Description

[0001] The present invention relates to the field of conveying devices, and more specifically to an orbital width adjusting device for a spherical plain bearing conveying device. Background Art

[0002] A spherical plain bearing is a spherical sliding bearing, whose sliding contact surfaces are an inner spherical surface and an outer spherical surface, and it can rotate and swing at any angle during movement. It is made by using a variety of special processing methods such as surface phosphating, chipping, padding, spraying, etc. Spherical plain bearings have the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, good lubrication, etc. Spherical plain bearings are used as components of various mechanical structures and can be used to produce different specifications of machines and components according to their different sizes.

[0003] Since most of the existing mechanical production has been automated, as a kind of part, the production and conveyance of spherical plain bearings on the assembly line need to be automated to improve the production efficiency of related mechanical components. However, due to the spherical surface of the spherical plain bearing, it is not convenient to clamp, so the conveyance of spherical plain bearings on the assembly line is often in a chaotic order and needs to be manually processed before it is convenient to put into use. It is not convenient to control the mechanical claw to grab the bearing through the system, thus resulting in a slowdown in the subsequent production process. Summary of the Invention

[0011] Beneficial effects of the present invention:

[0012] (1) The track width adjustment device of a spherical plain bearing conveying device according to the present invention enables the device to convey spherical plain bearings through the setting of the conveying structure, facilitating the use of spherical plain bearings in the next production process. That is, the spherical plain bearings to be used can be placed in the feeding hopper on the fixed seat, and the bearings in the feeding hopper will continuously be placed on the conveyor belt, and the conveying task of the spherical plain bearings is completed through the conveyor belt. Through the setting of the adjustment structure, the position of the spherical plain bearings can be adjusted during transportation, enabling all spherical plain bearings to be orderly during transportation. That is, when the conveyor belt conveys one spherical plain bearing after another, the two clamping plates will periodically move closer to and away from each other. Therefore, with the continuous movement of the two clamping plates, the spherical plain bearings will eventually be pushed to the middle position of the conveyor belt. The four sliders slide in the four chutes, increasing the distance that the two clamping plates can move, and rubber pads are fixedly connected to both clamping plates, which can prevent the two clamping plates from being deformed by extrusion with the spherical plain bearings during movement.

[0013] (2) The track width adjustment device of a spherical plain bearing conveying device according to the present invention enables the control structure to move through the setting of the driving structure, thereby enabling the movement of the adjustment structure. That is, after the motor is electrically connected to an external power source, the motor can be started. After the motor is started, its output shaft rotates, driving the rotating rod to rotate. When the rotating rod rotates, it can drive the cam to rotate. When the cam rotates, the entire lifting seat will move up and down because it contacts the inner wall of the through hole. When the lifting seat moves up and down, it can drive the fixed seat to move up and down. When the fixed seat moves up and down, it will ultimately drive the two clamping plates to continuously slide back and forth through the first adjusting rod and the second adjusting rod.

[0014] (3) The track width adjustment device of a spherical plain bearing conveying device according to the present invention enables the adjustment structure to move through the setting of the control structure, thereby keeping the transportation of the spherical plain bearings orderly. That is, when the fixed seat moves up and down, it can drive the first adjusting rod and the second adjusting rod to move. The bottom ends of the first adjusting rod and the second adjusting rod will drive the two clamping plates to move periodically during the movement, that is, the two clamping plates will periodically move closer to or away from each other. When the two clamping plates move closer to each other, they will contact the spherical plain bearings being transported on the conveyor belt, thereby pushing all the spherical plain bearings to the middle position on the conveyor belt. In this way, after all the spherical plain bearings pass through a certain distance on the conveyor belt, they will all be in an orderly conveying state. At this time, it is convenient for the subsequent processing machinery to position and grasp the spherical plain bearings through the manipulator, thereby facilitating the subsequent process.

