Description

Technical Field

[0001] This invention relates to the field of mechanical assembly auxiliary equipment technology, specifically a gearbox output shaft insert clamp. Background Technology

[0002] In the manufacturing process of motors and gearboxes, the assembly of the output shaft assembly is one of the key steps. To prevent axial slippage of internal transmission parts and ensure the stability of mechanical transmission, a retaining ring needs to be pressed into a designated position on the output shaft for axial restraint. Currently, many production workshops still use traditional manual operation methods for this process. Operators need to use special retaining ring pliers, rely on hand grip to pry open the retaining ring, visually align it with the retaining ring groove on the output shaft, and then use wrist strength to push the retaining ring into the groove to complete the assembly.

[0003] Manual pressing methods have certain limitations in actual production. Because it's difficult for a human hand to maintain a consistently horizontal and straight movement, uneven force application or obstructed vision can easily occur during continuous operation, causing the retaining ring to tilt at an angle during the pushing-in phase. Once the pushing direction deviates from the horizontal plane, the retaining ring not only fails to smoothly engage in the positioning groove but also easily interferes with the shaft surface, potentially leading to improper stress on the retaining ring itself and plastic deformation. This reduces the locking strength of the parts and increases the scrap rate.

[0004] On the other hand, the internal structural clearances of the gearbox and motor further increase the difficulty of assembly. Before the retaining ring is installed in place, the output shaft usually has axial movement space, causing the height reference of the retaining ring groove to be unstable. When assembling with clamps, operators find it difficult to simultaneously perform the downward pressing of the output shaft and the horizontal pushing of the retaining ring. The unstable assembly target position requires operators to spend more time on alignment and probing, which not only increases labor intensity but also makes it difficult to effectively guarantee the overall assembly efficiency and product consistency of the production line. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a gearbox output shaft retaining ring clamp, which solves the problems of retaining ring tilting and deformation caused by uneven force application and trajectory deviation during traditional manual assembly, as well as the problem of inconsistent retaining ring groove height reference and difficulty in precise alignment and pressing due to axial movement of the gearbox output shaft.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a gearbox output shaft insert clamp, including a rubber foot pad, a base plate fixedly connected to its top, a power mechanism installed on the top of the base plate, a first connector connected to the output end of the power mechanism, a transmission mechanism connected to the bottom of the first connector, and a product disposed on one side of the transmission mechanism; The transmission mechanism includes a material channel, a fastener is provided inside the material channel, a support base is fixedly connected to the outside of the material channel, a motor base is fixedly connected to the top of the support base, and a product is movably inserted inside the motor base.

[0007] Preferably, the power mechanism includes a bracket fixed to the top of the base plate, a cylinder mounted on the top of the bracket, a second connector fixedly connected to the output end of the cylinder, the front end of the second connector engaging with the first connector, a retaining clamp fixedly connected to the bottom of the first connector, and an accessory fixedly connected to the outer front end of the retaining clamp.

[0008] Preferably, the transmission mechanism further includes a slide rail fixed to the top of the base plate, a slider slidably connected to the top of the slide rail, and the bottom of the buckle clamp fixedly mounted on the slider, so that the buckle clamp and the accessory reciprocate linearly along the slide rail with the slider.

[0009] Preferably, the outer wall of the product is provided with a buckle groove, and the buckle clamp is provided with a C-shaped locking position for accommodating the buckle piece at one end facing the product. The buckle clamp pushes the buckle piece horizontally into the buckle groove through the C-shaped locking position.

[0010] Preferably, the slide rail is disposed between the material channel slide rail and the support slide rail, and the extension direction of the cylinder and the extension direction of the slide rail are both perpendicular to the output shaft axis of the product.

[0011] Preferably, a magnet is provided directly below the material channel to attract the retaining ring inside the material channel downward by magnetic force. A magnetic column is also provided directly below the interior of the motor base to attract the output shaft of the product downward, so that the output shaft is pulled down and the retaining ring groove required for assembly is exposed.

[0012] Preferably, the material channel has a vertically downward-facing storage trough inside, and multiple buckle members are stacked vertically inside the storage trough.

