The line boring machine is mainly one kind of on-site portable equipment ,developed for the on-site maintenance of construction machinery. It is mainly used for the boring and welding repair of small and medium-sized  shaft pin holes. It is a necessary portable line boring and welding equipment in the construction machinery maintenance industry. Used for boring and welding holes on excavators, loaders, cranes, crawler cranes and large marine cranes.

Application range:

line boring and welding of shaft pin holes, revolving holes, main arm connecting holes, and ring holes on various construction machinery. The welding and boring of concentric holes and multiple rows of holes in construction machinery such as presses, loaders, cranes, and one-time positioning and installation can ensure the concentricity of multiple holes.

Line boring machines are mainly used for portable machine boring. It has accurate line boring quality, easy to carry, small footprint, and high precision; it mainly borings oil cylinders, hydraulic cylinders, and cylinders on the car, and can also be used for other machine tools. The machine tool can not only welding and boring, but also can perform limit end face processing. When boring, use the internal chip removal method or the external chip removal method. The machine tool itself has strong rigidity, good precision connectivity, wide range of spindle speed, and the drive system is driven by an exchange servo motor, which can adapt to the needs of many deep hole processing techniques. Hydraulic devices can be used to tighten the oil applicator and tighten the workpiece. , Intact display instrument, it is completely trustworthy.

A new type of line boring machine developed in accordance with market demand. The whole machine adopts a hollow cast steel frame and is light in weight. It adopts an aluminum shell pure copper wire-wrapped motor. The main rotation and feed are respectively driven by pure mechanical transmission. Both manual and automatic integration can be realized. , High and low speed change is set according to fine line boring and rough line boring. Superior performance and good stability. The design is completely based on on-site maintenance, and the on-site processing operation can be completed by one person, which greatly improves the efficiency. The weight of the host is about 27KG, which is convenient and light. It is your right-hand man on site. Since the product was promoted to the market, it has been well received by users at home and abroad, creating powerful value for customers. Similar products have superior performance and high cost performance. welcome all friends visit our portable line boring and welding machine.

The line boring welding machine mechanism is arranged at one end of the boring bar; a positioning plate is installed on the boring bar, and is characterized in that: the tool moving mechanism includes a support seat connected to the reducer housing, and the upper edge of the support seat is along the line boring bar. A support frame is provided in the axial direction, a symmetrical installation guide shaft is installed on the support frame, a sliding seat is installed on the guide shaft, a synchronization frame is fixedly installed on the side of the sliding seat close to the boring bar, and the other end of the synchronization frame Connecting the outer sleeve, the outer sleeve is sleeved on the rotary sleeve, and the rotary sleeve is fixedly installed on the line boring bar by fasteners;

The cutting mechanism further includes a transmission screw, which is installed on the support frame parallel to the guide shaft, one end of the transmission screw is installed with a hand wheel; the other end of the transmission screw is installed near the front Gear, the front large gear meshes with the second small gear, the second small gear is coaxially installed with a third large gear, and the third large gear meshes with a traveling gear; the traveling gear is installed on the boring bar; The third large gear and the second small gear are also coaxially installed with a switching handle, the lower end of the switching handle is provided with a coupling plate, the coupling plate is sleeved on the line boring bar through a rotary sleeve, and the switching handle is provided with a positioning The positioning plate is provided with a positioning pin hole, a positioning pin is provided corresponding to the position where the front large gear meshes with the second small gear, and a protective cover is also provided on the knife-moving mechanism.
