[0002] During the installation of the gearbox housing, several bearings and locating pins need to be press-fitted onto the gearbox housing. However, the existing gearbox housing press-fitting process is complex and requires multiple press-fitting machines according to the installation sequence. In addition, multiple operators are needed to move the gearbox housing through a handling mechanism during the press-fitting process, and a flipping mechanism is needed to assist in flipping the gearbox housing to press-fit the front and back of the gearbox housing separately. The existing gearbox housing press-fitting process requires multiple press-fitting machines, which increases production costs and requires a large amount of manual labor for handling and flipping operations. The press-fitting process is too complex, reduces production efficiency, and has excessively high labor costs. Summary of the Invention

[0006] In the aforementioned novel multi-composite pressing device, the pressing seat lifting drive mechanism includes a pressing seat bottom cylinder mounted on the lower end of the pressing seat via a pressing seat drive frame. The telescopic shaft of the pressing seat bottom cylinder is connected to several pressing seat lifting rods that vertically penetrate the pressing seat. The upper ends of the pressing seat lifting rods are connected to the outer periphery of the movable pressing seat. The telescopic shaft enables the pressing seat lifting rods to drive the movable pressing seat to rise and fall, facilitating the pressing of the gearbox housing on both sides and improving the pressing efficiency of the gearbox housing.

[0007] In the aforementioned novel multi-composite pressing device, the anti-collision assembly includes two anti-collision sliders respectively disposed on both sides of the pressing base along the length direction.

The track seat is provided with a notch for the blocking block to pass through, and the blocking block can move into the conveying channel under the action of the blocking cylinder. The gearbox housing is slidably disposed in the conveying channel.

[0012] In the aforementioned novel multi-composite pressing device, the pressing mechanism includes a pressing mounting base disposed on one side of the upper end of the pressing frame. A pressing cylinder is provided at the upper end of the pressing mounting base, and an upper central bearing pressing head and two side bearing pressing heads are provided at the lower end of the pressing mounting base, corresponding to the pressing hole of the lower central bearing. Both the upper central bearing pressing head and the side bearing pressing heads are controlled and connected to the pressing cylinder. The side bearing pressing heads are elastic pressing heads.

The outer side of the press-fitting sleeve will be deformed by pressure under hydraulic control, and the deformed press-fitting sleeve can clamp the intermediate shaft. The clamped intermediate shaft and the two auxiliary pressure heads can be regarded as a whole, which can act as the base for reverse press-fitting, which can facilitate the reverse press-fitting of the gearbox housing and ensure the reverse press-fitting effect of the gearbox housing.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 , Figure 6 , Figure 7As shown, this novel multi-composite pressing device includes a pressing frame 1, on which a pressing mechanism 2 is provided. The pressing mechanism 2 can press the gearbox housing. The pressing frame 1 has a pressing base 11 located at the lower end of the pressing mechanism 2. A movable pressing seat 12, which can be raised and lowered, is movably mounted on the pressing base 11. The gearbox housing is mounted on the movable pressing seat 12. The movable pressing seat 12 is connected to a pressing seat lifting drive mechanism 3. The pressing seat lifting drive mechanism 3 can drive the movable pressing seat 12 to rise and fall, thereby driving the gearbox housing to rise and fall. The pressing base 11 has sliding rails 4 that can be raised and lowered and are located on both sides of the movable pressing seat 12. The sliding rails 4 facilitate the sliding mounting of the gearbox housing on the upper end of the movable pressing seat 12. The sliding rail 4 is connected to a rail lifting drive mechanism 5, which allows the sliding rail 4 to be raised and lowered. This enables the gearbox housing to be placed on the movable pressing base 12, facilitating the pressing mechanism 2 to directly press the gearbox housing, thus improving pressing efficiency. The pressing base 11 is movably equipped with a backing component 6, which facilitates the front pressing of the gearbox housing, further improving pressing efficiency. The backing component 6 is connected to a backing drive mechanism 7, which drives the backing component 6 to slide horizontally along the pressing base 11 to the lower end of the movable pressing base 12. The backing drive mechanism 7 can move the backing component 6, adjusting its position according to the pressing process to ensure pressing efficiency.

