Description

Technical Field

[0001] The invention relates to the technical field of tire wear measurement, and in particular to a tire wear measurement stand and a use method thereof. Background Art

[0002] The main method of measuring tire wear is to use a tread depth gauge to measure the depth of the tire tread. When measuring, place the measuring surface of the depth gauge perpendicular to the circumferential groove of the tire, close to the tire tread, and then extend the tip of the gauge tongue into the bottom of the main tread groove of the tire tread to read the depth value. Usually, the tread depth of a new tire is generally between 8 and 10 mm.

[0003] Referring to the patent document with application number "CN201810306221.X" and titled "A Tire Wear Measuring Stand", this patent document arranges each probe side by side in a sliding groove of the probe box to facilitate adjustment of the lateral position distribution of each probe on the tire tread; and by arranging a linear elastic component connected to the needle rod inside the needle seat, the needle rod generates different forces according to changes in the tire tread contacted by the needle end contact piece.

An auxiliary groove is provided on the hanging buckle (102), and a hand-pushing slider (104) is provided on the auxiliary groove, and the hand-pushing slider (104) is fixedly connected to one end of the telescopic rope (103) via an auxiliary rod; The driving machine (10) is provided with a driving end (105), and a probe (106) is fixedly connected to the driving end (105) via a fastener, and the probe (106) is adapted to the tread pattern.

10. A method for using a tire wear measuring stand, using the tire wear measuring stand according to any one of claims 1 to 9, characterized in that: The method of use comprises the following steps: Step S1. Place the tire to be tested on the support rod (2), adjust the angle of the support rod (2) to suit the specifications and size of the tire, start the electric drive to make the rotating shaft (3) rotate in both directions, thereby controlling the support rod (2) to open and close at a limited angle, transmit the electric drive to the driving plate (51) through the driving rod (5), so that the tire (4) produces a small rotation effect, thereby improving the measurement effect of the probe (106) on the tread, adjust the first stud (52) to control the steering of the driving rod (5), and at the same time adjust the second stud (62) on the mounting shaft (61) to transmit the adjustment force and the acting force; Step S2. The third stud (64) is rotated by the knob (63) to horizontally set the force of the second stud (62), and the fourth stud (65) is adapted to the bottom of the first stud (52). Through holes are opened at both ends of the driving rod (5), and threaded rings are installed and fixed to the through holes by fasteners. A semicircular frame (7) is provided at the bottom of the column (1) to limit the correct opening and closing of the support rod (2) and correct its position. The support rod (2) slides in the slide groove (72) through the connecting rod (8) to achieve the stability of the support rod (2). A data screen (9) is provided on the column (1) to observe the data measured by the driving machine (10). The driving machine (10) is provided on the support rod (2). The state and wear of the tread of the tire (4) are assisted by the probe (106); S3. The driving machine (10) is provided with a storage battery as a power source and is fixed to the support rod (2) via a hanging rod (101). The hanging rod (101) is provided with a telescopic connecting rod and a telescopic rope (103) for improving the connection strength between the end of the hanging rod (101) and the driving machine (10). The hanging buckle (102) is provided with an auxiliary groove for the sliding groove of the hand-pushing slider (104) to achieve the length adjustment and fixation of the telescopic rope (103). The driving machine (10) is provided with a driving end (105). The probe (106) is fixedly connected to the driving end (105) via a fastener, so as to facilitate the subsequent disassembly and maintenance.
