Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grinding machines, in particular to a sand core automatic detection grinding machine. Background Art
[0002] The socket forming of ductile iron pipe is closely related to the shape of sand core, so the quality of sand core directly determines the quality of pipe socket. In the process of sand core manufacturing, in order to ensure the forming rate, there is often more sand on the top, which is the sand core burr that needs to be ground. The traditional grinding method relies on angle grinder, which not only increases labor cost and production cost, but also reduces the production rhythm. What's more serious is that if the grinding is excessive, the surface of sand core may be damaged, causing the produced pipe to become waste, which will bring greater economic losses.
[0003] In addition, the sand cores produced sometimes have sand pits on their surface. If such sand cores with sand pits are used in production, protruding residual iron will appear inside the pipe socket, seriously affecting the qualification of the product. Because the inside of the socket of a qualified pipe should be smooth, these protruding residual iron must be polished, which undoubtedly increases the complexity and cost of production.

DETAILED DESCRIPTION
[0011] Please refer to the attached Figure 1 Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.
[0012] The utility model proposes an automatic sand core inspection and grinding machine, comprising a first bracket 3, a motor 5 is fixedly installed inside the first bracket 3, the motor 5 is connected to a slewing support 4 through an output shaft, a sand core rotating device 2 is installed on the top of the slewing support 4, and a detection device and a grinding device are installed on one side of the top of the first bracket 3. A sand core 1 is installed on the top of the sand core rotating device 2 through a sand core fixing device 13, the installation position of the sand core fixing device 13 can be adjusted according to the size of the actual sand core 1, and a proximity switch 6 is installed on one side of the sand core rotating device 2. The detection device comprises a second bracket 7 and a 3D smart camera 8, and a 3D smart camera 8 is installed on the top of the second bracket 7. The 3D smart camera 8 can detect, identify and image the surface defects of the sand core 1, and can capture the shape, size and surface characteristics of the target object more comprehensively and accurately by using its three-dimensional visual function.
[0013] The grinding device includes a third bracket 9, a horizontal moving device 10, a vertical lifting device 11 and a pneumatic grinding head 12. The top of the third bracket 9 is equipped with a horizontal moving device 10, and the horizontal moving device 10 is equipped with a vertical lifting device 11 at one end close to the sand core 1, and the pneumatic grinding head 12 is installed at the bottom of the vertical lifting device 11. The sand core 1 is deburred by the grinding device. The horizontal moving device 10 can drive the vertical lifting device 11 and the pneumatic grinding head 12 to move horizontally. The purpose of the vertical lifting device 11 is to drive the pneumatic grinding head 12 to move vertically, and the drive and sliding can be achieved by using a cylinder combined with a slide rail.
[0014] Working principle:
[0015] After the sand core 1 is placed, the 3D smart camera 8 starts working, and the motor 5 rotates to drive the sand core rotating device 2 and the sand core 1 to rotate. When the proximity switch 6 detects that the sand core 1 has rotated a full circle, the motor 5 stops rotating, and the 3D smart camera 8 analyzes the scanned image to determine whether there are defects greater than the set range. If there are defects, a signal will be sent to the PLC, and the PLC will judge the sand core 1 as scrap.
[0016] After the sand core 1 is placed on the sand core rotating device 2, the horizontal moving device 10 drives the pneumatic grinding head 12 and the vertical lifting device 11 to reach above the sand core 1, and the vertical lifting device 11 drives the pneumatic grinding head 12 to descend. When it is about to touch the deburring surface of the sand core 1, the pneumatic grinding head 12 starts to rotate. After reaching the deburring surface, the motor 5 starts to rotate, driving the sand core rotating device 2 and the sand core 1 to rotate. After the sand core 1 rotates one circle, the motor 5 and the pneumatic grinding head 12 stop rotating, and the vertical lifting device 11 drives the pneumatic grinding head 12 to rise. After rising into place, the horizontal moving device 10 drives the pneumatic grinding head 12 and the vertical lifting device 11 to retreat into place, and the deburring work of the sand core 1 is completed.
