Detailed description of the preferred embodiments
The present invention will be further described with reference to the following examples, which are not intended to limit the scope of the present invention, but are intended to be covered by the appended claims in any way.
The specific embodiment of the present invention is such: referring to fig. 1-5, a quick dismounting tool for a rotary joint comprises a pull rod 1, wherein a drawing hammer 2 is arranged on the pull rod 1, a connector 3 is arranged at the front end of the pull rod 1, a connecting disc 4 matched with the end face of the rotary joint is arranged at the front end of the connector 3, and a connecting hole 5 matched with a rotary joint end cover mounting hole 13 on the end face of a rotary joint 12 is arranged on the connecting disc 4.
Among this rotary joint quick assembly disassembly tool, connection pad 4 is connected through bolted construction and rotary joint end cover mounting hole 13 on the 12 terminal surfaces of rotary joint, with connection pad 4 and rotary joint 12 locking, then can extract rotary joint 12 in constrictive space through use tool or the hammer 2 of drawing on the pull rod 1 of manual pulling, alright realize carrying out the dismouting to rotary joint 12 fast under the condition of not dismantling spindle motor in narrow and small space, the application of force when being convenient for pull by hand is convenient, or use tool presss from both sides tightly to draw hammer 2 and takes out rotary joint 12 through the instrument application of force.
This assembly and disassembly tools realizes through pull rod 1, connection pad 4 with by being connected of dismantlement part, plays the effect of connecting the bridge, has changed application of force effect point, has made things convenient for staff's operation greatly.
In this embodiment, the rear end of connector 3 is equipped with the screw 6 of being connected with pull rod 1, and the both ends of connector 3 are equipped with screw rod portion 7, through threaded connection, connect fast, are convenient for change the pull rod 1 of different length.
In this embodiment, draw and to be equipped with the trepanning 8 with the outer wall looks adaptation of pull rod 1 in the hammer 2, the pore wall both sides of trepanning 8 are equipped with two axial spouts 9, and the both ends that lie in axial spout 9 on the trepanning 8 pore wall are equipped with the spacing groove 10 of circumference extension, and the outer wall both sides of pull rod 1 are equipped with the fixture block 11 with axial spout 9 and spacing groove 10 looks adaptation. During pull rod 1 inserts the trepanning 8 of drawing hammer 2, under the guide effect of fixture block 11 and axial spout 9, pull rod 1 steadily slides, then, makes fixture block 11 slide in the spacing groove 10 of axial spout 9 one side through rotatory pull rod 1, realizes that fixture block 11 and drawing hammer 2 carry out the axial spacing to it is spacing to realize pull rod 1 and drawing hammer 2 axial, realizes pull rod 1 and drawing hammer 2 quick positioning, and the equipment is quick.
The drawing hammer 2 is of a cylinder structure, and the sleeve hole 8 penetrates through two ends of the cylinder structure. A plurality of clamping blocks 11 are distributed on the pull rod 1 along the axial direction, and the pull rod 1 and the drawing hammer 2 are positioned by clamping two adjacent clamping blocks 11 with a limiting groove 10 in the drawing hammer 2; when the position of the drawing hammer 2 on the pull rod 1 needs to be adjusted, only two clamping blocks 11 at proper positions need to be rotated to be clamped with the limiting groove 10 in the drawing hammer 2, and the adjustment is convenient, so that the drawing hammer is suitable for different use environments.
The working principle is as follows: when the rotary joint 12 needs to be maintained, the end cover screw of the rotary joint is unscrewed, the connecting disc 4 is screwed on the end surface of the rotary joint 12 through the bolt, the drawing hammer 2 is pulled upwards, and the rotary joint 12 is taken out under the action of force; the rotary joint 12 can be quickly disassembled and assembled without disassembling the spindle motor in a narrow space by using the rotary joint quick disassembling tool to be matched with the puller for disassembling.
