Description

Technical Field

[0001] The present invention relates to the technical field of power cabinet processing, in particular to a tool for welding power cabinet components. Background Art

[0002] Power cabinets are important equipment used to distribute, control, and protect electricity in power systems. They are typically installed in power plants, substations, industrial facilities, and commercial or residential buildings. Power cabinets can be divided into high-voltage power cabinets, low-voltage power cabinets, power distribution cabinets, and switch cabinets, depending on their functions and usage environments.

[0003] The power cabinet is mainly composed of an outer shell, internal components (such as switchgear, relays, contactors and transformers), and busbars. The outer shell of the power cabinet is mainly made of multiple steel plates that are stamped into a specified shape and then welded. During welding, the two side frames and two bottom frames are first welded to form the outer shell-like main frame, and then other welding operations are carried out.

[0004] At present, when performing the above-mentioned welding operation, a clamping and fixing device is usually used to clamp and fix the side frames and bottom frames to be welded. However, the following problems will occur in this process: 1. When using an assembly and disassembly device directly installed on the side frames and bottom frames to implement clamping, fixing and alignment, although the side frames and bottom frames to be welded have been preliminarily assembled into a cabinet body before welding, the cabinet body as a whole is not effectively fixed. If it deviates during the welding process, it will also affect the welding effect. In addition, the device needs to be removed after welding. As a result, when processing multiple cabinet bodies, the installation and disassembly operations of the device need to be repeated, which will affect work efficiency, work intensity and labor costs.

[0005] 2. When using an integral clamping and fixing device, multiple independent driving sources are often used to clamp and fix the two side frames and the two bottom frames. The uniformity and consistency of the overall operation of the device are low, and the driving cost is increased. At the same time, under a single clamping limit, it is easy for the side frame and the bottom frame to move and contact each other when they are not aligned, or it is difficult to maintain a vertical state for stable moving contact, which in turn affects the subsequent welding effect. If the position is adjusted later, the overall processing efficiency will be affected. Summary of the Invention

[0020] 2. The present invention utilizes two pushing plates to press against the two rotating bars on the upper side to fix the rotating bar, so that the pressing block 1 on the rotating bar presses the corresponding side frame against the pressing frame and the pressing bar to complete the limiting fixation of the side frame. Secondly, the triangular frame formed by the rotating bar and the pushing plate improves the stability of the side frame during the pressing and clamping process.

At the same time, the above-mentioned clamping method also aligns the clamping column with the guide groove on the corresponding clamping block, ensuring that the side frame and the bottom frame remain vertical after alignment, avoiding the problem of the two being not vertical due to manual support, which affects the structural strength of the welded shell.

[0022] 4. In the present invention, the lower plug-in column is inserted into the corresponding connecting block, and the upper plug-in column is away from the corresponding connecting column, so as to facilitate the placement of the side frame and the bottom frame from top to bottom for welding operations and the removal of the shell after welding.

At this time, a rectangular frame for improving stability is formed by the two upper and lower clamping columns and the clamping block 1 or the clamping block 2 and the clamping block 3 in the middle of the two. There are two rectangular frames on the same side frame or bottom frame, and the adjacent rectangular frames on the side frame and the bottom frame are mutually limited and fixed by the cooperation of the corresponding clamping columns and the guide grooves, and the cooperation of the clamping strips and the clamping grooves, which further improves the stability of the overall clamping and fixing process.

[0031] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] like Figure 1 and Figure 2 As shown, a tool for welding power cabinet components includes: a horizontally arranged cross base 1, a longitudinal section of the cross base 1 is provided with two L-shaped abutting frames 2 that slide back and forth, and the two abutting frames 2 are symmetrical front and back, the upper end surface of the cross base 1 is provided with two vertically symmetrical mounting circular plates 20 whose axes are collinear with the center of the cross base 1 through a central column, the two mounting circular plates 20 are commonly provided with a clamping mechanism 4 for clamping and abutting the two side frames, the transverse section of the cross base 1 is provided with two left-right symmetrical transverse blocks 5 that slide left and right, the transverse blocks 5 are fixedly provided with a clamping plate 6, and the two abutting plates 6 are commonly provided with a clamping mechanism 7 for clamping and abutting the two bottom frames.

