When electric tube expander carries out non-contraction tube expanding, the U-shaped end of two-port and bottom of long U-tube heat exchanger workpiece is not respectively by
Same clamping device is clamped fixation, now with more universal clamping device.But in actual production, heat exchanger workpiece
Composition it is endless be all long U-tube, be mixed into straight tube on demand sometimes, or workpiece is all straight tube, the folder of straight tube upper end completely
Compact form is constant, but without completely applicable straight tube lower end clamping device, is particularly capable of the clamping device of Automated condtrol,
Therefore need to develop the clamping device of straight tube lower end, to adapt to the demand of actual production.
Utility model content
Technical problem to be solved in the utility model is to overcome the drawbacks described above of prior art and provide a kind of electric tube expander
Workpiece clamping device, for clamping the lower end of straight tube, the need for meeting actual production.
The utility model solve the technical scheme that is used of above-mentioned technical problem for：
The Workpiece clamping device of electric tube expander, including stationary jaw, push rod, spring, moving sleeve, shifting axle；The fixation
Clamping jaw head sets diameter more than the expansion arc of bottom linkage section, and expansion arc vertically cracks provided with several, the stationary jaw
Centre sets through hole, and through hole can accommodate the top bar for being also set up in the push rod, through hole and limiting the spring movement, described
Vertical long gain through hole is set on the periphery between stationary jaw linkage section and expansion arc；The push rod head sets lateral shaft
Hole, bottom sets spring lower limit step, and push rod lower end can be connected with impeller；The moving sleeve is enclosed on stationary jaw head
Linkage section and expansion arc between, moving sleeve head is provided with through hole, and the shifting axle is passed through push rod and movement after long gain
Both sleeves are fixed together；The spring housing is on push rod, and lower spring end getting out of a predicament or an embarrassing situation on push rod is spacing, spring upper end by
Top bar in stationary jaw through hole is spacing；When clamping pipe, push rod moves up that drive moving sleeve is moved up and to compress several vertical
Crack, several vertical interior pipe fittings that crack are pinned, while spring-compressed；When unclamping pipe, spring reset drives push rod and movement
Sleeve resets, and reinstatement of vertically cracking, pipe fitting can free in and out the head of stationary jaw.
Preferably, above-mentioned moving sleeve, push rod set mobile axis hole, and shifting axle is fixed on moving sleeve by axis hole, pushed away
On bar.
The utility model is due to the lower end for coordinating movable sleeving to pin and unlock straight tube using push rod and back-moving spring, therefore
The Automated condtrol of pipe clamping device can conveniently be realized.

Embodiment
The utility model is further described below in conjunction with accompanying drawing embodiment.
As shown in figure 1, the Workpiece clamping device of electric tube expander, including stationary jaw 1, push rod 2, spring 3, moving sleeve 4, shifting
Moving axis 5.
As shown in Fig. 2 the head of stationary jaw 1 sets diameter to be more than the expansion arc 105 of bottom linkage section 104, expand
Section 104 vertical cracks 102 provided with several.When normal, pipe fitting 6 can free in and out the head of stationary jaw 1；Several vertically crack
During 102 compression, pipe fitting 6 therein can be pinned, Fig. 5 is seen.
Through hole 103 is set in the middle of the stationary jaw 1, through hole 103 can accommodate push rod 2, and push rod 2 can be in through hole 106
Middle movement.The step 103 of the movement of limited spring 3 is also set up in through hole 106.
Vertical long gain through hole 101 is set on periphery between the linkage section 104 of stationary jaw 1 and expansion arc 105,
Vertical long gain through hole 101 is corresponding with the horizontal axis hole 201 at the top of push rod 2.
The head of push rod 2 sets horizontal axis hole 201, and bottom sets spring retainer step 202, and spring 3 is enclosed on push rod 2
And it is spacing by limited step 202, the lower end of push rod 2 can be with impeller（It is not drawn into figure）Connection.
As shown in figure 4, the moving sleeve 4 is enclosed between the linkage section 104 on the head of stationary jaw 1 and expansion arc 105, move
The head of moving sleeve 4 is provided with through hole 401, and the shifting axle 5 is passed through push rod 2 and shifting after through hole 401, long gain 101, through hole 201
Both moving sleeves 4 are fixed together.
As shown in figure 3, the spring 3 is enclosed on push rod 2, step 202 of the lower end of spring 3 on push rod 2 is spacing, spring 3
Step 103 of the upper end in stationary jaw 1 is spacing.
When pipe fitting 6 needs expanded joint, pipe fitting 6 inserts the head of the stationary jaw 1 of clamping device, and then impeller is pushed up
Dynamic push rod 2, is connected to the shifting axle 5 on the head of push rod 2 upward sliding in long gain 101, drives moving sleeve 4 to move up and sets
Set a distance, so that cracking for the head of stationary jaw 1 102 is closed up, so as to pipe fitting 6 be clamped, as shown in Figure 5.
After the completion of the expanded joint of pipe fitting 6, push rod 2 lays down the external force of impeller, under the spring-force driven dual of spring 3, and push rod 2 is past
Under move back, make the shifting axle 5 on the head of push rod 2 slide downward in long gain 101, so as to drive moving sleeve 4 to move down setting
Distance, opens the head of stationary jaw 1 and unclamps pipe fitting 6, see Fig. 1, so as to remove pipe fitting 6.
