Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air cylinders, in particular to an air cylinder locking mechanism. BACKGROUND

[0002] An air cylinder is a kind of pneumatic actuator that converts the pressure energy of compressed air into mechanical energy, mainly used to realize linear reciprocating motion, and widely used in mechanical automation, industrial production and aerospace fields.

[0003] An air cylinder is mainly composed of a cylinder barrel, a piston rod and a sealing element, and is divided according to the action mode. The air cylinder is divided into a single-acting air cylinder and a double-acting air cylinder. The single-acting air cylinder is driven by single-direction air pressure, and the reset relies on a spring or gravity. The structure is simple, and the air consumption is low. The double-acting air cylinder is driven by bidirectional air pressure, and the output force is stable, which is suitable for scenes requiring bidirectional motion.

[0004] The air cylinder locking mechanism is a key component for ensuring the precise positioning of a mechanical system. By locking the position of the piston rod, it effectively resists external force impact, air pressure fluctuation and gravity influence. Taking a double-acting air cylinder as an example, the piston rod extends from one end of the cylinder barrel in its internal structure. The piston divides the cylinder barrel into a rod cavity and a rodless cavity. The rodless cavity is driven by air intake to extend the piston rod, and the rod cavity is driven by air intake to retract. A sealing ring is provided at the connection between the piston rod and the cylinder barrel to prevent air leakage from the rod cavity.

[0005] However, the traditional locking mechanism has significant defects. Firstly, because the piston rod is fixed by clamping force, frequent extension and retraction movements and clamping actions will cause excessive wear on the surface of the rod body, damage the sealing between the piston rod and the sealing ring, cause air leakage in the rod cavity, and accelerate the failure of the air cylinder. Secondly, the existing locking mechanism needs to be controlled independently, which not only increases the system complexity, but also increases energy consumption and maintenance costs, and easily causes time delay in the extension and retraction actions of the air cylinder, resulting in decreased positioning accuracy and affecting the overall operation stability of the equipment. SUMMARY

[0006] The purpose of the present application is to solve the problems of excessive wear on the surface of the rod body caused by frequent clamping actions of the locking mechanism, damage to the sealing between the piston rod and the sealing ring, and the need for independent control of the locking mechanism, which not only increases the system complexity, but also easily causes time delay in the extension and retraction actions of the air cylinder. A kind of air cylinder locking mechanism is proposed.

[0007] In order to achieve the above purpose, the present application adopts the following technical solution: an air cylinder locking mechanism comprising an outer shell, a guide ring rotatably connected inside the outer shell, a plurality of circumferentially equidistant clamping plates slidably connected to the inner wall of the guide ring, and a pressure applying unit provided between the outer shell and the clamping plates, further comprising:

[0008] An unlocking unit comprising a ring-shaped piston slidably connected inside the outer shell, and a push plate fixed to one side of the ring-shaped piston.

[0009] The position switching unit comprises an elastic push rod slidingly mounted on one side of the push plate, one side of the guide ring is fixed with a ring-shaped part, and the inner part of the ring-shaped part is fixed with a convex strip;

[0010] and a gas flow control assembly.

[0011] After the unlocking unit pushes the clamping plate to be unlocked each time, the position switching unit deflects the clamping plate to switch the contact position of the cylinder piston push rod and the clamping plate when locking again.

[0012] As a further description of the above technical solution: the pressure applying unit comprises a pressing plate slidingly connected to the inside of the shell, and a compression spring and a positioning rod are arranged between the pressing plate and the inner wall of the shell.

[0013] As a further description of the above technical solution: the guide ring, the clamping plate, the pressure applying unit, the unlocking unit and the position switching unit are all provided with two groups and are symmetrically arranged inside the shell.

[0014] As a further description of the above technical solution: the gas flow control assembly comprises a gas tank, the inside of the gas tank is fixed with a partition plate for dividing the inside space of the gas tank into an upper chamber and a lower chamber, the top of the gas tank is fixed with a connecting pipe, the inside of the connecting pipe is slidingly connected with a gas conveying pipe, and the inside of the gas tank is provided with an adjusting part.

[0015] As a further description of the above technical solution: a three-way pipe is fixed between the lower chamber of the gas tank and the cylinder barrel, an electromagnetic valve is arranged at the connecting position of the three-way pipe and the cylinder barrel, and the upper chamber of the gas tank is communicated with the inside of the shell through a pipeline.

[0016] As a further description of the above technical solution: the adjusting part comprises a bottom frame fixed to the bottom of the partition plate, an electromagnet is fixed to the bottom of the bottom frame, a tension spring is fixed between the gas conveying pipe and the inner wall of the gas tank, and a pressure sensor for detecting the pressure of the upper chamber of the gas tank is arranged on one side of the gas tank.