[0033] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown, the clamping mechanism 1 4 includes a rotating bar 40, and two rotating bars 40 distributed up and down and with axes colinear with the axis of the mounting circular plate 20 are rotatably provided on the mounting circular plate 20, and a clamping block 1 400 is provided on the side of the rotating bar 40 away from the mounting circular plate 20, and a clamping bar 401 corresponding to the clamping block 1 400 is provided on the left and right end surfaces of the clamping frame 2, and the clamping mechanism 2 7 includes a U-shaped frame 70, and the opposite back surfaces of the two clamping plates 6 are fixed with a U-shaped frame 70 with an opening facing downward through a connecting bar, and two vertical sections of the U-shaped frame 70 are provided with two clamping blocks 2 700 distributed left and right through a T-shaped bar, and the T-shaped bar is slidably arranged on the vertical section of the U-shaped frame 70, and the upper end surface of the clamping block 2 700 is fixed with a clamping block 3 701 through a telescopic rod 1.

[0034] like Figure 1 and Figure 2 As shown, a square block 8 is provided on the clamping plate 6 for sliding up and down, and a structural column 80 with an axis extending from left to right and sliding through the square block 8 is fixed on the upper end surface of the upper mounting circular plate 20 through the structural block, a push plate 81 is provided on the structural column 80 for sliding left and right, and a driving unit 9 is provided on the clamping plate 6.

[0035] When working (see Figure 1-Figure 5 ), first move the two abutting frames 2 so that the distance between them is the required welding length of the two side frames, providing a placement reference for the subsequent welding alignment process. Secondly, the adjustability of the position of the abutting frames 2 facilitates the welding operation of side frames and bottom frames of different sizes. After that, the staff will place the two side frames and two bottom frames that need to be welded at the designated positions (see Figure 1 ), at this time, the front side's tightening block 1 400 and the corresponding tightening strip 401 cooperate with each other to initially support the side frame, and the two upper side's tightening blocks 3 701 initially support the bottom frame, and then the clamping mechanism 1 4 works to make the two mounting circular plates 20 move away from each other, and then the four tightening blocks 1 400 on the same side are stretched inward to limit and fix the corresponding side frames, and the two tightening blocks 2 700 and the corresponding two tightening blocks 3 701 on the same side cooperate with each other to stretch inward to limit and fix the corresponding bottom frames, and the driving unit 9 works The two pushing plates 81 are brought closer to each other, and at the same time, the pushing plates 81 are pressed against the two rotating bars 40 on the upper side. In the process of approaching each other, the pressing block 400 in the clamping mechanism 4 and the corresponding pressing bar 401 cooperate with each other to clamp the side frames front and back, guide the bottom frame and the two side frames to fit tightly together, and also serve as a left and right clamping limit for the bottom frame. Finally, the two bottom frames and the two side frames are all tightly together, and the side frames and the bottom frame are manually welded at the tight joints using existing external welding equipment (such as a welding machine).

[0036] In the above process, the triangular structure formed between the push plate 81 and the two rotating bars 40, the triangular structure formed by the clamping blocks 400 on different rotating bars 40, and the rectangular frame formed by the structural column 80, the push plate 81, and the cross base 1 improve the connection stability between the entire equipment and the bottom frame and the side frame, thereby improving the stability of the overall welding process, while ensuring the accuracy of the docking between the side frame and the bottom frame, and facilitating high-quality welding. Secondly, in the above process, by docking two side frames and two bottom frames at the same time, the problem of increased error and slow efficiency caused by multiple docking is avoided.

