Description

Technical Field

[0001] The utility model relates to the field of detection equipment, in particular to a cylinder auxiliary detection device. Background Art

[0002] Cylinders with circular or elliptical cross-sections are widely used in the aviation field. These cylinders have thin walls and require extremely high manufacturing precision. They can be used as components in rocket pipelines or combustion chambers. Therefore, comprehensive error detection is required for such processed thin-walled cylinders.

[0003] The traditional inspection method relies on inspectors to use inspection tools to inspect the various form and position tolerances of the cylinder to determine whether the errors of the processed cylinder meet the standards; this inspection method is inefficient, and the inspection tools need to contact the surface of the cylinder, and the cylinder is often scratched, missed, and incorrectly inspected. Therefore, with the development of society, a method that can automatically detect cylinder errors has emerged. This inspection method sets up a reference coordinate system around the cylinder. The reference coordinate system includes multiple reference marks surrounding the workpiece, and then takes photos from multiple angles by scanning. The photos are then transmitted back to the main control system. The main control system will fit a three-dimensional model of the cylinder based on the positional relationship between the cylinder and the reference marks on the coordinate system in the multiple photos, and measure the inner diameter, roundness, and other dimensional data of the cylinder based on the three-dimensional model.

[0004] Therefore, it is necessary to develop an auxiliary device for setting reference marks. The applicant's idea is that the auxiliary device should be provided with a support component for installing the reference point, and the support component is mounted with a carrier for setting the reference mark. The reference mark is usually a calibration sticker that can be recognized by the camera and the master control system; Figure 9 In the displayed support component, by sticking multiple calibration stickers on the corresponding carrier, a three-dimensional reference coordinate system can be established around the cylinder; however, the difficulty in developing this equipment lies in: when the camera is shooting, since the multiple calibration sticker cylinders surround the cylinder and remain motionless, the support component needs to remain fixed, but this will make the position of the support component unadjustable, making it difficult to load the cylinder onto the auxiliary detection device, affecting detection efficiency. Summary of the Invention

[0005] In order to solve the above-mentioned technical problems, the utility model provides a cylinder auxiliary detection device, which hinges any two adjacent longitudinal support rods to form a hinged end, so that the upper support section can be flipped outward when the cylinder is loaded, so as to facilitate the placement of the cylinder on the supporting assembly; when the cylinder is inspected, the upper support section can be closed inward and the cylinder is surrounded by multiple reference calibration rods; it meets the detection requirements of the auxiliary detection device and also improves the detection efficiency of the cylinder.

[0006] The technical solution of the present utility model is achieved as follows:

[0007] A cylinder auxiliary detection device includes a plurality of auxiliary detection components spaced apart from each other in front and back, the auxiliary detection components including a base, a supporting component for supporting the cylinder, and calibration modules symmetrically arranged on the left and right sides of the supporting component, the calibration module including a support component arranged on the base, the support component including a plurality of longitudinal support rods connected in the longitudinal direction, a transverse support rod extending inwardly connected to the top longitudinal support rod, and reference calibration rods extending in the front and back for setting reference marks on both the transverse support rods and the longitudinal support rods; a connecting end is formed between every two adjacent longitudinal support rods, and any one of the plurality of connecting ends is a hinged end; the hinged end divides the plurality of longitudinal support rods into an upper support section and a lower support section;

[0008] The auxiliary detection device has a loading state and a detection state. When the auxiliary detection device is in the loading state, the multiple upper support segments can be flipped outward through the hinged end so that the cylinder can be placed on multiple front and rear spaced support components. When the auxiliary detection device switches to the detection state, the multiple upper support segments are closed inward through the hinged end so that the cylinder is surrounded by multiple reference calibration rods.

[0009] Preferably, a base is also included, and multiple bases can slide on the base in the front-to-back direction and stay at the corresponding position to adjust the supporting position of the supporting component into place; it can adapt to cylinders of different lengths and avoid the unobstructed detection part on the cylinder.

[0010] Preferably, the base is provided with a linear guide rail extending forward and backward, the base is provided with a connecting seat slidably connected to the linear guide rail, and the connecting seat is installed with a linear guide rail clamp for locking and unlocking the connecting seat; the linear guide rail clamp can control the sliding locking and unlocking of the base, so that the base slid into place remains stable.

