Description

Technical Field

[0001] The utility model relates to the technical field of a BMC plastic-sealed motor stator nut lifting device, in particular to a BMC plastic-sealed motor stator nut feeding, limiting and lifting workpiece. Background Art

[0002] A plastic-sealed motor refers to a motor manufactured by using a plastic-sealing technology. A material lifting driving mechanism is used to transport materials and is applied to the automated assembly production lines of various industries. A lifting mechanism is used to lift nuts on the production line of the plastic-sealed motor.

[0003] For example, the publication number CN218114890U discloses a material lifting driving mechanism that improves the stability and reliability of material lifting operations. A material lifting driving mechanism includes: a housing; a driving component disposed at one end of the housing; a ball screw, the ball screw is connected to the driving component; a lead screw nut sleeved outside the ball screw; at least two guide shafts, the guide shafts are evenly distributed circumferentially around the central axis of the ball screw, each guide shaft is respectively connected to the housing, and the central axis of each guide shaft is parallel to the central axis of the ball screw; a connecting block provided with a first through hole and a second through hole, the lead screw nut is sleeved in the first through hole and fixedly connected to the connecting block, and the guide shaft is inserted into the second through hole and slidably connected to the connecting block; a lifting member, one end of the lifting member is fixedly connected to the connecting block, and the other end of the lifting member is slidably connected to the housing.

[0004] However, in the prior art, the lifting device lacks a limiting structure for the nut, and the traditional limiting structure is prone to completely fixing the nut, resulting in the need to add an additional step of releasing the nut later. In the process of lifting the nut without a limiting structure, not only is the nut prone to rotate, but also the problem of dislocation is likely to occur during the lifting process, resulting in the nut not being able to be quickly lifted to a fixed position. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems existing in the prior art that in the process of lifting the nut without a limiting structure, not only is the nut prone to rotate, but also the problem of dislocation is likely to occur during the lifting process, and to propose a BMC plastic-sealed motor stator nut feeding, limiting and lifting workpiece.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A BMC plastic-sealed motor stator nut feeding, limiting and lifting workpiece, including a support plate, a first electric cylinder is fixedly installed on one side of the support plate, and a lifting assembly is slidably connected to one side of the first electric cylinder;

[0007] The jacking assembly includes an adapter plate, a second electric cylinder, a transfer block, and a supporting rod. The adapter plate is fixedly installed on one side of the second electric cylinder. The transfer block is fixedly installed at one end of the piston rod of the second electric cylinder. One end of the supporting rod is fixedly connected to the inside of the transfer block. A tension spring is fixedly installed inside the supporting rod. The top of the tension spring is fixedly connected to a docking rod, and the docking rod is slidably connected inside the supporting rod.

[0008] Preferably, one end of the piston rod of the first electric cylinder is fixedly connected to a movable plate, and a guide rail is fixedly installed on the upper surface of the movable plate.

[0009] Preferably, a slider is slidably connected to the upper surface of the guide rail, and a limiting piece is fixedly installed on the upper surface of the slider.

[0010] Preferably, a bearing plate is fixedly installed on the top of the support plate, and a positioning groove is formed on the top of the bearing plate.

[0011] Preferably, a triangular reinforcement plate is fixedly installed at the junction of the support plate and the bearing plate, and the triangular reinforcement plate is located on the lower surface of the bearing plate.

[0012] Preferably, a through hole is formed inside the bearing plate, and the through hole is located directly above the docking rod.

[0013] Preferably, the limiting pieces are located on both sides of the positioning groove.

[0014] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0015] 1. In the present utility model, by installing a second electric cylinder on the side of the first electric cylinder, the second electric cylinder contacts the nut through the docking rod inside the supporting rod. The size of the docking rod is small and can be inserted into the inside of the supporting rod. At the same time, its top is set to be conical and can enter the nut. By being inserted into the nut, sufficient friction is generated, so as to prevent the nut from rotating during the process of jacking the nut, playing a role in improving the stability of the nut. And the existence of the supporting rod can also determine the movement route of the nut and prevent the problem of dislocation.

[0016] 2. In the present utility model, by setting a movable plate at the end of the piston rod of the first electric cylinder and installing a guide rail on the surface of the movable plate, two limiting pieces can move along the direction of the guide rail through the slider and contact the straight edges at the edge of the hexagonal nut, completing the limitation of the nut and playing a role in assisting to improve the stability of the nut.

