Furthermore, the support is also provided with a clamping structure for preventing the horizontal adjustment mechanism and / or the vertical adjustment mechanism from being displaced, so that the horizontal adjustment mechanism and the vertical adjustment mechanism are prevented from being displaced during the spinning process of the profiling plate 1 after adjustment. In addition, the vertical adjustment mechanism is provided with an angle adjustment assembly 13, which is used for fine adjustment of the angle of the profiling plate 1 when the upper dimension of the profiling plate 1 is qualified and the lower dimension is unqualified.

[0035] Further, as shown in Figure 2 and Figure 3 The vertical adjustment mechanism comprises a vertical support 2, a vertical screw rod 3 rotatably connected with the vertical support 2, a vertical screw rod nut 4 engaged with the vertical screw rod 3, and a vertical sliding plate 5 fixedly connected with the vertical screw rod nut 4. The vertical support 2 is connected with the horizontal adjustment mechanism. The vertical sliding plate 5 can move up and down on the vertical support 2, and the profiling plate 1 is connected with the vertical sliding plate 5. A vertical sliding rail 21 and a vertical sliding block matched with each other are arranged between the vertical support 2 and the vertical sliding plate 5. In this embodiment, the cross section of the vertical support 2 is in the shape of “∏”, so that the vertical support 2 is in the shape of “∏” from the vertical direction. The upper and lower ends of the vertical support 2 are provided with bearing seats, so that the upper and lower ends of the vertical screw rod 3 are rotatably connected with the bearing seats. The vertical screw rod nut 4 is engaged with the middle part of the vertical screw rod 3. The outer sides of the left and right sides of the “∏” structure are respectively provided with the vertical sliding rail 21. The left and right sides of the vertical sliding plate 5 are connected with the vertical sliding blocks matched with the vertical sliding rail 21. In another preferred embodiment, the cross section of the vertical sliding plate 5 is in the shape of “U”, so that the vertical sliding plate 5 is in the shape of “U” from the vertical direction. The “∏” structure is located in the “U” structure, so that the two sides of the “U” structure are located on the outer sides of the two sides of the “∏” structure. The vertical sliding blocks are fixed on the inner walls of the two sides of the “U” structure. The vertical screw rod 3 is connected with a vertical hand wheel 8 at the upper end. The vertical hand wheel 8 is used for rotating the vertical screw rod 3.

[0036] Embodiment 2 is different from embodiment 1 in thatFigure 1 and Figure 2 As shown, the vertical support 2 is equipped with a vertical digital scale 14, and the length direction of the vertical digital scale 14 is parallel to the sliding direction of the vertical sliding plate 5 relative to the vertical support 2. That is, the length direction of the vertical digital scale 14 extends along the vertical direction, and the vernier of the vertical digital scale 14 is connected to the vertical sliding plate 5. This allows the vernier to move when the vertical sliding plate 5 moves, making it easier to accurately observe the displacement.

[0037] Example 3 differs from Example 1 in that, as Figure 1 and Figure 4 As shown, the contour plate 1 has a pin hole 101 at the top and an arc groove at the bottom. The vertical sliding plate 5 has an upper pin and a lower pin that pass through the pin hole 101 and the arc groove, respectively. The upper pin is rotatably engaged with the pin hole 101, and the lower pin is slidably engaged with the arc groove, allowing the contour plate 1 to rotate around the upper pin to adjust its angle. The part of the upper pin that engages with the contour plate 1 is a smooth shaft, and the outer end of the upper pin has an external thread and is threaded to a nut. Tightening the nut presses the upper part of the contour plate 1 firmly against the vertical sliding plate 5. The lower pin is a bolt threaded to the vertical sliding plate 5. Tightening the bolt presses the lower part of the contour plate 1 firmly against the vertical sliding plate 5, preventing the angle of the contour plate 1 from shifting and thus fixing its position. Loosening the nut and bolt facilitates adjustment of the angle of the contour plate 1.

[0038] In this embodiment, as Figure 4 As shown, the lower part of the contour plate 1 has two arc-shaped grooves: arc-shaped groove 103 at the bottom and arc-shaped groove 102 between arc-shaped groove 103 and pin hole 101. Correspondingly, the vertical sliding plate 5 has three pins: an upper pin that engages with pin hole 101, and two lower pins that engage with arc-shaped groove 103 and arc-shaped groove 102. Figure 5 As shown, the vertical sliding plate 5 has three through holes at its upper, middle, and lower positions for three pins to pass through, namely hole E, hole F, and hole G. That is, pins are respectively inserted through holes E, F, and G, and these three pins pass through pin hole 101, arc groove one 102, and arc groove two 103 to connect to the contour plate 1. Figure 4 As shown, the side of the contour plate 1 has three locations, B, C, and D, corresponding to holes E, F, and G, respectively.

[0039] In a preferred embodiment, the pin hole 101 on the template 1 corresponding to the hole E is a high-precision pin hole to facilitate positioning and reduce the fixing gap of the template. The end of the upper pin shaft passing through the pin hole 101 and the hole E is threaded, and the middle part of the upper pin shaft that mates with the pin hole 101 is a section of smooth round shaft, which is used to position and mate with the pin hole 101 of the template.

