Description

Technical Field

[0001] This application belongs to the field of measuring device technology, specifically relating to a target ball measuring fixture. Background Technology

[0002] The basic working principle of a laser tracking measurement system is to place a reflector at the target point. The laser emitted by the tracking head hits the reflector and returns to the tracking head, thus determining the spatial coordinates of the target point. When the target moves, the tracking head needs to adjust the beam direction to align with the target. The returned beam is received by the detection system and used to calculate the target's spatial position. Currently, laser tracking devices are often used as the tracking head, and a target sphere as the reflector. Due to limitations imposed by the target sphere's structure and the height differences between devices within the factory area, and to prevent the target sphere from being obstructed by railings, pipes, or other structures within the factory area, the position of the target sphere needs to be precisely adjusted. However, existing target sphere measurement fixtures cannot meet these requirements, resulting in lower measurement accuracy. Summary of the Invention

[0003] To address the technical problem of low measurement accuracy when current target ball measuring fixtures are applied to measurement operations in factory areas with height differences, this application provides a target ball measuring fixture.

[0004] In a first aspect of this application, a target ball measuring fixture is provided, comprising: A base, the bottom surface of which has a concave arc surface, and the bottom surface of which is operably magnetic; A column is installed at the top of the base; The adjustment component is operablely slidable or fixedly mounted on the column; A lifting rod is disposed on the adjustment assembly, and the angle between the lifting rod and the column is operablely adjustable; the lifting rod is operablely rotatable about the axis of the column. A target ball seat is disposed at one end of the lifting rod, and the distance between the target ball seat and the adjusting component is operablely adjustable so that the target ball seat can move closer to or further away from the column, and that the target ball seat can rotate around the column.

[0005] In some embodiments, an arc-shaped plate is provided at the bottom end of the seat, the bottom surface area of ​​the arc-shaped plate is larger than the arc surface area of ​​the bottom surface of the seat, and the arc-shaped plate is also magnetic when the bottom surface of the seat is magnetic.

[0006] In some embodiments, the curved plate is flexible.

[0007] In some embodiments, the thickness of the arc-shaped plate gradually decreases from the center to both sides along the arc direction.

[0008] In some embodiments, the arc-shaped plate is detachably disposed on the bottom surface of the base.

[0009] In some embodiments, the bottom surface of the base is provided with a snap-fit ​​groove, and the arc-shaped plate is provided with snap-fit ​​posts along its length direction, the snap-fit ​​posts being slidably connected to the snap-fit ​​groove.

[0010] In some embodiments, the base is a magnetic base.

[0011] In some embodiments, the adjustment component includes: The first adjusting seat has a hoop and clamping arms disposed on both sides of the hoop, and both clamping arms are provided with a first through hole; A locking component, wherein one end of the locking component is provided with a first connecting part and the other end of the locking component is provided with a handle; The second adjusting seat has a second through hole at one end, which is sleeved on the lifting rod. The other end of the second adjusting seat has a second connecting part. The first connecting part passes through at least one first through hole and connects with the second connecting part so that the hoop tightens the column.

[0012] In some embodiments, the lifting rod is interference-fitted with the second through hole.

[0013] In some embodiments, the column is a cylinder.

[0014] The target ball measuring fixture provided according to one or more embodiments of this application has an adjustable angle between the lifting rod and the column, and the lifting rod can be operably rotated around the axis of the column, allowing the target ball seat to be set around the column. The target ball seat can be adjusted within a wide range of angles. The adjustment component is slidable on the column, meaning the distance between the adjustment component and the seat is adjustable. The distance between the target ball seat and the adjustment component is also adjustable, meaning the distance between the target ball seat and the seat is also adjustable. The target ball seat can be adjusted within a wide range of distances. The arc surface of the base magnetically adheres to the roller surface, resulting in stronger stability. Even if the target ball seat is far from the roller surface and has an angle with the vertical plane containing the axis of the roller, the seat can still keep the target ball seat stable and prevent it from falling off the roller surface. This allows the target ball seat to be precisely adjusted during the measurement process, reducing measurement errors caused by the target ball seat and improving measurement accuracy.

