Abstract

The present invention relates to a structure of a main shaft of a center cutting machine; the main shaft is equipped with a clutch, which can disengageably engage the coupling of the power source, and which is formed with sloping trenches, so that the power source can be switched between a first position, under which the main shaft is powered by the power source, and a second position, under which a pulling rod is powered by the power source for the operation of the chunk to clamp and unclamp the knife. Therefore, the pulling rod can be powered to move by the power source directly without need for additional oil cylinders.

Description

200413128 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a spindle structure of a center cutting machine, and in particular refers to a type driven by a power source of the spindle without the need for hydraulic connection. The clutch and its related components can be directly used to clamp or release the required tool, and thereby achieve a center cutting that greatly reduces the number of powerful coil spring assemblies and has more reliable and clear operating characteristics. Machine-specific spindle structure was first created and applied. [Prior art] As shown in Figures 14 and 15, it is the main shaft structure of a central cutting machine. The main shaft structure (8) is provided with a main shaft shaft seat (8 1) and a shaft sleeve (8 2) to provide a main shaft sleeve ( 8 3); the oil circuit (8 4 1), (8 4 2) of the oil pressure device (8 4) set in the inner hole (8 1 1) of the main shaft seat (8 1), so that it can drive the piston (8 4 3) Act. The middle hole (844) of the piston (8 4 3) is connected to the convex ring (851) of the pull rod (85) to be displaced with the movement; and a coupling (86) and power are used at the top of the main shaft seat (8 1). The output shaft (871) of the power source (87) is fixedly connected, and the through hole (8 7 2) of the output shaft (87) can be connected to the rotary joint (88) at the other end of the power source (87) to provide the required cooling water. It is sent out from the pull rod (8 5) for cooling during cutting. It can be known from the above structure that the operation of the draw rod (85) depends entirely on the driving of the oil pressure device (84) to control the loosening or clamping of the tool shaft sleeve (89); and the oil pressure device (84) is deep Hidden in the inner hole (811) of the main shaft seat (8 1), the oil passages (841), (8 4 2) entering and exiting are difficult to design, process and install, and troubleshooting and maintenance are more difficult.

V. Description of the invention (2) It is not easy, and it has a significant impact on the processing efficiency and process of the production line. Tian J's Furthermore, the oil pressure device must be equipped with a more expensive oil pressure unit and control equipment, and there will be quite annoying problems of oil leakage and greasy dirt, and the maintenance cost of normal operation is also high. In addition, the oil supply from the hydraulic unit will cause inoperative operation when the power failure or hydraulic system failure occurs. ^ $ Λ Α At > Φ. 'In addition, the shaft (9), the tie rod (9 1 and the top end are pivotally connected or the elasticity and shape displacement required for the knife are released, so the coil spring is shown in the figure. It will be applied when the lever shaft is turned. Please refer to the push source that can be connected outside to drive the shaft. The clamping force of the shaft sleeve is small, no 9 2). The stack (91) produces noise. The sixteenth figure is enough to set a lot of strong rods (9 3) to move the tie rods (operation. Use, but each piece of method should deal with the tie rods stacked on top of each other with the number of phases half the length of the phase will also affect the weight, for And the disc that provides the force to push 9 1) above the coil spring ((91 digits more than the number of 'to cause the heart balance another suitable spring (9 rods (9 for up and down 9 2) 9 2)) The amount is the unfavorable clamping force in the 'accumulation set up', 2), and then 3) the other end is lifted for clamping Can be reached by the displacement of the force necessary line, the length will be few, and with the high-speed machine
