Description
Technical field
The utility model is related to field of mechanical technique, especially a kind of leading screw axial clearance adjusting mechanism.
Background technology
The precision of lead screw determines the precision of entire machine, and movement velocity is faster, and its precision effect is more notable.Such as without appropriate
Leading screw axial clearance adjusting mechanism, play drops lead screw simultaneously to influence performance and the service life of lead screw in an axial direction after assembly
The precision of low entire machine.The current patent in relation to leading screw axial clearance adjusting mechanism is less, in order to overcome the prior art to exist
Deficiency, solve problems of the prior art, a kind of leading screw axial clearance adjusting mechanism is provided.
Invention content
Technical problem to be solved in the utility model is：It is simple in structure to provide one kind, is easily installed and dismantles, improves silk
The leading screw axial clearance adjusting mechanism of the performance of bar and service life and complete machine precision, with overcome the deficiencies in the prior art.
The utility model is realized in this way：
One end of a kind of leading screw axial clearance adjusting mechanism, including placed seat, lead screw is inserted into placed seat and is fixed, and is pacifying
It puts and taper faying face is set in seat, clamp spring mounting groove is set in the placed seat above taper faying face, under clasp nut, spring
Baffle, spring, spring overhead gage and clamp spring sequentially pass through lead screw and are caught in placed seat, wherein the setting of clasp nut lower end and cone
The taper faying face one that shape faying face matches, and the internal thread that setting matches with lead screw in the clasp nut, spring lower block
Plate is close to the upper surface of clasp nut, and clamp spring is close to spring overhead gage and the clamp spring is caught in clamp spring mounting groove, which is located at
Between spring lower baffle plate and spring overhead gage and pre-tighten.
By adopting the above-described technical solution, compared with prior art, in use, lead screw is passed through to the through-hole of placed seat,
Taper faying face on clasp nut is in close contact with the taper faying face in placed seat, the screw thread of clasp nut screw thread and lead screw
At a fully engaged, spring lower baffle plate, which is placed in, to be closed on nut upper surface, and spring is placed between spring lower baffle plate and spring overhead gage,
Clamp spring is placed in the clamp spring mounting groove in placed seat, and when the assembly is complete, spring is in compressed state.It is suitable by installing
Spring stiffness coefficient, play the role of adjust lead screw axial gap, eliminate axial float, when machine using a period of time
The axial gap generated afterwards can also be adjusted by the spring in mechanism, to extend the service life and essence of entire machine
Degree.Compared with prior art, this technology not only reasonable design, it is simple in structure, easy to assemble, adaptable etc., and can eliminate
Axial float, the advantages that extending the service life and precision of entire machine.
Description of the drawings
Attached drawing 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The embodiments of the present invention：A kind of leading screw axial clearance adjusting mechanism, as shown in the picture, including placed seat 1, silk
In placed seat 1 and fixed, setting taper faying face 2, the peace above taper faying face 2 in placed seat 1 are inserted into one end of bar 7
Setting clamp spring mounting groove 3 in seat 1 is put, clasp nut 4, spring lower baffle plate 5, spring 9, spring overhead gage 6 and clamp spring 8 sequentially pass through
Lead screw 7 is simultaneously caught in placed seat 1, the taper faying face one that wherein setting of 4 lower end of clasp nut matches with taper faying face 2
11, and the internal thread 10 that setting matches with lead screw 7 in the clasp nut 4, spring lower baffle plate 5 are close to the upper table of clasp nut 4
Face, clamp spring 8 is close to spring overhead gage 6 and the clamp spring 8 is caught in clamp spring mounting groove 3, which is located at spring lower baffle plate 5 and bullet
Between spring overhead gage 6 and pre-tighten.
The description of said program is the utility model being intended to facilitate those of ordinary skill in the art to understand and use,
Person skilled in the art obviously easily can make various modifications to embodiment, and therefore, the utility model is unlimited
In above-mentioned real scheme, those skilled in the art's method according to the present utility model does not depart from what the utility model scope was made
It improves and modification should be all within the protection scope of the utility model.
