Description

Technical Field

[0001] This invention relates to the field of measuring equipment technology, and in particular to a self-aligning roller rotating inner diameter micrometer. Background Technology

[0002] Traditional methods require frequent handheld measurements, necessitating keeping the measuring rod horizontal and constantly adjusting the measuring head to find the concentric point. Measuring a single point on average takes over 180 seconds, and the same method requires measuring at least four points in a circle. Furthermore, all measurements must be repeated if there are sudden changes in data or measurement errors, resulting in an overall work time of approximately 4 hours. Traditional manual measurement is prone to uneven force, arm tremors, inaccurate point finding, and misalignment of the axes, affecting measurement accuracy. Additionally, during rotational measurements, the lack of dynamic balance leads to reference shifts, affecting the consistency of continuous measurement data. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art.

[0004] To achieve the above objectives, the present invention proposes a self-aligning roller rotating inner diameter micrometer, comprising a fixing component, a rotating component, and a measuring component;

[0005] The fixing component includes a chuck seat, which includes an inner ring and an outer ring arranged concentrically. A plurality of clamping sliders are movably provided between the inner ring and the outer ring. A movement control component for controlling the clamping sliders is provided between the inner ring and the outer ring. The rotating component is disposed above the fixed component, and the rotating component includes a bearing seat fixedly connected to the chuck seat, and a shaft ring is rolledly connected to the bearing seat; The measuring component includes a compensation slider fixedly connected to the shaft ring. A measuring rod is slidably mounted through the compensation slider. The length of the measuring rod is arranged in the same direction as the radius of the inner ring. A probe assembly is provided at one end of the measuring rod facing the center of the inner ring, and a dial indicator is provided at the other end of the measuring rod away from the probe assembly.

[0006] This invention uses a fixed component to hold the chuck seat in place at the position to be measured. Then, by rotating the shaft of the rotating component, the measuring component is driven to rotate. When the measuring component rotates to the position to be measured, the probe assembly can press against the surface of the component to be measured, thereby completing the measurement operation of the component. This avoids the errors caused by traditional manual measurement and the fatigue caused to the operator by high-frequency measurement.

[0007] Optionally, the probe assembly includes a detection head disposed at the top of the measuring rod, and a retainer is fixedly provided on the outer wall of the portion of the measuring rod located between the detection head and the compensation slider. A spring is fixedly provided on one end of the retainer facing the compensation slider, the spring is sleeved on the outside of the measuring rod, and the other end of the spring abuts against the compensation slider.

[0008] Furthermore, the end of the detection head is provided with a hemispherical contact head.

[0009] Furthermore, the compensation slider is provided with a through hole that is slidably connected to the measuring rod, and a plurality of balls that are tactilely connected to the measuring rod are provided in the through hole, and the balls are evenly distributed on the periphery of the measuring rod.

[0010] Furthermore, the motion control component includes a turntable, which is rotatably connected to both the inner ring and the outer ring. A plurality of drive rods are rotatably connected between the inner ring and the outer ring. Each drive rod can be externally connected to a drive power component for controlling the rotation of the drive rod. The drive rod is provided with a drive gear, and the turntable is provided with turntable push teeth that mesh with the drive gear. The turntable is provided with a spiral guide rail on the side opposite to the turntable push teeth, and the clamping slider is provided with a sliding groove that is slidably connected to the spiral guide rail.

[0011] Furthermore, the drive rod has a rotating interface at one end through the outer ring for controlling the rotation of the drive rod, and the rotating interface is used to connect the drive power component.

[0012] Furthermore, the clamping slider includes a slider body with a groove and a damping block. The moving direction of the slider body is the same as the radial direction of the inner ring, and the damping block is located at the end of the slider body facing the center of the inner ring. The damping block and the slider are fixedly connected by bolts.

[0013] Furthermore, a guide rod is provided between the inner rings along the radial direction of the inner rings, and a guide groove is provided on the slider body to cooperate with the guide rod.

