Description

Technical Field

[0001] This utility model relates to the field of stator core processing technology, and more specifically, it relates to a tapping device for stator core processing. Background Technology

[0002] Tapping is the process of creating internal threads in a pre-drilled hole using a tap (a cutting tool). It is widely used in various industries to create threaded holes for installing fasteners such as bolts and screws.

[0003] The main tool for tapping is the tap. Taps can be divided into many types according to their shape and purpose, such as hand taps, machine taps, flat-head taps, and pointed taps.

[0004] However, when using a pointed tap to tap shallow holes, the tip of the tap contacts the hole, but the body of the tap does not. This results in only the tip of the tap contacting the hole, which can lead to misalignment between the center of the pointed tap and the center of the hole being tapped. As the pointed tap rotates, it may become misaligned with the hole, causing damage to the hole or bending of the thread, resulting in damage or even rendering the part unusable.

[0005] Therefore, a tapping device for stator core machining is proposed to improve the existing problems. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a tapping device for stator core processing.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tapping device for stator core processing, comprising a base, a lifting mechanism on the top of the base, a tapping motor on one side of the lifting mechanism, a tapping cylinder at the output end of the tapping motor, and a tap at the bottom of the tapping cylinder; a retaining ring on the outer wall of the tapping cylinder, electric telescopic rods evenly arranged at the bottom of the retaining ring, a bottom ring between the electric telescopic rods, and cylinders evenly arranged at the top of the bottom ring, with connecting rods at the telescopic end of the cylinders.

[0008] The present invention is further configured such that: rollers are provided around the base; the lifting mechanism includes a column, a support shell provided on one side of the column, a motor provided on the top of the support shell, a threaded rod provided at the output end of the motor, a nut block sleeved on the threaded rod, and a clamping plate provided on one side of the nut block; the support shell has a U-shaped structure, the output end of the motor passes through the top of the support shell and is connected to the threaded rod, and the end of the threaded rod away from the output end of the motor is rotatably connected to the bottom of the inner wall of the support shell.

[0009] The present invention is further configured such that: sliding rods are radially symmetrically distributed on both sides of the threaded rod, and a collar is sleeved on the outer wall of the sliding rod, with one side of the collar connected to the clamping plate.

[0010] The present invention is further configured such that: the output end of the tapping motor passes through the top of the clamping plate and is connected to the tapping cylinder; the bottom of the tapping cylinder is provided with a tapping groove, and the tapping groove is connected to the tap by a thread.

[0011] The present invention is further configured such that the output ends of the three electric telescopic rods are all connected to the top of the bottom ring.

[0012] The present invention is further configured such that: the inner diameter of the bottom ring is greater than the diameter of the tap cross-section, and the center of the bottom ring is perpendicularly aligned with the center of the tap.

[0013] The present invention is further configured such that: the cylinder is horizontally distributed on the top of the bottom ring, and the connecting rod is perpendicular to the output end of the cylinder.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] The cylinder is activated by extending and retracting its end, which drives the connecting rods to approach the inner wall of the bottom hole. When all three connecting rods are in contact with the inner wall of the bottom hole, the cylinder stops extending and retracting. At this point, the center of the tap coincides with the center of the bottom hole, thus achieving precise positioning. This avoids the problem of the center of the pointed tap being out of axis with the center of the bottom hole to be tapped, and improves the production quality of internal threads.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0026] Please see Figures 1-7 The present invention provides the following technical solution:

[0027] Example 1, see Figures 1-7 A tapping device for stator core processing includes a base 1, a lifting mechanism 2 is provided on the top of the base 1, a tapping motor 3 is provided on one side of the lifting mechanism 2, a tapping cylinder 4 is provided at the output end of the tapping motor 3, and a tap 5 is provided at the bottom of the tapping cylinder 4.

[0028] A retaining ring 6 is provided on the outer wall of the tapping cylinder 4. Electric telescopic rods 7 are evenly arranged at the bottom of the retaining ring 6. A bottom ring 8 is arranged between the electric telescopic rods 7. A cylinder 9 is evenly arranged at the top of the bottom ring 8. A connecting rod 10 is provided at the telescopic end of the cylinder 9.

[0029] In the initial state, the output end of the electric telescopic rod 7 is in a retracted state, the bottom ring 8 driven by the electric telescopic rod 7 is located above the working part of the tap 5, the telescopic end of the cylinder 9 is also in a retracted state, and the connecting rod 10 driven by the cylinder 9 is close to the inner wall of the bottom ring 8.

