Description

Technical Field

[0001] This invention relates to the field of booster cylinder technology, and more specifically to a pneumatic booster cylinder with adjustable speed and rapid positioning. Background Technology

[0002] A pneumatic booster cylinder, or simply booster cylinder, is an energy conversion device that transforms pneumatic power into higher hydraulic pressure. It combines the advantages of a pneumatic cylinder's power component and a hydraulic cylinder's booster component. Using compressed air as a drive source, it converts lower air pressure into higher hydraulic oil pressure through an internal booster structure, ultimately driving an actuator that is smoother and has greater output than a pure pneumatic cylinder. Pneumatic booster cylinders are often used for press-fitting parts. During press-fitting, compressed air initially moves the movable rod. When the rod contacts the part, the compressed air pressure is insufficient to push the rod... When pressing parts with a moving rod, the pressure-boosting structure increases the pressure to press the moving rod into place. However, in the initial movement stage of existing pneumatic booster cylinders, the moving rod impacts the parts at a fixed maximum speed, generating a rigid impact. For fragile parts, this impact can cause damage. In addition, after the press-fitting is completed, the booster piston often continues to advance and compress the hydraulic oil due to mechanical inertia, resulting in overpressure in the oil chamber. Long-term overpressure can damage the chamber of the booster cylinder. To address these issues, we propose a pneumatic booster cylinder with adjustable speed and rapid positioning. Summary of the Invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pneumatic booster cylinder with adjustable speed and rapid positioning to solve the problems existing in the background art.

[0005] The pneumatic component injects air into the pre-compression zone, causing the threaded rod to rotate. By adjusting the air rate, the rotational speed of the threaded rod is adjusted, and with the cooperation of the threaded sleeve, the speed of the press-fitting movable rod is regulated.

[0010] Furthermore, the first air inlet, the second air inlet, and the first air outlet are all connected to the pre-compression zone. The top end of the first air outlet is fixedly connected to an exhaust pipe valve. The top end of the second air outlet is fixedly connected to a connecting air pipe, and the other end of the connecting air pipe is fixedly connected to the third air inlet. One end of the connecting air pipe is equipped with a pressure relief valve. The third air inlet is connected to the boosting zone. An annular air pipe is fixedly sleeved inside the cylinder block assembly, and the annular air pipe connects the second air inlet and the second air outlet.

[0011] Furthermore, the speed regulating component includes a threaded rod, both ends of which are fixedly connected to turbine blades. Rotary rings are rotatably sleeved on the sides of the two turbine blades. The two rotating rings are respectively fixedly sleeved on the inner sides of the outlet ends of air inlet one and air inlet two. A threaded sleeve is rotatably sleeved on the side of one end of the threaded rod. A connecting block is fixedly connected to the top of the threaded sleeve. A press-fit movable rod is fixedly connected to the top of the connecting block.

[0012] Furthermore, the positioning component includes two connecting rods, one end of which is fixedly connected to a clamping plate.

[0013] Furthermore, an oil push chamber is provided on the inner side of the middle part of the cylinder assembly. One end of the oil push chamber is connected to the pre-compression zone, and the other end of the oil push chamber is connected to the hydraulic zone. One end of the press-fit movable rod is located in the oil push chamber. A right-angle oil pipe is fixedly connected to the bottom of the oil push chamber. An annular liquid pipe is fixedly connected to one end of the right-angle oil pipe. Straight pipes are fixedly connected to the inner sides of both ends of the annular liquid pipe. A connecting rod is slidably sleeved on the inner side of one end of each of the two straight pipes.

[0014] Furthermore, the cylinder assembly has a cylinder wall on one inner side, a return spring is fixedly connected to one side of the cylinder wall, the piston assembly includes a piston block, a pressing screw is fixedly connected to the middle of one side of the piston block, and the pressing screw passes through the cylinder wall, and one end of the return spring is fixedly connected to one side of the piston block.

[0015] Furthermore, the pneumatic assembly includes an air pump, one end of which is fixedly connected to a regulating air valve, one end of which is fixedly connected to an air inlet pipe one, and the other end of which is fixedly connected to an air inlet pipe two. The top end of the air inlet pipe one is connected to an air inlet one, and the top end of the air inlet pipe two is connected to an air inlet two.

