Abstract
Description
Technical Field
[0001] This utility model relates to the field of power tool holder technology, specifically a power tool holder that is securely installed. Background Technology
[0002] The power saw blade holder is a highly efficient, precise, and versatile machining tool widely used in mill-turn machines and power turret machining centers. Its integrated structure provides excellent system rigidity and stability, maintaining extremely high machining accuracy even at high speeds. In addition to sawing, the power saw blade holder can perform various operations such as drilling, reaming, and threading, allowing all machining processes for a single part to be completed on the same machine, significantly improving production efficiency.
[0003] According to a public notice (No. CN222199106U) of a saw blade power tool holder, the above application describes a method where a tool is inserted into a socket, and then the drive shaft is rotated to drive the active bevel gear. Subsequently, the driven bevel gear meshing with the active bevel gear drives the worm gear to rotate, which in turn drives the worm wheel to rotate, which in turn drives the first rotating shaft to rotate. Then, the meshing drive gear and the half-tooth ring drive the movable seat to rotate, thereby enabling convenient and quick adjustment of the saw blade's cutting angle.
[0004] However, in the above application, the saw blade needs to be fixed to the tool holder with bolts. During installation, the saw blade needs to be manually supported to align with the mounting hole. If it slips out of hand or is accidentally touched during the operation, it is easy to cause the saw blade to shift. The alignment needs to be repeatedly adjusted, which prolongs the installation time. The edge of the saw blade is sharp. If it slips out of hand during the manual alignment process, it may cut the operator, which poses a high risk of work-related injury. Utility Model Content
[0005] The purpose of this invention is to provide a securely mounted power tool holder to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a stable power tool holder, including a tool holder body and a saw blade, wherein the output shaft of the tool holder body is fixed to the saw blade by bolts, and stabilizing components and protective components are provided on the surface and inside of the tool holder body and the saw blade.
[0007] The stabilizing component includes:
[0008] The fixing post is used to cooperate with the mounting groove to facilitate the docking of the saw blade and the blade holder body;
[0009] The slot is used to mate the rack-and-pinion stabilizer body with the saw blade;
[0010] A cavity is used to support internal mechanisms.
[0011] Preferably, the fixing post is fixed to the side of the saw blade near the blade holder body. The outer surface of the fixing post has a slot. The side of the blade holder body near the saw blade has an installation slot. The blade holder body has an internal cavity. A circular plate is rotatably connected to the inner wall of the cavity. A through hole is formed on the surface of the circular plate. A locking tooth is fixed to the side of the through hole near the center of the circular plate. A gear is rotatably connected to the inner wall of the cavity, and the gear meshes with the locking tooth. A rack is disposed inside the cavity, passing through the installation slot and slidably connected to the blade holder body. A spring is fixed to the end of the rack away from the center of the installation slot, and the end of the spring away from the rack is fixed to the inner wall of the cavity. The through hole is... There are four sets of through holes, and all four sets of through holes are arranged in a circular array with the center of the circular plate as the axis. One of the four sets of through holes has a locking tooth fixed on the side away from the center of the circular plate. The inner wall of the cavity is rotatably connected to a gear, which meshes with the locking tooth. A rack is provided inside the cavity, which meshes with the gear. The end of the rack away from the gear penetrates the cutter body, and the rack is slidably connected to the cutter body. The fixed column is installed in the mounting groove. Through the gear, locking tooth, circular plate, and spring, the rack enters the slot. The cutter body and the saw blade are mutually limited and stabilized. Pressing the rack causes the rack to rotate the gear, which in turn rotates the circular plate. The locking tooth then rotates the gear, which in turn pulls the rack out of the slot.
[0012] Preferably, the protective component includes a rotating ring rotatably connected to the surface of the tool holder body. A retaining plate is fixed to the inner side of the rotating ring. An annular groove is formed on the surface of the rack two away from the gear two, and a sliding groove is formed on the surface of the rack two away from the gear two. The annular groove and the sliding groove communicate with each other. A stabilizing groove is formed on the surface of the tool holder body near the rotating ring. When the rotating ring is rotated, the retaining plate is located in the annular groove, and at the same time, the retaining rod enters the stabilizing groove to limit the rotation ring. The surface of the retaining plate abuts against the inner wall of the annular groove, thereby limiting the rack two.
