Technical Field

[0001] The invention relates to the technical field of pneumatic hammer devices, and in particular to a high-speed impact hammer device. Background Art

[0002] In production practice, we often encounter certain tasks that require greater impact force or impact work to complete. Stamping equipment has a complex structure, large size, weak mobility, and large operating space, which is not suitable for certain special occasions. The air-controlled valve vibration impact device is an impact device that converts the pressure energy of compressed air into the kinetic energy of the high-speed movement of the piston and piston rod, thereby generating a greater impact force to strike the workpiece to do work.

[0003] The prior art with announcement number CN202811640U discloses an impact cylinder, including a cylinder, the cylinder including a gas pressure front cover and a gas pressure rear cover, a piston is matched and arranged in the cylinder, one end of the piston is connected to a piston rod, and the other end is connected to a sealing seat, a conical air flow port is arranged in the sealing seat, and the diameter of the conical air flow port close to the piston end is smaller than the diameter of the end away from the piston. The compressed gas is compressed and works in the conical air flow port, generating a strong thrust, thereby pushing the piston to move at a high speed, driving the piston rod to impact and press the object.

[0004] However, the prior art still has defects. For example, the impact cylinder does not have a structure for controlling the movement of the piston, and the movement of the piston cannot be flexibly controlled according to needs, so as to hammer the target object at an appropriate time point. Summary of the invention

[0005] In view of this, it is necessary to provide a high-speed impact hammer device to solve the technical problem that the impact cylinder in the prior art has no structure for controlling the movement of the piston and cannot flexibly control the movement of the piston as needed, thereby hammering the target object at the appropriate time.

[0006] In order to achieve the above technical objectives, the technical solution of the present invention provides a high-speed impact hammer device, comprising:

[0007] The housing is provided with a first air inlet passage, a second air inlet passage and a transfer chamber, wherein the first air inlet passage is connected to the second air inlet passage and the transfer chamber;

[0008] A hammer assembly, comprising a fixed cylinder and a hammer sliding member, wherein the fixed cylinder is connected to the housing and is located in the transfer chamber, and the hammer sliding member is slidably connected to the inner wall of the fixed cylinder;

[0009] An airflow control component includes an air pressure control plug and an opening and closing plug. The air pressure control plug is slidably connected to the shell and can seal and abut against or detach from the fixed cylinder when sliding. The air pressure control plug is connected to the second air intake channel and can abut against the fixed cylinder under the air pressure of the second air intake channel, and can also detach from the fixed cylinder under the action of the air pressure in the transfer chamber; the opening and closing plug is slidably connected to the shell and can slidably block or open the second air intake channel. When the opening and closing plug slides to open the second air intake channel, the air pressure control plug abuts against the fixed cylinder under the action of the air pressure in the second air intake channel; when the opening and closing plug slides to block the second air intake channel, the boosted air pressure in the transfer chamber can drive the air pressure control plug to slide away from the fixed cylinder, and can drive the hammer sliding member to slide through air pressure to hammer external objects.

[0010] Furthermore, the airflow control assembly also includes a return spring, which is connected to the air pressure control plug. When the opening and closing plug opens the second air intake channel, the air pressure of the second air intake channel and the elastic force of the return spring jointly drive the air pressure control plug to seal against the fixed cylinder; when the opening and closing plug closes the second air intake channel, the air pressure in the transfer chamber drives the air pressure control plug to separate from the fixed cylinder and compress the return spring.

[0011] Furthermore, the shell is also provided with an air flow storage chamber, the fixed cylinder is provided with an air inlet and an air outlet, the air inlet and the air outlet are both connected to the storage chamber and the interior of the fixed cylinder, the hammer sliding member includes a slider and a connecting rod, the slider is sealingly and slidably connected to the inner wall of the fixed cylinder, the connecting rod and the inner wall of the fixed cylinder are spaced to form a reverse thrust space, when the slider slides to between the air inlet and the air outlet, the air flow inside the fixed cylinder flows into the storage chamber through the air inlet, and then flows out from the storage chamber through the air outlet to the reverse thrust space, driving the hammer sliding member to reset.

