Description

Technical Field

[0001] The present invention belongs to the technical field of automotive component assembly equipment and relates to a transmission shaft pipe press. Background Art

[0002] The transmission shaft is an important automotive component. It is a transmission component of the transmission and needs to undergo processes such as press-fitting and airtight detection during the production and assembly process.

[0003] The patent with the application publication number CN112296651A discloses an automatic assembly mechanism for a one-way clutch slip ring and a snap ring, including a frame. The frame is provided with an indexing turntable device. The indexing turntable device is sequentially provided with a conveying device, a slip ring assembly device, a snap ring loading device, and a snap ring press-fitting device in a clockwise direction. An output device is arranged on the other side of the frame relative to the conveying device. The indexing turntable device includes a turntable assembly, an indexing assembly, and a rotary cylinder for driving the rotation of the turntable assembly. The turntable assembly is respectively provided with a first station, a second station, a third station, and a fourth station. The turntable assembly includes an outer turntable, an inner fixed disk, a plurality of product molds, and a plurality of positioning molds. The product molds and the positioning molds are arranged at intervals. The inner fixed disk is respectively provided with station sensors corresponding to the first station, the second station, the third station, and the fourth station. The indexing assembly can grab the positioning molds and fit them into the product molds.

[0004] The above device can achieve the press-fitting of the snap ring, but the placement and press-fitting of the snap ring are respectively placed at different stations, and when press-fitting, the workpiece directly bears the downward pressure of the pressing column, and the snap ring may shift or even cause damage to the workpiece, making it difficult to ensure the press-fitting effect. For this reason, those of ordinary skill in the art are more likely to consider: 1. Design a structure on the workpiece that can be initially positioned with the snap ring to reduce the shift of the snap ring during the transfer process; 2. Directly perform the press-fitting operation after the snap ring is placed on the workpiece. Summary of the Invention

[0005] In view of the above problems existing in the prior art, the present invention provides a transmission shaft pipe press. The technical problem to be solved by the present invention is: to ensure the press-fitting effect of the snap ring.

[0006] The object of the present invention can be achieved by the following technical solutions:

[0007] A gearbox rotating shaft pressing tube machine, comprising a workbench and a rotating conveying part rotatably arranged on the workbench. The rotating conveying part is provided with a plurality of positioning seats capable of circumferentially positioning with the gearbox rotating shaft. A support frame is fixedly arranged on the workbench. A horizontally arranged support plate and a pressing column capable of moving up and down are connected to the support frame. It is characterized in that the support plate is located below the pressing column. The support plate is provided with a fixed part through hole vertically facing the pressing column and allowing the pressing column to pass through. The positioning seat can move to directly below the fixed part through hole. The workbench is further connected with a clamping part capable of moving up and down. The clamping part is located directly below the positioning seat and is vertically aligned with the position of the fixed part through hole. The clamping part can move upward and clamp the gearbox rotating shaft between the support plate and the clamping part.

[0008] The rotating conveying part can drive the gearbox rotating shaft component to pass through different stations in sequence through the self-rotation action relative to the workbench, realizing assembly line processing and occupying a small space. The positioning seat can circumferentially position with the gearbox rotating shaft. Specifically speaking, the positioning seat is provided with a structure that can position with the outer peripheral key groove of the gearbox rotating shaft. In this way, it can be ensured that the oil holes on the outer periphery of the gearbox rotating shaft can maintain a fixed angle and position after being placed on the positioning seat, so as to facilitate processes such as airtight detection. The pressing column arranged on the support frame can move downward to press the snap ring into the end hole of the gearbox rotating shaft to form a stop; by arranging a support plate below the pressing column and opening a fixed part through hole on the support plate, the snap ring can be placed in the fixed part through hole through the existing conveying structure before pressing. When the pressing column moves downward, the snap ring inside it is driven and pressed into the gearbox rotating shaft. The snap ring is placed and integrated at the pressing station, and there is no need for the gearbox rotating shaft to position the snap ring, reducing the position change during the movement of the snap ring, which is beneficial to ensuring accurate pressing. At the same time, the clamping part on the workbench can rise to cooperate with the lower surface of the support plate to vertically clamp the gearbox rotating shaft. In this way, when the gearbox rotating shaft is clamped and lifted, it can abut against the lower surface of the support plate, thereby eliminating the reserved movement space between the two, that is, the fixed part through hole is seamlessly docked with the gearbox rotating shaft, so that the pressing spring coming out of the fixed part through hole will not have horizontal movement, ensuring that the snap ring is accurately and smoothly clamped into the gearbox rotating shaft. After the pressing is completed, the clamping part falls back. After the clamping is released, the gearbox rotating shaft can accurately fall back to the positioning seat for positioning, realizing accurate operation and ensuring the pressing effect of the snap ring.

