Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet processing, specifically to a fixture for welding sheet metal. Background Technology

[0002] In power systems, distribution cabinets are key equipment for power distribution, control, and protection, and their quality directly affects the stability and security of power supply. Plate welding is a crucial step in the manufacturing process of distribution cabinets, and its quality has a decisive impact on the overall performance of the cabinet. Precise and secure fixing of the plates during welding is fundamental to ensuring weld quality. Poor fixing can easily lead to welding deformation, irregular weld seams, and other problems, thus affecting the structural strength and electrical performance of the distribution cabinet.

[0003] Traditional welding fixtures for processing electrical distribution cabinets have many limitations. In terms of lateral fixation, most previous fixtures used a fixed-spacing structure, making it difficult to adapt to electrical distribution cabinet panels of different sizes and specifications. When welding panels of different sizes is required, the corresponding fixtures must be changed, which not only increases production costs and time but also reduces production efficiency. Furthermore, the installation and disassembly processes are complex, requiring significant manpower and time, and increasing the labor intensity of workers.

[0004] In conclusion, developing a welding fixture for processing power distribution cabinets that can flexibly adapt to different sizes of sheet metal, provide a stable and reliable fixing environment, and is easy to operate is of great practical significance. Utility Model Content

[0005] In view of this, the present invention provides a clamp for welding plates. The clamping mechanism can flexibly adjust the fixed spacing according to the size and specifications of the plate, avoiding the need to frequently change the corresponding clamp when welding plates of different sizes.

[0006] To solve the above-mentioned technical problems, this utility model provides a fixture for welding plates, including a welding platform. The welding platform is provided with a clamping mechanism for fixing the plate. The clamping mechanism consists of a horizontal clamping component and a four-corner fixing component. The horizontal clamping component includes two symmetrical and slidably mounted fixing posts on the welding platform. Each fixing post is equipped with a telescopic rod. The top of the telescopic rod is firmly connected to a top plate. The top plate is provided with a threaded rod. The bottom of the threaded rod is fixedly connected to a lower pressure plate. The four-corner fixing component includes a plurality of first threaded holes opened on the welding platform and four right-angle fixing blocks movably mounted on the welding platform.

[0007] That is, through the synergistic effect of the lateral clamping components and the four corner fixing components, the plate can be fixed from the lateral direction and the four corners of the plate, making the plate more stable during the welding process, reducing the shaking and displacement of the plate, thereby improving the welding accuracy and quality.

[0008] The lateral clamping assembly is also provided with a drive unit for driving the two fixed posts to move in opposite directions. The drive unit includes a slide groove set at the bottom of the welding platform, in which two sliders slide, and each fixed post is mounted on the corresponding slider.

[0009] That is, the distance between the two fixed posts can be easily adjusted by the drive mechanism to accommodate plates of different sizes. When welding plates of different widths is required, simply driving the two fixed posts to move towards or away from each other can adjust the clamping range, improving the versatility and applicability of the fixture.

[0010] An asynchronous motor is installed on the side wall of the slide. The output shaft of the asynchronous motor passes through the side wall of the slide and is connected to a lead screw through a coupling. The lead screw is connected to two sliders by threads.

[0011] In other words, the displacement of the slider is controlled by rotating the lead screw driven by an asynchronous motor, allowing the distance between the two fixed posts to be accurately adjusted according to the actual size of the sheet material. Simultaneously, the high transmission efficiency and stability of the lead screw drive ensure the smooth and accurate movement of the fixed posts, guaranteeing effective lateral clamping of the sheet material.

[0012] Each slider is equipped with a locking assembly on both sides to prevent slider displacement during welding. The locking assembly includes an electro-hydraulic actuator mounted on both sides of the slider and an abutment block located at the end of the telescopic shaft of the electro-hydraulic actuator.

[0013] That is, before welding, the abutment block is extended and pressed against the side wall of the slide groove by the electro-hydraulic actuator, thereby locking the position of the slider and preventing the slider from shifting during welding. This ensures that the transverse clamping assembly maintains a stable clamping state throughout the welding process, improving the accuracy and quality of welding.

[0014] A second threaded hole is provided on the top plate. Threads are machined on the outer surface of the threaded rod and the inner surface of the second threaded hole. The threaded rod and the second threaded hole are connected by threads.