[0012] Furthermore, the air pressure control plug is provided with an exhaust channel, which connects the interior of the fixed cylinder with the external air. When the hammer sliding member slides toward the air pressure control plug to reset, the gas inside the fixed cylinder can be discharged to the external atmosphere through the exhaust channel.

[0013] Furthermore, a conical groove is formed on a side of the air pressure control plug facing the fixing cylinder, and the conical groove communicates with the exhaust passage and the interior of the fixing cylinder.

[0014] Furthermore, the hammer assembly also includes a positioning member, which is connected to the housing and is used to limit the sliding block when the hammer sliding member hammers an object.

[0015] Furthermore, the positioning member is provided with an inclined surface along its circumferential side, and when the hammer sliding member abuts against the positioning member, a reset preparation chamber is formed between the inclined surface, the hammer sliding member and the inner wall of the fixed cylinder, and the reset preparation chamber is connected to the air outlet.

[0016] Furthermore, the airflow control component also includes an elastic member, which is connected to the opening and closing plug. When the opening and closing plug blocks the second air intake channel, the opening and closing plug compresses the elastic member to accumulate elastic force, and the elastic member can release the elastic force to drive the opening and closing plug to slide to open the second air intake channel.

[0017] Furthermore, the airflow control component also includes a limit piece, which is connected to the shell and has a through hole. The opening and closing plug includes a main body, a first sealing ring and a control rod. One end of the main body is connected to the first sealing ring, and the other end is connected to the control rod. The control rod passes through the through hole and extends out of the shell. When the control rod is subjected to external force, it can drive the first sealing ring to block the second air intake channel. The elastic member can release elastic force to drive the main body to abut against the limit piece. When the main body abuts against the limit piece, the first sealing ring opens the second air intake channel.

[0018] Furthermore, the airflow control assembly also includes a driving cylinder and a telescopic rod, wherein the driving cylinder is connected to the telescopic rod and can drive the telescopic rod to press against the control rod or to separate from the control rod.

[0019] Compared with the prior art, the beneficial effects of the present invention include: in the preparatory stage, the opening and closing plug opens the second air inlet channel, and the first air inlet channel is used to connect to an external air source, and the first air inlet channel, the second air inlet channel and the transfer chamber are inflated at the same time by the external air source. At this time, the second air inlet channel has air pressure, which drives the air pressure control plug to seal against the fixed cylinder, and the hammer sliding part inside the fixed cylinder is in a stationary state. When the opening and closing plug blocks the second air inlet channel, the second air inlet channel releases pressure, and the air pressure in the transfer chamber drives the air pressure control plug to slide away from the fixed cylinder. The gas in the transfer chamber instantly enters the fixed cylinder and drives the hammer sliding part to slide quickly to hammer the external object. Therefore, when it is necessary to drive the hammer sliding part to hammer the external object, it is only necessary to control the opening and closing plug to block the second air inlet channel, and the operation is simple and convenient.

[0025] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0026] refer to Figure 1 The present invention provides a high-speed impact hammer device 100, which is used to automatically hammer a target object. An operator can control the impact hammer device 100 to hammer an object at a fixed point, which is easy to operate.

[0027] The high-speed impact hammer device 100 includes a housing 1, a hammer assembly 2 and an airflow control assembly, wherein the hammer assembly 2 and the airflow control assembly are both arranged in the housing 1, and the hammer assembly 2 can hammer the target object reciprocatingly under the control of the airflow control assembly.

[0028] The airflow control assembly includes a first control portion 31 and a second control portion 32 .

