Nonstandard bearings are often used in areas where standard bearings cannot or cannot be used conveniently, such as where the mounting structure does not allow, where the mounting space does not allow, and the like. Therefore, some non-standard bearings are designed to perform the bearing task.

In some fields where a large number of non-standard bearings are used, such as the automotive field, since the number of non-standard bearings used is large, an automatic machine is required for assembly to improve the production efficiency and the product consistency. In addition, since the dimensions of the various components of the non-standard bearing are not necessary for the non-standard bearing, the compatibility of the automated assembly machine is also very important to reduce the cost of the product.

Detailed Description

Specific embodiments of the present invention will be described in further detail below based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

Please refer to fig. 1 to 5, which are schematic structural diagrams of a non-standard bearing assembly system according to the present invention. The nonstandard bearing assembling system comprises a machine table 10, a base conveying mechanism 20 arranged on the machine table 10, a base positioning mechanism 30 arranged on the machine table 10 and positioned at the side of the base conveying mechanism 20, and a gasket assembling mechanism 40 arranged on the machine table 10 and positioned at the side of the base conveying mechanism 20. It is understood that the non-standard bearing assembly system may also include other functional structures, such as assembly components, such as fasteners, mounting components, electrical connection components, etc., which are well known to those skilled in the art and will not be described herein.

It should be noted that the non-standard bearing 50 assembled by the non-standard bearing assembling system includes a base 51, a spacer 52 disposed in the base 51, a bearing 53 disposed on the spacer 52, a chuck 54 for clamping the bearing 53, and a fixing member 55 for fixing the chuck 54. The spacer 52, the bearing 53, and the chuck 54 are sequentially disposed in the base 51. The fixing member 55 fixes the spacer 52, the bearing 53, and the chuck 54 therebetween together with the base 51. The spacer 52 may be a self-lubricating sliding plate in order to make the bearing 53 slide more easily and reduce noise. The bearing 53 has a center hole in which a shaft can be inserted for rotation. The base 51 has a recess for accommodating the pad 52, the bearing 53, and the chuck 54, and has two side arms, and two mounting holes are formed on the two side arms. The nonstandard bearing can be installed in an application such as an automobile through the installation hole.

The machine 10 is used for carrying or accommodating various functional modules, such as the base conveying mechanism 20, the base positioning mechanism 30, the gasket assembling mechanism 40, and the like, and therefore, the structure and shape thereof can be set according to actual needs, and further description thereof is omitted.

The base conveying mechanism 20 is used for conveying the bases 51, that is, the bases 51 are sequentially conveyed into the nonstandard bearing assembly system one by one. The base conveying mechanism 20 comprises a vibration feeding tray 21, a feeding groove 22 connected with the vibration feeding tray 21, a conveying belt 23 connected with the feeding groove 22, and a stepping motor 24 for driving the conveying belt 23 to move. The vibratory feed tray 21 is a prior art device that vibrates to align the material in a row and pushes the base 51 forward into the feed chute 22. The shape of the feeding chute 22 can be designed according to the shape of the base 51, and in this embodiment, the feeding chute 22 has a trough-shaped structure and has two material clamping rods 221 respectively disposed on two side walls of the feeding chute 22. The presence of the jamming bar 221 causes the base 51 entering the chute 22 to be sequentially held in a fixed position, i.e., in close proximity to the jamming bar 221. The base positioning mechanism 30 is advantageously clamped in position by virtue of at least one base 51 being fixed in a fixed position. The conveyer belt 23 is connected to the feed chute 22, and is used for conveying the bases 51 conveyed by the base positioning mechanism 30, and respectively conveying the bases 51 to different stations, such as a gasket station, a bearing station, etc., at certain intervals according to the actual conditions. The stepping motor 24 is a prior art, and can output torque at certain intervals according to actual needs, so as to drive the conveying belt 23 to convey the base 51 at certain intervals.

