Description

Technical Field

[0001] The utility model belongs to the technical field of turntables, and in particular relates to a turntable merge ring with a fixed structure. Background Art

[0002] The slip ring is mainly used in radar servo systems to rotate 360° and continuously transmit power and data signals. At present, the fixed structure of the slip ring mainly adopts the connection and fixation of the rotating ring and the rotating shaft, and the fixed ring and the fixed base are connected and fixed through the transition connection of parts. The disadvantage is that the coaxiality of the rotating ring and the fixed ring is guaranteed by controlling the structural dimension tolerance and assembly cumulative error of the fixed parts connected to the fixed base, which is very easy to cause the slip ring to be connected by force, resulting in a decrease in the performance and life of the slip ring. Utility Model Content

[0003] In view of the problems existing in the prior art, the utility model provides a turntable slip ring with a fixed structure. The fixed structure simplifies the installation steps of the slip ring, reduces the accumulation of assembly errors, and ensures the non-stress connection of the slip ring.

[0004] The utility model adopts the following technical solutions:

[0005] A turntable merge ring with a fixed structure comprises a mounting plate, a fixing plate, a merge ring body, a bracket, a rotating shaft, an elastic pin, a slewing bearing and a base.

[0006] The matching hole of the bracket is at the center position, the rotating shaft and the bracket are interference fit and fixed with elastic pins, the rotating shaft is fixed to the base through the bracket, the slip ring body is fixed to the fixed plate, the fixed plate is fixed to the mounting plate, the rotating ring and the rotating shaft are fixed by set screws, the base is connected and fixed to the outer ring of the slewing bearing, and the fixed plate is connected and fixed to the inner ring of the slewing bearing through the mounting plate. The fixing ring installation datum of the slip ring body is designed on the inner ring of the slewing bearing, and the rotating ring installation datum of the slip ring body is designed on the outer ring of the slewing bearing, and the assembly accuracy of the slip ring is guaranteed by ensuring the processing accuracy of the slewing bearing.

[0007] As a preferred solution: the rotating shaft and the bracket are connected by interference fit and fastened by elastic pins.

[0008] The beneficial effects of the utility model are:

[0009] A turntable merge ring with a fixed structure, the rotating shaft and the bracket are interference fit, fixed by elastic pins, and because there is a positioning step between the bracket and the base, the bracket and the base can be directly positioned and fixed, so that the rotating shaft 5 is at the center of the base, and the merge ring can be directly inserted into the rotating shaft and connected and tightened. The fixed structure has low requirements on the structural dimension tolerance of the connecting and fixing parts, simplifies the assembly steps of the merge ring, has a simple structure, improves assembly accuracy and efficiency, and ensures the performance and life of the merge ring.

[0012] Figure markings: 1-mounting plate, 2-fixed plate, 3-collecting ring body, 301-fixed ring, 302-rotating ring, 4-bracket, 5-rotating shaft, 6-elastic pin, 7-slewing bearing, 701-slewing bearing inner ring, 702-slewing bearing outer ring, 8-base. DETAILED DESCRIPTION

[0013] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0014] like Figure 1 As shown, the outer ring 702 of the slewing bearing is fixed by the upper positioning step of the base 8, the mounting plate 1 is fixed to the inner ring 701 of the slewing bearing by the positioning step, the matching hole connecting the bracket 4 and the rotating shaft 5 is ensured to be in the center position by the dimensional tolerance, the rotating shaft 5 and the bracket 4 are interference fit and fixed by inserting the elastic pin 6, the bracket 4 and the base 8 are fixed by threaded fastening connection, and the rotating shaft 5 is measured and corrected by the dial indicator to ensure that the coaxiality of its axis and the rotation axis of the slewing bearing 7 is within 0.2mm. The corresponding mounting holes and mounting surfaces on the inner ring 701 of the slewing bearing are based on the rotation axis of the slewing bearing 7, and the position tolerance of the mounting holes and the verticality tolerance of the mounting surfaces are designed.

[0015] like Figure 2 As shown, the rotating shaft 5 and the rotating ring 302 are fixed by means of set screws, and the fixing plate 2 and the mounting plate 1 are fixed by means of threaded fastening connection.

[0016] like Figure 1As shown, compared with the conventional method of connecting and fixing the rotating ring 302 and the base 8 through transition parts, which cannot ensure the positioning accuracy and requires manual calibration, the structure of the utility model is simple, and the slip ring body 3 can be directly inserted into the rotating shaft 5 to position it at the center position, simplifying the installation steps, unifying the installation reference of the fixed ring 301 and the rotating ring 302 on the slewing bearing 7, and reducing the accumulation of assembly errors. It only needs to ensure the processing accuracy of the slewing bearing 7 to improve the assembly accuracy of the slip ring body 3 and ensure the performance and life of the slip ring.
