Description

Technical Field

[0001] This utility model relates to the field of tapping machine technology, specifically to a tapping machine for adjusting screws. Background Technology

[0002] Adjusting screws are commonly used components in the mechanical field. Their machining process requires tapping a screw hole wall to produce internal threads. The clamping stability and structural reliability of the tapping machine directly affect the machining accuracy and efficiency of the screw. Currently, most tapping machines for adjusting screws use fixed-size grooves to hold the screw, lacking adaptively adjustable clamping components. When machining adjusting screws of different diameters or lengths, frequent changes to the clamping molds are necessary, which is not only cumbersome but also prone to loosening due to calibration deviations after mold changes. This can lead to screw displacement during tapping, resulting in decreased thread accuracy or even scrapping. Some tapping machines also have poorly designed overall support structures, lacking stable mounting foundations for the screw placement components. Vibration during tapping can cause structural displacement, further affecting tapping accuracy. Furthermore, the poor linkage between the control components and the tapping device makes it impossible to quickly adjust tapping parameters to adapt to different screw machining requirements, hindering the production of high-precision adjusting screws in batches. Therefore, improvements are needed. Utility Model Content

[0015] like Figures 1-6 As shown, this invention illustrates a tapping machine for adjusting screws according to one embodiment of the present invention. It includes a platform 1, a tapping device 2 disposed on the upper left end of the platform 1, a side plate 3 disposed on the upper right end of the platform 1, and an adjusting mechanism 4 disposed on the outer side of the side plate 3. The adjusting mechanism 4 includes two gears 44 rotatably mounted on the rear side of the side plate 3. A rotating shaft 45, extending through to the front side of the side plate 3, is welded to the front end of the two gears 44. A disc 46 is bolted to the front end of the rotating shaft 45. Placement grooves 47 are evenly distributed on the surface of the disc 46. A fixing mechanism 6 is disposed inside the placement grooves 47. The fixing mechanism 6 includes a rectangular groove 61 formed inside the placement groove 47. A rectangular plate 62 is slidably mounted inside the rectangular groove 61. A telescopic spring 66 is elastically installed between the inner side of the rectangular plate 62 and the inner side of the rectangular groove 61. An arc-shaped plate 63, slidably connected inside the placement groove 47, is welded to the front end of the rectangular plate 62. A control plate 5 is bolted to the outer side of the side plate 3. The workpiece to be processed is placed in the placement groove 47 of the disc 46. After the fixing mechanism 6 clamps and fixes it, the tapping device 2 starts and taps the workpiece in the placement groove 47. During the tapping process, the rectangular plate 62 can slide along the rectangular groove 61. The telescopic spring 66 generates elastic force to push the rectangular plate 62 to drive the arc plate 63 to stick tightly to the workpiece, so as to achieve stable clamping. The control plate 5 is used to control the start and stop of the tapping device 2 and the tapping parameters. The platform 1 provides support for the overall structure, and the side plate 3 provides the installation base for the adjustment mechanism 4. By setting a fixing mechanism 6 consisting of a rectangular slot 61, a rectangular plate 62, an arc plate 63, and a telescopic spring 66 in the placement slot 47 of the disc 46, the elastic force of the telescopic spring 66 pushes the rectangular plate 62 to drive the arc plate 63 to tightly adhere to the workpiece, thus achieving adaptive and stable clamping of the adjusting screw. At the same time, the control board 5 controls the start and stop of the tapping device 2 and the tapping parameters, simplifying the operation process. The platform 1 provides stable support for the overall structure, and the side plate 3 provides a reliable installation base for the adjusting mechanism 4, ensuring the stability of the tapping process. This solves the technical problem in the prior art that the clamping mechanism cannot adaptively adapt to the screw specifications when the adjusting screw is tapping, and that the clamping is prone to loosening, resulting in low tapping accuracy. like Figures 1-6As shown, on the other hand, this utility model also provides a tapping machine for adjusting screws, wherein an adjusting disc 49 is movably sleeved on the outer side of one side of the rotating shaft 45, a connecting plate 410 is uniformly welded on the outer side of the adjusting disc 49, an adjusting cylinder 411 is welded to the front side of the top of the connecting plate 410, a bottom ring block 414 is welded to the front side of the adjusting disc 49, a connecting block 415 is welded to the front side of the bottom ring block 414, a beveled elastic clamping ring 416 is glued to the front end of the connecting block 415, an outer ring block 412 is welded to the outer side of the bottom ring block 414, a threaded groove 417 is opened on the inner side of the top of the outer ring block 412, a threaded ring 418 is threaded on the inner side of the threaded groove 417, a ring-shaped knob 413 is welded to the top of the threaded ring 418, a retaining ring 419 is welded to the inner end of the threaded ring 418, and a scale groove 48 is provided on the outer side of the rotating shaft 45. In some examples, when adjusting the position of the adjusting cylinder 411 in the placement groove 47, the adjusting disc 49 is pushed to slide along the rotating shaft 45. The adjusting disc 49 drives the connecting plate 410 to move the adjusting cylinder 411 synchronously. After the position is determined, the annular knob 413 is rotated to drive the threaded ring 418 to rotate along the threaded groove 417. The threaded ring 418 pushes the retaining ring 419 to squeeze the inclined elastic clamping ring 416. The inclined elastic clamping ring 416 contracts and fits tightly against the rotating shaft 45, thereby fixing the adjusting disc 49 and the rotating shaft 45 relatively. The scale groove 48 is used to assist in calibrating the moving position of the adjusting disc 49. The bottom