[0002] In existing technologies, there is often a lack of specialized and highly adaptable clamping fixtures when clamping six-pump ESC actuators. Traditional clamping methods may not be able to accurately and effectively compress the gaskets inside the oil inlet and outlet of the actuator. Due to insufficient gasket compression, oil leakage and other serious performance and quality problems are likely to occur during the subsequent use of the six-pump ESC actuator. Summary of the Invention

[0003] In view of this, the present invention provides a clamping fixture for a six-pump ESC actuator.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A clamping fixture for a six-pump ESC actuator includes a mounting frame, a simulation control box, and a clamping device. The clamping device is disposed on one side of the mounting frame, and the simulation control box is disposed on the top of the mounting frame. A workpiece to be clamped is placed on the simulation control box. The workpiece to be clamped has an oil inlet and an oil outlet, and a sealing gasket is disposed in both the oil inlet and the oil outlet. The clamping device includes a bracket, a longitudinal clamping component disposed on the top of the bracket, and a horizontal clamping component disposed through the bracket. The longitudinal clamping component and the horizontal clamping component move horizontally from one side above the workpiece to be clamped toward the oil inlet and the oil outlet on the workpiece to be clamped and clamp the sealing gaskets in the oil inlet and the oil outlet, respectively.

[0005] Preferably, the longitudinal clamping assembly includes an eccentric wheel mounting block fixed to the upper part of the bracket and a guide block fixed to the middle part of the bracket. The eccentric wheel mounting block is provided with a rotatable eccentric wheel, and the eccentric wheel and the eccentric wheel mounting block are arranged in an eccentric structure. The guide block is provided with a longitudinal clamping unit, one end of which is connected to the eccentric wheel. During the rotation of the eccentric wheel, the longitudinal clamping unit is driven to move towards the oil inlet.

[0006] Preferably, an elastic steel column screw is provided inside the eccentric wheel, and the elastic steel column screw limits the rotation of the eccentric wheel.

[0007] Preferably, the longitudinal clamping unit includes a guide shaft, a pressure rod, a return spring, a connecting block, and an oil inlet pressure block. The guide shaft and the pressure rod both pass through the guide block. The connecting block is located at the top of the oil inlet pressure block and connected to it. The top of the pressure rod is connected to an eccentric wheel, and the bottom of the pressure rod is connected to the connecting block. During the rotation of the eccentric wheel, the pressure rod is driven to press down. As the pressure rod presses down, it drives the oil inlet pressure block to move towards the oil inlet through the connecting block, applying pressure to the sealing gasket inside the oil inlet.

[0008] Preferably, the pressure rod has a transmission end, which is located at the top of the pressure rod and connected to the eccentric wheel. The return spring is sleeved on the part of the pressure rod located between the guide block and the transmission end, and the two ends of the return spring abut against the bottom of the transmission end and the top of the guide block, respectively.

[0012] The beneficial effects of this utility model are as follows: the bracket, as the basic support structure of the entire clamping device, ensures the stable installation of the longitudinal and horizontal clamping components. The longitudinal clamping component moves from above the workpiece towards the oil inlet and outlet, effectively applying pressure to the vertical sealing gasket to ensure a sealing effect. The horizontal clamping component moves from one side of the workpiece towards the oil inlet and outlet, further clamping the sealing gasket horizontally. This combination of dual clamping methods greatly improves the stability and sealing of the clamping process, avoiding potential oil leakage due to poor sealing and ensuring the quality and performance of the six-pump ESC actuator during clamping.

Detailed Implementation

[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] The present invention will now be further described with reference to the accompanying drawings.

[0017] This utility model provides the following technical solution: As attached Figure 1-6As shown, this utility model discloses a clamping fixture for a six-pump ESC actuator, including a mounting frame 1, a simulation control box 2, and a clamping device 3. The clamping device 3 is disposed on one side of the mounting frame 1, and the simulation control box 2 is disposed on the top of the mounting frame 1. A workpiece 4 to be clamped is placed on the simulation control box 2. The workpiece 4 has an oil inlet (not shown) and an oil outlet (not shown). Both the oil inlet and the oil outlet are provided with sealing gaskets. The clamping device 3 includes a bracket 7, a longitudinal clamping component 8 disposed on the top of the bracket 7, and a horizontal clamping component 9 that penetrates the bracket 7. The longitudinal clamping component 8 and the horizontal clamping component 9 move horizontally from one side above the workpiece 4 toward the oil inlet and the oil outlet, respectively, and clamp the sealing gaskets in the oil inlet and the oil outlet. Specifically, in this design, the bracket 7 serves as the basic support structure for the entire clamping device 3, ensuring the stable installation of the longitudinal clamping component 8 and the horizontal clamping component 9. The longitudinal clamping assembly 8 moves from above the workpiece 4 towards the oil inlet and outlet, effectively applying pressure to the vertical sealing gasket to ensure a tight seal. The horizontal clamping assembly 9 moves from one side of the workpiece 4 towards the oil inlet and outlet, further clamping the sealing gasket horizontally. This dual clamping method significantly improves clamping stability and sealing, preventing oil leakage and other problems caused by poor sealing, thus ensuring the quality and performance of the six-pump ESC actuator during clamping. The analog control box 22 is used to control the operation of the product's solenoid valves and acquire sensor data.

