Description

Technical Field

[0001] This utility model relates to the field of power distribution switchgear technology, specifically a positioning device for processing power distribution switchgear. Background Technology

[0002] As is well known, switchgear is an important control and protection device in power systems, and its manufacturing process involves a large number of sheet metal processing, welding, and component assembly procedures. Among these procedures, ensuring the precise and stable positioning of the switchgear body and its key components (such as side panels, mounting plates, busbar frames, etc.) is crucial, as it directly affects the product's dimensional accuracy, assembly interchangeability, and overall quality.

[0003] Traditional positioning devices are gradually failing to meet the needs of modern processing, mainly due to the following technical defects. First, the positioning dimension is singular and the horizontal fixation is unstable. Most devices can only position in one direction (such as only horizontal or vertical). During processing, external impacts can easily cause the cabinet to tilt and slide, resulting in dimensional deviations, misalignment of joints, and affecting assembly accuracy. Second, there is a lack of three-dimensional fixation, and there is a risk of displacement in the vertical direction. Traditional devices focus on horizontal fixation but neglect vertical reinforcement. There is no effective downward pressure constraint during top processing, and the top is prone to tilting due to upward force, which can damage the positioning reference. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a positioning device for processing power distribution switchgear, which has the following advantages:

[0016] The positioning device used for processing this power distribution switchgear, through its positioning mechanism and vertical fixing mechanism, allows for horizontal clamping by starting the first motor via the first bidirectional screw and driving the first positioning plate. Starting the second motor via the second bidirectional screw allows for vertical clamping by driving the second positioning plate. Horizontal positioning restricts the switchgear from shifting in the width direction, while vertical positioning restricts displacement in the depth direction. This dual positioning ensures that the switchgear has no displacement space on the horizontal plane. The vertical fixing mechanism is activated after the positioning mechanism has completed horizontal fixing. It drives the threaded rod to rotate via the third motor, causing the square nut and the top fixing plate to descend vertically, applying downward pressure to the top of the switchgear from the vertical direction. This, together with the horizontal clamping and vertical clamping, forms a three-dimensional fixing system. Compared to single-direction positioning, this system effectively resists external impacts during processing, preventing the cabinet from tilting or sliding and providing a stable foundation for subsequent processing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4A positioning device for processing power distribution switchgear includes a base 1, a positioning mechanism, and a vertical fixing mechanism. A support mechanism is installed on the bottom wall of the base 1, the positioning mechanism is installed on the top wall of the base 1, and the vertical fixing mechanism is installed on the back wall of the base 1. The positioning mechanism includes a first bidirectional screw 2, a first slider 3, a first positioning plate 4, a first motor 5, a second bidirectional screw 6, a second slider 7, a second positioning plate 8, and a second motor 9. A first rectangular groove 10 is horizontally formed on the top wall of the base 1. The first bidirectional screw 2 is rotatably installed within the first rectangular groove 10. The first slider 3 is threaded onto both the left and right ends of the first bidirectional screw 2. The top walls of both sets of first sliders 3 are fitted with the first positioning mechanism. Plate 4, one end of the first bidirectional screw 2 passes through the first rectangular slot 10 to install the first motor 5, the top of the base 1 has a second rectangular slot 11 longitudinally opened, the second bidirectional screw 6 is rotatably installed in the second rectangular slot 11, the front and rear ends of the second bidirectional screw 6 are threaded with the second slider 7, the top walls of the two sets of second sliders 7 are each equipped with the second positioning plate 8, one end of the second bidirectional screw 6 passes through the second rectangular slot 11 to install the second motor 9. In this embodiment, when in use, the electrical components in this device are connected to the control system, the switch cabinet is placed stably on the top wall of the base 1 manually or with the help of hoisting equipment, and then the first motor 5 is started through the control system, the first motor 5 outputs The shaft drives the first bidirectional screw 2 to rotate within the first rectangular groove 10. Since the threads at both ends of the first bidirectional screw 2 rotate in opposite directions, the two sets of first sliders 3 move towards each other along the first rectangular groove 10, thereby driving the two sets of first positioning plates 4 to move synchronously towards both sides of the switchgear until the two sets of first positioning plates 4 contact the side walls of the power distribution switchgear and achieve positioning and clamping. The first motor 5 is then shut off, completing the lateral positioning and preventing the switchgear from shifting laterally during processing. The second motor 9 is then started, driving the second bidirectional screw 6 to rotate within the second rectangular groove 11. Similarly, the two sets of second sliders 7 move towards each other along the second rectangular groove 11, driving the two sets of second positioning plates 8 to move towards the front and rear sides of the switchgear until the second positioning plates 8 are firmly against the front and rear side walls of the switchgear. After close contact and shutting off the second motor 9, the longitudinal positioning is completed. At this point, the switch cabinet is completely fixed in the horizontal direction (lateral and longitudinal) and cannot be displaced. Subsequently, the vertical fixing mechanism on the back wall of the base 1 is activated to achieve auxiliary support and fixation of the top of the power distribution switch cabinet. The horizontal direction is fixed by dual positioning in the lateral and longitudinal directions, and the vertical direction is reinforced by the vertical fixing mechanism. The switch cabinet is fixed in all directions, and there will be no displacement, tilting or lifting during the processing, avoiding processing accidents caused by loose switch cabinet. This device is not only suitable for processing power distribution switch cabinets, but can also be adapted to the positioning and fixing of metal cabinets of similar size (such as distribution boxes and control cabinets) according to needs. No major modifications are required to the device, only the positioning parameters need to be adjusted. The equipment has strong versatility.

