Description

Technical Field

[0001] The utility model relates to the field of rotor bearing assembly, in particular to a conveying device used for rotor bearing assembly. Background Art

[0002] A rotor bearing is a special bearing used specifically in electric motors. The bearing used in an electric motor is a part that supports the shaft. It can guide the rotation of the shaft and also bear the idling parts on the shaft. When assembling the current rotor bearing, a conveyor belt is set under the multiple placement and press-fitting mechanisms of the bearing. The outer shell of the bearing is placed on top of the conveyor belt. Then, under the action of the conveyor belt, it moves under each mechanism in turn to place and press-fit the parts. It is difficult to ensure the accuracy of its movement by placing it directly on the conveyor belt for movement. Due to its small overall weight, when the conveyor device brakes during movement, it can shift its position due to inertia. To this end, we have designed a conveying device for rotor bearing assembly. Utility Model Content

[0003] In order to solve the technical problem of difficulty in ensuring the accuracy of movement, the utility model provides a conveying device for assembling rotor bearings.

[0004] The utility model is implemented by the following technical solution: a conveying device for assembling rotor bearings, comprising a machine platform, a placing slide is installed above the machine platform, two guide bars are symmetrically arranged above the placing slide, an entry mechanism and a discharge mechanism are arranged on the left and right sides of the machine platform, the entry mechanism and the discharge mechanism are in contact with the left and right ends of the placing slide respectively, and the entry mechanism and the discharge mechanism are both a conveyor belt, wherein the entry mechanism brings the bearing close to the placing slide, and the discharge mechanism keeps the bearing away from the placing slide;

[0005] A conveying mechanism and a positioning mechanism are installed above the machine, and the conveying mechanism and the positioning mechanism are respectively located on the front side and the rear side above the sliding plate.

[0006] As a further improvement of the above scheme, the conveying mechanism includes a horizontal cylinder installed above the machine, the push rod of the horizontal cylinder is connected to a horizontal plate, the horizontal plate is slid left and right above the machine, two groups of vertical cylinders are installed above the horizontal plate, and a transverse plate is installed on the push rod of the vertical cylinder. A plurality of push plates with equal intervals are installed above the transverse plate, and the push plates extend backward to just above the slide plate. The number and position of the vertical cylinders are changed accordingly according to actual needs. Multiple push plates can move left and right a fixed distance, which is also the distance between two adjacent push plates, thereby causing the bearing above the slide plate to move forward, so that the bearing is below the corresponding process.

[0007] As a further improvement to the above solution, a guide cross bar is suspended above the machine through a bracket, and sliders are symmetrically provided at the lower end of the transverse plate. The sliders are slidably connected to the guide cross bar and can guide the left and right movement of the transverse plate, thereby improving stability and facilitating its left and right movement.

[0008] Two groups of guide vertical rods are symmetrically arranged above the transverse plate, and the transverse plate is slidably sleeved on the two guide vertical rods, which can guide the up and down movement of the transverse plate and improve stability.

[0009] As a further improvement of the above scheme, the positioning mechanism includes two positioning cylinders fixed above the machine table, the push rods of the positioning cylinders are connected to a lifting plate, and a plurality of positioning blocks distributed at equal intervals are installed above the lifting plate, the positioning blocks extend above the placement slide, and the plurality of positioning blocks and the plurality of push plates are staggered. Under the action of the positioning cylinders, the positioning blocks move up and down with the lifting plate. When they move downward and contact the guide bar, the bearing will contact the positioning block during its leftward movement, thereby being able to position it, preventing it from moving excessively, and improving the conveying accuracy.

[0010] Two sets of sliding rods are vertically arranged above the machine platform. The lifting plate passes through the sliding rods through circular holes, and the two are slidably connected to guide them, thereby improving stability.

[0011] As a further improvement of the above solution, the push plate and the positioning block have a V-shaped structure design on the side surface close to the bearing. This structure is simple and effective, and has the characteristics of high repeat positioning accuracy. The upper and lower edges are both chamfered to avoid scratches on the surface when contacting and clamping with the bearing.

[0012] As a further improvement of the above scheme, guide plates are provided on the left and right sides above the entry mechanism and the discharge mechanism, and the left and right ends of the guide bar on the front side of the placement slide extend outward to above the entry mechanism and the discharge mechanism, so that the support can accurately enter the placement slide along the guide bar and can move out the placement slide.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model provides an entry mechanism and an exit mechanism on the left and right sides above the machine, and cooperates with a placement slide, a conveying mechanism, and a positioning mechanism provided between the two, so that the outer ring of the rotor bearing can be moved to a specified position, and the position accuracy of each movement is high, which facilitates subsequent assembly operations;

[0015] 2. By setting up a positioning mechanism, the rotor bearing is fixed every time it moves, and after moving to the specified position, the positioning mechanism cooperates with the conveying mechanism to position and fix it, thereby facilitating the placement and assembly of the corresponding inner ring and rolling body. Afterwards, it is moved to the discharge mechanism under the action of the conveying mechanism and moved to the next process, thereby improving the assembly accuracy.

[0022] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] Example:

[0024] Please combine Figures 1-4 The present embodiment is a conveying device for assembling rotor bearings, comprising a machine platform 1, a placement slide 5 mounted above the machine platform 1, two guide bars symmetrically arranged front and rear above the placement slide 5, an entry mechanism 2 and a discharge mechanism 3 arranged on the left and right sides of the machine platform 1, the entry mechanism 2 and the discharge mechanism 3 respectively contact the left and right ends of the placement slide 5, and the entry mechanism 2 and the discharge mechanism 3 are both conveyor belts, wherein the entry mechanism 2 brings the bearing close to the placement slide 5, and the discharge mechanism 3 moves the bearing away from the placement slide 5;

[0025] A conveying mechanism 4 and a positioning mechanism 6 are installed above the machine 1 . The conveying mechanism 4 and the positioning mechanism 6 are respectively located on the front side and the rear side above the slide 5 .

