Embodiment Construction
[0029] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .
[0030] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

The invention discloses a clamping and loosening mechanism of a double-position oil cylinder accessory head, which includes a machine tool spindle pull claw, a machine tool tooth plate, an accessory head and an oil cylinder structure. The oil cylinder structure includes an oil cylinder, a cylinder cover, a first piston, a second piston, Belleville springs, washers, limit nuts, pull rods, sealing rings and cylinder claws, the cylinder head is provided with a first oil passage, the oil outlet hole of the first oil passage is facing the first piston, and the first piston is provided with a second oil passage. The attachment head includes the main pull stud of the attachment head, the first pull stud of the attachment and the tooth plate of the attachment head. The first pull nail of the attachment and the tooth plate of the attachment head are fixed on the main pull stud of the attachment head; Positioning, the main pull nail of the accessory head is installed on the claw of the machine tool spindle, and the first pull nail of the accessory is installed on the pull claw of the oil cylinder. The tooth plate of the attachment head is released by moving the position of the claw of the oil cylinder, and the claw of the oil cylinder is opened through the second oil circuit to release the nail for the first time of the attachment, which improves the reliability of the entire machine tool and avoids the loss of the attachment head due to misoperation. fall.
Description
technical field [0001] The invention relates to the field of machinery, in particular to a clamping and releasing mechanism for a double-position oil cylinder accessory head. Background technique [0002] At present, with the rapid development of society, the processing industry has also developed rapidly, and more and more machining equipment has been applied to the production process. For processing large parts. With the use of the accessory head with indexing function, the angle of the machining tool of the gantry machining center is expanded. [0003] However, the existing clamping and loosening mechanism of the attachment head of the gantry machining center has the following defects: [0004] In the production of the existing technology, when the machine tool accessory head needs to be in the indexing state, the claw is in the open state, and the machine tool spindle pull claw tightens the main pull nail of the accessory head, but if there is an error in the clamping ...