[0018] Furthermore, the longitudinal clamping assembly 8 includes an eccentric wheel mounting block 10 fixed to the upper part of the bracket 7 and a guide block 11 fixed to the middle part of the bracket 7. A rotatable eccentric wheel 12 is mounted on the eccentric wheel mounting block 10, and the eccentric wheel 12 and the eccentric wheel mounting block 10 are arranged in an eccentric structure. A longitudinal clamping unit 13 is mounted on the guide block 11, and one end of the longitudinal clamping unit 13 is connected to the eccentric wheel 12. During the rotation of the eccentric wheel 12, the longitudinal clamping unit 13 moves towards the oil inlet. Specifically, in this embodiment, the eccentric wheel mounting block 10 provides a stable mounting base for the eccentric wheel 12, and the eccentric structure between it and the eccentric wheel 12 is key to the clamping function of the longitudinal clamping assembly 8. When the eccentric wheel 12 rotates, due to the eccentric structure, the longitudinal clamping unit 13 connected to it moves towards the oil inlet along the direction defined by the guide block 11. The guide block 11 guides and restricts the movement trajectory of the longitudinal clamping unit 13, ensuring that the longitudinal clamping unit 13 can move accurately in the target direction, thereby applying stable pressure to the sealing gasket in the oil inlet and ensuring the sealing effect at the oil inlet. This design cleverly utilizes the rotational characteristics of the eccentric wheel 12 to convert rotational motion into longitudinal linear motion, achieving effective clamping of the sealing gasket at the oil inlet of the workpiece 4 to be clamped.

[0019] Furthermore, the longitudinal pressing unit 13 includes a guide shaft 14, a pressure rod 15, a return spring (not shown), a connecting block 17, and an oil inlet pressure block 18. The guide shaft 14 and pressure rod 15 both pass through the guide block 11. The connecting block 17 is located at the top of the oil inlet pressure block 18 and connected to it. The top of the pressure rod 15 is connected to the eccentric wheel 12, and the bottom of the pressure rod 15 is connected to the connecting block 17. During rotation, the eccentric wheel 12 drives the pressure rod 15 downwards. As the pressure rod 15 presses down, it drives the oil inlet pressure block 18 to move towards the oil inlet through the connecting block 17, applying pressure to the sealing gasket inside the oil inlet. Specifically, in this embodiment, the guide shaft 14 plays a stabilizing and guiding role, ensuring that the pressure rod 15 and the oil inlet pressure block 18 do not deviate during movement and maintain a vertically downward trajectory. The pressure rod 15, as a key component for transmitting the rotational power of the eccentric wheel 12, connects to the eccentric wheel 12 at its top and to the connecting block 17 at its bottom. When the eccentric wheel 12 rotates, the pressure rod 15 moves up and down accordingly. A return spring is located on the portion of the pressure rod 15 between the guide block 11 and the transmission end 19. Its function is to provide an upward rebound force after the pressure rod 15 is pressed down, allowing it to quickly return to its original position after the pressing action, preparing for the next pressing action. The connecting block 17, as the connector between the pressure rod 15 and the oil inlet pressure block 18, plays a role in transmitting and distributing pressure, ensuring that the downward pressure of the pressure rod 15 is evenly applied to the oil inlet pressure block 18. The oil inlet pressure block 18 is the component that directly applies pressure to the sealing gasket inside the oil inlet. Its shape and size are designed according to the actual situation of the oil inlet to ensure a tight fit against the sealing gasket and achieve effective sealing. The design of this longitudinal clamping unit 13, through the coordinated work of various components, achieves stable and effective clamping of the sealing gasket inside the oil inlet, thereby improving the reliability and sealing performance of the clamping.

[0020] Furthermore, the pressure rod 15 has a transmission end 19, which is located at the top of the pressure rod 15 and connects to the eccentric wheel 12. A return spring is sleeved on the portion of the pressure rod 15 located between the guide block 11 and the transmission end 19, with both ends of the return spring abutting against the bottom of the transmission end 19 and the top of the guide block 11, respectively. Specifically, in this embodiment, the transmission end 19 enables the pressure rod 15 to achieve good power transmission with the eccentric wheel 12. When the eccentric wheel 12 rotates, the transmission end 19 can accurately receive the force transmitted by the eccentric wheel 12, thereby driving the pressure rod 15 to move up and down. The return spring is sleeved on the portion of the pressure rod 15 located between the guide block 11 and the transmission end 19. This design allows the return spring to be compressed when the pressure rod 15 is pressed down, generating an upward rebound force. When the eccentric wheel 12 stops applying downward force to the pressure rod 15, the rebound force of the return spring will quickly push the pressure rod 15 upward back to its initial state, preparing for the next pressing action. This design ensures that the longitudinal clamping assembly 8 can perform continuous and stable clamping and return operations, improving the working efficiency and reliability of the clamping fixture. Meanwhile, the two ends of the return spring abut against the bottom of the transmission end 19 and the top of the guide block 11, respectively. This installation method ensures that the return spring maintains a stable movement trajectory during compression and rebound, preventing deviation or jamming, further guaranteeing the normal operation of the longitudinal clamping assembly 8.

