DETAILED DESCRIPTION

[0032] The present application will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0033] Reference Figures 1 to 6 As shown in the figure, a cylinder size detection device includes a trestle assembly 1, a bearing assembly 2, a front limiting assembly 3, a rear limiting assembly 4, a paint spraying assembly 5, and a detection assembly 6.

[0034] The platform assembly 1 is the main body of the device, used to securely hold the other components. It is equipped with a support assembly 2, a front stop assembly 3, a rear stop assembly 4, a paint assembly 5, and a detection assembly 6. A cylinder mounting area is formed on the support assembly 2, upon which a cylinder 7 can be placed.

[0035] The front limit assembly 3 is located at the front end of the cylinder mounting area, while the rear limit assembly 4 is located at the rear end of the cylinder mounting area. The rear limit assembly 4 is movably mounted on the platform assembly 1 and moves between a restricted position and a released position. When the cylinder 7 is placed on the support assembly 2, the rear limit assembly 4 moves from the released position to the restricted position, clamping the cylinder 7 between the front and rear limit assemblies. When the rear limit assembly 4 moves from the restricted position to the released position, the cylinder 7 is released from the restricted position, allowing it to be removed from the support assembly 2.

[0036] The inspection assembly 6 is used to inspect the dimensions of the cylinder 7 to determine whether the cylinder 7 is qualified. The paint spraying assembly 5 can be installed on the platform assembly 1 or on the rear limit assembly 4 to move with it. The paint spraying assembly 5 is positioned toward the cylinder. If the data obtained by the inspection assembly 6 determines that the dimensions of the cylinder 7 are unqualified, the paint spraying assembly 5 will spray paint on the cylinder 7 to mark it.

[0037] The platform assembly 1 comprises a platform frame 101, universal pulleys 102, legs 103, lifting lugs 104, and a top plate. The platform frame 101 is a rectangular parallelepiped constructed from welded rectangular tubes. Universal pulleys 102 are installed at each of the four legs of the platform frame 101, facilitating the movement of the entire device. The top plate is located on top of the platform frame 101, upon which all other components are mounted and secured.

[0038] The four feet of the platform frame 101 are equipped with vertically adjustable legs 103. The legs 103 are used to fix the platform frame 101 to the ground. The vertical position is adjusted by screws passing through oblong holes, which can meet the requirements of fine-tuning the fixed height position. The four shoulders of the platform frame 101 are equipped with lifting ears 104 to facilitate lifting the entire device.

[0039] The bearing assembly 2 includes a bearing base plate 201, a bearing bracket 202 and a handle 203. The bearing base plate 201 is detachably mounted on the top plate of the platform assembly 1 by screws. By replacing the bearing base plate 201 and the bearing bracket 202 of different specifications, the cylinder bodies 7 of different specifications can be placed.

[0040] Support brackets 202 are fixed to either side of the support base 201. The inclined surfaces of the two support brackets 202 face each other, forming a V-shaped support structure capable of supporting the cylindrical cylinder 7. Two sets of support brackets 202 are arranged on the support base 201, front and rear, ensuring stable placement of the cylinder 7 and meeting the requirements of large-span installation. Handles 203 are welded to both sides of the support base 201 for easy handling.

[0041] The front stop assembly 3 is formed with an L-shaped stop angle or stop step, and the vertical stop surface of the stop angle or stop step is used to block the front end of the cylinder 7. The front stop assembly 3 is detachably mounted on the platform assembly 1 or the supporting assembly 2 by screws, and is specifically fixed to the top plate. By replacing the front stop assembly 3 of different specifications, it can meet the limit blocking requirements of cylinders 7 of different specifications.

[0042] The front limit assembly 3 comes in two forms: an integral limit block 301 or a split limit block 302. The integral limit block 301 is manufactured as a single piece. The split limit block 302 is manufactured in separate pieces, including a horizontal limit block 303 and a vertical limit block 304. The front end of the horizontal limit block 303 is connected to the vertical limit block 304 via screws. The limit angle or limit step can be designed on a single piece or formed by combining two pieces.

