Disclosure of Invention
The invention aims to provide a large bar locking device of a two-plate die casting machine.
The invention has the innovation points that the four locking devices can be linked and locked only by one pushing mechanism, the operation is convenient and quick, the energy consumption is low, and the oil leakage probability is reduced.
In order to achieve the purpose, the technical scheme of the invention is as follows: a large bar locking device of a two-plate die casting machine comprises a locking sleeve and a linkage assembly for pushing the locking sleeve to rotate, wherein a locking section matched with the locking sleeve is arranged at one end of a large bar, the locking section comprises a plurality of first lugs and first grooves which are uniformly arranged at intervals in the circumferential direction of the locking section, the width of each first groove in the circumferential direction is slightly larger than that of each first lug, a plurality of arc-shaped grooves are formed in each first lug, and a plurality of annular grooves are formed by extension lines of the arc-shaped grooves and the arc-shaped grooves; the inner wall of the locking sleeve is provided with a second convex block matched with the first convex block of the locking section, and the second convex block is provided with an arc-shaped convex block matched with the arc-shaped groove; the outer diameter of the second convex block of the locking sleeve is smaller than the inner diameter of the first groove of the locking section, and a lug is arranged on the outer wall of the locking sleeve; the linkage assembly comprises three link rods and a pushing mechanism, the three link rods sequentially connect four locking sleeves through lugs, one lug is arranged on each of the head locking sleeve and the tail locking sleeve connected by the link rods, two lugs are arranged on the middle two locking sleeves, the included angle of the two lugs is 90 degrees, the included angle of each link rod is 90 degrees, and the pushing mechanism is connected with one lug and can drive the locking sleeves to rotate. When the large bar and the locking sleeve need to be separated, the pushing mechanism pushes the locking sleeve to rotate, the second convex block of the locking sleeve corresponds to the first groove of the locking section, the large bar and the locking sleeve are not contacted, and the large bar is loosened; when the large bar needs to be locked, the pushing mechanism pushes the locking sleeve to rotate, the arc-shaped convex block of the second convex block of the locking sleeve is clamped into the arc-shaped groove of the first convex block of the locking section, and the large bar is locked by the locking sleeve. The pushing mechanism pushes one locking sleeve, and other locking sleeves synchronously rotate under the action of the link rod, so that synchronous loosening and screwing can be realized.
Furthermore, four first convex blocks and four first grooves are arranged on the locking section.
Further, the pushing mechanism is an oil cylinder.
The invention has the beneficial effects that:
1. according to the invention, linkage locking of the four locking devices can be realized only by one pushing mechanism, so that the locking device is convenient and rapid, the energy consumption is low, and the oil leakage probability is reduced.
