It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4 As shown, this utility model provides a high-precision machined irregular steel part, including: an irregular base 1, a liner body 6 on the top of the irregular base 1, second mounting holes 10 symmetrically opened on the bottom of the liner body 6, fixing posts 3 symmetrically fixedly connected to the inner bottom of the irregular base 1, the fixing posts 3 being located inside the second mounting holes 10, and hexagon socket head cap screws 9 threadedly connected to the inner surfaces of the two fixing posts 3, first mounting holes 4 symmetrically opened on the outer surface of the irregular base 1, first mounting grooves 5 symmetrically opened on the inner bottom of the irregular base 1, the first mounting grooves 5 communicating with the first mounting holes 4, second mounting grooves 11 symmetrically opened on the top of the liner body 6, the second mounting grooves 11 communicating with the second mounting holes 10, the outer surface of the hexagon socket head cap screws 9 fitting with the inner surface of the second mounting grooves 11, the top of the hexagon socket head cap screws 9 being on the same plane as the top of the liner body 6, the cross-section of the liner body 6 being T-shaped, and the outer surface of the liner body 6 fitting with the outer surface of the irregular base 1.

[0023] The effect achieved by the whole embodiment 1 is that when installing the lining plate in the mine stirring machine, the first installation hole 4 is symmetrically arranged on the surface of the special-shaped base 1, which is convenient for the fastening bolt to pass through from the inside and penetrate the machine body, so that the screw rod of the fastening bolt extends to the outside of the machine body, and the head of the fastening bolt is located in the first installation groove 5. By threadedly connecting the matched nut on the extended screw rod, the special-shaped base 1 can be fixed to the inside of the stirring machine. The special-shaped base 1 and the lining plate body 6 are machined with high precision, which facilitates the embedding of the two without large gaps. By symmetrically fixing the fixing column 3 on the top of the special-shaped base 1, when the lining plate body 6 is embedded on the surface of the special-shaped base 1, the fixing column 3 will be inserted into the second installation hole 10, and the lining plate body 6 will be fixed and installed on the top of the special-shaped base 1 by threadedly connecting the fixing column 3 with the internal hexagonal bolt 9. By symmetrically arranging the second installation groove 11 on the top of the lining plate body 6, the head of the connected internal hexagonal bolt 9 will not protrude outward. When the lining plate body 6 needs to be replaced, only two internal hexagonal bolts 9 need to be unscrewed from the inside of the stirring machine, so that the personnel can replace the lining plate body 6 inside the stirring machine without the cooperation of two people, reducing the number of maintenance personnel and greatly reducing the maintenance cost.

[0024] Embodiment 2: As shown in Figures 1-4 The lining plate body 6 is symmetrically fixedly connected with a plurality of positioning rods 8 on the inner top, the top of the special-shaped base 1 is symmetrically provided with a plurality of positioning holes 2, the positioning holes 2 and the positioning rods 8 are in matched arrangement, the bottom of the lining plate body 6 is provided with a rubber pad 7, and the bottom of the special-shaped base 1 is arc-shaped.

[0025] The effect achieved by the whole embodiment 2 is that when the lining plate body 6 is installed and fixed, the rubber pad 7 is arranged at the bottom of the lining plate body 6, which is convenient for the lining plate body 6 to be fixed by using the deformation characteristics of the rubber pad 7 under extrusion to increase the connection effect between the special-shaped base 1 and the lining plate body 6. The plurality of positioning rods 8 symmetrically connected on the inner top of the lining plate body 6 are inserted into the corresponding positioning holes 2, which plays a positioning role and increases the stability of the lining plate body 6 after installation, so that the lining plate body 6 is not easy to shake.

[0026] Working principle: when installing the lining plate in the mine stirring machine, the first installation hole 4 is symmetrically arranged on the surface of the special-shaped base 1, which is convenient for the fastening bolt to pass through from the inside and penetrate the machine body, so that the screw rod of the fastening bolt extends to the outside of the machine body, and the head of the fastening bolt is located in the first installation groove 5. The special-shaped base 1 and the lining plate body 6 are processed by high-precision machining, which can prevent large gaps from occurring when the two are embedded. The fixed column 3 is symmetrically fixed and connected on the top of the special-shaped base 1, which can be inserted into the second installation hole 10 when the lining plate body 6 is embedded on the surface of the special-shaped base 1. The lining plate body 6 is fixed and installed on the top of the special-shaped base 1 by the way of screwing the inner hexagonal bolt 9 with the fixed column 3. The second installation groove 11 is symmetrically arranged on the top of the lining plate body 6, which can prevent the head of the connected inner hexagonal bolt 9 from protruding outward. When the lining plate body 6 needs to be replaced, only two inner hexagonal bolts 9 need to be unscrewed from the inside of the stirring machine, so that the lining plate body 6 can be replaced inside the stirring machine without the cooperation of two people, reducing the number of maintenance personnel and greatly reducing the maintenance cost. When the lining plate body 6 is installed and fixed, the rubber pad 7 is arranged at the bottom of the lining plate body 6, which can increase the connection effect between the special-shaped base 1 and the lining plate body 6 by using the deformation characteristics of the rubber pad 7 under pressure when the lining plate body 6 is fixed. The plurality of positioning rods 8 symmetrically connected on the inner top of the lining plate body 6 are inserted into the corresponding positioning holes 2, which can play a positioning role and increase the stability of the lining plate body 6 after installation, so that the lining plate body 6 is not easy to shake.
