Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining technology, specifically to an auxiliary clamping fixture for machining bench drills. Background Technology
[0002] A bench drill is a small drilling machine tool commonly used for drilling, reaming, countersinking, and tapping of materials such as metal and wood. It is usually mounted on a table, has a compact structure, is easy to operate, and is suitable for single-piece or small-batch production and maintenance. A bench drill mainly consists of a motor, spindle, drill bit clamping device, worktable, and base. The motor drives the spindle to rotate the drill bit, and the workpiece can be flexibly processed by adjusting the height and position of the worktable.
[0003] Existing bench drills typically come with only one work platform when shipped from the factory. However, when drilling workpieces, the work platform cannot hold the material in place, which can easily cause the material to shift, affecting the accuracy of material processing. At the same time, there is the problem of material splashing, which poses a safety hazard. Furthermore, the bench drill platform cannot clean up the debris generated during workpiece processing. Over time, the accumulated debris will corrode the worktable, increasing the frequency of maintenance. Unremoved debris may scratch the surface of the workpiece, causing irreversible damage, especially to precision-machined parts. Utility Model Content

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0023] Please see Figure 1-4 As shown, an auxiliary clamping fixture for a machining bench drill includes a support plate 1 and a housing 2. The housing 2 is fixed to the top of the support plate 1. Two sets of first clamping plates 3 are fixed to the top of the housing 2. A bidirectional screw 4 is rotatably connected to the inner wall of the housing 2. Two sets of threaded blocks 5 are threaded to the outer side of the bidirectional screw 4. Two sets of threads in opposite directions are provided on the outer side of the bidirectional screw 4. Rotation of the bidirectional screw 4 can drive the two sets of threaded blocks 5 to move in opposite directions. A guide plate 6 is fixed to the top of the threaded blocks 5. A second clamping plate 7 for clamping the workpiece is fixed to one side of the guide plate 6. The first clamping plates 3 and the second clamping plates 7 achieve the effect of clamping and fixing the workpiece, improving the stability of workpiece processing. It can also clamp two sets of the same workpiece at the same time, improving processing efficiency.
[0024] The chassis 8 is located at the bottom of the support plate 1. A rotating rod 9 is rotatably connected to the top of the chassis 8. The top of the rotating rod 9 is fixedly connected to the bottom of the support plate 1. A guide frame 10 is fixed to the outside of the rotating rod 9. A guide groove 11 is provided on the inner wall of the guide frame 10. A drive block 12 that drives the guide frame 10 to rotate is slidably connected to the inner wall of the guide groove 11. The bottom of the guide frame 10 is rotatably connected to the chassis 8. By sliding the drive block 12 inside the guide groove 11, the guide frame 10 and the rotating rod 9 can be pulled to rotate, thereby driving the support plate 1 and the housing 2 to rotate. This achieves the effect of driving the clamped workpiece to rotate, which facilitates the subsequent adjustment of the workpiece's processing angle.
[0025] The flow guide 13 is fixed to the outside of the housing 2 and is used to guide and discharge the debris generated during processing. A base 14 is fixed to the top of the support plate 1, and a box 15 is fixed to the top of the base 14. A guide rod 16 is fixed to the inner wall of the box 15, and a support frame 17 is slidably connected to the outside of the guide rod 16. A collection box 18 for collecting debris generated during processing is installed on the top of the support frame 17. The flow guide 13 allows the debris generated during processing to be discharged into the collection box 18 for storage, avoiding the problem of debris being difficult to clean. A spring 31 is provided on the outside of the guide rod 16, and a spring 31 is slidably connected to the inner wall of the base 14. The limiting frame 32, which limits the support frame 17, is pulled to move left and right inside the base 14, so that the limiting frame 32 presses against the top of both sides of the support frame 17, thereby limiting and fixing the support frame 17. When it is necessary to clean the debris inside the collection box 18, first pull the limiting frame 32 to slide left and right inside the base 14, so that the limiting frame 32 is separated from the support frame 17. At this time, the support frame 17 loses its limit and, under the reaction force of the spring 31, drives the support frame 17 to slide upward on the outside of the guide rod 16, so that the support frame 17 drives the collection box 18 to rise, making it convenient to remove the collection box 18 for cleaning the debris.
