Description
Technical Field
[0001] This utility model relates to the field of terminal block assembly technology, and more specifically, to a terminal block assembly support workpiece. Background Technology
[0002] Terminal blocks are insulating components that support multiple or more sets of mutually insulated terminal assemblies and are used for fixing and supporting parts. Their function is to connect the wiring of devices inside and outside the panel, facilitating signal transmission, making wiring neat and maintenance convenient. Terminal blocks mainly consist of an insulating shell, metal conductive plates, screws or spring clamps, etc., used to achieve reliable connection and disconnection between wires. During terminal block assembly, to facilitate the installation of metal conductive plates and other components inside the insulating shell, a supporting workpiece is usually used to clamp and fix the plastic shell, keeping the insulating shell stable during terminal block assembly. When assembling different types of terminal blocks, the assembly port orientation varies. Some terminal blocks have two or more assembly ports. When assembling such terminal blocks, workers need to adjust the position of the terminal block and change the orientation of the assembly ports to facilitate assembly. However, adjusting the terminal block requires first releasing the clamps and then clamping it again, which is time-consuming and affects assembly efficiency. Therefore, we propose a terminal block assembly supporting workpiece. Utility Model Content
[0003] The purpose of this utility model is to provide a terminal block assembly support workpiece to solve the problem mentioned in the background art that the terminal block requires a long time to adjust its position, which affects the efficiency of terminal block assembly.
[0004] To address the aforementioned problems, the present invention aims to provide a terminal block assembly support workpiece, comprising a mounting shell. The upper side of the mounting shell is used to place the terminal block. An installation groove is formed inside the mounting shell, and a clamping mechanism is provided inside the installation groove. Two adjustment mechanisms are provided on both sides of the clamping mechanism, extending through the installation groove. When the terminal block is placed on the mounting shell, the terminal block is located between the two adjustment mechanisms. The clamping mechanism drives the two adjustment mechanisms to move towards the terminal block to clamp it. After the clamping mechanism drives the adjustment mechanisms to clamp the terminal block, the adjustment mechanisms drive the terminal block to rotate. The adjustment mechanism includes a reset assembly, on which a servo motor is provided. The output shaft of the servo motor is connected to a positioning plate via a coupling. The rotating output shaft of the servo motor drives the positioning plate to rotate, and the shape of the positioning plate matches the cross-section of the terminal block.
[0005] As a further improvement to this technical solution, the clamping mechanism includes two movable plates slidably connected inside the mounting groove, with the ends of the two movable plates far apart from each other passing through the mounting groove and extending outwards.
[0006] As a further improvement to this technical solution, a placement slot is provided at one end of the movable plate inside the mounting slot. The placement slot is provided with two electric telescopic rods. One end of the electric telescopic rod is fixedly connected to the inside of the mounting slot, and the piston rod end of the electric telescopic rod is fixedly connected to the inner wall of the placement slot. During the extension and retraction process, the piston rods of the two electric telescopic rods drive the movable plate to move along the axial direction of the mounting slot.
[0007] As a further improvement to this technical solution, a positioning shell is fixedly connected to one end of the movable plate located outside the mounting groove. The movable plate drives the positioning shell to move during the movement process, and a moving groove is provided at the upper end of the positioning shell.
[0008] As a further improvement to this technical solution, the reset assembly includes an extension plate slidably connected inside the moving slot, the upper end of the extension plate passing through the moving slot and extending outwards, and the servo motor being fixedly connected to the side of the extension plate away from the mounting shell.
[0009] As a further improvement to this technical solution, a number of tension springs are fixedly connected between the bottom of the extension plate and the inner wall of the moving groove. When the tension springs are in a stretched state, their contraction causes the extension plate to move downward along the axial direction of the moving groove.
[0010] As a further improvement to this technical solution, a mounting bracket is fixedly connected to the lower side of the mounting shell, the mounting bracket supports and fixes the mounting shell, and two support rollers are rotatably connected to the opposite side walls of the positioning shell near the bottom. Limit grooves are opened on the upper side of the mounting bracket near both ends, and the bottom of the support rollers rolls in contact with the bottom wall of the limit groove.
[0011] As a further improvement to this technical solution, the upper sides of the mounting shell and the two movable plates are inclined surfaces, and the bottom of the positioning plate slides along the inclined surfaces during rotation.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This terminal block assembly supports the workpiece. The clamping mechanism drives the adjustment mechanism to move and clamp and fix the terminal block on the mounting shell. When it is necessary to adjust the orientation of the terminal block assembly port, the output shaft of the servo motor rotates and drives the positioning plate to rotate. During the rotation of the positioning plate, the terminal block rotates to change the orientation of the assembly port on the terminal block. There is no need for the operator to first release the clamping and fixing of the terminal block before making the adjustment, which shortens the time required for the terminal block position adjustment and improves the assembly efficiency of the terminal block.

