Description

Technical Field

[0001] This utility model relates to the field of saw tooth processing technology, and in particular to a saw tooth side processing device. Background Technology

[0002] As a basic cutting tool, the machining accuracy of saw teeth directly affects cutting efficiency, lifespan, and surface quality. Grinding forming technology, due to its high precision, high hardness, and strong material adaptability, has become the mainstream processing method for high-end products such as carbide saw blades and diamond saw blades.

[0003] In existing technologies, the backlash angle of the saw teeth is controlled by electric adjustment. Electric adjustment requires the use of high-precision linear motors and feedback systems, which results in high equipment costs and restricts the application by small and medium-sized manufacturers.

[0004] Therefore, it is necessary to improve the existing sawing equipment to solve the problem of excessively high equipment costs caused by its electric adjustment method for controlling the backlash angle.

[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 side processing device that can effectively solve the problem of excessively high equipment costs caused by the existing saw tooth processing devices controlling the side clearance angle through electric adjustment.

[0007] To achieve the above objectives, this utility model provides a sawtooth side processing device, comprising:

[0008] A saw blade fixing module, the saw blade fixing module including a saw blade fixing shaft for inserting into the saw blade hole of the saw blade to be processed, and a pneumatic clamping assembly for clamping the saw blade to be processed from both sides;

[0009] Two side grinding modules are arranged on both sides of the saw blade to be processed. Each side grinding module includes a manually adjustable rotary platform, a grinding unit installed on top of the manually adjustable rotary platform, and an axial side grinding direct drive mechanism located below the manually adjustable rotary platform. The axial side grinding direct drive mechanism is used to drive the manually adjustable rotary platform to move closer to or away from the saw teeth along the axial direction of the saw blade to be processed.

[0010] The manually adjustable rotary platform includes:

[0011] Platform base plate, which is connected to the drive end of the axial side grinding direct drive mechanism;

[0012] A vertical pivot is located on the platform base plate near the apex corner of the saw blade to be processed;

[0013] A platform rotating plate, wherein the platform rotating plate is rotatably connected to the platform base plate via the vertical rotating shaft;

[0014] A manual adjustment component is connected to the platform rotating plate and is used to drive the platform rotating plate to rotate relative to the platform base plate around the vertical rotating axis, so as to adjust the side clearance angle between the side of the saw teeth and the grinding unit.

[0015] Optionally, the saw blade fixing module is a damping rotating shaft.

[0016] Optionally, the saw blade fixing module further includes a saw tooth shifting direct drive mechanism located diagonally above the saw blade to be processed and used to push the saw teeth on the saw blade to be processed downward to realize saw tooth shifting.

[0017] Optionally, the manually adjustable rotary platform includes:

[0018] A rotating lead screw, which is threadedly connected to the platform base plate;

[0019] A hand-tightening nut, which is fixed to one end of the rotating screw;

[0020] A rotary joint, one end of which is rotatably connected to the other end of the rotary lead screw, and the other end of which is rotatably connected to the platform turntable.

[0021] Optionally, the platform base plate is provided with scale markings to indicate the rotational displacement of the platform turntable;

[0022] The platform's rotating plate is fixed with a pointer that points to the scale markings.

[0023] Optionally, the platform rotating plate is provided with a plurality of arc-shaped guide grooves centered on the vertical rotating axis;

[0024] The manually adjustable rotary platform also includes hand-tightening bolts that correspond one-to-one with each of the arc-shaped guide grooves;

[0025] Each of the hand-tightened bolts passes through the arc-shaped guide groove and is then threaded to the platform base plate.

[0026] Optionally, the manually adjustable rotary platform further includes:

[0027] A platform top plate, located above the platform rotating plate, is used to support the grinding unit;

[0028] A radial side-grinding direct drive mechanism is located below the platform top plate and drives the platform top plate to move closer to or further away from the saw teeth along the radial direction of the saw blade to be processed.

[0029] Optionally, the grinding unit includes a grinding wheel head and a rotary drive mechanism for driving the grinding wheel head to rotate.

[0030] Optionally, it also includes a loading spindle for holding unprocessed saw blades and a unloading spindle for holding processed saw blades.

