Description

Technical Field

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

[0002] An electric motor consists of two parts: a rotor and a stator. In the processing of some larger motors, the end face and the side face of the motor need to be processed separately. In order to facilitate the processing operation, the motor needs to be switched between vertical and horizontal positions so that the processing surface is always on the upper side.

[0003] Currently, the workpiece orientation is typically adjusted manually during motor machining, requiring multiple people to move the motor housing. This traditional method has significant drawbacks: manual turning makes it difficult to guarantee positioning accuracy, and repeated handling can easily cause bumps and damage to the motor end face or sides, affecting the assembly accuracy of subsequent machined surfaces; manual turning cannot achieve standardized angle control, resulting in poor consistency between different batches of workpieces, especially when multi-angle step-by-step machining is required, where operators need to repeatedly adjust the workpiece position, reducing production efficiency and increasing labor intensity. Therefore, a turning device for motor machining is proposed. Utility Model Content

This method requires multiple operators to move the motor housing and flip it, which has significant drawbacks: manual flipping makes it difficult to guarantee positioning accuracy, and repeated handling can easily cause damage to the motor end face or side, affecting the assembly accuracy of subsequent machining surfaces; manual flipping cannot achieve standardized angle control, resulting in poor consistency between different batches of workpieces, especially when multi-angle step-by-step machining is required, necessitating repeated adjustments to the workpiece position, reducing production efficiency and increasing labor intensity.

[0026] Example 1

[0027] In current technology, the workpiece posture is usually adjusted by manual flipping during motor processing. This requires multiple people to work together to move the motor housing and flip it. This traditional method has obvious drawbacks: manual flipping is difficult to guarantee positioning accuracy, and repeated handling can easily cause bumps and damage to the end face or side of the motor, affecting the assembly accuracy of subsequent processed surfaces; manual flipping cannot achieve standardized angle control, resulting in poor consistency in the processing of different batches of workpieces. Especially when multi-angle step-by-step processing is required, operators need to repeatedly adjust the position of the workpiece, which reduces production efficiency and increases labor intensity.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a flipping device for motor processing, including a fixed frame 1 and a worktable 3. A box 2 is fixedly connected to one side of the fixed frame 1, a positioning clamping component 4 is provided on the top of the worktable 3, and a processing flipping component 5 is provided inside the box 2.

[0029] The positioning and clamping assembly 4 includes an L-shaped positioning frame 41, two pressure sensors 45, and two cylinders 42. The L-shaped positioning frame 41 is fixed at the intersection of the two adjacent sides of the worktable 3. The two cylinders 42 are arranged adjacently along the remaining two sides of the worktable 3. A connecting rod 48 is fixedly connected to the output end of the cylinder 42, and a push plate 43 is fixedly connected to the top of the connecting rod 48. A clamping plate 44 is fixedly connected to one side of the push plate 43. The inner side of the L-shaped positioning frame 41 forms a right-angled reference plane. The drive axes of the two cylinders 42 are perpendicular to each other, forming an L-shaped drive array. The two clamping plates 44 and the L-shaped positioning frame 41 form a closed square clamping groove, realizing zero-load clamping of the motor. For rapid positioning and clamping in the early stage of part processing, the top of the worktable 3 has two through slots 47 that are adapted to the connecting rod 48. The connecting rod 48 is slidably connected in the through slots 47, so that the connecting rod 48 slides in a straight line along the through slots 47. Pressure sensors 45 are provided on the inner side of the two clamping plates 44 facing the L-shaped positioning frame 41. The clamping surface of the clamping plate 44 is parallel to the right angle reference plane of the L-shaped positioning frame 41, which can quickly clamp motor parts of different models or shapes. Controllers 46 are installed on the adjacent two sides of the worktable 3. The two controllers 46 are electrically connected to the two cylinders 42 and the pressure sensors 45 for synchronous adjustment of the stroke of the two cylinders 42.

