[0023] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Embodiment 1
[0025] See also Figure 1-Figure 5The utility model provides a technical solution: a steel ball size screening jig, comprising: a mounting frame 1 and a handle 9, one end of the handle 9 is threadedly mounted on a side wall of one end of the mounting frame 1, a rubber anti-slip sleeve is sleeved on the outer wall of the handle 9, a threaded tube 5 is fixedly mounted on the outer wall of one end of the mounting frame 1, a threaded column 10 is provided at one end of the handle 9, the threaded column 10 and the handle 9 are a whole, an external thread is provided at the front end of the threaded column 10, the threaded column 10 is shaped like the threaded column 10, the outer wall of the threaded column 10 and the inner wall of the threaded tube 5 are threadedly connected, so that the handle 9 is fixed on the outer wall of the mounting frame 1, which plays a role in convenient disassembly and assembly, the mounting frame 1 is in a mouth shape, and a placement groove 2 is provided at the upper end of the mounting frame 1, the inner diameter of the placement groove 2 is slightly larger than the size of the sieve plate 11, and the sieve plate 11 can be placed in the placement groove 2.
[0026] The upper end of the sieve plate 11 is evenly provided with a plurality of grooves of equal size. The sieve plate 11 is inserted into a container filled with steel balls and then lifted upward, and steel balls of the appropriate size will enter the grooves, thereby quickly screening out the steel balls of the appropriate size.
[0027] Circular holes 4 are provided on the front and rear sides of one end of the mounting frame 1, and the two circular holes 4 are respectively located on the front and rear sides of the threaded tube 5, and the circular holes 4 are connected to the placement groove 2. A limiting groove 3 is provided on the inner side of the other end of the placement groove 2. Limiting holes 12 are provided on the front and rear sides of one end of the sieve plate 11, and a rubber strip 13 is fixedly installed on the side wall of the other end. By placing the sieve plate 11 in the placement groove 2 and then pressing it down, one end of the rubber strip 13 is pressed into the limiting groove 3, so that one end of the sieve plate 11 is limited.
[0028] The front and rear sides of one end of the mounting frame 1 are elastically connected to the limit pin 6, one end of the limit pin 6 passes through the mounting frame 1 and is connected to one end of the sieve plate 11, and the limit pin 6 is slidably connected in each circular hole 4. A pull ring 8 is fixedly installed on the outer wall of one end of the limit pin 6, and a spring 7 is sleeved on the outer wall of the other end of the limit pin 6. Both ends of the spring 7 are respectively fixedly installed on the limit pin 6 and the outer wall of the mounting frame 1. When the spring 7 is in a balanced state, the other end of the limit pin 6 passes through the circular hole 4 and is inserted into the limit hole 12, thereby fixing the other end of the sieve plate 11.
[0029] When it is necessary to screen steel balls of different specifications, it is only necessary to replace the sieve plate 11 with grooves of different inner diameters. By hooking the pull ring 8 with two fingers and pulling it outward, the limit pin 6 is pulled outward by stretching the spring 7 and separated from the limit hole 12, the sieve plate 11 can be pushed out from the other end of the installation frame 1, which is convenient for disassembly and assembly of the sieve plate 11.
[0030] In actual use, according to the diameter of the steel balls to be screened, a suitable sieve plate 11 is selected, and the sieve plate 11 is installed in the installation frame 1, and then the sieve plate 11 is inserted into a container filled with steel balls, and then lifted upward, the steel balls that meet the size will enter the groove, so that the steel balls that meet the size can be quickly screened out. Embodiment 2

[0033] In actual use, a suitable sieve plate 11 is selected according to the diameter of the steel balls to be screened, and the sieve plate 11 is installed in the installation frame 1. The sieve plate 11 is then inserted into a container filled with steel balls and then lifted up. Steel balls that meet the size will enter the groove, thereby quickly screening out the steel balls that meet the size.
