Description

Technical Field

[0001] This invention relates to the field of cutting tool processing technology, and in particular to a laser marking fixture for cutting tools. Background Technology

[0002] Current woodworking fixed-blade knives generally consist of a handle and a blade. The blade is coaxial with the handle, and has a cutting edge extending along its axis. During the manufacturing process, to differentiate woodworking fixed-blade knives, laser-engraved trademarks, model numbers, and tool parameters are required on the handle. Existing technology includes a laser marking fixture for knives, comprising a positioning block with a receiving groove for holding the handle. When the handle is placed in the receiving groove, its axis is parallel to the extension direction of the groove, and the handle rests against the two inner sidewalls of the groove. The worker places the woodworking fixed-blade knife axially into a predetermined position within the groove, thus positioning the knife to be laser-engraved. However, because the handle is cylindrical, the knife placed in the receiving groove can easily roll circumferentially during laser engraving, leading to laser failure.

[0003] Therefore, existing laser marking fixtures for cutting tools also include a cover plate with a pin underneath. The cover plate is placed on a positioning block and covers part of the receiving groove. When the tool handle is placed in the receiving groove, the pin can press down on the tool handle to prevent it from rolling. However, since the cover plate is mostly made of opaque iron, workers cannot determine whether the woodworking straight knife has been placed in the preset position in the receiving groove along its axis. That is, the woodworking straight knife is not accurately positioned along its axis, which causes the trademark, model, and tool parameters laser-etched on the tool handle to deviate from the preset laser area along the axis of the tool handle, reducing the manufacturing efficiency of woodworking straight knives.

[0004] Therefore, the above problems urgently need to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide a laser marking fixture for cutting tools. This laser marking fixture can prevent the cutting tool from rolling around the circumference of the tool holder during the laser marking process, and at the same time, it can prevent the laser marking on the tool holder from deviating from the preset laser marking area along the axial direction of the tool holder, thereby improving the manufacturing efficiency of the cutting tool.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A laser marking fixture for a cutting tool, the cutting tool comprising a shank and a blade, the blade being coaxially disposed with the shank, the blade having at least two cutting edges extending along its axis, all the cutting edges being uniformly arranged around the axis of the blade, the laser marking fixture for the cutting tool comprising:

[0008] A first positioning block, the first positioning block having a first receiving groove extending along its width direction, the first receiving groove having openings at both ends, the first receiving groove being configured to receive the blade, a second receiving groove being formed on the inner wall of either side of the first receiving groove, the second receiving groove being capable of receiving each of the blade edges, when the blade is received in the first receiving groove, the blade abuts against the inner wall of the other side of the first receiving groove; and

[0009] The second positioning block is disposed on one side of the first positioning block along its width direction. When the blade is placed into the first receiving groove, the end of the blade away from the handle abuts against the second positioning block.

[0010] Preferably, the cross-section of the first receiving groove is trapezoidal, and the bottom of the first receiving groove is the upper base of the trapezoid.

[0011] Preferably, the cross-section of the first receiving groove is rectangular, and the blade can extend into the first receiving groove from the end of the first receiving groove away from the second positioning block.

[0012] Preferably, a third receiving groove is provided on the inner wall of the other side of the first receiving groove, and the third receiving groove and the second receiving groove are arranged symmetrically.

[0013] Preferably, the walls of the first receiving groove, the second receiving groove, and the third receiving groove are all coated with a wear-resistant coating.

[0014] Preferably, a fourth receiving groove is provided at the bottom of the first receiving groove, the fourth receiving groove being configured to receive a suction member, the suction member being configured to apply a suction force to the blade after the blade is placed into the first receiving groove.

[0015] Preferably, the attracting element is a magnet.

[0016] Preferably, the laser marking fixture for the cutting tool is made of bakelite material.

[0017] Preferably, the first positioning block is provided with a plurality of first receiving slots at intervals along its length.

[0018] Preferably, the laser marking fixture for the cutting tool further includes a base plate, the first positioning block being detachably connected to the base plate, and the second positioning block being fixedly connected to the base plate.

[0019] The beneficial effects of the present invention are as follows: In the present invention, when the blade of the woodworking straight knife is placed in the first receiving groove, one side of the blade abuts against the inner wall of the first receiving groove where the second receiving groove is not opened, and at least one of the two cutting edges is received in the second receiving groove. This allows the first positioning block to prevent the woodworking straight knife from rolling around the handle when it is supporting the woodworking straight knife, while the second positioning block can position the woodworking straight knife along the axial direction of the handle, thereby improving the manufacturing efficiency of the tool.