[0030] The working principle or structural principle is as follows: First, the motor part is placed on the worktable 3 with one side pressed against the right-angle reference surface of the L-shaped positioning frame 41. Then, the controller 46 activates two cylinders 42, pushing the connecting rod 48 to move linearly along the through groove 47, causing the push plate 43 and clamping plate 44 to move closer to the part. The pressure sensor 45 detects the clamping force in real time and feeds the data back to the controller 46. When the pressure value received by the pressure sensor 45 is greater than the set threshold for more than 3 seconds, the controller 46 controls the cylinder 42 to close. Finally, the two clamping plates 44 and the L-shaped positioning frame 41 form a three-point positioning square clamping groove, completing the adaptive clamping of parts of different sizes. The entire process ensures positioning accuracy and clamping stability. The pressure sensor 45 is a PT124G-210 manufactured by Shanghai Zhaohui Pressure Instrument Co., Ltd., and the controller 46 is an AI-708P manufactured by Xiamen Yudian Automation Technology Co., Ltd. Since the structure and operating principle of these models are existing technologies, their structure and operating principle will not be described in detail here.

[0031] Example 2

[0032] The processing and flipping assembly 5 includes two connecting frames 58 and a motor 51. The motor 51 is fixedly installed on one side of the housing 2. An annular slide rail 6 is fixedly connected to the side wall of the fixed frame 1. The connecting frame 58 is rotatably connected within the annular slide rail 6. The first rotating shaft 56 is supported by a deep groove ball bearing. The connecting frame 58 is radially positioned by the annular slide rail 6. A sector gear 53 is fixedly connected to the output end of the motor 51. A ratchet 52 that meshes with the sector gear 53 is fixedly connected to one side of the connecting frame 58 via the first rotating shaft 56. A spring 55 is fixedly connected to the inner side wall of the housing 2. A ratchet insert 54 is fixedly connected to one end of the spring 55. The connecting frame 58... The ratchet 52 is rotatably connected to the inside of the fixed frame 1 via the first rotating shaft 56 and is symmetrically fixed on both sides of the worktable 3. The rim of the ratchet 52 has 36 teeth evenly distributed. The sector gear 53 has only one driving tooth, which intermittently meshes with the 36 involute teeth of the ratchet 52. Each rotation of the sector gear 53 drives the ratchet to rotate precisely 10 degrees. The ratchet insert 54 is elastically pressed against the side of the teeth of the ratchet 52 by the spring 55. The ratchet insert 54 is rotatably connected to the inside of the housing 2 via the second rotating shaft 57. The contact surface of the ratchet insert 54 is designed with an inclination angle of 5° to ensure that the ratchet 52 can self-lock when the spring 55 is pressed to prevent the ratchet 52 from reversing.

[0033] The working principle or structural principle is as follows: After the motor parts are fixed and clamped by the positioning and clamping assembly 4, when flipping is required for processing, the motor 51 drives the sector gear 53 to rotate. When a single tooth of the sector gear 53 meshes with any of the 36 teeth of the ratchet 52, it drives the ratchet 52 to rotate 10°. The ratchet 52 drives the connecting frame 58 to rotate within the annular slide rail 6 through the first rotating shaft 56, thereby driving the worktable 3 to flip. The ratchet insert 54, under the action of the spring 55, always presses against the tooth surface of the ratchet 52 to prevent reverse rotation. After the sector gear 53 completes one revolution, the single tooth disengages, and the ratchet insert 54 locks into the next tooth gap position of the ratchet 52. This process is repeated to achieve the intermittent indexing movement of the worktable 3, which is precisely flipped by 10° each time. The motor 51 is a model CLJSJ-CH02 manufactured by Kunshan Taiya Electromechanical Technology Co., Ltd. Since the structure and operating principle of this model are existing technologies, their structure and operating principle will not be described in detail here.

[0034] In summary, firstly, a three-point positioning is formed by the L-shaped positioning frame 41 and the clamping plate 44 driven by two cylinders 42. The pressure sensor 45 monitors the clamping force in real time. When the pressure exceeds the threshold for 3 seconds, adaptive clamping is completed. Then, the motor 51 drives the single-tooth sector gear 53 to drive the 36-tooth ratchet 52 to rotate 10° every time. The first rotating shaft 56 causes the connecting frame 58 to rotate along the annular slide rail 6. The ratchet insert 54 is prevented from reversing under the action of the spring 55, realizing the precise intermittent flipping of the worktable 3. The whole process realizes automated positioning and precise indexing processing.
