Description

Technical Field

[0001] The utility model relates to the technical field of motor production and processing, in particular to a drilling device for motor production and processing. Background Technique

[0002] A motor is a device that converts electrical energy into mechanical energy. Its working principle is that the magnetic field acts on the current to make the motor rotate. Motors are divided into DC motors and AC motors according to the different power supplies used. During the production and processing of motors, a drilling device is usually used to complete the drilling operation on parts.

[0003] The existing drilling device includes clamping plates and a motor. A drill bit is provided at the output end of the motor. When drilling operation is required, the parts to be drilled are placed between the two clamping plates, and the parts are clamped and fixed between the clamping plates by moving the clamping plates. The motor is started and the drill bit moves downward to complete the drilling operation on the surface of the parts.

[0004] However, when the existing drilling device is performing drilling operation, the parts are in a suspended state between the clamping plates. When the drill bit rotates and drills downward, it will squeeze the plane of the parts, easily causing depressions around the holes of the parts and affecting the surface flatness of the parts. Therefore, a drilling device for motor production and processing is proposed for the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve the problem that extrusion depressions cannot be prevented during drilling, the utility model proposes a drilling device for motor production and processing.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: A drilling device for motor production and processing according to the utility model includes a workbench. A moving plate is arranged below the workbench. A threaded rod is rotatably installed on the workbench, and the threaded groove of the threaded rod is rotatably matched on the moving plate. A first turntable is fixed at the top of the threaded rod. A first limit post is fixed at the bottom of the workbench, and the first limit post slidably penetrates through the moving plate. A fixed disk is fixed on the moving plate. A chute is opened on the fixed disk, and the chute is arranged in a "hexagonal" structure. A support plate is arranged on the fixed disk, and there are six support plates. Each support plate is respectively arranged on each side of the "hexagonal" structure of the chute. A slider is fixed at the bottom of the support plate, and the slider is slidably installed in the chute. By providing support around the drill hole through the support plate, the support function of the parts during drilling is realized, the extrusion depression of the parts during drilling is avoided, and the surface flatness of the parts is ensured.

[0007] Preferably, the support plate is arranged in an "equilateral triangle" structure, and each adjacent support plate is attached to each other, realizing the function of cooperating with each other between the support plates to form a middle hole.

[0008] Preferably, a gear disc is arranged on the outer side of the fixed disc, and the gear disc is rotatably arranged on the moving plate. A guide rod is fixed on the support plate, and a guide plate is fixed on the gear disc. The guide rod and the guide plate are in a matching and clamping structure. Through the structural arrangement of the relative movement of the support plate, the function that the support plate can support the periphery of the holes drilled by different drill bits is realized, avoiding the problems of damage to the support plate caused by too large holes or ineffective support of the support plate caused by too small holes, and ensuring the effectiveness of the device.

[0009] Preferably, a fixed plate is fixed at the bottom of the workbench. A worm is rotatably arranged on the fixed plate, and the worm is meshed with the teeth of the gear disc. A second turntable is fixed at one end of the worm, realizing the function of driving the gear disc to rotate by the rotation of the worm.

[0010] Preferably, a hole is formed in the workbench. A bidirectional threaded screw rod is rotatably arranged in the hole of the workbench. Clamping plates are respectively rotatably installed on the bidirectional threaded grooves of the bidirectional threaded screw rod. A second limit post is slidably penetrated through the two clamping plates, and the second limit post is fixed on the workbench, realizing the function of clamping and fixing the clamping plates.

[0011] Preferably, the bidirectional threaded screw rod passes through the workbench and is fixedly connected with a rotary handle. A drilling mechanism is arranged on the workbench in a matching manner, realizing the function of drilling the device.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. When the drill bit rotates and drills downwards, it will exert extrusion on the plane of the component, which is likely to cause depression around the punched hole of the component, affecting the surface flatness of the component. By moving the moving plate upwards, driving the fixed plate upwards, through the matching and clamping arrangement of the sliding groove and the sliding block, driving the support plate upwards, so that the top of the support plate supports the bottom of the component. Since a certain hole is formed between the support plates, the support plate will not be damaged during the drilling process. Through the support arrangement of the support plate around the drill hole, the support function of the component during drilling is realized, avoiding the extrusion depression of the component during drilling, and ensuring the surface flatness of the component.

