Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, and in particular to a tooling for detecting a cutter shaft. Background Technology

[0002] In wood processing, engineered wood production, and some metal processing fields, the performance of a spiral planer directly affects processing quality and production efficiency. Cutting circle accuracy is its core indicator. The cutting circle refers to the virtual circular trajectory formed by the endpoints of all the cutting edges of all the blades on the spiral planer shaft as the shaft rotates at high speed. Each blade has a radial distance relative to the center of the planer shaft. When the shaft rotates, these blades move in a circle around the axis, and the collection of their motion trajectories constitutes the cutting circle, which directly reflects the consistency of the blades' radial position after installation.

[0003] When the circular runout exceeds 0.003mm, the cutting trajectory of the blade deviates from the ideal circle, leading to defects such as ripples and unevenness on the machined surface, thus reducing product surface quality. Simultaneously, uneven cutting forces exacerbate blade wear and cause planer shaft vibration, affecting equipment stability and lifespan. If substandard blades cannot be detected and replaced in a timely manner, the rate of defective products will increase, requiring rework or scrapping, consuming more raw materials, raising production costs, and reducing enterprise efficiency and competitiveness.

[0035] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0036] See Figures 1 to 3 This utility model discloses a tooling fixture for detecting a cutter shaft, which includes a base 10, a cutter shaft assembly 20, and a detection component 30. Specifically, the cutter shaft assembly 20 includes a mounting shaft 21 and cutting blades 22. The mounting shaft 21 is rotatably connected to the base 10. Multiple cutting blades 22 are detachably mounted on the mounting shaft 21, and the multiple cutting blades 22 are arranged in a spiral pattern along the axial direction of the mounting shaft 21. The detection component 30 includes a detection element 31, which is slidably mounted on the base 10. The detection element 31 is used to move along the axial direction of the mounting shaft 21 when the mounting shaft 21 rotates, and to detect the cutting edges of the multiple cutting blades 22.

[0037] Based on this structure, when using the tool shaft inspection fixture of this utility model to inspect the cutting edge of the blade 22, the inspection component 31 can be pushed so that it slides along the base 10 to one end of the mounting shaft 21, and then the inspection component 31 is brought close to the initial inspection position corresponding to the blade 22 on the mounting shaft 21. Next, the rotation device of the mounting shaft 21 is started, so that the mounting shaft 21 drives the blade 22 to rotate together. It should be noted that when the tool shaft is in the working state of planing wood, the mounting shaft 21 drives the blade 22 to rotate in the positive direction (for example, clockwise), then when the inspection component 31 is inspecting the tool shaft, the mounting shaft 21 drives the blade 22 to rotate in the opposite direction (correspondingly, counterclockwise). At this time, the inspection component 31 is pushed so that it moves slowly along the axial direction of the mounting shaft 21 while the mounting shaft 21 is rotating.

[0038] Specifically, when the mounting shaft 21 rotates at high speed, the cutting edges of all the blades 22 on the mounting shaft 21 form a virtual circular trajectory, which is defined as the cutting circle 23. Each blade 22 has a radial distance relative to the center of the mounting shaft 21. When the mounting shaft 21 rotates, these blades move in a circle around the axis, and the collection of their motion trajectories constitutes the cutting circle 23.

[0039] During one revolution of the mounting shaft 21, the maximum and minimum readings of the detection element 31 at the same blade 22 position are recorded. The difference between the two readings is the circular runout of the cutting circle 23 of the blade 22 at that position. If the difference is greater than 0.003 mm, the blade 22 is marked as a replacement. During the movement of the detection element 31, the detection element 31 continuously detects the position of the cutting edges of multiple blades 22, records the radial distance of each cutting edge relative to the center of the mounting shaft 21, and repeats the above operation of rotating the mounting shaft 21 and reading the maximum and minimum differences on the detection element 31 for the cutting circle 23 position of each blade 22. The circular runout of the cutting circle 23 of all blades 22 is detected point by point along the entire length, and all blades 22 with a circular runout greater than 0.003 mm are marked.

[0040] After the inspection piece 31 has completed the inspection of all the cutting edges of the inserts 22, the rotation of the mounting shaft 21 and the movement of the inspection piece 31 are stopped. Based on the data recorded in the inspection record, it is determined which cutting edges of the inserts 22 do not meet the requirements, i.e., their circular runout is greater than 0.003mm. Subsequently, these unqualified inserts 22 are removed from the mounting shaft 21, replaced with new inserts 22, and the above inspection process is repeated until the cutting edges of all inserts 22 meet the accuracy requirements of the cutting circle 23.