[0011] Preferably, a positioning assembly is provided on the base, which includes a positioning seat slidably connected to the base, and the positioning seat is provided with a telescopic positioning rod for positioning the end of the cylinder; when the cylinder is placed on the supporting assembly, the telescopic positioning rod extends upward and positions the end of the cylinder, and when the positioning is completed, the telescopic positioning rod retracts downward to avoid blocking the cylinder.

[0012] Preferably, the supporting assembly is a V-shaped supporting seat, and a bilaterally symmetrical V-shaped surface is formed on the upper end of the V-shaped supporting seat; the V-shaped supporting seat can support the cylinder and keep the cylinder stable in the left and right directions.

[0013] Preferably, reference calibration rods for surrounding the bottom of the cylinder are symmetrically provided on the V-shaped support seat along the left and right directions; thereby, multiple reference calibration rods surround the cylinder in all directions, making the reference coordinate system formed around the cylinder more accurate.

[0014] Preferably, the V-shaped supporting seat includes two left-right symmetrical supporting supports, each of which is provided with a through hole, and the base is provided with a plurality of screw holes spaced left and right and corresponding to the positions of the through holes. The through holes on the supporting support cooperate with the screw holes at different positions to change the distance between the two supporting supports; to support cylinders with different outer diameters.

[0015] Preferably, a control assembly is provided on the hinged end, which includes a locking screw and a butterfly nut with threaded matching, and corresponding avoidance holes are provided in the two adjacent longitudinal support rods at the hinged end; when the auxiliary detection device is in the detection state, the locking screw passes through the avoidance hole and locks the closed upper support section through the butterfly nut; when the auxiliary detection device is in the loading state, the butterfly nut is loosened and the locking screw is pulled out so that the upper support section can be flipped outward.

[0016] Preferably, the transverse support rod is hinged to the topmost longitudinal support rod, and the auxiliary detection device also has a disassembled state. When the auxiliary detection device is in the disassembled state, the transverse support rods on the left and right sides are flipped outward to facilitate the removal of the cylinder from the supporting assembly. When the auxiliary detection device is in the detection state, the transverse support rods on the left and right sides are closed inward to a horizontal state.

[0017] Preferably, it also includes a handwheel bolt, which has a handwheel and a threaded section. A threaded hole is provided on the top longitudinal support rod, and a through-hole corresponding to the threaded hole is provided on the transverse support rod. When the auxiliary detection device is in the detection state, the threaded section passes through the through-hole and is screwed into the threaded hole to lock the closed transverse support rod. When the auxiliary detection device is in the disassembly state, the handwheel is turned to make the threaded section disengage from the threaded hole to flip the transverse support rod outward.

[0018] The beneficial effects of the utility model using the above technical solution are:

[0019] The utility model divides the calibration module into an upper support section and a lower support section through a hinged end, so that the upper support sections on the left and right sides can be flipped outward through the hinged end when the cylinder is loaded, and make room for loading the cylinder. After the cylinder is loaded into place, the upper support sections on the left and right sides can be closed inward, so that multiple reference calibration rods surround the cylinder and form a reference coordinate system around the cylinder, which meets the detection requirements of the auxiliary detection device and improves the detection efficiency of the cylinder.

[0020] Compared with loading the cylinder onto the supporting assembly, the left and right swing amplitude is smaller when removing the cylinder from the supporting assembly, and the operation is also less difficult. Therefore, the transverse support rod is also hingedly connected to the top longitudinal support rod. When disassembling the cylinder, there is no need to flip the entire upper support section outward significantly. It is only necessary to flip the transverse support rod outward to make a smaller opening for the cylinder to pass upward. The design is ingenious, which can improve the efficiency of cylinder disassembly and further improve the detection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0032] In the following description, many specific details are set forth to facilitate 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.

[0033] The specific implementation methods of the utility model are as follows:

[0034] like Figure 1-8 As shown, this embodiment provides a cylinder auxiliary detection device, including a plurality of auxiliary detection components spaced front and back, the auxiliary detection component including a base 2, a supporting component 6 for supporting the cylinder is provided on the base 2, and a calibration module 4 is symmetrically arranged on the left and right sides of the supporting component 6, the calibration module 4 includes a support component provided on the base 2, the support component includes a plurality of longitudinal support rods 3 connected in the longitudinal direction, the top longitudinal support rod 3 is connected to a transverse support rod 5 extending inward, the transverse support rod 5 and the longitudinal support rod 3 are both provided with a reference calibration rod 41 for setting a reference mark and extending forward and backward; the transverse support rod 5 and the longitudinal support rod 3 are both pre-connected with a U-shaped seat 42 by screws, and the U-shaped seat 42 has a U The reference calibration rod 41 is located in the U-shaped groove and is locked with the U-shaped seat 42 by screws; the reference calibration rod 41 is used to stick multiple calibration stickers to facilitate the scanning device 8 near the cylinder auxiliary detection device to take multiple photos; in this embodiment, in order to facilitate the sticking of calibration stickers, the reference calibration rod 41 is set to a prismatic structure, and its cross-sectional shape is polygonal; and in order to make the reference calibration rod 41 lighter, the reference calibration rod 41 is an aluminum rod; a connecting end is formed between every two adjacent longitudinal support rods 3, and any one of the multiple connecting ends is a hinged end; the hinged end divides the multiple longitudinal support rods 3 into an upper support section 4a and a lower support section 4b; the upper support section 4a and the lower support section 4b are hinged by a rotating support shaft 33;

[0035] The auxiliary detection device has a loading state and a detection state. When the auxiliary detection device is in the loading state, the multiple upper support segments 4a can be flipped outward through the hinged end so that the cylinder can be placed on multiple front and rear spaced support assemblies 6. When the auxiliary detection device is switched to the detection state, the multiple upper support segments 4a are closed inward through the hinged end so that the cylinder is surrounded by multiple reference calibration rods 41.

[0036] Furthermore, each two adjacent auxiliary reference components have multiple sets of corresponding front and rear reference calibration rods 41. In order to enable the scanning device 8 to fully scan and photograph the entire cylinder extending front and back, the corresponding two reference calibration rods 41 are staggered front and back, so that the cylinder is surrounded by multiple reference calibration rods 41 in the length direction, so that there will be no empty areas for shooting, thereby avoiding the problem of missing reference points when the scanning device 8 is taking pictures.

[0037] Furthermore, the lengths of the cylinders to be inspected are different, and some cylinders have various processed holes to be inspected. In order to ensure the accuracy of the scanning, the supporting component 6 cannot be blocked by these holes to be inspected. Therefore, in order to meet the inspection needs of each cylinder, the cylinder auxiliary inspection device also includes a base 1, and multiple bases 2 can slide on the base 1 in the front-to-back direction and stay at the corresponding position to adjust the support position of the supporting component 6 into place; the multiple supporting components 6 adjusted into place can adapt to cylinders of different lengths, and can also avoid the unblockable inspection holes on the cylinder. The design is ingenious and kills two birds with one stone.

[0038] Furthermore, the sliding connection between the base 2 and the base 1 is as follows: a linear guide rail extending forward and backward is provided on the base 1, a connecting seat 21 slidably connected to the linear guide rail is provided on the base 2, and a linear guide rail clamp 12 for locking and unlocking the connecting seat 21 is installed on the connecting seat 21; the linear guide rail clamp 12 can control the sliding locking and unlocking of the base 2, so that the base 2 that slides into place remains stable; specifically, if Figure 4 As shown, the linear guide rail clamp 12 includes a first clamping block 122 and a second clamping block 123 with two intervals at the bottom, and a guide groove that slides with the linear guide rail 11 is formed between the first clamping block 122 and the second clamping block 123. The first clamping block 122 and the second clamping block 123 are respectively provided with two spiral holes with opposite thread rotation directions, and a screw rod 124 is fitted in the spiral hole. The outer end of the screw rod 124 is connected to a handle 121. When the base 2 slides, the linear guide rail clamp 12 can slide together with the connecting seat 21. When the base 2 slides into place, the handle 121 is rotated to make the first clamping block 122 and the second clamping block 123 approach each other and clamp the linear guide rail 11 to keep the base 2 fixed in the corresponding position.

[0039] Furthermore, when workers load the cylinders by hoisting, it is difficult to place multiple cylinders in the same supporting position. Therefore, a positioning assembly is provided on the base 1, which includes a positioning seat 71 slidably connected to the base 1, and a telescopic positioning rod 7 for positioning the end of the cylinder is provided on the positioning seat 71; a linear guide fixture 12 is also connected to the bottom of the positioning seat 71 to control the position of the telescopic positioning rod 71; a sleeve is provided at the upper end of the positioning seat 71, and the telescopic positioning rod 7 is inserted into the sleeve and is locked and fixed by a set screw 72 with a handwheel; a sleeve is also provided on the side of the base 1 There is a measuring ruler 13 with specific scales on it. When the cylinder is placed on the supporting assembly 6, the telescopic positioning rod 7 extends upward and acts as a position ruler. The worker can adjust the position of the telescopic positioning rod 7 and, in combination with the scale on the measuring ruler 13, make the position of the end of the cylinder deviate from the predetermined position by no more than 30 mm, thereby achieving the purpose of positioning the end of the cylinder. When the positioning is completed, the telescopic positioning rod 7 retracts downward to avoid blocking the cylinder, ensuring that the scanning accuracy of the scanning device 8 will not be affected by the existence of the telescopic positioning rod 7 when taking pictures.