[0009] In the above-mentioned gearbox rotating shaft pressing tube machine, the inner wall of the upper end of the fixed part through hole has a tapered guiding step surface that narrows from top to bottom. This is beneficial to making the snap ring support on the guiding step surface after being placed in the fixed part through hole. When the pressing column presses down, it drives the snap ring to contract and pre-tighten along the guiding step surface. That is, its pre-tightened size can be adapted to the end hole of the gearbox rotating shaft, so that the snap ring can enter the gearbox rotating shaft more smoothly when leaving the fixed part through hole and will not act on the end face of the gearbox rotating shaft, which can reduce the damage to the end of the gearbox rotating shaft.

[0010] In the above-mentioned gearbox rotating shaft pipe press, a locking part is connected to the support frame and can extend horizontally towards the side where the rotating conveying part is located. The locking part has a positioning post, and the positioning seat or the rotating conveying part has a positioning jack. When the locking part extends, the positioning post can be horizontally inserted into the positioning jack. In this way, when the positioning seat moves to below the support plate, the locking part extends and the position of the rotating conveying part at this place is locked through the cooperation of the positioning post and the positioning jack, thereby making the position of the positioning seat more accurate and stable. In this way, when the press-fitting is completed and the gearbox rotating shaft falls back, it can more accurately fall into the positioning seat to form circumferential positioning.

[0011] In the above-mentioned gearbox rotating shaft pipe press, a feeding track for conveying snap rings is further provided on the workbench. A feeding plate is connected to the support plate. The side of the feeding plate has a notch groove for positioning and accommodating the snap ring. The discharging end of the feeding track is arranged close to the side of the feeding plate and is directly opposite and communicated with the notch groove. The feeding plate can drive the snap ring in the notch groove to slide along the upper surface of the support plate and make the notch groove vertically directly opposite and communicated with the fixing part through hole. In this way, the feeding track can send the snap ring into the notch groove, and the feeding plate drives the snap rings in the notch groove to move to the fixing part through hole one by one. Under the action of gravity, the snap ring can fall into the fixing part through hole to wait for press-fitting. Subsequently, the feeding plate retracts to enable the next snap ring to enter the notch groove from the feeding track, realizing the stable and accurate conveying of the snap ring to the fixing part through hole.

[0012] In the above-mentioned gearbox rotating shaft pipe press, the inner wall of the notch groove includes a first flat section, an arc section adapted to the outer peripheral shape of the snap ring, and a second flat section that are sequentially joined. The first flat section and the second flat section are parallel to each other. The feeding plate reciprocates along the perpendicular direction of the first flat section. The length dimension of the first flat section is greater than the length dimension of the second flat section, and the first flat section is located on the side of the inner wall of the notch groove away from the rotating conveying part. The snap ring itself is annular and has an adjusting notch. In this way, the arc section is adapted to the outer peripheral arc surface of the snap ring, and the first flat section can abut against both ends of the snap ring at the adjusting notch. When the feeding plate moves, both ends of the snap ring are supported on the first flat section, which is beneficial to making the position of the snap ring in the notch groove more stable and avoiding horizontal movement, ensuring that the snap ring can accurately and smoothly fall into the fixing part through hole to achieve accurate press-fitting.

[0013] In the above-mentioned gearbox rotating shaft pipe press, a limiting plate is provided on the support plate. The limiting plate has a slot, and the feeding plate has a convex block. The feeding plate can abut against the limiting plate to make the convex block be positioned and inserted into the slot and at the same time make the notch groove vertically directly opposite and communicated with the fixing part through hole. In this way, the feeding plate can control the accurate alignment of the notch groove and the fixing part through hole through cooperation with the limiting plate, with more accurate and convenient positioning and improved press-fitting effect.