[0015] In other words, the threaded connection allows for easy adjustment of the threaded rod's vertical position, thereby adjusting the pressure of the lower pressure plate on the sheet metal. When welding sheets of different thicknesses is required, the threaded rod can be rotated according to the sheet metal's thickness to ensure the lower pressure plate presses firmly against the sheet metal, achieving effective fixation.

[0016] The top of the threaded rod is securely connected with a nut.

[0017] In other words, operators can easily adjust the vertical position of the threaded rod by manually or mechanically rotating the nut, making operation more convenient and labor-saving. At the same time, the nut design also increases operational comfort and accuracy, improving the efficiency of the fixture.

[0018] The right-angle fixing block is threadedly connected to the first threaded hole on the welding platform by screws. The right-angle fixing block has a guide groove, and the screw is set in the guide groove.

[0019] In other words, the right-angle fixing block can be securely installed on the welding platform by threading multiple screws into several first threaded holes. The guide grooves allow for a certain range of positional adjustment of the right-angle fixing block during installation to accommodate plates of different sizes and shapes. This improves the versatility and flexibility of the four-corner fixing assembly, better meeting the fixing needs of different plates.

[0020] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0021] 1. The lateral clamping assembly, through sliding fixed posts, telescopic rods, a top plate, threaded rods, and a lower pressure plate, can fix the sheet metal laterally, and the fixing position can be adjusted according to the size of the sheet metal; the four-corner fixing assembly, using the first threaded hole on the welding platform and right-angle fixing blocks, can fix the four corners of the sheet metal. These two fixing methods allow the fixture to adapt to sheet metal of different sizes and shapes, enhancing its versatility and flexibility.

[0022] 2. An asynchronous motor drives the lead screw to rotate, causing the slider connected to the lead screw to slide in the groove, which in turn drives the two fixed columns to move towards each other. This allows for convenient and quick adjustment of the distance between the two fixed columns to accommodate plates of different widths and improve operational efficiency.

[0023] 3. By setting locking components on both sides of each slider, the electro-hydraulic actuator in the locking component pushes the abutment block to contact the inner wall of the groove. The friction between the two ensures that the slider is prevented from shifting during the welding process, thereby ensuring that the fixed position of the plate does not change during the welding operation, thus improving the welding quality and avoiding the impact on the welding effect caused by the displacement of the plate due to slider movement.

[0024] 4. When it is necessary to adjust the pressure of the lower pressure plate on the plate, the threaded rod can be easily rotated by turning the nut, thereby controlling the raising and lowering of the lower pressure plate, making the operation more convenient and labor-saving, and improving the ease of use.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0032] like Figures 1-5 As shown: This embodiment provides a fixture for welding plates, including a welding platform 10. The welding platform 10 is provided with a clamping mechanism 20 for fixing the plate. The clamping mechanism 20 is composed of a transverse clamping component 21 and a four-corner fixing component 22. The transverse clamping component 21 includes two symmetrical and slidably arranged fixing posts 211 on the welding platform 10. Each fixing post 211 is equipped with a telescopic rod 212. The top of the telescopic rod 212 is firmly connected to a top plate 213 by bolts. A threaded rod 214 is provided on the top plate 213 through a through hole. The bottom of the threaded rod 214 is connected to a lower pressure plate 215 by bolts. The four-corner fixing component 22 includes a plurality of first threaded holes 221 opened on the welding platform 10, and four right-angle fixing blocks 222 movably arranged on the welding platform 10.

[0033] In actual operation, when welding the panels of the distribution cabinet is required, the panels are first placed on the welding platform 10. Using the lateral clamping assembly 21, the two symmetrically arranged fixing posts 211 on the welding platform 10 are slid and their positions are adjusted to place the panels in a suitable lateral position. Next, the height of the top plate 213 is adjusted by the telescopic rod 212, moving the top plate 213 to a suitable position above the panels. Then, the threaded rod 214 on the top plate 213 is rotated, causing the bottom pressure plate 215 to move downwards until the pressure plate 215 tightly presses against the panels, completing the lateral fixation of the panels. For the four-corner fixing assembly 22, according to the size and shape of the panels, a suitable first threaded hole 221 is selected, and the right-angle fixing blocks 222 are placed on the four corners of the panels. The right-angle fixing blocks 222 are fixed to the welding platform 10 by screws 224 or other means, thus fixing the four corners of the panels.

