Abstract
The utility model relates to a mechanical self-locking mechanism which is mainly characterized in that a pin hole and a locating pin mounting groove are formed in a pull ring body, wherein the pin hole is used for mounting a pin and a compression spring; the compression spring is mounted between the pin hole and the pin and provides a restoring force for the pin; a locating pin is transversely arranged in the locating pin mounting groove; a pin hole is formed in the locating pin; a trench is formed in the pin; one end of a cylindrical pin is mounted in the trench and the other end thereof is matched with the pin hole in the locating pin; a gland is connected with the pull ring body by a screw; a pin hole is formed in the gland and matched with the pin; and a locating block is connected with a box by a screw. The mechanical self-locking mechanism is simple, compact and reasonable in structure; when a pentahedral accessary head is mounted on a square ram, the relative positions of the pull ring body and the accessary head box are not fixed to ensure automatic steering of the pentahedral accessary head; and when the pentahedral accessary head is not mounted on the square ram, the positions of the pull ring body and the accessary head box are fixed to ensure automatic mounting of the accessary head.
Description
Technical field
The utility model relates to a kind of mechanical automatic locking mechanism, specifically is specially adapted to the position that a plurality of pentahedron accessory heads are changed time restriction draw ring body automatically, belongs 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 complete 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 produces relative rotation with the accessory head casing owing to needing 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 arranged 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, 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 arranged on the draw ring body, and this just makes the Auto-mounting of accessory head to implement.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of mechanical automatic locking mechanism is provided, and 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 the technical scheme that the utility model provides, 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 described draw ring body, wherein pin-and-hole is used for mount pin and Compress Spring, and described Compress Spring is arranged between pin-and-hole and pin, for pin provides restoring force; Horizontal alignment pin in described alignment pin mounting groove, described alignment pin is provided with pin-and-hole; Have groove on described pin, straight pin one end is arranged in groove, and the other end coordinates with pin-and-hole on 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 coordinates 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 further improvement of the utility model, have cotter way on described locating piece and coordinate with alignment pin.
As further improvement of the utility model, described Compress Spring is cylindroid helical-coil compression spring.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; In the time of on the pentahedron accessory head side of being arranged on ram, make the relative position of draw ring body and accessory head casing fixing, guarantee the auto-steering of pentahedron accessory head; And when the pentahedron accessory head was not on the side's of being arranged on ram, the position of fixed pull ring body and accessory head casing, guaranteed the enforcement of accessory head Auto-mounting.
Description of drawings
Fig. 1 the utility model releasing orientation schematic diagram.
Fig. 2 the utility model locking state schematic diagram.
The specific embodiment
Following the utility model is further described in connection with the embodiment in accompanying drawing:
The utility model 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 utility model adopts and have pin-and-hole and alignment pin mounting groove on 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 arranged between pin-and-hole and 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 coordinate with pin-and-hole on alignment pin 4.Gland 3 is connected with draw ring body 8 by screw, and the pin-and-hole in gland 3 coordinates 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 locating piece 6 can coordinate with alignment pin 4.
When on the pentahedron accessory head side of being arranged on ram, the utility model 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 pin 1, and drives alignment pin 4 to left movement, and in alignment pin 4 front ends and locating piece 6, cotter way breaks away from.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 pin 1, and drives alignment pin 4 and move right, and position pin 4 front ends coordinate with cotter way in 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.
