Description

Technical Field

[0001] This invention relates to the field of automated spindle assembly technology, and particularly to an automated spindle assembly device. Background Technology

[0002] The spindle is one of the main components of a spinning machine for twisting and winding. It is an assembly with a slender rotating shaft supported at two points. Spindles are found on roving frames, spinning frames, and twisting machines. A roving spindle is a round steel rod with a groove at the top to support and drive the spindle wings to rotate. The lower end, the spindle tip, has a spindle foot oil cup for support, and the middle section uses a spindle sleeve as the upper bearing. A spinning spindle consists of a spindle rod, spindle disc, support components (commonly called the spindle), spindle hook, spindle foot, and brake. The number and rotational speed of spindles directly affect the production capacity of the corresponding process, especially for spinning spindles. The number of spindles is conventionally used to indicate the scale and production capacity of a spinning mill. The quality of the spindles is also closely related to yarn quality, power consumption, environmental noise, and labor productivity.

[0003] Traditional spindle assembly often employs separately designed tooling fixtures for step-by-step assembly, which is prone to defects due to assembly errors. Furthermore, step-by-step assembly is relatively inefficient and cannot meet the needs of modern production.

[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design an automated spindle assembly equipment to solve the above problems. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention aims to provide an automated spindle assembly device.

[0007] The turntable mechanism includes a multi-station turntable and a rotary drive assembly. The multi-station turntable has multiple floating fixture seats arranged at equal angles at its edge for positioning spindles. The rotary drive assembly is used to drive the multi-station turntable to rotate so as to move the spindles on each floating fixture seat to each station in sequence.

[0008] The spindle feeding mechanism, located at the spindle feeding station, is used to assemble the spindle into the floating jig seat;

[0010] The grease injection mechanism, located at the grease injection station, is used to inject grease into the grease injection holes on the spindle.

[0011] The residual grease cleaning mechanism, located at the residual grease cleaning station, is used to clean the residual grease from the grease injection holes on the spindle.

[0012] A steel ball assembly mechanism, located at the steel ball assembly station, is used to press steel balls into the grease injection holes on the spindle.

[0013] The steel ball assembly inspection mechanism, located at the steel ball assembly inspection station, is used to inspect whether the steel ball in the grease injection hole is installed in place;

The grease injection lifting slide is used to drive the grease injection nozzle to move up and down to insert into the grease injection hole to realize grease injection. The grease injection pump is arranged in the oil drum. The grease injection pump, the grease injection quantitative valve and the grease injection nozzle are sequentially connected through pipelines.

6. An automated spool assembly apparatus according to claim 1, wherein: The residual grease cleaning mechanism is composed of a vertical moving cylinder, a horizontal moving cylinder, a cleaning bin, a cleaning motor and a cleaning roller brush. The vertical moving cylinder is used to drive the horizontal moving cylinder to move up and down. The horizontal moving cylinder is used to drive the cleaning bin and the cleaning motor to reciprocate along the radial direction of the multi-station turntable, so that the cleaning bin is sleeved to the outer periphery of the spindle, and the cleaning roller brush and the grease injection hole are correspondingly arranged. The cleaning motor is used to drive the cleaning roller brush to brush the residual grease at the grease injection hole into the cleaning bin.

7. An automated spool assembly apparatus as claimed in claim 1, wherein: The steel ball assembling mechanism adopts a steel ball press-fitting device. The steel ball assembling and detecting mechanism is composed of a detecting telescopic cylinder, a floating latch and a displacement sensor. The detecting telescopic cylinder is used to drive the floating latch to move up and down to insert into the grease injection hole. The displacement sensor is used to detect the moving distance of the floating latch and judge whether the steel ball is installed in place.

8. An automated spool assembly apparatus according to claim 1, wherein: The spindle hook slot alignment mechanism is composed of a radial driving slide, a spindle jaw cylinder, a spindle jaw, a slot alignment cylinder and a spindle hook profiling piece. The radial driving slide is used to drive the spindle jaw cylinder and the slot alignment cylinder to reciprocate along the radial direction of the multi-station turntable. The spindle jaw cylinder is used to drive the spindle jaw to clamp two opposite side walls of the spindle. The slot alignment cylinder is used to drive the spindle hook profiling piece to move up and down to insert into the spindle hook slot on the spindle to realize alignment.

9. An automated spool assembly apparatus according to claim 1, wherein: The spindle hook pre-assembly mechanism is composed of a spindle hook vibrating disc, a spindle hook positioning assembly and a spindle hook pre-assembly assembly. The spindle hook vibrating disc is used to output the spindle hook. The spindle hook positioning assembly is used to position the spindle hook output by the spindle hook vibrating disc. The spindle hook pre-assembly assembly is used to grab the positioned spindle hook and pre-assemble it in the spindle hook slot on the spindle.

10. A spindle automated assembly apparatus as claimed in claim 1, wherein: The spindle hook locking mechanism is composed of a horizontal switching slide, a vertical assembly slide, a locking alignment cylinder, a locking alignment latch and a bolt locking device. The vertical assembly slide is used to control the locking alignment latch driven by the locking alignment cylinder to move up and down to insert into the locking hole to realize alignment, and control the bolt driven by the bolt locking device to move up and down to insert into the locking hole to realize locking. The horizontal switching slide is used to drive the vertical assembly slide to move horizontally, so that the locking alignment latch and the bolt correspond to the locking hole in sequence.