[0015] (4) The track width adjustment device of the spherical plain bearing conveying device according to the present invention, through the setting of the auxiliary structure, enables the spherical plain bearings to be conveyed more conveniently during the conveying process on the conveying structure, and there will be no problem of a large number of spherical plain bearings piling up. That is, after the motor is powered on and started, the lifting seat can finally move up and down. At the same time as the lifting seat moves up and down, since the connecting rod is connected to the lifting seat, when the lifting seat moves up and down, the connecting rod will also move up and down. When the connecting rod moves up and down, it will drive the sliding sleeve to move accordingly, and then the fixed rod and the rubber sleeve will both move up and down. Therefore, the spherical plain bearings originally placed in the feeding hopper will be poured out little by little from the gap between the sliding sleeve and the conveyor belt as the sliding sleeve moves up and down, and thus be conveyed by the conveyor belt. The setting and continuous movement of the sliding sleeve ensure that when a large number of spherical plain bearings are poured into the feeding hopper, they will not be exactly in a jammed state. As long as the sliding sleeve keeps moving, and then the fixed rod and the rubber sleeve keep moving, it can ensure that the spherical plain bearings in the feeding hopper will not block the feeding hopper.

[0027] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0028] As Figure 1 - Figure 9 shown, a track width adjusting device of a spherical plain bearing conveying device according to the present invention includes a base 1, a conveying structure 2, an adjusting structure 3, a driving structure 4, a control structure 5 and an auxiliary structure 6. The conveying structure 2 for conveying spherical plain bearings is connected to the base 1 for moving spherical plain bearings. The adjusting structure 3 for adjusting the position of spherical plain bearings during transportation according to different sizes of spherical plain bearings is connected to the base 1. The driving structure 4 for controlling the movement of the adjusting structure 3 is connected to the base 1. The control structure 5 for controlling the movement of the driving structure 4 is connected to the driving structure 4. The auxiliary structure 6 for making the whole conveying process more convenient is connected to the driving structure 4.

[0029] Specifically, the conveying structure 2 includes a connecting seat 21, a feeding hopper 22 and a conveyor belt 23. The connecting seat 21 is fixedly connected to the base 1. The feeding hopper 22 is fixedly connected to the connecting seat 21. The conveyor belt 23 is provided on the base 1. One end of the conveyor belt 23 is located at the bottom of the feeding hopper 22. Spherical plain bearings to be used can be placed into the feeding hopper 22 on the connecting seat 21. The bearings in the feeding hopper 22 will be continuously placed on the conveyor belt 23, and the conveying task of spherical plain bearings is completed through the conveyor belt 23.

[0030] Specifically, the adjustment structure 3 includes clamping plates 31, rubber pads 32, sliders 33 and chutes 34. Two clamping plates 31 are slidably connected to the base 1, and the two clamping plates 31 are respectively located on both sides of the conveyor belt 23. The rubber pads 32 are fixedly connected to both clamping plates 31, and the two rubber pads 32 are symmetrically arranged. Two sliders 33 are fixedly connected to both clamping plates 31. Four chutes 34 are formed in the base 1, and the four sliders 33 are respectively slidably connected to the four chutes 34. The four sliders 33 are all in a "U" - shaped structure. When the conveyor belt 23 conveys one joint bearing at a time, the two clamping plates 31 will periodically move closer to and away from each other. Therefore, with the continuous movement of the two clamping plates 31, the joint bearing will eventually be pushed to the middle position of the conveyor belt 23. The four sliders 33 slide in the four chutes 34, increasing the distance that the two clamping plates 31 can move. Moreover, the rubber pads 32 are fixedly connected to both clamping plates 31, which can prevent the two clamping plates 31 from being deformed by extrusion with the joint bearing during movement.

