Description

Laser welding or cutting processes based on hydraulic lifting platforms

[0001] This application is a divisional application of the application filed on June 13, 2018, with application number 201810607395.X, entitled "Hydraulic Lifting Platform Capable of Interfacing with Laser Welding or Cutting Equipment". Technical Field

[0002] This invention belongs to the field of lifting operation technology, specifically relating to a laser welding or cutting process based on a hydraulic lifting platform. Background Technology

[0003] Currently, stationary hydraulic lifts are widely used in many industries due to their virtually unlimited stroke and strong load capacity.

[0004] However, during laser cutting, it is necessary not only to drive the cutting head to move, but also to collect the cutting debris, and the height of the cutting head also needs to be adjusted. Therefore, this application mainly combines a hydraulic lift with laser welding or cutting equipment to further enhance the practicality of the hydraulic lift. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a novel laser welding or cutting process based on a hydraulic lift.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] A laser welding or cutting process based on a hydraulic lift is disclosed. This process utilizes an integrated processing device comprising a laser welding or cutting device, a mobile trolley, and a hydraulic lift. The hydraulic lift includes a base, a support platform, a support arm, and a drive mechanism. Specifically, tracks are provided on both sides of the support platform, and a collection cavity is formed on the support platform between the two tracks. The collection cavity is funnel-shaped with a gradually decreasing diameter from top to bottom. The hydraulic lift also includes a drawer-type chip collection box connected to the bottom of the funnel. The integrated operation includes the following steps: First, the laser welding or cutting device is installed on the tracks using the mobile trolley. Simultaneously, the mobile trolley moves horizontally along the tracks, and the drive mechanism drives the support platform to rise and fall vertically to meet the horizontal and vertical movement requirements of the laser welding or cutting device. Second, the waste chips generated during laser welding or cutting fall from the funnel-shaped collection cavity into the chip collection box below. Finally, the chip collection box is pulled out to complete the collection of waste chips.

[0008] Preferably, the two tracks are symmetrically distributed and can limit the swaying of the moving trolley in the left-right and up-down directions. This facilitates installation.

[0009] According to a specific embodiment and preferred aspect of the present invention, one end of the track is open and the other end is provided with a blocking part, and the moving trolley is self-aligned and detached from the open end onto the track. This greatly facilitates the docking of laser welding or cutting equipment and elevators.

[0010] Preferably, a limiting component is also provided at the end of the track near the blocking part. When the moving trolley moves into the range monitored by the limiting component, the moving trolley stops moving forward, improving the safety control of forward movement. Specifically, the limiting component can be controlled by photoelectric sensing or by contact, both of which are conventional methods. In some specific embodiments, anti-collision and shock-absorbing washers are also provided on the blocking part. In the case of a malfunction of the limiting component, the anti-collision and shock-absorbing washers prevent the trolley from moving.

[0011] According to another specific embodiment and preferred aspect of the invention, the track includes a track frame extending laterally along the length of the support platform, an upper rail body and a lower rail body disposed on the track frame and arranged vertically and parallel to each other, and the wheels of the trolley are respectively rolled on the upper rail body and the lower rail body. Therefore, the swaying of the trolley in the left-right and up-down directions can be limited.

[0012] Preferably, the upper rail body and the lower rail body are offset left and right in the width direction of the supporting platform. The structure is simple and easy to implement.

[0013] In some specific embodiments, the longitudinal cross-section of the discharge cavity is a trapezoid that gradually decreases in size from top to bottom. This facilitates the sliding of waste chips to the bottom of the funnel. Simultaneously, the chip collection box can be pulled out of the support platform along the length of the track. Generally, any movement along the length direction requires space, and the pulling out of the drawer also requires space. This also makes the installation of the two side support arms more convenient (completely avoiding the need for the aforementioned side support arms).

[0014] In addition, the drive mechanism includes two direct-acting hydraulic cylinders located between the base and the support platform, respectively located on opposite sides near the end of the rail feed car.

[0015] Due to the implementation of the above technical solutions, the present invention has the following advantages compared with the prior art:

[0016] Existing laser welding or cutting processes are completely unrelated to hydraulic lifts, which not only limits the application of hydraulic lifts, but also makes horizontal and vertical movements during processing entirely dependent on the equipment itself. Furthermore, the equipment itself cannot collect cutting debris, among other shortcomings. This invention cleverly solves the various shortcomings of existing laser welding or cutting processes by integrating a hydraulic lift with laser welding or cutting equipment into a single integrated design. After employing laser welding or cutting processes, the laser welding or cutting equipment is installed on a track via a mobile trolley. Simultaneously, the mobile trolley moves horizontally along the track, while a drive mechanism raises and lowers the supporting platform vertically to meet the horizontal and vertical movement requirements of the laser welding or cutting equipment. Secondly, the waste chips generated during laser welding or cutting fall from a funnel-shaped collection cavity into a chip collection box below. Finally, the chip collection box is pulled out to complete the collection of waste chips. Therefore, compared with existing technologies, this invention, on the one hand, connects the lifting platform with the laser equipment, not only satisfying the horizontal and vertical movement of the laser equipment but also collecting the waste chips generated during welding or cutting, greatly facilitating the welding or cutting work of the laser equipment; on the other hand, it optimizes the function of the laser welding or cutting equipment to fully utilize the characteristics of the lifting platform for welding or cutting processes, thereby greatly enhancing the practicality of the lifting platform.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application.

