Description

Technical Field

[0001] This utility model relates to the field of tapping machine technology, and in particular to a tapping machine base. Background Technology

[0002] In industrial production, tapping is an extremely important process used to manufacture various parts with internal threads. It is widely used in many fields such as machinery manufacturing, automobiles, and aerospace. However, existing tapping machine tools have revealed many problems in actual use, which urgently need to be solved.

[0003] In the workpiece clamping stage, some traditional tapping machine tool bases use a single positioning method with insufficient precision, relying on manual alignment, which can easily introduce large errors and make it difficult to ensure that the center of the workpiece is accurately aligned with the machining area. In terms of clamping stability, many machine tool bases use single-point or simple double-sided clamping methods. During the tapping process, the workpiece is easily offset or deformed due to external forces such as cutting forces and vibrations, resulting in quality problems such as positional deviation and uneven pitch of the machined threaded holes, which seriously affect product performance and yield.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Reference Figures 1 to 4 As shown, this utility model provides a technical solution: a tapping machine tool base, including a support base 1, a mounting groove 2 on the surface of the support base 1, a processing table 3 above the mounting groove 2, the lower end of the processing table 3 being fixedly connected to the surface of the support base 1, and a rotating groove 5 on the surface of the processing table 3, a clamping plate 6 rotatably connected to the inner wall of the rotating groove 5, a gear 8 fixedly connected to the lower end of the clamping plate 6, a gear ring 9 meshing with the surface of the gear 8, a reinforcing frame 10 fixedly connected to the inner side of the gear ring 9, and the top of the reinforcing frame 10 rotatably connected to the lower surface of the processing table 3. When it is necessary to tap the workpiece... During operation, the workpiece is first placed on the machining table 3. Then, the gear ring 9 drives three sets of equidistantly distributed gears 8 and clamping plates 6 to rotate, achieving multi-point symmetrical clamping of the workpiece. Compared with traditional single-point clamping, it can effectively distribute the force and avoid workpiece displacement or deformation caused by uneven force at a single point, ensuring the accuracy of the workpiece position during tapping. At the same time, the reinforcing frame 10 on the inner side of the gear ring 9 can enhance the overall structural rigidity of the gear ring 9, effectively preventing deformation of the gear ring 9 during transmission, ensuring the accuracy of meshing between the gear 8 and the gear ring 9, thereby improving transmission accuracy and reducing machining errors caused by deformation of transmission components.

[0025] Reference Figure 2 and Figure 3As shown in this embodiment, the number of clamping plates 6 and gears 8 are both set to three sets. The three sets of clamping plates 6 and gears 8 correspond one-to-one and are distributed in an equidistant array on the surface of the processing table 3. The three sets of equidistantly distributed clamping plates 6 and gears 8 are linked through the gear ring 9 to achieve symmetrical and uniform clamping of the workpiece, avoiding displacement and deformation caused by single-point force. The lower end of the reinforcing frame 10 is fixedly connected to a worm gear disk 11. A worm 12 is meshed with one side of the worm gear disk 11. The two ends of the worm 12 are rotatably connected to fixed plates 13. The lower end of the fixed plate 13 is fixedly connected to the inner wall of the mounting groove 2. The worm gear 12 drives the worm wheel 11 to rotate. When the worm wheel 11 rotates, it drives the upper gear ring 9 to rotate, thus achieving the effect of driving the gear ring 9 to rotate. At the same time, the worm gear 12 transmission has a self-locking characteristic, which can lock the position after clamping the workpiece to prevent the clamping from loosening due to vibration during tapping. One end of the three sets of clamping plates 6 is fixedly connected to a clamping block 7. The surface of the three clamping blocks 7 is provided with rubber pads. By providing rubber pads on the surface of the clamping blocks 7, the friction can be increased to prevent the workpiece from sliding, and at the same time, the metal clamping blocks 7 can be prevented from directly contacting the workpiece surface and causing scratches.

[0026] Reference Figure 3 and Figure 4 As shown, specifically, the cross-section of the reinforcing frame 10 is Y-shaped. One end of the worm gear 12 is fixedly connected to a turntable 14. The surface of the processing table 3 is provided with a placement groove 4, which is located at the center of the processing table 3. The turntable 14 can drive the worm gear 12 to rotate. The placement groove 4 facilitates the placement of workpieces by the operator. The surface of the processing table 3 is provided with three sets of guide grooves 15. The inner walls of the three sets of guide grooves 15 are slidably connected to guide rods 16. The top of the guide rods 16 is fixedly connected to the lower surface of the clamping block 7. The slidable connection between the guide grooves 15 and the guide rods 16 guides the rotation of the clamping plate 6 and the clamping block 7, preventing deviation during clamping and ensuring the positioning accuracy of the clamped workpiece.

[0027] Working principle: During use, the operator places the workpiece to be processed on the surface of the processing table 3 and uses the placement groove 4 in the center of the processing table 3 for initial positioning. By rotating the turntable 14 at one end of the worm gear 12, the worm gear 12 drives the worm wheel 11 to rotate, which in turn causes the gear ring 9, which is fixedly connected to the worm wheel 11 through the reinforcing frame 10, to rotate. The gear ring 9 meshes and drives three sets of equidistantly distributed gears 8 and the clamping plate 6 to rotate around the inner wall of the rotating groove 5, so that the clamping block 7 at one end of the clamping plate 6 can achieve symmetrical multi-point clamping of the workpiece. Utilizing the self-locking characteristic of the worm gear 12 transmission, the relative position of the worm wheel 11 and the worm gear 12 is locked after the workpiece is clamped, preventing the clamping from loosening due to processing vibration. At the same time, the sliding cooperation between the guide groove 15 and the guide rod 16 provides precise motion guidance for the movement direction of the clamping block 7, avoiding clamping deviation.
