Description

Technical Field

[0001] The present application relates to the technical field of disassembly equipment, and in particular to a seal disassembly device for a water meter copper seal counter. Background Art

[0002] The copper-sealed counter for water meters is a crucial component of water meters, used to measure and record water usage. During production, the counter is typically placed inside a copper shell with a glass cover. A sealant is placed between the copper shell and the glass cover, and the outer edge of the copper shell is squeezed to create a secure seal.

[0003] When the copper-sealed water meter counters produced are unqualified, they need to be disassembled. Since the unqualified products produced are in the minority after all, the disassembly method of the copper-sealed water meter counters is relatively traditional.

[0004] When disassembling, first manually hold the product down, then use a knife to scrape off the sealing ring between the glass cover and the copper shell, and then pry open the glass cover. However, the surface of the copper seal counter of the water meter is relatively smooth and difficult to fix, making disassembly more troublesome. Summary of the Invention

[0005] In order to facilitate disassembly, the present application provides a water meter copper seal counter seal disassembly device.

[0006] This application provides a water meter copper seal counter seal removal device, which adopts the following technical solutions:

[0007] A water meter copper seal counter seal disassembly device, comprising

[0008] Loading platform;

[0009] A three-jaw chuck is rotatably mounted on the support platform, wherein a clamping space is formed on a side of the three-jaw chuck away from the support platform;

[0010] A driving member is provided on the bearing platform, and the driving member drives the three-jaw chuck to rotate;

[0011] A connecting column is provided on the supporting platform;

[0012] A support rod is hinged to the side of the connecting column away from the supporting platform, and the support rod can be flipped to be directly above the three-jaw chuck;

[0013] The knife body is arranged on the support rod. When the support rod is turned over to be just above the three-jaw chuck, the knife body is inserted into the area to be scraped.

[0014] By adopting the above technical solution, when scraping the sealing ring of the copper-sealed water meter counter, first flip the support rod toward the three-jaw chuck until the blade is inserted into the sealing ring in the gap between the glass cover and the copper shell. Then start the drive part to drive the three-jaw chuck to rotate, so that the blade scrapes the sealing ring. When the sealing ring is scraped, flip the support column away from the three-jaw chuck so that the blade is out of the gap between the glass cover and the copper shell. Finally, the glass cover can be pried out with tools such as a screwdriver and a sharp knife to complete the disassembly, greatly reducing the difficulty of disassembly. The whole process is simple, and the copper-sealed water meter counter is easy to fix and disassemble during disassembly, while reducing the risk of injury due to slipping during disassembly.

[0015] Optionally, a fixing nut is fixed on the supporting platform, and the connecting column is threadedly connected to the fixing nut.

[0016] By adopting the above technical solution, the connecting column is threadedly connected to the fixing nut, so that the connecting column can rotate in the circumferential direction, which is conducive to adjusting the position of the cutter head by rotating the connecting column, so that the cutter head can scrape the sealing ring of water meter copper seal counters with different diameters; at the same time, during the sealing ring scraping process, the fixing nut can limit the sliding of the connecting column in the vertical and horizontal directions, thereby improving the stability of the connecting column and facilitating use.

[0017] Optionally, a friction layer is provided on the surface of the support rod, and the friction layer is located away from the connecting column.

[0018] By adopting the above technical solution, when the blade scrapes the sealing ring, the support rod is gripped by the friction layer, thereby increasing the friction between the blade and the support rod when gripping, and reducing the possibility of slipping when scraping the sealing ring.

[0019] Optionally, the blade body includes a blade and a chuck;

[0020] The chuck is arranged on the supporting rod, the blade is detachably connected to the chuck, and the blade is inclined away from the chuck to form a guide surface.

[0021] By adopting the above technical solution, the blade can be detached from the chuck, and the position of the blade tip can be adjusted to facilitate the insertion of the blade tip into the gap between the glass cover and the copper shell. At the same time, the guide surface can guide the scraped sealing ring to escape from the gap between the glass cover and the copper shell.

[0022] Optionally, the clamp is detachably fixed to the support rod.

[0023] By adopting the above technical solution, the chuck can be detachably fixed to the support rod, making it convenient to disassemble and maintain the chuck.

[0024] Optionally, the connecting column is formed with a hinge groove, the connecting column is slidably provided with a hinge shaft passing through the hinge groove, and the connecting column is provided with a limiting member for limiting the rotation of the hinge shaft;

[0025] The support rod is formed with a connection hole for the hinge shaft to pass through;

[0026] The connecting hole is provided with a mounting groove on its peripheral wall, and supporting teeth are evenly spaced along the circumferential direction on the peripheral wall of the mounting groove. The hinge shaft is provided with sliding teeth on its outer peripheral side.

