[0002] The inner and outer diameters and concentricity data of the aluminum disk ring are mostly measured using a three-dimensional coordinate measuring machine. When measuring, you need to first place an iron column on the marble table of the three-dimensional coordinate measuring machine, and then place the aluminum disk to be measured on the top of the iron column. The aluminum disk to be measured must completely cover the iron column. At the same time, the contact surface between the aluminum disk and the iron column needs to be fixed with glue to prevent the aluminum disk from offset during measurement. Finally, adjust the aluminum disk to the specified position and start the measurement.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0031] See attached Figure 1 As shown, this embodiment provides a loading and unloading device for measuring aluminum disk rings, including a Y-axis screw slide 2, an X-axis screw slide 3, a first Z-axis screw slide 4, a second Z-axis screw slide 5, a suction cup assembly 6, a tablet press 7 and a measuring base 8. The Y-axis screw slide 2 is fixedly mounted on a marble table 103 of a mobile bridge type three-dimensional coordinate measuring instrument 1 through a fixed frame 12. Among them, the mobile bridge type three-dimensional coordinate measuring instrument 1 is an existing device, which mainly includes a measuring needle device 101, a mobile bridge 102, and a marble table 103.

[0032] The first Z-axis screw slide 4 is longitudinally fixedly installed on the movable end of the Y-axis screw slide 2; when working, the Y-axis screw slide 2 is used to drive the first Z-axis screw slide 4 to move forward and backward; the movable end of the first Z-axis screw slide 4 is installed with a suction cup assembly 6; when working, the first Z-axis screw slide 4 is used to drive the suction cup assembly 6 to rise and fall, and the suction cup assembly 6 is connected to the external negative pressure system through the air guide hose 13. When working, the external negative pressure system provides suction for the suction cup assembly 6, thereby sucking air into the aluminum plate to be tested.

[0033] The X-axis screw slide 3 is fixed on the marble table 103 of the mobile bridge three-dimensional coordinate measuring instrument 1, and the second Z-axis screw slide 5 is longitudinally fixedly installed on the moving end of the X-axis screw slide 3. When working, the X-axis screw slide 3 is used to drive the second Z-axis screw slide 5 to move left and right, and the moving end of the second Z-axis screw slide 5 is fixed with a sheet press 7; the second Z-axis screw slide 5 can drive the sheet press 7 to move up and down.

[0034] In this embodiment, the end of the tablet press 7 is two parallel pressure plates, and the distance between the two pressure plates is greater than the inner diameter of the aluminum plate 11 and smaller than the outer diameter of the aluminum plate 11. This arrangement enables the tablet press 7 to press on both sides of the top of the aluminum plate 11, and the aluminum plate 11 is more stable after being pressed, thereby preventing it from moving during the measurement process. The aluminum plate 11 is in a circular ring shape, as shown in the attached figure. Figure 7 shown.

[0035] The measuring base 8 is cylindrical (see Figure 6 As shown), it is arranged on the top of the marble table 103, which is located between the first Z-axis screw slide 4 and the second Z-axis screw slide 5 and is opposite to the X-axis screw slide 3; wherein, the inner diameter of the measuring base 8 is larger than the inner diameter of the aluminum disk 11, and the outer diameter of the measuring base 8 is smaller than the outer diameter of the aluminum disk 11, so as to avoid interference caused by the measuring base 8 during the measurement of the inner and outer diameters of the aluminum disk 11.

[0036] In this embodiment, the first disk placing base 9 and the second disk placing base 10 are respectively arranged on both sides of the measuring base 8, and the first disk placing base 9 and the second disk placing base 10 are both composed of a base and a column, and the column and the inner diameter of the aluminum disk 11 are clearance-matched. When the device is used, the aluminum disk to be measured is stacked and sleeved on the column of the first disk placing base 9, and the measured aluminum disk is sleeved on the column of the second disk placing base 10 through the Y-axis lead screw slide 2, the first Z-axis lead screw slide 4 and the suction cup assembly 6.

[0037] When the loading and unloading device is working, firstly, the aluminum disc to be measured on the first disc placing base 9 is moved to the top of the measuring base 8 through the cooperation of the Y-axis screw slide 2, the first Z-axis screw slide 4 and the suction cup assembly 6. After the aluminum disc to be measured is placed, the Y-axis screw slide 2 and the first Z-axis screw slide 4 drive the suction cup assembly 6 to reset;

[0038] Then, the tablet press 7 is pressed on the top of the aluminum plate to be tested through the X-axis screw slide 3 and the second Z-axis screw slide 5, and then the mobile bridge type three-dimensional coordinate measuring instrument 1 is started to detect the inner and outer diameters and concentricity of the aluminum plate;

[0039] After the detection is completed, the sheet press 7 is reset through the X-axis screw slide 3 and the second Z-axis screw slide 5, and then the aluminum plate 11 on the measuring base 8 is placed on the column of the second plate placing base 10 through the Y-axis screw slide 2 and the first Z-axis screw slide 4, thus completing the automatic loading and unloading of the aluminum plate.

