Machine functions

It is used for machining all kinds of hydraulic cylinders, cylinders and other cylindrical deep hole parts. It can be honed as a whole as well as partially honed; when partially honed, it can correct the taper, ellipticity and local hole diameter error of the machined parts. The rise and fall of the honing head is controlled by servo motor, which can realize the fixed-pressure feeding of the honing head as well as the quantitative feeding of the honing head.

 

Tool oil supply method: external oil injection, internal oil feed.

Workpiece clamping

The workpiece is put on two sets of V-type workpiece brackets, and the workpiece is locked with pipe clamp chain; the V-type brackets can be adjusted manually to adapt to the clamping of workpieces of different diameters.

Main structure of the machine

Main components of machine tool

Welded bed/Casted bed , honing box, 2 sets of workpiece brackets, honing bar bracket, rack and pinion, cooling system, PLC control system, electric cabinet, etc.

Control axes:

Z1 axis: longitudinal feeding movement of the grinding rod box (reciprocating movement of the tool), servo motor drives the rack and pinion mechanism through the deceleration mechanism.

Z2 axis: control the rising and shrinking of the tool, the servo motor drives the axial movement of the top bar of the rising tool through the deceleration mechanism.

Welded bed

Adopt welded bed, after two aging treatment to eliminate internal stress, stabilize the organization and size, and improve the mechanical properties.

The bed is assembled with rolling linear circular guide rail, which is used for reciprocating movement of the tool to meet the requirements of honing on high-speed movement.

Rack and pinion is assembled in the bed, which is used for tool feeding transmission, and the rack and pinion is precisely processed and heat-treated for stable transmission.

The periphery of the bed is equipped with oil catching disk.

Honing box

It is used to drive the tool rotation, and the tool speed is stepless adjustable.

The servo spindle motor drives the spindle rotation through the gear reducer, the gear is precision ground and processed, the gear tooth surface is high frequency quenching treatment, the tooth surface hardness HRC48-52, so that the gear can obtain high strength, high hardness, high wear resistance and high fatigue limit, and can withstand a relatively large alternating load, impact load.

The main shaft is supported by a combination of cylindrical roller bearings and thrust ball bearings, the main shaft has high precision and can withstand relatively large axial and radial forces.

In order to improve the life of gears and bearings, lubricating oil is used for lubrication.

Workpiece brackets

Two sets for supporting workpiece.

V-shape structure way, through the positive and negative screw control V-shape two oblique edge centering movement.

After the workpiece is placed on the bracket, the workpiece is locked manually by using the tube chain. the V-shaped beveled edges are equipped with pads with anti-skid function, which can effectively prevent the workpiece from rotating during the machining process.

Honing bar brackets

Support the honing rod during machining and measuring.

2 sets, 1 set is fixed on the bed, and the other set moves on the circular linear guideway of the bed.

Cooling System

Provides lubricant for the tool.

It mainly consists of pump, paper bag filter, magnetic roller filter and oil tank.

It can provide two oil supply methods, external oil spraying and internal oil feeding, for the tool, which can be selected and converted on the operation station.

Lubrication system

The guide slide for reciprocating movement of the grinding rod box is automatically lubricated by an automatic lubrication station with a liquid level alarm.

The gears and bearings of the grinding rod box are lubricated with lubricating oil in the box, and the lubrication is realized through the rotation of the gears.

Control system

PLC control.

Adopting human-machine interface touch screen, reciprocating speed, rotating speed, tool feeding quantity and so on can be set on the touch screen.

The operating station is assembled on the bed, and the operating panel can be manually rotated to facilitate the operation of the machine.
