[0001] This utility model relates to the technical field of high and low voltage switchgear processing, and in particular to a limiting and fixing device for high and low voltage switchgear processing. Background Technology

[0002] The high and low voltage switchgear manufacturing process covers material preparation, structural processing, surface treatment, electrical assembly, functional testing, and final assembly quality inspection.

[0003] In the field of high and low voltage switchgear processing, traditional steel column positioning and fixing methods suffer from bottlenecks such as low efficiency, insufficient precision, surface damage, lack of digitalization (relying on manual experience and data is not traceable), high operational intensity (multi-person collaboration), and high maintenance costs. This leads to a "three lows and three highs" dilemma in production: low efficiency, low precision, low quality, and high cost, high strength, and high energy consumption. Utility Model Content

[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] The limiting and fixing device for processing high and low voltage switchgear according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, the limiting and fixing device for high and low voltage switchgear processing according to an embodiment of this utility model includes:

[0023] Base 1.

[0024] The lateral moving device 2 is mounted on the base 1.

[0025] There are two sets of longitudinal moving devices 3. One set of longitudinal moving devices 3 is set at the moving end of the transverse moving device 2, and the other set of longitudinal moving devices 3 is set on the base 1.

[0026] There are four sets of columns 4, with two sets of columns 4 installed inside each set of longitudinal moving device 3.

[0027] The four sets of columns 4 and the two sets of longitudinal moving devices 3 each have two sets of columns 4 arranged in a rectangular pattern. The fixing components of each set of columns 4 clamp the four corners of the steel column.

[0028] By synchronously adjusting the threaded rods 9 of the four components, the parallelism calibration and overall clamping of the steel column can be achieved.

[0029] The cabinet fixing component 5 is provided on the inner side of the column 4. The cabinet fixing component 5 includes an L-shaped block 6, a clamping block 7, a sliding rod 8 and a threaded rod 9. The L-shaped block 6 is fixed on the inner side of the column 4. The sliding rod 8 is fixed at one end of the L-shaped block 6. The clamping block 7 is slidably connected to the outer wall of the sliding rod 8. The threaded rod 9 is rotatably connected to the clamping block 7. A threaded groove adapted to the threaded rod 9 is opened at one end of the L-shaped block 6. The threaded rod 9 is threadedly connected to the threaded groove of the L-shaped block 6.

[0030] Specifically, the rotating threaded rod 9 is driven by the external hexagonal head 10. The threaded rod 9 engages with the L-shaped block 6 through its threads, generating an axial thrust. Under the action of the thrust, the clamping block 7 moves along the slide rod 8 towards the L-shaped block 6 until the vertical surfaces of the clamping block 7 and the L-shaped block 6 form a clamping force on the steel column. The sliding fit between the slide rod 8 and the clamping block 7, without a self-locking design, ensures a uniform distribution of clamping force and prevents deformation of the steel column.

[0031] In an optional embodiment of this application, one end of the threaded rod 9 is an external hexagonal head 10.

[0032] Specifically, the pre-machined threaded rod 9 with an external hexagonal head 10 is installed onto the clamping block 7 of the cabinet fixing assembly 5, ensuring its flexible rotation. When it is necessary to clamp the high and low voltage switch cabinet or steel column, the operator uses a hexagonal wrench of the appropriate size, inserts it into the external hexagonal head 10, and turns the wrench clockwise. The threaded rod 9 advances within the threaded groove, pushing the clamping block 7 along the slide bar 8 until the clamping block 7 and the L-shaped block 6 together clamp the cabinet or steel column. When it is necessary to loosen, simply turn the wrench counterclockwise.

[0033] In an optional embodiment of this application, the lateral moving device 2 includes a lateral ball screw 11, a lateral slide block, and a lateral motor 12. The lateral slide block is disposed on the base 1. The screw of the lateral ball screw 11 is rotatably connected to the inner wall of the lateral slide block, and the moving end of the lateral ball screw 11 is slidably connected to the inner wall of the lateral slide block. The lateral motor 12 is fixed to the outer wall of the base 1, and the output end of the lateral motor 12 is connected to one end of the lateral ball screw 11.

[0034] Specifically, when it is necessary to adjust the lateral position of the steel column of the high and low voltage switchgear, the operator issues a command through the control system, the lateral motor 12 starts, and drives the screw of the lateral ball screw 11 to rotate. The rotation of the screw is converted into linear motion of the moving end, thereby realizing the movement of the entire device in the lateral direction and adjusting the high and low voltage switchgear steel column to the appropriate processing position.

[0035] In an optional embodiment of this application, the longitudinal moving device 3 includes a longitudinal seat 13, a lead screw bearing seat 14, a longitudinal ball screw 15, a longitudinal slide rail 16, and a longitudinal motor 17. One set of longitudinal seats 13 is disposed on the base 1, and another set of longitudinal seats 13 is disposed on the moving end of the transverse ball screw 11. The lead screw bearing seat 14 is fixed to the surface of the longitudinal seat 13. The screw of the longitudinal ball screw 15 is rotatably connected to the center of the lead screw bearing seat 14. The longitudinal slide rail 16 is fixed to the surface of the longitudinal seat 13. The moving end of the longitudinal ball screw 15 is slidably connected to the track of the longitudinal slide rail 16. The longitudinal motor 17 is fixed to the outer wall of the lead screw bearing seat 14, and the output end of the longitudinal motor 17 is connected to one end of the longitudinal ball screw 15.

[0036] When it is necessary to adjust the longitudinal position of the high and low voltage switchgear steel column, the operator issues a command through the control system, the longitudinal motor 17 starts, and drives the screw of the longitudinal ball screw 15 to rotate. The rotation of the screw is converted into linear motion of the moving end. The moving end slides on the longitudinal slide rail 16 through the longitudinal slider, thereby realizing the movement of the entire device in the longitudinal direction and adjusting the high and low voltage switchgear steel column to the appropriate processing position.

[0037] Specifically, in actual execution, the position of the column 4 is adjusted by the horizontal / vertical moving device 3 so that the steel column is aligned with the clamping area of ​​the clamping block 7 and the L-shaped block 6.

[0038] Clamping Operation: Use a hex wrench to rotate the threaded rod 9, moving the clamping block 7 towards the L-shaped block until the clamping surface can be fitted with a rubber pad to prevent scratches and is tightly against the steel column. Use a torque wrench to control the clamping force. Recommended torque: 15-20 N·m, corresponding to a clamping force of 500-800 N.

[0039] Processing assistance: After the steel columns are fixed, crossbeams can be added between the columns for quick alignment via positioning pin holes. The welding cabinet wall clamps do not affect the welding area. The surface roughness Ra of clamping block 7 and L-shaped block 6 is designed to be ≤3.2μm to provide support for measurement benchmarks, such as laser rangefinders for calibrating column spacing.

[0040] In summary, the limiting and fixing device for high and low voltage switchgear processing according to this utility model embodiment significantly improves the processing efficiency, installation accuracy and surface quality of the cabinet, while supporting digital production and reducing operational intensity and maintenance costs.
