Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1, a batten with the same size is made at the same position of the upper parting surface and the lower parting surface in the flaskless molding sand frame, a groove 15 is formed in the outer side of the sand mold after stripping, the groove 15 is arranged in half at the joint of the outer surfaces of an upper mold 13 and a lower mold 14, and whether the upper mold 13 and the lower mold 14 are aligned or not can be visually seen through the method by naked eyes.
When observing alignment which cannot be detected by naked eyes, the following scheme is adopted:
referring to fig. 2-4, the electric slide rail 1 is provided with at least one fixed angle iron 2 for fixed installation, and the fixed angle iron 2 is installed on the ground through an expansion bolt.
The walking base 4 is used for placing the upper die 13 and the lower die 14, the walking base 4 is positioned on the electric sliding rail 1, and the electric sliding rail 1 provides power to reversely move along the electric sliding rail.
Detection component sets up on electronic slide rail 1, and detection component is used for detecting the alignment condition of last mould 13 and lower mould 14 when walking base 4 moves, and the specific setting and the principle of detection component will be explained in detail mutually:
referring to fig. 2 and 3, the detection assembly includes a detection frame 3, a laser emitter 11, a photosensitive assembly 5, a displacement driving assembly and a power assembly 12, and the specific connection mode is as follows:
the detection frame 3 is installed on the electric slide rail 1, the detection frame 3 is located on the side face of the electric slide rail 1, and the detection frame and the electric slide rail can be connected in a welding or bolt fixing mode.
The laser transmitter 11 is used for transmitting modulated laser, and can continuously transmit laser of 200 KHZ. It should be noted that the light emitted by the laser emitter 11 is close to the traveling base 4 and the lower die 14, i.e. the lower die 14 is aligned with the traveling base 4 when loaded thereon, so as to provide a precondition for the subsequent alignment detection of the upper die 13 and the lower die 14.
The photosensitive assembly 5 is used for sensing modulated laser emitted by the laser emitter 11 and raising the pin level when receiving the laser, and the photosensitive assembly 5 is composed of a light absorption shell 51, a total reflection mirror 52, a semi-transparent mirror 53 and a photosensitive element 54. Refer to fig. 4.
The light absorption shell 51 is arranged at the top end of the detection frame 3 and is parallel to the side face of the walking base 4, and the parallel arrangement ensures the accuracy of detection.
The outer surface of the light-absorbing shell 51 may be printed with black ink so that the inner wall thereof may absorb stray light from the outside.
The light absorption shell 51 adopts a semi-open structure and has an opening facing the laser emitter 11, the total reflection mirror 52 is arranged at the inner bottom end of the light absorption shell 51, and the semi-transparent mirror 53 is arranged at the opening of the light absorption shell 51. After passing through the semi-transparent mirror 53, the laser is continuously reflected between the semi-transparent mirror 53 and the total reflection mirror 62 until being received by the photosensitive element 54, the photosensitive element 54 can adopt a photodiode, can output a low level in a normal state, and can raise the pin level when receiving the laser, the pin level can be continuously monitored through the MCU, so that whether the current laser is shielded or not is judged through the change of the level, and whether the upper die 13 and the lower die 14 in motion are aligned or not is determined.
The laser emitting angle of the laser emitter 11 is deflected from the vertical direction by 10 ° to 60 ° (refer to fig. 4, which is an exemplary illustration of light paths without two angles of 10 ° and 60 °), when the deflected angle is smaller, the light is lost more in continuous reflection, so that the sensitivity of the device is reduced, and when the deflected angle 60 is increased, a reflection blind zone may exist, so that the deflected angle should be selected according to the length of the light-absorbing shell 51, and the deflected angle is reduced as much as possible while ensuring that the light-sensing element 5 can sense the light.
Referring to fig. 2 and 3, a displacement driving assembly is provided on the inspection frame 3 for adjusting the position of the laser transmitter 11, the displacement driving assembly including: ball 7, ball nut 6, polished rod 8, linear bearing 9 and laser emitter mount pad 10 specifically as follows:
the two ends of the ball screw 7 are arranged on the detection frame 3 through bearings, and the ball nut 6 is in threaded connection with the ball screw 7.
Both ends of the light bar 8 are welded on the detection frame 3, and the linear bearing 9 is connected with the light bar 8 in a sliding way.
A laser transmitter mount 10 is used to mount a laser transmitter 11, and a ball nut 6 and linear bearing 9 are also mounted on the laser transmitter mount 10.
The power assembly 12 is mounted on the electric slide rail 1, and the power assembly 12 is used for supplying power to the displacement driving assembly, and in the embodiment, the power assembly 12 is composed of a servo motor and a speed reducer (refer to fig. 2).
Example two
In this embodiment, the quantity of determine module is two, and two determine module symmetries set up in electronic slide rail 1 both sides, carry out synchronous detection, and it is fixed through link 16 between two laser emitter mount pads 10 to realize two determine module sharing power component 12.
Wherein ball 7 and ball nut 6 in the detection module that is not directly connected with power component 12 replace for polished rod 8 and linear bearing 9, because only ball 7 that is connected with power component 12 is thought of, so with ball 7 and the ball nut 6 replacement of the opposite side, two polished rods and laser emitter mount pad 10 sliding connection to reduce the movement resistance of opposite side laser emitter mount pad 10, improve stability.
The above description is only a preferred embodiment of the present invention, and not intended to be exhaustive or to limit the scope of the present invention, and any person skilled in the art should be able to make equivalents and modifications within the technical scope of the present invention.
