Description

Technical Field

[0001] This application relates to the field of shaper tool fixing technology, and in particular to a shaper tool fixing mechanism. Background Technology

[0002] The shaper is mainly used for precise cutting of various workpieces, especially suitable for machining flat and inclined surfaces. In the actual machining process, through the relative movement between the tool and the workpiece, the cutting edge of the tool is used to remove material from the workpiece, so that the workpiece can achieve the expected shape and size requirements. It is one of the important equipment to ensure the machining quality and precision of mechanical parts.

[0003] In related technologies, the cutting edge of a cutting tool is fixedly connected to the mounting component used to fix the tool, and the two are structurally difficult to separate. When the cutting edge wears down due to long-term use during the machining process and needs to be replaced to ensure machining accuracy and efficiency, the entire cutting tool along with the mounting component associated with the tool must be replaced to complete the cutting edge replacement operation.

[0004] However, when the cutting edge needs to be replaced due to wear or damage, it is not possible to replace the cutting edge or the cutting head of the tool separately. The entire tool must be replaced together with the related components, which not only increases the cost of tool consumables but also prolongs the replacement operation time and further reduces production continuity. Utility Model Content

[0005] To address the aforementioned problems, this application provides a planer fixing mechanism.

[0006] The technical solution for the fixing mechanism of a shaper provided in this application is as follows: A planer fixing mechanism includes a tool holder, a tool mounting block, a cutting tool, and a first abutting bolt. The tool mounting block is slidably disposed on the tool holder in a vertical direction. The tool mounting block is provided with a tool mounting groove. The cutting tool slides and engages with the tool mounting groove. The first abutting bolt is threadedly engaged with the tool mounting block and abuts against the cutting tool.

[0007] By adopting the above technical solution, when the cutting edge needs to be replaced due to wear or damage, there is no need to disassemble the tool mounting block and other related parts on the tool holder. Simply loosen the first abutment bolt to slide the tool out of the tool mounting slot. After replacing the new tool, tighten the first abutment bolt to complete the fixation. This setting realizes independent tool replacement, reduces the need to replace the entire tool and related mounting parts in the traditional method, simplifies the replacement operation process, and improves the continuity of production.

[0008] Preferably, the tool mounting block is provided with a first threaded hole, the first threaded hole penetrates the tool mounting block, and the first abutting bolt is threadedly engaged with the first threaded hole.

[0009] By adopting the above technical solution, the first threaded hole penetrates the tool mounting block, allowing the first abutting bolt to stably enter the tool mounting block through the threaded engagement with the first threaded hole and directly abut against the tool. This ensures that the clamping force of the first abutting bolt on the tool is uniform and reliable, reducing tool displacement due to unstable fixing during processing. It also makes the tightening and loosening of the first abutting bolt more convenient, allowing for quick tool fixing and disassembly, further simplifying the replacement operation process, shortening the replacement time, and improving production continuity.

[0010] Preferably, it also includes a support block, which is fixed on the tool holder. The support block is provided with a sliding groove, and the tool mounting block is slidably disposed in the sliding groove.

[0011] By adopting the above technical solution, the support block is fixed on the tool holder and is provided with a sliding groove. The tool mounting block is slidably set in the sliding groove. With the second abutment bolt, the position of the tool mounting block can be fixed. The height of the tool mounting block itself can be directly adjusted by sliding the tool mounting block in the sliding groove. Also, because the tool is installed in the tool mounting groove, the tool height can be adjusted synchronously with the change of the tool mounting block height. This achieves dual adjustability of the tool mounting block and tool height, which can flexibly adapt to the diverse needs of different processing scenarios for tool height.

[0012] Preferably, the device includes an adjustment assembly comprising a handwheel, a threaded rod, a support base, a sliding base, and a sliding column. The support base is fixedly connected to the side wall of the tool holder, the sliding column is fixedly connected along the vertical direction of the support base, the sliding base is slidably disposed on the sliding column, the threaded rod is rotatably supported by the support base, the threaded rod is threadedly engaged with the sliding base, the handwheel is coaxially fixed with the threaded rod, and the sliding base is fixedly connected to the tool mounting block.

