Description

Technical Field

[0001] This utility model relates to the field of measuring device technology, and more specifically, to a device for measuring the shape deviation of a dish-shaped end cap. Background Technology

[0002] A dished head, also known as a spherical head with a folded edge, is a product consisting of a spherical surface, a cylindrical straight edge of a certain height, and a transition section with a radius of curvature smaller than the radius of the spherical surface connecting the two parts.

[0003] When operators complete the production of dished heads, as they are container sealing components, the tolerance requirements for them are very high. At this time, it is necessary to measure their shape deviation. In the existing technology, the measurement method for dished heads is often that the operator first makes a rough measurement of the shape of the dished head by visual inspection based on experience, and then repeatedly measures the diameter of the dished head with a ruler. Although this method can measure the shape of the dished head, the deviation is large, so the measurement effect is not good, resulting in a low product yield and even affecting subsequent normal use. Therefore, it needs to be improved. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a device for measuring the shape deviation of a dished head, which has the advantage of accurately measuring the shape of the dished head.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for measuring the shape deviation of a dished head, comprising:

[0006] The base has a circular ring movably fitted inside its top end, and a toothed ring is fixedly installed at the top end of the circular ring.

[0007] A measuring mechanism, wherein the measuring mechanism is disposed on the outer surface of the toothed ring;

[0008] The measuring mechanism includes a connecting block. The bottom of the connecting block is fixedly connected to the outer surface of the toothed ring. A displacement sensor is fixedly installed at the top of the connecting block. A square rod is movably sleeved inside the displacement sensor. A fixing plate is fixedly sleeved on the outer surface of the square rod. A spring is fixedly installed on the outer surface of the fixing plate. The other end of the spring is fixedly connected to the outer surface of the displacement sensor. A fixing block is fixedly installed on the right side of the fixing plate. A screw is movably sleeved inside the fixing block. A turning block is fixedly installed at the right end of the screw. A movable block is threaded onto the outer surface of the screw. The outer surface of the movable block is movably sleeved with the inside of the fixing block. A roller is movably sleeved on the outer surface of the bottom of the movable block.

[0009] As a preferred embodiment of this utility model, a drive motor is fixedly installed at the front of the bottom end of the base, and a rotating shaft is fixedly sleeved at the other end of the output shaft of the drive motor.

[0010] As a preferred embodiment of this utility model, a gear is fixedly sleeved on the outer surface of the rotating shaft, and the outer surface of the gear meshes with the outer surface of the gear ring.

[0011] As a preferred embodiment of this utility model, a fixing frame is fixedly installed at the top of the base, and a limiting block is fixedly installed inside the fixing frame.

[0012] As a preferred embodiment of this utility model, the limiting block is internally connected to a movable rod, the other end of the movable rod is fixedly installed with a lifting block, and the bottom end of the lifting block is fixedly installed with a clamping block.

[0013] As a preferred technical solution of this utility model, a moving rod is movably sleeved on the outer surface of the lifting block, and a rotating block is movably sleeved on the outer surface of the moving rod. There are two rotating blocks, and a support shaft and a rotating shaft are respectively fixedly sleeved inside the two rotating blocks. The opposite ends of the support shaft and the rotating shaft are movably sleeved inside the fixed frame.

[0014] As a preferred embodiment of this utility model, a bracket is fixedly installed on the outer surface of the fixed frame, a power motor is fixedly installed on the right side of the bracket, a short shaft is fixedly sleeved on the other end of the output shaft of the power motor, and the left end of the short shaft is fixedly sleeved with the inside of the rotating shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model incorporates a displacement sensor, a square rod, a screw, and rollers. Since the screw is threadedly connected to the movable block, its rotation drives the rollers to move in the opposite direction via the movable block. The rollers then contact the dished head during this movement. When the toothed ring drives the connecting block to rotate as a whole, the rollers measure the shape of the dished head during rotation. If the rollers move during rotation, it indicates that the dished head shape is irregular. In this case, the rollers drive the fixed block to move via the movable block and the screw. The fixed block then drives the square rod to move along the inside of the displacement sensor via the fixed plate. The displacement sensor will then issue an alarm, enabling accurate measurement of the dished head shape. The design of the two springs provides a good reset effect for the overall movement of the square rod.

