[0002] Inspection is an essential part of manufacturing and an important component of the six major factors affecting product quality: people, machines, materials, methods, environment, and measurement. Real-time inspection of products can not only detect quality problems in a timely manner, but also improve production consistency based on the inspection data.

[0003] Most existing scanning and inspection methods involve mounting scanning and inspection components on robot articulated arms. These components typically include sensors, and software programs control the movement of the scanning and inspection components and sensors to perform non-contact inspection of the workpiece surface.

[0004] In actual testing, collisions between the scanning part and the workpiece can occur, damaging components such as the scanner's ball cage or the sensor. Sensor installation is complex, difficult to operate, and the sensor's installation angle is hard to adjust, resulting in low testing efficiency.

[0005] Therefore, it is necessary to develop a new scanning and detection device to address the aforementioned defects and drawbacks of current measurement technologies. Summary of the Invention

[0006] The purpose of this utility model is to provide a scanning detection structure and a measuring device for a measuring device. The scanning detection structure is compact and small in size, and the sensor can be installed facing into the ball cage, which can effectively avoid the defect of the sensor being exposed and thus colliding with the workpiece to be measured.

[0007] Therefore, this utility model provides a scanning detection structure for a measuring device, comprising: a sensor; a ball cage frame including multiple connecting rods, the multiple connecting rods surrounding multiple connecting through holes; a mounting assembly disposed within the connecting through holes, comprising: a connecting portion, the connecting portion having a first connecting hole and multiple second connecting holes, the multiple second connecting holes being evenly distributed circumferentially around the center of the first connecting hole; the second connecting holes being used to connect to the sensor, the first connecting holes corresponding to the ultrasonic generator of the sensor; and multiple adapter portions, the multiple adapter portions being equally spaced around the periphery of the connecting portion, the adapter portion having a connecting frame connected to one end away from the connecting portion, the connecting frame being used to connect the mounting assembly to the connecting rods.

[0008] Preferably, the center of the first connecting hole coincides with the center of the connecting portion.

[0009] Preferably, the sensor has at least one threaded connection hole, which corresponds to the second connection hole and is connected by a bolt.

[0010] Preferably, the plurality of the adapter portions are arranged at an angle clockwise or counterclockwise around the periphery of the connecting portion.

[0011] Preferably, the radial angle between the adapter and the connecting part is an acute angle.

[0012] Preferably, the connecting through hole is triangular and is formed by three connecting rods; the number of connecting brackets is three, and the three connecting brackets are respectively connected to the three connecting rods.

[0013] Preferably, the connecting frame is U-shaped, the connecting frame is fastened to the connecting rod, and the open end of the connecting frame abuts against and is connected to the adapter.

[0014] Preferably, the open end of the connecting frame is provided with a threaded groove, and the adapter is provided with a connecting hole corresponding to the threaded groove.

[0015] Preferably, the inner wall of the connecting frame is covered with a cushioning layer.

[0016] This utility model provides a measuring device, including a robot, and also includes the scanning and detection structure for the measuring device; a connecting arm is connected to the ball cage frame, and the connecting arm is connected to the robot.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This utility model provides a scanning detection structure and a measuring device for a measuring device. The scanning detection structure for the measuring device includes: a sensor; a ball cage frame, which includes multiple connecting rods, the multiple connecting rods surrounding multiple connecting through holes; a mounting assembly, which is disposed in the connecting through holes, and includes: a connecting part, the connecting part having a first connecting hole and multiple second connecting holes, the multiple second connecting holes being evenly distributed around the center of the first connecting hole; the second connecting holes are used to connect to the sensor, and the first connecting holes correspond to the ultrasonic generator of the sensor; multiple adapter parts, the multiple adapter parts being equally spaced around the periphery of the connecting part, and a connecting frame being connected to one end of the adapter part away from the connecting part, the connecting frame being used to connect the mounting assembly to the connecting rods.

[0018] (1) This application allows the sensor to be installed on the mounting assembly in a convenient and quick manner, and the installation angle of the sensor on the mounting assembly can be adjusted so that the sensor can perform scanning detection, thereby improving detection efficiency and detection accuracy.

[0019] (2) The present application can conveniently and quickly install the sensor in the connecting through hole of the ball cage frame by means of the installation component. Multiple sensors can be distributed along the spherical surface of the ball cage frame, so that when the scanning detection structure of the present application works at different angles, one or more sensors can perform scanning detection, thereby improving detection efficiency and detection accuracy.

