- the operation of the collet gripping member 5 is interlocked with the operations of the pistons 311 and 321. That is, when the piston 311 or the piston 321 moves to the right in the figure, the collet gripping member 5 moves to the right and moves in the closing direction. As a result, a force acts on the collet 6 in the direction in which the collet 6 is reduced in diameter.
- the workpiece W is gripped by the collet 6 or the chuck portion 10 if grasped more widely.
- the configuration of the main shaft 1 on the left end side and the right end side in the drawing has been described, but in this embodiment, the one end force of the main shaft 1 is also applied to the other end, and the steadying pipe 71 is provided.
- the steadying pipe 71 is accommodated in the work supply path 13 in the main shaft 1.
- the leftmost end portion 71L of the steady rest pipe 71 in FIG. 2 (hereinafter simply referred to as “the leftmost end portion 71L”) is located on the portion of the main shaft 1 that extends further from the leftmost end in FIG. To position. That is, the steady rest pipe 71 protrudes from the leftmost end portion of the main shaft 1, and is attached to the sub housing 105. It penetrates the formed hole. The opening at the left end in the figure where the hole of the sub-housing 105 comes into contact with the outside is covered with a lid cover 110. Accordingly, the leftmost end portion 71L of the steady rest pipe 71 is also covered and supported by the lid cover portion 110.
- a workpiece supply port 13A formed in the lid cover 110 is connected to the hollow space of the steadying nose 71.
- a bar feeder (not shown) is provided on the left end side of the work supply port 13A in the drawing. The bar feeder supplies the bar-shaped workpiece W toward the workpiece supply port 13A.
- the steady rest Neuve 71 also serves as a guide hole for supplying the workpiece W. Since the workpiece W is supplied through the hollow hole of the steady rest pipe 71, the workpiece W can be smoothly supplied to the collet 6. In addition, since the workpiece W is supplied through the hollow hole of the steady rest knob 71, it is not necessary to provide a supply member for supplying the workpiece W in particular.
- a needle bearing 72 (needle roller bearing) is provided on the rightmost end side of the work supply path 13 in the drawing (that is, the rightmost end side of the main shaft 1).
- the needle bearing 72 is configured to include an outer ring, a cage that supports the steady rest noise 71, and needle rollers between the outer ring and the cage.
- the steady rest pipe 71 is pivotally supported by the one-dollar bearing 72.
- the rightmost end portion 71R of the steady rest pipe 71 in the drawing (hereinafter, simply referred to as “the rightmost end portion 71R”) is located in a portion where the partial force at which the one-dollar bearing 72 is located further exceeds the right side in the drawing. This position is near the workpiece gripping part that grips the collet 6 workpiece.
- the compressed air is fed into the compressed air circulation pipe 502 in the compressed air supply / discharge unit 501. Then, the compressed air passes through the compressed air circulation pipe 502 or less, the compressed air flow path 11, the compressed air connection paths 21 and 23, and the in-cylinder air flow path 33, and finally, in the drawings of the pistons 311 and 321.
- the space on the left reaches 311L and 321L.
- the pistons 311 and 321 receive pressure from the space on the left side in the figure and move to the right side in the figure. And in the figure of these pistons 311 and 321 Along with the movement to the right side, the collet gripping member 5 moves in the right direction in the figure. As a result, the collet 6 is gripped by the collet gripping member 5, and at the same time, the workpiece W is gripped by the collet 6.
- air pressure reducing valves 521 and 522 are provided in the pipe line extending from the compressed air supply device 520. By adjusting the pressure of the compressed air to be fed by these air pressure reducing valves 521 and 522, it is possible to appropriately adjust the force for clamping the collet 6 or the workpiece W.
