Abstract

The utility model relates to a split type positioning distance sleeve device, which comprises a press roller shaft, a circular pipe, groove-shaped pinch wheels, flat steel, and distance sleeves at the two ends, wherein a plurality of groove-shaped pinch wheels are nested on the press roller shaft, a split type positioning distance sleeve is covered at both sides of the groove-shaped pinch wheel in the middle, the split type distance sleeve at the two ends are covered at the end sides of the front and rear groove-shaped pinch wheels, circular ring shaped distance sleeves are respectively covered at both ends of the press roller shaft, and positioned by being embedded into the key way of the press roller shaft through a long flat key, and both sides of the press roller shaft are firmly fastened through circular nuts. The utility model has the advantages that the disassemble and the assemble are convenient; because the distance between the two split type positioning distance sleeves is 0.2 to 0.3 mm larger than the thickness of the flat steel in the tight pressing state, the flat steel is guaranteed to be at the center of the circular pipe to enable the normal performance of welding, therefore, the utility model has the functions of a flat steel positioning pinch wheel device and a positioning pressed block device in the original device, and simultaneously, the function of circular pipe pitch positioning.

Description

Dissection type positioning spacer device

Technical field

The utility model relates to a kind of positioning spacer device of tube panel welding machine, particularly a kind of dissection type positioning spacer device.

Background technology

Pitch between the two tubes of the multielectrode gas-shielded welded tube screen of boiler fin panel casing welding machine is to rely on the positioning spacer at flute profile pressure roller and middle and two ends to guarantee; Band steel then is to be guaranteed by band steel location pinch roller and band steel location briquetting in the center of pipe.When the pitch of tube panel and specification change, must be with all sheaves and positioning spacer complete removal, and then the sheave and the positioning spacer of new spec installed on each pressure roller shaft.Have 77 flute profile running rollers of 11 axles and 88 positioning spacers will be changed for the welding machine of 12 electrodes and 20 electrodes, then the height of linearity, band steel pinch roller and the band steel briquetting of flute profile pinch roller is adjusted, to expend the more time like this, when welding for wide band steel, rely on band steel location pinch roller and briquetting, distortion when often being difficult to the control welding, and defective such as postwelding band steel position inclination appears.

Summary of the invention

Technical problem of the present utility model is the dissection type positioning spacer device that will provide a kind of and change conveniently, can the pipe location can compress again band steel.

In order to solve above technical problem, the utility model provides a kind of dissection type positioning spacer device, comprise pressure roller shaft, pipe, the flute profile pinch roller, band steel, the two ends spacer, be set with several flute profile pinch rollers on the pressure roller shaft, be set with the dissection type positioning spacer in middle flute profile pinch roller both sides, the distolateral dissection type two ends spacer that is set with of former and later two flute profile pinch rollers, each suit one circular spacer at the pressure roller shaft two ends, be inlaid in by long flat key in the keyway of pressure roller shaft and locate, the pressure roller shaft two ends tighten up with round nut, rely on the round nut at two ends just flute profile pinch roller on the pressure roller shaft and dissection type positioning spacer can be fixed into a complete pressure roller assembly tightly.

Described dissection type positioning spacer is two semi-annular shapes, and boss is made in its both sides.

Described dissection type two ends spacer is two semi-annular shapes, and boss is made in its both sides.

Described flute profile pinch roller, its both sides are made the shoulder that is complementary with dissection type positioning spacer both sides boss.

The distolateral shoulder that is complementary with spacer both sides, dissection type two ends boss of making of described circular spacer.

When pressure roller shaft compresses pipe up and down, being positioned at up and down, pressure roller shaft both sides dissection type positioning spacer compresses band steel, big 0.2mm～the 0.3mm of thickness of the gap ratio band steel between two semicircles of dissection type positioning spacer, thus guarantee that band steel is in the center of pipe, welding can normally be carried out.

The width of dissection type positioning spacer is by the decision of pipe pitch, and the dissection type positioning spacer positions pipe, the width W=P-Q of dissection type positioning spacer,

Wherein: P-pipe pitch;

The width of Q-flute profile pressure roller.

Superior effect of the present utility model is:

1) is convenient to dismounting: when the pipe external diameter is constant, when only the pipe pitch changes, the round nut at pressure roller shaft two ends is unclamped, the flute profile pressure roller is drawn back a segment distance, just can position the replacing of spacer like a cork, save the time of changing frock;

2) the dissection type positioning spacer is sleeved on the pressure roller shaft and rotates with the flute profile running roller, because the distance between the two dissection type positioning spacers is than the big 0.2mm～0.3mm of thickness of band steel under impaction state, therefore band steel can be limited to the pipe center line up and down between 0.1mm～0.15mm, both play band steel location pressing wheel device and the effect of locating briquetting device in the original equipment this moment, played the effect of pipe pitch location simultaneously again.

The specific embodiment

See also shown in the accompanying drawing, the utility model will be further described.

As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, the utility model provides a kind of dissection type positioning spacer device, comprise pressure roller shaft, pipe 5, flute profile pinch roller 4, band steel 6, the two ends spacer, be set with several flute profile pinch rollers 4 on the pressure roller shaft, be set with dissection type positioning spacer 3 in middle flute profile pinch roller 4 both sides, the distolateral dissection type two ends spacer 9 that is set with of former and later two flute profile pinch rollers 4, each suit one circular spacer 10 at the pressure roller shaft two ends, be inlaid in by long flat key 8 in the keyway of pressure roller shaft and locate, the pressure roller shaft two ends tighten up with round nut 1, rely on the round nut 1 at two ends just flute profile pinch roller 4 on the pressure roller shaft and dissection type positioning spacer 3 can be fixed into a complete pressure roller assembly tightly.
