A portable hydraulic shaft threader

Abstract

This invention relates to the field of shaft threading technology and discloses a portable hydraulic shaft threader, including a hydraulic push rod body. When the assembly shaft is jammed during insertion, the hydraulic pressure in the hydraulic chamber of the hydraulic push rod body rises sharply. Once the pressure exceeds the preset threshold of the relief valve, the relief valve automatically opens to divert pressure. Excess hydraulic oil is transported through a delivery pipe to the extrusion cover on the side wall of the connecting cover. The increased pressure inside the extrusion cover pushes the piston outward, and the synchronizing rod at the piston end moves in tandem, driving the swing arm to rotate around its rotation center. The swing arm, through the synchronizing shaft, drives the gear inside the positioning seat to rotate, ultimately rotating the positioning sleeve and the clamped assembly shaft to adjust its direction and precisely avoid the jammed position. The entire process requires no manual intervention, solving the problems of time-consuming and low-precision traditional manual adjustments. Simultaneously, the pressure diversion design avoids high-pressure damage to components, significantly improving assembly reliability.

Description

Technical Field

[0001] This invention belongs to the field of shaft threading technology, and more specifically, relates to a portable hydraulic shaft threader. Background Technology

[0002] In the field of mechanical assembly, the insertion and installation of assembly shafts is a core and common process in the assembly of various equipment, widely used in the production processes of many industries such as construction machinery, machine tools, and automotive parts. Its assembly efficiency and reliability not only directly determine the assembly cycle of a single piece of equipment, but also have a cascading effect on the capacity output and product delivery cycle of the entire production line, thus having a critical impact on enterprise production efficiency. Currently, the insertion and installation of assembly shafts in the industry relies on simple hydraulic auxiliary equipment with a simple structure. However, due to various factors such as deviations in the machining accuracy of the assembly surface, obstruction from foreign objects during assembly, and slight deviations in the insertion angle, the assembly shaft is highly susceptible to jamming during the insertion process.

[0003] When jamming occurs, operators often resort to forcibly increasing the thrust of the hydraulic equipment in an attempt to overcome the obstruction and complete the connection in order to continue assembly. This operation not only fails to effectively resolve the jamming problem but also has a direct negative impact on the hydraulic push rod, potentially leading to malfunctions such as damage to the hydraulic push rod seals, deformation of the push rod body, and leakage in the internal hydraulic cavity. This, in turn, shortens the equipment's lifespan and increases maintenance costs and the risk of production interruption.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0006] A portable hydraulic axle inserter includes a hydraulic push rod body.

[0007] The output end of the hydraulic push rod body is equipped with a connecting cover, and a positioning sleeve is rotatably installed at the end of the connecting cover. A clamping component is installed on the positioning sleeve, and the clamping component is used to clamp the assembly shaft. The hydraulic push rod body is used to push the assembly shaft to be inserted into the designated work position.

[0008] The hydraulic chamber sidewall of the hydraulic push rod body is connected to an overflow valve, which is connected to the extrusion cover installed on the sidewall of the connecting cover. When jamming occurs during the assembly shaft insertion process, the internal pressure of the hydraulic push rod body increases, and the excess hydraulic oil is delivered to the extrusion cover through the overflow valve.

[0009] A piston is slidably disposed inside the extrusion cover. A synchronizing rod is installed at the end of the piston. The synchronizing rod is slidably connected to a swing arm that rotates on the side wall of the connecting cover. A transmission gear is installed at the rotation center of the swing arm. A reversing gear is meshed on the side wall of the transmission gear. The rotation center of the reversing gear is connected to the rotation center of the positioning sleeve. When excess hydraulic oil squeezes the piston to slide, it drives the positioning sleeve and the connected assembly shaft to rotate, causing the assembly shaft to change direction during the assembly process.

