Abstract
Description
Technical Field
[0001] This utility model relates to the field of saw tooth processing technology, and in particular to a saw tooth back angle processing equipment. Background Technology
[0002] Generally, the edge of a saw blade has a full circle of teeth. During production, one of the processes is to cut the back angle of each tooth one by one. After each tooth is processed, a tooth-changing mechanism is used to move one tooth, causing the entire saw blade to rotate until the next tooth to be processed rotates to the back angle cutting position, and then the back angle cutting operation of the next tooth is carried out.
[0003] In the above process, when the tooth-changing mechanism moves the saw teeth to change the position of the saw teeth to be processed, if the position of the tooth-changing mechanism in contact with the saw teeth is close to the root of the saw teeth, the saw teeth will not be easily damaged. If the position of the tooth-changing mechanism in contact with the saw teeth is close to the tip of the saw teeth, the saw teeth will be easily damaged.
[0004] Therefore, it is necessary to improve the existing saw tooth processing equipment to solve the problem that its tooth changing mechanism is prone to damaging the saw teeth when changing their position.
[0005] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content
[0006] One objective of this invention is to provide a saw tooth back angle processing device that can effectively solve the problem that the existing processing equipment's tooth changing mechanism is prone to damaging the saw teeth when changing their position.

[0008] Vertical mounting plate;
[0009] A saw blade fixing and rotating module includes a rotating base rotatably connected to the vertical mounting plate, a saw blade fixing shaft mounted on the rotating base and used to insert the saw blade into the saw blade hole to be processed, a saw blade clamping assembly mounted on the rotating base and used to clamp the saw blade to be processed, and a base rotation driving mechanism mounted on the vertical mounting plate and driving the rotating base.
[0010] A cutting module is mounted on the vertical mounting plate and located on the side of the saw blade fixing and rotating module, and is used to cut the back angle of the saw teeth on the saw blade to be processed;
[0011] A tooth-changing mechanism is mounted on the vertical mounting plate and is used to move each of the saw teeth to achieve rotational repositioning of each of the saw teeth around the fixed axis of the saw blade.
[0012] The base rotation drive mechanism is used to drive the rotating base to rotate relative to the vertical mounting plate, so that the tooth-changing mechanism is aligned with the gap space between two adjacent saw teeth, so that the tooth-changing mechanism abuts against the root of the saw teeth.

[0014] Optionally, a hand-tightening screw adjustment assembly is provided between the saw blade fixing shaft and the rotating base;
[0015] The hand-tightened lead screw adjustment assembly is used to adjust the initial horizontal distance between the saw blade fixed axis and the cutting module.
[0016] Optionally, the saw blade clamping assembly includes two clamping pads arranged on both sides of the saw blade to be processed, and a clamping linear drive mechanism connected to one of the clamping pads.
[0017] Optionally, the base rotation drive mechanism includes:
[0018] A base pivot shaft rotatably passes through the vertical mounting plate, and the rotating base is fixed to one end of the base pivot shaft;
[0019] A rotating shaft drive plate, the upper end of which is fixedly connected to the other end of the base rotating shaft;
[0020] A drive plate rotating block, the lower end of which is rotatably mounted on the lower end of the rotating shaft drive plate via a rotating block shaft;
[0021] A rotating lead screw, which is threadedly connected to the rotating block of the drive plate;
[0022] A lead screw drive motor is provided, the drive end of which is connected to the rotating lead screw. The drive screw drives the drive plate block to rotate around its own axis and revolve around the base axis, thereby driving the rotating base to rotate.
[0023] Optionally, the drive end of the lead screw drive motor and the rotating lead screw are connected by a universal joint.
[0024] Optionally, it also includes a rotation angle detector for detecting the rotation angle of the shaft drive plate about the base shaft.
[0025] Optionally, the cutting module includes a cutting head and a cutting XYZ three-axis direct drive module that drives the cutting head to perform translational motion.
[0026] Optionally, the gear-changing mechanism includes a transverse shifting pin and a shifting pin XYZ three-way direct drive module that drives the transverse shifting pin to perform translational motion.

