Description
Technical field
This utility model belongs to needle bearing technical field, and the needle roller of more particularly, to a kind of needle bearing is pressed into extrusion pressure
Test device.
Background technology
Whether the needle roller of existing test needle bearing snaps in qualified in retainer, need to load after retainer needle roller bearing
Load in plastic casing and rock, checked whether that needle roller drops.This technical scheme does not have concrete test data, the intensity rocked also because
People and different, make the power that needle roller drops out much due to cannot determine during transport, circulation, the knot of therefore uncontrollable retainer
Structure position and the maximum intensity force-applied in transport process of bearing.
Utility model content
The purpose of this utility model is to solve above-mentioned technical problem, and provides a kind of needle bearing test device, from
And realize testing the size that needle roller is pressed into extrusion pressure.In order to achieve the above object, technical solutions of the utility model are as follows：
Needle bearing test device, the side plate being vertically connected with described base including base；Described base is provided with leads
Rail, described guide rail is provided with the sliding part that can be moved along it, and described sliding part is provided with positioning seat, and described positioning seat is socketed with
Needle bearing, described needle bearing includes retainer, clamps some needle rollers in described retainer, and described positioning seat offers and institute
State the corresponding through hole of needle roller, described side plate is provided with the pressure head corresponding with described needle roller, described pressure head is by data wire even
It is connected to pressure transducer.
Specifically, connection wire rod nut body in described sliding part.
Specifically, described side plate is provided with screw rod, and described screw rod is electrically connected with motor.
Specifically, described pressure head is fixedly connected on described screw rod.
Specifically, described sliding part is provided with the opening corresponding with described through hole.
Compared with prior art, the having the advantages that of this utility model needle bearing test device：By pressure
, in retainer, pressure transducer detection pressing-in force is it may be determined that needle bearing is in automatic assembling fashionable dress needle force for head press-in needle roller
Size；Extrude needle roller by pressure head to drop retainer, pressure transducer detects extrusion pressure, can be to the aperture window dimension of retainer
It is adjusted, preventing from falling the phenomenon of pin during circulation, improving assembling quality, thus reducing the energy consumption of driving member.

Specific embodiment
Clear, complete description will be carried out to the technical scheme in this utility model embodiment below in conjunction with the accompanying drawings it is clear that
Described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.
Embodiment：
Shown in reference picture 1-5, the present embodiment is needle bearing test device, connects including base 1 is vertical with base 1 one end
The side plate 2 connecing；Base 1 is provided with guide rail 3, and guide rail 3 is provided with the sliding part 31 that can be moved along it, connection wire rod in sliding part 31
Nut body 32.
Sliding part 31 is provided with the positioning seat 33 of circle, and positioning seat 33 is provided with raised 34, raised 34 and can be socketed needle roller axle
Hold 4, needle bearing 4 includes retainer 41, clamps some needle rollers 42, positioning seat 33 offers relative with needle roller 42 in retainer 41
The through hole 5 answered, sliding part 31 is provided with the opening 51 corresponding with through hole 5.
Side plate 2 is provided with screw rod 21, and screw rod 21 is electrically connected with motor, and the bottom of screw rod 21 is connected with pressure head 22.Pressure head
22 configurations corresponding with needle roller 42, pressure head 22 is connected to pressure transducer 24 by data wire 23.
During application the present embodiment, after startup power supply, needle bearing 4 is placed on positioning seat 33 to position, needle roller puts into retainer
On 41 fenestra 43, make sliding part 31 mobile to pressure head 22 by leading screw and nut mechanism 32, motor rotates, screw rod 21 carries
Dynamic head 22 is descending, now the dress pin position be aligned pressure head 22 of retainer 41, when needle roller 42 is pressed in retainer 41, pressure head
22 transmit signal by data wire 23, and pressure transducer 24 detects pressing-in force；Equally, the needle bearing 4 installing is in positioning seat
On 33, pressure head 22 is descending to extrude retainer 41 to needle roller 42, and needle roller 42 drops out positioning seat 33 from through hole 5 and opening 51, now presses
Force transducer 24 detects extrusion pressure.The present embodiment can determine needle bearing 4 in automatic assembling fashionable dress according to detection pressing-in force
The size of needle force, detection extrusion pressure can be adjusted to fenestra 43 size of retainer 41, prevents from falling pin during circulation
Phenomenon, improve assembling quality, thus reducing the energy consumption of driving member.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of creating design without departing from this utility model, some deformation can also be made and improve, these broadly fall into this practicality
New protection domain.