[0040] See attached Figure 2-3 As shown, the Y-axis lead screw slide 2, the X-axis lead screw slide 3, the first Z-axis lead screw slide 4, and the second Z-axis lead screw slide 5 all include a hollow mounting shell 14, a shell cover 15, a servo motor 16, a lead screw 17, a moving block 18 and a fixed block 19. The shell cover 15 is fixedly installed on the top of the hollow mounting shell 14. The hollow mounting shell 14 and the shell cover 15 are combined to form a hollow shell body with strip openings on the opposite side walls. The servo motor 16 is installed in the inner cavity of the hollow mounting shell 14, and the output end of the servo motor 16 is connected to the lead screw 17 through a coupling. The other end of the lead screw 17 is installed on the inner wall of the hollow mounting shell 14 through a bearing seat. A moving block 18 is installed on the lead screw 17, and a fixed block 19 is connected to the end of the moving block 18. An opening for avoiding the shell cover 15 is opened in the middle of the fixed block 19, and the fixed block 19 and the shell cover 15 are clearance-matched. When the Y-axis screw slide 2, the X-axis screw slide 3, the first Z-axis screw slide 4, and the second Z-axis screw slide 5 are working, the servo motor 16 drives the screw 17 to rotate, and the rotation of the screw 17 drives the moving block 18 and the fixed block 19 to move.

[0041] In this embodiment, the first Z-axis screw slide 4 is longitudinally fixedly installed on the fixed block 19 of the Y-axis screw slide 2, and the second Z-axis screw slide 5 is longitudinally fixedly installed on the fixed block 19 of the X-axis screw slide 3. The suction cup assembly 6 and the sheet press 7 are respectively installed on the fixed blocks 19 of the first Z-axis screw slide 4 and the second Z-axis screw slide 5.

[0042] See attached Figure 4-5 As shown, the suction cup assembly 6 includes an L-shaped mounting plate 61, a hollow threaded sleeve 62, a nut 63, an air guide tube 64, a spring 65, and a suction cup 66. A through hole for avoiding the hollow threaded sleeve 62 is opened on the horizontal plate surface of the L-shaped mounting plate 61; in this embodiment, two groups of through holes are opened on the horizontal plate surface of the L-shaped mounting plate 61, and the hollow threaded sleeve 62 is penetrated through the two through holes. The upper and lower ends of the hollow threaded sleeve 62 are threadedly connected with nuts 63, and the nuts 63 are clamped on both sides of the horizontal plate surface of the L-shaped mounting plate 61 to fix the position of the hollow threaded sleeve 62.

[0043] An air guide tube 64 is retractably inserted in the middle of the hollow threaded sleeve 62, and the upper and lower ends of the air guide tube 64 are respectively connected to the air guide hose 13 and the suction cup 66; wherein, the spacing between the suction cups 66 is larger than the inner diameter of the aluminum plate 11 and smaller than the outer diameter of the aluminum plate 11. This arrangement can prevent the two suction cups 66 from being unable to be adsorbed to the aluminum plate at the same time due to the spacing between the suction cups 66 being too small or too large.

[0044] A limiting step 641 is provided on the upper part of the air guide tube 64, and the bottom of the limiting step 641 abuts against the top of the hollow threaded sleeve 62, so as to limit the air guide tube 64 and prevent the air guide tube 64 from further falling. A hanging platform 642 is provided at the lower part of the air guide tube 64, and a spring 65 is provided on the outer side of the air guide tube 64, and the spring 65 is located between the hanging platform 642 and the hollow threaded sleeve 62.

[0045] When the aluminum disk is adsorbed, the suction cup assembly 6 is pressed onto the aluminum disk, the air guide tube 64 is pressed upward, and the spring 65 is compressed. Under the action of the spring force, the suction cup 66 is pressed tightly against the surface of the aluminum disk, thereby improving the sealing between the suction cup 66 and the aluminum disk, thereby ensuring the stable adsorption of the aluminum disk by the suction cup 66. When the suction cup assembly 6 lifts the aluminum disk, the elastic force on the spring is released, and the air guide tube 64 is lowered and reset. The above design can improve the sealing between the suction cup 66 and the aluminum disk when the suction cup assembly 6 is adsorbed, thereby ensuring the stable adsorption of the aluminum disk by the suction cup 66.

[0046] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
