Description
Technical field
The present invention relates to a kind of two axle screw-rolling machine workpiece pallet systems.
Background technology
A type of the two axle screw-rolling machines as screw-rolling machine, relative to single shaft screw-rolling machine, it does not run into the workpiece dress of complexity
Step is pressed from both sides, processing efficiency greatly improves；Its machine cost is much smaller than three axle screw-rolling machines, and it is applied to out of roundness, concentricity is wanted
Seek the work pieces process of moderate accuracy.As shown in figure 1, two axle screw-rolling machines include quiet rolling wheel 1, dynamic rolling wheel 2 and positioned at both
Between workpiece plate supporting frame 3, in specifically used, find with two axle screw-rolling machines to compared with machining long workpieces end carry out compared with segment spiral shell
When line is processed, with the formation of workpiece end screw thread, the axis of workpiece can slowly raise, and be offset to quiet rolling wheel side,
It offsets and elevated displacement is relevant with the depth of the rolled thread tooth on rolling wheel, typically not over unit millimeter, but should
The amplification of machining long workpieces body is displaced through, the other end of workpiece can be caused to occur significantly to rock, influences the precision of processing, and
And construction worker needs to spend large force to correct this and rock.Simultaneously as in process, two rolling wheels can add all the time
Clamping of workpieces, then want to reduce the large-amplitude sloshing of workpiece the other end, the main rise displacement that must reduce workpiece centre axial direction.
The content of the invention
Goal of the invention：For above-mentioned prior art, a kind of two axle screw-rolling machine workpiece pallet systems are proposed, can be in two axles
When rolled thread machines machining long workpieces, reduce rocking for workpiece end.
Technical scheme：A kind of two axle screw-rolling machine workpiece pallet systems, including pallet body, on the pallet body top
The axially disposed slide rail in portion, the slide rail are provided with the sliding block of threaded groove, and the extreme is provided with positive stop；The band
The sliding block of thread groove is that oblique thread groove is processed in sliding block upper surface, the rolling on the tiltedly rolling wheel of thread groove and screw-rolling machine
Thread tooth is consistent, and the length of the thread groove is more than the length that workpiece need to process thread segment, the hand of spiral of oblique thread groove with
The hand of spiral of shown rolled thread tooth is opposite；The front end of the sliding block of the threaded groove is connected by spring and the positive stop
Connect, the back stretch of the spring range is more than the frictional force between the sliding block and slide rail of threaded groove.
Further, middle position is provided with vertical screw mandrel with locking mechanism, the slide rail and institute in the pallet body
State and connected at the top of vertical screw mandrel, after the slide rail raises, some consistency of thickness of being jumped a queue between the slide rail and pallet body
Cushion block.
Further, the slide rail bottom is provided with the screw mandrel for driving slide rail to be axially moved along the pallet body, the silk
Boom end connects manual turning handle.
Beneficial effect：The axle screw-rolling machine workpiece pallet system of one kind two of the present invention, axially set along pallet body top
Slide rail is put, the sliding block of threaded groove can slide along slide rail, the rolled thread tooth form on the rolling wheel of oblique thread groove and screw-rolling machine
Unanimously, with the progress of processing, the screw thread that machining long workpieces end increasingly generates just can be embedded in oblique thread groove, so allowed for
Longitudinal displacement does not occur substantially for the axis of workpiece, so as to reduce the shaking amplitude of machining long workpieces the other end.
Brief description of the drawings

Specific embodiment
Further explanation is done to the present invention below in conjunction with the accompanying drawings.
As shown in Fig. 2 a kind of two axle screw-rolling machine workpiece pallet systems, including pallet body 31, in pallet body 31
The axially disposed slide rail 32 in top, slide rail 32 are provided with the sliding block 33 of threaded groove, and the end of slide rail 32 is provided with positive stop 34, band
The front end of the sliding block 33 of thread groove is connected by spring 35 with positive stop 34.Middle position is provided with locking in pallet body 31
The vertical screw mandrel 36 of mechanism, slide rail 32 are connected with the vertical top of screw mandrel 36.
The sliding block 33 of threaded groove is that oblique thread groove, the rolling wheel of oblique thread groove and screw-rolling machine are processed in sliding block upper surface
On rolled thread tooth form it is consistent, i.e., the depth of oblique thread groove is consistent with the height of teeth top of rolled thread tooth, between the groove of oblique thread groove
Away from consistent with the pitch of rolled thread tooth, the angle of oblique thread groove and the vertical plane of slide rail 32 is equal to the spiral liter of rolled thread tooth
Angle, the hand of spiral of oblique thread groove are opposite with the hand of spiral of rolled thread tooth.
With the progress that rolled thread is processed, the screw thread that machining long workpieces end increasingly generates just can be embedded in oblique thread groove, by
In the rotation of workpiece, the similar cooperation with bolts and nuts of cooperation of the screw thread that machining long workpieces end increasingly generates and oblique thread groove,
The cooperation can produce axial thrust to the sliding block 33 of threaded groove, realize that workpiece is smooth by the cooperation of sliding block 33 and slide rail 32
Travel forward, therefore, the length of thread groove is more than the length that workpiece need to process thread segment.It is workpiece by the process
Longitudinal displacement does not occur substantially for axis, so as to reduce the shaking amplitude of machining long workpieces the other end.
The front end of the sliding block 33 of threaded groove is connected by spring 35 with positive stop 34, after thread segment machines,
Workpiece is removed, under the action of the spring, sliding block 33 smoothly scope to original position, can be easy to add next workpiece
Work.The back stretch of the range of spring 35 is more than the frictional force between the sliding block 33 and slide rail 32 of threaded groove.
In order to the workpiece suitable for different-diameter screw thread process, it is necessary to adjust the height of the sliding block 33 of threaded groove, this
Realized in embodiment by the vertical screw mandrel 36 with locking mechanism being arranged in pallet body 31, by vertical screw mandrel 36
Driving realize slide rail 32 and threaded groove sliding block 33 rise.After slide rail 32 raises, in order to increase the stability of structure,
Jumped a queue between slide rail 32 and pallet body 31 cushion blocks 37 of some consistency of thickness, as shown in Figure 3.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