[0015] 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.
[0016] Example 1 Please see Figure 1 - Figure 7 As shown, the purpose of this embodiment is to provide a terminal block assembly support workpiece, including a mounting shell 1. The upper side of the mounting shell 1 is used to place the terminal block, and the lower side of the mounting shell 1 is fixedly connected to a mounting bracket 12. The mounting bracket 12 supports and fixes the mounting shell 1. The mounting shell 1 has an installation groove 11 inside, and a clamping mechanism 2 is provided inside the installation groove 11. The clamping mechanism 2 has two adjusting mechanisms 3 that pass through the installation groove 11 on both sides. When the terminal block is placed on the mounting shell 1, the terminal block is located between the two adjusting mechanisms 3. The clamping mechanism 2 drives the two adjusting mechanisms 3 to move towards the terminal block so as to clamp the terminal block. After the clamping mechanism 2 drives the adjusting mechanisms 3 to clamp the terminal block, the adjusting mechanisms 3 drive the terminal block to rotate, changing the orientation of the terminal block assembly opening. In the initial state, the distance between the two adjustment mechanisms 3 is greater than the length of the terminal block. When the terminal block needs to be assembled, the operator places the terminal block on the mounting shell 1, and the mounting shell 1 supports the terminal block. At this time, the terminal block is located between the two adjustment mechanisms 3. Then, the clamping mechanism 2 drives the two adjustment mechanisms 3 to move towards the terminal block, so that the two moving adjustment mechanisms 3 clamp and fix the terminal block, which makes it easier for the operator to assemble the terminal block and keeps the terminal block stable during the assembly process. When it is necessary to adjust the orientation of the assembly port on the terminal block, the two adjustment mechanisms 3 drive the terminal block to rotate, changing the orientation of the assembly port on the terminal block. This eliminates the need for staff to first release the clamps of the terminal block before making adjustments, shortening the time required for terminal block position adjustment and improving the assembly efficiency of the terminal block.
[0017] refer to Figure 2 - Figure 4 The clamping mechanism 2 includes two movable plates 21 slidably connected inside the mounting groove 11. The ends of the two movable plates 21 that are far apart from each other pass through the mounting groove 11 and extend outward. The end of the movable plate 21 located inside the mounting groove 11 is provided with a placement groove. The placement groove is provided with two electric telescopic rods 22. One end of the electric telescopic rod 22 is fixedly connected to the inside of the mounting groove 11. The piston rod end of the electric telescopic rod 22 is fixedly connected to the inner wall of the placement groove. During the extension and retraction process, the piston rods of the two electric telescopic rods 22 drive the movable plate 21 to move along the axial direction of the mounting groove 11. Under the constraint of the mounting shell 1 and the electric telescopic rods 22, the moving movable plate 21 is kept stable. The movable plate 21 is fixedly connected to a positioning shell 23 at one end outside the mounting groove 11. During the movement of the movable plate 21, the positioning shell 23 is moved. The upper end of the positioning shell 23 is provided with a movable groove 24. Two support rollers are rotatably connected to the opposite side walls of the positioning shell 23 near the bottom. The upper side of the mounting frame 12 is provided with limit grooves near both ends. The bottom of the support rollers rolls in contact with the bottom wall of the limit groove. During the movement of the positioning shell 23, the support rollers are moved. When the moving support rollers rub against the inner wall of the limit groove, the support rollers rotate. The support rollers support the positioning shell 23, which facilitates the movement of the positioning shell 23 and improves the stability of the positioning shell 23 during the movement.
[0018] refer to Figure 3The adjustment mechanism 3 includes a reset assembly, on which a servo motor 32 is mounted. The servo motor 32 can be controlled by an external control system, allowing it to rotate at a corresponding angle as needed. The external control system is a commonly used existing technology in the market, which will not be described in detail in this solution. The control system controls two servo motors 32, causing them to rotate synchronously. The output shaft of the servo motor 32 is connected to a positioning plate 33 via a coupling. The output shaft of the rotating servo motor 32 drives the positioning plate 33 to rotate.
