Description

Technical Field

[0001] The utility model belongs to the technical field of casting, and particularly relates to a device for detecting viscosity of equiaxed crystal investment casting shell slurry. Background Art

[0002] At present, high-temperature alloy precision casting is completed by an automatic shell making line system, which greatly improves the efficiency of shell making and reduces the labor intensity of workers. However, since the current method of measuring the viscosity of the shell slurry is to measure it manually with a viscosity cup, the viscosity of the slurry cannot be automatically measured during the slurry dipping process and automation has not been achieved, resulting in a high degree of fluctuation in the consistency of the shell products. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a device for detecting viscosity of slurry in equiaxed crystal investment casting mold shells, which is a system capable of monitoring slurry viscosity during the process of slurry dipping in the mold shells, so as to improve the consistency and quality of the shell products.

[0004] A device for detecting the viscosity of equiaxed crystal investment casting shell slurry comprises a shell-making line transfer robot, the end effector of which is externally connected with a viscosity meter by bolts and electrically connected with a PLC master control system of the shell-making line part in the entire casting production line; a viscosity measuring probe of the viscosity meter is parallel to the end effector and can be immersed in the slurry during the slurry dipping process.

[0005] The shell making line uses an ABB robot as the robot for transfer.

[0006] The beneficial effects of the utility model are:

[0007] 1. The utility model realizes real-time monitoring of the viscosity of the slurry near the mold shell during the process of dipping the mold shell, can grasp the viscosity of each mold shell slurry in real time, improves the consistency and quality of the shell products, and solves the problem that the slurry viscosity cannot be automatically measured in the prior art.

[0008] 2. The utility model realizes the automation and intelligence of slurry viscosity detection through the shell making line rotation, viscosity measuring meter and its probe, and shell making rotation cylinder, improves the accuracy and efficiency of measurement, and reduces the error and labor intensity of manual operation.

[0009] 3. The utility model detects the viscosity of the slurry only during the period of dipping, which reduces the contamination of the slurry by the viscosity detection probe. At the same time, it also prolongs the service life of the viscosity probe and saves costs.

[0010] 4. In the utility model, the viscosity meter is connected to the PLC master control system of the shell making line. The PLC master control system can grasp the slurry viscosity in real time, and then perform calculation processing to determine whether it is qualified, thereby improving the safety and controllability of the shell making process.

[0014] In order to better explain the present invention and facilitate understanding, the technical scheme and effects of the present invention are described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0015] like Figure 1 As shown, a device for detecting the viscosity of slurry for equiaxed crystal investment casting shells includes a shell-making line transfer robot 1, which replaces manual work such as slurry dipping and sand pouring; the shell-making line transfer robot 1 adopts a commercially available ABB robot. The shell-making transfer cylinder is arranged in the slip ring device of the end effector 4 of the shell-making line transfer robot 1, and clamps and loosens the connecting rod on the shell by extending and retracting; the end effector 4 of the shell-making line transfer robot 1 is connected to the outside of a viscosity meter 3 by bolts, and is electrically connected to the PLC master control system of the shell-making line part of the entire casting production line. The viscosity measuring probe 2 of the viscosity meter 3 is parallel to the end effector 4 and can be immersed in the slurry during the dipping process.

[0016] During the shell making process, the shell is clamped by the shell making cylinder. While the shell making line robot 1 performs the slurry dipping process, the viscosity measuring probe 2 of the viscosity meter 3 extends into and immerses in the slurry to detect the viscosity of the slurry in real time, and feeds back its measured value to the PLC master control system. The PLC master control system performs calculations and processing. If the viscosity of the slurry does not meet the preset standard, the PLC master control system will issue an alarm and automatically execute the corresponding processing flow.