[0037] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the clamping mechanism 1 4 also includes a horizontal column 41. The left and right end surfaces of the clamping frame 2 are both provided with two horizontal columns 41 distributed up and down for sliding up and down. The clamping bar 401 is slidably provided on the corresponding horizontal column 41. The upper end surface of the lower clamping bar 401 is fixedly provided with a vertical column 410 with a vertical axis and sliding through the upper clamping bar 401. The two corresponding clamping blocks 1 400 are fixedly connected by a telescopic rod 2 411 with a vertical axis. The front and rear corresponding clamping bars 401 and the clamping blocks 1 400, the two corresponding clamping blocks 2 700 on the left and right, and the two corresponding clamping blocks 1 700 on the left and right are fixedly connected. A connecting component is fixedly arranged between the tightening blocks 3 701, and the connecting component includes two connecting blocks 412 and a plug-in column 413 fixedly arranged on one of the connecting blocks 412 and sliding through the other connecting block 412. The tightening block 1 400 and the tightening strip 401 are fixedly connected to the corresponding connecting blocks 412 respectively, and the tightening block 2 700 and the tightening block 3 701 are fixedly connected to the corresponding connecting blocks 412 respectively, and the length of the plug-in column 413 on the lower side is greater than that of the plug-in column 413 on the upper side. The tightening blocks 2 700 on the far left and the far right are both slid back and forth on the T-shaped bar through the corresponding connecting blocks 412.

[0038] like Figure 2 and Figure 3 As shown, the clamping mechanism 1 4 also includes a rectangular groove 42, and rectangular grooves 42 are formed at both ends of the rotating bar 40. A telescopic rod 3 420 is fixedly provided between the two rotating bars 40 facing each other, and U-shaped bars 421 are fixedly provided on the opposite surfaces of the front and rear clamping blocks 1 400. A matching column 422 with a vertical axis that slides through the corresponding rectangular groove 42 is fixed on the U-shaped bar 421.

[0039] like Figure 2As shown, a driving group is provided on the cross base 1, and the driving group includes a bidirectional screw rod 43. The upper end surface of the cross base 1 is rotatably provided with a bidirectional screw rod 43 with a vertical axis and passing through two mounting circular plates 20, and the bidirectional screw rod 43 is threadedly engaged with the two mounting circular plates 20, and the bidirectional screw rod 43 is connected to an external motor 1 (not shown in the figure).

[0040] like Figure 1 、 Figure 4 and Figure 5 As shown, the clamping mechanism 2 7 also includes a hinged rod 71, and the end faces of the clamping block 3 701 and the clamping block 2 700 facing the mounting circular plate 20 are both hingedly provided with a hinged rod 71, and the upper end face of the upper matching column 422 and the lower end face of the lower matching column 422 are both rotatably provided with a guide block 710, and the hinged rod 71 slides through the guide block 710 on the same side.

[0041] like Figures 1-6 As shown, during operation, after the two side frames are placed from top to bottom, the two upper clamping blocks 400 on the same side provide preliminary support to the side frames by contacting the horizontal sections of the side frames. During this process, the clamping strips 401 maintain a certain distance from the corresponding clamping blocks 400, which can prevent the side frames from falling off while placing the side frames. After that, the external motor 1 drives the bidirectional screw rod 43 to rotate synchronously. Through the cooperation between the bidirectional screw rod 43 and the two mounting circular plates 20, the two mounting circular plates 20 are moved away from each other, and the mounting circular plates 20 drive the corresponding clamping blocks 400 to move synchronously through the two rotating strips 40 thereon. When the guide block 710 moves, the two upper and lower corresponding clamping blocks 400 move away from each other, and the four clamping blocks 400 corresponding to the same side frame move away to complete the internal expansion and clamping of the side frame in the upper and lower directions. Secondly, through the coordinated transmission between the hinge rod 71 and the guide block 710, the clamping block 400 drives the adjacent clamping block 3 701 or the clamping block 2 700 to move synchronously, so the upper and lower corresponding clamping blocks 2 700 and the clamping block 3 701 move away from each other, and the internal expansion and clamping of the bottom frame in the upper and lower directions are completed through the movement of the corresponding clamping blocks 2 700 and the clamping block 3 701 in the same bottom frame, and the side frame and the bottom frame are aligned up and down.

