Multi-station transfer flatcar

Abstract

The invention provides a multi-station transfer flatcar which is reasonable in structural design, safe, stable and reliable in operation, high in precision and low in machining cost. A platform is horizontally and rotatably mounted on a carframe; an upper rotating shaft is vertically and fixedly installed on the platform, and a lower rotating base is fixedly installed on the carframe; a chain wheel on the output shaft of a speed reducer is connected with a chain wheel on the upper rotating shaft through a chain; a drum-shaped carrier roller assembly is mounted on the carframe and is arranged in a circumferential shape; a supporting base is mounted on the carframe; a mandrel is installed on the supporting base, and a drum-shaped roller is installed on the mandrel and bears a rotary table; aflatcar positioning driving piece is mounted on the carframe; a flatcar positioning pin is mounted on the flatcar positioning driving piece; a rotary table positioning sleeve is mounted on the platform; a rotary table positioning driving piece is mounted on the carframe; a rotary table positioning pin is mounted on the rotary table positioning driving piece; proximity switches are installed on acarframe of the transfer flatcar; induction blocks are installed on all the stations; and the proximity switches are matched with the induction blocks.

Description

technical field [0001] The invention relates to a multi-station transfer flat car, which belongs to the field of factory special equipment. Background technique [0002] Transfer flat cars are widely used in manufacturing plants, mainly used in: [0003] 1. The workpiece is transferred between the previous and subsequent processes. [0004] 2. Connection between process units. [0005] 3. Workpieces are transferred between cross-spans and too many spans in the workshop. [0006] 4. Workpieces are distributed among process equipment clusters. [0007] 5. Connect multiple scattered process equipment in series through the transfer flat car, and organize production in the form of a production line, so that the production organization is orderly and the production efficiency is improved. [0008] At present, the problems existing in the transfer flat car mainly include: [0009] 1. The general-purpose flat car has a single function, which is difficult to meet the actual use ...

AI Technical Summary

Problems solved by technology

[0005] 3. Workpieces are transported between cross-spans and cross-spans in the workshop

[0009] 1. The general-purpose flat car has a single function, which is difficult to meet the actual use requirements

[0010] 2. The structure of the turntable is unreasonable, and there are many problems, especially in the transfer flat car of large workpieces:

[0011] (1) The slewing bearing is adopted, the cost of the slewing bearing itself is high and the processing accuracy of the frame and the turntable is high;

[0012] (2) The use of ring track and slewing wheel support, the processing cost is high;

[0013] (3) Adopting the rotary form of the gear ring gear, the processing cost of the large ring gear is high and the processing accuracy of the frame and the turntable is high.

[0014] (4) Adopt the form of cylindrical wheels (or bearings) arranged in the circumferential direction, and the rotation is not stable

[0015] 3. The parking accuracy of the flat car is not high
