Description

Technical Field

[0001] The present invention relates to the technical field of grinding machines, and in particular to a fixture capable of improving the grinding accuracy of a tool and a grinding machine using the fixture. Background Art

[0002] As we all know, grinders are machine tools used to grind workpiece surfaces and are widely used in the machining industry. Grinding is a common method of tool processing, typically performed on a cylindrical grinder. During processing, the tool is placed horizontally in the working area of the cylindrical grinder, and the grinding wheel on the cylindrical grinder grinds the side of the tool.

[0003] However, the fixture currently used by grinders to clamp cutting tools for grinding is not universal due to the inconsistent thickness of the blades of different cutting tools. That is, when the tool handle is clamped in the fixture, the fixture cannot be fine-tuned according to the thickness of the blade so that the other cutting surface of the blade being ground cannot better fit the mechanism that abuts the cutting surface. As a result, the tool generates greater vibration during the grinding process, resulting in poor blade grinding effect. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a fixture that can improve the grinding accuracy of a tool and a grinding machine using the fixture, which helps to improve the grinding quality of the tool surface.

[0005] According to an embodiment of the first aspect of the present invention, a fixture capable of improving tool grinding accuracy is provided, comprising:

[0006] Mounting plate;

[0007] The fixing mechanism includes a clamping mechanism for clamping the tool handle and a suspension mechanism provided on the clamping mechanism, the suspension mechanism is installed on the mounting plate, and the clamping mechanism is movably connected to the suspension mechanism;

[0008] The blade body placement mechanism is installed on the installation plate and is arranged adjacent to the clamping mechanism.

[0009] A fixture that can improve the grinding accuracy of cutting tools according to an embodiment of the present invention has at least the following beneficial effects: because the blade has a certain thickness and the thickness of each cutting tool is different, when the user fixes the cutting tool on the fixing mechanism, the blade placement mechanism is fixed to the mounting plate, and the clamping mechanism for clamping the tool handle is provided with a suspension mechanism. When the cutting tool is fixed to the fixture, only one blade surface of the blade needs to be placed in contact with the blade placement mechanism. When the tool handle is clamped by the clamping mechanism, the suspension mechanism can move the clamping mechanism so that the axis of the blade handle and the axis of the blade are always on the same balance axis, thereby avoiding excessive vibration of the blade during the grinding process due to insufficient stability, resulting in poor grinding quality. At the same time, it can also avoid the need for repeated positioning, and the structure is compact and practical.

[0010] According to an embodiment of the present invention, a clamp capable of improving tool grinding accuracy is provided. The clamping mechanism includes a mounting seat, a clamping cylinder mounted on the mounting seat, and a clamping seat. The driving end of the clamping cylinder is connected to the clamping seat.

[0011] According to an embodiment of the present invention, a clamp capable of improving the grinding accuracy of a tool is provided. The clamping seat is provided with a receiving groove for clamping a tool handle. The receiving groove is provided with a protrusion. The protrusion is embedded in the groove of the tool handle and abuts against the tool handle. The receiving groove on the clamping seat can realize the rapid positioning and fixing of the tool handle. It should be noted that the receiving groove and the tool handle are matched. In addition, the receiving groove is provided with a protrusion. At the same time, the rod body of the tool handle is provided with a groove that matches the protrusion, so that the tool handle can be quickly positioned and installed in the receiving groove. At the same time, it can also prevent the tool handle and the receiving groove from rotating relative to each other, which would cause the blade and the blade placement mechanism to deviate relative to each other and affect the grinding quality of the blade surface. The structure is simple and practical.