[0043] The rear limit assembly 4 includes a slide rail 401, a slider 402, a mounting plate 403, a limit plate 404, and a telescopic cylinder 405. The slide rail 401 is provided on the platform assembly 1 or the supporting assembly 2. Specifically, two parallel slide rails 401 are provided and fixed to the top plate. The slide rails 401 are provided with sliding sliders 402. The two sliders 402 are respectively connected to the two sides of the mounting plate 403 to achieve horizontal sliding movement of the mounting plate 403.

[0044] Mounting plate 403 is fixedly connected to one end of a telescopic cylinder 405, the other end of which is fixedly connected to the platform assembly 1 or the supporting assembly 2. Specifically, telescopic cylinder 405 is fixed to the top plate. Telescopic cylinder 405 is a pneumatic or hydraulic cylinder, and the power of telescopic cylinder 405 enables mounting plate 403 to slide in the front-to-back direction.

[0045] The mounting plate 403 is fixedly connected to the limit plate 404 by screws. The limit plate 404 is an L-shaped structure, and a limit vertical surface is formed on the limit plate 404. When the limit plate 404 slides back and forth following the mounting plate 403, the limit vertical surface contacts the rear end of the cylinder body 7 and pushes the cylinder body 7 until the front end of the cylinder body 7 contacts the front limit assembly 3, thereby clamping the cylinder body 7 and preventing the cylinder body from moving during the size detection process, thereby affecting the accuracy of the final result.

[0046] The paint spray assembly 5 includes an air cylinder 501, a paint bucket 502, and a spray head 503. The air cylinder 501 is fixed to the stop plate 404, and the paint bucket 502 is connected to the air cylinder 501. Air and pressure are supplied to the paint bucket 502 through the air cylinder 501. The paint bucket 502 is fixed to the stop plate 404, and the spray head 503 is connected to the paint bucket 502. The paint inside the paint bucket 502 is sprayed out through the spray head 503.

[0047] The nozzle 503 is also fixed on the limit plate 404 and passes through the limit plate 404. The nozzle 503 is positioned toward the cylinder body. When the cylinder body 7 fails the inspection, the paint is sprayed toward the rear end (bottom surface) of the cylinder body 7 through the nozzle 503 to mark and remind, so as to facilitate subsequent operators to screen defective products.

[0048] The detection assembly 6 includes a robotic arm 601, a contact sensor 602, and an in-position sensor 603. The robotic arm 601 is fixed to the top plate of the platform assembly 1. The end of the robotic arm 601 is provided with a contact sensor 602 (model GT-H10). The robotic arm 601 is preferably a three-axis six-degree-of-freedom robotic arm that can control the contact sensor 602 to move to any position in the cylinder.

[0049] After the cylinder 7 to be inspected is positioned, the robotic arm 601, carrying the contact sensor 602 for inspection, moves to various test points inside and outside the cylinder, where it performs spatial calibration and dimensional inspection. The contact sensor uses low pressure to extend the sensor head's main axis until it contacts the object under test. At this point, the sensor captures the relative distance to the test point. Combined with the robotic arm's movement, the relative spatial coordinates of the test point within the entire device can be calculated.

[0050] The in-position sensor 603 is provided on the top plate of the platform assembly 1 . The in-position sensor 603 is opposite to the cylinder body placement position. The in-position sensor 603 is used to determine whether the cylinder body 7 is placed on the bearing assembly 2 .

[0051] The test bench assembly 1 is equipped with a human-machine interface (HMI) component. The rear limit assembly 4, the paint assembly 5, and the inspection assembly 6 are all electrically connected to the HMI component. This HMI component controls the entire inspection process. The operator can use it to select and configure the cylinder dimensions to be tested, configure test points, initiate the test process, and generate and review test reports.

[0052] The human-computer interaction component also includes a temperature sensor, which can automatically correct the detection results. After collecting data in the early stage, the impact of temperature changes on the detection can be obtained.

[0053] The aforementioned basic examples and their further selected examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed for protection in this application. In this application, each selected example can be arbitrarily combined with any other basic examples and selected examples.

[0054] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