[0017] As a further description of the above technical solution: an exhaust unit is arranged on the connecting pipe, the exhaust unit comprises a sealing plug fixed to the inside of the connecting pipe, a sliding block is slidingly connected to the inside of the connecting pipe and abuts against the sealing plug, a spring pin is slidingly mounted in the inside of the sliding block, and a return spring is arranged between the sliding block and the connecting pipe.

[0018] As a further description of the above technical solution: a cover is fixed to the outside of the connecting pipe, and a flow guide ring is fixed to the bottom of the shell and communicated with the cover through a pipeline.

[0019] As described above, due to the adoption of the above technical cylinder locking mechanism, the beneficial effects of the present application are:

[0020] Firstly, the position switching unit can change the relative position of the clamping plate and the piston rod of the air cylinder after each unlocking. On the one hand, this can avoid air leakage at the contact position of the piston rod and the sealing ring due to local long-term wear during stretching and contraction, thereby prolonging the service life of the air cylinder. On the other hand, the radial load borne by the piston rod of the air cylinder will be borne by the clamping plate, and the design of the switchable position of the clamping plate can disperse the load action point, prevent a single clamping plate from being damaged due to frequent loading, and further improve the use effect and service life of the device.

[0021] Secondly, the air flow control assembly cooperates with the unlocking unit to automatically complete the unlocking and locking of the piston push rod before and after each stretching and contraction of the air cylinder. This design not only simplifies the structural complexity of the air cylinder system, but also enhances the action coordination between the air cylinder and the locking mechanism, effectively shortens the time delay between the stretching and contraction movement of the air cylinder and the locking action, and significantly improves the positioning accuracy of the air cylinder.

[0022] Thirdly, during the process of automatically locking the piston push rod after the stretching and contraction of the air cylinder, the application uses the cover body and the flow guide ring to guide the gas leaked from the gas tank to the surface of the piston push rod, blows away the impurities between the piston push rod and the clamping plate through the air flow, prevents the impurities from interfering with the locking, ensures the uniform and reliable locking force, reduces the abnormal wear caused by the impurities, protects the surface of the piston push rod and the clamping plate, and prolongs the service life of the key components.

[0038] Reference Figure 7 andFigure 9 Further comprising an unlocking unit 14, the unlocking unit 14 comprises a ring-shaped piston 141 which is slidingly connected inside the shell 10, one side of the ring-shaped piston 141 is fixed with a push plate 142, the ring-shaped piston 141 can slide inside the shell 10 by air pressure, driving the push plate 142 to push the clamping plate 12, so that the clamping plate 12 no longer clamps the piston push rod, realizing the unlocking of the air cylinder.

[0039] With reference to Figure 4 In order to enhance the action coordination between the air cylinder and the locking mechanism, further comprising an airflow control assembly 20, the airflow control assembly 20 comprises a gas tank 21 fixed to the end of the air cylinder, the inside of the gas tank 21 is fixed with a partition plate 22 which divides the internal space of the gas tank 21 into an upper chamber and a lower chamber.

[0040] With reference to Figure 1 and Figure 2 The lower chamber of the gas tank 21 and the cylinder barrel are fixed with a three-way pipe 29, two interfaces of the three-way pipe 29 are respectively installed with electromagnetic valves 210 at the connection with the cylinder barrel, by controlling the opening and closing of the two electromagnetic valves 210, air can be respectively introduced into the rod cavity and the rodless cavity of the air cylinder, so as to realize the contraction or elongation of the air cylinder.

[0041] With reference to Figure 3 and Figure 4 The upper chamber of the gas tank 21 is communicated with the inside of the shell 10 through a pipeline, the top of the gas tank 21 is fixed with a connecting pipe 23 and is communicated with the external compressor through the connecting pipe 23, the inside of the connecting pipe 23 is slidingly connected with a gas conveying pipe 24, the bottom end of the gas conveying pipe 24 penetrates through the partition plate 22 and is sealed with the partition plate 22, the inside of the gas tank 21 is provided with an adjusting component 25 for switching the position of the gas conveying pipe 24;

[0042] When the air cylinder is controlled to stretch and contract by compressed air, the compressed air first enters the upper chamber of the gas tank 21 through the connecting pipe 23 and the gas conveying pipe 24, and then enters the shell 10 through the pipeline, so as to realize the automatic unlocking before the stretching and contraction of the air cylinder in cooperation with the unlocking unit 14.

