Description
Technical field
The utility model relates to a kind of cylinder, is specifically related to a kind of fastening type thin cylinder.
Background technique
Along with people are more and more higher to the requirement of mechanical automation, cylinder effect at work also seems especially important, traditional cylinder, not only thick but also heavy, volume is large, shared space is large, and operation precision is not high, working life is short, and present on the market some cylinders, its inner arrange reasonable not, complicated structure, performance is also stable not, can't well satisfy work requirements.For improving the deficiency of traditional cylinder, a kind of thin cylinder has appearred on market, and this cylinder is thin and light, and rational in infrastructure simple, the joint of all parts is provided with seal ring.Because the bonnet of cylinder is generally fixed, and the bonnet design class of this thin cylinder is similar to protecgulum, adopt the mounting type of flush type to be fixedly connected with cylinder body, its joint is provided with seal ring and jump ring, and installing is not still easily, complex structure, when piston movement and bonnet acutely clash into, this bonnet is not still very firm with being connected of cylinder body, has looseningly on jump ring, and situation may leak air.
The model utility content
For the deficiency that prior art exists, the utility model provides a kind of fastening type thin cylinder, and the bonnet of this fastening type thin cylinder is easy for installation, and is simple in structure, connects more firmly, and sealing reliability is strong.
For achieving the above object, the utility model provides following technological scheme: a kind of fastening type thin cylinder, comprise cylinder body, protecgulum, bonnet, piston rod and piston, described piston is adaptive to be arranged in cylinder body, sealed at both ends protecgulum and the bonnet of being fixed with of described cylinder body, described piston rod one end is positioned at outside cylinder body, and the piston in the other end and cylinder body is fixedly connected with, described cylinder body is provided with the bonnet joint groove that matches with bonnet, and described bonnet is by groove and cylinder body riveted joint.
By adopting technique scheme, the cylinder body of this fastening type thin cylinder is provided with the bonnet joint groove that matches with bonnet, after being embedded in cylinder body, bonnet is stuck in groove, by the hydraulic-pressure riveting press, bonnet is sticked in groove, make bonnet and cylinder body become an integral body, need not seal ring and be connected with jump ring and can closely connect, easy for installation, simple in structure, connect more firmly, sealing reliability is strong.
The utility model further is set to, and described bonnet is provided with annular chamfer with respect to the outer circular edge place of cylinder interior one side.
By adopting technique scheme, on bonnet, chamfering inner circle diameter dimension is fixedly connected with the internal diameter size of part with cylinder body less than bonnet, in the time of convenient the installation, bonnet can be aimed at cylinder body connection mouth place, and chamfering has also played a guidance quality effect simultaneously, makes bonnet can imbed more smoothly cylinder body.
The utility model further is set to, and the central position of corresponding chamfering one side of described bonnet is provided with the frustoconic shape groove, and the opposite side central position is provided with the frustoconic shape projection, and the greatest diametrical dimension of described frustoconic shape groove is less than the minimum diameter size of frustoconic shape projection.
By adopting technique scheme, integrated bonnet utilizes the shape and structure of groove and projection, in the situation that do not increase the compressive strength that bonnet thickness increases bonnet, saves material and cost.

Embodiment
Referring to figs. 1 through Fig. 5, the utility model fastening type thin cylinder embodiment is described further.
A kind of fastening type thin cylinder, comprise cylinder body 1, protecgulum 2, bonnet 3, piston rod 4 and piston 5, piston 5 is adaptive to be arranged in cylinder body 1, sealed at both ends protecgulum 2 and the bonnet 3 of being fixed with of cylinder body 1, piston rod 4 one ends are positioned at outside cylinder body 1, piston 5 in the other end and cylinder body 1 is fixedly connected with, and cylinder body 1 is provided with bonnet 3 joints the groove 9 that matches with bonnet 3, and bonnet 3 is riveted by groove 9 and cylinder body 1.
By adopting technique scheme,, the cylinder body 1 of this fastening type thin cylinder is provided with bonnet 3 joints the groove 9 that matches with bonnet 3, as shown in Figure 1, after being embedded in cylinder body 1, bonnet 3 is stuck in groove 9 places, by the hydraulic-pressure riveting press, bonnet 3 is sticked in groove 9, make bonnet 3 and cylinder body 1 become an integral body, need not seal ring and be connected with jump ring and can closely connect, easy for installation, simple in structure, connect more firmly, sealing reliability is strong.