[0013] By adopting the above technical solution, the support base is fixed in the sliding groove. Turning the handwheel can drive the threaded rod to rotate. Through the threaded engagement between the threaded rod and the sliding base, and the sliding base being slidably set on the sliding column, the rotational motion of the threaded rod is converted into the linear movement of the sliding base along the sliding column. The fixed connection between the sliding base and the tool mounting block can synchronously drive the tool mounting block to adjust its position. This not only realizes convenient fine adjustment of the tool mounting block and tool position, but also ensures the stability and reliability of the adjustment process. It can flexibly adapt to the position requirements under different processing conditions, improving processing accuracy and operating efficiency.

[0014] Preferably, it further includes a second abutting bolt, which is threadedly engaged with the support block and abuts against the tool mounting block.

[0015] By adopting the above technical solution, the second abutting bolt is threadedly engaged with the support block and abuts against the tool mounting block. After the tool mounting block is adjusted to the correct position along the sliding groove of the support block by the adjusting component, the tool mounting block can be firmly locked in the current position by tightening the second abutting bolt. At the same time, the vibration and load during processing are mainly borne by the support block and the bolt, reducing the excessive load transmitted to the adjusting component and reducing damage to the adjusting component.

[0016] Preferably, the support block is provided with a second threaded hole, the second threaded hole penetrates the support block, and the second abutting bolt is threadedly engaged with the second threaded hole.

[0017] By adopting the above technical solution, the second threaded hole penetrates the support block, allowing the second abutting bolt to enter the support block and abut against the tool mounting block through threaded engagement with the support block. This ensures that the clamping force of the second abutting bolt on the tool mounting block is stable and uniform, enhances the stability of the tool mounting block after it is fixed, reduces positional deviation caused by processing vibration, and can quickly lock the tool mounting block after adjusting the position of the tool mounting block with the adjustment component.

[0018] Preferably, the tool mounting block is provided with a protrusion, and the tool mounting block slides a certain distance, with the upper surface of the protrusion abutting against the support block.

[0019] By adopting the above technical solution, when the tool block slides along the sliding groove of the support block to a specific position, the raised upper surface abuts against the support block to form a mechanical limit, which can effectively limit the sliding stroke of the tool block and ensure that the position adjustment of the tool block is always within a controllable range.

[0020] Preferably, the edges of the blade mounting block are rounded.

[0021] By adopting the above technical solution, the edges of the tool mounting block are rounded, which can effectively reduce the scratches caused by sharp edges when operators adjust the position of the tool mounting block or change the tool, thus improving operational safety. At the same time, it reduces the local stress concentration when the tool mounting block slides and engages with components such as the support block, reduces the risk of edge damage due to repeated friction or collision, and makes the tool mounting block slide more smoothly.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The tool mounting block slides vertically on the tool holder, and the tool slides into the tool mounting groove and is fixed by the first abutment bolt. When the blade is worn or damaged, there is no need to disassemble the tool mounting block and other parts of the tool holder. Just loosen the first abutment bolt to take out the old tool and replace it with a new tool. Then tighten the bolt to complete the fixation. This realizes independent tool replacement, simplifies the replacement process, and effectively improves production continuity. 2. The support block is fixed to the tool holder and is provided with a sliding groove. The tool mounting block is slidably set in the sliding groove and can be fixed in position by the second abutment bolt. The height of the tool mounting block can be directly adjusted by sliding the tool mounting block in the sliding groove. The tool can also be installed in the tool mounting groove so that the height of the tool can be adjusted synchronously with the height of the tool mounting block. Thus, the height of both the tool mounting block and the tool can be adjusted to flexibly adapt to the diverse needs of different processing scenarios for tool height. 3. Rotating the handwheel drives the threaded rod to rotate. Utilizing the threaded engagement between the threaded rod and the sliding seat, and the sliding restriction of the sliding column on the sliding seat, the rotational motion of the threaded rod is converted into linear movement of the sliding seat along the sliding column. The fixed connection between the sliding seat and the tool mounting block synchronously drives the tool mounting block and the tool to adjust their positions. This achieves convenient fine-tuning of the tool mounting block and tool positions while ensuring a stable and reliable adjustment process. It can flexibly adapt to the positional requirements of different machining conditions, effectively improving machining accuracy and operational efficiency. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a fixing mechanism for a shaper. (Refer to...) Figure 1A planer fixing mechanism includes a tool holder 1, a tool mounting block 2, a cutting tool 3, and a first abutting bolt 4. The tool mounting block 2 is slidably mounted on the tool holder 1 in a vertical direction. The tool mounting block 2 is provided with a tool mounting groove 21. The cutting tool 3 slides and engages with the tool mounting groove 21, allowing the cutting tool 3 to slide within the tool mounting groove 21. The first abutting bolt 4 is threadedly engaged with the tool mounting block 2. The end of the first abutting bolt 4 abuts against the cutting tool 3. By rotating the first abutting bolt 4, the first abutting bolt 4 can be pressed against the cutting tool 3, thereby fixing the cutting tool 3 within the tool mounting groove 21, reducing the shaking of the cutting tool 3 during operation, and ensuring the machining accuracy and stability.

