Description
Technical Field
[0001] This utility model belongs to the field of tool grinding technology, and in particular relates to a grinding clamping structure adapted to different tool sizes. Background Technology
[0002] Currently, in the field of machining, cutting tools are the core cutting tools. Their cutting edge accuracy and surface quality directly determine the machining accuracy and surface roughness of the workpiece. In order to ensure the cutting performance of the cutting tools, the cutting edges of the cutting tools need to be ground by grinding equipment during the manufacturing process or after wear. The grinding clamp is a key positioning component in the tool grinding process. Its clamping stability, size adaptability and adjustment convenience have a decisive impact on grinding efficiency and machining quality.
[0003] The existing tool grinding clamping structures on the market have many technical defects that urgently need to be solved, making it difficult to meet the diverse tool grinding needs of modern machining. Among them, most existing clamping stands are fixed designs. After grinding, the tool still needs to be removed from the clamping stand and moved to a designated location or conveyor belt, which greatly increases the workload of the operators.
[0004] There is an urgent need for improvement, so we propose a grinding clamping structure that can be adapted to different tool sizes. Utility Model Content
[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a grinding clamping structure that is compatible with different tool sizes, thereby achieving the effect of quickly flipping and unloading the ground tools.
[0006] In view of this, the present invention provides a grinding clamping structure adapted to different tool sizes, comprising: A slide rail, on which a slider is slidably mounted, brackets are fixedly connected to the top two sides of the slider, and a drive assembly is mounted on the side wall of the slider; A limiting plate is fixedly installed on one side of the top of the slide rail. A first transverse groove is provided through the limiting plate. A rotating groove is connected to one side of the first transverse groove. A second transverse groove is connected to the other side of the rotating groove. The bracket is equipped with a flipping mechanism, and the flipping mechanism is connected to a moving shaft. The moving shaft is slidably connected to the first horizontal groove, the rotating groove, and the second horizontal groove, respectively. The flipping mechanism is equipped with a workbench, and a clamping assembly is provided on the workbench. When the moving shaft is between the beginning and end of the first transverse groove, the workbench remains horizontal. When the moving shaft is moved from the beginning to the end of the rotating groove, the workbench performs a flipping action simultaneously. When the moving shaft is between the beginning and end of the second transverse groove, the workbench remains vertical, so as to realize that the ground tool is automatically moved to the preset position and flipped for unloading.
[0007] Furthermore, the drive assembly includes a connecting frame fixedly mounted on the side wall of the slider, the middle of one side wall of the connecting frame being connected to the drive end of the first electric push rod, and the other end of the first electric push rod being fixedly mounted on the slide rail.
[0008] Furthermore, both the first and second transverse grooves are horizontally oriented, with the first transverse groove having a lower horizontal height than the second transverse groove. The rotating groove extends from one end of the first transverse groove to the end of the second transverse groove adjacent to the first transverse groove.
[0009] Furthermore, the flipping mechanism includes a rotating shaft rotatably mounted on the two supports, a right-angle bracket fixedly mounted on the rotating shaft, the right-angle bracket being distributed between the two supports, and a lever arm fixedly connected to one end of the rotating shaft through the side wall of the corresponding support, the lever arm being fixedly connected to one end of the moving shaft.
[0010] Furthermore, baffles are fixedly installed at the other end and the middle of the moving shaft. The outer diameter of the baffles is greater than the height of the first transverse groove, the rotating groove and the second transverse groove. The two baffles are distributed on both sides of the limiting plate.
[0011] Furthermore, the clamping assembly includes fixed seats that are fixedly connected to both sides of the top of the workbench. One fixed seat has a first clamping block on one side and the other fixed seat has a second clamping block on one side. The cross-sectional profiles of the first clamping block and the second clamping block are both wedge-shaped and symmetrically arranged about the center of the workbench.
[0012] Furthermore, a second electric push rod is fixedly installed on the side wall of one of the fixed seats. The driving end of the second electric push rod passes through the fixed seat and is fixedly connected to the second clamping block. A limit rod is fixedly connected to one end of the side wall of the second clamping block, and the limit rod is movably connected to the corresponding fixed seat.
[0013] Furthermore, both the workbench and the right-angle frame are provided with through mounting holes, and bolts are installed in the corresponding two mounting holes.
[0014] The beneficial effects of this utility model are: By using the first horizontal groove, the rotating groove, and the second horizontal groove on the limiting plate, combined with the sliding connection between the flipping mechanism and the moving shaft, the automatic switching between the horizontal grinding state and the vertical unloading state of the workbench is realized. When the moving shaft slides in the first horizontal groove, the workbench remains horizontal. When the moving shaft slides along the rotating groove, the workbench simultaneously completes the flipping action, eliminating the need for an additional independent flipping drive component and simplifying the overall structure. After the moving shaft enters the second horizontal groove, the workbench remains vertical, which can automatically move the ground tool to the preset unloading position, greatly reducing manual intervention and improving processing efficiency.