[0041] In this way, the detection component 31 moves along the axial direction of the mounting shaft 21 when the mounting shaft 21 rotates, which can comprehensively and continuously detect the multiple spirally arranged cutting edges of the blades 22, accurately capture whether the movement trajectory of each cutting edge is on the ideal cutting circle 23, thereby judging whether the installation accuracy of the blades 22 meets the standard, and providing a reliable basis for screening out unqualified blades 22.

[0042] Therefore, by using the tool shaft detection fixture of this utility model, the blades 22 with excessive circular runout can be detected and replaced in a timely manner, ensuring that the cutting circle 23 formed by the cutting edges of all blades 22 finally installed on the mounting shaft 21 meets the accuracy standard, avoiding defects such as ripples and unevenness on the machined surface due to blade 22 problems, ensuring the surface quality and dimensional accuracy of the machined products, and thus improving the processing quality of the woodworking planer.

[0043] It should be noted that since the multiple blades 22 are arranged in a spiral pattern along the axial direction of the mounting shaft 21, if the detection element 31 is simply pushed to slide along one end of the base 10 to the other end of the mounting shaft 21, the detection element 31 cannot detect the position of the cutting edge of each blade 22. Therefore, it is necessary to coordinate with the rotation of the mounting shaft 21. Through the coordination of the rotation of the mounting shaft 21 and the axial movement of the detection element 31, the detection element 31 can adapt to the spiral arrangement of the blades 22, fully cover the detection point of each cutting edge, accurately capture whether the movement trajectory of each cutting edge conforms to the ideal cutting circle 23 standard, and provide accurate data support for screening unqualified blades 22.

[0044] As an optional implementation, the base 10 is provided with a first mounting seat 11 and a second mounting seat 12. Specifically, the first mounting seat 11 and the second mounting seat 12 are arranged opposite to each other along the axial direction of the mounting shaft 21, and the first mounting seat 11 is fixedly mounted on the base 10, while the second mounting seat 12 is slidably mounted on the base 10 via a first slide block 19. One end of the mounting shaft 21 is rotatably connected to the first mounting seat 11, and the other end of the mounting shaft 21 is rotatably connected to the second mounting seat 12.

[0045] Based on this structure, during assembly, the first mounting base 11 is first fixed to the base 10. Then, the first slide block 19 is slid according to the length of the mounting shaft 21, and the distance between the second mounting base 12 and the first mounting base 11 is adjusted so that both ends of the mounting shaft 21 are rotatably connected to the first mounting base 11 and the second mounting base 12 respectively, thus completing the installation and fixing of the cutter shaft assembly 20. The subsequent inspection process is the same as before, that is, after the blade 22 is installed, the inspection is completed by moving the inspection piece 31 axially to cooperate with the rotation of the mounting shaft 21, and the defective blade 22 is replaced.

[0046] Therefore, by setting the first mounting base 11 and the second mounting base 12 opposite to each other, a stable support is provided for the mounting shaft 21, ensuring its smooth rotation. The second mounting base 12 slides through the first slide block 19, which can flexibly adapt to mounting shafts 21 of different lengths, expanding the applicability of the tooling and ensuring that the cutter shafts of various helical blades 22 can be securely installed and accurately inspected, thereby improving the versatility and practicality of the tooling.

[0047] In addition, a pad 112 is provided between the first mounting base 11 and the base 10. The pad 112 can raise the pad 112 so that the first mounting base 11 and the second mounting base 12 are at the same installation height.

[0048] As an optional implementation method, see [link / reference]. Figure 2 The base 10 is provided with a first guide rail 13, which extends along the axial direction of the mounting shaft 21. Correspondingly, the bottom of the first slide block 19 is provided with a first guide groove 191, which slides in cooperation with the first guide rail 13.

[0049] Based on this structure, when adjusting the position of the second mounting base 12, since the first guide groove 191 at the bottom of the first slide block 19 slides in a sliding fit with the first guide rail 13 on the base 10, the first slide block 19 can be moved smoothly along the axial direction of the mounting shaft 21, thereby driving the second mounting base 12 to be adjusted to a suitable position to match the length of the mounting shaft 21.

