Description

Technical Field

[0001] This utility model relates to the field of pressure-holding fixture technology, and in particular to a pressure-holding fixture for processing charging copper columns. Background Technology

[0002] In today's global energy transition and green development wave, the new energy industry is booming at an unprecedented speed. Electric vehicles, energy storage systems and various portable electronic devices are generating a surge in demand for efficient and safe charging solutions. As a core component of the new energy charging system, the charging copper column is responsible for the stable and efficient transmission of energy from the external power source to the battery pack. Its processing quality and performance are directly related to the reliability, safety and service life of the entire charging system. Among them, the pressure holding fixture is a common tool in the processing of the charging copper column.

[0003] Existing pressure-holding fixtures for processing charging copper pillars still have some shortcomings in actual use:

[0004] 1. During the pressure holding process, the charging copper column needs to be clamped and fixed. However, the existing clamping devices have relatively fixed dimensions, which makes it difficult to clamp charging copper columns of different diameters.

[0005] 2. Pressure holding fixtures can generate pressure through gas, liquid or mechanical devices to apply uniform force to the workpiece. However, the existing charging copper columns are relatively short and have a fixed height relative to the support platform, making it difficult to use them in conjunction with shorter charging copper columns. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing clamping devices, which have relatively fixed dimensions and are difficult to use for clamping charging copper pillars of different diameters, and whose fixed height makes it difficult to use for charging copper pillars of shorter lengths. Therefore, this invention proposes a pressure-holding fixture for processing charging copper pillars.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A pressure-holding fixture for processing charging copper pillars includes a base and a U-shaped frame. The U-shaped frame is fixedly installed on the top of the base, and a cylinder is fixedly installed on the bottom of the U-shaped frame. A connecting block is fixedly installed on the output shaft of the cylinder. The bottom of the connecting block is provided with multiple conical plates, which can clamp and fix the top of the charging copper pillar. It also includes two support components with the same structure, which are located between a bearing plate and a base plate.

[0009] In one possible design, the tops of the multiple tapered plates are fixedly connected to sliders, and the multiple sliders are slidably connected to the bottom of the connecting block. The bottom outer wall of the connecting block is provided with a threaded section. The outer walls of the multiple tapered plates are provided with the same nut sleeve, and the nut sleeve is threaded onto the outer wall of the connecting block. The outer wall of the tapered plate is provided with a bevel, and the nut sleeve contacts the outer wall of the tapered plate.

[0010] In one possible design, the support assembly includes a bidirectional lead screw rotatably connected to a base plate. Nuts are threaded onto both the positive and negative threaded sections of the bidirectional lead screw. The nuts are slidably disposed within the base plate. A connecting rod is provided above each of the two nuts. A mounting bracket is provided above each of the two connecting rods. The top ends of the two connecting rods are rotatably connected to the mounting brackets. A connecting seat is fixedly connected to the top of each of the two nuts. A connecting shaft is fixedly connected to one side of each of the two connecting seats. The bottom ends of the two connecting rods are rotatably sleeved on the outer wall of the corresponding connecting shaft.

[0011] In one possible design, a rotating shaft is rotatably connected inside the base plate, with one end of the rotating shaft extending to one side of the base plate. A drive motor is fixedly connected to one side of the base plate, and one end of the output shaft of the drive motor is fixedly connected to one end of the rotating shaft. A rotating rod is rotatably connected inside the base plate, and gears are fixedly fitted on the outer wall of both the rotating shaft and the rotating rod, with the two gears meshing.

[0012] In one possible design, both ends of the rotating rod are fixedly fitted with first bevel gears, and the outer walls of the two bidirectional lead screws are fixedly fitted with second bevel gears, with the two first bevel gears meshing with the two second bevel gears respectively.

[0013] In one possible design, the top of the base plate is fixedly connected to four limiting posts, and all four limiting posts slide through the bearing plate.

[0014] In this application, one end of the charging copper column is placed inside a conical plate. When the diameter of the charging copper column is large, the conical plate slides at the bottom of the connecting block via a slider, facilitating the insertion of the charging copper column between multiple conical plates. Rotating the nut sleeve, which is threadedly connected to the connecting block, causes the nut sleeve to rise, engaging with the outer wall of the conical plate to clamp and fix the charging copper column. When the cylinder is energized, its output shaft pushes the connecting block downwards, allowing it to engage with the surface of the bearing plate to achieve a pressure-holding effect. When the length of the charging copper column is short, the drive motor can be started according to the column's length. The output shaft of the drive motor drives the rotating shaft to rotate. One end of the rotating shaft drives two meshing gears to rotate. One of the gears drives the rotating rod to rotate. The rotating rod drives the first bevel gears at both ends to rotate. The two first bevel gears mesh with the two second bevel gears respectively. The second bevel gears drive the double-acting screw to rotate. Through the two opposite threaded sections of the double-acting screw, the screw drives the two nuts to rotate. The two nuts move closer to each other, pushing the two connecting rods to move. The two connecting rods are rotatably connected by the connecting shaft in the mounting bracket, thereby pushing the mounting bracket to move upward. The two mounting brackets push the bearing plate to move upward. The bearing plate is limited to slide up and down by four limiting posts.

