[0024] The utility model is further described in conjunction with the following embodiments.

[0025] The specific implementation of the four-axis fixture for inserting the valve cover of the utility model is as follows: Figure 2 and Figure 3 As shown, it includes a base plate 2 and a plurality of pressing oil cylinders 3. There are five pressing oil cylinders 3 in total, and the five pressing oil cylinders 3 are arranged on the base plate 2 at intervals in the transverse direction.

[0026] In this embodiment, five clamping oil cylinders 3 are fixedly installed at intervals on the top surface of the bottom plate 2 in a horizontal straight line arrangement, and the piston rod of each clamping oil cylinder 3 is fixedly connected to a clamping block 31. A rectangular station is formed between two adjacent clamping oil cylinders 3, and a plurality of spacers 21 are arranged at intervals and fixed on the top surface of the bottom plate 2. As a preferred solution, the number of the spacers 21 is set to four, and the four spacers 21 are evenly spaced on the bottom plate 2 in a cross shape.

[0027] In order to limit the free end of the workpiece in the front-to-back direction, the rectangular station is also provided with a positioning block located at the front side of the rectangular station and fixedly mounted on the top surface of the bottom plate 2, and a clamping arm 42 located at the rear side of the rectangular station and capable of reciprocating longitudinal sliding. Specifically, the rear side of the bottom plate 2 is provided with a plurality of slide grooves 22 arranged at intervals in the transverse direction, each slide groove 22 corresponds to a rectangular station, the clamping arm 42 is placed in the vertical direction and inserted into the slide groove 22, the bottom plate 2 is also provided with a plurality of clamping cylinders 41, the plurality of clamping cylinders 41 are arranged at intervals in the transverse direction and fixedly mounted on the bottom surface of the bottom plate 2, the piston rod of the clamping cylinder 41 is fixedly connected to the clamping arm 42, so that the clamping arm 42 can slide along the slide groove 22, and the clamping arm 42 can clamp the workpiece in the longitudinal direction in cooperation with the positioning block, thereby limiting the degree of freedom of the workpiece in the front-to-back direction.

[0028] In this embodiment, since the rotary head rotates in only one direction during milling, an anti-rotation block fixed on the bottom plate 2 is provided at the lower left corner of each rectangular work station to prevent the workpiece from rotating during the machining process.

[0029] Please see Figure 3A mounting hole is provided in the middle of the clamping block 31. In the assembled state, the piston rod of the clamping cylinder 3 is inserted and fixed in the mounting hole, and the clamping block 31 is arranged in a T shape. As an improvement, both ends of the clamping block 31 gradually narrow outward. Specifically, both ends of the clamping block 31 are arranged in a trapezoidal shape. This structure does not affect the clamping block 31 from providing sufficient clamping force, while ensuring that the connection strength between the clamping block 31 and the clamping cylinder 3 is sufficiently strong, and reduces the contact area between the clamping piece and the workpiece as much as possible, reducing the occurrence of workpiece damage. This can also reduce the preparation materials used for the clamping piece, reducing production costs and weight.

[0030] As an improvement, the rotating assembly includes a rotating motor 51, a rotating disk 52 and an L-shaped connecting plate 53, the output shaft of the rotating motor 51 is fixedly connected to the rotating disk 52, one side of the L-shaped connecting plate 53 is fixedly mounted on the rotating disk 52, and the other side of the connecting plate is fixedly connected to the bottom plate 2. When the workpiece needs to change the processing plane, the rotating motor 51 drives the rotating disk 52 to rotate, and the rotation of the rotating disk 52 drives the L-shaped connecting plate 53 and the bottom plate 2 to rotate, thereby changing the orientation of the workpiece.

[0031] A four-axis clamp for a cartridge valve cover in this embodiment has a simple and compact overall structure, a reasonable design layout, and a low manufacturing cost. It can quickly and accurately position each workpiece, and the cartridge valve cover can be quickly fastened and disassembled through a hydraulic system, with high work efficiency. Multiple workpieces can be clamped at the same time, and the time spent on disassembly and assembly is short, which solves the problem of low clamping efficiency in the past and improves processing efficiency. It reduces the number of manual labor and the labor intensity of workers, improves product processing quality, and reduces the defective rate of products, which improves the efficiency of production enterprises and plays a major role in reducing and saving the production costs of enterprises. In addition, by setting a rotating component, the rotating component drives the base plate 2 to rotate, and the orientation of the workpiece can be changed, so that the processing plane of the workpiece can be changed without disassembling the workpiece, reducing the number of disassembly and assembly times and improving work efficiency.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
