Description
Technical Field
[0001] This application relates to the technical field of transportation protection of motor components, and in particular to a fixing tooling. Background Art
[0002] The rotor is an important part of the motor. Generally, after the rotor is produced, it needs to be transported to a designated location for assembly.
[0003] As the core component of the motor, the rotor has a complex and precise structure, including key components such as shafts, bearings, and magnetic poles. During transportation, if the rotor is impacted, squeezed, or vibrated, it may cause damage or deformation of these components, thereby affecting the overall performance and lifespan of the motor. Therefore, appropriate protective measures are needed to protect the rotor from damage.
[0004] Currently, in order to protect different types of rotors from damage during transportation, a base with a clamping structure is generally used. The clamping structure is slidably connected to the base. The rotor is clamped by two clamping structures, and a clamping member is provided to clamp the clamping structure on the base. However, due to the heavy weight of the rotor and the possible vibration during transportation, since the contact surface between the clamping structure and the base is a smooth surface and the relative friction is small, the clamping structure may become loose, causing damage to the rotor.

A clamping member for fixing the limiting block is further provided between any one of the limiting blocks and the base.
[0008] By adopting the above technical solutions, the friction between the limiting block and the base is increased through the clamping member and the clamping structure, so that the limiting can fix the rotor more stably and is not easily loosened. The setting of the limiting block can adapt to rotors of different sizes, enhancing the adaptability of the tooling.
[0009] Preferably, a sliding track for the sliding of the limiting block is provided on the base. A clamping groove matching the sliding track is opened on the limiting block. The limiting block and the base form a sliding fit through the clamping groove and the sliding track.

[0013] Preferably, a flexible film for protecting the rotor is provided on the limit block, and the flexible film forms an abutting fit with the rotor.
[0014] By adopting the above technical solution, the limit block is prevented from directly contacting the rotor, the vibration of the rotor during transportation is reduced, and the rotor is effectively protected from damage.
[0015] Preferably, a slide groove is also provided on the base, and the slide groove is horizontally arranged along the length direction of the slide. The clamping member includes a clamping bolt and a clamping block. The clamping block is located in the slide groove and forms a sliding fit with the slide groove. The clamping bolt is rotatably connected to the limit block and is threadedly connected to the clamping block.
[0016] By adopting the above technical solution, the clamping bolts and the clamping blocks are used to facilitate the control of the clamping force between the limit block and the base, thereby enhancing the fixing effect of the tooling on the rotor and improving safety.
[0017] Preferably, the slide groove is divided into an upper groove and a lower groove, the clamping block is arranged in the lower groove, the clamping block is slidably matched with the lower groove, the clamping block is arranged as a polygonal block, the maximum diagonal length of the clamping block is greater than the width of the lower groove to limit the circumferential rotation of the clamping block, and the tail of the clamping bolt passes through the upper groove and is threadedly connected to the clamping block.
[0018] By adopting the above technical solution and controlling the circumferential rotation of the clamping block, the limit block and the base can be clamped more conveniently.
[0019] Preferably, scale lines are also provided on the slideway.
[0020] By adopting the above technical solution, the design of the scale line makes the adjustment of the limit block more precise, adapts to rotors of different lengths, and improves the universality and practicality of the clamping tooling.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0032] The following is a further detailed description of the present application in conjunction with the attached Figure 1 - attached Figure 4 drawings.
[0033] An embodiment of the present application discloses a fixing tooling.
[0034] Refer to Figure 1 and Figure 2, A fixing tooling, comprising a base 1, on which a limiting structure for fixing a rotor is provided. The limiting structure includes two oppositely arranged limiting blocks 2, which are slidably connected to the base 1. A clamping space for clamping the rotor is formed between the two limiting blocks 2. There are multiple limiting structures. A clamping structure 3 is provided on any one of the limiting blocks 2 and the base 1, and a clamping member 4 is further provided between any one of the limiting blocks 2 and the base 1.
