Problems solved by technology

[0005] However, in the above measurement process, when the two spheres of the bat are placed on any two supporting seats, the club will be deformed due to the action of the club's own gravity, which will seriously affect the measurement of the ball center distance. Accuracy, thus affecting the calibration results of the CMM

Embodiment Construction

[0021] In order to make the technical means, creative features, goals and effects of the present invention easy to understand, the following embodiments will specifically illustrate the ball center distance detection device and its detection method of the present invention in conjunction with the accompanying drawings.

[0022] figure 1 It is a structural schematic diagram of the ball center distance detection device in the embodiment of the present invention.

[0023] Such as figure 1 As shown, in this embodiment, the ball center distance detection device 100 performs non-contact measurement of the ball center distance of the bat 200 as a standard, and in this embodiment, it can measure the ball center distance of the bat within the length range of 300 mm to 1000 mm. to test. The bat 200 includes: two balls 201 and a club 202 , the club 202 connects the two balls 201 . In this embodiment, a 300mm bat purchased from Germany is used as the bat. The values ​​given by the Germ...

Abstract

The invention provides a bat ball center distance detection device and a detection method thereof. The bat ball center distance detection device comprises a base body, a fixed supporting portion, two mobile supporting portions, two measuring portions and a calculating portion, wherein the base body comprises a guide rail and two brackets which are fixed at two ends of the guide rail respectively; the fixed supporting portion is fixed on the guide rail and used for supporting balls; the two mobile supporting portions are respectively arranged at two sides of the fixed supporting portion, each mobile supporting portion comprises a ball side supporting unit which is movably installed on the guide rail and used for supporting the ball and a bat side supporting unit which is movably installed on the guide rail, arranged between the fixed supporting portion and the ball side supporting unit and used for supporting a ball rod; the two measuring portions are in one-to-one correspondence with the two ball side supporting units, are installed on the two brackets respectively, respectively measure a first distance which one of the ball side supporting unit moves and a second distance which the other ball side supporting unit moves based on predetermined measurement rules; and the calculating portion calculates the ball center distance according to the first distance and the second distance.

Description

technical field [0001] The invention relates to a ball center distance detection device capable of accurately detecting the ball center distance of a bat. Background technique [0002] The three-coordinate measuring instrument is used in the field of measurement. It can measure the size, angle and spatial position of the contour and surface of the product, and can effectively measure products with curved surfaces. The three-coordinate measuring instrument has an irreplaceable role in the field of measurement. . [0003] The measurement accuracy of the three-coordinate measuring instrument is often checked with a ball stick. The bat consists of balls arranged at both ends and a club connecting the two balls. First, fit the center of the ball by measuring multiple points on the sphere, then measure the distance between the two spheres, and finally get the center distance of the bat, according to the measured center distance and the known center distance of the bat By compar...