[0013] Preferably, both the blade holder body and the saw blade have mounting holes on their surfaces for easy bolt fixing.
[0014] Preferably, the end of the rack away from the spring is set as an inclined surface, which allows the rack to move when it is pressed, without affecting the docking of the saw blade and the blade holder body.
[0015] Preferably, the surface of the rotating ring is provided with a locking rod, the locking rod passes through the rotating ring and is slidably connected to the rotating ring, and a second spring is fixed to the surface of the locking rod away from the rotating ring, and the end of the second spring away from the locking rod is fixed to the surface of the rotating ring, which facilitates the stabilization of the rotating ring and prevents the rotating ring from rotating on its own.
[0016] Compared with the prior art, this utility model provides a stable power tool holder, which has the following advantages:
[0017] 1. This securely installed power blade holder, through its protective components, requires the saw blade to be installed on the blade holder body. The fixing post is installed in the mounting slot, and through gear one, retaining tooth one, circular plate, and spring one, the rack one enters the retaining slot. The blade holder body and saw blade are mutually restrained and stabilized, allowing for normal bolt fixing without manual assistance, preventing accidental slippage and affecting installation efficiency. The bolts, combined with the stabilizing components, enhance the stability of the saw blade and blade holder body installation, avoiding the instability caused by a single fixing method.
[0018] 2. The securely installed power tool holder, through the set stabilizing component, when rack one enters the slot, rotates the rotating ring so that the clamping plate is located in the annular groove. At the same time, the clamping rod enters the stabilizing groove to limit the rotating ring and prevent the rotating ring from rotating on its own. The surface of the clamping plate abuts against the inner wall of the annular groove, which can limit rack two and prevent accidental contact, thus avoiding affecting the stability of rack one and the slot.

[0026] like Figures 1-6As shown, this utility model provides a technical solution: a stable power tool holder, including a tool holder body 1 and a saw blade 2. The output shaft of the tool holder body 1 is fixed to the saw blade 2 by bolts. The surface and interior of the tool holder body 1 and the saw blade 2 are provided with a stabilizing component 3 and a protective component 4. The stabilizing component 3 includes: a fixing post 30, a slot 31, a mounting slot 32, a cavity 33, a circular plate 34, a through hole 35, a locking tooth 36, a gear 37, a rack 38, a spring 39, a locking tooth 300, a rack 301, and a gear 302.
[0027] A fixing post 30 is fixed to the side of the saw blade 2 near the blade holder body 1. A slot 31 is formed on the outer surface of the fixing post 30. An installation slot 32 is formed on the side of the blade holder body 1 near the saw blade 2. A cavity 33 is formed inside the blade holder body 1. A circular plate 34 is rotatably connected to the inner wall of the cavity 33. A through hole 35 is formed on the surface of the circular plate 34. A locking tooth 36 is fixed to the side of the through hole 35 near the center of the circular plate 34. A gear 37 is rotatably connected to the inner wall of the cavity 33, and the gear 37 meshes with the locking tooth 36. A rack 38 is provided inside the cavity 33. 38 penetrates the mounting groove 32, and rack 38 is slidably connected to the tool holder body 1. A spring 39 is fixed to the end of rack 38 away from the center of the mounting groove 32. The end of spring 39 away from rack 38 is fixed to the inner wall of cavity 33. Four sets of through holes 35 are provided, and all four sets of through holes 35 are arranged in a circular array with the center of circular plate 34 as the axis. A retaining tooth 300 is fixed to the side of one set of through holes 35 away from the center of circular plate 34. A gear 302 is rotatably connected to the inner wall of cavity 33, and gear 302 meshes with retaining tooth 300. An internal rack 301 is provided, which meshes with a gear 302. The end of the rack 301 away from the gear 302 passes through the tool holder body 1, and the rack 301 is slidably connected to the tool holder body 1. The end of the rack 38 away from the spring 39 is set as an inclined surface. The fixing post 30 is installed in the mounting groove 32. The surface of the fixing post 30 abuts against the inclined surface of the rack 38, which can drive the rack 38 to move into the cavity 33. Through the gear 37, the retaining tooth 36, and the circular plate 34, the consistency of the movement of each rack 38 is improved. When the rack 38 When the position is parallel to the slot 31, spring 39 drives rack 38 into the slot 31, and the blade holder body 1 and saw blade 2 are mutually limited and stable, without the need for manual support, avoiding accidental contact and affecting installation efficiency. When the saw blade 2 needs to be replaced, press rack 301, rack 301 drives gear 302 to rotate, which in turn drives the circular plate 34 to rotate through the locking tooth 300. At this time, locking tooth 36 drives gear 37 to rotate, which can pull rack 38 out of the slot 31, thereby releasing the limitation between saw blade 2 and blade holder body 1, and then it can be separated and replaced normally.