[0029] refer to Figure 2 The shell 1 is provided with a first air intake channel 11, a second air intake channel 12 and a transfer chamber 13. The first air intake channel 11 is connected to the second air intake channel 12 and the transfer chamber 13. The first air intake channel 11 is linear, one end of which is connected to the transfer chamber 13, and the other end is connected to the air intake valve 14. The air intake valve 14 is used to connect to an external air source so that the external air source can inflate and pressurize the first air intake channel 11 through the air intake valve 14. The second air intake channel 12 includes three linear channels arranged vertically in sequence, so that the second air intake channel 12 is Z-shaped. One end of the second air intake channel 12 is connected to the first control unit 31, and the other end is connected to the second control unit 32. The first control unit 31 is used to control whether the second air intake channel 12 is connected to the first air intake channel 11 or not. When the second air intake channel 12 is connected to the first air intake channel 11, the first air intake channel 11 can inflate the second air intake channel 12. When the second air intake passage 12 is not connected to the first air intake passage 11 , the first air intake passage 11 cannot inflate the second air intake passage 12 .

[0030] The diameter of the first air inlet channel 11 is greater than that of the second air inlet channel 12, so that the air intake efficiency of the transfer chamber 13 is greater than that of the second air inlet channel 12, which is convenient for instantly providing a larger air flow rate for the hammer assembly 2, so that the hammer assembly 2 can quickly hammer the object.

[0031] The housing 1 is also provided with a storage chamber 15, which is spaced apart from the transfer chamber 13. When the hammer assembly 2 completes a hammering, the storage chamber 15 can be inflated to drive the hammer assembly 2 to reset by air pressure, so as to prepare for the next hammering of the hammer assembly 2 to hammer an object.

[0032] The hammer assembly 2 includes a fixed cylinder 21 and a hammer slide 22. The fixed cylinder 21 is connected to the shell 1 and is located in the transfer chamber 13. During the entire working process, the fixed cylinder 21 remains fixed. The hammer slide 22 is slidably connected to the inner wall of the fixed cylinder 21. When the transfer chamber 13 and the fixed cylinder 21 are internally connected, the gas in the transfer chamber 13 will instantly flow into the fixed cylinder 21, pressurize the interior of the fixed cylinder 21, and drive the hammer slide 22 to slide in a direction away from the second control part 32 to hammer the object. When the hammer slide 22 completes a hammering, the storage chamber 15 can pressurize the hammer slide 22, drive the hammer slide 22 to automatically reset, and prepare for the next time the hammer assembly 2 hammers the object.

[0033] The fixed cylinder 21 is provided with an air inlet 211 and an air outlet 212, and the air inlet 211 is located between the second control unit 32 and the air outlet 212. The air inlet 211 and the air outlet 212 are both connected to the storage chamber 15 and the interior of the fixed cylinder 21. The air inlet 211 is used for the gas inside the fixed cylinder 21 to enter the storage chamber 15, and the air outlet 212 is used for the gas in the storage chamber 15 to flow out.

[0034] The hammering sliding member 22 includes a slider 221, a connecting rod 222, a hammer head 223 and a clamping block 224. The two ends of the connecting rod 222 are respectively connected to the slider 221 and the hammer head 223, and the two ends of the clamping block 224 are connected to the hammer head 223 and the connecting rod 222. The slider 221 is sealingly slidably connected to the inner wall of the fixed cylinder 21. When the slider 221 is subjected to the air pressure provided by the transfer chamber 13, the slider 221 drives the connecting rod 222 and the hammer head 223 to slide quickly, so that the hammer head 223 hammers the object.

[0035] The diameter of the connecting rod 222 is smaller than that of the slider 221, so that the connecting rod 222 and the inner wall of the fixed cylinder 21 are separated to form a reverse thrust space. When the hammer head 223 completes a hammering, the slider 221 slides to the limit position. At this time, the reverse thrust space is connected to the storage chamber 15, and the gas in the storage chamber 15 flows into the reverse thrust space, driving the hammering slider 22 to reset. When the block 224 abuts against the housing 1, the slider 221 resets to the limit position.