[0010] In a preferred embodiment of the present invention, a hydraulic pump is installed on the outer shell of the hydraulic push rod body. The output end of the hydraulic pump is connected to the hydraulic chamber of the hydraulic push rod body, and the input end of the hydraulic pump is connected to the hydraulic oil tank. A delivery pipe is installed on the overflow valve. The delivery pipe is a flexible hose. The end of the delivery pipe is connected to the extrusion cover. A discharge pipe is installed at one end of the delivery pipe, and a valve is installed on the discharge pipe.

[0011] In a preferred embodiment of the present invention, a mounting plate is installed on the outer end of the hydraulic push rod body. A pair of mounting ears are welded on the mounting plate. The mounting ears are triangular in shape, and a connecting shaft is installed through the mounting ears. The connecting shaft facilitates the connection between the mounting ears and the external structure and is used to position the working position of the hydraulic push rod body.

[0012] In a preferred embodiment of the present invention, a sleeve rod is installed on the back of the connecting cover, and a sleeve hole is opened inside the sleeve rod. The sleeve hole is inserted into the output end of the hydraulic push rod body. Multiple pairs of locking bolts are screwed through and installed on the sleeve rod, and the bottom of the locking bolts is pressed against the side wall of the output end of the hydraulic push rod body.

[0013] In a preferred embodiment of the present invention, a guide ring is installed on the back of the positioning sleeve, the guide ring is movably inserted into the inside of the connecting cover, a slide rail is installed on the guide ring, and a slide groove is formed on the inner side wall of the connecting cover, the slide groove being slidably connected to the slide rail.

[0014] In a preferred embodiment of the present invention, the clamping assembly includes three pairs of push rods, which are evenly inserted around the positioning sleeve. Each push rod has a top plate at its end and a ball bearing at its top. A guide sleeve is rotatably mounted on the outer wall of the positioning sleeve. Three pairs of ramps are installed inside the guide sleeve. The ramps are slidably connected to the corresponding ball bearings. After the guide sleeve drives the ramps to rotate, it drives the push rods to move towards the center and positions the assembly shaft.

[0015] In a preferred embodiment of the present invention, a baffle is installed on the outer wall of the push rod, a compression spring is sleeved on the push rod, one end of the compression spring is engaged with the baffle, and the other end of the compression spring is engaged with the side wall of the positioning sleeve. A sliding plate is installed on the back of the guide sleeve, a guide block is installed on the sliding plate, a guide groove is opened on the positioning sleeve, the guide block is slidably disposed in the guide groove, and a locking bolt is screwed onto the sliding plate, with the end of the locking bolt fitting against the surface of the positioning sleeve.

[0016] In a preferred embodiment of the present invention, a positioning frame is installed on the extrusion cover, the positioning frame is movably connected to the synchronizing rod, a cover plate is installed on the extrusion cover, a back plate is installed on the piston sidewall, and a return spring is sleeved on the synchronizing rod, one end of the return spring is snapped into the back plate, and the other end of the return spring is snapped into the cover plate.

[0017] In a preferred embodiment of the present invention, a positioning seat is installed inside the connecting cover, and a synchronous shaft is rotatably installed inside the positioning seat. One end of the synchronous shaft is connected to the rotation center of the swing arm. A strip groove is provided on the swing arm, and a slide rod is slidably arranged on the strip groove. A fixing block is installed on the slide rod, and the end of the fixing block is installed at the end of the synchronous rod.

