Specific embodiment
Embodiment shown in reference to the accompanying drawing is further described the utility model.
As shown in Figure 1, single-cylinder diesel engine crankshaft rolled thread tooling includes be clamped in 9 both ends of single-cylinder diesel engine crankshaft first
Top 11 and second top 21, the first dead head 12, the second dead head 22 and supporting mechanism 3.
First top 11 is arranged in the first dead head 12, and second top 21 is arranged in the second dead head 22.With first
Dead head 12, which is connected, is connected to a cylinder 19, and cylinder 19 can push against mobile first top 11, and first top 11 is top first
Axial position in seat 12 is adjustable setting, and such cylinder 19 can work first top 11 against extension or retraction, with
Conducive to assembly single-cylinder diesel engine crankshaft 9.
First dead head 12 and the second dead head 22 are rotatable setting, and the first dead head 12 and the first pedestal 14 are cut with scissors
It connects, the second dead head 22 and the second pedestal 24 hinged (reference can be made to Fig. 6).First pedestal 14 and the second pedestal 24 are arranged at bottom plate
On 7, the lower section of the first pedestal 14 and the second pedestal 24 is provided with raised line, and fluted, raised line and groove cooperation are arranged on bottom plate 7
So that the distance between the first pedestal 14 and the second pedestal 24 are adjustable.
If Fig. 7, first top 11 is arranged in first sleeve 13, bearing 18 is provided in first sleeve 13, first is top
11 are set in bearing 18, therefore first top 11 can drive rotation by single-cylinder diesel engine crankshaft 9, before first sleeve 13
Dustproof cover 16 is additionally provided at end opening to prevent dust from entering in first sleeve 13.Such as Fig. 6,13 sets of first sleeve on the first top
In sharp seat 12.And the lower section of first sleeve 13 is provided with feather key 131, is provided in the first dead head 12 and feather key 131
The guide groove 121 of cooperation, cylinder 19 can drive first sleeve 13 move forward or back, and then drive first it is top 11 advance or after
It moves back namely first top 11 axial position is adjustable.Second top 21 is similar to first top 11 set-up mode, only
It is not provided with feather key.(reference can be made to Fig. 2) second top 21 is arranged in second sleeve 23, is provided with bearing in second sleeve 23
18, second top 21 is set in bearing 18, therefore second top 21 can drive rotation by single-cylinder diesel engine crankshaft 9.Second
23 sets of sleeve are mutually fixed in the second pedestal 24 and between the second pedestal 24, but second sleeve 23 is in the second pedestal 24
Axial position can finely tune.Circular hole is provided on the wall of second pedestal 24 to be screwed into fastening bolt and push against the second pedestal
24.When finely tuning 23 axial position of second sleeve, loosers a bolt, second sleeve 23 is moved axially, then tighten bolt, therefore can fit
The single-cylinder diesel engine crankshaft 9 different for length.Above assembly method is convenient, and is conducive to the first top 11 or second top of replacement
Point 21.
As shown in figure 5, being additionally provided with elastic parts 17, elastic parts 17 towards the first dead head 12 in the first pedestal 14
Including the spring 171 being arranged in the first pedestal 14 and the steel ball 172 on 171 top of spring is set, steel ball 172 is against first
12 lower surface of dead head.Since the first dead head 12 and the first pedestal 14 are hinged, the first dead head 12 can surround the first pedestal
14 have the rotation of certain allowed band, and elastic parts 17 can jack up the rotation of the first dead head 12.Elastic parts 17 is also set simultaneously
It sets in the second pedestal 24.In other technical solutions, elastic parts 17 can be positioned only at the first pedestal 14 and the second pedestal 24
One of, Fig. 2 is seen far from dead axle cylindrical die roll 82(as long as rotation single-cylinder diesel engine crankshaft 9 can be jacked up).In conjunction with Fig. 2,
When carrying out thread rolling operation to single-cylinder diesel engine crankshaft 9, namely in its surface rolling screw thread, by moving axis cylindrical die roll 81 and dead axle
Cylindrical die roll 82 is clamped single-cylinder diesel engine crankshaft 9, and specifically moving axis cylindrical die roll 81, which advances, clamps, moving axis cylindrical die roll 81 and fixed
The rotation of 82 same direction of axis cylindrical die roll carries out rolled thread.After the completion of rolled thread, moving axis cylindrical die roll 81 retreats (withdrawing).At this moment elastic parts
17 active force accounts for leading role, the first dead head 12 and the rotation of the second dead head 22 is jacked up, thus by single-cylinder diesel engine crankshaft 9
Rotation is separated with dead axle cylindrical die roll 82.
Such as Fig. 1, for supporting mechanism 3 for supporting single-cylinder diesel engine crankshaft 9 in advance, pre- supporting mechanism 3 includes the first support plate 31
With the second support plate 32.V-arrangement is presented in the top of first support plate 31, as shown in Figure 3；The top of second support plate 32 is horizontal flat
Face, as shown in Figure 4.When top is that the first support plate 31 of V-arrangement can be such that single-cylinder diesel engine crankshaft 9 is placed on supporting mechanism 3
It does not tumble.When single-cylinder diesel engine crankshaft 9 is placed on supporting mechanism 3, height when relative to thread rolling operation is slightly lower, that is,
Height power when being clamped between first top 11 and second top 21 compared to single-cylinder diesel engine crankshaft 9 is slightly lower.Supporting mechanism 3
Only temporarily place single-cylinder diesel engine crankshaft 9, when single-cylinder diesel engine crankshaft 9 is placed on supporting mechanism 3, single-cylinder diesel engine crankshaft
9 both ends center is slightly below respectively at first top 11 and second top 21 tip, and then cylinder 19 works, and pushes the first top
Point 11 moves ahead, and single-cylinder diesel engine crankshaft 9 is gradually lifted and clamped by first top 11 and second top 21.At this moment single cylinder diesel
9 lower surface of crankshaft is about 0.1mm-0.2mm, single-cylinder diesel engine crankshaft 9 at a distance from the first support plate 31 and the second support plate 32
Rolled thread will not be damaged when rotating by the first support plate 31 and the second support plate 32.In the present embodiment, the first support plate 31 and second
The height of support plate 32 can also be adjusted, and to adapt to different single-cylinder diesel engine crankshafts 9, concrete mode is the first support plate
31 and second are respectively provided with two vertical waist round hole in support plate 32, and by waist round hole and bolt by the first support plate 31 and the
Two support plates 32 are separately fixed on a mounting plate, and waist round hole allows the height of the first support plate 31 and the second support plate 32 can
It adjusts.In addition, being additionally provided with raised line below the mounting plate, raised line imbeds in the groove of bottom plate 7, such mounting plate such as Fig. 1
Position is adjustable.In other technical solutions, the top that the first support plate 31 and the second support plate 32 can also be arranged is V
Shape.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