[0031] The beneficial effects of this utility model are as follows: It provides a sawtooth side processing device, the working process of which is as follows:

[0032] S10: Saw blade fixing stage:

[0033] The operator places the saw blade to be processed onto the saw blade fixing shaft; then activates the pneumatic clamping assembly to clamp the saw blade from both sides, ensuring that the saw blade does not move axially during processing;

[0034] The saw blade's fixed pivot can be connected to a rotary drive device (such as a servo motor) to achieve precise indexing rotation of the saw blade, allowing each saw tooth to sequentially enter the processing position.

[0035] S20: Coarse positioning stage:

[0036] The axial side grinding direct drive mechanisms on both sides advance synchronously, driving the entire manually adjustable rotary platform closer to the saw blade until the grinding unit maintains a preset safe distance (about 1mm-2mm) from the side of the saw teeth.

[0037] S30: Angle fine-tuning stage:

[0038] The operator drives the platform to rotate around the vertical axis by manually adjusting the components, which in turn causes the grinding unit to rotate around the vertical axis as well. The rotation directly changes the tilt angle (i.e., the side clearance angle) of the grinding working surface of the grinding unit relative to the side of the saw teeth.

[0039] Adjust the manual adjustment components until the backlash angle meets the processing requirements.

[0040] S40: Dual-sided synchronous processing stage:

[0041] Start the polishing unit;

[0042] The axial side grinding direct drive mechanism advances again, causing the grinding units on both sides to contact the two sides of the saw teeth respectively;

[0043] The grinding amount is controlled by a preset feed program to complete the three-stage processing of rough grinding, fine grinding and finishing.

[0044] S50: Processing Exit Phase

[0045] After completing the current sawtooth machining, the axial side grinding direct drive mechanism drives the grinding wheel back to the safe position;

[0046] The saw blade to be processed is driven to rotate around the fixed pivot of the saw blade by a preset angle, so that the next saw tooth reaches the processing position;

[0047] S60: Repeat the above process until the entire serration is machined.

[0048] Therefore, the saw tooth side processing equipment provided by this utility model replaces the electric adjustment mechanism with a manually adjustable rotary platform, and replaces the expensive linear motor and closed-loop feedback system with a mechanical fine-tuning structure to complete the side processing of the saw teeth. This effectively solves the problem that the existing saw tooth processing equipment achieves side clearance angle control by electric adjustment, resulting in excessively high equipment costs.

[0081] See Figures 1-6 This utility model provides a sawtooth side processing device, comprising:

[0082] The saw blade fixing module 1 includes a saw blade fixing shaft 101 for inserting into the saw blade hole of the saw blade 100 to be processed, and a pneumatic clamping assembly 102 for clamping the saw blade 100 to be processed from both sides.

[0083] Two side grinding modules 2 are arranged on both sides of the saw blade 100 to be processed. Each side grinding module 2 includes a manually adjustable rotary platform 201, a grinding unit 202 mounted on top of the manually adjustable rotary platform 201, and an axial side grinding direct drive mechanism 2018 located below the manually adjustable rotary platform 201. The axial side grinding direct drive mechanism 2018 is used to drive the manually adjustable rotary platform 201 to move closer to or away from the saw teeth along the axial direction of the saw blade 100 to be processed.

[0084] The manually adjustable rotary platform 201 includes:

[0085] Platform base plate 2011, which is connected to the drive end of the axial side grinding direct drive mechanism 2018;

[0086] A vertical rotating shaft 2012 is located on the platform base plate 2011 near the top corner of the saw blade 100 to be processed;

[0087] Platform rotating plate 2013, which is rotatably connected to platform base plate 2011 via vertical rotating shaft 2012;

[0088] The manual adjustment component 2014 is connected to the platform rotating plate 2013 and is used to drive the platform rotating plate 2013 to rotate relative to the platform base plate 2011 around the vertical rotating shaft 2012, so as to adjust the side clearance angle between the side of the saw teeth and the grinding unit 202.

[0089] Specifically, the grinding unit 202 includes a grinding wheel head and a rotary drive mechanism for driving the grinding wheel head to rotate.

