Problems solved by technology

The end face processing fixture of the steel pipe blank currently used is the upper and lower seat type, and the clamping surface is the same size as the outer diameter of the tube blank to be processed. When clamping, the upper seat is removed, the tube blank is hoisted, and the upper seat is installed again for clamping. The processing efficiency is extremely low. ;In addition, each specification of tube blanks corresponds to one size of fixture. When changing tube blanks of different specifications, the previous processing fixture must be removed and another fixture must be installed, which is time-consuming and laborious; due to the manufacture of multiple specifications of fixtures, it also greatly increases production. cost

Embodiment 1

[0025] Such as figure 1 The shown multi-standard steel pipe end face processing quick-change tooling 2 is installed on a workbench 1 with a T-shaped groove, and the quick-change tooling 2 is welded by Q345 steel plates. The quick-change tooling 2 includes a V-shaped supporting base 201 installed on the T-shaped groove, and a pressing plate column 202 and a pressing rod 203 installed on the left and right ends of the V-shaped supporting base 201 . Wherein, the pressing plate column 202 is fixed on the V-shaped supporting base 201, and the pressing rod 203 is connected with the V-shaped supporting base 201 through the pin shaft 206, so the pressing rod 203 can freely rotate and open with the pin shaft 206 as the base point. The outer circle of the lower part of the V-shaped support base 201, the upper pressing plate 205 is arranged transversely on the upper part of the pressing plate column 202 and the pressing rod 203, and the V-shaped pressing block 204 is arranged under the u...

Embodiment 2

[0030] When processing steel pipes with different pipe diameters, in addition to using the method of adding pads in the first embodiment, an adjustment mechanism can be added on the basis of the quick-change tooling 2 provided in the first embodiment. The specific structure is as follows: Figure 3 ~ Figure 5 As shown, the top of the pressure plate column 202 of the quick-change tool is provided with an upper pressure plate chute 211. According to the steel pipe size of various specifications to be processed, a plurality of card slots 2111 are arranged in the upper pressure plate chute 211, and each side of the card slot 2111 is preferably The engraved line 2112 of the steel pipe size of each specification is set, so that the operator can quickly adjust the quick-change tooling according to the steel pipe size to be processed. When the upper pressing plate 205 is opened, the pin shaft 206 can slide in the upper pressing plate chute 211 of the pressing plate column 202; further...

Abstract

The invention discloses a multi-standard steel pipe end face machining fast-changing tooling which can be opened flexibly to assemble and disassemble a steel pipe fast and capable of being applied to steel pipes of different sizes. The multi-standard steel pipe end face machining fast-changing tooling achieves the purpose of machining multi-standard steel pipe end faces on one working bench. The multi-standard steel pipe face machining fast-changing tooling comprises a V-shaped bearing base seat arranged on the working bench, a pressing board stand column and a pressing rod respectively arranged on the left end and the right end of the V-shaped bearing base seat, the pressing board stand column is fixed on the V-shaped bearing seat, and the pressing rod is connected with the V-shaped bearing seat through a pin shaft. pressing boards are arranged on the upper portions of the pressing board stand column and the pressing rod horizontally, V-shaped pressing blocks are arranged on the lower portions of the pressing boards, the left ends of the pressing boards are connected with the pressing board stand column through a pin shaft, a bar-shaped groove is arranged in the upper end of the pressing rod, and a pressing nut is arranged on the top portion of the pressing rod.

Description

technical field [0001] The invention relates to machining tools, in particular to a clamping device suitable for steel pipes of various specifications. Background technique [0002] When processing products with steel pipe blanks, it is necessary to process the end face of the steel pipe after clamping the steel pipe with a clamp. The end face processing fixture of the steel pipe blank currently used is the upper and lower seat type, and the clamping surface is the same size as the outer diameter of the tube blank to be processed. When clamping, the upper seat is removed, the tube blank is hoisted, and the upper seat is installed again for clamping. The processing efficiency is extremely low. ;In addition, each specification of tube blanks corresponds to one size of fixture. When changing tube blanks of different specifications, the previous processing fixture must be removed and another fixture must be installed, which is time-consuming and laborious; due to the manufacture...