[0012] According to an embodiment of the present invention, a clamp capable of improving the grinding accuracy of a tool comprises a suspension mechanism comprising a base connected to a mounting plate, a slider movably connected to the base, and a connecting rod inserted through the slider, one end of the connecting rod being connected to the mounting seat. Since the slider of the suspension mechanism is slidably connected to the base, and the mounting seat and the slider are connected via the connecting rod, when the clamping mechanism clamps the tool handle, the tool handle causes the clamping mechanism to shift, i.e., the clamping mechanism, driven by the tool handle, causes the slider and the mounting seat to slide, thereby adjusting the position of the clamping mechanism so that the axis of the tool handle and the axis of the blade are always on the same equilibrium axis, so that the blade surface is always in contact with the blade placement mechanism, thereby improving the grinding quality of the tool.

[0013] A clamp for improving tool grinding accuracy, according to an embodiment of the present invention, further includes a second cylinder mounted on the base, the driving end of the second cylinder being connected to the other end of a connecting rod. When the clamping mechanism completes position adjustment, the second cylinder activates and pulls down the connecting rod, tightening and securing the mounting base, slider, and base in sequence. This prevents movement between the clamping mechanism and the suspension mechanism, and between the slider within the suspension mechanism and the mounting base, thereby enhancing tool clamping stability.

[0014] A fixture for improving tool grinding accuracy according to an embodiment of the present invention also includes a guide rod, one end of which is fixed to a mounting base and the other end of which is movably inserted into a guide hole of a slider. The guide rod serves as a guide when a second cylinder tightens and secures the mounting base and the slider to the base, thereby helping to ensure tool grinding quality.

[0015] According to an embodiment of the present invention, a fixture capable of improving tool grinding accuracy is provided. The blade placement mechanism includes a fixed base and a blade support platform disposed on the fixed base. The outer contour of the blade support platform is similar to that of the blade.

[0016] According to a second aspect of the present invention, a grinding machine is provided, comprising the aforementioned fixture capable of improving tool grinding accuracy.

[0017] According to an embodiment of the present invention, a grinding machine has at least the following beneficial effects: because the blade has a certain thickness, when the user fixes the tool on the fixing mechanism, the blade placement mechanism is fixed to the mounting plate, and the clamping mechanism for clamping the tool handle is provided with a suspension mechanism. When the tool is fixed to the fixture, only one blade surface of the blade needs to be placed in contact with the blade placement mechanism. When the tool handle is clamped by the clamping mechanism, the suspension mechanism can move the clamping mechanism so that the axis of the tool handle and the axis of the blade are always on the same balance axis, thereby avoiding excessive vibration of the blade during grinding due to insufficient stability, resulting in poor grinding quality.

[0018] A grinding machine according to an embodiment of the present invention further includes an ejection mechanism disposed on the grinding machine. The ejection mechanism includes an ejection drive, an ejection rod mounted on the ejection mechanism, and a pressure plate mounted on the ejection rod, one side of the pressure plate abutting against the blade. During the grinding process, the contact between the grinding wheel and the tool causes the tool to vibrate. The ejection mechanism continuously pushes against the tool during the grinding process, ensuring that the blade surface is always in contact with the blade support mechanism, further ensuring the quality of the tool grinding.

[0019] In a grinding machine according to an embodiment of the present invention, the pressing sheet is elastic and has a smooth surface, which helps to prevent the pressing sheet from scratching the cutting surface of a tool.

The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0064] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0065] Reference Figures 1 to 9 An embodiment of the present invention provides a fixture that can improve the grinding accuracy of a tool, comprising: a mounting plate 1; a fixing mechanism, the fixing mechanism comprising a clamping mechanism for clamping a tool handle 5-1 and a suspension mechanism arranged on the clamping mechanism, the suspension mechanism being mounted on the mounting plate 1, and the clamping mechanism being movably connected to the suspension mechanism; a blade placement mechanism, mounted on the mounting plate 1, and the blade placement mechanism being arranged adjacent to the clamping mechanism.

