The utility model provides a pair of thread bush locking device simple to operate, locking is reliable, can protect the screw thread at piston rod both ends effectively, has solved the difficulty that big work piece middle part can not hold in the palm, both ends can not push up.
Description
Technical Field
The utility model relates to a locking device specifically is a thread bush locking device.
Background
In the processes of spraying and grinding of the piston rod, a large overweight workpiece always appears, two ends cannot be clamped by a tip and can only be supported by two ends which are generally in large-size threaded connection, and a rolling sleeve is connected by threads and used for supporting the workpiece.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: under the condition that two ends of a large piston rod are provided with longer threads, the middle part of a large workpiece cannot be supported and two ends cannot be jacked in the processes of spraying and grinding of the piston rod.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a pair of thread bush locking device, including thread bush, thread locking circle, tie bolt and piston rod, the piston rod both ends all are provided with thread locking circle and screw thread, the screw thread is located the outside of thread locking circle, the screw thread cover is established in the thread bush, tie bolt passes the thread locking circle with the thread bush is connected.
The thread sleeve comprises a rolling sleeve and a supporting sleeve, the rolling sleeve is fixedly connected with the supporting sleeve, the rolling sleeve is used for helping the large overweight workpiece to enter the thread sleeve, and the supporting sleeve is used for supporting the large overweight workpiece and protecting threads at two ends of the large overweight workpiece; the end face of the rolling sleeve is symmetrically provided with first through holes, the end face of the locking ring is symmetrically provided with second through holes, and the first through holes and the second through holes are connected through tensioning bolts; a thread locking ring is added, the sleeve and the ring are tightened by using a tightening bolt, when the tightening bolt is not used for tightening originally, the tightening is impossible, and if the tightening is not adopted, the danger of falling off during processing can be generated, and the thread can be damaged.
The utility model has the advantages that: the utility model relates to a thread bush locking device through increasing a thread lock ring, has solved the difficulty that big work piece middle part can not hold in the palm, both ends can not push up, simultaneously, the utility model discloses simple to operate, locking are reliable, can protect the screw thread at piston rod both ends effectively.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
in the figure: 1-thread, 2-tension bolt, 3-piston rod, 4-thread sleeve, 5-thread locking ring.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, the utility model provides a pair of thread bush locking device, including thread bush 4, thread locking circle 5, tie bolt 2 and piston rod 3, 3 both ends of piston rod all are provided with thread locking circle 5 and screw thread 1, screw thread 1 is located the outside of thread locking circle 5, 1 cover of screw thread is established in the thread bush 4, tie bolt 2 passes thread locking circle 5 with thread bush 4 is connected.
The thread bushing 4 comprises a rolling bushing and a supporting bushing, the rolling bushing is fixedly connected with the supporting bushing, the rolling bushing is used for helping the large overweight workpiece to enter the thread bushing 4, and the supporting bushing is used for supporting the large overweight workpiece and protecting threads 1 at two ends of the large overweight workpiece; the end surface of the rolling sleeve is symmetrically provided with first through holes, the end surface of the thread locking ring 5 is symmetrically provided with second through holes, and the first through holes and the second through holes are connected through the tensioning bolts 2; now increase a screw thread locking circle 5, with tie bolt 2 will overlap with the circle taut can, originally when not adopting tie bolt 2 taut, need screw up like this when tight, if do not screw up, will have the danger that drops during processing, still can destroy spiral shell 1.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
