For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0040] Please refer to Figures 1-6 The present application provides a technical scheme:

[0041] For example, Figures 1-3As shown, the deep groove ball bearing combined ball assembling device provided by the utility model, including bottom plate 1 and outer ring deformation pressurizing mechanism, outer ring deformation pressurizing mechanism includes cylinder drive mechanism, lever mechanism 2, slide rail mechanism 3 and limiting mechanism 4 arranged on bottom plate 1. The area of bottom plate 1 between slide rail mechanism 3 and limiting mechanism 4 is deep groove ball bearing placement area 6, and deep groove ball bearing 14 is fixed and limited in the area and receives force, and the assembly of steel ball is completed. And the moving center of slide rail mechanism 3 and limiting mechanism 4 and the axis of deep groove ball bearing placement area 6 are located on the same axis, so that the force direction is consistent with the deformation force direction of the outer ring of deep groove ball bearing 14, and partial load or local stress concentration is avoided, and the assembly precision is improved. The working end of lever mechanism 2 is connected with the front end of slide body 302 of slide rail mechanism 3, and the cylinder drive mechanism provides the first radial thrust for slide rail mechanism 3 through lever mechanism 2. Under the action of the first radial thrust of lever mechanism 2, slide rail mechanism 3 and limiting mechanism 4 pressurize the outer ring of deep groove ball bearing on deep groove ball bearing placement area 6, so that the outer ring is elastically deformed, and limiting mechanism 4 restricts the radial deformation range of the outer ring of deep groove ball bearing, so that plastic deformation is prevented, and strain ε needs to be ensured to be less than material yield limit ε y .

[0042] Lever mechanism 2 includes fixed support seat and lever arm 201, the fixed support seat is fixedly arranged on bottom plate 1, one end of lever arm 201 is hinged with fixed support seat through positioning pin 203, and lever arm 201 can rotate around the fulcrum provided by positioning pin 203; the force end and the working end of lever arm 201 are arranged on the two sides of lever arm 201 respectively, and the distance from the force end of lever arm 201 to the fulcrum is greater than the distance from the working end of lever arm 201 to the fulcrum; first push column 204 and second push column 205 are fixedly connected with the working end and the force end of lever arm 201 respectively, the piston rod of cylinder 5 of cylinder drive mechanism is connected with second push column 205 of lever arm 201, and the front end of slide body 302 of slide rail mechanism 3 is connected with first push column 204.

[0043] Positioning pin 203 is the fulcrum of lever mechanism 2 and is installed on bottom plate 1 through bolts; the end of piston rod of cylinder 5 of cylinder drive mechanism is connected with cylinder top block 7, and the piston rod of cylinder 5 is connected with second push column 205 through cylinder top block 7. In lever mechanism 2, the ratio of the input force and the output force corresponding to the force end and the working end on lever arm 201 is 1:3-5.

[0044] Cylinder 5 is a power source, specifically a pneumatic pressure control: cylinder 5 adopts a pneumatic drive type execution cylinder, and is provided with a low-pressure pneumatic execution mechanism, and the working pressure is less than or equal to 0.5 MPa.

[0045] When the output end of the piston rod of cylinder 5 extends, the piston rod will drive the cylinder top block 7 to push the second push column 205. Since the second push column 205 is fixedly connected to the force-applying end of the lever arm 201, the thrust of cylinder 5 will be transmitted through the second push column 205 to the first push rod 204 at the working end of the lever arm 201, pushing the slide rail mechanism 3 on its right side. Under the action of the first radial thrust of the lever mechanism 2, the slide rail mechanism 3 and the limiting mechanism 4 pressurize the outer ring of the deep groove ball bearing in the deep groove ball bearing placement area 6, causing it to undergo elastic deformation.

[0046] This utility model discloses a ball assembly device for deep groove ball bearings. Utilizing the controllable elastic deformation of the outer ring of the deep groove ball bearing 14, a lever mechanism 2 precisely compresses the outer ring along the axis of the bearing 14, while a limiting mechanism 4 limits and fixes the bearing 14, ensuring that the deformation of the outer ring is within a reasonable range. This elastic deformation temporarily expands the groove, allowing the steel balls to fall freely, avoiding the scratching problem caused by traditional forced pressing methods. Simultaneously, the design of amplifying the thrust of the cylinder 5 through a lever ratio achieves precise force application with low energy consumption, ensuring the bearing outer ring remains within its elastic deformation range, avoiding plastic deformation, and guaranteeing that the bearing's vibration value, rotational flexibility, and other performance characteristics are not affected, effectively improving the assembly efficiency of deep groove ball bearings.

[0047] like Figure 2 As shown, an L-shaped fixing plate 8 is vertically connected to the outer wall of the base plate 1 at the top corner of the lever arm 201 via bolts, for supporting and fixing the cylinder 5. The bottom of the first side plate of the L-shaped fixing plate 8 is fixed to one side wall of the base plate 1 via bolts.

