Abstract
The utility model relates to a spring prepressing combination structure for a pneumatic actuator. The spring prepressing combination structure for the pneumatic actuator comprises a support column and a barrel-shaped spring seat with an opened end and a closed end, wherein the support column and the end portion of the spring seat are connected in a fastening mode, the spring seat and a side wall of the support column are provided with annular bosses, and a compression spring is arranged between the opposite annular end faces of the two bosses. The spring prepressing combination structure has the advantages of being simple and high in assembling speed, improving the production efficiency and being suitable for being popularized and used.
Description
Technical field
The utility model relates to a kind of parts for pneumatic actuator, relates in particular to a kind of spring precompressed composite structure for pneumatic actuator.
Background technique
At present on the market, the spring fitting mode for pneumatic actuator mainly contains following two kinds:
One, assembles without precompressed: as shown in Figure 1, the spring that pinion and-rack is used for pneumatic actuator without the precompressed composite structure comprise cylinder body a, end cap b, with the piston c of tooth bar, with tooth bar meshed gears axle d and spring e, in order to satisfy spring e installation requirement, cylinder body a and end cap b must lengthen, the waste material, and assembling and dismounting spring easily cause end cap b to fly out during without the pneumatic actuator of precompressed composite structure, have potential safety hazard;
Two, precompressed assembling: such as the disclosed a kind of spring precompressed composite structure for pneumatic actuator of China Patent Publication No. CN101598231A, it adopts namely is as shown in Figure 2 precompressed assembling mode, comprise spring e, spring seat f and pillar g, but the riveted process of pillar g is complicated, length consuming time, inefficiency, and cost is high, and riveted is wayward, pillar g easily occurs bending and deformation, and causes catching phenomenon.
The model utility content
The purpose of this utility model is to provide a kind of spring precompressed composite structure for pneumatic actuator, to solve the problem that exists in the background technique.
To achieve these goals, the technological scheme that the utility model is used for the spring precompressed composite structure of pneumatic actuator is: a kind of spring precompressed composite structure for pneumatic actuator, the tubular spring seat that comprises the sealing of pillar and an end opening one end, described pillar is that seizing type is connected with the end of spring seat, be equipped with annular boss on the sidewall of described spring seat and pillar, be provided with Compress Spring between the relative annular end face of two boss.The mentality of designing of this technological scheme is: be designed to spring seat and be connected with the pillar seizing type and with the spring precompressed betwixt, compare with the riveted precompressed, simple in structure, assembling speed is fast, has improved manufacturing efficiency.
As preferably, the Closed End of described spring seat is provided with through hole, and the diameter of through hole and pillar is adaptive, and an end face of described pillar is provided with groove, and the two ends of groove extend to the pillar sidewall always and form two shell fragments, and the end of two shell fragments has outward extending flange.During assembling, the end with shell fragment of pillar is inserted in the through hole of spring seat, the flange of shell fragment meeting back-off is lived spring seat and can not deviate from.
As preferably, the outboard end edge of through hole all has chamfering on the end of described shell fragment and the spring seat Closed End.Chamfering can realize the plug of pillar smoothly, can avoid again pillar by the wedge angle scratch simultaneously.
The beneficial effect that the utility model is used for the spring precompressed composite structure of pneumatic actuator is: simple in structure, assembling speed is fast, has improved manufacturing efficiency, and cost is low.
Description of drawings
Fig. 1 is that the spring of prior art pneumatic actuator is without a kind of structural representation of precompressed assembling;
Fig. 2 is a kind of structural representation of the spring precompressed composite structure of prior art pneumatic actuator;
Fig. 3 is a kind of structural representation of the utility model spring precompressed composite structure;
Fig. 4 is the structural representation that the utility model spring precompressed composite structure is applied to the pinion and-rack pneumatic actuator;
Fig. 5 is the structural representation that the utility model spring precompressed composite structure is applied to shift fork type pneumatic actuator.
Number in the figure is respectively: 1. pillar 2. spring seats 3. shell fragments 4. Compress Springs 5. pinion and-rack pneumatic actuators 6. shift fork type pneumatic actuators.
Embodiment
Also by reference to the accompanying drawings the technical solution of the utility model is further described specifically below by embodiment.
Embodiment:
A kind of spring precompressed composite structure for pneumatic actuator, as shown in Figure 3, comprise pillar 1 and spring seat 2 that seizing type connects, spring seat 2 is the tubular structure of an end opening one end sealing, outer wall at its opening end has annular boss, Closed End at spring seat 2 has through hole, the outboard end edge of through hole has chamfering, one end face of described pillar 1 has groove, the two ends of groove extend to pillar 1 sidewall always and form two shell fragments 3, the end of two shell fragments 3 has outward extending flange, the outboard end edge of the end of described shell fragment 3 has chamfering, described pillar 1 is adaptive with the diameter of through hole, also has annular boss on the sidewall of described pillar 1, its with spring seat 2 on the two relative annular end face of boss between be provided with Compress Spring 4.
This spring precompressed composite structure is compared with the riveted precompressed with the spring precompressed betwixt, and simple in structure, assembling speed is fast, has improved manufacturing efficiency, can be used for polytype pneumatic actuator: as shown in Figure 4, be pinion and-rack pneumatic actuator 5; As shown in Figure 5, be shift fork type pneumatic actuator 6.
Above-mentioned described specific embodiment only is that the preferable examples explanation is done in design of the present utility model.All any modifications of making within spirit of the present utility model and principle or replenish or be equal to alternatively all should be included within the protection domain of the utility model claim.
