Description

Technical Field

[0001] The invention belongs to the technical field of lathe processing, and in particular relates to an adjustable tool bracket used for grinding tools on a numerically controlled grinder. Background Art

[0002] Over time, the surface of machining cutting tools will inevitably wear out. Regrinding can restore the sharpness and geometry of the tool, thereby extending its service life and reducing the frequency and cost of tool replacement. This process is crucial to maintaining machining efficiency, improving product quality, reducing production costs and extending equipment life.

[0003] Traditional grinding methods mostly rely on the personal experience of operators, which not only leads to instability and poor repeatability of grinding quality, but also may cause errors in the grinding process due to the lack of precise positioning and adjustment mechanisms, thus affecting the service life and processing accuracy of the tool. In addition, manual grinding is inefficient and cannot meet the strict requirements of modern manufacturing for high efficiency and high precision.

[0004] However, when using a CNC grinder to grind tools, due to the large length of some tools, after the basic clamping is completed on the machine tool, the overhang length of the part to be ground is large (far away from the clamping point), and then the tool vibration occurs during grinding due to its own insufficient rigidity, affecting the grinding stability and tool grinding accuracy. Therefore, it is particularly important to develop an adjustable tool holder that can improve the stability of CNC grinder tool grinding. Summary of the invention

[0041] An embodiment of the present invention provides an adjustable tool holder for grinding tools on a CNC grinder. Through multi-dimensional adjustment of the position of a tool support block, effective support of the tool by the tool holder is ensured, thereby improving the stability and grinding accuracy of the tool during the grinding process.

[0042] like Figure 1 to Figure 7 As shown, the adjustable tool holder for grinding tools on a CNC grinder provided by the present invention comprises:

[0043] The X-axis adjustment mechanism 1 includes two side plates 11 extending along the X-axis direction and a bottom plate 12 vertically installed between the two side plates 11; the bottom plate 12 is used to abut against the table surface of the workbench 5, and the two side plates 11 are used to clamp the left and right sides of the workbench 5 and are locked by a first bolt 15;

[0044] The Z-direction adjustment mechanism 3 comprises a box 36, in which a wedge mechanism for converting X-direction motion into Z-direction motion is arranged;

[0045] The Y-axis adjustment mechanism 2 includes a support plate 21, which is fixed on the X-axis adjustment mechanism 1 and connected to the bottom plate 31 of the box body 36 through a dovetail mechanism 22, and the dovetail mechanism 22 extends along the Y-axis direction;

[0046] The tool support block fine-tuning mechanism 4 is connected to the top of the bevel mechanism, and a tool support block 43 for clamping the tool 6 is provided on its top; the tool support block fine-tuning mechanism 4 includes a Z-axis rotation mechanism and a Y-axis rotation mechanism, the Z-axis rotation mechanism is used to drive the tool support block 43 to rotate on the XY plane, and the Y-axis rotation mechanism is used to drive the tool support block 43 to rotate on the XZ plane.

[0047] The adjustable tool bracket provided by the present invention includes an X-axis adjustment mechanism 1, a Y-axis adjustment mechanism 2, and a Z-axis adjustment mechanism 3, which are connected to each other. The X-axis adjustment mechanism 1 enables the tool support block fine-adjustment mechanism 4 to move relative to the workbench 5 along the X-axis direction, the Y-axis adjustment mechanism 2 enables the tool support block fine-adjustment mechanism 4 to move relative to the workbench 5 along the Y-axis direction, and the Z-axis adjustment mechanism 3 can move relative to the workbench 5 along the Z-axis direction.

[0048] like Figure 1 As shown, after the adjustable tool holder is installed on the workbench 5, the tabletop of the workbench 5 is supported below the bottom plate 12, and the two side plates 11 of the X-axis adjustment mechanism 1 are clamped on the left and right sides of the workbench 5. In some embodiments, at least one side plate 11 is provided with a through bolt hole, which is used for the insertion and adjustment and tightening of the first bolt 15. The bottom surface of the bottom plate 12 fits with the tabletop of the workbench 5; the inner side surfaces of the two side plates 11 fit with the left and right sides of the workbench 5 respectively, and the first bolt 15 passes through the bolt through hole, and the end thereof abuts against the side of the workbench 5. When the first bolt 15 is tightened, its end is tightly attached to the side of the workbench 5 or embedded in the hole on the side of the workbench 5, thereby ensuring that the X-axis adjustment mechanism 1 remains fixed relative to the workbench 5; once the first bolt 15 is loosened, its end will be detached from the side of the workbench 5, and at this time, the X-axis adjustment mechanism 1 can be easily pushed to slide on the surface of the workbench 5.