[0021] Reference Figures 1 to 4 Grinding clamping structures adapted to different tool sizes include: Slide rail 1, slider 11 is slidably mounted on slide rail 1, brackets 12 are fixedly connected to the top two sides of slider 11, and drive components are mounted on the side wall of slider 11. A limiting plate 24 is fixedly installed on one side of the top of the slide rail 1. A first transverse groove 25 is provided through the limiting plate 24. A rotating groove 26 is connected to one side of the first transverse groove 25, and a second transverse groove 27 is connected to the other side of the rotating groove 26. A flipping mechanism is installed on the bracket 12, and a moving shaft 23 is connected to the flipping mechanism. The moving shaft 23 is slidably connected to the first horizontal groove 25, the rotating groove 26 and the second horizontal groove 27 respectively. The flipping mechanism is equipped with a workbench 3, and a clamping assembly is provided on the workbench 3. When the moving shaft 23 is between the beginning and end of the first transverse groove 25, the workbench 3 remains horizontal. When the moving shaft 23 is moved from the beginning to the end of the rotating groove 26, the workbench 3 performs a flipping action simultaneously. When the moving shaft 23 is between the beginning and end of the second transverse groove 27, the workbench 3 remains vertical, so as to realize that the ground tool is automatically moved to the preset position and the flipping and unloading are completed.
[0022] As a preferred example of this utility model, firstly, the drive assembly starts and causes the slider 11 to slide linearly along the slide rail 1. The bracket 12 on the top of the slider 11 moves synchronously with the slider 11, thereby causing the flipping mechanism on the bracket 12 and the worktable 3 to move as a whole. During this process, the moving shaft 23 on the flipping mechanism is embedded in the groove structure of the limiting plate 24, slides along the groove trajectory, and provides guidance for the attitude switching of the worktable 3. When the equipment is in the grinding process, the moving shaft 23 is in the first transverse groove 25. Under the horizontal guidance of the first transverse groove 25, the flipping mechanism maintains a fixed attitude, and the worktable 3 maintains a horizontal state so as to clamp the tool fixed by the assembly. Grinding process; after grinding, the drive assembly continues to drive the slider 11 to move, driving the moving shaft 23 from the end of the first transverse groove 25 into the rotating groove 26. When the moving shaft 23 slides along the arc trajectory of the rotating groove 26, it will generate a rotational driving force on the flipping mechanism, causing the flipping mechanism to drive the worktable 3 to perform a flipping action synchronously. When the moving shaft 23 slides to the end of the rotating groove 26 and enters the second transverse groove 27, the flipping mechanism stops flipping due to the horizontal guidance of the second transverse groove 27, and the worktable 3 remains in a vertical state. At this time, the drive assembly drives the slider 11 to continue moving, moving the worktable 3 to the preset unloading position, completing the automatic flipping and unloading process of the tool.
[0023] In the example of this application, the drive assembly includes a connecting frame 13 fixedly mounted on the side wall of the slider 11. The middle of one side wall of the connecting frame 13 is connected to the drive end of the first electric push rod 14, and the other end of the first electric push rod 14 is fixedly mounted on the slide rail 1.
[0024] As a preferred example of this utility model, the first electric push rod 14 is fixedly installed on the slide rail 1, and its telescopic end is fixedly connected to the connecting frame 13 fixed on the side wall of the slider 11. When it is necessary to drive the workbench 3 to move, the first electric push rod 14 receives the control signal and performs the telescopic action. The telescopic force of the push rod is directly transmitted to the slider 11 through the connecting frame 13. Since the slider 11 and the slide rail 1 have a sliding fit structure, under the action of the push or pull force, the slider 11 will slide smoothly in a straight line along the extension direction of the slide rail 1.
[0025] In the example of this application, both the first horizontal groove 25 and the second horizontal groove 27 are arranged in the horizontal direction. The horizontal height of the first horizontal groove 25 is lower than that of the second horizontal groove 27. The rotating groove 26 extends from one end of the first horizontal groove 25 to the end of the second horizontal groove 27 adjacent to the first horizontal groove 25.
[0026] As a preferred example of this utility model, both the first transverse groove 25 and the second transverse groove 27 extend horizontally, and the horizontal height of the first transverse groove 25 is lower than that of the second transverse groove 27. The two are smoothly connected by an arc-shaped rotating groove 26, forming a complete horizontal, arc-shaped and horizontal guide trajectory. When the moving shaft 23 slides in the first transverse groove 25, because the first transverse groove 25 is horizontally set, the moving shaft 23 can only move horizontally and cannot produce vertical displacement, thus ensuring that the flipping mechanism and the worktable 3 maintain a horizontal posture. When the moving shaft 23 enters the rotating groove 26, the arc-shaped structure of the rotating groove 26 forces the moving shaft 23 to produce vertical displacement while moving horizontally. This displacement drives the flipping mechanism to rotate, realizing the flipping of the worktable 3. When the moving shaft 23 enters the second transverse groove 27, the horizontal structure of the second transverse groove 27 restricts the vertical displacement of the moving shaft 23, so that the moving shaft 23 only slides horizontally, the flipping mechanism remains fixed, and the worktable 3 maintains a vertical posture.
