[0017] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.

[0018] Seen in Figure 1This embodiment provides a double-sided milling fixture for a cover plate 101, which includes a base plate 100. A front support block 110 and a back support block 120 are sequentially arranged on one side of the base plate 100. The front support block 110 is used to abut against the front of the cover plate 101, and the back support block 120 is used to abut against the back of the cover plate 101. A back pressure plate 130 is provided on the side of the front support block 110 away from the base plate 100, and the back pressure plate 130 is used to abut against the back of the cover plate 101. A front support block 120 is provided on the side of the back support block 120 away from the base plate 101. A front pressure plate 140 is used to abut against the cover plate 101. A first driving part 150 is provided on the side of the bottom plate 100 away from the front support block 110. The first driving part 150 is used to drive the front pressure plate 140 and the back pressure plate 130 to abut against and separate from the cover plate 101. A second driving part 160 is also provided on the top of the bottom plate 100. A positioning plate 161 is provided at the second driving part 160. The second driving part 161 is used to drive the positioning plate 161 to abut against and separate from the front support block 110 and the back support block 120.

[0019] According to the solution provided in this embodiment, a cover plate 101 is provided at both the front support block 110 and the back support block 120. The back pressure plate 130 cooperates with the front support block 110, and the front pressure plate 140 cooperates with the back support block 120, thereby fixing the two cover plates 101. The first driving unit 150 can drive the front pressure plate 140 and the back pressure plate 130 to clamp the two cover plates 101. The second driving unit 160 can drive the positioning plate 161 to abut against the front support block 110 and the back support block 120, thereby improving the stability of the front support block 110 and the back support block 120 during processing.

[0020] Specifically, since face milling is a subtractive machining process, the milling cutter needs to contact the workpiece, which makes the workpiece prone to displacement. The positioning plate 161 abuts against the front support block 110 and the back support block 120, reducing the vibration of the front support block 110 and the back support block 120 during machining, thereby improving the stability of the front pressure plate 140 and the back pressure plate 130 clamping the cover plate 101, and thus improving the machining accuracy of face milling.

[0021] Furthermore, a first mating groove 211 is formed on the side of the front support block 110 away from the base plate 100, and the first mating groove 211 is used to conformally mate with the front of the cover plate 101; a second mating groove 231 is formed on the side of the back pressure plate 130 near the front support block 110, and the second mating groove 231 is used to conformally mate with the back of the cover plate 101; a third mating groove 221 is formed on the side of the back support block 120 away from the base plate 100, and the third mating groove 221 is used to conformally mate with the back of the cover plate 101; a fourth mating groove 241 is formed on the side of the front pressure plate 140 near the back support block 120, and the fourth mating groove 241 is used to conformally mate with the front of the cover plate 101.

[0022] Seen in Figure 1-4 The first drive unit 150 includes a clamping cylinder 251, which has a retractable first piston rod 3511. A transition shaft 252 is connected to the end of the first piston rod 3511. The end of the transition shaft 252 away from the piston rod abuts against the front pressure plate 140 and the back pressure plate 130. The transition shaft 252 forms a first mating hole 3512 through the axis. A semi-circular mating groove is formed at the mating end of the front pressure plate 140 and the back pressure plate 130. A screw 253 is provided at the mating groove. A second mating hole 3513 is formed at the first piston rod 3511. The second mating hole 3513 is used to thread with the screw 253.

[0023] Specifically, the front pressure plate 140, the back pressure plate 130 and the first piston rod 3511 can be connected by screws 253 and transition shaft 252, so that the first piston rod 3511 can simultaneously drive the front pressure plate 140 and the back pressure plate 130 to lift and lower to clamp the cover plate 101.

[0024] Seen in Figure 1-2 The second drive unit 160 includes a positioning cylinder 262, which has a retractable second piston rod 263, the end of which is fixedly engaged with a positioning block.

[0025] Furthermore, a support plate 264 is fixedly provided at the bottom of the positioning cylinder 262, and the side of the support plate 264 away from the positioning cylinder 262 is fixedly engaged with the base plate 100. Therefore, the positioning cylinder 262 can be installed at the base plate 100.

[0026] Seen in Figure 1-2 The base plate 100 has two feet 270 spaced apart at one end near the first drive part 150, and the two feet 270 are located on both sides of the first drive part 150. By providing the feet 270, the installation of the clamping cylinder 251 can be facilitated.

[0027] Working principle:

[0028] Clamping cylinder 251 drives the front pressure plate 140 and the back pressure plate 130 away from the base plate 100, placing the two cover plates 101 at the front support block 110 and the back support block 120, with the front of the cover plate 101 abutting against the front support block 110 and the back of the cover plate 101 abutting against the back support block 120. Then, clamping cylinder 251 drives the front pressure plate 140 and the back pressure plate 130 closer to the base plate 100, abutting against the two cover plates 101. Then, positioning cylinder 262 drives the positioning block closer to and abutting against the front support block 110 and the back support block 120, completing the clamping of the two cover plates 101. After that, milling can be performed. After the milling is completed, positioning cylinder 262 drives the positioning block away from the front support block 110 and the back support block 120, and clamping cylinder 251 drives the front pressure plate 140 and the back pressure plate 130 away from the base plate 100, thereby facilitating the removal of the two machined cover plates 101.

[0029] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.

[0030] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the embodiments shown are only part of the embodiments of the present invention. The actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