[0017] 2. This utility model incorporates a rotating block, a moving rod, a limiting block, and a power motor. When the power motor is running, the short shaft drives the rotating block to rotate via the rotating shaft. The rotating block then drives the moving rod to move. Due to the design of the support shaft, the rotating block receives good support. Simultaneously, the moving rod drives the clamping block to move. Because the limiting block limits the moving rod, the clamping block drives the two moving rods to move downwards. At the same time, the clamping block moves downwards under the influence of the lifting block. When the bottom end of the clamping block contacts the dished head, it clamps the dished head, thus quickly fixing the dished head. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 6As shown, this utility model provides a device for measuring the shape deviation of a dished head, comprising:

[0027] The base 1 has a ring 2 that is movably fitted inside the top of the base 1, and a toothed ring 3 that is fixedly installed on the top of the ring 2.

[0028] The measuring mechanism is set on the outer surface of the toothed ring 3;

[0029] The measuring mechanism includes a connecting block 4, the bottom of which is fixedly connected to the outer surface of the toothed ring 3. A displacement sensor 5 is fixedly installed at the top of the connecting block 4. A square rod 6 is movably sleeved inside the displacement sensor 5. A fixing plate 7 is fixedly sleeved on the outer surface of the square rod 6. A spring 8 is fixedly installed on the outer surface of the fixing plate 7. The other end of the spring 8 is fixedly connected to the outer surface of the displacement sensor 5. A fixing block 9 is fixedly installed on the right side of the fixing plate 7. A screw 10 is movably sleeved inside the fixing block 9. A turning block 11 is fixedly installed at the right end of the screw 10. A movable block 12 is threaded onto the outer surface of the screw 10. The outer surface of the movable block 12 is movably sleeved with the inside of the fixing block 9. A roller 13 is movably sleeved on the outer surface of the bottom of the movable block 12.

[0030] When the operator rotates the rotating block 11, it drives the screw 10 to rotate. Since the screw 10 is threadedly connected to the movable block 12, and due to the internal limit of the fixed block 9, the screw 10 drives the two movable blocks 12 to move in opposite directions. Then, the two rollers 13 move in opposite directions under the influence of the two movable blocks 12. Subsequently, the two rollers 13 will contact the dished head during this movement. Because the outer surface of the ring 2 is movably connected to the inside of the base 1, the toothed ring 3 can only drive the ring 2 along... The base 1 rotates inside the top. When the toothed ring 3 rotates, it will drive the connecting block 4 to rotate as a whole. At this time, the two rollers 13 will rotate along the outer surface of the dish head. When the two rollers 13 are displaced during rotation, it indicates that the shape of the dish head is irregular. At this time, the rollers 13 will drive the fixed block 9 to move through the movable block 12 and the screw 10. Then, the fixed block 9 will drive the square rod 6 to move along the inside of the displacement sensor 5 through the fixed plate 7. At this time, the displacement sensor 5 will detect the displacement of the square rod 6 and issue an alarm.

[0031] Among them, a drive motor 14 is fixedly installed at the front of the bottom end of the base 1, and a rotating shaft 15 is fixedly sleeved at the other end of the output shaft of the drive motor 14.

[0032] When the drive motor 14 is running, the rotating shaft 15 will rotate.

[0033] Among them, a gear 16 is fixedly sleeved on the outer surface of the rotating shaft 15, and the outer surface of the gear 16 meshes with the outer surface of the gear ring 3.

[0034] Since the outer surface of gear 16 meshes with the outer surface of gear ring 3, when the rotating shaft 15 drives gear 16 to rotate, gear ring 3 will rotate under the drive of gear 16.

[0035] The base 1 has a fixed bracket 17 fixedly installed at its top, and a limit block 18 is fixedly installed inside the fixed bracket 17.

[0036] Due to the design of the limiting block 18, the object located inside it will be limited, allowing its movement to be vertical.

