Abstract
The utility model discloses a rail clamping device, which comprises a screw (1) and a rail clamping base (10), wherein a nut (3) is arranged at the top of the screw (1), and the screw (1) below the nut (3) is sleeved with a hinged support; the outer side of the upper half part of the screw (1) is coated with a spring (5), and the spring (5) is located below the hinged support (2); both sides of the hinged support (2) are symmetrically connected with connecting rods (4), and the connecting rods (4) are respectively connected with a clamping bar (6); each of the clamping bars (6) is provided with a through hole (61), and the clamping bars (6) are fixed on the rail clamping base (10) in the through hole (61) through a pin shaft; and jaws (7) are arranged on the tail ends of the clamping bars (6). According to the utility model, a cold sawing machine is instantly driven during running, and the application range of the cold sawing machine is expanded.
Description
Technical field
The utility model relates to a kind of device on the cold saw track, especially relates to a kind of rail clamping device.
Background technology
Do not have brake apparatus on traditional cold saw track, if will make cold sawing machine stop to move ahead, can only slow down gradually, can not reach the immediately effect of braking, therefore need the immediately occasion of braking in some occasions, cold sawing machine has produced limitation.
The utility model content
The utility model does not have brake apparatus in order to solve on the present cold sawing machine, the problem that is difficult to brake immediately provides a kind of rail clamping device for this reason, comprises screw rod 1 and folder flange of rail seat 10, the top of described screw rod 1 is provided with a nut 3, and cover has a free bearing 2 on the screw rod 1 of nut 3 belows; The first half outside of described screw rod 1 is enclosed with spring 5, and described spring 5 is positioned at the below of free bearing 2; The bilateral symmetry of described free bearing 2 is connected with a connecting rod 4, is connected with respectively a clamping bar 6 on described two connecting rods 4; Have a through hole 61 on the described clamping bar 6, by bearing pin clamping bar 6 is fixed on the folder flange of rail seat 10 in the described through hole 61; The end of described clamping bar 6 is provided with jaw 7.
The utility model rail clamping device, described free bearing 2 comprises the sleeve 21 that is enclosed within on the screw rod 1, described sleeve 21 outsides are symmetrically arranged with two projections 22, are respectively equipped with a hole 23 in described two projections 22.
The utility model rail clamping device, described two clamping bar 6 full symmetrics.
The utility model rail clamping device, described free bearing 2 and connecting rod 4 all connect by pin between connecting rod 4 and the clamping bar 6.
Operation principle of the present utility model: because clamping bar is fixed on the folder flange of rail seat by pin, as fulcrum, after nut has been twisted, spring is with free bearing jack-up, then the distance between two connecting rods shortens, both the distance between two clamping bar tops shortened, and the distance between two clamping bar ends just becomes large immediately, and this moment, rail clamping device was releasing orientation; Otherwise after nut was backed out, the distance between two clamping bar tops was elongated, and the distance between two clamping bar ends just diminishes immediately, and this moment, rail clamping device was for packing tightly state.
The beneficial effects of the utility model are:
The utility model can carry out to cold sawing machine under steam the moment braking, has enlarged the scope of application of cold sawing machine.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of free bearing in the utility model.
The specific embodiment
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
Rail clamping device as shown in Figure 1 comprises screw rod 1 and folder flange of rail seat 10, and the top of described screw rod 1 is provided with a nut 3, and cover has a free bearing 2 on the screw rod 1 of nut 3 belows; The first half outside of described screw rod 1 is enclosed with spring 5, and described spring 5 is positioned at the below of free bearing 2; The bilateral symmetry of described free bearing 2 is connected with a connecting rod 4, is connected with respectively a clamping bar 6 on the described connecting rod 4; Have a through hole 61 on the described clamping bar 6, by bearing pin clamping bar 6 is fixed on the folder flange of rail seat 10 in the described through hole 61; The end of described clamping bar 6 is provided with jaw 7, described two clamping bar 6 full symmetrics.Described free bearing 2 and connecting rod 4 all connect by pin between connecting rod 4 and the clamping bar 6.
Free bearing as shown in Figure 2 comprises the sleeve 21 that is enclosed within on the screw rod 1, and described sleeve 21 outsides are symmetrically arranged with two projections 22, is respectively equipped with a hole 23 in described two projections 22.
Operation principle of the present utility model: because clamping bar is fixed on the folder flange of rail seat by pin, as fulcrum, after nut has been twisted, spring is with free bearing jack-up, then the distance between two connecting rods shortens, both the distance between two clamping bar tops shortened, and the distance between two clamping bar ends just becomes large immediately, and this moment, rail clamping device was releasing orientation; Otherwise after nut was backed out, the distance between two clamping bar tops was elongated, and the distance between two clamping bar ends just diminishes immediately, and this moment, rail clamping device was for packing tightly state.
The utility model can carry out to cold sawing machine under steam the moment braking, has enlarged the scope of application of cold sawing machine.
The utility model is not limited to the aforesaid specific embodiment.The utility model expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
