[0002] As one of the most commonly used structures in mechanical connections, the machining accuracy of threads directly affects the assembly quality and performance of products. Therefore, thread inspection is a key step in the mechanical manufacturing process.

[0003] Most existing thread inspection equipment adopts a single-station design, meaning that only one workpiece can be inspected at a time. For mass-produced threaded workpieces, frequent loading and unloading of workpieces is required, resulting in a cumbersome inspection process and low overall efficiency. To solve the above problems, this application proposes a two-coordinate thread inspection machine. Utility Model Content

With the synergistic effect of the first and second moving mechanisms, the inspection component can move flexibly in the X and Y axes, quickly adapting to the inspection needs of parts to be inspected in different positions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A two-coordinate thread inspection machine includes a base, a first vertical plate and a second vertical plate fixedly connected to the top of the base, a plurality of clamping plates provided between the first vertical plate and the second vertical plate, two guide rods fixedly connected to the first vertical plate and the second vertical plate, the two guide rods passing through each clamping plate and slidably connected thereto, a crossbeam provided above the base, a first moving mechanism provided between the base and the crossbeam, a slider slidably connected to the crossbeam, a second moving mechanism provided on the crossbeam, a second hydraulic rod fixedly connected to the bottom of the slider, a rectangular frame fixedly connected to the bottom of the second hydraulic rod, a servo motor fixedly connected to the inner bottom of the rectangular frame, a telescopic component fixedly connected to the output end of the servo motor, and a detection component fixedly connected to the bottom of the telescopic component.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3A two-coordinate thread inspection machine includes a base 1, which provides stable support for the entire equipment. All components are directly or indirectly mounted on it. A first vertical plate 2 and a second vertical plate 3 are fixedly connected to the top of the base 1. The first vertical plate 2 and the second vertical plate 3 serve as the support structures on both sides and together form the mounting base for the clamping components. Multiple clamping plates 5 are provided between the first vertical plate 2 and the second vertical plate 3. The first vertical plate 2 and the second vertical plate 3 are jointly and fixedly connected to two guide rods 4. The guide rods 4 provide sliding tracks for the clamping plates 5, ensuring that the clamping plates 5 can only move in a straight line. Both guide rods 4 pass through each clamping plate 5 and are slidably connected to it. Limiting grooves 8 are provided on the side wall of the first vertical plate 2 near the clamping plate 5, the left end of the rightmost clamping plate 5, and the side wall of each of the remaining clamping plates 5. The limiting grooves 8 are used to limit the position of the workpiece 7 to be inspected and prevent it from shifting during the inspection process. Two adjacent limiting grooves 8 together clamp the workpiece 7 to be inspected.

[0020] A crossbeam 13 is provided above the base 1. The crossbeam 13 provides a mounting carrier for the detection mechanism and can be adjusted in position by a first moving mechanism. A first moving mechanism is provided between the base 1 and the crossbeam 13. The first moving mechanism includes two grooves opened on the top of the base 1. A sliding rod 11 is fixedly connected to the inner wall of the left groove. The sliding rod 11 guides the movement of the crossbeam 13 to ensure its stable movement. A first threaded rod 10 is rotatably connected to the inner wall of the right groove. The first threaded rod 10 drives the crossbeam 13 to move linearly through rotation. A first motor 9 is fixedly connected to the front end of the base 1. The first motor 9 provides power for the rotation of the first threaded rod 10. The output shaft of the first motor 9 passes through the base 1 and is rotatably connected to it. The output shaft of the first motor 9 is coaxially fixedly connected to the first threaded rod 10. Two columns 12 are fixedly connected to the bottom of the crossbeam 13. The sliding rod 11 passes through the left column 12 and is slidably connected to it. The first threaded rod 10 passes through the right column 12 and is threadedly connected to it.

[0021] A slider 16 is slidably connected to the crossbeam 13. The slider 16 can slide along the crossbeam 13, driving the detection component below to adjust its lateral position. A second moving mechanism is provided on the crossbeam 13. The second moving mechanism includes a sliding port arranged through the crossbeam 13. The sliding port provides moving space for the slider 16 and restricts its moving direction. The slider 16 passes through the sliding port and is slidably connected to it. A second motor 14 is fixedly connected to the side wall of the crossbeam 13. The second motor 14 provides power for the rotation of the second threaded rod 15. The output shaft of the second motor 14 passes through the crossbeam 13 and is rotatably connected to it. The output shaft of the second motor 14 is coaxially fixedly connected to the second threaded rod 15. The second threaded rod 15 drives the slider 16 to achieve linear movement through rotational movement. The second threaded rod 15 passes through the slider 16 and is threadedly connected to it.

