T-bolt processing, we use the traditional method is to first use the four-jaw chuck to find the flat head center hole of the T-bolt, and then use the shaft hole center to hold the flat head center hole to hold the card to play the other end of the center hole, and use the tail center to hold the T-bolt with the four claws to find the right to hold the flat head to process the outer circle and screw thread, this method is time-consuming and laborious, seriously affecting the production efficiency.

Second, the solution
1. Can the traditional method of making center holes at both ends be replaced with a simple and efficient method? After various attempts, I processed an auxiliary sleeve with the largest diagonal Angle of T-bolt as the inner diameter, milling a 20mm gap to form a tightening sleeve, which solved the problem of finding the center hole at both ends, and could improve production efficiency.
2, the specific practice is to process a blind hole sleeve according to the maximum diagonal diameter of the T-bolt, weld two pads in the hole, and weld the pads into a certain Angle, so that the flat head of the T-bolt can be well clamped with three claws to find the right.
T-bolt
T-bolt into the fetal tool with three claws to find the center hole, and then with the center top tight can be processed and threaded machining.
3. Benefit calculation
1, processing 1 M36*540 T-bolt, with the original method takes 45 minutes; It only takes 25 minutes with the new method.
2, 1 year spare parts processing about 400 such bolts, a year to save 8000 minutes, the annual saving time cost of about 133 hours *30 yuan/hour =3990 yuan.
T-bolt
The bolt is a tool that can be used with the nut to a certain extent, and it has a very important purpose, not only can be used as a connection button for some pipes, but also can play an important role in the installation and connection of some instruments. T-bolt is a device that can be used to join some nuts, and it has extremely important applications in industry. Let's take a look at some of the applications of T-bolts and some of their standards.
T-bolt
T-bolts (GB/T37-1988) are generally used on nuts matching T-slots. General surface treatment: galvanized or nickel-plated or black. Product use: T-bolt, European standard called hammer bolt, material for carbon steel and stainless steel.
Standard for T-bolt :
T-bolts, bolts, nuts GB/T2165-1991 Machine tool fixture parts and components, T-slot quick release bolts (obsolete), adjusted to JB/T8007.2-1995, replaced by JB/T8007.2-1999 machine tool fixture parts and parts, T-slot quick release bolts. GB/T37-1988T bolts, with mechanical standards :JB/T1709-1991T bolts (obsolete), replaced by JB/T1700-2008 valve parts, nuts, bolts and plugs. At present, the commonly used DIN186T square neck bolts, national standard GB37,DIN188T double neck bolts, materials are carbon steel, stainless steel, alloy steel, etc., specifications from M8-M64, quality control is better domestic quality hardware production - Mu Sheng, has formed a mature process.
T-bolt
T-bolt can be widely used in some industrial production and mechanical processing production, it is widely used in our lives. The material of the T-bolt has a lot of differences, and correspondingly, the bolts of different materials are used in different scenes and different positions.
