Low-voltage power distribution control cabinet processing fixing tool

Abstract

This utility model discloses a fixing fixture for processing low-voltage power distribution control cabinets, relating to the field of control cabinet processing technology. The fixture includes a base, a supporting vertical plate fixedly installed at the rear top of the base, a cabinet shell fitted onto the front end of the base, a supporting unit at the top of the base, and a contact unit on the inner side of the supporting vertical plate. This utility model uses an electrically operated telescopic column to activate and extend the connecting cylinder. When the connecting cylinder extends or retracts, it causes the surrounding push-pull rods to change their tilt angle, thereby causing four sets of contact plates to contact the inner walls of the cabinet shell. This forms a supporting and fixing mechanism around the cabinet shell, increasing its rigidity and preventing deformation or denting during processing. The use of rubber pads further increases the friction between the contact plates and the inner walls of the cabinet shell, improving contact stability and ultimately enhancing processing quality.

Description

Technical Field

[0001] This utility model relates to the field of control cabinet processing technology, specifically to a fixed tooling for processing low-voltage power distribution control cabinets. Background Technology

[0002] Low-voltage switchgear is an integrated device used in power systems for power distribution, control, protection, and monitoring. It is widely used in power plants, substations, factories, mines, high-rise buildings, and commercial complexes, and is a crucial piece of equipment at the end of the power system. The housing of the low-voltage switchgear requires clamping and fixing during processing to ensure stability.

[0003] In the prior art, a Chinese patent document with publication number CN209903171U and publication date of January 7, 2020, was proposed to solve the above-mentioned technical problems. The technical solution disclosed in this patent document is as follows: a fixing fixture for processing the cabinet of a frequency converter control cabinet, including a support plate, a connecting rod, an electric cylinder, and a shock-absorbing base. The connecting rod is installed below the support plate, the electric cylinder is installed below the connecting rod, and the shock-absorbing base is fixed below the electric cylinder. The shock-absorbing base includes a housing, a fixing sleeve, a telescopic rod, a spring, and a lifting plate. The fixing sleeve is fixed inside the housing, the telescopic rod is arranged above the fixing sleeve, the spring is arranged outside the fixing sleeve and the telescopic rod, and the lifting plate is fixed above the telescopic rod.

[0004] To solve the problem of fixing the control cabinet during processing, the existing technology involves rotating an adjustment knob, which drives the first and second threaded rods to rotate. Since the threads of the first and second threaded rods are in opposite directions, the two moving blocks move closer to each other. The moving blocks then drive the clamping plates to move closer to each other, thus contacting and fixing the control cabinet body. However, this fixing fixture can only clamp the two sides of the cabinet body. Because the cabinet body is a shell-shaped structure with a hollow interior, the cabinet body will deform during processing. Utility Model Content

[0005] The purpose of this utility model is to provide a fixed tooling for processing low-voltage power distribution control cabinets, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A fixing fixture for processing a low-voltage power distribution control cabinet includes a base, a supporting vertical plate fixedly installed at the top rear end of the base, and a cabinet shell sleeved at the front end of the base.

[0008] The base is provided with a support unit at its top, and the support vertical plate is provided with an abutment unit on its inner side.

[0009] The abutment unit includes a connecting column fixedly installed on the inner side of the support vertical plate, and a cross support frame fixedly installed on the other end of the connecting column. The bottom end of the cross support frame is fixedly installed on the top of the base.

[0010] The support unit includes fixed crossbars that are fixedly installed on both sides of the top of the base.

[0011] A further improvement of this utility model is that: a limiting groove is provided on all four sides of the cross support frame, a sliding rod is fixedly installed inside the limiting groove, and an electric telescopic column is fixedly installed at the middle position of the inner side of the cross support frame. The model of the electric telescopic column is: ANT-03-300N.

[0012] A further improvement of this utility model is that a connecting cylinder is fixedly connected to the other end of the electric telescopic column, and a connecting arc block is fixedly installed on all four sides of the connecting cylinder.

[0013] A further improvement of the present invention is that: a push-pull rod is rotatably connected to both sides of the first connecting arc block, and a second connecting arc block is rotatably connected to the other end of the push-pull rod.

[0014] A further improvement of this utility model is that: a contact plate is fixedly installed on the top of the second connecting arc block, and a rubber pad is fixedly connected to the outer surface of the contact plate. The rubber pad can increase the friction between the contact plate and the cabinet shell, thereby promoting processing stability.

[0015] A further improvement of this utility model is that a slider is fixedly installed on one inner end of the contact plate, and the slider is slidably sleeved on the outer surface of the slide rod. The slide rod can limit the movement of the contact plate.

[0016] A further improvement of this utility model is that: a left clamping ring is fixedly installed at both the front and rear ends of the outer surface of the fixed crossbar on the left side, and a right clamping ring is fixedly installed at both the front and rear ends of the outer surface of the fixed crossbar on the right side. The left and right clamping rings can provide auxiliary support and fixation for the processing of the cabinet shell.