[0027] In the example of this application, the flipping mechanism includes a rotating shaft 2 that is rotatably mounted on two supports 12 via bearings. A right-angle bracket 21 is fixedly mounted on the rotating shaft 2 and distributed between the two supports 12. One end of the rotating shaft 2 passes through the side wall of the corresponding support 12 and is fixedly connected to a lever arm 22. The lever arm 22 is fixedly connected to one end of the moving shaft 23.
[0028] As a preferred example of this utility model, when the moving shaft 23 slides along the groove of the limiting plate 24, it will drive the lever arm 22 to move synchronously: when the moving shaft 23 slides horizontally in the first horizontal groove 25 or the second horizontal groove 27, the lever arm 22 only moves horizontally with the moving shaft 23, the rotating shaft 2 does not rotate, and the workbench 3 maintains the corresponding posture; when the moving shaft 23 slides along the rotating groove 26, it will drive the lever arm 22 to rotate around the axis of the rotating shaft 2, and the rotation driving force of the lever arm 22 is transmitted to the rotating shaft 2, so that the rotating shaft 2 drives the right-angle frame 21 to rotate synchronously. Since the workbench 3 is fixed to the right-angle frame 21, the rotation of the right-angle frame 21 will drive the workbench 3 to achieve the flipping action.
[0029] In the example of this application, baffles 28 are fixedly installed at the other end and the middle of the moving shaft 23. The outer diameter of the baffles 28 is greater than the height of the first transverse groove 25, the rotating groove 26 and the second transverse groove 27. The two baffles 28 are distributed on both sides of the limiting plate 24.
[0030] As a preferred example of this utility model, when the movable shaft 23 slides along the groove, the two baffles 28 are respectively attached to the two sides of the limiting plate 24 to form an axial limiting structure: if the movable shaft 23 tends to detach from the groove to one side along the axial direction, the baffle 28 on the same side will contact the side of the limiting plate 24, and the limiting plate 24 will generate a reaction force on the baffle 28 to prevent the movable shaft 23 from continuing to move axially; through the cooperative limiting of the two baffles 28, it is ensured that the movable shaft 23 always slides in the groove, avoiding the failure of the flipping mechanism or the offset of the workbench 3 due to the axial detachment of the movable shaft 23.
[0031] In the example of this application, the clamping assembly includes fixed seats 31 that are fixedly connected to both sides of the top of the workbench 3. One fixed seat 31 has a first clamping block 32 on one side and a second clamping block 33 on one side of the other fixed seat 31. The cross-sectional profiles of the first clamping block 32 and the second clamping block 33 are both wedge-shaped and are symmetrically arranged about the center of the workbench 3.
[0032] As a preferred example of this utility model, when clamping a cutting tool, the tool is placed between the two clamping blocks by adjusting the distance between the two clamping blocks. The inclined surface of the wedge-shaped clamping block is in contact with the surface of the cutting tool, which can clamp cutting tools of different sizes.
[0033] In the example of this application, a second electric push rod 34 is fixedly installed on the side wall of one of the fixed seats 31. The driving end of the second electric push rod 34 passes through the fixed seat 31 and is fixedly connected to the second clamping block 33. A limit rod 35 is fixedly connected to one end of the side wall of the second clamping block 33. The limit rod 35 is movably connected to the corresponding fixed seat 31.
[0034] As a preferred example of this utility model, when it is necessary to clamp the tool, the second electric push rod 34 receives a control signal and extends, pushing the second clamping block 33 to move towards the first clamping block 32 until the two clamping blocks clamp the tool. According to the size and specifications of the tool, the clamping force of the clamping blocks can be adjusted by controlling the extension and retraction of the second electric push rod 34. During the movement of the second clamping block 33, the limiting rod 35 slides along the guide hole of the fixed base 31, which restricts the movement direction of the second clamping block 33, preventing the second clamping block 33 from tilting or deviating during the movement, ensuring that the clamping surfaces of the first clamping block 32 and the second clamping block 33 always remain parallel, and ensuring the stability of the clamping. When it is necessary to release the tool, the second electric push rod 34 retracts, driving the second clamping block 33 to move away from the first clamping block 32, completing the tool release action.
[0035] In the example of this application, both the workbench 3 and the right-angle frame 21 are provided with through mounting holes 36, and bolts are installed in the corresponding two mounting holes 36.
[0036] As a preferred example of this utility model, mounting holes 36 are provided at corresponding positions on both the workbench 3 and the right-angle frame 21. When installing the workbench 3, the workbench 3 is placed on the right-angle frame 21, aligning the mounting holes 36. Then, bolts are passed through the aligned mounting holes 36, and nuts are tightened to achieve a fixed connection between the workbench 3 and the right-angle frame 21. The tightening force of the bolts ensures a firm connection between the two, preventing relative loosening during grinding or flipping. When the workbench 3 needs to be replaced, simply unscrew the bolts to remove the workbench 3 from the right-angle frame 21. After replacing the workbench 3 with one suitable for different tools, it is re-secured with bolts, enabling quick replacement and maintenance of the workbench 3.
[0037] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
