Description

Technical Field

[0001] The invention relates to the technical field of steel ball cleaning, in particular to a multi-stage steel ball cleaning production line. Background Art

[0002] Steel balls, also known as steel beads, are divided into grinding steel balls, forging steel balls, and casting steel balls according to the production and processing technology, and are divided into bearing steel balls, stainless steel balls, carbon steel balls, copper bearing steel balls, alloy steel balls, etc. according to the processing materials. Among them, bearing steel balls are the core component of bearings. They reduce the friction inside the bearings through rolling friction. The design of bearing steel balls enables bearings to efficiently transmit mechanical power and improve the efficiency of mechanical devices.

[0003] In the production process of bearing steel balls, the rough-ground steel balls need to be quenched before entering the "hard grinding" process. Currently, quenching mainly uses quenching oil to cool down. The surface of the steel balls after quenching usually absorbs quenching oil. Before entering the "hard grinding" process, the quenching oil on the surface of the steel balls must be cleared.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and functions achieved by the present invention clearer and easier to understand, the present invention is further explained below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figure 1 As shown, the present invention proposes a multi-stage steel ball cleaning production line, including a plurality of ultrasonic cleaning pools 1, steel ball boxes 26, a box shifting mechanism 382, ​​and a recovery device arranged in sequence. In this embodiment, the number of ultrasonic cleaning pools 1 is three, the steel ball boxes 26 are used to load steel balls and place them into the ultrasonic cleaning pools 1 for cleaning, and the box shifting mechanism 382 is used to place the steel ball boxes 26 containing steel balls into three ultrasonic cleaning pools 1 in sequence.

[0022] like Figure 2 As shown, a cleaning chamber 3 is provided on the top surface of the ultrasonic cleaning tank 1, and an upper groove 4 and a lower through hole 5 are provided on the bottom wall of the cleaning chamber 3 in sequence. The cross section of the upper groove 4 is circular, the cross section of the lower through hole 5 is circular, and the diameter of the upper groove 4 is larger than the aperture of the lower through hole 5.

[0023] The working principle of the ultrasonic cleaning pool 1 is to use a transducer to convert the sound energy of the high-power ultrasonic frequency source into mechanical vibration, so that the cleaning liquid in the cleaning chamber 3 is radiated to the ultrasonic wave. Due to the radiated ultrasonic wave, the microbubbles in the cleaning liquid in the cleaning chamber 3 can maintain vibration under the action of the sound wave. When the sound pressure or sound intensity reaches a certain level, the bubbles will expand rapidly and then suddenly close. During this process, a shock wave is generated at the moment of bubble closure, which generates a pressure of 1012-1013pa around the bubble and local temperature regulation. The huge pressure generated by this ultrasonic cavitation can destroy insoluble dirt and differentiate them in the cleaning liquid. The specific structure of the ultrasonic cleaning pool 1 emitting ultrasonic waves is a prior art and will not be described in detail here.

At this time, the cleaning liquid and quenching oil can pass through the liquid inlet hole 11, the liquid chamber 10, and the liquid outlet hole 12 in sequence.

[0033] When the liquid discharge controller 6 is closed, the piston rod of the driving electric cylinder 25 extends, thereby pushing the stabilizing ball upright 17, the closing ball 16, and the liquid isolation sealing plate 18 upward, and the closing ball 16 abuts against the lower hole edge of the liquid inlet hole 11 to limit the passage of cleaning liquid and quenching oil.

The length direction of the top plate 40 is consistent with the width direction of the tunnel oven. The top plate 40 spans the tunnel oven and the return conveyor. A top hole 41 is opened through the top surface of the top plate 40. The cross section of the top hole 41 is a long strip.

The cross section of the stabilizing cross bar 45 is circular, and the length direction of the stabilizing cross bar 45 is the same as the length direction of the top plate 40.

[0044] like Figure 5 and 6 As shown, a stabilizing transverse hole 46 with a circular cross section is opened through the side wall of the transverse displacement cylinder seat 42. There are two stabilizing transverse holes 46, which are symmetrical to each other. The two stabilizing transverse holes 46 are respectively used for two stabilizing transverse rods 45 to pass through. The stabilizing transverse holes 46 and the stabilizing transverse rods 45 are slidably matched, so that the transverse displacement cylinder seat 42 can slide laterally above the top plate 40 more stably.

[0045] like Figure 5 and 6 As shown, the vertical drive cylinder 47 is fixedly installed on the top surface of the transverse cylinder base 42. The piston rod of the vertical drive cylinder 47 passes through the transverse cylinder base 42 and the top hole 41 in sequence and is connected to the hook box device 48. The vertical drive cylinder 47 is used to drive the hook box device 48 to perform up and down reciprocating linear motion.

[0046] When the box moving mechanism 382 is working, the horizontal drive cylinder 43 drives the horizontal drive cylinder seat 42 to move back and forth along the length direction of the top plate 40, and the vertical drive cylinder 47 can drive the box hook device 48 to move up and down, and the driving component can drive the box hook device 48 to move up and down and laterally.

[0047] like Figure 6 and 7 As shown, the box hook device 48 includes a box hook insertion column 49 and a box hook frame 59.

When the external force pushes the top guide plate 56, the vertical shaft 53, and the bottom guide plate 57 to move downward, the return spring 58 is stressed and then changes to a compressed state. Since the hinge point of the linkage rod 55 and the hinge frame 54 is higher than the hinge point of the linkage rod 55 and the hook box clip 52, the linkage rod 55 will push the hook box clip 52 to slide out of the hook box guide hole 51. When the external force is withdrawn, the return spring 58 resets to push the bottom guide plate 57, the vertical shaft 53, and the top guide plate 56 to move upward, and the linkage rod 55 will pull the hook box clip 52 to slide into the hook box guide hole 51.

The hook box cylinder 60 is fixedly installed on the inner wall of the hook box frame 59 facing the hook box plug column 49, and the hook box cylinder 60 is located directly above the shaft top guide plate 56. When the piston rod of the hook box cylinder 60 is extended, the piston rod of the hook box cylinder 60 will push the shaft top guide plate 56, the vertical shaft 53 and the shaft bottom guide plate 57 to move downward. Since the hinge point of the connecting rod 55 and the articulated frame 54 is higher than the hinge point of the connecting rod 55 and the hook box clip 52, the connecting rod 55 will push the hook box clip 52 to slide out of the hook box guide hole 51.

[0053] This multi-stage steel ball cleaning production line can automatically perform three-stage ultrasonic cleaning on steel balls, with good oil removal effect.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
