Description

Technical Field

[0001] The invention relates to the technical field of liquid level control box shell processing, in particular to a liquid level control box shell forming device and an assembling process. Background Art

[0002] The liquid level control box shell is a shell device used to accommodate relevant components of the liquid level control system (such as liquid level sensors, controllers, relays, etc.). It mainly plays the role of protecting internal components, dustproof, waterproof and supporting installation. It is widely used in industrial scenarios such as water treatment, chemical industry, food, etc. that need to monitor and control the liquid level. The shell of the liquid level control box is formed by sheet metal stamping, bending and other processes to make a shell with specific size and protective structure. Assembly is to combine the various shell components to form a complete shell.

[0003] However, the prior art still has the following problems:

[0004] The existing liquid level control box shell molding device and assembly process mostly have poor assembly accuracy. The existing molding device parts have low matching accuracy and lack of precision guide structure. Deviations are prone to occur in the mold closing process, resulting in large position errors of various components when assembling the liquid level control box shell. It is difficult to meet high-precision production requirements and the defective rate remains high.

[0005] Secondly, production efficiency is usually low. Traditional assembly process equipment has a single function. Multiple devices are required to complete clamping, forming, bending, welding and other processes. Frequent equipment replacement and workpiece transfer are time-consuming and labor-intensive, the production cycle is long, and the equipment responds slowly, making it difficult to achieve fast and continuous operations, which seriously restricts the improvement of production efficiency.

[0006] In addition, some devices are complex to operate and have low safety. Existing molding devices mostly rely on manual operation, parameter adjustment is cumbersome, the degree of automation is low, workers have high operating intensity and are prone to errors. At the same time, the equipment protection design is imperfect and the operating stability is poor. There are safety hazards such as loose parts and mechanical injuries during operation, which cannot fully guarantee the safety of operators.

[0007] In response to the above problems, the inventors proposed a liquid level control box shell molding device and assembly process to solve the above problems. Summary of the Invention

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example: Figure 1-8 As shown, the present invention provides an assembly process for a liquid level control box housing, comprising the following steps:

[0035] S1. Place the lower mold on the upper surface of the clamping frame and start the first motor. The first motor drives the bidirectional lead screw to rotate, causing the two side clamps to move toward each other along the positioning columns. The sliders slide together on the lower side of the clamping frame to firmly clamp the lower mold. At the same time, start the first cylinder, which pushes the lifting plate downward to close the upper mold plate and the lower mold, completing the preliminary molding preparation of the shell component.

[0036] S2. Place the sheet to be bent on the bending plate, so that one side of the sheet is against the plate, and start the second cylinder. The second cylinder pushes the cross plate downward, and the cross plate drives the bending block to follow the guide of the plug column and the sleeve, pressing the sheet into the bending groove to complete the bending operation of the sheet;

[0037] S3. Drive the threaded column to rotate through the second motor, so that the moving block moves along the axial direction of the threaded column, drive the moving plate to move on the transplanting plate, and use the first electric push rod to adjust the height of the welding gun; place the shell component that has been preliminarily formed and bent on the L-shaped plate, start the second electric push rod, so that the clamping plate clamps and fixes the component, and then control the welding gun to move to the welding position, perform precise welding on the shell component, and complete the assembly of the liquid level control box shell.

[0038] The present invention also provides a forming device for the assembly process of the liquid level control box shell, including a base plate 1, a carrier plate 3, a bending plate 4, a transfer plate 5 and an L-shaped plate 7 are fixedly provided on the upper surface of the base plate 1, a welding gun 56 is provided on the upper side of the transfer plate 5, and the welding gun 56 is located on one side of the upper surface of the L-shaped plate 7, an upper plate 2 is fixed on the upper side of the carrier plate 3, a lower mold 37 is provided on the upper surface of the carrier plate 3, a clamping frame 36 is embedded on the upper surface of the carrier plate 3, a support rod 21 is symmetrically fixed on the upper surface of the base plate 1, and the upper surface of the support rod 21 is fixed with the upper plate 2, the base plate 1 serves as the basic supporting structure of the entire forming device, and provides an installation platform for components such as the carrier plate 3, the bending plate 4, the transfer plate 5 and the L-shaped plate 7, the carrier plate 3 is used to carry the lower mold 37, the upper plate 2 is fixed on the base plate 1 by the support rod 21, and provides an installation position for components such as the first cylinder 22, and the various components cooperate with each other to form the basic structure of the forming device, ensuring that the relative positions of the various components are stable during operation.