[0019] In the initial state, the bottom of the positioning plate 33 and the terminal block are in contact with the upper side of the mounting housing 1. When the positioning plate 33 rotates, it will drive the terminal block to rotate synchronously, such as... Figure 7 As shown, if the positioning plate 33 is circular, since the cross-section of the terminal block is usually rectangular, when the positioning plate 33 clamps the terminal block, the circular positioning plate 33 cannot completely cover the end face of the terminal block, causing the corner of the terminal block to extend outwards. During the rotation of the positioning plate 33 and the terminal block, the rotation radius of the corner of the terminal block is greater than the radius of the positioning plate 33. Under the restriction of the mounting shell 1, the terminal block experiences greater resistance during rotation. Therefore, when the positioning plate 33 drives the terminal block to rotate, sliding easily occurs between the positioning plate 33 and the terminal block, making it difficult for the rotating positioning plate 33 to accurately drive the terminal block to rotate and adjust its position. At the same time, during the rotation of the positioning plate 33, its lower side will slide into contact with the upper side of the mounting shell 1. During the rotation of the terminal block driven by the positioning plate 33, friction will occur between the side corner of the terminal block and the mounting shell 1. When the terminal block rubs against the mounting shell 1, the side corner of the terminal block will be worn, and the worn terminal block will affect subsequent use.
[0020] Therefore, when designing the shape of the positioning plate 33, the shape of the positioning plate 33 is set to match the shape of the terminal block cross-section, i.e., as shown in the figure. Figure 7 The positioning plate 33 is square in shape, and the upper sides of the mounting shell 1 and the two movable plates 21 are all set as inclined surfaces. During the rotation of the positioning plate 33, the bottom of the positioning plate 33 slides along the inclined surface. Under the constraints of the movable plate 21, the inclined surface, the positioning shell 23 and the extension plate 31, the bottom of the rotating positioning plate 33 slides along the inclined surface and the upper side of the movable plate 21. When the positioning plate 33 rotates, the position of the positioning plate 33 away from the center of rotation will first press the movable plate 21, causing the movable plate 21 to be pressed downward. When the movable plate 21 is pressed downward, the terminal block and the upper surface of the mounting shell 1 separate. At this time, during the rotation of the terminal block driven by the positioning plate 33, the terminal block will not rub against the top of the mounting shell 1, thus ensuring the stable rotation of the terminal block. This allows the positioning plate 33 to accurately change the orientation of the terminal block assembly port during the rotation of the terminal block, so as to facilitate the subsequent assembly of the terminal block.
[0021] The reset assembly includes an extension plate 31 slidably connected inside the moving groove 24. The upper end of the extension plate 31 passes through the moving groove 24 and extends outward. A servo motor 32 is fixedly connected to the side of the extension plate 31 away from the mounting shell 1. Several tension springs 34 are fixedly connected between the bottom of the extension plate 31 and the inner wall of the moving groove 24. When the tension springs 34 are in a stretched state, they contract and drive the extension plate 31 to move along the axial direction of the moving groove 24. After the tension springs 34 contract, the bottom of the positioning plate 33 contacts the upper side of the moving plate 21. The pulling length of the tension springs 34 is greater than the farthest distance from the center of the positioning plate 33 to the corner of the positioning plate 33. When the tension springs 34 are pulled to their longest length, under the restriction of the tension springs 34, the bottom of the extension plate 31 is located inside the positioning shell 23, preventing the extension plate 31 from moving out of the positioning shell 23 and affecting the normal use of the subsequent adjustment mechanism 3.
[0022] When using this device: In the initial state, the distance between the two positioning plates 33 is greater than the length of the terminal block. The operator places the terminal block on the mounting shell 1. The piston rod of the electric telescopic rod 22 retracts, causing the moving plate 21 to move towards the terminal block. The moving plate 21 drives the adjustment mechanism 3 to move, so that the two positioning plates 33 clamp and fix the terminal block, improving the stability of the terminal block during the assembly process. When it is necessary to adjust the orientation of the assembly port on the terminal block, the output shaft of the servo motor 32 rotates, driving the positioning plate 33 to rotate. The rotating positioning plate 33 drives the terminal block to rotate, changing the orientation of the assembly port on the terminal block, making it easier for the staff to assemble the terminal block.
[0023] After the terminal block is assembled, the worker holds the terminal block by hand, and then the electric telescopic rod 22 drives the adjusting mechanism 3 to move, causing the two positioning plates 33 to release their fixation on the terminal block. At this point, the terminal block processing is complete. Then, the positioning plates 33 continue to rotate, rotating to... Figure 7 The first state of the square positioning plate 33, and then the worker takes the new terminal block for processing.
