Description

Technical Field

[0001] This utility model relates to the field of secondary terminal block installation technology, and in particular to a positioning and alignment device for a secondary terminal block. Background Technology

[0002] Secondary terminal blocks refer to the wiring terminals used in electrical equipment or electrical control systems for auxiliary circuits (such as control, signal transmission, measurement, etc.). Compared with primary terminal blocks (used for main power transmission wiring), secondary terminal blocks usually handle lower voltages and currents. During the installation of electrical equipment, it is necessary to ensure that the terminal blocks are accurately aligned, especially when they need to be installed in the center of the electrical equipment or mounting panel. Therefore, a positioning and alignment device is required to facilitate wiring and subsequent maintenance.

[0003] However, the positioning and alignment device for secondary terminal blocks in the existing technology is prone to causing the secondary terminal blocks to shift during the positioning process. Furthermore, when installed on electrical equipment and mounting panels, the device itself may shift, which could also cause the secondary terminal blocks to shift.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Utility Model Content

[0005] This utility model provides a head drive mechanism for a residual electrode feeder to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a head drive mechanism for a residual electrode feeder, comprising a mounting plate, wherein two fixing rods are symmetrically fixed at the front and rear ends of the mounting plate at the middle position, a second spring is fixed inside the fixing rod, and a positioning rod is fixed at one end of the second spring, extending through and to the outside of the fixing rod. Through slots are provided at the four corners inside the mounting plate, and a centering mechanism is installed inside the through slots. Positioning blocks are provided at both the front and rear ends of both sides of the mounting plate, and a positioning component is installed between the mounting plate and the positioning blocks.

[0007] Furthermore, the centering mechanism includes clamping blocks disposed at the four corners inside the mounting plate. Connecting rods are rotatably connected to both outer sides of the clamping blocks. One side of the connecting rod passes through and extends into the through groove and is rotatably connected to a limiting slider. A guide slide rod is connected through the limiting slider. Mounting blocks are fixed to both sides of the guide slide rod inside the through groove. A first spring is fixed to one side of the limiting slider and sleeved on the outer layer of the guide slide rod.

[0008] Furthermore, the positioning component includes two knobs rotatably connected to the front and rear ends of the upper surface of the mounting plate. The bottom of each knob is fixed with a rotating shaft that penetrates and extends into the interior of the mounting plate. A second bevel gear is sleeved on the outer layer of the rotating shaft. Two first bevel gears rotatably connected to the interior of the mounting plate are symmetrically arranged on both sides below the second bevel gear.

[0009] Furthermore, a lead screw is fixed to one side of the first bevel gear, and a telescopic rod that is slidably connected inside the mounting plate is sleeved on the outer layer of the lead screw. One side of the telescopic rod passes through and extends to the outside of the mounting plate.

[0010] Furthermore, positioning blocks are fixed to the sides of both the telescopic rod and the positioning rod, and anti-slip pads are fixed to the inner side of the positioning blocks.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] 1. This utility model is equipped with a centering mechanism. When installing secondary terminal blocks, the terminal blocks are inserted into the four clamping blocks. By pressing the clamping blocks into the through slot, it is easy to place terminal blocks of different sizes between the four clamping blocks. As the external force disappears, the limiting slider is rebounded by the first spring to form a reset effect. The connecting rod moves with the limiting slider, thereby driving the clamping blocks to move to the middle position inside the mounting plate, thus forming a centering clamping effect and ensuring that terminal blocks of different sizes are located in the middle position.

[0013] 2. This utility model includes a positioning component. By rotating the knob in conjunction with the first and second bevel gears, the lead screw is driven to rotate. The rotation of the lead screw drives the telescopic rod to move, thereby adapting to the length of the mounting panel. At the same time, the positioning rod is pulled to adapt to the width of the mounting panel. The two work together to ensure that the mounting plate is located in the center of the terminal block mounting panel. In conjunction with the centering mechanism, the terminal block is located in the center of the mounting plate. The combination of these two components ensures that the terminal block is always located in the center of the mounting panel, which makes it easier to install and fix the terminal block.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: As Figure 4-5 As shown, a positioning and alignment device for a secondary terminal block includes a mounting plate 1. Two fixing rods 3 are symmetrically fixed at the front and rear ends of the mounting plate 1 at the middle position. A second spring 20 is fixed inside the fixing rod 3. A positioning rod 2 that penetrates through and extends to the outside of the fixing rod 3 is fixed at one end of the second spring 20. The positioning rod 2 is driven by the second spring 20 to achieve a reset effect, thereby clamping the mounting panel. Positioning blocks 5 are provided at both the front and rear ends of the two sides of the mounting plate 1. A positioning component 4 is installed between the mounting plate 1 and the positioning blocks 5.

