Description

Technical Field

[0001] The utility model relates to the technical field of position detection, in particular to a vacuum molding roller positioning device. Background Art

[0002] Vacuum molding is a fully physical molding method. Its basic principle is to fill the sand box with dry quartz sand, seal the sand box with plastic film, and then evacuate it, and use the pressure difference inside and outside the mold to make the molding sand compact and molded. The empty box return roller is a commonly used equipment in the automatic vacuum molding line, which is used to transfer the empty sand box from one station to another. The positioning mechanism on the empty box return roller is mainly used for the empty box grabbing manipulator to accurately grab the empty sand box on the empty box roller. The existing positioning mechanism is not accurate enough and has a high failure rate. In the automatic vacuum molding process, the empty sand box is transported to the empty box hanging position through the roller. The empty box return roller is mostly controlled by an ordinary reducer. After the roller stops, the positioning is often inaccurate, which makes it impossible for the empty box grabbing manipulator to automatically grab the box quickly and accurately. The reducer is driven. Even after it is in place, the empty sand box will swing back and forth due to inertia, and the position will deviate. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a vacuum molding roller positioning device which carries and transports an empty sand box through a transportation device, intercepts, carries and positions the empty sand box through a resetting device, and automatically rebounds to its original position after the empty sand box is detached. The empty sand box can be directly transported to the resetting device through the positioning structure, thereby improving the positioning accuracy and practicality of the equipment.

[0004] The utility model discloses a vacuum molding roller positioning device, which comprises a transport device, a reset device and a positioning structure, wherein the reset device is installed on the transport device and the positioning structure is arranged on the reset device; an empty sand box is carried and transported by the transport device, and the empty sand box is intercepted, carried and positioned by the reset device, and automatically rebounds to its original position after the empty sand box is detached, and the empty sand box can be directly transported to the reset device by the positioning structure, thereby improving the positioning accuracy and practicality of the equipment.

[0005] Preferably, the transport device includes a frame and motorized rollers, and a plurality of sets of motorized rollers are installed on the upper end surface of the frame through brackets, and the plurality of sets of motorized rollers are driven by reducers; the empty sand box is transported by the plurality of sets of motorized rollers, and a reset device is installed on the frame close to one side of a set of motorized rollers, and the empty sand box is quickly positioned during transportation by cooperating with the transport device and the reset device.

[0006] Preferably, the reset device includes a mounting bracket, a push rod, a compression spring and a positioning claw. The mounting bracket is mounted on the frame, and the upper part of the push rod is inserted into the interior of the mounting bracket and can move up and down in the mounting bracket. The compression spring is sleeved on the upper part of the push rod, and the top end surface of the push rod is connected to the lower end surface of the positioning claw. The empty sand box on the transport device is intercepted by the positioning claw and the empty sand box is carried and quickly positioned. The compression spring is used to provide elastic force for the positioning claw. After the empty sand box on the positioning claw is taken out, the positioning claw is lifted upward to the upper side of the motorized roller, thereby realizing automatic return without the need for electric drive return, thereby improving the practicability of the device.

[0007] Preferably, it also includes a proximity switch, which is installed at the lower part of the frame; when the positioning claw intercepts the empty sand box and drives the push rod to fall, the proximity switch senses the push rod and controls the reducer of the transportation device to stop working, thereby preventing the subsequent empty sand boxes from continuing to be transported and causing accumulation and collision between materials; when the empty sand box on the positioning claw is taken out, the push rod rises upward with the positioning claw, and at this time the proximity switch controls the transportation device to start and continue to transport the remaining empty sand boxes, thereby improving the degree of automation and practicality of the device.

[0008] Preferably, the positioning structure includes an inclined baffle, a positioning groove and a vertical baffle, a positioning groove is provided in the middle of the positioning claw, an inclined baffle is provided on the upper part of the positioning groove close to the feeding side of the frame, and a vertical baffle is provided on the side of the positioning groove away from the feeding side of the frame, and the side of the vertical baffle is a vertical plane; when the transportation device transports the empty sand box to the position of the positioning claw, the empty sand box squeezes the inclined baffle to drive the positioning claw to fall, and then drives the push rod to move downward to trigger the proximity switch to control the transportation device to stop operating. At this time, the empty sand box on the motorized roller will fall into the positioning groove due to inertia, and the position of the empty sand box is accurately located by the positioning groove, and the empty sand box is intercepted by the vertical baffle to prevent the empty sand box from flipping out of the positioning claw too fast, thereby improving the practicability of the device.

[0009] Compared with the prior art, the utility model has the following beneficial effects: the empty sand box is carried and transported by the transport device, the empty sand box is intercepted, carried and positioned by the reset device, and the empty sand box automatically rebounds to its original position after being detached; the empty sand box can be directly transported to the reset device through the positioning structure, thereby improving the positioning accuracy and practicality of the equipment.

[0017] First, the empty sand box 11 is transported by multiple sets of motorized rollers 2. Then, when the transport device transports the empty sand box 11 to the position of the positioning claw 7, the empty sand box 11 squeezes the inclined baffle 8 to drive the positioning claw 7 to fall, and then drives the push rod 4 to move downward, triggering the proximity switch 6 to control the transport device to stop operating. At this time, the empty sand box 11 on the motorized roller 2 will fall into the positioning groove 9 due to inertia, and the position of the empty sand box 11 is accurately positioned by the positioning groove 9. The empty sand box 11 is intercepted by the vertical baffle 10 to prevent the empty sand box 11 from turning out of the positioning claw 7 too fast. When the empty sand box 11 on the positioning claw 7 is taken out, the push rod 4 follows the positioning claw 7 to rise upward.
