Abstract
The utility model discloses a core shaft positioning protection device of an oil cylinder position sensor. The core shaft positioning protection device comprises a base and a supporting frame, wherein bolt holes and a core shaft sleeve groove are formed in the base; bolts penetrate through the bolt holes, so the base is fixedly connected with an end cover at one end of the sensor and sleeved on a core shaft through the core shaft sleeve groove; the supporting frame is arranged on the base; and grooves are formed at the upper end of the supporting frame and fixedly pressed against the bolts, and the shape of each groove is matched with that of each bolt on the end cover. In the replacement process of the sensor, the core shaft can be protected by the core shaft sleeve groove, and the problems of bending or damage of the core shaft caused by downward sliding of the sensor under the action of dead weight can be solved by using the supporting frame.
Description
Technical field
The utility model relates to position transducer, more particularly, relates to a kind of mandrel positioning protection device of oil cylinder position sensor.
Background technique
See also shown in Figure 1, the position transducer of hot rolling hydraulic jack 1 change or checking process in move mandrel 2 can do reciprocating linear motion along the length direction of position transducer 1 (elongating or shortening) owing to relate to it; And since its to move mandrel 2 thin and have certain elasticity; Position transducer 1 body heavier again (being the irony alloy material) is conducted oneself with dignity easily and is glided, therefore; If in the process of dismounting, replacing or mounting point sensor 1; Once carelessness can cause the bending or the damage of moving mandrel 2 easily, thereby cause the damage of whole position transducer 1, cause the increase of cost.
The model utility content
To the above-mentioned shortcoming that exists in the existing technology, the purpose of the utility model provides a kind of mandrel positioning protection device of oil cylinder position sensor, can avoid moving the mandrel generation bending or the damage of sensor.
For realizing above-mentioned purpose, the utility model adopts following technological scheme:
The mandrel positioning protection device of this oil cylinder position sensor is fixedly arranged on sensor one end and is placed on the mobile mandrel of this end, comprises base and supporting frame; Base is provided with bolt hole and mandrel grooving; Be connected to a fixed through bolt passing through bolt hole and sensor one end end cap, and be sheathed on the mandrel through the mandrel grooving, supporting frame is located on the base; Supporting frame upper end be provided with end cap on the suitable groove of shape of bolt, and cooperate with bolt offset fixing.
Described base is disc, and described mandrel grooving is U-groove bevel and radially offers on the base.
It is tabular that described supporting frame is circular arc, and the bottom is fixedly arranged on the base upper end and is positioned at mandrel grooving one side.
Described groove is a rectangle groove.
In technique scheme; The mandrel positioning protection device of the oil cylinder position sensor of the utility model comprises base and supporting frame, and base is provided with bolt hole and mandrel grooving, is connected to a fixed through bolt passing through bolt hole and sensor one end end cap; And be sheathed on the mandrel through the mandrel grooving; Supporting frame is located on the base, supporting frame upper end be provided with end cap on the suitable groove of shape of bolt, and cooperate with bolt offset fixing.In the replacing sensor process, can play a protective role to mandrel through the mandrel grooving, and can avoid sensor to glide, and cause problems such as bending that mandrel takes place or damage because of deadweight through supporting frame.
Description of drawings
Fig. 1 is the structural drawing of the oil cylinder position sensor of existing technology;
Fig. 2 is the stereogram of the positioning protection device of the utility model;
Fig. 3 is the user mode structural drawing of the positioning protection device of the utility model.
Embodiment
Further specify the technological scheme of the utility model below in conjunction with accompanying drawing and embodiment.
See also Fig. 2～shown in Figure 3; The mandrel positioning protection device 10 of the oil cylinder position sensor of the utility model is fixedly arranged on sensor 1 one ends and is placed on the mobile mandrel 2 of this end; Comprise base 11 and supporting frame 12; Base 11 is provided with pair of bolts hole 13 and a mandrel grooving 14, and base 11 passes bolt hole 13 through bolt 15 and is connected to a fixed with sensor 1 one end end caps 3, and is sheathed on the mandrel 2 through mandrel grooving 14; Can the mandrel 2 that be placed in it be played a protective role through mandrel grooving 14; And supporting frame 12 is located on the base 11, supporting frame 12 upper ends be provided with end cap 3 on several suitable grooves 16 of shape of bolt of cover 4, and cooperate with bolt of cover 4 offset fixing.Described base 11 is disc, and described mandrel grooving 14 is also radially offered on the base 11 for U-groove bevel.It is tabular that described supporting frame 12 is circular arc, and the bottom is fixedly arranged on base 11 upper ends and is positioned at mandrel grooving 14 1 sides.Described groove 16 is a rectangle groove.
Adopt the positioning protection device 10 of the utility model; Simple in structure, easy to use and reliable; In the replacing or checking process of sensor 1; Can play positioning action to the mobile mandrel 2 of sensor 1, prevent to move mandrel 2, play the better protect effect because of deadweight downslide, change in location produce the unnecessary potential risk that is damaged.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model the above embodiment's variation, modification.
