Detailed Description

Example 1

As shown in FIG. 1, a pressing fixture comprises a cylinder 4, a sliding block 6, a pressing block seat 7 and a supporting seat 2. One end of the supporting seat 2 is connected with the base 1, the other end is connected with the fixed plate 3, the fixed plate 3 is horizontally and oppositely distributed with the base 1, the fixed plate 3 is provided with the air cylinder 4, the air cylinder 4 is erected above the base 1, the base 1 is provided with a positioning groove 9 for positioning a device to be pressed, and the telescopic end of the air cylinder 4 is connected with the adapter 5.

As shown in fig. 2, the support base 2 is embedded with the chute board 12, so that the front surface of the chute board 12 is exposed out of the support base 2 and is clamped with the chute board 11, the chute board 11 can slide up and down, the back surface of the chute board 12 is positioned in the support base 2, the support base 2 is hollow, a heat dissipation component is installed in the support base 2 near one side of the chute board 12 and is used for cooling the chute board 12, and the chute board 11 is required to slide up and down for a long time due to the sliding connection of the chute board 12 and the chute board 11, heat is generated due to the mutual friction between the chute board 11 and the chute board 12, the chute board 12 is deformed due to the over-high temperature, and the upward and downward movement of the chute board 11 is affected.

As shown in fig. 4, in a specific embodiment, the heat dissipation assembly includes a cooling tube 15, the cooling tube 15 is fixed on the inner side wall of the supporting seat 2, the cooling tube 15 contacts with one side of the sliding groove plate 12, two ends of the cooling tube 15 are respectively connected with a liquid inlet tube 16 and a liquid outlet tube 17, and the cooling tube is respectively located at two sides of the supporting seat 2 and extends out of the supporting seat 2 to be connected with an external pipeline, and the sliding groove plate 12 is cooled by water cooling.
