Description

Technical Field

[0001] This utility model relates to a hole punching machine, and more particularly to a turning device for a hole punching machine for magnetic materials. Background Technology

[0002] Magnetic materials are rare materials that are both hard and brittle. During the production of magnetic materials, due to the special nature of the material, it will break when it is penetrated in one operation. Only half of the material can be processed before it is turned around to process the remaining part. Therefore, after completing one process, the workpiece often needs to be rotated 180 degrees (commonly known as "turning around") in order to process the remaining part.

[0003] Existing turning devices typically use servo motors or stepper motors, connected to a rotary actuator via a reducer to achieve workpiece flipping. This motor-driven approach has several prominent problems:

[0004] The cost is high, as servo motors, drivers, controllers, and precision reducers are all expensive, especially in situations where multiple workstations need to turn around simultaneously, where the cost can increase exponentially.

[0005] The control system is complex and requires professional electrical engineers for programming and debugging. It also has relatively high technical requirements for maintenance personnel.

[0006] The bulky structure, with the motor and reducer occupying a large installation space, makes the overall equipment less compact.

[0007] Synchronization is difficult. For multi-station synchronous flipping applications, multiple motor systems are required and their movements must be precisely synchronized. This further increases the complexity and cost of control, or requires complex mechanical transmission structures such as synchronous belts and synchronous shafts.

[0008] Therefore, the market needs a turning device that is simple in structure, low in cost, easy to control, and easy to achieve synchronous operation of multiple workstations. Utility Model Content

[0009] The technical problem to be solved by this utility model is to overcome the defects of existing motor drive schemes, such as high cost, complex control, and bulky structure, and to provide a magnetic material hole-punching machine turning device that is compact, low cost, small size, and has good performance.

[0010] This utility model provides a turning device for a magnetic material hole punching machine, which includes:

[0011] Base 1;

[0012] The lifting seat assembly includes a lifting seat 4 that is vertically slidably mounted on the side wall of the base 1 and a lifting drive mechanism 3 for driving the lifting seat 4 to rise and fall;

[0013] The turning assembly 8 includes a main shaft 81 that is vertically set and rotatably mounted on the lifting seat 4 and a receiving seat 83 located at the lower end of the main shaft 81. The side wall of the receiving seat 83 has a receiving hole 830 through it, and the axis of the receiving hole 830 is perpendicular to and intersects the axis of the main shaft 81.

[0014] A turning drive mechanism, used to drive the receiving seat 83 to rotate and achieve turning, includes a gear 84, a rack 6 and a drive device 5. The gear 84 is mounted on the main shaft 81. The rack 6 is horizontally slidably mounted on the lifting seat 4 and meshes with the gear 84. The drive device 5 is mounted on the lifting seat 4 and its output end is connected to the rack 6, used to drive the rack 6 to slide between the first end and the second end and drive the main shaft 81 to rotate.

[0015] Furthermore, the rotation angle of the main shaft 81 is 180 degrees, and when the rack 6 is at the first end and the second end, the axis of the receiving hole 830 is perpendicular to the moving direction of the rack 6.

[0016] Furthermore, there are multiple turning assemblies 8 arranged sequentially along the length of the lifting seat 4. The rack 6 is parallel to the length of the lifting seat 4 and simultaneously meshes with each of the gears 84, and can drive each of the turning assemblies 8 to rotate synchronously.

[0017] Furthermore, it also includes a limiting component for limiting the travel of the rack 6, the limiting component including a contact block connected to the rack 6 and a limiting block 44 mounted on the lifting seat 4 and corresponding to the contact block.

[0018] Furthermore, the limiting block 44 is equipped with one or more of the following: a proximity switch 71, a damper 72, or a limiting bolt, which corresponds to the contact block.

[0019] Furthermore, the lifting seat 4 includes a sliding plate 43 vertically mounted on the base 1, a rack seat 41 mounted on the upper end of the sliding plate 43, and a support seat 42 mounted on the side wall of the sliding plate 43. The rack seat 41 has a horizontally opened sliding hole 410. The rack 6 is installed in the sliding hole 410 and can slide. The turning assembly 8 is mounted on the support seat 42.

[0020] Furthermore, a drive block 61 is installed on the side wall of the rack 6, and a strip hole 411 is opened on the side wall of the sliding hole 410 to allow the drive block 61 to pass through and provide it with a moving space. The drive block 61 is connected to the drive device 5 and serves as a contact block of the limiting component.

[0021] Furthermore, the bottom surface of the receiving hole 830 is V-shaped and can achieve automatic centering.

[0022] Furthermore, the support base 42 is a vertically arranged strip structure. The side wall of the support base 42 is provided with an upper support 421 and a lower support 422. The main shaft 81 is rotatably mounted on the upper support 421, and the receiving seat 83 is rotatably mounted on the lower support 422. The main shaft 81 and the receiving seat 83 are connected by a coupling 82, which is located between the upper support 421 and the lower support 422.

[0023] Furthermore, the turning assembly 8 is located between the base 1 and the lifting seat, and the drive device is installed on the top of the lifting seat.