Detailed Implementation

[0017] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0018] This application is described below with reference to the accompanying drawings and specific embodiments: Please see Figures 1-3 According to a first aspect of this application, a target ball measuring fixture is provided, including a base 100, a column 200, an adjustment assembly 300, a lifting rod 400, and a target ball seat 500.

[0019] The bottom surface of the base 100 has a concave arc surface, and the bottom surface of the base 100 is operablely magnetic. That is, when the base 100 is magnetic, the arc surface of the bottom surface of the base 100 will make at least two contact points between the base 100 and the roller surface to be measured of multiple sizes, thereby improving the stability of the base 100 on the roller surface.

[0020] The column 200 is located at the top of the base 100, and the adjustment component 300 is operably slidable or fixedly located on the column 200; the lifting rod 400 is located on the adjustment component 300, and the angle between the lifting rod 400 and the column 200 is operably adjustable; the lifting rod 400 is operably rotatable around the axis of the column 200; the target ball seat 500 is located at one end of the lifting rod 400, and the distance between the target ball seat 500 and the adjustment component 300 is operably adjustable; so that the target ball seat 500 can approach or move away from the column 200, and so that the target ball seat 500 can rotate around the column 200.

[0021] The adjustable angle between the lifting rod 400 and the column 200, and the operable rotation of the lifting rod 400 around the axis of the column 200, allow the target ball seat 500 to be positioned around the column 200, providing a wide range of adjustable angles. The adjusting component 300 is slidable on the column 200, meaning the distance between the adjusting component 300 and the base 100 is adjustable. The distance between the target ball seat 500 and the adjusting component 300 is also operable, meaning the distance between the target ball seat 500 and the base 100 is also adjustable, providing a wide range of adjustable distances. The curved magnetic attraction of the base to the roller surface enhances stability. Even if the target ball seat 500 is far from the roller surface and forms an angle with the vertical plane containing the roller's axis, the base 100 ensures the target ball seat 500 remains stable and does not fall off the roller surface. This allows for precise position adjustment of the target ball seat 500 during measurement, reducing measurement errors caused by the target ball seat 500 and improving measurement accuracy.

[0022] In some embodiments, an arc-shaped plate 110 is provided at the bottom end of the base 100, and the bottom surface area of ​​the arc-shaped plate 110 is larger than the arc surface area of ​​the bottom surface of the base 100. If the bottom surface of the base 100 is magnetic, the arc-shaped plate 110 is also magnetic. Increasing the contact area between the base 100 and the roller surface further improves the stability of the base 100 on the roller surface.

[0023] In some embodiments, the curved plate 110 has toughness.

[0024] Understandably, when the diameter of the roller surface where the arc surface of the base 100 is located is larger than the diameter of the roller to be measured, the contact point between the bottom surface of the base and the roller surface is on a line, which has a certain degree of instability. The arc plate 110 has toughness, so after the base 100 and the arc plate 110 become magnetic, the magnetic attraction of the roller surface to the arc plate 110 will cause the arc plate 110 to deform, thereby allowing the arc plate 110 to fit against the roller surface, increasing the contact area between the arc plate 110 and the roller surface, thereby increasing the magnetic force and improving the stability of the base 100. This can reduce the situation where the base 100 moves on the roller surface due to the gravity of the target ball seat 500, and improve the measurement accuracy of the target ball measuring fixture in dealing with various measurement conditions.

[0025] In some embodiments, the thickness of the arc-shaped plate 110 gradually decreases from the center to both sides along the arc direction. When the arc-shaped plate 110 is disposed on the roller surface, the axial direction of the roller surface is perpendicular to the arc direction of the arc-shaped plate 110. The fact that the thickness of the arc-shaped plate 110 gradually decreases from the center to both sides along the arc direction means that the greater the range of deformation that the arc-shaped plate 110 can undergo under magnetic force, the easier it is for the arc-shaped plate 110 to conform to the roller surface, the larger the contact area, and the stronger the magnetic force between the arc-shaped plate 110 and the roller surface.

[0026] Considering that there are rollers of various diameters in the factory area, in some embodiments, the arc plate 110 is detachably mounted on the bottom surface of the base 100. This facilitates the replacement of arc plates 110 with different curvatures and sizes, enabling the target ball measuring fixture of this embodiment to be applied to the measurement of various rollers in the factory area, with high adaptability and correspondingly high measurement accuracy for different rollers.