[0049] like Figure 2 As shown, in some embodiments, the X-axis adjustment mechanism 1 is further provided with a support plate 13 for carrying the Y-axis adjustment mechanism 2, and the support plate 13 is arranged above the bottom plate 12 and parallel to the bottom plate 12. The support plate 13 is vertically installed between the two side plates 11, located above the bottom plate 12, and an installation space is reserved between the support plate 13 and the bottom plate 12; the support plate 13 is connected to the support plate 21 by bolts. The purpose of this design is to realize the installation of the Y-axis adjustment mechanism 2 on the X-axis adjustment mechanism 1 by setting the support plate 13. The present invention connects the Y-axis adjustment mechanism 2 with the X-axis adjustment mechanism 1 by bolts. Specifically, the support plate 13 is installed above the bottom plate 12, and the support plate 21 is fixed to the support plate 13 by bolts, and the end of the bolt is located in the installation space between the support plate 13 and the bottom plate 12.

[0050] like Figure 2As shown, in some embodiments, the X-axis adjustment mechanism 1 is further provided with a reinforcing plate 14, which is located between the support plate 13 and the bottom plate 12, and is respectively perpendicular to and abuts against the support plate 13, the bottom plate 12, and the side plate 11. The provision of the reinforcing plate 14 enhances the structural stability of the X-axis adjustment mechanism 1, and ensures that the X-axis adjustment mechanism 1 has sufficient rigidity and anti-deformation capability when performing X-axis and Y-axis adjustments. Adding the reinforcing plate 14 between the bottom plate 12 and the support plate 13 can effectively disperse the pressure on the support plate 13, transfer it to the bottom plate 12 through the reinforcing plate 14, and then transfer it to the workbench 5 in contact with the bottom plate 12, thereby reducing stress concentration and extending the service life of the support plate 13.

[0051] like Figure 5 As shown, in some embodiments, the dovetail mechanism 22 is composed of a strip-shaped dovetail groove and a strip-shaped dovetail tenon, and the dovetail groove and the dovetail tenon are respectively configured on the box bottom plate 31 and the support plate 21. Specifically, the dovetail groove and the dovetail tenon are respectively configured on the support plate 21 and the box bottom plate 31. The design of this dovetail mechanism 22 enables the box bottom plate 31 and the support plate 21 to achieve precise relative movement. The cooperation of the dovetail groove and the dovetail tenon not only ensures the stability of the structure, but also allows fine-tuning within a certain range to adapt to different work requirements. For example, in precision machining, this structure can be used to adjust the relative position between the tool and the workpiece to ensure machining accuracy. In addition, due to the large contact area between the dovetail groove and the dovetail tenon, this structure also has good load-bearing capacity and impact resistance, and is suitable for use in a grinding environment with large vibrations. This design of the present invention can effectively extend the service life of the adjustable tool holder and reduce maintenance costs.

[0052] like Figure 4 As shown, in some embodiments, a clamping block 23 is provided at both ends of the dovetail mechanism 22, and the two clamping blocks 23 are respectively configured with a rectangular spring or a locking bolt. This design allows the user to control the displacement between the box bottom plate 31 and the support plate 21 by adjusting the tension of the rectangular spring and the tightness of the locking bolt. The use of the locking bolt can prevent the sliding parts from accidentally displacing under high load or vibration conditions, thereby enhancing the stability and safety of the structure. Through this dual adjustment mechanism, the dovetail mechanism 22 not only improves the precision of machining, but also improves the reliability and durability of the overall equipment.

[0053] like Figure 5As shown, in some embodiments, a Z-direction channel and an X-direction channel are provided inside the box 36; the inclined wedge mechanism includes an upper dovetail inclined wedge block 34 and a lower dovetail inclined wedge block 33, the upper dovetail inclined wedge block 34 is arranged in the Z-direction channel, and the lower dovetail inclined wedge block 33 is arranged in the X-direction channel, and the two are connected by an inclined dovetail surface. The upper dovetail inclined wedge block 34 and the lower dovetail inclined wedge block 33 are used in combination, so that the Z-direction adjustment mechanism 3 can achieve precise vertical direction (Z-direction) displacement adjustment.

[0054] like Figure 5 As shown, in some embodiments, the Z-direction adjustment mechanism 3 also includes two first thrust bolts 35 on the left and right sides of the box body 36. The first thrust bolts 35 extend along the X-axis direction, one end of which is located inside the box body 36 and abuts against the lower dovetail wedge block 33. The other end of the first thrust bolt 35 extends out of the box body 36. By rotating the nut, pressure can be applied to the first thrust bolt 35, thereby pushing the lower dovetail wedge block 33 to move along the X-axis direction. This design allows the user to finely adjust the position of the lower dovetail wedge block 33 in the X-axis direction by rotating the first thrust bolt 35, and then adjust the position of the upper dovetail wedge block 34 in the Z-axis direction, thereby improving the flexibility and accuracy of workpiece positioning. Through this structural design, the Z-direction adjustment mechanism 3 can more accurately control the position of the workpiece to meet the needs of high-precision processing.