[0090] Furthermore, the saw tooth side processing equipment also includes a feeding shaft 4 for placing unprocessed saw blades and a discharging shaft 5 for placing processed saw blades.

[0091] The sawtooth side processing equipment provided in this embodiment operates as follows:

[0092] S10: Saw blade fixing stage:

[0093] The operator takes the saw blade 100 to be processed out of the feeding shaft 4 and puts it into the saw blade fixing shaft 101; then the pneumatic clamping assembly 102 is activated to clamp the saw blade from both sides to ensure that the saw blade does not move axially during the processing.

[0094] The saw blade fixing shaft 101 can be connected to a rotary drive device (such as a servo motor) to achieve precise indexing rotation of the saw blade, so that each saw tooth enters the processing position in sequence.

[0095] S20: Coarse positioning stage:

[0096] The axial side grinding direct drive mechanisms 2018 on both sides advance synchronously, driving the entire manually adjustable rotary platform 201 closer to the saw blade until the grinding unit 202 maintains a preset safe distance (about 1mm-2mm) from the side of the saw teeth.

[0097] S30: Angle fine-tuning stage:

[0098] The operator drives the platform rotating plate 2013 to rotate around the vertical rotating shaft 2012 through the manual adjustment component 2014, which in turn causes the grinding unit 202 to rotate around the vertical rotating shaft 2012. Its rotation directly changes the tilt angle (i.e., the side clearance angle) of the grinding working surface of the grinding unit 202 relative to the side of the saw teeth.

[0099] Adjust the manual adjustment component 2014 until the backlash angle meets the processing requirements.

[0100] S40: Dual-sided synchronous processing stage:

[0101] Start grinding unit 202;

[0102] The axial side grinding direct drive mechanism 2018 advances again, so that the grinding units 202 on both sides contact the two sides of the saw teeth respectively.

[0103] The grinding amount is controlled by a preset feed program to complete the three-stage processing of rough grinding, fine grinding and finishing.

[0104] S50: Processing Exit Phase

[0105] After completing the current sawtooth machining, the axial side grinding direct drive mechanism 2018 drives the grinding wheel to return to the safe position;

[0106] Drive the saw blade 100 to be processed to rotate around the saw blade fixing shaft 101 by a preset angle so that the next saw tooth reaches the processing position;

[0107] S60: Repeat the above process until the entire circle of saw teeth is processed, and finally put the processed saw blade into the unloading spindle 5.

[0108] Therefore, the saw tooth side processing equipment provided by this utility model replaces the electric adjustment mechanism with a manually adjustable rotary platform 201, and replaces the expensive linear motor and closed-loop feedback system with a mechanical fine-tuning structure to complete the side processing of the saw teeth. This effectively solves the problem that the existing saw tooth processing equipment achieves side clearance angle control by electric adjustment, resulting in excessively high equipment costs.

[0109] In this embodiment, the saw blade fixing module 1 is a damping rotating shaft.

[0110] Accordingly, the saw blade fixing module 1 also includes a saw tooth shifting direct drive mechanism 103 located obliquely above the saw blade 100 to be processed and used to push the saw teeth on the saw blade 100 to be processed downward to realize the saw tooth shifting.

[0111] The design of the damping shaft ensures that even if the pneumatic clamping assembly 102 completely releases the saw blade 100 to be processed, the saw blade 100 to be processed will not rotate freely due to the damping effect of the damping shaft, thereby ensuring the stability of the position of each saw tooth on the saw blade 100 to be processed.

[0112] In practice, when switching saw teeth positions, the pneumatic clamping assembly 102 does not completely release the saw blade 100 to be processed; it only loosens it slightly, reducing the clamping force. Then, the saw tooth repositioning direct drive mechanism 103 extends and pushes the nearest saw tooth diagonally downwards, causing the entire saw blade 100 to rotate at a certain angle. During the saw tooth repositioning process, due to the damping effect of the saw blade fixing shaft 101 and the light clamping action of the pneumatic clamping assembly 102, the saw blade does not experience significant inertial rotation due to the pushing action of the saw tooth repositioning direct drive mechanism 103, thus preventing excessive tooth rotation angles that could lead to repositioning failure.