[0036] refer to Figure 3The housing 1 also has a positioning member 16, which is used to limit the slider 221. When the slider 221 abuts against the positioning member 16, the slider 221 slides to the limit position. The positioning member 16 has an inclined surface 161 along its circumferential side. When the slider 221 abuts against the positioning member 16, a reset preparation chamber 162 is formed between the inclined surface 161, the surface of the slider 221 and the inner wall of the fixed cylinder 21. The reset preparation chamber 162 is connected to the air outlet 212, so that the air flow of the storage chamber 15 can flow into the reset preparation chamber 162 through the air outlet 212. The air pressure drives the slider 221 to slide away from the positioning member 16, and the hammer slider 22 is reset. In this process, the air pressure in the reverse thrust space gradually increases, so that the speed of the hammer slider 22 resetting gradually increases.

[0037] refer to Figure 4 The first control unit 31 includes a first fixed block 311, a limiter 312, an elastic member 313 and an opening and closing plug 314. The first fixed block 311 and the limiter 312 are fixedly connected to the housing 1. The first fixed block 311 is penetrated by a transfer channel 315, and the transfer channel 315 is connected to the first air inlet channel 11 and the second air inlet channel 12. The elastic member 313 is located in the transfer channel 315, and the elastic member 313 does not affect the air flow of the transfer channel 315. One end of the elastic member 313 is connected to the bottom of the transfer channel 315, and the other end is connected to the opening and closing plug 314.

[0038] The opening and closing plug 314 includes a body 316, a first sealing ring 317, a pressure release sealing ring 80 and a control rod 318. One end of the body 316 is connected to the first sealing ring 317, and the other end is connected to the control rod 318, and the pressure release sealing ring 80 is sleeved. The body 316 is slidably connected to the limiter 312. During the sliding process, the body 316 can drive the first sealing ring 317 to block or open the transfer channel 315, and at the same time drive the pressure release sealing ring 80 to seal and connect to the limiter 312 or to separate from the limiter 312. When the body 316 slides toward the elastic member 313, the first sealing ring 317 blocks the transfer channel 315, the pressure release sealing ring 80 separates from the limiter 312, and the elastic member 313 is compressed by the body 316 to accumulate elastic force, so that the first air inlet channel 11 and the second air inlet channel 12 cannot be connected, and the second air inlet channel 12 is connected to the external atmosphere to release pressure.

[0039] The elastic member 313 can also release elastic force to drive the main body 316 to reset. During this process, the main body 316 drives the pressure release sealing ring 80 to reseal the connection limit member 312, and the second air intake channel 12 is isolated from the external atmosphere; at the same time, the main body 316 drives the first sealing ring 317 to open the transit channel 315, and the airflow of the first air intake channel 11 can enter the second air intake channel 12 through the transit channel 315. The other end of the second air intake channel 12 is connected to the second control part 32, so the airflow can be delivered to the second control part 32 to drive the second control part 32 to seal against the fixed cylinder 21.

[0040] The stopper 312 is provided with a through hole, and one end of the control rod 318 passes through the through hole and extends out of the housing 1. When subjected to an external force, the control rod 318 can slide toward the elastic member 313, driving the first sealing ring 317 to block the transfer channel 315, thereby blocking the second air inlet channel 12, and driving the pressure relief sealing ring 80 to separate from the stopper 312. In this process, the body 316 compresses the elastic member 313, driving the elastic member 313 to accumulate elastic force.

[0041] When the external force on the control rod 318 is removed, the elastic member 313 can release the elastic force to drive the main body 316 to slide away from the elastic member 313 until the main body 316 abuts against the limit member 312. At this time, the first sealing ring 317 opens the transfer channel 315, that is, opens the second air intake channel 12, and the pressure relief sealing ring 80 blocks the through hole, and the second air intake channel is isolated from the external air.

[0042] There are many ways to drive the control rod 318 to slide toward the elastic member 313, such as manually pressing the control rod 318, or automatically driving the control rod 318 to slide according to control instructions through a device such as a cylinder.