[0039] A first cylinder 22 is fixedly provided on the upper surface of the upper plate 2, and the output end of the first cylinder 22 passes through the upper plate 2 and is fixed with a lifting plate 23. The lower surface of the lifting plate 23 is symmetrically and detachably provided with an upper mold plate 24. The upper surface of the lifting plate 23 is symmetrically fixed with columns 25, and the upper ends of the columns 25 pass through the upper plate 2. When the first cylinder 22 is working, the lifting plate 23 is driven by the telescopic movement of the output end to perform vertical lifting movement under the guidance of the columns 25. The columns 25 pass through the upper plate 2, which plays a role in limiting the movement direction of the lifting plate 23, ensuring that the lifting plate 23 can only move in the vertical direction, so that the upper mold plate 24 can accurately perform mold closing and opening actions with the lower mold 37.

[0040] A sleeve block 26 is symmetrically fixed on the upper surface of the lifting plate 23, and an insert block 27 is fixed on the outer side of the upper mold plate 24, and the insert block 27 is inserted into the corresponding sleeve block 26. The sleeve block 26 and the insert block 27 are connected by bolts. The insert block 27 is inserted into the sleeve block 26 to form a preliminary positioning, and then fastened with bolts to achieve a detachable connection between the upper mold plate 24 and the lifting plate 23. This connection method facilitates the rapid disassembly and replacement of the upper mold plate 24 when the mold is worn or when it is necessary to produce shells of different specifications, thereby improving the versatility and maintenance convenience of the equipment.

[0041] The lower surface of the lower mold 37 is movably fitted with the upper surface of the clamping frame 36, and a bidirectional lead screw 31 is rotatably provided in the clamping frame 36. A first motor 32 is fixedly provided on one side of the clamping frame 36, and the output end of the first motor 32 passes through the clamping frame 36 and is fixedly connected to the bidirectional lead screw 31. A clamping block 33 is symmetrically threaded on the outer surface of the bidirectional lead screw 31, and the inner side of the clamping block 33 is movably fitted with the lower mold 37. After the first motor 32 is started, it drives the bidirectional lead screw 31 to rotate. Since the two sections of thread on the bidirectional lead screw 31 have opposite rotation directions, the clamping blocks 33 symmetrically arranged thereon will move toward or away from each other along the positioning column 34 under the action of thread transmission. When the clamping block 33 moves toward each other, its inner side contacts and applies pressure with the lower mold 37, firmly clamping the lower mold 37 on the clamping frame 36, ensuring that the position of the lower mold 37 is fixed during subsequent processing to prevent displacement.

[0042] A slider 35 is fixed to the lower surface of the clamping block 33, and the slider 35 is clamped on the lower side of the clamping frame 36. A positioning column 34 is fixed in the clamping frame 36, and the positioning column 34 passes through the clamping block 33. The positioning column 34 passes through the clamping block 33 to provide a guide for the movement of the clamping block 33, limiting the movement of the clamping block 33 only along the axial direction of the bidirectional screw 31, avoiding the clamping block 33 from offsetting or rotating during the movement. The slider 35 is clamped on the lower side of the clamping frame 36, further enhancing the stability of the clamping block 33 during movement, and at the same time sharing the pressure on the clamping block 33 when clamping the lower mold 37, making the movement of the clamping block 33 smoother and the clamping effect more reliable.

[0043] A stop plate 41 is fixed to one side of the upper surface of the bending plate 4, an upper bracket 42 is fixed to the upper side of the bending plate 4, the upper bracket 42 is fixedly connected to the bottom plate 1, and a reinforcing rod 43 is fixedly connected between the upper bracket 42 and the upper plate 2, a second cylinder 44 is fixed to the lower surface of the upper bracket 42, and a transverse plate 45 is fixedly connected to the output end of the second cylinder 44, a bending pressure block 46 is fixed to the lower surface of the transverse plate 45, a bending groove 47 for use with the bending pressure block 46 is opened on one side of the upper surface of the bending plate 4, sleeves 48 are symmetrically fixed on both sides of the transverse plate 45, and a plug is fixed on the upper bracket 42 49, and the plug post 49 is inserted in the corresponding sleeve 48. When the second cylinder 44 is working, its output end pushes the cross plate 45 to move downward, and the cross plate 45 drives the bending pressure block 46 to move downward along the guide of the plug post 49 and the sleeve 48. When the bending pressure block 46 contacts the plate placed on the bending plate 4, the plate is pressed into the bending groove 47, and the other side of the plate is abutted and limited by the abutment plate 41 to realize the bending operation of the plate. The reinforcing rod 43 enhances the connection strength between the upper bracket 42 and the upper plate 2, ensuring the stability of the entire structure during the bending process and preventing deformation due to force.

