[0002] Cadmium antimonide material is a new type of semiconductor material, which has the characteristics of appropriate optical band gap, low material cost, large absorption coefficient, stable chemical properties, and low crystal growth temperature. It is a promising thin-film photovoltaic material for the light absorber of solar cells and is very suitable for making new thin-film solar cells. Cadmium antimonide thin films are prepared by radio frequency magnetron sputtering method in a vacuum coating equipment, and cadmium antimonide thin films are prepared by changing conditions such as different sputtering powers, substrate temperatures, and chamber pressures.

[0003] The vacuum coating equipment chamber has a large-scale ultra-thin variable-diameter conical shell. During the processing and manufacturing process, the large-scale ultra-thin variable-diameter conical shell has extremely high processing accuracy requirements for each component structural part, and any appearance damage to the shell is not allowed during the production process. The conical shell undergoes thousands of processes from the blank to the product, and a large number of transfers, clamps, and unclamps are involved in each process, which is extremely easy to damage the conical shell. This makes the protection of the product during the process particularly important.

[0004] This type of shell is a large-scale ultra-thin variable-diameter conical structure. To ensure the machining accuracy, safety, and reliability of the inner surface and end face of the shell, a numerically controlled horizontal lathe is selected and the machining is completed with a high-precision tooling. It is necessary to first vertically install the conical shell and the turning fixture together, and then hoist the conical shell and the turning fixture as a whole onto the lathe. After the machining is completed, the conical shell and the turning fixture are removed from the lathe as a whole. The existing machining fixture process has low efficiency and poor quality, cannot fundamentally meet the requirements of contact area and roughness, and has poor interchangeability.

Specifically, each retaining block 30 is provided with three connection holes 31, and the sleeve 10 is correspondingly provided with threaded connection holes 14, and the retaining blocks 30 are detachably installed on the sleeve 10 by screws.

[0022] Inside the sleeve 10 between the retaining ring 20 and the retaining block 30, there is also a detachably connected first support ring 60. The first support ring 60 is centered inside the sleeve 10. The core of the first support ring 60 has an inner conical surface that mates with the outer conical surface of the workpiece 40. The outer periphery of the first support ring 60 is a cylindrical surface that matches the inner side surface of the sleeve 10. On the outer cylindrical surface of the first support ring 60, there is a set of first threaded holes 61 arranged in a circular array. On the sleeve 10, there is a set of first waist-shaped holes 12 that penetrate the sleeve. The first threaded holes 61 and the first waist-shaped holes 12 are in one-to-one correspondence and cooperation. The first waist-shaped holes 12 are arranged along the axial direction of the sleeve 10. In this way, the axial position of the first support ring 60 can be adjusted along the first waist-shaped holes 12 to make the inner conical surface of the first support ring 60 match the outer conical surface of the workpiece 40. Then, a screw penetrates the sleeve 10 and is connected to the first support ring 60, and the position of the first support ring 60 is fixed by tightening, and then a stable support is formed for the workpiece 40.

[0023] At one end of the sleeve 10 near the retaining ring 20, there is also a detachably connected second support ring 50. The core of the second support ring 50 has an inner conical surface that mates with the outer conical surface of the workpiece. The outer periphery of the second support ring 50 is a cylindrical surface that matches the inner side surface of the sleeve 10.

[0025] During use, the workpiece 40 is loaded into the sleeve 10 from one end of the stop block 30. One end of the workpiece 40 close to the retaining ring 20 abuts against the second support ring 50, so that the outer conical surface of the end of the workpiece 40 matches the inner conical surface of the second support ring 50. Then, a set of screws pass through the sleeve 10 and are connected to the second support ring 50, and the second support ring 50 is fixed in position by tightening. At this time, the stop block 30 can be installed at the end of the sleeve 10 and the stop block 30 abuts against the end face of the workpiece 40 to limit the degree of freedom of the workpiece 40. Then, the axial position of the first support ring 60 is adjusted along the first waist-shaped hole 12, so that the inner conical surface of the first support ring 60 matches the outer conical surface of the workpiece 40. Then, the first support ring 60 is connected by screws passing through the sleeve 10 and fixed in position by tightening. Then, a stable support for the workpiece is formed.
