the automatic turning production line for bearing outer ring is an automatic turning line integrating Electromechanical, hydraulic and pneumatic, which is manufactured by Zhejiang Dongsheng Precision Machinery Co., Ltd
purpose: rolling bearing inner and outer rings, domestic auto pin automatic line, used for inner and outer rings of pin spherical bearing
composition: the whole automatic production line can flexibly form automatic and semi-automatic production lines with different forms and lengths according to different processing process requirements of users; The machine tools are connected into a line through the conveying channel
automation: programmable controllers are used throughout the line to realize automatic operation. After the blank is loaded into the automatic silo, the system processing can be carried out automatically, and the parts in processing can be checked by 2-3 operators. The production line is also equipped with a special auxiliary machine for automatic detection, sorting and counting of processed parts
production efficiency: three shift system, monthly output of 500000-600000 sets; Cutting efficiency 2.5-3.5 seconds / set
accuracy and reliability: all purchased parts of the machine tool adopt components imported from Japan, high-quality quenching workbench, high-precision spindle components, complete box design, replaceable collet, fault alarm detection device and high-quality cutting tools to ensure the stable and reliable operation of the production line. The processed parts have high precision and small size dispersion
the rolling bearing inner ring turning line is a special equipment for turning inner and outer rings of small and medium-sized rolling bearings. The main processing objects are 628-6213 and other models. The assembly line is composed of multiple single function hosts and various auxiliary machines, which are connected through the slideway to complete the processing of each process of the inner and outer rings of the bearing. It is suitable for the mass production of the inner and outer rings of the rolling bearing. The main engine is respectively responsible for: inner hole, end face groove, inner and outer ring chamfer, inner and outer ring separation, middle groove and side groove of inner and outer ring. The auxiliary machines are composed of disc feeder, elevator (floor type and bed sticking type), scrap iron crusher, etc. The assembly line integrates Electromechanical, pneumatic and hydraulic, automatic feeding, processing and blanking, high degree of automation and short processing cycle. It can flexibly form automatic or semi-automatic assembly lines with different forms and different lengths according to different raw materials and different process requirements of users. The machining accuracy is up to 0.01mm, and the machining technology has reached the domestic advanced level. The features of its components are:
1. The main shaft
is an integral strong main shaft box. The front end of the main shaft is a paired back-to-back conical combined bearing, and the back is a two-point support with high-precision diagonal contact bearing. The bearing is lubricated with high-grade grease, so that the main shaft can maintain the best working state when rotating at high speed
2. The worktable
part of the worktable has good strength and rigidity after heat treatment and high-precision grinding, and the automatic lubricating oil supply system is adopted to maintain good matching performance of guide rail pair
3. Bed
the integral machine bed can ensure sufficient rigidity and earthquake resistance when adjusting cutting and high-precision machining. In addition, the internal mailbox is designed with a large capacity of 60 liters, which can effectively prevent the rise of oil temperature during operation
4. Workpiece clamping
simple fixture is adopted, which can automatically align the center during workpiece clamping, and the fixture is very convenient to replace
5. Electrical, hydraulic and pneumatic
all kinds of electrical, hydraulic and pneumatic components are imported parts. Long service life, low noise, stable working performance and reliable use
6. Machining accuracy
in addition to maintaining the machining accuracy of the workpiece during machining, the workpiece clamping device can also respond to abnormal conditions during clamping. If the workpiece is not clamped stably during clamping, the equipment will automatically stop processing in case of imbalance, and the design is relatively perfect
7. Main parameters
spindle motor power: 1.5-7.5kg
spindle speed: 800-200r / min
spindle radial and radial runout: less than 0.005mm
processing beat: 2.5-5s
host weight: ≈ 1200kg
Machining range: inner diameter φ 8-65mm, maximum outer diameter φ 120mm, maximum width 30mm
feed speed: longitudinal acceleration stroke 5m / s, longitudinal slow stroke 0-1m / s, transverse feed 0-3m / s