[0024] Preferably, in this embodiment, the vertical fixing mechanism includes a support plate 12, a groove 13, a threaded rod 14, a square nut 15, a top fixing plate 16, and a third motor 17. The support plate 12 is installed on the back wall of the base 1. The groove 13 is formed at one end of the support plate 12 near the positioning mechanism. The threaded rod 14 is rotatably installed in the groove 13. The square nut 15 is threaded onto the outer wall of the threaded rod 14. The top fixing plate 16 is fixedly installed on the side wall of the square nut 15. The top end of the threaded rod 14 passes through the groove 13 to install the third motor 17. Before the vertical fixing mechanism is started, after the positioning mechanism has fixed the power distribution switch cabinet horizontally, the third motor 17 is started. The output shaft of the third motor 17 drives the threaded rod 14 to rotate clockwise in the groove 13 of the support plate 12. Since the square nut 15 is threadedly connected to the threaded rod 14, and the groove 13 is threaded onto the support plate 12, the third motor 17 is started. The output shaft of the third motor 17 drives the threaded rod 14 to rotate clockwise in the groove 13 of the support plate 12. The square nut 15 has a guiding and limiting function (the outer wall of the square nut 15 is in contact with the inner wall of the groove 13 and cannot rotate synchronously with the threaded rod 14). Therefore, the rotational motion of the threaded rod 14 is converted into the vertical downward movement of the square nut 15 along the groove 13. The square nut 15 drives the top fixing plate 16 fixed on the side wall to move downward synchronously, controlling the descent speed and stroke of the top fixing plate 16. For example, for a switch cabinet with a height of 2000mm, the top fixing plate 16 descends from the initial height (100-150mm higher than the top of the switch cabinet) until its bottom surface is completely in contact with the top of the switch cabinet, realizing the auxiliary fixation of the top of the power distribution switch cabinet. Together with the horizontal positioning mechanism, it forms a three-dimensional fixing system of "horizontal clamping + vertical downward pressure". In the entire processing process (such as drilling holes in the switch cabinet, installing guide rails, etc.), it ensures that the downward pressure of the top fixing plate 16 is constant, avoiding the top of the switch cabinet from tilting or shifting due to vibration or external impact.

