[0013] According to the above technical solution, the worktable surface is also provided with a clamping device for strengthening the planer blade and a scraping device for cleaning the friction wheel surface. The clamping device includes a push rod, a key, a push rod, and a sliding plate. The push rod is fixedly installed on the side of the rotating rod away from the telescopic table. The key is slidably installed on the inner wall of the sliding frame. The sliding table has a slot on the side near the key, and the slot's shape matches the key. The push rod is slidably installed on the outer wall of the sliding table. The sliding plate is slidably installed at the bottom of the telescopic table. The key locks the telescopic table to prevent the tool from springing back or vibrating during planing, ensuring that the planer blade maintains a constant cutting depth and avoiding unevenness of the machined surface caused by uneven force. The sliding plate clamps the planer blade, enhances the tool rigidity, and reduces cutting vibration, making it especially suitable for hardwood or high-precision planing, and improving surface finish.

[0014] According to the above technical solution, the clamping device further includes a fixing key, a pressing plate, a connecting rod, a sliding rod, a pressure rod, and a pressure plate. The fixing key is slidably installed on the inner wall of the telescopic table. A fixing groove is formed on the side of the planer blade near the fixing key, and the fixing key contacts the inner wall of the fixing groove. The pressing plate is slidably installed on the side of the telescopic table near the fixing key. The sliding rod is slidably installed on the side of the telescopic table near the fixing key. A square groove is formed on the side of the fixing key near the sliding rod. One end of the connecting rod is rotatably installed on the side of the pressing plate near the sliding rod, and the other end of the connecting rod is rotatably installed on the side of the sliding rod near the pressing plate. The pressure rod is slidably installed on the side of the telescopic table near the fixing key, and the pressure plate is slidably installed on the inner wall of the telescopic table. By simply pushing the pressure rod, the fixing key can automatically exit the fixing groove of the planer blade through the linkage of the connecting rod and the sliding rod. No tools are required, which greatly shortens the tool changing time. It is suitable for frequent tool changing scenarios, reduces equipment downtime, and improves production efficiency.

[0015] According to the above technical solution, the side of the push rod and the key that are close to each other is set as an inclined surface. The inclined surface of the push rod and the key is to facilitate the push rod to push the key to move away from the telescopic table. A No. 3 spring is provided between the key and the sliding table. The No. 3 spring is provided to drive the key to move towards the inner wall of the sliding table. A No. 4 spring is provided between the sliding plate and the telescopic table. The No. 4 spring is provided to drive the sliding plate to reset.

The slide rod is rotatably mounted on the side of the second rack near the scraper. A slide rail is provided on the side of the scraper near the slide rod. The slide rod is slidably mounted on the inner wall of the slide rail. The scraper automatically engages with the friction wheel, removing residual wood chips and resin from the wheel surface during the resetting process. This prevents dirt accumulation from affecting subsequent sanding results, ensuring consistent surface smoothness of the wood board after each planing operation. Timely cleaning of residues on the friction wheel surface reduces wear from particles, prevents unevenness caused by hardened dirt, and extends the friction wheel replacement cycle.

[0017] According to the above technical solution, the scraping device further includes a collection frame, a connecting rod, a fixing block, and a cover plate. The collection frame is fixedly installed at the bottom of the scraper, the cover plate is slidably installed inside the scraper, the fixing block is fixedly installed on the side of the cover plate near the sliding rod, one end of the connecting rod is fixedly installed on the side of the sliding rod near the fixing block, and the other end of the connecting rod is fixedly installed on the side of the fixing block near the sliding rod. The debris scraped off by the scraper directly enters the collection frame, preventing sawdust, resin, and other residues from scattering, maintaining the cleanliness of the processing area, and reducing the amount of subsequent cleaning work. The cover plate automatically seals the collection trough to prevent the collected debris from spilling when the equipment moves or vibrates, ensuring centralized treatment of sawdust and meeting environmental protection requirements.

[0018] According to the above technical solution, a collection groove is provided on the surface of the scraper, the collection groove is connected to the collection frame, and the shape of the cover plate matches the collection groove.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. In this invention, the upward movement of the telescopic table will drive the planer and friction wheel to move upward. When the sliding table is reset, the planer and friction wheel will not contact the surface of the wooden board, thus avoiding the planer and friction wheel from scraping the processed surface again during the reset process, preventing scratches or secondary damage to the surface of the wooden board, improving processing accuracy and surface finish. Automatic tool lifting is achieved through inclined surface contact and spring storage, reducing manual adjustment steps and improving continuous processing efficiency.

