Technical Field

[0001] The utility model belongs to the technical field of tools and fixtures, and particularly relates to a detection and support device for thin-walled cylindrical parts. Background Art

[0002] Thin-walled cylindrical parts require post-processing inspection for dimensions such as wall thickness, roundness, and straightness. While random inspection can be performed on the equipment after machining, it is not possible to perform measurements after the parts are removed from the machine. If random inspections are still performed on the equipment after mass production, production cycles cannot be met and the next process may be delayed. To address this issue, there is an urgent need for an inspection support device to improve part inspection efficiency and accuracy. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] Figure 1 As shown, the utility model provides a detection support device, including: a positioning block 1, a base plate 2, a tapered pin 3, a screw 4, a bearing 5, a pin shaft 6, a nut 7, a washer 8, a support body 9, and a lifting ring 10.

[0022] The positioning block 1 is a small rectangular parallelepiped, plate-like in shape. The narrow end face of the rectangular parallelepiped is designed with two threaded holes, which are mounted on the end face of the support 9 by screws 4 to limit the axial movement of the measured part and play a positioning role.

[0023] The base plate 2 is a rectangular, plate-like structure with eight threaded holes, four dowel pin holes, and two waist-shaped holes designed on its end. The base plate 2 serves as the foundation of the entire device, and two supports 9 are mounted on it. The four dowel pin holes determine the position of the supports 9, ensuring consistent dimensions between the front and rear supports 9 of the test device. The two waist-shaped holes are designed for mounting lifting rings 10.

[0024] The cone pin 3 is cylindrical in shape, and the cylinder is a tapered cylinder with a large size at one end and a small size at the other end. The cone pin 3 is used to connect the support body 9 and the base plate 2, and plays a positioning role to prevent the support body 9 from moving on the upper end surface of the base plate 2 after the screws are loosened during long-term use.

[0025] The screw 4 is a hexagon socket screw, used to connect and fasten the support body 9 to the base plate 2 .

[0026] The bearing 5 is a standard bearing part. The four bearings 5 are connected by a pin 6, which is installed in the notch of the support body 9 and fixed in the notch of the support body 9 by a nut 7. The measured part can roll on the bearing 5.

[0027] The pin 6 is cylindrical, with an external hexagonal shape on one end and an external thread on the other. The outer diameter of the pin 6 forms an interference fit with the inner diameter of the bearing 5. This ensures that the inner diameter of the bearing 5 is fixed to the outer diameter of the pin 6 after the pin 6 is installed, and the part being tested can rotate on the outer diameter of the bearing 5.

[0028] The nut 7 has an external hexagonal internal thread structure. The internal thread of the nut 7 cooperates with the external thread at one end of the pin 6. The nut 7 is screwed into the external thread at one end of the pin 6 to fix the pin 6 and the bearing 5 to the middle rectangular through groove of the support body 9.

[0029] The washer 8 is an annular structure. The inner diameter of the washer 8 matches the outer diameter of the pin 6. The washer 8 is installed on the pin 6 to increase friction and is locked with a nut 7.

[0030] The cross section of the support body 9 is T-shaped, and a rectangular through slot is designed in the middle of the vertical part of the T-shape for mounting the bearing 5, the pin 6, the nut 7 and the washer 8 on it. The side of the support body 9 is a circular arc depression in the middle (such as Figure 3 ), to avoid measuring parts.

[0031] The lifting ring 10 is made of cylindrical steel bars into a circular ring, and the lower end of the ring is provided with a threaded connecting rod. The two lifting rings 10 are installed on the two threaded holes on the bottom plate 2 for installing hooks when lifting the detection device.

[0032] Connection relationship: The positioning block 1 is installed to the upper end of one of the supports 9 with 6 threaded holes through screws 4; after installation, the tapered pin 3 is installed in the pin holes of the two supports 9 to connect the support 9 with the base plate 2 to prevent the support 9 from being displaced or loosened during use; the support 9 is fixed to the base plate 2 by screws 4; the pin shaft 6 passes through the circular hole at the upper end of the support 9 to connect the bearing 5, washer 8 and nut 7; the lifting ring 10 is installed on the two long slot holes of the base plate 2.

[0033] The method of using the detection support device for thin-walled cylindrical parts of the utility model is as follows:

[0034] When inspecting parts, the use position of the inspection device can be moved at any time according to needs through the lifting ring 10. The part to be inspected is placed above the support body 9 and the bearing 5, and one end is aligned with the positioning block 1 to play an axial positioning role. During the inspection process, the part to be inspected needs to be rotated by external force. The bearing 5 is a driven device. When the part rotates, the bearing 5 can drive the part to be inspected to rotate, solving the problem of inspecting the wall thickness, roundness, straightness and other dimensions of the part.
