DETAILED DESCRIPTION

[0013] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0014] like Figure 1 As shown, a special angle tooling for grinding tooth plates includes a permanent magnetic suction cup 1, on which are provided two first touch plates 2 and second touch plates 3 arranged perpendicular to each other, and an "L"-shaped support plate 4, which includes a bottom edge 401 and a vertical edge 402 arranged perpendicular to each other, a first arc-shaped protrusion 5 is provided on one side of the bottom edge 401, and a second arc-shaped protrusion 6 and a third protrusion 7 are provided on one side of the vertical edge 402, the first protrusion 5, the second protrusion 6 and the third protrusion 7 are all equal in size, and an angle adjustment part 8 is also included, which is located between the second protrusion 6 and the second touch plate 3, and the angle adjustment part 8 includes a plurality of pads, and the angle between the vertical edge 402 and the second touch plate 3 is controlled by controlling the thickness of the angle adjustment part 8.

[0015] The permanent magnetic chuck 1 is fixed on the grinding machine. After the permanent magnetic chuck 1 is powered on, the support plate 4, the thread rolling plate 9 and the angle adjustment part 8 can all be adsorbed on the permanent magnetic chuck 1 by magnetic attraction.

[0016] Before grinding the rubbing plate 9, first calculate the thickness H of the angle adjustment part 8 according to the lead angle of the rubbing plate 9. The thickness H of the angle adjustment part 8 is calculated as follows: first measure the shortest distance L between the centers of the second protrusion 6 and the third protrusion 7. It is assumed here that the distance L is 300 mm, and the lead angle R of the rubbing plate 9 is known. Assuming that the lead angle of the rubbing plate 9 is 3.4°, the thickness formula of the angle adjustment part 8 is H=L*SIN(R). Substituting the above data into H=17.19 mm, rounding to two decimal places means that the thickness of the angle adjustment part 8 is 17.19 mm. Since the angle adjustment part 8 is composed of multiple pads, and the thickness of each pad is known and specific, for example, the pads have various specifications such as 1.00 mm, 1.01 mm, 1.02 mm, 1.10 mm, 1.11 mm, 2.00 mm, and 5.00 mm. The maximum thickness of the pad should not exceed 10.00mm. By selecting pads of appropriate number and thickness, the total thickness of all selected pads can be equal to 17.19mm. For example, five pads of 10.00mm, 4.00mm, 1.15mm, 1.02mm and 1.02mm can be selected. Then the above five pads are placed between the second protrusion 6 and the second support plate 4, and the third protrusion 7 is in contact with the second touch plate 3, and the first protrusion 5 is in contact with the first touch plate 2. At this time, the position of the support plate 4 on the permanent magnetic suction cup 1 is determined, and then the rubbing plate 9 is placed on the permanent magnetic suction cup 1, and the two side edges connected to the rubbing plate 9 are in contact with the first touch plate 2 and the second touch plate 3 respectively to complete the positioning of the rubbing plate 9. Then the permanent magnetic suction cup 1 is started, and the support plate 4, the rubbing plate 9 and the pads are adsorbed and fixed on the permanent magnetic suction cup 1 by the generated magnetic force, so as to facilitate the subsequent grinding of the rubbing plate 9 by the grinding wheel.

[0017] The processing accuracy error of the above-mentioned rubbing plate 9 is within ten threads, which meets the processing requirements of the product.

[0018] Furthermore, a fourth arc-shaped protrusion 10 is provided on one side of the vertical edge 402 and located in the middle of the second protrusion 6 and the third protrusion 7. The size of the fourth protrusion 10 is equal to that of the second protrusion 6. The shortest distance between the centers of the fourth protrusion 10 and the third protrusion 7 is half of the shortest distance between the centers of the second protrusion 6 and the third protrusion 7. When the angle adjustment portion 8 is placed between the fourth protrusion 10 and the second touch plate 3, the thickness of the angle adjustment portion 8 is h. When the angle adjustment portion 8 is placed between the second protrusion 6 and the second touch plate 3, the thickness of the angle adjustment portion 8 is H, then H=2h, that is, when the angle adjustment portion 8 is placed between the fourth protrusion 10 and the second touch plate 3, the number of required pads can be reduced accordingly, thereby avoiding the need to remove too many pads.

[0019] Furthermore, the height of the angle adjustment portion 8 when placed on the permanent magnetic chuck 1 is not higher than the height of the backing plate 4 placed on the permanent magnetic chuck 1, thereby preventing the grinding wheel from touching the pad during the grinding of the thread-grinding plate 9.

[0020] Furthermore, the pads are magnetic, and different pads can attract each other through magnetism, which makes it easy to connect multiple pads together and then place them together on the permanent magnetic suction cup 1, thereby improving the ease of use of the pads.

[0021] Furthermore, an arcuate groove 11 is provided at the position where the bottom edge 401 of the support plate 4 is connected to the vertical edge 402, which can prevent the support plate 4 from contacting the edges of the rubbing plate 9 and facilitate alignment of the rubbing plate 9 with the support plate 4.

[0022] When the device is in use, the thickness of the angle adjustment part 8 can be calculated by the lead angle of the rubbing plate 9, and then pads of appropriate number and thickness can be placed on the permanent magnetic suction cup 1 to facilitate adjustment of the angle of the back plate 4 on the permanent magnetic suction cup 1, and also facilitate placement of the rubbing plate 9 on the inner side of the back plate 4, thereby improving the placement efficiency and accuracy of the rubbing plate 9 and achieving good use effect.

[0023] In the description of this utility model, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