A second through hole matching the piston rod of the cylinder 5 is provided on the first side plate above the base plate 1. The piston rod of the cylinder 5 passes through the second through hole and connects to the cylinder top block 7. This ensures that the cylinder 5 will not shake or deviate during operation, improving the stability and reliability of the device. The design of the L-shaped fixing plate 8 can also reduce the reaction impact of the cylinder 5. The bolted connection between the fixing plate 8 and the base plate 1 distributes the reaction force to various parts of the L-shaped fixing plate 8, enhancing the impact resistance of the base plate 1 in the stress area. The bottom of the first and second side plates of the L-shaped fixing plate 8 is lower than the bottom of the base plate 1, and multiple base plate support legs 11 with the same height as the L-shaped fixing plate 8 being lower than the bottom of the base plate 1 are fixedly connected to the bottom edge of the base plate 1. These legs are used to support the balance of the assembled ball-mounting device and ensure the stability of the device.

[0048] The slide rail mechanism 3 is a whole linear guide rail linear slide rail, which comprises a slide rail base 301 and a sliding body 302. The upper surface of the slide rail base 301 is inwardly recessed to be provided with a linear guide rail sliding groove matched with the sliding body 302. The sliding body 302 is embedded in the sliding groove of the slide rail base 301 and can move together with the slide rail base 301. A square mounting through slot 12 is formed in the bottom plate 1 below the slide rail mechanism 3. An installation plate 13 is installed on the lower surface of the bottom plate 1 below the bottom plate 1 and below the mounting through slot 12 and spans the mounting through slot 12. The installation plate 13 is installed on the bottom of the bottom plate 1 through bolts at the upper and lower ends thereof. The length of the installation plate 13 is greater than the width of the mounting through slot 12. The upper surface of the installation plate 13 is provided with a transverse first linear sliding groove. The bottom of the slide rail base 301 is further provided with a first direct slide rail matched with the linear sliding groove. The slide rail base 301 is installed in the mounting through slot 12. The length of the slide rail base 301 is less than the length of the mounting through slot 12. The slide rail base 301 near the first push column 204 is tightly connected with the bottom plate 1 through a return spring. The height of the bottom of the sliding body 302 is greater than that of the bottom plate 1. The length of the sliding body 302 is greater than the length of the mounting through slot 12, and the two ends of the sliding body 302 extend out of the front and rear sides of the mounting through slot 12. The width of the slide rail base 301 matches the width of the mounting through slot 12, and the two sides of the slide rail base 301 are slidably connected in the second linear sliding grooves of the second slide rails in the inner walls of the two sides of the mounting through slot 12.

[0049] The limiting mechanism 4 comprises a limiting box body 401 provided with vertical limiting side walls on the front side, a side baffle 402 and an adjusting rod 404. The limiting box body 401 is provided with two rows of transverse slot holes 403 arranged in parallel in the middle part. The limiting box body 401 is transversely movably installed on the bottom plate 1 along the central axis of the slide rail mechanism 3. The bottom plate 1 below the limiting mechanism 4 is provided with screw holes 10 matched with the structure of the transverse slot holes 403. The inner hexagonal cylindrical head screw 9 and the bottom locking nut are sequentially inserted into the transverse slot holes 403 and the corresponding screw holes 10. The outer diameter of the inner hexagonal cylindrical head screw 9 is greater than the width of the transverse slot holes 403, so as to fasten and adjust the position between the limiting box body 401 and the bottom plate 1. The limiting mechanism 4 is fixed on the bottom plate 1 through bolts, so as to further enhance the stability of the device. The multiple screw holes 10 on the bottom plate 1 are matched with the transverse slot holes 403, so that the position of the limiting mechanism 4 can be flexibly adjusted according to the actual needs, so as to adapt to the bearing assembly requirements of different specifications.

[0050] A plurality of adjusting rods 404 are arranged between the side baffle 402 and the rear side wall of the limiting box 401, one end of the adjusting rod 404 is fixedly connected with the rear side wall of the limiting box 401, the other end of the adjusting rod 404 penetrates through the rear of the side baffle 402, and the end is tightly connected through a nut. By adjusting the tightness of the adjusting nut, the position of the limiting mechanism 4 can be finely adjusted, so that the movement range of the sliding body 302 is controlled, and it is ensured that bearings of different specifications can complete assembly within the deformation control range; meanwhile, the design of the side baffle 402 and the adjusting rod 404 enhances the stability of the limiting mechanism 4, and it is ensured that high precision and high efficiency can be maintained in long-term use.

[0051] The limiting box 401 is made of tungsten-cobalt hard alloy YG8, and is internally provided with a preloaded spring and a plurality of parallel rib plates, and the preloaded spring is embedded in the interval cavity between two adjacent parallel rib plates. The limiting mechanism 4 is provided with a hard alloy limiting block and a preloaded spring, which can compensate for tolerances, limit the radial deformation range of the bearing outer ring, avoid plastic deformation, prevent local stress concentration, and ensure uniform deformation without plastic deformation. The tungsten-cobalt hard alloy has extremely high hardness and wear resistance, can withstand the pressure and friction force generated during the force application of the bearing outer ring, and avoids failure of the limiting mechanism 4 due to wear or deformation; a plurality of parallel rib plates are arranged in the limiting mechanism 4, and the rib plates enhance the rigidity of the limiting mechanism 4, can effectively limit the radial deformation range of the bearing outer ring, and ensure that the deformation amount is controlled within the elastic deformation range; the plurality of parallel rib plates can uniformly distribute the force to the entire contact surface of the limiting mechanism 4, avoid local stress concentration, and ensure uniform deformation of the bearing outer ring without plastic deformation. The spacing of the rib plates is less than or equal to 150 mm, and the inner diameter range of the deep groove ball bearing 14 is 20-120 mm.

