Description
Technical Field
[0001] This utility model relates to the field of diamond grinding and polishing machine technology, and more specifically, to a clamping locking structure for a diamond grinding and polishing machine. Background Technology
[0002] In existing diamond polishing machines, the water drill chuck is usually set on a chuck mounting base before water drill polishing is performed. To prevent the chuck from shaking, at least two cylinders, electric cylinders, or motors are usually used in conjunction with hooks to lock the chuck on the chuck mounting base. However, locking with different cylinders or electric cylinders will result in errors in synchronization, which can easily damage the chuck.
[0003] Chinese Patent No. CN202320546155.X discloses a clamp locking mechanism for a diamond grinding and polishing machine, including a clamp mounting base. The clamp mounting base is provided with a guide groove for the clamp to slide into and a locking structure for locking the clamp onto the guide groove. The locking structure includes a pressing member, a hook, a rocker, and a driving member for driving the pressing member to press or reset. There are two rockers and two hooks, which correspond one to one. The rocker is oscillating on the clamp mounting base, with one end hinged to the pressing member and the other end hinged to the corresponding hook. When the clamp slides from the guide groove to the designated position, the driving member drives the pressing member to move. At this time, the rocker pries, thereby driving the hook to hook the clamp onto the inner wall of the guide groove, thus restricting the movement of the clamp. The two hooks can be pulled simultaneously by one driving member.
[0004] Traditional locking mechanisms tighten the clamp by lifting the hooks, but the flatness of the clamps is difficult to maintain consistently, resulting in errors. This can lead to the following situation: when one hook clamps the clamp, there may be a gap between the hook on the other side and the clamp. Existing hooks are operated synchronously by the locking mechanism, resulting in inconsistent tightness on both sides and preventing automatic adjustment. To address this issue, the clamp locking mechanism is optimized. Utility Model Content
[0005] This invention overcomes the shortcomings of the prior art and provides a clamping locking structure for a diamond grinding and polishing machine. Its structure is reasonably designed, and multiple clamping components can be driven to move synchronously by a single locking cylinder, reducing the errors that may be caused by multiple sets of cylinders, and making the clamping synchronization more accurate.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A clamping locking structure for a diamond grinding and polishing machine includes a clamping seat and a clamp mounted on the clamping seat. A locking cylinder is provided on the clamping seat, and the locking cylinder is connected to a shaft frame with a main shaft. At least one clamping assembly linked to the main shaft is provided on the clamping seat. The clamping assembly includes a guide seat on the clamping seat, a strip hole on the guide seat through which the main shaft passes, a linkage block connected to the strip hole on the guide seat via the main shaft, a hinge seat on the clamping seat, a locking hook that can clamp the clamp to the clamping seat, and a locking block that drives the locking hook to move. One end of the locking block is rotatably connected to the linkage block, and the other end of the locking block is rotatably connected to the locking hook. A hinge part is provided on the locking block between the two ends, and the hinge part is hinged to the hinge seat. A pressing part is provided on the locking block near the locking hook to engage with or disengage from the locking hook.
[0007] By adopting the above technical solution, clamping components can be set in two, three, or more to achieve stable clamping of the fixture. A single locking cylinder can drive multiple clamping components to operate synchronously, reducing potential errors from multiple cylinders and resulting in higher clamping synchronization and greater precision. Specifically, the locking hook is driven by the pressing part of the locking block. When the pressing part presses against the locking hook, the locking hook clamps the fixture; when the pressing part separates from the locking hook, the locking hook disengages from the fixture.
[0008] Preferably, the lock hook is connected to a buffer that causes the lock hook to rotate. The buffer is configured as a spring or an active cylinder and is mounted on the clamp seat or lock block.
[0009] By adopting the above technical solution, the buffer can be an active cylinder or a passive spring. Its main purpose is to provide a buffering force for the lock hook during rotation and to provide an active rotational force for the lock hook, so as to achieve the locking or separation of the lock hook.