[0013] Preferably, the top of the first connector is provided with a U-shaped groove, and the second connector is inserted into the U-shaped groove to form a movable connection, which is used to transmit the horizontal thrust of the cylinder to the retaining clamp.

[0014] Preferably, the product includes a brushed DC motor and a gearbox, the motor is mounted at the bottom of the gearbox, the bottom of the motor is provided with a downwardly extending output shaft, and the retaining ring groove is formed on the output shaft.

[0015] Preferably, the thickness of the snap ring clamp is adapted to the width of the snap ring groove. During pressing, the inner wall of the accessory abuts against the outer side of the snap ring to help limit the position of the snap ring and push the snap ring into the snap ring groove with the snap ring clamp.

[0016] This invention provides a gearbox output shaft clamping ring fixture. It has the following advantages: 1. This invention uses a cylinder on the base plate to drive the retaining ring clamp to reciprocate linearly along a slide rail, transforming traditional manual pressing into a semi-automated operation. The thrust of the cylinder works in conjunction with the guidance of the slide rail, allowing the retaining ring to be pushed into the retaining ring groove of the output shaft along a fixed trajectory. This reduces errors caused by reliance on operator experience and hand strength, avoids skewing or jamming that occurs during manual operation, and improves the consistency of pressing operations and product qualification rate.

[0017] 2. This invention simplifies material feeding by using a vertically arranged feed channel in conjunction with the movement of the snap ring clamp. The snap ring clamp has a C-shaped slot on the side facing the product. When the cylinder moves the snap ring clamp back below the feed channel, the bottom snap ring in the channel falls directly into the C-shaped slot due to gravity. This combines the resetting of the actuator with the material handling action, eliminating the need for an additional feeding robot or material distribution assembly, reducing the overall manufacturing and maintenance costs of the fixture, and minimizing potential mechanical failure points.

[0018] 3. This invention utilizes a magnetic column installed inside the motor base, directly beneath the product. After the product is placed inside, the magnetic force of the column pulls the output shaft of the gearbox downwards, thus limiting axial movement of the output shaft during assembly. This ensures that the retaining ring groove on the output shaft remains consistently at a height level with the retaining ring clamp. This structure eliminates the need for additional clamping mechanisms such as cylinders above the equipment to achieve precise axial positioning, reducing the difficulty of fixture control and ensuring accurate press-fitting.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 - Appendix Figure 3 This invention provides a gearbox output shaft clamping fixture, the bottom of which includes multiple rubber feet 1. The rubber feet 1 are fixed at the four corners of the bottom, contacting the worktable surface and providing physical support. During the operation of the mechanical equipment, the reciprocating motion of the cylinder 9 generates a certain impact force. The rubber material absorbs high-frequency vibrations through its own elastic deformation, preventing the fixture from slipping on the worktable. A base plate 2 is fixedly connected to the top of the rubber feet 1. The base plate 2 is made of metal sheet with a smooth surface and is electroplated for rust prevention. The base plate 2 serves as the installation reference for each moving and stationary module, ensuring a unified height reference surface between mechanisms installed on the same plane. The rear top of the base plate 2 is designated as a power area, where a power mechanism is installed. This power mechanism provides the driving force for the fixture to perform linear reciprocating motion for pushing and retracting actions. The output end of the power mechanism is connected to a first connector 7, which transmits the linear force output from the power source forward along the horizontal centerline. A transmission mechanism is connected to the bottom front end of the first connector 7. This transmission mechanism is responsible for guiding and conveying materials and performing actual assembly operations during the fixture's operating cycle. A product 12, which is the object of the processing operation, is positioned on one front side of the transmission mechanism.

[0023] The transmission mechanism includes a vertically arranged material channel 3 in the material feeding stage. The material channel 3 is fixed to the front end of the platform in a column structure, providing a storage and guide channel for the parts to be assembled before entering the assembly station. The interior of the material channel 3 has a vertically downward-facing storage trough according to the outer dimensions of the retainer, and the retainer 11 is placed inside the storage trough. A support base 14 is fixedly connected to the adjacent area on the outer side of the material channel 3. The support base 14 is a base structure, its lower end anchored to the base plate 2 by fasteners, providing the necessary foundation height for placing the product 12, ensuring that the processing position of the product 12 is on the same straight line as the working plane of the rear transmission mechanism. A motor base 13 is fixedly connected to the top of the support base 14 by screws. The motor base 13 has a countersunk hole machined inside, matching the outer diameter of the gearbox housing, used to support and restrict the radial and circumferential movement of the gearbox housing. The product 12 moves through the interior of the motor base 13. The top edge of the positioning countersunk hole is machined with a guide chamfer, which makes it easy for operators to smoothly insert product 12 into the hole when loading and unloading on the production line.

