Description
Technical Field
[0001] The utility model relates to the technical field of automated production, in particular to a multi-bearing press-fitting device. Background Art
[0002] The motor is composed of a rotor and a stator. The rotor rotates relative to the stator.

[0033] Ginseng Figures 1 to 13 As shown, a multi-bearing press-fitting device comprises a horizontally arranged workbench 1 and a bearing storage mechanism 2, a bearing feeding mechanism 3 and a bearing press-fitting mechanism 4 arranged on the workbench 1, the bearing storage mechanism 2 comprises a storage rack, a plurality of parallel storage troughs are arranged in the storage rack, a feeding block is slidably arranged in the storage trough, a discharge trough is arranged at one end of the storage trough close to the bearing feeding mechanism 3, the bearing feeding mechanism 3 comprises a clamping jaw 31 arranged corresponding to the discharge trough and a moving mechanism for driving the clamping jaw 31, the bearing press-fitting mechanism 4 comprises a rotor shaft placing jig 41 and a first bearing placing jig 42 and a second bearing placing jig 43 arranged on both sides of the rotor shaft placing jig 41, wherein the first bearing placing jig 42 is slidably arranged on the workbench 1 through a press-fitting mechanism 44, and the rotor shaft placing jig 41, the first bearing placing jig 42 and the second bearing placing jig 43 are coaxially arranged.
[0034] In this technical solution, conventional PLC and other control devices, as well as cables, air pipes, wire ducts and tank chains are also provided on the outside. The specific structure and control principle, etc., all belong to the prior art and will not be elaborated here. Conventional process holes and chamfers are provided on the surface of the parts to facilitate processing and measurement. The workbench is horizontally arranged through profiles and table foot bolts. The storage trough of the storage rack is used to place bearings. Multiple storage troughs are used to place bearings of the same or different specifications, or bearings of different specifications are arranged at intervals in a single storage trough. The loading block pushes the bearing in the corresponding storage trough to the discharge trough, the clamping claw clamps the corresponding bearing, and moves it to the corresponding first bearing placement jig and second bearing placement jig through the moving mechanism (the bearing placed in the first bearing placement jig is called the first bearing, and the bearing placed in the second bearing placement jig is called the second bearing). The press-fitting mechanism is used to press the bearings at both ends of the rotor shaft, that is, the bearings required to be press-fitted at the two ends of the rotor shaft are placed in the first bearing placement jig and the second bearing placement jig respectively. The rotor shaft is placed in the rotor shaft placement jig (the rotor core and the commutator are pre-installed on the rotor shaft) manually or by an external manipulator. The press-fitting mechanism pushes the first bearing placement jig to move along the axial direction of the rotor shaft. The first bearing in the first bearing placement jig is sleeved on one end of the rotor shaft, and drives the rotor shaft to slide along its rotor shaft placement jig toward the second bearing placement jig, that is, the other end of the rotor shaft moves toward the second bearing in the second bearing placement jig until the press-fitting of the bearings at both ends of the rotor shaft is completed. The press-fitting mechanism is reset, and the rotor shaft with the bearings at both ends pressed is taken out. The multi-bearing press-fitting device has a compact structure, and can press-fit the bearings required at both ends of the rotor shaft at the same time, and can press-fit bearings of different models, thereby improving production efficiency.
[0035] For example, see Figures 1 to 5As shown, the material storage rack includes a material storage plate 21, and the bottom surfaces of both ends of the material storage plate 21 are fixed to the workbench 1 through support seats 22 respectively. A plurality of grid bars 23 are arranged on the top surface of the material storage plate 21, and material storage grooves are formed between adjacent grid bars 23 and the material storage plate 21. The loading block 24 slides in the corresponding material storage groove. A limit plate 25 is arranged on the top surface of one end of the material storage plate 21 close to the bearing loading mechanism 3, and a discharge groove is formed between the limit plate 25 and the end surface of the grid bar 23 and the material storage plate 21.
