Description
Technical field
The present invention relates to a kind of assembling device of ball screw assembly,, specifically a kind of quick-fitting device of ball screw assembly.
Background technology
The assembling of ball screw assembly, is as an important step of lead screw pair, and its efficiency of assembling influences the production cycle of entire product greatly, and device used in traditional assembly method is seen Fig. 1 for the assembling auxiliary sleeve, and Fig. 1 is an assembling auxiliary sleeve.When assembling, utilize and should assemble auxiliary sleeve, be placed in the nut, as shown in Figure 2.Auxiliary sleeve 11 plays the effect of supporting steel ball 13 in nut 12, at this moment put into steel ball 13, and dial steel ball 13 with thin club, makes it to get in effective raceway 14 of nut 12.
The shortcoming of this assembly method is: the skills involved in the labour to the workman have very big requirement, owing to be the manual ball of dialling, assembling speed reduces greatly; And steel ball can only be installed a circulation at every turn when assembling, waste time and energy.
Summary of the invention
In order to overcome the problem that traditional assembly method exists; The quick-fitting device that the purpose of this invention is to provide a kind of ball screw assembly, adopts this quick-fitting device assembling simple, does not need the operator of high professional qualification to accomplish; Improve efficiency of assembling, alleviated labour intensity.
The objective of the invention is to realize through following technical scheme:
A kind of quick-fitting device of ball screw assembly; It is characterized in that: this quick-fitting device comprises cylindric bracing frame; Upper surface at cylindric bracing frame is provided with one group to the goal hole that extends below, and is provided with the spherical cavity that communicates with single goal hole in the side of cylindric bracing frame; The quantity of spherical cavity is identical with the quantity in goal hole; The degree of depth of effective circulation of nut is suitable in the position of said spherical cavity and the ball screw assembly.
Among the present invention, the quantity in said one group of goal hole is identical with effective loop number of nut.The quantity in said one group of goal hole is three, and effective loop number of nut is three.The diameter in said goal hole is more bigger than steel ball to be installed.
For ball can be flowed out smoothly, said goal hole is that arc transition is connected with spherical cavity.
The present invention is provided with the fixed-site step in the bottom of cylindric bracing frame, and nut sleeve is contained on the cylindric bracing frame in the ball screw assembly,, and this fixed-site step makes the degree of depth of effective circulation of position and nut of spherical cavity suitable.
For easy to assembly quick, the present invention also comprises assembly fixture, and this assembly fixture comprises push rod and pedestal, and one group is installed on the pedestal with the suitable push rod in goal hole, and the degree of depth of effective circulation of nut is suitable in the length of every push rod and the ball screw assembly.
Compared with prior art, the present invention assembles simply, does not need the operator of high professional qualification to accomplish, and has improved efficiency of assembling, has alleviated labour intensity; Owing to a plurality of circulations can be installed simultaneously, improve operating efficiency greatly.

The specific embodiment
A kind of quick-fitting device of ball screw assembly, of the present invention, with the inward turning ring nut of three circulations being arranged is that example is introduced.See Fig. 3, this quick-fitting device comprises cylindric bracing frame 1 and assembly fixture 5, is provided with one group three to the goal hole 2 that extends below at the upper surface of cylindric bracing frame 1, is provided with the spherical cavity 3 that communicates with single goal hole in the side of cylindric bracing frame 1; For steel ball 6 can be flowed out smoothly, goal hole 2 is connected for arc transition with spherical cavity 3.The diameter in goal hole 2 is more a little than the somewhat larger in diameter of steel ball 6 to be installed, greatly 0.5mm.The quantity in the quantity of spherical cavity 3 and goal hole 2 is identical also to be three.
Be provided with fixed-site step 4 in the bottom of cylindric bracing frame 1, nut 7 is sleeved on the cylindric bracing frame 1 in the ball screw assembly,, and this fixed-site step 4 makes the degree of depth of effective circulation of position and nut 7 of spherical cavity 3 suitable.
Fig. 4 is the structural representation of assembly fixture.Assembly fixture 5 comprises that 52, one groups of push rod 51 and pedestals are installed on the pedestal 52 with goal hole 2 suitable push rods 51, and the degree of depth of effective circulation of nut is suitable in the length of every push rod 51 and the ball screw assembly.
When adopting assembly fixture 5 to install, see Fig. 5.Because push rod 51 has certain toughness, its length is different in size simultaneously, just in time cooperates with spherical cavity 3.After steel ball 6 is installed by three goal hole 2 integral body, three push rods 51 of assembly fixture 5 are aimed at three goal holes 2, toward next pressure, ball just can be packed into rapidly in the nut 7 smoothly with assembly fixture 5.
Fig. 6 is a use sketch map of the present invention, and Fig. 7 is the cutaway view of Fig. 6.During assembling, nut 7 is sleeved on the quick-fitting device, an end of nut 7 is spacing by fixed-site step 4, then the degree of depth of each nut 7 effective circulation of the position alignment of spherical cavity 3.Hot-metal carburized steel ball 6 in 2 holes, goal hole, irritated steel ball 6 after, can adopt assembly fixture 5 to install.If, there is not suitable assembly fixture, also can use a plastics ear of maize to insert in this hole; Toward next pressure, steel ball 6 is flowed out by spherical cavity 3 then, because the degree of depth of effective circulation of nut 7 is suitable in the position of spherical cavity 3 and the ball screw assembly; Just can pack into smoothly rapidly nut 7 in, after steel ball 6 installations, again the present invention is rotated a certain angle; Forward in the end coil, steel ball 6 just can not run out along spherical cavity 3 more like this.
The present invention is easy to assembly fast, and does not need the operator of high professional qualification to accomplish, and has improved efficiency of assembling, has alleviated labour intensity.
