Abstract
Description
Technical Field
[0001] This utility model relates to the field of taper shank drill straightening technology, and in particular to a taper shank drill pressure straightening tool. Background Technology
[0002] The taper shank drill pressure straightening fixture is a tool used to correct the straightness of a taper shank drill. Taper shank drills are commonly used hole-making tools, named for their tapered shank structure, and are widely used in machinery manufacturing, mold making, metal processing and other fields.
[0003] Tapered shank drills may bend and deform during use and storage. If they are not straightened in time, they will directly affect the machining quality and tool life. However, existing straightening fixtures cannot be flipped over during use, which leads to frequent adjustments of the workpiece position for repair, reducing the ease of use of the straightening fixtures.
[0004] To address this issue, a pressure straightening tool for taper shank drills is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a pressure straightening tool for a taper shank drill, which aims to improve the existing straightening tool's inability to rotate the taper shank drill during use, resulting in frequent adjustments to the object's position and reduced ease of use.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A pressure straightening fixture for a taper shank drill includes a worktable. Supports are fixedly connected to the left and right sides of the top of the worktable. A rotating rod is movably connected to the inner cavity of the support via bearings. A clamping mechanism is fixedly sleeved on the surface of the rotating rod. The clamping mechanism includes a fixing block, an operating box, and an L-shaped clamping plate. The fixing block is fixedly sleeved on the surface of the rotating rod. The operating box is fixedly connected to the front end of the fixing block. L-shaped clamping plates are slidably connected to the left and right sides of the front end of the operating box. Adjustment mechanisms are movably connected to the left and right sides of the inner wall of the operating box via bearing seats.
[0008] With the above technical solution, the material of the hand-held tapered shank drill is placed between the L-shaped clamps. Then, the mechanical parts inside the operating box work to bring the L-shaped clamps closer together. The L-shaped clamps clamp and fix the lower end of the tapered shank drill, while the exposed upper end of the tapered shank drill is manually straightened. This achieves the straightening operation after fixing the tapered shank drill.
[0009] As a further description of the above technical solution: the adjustment mechanism includes a screw, an H-shaped plate, and a clamping plate. The left and right sides of the inner wall of the operation box are movably connected to the screw via bearing seats. The surface of the screw is movably fitted with an H-shaped plate via threads. The front end of the H-shaped plate is fixedly connected to the clamping plate. The back end of the L-shaped clamping plate extends into the interior of the operation box and is fixedly connected to the front end of the clamping plate. The top of the operation box is movably connected to the operation mechanism via bearings.
[0010] Through the above technical solution, the setting of the adjustment mechanism can make the screw rotate under the influence of external force. The rotation of the screw causes the H-shaped plate to rotate out along the thread direction. The H-shaped plates move closer to each other and drive the clamping plate to move accordingly. The movement of the clamping plate drives the L-shaped clamping plate to move synchronously, so as to realize the operation of the L-shaped clamping plate to fix or loosen the material of the taper shank drill.
[0011] As a further description of the above technical solution: the operating mechanism includes a throttle, a gear and a bevel gear. The top of the operating box is movably connected to the throttle via a bearing. The bottom of the throttle extends through the interior of the operating box and is fixedly connected to the gear. The inner side of the screw is fixedly connected to the bevel gear. The top of the bevel gear meshes with the two sides of the bottom of the gear. A flipping mechanism is fixedly connected to the left side of the top of the worktable.
[0012] Through the above technical solution, the operating mechanism is designed to allow manual rotation of the throttle, which in turn drives the gear to rotate clockwise. The rotation of the gear then synchronously drives the bevel gear to rotate, which in turn drives the screw to rotate, thereby achieving the transmission of mechanical power.
[0013] As a further description of the above technical solution: the flipping mechanism includes a frame, a push plate, a toothed plate, and a toothed disc. The frame is fixedly connected to the left side of the top of the worktable, the push plate is slidably connected to the top of the frame, the toothed plate is fixedly connected to the right side of the push plate, and the toothed disc is fixedly connected to the left side of the rotating rod. The bottom of the toothed disc is meshed with the top of the toothed plate.
[0014] With the above technical solution, the flipping mechanism can be set up so that the push plate can be pushed forward by hand. The push plate moves forward and drives the toothed plate to move. The push plate moves horizontally along the surface of the frame. Finally, during the forward movement of the toothed plate, the toothed plate drives the toothed disc to rotate counterclockwise. The rotation of the toothed disc drives the rotating rod, the fixed block and the operating box to flip to the other end as a whole, completing the mechanical flipping and facilitating the straightening operation of the upper and lower ends of the taper shank drill.