[0031] Specifically, the driving structure 4 includes a support base 41, a motor 42, a slide bar 43, a rotating rod 44, a lifting seat 45, a through - hole 46 and a cam 47. The support base 41 is fixedly connected to the base 1. The motor 42 is fixedly connected to one side of the support base 41. The rotating rod 44 is fixedly connected to the motor 42. The rotating rod 44 passes through the support base 41, and one end of the rotating rod 44 is rotatably connected to the support base 41. The slide bar 43 is slidably connected to the support base 41. The bottom end of the slide bar 43 is fixedly connected to the lifting seat 45. The through - hole 46 is formed in the lifting seat 45. The cam 47 is fixedly connected to the rotating rod 44. The cam 47 is located inside the through - hole 46. The length of the through - hole 46 is greater than twice the length of the cam 47, and the width of the through - hole 46 is greater than the length of the cam 47. After electrically connecting the motor 42 to an external power source, the motor 42 can be started. After the motor 42 is started, its output shaft rotates, driving the rotating rod 44 to rotate. When the rotating rod 44 rotates, it can drive the cam 47 to rotate. When the cam 47 rotates, the entire lifting seat 45 will move up and down because it contacts the inner wall of the through - hole 46. When the lifting seat 45 moves up and down, it can drive the fixed seat 51 to move up and down. When the fixed seat 51 moves up and down, it will finally drive the two clamping plates 31 to slide back and forth continuously through the first adjusting rod 54 and the second adjusting rod 57.

[0032] Specifically, the control structure 5 includes a fixed seat 51, a first connecting seat 52, a first round rod 53, a first adjusting rod 54, a second connecting seat 55, a second round rod 56 and a second adjusting rod 57. One side of the lifting seat 45 is fixedly connected with the fixed seat 51. The two ends of the fixed seat 51 are respectively fixedly connected with the first round rod 53 and the second round rod 56. The first connecting seat 52 and the second connecting seat 55 are respectively fixedly connected to the two clamping plates 31. The first adjusting rod 54 and the second adjusting rod 57 are respectively rotatably connected to the first round rod 53 and the second round rod 56. The first adjusting rod 54 and the second adjusting rod 57 are respectively rotatably connected to the first connecting seat 52 and the second connecting seat 55. The first adjusting rod 54 and the second adjusting rod 57 are symmetrically arranged with respect to the fixed seat 51. After the motor 42 is electrically connected to an external power source, the motor 42 can be started. After the motor 42 is started, its output shaft rotates, which drives the rotating rod 44 to rotate. When the rotating rod 44 rotates, it can drive the cam 47 to rotate. When the cam 47 rotates, the entire lifting seat 45 moves up and down because it contacts the inner wall of the through hole 46. When the lifting seat 45 moves up and down, it can drive the fixed seat 51 to move up and down. When the fixed seat 51 moves up and down, it will finally drive the two clamping plates 31 to slide back and forth continuously through the first adjusting rod 54 and the second adjusting rod 57. When the fixed seat 51 moves up and down, it can drive the first adjusting rod 54 and the second adjusting rod 57 to move. The bottom ends of the first adjusting rod 54 and the second adjusting rod 57 will drive the two clamping plates 31 to move periodically during the movement, that is, the two clamping plates 31 approach or move away from each other periodically. When the two clamping plates 31 approach each other, they will contact the spherical plain bearings being transported on the conveyor belt 23, thereby pushing all the spherical plain bearings to the middle position on the conveyor belt 23. In this way, after all the spherical plain bearings pass through a certain distance on the conveyor belt 23, they will be in an orderly conveying state. At this time, it is convenient for the subsequent processing machinery to position and grab the spherical plain bearings through the manipulator, thus facilitating the subsequent process.

[0033] Specifically, the auxiliary structure 6 includes a connecting rod 61, a sliding sleeve 62, a fixed rod 63, a rubber sleeve 64, a bottom rod 65 and a limiting hole 66. The side of the lifting seat 45 facing away from the fixed seat 51 is fixedly connected with the connecting rod 61, the supporting seat 41 is provided with the limiting hole 66, the connecting rod 61 passes through the limiting hole 66 and the connecting rod 61 is slidably connected to the limiting hole 66, the bottom end of the feeding hopper 22 is slidably connected with the sliding sleeve 62, the bottom of the sliding sleeve 62 is fixedly connected with the bottom rod 65, the fixing rod 63 is fixedly connected to the bottom rod 65, and the fixing rod 63 is fixedly connected to the rubber sleeve 64. After the motor 42 is energized and turned on, the lifting seat 45 can be moved up and down eventually, and while the lifting seat 45 moves up and down, the Because the connecting rod 61 is connected to the lifting seat 45, when the lifting seat 45 moves up and down, the connecting rod 61 will also move up and down. When the connecting rod 61 moves up and down, it will drive the sliding sleeve 62 to move accordingly, and then the fixing rod 63 and the rubber sleeve 64 will move up and down. Therefore, the joint bearing originally placed in the feeding hopper 22 will be poured out from the gap between the sliding sleeve 62 and the conveyor belt 23 little by little as the sliding sleeve 62 moves up and down, and then be conveyed by the conveyor belt 23. The setting and continuous movement of the sliding sleeve 62 ensure that when a large number of joint bearings are poured into the feeding hopper 22, they will not be stuck. As long as the sliding sleeve 62 keeps moving all the time, thereby causing the fixing rod 63 and the rubber sleeve 64 to keep moving, it can be ensured that the joint bearing in the feeding hopper 22 will not block the feeding hopper 22.