[0066] Because the blade 5-3 has a certain thickness and the thickness of each tool 5 is different, when the user fixes the tool 5 on the fixing mechanism, since the blade placement mechanism is fixed on the mounting plate 1, and the clamping mechanism for clamping the tool handle 5-1 is provided with a suspension mechanism, when the tool 5 is fixed to the fixture, it is only necessary to place one blade surface of the blade 5-3 in contact with the blade placement mechanism. When the tool handle 5-1 is clamped by the clamping mechanism, the suspension mechanism can move the clamping mechanism so that the axis of the tool handle 5-1 and the axis of the blade 5-3 are always on the same balance axis, thereby avoiding excessive vibration of the blade 5-3 during the grinding process due to insufficient stability, resulting in poor grinding quality, and also avoiding the need for repeated positioning. The structure is compact and practical.

[0067] According to some embodiments of the present application, the clamping mechanism includes a mounting base 2, a clamping cylinder 3 mounted on the mounting base 2, and a clamping base 4. The driving end of the clamping cylinder 3 is connected to the clamping base 4. The clamping base 4 is provided with a receiving groove 4-1 for clamping the tool handle 5-1. The receiving groove 4-1 is provided with a protrusion 4-2. The protrusion 4-2 is embedded in the groove 5-2 of the tool handle 5-1 and abuts against the tool handle 5-1. The accommodating groove 4-1 on the clamping seat 4 can realize the rapid positioning and fixation of the knife handle 5-1. It should be noted that the accommodating groove 4-1 is matched with the knife handle 5-1. In addition, a protrusion 4-2 is provided in the accommodating groove 4-1. At the same time, a groove 5-2 matching the protrusion 4-2 is provided on the rod body of the knife handle 5-1, so that the knife handle 5-1 can be quickly positioned and installed with the accommodating groove 4-1. At the same time, it can also prevent the knife handle 5-1 and the accommodating groove 4-1 from rotating relative to each other, so as to cause the blade 5-3 and the blade placement mechanism to be relatively offset, thereby affecting the grinding quality of the blade surface. The structure is simple and practical.

[0068] According to some embodiments of the present application, Figure 9 As shown, a bayonet 2-1 is further provided at one end of the mounting seat 2, and the connection point between the blade body 5-3 and the handle 5-1 is connected at the bayonet 2-1, and in order to prevent the tool from being scratched, a smooth gasket 2-2 is provided at the bayonet 2-1.

[0069] According to some embodiments of the present application, the suspension mechanism includes a base 6 connected to the mounting plate 1, a slider 7 movably connected to the base 6, and a connecting rod 8 inserted through the slider 7, one end of the connecting rod 8 being connected to the mounting seat 2. Since the slider 7 of the suspension mechanism is slidably connected to the base 6, and the mounting seat 2 is connected to the slider 7 via the connecting rod 8, when the clamping mechanism clamps the tool handle 5-1, the tool handle 5-1 causes the clamping mechanism to shift, that is, the clamping mechanism causes the slider 7 and the mounting seat 2 to slide under the drive of the tool handle 5-1, so as to adjust the position of the clamping mechanism so that the axis of the tool handle 5-1 and the axis of the blade 5-3 are always on the same equilibrium axis, so that the blade surface is always in contact with the blade placement mechanism, thereby improving the grinding quality of the tool 5.

[0070] According to some embodiments of the present application, a second cylinder 9 is further included, which is mounted on the base 6. The driving end of the second cylinder 9 is connected to the other end of the connecting rod 8. When the clamping mechanism completes the position adjustment, the second cylinder 9 is activated and pulls down the connecting rod 8, so that the mounting base 2, the slider 7, and the base 6 are tightened and fixed in sequence, preventing the clamping mechanism and the suspension mechanism, and the slider 7 in the suspension mechanism and the mounting base 2 from moving, thereby enhancing the clamping stability of the tool 5.

[0071] According to some embodiments of the present application, a guide rod 10 is further included, one end of which is fixed to the mounting base 2 and the other end of which is movably inserted into the guide hole 7-1 of the slider 7. The guide rod 10 serves as a guide when the second cylinder 9 tightens and secures the mounting base 2 and the slider 7 to the base 6, thereby helping to ensure the grinding quality of the tool 5.