[0034] By utilizing the cooperation of the lateral clamping assembly 21 and the four-corner fixing assembly 22, the sheet metal can be firmly fixed from multiple directions, including the lateral direction and the four corners. The lateral clamping assembly 21 ensures that the sheet metal does not shift in the lateral direction, while the lower pressure plate 215 prevents the sheet metal from wobbling up and down during welding. The four-corner fixing assembly 22 further enhances the stability of the sheet metal at the four corners, enabling the sheet metal to maintain a stable position during welding, thereby improving the accuracy and quality of welding.

[0035] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown: The transverse clamping assembly 21 is also provided with a driving component 23 for driving the two fixed posts 211 to move towards each other. The driving component 23 includes a slide groove 231 set at the bottom of the welding platform 10. Two sliders 232 slide in the slide groove 231. Each fixed post 211 is installed on the corresponding slider 232 by welding or bolting.

[0036] When the drive unit 23 is activated, the slider 232 moves within the groove 231, thereby moving the fixed post 211. For example, when welding plates of different widths is required, the drive unit 23 drives the two sliders 232 to move towards each other, so that the distance between the two fixed posts 211 adapts to the width of the plate.

[0037] The drive unit 23 makes the relative movement of the two fixed posts 211 more convenient and automated. Compared with manually adjusting the position of the fixed posts 211, the drive unit 23 can more accurately control the distance between the fixed posts 211, improving the efficiency and precision of the operation. Moreover, this automated adjustment method can adapt to different sizes of plates, increasing the versatility of the fixture.

[0038] like Figure 3 and Figure 4As shown: An asynchronous motor 233 is mounted on the side wall of the slide 231 via a motor bracket. The output shaft end of the asynchronous motor 233 passes through the side wall of the slide 231 through a through hole and is connected to a lead screw 234 with different threads on both sides via a coupling. Two sliders 232 are connected to the lead screw 234 via meshing threads.

[0039] When the asynchronous motor 233 is started, its output shaft begins to rotate, driving the lead screw 234 to rotate via the coupling. Since the lead screw 234 is threadedly connected to the two sliders 232, the rotation of the lead screw 234 causes the two sliders 232 to move towards or away from each other within the groove 231. For example, when the lead screw 234 rotates clockwise, the two sliders 232 move towards each other, causing the fixed post 211 to move closer; when the lead screw 234 rotates counterclockwise, the two sliders 232 move away from each other, causing the fixed post 211 to move away.

[0040] A stable and precise drive is provided through the cooperation of asynchronous motor 233 and lead screw 234. Asynchronous motor 233 has good speed regulation performance, and the moving speed of slider 232 can be adjusted according to actual needs. The transmission using lead screw 234 has high precision and stability, and can accurately control the moving distance of slider 232, thereby ensuring accurate adjustment of the distance between fixed posts 211, further improving the accuracy of plate fixing and welding quality.

[0041] like Figure 4 and Figure 5 As shown: Each slider 232 has a locking assembly 24 on both sides to prevent displacement of the slider 232 during welding. The locking assembly 24 includes an electro-hydraulic actuator 241 fixed to both sides of the slider 232 by bolts, and an abutment block 242 fastened to the end of the telescopic shaft of the electro-hydraulic actuator 241 by screws 224. A cable management box is opened on the side wall of the slide 231, and a control element for the electro-hydraulic actuator 241 is installed on the top of the cable management box. The control element is connected to the electro-hydraulic actuator 241 through a signal line to control the reciprocating push-pull linear motion of the telescopic rod 212 of the electro-hydraulic actuator 241.

[0042] Before welding, the electro-hydraulic actuator 241 is activated, causing the telescopic rod 212 of the actuator 241 to extend and drive the end abutment block 242 to abut tightly against the side wall of the slide groove 231. In this way, even if the slider 232 is affected by external forces such as vibration generated during welding, it will not be displaced.

