Abstract
The invention relates to a mechanical self-locking mechanism. A pin hole and a locating pin installation groove are arranged on a pull ring body, wherein the pin hole is used for installing a pin and a compression spring. The compression spring is installed between the pin hole and the pin to provide restoring force for the pin, the locating pin is transversely arranged in the locating pin installation groove, and the pin hole is arranged on the locating pin. A groove is arranged on the pin, one end of a cylindrical pin is instead in the groove, the other end of the cylindrical pin is matched with the pin hole on the locating pin, a press cover is connected with the pull ring body through a screw, a pin hole is arranged on the press cover, the pin hole is matched with the pin, and a locating block is connected with a box body through a screw. The mechanical self-locking mechanism is simple, reasonable and compact in structure. When a pentahedron attachment head is installed on a square ram, a relative position of the pull ring body and the attachment head box body is not fixed, and automatic steering of the pentahedron attachment head is ensured. When the pentahedron attachment head is not installed on a square ram, the positions of the pull ring body and the attachment head box body are fixed, and implement of automatic installation of the attachment head is ensured.
Description
Technical field
The present invention relates to a kind of mechanical automatic locking mechanism, specifically be specially adapted to the position that a plurality of pentahedron accessory heads are changed time restriction draw ring body automatically, belong to the frame for movement technical field.
Background technology
The automatic replacing of pentahedron accessory head is to get head unit by the hydraulic pressure that is arranged in numerical control device side's ram front end to finish with actions such as being arranged in the unclamping of blind rivet on the draw ring body, crawl.Wherein hydraulic pressure is got the position of head unit in square ram and is fixed, but draw ring body on the other side is owing to need to produce relative rotation with the accessory head casing in the action of accessory head auto-steering, so the relative position of draw ring body and casing can't be fixed, this blind rivet position that just causes being installed on the draw ring body also can't be fixed.
But when the pentahedron accessory head is placed on the accessory head support, as can not the fixed pull ring body and the relative position of accessory head casing, then when this accessory head of clamping again, hydraulic pressure is got head unit can't be in rigging position with the blind rivet that is installed on the draw ring body, this just so that the Auto-mounting of accessory head can't implement.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, a kind of mechanical automatic locking mechanism is provided, this structure can ensure the automatic replacing of a plurality of pentahedron accessory heads and the enforcement of accessory head auto-steering action.
According to technical scheme provided by the invention, a kind of mechanical automatic locking mechanism comprises pin, Compress Spring, gland, alignment pin, straight pin, locating piece, casing and draw ring body; Have pin-and-hole and alignment pin mounting groove on the described draw ring body, wherein pin-and-hole is used for mount pin and Compress Spring, and institute is that Compress Spring is installed between pin-and-hole and the pin, for pin provides restoring force; Horizontal alignment pin in the described alignment pin mounting groove, described alignment pin is provided with pin-and-hole; Have groove on the described pin, straight pin one end is installed in the groove, and the other end cooperates with pin-and-hole on the alignment pin; Gland is connected with the draw ring body by screw, and gland is provided with pin-and-hole, and described pin-and-hole cooperates with pin, can limit the position of alignment pin, makes alignment pin only can carry out front and back and slides; Locating piece is connected with casing by screw.
As a further improvement on the present invention, having cotter way on the described locating piece cooperates with alignment pin.
As a further improvement on the present invention, described Compress Spring is cylindroid helical-coil compression spring.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; In the time of on the pentahedron accessory head side of being installed in ram, make the relative position of draw ring body and accessory head casing unfixing, guarantee the auto-steering of pentahedron accessory head; And when the pentahedron accessory head was not on the side's of being installed in ram, then the position of fixed pull ring body and accessory head casing guaranteed the enforcement of accessory head Auto-mounting.

The specific embodiment
Following the present invention is further described in connection with the embodiment in the accompanying drawing:
The present invention comprises pin 1, cylindroid helical-coil compression spring 2, gland 3, alignment pin 4, straight pin 5, locating piece 6, casing 7, draw ring body 8.
The present invention adopts and has pin-and-hole and alignment pin mounting groove at draw ring body 8, and wherein pin-and-hole is used for mount pin 1 and cylindroid helical-coil compression spring 2, and cylindroid helical-coil compression spring 2 is installed between pin-and-hole and the pin 1, for pin 1 provides restoring force; Horizontal alignment pin 4 in the alignment pin mounting groove, alignment pin 4 is designed with pin-and-hole equally.Pin has groove on 1, and straight pin 5 can be installed, and straight pin 5 other ends cooperate with pin-and-hole on the alignment pin 4.Gland 3 is connected with draw ring body 8 by screw, and the pin-and-hole in the gland 3 cooperates with pin 1, and the position that can limit alignment pin 4 simultaneously makes alignment pin 4 only can carry out front and back and slides.Locating piece 6 is connected with casing 7 by screw, and the cotter way that has on the locating piece 6 can cooperate with alignment pin 4.
When on the pentahedron accessory head side of the being installed in ram, the present invention is in releasing orientation, as shown in Figure 1.Pin 1 moves downward under the effect of square ram 9, and compression cylindroid helical-coil compression spring 2, and straight pin 5 moves to the groove upper left along the groove on the pin 1, and drives alignment pin 4 to left movement, and cotter way breaks away from alignment pin 4 front ends and the locating piece 6.Under this state, draw ring body 8 can relatively rotate with casing 7, and when guaranteeing that thus the pentahedron accessory head turns to, draw ring body and accessory head casing can relatively rotate.
When the pentahedron accessory head separates with square ram, pin 1 moves upward under the effect of cylindroid helical-coil compression spring 2 restoring forces, straight pin 5 moves to the groove lower right-most portion along the groove on the pin 1, and drives alignment pin 4 and move right, and position pin 4 front ends cooperate with cotter way in the locating piece 6.Under this state, draw ring body 8 is fixed with casing 7 relative positions, guarantees thus when this accessory head is installed again, the position that the blind rivet on the draw ring body still is in accessory head when separating with square ram.
