[0016] Example: See Figure 1 - Figure 4 The utility model provides a technical solution: a shell processing tooling that is easy to fix, including: a support seat 1, a positioning pin 2, a rotating bolt 3, a clamping plate 4; an internal support device 5, the internal support device 5 is used to fix the shell, and the bottom of the internal support device 5 is fixedly connected to the top of the support seat 1; a fixed seat 6, the top of the fixed seat 6 is in contact with the bottom of the support seat 1; a positioning device 7, the positioning device 7 is used to assist the installation of the support seat 1, and the bottom of the positioning device 7 is fixedly connected to the top of the fixed seat 6; a push plate 8, the outer wall of the push plate 8 is slidably connected to the inner wall of the support seat 1; the internal support device 5 includes a fixed cylinder 51, the inner wall of the fixed cylinder 51 is slidably connected with a movable column 55, the inner wall of the fixed cylinder 51 is rotatably connected with a rotating bar 52, the inner wall of the rotating bar 52 is slidably connected to a limiting block 54 through a movable groove 53, and the movable groove 53 is opened in the wall of the rotating bar 52, and the limiting The outer wall of block 54 is fixedly connected to the outer wall of movable column 55, and the bottom of movable column 55 is fixedly connected with compression spring 56. When the shell approaches the support seat 1, the shell will squeeze the movable column 55, so that the movable column 55 squeezes the compression spring 56, and at the same time drives the limit block 54 to move downward. Since the limit block 54 will slide in the movable groove 53 during the descent, due to the shape setting of the movable groove 53, the limit block 54 will push the rotating bar 52 to move. Since the bottom of the rotating bar 52 is rotatably connected to the fixed cylinder 51, the top of the rotating bar 52 will move outward from the fixed cylinder 51. The raised part on the top of the rotating bar 52 is flexible and has deformation ability, and the rest is rigid. Therefore, when the rotating bar 52 rotates outward, the flexible rotating bar 52 will resist the inner wall of the circular hole of the shell, making it difficult for the shell to shake on the plane of the support seat 1.

[0017] The top of the support seat 1 is fixedly connected with a positioning pin 2, the inner wall of the positioning pin 2 is rotatably connected with a clamping plate 4, the outer surface of the clamping plate 4 is slidably connected with a rotating bolt 3, the outer wall of the rotating bolt 3 is threadedly connected to the inner wall of the support seat 1, the bottom of the fixed tube 51 is fixedly connected to the top of the support seat 1, the bottom of the support seat 1 is in contact with the top of the compression spring 56, and the rotating bolt 3 is twisted so that the nut position of the rotating bolt 3 squeezes the clamping plate 4 on the positioning pin 2, and the clamping plate 4 squeezes the shell downward. Through the extrusion force, the shell can squeeze the movable column 55 more stably, thereby further improving the ability of the internal support device 5 to prevent the shell from shaking.

[0018] The positioning device 7 includes a fixed plate 71, the inner wall of the fixed plate 71 is slidably connected to a slider 72, the outer wall of the slider 72 is fixedly connected to a force storage spring 73, the top of the outer wall of the slider 72 is fixedly connected to a push block 74, the outer wall of the push block 74 is slidably connected to a positioning block 75, the end of the positioning block 75 close to the slider 72 is fixedly connected to a tension spring 76, the end of the tension spring 76 away from the positioning block 75 is fixedly connected to the inner wall of the fixed plate 71, the bottom of the fixed plate 71 is fixedly connected to the top of the fixed seat 6, the side wall of the fixed plate 71 is slidably connected to the inner wall of the support seat 1, and the support seat 1 is placed During the process on the fixed seat 6, the support seat 1 will squeeze the inclined surface on the slider 72, so that the slider 72 squeezes the force storage spring 73. At the same time, the pushing blocks 74 on the slider 72 approach each other and push the positioning block 75, so that the positioning block 75 is away from the fixed plate 71 and pulls the tension spring 76. When the support seat 1 is completely in contact with the top of the fixed seat 6, the positioning block 75 is pushed out and enters the interior of the support seat 1. Due to the mutual contact between the side walls of the fixed plate 71 and the grooves on the inner wall of the support seat 1, a positioning effect is achieved, making it difficult for the support seat 1 to shake on the plane of the fixed seat 6.

[0019] Working principle:

[0020] When in use, an inner support device 5 is provided to prevent the shell from shaking. Before the shell is processed, the inner support device 5 is fixed in advance under the circular hole of the shell. When the shell is placed on the support seat 1, the circular hole is aligned with the inner support device 5. Since the top of the circular hole of the shell is closed, when the shell is close to the support seat 1, the shell will squeeze the movable column 55, so that the movable column 55 squeezes the compression spring 56, and at the same time drives the limit block 54 to move downward. Since the limit block 54 will slide in the movable groove 53 during the descent process, due to the shape setting of the movable groove 53, the limit block 54 will push the rotating bar 52 to move. Since the bottom of the rotating bar 52 is rotatably connected to the fixed cylinder 51, the top of the rotating bar 52 will move out of the fixed cylinder 51. The raised part on the top of the rotating bar 52 is flexible. The cam 55 is a spring loaded part that is used to hold the cam 55 in place and to hold the cam 55 in place until the cam 52 is within reach.

[0021] The positioning device 7 is provided so that the support seat 1 can be quickly fixed. The support seat 1 has four mutually symmetrical grooves, and the positioning device 7 has four and is also symmetrically arranged on the fixing seat 6. The purpose of quickly positioning the support seat 1 is achieved by the four positioning devices 7 and the four grooves corresponding to each other. In the process of placing the support seat 1 on the fixing seat 6, the support seat 1 will squeeze the inclined surface on the slider 72, so that the slider 72 squeezes the storage spring 73. At the same time, the pushing blocks 74 on the slider 72 approach each other and push the positioning blocks 75, so that the positioning blocks 75 are away from the fixing plate 71 and pull the tension spring 76. When the support seat 1 is completely in contact with the top of the fixing seat 6, the positioning block 75 is pushed out and enters the inside of the support seat 1. Due to the mutual contact between the side walls of the fixing plate 71 and the grooves on the inner wall of the support seat 1, the positioning effect is achieved, making it difficult for the support seat 1 to shake on the plane of the fixing seat 6, and the positioning block 75 enters the support seat 1 to push the push plate 8 outward toward the support seat 1, so that the push plate 8 extends out to provide support, which is convenient for the subsequent lifting of the support seat 1 from the fixing seat 6.