[0055] like Figure 5 As shown, in some embodiments, two jacking bolt seats 32 are respectively provided outside the box body 36, and threaded holes are provided on the jacking bolt seats 32, and the threaded holes are used for the first jacking bolt 35 to pass through and be tightened. The purpose of designing the jacking bolt seats 32 in the present invention is to set the operating end of the first jacking bolt 35 outside the box body 36, so that the user can adjust the position of the lower dovetail wedge block 33 inside the box body 36 in the X-axis direction by rotating the end of the first jacking bolt 35 outside the box body 36, thereby realizing precise control of the Z-direction position of the workpiece.

[0056] In some embodiments of the present invention, the Z-axis rotation mechanism includes a positioning seat 41 and a center seat 42 arranged above the positioning seat 41; the positioning seat 41 is connected to the box body 36 by four guide rods 44 on all sides, and a center positioning pin 411 is installed on the top of the positioning seat 41; a V-shaped notch 421 for engaging the center positioning pin 411 is opened on one side of the center seat 42, and a spring clamping device is connected to the opposite side wall; the spring clamping device includes a first limit block 45 and a first spring 46, the lower part of the first limit block 45 is connected to the side wall of the positioning seat 41 by bolts, and the first spring 46 is connected between the first limit block 45 and the center seat 42, pressing the V-shaped notch 421 against the center positioning pin 411 and allowing the center seat 42 to rotate around the center positioning pin 411. With such a configuration, the V-shaped notch 421 can be closely attached to the center positioning pin 411 and effectively rotate around the center positioning pin 411. Figure 3 As shown, the tool support block fine-tuning mechanism 4 includes a positioning seat 41, a center seat 42 and a tool support block 43 from bottom to top; a through slot is provided at the center of the positioning seat 41, and an L-shaped support frame 414 is connected to the center of the bottom surface of the center seat 42. The L-shaped support frame 414 passes through the through slot and leaves a rotatable space, and the bottom surface of its short arm is against the top surface of the inclined wedge mechanism. In addition, the top surface of the short arm of the L-shaped support frame 414 is also connected to the positioning seat 41 through a second spring 415. Specifically, a connecting plate 416 is provided between the positioning seat 41 and the center seat 42, and the bottom of the connecting plate 416 is fixed to the positioning seat 41 by bolts, and is connected to the upper surface of the short arm of the L-shaped support frame 414 through the second spring 415. In this way, the elastic force direction of the second spring 415 is converted into a downward pulling force on the center seat 42, ensuring that the lower surface of the center seat 42 can fit tightly against the upper surface of the positioning seat 41. Furthermore, a second limit block 412 is provided on the side wall of the positioning seat 41, the lower part of the second limit block 412 is fixed to the side wall of the positioning seat 41 near the first limit block 45 by bolts, and the upper part is provided with a second jacking bolt 413. The second jacking bolt 413 passes through the first limit block 45 and then the top end abuts against the side wall of the center seat 42, and the second jacking bolt 413 is perpendicular to the line connecting the center positioning pin 411 and the first spring 46. When the jacking bolt is rotated, the center seat 42 can rotate around the center positioning pin 411.

[0057] In some embodiments of the present invention, the Y-axis rotation mechanism includes a lifting rod 423 extending along the Z-axis direction and an eccentric rotating shaft 424 extending along the XY plane. The top end of the lifting rod 423 abuts against one end of the tool support block 43, and the bottom end abuts against the eccentric rotating shaft 424.

[0058] like Figure 3 As shown, the tool support block 43 has a Y-shaped structure, including a plate-shaped root portion 431 and a left cantilever portion 432 and a right cantilever portion 433, and a strip-shaped tool groove 434 is formed between the two cantilever portions. Figure 4 As shown, a first supporting step 422 is provided on the top of the center seat 42, and the first supporting step 422 is supported on the bottom of the left cantilever portion 432, and the bottom of the right cantilever portion 433 is supported on the push block 47. After the push block 47 and the first supporting step 422 are installed in place, the root 431 of the tool support block 43 is clamped to prevent it from shaking left and right.

[0059] like Figure 5As shown, the top of the center seat 42 is also provided with a second support step 425 whose height is lower than the first support step 422, and the second support step 425 is supported on one side of the bottom of the root 431. The lifting push rod 423 of the tool support block fine-tuning mechanism 4 extends along the Z-axis direction, and the eccentric shaft 424 extends along the X-axis direction. The top end of the lifting push rod 423 abuts against the other side of the bottom of the root 431, and the bottom end abuts against the eccentric shaft 424. Specifically, an L-shaped channel is provided in the positioning seat 41, and the eccentric shaft 424 is installed in the X-direction channel of the L-shaped channel. The lifting push rod 423 is installed in the Z-direction channel of the L-shaped channel and passes through the center seat 42, and the top end abuts against the bottom of the root of the tool support block 43. With such arrangement, the lifting push rod 423 can be raised or lowered by rotating the eccentric rotating shaft 424, thereby adjusting the height of one end of the tool groove 434. At this time, the height of the side of the tool support block 43 supported by the second supporting step 425 remains unchanged. Therefore, the angle of the tool groove 434 is tilted, which can better fit the tool 6.
