Embodiment 1

[0050] see Figure 1-13 , a large-scale die casting mold cavity surface temperature and crack automatic detection device of the present embodiment, comprising:

[0051] Frame 1, the output shaft end of the frame is fixedly provided with a connection frame 10, the frame 1 can drive the connection frame 10 to move horizontally and vertically and is provided with a first drive mechanism for controlling the rotation angle of the connection frame 10 in the connection frame 10 ;

[0052]Wherein, the frame 1 comprises a frame base 11, and a flat workbench 14 is arranged above the frame base 11, and the flat workbench 14 drives its longitudinal displacement by the first screw nut mechanism arranged on the frame base 11, And the leading screw of the first leading screw and nut mechanism drives its rotation by the first stepper motor 301, specifically, the first leading screw and nut mechanism includes the leading screw 12 that is rotated on the frame base 11, and the flat workbench 14...

Embodiment 2

[0072] Compared with Embodiment 1, this embodiment is used as an example of the third drive mechanism: the third drive mechanism control includes T-shaped fixed brackets 200 respectively installed on the opposite sides of the first reflector 101, and the T-shaped fixed bracket 200 is horizontal. There is a groove on the side, and the first reflector 101 is fixedly installed in the groove. The two sides of the T-shaped fixed bracket 200 are set as cylindrical shafts that cooperate with the main frame of the starting end acquisition unit, and one of the cylindrical shafts has a structure that passes through the main frame of the starting end acquisition unit. The extended end of one side side wall is fixed with the first bevel gear 201 on the extended end, and a fourth stepping motor 304 is fixed on the side plate of this side simultaneously, and the output shaft of the fourth stepping motor 304 is fixed with The second bevel gear 204 meshing with the first bevel gear 201

Abstract

The invention discloses an automatic detection device for the surface temperature and cracks of the mold cavity of a large pressure casting mold. It includes a frame, a connection frame driven by the frame, and a CCD camera mechanism and a penetrating image reflection device are fixedly arranged on the connection frame. The frame is used to adjust the spatial position of the CCD camera and the penetrating image reflection device; the CCD camera mechanism can adjust the angle of the CCD camera to accept image adjustment; unit and the end fixed unit, in which the start acquisition unit and the tail end fixation unit can collect the image and transmit it to the control of the incident angle of the CCD camera, and the intermediate transfer unit can pass the color and shape of the mold cavity through multiple The secondary reflection is transmitted to the CCD camera. Through image processing, the temperature and cracks on the surface of the mold cavity of the equipment can be identified to solve the problem of temperature and crack detection on the surface of the mold cavity.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to an automatic detection device for the surface temperature and cracks of a large pressure casting mold cavity, which is used for the surface temperature and cracks of a large pressure casting mold cavity. Background technique [0002] In recent years, under the guidance of the concept of energy saving and emission reduction, the application share of lightweight non-ferrous alloy die-casting parts in actual production and life has continued to increase, and the output of large-scale die-casting parts in China has continued to rise. [0003] The cavity shape of the die casting mold is generally more complex, and it is subjected to pressure during the production process of the part, and at the same time, due to the continuous change of temperature, it is easy to crack in the transition zone. In order to ensure the service life of the die-casting mold and at the same time ...
