Description

Accurate drive structure of carousel of welding burnishing machine

Technical Field

The utility model belongs to the technical field of the thermos cup burnishing machine, a accurate drive structure of carousel of welding burnishing machine is related to.

Background

The vacuum cup consists of an inner container and an outer cup, the inner container and the outer cup need to be spliced together in the processing process, then welding is carried out, then the polishing process is carried out at the welding position, wherein the polishing process comprises a plurality of procedures of rough film, fine polishing and the like, because the rotating speed of the workpiece needing to rotate is very high in the polishing process, in the welding process, the workpiece needs to rotate slowly and only needs to rotate at least one circle to complete the all-round welding, therefore, in the process, the rotating speed required by the polished process workpiece is one rotating speed, the rotating speed required by the welding process workpiece is the other rotating speed, how to combine the two processes on one equipment and change the rotating speed when the work stations are switched is a problem to be overcome, in particular, the applicant has provided a triple linkage-automatic four-station welding and polishing machine to solve this problem.

Meanwhile, the applicant gradually finds in the design that if the four-station switching is realized through the turntable, the motor used for switching the turntable to rotate by one station amplitude (1/4 circles) is usually driven by the motor connected with the bottom spindle, but the motor with large torque can continuously rotate by a small amplitude angle in the stopping process due to the inertia problem, so that the positioning effect is poor, and the accuracy is not good to control.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in figures 1 and 2, the rotary table precise driving structure of the welding and polishing machine comprises a rotary table 1, a station switching shaft 2 is fixedly arranged on the central bottom surface of the rotary table 1, a supporting seat 3 is arranged at the bottom of the station switching shaft 2 and is rotatably arranged on the supporting seat 3, four groups of workpiece clamps 4 are arranged on the rotary table 1, a workpiece spindle is fixedly connected to the bottoms of the workpiece clamps 4, the four groups of workpiece clamps 4 are positioned on four corners of a virtual square with the center of the rotary table 1 as a virtual central point, a plurality of passive deflector rods 5 are uniformly arranged at intervals on the outer circumference of the rotary table 1, a deflector motor 6 is fixedly arranged on the supporting seat, a rotary block 7 is arranged at the end part of an output shaft of the deflector motor 6, four mutually vertical or collinear active deflector rods 8 are arranged on the rotary block 7, the four active deflector rods 8 are positioned on a virtual cross, the active deflector rods 8 can be clamped between two adjacent passive deflector rods 5 and, the bottom surface of the turntable 1 is provided with four positioning blocks 9, the four positioning blocks 9 are positioned at four corners of another virtual square, one side of the positioning blocks 9, which faces the toggle motor 6, is provided with a positioning raised head 10, the toggle motor 6 is provided with a stop switch 11 capable of self-resetting, the positioning raised head 10 can be cut into the stop switch 11 from the side surface, the toggle motor 6 is internally provided with a speed reducer, and the rotating speed of an output shaft is 30-60 revolutions per minute.

The toggle motor 6 is driven to rotate 1/4 circles each time the dial motor is started, the process is completed by the driving toggle rod 8 gradually toggling the driven toggle rod 5, the process is slow, so that the process has great stability in the transposition process of the dial 1, after the positioning raised head 10 is jacked to the stop switch 11 from the side surface, the toggle motor 6 stops rotating, and because the rotating speed of the dial 1 is slow, the influence caused by inertia factors can be ignored, finally, the dial 1 stably stops at the position of 1/4 circles, and the next operation of the dial 1 stops from the position of 1/4 to the position of 2/4, and the stop effect is completed by the next positioning raised head 10.
