[Problems to be solved by the device]

A conventional chuck that rotates the handle of the scroll chuck by the rotating means of the motor. With a jack, the chuck must always remain in place, which is why the chuck The chuck is equipped with a motor-equipped handle and a fixed-position fixing means. It was necessary to prepare it in the vicinity of. Therefore, the purpose of this invention is to integrate the chuck device and the motor device into one unit. By making it a compact automatic scroll chuck, and a small diameter To be able to grasp a wide range from to relatively large diameter workpieces, and Provided is an automatic scroll chuck whose gripping force can be easily adjusted.

[0005]

[Means for Solving the Problems]

In order to solve the above problems, the automatic scroll chuck of this invention is Plural sliding claws arranged at equal intervals and mounted so as to be slidable in the radial direction. The material and the groove that holds and guides this sliding claw member are In addition, a spiral scroll groove that meshes with the lower concave and convex portion of this sliding claw member is formed. Integrated scroll chuck, integrated type adjacent to the scroll chuck body It is equipped with a built-in motor, and the tip of the cylinder operated by the drive of this motor. The clutch claw and pinion gear claw are linked to the movement of the sliding lever fixed to the end. Are formed so that they can mesh with each other, and the clutch claw and the pinion gear claw mesh with each other. The rotating shaft of the motor is adapted to rotate the scroll board.

[0006] Furthermore, they are arranged at equal intervals around the axis and mounted so as to be slidable in the radial direction. A plurality of sliding claw members and a groove for holding and guiding the sliding claw members are provided on the scroll board. Of the spiral claw that meshes with the lower concave-convex part of this sliding claw member. The scroll claws are formed, and the sliding claw members move the workpiece by rotating the scroll board. In a scroll chuck that can be gripped, the scroll chuck body The motor that is integrally provided at the position adjacent to and the tip of the rotation shaft of this motor The provided pinion gear and the pinion gear tool integrally formed with the pinion gear. And the cylinder lever that operates in association with the drive of the motor is the motor. And a clutch slidably provided on the rotary shaft of the cylinder. The scroll disk meshed with the pinion gear was rotated by pushing the lever.

[0007] Also, the clutch claw and pinion gear claw phase should be set so that the workpiece is not gripped excessively. The interlocking portions were formed in a trapezoidal shape.

[0008] Further, the meshing portion between the clutch claw and the pinion gear claw is formed in a trapezoidal shape. In addition, when the clutch claws and the pinion gear claws are engaged with each other, Make sure that a gap is formed between the claw and pinion gear claw and the meshing recess. did.

[0008]

[Embodiment of device]

[Example 1] This invention will be described below with reference to the embodiments shown in the drawings. A plurality of claws capable of holding a workpiece in a holding groove 2 on one side surface of the scroll chuck body 1. Mount part 3. Concavo-convex portion 4 and scroll plate 5 are formed below the claw portion 3. Since the concave spiral groove 6 is engaged with the scroll disk 5, In both cases, the claw portion 3 slides in the gripping direction or in the non-gripping direction.

[0009] When the motor 7 integrally formed adjacent to the scroll chuck body 1 is driven, The sillingu 10 is guided by a guide rod 11 and has a lever 12 fixed at its tip. With the tip of the clutch 8 fitted in the groove 9 formed in the clutch 8, the clutch 8 is It is moved toward the ON gear 13. Clutch on one side (pinion side) of clutch 8 The claw 14 is formed, and the pinion gear is also provided on the clutch side of the pinion 15. Since the clutch 16 is formed, the clutch 8 moves in the direction of the pinion gear 13 The rotation of the rotary shaft 17 of the meshing motor 7 causes the pinion 13 to rotate.

[0010] When the clutch claw 14 and the pinion gear claw 16 mesh with each other, the pinion gear 13 becomes It rotates, but before the clutch claw 14 and the pinion gear claw 16 mesh, The rotating shaft 17 of the motor 7 idles with respect to the ON gear 13.

[0011] The outer circumference of the scroll disk 5 is a scroll disk that can mesh with the pinion gear 13. A gear 18 is formed. Therefore, as described above, the clutch claw 14 and the pinion are When the gear claws 16 mesh with each other, the rotation of the pinion gears 13 causes the scroll disc 5 to rotate. Will rotate. Therefore, the rotation of the rotary shaft 17 of the motor 7 remains unchanged. The pinion is rotated via the latch 8, and the scroll board 5 is further rotated. As described above, the rotation of the scroll board 5 causes the plurality of claw portions 3 that can hold the workpiece to move. Concave spiral formed on the surface of the scroll board and the concave-convex portion 4 formed at the bottom of the claw. The claw 6 meshes with the groove 6 and the claw slides in the gripping direction to grip the workpiece A.

[0012] When the pressing force of the cylinder is deleted, the clutch claw 14 and the pinion gear claw 16 are Is disengaged and the rotary drive of the rotary shaft 17 of the motor 7 is no longer a scroll disc. No longer transmitted to 5.

[0013]

Example 2 Clutch claw 14 and pinion gear claw 16 that can mesh with each other, and The clutch recess 23 and the pinion adjacent to both sides of the claw 14 and the pinion gear claw 16 The gear claw recess 24 has a trapezoidal shape with inclined sides on both sides of the meshing portion. The clutch claw 14 and the pinion gear claw 16 are engaged with each other. In the state, each of the pinion gear claw concave portion 24 and the clutch concave portion 23 is Since it is formed larger than the clutch claw 14 and the pinion gear claw 16, the meshing The void portion 22 is formed in the open portion. In FIG. 9, the cylinder 1 The lever 12 attached to 0 pushes the clutch 8 against the pinion gear 13. However, if excessive force is applied to the claw portion 3, the clutch claw 14 and the pinion gear claw 16 The gripping force of the claw portion 3 can be adjusted by the disengagement of the It is designed so that it can be protected.

[0014] When releasing the gripping force, the clutch claw 14 and the pinion gear claw 16 are engaged. Since the gap 22 in the mating portion is unloaded, the clutch claw 14 becomes the pinion gear claw 1. It moves smoothly until it hits 6, and the clutch claw 14 hits the pinion gear claw 16. When sagging, a strong force is generated by the hammer effect, so it is easy to release the gripping force.
