Description

Technical Field

[0001] This utility model relates to the field of mechanical measurement technology, and in particular to a distance measuring mechanism for a camshaft groove. Background Technology

[0002] The cam-driven pitch control module rotates the camshaft, causing the camshaft grooves on the camshaft to rotate synchronously. This, in turn, pushes the slider to move along a specific trajectory of the camshaft grooves, thus achieving pitch control. By customizing the camshaft grooves, the rotational speed and direction of the camshaft, the position, speed and acceleration of the slider can be precisely controlled. The spacing of the camshaft grooves requires extremely high precision.

[0003] There are few existing camshaft groove measuring mechanisms on the market, and most of them can only measure camshafts that are stationary on the adjustment mechanism. The measurement can only measure the distance between adjacent camshaft grooves on a single surface of the camshaft and the width of the camshaft groove.

[0004] For the reasons mentioned above, it is necessary to improve the existing technology. Utility Model Content

Detailed Implementation

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0022] Please see Figure 1-6 This utility model provides a camshaft groove ranging mechanism, including a base 1; Adjustment component 2 includes a movable plate 20 movably mounted on the base 1, a V-shaped frame 21 fixedly mounted on the movable plate 20, rollers 22 rotatably mounted on the upper surfaces of both sides of the V-shaped frame 21, and a first drive motor for driving the rollers 22 to rotate. The adjustment component 2 is provided in two sets, which are respectively used to place the two ends of the camshaft. The gap between the rollers 22 is smaller than the width of the end of the camshaft being measured. Measuring component 3 is movably mounted on the base 1 and driven by a driving device 31 to move laterally along the base 1. Measuring component 3 is used to measure the distance between adjacent camshaft grooves and the width of the camshaft grooves.

[0023] In the above structure, the user manually moves the adjustment components. After the two adjustment components are driven by the user to move to the designated position on the base, the two ends of the camshaft are placed between the rollers on the adjustment components. The gap between the rollers is smaller than the width of the camshaft ends, so that the camshaft is lifted by the rollers. When the measuring component measures the camshaft, the rollers rotate, causing the camshaft to rotate synchronously, so that the measuring component can measure the surface around the camshaft. At the same time, the driving device drives the measuring component to move on the base, so that the measuring device moves along the camshaft axis, thereby accurately measuring the distance between adjacent camshaft grooves and the width of the camshaft groove.

[0024] Specifically, a first guide rail 100 is fixedly installed on the base 1, and a first slider 101 that cooperates with the first guide rail 100 is fixedly installed on the bottom surface of the moving plate 20. The cooperation between the first slider and the first guide rail makes the moving distance of the moving plate more accurate and reduces the coefficient of friction when the moving plate moves, thereby reducing the vibration during the moving process.

[0025] Specifically, the first guide rail 100 has two parallel rails. The two parallel first guide rails can guide the moving plate and evenly bear the pressure applied by the moving plate to the first guide rails.

[0026] Specifically, the measuring component 3 includes an ascending frame 30 mounted on the base 1, a third guide rail 32 mounted on one side of the ascending frame 30, a third slider 33 movably mounted on the third guide rail 32, a height adjustment plate 34 fixedly mounted on the upper surface of the third slider 33, a lead screw 35 mounted on the ascending frame 30, a distance measuring camera 36 fixedly mounted on the top of the height adjustment plate 34, and a light source device 37 for illuminating the distance measuring camera 36. The lead screw 35 drives the height adjustment plate 34 to move on the third guide rail 32, and the distance measuring camera 36 is horizontally mounted on the top of the camshaft. During use, the user can drive the height adjustment plate through the lead screw, causing the third slider to move up and down along the third guide rail, thereby moving the height adjustment plate to a set position. Then, the distance measuring camera horizontally mounted on the top of the camshaft measures the camshaft. When the indoor lighting is dim, the light source device can illuminate the camshaft, enabling the distance measuring camera to clearly measure the required parameters on the camshaft.

[0027] Specifically, a magnetic scale 10 is fixedly installed on one side of the base 1, and a magnetic head 300 that works in conjunction with the magnetic scale 10 is fixedly installed on the heightening frame 30. The magnetic scale and the magnetic head adopt a quasi-contact working mode, and the gap between them is less than or equal to 0.01mm, so that there is less air between them, which avoids the air magnetic resistance in the air from causing the signal output obtained by the magnetoelectric conversion between the magnetic scale and the magnetic head to be more stable.

[0028] Specifically, a second guide rail 110 is fixedly installed on the base 1, and a second slider 111 that works in conjunction with the second guide rail 110 is fixedly installed at the bottom of the riser 30. The cooperation of the second slider and the second guide rail makes the movement distance of the riser more precise and reduces the coefficient of friction when the riser moves, thereby reducing the vibration during the movement of the riser.

[0029] Specifically, the top end of the lead screw 35 is provided with a handle 350 for rotating the lead screw 35. The handle makes it easier for the user to rotate the lead screw and also allows for better control of the rotation distance of the lead screw.

[0030] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
