Description

Technical Field

[0001] This utility model relates to the field of saw blade processing application technology, and in particular to a drilling structure for rapid positioning of holes in the saw blade substrate. Background Technology

[0002] In the processing of saw blade substrate, hole drilling is one of the key processes. Traditional saw blade substrate drilling equipment often suffers from low positioning efficiency and poor positioning accuracy.

[0003] During positioning, the saw blade position needs to be adjusted manually and repeatedly, which not only consumes a lot of time, but is also prone to hole position deviation due to human operation error. At the same time, the traditional equipment does not have a good fixing effect on the saw blade, and the saw blade is prone to shaking during drilling, which further affects the drilling quality and cannot meet the needs of large-scale, high-precision saw blade processing. Therefore, this utility model proposes a drilling structure for rapid positioning of hole positions in the saw blade base. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a drilling structure for rapid positioning of hole positions in saw blade substrate, so as to achieve rapid and accurate positioning and stable clamping of saw blade substrate, thereby improving drilling efficiency and quality.

[0005] To solve the above technical problems, the present invention adopts a technical solution as follows: a saw blade body hole positioning drilling structure is provided, including a base, a rotating mechanism is rotatably connected to the top of the base, a positioning structure is fixedly connected to the top of the rotating mechanism, and a saw blade body is sleeved on the outer wall of the positioning structure. The positioning structure forms a basic positioning of the saw blade body, and the rotating mechanism realizes the circumferential rotation of the saw blade body. A clamping assembly is fixedly connected to the edge of the rotating mechanism to press and fix the saw blade body placed on top of the rotating mechanism. A drilling mechanism is bolted to one side of the base to perform drilling operations on the saw blade body after different rotation angles.

[0006] The present invention is further configured such that: the rotating mechanism includes a rotating motor bolted to the bottom of the base, the output shaft of the rotating motor is fixedly connected to a drive gear, the outer wall of the drive gear is meshed with an internal gear ring, the top of the internal gear ring is fixedly connected to a turntable, and the bottom center of the turntable is fixedly connected to a rotating shaft.

[0007] With the above technical solution, when the rotating motor is working, it drives the drive gear to rotate. The drive gear drives the internal gear ring and the top turntable to rotate synchronously through meshing with the internal gear ring. The rotating shaft at the bottom of the turntable can rotate along the top of the base, providing support and guidance for the rotation of the turntable, ensuring that the turntable drives the saw blade body to rotate smoothly in a circular motion, so as to adjust the drilling position of the saw blade body.

[0008] The present invention is further configured such that both the turntable and the rotating shaft are rotatably connected to the top of the base.

[0009] Through the above technical solution, the rotational connection between the turntable and the base, together with the rotational cooperation between the rotating shaft and the base, forms a double rotational support structure. This structure can effectively distribute the weight of the turntable and the saw blade body, avoid excessive force on a single support point causing rotational jamming, and at the same time ensure the coaxiality of the turntable during rotation, thereby improving the accuracy of the saw blade body angle adjustment.

[0010] The present invention is further configured such that: the positioning structure includes a positioning post fixed at the center of the top of the turntable, and multiple elastic support plates are equidistantly distributed on the outer wall of the positioning post in the circumferential direction, and the outer walls of the multiple elastic support plates abut against the inner wall of the central hole of the saw blade body.

[0011] With the above technical solution, when the center hole of the saw blade body is fitted into the positioning post, the elastic support plate on the outer wall of the positioning post will undergo elastic deformation due to the compression of the center hole of the saw blade; the reaction force generated by the elastic deformation makes the elastic support plate tightly press against the inner wall of the center hole of the saw blade, realizing the rapid centering and positioning of the saw blade body; at the same time, the elastic characteristics of the elastic support plate can be adapted to the center holes of saw blades with different diameters within a certain range, improving the versatility of the positioning structure.

[0012] The present invention is further configured such that: the clamping assembly includes a plurality of clamping cylinders circumferentially distributed at equal intervals on the bottom of the turntable; each of the driving rods of the plurality of clamping cylinders is bolted to a clamping block; both sides of the plurality of clamping blocks are rotatably connected to a plurality of fixing blocks fixed on the outer arc wall of the turntable via connecting shafts; and elastic pads are provided at the clamping surfaces of the plurality of clamping blocks and the saw blade body.

[0013] With the above technical solution, when the clamping cylinder drive rod extends, it will push the clamping block to rotate around the connecting shaft on the fixed block. Since the rotation trajectory of the clamping block is towards the saw blade body, the top of the clamping block will eventually press against the edge of the saw blade body, thus achieving clamping and fixing of the saw blade. Multiple clamping components distributed circumferentially can ensure that the saw blade is subjected to uniform force, avoiding deformation of the saw blade due to unilateral force. The elastic pad of the clamping surface can buffer the clamping force, prevent the saw blade surface from being crushed, and at the same time increase friction and improve clamping stability.