The base positioning mechanism 30 includes a two-dimensional driving mechanism 31 disposed on the machine table 10, a feeding plate 32 driven by the two-dimensional driving mechanism 31, and a feeding clamp 33 disposed on the feeding plate 32. The two-dimensional driving mechanism 31 includes an X-axis driving mechanism 311, and a Y-axis driving mechanism 312. The driving direction of the X-axis driving mechanism 311 is the same as the conveying direction of the conveying belt 23, and it is used to convey the base 51 from the feed chute 22 to the conveying belt 23 at a certain distance and interval. The driving direction of the Y-axis driving mechanism 312 is perpendicular to the conveying direction of the conveying belt 23, and is used for driving the feeding clamp 32 to clamp the materials, and after one material is conveyed, driving the feeding clamp 32 to retract, i.e. to move away from the conveying belt 23, so as to facilitate the gasket assembly mechanism 40 to assemble the gasket 52. The X, Y

axle moving mechanisms

311, 312 should be prior art in structure and composition, and include driving devices such as air cylinder or motor, screw, and guide rail pair, etc., which will not be described herein. The X-axis driving mechanism 311 is disposed on the Y-axis driving mechanism 312, and the feeding plate 32 is disposed on the X-axis driving mechanism 311. The feeding plate 32 is used for arranging the feeding clamp 33, and it is naturally conceivable that other mechanisms, such as a pressing device and the like, may be arranged on the feeding plate 32 according to needs, and the arrangement may be according to actual needs, and will not be described herein again. The feeding clamp 33 can be set according to actual requirements, and in this embodiment, the base 51 has two mounting holes, so the feeding clamp 33 has two insertion rods. And the two inserting rods are respectively inserted into the two mounting holes during conveying. Of course, it is understood that, in order to fix the feeding clamp 33 and the base during transportation, the feeding clamp 33 may be an electromagnetic plunger, i.e., when transportation is performed, electricity is applied to generate magnetic force to attract the base 51 to prevent it from falling. The base 51 in the feeding chute 22 can be conveyed to a preset position of the conveying belt 23 to be positioned by the base positioning mechanism 30, so that the gasket 52 can be assembled by the gasket assembling mechanism 40.

The gasket assembly mechanism 40 includes a base 41 disposed on the machine platform 10, a reciprocating drive mechanism 42 disposed on the base 41, a slide mechanism 43 disposed on the base 41 and driven by the reciprocating drive mechanism 42, and a gasket assembly mechanism 44 disposed on the slide mechanism 43. The base 41 can be designed in its structure and shape according to actual needs, and will not be described in detail here. The reciprocating drive mechanism 42 includes an actuator 421 provided on the base 41, a rocking plate 422 provided on the base 41 and driven by the actuator 421, and a link 423 connecting the rocking plate 422 and the slide mechanism 43. The driver 421 includes an output terminal 424, and a base terminal 425. The driver 421 can be a cylinder, which can drive the output end 424 to extend and retract between inflation and suction, so as to achieve the purpose of reciprocating driving. The output end 424 is rotatably connected to the wobble plate 422, and the base end 425 is fixedly connected to the base 41. The wobble plate 422 is a triangular plate. The triangular plate has a first angle 4221, a second angle 4222, and a third angle 4223. The first angle 4221 is pivotally connected to the base 41 so that the swing plate 422 can rotate about the first angle 4221. The second angle 4222 is rotatably connected to the output end 424 of the driver 421 and is driven by the driver 421 to swing back and forth. In order to connect the second angle 4222 to the output 424 of the driver 421, a connecting piece 426 is provided between the second angle 4222 and the output 424. The connector 426 has a socket at one end for connection to the output 424 and two ears and a shaft at the other end. The second angle 4222 is inserted between the two ears and the shaft rotatably connects the second angle 4222 with the connecting member 426. The link 423 is connected between the third angle 4223 and the sliding mechanism 43, and it is conceivable that the link 423, the third angle 4223 and the sliding mechanism 43 may be connected by a shaft, which is prior art and will not be described herein again. The length of the link 423 will determine the sliding distance of the sliding mechanism 43, and thus the compatibility of the assembly system can be improved by setting the length of the link 423. In order to ensure the accuracy of the movement of the sliding mechanism 43, the extending direction of the connecting rod 423 is alternately switched between parallel and perpendicular to the sliding direction of the sliding mechanism 43 under the driving of the swing plate 42, that is, the gasket assembly mechanism 40 inserts the gasket 52 into the base 51 when the extending direction of the connecting rod 423 is perpendicular to the sliding direction of the sliding mechanism 43, and the gasket assembly mechanism 40 sucks the inserted gasket 52 when the extending direction of the connecting rod 423 is parallel to the sliding direction of the sliding mechanism 40, so that the base positioning mechanism 30 and the gasket assembly mechanism 40 organically and orderly insert the gasket 52 into the corresponding position of the base 51 from each base positioning mechanism 30. The slide mechanism 43 includes a guide rail 431 provided on the base 41, and a slider 432 provided on the guide rail 431. The link 423 is rotatably connected to the slider 432, so that the slider 432 reciprocates by the link 423. The spacer assembling mechanism 44 is provided on the slider 432 and includes an air cylinder 441 provided on the slider 432, a link plate 442 driven by the air cylinder 441, and an electromagnetic suction cup 443 provided on the link plate 442. The cylinder 441 is used for driving the link plate 442 to reciprocate, and the moving direction of the cylinder is perpendicular to the conveying direction of the conveying belt 23. The electromagnetic suction cup 443 is used to suck the pad 52, and can suck or put down the pad 52 by charging and discharging. It is contemplated that different suction cups 443, such as pneumatic suction cups, may be used depending on the material of the pad 52.

