Description

Technical Field

[0001] The utility model relates to the technical field of pin processing equipment, in particular to a pin processing equipment for construction machinery. Background Art

[0002] In the pin cutting process, waste chips generated by cutting are inevitable. The traditional method is to directly collect these waste chips into the collection tray equipped on the lathe and uniformly process them after the processing is completed. However, currently, a water spraying cooling device is equipped in pin cutting. Although it effectively reduces the tool temperature and assists in waste chip removal, it also introduces new problems: water accumulates in the collection tray, which not only increases the handling difficulty but also poses a potential risk of bearing pressure on the structure of the collection tray, threatening its durability. For this reason, we propose a pin processing equipment for construction machinery. Summary of the Utility Model

[0025] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Referring to the attached Figure 1-7 , a processing device for a construction machinery pin shaft, comprising a lathe 1 and a water spray nozzle 2 arranged above the cutting position. During the cutting process of the pin shaft, the water spray nozzle 2 sprays water to cool the cutting and wash away the chips. A collection tray 4 is arranged below the cutting position of the lathe 1. The bottom of the collection tray 4 does not contact the ground. A plurality of convex columns 5 extending upward are arranged on its bottom plate. The top of the convex column 5 is lower than the outer edge of the collection tray 4, and a drainage channel penetrating the bottom of the collection tray 4 is opened therein. The upward extension of the convex column 5 can prevent the chips from being washed out while draining water. The water sprayed from the water spray nozzle 2 falls into the collection tray 4. When the water volume exceeds the top of the convex column 5, it will be discharged through the drainage channel, avoiding excessive water volume in the collection tray 4, which is inconvenient for handling and may cause damage to the bottom of the collection tray 4 due to excessive pressure.

[0027] In this embodiment, a chip-proof cap 61 covering the top of the drainage channel is arranged on the convex column 5. The diameter of the chip-proof cap 61 is larger than the inner diameter of the drainage channel, which can prevent chips from falling into the drainage channel during the cutting process of the pin shaft. A positioning column 62 extending to the inside of the drainage channel is arranged at the bottom of the chip-proof cap 61, and the diameter of the positioning column 62 is smaller than that of the drainage channel. The chip-proof cap 61 is made of plastic material. When the water volume in the collection tray 4 exceeds the top of the convex column 5, the chip-proof cap 61 floats upward, and the water in the collection tray 4 is discharged to the outside of the collection tray 4 through the drainage channel.

[0028] In this embodiment, a screw rod 71 is internally threaded at the bottom of the positioning column 62. A knob 72 with a width larger than the diameter of the drainage channel is arranged at the bottom of the screw rod 71. By the limit of the knob 72, the positioning column 62 can be prevented from moving out of the drainage channel, that is, the chip-proof cap 61 can be prevented from floating away. Rotating the knob 72, at this time, the screw rod 71 rotates inside the positioning column 62, further enabling the knob 72 to move in the vertical direction of the positioning column 62 following the screw rod 71. At this time, the distance between the top of the knob 72 and the bottom of the collection tray 4 changes, facilitating the control of the floating distance of the chip-proof cap 61, that is, the discharge speed of the water in the collection tray 4 through the drainage channel can be controlled.

[0029] In this embodiment, a protective cylinder 63 is provided at the bottom of the chip guard 61. The outer wall of the protective cylinder 63 is fitted with the inner wall of the drainage channel. A number of drainage holes 64 are circumferentially formed in the outer wall of the protective cylinder 63. The floating cutting debris can be filtered through the drainage holes 64. There are a number of drainage holes 64 on the vertical surface of the protective cylinder 63, which will not affect the drainage speed of the drainage channel.

[0030] In this embodiment, a slideway 3 for the collection tray 4 to slide is provided on the lathe 1. The collection tray 4 is pulled out from the slideway 3 to facilitate the cleaning of the debris in the collection tray 4. The height of the bottom of the collection tray 4 from the ground is greater than 10 cm to prevent the bottom of the collection tray 4 from contacting the ground and affecting the drainage of the drainage channel.

[0031] In this embodiment, the chip guard 61 is semi-circular, conical or tapered. The debris falling on the chip guard 61 will fall into the collection tray 4 after being washed by water and will not fall into the drainage channel, thus preventing the drainage channel from being blocked.
