Description

Motor gear dismounting device

Technical Field

The utility model relates to a dismantle the frock, especially relate to a motor gear dismounting device.

Background

At present, the motor gear dismantling tool is generally used for dismantling a gear in a mode of directly installing the gear on a shaft, and the dismantling purpose can be achieved by using a conventional common tool, however, for example, a hollow shaft is adopted in a Ronz (Lenze) MDEMXX series motor, the gear is installed in the shaft in an interference fit mode, and the conventional tool cannot dismantle the gear.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a motor gear dismounting device can realize pulling down the gear by one end in the quill shaft, and the device simple structure dismantles the success rate height, reduces the workman and dismantles the burden.

Motor gear dismounting device include: the middle part of the base is provided with a through hole; the gantry support is arranged above the through hole and is fixedly connected with the base; the nut is fixedly connected with the gantry support and is coaxially arranged with the through hole; and a lead screw adapted to the nut; the lead screw vertically penetrates through the gantry support, a top rod is fixed at one end of the lead screw, a rotating handle is fixed at the other end of the lead screw, and a gear clamping jaw mechanism which is rotationally connected with the lead screw is arranged above the top rod.

Preferably, the gear jaw mechanism comprises a threaded sleeve adapted to the lead screw; and the clamping jaws are fixed on the outer wall of the threaded sleeve.

The threaded sleeve is sleeved with the screw rod, the clamping jaws are at least two groups arranged around the circumferential direction of the outer wall of the threaded sleeve, the clamping jaws and the ejector rods form a fixed space for accommodating the gear, the positions of the clamping jaws on the screw rod can be adjusted by rotating the threaded sleeve, and the clamping jaws can conveniently hook the gear.

Preferably, the jaw comprises a first connecting arm, one end of which is hinged with the threaded sleeve; one end of the second connecting arm is hinged with the other end of the first connecting arm; and one end of the third connecting arm is hinged with the other end of the second connecting arm, and the other end of the third connecting arm is provided with a hook bent towards the side of the threaded sleeve.

When the device works, the gear at the end part of the motor penetrates through the through hole in the base, the base is abutted against the end cover of the motor, the positions of the first connecting arm, the second connecting arm and the third connecting arm are adjusted, the hook hooks the bottom of the gear, the lead screw is kept still, and the threaded sleeve is rotated to enable the clamping jaw and the ejector rod to form a fixing space for accommodating the gear; then the rotating handle is rotated to enable the screw rod to move upwards, and the base abuts against the end cover of the motor, so that the clamping jaws and the gear are driven to move upwards by rotating the rotating handle, and the gear is pulled out of the motor.

The utility model has the advantages that:

realized dismantling the gear by the interior one end of quill shaft, the device simple structure dismantles the success rate height, reduces workman and dismantles the burden.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and 2, the motor gear detaching device of the present invention comprises: a base 1, wherein the middle part of the base is provided with a through hole 2; the gantry support 3 is arranged above the through hole 2 and is fixedly connected with the base 1; the nut 4 is fixedly connected with the gantry support 3 and is coaxially arranged with the through hole 2; and a lead screw 5 adapted to the nut 4; the lead screw 5 vertically penetrates through the gantry support 3, a top rod 6 is fixed at one end of the lead screw, a rotating handle 7 is fixed at the other end of the lead screw, and a gear claw mechanism which is rotationally connected with the lead screw 5 is arranged above the top rod 6. The gear claw mechanism comprises a threaded sleeve 8 matched with the lead screw 5; and a jaw fixed on the outer wall of the threaded sleeve 8. The jaw comprises a first connecting arm 9, one end of which is hinged with the threaded sleeve 8; a second connecting arm 10, one end of which is hinged with the other end of the first connecting arm 9; and one end of the third connecting arm 11 is hinged with the other end of the second connecting arm 10, and the other end of the third connecting arm is provided with a hook 12 which is bent towards the threaded sleeve 8.

The threaded sleeve 8 is sleeved with the screw rod 5, the position of the jaw on the screw rod 5 can be adjusted by rotating the threaded sleeve 8, the jaw can conveniently hook the gear 13, and the jaw and the ejector rod 6 form a fixed space for accommodating the gear 13. When the automatic clamping device works, the gear 13 at the end part of the motor 14 penetrates through the through hole 2 on the base, the base 1 is abutted against the end cover of the motor, the positions of the first connecting arm 9, the second connecting arm 10 and the third connecting arm 11 are adjusted, the hook 12 hooks the bottom of the gear 13, the screw rod 5 is kept still, and the threaded sleeve 8 is rotated to enable the clamping jaws and the ejector rod 6 to fix the gear 13; then the rotating handle 7 is rotated to make the screw rod 5 move upwards, and the base 7 is abutted on the end cover of the motor, so that the rotating handle 7 drives the clamping jaws and the gear 13 to move upwards, and the gear 13 is pulled out of the motor 14.

Of course, the above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the embodiments of the present invention. The present invention is not limited to the above examples, and the technical field of the present invention is equivalent to the changes and improvements made in the actual range of the present invention, which should be attributed to the patent coverage of the present invention.
