Embodiment Construction

[0028] Embodiment 1 of the constant dividing dividing head of the present invention, as Figure 1-10 As shown, there is a base 1 and a vertical indexing mechanism and a horizontal indexing mechanism fixedly arranged on the base 1 . The base 1 is provided with a connecting groove for being fixedly connected with the T-shaped groove on the workbench, which is a prior art here, and will not be repeated; the vertical indexing mechanism has an indexing shaft box 2, and the indexing shaft box 2 is relatively The first bearing and the second bearing are respectively arranged on the two box walls, and the indexing shaft box is equipped with an indexing shaft 3 through the horizontal rotation of the first and second bearings, and one end of the indexing shaft 3 has a circular connection plate 4 , the connection plate 4 is arranged outside the indexing shaft box 2, and the base 1 is provided with an auxiliary supporting device 26 on the side of the indexing shaft box 2 close to the conn...

Abstract

The invention relates to a fixed equational indexing head, which comprises a base, a spindle box and a spindle. An indexing shaft is rotatably arranged on the base; the rotating axis of the indexing shaft is vertical to the rotating axis of the spindle; an indexing gear is arranged on the indexing shaft in a check spin way; the indexing gear is provided with gear teeth and gear slots for indexing; a spindle box locking mechanism is arranged on the base and comprises a first spring bolt; the first spring bolt is provided with a locating locking head for blocking and releasing the indexing gear; the shape of the locating locking head and the shape of the gear slot or the gear tooth are complementary; and the spindle box is rotatably arranged on the base in a vertical plane through the indexing shaft. With the fixed equational indexing head, when vertical and horizontal processing are needed to respectively implement on a workpiece, the locating locking head of the first spring bolt is moved away from the position of the corresponding gear tooth or the corresponding gear slot, then the spindle box can be moved to rotate in the vertical plane, and when the spindle box is rotated to a set position, the locating locking head is blocked into the corresponding gear slot or locking the corresponding gear tooth, so that the spindle can be located, therefore, the operating process is simplified.

Description

technical field [0001] The invention relates to a machine tool accessory, in particular to a constant dividing dividing head. Background technique [0002] The dividing head is a kind of machine tool accessory used to clamp the workpiece and make the workpiece rotate and index. The dividing head is mainly used in milling machines, but it is also commonly used in drilling machines and surface grinding machines. The traditional indexing head only has a horizontal indexing mechanism for horizontal machining of the workpiece, mainly including a base, a spindle box, an indexing disk, an indexing handle and a main shaft; the indexing disk is connected to the The main shaft is connected by transmission. The main shaft can only rotate around its own axis in the horizontal plane. Usually, the main shaft needs to rotate the index disc 30-40 times for one revolution, which is extremely inefficient. The indexing accuracy is also difficult to meet the needs of some high-precision occas...
