Description

TECHNICAL FIELD

[0001] The utility model relates to laser processing technical field, especially a kind of beam sliding structure of laser cutting equipment. BACKGROUND

[0002] In modern industrial manufacturing field, laser cutting technology has become the key process means indispensable to many industries such as metal processing and plate manufacturing with its high precision, high speed and excellent cutting quality and many other advantages. As the core carrier of the technology, the performance and structure design of each component of the laser cutting equipment play a decisive role in the overall operation effect and processing precision of the equipment, and the beam sliding structure is a very important link.

[0003] The conventional beam sliding structure of laser cutting equipment usually sets a driving motor on the support, sets a gear on the output end of the driving motor, and forms a transmission by cooperating the gear with the rack on the rack. The beam is driven to reciprocate along the rack guide, and then the cutting head realizes accurate operation at different positions. However, this kind of conventional design has significant disadvantages. The past motor is usually installed on one side of the support, for example, close to the front side of the beam, so that the power transmission is uneven. Under the actual operation of the equipment and the frequent forward and backward sliding of the beam, due to the unreasonable position of the driving motor, eccentric force is easily generated in the power transmission process. This not only causes the equipment to vibrate violently during operation, greatly affects the cutting precision, makes the edges of the cut workpieces have sawtooth, burr and other defects, reduces the product quality, but also intensifies the wear between the components of the equipment, greatly reduces the service life of the equipment, increases the maintenance cost and frequency.

[0004] In addition, due to uneven stress, the stability of the beam moving forward and backward is obviously different. When cutting complex patterns and frequently switching moving direction, this instability is more prominent, which causes the cutting head to be misaligned and difficult to meet the high-precision processing requirements. Moreover, the vibration and imbalance problem also affects the running speed of the equipment.

DETAILED DESCRIPTION

[0023] The utility model provides a kind of beam sliding structure of laser cutting equipment, to make the purpose, technical scheme and effect of the utility model more clear, definite, the following referring to drawing and taking example to the utility model further detailed explanation.It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the protection scope of the utility model.

[0024] Please refer to Figures 1 to 4 The utility model provides a kind of beam sliding structure of laser cutting equipment, including square beam 1 and the first support 2 and second support 3 respectively being arranged in square beam 1 left and right two ends, first motor 4 being arranged on first support 2, second motor 5 being arranged on second support 3, first gear 41 being arranged on the output end of first motor 4, and second gear 51 being arranged on the output end of second motor 5;The first support 2 includes two first wing plates 21 from the left end side of square beam 1 stretches out, the first flat seat plate 22 being connected with the bottom of first wing plate 21, the bottom surface of first flat seat plate 22 is provided with first sliding block 61 at the inner side of first gear 41, under left projection, first motor 4 is arranged on first flat seat plate 22 and is located between two first wing plates 21, the axis of first motor 4 coincides with the vertical central axis of square beam 1, the vertical central axis of square beam 1 is perpendicular to the first sliding block 61;The second support 3 includes two second wing plates 31 from the right end side of square beam 1 stretches out, the second flat seat plate 32 being connected with the bottom of second wing plate 31, the bottom surface of second flat seat plate 32 is provided with second sliding block 62 at the inner side of second gear 51, under right projection, second motor 5 is arranged on second flat seat plate 32 and is located between two second wing plates 31, the axis of second motor 5 coincides with the vertical central axis of square beam 1, the vertical central axis of square beam 1 is perpendicular to the second sliding block 62.