[0016] The technical effects and advantages of this invention are as follows:

[0017] Air is injected into the second intake pipe using an air pump. The air blows the turbine blades to rotate, which in turn drives the threaded rod to rotate. Since both ends of the threaded rod are fixed to the inside of the turbine blades, the rotation of the threaded rod drives the threaded sleeve to move, which in turn drives the pressing movable rod to move. By adjusting the air rate injected into the second intake pipe, the rotation speed of the turbine blades is adjusted, which in turn adjusts the movement speed of the pressing movable rod. This allows for adjustment of the moving speed of the pressing movable rod according to different pressing parts, avoiding the problem of the movable rod impacting the parts at a fixed maximum speed during the initial movement stage of the pneumatic booster cylinder, which could cause damage to the parts.

[0018] The hydraulic oil is compressed by the extrusion screw, forcing the hydraulic oil in the oil chamber into the annular liquid pipe. The hydraulic oil in the annular liquid pipe then pushes the connecting rod to move. The connecting rod pushes the clamping plate, causing the clamping plate to clamp the extrusion screw. The friction between the clamping plate and the extrusion screw reduces the inertia of the extrusion screw, stopping its forward movement. This solves the problem in pneumatic booster cylinders where, after the booster piston continues to advance and compress the hydraulic oil after press-fitting, it causes overpressure in the oil chamber, resulting in damage to some chambers of the booster cylinder.

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The adjustable speed and rapid positioning pneumatic booster cylinder involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Reference Figure 1 and Figure 2 This invention provides a pneumatic booster cylinder with adjustable speed and rapid positioning, comprising a cylinder assembly 101, a mounting bracket 108 fixedly sleeved on the side of the cylinder assembly 101, a press-fit movable rod 102 slidably sleeved on the inner side of the cylinder assembly 101, a speed regulating component 103 fixedly sleeved on the bottom inner side of one end of the cylinder assembly 101, a positioning component 104 slidably sleeved on the inner side of the middle part of the cylinder assembly 101, a return spring 105 fixedly sleeved on the inner side of the other end of the cylinder assembly 101, a piston assembly 106 fixedly connected to one end of the return spring 105, and the piston assembly 106 located on the inner side of one end of the cylinder assembly 101, and a pneumatic component 107 fixedly connected to the bottom of the cylinder assembly 101, and the pneumatic component 107 fixedly connected to the bottom of the mounting bracket 108.

[0030] In this embodiment, it is necessary to further explain that the speed regulating component 103 and the pneumatic component 107 avoid the problem that the moving rod of the pneumatic booster cylinder will hit the parts at a fixed maximum speed during the initial movement stage, causing damage to the parts. The positioning component 104 and the return spring 105 solve the problem that after the booster structure of the pneumatic booster cylinder is pressed, the booster piston continues to advance and compresses the hydraulic oil, causing overpressure in the oil chamber and damaging the booster cylinder chamber. The specific structure and working principle of the above components will be explained in detail later.

[0031] Reference Figure 2 and Figure 3 The cylinder assembly 101 has a pre-compression zone 1011 on the inner side of one end, a hydraulic zone 1012 on the inner side of the middle part of the cylinder assembly 101, a booster zone 1013 on the inner side of the other end of the cylinder assembly 101, an air inlet 1 at one end of the bottom of the cylinder assembly 101, an air inlet 2 in the middle of the bottom of the cylinder assembly 101, an air outlet 1 at one end of the top of the cylinder assembly 101, and an air outlet 2 in the middle of the top of the cylinder assembly 101. The other end of the top is provided with an air inlet three. Air inlet one, air inlet two, and air outlet one are all connected to the pre-compression zone 1011. An exhaust pipe valve is fixedly connected to the top of air outlet one. A connecting air pipe is fixedly connected to the top of air outlet two, and the other end of the connecting air pipe is fixedly connected to air inlet three. An overflow valve is provided at one end of the connecting air pipe. Air inlet three is connected to the boosting zone 1013. An annular air pipe is fixedly sleeved inside the cylinder block assembly 101, and the annular air pipe connects air inlet two and air outlet two.

