Description

Technical Field

[0001] The utility model relates to the technical field of magnetic drive production, in particular to a magnetic drive processing tool. Background Art

[0002] Magnetic drive is a technology that uses the basic theory of modern magnetism to apply the magnetic force generated by permanent magnetic materials or electromagnets to achieve contactless transmission of force or torque (power). The device that implements this technology is called a magnetic drive, or magnetic transmission, magnetic coupler, magnetic coupling, etc.

[0003] A magnetic drive primarily consists of an inner drive shaft, an inner magnetic rotor, an isolation cover, and an outer magnetic rotor. The inner magnetic rotor is mounted on the outer end of the inner drive shaft, the isolation cover is mounted on the outer end of the inner magnetic rotor, and the outer magnetic rotor is mounted on the outer end of the isolation cover. During the manufacturing process of the magnetic drive, the isolation cover and the inner drive shaft are prone to misalignment, which can seriously affect the final quality and accuracy of the magnetic drive. Although an inspection process is implemented after the isolation cover is assembled, this process currently relies primarily on manual visual inspection, resulting in low accuracy and prone to missed inspections. This results in low production consistency and a low pass rate for magnetic drives.

[0004] Therefore, it is urgent to propose a magnetic drive processing tooling to solve the above technical problems. Utility Model Content

Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0035] This embodiment provides a magnetic drive processing tooling, which can position the installation between the isolation cover and the inner transmission shaft, improve the installation accuracy between the isolation cover and the inner transmission shaft, and thus improve the production consistency and production qualification rate of the magnetic drive.

[0036] Specifically, if Figure 1-Figure 4 As shown, the magnetic drive processing tooling includes a base 100 , a first limiting seat 200 , a second limiting seat 300 and a third limiting seat 400 .

[0037] Among them, the base 100 is provided with a first angle limit portion and a second angle limit portion. The first limit seat 200 is arranged on the base 100, and the isolation cover 20 is sleeved on the outside of the first limit seat 200. The isolation cover 20 is provided with a first matching portion, and the first matching portion is used to cooperate with the first angle limit portion to limit the rotation of the isolation cover 20. The second limit seat 300 is arranged on the first limit seat 200, and the second limit seat 300 is used to support the inner transmission shaft 10 to limit the height position between the inner transmission shaft 10 and the isolation cover 20. The third limit seat 400 is arranged on the second limit seat 300, and the third limit seat 400 is coaxially arranged with the first limit seat 200. The inner transmission shaft 10 is sleeved on the outside of the third limit seat 400 through the center hole and abuts against the top of the second limit seat 300. The inner transmission shaft 10 is provided with a second matching portion, and the second matching portion is used to cooperate with the second angle limit portion to limit the rotation of the inner transmission shaft 10.

[0038] The method steps for assembling the isolation cover 20 and the inner transmission shaft 10 using the magnetic drive processing tool are as follows:

[0039] First, align the center hole of the inner transmission shaft 10 with the third limiting seat 400, then move the inner transmission shaft 10 so that the third limiting seat 400 enters the center hole, and after the inner transmission shaft 10 abuts against the top of the second limiting seat 300, rotate the inner transmission shaft 10 so that the second matching portion on the inner transmission shaft 10 matches the first angle limiting portion on the base 100, thereby fixing the inner transmission shaft 10;

[0040] Then, the isolation cover 20 is put on the first limiting seat 200 until the isolation cover 20 abuts against the base 100 and then rotated to make the first matching portion on the isolation cover 20 match the first angle limiting portion on the base 100 to fix the isolation cover 20.

[0041] Finally, the isolation cover 20 and the inner transmission shaft 10 are locked and assembled together.

[0042] When using this magnetic drive processing tool to assemble the isolation cover 20 and the inner transmission shaft 10, the coaxiality, relative angle, and relative height between the isolation cover 20 and the inner transmission shaft 10 can be guaranteed to meet the processing accuracy, thereby improving the production consistency and production qualification rate of the magnetic drive. In addition, it can simplify the assembly process between the isolation cover 20 and the inner transmission shaft 10 and improve assembly efficiency.

[0043] Optionally, the base 100 , the first limiting seat 200 , the second limiting seat 300 and the third limiting seat 400 are coaxially arranged, which facilitates processing.

[0044] Optionally, the base 100 , the first limiting base 200 , the second limiting base 300 and the third limiting base 400 may be an integrated structure.

[0045] Optionally, in a possible embodiment, the first limit seat 200 is cylindrical, and the outer peripheral wall of the first limit seat 200 is in contact with the inner peripheral wall of the isolation cover 20. Such an arrangement enables the first limit seat 200 to have a better limiting effect on the axial position of the isolation cover 20, thereby improving the centering between the isolation cover 20 and the inner transmission shaft 10.

[0046] Alternatively, in another possible embodiment, the third stopper 400 is cylindrical, with the outer circumferential wall of the third stopper 400 abutting against the inner circumferential wall of the center hole. This arrangement allows the third stopper 400 to better limit the axial position of the inner transmission shaft 10, thereby improving the alignment between the isolation cover 20 and the inner transmission shaft 10.

[0047] Further, see Figure 3 , the top of the third limiting seat 400 is not lower than the top of the inner transmission shaft 10. With this arrangement, the limiting effect is better.

[0048] Further, see Figure 4 The first angle limiting portion includes a positioning rod 110 provided on the base 100, and the first matching portion includes a matching positioning hole provided on the isolation cover 20, which is used to be plugged into the positioning rod 110. The circumferential positioning of the isolation cover 20 is achieved through the cooperation between the positioning rod 110 and the matching limiting hole, which has a simple structure and convenient positioning.

[0049] Optionally, multiple positioning rods 110 may be provided, and the multiple positioning rods 110 may be spaced apart along the circumference of the base 100. For example, in this embodiment, two positioning rods 110 are provided, and the two positioning rods 110 are spaced apart by 30° along the circumference of the base 100. The smaller number of positioning rods 110 facilitates processing and improves positioning effectiveness. Of course, in other embodiments, the number and arrangement of positioning rods 110 may be other, as required.

[0050] It is worth noting that each positioning rod 110 is correspondingly provided with a matching positioning hole.

[0051] Further, see Figure 2 and Figure 4 The outer peripheral wall of the base 100 includes an arc segment 130 and a straight segment 120 connected to the arc segment 130. The straight segment 120 serves as the second angle limiter. The second mating portion is a connector 11 disposed on the outer peripheral wall of the inner transmission shaft 10. The connector 11 extends radially along the inner transmission shaft 10 and is disposed perpendicular to the straight segment 120. The mating of the connector 11 and the straight segment 120 achieves circumferential fixation of the inner transmission shaft 10, resulting in a simple structure and convenient positioning.

[0052] It is worth noting that the connecting piece 11 on the inner transmission shaft 10 is used to connect the inner transmission shaft 10 with other components.

[0053] Optionally, a limiting flange (not shown) is provided on the outer ring of the first limiting seat 200 on the base 100, and the outer peripheral wall of the isolation cover 20 is in contact with the limiting flange. The limiting flange and the first limiting seat 200 can clamp the isolation cover 20, thereby improving the positioning effect of the magnetic drive processing tool on the isolation cover 20, and further facilitating the improvement of the assembly accuracy between the isolation cover 20 and the inner transmission shaft 10.

[0054] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