[0040] Further, if Figure 5 As shown, in order to ensure that the cylinder remains stable during testing, the supporting assembly 6 is a V-shaped supporting seat, and a left-right symmetrical V-shaped surface is formed on the upper end of the V-shaped supporting seat. The V-shaped surface can support the cylinder and keep the cylinder stable in the left and right directions. In order to protect the outer surface of the cylinder when loading the cylinder, a supporting block 62 for contacting the cylinder is installed on the V-shaped surface. The supporting block 62 is made of nylon or plastic with lower hardness and will not cause bumps or scratches on the outer surface of the cylinder.

[0041] Furthermore, in order to ensure the accuracy of photo scanning, reference calibration rods 41 for surrounding the bottom of the cylinder are symmetrically provided on the V-shaped support seat in the left and right directions; thereby, multiple reference calibration rods 41 surround the cylinder in all directions, making the reference coordinate system formed around the cylinder more accurate.

[0042] Furthermore, in order to enable the auxiliary detection device to detect cylinders with different outer diameters, the V-shaped supporting seat includes two left-right symmetrical supporting supports 61, the supporting supports 61 are provided with through holes, and the base 2 is provided with multiple screw holes 22 spaced left and right and corresponding to the positions of the through holes. The through holes on the supporting supports 61 cooperate with the screw holes 22 at different positions to change the distance between the two supporting supports 61; the distance between the two supporting supports 61 is made to correspond to the outer diameter of the cylinder to adapt to cylinders with different outer diameters.

[0043] Further, if Figure 6-8 As shown, in order to facilitate the control of the upper support section 4a and switch the auxiliary detection device between the loading state and the detection state, a control component is provided on the hinged end, and the control component includes a locking screw 31 and a butterfly nut 32 with threaded matching, and corresponding avoidance holes are provided in the two adjacent longitudinal support rods 3 at the hinged end; when the auxiliary detection device is in the detection state, the locking screw 31 passes through the avoidance hole and locks the closed upper support section 4a through the butterfly nut 32; when the auxiliary detection device is in the loading state, the butterfly nut 32 is loosened and the locking screw 31 is pulled out, so that the upper support section 4a can be flipped outward.

[0044] Furthermore, when workers load the cylinder by hoisting, they need to hoist the cylinder from the discharge point to the vicinity of the detection device. The cylinder is prone to swinging left and right, and hoisting is difficult. However, when the cylinder needs to be unloaded after inspection, since the cylinder remains stable on the support assembly 6, it only needs to be hoisted vertically from bottom to top, and the swing amplitude of the cylinder is small. Therefore, in this embodiment, the transverse support rod 5 is hinged to the topmost longitudinal support rod 3 to adapt to the disassembly state of the auxiliary detection device. The transverse support rod 5 and the topmost longitudinal support rod 3 are also hinged by the rotating support shaft 33; when the auxiliary detection device is in the detection state, the transverse support rods 5 on both sides are closed inward to a horizontal state; when the auxiliary detection device is in the disassembly state, the transverse support rods 5 on both sides are flipped outward to facilitate the removal of the cylinder from the support assembly 6, without the need to flip the entire upper support section 4a outward, thereby reducing the difficulty of operation.

[0045] Furthermore, in order to facilitate the control of the transverse support rod 5 and switch the auxiliary detection device between the loading state and the disassembly state, the auxiliary detection device also includes a handwheel bolt 34. The handwheel bolt 34 has a handwheel and a threaded section. A threaded hole is provided on the topmost longitudinal support rod 3, and a through-hole corresponding to the threaded hole is provided on the transverse support rod 5. When the auxiliary detection device is in the detection state, the threaded section passes through the through-hole and is screwed into the threaded hole to lock the closed transverse support rod 5. When the auxiliary detection device is in the disassembly state, the handwheel is turned to make the threaded section disengage from the threaded hole to flip the transverse support rod 5 outward.

[0046] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