[0025] When working, see Figure 5As shown, the first motor 4 and the second motor 5 are synchronously operated, and each outputs torque to drive the first gear 41 and the second gear 51. Since the first motor 4 is arranged downward on the first flat base plate 22 in the left projection, and is located between the two first wing plates 21, the axis of the first motor 4 coincides with the vertical central axis of the square beam 1. Similarly, the layout of the second motor 5 in the right projection also follows this rule. This layout makes the power output uniform and symmetrical. When the gears rotate, they rely on the meshing relationship with the corresponding rack 74 on the frame to push the beam to reciprocate along the guide rail of the frame, thereby accurately controlling the position of the cutting head and achieving cutting operation. At the same time, the first flat base plate 22 of the first support 2 is provided with a first sliding block 61, and the second flat base plate 32 of the second support 3 is provided with a second sliding block 62. The sliding blocks cooperate with the guide rails to assist the beam to slide stably, ensure smooth movement, and the vertical central axis of the square beam 1 is vertically divided into the sliding blocks, which further ensures that the sliding blocks are uniformly stressed when bearing the weight of the beam and transmitting the driving force of the motor. Under this symmetrical and uniform design, the sliding blocks on both sides can equally share the force from the beam and the running force, so that the overall stress of the sliding blocks is in a balanced state, greatly prolonging the service life of the sliding blocks and reducing the equipment downtime for maintenance caused by sliding block damage.

[0026] The beam sliding structure provided by the utility model forms a bilateral motor symmetrical layout by symmetrically arranging the first motor 4 and the second motor 5 on the left and right end supports of the square beam 1 respectively, and the motor axis coincides with the vertical central axis of the beam, effectively solving the problem of uneven stress caused by the installation of the motor to one side in the traditional design. This layout eliminates eccentric force from the power source, and the gears are uniformly stressed during meshing and transmission with the rack 74, so that the beam can maintain a high degree of stability during the entire reciprocating sliding stroke and will not appear stage shaking and deviation due to uneven stress, greatly improving the continuity and stability of the sliding operation, ensuring accurate positioning of the cutting head, and being beneficial to processing workpieces with complex shapes and high precision requirements.

[0027] See Figure 1 As shown, the first wing plate 21 is located between the two first wing plates 21 and forms a first transmission area 23 with the first flat base plate 22. The first wing plate 21 is away from the first motor 4 and forms two mutually symmetrical first structural stable areas 24 with the first flat base plate 22. The first flat base plate 22 and the first wing plate 21 are connected by the first triangular plate 25 at the intersection in the first structural stable area 24. The triangular plate 25 cleverly utilizes the stability principle of the triangular structure to greatly enhance the rigidity of the local and even the whole support. When the beam frequently slides and the equipment is in a long-time vibration working condition, the triangular plate can effectively disperse and bear the stress from all directions, and can prevent the first wing plate 21 and the first flat base plate 22 from cracking, bending and other deformation phenomena, thereby stabilizing the support structure and providing a solid foundation for the stable operation of the beam.

[0028] The design of two symmetrical first structural stabilization zones 24 ensures balanced force distribution on both sides of the first support 2. When bearing the weight of the beam itself, the additional weight of the cutting head, and the inertial force during movement, the symmetrical structure on both sides can work together to provide support, preventing imbalance caused by excessive load on one side, eliminating support distortion, and maintaining the horizontal and stable posture of the beam in all directions, meeting the stringent requirements of high-precision cutting for equipment structural stability.

[0029] Further, see Figure 3 and Figure 4 As shown, a third slider 63 is provided on the bottom surface of the first flat plate 22 below the two first structural stabilization zones 24. The first slider 61 and the two third sliders 63 are arranged in the same row to form a multi-point support system. During the sliding of the crossbeam along the frame guide rail, they share the weight of the crossbeam and the components above, effectively dispersing the pressure and avoiding uneven wear of the sliders or local deformation of the guide rail due to excessive load on a single point. Compared with relying on a single slider for support, this layout makes the crossbeam more evenly stressed in the horizontal direction, significantly reducing the risk of swaying and displacement caused by uneven stress, ensuring the smooth and linear sliding of the crossbeam, and improving the positioning accuracy of the cutting operation.

[0030] Similarly, see Figure 2 As shown, the area enclosed between the two second wing plates 31 and the second flat seat plate 32 is the second transmission zone 33. The area enclosed by the second wing plates 31 and the second flat seat plate 32, which are opposite to the second motor 5, are two symmetrical second structural stabilization zones 34. The second flat seat plate 32 and the second wing plates 31 are reinforcedly connected at the junction of the second structural stabilization zones 34 by a second triangular plate. This reinforced connection between the second flat seat plate 32 and the second wing plates 31 at the junction of the second structural stabilization zones 34 cleverly utilizes the stability principle of a triangular structure, significantly enhancing the rigidity of the support, both locally and overall. When the beam frequently slips or the equipment is under prolonged vibration, the second triangular plate can effectively disperse and bear stress from all directions, preventing cracking, bending, and other deformations between the second wing plates 31 and the second flat seat plate 32, thus stabilizing the support structure and providing a solid foundation for the smooth operation of the beam.