[0043] The locking assembly 24 effectively prevents the slider 232 from shifting by tightly abutting the abutting block 242 against the side wall of the slide 231, thus ensuring the stability of the entire fixture during the welding process.

[0044] like Figure 1 and Figure 3As shown: A second threaded hole 216 is provided on the top plate 213. Threads are machined on the outer surface of the threaded rod 214 and the inner surface of the second threaded hole 216. The threaded rod 214 and the second threaded hole 216 are threaded together.

[0045] When the position of the lower pressure plate 215 needs to be adjusted, the threaded rod 214 is rotated. Since the threaded rod 214 is threadedly connected to the second threaded hole 216, the threaded rod 214 will move up and down within the second threaded hole 216, thereby causing the lower pressure plate 215 to move up and down. For example, when it is necessary to press the plate, rotating the threaded rod 214 clockwise will move the lower pressure plate 215 downward; when it is necessary to loosen the plate, rotating the threaded rod 214 counterclockwise will move the lower pressure plate 215 upward.

[0046] The threaded connection makes the position adjustment of the lower pressure plate 215 more convenient and precise. By rotating the threaded rod 214, the descent distance of the lower pressure plate 215 can be precisely controlled according to the thickness of the plate and actual needs, thereby achieving different degrees of pressing on the plate and ensuring the plate is firmly fixed during the welding process.

[0047] like Figures 3-5 As shown: The top of the threaded rod 214 is securely connected to the nut 217.

[0048] A nut 217 is securely attached to the top of the threaded rod 214. An operator can rotate the threaded rod 214 by turning the nut 217 using a wrench or electric wrench. The nut 217 provides a large working surface, facilitating the application of force. For example, when a quick adjustment of the position of the lower pressure plate 215 is needed, the operator can rotate the nut 217 using an electric wrench.

[0049] The convenience of operation is improved by using nut 217. Compared to directly rotating the threaded rod 214, rotating by turning nut 217 is more effortless and comfortable, especially when the position of the lower pressure plate 215 needs to be frequently adjusted, which can improve operating efficiency and reduce the labor intensity of operators.

[0050] like Figure 2 As shown: The right-angle fixing block 222 is threadedly connected to several first threaded holes 221 on the welding platform 10 by several screws 224. The right-angle fixing block 222 is provided with a guide groove 223, and the screws 224 are set in the guide groove 223.

[0051] When installing the right-angle fixing block 222, the right-angle fixing block 222 is placed in a suitable position according to the position of the plate and the position of the first threaded hole 221 on the welding platform 10. Then, the position of the screw 224 is adjusted by the guide groove 223 so that the screw 224 is aligned with the first threaded hole 221. Finally, the screw 224 is tightened to fix the right-angle fixing block 222 to the welding platform 10.

[0052] The guide groove 223 increases the installation flexibility of the right-angle fixing block 222. The guide groove 223 allows the screw 224 to be adjusted within a certain range, enabling the right-angle fixing block 222 to better adapt to plates of different sizes and positions, improving the fixture's adaptability to different specifications of plates, and further enhancing the fixture's versatility.

[0053] The method of using this utility model is as follows: Place the plate to be welded flat on the welding platform 10, initially adjust the position of the plate so that it is roughly in the center of the welding platform 10, then start the asynchronous motor 233, drive the slider 232 to move towards each other through the lead screw 234, adjust the distance between the two fixed columns 211 by the movement of the slider 232, when the fixed column 211 moves to the appropriate position, turn off the asynchronous motor 233, start the electro-hydraulic push rod 241, so that the telescopic rod 212 of the electro-hydraulic push rod 241 extends, and presses the abutment block 242 tightly against the side wall of the slide groove 231, using the friction between the two to prevent the slider 232 from shifting during the welding process, and then turn the nut 217 with an electric wrench so that the lower pressure plate 215 presses tightly against the upper surface of the plate.

[0054] Then, based on the size and shape of the plate, select the appropriate position of the first threaded hole 221, place the right-angle fixing block 222 at the four corners of the plate, pass the screw 224 through the guide groove 223 on the right-angle fixing block 222, and then connect it with the first threaded hole 221 on the welding platform 10. Tighten the screw 224 to firmly fix the right-angle fixing block 222 at the four corners of the plate.

[0055] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0056] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
