[0002] Casting is one of the earliest metal heat treatment processes mastered by mankind, with a history of about 6,000 years. China entered the heyday of bronze casting between 1700 and 1000 BC, and the technology had reached a very high level. Casting is a method of pouring liquid metal into a casting cavity that conforms to the shape of the part, and then cooling and solidifying it to obtain the part or blank.

[0003] Castings produced by casting need to be inspected before leaving the factory to check for defects such as appearance defects and burrs. Currently, the most widely used inspection method is manual inspection. In manual inspection, castings are usually transported to the inspection station by a transfer tool, and then workers take them out one by one from the transfer tool and place them on the table for inspection. This process requires workers to repeatedly bend over to pick up and place them on the table for inspection, which is labor-intensive and affects the overall inspection efficiency.

[0004] Therefore, the inventor sought to solve the problem of designing an electric tilting transfer vehicle to tilt castings, reduce the number of workers picking up workpieces, lower labor intensity, and improve efficiency. Utility Model Content

Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0020] Example 1: See Figures 1 to 2 This is a structural view and internal structural view of the present invention. A workbench for casting quality inspection includes a support frame 1, which is a steel structure composed of a metal frame. A limiting beam 7 is provided on the inner side of the left end of the support frame 1. The function of the limiting beam 7 is to limit the angle at which the transfer cart 9 flips towards the table surface 16 when the transfer cart 9 is flipped, so as to avoid the transfer cart 9 overturning excessively and falling onto the table surface 16 and injuring people in case of failure.

[0021] A mounting bracket 3 is provided on the inner top of the support frame 1. The mounting bracket 3 is connected to an electric hoist 2. A chain is provided at the output end of the electric hoist 2. The end of the chain is connected to a hook 5 via a hook 4. Two symmetrically distributed reinforcing plates 10 are provided on the inner left side of the support frame 1. A U-shaped groove is provided on the inner end face of the reinforcing plate 10. The thickness of the U-shaped groove 11 is less than the length of the limiting rotating shaft 13 and not less than 4cm. A transfer cart 9 is provided on the inner side of the support frame 1. A lifting bracket 8 is provided on the right end of the transfer cart 9. A lifting ring 6 is provided on the upper end of the lifting bracket 8. The hook 5 is hooked and connected to the lifting ring 6. Pads 12 are provided on both sides of the left end of the transfer cart 9. A limiting rotating shaft 13 is provided at the edge of the pad 12. The limiting rotating shaft 13 is engaged with the U-shaped groove and rotated.

[0022] The left end of the support frame 1 is connected to the inspection table 14. The inner side of the inspection table 14 is provided with a non-conforming product display platform 15 for placing non-conforming products. The middle part of the inspection table 14 is provided with a tabletop 16, which is L-shaped. One side of the tabletop 16 is connected to the left end of the transfer cart 9. The lower end of the tabletop 16 is provided with a tool compartment 17 for storing quality inspection tools. The right end of the tool compartment 17 is provided with a hanging plate 18, on which the remote control of the electric hoist 2 is installed. The transfer cart 9 enters the support frame 1 from the right end of the support frame 1. During the entry process, the angle needs to be adjusted so that the limiting rotation shaft 13 is accurately engaged in the inner side of the U-shaped slot 11, so that the limiting rotation shaft 13 and the U-shaped slot 11 form a hinged connection. After the hook 5 is manually operated and hooked on the lifting ring 6, the quality inspector returns to the work station to complete the work.

[0023] Personnel manually operate the remote control of the electric hoist 2, which is mounted on the hanging plate 18, to control the electric hoist 2 to retract its chain. When the chain retracts, it causes one side of the lifting bracket 8 of the transfer cart 9 to rise and rotate counterclockwise around the limit rotation axis 13. The rotation angle during the rotation is determined by the length of the chain on the electric hoist 2 controlled by the personnel. As the lifting bracket 8 gradually rises, the castings inside the transfer cart 9 gradually move closer to the end of the left side wall of the transfer cart 9 until some castings fall from the left end of the transfer cart 9 onto the table 16, at which point the chain retraction stops, making it convenient for quality inspectors to retrieve the workpieces.

[0024] The left side wall of the transfer vehicle 9 forms a 35° angle with the vertical direction and the upper end is tilted to the left. The four sides and bottom side walls of the transfer vehicle 9 are all mesh structures, and wheels are provided at the bottom corners of the transfer vehicle 9.

[0025] To prevent castings from falling through the gap between the transfer car 9 and the platform 16 due to excessive gaps, the transfer car 9 is further configured such that when it rotates 55° around the limiting rotation axis 13, the left side wall of the transfer car 9 is parallel to the horizontal plane and the gap between the end and the platform 16 is no more than 10cm.

[0026] The transfer vehicle 9 does not contact the crossbeam of the support frame 1 when it rotates.

[0027] This utility model adopts a support frame 1 with an electric hoist 2 suspended on top. The electric hoist 2 can be controlled by a remote control to control the transfer cart 9 that is hooked together with the hook 5 to rotate around the limit rotation shaft 13, so that one side is flipped up. The angle of flipping up can be controlled at any time to control the degree of tilting of the internal castings, making it easier for quality inspectors to pick up the castings for inspection. It realizes the function of electric tilting transfer cart 9 to tilt the castings, reduce the work of workers picking up workpieces, reduce labor intensity and improve efficiency.
