[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0024] Reference Figure 1-3 , a stable limit tooling for processing aluminum disc of lawn mower, comprising a limit seat 1, a limit mechanism installed on the limit seat 1, the limit mechanism comprising a moving ring 2, a clamping part 3, a threaded barrel 5, a stud 6, a limit head 8 and an elastic part 9, the moving ring 2 is elastically connected to the limit seat 1 through a spring 4, the clamping part 3 is hinged at the edge of the limit seat 1 in multiple groups, and one end thereof is embedded in the annular groove on the side of the moving ring 2, the threaded barrel 5 is fixedly installed on the limit seat 1, the stud 6 runs through the middle of the moving ring 2, and is rotatably connected to the threaded barrel 5, the elastic part 9 is fixedly installed in the top groove of the moving ring 2, and the limit head 8 is rotatably installed on the upper end of the stud 6;

[0025] Three groups of notches are provided at the edge of the limit seat 1, and three groups of clamping parts 3 are hinged in the notches. The clamping part 3 is an L-shaped structure as a whole. When the moving ring 2 presses the end of the clamping part 3, its upper end can move centripetally to limit the edge of the aluminum plate, and the limit head 8 moves downward synchronously to open the upper end of the elastic part 9, and then the elastic part 9 can expand to tighten and limit the middle part of the aluminum plate.

[0026] A toggle rod 7 can be movably inserted into the upper end of the stud 6; the upper and lower ends of the stud 6 are both arranged with a threaded structure, and the middle part is arranged with a cylindrical structure, and a flange 601 is installed in the middle part, and the flange 601 fits in the groove at the top of the movable ring 2; a circular hole is opened at the upper end of the stud 6, and the diameter of the circular hole is adapted to the diameter of the toggle rod 7. The toggle rod 7 can be directly inserted into the circular hole, and the stud 6 can be assisted by the toggle rod 7 to rotate. When the stud 6 rotates downward in the threaded barrel 5, the stud 6 can synchronously drive the limit head 8 to move downward, and the lower end of the limit head 8 is inserted into the upper end of the elastic part 9 to open the upper end of the elastic part 9, so that the elastic part 9 can tighten the middle hole of the aluminum plate, and the flange 601 in the middle can press the movable ring 2 downward. After the stud 6 is rotated in the opposite direction, the flange 601 reduces the pressure on the movable ring 2 and will move upward through the spring 4 to return to its original position.

[0027] The limit seat 1 is also equipped with three sets of convex plates 101 arranged around it for supporting the aluminum plate; the thickness of the convex plates 101 can be adjusted according to the thickness of the aluminum plate to ensure that the aluminum plate can be limited while its upper end surface protrudes from the limit seat 1 for better processing.

[0028] The limiting head 8 is in the form of a truncated cone structure as a whole; the limiting head 8 can be driven to open the upper end of the elastic part 9.

[0029] The upper end of the elastic part 9 is arranged with three spaced elastic sheet structures, and the lower end is fixed on the movable ring 2; after the limit head 8 stretches the upper end of the elastic part 9, the elastic part 9 fits in the middle of the aluminum plate, and the aluminum plate is positioned from the middle of the aluminum plate.

[0030] Working principle: the aluminum plate of the lawn mower can be placed on the limit seat 1 and supported by the convex plate 101. At this time, the middle hole of the aluminum plate of the lawn mower is sleeved on the outside of the elastic part 9. Then the limit head 8 is rotated and installed on the stud 6 so that the lower end of the limit head 8 fits the inner side of the elastic part 9. Then the toggle rod 7 is inserted and the stud 6 is rotated. During the process of the stud 6 rotating downward inside the threaded tube 5, the upper end of the elastic part 9 will be supported by the limit head 8. The upper end of the elastic part 9 will expand outward and restrict the aluminum plate of the lawn mower from the middle hole of the aluminum plate of the lawn mower. At the same time, the flange 601 in the middle of the stud 6 can push the movable ring 2 to move downward. The movable ring 2 synchronously drives one end of the three groups of clamping parts 3 to move downward, and the upper ends of the three groups of clamping parts 3 will move centripetally, so that the edge of the aluminum plate of the lawn mower can be positioned. At this time, the aluminum plate of the lawn mower will be stably limited on the tooling.

[0031] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