[0014] 2. During the drilling process of components, different components use drill bits of different sizes. To enable the support plate to support the periphery of the holes drilled by different drill bits, the worm rotates to drive the gear disk to rotate, which in turn drives the guide plate to rotate, causing the support plate to move along one side of the "hexagonal" structure of the sliding groove under the restriction of the slider, realizing the function of adjusting the size of the holes between the support plates, achieving the function that the support plate can support the periphery of the holes drilled by different drill bits, and avoiding the problems of damage to the support plate caused by over-large drilling or ineffective support of the support plate caused by over-small drilling.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1

[0025] Please refer to Figures 1-4 As shown in the figure, a drilling device for the production and processing of a motor includes a workbench 1. A moving plate 2 is arranged below the workbench 1. A threaded rod 3 is rotatably installed on the workbench 1, and the threaded groove of the threaded rod 3 is rotatably arranged on the moving plate 2 in a matching manner. A first turntable 4 is fixed to the top of the threaded rod 3. A first limit post 5 is fixed to the bottom of the workbench 1, and the first limit post 5 slidably penetrates through the moving plate 2. A fixed disk 6 is fixed to the moving plate 2. A chute 7 is formed in the fixed disk 6, and the chute 7 is arranged in a "hexagonal" structure. A support plate 9 is arranged on the fixed disk 6, and there are six support plates 9. Each support plate 9 is respectively arranged on each side of the "hexagonal" structure of the chute 7. A slider 8 is fixed to the bottom of the support plate 9, and the slider 8 is slidably installed in the chute 7. A hole is formed in the workbench 1. A bidirectional threaded screw rod 16 is rotatably arranged in the hole of the workbench 1. Clamping plates 17 are respectively rotatably installed on the bidirectional threaded grooves of the bidirectional threaded screw rod 16. A second limit post 18 slidably penetrates through the two clamping plates 17, and the second limit post 18 is fixed to the workbench 1. The bidirectional threaded screw rod 16 passes through the workbench 1 and is fixedly connected to a rotating handle 19. A drilling mechanism 20 is arranged on the workbench 1 in a matching manner;

[0026] During operation, in the production and processing of electric motors, a drilling device is used to drill holes in flat components. However, in the existing drilling device during the drilling operation, the component is in a suspended state between the clamping plates. When the drill bit rotates and drills downwards, it will exert pressure on the plane of the component, easily causing depressions around the drilled hole of the component and affecting the surface flatness of the component. In order to prevent the component from being squeezed and depressed during drilling, when a flat component needs to be drilled, the component is placed between two clamping plates 17. By rotating the rotating handle 19, the bidirectional threaded screw rod 16 rotates. Under the guidance of the second limiting column 18 by the clamping plate 17, the two clamping plates 17 move towards each other to clamp and fix the component. At this time, rotate the first turntable 4 to make the threaded rod 3 rotate. Under the limitation of the first limiting column 5, the moving plate 2 moves upwards along the threaded rod 3, driving the fixed disk 6 to move upwards. Through the cooperation and clamping setting of the sliding groove 7 and the sliding block 8, the supporting plate 9 is driven to move upwards, so that the top of the supporting plate 9 supports the bottom of the component. At this time, start the drilling mechanism 20 to perform a drilling operation on the component. Since a certain hole is formed between the supporting plates 9, the supporting plates 9 will not be damaged during the drilling process. By using the supporting plates 9 to support the surrounding of the drilled hole, the supporting function of the component during drilling is realized, avoiding the component from being squeezed and depressed during drilling, and ensuring the surface flatness of the component.

[0027] A gear disk 11 is arranged on the outer side of the fixed disk 6, and the gear disk 11 is rotatably arranged on the moving plate 2. A guide rod 10 is fixed on the supporting plate 9. A guide plate 12 is fixed on the gear disk 11, and the guide rod 10 and the guide plate 12 are in a matching and clamping structure. A fixed plate 13 is fixed at the bottom of the workbench 1. A worm 14 is rotatably arranged on the fixed plate 13, and the worm 14 meshes with the teeth of the gear disk 11. A second turntable 15 is fixed on one end of the worm 14. The supporting plate 9 is arranged in an "equilateral triangle" structure, and each adjacent supporting plate 9 is attached to each other;

[0028] During operation, during the drilling process of components, different components use drill bits of different sizes, and the sizes of the drilled holes are also different. In order to enable the support plate 9 to support the periphery of the holes drilled by different drill bits and prevent depressions from occurring around the components during drilling, it is necessary to adjust the size of the holes formed between the support plates 9 to match the size of the drill bit, so that the support plate 9 can effectively support the periphery of the drilled hole. In order to achieve the function of adjusting the size of the holes formed between the support plates 9, when it is necessary to adjust the size of the holes formed between the support plates 9, rotate the second turntable 15 to make the worm 14 rotate. Since the worm 14 meshes with the teeth of the gear disk 11, the gear disk 11 rotates, driving the guide plate 12 to rotate. Since the guide plate 12 and the guide rod 10 are in a cooperating and clamping structure, the guide plate 12 drives the guide rod 10 to move. Since the guide rod 10, the support plate 9 and the slider 8 are fixedly connected, the guide rod 10 drives the slider 8 to move during the movement process. Since the slider 8 can only move in the chute 7, the support plate 9 moves along one side of the "hexagonal" structure of the chute 7 under the restriction of the slider 8. Through the structural setting of the support plate 9, the support plate 9 can adjust the size of the hole between them under the condition of relative movement. When the hole between the support plates 9 matches the size of the drill bit, stop the rotation of the second turntable 15. Through the structural setting of the relative movement of the support plate 9, the function of the support plate 9 to support the periphery of the holes drilled by different drill bits is realized, avoiding the problems of damage to the support plate 9 caused by too large a drill hole or ineffective support of the support plate 9 caused by too small a drill hole, and ensuring the effectiveness of the device.

