Abstract

This invention relates to a spindle of lathe. The power end of pivot cover equipped with a connection shaft device that can engage to clutch. The clutch is controlled by rotate disc so that it can engage or depart the claw clutch. By using the structure mentioned above, power not only can drive spindle to work but let power go through pull shaft so cutter chucking system can do chuck or be loose. Using power to drive pull shaft so it is useless to use traditional oil pressure system so that it can do chuck and be loose quickly. The spindle of lathe, which can speed up while working with it, shows its improved structure.

The purpose of synchronous displacement is to effectively control the structure from the upper shaft. It can be seen that the movement of the j device into and out of the ring groove (7, (7 4) depends entirely on the rear of the oil supply dagger = end shaft (7 5 ^ y 3 2 ) Fill the hydraulic oil. Synchronize the pull rod (7 4): f the right end to drive the piston (7 5 7 4) to control the lathe to move, so as to achieve the purpose of using Ran, the above 4 is; automatic clamping of the jaws. 1. The use of hydraulic pressure supply, there are many defects in the Ministry of Taxation, such as: I oil leaks and difficult to clean up the oil and drought, easy to produce under long-term operation 丨 2. Drive by oil pressure, increase the operational Both the control and the opening and closing operation control are usually the cost of maintaining the power source I drive: main and outer: belt or other transmission components with external connection | and reduce mechanical efficiency, J use :: will cause the transmission force to be lost , 4 A also takes up a lot of space. It must be in operation, state, and clamping effect. The oil supply system will increase the oil temperature, and then the hydraulic oil will rotate in the shaft, which will quickly lose the cause. κ means force, and the temperature of hydraulic oil is prone to deterioration. To make the entire oil supply system more | up to drive: oil ί U =: clamping and positioning is entirely dependent on the hydraulic unit to control the temporary. Cheng, when the power failure or hydraulic system f early warning, early warning, Will cause the work piece to be tightened during processing. M Page 6 200410778 V. Description of the invention (3) Transformation or failure, great danger and potential [The inner edge of the invention is the practical structure of the processing machine and its shortcomings. The structure is intended to complete the power of the main input end of the present invention, which is directly linked, and achieves the exact clamping, without the lack of hydraulic supply, which can greatly reduce the speed. The present invention also combines the impact of loose coil spring crops and the impact of loose time failure. The high horsepower power of the present invention is also substantial. No additional installation is needed to avoid accidents caused by previous transmissions. Content] It is clear that people have learned the design and improvement of the design and improvement. The habit is to provide power for the drive. The main working object is additionally provided with an oil and control short spindle. In addition, it is used for the operation of the clamping of the working object and the sudden production is improved. The clamping is based on the supply of direct air, hydraulic gear or processing. It is not ideal structural composition because the material loosened and dropped. This is a source of development and research. [Axial rotation and placement of the Angular system speed, research is good, all kinds of cars are as expensive as large turning belts. , And the time is more than the design to provide the lack of bed main horsepower dynamic pull is also reliably reduced, can be years of industry and various types of professional experience, a new lathe a new type of creator. The axis, the servo lever actuation of this movement does not The overall transmission is effectively carried out by the main motor] as a supplementary source of coil springs, and it will produce a high working efficiency of the dynamic system. The turning of the spindle axis will help many inertia rates and provide a lathe spindle. With the innovative clamping and loosening mechanism of the power source, the work and control are not affected by instantaneous power failure or the hydraulic system coming loose, so it can ensure stable and safe clamping and avoid accidents. A lathe spindle is a direct transmission mechanism formed by the connection and driving of the spindle's input end. The rotary cylinder and the transmission gear or belt can effectively vibration and noise during belt transmission.

V. Description of the invention (4) Aluminum products such as aluminum alloy wheels can greatly reduce the impact of vibration on processing, so it can process fine and bright high-quality surfaces, and even use it to replace polishing and other electroplating projects. The cost is of great help. The invention also provides a lathe main shaft, which is directly connected by the power at the input end of the main shaft, eliminating the complicated and expensive hydraulic system, which can reduce energy and power loss and waste, and can also avoid the impact of high temperature hydraulic oil on the accuracy of the machine. At the same time, the daily maintenance and repair costs of the hydraulic system are eliminated, which has great practicality for users. In addition, the unique and effective clamping confirmation detection mechanism does not need to be adjusted due to the size and difference of the processed materials, which can effectively avoid the need to adjust the inspection frequently when using conventional hydraulic systems to clamp work. 丨Out of position troubles and inconveniences.
