New algorithm for expanding the dimensions of curved parts

The calculation method introduced in this paper is simple and practical, and can guarantee the dimensional accuracy of the general curved parts, especially in the case where the bending radius can only be guaranteed by the mold. The calculation formula is: Expansion length = sum of lengths in .......

Multi-functional drilling fixture

There are many kinds of tools for processing discs and couplings in our factory. In the past, we used drilling to drill uniform holes, which is low in efficiency and labor intensive. To this end, we installed a multi-power clip county on a TZ32 type drilling head combination machine, which was.......

Processing of large diameter thin wall eccentric sleeve

We process hard aluminum (LY12) eccentric workpieces, the thinnest part is only 2.05mm. The eccentric clamp can control the deformation amount within 0.02mm, and ensure the other precision requirements of the drawing. The workpiece is positioned with φ150mm hole, and the inner hole step is.......

After the metal ring is heated, the inner hole increases or decreases

After the metal ring (cylinder) is heated, does the inner hole increase or decrease? What does it have to do with the size of the ring (tube)? When I was in middle school, there was a problem of thermal expansion and contraction on the physical test paper. The idea is that after the metal ring.......

Rail processing fixture

The guide rail of the structure shown in Figure 1 is widely used, but it is difficult to process. The upper rail 5 and the lower rail 4 have an angular error of ±0.30", the verticality is less than 0.01 mm, the lower rail 4 is 500 mm long, the material is 40Cr steel, and the surface is.......

Machining mechanism and tool technology for high speed cutting

I. Introduction High-speed cutting technology has become an important part of advanced manufacturing technology for the 21st century with its unique principle advantages and huge potential application value. It is also one of the hot areas of current research in the scientific and industrial c.......

High precision measurement of verticality error

In the trial production process of a new product, we encountered a measurement problem with high verticality error requirements. The main part of the product has a verticality error of 0.008 mm on the adjacent sides of the product, which is to ensure that the part reaches this technology. It i.......

Floating reaming of quenched and tempered steel

I. The problem is raised. The top column of the 2105 diesel engine oil pump (Fig. 1) is a quenched and tempered steel piece with partial quenching. The workpiece φ10_0~(+0.022)mm transverse hole is machined to φ94_0~(+0.10)mm before heat treatment, and is subjected to floating reaming .......

Molding the taper by the method

In the past, when we processed the tapered hole, we first expanded it on the T68 trampoline, and then made a manual hinge. Due to the large diameter of the tapered hole and the hard material, it is difficult to process, the processing quality and efficiency are low, and the labor intensity is .......

Thread clamping fixture

In the actual production and maintenance process, it is often necessary to machine some parts with external threads. In the production practice, the ordinary method has been used for processing, but there are many problems: 1 directly clamping the external thread, easy to clip Injury the exter.......

Improvement of milling sleeve support sleeve

When using the X62W universal milling machine pylon, the inner hole of the supporting copper sleeve 3 and the shank support part is very worn (Fig. 1), and the support is not reliable, and the new copper sleeve is replaced for a long time. To this end, I designed a milling machine pylon suppor.......