[0050] In this way, the sliding cooperation between the first guide rail 13 and the first guide groove 191 provides precise guidance for the movement of the second mounting base 12, ensuring that it slides smoothly along the axial direction of the mounting shaft 21, avoiding deviation, ensuring the coaxiality of the supports at both ends of the mounting shaft 21, thereby improving the stability of the rotation of the mounting shaft 21, providing a more reliable guarantee for the detection accuracy of the blade 22, and making the position adjustment of the second mounting base 12 smoother and more efficient.

[0051] As an optional implementation, one end of the mounting shaft 21 is provided with a first connecting shaft 24, and the other end of the mounting shaft 21 is provided with a second connecting shaft 25, both of which are coaxially arranged with the mounting shaft 21. Furthermore, the first mounting base 11 is provided with a first rotating part 111, and the second mounting base 12 is provided with a second rotating part 122, both of which are concentrically arranged along the axial direction of the mounting shaft 21. The first connecting shaft 24 is rotatably connected to the first rotating part 111, and the second connecting shaft 25 is rotatably connected to the second rotating part 122.

[0052] Based on this structure, when installing the mounting shaft 21, the first connecting shaft 24 at one end of the shaft is connected to the first rotating part 111 of the first mounting base 11, and the second mounting base 12 is slid to connect the second connecting shaft 25 at the other end of the mounting shaft 21 to the second rotating part 122 of the second mounting base 12, thus completing the rotational connection assembly of the mounting shaft 21.

[0053] In this way, the first connecting shaft 24, the second connecting shaft 25 are coaxial with the mounting shaft 21, and the first rotating part 111 and the second rotating part 122 are concentric, which can ensure that the axis of the mounting shaft 21 is stable after installation and will not produce additional offset or shaking during rotation. This further improves the coaxiality and stability of the rotation of the mounting shaft 21, providing a more reliable basis for the accurate detection of the cutting circle 23 of the blade 22 and ensuring the detection accuracy.

[0054] The first rotating part 111 and the second rotating part 122 can both be rotating holes or rotating grooves, and the rotating parts are rotatably connected to the connecting shaft through bearings 29. The bearings 29 can be deep groove ball bearings 29, cylindrical roller bearings 29, etc. The bearings 29 can reduce the frictional resistance when the connecting shaft rotates, making the mounting shaft 21 rotate more smoothly and stably, reducing the rotational error caused by friction, further ensuring the coaxiality and stability of the mounting shaft 21 rotation, and improving the accuracy of the cutting circle 23 detection by the blade 22.

[0055] As an optional implementation, the base 10 is provided with a plurality of first locking portions 14 along the axial direction of the mounting shaft 21. (See also...) Figure 1 The second mounting base 12 is provided with a connector 15 and a locking member 16 on one side. Specifically, one end of the connector 15 is connected to the second mounting base 12, and the other end of the connector 15 is provided with a second locking part 151. The second locking part 151 is used to correspond to different first locking parts 14 when the second mounting base 12 moves along the axial direction of the mounting shaft 21, and the locking member 16 is used to connect the first locking part 14 and the second locking part 151 when the second locking part 151 is correspondingly set with the first locking part 14.

[0056] Based on this structure, when adjusting the position of the second mounting base 12, firstly, slide the second slide block 18 according to the length of the mounting shaft 21, causing it to move the second mounting base 12, and align the second locking part 151 on the connecting member 15 with the corresponding first locking part 14 on the base 10. At this time, the distance between the first mounting base 11 and the second mounting base 12 is adapted to the length of the mounting shaft 21. Then, use the locking member 16 to connect and fix the first locking part 14 and the second locking part 151, completing the position locking of the second mounting base 12.

[0057] Therefore, by cooperating with the first locking part 14 and the second locking part 151, the second mounting base 12 can be quickly locked after being adjusted to a suitable position, preventing it from being displaced during the testing process due to external forces such as the rotation of the mounting shaft 21, ensuring the stability of the mounting shaft 21 support, thereby ensuring the testing accuracy, and improving the convenience of fixing the position of the second mounting base 12.

[0058] As an optional implementation, the first locking part 14 is a first threaded hole, and the second locking part 151 is a second threaded hole. See again. Figure 2 The locking member 16 includes a locking post 161 and a rotating arm 162, with the rotating arm 162 connected to one end of the locking post 161. The outer periphery of the locking post 161 is provided with a third threaded hole, which is used to sequentially screw into the first threaded hole and the second threaded hole to lock the second mounting seat 12 onto the base 10.