[0018] In a preferred embodiment of the present invention, the other end of the synchronous shaft is connected to the rotation center of the transmission gear, and the radius of the transmission gear is greater than the radius of the reversing gear. The transmission gear and the reversing gear cooperate with each other to increase the number of rotations of the reversing gear and the positioning sleeve.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. When the assembly shaft is jammed, the hydraulic pressure in the hydraulic chamber of the hydraulic push rod body will rise sharply. Once the pressure exceeds the preset threshold of the relief valve, the relief valve will automatically open to achieve pressure diversion. The excess hydraulic oil is transported to the extrusion cover on the side wall of the connecting cover through the delivery pipe. After the pressure in the extrusion cover rises, it pushes the piston to slide outward. The synchronous rod at the end of the piston will then move in tandem, driving the swing arm to rotate around its rotation center. The swing arm drives the gear in the positioning seat to rotate through the synchronous shaft, which in turn drives the positioning sleeve and the clamped assembly shaft to rotate and adjust the direction, accurately avoiding the jamming position. The whole process does not require manual intervention, which solves the problems of long time and low accuracy of traditional manual adjustment. At the same time, the pressure diversion design avoids high pressure damage to components and greatly improves the reliability of assembly.

[0021] 2. This invention adopts an integrated and compact structure, with core components such as the hydraulic push rod body, connecting cover, and extrusion cover modularly assembled. It is small in size and lightweight, making it easy for operators to carry and transport. Furthermore, it does not require external large auxiliary equipment and can complete the operation solely with its integrated hydraulic system, further enhancing its portability and making assembly shaft insertion operations under complex working conditions more flexible and efficient.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0035] Example 1, as Figures 1 to 9 As shown, a portable hydraulic shaft inserter includes a hydraulic push rod body 1, a connecting cover 6 installed at the output end of the hydraulic push rod body 1, a positioning sleeve 9 rotatably installed at the end of the connecting cover 6, a clamping assembly installed on the positioning sleeve 9, and the clamping assembly is used to clamp the assembly shaft, and the hydraulic push rod body 1 is used to push the assembly shaft to be inserted into the designated work position.

[0036] The hydraulic chamber sidewall of the hydraulic push rod body 1 is connected to an overflow valve 23. The overflow valve 23 is connected to the extrusion cover 25 installed on the sidewall of the connecting cover 6. When jamming occurs during the assembly shaft insertion process, the internal pressure of the hydraulic push rod body 1 increases, and the excess hydraulic oil is transported to the extrusion cover 25 through the overflow valve 23.

[0037] A piston 27 is slidably disposed inside the extrusion cover 25. A synchronizing rod 29 is installed at the end of the piston 27. The synchronizing rod 29 is slidably connected to the swing arm 33 that rotates on the side wall of the connecting cover 6. A transmission gear 37 is installed at the rotation center of the swing arm 33. A reversing gear 38 is meshed on the side wall of the transmission gear 37. The rotation center of the reversing gear 38 is connected to the rotation center of the positioning sleeve 9. When excess hydraulic oil squeezes the piston 27 to slide, it drives the positioning sleeve 9 and the connected assembly shaft to rotate, causing the assembly shaft to change direction during the assembly process.

[0038] like Figures 1 to 9As shown, in a specific embodiment, a hydraulic pump 5 is installed on the outer shell of the hydraulic push rod body 1. The output end of the hydraulic pump 5 is connected to the hydraulic chamber of the hydraulic push rod body 1, and the input end of the hydraulic pump 5 is connected to the hydraulic oil tank. A delivery pipe 24 is installed on the overflow valve 23. The delivery pipe 24 is a flexible hose, and its end is connected to the extrusion cover 25. A discharge pipe is installed at one end of the delivery pipe 24, and a valve is installed on the discharge pipe. The hydraulic pump 5 provides a continuous power source for the hydraulic push rod body 1. The flexible delivery pipe 24 adapts to the relative positions of the components. The discharge pipe and valve facilitate the discharge of hydraulic oil and system reset, ensuring the stability of the hydraulic system's power supply and the convenience of operation.