[0072] According to some embodiments of the present application, the blade placement mechanism includes a fixed base 116 and a blade 5-3 supporting platform arranged on the fixed base 116, and the outer contour of the blade 5-3 supporting platform is similar to the outer contour of the blade 5-3.

[0073] According to some embodiments of the present application, Figure 6 and Figure 7 As shown, the base 6 is provided with a wedge-shaped groove 6 - 1 , and the slider 7 is provided with a wedge block 7 - 2 which is mounted in cooperation with the wedge-shaped groove 6 - 1 .

[0074] According to some embodiments of the present application, Figures 3 to 7 As shown, a locking mechanism is also provided, which includes a third cylinder and a connecting plate 24 for fixing the third cylinder to the clamping mechanism. In addition, a semicircular groove is provided on one side of the base 6 and the slider 7. The two semicircular grooves are mirrored to form a through hole for the movable end of the third cylinder to pass through. When the tool 5 is fixed, the movable end of the third cylinder is inserted from the through hole until it abuts against the wedge block 7-2, which can lock the suspension mechanism and further ensure the grinding quality of the tool 5.

[0075] The present application also provides a grinding machine using the above-mentioned fixture, wherein the main body of the grinding machine is not shown in the figure. Figure 10 , Installation diagram of the fixture and the ejection mechanism, the fixture and the ejection mechanism are connected to the control cabinet of the grinder body, and the fixture is installed on the grinder body through the mounting plate 1.

[0076] According to some embodiments of the present application, Figures 10 to 12 As shown, the ejection mechanism of the present application includes an ejection drive 13, an ejection rod 14 mounted on the ejection mechanism, and a pressure plate 16 mounted on the ejection rod 14. One side of the pressure plate 16 abuts against the blade body 5-3. During the grinding process, the contact between the grinding wheel and the blade 5 causes the blade 5 to vibrate. The ejection mechanism constantly pushes the blade 5 during the grinding process, ensuring that the blade surface is always in contact with the blade body placement mechanism, further ensuring the grinding quality of the blade 5.

[0077] According to some embodiments of the present application, the pressing sheet 16 is elastic and has a smooth surface, which helps prevent the pressing sheet 16 from scratching the blade surface of the tool 5. At the same time, because the pressing sheet 16 is elastic and, when the pressing sheet 16 is pressed against the blade surface, the pressing sheet 16 and the tool 5 form an interference fit, that is, the pressing sheet 16 is in a bent state, so that the pressing sheet 16 can always push the blade body 5-3 during the grinding process of the tool 5 by relying on its own resilience.

[0078] According to some embodiments of the present application, the push mechanism is further provided with an adjustment mechanism, wherein, as shown in the figure, the adjustment mechanism includes a saddle 18 provided with a slide groove 18-1, a movable block 19 is provided in the slide groove 18-1, a first translation mechanism is mounted on the movable block 19, and the movable block 19 can drive the first translation mechanism to move. In addition, specifically as shown in the figure, the first translation mechanism is composed of a fixed block 20 and an adjustment block 21 provided with an inclined surface, wherein the fixed block 20 is mounted on the movable block 19, and the adjustment block 21 is provided with an adjustment groove 21-1. The fixed block 20 is connected to the adjustment block 21 by bolts and can be moved to adjust the position of the adjustment block 21 through the adjustment groove 21-1. In addition, as shown in the figure, the pressing plate 16 is mounted on the inclined surface of the adjustment block 21 by bolt fixing. At the same time, two pressing plates 22 are provided on the upper and lower sides of the pressing plate 16; the third cylinder 23 can enhance the installation stability of the pressing plate 16. In addition, the pressing plate 16 is also provided with a strip groove 15 for adjusting the position of the pressing plate 16.