[0052] The deep groove ball bearing combined ball assembling device of the utility model, in the specific use process:

[0053] As Figures 4-6 shown, the deep groove ball bearing 14 is placed in the deep groove ball bearing placing area 6, the position of the limiting mechanism 4 is accurately adjusted according to the actual bearing size and the size of the steel ball to be filled, and after the adjustment is completed, the deep groove ball bearing 12 is fixedly limited. The cylinder 5 serves as a power source, and outputs a pushing force to the force applying end (working end) of the lever arm 201 through the cylinder top block 7. The lever arm 201 accurately amplifies the pushing force of the cylinder 5 through the lever ratio 3-5:1, realizes accurate force application control on the outer ring of the deep groove ball bearing 14, saves time and effort, and significantly improves the processing efficiency.

[0054] When the lever arm 201 rotates around the positioning pin 203 under the drive of the cylinder 5, the force end of the lever arm 201 pushes the first push rod 204, and the amplified force is accurately transmitted to the sliding body 302 of the slide rail mechanism 3. When the first push rod 204 pushes the sliding body 302, the sliding body 302 slides along the side wall track of the slide rail base 301. The sliding of the sliding body 302 applies the force transmitted by the lever arm 201 to the bearing outer ring of the deep groove ball bearing 14, so that the bearing outer ring of the deep groove ball bearing 14 is elastically deformed controllably, and the controllable elastic deformation range of the bearing outer ring of the deep groove ball bearing 14 is about 0.1-0.3mm, and the steel ball groove is temporarily expanded. The lever mechanism 2 amplifies the pushing force of the cylinder 5 by accurately controlling the lever ratio of the pushing force amplification, and converts the smaller cylinder pushing force into larger force, so as to realize accurate force application to the bearing outer ring of the deep groove ball bearing 14. The slide rail mechanism 3 stably and uniformly applies the force transmitted by the lever arm 201 to the bearing outer ring of the deep groove ball bearing 14. The ratio of the output force of the lever mechanism 2 to the applied force is 3-5:1, and by accurately controlling the deformation amount, the damage to the bearing caused by forced pressing, such as scratching of the steel ball or plastic deformation of the bearing outer ring, is effectively avoided. After the bearing is elastically deformed accurately, the steel ball track of the bearing outer ring of the deep groove ball bearing 14 is expanded, and after the steel ball groove is expanded, the last few steel balls can be easily put into the steel ball track by artificial, so that the problem of scratching of the steel ball caused by forced pressing in the traditional assembly is avoided.

[0055] At the same time, after the cylinder piston rod drives the cylinder top block 7 to shrink and reset, the second push column 205 loses the pushing force, at this time, the first push rod 204 also loses the pushing force, and after the lever arm 201 is reset, the slide rail base 301 is pulled back to the original position by the reset spring, and the sliding body 302 of the slide rail mechanism 3 also returns to the original position with the slide rail base 301, and the bearing outer ring of the deep groove ball bearing 14 loses the extrusion force. Since the bearing outer ring only elastically deforms, it can return to the original shape, so that the performance of the bearing, such as vibration value and rotation flexibility, is not affected. The radial deformation amount of the deep groove ball bearing outer ring can be accurately controlled to be between-0.02mm and +0.02mm, which significantly improves the accuracy and precision of the control force application, and meets the actual use requirements.

[0056] As shown in Table 1, the manual sleeve operation is compared with the use of the deep groove ball bearing sleeve and ball assembling device, and the specific comparison results are as follows: Table 1 is a quantitative effect comparison table of manual sleeve operation and use of the deep groove ball bearing sleeve and ball assembling device

[0057]

[0058] As can be seen from Table 1, using the deep groove ball bearing combined sleeve ball device of the utility model, the work efficiency and ball assembling quality of the combined sleeve ball operation are greatly improved compared with manual operation, and the labor cost and maintenance cost are greatly reduced, therefore, the quality and efficiency of the combined sleeve ball process of the deep groove ball bearing combined sleeve ball device are superior to manual operation.

[0059] In conclusion, the utility model realizes precise force exertion under low energy consumption by the temporarily enlarged steel ball groove of the outer ring controllable elastic deformation and the combination of lever mechanics amplification and pneumatic control, fundamentally solves the problems of steel ball scratch and assembly efficiency bottleneck. The deep groove ball bearing combined sleeve ball device of the utility model has passed the actual test and verification of the prototype machine, the daily average capacity is 1550 sets, CPK is greater than or equal to 1.6, and the device has the advantages of advanced technology, economy and engineering practicability, and provides a standardized and intelligent process upgrading scheme for the bearing manufacturing industry.