[0036] In this technical solution, five bars are arranged on the top of the storage plate through bolts and positioning pins to form four storage slots. Figure 2 and Figure 3 A grid bar and a loading block are omitted in the process, and a bearing of one specification is arranged in every two storage troughs, that is, the storage rack stores two specifications of bearings, which correspond to the bearings required to be pressed at both ends of the rotor shaft. The loading block slides along the storage trough to push the bearing in the corresponding storage trough into the storage trough, which is convenient for the clamp to clamp; a limited height plate is arranged on the top of one side of the grid bar close to the limit plate, and a height limiting boss corresponding to the storage trough is protruded from the bottom surface of the height limiting plate to avoid squeezing between adjacent bearings and causing the bearings to be squeezed out of the storage trough. The limit plate is an L-shaped structure, and its horizontal part is fixed to the storage plate by bolts, etc., and the vertical part and the end of the grid bar are arranged at intervals, and sensors corresponding to the storage troughs are arranged in the vertical part to sense whether the bearing enters the discharge trough. The sensor is aligned with the end cover of the bearing, etc., and the corresponding sizes are different for different bearing specifications. A groove is processed on the top surface of the storage plate to avoid the sensor being in the center of the corresponding bearing, which makes it impossible to identify whether the bearing enters the discharge trough.
[0037] For example, see Figures 1 to 5 As shown, ejecting cylinders 26 corresponding to the material storage slots are provided below the material storage plate 21 , and the loading block 24 slides through the material storage plate 21 and is connected to the slider corresponding to the ejecting cylinder 26 .
[0038] In this technical solution, the lifting cylinder can be an existing rodless cylinder, and both ends are fixed to the corresponding support seats by bolts, etc., and a through hole corresponding to the mounting bolts of the lifting cylinder is provided in the storage plate. The lifting cylinder can be disassembled and assembled without disassembling the storage plate. Conventional devices such as an air source regulating valve are provided on the outside of the outermost grid bar, and are respectively connected to the lifting cylinder through the valve plate to provide a power source for the lifting cylinder.
[0039] For example, see Figures 1 to 5 As shown, the loading block 24 is an L-shaped structure, including a connecting portion connected to the slider of the lifting cylinder 26 and a lifting portion parallel to the top surface of the storage plate 21, and the storage plate 21 is provided with a first avoidance groove corresponding to the connecting portion, and the bottom end side surface of the corresponding grid bar 23 is recessed with a second avoidance groove corresponding to the connecting portion, and a lifting boss protrudes from the top surface of the lifting portion.
[0040] In this technical solution, the first avoidance groove in the material storage plate is located below the corresponding grid bar to avoid interfering with the placement and movement of the bearing. The second avoidance groove corresponding to the first avoidance groove is arranged on the bottom surface of the grid bar to accommodate the sliding of the loading block. After the loading block slides through the first avoidance groove and the second avoidance groove, it is connected to the slider of the lifting cylinder, thereby driving the loading block through the lifting cylinder. By setting the lifting boss, the contact area between the loading block and the bearing is increased, thereby improving the uniformity of the bearing force.
[0041] For example, see Figure 1 and Figure 6 As shown, the clamp 31 includes a finger cylinder 311 and a clamp 312 respectively driven and connected to the finger cylinder 311, and a V-shaped groove is provided on the inner side of the clamp 312. The moving mechanism includes a gantry straddling the bearing storage mechanism 2, a first electric cylinder 32 fixed to the gantry, a second electric cylinder 33 fixed to the slider of the first electric cylinder 32, and a lifting cylinder 34 fixed to the slider of the second electric cylinder 33. The finger cylinder 311 is fixed to the push plate of the lifting cylinder 34.
