Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to fig. 1 and 2, the clamp control and protection device of the profiling milling flying saw of the present embodiment is symmetrically arranged, and includes a motion controller (not shown in the drawings, and the whole system of the profiling milling flying saw is only one motion controller), a magnetic scale (including a magnetic reading head 2 and a magnetic scale), a clamp support 4, a clamp block sliding seat 5, a clamp block 6, and a hydraulic cylinder 7;
wherein, the read head 2 of the magnetic grid ruler is fixed on the clamp bracket 4 through the magnetic head fixing seat 3.
The magnetic scale of the magnetic grid scale is connected with the clamp block slide carriage 5 below the clamp bracket 4 through the fixing frame of the magnetic scale. Preferably, the clamp bracket 4 is provided with a through hole, and the magnetic scale passes through the through hole on the clamp bracket 4 and is connected with the clamping block sliding seat 5.
The read head 2 is relatively displaced on the magnetic scale, and the read head 2 converts the magnetized data signal recorded on the magnetic scale into an electronic signal and transmits the electronic signal to a circuit to complete displacement measurement.
The read head 2 is connected to a motion controller. Specifically, the read head 2 is connected to the motion controller through a circuit connection line.
The upper part of the clamping block sliding seat 5 is also connected with a hydraulic cylinder 7, the lower part of the clamping block sliding seat 5 is connected with a clamping block 6, and the hydraulic cylinder 7 drives the clamping block 6 on the clamping block sliding seat 5 to move up and down.
The upper and lower clamping blocks 6 which are symmetrically arranged move simultaneously, so that the straight welded pipe is clamped or loosened simultaneously.
The motion controller in this embodiment is a CT-III motion controller of shenyang kat electromechanical devices ltd, which is directly available on the market; the motion controller can also be applied to controllers of other manufacturers, such as those of Siemens.
The motion controller is electrically connected with an electromagnetic valve of the hydraulic cylinder 7, and controls the hydraulic cylinder 7 to drive the clamping block sliding seat 5 to move up and down.
In addition, the motion controller can clamp the clamp in advance through the hydraulic cylinder 7 and the clamping block sliding seat 5, so that the clamping distance is reduced, the clamping time is further shortened, and the production speed is increased. That is, the motion controller can drive the clamp block 6 on the clamp block sliding seat 5 to move downwards for a certain distance in advance through the hydraulic cylinder 7, so that less time is needed when the next clamping action is completed.
The clamp control and protection device of the embodiment is used as follows:
when the hydraulic cylinder 7 drives the clamp (specifically, the clamp block sliding seat 5) to act, the magnetic scale also acts along with the clamp block sliding seat 5, the magnetic scale and the read head 2 generate relative displacement, the read head 2 converts displacement information into a digital pulse signal through an internal detection circuit, the digital pulse signal is connected with a high-speed pulse input port of the motion controller through a circuit, the motion controller converts the counting of the digital pulse signal into the position of the clamp (the clamp block sliding seat 5), and judges whether the clamp is in a clamping or unclamping state according to the position of the clamp block sliding seat 5 (if the position of the clamp block sliding seat 5 is moved down to a certain position, the clamp 6 is moved down, and then the two clamp blocks 6 finish clamping and fixing the straight welded pipe together, so that the clamp is in the clamping state).
Before the flying saw of the profiling milling flying saw returns, the clamp is in a loose clamp state (namely, when the position of the clamp block sliding seat 5 moves to a certain position, the clamp block 6 moves upwards, and the two clamp blocks 6 cannot clamp and fix the straight welded pipe together), or else, the clamp is automatically withdrawn, and an alarm is given.
The above description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
