[0045] refer to Figs. 1-2 At least one embodiment provides a cemented carbide ball tooth surface quality measuring device, comprising: a placement mechanism 1, which includes a placement block 11 for placing the ball tooth and a power member 14 for rotating the placement block 11, wherein the ball tooth is placed on the placement block 11, and the power member 14 is adapted to drive the placement block 11 and the ball tooth to rotate; and multiple limit detection mechanisms 2, which include limit detection elements 22 that directly abut against the ball tooth and a module 21 for driving the limit detection elements 22 to move vertically, so as to drive the limit detection elements 22 to position and detect the surface quality of the ball tooth. In this process, the multiple limit detection elements 22 press against the ball tooth from multiple directions, thereby positioning the ball tooth to the center of the placement block 11, and then the module... Group 21 drives multiple limit detection elements 22 to move vertically, and power element 14 drives the ball teeth on the placement block 11 to rotate, so that the multiple limit detection elements 22 contact different positions on the ball teeth. By detecting the pressure change through the limit detection elements 22 and comparing it with the set value, the surface quality of the ball teeth can be obtained; base 3; wherein the limit detection element 22 includes a limit element 25 that directly abuts the ball teeth and a sensor 23 that detects the pressure change of the limit element 25. The pressure change detected by the sensor 23 is consistent with the surface shape change of the ball teeth; the power element 14 and the sensor 23 are electrically connected to an external control system for controlling the operation and stop of the components and transmitting signals.
[0046] In some embodiments, the rotation shaft of the power component 14 passes through the base 3 and is connected to the placement block 11, thereby driving the placement block 11 to rotate relative to the base 3; the limiting detection mechanism 2 is symmetrical about the placement block 11, thereby ensuring that the ball teeth are subjected to uniform force; the limiting detection component 22 also includes a mounting plate 24 for mounting the sensor 23; the limiting component 25 is inserted and connected to the mounting plate 24 through a guide shaft, thereby ensuring that the movement path of the limiting component 25 is accurate.
[0047] In some embodiments, the housing of the power component 14 is fixedly connected to the base 3; the sensor 23 is a pressure sensor used to contact the surface of the ball tooth, and to determine the change in the shape of the ball tooth surface based on the change in pressure on the ball tooth surface; the mounting plate 24 is disposed on the moving part of the module 21 and is used to drive the mounting plate 24 to move.
[0048] In some embodiments, the power component 14 is a stepper motor for precise control of the rotation angle; the center of the placement block 11 is connected to the rotation axis of the power component 14 to ensure good rotational stability of the placement block 11; the limiting component 25 includes a first plate 26, a second plate 27, an elastic element 28, and an abutment rod 29; the abutment rod 29 is disposed on the surface of the second plate 27 facing the placement block 11, the second plate 27 is connected to the first plate 26 through the elastic element 28 and the guide shaft, for compressing the elastic element 28 after the abutment rod 29 contacts the ball tooth, ensuring that the multiple limiting components 25 cooperate to limit the ball tooth, so that it is located in the middle of the placement block 11, and when the abutment rod 29 moves on the surface of the ball tooth, force is applied to the abutment rod 29 to keep it in contact with the ball tooth, and to buffer the pressure on the sensor 23, the guide shaft passes through the first plate 26 and the mounting plate 24.
[0049] In some embodiments, the first plate 26 is adapted to press the sensor 23 to transmit the pressure of the ball teeth against the abutment rod 29 to the sensor 23; the elastic element 28 is located between two guide shafts; the end of the abutment rod 29 facing the placement block 11 is smaller than the end that contacts the second plate 27, in order to reduce the contact area with the ball teeth.
[0050] In some embodiments, the first plate 26, the second plate 27, and the mounting plate 24 are parallel plates; the elastic element 28 is a spring; and the end of the abutment rod 29 facing the placement block 11 is provided with a rounded corner to avoid damaging the ball teeth.
[0051] In some embodiments, the placement block 11 is provided with a central hole 12 and an air pipe connector 13; the central hole 12 and the air pipe connector 13 are connected and serve as a gas channel, and the external control system draws air through the central hole 12 and the air pipe connector 13 to fix the ball teeth in the middle of the placement block 11; the central hole 12 penetrates the surface of the placement block 11 away from the power component 14, and this surface is the surface where the ball teeth are placed.
[0052] In some embodiments, the tracheal connector 13 is located on the side of the placement block 11; the central hole 12 is concentric with the rotation axis of the power component 14.
[0053] Working principle: Before using a cemented carbide ball tooth surface measurement device, the air pipe connector 13 is electrically connected to the external control system. Then, the operator moves the ball tooth to the center of the placement block 11. During this process, the ball tooth pushes multiple abutment rods 29 away. Then, the external control system draws air through the air pipe connector 13 and the center hole 12, positioning the ball tooth in the center of the placement block 11. When using the cemented carbide ball tooth surface measurement device: under the control of the external control system, the power component 14 drives the placement block 11 to rotate at a uniform speed, while the module 21 drives the limit detection component 22 vertically. The ball moves in a straight direction. During this process, the abutment rod 29 contacts different positions on the surface of the ball tooth. At the same time, the abutment rod 29 applies pressure to the sensor 23 through the first plate 26 and the second plate 27. The sensor 23 transmits the pressure signal change to the external control system. The external control system can determine the shape change of the ball tooth based on the transmitted pressure signal change. The external control system can determine whether the surface finish of the ball tooth is qualified based on the received pressure signal change value and the specified pressure signal change value. After the test is completed, the operator removes the ball tooth and places a new ball tooth, repeating the above process until the work is finished.