[0042] In this technical solution, the first electric cylinder and the second electric cylinder both use existing servo electric cylinders, which cooperate with sensors, etc. to achieve start and stop at any position. The specific structure and principle belong to the existing technology and will not be described in detail here. The V-groove set on the inner side of the clamp can clamp the first bearing and the second bearing of different specifications at the same time. In order to reduce the moving distance of the clamp, the discharge trough and the first bearing placement jig are aligned, that is, when the first bearing is loaded, the second electric cylinder does not need to move. When taking the material, the clamp is moved to the corresponding position of the discharge trough through the action of the first electric cylinder and the lifting cylinder, and the corresponding first bearing or second bearing is clamped. The lifting cylinder is reset, and the clamp holding the first bearing is moved to the first bearing placement jig through the first electric cylinder, and the clamp holding the second bearing is moved to the second bearing placement jig through the first electric cylinder and the second electric cylinder. The lifting cylinder drives the clamp to descend, and the clamp releases the corresponding first bearing or second bearing, and the first bearing and the second bearing fall into the corresponding first bearing placement jig and second bearing placement jig respectively.
[0043] For example, see Figure 1 as well as Figures 7 to 9 As shown, the rotor shaft placement fixture 41 includes a placement block 412 connected to the workbench 1 through a support rod 411, the top surface of the placement block 412 is provided with a placement groove corresponding to the rotor shaft, the support rod 411 is connected to an adjustment block 413 parallel to the workbench 1, and the adjustment block 413 is provided with a first fine-tuning bolt 414 that abuts against the workbench 1.
[0044] In this technical solution, a semicircular groove corresponding to the rotor core is provided on the top surface of the placement block as a placement groove for limiting the rotor shaft. The rotor shaft is radially limited in cooperation with the deadweight of the rotor shaft. The bottom of the support rod is connected to the workbench through connecting screws. When it is necessary to adjust the installation height of the placement block, the connecting screws at the bottom of the support rod are loosened, and then the first fine-tuning bolt is used to act on the workbench to adjust the gap between the adjustment block and the workbench. The placement block can be driven to rise and fall through the support rod. After the position adjustment is completed, the connecting screws at the bottom of the connecting rod and the self-locking nut on the first fine-tuning bolt are tightened to ensure the coaxiality of the rotor shaft with the first bearing and the second bearing, thereby improving the press-fitting accuracy. Both sides of the placement block are provided with corresponding sensors for confirming whether the rotor shaft is placed in the placement groove. Three through holes are provided on the bottom surface of the placement block, and magnets are installed to improve the stability of the placement of the rotor shaft.
[0045] For example, see Figure 1 , Fig.10 and Fig.11 As shown, the pressing mechanism 44 includes a mounting seat 441 connected to the workbench 1, a third electric cylinder 442 fixed to the mounting seat 441, and a slide 443 drivingly connected to the third electric cylinder 442, and the first bearing placement fixture 42 is fixed to the side of the slide 443 close to the rotor shaft placement fixture 41.
[0046] In this technical solution, the mounting seat is of a conventional structure and is fixed to the workbench by mounting screws. In order to reduce the shear force on the mounting screws during the press-fitting process, a key (not shown) perpendicular to the press-fitting direction is embedded between the bottom surface of the mounting seat and the top surface of the workbench. The third electric cylinder drives the first bearing placement jig to move along the axial direction of the rotor shaft through the slide.
[0047] For example, see Figure 1 , Fig.10 and Fig.11 As shown, the slide 443 includes a base plate slidably connected to the mounting base 441 through a guide rail and a connecting plate vertically fixed to the top surface of the base plate. The two sides of the connecting plate are respectively connected to the third electric cylinder 442 and the first bearing placement fixture 42 through a first connecting head 444 and a second connecting head 445.
[0048] In this technical solution, the third electric cylinder is a conventional servo electric cylinder, the output end of which passes through the corresponding side plate of the mounting seat and is driven and connected to the slide through a conventional floating joint (first connecting head), thereby driving the slide to move along the axial direction of the rotor shaft. To ensure the smoothness and accuracy of the movement of the slide, the bottom surface of the base plate and the mounting seat are connected by a guide rail.