[0031] Specifically, the movable press-fit seat 12 is movably positioned in the middle of the press-fit base 11, and the movable press-fit seat 12 is provided with a lower center bearing press-fit hole 121, in which a lower center bearing is installed. The press-fit base 11 is provided with two side shaft pin press-fit holes 111 located on both sides of the movable press-fit seat 12, and two side shaft pins are installed in the side shaft pin press-fit holes 111 on both sides. The press-fit mechanism 2 can press the side shaft pins and the lower center bearing on both sides onto the gearbox housing.

[0032] The pressing seat lifting drive mechanism 3 includes a pressing seat bottom cylinder 32 mounted on the lower end of the pressing seat 11 via a pressing seat drive frame 31. The pressing seat bottom cylinder 32 can be easily installed via the pressing seat drive frame 31. The telescopic shaft 321 of the pressing seat bottom cylinder 32 is connected to several pressing seat lifting rods 33 that vertically penetrate the pressing seat 11. The upper ends of the pressing seat lifting rods 33 are connected to the outer periphery of the movable pressing seat 12. The telescopic shaft 321 enables the pressing seat lifting rods 33 to drive the movable pressing seat 12 to lift and lower, which facilitates pressing the gearbox housing on both sides and improves the pressing efficiency of the gearbox housing.

[0033] like Figure 3 , Figure 5 , Figure 6, Figure 7 As shown, the anti-collision assembly 6 includes two anti-collision sliders 61 respectively disposed on both sides of the pressing base 11 along the length direction. The pressing base 11 is provided with two anti-collision slide rails 62 respectively horizontally disposed and inclinedly extending to the lower end of the movable pressing base 12. One end of the anti-collision slide rails 62 extends to the lower end of the movable pressing base 12. The anti-collision slide rails 62 are respectively offset on both sides of the pressing base 11 along the length direction and are parallel to each other. The anti-collision sliders 61 are respectively slidably mounted on the anti-collision slide rails 62 and thus slide to the lower end of the movable pressing base 12 under the action of the anti-collision drive mechanism 7, so that the anti-collision sliders 61 abut against the lower end of the movable pressing base 12, which facilitates the pressing mechanism 2 to press the gearbox housing and improves the pressing efficiency.

[0034] Furthermore, the reverse-adjustment drive mechanism 7 includes reverse-adjustment cylinder seats 71 respectively disposed on both sides of the press base 11 along the length direction, and reverse-adjustment drive cylinders 72 are provided on the reverse-adjustment cylinder seats 71. The telescopic rods of the reverse-adjustment drive cylinders 72 are respectively connected to the reverse-adjustment sliders 61, and the telescopic rods can drive the reverse-adjustment sliders 61 to slide on the reverse-adjustment slide rails 62, thereby improving the sliding efficiency of the reverse-adjustment sliders 61 and ensuring the press-fitting effect.

[0035] The sliding track 4 includes two track seats 41 that are movably disposed on both sides of the press base 11 along the width direction. One side of the track seats 41 is provided with a rolling element mounting seat 42 that extends axially along the track seat 41. The track seats 41 can support the rolling element mounting seat 42. Several rolling elements 43 are arranged axially in sequence on the rolling element mounting seat 42. The rolling elements 43 can make the gearbox housing slide on the track mounting seat 42. A conveying channel 44 is formed between the rolling element mounting seats 42 on the two track seats 41. The gearbox housing is slidably disposed in the conveying channel 44.