[0029] Embodiment 2

[0030] Please refer to Figures 5-6 As shown, compared with Embodiment 1, as another implementation manner of the present utility model, a positioning cylinder 21 is fixed on the drilling mechanism 20, and the positioning cylinder 21 is arranged in the cross direction of the drill bit. A pressing plate 22 is arranged below the positioning cylinder 21. A spring 23 is fixed between the positioning cylinder 21 and the pressing plate 22. A telescopic rod 24 is fixed on the pressing plate 22, and the telescopic rod 24 slidably penetrates through the positioning cylinder 21. During operation, when the drilling mechanism 20 moves the drill bit downward for drilling, the pressing plate 22 contacts the component. When the drill bit continues to move downward, the spring 23 is compressed, and the telescopic rod 24 penetrates into the positioning cylinder 21. Through the extrusion function setting of the clamping plate 22, the support plate 9 cooperates with the extrusion function of the clamping plate 22 during the support process, so that the component is fixed between the support plate 9 and the clamping plate 22 during the drilling operation, enhancing the anti-drilling depression function of the support plate 9 and avoiding the extrusion depression of the component during drilling.

[0031] Working principle: During the production and processing of an electric motor, a drilling operation is performed on a flat component using a drilling device. However, in the existing drilling device during the drilling operation, the component is in a suspended state between the clamping plates. When the drill bit rotates and drills downward, it will exert pressure on the plane of the component, easily causing depressions around the drilled hole of the component, affecting the surface flatness of the component. In order to prevent the component from being squeezed and depressed during drilling, when drilling a flat component, place the component between two clamping plates 17. Rotate the rotating handle 19 to rotate the double-threaded screw rod 16. Under the guidance of the second limiting column 18, the two clamping plates 17 move towards each other to clamp and fix the component. At this time, rotate the first turntable 4 to rotate the threaded rod 3. Under the restriction of the first limiting column 5, the moving plate 2 moves upward along the threaded rod 3, driving the fixed disk 6 to move upward. Through the matching and clamping of the sliding groove 7 and the slider 8, the support plate 9 is driven to move upward, so that the top of the support plate 9 supports the bottom of the component. At this time, start the drilling mechanism 20 to perform a drilling operation on the component. Since a certain hole is formed between the support plates 9, the support plates 9 will not be damaged during the drilling process. By supporting the area around the drill hole with the support plates 9, the support function of the component during drilling is realized, avoiding the component from being squeezed and depressed during drilling, and ensuring the surface flatness of the component;

[0032] During the drilling process of components, different components use drill bits of different sizes, and the sizes of the drilled holes are also different. In order to enable the support plate 9 to support the periphery of the holes drilled by different drill bits and prevent depressions from occurring around the components during drilling, it is necessary to adjust the size of the holes formed between the support plates 9 to match the size of the drill bits, so that the support plate 9 can effectively support the periphery of the drilling. In order to realize the function of adjusting the size of the holes formed between the support plates 9, when it is necessary to adjust the size of the holes formed between the support plates 9, rotate the second turntable 15 to make the worm 14 rotate. Since the worm 14 meshes with the teeth of the gear disk 11, the gear disk 11 rotates, driving the guide plate 12 to rotate. Since the guide plate 12 and the guide rod 10 are in a cooperating and clamping structure, the guide plate 12 drives the guide rod 10 to move. Since the guide rod 10, the support plate 9 and the slider 8 are fixedly connected, the guide rod 10 drives the slider 8 to move during the movement. Since the slider 8 can only move in the chute 7, the support plate 9 moves along one side of the "hexagon" structure of the chute 7 under the restriction of the slider 8. Through the structural setting of the support plate 9, the function of adjusting the size of the holes between the support plates 9 is realized under the condition of relative movement. When the size of the holes between the support plates 9 matches the size of the drill bit, stop the rotation of the second turntable 15. Through the structural setting of the relative movement of the support plate 9, the function that the support plate 9 can support the periphery of the holes drilled by different drill bits is realized, avoiding the problems of damage to the support plate 9 caused by too large drilling or ineffective support of the support plate 9 caused by too small drilling, and ensuring the effectiveness of the device.
