Description

Angle head for easy positioning

The present invention relates to an angle head, and in particular to an angle head that can adjust the height of a positioning pin of the angle head.

The angle head is a machine tool accessory. When installed on the machine tool spindle, the angle head can form an angle between the center line of the machine tool and the center line of the machine tool spindle to process the workpiece, thereby increasing the processing axial direction of the machine tool.

The existing angle head is used to be assembled on a spindle, which mainly includes an angle head body and a positioning device. The spindle includes a spindle mounting slot and a positioning block. The positioning block is installed on the spindle and is located in the spindle mounting slot. On one side of the positioning block, the positioning block has a positioning groove; the angle head body mainly includes a base, a spindle transmission handle, and an adapter tool bar group. The spindle transmission handle is rotatably located on the base and installed In the spindle installation slot, it can be driven by the machine tool spindle to rotate. The adapter tool bar group is rotatably installed on the base and is connected to the spindle transmission handle with a steering linkage mechanism. The adapter tool bar group The axial direction of the group forms an angle with the axial direction of the spindle drive handle, and can be driven to rotate by the spindle drive handle. The positioning device is installed on the base and is located on one side of the base. The positioning device includes a positioning device. The positioning pin extends into the positioning groove of the positioning block to limit the connection angle between the base and the spindle and prevent the base from rotating relative to the spindle.

The relative position between the existing positioning device of the angle head and the spindle drive handle is fixed, but the size of the positioning blocks installed on different machines will be different, resulting in different positioning on different machines. The distance between the bottom surface of the block and the spindle installation groove, and the relative height between the positioning groove and the spindle installation groove will be different, and it is impossible to use the same existing angle head on different machines.

Since the relative height dimensions between the spindle mounting grooves and positioning blocks of different machines are different, different machines cannot share the same angle head. The main purpose of the present invention is to provide an angle head that is easy to adjust and position. The relative height between the positioning pin of the positioning device and the spindle drive handle can be adjusted, and can be applied to different machines.

In order to achieve the above object, the angle head of the present invention that is easy to adjust and position is used to be assembled on a spindle. The main shaft is provided with a positioning block. The angle head that is easy to adjust and position includes: an angle head body. The angle head body It includes a base; a spindle transmission handle, which is rotatably connected to the base; and a positioning collar, which is sleeved on the outer periphery of the spindle transmission handle and can be positioned relative to the base Rotate, the outer circumference of the positioning collar has a positioning slot; a positioning device, the positioning device is connected to the base and is located on one side of the base, the positioning device includes a combination block, the combination block is fixed on the The base, the combination block includes a combination sleeve hole, the combination sleeve hole extends up and down through the combination block; at least one positioning screw hole, the at least one positioning screw hole extends transversely from the outer periphery of the combination block, and is connected with the The combination sleeve holes are connected; and an adjustment hole extends up and down through the combination block; a clutch block is located above the combination block and can move up and down relative to the positioning collar. , the clutch block contains a positioning block that faces the positioning collar and selectively extends into the positioning slot of the positioning collar; a clutch sleeve hole that extends up and down through the clutch block, and Align the combination sleeve hole; an adjustment screw hole, the adjustment screw hole extends up and down through the clutch block, and align the adjustment hole; a positioning pin, the positioning pin extends into the combination sleeve hole of the combination block and the clutch The clutch sleeve hole of the block, and can move up and down relative to the combination block along the combination sleeve hole; at least one positioning bolt, the at least one positioning bolt is screwed with the at least one positioning screw hole, and selectively resists The outer periphery of the positioning pin is forced to fix the position of the positioning pin relative to the combination block; and an adjustment screw is screwed to the adjustment screw hole of the clutch block and can move up and down relative to the clutch block, The adjusting screw can move upward relative to the clutch block and resist the positioning block to adjust the relative position of the clutch block and the positioning collar.
