Abstract
Description
Technical Field
[0001] This utility model relates to the field of tank processing technology, and in particular to a tank pre-welding device. Background Technology
[0002] During the production process, the tank body and the lid are produced separately. Then, the tank body and the lid are welded together. Since the tank body and the lid need to be welded around the circumference, in order to ensure the positional accuracy of the welding and the quality requirements of the circumferential weld, the tank body and the lid need to be pre-welded before welding. A clamp is used to first restrict the position of the tank body. Then, one operator aligns the lid with the tank body, and another operator performs spot welding on the connection between the tank body and the lid.
[0003] The aforementioned pre-welding operation requires the cooperation of two operators. If the operator responsible for spot welding does not promptly remind the other operator to cover their eyes, it may easily cause injury to the other operator's eyes, and improper cooperation may lead to risks. Utility Model Content
[0004] To reduce the risks associated with pre-welding operations, this application provides a tank pre-welding device.
[0005] The pre-welding device for tank body provided in this application adopts the following technical solution:
[0006] A pre-welding device for a can body includes a frame and a first clamp and a second clamp mounted on the frame. The first clamp includes a fixed base, a first drive component, and a movable base. The fixed base is fixedly mounted on the frame, and the movable base is located directly above the fixed base. The first drive component is mounted on the frame and is used to drive the movable base to move vertically. The fixed base and the movable base have arc-shaped grooves that match the can body on their opposite sides. The movable base and the fixed base are used to clamp the can body. The second clamp includes a second drive component and an abutment block. The second drive component is mounted on the frame and is used to drive the abutment block to move along the horizontal axis of the clamped can body. The abutment block is located on the side of the can cover away from the can body and is used to push the can cover to press against the can body.
[0007] By adopting the above technical solution, the operator first uses the first clamp to fix the position of the can body, then manually aligns the can lid with the can body, and then the abutting block of the second clamp pushes the can lid to press against the can body. Then the operator performs spot welding on the connection between the can body and the can lid. The whole process can be completed by only one operator without the cooperation of other operators. When the operator is welding, he / she can also better protect himself / herself out of instinct, thereby reducing the risks in the pre-welding operation.
[0008] Preferably, the abutting block includes a first block, a second block, and a spring. The driving component drives the second block to move. A sliding groove is provided on the side of the second block facing the can lid. The first block is slidably connected in the sliding groove along the moving direction parallel to the second block. The spring is located in the sliding groove, and its two ends abut against the first block and the bottom wall of the sliding groove, respectively. A limiting block is provided on the side wall of the first block, and a limiting groove is provided on the inner wall of the sliding groove. The limiting block is slidably connected in the limiting groove.
[0009] By adopting the above technical solution, the operator aligns the can lid with the can body, and the second drive unit drives the second block to move towards the can lid until the first block abuts against the can lid. At this time, the second block continues to move towards the can lid, and the pressure of the first block against the can lid will gradually increase. Since it is difficult for the can lid to be completely aligned with the can body at one time, the initial pressure of the first block on the can lid is enough to ensure that the can lid will not move without external force. Then the operator manually adjusts the position of the can lid so that the can lid is completely aligned with the can body, and then increases the pressure of the first block on the can lid so that the can lid is completely pressed against the can body. Then the operator can perform spot welding at the connection between the can body and the can lid.
[0010] Preferably, the first piece has a groove on the side away from the can lid, and the end of the spring away from the bottom wall of the groove abuts against the bottom wall of the groove.
[0011] By adopting the above technical solution, the compressed spring can be located in the groove. When the first piece moves to the second piece and presses against the bottom wall of the groove, the thrust of the second piece is fully applied to the first piece, which can drive the first piece to press against the can lid completely.
[0012] Preferably, the first block is cylindrical, and a cylindrical groove is coaxially formed on one side of the first block facing the can lid. The first block is coaxially formed with the can body in the clamped state, and an air hole is formed through the inner wall of the cylindrical groove.
[0013] By adopting the above technical solution, since most can lids are arc-shaped, the cylindrical groove can be opened to better match the arc-shaped protrusion in the center of the can lid. The arc-shaped protrusion of the can lid itself can play a certain guiding role, helping the can lid to automatically adjust to be coaxial with the first piece.
[0014] Preferably, the first piece has a rubber pad on the side facing the can lid.
[0015] By adopting the above technical solution, the rubber pad can better fit the surface of the can lid, while reducing wear on the can lid.
