[0031] This part will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The function of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be construed as a limitation on the protection scope of the present invention.

[0032] Refer to Figures 1-5 , an automatic piston outer diameter detection device according to an embodiment of the present invention includes: a base 1. An inclined material rack 2 is arranged on the upper surface of the base 1 to let the material fall. The inclined material rack 2 includes a support frame 21 for holding the raw material. The upper surface of the support frame 21 is inclined to facilitate the inclined sliding. A gentle section 22 is arranged at the right end of the support frame 21 for placing the material to facilitate subsequent connection. A bracket 23 is rotatably connected to the surface of the gentle section 22 to block the sliding parts. One end of the bracket 23 is movably connected to a baffle 24 to block the remaining parts. The baffle 24 is rotatably connected to the support frame 21 to realize the transfer of movement. A blocking plate 25 is fixedly connected to the upper surface of the gentle section 22 to press the connecting plate.

[0033] During the movement, place the parts on the support frame 21, and then let the raw material fall by tilting. The lowermost raw material reaches the gentle section 22 and presses down on the bracket 23, so that the baffle 24 tilts up to block the remaining parts.

[0034] A rotating bracket 3 is arranged on the upper surface of the base 1 and on the right side of the inclined material rack 2 to rotate the workstations. The rotating bracket 3 includes a vertical plate 31. A power motor 32 is fixedly connected to the side surface of the vertical plate 31 to rotate the chuck 36. The output end of the power motor 32 is fixedly connected to a transmission shaft 33. A turntable 34 is fixedly connected to the side surface of the transmission shaft 33. A support rod 35 is fixedly connected to the edge of the turntable 34. There are multiple (shown as four in the figure) support rods 35. A chuck 36 for clamping the detection component 6 is arranged at the end of the support rod 35 to grab the detection component. The chuck 36 is in a clamp shape, and one of the clamp bodies is a movable structure, and the spring provides the supporting force to clamp the detection component 6.

[0035] When in use, the support rod 35 is rotated by the power motor 32. When it rotates to the position of the inclined material rack 2, the detection component 6 is clamped by the chuck 36 to complete the connection. Then, by the rotational force of the power motor 32, the detection component 6 reaches directly below the detection device 4.

[0036] The upper surface of the rotating bracket 3 is provided with a detection device 4. The detection device 4 includes a mounting plate 41, a compaction plate 42, a detection head 43, a return spring 44, a detection piece 45, and a detection plate 46. The length of the detection head 43 is equal to the distance between the mounting plate 41 and the detection plate 46. The detection head 43 contacts the surface of the piston 62 to make surface contact. The mounting plate 41 is fixedly connected to the top end of the vertical plate 31. The return spring 44 is located on the side surface of the detection head 43, and the return spring 44 positions the detection head 43 on the surface of the piston 62. The end of the detection head 43 is provided with a rotating ball to prevent damage to the surface of the piston 6. The detection piece 45 is located at the top of the detection head 43. The detection plate 46 is located above the mounting plate 41 and is fixedly connected to the mounting plate 41. The compaction plate 42 is fixedly connected to the lower surface of the mounting plate 41. A distance sensor is provided on the lower surface of the detection plate 46. During detection, the entire detection device 4 can be replaced with a pneumatic measuring instrument and selected according to different detection accuracies.

[0037] During use, the detection head 43 fits the surface of the piston 6. By rotating the piston 62, the outer diameter of the piston 62 is measured. Since the length of the detection head 43 is equal to the distance between the mounting plate 41 and the detection plate 46, the data detected by the distance sensor is the distance from the monitoring point to the rotation center (i.e., the radius). By calculating through the internal processor, the radius can be obtained, and at the same time, the defects on the piston surface can be known, providing a basis for the errors of the previous production device and making timely corrections to improve the production qualification rate.

[0038] The side surface of the rotating bracket 3 is provided with a rotating part 7 for rotating the piston. The rotating part 7 includes a driving part 71 and a driven part 72. The driving part 71 and the driven part 72 are respectively connected to the two side vertical plates 31 for convenient rotation. The driving part 71 includes a rotating motor 711 to provide the power for rotation. The output end of the rotating motor 711 is fixedly connected with a first electromagnet 712 to provide the power for magnetic attraction, thereby connecting to the corresponding detection component 6. The driven part 72 includes a rotating column 721, and the end of the rotating column 721 is fixedly connected with a second electromagnet 722 to connect to the other end of the detection component.

[0039] During the rotation of the rotating bracket 3, the detection component 6 is adsorbed to the first electromagnet 712 and the second electromagnet 722, thereby completing the rotation action and performing a one-week detection on the surface of the piston 62. Moreover, the first part rotates forward and the second part rotates in reverse, repeating in this way to prevent the entanglement of the wires.

[0040] On the upper surface of the base 1 and on the right side of the rotating bracket 3, there is a blanking rack 5 for removing the pistons after inspection. The blanking rack 5 includes a support plate 51. A sloping plate 52 is fixedly connected to the side surface of the support plate 51 to facilitate the detection component 6 to slide down. An electric push rod 53 is arranged inside the sloping plate 52 to provide the power for extension. The output end of the electric push rod 53 is fixedly connected to an extension rod 54. A hook 55 is arranged on the surface of the extension rod 54 to block the detection component 6. There are two sloping plates 52, arranged vertically and having the same internal structure.

[0041] Based on the result of the inspection, the inspected piston 62 slides down through the blanking rack 5 and then slides into the corresponding area to complete the classification of qualified and unqualified pistons.

[0042] A detection component 6 is arranged on the surface of the inclined rack 2. The detection component 6 includes a connecting shaft 61. A piston 62 is arranged on the outer surface of the connecting shaft 61, which is the main body of the detection. Both ends of the connecting shaft 61 are fixedly connected with connectors 63. The connecting shaft 61 has two sections. One section is inserted into the interior of the piston, and the other section is connected to one end of the piston through a ferrule. The connector 63 is connected to the first electromagnet 712. By engaging them, the corresponding work is completed.

[0043] The device further includes a display screen 8, and a controller is arranged inside the display screen 8.

[0044] Working principle: When in use, the piston is fixed on the connecting shaft 61 and placed on the inclined rack 2. Through the rotation of the rotating rack 3, the detection component 6 on the inclined rack 2 is lifted, so that the detection component 6 is located below the detection device 4. The detection component 6 is fixed by the magnetic attraction of the first electromagnet 712 and the second magnet 713. The detection component 6 is driven to rotate by the rotating motor 711. Then, the outer diameter of the piston 62 is measured by the detection device 4, and the external gap is measured at the same time. According to the detection result, it is displayed on the display screen 8 through the processor. The extension rod 54 inside the blanking rack 5 is extended through the internal controller to remove the corresponding piston 62, and then it enters a cycle to complete the work.

[0045] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the purpose of the present invention.
