Summary of the Invention

[0006] The purpose of this invention is to provide a positioning and clamping device for machining motor housings, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a positioning and clamping device for processing motor housing, comprising a base plate, a support block fixedly connected to the bottom of the base plate, a support column fixedly connected to the top of the base plate, a clamping mechanism fixedly connected inside the base plate, a lifting mechanism fixedly connected to the two support columns at the front and rear sides, a rotating mechanism provided on the lifting mechanism, and the rotating mechanism being located on the top of the base plate;

[0008] The clamping mechanism includes a moving component and a limiting component, wherein the limiting component is disposed on the moving component;

[0009] The moving component includes a second T-slot, which is formed on the top of the base plate. A rectangular slot is formed on the top of the base plate. A second T-block is slidably connected inside the second T-slot. A clamping ring is fixedly connected to the top of the second T-block. A fixing plate is fixedly connected to the side of the second T-block near the rectangular slot. Sliding grooves are formed on both the left and right sides of the inner wall of the rectangular slot.

A fixing block is rotatably connected to the rotating rod surface. The fixing blocks are all located on both sides of the second gear. The top of the fixing block is fixedly connected to the bottom of the fixing plate.

[0010] According to the above technical solution, there are four second T-shaped grooves and four rectangular grooves, and the four second T-shaped grooves and four rectangular grooves are arranged in a circular array at the center of the top of the base plate.

[0011] According to the above technical solution, the limiting component includes slots, which are densely arranged on the top of the base plate. A telescopic insert is fixedly connected to the bottom of the fixing plate. Hinges are fixedly connected to both sides of the fixing plate. A locking block is hinged to the top of the hinge block. A locking block is fixedly connected to the bottom of the locking block. A slot is provided on the top of the fixing plate. The top of the slot is set as an opening. The inside of the slot and the surface of the locking block are engaged.

[0012] According to the above technical solution, the slot is set on one side of the rectangular groove, the top of the slot is set as an opening, the surface of the telescopic insert plate is inserted into the inside of the slot, and when the telescopic insert plate is stretched and inserted into the slot, it can limit and fix the position of the fixing plate.

[0013] According to the above technical solution, the lifting mechanism includes a connecting seat, which is fixedly connected to the adjacent side of two front and rear support columns. A first motor is fixedly connected to the top of the connecting seat, and a threaded rod is fixedly connected to the bottom of the first motor. The surface of the threaded rod is rotatably connected to the inside of the base plate, and a connecting block is threadedly connected to the surface of the threaded rod. A first T-slot is opened inside the adjacent side of the two left and right support columns, and a first T-block is slidably connected inside the first T-slot. A connecting plate is fixedly connected to the adjacent side of the two left and right first T-blocks, and a long plate is fixedly connected between the two connecting plates. The connecting plates and the connecting blocks are fixedly connected.

[0014] According to the above technical solution, there are four threaded rods, and the thread specifications on the surfaces of the four threaded rods are the same and the direction is the same. When the four threaded rods rotate, the connecting block can move to the same side.

[0015] According to the above technical solution, there are four connecting plates, which are arranged in pairs. The two connecting plates on the left and right sides that are far apart from each other are fixedly connected to the connecting block.

[0016] According to the above technical solution, the rotating mechanism includes a ring, which is fixedly connected between two long plates. An annular toothed rack is fixedly connected to the top of the long plates. An annular groove is formed on the inner wall of the ring.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0018] In this invention, by setting a moving component, when the second gear meshes with the tooth rack surface while the moving component is in operation, the second T-shaped block slides in the second T-shaped groove, and at the same time the slider slides in the groove. At this time, the four clamping rings can open outwards until the clamping rings are completely attached to the inner wall of the motor housing, so that the motor housing can be fixed in position at the top of the base plate.

[0019] This invention, by setting a limiting component, allows the telescopic insert plate to be stretched and inserted into the slot when the limiting component is in operation, and the locking block to be locked into the slot, thereby limiting and fixing the position of the clamping ring, preventing the clamping ring from moving, and preventing the motor housing from moving.

[0020] This invention, by setting up a lifting mechanism, allows four connecting blocks to move to the same side on the surface of the four threaded rods when the lifting mechanism is in operation. When the connecting blocks move, they can drive the connecting plate, which in turn drives the first T-block, which drives the long plate, which in turn drives the ring to move up and down. This allows the spray head to spray at different heights of the motor housing when it is spraying the surface of the motor housing.

