The specific implementation scheme of the utility model is as follows:

[0030] The quick locking device of a quenching press comprises a frame 1, a plurality of locking holes 2 are provided on the frame 1, an inclined surface A3 is arranged on the frame 1 around the locking holes 2 in a fixed structure manner, a quenching water spray device 7 is connected to the frame 1, a rotary lock rod 4 is arranged on the quenching water spray device 7 in a rotating structure manner, one end of the rotary lock rod 4 passes through the locking hole 2, a locking head 5 adapted to the locking hole 2, the locking head 5 is arranged on one end of the rotary lock rod 4 in a fixed structure manner, an inclined surface B6 rotatably fitted with the inclined surface A3 is arranged on the inner side of the locking head 5, a pad 8 is sleeved on the outer side of the rotary lock rod 4 on the upper part of the quenching water spray device 7, a locking wrench 9 is arranged on the rotary lock rod 4 on the outer side of the pad 8, and a limiting member is arranged on the rotary lock rod 4 on the outer side of the locking wrench 9; the quenching water spray device is quickly fixed on the frame through the cooperation of the locking head and the locking hole, which greatly improves the work efficiency of installation and disassembly; even if there is a processing error in the frame or the quenching water spray device, a tight connection can be completed through the cooperation of the inclined surface A and the inclined surface B.

[0031] Specifically, a locking plate 10 is fixedly disposed on the frame 1 , a locking hole 2 is formed on the locking plate 10 , and an inclined surface A3 is disposed on the locking plate 10 to ensure that the lock head can pass through the locking hole 2 .

[0032] In this embodiment, the locking hole 2 is arranged in a strip-shaped structure and can be locked after being rotated.

[0033] It should be noted that a plane 11 is provided on the circumferential wall of one end of the rotary locking rod 4 away from the end lock head 5, and the locking wrench 9 includes a head 91 and a rod 92. The head 91 is provided with a through hole 93 whose shape is adapted to the plane 11 of the rotary locking rod 4, so as to facilitate the cooperation between the locking wrench and the rotary locking rod 4.

[0034] Furthermore, a plurality of insertion holes 12 are provided on the end face of the quenching water spray device 7, and the insertion holes 12 are provided with anti-loosening pins 16 for blocking the locking wrench 9 in a plug-in structure, so as to avoid the locking wrench from rotating and causing the locking device to open under the influence of a vibration environment, thereby improving the structural stability.

[0035] The rotating lock rod 4 located in the backing plate 8 is sleeved with a spring on the outside, and the two ends of the spring respectively contact the end surface of the quenching water spray device 7 and the end surface of the locking wrench 9. When unlocked, the lock head 5 is ejected in the lock hole 2, which is convenient and quick.
