Technical Field

[0002] Air hammer is a kind of free forging machine. The compression cylinder compresses the air and sends it into the working cylinder through the distribution valve (rotary valve), pushing the piston and the hammer head to move up and down to perform hammering. It is flexible to operate and is widely used in the production of small and medium-sized forgings. It is suitable for various free forgings, such as stretching, upsetting, punching, shearing, forging welding, twisting or bending, etc. Various open die forgings can be performed using a cushion die.

[0033] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] The embodiment of the present invention provides a hammering device for metal processing, such as Figure 1-13 As shown, the hammering device for metal processing includes: an air hammer body 1 and a working cylinder 2 and a lower base 4 fixedly mounted on the air hammer body 1, wherein the working cylinder 2 and the lower base 4 are located on the same longitudinal line, and the lower base 4 is located below the working cylinder 2; an upper anvil 3 is fixedly mounted on the output rod of the working cylinder 2, and a lower anvil 5 corresponding to the upper anvil 3 is fixedly mounted on the top of the lower base 4, and the upper anvil 3 and the lower anvil 5 are used to cooperate in hammering metal; a debris collecting bucket 6, wherein the debris collecting bucket 6 is fixedly sleeved on the lower base 4 and located outside the lower anvil 5, and is used to collect debris splashed during hammering; a power transmission mechanism, wherein the power transmission mechanism is arranged on the air hammer body 1 and is used to drive the working cylinder 2; a hammering vibration stabilizing mechanism, wherein the hammering vibration stabilizing mechanism is arranged on the upper anvil 3 and the debris collecting bucket 6, and is used to stabilize the workpiece during hammering.

[0035] In this embodiment, when in use, first ensure that the air hammer body 1 is firmly placed, and start the working cylinder 2. The output rod of the working cylinder 2 drives the upper anvil 3 to move up and down, and cooperates with the lower anvil 5 fixed on the top of the lower base 4 to perform hammering processing on the metal workpiece placed between the two. In this process, the debris generated by the hammering will be splashed into the surrounding debris collection bucket 6, which will be effectively collected by the debris collection bucket 6, avoiding the pollution of the processing environment caused by the scattering of debris. At the same time, in order to stabilize the vibration of the long workpiece during the hammering process, a hammering vibration stabilization mechanism arranged on the upper anvil 3 and / or the debris collection bucket 6 is used to assist in clamping and supporting the workpiece, reduce the vibration amplitude of the workpiece, improve the processing accuracy and protect the safety of the operator, wherein the hammering vibration stabilization mechanism is arranged on the rear side of the upper anvil 3 and the lower anvil 5, and can fix the tail section of the workpiece.

[0036] The present invention cleverly solves the problem of debris splashing and poor processing environment during the processing of the traditional air hammer by providing a debris collection bucket 6. The design of the debris collection bucket 6 enables the splashing debris to be collected promptly and effectively, which not only reduces the cleaning work of the working area, but also improves the processing environment, which is conducive to keeping the working area clean and safe.

[0037] In order to solve the problem that long workpieces are prone to vibration and difficult to stabilize during the hammering process, the present invention introduces a hammering vibration stabilization mechanism. This mechanism can be set on the rear side of the upper anvil 3, the debris collection bucket 6 or other suitable positions according to actual needs, and significantly reduce the vibration amplitude of the workpiece during the hammering process through physical support. This not only helps to improve processing accuracy, but also reduces damage to the operator's hands caused by workpiece vibration, increases work safety, reduces operator fatigue, and effectively prevents the workpiece from falling off during processing.

[0038] In a further preferred embodiment of the present invention, the upper surface of the lower anvil 5 is larger than the lower surface of the upper anvil 3, one side of the top of the debris collection bucket 6 is higher than the upper surface height of the lower anvil 5, and the other side is lower than the upper surface of the lower anvil 5, and the lower side is used to place the workpiece.

[0039] In this embodiment, the upper surface area of ​​the lower anvil 5 is larger than the lower surface area of ​​the upper anvil 3. This design helps to support the workpiece more stably and prevent the workpiece from slipping or shifting during the hammering process. At the same time, the top shape of the debris collection bucket 6 is also specially designed, with one side higher than the upper surface height of the lower anvil 5 and the other side lower than the upper surface of the lower anvil 5, forming an inclined opening. During the processing, the operator can easily put the workpiece onto the lower anvil 5 from the lower side of the top of the debris collection bucket 6, which is convenient and safe to operate.