[0024] Furthermore, the driving device is a cylinder, an electric actuator, or a motor. When it is a motor, the output end of the motor is provided with a driving gear that meshes with the rack.

[0025] Compared with the prior art, the present invention has the following significant advantages:

[0026] With its simplified structure and low cost, it replaces expensive servo motors, drivers, and reducers with a simple drive unit (cylinder, electric actuator, or motor gear) and rack and pinion mechanism, greatly simplifying the mechanical structure and control system and significantly reducing manufacturing costs.

[0027] It is reliable in operation, easy to control, and the turning angle is precisely limited by the rack stroke and the gear module. It has high repeatability and requires no complicated programming or debugging.

[0028] It has good multi-station synchronization. For multi-station applications, only a sufficiently long rack needs to be used to mesh with the gears of all stations at the same time. The rack is then driven by the drive unit to achieve perfect mechanical synchronization of all turning assemblies, solving the problem of difficult and costly multi-motor synchronous control.

[0029] With its compact structure and small size, the linear layout of the drive unit and rack is more compact than the combination of motor and reducer, which is conducive to the miniaturization and weight reduction of the equipment.

[0030] Maintenance is convenient, as all pneumatic components are standard parts with good interchangeability. Maintenance and replacement are simple and quick, reducing later maintenance costs and the technical requirements for personnel. Attached Figure Description

Detailed Implementation

[0039] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0040] See Figures 1-7 This utility model provides a turning device for a magnetic material hole punching machine, which includes a base 1, a lifting seat assembly, a turning assembly 8, and a turning drive mechanism.

[0041] The base 1 serves as the main installation body, with guide rails 11 vertically installed on both sides.

[0042] The lifting seat assembly includes a lifting seat 4 and a lifting drive mechanism 3. The lifting seat 4 is vertically slidably mounted on the side wall of the base 1 via a guide rail 11. The lifting drive mechanism 3 is used to drive the lifting seat 4 to rise and fall. When rising, it is used to receive the magnetic material to be processed; when falling, it is located at the processing station, where the magnetic material is ejected into the chuck 2 of the machine tool through other ejection structures. The lifting drive mechanism 3 includes a motor and a lead screw 31 located at the output end of the motor. The lead screw 31 is threadedly connected to the lifting seat 4. The motor is a stepper motor or a servo motor.

[0043] The turning assembly 8 is mounted on the lifting seat 4 and can move up and down with the lifting seat. The turning assembly 8 includes a vertically arranged main shaft 81, which is rotatably mounted on the lifting seat 4. A receiving seat 83 is fixed at the lower end of the main shaft 81. A receiving hole 830 is passed through the side wall of the receiving seat 83. The axis of the receiving hole 830 is perpendicular to and intersects the axis of the main shaft 81, and is used to support the workpiece so that the cylindrical workpiece is in a horizontal state.

[0044] The turning drive mechanism includes a gear 84, a rack 6, and a drive device 5. The gear 84 is fixedly mounted on the main shaft 81, and the rack 6 is horizontally slidably mounted on the lifting seat 4. The rack meshes with the gear 84. The drive device 5 is horizontally mounted on the lifting seat 4, and its output end is connected to the rack 6. It is used to drive the rack 6 to slide between the first end and the second end, thereby driving the main shaft 81 to rotate, and finally driving the receiving seat 83 to rotate, thus realizing the turning.

[0045] In this application, the driving device is a cylinder, an electric actuator, or a motor. When it is a motor, a drive gear meshing with a rack is provided at the output end of the motor to drive the rack to move. Preferably, it is a cylinder.

[0046] In this application, pneumatic and mechanical transmissions replace traditional motor drives. First, costs are significantly reduced; the price of the drive unit and rack and pinion is far lower than a combination of servo motors, drivers, and reducers. Second, control is extremely simple, requiring only a simple pneumatic solenoid valve, eliminating the need for complex programming and debugging, thus reducing the demands on technical personnel. Finally, the structure is simpler and more compact, with high reliability and easy maintenance.

[0047] To improve space utilization, the turning assembly 8 in this application is located between the base 1 and the lifting seat, while the drive unit is installed on top of the lifting seat; the turning assembly 8 and its drive mechanism are arranged in the inner space between the base 1 and the lifting seat 4; the space utilization is high and the structure is compact. This layout makes full use of the inherent structural gaps of the equipment, avoids components protruding outwards, makes the overall external outline of the device simpler, and reduces the size of the equipment.

[0048] In this embodiment, the rotation angle of the main shaft 81 is 180 degrees. Simultaneously, when the rack 6 is at the first and second ends, the axis of the receiving hole 830 is perpendicular to the direction of movement of the rack 6. That is, before and after turning around, the axis of the receiving hole 830 is perpendicular to the direction of movement of the rack, which facilitates the arrangement of this application in the overall equipment. The 180-degree flip (turn) angle is rigidly limited by the mechanical stroke, resulting in high repeatability and no cumulative error. Furthermore, it facilitates automated collaboration, and the fixed starting and ending postures greatly simplify the setup of components such as robotic arms at upstream and downstream workstations.

