Description

Technical Field

[0001] This invention relates to a clamping block, and more particularly to an adjustable clamping block for a cutting bed. Background Technology

[0002] Chinese patent application number 2024102234178 discloses a cutting bed cutter head with a cutting bed cutter guide seat. The cutting bed cutter head includes a cutter head body and a cutting blade guide structure. The cutting blade guide structure includes an upper guide block and a lower guide block. The upper guide block is fixedly mounted on top of the lower guide block. An elongated cutting blade guide groove is provided on one side of the upper guide block in the vertical direction. Grinding block mounting notches are provided on both sides of the cutting blade guide groove, and grinding blocks are installed in the grinding block mounting notches. A cutting blade guide channel is provided on the lower guide block. This cutting bed cutter head can achieve efficient cooling of the cutting blade, timely removal of dirt, efficient grinding, and enables the cutting bed to achieve higher quality drilling and thicker cutting. Figure 1 As shown, in the above structure, the cutter b on the cutting head a is prone to skew after passing through the cutter guide structure c. The current structure cannot fine-tune the cutter b, relying solely on the precision of the initial design. This places very high demands on the design and significantly increases design costs. If the cutter b is not perpendicular, for example, when cutting a circular piece of fabric, such as... Figure 2 As shown, the cut fabric pieces d will be of different sizes, with the upper circular piece being larger than the lower one. This makes it impossible to sew the two circular pieces together later, resulting in a seriously substandard cut. Therefore, calibrating the cutting blade before cutting is crucial, but currently there is no good technical solution to address this problem. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an adjustable clamping block for cutting beds that can correct the perpendicularity of the cutting blades on the cutting bed.

[0004] The technical solution adopted in this invention is as follows: This invention includes a clamping block body, on which a vertical blade hole for a cutting bed blade to pass is provided, and a horizontal mounting hole communicating with the vertical blade hole is provided on the clamping block body. A cutting bed guide mechanism is provided in the horizontal mounting hole, and an adjustment mechanism for pushing the cutting bed guide mechanism to move horizontally is also provided in the horizontal mounting hole. In use, the cutting bed blade passes through the upper end of the vertical blade hole, passes through the cutting bed guide mechanism, and then exits from the lower end of the vertical blade hole.

[0005] Furthermore, the horizontal mounting hole is a circular through hole, and the cutting blade guiding mechanism includes a guide wheel and a rotating shaft passing through the center of the guide wheel. An annular guide groove is provided on the outer circumference of the guide wheel. In use, one side of the cutting blade rests in the annular guide groove. A left bearing and a right bearing are respectively provided at both ends of the rotating shaft. The left bearing and the right bearing are slidably disposed in the horizontal mounting hole.

[0024] like Figures 3 to 10As shown, in this embodiment, the present invention includes a clamping block body 1, on which a vertical blade hole 2 for a cutting blade to pass is provided, and a horizontal mounting hole 3 communicating with the vertical blade hole 2 is provided on the clamping block body 1. A cutting blade guide mechanism 4 is provided in the horizontal mounting hole 3, and an adjustment mechanism 5 for pushing the cutting blade guide mechanism 4 to move horizontally is also provided in the horizontal mounting hole 3. In use, the cutting blade passes through the upper end of the vertical blade hole 2, passes through the cutting blade guide mechanism 4, and exits from the lower end of the vertical blade hole 2. When it is found that the verticality of the cutting blade does not meet the requirements, the cutting blade guide mechanism 4 can be adjusted. Through the adjustment mechanism 5 that moves the cutting blade guide mechanism 4 horizontally, the verticality of the cutting blade can be adjusted.

[0025] In this embodiment, the horizontal mounting hole 3 is a circular through hole. The cutting blade guiding mechanism 4 includes a guide wheel 6 and a rotating shaft 7 passing through the center of the guide wheel 6. An annular guide groove 8 is provided on the outer circumference of the guide wheel 6. In use, one side of the cutting blade rests in the annular guide groove 8. A left bearing 9 and a right bearing 10 are respectively provided at both ends of the rotating shaft 7. The left bearing 9 and the right bearing 10 are slidably disposed in the horizontal mounting hole 3. The adjusting mechanism 5 adjusts the horizontal movement of the guide wheel 6 by pushing the left bearing 9 or the right bearing 10. When the cutting blade moves up and down and comes into contact with the guide wheel 6, the guide wheel 6 can rotate accordingly, thereby reducing the friction between the cutting blade and the guide wheel 6.

