Description

Technical Field

[0001] This utility model relates to the field of grooving cutter products, specifically a grooving cutter with a quick-installation cutter holder. Background Technology

[0002] A grooving cutter is a cutting tool used to machine protruding grooves and recesses, commonly used in metalworking, woodworking, and plastics processing. Grooving cutters are typically made of carbide and are capable of rapid cutting of workpieces at high speeds. They are frequently used in the manufacture of automotive parts, machine parts, tools, and other industrial products.

[0003] However, the installation of the tool holder and tool shank on the existing grooving tool is quite complicated, and the tool holder cannot be quickly assembled. The installation is time-consuming and laborious. Utility Model Content

[0004] The purpose of this invention is to provide a slotted tool for quick installation of a tool holder, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slotted knife with a quick-installation tool holder, comprising a handle and a tool holder. The handle has a slot, and the tool holder is inserted into the slot. Both sides of the inner wall of the slot have receiving grooves, and each receiving groove contains a locking block. The side wall of the tool holder has a locking groove corresponding to the locking block. The locking block has a beveled section, and one end of the locking block has an arc-shaped groove. The handle has a through hole communicating with the receiving groove. A traction rod is inserted into the through hole. One end of the traction rod is fixedly connected to the locking block, and both sides of the other end of the traction rod are fixedly connected to connecting blocks. A swing rod is rotatably connected to the connecting blocks, and one end of the swing rod is rotatably connected to a slider. Both sides of the handle have a pair of sliding grooves, and a sliding rod is fixedly connected to each sliding groove. The slider is slidably sleeved on the sliding rod, and a spring is sleeved on the sliding rod. Both ends of the spring are fixedly connected to the slider and the inner wall of the sliding groove, respectively.

[0006] Preferably, a magnetic block is fixedly connected to the inner wall of one end of the slot, and one end of the blade bar is attracted and fixed to the magnetic block.

[0007] Preferably, the beveled section on the card block is polished.

[0008] Preferably, both ends of the swing arm are hinged to the slider and the connecting block via pivot pins.

[0009] Preferably, a pair of grooves are respectively provided on both sides of the traction rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This quick-installation tool holder uses a slotted tool holder to install the tool. During installation, the tool holder is inserted into a slot on the tool holder. During insertion, one end of the tool holder presses against the beveled surface of the locking block, moving from the narrow side to the wide side. Simultaneously, the locking block is housed in the tool receiving slot. At this time, the traction rod moves, driving the swing rod. The swing rod then pulls the slider along the sliding rod, compressing the spring. After the tool holder is fully inserted, the locking block aligns with the slot. The spring's rebound force, now in a compressed state, securely engages the locking block in the slot, thus fixing the tool holder. This invention uses a snap-fit ​​fixing component to easily install and fix the tool holder to the tool holder, offering simple and convenient operation. Attached Figure Description

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please see Figure 1-3 This utility model provides an embodiment of a slotted knife with a quick-installation tool holder 2, comprising a tool holder 1 and a tool holder 2. The tool holder 1 has a slot 3, and the tool holder 2 is inserted into the slot 3. The inner walls of both sides of the slot 3 have receiving grooves 4, and each receiving groove 4 contains a locking block 5. The side wall of the tool holder 2 has a locking groove 6 corresponding to the locking block 5. The locking block 5 has a beveled section 7, and one end of the locking block 5 has an arc-shaped groove 8. The tool holder 1 has a through hole 9 communicating with the receiving groove 4, and a traction rod 10 is inserted into the through hole 9. One end of the traction rod 10 is fixedly connected to the locking block 5, and the other end of the traction rod 10 has connecting blocks 11 fixedly connected to both sides. A swing rod 12 is rotatably connected to the connecting block 11, and one end of the swing rod 12 is rotatably connected to a slider 13. Both sides of the tool holder 1 have a pair of sliding grooves 14. A slide rod 15 is fixedly connected inside the slide groove 14. The slider 13 is slidably sleeved on the slide rod 15. A spring 16 is sleeved on the slide rod 15. The two ends of the spring 16 are fixedly connected to the slider 13 and the inner wall of the slide groove 14, respectively. Specifically, the tool bar 2 is inserted into the slot 3 on the tool holder 1. During the insertion process, one end of the tool bar 2 will press against the inclined section 7 of the locking block 5 and move from the narrow side to the wide side of the locking block 5. At the same time, the locking block 5 is housed in the tool receiving slot 4. At this time, the traction rod 10 will move, thereby driving the swing rod 12 to move. The swing rod 12 will then pull the slider 13 to slide on the slide rod 15 and compress the spring 16. After the tool bar 2 is fully inserted, the locking block 5 and the slot 6 are aligned. At this time, the spring 16 in the compressed state has a rebound force that causes the locking block 5 to be firmly locked in the slot 6, thus fixing the tool bar 2.

[0020] In this embodiment, a magnetic block 17 is fixedly connected to the inner wall of one end of the slot 3, and one end of the knife bar 2 is attracted and fixed to the magnetic block 17 to attract and fix the knife bar 2; the inclined section 7 on the card block 5 is polished to reduce the frictional resistance when pressing; both ends of the swing rod 12 are hinged to the slider 13 and the connecting block 11 through the shaft pin; a pair of sliding grooves 14 are respectively provided on both sides of the traction rod 10.

[0021] The working principle of this quick-installation tool holder 2 is described in detail below: First, the tool holder 2 is used to install the tool. When installing the tool holder 1, the tool holder 2 is inserted into the slot 3 on the tool holder 1. During the insertion process, one end of the tool holder 2 will press against the inclined section 7 of the locking block 5, moving from the narrow side to the wide side of the locking block 5. At the same time, the locking block 5 is housed in the tool receiving slot 4. At this time, the traction rod 10 will move, thereby driving the swing rod 12 to move. The swing rod 12 will then pull the slider 13 to slide on the slide rod 15, thereby compressing the spring 16. After the tool holder 2 is fully inserted, the locking block 5 and the slot 6 are aligned. At this time, the spring 16 in the compressed state has a rebound force that causes the locking block 5 to be firmly locked in the slot 6, thus fixing the tool holder 2.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