[0024] Please see the appendix Figure 2 - Appendix Figure 4 In a preferred embodiment of the present invention, the rear power mechanism includes a bracket 8 fixed to the top of the base plate 2. The bracket 8 is a solid metal block structure, and its main function is to adjust and raise the height of the drive element in the vertical direction so that the height of its thrust output shaft is at the same level as the height of the front retaining ring groove 16. A cylinder 9 is bolted to the top of the bracket 8. The cylinder 9 is connected to the plant's air source and control solenoid valve through an external air pipe to provide linear thrust in the horizontal direction. The output end of the cylinder 9 is a threaded push rod, and a second connector 10 is fixedly connected to its end. The front end of the second connector 10 engages with the first connector 7.

[0025] The snap-fit ​​structure is designed to solve the over-positioning problem in mechanical equipment. Specifically, the top of the first connector 7 has an upward-opening U-shaped slot, and the second connector 10 is an inverted T-shaped or flanged cylinder that snaps into the U-shaped slot from top to bottom to form a movable connection. The U-shaped slot and the second connector 10 together form a floating joint, stably transmitting the horizontal thrust of the cylinder 9 to the front retaining clamp 6 while allowing for small vertical and horizontal clearances to absorb assembly coaxiality errors during operation. The bottom plane of the first connector 7 is fixedly connected to the retaining clamp 6, which, as a core component in direct contact with the material, supports the retaining ring 11 to be assembled. An accessory 5 is fixedly connected to the outer front end of the retaining clamp 6. The accessory 5 is positioned by pins and secured with bolts on the side of the retaining clamp 6, assisting in pushing the material during assembly and forming a force-bearing entity with the retaining clamp 6.

[0026] Please see the appendix Figure 3 - Appendix Figure 5In a preferred embodiment of the present invention, the transmission mechanism further includes a slide rail 4 fixed to the top middle section of the base plate 2. The slide rail 4 is typically an industrial linear guide with an internal ball bearing circulation structure, capable of withstanding loads in multiple directions and providing low-friction linear motion guidance to prevent lateral deviation of the push rod under pressure during press-fitting. The bottom of the slide rail 4 is fastened to the surface of the base plate 2 by countersunk screws. A suitable slider is slidably connected to the top of the slide rail 4, and the bottom of the retaining clamp 6 is fixedly mounted on the slider via a connecting plate or directly through a screw hole, allowing the retaining clamp 6 and accessory 5 to detach from the friction of the base plate 2 surface and reciprocate linearly along the slide rail 4 with the slider. A retaining groove 16 for fixing parts is provided on the output shaft at the junction of the gearbox and the motor on the outer wall of the product 12. The purpose of the assembly process is to insert the retaining clamp 11 into this groove.

[0027] To facilitate assembly, the end of the clamp 6 facing the product 12 has a C-shaped locking slot for accommodating the clamp 11. The inner diameter of the C-shaped locking slot matches the outer diameter of the clamp in its free state. The working part of the clamp 6 is milled to match the width of the clamp groove 16, and a tolerance clearance is provided to ensure that the front end of the clamp 6 can partially penetrate or be flush with the upper and lower edges of the clamp groove 16. During the pressing action, the inner wall of the fitting 5 abuts against the outer arc surface of the clamp 11. Since the fitting 5 is fixed to one side of the clamp 6, it forms a blocking wall behind the clamp, which helps to limit the retraction position of the clamp 11 when subjected to forward resistance. Under the pushing force of the fitting 5, the clamp 6, in conjunction with the C-shaped locking slot, pushes the clamp 11 forward, forcing the clamp to be horizontally locked into the clamp groove 16.

