[0030] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0031] like Figures 1-5 As shown, a device for processing and forming a square shank of a tap includes a raw material 3, and also includes:

[0032] Base plate 1, on which a lifting unit 5 is installed;

[0033] Support frame 2 is mounted on base plate 1. A first motor 22 is mounted on support frame 2. A grinding wheel 21 is mounted on the output end of the first motor 22.

[0034] The clamping unit 4 is disposed on the lifting unit 5, and the clamping unit 4 includes a housing 41 and a cover plate 45 disposed on the housing 41. A first gear set 46 and a second gear set 47 that mesh with each other are disposed inside the housing 41.

[0035] The cover plate 45 is provided with a clamping member 44 that engages with the first gear set 46, and the raw material 3 is fixed to the first gear set 46 by the clamping member 44.

[0036] Specifically, the raw material 3 is cut from the tap raw material 3. The raw materials 3 are assembled one by one to the shaft of the spur gear 42 in the first gear set 46. The raw materials 3 are then fixed by the clamping member 44 to restrict the movement of the raw materials 3 in the axial direction. Then, the lifting unit 5 controls the raw materials 3 on the clamping unit 4 to contact the rotating grinding wheel 21 to complete the grinding of one side. The second gear set 47 controls the raw materials 3 on the first gear set 46 to rotate 90° in one direction to grind the second side of the raw materials 3. The above grinding operation is repeated four times, thereby completing the processing of the square shank of multiple tap raw materials 3 at one time, thereby improving the processing efficiency of the square shank of the tap.

[0037] As a further embodiment provided in this utility model, both the first gear set 46 and the second gear set 47 are composed of spur gears 42. The spur gears 42 in the first gear set 46 mesh sequentially with adjacent spur gears 42 in the second gear set 47. A second motor 451, cooperating with the second gear set 47, is provided on the cover plate 45. The first motor 22 and the second motor 451 are both model number RF-300, and the third motor 51 is model number MHMF042L1U4-1116. The second gear set 47 is controlled by the second motor 451. The first gear set 46 rotates, causing the spur gears 42 within it to rotate synchronously in one direction. The second motor 451 restricts the rotation of the material 3 on the first gear set 46 to prevent synchronous rotation during the grinding process. The first gear set 46 contains at least five spur gears 42, while the second gear set 47 contains one fewer spur gear 42 than the first gear set 46. This allows the spur gears 42 in the second gear set 47 to mesh sequentially with adjacent spur gears 42 in the first gear set 46 (e.g.,...). Figure 3 (As shown).

[0038] As a further embodiment provided by this utility model, each of the spur gears 42 in the first gear set 46 is fitted with a rubber sleeve 43. When the raw material 3 initially enters the spur gear 42, it will contact the rubber sleeve 43 in advance to restrict the movement of the raw material 3 and improve the installation accuracy of the raw material 3 on the first gear set 46.

[0039] As a further embodiment of this utility model, the clamping member 44 includes a turntable 445 and a sleeve 444 snapped onto the turntable 445. The sleeve 444 is provided with a circumferential array of fitting pieces 443 that abut against the raw material 3. The turntable 445 is threadedly connected to a rotating cover 441. The rotating cover 441 is provided with a conical surface 442 that cooperates with the fitting pieces 443. The clamping member 44 is used to fix the raw material 3 onto the spur gear 42 on the first gear set 46 to prevent the raw material 3 from moving along the axial direction of the spur gear 42. When the raw material 3 is placed at the axial center of the spur gear 42, the rotating cover 441 can be rotated to move the fitting pieces 443 toward the axial center of the spur gear 42 through the conical surface 442, so that the fitting pieces 443 gradually increase the squeezing force against the raw material 3 until the raw material 3 is fixed onto the spur gear 42. The first gear set 46 is a plurality of gears that can assemble and process multiple tap raw materials 3 at one time, thereby improving the processing efficiency of the tap raw materials 3.

[0040] As a further embodiment provided in this utility model, a slot 446 is provided on the turntable 445. The slot 446 on the turntable 445 engages with the spur gear 42 of the first gear set 46. During the rotation of the spur gear 42 of the first gear set 46, the clamping member 44 will rotate synchronously.

[0041] As a further embodiment of this utility model, a slide 23 is slidably arranged on the support frame 2. The first motor 22 and the grinding wheel 21 are both arranged on the slide 23. A screw 24 that engages with the slide 23 is provided on the support frame 2. Rotating the screw 24 can control the slide 23 to slide back and forth on the support frame 2, thereby adjusting the distance between the grinding wheel 21 and the raw material 3, so as to grind the end of the raw material 3 step by step, thereby gradually changing the end of the raw material 3 into a square shape.

[0042] As a further embodiment of this utility model, the lifting unit 5 includes a column 53, a third motor 51, and a lead screw 54 disposed at the output end of the third motor 51. A slider 55 supporting the clamping unit 4 is disposed on the lead screw 54. The lead screw 54 is rotatably disposed on the column 53. Bearings are disposed at both ends of the lead screw 54 to improve the rotation effect of the lead screw 54 on the column 53. The lead screw 54 is the sliding distance of the slider 55 to improve the sliding effect of the slider 55.

[0043] As a further embodiment of this utility model, a slide rail 52 is provided on the column 53, and the slider 55 slides on the slide rail 52. The slide rail 52 improves the sliding stability of the slider 55, thereby improving the contact stability between the raw material 3 and the grinding wheel 21 on the clamping unit 4.

[0044] As a further embodiment of this utility model, a distance sensor 56 is provided on the column 53. The distance sensor 56 is used to detect the limit of the moving area of ​​the slider 55. When the slider 55 moves to the end of the column 53, the distance sensor 56 detects this and controls the third motor 51 to reverse so that the slider 55 slides upward along the lead screw 54.

[0045] As a further embodiment of this utility model, a material trough 11 is provided on the base plate 1, and a waste frame can be provided on the material trough 11 to collect the debris generated during the grinding process, thereby improving the cleaning efficiency after processing.

[0046] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
