Description

Technical Field

[0001] This utility model relates to the field of tooling table technology, and in particular to a tooling table for laser marking of liquefied gas tank covers. Background Technology

[0002] During the manufacturing process of liquefied gas tanks, protective covers for angle valves need to be installed on the tank body. The protective covers are usually shaped by cutting steel plates into a preset shape and then bending them. The shaped protective covers are then welded and fixed onto the tank body to complete the installation of the protective covers.

[0003] For example, Chinese utility model patent CN202322047607.2 discloses a laser marking fixture for liquefied gas tank covers. The fixture includes a base with two slots spaced apart, each penetrating the base, and a through slot between the two slots. Two positioning blocks are also spaced apart on the base, located on opposite sides of the two slots and each having a contoured groove. The base also includes a magnetic suction component and an ejector assembly. The magnetic suction component is located between the two slots and spaced apart from the through slot. The ejector assembly includes a rotating rod rotatably mounted on the base, with a pressing block and an ejector block at opposite ends. The pressing block is located in one of the slots, and the ejector block extends into the through slot. This utility model solves the technical problems of poor accuracy and low efficiency in manually placing steel plates, resulting in improved efficiency and accuracy in laser marking of steel plates. Furthermore, the operation of positioning and removing the steel plates is simple and easy to use.

[0004] Although the above-mentioned tooling can solve the technical problems of poor accuracy and low efficiency of manual placement of steel plates, after each steel plate is processed, the staff still need to manually pick up and load the materials. The degree of automation is not high, which reduces work efficiency and increases the labor burden of the staff. Utility Model Content

[0005] This utility model discloses a tooling table for laser marking of liquefied gas tank covers, which solves the problem that after the plates are processed, workers still need to manually pick up and load materials, resulting in a low degree of automation.

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

[0007] A tooling table for laser marking of a liquefied gas tank cover includes a worktable with a base fixed to the bottom. The worktable has two symmetrically arranged abutments and a limiting plate located between the two abutments. The worktable has two openings with the abutments located between the two openings. An electric telescopic rod that can move laterally is provided above the worktable. The telescopic end of the electric telescopic rod has an adsorption component that can pass through the opening and is used to adsorb steel plates.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] A batch of steel plates can be stacked under an opening. The electric telescopic rod can then be activated to move the adsorption assembly downwards through the opening. Once the adsorption assembly contacts the steel plate, it will hold the plate in place. The electric telescopic rod then drives the adsorption assembly to move the steel plate upwards. When the steel plate is above the worktable, the electric telescopic rod moves laterally, positioning the steel plate above the two support plates. The telescopic end of the electric telescopic rod then drives the adsorption assembly downwards, placing the steel plate on the worktable with both sides in contact with the opposite surfaces of the two support plates. After the limiting plate contacts one side of the steel plate, the adsorption assembly stops adsorbing the steel plate, completing the unloading process. The electric telescopic rod then moves laterally... The system moves to avoid obstructing the top of the steel plate. After the external laser marking machine marks the steel plate, the electric telescopic rod moves the adsorption assembly directly above the steel plate, adsorbing the finished plate and moving it upwards towards another opening. The steel plate then passes through the opening, and the adsorption stops, allowing it to fall and completing the unloading process. This process is repeated to automatically load, unload, and mark subsequent steel plates. This invention automates the loading and unloading of steel plates, eliminating the need for manual operation, improving processing efficiency, and reducing the workload of workers.

