grooves are adapted to each other.

[0008] Preferably, the end of the machine body is provided with a cleaning toothed plate that is slidably connected to the rack, and the cleaning toothed plate is inclined.

[0009] Preferably, the cleaning tooth plate is provided with a separation hole, and a guiding connecting rod is provided inside the separation hole.

[0010] Preferably, the reciprocating cleaning mechanism includes a placement component and a limiting component, a tray, a reciprocating rack, a reciprocating gear, a synchronous belt, and a motor. The inner wall of the machine body is provided with a tray, and the top surface of the tray is provided with a positioning component with a U-shaped cross section. The positioning component has a hole, and a limiting component with a T-shaped cross section is slidably connected in the hole. The outer end of the limiting component is provided with a placement component, and the top surface of the placement component is provided with a placement groove. The reciprocating rack is inserted into the placement groove, and the reciprocating rack is slidably connected to the placement rack. A protruding plate is provided on the top surface of the placement component, and a reciprocating rack is provided on the protruding plate. A motor slot for placing the motor is provided on the inner wall of the machine body. Two sets of symmetrical reciprocating gears are rotatably connected in the motor slot. Coaxial synchronous pulleys are provided on the reciprocating gears. The two sets of synchronous pulleys are connected by a synchronous belt. One set of synchronous pulleys is driven by a motor. The reciprocating gear is a half gear.

[0011] In summary, the technical effects and advantages of this utility model are as follows: This invention combines the initial cleaning of the cleaning toothed plate with the deep cleaning of the reciprocating cleaning mechanism to achieve a dual cleaning effect of "initial peeling during dynamic conveying and reciprocating wiping after flipping". The inclined design of the cleaning toothed plate causes more than 80% of large molten slag particles to slide off with gravity, and the reciprocating cleaning mechanism, driven by a half-gear, improves the removal rate of fine molten slag residue between the teeth of the rack to more than 95%.

[0012] This utility model features a quick-release structure with a "plug-slot" locking mechanism for the placement component. Initial positioning of the rack can be completed without tools. The linkage between the bolt and the locking mechanism enables quick locking / unlocking, reducing assembly and disassembly time by 60% compared to traditional bolt fixing methods. The reciprocating toothed plate of the reciprocating cleaning mechanism adopts a plug-in design, allowing for direct pull-out replacement, significantly reducing maintenance costs.

[0013] In this invention, the separation hole of the cleaning toothed plate cooperates with the connecting rod to prevent slag from accumulating on the toothed plate; the reciprocating cleaning mechanism is linked with the motor through a synchronous belt to ensure that the cleaning action is synchronized with the chain conveying rhythm; the matching design of the plug groove and the locking slot increases the connection strength of the toothed plate by 40% and prevents structural loosening caused by vibration during cutting.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Reference Figure 1-6 The high-efficiency laser cutting device shown includes a machine body 1, a movable laser frame 2, sprockets 3, chains 4, and a placement assembly 5. The movable laser frame 2 (which can move along the X / Y / Z axes) is provided on the top surface of the machine body 1. Two sets of sprockets 3 are rotatably connected to the inner wall of the machine body 1 through bearings. The chains 4 mesh between the sprockets 3 and are driven by a drive motor built into the machine body 1. The chain 4 is spaced apart and the components 5 are installed on it. Two sets of symmetrical support members are welded to the inner wall of the body 1: the upper support member is a strip-shaped slider (with a rectangular cross section) that is slidably connected to the groove on the bottom surface of the component 5; the lower support member is slidably connected to the chain link on the outside of the chain 4, and the swaying of the chain 4 is reduced by sliding friction.

[0019] As one implementation method in this embodiment, the mounting head 6 is fixed to the link of the chain 4 by bolts. The outer wall of the mounting head 6 has a mounting groove 600. The inner wall of the mounting groove 600 is welded with a plug 7. The outer wall of the plug 7 has symmetrically formed V-shaped grooves. Through holes are made at both ends of the rack 8, and the through holes are fitted with the plug 7 with clearance. Fixing holes 601 are made on the top surface of the mounting head 6, and bolts are connected by internal threads in the fixing holes 601. U-shaped locking parts 9 are fitted on the bolts. Slots 900 are made on the inner side of the vertical section of the locking parts 9. Slots 900 fit with the grooves of the plug 7. Tightening the bolts can drive the locking parts 9 to move down, so that the slots 900 are engaged in the grooves of the plug 7, thereby locking the rack 8.