[0042] At the same time, the driving unit 9 works to make the two clamping plates 6 approach each other. The clamping plates 6 push the corresponding pushing plates 81 during the movement, and the two pushing plates 81 approach each other. During the movement of the pushing plates 81, the two upper rotating bars 40 are pushed to deflect synchronously, that is, the angle between the two upper rotating bars 40 increases, and the upper rotating bar 40 drives the lower rotating bar 40 to rotate synchronously through the telescopic rod 3 420. During the rotation of the rotating bar 40, the cooperation between the rectangular groove 42 on the rotating bar 40 and the matching column 422 makes the U-shaped bar 421 drive the corresponding clamping block 400 to approach the corresponding clamping bar 401, and the clamping block 400 drives the connecting block 412 and the plug-in column 413 thereon to move synchronously, and the plug-in column on the upper clamping block 400 413 is inserted into the connecting block 412 on the clamping bar 401, and the clamping block 400 clamps the side frame to the clamping bar 401, so the four clamping blocks 400 on the same side cooperate with the corresponding clamping bars 401 to complete the limited clamping in the front and rear directions of the side frame, so that the distance between the two side frames is the specified distance at this time. After completing the above-mentioned clamping, the two clamping blocks 400 at the end of the side frame, the two clamping bars 401 and the two plug-in columns 413 together form a rectangular frame. Through the above-mentioned multiple rectangular frames, the stable triangular frame formed between the push plate 81 and the rotating bar 40, and the rectangular frame formed between the two clamping plates 6, the cross base 1 and the structural column 80, the stability of the side frame clamping process is improved, which is convenient for subsequent welding.

[0043] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, the clamping mechanism 2 7 includes a snap-fit ​​group 72, and the snap-fit ​​group 72 includes a spring rod 720. The clamping block 2 700 and the clamping block 3 701 away from the mounting circular plate 20 are provided with a receiving groove on the end face of the corresponding clamping strip 401, and a spring rod 720 with an axis extending from front to back is fixedly provided in the receiving groove. A snap-fit ​​strip 721 is fixedly provided on the end face of the spring rod 720 facing the clamping strip 401. The two left and right opposing clamping strips 401 are symmetrical left and right, and the two front and back opposing clamping strips 401 are symmetrical front and back. The front right clamping strip 401 is taken as an example for explanation. The clamping strip 401 is divided into a horizontal section and an inclined section inclined forward from left to right from left to right. The end face of the clamping strip 401 facing the clamping plate 6 is provided with a snap-fitting groove 722 which cooperates with the clamping strip 721 and has the same shape as the clamping strip 401.

[0044] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, the clamping group 72 also includes a clamping column 723. The clamping block 2 700 close to the mounting circular plate 20 and the clamping block 3 701 facing the end surface of the clamping block 1 400 are fixed with two clamping columns 723 distributed up and down and with the axis extending from left to right. A guide groove 724 corresponding to the clamping column 723 is opened through the clamping block 1 400.

[0045] It should be noted that, by cooperating with the hinged rod 71 and the guide block 710, the abutting block 1 400 and the abutting block 2 700 on the same side in the up and down directions move synchronously, and the abutting block 1 400 and the abutting block 3 701 on the same side move synchronously. In the process of the above-mentioned movement of the abutting plate 6, the abutting plate 6 drives the abutting block 2 700, the abutting block 3 701 and the bottom frame thereon to move synchronously. In the process of the abutting block 2 700 and the abutting block 3 701 driving the spring rod 720 and the clamping strip 721 thereon to move synchronously, the clamping strip 721 is clamped into the corresponding abutting strip 400. 1, the above-mentioned method is used to guide the movement of the corresponding clamping block 2 700 and the clamping block 3 701, thereby improving the stability and accuracy of the side frame and the bottom frame during docking. At the same time, the above-mentioned clamping method is used to make the clamping block 2 700 and the clamping block 3 701 aligned with the corresponding clamping block 1 400 in the front-to-back direction, and the clamping column 723 is aligned with the guide groove 724 on the corresponding clamping block. Secondly, the cooperation between the inclined section of the clamping strip 401 and the bottom frame makes the bottom frame gradually aligned and centered with the side edges of the two side frames during movement.