[0032] Reference Figure 3 and Figure 4 The speed regulating component 103 includes a threaded rod 1031, with turbine blades 1032 fixedly connected to both ends of the threaded rod 1031. Rotary rings are rotatably sleeved on the sides of the two turbine blades 1032, and the two rotating rings are respectively fixedly sleeved on the inner sides of the outlet ends of the first and second air inlets. A threaded sleeve 1033 is rotatably sleeved on the side of one end of the threaded rod 1031, and a connecting block is fixedly connected to the top of the threaded sleeve 1033. A press-fit movable rod 102 is fixedly connected to the top of the connecting block.

[0033] Reference Figure 3 , Figure 5 and Figure 6The positioning component 104 includes two connecting rods 1041, one end of each connecting rod 1041 is fixedly connected to a clamping plate 1042. The inner side of the middle part of the cylinder assembly 101 is provided with an oil push chamber. One end of the oil push chamber is connected to the pre-compression area 1011, and the other end of the oil push chamber is connected to the hydraulic area 1012. One end of the press-fit movable rod 102 is located in the oil push chamber. The bottom of the oil push chamber is fixedly connected to a right-angle oil pipe. One end of the right-angle oil pipe is fixedly connected to an annular liquid pipe 1043. The inner sides of both ends of the annular liquid pipe 1043 are fixedly connected to straight pipes. The inner sides of one end of each of the two straight pipes are slidably sleeved with connecting rods 1041.

[0034] In this embodiment, it should be specifically noted that the right-angle oil pipe, the annular liquid pipe 1043, and the straight pipe are all located inside the cylinder block assembly 101.

[0035] Reference Figure 2 and Figure 7 The cylinder assembly 101 has a cylinder wall on one inner side, and a return spring 105 is fixedly connected to one side of the cylinder wall. The piston assembly 106 includes a piston block 1061, and a pressing screw 1062 is fixedly connected to the middle of one side of the piston block 1061, and the pressing screw 1062 passes through the cylinder wall. One end of the return spring 105 is fixedly connected to one side of the piston block 1061.

[0036] When the press-fitting movable rod 102 contacts the part and is blocked from moving forward by the part, the air injected into the pre-pressurization zone 1011 by the pneumatic assembly 107 is insufficient to achieve press-fitting. At this time, air is continuously injected into the second air inlet, and the press-fitting movable rod 102 cannot move forward, causing the turbine fan blade 1032 to be unable to rotate, which increases the pressure in the annular air pipe. At this time, the pressure relief valve opens, and air enters the pressurization zone 1013 from the connecting air pipe, pushing the piston assembly 106 forward. The piston assembly 106 pushes the hydraulic oil, which in turn pushes the press-fitting movable rod 102 to complete the pressurization.

[0037] The hydraulic oil is compressed by the extrusion screw 1062, which forces the hydraulic oil in the hydraulic zone 1012 into the annular liquid pipe 1043. The hydraulic oil in the annular liquid pipe 1043 then pushes the connecting rod 1041 to move. The connecting rod 1041 pushes the clamping plate 1042, which clamps the extrusion screw 1062. The friction of the clamping plate 1042 on the extrusion screw 1062 reduces the inertia of the extrusion screw 1062, causing it to stop moving forward. This solves the problem that after the pressurization structure of the pneumatic booster cylinder is completed, the booster piston continues to advance and compress the hydraulic oil, causing overpressure in the oil chamber and damaging the booster cylinder chamber.

[0038] In this embodiment, it is necessary to further explain that the piston assembly 106 pushes the hydraulic oil, which in turn pushes the press-fitting movable rod 102 to increase the pressure. The principle of this is existing technology, so it will not be described in detail.

[0039] A stationary block is fixedly connected to the middle of the inner side of the clamping plate 1042. A movable block is slidably connected to the top and bottom of the inner side of the clamping plate 1042. A rotating shaft is provided on the back of the movable block and connected to the clamping plate 1042. The movable block is deflected by the force of the extrusion screw 1062.

[0040] The combination of the stationary block and the moving block forms an adaptive clamping surface. When there is a slight dimensional deviation or surface roughness difference in the extrusion screw 1062, the moving block can compensate for the deviation by deflection, ensuring the fit between the clamping plate 1042 and the screw, and avoiding positioning offset caused by insufficient contact. The deflection angle of the moving block can be adaptively adjusted according to the diameter of the extrusion screw 1062, without the need to replace the special clamping plate, which improves the versatility of the device and reduces the replacement cost when pressing multi-specification parts.

