Description

Technical Field

[0001] This utility model relates to the field of testing equipment, and in particular to an easily adjustable auxiliary device for testing cylinders. Background Technology

[0002] Cylindrical bodies with circular or elliptical cross-sections are widely used in the aerospace field. These bodies have thin walls and are typically used as components in rocket pipelines or combustion chambers. The manufacturing precision required for these bodies is extremely high. Therefore, comprehensive parameter testing is necessary for such thin-walled bodies to ensure that they meet quality requirements.

[0003] Traditional mechanical inspection tools can no longer meet the inspection needs of cylinders. Therefore, with social development, a method for automatically detecting cylinder errors has emerged. This inspection method involves setting up a reference coordinate system around the cylinder, which includes multiple reference marks around the cylinder. Multi-angle photos are then taken by scanning and the photos are transmitted back to the central control system. The central control system fits a three-dimensional model of the cylinder based on the positional relationship between the cylinder and the various reference marks on the coordinate system in the multiple photos, and derives various parameters of the cylinder based on the three-dimensional model.

[0004] To facilitate the aforementioned cylinder testing steps, the cylinder to be tested needs to be stably placed on an auxiliary device. The auxiliary device designed by the applicant includes a base and multiple spaced support frames on the base. Each support frame has two symmetrically arranged support seats. To accommodate cylinders of different lengths and diameters, each support frame is slidably connected to the base along the length of the cylinder. Simultaneously, along the width of the cylinder, the support frames have multiple spaced screw holes, and the support seats are locked into the corresponding screw holes with screws. When the length of the cylinder changes, the support frames can be manually slid to adjust the support position of the support seats. When the diameter of the cylinder changes, the support on each support frame can be removed and reinstalled at another screw hole to adjust the support space between the two support frames. However, this design has shortcomings. For example, when the length of the cylinder changes, the operator needs to manually control each support frame to slide to the predetermined position. When the diameter of the cylinder changes, the operator needs to remove the screws on each support frame and then lock the screws into the corresponding screw holes after the support frame has moved to the predetermined position. The adjustment process requires repeated removal and installation of screws, which is slow and affects the testing efficiency of cylinders of different specifications.

[0005] Therefore, it is necessary to develop an easily adjustable auxiliary device for cylinder inspection that can quickly adjust the position of the support frame and the support seat when the length and diameter of the cylinder change, thereby improving the inspection efficiency of cylinders of different specifications. Summary of the Invention

[0006] This utility model provides an easily adjustable auxiliary device for cylinder inspection. By setting a length adaptation adjustment component that adapts to changes in cylinder length and a cylinder diameter adaptation adjustment component that adapts to changes in cylinder outer diameter on the base, the positions of the support frame and the support seat can be quickly adjusted into place when inspecting cylinders of different lengths and outer diameters, thereby improving the inspection efficiency of cylinders.

[0007] The technical solution of this utility model is implemented as follows:

[0008] An easily adjustable cylinder detection auxiliary device includes:

[0009] Base;

[0010] Multiple support modules, each support module including a support frame slidably connected to the upper end of the base along the length direction of the base, and two support seats symmetrically arranged on each support frame along the width direction of the base, each support seat slidably connected to the upper end of the support frame along the width direction of the base;

[0011] A length adaptation adjustment component is disposed between each support frame and the base, including a first drive component and a first transmission component. The first transmission component includes a rack disposed on one of the support frame and the base, and a rotating gear disposed on the other of the support frame and the base. The rotating gear meshes with the rack. The first drive component can drive the rotating gear to rotate so as to link the support frame to slide along the length direction of the base and stop at a predetermined position.

[0012] The cylinder diameter adaptation adjustment assembly is located between the two support seats and the corresponding support frame on the support module. It includes a second drive assembly and a second transmission assembly. The second transmission assembly includes a forward-rotating nut and a reverse-rotating nut respectively located on the two support seats. A forward-rotating screw and a reverse-rotating screw are screwed onto the forward-rotating nut and the reverse-rotating nut respectively. The second drive assembly can drive the forward-rotating screw and the reverse-rotating screw to rotate simultaneously, so as to link the two support seats to move closer or further away from each other along the width direction of the base to a predetermined position.