[0021] 2. In this invention, when the wooden board is planed for the second time, the sliding key will not block the sliding frame. The storage spring will push the telescopic table to descend a greater distance, so that the planer can feed deeper. The first planing uses a shallower feed to reduce cutting resistance and avoid deformation of the wooden board or tool jamming. The depth of subsequent planing is gradually increased, which improves cutting efficiency while ensuring processing quality. It is especially suitable for hardwood or workpieces with high precision requirements.

[0022] 3. In this invention, the sliding plate moves to fit against the planer and clamp the planer. The key locks the telescopic table to prevent the tool from springing back or vibrating during planing, ensuring that the planer maintains a constant cutting depth and avoiding unevenness of the machined surface caused by uneven force. The sliding plate clamps the planer, enhances the rigidity of the tool, and reduces cutting vibration. It is especially suitable for hardwood or high-precision planing and improves surface finish.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-7 One embodiment of the present invention is: an adjustable feed planer for precision instruments, comprising a worktable 1, a clamping plate 2 slidably mounted on the inner wall of the worktable 1, a slide rail 3 fixedly mounted on the surface of the worktable 1, a sliding table 4 slidably mounted on the outer wall of the slide rail 3, a telescopic table 5 slidably mounted on the inner wall of the sliding table 4, a storage spring provided between the telescopic table 5 and the sliding table 4, a planing blade 6 fixedly mounted on the bottom of the telescopic table 5, a friction wheel 7 fixedly mounted on the bottom of the sliding table 4, and an adjustment device provided on the surface of the sliding table 4.

[0034] The clamp 2 is provided to secure the wood board being cut.

[0035] The planer blade 6 is provided for cutting the surface of the wood board.

[0036] The friction wheel 7 is provided to polish the surface of the cut wooden board.

[0037] The adjustment device also includes a sliding key 13 and a sliding pin 14. The sliding key 13 is slidably installed on the outer wall of the sliding table 4 near the sliding frame 8. The sliding frame 8 has a slot on the side near the sliding key 13, and the shape of the slot matches the sliding key 13. The sliding pin 14 is slidably installed on the outer wall of the sliding table 4. The sliding key 13 has a square groove on the side near the sliding pin 14, and the shape of the square groove matches the sliding pin 14. The first planing uses a shallow feed rate to reduce cutting resistance and avoid wood deformation or tool jamming. Subsequent planing gradually increases the depth, improving cutting efficiency while ensuring processing quality. It is especially suitable for hardwood or workpieces with high precision requirements.

[0038] The adjustment device includes a sliding frame 8, a rotating rod 9, a fixed plate 10, a fixed platform 11, and rollers 12. The outer wall of the sliding platform 4 has a groove. The sliding frame 8 is fixedly installed on the outer wall of the telescopic platform 5 and contacts the inside of the groove. The rotating rod 9 is rotatably installed on the inner wall of the sliding frame 8. The rollers 12 are rotatably installed inside the rotating rod 9. The fixed plate 10 is fixedly installed on the side of the sliding frame 8 near the planer 6. The fixed platform 11 is fixedly installed on the surface of the worktable 1. This prevents the planer 6 and the friction wheel 7 from scraping the processed surface again during the reset process, preventing scratches or secondary damage to the wood surface, improving processing accuracy and surface finish. Automatic tool lifting is achieved through inclined contact and spring storage, reducing manual adjustment steps and improving continuous processing efficiency.

[0039] The fixed platform 11 has inclined surfaces on the side near the roller 12 and the side away from the roller 12. The inclined surfaces of the fixed platform 11 are designed to facilitate the movement of the roller 12 along the surface of the fixed platform 11. The top and bottom of the sliding key 13 near the sliding frame 8 have inclined surfaces. The inclined surfaces of the sliding key 13 are designed to facilitate the sliding frame 8 to push the sliding key 13 to move. The length of the bottom inclined surface is greater than the length of the top inclined surface. A first spring is provided between the sliding key 13 and the sliding platform 4. The first spring is provided to push the sliding key 13 toward the inner wall of the slot. A second spring is provided between the sliding pin 14 and the sliding platform 4. The second spring is provided to drive the sliding pin 14 toward the inner wall of the square groove.