ring block 414 and the connecting block 415 provide installation support for the inclined elastic clamping ring 416, and the outer ring block 412 provides an installation base for the threaded ring 418. like Figures 1-6 As shown, on the other hand, this utility model also provides a tapping machine for adjusting screws, in which two gears 44 are connected by a chain 43, a mounting bracket 41 is bolted on the rear side of the side plate 3, a servo motor 42 is bolted on the outer side of the mounting bracket 41, and the output end of the servo motor 42 is bolted on the rear side of one of the gears 44. In some examples, after the servo motor 42 is started, its output drives the gear 44 connected to it to rotate. The gear 44 drives another gear 44 to rotate synchronously through the chain 43. The two gears 44 drive the corresponding rotating shaft 45 to rotate, and the rotating shaft 45 drives the disc 46 to rotate, so that the workpiece to be processed in the placement slot 47 is transferred to the bottom of the tapping device 2 for tapping. The mounting bracket 41 provides mounting and fixing support for the servo motor 42. like Figures 1-6 As shown, on the other hand, this utility model also provides a tapping machine for adjusting screws, wherein sliding grooves 64 are provided on both sides of the rectangular groove 61, and sliders 65 that are slidably connected inside the sliding grooves 64 are welded to both sides of the bottom end of the rectangular plate 62. In some examples, when the rectangular plate 62 slides along the rectangular groove 61, the rectangular plate 62 drives the slider 65 to slide synchronously along the slide groove 64; the cooperation between the slider 65 and the slide groove 64 restricts the sliding direction of the rectangular plate 62, avoids the rectangular plate 62 from deviating when sliding, and ensures that the rectangular plate 62 drives the arc plate 63 to stably clamp the workpiece to be processed. like Figures 1-6 As shown, on the other hand, this utility model also provides a tapping machine for adjusting screws, wherein the number of connecting plates 410 is equal to the number of placement slots 47, and each adjusting cylinder 411 is disposed inside the corresponding placement slot 47. In some examples, the number of connecting plates 410 and placement slots 47 is the same, and the adjusting cylinders 411 correspond one-to-one with the placement slots 47. When the adjusting plate 49 drives the connecting plate 410 to move, each connecting plate 410 can drive the corresponding adjusting cylinder 411 to enter or exit the placement slot 47 synchronously, ensuring that the positioning reference of the workpiece to be processed in all placement slots 47 is consistent. like Figures 1-6 As shown, on the other hand, this utility model also provides a tapping machine for adjusting screws, wherein a beveled elastic clamping ring 416 is coaxially sleeved on the outside of the rotating shaft 45, and the inner wall of the beveled elastic clamping ring 416 is in contact with the outer wall of the rotating shaft 45, and a retaining ring 419 is located on the outside of the beveled elastic clamping ring 416, and the inner wall of the retaining ring 419 is adapted to the outer wall of the beveled elastic clamping ring 416. In some examples, the inclined elastic clamping ring 416 is coaxially sleeved with the rotating shaft 45 to ensure that the inclined elastic clamping ring 416 can contract evenly when subjected to force; when the retaining ring 419 squeezes the inclined elastic clamping ring 416, the inner wall of the inclined elastic clamping ring 416 is in close contact with the outer wall of the rotating shaft 45, increasing the friction between the inclined elastic clamping ring 416 and the rotating shaft 45, thereby fixing the adjusting plate 49 to the rotating shaft 45; the inner wall of the retaining ring 419 is adapted to the outer wall of the inclined elastic clamping ring 416 to ensure that the retaining ring 419 can stably squeeze the inclined elastic clamping ring 416. like Figures 1-6 As shown, on the other hand, this utility model also provides a tapping machine for adjusting screws, wherein the outer ring block 412 is coaxially fixed to the outside of the bottom ring block 414, the screw groove 417 is opened along the radial direction of the outer ring block 412, and the axis of the screw groove 417 is perpendicular to the axis of the connecting block 415, and the outer wall of the threaded ring 418 is threadedly fitted to the inner wall of the screw groove 417. In some examples, the outer ring block 412 is coaxially fixed with the bottom ring block 414 to ensure the stability of the opening direction of the threaded groove 417; the threaded groove 417 is radially opened along the outer ring block 412, so that the threaded ring 418 can move radially when rotating along the threaded groove 417, thereby pushing the retaining ring 419; the outer wall of the threaded ring 418 is threadedly fitted with the inner wall of the threaded groove 417 to ensure that the threaded ring 418 can move stably when rotating; the axis of the threaded groove 417 is perpendicular to the axis of the connecting block 415 to avoid interference between the threaded ring 418 and the connecting block 415 when moving. like Figures 1-6 As shown, on the other hand, this utility model also provides a tapping machine for adjusting screws, wherein a rectangular groove 61 is opened radially along the placement groove 47, the outer wall of the rectangular plate 62 is slidably fitted with the inner wall of the rectangular groove 61, the arc surface of the arc plate 63 faces the axial direction of the placement groove 47, and the outer wall of the arc plate 63 is slidably adapted to the inner wall of the placement groove 47. In some examples, the rectangular groove 61 is radially opened along the placement groove 47, so that when the rectangular plate 62 slides along the rectangular groove 61, it can drive the arc plate 63 to move closer to or away from the workpiece in the placement groove 47; the rectangular plate 62 slides and fits with the rectangular groove 61 to ensure the sliding stability of the rectangular plate 62; the arc surface of the arc plate 63 faces the axis of the placement groove 47, so that the arc plate 63 can fit tightly with the outer wall of the workpiece, enhancing the clamping stability; the arc plate 63 slides and adapts to the placement groove 47 to avoid jamming when the arc plate 63 moves.

