Description

Technical Field

[0001] The present application relates to the technical field related to control cabinet processing equipment, and in particular to a screw fixing tool for a cabinet panel. Background Art

[0002] A control cabinet is a device that assembles switchgear, measuring instruments, protective devices, and auxiliary equipment in an enclosed or semi-enclosed metal cabinet or on a screen according to electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, facilitate maintenance, and protect personnel and surrounding equipment. During normal operation, circuits can be connected and disconnected using manual or automatic switches. In the event of a fault or abnormal operation, protective devices disconnect the circuit or generate an alarm. Measuring instruments can display various operating parameters, adjust certain electrical parameters, and provide prompts or signals indicating deviations from normal operating conditions. Control cabinets are commonly used in power generation, distribution, and substations.

[0003] During the production of control cabinets, panels of varying sizes are assembled into a relatively closed control cabinet. This process involves screws, which are then welded to the panels and secured. Currently, manual straightening is often used to secure the screws. However, manual straightening is not only difficult to maintain verticality, but also poses a risk of burns from solder splashes due to the worker's hands being too close to the welding point. Circular array welding of multiple screws also requires scribing, a cumbersome process. Therefore, improvements are necessary. Utility Model Content

[0004] In order to address the deficiencies of the above-mentioned prior art, the present application provides a screw fixing tool on a cabinet panel, which achieves the fixation of the screw more safely and accurately, and facilitates the development of welding work.

[0005] In order to achieve the above purpose, the utility model adopts the following technologies:

[0006] A screw fixing tool for a cabinet panel includes a magnet, which is a cylindrical structure. A through hole is provided in the middle of the magnet, and a plurality of grooves are provided on the upper end surface of the magnet along its own radial circumferential array. A rotating rod is coaxially provided in the through hole. The magnet is used to fix the rotating rod and keep the rotating rod always vertical. A positioning assembly is provided between the groove and the rotating rod, which is used to position the screw when welding multiple screws in a circumferential array. A connecting rod is provided on the upper part of the rotating rod. The axis of the connecting rod is perpendicular to the axis of the rotating rod. The connecting rod is moved along its own axis in the rotating rod. A fixing assembly is provided at the end of the connecting rod away from the center of the magnet, which is used to fix the screw and keep the screw perpendicular to the cabinet panel.

[0007] The beneficial effects of this utility model are that while directly securing the screw with a fixing tool, the screw and the cabinet panel remain perpendicular, facilitating welding. This not only avoids the problem of losing verticality during manual straightening, but also avoids the potential safety hazards associated with manual straightening. Furthermore, the grooves provided in the circular array of magnets, in conjunction with the positioning assembly, can accommodate a variety of circular array welding scenarios, simplifying the work process and improving work efficiency.

[0015] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] The embodiment of the present application provides a screw fixing tool for a cabinet panel, such as Figure 1-Figure 5 As shown, it includes a magnet 1, which has a cylindrical structure. A through hole 11 is provided in the middle of the magnet 1, and a plurality of grooves 12 are provided on the upper end surface of the magnet 1 along its own radial circumferential array. A rotating rod 2 is coaxially provided in the through hole 11. The magnet 1 is used to fix the rotating rod 2 and keep the rotating rod 2 always vertical. A positioning component 3 is provided between the groove 12 and the rotating rod 2, which is used to accurately position the screw when welding multiple screws in a circular array. A connecting rod 4 is provided on the upper part of the rotating rod 2, and the axis of the connecting rod 4 is perpendicular to the axis of the rotating rod 2. The connecting rod 4 is movably arranged along its own axis in the rotating rod 2, and a fixing component 5 is provided at the end of the connecting rod 4 away from the center of the magnet 1, which is used to fix the screw and keep the screw perpendicular to the cabinet panel.

[0017] When applied, such as Figure 1-Figure 3 As shown, first place the magnet 1 horizontally on the cabinet board according to the installation position of the screw, then insert the rotating rod 2 from the through hole of the magnet 1, and the bottom surface of the rotating rod 2 and the bottom surface of the magnet 1 are in contact with the cabinet board, and then use the fixing component 5 to fix the screw and keep it perpendicular to the cabinet board. Finally, rotate the rotating rod 2 and adjust the position of the connecting rod 4 to move the screw to the installation position, and then you can start welding the screw.