[0036] Combination Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the track lifting drive mechanism 5 includes track lifting rods 51 respectively disposed on the lower sides of both ends of the track seat 41 and vertically passing through the pressing base 11. The track lifting rods 51 enable the track seat 41 to be lifted and lowered, facilitating the pressing mechanism 2 to press the gearbox housing. The lower ends of the track lifting rods 51 extend to the bottom of the pressing base 11, and the lower ends of the track lifting rods 51 at the same end of the two track seats 41 are connected to both ends of a connecting frame 52 to ensure the lifting stability and lifting effect of the track lifting rods 51. A vertically arranged track cylinder 53 is provided below the pressing base 11, and the telescopic rod at the lower end of the track cylinder 53 is connected to the middle of the connecting frame 52. The track cylinder 53 is connected to the middle of the connecting frame 52 through the telescopic rod, which can reduce production costs while ensuring the lifting effect of the track seat 41 and facilitate installation.

[0037] The pressing frame 1 is equipped with a blocking cylinder 13. The telescopic rod of the blocking cylinder 13 is connected to a blocking block 14 located outside one of the track seats 41. The blocking cylinder 13 can control the blocking block 14. The track seat 41 is provided with a notch 15 for the blocking block 14 to pass through. The blocking block 14 can move into the conveying channel 44 under the action of the blocking cylinder 13. The blocking cylinder 13 can make the blocking block 14 block and limit the gearbox housing sliding in the conveying channel 44, so that the gearbox housing is kept on the upper end of the movable pressing seat 12, ensuring the pressing effect and improving the pressing efficiency.

[0038] Specifically, the pressing mechanism 2 includes a pressing mounting seat 21 located on one side of the upper end of the pressing frame 1. A pressing cylinder 22 is provided at the upper end of the pressing mounting seat 21, and an upper center bearing pressing head 23 corresponding to the lower center bearing pressing hole 121 and two side bearing pressing heads 24 are provided at the lower end of the pressing mounting seat 21. The upper center bearing pressing head 23 and the side bearing pressing heads 24 are all connected to the pressing cylinder 22 for control. The pressing cylinder 22 can initiate the lifting and lowering action of the pressing mounting seat 21 and can control the upper center bearing pressing head 23 and the side bearing pressing heads 24 to press the gearbox housing. The pressure head 24 is an elastic pressure head. The upper central bearing pressure head 23 contains a liftable intermediate shaft 231, and a pressure-increasing sleeve 232 is provided around the circumference of the intermediate shaft 231. The pressure-increasing sleeve 232 is connected to the pressing cylinder 22. After the intermediate shaft 231 is pressed for the first time, it will experience a certain degree of lifting. At this time, pressure is applied to the outside of the pressure-increasing sleeve 232 under hydraulic control, causing the pressure-increasing sleeve 232 to deform. The deformed pressure-increasing sleeve 232 clamps the intermediate shaft 231, generating static friction. The magnitude of the static friction can be adjusted by regulating the hydraulic pressure. This, combined with the side bearing pressure heads 24 on both sides... 4. The spring force at this position allows the intermediate shaft 231 and the two auxiliary pressure heads 24 to be considered as a whole, acting as a base for reverse pressing. This facilitates the reverse pressing of the gearbox housing, ensures the effectiveness of the reverse pressing, and improves pressing efficiency. Furthermore, the lower end of the pressing mounting base 21 is equipped with two positioning pins 211, which are vertically inserted into the pressing mounting base 21 and connected to the positioning cylinder 212 located at the upper end of the pressing mounting base 21. The positioning cylinder 212 positions the positioning pins 211 on the gearbox housing, ensuring the pressing effect. The assembly mechanism 2 is also equipped with a pressing alarm component. The pressing alarm component has a preset pressing descent height setting, and if the height deviation after pressing exceeds the preset range during the pressing process, it can control the equipment to pause, protecting the equipment and personnel safety and triggering an alarm. The pressing alarm component also has a pressure detection program. When the bearing and pin being pressed are misaligned, or when there is a foreign object at the pressing point, the pressing alarm component will automatically stop the equipment. The dual warning of height warning and pressure detection program can greatly ensure the safety of the equipment and operators, and ensure the accuracy of pressing.

