Description

Technical Field

[0001] The invention relates to the technical field of bearing assembly, and in particular to a bearing ring cleaning and conveying device for bearing production. Background Art

[0002] When bearings are manufactured, each component is first produced separately and then assembled into bearings. After production, the bearing rings are generally coated with anti-rust oil and stored in the warehouse. The purpose of applying anti-rust oil is to avoid rust during storage.

[0003] In the existing bearing ring cleaning device, when ultrasonically cleaning the bearing ring, the bearing ring material is generally poured onto a mesh plate, the mesh plate and the material are immersed in a cleaning tank for cleaning, and finally the mesh plate is lifted up to pour out the material for the next batch of cleaning. This makes it troublesome to load and unload the bearing ring when cleaning, and the cleaned bearing rings are piled together. When the bearing rings are taken for use in the next process, the material needs to be rearranged, which is inconvenient. Summary of the invention

The bearing ring parts are poured into the material placement chamber 110, and the vibration motor 121 is started, thereby driving the vibration plate 120 to vibrate, and the vibration plate 120 drives the bearing ring material thereon to vibrate, so that the material on the vibration plate 120 is in constant motion, which is convenient for the movement of the material. A reducing rod 311 is fixedly connected to one end of the first spiral portion 310, and the spiral radius of the reducing rod 311 gradually increases from one end close to the first spiral portion 310 to the other end, so that the other end of the reducing rod 311 can pass through the material pile, and at the same time reduce the contact between the first spiral portion 310 and the material pile, thereby reducing the resistance of the first spiral portion 310 to the transported bearing ring, which is convenient for the transmission of the bearing ring.

[0033] The top surface of the vibration plate 120 is concave and cambered, and the heights of the two ends of the top surface of the vibration plate 120 are higher than the height of the top surface of the vibration plate 120 located below the reducer 311. Combined with the vibration of the vibration plate 120, it is convenient for the material to gather below the reducer 311, thereby facilitating the reducer 311 to wear the bearing ring. The fixed frame 3 800 includes two support rods 2 810, and the arc-shaped outer side walls of the two support rods 2 810 are fixedly connected to the top surface of the material storage box 100. Three roller rods 3 820 are connected in a circular equiangular rotation between the two support rods 2 810, and the three roller rods 3 820 surround and support the first spiral portion 310. The length of the roller rod 3 820 is less than the length of the first spiral portion 310, and the first spiral portion 310 is supported by the fixed frame 3 800.

The unloading screw rod 600 is limited by the three roller rods 420, and the unloading screw rod 600 is driven to rotate by the motor 440. Although the bearing The bearing ring is on the unloading screw rod 600 and cannot slide directly to the bottom end of the unloading screw rod 600 due to the obstruction of the roller rod 420. However, the motor 440 drives the unloading screw rod 600 to rotate through the roller rod 420 to realize the downward transportation of the bearing ring. The bottom end of the unloading screw rod 600 is detachably connected to the limiting round table 610, so that the bearing ring falls horizontally downward when it slides. The limiting round table 610 with different outer diameters can be replaced according to the inner diameter of the bearing ring.

[0034] Working principle: When in use, the bearing ring parts are poured into the material placement chamber 110, and the vibration motor 121 is started, thereby driving the vibration plate 120 to vibrate, and the vibration plate 120 drives the bearing ring material thereon to vibrate, and the motor 2 731 drives the corresponding roller rod 2 720 to rotate through the belt and the pulley 733, and the roller rod 2 720 drives the second spiral part 330 to rotate, so that the transmission spiral rod 300 rotates, and the diameter reducing rod 311 rotates, and when the other end of the diameter reducing rod 311 passes through the material pile, a number of bearing rings will be worn on the diameter reducing rod 311, and due to the rotation of the diameter reducing rod 311 Due to the movement and the deadweight of the bearing ring, the bearing ring slides onto the first spiral portion 310, and the bearing hung at the bottom of the first spiral portion 310 is transported rightward to the first transition portion 320 through the rotation of the first spiral portion 310. The rear bearing ring squeezes the front bearing ring, so that the bearing ring moves rightward on the first transition portion 320, and the bearing ring enters the second spiral portion 330 and slides to the bottom end of the second spiral portion 330, so that the bearing ring is immersed in the cleaning liquid in the cleaning tank 210. The rotation of the second spiral portion 330 drives the bearing ring to move rightward in the cleaning tank 210, thereby cleaning the bearing ring.

[0035] As the second spiral portion 330 rotates, the cleaned bearing ring is moved to the second transition portion 340, and the bearing ring that subsequently enters the second transition portion 340 is squeezed, thereby pushing the front bearing ring through the arc-shaped connecting rod 500 and into the unloading screw rod 600. Although the bearing ring cannot slide directly to the bottom end of the unloading screw rod 600 due to the obstruction of the roller rod 1 420 on the unloading screw rod 600, the motor 1 440 drives the unloading screw rod 600 to rotate through the roller rod 1 420, so as to realize the downward conveyance of the bearing ring until the bearing ring moves to the bottom of the roller rod 1 420, and the bearing ring falls from the limiting truncated table 610 under the action of gravity, so as to realize the cleaning and transportation of the bearing ring, and realize the sorting and arrangement of the bearing ring, without the need to manually adjust the posture of the bearing ring, which is convenient for the next process and does not require manual loading.

[0036] By setting the transmission screw rod 300, the arc-shaped connecting rod 500 and the unloading screw rod 600, the unloading screw rod 600 limits the left movement of the transmission screw rod 300 during rotation through the arc-shaped connecting rod 500, and at the same time, the transmission screw rod 300 limits the downward movement of the unloading screw rod 600 through the arc-shaped connecting rod 500, so that the transmission screw rod 300 and the unloading screw rod 600 both keep rotating in place, thereby realizing the limitation of the unloading screw rod 600 and the transmission screw rod 300.