[0035] In an embodiment of the present application, one limiting block 2 corresponds to two sliding grooves 11. Two clamping grooves 21 are correspondingly opened on one limiting block 2, and a clamping member 4 is respectively arranged at both ends of the limiting block 2.
[0036] Since the structures of any one of the limiting blocks 2 are the same, one of the limiting blocks 2 will be taken as an example for description.
[0037] Refer to Figure 1 and Figure 4 , A sliding groove 11 for the sliding of the limiting block 2 is provided on the base 1. A clamping groove 21 matching the sliding groove 11 is further opened on the limiting block 2. The limiting block 2 is clamped and connected to the sliding groove 11 through the clamping groove 21. The limiting block 2 and the base 1 form a sliding fit through the clamping groove 21 and the sliding groove 11. The clamping structure 3 is respectively arranged on the abutting surfaces of the clamping groove 21 and the sliding groove 11, and the rack of the clamping groove 21 and the sliding groove 11 forms a meshing fit to increase the friction force.
[0038] Refer to Figure 1 and Figure 3 , A chute 12 is further provided on the base 1. The chute 12 is horizontally arranged along the length direction of the sliding groove 11. The cross-sectional shape of the chute 12 is "convex" and both ends are open. The chute 12 is divided into an upper chute 121 and a lower chute 122. The clamping member 4 includes a clamping bolt 41 and a clamping block 42. The clamping bolt 41 is threadedly connected to the limiting block 2. The clamping block 42 is arranged in the lower chute 122 of the chute 12 through the openings at both ends of the chute 12 and forms a sliding fit with the lower chute 122. The tail of the clamping bolt 41 passes through the upper chute 121 and is threadedly connected to the clamping block 42 in the lower chute 122. The clamping block 42 is set as a multi-faceted block, and the maximum diagonal length of the clamping block 42 is greater than the width of the lower chute 122. When the clamping bolt 41 is rotated, the lower chute 122 will limit the clamping block 42 to ensure that the clamping block 42 will not rotate circumferentially during the adjustment process.
[0039] Refer to Figure 1 and Figure 4, in order to reduce the damage to the rotor during transportation, a flexible film 5 is also provided on the limiting block 2. The flexible film 5 forms an abutting fit with the rotor. In the embodiment of the present application, the flexible film 5 is made of TPU material, which is wear-resistant and can prevent chip shedding during use. The flexible film 5 includes a horizontal plane 51 and a vertical plane 52. During installation, first place the rotor on the horizontal plane 51 of the flexible film 5 of the oppositely arranged limiting blocks 2, and then adjust the position of the limiting block 2 so that both the vertical plane 52 and the horizontal plane 51 are in contact with the rotor, and then tighten the clamping bolt 41 to fix the rotor.
[0040] Refer to Figure 1 and Figure 2 , a scale line 6 is provided on the slideway 11. The scale line 6 can accurately observe the position of the limiting block 2 to ensure the adjustment accuracy of the limiting block 2.
[0041] Refer to Figure 1 and Figure 4 , in order to reduce the overall weight of the tooling without affecting its structural strength, the limiting block 2 is provided with a groove 7 for weight reduction, and the setting of the groove 7 makes the limiting block 2 in an arched shape, increasing the structural strength of the limiting block 2. The bottom of the limiting block 2 abuts against the upper surface of the base 1 to increase the bearing capacity.
[0042] The implementation principle of the embodiment of the present application is as follows: during use, according to the size of the rotor, adjust the position of the limiting block 2 through the cooperation of the slideway 11 and the clamping groove 21, and perform stable clamping through the engagement of the rack; then place the rotor between the limiting blocks 2 to ensure its stability; subsequently, place the clamping block 42 into the lower groove 122 from the openings at both ends of the sliding groove 12, and tighten the clamping bolt 41. At this time, the flexible film 5 closely adheres to the rotor to provide protection for it and prevent damage. In this way, the tooling can effectively fix and protect rotors of different sizes and reduce possible damage during transportation.
[0043] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
