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. In addition, generally, the thread bears axial tension, but a transverse thrust force, namely a supporting force for transversely supporting the whole piston rod is used, the supporting force can reach dozens of tons, and under the condition that the piston rod is supported to rotate, the thread is easy to loosen, and the piston rod is in danger of falling off after long-term rotation.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: under the condition that one end of the large piston rod is only provided with a short thread, the middle part of the large workpiece cannot be supported and the 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 thread bush locking device, including piston rod, thread bush, cushion and top tight bolt, piston rod one end is provided with the screw thread, the thread bush is established in the cushion, the cushion cover is established in the thread bush, the through-hole has been seted up to thread bush terminal surface symmetry, the top tight bolt passes the through-hole top tight the cushion.
Under the condition that one end of a large piston rod only has a short thread, a cushion block is arranged in the thread sleeve, and the end face of the thread sleeve is tightly propped by a bolt, so that the thread sleeve can be conveniently and reliably locked.
The utility model has the advantages that: the utility model discloses a thread bush locking device 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-cushion block, 2-piston rod, 3-puller bolt and 4-thread sleeve.
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 thread bush locking device, including piston rod 2, thread bush 4, cushion 1 and puller bolt 3, 2 one end of piston rod are provided with the screw thread, the thread bush is established in the cushion 1, 1 cover of cushion is established in the thread bush 4, the through-hole has been seted up to 4 terminal surface symmetries of thread bush, puller bolt 3 passes the through-hole top is tight cushion 1.
Under the condition that one end of a large piston rod 2 only has a short thread, a cushion block 1 is arranged in a thread bush 4, and a bolt is matched and tightly pushed on the end face of the thread bush 4, so that the thread bush 4 can be conveniently and reliably locked.
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.
