Description

Technical Field

[0001] This utility model relates to the technical field of control valve testing equipment, and in particular to a control valve rotation testing device. Background Technology

[0002] Control valves are used to regulate fluid flow to control process parameters such as pressure, temperature, level, and flow rate. They achieve precise control of fluid flow by changing the size of the fluid passage. For example, an engine fuel injection control valve controls engine fuel injection. After processing, its appearance needs to be inspected, typically by photographing the surface to be inspected using a vision inspection system. When inspecting the side of the control valve, because it is a circumferential surface, a rotating mechanism is needed to rotate the product, and a separate positioning mechanism is required to position the product during rotation. Current solutions typically involve clamping the product's side and then rotating it for photographing. However, the grippers can obstruct the product's side and easily damage it. Utility Model Content

[0003] The purpose of this invention is to solve the technical problem that existing testing devices are difficult to locate when performing peripheral appearance inspection.

[0004] To achieve the objectives of this utility model, the following technical solution is adopted: A control valve rotation detection device includes a support base and a rotation mechanism disposed below the support base. The rotation mechanism includes a positioning component, a drive component, and a rotation component. The positioning component is disposed in the support base. The drive component includes a shaft, a first drive member, and a mounting base connected to the shaft. The shaft is inserted into the mounting base and is movably connected to the mounting base along the axial direction. When the shaft extends, the positioning component inserts into a hole at the end of the product to fix the product. When the shaft retracts, the positioning component releases the product. The first drive member is connected to the shaft through a floating component and drives the shaft to extend and retract axially. The rotation component is connected to the mounting base and drives the mounting base and the shaft to rotate around the axial direction.

[0005] In some embodiments, the positioning component includes a plurality of grippers arranged around the axial direction, the grippers being movably disposed in and extending out of the support, and the inner wall of the grippers contacting the inner support block at the end of the shaft via an inclined conical surface.

Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0025] <Example 1> like Figure 1 , Figure 2 and Figure 5 As shown, this embodiment provides a control valve rotation detection device for detecting a control valve 10. The product 10 is generally cylindrical, having an upper plane 101, a lower plane 102, and a circumferential surface 103 disposed between the upper and lower planes. The upper plane 101 has an upper hole 104, and the circumferential surface 103 has three side holes 105. The control valve rotation detection device of this embodiment is used to detect the appearance of the circumferential surface 103. The control valve rotation detection device includes a positioning component 2, a driving component 3, and a rotation component 4. The positioning component 2 is disposed in a support base 231. The driving component 3 includes a shaft 32, a first driving member 31, and a mounting base 33 connected to the shaft 32. The shaft 32 is inserted into the mounting base 33, and the shaft 32 and the mounting base 33 are movably connected along the Y-axis. When the shaft 32 extends, the positioning component 2 inserts into the product end face hole 104 to fix the product. When the shaft 32 retracts, the positioning component 2 releases the product. That is, when the shaft 32 rises, it can drive the positioning component 2 to fix the product 10, thus maintaining stability during rotation. When the shaft 32 descends, the positioning component 2 releases the product 10, allowing it to be removed. The first driving member 31 is connected to the shaft 32 via the floating component 5. The first driving member 31 drives the shaft 32 to extend and retract axially. The first driving member 31 is a cylinder, and the cylinder's extension rod is coaxially arranged with the shaft 32 and connected via the floating component 5. In the Y-axis direction, the extension and retraction of the cylinder's extension rod 311 can drive the shaft 32 to move synchronously via the floating component 5. When the rotating component 4 drives the shaft 32 to rotate, the floating component 5 prevents the cylinder's extension rod and the shaft 32 from rotating synchronously. The floating component 5 enables the shaft 32 and the extension rod to move synchronously axially but asynchronously in the rotation direction. The rotating component 4 is connected to the mounting base 33, driving the mounting base 33 and the shaft 32 to rotate around the axis. In this embodiment, the rotation direction is around the axis Y, enabling the product 10 to rotate around the axis Y, facilitating detection by the horizontally oriented third vision inspection component 233. In this embodiment, the shaft 32 and the mounting base 33 move synchronously in the rotation direction and relatively in the axis Y direction, thereby enabling the shaft to rotate and move axially. The shaft 32 can be a splined shaft, and the shaft 32 and the mounting base 33 are fitted with a keyway.

[0026] Specifically, the positioning component 2 includes several grippers 21 arranged axially. The grippers 21 are movably disposed within and protrude from the support base 231, meaning the holes on the upper surface of the product 10 fit over the grippers 21, supporting the product 10. The inner wall of the grippers 21 contacts the inner support block 321 at the end of the shaft 32 via an inclined conical surface 22. Thus, when the shaft 32 extends upward, it pushes the grippers 21 outward to expand, thereby pressing the product 10; when the shaft 32 moves downward, the grippers 21 are pulled inward by the gravity of the product 10, releasing the product 10. Through this technical solution, the axial movement of the shaft can control the product's positioning, saving lateral space and facilitating control.

