Fig. 2 is the pin shaft fork schematic internal view of the utility model three.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to explanation Book word can be implemented according to this.
In description of the present utility model, term " transverse direction ", " longitudinal direction ", " on ", " under ", "front", "rear", "left", "right", The orientation or position relationship of the instruction such as " vertical ", " level ", " top ", " bottom ", " interior ", " outer " be based on orientation shown in the drawings or Position relationship, it is for only for ease of description the utility model and simplifies description, is not instruction or implies signified device or member Part must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.
As shown in Fig. 1~2, the utility model provides a kind of three pin shaft forks 1 measurement alley depth measurer, including：
Sleeve 41, it has hollow cavity along its length, and one end of the sleeve 41 is in open-like shape, and the other end is in closing Shape, hollow cavity are available for the first measuring staff 54 to penetrate movement.
Dial gauge 3, its gauge rod coaxially penetrates the blind end of the sleeve 41, and the gauge head of the dial gauge 3 is positioned at described The hollow cavity of sleeve 41, dial gauge 3 are fixed by the blind end of bolt and sleeve 41.
First measuring staff 54, one part are coaxially stretched into by the opening end of sleeve 41 in the hollow cavity of the sleeve 41, the The external part of one measuring staff 54 is fixed with three pin balls 2 by screw 22 and blanking cover 21；
Gauge head connecting rod, it is coaxially fixed on the inserting end of first measuring staff 54, the other end of the gauge head connecting rod Center cave inward the groove to be formed and matched with the gauge head shape of dial gauge 3；
Base 42, its one end are connected with the opening end of institute sleeve 41, and the bottom surface of the other end is more than three pins for circular and diameter The ultimate range of the opening end of yoke 1, the base 42 have the cavity passed through for the first measuring staff 54.
Wherein, the inside of three pin shaft fork 1 is inner chamber reference plane 102 and alley face 101.
In the above-mentioned technical solutions, the cavity opening of three pin shaft forks 1 is set upward, by three pin ball 2 and three in depth measurer The bottom surface of the cavity of pin shaft fork 1 is fixed, and promotes sleeve 41 to the bottom surface of base 42 and the upper end of three pin shaft forks 1 to offset, and now hundred Dividing the gauge head of table 3, dial gauge 3 shows a reading, by the reading and three pin shaft fork marks by the reaction force of gauge head connecting rod The reading of quasi- part is compared, so as to calculate the alley depth of three pin shaft forks 1 in test.
Further, in three described pin shaft forks 1 measurement alley depth measurer, the corresponding base in the middle part of the first measuring staff 54 Formed with stopper slot at 42；Gag lever post 7 (such as bolt), its one end stretch into the stopper slot, the stopper slot through base 42 Length be more than the gag lever post diameter.It is for the measuring staff of activity fixes sleeve 41 and first to set gag lever post and stopper slot 54, both is formed an entirety, and the length of stopper slot enables the relative sleeve 41 of the first measuring staff 54 to be moved along axis.
Further, in three described pin shaft forks 1 measurement alley depth measurer, in addition to position-limiting drum 43, its one end and institute The other end for stating base 42 is coaxially connected；The external part of first measuring staff 54 passes the position-limiting drum 43.Due to the first measuring staff 54 external part is located at outside sleeve 41, in order to which further accurate first measuring staff 54 that limits can only move along its axis, therefore sets Position-limiting drum 43.
Further, in three described pin shaft forks 1 measurement alley depth measurer, the hollow cavity of the sleeve 41 is cylinder Shape；First measuring staff 54 is cylinder；
The cavity of the base 42 is the different cylinder composition of two kinds of diameters, close to the cavity diameter of base 42 of sleeve 41 The diameter of hollow cavity larger and equal to the sleeve 41, the cavity diameter of base 42 away from sleeve 41 are slightly larger than described first The diameter of measuring staff 54, it is to preferably fix the second spacer 62 so to set, and make the second spacer 62 and base 42 avoids phase Support, prevent the second spacer 62 from sliding.
The cavity of the position-limiting drum 43 is equal with the diameter of the hollow cavity of sleeve 41 for cylindrical and diameter；
Also include：
First spacer 61, it is coaxially disposed in the position-limiting drum 43, and with the fixation of the inwall of position-limiting drum 43；
Second spacer 62, it is coaxially disposed the junction in base 42 and sleeve 41, and inwall, sleeve 41 with base 42 Inwall fix；
Wherein, first spacer 61 is equal with the internal diameter of the second spacer 62, and matches somebody with somebody with the gap of the first measuring staff 54 Close, reach being slidably matched for gap very little, it is to prevent the first measuring staff 54 and base 42 to set the first spacer 61 and the second spacer 62 Worn with the inner chamber of sleeve 41.
Further, in three described pin shaft forks 1 measurement alley depth measurer,
The gauge head connecting rod is made up of the Part I 51 of cylinder and the Part II 52 of cylinder, described first 51 are divided coaxially to be fixed with first measuring staff 54, the Part II 52 is coaxially fixed with the Part I 51, and described second The diameter of part 52 is less than the diameter of the Part I 51；
Spring 53, it is sheathed on the Part II 52, and the internal diameter of spring is less than the diameter of the Part I 51, institute The both ends for stating spring offset with the Part I 51 and sleeve 41 respectively.
In the above-mentioned technical solutions, the Part I 51 of gauge head connecting rod props up spring, and its is another in relaxed state for spring One end and the blind end inner faces contact of sleeve 41, when external part movement of the sleeve 41 towards the first measuring staff 54, spring is by crowded Pressure, when the external force on sleeve 41 disappears, the reaction force of spring separates base 42 and the opening end of three pin shaft forks 1, real Existing alley depth measurer automatically resets.
Although embodiment of the present utility model is disclosed as above, it is not restricted in specification and embodiment Listed utilization, it can be applied to various suitable fields of the present utility model completely, for those skilled in the art, Other modification is easily achieved, therefore under the universal limited without departing substantially from claim and equivalency range, this reality Specific details is not limited to new and shown here as the legend with description.