[0014] In the above-mentioned gearbox rotating shaft pipe press, a limiting stop strip is fixedly arranged on the upper surface of the support plate. The limiting stop strip is perpendicular to the first flat section along the length direction, and the limiting stop strip is arranged close to the side of the feeding plate where the notch groove is located. The two ends of the limiting stop strip are respectively opposite to the position of the notch groove and the position of the fixing part through hole. In this way, the limiting stop strip can form a certain blockage of the opening of the notch groove when the feeding plate conveys the circlip, avoiding the circlip from slipping out of the notch groove during the transfer process and ensuring stable press-fitting.

[0015] In the above-mentioned gearbox rotating shaft pipe press, a pressing block fixedly embedded in the notch groove is arranged on the feeding plate. The bottom surface of the pressing block is spaced from the support plate and only allows a single circlip to pass through. In this way, the pressing block can limit the vertical moving space of the circlip in the notch groove, so that the circlip can still maintain a stable flat state when it falls into the fixing part through hole, realizing precise press-fitting.

[0016] In the above-mentioned gearbox rotating shaft pipe press, both the support plate and the pressing block are provided with vertically arranged detection through holes. The two detection through holes are coaxially arranged and are both opposite to the position of the arc section. A distance sensor is fixedly arranged on the support frame along the vertical direction at a set distance from the detection through holes. In this way, when the circlip is accurately positioned in the notch groove, the circlip itself will block the light passing through the two detection through holes. In this way, by using an existing distance sensor through the detection through holes, it can be judged whether the circlip is fully positioned in the notch groove, and thus provide a basis for controlling the feeding action of the feeding plate.

[0017] In the above-mentioned gearbox rotating shaft pipe press, a positioning plate is arranged on the rotating conveying part. The positioning plate is located directly below the positioning seat, and the positioning plate is provided with a positioning hole for the lower end of the gearbox rotating shaft to be inserted for positioning. The clamping part is always located below the positioning plate. In this way, the positioning hole can provide horizontal positioning for the lower end of the longer gearbox rotating shaft. Its cooperation with the positioning seat can ensure sufficient position stability of the gearbox rotating shaft. After the clamping part rises, the positioning hole of the positioning plate still forms a constraint and guidance for the lower end of the gearbox rotating shaft, which is beneficial to the accurate positioning of the gearbox rotating shaft.

[0018] Compared with the prior art, the advantages of the present invention are as follows:

[0019] Before press-fitting, the present gearbox rotating shaft pipe press can place the circlip into the fixing part through hole through the existing conveying structure. When the pressing column moves down, the circlip inside it is driven and pressed into the gearbox rotating shaft. The placement of the circlip is integrated at the press-fitting station, and there is no need for the gearbox rotating shaft to position the circlip, reducing the position change of the circlip during the moving process, which is beneficial to ensuring precise press-fitting. At the same time, when the gearbox rotating shaft is clamped and lifted, it can abut against the lower surface of the support plate, thereby eliminating the reserved moving space between the two, that is, the seamless docking of the fixing part through hole and the gearbox rotating shaft, so that the pressed spring coming out of the fixing part through hole will not have horizontal movement, and the circlip is accurately and smoothly clamped into the gearbox rotating shaft, ensuring the press-fitting effect of the circlip.

