[0019] To make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below through the drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the present utility model and do not limit the scope of the present utility model. In addition, in the following structures, the description of well-known structures and technologies is omitted to avoid unnecessarily confusing the concept of the present utility model.

[0020] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "top / bottom end", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description. Instead of indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, it should not be construed as a limitation of the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0021] As Figures 1 - 3 shown, a ball screw nut ball return tube hole measuring device includes a base 110, and a fixing tooling 120 is arranged on the base 110. The fixing tooling 120 is a fixing support member as Figure 3 shown.

[0022] The upper part of the fixed support is provided with a V-shaped support groove 121. A convex section 122 is arranged in the middle of the V-shaped support groove 121. The convex section 122 divides the horizontal bottom surface of the V-shaped support groove 121 into two parts. The V-shaped support groove 121 includes a horizontal bottom surface at the bottom, and a first support inclined surface and a second support inclined surface are respectively arranged on both sides of the horizontal bottom surface.

[0023] The fixed support is designed by profiling. Through the design of the V-shaped support groove 121 and the convex section 122, the contact area between the workpiece and the tooling is increased, ensuring a high degree of fit between the workpiece and the positioning device, thereby ensuring the accuracy of the measurement of the nut workpiece.

[0024] A support frame 130 is arranged on one side of the base 110. A measuring gauge 140 is arranged on the support frame 130. The head 141 of the measuring gauge 140 is aligned with the return ball tube hole 201 of the ball screw nut 200 arranged on the fixed support.

[0025] The support frame 130 includes a support vertical rod 131. A slider assembly 132 is arranged on the support vertical rod 131. The head 141 of the measuring gauge 140 is supported by a support cross bar 133 arranged on the slider assembly 132.

[0026] A locking member 134 is arranged on the slider assembly 132. When the slider assembly 132 moves along the support vertical rod 131, the locking member 134 is loosened. After the slider assembly 132 moves into place, the locking member 134 is locked to fix the relative position between the slider assembly 132 and the support vertical rod 131.

[0027] A head mounting seat 135 is arranged at the end of the support cross bar 133. The head 141 of the measuring gauge 140 is mounted through the head mounting seat 135.

[0028] Due to the above structure, the working principle of the present utility model is as follows:

[0029] 1. Place the base 110 on the table, and then install the slider assembly 132 and the measuring gauge 140;

[0030] 2. The contact surface between the fixed tooling 120 and the workpiece is designed by profiling. Through the design of the V-shaped support groove 121 and the convex section 122, the contact area between the workpiece and the tooling is increased, ensuring a high degree of fit between the workpiece and the positioning device, thereby ensuring the accuracy of the measurement of the nut workpiece.

[0031] 3. The measuring gauge 140 can quickly obtain whether the product size meets the technical requirements by measuring the distance between the fixed dimension (such as a straight groove) of the workpiece and the bottom step of the return ball tube hole, ensuring the product quality.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model.

[0033] Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments. What is described in the above-mentioned embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