[0039] like Figures 1 to 9 As shown, furthermore, a mounting plate 2 is installed on the outer end of the hydraulic push rod body 1. A pair of mounting ears 3 are welded onto the mounting plate 2. The mounting ears 3 are triangular in shape, and a connecting shaft 4 is installed through the mounting ears 3. The connecting shaft 4 facilitates the connection between the mounting ears 3 and the external structure, and is used to position the hydraulic push rod body 1 in its working position. The triangular structure of the mounting ears 3 has high structural strength, and the welded connection between the mounting plate 2 and the mounting ears 3 is stable. Together with the connecting shaft 4, the hydraulic push rod body 1 can be quickly positioned and fixed to the external structure, ensuring the positional stability of the device during operation and improving installation efficiency.

[0040] Example 2 differs from the above examples in that: Figures 1 to 9 As shown, a sleeve rod 7 is installed on the back of the connecting cover 6. A sleeve hole 8 is provided inside the sleeve rod 7, which is inserted into the output end of the hydraulic push rod body 1. Multiple pairs of locking bolts are screwed through and tightened onto the sleeve rod 7, with the bottom of the locking bolts pressing against the side wall of the output end of the hydraulic push rod body 1. By connecting the sleeve rod 7 to the output end of the hydraulic push rod body 1 through the sleeve hole 8 and then locking it with the locking bolts, a detachable connection between the connecting cover 6 and the hydraulic push rod body 1 is achieved. This facilitates component maintenance and replacement while ensuring the connection's robustness.

[0041] like Figures 1 to 9 As shown in the specific embodiment, a guide ring 10 is installed on the back of the positioning sleeve 9. The guide ring 10 is movably inserted into the inside of the connecting cover 6. A slide rail 11 is installed on the guide ring 10. A slide groove 12 is formed on the inner side wall of the connecting cover 6, and the slide groove 12 is slidably connected to the slide rail 11. The insertion and engagement of the guide ring 10 and the connecting cover 6 provides the mounting base for the positioning sleeve 9. The sliding engagement of the slide rail 11 and the slide groove 12 ensures the coaxiality and stability of the positioning sleeve 9 during rotation, avoids offset during rotation, and improves the accuracy of the assembly shaft angle adjustment.

[0042] like Figures 1 to 9As shown, the clamping assembly further includes three pairs of push rods 13, which are evenly inserted around the positioning sleeve 9. Each push rod 13 has a top plate 14 installed at its end, and a ball bearing 17 is installed on the top of the push rod 13. A guide sleeve 18 is rotatably installed on the outer wall of the positioning sleeve 9. Three pairs of ramps 19 are installed inside the guide sleeve 18. The ramps 19 are slidably connected to the corresponding balls 17. After the guide sleeve 18 drives the ramps 19 to rotate, it drives the push rods 13 to move towards the center and positions the assembly shaft. The evenly surrounding push rods 13 can achieve centering clamping of the assembly shaft. The top plate 14 increases the contact area with the assembly shaft, the balls 17 reduce the sliding friction with the ramps 19, and the driving method of the guide sleeve 18 driving the ramps 19 to rotate is convenient to operate and can quickly achieve synchronous movement of the push rods 13, ensuring the stability and centering accuracy of the clamping.

[0043] like Figures 1 to 9 As shown, further, a baffle 15 is installed on the outer wall of the push rod 13, and a compression spring 16 is sleeved on the push rod 13. One end of the compression spring 16 is engaged with the baffle 15, and the other end is engaged with the side wall of the positioning sleeve 9. A slide plate 20 is installed on the back of the guide sleeve 18, and a guide block 21 is installed on the slide plate 20. A guide groove 22 is opened on the positioning sleeve 9, and the guide block 21 is slidably disposed in the guide groove 22. A locking bolt is screwed onto the slide plate 20, and the end of the locking bolt is in contact with the surface of the positioning sleeve 9. The compression spring 16 provides the return force to the push rod 13 through the baffle 15, which facilitates the quick return of the push rod 13 after clamping. The cooperation between the guide block 21 and the guide groove 22 ensures the stability of the trajectory when the guide sleeve 18 rotates. The locking bolt can fix the position of the guide sleeve 18, prevent the guide sleeve 18 from loosening during clamping, and ensure the reliability of the clamping state.