[0015] As a further description of the above technical solution: a sliding groove is provided at the top of the frame and at the position corresponding to the push plate, and the sliding groove is used in conjunction with the push plate.
[0016] Through the above technical solution, the slide groove enables the push plate to move back and forth inside the frame, while also serving as a limit, preventing the push plate from shifting during movement.
[0017] As a further description of the above technical solution: a handle is fixedly connected to the back end of the push plate, and the handle is used in conjunction with the push plate.
[0018] Through the above technical solution, the handle design can assist the push plate in its operation and facilitate hand operation, thus avoiding the inconvenience of the user's operation due to the lack of a force point on the push plate.
[0019] As a further description of the above technical solution: a dustproof plate is fixedly connected to the left side of the top of the workbench, and the dustproof plate is used in conjunction with the toothed plate.
[0020] Through the above technical solution, the dustproof plate can assist the toothed plate in its work and also serve as a shield, preventing the toothed plate from being affected by dust and the toothed plate from getting stuck.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, by setting up a fixing block, an operation box, and an L-shaped clamp, the user can hold the material of the conical shank drill between the L-shaped clamps and then drive the mechanical parts inside the operation box to move, so that the L-shaped clamps move closer to each other. The L-shaped clamps clamp and fix the center point of the conical shank drill. After the conical shank drill is fixed, the user can straighten the upper end of the conical shank drill. Alternatively, the rotation of the rotating rod can drive the fixing block, the operation box, and the L-shaped clamp to flip and adjust the surface as a whole, so as to straighten the lower end of the conical shank drill without adjusting the material, thus achieving the function of flipping assistance to facilitate user operation.
[0023] 2. In this utility model, the screw, H-shaped plate and clamping plate are arranged so that the screw can rotate and drive the H-shaped plate to rotate out in the direction of the thread. The rotation of the H-shaped plate drives the clamping plate to move along with it. The movement of the clamping plate drives the L-shaped clamping plate to move closer and closer at the same time, so as to fix the material of the tapered shank drill by moving the two clamping plates closer or further apart. This allows the tapered shank drill to be flipped without adjusting its position, and the straightening operation of the upper and lower ends of the tapered shank drill can be achieved.

[0031] 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.
[0032] Reference Figure 1-5 This utility model provides an embodiment of a pressure straightening fixture for a taper shank drill, comprising a workbench 1, with supports 2 fixedly connected to the left and right sides of the top of the workbench 1. A rotating rod 3 is movably connected to the inner cavity of the support 2 via bearings. A clamping mechanism 4 is fixedly sleeved on the surface of the rotating rod 3. The clamping mechanism 4 includes a fixing block 41, an operation box 42, and an L-shaped clamping plate 43. The fixing block 41 is fixedly sleeved on the surface of the rotating rod 3. The operation box 42 is fixedly connected to the front end of the fixing block 41. The L-shaped clamping plate 43 is slidably connected to the left and right sides of the front end of the operation box 42. An adjustment mechanism 5 is movably connected to the left and right sides of the inner wall of the operation box 42 via bearing seats. In use, the taper shank drill material is held between the L-shaped clamping plates 43. Then, the mechanical parts inside the operation box 42 are used to move the L-shaped clamping plates 43 closer together. The L-shaped clamping plates 43 clamp and fix the lower end of the taper shank drill, while the exposed upper end of the taper shank drill is manually straightened, thereby realizing the straightening operation after fixing the taper shank drill.