[0044] The upper surface of the transplanting plate 5 is symmetrically fixed with support blocks 51, and a threaded column 59 is rotatably provided between the two support blocks 51, wherein a second motor 52 is fixed to the outer side of one of the support blocks 51, and the output end of the second motor 52 passes through the support block 51 and is fixedly connected to the threaded column 59, and a moving block 53 is threadedly sleeved on the outer surface of the threaded column 59, and a moving plate 54 is fixedly provided on the upper surface of the moving block 53, and a first electric push rod 8 is fixed on the upper surface of the moving plate 54, and a support member 55 is fixed on the upper surface of the first electric push rod 8. One side of the support member 55 is fixedly connected to the welding gun 56, and the second motor 52 drives the threaded column 59 to rotate, and the threaded column 59 causes the moving block 53 to move along the axial direction of the threaded column 59 through threaded transmission, thereby driving the moving plate 54 to move on the transplanting plate 5, and the first electric push rod 8 can adjust the height position of the support member 55 and the welding gun 56 through telescopic movement, thereby realizing the position adjustment of the welding gun 56 in the horizontal and vertical directions to meet the welding requirements of different positions and realize precise welding of the shell components.

[0045] The upper surface of the transplanting plate 5 is symmetrically fixed with a guide rail 57, and the upper surface of the guide rail 57 is slidably provided with a guide block 58. The upper surface of the guide block 58 is fixedly connected to the movable plate 54. The guide rail 57 cooperates with the guide block 58 to provide guidance and support for the movement of the movable plate 54. When the movable block 53 drives the movable plate 54 to move, the guide block 58 slides on the guide rail 57 to ensure that the movable plate 54 moves smoothly in a straight line direction, prevents the movable plate 54 from shaking or deflecting during the movement, improves the accuracy and stability of the movement of the welding gun 56, and ensures the welding quality.

[0046] A support 71 is symmetrically fixed between the L-shaped plate 7 and the base plate 1, a vertical block 72 is symmetrically fixed on the upper surface of the base plate 1, and a second electric push rod 73 is fixed on one side of the vertical block 72, and the output end of the second electric push rod 73 is fixedly connected to a clamping plate 74, and the clamping plate 74 is located on one side of the L-shaped plate 7. The support 71 enhances the connection strength between the L-shaped plate 7 and the base plate 1, ensuring the stability of the L-shaped plate 7 during operation. When the component needs to be clamped and fixed, the second electric push rod 73 pushes the clamping plate 74 to move to one side of the L-shaped plate 7 through the telescopic movement of the output end, clamping the component between the clamping plate 74 and the L-shaped plate 7, providing a stable fixed support for subsequent processing operations, ensuring that the component will not be displaced during the processing.

[0047] Working Principle: During the assembly process of the liquid level control box housing, the various components of the molding device work together. First, the lower mold 37 is placed on the clamping frame 36. The first motor 32 is started, which drives the bidirectional screw 31 to rotate, causing the two side clamps 33 to move toward each other along the positioning columns 34. The slider 35 slides on the lower side of the clamping frame 36 to firmly clamp the lower mold 37.

[0048] Subsequently, the first cylinder 22 works, and its output end pushes the lifting plate 23 downward. The upper mold plate 24, through the cooperation of the insert block 27 and the sleeve block 26, moves downward with the lifting plate 23 and closes the mold with the lower mold 37 to achieve the initial molding of the shell component.

[0049] During the bending process, the second cylinder 44 drives the horizontal plate 45 to descend, and the bending block 46 follows the guidance of the plug post 49 and the sleeve 48 to press the plate into the bending groove 47 on the bending plate 4 to complete the bending operation. The reinforcing rod 43 between the upper bracket 42 and the upper plate 2 ensures structural stability.

[0050] During the welding process, the second motor 52 drives the threaded column 59 to rotate, so that the moving block 53 moves along the threaded column 59 under the guidance of the guide rail 57 and the guide block 58. The height of the welding gun 56 is adjusted by the first electric push rod 8, thereby achieving precise welding of the shell components.

[0051] When the component needs to be clamped and fixed, the second electric push rod 73 pushes the clamping plate 74 to firmly clamp the component on one side of the L-shaped plate 7 to facilitate subsequent processing operations.

[0052] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
