Problems solved by technology

[0003] In order to realize the rotation of each turntable and the synchronous rotation between the turntables, the multi-station turntable in the prior art adopts a transmission structure based on a sun gear-planetary gear. This transmission mechanism is not only heavy and bulky, but also has low matching accuracy. , The backlash is large, and it is necessary to specially design and manufacture various non-standard torque transmission components such as gears; at the same time, the mutual restraint or cooperation between the sun gear and the planetary gear also puts forward higher requirements for the assembly and debugging accuracy of the transmission mechanism. It is not easy to meet the design accuracy index; such a structure cannot use lubricating materials under vacuum conditions, which makes the components of the transmission structure easy to wear, and the maintenance and replacement costs are high and the operation is troublesome

Embodiment 1

[0033] like Figure 1 to Figure 3 As shown, a multi-station vacuum welding table includes a turntable 11 and a plurality of chucks 12 installed on the turntable 11, and also includes a first driving part for driving the turntable 11 to rotate around the axis of the turntable 11 itself, and also includes a The second driving part that drives each chuck 12 to rotate around the axis of each chuck 12 itself, the second driving part includes a number of rotation shafts 21 equal to the number of chucks 12, and each chuck 12 passes through a rotation shaft 21 And at least one third bearing 20 is connected with the turntable 11, the second driving part also includes a driven gear 22, the number of the driven gear 22 is equal to the number of the chuck 12, and a slave gear is installed on each rotating shaft 21 Driven gear 22, described second driving part also comprises second motor and toothed belt 23;

[0034] Each driven gear 22 is tooth-connected with the toothed belt 23, and the...

Embodiment 2

[0040] like Figure 1 to Figure 3 As shown, this embodiment is further limited on the technical solution provided by embodiment 1. As an integrated solution, it also includes a bracket 1 on which a motor mounting frame 7 is arranged, and the turntable 11 is also connected to There is a disk shaft, and the disk shaft is installed on the bracket 1 through the second bearing 10, and the first driving part includes a first motor connected with the disk shaft. The above disk shaft is the rotating shaft of the turntable 11, and the first motor is used to drive the rotation of the disk shaft to realize the position adjustment of the chuck 12 on the turntable 11 in space. Preferably, the disc shaft is set to be coaxial with the axis of the first motor. Preferably, for the convenience of controlling the accuracy of the stop position of the chuck 12, the first motor is directly driven by a torque motor or a servo motor. Simultaneously, in order to optimize the stress of this welding st...

Abstract

The invention discloses a multi-station vacuum welding table. The multi-station vacuum welding table comprises a turntable and a plurality of chucks installed on the turntable, and further comprises afirst driving part used for driving the turntable to rotate around the axis of the turntable and a second driving part used for driving the chucks to rotate around the axes of the chucks. The seconddriving part comprises self-rotating shafts with the number equal to that of the chucks, and each chuck is connected with the turntable through one self-rotating shaft and at least one third bearing.The second driving part further comprises driven gears, the number of the driven gears is equal to that of the chucks, and each self-rotating shaft is provided with one driven gear. The second drivingpart also comprises a second motor and a toothed belt, the driven gears are in toothed connection with the toothed belt, and the second motor is used for driving the toothed belt to rotate. Because of the structural design, the multi-station vacuum welding table can not only improve the welding efficiency, but also is suitable for working conditions without lubricating materials.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a multi-station vacuum welding platform. Background technique [0002] At present, in the field of special welding, such as electron beam, laser, and plasma welding, the welding turntables configured by the corresponding welding equipment are usually single-station, and there are also a small number of multi-station turntables. The above multi-station turntables can effectively improve welding efficiency. [0003] In order to realize the rotation of each turntable and the synchronous rotation between the turntables, the multi-station turntable in the prior art adopts a transmission structure based on a sun gear-planetary gear. This transmission mechanism is not only heavy and bulky, but also has low matching accuracy. , The backlash is large, and it is necessary to specially design and manufacture various non-standard torque transmission components such as gears; at the...