[0015] Beneficial effects: In this utility model, the pressure-holding fixture for processing charging copper columns uses multiple sliding conical plates. This fixture can adapt to charging copper columns of different diameters, improving the flexibility and applicability of use. The nut sleeve cooperates with the connecting block to ensure that the conical plates can firmly clamp the charging copper column, preventing loosening or displacement during processing, and improving processing accuracy and stability.

[0016] In this utility model, the pressure-holding fixture for processing charging copper columns is designed with components such as a bidirectional lead screw, nut, connecting rod, and mounting bracket that allow for height adjustment according to the length of the charging copper column. This ensures that the fixture can be used for charging copper columns of different lengths. Through the drive of the drive motor, the automatic adjustment of the support components is realized, further improving processing efficiency and automation.

[0017] In this invention, the pressure-holding fixture for processing charging copper columns has the advantages of flexible clamping design, efficient pressure-holding function, adjustable support components, stable structural design and easy operation and maintenance, which can significantly improve the processing accuracy and efficiency of charging copper columns.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1: Refer to Figure 1 and Figure 4 A pressure-holding fixture includes a base 20 and a U-shaped frame 19. The U-shaped frame 19 is fixedly installed on the top of the base 20, and a cylinder 21 is fixedly installed on the bottom of the U-shaped frame 19. A connecting block 16 is fixedly installed on the output shaft of the cylinder 21. The bottom of the connecting block 16 is provided with multiple conical plates 17, which can clamp and fix the top of the charging copper column. It also includes two support components with the same structure, which are located between the bearing plate 1 and the base plate 2. The U-shaped frame 19 is securely mounted on top of the base 20, ensuring the stability of the overall structure. At the bottom of the U-shaped frame 19, a cylinder 21 is fixedly installed. A connecting block 16 is connected to the output shaft of the cylinder 21. The bottom of the connecting block 16 is designed with multiple conical plates 17. The function of these conical plates 17 is to clamp and fix the top of the charging copper column, ensuring the stability of the charging copper column during processing. In addition, the pressure holding fixture also includes two support components with the same structure. These two support components are located between the bearing plate 1 and the base plate 2, providing additional support and stability for the entire fixture.

[0025] Reference Figure 4Each of the multiple conical plates 17 has a slider 18 fixedly connected to its top, and the sliders 18 are slidably connected to the bottom of the connecting block 16. The bottom outer wall of the connecting block 16 is provided with a threaded section. The outer wall of the multiple conical plates 17 is provided with the same nut sleeve 15, and the nut sleeve 15 is threaded onto the outer wall of the connecting block 16. The outer wall of the conical plate 17 is provided with a bevel, and the nut sleeve 15 contacts the outer wall of the conical plate 17. When the nut sleeve 15 is rotated, because the outer wall of the conical plate 17 is provided with a bevel and contacts the nut sleeve 15, the conical plate 17 will be subjected to an inward squeezing force, thereby achieving a tighter clamping of the charging copper column.

[0026] Reference Figure 3 The support assembly includes a bidirectional lead screw 7 rotatably connected within the base plate 2. Nuts 13 are threaded onto both the positive and negative threaded sections of the bidirectional lead screw 7, and the nuts 13 are slidably disposed within the base plate 2. A connecting rod 4 is positioned above each of the two nuts 13, and a mounting bracket 3 is positioned above each of the two connecting rods 4.

A connecting seat 12 is fixedly connected to the top of each of the two nuts 13, and a connecting shaft 14 is fixedly connected to one side of each connecting seat 12. The bottom ends of the two connecting rods 4 are rotatably sleeved on the outer wall of the corresponding connecting shaft 14. The two opposite threaded sections of the bidirectional lead screw 7 drive the two nuts 13 to rotate, causing them to move closer together and pushing the two connecting rods 4 to move. The two connecting rods 4 are rotatably connected through the connecting shaft within the mounting bracket 3, thereby pushing the mounting bracket 3 upwards. The two mounting brackets 3 then push the bearing plate 1 upwards.

[0027] Reference Figure 2 A rotating shaft 6 is rotatably connected inside the base plate 2, with one end of the rotating shaft 6 extending to one side of the base plate 2. A drive motor is fixedly connected to one side of the base plate 2, and one end of the output shaft of the drive motor is fixedly connected to one end of the rotating shaft 6. A rotating rod 5 is rotatably connected inside the base plate 2, and gears 10 are fixedly fitted on one end of the rotating shaft 6 and the outer wall of the rotating rod 5, with the two gears 10 meshing. When the drive motor starts, it can drive the rotating shaft 6 to rotate. A rotating rod 5 is also rotatably connected inside the base plate 2, and gears 10 are fixedly fitted on one end of the rotating shaft 6 and the outer wall of the rotating rod 5, with the two gears 10 meshing to realize the transmission of power.

[0028] Reference Figure 2 and Figure 3 Both ends of the rotating rod 5 are fixedly fitted with first bevel gears 8, and the outer walls of the two double-acting lead screws 7 are fixedly fitted with second bevel gears 9, with the two first bevel gears 8 meshing with the two second bevel gears 9 respectively. The meshing of the two first bevel gears 8 with the two second bevel gears 9 respectively realizes the power steering and transmission from the rotating rod 5 to the double-acting lead screws 7.