[0030] When the tapping device starts tapping, the lifting mechanism 2 is activated, driving the tap 5 to move downwards. At the same time, the electric telescopic rod 7 drives the bottom ring 8 to move downwards as well. It should be noted that the moving speed of the output end of the electric telescopic rod 7 is greater than the descending speed of the lifting mechanism 2. Therefore, when the tap 5 descends to near the bottom hole to be tapped, the bottom ring 8 driven by the electric telescopic rod 7 is already below the working part of the tap 5. At this time, the telescopic end of the cylinder 9 also begins to extend. It should be noted that the extension speed of the telescopic end of the cylinder 9 is greater than the descending speed of the lifting mechanism 2. Therefore, when the bottom of the bottom ring 8 contacts the surface of the bottom hole to be tapped, the three connecting rods 10 driven by the telescopic ends of the three cylinders 9 have approached each other and entered the interior of the bottom hole to be tapped.

[0031] At this time, the telescopic end of cylinder 9 begins to retract, and the connecting rod 10 driven by the telescopic end of cylinder 9 also begins to approach the inner wall of the bottom hole. When all three connecting rods 10 are in contact with the inner wall of the bottom hole, the telescopic end of cylinder 9 stops. At this time, the center of tap 5 coincides with the center of the bottom hole, thus achieving the purpose of precise positioning, avoiding the problem that the center of the pointed tap and the center of the bottom hole to be tapped are not on the same axis, and improving the production quality of internal threads.

[0032] Then, the electric telescopic rod 7 begins to retract, and the electric telescopic rod 7 drives the bottom ring 8 back to the top of the working part of the tap 5. At the same time, the telescopic end of the cylinder 9 also begins to retract, and the cylinder 9 drives the connecting rod 10 back to a position close to the inner wall of the bottom ring 8. At this time, neither the bottom ring 8 nor the connecting rod 10 will affect the tap 5 from tapping. At this time, the tapping motor 3 starts, driving the tap 5 to rotate. Then, the lifting mechanism 2 restarts, driving the tap 5 to move downward and enter the bottom hole for tapping, thus achieving the purpose of tapping.

[0033] See Figures 1-7 Furthermore, casters 11 are provided around the base 1.

[0034] The lifting mechanism 2 includes a column 21, a support shell 22 disposed on one side of the column 21, a motor 23 disposed on the top of the support shell 22, a threaded rod 24 disposed on the output end of the motor 23, a nut block 25 sleeved on the threaded rod 24, and a clamping plate 26 disposed on one side of the nut block 25; the support shell 22 has a U-shaped structure, the output end of the motor 23 passes through the top of the support shell 22 and is connected to the threaded rod 24, and the end of the threaded rod 24 away from the output end of the motor 23 is rotatably connected to the bottom of the inner wall of the support shell 22.

[0035] When motor 23 starts, its output end rotates. Since threaded rod 24 is connected to the output end of motor 23, threaded rod 24 also rotates. Since nut block 25 is fitted on threaded rod 24, nut block 25 moves up and down as it rotates, thereby driving clamping plate 26 to move up and down, thus realizing the up and down movement of lifting mechanism 2.

[0036] See Figures 1-7 Furthermore, the threaded rod 24 has radially symmetrically distributed sliding rods 12 on both sides, and a collar 13 is sleeved on the outer wall of the sliding rod 12. One side of the collar 13 is connected to the clamping plate 26.

[0037] The collar 13 is fitted onto the slide bar 12, which not only does not affect the normal lifting and lowering of the clamping plate 26, but also provides a more stable guide for the clamping plate 26, thereby significantly improving the smoothness and efficiency of the lifting and lowering process.

[0038] See Figures 1-7 Furthermore, the output end of the tapping motor 3 passes through the top of the clamping plate 26 and is connected to the tapping cylinder 4. The bottom of the tapping cylinder 4 is provided with a tapping groove 41, which is connected to the tap 5 by a thread.

[0039] The tapping groove 41 is connected to the tap 5 by a thread, which facilitates the subsequent replacement of other types of taps 5 and improves the flexibility and versatility of tapping.

[0040] See Figures 1-7 Furthermore, the output ends of the three electric telescopic rods 7 are all connected to the top of the bottom ring 8.

[0041] The output end of the electric telescopic rod 7 is connected to the top of the bottom ring 8, thereby controlling the lifting and lowering of the bottom ring 8 and providing great convenience for tapping positioning.

[0042] See Figures 1-7 Furthermore, the inner diameter of the bottom ring 8 is larger than the diameter of the cross-section of the tap 5, and the center of the bottom ring 8 is perpendicularly aligned with the center of the tap 5.

[0043] The inner diameter of the bottom ring 8 is larger than the diameter of the tap 5 cross section, which ensures that the bottom ring 8 will not contact the tap 5 under the drive of the electric telescopic rod 7, thus avoiding the bottom ring 8 from affecting the normal tapping of the tap 5.

[0044] See Figures 1-7 Furthermore, cylinder 9 is horizontally distributed on the top of bottom ring 8, and connecting rod 10 is perpendicular to the output end of cylinder 9.

[0045] Because of the horizontal distribution of cylinder 9 and the perpendicularity of connecting rod 10 to cylinder 9, connecting rod 10 is perpendicular to bottom ring 8 and parallel to tap 5.

[0046] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
