Description

Technical Field

[0001] The utility model relates to the technical field of casting cooling, and more specifically, to a machine tool casting cooling device. Background Art

[0002] Machine tool castings can also be called large castings, bed, base, workbench, etc., which are characterized by good wear resistance, shock absorption and good process performance. Machine tool castings are one of the core components of machine tools and are also a very important part; during the manufacturing process, machine tool castings need to be processed at high temperature. After high temperature processing, a special device is required to cool them down. For this purpose, a machine tool casting cooling device is proposed.

[0003] After exploration, for example, a Chinese patent application with application number CN202222587316.8 discloses a machine tool casting cooling device. By setting a cooling mechanism, the cooling effect of the machine tool casting can be improved, the cooling speed of the machine tool casting can be increased, the cooling time can be saved, and the processing efficiency of the machine tool casting can be improved; since the cooled machine tool castings need to be rotated between multiple cooling pools, the machine tool castings can be moved by setting a moving mechanism, thereby improving the flexibility of the overall device, avoiding manual movement of the machine tool castings, and improving practicality; by setting a lifting mechanism, the staff can lift, move and cool down multiple machine tool castings, shortening the processing time of machine tool components and improving the overall processing efficiency of machine tool castings.

[0004] However, when the above technical solution is in use, the steel wire rope and the placement basket are hoisted and moved. The steel wire rope will swing during the movement, so it is necessary to wait for the placement basket to be vertical before it can be lowered. In addition, the steel wire ropes are arranged on all four sides of the upper end of the placement basket, which is not convenient for loading. The cooling efficiency is not ideal when the cold air flow is infused through the cold air cavity to cool the three cooling pools. In addition, the use of three cooling pools will also lead to a higher cost for the overall structure. Utility Model Content

[0016] Technical effects and advantages of the utility model:

[0017] 1.

[0026] In order to improve the cooling efficiency, a circulating water cooling device 2 capable of realizing water cooling is provided on the upper end of the operating table 1, which is used to cool the cooling water in a recycling manner;

[0027] like Figure 3 As shown, the circulating water cooling device 2 includes a cold water tank 21, which is fixedly arranged at the upper end of the operating table 1. A circulating water chiller 22 is fixedly arranged on one side of the cold water tank 21. The output end and the input end of the circulating water chiller 22 pass through one side of the cold water tank 21. The output end and the input end of the circulating water chiller 22 are jointly fixedly provided with a threaded heat exchange tube 23. A drain pipe 24 is fixedly arranged on one side of the cold water tank 21. Cooling water is poured into the cold water tank 21, and the coolant in the threaded heat exchange tube 23 is circulated and cooled by the circulating water chiller 22, thereby achieving the effect of circulating cooling of the cooling water in the cold water tank 21. When the cooling water needs to be replaced, it is discharged through the drain pipe 24. The cooling water is heat-exchanged and cooled by the direct contact between the threaded heat exchange tube 23 and the cooling water as a whole, thereby improving the cooling efficiency.

[0028] Furthermore, in order to keep the casting clamped and moved smoothly, a clamping and moving device 3 capable of clamping the casting and moving it is provided at the upper end of the operating table 1, which is used to keep the casting clamped and moved smoothly and place the casting in a cold water tank 21 for cooling;

[0029] like Figure 4As shown, the clamping moving device 3 includes a threaded sleeve 32, which is threadedly connected to the outer surface of the threaded rod 6, a moving block 31 is fixedly arranged on the outer surface of the threaded sleeve 32, a groove on one side of the moving block 31 is penetrated by the limiting sliding rod 7, a cylinder 33 is fixedly arranged on the upper end of the moving block 31, a top plate 34 is fixedly arranged on the upper end of the cylinder 33, two connecting rods 35 are fixedly arranged on both sides of the lower end of the top plate 34, both connecting rods 35 penetrate the moving block 31, the outer wall of the connecting rod 35 contacts the inner side of the moving block 31, a clamp frame 36 is fixedly arranged on the lower end of the connecting rod 35, a slow-moving motor 37 is fixedly arranged on the inner groove of the clamp frame 36, the output end of the slow-moving motor 37 penetrates the lower end of the groove of the clamp frame 36, and the output end of the slow-moving motor 37 penetrates the lower end of the groove of the clamp frame 36.
