[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0028] The utility model provides a device for detecting the curvature of a bent heat pipe. A three-jaw chuck is used to clamp the bent heat pipe. A motor drives the bent heat pipe to rotate. A detection mechanism is used to detect the curvature of the bent heat pipe. The screw rod can be rotated to drive the detection mechanism to move and detect different positions of the bent heat pipe. Figures 1-4 , including: a detection bracket 100 and a detection mechanism 200.

[0029] The detection bracket 100 includes a base 110, a motor 120, an output shaft 130, a three-jaw chuck 140, a bracket 150, a screw 160 and a slide 170. The motor 120 is set at the left end of the base 110, the output shaft 130 is set at the output end of the motor 120, and the three-jaw chuck 140 is set at the right end of the output shaft 130. The bracket 150 is set at the top of the base 110, and the screw 160 and the slide 170 are set on the bracket 150.

[0030] The motor 120 drives the three-jaw chuck 140 to rotate via the output shaft 130 , and the three-jaw chuck 140 clamps the bent heat pipe.

[0031] The detection mechanism 200 is arranged on the screw rod 160 and the slide rod 170. The detection mechanism 200 includes a movable frame 210, a sliding frame 220 and a spring 230. The movable frame 210 is arranged on the screw rod 160 and the slide rod 170. The sliding frame 220 is inserted into the top side of the movable frame 210. The spring 230 is connected between the movable frame 210 and the sliding frame 220.

[0032] Among them, the movable frame 210 and the sliding frame 220 are both made of L-shaped plates. The sliding frame 220 is located below the axis of the three-jaw chuck 140. A screw hole 250 connected to the screw rod 160 is opened on the movable frame 210. A sliding hole 260 connected to the slide rod 170 is opened on the movable frame 210. The screw rod 160 is rotated, and the movable frame 210 is driven to move on the slide rod 170 under the action of thread feed. When the bent heat pipe contacts the sliding frame 220, the sliding frame 220 is squeezed. The bending degree of the bent heat pipe is judged according to the movable spacing of the sliding frame 220. The spring 230 supports the sliding frame 220 to rebound.

[0033] Since it is laborious to manually rotate the screw rod 160, a transmission mechanism 300 is connected between the output shaft 130 and the screw rod 160. The transmission mechanism 300 includes a driving pulley 310, a driven pulley 320, and a transmission belt 330. The driving pulley 310 is provided on the output shaft 130, the driven pulley 320 is provided on the screw rod 160, and the transmission belt 330 is connected between the driving pulley 310 and the driven pulley 320.

[0034] When the output shaft 130 rotates, the driving pulley 310 is driven to rotate, and the driving pulley 310 drives the driven pulley 320 to rotate through the transmission belt 330, thereby driving the screw rod 160 to rotate.

[0035] In order to facilitate observation of the sliding distance of the sliding frame 220, a linear scale mark 240 is set on the side of the sliding frame 220. The linear scale mark 240 is a fluorescent mark. The linear scale mark 240 is used to read the moving distance of the sliding frame 220.

[0036] In order to improve the connection stability, the bottom of the base 110 is provided with evenly distributed supporting legs, and the bottom of the supporting legs are provided with anti-skid pads to avoid sliding and improve the placement stability.

[0037] During specific use, the three-jaw chuck 140 clamps the bent heat pipe, and the motor 120 drives the three-jaw chuck 140 to rotate through the output shaft 130. When the bent heat pipe contacts the sliding frame 220, the sliding frame 220 is squeezed, and the bending degree of the bent heat pipe is judged according to the movable spacing of the sliding frame 220. The spring 230 supports the sliding frame 220 to rebound. When the output shaft 130 rotates, it drives the driving pulley 310 to rotate, and the driving pulley 310 drives the driven pulley 320 to rotate through the transmission belt 330, thereby driving the screw 160 to rotate. Under the action of the thread feed, the movable frame 210 is driven to move on the slide rod 170 to detect different positions.

[0038] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