[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0018] 1. This utility model provides a fixing fixture for processing low-voltage power distribution control cabinets. By setting a left clamping ring and a right clamping ring, the cabinet shell to be processed is inserted between the two. The two sets of left clamping rings and right clamping rings support and clamp it, thereby achieving the effect of initial fixing and support.

[0019] 2. This utility model provides a fixed fixture for processing low-voltage power distribution control cabinets. By setting an electric telescopic column, the connecting cylinder is activated to extend and retract. When the connecting cylinder extends and retracts, the surrounding push-pull rods change their tilt angle, thereby causing four sets of abutment plates to abut against the inner wall of the cabinet shell. This forms a support and fixation around the inside of the cabinet shell, increasing its rigidity and preventing the cabinet from denting or deforming during processing. The rubber pads further increase the friction between the abutment plates and the inner wall of the cabinet shell, further promoting contact stability and thus improving the processing quality.

[0026] 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.

[0027] Example 1

[0028] like Figure 1-5As shown, this utility model provides a fixing fixture for processing low-voltage power distribution control cabinets. The fixing fixture 1 includes a base 2, a supporting vertical plate 3 fixedly installed at the top rear end of the base 2, a cabinet shell 4 sleeved at the front end of the base 2, a supporting unit provided at the top of the base 2, and an abutment unit provided on the inner side of the supporting vertical plate 3. The supporting unit includes a fixing crossbar 21 fixedly installed on both sides of the top of the base 2. A left clamping ring 22 is fixedly installed at both the front and rear ends of the outer surface of the left fixing crossbar 21, and a right clamping ring 23 is fixedly installed at both the front and rear ends of the outer surface of the right fixing crossbar 21.

[0029] Furthermore, the cabinet shell 4 to be processed is inserted between the left clamping ring 22 and the right clamping ring 23, and supported and clamped by the two sets of left clamping rings 22 and right clamping rings 23 for initial fixation.

[0030] Example 2

[0031] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the contact unit includes a connecting column 31 fixedly installed on the inner side of the supporting vertical plate 3, a cross support frame 32 fixedly installed on the other end of the connecting column 31, the bottom end of the cross support frame 32 fixedly installed on the top of the base 2, limit grooves 33 are formed on all four sides of the cross support frame 32, a sliding rod 34 is fixedly installed inside the limit groove 33, and an electric telescopic column 35 is fixedly installed at the middle position of the inner side of the cross support frame 32. A connecting cylinder 36 is fixedly connected to the other end of the column 35. Connecting arc blocks 37 are fixedly installed around the circumference of the connecting cylinder 36. Push-pull rods 38 are rotatably connected to both sides of the connecting arc blocks 37. Connecting arc blocks 39 are rotatably connected to the other end of the push-pull rods 38. A contact plate 310 is fixedly installed on the top of the connecting arc blocks 39. A rubber pad 311 is fixedly connected to the outer surface of the contact plate 310. A slider 312 is fixedly installed on one inner end of the contact plate 310. The slider 312 is slidably sleeved on the outer surface of the slide rod 34.

[0032] Furthermore, the activation of the electric telescopic column 35 causes the connecting cylinder 36 to extend and retract accordingly. When the connecting cylinder 36 extends and retracts, it causes the surrounding push-pull rods 38 to change their tilt angle, thereby causing the four sets of abutment plates 310 to abut against the inner wall of the cabinet shell 4, forming a support and fixation around the inside of the cabinet shell 4, increasing its rigidity and preventing the cabinet from denting or deforming during processing. In conjunction with the rubber pads 311, the friction between the abutment plates 310 and the inner wall of the cabinet shell 4 can be increased, further promoting the stability of the abutment.

[0033] The solution uses a PLC as the core control component. The PLC establishes a connection with the electric telescopic column 35 through RS-485 communication. When the electric telescopic column 35 needs to be started, the PLC sends a start command to the electric telescopic column 35 to start it.

[0034] The working principle of the fixed fixture used for processing the low-voltage power distribution control cabinet will be explained in detail below.

[0035] like Figure 1-5 As shown, during use, the cabinet shell 4 to be processed is inserted between the left clamping ring 22 and the right clamping ring 23. The two sets of left clamping rings 22 and right clamping rings 23 support and clamp it for initial fixation. At this time, the four sets of abutment plates 310 are located inside the cabinet shell 4. Then, the connection cylinder 36 is extended and retracted by the start of the electric telescopic column 35. When the connection cylinder 36 extends and retracts, it causes the surrounding push-pull rods 38 to change the tilt angle, thereby causing the four sets of abutment plates 310 to abut against the inner wall of the cabinet shell 4. This forms a support and fixation around the inside of the cabinet shell 4, increasing its rigidity and preventing the cabinet from denting and deforming during processing. The rubber pads 311 can increase the friction between the abutment plates 310 and the inner wall of the cabinet shell 4, further promoting the stability of the abutment.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
