Embodiment 1

[0048] Example 1, such as Figure 2 to Figure 4 As shown, the application of the spindle locking device on the tire uniformity / eccentricity testing machine mainly includes:

[0049] The upper rim shaft 1 and the lower rim shaft 2 that can be mated vertically;

[0050]The lower rim shaft 2 is installed on the base 13, and the upper rim shaft 1 is connected and driven by the cylinder 14;

[0051] Through the columns 15 and linear guide rails 16 on both sides, the upper rim shaft 1 is driven by the cylinder 14 to move vertically;

[0052] A positioning groove 3 is provided in the inner cavity of the upper rim shaft 1, and six clamping blocks 4 are sheathed on the lower rim shaft 2, and each clamping block 4 is respectively connected to a set inside the lower rim shaft 2, with 6 uniformly distributed The trapezoidal block 7 of the T-shaped groove, the trapezoidal block 7 is assembled on a piston 8 that can reciprocate axially along the lower rim shaft 2;

[0053] In the lower r...

Abstract

The invention relates to a main shaft locking device and method. A mechanical execution mechanism for driving radial locking through axial displacement is adopted and axially braked in the radial locking process to improve the locking arrival rate and the location accuracy between an upper rim shaft and a lower rim shaft, locking failures caused by the facts that associated pneumatic components are failed or an air source is accidentally closed are accordingly avoided, and the safety of device use and operators is accordingly and effectively protected. The main shaft locking device comprises a butt joint part between the upper rim shaft and the lower rim shaft, a locating groove with the concave circumference and a plurality of clamping blocks capable of being inserted into or retreated from the locating groove in the radial direction, the clamping blocks are connected to a driving mechanism, the driving mechanism drives the clamping blocks to perform reciprocating motion in the radial direction, is arranged in an inner cavity of the upper rim shaft or the lower rim shaft and performs axial motion, an annunciator is installed on the driving mechanism, and a detector for sensing the axial motion position of the annunciator to judge the radial positions where the clamping blocks are located is installed on the upper rim shaft or the lower rim shaft where the driving mechanism is installed.

Description

technical field [0001] The invention relates to a spindle locking device applied to tire testing machines (such as dynamic balance, uniformity / eccentricity testing machines, etc.) and a locking and detection method thereof, which belong to the field of rubber machinery and industrial automation. Background technique [0002] In the process of manufacturing rubber tires, a series of testing items need to be carried out online, such as dynamic balance and uniformity / eccentricity testing before the tires leave the factory, so as to test and rate related items during the tire manufacturing process . [0003] For example, on the uniformity / eccentricity testing machine, it is a special equipment for automatic online detection of the uniformity, size deviation and unevenness of all-steel truck tires. Usually, the tire to be tested needs to be clamped between the upper and lower rims. At this time, the upper rim shaft and the lower rim shaft are docked and locked, and then inflated...