[0010] Preferably, a pad is provided between the clamp and the clamp seat, and the pad or the clamp seat is provided with a relief groove that matches the hook of the lock hook.
[0011] By adopting the above technical solution, the setting of the clearance groove can provide a accommodating space for the hook.
[0012] Preferably, the pad or fixture base is provided with a positioning structure for positioning the fixture, and the positioning structure is configured as a limiting groove.
[0013] By adopting the above technical solution, specifically, the limiting groove can be a dovetail groove set on the pad to achieve initial positioning during fixture installation.
[0014] Preferably, a frame is provided on the fixture seat, a locking cylinder is installed on the frame, and the locking cylinder, main shaft and guide seat are located on the side of the fixture seat away from the fixture.
[0015] By adopting the above technical solution, and by setting up a frame, better installation support is provided for the locking cylinder. The locking cylinder, main shaft and guide seat are located on the side of the clamp seat away from the clamp, which can reduce the space occupied on the clamp side, facilitate the replacement of the clamp after the locking hook is unlocked, and facilitate the grinding and polishing of the water drill when the locking hook is locked.
[0016] Preferably, the fixture base is provided with a rotating assembly for driving the fixture pin to rotate. The rotating assembly includes a rotating motor, a shaft driven by the rotating motor, a docking part located at the end of the shaft and capable of docking with the fixture, and a translation unit located on the fixture base and capable of driving the docking part to translate relative to the shaft. The translation unit includes a translation cylinder, a connecting frame connected to the translation cylinder and the docking part, and a guide slide member located on the fixture base and connected to the connecting frame.
[0017] By adopting the above technical solution, when installing the fixture onto the fixture base, the mating part can be moved away from the fixture first. After the fixture is positioned, the mating part can be moved to mate with the fixture at the corresponding position. This ensures the accuracy of the mating and avoids damage to the components caused by collision interference.
[0018] Preferably, it also includes a frame, on which a flipping assembly for driving the fixture seat to flip is provided, the flipping assembly including a servo motor for driving the fixture seat and a reduction gearbox.
[0019] By adopting the above technical solution and setting up a servo motor and a reduction gearbox, the rotation angle of the fixture can be precisely controlled, thereby improving machining accuracy.
[0020] Preferably, the clamp seat is connected to a tilting shaft, the tilting shaft is connected to a brake disc, and a brake pump is installed on the brake disc.
[0021] By adopting the above technical solution, the brake disc and brake pump can be used to brake the tilting shaft, ensuring the positional accuracy of the fixture seat after tilting. Attached Figure Description

[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] like Figure 1-7 As shown, a clamping locking structure for a diamond grinding and polishing machine includes a clamping base 1 and a clamp 2 mounted on the clamping base 1. A locking cylinder 3 is provided on the clamping base 1, and the locking cylinder 3 is connected to a shaft bracket 31 having a main shaft 32. At least one clamping assembly 4 is provided on the clamping base 1 and is linked to the main shaft 32. The clamping assembly 4 includes a guide seat 41 on the clamping base 1, a slotted hole 42 on the guide seat 41 through which the main shaft 32 passes, and a coupling connected to the slotted hole 42 of the guide seat 41 via the main shaft 32. The moving block 43, the hinge seat 44 provided on the clamp seat 1, the locking hook 45 that can clamp the clamp 2 on the clamp seat 1, and the locking block 46 that drives the locking hook 45 to move. One end of the locking block 46 is rotatably connected to the linkage block 43, and the other end of the locking block 46 is rotatably connected to the locking hook 45. The locking block 46 is provided with a hinge part 461 between the two ends. The hinge part 461 is hinged to the hinge seat 44. The locking block 46 is provided with a pressing part 462 near the locking hook 45 that is engaged with or disengaged from the locking hook 45.