[0026] In this embodiment, the adjustment mechanism 5 includes a left adjustment mechanism 11 and a right adjustment mechanism 12, which are located at both ends of the horizontal mounting hole 3. Each of the left and right adjustment mechanisms includes a fixing block 13, a bearing pushing block 14, and an adjusting screw 15. The clamping block body 1 is provided with a left insertion hole 16 and a right insertion hole 17 at both ends of the horizontal mounting hole 3. The left insertion hole 16 and the right insertion hole 17 are both connected to and perpendicular to the horizontal mounting hole 3. The fixing block 13 of the left adjustment mechanism 11 and the fixing block 13 of the right adjustment mechanism 12 are respectively inserted into the left insertion hole 16 and the right insertion hole 17. The adjusting screw 15 is threadedly connected to the fixing block 13, and the adjusting screw 15 passes through one end of the fixing block 13 and abuts against one side of the bearing pushing block 14. The other side of the bearing pushing block 14 abuts against the side of the left bearing 9 or the right bearing 10. In this embodiment, the left bearing 9 and the right bearing 10 are both deep groove ball bearings. In this embodiment, the verticality of the cutting blade on the cutting bed can be finely adjusted by adjusting the adjusting screw 15. At the same time, the fixing block 13 can be well fixed in the left insertion hole 16 or the right insertion hole 17 under the reaction of the adjusting screw 15. This can effectively reduce the use of parts and reduce the overall size of the invention, thereby improving the convenience and versatility of use.

[0027] In this embodiment, the bearing push block 14 is cylindrical, and an annular protrusion 18 is provided on the side of the bearing push block 14 that contacts the left bearing 9 or the right bearing 10. The annular protrusion 18 abuts against the outer ring side of the left bearing 9 or the outer ring side of the right bearing 10. This design ensures that the rotation of the inner ring of the left bearing 9 and the inner ring of the right bearing 10 is not affected, meaning that no resistance is added to the guide wheel 6 during operation or adjustment.

[0028] In this embodiment, a pair of needle roller bearings 19 are provided on the inner wall of the lower outlet of the vertical cutter hole 2. During use, these needle roller bearings 19 are located on both sides of the cutting blade. In this embodiment, a protruding extension 20 is provided at the lower end of the vertical cutter hole 2, and the needle roller bearings 19 are mounted on the protruding extension 20. The design of the protruding extension 20 allows the supporting part of the cutting blade to be closer to the fabric, further increasing the stability of the cutting blade. Simultaneously, the design of the needle roller bearings 19 effectively reduces friction between the cutting blade and the vertical cutter hole 2, further extending the service life of the cutting blade.

[0029] In this embodiment, a sealing gasket 21 and a copper sleeve 22 are fitted onto the protruding extension 20. The sealing gasket 21 is located above the copper sleeve 22, and the copper sleeve 22 positions the sealing gasket 21 and prevents the needle roller bearing 19 from falling out of the mounting hole. In this embodiment, the sealing gasket 21 is used to prevent water mist from entering the underside of the clamping block body 1 during atomized cooling of the cutter disc, thus avoiding malfunctions.

[0030] In this embodiment, the clamping block body 1 is further provided with two elongated vertical mounting holes 23, which are located on both sides of the vertical blade hole 2. In this embodiment, the cutting blade of the cutting bed is roughly aligned through the two elongated vertical mounting holes 23.

[0031] like Figure 9 and Figure 10 As shown, in this embodiment, the clamping block body 1 is further provided with an auxiliary guide block mounting position 24, and an auxiliary guide block 25 is provided on the auxiliary guide block mounting position 24. The auxiliary guide block 25 is fixedly mounted on the top of the clamping block body 1. A long strip-shaped cutting guide groove 26 is provided on one side of the auxiliary guide block 25 in the vertical direction. Sharpening block mounting notches 27 are provided on both sides of the cutting guide groove 26, and sharpening blocks 28 are provided on the sharpening block mounting notches 27. The cutting guide groove 26 has an upper port, a lower port, and a side opening. The cutting blade is inserted into the groove from the upper port of the cutting guide groove 26 and exits from the lower port of the cutting guide groove 26. The back or edge of the cutting blade faces the side opening of the cutting guide groove 26. An oil storage cavity 30 is provided on the auxiliary guide block 25. The oil storage cavity 30 is filled with oil storage cotton. An oil outlet 29 communicating with the oil storage cavity 30 is provided at the bottom of the cutting guide groove 26. In this embodiment, by slowly permeating the lubricating oil through the oil-retaining cotton, a small amount of lubricating oil can adhere to the cutting blade of the cutting bed, reducing friction between the cutting blade and other components and preventing blade breakage.

[0032] Although the embodiments of the present invention are described with reference to actual solutions, they do not constitute a limitation on the meaning of the present invention. Modifications to the embodiments and combinations with other solutions based on this specification will be obvious to those skilled in the art.
