Method and system for testing weight balance of racket and ball arm

Abstract

The invention discloses a method and a system for testing the weight balance of a racket and a ball arm. The system comprises a test platform and an upper control host, wherein the test platform has a box body structure; the top of the box body is provided with a horizontal mounting surface; the horizontal mounting surface is provided with at least one head contact base and one tail contact base;the positions at which the head contact base and the tail contact base are arranged are opposite, and the top end faces of the head contact base and the tail contact base are positioned on the same horizontal plane; the bottom parts of the head contact base and the tail contact base are connected with pressure sensors; a control chip is arranged inside the test platform; and the control chip processes signals transmitted by the pressure sensors and outputs related data to the upper control host. The system has a compact structure, is convenient to use and has high automation degree. The weight and the balance points of objects to be tested can be acquired after the objects to be tested are arranged as required during operation, the weight distribution of measured parts can be displayed, the measurement speed is high, and the method and the system are suitable for testing mass products.

Description

technical field [0001] The invention relates to the technical field of appliance testing, in particular to a method for testing the weight balance of rackets and clubs, and a system for testing the weight balance. Background technique [0002] In the racket club manufacturing industry, the weight and balance of the racket are manually detected by a common balance board through a scale and a common electronic scale. For example, the Chinese patent No. ZL 200920036273.6 "Detection device for center of gravity position of racket club" (for specific structure, see figure 1 ), the device includes a detection platform, a scale, and a support shaft. The support shaft parallel to the detection platform is installed above the detection platform. A scale is installed on the detection platform. The length direction of the scale is perpendicular to the support shaft. In the horizontal state, the racket shaft is placed on the support shaft, the shaft of the racket shaft is perpendicular...

For example, the Chinese patent No. ZL 200920036273.6 "Detection device for center of gravity position of racket club" (for specific structure, see figure 1 ), the device includes a detection platform, a scale, and a support shaft. The support shaft parallel to the detection platform is installed above the detection platform. A scale is installed on the detection platform. The length direction of the scale is perpendicular to the support shaft. In the horizontal state, the racket shaft is placed on the support shaft, the shaft of the racket shaft is perpendicular to the support shaft, and then the contact point between the racket shaft and the support shaft is adjusted so that the racket shaft is in a horizontal balance state. At this time, the racket ball The point of contact between the rod and the support shaft is the center of gravity of the racket shaft, then look down on the testing platform, make the line of sight vertical to the scale, and read the scale on the scale corresponding to the bottom end of the handle of the racket shaft, and you can get the racket ball. From the above description, it can be seen that the position of the center of gravity of the rod to the bottom of the handle, this kind of device needs to manually adjust the position of the racket to maintain the relative balance position of the racket, and then read the balance point of the racket through the scale , at the same time, since the balance point is measured manually with a visual scale, it is greatly affected by subjective factors, and has the disadvantages of large errors and relatively long time-consuming. In fact, the value of the balance point measured by each measurer is There is a certain deviation, which directly affects the quality of the produced racket cue