[0033] Reference Figure 1-5The adjusting mechanism 5 includes a screw 51, an H-shaped plate 52, and a clamping plate 53. The left and right sides of the inner wall of the operating box 42 are movably connected to the screw 51 via bearing seats. The surface of the screw 51 is threadedly fitted with the H-shaped plate 52. The front end of the H-shaped plate 52 is fixedly connected to the clamping plate 53. The back end of the L-shaped clamping plate 43 extends into the interior of the operating box 42 and is fixedly connected to the front end of the clamping plate 53. The top of the operating box 42 is movably connected to the operating mechanism 6 via bearings. Through the adjustment mechanism 5, the screw 51 can be rotated under external force. The rotation of the screw 51 causes the H-shaped plate 52 to unscrew along the thread direction. The H-shaped plates 52 move closer together, causing the clamping plate 53 to move accordingly. The movement of the clamping plate 53 then causes the L-shaped clamping plate 43 to move synchronously, thus achieving the operating mechanism 6. L-shaped clamp 43 fixes or releases material from the taper shank drill. The operating mechanism 6 includes a handle 61, a gear 62, and a bevel gear 63. The top of the operating box 42 is movably connected to the handle 61 via a bearing. The bottom of the handle 61 extends through the interior of the operating box 42 and is fixedly connected to the gear 62. The inner side of the screw 51 is fixedly connected to the bevel gear 63. The top of the bevel gear 63 meshes with the two sides of the bottom of the gear 62. A flipping mechanism 7 is fixedly connected to the left side of the top of the worktable 1. Through the setting of the operating mechanism 6, the handle 61 can be manually rotated. The rotation of the handle 61 drives the gear 62 to rotate clockwise. The rotation of the gear 62 synchronously drives the bevel gear 63 to rotate. The rotation of the bevel gear 63 drives the screw 51 to rotate, thereby realizing the transmission of mechanical power.
[0034] Reference Figure 1-5The flipping mechanism 7 includes a frame 71, a push plate 72, a toothed plate 73, and a toothed disc 74. The frame 71 is fixedly connected to the left side of the top of the worktable 1. The push plate 72 is slidably connected to the top of the frame 71. The toothed plate 73 is fixedly connected to the right side of the push plate 72. The toothed disc 74 is fixedly connected to the left side of the rotating rod 3. The bottom of the toothed disc 74 meshes with the top of the toothed plate 73. Through the flipping mechanism 7, the push plate 72 can be pushed forward by hand, causing the toothed plate 73 to move accordingly. The push plate 72 moves horizontally along the surface of the frame 71. Finally, as the toothed plate 73 moves forward, it causes the toothed disc 74 to rotate counterclockwise. The rotation of the toothed disc 74 causes the rotating rod 3, the fixed block 41, and the operating box 42 to flip to the other end, completing the mechanical flipping for direct straightening of the upper and lower ends of the taper shank drill. The top of the frame 71... A sliding groove 8 is provided at the position corresponding to the push plate 72. The sliding groove 8 works in conjunction with the push plate 72. The sliding groove 8 allows the push plate 72 to move back and forth inside the frame 71, and also serves as a limit to prevent the push plate 72 from deviating during movement. A handle 9 is fixedly connected to the back end of the push plate 72. The handle 9 works in conjunction with the push plate 72. The handle 9 assists the push plate 72 in its operation and facilitates hand operation, preventing the push plate 72 from being inconvenient to operate due to the lack of a force point. A dustproof plate 10 is fixedly connected to the left side of the top of the workbench 1. The dustproof plate 10 works in conjunction with the toothed plate 73. The dustproof plate 10 assists the toothed plate 73 in its operation and also serves as a shield to prevent the toothed plate 73 from being affected by dust and from jamming with the toothed disc 74.
[0035] Working principle: During use, the hand-held taper shank drill body is positioned between L-shaped clamps 43. Then, the handle 61 is manually rotated. Rotation of handle 61 drives gear 62, which in turn drives bevel gear 63. The bevel gear 63, in turn, drives screw 51 to rotate synchronously. The rotation of screw 51 causes H-shaped plate 52 to unscrew along the thread direction. The unscrewing of H-shaped plate 52 causes clamping plate 53 and L-shaped clamps 43 to move synchronously. As the two L-shaped clamps 43 approach each other, they clamp and fix the center of the taper shank drill body, exposing the upper end of the taper shank drill for manual straightening. When it is necessary to straighten the lower end of the taper shank drill... When straightening the end, push the handle 9 forward. The forward movement of the handle 9 causes the push plate 72 to move forward. The push plate 72 moves horizontally along the slide groove 8 on the surface of the frame 71. Then, the forward movement of the push plate 72 causes the toothed plate 73 to move along with it. During the movement of the toothed plate 73, the toothed disc 74 rotates counterclockwise. The rotation of the toothed disc 74 causes the rotating rod 3 to rotate. The rotation of the rotating rod 3 causes the fixing block 41 and the operation box 42 to flip and adjust as a whole. This changes the position of the tapered shank drill held by the L-shaped clamp 43 from the top end to the bottom end, making it convenient for the user to perform straightening operations directly at both ends without adjusting the material.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