[0030] Referring to Figures 1 to 5, the hydraulic lift provided in this embodiment, which can be docked with laser welding or cutting equipment, includes a base 1, a bearing platform 2, support arms 3 located on both sides of the base 1 and arranged in an inward and outward cross pattern, and a drive mechanism for driving the support arms 3 to expand or retract relative to each other. Tracks 5 are provided on both sides of the bearing platform 1, and the laser welding or cutting equipment is moved and mounted on the tracks 5 by a moving trolley. A collection cavity 20 is formed on the bearing platform 2, which is funnel-shaped with a gradually decreasing diameter from top to bottom. The hydraulic lift also includes a chip collection box 6 that is connected to the bottom of the funnel for collecting waste chips generated by the laser equipment.

[0031] In some specific embodiments, the longitudinal cross-section of the receiving cavity 20 is a trapezoidal shape that gradually decreases in size from top to bottom. This facilitates the collection of debris during welding or cutting. Specifically, the receiving cavity 20 is funnel-shaped with a gradually decreasing diameter from top to bottom on both sides of the bearing platform 2 in the length and width directions.

[0032] In this example, the drive mechanism includes two direct-acting cylinders 40 located between the base 1 and the support platform 2, respectively located on opposite sides near the end of the feed car of the track 5.

[0033] In some specific embodiments, the tracks 5 extend along the length of the support platform 2 and are symmetrically distributed on both sides of the width of the support platform 2. At the same time, one end of each track 5 is open and the other end is provided with a blocking part 7. The open end of the moving trolley is self-aligned and attached to the track 5.

[0034] In this example, track 5 includes a track frame 50 extending laterally along the length of the support platform 2, an upper rail body 51 and a lower rail body 52 mounted on the track frame 50 and arranged vertically and parallel to each other. The upper rail body 51 and the lower rail body 52 are offset laterally in the width direction of the support platform 2, and the wheels of the moving trolley are respectively mounted on the upper rail body 51 and the lower rail body 52. ​​The arrangement of the track body and the track frame limits the swaying of the moving trolley in the left-right and up-down directions, ensuring the accuracy of the laser welding or cutting equipment movement.

[0035] In some specific embodiments, a limiting component 8 is also provided at the end of the track 5 near the blocking part 7. When the moving trolley moves into the range monitored by the limiting component 8, the moving trolley stops moving forward. Specifically, the limiting component 8 can be controlled by photoelectric sensing or by contact, both of which are conventional methods. Furthermore, an anti-collision and shock-absorbing washer 9 is also provided on the blocking part 7. In the case of a malfunction of the limiting component 8, the anti-collision and shock-absorbing washer 9 prevents the movement of the trolley.

[0036] The chip collection box 6 is drawer-type and can be pulled out along the length of the track 5 to be installed outside the support platform 2. Therefore, it is very convenient for the centralized collection and treatment of waste chips.

[0037] In addition, the hydraulic lift includes support legs 1a and casters 1b connected to the base 1, and upper hooks 21 and lower hooks 11 respectively located at the bottom of the bearing platform 2 and on the side of the base 1. The support legs 1a are vertically adjustable and mounted on the base 1. The upper hooks 21 and lower hooks 11 are staggered and correspondingly located at the four corners of the base 1. When the lift is retracted, the lifting holes on the upper and lower hooks are aligned. In this way, during transportation, the two hooks of the crane can be passed through the aligned lifting holes for lifting.

[0038] In summary, the laser welding or cutting process based on a hydraulic lift in this embodiment includes the following steps:

[0039] First, the laser welding or cutting equipment is installed on the track from the open end of the track by a mobile trolley. At the same time, the mobile trolley moves horizontally along the track, and the direct-acting hydraulic cylinder drives the support platform to rise and fall vertically to meet the movement requirements of the laser welding or cutting equipment in both the horizontal and vertical directions.

[0040] Secondly, the waste chips generated during laser welding or cutting in laser welding or cutting equipment fall from the funnel-shaped receiving cavity into the chip collection box below;

[0041] Finally, pull out the waste collection box to complete the collection of waste.

[0042] As can be seen from the above, after adopting this process, the left-right and up-down movements meet the processing requirements of planar welding or cutting. Simultaneously, the space formed by the laser welding or cutting equipment, the discharge cavity, and the chip collection box facilitates the collection and gathering of waste chips during processing. Therefore, compared with existing technologies, this invention, on the one hand, connects the elevator to the laser equipment, not only satisfying the horizontal and vertical movement of the laser equipment but also collecting the waste chips generated during welding or cutting, greatly facilitating the welding or cutting work of the laser equipment; on the other hand, it optimizes the function of the laser welding or cutting equipment to fully utilize… The elevator's characteristics are utilized in welding or cutting processes, greatly enhancing its practicality. Thirdly, the two symmetrically distributed tracks, with the trolley's wheels rolling on the upper and lower rails respectively, limit its swaying in the left-right and up-down directions. Fourthly, the anti-collision and shock-absorbing pads and limiting components in the blocking section further effectively control the forward travel. Fifthly, the longitudinal cross-section of the collection chamber is a trapezoidal shape that gradually decreases in size from top to bottom, facilitating the sliding of waste chips to the bottom of the funnel. Simultaneously, the chip collection box can be pulled out along the length of the track to be mounted outside the support platform. Generally, any movement along the length requires space, and the drawer's extension also requires space, further facilitating the installation of the side support arms (completely avoiding the aforementioned side support arms).

[0043] The present invention has been described in detail above, with the aim of enabling those skilled in the art to understand and implement the invention. However, this description should not be construed as limiting the scope of protection of the invention. All equivalent changes or modifications made in accordance with the spirit and essence of the invention should be included within the scope of protection of the invention.