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides a BMC plastic-encapsulated motor stator nut feeding limit jacking type workpiece, comprising a support plate 1, a first electric cylinder 2 is fixedly mounted on one side of the support plate 1, and a jacking assembly 3 is slidably connected to one side of the first electric cylinder 2;

[0025] The lifting assembly 3 includes a connecting plate 31, a second electric cylinder 32, an adapter block 33 and a support rod 34. The connecting plate 31 is fixedly installed on one side of the second electric cylinder 32, the adapter block 33 is fixedly installed on one end of the piston rod of the second electric cylinder 32, one end of the support rod 34 is fixedly connected to the inside of the adapter block 33, a tension spring 35 is fixedly installed inside the support rod 34, a docking rod 36 is fixedly connected to the top of the tension spring 35, and the docking rod 36 is slidably connected to the inside of the support rod 34, a bearing plate 5 is fixedly installed on the top of the support plate 1, a positioning groove 10 is provided on the top of the bearing plate 5, a triangular reinforcement plate 4 is fixedly installed at the junction of the support plate 1 and the bearing plate 5, the triangular reinforcement plate 4 is located on the lower surface of the bearing plate 5, a through hole is provided inside the bearing plate 5, and the through hole is located directly above the docking rod 36.

[0026] The specific configuration and function of this embodiment are described in detail below. On the production line of BMC plastic-sealed motor stators, this device is used to convey nuts. The first electric cylinder 2 is fixedly mounted on the side of the support plate 1 and is located below the load-bearing plate 5. When in use, the lifting assembly 3 located on the side of the first electric cylinder 2 is used to lift the nut. The hexagonal nut is conveyed to the positioning groove 10 of the load-bearing plate 5 by the conveying mechanism, and then the lifting assembly 3 lifts the hexagonal nut in the positioning groove 10 upwards.

[0027] The second electric cylinder 32 pushes the adapter block 33 upwards through the piston rod. During the movement of the adapter block 33, the supporting rod 34 inside it passes through the through hole of the bearing plate 5, so that the docking rod 36 and the hexagonal nut are in contact with each other. The top of the docking rod 36 is set to be conical and can enter the nut, so that sufficient friction can be generated to prevent the nut from rotating, thereby improving the stability of the nut.

[0028] The docking rod 36 is fixedly connected to the supporting rod 34 via the tension spring 35 , so that the docking rod 36 can be pressed into the supporting rod 34 , ensuring that the lifting assembly 3 can contact nuts of different calibers.

[0029] Embodiment 2: Figure 2 and Figure 3 As shown, one end of the piston rod of the first electric cylinder 2 is fixedly connected to a movable plate 6, a guide rail 7 is fixedly installed on the upper surface of the movable plate 6, a slider 9 is slidably connected to the upper surface of the guide rail 7, a limit plate 8 is fixedly installed on the upper surface of the slider 9, and the limit plates 8 are located on both sides of the positioning groove 10.

[0030] The effect achieved by the whole embodiment is that the height of the movable plate 6 is controlled by the first electric cylinder 2 to adjust the height of the limit plate 8. The limit plate 8 is located on both sides of the positioning groove 10. When the first nut is placed in the positioning groove 10, the limit plate 8 is moved by the slider 9 to make the limit plate 8 move to contact the straight edge at the edge of the hexagonal nut. The moving route of the slider 9 is determined by the guide rail 7.

[0031] Subsequently, during the process of jacking the nut on the jacking assembly 3, the first electric cylinder 2 also pushes the movable plate 6 upward. When the limiting piece 8 contacts the nut and cooperates with the supporting rod 34, the limiting of the nut can be completed, playing a role in improving the stability of the nut.

[0032] Usage method and working principle of this device: During the production of the BMC plastic-encapsulated motor stator, the hexagonal nut is first conveyed by the conveying mechanism into the positioning groove 10 of the bearing plate 5, and then the limiting piece 8 is moved along the direction of the guide rail 7 to make the limiting piece 8 contact the straight edge at the edge of the hexagonal nut;

[0033] The second electric cylinder 32 and the first electric cylinder 2 are started simultaneously. The second electric cylinder 32 pushes the adapter block 33 upward through the piston rod, so that the supporting rod 34 passes through the through hole of the bearing plate 5 and contacts the bottom of the nut, and the docking rod 36 located inside the supporting rod 34 will be inserted into the hexagonal nut, using the frictional force between the docking rod 36 and the nut to prevent the nut from rotating;

[0034] The first electric cylinder 2 pushes the movable plate 6 upward. The cooperation between the limiting piece 8 and the supporting rod 34 can complete the limiting of the nut, playing a role in improving the stability of the nut.

[0035] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
