Problems solved by technology

[0002] During the processing of pipe parts, it is necessary to carry out radial drilling on its outer circle in equal divisions. At present, the commonly used drilling process is to first clamp the workpiece, and then according to the first drilling Drilling operation at the same position, when it is necessary to drill another hole after rotating the equal division, the workpiece needs to be unloaded, and then rotated to the angle that needs to be drilled, and then drilled after secondary clamping and alignment, the above In the process of the process, it is necessary to perform secondary clamping and alignment on the parts, which will bring certain errors and affect the processing quality of the workpiece.

Embodiment 1

[0029] Such as Figure 1-2 As shown in the figure, the high-precision indexing turntable is used for the equi-indexed drilling of the outer circle of pipe parts. The top of the base 1 is fixedly installed with the first support plate 2 and the second support plate 15. The first support plate 2 and the second support plate A main shaft 4 is supported between the two support plates 15, and a first threaded section 6 and a second threaded section 13 are processed on the main shaft 4, and a first threaded sleeve 7 is mounted on the first threaded section 6 through thread transmission. , the second threaded segment 13 is fitted with a second threaded sleeve 12 through screw transmission, the side wall of the first threaded sleeve 7 is hinged with a first connecting rod 19, and the other end of the first connecting rod 19 Hinged on the side wall of the indexing turntable 18 by the first pin shaft 17, the second connecting rod 11 is hinged on the side wall of the second threaded slee...

Embodiment 2

[0037] The method for operating a high-precision indexing turntable used for the equal indexing drilling of outer circles of pipe parts is characterized in that it includes the following steps:

[0038] Step 1, clamping the pipe parts to be drilled to the three-jaw chuck fixture on the side wall of the indexing turntable 18;

[0039] Step 2, start the drilling equipment to drill the first hole on the outer wall of the pipe;

[0040] Step 3: After the drilling of the first hole is completed, drive the sprocket disc 3 to rotate through the chain transmission mechanism, and then the sprocket disc 3 drives the main shaft 4 to rotate, and the main shaft 4 synchronously drives the first thread segment 6 and the second The two threaded sections 13 rotate, and then the first threaded sleeve 7 and the second threaded sleeve 12 are synchronously driven by the first threaded section 6 and the second threaded section 13, and then the first threaded sleeve 7 and the second threaded sleeve ...

Abstract

The invention discloses a high-precision indexing turntable and an operation method for equal indexing drilling of outer circles of pipe parts. It includes a first support plate and a second support plate fixedly installed on the top of the base, and the first support plate A main shaft is supported between the second support plate and a first threaded section and a second threaded section are processed on the main shaft, a first threaded sleeve is installed on the first threaded section through thread transmission, and the second threaded section is mounted on the first threaded section. A second threaded sleeve is installed on the threaded section through thread transmission, and a first connecting rod is hinged on the side wall of the first threaded sleeve, and the other end of the first connecting rod is hinged on the indexing turntable through the first pin shaft. On the side wall of the second threaded sleeve, a second connecting rod is hinged on the side wall, and the other end of the second connecting rod is hinged on the side wall of the indexing turntable through a second pin shaft.

Description

technical field [0001] The invention relates to the technical field of pipe parts processing, in particular to a high-precision indexing turntable and an operation method for equally indexed drilling of outer circles of pipe parts. Background technique [0002] During the processing of pipe parts, it is necessary to carry out radial drilling on its outer circle in equal divisions. At present, the commonly used drilling process is to first clamp the workpiece, and then according to the first drilling When it is necessary to drill another hole position after rotating the same division, the workpiece needs to be unloaded, then rotated to the angle that needs to be drilled, and then drilled after secondary clamping and alignment. In the process of the process, it is necessary to perform secondary clamping and alignment of the parts, which will bring certain errors and affect the processing quality of the workpiece. Contents of the invention [0003] The new model provides a h...