[0022] A second hydraulic rod 17 is fixedly connected to the bottom of the slider 16. The second hydraulic rod 17 can telescopically move, driving the detection component below to adjust its height. A rectangular frame is fixedly connected to the bottom of the second hydraulic rod 17, providing a mounting structure for the servo motor 18. The servo motor 18 is fixedly connected to the inner bottom of the rectangular frame, providing power for the rotation of the detection component 20. A telescopic component 19 is fixedly connected to the output end of the servo motor 18. The telescopic component 19 includes a hollow column 19-1, a block 19-2, a spring 19-3, and a sliding column 19-4. The telescopic component 19 can elastically extend and retract during the detection process to adapt to positional changes during threaded engagement. The hollow column 19-1 passes through the rectangular frame and is rotatably connected to it. The block 19-2 is located in the hollow column 19-1 and is slidably connected to it. The block 19-2 can be located inside the hollow column 19-1. The telescopic assembly 19 slides to achieve the telescopic function. Spring 19-3 is located in the hollow column 19-1 and its two ends are fixedly connected to the inner wall of the hollow column 19-1 and the block 19-2 respectively. Spring 19-3 provides elastic force so that the telescopic assembly 19 returns to its initial state when no force is applied. The side wall of the block 19-2 is fixedly connected to the sliding column 19-4. The sliding column 19-4 passes through the hollow column 19-1 and slides with it. The sliding column 19-4 moves synchronously with the block 19-2, transmitting the telescopic motion to the detection component 20. The detection component 20 is fixedly connected to the bottom of the telescopic assembly 19. The detection component 20 realizes the thread detection function by engaging with the threaded part 7 under test. The center of the part under test 7 has an opening. The detection component 20 includes a fixed cover and a threaded column. The fixed cover and the threaded column are coaxially fixedly connected. The inner wall of the opening has an internal thread that engages with the outer wall of the threaded column.

[0023] In this invention, when multiple test pieces 7 need to be threaded, the operator activates the first hydraulic rod 6 to move the rightmost clamping plate 5 to the right. At this time, the distance between the first vertical plate 2 and the clamping plate 5 is adjusted to its maximum. The operator places the test piece 7 between the first vertical plate 2 and the clamping plate 5, with both ends of the test piece 7 inserted into the corresponding limiting grooves 8. The operator then places the test piece 7 between two clamping plates 5, with both ends of the test piece 7 inserted into the corresponding limiting grooves 8. After arranging multiple test pieces 7, the operator activates the first hydraulic rod 6 to move the rightmost clamping plate 5 to the left. Through the cooperation of the first vertical plate 2 and multiple clamping plates 5, the test piece 7 is clamped and limited (and the X-axis and Y-axis distances between multiple test pieces 7 are fixed). When thread testing of the workpiece 7 is required, the first motor 9 is started to drive the first thread rod 10 to rotate. In conjunction with the sliding rod 11, the two columns 12, the crossbeam 13, the slider 16, the second hydraulic rod 17, the servo motor 18, the telescopic component 19, and the detection component 20 can move in the Y-axis direction. The second motor 14 is started to drive the second thread rod 15 to rotate, causing the slider 16, the second hydraulic rod 17, the servo motor 18, the telescopic component 19, and the detection component 20 to move in the X-axis direction. This allows the workpiece 7 to be tested at different positions to achieve thread testing. When the detection component 20 moves directly above the workpiece 7 to be inspected, the servo motor 18 is activated to drive the telescopic component 19 and the detection component 20 to rotate. The second hydraulic rod 17 is activated to move the rectangular frame, servo motor 18, telescopic component 19, and detection component 20 downwards until the detection component 20 contacts the opening of the workpiece 7. At this point, the second hydraulic rod 17 stops. The detection component 20 rotates, and the threaded engagement between the outer wall of the detection component 20 and the inner wall of the opening causes the detection component 20 to rotate and move downwards into the opening. During this process, the block 19-2 and the sliding column 19-4 slide correspondingly within the hollow column 19-1. The servo motor 18 is then activated. The servo motor 18 rotates its output end in reverse, causing the detection component 20 to rotate and move upward inside the port until the detection component 20 separates from the port. Finally, the second hydraulic rod 17 is activated to drive the servo motor 18, the telescopic component 19, and the detection component 20 to move upward, completing the thread detection of one workpiece 7. This method is repeated to detect the threads of multiple workpieces 7. The thread detection result can be known by visually observing the downward movement distance of the detection component 20. The thread quality can be judged by observing the downward movement distance of the detection component 20 (when the detection component 20 moves to the bottom, it means that the thread detection is normal; otherwise, it means that there is a quality problem).
