Description

Technical Field

[0001] This application relates to the field of blade holder technology, and more particularly to a metal blade holder. Background Technology

[0002] Metal insert holders are components used to secure metal inserts to cutting tools or other devices. The design and use of these holders ensure cutting efficiency and stability, and also provide some protection for the cutting tool.

[0003] Existing metal blade holders consist of a mounting base, mounting slot, and fastening screws. Installation involves inserting the blade into the mounting slot and then securing it with screws. This process is simple and quick. However, certain drawbacks exist. Because the mounting slot matches the blade's thickness, a certain amount of force needs to be applied when inserting the blade, posing a safety hazard during installation. Furthermore, the screws, if loosened, can interfere with the use of the blade. Therefore, this application proposes a new metal blade holder. Utility Model Content

The side wall of the mounting base has a pair of grooves located on both sides of the insertion slot. Both grooves have guide holes. The inner walls of the two protrusions are fixedly connected to guide rods, and the two guide rods are slidably inserted into the two guide holes.

[0010] Preferably, the inner walls of both sides of the insertion groove are provided with inverted L-shaped sliding grooves, and the two clamping blocks are slidably connected in the two inverted L-shaped sliding grooves respectively. The upper ends of the two clamping blocks that are far apart from each other are fixedly connected to a transmission block. The two sides of the mounting base are threaded with first screws, and the inner ends of the two first screws are rotatably connected to the two transmission blocks respectively.

[0011] Preferably, the locking rod also passes through the corresponding transmission block, and a threaded cylinder is fixedly connected to the end of the transmission block away from the clamping block. A second screw is threadedly connected to the threaded cylinder, and the inner end of the second screw is connected to the locking rod. By rotating the second screw, the locking rod is pushed into the corresponding locking hole to complete the locking of the blade.

[0033] Example

[0034] like Figures 1-4 As shown, the present application proposes a metal blade fastener, which includes a mounting base 1 and a slot 2 formed on its upper end. Several sets of connecting blocks 4 are fixedly connected to the upper end of the mounting base 1 for connection and fixation when the mounting base 1 is installed. An insertion slot 10 is formed at the bottom end of the mounting base 1, and an insert 3 for supporting the blade 5 is installed in the insertion slot 10.

[0035] The inner walls on both sides of the insertion groove 10 are provided with clamping members 6. The clamping members 6 include clamping blocks 62 on both sides of the blade 5. One of the clamping blocks 62 is provided with a locking member 7 for locking the blade 5.

[0036] The side wall of the blade 5 is provided with a plurality of locking holes 51, and the locking member 7 includes a locking rod 71 that passes through the pressing block 62, and the locking rod 71 can pass through the corresponding locking hole 51.

[0037] Specifically, the insert 3 includes a mounting plate 31 that slides into the insertion slot 10. The bottom end of the mounting plate 31 has a slot for attracting and positioning the blade (the blade is made of steel and can attract the magnet). This positions the blade 5 before insertion, preventing it from detaching from the insert 3 before locking, thus ensuring stable installation. One end of the mounting plate 31 is fixedly connected to a side block 32, and both ends of the side block 32 are fixedly connected to protrusions 33. The side wall of the mounting base 1 has a pair of grooves located on both sides of the insertion slot 10. Both grooves have guide holes 34. The inner walls of the two protrusions 33 are fixedly connected to guide rods 35, which slide into the two guide holes 34. Before inserting the insert 3, the two guide rods 35 are first inserted into the two guide holes 34, providing guidance and limiting for the insertion of the insert 3.

[0038] Furthermore, the inner walls of both sides of the insertion groove 10 are provided with inverted L-shaped sliding grooves. The two clamping blocks 62 are slidably connected in the two inverted L-shaped sliding grooves respectively. The upper ends of the two clamping blocks 62, which are far apart from each other, are fixedly connected to the transmission blocks 61. The two side walls of the mounting base 1 are threaded with first screws 63. The inner ends of the two first screws 63 are rotatably connected to the two transmission blocks 61 respectively. By rotating the first screws 63, the transmission blocks 61 and clamping blocks 62 are pushed closer to the blade 5, so that the clamping blocks 62 abut against the blade 5. The two clamping blocks 62 abut against the two sides of the blade 5 respectively, completing the limitation of the blade 5 and preventing the blade 5 from shaking during use.

[0039] The locking rod 71 also passes through the corresponding transmission block 61. The end of the transmission block 61 away from the pressing block 62 is fixedly connected to a threaded cylinder 72. The threaded cylinder 72 is internally threaded with a second screw 73. The inner end of the second screw 73 is connected to the locking rod 71. By rotating the second screw 73, the locking rod 71 is pushed into the corresponding locking hole 51, thereby locking the blade 5.

[0040] It should be noted that a control groove 8 is provided on one side of the mounting base 1, and the threaded cylinder 72 and the second screw 73 are accommodated in the control groove 8. When the transmission block 61 and the clamping block 62 move, they will drive the locking member 7 to move.

[0041] In this application, a protective element 9 is provided at the inner end of the insertion slot 10 to protect the inner end of the blade 5. Specifically, the protective element 9 includes a rectangular rod 91 inserted into the inner end of the insertion slot 10. The rectangular rod 91 is fixed to the mounting base 1 by bolts 93. A protective plate 92 is fixedly connected to the end of the rectangular rod 91 near the blade 5. The inner surface of the protective plate 92 is flush with the inner wall of the blade groove at the bottom of the mounting plate 31. When using the blade 5, direct contact between the inner end of the blade 5 and the mounting base 1 is avoided. The rectangular rod 91 and the mounting base 1 are detachably connected. When the protective plate 92 is worn, the rectangular rod 91 and the protective plate 92 can be replaced as needed.

[0042] The working principle of this embodiment is as follows: By installing the insert 3 in the insertion slot 10, the insert 3 can be pulled outwards when installing the blade 5, and the blade 5 can be inserted into the blade groove at the bottom of the mounting plate 31. Since there is a magnet in the blade groove, the blade 5 can be initially positioned after insertion. Next, the two guide rods 35 are aligned with the two guide holes 34 respectively, and then the mounting plate 31 is inserted into the insertion slot 10 until the blade 5 contacts the protective plate 92. Then, the two first screws 63 are rotated to move the two first screws 63 towards the insertion slot 10, thereby causing the two pairs of transmission blocks 61 and clamping blocks 62 to move closer together, so that the two clamping blocks 62 abut against the two side walls of the blade 5 respectively, so that the blade 5 completes a stable support connection. Next, rotate the second screw 73 to move it towards the inside of the threaded cylinder 72, thereby pushing the locking rod 71 into the locking hole 51. In this application, multiple locking elements 7 and locking holes 51 are provided, so that each locking rod 71 is inserted into the corresponding locking hole 51 to lock the blade 5 and make the blade 5 have a stable working state.

[0043] The above specific embodiments are merely preferred embodiments of this application. Based on the technical solutions of this application and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments. The above specific embodiments are merely explanations of this application and are not limitations on this application.
