Abstract

The air spring hole machined protective tooling that the utility model relates to, be inserted in the first intercommunicating pore of sky spring hole and auxiliary air reservoir, protective tooling comprises cored screw, one end of cored screw is along the circumferential expanding head extending external diameter and be greater than the first intercommunicating pore internal diameter of its sidewall, one end of cored screw hangs over the first intercommunicating pore oral area by expanding head, and the body of rod of cored screw runs through whole auxiliary air reservoir and passes from the second intercommunicating pore of auxiliary air reservoir opposite side; This frock can guarantee that its foreign material such as cutting fluid and iron filings can not flow in air chamber when processing empty spring hole.

Description

Air spring hole machined protective tooling
Technical field
The utility model relates to a kind of protective tooling, is specifically a kind of air spring hole machined protective tooling.
Background technology
City rail vehicle bogie auxiliary air reservoir and empty spring are connected as a single entity, this is to increase empty spring volume, improve vehicle riding comfort, but its cutting fluid and iron filings can directly enter additive air indoor when processing empty spring hole, if there is the performance that the foreign material such as cutting fluid and iron filings can affect empty spring in auxiliary air reservoir, cotton is adopted to protect during current processing sky spring hole, but adopt cotton protection that sky spring hole bottom space can be caused too small, frequent shutdown cleaning iron filings in process, and cotton is rolled by iron filings in process, the decline of sky spring hole surface crudy and iron filings are made to enter additive air indoor and lose protective action, also chip can be caused to enter auxiliary air reservoir when taking out cotton.
Utility model content
Technical problem to be solved in the utility model is: overcome prior art Problems existing, provides a kind of air spring hole machined protective tooling, can guarantee that its foreign material such as cutting fluid and iron filings can not flow in air chamber when processing empty spring hole.
The technical scheme in the invention for solving the technical problem is as follows:
Air spring hole machined protective tooling, be inserted in the first intercommunicating pore of sky spring hole and auxiliary air reservoir, protective tooling comprises cored screw, one end of cored screw is along the circumferential expanding head extending external diameter and be greater than the first intercommunicating pore internal diameter of its sidewall, one end of cored screw hangs over the first intercommunicating pore oral area by expanding head, the body of rod of cored screw runs through whole auxiliary air reservoir and passes from the second intercommunicating pore of auxiliary air reservoir opposite side, during so empty spring hole machined, cutting fluid, chip and less iron filings directly flow out from cored screw endoporus, thus guarantee working (machining) efficiency, empty spring hole surface quality and additive air indoor seasoning there is no foreign matter.
The perfect further technical scheme of the utility model is as follows:
Preferably, on screw rod between expanding head and the first intercommunicating pore, cover has seal gasket, cored screw is bolted with the clamp nut that external diameter is greater than the second connecting hole internal diameter from one end that the second connecting hole passes, when clamp nut is tightened on the second intercommunicating pore oral area, seal gasket tamps between the space of cored screw and the first intercommunicating pore oral area, this is in order to further enhanced leaktightness performance, prevents foreign material from flowing into auxiliary air reservoir from the gap between the first connecting hole and screw rod.
Preferably, screw rod on the downside of seal gasket is bolted with the spigot nut that external diameter is identical with the first intercommunicating pore diameter, spigot nut is inserted in described first intercommunicating pore, the effect of spigot nut has two: one to be seal gasket upwards can be compressed, one is also had to be exactly location anti-rock effect, because the diameter of screw rod is less than the first intercommunicating pore, when screw rod is passed the second intercommunicating pore, easily wear askew, as long as spigot nut falls into the first intercommunicating pore to have had this spigot nut just can accomplish, the screw rod of its underpart must pass the second intercommunicating pore.
Preferred, the screw rod between clamp nut and the second connecting hole is socketed with pad, and pad can play anti-skidding fastening effect.
Preferably, also comprise importing bar, one end of described importing bar is screwed onto on the end face of described expanding head, because the diameter in empty spring hole is less than the exercisable space of staff, so when mounting tool, can hand-held importing bar, slowly put into by equipment, hand-held adjustment angle is also very convenient.
Preferred, the length importing bar is greater than the degree of depth in sky spring hole.
The utility model now adopts empty spring hole machined protective tooling, when can guarantee sky spring hole machined, auxiliary air reservoir foreign enters, and this protective tooling structure is simple, and application is convenient, improve working (machining) efficiency and ensure crudy, can apply on the rail vehicle truck of other similar structures widely.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present utility model.
In figure: cored screw 1, rubber blanket 2, spigot nut 3, pad 4, clamp nut 5, importing bar 6.
Detailed description of the invention
With reference to the accompanying drawings and the utility model is described in further detail in conjunction with the embodiments.But the utility model is not limited to given example.
Embodiment 1
The air spring hole machined protective tooling that the present embodiment provides, as shown in Figure 1, first by cored screw 1, rubber blanket 2, spigot nut 3 is mounted with, importing screw rod 6 screws in the screw thread of cored screw expanding head end face, hand-held importing screw rod 6 protective tooling is put into sky spring hole and additive air is indoor, protective tooling is located to solve lower opening eccentricity issues on auxiliary air reservoir by guide-localization nut 3, assembling pad 4 and clamp nut 5, tightening clamp nut 5 makes rubber blanket 2 fit tightly with plane on auxiliary air reservoir, iron filings and cutting fluid is prevented to enter auxiliary air reservoir by rubber blanket, protective tooling has assembled button will import screw rod back-out.During empty spring hole machined, cutting fluid, chip and less iron filings flow out from cored screw endoporus, thus ensure that working (machining) efficiency, empty spring hole surface quality and additive air indoor seasoning there is no foreign matter.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