[0043] With reference to Figure 8 and Figure 9, in order to avoid the piston push rod locking and unlocking frequently caused by local excessive wear, the position switching unit 15 is further included, the position switching unit 15 includes the elastic push rod 151 slidingly installed on one side of the push plate 142, the ring-shaped part 152 is fixed on one side of the guide ring 11, the inner wall of the ring-shaped part 152 is provided with a guide groove, the convex strip 153 is fixed in the guide groove of the ring-shaped part 152, and the side, away from the elastic push rod 151, of the convex strip 153 is a slope; after the push plate 142 pushes the clamp plate 12 to unlock the piston push rod each time, the push plate 142 continues to move towards the clamp plate 12, at this time, the push plate 142 drives the elastic push rod 151 to enter the guide groove of the ring-shaped part 152, the ring-shaped part 152 drives the ring-shaped part 152, the guide ring 11 and the clamp plate 12 to deflect through the guide effect of the guide groove and the inclined convex strip 153, the relative position of the clamp plate 12 and the piston push rod is switched, the contact position of the clamp plate 12 and the piston push rod is changed when the clamp plate 12 locks the piston push rod again, and local wear of the piston push rod is avoided;

[0044] Considering that the piston push rod will inevitably be subjected to radial load when the cylinder is in operation and the radial load will be transmitted to the clamp plate 12, the design of continuously switching the position of the clamp plate 12 can also make each clamp plate 12 be uniformly utilized, prevent a single clamp plate 12 from being damaged due to frequent bearing, and further improve the use effect and service life of the device;

[0045] When the push plate 142 drives the elastic push rod 151 to reset, the elastic push rod 151 is in contact with the convex strip 153 and shrinks under the extrusion of the inclined surface of the other convex strip 153, after the elastic push rod 151 shrinks, the elastic push rod 151 is reset after being staggered with the convex strip 153 and is popped out under the elastic force of the elastic push rod 151, so as to push the ring-shaped part 152 to deflect again with the unlocking unit 14.

[0046] With reference to Figure 4 The adjusting component 25 includes the bottom frame 251 fixed to the bottom of the partition plate 22, the electromagnet 252 is fixed to the bottom of the bottom frame 251, the tension spring 253 is fixed between the gas conveying pipe 24 and the inner wall of the gas tank 21, the pressure sensor 254 for detecting the pressure of the upper chamber of the gas tank 21 is installed on one side of the gas tank 21, the electromagnet 252 is energized after the pressure sensor 254 detects that the pressure of the upper chamber increases, at this time, the electromagnet 252 drives the gas conveying pipe 24 to move downwards through the magnetic force, so that the gas conveying pipe 24 communicates the connecting pipe 23 with the lower chamber of the gas tank 21, at this time, the tension spring 253 is stretched, and the external compressor communicates the compressed control into the cylinder barrel of the cylinder through the connecting pipe 23, the gas conveying pipe 24, the lower chamber and the three-way pipe 29, so as to control the operation of the cylinder.

[0047] With reference to Figure 4 and Figure 5, in order to lock the piston push rod automatically after the cylinder operation, the connecting pipe 23 is provided with an exhaust unit 26, the exhaust unit 26 includes a sealing plug 261 fixed in the connecting pipe 23, the connecting pipe 23 is slidably connected with a sliding block 262 abutting and sealing with the sealing plug 261, the sliding block 262 is slidably installed with a spring pin 263, and the sliding block 262 and the connecting pipe 23 are provided with a reset spring 264.

[0048] When the gas delivery pipe 24 moves downward, the top end of the gas delivery pipe 24 applies a downward thrust to the spring pin 263, at this time the sliding block 262 cannot move downward, the spring pin 263 is retracted into the inside of the sliding block 262 under the thrust, so that the gas delivery pipe 24 and the spring pin 263 are staggered, and the air hole on the sealing plug 261 is in a closed state;

[0049] Referring to Figure 6 After the cylinder contracts, the control electromagnet 252 is de-energized, the tension spring 253 is retracted to drive the gas delivery pipe 24 to move upward, at this time the top end of the gas delivery pipe 24 applies an upward thrust to the spring pin 263, the spring pin 263 drives the sliding block 262 to move upward, so that the air hole of the sealing plug 261 is opened, the compressed air in the upper chamber of the gas tank 21 and the inside of the shell 10 is discharged through the air hole of the sealing plug 261, after the pressure in the inside of the shell 10 decreases, the push plate 142 no longer applies a thrust to the clamping plate 12, at this time the elastic force of the compression spring 131 drives the pressing plate 132 to push the clamping plate 12, so that the clamping plate 12 locks the piston push rod again.