[0030] Furthermore, when the cutting edge needs to be replaced due to wear or damage, there is no need to disassemble the tool mounting block 2 and other related components on the tool holder 1. Simply loosen the first abutting bolt 4 to slide the tool 3 out of the tool mounting slot 21. After replacing the new tool 3, tighten the first abutting bolt 4 to complete the fixation. This setting enables independent replacement of the tool 3, reduces the need to replace the entire tool 3 and related mounting components in the traditional method, simplifies the replacement operation process, shortens the replacement time, and improves the continuity of production.

[0031] Reference Figure 2 and Figure 3 Specifically, the tool mounting block 2 is provided with a tool mounting groove 21 and a first threaded hole 22. The tool mounting groove 21 is used to accommodate the tool 3. The shape and size of the tool mounting groove 21 should be adapted to the tool 3 to ensure that the tool 3 can slide smoothly in the tool mounting groove 21.

[0032] Furthermore, the first threaded hole 22 is located at the lower end of the tool mounting block 2. The first threaded hole 22 penetrates the tool mounting block 2 and is used to engage with the first abutting bolt 4. When the first abutting bolt 4 is rotated, the end of the first abutting bolt 4 will gradually approach the tool 3. Utilizing the locking characteristics of the threaded engagement, it will eventually abut against the tool 3, thereby fixing the tool 3 in the tool mounting groove 21. In addition, the tool 3 is a key component for cutting. The tool 3 is long and has a sharp cutting edge at its end.

[0033] In this embodiment, the combination logic of the tool mounting block 2, the tool 3 and the first abutting bolt 4 is as follows: first, the tool 3 is placed into the tool mounting slot 21, and then the first abutting bolt 4 is rotated to make the first abutting bolt 4 abut against the tool 3, thereby fixing the tool 3. This combination method makes the installation and removal of the tool 3 very convenient. When the blade of the tool 3 is worn, the first abutting bolt 4 can be loosened directly and the tool 3 can be taken out for replacement without replacing the entire tool 3 together with the mounting components.

[0034] Furthermore, it also includes a support block 5, which is fixed on the tool holder 1. The support block 5 is provided with a sliding groove 51, and the tool mounting block 2 is slidably disposed in the sliding groove 51. The shape and size of the sliding groove 51 are adapted to the tool mounting block 2 to ensure that the tool mounting block 2 can slide smoothly in the sliding groove 51.

[0035] Reference Figure 4 Meanwhile, the mechanism also includes an adjustment component 6, which includes a handwheel 61, a threaded rod 62, a support base 63, a sliding base 64, and a sliding column 65. The support base 63 is fixedly connected to the side wall of the tool holder 1. In this embodiment, two sliding columns 65 are provided, and the two sliding columns 65 are fixed on the support base 63 along the vertical direction. The threaded rod 62 is rotatably supported on the support base 63 and is located between the two sliding columns 65. The sliding base 64 is slidably disposed on the sliding column 65, and the threaded rod 62 and the sliding base 64 are threadedly engaged. The handwheel 61 is coaxially fixed with the threaded rod 62, and the sliding base 64 is fixedly connected to the tool mounting block 2. By rotating the handwheel 61, the threaded rod 62 can be rotated, thereby causing the sliding base 64 to slide on the sliding column 65, thereby driving the tool mounting block 2 to adjust its vertical position on the tool holder 1.

