Description

Technical Field

[0001] The utility model belongs to the technical field of gear processing, and in particular relates to a high-speed precision punching machine for gear punching. Background Art

[0002] Gears refer to mechanical components with gears on the wheel rim that continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. At the end of the 19th century, the principle of gear cutting and the special machine tools and tools that use this principle to cut gears appeared one after another. With the development of production, the stability of gear operation has been paid attention to. In order to reduce the weight of the gear and make the gear connection more stable, it is necessary to punch holes on the end faces of the gears. However, the existing gear punching device needs to manually rotate and position the workpiece when processing the gear, so as to punch out holes of uniform size.

[0003] In the prior art, for example, the patent application number CN201922282494.8, entitled "A Punching Device for Gear Processing", places the gear sleeve on the fixing column and tightens the fasteners to press and fix the gear on the storage plate, thereby improving the stability of the gear and facilitating subsequent punching operations; after the gear is fixed, the threaded rod is manually rotated, and the slider can slide left and right under the rotation of the threaded rod, thereby driving the punching block to move left and right until the punching block is directly above the corresponding punching hole, and then the punching block can move downward under the action of the hydraulic cylinder and the piston rod to perform the punching work, thereby solving the deficiencies mentioned in the above process;

[0004] However, in the actual processing process, the position of the support cylinder using the new patent relative to the fixed column cannot be adjusted, and through holes with different distances relative to the center of the gear cannot be processed. In addition, the installation between the storage plate and the gear is not very firm, and the gear is likely to rotate with the storage plate, so the through holes processed on the gear are not uniform. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a high-speed precision punching machine for punching gears, which has the effect of processing uniform through holes on gears of different sizes.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-speed precision punching machine for punching gears, comprising a punching machine body, a column is vertically fixed on the upper end of the punching machine body, a punch power device is installed on the top of the column, and a punch is installed on the bottom end of the punch power device, characterized in that a guide workbench is detachably installed on the upper end surface of the punching machine body, a movable seat is movably installed on the upper end surface of the guide workbench, a lower module is driven and installed on the movable seat, a discharge through hole is penetrated on the lower module, an embedded ring matched with the limit groove is fixedly provided at the edge position of the lower module, and a discharge through hole is penetrated on the upper end surface of the lower module;

[0007] The lower module is provided with a discharge through hole located directly below the punch, and an embedded ring matched with the limiting groove is fixedly provided at the edge of the lower module;

[0008] The movable seat platform is provided with a gear transmission structure, which includes a limit plate, a fixed shaft is coaxially fixed at the bottom end of the limit plate, a large gear is coaxially fixed at the bottom end of the fixed shaft, and the fixed shaft passes through the through hole slot and is adapted to rotate with the movable seat platform;

[0009] By installing the gear workpiece on the gear transmission structure and adjusting the position of the movable seat on the guide workbench, the through hole to be processed on the gear workpiece is located directly below the punch. By replacing different lower modules, the discharge through hole can be adapted to process through holes of different sizes and positions.

[0010] Optionally, a spline is fixedly provided at the middle position of the limit plate, a threaded column is vertically fixedly provided at the top of the spline, and a gear limit sleeve is sleeved on the spline;

[0011] A plurality of spline protrusions arranged at equal intervals on the circumference are fixedly provided on the inner side of the gear limiting sleeve, a limiting convex key is fixedly provided on one side of the gear limiting sleeve, the spline protrusion is adapted and slidably connected with the spline, a locking threaded sleeve is threadedly installed on the threaded column, a transmission pinion is meshed on one side of the large gear, and a gear motor is driven and installed at the bottom end of the transmission pinion;

[0012] The output shaft of the gear motor rotates to drive the transmission pinion to rotate, and the transmission pinion and the large gear mesh with each other, thereby driving the large gear to rotate, so that the large gear, fixed shaft, limit plate, thrust spring, threaded column, spline and gear limit sleeve all rotate, thereby driving the gear workpiece to rotate.