[0026] By adopting the above technical solution, clamping components 4 can be set in two, three, or more to achieve stable clamping of the fixture 2. Multiple clamping components 4 can be driven to operate synchronously by a single locking cylinder 3, reducing potential errors from multiple cylinders and resulting in higher clamping synchronization and greater precision. Specifically, the locking hook 45 is driven by the pressing part 462 of the locking block 46. When the pressing part 462 presses against the locking hook 45, the locking hook 45 clamps the fixture 2; when the pressing part 462 separates from the locking hook 45, the locking hook 45 disengages from the fixture 2.
[0027] The locking hook 45 is connected to a buffer member 5 that causes the locking hook 45 to rotate. The buffer member 5 is configured as a spring or an active cylinder and is mounted on the clamp seat 1 or the locking block 46. The buffer member 5 can be an active cylinder or a passive spring. Its main purpose is to provide a buffering force for the locking hook 45 during rotation and to provide an active rotational force for the locking hook 45, so as to achieve locking or unlocking of the locking hook 45.
[0028] A pad 6 is provided between the clamp 2 and the clamp base 1. The pad 6 or the clamp base 1 is provided with a relief groove 61 that is adapted to the hook part 451 of the locking hook 45. The relief groove 61 provides a space for the hook part 451.
[0029] Furthermore, a positioning structure for positioning the fixture 2 is provided on the pad 6 or the fixture base 1, and the positioning structure is configured as a limiting groove 62. Specifically, the limiting groove 62 can be a dovetail groove provided on the pad 6 to achieve initial positioning of the fixture 2 during installation.
[0030] A frame 11 is provided on the fixture base 1, and a locking cylinder 3 is installed on the frame 11. The locking cylinder 3, the main shaft 32, and the guide seat 41 are located on the side of the fixture base 1 away from the fixture 2. By providing the frame 11, better installation support is provided for the locking cylinder. The location of the locking cylinder 3, the main shaft 32, and the guide seat 41 on the side of the fixture base 1 away from the fixture 2 reduces the space occupied on the side of the fixture 2, making it easier to replace the fixture 2 after the locking hook 45 is unlocked, and to polish the water drill when the locking hook 45 is locked.
[0031] Furthermore, the fixture base 1 is equipped with a rotating assembly 7 that drives the clamping pin 21 of the fixture 2 to rotate. The rotating assembly 7 includes a rotating motor 71, a shaft 72 driven by the rotating motor 71, a docking part 73 located at the end of the shaft 72 and capable of docking with the fixture 2, and a translation unit 74 located on the fixture base 1 and capable of driving the docking part 73 to translate relative to the shaft 72. The translation unit 74 includes a translation cylinder 75, a connecting frame 76 connected to the translation cylinder 75 and the docking part 73, and a guide slide 77 located on the fixture base 1 and connected to the connecting frame 76. When installing the fixture 2 onto the fixture base 1, the docking part 73 can be moved away from the fixture 2 first. After the fixture 2 is positioned, the docking part 73 can be moved again so that the docking part 73 docks with the corresponding position on the fixture 2. This ensures the accuracy of docking and avoids damage to the components caused by collision interference. The docking part 73 and the shaft 72 are connected by a keyway structure.
[0032] Additionally, the machine includes a frame 8, on which a tilting assembly 81 is mounted to drive the fixture seat 1 to tilt. The tilting assembly 81 includes a servo motor 82 and a reduction gearbox 83 that drive the fixture seat 1. By setting the servo motor 82 and the reduction gearbox 83, the tilting angle of the fixture seat 1 can be precisely controlled, thereby improving machining accuracy.
[0033] The fixture base 1 is connected to a tilting shaft 9, which in turn is connected to a brake disc 91. A brake pump 92 is mounted on the brake disc 91. The brake disc 91 and the brake pump 92 are used to brake the tilting shaft 9, ensuring the positional accuracy of the fixture base 1 after tilting.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