[0041] In this embodiment, it is necessary to further explain that the stationary block, as the core support point, fits against the middle section of the extrusion screw 1062, providing basic positioning support. The moving blocks at the top and bottom can be deflected through the rotating shaft. When contacting the extrusion screw, they will adaptively adjust the angle according to the curvature of the screw surface, forming a three-point fit. This avoids the clamping plate 1042 directly contacting the extrusion screw 1062 rigidly, and solves the problem that the concentrated clamping force can easily lead to wear and scratches on the screw surface, especially in high-frequency positioning scenarios, where the screw accuracy will gradually decrease. The sliding connection of the moving block and the deflection of the rotating shaft are conventional mechanical means, such as a slide rail structure, and therefore will not be described in detail.

[0042] Reference Figure 4 and Figure 8 The pneumatic assembly 107 includes an air pump 1071. One end of the air pump 1071 is fixedly connected to an adjusting air valve 1072. One end of the adjusting air valve 1072 is fixedly connected to an air inlet pipe 1073. The other end of the adjusting air valve 1072 is fixedly connected to an air inlet pipe 1074. The top end of the air inlet pipe 1073 is connected to an air inlet port 1, and the top end of the air inlet pipe 1074 is connected to an air inlet port 2.

[0043] Air is injected into the second air intake pipe 1074 using an air pump 1071. The air blows the turbine blade 1032 to rotate, which in turn drives the threaded rod 1031 to rotate. Since the two ends of the threaded rod 1031 are fixed to the inside of the turbine blade 1032, the rotation of the threaded rod 1031 drives the threaded sleeve 1033 to move, which in turn drives the pressing movable rod 102 to move. By adjusting the air rate injected into the second air intake pipe 1074 by the air pump 1071, the rotation speed of the turbine blade 1032 is adjusted, which in turn adjusts the movement speed of the pressing movable rod 102. This allows the movement speed of the pressing movable rod to be adjusted according to different pressing parts, thus avoiding the problem of the movable rod hitting the parts at a fixed maximum speed and causing damage to the parts during the initial movement stage of the pneumatic booster cylinder.

[0044] After the pressing is completed, the pneumatic component 107 injects air into the air inlet pipe 1073. The air blows in the opposite direction to rotate the turbine fan blade 1032, causing the speed regulating component 103 to rotate in the opposite direction, which causes the pressing movable rod 102 to retract, thus completing one pressing cycle.

[0045] In this embodiment, it should be specifically explained that the regulating valve 1072 is used to regulate the air flow direction of the air pump 1071.

[0046] The working principle of this invention is as follows: Air is injected into the second air intake pipe 1074 by the air pump 1071. The air blows the turbine blade 1032 to rotate, which in turn drives the threaded rod 1031 to rotate. Since the two ends of the threaded rod 1031 are fixed to the inside of the turbine blade 1032, the rotation of the threaded rod 1031 drives the threaded sleeve 1033 to move, which in turn drives the pressing movable rod 102 to move. By adjusting the air rate injected into the second air intake pipe 1074 by the air pump 1071, the rotation speed of the turbine blade 1032 is adjusted, which in turn adjusts the moving speed of the pressing movable rod 102. In this way, the moving speed of the pressing movable rod can be adjusted according to different pressing parts, thus avoiding the problem that the movable rod hits the parts at a fixed maximum speed and causes damage to the parts during the initial movement stage of the pneumatic booster cylinder.

[0047] The hydraulic oil is compressed by the extrusion screw 1062, which forces the hydraulic oil in the hydraulic zone 1012 into the annular liquid pipe 1043. The hydraulic oil in the annular liquid pipe 1043 then pushes the connecting rod 1041 to move. The connecting rod 1041 pushes the clamping plate 1042, which clamps the extrusion screw 1062. The friction of the clamping plate 1042 on the extrusion screw 1062 reduces the inertia of the extrusion screw 1062, causing it to stop moving forward. This solves the problem that after the pressurization structure of the pneumatic booster cylinder is completed, the booster piston continues to advance and compress the hydraulic oil, causing overpressure in the oil chamber and damaging the booster cylinder chamber.