[0013] It is worth mentioning that a through hole is provided in the middle of the gear workpiece, and a keyway is provided on one side of the through hole. By adapting the through hole of the gear workpiece to the outer side of the gear limit sleeve and inserting the limit cam into the keyway, the gear workpiece is fixed relative to the gear limit sleeve. Furthermore, a spline cam matched with the spline is provided on the inner side of the gear limit sleeve, so that the gear limit sleeve is limited relative to the limit disk. At the same time, the locking thread sleeve and the threaded column are threadedly locked to fix the gear limit sleeve relative to the limit disk. At the same time, it is convenient to loosen and disassemble the locking thread sleeve to replace different gear limit sleeves, so as to adapt to the processing of different gear workpieces.

[0014] Optionally, a thrust spring is sleeved on the fixed shaft, and the thrust spring is located between the through hole slot and the limiting plate, and the upper end surface of the limiting plate is higher than the upper end surface of the movable seat platform;

[0015] The limit plate, the fixed shaft and the large gear are pushed upward by the provided thrust spring, so that the limit plate extends out of the upper end surface of the moving platform. It is worth noting that the bottom end surface of the gear workpiece and the upper end surface of the limit plate fit each other, and the upper end surface of the limit plate exceeds the upper end surface of the moving platform. Therefore, the bottom end surface of the gear workpiece and the upper end surface of the moving platform are separated from each other. When the gear workpiece rotates, the bottom end surface of the gear workpiece will not rub against the upper end surface of the moving platform, thereby reducing mechanical wear. At the same time, when the punch punches the gear workpiece, the thrust spring is compressed, and the upper end surface of the moving platform and the bottom end surface of the gear workpiece fit each other, so that the moving platform supports the gear workpiece, thereby facilitating the stamping of the gear workpiece.

[0016] Optionally, a magnetic block is fixedly embedded on the lower module at a position close to the axis of the movable seat platform;

[0017] It is convenient to fix the lower module on the mobile platform.

[0018] Optionally, a screw rod with limited rotation connection is installed on the guide workbench, a screw motor is installed at one end of the screw rod for driving, and the screw rod is threadedly connected to the movable seat platform;

[0019] The output shaft of the screw motor rotates to drive the screw to rotate. The screw is threadedly connected to the moving table, thereby driving the moving table to move on the punching machine body, so that the position of the hole to be processed on the gear workpiece is directly opposite to the bottom of the punch, thereby realizing the processing of through holes on different gear workpieces.

[0020] Optionally, a lower mold embedding ring is provided on one side of the movable seat, and a waste outlet groove is fixedly provided on the bottom end of the lower mold block, which is located on the inner side of the lower mold embedding ring and is tilted downward, and the waste outlet groove extends to the edge of the guide workbench;

[0021] It is worth mentioning that the waste formed by punching the gear workpiece with a punch falls downward through the discharge hole, and is tilted downward by the waste discharge chute set up, extending out of the position of the side of the guide workbench, and the end of the waste discharge chute is located directly below the discharge hole, and the waste is discharged through the waste discharge chute to achieve discharge.

[0022] In summary, compared with the prior art, the beneficial effects of this solution are:

[0023] 1. By replacing different gear limit sleeves to fix gear workpieces of different sizes, and by replacing different lower modules and punches and adjusting the movable platform to adapt to the processing of gears of different sizes, the technical problems raised in the technical background are solved.

[0035] The lower module 30 is provided with a discharge through hole 33 located directly below the punch 14, and an embedded ring 31 adapted to the limiting groove 22 is fixedly provided at the edge of the lower module 30;

[0036] The gear transmission structure 40 includes a limit plate 41, a fixed shaft 42 is coaxially fixed to the bottom end of the limit plate 41, a large gear 43 is coaxially fixed to the bottom end of the fixed shaft 42, and the fixed shaft 42 passes through the through hole slot 24 and is adapted to rotate with the movable seat 20;

[0037] By installing the gear workpiece 60 on the gear transmission structure 40 and adjusting the position of the movable seat 20 on the guide workbench 11, the through hole to be processed on the gear workpiece 60 is located directly below the punch 14. By replacing different lower modules 30, the discharge through hole 33 is adapted to process through holes of different sizes and positions.