[0016] like Figures 1-6 As shown, on the other hand, this utility model also provides a tapping machine for adjusting screws, wherein the slide groove 64 is opened along the length direction of the rectangular groove 61, and the slide groove 64 is symmetrically distributed on both sides of the rectangular groove 61, and the outer wall of the slider 65 slides and fits against the inner wall of the slide groove 64. In some examples, the slide groove 64 is opened along the length of the rectangular groove 61 and is symmetrically distributed, so that when the slider 65 slides along the slide groove 64, it can keep the sliding direction of the rectangular plate 62 consistent; the slider 65 slides and fits into the slide groove 64, ensuring that the slider 65 slides smoothly, further restricting the sliding posture of the rectangular plate 62 and preventing the rectangular plate 62 from tilting in the rectangular groove 61. like Figures 1-6 As shown, on the other hand, this utility model also provides a tapping machine for adjusting screws. The mounting bracket 41 is fixed to the rear end face of the side plate 3. The axis of the servo motor 42 is parallel to the axis of the gear 44. The chain 43 is sleeved on the outside of the two gears 44, and the inner wall of the chain 43 is meshed with the tooth surface of the gear 44. In some examples, the mounting bracket 41 is fixed to the rear side of the side plate 3 to provide stable support for the servo motor 42; the axis of the servo motor 42 is parallel to the axis of the gear 44 to ensure that the output end of the servo motor 42 can accurately drive the gear 44 to rotate; the chain 43 is fitted with two gears 44 and the inner wall meshes with the tooth surface of the gear 44 to ensure that when the servo motor 42 drives one gear 44 to rotate, the other gear 44 can rotate synchronously and stably. Working principle and usage process of this utility model: According to the length of the adjusting screw to be processed, the adjusting disc 49 is pushed to move along the outer side of the rotating shaft 45. When the adjusting disc 49 moves inward, it drives the adjusting cylinder 411 to move synchronously through the connecting plate 410, so that the adjusting cylinder 411 is inserted into the placement groove 47 of the disc 46 until the position of the adjusting cylinder 411 matches the length of the screw. Then, the annular knob 413 is rotated to drive the threaded ring 418 to rotate along the threaded groove 417 of the outer ring block 412. The threaded ring 418 pushes the retaining ring 419 to move to the right. The retaining ring 419 squeezes the outer wall of the inclined elastic clamping ring 416, so that the inclined elastic clamping ring 416 contracts inward and fits tightly against the outer side of the rotating shaft 45, thus completing the position fixation of the adjusting cylinder 411. The servo motor 42 is started through the control board 5. The output end of the servo motor 42 drives the gear 44 on one side. The rotating gear 44 on the other side is synchronously driven by the chain 43, which in turn drives the rotating shaft 45 and the disc 46 to rotate synchronously. When a certain placement slot 47 rotates to the upper loading position, the adjustment screw to be processed is placed into the placement slot 47. The motor continues to run, driving the disc 46 to rotate, so that the placement slot 47 containing the screw rotates with the disc 46 to the closed clamping state. During the closing process, the outer wall of the screw presses the arc plate 63, causing the rectangular plate 62 to slide along the rectangular groove 61. The rectangular plate 62 presses the telescopic spring 66 to store elastic potential energy. The rebound force of the telescopic spring 66 pushes the rectangular plate 62 and the arc plate 63 in the opposite direction, so that the arc plate 63 fits tightly against the outer wall of the screw. At the same time, the sliders 65 on both sides of the rectangular plate 62 slide stably along the sliding groove 64 to realize the elastic clamping and fixing of the screw.
