Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a special clamp device for grinding a machine clamp blade. Background Art

[0002] In the field of modern mechanical processing, efficient and precise processing is the key to improving production efficiency and product quality. With the continuous development of CNC machine tools and machining center technology, the requirements for cutting tools are getting higher and higher. Especially in precision machining and mass production, the performance of cutting tools directly affects the processing quality and cost control. As a common cutting tool, machine-clamped blades are frequently used in daily processing and production due to their good toughness and relatively low price. It is widely used in various processing methods such as turning and milling. Especially when facing complex workpieces or when blades need to be replaced frequently to adapt to different processing conditions, the advantages of machine-clamped blades are more obvious.

[0003] However, a notable feature of the machine-clamped blade is that it is easy to disassemble and can be repeatedly re-grinded, which makes it of great value in reducing tool costs. However, the traditional grinding method usually removes the blade from the cutter 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 dimensions after each grinding are completely consistent, resulting in the working surfaces of the two blades may not be on the same plane when they are re-installed on the cutter body for processing, which in turn affects the processing accuracy of the workpiece; second, separate grinding also increases the complexity and time cost of the operation. The existing grinding technology can only adjust the dimensions in the X / Y axis direction, while the adjustment in the Z axis direction cannot guarantee accuracy, especially the accuracy when the two blades are processed together. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a special clamp device for grinding machine-clamped blades, which solves the problem that it is difficult to ensure that the sizes of two blades after grinding are completely consistent each time when grinding two blades separately.

This not only improves the efficiency of blade sharpening, but also ensures the consistency of the blades after sharpening, thereby improving the accuracy and efficiency of subsequent workpiece processing.

[0016] The blade position depth in the Z-axis direction of the cutter body can be adjusted conveniently and quickly through the adjustment mechanism, and the position accuracy when adjusting the Z-axis direction is guaranteed through the cooperation of the guide assembly and the spindle.

[0025] like Figure 2 and Figure 3 As shown, the blade 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 blade body 1. In this embodiment, there are two blades 3 to achieve the purpose of synchronous grinding of the two blades.

[0026] During assembly, the two blades 3 are respectively mounted on the first assembly surface 2 and the second assembly surface 6 by the fixed pressure plate, and the blade edge of the blade 3 extends out of the first assembly surface 2 and the second assembly surface 6. The grinding length, angle and other dimensions of the two blades 3 at both ends of the X axis are adjusted by the fixed pressure plate and the gauge blocks of equal size. After tightening the fixed pressure plate (keeping a certain gap), the mechanism 7 is adjusted to adjust the depth of the blade in the Z axis direction.

[0027] like Figure 3As shown, the two adjustment mechanisms 7 are identical and each adjustment mechanism 7 is symmetrically arranged at a diagonal distance relative to each blade 3 in the blade body 1 to adjust the position depth of the blade 3 in the Z-axis direction of the blade body 1 .

[0028] like Figure 4 As shown, the adjustment mechanism 7 includes a driving part assembled on the blade body 1 and a platform 71 connected to the driving part. The driving part and the platform 71 are sequentially arranged in the cavity along the axial direction of the blade body 1. The platform 71 is moved forward and backward by the controlled adjustment of the driving part to adjust the position depth of the blade 3 in the Z-axis direction of the blade body 1 that contacts the platform 71. 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; wherein the driving part adjusts the position depth of the platform 71 and the blade 3 in the Z-axis direction of the blade body 1.

[0029] The driving part includes a driving member and a driven member. The driving member includes a rotating body, and an internal threaded sleeve 79 is arranged inside the rotating body; a main shaft 72 is arranged inside the internal threaded sleeve 79, and a threaded sleeve 711 is fixed to one end of the main shaft 72, and the threaded sleeve 711 is threadedly connected with the internal threaded sleeve 79. The rotating body is turned to rotate the internal threaded sleeve 79 together, and the threaded sleeve 711 and the internal threaded sleeve 79 are threadedly connected to each other, so that the threaded sleeve 711 and the main shaft 72 rotate in the positive and negative directions, and rise and fall in the internal threaded sleeve 79.

[0030] The rotating body includes a disk 712, on which an adjustment socket 710 is provided, and a scale is provided around the adjustment socket 719; the outer side of the disk 712 is rotatably connected to a base plate 713, which is fixed on the cutter body 1 and has a pointer on it.

[0031] The driven member includes an intermediate plate 75, a main shaft 72 is rotatably connected to one side of the intermediate plate 75, and a table 71 is fixed to the other side of the intermediate plate 75; the main shaft 72 drives the intermediate plate 71 to move up and down when it is lifted up and down, and a guide assembly is provided on the intermediate plate 75. The guide assembly ensures that the intermediate plate 75 and the table 71 can be stably driven by the main shaft 72 that moves up and down and follow the movement.

[0032] like Figure 4As shown, the guide assembly includes a first assembly plate 74 and a second assembly plate 76, the first assembly plate 74 is connected to the second assembly plate 76 through a connecting rod 73; the connecting rod 73 passes through 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 member. Among them, a first guide sleeve is provided on the second assembly plate 76, and the main shaft 72 that moves up and down is slidably connected in the first guide sleeve.

[0034] 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 arranged opposite to the adjusting mechanism 7 .

[0035] Working principle: First, install the blade 3 to be sharpened on the first assembly surface 2 and the second assembly surface 6 on both sides of the blade body 1, and pre-position it through the first fixed plate 4 and the second fixed plate 5. After pre-positioning, use conventional technical means (gauge blocks of equal size) to adjust the grinding length, angle and other dimensions of the two blades at both ends of the X axis. Use a tool to insert the rotating disc 712 into the adjustment socket, turn the rotating body to make the internal thread sleeve 79 rotate together, and through the threaded connection between the threaded sleeve 711 and the internal thread sleeve 79, the threaded sleeve 711 and the main shaft 72 rotate in the positive and negative directions, and rise and fall in the internal thread sleeve 79. When the main shaft 72 rises and falls, it drives the middle plate 71 and the table 71 to move up and down, adjusts the depth of the blade 3 in the Z axis direction, and then tightens the first fixed plate 4 and the second fixed plate 5.