Since the vertical adjustment mechanism itself has a self-weight, and in the process of spinning, it is spun downward to generate a downward force, in order to avoid the downward movement of the vertical sliding plate 5 and the profiling plate thereon, a jacking structure is arranged to prevent the downward movement of the vertical sliding plate 5. The jacking structure includes a vertical jacking piece 20 arranged on the base 19 for jacking the vertical sliding plate 5 upward. In this embodiment, the jacking piece 20 is a bolt screwed on the base 19, and the upper end of the bolt is aligned with the lower side of the vertical sliding plate 5. A nut is arranged on the bolt. After the profiling plate 1 is adjusted in place, the upper end of the bolt jacks the lower side of the vertical sliding plate 5, and the bolt is locked by the nut, effectively locking the position of the vertical sliding plate 5, thereby preventing the downward movement of the profiling plate.

[0041] Example 5, which differs from example 3 in that, as shown in Figure 1 and Figure 2 The angle adjustment assembly 13 is arranged on one side of the profiling plate 1. The angle adjustment assembly 13 includes a fixed block 131 fixedly connected on the vertical sliding plate 5 and close to one side of the profiling plate 1, and an adjustment screw 132 threaded through the fixed block 131, and the adjustment screw 132 is threadedly connected with the fixed block 131. The front end of the adjustment screw 132 is aligned with the profiling plate 1 and abuts against the lower side of the profiling plate 1. After the nuts on the three pin shafts of the E hole, F hole and G hole are loosened, the adjustment screw 132 is turned to push the profiling plate 1 to rotate around the upper pin shaft of the E hole, thereby adjusting the angle of the profiling plate 1. Moreover, a nut is arranged on the adjustment screw, and after adjustment, the adjustment screw jacks the profiling plate 1 and locks the nut, which can effectively prevent the profiling plate from retreating.

[0042] Further, as shown in Figure 2 and Figure 4 The lower end of the profiling plate 1 is provided with an angle indicating arrow 104, and the vertical sliding plate 5 is provided with an angle scale line matched with the angle indicating arrow 104, as shown in Figure 5 which facilitates accurate angle adjustment.

The support and the vertical support 2 are provided with a matching lateral sliding rail 9 and a lateral sliding block 22.

[0044] In this embodiment, as shown in Figure 6 , the upper and lower sides of the support 18 are provided with thickened parts protruding towards the vertical support 2, the thickened parts are fixed with the lateral sliding rail 9, and the lateral sliding block 22 is fixed at the corresponding positions of the upper and lower parts of the back of the vertical support 2. In addition, one end of the lateral screw rod 6 is connected with a lateral hand wheel 12, which facilitates the rotation of the lateral screw rod 6. By rotating the lateral screw rod 6, the lateral screw rod nut 7 drives the vertical adjusting mechanism and the profiling plate 1 on it to move left and right to adjust the position through the vertical support 2.

[0045] Embodiment 7, which is different from embodiment 6, as shown in Figure 3 , the lateral sliding rail 9 is provided with a dovetail, and the lateral sliding block 22 is provided with a dovetail groove slidingly matched with the dovetail. The dovetail groove and the dovetail slidingly matched make the vertical adjusting mechanism move stably in the lateral direction. A gap is left between the upper side of the dovetail and the dovetail groove, and an adjusting piece 10 is arranged in the gap, and an adjusting screw 11 is arranged in the upper side wall of the dovetail groove, the lower end of the adjusting screw 11 is used to tightly press the adjusting piece 10, so as to avoid the displacement of the profiling plate when the gap of the dovetail groove is too large, and the gap is reduced by the adjusting screw to ensure the stability of the profiling plate.

[0046] Embodiment 8, which is different from embodiment 6, as shown in Figure 1 and Figure 4 , the support 18 of the support is provided with a lateral digital scale 15, and the length direction of the lateral digital scale 15 is parallel to the sliding direction of the vertical support 2 relative to the support, that is, the length direction of the lateral digital scale 15 extends along the horizontal direction. The vernier of the lateral digital scale 15 is connected with the vertical support 2, so that when the vertical adjusting mechanism moves laterally as a whole, the vernier moves, which is convenient for accurately observing the displacement.

[0047] Embodiment 9, which is different from embodiment 6, as shown in Figure 1 and Figure 4As shown, the support 18 of the bracket is provided with a limiting plate 16 for limiting the transverse displacement of the vertical support 2 near the ends of the transverse screw rod 6. The tightening structure further comprises a limiting pull rod 17 provided on the limiting plate 16, the limiting pull rod 17 is threadedly connected with the limiting plate 16, and the end of the limiting pull rod 17 is aligned with the side surface of the vertical support 2. The limiting pull rod 17 is provided with a nut. After the profiling plate 1 is adjusted in place, the limiting pull rod 17 tightens the side surface of the vertical support 2, and the limiting pull rod is locked through the nut, thereby effectively locking the position of the vertical support 2. In the embodiment, at least one set of limiting plate 16 and limiting pull rod 17 is arranged at the upper and lower positions on both sides of the support 18.

[0048] The profiling plate adjustable fixing device of the utility model can solve the problem that the existing profiling plate cannot be rotated, and when the diameter at B is qualified but the diameters at C and D are not qualified, the profiling plate can only be disassembled, then the size of the profiling plate is adjusted in the numerical control machining center, and the size of the local profiling plate is adjusted to realize size adjustment, thereby the problems of low efficiency and slow speed are solved.

[0049] During the adjustment, if the diameters at C and D are qualified but the diameter at B is not qualified, the profiling plate is adjusted to move transversely through the transverse hand wheel 12 until the diameter at B is qualified, and then the diameters at C and D can be qualified according to the rotation of the profiling plate (in short, during the adjustment, the diameter at B is adjusted first). Generally, the angle of rotation of the profiling plate is very small, and will not exceed 2°.