[0028] Please see the appendix Figure 1 and attached Figure 2In a preferred embodiment of the present invention, a magnet is provided in the feeding area, directly below the material channel 3, corresponding to the bottom of the storage tank. This magnet is embedded in the base of the material channel 3 and is used to attract the bottommost retaining ring 11 within the material channel 3 using downward magnetic force. At the moment of gravity-driven material drop, gravity alone can easily cause the small retaining ring to shift due to airflow or friction. Here, magnetic force is used to guide the bottommost retaining ring to overcome the inner wall resistance and quickly move downwards into place, preventing it from flipping or getting stuck during descent. Furthermore, in the positioning area, a magnetic column 15 is also provided inside the motor base 13, directly opposite the bottom of the product 12. Conventionally, there is a normal clearance between the gears and bearings inside the product 12, causing the output shaft to float up and down. When placed in the fixture, the height of the retaining ring groove 16 cannot be fixed. The magnetic column 15 is used to attract the magnetically conductive output shaft inside the product 12 downwards. When the product 12 is placed in the motor base 13, the output shaft is pulled downwards by magnetic force to the bottom, exposing the retaining ring groove 16 required for assembly. Without adding any external mechanical clamping mechanism, axial forced stretching positioning before assembly is achieved, limiting axial movement caused by lateral thrust during press fitting.

[0029] Please see the appendix Figure 2 and attached Figure 3 In a preferred embodiment of the present invention, the slide rail 4 is spatially positioned between the material channel 3 and the rear support 8. Product 12 is a complete assembly including a brushed DC motor and a gearbox. The motor is mounted at the bottom of the gearbox, and a downward-extending metal output shaft is located at the bottom of the motor. The aforementioned retaining ring groove 16 is cut into the cylindrical surface of the output shaft. The telescopic axis direction of the cylinder 9 during installation and the longitudinal extension direction of the slide rail 4 are both perpendicular to the axis of the output shaft when product 12 is placed upright. This perpendicular relationship ensures that the retaining ring moves tangentially horizontally when entering the retaining ring groove 16, preventing one side of the retaining ring from entering the groove first while the other side tilts up, allowing the retaining ring to be smoothly pushed into the groove horizontally after being subjected to force.

[0030] Please see the appendix Figure 2In a preferred embodiment of the present invention, a vertically downward storage trough is provided inside the material channel 3. The inner wall of the storage trough is polished smooth to reduce friction and is used to accommodate a batch of buckle parts 11 to be assembled. Multiple buckle parts 11 are arranged flat and stacked in the storage trough. When an assembly cycle ends, the cylinder 9 retracts and pulls the connecting assembly, causing the slider and buckle clamp 6 to retract along the slide rail 4. When the front end of the buckle clamp 6 retracts to directly below the material channel 3, space is made above the buckle clamp 6, and the buckle part 11 at the bottom of the storage trough loses its original support below. Under the combined action of its own weight and the attraction of the magnet at the bottom directly below, it falls vertically downward into the C-shaped slot reserved in the buckle clamp 6. When the cylinder 9 extends again, the side wall of the accessory 5 will push the newly fallen buckle forward, thereby combining the reset action of the cylinder 9 with the next material picking action to complete the automatic material replenishment when the clamp retracts.

[0031] Working Principle: During the preparation phase before equipment startup, the operator needs to inspect the entire fixture. First, connect the external pneumatic circuit and set the pneumatic pressure entering cylinder 9 to the range that meets the clamping force requirements of this model of buckle through the pneumatic pressure regulating valve at the front end of the equipment. Place multiple C-shaped buckle parts 11 to be assembled flatly into the material channel 3 of the transmission mechanism in sequence. The buckles are restricted in the vertically downward storage trough inside the material channel 3, and slide in a stacked state. The bottom buckle rests against the upper plane or support structure of the buckle clamp 6, waiting to fall.

