Description
Technical Field
The utility model relates to a press, in particular to press ram locking mechanism.
Background
The ram in the press is a key part for transferring power of the press, and is used for connecting a crankshaft, a connecting rod and a slide block of the press and transmitting the rotary motion of the crankshaft to the slide block to do reciprocating linear motion, but the ram can move up and down when the crankshaft does the rotary motion, so that the power transfer of the press can be influenced, the slide block is often not in place when the slide block does the reciprocating linear motion, and the ram can move up and down to possibly damage the press and even cause safety accidents.
Therefore, further improvements are needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a press ram locking mechanism that sound construction, safe and reliable, practicality are strong to overcome the weak point among the prior art.
According to a press ram locking mechanism of this purpose design, the press includes bent axle and connecting rod, the bent axle is connected with the connecting rod, the ram is connected on the connecting rod, locking mechanism sets up in one side of connecting rod its characterized in that: the locking mechanism comprises a gland, a locking block and a locking screw, the gland is arranged on the outer side of the connecting rod, the locking block is arranged in a through hole in the side portion of the connecting rod and located between the plunger rod and the gland, and the locking screw penetrates through the gland and then presses the locking block tightly, so that the plunger rod is locked by the locking block.
After the plunger rod is locked, a gap is reserved between the locking block and the gland, the depth of the gap is a, and a is 0.9-1.1 mm.
The connecting rod is provided with a gland fixing hole, and the gland is fixed on the connecting rod through a fastening element arranged on the gland fixing hole.
And a spring washer with a buffering function is arranged between the fastening element and the gland.
The punch comprises a screw and a ball head body, the screw is arranged on an inner hole of the connecting rod, and the ball head body protrudes out of the connecting rod and is connected with a sliding block on the press.
The utility model discloses a set up locking mechanism on the connecting rod of press, utilize locking screw to compress tightly the latch segment, rethread latch segment is with the jumper bar locking, prevents that the press during operation jumper bar from taking place to reciprocate and influence the power transmission of press, even take place the incident, and it has characteristics that sound construction, safe and reliable, practicality are strong.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to fig. 1-4, the press ram locking mechanism comprises a crankshaft 1 and a connecting rod 2, the crankshaft 1 is connected with the connecting rod 2, a ram 3 is connected with the connecting rod 2, the locking mechanism is arranged on the front side of the connecting rod 2, the locking mechanism comprises a gland 4, a locking block 7 and a locking screw 6, the locking screw 6 is a hexagon socket screw, the gland 4 is arranged on the outer side of the connecting rod 2, the locking block 7 is arranged in a through hole in the side part of the connecting rod 2 and is positioned between the ram 3 and the gland 4, the locking screw 6 presses the locking block 7 after penetrating through the gland 4, so that the locking block 7 locks the ram 3, and the situation that the power transmission of the press is influenced by the fact that the ram 3 moves up and down when the press works is prevented, and even the press is damaged and has safety.
Furthermore, after the plunger 3 is locked, a gap is left between the locking block 7 and the gland 4, and the depth of the gap is a, wherein a is 0.9 mm-1.1 mm.
Furthermore, a gland fixing hole is arranged on the connecting rod 2, and the gland 4 is fixed on the connecting rod 2 through a fastening element 5 arranged on the gland fixing hole.
Further, the fastening element 5 comprises a double-ended bolt and nut 5.1, and a spring washer 8 with a buffering function is arranged between the nut 5.1 and the gland 4.
Furthermore, the punch 3 comprises a screw 3.1 and a ball head body 3.2, the screw 3.1 is arranged on an inner hole of the connecting rod 2, and the ball head body 3.2 protrudes out of the connecting rod 2 and is connected with a slide block on the press.
The foregoing is a preferred embodiment of the present invention showing and describing the basic principles, main features and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are intended to illustrate the principles of the invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and the scope of the invention is to be protected. The scope of the invention is defined by the appended claims and equivalents thereof.
