Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, specifically to a chamfering tool holder for automotive gear processing. Background Technology

[0002] Gears are toothed mechanical parts that can mesh with each other, and they are widely used in mechanical transmission and the entire mechanical field.

[0003] The existing chamfering tool holders for automotive gear processing rely entirely on the worker's ability to discern the wear of the tools by listening to the sound and vibration during grinding. This requires experienced workers to make such judgments. Furthermore, the tools need to be replaced very frequently, but the tool fixing method is complicated, resulting in a long replacement time. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a chamfering tool holder for automotive gear machining, which has the advantages of predicting tool wear and facilitating tool replacement, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a chamfering tool holder for automotive gear processing, comprising a lifting frame, a rotating motor rotatably connected to the inner wall of the lifting frame, a controller one fixedly installed on the top of the lifting frame, an alarm fixedly installed on the top of the controller one, an extension shell fixedly installed on the outer wall of the lifting frame, a protective sleeve and a swing arm fixedly installed on the outer wall of the rotating motor, an electrode plate fixedly installed on the outer wall of the swing arm, a trigger sensor fixedly installed on the inner wall of the extension shell, a controller two fixedly installed on the outer wall of the trigger sensor, a cutting tool slidably connected to the inner wall of the output shaft of the rotating motor, a protective shell fixedly installed on the outer wall of the protective sleeve, an extension cylinder fixedly installed on the outer wall of the protective shell, an anti-rotation sleeve provided on the outer wall of the extension cylinder, a sliding column slidably connected to the inner wall of the extension cylinder, a threaded column rotatably connected to the outer wall of the sliding column, a limit block fixedly installed on the outer wall of the sliding column, a limit groove formed on the inner wall of the extension cylinder, and a pin fixedly installed on the outer wall of the sliding column.

[0006] As a preferred technical solution of this utility model: the number of electrode plates is two, and the two electrode plates are respectively located on the outer wall of the swing arm and the probe head of the trigger sensor, and the positions of the two electrode plates correspond to each other.

[0007] As a preferred technical solution of this utility model: the threaded post passes through the extension cylinder, and the threaded post and the extension cylinder are connected by threads.

[0008] As a preferred technical solution of this utility model: the shape of the limiting block is adapted to the shape of the inner wall of the limiting groove, and the limiting block is located on the inner wall of the limiting groove.

[0009] As a preferred technical solution of this utility model: the shape of the pin is adapted to the shape of the inner wall of the tool, and the position of the pin corresponds to the inner wall of the tool.

[0010] As a preferred technical solution of this utility model: the outer wall shape of the anti-rotation sleeve is adapted to the inner wall shape of the extension cylinder, and the inner wall shape of the anti-rotation sleeve is adapted to the shape of the threaded column.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This chamfering tool holder for automotive gear processing amplifies the swing amplitude of the rotating motor through a swing arm, thereby causing the external electrode plates to move when the swing arm swings. When the two electrode plates come into contact, it indicates that the swing amplitude of the rotating motor has increased, which in turn indicates that the tool wear is greater. This triggers the trigger sensor, which sends an electrical signal to controller two, which in turn sends an electrical signal to controller one, causing controller one to activate the warning device to remind the operator.

[0012] 2. This chamfering tool holder for automotive gear processing, by removing the anti-rotation sleeve and rotating the threaded column, causes the threaded column to rotate on the inner wall of the extension cylinder through the threaded connection with the extension cylinder. This causes the extension cylinder to drive the sliding column to slide on the inner wall of the extension cylinder, thereby separating the pin from the inner wall of the tool and eliminating the tool's fixing relationship. At this time, pulling the tool outward causes the tool to be extracted from the output shaft of the rotating motor. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 5 A chamfering tool holder for automotive gear processing includes a lifting frame 1, a rotating motor 2 rotatably connected to the inner wall of the lifting frame 1, a controller 3 fixedly installed on the top of the lifting frame 1, an alarm 4 fixedly installed on the top of the controller 3, an extension shell 5 fixedly installed on the outer wall of the lifting frame 1, a protective sleeve 6 and a swing arm 7 fixedly installed on the outer wall of the rotating motor 2, an electrode plate 8 fixedly installed on the outer wall of the swing arm 7, a trigger sensor 9 fixedly installed on the inner wall of the extension shell 5, a controller 10 fixedly installed on the outer wall of the trigger sensor 9, a tool 12 slidably connected to the inner wall of the output shaft of the rotating motor 2, a protective shell 13 fixedly installed on the outer wall of the protective sleeve 6, an extension cylinder 14 fixedly installed on the outer wall of the protective shell 13, an anti-rotation sleeve 15 on the outer wall of the extension cylinder 14, a sliding column 17 slidably connected to the inner wall of the extension cylinder 14, a threaded column 16 rotatably connected to the outer wall of the sliding column 17, a limit block 19 fixedly installed on the outer wall of the sliding column 17, a limit groove 18 formed in the inner wall of the extension cylinder 14, and a pin 11 fixedly installed on the outer wall of the sliding column 17.