[0026] One end of the bidirectional screw 4 is fixed with a handle 19. Anti-slip pads 20 are installed on one side of both the first clamping plate 3 and the second clamping plate 7. The anti-slip pads 20 are made of silicone, which improves the stability of workpiece clamping.
[0027] The inner wall of the housing 2 is fixed with a limiting rod 21 for guiding the threaded block 5. The outer side of the limiting rod 21 is slidably connected to the inner wall of the threaded block 5. The top of the housing 2 is provided with a sliding groove 22 for guiding the guide plate 6. The inner wall of the sliding groove 22 is slidably connected to the outer side of the guide plate 6.
[0028] A support plate 33 is provided on the top of the chassis 8. The inner wall of the support plate 33 is rotatably connected to the outer side of the rotating rod 9 through a rotating shaft. A mounting bracket 23 is fixed at the bottom of the support plate 33. A drive motor 24 is installed on the inner wall of the mounting bracket 23. A fixing block 25 is fixed at the output end of the drive motor 24 to drive the drive block 12 to rotate. The bottom of the fixing block 25 is fixedly connected to the top of the drive block 12.
[0029] A connecting plate 26 is fixed to the outside of the fixed block 25, and a limiting plate 27 is fixed to the top of the guide frame 10. The outside of the connecting plate 26 is slidably connected to the inner wall of the limiting plate 27, which reduces the inertia of the fixed block 25 when it rotates and improves the stability of the rotating rod 9.
[0030] Multiple sets of support blocks 28 are fixed to the outer side of the chassis 8. The inner wall of the support block 28 is threaded with mounting bolts 29. The support block 28 is installed on the workbench by mounting bolts 29 to improve the stability of the device. A support rod 30 is fixed to the top of the chassis 8. The top of the support rod 30 is fixed to the bottom of the support plate 33.
[0031] Working Principle: In use, this device allows two identical workpieces to be placed on one side of the first clamping plate 3 and the second clamping plate 7, respectively. Rotating the handle 19 drives the bidirectional screw 4 to rotate, causing the two sets of threaded blocks 5 to move in opposite directions. This allows the threaded blocks 5 to slide outside the limiting rod 21, causing the guide plate 6 to slide inside the slide groove 22. This, in turn, moves the second clamping plate 7 to clamp the workpiece, improving the stability of the workpiece processing. The anti-slip pad 20 further enhances the stability of workpiece clamping and allows for the simultaneous clamping of two identical workpieces, improving processing efficiency. The drive motor 24 drives the fixed block 25 and the drive block 12 to rotate, causing the drive block 12 to slide inside the guide groove 11. This pulls the guide frame 10 and the rotating rod 9 to rotate, which in turn rotates the support plate 1 and the housing 2. This achieves the effect of rotating the clamped workpiece, facilitating subsequent adjustment of the workpiece's processing angle. The guide frame 13 can discharge the debris generated during processing into the collection box 18 for storage, avoiding the problem of debris being difficult to clean. Pulling the limiting frame 32 and moving it left and right inside the base 14 causes the limiting frame 32 to press against the top of both sides of the support frame 17, thereby limiting and fixing the support frame 17. When it is necessary to clean the debris inside the collection box 18, first pull the limiting frame 32 and slide it left and right inside the base 14, causing the limiting frame 32 to disengage from the support frame 17. At this time, the support frame 17 loses its limiting position and, under the reaction force of the spring 31, drives the support frame 17 to slide upward outside the guide rod 16, causing the support frame 17 to lift the collection box 18, making it convenient to remove the collection box 18 for subsequent cleaning of debris.