[0021] Furthermore, an eccentric wheel shaft 20 is disposed through the eccentric wheel 12, and one end of the eccentric wheel shaft 20 extends into the eccentric wheel mounting block 10 and is rotatably connected to the eccentric wheel mounting block 10. Specifically, in this embodiment, the eccentric wheel shaft 20 passes through the eccentric wheel 12, and one end extends into the eccentric wheel mounting block 10 and is rotatably connected to the eccentric wheel mounting block 10. This connection method ensures that the eccentric wheel 12 can rotate freely around the shaft and also ensures the stability of the eccentric wheel 12 during rotation. The eccentric wheel mounting block 10 provides a precise mounting position for the eccentric wheel shaft 20, enabling the eccentric wheel 12 to maintain an accurate eccentric trajectory during rotation, thereby driving the longitudinal pressing unit 13 to move in a predetermined direction and distance.

[0022] Furthermore, the horizontal clamping assembly 9 includes a screw 21, a screw mounting block 22, and an oil outlet pressure block 23. The screw mounting block 22 is disposed on the side of the bracket 7 away from the workpiece 4 to be clamped. A movable groove 24 is formed on the screw mounting block 22. Both the oil outlet pressure block 23 and the screw pressure block 27 are disposed within the movable groove 24. An opening is formed on the bracket 7 connecting the movable groove 24 to the outside of the movable groove 24. One end of the oil outlet pressure block 23 passes through the bracket 7 through the opening, and one end of the screw 21 extends into the movable groove 24 and abuts against the oil outlet pressure block 23. Specifically, in this embodiment, the movable groove 24 on the screw mounting block 22 provides space for the oil outlet pressure block 23 and the screw pressure block 27 to move. One end of the oil outlet pressure block 23 passes through the bracket 7 through the opening, allowing the oil outlet pressure block 23 to contact the sealing gasket inside the oil outlet of the workpiece 4 to be clamped. One end of the screw 21 extends into the movable groove 24 and abuts against the oil outlet pressure block 23. When the screw 21 is rotated, it moves along the direction of the movable groove 24, thereby pushing the oil outlet pressure block 23 towards the oil outlet, applying pressure to the sealing gasket inside the oil outlet, and achieving horizontal clamping. This design converts the rotational motion of the screw 21 into the linear motion of the oil outlet pressure block 23, simply and effectively achieving the clamping of the sealing gasket at the oil outlet of the workpiece 4 to be clamped. In conjunction with the longitudinal clamping assembly 8, it further improves the clamping stability and sealing performance.

[0023] Furthermore, a T-shaped block 25 is provided on the side of the oil outlet pressure block 23 near the screw 21. The T-shaped block 25 is fixed to the oil outlet pressure block 23 by screws. A limiting groove 26 is formed on the T-shaped block 25. One end of the screw 21 extends into the limiting groove 26, and a screw pressure block 27 is provided on the end of the screw 21 that extends into the limiting groove 26. The screw pressure block 27 is connected to the screw 21, and the screw pressure block 27 is in a limiting contact with the groove wall of the limiting groove 26. Specifically, in this embodiment, the T-shaped block 25 enhances the connection stability between the oil outlet pressure block 23 and the screw 21. By fixing it to the oil outlet pressure block 23 with screws, the T-shaped block 25 can move together with the oil outlet pressure block 23. The limiting groove 26 on the T-block 25 provides precise installation and movement space for the screw 21. One end of the screw 21 extends into the limiting groove 26 and is engaged with the groove wall of the limiting groove 26 via the screw pressure block 27. This design ensures that the screw 21 can stably push the oil outlet pressure block 23 to move during rotation without deviation or detachment. At the same time, the connection between the screw pressure block 27 and the screw 21 also ensures effective force transmission, allowing the rotational motion of the screw 21 to be smoothly converted into the linear motion of the oil outlet pressure block 23, thereby achieving stable compression of the sealing gasket inside the oil outlet.

[0024] Furthermore, an elastic steel ball screw 28 is provided inside the eccentric wheel to limit the rotation of the eccentric wheel. Specifically, in this embodiment, an elastic steel ball screw 28 is provided to automatically lock the eccentric wheel when it is in the pressing position, preventing the cam from moving in the opposite direction during operation.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