[0028] The protective component 4 includes a rotating ring 40, which is rotatably connected to the surface of the tool holder body 1. A retaining plate 41 is fixed to the inner side of the rotating ring 40. An annular groove 42 is formed on the surface of the rack 2 301 away from the gear 2 302, and a sliding groove 43 is formed on the surface of the rack 2 301 away from the gear 2 302. The annular groove 42 and the sliding groove 43 communicate with each other. A stabilizing groove 46 is formed on the surface of the tool holder body 1 near the rotating ring 40. A retaining rod 44 is provided on the surface of the rotating ring 40, and the retaining rod 44 passes through the rotating ring 40. The locking rod 44 is slidably connected to the rotating ring 40. A spring 45 is fixed to the surface of the end of the locking rod 44 away from the rotating ring 40. The end of the spring 45 away from the locking rod 44 is fixed to the surface of the rotating ring 40. When the rotating ring 40 is rotated, the locking plate 41 is located in the annular groove 42, and at the same time, the locking rod 44 enters the stabilizing groove 46, limiting the rotating ring 40. The surface of the locking plate 41 abuts against the inner wall of the annular groove 42, thus limiting the rack 301 and preventing accidental external contact with the rack 301, which would affect the stability of the rack 38 and the locking groove 31. Mounting holes are provided on the surfaces of both the blade holder body 1 and the saw blade 2 for easy fixing with bolts.
[0029] When the saw blade 2 needs to be installed with the cutter holder body 1, the fixing post 30 is installed in the mounting groove 32. At this time, the surface of the fixing post 30 abuts against the inclined surface of the rack 38, which drives the rack 38 to move into the cavity 33. At the same time, the spring 39 is compressed. As the rack 38 moves, it synchronously drives the gear 37 to rotate. Through the locking tooth 36, it drives the circular plate 34 to rotate synchronously, improving the consistency of the movement of each rack 38. When the position of the rack 38 is parallel to the slot 31, the spring 39 is released, which drives the rack 38 into the slot 31. At the same time, the gear 37 and the locking tooth 36 drive the circular plate 34 to reverse and reset, so that the cutter holder body 1 and the saw blade 2 are mutually limited and stable, without the need for manual support, avoiding accidental contact and affecting installation efficiency. At this time, the mounting holes of the cutter holder body 1 and the saw blade 2 are aligned and bolted. The bolts, together with the stabilizing component 3, improve the stability of the installation of the saw blade 2 and the cutter holder body 1, avoiding the influence of a single fixing method. The stability between the saw blade 2 and the cutter holder body 1 is ensured by simultaneously pulling the locking rod 44, causing it to disengage from the stabilizing groove 46. Simultaneously, the rotating ring 40 is rotated, positioning the locking plate 41 within the annular groove 42. Releasing the locking rod 44, driven by the second spring 45, allows it to re-enter the stabilizing groove 46, thus limiting the rotation ring 40. Simultaneously, the surface of the locking plate 41 abuts against the inner wall of the annular groove 42, limiting the rack 301 and preventing accidental external contact with the rack 301, which could affect the rack 38 and... The stability of the slot 31 is ensured when the saw blade 2 needs to be replaced. The bolts are removed and the rotating ring 40 is rotated to make the sliding groove 43 parallel to the card plate 41. At this time, the rack 2 301 can be pressed normally. The rack 2 301 drives the gear 2 302 to rotate, which in turn drives the circular plate 34 to rotate through the card tooth 2 300. At this time, the card tooth 1 36 drives the gear 1 37 to rotate, which can pull the rack 1 38 out of the slot 31, thereby releasing the limit between the saw blade 2 and the blade holder body 1. At this time, it can be separated and replaced normally.
[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