[0036] Example 1

[0037] In the prior art, there is a woodworking straight knife, which includes a handle and a blade 110. The blade 110 is coaxially arranged with the handle and has at least two cutting edges 111 extending along its axis. All cutting edges 111 are evenly arranged around the axis of the blade 110. In order to laser-etch trademarks, models, and tool parameters on the handle, the prior art provides a laser marking fixture for the tool. The laser marking fixture for the tool includes a positioning block with a receiving groove that can receive the handle. The positioning block has a positioning line along the extension direction of the receiving groove. The worker places the handle of the woodworking straight knife into the receiving groove according to the indication of the positioning line to position the handle along the extension direction of the receiving groove. In order to prevent the woodworking straight knife from rolling around the handle, the laser marking fixture for the tool also includes a cover plate with a pin at the bottom. However, this may cause the trademarks, models, and tool parameters laser-etched on the handle to deviate from the laser area along the axial direction of the handle.

[0038] To solve the above problems, another positioning block can be set on one side of the positioning block of the laser marking fixture of the tool. One of the positioning blocks has the above-mentioned receiving groove, and the two ends of the receiving groove are provided with openings. When the woodworking straight knife is placed in the receiving groove, the end of the knife handle away from the blade 110 abuts against the other positioning block to position the woodworking straight knife along the axial direction of the knife handle. However, since the cover plate obstructs the operator's view, the operator needs to blindly push the woodworking straight knife along the extension direction of the receiving groove so that the end of the knife handle away from the blade 110 abuts against the other positioning block. This may damage the woodworking straight knife or the laser marking fixture of the tool. Therefore, a laser marking fixture that can position the woodworking straight knife along the circumference and axial direction of the knife handle without damaging the woodworking straight knife or the tool itself is needed.

[0039] Therefore, this embodiment provides a laser marking fixture for cutting tools. Please refer to [link / reference]. Figures 3 to 6 The laser marking fixture for the cutting tool includes a first positioning block 210 and a second positioning block 220. The first positioning block 210 is provided with a first receiving groove 211 extending along its width direction. The first receiving groove 211 has openings at both ends. The first receiving groove 211 is configured to receive the blade 110. A second receiving groove 212 is provided on the inner wall of either side of the first receiving groove 211. The second receiving groove 212 can receive each blade 111. When the blade 110 is received in the first receiving groove 211, the blade 110 abuts against the inner wall of the other side of the first receiving groove 211. The second positioning block 220 is provided on one side of the first positioning block 210 along its width direction. When the blade 110 is placed into the first receiving groove 211, the end of the blade 110 away from the handle abuts against the second positioning block 220.

[0040] In this embodiment, when the blade 110 of the woodworking straight knife is placed in the first receiving groove 211, one side of the blade 110 abuts against the inner wall of the first receiving groove 211 where the second receiving groove 212 is not opened. At least one of the two blades 111 is received in the second receiving groove 212, so that the first positioning block 210 can prevent the woodworking straight knife from rolling around the handle when it is carrying the woodworking straight knife. At the same time, the second positioning block 220 can position the woodworking straight knife along the axial direction of the handle, thereby improving the manufacturing efficiency of the tool.

[0041] It is understandable that, since the view at the contact point between the first positioning block 210 and the second positioning block 220 is not obstructed in this embodiment, this embodiment makes it easier for the operator to control the force when the end of the knife handle away from the blade 110 is brought against the second positioning block 220.

[0042] like Figure 1 and Figure 2 As shown, the blade tips of different woodworking straight knives have different orientations around the axis of the blade 110. Please refer to... Figure 3 and Figure 4 In order to accommodate woodworking straight knives with different blade tip arrangement directions, a third receiving groove 213 is provided on the inner wall of the other side of the first receiving groove 211 in this embodiment. The third receiving groove 213 and the second receiving groove 212 are symmetrically arranged. The second receiving groove 212 and the third receiving groove 213 can respectively accommodate the blade 111 with blade tips arranged clockwise and counterclockwise around the axis of the blade 110.