[0022] The positioning component 4 includes two knobs 7 rotatably connected to the front and rear ends of the upper surface of the mounting plate 1. The bottom of the knobs 7 is fixed with a rotating shaft 17 that passes through and extends into the interior of the mounting plate 1. A second bevel gear 19 is sleeved on the outer layer of the rotating shaft 17. Two first bevel gears 16 rotatably connected to the interior of the mounting plate 1 are symmetrically arranged on both sides below the second bevel gear 19. A lead screw 15 is fixed on one side of the first bevel gear 16. A telescopic rod 18 slidably connected to the interior of the mounting plate 1 is sleeved on the outer layer of the lead screw 15.

[0023] By adjusting the lengths of the positioning rod 2 and the telescopic rod 18, the two work together to ensure that the mounting plate 1 is located at the center of the mounting panel. One side of the telescopic rod 18 extends through and to the outside of the mounting plate 1. Positioning blocks 5 are fixed to the sides of both the telescopic rod 18 and the positioning rod 2. Anti-slip pads are fixed to the inner side of the positioning blocks 5. The mounting panel is clamped and positioned by the positioning blocks 5.

[0024] Rotating knob 7 drives shaft 17 to rotate. The rotation of shaft 17, in conjunction with the second bevel gear 19 and the first bevel gear 16, drives two lead screws 15 to rotate. The rotation of lead screws 15 drives telescopic rod 18 to move, thus adapting to the length of the mounting panel. At the same time, it pulls positioning rod 2 to extend outward, thus adapting to the width of the mounting panel. The two work together to ensure that mounting plate 1 is located in the center of the mounting panel.

[0025] Example 2: Figure 1-3 As shown, the embodiment is a positioning and alignment device for a secondary terminal block. A through groove 8 is provided at each of the four corners inside the mounting plate 1. An alignment mechanism 6 is installed inside the through groove 8. The alignment mechanism 6 includes clamping blocks 9 located at the four corners inside the mounting plate 1. Connecting rods 12 are rotatably connected to both sides of the clamping blocks 9. One side of the connecting rod 12 passes through and extends into the through groove 8 and is rotatably connected to a limit slider 11.

[0026] The limiting slider 11 has a guide slide rod 13 that runs through it. Both sides of the guide slide rod 13 are fixed with mounting blocks 14 inside the through groove 8. One side of the limiting slider 11 is fixed with a first spring 10 that is sleeved on the outer layer of the guide slide rod 13. The limiting slider 11 moves under the rebound force of the first spring 10, and moves with the connecting rod 12 to drive the clamping block 9 to move. The movement of the clamping block 9 is used to clamp and fix the terminal block.

[0027] After the mounting plate 1 is installed on the surface of the mounting panel, the clamping block 9 is pushed to move into the through slot 8 and the terminal block is placed inside the mounting plate 1. As the external force is eliminated, the limiting slider 11 moves under the rebound force of the first spring 10. During the movement of the limiting slider 11, the connecting rod 12 moves. As the connecting rod 12 moves, the clamping block 9 moves to the middle position inside the mounting plate 1. The four clamping blocks 9 move synchronously, thereby fixing the terminal block inside the mounting plate 1 at the center position, which facilitates the quick and accurate installation and fixing of the terminal block to the center position of the mounting panel.

[0028] The working process and principle of this utility model are as follows:

[0029] Step 1: Rotate knob 7 to drive shaft 17 to rotate. The rotation of shaft 17, in conjunction with the second bevel gear 19 and the first bevel gear 16, drives two lead screws 15 to rotate. The rotation of lead screws 15 drives telescopic rod 18 to move, thus adapting to the length of the mounting panel. At the same time, it pulls positioning rod 2 to extend outward, thus adapting to the width of the mounting panel. The two work together to ensure that mounting plate 1 is located in the center of the mounting panel.

[0030] Step 2: After the mounting plate 1 is installed on the surface of the mounting panel, push the clamping block 9 to move into the through groove 8 and place the terminal block inside the mounting plate 1. As the external force is eliminated, the limiting slider 11 moves under the rebound force of the first spring 10. During the movement of the limiting slider 11, the connecting rod 12 moves. As the connecting rod 12 moves, the clamping block 9 moves towards the middle position inside the mounting plate 1. The four clamping blocks 9 move synchronously, thereby fixing the terminal block inside the mounting plate 1 at the center position, which facilitates the quick and accurate installation and fixing of the terminal block to the center position of the mounting panel.

[0031] In summary, the positioning component 4 is used to fix the mounting plate 1 to the surface of the mounting panel and position it at the center of the mounting panel. Then, the terminal block is inserted into the mounting plate 1. The centering mechanism 6 positions the terminal block and positions it at the center of the mounting plate 1. The two work together to position the terminal block at the center of the mounting panel, which facilitates quick positioning and centering installation.

[0032] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