[0013] Preferably, the forward-rotating lead screw and the reverse-rotating lead screw are arranged concentrically and fixedly connected, and the second drive assembly is a second motor that is drivenly connected to one of the forward-rotating lead screw and the reverse-rotating lead screw.

[0014] Preferably, the support frame includes a support platform with two support seats. The lower end of the support platform has an installation space between it and the base. An upper transmission gear is concentrically arranged on the outer end of a forward or reverse screw that is connected to the second motor. The second motor is mounted on the support frame and is located within the installation space. The output end of the second motor is connected to a lower transmission gear, and the upper transmission gear is connected to the lower transmission gear. The top-bottom layout can save installation space and make the structure more compact.

[0015] Preferably, the upper drive gear and the lower drive gear are driven by a chain; or, the upper drive gear and the lower drive gear are driven by meshing.

[0016] Preferably, the support frame is provided with a protective cover that surrounds the upper and lower transmission gears; the protective cover provides protection and prevents safety issues caused by the exposure of the upper and lower transmission gears.

[0017] Preferably, the second drive assembly consists of two second motors respectively connected to the forward-rotating lead screw and the reverse-rotating lead screw.

[0018] Preferably, the rack is mounted on the base, the gear is mounted on the support frame, and the first drive assembly is a first motor that drives the gear to rotate.

[0019] Preferably, the system also includes a base located at the lower end of the base, which is rotatably connected to the base via a pivot. A circumferential adjustment component is provided between the base and the base, which can drive the base and multiple support modules to rotate and stop at corresponding positions.

[0020] Preferably, the circumferential adjustment assembly includes a third motor and a fixed gear mounted on the base and concentric with the rotating shaft. The output end of the third motor is connected to an output gear mounted on the lower end of the base. The output gear meshes with the fixed gear. When the third motor is working, the output gear rotates on its own while rotating around the outer circumference of the fixed gear.

[0021] Preferably, each of the two supports on each support frame includes a supporting ramp, and a V-shaped supporting area is formed between the two supporting ramps; when the two supports move closer or further away from each other along the width direction of the base to a predetermined position, the forward-rotating screw and the reverse-rotating screw respectively form a self-locking mechanism with the forward-rotating nut and the reverse-rotating nut, so that the size of the V-shaped supporting area remains unchanged; preventing the supports from moving when subjected to the pressure of the cylindrical workpiece.

[0022] The beneficial effects of this utility model, which adopts the above technical solution, are as follows:

[0023] This invention, by setting a length adaptation adjustment component to adapt to changes in cylinder length and a cylinder diameter adaptation adjustment component to adapt to changes in cylinder outer diameter on the base, allows for adjustment of the support position of the support frame in the cylinder length direction and the left and right support positions of the support seat on the support frame when the length and outer diameter parameters of the cylinder to be tested change. This eliminates the need for the operator to manually push the support frame or repeatedly disassemble and assemble the screws used to tighten the support seat, simplifying the adjustment process of the support frame and support seat on the cylinder. This enables the cylinder testing auxiliary device to adapt to cylinders with different parameters, improving the efficiency of cylinder testing.

[0024] The support frame is driven by a screw and nut structure, which moves the two supports closer or further apart. After the distance between the two supports is adjusted, the screw and nut can form a self-locking structure to prevent the supports from moving to the left or right when subjected to pressure from the cylinder.

[0025] The support frame and the base are connected by a gear and rack transmission. The gear is driven to rotate by a first motor. When the support frame is adjusted to a predetermined position, the first motor connected to the gear can be switched to a non-working state, so that the gear can no longer rotate, thus limiting the relative movement between the rack and the gear and preventing the support frame from sliding accidentally.

[0026] The second motor is installed in the mounting space formed between the support platform and the base, and transmits the driving force to the forward and reverse screws through the transmission connection between the upper and lower transmission gears, making full use of the space on the detection auxiliary device and making the entire device compact.

Detailed Implementation

[0033] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0035] The specific embodiments of this utility model are as follows:

[0036] Example 1: As Figure 1-5 As shown, this embodiment provides an easily adjustable cylinder detection auxiliary device, including:

[0037] Base 1; Base 1 is a frame structure and serves as a support for the detection auxiliary device; Multiple reference marker rods 7 with front and rear spacing are provided on both sides of the base 1. The reference marker rods 7 can be attached with special reference stickers to facilitate the detection scanning equipment to model the cylinder.

