Abstract
The utility model discloses a rotary angle device including a probe and a display connected with each other electrically. It is characterized in that a flange is connected to the probe. A side part of the flange is provided with an annular sleeve. The annular sleeve is provided with a bolt hole axially. A bolt is arranged in the bolt hole. By using the rotary angle device, the probe can be installed on a terminal head of a rotor of a motor conveniently. The equal circumferential division of an embedded wire groove of the motor can be realized further by using the rotary angle device. The rotary angle device in the utility model overcomes shortcomings of the prior art.
Description
Technical field
The utility model belongs to the survey instrument technical field, relates in particular to a kind of anglec of rotation device.
Background technology
The line embedding groove that the rotor of one type of motor is arranged is directly on rotor body, to mill out with groover.And mill line embedding groove, must carry out the circumference five equilibrium to rotor body according to the groove number of preprocessing.And rotor line embedding groove circumference five equilibrium will to reach than higher precision be the difficult problem of this area always.In the prior art, normally realize rotor is carried out line embedding groove circumference five equilibrium at present by equi-index plate.Carry out branch such as rotor line embedding groove circumference needs in advance on equi-index plate, to process halving hole according to the number of line embedding groove by equi-index plate; And certainly exist the machining angle deviation between halving hole and the halving hole; And the size separately of all halving holes is also different, can cause the error that cooperates with latch.So, be branch groove millings such as benchmark with the equi-index plate, the precision of frock self, equi-index plate and latch quality of fit have determined the halving precision of last line embedding groove, this just causes last rotor line embedding groove halving precision is not very high, has finally influenced motor properties.And, utilize equi-index plate to carry out the defective that rotor line embedding groove circumference five equilibrium also exists frock complicacy, complex operation.
For this reason, the inventor expects utilizing anglec of rotation device to carry out rotor line embedding groove circumference five equilibrium, but owing to do not allow punching on the rotor, so just causes the gauge head of existing anglec of rotation device can't be installed on the rotor termination.
The utility model content
The utility model technical matters to be solved provides a kind of anglec of rotation device; This anglec of rotation device can conveniently be installed in gauge head on the rotor termination; And then can realize carrying out the circumference five equilibrium of rotor line embedding groove with anglec of rotation device, overcome the defective that prior art exists.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of anglec of rotation device comprises it is characterized in that the gauge head and the display of mutual electrical connection: also connect a flange on the said gauge head, said flange sidepiece has the annular cover, and said ring-like putting radially has bolt hole, is provided with bolt in the said bolt hole.
In this practicality embodiment, said flange is made up of ring flange and flange shaft, and said annular cover is positioned at a side of ring flange, and said flange shaft is connected the opposite side of ring flange.
Said gauge head is connected with the flange shaft of flange through shaft coupling.Said shaft coupling is a spring coupling.
Adopt technique scheme; The anglec of rotation utensil of the utility model has need on the rotor termination, not punch just can realize gauge head is installed in the advantage of the termination of rotor, and then has realized utilizing anglec of rotation device to carry out the circumference five equilibrium of rotor line embedding groove.
Description of drawings
Be elaborated below in conjunction with accompanying drawing and embodiment the utility model:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the use-pattern synoptic diagram of the utility model;
Among the figure:
The 20-flange, 21-ring flange, 22-flange shaft, 23-annular cover, 24-bolt hole, 25-bolt, 30-spring coupling, 40-anglec of rotation device, 41-gauge head, 42-display, 100-rotor, 101-termination.
Embodiment
As shown in Figure 1, the anglec of rotation device 40 of the utility model, anglec of rotation device 40 is made up of with display 42 interconnective gauge head 41, in addition, also includes flange 20 and spring coupling 30.
Wherein, flange 20 is connected and composed by ring flange 21 and flange shaft 22.The outside of ring flange 21 has ring-like cover 23, ring-like cover 23 radially offer bolt hole 24, be provided with bolt 25 in the bolt hole 24.
The gauge head of anglec of rotation device 40 is connected on the flange shaft 22 of flange 20 through spring coupling 30.
More than be exactly the utility model anglec of rotation device, as shown in Figure 2 during use, ring-like cover 23 on the ring flange 21 is enclosed within on the termination 11 of rotor 100, and tights a bolt 25.Like this, the gauge head 41 of anglec of rotation device 40 just has been installed on the termination 11 of rotor 100.Between two bearing seats 11.
Therefore; Can find out through above-mentioned detailed description; The anglec of rotation utensil of the utility model has need on the rotor termination, not punch just can realize gauge head is installed in the advantage of the termination of rotor, and then has realized utilizing anglec of rotation device to carry out the circumference five equilibrium of rotor line embedding groove.
But; 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 variation, the modification of the above embodiment.
