Abstract
Description
Technical Field
[0001] The utility model relates to the field of mechanical parts processing, in particular to a special fixture for processing through-holes of a connecting sleeve of an electric furnace pipe network, which is used for processing the split assembly of the connecting sleeve. Background Art
[0002] In the prior art, the electric furnace pipe network connection sleeve is composed of a semicircular tube body, which is a split structure. The semicircular tube has connecting edges at both ends (see Figure 5 、 6 ). To process the split connecting sleeve, an ordinary milling machine, drilling machine or CNC milling machine is generally used to process the plane and screw holes in a single piece. The two halves are then fastened with spacer washers and locking bolts, and the through holes of the connecting sleeve are processed on a conventional lathe or CNC lathe. This is mainly for processing the connecting sleeve on a lathe. In the absence of a suitable fixture, the only way is to use a four-jaw chuck for clamping and alignment, which is extremely inefficient. Since the connecting sleeve is made of copper with a relatively thin wall thickness, it is easy to deform under force, so the clamping force is difficult to control. The parts are not interchangeable after processing. In actual production, the time for clamping and alignment in the processing of a single set of parts greatly exceeds the time for cutting. Utility Model Content
[0003] The utility model aims to solve the above-mentioned deficiencies and provide a special fixture for processing through-holes of electric furnace pipe network connection sleeves, which can self-center, quickly position and clamp, and improve processing efficiency.
[0004] The technical solution of the utility model is: a special fixture for processing through-holes of electric furnace pipe network connecting sleeves, which is characterized by comprising a fixture body, one end of the fixture body is provided with a clamping handle, the other end of the fixture body is an open fork frame structure, and the two inner sides of the open fork frame are provided with hanging surface baffles, each hanging surface baffle is provided with at least one integrated workpiece locating pin and multiple bolt connection holes; the hanging surface baffle and the chuck clamping part are coaxial.
[0005] The above scheme also includes:
[0006] The clamping handle is cylindrical.
[0007] Each overhang plate has an integral workpiece locating pin and two bolt connection holes.
[0008] The advantages of the utility model are: the two halves of the connecting sleeve to be processed are fixed on both sides of the fixture, and the through hole is directly processed at the outer end. The self-centering feature of the fixture is utilized, which saves the time for aligning the workpiece, and can quickly position and clamp. The efficiency can reach about 5 times that of the original processing method. In addition, the clamping force is stable, the parts are not deformed, the processing is stable, the accuracy and interchangeability can be well guaranteed, and the labor intensity of the operator is greatly reduced, thereby improving work efficiency.
[0009] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] See also Figure 1-6 , fixture body 1, clamping handle 2, open fork frame 3, hanging surface baffle 4, integrated workpiece positioning pin 5, bolt connection hole 6, locking bolt 7, through hole 8, workpiece 9.
[0017] See also Figure 1 -6, a fixture specifically designed for machining through-holes in electric furnace pipe network connection sleeves. It comprises a fixture body 1 with a cylindrical gripping handle 2 at one end and an open fork frame 3 at the other end. The open fork frame 3 is flanked by two spaced-apart, support panels 4. Each panel 4 has an integrated workpiece locating pin 5 and two bolt connection holes 6, which are fitted with four sets of locking bolts 7. The panels 4 are coaxial with the chuck mounting area.
[0018] Instructions for Use: First, clamp the cylindrical end of the clamping handle 2 onto the lathe's three-jaw self-centering chuck to enable the fixture's self-centering function. Align the pre-machined locking holes in the two halves of the workpiece 9 with the fixture's integrated workpiece locating pins 5. Place the fixture onto the overhanging baffles 4 on both sides of the fixture body 1. Insert the four locking bolts 7 through the locking holes at the front and rear ends, tighten all of them, and begin machining the through-hole 8 between the two halves of the workpiece 9.
[0019] This device realizes the self-centering function of the workpiece, without the need to align the workpiece, with high positioning accuracy and excellent interchangeability, which can fully meet the technical requirements of the drawings. The clamping force is stable and the workpiece is not deformed. The average working time of a single product is shortened, the labor intensity of the operator is greatly reduced, and labor efficiency is improved.
[0020] It is suitable for use on ordinary lathes and CNC lathes. After actual production testing, it has been found that after being used on ordinary lathes and CNC lathes, the efficiency can reach about 5 times that of the original processing method due to the omission of the alignment time of the original processing method. This fixture uses the self-centering function of the fixture to quickly position and clamp, with stable processing, excellent precision and interchangeability, and can well meet the technical requirements of the workpiece.
[0021] The above description is only a specific implementation of the present invention, and various examples do not limit the essential content of the present invention.