[0040] Then, the working cylinder 2 is started, and the upper anvil 3 moves up and down under the drive of the output rod, and cooperates with the lower anvil 5 to hammer the workpiece. Due to the design of the debris collection bucket 6, the flying debris will be naturally guided into the collection bucket, especially those flying debris can also be blocked by the high side and fall into the bucket, while the low side ensures the smooth placement of the workpiece, where the low side is located at the front side of the operation, and the rest of the positions are high sides.

[0041] In a further preferred embodiment of the present invention, the power transmission mechanism includes a power spindle 7, a belt pulley 8, a motor seat 9, a power motor 10, a pulley 11 and a synchronous belt 12. The power spindle 7 is rotatably mounted on one side of the air hammer body 1 to drive the working cylinder 2 to move. The belt pulley 8 is fixedly mounted on the power spindle 7. The motor seat 9 is arranged on one side of the air hammer body 1. The power motor 10 is fixedly mounted on the motor seat 9. The pulley 11 is fixedly mounted on the output shaft of the power motor 10. The synchronous belt 12 is sleeved on the belt pulley 8 and the pulley 11.

[0042] In this embodiment, first, the power spindle 7 is firmly rotatably mounted on one side of the air hammer body 1, and as the core component of the entire power transmission system, it is responsible for driving the working cylinder 2 to move. Subsequently, the belt pulley 8 is fixedly sleeved on the power spindle 7 as the starting point of power transmission.

[0043] The motor seat 9 is set at an appropriate position of the air hammer body 1 to ensure the stable installation of the power motor 10. The power motor 10 is fixed to the motor seat 9 by bolts or other fastening methods, and a pulley 11 is fixedly installed on its output shaft. Next, the synchronous belt 12 is sleeved between the belt pulley 8 and the pulley 11 to form a tight power transmission link.

[0044] When the power motor 10 is started, its output shaft drives the pulley 11 to rotate, and then transmits power to the belt pulley 8 through the synchronous belt 12, and finally drives the power spindle 7 to rotate. The rotation of the power spindle 7 further drives the working cylinder 2 to move up and down, thereby realizing the hammering processing of the workpiece.

[0045] In a further preferred embodiment of the present invention, the hammer vibration stabilizing mechanism includes an upper pressing mechanism, a lower supporting mechanism and a connecting mechanism, the connecting mechanism is used to connect the upper pressing mechanism and the lower supporting mechanism so that they can cooperate synchronously to stabilize the hammered workpiece, the upper pressing mechanism includes a lifting plate 13, a lifting frame 14, a T-shaped guide seat 15, an upper stabilizing pressure plate 16 and a retaining spring 17, the lifting plate 13 is detachably fixedly mounted on one side of the upper anvil 3, the lifting frame 14 is fixedly mounted on the bottom of the lifting plate 13 and is located on the side of the upper anvil 3, the T-shaped guide seat 15 is slidably mounted on the bottom of the lifting frame 14, the upper stabilizing pressure plate 16 is fixedly mounted on the bottom of the T-shaped guide seat 15 and is located below the lifting frame 14, the upper stabilizing pressure plate 16 is lower than the lower side of the upper anvil 3 when stationary, and the retaining spring 17 is fixedly mounted on the top of the T-shaped guide seat 15 and on the top inner wall of the lifting frame 14.

[0046] In this embodiment, when the hammer vibration stabilization mechanism is used, the hanging plate 13 is firstly detachably fixedly mounted on one side of the upper anvil 3 to ensure that the hanging frame 14 is firmly located on the side of the upper anvil 3 .

[0047] Before the hammering operation begins, the upper stabilizing platen 16 is kept at a position lower than the lower side of the upper anvil 3 by maintaining the preload of the spring 17. When the workpiece is placed above the lower anvil 5 and the working cylinder 2 is started to drive the upper anvil 3 to descend for hammering, first, the upper stabilizing platen 16 located at a lower position will contact the workpiece. When the upper anvil 3 and the upper stabilizing platen 16 continue to descend, the upper stabilizing platen 16 pushes the T-shaped guide seat 15 upward and compresses the holding spring 17, and cooperates with the lower support mechanism to achieve stability of the upper part of the workpiece. When the working cylinder 2 contracts and drives the upper anvil 3 to move upward, the upper stabilizing platen 16 gradually separates from the workpiece, and the holding spring 17 expands and resets the T-shaped guide seat 15.