[0027] The sliding teeth slide axially along the hinge shaft in the mounting groove, and the sliding teeth are engaged with the supporting teeth;

[0028] When the support rod flips toward the three-jaw chuck, the sliding teeth slide on the supporting teeth;

[0029] When the support rod flips in a direction away from the three-jaw chuck, the support teeth unidirectionally support the sliding teeth;

[0030] When the sliding teeth slide to be misaligned with the supporting teeth, the supporting rod can rotate freely.

[0031] By adopting the above technical solution, when the support rod flips in the direction away from the three-jaw chuck, the support teeth unidirectionally support the sliding teeth, limiting the rotation of the support rod and reducing the amount of force applied to the support rod toward the three-jaw chuck during the scraping process of the sealing ring.

[0032] Optionally, the limiting member is a limiting block, which is arranged on the connecting column, and a limiting groove extending in the axial direction and for the limiting block to slide is formed on the outer peripheral side of the hinge shaft.

[0033] By adopting the above technical solution, the limiting block is slidably connected in the limiting groove to limit the rotation of the hinge shaft.

[0034] Optionally, a push spring is provided in the connecting column, and the push spring pushes the hinge shaft to protrude out of the connecting column, at which time the sliding teeth are engaged with the supporting teeth.

[0035] By adopting the above technical solution, the push spring pushes the hinge shaft to protrude outside the connecting column, which is conducive to maintaining the state in which the sliding teeth and the supporting teeth are engaged.

[0036] Optionally, the connecting post is slidably provided with an abutment post protruding out of the connecting post, and the abutment post is aligned with the inner wall of the fixing nut;

[0037] The connecting post is provided with a driving post which slides up and down, and the driving post protrudes upward into the hinge slot;

[0038] The abutment column is inclined to form a driving surface aligned with the driving column, and when the driving column slides on the driving surface, it pushes the abutment column to press against the inner wall of the fixing nut;

[0039] A friction layer is formed on the end of the abutting column.

[0040] By adopting the above technical solution, when the support rod flips toward the three-jaw chuck, the support rod pushes the driving column to slide into the driving column, and pushes the abutting column to slide to the inner wall of the abutting fixing nut, which is beneficial to improving the stability of the connecting column.

[0041] Optionally, the driving column includes a column, and the column is provided in plurality and evenly arranged up and down;

[0042] The upper and lower adjacent cylinders are connected by threads.

[0043] By adopting the above technical solution, there are multiple columns and the upper and lower columns are connected by threads, so that the length of the driving column can be adjusted according to the height of the water meter copper seal counter.

[0044] In summary, this application has at least one of the following beneficial effects:

[0045] 1. The copper seal counter of the water meter is fixed by a three-jaw chuck. At the same time, the support rod is flipped to allow the blade to be inserted into the sealing ring. The three-jaw chuck is then rotated by the driving member, allowing the blade to scrape the sealing ring, greatly reducing the difficulty of disassembly. The copper seal counter of the water meter is easy to fix during disassembly, reducing the risk of injury during disassembly.

[0046] 2. When the support rod flips away from the three-jaw chuck, the support teeth support the sliding teeth in one direction, limiting the rotation of the support rod. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0055] The following is combined with Figure 1-7 This application is described in further detail.

[0056] The embodiment of the present application discloses a seal disassembly device for a water meter copper seal counter.

[0057] Example 1

[0058] See also Figure 1 and Figure 2 The disassembly device includes a supporting platform 1 and a three-jaw chuck 2, and the three-jaw chuck 2 is rotatably connected to the bottom of the supporting platform 1. The three-jaw chuck 2 includes claws, and the three-jaw chuck 2 forms a clamping space 21 for clamping the water meter copper seal counter. There are three claws and they are evenly spaced along the circumference, and the claws surround the clamping space 21. When the water meter copper seal counter is clamped into the clamping space 21, it is fixed by controlling the three claws to press against the outer peripheral side of the water meter copper seal counter. Since the principle of the three-jaw chuck 2 clamping the water meter copper seal counter is existing technology, it will not be elaborated here.

[0059] The disassembly device further includes a drive member 11, which is a drive motor. The drive motor is embedded and fixed in the carrier 1 and is located directly below the three-jaw chuck 2. The output shaft of the drive motor is fixedly connected to the three-jaw chuck 2. When the drive motor is started, it drives the three-jaw chuck 2 to rotate.