[0040] In this embodiment, during operation: when planing the surface of a wooden board, the board must first be placed on the surface of the workbench 1. After placement, the clamping plate 2 will activate to fix the board. After the board is fixed, the sliding table 4 will drive the telescopic table 5 to move. The movement of the telescopic table 5 will drive the planer 6 and friction wheel 7 to move. When the planing of the board is completed and the board is reset, the sliding table 4 will drive the sliding frame 8 to move. The movement of the sliding frame 8 will drive the rotating rod 9 to move. The movement of the rotating rod 9 will drive the roller 12 to move. When the roller 12 moves, it will contact the inclined surface of the fixed table 11, and the rotating rod 9 will rotate away from the fixed table 11. When the rotating rod 9 rotates, it will contact the fixed plate 10, and the fixed plate 10 will limit the rotating rod 9, preventing the rotating rod 9 from moving away from the fixed table 11. If the rotating rod 9 cannot rotate when rotated away from the fixed table 11, the roller 12 will move along the surface of the fixed table 11. When the roller 12 contacts the top of the fixed table 11, the rotating rod 9 will push the sliding frame 8 upward. The upward movement of the sliding frame 8 will drive the telescopic table 5 upward. The upward movement of the telescopic table 5 will drive the planer 6 and friction wheel 7 upward. Therefore, when the sliding table 4 is reset, the planer 6 and friction wheel 7 will not contact the surface of the wood board, avoiding the planer 6 and friction wheel 7 from scraping the processed surface again during the reset process, preventing scratches or secondary damage to the surface of the wood board, improving processing accuracy and surface finish. Automatic tool lifting is achieved through inclined contact and spring storage, reducing manual adjustment steps and improving continuous processing efficiency. When planing the wood, the storage spring pushes the telescopic table 5 downwards. This downward movement of the telescopic table 5 causes the planer blade 6 and friction wheel 7 to move downwards, bringing the planer blade 6 to a position slightly below the surface of the wood. As the telescopic table 5 moves downwards, it causes the sliding frame 8 to move. The sliding frame 8 then contacts the inclined surface at the top of the sliding key 13, pushing the sliding key 13 away from the sliding frame 8. When the sliding key 13 aligns with the slot, the first spring causes the sliding key 13 to insert into the slot, limiting the sliding frame 8 and preventing the storage spring from pushing the telescopic table 5 further downwards. When the sliding table 4 returns to its original position, the sliding frame 8 moves upwards, contacting the inclined surface at the bottom of the sliding key 13. If the sliding key 13 pushes the sliding frame 8 towards the sliding pin 14, the movement of the sliding key 13 will cause the square groove to move. When the position of the square groove coincides with the sliding pin 14, the sliding pin 14 will be driven by the second spring to move into the square groove. Then the sliding key 13 will be limited by the sliding pin 14. Therefore, when the wood is planed for the second time, the sliding key 13 will not block the sliding frame 8. The storage spring will push the telescopic table 5 to descend a greater distance, so that the cutting tool 6 can cut deeper. The first planing uses a shallower cutting depth to reduce cutting resistance and avoid wood deformation or tool jamming. Subsequent planing gradually increases the depth, which improves cutting efficiency while ensuring processing quality. It is especially suitable for hardwood or workpieces with high precision requirements.

[0041] Please see Figures 1-7In another embodiment of the present invention, based on the above embodiments, the worktable 1 surface is further provided with a clamping device for strengthening the planer 6 and a scraping device for cleaning the surface of the friction wheel 7. The clamping device includes a push rod 21, a key 22, a push rod 23 and a sliding plate 24. The push rod 21 is fixedly installed on the side of the rotating rod 9 away from the telescopic table 5. The key 22 is slidably installed on the inner wall of the sliding frame 8. The sliding table 4 has a slot on the side near the key 22, and the shape of the slot matches the key 22. The push rod 23 is slidably installed on the outer wall of the sliding table 4. The sliding plate 24 is slidably installed on the bottom of the telescopic table 5. The key 22 locks the telescopic table 5 to prevent the tool from springing back or vibrating during planing, ensuring that the planer 6 maintains a constant cutting depth and avoiding unevenness of the machined surface caused by uneven force. The sliding plate 24 clamps the planer 6, enhances the rigidity of the tool, reduces cutting vibration, and is especially suitable for planing hardwood or high-precision wood, improving surface finish.