[0021] This invention, by setting a rotating mechanism, allows the first gear and the annular gear rack to mesh and rotate around the annular gear rack when the rotating mechanism is in operation. This enables the surface of the motor housing to be sprayed evenly. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] This invention provides the following technical solutions:

[0034] Example 1

[0035] Combination Figures 1 to 5 A positioning and clamping device for processing motor housing includes a base plate 2, a support block 1 fixedly connected to the bottom of the base plate 2, a support column 5 fixedly connected to the top of the base plate 2, a clamping mechanism 6 fixedly connected inside the base plate 2, and a lifting mechanism 3 fixedly connected to one side of the front and rear support columns 5 that are close to each other. A rotating mechanism 4 is provided on the lifting mechanism 3 and the rotating mechanism 4 is located on the top of the base plate 2.

[0036] The clamping mechanism 6 includes a moving component 61 and a limiting component 62. The limiting component 62 is disposed on the moving component 61. The moving component 61 includes a second T-slot 612, which is formed on the top of the base plate 2. A rectangular groove 616 is formed on the top of the base plate 2. A second T-block 611 is slidably connected inside the second T-slot 612. A clamping ring 6102 is fixedly connected to the top of the second T-block 611. A fixing plate 6103 is fixedly connected to the side of the second T-block 611 near the rectangular groove 616. The inner wall of the rectangular groove 616 has sliding grooves 614 on both the left and right sides. A slider 613 is slidably connected inside the sliding groove 614. A third motor 617 is fixedly connected to one side of the slider 613, and a rotating rod 6101 is fixedly connected to the other side of the third motor 617. The surface of the rotating rod 6101 is rotatably connected to the inside of the slider 613. A second gear 619 is fixedly connected to the center of the surface of the rotating rod 6101. A gear rack 615 is fixedly connected to the bottom of the inner wall of the rectangular groove 616. The top of the gear rack 615 meshes with the surface of the second gear 619. The connecting rod 6101 is rotatably connected to a fixing block 618, which is located on both sides of the second gear 619. The top of the fixing block 618 is fixedly connected to the bottom of the fixing plate 6103. There are four second T-slots 612 and rectangular slots 616, which are arranged in a circular array at the top center of the base plate 2. The limiting component 62 includes slots 621, which are densely arranged on the top of the base plate 2. The bottom of the fixing plate 6103 is fixedly connected to the fixing component 6103. There is a telescopic insert plate 622, and hinge blocks 623 are fixedly connected to both sides of the fixed plate 6103. A locking block 625 is hinged to the top of the hinge block 623, and a locking block 626 is fixedly connected to the bottom of the locking block 625. A slot 624 is opened on the top of the fixed plate 6103. The top of the slot 624 is set as an opening. The inside of the slot 624 and the surface of the locking block 626 are engaged. A slot 621 is set on one side of the rectangular slot 616. The top of the slot 621 is set as an opening. The surface of the telescopic insert plate 622 and the inside of the slot 621 are inserted into it.

[0037] Furthermore, by setting the moving component 61, when the second gear 619 meshes with the surface of the gear rack 615 while the moving component 61 is in operation, the second T-block 611 slides in the second T-groove 612, and at the same time the slider 613 slides in the groove 614. At this time, the four clamping rings 6102 can open outwards until the clamping rings 6102 are completely in contact with the inner wall of the motor housing, so that the motor housing can be fixed in position at the top of the base plate 2. By setting the limiting component 62, when the limiting component 62 is in operation, the telescopic insert 622 is stretched and inserted into the slot 621, and the locking block 626 is locked into the slot 624, so that the position of the clamping ring 6102 can be fixed in position, preventing the clamping ring 6102 from moving and preventing the motor housing from moving. When the telescopic insert 622 is stretched and inserted into the slot 621, the fixed plate 6103 can be fixed in position.

[0038] Example 2

[0039] See Figure 1-6 Based on Embodiment 1, the lifting mechanism 3 further includes a connecting seat 37, which is fixedly connected to the two front and rear support columns 5 on the side closest to each other. A first motor 31 is fixedly connected to the top of the connecting seat 37, and a threaded rod 32 is fixedly connected to the bottom of the first motor 31. The surface of the threaded rod 32 is rotatably connected to the inside of the base plate 2. A connecting block 33 is threadedly connected to the surface of the threaded rod 32. A first T-shaped groove 34 is opened inside the two support columns 5 on the side closest to each other. A first T-shaped block 36 is slidably connected inside the first T-shaped groove 34. A connecting plate 35 is fixedly connected to the side closest to each of the two first T-shaped blocks 36 on the left and right. A long plate 38 is fixedly connected between the two connecting plates 35. The connecting plate 35 and the connecting block 33 are fixedly connected. There are four threaded rods 32, and the thread specifications on the surface of the four threaded rods 32 are the same and the direction is the same. There are four connecting plates 35, which are in pairs. The two connecting plates 35 on the side furthest from each other on the left and right are fixedly connected to the connecting block 33.