[0060] A fixing nut 12 is fixedly attached to the top of the support platform 1, located near the three-jaw chuck 2. The disassembly device also includes a connecting post 3 and a support rod 4. The connecting post 3 is threaded on its outer circumference and is threadedly connected to the fixing nut 12, allowing it to rotate circumferentially. The support rod 4 is hinged near its end to the side of the connecting post 3 facing away from the support platform 1, allowing it to be tilted toward or away from the three-jaw chuck.

[0061] See also Figure 2 and Figure 3 The disassembly device further includes a blade body 5, which includes a blade 51 and a chuck 52. The chuck 52 is secured to the center of the support rod 4 via a hexagon socket head bolt. The blade 51 is mounted on the chuck 52, which is clamped to secure the blade 51. The principle of clamping the blade 51 with the chuck 52 is well known in the art and will not be further elaborated upon here.

[0062] The blade 51 is cylindrical in structure, with a guide surface 511 formed at one end and a chuck 52 at the other end. The tip of the blade 51 is formed at one end of the guide surface 511. A friction layer 41 is fixedly connected to the outer circumference of the support rod 4. The friction layer 41 is located away from the connecting column 3. When the support rod 4 is turned, the friction layer 41 is grasped to reduce the possibility of slipping when grasping the support rod 4.

[0063] The implementation principle of the seal removal device for the water meter copper seal counter in the first embodiment of the present application is as follows:

[0064] When scraping the sealing ring of the copper-sealed counter of the water meter, first flip the support rod 4 to the top of the three-jaw chuck 2, and the blade 5 is now facing the clamping space 21. Then rotate the connecting column 3 to adjust the position of the blade 51 so that the tip of the blade 51 is aligned with the sealing ring of the copper-sealed counter of the water meter. Then press down the support rod 4 so that the tip of the blade 51 is inserted into the sealing ring. After that, start the drive motor to rotate the three-jaw chuck 2. During the rotation process, the guide surface 511 of the blade 51 is facing the sealing ring, and the scraped sealing ring debris is guided out of the gap between the glass cover and the copper shell. When the sealing ring is scraped off, flip the support column away from the three-jaw chuck 2 so that the blade 51 is out of the gap between the glass cover and the copper shell. Finally, the glass cover can be pried out with tools such as a screwdriver and a sharp knife to complete the disassembly.

[0065] Example 2

[0066] The difference between the second embodiment of the present application and the first embodiment is that:

[0067] See also Figure 4 and Figure 5 A hinge slot 31 is formed at one end of the connecting column 3 away from the supporting platform 1. A rotation slot is formed on the connecting column 3. The rotation slot is connected to the hinge slot 31, and the slot opening is located on the outer peripheral side wall of the connecting column 3. The connecting column 3 is provided with a hinge shaft 32, which is slidably connected to the rotation slot and passes through the hinge slot 31. The support rod 4 is formed with a connecting hole 42, and the hinge shaft 32 passes through the connecting hole 42, so that the support rod 4 is rotatably connected to the hinge shaft 32.

[0068] The connecting shaft is provided with a limiting member, a limiting block 33, which is fixed to the peripheral wall of the rotation groove. A limiting groove 322 is formed on the outer periphery of the hinge shaft 32, and the limiting groove 322 extends axially along the hinge shaft 32. The limiting block 33 is slidably connected to the limiting groove 322 to limit the rotation of the hinge shaft 32.

[0069] See also Figure 5 and Figure 6 The connecting hole 42 has a mounting groove 421 formed on its peripheral wall, extending circumferentially with the central axis of the connecting hole 42 as its center. A plurality of supporting teeth 422 are fixedly connected to the wall of the mounting groove 421 away from the connecting hole 42. The supporting teeth 422 are evenly spaced along the circumference. The hinge shaft 32 has a plurality of sliding teeth 321 fixedly connected to its outer peripheral side. The sliding teeth 321 are evenly spaced along the circumference and are located within the mounting groove 421. The mounting groove 421 has a width greater than that of the sliding teeth 321, and drives the hinge shaft 32 to slide, so that the sliding teeth 321 and the supporting teeth 422 are aligned with each other and mesh with each other. Simultaneously, the sliding of the hinge shaft 32 can drive the sliding teeth 321 away from the supporting teeth 422 until the sliding teeth 321 and the supporting teeth 422 are misaligned. At this point, the support rod 4 is in a freely rotating state.

[0070] The connecting column 3 is provided with a push spring 34, which is installed in the rotation groove. One end of the push spring 34 abuts the end of the hinge shaft 32, and the other end abuts the wall of the rotation groove. When the hinge shaft 32 is pressed into the rotation groove, the hinge shaft 32 drives the sliding teeth 321 away from the support teeth 422, and at the same time, the push spring 34 enters a compressed state. When the hinge shaft 32 is released, the push spring 34 elastically releases, pushing the hinge shaft 32 out of the rotation groove, driving the sliding teeth 321 to slide until the sliding teeth 321 abut the wall of the installation groove 421 away from the push spring 34. At this time, the hinge shaft 32 is pushed out of the connecting column 3, and the sliding teeth 321 mesh with the support teeth 422.

