Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to a drilling shaft device for a roller shaft. Background Art

[0002] Belt conveyor is a continuous motion transport equipment that uses the conveyor belt as both a traction mechanism and a load-bearing mechanism. Belt conveyor has the characteristics of large conveying capacity, long conveying distance, safety and reliability, high degree of automation, simple maintenance, low operating costs, shortening transportation distance, reducing project costs, saving manpower and material resources, etc. It is widely used in mining, metallurgy, coal and other industries to transport various solid block, powdery materials or finished items.

[0003] During the operation of a belt conveyor, the roller is an essential component. Since the roller rotates during operation, frictional heat can easily damage the bearings. To maintain proper bearing function and extend the roller's life, the bearings must be lubricated. Lubricant is added to keep the bearings lubricated, reducing friction and preventing damage caused by frictional heat. By improving the existing lubrication method and adopting end-of-shaft lubrication, lubrication can be performed without stopping the machine. This requires modifying the existing roller shaft to include axial and vertical oil holes that connect to each other at both ends. The axial oil hole is a deep hole that cannot be machined using existing machining equipment, necessitating outsourcing. This not only increases manufacturing costs but also shortens product delivery cycles. While many CNC machining equipment are currently available to meet the requirements for machining deep axial holes, purchasing a separate CNC machine specifically for this purpose would significantly increase manufacturing costs.

[0004] In the machining process, general lathe is a common processing equipment in the existing technology. Therefore, in order to reduce the processing cost and realize the requirement of processing axial deep holes at both ends of the roller shaft, the existing general lathe is used to provide a drilling shaft device with simple structure and easy operation to meet the processing needs of axial deep holes. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a drilling shaft device with a simple structure and easy operation in response to the problems existing in the background technology. The drilling shaft device can be used to conveniently process axial deep holes at both ends of the roller shaft to meet the requirements of filling lubricating grease at the shaft end, thereby improving the service life of the roller. Specifically, it is a drilling shaft device for the roller shaft.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a drilling shaft device for a drum shaft, comprising a general vehicle body, a three-claw fixed drill bit and a three-claw fixed shaft, the three-claw fixed drill bit is installed on the front side of the general vehicle body, and the three-claw fixed shaft is installed on the rear side of the general vehicle body, and an axle tray is also installed on the general vehicle body, and the axle tray is located on the general vehicle body behind the three-claw fixed shaft; the three-claw fixed drill bit, three-claw fixed shaft and axle tray are arranged in a coaxial state on the general vehicle body.

[0007] Furthermore, the utility model describes a drilling shaft device for a roller shaft, wherein the general lathe body includes a workbench, a driving head and a machine tool pallet, the driving head is fixed to the front end of the workbench, and the machine tool pallet is slidably installed on the workbench and can move back and forth along the direction of the driving head, and a guide seat is also slidably installed on the top of the machine tool pallet; the three-claw fixed drill bit is installed in the driving head, and the three-claw fixed shaft is installed in the guide seat on the machine tool pallet, and the shaft tray is installed on the workbench on the rear side of the machine tool pallet.

[0008] Furthermore, the utility model describes a drill shaft device for a drum shaft, wherein the three-jaw fixed drill bit includes a drill sleeve and a three-jaw chuck, the three-jaw chuck is arranged on the drill sleeve, and the three-jaw fixed drill bit is detachably installed in the driving head through the drill sleeve.

[0009] Furthermore, the utility model describes a drilling shaft device for a drum shaft, wherein the three-claw fixed shaft includes a sleeve and a three-claw guide plate, wherein the sleeve is provided with a through hole arranged along its axial direction, and the three-claw guide plate is arranged on the sleeve facing the side of the three-claw fixed drill bit, and the three-claw fixed shaft is detachably installed in the guide seat through the sleeve.

[0010] Furthermore, the utility model describes a drilling shaft device for a roller shaft, wherein the shaft pallet includes a support column and a pallet body, the pallet body is configured to have an arc-shaped trough structure, the pallet body is fixed to the top of the support column, and the shaft pallet is detachably mounted on a workbench in the general vehicle body through the support column.

[0011] The drilling shaft device for the roller shaft described in the present invention is adopted. By installing a three-claw fixed drill bit and a three-claw fixed shaft on the main body of a conventional vehicle, the three-claw fixed shaft is used to fix the roller shaft, and the drill bit used for drilling is fixed in the three-claw fixed drill bit. The three-claw fixed drill bit is driven to rotate by the driving head, thereby realizing the drilling operation on the end of the roller shaft. At the same time, since an axle tray is also installed on the main body of the conventional vehicle, the axle tray is used to support the roller shaft to prevent shaking during drilling and improve its stability.
