Embodiment Construction
[0020] Such as figure 1 As shown in the figure, a heating furnace for thin-walled cylindrical workpiece shrink fit, the inner wall of the heating furnace 1 is installed with a high-precision laser displacement sensor 3, the laser displacement sensor 3 is installed and fixed on the support 4, and the support 4 is fixed on the ground pillar, and the incident light 3g and The observation window 7 is vertical, and a gap is reserved between the laser displacement sensor 3 and the observation window 7 near the inner side wall of the heating furnace 1, such as figure 2 As shown, the positions of the four laser displacement sensors 3 are evenly distributed in the circumferential direction of the heating furnace.
[0021] Such as figure 1 As shown, the distance between the laser displacement sensor 3 and the observation window 7 close to the inner wall of the heating furnace 1 is 1 mm to 2 mm, and the adjusting screw 6 and the inner threaded sleeve 5 are evenly distributed around t...

The invention relates to a heating furnace for hot sleeving of a thin-wall cylindrical workpiece. The heating furnace is characterized in that high-precision laser displacement sensors 3 are mounted on the inner side wall of the heating furnace 1; the laser displacement sensors 3 are mounted and fixed to brackets 4; the brackets 4 are fixed to ground struts; incident light 3g is perpendicular to an observation window 7; a clearance is maintained between the laser displacement sensor 3 and the side, close to the inner side wall of the heating furnace 1, of the observation window 7; and the four laser displacement sensor 3 are uniformly distributed in the circumferential direction of the heating furnace. According to the heating furnace, position change of a hot sleeving workpiece 10 in the heating furnace 1 can be accurately measured through the laser displacement sensor 3 mounted outside the heating furnace 1, position of the hot sleeving workpiece 10 can be adjusted while heating, hot sleeving operation can be quickly achieved after a heating furnace cover 2 is opened, temperature of the thin-wall cylindrical workpiece is prevented from decreasing, and success rate of hot sleeving is greatly increased.
Description
technical field [0001] The invention relates to a heating furnace for shrink-fitting thin-walled cylindrical workpieces Background technique [0002] Shrink fitting processing of large thin-walled cylindrical workpieces is a relatively common process method, which is widely used in the manufacturing process of various fields. The shrink fitting of small-sized and thick-walled workpieces is relatively simple, and the shrink-fitting of large-sized thin-walled cylindrical workpieces, Due to the fast heat dissipation of thin-walled workpieces, the method of thermal fitting in the heating furnace is usually adopted. Since the positioning of thin-walled parts in the heating furnace is relatively difficult, if the thermal fitting operation is not completed in a short time after opening the furnace cover, it will still cause The temperature of the workpiece decreases, which leads to the failure of the heat sleeve; another method is to use the medium frequency induction heating metho...