[0017] In the above structure, through the electrical connection between controller 2 10 and controller 1 3, and through the electrical connection between controller 1 3 and alarm 4, when the trigger sensor 9 is triggered, the trigger sensor 9 sends an electrical signal to controller 2 10, which in turn sends an electrical signal to controller 1 3, causing controller 1 3 to operate alarm 4 to start, thereby causing alarm 4 to warn the staff.

[0018] In a preferred embodiment, there are two electrode plates 8, and the two electrode plates 8 are located on the outer wall of the swing arm 7 and the probe of the trigger sensor 9, respectively, with the positions of the two electrode plates 8 corresponding to each other.

[0019] In the above structure, the rotation of the rotating motor 2 causes the swing arm 7 to swing, which in turn causes the electrode plate 8 at the end of the swing arm 7 away from the rotating motor 2 to swing. This causes the electrode plate 8 outside the swing arm 7 to move towards the electrode plate 8 outside the trigger sensor 9. When the two electrode plates 8 come into contact, the swing angle of the rotating motor 2 becomes too large, which indicates that the wear of the tool 12 is large. This triggers the trigger sensor 9, which then sends an electrical signal to the controller 10.

[0020] In a preferred embodiment, the threaded post 16 passes through the extension cylinder 14, and the threaded post 16 and the extension cylinder 14 are threadedly connected.

[0021] In the above structure, by rotating the threaded column 16, the threaded column 16 rotates on the inner wall of the extension cylinder 14 through the threaded connection with the extension cylinder 14, thereby causing the extension cylinder 14 to drive the sliding column 17 to slide on the inner wall of the extension cylinder 14.

[0022] In a preferred embodiment, the shape of the limiting block 19 is adapted to the shape of the inner wall of the limiting groove 18, and the limiting block 19 is located on the inner wall of the limiting groove 18.

[0023] In the above structure, the limiting block 19 is located on the inner wall of the limiting groove 18, so that the limiting block 19 can only slide on the inner wall of the limiting groove 18 when sliding, thereby limiting the limiting block 19 and preventing it from tilting when moving. At the same time, the sliding column 17 is limited, thereby preventing the sliding column 17 from rotating when moving.

[0024] In a preferred embodiment, the shape of the pin 11 is adapted to the shape of the inner wall of the cutter 12, and the pin 11 and the inner wall of the cutter 12 are positioned correspondingly.

[0025] In the above structure, the sliding column 17 moves toward the cutter 12, causing the sliding column 17 to drive the pin 11 to move toward the cutter 12, thereby causing the pin 11 to enter the inner wall of the cutter 12, so that the cutter 12 is fixed to the inner wall of the output shaft of the rotating motor 2.

[0026] In a preferred embodiment, the outer wall shape of the anti-rotation sleeve 15 is adapted to the inner wall shape of the extension cylinder 14, and the inner wall shape of the anti-rotation sleeve 15 is adapted to the shape of the threaded post 16.

[0027] In the above structure, by inserting the anti-rotation sleeve 15 between the threaded post 16 and the extension cylinder 14, the friction between the anti-rotation sleeve 15 and the threaded post 16 and the extension cylinder 14 is increased, thereby fixing the threaded post 16 and preventing the threaded post 16 from rotating.

[0028] Working Principle: When the equipment is in use, the built-in spring swings the rotating motor 2, causing it to move the external protective sleeve 6 and the cutter 12 towards the gear. The cutter 12 then performs a chamfering process on the gear. As the wear of the cutter 12 increases, the required swing angle increases. At this time, the swing angle is amplified by the swing arm 7 outside the rotating motor 2. Simultaneously, the swing arm 7 moves its external electrode plate 8, causing it to move towards the electrode plate 8 outside the trigger sensor 9. When the two electrode plates 8 are in contact, it indicates that the wear of the cutter 12 is significant, triggering the trigger sensor 9. This trigger sensor 9 then sends an electrical signal to controller 2 10. Controller 2 10 is electrically connected to controller 1 3. Simultaneously, through controller 1... The electrical connection between the trigger sensor 9 and the alarm 4 causes the trigger sensor 9 to send an electrical signal to the controller 10 when triggered, which in turn causes the controller 10 to send an electrical signal to the controller 3, causing the controller 3 to activate the alarm 4, which then alerts the staff. When the tool 12 needs to be replaced, the anti-rotation sleeve 15 is removed, and the threaded column 16 is rotated, causing the threaded column 16 to rotate on the inner wall of the extension cylinder 14 through the threaded connection with the extension cylinder 14. This causes the extension cylinder 14 to drive the sliding column 17 to slide on the inner wall of the extension cylinder 14, thereby causing the pin 11 to separate from the inner wall of the tool 12, and the fixing relationship of the tool 12 to disappear. At this time, the tool 12 is pulled outward, causing the tool 12 to be pulled out from the output shaft of the rotating motor 2.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