[0042] The clamping device also includes a fixing key 25, a pressing plate 26, a connecting rod 27, a sliding rod 28, a pressure rod 29, and a pressure plate 291. The fixing key 25 is slidably installed on the inner wall of the telescopic table 5. A fixing groove is provided on the side of the planer 6 near the fixing key 25, and the fixing key 25 contacts the inner wall of the fixing groove. The pressing plate 26 is slidably installed on the side of the telescopic table 5 near the fixing key 25. The sliding rod 28 is slidably installed on the side of the telescopic table 5 near the fixing key 25, and a square groove is provided on the side of the fixing key 25 near the sliding rod 28. One end of the connecting rod 27 is rotatably mounted. The connecting rod 27 is mounted on the side of the push plate 26 near the sliding rod 28, and the other end of the connecting rod 27 is rotatably mounted on the side of the sliding rod 28 near the push plate 26. The pressure rod 29 is slidably mounted on the side of the telescopic table 5 near the fixed key 25, and the pressure plate 291 is slidably mounted on the inner wall of the telescopic table 5. By simply pushing the pressure rod 29, the fixed key 25 can be automatically disengaged from the fixed slot of the planer 6 through the linkage of the connecting rod 27 and the sliding rod 28. No tools are required, which greatly shortens the tool changing time. It is suitable for frequent tool changing scenarios, reduces equipment downtime, and improves production efficiency.

[0043] The side of the push rod 21 and the key 22 that are close to each other is set as an inclined surface. The inclined surface of the push rod 21 and the key 22 is to facilitate the push rod 21 to push the key 22 to move away from the telescopic table 5. A No. 3 spring is provided between the key 22 and the sliding table 4. The No. 3 spring is provided to drive the key 22 to move towards the inner wall of the sliding table 4. A No. 4 spring is provided between the sliding plate 24 and the telescopic table 5. The No. 4 spring is provided to drive the sliding plate 24 to reset. A No. 5 spring is provided between the button plate 26 and the telescopic table 5. The No. 5 spring is provided to drive the button plate 26 to reset. A No. 6 spring is provided between the pressure plate 291 and the telescopic table 5. The No. 6 spring is provided to drive the pressure plate 291 to reset. The side of the sliding rod 28 that is close to the fixed key 25 is set as an inclined surface.

[0044] The scraping device includes a first rack 31, a gear 32, a second rack 33, a scraper 34, and a slide bar 35. The gear 32 is rotatably mounted on the outer wall of the sliding table 4. The first rack 31 is fixedly mounted on the side of the sliding plate 24 near the gear 32. The second rack 33 is slidably mounted on the side of the sliding table 4 near the gear 32. The scraper 34 is rotatably mounted on the bottom of the sliding table 4. The slide bar 35 is rotatably mounted on the side of the second rack 33 near the scraper 34. A slide rail is provided on the side of the scraper 34 near the slide bar 35. The slide bar 35 is slidably mounted on the inner wall of the slide rail. The scraper 34 automatically engages with the friction wheel 7, removing residual wood chips and resin from the wheel surface during the resetting process. This prevents the accumulation of dirt from affecting the subsequent sanding effect, ensuring a consistent surface finish of the wood board after each planing operation. Timely cleaning of residues on the surface of the friction wheel 7 reduces wear on the wheel surface caused by particles, prevents unevenness of the wheel surface due to hardened dirt, and extends the replacement cycle of the friction wheel.

[0045] The scraping device also includes a collection frame 36, a connecting rod 37, a fixing block 38, and a cover plate 39. The collection frame 36 is fixedly installed at the bottom of the scraper 34, and the cover plate 39 is slidably installed inside the scraper 34. The fixing block 38 is fixedly installed on the side of the cover plate 39 near the slide rod 35. One end of the connecting rod 37 is fixedly installed on the side of the slide rod 35 near the fixing block 38, and the other end of the connecting rod 37 is fixedly installed on the side of the fixing block 38 near the slide rod 35. The debris scraped off by the scraper 34 directly enters the collection frame 36, preventing sawdust, resin, and other residues from scattering, maintaining the cleanliness of the processing area, and reducing the amount of subsequent cleaning work. The cover plate 39 automatically seals the collection trough to prevent the collected debris from spilling when the equipment moves or vibrates, ensuring centralized treatment of sawdust and meeting environmental protection requirements.