[0043] In one embodiment, the first control unit 31 further includes a driving cylinder 319 and a telescopic rod 320. The driving cylinder 319 is connected to the telescopic rod 320 and can drive the telescopic rod 320 to press against the control rod 318 or to separate from the control rod 318. When the telescopic rod 320 presses against the control rod 318, the second air inlet passage 12 can be blocked. When the telescopic rod 320 separates from the control rod 318, the second air inlet passage 12 is automatically opened. This automatic cylinder control method is not only convenient to control, but also conducive to improving work efficiency.

[0044] refer to Figure 5 The second control part 32 includes a second fixed block 321, an air pressure control plug 322, a second sealing ring 323, a return spring 324 and a sealing gasket 330, wherein the air pressure control plug 322 is slidably connected to the second fixed block 321, the two ends of the return spring 324 are connected to the second fixed block 321 and the air pressure control plug 322, and the second sealing ring 323 is connected to the side of the air pressure control plug 322 facing away from the second fixed block 321. The second fixed block 321 is sealed and fixedly connected to the housing 1 and does not move. The second fixed block 321 can be regarded as a part of the housing 1, so it can be understood that the air pressure control plug 322 is slidably connected to the housing 1. The air pressure control plug 322 can slide up and down along the second fixed block 321 to drive the second sealing ring 323 to seal against the fixed cylinder 21 or to separate from the fixed cylinder 21.

[0045] When the second sealing ring 323 seals against the fixed cylinder 21, the gas in the transfer chamber 13 cannot enter the fixed cylinder 21. If the cylinder 319 is driven to trigger the control rod 318 to slide, the air pressure space between the second fixed block 321 and the air pressure control plug 322 is connected to the outside air through the second air inlet channel 12, and the pressure is released. The air pressure in the transfer chamber 13 can drive the air pressure control plug 322 to slide toward the second fixed block 321 to separate from the fixed cylinder 21, and the gas in the transfer chamber 13 can instantly enter the fixed cylinder 21, driving the hammer sliding member 22 to slide quickly to hammer the object.

[0046] The air pressure control plug 322 is provided with an exhaust passage 325 along its thickness direction, the second fixed block 321 is provided with a first exhaust port 326, the housing 1 is provided with a second exhaust port 327, and the exhaust passage 325 is connected to the outside air through the first exhaust port 326 and the second exhaust port 327 in sequence. When the hammer slide 22 slides toward the air pressure control plug 322 to reset, the gas inside the fixed cylinder 21 can be discharged to the outside atmosphere through the exhaust passage 325, the first exhaust port 326 and the second exhaust port 327 in sequence, so that the hammer slide 22 can be reset smoothly and prepare for the next hammering of the object.

[0047] When the air pressure control plug 322 is separated from the fixed cylinder 21 and slides to abut the sealing gasket 330, the exhaust channel 325 is not connected to the first exhaust port 326, so that the gas in the transfer chamber 13 can flow into the fixed cylinder 21 more, which is used to drive the hammer sliding member 22 to slide quickly and hammer the object. When the air pressure control plug 322 is sealed against the fixed cylinder 21, the two ends of the exhaust channel 325 are respectively connected to the inside of the fixed cylinder 21 and the first exhaust port 326, so that the gas inside the fixed cylinder 21 can be discharged to the outside atmosphere through the exhaust channel 325, the first exhaust port 326 and the second exhaust port 327.

[0048] In one embodiment, a conical groove 328 may be provided on the side of the air pressure control plug 322 facing the fixed cylinder 21, and the conical groove 328 is connected to the exhaust passage 325 and the interior of the fixed cylinder 21. Since the side with a larger area of ​​the conical groove 328 is connected to the interior of the fixed cylinder 21, when the hammer sliding member 22 slides toward the air pressure control plug 322 to reset, the gas inside the fixed cylinder 21 can be quickly discharged to the outside air through the conical groove 328, which is conducive to the rapid reset of the air pressure control plug 322.