[0018] To weld multiple screws in a circular array on a cabinet panel, first select a magnet 1 with a corresponding number of grooves 12 in the array. Horizontally place the magnet 1 at the center of the cabinet panel according to the screw installation position. Then, insert the rotating rod 2 through the through-hole of the magnet 1, with the bottom of the rotating rod 2 and the bottom surface of the magnet 1 both in contact with the cabinet panel. Rotate the rotating rod 2 and use the positioning assembly 3 between the grooves 12 and the rotating rod 2 to position the rotating rod 2 so that the axis of the connecting rod 4 is parallel to the grooves 12. Use the fixing assembly 5 to fix the screws and keep them perpendicular to the cabinet panel. Adjust the left and right movement of the connecting rod 4 according to the screw installation position to keep the screw in the installation position. Once completed, the screw can be welded. After the previous screw is welded, remove the rotating rod 2 and separate it from the previous screw. Then, place the rotating rod 2 back into the through hole of the magnet 1 according to the position of the next screw to be welded. Use the positioning component 3 between the groove 12 and the rotating rod 2 to position the rotating rod 2 so that the axis of the connecting rod 4 is parallel to the other groove 12. Then use the fixing component 5 to fix the screw and keep it perpendicular to the cabinet board. Then, you can start welding the screw. Repeat the above steps until all the screws are welded.

[0019] The above-mentioned structure is set up, and while it is fixed directly with the screw fixing tool, it can also keep the screw and the cabinet panel perpendicular, which is convenient for welding. The setting of the groove 12 on the magnet 1 makes the screw fixing tool suitable not only for independent welding scenarios, but also for scenarios where multiple circular arrays are required for welding. The way the magnet 1 is plugged into the rotating rod 2 allows one rotating rod 2 to be used for magnets 1 with different numbers of grooves 12. During use, it is only necessary to replace the magnet 1 according to the scenario to be welded, which not only ensures welding accuracy but also simplifies the welding process.

[0020] Optimized, such as Figure 3As shown, the upper and lower end surfaces of the magnet 1 are both provided with grooves 12, and the grooves 12 are of the same size but different in number, to accommodate the work scenarios of circular array welding of different numbers of screws. The magnet 1 used in this embodiment is provided with four grooves 12 in the circular array on the upper end surface, and six grooves 12 in the circular array on the lower end surface. When four screws need to be welded in a circular array, the magnet 1 is placed upright and then inserted into the rotating rod 2; if six screws need to be welded in a circular array, the magnet 1 is placed upside down and then inserted into the rotating rod 2. One magnet 1 can adapt to two welding work scenarios, improving the practicality of the screw fixing tool.

[0021] Specifically, such as Figure 4 and Figure 5 As shown, the positioning assembly 3 is an elastic positioning plate, one end of which is fixedly connected to the rotating rod 2, and the other end of which is engaged with the groove 12 for positioning the screw. As another structure, Figure 6 As shown, a fixing rod can be extended vertically from the side wall of the rotating rod 2, which is higher than the magnet 1. The groove 12 and the fixing rod are then connected to achieve positioning by a pin. This arrangement can more accurately align the axis of the connecting rod 4 with the groove 12 when welding multiple pieces in a circular array, thereby accurately positioning the screw rod for installation, thus ensuring the accuracy of multiple pieces in a circular array.

[0022] Specifically, such as Figure 1 、 Figure 2 as well as Figure 4 As shown, the fixing assembly 5 includes two parallel and spaced-apart clamping blocks 51, which are used to clamp the screw and keep it in a vertical state. The clamping surface of one of the clamping blocks 51 is a V-shaped surface, and the clamping surface of the other clamping block 51 is a plane. The V-shaped surface and the plane are used to contact the screw together, so that the screw can be kept in a vertical state with respect to the cabinet panel more stably. The end of the connecting rod 4 away from the center of the magnet 1 is connected to the back side of the clamping surface of one of the clamping blocks 51. A spring 52 is connected between the two clamping blocks 51, which increases the diameter range of the screw that can be clamped by the two clamping blocks 51, which not only indirectly provides a clamping force between the two clamping surfaces, but also expands the scope of application of the fixing tool.

[0023] Specifically, such as Figure 1 、 Figure 2 、 Figure 4 and Figure 5As shown, a clamping screw 6 is provided at the top of the rotating rod 2 for securing the connecting rod 4. After the screw rod is positioned by moving the connecting rod 4, the clamping screw 6 is used to clamp the portion of the connecting rod 4 that contacts the rotating rod 2. This secures the connecting rod 4 and keeps the axis of the connecting rod 4 parallel to the panel. When the fixing assembly 5 connected thereto secures the screw rod, the screw rod can be more stably maintained in a perpendicular position to the panel, making welding easier.

[0024] In application, the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
