Description

Technical Field

[0001] This utility model relates to the field of motor end cover processing technology, and in particular to an auxiliary tooling for end cover processing. Background Technology

[0002] The motor end cover is the cover of the motor housing. It is generally divided into a front cover and a rear cover. The motor end cover intermittently connects the stator and rotor through bearings and is one of the most critical components of the motor product. When processing the end cover, auxiliary tooling is required to fix the end cover.

[0003] The prior art (publication number: CN219542341U) discloses a positioning fixture for processing motor end caps, including a base, two support seats slidably connected to the top of the base, an adjustment mechanism for adjusting the movement of the two support seats on the base, a fixing plate fixedly connected to the top of the support seats, a limiting mechanism on the fixing plate, a side plate fixedly connected to the top of the fixing plate, a pressing mechanism on the side plate, and an installation groove on the top of the base, in which a collection frame is provided.

[0004] While the aforementioned patent can prevent the end cap from warping during processing and improve the positioning effect of the device, it has the following drawbacks: during use, the end cap must be processed before the disassembly and installation of the end cap can be performed. This makes it impossible to complete the above operations during processing, which can easily lead to a waste of time and affect work efficiency. Further improvements are needed. Therefore, an auxiliary tooling for end cap processing is proposed. Utility Model Content

[0005] The main purpose of this utility model is to provide an auxiliary tooling for end cap processing, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An auxiliary tooling for processing end caps includes a base plate. A circular plate is movably connected to the upper end of the base plate. Two U-shaped plates, symmetrically distributed front and back, are installed on the upper end of the circular plate. Screws are threaded to the left and right ends of the two U-shaped plates. Two fixing blocks for fixing the end caps are slidably connected to the lower inner walls of the two U-shaped plates. The two fixing blocks are symmetrically distributed left and right. Four screws are movably inserted into the two U-shaped plates and movably connected to the four fixing blocks. A rectangular groove is formed in the middle of the lower inner wall of the two U-shaped plates. A horizontal plate is installed between the front and rear inner walls of the two rectangular grooves. Four positioning posts arranged in a rectangular array are provided in the two rectangular grooves. The circular plate is rotatable, thereby driving the end caps in the two U-shaped plates to alternate positions.

[0008] Preferably, a motor is installed at the lower end of the base plate, a worm is fixedly connected to the output end of the motor, a worm gear is meshed with the worm, a connecting shaft is fixedly sleeved inside the worm gear, and a bearing seat is movably connected to the right end of the worm, and the bearing seat is installed on the base plate.

[0009] Preferably, the upper end of the connecting shaft is movably inserted into the upper end of the base plate and fixedly connected to the lower end of the circular plate.

[0010] Preferably, the lower inner walls of the two rectangular grooves are slidably connected to two symmetrically distributed sliding plates. A positive and negative threaded rod is threaded between two adjacent sliding plates. The ends of the two positive and negative threaded rods that are close to each other are movably connected to the inner walls of the two rectangular grooves, and the ends of the two positive and negative threaded rods that are far from each other are movably inserted into the outer sides of the two U-shaped plates and fixedly connected to a knob.

[0011] Preferably, the lower ends of the four positioning posts located on one side are fixedly connected to the upper ends of the two adjacent slide plates, and there is a gap between the outer surface of the positioning posts and the inner wall of the horizontal plate and the rectangular groove.

[0012] Preferably, two fixing plates symmetrically distributed front and back are installed at both the left and right ends of the base plate.

[0013] Preferably, a baffle is installed at the upper center of the circular plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By setting up a motor, worm gear, worm wheel, connecting shaft, and circular plate to work together, work efficiency can be improved. When the rear end cover is being processed, the end cover to be processed is fixed in the front U-shaped plate. After the rear end cover is processed, the motor is controlled to drive the worm gear to rotate, the worm gear drives the worm wheel to rotate, and the worm wheel drives the circular plate to rotate half a revolution through the connecting shaft, so that the two U-shaped plates alternate positions to process the end cover that has moved to the rear. Then the processed end cover is removed and a new end cover is installed. Other operation steps can be completed during processing, reducing time waste and improving the continuity of operation and productivity.