[0020] (3) In this application, the sensor can be oriented towards the inside of the ball cage frame according to actual usage requirements (e.g., Figure 1 , Figure 2 (As shown) Install, or choose to face the sensor outwards from the cage frame (e.g. Figure 3 , Figure 4 The installation is as shown, and no specific restrictions are imposed here; as long as the ultrasonic generator of the sensor can correspond to the first connection hole and the ultrasonic waves emitted by the ultrasonic generator are not blocked, it is acceptable.

[0021] By oriented the entire sensor toward the inside of the cage (e.g.) Figure 1 , Figure 2 As shown, this installation method minimizes the size of the scanning detection structure and reduces the field of view occupied by the sensor within the spherical cage. This results in a compact and small-sized structure, effectively preventing sensor occupancy from obstructing target tracking, thereby improving detection efficiency and quality. Simultaneously, it effectively avoids sensor exposure, preventing sensor damage from collisions.

[0022] Other features and advantages of this utility model will become clearer after reading the detailed embodiments of this utility model in conjunction with the accompanying drawings. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] like Figures 1-8 As shown, the scanning detection structure for measuring devices of this utility model includes: a sensor 10; a ball cage frame 20, which includes multiple connecting rods 21, the multiple connecting rods 21 forming multiple connecting through holes 22; and a mounting assembly 30, which is disposed within the connecting through holes 22, and includes: a connecting part 31, the connecting part 31 having a first connecting hole 311 and multiple second connecting holes 312, the multiple second connecting holes 312 being evenly distributed around the center of the first connecting hole 311; the second connecting holes 312 being used to connect to the sensor 10, and the first connecting holes 311 corresponding to the ultrasonic generator 11 of the sensor 10; and multiple adapter parts 32, the multiple adapter parts 32 being equally spaced around the periphery of the connecting part 31, the end of the adapter part 32 away from the connecting part 31 being connected to a connecting frame 33, the connecting frame 33 being used to connect the mounting assembly 30 to the connecting rods 21.

[0033] Sensor 10 can be an ultrasonic distance sensor commonly used in this technical field, and no specific limitations are made here.

[0034] The connecting part 31 and the multiple adapter parts 32 can be a single piece. The connecting part 31 and the multiple adapter parts 32 can be integrally formed by processing technology, and no specific restrictions are made here.

[0035] The connecting part 31 has a plate-like structure, and the transition part 32 is also a plate-like structure coplanar with the connecting part 31. The connecting part 31 and the multiple transition parts 32 form a symmetrical shape, which can make the overall force of the mounting assembly 30 uniform and facilitate the installation and connection of the mounting assembly 30 in the connecting through hole 22.

[0036] The sensor 10 is provided with at least one threaded connection hole, which corresponds to one of the second connection holes 312 and is connected by bolts, thereby mounting the sensor on the mounting assembly 30.

[0037] The center of the first connecting hole 311 coincides with the center of the connecting part 31, meaning the first connecting hole 311 is located at the center of the mounting assembly 30. The ultrasonic generator 11 of the sensor 10 corresponds to the first connecting hole 311, meaning the ultrasonic generator 11 of the sensor 10 is located at the center of the mounting assembly 30. By setting the first connecting hole 311 to correspond to the ultrasonic generator 11 of the sensor 10, on the one hand, it can limit the installation and connection of the sensor 10, facilitating the installation of the sensor 10 on the mounting assembly 30; on the other hand, it can prevent the ultrasonic waves emitted by the ultrasonic generator 11 from being blocked.

[0038] The first connecting hole 311 can be a circular through hole, and the second connecting hole 312 can be an arc-shaped through hole. The number of second connecting holes 312 can be 2, 3, 4, or more, without any specific limitation. The multiple second connecting holes 312 are evenly distributed around the center of the first connecting hole 311 along the circumference.

[0039] By setting multiple second connection holes 312, the sensor 10 can be installed and connected. Since the second connection hole 312 is an arc-shaped elongated hole, it is easy to adjust the installation position and installation angle of the sensor 10 in the second connection hole 312. On the other hand, it is easy to route the cable connected to the sensor 10, avoiding messy cables and preventing cables from blocking the ultrasonic waves emitted by the ultrasonic generator 11.

[0040] In this embodiment, the connecting through hole 22 is triangular and is formed by three connecting rods 21. There are three corresponding adapter parts 32 and three connecting brackets 33, which are respectively connected to the three connecting rods 21.

[0041] Specifically, the connecting frame 33 is U-shaped and is fastened to the connecting rod 21. The open end of the connecting frame 33 abuts against and connects to the adapter 32.