[0016] Preferably, the rubber pad has several countersunk holes along the circumferential direction, the countersunk holes are used to engage with screws, and the rubber pad is locked onto the first piece by screws.
[0017] By adopting the above technical solution, the rubber gasket is detachable, and the fit with the can lid can be maintained by replacing the rubber gasket.
[0018] Preferably, it also includes an auxiliary component for aligning the can lid with the can body. The auxiliary component includes a drive component three and a V-shaped plate. The drive component three is mounted on the frame and is used to drive the V-shaped plate to move vertically. The V-shaped plate is located directly below the can body and the can lid, and the length direction of the V-shaped plate is parallel to the axial direction of the can body.
[0019] By adopting the above technical solution, during the process of aligning the can lid with the can body, the V-shaped plate can support the can lid from below. Then the V-shaped plate moves to abut against the can body, while the second plate acts on the can lid. The operator helps the can lid stand up. The inclined surface on the V-shaped plate can automatically help the axis of the can lid align with the can body. Then the second plate continues to act on the can lid, so that the can lid is pressed tightly against the can body.
[0020] The main technical effects of this utility model are reflected in the following aspects:
[0021] 1. In this utility model, the operator first uses the first clamp to fix the position of the can body, then manually aligns the can lid with the can body, and then the abutting block of the second clamp pushes the can lid to press against the can body. Then the operator performs spot welding on the connection between the can body and the can lid. The whole process can be completed by only one operator without the cooperation of other operators. When the operator is welding, he / she can also better protect himself / herself out of instinct, thereby reducing the risks in the pre-welding operation.
[0022] 2. By setting a groove, the compressed spring can be located in the groove. When the first block moves to the second block and presses against the bottom wall of the slide, the thrust of the second block is completely applied to the first block, which can drive the first block to press against the can lid completely.
[0023] 3. By setting a cylindrical groove, since most can lids are arc-shaped, the cylindrical groove can better match the arc-shaped protrusion in the center of the can lid. The arc-shaped protrusion of the can lid itself can play a certain guiding role, helping the can lid to automatically adjust to be coaxial with the first piece. Attached Figure Description

Detailed Implementation
[0028] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail to make the technical solution of this application easier to understand and master.
[0029] This application discloses a tank pre-welding device.
[0030] Reference Figure 1 and Figure 2 This embodiment of a can pre-welding device includes a frame 1 and a first clamp 2 and a second clamp 3 mounted on the frame 1. The first clamp 2 includes a fixed base 21, a first driving member 22, and a movable base 23. The fixed base 21 is fixedly mounted on the frame 1, and the movable base 23 is located directly above the fixed base 21 and is slidably connected to the frame 1 in the vertical direction. The first driving member 22 is mounted on the frame 1 and is used to drive the movable base 23 to move in the vertical direction. The fixed base 21 and the movable base 23 have arc-shaped grooves 24 that match the can body 51 on their opposite sides. The movable base 23 and the fixed base 21 are used to clamp the can body 51. The second clamp 3 includes a second driving member 31 and an abutment block 32. The second driving member 31 is mounted on the frame 1 and is used to drive the abutment block 32 to move along the horizontal axis direction of the clamped can body 51. The abutment block 32 is located on the side of the can cover 52 away from the can body 51 and is used to push the can cover 52 to press against the can body 51.
[0031] Reference Figure 1 and Figure 2 The operator first uses the first clamp 2 to fix the position of the can body 51, then manually aligns the can lid 52 with the can body 51. Then, the abutment block 32 of the second clamp 3 pushes the can lid 52 to press against the can body 51. Then, the operator performs spot welding on the connection between the can body 51 and the can lid 52. The whole process can be completed by only one operator without the cooperation of other operators. When the operator is welding, he / she can also better protect himself / herself out of instinct, thereby reducing the risks in the pre-welding operation.
[0032] Reference Figure 1 and Figure 3The abutment block 32 includes a first block 321, a second block 322, and a spring 323. A driving component 31 drives the second block 322 to move. A groove 3221 is formed on the side of the second block 322 facing the can lid 52. The first block 321 is slidably connected within the groove 3221 along a direction parallel to the movement of the second block 322. The spring 323 is located within the groove 3221, with its two ends abutting against the first block 321 and the bottom wall of the groove 3221, respectively. A limiting block 3211 is provided on the side wall of the first block 321, and a limiting groove 3222 is formed on the inner wall of the groove 3221. The limiting block 3211 is slidably connected within the limiting groove 3222. The cooperation between the limiting block 3211 and the limiting groove 3222 prevents the first block 321 from detaching from the second block 322.