[0048] The hammer vibration stabilization mechanism effectively reduces the deviation and shaking of long workpieces caused by vibration during hammering through the synchronous cooperation of the upper pressure mechanism and the lower support mechanism, and significantly improves the stability of the workpiece. This not only helps to improve processing accuracy, but also protects the workpiece from unnecessary damage.

[0049] Since the workpiece is effectively stabilized during the hammering process, the operator can focus more on the hammering operation itself without having to worry about the potential safety hazards caused by the workpiece falling off or shifting. This helps reduce operational risks and improve workplace safety.

[0050] In a further preferred embodiment of the present invention, the lower support mechanism includes a support shaft 18, a lower stabilizing support plate 19, a diagonal support plate 20 and a retaining spring 21. The support shaft 18 is fixedly installed in the debris collection bucket 6. The support shaft 18 is located below the upper stabilizing pressure plate 16 and on one side of the lower anvil 5. The lower stabilizing support plate 19 is hingedly installed on the support shaft 18. When the lower stabilizing support plate 19 is horizontal, the top is consistent in height with the top of the lower anvil 5, and is used to cooperate with the upper stabilizing pressure plate 16 to stabilize the workpiece. The diagonal support plate 20 is arranged below the lower stabilizing support plate 19 and fixedly connected to the inner wall of the debris collection bucket 6. The retaining spring 21 is fixedly installed between the lower stabilizing support plate 19 and the diagonal support plate 20, and is used to reset the lower stabilizing support plate 19 to an inclined state.

[0051] In this embodiment, the lower support mechanism is an important component of the hammer vibration stabilization mechanism. First, the support shaft 18 is fixedly installed in the debris collection bucket 6 and is located below the upper stabilization pressure plate 16 and on one side of the lower anvil 5. In this way, the lower stabilization support plate 19 can be hingedly installed around the support shaft 18 to form a movable support surface.

[0052] When the workpiece is placed on the lower anvil 5 and is ready to be hammered, as the lifting plate 13 and the upper stabilizing plate 16 move downward, the lower stabilizing support plate 19 will be gradually adjusted to a horizontal state until the upper stabilizing plate 16 and the lower stabilizing support plate 19 completely clamp the workpiece. At this time, the top of the lower stabilizing support plate 19 is at the same height as the top of the lower anvil 5, and the workpiece is stably supported from both the upper and lower sides, which can maintain the stable position of the workpiece and prevent it from shifting due to vibration.

[0053] When the hammering action is completed, the working cylinder 2 drives the upper anvil 3 to move upward, and the upper stabilizing plate 16 gradually separates from the workpiece. At this time, the retaining spring 21 starts to play a role, and it uses its own elastic force to reset the lower stabilizing support plate 19 from a horizontal state to an inclined state, so as to prepare for the next workpiece support, and also drops the debris remaining on the upper side into the debris collection bucket 6.

[0054] In a further preferred embodiment of the present invention, the connecting mechanism includes a belt-threading seat 22 and a connecting steel belt 23, the belt-threading seat 22 is fixedly mounted on the lifting plate 13, the connecting steel belt 23 is slidably installed on the belt-threading seat 22 and is positioned by bolts, one end of the connecting steel belt 23 is fixedly connected to the lower stable support plate 19, and is used to pull the lower stable support plate 19 to deflect upward when the lifting plate 13 moves downward.

[0055] In this embodiment, the connecting mechanism serves as a bridge between the upper pressing mechanism and the lower supporting mechanism, and plays an important role in coordinating the actions of the two. Specifically, the belt threading seat 22 is fixedly installed on the hanging plate 13, serving as a support and guide point for the connecting steel belt 23. The connecting steel belt 23 is slidably installed in the belt threading seat 22, and is positioned by bolts to ensure that it is stably and adjustably connected between the hanging plate 13 and the lower stable support plate 19. Since the thickness of each workpiece is different, and the upper stable pressing plate 16 adopts a retaining spring 17 with a limit, it is necessary to adjust the length of the connecting steel belt 23 to adapt.