[0026] The conveying mechanism 4 includes a horizontal cylinder 41 installed above the machine 1, and the push rod of the horizontal cylinder 41 is connected to a horizontal plate 42. The horizontal plate 42 is sliding left and right above the machine 1. Two groups of vertical cylinders 47 are installed above the horizontal plate 42, and a transverse plate 44 is installed on the push rod of the vertical cylinder 47. A plurality of groups of equally spaced push plates 45 are installed above the transverse plate 44. The push plates 45 extend backward to just above the slide 5. The number and position of the vertical cylinders 47 are changed accordingly according to actual needs. Multiple push plates 45 can move left and right a fixed distance, which is also the distance between two adjacent push plates 45, thereby causing the bearing above the slide 5 to move forward, so that the bearing is below the corresponding process.

[0027] A guide crossbar 43 is suspended above the machine 1 by a bracket, and a slider is symmetrically provided at the lower end of the transverse plate 42. The slider is slidably connected to the guide crossbar 43, which can guide the left and right movement of the transverse plate 42, thereby improving stability and facilitating its left and right movement.

[0028] Two sets of guide vertical rods 46 are symmetrically arranged above the transverse plate 42. The transverse plate 44 is slidably sleeved on the two guide vertical rods 46, which can guide the up and down movement of the transverse plate 44 and improve stability.

[0029] The positioning mechanism 6 includes two positioning cylinders 64 fixed above the machine table 1. The push rods of the positioning cylinders 64 are connected to a lifting plate 61. A plurality of equally spaced positioning blocks 62 are installed above the lifting plate 61. The positioning blocks 62 extend above the placement slide 5. The plurality of positioning blocks 62 and the plurality of push plates 45 are staggered. The positioning blocks 62 move up and down with the lifting plate 61 under the action of the positioning cylinders 64. When the positioning blocks 62 move downward and contact the guide bar, the bearing will contact the positioning blocks 62 during its leftward movement, thereby positioning the bearing and preventing it from excessive movement, thereby improving the conveying accuracy.

[0030] Two sets of sliding rods 63 are vertically arranged above the machine 1. The lifting plate 61 passes through the sliding rods 63 through the circular holes, and the two are slidably connected to guide them, thereby improving stability.

[0031] The push plate 45 and the positioning block 62 have a V-shaped surface close to the bearing. This structure is simple and effective, and has the characteristics of high repeatability and positioning accuracy. The upper and lower edges are both rounded to avoid scratches on the surface when in contact with the bearing and clamped.

[0032] Guide plates are provided on the left and right sides above the entry mechanism 2 and the discharge mechanism 3, and the left and right ends of the guide bar on the front side of the placement slide 5 extend outward to above the entry mechanism 2 and the discharge mechanism 3, so that the support can accurately enter the placement slide 5 along the guide bar and can move out the placement slide 5.

[0033] The implementation principle of a conveying device for assembling rotor bearings in an embodiment of the present application is as follows: in actual use, the machine platform 1 is directly below the assembly mechanism, wherein the assembly mechanism includes a placement and press-fitting mechanism for the inner ring and rolling elements. The outer ring enters above the placement slide 5 under the action of the entry mechanism 2, and then moves to the right by a unit distance each time under the action of the conveying mechanism 4, so that the outer ring is placed below the placement and press-fitting mechanism for the inner ring and rolling elements, so that the corresponding processes can be assembled one by one;

[0034] Under the action of the positioning mechanism 6, each movement is fixed, and after moving to the designated position, the positioning mechanism 6 cooperates with the conveying mechanism 4 to further position and fix it, thereby facilitating the placement and assembly of the corresponding inner ring and rolling element. Afterwards, under the action of the conveying mechanism 4, it is moved to the discharge mechanism 3 and moved to the next process;

[0035] When the conveying mechanism 4 and the positioning mechanism 6 are working, they first enter the mechanism 2 so that the outer ring of the rotor bearing enters the left side above the placement slide 5. At this time, the positioning cylinder 64 causes the lifting plate 61 and the positioning block 62 to move upward as a whole, and the vertical cylinder 47 also causes the push plate 45 to move upward, and the positioning block 62 and the push plate 45 are all above the outer ring. Then, the multiple push plates 45 move to the left under the action of the horizontal cylinder 41, and the push plates 45 move downward again under the action of the vertical cylinder 47;

[0036] Afterwards, the push plate 45 moves to the right as a whole again under the action of the transverse cylinder 41. During the process of moving to the right (after the previous bearing is placed on the right side of the positioning block 62), the positioning block 62 moves downward, and the outer ring of the bearing contacts the positioning plate. At this time, the supporting outer ring can be fixed between the positioning block 62 and the push plate 45, and then it can be positioned and clamped, thereby facilitating subsequent assembly operations.

[0037] By arranging an entry mechanism 2 and an exit mechanism 3 on the left and right sides above the machine platform 1, and cooperating with a placement slide 5, a conveying mechanism 4, and a positioning mechanism 6 arranged therebetween, the outer ring of the rotor bearing can be moved to a specified position with high positioning accuracy each time, facilitating subsequent assembly operations.

[0038] Through the positioning mechanism 6, the rotor bearing is fixed every time it moves, and after moving to the specified position, the positioning mechanism 6 cooperates with the conveying mechanism 4 to position and fix it, thereby facilitating the placement and assembly of the corresponding inner ring and rolling body. Afterwards, it is moved to the discharge mechanism 3 under the action of the conveying mechanism 4 and moved to the next process, thereby improving the assembly accuracy.

[0039] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
