Description

Technical Field

[0001] This invention relates to the technical field of power tool testing, specifically to a HALF-type coaxiality bidirectional adjustment method and its structure. Background Technology

[0002] When adjusting the radial and axial coaxiality of existing HALF-type plastic housings, the positional deviation direction and amount of the bearing housing are generally determined by actual assembly. However, this is largely based on subjective judgment without data support, which further complicates the confirmation of actual orientation, especially when both directions need to be confirmed simultaneously. Furthermore, when high coaxiality requirements are involved for multiple (axial and radial) bearing housings, the determination of the direction during actual assembly is often vague, inaccurate, time-consuming, requires repeated mold repairs, and increases mold costs.

[0003] Existing testing methods and equipment make it difficult to accurately measure actual dimensions. Even if a single dimension can be measured, it is difficult to measure the specific direction and deviation of the offset. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a HALF-type coaxiality bidirectional adjustment method and device to solve the problems mentioned in the background art.

[0005] The above-mentioned objective of the present invention is achieved through the following technical solution:

[0006] A half-type coaxiality bidirectional adjustment structure includes two interconnected housings. A stator and a rotor are installed inside the housings. The stator and the rotor are coaxially arranged. An alignment shaft is inserted into the rotor. One end of the alignment shaft is provided with a locking block, which is locked into the housing. A drive shaft is provided on the upper side of the alignment shaft. The drive shaft and the alignment shaft are arranged parallel to each other. The drive shaft and the alignment shaft are connected through a transmission mechanism.

[0007] In a preferred embodiment, the present invention may be further configured such that: a through groove is provided on the side of the housing near the drive shaft, and the through groove is perpendicular to the drive shaft.

[0008] In a preferred embodiment, the present invention may be further configured such that the axes of the drive shaft and the alignment shaft are parallel to the splicing line of the housing.

[0009] A half-type bidirectional coaxiality adjustment method includes the following steps:

[0010] S1: Check whether the runout accuracy of the alignment axis and drive axis meets the requirements of the inspection fixture;

[0011] S2: Install the rotor and alignment shaft. The rotor and alignment shaft are located on the same axis. When the alignment shaft rotates, it is used to determine the radial misalignment and deviation between the stator and the rotor.

[0012] S3: Confirm the parallelism between the positive axis and the drive axis.

[0013] S4: After installation, before use, check whether the alignment axis and drive shaft are aligned with the splicing line. First, use the alignment axis as a reference to confirm the parallelism of the drive shaft, and then confirm the radial deviation between the alignment axis and the stator by reverse calculation.

[0014] In summary, the present invention has at least one of the following beneficial technical effects:

[0015] 1. It can clearly and intuitively reflect the direction of bearing housing misalignment;

[0016] 2. It allows for intuitive testing of dimensional deviations and the establishment of mold repair data.

[0017] 3. It can reproduce and verify whether the direction and data of the mold modification are the same as the actual assembly direction and data;

[0018] 4. It allows for a more intuitive determination of which dimensions have changed and mutual confirmation of relative positions. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-3As shown, this technical solution discloses a HALF-type coaxial bidirectional adjustment structure, comprising two interconnected housings 1, which are semi-shell type, forming the main body of the device. A stator 2 and a rotor 3 are installed inside the housing 1, coaxially arranged. An alignment shaft 4 is inserted into the rotor 3 and fixedly connected to it. This integral connection ensures greater accuracy in the connection between the alignment shaft 4 and the rotor 3. A locking block 5 is provided at one end of the alignment shaft 4, engaging within the housing 1. Since the rotor 3 rotates, the locking block 5 is also a rotating body. However, this engagement only limits its position; therefore, the locking block 5 can rotate around its own axis.

[0025] A drive shaft 6 is provided on the upper side of the alignment shaft 4. The drive shaft 6 and the alignment shaft 4 are arranged parallel to each other and are connected to the alignment shaft 4 through a transmission mechanism 7. The axes of the drive shaft 6 and the alignment shaft 4 are parallel to the splicing line 8 of the housing 1. The splicing line 8 is used to ensure that the axes of the drive shaft 6 and the alignment shaft 4 are parallel to it, and then the drive shaft 6 and the alignment shaft 4 are mutually corrected.

[0026] A through slot 9 is provided on the side of the housing 1 near the drive shaft 6. The through slot 9 is perpendicular to the drive shaft 6. The through slot 9 provided here makes it convenient to expose the drive shaft 6 and the alignment shaft 4 on the outside. At this time, the width can be measured by tools such as vernier calipers. The width here is compared with the width of the front section to check the parallelism between them.

[0027] A half-type bidirectional coaxiality adjustment method includes the following steps:

[0028] S1: Checks whether the runout accuracy of the alignment axis 4 and the drive axis 6 meets the requirements of the fixture; used to check whether the accuracy of the alignment axis 4 and the drive axis 6 themselves meets the standard.

[0029] S2: Install rotor 3 and alignment shaft 4. Rotor 3 and alignment shaft 4 are located on the same axis. When alignment shaft 4 rotates, it is used to determine the radial misalignment and deviation between stator 2 and rotor 3.

[0030] S3: Confirm the parallelism between the positive shaft 4 and the drive shaft 6 by comparing the positions at the through groove 9 and the end.

[0031] S4: After installation, before use, check whether the alignment shaft 4 and drive shaft 6 are aligned with the splicing line 8. First, take the alignment shaft 4 as the reference to confirm the parallelism of the drive shaft 6, and then confirm the radial deviation between the alignment shaft 4 and the stator 2 by reverse calculation.

[0032] This technical solution only describes the parts that require design modifications. For other parts that do not require modification, the original parts can be used, and will not be elaborated here.

[0033] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
