Description

Technical Field

[0001] This utility model relates to the field of loading and unloading connection pipe technology, and in particular to a clutch mechanism for two-axis transmission and an automatic clamping system with a clutch mechanism. Background Technology

[0002] Hoses have a wide range of applications in industry, primarily used to connect a rigid connection point or in situations where a rigid connection between two points is difficult to achieve. They are also commonly used in applications requiring flexibility to transport various media. To ensure their safety and reliability under high-pressure environments, hoses need to undergo pressure tests to evaluate their ability to withstand different pressures and ensure that they will not rupture or leak under operating pressure. During the test, the hose is filled with water and pressurized to the test pressure, which is maintained for a certain period of time to check for deformation, leakage, or other forms of malfunction.

[0003] Chinese patent (CN 218470406 U) provides a pressure test fixture for adapting to multi-specification flange connection hoses. It is provided with a U-shaped fixing bracket for initially fixing the hose flange, and a pair of horizontally mirror-symmetrical first U-shaped plate frames and second U-shaped plate frames. The first U-shaped plate frames and second U-shaped plate frames are driven to move towards each other by a second linear drive mechanism to tighten and center the hose flange, thereby achieving longitudinal limiting of the hose flange and improving the tightening and centering effect.

[0004] However, this method has the following problems: 1) It cannot guarantee that the hose and the pressurizing component are precisely aligned after clamping; 2) The process of placing the hose on the clamp and clamping it is too cumbersome and inefficient. Utility Model Content

[0032] The present invention will now be described in detail with reference to the accompanying drawings.

[0033] Example 1

[0034] like Figures 1 to 2 As shown, a clutch mechanism 100 for two-shaft transmission according to this utility model includes a clutch mechanism bearing housing 110, a first bearing 120, a cylinder module 130, and a second bearing 140. The outer ring of the first bearing 120 is fixedly connected to the clutch mechanism bearing housing 110, and its inner ring can be fixedly connected to an external power input shaft. The cylinder module 130 is disposed inside the clutch mechanism bearing housing 110. The outer ring of the second bearing 140 is connected to the cylinder module 130, and its inner ring is provided with several keyways. The second bearing 140 can be keyed to an external power input shaft and a power output shaft.

[0035] The first bearing 120 is a standard rolling bearing component, which specifically includes an outer ring (not shown), rolling elements (not shown) and an inner ring (not shown). Its outer ring is fixedly connected to the clutch mechanism bearing housing 110, and its inner ring is fixedly connected to the power input shaft. The first bearing 120 is used to support the power input shaft and reduce the frictional torque during its movement.

[0036] The cylinder module 130 includes a piston chamber 131, a piston 132, a piston rod 133 fixedly connected to the piston 132, and an end cap 134. The piston chamber 131 is disposed within the clutch mechanism bearing seat 110. The piston 132 is disposed within the piston chamber 131 and can slide within the piston chamber 131. The piston rod 133 is fixedly connected to the piston 132 and extends to the outside of the clutch mechanism bearing seat 110. Under the action of the piston 132, the piston rod 133 moves linearly along the axial direction of the power input shaft. The end cap 134 is disposed at one end of the piston chamber 131, and the piston rod 133 passes through the end cap 134. The end cap 134 is used to close the piston chamber 131 and fix the piston rod 133.

[0037] To prevent gas from leaking from the gap between the piston rod 133 and the end cap 134, a sealing element (not shown), such as a rubber ring, is also provided on the end cap 134.

[0038] In this embodiment, the second bearing 140 is disposed outside the clutch mechanism bearing housing 110 and is a non-standard rolling bearing component. Specifically, it includes an outer ring (not shown), rolling elements (not shown), and a second bearing inner ring 141. The outer ring is fixedly connected to the piston rod 133. The two ends of the second bearing inner ring 141 are respectively provided with a first elongated keyway 141A and a second elongated keyway 141B. The power input shaft is connected to the inner ring key of the second bearing 140 through the first elongated keyway 141A, and the power output shaft is connected to the inner ring key of the second bearing 140 through the second elongated keyway 141B.

[0039] The length of the connection between the power input shaft and the second bearing 140 should be such that after the second bearing 140 moves under the action of the cylinder module 130, the power input shaft is still connected to the second bearing 140. Since the length depends on the relative position of the clutch mechanism 100 and the power output shaft, no special limit is placed on its specific length in this application.

[0040] To improve the alignment accuracy of the power input shaft and the power output shaft, a number of first elongated keyways 141A and second elongated keyways 141B are provided; their specific number is determined according to the torque that the power input shaft and the power output shaft need to transmit, and no specific limitation is made in this application.