[0056] When the hoisting plate 13 moves downward as driven by the working cylinder 2, the connecting steel belt 23 is pulled accordingly. Since one end of the connecting steel belt 23 is fixedly connected to the lower stable support plate 19, during the downward movement, the connecting steel belt 23 will exert an upward pulling force on the lower stable support plate 19, causing it to gradually deflect upward and tend to a horizontal state. In this way, as the hoisting plate 13 continues to move downward, the upper stable pressure plate 16 and the lower stable support plate 19 can synchronously clamp the workpiece stably.

[0057] The design of the belt-threading seat 22 and the connecting steel belt 23 realizes a close connection and synchronous action between the upper pressing mechanism and the lower supporting mechanism. This design ensures that the upper stable pressing plate 16 and the lower stable supporting plate 19 can stably clamp the workpiece during the hammering process, thereby improving the processing accuracy and stability.

[0058] The sliding through installation and bolt positioning design of the connecting steel belt 23 allow the operator to adjust the length and position of the connecting steel belt 23 according to actual needs to adapt to workpieces of different sizes and shapes. This flexibility not only improves the convenience of operation, but also enhances the adaptability and reliability of the equipment.

[0059] The upper pressing mechanism and the lower supporting mechanism are organically combined through the connecting mechanism, optimizing the overall structural layout. This design not only reduces the number and complexity of parts, but also improves the overall stability and durability of the equipment. At the same time, it is also convenient for subsequent maintenance and upkeep.

[0060] In a further preferred embodiment of the present invention, a balancing limit strip 24 is fixedly installed in the debris collection bucket 6, and the bottom of the balancing limit strip 24 is located at the same horizontal plane as the top of the lower anvil 5, which is used to resist the limiting lower stabilizing support plate 19.

[0061] In this embodiment, a balancing limit strip 24 is fixedly installed inside the debris collection bucket 6. The bottom of the balancing limit strip 24 is located at the same horizontal plane as the top of the lower anvil 5. When the hoisting plate 13 drives the upper stabilizing plate 16 to move downward and pulls the lower stabilizing support plate 19 to deflect upward through the connecting steel belt 23, the lower stabilizing support plate 19 will gradually approach the balancing limit strip 24. Once the lower stabilizing support plate 19 contacts the balancing limit strip 24, the lower stabilizing support plate 19 will rotate to the limit to prevent the lower stabilizing support plate 19 from rotating excessively.

[0062] In a further preferred embodiment of the present invention, belt guide rollers 25 are fixedly installed on the air hammer body 1 and in the debris collection bucket 6 , and the connecting steel belt 23 passes around the two belt guide rollers 25 .

[0063] In this embodiment, in order to improve the guiding property and running stability of the connecting steel belt 23, belt guide rollers 25 are fixedly installed on the air hammer body 1 and inside the debris collection bucket 6. The two belt guide rollers 25 serve as guide devices for the connecting steel belt 23, so that the connecting steel belt 23 can bypass them to form a smoother transmission path.

[0064] When the hoisting plate 13 moves downward with the driving of the working cylinder 2, the connecting steel belt 23 is gradually tightened. Due to the existence of the belt guide roller 25, the connecting steel belt 23 can move smoothly along the preset path, while transmitting the pulling force to the lower stable support plate 19, causing it to gradually deflect upward. In this process, the belt guide roller 25 effectively reduces the friction and wear between the connecting steel belt 23 and the air hammer body 1 and the debris collection bucket 6, thereby extending the service life of the connecting steel belt 23.

[0065] In a further preferred embodiment of the present invention, the length of the lower stabilizing support plate 19 is greater than the length of the upper stabilizing pressure plate 16 , and the balancing limit strip 24 is staggered from the upper stabilizing pressure plate 16 .

[0066] In this embodiment, in order to optimize the stability and adaptability of workpiece clamping, the length of the lower stable support plate 19 is designed to be greater than the length of the upper stable pressure plate 16. At the same time, the balancing limit strip 24 is staggered from the upper stable pressure plate 16 to ensure that it does not affect the normal operation of the upper stable pressure plate 16, while effectively limiting the lower stable support plate 19.