[0071] See also Figure 4 and Figure 6 When the sliding teeth 321 engage with the supporting teeth 422, the support rod 4 tilts toward the three-jaw chuck 2, causing the sliding teeth 321 to slide against the supporting teeth 422. When the support rod 4 tilts away from the three-jaw chuck 2, the supporting teeth 422 support the sliding teeth 321, limiting the tilting of the support rod 4 away from the three-jaw chuck 2 and reducing the force applied to the support rod 4 by the blade 51 during the process of scraping the sealing ring. During production, the support rod 4 is constructed in two halves. After the hinge shaft 32 is installed, the two halves of the support rod 4 are fixed by welding. The limiting block 33 is made of a material with elastic deformation capabilities and is squeezed into the limiting groove 322 during installation.

[0072] The implementation principle of the seal removal device for the water meter copper seal counter in the second embodiment of the present application is as follows:

[0073] When scraping the sealing ring of the copper seal counter of the water meter, the hinge shaft 32 protrudes out of the rotation groove, and the sliding teeth 321 mesh with the supporting teeth 422. At this time, when the support rod 4 is tilted toward the three-jaw chuck 2, the sliding teeth 321 slide on the supporting teeth 422. When the blade 51 scrapes the sealing ring, the sealing ring exerts a force on the blade 51, pushing the support rod 4 to tilt away from the three-jaw chuck 2. At this time, the supporting teeth 422 unidirectionally support the sliding teeth 321, limiting the tilting of the support rod 4 and reducing the amount of force applied to the support rod 4 toward the three-jaw chuck 2 during the scraping process.

[0074] Example 3

[0075] The difference between the third embodiment of the present application and the second embodiment is that:

[0076] See also Figure 7 The connecting column 3 is formed with an abutment groove that extends radially through the outside of the connecting column 3. There are multiple abutment grooves, evenly spaced circumferentially around the central axis of the connecting column 3. The abutment groove is located near the bottom of the connecting column 3, with the groove opening aligned with the inner circumferential sidewall of the fixing nut 12. A sliding groove extending axially is formed in the middle of the connecting column 3, connecting the abutment groove and the hinge groove 31. The connecting column 3 is provided with an abutment column 35, which corresponds to the abutment groove one-to-one and slides in the abutment groove.

[0077] The connecting column 3 is provided with a drive column 36, which includes multiple columns 352, evenly spaced vertically, with adjacent columns 352 threadedly connected. The drive column 36 slides up and down the chute and projects into the hinge slot 31. A drive surface 351 is formed on the side of the abutment column 35, which is inclined near the chute, facing the drive column 36. In the initial state, the bottom of the drive column 36 abuts the drive surface 351, and the top of the drive column 36 projects into the hinge slot 31. The length of the drive column 36 is determined by the height of the water meter's copper seal counter.

[0078] When the support rod 4 approaches the three-jaw chuck 2 (the three-jaw chuck 2 is Figure 4 When the direction (marked in the middle) is flipped until the tip of the blade 51 is inserted into the sealing ring, the support rod 4 pushes the driving column 36 to slide into the sliding groove. At this time, the driving column 36 slides on the driving surface 351, pushing the abutting column 35 to slide away from the sliding groove, so that the abutting column 35 presses against the inner peripheral side wall of the fixing nut 12, limiting the rotation of the connecting column 3, and improving the stability of the connecting column 3 during the scraping process of the sealing ring.

[0079] A rubber layer 353 is fixedly connected to the side of the abutting column 35 away from the slide groove. The rubber layer 353 is made of rubber material. When the friction between the abutting column 35 and the fixing nut 12 is increased, the stability of the connecting column 3 during the scraping process of the sealing ring is further improved.

[0080] The implementation principle of the seal removal device for the water meter copper seal counter in the third embodiment of the present application is as follows:

[0081] When scraping off the sealing ring of the copper seal counter of the water meter, flip the support rod 4 toward the three-jaw chuck 2 until the tip of the blade 51 is inserted into the sealing ring. At this time, the support rod 4 pushes the driving column 36 to slide downward, pushing the abutting column 35 to abut the inner peripheral side wall of the fixing nut 12, reducing the possibility of rotation of the connecting column 3 and improving the stability of the connecting column 3.

[0082] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