[0041] When cylinder module 130 is not working, the second bearing 140 is not connected to the power output shaft, and the system is in a disengaged state. In this state, there is no direct mechanical connection between the power input shaft and the power output shaft, so the rotational power of the power input shaft is not transmitted to the power output shaft, and the power output shaft remains stationary.

[0042] When the cylinder module 130 operates, the piston 132 inside the piston chamber 131 moves linearly in a certain direction under the action of air pressure. The movement of the piston 132 pushes the second bearing 140 to move in the same direction, thereby enabling the second bearing 140 to be keyed to the power output shaft. At this time, the system is in a coupled state. In this state, a mechanical connection is established between the power input shaft and the power output shaft through the second bearing 140, and the rotation of the power input shaft can be transmitted to the power output shaft through the second bearing 140, realizing the transmission of power.

[0043] When it is necessary to switch from the coupling state to the disconnected state, the cylinder module 130 can be reversed, the piston 132 retracts, thereby driving the second bearing 140 to move in the opposite direction, so as to disengage it from the power output shaft and achieve disconnection.

[0044] Compared with the prior art, this utility model realizes the switching between coupling and decoupling between two shafts through the drive of the cylinder module, which has the advantages of compact structure and convenient operation, and can be used in mechanical transmission systems that require frequent switching of power transmission states.

[0045] In addition, such as Figures 3 to 4 As shown, this utility model also provides an automatic clamping system 200 with a clutch mechanism, including the clutch mechanism 100 for two-axis transmission described in Embodiment 1, comprising:

[0046] A fixed base 210;

[0047] A gantry 220 is arranged vertically opposite to the fixed base 210, with the gantry 220 located above the fixed base 210 and rotatably connected to the fixed base 210.

[0048] And a lower clamping plate 230 disposed within the fixed base 210 and slidably connected to the fixed base 210;

[0049] and an upper clamping plate 240 disposed within the gantry 220 and slidably connected to the gantry 220, the upper clamping plate 240 and the upper clamping plate 240 being disposed opposite to each other;

[0050] A drive module 250 is disposed within the gantry 220 and the fixed base 210. The drive module 250 causes the upper clamping plate 240 to move toward each other, thereby achieving centering and clamping of the hose.

[0051] In order to better fit the surface of the workpiece and achieve precise positioning, the upper edge of the lower clamping plate 230 and the lower edge of the upper clamping plate 240 are U-shaped or V-shaped; in this embodiment, the upper edge of the lower clamping plate 230 and the lower edge of the upper clamping plate 240 are U-shaped.

[0052] like Figure 5 As shown, the drive module 250 includes a motor 251 fixedly installed in the gantry 220, a first transmission mechanism 252 connected to the motor 251 and installed in the gantry 220 and the fixed base 210, a clutch mechanism 100 installed in the fixed base 210 for switching the power transmission between the first transmission mechanism 252 and the reverse transmission mechanism 253, the reverse transmission mechanism 253 installed in the fixed base 210, and a second transmission mechanism 254 installed in the fixed base 210.

[0053] The motor 251 is mainly used to output power to provide movement for the first transmission mechanism 252. Its specific type is not the focus of this invention, and therefore this application does not limit it.

[0054] like Figure 6 As shown, the first transmission mechanism 252 is a ball screw transmission mechanism, including a first screw 2521 fixedly connected to the output shaft of the motor 251, and a first moving block 2522 sleeved on the first screw 2521 by a plurality of balls (not shown) and forming a helical pair with the first screw 2521. The first screw 2521 passes through the gantry 220 and extends into the fixed base 210. The first moving block 2522 is fixedly connected to the upper clamping plate 240.

[0055] Under the action of the motor 251, the first lead screw 2521 rotates, and the first moving block 2522 moves linearly along the axial direction of the first lead screw 2521 on the gantry 220 under the action of the first lead screw 2521, thereby driving the upper clamping plate 240 to also move linearly along the axial direction of the first lead screw 2521.

[0056] In order to enable the upper clamping plate 240 to move relative to each other in the vertical direction, the first lead screw 2521 is arranged in the vertical direction.

[0057] In some embodiments, the first moving block 2522 and the upper clamping plate 240 may be assembled from multiple components or be a one-piece structure; in this embodiment, the first moving block 2522 and the upper clamping plate 240 are a one-piece structure, and the upper clamping plate 240 has a through hole on one side and is sleeved on the first lead screw 2521.

[0058] In order to support the first lead screw 2521, the first transmission mechanism 252 further includes a first lead screw bearing assembly 2523, which includes a first lead screw bearing unit 2523A and a second lead screw bearing unit (not shown). The first lead screw bearing unit 2523A is fixedly disposed in the gantry 220 and is used to support the end of the first lead screw 2521 that is connected to the motor 251. The second lead screw bearing unit is fixedly disposed in the fixed base 210 and is used to support the other end of the first lead screw 2521 that is away from the end connected to the motor 251.