[0032] During operation, the operator uses manual labor or auxiliary handling tools to vertically place the product 12, which includes the motor and gearbox, into the positioning hole of the motor mount 13 above the front support 14 of the base plate 2. After the product 12 is placed in, it is radially and circumferentially fixed by the constraint of the outer shell of the motor mount 13. At the moment of placement, the output shaft at the bottom of the product 12 is attracted by the magnetic column 15 located directly below the inside of the motor mount 13. The magnetic force overcomes the friction between the gears inside the gearbox, forcing the output shaft to move downward along the axis to its limit position, completing the axial limit required for the assembly process. At this time, the retaining ring groove 16 on the output shaft is pulled down to a fixed height and accurately positioned on a reference surface at the same height as the plane where the rear accessory 5 and the retaining ring clamp 6 are located, establishing a geometric reference for the subsequent horizontal pressing.

[0033] Subsequently, the operator presses the foot pedal valve or start button to trigger the reversing valve of the pneumatic control system. The cylinder 9, mounted on the top bracket 8 of the base plate 2, inflates and begins operation. The push rod of cylinder 9 extends, and the thrust is transmitted through the second connector 10 fixed to its output end to the first connector 7, which is floatingly inserted via a U-shaped groove. A retaining clamp 6 is fixedly connected to the bottom of the first connector 7, and an accessory 5 is fixedly connected to its outer side, forming a rigid force transmission unit that moves forward. At this time, the slider at the bottom of the retaining clamp 6 slides forward along the linear slide rail 4 on the base plate 2. Because the slide rail 4 constrains all degrees of freedom except the forward direction, the sliding direction of the slider is strictly perpendicular to the output shaft axis of product 12.

[0034] As the device moves forward, the retaining ring 11, located in the C-shaped locking position at the front end of the retaining ring clamp 6, moves toward the product 12. Along this path, the rear outer edge of the retaining ring 11 abuts against the inner wall of the accessory 5. As the cylinder 9 pushes the accessory 5 forward, the open end of the retaining ring contacts the outer cylindrical surface of the output shaft of the product 12. The accessory 5 provides a continuous forward thrust through the abutting surface, and the retaining ring undergoes elastic deformation under the interaction of the thrust and the shaft resistance, gradually opening. When the retaining ring passes the maximum diameter portion of the shaft and aligns with the retaining ring groove 16, because the diameter of the retaining ring groove 16 is smaller than the outer diameter of the output shaft, the elasticity of the material itself causes it to instantly return to its initial deformation, the opening contracts, and it is pushed into the retaining ring groove 16 and locked in place. By using the fixed guide of slide rail 4 to move horizontally, the traditional manual opening and pressing method in which the operator relies on the wrist to grasp the angle in the air is replaced. This avoids assembly skewing caused by human force deviation and plastic scrap caused by uneven force on the buckle, thus reducing rework and waiting time between processes.

[0035] After the pressing action is completed, the control circuit commands cylinder 9 to intake air in the reverse direction. The push rod of cylinder 9 retracts, pulling the second connector 10 back, which in turn drives the retaining clamp 6 and accessory 5 to retract along the slide rail 4 via the first connector 7. During the timing coordination of the material handling stage, the bottom of the retaining clamp 6 slides and passes through the area below the material channel 3, and the bottom opening of the storage tank intersects the horizontal movement trajectory of accessory 5 in space. When cylinder 9 retracts, and the C-shaped locking position of accessory 5 and retaining clamp 6 retracts to the specific receiving position below the material channel 3, the space above the C-shaped locking position is freed up. At this time, the bottommost retaining ring 11 stacked inside the material channel 3 loses its support and falls into the locking position in front of retaining clamp 6 by its own weight.

[0036] To ensure stability during the material feeding process, a magnet located inside the base of the material channel 3 and directly below the receiving point provides additional downward attraction, allowing the lighter buckle to be quickly pulled downwards and adhered to the sliding surface the moment it leaves the material channel 3. This prevents it from flipping or getting stuck due to interference from surrounding airflow or friction during the descent. The retraction action of the cylinder 9 is integrated with the material feeding and picking action within a single timeframe, eliminating the need for a separate external feeding robot or material distribution cylinder 9, thus reducing the number of moving parts in the equipment. Finally, the operator simply pulls the product 12 with the buckle assembled vertically upwards from the motor base 13. At this point, the equipment is in standby mode, with the buckle clamp 6, having completed feeding, remaining below the material channel 3, awaiting the assembly of the next product 12. The entire transmission and pressing process is smooth and continuous.
