Abstract

The utility model relates to a pipe fitting clamping mechanism. A first pipe clamping block and a first hinge pin are mounted at two ends of a first finger arm, a second pipe clamping block and a second hinge pin are mounted at two ends of a second finger arm, the tip of the first hinge pin and the tip of the second hinge pin respectively extend out of slide grooves and are connected to corresponding ends by return springs, the first hinge pin and the second hinge pin slide on the slide grooves, the first finger arm and the second finger arm are respectively hinged on a bed plate by a first fixing hinge pin and a second fixing hinge pin, the first fixing hinge pin is arranged between the first pipe clamping block and the first hinge pin, the second fixing hinge pin is disposed between the second pipe clamping block and the second hinge pin, corresponding rollers are arranged on the first hinge pin and the second hinge pin, a push block with two guiding surfaces is mounted at the front end of a pushing shaft of a pushing cylinder, and a wide-pitch position and a narrow-pitch position are formed by the two guiding surfaces. The pipe fitting clamping mechanism has the advantages that a copper pipe bent by a numerical-control pipe bending machine is automatically taken out, the pipe fitting clamping mechanism is large in the opening and applicable to clamping copper pipes with different diameters, and automatic production of the numerical-control pipe bending machine is realized.

Description

A kind of pipe fitting clamping device

(1) technical field

The utility model relates to a kind of pipe fitting clamping device.

(2) background technology

Produce heat exchanger and need a large amount of U type pipes; In the process of producing, need and will take out through the U type pipe of the bend pipe of CNC tube bending machine, way in the past is that the workman takes out the U type pipe in the CNC tube bending machine; Inefficiency, dangerous so not only, and labour intensity is big.

(3) summary of the invention

For addressing the above problem, the utility model provides a kind of pipe fitting clamping device, will take out automatically at the curved good copper pipe of CNC tube bending machine, realizes the automated production of CNC tube bending machine, operates steadily, and production efficiency is high.

For this reason, the utility model adopts following scheme to achieve the above object:

A kind of pipe fitting clamping device; Comprise support, it is characterized in that: also comprise promoting cylinder, back-moving spring, first-hand index arm, second-hand's index arm, the first clamp piece, the second clamp piece, first bearing pin, second bearing pin, first fixed pin shaft and second fixed pin shaft;

The two ends of first-hand index arm are installed the first clamp piece and first bearing pin respectively; The two ends of second-hand's index arm are installed the second clamp piece and second bearing pin respectively; Support is provided with chute; First bearing pin and second bearing pin two ends separately stretch out and are connected corresponding end by back-moving spring from chute, first bearing pin and the slippage on chute of second bearing pin, and first-hand index arm and second-hand's index arm are hinged on the support through first fixed pin shaft and second fixed pin shaft respectively; Said first fixed pin shaft is between the said first clamp piece and first bearing pin, and said second fixed pin shaft is between the said second clamp piece and second bearing pin;

The said first clamp piece is provided with first cavity, and the second clamp piece is provided with second cavity, and the first clamp piece and the second clamp piece are close together and make first cavity and second cavity merge formation copper pipe dop;

Corresponding first roller and second roller are housed respectively on said first bearing pin and second bearing pin; The impeller-hub front end that promotes cylinder is equipped with pushing block; Pushing block is provided with two guiding faces, and two guiding faces form spacing broad place and the narrower place of spacing, when first roller and second roller are positioned at spacing broad place; The pulling force that two guiding face distending first rollers and second roller overcome back-moving spring makes first bearing pin and the second bearing pin spacing become big; Make the first clamp piece and the second clamp piece near, when first roller and second roller were positioned at the narrower place of spacing, first roller and second roller pushed two guiding faces respectively; Under the tension of back-moving spring, make first bearing pin and the second bearing pin pitch smaller, make the first clamp piece and the second clamp piece separately.

Above-mentioned a kind of pipe fitting clamping device is characterized in that: said first roller and second roller are bearing.

The advantage of the utility model is: the pipe fitting clamping device will take out at the curved good copper pipe of CNC tube bending machine automatically, and the folding degree of clamp piece is bigger, is fit to the clamping of different tube diameters copper pipe, realizes the automated production of CNC tube bending machine, operates steadily, and production efficiency is high.

Fig. 2 is the utility model first clamp piece and the second clamp piece generalized section when separating;

Generalized section when Fig. 3 is the utility model first clamp piece and second clamp piece closure.

(5) specific embodiment

Below in conjunction with accompanying drawing the utility model is done further detailed explanation.

Embodiment: a kind of pipe fitting clamping device comprises support 1, promotes cylinder 2, back-moving spring 3, first-hand index arm 41, second-hand's index arm 42, the first clamp piece 51, the second clamp piece 52, first bearing pin 61, second bearing pin 62, first fixed pin shaft 71 and second fixed pin shaft 72.

The two ends of first-hand index arm 41 are installed the first clamp piece 51 and first bearing pin 61 respectively; The two ends of second-hand's index arm 42 are installed the second clamp piece 52 and second bearing pin 62 respectively; Support 1 is provided with chute 8; First bearing pin 61 and second bearing pin 62 two ends separately stretch out and are connected corresponding end by back-moving spring 3 from chute 8; First bearing pin 61 and second bearing pin 62 slippage on chute 8; First-hand index arm 41 is hinged on the support 1 through first fixed pin shaft 71 and second fixed pin shaft 72 respectively with second-hand's index arm 42, and said first fixed pin shaft 71 is between the said first clamp piece 51 and first bearing pin 61, and said second fixed pin shaft 72 is between the said second clamp piece 52 and second bearing pin 62.

The said first clamp piece 51 is provided with first cavity, 91, the second clamp pieces 52 and is provided with second cavity, 92, the first clamp pieces 51 and the second clamp piece 52 and is close together and first cavity 91 and second cavity 92 is merged form copper pipe dops 93.

Corresponding first roller 101 and second roller 102 are housed respectively on said first bearing pin 61 and second bearing pin 62; The impeller-hub front end that promotes cylinder 2 is equipped with pushing block 11; Pushing block 11 is provided with two guiding face 11-1; Two guiding face 11-1 form spacing broad 11-11 of place and the narrower 11-12 of place of spacing; When first roller 101 and second roller 102 were positioned at the spacing broad 11-11 of place, the pulling force that two guiding face 11-1 distending first rollers 101 and second roller 102 overcome back-moving spring 3 made first bearing pin 61 and second bearing pin, 62 spacings become big, make the first clamp piece 51 and the second clamp piece 52 near; When first roller 101 and second roller 102 are positioned at the narrower 11-12 of place of spacing; First roller 101 and second roller 102 push two guiding face 11-1 respectively; Under the tension of back-moving spring 3, make first bearing pin 61 and second bearing pin, 62 pitch smaller, the first clamp piece 51 and the second clamp piece were opened in 52 minutes.