[0044] Example 3, based on the above examples and the differences between this example and the following: Figures 1 to 9 As shown, a positioning frame 26 is installed on the extrusion cover 25, and the positioning frame 26 movably passes through the synchronizing rod 29. A cover plate 30 is installed on the extrusion cover 25, and a back plate 28 is installed on the side wall of the piston 27. A return spring 31 is sleeved on the synchronizing rod 29, with one end of the return spring 31 engaged with the back plate 28 and the other end engaged with the cover plate 30. The positioning frame 26 guides the movement of the synchronizing rod 29, ensuring its linear motion accuracy. The return spring 31, through the cooperation of the back plate 28 and the cover plate 30, can drive the piston 27 and the synchronizing rod 29 to quickly return to their original positions after the adjustment is locked, ensuring the smooth operation of the adaptive adjustment cycle.

[0045] like Figures 1 to 9As shown, in a specific embodiment, a positioning seat 36 is installed inside the connecting cover 6, and a synchronous shaft 35 is rotatably mounted inside the positioning seat 36. One end of the synchronous shaft 35 is connected to the rotation center of the swing arm 33. A strip groove 34 is provided on the swing arm 33, and a slide rod 39 is slidably arranged on the strip groove 34. A fixing block 32 is installed on the slide rod 39, and the end of the fixing block 32 is installed at the end of the synchronous rod 29. The positioning seat 36 provides stable rotational support for the synchronous shaft 35. The synchronous shaft 35 realizes the transmission of rotational power of the swing arm 33. The sliding cooperation between the strip groove 34 and the slide rod 39 converts the linear motion of the synchronous rod 29 into the rotational motion of the swing arm 33. The fixing block 32 ensures the firmness of the connection between the synchronous rod 29 and the slide rod 39, and improves the stability of power transmission.

[0046] like Figures 1 to 9 As shown, furthermore, the other end of the synchronous shaft 35 is connected to the rotation center of the transmission gear 37, and the radius of the transmission gear 37 is larger than the radius of the reversing gear 38. The transmission gear 37 and the reversing gear 38 cooperate to increase the number of rotations of the reversing gear 38 and the positioning sleeve 9. The synchronous shaft 35 realizes the power synchronization between the swing arm 33 and the transmission gear 37. The radius difference design between the transmission gear 37 and the reversing gear 38 can amplify the number of rotations, allowing the positioning sleeve 9 to drive the assembly shaft to produce a more obvious angle adjustment, making it easier to avoid jamming positions and improving the efficiency of jamming fault resolution.

[0047] The implementation principle of the portable hydraulic shaft inserter of the present invention is as follows: First, the device is installed, positioned, and the assembly shaft is clamped and fixed. The operator connects and fixes the entire device to the external structure through the mounting plate 2 and the welded triangular mounting lug 3 on the outer shell of the hydraulic push rod body 1, and uses the connecting shaft 4 to ensure that the working position of the hydraulic push rod body 1 is accurately positioned, providing a stable foundation for subsequent pushing actions. Then, the assembly shaft is clamped and placed in the positioning sleeve 9. By rotating the guide sleeve 18 on the outer wall of the positioning sleeve 9, the three pairs of ramps 19 inside the guide sleeve 18 slide relative to the ball bearings 17 at the top of the push rod 13. The inclined structure of the ramps 19 drives the three pairs of evenly surrounding push rods 13 to move synchronously towards the center until the top plate 14 at the end of the push rod 13 is tightly fitted with the outer wall of the assembly shaft, thus achieving centering and clamping of the assembly shaft. During this process, the compression spring 16 between the baffle 15 on the outer side wall of the push rod 13 and the side wall of the positioning sleeve 9 is in a compressed state, providing elastic force for the subsequent reset of the push rod 13. After clamping is completed, the locking bolt on the slide plate 20 is tightened to restrict the rotation of the guide sleeve 18 and ensure that the clamping state is stable.

