Abstract
The utility model provides an improved structure of a press roll cylinder. The improved structure comprises a cylinder body, a piston and a piston rod extending downward and is characterized in that a screwed hole which is coaxial with the piston rod is arranged at the top of the cylinder body, a gland is connected onto the cylinder through the screwed hole, the gland and the cylinder body are sealed through a seal ring, a screwing portion is installed on the outer side surface of the gland, and another screwing portion is installed at the upper end of the piston rod. When the piston rod is needed to be connected with or detached from a press roll seat, a tool (wrench, screw driver and the like) is used for detaching the gland, so that the tool can be inserted from the screwed hole at the upper end of the cylinder body and can directly rotate the piston rod through the screwing portion of the piston rod, and the detachment of the piston rod from the press roll seat is completed. According to the structure of the improved structure, installation and detachment are facilitated, length of an extending end can be reduced because process of an operation flat portion at the extending end of the piston rod is not needed, and installation height of the cylinder can be reduced.
Description
Technical field
The utility model relates to a kind of air cylinder structure, employed pressure roller air cylinder structure in particularly a kind of glass tempering equipment.
Background technology
On single curved surface moulding tempering apparatus, a lot of pressure rollers are housed, to improve the precision of glass ware forming.Said pressure roller is contained on two roller seats, and said pressure roller is being connected with the pressure roller cylinder, with the knee-action of control pressure roller.
Existing pressure roller cylinder, as shown in Figure 1, it is flat (shown in the h of Fig. 1, being at least 5mm) that one section h is arranged on the external part of piston rod, blocks this flat rotation for spanner, and piston rod is connected with roller seat.Because the mounting structure of roller seat and pressure roller cylinder is compact, the operating space is little, and this mounting means is also inconvenient, is not easy also to guarantee that mounting height is consistent, and dismounting is just more difficult, the adjacent a lot of member of need dismantling.On the other hand, also require pressure roller cylinder mounting height little on the function, and, pressure roller cylinder mounting height can't be reduced owing on existing piston rod, will have an operation flat.
Summary of the invention
The purpose of the utility model is to address the above problem, and a kind of improvement structure of pressure roller cylinder is provided, and it is simple in structure, and is easy for installation, can reduce the cylinder mounting height.
The purpose of the utility model realizes through following technical scheme.
A kind of improvement structure of pressure roller cylinder; The piston rod that it comprises cylinder body, piston and stretches out down; It is characterized in that: be provided with at the top of said cylinder body and the co-axial threaded hole of said piston rod, a gland is connected on the said cylinder body through said threaded hole, seals with sealing-ring between said gland and the said cylinder body; On the outer side of said gland, be provided with the portion of turning, also be provided with the portion of turning in the upper end of said piston rod.
In preferable technical scheme: the portion of turning of said gland is flat recess, cross recess, outer-hexagonal post or inner hexagonal hole.
In preferable technical scheme: the portion of turning of said piston rod is flat recess, cross recess, outer-hexagonal post or inner hexagonal hole.
Compared with prior art; Adopt the advantage that the utlity model has of technique scheme to be: the structure that adopts the utility model to provide; Not only convenient the installation and dismounting, and, since need be on the piston rod external part process operation flat; The length of external part can reduce, and can reduce the cylinder mounting height.
Description of drawings
Fig. 1 is the structural representation of existing pressure roller cylinder;
Fig. 2 is the structural representation of pressure roller cylinder provided by the invention;
Fig. 3 A, Fig. 3 B, Fig. 3 C, Fig. 3 D are respectively the structural representations of the portion that turns of gland and piston rod.
Embodiment
Like Fig. 2; The improvement structure of a kind of pressure roller cylinder that the utility model provides; The piston rod 5 that it comprises cylinder body 1, piston 6 and stretches out down; Be provided with 11, one glands 2 of said piston rod 5 co-axial threaded holes at the top of said cylinder body 1 and be connected on the said cylinder body 1 through said threaded hole 11, between said gland 2 and the said cylinder body 1 with sealing-ring 3 sealings; On the outer side of said gland 2, be provided with and make things convenient for instrument to carry out the portion that turns 21 of disassemble and assemble work; Shown in Fig. 3 A, Fig. 3 B, Fig. 3 C, Fig. 3 D, the portion that turns 21 optional flat recesses, cross recess, outer-hexagonal post or the inner hexagonal hole etc. of said gland 2, the upper end of said piston rod 5 also is provided with and makes things convenient for instrument to carry out the portion that turns 4 of disassemble and assemble work; Still shown in Fig. 3 A, Fig. 3 B, Fig. 3 C, Fig. 3 D, the also optional flat recess of the portion that turns 4 of said piston rod 5, cross recess, outer-hexagonal post or inner hexagonal hole etc.
Need piston rod 5 be connected with roller seat or when dismantling; Tool using (spanner or bottle opener etc.) is removed gland 2; Instrument just can insert from the threaded hole of cylinder body 1 upper end 11, and the portion that the turns 4 direct rotory piston bars 5 through piston rod 5, makes piston rod 5 and roller seat completion disassemble and assemble work.
The structure that adopts the utility model to provide, not only convenient the installation and dismounting, and, since need be on the piston rod external part process operation flat, the length of external part can reduce, and can reduce the cylinder mounting height.
More than explanation is just illustrative as far as the utility model; And nonrestrictive, those of ordinary skills understand, under the situation of spirit that does not break away from claim and limited and scope; Can make many modifications, variation or equivalence, but all will fall within the protection domain of the utility model.