[0034] When the present invention is in use, first, the spherical plain bearing to be used can be placed into the feeding hopper 22 on the connecting seat 21. The bearings in the feeding hopper 22 will continuously be placed onto the conveyor belt 23, and the conveying task of the spherical plain bearing is completed through the conveyor belt 23. When the conveyor belt 23 conveys one spherical plain bearing after another, the two clamping plates 31 will periodically move closer to and away from each other. Therefore, with the continuous movement of the two clamping plates 31, finally the spherical plain bearing will be pushed to the middle position of the conveyor belt 23. The four sliders 33 slide in the four chutes 34, increasing the distance that the two clamping plates 31 can move. Moreover, rubber pads 32 are fixedly connected to both of the two clamping plates 31, which can prevent the two clamping plates 31 from being deformed by extrusion with the spherical plain bearing during movement. After electrically connecting the motor 42 to an external power source, the motor 42 can be started. After the motor 42 is started, its output shaft rotates, driving the rotating rod 44 to rotate. The rotation of the rotating rod 44 can drive the cam 47 to rotate. When the cam 47 rotates, it will cause the entire lifting seat 45 to move up and down because it contacts the inner wall of the through hole 46. The up and down movement of the lifting seat 45 can drive the fixed seat 51 to move up and down. When the fixed seat 51 moves up and down, it will finally drive the two clamping plates 31 to slide back and forth continuously through the first adjusting rod 54 and the second adjusting rod 57. When the fixed seat 51 moves up and down, it can drive the first adjusting rod 54 and the second adjusting rod 57 to move. The bottom ends of the first adjusting rod 54 and the second adjusting rod 57 will drive the two clamping plates 31 to move periodically during the movement, that is, the two clamping plates 31 will periodically move closer to or away from each other. When the two clamping plates 31 move closer to each other, they will contact the spherical plain bearing being transported on the conveyor belt 23, thereby pushing all the spherical plain bearings to the middle position on the conveyor belt 23. In this way, after all the spherical plain bearings pass through a certain distance on the conveyor belt 23, they will be in an orderly conveying state. At this time, it is convenient for the subsequent processing machinery to position and grasp the spherical plain bearings through the manipulator, thus facilitating the subsequent process. After the motor 42 is powered on and started, finally the lifting seat 45 can move up and down. While the lifting seat 45 moves up and down, since the connecting rod 61 is connected to the lifting seat 45, when the lifting seat 45 moves up and down, the connecting rod 61 will also move up and down. When the connecting rod 61 moves up and down, it will drive the sliding sleeve 62 to move accordingly, and further cause the fixed rod 63 and the rubber sleeve 64 to move up and down. Therefore, the spherical plain bearings originally placed in the feeding hopper 22 will be poured out little by little from the gap between the sliding sleeve 62 and the conveyor belt 23 as the sliding sleeve 62 moves up and down, and thus be conveyed by the conveyor belt 23. The setting and continuous movement of the sliding sleeve 62 make it so that when a large number of spherical plain bearings are poured into the feeding hopper 22, they will not be exactly in a stuck state. As long as the sliding sleeve 62 always keeps moving, and further causes the fixed rod 63 and the rubber sleeve 64 to keep moving, it can ensure that the spherical plain bearings in the feeding hopper 22 will not block the feeding hopper 22.