[0028] The beneficial effects of this utility model are as follows: It provides a sawtooth back angle processing device, the working process of which is as follows:
[0029] 1. Saw blade installation and fixing
[0030] Step 1: The operator places the saw blade to be processed onto the saw blade fixing shaft, ensuring that the saw blade hole and the fixing shaft are completely fitted together.
[0031] Step 2: Activate the saw blade clamping assembly and apply pressure from both sides of the saw blade to firmly fix the saw blade on the rotating base and prevent it from shaking during processing.
[0032] 2. Initial positioning
[0033] Step 3: The base rotation drive mechanism drives the rotating base, which in turn rotates the saw blade, so that the back angle of the first saw tooth to be processed is aligned with the tool position of the cutting module.
[0034] Regarding the initial position detection: Optionally, the initial position can be confirmed by means of camera visual positioning, photoelectric sensor photoelectric detection, or mechanical limiter stroke detection to ensure the accuracy of the cutting starting point.
[0035] 3. Back angle cutting machining
[0036] Step 4: The cutting module starts and feeds along the preset trajectory:
[0037] Axial feed: Moves towards the plane of the saw blade and contacts the back angle of the saw teeth.
[0038] Radial cutting: Cut along the serrated back angle profile to remove excess material and form the required back angle.
[0039] Step 5: After cutting is completed, the tool automatically returns to a safe position to avoid collision with the saw blade.
[0040] 4. Preparation for changing gears
[0041] Step 6: Fine-tune the base rotation drive mechanism to rotate the base so that the tooth changing mechanism is aligned with the gap between the currently processed saw tooth and the next saw tooth.
[0042] This is to ensure that the subsequent sawtooth actuation mechanism can smoothly insert into the gap between the two teeth, rather than directly impacting the tooth tips.
[0043] Step 7: Slightly loosen the saw blade clamping assembly to reduce the rotational resistance of the saw blade. However, do not completely loosen it to avoid excessive rotation angle due to inertia when pushing the saw teeth to change position later.
[0044] 5. Gear changing process
[0045] Step 8: Gear-changing mechanism operation:
[0046] Extension stage: The tooth-changing mechanism extends towards the saw blade, passing through the gap between the two saw teeth to reach the root of the saw teeth, avoiding direct impact on the tooth tip or middle.
[0047] Drive rotation: The tooth-changing mechanism operates again, pushing the root of the currently processed saw tooth, causing the saw blade to rotate around the fixed axis of the saw blade by one tooth pitch angle (e.g., 360° / number of teeth).
[0048] Reset phase: The tooth-changing mechanism retracts, disengages from the saw blade, and prepares for the next action.
[0049] 6. Circular processing
[0050] Step 9: Repeat steps 3-6 until all serrations are machined.
[0051] Therefore, the saw tooth back angle processing equipment provided by this utility model can effectively solve the problem that the tooth changing mechanism of the existing processing equipment is prone to damage to the saw teeth when changing the position of the saw teeth.

[0074] See Figures 1-4 This utility model provides a sawtooth back angle processing device, comprising:
[0075] Vertical mounting plate 1;
[0076] The saw blade fixing and rotating module 2 includes a rotating base 201 rotatably connected to the vertical mounting plate 1, a saw blade fixing shaft 202 mounted on the rotating base 201 and used to insert the saw blade into the saw blade hole of the saw blade to be processed, a saw blade clamping assembly 203 mounted on the rotating base 201 and used to clamp the saw blade to be processed, and a base rotation driving mechanism 204 mounted on the vertical mounting plate 1 and driven to connect to the rotating base 201.

