Description

Technical Field

[0001] This utility model relates to the field of hardware processing equipment technology, and in particular to a central plate rotation drive mechanism for a hardware processing machine. Background Technology

[0002] The working principle of a precision machining center for hardware involves high-precision cutting, forming, or surface treatment technologies, which aim to process metal raw materials into parts that meet strict requirements for size, shape, and surface quality, so as to be suitable for precision assembly on different products.

[0003] Currently, precision machining machines for hardware parts on the market are generally divided into linear stepper type and rotary type. Linear stepper type precision machining machines use a chain as the medium and indexing cams to achieve stepping conveying action. During the chuck conveying process, processing is performed at various workstations. This type of equipment has many chucks, the chain is prone to misalignment, and the processing accuracy is relatively poor. Therefore, rotary type precision machining machines are now more commonly chosen for precision machining of hardware parts.

[0004] Regarding disc-type precision machining machines for hardware, Chinese patent CN201710525911.X discloses a disc-type multi-station pen tip processing device. In this design, the rotation drive of the rotating disc adopts a structure of motor + pulley + worm gear. The worm gear is linked to the output shaft of the first drive motor through a pulley assembly. The rotating disc is provided with protrusions that mesh with the worm gear, and the protrusions are distributed at intervals along the circumference of the rotating disc. The rotation of the worm gear drives the rotating disc to rotate. However, in practical applications, the frequent friction between the worm gear and worm wheel easily leads to wear and the generation of a large amount of heat at their meshing points, resulting in transmission gaps that affect positioning accuracy. Furthermore, the worm gear and worm wheel are prone to elastic deformation under impact loads, resulting in a short service life and failing to meet the requirements for high-speed and stable operation of the equipment, necessitating improvements.

[0039] Detailed implementation plan: See below Figures 1-9This utility model relates to a central plate rotation drive mechanism for a hardware processing machine. The hardware processing machine includes a frame 1 and an upper support frame 2 mounted above the frame 1. The upper support frame 2 is used to support a chassis 4. A rotary support plate 5 and an upper plate 9 are sequentially arranged above the chassis 4. A central plate 6 is rotatably mounted on the rotary support plate 5. A plurality of spaced-apart chuck seats 10 are arranged around the central plate 6. A plurality of spaced-apart processing cutter heads 11 are arranged around the upper plate 9. The central plate rotation drive mechanism includes:

[0040] Gear ring 61 is fixed on the middle plate 6;

[0041] The drive unit 3 includes a servo motor 31 fixed on the upper support frame 2, a shaft assembly linked to the servo motor 31, and a gear 38 mounted on the shaft assembly. The gear 38 is meshed on the gear ring 61.

[0042] The middle plate 6 has a waiting state where it is stopped relative to the upper plate 9. In the waiting state, each chuck 10 is respectively positioned directly below each machining head 11.

[0043] As a preferred embodiment of this example, please refer to Figure 2 and Figure 3 As can be seen, the upper support frame 2 includes a base 21 fixed above the frame 1 and a support column 22 fixed above the base 21. The chassis 4 is installed above the support column 22, and the servo motor 31 is fixedly installed on the base 21.

[0044] Then, in this embodiment, the shaft assembly includes:

[0045] The first shaft 34 is linked to the rotating shaft via the first coupling 33, and the rotating shaft is mounted on the motor shaft of the servo motor 31;

[0046] The second shaft 36 is linked to the first shaft 34 via the second coupling 35, and the gear 38 is fixed to the upper end of the second shaft 36.

[0047] Next, please refer to Figures 1-5 As can be seen, in this embodiment, a first bearing seat 32 is provided on the motor shaft, and a second bearing seat 37 is provided on the second shaft 36. The first bearing seat 32 is fixed on the base 21, and the second bearing seat 37 is fixed on the chassis 4.

[0048] In this embodiment, the servo motor 31 is mounted on the upper support frame 2 via a motor mount. Furthermore, the rotating shaft is also mounted on the motor shaft of the servo motor 31 via a coupling. When the servo motor 31 operates, it drives the rotating shaft, the first shaft 34, and the second shaft 36 to rotate together. Note that the use of multiple couplings here makes the structure of the shaft assembly more stable.

[0049] Furthermore, the arrangement of the first bearing seat 32 on the base 21 and the second bearing seat 37 on the chassis 4 can help make the first shaft 34 and the second shaft 36 on the shaft assembly rotate more stably.

[0050] The working principle of the middle plate rotation drive mechanism: The servo motor 31 works and drives the first shaft 34 and the second shaft 36 to rotate. Since the gear 38 is fixed on the upper end of the second shaft 36, the gear 38 can be driven to rotate. Since the gear 38 meshes on the gear ring 61, and the gear ring 61 is fixed on the middle plate 6, the gear ring 61 and the middle plate 6 can be driven to rotate together.

[0051] Note that in this embodiment, the central plate rotation drive mechanism can drive the central plate 6 to rotate and stop intermittently to enter the processing state (equivalent to switching workstations, the same chuck 10 will stop sequentially under different processing cutters 11). In the processing state, the processing cutter 11 descends and processes the hardware on the chuck 10.

[0052] In this embodiment, the structural design of servo motor 31 + gear 38 and gear ring 61 provides very stable and high-precision driving. The servo motor 31 can precisely control the stopping and starting of the central plate 6, which can meet the high-speed operation of the equipment.

[0053] Then, please see Figure 1 , Figure 4 , Figure 5 and Figure 8 The chassis 4 is provided with a through hole 41 for the shaft assembly to pass through, and the gear ring 61 is an internal gear ring 61, and the gear ring 61 is fixed below the middle plate 6.

[0054] Here, by providing through holes 41 on the chassis 4, the shaft assembly can pass through, thereby making the structure of the equipment more compact and stable.

[0055] Next, please refer to Figures 6-8 As can be seen, the outer periphery of the slewing support plate 5 is provided with a transition groove 51, and the upper part of the middle plate 6 is fixedly provided with a bearing outer ring 62. The bearing outer ring 62 is rotatably installed in the transition groove 51, and the bearing outer ring 62 is arranged inside the chuck seat 10. The upper end surface of the base plate 4 is provided with an annular groove 42 for placing the gear ring 61.

[0056] Here, by fixing the outer ring 62 of the bearing above the middle plate 6 and setting the annular groove 42 on the upper surface of the chassis 4, the middle plate 6 can rotate more stably around the rotating support plate 5.

[0057] Then, to ensure that the middle plate 6 does not wobble during rotation, please refer to... Figure 7As can be seen, in this embodiment, at least one stabilizing block 43 is provided on the periphery of the chassis 4, and a slot is provided on the edge of the middle plate 6 for one end of the stabilizing block 43 to extend into.

[0058] More specifically, a washer 7 and an oil pan 8 are provided between the slewing support plate 5 and the upper plate 9, with the oil pan 8 arranged around the washer 7.

[0059] The above description of the central rotating drive mechanism of a hardware processing machine is only a preferred embodiment of this utility model and does not limit the patent scope of this utility model. All equivalent structural transformations made under the inventive concept of this utility model using the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
