Abstract
The utility model relates to a limiting structure of a movable working table; a track of the movable working table is provided with a roller wheel groove; a roller wheel of the movable working table is arranged in the roller wheel groove; the tail end of the roller wheel groove is provided with a limiting block higher than the roller wheel groove; the bottom of the roller wheel groove is provided with a through hole at the part close to the limiting block; a signal block is arranged in the through hole; the top of the signal block is exposed outside the bottom of the roller wheel groove; a signal block shaft which is arranged together with the signal block in a coaxial way and is integrated with the signal block is arranged under the signal block; a reset spring is sheathed on the signal block shaft, and is supported between the lower end surface of the signal block and the track of the movable working table; an approach switch used for sensing the action of the signal block shaft is arranged under the lower end surface of the signal block shaft. When the roller wheel of the movable working table reaches the position close to the limiting block, the signal block is firstly pressed by the roller wheel, the signal block is forced to move downwards together with the signal block shaft, and the approach switch can be used for controlling the movable working table to stop or go forward by a circuit when sensing the action of the signal block shaft.
Description
Technical field
The utility model relates to a kind of position limiting structure of travelling table, belongs to safety device for machine tools technical field.
Background technology
The travelling table below of lathe is often provided with roller, roller carries the weight of travelling table and moves along the roller groove on travelling table rail, travelling table is along with the scrolling realization of roller is advanced or retreats, travelling table arrives front must the parking of extreme position of stroke, otherwise easily causes damage even to lead to a disaster.
The travelling table using in prior art is spacing, and approach switch is placed on the left and right directions of travelling table rail, and user need widen rail groove in the time doing ground, and can not bind in rail groove top, approach switch is outside exposed, is easily touched misoperation, and very easily damages.
Utility model content
The purpose of this utility model is, overcomes problems of the prior art, and a kind of position limiting structure of travelling table is provided, simple in structure, not fragile and safe and reliable.
For solving above technical problem, the position limiting structure of a kind of travelling table provided by the utility model, travelling table rail is provided with roller groove, in described roller groove, carry travelling table roller, the end of described roller groove is provided with the limited block that exceeds roller groove, the bottom land of described roller groove is provided with through hole near the position of described limited block, in described through hole, block is installed, the bottom land of described roller groove is exposed on the top of described block, the below of described block is provided with and block coaxial line and the block axle that is connected as a single entity, on described block axle, be set with back-moving spring, described back-moving spring is supported between the lower surface and described travelling table rail of described block, the below, lower surface of described block axle is provided with the approach switch of induced signal piece axle action.
With respect to prior art, the utility model has been obtained following beneficial effect: in the time that travelling table roller arrives the position of close limited block, first idler wheel surface can be pressed onto block, force block to move down together with block axle, approach switch senses that the action of block axle halts by circuit control travelling table; In the time that travelling table roller leaves block, block again exposes roller groove under the tension force effect of back-moving spring; The whole induction installation of this system is positioned at travelling table rail below, is difficult for being damaged by collision.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, accompanying drawing only provides reference and explanation use, non-in order to limit the utility model.
Fig. 1 is the schematic diagram of the position limiting structure of the utility model travelling table.
In figure: 1. travelling table roller; 2. travelling table rail; 3. limited block; 4. block; 4a. block axle; 5. back-moving spring; 6. approach switch.
The specific embodiment
As shown in Figure 1, the position limiting structure of the utility model travelling table, travelling table rail 2 is provided with roller groove, in roller groove, carry travelling table roller 1, the end of roller groove is provided with the limited block 3 that exceeds roller groove, the bottom land of roller groove is provided with through hole near the position of limited block 3, block 4 is installed in through hole, the bottom land of roller groove is exposed on the top of block 4, the below of block 4 is provided with and block coaxial line and the block axle 4a that is connected as a single entity, on block axle 4a, be set with back-moving spring 5, back-moving spring 5 is supported between the lower surface and travelling table rail 2 of block 4, the below, lower surface of block axle 4a is provided with the approach switch 6 of induced signal piece axle action.
In the time that travelling table roller 1 arrives the position of close limited block 3, first idler wheel surface can be pressed onto block 4, force block 4 to move down together with block axle 4a, approach switch 6 senses that the action of block axle 4a halts by circuit control travelling table; In the time that travelling table roller 1 leaves block 4, block 4 again exposes roller groove under the tension force effect of back-moving spring 5.
The foregoing is only the better possible embodiments of the utility model, non-ly therefore limit to scope of patent protection of the present utility model.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 in the protection domain of the utility model requirement.