[0040] Furthermore, by setting up a lifting mechanism 3, when the four threaded rods 32 rotate under the operation of the lifting mechanism 3, the four connecting blocks 33 can move to the same side on the surface of the four threaded rods 32. When the connecting blocks 33 move, they can drive the connecting plate 35, the connecting plate 35 can drive the first T-shaped block 36, the first T-shaped block 36 can drive the long plate 38, and the long plate 38 can drive the ring 41 to move up and down. At this time, when the spray nozzle 71 sprays the surface of the motor housing, it can spray the motor housing at different heights. When the four threaded rods 32 rotate, the connecting blocks 33 can move to the same side.

[0041] Example 3

[0042] See Figure 1-8Furthermore, based on Embodiment 1, the rotating mechanism 4 further includes a ring 41, which is fixedly connected between two long plates 38. A ring toothed rack 42 is fixedly connected to the top of the long plates 38. An annular groove 43 is provided on the inner wall of the ring 41. An annular slider 44 is slidably connected inside the annular groove 43. A long block 46 is fixedly connected to one side of the annular slider 44. A second motor 47 is fixedly connected to the side of the long block 46 near the annular groove 43. A rotating shaft 45 is fixedly connected to the other side of the second motor 47. A first gear 48 is fixedly connected to the surface of the rotating shaft 45. The surface of the first gear 48 meshes with the top of the annular toothed rack 42. A pipe 7 is fixedly connected inside the long block 46. A nozzle 71 is fixedly connected to the right side of the pipe 7. The nozzle 71 is located on one side of the long block 46.

[0043] Furthermore, by setting a rotating mechanism 4, when the first gear 48 and the annular gear rack 42 are meshed and connected under the operation of the rotating mechanism 4, the first gear 48 can rotate around the annular gear rack 42. At this time, the surface of the motor housing can be sprayed evenly.

[0044] In actual operation, when using this device to clamp the motor housing, the motor housing can be placed on top of the base plate 2, and simultaneously on the outer surface of the clamping ring 6102. Since the size of the motor housing is inconsistent, the third motor 617 can be activated. When the third motor 617 drives the rotating rod 6101 to rotate within the slider 613, the rotating rod 6101 drives the second gear 619 to rotate. Because the second gear 619 meshes with the gear rack 615, the second gear 619 can move on the surface of the gear rack 615. When the second gear 619 moves, the slider 613 is also driven to slide within the groove 614. Simultaneously, the rotating rod 6101 drives the fixing block 618, which in turn drives the fixing plate 6103. 6103 drives the second T-shaped block 611 to slide within the second T-shaped groove 612, allowing all four clamping rings 6102 to open until they are fully fitted against the inner wall of the motor housing, preventing the motor housing from moving. When the fixed plate 6103 is positioned, the telescopic insert plate 622 can be stretched and inserted into the slot 621, and then the locking block 625 can be moved to hinge the locking block 625 and the hinge block 623. At this time, the locking block 625 and the hinge block 623 are folded together, and the locking block 625 can drive the locking block 626 to engage in the slot 624. This can fix the fixed plate 6103 in position and fix the clamping rings 6102 in position, preventing them from moving.

[0045] When it is necessary to spray the surface of the motor housing, the second motor 47 and the first motor 31 can be started simultaneously. When the second motor 47 is started, it drives the rotating shaft 45 to rotate. The rotating shaft 45 can drive the first gear 48 to rotate. When the first gear 48 and the annular gear rack 42 are meshed, the first gear 48 can rotate around the annular slide groove 43. When the first gear 48 rotates, it drives the rotating shaft 45, which drives the second motor 47. The second motor 47 drives the long block 46, which drives the annular slider 44 to slide in the annular slide groove 43. At this time, the spray nozzle 71 can spray the surface of the motor housing around the perimeter.

[0046] When the first motor 31 is started, the first motor 31 can drive the threaded rod 32 to rotate in the base plate 2. When the four threaded rods 32 rotate, the four connecting blocks 33 can move to the same side on the four threaded rods 32. When the connecting blocks 33 move, they can drive the connecting plate 35. The connecting plate 35 can drive the first T-shaped block 36 to slide in the first T-shaped groove 34. On the other hand, the connecting plate 35 can drive the long plate 38. The long plate 38 can drive the ring 41 to move. At this time, when spraying the surface of the motor housing, it is also possible to spray the motor housing at different height positions.