[0014] Furthermore, the bearing housing is provided with a bearing and a bushing, and the bearing and bushing are inclined at 6° so that the shaft ring can be rotated and centered during horizontal rotation.

[0015] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0018] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0019] This invention provides a self-aligning roller rotating inner diameter micrometer, as described below. Figures 1 to 7 Please provide a detailed explanation.

[0020] A self-aligning roller rotating inner diameter micrometer includes a fixed component 1, a rotating component 2, and a measuring component 3; The fixing component 1 includes a chuck seat 11, which includes an inner ring 111 and an outer ring 112 arranged concentrically. The bottom edges of the inner ring 111 and the outer ring 112 are integrally connected to a bottom shell 113. A plurality of clamping sliders 12 are movably provided between the inner ring 111 and the outer ring 112. A movement control component 13 for controlling the clamping of the clamping sliders 12 is provided between the inner ring 111 and the outer ring 112. The rotating component 2 is disposed above the fixed component 1, and the rotating component 2 includes a bearing seat 21 fixedly connected to the chuck seat 11, and a shaft ring 22 is rolledly connected to the bearing seat 21, and the shaft ring 22 can rotate 360°. The measuring component 3 includes a compensation slider 31 fixedly connected to the shaft ring 22. In one embodiment, the compensation slider 31 is set as an SCS intelligent compensation slider 31, that is, an SCS linear slider. The compensation slider 31 is fixed to the upper surface of the shaft ring 22 by four bolts. The compensation slider 31 can rotate 360° with the shaft ring 22. A measuring rod 32 is slidably provided through the compensation slider 31. The length of the measuring rod 32 is arranged in the same direction as the radius of the inner ring 111. A probe assembly 33 is provided at one end of the measuring rod 32 facing the center of the inner ring 111. A dial indicator 34 is provided at the other end of the measuring rod 32 away from the probe assembly 33. The probe of the dial indicator 34 is set facing away from the center of the inner ring 111.

[0021] This invention uses a fixed component 1 to hold the chuck seat 11 in place at the position to be measured. Then, by rotating the shaft ring 22 of the rotating component 2, the measuring component 3 is driven to rotate. When the measuring component 3 rotates to the position to be measured, the probe assembly 33 can press against the surface of the component to be measured, thereby completing the measurement operation of the component to be measured. This avoids the errors caused by traditional manual measurement and the fatigue caused to the operator by high-frequency measurement.

[0022] In some embodiments, the probe assembly 33 includes a detection head 331 disposed at the top of the measuring rod 32. A retainer 332 is fixedly disposed on the outer wall of the portion of the measuring rod 32 located between the detection head 331 and the compensation slider 31. A spring 333 is fixedly disposed on one end of the retainer 332 facing the compensation slider 31. The spring 333 is sleeved on the outside of the measuring rod 32, and the other end of the spring 333 abuts against the compensation slider 31. When the retainer 11 is engaged with the workpiece to be measured, the measuring rod 32 moves toward the side away from the center of the inner ring 111 (i.e., the workpiece to be measured). At this time, the retainer 332 can compress the spring 333, allowing the spring 333 to store elastic potential energy. The spring 333 will then push the retainer 332 toward the center of the inner ring 111, that is, give the measuring rod 32 a thrust toward the center of the inner ring 111. This thrust can cause the end of the measuring rod 32 to abut against the surface of the workpiece to be measured, thereby ensuring that the detection head 331 of the measuring rod 32 is always in contact with the workpiece to be measured during the measurement process.

[0023] In some embodiments, the end of the detection head 331 is provided with a hemispherical contact head. The hemispherical contact head ensures that the center of the end of the detection head 331 is always in contact with the measured point of the structure to be measured, thereby avoiding measurement inaccuracies caused by other parts of the detection head 331 contacting the measured point.

