Description
Technical field
The utility model is related to a kind of positioning fixtures, specifically, are related to a kind of contact switch lever shaft positioning fixture.
Background technology
Contact switch is widely used in the connection circuit of various mechanical actions, it is desirable that after lever shaft installation, in lever shaft
The line of centres of two mounting holes is at 60 ° on heart line and contact switch.Current installation method is that lever shaft is first sleeved on contact
On switch shaft, with bevel protractor by lever shaft be adjusted to need angle position, then with pressing plate from top by lever shaft compression, so
Afterwards positioning pin is finally stamped with dowel hole is bored on lever shaft and contact switch shaft.
Since the clamping mode of pressing plate is easy that lever shaft is made to rotate in drill-through journey, and bevel protractor positioning is not accurate enough,
Lever shaft installation site is not easy to ensure so that design requirement is not achieved in the lever shaft position after installation, and product qualification rate is low.
Utility model content
The technical issues of the utility model is solved is to provide a kind of contact switch lever shaft positioning fixture, can make lever
Axis positioning is easier, improves production efficiency.
Technical solution is as follows：
A kind of contact switch lever shaft positioning fixture, including pedestal, pillar, pressing plate, knurled nut, straight pin, chamfered edge pin,
Baffle；The bottom of baffle is connected to the top of pedestal, and baffle is provided with threaded hole, and pedestal is provided with straight pin through-hole and chamfered edge pin is logical
Hole；The outer wall of pillar is provided with connection external screw thread, and pillar one end is connected on threaded hole；Pressing plate is provided with fixed hole, pressing plate profit
It is sleeved on pillar with fixed hole, knurled nut is mounted on pillar, and positioned at the outside of pressing plate；Straight pin, chamfered edge pin point
It An Zhuan not be in straight pin through-hole and chamfered edge pin through-hole.
Further：It is provided with anti-skid chequer on the outer wall of knurled nut.
Compared with prior art, the utility model technique effect includes：All kinds of touching with lever shaft can be widely used in
The installation of point switch keeps lever shaft installation easier, and ensures that installation site meets design requirement, improves production efficiency.
1, the positioning method being combined with chamfered edge pin using straight pin, effectively prevent positioning, and product is facilitated to install.
2, the structure design of pedestal overhead gage can ensure the status requirement after lever shaft installation.
3, using knurled nut and pressing plate from side by lever shaft compression, ensure enough clamping forces, make lever shaft with
It will not be rotated during brill.
Description of the drawings
Fig. 1 is the usage state diagram of contact switch lever shaft positioning fixture in the utility model；
Fig. 2 is the vertical view of Fig. 1 in the utility model.
Specific implementation mode
It elaborates to technical solutions of the utility model below with reference to example embodiment.However, example embodiment
It can implement in a variety of forms, and be not understood as limited to embodiment set forth herein；On the contrary, providing these embodiments
So that the utility model is more comprehensively and completely, and the design of example embodiment is comprehensively communicated to those skilled in the art
Member.
As shown in Figure 1, being the usage state diagram of contact switch lever shaft positioning fixture in the utility model；As shown in Fig. 2,
It is the vertical view of Fig. 1 in the utility model.
Contact switch lever shaft positioning fixture, structure include：Pedestal 1, pillar 2, pressing plate 3, knurled nut 4, straight pin
5, chamfered edge pin 6, baffle 7；The bottom of baffle 7 is connected to the top of pedestal 1, and baffle 7 is provided with threaded hole, and pedestal 1 is provided with straight pin
Through-hole and chamfered edge pin through-hole；The outer wall of pillar 2 is provided with connection external screw thread, and 2 one end of pillar is connected on threaded hole；Pressing plate 3 is opened
There are fixed hole, pressing plate 3 to be sleeved on pillar 2 using fixed hole, knurled nut 4 is mounted on pillar 2, and is located at pressing plate 3
Outside.Straight pin 5, chamfered edge pin 6 are separately mounted in straight pin through-hole and chamfered edge pin through-hole.
Straight pin 5, chamfered edge pin 6 on pedestal 1 form position portion together；Pillar 2, pressing plate 3, knurled nut 4, baffle 7
Clamping part is formed together.It is provided with anti-skid chequer on the outer wall of knurled nut 4.
When installation, contact switch is attached to the lower section of pedestal 1, is positioned with straight pin 5, chamfered edge pin 6, then contact is opened
The lever shaft shut is gone to be affixed with the baffle 7 on pedestal 1, then tightens knurled nut 4, pressing plate 3 is made to be pressed on lever shaft
On baffle 7, then positioning pin is finally stamped, lever shaft is completed with dowel hole is bored on lever shaft and contact switch shaft
Installation.
Term used in the utility model is explanation and term exemplary, and not restrictive.Due to the utility model energy
The enough spirit or essence being embodied in a variety of forms without departing from utility model, it should therefore be appreciated that above-described embodiment is unlimited
It in any details above-mentioned, and should widely be explained in the spirit and scope defined by appended claims, therefore fall into power
Whole variations and remodeling in profit requirement or its equivalent scope all should be appended claims and covered.
