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 for outer circle equal-indexing drilling of tubular parts and an operation method. According to the high-precision indexing turntable, the top of a base is fixedly provided with a first supporting plate and a second supporting plate, and a main shaft is installed between the first supporting plate and the second supporting plate in a supported manner; a first threaded section and a second threaded section are machined on the main shaft, the first threaded section is provided with a first threaded sleeve in a threaded transmission fitmanner, and the second threaded section is provided with a second threaded sleeve in a threaded transmission fit manner; a first connecting rod is hinged to the side wall of the first threaded sleeve,and the other end of the first connecting rod is hinged to the side wall of the indexing turntable through a first pin shaft; and a second connecting rod is hinged to the side wall of the second threaded sleeve, and the other end of the second connecting rod is hinged to 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...
