Detailed Implementation

[0024] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0025] like Figure 1 , 2 As shown, a ball nut measuring device includes a base 101. A placement plate 102 is arranged on the base 101 in a left-right direction. Multiple insertion rods 103 for inserting and fixing ball nuts are respectively arranged on the front side of the placement plate 102 in a left-right direction. A U-shaped mounting bracket 104 spanning the placement plate 102 in a left-right direction is also provided on the base 101. A measuring module is arranged on the mounting bracket 104. A placement groove 105 is slidably arranged on the base 101, containing a good product groove 106 and a defective product groove 107. A first telescopic push rod 108 adapted to the multiple insertion rods 103 is provided on the placement plate 102. A pusher plate 109 is provided on the first telescopic push rod 108. A first engaging groove 112 engaging with the good product groove 106 and a second engaging groove 113 engaging with the defective product groove 107 are provided in the placement groove 105.

[0026] like Figure 1 , 3 As shown, the measurement module includes a mounting plate 201 that slides on the top of the mounting frame 104 in the left-right direction. A second telescopic push rod 202 of the measurement module is vertically mounted on the mounting plate 201. A U-shaped fixing frame 203 is provided at the lower end of the output shaft of the second telescopic push rod 202. Laser rangefinders 204 are respectively provided at both ends of the fixing frame 203.

[0027] The ball nut to be tested is inserted into the plug rod 103, thus initially fixing it on the placement plate 102; then the rear end of the ball nut is made to abut against the push plate 109 to achieve the positioning of the ball nut, avoiding the impact of the convenience and accuracy of measurement due to the positional displacement of the ball nut in the front-back direction.

[0028] The drive mounting plate 201 moves left and right, adjusting the fixing frame 203 and the laser rangefinder 204 to be directly above the ball nut. At the same time, the second telescopic push rod 202 extends downward by a certain length, fitting the fixing frame 203 and the laser rangefinders 204 on both sides of the ball nut respectively, preparing for measurement.

[0029] The laser rangefinder 204 is activated, measuring the distances between itself and both sides of the ball nut. The outer diameter of the ball nut can be calculated by subtracting the measured distances between each laser rangefinder 204 and the ball nut from the fixed distance between the two laser rangefinders 204.

[0030] The measurement results are automatically analyzed by the system to determine whether the ball nut meets the quality standards. If it is qualified, the placement slot 105 is moved so that the good product slot 106 is matched with the position of the plug rod 103. Only when the output shaft of the first telescopic push rod 108 extends a certain length can the pusher plate 109 be pushed to move the ball nut into the good product slot 106 in the placement slot 105. If it is not qualified, the defective product slot 107 is moved to a position that matches the plug rod 103, and the ball nut is pushed into the defective product slot 107 by the first telescopic push rod 108 and the pusher plate 109.

[0031] After completing one measurement, the device resets and begins the next round of ball nut measurement. This ball nut measuring device significantly improves inspection efficiency and accuracy through automated positioning, measurement, and classification functions, while reducing manual intervention, making it suitable for quality control needs in mass production environments.

[0032] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, a first linear slide 110 is provided on the base 101 along the front-back direction, located at the side end of the placement slot 105. A connecting plate 111 connected to the placement slot 105 is provided on the slide of the first linear slide 110. The push plate 109 is U-shaped, and both ends of the push plate 109 are sleeved on the plug-in rod 103. The front-back movement of the slide of the first linear slide 110 can drive the placement slot 105 to move, ensuring that the good product slot 106 or the defective product slot 107 is always directly below the push plate 109, so as to complete the classification and storage.

[0033] According to another embodiment of the present invention, such as Figure 1 As shown, the top of the mounting bracket 104 has a through hole 205 that fits onto the outside of the fixed end of the second telescopic push rod. The top of the mounting bracket 104 also has a second linear slide 206 located on one side of the through hole 205 along the left-right direction.