[0049] In this application, the bottom surface of the receiving hole 830 is V-shaped, which can realize the automatic centering of cylindrical magnetic materials. When a ring-shaped or cylindrical workpiece is placed in, the V-shaped inclined surface will naturally guide the workpiece to slide to the lowest center line, eliminating the need for precise placement, improving the error tolerance and success rate of feeding, and reducing the precision requirements of upstream processes.

[0050] To improve work efficiency, multiple turning assemblies 8 are used in this application and are arranged sequentially along the length of the lifting seat 4. In this embodiment, multiple assemblies are arranged at equal intervals, preferably 3-4. Simultaneously, the rack 6 is parallel to the length of the lifting seat 4 and meshes with each gear 84, driving each turning assembly 8 to rotate synchronously. This achieves perfect mechanical synchronization. Compared to multi-motor solutions that require complex electrical control for barely achieving synchronization, this solution ensures absolute synchronization of the movements of all turning assemblies 8 through a single mechanical component, without any delay or error. Furthermore, the cost advantage is further amplified; regardless of the number of workstations, only one drive source (drive device) is needed, greatly saving costs.

[0051] To ensure operational accuracy, this application also includes a limiting component for limiting the travel of the rack 6. This limiting component includes a contact block and a limiting block 44. The contact block is connected to the rack 6 and moves with it. The limiting block 44 is mounted on the lifting seat 4, corresponding to the contact block, and the contact block and limiting block 44 cooperate to achieve limiting. In this embodiment, a proximity switch 71, a damper 72, or a limiting bolt corresponding to the contact block is installed on the limiting block 44. This enables precise monitoring and control of the rack 6's travel. The mechanical limiting block provides the final physical boundary, preventing abnormal drive device malfunctions that could lead to overtravel and damage to the equipment. The proximity switch provides an electrical signal indicating the rack is in position or at its original position (i.e., the first and second ends) to the main control system, facilitating further program operations and achieving closed-loop control. The damper absorbs impact energy at the end of the travel, avoiding rigid collisions, making the turning action smoother, reducing vibration and noise, and extending the equipment's service life. The limiting bolt allows for rapid travel adjustment, which is convenient and effortless.

[0052] Specifically, the lifting seat 4 includes a sliding plate 43, a rack seat 41, and a support seat 42. The sliding plate 43 is a vertical plate that slides vertically onto the base 1. The rack seat 41 is a strip-shaped structure that is horizontally mounted on the upper end of the sliding plate 43. A horizontal sliding hole 410 is provided on the rack seat 41, and the rack 6 is installed in the sliding hole 410, enabling horizontal sliding. The number of support seats 42 is the same as that of the turning assembly 8. They are mounted on the side wall of the sliding plate 43, and the turning assembly 8 is mounted on the support seat 42. It is easy to process and assemble, and the sliding hole provides precise guidance for the rack, ensuring its meshing accuracy with the gear.

[0053] The support base 42 is a vertically arranged strip structure. An upper support 421 and a lower support 422 are provided on the side wall of the support base 42. The upper end of the main shaft 81 is rotatably mounted on the upper support 421 via a bearing, and the upper end of the receiving seat 83 is rotatably mounted on the lower support 422 via a bearing. The two are coaxial, and the lower end of the main shaft 81 is connected to the upper end of the receiving seat 83 via a coupling 82 located between the upper support 421 and the lower support 422. The turning assembly 8 adopts a split double-support structure. The main shaft 81 and the receiving seat 83 are connected by a coupling 82 and are provided with rotational support by the upper support 421 and the lower support 422 respectively, which significantly improves the rigidity and stability of the rotation system. The double support design effectively resists the radial force and bending moment generated during rotation, avoids the shaking and deflection that may occur in a single-support cantilever structure, and ensures the smoothness during high-speed turning and the accuracy of long-term operation. At the same time, the use of coupling 82 also facilitates installation, commissioning and later maintenance, and can reduce the overall structural volume.

[0054] In this embodiment, a drive block 61 is installed on the side wall of the rack 6, and a strip-shaped hole 411 is formed on the side wall of the sliding hole 410. The strip-shaped hole 411 allows the drive block 61 to pass through and provides it with movement space. The drive block 61 is connected to the drive device 5, serving as the connection end with the drive device. At the same time, the drive block serves as a limiting component, i.e., a contact block. This effectively solves the motion interference problem of the drive connector, making the overall structure more compact and regular. In this embodiment, the strip-shaped hole is formed at the front end of the rack seat. The drive block 61 includes a first connecting block 611 and a second connecting block 612. The first connecting block 611 is located in the strip-shaped hole and is fixedly connected to the rack. The second connecting block 612 is installed at the end of the first connecting block 611. It is vertically arranged, and its rear end is connected to the output end of the drive device (cylinder or electric push rod). Its two sides serve as limiting surfaces, forming a limiting structure, i.e., a contact block, used to contact the damper or limiting bolt and to trigger the proximity switch.

[0055] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
