Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 4, the pair of wheels 900 of this embodiment includes a rim 910, and the two pairs of wheels 900 are coaxially mounted on a pair of wheel shafts 920, respectively.

Example one

Referring to fig. 1-15, the train wheel circle run-out detection device of the embodiment includes a detection device, the detection device includes a detection block 710, the detection block 710 is installed on one end of a lubrication housing 720, the other end of the lubrication housing 720 is inserted into an insertion groove 731, the insertion groove 731 is arranged on an insertion seat 730, the insertion seat 730 is assembled with one end of a sliding shaft 780, the other end of the sliding shaft 780 is installed into a sliding tube hole 791, and a sliding ring 781 is installed on the end, the sliding ring 781 and the sliding tube hole 791 are assembled in a circumferential rotation and axial sliding manner, the sliding tube hole 791 is arranged in a sliding tube 790, the sliding tube 790 is installed into a threaded sleeve 702 and assembled with the threaded sleeve 702 in a screwing manner, the threaded sleeve 702 is installed on the detection plate 630, a detection frame 632 is installed on the detection plate 630, a linear potentiometer 450 is installed on the detection frame 631, a detection shaft 451 of the linear potentiometer 450 is assembled with one end of the detection shaft 701, the other end of the detection shaft 701 is assembled with the sliding shaft 780, therefore, when the sliding shaft 780 moves axially, the detection shaft 701 and the detection shaft 451 can be driven to move synchronously, so that the linear potentiometer 450 obtains a signal, and the signal is input into the industrial personal computer by the linear potentiometer.

The portion of the slide shaft 780 between the bottom end surface of the slide tube 790 and the socket 730 is sleeved with a detection spring 810, and the detection spring 810 is used for applying an elastic force to the socket 730 to push the detection block 710, so that the detection block 710 is kept pressed on the side surface of the rim 910.

When the wheel rim is used, the detection block 710 and the wheel rim 910 only need to rotate relatively, and the detection block 710 slides for one circle along the circumference of the wheel rim 910. In the process, if circular runout exists on the side wall of the rim 910, the detection block 710 is enabled to displace in the radial direction of the rim 910, the displacement directly drives the linear potentiometer 450 to generate signal change, so that the runout displacement (runout) can be calculated through the signal change, finally, whether the circular runout of the rim 910 is qualified or not can be judged by comparing the displacement with a runout interval, and if unqualified parts exist, the circular runout can be manually or mechanically marked, so that subsequent repair and replacement are facilitated. This design utilizes a small area of contact of the sensing mass 710 with the rim 910 and therefore is more sensitive to the perception of circular runout, similar to the manner of thimble-type circular runout sensing. In addition, the detection block 710 and the linear potentiometer are in a relative static state when no external force acts, and almost no assembly tolerance exists in the axial direction of the detection shaft, so the detection precision is more accurate.

Preferably, in order to protect the linear potentiometer 450, a protective cover 631 is further mounted on the mounting plate 630, and the protective cover 631 covers the linear potentiometer 450 and the detection frame 632.

Preferably, the first bolt 301 passes through the socket 730 and presses against the outer wall of the lubricating housing 720, so that the lubricating housing 720 and the socket 730 are relatively fixed.

Preferably, since the detecting block 710 slides in a pressing manner with the side wall of the rim 910, there is a certain friction force, and this friction may cause the abrasion of the detecting block and the rim 910, and the friction of the detecting block generates heat, which causes thermal deformation, and affects the final detection accuracy. For the inventor, a lubricating cavity 722 is arranged in the lubricating shell 720, and a penetrating oil hole 721 is arranged at one end of the lubricating shell 720 close to the detection block 710, and the oil hole 721 is communicated with the lubricating cavity 722; a sponge block 740, a gate valve block 760 and an oil box 750 are sequentially arranged in the lubricating cavity 722 from bottom to top, a hollow oil box cavity 751 is arranged in the oil box 750, the top of the oil box cavity 751 is opened, and the opening is sealed by an oil box top cover 752; the oil box cavity 751 is filled with lubricating oil, the bottom of the oil box cavity 751 is assembled with one end of an oil guiding block 741, the other end of the oil guiding block 741 passes through a gate valve block 760 and then is connected with a sponge block 740, and the oil guiding block 741 is made of a high oil absorption material, such as oil absorption sponge. The design can lead the lubricating oil in the oil box cavity 751 to be slowly drained to the sponge block 740 through the oil guiding block 741, the sponge block 740 can overflow the lubricating oil after oil absorption saturation, so that the lubricating oil gradually penetrates out of the oil hole 721 and flows along the outer wall of the detection block 710, the contact part of the detection block 710 and the rim 910 is finally lubricated, the flowing of the lubricating oil can also play a role in heat dissipation and temperature reduction on the detection block 710, and the lubricating oil only flows out in a small amount in this way, so that the lubricating oil is saved.

When the oil guide block is used, the extrusion table 772 can be driven to move close to or away from the oil guide block 741 only by rotating the second bolt 302. When the detection block slides, the extrusion table 772 incompletely presses the oil guide block 741, so that the lubricating oil can penetrate through the oil guide block 741 to enter the sponge block 740, and then the detection block is lubricated. When the oil guide block 741 is not used, the oil guide block 741 is directly pressed against the auxiliary plate 762 by the pressing table 772, so that the oil guide block 741 cannot continue to pass through or the lubricating oil is difficult to pass through, and the lubricating oil can be prevented from continuously seeping out, and the waste of the lubricating oil is avoided. The leakage amount of the lubricating oil can be adjusted by adjusting the extrusion pressure of the extrusion table 772 on the oil guide block 741, so that the flow rate of the lubricating oil in the oil holes can be flexibly adjusted according to needs.
