Problems solved by technology

[0004] The annual demand for E-bolts of various specifications and models is very large. Due to its special shape, it is very difficult to process. The traditional processing method is a single cylindrical turning method. The manufacturing process is as follows: Clamp the E-bolt on the chuck , adjust the center of a cylinder of the E-bolt to be consistent with the center of the spindle, and then clamp the E-bolt. At the same time, use a special top to withstand the end face of the stud, start the machine tool to rotate, and the tool feed car to form the outer circle of a cylinder; press the above Step two more clamping can complete the turning of the second and third cylindrical outer circles. The traditional processing method is single stud turning. There is no reliable processing and positioning means. There are many human factors, low dimensional accuracy, and position tolerance is not easy to guarantee. Moreover, one E-bolt needs to be clamped three times, and the auxiliary clamping and tool sharpening time is long, the labor intensity is high, and the production efficiency is low.

Embodiment Construction

[0023] A novel method for processing E-bolts is characterized in that it comprises the following steps:

[0024] a. Processing and installation of special tires: first install the special processing tires on the middle carriage of the C6140 ordinary lathe, use inserts and bolts at the dovetail groove to fix the special processing tires and the middle carriage of the lathe together, and adjust Pad adjustment center height is consistent with the center height of the machine tool;

[0025] b. Turning outer circle and chamfering: first install the clamping tool of the sleeve type combined machine on the lathe chuck, place the E-bolt to be processed on the movable pressure plate of the special processing mold, lift the clamping pressure plate and pass it on the moving guide rail Use the swivel bolts to fix the E-bolts on the movable platen. Use a tool to tap and adjust the stud position of the E-bolts to make the center of the E-bolts match the center of the tool. The linear movem...

Abstract

The invention relates to a method of screw bolts used in processing a scraper chain, in particular to a novel method of processing E-type screw bolts. The method includes the following steps: processing and installing dedicated clamping fixture, truning, chamfer and threading; the inventive method is simple and unique, and has high dimensional accuracy, easily guaranteed positional tolerance, short time of auxiliary fixing and tool sharpening, low labor intensity and high production efficiency.

Description

technical field [0001] The invention relates to a method for processing bolts used in scraper chains, in particular to a novel method for processing E-shaped bolts. Background technique [0002] The scraper chain is one of the important parts in the scraper conveyor. The scraper chain is mainly connected and fastened together with the connecting bolts, and the scraper chain is driven by the power unit to run continuously to complete the task of underground coal transportation. . If the connecting bolts are unreliable, it is easy to drag the scraper and the chain apart, resulting in the loss of the scraper, which greatly affects the efficiency of the scraper conveyor for conveying coal. In order to avoid this problem, it is necessary to design and manufacture a reliable connection method to meet the continuous coal transportation requirements of the scraper conveyor. [0003] In order to ensure that the scraper chain has a reliable connection structure and meet the high-yie...