[0025] Preferably, in this embodiment, the support mechanism includes support legs 18, and the support legs 18 are installed at all four corners of the bottom wall of the base 1. The four corners of the bottom wall of the base 1 are key stress points of the rectangular structure. Installing support legs 18 at these points can form a stable "four-point support" structure. Compared with single-sided support or middle support, the four-corner support can distribute the weight of the base 1 and the positioning mechanism and power distribution switch cabinet above to the greatest extent (the overall weight of the power distribution switch cabinet can usually reach 500-1000kg during processing), avoiding the base 1 from tilting or deforming due to uneven stress. At the same time, the four-point support can keep the top wall of the base 1 in a horizontal state, providing a foundation for the accurate operation of the subsequent positioning mechanism (such as the first bidirectional screw 2 and the second bidirectional screw 6), and preventing the positioning slider from sliding deviation due to the tilt of the base 1, which would affect the horizontal positioning accuracy of the switch cabinet.

[0026] Preferably, in this embodiment, the first motor 5, the second motor 9, and the third motor 17 are all servo motors. For the first motor 5 driving the first bidirectional screw 2, the servo motor can precisely control the number of rotations of the screw, so that the error of the lateral movement distance of the two sets of first sliders 3 is controlled within ±0.05mm, ensuring that the first positioning plate 4 is accurately clamped to the switch cabinet in the lateral direction, and avoiding clamping offset caused by insufficient motor control precision. Similarly, the second motor 9 driving the second bidirectional screw 6 can accurately adjust the longitudinal movement distance of the two sets of second sliders 7, so that the contact position error between the second positioning plate 8 and the front and rear walls of the switch cabinet is minimal, ensuring longitudinal positioning accuracy. The third motor 17 driving the threaded rod 14 can adjust the descent height of the top fixing plate 16 by precisely controlling the number of rotations of the threaded rod 14. For example, for different switch cabinets with a height difference of only 5mm, the downward stroke of the top fixing plate 16 can be precisely controlled to avoid excessive downward pressure causing deformation of the top of the cabinet or insufficient downward pressure affecting the fixing effect.

[0027] Preferably, in this embodiment, the first bidirectional screw 2 and the second bidirectional screw 6 are designed to be vertically interlaced. The first bidirectional screw 2, in the horizontal direction, drives the first positioning plate 4 to achieve "width clamping" from the left and right sides of the switch cabinet, restricting the cabinet's displacement along the horizontal direction (X-axis). The second bidirectional screw 6, in the vertical direction, drives the second positioning plate 8 to achieve "depth clamping" from the front and rear sides of the switch cabinet, restricting the cabinet's displacement along the vertical direction (Y-axis). This vertically interlaced design ensures that the positioning of the two key dimensions (horizontal and vertical) in the horizontal direction does not interfere with each other, forming a "bidirectional clamping + double limiting" fixing effect. This avoids the problem of "fixed in one direction and prone to displacement in the other direction" in traditional parallel designs, ensuring that the switch cabinet has no displacement space on the horizontal plane.

[0028] Preferably, in this embodiment, the outer walls of the first positioning plate 4, the second positioning plate 8, and the top fixing plate 16 are all equipped with rubber pads 19. The rubber pads 19 have a soft surface and a moderate coefficient of friction. When in contact with the cabinet surface, they can prevent the edges and corners of the positioning plate (metal material) from directly scratching the cabinet paint or powder coating, thus preventing appearance defects such as "scratches and paint peeling". Especially for light-colored switch cabinets (such as gray and white), they can effectively reduce the appearance defect rate.

[0029] Preferably, in this embodiment, the thickness of the rubber pad 19 is 5-15mm, and its Shore hardness is A60-A80. Setting the thickness of the rubber pad 19 to 5-15mm avoids insufficient protection due to being too thin, and also prevents positioning deviation caused by being too thick. At the same time, it can be flexibly adjusted according to the specifications of the switch cabinet. The Shore hardness A60-A80 is in the "medium hard" range of rubber materials, which has sufficient elasticity to achieve buffering, and good support to ensure positioning effect, avoiding the defects of being too soft or too hard.