Detailed Implementation

[0014] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a tooling table for laser marking of liquefied gas tank covers, including a worktable 1. A base is fixed to the bottom of the worktable 1. Two symmetrically arranged abutments 2 are provided on the worktable 1, and a limiting plate 24 is located between the two abutments 2. Two openings 4 are formed on the worktable 1, with the abutments 2 located between the two openings 4. A laterally movable electric telescopic rod 6 is provided above the worktable 1. The telescopic end of the electric telescopic rod 6 is equipped with an adsorption component that can pass through the openings 4 and is used to adsorb steel plates. A batch of steel plates to be processed is placed under one of the openings 4 (to...). Figure 1 The position shown is located at the opening 4 on the right side of the workbench 1. Then, the telescopic end of the electric telescopic rod 6 drives the adsorption component to move downward through the opening 4. After the adsorption component contacts the steel plate, it can adsorb a steel plate. Then, the telescopic end of the electric telescopic rod 6 retracts, causing the adsorption component to move the steel plate upward through the opening 4. Then, after the electric telescopic rod 6 moves laterally, the steel plate moves to the area above the two abutment plates 2. The telescopic end of the electric telescopic rod 6 then drives the adsorption component to move downward, placing the steel plate on the workbench so that both sides of the steel plate contact the opposite surfaces of the two abutment plates 2. Then, the limiting plate 24 contacts the back of the steel plate (to...). Figure 1 (As shown in the diagram) After the steel plate is accurately placed, the adsorption component stops adsorbing the steel plate. The electric telescopic rod 6 then drives the adsorption component to move upward and then moves laterally to avoid blocking the top of the steel plate. Subsequently, the external marking machine can perform marking operations on the top surface of the steel plate. After marking is completed, the electric telescopic rod 6 drives the adsorption component to move directly above the steel plate. Then, the adsorption component moves downward to adsorb the steel plate and pulls it upward. The electric telescopic rod 6 moves towards the opening 4 on the left side of the worktable 1, so that the steel plate can be placed under the worktable 1 through the opening 4. After completing the unloading operation of the steel plate, the electric telescopic rod 6 returns to its original position, and the above operation can be repeated to continue loading the steel plate.

[0016] like Figure 1 , Figure 2 and Figure 3 As shown, the adsorption assembly includes a lifting plate 61 detachably connected to the telescopic end of the electric telescopic rod 6, and an electromagnet 62 is embedded in the bottom of the lifting plate 61; a connecting block 63 is fixed to the telescopic end of the electric telescopic rod 6, and the connecting block 63 is connected to the lifting plate 61 by bolts.

[0017] Example 1: After adjusting the magnetic force of electromagnet 62, it can just attract one steel plate without attracting another steel plate located below it. When the lifting plate 61 moves downward and contacts the steel plate, electromagnet 62 is energized, which can attract the steel plate. After electromagnet 62 is de-energized, it will no longer attract the steel plate. The battery can be installed inside the lifting plate 61 (the battery is not shown in the figure). When it is necessary to repair or replace electromagnet 62 or lifting plate 61, or when it is necessary to attract steel plates of different sizes, the bolts on the connecting block 63 can be removed and the corresponding lifting plate 61 can be replaced.

[0018] Example 2: The electromagnet 62 can be replaced with a suction cup. After setting an air pump connected to the suction cup on the lifting plate 61, the steel plate can also be attracted by the suction cup. The suction cup and the electromagnet 62 can be selected for use according to the actual situation.

[0019] like Figure 1 and Figure 3 As shown, the workbench 1 has a strip-shaped opening. A slider 21, slidably connected within the strip-shaped opening, is fixed to the bottom of the abutment plate 2. A first motor 22 is fixed to the bottom of the workbench 1, and a bidirectional lead screw 23, threadedly connected to the slider 21, is fixed to the shaft of the first motor 22. When the first motor 22 is started, causing the bidirectional lead screw 23 to rotate, the two sliders 21 can move closer together or further apart, facilitating the fixing and positioning of steel plates of different sizes. Furthermore, when a steel plate is placed on or removed from the workbench 1, the two abutments 2 can be moved further apart, preventing friction between the steel plate's sides and the opposing surfaces of the two abutments 2, which would otherwise hinder the placement and removal of the steel plate. When the steel plate contacts the top surface of the workbench 1, and the electromagnet 62 continues to attract the steel plate, the two abutments 2 move closer together, thus securing the steel plate.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, a vertical plate 3 is fixed on the workbench 1, and a first automatic telescopic rod 31 with its telescopic end connected to a limiting plate 24 is fixed on the vertical plate 3. A second motor 32 is fixed on the vertical plate 3, and a one-way lead screw 33 is fixed on the shaft of the second motor 32. A moving bar 66, which is slidably connected to the vertical plate 3, is threaded onto the one-way lead screw 33. The moving bar 66 is fixed to the fixed end of the electric telescopic rod 6. The first motor 22 and the second motor 32 are servo motors. After starting the second motor 32 to rotate the one-way lead screw 33, the electric telescopic rod 6 can drive the moving bar 66 to move laterally. The first automatic telescopic rod 31 can drive the limiting plate 24 to move forward or backward (to...). Figure 1 (as shown in the image) so that the back of steel plates of different sizes can be limited, and the two abutment plates 2 can be used to complete the precise positioning of the steel plates.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, there are two lifting plates 61, each located above one of the two openings 4; there are also two secondary motors 32, arranged in a staggered configuration. The two secondary motors 32 are configured to control the lateral movement of the two lifting plates 61. When the lifting plate 61 on the right side of the workbench 1 passes through the opening 4 (located on the right side of the workbench 1) to pick up the material and place the steel plate on the workbench 1 (the steel plate is located between the two abutment plates 2), the right-side lifting plate 61 resets and continues to pick up the steel plate to be processed. When the steel plate on the workbench 1 is finished being processed, the lifting plate 61 on the left side of the workbench 1 moves to directly above the steel plate, moves downwards to hold the top surface of the steel plate, and lifts the steel plate upwards. The lifting plate 61 then returns to its original position, allowing the processed steel plate to be unloaded through the opening 4 on the left side of the workbench 1, improving the efficiency of loading and processing subsequent steel plates.

