Description

Technical Field

[0001] The utility model belongs to the technical field of electrical assembly, and particularly relates to a liftable electrical cabinet workbench. Background Art

[0002] A liftable electrical cabinet workbench is a workbench designed specifically for electrical equipment assembly. It integrates a work plate and adjustable height functions. This type of workbench usually has a stable structure and is equipped with an electric, pneumatic or hydraulically driven lifting system. The height of the work plate can be accurately adjusted to accommodate workers of different body sizes and the optimal working height requirements of different electrical cabinets during the assembly process. In actual applications, this type of workbench can not only improve work efficiency and reduce physical fatigue of workers caused by long-term bending or raising arms, but also ensure the accuracy and safety of electrical cabinet assembly. The work plate may also be equipped with a device specifically for fixing and positioning electrical components to facilitate workers to perform orderly and efficient assembly operations.

[0003] The existing liftable electrical cabinet workbench realizes the lifting of the workbench on the electrical cabinet by a push rod, and clamps and processes the two sides of the workpiece by driving two clamping plates. Since the upper end of the workpiece is not limited by the clamping, the workpiece may shift or shake during the processing, resulting in a decrease in processing accuracy and even affecting the processing quality. It may also cause the workpiece to accidentally detach from the clamping device, causing a safety accident. Utility Model Content

[0004] In view of this, the utility model aims to address the deficiencies in the prior art and provides a liftable electrical cabinet workbench. By limiting and clamping the upper end of the workpiece, it can ensure that the workpiece maintains a stable position during the processing, reduce deviation and shaking, improve processing accuracy and quality, and prevent the workpiece from accidentally detaching from the clamping device, reducing the occurrence of safety accidents and protecting the safety of operators.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a liftable electrical cabinet workbench, including a cabinet body, supporting feet are respectively welded and fixed at the four corners of the lower end of the cabinet body, a partition is arranged inside the cabinet body, two cabinet doors are hinged on the front side of the cabinet body through hinges, handles are arranged on the front sides of the two cabinet doors, and two observation windows are arranged on the front sides of the two cabinet doors, electric push rods are respectively arranged at the four corners of the upper end of the cabinet body, a lifting platform is arranged between the upper ends of the telescopic ends of the four electric push rods, and a clamping mechanism is arranged inside the lifting platform, the clamping mechanism includes two clamping plates corresponding to the left and right positions slidably arranged inside the lifting platform, a rotating seat is arranged at the lower ends of the two clamping plates, and two connecting frames are rotatably connected inside the two rotating seats, and a rotating frame is rotatably connected between two connecting frames adjacent to the left and right, and a connecting plate is arranged at the lower end of the lifting platform, and two connecting plates are rotatably arranged inside the connecting plate. The two cams have the form of a screw rod, the two screw rods have opposite thread directions, the two rotating frames are respectively threadedly connected to adjacent screw rods, the two clamping plates are respectively provided with a downward pressing fixing mechanism, and the bottom wall of the connecting plate is provided with an electric drive unit that drives the two screw rods to rotate, the downward pressing fixing mechanism comprises a rectangular plate respectively arranged on the inner side surfaces of the two clamping plates, the internal threaded holes opened in the two rectangular plates are respectively threadedly connected to screw rods, the two clamping plates are respectively slidably connected to pressure plates on the inner side surfaces of the two clamping plates, the two screw rods are respectively threadedly connected to the upper ends of adjacent pressure plates, the upper ends of the two screw rods are both provided with auxiliary rotating components, the auxiliary rotating components comprise knobs respectively arranged on the upper ends of the two screw rods, the outer arc surfaces of the two knobs are both provided with anti-slip protrusions, the electric drive unit comprises a dual-axis motor arranged on the bottom wall of the connecting plate, and the output shafts on the front and rear sides of the dual-axis motor are respectively connected to the relative inner ends of adjacent screw rods through couplings.

[0006] As a further improvement of the present invention, a control panel is provided at the upper left end of the cabinet, and the electric push rod and the dual-axis motor are both electrically connected to the control panel.