[0038] Multiple support modules are provided, each including a support frame 2 slidably connected to the upper end of the base 1 along the length direction of the base 1, wherein a sliding seat 2a is connected to the lower end of the support frame 2, and a guide rail 11 extending along the length direction of the cylinder is provided at the upper end of the base 1, and the sliding seat 2a is slidably connected to the guide rail 11; two support seats 21 are symmetrically arranged on each support frame 2 along the width direction of the base 1, and each support seat 21 is slidably connected to the upper end of the support frame 2 along the width direction of the base 1; a sliding mounting seat is provided at the lower end of the support seat 21, and a guide rail perpendicular to the length direction of the cylinder is provided at the upper end of the support frame 2, and the sliding mounting seat is slidably connected to the guide rail;

[0039] A length adaptation adjustment assembly is disposed between each support frame 2 and the base 1, including a first drive assembly and a first transmission assembly. The first transmission assembly includes a rack 12 disposed on one of the support frame 2 and the base 1, and a rotating gear 31 disposed on the other of the support frame 2 and the base 1. The rotating gear 31 meshes with the rack 12. The first drive assembly can drive the rotating gear 31 to rotate, so as to link the support frame 2 to slide along the length direction of the base 1 and stop at a predetermined position. When the length of the cylinder to be detected changes, the first drive assembly can drive the support frame 2 to slide, so that the support seat 21 supports the cylinder of the corresponding length.

[0040] The cylinder diameter adaptation adjustment component is located between the two support seats 21 on the support module and the corresponding support frame 2. It includes a second drive component and a second transmission component. The second transmission component includes a forward-rotating nut 22 and a reverse-rotating nut 22a respectively disposed on the two support seats 21. A forward-rotating screw 23 and a reverse-rotating screw 23a are screwed onto the forward-rotating nut 22 and the reverse-rotating nut 22a respectively. When the outer diameter of the cylinder to be tested changes, the second drive component can drive the forward-rotating screw 23 and the reverse-rotating screw 23a to rotate simultaneously, so as to move the two support seats 21 closer to or further away from each other along the width direction of the base 1 to a predetermined position. The entire cylinder detection auxiliary device can adjust the support position of the support frame 2 and the support seats 21 according to the changes in the length and outer diameter of the cylinder, without the need for manual adjustment or repeated disassembly and assembly of screws, simplifying the adjustment process and improving detection efficiency.

[0041] Furthermore, to ensure synchronous rotation of the forward-rotating lead screw 23 and the reverse-rotating lead screw 23a, in this embodiment, the forward-rotating lead screw 23 and the reverse-rotating lead screw 23a are concentrically arranged and fixedly connected. Specifically, one end of the forward-rotating lead screw 23 and one end of the reverse-rotating lead screw 23a are concentrically fixedly connected through a coupling. The upper end of the support frame 2 is provided with two bearing seats 27. The unthreaded part of the other end of the forward-rotating lead screw 23 and the threaded part of the other end of the reverse-rotating lead screw 23a are rotatably connected to the corresponding bearing seats 27. The second drive assembly is a second motor 4 that is drivenly connected to one of the forward-rotating lead screw 23 and the reverse-rotating lead screw 23a. In this embodiment, the second motor 4 is drivenly connected to the forward-rotating lead screw 23. In this way, only one second motor 4 is needed to drive the forward-rotating lead screw 23 and the reverse-rotating lead screw 23a to rotate synchronously, so that the two support seats 21 move closer or further away from each other synchronously.