[0078] Tooth-changing mechanism 4 is mounted on the vertical mounting plate 1 and is used to move each saw tooth to realize the rotational repositioning of each saw tooth around the saw blade fixing shaft 202.
[0079] The base rotation drive mechanism 204 is used to drive the rotating base 201 to rotate relative to the vertical mounting plate 1, so that the tooth changing mechanism 4 is facing the gap space between two adjacent saw teeth, so that the tooth changing mechanism 4 abuts against the root of the saw teeth.
[0080] The sawtooth back angle processing equipment provided in this embodiment operates as follows:
[0081] 1. Saw blade installation and fixing
[0082] Step 1: The operator places the saw blade to be processed onto the saw blade fixing shaft 202, ensuring that the saw blade hole and the fixing shaft are completely fitted together.

[0085] Step 3: The base rotation drive mechanism 204 drives the rotating base 201, causing the saw blade to rotate, so that the back angle of the first saw tooth to be processed is aligned with the tool position of the cutting module 3.
[0086] Regarding the initial position detection: Optionally, the initial position can be confirmed by means of camera visual positioning, photoelectric sensor photoelectric detection, or mechanical limiter stroke detection to ensure the accuracy of the cutting starting point.
[0087] 3. Back angle cutting machining
[0088] Step 4: Cutting module 3 starts and feeds along the preset trajectory:
[0089] Axial feed: Moves towards the plane of the saw blade and contacts the back angle of the saw teeth.

[0095] Step 7: Slightly loosen the saw blade clamping assembly 203 to reduce the rotational resistance of the saw blade. However, do not loosen it completely to avoid excessive rotation angle due to inertia when pushing the saw teeth to change position later.

