Technical Field
The utility model relates to the technical field of screw assembly, in particular to a screw stop ring assembly fixture.
Background
And after the nut rotates to one end of the screw rod, in order to prevent the nut from being separated from the screw rod, the moving position of the nut is limited by using a stop ring, the inner diameter of the stop ring is in interference fit with the outer diameter of the screw rod, and the stop ring and the screw rod are assembled through press fitting.
The existing stop ring assembly is that a worker holds the stop ring by hand to perform manual positioning, and then press-fitting is performed by using a sleeve. Because the inside of the stop ring is not of a symmetrical structure, the outside of the screw rod is consistent with the inside structure of the stop ring, and the screw rod has directivity, so that in the assembly process of the stop ring, the speed of manually positioning the stop ring by a worker is low, dislocation is easy to occur, the stop ring and the screw rod can be damaged, and potential safety hazards are caused.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a screw stop ring assembly fixture for solving the problems of low efficiency and easy dislocation in the assembly process of manually positioning a stop ring.
The technical scheme adopted for solving the technical problems is as follows:
the utility model provides a lead screw snap ring assembly fixture, includes base and moulding-die, the base on fixedly be provided with the boss, boss and the centre bore phase-match of lead screw for be in the base with the lead screw location on, the moulding-die in be provided with the axial lead screw axle chamber that runs through, the lower extreme of moulding-die be provided with shape and snap ring assorted constant head tank, the lower extreme of moulding-die fixedly be provided with and be used for adsorbing the magnet of snap ring.
Preferably, the outer side surface of the base is provided with a first section, the outer side surface of the pressing die is provided with a second section, and when the first section is vertically aligned with the second section, the stop ring is aligned with the direction of the screw rod.
Preferably, the magnet is located at the inner bottom of the positioning groove.
Preferably, the upper end face of the base is provided with a screw rod mounting groove, and the boss is positioned in the screw rod mounting groove.
Compared with the prior art, the utility model has the advantages that:
the die of the assembly fixture is designed according to the appearance characteristics of the stop ring, the die is tightly attached to the stop ring, the stop ring is prevented from shaking left and right, the stop ring is kept stable and is not inclined, the magnet arranged on the die can omit the operation of holding the stop ring by a worker, the stop ring cannot fall off when in suspension, the assembly efficiency can be improved, the scrapping of workpieces is reduced, and the loss is reduced.
Drawings
FIG. 1 is a schematic perspective view of the present utility model;
FIG. 2 is a schematic view of a die and stop ring of the present utility model;
FIG. 3 is a cross-sectional view of a stamper of the present utility model;
fig. 4 is a schematic perspective view of a base of the present utility model.
In the figure: 1. a base; 2. a magnet; 3. pressing; 4. a stop ring; 5. a boss; 6. a positioning groove; 7. cutting into a first section; 8. cutting the second dough; 9. a screw shaft cavity; 10. and a mounting groove.
Detailed Description
The utility model is described in further detail below with reference to the embodiments of the drawings.
As shown in the figure, the screw stop ring assembly fixture comprises a base 1 and a pressing die 3, wherein a boss 5 is fixedly arranged on the base 1, a screw mounting groove 10 is formed in the upper end face of the base 1, the boss 5 is positioned in the screw mounting groove 10, the boss 5 is matched with a central hole of a screw and used for positioning the screw on the base 1, and the screw mounting groove 10 enables the screw to be positioned on the base 1 more stably. The lead screw shaft cavity 9 which axially penetrates through the die 3 is arranged in the die 3, the positioning groove 6 which is matched with the stop ring 4 in shape is arranged at the lower end of the die 3, when the direction of the stop ring 4 is the same as that of the positioning groove 6, the stop ring 4 can be placed in the positioning groove 6, and the lead screw cannot enter when the direction is different, so that the lead screw shaft cavity is positioned, and the lead screw and the stop ring 4 are prevented from being damaged in the assembling process due to reverse direction and dislocation. The magnet 2 that is used for adsorbing the snap ring 4 is fixedly provided with in the lower extreme of moulding-die 3, and magnet 2 is located the interior bottom of constant head tank 6, and magnet 2 makes the frock have magnetism and firmly holds snap ring 4, makes snap ring 4 can not control rocking, and because the effect of magnetic attraction stops moving ring 4 can not take place to drop in unsettled pressure equipment in-process, therefore need not to support snap ring 4 in the pressure equipment in-process. The outer side face of the base 1 is provided with a first section 7, the outer side face of the pressing die 3 is provided with a second section 8, and when the first section 7 is vertically aligned with the second section 8, the stop ring 4 is aligned with the direction of the screw rod.
When the press fitting is carried out, the screw rod is firstly arranged on the base 1, the stop ring 4 is placed in the positioning groove 6 at the lower end of the press mold 3, the stop ring 4 is sucked, the first section 7 and the second section 8 are aligned to carry out directional positioning, then the lower end of the press mold 3 is sleeved at the upper end of the screw rod, the screw rod shaft at the upper end of the screw rod enters the screw rod shaft cavity 9 of the press mold 3, meanwhile, the stop ring 4 is sleeved on the screw rod shaft at the upper end of the screw rod, and in the process of pushing the press mold 3 downwards, the inner diameter of the stop ring 4 is in interference fit with the outer diameter of the screw rod shaft, and the press fitting of the stop ring 4 on the screw rod is completed under the action of thrust.
The scope of the present utility model includes, but is not limited to, the above embodiments, and any alterations, modifications, and improvements made by those skilled in the art are intended to fall within the scope of the utility model.