[0022] like Figure 1 and Figure 3 As shown, a placement frame 5 is provided below the workbench 1, located below an opening 4. A second automatic telescopic rod 51, fixed to a base, is also provided below the workbench 1. The telescopic end of the second automatic telescopic rod 51 is connected to the placement frame 5. A batch of steel plates to be processed can be stacked in the placement frame 5. The placement frame 5 serves to limit the steel plates, preventing them from tilting and ensuring they are neatly arranged on the workbench 1 after being removed. Each time a steel plate is removed, the telescopic end of the second automatic telescopic rod 51 extends upwards, moving the placement frame 5 upwards and causing the steel plate to move upwards as well, facilitating the suction of the lifting plate 61. The electric telescopic rod 6 drives the lifting plate 61 to rise and fall, and in conjunction with the second automatic telescopic rod 51 driving the placement frame to rise and fall, effectively completing the removal of all steel plates.

[0023] like Figure 1 and Figure 3As shown, a No. 3 automatic telescopic rod 53 is fixed to one side of the placement frame 5. A limiting strip 54 located inside the placement frame 5 is fixed to the telescopic end of the No. 3 automatic telescopic rod 53. A vertical plate 52 is fixed inside the placement frame 5. A notch corresponding to the No. 3 automatic telescopic rod 53 is opened on the opening 4 corresponding to the placement frame 5. When placing steel plates of different sizes, the steel plates can be placed in the placement frame 5 so that one side and the back of the steel plates contact the vertical plate 52 and the inner wall of the placement frame 5 respectively (the placement frame 5 is U-shaped). Then, the telescopic end of the No. 3 automatic telescopic rod 53 drives the limiting strip 54 to approach the steel plate, which can hold the steel plate against it and limit the steel plate to prevent it from tilting. When the steel plate is attracted by the lifting plate 61, the limiting strip 54 can move slightly away from the steel plate to prevent the steel plate from rubbing against the limiting strip 54 when it is taken out.

[0024] like Figure 1 and Figure 3 As shown, a No. 4 automatic telescopic rod 7 is fixed to the base below the workbench 1. A support plate 71 is fixed to the telescopic end of the No. 4 automatic telescopic rod 7. A storage frame 8 corresponding to the opening 4 away from the placement frame 5 is placed on the support plate 71. After the processed steel plate is placed in the storage frame 8 for collection, the worker can separate the storage frame 8 from the support plate 71 to complete the transfer of the steel plate. When the steel plate is placed in the storage frame 8, the telescopic end of the No. 4 automatic telescopic rod 7 can be extended or retracted to allow the storage frame 8 to pass through the opening, facilitating the lifting plate 61 to release the steel plate. A positioning hole is opened at the bottom of the storage frame 8, and a positioning rod that matches the positioning hole is fixed on the support plate 71 (the positioning hole and positioning rod are not shown in the figure).

[0025] like Figure 1 and Figure 2 As shown, the lifting plate 61 is U-shaped. A cleaning cotton 64 is provided on the inner side of the lifting plate 61 corresponding to the placement frame 5. A cylinder 65 with its telescopic end connected to the cleaning cotton 64 is fixed on the lifting plate 61. When the lifting plate 61, located on the right side of the worktable 1, absorbs the steel plate and places it on the worktable 1, and the steel plate is restrained by the two abutment plates 2, the cylinder 65 can be activated to drive the cleaning cotton 64 to move. The cleaning cotton 64 can then clean away dust or impurities on the top surface of the steel plate, preventing any impact on subsequent marking operations on the steel plate.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
