Description

TECHNICAL FIELD

[0001] The utility model relates to gear tool technical field, concretely is a gear shaft tooth thickness alignment subassembly. BACKGROUND

[0002] In the assembly process of the gear transmission system, external fixed clamps or positioning blocks are usually used to ensure the alignment and assembly accuracy of the gear shaft. The traditional gear assembly method usually relies on the radial clamping force exerted by external clamps to fix the position of the gear shaft, and manual adjustment is used to ensure the alignment of the tooth thickness. However, this method has the problems of complicated adjustment and low assembly efficiency. In addition, the rigid clamping method of the traditional clamp is difficult to ensure flexible adjustment of different specifications of the gear shaft, resulting in easy deviation and assembly error of the gear shaft during assembly, thereby affecting the precision of gear meshing.

[0003] Due to the fact that the traditional gear shaft assembly process mainly relies on external clamps for fixation and manual adjustment, it is difficult to ensure the accurate alignment of the gear shaft teeth during the alignment of the tooth thickness, which can easily cause poor gear meshing and further cause gear wear and noise problems. In addition, the traditional scheme lacks an effective internal expansion clamping mechanism, making it difficult to simultaneously achieve gear alignment and tooth thickness adjustment, resulting in limited assembly accuracy and efficiency. At the same time, the traditional adjustment structure is usually of fixed size, making it difficult to flexibly adapt to the alignment needs of different specifications of gears. Therefore, the existing technical solutions have poor flexibility and adaptability in the assembly of multiple specifications of gears, and the assembly efficiency is difficult to meet the requirements of industrial production. Therefore, the existing problems are studied and improved, and a gear shaft tooth thickness alignment assembly is provided to solve the existing problems, aiming to solve the problems and improve the practical value through the technology.

Specific implementation

[0020] In order to make the purpose, technical scheme and advantage of the utility model more clear and obvious, below combining with specific implementation and referring to the drawings, the utility model is further detailed explanation. It is to explain that the embodiment of the utility model and the feature in the embodiment can be combined mutually in the case where there is no conflict.

[0021] It is understood that the description is only exemplary and is not intended to limit the scope of the present application.

[0022] The accompanying drawings are referred to in the description of the present application. Figures 1-4 The present application discloses a gear shaft tooth thickness alignment assembly.

[0023] The present application discloses a gear shaft tooth thickness alignment assembly, comprising: a fixed seat 100, an inner expansion tool group 200 and an alignment tooth block 300. The top surface of the fixed seat 100 is fixedly installed with a sleeve plate seat 110, and the surface of the fixed seat 100 is rotatably installed with a linkage plate 120. The top surface of the sleeve plate seat 110 is fixedly installed with a truss 130, and the truss 130 is slidably installed with the alignment tooth block 300 at one end. The top surface of the truss 130 is rotatably installed with a hand pressure handle 140, and the bottom surface of the hand pressure handle 140 is in abutment with the top end of the alignment tooth block 300. Through the rotating action of the hand pressure handle 140, the alignment tooth block 300 maintains close contact with the gear surface during the alignment process, ensuring the accuracy of the tooth thickness adjustment.

[0024] The top surface of the linkage plate 120 is rotatably connected with a threaded connecting rod 121, and the other end of the threaded connecting rod 121 is provided with a linkage rod 122 connected with the surface of the hand pressure handle 140. The length is adjusted through the threaded connection of the threaded connecting rod 121 and the linkage rod 122, so as to adapt to different specifications of the gear shaft thickness. The inner expansion tool group 200 comprises an outer expansion sleeve 220 and a core expansion rod 210 connected with the surface of the sleeve plate seat 110 and the movable sleeve ring 123 respectively. The core expansion rod 210 is slidably sleeved on the inner side of the outer expansion sleeve 220, and the surface of the core expansion rod 210 is provided with an expansion cone head 211 in abutment with the inner side of the outer expansion sleeve 220. When the core expansion rod 210 moves, the expansion cone head 211 pushes the outer expansion sleeve 220 to expand, realizing the inner expansion clamping positioning of the gear shaft.

[0025] Through the structure design, when the length of the threaded connecting rod 121 and the linkage rod 122 is adjusted, different specifications of the gear shaft can be flexibly adapted, and the accuracy of the tooth thickness alignment is ensured. Through the expansion structure of the core expansion rod 210 and the outer expansion sleeve 220, the inner expansion clamping of the gear shaft is realized, preventing the gear wear caused by assembly error.

[0026] In the present application, the expansion structure of the outer expansion sleeve 220 and the core expansion rod 210 is further optimized, so that it can adapt to more types of gear shafts. The surface of the outer expansion sleeve 220 is provided with a plurality of split gaps uniformly distributed in the circumferential direction, and the inner side of the outer expansion sleeve 220 is provided with a tapered sleeve groove matched with the expansion cone head 211, and the taper of the tapered sleeve groove is smaller than the taper of the expansion cone head 211. When the core expansion rod 210 moves along the axial direction, the expansion cone head 211 pushes the outer expansion sleeve 220 to expand radially, so as to firmly clamp the gear shaft.

[0027] In addition, the movable ring 123 is rotatably installed on the inner side of the linkage plate 120, so that the components are always kept in alignment during assembly, thereby improving the stability of gear engagement.

[0028] In the embodiment, the structure of the alignment tooth block 300 is further optimized to improve the alignment effect.

[0029] During operation, the threaded connection length between the threaded connecting rod 121 and the linkage rod 122 is adjusted, so that the alignment tooth block 300 can quickly adapt to different specifications of the gear shaft, and the clamping force and stability during assembly are ensured.

[0030] In summary, the flexible adjustment and clamping structure of the utility model realizes the alignment and accurate positioning of the gear shaft tooth thickness, thereby effectively avoiding the influence of assembly error on the performance of the gear, prolonging the service life of the gear, and improving the assembly efficiency and stability.

[0031] The working principle and use process of the utility model are as follows:

[0032] The utility model discloses a core expansion rod 210 and the inner expansion structure of outer expansion sleeve 220 realize the accurate positioning of the gear shaft tooth. When the core expansion rod 210 moves along the axial direction, the expansion cone head 211 is driven to push the outer expansion sleeve 220 to expand outward, so as to internally expand and clamp the gear shaft. Through this mode, the gear shaft is stable and does not displace during installation, thereby improving the precision of gear engagement and avoiding wear and noise problems caused by assembly error. The alignment tooth block 300 is slidably installed on the truss 130, and the contact action of the hand pressure handle 140 and the alignment tooth block 300 realizes the accurate alignment of the gear surface. When the hand pressure handle 140 is pressed downward through rotation operation, the alignment tooth block 300 is ensured to be in close contact with the gear surface, so that the alignment tooth block 300 is in contact with the gear surface, and the gear performs a certain angle deflection motion during the tooling process, and the alignment effect is completed. Through the adjustment of the hand pressure handle 140, gears of different diameters can be flexibly adapted, and the flexibility of assembly is further improved.

[0033] The threaded connecting rod 121 and the connecting rod 122 adopt a threaded connection mode, the length of the whole assembly can be finely adjusted by adjusting the rotation of the thread.