[0033] Reference Figure 1 and Figure 3 The operator aligns the can lid 52 with the can body 51. The second drive unit 31 drives the second block 322 to move towards the can lid 52 until the first block 321 abuts against the can lid 52. At this point, the second block 322 continues to move towards the can lid 52, and the pressure of the first block 321 against the can lid 52 gradually increases. Since it is difficult for the can lid 52 to be completely aligned with the can body 51 at once, the initial pressure of the first block 321 on the can lid 52 is sufficient to ensure that the can lid 52 will not move without external force. Then, the operator manually adjusts the position of the can lid 52 so that the can lid 52 is completely aligned with the can body 51. Then, the pressure of the first block 321 on the can lid 52 is increased so that the can lid 52 is completely pressed against the can body 51. Then, the operator can perform spot welding on the connection between the can body 51 and the can lid 52.
[0034] Reference Figure 1 and Figure 3 The first piece 321 has a groove 3212 on its side away from the can lid 52, and the end of the spring 323 away from the bottom wall of the slide 3221 abuts against the bottom wall of the groove 3212. The compressed spring 323 can be located in the groove 3212. When the first piece 321 moves to the point where the second piece 322 abuts against the bottom wall of the slide 3221, the thrust of the second piece 322 is fully applied to the first piece 321, which can drive the first piece 321 to fully abut against the can lid 52.
[0035] Reference Figure 1 and Figure 3 The first piece 321 is cylindrical. A cylindrical groove 3213 is coaxially formed on the side of the first piece 321 facing the can lid 52. The first piece 321 is coaxially formed with the can body 51 in the clamped state. An air hole 3214 is formed through the inner wall of the cylindrical groove 3213.
[0036] Reference Figure 1 and Figure 3Since the can lid 52 is mostly arc-shaped, the cylindrical groove 3213 can be opened to better match the arc-shaped protrusion in the center of the can lid 52. The arc-shaped protrusion of the can lid 52 itself can play a certain guiding role, helping the can lid 52 to automatically adjust to be coaxial with the first piece 321.
[0037] Reference Figure 1 and Figure 3 The first piece 321 has a rubber pad 33 on the side facing the lid 52. The rubber pad 33 can better fit the surface of the lid 52 and reduce wear on the lid 52.
[0038] Reference Figure 1 and Figure 3 The rubber pad 33 has several countersunk holes 331 along its circumferential direction. The countersunk holes 331 are used to engage with screws 332. The rubber pad 33 is locked onto the first piece 321 by the screws 332. The rubber pad 33 is detachable, and the fit with the can lid 52 can be maintained by replacing the rubber pad 33.
[0039] Reference Figure 1 and Figure 2 It also includes an auxiliary component 4 for aligning the can lid 52 with the can body 51. The auxiliary component 4 includes a drive component 41 and a V-shaped plate 42. The drive component 41 is mounted on the frame 1 and is used to drive the V-shaped plate 42 to move in the vertical direction. The V-shaped plate 42 is located directly below the can body 51 and the can lid 52. The length direction of the V-shaped plate 42 is parallel to the axial direction of the can body 51.
[0040] Reference Figure 1 and Figure 2 During the process of aligning the can lid 52 with the can body 51, the V-shaped plate 42 supports the can lid 52 from below. Then, the V-shaped plate 42 moves to abut against the can body 51, while the second plate 322 acts on the can lid 52. The operator helps the can lid 52 stand upright, and the inclined surface on the V-shaped plate 42 automatically helps align the axis of the can lid 52 with the can body 51. Then, the second plate 322 continues to act on the can lid 52, making the can lid 52 press firmly against the can body 51. During spot welding, the V-shaped plate 42 moves down, and the can lid 52 is unobstructed circumferentially, allowing the operator to perform spot welding at any position at the connection between the can lid 52 and the can body 51.
[0041] Reference Figure 1 and Figure 2 Drive component 22 is a pneumatic cylinder, while drive components 31 and 41 are electric cylinders with more precise control. Drive components 22, 31, and 41 can also employ any structure capable of achieving the aforementioned functions.
[0042] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
