[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] As Figures 1-5 shown, the technical scheme adopted by the utility model is as follows: a sealing gasket size detection device, including workbench 1, the top of workbench 1 is horizontally slidably provided with grating ruler 4. Grating ruler 4 is also called grating ruler displacement sensor, is the measuring feedback device that utilizes the optical principle of grating, can be used as the detection of linear displacement or angular displacement. Grating ruler 4 is an existing product, and there is also a grating ruler in the patent CN221571316U mentioned in the background art.

[0025] The top surface of workbench 1 is fixedly connected with electric slide rail 2 at one side, and the sliding block is slidably arranged on electric slide rail 2. The working principle of electric slide rail 2 is to drive the sliding block to move linearly on the guide rail by using the motor, and the electric slide rail 2 is an existing product. The top of the sliding block is fixedly connected with the fixed block 3, and one end of the grating ruler 4 is fixedly connected to one side of the fixed block 3. When the sliding block slides on the electric slide rail 2, the fixed block 3 and the grating ruler 4 are driven to move, so that the grating ruler 4 can measure the size.

[0026] The top of workbench 1 is provided with a plurality of centering assemblies along the moving direction of grating ruler 4.

[0027] The centering assembly includes three centering plates 5. The top of workbench 1 is rotatably provided with a gear 7 at each centering assembly. The three centering plates 5 are distributed in a circular array about the gear 7. Each centering plate 5 is rotatably arranged on the top of workbench 1.

[0028] The workbench 1 is internally fixedly connected with a motor 6 at each centering assembly, the output shaft of the motor 6 extends to the top of the workbench 1, and a gear 7 is fixedly sleeved on the output shaft of the motor 6. The motor 6 drives the gear 7 to rotate.

[0029] The end of each centering plate 5 is fixedly sleeved with a circular-arc-shaped rack 8, and the gear 7 is engaged with the corresponding three racks 8. When the gear 7 rotates, it drives the three racks 8 to rotate synchronously.

[0030] The inner part of the end of each centering plate 5 close to the rack 8 is rotatably connected with a fixing rod 9, and each fixing rod 9 is fixedly connected to the top of the workbench 1. The fixing rod 9 is coaxially arranged with the corresponding rack 8. The one end of the centering plate 5 is positioned on the workbench 1 through the fixing rod 9.

[0031] The end of each centering plate 5 away from the rack 8 is arc-shaped, and each centering plate 5 is provided with a scale line 10 for measuring height on one arc-shaped surface away from the rack 8. When the sealing gasket is fixed by the centering plate 5, the height of the sealing gasket can be measured by the scale line 10.

[0032] The center of the top end of the output shaft of each motor 6 is provided with a mark point. Once the center is determined, the diameter of the circle can be obtained by measuring the distance from the center to any point on the circle and then multiplying by two. This method is more accurate and reliable than directly measuring the distance between two points on the circle.

[0033] Working principle:

[0034] In use, the sealing gasket is sequentially sleeved on the three centering plates 5 of the centering assembly, so that the three centering plates 5 are located inside the sealing gasket. The sealing gasket is located on the top of the workbench 1.

[0035] Start the motor 6, and the output shaft of the motor 6 rotates forward. The gear 7 is driven to rotate, the gear 7 drives the three racks 8 to rotate, and the centering plate 5 is driven to rotate. The end of the centering plate 5 rotates on the corresponding fixing rod 9. The end of the centering plate 5 provided with the scale line 10 rotates towards the inner wall of the sealing gasket.

[0036] If the center of the sealing gasket is concentric with the output shaft of the motor 6, the ends of the three centering plates 5 provided with the scale line 10 simultaneously contact the inner wall of the sealing gasket, and then the ends of the three centering plates 5 abut against the inner wall of the sealing gasket to fix the sealing gasket.

[0037] If the center of the sealing gasket is not concentric with the output shaft of the motor 6, the end of one of the centering plates 5 will contact the inner wall of the sealing gasket. When the centering plate 5 continues to rotate, it will push the sealing gasket to move until the ends of the three centering plates 5 abut against the inner wall of the sealing gasket to fix the sealing gasket. At this time, the center of the sealing gasket is the mark point at the top of the output shaft of the motor 6.

[0038] After fixing the multiple sealing gaskets on the centering assembly respectively, the height of the sealing gasket can be detected through the scale line 10.

[0039] The fixed block 3 and the grating ruler 4 are driven to move by the electric sliding rail 2, so that the grating ruler 4 moves to the sealing gasket in sequence, and the diameter of the sealing gasket is measured at the mark point.

[0040] After the grating ruler 4 measures the diameter of one of the sealing gaskets, the grating ruler 4 moves to the next sealing gasket for measurement.

[0041] One of the motors 6 for measuring the size of the sealing gasket is started, the output shaft of the motor 6 is reversed, so that the three centering plates 5 rotate synchronously, the end of the centering plate 5 is away from the inner wall of the sealing gasket, the sealing gasket can be directly moved out, so as to re-place the sealing gasket and continue to detect, so that the other sealing gaskets are removed and installed at the same time of detection, the operation time is saved, and the work efficiency is improved.

[0042] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
