Abstract
Description
Technical Field
[0001] This utility model relates to the field of inkstone processing fixture technology, specifically a clamping mechanism for inkstone polishing machines. Background Technology
[0002] An inkstone, also known as a "inkstone," is one of the Four Treasures of the Study in traditional Chinese culture. It is a tool for grinding ink sticks and has both practical and artistic value.
[0003] Inkstones are generally round, and during processing, clamping equipment is needed to fix them in place. Then, external grinding equipment is used to polish the inkstone circumferentially. In the inkstone processing process, traditional methods are difficult to automatically drive the inkstone to rotate after clamping and fixing it in order to cooperate with the external grinding equipment to fully process the exterior of the inkstone, resulting in a slow processing speed. At the same time, the inkstone lacks an effective locking mechanism when rotating during processing, which affects the processing stability and makes it inconvenient for workers to perform different processing operations. In addition, the components used to lock the position of the rotating shaft are not stable enough, and there may be a return to their original position when fixing the rotating shaft, which in turn affects the overall processing speed.

[0024] 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.
[0025] This utility model provides a technical solution, please refer to [link / reference]. Figure 1 and Figure 2 The inkstone polishing machine uses a clamping mechanism, which includes: a worktable 1, a base 3, and a rotating shaft 4. The base 3 and the rotating shaft 4 are respectively mounted on the left and right sides of the upper end of the worktable 1. The top of the worktable 1 is provided with a sliding groove 2, and the bottom of the inner cavity of the sliding groove 2 is evenly provided with slots 21. A hollow ring 5 is slidably connected to the outside of the rotating shaft 4. Limiting blocks 51 are evenly distributed in the inner cavity of the hollow ring 5. A long shaft 52 is connected to the bottom of the hollow ring 5. A sliding block 53 is connected to the bottom of the long shaft 52. The sliding block 53 is slidably connected to the sliding groove 2. A locking mechanism 6 is mounted on the outside of the long shaft 52.
[0026] The worktable 1 can support the base 3 and the rotating shaft 4. The slide 2 can guide the hollow ring 5. The slot 21 can work with the locking mechanism 6 to lock the position of the hollow ring 5. The hollow ring 5 can slide outside the three-jaw chuck assembly 41. The limit block 51 can be inserted into the inner cavity of the limit groove 42 to lock the rotation of the three-jaw chuck assembly 41. The three-jaw chuck assembly 41 is a common three-jaw chuck device in the prior art, used to clamp the inkstone. The jaws of the three-jaw chuck assembly 41 are equipped with rubber sleeves to prevent the three-jaw chuck assembly 41 from damaging the inkstone.
[0027] Please see Figure 3 and Figure 4 The locking mechanism 6 includes a hollow cylinder 61 and a slotted ring 63. The bottom sides of the hollow cylinder 61 are evenly equipped with abutment arms 62, and the bottom sides of the slotted ring 63 are connected with protruding rods 65, which are inserted into the top of the sliding block 53.
[0028] The hollow cylinder 61 can rotate outside the long shaft 52. The hollow cylinder 61 is connected to the long shaft 52 through a bearing. The abutting arm 62 can abut against the slotted ring 63 to descend. The slotted ring 63 can drive the protruding rod 65 to insert into the inside of the slot 21 to lock the position of the sliding block 53. The inside of the slot 21 and the outside of the protruding rod 65 are both designed with rounded corners.
[0029] A three-jaw chuck assembly 41 is mounted on the right side of the rotating shaft 4. Limiting grooves 42 are evenly opened on the outside of the three-jaw chuck assembly 41. A limiting seat 43 is sleeved on the outside of the rotating shaft 4 through a bearing. The limiting seat 43 is connected to the worktable 1.
[0030] A geared motor assembly 45 is mounted on the outside of the rotating shaft 4 via a belt 44. The geared motor assembly 45 is mounted on the outside of the worktable 1 via a motor base 46. The belt 44 can transmit the power of the geared motor assembly 45 to the rotating shaft 4, thereby causing the rotating shaft 4 to rotate. The motor base 46 can fix the geared motor assembly 45. The geared motor assembly 45 is a common adjustable speed geared motor device in the prior art.