[0024] In some embodiments, the compensation slider 31 is provided with a through hole 311 that is slidably connected to the measuring rod 32. A plurality of balls 312 that are rollably connected to the measuring rod 32 are provided within the through hole 311, and the balls 312 are evenly distributed around the periphery of the measuring rod 32. The arrangement of the balls 312 can effectively reduce the friction between the compensation slider 31 and the measuring rod 32, ensuring smooth movement of the measuring rod 32 and reducing wear caused by movement.

[0025] In some embodiments, the motion control component 13 includes a turntable 131, which is rotatably connected to both the inner ring 111 and the outer ring 112. A plurality of drive rods 132 are rotatably connected between the inner ring 111 and the outer ring 112. Each drive rod 132 can be externally connected to a drive power component for controlling the rotation of the drive rod 132. A drive gear 133 is provided on the drive rod 132, and a turntable 131 push tooth is provided on the turntable 131 that meshes with the drive gear 133. A spiral guide rail 135 is provided on the side of the turntable 131 away from the pusher teeth of the turntable 131, and a groove 121 is provided on the clamping slider 12 to slide and connect with the spiral guide rail 135.

[0026] When it is necessary to clamp the test component, the operator connects the drive power component to the drive rod 132. The drive power component drives the drive rod 132 to rotate. The drive gear 133 on the drive rod 132 meshes with the push gear of the turntable 131 and rotates, causing the turntable 131 to rotate around the inner ring 111. At this time, due to the rotation of the turntable 131, the spiral guide rail 135 on the turntable 131 and the slide groove 121 produce sliding movement. Under the push of the spiral guide rail 135, the clamping slider 12 will move along the radial direction of the inner ring 111. In one embodiment, the inner ring 111 is provided with a guide channel for the clamping slider 12 to pass through. The guide channel ensures that the clamping slider 12 has only the degree of freedom to translate along the radial direction of the inner ring 111.

[0027] In some embodiments, the drive rod 132 has a rotary interface 14 at one end through the outer ring 112 for controlling the rotation of the drive rod 132. The rotary interface 14 is used to connect a drive power component. The drive power component can be a hand crank, a motor, or other components that can control the rotation of the drive rod 132.

[0028] In some embodiments, the clamping slider 12 includes a slider body 122 with a groove 121 and a damping block 123. The sliding direction of the slider body 122 is the same as the radial direction of the inner ring 111, and the damping block 123 is disposed at the end of the slider body 122 facing the center of the inner ring 111. The damping block 123 and the slider are fixedly connected by bolts. The separate arrangement of the slider body 122 and the damping block has two advantages. First, by adding the damping block 123, the friction between the damping block 123 and the tested component can be increased, thereby achieving a better clamping and fixing purpose. Second, since the clamping process with the tested component will generate wear, the long-term accumulation of wear will lead to severe wear at the contact part between the clamping slider 12 and the tested component. The separate arrangement allows only the damping block 123 to be replaced when it is severely worn, reducing the material waste caused by replacing the slider body 122 at the same time.

[0029] In some embodiments, a guide rod 15 is provided between the inner rings 111 along the radial direction of the inner rings 111, and a guide groove 124 is provided on the slider body 122 to cooperate with the guide rod 15. In a specific embodiment, a moving groove 4 for moving the clamping slider 12 is provided on the bottom shell 113, the guide rod 15 is disposed in the moving groove 4, and the two ends of the guide rod 15 are fixedly connected to the inner ring 111 and the outer ring 112 respectively. The arrangement of the guide groove 124 and the guide rod 15 can ensure that the clamping slider 12 moves along the radial direction of the inner ring 111, and restrict the degree of freedom of the clamping slider 12 to only the degree of freedom of translation along the radial direction of the inner ring 111.

[0030] In some embodiments, the bearing housing 21 is provided with a bearing 211 and a bushing 212 inside, and the bearing 211 and the bushing 212 are inclined at 6° so that the shaft ring 22 can be rotated and centered during horizontal rotation.