- the operation in which the collet 6 releases the workpiece W is the reverse of that described above. That is, in the case of exerting force, the compressed air is fed into the compressed air flow pipe 503 in the compressed air supply / discharge unit 501. Then, this compressed air passes through the compressed air flow pipe 503, the compressed air flow path 12, the compressed air connection path 22, the in-cylinder air flow paths 31 and 32, and finally the piston 311 and 321 on the right side in the drawing. Spaces 311R and 321R are reached. As a result, the pistons 311 and 321 receive pressure from the space on the right side in the figure and move to the left side in the figure. As the pistons 311 and 321 move to the left side in the figure, the collet gripping member 5 moves in the left direction in the figure. As a result, collet 6 is released, and at the same time, work W is also released.
- the spindle 1 can be rotated at high speed.
- the mechanism related to the rotation of the main shaft 1 is basically composed of an element force having a cylindrical or disk shape.
- the bearing is not loaded during both clamping and unclamping, high-speed rotation is possible in either state.
- the toggle type even if the toggles are arranged at equal intervals in the circumferential direction, an unbalance of the mass arrangement is generated around the main shaft, so that it is difficult to rotate the main shaft at high speed. Even in the unclamped state, the toggle rattles, making it difficult to maintain a balance and also difficult to rotate at high speed.
- the spindle device according to the present embodiment is extremely advantageous.
- the cylinder 3 and the pistons 311 and 321 constituting the mechanism for gripping the collet 6 are present in the vicinity of the collet 6 (Fig. 2).
- the cylinder 3, pistons 311 and 321, the collet gripping member 5, the collet 6, etc. are all arranged together on the right end side in the figure of the main shaft 1.) o Therefore, the entire apparatus is reduced in size. It is possible.
- toggle type is difficult to downsize because it requires externally attached members such as an air cylinder and a lever connected to the air cylinder.
- the length of the disc spring itself is relatively large, and it is difficult to reduce the size. Compared with these, this embodiment is very advantageous.
- the spindle device of the present embodiment supports the steady-rest pipe 71-the provision of the one-dollar bearing 72 makes it possible to make the steady-state pipe 71 relatively long.
- the tip end portion (the rightmost end portion 71R in the drawing in FIG. 2) of the steadying pipe 71 can be brought closer to the portion where the collet 6 grips the workpiece W. Therefore, the occurrence of swinging of the workpiece W can be extremely effectively prevented.
- the steady rest nove 71 exists so as to cover almost the entire length of the collet gripping member 5 as shown in FIG. Therefore, the vibration of the collet gripping member 5 or the workpiece W can be reduced.
- the cylinder 3 can be made of a material having a small specific gravity, such as an aluminum alloy. In such a case, the response speed when accelerating or decelerating the spindle 1 can be further increased, and it greatly contributes to high-speed rotation.
- the cylinder 3 can also be composed of a titanium alloy. According to this, the cylinder 3 can be configured to be light and durable. Therefore, it helps to reduce the overall size of the device.
- the compressed air flow paths 11 and 12 are formed in the spindle 1, and the compressed air supply, A discharge unit 501 is provided, and the rotary joint and the main shaft 1 are integrated. Therefore, a so-called air tube which has been conventionally used is no longer necessary, and accordingly, the apparatus configuration can be simplified and the cost can be reduced.
- the compressed air is a power source for the pistons 311 and 321, but generally a pressurized fluid may be used.
- pistons 311 and 321 are hydraulically driven.
- the pressure of the pressurized fluid can be set to an appropriate value, one piston may be used! /.
- the steadying pipe 71 is supported at one end of the main shaft 1.
- a one-dollar bearing 72 was used as the supporting part.
- the present invention is not limited to this.
- a ball bearing can be used as a support portion that supports the steady-rest pipe 71 at one end of the main shaft 1.
- a sliding bearing can be used as a support portion that supports the steady rest pipe 71 at one end of the main shaft 1.
- the present invention can be used for a spindle device for rotating a workpiece at high speed. Further, the present invention can be used for a spindle device for reducing the size of the entire apparatus.