[0020] In one embodiment of this invention, a cleaning toothed plate 10 (tilted at an angle of 30°) is bolted to the discharge end of the machine body 1. The tooth pitch of the cleaning toothed plate 10 is adapted to the placement of the rack 8, and the tooth tips are coated with a wear-resistant coating. The cleaning toothed plate 10 has a separation hole 100, and a connecting rod is inserted into the separation hole 100 to guide the molten slag to fall into the waste hopper below.

[0021] As one embodiment of this example, the reciprocating cleaning mechanism 11 has a tray 15 welded to the inner wall of the body 1, a U-shaped positioning member 14 welded to the top surface of the tray 15, a hole opened on the outer wall of the positioning member 14, a T-shaped limiting member 13 slidably connected in the hole, a placement member 12 welded to the outer end of the limiting member 13, a placement groove 1200 opened on the top surface of the placement member 12, and a reciprocating toothed plate (matching the tooth pitch of the placement rack 8) inserted into the placement groove 1200. A protruding plate 1201 is welded to the top surface of the placement component 12, and a reciprocating rack 16 is welded to the side of the protruding plate 1201. A motor slot is opened in the inner wall of the machine body 1, and a motor 19 is built in. The output shaft of the motor 19 is connected to a reciprocating gear 17. Another reciprocating gear 17 is symmetrically arranged on the same side. The two gears are linked with the synchronous belt 18 through a synchronous pulley. When the reciprocating gear 17 meshes with the reciprocating rack 16, it drives the placement component 12 to move back and forth.

[0022] The working principle of this utility model is as follows: By placing the sheet metal on the placement assembly 5, and then starting the machine body 1 and the moving laser frame 2, the laser cutting device on the moving laser frame 2 can be controlled to move forward, backward, left, right, up, and down. The drive device inside the machine body 1 controls the sprocket 3 to rotate, which in turn drives the chain 4 to work. Since the slag produced after laser cutting will fall onto the placement rack 8, in order to avoid the sheet metal on the placement rack 8 not being able to be on a flat plane due to the accumulation of slag, a cleaning toothed plate 10 is provided at the end of the machine body 1. Driven by the chain 4, the placement rack 8 can contact the cleaning toothed plate 10 when it is flipped, thereby cleaning the placement rack 8 locally. During this process, the waste material and finished parts of the sheet metal slide down the cleaning toothed plate 10 to the next process, and the slag and smaller waste materials slide down from the separation hole 100 and are collected in the waste collection hopper below. After being rotated 180 degrees, the placement component 5 comes into contact with the reciprocating cleaning mechanism 11. Upon initial contact, longitudinal cleaning is performed only by the reciprocating toothed plate to remove the attached slag from the top of the placement rack 8. After several rotations, the placement rack 8 and the reciprocating toothed plate are misaligned. The motor 19 in the motor slot is activated, and the motor drives the synchronous pulley to rotate. The synchronous pulley drives the reciprocating gear 17 to rotate in the motor slot via the synchronous belt 18. Since the reciprocating gear 17 is a half gear, it can drive the reciprocating rack 16 to reciprocate. This, in turn, drives the placement component 12 to slide on the support plate 15 via the convex plate 1201. The design of the positioning component 14 and the limiting component 13 provides limiting protection. During the reciprocating process, the reciprocating toothed plate cleans the placement rack 8 laterally.

[0023] When it is necessary to replace the reciprocating gear plate, simply pull it upwards to separate the reciprocating gear plate from the placement slot 1200.

[0024] When maintenance is required on the placement component 5, unscrew the bolts to separate it from the fixing hole 601, then remove the locking piece 9, separating the slot 900 of the locking piece 9 from the groove on the plug 7. Then pull the placement rack 8 outward to separate the placement rack 8 from the mounting slot 600 and the plug 7, thus completing the removal of the placement rack 8. After replacing it, the operation is reversed to complete the replacement.

[0025] Mounting head 6 is fixedly mounted on chain 4.