[0038] In this embodiment, a spline 46 is fixedly provided at the middle position of the limiting plate 41, a threaded column 45 is vertically fixedly provided at the top of the spline 46, and a gear limiting sleeve 50 is sleeved on the spline 46;

[0039] A plurality of spline protrusions 51 arranged at equal intervals on the circumference are fixedly disposed on the inner side of the gear limiting sleeve 50, a limiting convex key 52 is fixedly disposed on one side of the gear limiting sleeve 50, the spline protrusion 51 is adapted to be slidably connected with the spline 46, a locking threaded sleeve 49 is threadedly mounted on the threaded column 45, a transmission pinion 47 is meshedly disposed on one side of the large gear 43, and a gear motor 48 is driven and mounted on the bottom end of the transmission pinion 47;

[0040] The output shaft of the gear motor 48 rotates to drive the transmission pinion 47 to rotate, and the transmission pinion 47 meshes with the large gear 43, thereby driving the large gear 43 to rotate, so that the large gear 43, the fixed shaft 42, the limit plate 41, the thrust spring 44, the threaded column 45, the spline 46 and the gear limit sleeve 50 all rotate, thereby driving the gear workpiece 60 to rotate.

[0041] It is worth mentioning that a through hole is provided in the middle of the gear workpiece 60, and a keyway is provided on one side of the through hole. By adapting the through hole of the gear workpiece 60 to the outer side of the gear limit sleeve 50 and inserting the limit key 52 into the keyway, the gear workpiece 60 is fixed relative to the gear limit sleeve 50. Furthermore, the inner side of the gear limit sleeve 50 is provided with a spline protrusion 51 adapted to the spline 46, so that the gear limit sleeve 50 is limited relative to the limit disk 41. At the same time, the locking thread sleeve 49 and the threaded column 45 are threadedly locked to fix the gear limit sleeve 50 relative to the limit disk 41.

It is worth noting that the bottom end surface of the gear workpiece 60 and the upper end surface of the limit plate 41 are in contact with each other, and the upper end surface of the limit plate 41 exceeds the upper end surface of the movable platform 20. Therefore, the bottom end surface of the gear workpiece 60 and the upper end surface of the movable platform 20 are separated from each other. When the gear workpiece 60 rotates, the bottom end surface of the gear workpiece 60 will not rub against the upper end surface of the movable platform 20, thereby reducing mechanical wear. At the same time, when the punch 14 stamps the gear workpiece 60, the thrust spring 44 is compressed, and the upper end surface of the movable platform 20 and the bottom end surface of the gear workpiece 60 are in contact with each other, so that the movable platform 20 supports the gear workpiece 60, which is convenient for stamping the gear workpiece 60.

[0044] In addition, a magnetic block 32 is fixedly embedded on the lower module 30 at a position close to the axis of the movable seat 20, and the magnetic block 32 is magnetically attached to the movable seat 20;

[0047] The output shaft of the screw motor 26 rotates to drive the screw 25 to rotate. The screw 25 is threadedly connected to the movable seat 20, thereby driving the movable seat 20 to move on the punch body 10, so that the position of the hole to be processed on the gear workpiece 60 is directly opposite to the bottom of the punch 14, thereby realizing the processing of through holes on different gear workpieces 60.

[0048] Example 2: Reference Figure 7-Figure 8 The difference between this embodiment and the first embodiment is that the bottom end of the lower die block 30 is located on the inner side of the lower die embedding ring 21 and is fixedly provided with a waste outlet groove 27 which is tilted downward, and the waste outlet groove 27 extends to the edge of the guide workbench 11;

[0049] It is worth noting that the waste formed by punching the gear workpiece 60 with the punch 14 falls downward through the discharge hole 33, and is tilted downward by the waste discharge chute 27 set up, extending out of the side of the guide workbench 11, and the end of the waste discharge chute 27 is located directly below the discharge hole 33, and the waste is discharged through the waste discharge chute 27 to achieve discharge.