[0067] When the equipment processes the workpiece, the hoisting plate 13 drives the upper stabilizing plate 16 to move downward, and the connecting steel belt 23 pulls the lower stabilizing support plate 19 to deflect upward. Since the lower stabilizing support plate 19 is longer, it can support the workpiece more comprehensively, especially when the workpiece is long or irregular in shape, this design can provide a more stable support environment. At the same time, the staggered setting of the balance limit strip 24 and the upper stabilizing plate 16 ensures that the upper stabilizing plate 16 can move downward freely and accurately press the workpiece.

[0068] In a further preferred embodiment of the present invention, a connecting rod mechanism, a compression cylinder, and a rotary valve are provided in the air hammer body 1, the power spindle 7 is used to drive the connecting rod mechanism to rotate, the connecting rod mechanism is used to drive the compression piston of the compression cylinder to reciprocate, the rotary valve is arranged between the compression cylinder and the working cylinder 2, and an operating rod for controlling the rotary valve is provided on the air hammer body 1.

[0069] In this embodiment, the power spindle 7 serves as the core power source of the entire air hammer. The power spindle 7 is usually made of high-strength alloy steel to ensure sufficient rigidity and stability during high-speed rotation.

[0070] The connecting rod mechanism is a key component that connects the power spindle 7 and the compression cylinder. It is responsible for converting the rotational motion of the power spindle 7 into the linear reciprocating motion of the compression piston. The connecting rod mechanism is usually composed of multiple connecting rods, crankshafts, bearings and other components. These components are precisely processed and assembled to ensure the accuracy and reliability of the movement. Driven by the power spindle 7, the connecting rod mechanism uses its complex kinematic principles to enable the compression piston to perform efficient and stable reciprocating motion in the compression cylinder.

[0071] The compression cylinder is a key component for producing high-pressure gas. It is usually composed of a high-strength cylinder, a piston, and seals. Driven by the connecting rod mechanism, the compression piston reciprocates in the compression cylinder to compress and release the gas in the cylinder. As the piston reciprocates, the gas pressure in the cylinder continues to increase, providing sufficient power for the subsequent hammering action.

[0072] The rotary valve is a key component for controlling the flow direction and flow of high-pressure gas. It is located between the compression cylinder and the working cylinder 2. The rotary valve is equipped with complex flow channels and valve mechanisms. The opening degree and switch state of the valve are adjusted by the rotation of the operating rod, thereby controlling the flow and pressure of high-pressure gas from the compression cylinder to the working cylinder 2.

[0073] The operating lever is an external operating component for controlling the rotary valve, and is usually arranged in a conspicuous position on the air hammer body 1 for the convenience of the operator to operate. The operating lever is connected to the valve mechanism inside the rotary valve through a mechanical connection, and the operator controls the opening degree and switch state of the rotary valve by rotating or pushing and pulling the operating lever.

[0074] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0075] In another embodiment of the present invention, the air hammer body 1 is provided with a drainage mechanism, and the drainage mechanism includes a drainage tube 26, a suction pipe 27, a high-speed shaft 28, a plurality of blades 29, an extension shaft 30, a power reversing shaft 31, two bevel gears 32, two synchronous sprockets 33 and a synchronous chain 34. The drainage tube 26 is fixedly installed on the air hammer body 1, the suction pipe 27 is connected to the debris collection bucket 6 and the drainage tube 26, the high-speed shaft 28 is rotatably installed in the drainage tube 26, and the plurality of blades 29 are fixedly installed. It is installed on the high-speed rotating shaft 28 and located in the drainage tube 26, the extension shaft 30 is fixedly installed on one end of the high-speed rotating shaft 28, the power reversing shaft 31 is rotatably installed on one side of the air hammer body 1, the two bevel gears 32 are fixedly sleeved on the extension shaft 30 and the power reversing shaft 31 respectively, the two bevel gears 32 are meshed with each other, the two synchronous sprockets 33 are fixedly sleeved on the power reversing shaft 31 and the power main shaft 7 respectively, and the synchronous chain 34 is sleeved on the two synchronous sprockets 33.