[0027] Furthermore, the positioning component 2 includes a ball-head plunger 23, which is disposed on the support seat 231 and abuts against the gripper 21. The number of ball-head plungers 23 is the same as the number of grippers 21, with each ball-head plunger 23 abutting against one gripper 21. When the gripper 21 expands outward, the ball-head plunger 23 is compressed. When the gripper 21 loses the pressure provided by the shaft, the ball-head plunger 23 provides a restoring force, causing the gripper 21 to retract, which can further increase the retraction speed of the gripper 21 and prevent the product 10 from getting stuck on the gripper 21. The mounting seat 33 is disposed in the bearing seat 34, and a first bearing 35 is provided between the mounting seat 33 and the bearing seat 34, allowing the mounting seat 33 to rotate smoothly.

[0028] Furthermore, the floating assembly 5 includes a floating joint 51 and a connecting seat 52. One end of the floating joint 51 is fixedly connected to the first driving member 31, and the other end abuts against the shaft 32. The floating joint 51 is movably connected to the connecting seat 52, and a second bearing 36 is provided in the connecting seat 52. The shaft 32 is connected to the second bearing 36. When the telescopic rod 311 of the first driving member 31 extends, it drives the floating joint 51 to move upward in the connecting seat 52, thereby pushing the shaft 32 upward. When the telescopic rod 311 retracts, the shaft 32 moves downward. The rotating assembly 4 includes a second driving member 41, which is connected to the mounting seat 33 through a transmission assembly. The second driving member 41 uses a servo motor to provide rotational power to the mounting seat 33. Specifically, the transmission assembly includes a synchronous belt 42, a first pulley 43, and a second pulley 44. The first and second pulleys are respectively sleeved on the rotating shaft of the second driving member 41 and the mounting seat 33, so that the power of the second driving member 41 can be transmitted to the mounting seat 33.

[0029] <Example 2> In this embodiment, the parts that are the same as in Embodiment 1 are given the same reference numerals, and the same text descriptions are omitted.

[0030] like Figure 3 and Figure 4As shown, compared to Embodiment 1, the control valve rotation detection device provided in this embodiment has the following structural design differences: The control valve rotation detection device includes a flipping assembly 232 and a vision detection assembly 233. The flipping assembly 232 is used to rotate the product 180° so that the upper surface faces down and the lower surface faces up. The flipping assembly 232 includes a rotating mechanism 2321 and a drive mechanism 2322 connected to the rotating mechanism 2321. The drive mechanism 2322 drives the rotating mechanism 2321 to reciprocate between the detection position 255 and the support base 231. The detection position 255 is located on a rotating indexing plate and is used to transport the product 10.

[0031] Furthermore, the rotating mechanism 2321 is connected to the height adjustment mechanism 2323, which in turn is connected to the drive mechanism 2322. The drive mechanism 2322 moves the height adjustment mechanism 2323 horizontally, and the height adjustment mechanism 2323 drives the rotating mechanism 2321 vertically, thereby adjusting the position of the rotating mechanism 2321. In this embodiment, the rotating mechanism 2321 uses a rotary cylinder, which works with grippers to pick up or release the product. The height adjustment mechanism 2323 and the drive mechanism 2322 use linear motion devices such as sliding cylinders. After acquiring the product, the rotating mechanism 2321 rotates, placing the upper surface 101 of the product on the support base 231. The visual inspection component 233 is located on the side of the third support base 231. Through the above technical solution, the product can be flipped when transferred to the support base 231, thereby adjusting the product orientation. A rotating mechanism 2321 is provided below the support base 231. The rotating mechanism 2321 drives the product to rotate, enabling the product to rotate around a vertical axis, thereby allowing the visual inspection component 233 to photograph the circumferential surface 103 of the product from the side. After the inspection is completed, the product is placed back on the base of the inspection position by the flipping component 232, without flipping it back. The visual inspection component 233 adopts existing technology and will not be described in detail.

[0032] This utility model uses a positioning component set in the support base, which can be inserted into the product end hole to position the product, avoiding obstruction of the product side and not affecting appearance inspection; in addition, it can move and rotate axially through the shaft, controlling product positioning by moving the shaft axially and driving the product to rotate axially, resulting in higher structural integration and smaller space occupation.

[0033] In the above embodiments one and two, during the working process, depending on the different working environments, some of the technical implementation methods of embodiments one and two can be combined or replaced.

[0034] The technical principles of this utility model have been described above in conjunction with specific embodiments. However, it should be noted that these descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, other specific embodiments or equivalent substitutions of this utility model that can be conceived by those skilled in the art without creative effort will all fall within the scope of protection of this utility model.