[0039] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0040] Such as Figure 1-10As shown in the figure, the transmission shaft pressing machine of the present invention includes a workbench 1 and a rotating conveying part 2 rotatably arranged on the workbench 1. There are six positioning seats 3 on the rotating conveying part 2 that can be circumferentially positioned with the transmission shaft of the gearbox. A support frame 4 is fixedly arranged outside the rotating conveying part on the workbench 1. A horizontally arranged support plate 5 and a pressing column 41 that can be driven to move up and down by a cylinder are connected to the support frame 4. The support plate 5 is located below the pressing column 41. There is a fixed part through hole 51 on the support plate 5 that is vertically aligned with the pressing column 41 and allows the pressing column 41 to pass through. The positioning seat 3 can rotate to directly below the fixed part through hole 51. A clamping part 6 that can move up and down is also connected to the workbench 1. The clamping part 6 is located directly below the positioning seat 3 and is vertically aligned with the position of the fixed part through hole 51. The clamping part 6 can move upward and clamp the transmission shaft of the gearbox between the support plate 5 and the clamping part 6. The rotating conveying part 2 can drive the transmission shaft component of the gearbox to pass through different stations in sequence through its self-rotation relative to the workbench 1, realizing assembly line processing and occupying less space. The positioning seat 3 can be circumferentially positioned with the transmission shaft of the gearbox. Specifically, there is a structure in the groove on the positioning seat 3 that can be positioned with the outer peripheral key groove of the transmission shaft. In this way, it can be ensured that the oil holes on the outer periphery of the transmission shaft maintain a fixed angle and position after being placed on the positioning seat 3, facilitating processes such as airtight detection. The pressing column 41 arranged on the support frame 4 can move downward to press the snap ring into the end hole of the transmission shaft to form a stop; by arranging the support plate 5 below the pressing column 41 and opening the fixed part through hole 51 on the support plate 5, the snap ring can be placed in the fixed part through hole 51 through the existing conveying structure before pressing. When the pressing column 41 moves downward, the snap ring inside it is driven and pressed into the transmission shaft. The snap ring is placed and integrated at the pressing station, and there is no need for the transmission shaft to position the snap ring, reducing the position change during the movement of the snap ring, which is beneficial to ensuring accurate pressing. At the same time, the clamping part 6 on the workbench 1 can rise to cooperate with the lower surface of the support plate 5 to vertically clamp the transmission shaft. In this way, when the transmission shaft is clamped and lifted, it can abut against the lower surface of the support plate 5, thereby eliminating the reserved movement gap between the two, that is, the fixed part through hole 51 is seamlessly docked with the transmission shaft, so that the pressing spring coming out of the fixed part through hole 51 will not move horizontally, ensuring that the snap ring is accurately and smoothly clamped into the transmission shaft. After pressing is completed, the clamping part 6 falls back. After releasing the clamping, the transmission shaft can accurately fall back onto the positioning seat 3 for positioning, realizing accurate operation and ensuring the pressing effect of the snap ring. Specifically, the inner wall of the upper end of the fixed part through hole 51 has a guiding step surface 511 that tapers downward. This is beneficial for the snap ring to be supported on the guiding step surface 511 after being placed in the fixed part through hole 51. When the pressing column 41 presses downward, it drives the snap ring to contract and pre-tighten along the guiding step surface 511. That is, its pre-tightened size can be adapted to the end hole of the transmission shaft, so that when the snap ring leaves the fixed part through hole 51 and enters the transmission shaft, it can be more smooth and will not act on the end face of the transmission shaft, reducing damage to the end of the transmission shaft.Specifically, a feeding track 43 for conveying snap rings is further provided on the workbench 1. The feeding track 43 can be an existing component, and feeding is achieved through vibration. A feeding plate 7 is connected to the support plate 5. The side of the feeding plate 7 is straight and has a notch groove 71 for positioning and accommodating the snap ring. The discharging end of the feeding track 43 is arranged close to the side of the feeding plate 7 and is directly opposite and communicated with the notch groove 71. The feeding plate 7 can drive the snap ring in the notch groove 71 to slide along the upper surface of the support plate 5 and make the notch groove 71 vertically opposite and communicated with the fixing part through hole 51. In this way, the feeding track 43 can send the snap ring into the notch groove 71, and the feeding plate 7 drives the snap ring in the notch groove 71 to move to the fixing part through hole 51 one by one. Under the action of gravity, the snap ring can fall into the fixing part through hole 51 to wait for press-fitting. Subsequently, the feeding plate 7 retracts to enable the next snap ring to enter the notch groove 71 from the feeding track 43, realizing the stable and precise conveyance of the snap ring to the fixing part through hole 51. Preferably, the inner wall of the notch groove 71 includes a first flat section 711, an arc section 712 that can be adapted to the outer peripheral shape of the snap ring, and a second flat section 713 that are sequentially joined. The first flat section 711 and the second flat section 713 are parallel to each other. The feeding plate 7 reciprocates along the perpendicular direction of the first flat section 711. The length dimension of the first flat section 711 is greater than the length dimension of the second flat section 713. The first flat section 711 is located on the side of the inner wall of the notch groove 71 away from the rotary conveying part 2. The snap ring itself is annular and has an adjustment notch. In this way, the arc section 712 is adapted to the outer peripheral arc surface of the snap ring, and the first flat section 711 can abut against both ends of the snap ring at the adjustment notch. When the feeding plate 7 moves, both ends of the snap ring are supported on the first flat section 711, which is beneficial to making the position of the snap ring in the notch groove 71 more stable and avoiding horizontal displacement, ensuring that the snap ring can accurately and smoothly fall into the fixing part through hole 51 and realizing precise press-fitting.

