What is the tolerance range of precision screws?
T-bolts have been widely used in the fields of aviation, aerospace and defense due to their good positioning and anti-shedding effects. Its related standards have special requirements for accurate positioning, anti-falling off, and dimensional consistency of T-bolts. This requires that the position, size and shape and position tolerance of the anti-fall hole of the T-bolt shank must be controlled within a certain range. Therefore, the processing method of the anti-shedding hole is particularly important. Since the machined anti-shedding hole is located at the position of the rod, the milling processing efficiency is too low, the product cost is high, and there is a large machining error. When conventional drilling is used, the consistency of the anti-shedding hole size cannot be guaranteed. To solve the above problems of low efficiency and dimensional instability
Guangdong Yueluo Hardware Industry Co., Ltd. has a simple structure, low processing difficulty, and convenient riveting. The whole pin has the same diameter except for the annular groove. The drawn wire can be directly used, which saves the cost of materials and machining costs, and improves the production speed and efficiency. The structure does not require high machining accuracy of the hole, which can effectively reduce the machining cost and the rework rate of the parts.
screw grooving device comprises a workbench, a vibrating plate is arranged on the upper part of the workbench, a conveying device is arranged below a discharge port of the vibrating disc, the slotting device is arranged on one side of the conveying device, and the slotting device is provided with a reciprocating device. When the movement is extended, the cutting wheel can be used for grooving the screws in the conveying device, and the grooving device is also fixedly provided with a fixed wheel for grinding the grooved screws.
In order to solve this technical problem, Yueluo Company provides an adjusting nut, which includes a bearing unit, a thrust washer, an adjusting nut and a snap ring. The inside of the adjusting nut is an internal thread structure, and one end of the internal thread structure is provided with Ring groove, the snap ring is pressed into the ring groove with interference, and is rigidly connected with the adjusting nut without relative movement; the bearing unit is supported on the shaft, and the thrust washer is in plane fit with the bearing unit; the adjusting nut and the shaft are threadedly connected , Fit with the thrust washer plane, the inner diameter of the snap ring and the thread of the shaft are in interference fit.