[0076] In the above embodiment, a debris collecting port 54 is provided on the air hammer body 1, and a debris collecting bag 55 is detachably installed in the debris collecting port 54. A debris discharge pipe 56 is fixedly installed at the bottom of the drainage tube 26, and the bottom end of the debris discharge pipe 56 extends into the debris collecting port 54 and is inserted into the debris collecting bag 55.

[0077] In this embodiment, the drainage tube 26 is used as a preliminary collection container for debris, and is connected to the debris collection bucket 6 through the suction pipe 27 to suck the debris generated during the processing. The high-speed rotating shaft 28 rotates in the drainage tube 26, driving the multiple blades 29 fixed thereon to generate suction, further enhancing the suction effect of the debris. At the same time, the high-speed rotating shaft 28 is connected to the power main shaft 7 through the transmission chain of the extension shaft 30, the power reversing shaft 31, the bevel gear 1 32, the synchronous sprocket 1 33 and the synchronous chain 1 34, realizing the synchronous operation with the main working cycle of the air hammer without the need for an additional power source. Specifically, when the power motor 10 drives the power main shaft 7 to rotate, the synchronous sprocket 1 33 and the synchronous chain 1 34 are used to drive the power reversing shaft 31 to rotate, and the power reversing shaft 31 drives the extension shaft 30 to rotate through the bevel gear 1 32.

[0078] After the debris collection is completed, the debris in the drainage tube 26 is discharged into the debris collection bag 55 in the debris collection port 54 opened on the air hammer body 1 through the debris discharge pipe 56, thereby realizing the centralized collection and treatment of the debris. The debris collection bag 55 is detachable, which is convenient for users to replace and clean at any time.

[0079] In another embodiment of the present invention, a scraping mechanism is provided on the lower base 4 for scraping off debris in the debris collecting bucket 6. An annular assembly groove 35 is provided above the lower base 4. The scraping mechanism includes an annular track 36, a rotating ring 37, a connecting block 38, a scraping plate 39 and a power transmission mechanism. The annular track 36 is fixedly installed in the annular assembly groove 35. The rotating ring 37 is rotatably sleeved on the annular track 36. The connecting block 38 is fixedly installed on the outer side of the rotating ring 37. The scraping plate 39 is fixedly installed on the connecting block 38. The scraping plate 39 is in contact with the inner wall of the debris collecting bucket 6 and the outer side of the lower base 4. The lower base 4 is cylindrical.

[0080] In this embodiment, the scraping mechanism is installed on the lower base 4, and the connection block 38 and the scraping plate 39 fixed thereon are driven to move along the inner wall of the debris collection bucket 6 by the stable rotation of the rotating ring 37 on the annular track 36. Specifically, an annular assembly groove 35 is designed above the lower base 4, and the annular track 36 is fixedly installed thereon, and the rotating ring 37 is tightly sleeved on the annular track 36, so that the rotating ring 37 can rotate smoothly. The connecting block 38 is fixed on the outer side of the rotating ring 37, and the scraping plate 39 is fixedly installed on the connecting block 38, ensuring that the scraping plate 39 is in close contact with the inner wall of the debris collection bucket 6.

[0081] The power transmission mechanism is responsible for providing stable rotational power to the rotating ring 37, so that it can continuously and effectively perform scraping operations. The scraping mechanism continuously scrapes away the debris in the debris collection bucket 6, preventing the debris from accumulating and agglomerating in the bucket, thereby improving the efficiency of debris collection and facilitating suction by the drainage mechanism.