[0042] The open end of the connecting bracket 33 is provided with a threaded groove, and the adapter 32 is provided with a connecting hole 34 corresponding to the threaded groove. During installation, the connecting bracket 33 is first fastened onto the connecting rod 21, and then the two ends of the opening of the connecting bracket 33 are respectively connected to the adapter 32 with bolts, so that the entire mounting assembly 30 can be installed on the ball cage frame 20. The bolt connection method allows for convenient and quick installation and removal of the mounting assembly 30.

[0043] The inner wall of the connecting frame 33 is covered with a cushioning layer (not shown in the figure). The cushioning layer can be a rubber pad or a foam pad, which can protect the connecting rod 21 and prevent it from being scratched. In addition, it can also strengthen the connection, so that the connecting frame 33 can be firmly and reliably fastened to the connecting rod 21, thereby allowing the mounting assembly 30 to be firmly and reliably installed on the ball cage frame 20.

[0044] Preferably, the adapter 32 and the connecting frame 33 are made of flexible materials, such as polyoxymethylene (POM), which can achieve a flexible connection to the connecting rod 21, protect the connecting rod 21, and prevent the adapter 32 and the connecting frame 33 from causing the connecting rod 21 to bend and deform.

[0045] In this embodiment, the adapter 32 is not distributed radially along the connecting part 31, but rather the multiple adapters 32 are arranged in a clockwise or counterclockwise tilt around the periphery of the connecting part 31.

[0046] In this embodiment, since the ball cage frame 20 is spherical in shape, multiple connecting through holes 21 are distributed along the spherical surface of the ball cage frame 20; multiple adapters 32 are arranged clockwise or counterclockwise around the periphery of the connecting part 31, which facilitates the corresponding cooperation between the adapter 32 and the connecting rod 21, and further facilitates the connection and installation of the mounting component 30 on the connecting rod 21.

[0047] Preferred, such as Figure 6 As shown, the radial angle α between the adapter 32 and the connecting part 31 is an acute angle, which facilitates the corresponding engagement of the adapter 32 and the connecting rod 21, and further facilitates the connection and installation of the mounting assembly 30 on the connecting rod 21.

[0048] Multiple tracking targets 23 are connected to the ball cage frame 20. The tracking targets 23 are multiple target balls arranged on the ball cage frame 20. Specifically, the tracking targets 23 are installed at the end of the connecting rod 21 and located at the corner of the connecting through hole 22. The installation and connection method of the tracking targets 23 can be a common method in this technical field, and no specific limitation is made here.

[0049] This embodiment also provides a measuring device, including a robot (not shown in the figure), and a scanning detection structure for the measuring device in this embodiment; a connecting arm 24 is connected to the ball cage frame 20, and the connecting arm 24 is connected to the robot.

[0050] The robot moves the ball cage frame 20, which in turn moves the sensor 10 and the tracking target 23, so that the sensor 10 and the tracking target 23 can perform non-contact detection on the target detection points on the surface of the component to be tested.

[0051] The advantages and positive effects of this utility model include:

[0052] (1) This application allows the sensor 10 to be conveniently and quickly installed on the mounting assembly 30, and the mounting angle of the sensor 10 on the mounting assembly 30 can be adjusted so that the sensor 10 can perform scanning detection.

[0053] (2) The sensor 10 can be installed in the connection through hole 22 of the ball cage frame 20 by the mounting component 30. Multiple sensors 10 can be distributed along the spherical surface of the ball cage frame 20, so that when the scanning detection structure of the present application works at different angles, one or more sensors 10 can perform scanning detection.

[0054] In this application, there is no specific limit to the number of sensors 10 installed on the ball cage frame 20. The number of sensors 10 installed can be selected according to actual usage requirements.

[0055] (3) In this application, the sensor 10 can be positioned facing inwards towards the ball cage frame 20, depending on actual usage requirements (e.g., Figure 1 , Figure 2 (As shown) Install, or choose to face the sensor 10 outwards towards the cage frame 20 (e.g. Figure 3 , Figure 4 The installation is as shown, and no specific restrictions are made here; as long as the ultrasonic generator 11 of the sensor 10 can correspond to the first connection hole 311, the ultrasonic waves emitted by the ultrasonic generator 11 are not blocked.

[0056] By aligning the sensor 10 entirely within the cage frame 20 (e.g.) Figure 1 , Figure 2 The installation method shown can minimize the volume of the scanning detection structure and the field of view occupied by the sensor 10 in the ball cage, effectively preventing the sensor 10 from obstructing the tracking target 23, thereby improving the detection efficiency and quality of the scanning detection structure. At the same time, it can effectively prevent the sensor 10 from being exposed and prevent the sensor 10 from being collided with.

[0057] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by this utility model.
