Description

End cover transition plate machining tool

Technical Field

The utility model relates to an end cover cab apron processing frock belongs to the machine-building technical field.

Background

The motor is a power source for lifting the elevator and is a core part in the elevator, the motor of the end cover transition plate supports the rotor of the motor at two ends of the motor and is disc-shaped, the middle part of the motor is provided with a bearing shaft matching opening, and the motor needs to be matched with a motor shell and a bearing shaft, so that high precision and flatness are needed.

Disclosure of Invention

The utility model aims to solve the technical problem that an end cover crosses cab apron processing frock is provided, can even atress when making the end cover cross the cab apron fixed, reduces the condition that its damage warp, can solve prior art's not enough.

The technical scheme of the utility model is that: the end cover transition plate machining tool comprises a three-jaw chuck, three clamping jaws of the three-jaw chuck are respectively provided with a third disc part, a third circular ring part is arranged on the third disc part, the three third disc parts respectively move towards the center along with the corresponding clamping jaws to approach or withdraw, and when the three third disc parts are combined to form a disc, the three third circular ring parts form a circular ring which is hooped and fixed on the outer edge of the end cover transition plate. The end cover transition plate is fixedly hooped on the outer edge of the end cover through the circular ring, so that the fixed stress area of the end cover transition plate is increased, the end cover transition plate is uniformly stressed, and deformation or local damage is not easy to occur.

And the third disc parts are fixedly connected to corresponding clamping jaws, each clamping jaw is fixedly connected with a supporting rod, and the supporting rods on the corresponding clamping jaws are fixedly connected with the corresponding third disc parts. One third disc spare and jack catch fixed connection back rethread bracing piece fixed connection increase joint strength.

Further every the jack catch is fixed to be welded in corresponding one-third disc spare middle part, every jack catch fixed connection's bracing piece is two, connects respectively in the jack catch both sides. The jack catch is fixed to be welded in one-third disc spare middle part, and both sides reuse bracing piece welded fastening supports the connection more firmly stable.

The one-third circular ring piece and the corresponding one-third circular disc piece are of an integral structure. Convenient processing, the whole has better firm intensity.

Furthermore, a waist-shaped groove is radially formed in the one-third disc part, a screw hole corresponding to the waist-shaped groove is formed in the one-third disc part, and the one-third disc part is fixedly installed on the corresponding one-third disc part through a bolt. Can change the one-third ring spare of equidimension not according to the size of end cover transition plate and tighten it fixedly, the adaptability is better.

To sum up, the utility model provides a convenient cab apron atress is even fixed with unidimensional end cover not, and cab apron processing frock is crossed to the end cover that makes its non-deformable and stable in structure.

Drawings

Fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic structural diagram according to a first embodiment;

fig. 3 is a schematic structural diagram of the second embodiment.

Shown in the figure: a chuck 1; a claw 2; one third disc member 3; one third of a circular ring member 4; an end cover transition plate 5; a support rod 6; a waist-shaped groove 7; and a bolt 8.

Detailed Description

The embodiment of the utility model discloses an: as shown in fig. 1 to 2, an end cover transition plate processing tool comprises a three-jaw chuck, the three-jaw chuck comprises a chuck 1 and three clamping jaws 2 mounted on the chuck 1, three clamping jaws 2 of the three-jaw chuck are respectively provided with a third disc part 3, the third disc part 3 is provided with a third circular ring part 4, the three third disc parts 3 respectively move towards the center along with the corresponding clamping jaws 2 to approach or withdraw, and when the three third disc parts 3 are combined to form a disc, the three third circular ring parts 4 form a circular ring which is tightly hooped and fixed on the outer edge of an end cover transition plate 5. The end cover transition plate 5 is fixedly hooped on the outer edge of the end cover transition plate through a circular ring, so that the fixed stress area of the end cover transition plate 5 is increased, the end cover transition plate is uniformly stressed, and deformation or local damage is not easy to occur.

The preferential three third disc spare 3 fixed connection of this embodiment is on corresponding jack catch 2, equal fixedly connected with bracing piece 6 on every jack catch 2, bracing piece 6 and corresponding third disc spare 3 fixed connection on the jack catch 2 that corresponds. One third disc spare 3 and jack catch 2 fixed connection back rethread bracing piece 6 fixed connection increase joint strength.

Each jaw 2 preferred in this embodiment is fixedly welded in the middle of the corresponding one-third disc member 3, and two support rods 6 are fixedly connected to each jaw 2 and are respectively connected to two sides of each jaw 2. The jack catch 2 is fixed to be welded in one-third disc spare 3 middle part, and the 6 welded fastening of left and right sides reuse bracing piece support, support to connect more firmly stably.

The preferred one-third ring member 4 of this embodiment is of unitary construction with the corresponding one-third disc member 3. Convenient processing, the whole has better firm intensity.

Example two: as shown in fig. 3, a waist-shaped groove 7 is radially formed in the one-third disc member 3, a screw hole corresponding to the waist-shaped groove 7 is formed in the one-third disc member 4, the one-third disc member 3 is fixedly mounted on the corresponding one-third disc member 3 through a bolt 8, and compared with the one-third disc member 3 and the one-third disc member 4 which are integrally structured, the one-third disc member 4 and the one-third disc member 3 of the present embodiment are of a detachable structure, and the one-third disc member 4 with different sizes can be replaced according to the size of the end cover transition plate 5 to be tightly hooped and fixed, so that the adaptability is better.