[0048] After positioning and clamping are completed, the shaft insertion and pushing process is initiated. The operator controls the hydraulic pump 5 to operate, drawing hydraulic oil from the hydraulic oil tank and delivering it to the hydraulic chamber of the hydraulic push rod body 1. The pressure in the hydraulic chamber increases, pushing the output end out. Through the connecting cover 6, it drives the positioning sleeve 9 and the clamped assembly shaft to move to the designated position, realizing the insertion and pushing of the assembly shaft. During normal pushing, the pressure in the hydraulic chamber is maintained within a stable range, and the overflow valve 23 is in the closed state to ensure stable output of thrust from the hydraulic push rod body 1. If the assembly shaft encounters resistance and jams during insertion, the pressure in the hydraulic chamber of the hydraulic push rod body 1 will rise rapidly. When the pressure exceeds the set threshold of the overflow valve 23, the overflow valve 23 automatically opens, delivering excess hydraulic oil in the hydraulic chamber through the delivery pipe 24 to the inside of the extrusion cover 25 installed on the side wall of the connecting cover 6, thereby diverting and releasing pressure and preventing damage to components due to excessive pressure.

[0049] In the adaptive adjustment phase after entering the jammed state, the hydraulic oil pressure inside the extrusion cover 25 increases, pushing the internally sliding piston 27 to slide outward. The synchronizing rod 29 at the end of the piston 27 moves synchronously, and the fixing block 32 at the end of the synchronizing rod 29 drives the sliding rod 39 to slide in the strip groove 34 of the swing arm 33, thereby driving the swing arm 33 to rotate around its rotation center. The rotation center of the swing arm 33 is connected to the transmission gear 37 in the positioning seat 36 through the synchronizing shaft 35. When the swing arm 33 rotates, it drives the transmission gear 37 to rotate synchronously. The transmission gear 37 and the reversing gear 38 meshing with the side wall generate transmission. Since the rotation center of the reversing gear 38 is connected to the rotation center of the positioning sleeve 9, and the radius of the transmission gear 37 is larger than the radius of the reversing gear 38, the number of rotations of the reversing gear 38 and the positioning sleeve 9 can be increased through the design of the gear transmission ratio. This causes the positioning sleeve 9 to drive the clamped assembly shaft to rotate at an angle, changing the insertion direction of the assembly shaft, thereby avoiding the jammed position and realizing adaptive adjustment in the jammed state. During this process, the positioning frame 26 on the extrusion cover 25 guides the synchronizing rod 29 to ensure its linear movement accuracy. At the same time, the return spring 31 sleeved on the synchronizing rod 29 is compressed by the back plate 28 and the cover plate 30 to store elastic force for subsequent structural reset.

[0050] After the assembly shaft is rotated and adjusted, the jamming fault is resolved. The hydraulic pressure in the hydraulic chamber of the hydraulic push rod body 1 decreases, the overflow valve 23 closes to stop supplying oil to the extrusion cover 25, and the hydraulic oil on the delivery pipe 24 is discharged through the discharge pipe. At this time, the return spring 31 releases its elastic force to push the piston 27 to slide in the opposite direction, allowing the hydraulic oil in the extrusion cover 25 to flow back through the delivery pipe 24. The synchronizing rod 29 drives the swing arm 33 to rotate in the opposite direction, and the positioning sleeve 9 is restored to its initial angle through gear transmission, completing one adaptive adjustment cycle. After the shaft is inserted, the locking bolt on the slide plate 20 is loosened, the compression spring 16 pushes the push rod 13 to reset, and the top plate 14 disengages from the assembly shaft, thus completing the entire shaft insertion operation. The entire implementation process achieves efficient and stable insertion of the assembly shaft through the coordinated cooperation of the mechanical structure and the hydraulic system, while improving the operational reliability under complex working conditions through the adaptive adjustment mechanism.