[0043] Please continue reading. Figure 5 The bottom of the first receiving groove 211 is provided with a fourth receiving groove 214. The fourth receiving groove 214 is configured to receive a suction member (not shown in the figure). The suction member is configured to apply a suction force to the blade 110 after the blade 110 is placed in the first receiving groove 211. When the blade 110 is placed in the first receiving groove 211, the suction member can effectively hold the blade 110, making the position of the woodworking straight knife more stable, so as to further prevent the woodworking straight knife from rolling around the handle, and at the same time prevent the woodworking straight knife from moving away from the second positioning block 220 along the axial direction of the handle.

[0044] Understandably, a woodworking double-edged straight knife with two cutting edges 111 also requires laser-etched graduation lines on the blade 110 located on one side of the cutting edge 111. This embodiment can perform laser etching on both the blade 110 and the handle in one go, further improving the manufacturing efficiency of the knife. After the graduation line on one side of one of the two cutting edges 111 is laser-etched, the worker takes out the woodworking double-edged straight knife and rotates it along the axis of the blade 110 so that the laser-etched cutting edge 111 can be placed in the second receiving groove 212 to laser-etch graduation lines on one side of the other cutting edge 111.

[0045] like Figures 3 to 6As shown, in this embodiment, the cross-section of the first receiving groove 211 is trapezoidal, and the bottom of the first receiving groove 211 is the upper base of the trapezoid. This embodiment provides two methods for placing a woodworking straight knife. One method is as follows: the worker places the tip of one blade 111 of the blade 110 toward the opening of the second receiving groove 212 extending along the width direction of the first positioning block 210, and places the blade 110 from the first receiving groove 211. One method involves placing the blade 111 above the first receiving groove 211, while simultaneously extending the tip of the blade 111 towards the second receiving groove 212 into the opening of the second receiving groove 212 extending along the width direction of the first positioning block 210; another method involves the worker inserting the end of the blade 110 away from the handle into the first receiving groove 211 through the opening at the end of the first receiving groove 211 away from the second positioning block 220, while simultaneously extending the end of one blade 111 away from the handle into the second receiving groove 212 through the opening at the end of the second receiving groove 212 away from the second positioning block 220. The worker then pushes the woodworking straight knife along the width direction of the first positioning block 210 until the end of the blade 110 away from the handle abuts against the second positioning block 220.

[0046] Since the cross-section of the first receiving groove 211 in this embodiment is trapezoidal, when a woodworking straight knife is placed in the first receiving groove 211, the blade 110 may not be able to contact the bottom of the first receiving groove 211. In order to enable the attracting element to effectively attract the blade 110, the attracting element in this embodiment is a magnet. By placing magnets of different heights in the fourth receiving groove 214, it is adapted to attract woodworking straight knives of different sizes.

[0047] Please see Figure 3 and Figure 4 In this embodiment, the laser marking fixture for the cutting tool also includes a base plate 230, a first positioning block 210 detachably connected to the base plate 230, and a second positioning block 220 fixedly connected to the base plate 230. This embodiment can adapt to different sizes of woodworking straight knives by replacing the first positioning block 210 with a first receiving groove 211 of different sizes.

[0048] In this embodiment, the laser marking fixture for the cutting tool is preferably made of bakelite. Compared to laser marking fixtures for cutting tools made of iron, the laser marking fixture for the cutting tool in this embodiment is lighter, has lower manufacturing costs, and facilitates the replacement of the first positioning block 210. It is understood that, since the end of the blade 110 furthest from the shank needs to abut against the second positioning block 220 in this embodiment, using bakelite would not easily damage the end of the blade 110.

[0049] Furthermore, in this embodiment, the walls of the first receiving groove 211, the second receiving groove 212 and the third receiving groove 213 are all coated with a wear-resistant coating to prevent the blade 110 from scratching the laser marking fixture of the tool.

[0050] To further improve the manufacturing efficiency of woodworking straight knives, such as Figure 3 and Figure 4 As shown, in this embodiment, the first positioning block 210 is provided with a plurality of first receiving grooves 211 at intervals along its length direction, so as to simultaneously laser-cut a plurality of woodworking straight knives.

[0051] Example 2

[0052] Compared to Example 1, please refer to Figure 7 In this embodiment, the cross-section of the first receiving groove 211 is rectangular. The blade 110 can extend into the first receiving groove 211 from the end away from the second positioning block 220. In this embodiment, the worker can only place the blade 110 into the first receiving groove 211 by pushing the woodworking straight knife along the width direction of the first positioning block 210. However, in this embodiment, the blade 110 can abut against the bottom of the first receiving groove 211. Compared with the first embodiment, this embodiment does not require replacing the magnet in the fourth receiving groove 214.

[0053] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
