Detailed Implementation

[0017] The specific embodiments of this utility model will be described below with reference to the accompanying drawings.

[0018] Please see Figures 1 to 8 This utility model discloses a high-pressure oil cup clamp for pressing an oil cup 4, thereby enabling efficient and precise machining of the oil cup 4. The oil cup 4 is a cylinder with an opening on one side. There is an opening on the sealed side. Machining the oil cup 4 involves further processing around the opening to form the shape required for the final product. This machining must be completed after the oil cup 4 is fixed.

[0019] A preferred embodiment of it includes a base plate 1, a pressing unit 2, and a positioning unit 3.

[0020] The base plate 1 is a single piece of Cr12 thick plate, with mounting holes and oil passage holes for fixing other parts on it. Four adjustable feet 11 are also provided under the base plate 1. The clamping unit 2 and positioning unit 3 cooperate to clamp and fix the oil cups 4 for easy processing. Four clamping units 2 are simultaneously installed and fixed on the base plate 1. Each clamping unit 2 corresponds to two positioning units 3. The positioning units 3 correspond one-to-one with the oil cups 4, defining the position and angle of the oil cups 4. In this embodiment, eight oil cups 4 can be clamped simultaneously on one base plate 1 using four clamping units 2, and these eight oil cups 4 can be processed at the same time.

[0021] The clamping unit 2, used to clamp and fix the oil cup 4, consists of a hydraulic cylinder 21, a pressure plate 22, and a pressure block 23. The pressure plate 22 and pressure block 23 combine to form a fastening module. The hydraulic cylinder 21 is fixed to the base plate 1. The pressure plate 22 is detachably fixed to the movable end of the hydraulic cylinder 21 by clamping bolts 24. One pressure plate 22 corresponds to two pressure blocks 23. Each pressure block 23 is installed opposite to the positioning unit 3. Driven by the hydraulic cylinder 21, the pressure plate 22 moves the pressure block 23 closer to the positioning unit 3 until the pressure block 23 contacts the oil cup 4, which is pressed and fixed on the positioning unit 3, thus completing the fixing of the oil cup 4. A hydraulic cylinder sealing plate 25 is also provided at the bottom of the hydraulic cylinder 21. The hydraulic cylinder sealing plate 25 is fixed to the base plate 1 and is used to cover the maintenance hole of the hydraulic cylinder 21. When maintenance of the hydraulic cylinder 21 is required, the hydraulic cylinder sealing plate 25 can be removed.

[0022] The positioning unit 3 consists of two parts: a first positioning module 31 and a second positioning module. The first positioning module 31 is cylindrical and used for circumferential positioning. The outer diameter of the first positioning module 31 matches the inner diameter of the oil cup 4, allowing the oil cup 4 to fit onto the first positioning module 31, thus limiting the position of the oil cup 4 on the base plate 1. The second positioning module consists of a main positioning pin 32 and a vertical positioning pin 33, both mounted on the first positioning module 31. The main positioning pin 32 and the vertical positioning pin 33 match the shape of the bottom surface of the oil cup 4. The main positioning pin 32 determines the angle of the oil cup 4, while the vertical positioning pin 33 determines the vertical height of the oil cup 4.

[0023] Specifically, the main positioning pin 32 is an elastic positioning pin, further composed of a positioning post 321 and a spring 322. The positioning post 321 and the spring 322 pass through the positioning hole on the first positioning module 31 and are fitted into the positioning hole. In the positioning hole, the spring 322 is located below the positioning post 321, with its lower end abutting against the base plate and its upper end abutting against the lower part of the positioning post 321, thereby lifting the positioning post 321 from bottom to top. The position of the positioning hole on the first positioning module 31 corresponds to the opening on the bottom surface of the oil cup 4. The outer diameter of the positioning post 321 is slightly larger than the opening on the bottom surface of the oil cup 4. Thus, when the oil cup 4 is placed on the positioning unit 3, it can only rotate under the restriction of the first positioning module 31. When it rotates to the position where the opening on the oil cup 4 aligns with the positioning post 321, the positioning post 321, pushed by the spring 322, engages with the opening but continues to maintain pressure on the oil cup 4, thereby fixing the current angle of the oil cup 4 and completing the angle positioning.

[0024] There are three vertical positioning pins 33, all of which are thin cylindrical protrusions. They are located on the cylindrical end face of the first positioning module 31. The height of the vertical positioning pins 33 and the cylindrical height of the first positioning module 31 are added together and are greater than the height of the oil cup 4. This ensures that the oil cup 4 is in a known position in the vertical direction after it is clamped.

[0025] In production, the oil cup 4 is first pre-positioned on the tooling using the positioning unit 3. Specifically, the oil cup 4 is fitted onto the large outer circumference of the first positioning module 31, and then the oil cup 4 is rotated until the small hole on the oil cup 4 aligns with the main positioning pin 32. The diameter of the small hole is slightly smaller than that of the positioning pin 321, so after the spring 322 pushes the positioning pin 321 against the small hole to complete the pre-positioning, the positioning pin 321 continues to provide continuous pressure on the oil cup 4. Then, the clamping unit 2 activates, and the clamping block 23 presses the oil cup 4 downwards, with the height determined by the vertical positioning pin 33. The shape of the clamping block 23 avoids the small hole on the oil cup 4, thus facilitating processing of the small hole area of ​​the oil cup while clamping. After processing, the clamping unit 2 releases the oil cup 4, and under the action of the spring 322, the positioning pin 321 springs up the oil cup 4, facilitating unloading.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made within the scope of the claims of this utility model should be considered within the technical scope of this utility model.