[0059] Specifically, the first lead screw bearing unit 2523A includes a first lead screw bearing (not shown) and a corresponding first lead screw bearing seat (not shown). The inner ring of the first lead screw bearing is fixedly connected to the first lead screw 2521, the outer ring of the first lead screw bearing is fixedly connected to the first lead screw bearing seat, and the first lead screw bearing seat is fixedly connected to the gantry 220. The second lead screw bearing unit includes a second lead screw bearing (not shown) and a corresponding second lead screw bearing seat (not shown). The inner ring of the second lead screw bearing is fixedly connected to the first lead screw 2521, the outer ring of the second lead screw bearing is fixedly connected to the second lead screw bearing seat, and the second lead screw bearing seat is fixedly connected to the fixed base 210.

[0060] The clutch mechanism 100 is fixedly installed in the fixed base 210, and the first lead screw 2521 is the power input shaft; specifically, the first lead screw 2521 is fixedly connected to the inner ring of the first bearing 120, and the first lead screw 2521 is connected to the inner ring of the second bearing 140 via the first elongated keyway 141A.

[0061] In some embodiments, the clutch mechanism 100 may be separately located at the far end of the first lead screw 2521, away from the end connected to the motor 251, or it may replace the second lead screw bearing unit, which can be used to support the first lead screw 2521 and to switch the power transmission between the first transmission mechanism 252 and the reverse transmission mechanism 253.

[0062] In this embodiment, the clutch mechanism 100 is the second lead screw bearing unit, the clutch mechanism bearing seat 110 is the second lead screw bearing seat, and the first bearing 120 is the second lead screw bearing.

[0063] like Figure 7As shown, the reverse transmission mechanism 253 is a gear transmission mechanism, including a drive shaft 2531, a drive gear 2532 sleeved on and fixedly connected to the drive shaft 2531, a driven shaft 2533, and a driven gear 2534 sleeved on and fixedly connected to the driven shaft 2533; the drive gear 2532 and the driven gear 2534 are externally meshed.

[0064] The drive shaft 2531 is the power output shaft. Specifically, the drive shaft 2531 is connected to the inner ring key of the second bearing 140 through the second elongated keyway 141B. In some embodiments, the drive shaft 2531 can also be connected to the power output shaft using a coupling (not shown).

[0065] In order to support the drive shaft 2531, a drive shaft bearing unit 2535 is also included. The drive shaft bearing unit 2535 is fixedly disposed in the fixed base and is used to support the end of the drive shaft 2531 away from the connection with the second bearing 140.

[0066] Specifically, the drive shaft bearing unit 2535 includes a drive shaft bearing (not shown) and a drive shaft bearing housing (not shown); the inner ring of the drive shaft bearing is fixedly connected to one end of the drive shaft 2531 away from the end connected to the second bearing 140; the outer ring of the drive shaft bearing is fixedly connected to the drive shaft bearing housing, and the drive shaft bearing housing is fixedly connected to the fixed base 210.

[0067] In order to support the driven shaft 2533, a driven shaft bearing unit (not shown) is also included, which is fixedly installed in the fixed base;

[0068] Specifically, the driven shaft bearing unit includes a driven shaft bearing (not shown) and a driven shaft bearing housing (not shown); the inner ring of the driven shaft bearing is fixedly connected to the driven shaft 2533; the outer ring of the driven shaft bearing is fixedly connected to the driven shaft bearing housing, and the driven shaft bearing housing is fixedly connected to the fixed base 210.

[0069] To achieve smooth and reliable transmission, the driving gear 2532 and the driven gear 2534 have the same module and pressure angle, and the center distance is determined according to relevant design requirements to ensure that there will be no interference or excessive clearance during meshing.

[0070] To ensure that the rotational speeds of the drive shaft 2531 and the driven shaft 2533 are the same, the number of teeth of the drive gear 2532 and the driven gear 2534 are equal.

[0071] like Figure 6As shown, the second transmission mechanism 254 is a ball screw transmission mechanism, which includes a second screw 2541 and a second moving block 2542 that is sleeved on the second screw 2541 by a plurality of balls (not shown) and forms a helical pair with the second screw 2541; the second screw 2541 is fixedly connected to the driven shaft 2533, and the second moving block 2542 is fixedly connected to the lower clamping plate 230.

[0072] In some embodiments, the second lead screw 2541 and the driven shaft 2533 may be two separate shafts, with the second lead screw 2541 fixedly connected to the driven shaft 2533 via a coupling (not shown); in this embodiment, the second lead screw 2541 and the driven shaft 2533 are a single shaft, which is an integrally formed shaft.

