[0002] The electric actuator housing has a complex shape and many processing steps. It is inconvenient to clamp during processing, making it difficult to position and clamp, which affects the processing accuracy. Therefore, it needs to be improved. Summary of the Invention

[0003] This utility model provides a hydraulic clamp for electric actuator housings to solve the clamping and fixing problem during the machining of electric actuator housings.

[0004] This utility model is achieved through the following technical solution: A hydraulic clamp for an electric actuator housing, characterized in that: it includes a four-axis base plate, a four-axis machine base installed at the front of the base plate, and a four-axis tailstock installed at the rear of the base plate. A hydraulic clamp base plate is also installed on the four-axis base plate, and a plurality of clamping hydraulic cylinders, adjusting hydraulic cylinders, and fixing hydraulic cylinders are installed on the hydraulic clamp base plate. The hydraulic clamp is controlled by three oil circuits. Oil circuit one controls each adjusting hydraulic cylinder to align the bottom plane of the actuator housing, i.e., the positioning function; oil circuit two controls each fixing hydraulic cylinder to adjust the direction of the actuator housing in a small range from the front and rear sides and the left and right sides; oil circuit three controls each clamping hydraulic cylinder to clamp the actuator housing from above.

[0005] Further preferably, 3-10 adjusting hydraulic cylinders are used, which are vertically fixed to the base plate of the hydraulic fixture with bolts and located on the four sides of the bottom of the actuator housing; 5-10 fixing hydraulic cylinders are used, which are fixed to the base plate of the hydraulic fixture with bases and bolts and arranged on the front, back, left and right sides of the actuator housing; 10-20 clamping hydraulic cylinders are used, which are vertically fixed to the base plate of the hydraulic fixture with support seats and bolts and arranged around the actuator housing.

[0006] In a further preferred embodiment, each hydraulic cylinder on the hydraulic fixture base plate is used to mount and fix two actuator housings, and to process the two actuator housings simultaneously, wherein the parts processed on the two actuator housings are the same or different.

[0007] A further preferred embodiment is a hydraulic cylinder with a clamping bending arm mounted on its upper end.

[0008] The beneficial effects of this utility model are that by combining multiple clamping hydraulic cylinders, adjusting hydraulic cylinders, and fixing hydraulic cylinders, the positioning, adjusting, and clamping functions of the actuator housing are realized respectively, thereby achieving rapid clamping, improving clamping efficiency, reducing the difficulty of clamping, ensuring processing accuracy, reducing scrap rate, and saving costs.

[0010] . Detailed Implementation

[0011] The attached figure shows a specific embodiment of this utility model.

[0012] The electric actuator housing hydraulic clamp of this utility model includes a four-axis base plate 2, a four-axis machine base 1 installed at the front of it, and a four-axis tailstock 3 installed at the rear of it. A hydraulic clamp base plate 26 is also installed on the four-axis base plate. Several clamping hydraulic cylinders, adjusting hydraulic cylinders and fixing hydraulic cylinders are installed on the hydraulic clamp base plate. The hydraulic clamp is controlled by three oil circuits. Oil circuit one controls each adjusting hydraulic cylinder to align the bottom plane of the actuator housing, i.e., the positioning function; oil circuit two controls each fixing hydraulic cylinder to adjust the direction of the actuator housing in a small range from the front and rear sides and the left and right sides; oil circuit three controls each clamping hydraulic cylinder to clamp the actuator housing from above.

[0013] Three to ten adjusting hydraulic cylinders are vertically fixed to the base plate of the hydraulic fixture with bolts, located on the four sides of the bottom of the actuator housing; five to ten fixing hydraulic cylinders are fixed to the base plate of the hydraulic fixture with bases and bolts, arranged on the front, back, left and right sides of the actuator housing; and ten to twenty clamping hydraulic cylinders are vertically fixed to the base plate of the hydraulic fixture with support seats and bolts, arranged around the actuator housing.

[0014] The hydraulic cylinders on the hydraulic fixture base plate 26 are used to install and fix the two actuator housings, and to process the two actuator housings simultaneously. The parts processed on the two actuator housings may be the same or different.

[0015] The hydraulic cylinder is clamped, and the upper end is equipped with a clamping curved arm 27.

[0016] A 4-axis CNC machine tool is used, and the fixture is mounted on this machine tool for machining the workpiece. The hydraulic fixture is controlled by three separate hydraulic circuits. Hydraulic circuit one controls the adjusting hydraulic cylinders 21-25 to align the bottom plane of the two actuator housings; hydraulic circuit two controls the fixing hydraulic cylinders 8, 11, 13, 15, and 19 to adjust the orientation of the actuator housings in a small range from the front, rear, left, and right sides; hydraulic circuit three controls the clamping hydraulic cylinders 6, 7, 9, 10, 12, 14, 16, 17, 18, and 20 to clamp the actuator housings from above.

[0017] Actuator housing one is placed on the left side of the fixture. The hydraulic cylinder is adjusted for bottom positioning. The fixed hydraulic cylinder finely adjusts the workpiece orientation from four sides (front, back, left, and right) and clamps the workpiece. Then, the clamping hydraulic cylinder clamps the workpiece from above. Actuator housing two is placed on the right side of the fixture. The hydraulic cylinder is adjusted for bottom positioning. The fixed hydraulic cylinder finely adjusts the workpiece orientation from four sides (front, back, left, and right) and clamps the workpiece. Then, the clamping hydraulic cylinder clamps the workpiece from above.