[0016] 2. By setting up positive and negative threaded rods and sliding plates to work together, the distance between the front and rear positioning pins can be adjusted. When the size of the motor end cover is large, turning the knob will drive the positive and negative threaded rods to rotate. The positive and negative threaded rods will drive the two sliding plates to move away from each other, thereby increasing the distance between the front and rear positioning pins. This makes it easier to position larger end covers and improves the applicability of the device. Attached Figure Description

[0026] like Figures 1-5As shown, an auxiliary tooling for end cap processing includes a base plate 1. A circular plate 3 is movably connected to the upper end of the base plate 1. Two U-shaped plates 4, symmetrically distributed front and back, are installed on the upper end of the circular plate 3. Screws 9 are threaded to the left and right ends of the two U-shaped plates 4. Two fixing blocks 8 for fixing the end cap are slidably connected to the lower inner walls of the two U-shaped plates 4. The two fixing blocks 8 are symmetrically distributed left and right. Four screws 9 are movably inserted into the two U-shaped plates 4 and movably connected to the four fixing blocks 8 respectively. A rectangular groove 5 is formed in the middle of the lower inner wall of each of the two U-shaped plates 4. A horizontal plate 6 is installed between the front and rear inner walls of each of the two rectangular grooves 5. Four positioning posts 7, arranged in a rectangular array, are provided in each of the two rectangular grooves 5. The positioning posts 7 are used to position the end cap, facilitating rapid subsequent machining. To reduce subsequent positioning time, the base plate 1 is installed on the machining center, aligning the rear U-shaped plate 4 with the machining position on the machining center. When the rear motor end cover is being machined, the end cover to be machined is fixed inside the front U-shaped plate 4, and the outer surface of the end cover is held in place by the positioning pin 7, so that the end cover is located in the center of the U-shaped plate 4. Then, the two screws 9 on the front are rotated, causing the two fixing blocks 8 on the front to move closer to the outer surface of the end cover and fix the end cover. After the rear end cover is machined, the circular plate 3 is rotated half a turn, so that the two U-shaped plates 4 alternate positions to machine the end cover that has moved to the rear. Then, the machined end cover is removed and a new end cover is installed. Other operation steps can be completed during the machining process, reducing wasted time and improving the continuity of operation and productivity.

[0027] To automatically rotate the circular plate 3 and fix it in a designated position, a motor 10 is installed at the lower end of the base plate 1. A worm gear 11 is fixedly connected to the output end of the motor 10. The worm gear 11 is meshed with a worm wheel 13. The worm gear 11 and the worm wheel 13 are self-locking. A connecting shaft 14 is fixedly sleeved inside the worm wheel 13. A bearing seat 12 is movably connected to the right end of the worm gear 11. The bearing seat 12 is used to support the rotation of the worm gear 11 and is installed on the base plate 1. The upper end of the connecting shaft 14 is movably inserted into the upper end of the base plate 1 and fixedly connected to the lower end of the circular plate 3. In use, the motor 10 is controlled to drive the worm gear 11 to rotate, the worm gear 11 drives the worm wheel 13 to rotate, and the worm wheel 13 drives the circular plate 3 to rotate half a revolution through the connecting shaft 14.

[0028] In addition, when the end cap is large, in order to position the larger end cap, two symmetrically distributed sliding plates 15 are slidably connected to the lower inner walls of the two rectangular grooves 5. A common threaded rod 16 is threaded between adjacent sliding plates 15. The ends of the two threaded rods 16 that are close to each other are movably connected to the inner walls of the two rectangular grooves 5, while the ends that are far apart are movably inserted into the outer sides of the two U-shaped plates 4 and fixedly connected to knobs 17. The lower ends of the four positioning pins 7 located on one side are fixedly connected to the upper ends of the two adjacent sliding plates 15. Two symmetrically distributed positioning posts 7 are installed on each slide plate 15. There is a gap between the outer surface of the positioning posts 7 and the inner wall of the horizontal plate 6 and the rectangular groove 5. When the size of the motor end cover is large, rotating the knob 17 drives the positive and negative threaded rods 16 to rotate. The positive and negative threaded rods 16 drive the two slide plates 15 to move away from each other, so that the distance between the front and rear positioning posts 7 increases, which is convenient for positioning the larger end cover. When the size of the motor end cover is small, rotating the knob 17 in the opposite direction makes the distance between the front and rear positioning posts 7 smaller, which is convenient for positioning the smaller end cover, thus improving the applicability of the device.

[0029] To facilitate the fixing of the base plate 1, two fixing plates 2 are installed on the left and right ends of the base plate 1, which are symmetrically distributed front and back.

[0030] Based on the above solution, since there will be flying debris during processing, in order to prevent the debris from flying into the workers, a baffle 18 is installed at the middle of the upper end of the circular plate 3. The baffle 18 is a transparent plate.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