[0031] The design of two symmetrical second structural stabilization zones 34 ensures balanced force distribution on both sides of the second support 3. When bearing the weight of the crossbeam, the additional weight of the cutting head, and the inertial force during movement, the symmetrical structure on both sides can work together to provide support, preventing imbalance caused by excessive load on one side, eliminating support distortion, and maintaining the horizontal and stable posture of the crossbeam in all directions, meeting the stringent requirements of high-precision cutting for the structural stability of the equipment.

[0032] Similarly, see Figure 3As shown, the bottom surface of the second flat base plate 32 is provided with fourth sliding blocks 64 below the two second structural stable regions 34, and the second sliding blocks 62 are arranged in line with the two fourth sliding blocks 64, forming a multi-point support system, which can jointly bear the weight of the cross beam and the components above during the sliding of the cross beam along the rack guide rail, effectively dispersing the pressure and avoiding uneven wear of the sliding blocks or local deformation of the guide rail due to excessive load on a single point. Compared with relying on a single sliding block for support, this layout makes the cross beam more balanced in the horizontal direction, significantly reducing the risk of shaking and deviation caused by uneven stress, ensuring smooth and linear sliding of the cross beam, and improving the positioning accuracy of the cutting operation.

[0033] As shown in Figure 1 and Figure 2 As shown, the top surface of the square cross beam 1 is provided with a first guide rail 71 and a second guide rail 72 extending in the transverse direction and arranged in parallel with each other, and a third guide rail 73 extending in the transverse direction is arranged on the front end surface of the square cross beam 1. The top surface of the square cross beam 1 is provided with a rack 74 extending in the transverse direction between the first guide rail 71 and the second guide rail 72. The sliding table carrying the vertical beam cutting structure is connected to the first guide rail 71, the second guide rail 72 and the third guide rail 73 through sliding blocks, respectively. It can be understood that after observing the first guide rail 71, the second guide rail 72 and the third guide rail 73 form a triangular layout in the longitudinal section of the square cross beam 1, the square cross beam 1 is endowed with excellent stability. During the operation of the laser cutting equipment, the cross beam not only bears its own weight, but also bears the weight of the cutting head and related auxiliary equipment, and bears various dynamic forces generated during cutting, such as cutting force, inertia force generated by acceleration, etc. The triangular guide rail layout can efficiently disperse these forces, avoid stress concentration, prevent the cross beam from twisting and deforming, and maintain a stable structure at all times, laying a solid foundation for high-precision cutting operations.

[0034] Preferably, as shown in Figure 3 As shown, the bottom surface and the back surface of the square cross beam 1 are provided with hollow openings 11. Under the premise that the basic strength and rigidity of the cross beam meet the operation requirements of the laser cutting equipment, the hollow openings 11 can remove part of the redundant material. This directly reduces the weight of the cross beam, reduces the overall load of the equipment, and helps to reduce the energy consumption of the driving motor and improve energy utilization efficiency for some laser cutting equipment that needs to be frequently moved and adjusted.

[0035] Further, as shown in Figure 3As shown, the square beam 1 is internally provided with a plurality of internally fixed plates 12 arranged in the transverse direction. When the light cutting device is running, the beam needs to bear the heavy pressure from the cutting head, the cutting force in the cutting process, and the inertia force caused by the start and stop of the device, and other complex external forces. The internally fixed plates 12 are arranged in the transverse direction, like building a row of load-bearing walls inside the beam, effectively dispersing stress and avoiding stress concentration in local areas. When external force is applied, these internally fixed plates 12 work together to uniformly conduct and disperse the force to the entire beam structure, greatly enhancing the beam's ability to resist deformation, allowing it to maintain a stable state at all times under long-term, high-strength working conditions, and ensuring cutting precision is not disturbed by structural deformation.
