Embodiment 1

[0019] The self-contained automatic right-angle head in the middle position of embodiment 1, as shown in the figure, includes an upper box body 11, a lower box body 12, a right-angle head main shaft 3 and a transmission shaft 2, and the upper box body 11 is provided with a plurality of pull studs 13 , the upper box 11 is connected to the oil pans of four two-stage slider oil cylinders (not shown in the figure) through a plurality of pull rivets 13, and the rear end of the right-angle head main shaft 3 to the front end of the right-angle head main shaft 3 are arranged sequentially. First gland 31, piston 32, second gland 33, pull rod 34, pull claw fixed block 35 and pull claw 36 are arranged; The handle 21 is provided with a spindle pull stud 22, the spindle pull stud 22 is connected with the machine tool spindle 5, the torque is transmitted between the tool handle 21 and the transmission shaft 2 through the cooperation of the external gear 23 and the internal gear 24, and the i...

Embodiment 2

[0020]The automatic right-angle head with its own center in embodiment 2 has basically the same structure as the automatic right-angle head in embodiment 1. The difference is that in the automatic right-angle head with its own center in embodiment 2, the horizontal through hole 411 A pin sleeve 412 is installed, and the pin sleeve 412 is sleeved on the outside of the telescopic rod 43. The telescopic rod 43 and the ejector rod 42 are made of heat-treated wear-resistant materials; Two screws (not shown in the figure), when the automatic right-angle head is in the loose state, the automatic right-angle head is placed on the head library, and the two screws press the bottom ends of the two push rods 42 respectively, so that the two push rods 42 moves upwards and drives the telescopic rod 43 to retract, and the limit key 41 is disengaged from the keyway 53, so that the automatic right-angle head is disengaged from the head storehouse, and the head loosening action is completed; an ...

Abstract

The invention discloses an automatic right-angle head with a neutral position. The automatic right-angle head comprises an upper box body, a lower box body, a right-angle head main shaft and a transmission shaft, and each of the two sides of the upper box body is equipped with a locking unit; and each locking unit comprises a limit key, an ejector rod, a telescopic rod and a spring. According to the automatic right-angle head with the neutral position, provided by the invention, the limit keys are mounted on the upper box body, the telescopic rods are mounted on the limit keys, the leftward and rightward movement of the telescopic rods is driven by the upward and downward movement of the ejector rods, and in cooperation with limit grooves and key grooves on a flange of a machine tool spindle, the neutral position function of the automatic right-angle head is realized, and the neutral position limiting problem of the right-angle head can be effectively solved; the design of puller oil cylinders can be simplified while the high rotating speed and the structural compactness of the automatic right-angle head are ensured; and an advantageous space is provided for the design of an overall machine tool.

Description

technical field [0001] The invention relates to a right-angle head of a machine tool accessory, in particular to an automatic right-angle head with a center position. Background technique [0002] The C-axis unclamping cylinder of the automatic right-angle head can be set on the right-angle head itself. This design makes the structure of the right-angle head relatively complicated; In the middle position, this type of right-angle head has a simple structure, but the height of the three-stage oil cylinder is relatively large, and it occupies more space under the ram. During the research and development of new models, the ram needs to be equipped with an electric spindle, and there is insufficient space to install a three-stage cylinder at the lower end of the ram. A two-stage slider cylinder is required, which can only realize the clamping and releasing functions of the C-axis, but not At this time, the neutral function of the automatic right-angle head has become an urgent ...