It should be noted that the non-standard bearing assembling system further includes a bearing assembling mechanism, a chuck assembling mechanism, a fixing member assembling mechanism, a pressing mechanism, and the like, which are disposed on the machine table 10, and the bearing 53, the chuck 54, and the fixing member 55 can be placed on the base 51 by a mechanism similar to the pad assembling mechanism 40 to complete the whole non-standard bearing. The reciprocating driving mechanism used by the bearing assembling mechanism, the chuck assembling mechanism and the fixing part assembling mechanism can be the same as the reciprocating driving mechanism 42, and different clamping devices can be selected according to different parts. Accordingly, these mechanisms are not described in detail herein, as would be understood by one of ordinary skill in the art.

Compared with the prior art, the nonstandard bearing assembly system provided by the invention has the advantages that the base 51 is conveyed from the base conveying mechanism 20 to the fixed position through the base positioning mechanism 30, so that the gasket assembly mechanism 40 can conveniently place the gasket into the fixed position of the base 51. The gasket assembly mechanism 40 includes a reciprocating drive mechanism 42, the reciprocating drive mechanism 42 includes a wobble plate 422, and the wobble plate 422 is a triangular plate. The triangular plate has a first angle 4221, a second angle 4222, and a third angle 4223. The first angle 4221 is rotatably connected to the base 41, the second angle 4222 is rotatably connected to the output end 424 of the driver 421 and reciprocally swings under the driving of the driver 421, and one end of the connecting rod 423 is rotatably connected to the third angle 4223, and the other end thereof is rotatably connected to the sliding mechanism 43. The extending direction of the link 423 is alternately switched between parallel and perpendicular to the sliding direction of the sliding mechanism 43 by the driving of the rocking plate 422. The pad assembly mechanism 40 inserts the pad 52 into the base 51 when the extending direction of the link 422 is perpendicular to the sliding direction of the sliding mechanism 43, and the pad assembly mechanism 40 sucks the fed pad 52 when the extending direction of the link 423 is parallel to the sliding direction of the sliding mechanism 43, so that the base positioning mechanism 30 and the pad assembly mechanism 40 organically and orderly insert the pad 52 into the corresponding position of the base 51 fed by each base positioning mechanism 30.
