Heavy high-speed precise press body locking mechanism

Abstract

The invention relates to a heavy high-speed precise press body locking mechanism, comprising a locking screw rod (1); the locking screw rod (1) is arranged in each machine body (2) to be tensioned in a penetrating mode; the locking screw rod (1) is provided with a locking nut (3) positioned at the machine body (2) at the bottommost end; the locking screw rod (1) is provided with a locking device (4) positioned at the upper part of the machine body (2) at the topmost end; the structure of the locking device comprises pistons (41) fixedly connected with the locking screw rod (1) and cylinder bodies (42) connected with the machine body (2) at the topmost end; the cylinder bodies (42) are arranged at the outer sides of the pistons (41) and forms hermetical match. The locking for the machine bodies is realized by matching the locking nut and the locking device, and the locking device on the upper part of the corresponding machine body drives the locking screw rod to further drive the locking nut to upwards move, so the machine bodies are locked, the structure is simple and the locking is reliable.

Description

technical field [0001] The invention relates to a body locking mechanism of a heavy-duty high-speed precision press, which belongs to the technical field of presses. Background technique [0002] In the existing domestic press technology, two structures are used for the locking of the split fuselage of the general press. One kind of self-made oil cylinder tightens the screw rod, that is, both ends of the screw rod are lock nuts, but the screw rod is lengthened. One end uses the oil cylinder to apply a specified load to the tie rod and the fuselage, and then rotates the lock nut under the oil cylinder, and then loosens the oil cylinder to achieve the purpose of locking the split fuselage. The advantage is that the structure is simple; the disadvantage is that multiple tensioning screws need to be operated separately, and professional tooling is required; there is also a pull rod electric heating method, which connects the pull rod to a specified current, and uses the principl...

Problems solved by technology

The advantage is that the structure is simple; the disadvantage is that multiple tensioning screws need to be operated separately, and professional tooling is required; there is also a pull rod electric heating method, which connects the pull rod to a specified current, and uses the principle of thermal expansion and cold contraction to make the pull rod elongate. Rotate the lock nut to achieve the purpose of locking the split body

The advantage is that the structure is simple, and the disadvantage is that the operation is complicated, the safety is poor, and the operation skills are required to be professional.