[0042] Furthermore, if the output end of the second motor 4 is directly connected to the forward-rotating lead screw 23, it would increase the width of the entire cylinder detection auxiliary device, occupy too much space, and be structurally unreasonable. Therefore, in this embodiment, the second motor 4 is installed in a vertically spaced arrangement. Specifically, the support frame 2 includes a support platform with two support seats 21. The lower end of the support platform and the base 1 have an installation space 24. The outer end of the forward-rotating lead screw 23 or the reverse-rotating lead screw 23a, which is connected to the second motor 4, is concentrically provided with an upper transmission gear 26. The motor base 4 is provided in the installation space 24. 1. The second motor 4 is mounted on the support frame 2 and on the motor base 41 within the installation space 24. The output end of the second motor 4 is connected to the lower transmission gear 26a, and the upper transmission gear 26 is connected to the lower transmission gear 26a in a transmission connection. There are many ways to connect the transmission, such as the upper transmission gear 26 and the lower transmission gear 26a being driven by a chain 25; or the upper transmission gear 26 and the lower transmission gear 26a being meshed in a transmission. In this embodiment, the chain 25 is preferred as the transmission component. This design makes full use of the installation space 24 between the support platform and the base 1, optimizes the layout, and makes the structure more compact.

[0043] Furthermore, to prevent safety issues caused by the exposed upper drive gear 26, lower drive gear 26a, and chain 25, the support frame 2 is provided with a protective cover 8 that surrounds the upper drive gear 26 and lower drive gear 26a. The protective cover 8 is a protective metal cover that can prevent safety issues caused by the exposed upper drive gear 26 and lower drive gear 26a, and can also prevent dust or debris from adhering to the upper drive gear 26, lower drive gear 26a, and chain 25.

[0044] Furthermore, the rack 12 in the length adaptation adjustment component is mounted on the base 1, and the gear 31 is mounted on the support frame 2. The first drive component is a first motor 3 that drives the gear 31 to rotate. When the first motor 3 is not working, it can also form a self-locking effect on the gear 31. Specifically, the gear 31 is driven to rotate by the first motor 3. When the support frame 2 is adjusted to the predetermined position, the first motor connected to the gear 31 can switch to a non-working state, so that the gear 31 can no longer continue to rotate, restricting the relative movement between the rack 12 and the gear 31, and preventing the support frame 2 from sliding accidentally.

[0045] Furthermore, to facilitate inspection by the scanning equipment, the cylinder inspection auxiliary device also includes a base 6 located at the lower end of the base 1. The base 6 is rotatably connected to the base 1 via a rotating shaft. A circumferential adjustment component is provided between the base 6 and the base 1. The circumferential adjustment component can drive the base 1 and multiple support modules to rotate and stop at corresponding positions, facilitating the inspection and scanning equipment to inspect the cylinder. The circumferential adjustment component includes a third motor 5 and a fixed gear 61 located on the base 6 and concentric with the rotating shaft. The output end of the third motor 5 is connected to an output gear 51 located at the lower end of the base 1. The output gear 51 meshes with the fixed gear 61. When the third motor 5 is working, the output gear 51 rotates on its own while rotating around the outer circumference of the fixed gear 61. The operator does not need to manually drive the base 1 to rotate; only the output gear 51 needs to be driven by the third motor 5, further improving inspection efficiency.

[0046] Furthermore, to provide stable support for the cylinder to be tested, the structure of the support seat 21 is as follows: each of the two support seats 21 on each support frame 2 includes a support slope, and a V-shaped support area is formed between the two support slopes; after the cylinder is placed on the two support seats 21, it will form a horizontal component force on the two V-shaped support surfaces. Therefore, the screw and nut structure adopted in this embodiment can also prevent the two adjusted support seats 21 from moving away from each other due to the downward pressure of the cylinder. Specifically, when the two support seats 21 move closer or further away from each other to a predetermined position along the width direction of the base 1, the forward screw 23 and the reverse screw 23a form a self-locking mechanism with the forward nut 22 and the reverse nut 22a, respectively, so that the size of the V-shaped support area remains unchanged; preventing the support seat 21 from moving after being subjected to the downward pressure of the cylindrical workpiece.

[0047] Example 2: This example differs from the above examples in that the structure of the second drive assembly is different. In this example, the forward-rotating lead screw 23 and the reverse-rotating lead screw 23a are not fixedly connected (not shown), but are in an independent state. The second drive assembly consists of two second motors 4 that are respectively driven and connected to the forward-rotating lead screw 23 and the reverse-rotating lead screw 23a. The two second motors 4 can drive the two support seats 21 to move respectively, achieving the same effect as in the above examples.

[0048] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