[0082] In another embodiment of the present invention, the power transmission mechanism includes a toothed ring 40 fixedly installed in the rotating ring 37, a power transmission groove 41 is provided on one side of the annular assembly groove 35, a driving gear 42 is rotatably installed in the power transmission groove 41, and the driving gear 42 is meshed with the toothed ring 40, a power cavity 43 is provided on the lower base 4, a transmission avoidance groove 44 is provided on the inner wall of one side of the power cavity 43, an assembly hole 45 is provided between the transmission avoidance groove 44 and the power transmission groove 41, a longitudinal shaft 1 46 is rotatably installed in the power cavity 43, a longitudinal shaft 2 47 is rotatably installed in the assembly hole 45, the top end of the longitudinal shaft 2 47 extends into the power transmission groove 41 and is fixedly connected to the bottom of the driving gear 42, and the bottom end of the longitudinal shaft 2 47 extends to the transmission cavity 43. In the dynamic avoidance groove 44, a synchronous sprocket 2 48 is fixedly installed on the longitudinal axis 1 46 and the bottom end of the longitudinal axis 2 47, and the two synchronous sprockets 2 48 are sleeved with the same synchronous chain 2 49, and the synchronous chain 2 49 is located in the power cavity 43 and the transmission avoidance groove 44. A synchronous shaft 50 is rotatably installed in the power cavity 43, and both ends of the synchronous shaft 50 extend to the outside of the lower base 4. The synchronous shaft 50 is located below the debris collection bucket 6 and the longitudinal axis 1 46, and a bevel gear 2 51 is fixedly installed on the synchronous shaft 50 and the bottom end of the longitudinal axis 1 46, and the two bevel gears 2 51 are meshed with each other. A synchronous sprocket 3 52 is fixedly installed on the same end of the synchronous shaft 50 and the high-speed rotating shaft 28, and the two synchronous sprockets 3 52 are sleeved with the same synchronous chain 3 53.

[0083] In this embodiment, when the power motor 10 drives the power main shaft 7 to rotate, the synchronous sprocket 1 33 and the synchronous chain 1 34 are used to drive the power reversing shaft 31 to rotate, and the power reversing shaft 31 drives the extension shaft 30 to rotate through the bevel gear 1 32. The extension shaft 30 uses the synchronous sprocket 3 52 and the synchronous chain 3 53 to drive the synchronous shaft 50. The synchronous shaft 50 starts to rotate after receiving the power. Since both ends of the synchronous shaft 50 extend outside the lower base 4 and are fixedly sleeved with the bevel gear 2 51, its rotation will drive the bevel gear 2 51 to rotate together, and the two bevel gears 2 51 are meshed, one of which is fixed on the synchronous shaft 50, and the other is fixed on the bottom end of the longitudinal shaft 1 46. Through the meshing transmission of the bevel gear 2 51, the power is transmitted to the longitudinal shaft 1 46, so that it also starts to rotate; the bottom ends of the longitudinal shaft 1 46 and the longitudinal shaft 2 47 are fixedly installed with a synchronous sprocket 2 48, so when the longitudinal shaft 1 46 rotates, the longitudinal shaft 2 47 will be driven to rotate synchronously through the synchronous chain 2 49, and the rotation of the longitudinal shaft 2 47 will drive the driving gear 42 to rotate together; the driving gear 42 is meshed with the toothed ring 40 in the rotating ring 37. When the driving gear 42 rotates, the power is transmitted to the toothed ring 40 through the gear meshing transmission, and then the rotating ring 37 is driven to rotate on the annular track 36. The rotation of the rotating ring 37 drives the scraper plate 39 to move along the inner wall of the debris collection bucket 6 through the connecting block 38. Since the scraper plate 39 is in close contact with the inner wall of the debris collection bucket 6, the debris in the bucket can be effectively scraped and collected.

[0084] Synchronization and air hammer working cycle: A synchronization sprocket 3 52 is fixedly mounted on the same end of the synchronization shaft 50 and the high-speed rotating shaft 28, and is connected by a synchronization chain 3 53. In this way, the rotation of the scraping mechanism is synchronized with the main working cycle of the air hammer, ensuring the timeliness and effectiveness of the scraping operation.

[0085] In summary, the scraping mechanism transmits the power of the power source to the rotating ring 37 through a series of precise mechanical transmission devices, thereby driving the scraping plate 39 to move along the inner wall of the debris collection bucket 6 to scrape and collect the debris. At the same time, the timeliness and efficiency of the scraping operation are ensured through the synchronous design with the main working cycle of the air hammer.

[0086] To sum up, compared with the relevant technology, the device adopts a hammer vibration stabilization mechanism to assist in clamping and supporting the workpiece, reduce the vibration amplitude of the workpiece, improve the processing accuracy and protect the safety of the operator. By setting a debris collection bucket 6, the problem of debris splashing and poor processing environment during the processing of the traditional air hammer is solved, so that the splashing debris can be collected in time and effectively, which not only reduces the cleaning work of the working area, but also improves the processing environment, which is conducive to keeping the working area clean and safe.
