Description

Technical Field

[0001] This utility model relates to the field of intelligent manufacturing technology, and in particular to a sampling device for an intelligent bevel gear production system. Background Technology

[0002] In some intelligent bevel gear production systems, the equipment in the workshop is often arranged in a U-shape according to the process flow, and the operators carry out relevant operations in the workshop through the gaps in this U-shape.

[0003] To ensure that the machining accuracy of the bevel gears meets the technical requirements, it is necessary to conduct random quality checks on the finished bevel gears frequently.

[0004] Randomly selected bevel gear samples are picked up by the gripper on the robot's end effector and transferred to the sampling device. When the sampling device enters the workshop along the U-shaped notch, it is necessary to determine whether the sampling device for placing bevel gears is stopped in the designated position before the gripper starts moving, so that the gripper can accurately place the bevel gear samples on the sampling table. It is also necessary to prevent operators from being in the area where the U-shaped notch is located to ensure the safety of the sampling operation. Summary of the Invention

A mirror reflection sensor is installed at the end of one triangular bracket, and a reflector plate is provided at the end of the other triangular bracket to receive and reflect the signal sent by the mirror reflection sensor through the radial hole.

[0010] The guide frame has concave ball bearings with openings facing the trolley bracket installed on both sides of its front end, and convex ball bearings that can engage with the concave ball bearings are installed on both sides of the lower end face of the front end of the trolley bracket.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] like Figures 1-2 As shown, an intelligent bevel gear production system sampling device enters the sampling area along the U-shaped notch formed by the arrangement of equipment in the production system. The bevel gear samples taken include a disc bevel gear 23 with a larger gear diameter and a bevel shank bevel gear 24 with a smaller gear diameter.

[0025] A protective door frame 1 is fixed to the ground at the U-shaped notch. The protective door frame 1 has two columns set apart from each other, and a crossbeam is fixed between the upper ends of the columns. A guide frame 2 is set below the protective door frame 1. The guide frame 2 is fixed to the ground by adjustable supports at its four corners. The rear end of the guide frame 2 is located between the two columns of the protective door frame 1, and a rectangular column is horizontally fixed on the front end of the guide frame 2.

[0026] The sampling device includes a trolley support 3, with directional casters installed at the four corners of the bottom of the trolley support 3. A trolley handle 22 is installed on the rear side of the trolley support 3. The trolley support 3 is pushed by the trolley handle 22 to roll into the sampling area along the gap between the two sides of the guide frame 2 and the column of the protective door frame 1 until the front face of the trolley support 3 approaches the rectangular column of the front face of the guide frame 2.

[0027] The upper surface of the trolley bracket 3 is fixed with a platform 8, and a tooling plate 4 for placing the disc bevel gear 23 is fixed on the platform 8. The tooling plate 4 is provided with four layers of arc plates 10 whose diameter gradually decreases from top to bottom. The outer circumference of each layer of arc plates 10 matches the inner hole of the disc bevel gear 23. A positioning sleeve 5 for placing the bevel shank bevel gear 24 is provided at the center of the tooling plate 4. The positioning sleeve 5 has a radial hole 5-1 with an axis parallel to the protective door frame 1.

[0028] Triangular brackets 11 are fixed on the inner sides of the columns on both sides of the protective door frame 1. One of the triangular brackets 11 is equipped with a mirror reflection sensor 12 at one end, and the other triangular bracket 11 is provided with a reflector plate 13 that receives and reflects the signal sent by the mirror reflection sensor 12 through the radial hole 5-1.

[0029] A sensor base 16 is fixed on the inner side of the same column as the triangular bracket 11 on which the mirror reflection sensor 12 is installed. An upper proximity switch 6 is installed on the sensor base 16 to detect the upper position of the trolley bracket 3. A sensor bracket 17 is fixed on the rectangular column at the front end of the guide frame 2. A lower proximity switch 7 is installed on the sensor bracket 17 to detect the lower position of the front end of the trolley bracket 3. Correspondingly, a detection plate 18 corresponding to the detection end of the lower proximity switch 7 is installed below the front end of the trolley bracket 3.

[0030] When the trolley support 3 enters the sampling area along the gap between the two sides of the guide frame 2 and the upright of the protective door frame 1, the upper proximity switch 6 first detects the upper position of the trolley support 3, indicating that an object or person has entered the sampling area. As the trolley support 3 gradually enters, the lower proximity switch 7 detects the detection plate 18 below the front end of the trolley support 3, and the trolley support 3 stops. This confirms that the trolley support 3 has moved into place, ensuring the accuracy of the sampling position, and also confirms that an object has entered the sampling area, thus effectively preventing safety hazards caused by operators entering the sampling area.

[0031] See Figure 3 The guide frame 2 has concave ball bearings 14 with openings facing the trolley bracket 3 installed on both sides of the rectangular column at its front end. The trolley bracket 3 has convex ball bearings 15 installed on both sides of its lower front end face. The trolley bracket 3 is locked in place by the snap-fit ​​engagement between the convex ball bearings 15 and the concave ball bearings 14, thereby improving the accuracy of the trolley bracket 3's stopping position and ensuring that the robot gripper can accurately place the bevel gear sample onto the tooling plate 4 or the positioning sleeve 5. See also... Figure 5 , Figure 6 During sampling, the robot gripper picks up the bevel gear sample from the inspection, and the shaft end of the bevel shank bevel gear 24 is placed in the inner hole of the positioning sleeve 5, with the gear part placed on the upper end face of the positioning sleeve 5; or the disc bevel gear 23 is placed on the tooling plate 4, with its inner hole matching the arc plate 10 of the corresponding diameter. After sampling is completed, the trolley bracket 3 exits the sampling area.

[0032] Since there is oil on the bevel gear sample, a water collection tank 9 for collecting oil and water is fixed on the bottom surface of the platform 8. A water collection hole communicating with the top of the water collection tank 9 is opened in the center of the tooling plate 4. A control ball valve for discharging oil and water from the bottom of the water collection tank 9 is installed.

[0033] See Figure 4 The guide frame 2 is equipped with flow rails 19 on both sides. The flow rails 19 are fitted with the two sides of the trolley support 3 with a clearance. Under the guidance of the flow rails 19, the trolley support 3 can enter the sampling area more smoothly.

[0034] To improve the safety of sampling operations, a protective net 20 is installed on the upper end of the protective door frame 1, and a protective plate 21 is fixed on the platform 8 at the rear end of the trolley bracket 3. The height of the protective plate 21 is lower than the bottom of the protective net 20.

[0035] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
