Abstract
The utility model discloses an integrated type casing positioning device, belonging to the casing mounting technical field, which comprises a step positioning shaft on a bottom die of a rail plate, wherein the lower end of the positioning shaft is through the bottom die and fixed by a nut, the part of the positioning shaft abut against the upper plane of the bottom die is provided with an octagonal structure with knurl at outer side, the upper end of the positioning shaft is provided with a tightening structure, and the part of the positioning shaft between the upper end of the positioning shaft and the octagonal structure is a cone with a small upper and a large lower. The utility model is easy to install and demold, has simplified process and high production efficiency, which is suitable for producing the rail plate with a pre-embedded casing and especially for the condition with low tolerance of the pre-embedded casing.
Description
Technical field
The utility model relates to the fixture that is embedded in sleeve pipe wherein when a kind of track plate is made in advance.
Background technology
Existing cover pipe fixing device, all be to adopt the sleeve pipe bolt, be that the sleeve pipe bolt passes bed die from track plate bed die below, spin with the service sleeve that is positioned at the bed die top again, this just need dig foundation ditch in advance below bed die, the staff must install bolt from the foundation ditch that is arranged in the bed die below, install very inconveniently like this, and cause construction cost very high, simultaneously, must below track plate bed die, the sleeve pipe bolt removed earlier before the demoulding of track plate, after the demoulding of track plate, reinstall the sleeve pipe bolt again, make operation loaded down with trivial details, repeat, cause production efficiency low.
The utility model content
Based on the defective of prior art, the technical problems to be solved in the utility model is: provide a kind of being convenient to install, be convenient to the demoulding, operation is simplified greatly, the monoblock type casing location device that production efficiency is high.
The technical solution of the utility model is: a kind of monoblock type casing location device, comprise the stepped locating shaft that is loaded on the track plate bed die, the lower end of locating shaft is passed track plate bed die and is fixed by nut, locating shaft shaft part near plane on the track plate bed die is all directions structure that the outside is provided with annular knurl, the upper end of locating shaft has tightens structure, is up-small and down-big taper in the upper end of this locating shaft and the shaft part between the structure of all directions.
Describedly tighten the upper end that structure is locating shaft and adopt outer six sides or outer tetragonal.Each corner of being somebody's turn to do outer six sides or outer tetragonal is fillet, and the inwall of fillet and service sleeve is suitable.
The described locating shaft outside is socketed with service sleeve, and the service sleeve lower end is near plane on the track plate bed die, and seals by sealing ring between the contact-making surface on plane on service sleeve and the track plate bed die.
Plane and service sleeve contact position are provided with the annular recess that extends along service sleeve lower surface circumferencial direction on the described track plate bed die, and described sealing ring is loaded in the annular recess.
The beneficial effects of the utility model are: easy for installation, need not to remove this positioner during the demoulding, directly extract the track plate, the monoblock type casing location device still is installed on the track plate bed die, only needs new service sleeve is socketed in that swelling puts and can realize building of next track plate; Make the production process of track plate simplify, production efficiency improves greatly.
Below in conjunction with the drawings and specific embodiments the utility model is further specified.

The specific embodiment
Preferred embodiment
Extremely shown in Figure 5 as Fig. 1, a kind of monoblock type casing location device, comprise the stepped locating shaft 2 that is loaded on the track plate bed die 6, track plate bed die 6 and fixing by nut 5 is passed in the lower end of locating shaft 2, locating shaft 2 shaft parts near plane on the track plate bed die 6 are all directions structure 4 that the outside is provided with annular knurl 9, the upper end of locating shaft 2 is outer tetragonal 8, the outer tetragonal 8 of the upper end of this locating shaft 2 and from all directions the shaft part between the structure 4 be up-small and down-big taper 7; Locating shaft 2 outsides are socketed with service sleeve 1, and service sleeve 1 lower end is near plane on the track plate bed die 6, and on service sleeve 1 and the track plate bed die 6 between the contact-making surface on plane by sealing ring 3 sealings; Plane and service sleeve 1 contact position are provided with the annular recess 6-1 that extends along service sleeve 1 lower surface circumferencial direction on the described track plate bed die 6, and described sealing ring 3 is loaded among the annular recess 6-1.Each corner of outer tetragonal 8 is fillet 10, and fillet 10 is suitable with the inwall 11 of service sleeve 1.
Need to prove that the locating shaft in the present embodiment is taked overall structure, directly be connected with the service sleeve inwall that structure is very simple, and installation is also very convenient, cost of manufacture is also low, is suitable for the less situation of service sleeve tolerance.The outer tetragonal 8 of the upper end of last embodiment locating shaft 2 also can adopt outer hexagonal structure.
The elaboration that the foregoing description of the present utility model is detailed the specific embodiment of the present utility model; but the utility model is not limited to the above-mentioned specific embodiment, all can by those skilled in the art based on the thinkable technological improvement of the foregoing description institute all within protection domain of the present utility model.
