Description

Technical Field

[0001] The utility model belongs to the technical field of electrical equipment, and particularly relates to a clamping device for electrical equipment. Background Art

[0002] With the rapid development of industrial automation technology, the manufacturing and processing processes of electrical equipment have increasingly higher requirements for precision and efficiency. Loop resistors are often used in electrical equipment. However, the structures and sizes of loop resistors in different electrical equipment are different. Therefore, it is necessary to develop a device that can clamp loop resistor structures of different sizes.

[0003] Currently, the Chinese utility model patent announced as CN218285423U discloses an electrical equipment maintenance clamping tool, which is provided with an operation board. A slide rail is installed on the top of the operation board, and a fixed block is slidably connected to the top of the slide rail. The fixed block is of a groove structure. By rotating the locking knob, the lifting block is adjusted in height at the lifting rod, driving the operation board to change in height, which is convenient for improving the comfort of the operator. The bottom stabilizing plate is abutted against the ground, and during the maintenance work, the shock-absorbing base and the shock-absorbing spring are used to improve stability.

[0004] When this patent is in use, although the height of the operation board can be adjusted, the clamping device can only be adjusted horizontally and cannot be adjusted rotationally. During the manufacturing and maintenance of electrical equipment, operations are often required in multiple directions, resulting in the need for workers to repeatedly adjust their postures. Content of the Utility Model

[0005] The purpose of the utility model is to provide a clamping device for electrical equipment, which solves the problem that an existing electrical equipment maintenance clamping tool cannot be adjusted rotationally. During the manufacturing and maintenance of electrical equipment, operations are often required in multiple directions, resulting in the need for workers to repeatedly adjust their postures.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions. A clamping device for electrical equipment includes a bottom plate, an elevating mechanism is arranged on the bottom plate, an operation table is arranged on the elevating mechanism, a clamping mechanism is arranged on the operation table, and a loop resistor is fixedly clamped on the clamping mechanism;

[0007] The clamping mechanism includes a slide rail, a lead screw, a first motor, a sliding block, a mounting block, a rotating assembly, a turntable and a clamping chuck. The slide rail is fixedly connected to the operation table, the lead screw is rotatably arranged on the operation table, the first motor is arranged at one end of the lead screw, the sliding block is slidably connected to the slide rail, the mounting block is threadedly rotatably connected to the lead screw, the rotating assembly is arranged on the mounting block, the turntable is fixedly connected to the rotating assembly, and the clamping chuck is arranged on the turntable.

[0008] With the above technical solution, by setting a bottom plate, a lifting mechanism, a working platform, a clamping mechanism and a loop resistance, during use, first, the bottom plate can install and fix the lifting mechanism, and then the lifting mechanism can drive the working platform to move up and down, so that the height of the working platform conforms to the height of the staff, making it convenient for the staff to operate. Then, the clamping mechanism can clamp and fix the loop resistance. When the staff needs to work in multiple directions, only need to drive the loop resistance to rotate through the clamping mechanism, avoiding the staff from repeatedly adjusting their own postures. The clamping mechanism includes a slide rail, a lead screw, a first motor, a sliding block, a mounting block, a rotating component and a clamping chuck. During use, first, the first motor can drive the first lead screw to rotate. Since the mounting block is threadedly connected to the lead screw, the rotating component and the clamping chuck on the mounting block can be moved until the clamping chuck moves to the position of the staff. Among them, through the cooperation of the slide rail and the sliding block, the movement of the rotating component can be limited. When machining in multiple directions is required, only need to drive the clamping chuck to rotate through the rotating component, avoiding the staff from repeatedly adjusting their own positions.

[0009] Further: The rotating component includes a mounting plate, a rotating sleeve, a first gear, a rotating rod, a second gear, a third gear, a connecting plate, a fourth gear and a second motor.

