Description

Technical Field

[0001] The invention belongs to the technical field of production of rotating shafts of crane trolley running mechanisms, and in particular relates to a fully automatic processing device for processing rotating shafts. Background Art

[0002] Crane refers to a multi-action lifting machinery that can lift and carry heavy objects vertically and horizontally within a certain range. The lifting is intermittent, that is, the corresponding mechanisms of material collection, transportation, unloading and other actions work alternately in one working cycle. The development and use of cranes in the market are becoming more and more extensive. The crane trolley is an important component of the crane, mainly used for lifting and moving materials. The trolley end beam is the supporting walking structure for the lifting device on the crane to walk on the main beam of the crane. The walking of the trolley end beam is mainly achieved through the rotating shaft and the walking wheel. The existing rotating shaft needs to be processed from a round steel blank into a finished rotating shaft through cutting, milling, drilling and milling. Each process needs to be completed by a dedicated person, and the coordination and cooperation between the processes are required to complete. The processing of the rotating shaft cannot be achieved in batches, which not only wastes a lot of time but also greatly increases the labor cost, causing a burden on the production and operation of the enterprise.

A press cylinder 20 is fixedly connected to the mounting plate 19, and the fixed end of the press cylinder 20 is fixedly connected to the mounting plate 19. The piston rod end of the press cylinder 20 passes through the mounting plate 19, and a pressure block 21 is fixedly connected to the piston rod end of the press cylinder 20.

The proximity switch 30 feeds back the received electrical signal to the industrial computer 31, and the action signal sent by the industrial computer 31 is applied to each action component, thereby completing the deep hole pre-processing operation of the trolley shaft. These basic control actions are relatively mature control actions in the prior art and are well known to technicians in this field, so they will not be described in detail here.

[0030] like Figure 3 As shown, the structure of the shaft side hole processing device is roughly the same as the structure of the shaft deep hole pre-processing device and the shaft deep hole forming processing device, and will not be described here.

[0031] When in use, the trolley shaft 33 after milling falls into the first feeding conveyor belt 2, and the first feeding conveyor belt 2 drives the trolley shaft 33 to move. When the trolley shaft 33 moves to the position of the feeding port of the placement plate 9, the proximity switch 30 on the push plate 28 detects the trolley shaft 33 and feeds back an electrical signal to the industrial computer 31. The industrial computer 31 sends an instruction to the push cylinder 27, and the piston rod end of the push cylinder 27 extends. The push plate 28 pushes the trolley shaft 33 to fall into the placement groove 10 of the placement plate 9.

The industrial computer 31 sends a command to the motor reducer integrated machine 11, the power output shaft of the motor reducer integrated machine 11 rotates, and drives the U-shaped plate 12 to move upward through the crank 15, the lifting groove 13 on the U-shaped plate 12 lifts the trolley shaft 33 upward, and under the drive of the U-shaped plate 12, it moves in the placement groove 10 of the placement plate 9 in sequence until the proximity switch 30 at the positioning cylinder 23 detects the trolley shaft 33, and feeds back the electrical signal to the industrial computer 31, the industrial computer 31 sends a command to the positioning cylinder 23, and the piston rod end of the positioning cylinder 23 extends to rotate the trolley The shaft 33 is pushed against the top plate 25, so that the trolley shaft 33 is equivalent to being close to the top plate 25 each time, which is equivalent to the same operation starting point before each processing of the trolley shaft 33, which can ensure the processing accuracy of the trolley shaft 33. The industrial computer 31 sends a command to the pressing cylinder 20, the piston rod end of the pressing cylinder 20 extends, and the arc groove 22 of the pressure block 21 presses the trolley shaft 33. At this time, the industrial computer 31 sends a command to the horizontal processing power head 24, and the horizontal processing power head 24 processes the trolley shaft 33 according to the set technical parameters. Usually, the deep hole of the trolley shaft is pre-loaded. The processing parameters of the process are adjusted between 1 / 2 and 2 / 3 of the hole depth, and the specific adjustment is based on the actual production situation on site. After the deep hole pre-processing of the trolley shaft is completed according to the processing parameters, the U-shaped plate 12 drives the trolley shaft 33 to roll down from the unloading plate 7 and fall onto the first discharging conveyor belt 3. The first discharging conveyor belt 3 drives the trolley shaft 33 to move to the discharging port, and the pushing device pushes the trolley shaft 33 into the shaft blank conveying device 1, wherein the shaft blank conveying device 1 has been described in Patent 2018111895526, and will not be described in detail here.The trolley shaft 33 is transported to the second feeding conveyor belt 4 through the lifting and conveying of the shaft blank conveying device 1. The second feeding conveyor belt 4 drives the trolley shaft 33 to move, and pushes the trolley shaft 33 into the placement groove 10 of the lifting and feeding device through the pushing device. The trolley shaft 33 is moved to the bottom of the vertical processing power head 32 through the lifting and feeding device. The vertical processing power head 32 processes the trolley shaft 33 according to the set technical parameters. After the side hole processing of the trolley shaft is completed according to the set processing parameters, the lifting and feeding device drives the trolley shaft 33 to roll off the unloading plate 7 and fall onto the second discharging conveyor belt 5. On the top, the second discharge conveyor belt 5 drives the trolley shaft 33 to move to the discharge port, and pushes the trolley shaft 33 into the placement groove 10 of the lifting and feeding device through the pushing device, and moves the trolley shaft 33 to the bottom of the horizontal processing power head 24 through the lifting and feeding device. The horizontal processing power head 24 processes the trolley shaft 33 according to the set technical parameters. Under normal circumstances, the processing parameters of the deep hole pre-processing of the trolley shaft are adjusted between 1 / 3 and 1 / 2 of the hole depth. The specific adjustment is based on the actual production situation on site, and the deep hole forming processing of the trolley shaft is completed according to the processing parameters, so that the processing of the entire trolley shaft 33 is completed. The device can realize the full-automatic processing of the trolley shaft 33, improve the production and processing efficiency of the trolley shaft 33, reduce the long production and processing time, and thus solve the problem of mass production of the trolley shaft 33.