[0031] A protective shell 11 is installed on the left side of the workbench 1. The protective shell 11 is fitted over the belt 44. The protective shell 11 can protect the belt 44 and improve the transmission effect of the belt 44. Lifting springs 64 are connected to both sides of the bottom of the slotted ring 63. The lifting springs 64 are connected to the sliding block 53. The lifting springs 64 can make the slotted ring 63 return to its original position after the movement is completed.
[0032] Support seats 33 are connected to both sides of the top of the base 3. A T-shaped rod 31 is inserted into the inner cavity of the support seat 33. A return spring 32 is connected between the T-shaped rod 31 and the support seat 33. A chuck 34 is connected to the left side of the T-shaped rod 31 through a bearing seat. The support seat 33 can support the T-shaped rod 31. The chuck 34 can rotate outside the T-shaped rod 31. The return spring 32 facilitates the T-shaped rod 31 to return to its original position after being pulled. The base 3 can support the support seat 33.
[0033] In this design, the initial state of the reset spring 32 is the contracted state. After being stretched, it will retract on its own to achieve the reset effect. The initial state of the lifting spring 64 is the stretched state. After being compressed, it will push upward to support the slotted ring 63.
[0034] V-shaped grooves are provided on both sides of the top of the slotted ring 63. The contact arm 62 is slidably disposed inside the V-shaped groove. The V-shaped groove facilitates the contact arm 62 to drive the slotted ring 63 to descend when it rotates.
[0035] This solution moves the T-shaped rod 31, causing it to disengage from the hollow ring 5. The round inkstone is then placed inside the three-jaw chuck assembly 41, which clamps the inkstone in place. The T-shaped rod 31 is then returned to its original position, clamping both sides of the inkstone. The reduction motor assembly 45 is then activated, driving the rotating shaft 4 to rotate via the belt 44. This, in turn, causes the inkstone to rotate, achieving a comprehensive polishing operation on the outer circumference of the inkstone. Compared to the traditional manual method, this practical mechanical clamping polishing solution significantly avoids the problem of out-of-roundness.
[0036] When the inkstone is being processed, a polishing mechanism is installed in the middle of the upper surface of the workbench 1. The mechanism consists of a motor and a polishing belt and is positioned between the hollow ring 5 and the chuck 34 of the clamping mechanism. The position of the polishing mechanism is adjustable, thereby achieving the function of polishing the outer circumference of the clamped circular inkstone. When the inkstone does not need to be rotated for polishing, the long shaft 52 is pushed so that the limiting block 51 is inserted into the limiting groove 42, thereby fixing the position of the three-jaw chuck assembly 41 and locking the position of the rotating shaft 4. At the same time, the hollow cylinder 61 is rotated 90 degrees so that the contact arm 62 presses the slotted ring 63 down, and the protruding rod 65 is inserted into the inner cavity of the slot 21, thereby fixing the position of the sliding block 53 and improving the stability of the hollow ring 5 in limiting the rotating shaft 4.
[0037] In operation, the workbench 1 is equipped with a dust collection fan on its side. The air inlet of the dust collection fan is aligned with the polishing mechanism, and the air outlet of the dust collection fan is connected to a dust collection bag, which can collect the dust generated during operation.
[0038] With the addition of a rotating shaft 4, a three-jaw chuck assembly 41, and a limiting seat 43, the inkstone is automatically driven to rotate after being clamped and fixed. This, combined with external grinding equipment, allows for complete processing of the inkstone's exterior, thereby increasing the processing speed. Simultaneously, the addition of a hollow ring 5, a limiting block 51, a long shaft 52, a sliding block 53, and a limiting groove 42 automatically locks the inkstone's rotation during processing, improving stability and facilitating different processing modes. Furthermore, the addition of a hollow cylinder 61, abutting arm 62, a slotted ring 63, a protruding rod 65, and a slot 21 automatically fixes the position of the sliding block 53 when the hollow ring 5 locks the position of the rotating shaft 4, improving the stability of the hollow ring 5 and preventing it from returning to its original position when fixing the rotating shaft 4, which would affect the processing speed.