[0041] Such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 9As shown, a locking portion 42 that can extend horizontally toward the side where the rotary conveying portion 2 is located is connected to the support frame 4. The locking portion 42 has two horizontally spaced positioning posts 421. On the rotary conveying portion 2 below the positioning seat 3, there are two positioning sockets 21. When the locking portion 42 extends, the positioning posts 421 can be horizontally inserted into the positioning sockets 21. In this way, when the positioning seat 3 moves below the support plate 5, the locking portion 42 extends and cooperates with the positioning posts 421 and the positioning sockets 21 to lock the position of the rotary conveying portion 2 at this place, thereby making the position of the positioning seat 3 more accurate and stable. In this way, when the pressing is completed, when the transmission shaft of the gearbox falls back, it can more accurately fall into the positioning seat 3 to form circumferential positioning. A positioning plate 9 is provided on the rotary conveying portion 2. The positioning plate 9 is located directly below the positioning seat 3. The positioning plate 9 has a positioning hole 91 for the lower end of the transmission shaft of the gearbox to be positioned and inserted. The clamping portion 6 is always located below the positioning plate 9. In this way, the positioning hole 91 can provide horizontal positioning for the longer lower end of the transmission shaft of the gearbox. Its cooperation with the positioning seat 3 can ensure sufficient position stability of the transmission shaft of the gearbox. After the clamping portion 6 rises, the positioning hole 91 of the positioning plate 9 still forms a constraint and a guide for the lower end of the transmission shaft of the gearbox, which is beneficial to the accurate positioning of the transmission shaft of the gearbox.

[0042] As Figure 2-10As shown in the figure, the support plate 5 is provided with a limit plate 52, the limit plate 52 is provided with a slot 521, the feeding plate 7 is provided with a bump 72, and the feeding plate 7 can abut against the limit plate 52 so that the bump 72 is positioned and inserted into the slot 521, and at the same time, the notch groove 71 is vertically aligned and communicated with the fixing part through hole 51. In this way, the feeding plate 7 can be controlled to accurately align the notch groove 71 with the fixing part through hole 51 by cooperating with the limit plate 52, the positioning is more accurate and convenient, and the pressing effect is improved. A limit stop bar 53 is fixedly arranged on the upper surface of the support plate 5, the limit stop bar 53 is perpendicular to the first flat section 711 along the length direction, the limit stop bar 53 is arranged close to the side of the feeding plate 7 where the notch groove 71 is located, and the two ends of the limit stop bar 53 are respectively opposite to the positions of the notch groove 71 and the fixing part through hole 51. In this way, the limit stop bar 53 can form a certain blockage for the opening of the notch groove 71 when the feeding plate 7 conveys the circlip, avoiding the circlip from falling out of the notch groove 71 during the transfer process and ensuring the stability of the pressing. A pressing block 73 fixedly embedded in the notch groove 71 is arranged on the feeding plate 7, and the bottom surface of the pressing block 73 is spaced from the support plate 5 and only allows a single circlip to pass through. In this way, the pressing block 73 can limit the vertical movement space of the circlip in the notch groove 71, so that the circlip can still maintain a stable flat state when falling into the fixing part through hole 51, realizing accurate pressing. Detection through holes 8 are vertically arranged on both the support plate 5 and the pressing block 73, the two detection through holes 8 are coaxially arranged and are both opposite to the position of the arc section 712, a distance sensor 44 is fixedly arranged on the support frame 4 along the vertical direction and is arranged at a distance from the detection through hole 8, and a distance sensor 44 vertically arranged is also fixedly arranged at the bottom of the support plate 5 and is coaxially arranged with the detection through hole 8. In this way, when the circlip is accurately positioned in the notch groove 71, the circlip itself will block the light passing through the two detection through holes 8. In this way, by using the existing distance sensor 44 through the detection through hole 8, it can be judged whether the circlip is fully positioned in the notch groove 71, and further provide a basis for the control of the feeding action of the feeding plate 7.

[0043] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
