Specific embodiment
In order to enable those skilled in the art to better understand the technical solutions of the present invention, with reference to the accompanying drawing and pass through
Specific embodiment further illustrates the technical solution of the utility model.
A kind of cylinder body fixture is provided in the present embodiment, which can clamp cylinder body 4 in bottom, and right
For the cylinder body 4 of different model, shared purpose can be realized, to not need to replace repeatedly when processing cylinder body 4 single
The corresponding fixture of model cylinder body 4.
As shown in Figure 1-3, the cylinder body fixture includes pedestal 1, tension assembly 2 and pushing mechanism 3, wherein tension assembly 2
It is arranged on pedestal 1, tension assembly 2 includes the sleeve 21 that can extend into cylinder body 4, tensioning ball 22 and nutted rod 23, sleeve 21
It is arranged on pedestal 1, is provided with multiple through-holes 211 in 21 side wall circumferential direction of sleeve, and is provided with one in each through-hole 211
Tight ball 22, nutted rod 23 are protruded into sleeve 21 and can be moved axially in sleeve 21 along nutted rod 23, and tensioning ball 22 is located at set
Between cylinder 21 and nutted rod 23, when nutted rod 23 moves axially, 23 periphery of nutted rod pushes tensioning ball 22 to lean out through-hole 211 and is used for
Cylinder body 4 is clamped or the release tensioning ball 22 of nutted rod 23 is used to discharge cylinder body 4；Pushing mechanism 3 is set to the bottom of pedestal 1,
Pushing mechanism 3 connect with nutted rod 23 and nutted rod 23 can be pushed to move axially.And it is tensioned ball in order to prevent out of sleeve 21
It rolls out, above-mentioned 211 diameter of through-hole is less than tensioning 22 diameter of ball.
When sleeve 21 is located in cylinder body 4, the inner sidewall for the second mounting hole 41 being arranged on through-hole 211 and 4 bottom of cylinder body
It is oppositely arranged, and is tensioned ball 22 and is then abutted under the promotion of nutted rod 23 with the inner sidewall of the second mounting hole 41, and then realize cylinder
The clamping of body 4.
As shown in Fig. 2, in order to guarantee that nutted rod 23 moves axially in pedestal 1 and the sleeve 21 being arranged on pedestal 1, this
The first mounting hole 111 is provided in embodiment on pedestal 1, sleeve 21 is connected to the first mounting hole 111.It wears 23 one end of nutted rod
The first mounting hole 111 is crossed, the other end not passed through is connect with pushing mechanism 3.It should be noted that above-mentioned pushing mechanism 3 is gas
Cylinder, pushing mechanism 3 can be electric putter in other embodiments.
Above-mentioned tensioning ball 22 includes sphere and the rubber layer being coated on the outside of sphere, this kind is tensioned ball and cylinder body inner sidewall
Between frictional force can get a promotion, effectively prevent about 4 play of cylinder body.Since tensioning ball surface is rubber layer, filling
When card cylinder body, it can prevent from scratching between tensioning ball and cylinder body, protect cylinder body inner sidewall.
As shown in figure 3, be provided on nutted rod 23 accommodate tensioning ball 22 groove 231,231 longitudinal section of groove be it is trapezoidal,
And the big end of groove 231 is close to cylinder body 4, so that nutted rod 23 clamps cylinder body 4 when pushing, when nutted rod 23 retracts in situ,
Cylinder body 4 is released.
For the ease of the positioning of cylinder body 4, multiple dowel hole (not shown)s are additionally provided on pedestal 1.Different model
The specific location of cylinder body 4, dowel hole is also different, and multiple dowel hole (not shown)s, which are arranged, can be satisfied different model
The positioning requirements of cylinder body 4.
