Abstract
The utility model relates to a vehicle window lifter fixing base press in nut's connection structure adopts the round nut to rivet with this body pressure of fixing base and is connected, can not lead to the fact the screw damage during riveting, bears high radial rotatory torsion when the bolt screw in can be guaranteed to its shape, improves production efficiency, reduces the energy consumption, promotes operator operation environment.
Description
Technical field
The utility model relates to the syndeton that vehicle window rises device holder, specifically a kind of syndeton of window regulator holder self-clinching nut.
Background technology
In existing window regulator, holder is as critical piece, wherein holder is provided with some attaching nuts, and existing domestic what generally adopt is bruising welding procedure, and connected by this part of nut holder, the shortcoming that this technique in use exists at present has:
(1) electric spark produced in bruising weldering process, can cause the obvious ablation vestige of plate surface, affect product appearance quality;
(2) because leg height is different, face of weld has the reasons such as greasy dirt in bruising welding process, easily produce electric spark and cause screw thread to damage;
(3) electrode welder is due under being in high temperature, hyperbaric environment for a long time, quick abrasion, causes nut to be located inaccurate, easily departs from welding position, cause installation dimension deviation;
(4) because current domestic multi-head welder technology is immature and equipment investment cost is large, therefore adopt one head arc welding machine more, can only single-point bruising welding, production efficiency is low, and when a product has multiple nut, needs repeatedly bruising welding, is difficult to guarantee dimensional tolerance;
(5) voltage pulsation that during welding, welding machine produces, be difficult to the intensity ensureing welding, and detection degree is high, is difficult to find and investigates, and can only carry out destructive testing;
(6) welder power is large, causes energy waste, easily produces spark and a large amount of smog in welding process, has a great impact the safety of operating personnel and working environment.
Utility model content
The purpose of this utility model is the syndeton providing a kind of window regulator holder self-clinching nut, adopt round nut to press with holder body to be connected, screw thread can not be caused during riveted joint to damage, high radial rotary torsion is born when its shape can guarantee that bolt screws in, enhance productivity, reduce energy consumption, promote operator operating environment.
For achieving the above object by the following technical solutions:
A kind of syndeton of window regulator holder self-clinching nut, comprise holder body, described holder body is provided with several nut installing holes, it is characterized in that: nut installing hole place of institute is provided with round nut, top or the bottom outer-edge place of round nut are provided with circular groove, a circle profile of tooth anti-rotation step is also provided with between arc groove and round nut outer wall, the external diameter of profile of tooth anti-rotation step is greater than the external diameter of arc groove and is less than the external diameter of round nut, described nut installing hole cross section is ledge structure, internal diameter and the circular groove of nut installing hole bottom match, the internal diameter on nut installing hole top and profile of tooth anti-rotation step interference fit.
Advantage of the present utility model:
(1) there is not rivet deformation in round nut in riveting process, can not cause damage to the screw thread of nut;
(2) the radial rotary torsion born when the profile of tooth anti-rotation step of round nut can ensure that bolt screws in after staking;
(3) adopt fixture location, can rivet by multiple nut simultaneously, not only increase production efficiency, and relative position size can be guaranteed;
(4) adopt pneumohydraulic pressure-cylinder to rivet, the safety of operator and operating environment are significantly promoted, also can reduce the power consumption of about 80%;
(5) arc groove of round nut can increase riveting intensity, the intensity after riveted joint, can be determined, do not need destructive testing by outward appearance, has big advantages to the process quality control of batch production.

Fig. 2 is the sectional view of the utility model round nut;
Fig. 3 is the upward view of the utility model round nut;
Fig. 4 is the internal construction schematic diagram of the utility model round nut and holder body fits.
Detailed description of the invention
As Figure 1-4, a kind of syndeton of window regulator holder self-clinching nut, comprise holder body 5, described holder body 5 is provided with several nut installing holes 51, it is characterized in that: nut installing hole 51 place of institute is provided with round nut 1, top or the bottom outer-edge place of round nut 1 are provided with circular groove 2, a circle profile of tooth anti-rotation step 3 is also provided with between arc groove 2 and round nut outer wall, the external diameter of profile of tooth anti-rotation step 3 is greater than the external diameter of arc groove and is less than the external diameter of round nut 1, described nut installing hole 51 cross section is ledge structure, internal diameter and the circular groove 2 of nut installing hole 51 bottom match, the internal diameter on nut installing hole 51 top and profile of tooth anti-rotation step 3 interference fit.
Profile of tooth anti-rotation step 3 and the inwall interference fit on nut installing hole 51 top of the utility model round nut, when round nut and holder body 5 press, make nut be in center, and have good locating effect; Round nut top or bottom outer-edge place arrange arc groove 2, and the excess stock produced when nut and holder body are riveted enters groove, both prevents sheet deformation, and adds riveting intensity simultaneously.