[0046] As the clamping plate 6 continues to move, the clamping columns 723 on the clamping blocks 2 700 and 3 701 are inserted into the corresponding guide grooves 724, and the clamping blocks 2 700 and 3 701 are tightly attached to the corresponding clamping block 1 400. As the clamping plate 6 continues to move, the plug-in columns 413 on the upper clamping block 3 701 are clamped into the corresponding connecting blocks 412, pressing the bottom frame between the clamping blocks 2 700 and 3 701 on the left and right sides. The above process completes the clamping of the bottom frame in the left and right directions, so that the bottom frame remains vertical and tightly aligned with the sides of the two side frames. The staff then performs welding operations.

[0047] In the above process, the plug-in column 413 is inserted into the corresponding connecting block 412 so that the two clamping blocks 2 700, the two clamping blocks 3 701, the two plug-in columns 413 and the two telescopic rods 1 on the same side in the front-to-back direction form a rectangular frame together, and the clamping column 723 is inserted into the guide groove 724 so that the corresponding clamping block 2 700 and the clamping block 1 400, the clamping block 3 701 and the clamping block 1 400 form a fixed rectangular frame together, ensuring the mutual perpendicularity and close contact between the side frame and the bottom frame, avoiding the problem of non-perpendicularity between the side frame and the bottom frame, which reduces the welding quality and affects the strength of the subsequent power cabinet.

[0048] like Figure 1 、 Figure 2 and Figure 5 As shown, the driving unit 9 includes an L-shaped frame 90, and two L-shaped frames 90 distributed front and back are fixedly provided on the opposite surfaces of the two clamping plates 6. A push bar 91 located below the structural column 80 is fixedly provided between the two L-shaped frames 90. A mounting bar 92 corresponding to the push plate 81 is slidably provided on the structural column 80. Two springs 93 distributed up and down are fixedly provided between the mounting bar 92 and the corresponding push plate 81. The mounting bar 92 is located between the left and right push bars 91.

[0049] like Figure 1 and Figure 2 As shown, the driving unit 9 also includes a bidirectional threaded rod 94. The lower end surface of the cross base 1 is fixedly provided with a bidirectional threaded rod 94 with an axis extending from left to right and passing through the two transverse blocks 5 through a mounting block. The bidirectional threaded rod 94 is threadedly engaged with the transverse blocks 5, and the bidirectional threaded rod 94 is connected to an external motor 2 (not shown in the figure).

[0050] After the side frame and the bottom frame are placed from top to bottom, the external motor 2 works to drive the bidirectional threaded rod 94 to rotate synchronously. The threaded cooperation between the bidirectional threaded rod 94 and the corresponding transverse block 5 makes the two transverse blocks 5 approach each other, and the transverse block 5 drives the corresponding clamping plate 6 to move synchronously. The clamping plate 6 drives the pushing bar 91 thereon to move synchronously through the L-shaped frame 90. The pushing bar 91 pushes the corresponding pushing plate 81 through the spring 1 93, so that the pushing plate 81 contacts the corresponding two rotating bars 40. The spring 1 93 is deformed, and the force generated by the deformation of the spring 1 93 acts on the pushing plate 81, and the pushing plate 81 pushes the corresponding two rotating bars 40 to deflect and perform the inner expansion operation of the side frame. When the side frame is stretched and tightened, the clamping plate 6 continues to move, and the spring 1 93 is continuously compressed. Then, with the continuous movement of the clamping plate 6, the inner expansion clamping of the bottom frame and the docking process of the bottom frame and the side frame are completed.

[0051] like Figure 2 As shown, the clamping frame 2 is provided with an adjustment group, and the adjustment group includes a longitudinal block 3. The longitudinal section of the cross base 1 is provided with a longitudinal block 3 for sliding back and forth. Two bolts 30 distributed front and back and with vertical axes are fixed on the longitudinal block 3, and the bolts 30 pass through the clamping frame 2. The bolts 30 are matched with nuts for fixing the clamping frame 2.

[0052] Before placing the side frames and the bottom frame, move the longitudinal block 3 so that the distances between the two clamping frames 2 and the center of the cross base 1 are the same, and at the same time, make the distance between the two clamping frames 2 the welding spacing required for the two side frames. Then tighten the nuts to fix the clamping frames 2 on the longitudinal section of the cross base 1. The adjustability of the position of the clamping frames 2 facilitates the welding operations of side frames and bottom frames of different sizes.
