Description

Technical Field

[0001] The invention belongs to the technical field of gear transmission assembly and adjustment, and particularly relates to an automatic assembly and adjustment device and method for an antenna base reducer. Background Art

[0002] The radar azimuth transmission system consists of a motor, a reducer, a gear pair and other structural components. The contact quality of the gear pair meshing contact area directly affects the transmission smoothness and also has a great impact on the gear life and transmission noise.

[0003] At present, the meshing and adjustment method between the reducer and the azimuth gear pair is to use a crane to manually align and adjust the reducer. The posture of the reducer and the pinion is difficult to accurately control and fix. The side clearance index is used instead of the center distance, and the meshing spot is used to estimate the parallelism of the gear pair axis. The meshing quality is adjusted by adding a copper pad to the reducer.

[0004] The existing assembly and adjustment process requires repeated disassembly and assembly of the reducer's fastening bolts and repeated measurement of the gear pair side clearance and meshing spots. Through research, it is found that there is currently no dedicated equipment in the industry for gear pair meshing detection and adjustment. It requires high operator experience, is complex to operate, and has low efficiency. It is difficult to achieve precise control of the gear pair meshing assembly and adjustment, which is not conducive to quality control of the assembly process.

[0005] Therefore, it is of great significance to solve the problems of complex operation, low efficiency and difficulty in precise control in the assembly and adjustment of the reducer of the existing antenna base transmission system. Summary of the Invention

The adjustable support seat 3 includes: a second mounting base 30, a second drive motor 31, a second sliding guide rail 32, a second ball screw transmission module 33, a support column mounting base 34, a support column 35, and a claw 36; the support column 35 is installed on the support column mounting base 34, and the claw 36 is installed on the support column 35, which is used to position and fix the base of the antenna base; the second drive motor 31 can drive the support column mounting base 34 to move along the second sliding guide rail 32 through the second ball screw transmission module 33, and adapt to bases of different sizes through the movement of the support column 35 and the claw 36.

[0021] Step 2: Hoist the antenna base 13 onto the adjustable support base 3, place it stably, and firmly clamp the base with three claws 36 to achieve positioning of the base 13;

[0022] Step 3: Place the combination of the reducer 10 and the pinion 11 on the dynamic platform 42 of the six-degree-of-freedom platform assembly 4, use the positioning block 49 and fasteners to position and fasten the reducer 10, and use the alignment translation stage 2 to roughly adjust the position of the reducer until the gap between the pinion and the gear is within 50 mm;

[0031] Step 9: Install the reducer and pad in place to complete the entire assembly and adjustment process, and achieve high-precision meshing assembly of the reducer gear pair.

[0032] The beneficial effects of the present invention are:

[0033] Compared with the prior art, the present invention has the following technical effects:

[0034] 1) The current method for meshing and adjusting the reducer and the azimuth gear pair is to use a crane to manually align and adjust the position. The posture of the reducer and the pinion is difficult to accurately control and fix. The present invention uses a six-degree-of-freedom parallel mechanism to support and adjust the position of the reducer, which can achieve precise control and fixation of the reducer, and realize rapid installation and adjustment of the reducer and gear pair, thereby improving the level of automation.

[0035] 2) The existing technology uses the side clearance index to replace the center distance and the meshing spot to estimate the parallelism of the gear pair axis, which has a large error. The present invention uses an alignment detection module and an image level to directly measure the center distance and axis parallelism of the gear pair, and uses a six-degree-of-freedom parallel machine for adjustment, achieving a gear axis parallelism adjustment accuracy of 1 second and a center distance adjustment accuracy of 0.01mm, greatly improving the assembly accuracy.

[0036] 3) The existing technology adjusts the meshing contact quality by padding copper sheets between the reducer and the base, which relies heavily on the operator's experience and requires multiple disassembly and measurement, resulting in low efficiency. The present invention adjusts the reducer into place and directly measures the clearance data between the reducer and the base. The thickness value of the pad is obtained based on the measured data. After one-time processing and reassembly, the reducer gear pair can be assembled, thereby improving assembly and adjustment efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