[0049] A pneumatic cavity 329 is formed between the second fixed block 321 and the air pressure control plug 322. The pneumatic cavity 329 is connected to the second air inlet channel 12 and can receive the airflow from the second air inlet channel 12. When the second air inlet channel 12 is not blocked by the first sealing ring 317, the airflow of the first air inlet channel 11 can pass through the second air inlet channel 12 to reach the pneumatic cavity 329, which can increase the air pressure of the pneumatic cavity 329. The air pressure thrust of the pneumatic cavity 329 and the elastic force of the return spring 324 drive the second sealing ring 323 on the air pressure control plug 322 to seal against the fixed cylinder 21. When the pressure relief sealing ring 80 is separated from the limiter 312, the second air inlet channel 12 is connected to the outside air, so that the pneumatic cavity 329 is also connected to the outside air and is depressurized. The air pressure control plug 322 loses the air pressure support force of the pneumatic cavity 329, so that the air pressure of the transfer cavity 13 can drive the air pressure control plug 322 to slide away from the fixed cylinder 21.

[0050] The working principle of the whole device is:

[0051] In the initial state, the external air source continuously inflates the first air inlet channel 11 through the air inlet valve 14, the control rod 318 is not subjected to external force, and the elastic member 313 drives the first sealing ring 317 to open the second air inlet channel 12 by releasing the elastic force. In addition to the airflow of the first air inlet channel 11 directly flowing into the transfer chamber 13, a part of the airflow flows into the pneumatic cavity 329 through the second air inlet channel 12. The air pressure control plug 322 is sealed against the fixed cylinder 21 through the second sealing ring 323 under the action of the air pressure of the pneumatic cavity 329 and the elastic force of the return spring 324. At this time, the interior of the fixed cylinder 21 is not connected to the transfer chamber 13.

[0052] When it is necessary to hammer an object, the control driving cylinder 319 drives the telescopic rod 320 to press the control rod 318, so that the control rod 318 drives the first sealing ring 317 to block the second air inlet channel 12. At this time, the pneumatic chamber 329 is connected to the external air through the second air inlet channel 112, and the pressure is released. The air pressure of the transfer chamber 13 drives the air pressure control plug 322 to slide out of the fixed cylinder 21, and the gas in the transfer chamber 13 flows into the fixed cylinder 21 instantly and quickly, driving the hammering slide 22 to quickly slide and hammer the object. When the slider 221 abuts the positioning member 16, the air flow inside the fixed cylinder 21 enters the storage chamber 15 through the air inlet 211, and the gas accumulated in the storage chamber 15 flows out to the reset preparation chamber 162 through the air outlet 212. The air pressure of the reset preparation chamber 162 gives the hammering slide 22 an initial reset force, and the weight of the hammering slide 22 drives the hammering slide 22 to slide and reset. During the resetting process of the hammering slide 22, the gas inside the fixed cylinder 21 is driven to be discharged to the external atmosphere through the exhaust channel 325, the first exhaust port 326 and the second exhaust port 327 in sequence, so that the hammering slide 22 can be smoothly reset to prepare for the next hammering of the object.

[0053] The actual action is that the driving cylinder 319 presses the control rod 318 once through the telescopic rod 320 and then quickly retracts, so that the hammering slide 22 can complete a hammering action on the object. When the driving cylinder 319 drives the telescopic rod 320 to reciprocate and retract, the hammering slide 22 can be controlled to cyclically hammer the object.

[0054] A base plate 4 is also connected to the bottom of the shell 1, and a plurality of connecting screw holes 41 are opened on the base plate 4. The device can be installed on other mobile devices using screws through the connecting screw holes 41, and the device can be driven by the mobile device to move to the working position to hammer the target object.

[0055] The housing 1 is also provided with a return sensor 5, which is used to sense whether the hammer head 223 of the hammering slide 22 has returned. When the hammer head 223 returns, the driving cylinder 319 can be controlled to control the hammer head 223 to perform the next hammering. The type of the return sensor 5 is not limited, for example, it can be an ultrasonic sensor or an infrared sensor.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