[0073] When the drive shaft 2531 rotates, it drives the drive gear 2532 connected to it to rotate. Since the drive gear 2532 and the driven gear 2534 are in an external meshing relationship, the rotation of the drive gear 2532 will drive the driven gear 2534 to rotate in the opposite direction. The rotation of the driven gear 2534 is further transmitted to the second lead screw 2541 fixedly connected to it, causing the second lead screw 2541 to rotate accordingly. Driven by the second lead screw 2541, the second moving block 2542 moves linearly along the axial direction of the second lead screw 2541. Since the second moving block 2542 is fixedly connected to the lower clamping plate 230, it will further drive the lower clamping plate 230 to move linearly along the axial direction of the second lead screw 2541 on the fixed base 210.

[0074] Specifically, the second lead screw 2541 and the driven shaft 2533 are arranged in the same straight line.

[0075] Specifically, the second lead screw 2541 and the first lead screw 2521 are respectively disposed on both sides of the reverse transmission mechanism 253.

[0076] In some embodiments, the second moving block 2542 and the lower clamping plate 230 may be composed of multiple components or be a one-piece structure.

[0077] To support the second lead screw 2541, a second lead screw bearing unit group 2543 is also included, specifically comprising a third lead screw bearing unit 2543A and a fourth lead screw bearing unit 2543B. The third lead screw bearing unit 2543A and the fourth lead screw bearing unit 2543B are fixedly disposed within the fixed base 210. The third lead screw bearing unit 2543A is used to support the end of the second lead screw 2541 connected to the driven gear 2534; the fourth lead screw bearing unit 2543B is used to support the other end of the second lead screw 2541 away from the end connected to the driven gear 2534.

[0078] Specifically, the third lead screw bearing unit 2543A includes a third lead screw bearing (not shown) and a corresponding third lead screw bearing housing (not shown), and the fourth lead screw bearing unit 2543B includes a fourth lead screw bearing (not shown) and a corresponding fourth lead screw bearing housing (not shown); several keys are respectively provided at both ends of the second lead screw 2541, so as to connect with the inner ring of the third lead screw bearing and the inner ring of the fourth lead screw bearing;

[0079] To further simplify the structural volume in this application, in this embodiment, the third lead screw bearing unit 2543A also functions as a driven shaft bearing unit.

[0080] In order for the first moving block 2522 to move relative to each other in the vertical direction, the second lead screw 2541 is set in the vertical direction.

[0081] Working process: Motor 251 starts working, driving the first lead screw 2521 to rotate clockwise. Under the action of the first lead screw 2521, the upper clamping plate 240 moves downward in a straight line along the axial direction of the first lead screw 2521. When the upper clamping plate 240 moves to a certain position, the control system triggers the cylinder module in the clutch mechanism to work. At this time, the second bearing is connected to the drive shaft 2531 under the action of the cylinder module, and the rotation of the first lead screw 2521 can be transmitted to the drive shaft 2531 through the second bearing. The rotation of the drive shaft 2531 drives the drive gear 2532 to rotate clockwise. Since the drive gear 2532 and the driven gear 2534 are in an external meshing relationship, the driven gear 2534 will rotate counterclockwise. The counterclockwise rotation of the driven gear 2534 further drives the second lead screw 2541 to also rotate counterclockwise. Under the action of the second lead screw 2541, the lower clamping plate 230 moves upward in a straight line along the axial direction of the second lead screw 2541; as the upper clamping plate 240 moves downward and the lower clamping plate 230 moves upward, the two move towards each other, realizing the centering and clamping of the hose, and completing the entire clamping process.

[0082] This invention achieves precise linear motion of the clamping plates through a motor-driven lead screw transmission, and uses a cylinder module to control the clutch mechanism to complete flexible switching of power transmission. Combined with gear transmission, it achieves precise power conversion and direction control, ultimately realizing the opposite movement of the upper and lower clamping plates to complete the centering and clamping of the hose. This not only improves clamping accuracy and stability, but also reduces labor intensity and increases work efficiency through automated control. At the same time, it has the characteristics of compact structure and strong applicability, and can be widely used in a variety of scenarios requiring precise clamping.

[0083] Example 2

[0084] like Figure 8As shown, the structure of a clutch mechanism for two-shaft transmission in Embodiment 2 of this utility model is roughly the same as that in Embodiment 1, except that the second bearing 140 is included, and a bushing 150 is also included.

[0085] In this embodiment, the second bearing 140 is a standard rolling bearing component, specifically including an outer ring (not shown), rolling elements (not shown), and an inner ring (not shown). Its outer ring is fixedly connected to the piston rod 133, and its inner ring is fixedly connected to the bushing 150. The structure inside the bushing 150 is consistent with the structure of the inner ring of the second bearing 140, and is keyed to the external power input shaft and output shaft, respectively.

[0086] Compared to Example 1, this example further improves the applicability of the automatic coupling disengagement device and reduces production costs.