[0059] Based on this structure, after sliding the second mounting base 12 to a suitable position, align the second threaded hole with the corresponding first threaded hole, and rotate the locking pin 161 by rotating the arm 162, so that its outer third thread is screwed into the first threaded hole and the second threaded hole in sequence, thereby completing the locking of the second mounting base 12.

[0060] During unlocking, the rotating arm 162 is twisted in the opposite direction, causing the locking pin 161 to rotate in the opposite direction and gradually exit the first threaded hole and the second threaded hole, thus completing the unlocking.

[0061] In this way, the locking method through the threaded connection is stable and reliable, which can effectively prevent the displacement of the second mounting base 12 and ensure the stability during testing; the rotating arm 162 is easy to operate and improves the locking efficiency.

[0062] In addition, the first locking part 14 can be a pin hole, the second locking part 151 can be a corresponding pin hole, and the locking member 16 can be a positioning pin. Alternatively, the first locking part 14 can be a slot, and the second locking part 151 can be a locking block, which locks the device by snapping it in. In this case, the locking member 16 is not required.

[0063] As an optional implementation, the base 10 is provided with a second guide rail 17 and a second slide 18. Specifically, the second guide rail 17 extends axially along the mounting shaft 21, and the bottom of the second slide 18 is provided with a second guide groove 181, wherein the second guide groove 181 slides in engagement with the second guide rail 17. In addition, the detection element 31 is mounted on the second slide 18.

[0064] Based on this structure, when the detection component 31 detects the blade 22, it can be manually or electrically pushed to push the second slide 18 on which the detection component 31 is installed, so that the second guide groove 181 at its bottom slides along the second guide rail 17 on the base 10, thereby driving the detection component 31 to move smoothly along the mounting shaft 21, and cooperate with the rotation of the mounting shaft 21 to complete the detection of the blade edge of the blade 22.

[0065] In this way, the second guide rail 17 and the second guide groove 181 slide together, providing precise guidance for the axial movement of the detection component 31, ensuring smooth movement and accurate trajectory of the detection component 31, avoiding deviation that affects detection accuracy, and making the operation of the detection component 31 smoother and improving detection efficiency. In addition, this structure also enhances the stability and reliability of the movement of the detection assembly 30.

[0066] As an optional implementation, the detection assembly 30 further includes a magnetic base 32, which is mounted on the second slide 18. The detection element 31 is mounted on the magnetic base 32.

[0067] Based on this structure, during assembly, the magnetic base 32 is mounted on the second slide 18, and then the testing piece 31 is mounted onto the magnetic base 32. Before testing, the angle and position of the testing piece 31 are adjusted using the universal adjustment function of the magnetic base 32 according to the position of the blade 22, so that it is aligned with the testing point; at the same time, the fine adjustment function of the magnetic base 32 is used to precisely calibrate the position of the testing piece 31. Then, the second slide 18 is pushed, allowing the testing piece 31 to move along the second guide rail 17 with the second slide 18, and the testing is completed in conjunction with the rotation of the mounting shaft 21. If the position of the testing piece 31 needs to be adjusted, the magnetic base 32 can be directly operated for adjustment.

[0068] It should be noted that the magnetic base 32 has a strong adsorption force, which can firmly fix the detection piece 31 on the second slide 18, avoiding the impact of the detection piece 31 shaking during the detection process on the accuracy; and its universal adjustment and fine adjustment functions can flexibly adapt to the blades 22 with different helix angles and positions, making it convenient to quickly align the detection point, greatly improving the flexibility and accuracy of the positioning of the detection piece 31, thereby improving the overall detection efficiency and accuracy, and is especially suitable for scenarios with high requirements for detection position.

[0069] As an optional implementation method, see [link / reference]. Figure 4 Item 31 being tested includes a dial indicator.

[0070] Based on this structure, when using the testing component 31, the dial indicator is mounted on the magnetic base 32. Using the adjustment function of the magnetic base 32, the dial indicator's probe is gently brought into contact with the highest point of the blade 22. After zeroing the dial indicator, the mounting shaft 21 is started to rotate, simultaneously pushing the second slide 18 to move the dial indicator axially along the mounting shaft 21.