Then, the connecting plate can install the rotating rod and the second motor. Then, the second motor can drive the fourth gear to rotate, and then drive the third gear to rotate, and then drive the rotating rod and the second gear to rotate. Since the second gear is meshed with the first gear, the first gear can drive the rotating sleeve to rotate. Since the clamping chuck is fixed in the rotating sleeve, the loop resistance in the clamping chuck can be rotated, avoiding the staff from repeatedly adjusting their own postures.

[0011] Furthermore: The lifting mechanism includes scissor hinge plates, connecting rods, and cylinders. One end of each scissor hinge plate is disposed on the bottom plate, and the other end is disposed on the lower surface of the working table. There are two scissor hinge plates which are symmetrically arranged. The connecting rods are disposed between the two scissor hinge plates. The cylinders are disposed on the bottom plate, and the telescopic shafts of the cylinders are connected to the connecting rods.

[0012] With the above technical solution, by providing scissor hinge plates, connecting rods, and cylinders, during use, first, one end of each scissor hinge plate is disposed on the bottom plate, and the other end is disposed on the working table. The connecting rods connect the two scissor hinge plates. The cylinders drive the scissor hinge plates to rotate, thereby causing the working table to move up and down, enabling the position of the loop resistance to adapt to the height of the staff.

[0013] Furthermore: Limiting grooves are formed on the slide rails, and the sliding blocks slide in the limiting grooves.

[0014] With the above technical solution, by providing the limiting grooves, during use, the limiting grooves can restrict the sliding blocks on the slide rails, making the movement of the sliding blocks more stable.

[0015] Furthermore: Universal wheels are disposed on the lower surface of the bottom plate. There are four universal wheels which are symmetrically arranged.

[0016] With the above technical solution, by providing the universal wheels, during use, first, the universal wheels can facilitate the movement of the bottom plate, improve the mobility of the equipment, and make it more convenient to use.

[0017] Furthermore: Through grooves are formed on the working table, and the through grooves are used to provide a path for the sliding of the second motor.

[0018] With the above technical solution, by providing the through grooves, when the mounting plate moves, the second motor moves synchronously with the mounting plate. At this time, the through grooves can provide a path for the movement of the second motor.

[0019] Furthermore: Pulleys are disposed at both ends of the scissor hinge plates, and the lower surface of the working table and the upper surface of the bottom plate can provide limits for the sliding of the pulleys.

[0020] With the above technical solution, by providing the pulleys, when the scissor hinge plates rotate, the pulleys can slide on the lower surface of the working table and the upper surface of the bottom plate, providing conditions for the rotation of the scissor hinge plates.

[0021] Furthermore: Mounting grooves for providing mounting positions for the first motor are formed on the working table.

[0022] With the above technical solution, by providing the mounting grooves, during use, the mounting grooves can provide mounting positions for the first motor, facilitating the fixation of the first motor.

[0023] In summary, the utility model has the following beneficial effects:

[0024] By setting the clamping mechanism, during use, first, the first motor can drive the first lead screw to rotate. Since the mounting block is in threaded rotational connection with the lead screw, the rotating assembly and the clamping chuck on the mounting block can be moved until the clamping chuck moves to the position of the operator. Among them, through the combined use of the slide rail and the sliding block, the movement of the rotating assembly can be limited. When processing in multiple directions is required, it is only necessary to rotate the clamping chuck by the rotating assembly, avoiding the operator from repeatedly adjusting their own position.

[0025] By setting the rotating assembly, during use, the mounting plate is fixed on the upper surfaces of the mounting block and the sliding block. Then, the connecting plate can mount the rotating rod and the second motor. Then, the second motor can drive the fourth gear to rotate, thereby driving the third gear to rotate, and then the rotating rod and the second gear to rotate. Since the second gear is in meshing connection with the first gear, the first gear can drive the rotating sleeve to rotate. Since the clamping chuck is fixed in the rotating sleeve, the loop resistance in the clamping chuck can be rotated, avoiding the operator from repeatedly adjusting their own posture.

[0026] Based on the above improvement points, the overall technical effect achieved by this device is that when clamping an electrical device, it can rotate the electrical device and operate in multiple directions of the electrical device, without the operator frequently adjusting their own posture.
