With the continuous development of numerical control machine tools and machining center technology, the requirements for cutting tools are also increasing, especially in precision machining and batch production, the performance of the cutting tool directly affects the processing quality and cost control. Machine clamped blades, as a common cutting tool, are widely used in turning, milling and other processing methods, especially when facing complex workpieces or needing to frequently replace blades to adapt to different processing conditions, the advantages of machine clamped blades are more obvious.

[0003] However, one of the notable features of machine clamped blades is that they are easy to disassemble and can be repeatedly used after multiple grinding. This feature makes it important in reducing tool costs. However, the traditional grinding method usually disassembles the blade from the tool body and grinds it separately. This method has several obvious shortcomings: first, since the two blades are ground separately, it is difficult to ensure that the size after each grinding is exactly the same, which may cause the working surfaces of the two blades to not be in the same plane when reinstalled on the tool body for processing, thereby affecting the processing accuracy of the workpiece; second, separate grinding also increases the complexity and time cost of operation, and existing grinding technology can only adjust the X / Y axis direction size, but the Z axis direction adjustment cannot guarantee accuracy, especially when two blades are processed together. SUMMARY

As long as the effects of the present invention can be exerted, various changes can be made to the embodiments.

[0035] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.

[0036] Reference Figures 1-5 A special clamping device for grinding a machine-clamped blade according to this embodiment is described.

[0037] like Figure 1 As shown, the device includes a cutter body 1 and a blade 3, and an adjustment mechanism 7 for adjusting the depth of the blade 3 in the Z-axis direction of the cutter body 1. A cavity for accommodating the adjustment mechanism 7 is formed in the cutter body 1, and the cavity is arranged along the axis direction of the cutter body 1.

[0038] like Figure 2 and Figure 3 As shown, the cutter body 1 has a first assembly surface 2 and a second assembly surface 6, which are symmetrically arranged at diagonal distances on opposite sides of the cutter body 1. In this embodiment, there are two blades 3 to achieve the purpose of synchronous grinding of the two blades.

[0039] During assembly, the two blades 3 are mounted on the first and second mounting surfaces 2 and 6, respectively, using fixed pressure plates. The cutting edges of the blades 3 extend beyond the first and second mounting surfaces 2 and 6. The fixed pressure plates and gauge blocks of equal size are used to adjust the grinding length, angle, and other dimensions of the two blades 3 at both ends of the X-axis. After tightening the fixed pressure plates (leaving a certain gap), the adjustment mechanism 7 is then used to adjust the blade's depth in the Z-axis direction.

[0040] like Figure 3As shown, the two adjustment mechanisms 7 are identical and each adjustment mechanism 7 is symmetrically arranged diagonally relative to each blade 3 in the cutter body 1 to adjust the position depth of the blade 3 in the Z-axis direction of the cutter body 1 .

[0041] like Figure 4 As shown, the adjustment mechanism 7 includes a drive unit mounted on the blade body 1 and a platform 71 connected to the drive unit. The drive unit and the platform 71 are sequentially arranged in the cavity along the axis of the blade body 1. The platform 71 is moved forward and backward by the control of the drive unit to adjust the position and depth of the blade 3 in contact with the platform 71 in the Z-axis direction of the blade body 1. The platform 71 is located at the first assembly surface 2 and the second assembly surface 6 and contacts the wall surface of the blade 3; the drive unit adjusts the position and depth of the platform 71 and the blade 3 in the Z-axis direction of the blade body 1.

[0042] The drive unit includes a driver and a driven member. The driver includes a rotating body with an internally threaded sleeve 79 disposed inside the rotating body. The spindle 72 is disposed within the internally threaded sleeve 79. A threaded sleeve 711 is fixed to one end of the spindle 72, which is threadedly connected to the internally threaded sleeve 79. Turning the rotating body causes the internally threaded sleeve 79 to rotate together. Through the threaded connection between the threaded sleeve 711 and the internally threaded sleeve 79, the threaded sleeve 711 and the spindle 72 rotate in forward and reverse directions, and rise and fall within the internally threaded sleeve 79.

[0043] The rotating body includes a disc 712, which is provided with an adjustment socket 710 and a scale around the adjustment socket 719; the outer side of the disc 712 is rotatably connected to a base disc 713, which is fixed on the cutter body 1 and has a pointer on it.

[0044] The driven member includes an intermediate plate 75, with a spindle 72 rotatably connected to one side of the intermediate plate 75 and a table 71 fixed to the other side. The spindle 72 drives the intermediate plate 71 up and down during the vertical movement. A guide assembly is provided on the intermediate plate 75. This guide assembly ensures that the intermediate plate 75 and the table 71 can stably follow the movement of the spindle 72 as it moves up and down.

[0045] like Figure 4The guide assembly includes a first assembly plate 74 and a second assembly plate 76, the first assembly plate 74 is connected with the second assembly plate 76 through a connecting rod 73, the connecting rod 73 penetrates the middle plate 75, the cavity has a first step surface 8 and a second step surface 9, and the first assembly plate 74 and the second assembly plate 76 are fixed on the first step surface 8 and the second step surface 9 by a limiting piece. The second assembly plate 76 is provided with a first guide sleeve, and the main shaft 72 moving up and down is slidably connected in the first guide sleeve. The first assembly plate 74 is provided with a second guide sleeve, the table piece 71 is fixed on the middle plate 75 after penetrating the first assembly plate 74, and the tail end of the table piece 71 is slidably connected in the second guide sleeve, and the first guide sleeve, the second guide sleeve and the connecting rod 73 are on the same axis. The first guide sleeve, the second guide sleeve and the connecting rod 73 assist the table piece 71 to move in the Z-axis direction, so as to adjust the position depth of the table piece 71 and the blade 3 in the Z-axis direction of the cutter body 1.

[0046] The limiting piece includes a gland 78 and a pressing ring 77. The gland 78 is fixed on the cutter body 71, and the pressing ring 77 abuts between the second assembly plate 76 and the gland 78. The limiting piece press-fixes the guide assembly, guarantees the stability in the guiding process, and improves the guiding precision.

[0047] The fixed pressing plate includes a first fixed pressing plate 4 and a second fixed pressing plate 5, and the second fixed pressing plate 5 is oppositely arranged with the adjusting mechanism 7.

[0048] Working principle: firstly, the blade 3 to be ground is installed on the first assembly surface 2 and the second assembly surface 6 on both sides of the cutter body 1, and is pre-positioned through the first fixed pressing plate 4 and the second fixed pressing plate 5. After the pre-positioning, the grinding length, angle and other sizes of the two blades at the two ends of the X-axis are adjusted by using conventional technical means (equal size blocks). The tool is inserted into the adjusting hole and the rotating disc 712 is rotated, the rotating body is rotated to drive the internal thread sleeve 79 to rotate, the threaded sleeve 711 is connected with the internal thread sleeve 79 through the thread connection, the threaded sleeve 711 and the main shaft 72 rotate in the positive and negative directions, and the internal thread sleeve 79 is raised and lowered. The main shaft 72 drives the middle plate 71 and the table piece 71 to move up and down when it is raised and lowered, adjusts the depth of the Z-axis direction of the blade 3, and then fastens the first fixed pressing plate 4 and the second fixed pressing plate 5. After the X-axis and the Z-axis are fixed, the tool setting instrument is used to adjust the tool swing and the size and angle of the blade, and then the synchronous grinding of the two blades can be carried out.