[0046] The scraper 34 has a collection groove on its surface, which is connected to the collection frame 36. The cover plate 39 is shaped to match the collection groove.

[0047] In this embodiment, during operation: when the sliding table 4 moves the planer 6 to plan the wood, it moves the sliding frame 8. The movement of the sliding frame 8 moves the rotating rod 9. The rotating rod 9 contacts the fixed table 11 and rotates away from the fixed table 11. The rotation of the rotating rod 9 drives the push rod 21 to rotate. The rotation of the push rod 21 releases the obstruction of the key 22, and the key 22 is driven by the third spring to move into the socket. When the key 22 contacts the inner wall of the socket, it limits the telescopic table 5, preventing the planer 6 from moving away from the wood when the telescopic table 5 is planing the wood. The rotation of the push rod 21 contacts the push rod 23, which pushes the push rod 23 away from the sliding frame 8. The movement of the push rod 23 pushes the sliding plate 24 to move. The sliding plate 24 engages with the planer 6 and locks the planer 6 in place. The key 22 locks the telescopic table 5, preventing the tool from rebounding or vibrating during planing, ensuring that the planer 6 maintains a constant cutting depth, and avoiding... Uneven machining surfaces caused by uneven force are addressed by sliding plate 24 clamping the planer 6, enhancing tool rigidity, reducing cutting vibration, and making it particularly suitable for hardwood or high-precision planing, thus improving surface finish. When the planer 6 needs to be replaced, push the pressure rod 29 to move. The movement of pressure rod 29 will push the pressure plate 291 to move, which in turn will push the pressing plate 26 downward. The downward movement of pressing plate 26 will push the connecting rod 27 to move, which will then push the sliding rod 28 towards the fixed key 25. The inclined surface of the sliding rod 28 will then contact the square groove, causing the fixed key 25 to move away from the planer 6. Pushing the pressure rod 29 can quickly release the limit between the planer 6 and the telescopic table 5. Simply pushing the pressure rod 29 will automatically disengage the fixed key 25 from the fixed groove of the planer 6 through the linkage of the connecting rod 27 and the sliding rod 28, eliminating the need for tools, significantly shortening tool change time, and making it suitable for frequent tool change scenarios, reducing equipment downtime and improving production efficiency.

[0048] When the sliding table 4 resets, the push rod 21 releases the thrust on the push rod 23. The sliding plate 24, driven by the fourth spring, moves away from the planer blade 6. This movement causes the first rack 31 to move, which in turn rotates the gear 32. The gear 32 then moves the second rack 33 towards the friction wheel 7. This movement causes the slide rod 35 to move, which in turn rotates the scraper 34 towards the friction wheel 7, bringing it into contact with the surface of the friction wheel 7. The scraper 34 automatically adheres to the friction wheel 7, removing residual sawdust and resin during the reset process. This prevents dirt accumulation from affecting subsequent sanding, ensuring a consistent surface finish after each planing operation. Timely cleaning of residue on the friction wheel 7 reduces wear from particles, prevents unevenness due to hardened dirt, and extends the friction wheel replacement cycle. The movement of the scraper 34 also moves the collection frame 36. The scraped debris from scraper 34 enters the inner wall of collection frame 36 through the collection trough. When sliding plate 24 moves towards planer 6, it drives rack 31 to move. The movement of rack 31 drives gear 32 to rotate. The rotation of gear 32 drives rack 33 to move. The movement of rack 33 drives slide rod 35 to move. The movement of slide rod 35 pushes scraper 34 to rotate back to its original position. When slide rod 35 pushes scraper 34 to rotate back to its original position, slide rod 35 slides towards cover plate 39. The movement of slide rod 35 pushes connecting rod 37 to move. The movement of connecting rod 37 pushes fixing block 38 to move. The movement of fixing block 38 pushes cover plate 39 to move and seal collection trough. The scraped debris from scraper 34 directly enters collection frame 36, preventing sawdust, resin and other residues from scattering, maintaining the cleanliness of the processing area and reducing the amount of cleaning work later. Cover plate 39 automatically seals collection trough to prevent collected debris from spilling when the equipment moves or vibrates, ensuring centralized treatment of sawdust and meeting environmental protection requirements.
