[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Implementation Method

[0024] See also Figure 1 -3. High-performance rack, comprising: a main body 1 and a limiting rod 8, wherein a plurality of gear teeth 2 are fixedly connected to the upper surface of the main body 1;

[0025] A limiting groove 6 is formed at the bottom of the main body 1, and a limiting rod 8 is clamped inside the limiting groove 6;

[0026] The inner thread of the limiting rod 8 is connected with a fixing screw 7 , and the end of the fixing screw 7 is threadedly connected to the interior of the main body 1 .

[0027] The technical solution provided by this embodiment is as follows: during manufacturing, the material is preferably high-strength alloy steel, and then a milling machine is used to mill the general shape of the rack and the limiting groove 6, the mounting hole 3 and other parts, and then the rack is heat treated. After the heat treatment, the rack is ground. First, the surface of the rack is cleaned to remove oil and rust, etc., and then the speed, pressure and feed rate during grinding are determined. During the grinding process, coolant should be continuously output to the surface of the rack to avoid deformation due to heat, which may affect the performance of the rack. Then, a cloth wheel and abrasive paste are used to polish the rack to remove the remaining fine burrs, and then the rack is cleaned. , remove coolant and other substances remaining on the surface, then paint or electroplate the surface of the rack to avoid treatment, increase acid and alkali resistance and corrosion resistance. After manufacturing is completed, when using it, first measure the length of the working area, then select the correct number of racks, and then fix the first main body 1 through the mounting hole 2. Next, clamp the connecting groove 5 of the next main body 1 on the outer wall of the connecting block 4, and then fix it through the mounting hole. The subsequent racks are installed according to this step. After all the racks are installed, place the limiting rod 8 into the limiting groove 6 at the connection of the two main bodies 1, and then fix it with the fixing screw 7.

[0028] Furthermore, two mounting holes 3 are provided inside the main body 1 .

[0029] Specifically, the provision of the mounting hole 3 makes it more convenient to install the rack at the work station.

[0030] Furthermore, a connection groove 5 is formed at one end of the main body 1 , and a connection block 4 is fixedly connected to the other end of the main body 1 .

[0031] Specifically, the connection grooves 5 and the connection blocks 4 are respectively provided on both sides of the main body 1, so that the device can be installed at a suitable length at any time when in use.

[0032] Furthermore, the connecting block 4 is plugged into the inner wall of the connecting groove 5 .

[0033] Specifically, it is inserted into the connecting groove 5 to ensure the structural strength of the multiple racks when connected, and to avoid accidental damage during operation due to insufficient strength.

[0034] Furthermore, the tooth roots and tooth tops of the rack teeth 2 are both rounded.

[0035] Specifically, the rounded corners reduce the concentrated stress of the rack, improve the wear resistance of the rack, and increase the smoothness of the meshing.

[0036] Furthermore, the pressure angle of the rack teeth 2 is 17.5° to 20°.

[0037] Specifically, the pressure angle setting of 17.5°~20° increases the overlap between the rack and the gear during operation, reduces noise, and improves transmission stability.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