[0049] For example, see Figure 1 , Fig.10 and Fig.11As shown, the second connecting head 445 is connected to the side of the connecting plate through the adjusting plate 446, the bottom plate is provided with a second fine-tuning bolt that abuts against the bottom surface of the adjusting plate, and the two sides of the connecting plate are respectively provided with third fine-tuning bolts that abut against the side of the adjusting plate through the adjusting seat.
[0050] In this technical solution, the second connecting head is a stepped shaft structure, one end of which is embedded in and adjusted by a plate, and the adjusting plate is fixed to the connecting plate by bolts and gaskets. The installation position of the adjusting plate is adjusted by the second fine-tuning bolt and the third fine-tuning bolt, thereby adjusting the installation position of the second connecting head to ensure the coaxiality of the second connecting head and the rotor shaft placement groove.
[0051] For example, see Figures 10 to 13 As shown, the first bearing placement fixture 42 includes a first connecting seat 421 connected to the second connecting head 445 and a first bearing placement block 422 connected to the first connecting seat 421. The first connecting seat 421 is a hollow stepped shaft structure, and its two ends are respectively embedded in the second connecting head 445 and the first bearing placement block 422. The first bearing placement block 422 is an annular structure, and a first bearing placement boss is protruded from one end of the first bearing placement fixture 422 close to the rotor shaft placement fixture 41. An avoidance groove corresponding to the rotating shaft is arranged in the second connecting head 445, and a first limit block 447 is slidably arranged in the avoidance groove; the second bearing placement fixture 43 includes a second connecting seat connected to the workbench 1 through a mounting block 431 and a second bearing placement block 433 connected to the second connecting seat 432. The second bearing placement block 433 is an annular structure, and a second bearing placement boss is protruded from one end of the first bearing placement fixture 422 close to the rotor shaft placement fixture 41. The mounting block is fixed to the workbench by screws, etc., and a support block 434 is arranged on the side away from the second bearing placement block to ensure its fixing strength.
[0052] In this technical solution, conventional optical fiber counter-radiation sensors are respectively arranged on both sides of the first bearing placement fixture and the second bearing placement fixture through sensor brackets, which are used to sense the corresponding first bearing and second bearing, etc., and magnets are respectively embedded in the first connecting seat and the second connecting seat to improve the stability of the placement of the first bearing and the second bearing. The end faces of the first connecting seat and the second connecting seat are protruding with pressure rings, which are respectively arranged corresponding to the inner rings of the first bearing and the second bearing. The annular parts of the first bearing placement block and the second bearing placement block are respectively provided with locking grooves for easy installation. The first bearing placement boss and the second bearing placement boss are both arc-shaped structures, and their inner diameters are respectively arranged corresponding to the corresponding first bearing and the second bearing. Magnets are embedded in the first bearing placement boss and the second bearing placement boss to improve The stability of the placement of the first bearing and the second bearing is improved, wherein the outer diameter of the first bearing placement boss is smaller than the diameter of the rotor shaft placement groove, and the inner wall is provided with a make-away groove corresponding to the commutator on the rotor shaft to avoid interference with the press-fitting of the first bearing, and the first connecting seat and the second connecting seat are both hollow structures to avoid interference with the rotor shaft, and the rotor shaft must be limited at the corresponding positions, therefore, the first limit block and the second limit block are respectively provided in the second connecting head and the second limit block, the relative position of the rotor shaft and the first bearing is determined by the length of the first limit block, and the relative position of the rotor shaft and the second bearing is determined by the length of the second limit block, and the first limit block and the second limit block of different lengths can be replaced for different rotor press-fitting needs, thereby expanding the application scope of the device.
[0053] In summary, the multi-bearing press-fitting device has a compact structure, can press-fit the bearings required at both ends of the rotor shaft at the same time, and can press-fit bearings of different models, thereby improving production efficiency.
