Description
Technical Field
The invention relates to the technical field of trolleys, in particular to a shear type trolley height positioning device.
Background
In the current plastic industry, when a large-scale injection molding machine needs to replace a mold, the mold can be replaced only by a crane and manpower. The illegal operation of askew pulling and inclined hanging is easy to occur when the mold is replaced by the crane, and the condition that the mold damages machine tool equipment is easy to occur in the pulling process of the steel wire rope. On the other hand, because the pulling distance is difficult to control, an operator can operate the die completely according to the feeling of the operator, and the accident that the die slides down to the ground and hurts people due to improper force application is easily caused. In addition, moving large molds by manpower is time consuming and labor intensive.
The mold changing trolley is adopted to change the mold, so that quick mold changing can be automatically realized, insecurity and changing time existing in the process of changing the mold are reduced, and the workload of workers is reduced.
Therefore, the invention is necessary to develop a scissor type trolley height positioning device.
Disclosure of Invention
Aiming at the defects of the mold changing trolley in the prior art, the invention mainly aims to provide a scissor type trolley height positioning device.
In order to solve the technical problem, the invention provides a shear type trolley height positioning device which comprises a motor, a lead screw, a pressing plate, a guide roll shaft, a positioning plate, a lifting hydraulic cylinder, a shear type lifting frame, a controller, a mould and a laser distance measuring instrument, wherein the lead screw is arranged on the guide roll shaft; the motor is installed on the workstation of cutting the formula crane upper end, install a lead screw on the motor output shaft, with lead screw connection's round nut rigid coupling is on the clamp plate, and the mould setting is in on the workstation of cutting the formula crane, hydraulic cylinder installs cut on the formula crane, solenoid valve, motor on the hydraulic cylinder are connected with the controller electricity respectively, mould other end rigid coupling has a locating plate, and on the workstation of its left and right sides respectively the rigid coupling has one the motor, the rigid coupling has a laser distance measuring apparatu on the locating plate, laser distance measuring apparatu with the controller electricity is connected.
Preferably, the controller adopts a PLC singlechip.
Preferably, the motor is a stepping motor.
The laser distance measuring instrument is adopted to measure the distance from the mold to the mold changing position, the positioning precision in the height direction is high, the controller controls the stepping motor to stop running after the laser distance measuring instrument detects that the mold reaches the mold changing position, the positioning precision is high, and the use is convenient.
