Technical Field

[0001] This utility model relates to the field of motor housing processing, specifically a housing processing device for DC motor processing. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. The working principle of a DC generator is to convert the alternating electromotive force induced in the armature coil into a direct current electromotive force when it is drawn out from the brush end by the commutation action of the commutator and the brushes.

[0003] In the prior art, after the DC motor is manufactured, the center hole of the motor housing needs to be polished and refined to improve the dimensional accuracy. The existing housing polishing operation requires conveying and positioning the cylindrical motor housing, and then drilling and slotting the motor housing with a slotting drill bit. Since motor housings have different specifications, multiple positioning blocks need to be adjusted one by one when positioning motor housings of different specifications. Based on this, in order to facilitate the clamping and positioning of motor housings of different specifications, this utility model proposes a housing processing device for DC motor processing.

[0016] Please see Figures 1-4 In this embodiment of the utility model, a housing processing device for DC motor processing includes a worktable 1, a movable seat 2 connected to the worktable 1 via a vertical slide, a base 3 provided on one side of the worktable 1, a movable plate 4 slidably mounted on the top of the base 3, a first cylinder 5 mounted on the top of the movable plate 4, a second cylinder 7 connected to the movable plate 4 installed inside the worktable 1, and a positioning mechanism 6 provided on the worktable 1 and the movable plate 4. Positioning mechanism 6 includes a positioning unit and a transmission unit; The positioning unit is used to position and transport the motor housing on the upper surface of the worktable 1; The transmission unit is used to provide power for the movement of the positioning unit; The positioning unit includes a first positioning rod 601, a first clamping ring 602, a second positioning rod 603, and a second clamping ring 604; The first positioning rod 601 fixes the output end of the first cylinder 5, and the first positioning rod 601 is used to synchronously drive the first clamping ring 602 to move. The first clamping ring 602 is fixed to the outer wall of the first positioning rod 601. The first clamping ring 602 is used to position and clamp one side of the outer wall of the motor housing. The second positioning rod 603 is fixed to the end of the transmission rod 605. The second positioning rod 603 is used to synchronously drive the second clamping ring 604 to move. The second clamping ring 604 is fixed to the outer wall of the second positioning rod 603. The second clamping ring 604 is used to position and clamp the other outer wall of the motor housing. The transmission unit includes a transmission rod 605, a first rack 606, a gear 607, a second rack 608, and a transmission plate 609; The transmission plate 609 is axially slidably installed inside the worktable 1, and the transmission plate 609 is used to synchronously drive the transmission rod 605 to move axially. The first rack 606 is laterally slidably mounted on the top of the transmission plate 609. The first rack 606 is used to synchronously drive the transmission rod 605 to move laterally. The transmission rod 605 is fixed to the top of the first rack 606, and the transmission rod 605 is used to synchronously drive the second clamping ring 604 to move laterally; Gear 607 is rotatably mounted on the top of transmission plate 609, and gear 607 is used to give rotational thrust to first rack 606; The second rack 608 is fixed to the outer wall of the first positioning rod 601 by a connecting rod and is slidably connected to the top of the transmission plate 609. The second rack 608 is used to give the gear 607 rotational thrust.

[0017] In this embodiment: With this structure, when positioning and conveying the motor housing is required, the second cylinder 7 connected to the movable plate 4 is activated. The second cylinder 7 drives the movable plate 4 to move laterally. The laterally moving movable plate 4 synchronously drives the first cylinder 5, the first positioning rod 601, and the first clamping ring 602 mounted at the top to move laterally as well. Simultaneously, the second rack 608 fixed to the outer wall of the movable plate 4 also moves laterally. The laterally moving second rack 608 provides rotational thrust to the gear 607, causing the gear 607 to rotate under the force. 7 will provide a lateral moving thrust to the first rack 606. Due to the action of the first rack 606, the first rack 606 and the second rack 608 will move closer to each other, so that the transmission rod 605 connected to the first rack 606 will synchronously drive the second positioning rod 603 and the second clamping ring 604 to move closer to the first positioning rod 601 and the first clamping ring 602, thereby clamping and positioning the motor housing on the upper surface of the worktable 1. The motor housing located directly below the movable seat 2 will be polished and finished by the movable seat 2 installed on the worktable 1. After processing is completed, by activating the first cylinder 5, the operation of the first cylinder 5 will push the first positioning rod 601 and the first clamping ring 602 to move axially. The motor housing inside the first clamping ring 602 and the second clamping ring 604 will also move axially synchronously. Then the second positioning rod 603 and the second clamping ring 604 will also move axially synchronously, thereby driving the transmission rod 605, the first rack 606, and the transmission plate 609 to move axially along the inner side of the worktable 1 synchronously. The outer wall of the first positioning rod 601 is connected to the second rack 606 by the connecting rod. The rack 608 will also move along with the first positioning rod 601, so that the first rack 606, gear 607, and gear 607 will always remain in a meshed state. Then, when the second cylinder 7 is used again to push the first positioning rod 601 and the first clamping ring 602 away from the second positioning rod 603 and the second clamping ring 604, the first positioning rod 601 and the second positioning rod 603 will move away from each other under the action of the gear 607 until the first cylinder 5 pushes the first positioning rod 601 and the second positioning rod 603 to reset, and so on.

[0018] Please refer to this carefully. Figures 1-4The workbench 1 has a groove formed inside for the axial movement of the transmission plate 609 and the first rack 606. The top of the transmission plate 609 has a groove formed for the axial movement of the first rack 606. The outer walls of the first rack 606 and the second rack 608 mesh with the outer wall of the gear 607. The second rack 608 and the first rack 606 are obliquely symmetrically distributed on the outer wall of the gear 607. There are multiple second clamping rings 604 and first clamping rings 602. The multiple second clamping rings 604 and first clamping rings 602 are evenly distributed on the outer walls of the second positioning rod 603 and the first positioning rod 601. The first clamping rings 602 and the second clamping rings 604 are in pairs, and the first clamping rings 602 and the second clamping rings 604 in a pair are symmetrically distributed vertically.

[0019] In this embodiment: With this structure, when positioning and clamping motor housings of different specifications, the ends of the second clamping ring 604 and the first clamping ring 602, which are symmetrically distributed vertically, can overlap, so that the motor housing is always kept directly below the movable seat 2, which facilitates the grinding and processing of the motor housing.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