[0039] Combination Figure 1 , Figure 2As shown, the pressing frame 1 has a protective cover slide rail seat 16 on each side. Each protective cover slide rail seat 16 has a vertically arranged protective cover slide rail 161. Several protective cover sliding connecting blocks 162 are slidably mounted on the protective cover slide rail 161. A protective cover limiting part 163 is provided at the lower end of the protective cover slide rail 161. The protective cover limiting part 163 can limit the movement of the protective cover sliding connecting blocks 162. One side of the protective cover sliding connecting block 162 is fixedly connected to the pressing protective frame 17. When the protective cover sliding connecting block 162 slides, it can drive the pressing protective frame 17 to slide. The protective cover sliding connecting block 162 is located near... A protective cover lifting cylinder 164 is provided on one side of the protective cover slide rail seat 16. The protective cover lifting cylinder 164 is connected to the protective cover sliding connecting block 162 via the protective cover slide rail telescopic rod 165. The protective cover sliding connecting block 162 is slidably mounted on the protective cover slide rail 161 via the protective cover lifting cylinder 164. When the gearbox housing needs to be press-fitted, the press-fitting protective frame 17 descends. When the gearbox housing press-fitting is completed, the press-fitting protective frame 17 rises. The press-fitting protective frame 17 is movably mounted on the outer side of the press-fitting base 11. The size of the press-fitting protective frame 17 is larger than the size of the press-fitting base 11, which can ensure the protective effect of the press-fitting protective frame 17.

[0040] The principle of this embodiment is as follows: the gearbox housing is placed on the sliding rail 4 and slides within the conveying channel 44. The gearbox housing is limited by the blocking block 14, ensuring that the gearbox housing is stably positioned on the upper end of the movable pressing seat 12. At the same time, the pressing protective frame 17 slides down through the protective cover slide rail seat 16, and the positioning post 211 is positioned downward on the gearbox housing through the positioning cylinder 212. The blocking block 14 retracts through the blocking cylinder 13. Then, the pressing lifting drive mechanism 3 drives the movable pressing seat 12 and the gearbox housing to rise. The anti-collision component 6 is slidably positioned by the anti-collision drive mechanism 7. The lower end of the movable pressing seat 12 abuts against the movable pressing seat 12, and the sliding rails 4 on both sides are lowered by the rail lifting drive mechanism 5 to ensure the normal operation of the pressing. The pressing cylinder 22 drives the upper center bearing pressing head 23 and the side bearing pressing head 24 to press the gearbox housing. The upper center bearing pressing head 23 and the side bearing pressing head 24 are equipped with bearings. The pressing cylinder 22 presses the bearing of the side bearing pressing head 24 completely in. After the upper center bearing pressing head 23 pushes back a certain distance, the pressure sleeve 232 locks the intermediate shaft 231, which can make the side bearing pressing head 24 and the upper center bearing... The pressure head 23 presses against the gearbox housing simultaneously, ensuring uniform force on the gearbox housing and guaranteeing the pressing effect. After the front pressing of the gearbox housing is completed, the pressing cylinder 22 rises and the backing component 6 retracts via the backing drive mechanism 7. The movable pressing seat 12 descends a certain distance via the pressing lifting drive mechanism 3 and is then locked by an air lock. At this time, the intermediate shaft 231 has been locked by the pressure sleeve 232, and the intermediate shaft 231 and the two auxiliary pressure heads 24 are considered as a whole, acting as the base for the reverse pressing. The pressing cylinder 22 presses downwards, which can press the bearing in the lower center bearing pressing hole 121. Pressing the shaft pin in the side shaft pin press hole 111 can save the time of flipping and transporting the gearbox housing, improve installation efficiency, and reduce production costs. When the reverse side of the gearbox housing is press-fitted, the positioning column 211 rises through the positioning cylinder 212, and the pressing cylinder 22 drives the upper center bearing press head 23 and the side bearing press head 24 to rise, and the pressing protective frame 17 rises synchronously. When the rise is about to end, the hydraulic pressure on the outside of the pressure sleeve 232 is released, and the intermediate shaft 231 returns to the initial height under the action of the spring at the end of the intermediate shaft 231. The sliding rail 4 rises and returns to its position through the rail lifting drive mechanism 5.