[0050] The gas delivery pipe 24 continues to move upward to drive the spring pin 263 and the sliding block 262 to move upward, the compression degree of the reset spring 264 gradually increases, so that the force between the spring pin 263 and the gas delivery pipe 24 gradually increases, after the gas delivery pipe 24 rises to the highest position, the spring pin 263 is extruded and retracted into the sliding block 262, at this time the spring pin 263 loses the thrust of the gas delivery pipe 24 and resets under the elastic force of the reset spring 264.

[0051] Referring to Figure 7 The guide ring 11, the clamping plate 12, the pressure applying unit 13, the unlocking unit 14 and the position switching unit 15 are provided with two groups and symmetrically arranged in the inside of the shell 10, when the clamping plate 12 locks and unlocks the piston push rod, the friction forces applied to the piston push rod by the two groups of clamping plates 12 are offset, so that the piston push rod is prevented from moving to affect the cylinder extension and contraction accuracy due to locking or unlocking.

[0052] Referring to Figure 5 and Figure 7The outer part of the connecting pipe 23 is fixed with a cover 27, and the bottom of the shell 10 is fixed with a flow guide ring 28 which is communicated with the cover 27 through a pipe. The flow is guided through the cover 27 and the flow guide ring 28, so that the compressed air in the upper chamber of the gas tank 21 and the inside of the shell 10 is discharged to the space between the clamping plate 12 and the piston push rod, and the impurities between the piston push rod and the clamping plate 12 are blown away by the air flow, so as to prevent the impurities from interfering with the locking and ensure the uniform and reliable locking force.

[0053] Working principle: in the initial state, the gas delivery pipe 24 is communicated with the upper chamber of the gas tank 21, the cylinder piston push rod is out of the shell 10, the elastic force of the compression spring 131 is applied to the clamping plate 12 through the pressing plate 132, so that the clamping plate 12 is pressed between the guide ring 11 and the piston push rod under the guidance of the inner wall of the guide ring 11, and the piston push rod is locked;

[0054] When the cylinder is used, the compressed air is introduced into the upper chamber of the gas tank 21 through the connecting pipe 23 and the gas delivery pipe 24 by using the external compressor. At this time, the compressed air enters the inside of the shell 10 through the pipe, the pressure in the inside of the shell 10 increases, the annular piston 141 drives the push plate 142 to push the clamping plate 12, the compression spring 131 is further compressed, and the clamping plate 12 is no longer locked with the piston push rod;

[0055] The push plate 142 continues to move to drive the elastic push rod 151 into the guide groove of the annular part 152. The annular part 152 is guided by the guide groove and the inclined convex strip 153 to drive the annular part 152, the guide ring 11 and the clamping plate 12 to deflect, so as to switch the relative position of the clamping plate 12 and the piston push rod;

[0056] After the pressure in the inside of the shell 10 and the upper chamber increases, the pressure sensor 254 controls the electromagnet 252 to generate magnetic force by detecting the pressure. The electromagnet 252 drives the gas delivery pipe 24 to move downward by magnetic force, so that the gas delivery pipe 24 communicates the connecting pipe 23 with the lower chamber. At this time, the upper chamber is in a sealed state, and the compressor continues to introduce compressed air. After the air enters the lower chamber through the connecting pipe 23 and the gas delivery pipe 24, it enters the cylinder barrel through the three-way pipe 29, so as to push the piston push rod to extend or retract;

[0057] After the cylinder ends the action, the compressor is stopped and the electromagnet 252 is powered off, at this time the tension spring 253 is pulled up to reset by the elastic force, in the process of the gas pipe 24 moving upward, the top end applies an upward thrust to the spring pin 263, the spring pin 263 drives the slider 262 to move upward, the sealing plug 261 loses the sealing of the slider 262 and opens, the compressed air in the upper chamber of the gas tank 21 and the inside of the shell 10 is discharged through the air hole of the sealing plug 261, after the pressure in the inside of the shell 10 decreases, the push plate 142 no longer applies a thrust to the clamping plate 12, at this time the elastic force of the compression spring 131 drives the pressing plate 132 to push the clamping plate 12, the clamping plate 12 locks the piston push rod again, the push plate 142 drives the elastic push rod 151 to be separated from the guide groove;

[0058] The discharged air is guided to be sprayed to the clamping plate 12 and the piston push rod through the cover body 27 and the guide ring 28, the impurities between the piston push rod and the clamping plate 12 are blown away through the air flow, and the impurities are prevented from interfering with the locking.

[0059] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical air cylinder locking mechanism and the invention concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