[0036] This demonstrates that the support block 5 provides a stable sliding platform for the tool holder 2. The sliding of the tool holder 2 within the sliding groove 51 is restricted and guided by the support block 5, thus ensuring the accuracy and stability of the vertical sliding of the tool holder 2 on the tool holder 1. Simultaneously, by rotating the handwheel 61, the threaded rod 62 is driven to rotate. Since the threaded rod 62 is threadedly engaged with the sliding seat 64, the rotation of the threaded rod 62 is converted into the linear movement of the sliding seat 64 along the sliding column 65. Since the sliding seat 64 is fixedly connected to the tool holder 2, the tool holder 2 will adjust its vertical position within the sliding groove 51 as the sliding seat 64 moves. This achieves convenient fine-tuning of the positions of the tool holder 2 and the tool 3, while ensuring the stability and reliability of the adjustment process. It can flexibly adapt to the position requirements under different machining conditions, improving machining accuracy and operating efficiency.

[0037] Specifically, it also includes a second abutment bolt 7. The support block 5 is provided with a second threaded hole 52, which passes through the support block 5. The second abutment bolt 7 is threadedly engaged with the second threaded hole 52. The function of the second abutment bolt 7 is to further fix the position of the tool holder 2 and reduce the shaking of the tool holder 2 during operation. After the tool holder 2 is adjusted to a suitable position by the adjusting component 6, the second abutment bolt 7 is rotated so that the end of the second abutment bolt abuts against the tool holder 2, thereby firmly fixing the tool holder 2 on the support block 5. At the same time, the vibration and load during processing are mainly borne by the support block 5 and the bolt, reducing the excessive load transmitted to the adjusting component 6 and reducing damage to the adjusting component 6.

[0038] In addition, the tool mounting block 2 is provided with a protrusion 23. When the tool mounting block 2 slides a certain distance, the upper surface of the protrusion 23 abuts against the support block 5. The protrusion 23 and the tool mounting block 2 are integrally formed. The function of the protrusion 23 is to limit the sliding stroke of the tool mounting block 2. When the tool mounting block 2 slides to a certain position, the upper surface of the protrusion 23 will abut against the support block 5. At this time, the tool mounting block 2 can no longer slide upward, ensuring that the position adjustment of the tool mounting block 2 is always within the controllable range.

[0039] In addition, the edge of the tool mounting block 2 is rounded 24. The rounded corners 24 can effectively reduce the scratches caused by sharp edges when the operator adjusts the position of the tool mounting block 2 or replaces the tool 3, thus improving the safety of operation. At the same time, it reduces the local stress concentration when the tool mounting block 2 slides and engages with the support block 5 and other components, reduces the risk of damage to the edge due to repeated friction or collision, and makes the tool mounting block 2 slide more smoothly.

[0040] The implementation principle of a planer fixing mechanism in this application embodiment is as follows: The cutting tool 3 is slidably inserted into the tool mounting slot 21. The first abutting bolt 4 is rotated to tighten the cutting tool 3 and fix it. Then, the tool mounting block 2 is slidably inserted into the sliding slot 51 of the support block 5. The handwheel 61 is rotated to adjust the tool mounting block 2 vertically to a suitable position through the adjustment component 6. After the position is determined, the second abutting bolt 7 is rotated to pass through the second threaded hole 52 of the support block 5 and tighten the tool mounting block 2, further fixing the position of the tool mounting block 2. If the cutting tool 3 is worn during processing, the first abutting bolt 4 can be loosened to remove the old cutting tool 3 and replace it with a new cutting tool 3 without disassembling other parts, realizing the quick replacement of the cutting tool 3 and the adjustment of the cutting tool 3 and the tool mounting block 2.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