[0027] In some embodiments, the bottom surface of the base 100 is provided with a snap-fit ​​groove, and the arc-shaped plate 110 is provided with snap-fit ​​posts along its length direction, with the snap-fit ​​posts slidably connected to the snap-fit ​​groove. That is, the arc-shaped plate 110 is detachably mounted on the bottom surface of the base 100 by snap-fit. The snap-fit ​​groove can be a T-shaped groove that penetrates the bottom surface of the base 100, and the snap-fit ​​post is a T-shaped post that matches the shape of the T-shaped groove.

[0028] Please see Figure 2 The base 100 is a magnetic base. Operators can easily rotate the handle 120 on the magnetic base to make it magnetic or non-magnetic, simplifying operation. Furthermore, the base 100 requires no wiring, making it easy for operators to carry and use, and highly adaptable. Of course, in some embodiments, the base 100 can also be an electromagnet, where energizing the bottom surface and / or the curved plate 110 makes it magnetic.

[0029] Please see Figures 1-3 In some embodiments, the adjustment assembly 300 includes a first adjustment seat 310, a locking member 330, and a second adjustment seat 320. The first adjustment seat 310 has a hoop 311 and clamping arms 312 disposed on both sides of the hoop 311. Both clamping arms 312 are provided with first through holes. One end of the locking member 330 is provided with a first connecting part 332, and the other end of the locking member 330 is provided with a handle 331. One end of the second adjustment seat 320 is provided with a second through hole 322, which is sleeved on the lifting rod 400. The other end of the second adjustment seat 320 is provided with a second connecting part 321. The first connecting part 332 passes through at least one first through hole and connects with the second connecting part 321 so that the hoop 311 clamps the column 200.

[0030] Understandably, when the hoop 311 is clamping the column 200, the position and height of the adjusting component 300 on the column 200 can be adjusted. After the operator operates the handle 331 and one end of the second adjusting seat 320 to connect the first connecting part 332 and the second connecting part 321, the two clamping arms 312 can come close together to deform the hoop 311 and clamp the column 200, thus fixing the position of the adjusting component 300 on the column 200.

[0031] In some embodiments, the column 200 is cylindrical to facilitate adjustment of the orientation of the target ball base 500 relative to the column 200.

[0032] The first connecting part 332 is a stud, and the second connecting part 321 is a columnar member with an internal thread that matches the thread of the stud. Alternatively, the first connecting part 332 can be a columnar member with an internal thread, and the second connecting part 321 can be a stud with an internal thread that matches the thread. After the first and second connecting parts are connected, the handle 331 and the second adjusting seat 320 can be considered as a whole and can rotate within the first through hole. This allows the contact parts of the first through hole and the second adjusting seat 320 to have an interference fit, enabling the lifting rod 400 to rotate relative to the first adjusting seat 310 under the action of an external force, and to remain relatively stationary with the first adjusting seat 310 after rotation without the action of an external force. Alternatively, a positioning plate with an arc-shaped hole can be provided on the telescopic rod, and a positioning threaded hole can be provided on the first adjusting seat 310. After adjusting the angle between the telescopic rod and the first adjusting seat 310, a screw is used to thread through the arc-shaped hole and connect to the positioning threaded hole. The pressure transmitted to the positioning plate through the nut fixes the angle between the lifting rod 400 and the first adjusting seat 310.

[0033] In some embodiments, the lifting rod 400 is interference-fitted with the second through hole 322. That is, without external force, the second adjusting seat 320 can clamp the lifting rod 400 at the second through hole 322. When an operator applies external force to pull the lifting rod 400, relative sliding can occur between the second adjusting seat 320 and the lifting rod 400, thereby adjusting the distance between the target ball seat 500 and the column 200. In other embodiments, the second adjusting seat 320 and the lifting rod 400 can be fixedly connected by adhesive or bolts. The lifting rod 400 is a telescopic rod with adjustable length; adjusting the length of the telescopic rod also achieves the function of adjusting the distance between the target ball seat 500 and the column 200.