[0014] The present invention is further configured such that: the drilling mechanism includes a mounting plate bolted to one side of the base, an adjusting cylinder is bolted to the side wall of the mounting plate near the top, the end face of the drive rod of the adjusting cylinder passes through the mounting plate and is fixedly connected to a connecting plate, and a drilling machine is bolted to the side wall of the connecting plate.

[0015] Through the above technical solution, the adjusting cylinder can drive the drive rod to extend and retract axially, thereby moving the connecting plate and the drilling machine on the connecting plate closer to or away from the saw blade body; when the saw blade body is adjusted to the target angle by the rotating mechanism, the adjusting cylinder pushes the drilling machine to the drilling position, and the drilling machine can start to complete the drilling operation; the mounting plate provides stable support for the adjusting cylinder and the drilling machine, ensuring the stability of the equipment structure during the drilling process.

[0016] The present invention is further configured such that: on the side of the connecting plate away from the drilling machine, near the end face, there are symmetrical bolted auxiliary rods; the two auxiliary rods respectively penetrate the mounting plate, and the outer walls of the two auxiliary rods are wrapped with stabilizing springs; the end faces of the two auxiliary rods are fixedly connected to limit plates, and the two ends of the stabilizing springs are respectively pressed against the mounting plate and the limit plate.

[0017] With the above technical solution, when the connecting plate moves, it will drive the auxiliary rod to move synchronously along the through hole of the mounting plate. The auxiliary rod can limit the movement direction of the connecting plate and prevent the connecting plate from shifting or shaking due to the weight of the drilling machine or the impact force of drilling. The stabilizing spring will extend and retract when the auxiliary rod moves. Its elasticity can buffer the impact force during the movement of the connecting plate, so that the drilling machine can smoothly approach or move away from the saw blade and avoid drilling position deviation due to excessive movement speed. The limiting plate can prevent the auxiliary rod from disengaging from the through hole of the mounting plate and ensure the integrity of the auxiliary structure.

[0018] The beneficial effects of this utility model are as follows: 1. The saw blade substrate hole positioning drilling structure proposed in this utility model achieves rapid positioning and precise angle adjustment of the saw blade substrate through the cooperation of the positioning structure and the rotating mechanism. The elastic support in the positioning structure can quickly center the saw blade without repeated manual calibration, which greatly improves the positioning efficiency. The rotating mechanism drives the saw blade to rotate smoothly in a circular motion through gear meshing transmission. With the help of the double rotating support structure, the accuracy of the saw blade angle adjustment is ensured, effectively avoiding the hole position offset problem and meeting the high-precision processing requirements. 2. The saw blade substrate hole positioning drilling structure proposed in this utility model ensures the stability and efficiency of the saw blade drilling process through the synergistic effect of the clamping components and the drilling mechanism. The circumferentially distributed clamping components can uniformly press the saw blade, and the elastic pads prevent pressure damage and increase friction to prevent the saw blade from shaking. The drilling mechanism realizes the rapid adjustment of the drilling machine position through the adjustment cylinder, and the auxiliary rod and stabilizing spring further ensure the smooth movement of the drilling machine, improving the drilling operation efficiency and accuracy, and is suitable for large-scale processing and production of saw blades.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] like Figures 1-3 As shown, a saw blade body hole positioning drilling structure includes a base 1. A rotating mechanism 2 is rotatably connected to the top of the base 1. The rotating mechanism 2 includes a rotating motor 21 bolted to the bottom of the base 1. The output shaft of the rotating motor 21 is fixedly connected to a drive gear 22. An internal gear ring 23 is meshed with the outer wall of the drive gear 22. A turntable 24 is fixedly connected to the top of the internal gear ring 23. The turntable 24 and the rotating shaft 25 are both rotatably connected to the top of the base 1. The rotatable connection between the turntable 24 and the base 1, combined with the rotatable engagement between the rotating shaft 25 and the base 1, forms a double rotating support structure. This structure can effectively distribute the rotation between the turntable 24 and the saw blade body 5. The weight is controlled to avoid excessive force on a single support point, which could cause the rotation to jam. At the same time, the coaxiality of the turntable 24 during rotation is ensured, thereby improving the accuracy of the angle adjustment of the saw blade body 5. A rotating shaft 25 is fixedly connected to the bottom center of the turntable 24. When the rotating motor 21 is working, it drives the drive gear 22 to rotate. The drive gear 22 drives the internal gear ring 23 and the top turntable 24 to rotate synchronously through meshing transmission with the internal gear ring 23. The rotating shaft 25 at the bottom of the turntable 24 can rotate along the top of the base 1 to provide support and guidance for the rotation of the turntable 24, ensuring that the turntable 24 drives the saw blade body 5 to rotate smoothly in a circular motion to adjust the drilling position of the saw blade body 5.