[0113] In this embodiment, the manual adjustment component 2014 includes:

[0114] A rotating lead screw 2014a is threadedly connected to the platform base plate 2011.

[0115] A hand-tightening nut 2014b is fixedly connected to one end of the rotating screw 2014a;

[0116] Rotary joint 2014c, one end of which is rotatably connected to the other end of the rotating lead screw 2014a, and the other end of which is rotatably connected to the platform rotating plate 2013.

[0117] Tightening the hand nut 2014b will drive the rotating screw 2014a to move the rotary joint 2014c back and forth, thereby driving the platform turntable 2013 to rotate in the forward or reverse direction.

[0118] In this embodiment, the platform base plate 2011 is provided with a scale mark 2011a for indicating the rotational displacement of the platform turntable 2013; a pointer 2015 pointing to the scale mark 2011a is fixed on the platform turntable 2013. By observing the change in the value indicated by the pointer 2015 on the scale mark 2011a, the rotational displacement of the platform turntable 2013 can be determined, and thus the current side clearance angle can be determined.

[0119] In this embodiment, the platform rotating plate 2013 is provided with a plurality of arc-shaped guide grooves 2013a centered on the vertical rotating shaft 2012; the manually adjustable rotating platform 201 also includes hand-tightening bolts that correspond one-to-one with each of the arc-shaped guide grooves 2013a; each of the hand-tightening bolts passes through the arc-shaped guide grooves 2013a and is threaded to the platform base plate 2011.

[0120] Generally, when the hand-tightening bolts are tightened, the platform rotating plate 2013 and the platform base plate 2011 are locked, making it difficult to turn the hand-adjusting component 2014 to adjust the rotation angle of the platform rotating plate 2013; when it is necessary to adjust the rotation angle of the platform rotating plate 2013, the hand-tightening bolts need to be loosened in advance.

[0121] In this embodiment, the manually adjustable rotary platform 201 further includes:

[0122] Platform top plate 2016, which is located above the platform rotating plate 2013, is used to support the grinding unit 202;

[0123] Radial side grinding direct drive mechanism 2017, which is located below the platform top plate 2016 and drives the platform top plate 2016 to move closer to or further away from the saw teeth along the radial direction of the saw blade 100 to be processed.

[0124] The radial side grinding direct drive mechanism 2017 drives the platform top plate 2016 to move closer to or further away from the saw teeth along the radial direction of the saw blade 100 to be processed, and the axial side grinding direct drive mechanism 2018 drives the platform top plate 2016 to move closer to or further away from the saw teeth along the axial direction of the saw blade 100 to be processed, thereby realizing the XY bidirectional position adjustment of the grinding unit 202.

[0125] Optionally, a saw blade transfer robot 3 is also included, used to transfer the saw blades of the loading shaft 4, the saw blade fixing shaft 101, and the unloading shaft 5.

[0126] The sawtooth side processing equipment provided in this embodiment has the following advantages:

[0127] (1) Manually adjust the angle positioning of the 2014a rotary screw

[0128] Fine-tuning of the backlash angle is achieved by rotating the lead screw 2014a in conjunction with the dial, replacing the servo motor and thus reducing costs;

[0129] (2) Bidirectional independent direct drive synchronous grinding

[0130] Two sets of axial side grinding direct drive modules control the dual-side grinding wheels respectively, realizing synchronous feed in three stages: roughing, finishing and finishing.

[0131] (3) Damping shaft anti-movement structure

[0132] A damping shaft is set in the pneumatic clamping assembly 102, which works with the shifting direct drive mechanism to adjust the oblique push angle and ensure that the sawtooth indexing error meets the requirements.

[0133] (4) Lockable arc-shaped guide mechanism

[0134] The platform turntable 2013 is equipped with an arc-shaped guide groove 2013a and a hand-tightened bolt for locking, which provides mechanical limit during angle adjustment to prevent side clearance angle drift caused by grinding wheel wobble.

[0135] It should be noted that the direct 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 direct drive mechanism and the rotary drive mechanism.

[0136] 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.