[0101] 6. Circular processing
[0102] Step 9: Repeat steps 3-6 until all serrations are machined.
[0103] Therefore, the saw tooth back angle processing equipment provided by this utility model can effectively solve the problem that the existing processing equipment's tooth changing mechanism 4 is prone to damaging the saw teeth when changing their position.
[0104] Optionally, the end face of the saw blade fixing shaft 202 is a cylindrical structure or a fan-shaped structure.
[0105] In this embodiment, a hand-tightening screw adjustment assembly 205 is provided between the saw blade fixing shaft 202 and the rotating base 201; the hand-tightening screw adjustment assembly 205 is used to adjust the initial horizontal distance between the saw blade fixing shaft 202 and the cutting module 3.
[0106] By manually fine-tuning the horizontal distance between the saw blade fixed shaft 202 and the cutting module 3, the problems of high cost and complex maintenance of traditional electronic distance adjustment systems are solved. Operators can quickly adapt saw blades of different diameters without relying on complex equipment, making it especially suitable for small and medium-sized processing workshops or scenarios where saw blade specifications are frequently changed.
[0107] In this embodiment, the saw blade clamping assembly 203 includes two clamping pads 2031 arranged on both sides of the saw blade to be processed, and a clamping linear drive mechanism 2032 connected to one of the clamping pads 2031 (the other clamping pad 2031 is fixedly disposed). When the clamping linear drive mechanism 2032 extends, it can drive the two clamping pads 2031 to clamp the saw blade to be processed.
[0108] Furthermore, the clamping force can be adjusted by adjusting the extension stroke of the clamping linear drive mechanism 2032. Optionally, the clamping linear drive mechanism 2032 (such as a servo cylinder) supports 0.1mm-level stroke control, which allows for real-time adjustment of the clamping force during processing, taking into account both anti-loosening and anti-overpressure requirements.
[0109] In this embodiment, the base rotation drive mechanism 204 includes:
[0110] The base pivot 2041 rotates through the vertical mounting plate 1, and the rotating base 201 is fixed to one end of the base pivot 2041.
[0111] A rotating shaft drive plate 2042, the upper end of which is fixedly connected to the other end of the base rotating shaft 2041;
[0112] A drive plate rotating block 2043, the lower end of which is rotatably mounted on the lower end of the rotating shaft drive plate 2042 via a rotating block rotating shaft 2043a;
[0113] A rotating lead screw 2044 is threadedly connected to the drive plate rotating block 2043;
[0114] A lead screw drive motor 2045 is provided, the drive end of which is connected to the rotating lead screw 2044 for driving the drive plate rotating block 2043 to rotate around the rotating block shaft 2043a and revolve around the base shaft 2041, thereby driving the rotating base 201 to rotate.
[0115] Furthermore, the drive end of the lead screw drive motor 2045 and the rotating lead screw 2044 are connected by a universal joint 2046.
[0116] Precise indexing of the rotating base 201 is achieved through the combined motion of the rotating block around two axes (rotation and revolution). For example, every 10° rotation of the lead screw drive motor 2045 drives the rotating block to revolve 0.5°, and with the fine adjustment of the rotating block's rotation, the alignment error between the gear changing mechanism 4 and the tooth backlash is controlled within ±0.02mm. Compared with a purely electric indexing system, this mechanical transmission design has a higher overload resistance and is especially suitable for high-frequency gear changing conditions.
[0117] The application of the universal joint solves the transmission jamming problem caused by the misalignment of the screw drive motor 2045 and the rotating screw 2044 during installation. The universal joint allows for ±3° axial offset compensation, maintaining power transmission stability even after deformation of the base components following long-term operation. For example, after 200 hours of continuous operation, its transmission efficiency can still maintain more than 95% of its initial value, significantly reducing equipment maintenance frequency.
[0118] Optionally, the sawtooth back angle machining equipment also includes a rotation angle detector 2047 for detecting the rotation angle of the shaft drive plate 2042 around the base shaft 2041. The rotation angle detector 2047 (such as a photoelectric encoder) achieves closed-loop control of the tooth changing action by monitoring the rotation angle of the shaft drive plate 2042 in real time. For example, when the detected angle deviation exceeds a set threshold (e.g., ±0.5°), the system automatically triggers a compensation program to adjust the pulse count of the lead screw drive motor 2045, ensuring that the indexing error of each tooth pitch is ≤0.01°. This technology can reduce the tooth changing failure rate from 5% in traditional open-loop control to below 0.3%.
[0119] Optionally, the cutting module 3 includes a cutting head 301 and a cutting XYZ three-axis direct drive module 302 that drives the cutting head 301 to perform translational motion. Three-dimensional trajectory control of the tool is achieved through a linear motor or ball screw.
[0120] Optionally, the gear-changing mechanism 4 includes a transverse shifting pin 401 and a shifting pin XYZ three-way direct drive module 402 that drives the transverse shifting pin 401 to perform translational movement.
[0121] The tooth-changing mechanism 4 drives the transverse shifting pin 401 via an XYZ three-axis direct drive module, achieving precise tooth root positioning and tooth-changing actions. For example, the transverse shifting pin 401 can avoid the tooth tip along a preset trajectory and directly insert into the tooth root gap. With a positioning accuracy of 0.02mm, the tooth tip damage rate is reduced from 8% of traditional pneumatic shifting forks to below 0.5%. This mechanism can also be adapted to saw blades with different tooth pitches (e.g., 3-20mm) and tooth shapes (e.g., trapezoidal teeth, circular arc teeth) through path programming, significantly enhancing its versatility.
[0122] Optionally, the saw blade back angle processing equipment also includes a loading spindle 5 for storing unprocessed saw blades, a unloading spindle 6 for storing processed saw blades, and a transfer robot 7 for transferring saw blades. Using a robot for loading and unloading saw blades improves automation and further increases production efficiency.
[0123] It should be noted that the linear drive mechanism mentioned in this utility model can be a cylinder, hydraulic cylinder, electric cylinder, or motor lead screw linear module, etc., and the rotary drive mechanism mentioned can be a brushed motor, brushless motor, or rotary cylinder, etc. This utility model does not limit the specific structural form of the linear drive mechanism and the rotary drive mechanism.
[0124] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