[0023] like Figure 2As shown, a positioning structure 3 is fixedly connected to the top of the rotating mechanism 2. The saw blade body 5 is sleeved on the outer wall of the positioning structure 3. The positioning structure 3 forms a basic positioning of the saw blade body 5, and the rotating mechanism 2 realizes the circumferential rotation of the saw blade body 5. The positioning structure 3 includes a positioning post 31 fixed at the center of the top of the turntable 24. Multiple elastic support plates 32 are evenly distributed in the circumferential direction on the outer wall of the positioning post 31, and the outer walls of the multiple elastic support plates 32 are pressed against the inner wall of the central hole of the saw blade body 5. When the central hole of the saw blade body 5 is fitted into the positioning post 31, the elastic support plates 32 on the outer wall of the positioning post 31 will undergo elastic deformation due to the compression of the central hole of the saw blade. The reaction force generated by the elastic deformation makes the elastic support plates 32 tightly press against the inner wall of the central hole of the saw blade, realizing the rapid centering and positioning of the saw blade body 5. At the same time, the elastic characteristics of the elastic support plates 32 can be adapted to the central holes of saw blades with different diameters within a certain range, improving the versatility of the positioning structure.

[0024] like Figure 2 and Figure 3 As shown, a clamping assembly 4 is fixedly connected to the edge of the rotating mechanism 2 to clamp and fix the saw blade body 5 placed on top of the rotating mechanism 2. The clamping assembly 4 includes multiple clamping cylinders 41 circumferentially distributed at the bottom of the turntable 24. The drive rod end faces of the multiple clamping cylinders 41 are all bolted to clamping blocks 42. Both sides of the multiple clamping blocks 42 are rotatably connected to multiple fixing blocks 43 fixed on the outer arc wall of the turntable 24 through connecting shafts. And at the clamping surfaces of the multiple clamping blocks 42 and the saw blade body 5, a clamping block is provided. With an elastic pad, when the clamping cylinder 41 extends its drive rod, it pushes the clamping block 42 to rotate around the connecting shaft on the fixed block 43. Since the rotation trajectory of the clamping block 42 is towards the saw blade body 5, the top of the clamping block 42 will eventually press against the edge of the saw blade body 5, thus achieving clamping and fixing of the saw blade. Multiple clamping components 4 distributed circumferentially can ensure that the saw blade is subjected to uniform force and avoid deformation of the saw blade due to unilateral force. The elastic pad on the clamping surface can buffer the clamping force, prevent the saw blade surface from being crushed, and increase friction to improve clamping stability.

[0025] like Figure 1 and Figure 4As shown, a drilling mechanism 6 is bolted to one side of the base 1 to perform drilling operations on the saw blade body 5 after different rotation angles. The drilling mechanism 6 includes a mounting plate 61 bolted to one side of the base 1. An adjusting cylinder 62 is bolted to the side wall of the mounting plate 61 near the top. The end face of the drive rod of the adjusting cylinder 62 passes through the mounting plate 61 and is fixedly connected to a connecting plate 63. A drilling machine 64 is bolted to the side wall of the connecting plate 63. The adjusting cylinder 62 can drive the drive rod to extend and retract axially, thereby driving the connecting plate 63 and the drilling machine 64 on the connecting plate 63 to move closer to or away from the saw blade body 5. When the saw blade body 5 is adjusted to the target angle by the rotation mechanism, the adjusting cylinder 62 pushes the drilling machine 64 to move to the drilling position, and the drilling machine 64 starts to complete the drilling operation. The mounting plate 61 provides stable support for the adjusting cylinder 62 and the drilling machine 64 to ensure the stability of the equipment structure during the drilling process. Auxiliary rods 65 are symmetrically bolted to the side of the connecting plate 63 away from the drilling machine 64, near the end face. The two auxiliary rods 65 pass through the mounting plate 61, and each is wrapped with a stabilizing spring 66. Limiting plates 67 are fixedly connected to the end faces of both auxiliary rods 65. The two ends of the stabilizing springs 66 abut against the mounting plate 61 and the limiting plate 67, respectively. When the connecting plate 63 moves, it drives the auxiliary rods 65 to move synchronously along the through holes of the mounting plate 61. The auxiliary rods 65 restrict the direction of movement of the connecting plate 63, preventing it from shifting or shaking due to the weight of the drilling machine 64 or the impact force of drilling. The stabilizing springs 66 extend and retract when the auxiliary rods 65 move, and their elasticity buffers the impact force during the movement of the connecting plate 63, allowing the drilling machine 64 to smoothly approach or move away from the saw blade, avoiding drilling position deviation due to excessive movement speed. The limiting plate 67 prevents the auxiliary rods 65 from detaching from the through holes of the mounting plate 61, ensuring the integrity of the auxiliary structure.

[0026] In use, the rotating motor 21 is started. The rotating motor 21 drives the turntable 24 and the saw blade body 5 to rotate to the target angle through the meshing of the drive gear 22 and the internal gear ring 23. After the angle adjustment is completed, the adjusting cylinder 62 is started. The adjusting cylinder 62 pushes the connecting plate 63 and the drilling machine 64 to move towards the saw blade. At the same time, the auxiliary rod 65 and the stabilizing spring 66 ensure that the drilling machine 64 moves smoothly. When the drilling machine 64 reaches the designated drilling position, the drilling machine 64 is started to complete the drilling operation. After drilling a single hole, the above angle adjustment and drilling steps can be repeated to achieve continuous drilling of multiple holes in the saw blade body 5.