[0037] The limiting block 18 is internally connected to a movable rod 19, and a lifting block 20 is fixedly installed at the other end of the movable rod 19. A clamping block 21 is fixedly installed at the bottom end of the lifting block 20.

[0038] Due to the limiting block 18, the lifting block 20 can only drive the two movable rods 19 to move up and down along the inside of the two limiting blocks 18. At the same time, the clamping block 21 will move up and down under the drive of the lifting block 20. When the bottom end of the clamping block 21 contacts the dished head during the downward movement, it will squeeze it, thereby fixing the dished head.

[0039] Among them, the outer surface of the lifting block 20 is movably sleeved with a moving rod 22, the outer surface of the moving rod 22 is movably sleeved with a rotating block 23, there are two rotating blocks 23, and the two rotating blocks 23 are respectively fixedly sleeved with a support shaft 24 and a rotating shaft 25, and the opposite ends of the support shaft 24 and the rotating shaft 25 are movably sleeved with the inside of the fixed frame 17.

[0040] When the rotating shaft 25 rotates, it will drive the rotating block 23 to rotate. At this time, the moving rod 22 will move under the drive of the rotating block 23. Due to the design of the support shaft 24, it will provide good support for the rotating block 23. At the same time, the bottom end of the moving rod 22 will squeeze the clamping block 21, causing the clamping block 21 to move downward.

[0041] The bracket 26 is fixedly installed on the outer surface of the fixed frame 17. The power motor 27 is fixedly installed on the right side of the bracket 26. The other end of the output shaft of the power motor 27 is fixedly sleeved with a short shaft 28. The left end of the short shaft 28 is fixedly sleeved with the inside of the rotating shaft 25.

[0042] When the power motor 27 is running, the short shaft 28 will drive the rotating shaft 25 to rotate.

[0043] Working principle and usage process of this utility model:

[0044] First, the operator places the dished head on the top of the base 1. Then, the operator starts the power motor 27. At this time, the short shaft 28 will drive the rotating shaft 25 to rotate. The rotating shaft 25 will drive the rotating block 23 to rotate. Due to the design of the support shaft 24, the rotating block 23 will be well supported. At the same time, the two rotating blocks 23 will drive the moving rod 22 to move during rotation. At this time, the bottom end of the moving rod 22 will push the lifting block 20, so that the lifting block 20 will drive the clamping block 21 and the two movable rods 19 to move. Due to the design of the two limit blocks 18, the movement of the two movable rods 19 will be limited, so that the two movable rods 19 can only move up and down. At this time, the lifting block 20 will drive the two movable rods 19 to move downward along the inside of the two limit blocks 18. At the same time, the clamping block 21 will move downward under the drive of the lifting block 20. When the bottom end of the clamping block 21 contacts the dished head, the clamping block 21 will clamp the dished head, thereby realizing the function of quickly fixing the dished head.

[0045] The operator then rotates the screw 11, causing the screw 10 to rotate. Since the outer surface of the screw 10 is threaded into the two movable blocks 12, its rotation causes the two movable blocks 12 to move towards each other along the interior of the fixed block 9. Simultaneously, the two rollers 13 move towards each other, driven by the movable blocks 12. The outer surfaces of the rollers 13 then contact the outer surface of the dish-shaped head during this movement. The operator then starts the drive motor 14, causing the shaft 15 to rotate the gear 16. Since the outer surface of the gear 16 meshes with the outer surface of the gear ring 3, the gear 16 rotates the gear ring 3. Next, the toothed ring 3 will drive the connecting block 4 to rotate as a whole. At this time, the two rollers 13 will rotate along the outer surface of the dish head. If the shape of the dish head is irregular, it will squeeze and push the two rollers 13. Then, the two rollers 13 will drive the fixed block 9 to move as a whole through the two movable blocks 12. Then, the fixed block 9 will drive the square rod 6 to move along the inside of the displacement sensor 5 through the fixed plate 7. When the displacement sensor 5 detects that the square rod 6 has moved, it will issue an alarm, thereby realizing the function of accurately measuring the shape of the dish head. During this process, the two springs 8 will be stretched and compressed respectively. Due to the design of the two springs 8, the movement of the square rod 6 as a whole will be well reset.