[0071] Specifically, first align the dial indicator with the blade 22 at one end of the mounting shaft 21. Then, during the rotation of the mounting shaft 21, record the maximum and minimum readings of the dial indicator. The difference between the two readings is the circular runout of the cutting circle 23 of the blade 22 at that position. Subsequently, move the second slide 18 to align the dial indicator with the next blade 22. In this way, the dial indicator probe can contact the cutting edge of each rotating blade 22 in sequence, and the swing of the dial indicator pointer is recorded. The maximum swing value of the pointer is recorded, which is the circular runout of the corresponding blade 22.

[0072] Because of its high measurement accuracy, the dial indicator can precisely capture the minute displacement of the cutting edge 22 during rotation, accurately reflecting the circular runout of the cutting circle 23, and providing precise data for judging whether the cutting edge 22 is qualified. In conjunction with the magnetic base 32 and the second slide 18, it can achieve full-length inspection of the spirally arranged cutting edges 22, ensuring that the selected cutting edges 22 can form the required cutting circle 23, effectively guaranteeing the quality of subsequent machining. At the same time, the dial indicator provides intuitive readings and is easy to operate, improving inspection efficiency and the accuracy of judgment.

[0073] In addition, the inspection component 31 can also be a dial indicator. Dial indicators have high measurement accuracy and can meet the inspection requirements of general spiral planer cutting circle 23. The readings are intuitive and the operation is simple. They are suitable for scenarios where the accuracy requirements are slightly lower than those of dial indicators, which can reduce the inspection cost.

[0074] The detection component 31 can also be a laser displacement sensor. In use, the laser displacement sensor is mounted on the magnetic base 32, and the sensor is calibrated so that its laser beam is aligned with the blade 22. The mounting shaft 21 is then rotated, moving the second slide 18. The sensor collects the blade displacement data in real time and transmits it to the supporting equipment. The equipment automatically analyzes the data to determine the circular runout and whether the blade 22 is qualified. It is worth noting that the laser displacement sensor features non-contact measurement, avoiding wear on the blade. It also offers fast measurement speed, high data accuracy, and automated detection, making it suitable for batch testing scenarios and significantly improving testing efficiency.

[0075] As an optional implementation method, see [link / reference]. Figure 5 The mounting shaft 21 is provided with multiple bosses 26. Specifically, the bosses 26 extend spirally along the axial direction of the mounting shaft 21, and the multiple bosses 26 are spaced apart circumferentially along the mounting shaft 21. Each boss 26 is provided with multiple mounting grooves, and the blade 22 is installed in a corresponding mounting groove. In addition, a receiving groove 28 is provided between two adjacent bosses 26.

[0076] Based on this structure, during assembly, the blades 22 are first installed one by one into the mounting slots of the bosses 26, and then the blades 22 are fixed in the mounting slots using fasteners such as countersunk screws and bolts. Since the bosses 26 extend spirally along the mounting shaft 21 and are spaced circumferentially, the blades 22 will be arranged in a spiral pattern accordingly.

[0077] During testing, the mounting shaft 21 rotates, causing the blades 22 to rotate, and the testing piece 31 moves axially to test the cutting edges of each blade 22. The receiving groove 28 between adjacent bosses 26 can hold sawdust when the cutter shaft planes the wood.

[0078] The spiral extension and circumferential spacing of the boss 26 provide a precise spiral arrangement and installation benchmark for the blades 22, ensuring that the installation position of the blades 22 is uniform and standardized, and reducing detection errors caused by installation position deviations. The mounting slots correspond one-to-one with the blades 22, enabling quick positioning and installation of the blades 22, and improving assembly efficiency.

[0079] In summary, the tool shaft inspection fixture of this application can be adapted to mounting shafts 21 of different lengths. Through the sliding second mounting base 12, the guide rail and groove cooperation, and the locking structure, the mounting shaft 21 is ensured to be stably installed and rotate smoothly, providing a reliable foundation for inspection. The spiral boss 26 and the mounting groove ensure precise and standardized spiral arrangement of the cutting inserts 22, reducing installation deviations. Using the sliding inspection component 30, combined with the magnetic base 32, dial indicator, and other inspection components 31, the cutting edges of the spirally arranged cutting inserts 22 can be comprehensively and accurately inspected, accurately identifying cutting inserts 22 with excessive circular runout. Finally, by screening and replacing unqualified cutting inserts 22, the accuracy of the cutting circle 23 is ensured, machining quality is guaranteed, production costs are reduced, and production stability and equipment versatility are improved.