[0007] As a further improvement of the utility model, evenly distributed anti-slip protrusions are respectively arranged on the inner side surfaces of the clamping plates.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] Firstly, by placing the workpiece on the lifting platform so that it is located between the two clamping plates, and then turning on the dual-axis motor, the output shaft drives the screw rods on both sides to rotate. Since the screw threads on both sides are in opposite directions, the rotating frames move away from each other, and the internal connecting frame rotates and contracts, driving the clamping plates on the rotating seat to move closer to each other to clamp the left and right sides of the workpiece. Then, by rotating the knobs on both sides, the screw rod rotates, driving the pressure plate to move downward to achieve the clamping limit of the upper end of the workpiece. By limiting the upper end of the workpiece, it can ensure that the workpiece maintains a stable position during the processing, reduce deviation and shaking, improve processing accuracy and quality, and prevent the workpiece from accidentally detaching from the clamping device, reduce the occurrence of safety accidents, and protect the safety of operators.

[0010] Secondly, the anti-skid protrusion 2 can prevent the person's hand from slipping when the person rotates the knob, making it easier for the person to rotate the knob.

[0011] Thirdly, by controlling the operation of the electric push rod, the telescopic end drives the lifting platform to move, and the height of the lifting platform can be quickly and stably adjusted.

[0012] Fourthly, the anti-slip protrusion on the clamping plate can increase the friction between the clamping plate and the workpiece, avoiding displacement and making the workpiece clamped more stably. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to better understand the present invention, the content of the present invention is further clearly described below in conjunction with the embodiments, but the protection content of the present invention is not limited to the following embodiments. In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0020] like Figure 1 , 2 As shown in Figures 3 and 4, a liftable electrical cabinet workbench comprises a cabinet body 101, supporting feet 103 are respectively welded and fixed to the four corners of the lower end of the cabinet body 101, a partition 106 is arranged inside the cabinet body 101, two cabinet doors 102 are hingedly connected to the front side of the cabinet body 101 through hinges, handles are arranged on the front sides of the two cabinet doors 102, and two observation windows are arranged on the front sides of the two cabinet doors 102, electric push rods 104 are respectively arranged at the four corners of the upper end of the cabinet body 101, a lifting platform 105 is arranged between the upper ends of the telescopic ends of the four electric push rods 104, and a clamping mechanism is arranged inside the lifting platform 105.

[0021] like Figure 1 , 2 As shown in 4, the clamping mechanism includes two clamping plates 201 slidably arranged at two left and right positions inside the lifting platform 105, and the lower ends of the two clamping plates 201 are each provided with a rotating seat 202. The interiors of the two rotating seats 202 are both rotatably connected to two connecting frames 205, and a rotating frame 207 is rotatably connected between the two connecting frames 205 adjacent to the left and right. The lower end of the lifting platform 105 is provided with a connecting plate 208, and the interior of the connecting plate 208 is rotatably provided with two screw rods 206. The thread directions of the two screw rods 206 are opposite, and the two rotating frames 207 are respectively threadedly connected to the adjacent screw rods 206. The opposite inner side surfaces of the two clamping plates 201 are respectively provided with downward pressing fixing mechanisms, and the bottom wall of the connecting plate 208 is provided with an electric driving unit for driving the two screw rods 206 to rotate. The fixing mechanism includes rectangular plates 304 respectively arranged on the relative inner side surfaces of the two clamping plates 201, and screws 303 are respectively threadedly connected in the internal threaded holes opened inside the two rectangular plates 304. Pressure plates 301 are respectively slidably connected on the relative inner side surfaces of the two clamping plates 201. The two screws 303 are respectively threadedly connected to the upper ends of adjacent pressure plates 301. The upper ends of the two screws 303 are both provided with auxiliary rotating components. The auxiliary rotating components include knobs 302 respectively arranged on the upper ends of the two screws 303, and anti-slip protrusions 305 are respectively arranged on the outer arc surfaces of the two knobs 302.
