Description

Technical Field

[0001] This utility model specifically relates to the technical field of grooving machines, and specifically to a fully servo high-speed grooving machine with a tangential straight inclined groove stamping structure. Background Technology

[0002] A grooving machine is a specialized mechanical device mainly used to punch holes or cut specific groove shapes on the surface of materials such as metal and plastic. CNC grooving machines are often used to process the holes and grooves on the silicon steel sheets of the stator and rotor in motors. In some motors, after the silicon steel sheets of the stator and rotor are stacked, the internal holes and grooves need to be stacked obliquely, and the holes and grooves need to be tilted at a certain angle or helical angle along the motor axis so that the center line of the groove is no longer parallel to the motor axis. Therefore, an oblique groove punching structure is required in the processing. Referring to the announcement number "CN201120349272.4", the disclosed "A CNC Grooving Machine Tool Oblique Grooving Power Device" includes: a servo motor and a mounting sleeve. The output shaft of the servo motor is connected to a coupling, and the other end of the coupling is connected to a ball screw. The ball screw is screwed with a screw nut, and a connecting key that is slidably fitted inside the mounting sleeve is fixedly connected to the screw nut. The connecting key is connected to the punching die through a hook plate.

[0003] The existing slant punch structure requires the worktable plate used to fix the mold to be moved laterally during processing. Therefore, a power mechanism needs to be installed at the bottom of the worktable plate, and a movable mechanism needs to be added between the worktable plate and the bed to facilitate sliding. This increases the overall thickness of the worktable plate and reduces the distance between the worktable plate and the punch, which affects the mold adjustment and the robot's handling of silicon steel sheets. Therefore, it has drawbacks in use. Utility Model Content

[0004] The purpose of this invention is to provide a fully servo high-speed grooving machine with a tangential straight groove punching structure, in order to solve the problem mentioned in the background art that the currently used groove punching structure leads to an increase in the overall thickness of the worktable, reduces the distance between the worktable and the punch, and affects the mold adjustment and the robot's handling of silicon steel sheets, thus having drawbacks in use.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fully servo high-speed grooving machine with a tangential straight groove stamping structure includes a punch press base plate, an indexing seat, and a pressing seat.

[0017] 1. This utility model includes an indexing seat, a first servo motor, and a ball screw. The indexing seat and the punch press base plate are slidably connected by a slider pressure bar and long and short guide rails. During processing, the first servo motor drives the ball screw to rotate, which, together with the nut seat, drives the entire indexing seat to move left and right.

The ball screw 14 is threaded; two sets of sliding pressure bars 22 are symmetrically distributed at the bottom of the indexing seat 3; the nut seat 21, the ball screw 14, and the indexing seat 3 form a sliding structure; a worktable 4 is installed in the middle of one end of the punch press bed 2 near the indexing seat 3, and a punch 11 is installed at one end of the punch press bed 2, with the punch 11 positioned directly above the worktable 4; a support frame 5 is installed on one side of the indexing seat 3, and an adjusting cylinder 6 is installed on the support frame 5; the extended end of the adjusting cylinder 6 is connected to the slide 7, and the slide 7 is slidably connected to the support frame 5; the pressure plate seat 8 is installed at the bottom of the slide 7.

[0031] More specifically, the ball screw 14 is driven to rotate by the first servo motor 13.

[0032] As a further explanation of this embodiment, the ball screw 14 rotates while simultaneously driving the nut seat 21 and the indexing seat 3 to move synchronously.

[0033] In this embodiment, an intermediate shaft seat 17 is installed inside the indexing seat 3, and a second servo motor 18 is installed on the top of the intermediate shaft seat 17; the output shaft of the second servo motor 18 is connected to a gear set 19, and the gear set 19 is connected to an indexing shaft 20; the indexing shaft 20 is installed inside the indexing seat 3 near the end of the punch press bed 2, and the top of the indexing shaft 20 penetrates through the top of the indexing seat 3.

[0034] More specifically, the indexing shaft 20 is driven to rotate by the second servo motor 18 in conjunction with the gear set 19.

[0035] As a further explanation of this embodiment, before processing, a centering head corresponding to the silicon steel sheet needs to be installed on the top of the indexing shaft 20 to fix the silicon steel sheet. During processing, the silicon steel sheet and the centering head rotate synchronously with the indexing shaft 20.

[0036] In this embodiment, a spherical bearing 10 is installed inside the tablet press 8, and a tablet press 9 is installed at the bottom of the spherical bearing 10.

[0037] More specifically, the spherical bearing 10 allows the axis of the tableting disc 9 to tilt within a certain range.

[0038] As a further explanation of this embodiment, the tablet pressing disc 9 can automatically compensate for the misalignment error between the shaft and the bearing seat, reducing the additional stress and wear caused by misalignment.

[0039] In this embodiment, the tablet pressing disc 9, tablet pressing seat 8, slide 7 and adjusting cylinder 6 form a lifting structure, and the tablet pressing disc 9 is connected to the spherical bearing 10 by rotation.

[0040] More specifically, the slide 7, tablet press 8, and tablet press 9 are moved vertically by adjusting the cylinder 6.

[0041] As a further explanation of this embodiment, the tablet pressing disc 9 rotates synchronously with the silicon steel sheet during processing.

[0042] In this embodiment, the centerline of the tablet pressing disc 9 and the centerline of the indexing shaft 20 are on the same vertical straight line, and the indexing shaft 20 and the indexing seat 3 are connected by a rotatable connection.

[0043] More specifically, during processing, the silicon steel sheet is clamped by the centering head installed on the top of the indexing shaft 20 in conjunction with the pressing plate 9.

[0044] As a further illustration of this embodiment, during processing, the tableting disc 9 is always kept directly above the indexing axis 20.

[0045] In this embodiment, each set of slider pressure strips 22 is provided in two symmetrical arrangements, and one set of slider pressure strips 22 is slidably connected to the long guide rail 15, while the other set of slider pressure strips 22 is slidably connected to the two short guide rails 16.

[0046] More specifically, the movement trajectory of the indexing seat 3 is restricted by the slider pressure bar 22 in conjunction with the long guide rail 15 and the short guide rail 16.

[0047] As a further explanation of this embodiment, when the ball screw 14 rotates, it works in conjunction with the nut seat 21 to drive the indexing seat 3 to move as a whole.

[0048] The working principle of this utility model is as follows: When in use, the centering head corresponding to the empty space of the silicon steel sheet is first installed on the top of the indexing shaft 20, and the fixing plate for supporting the silicon steel sheet is installed on the top of the indexing seat 3. The corresponding punching mold is installed on the top of the worktable 4 and the bottom of the punch 11 respectively.

[0049] During processing, the silicon steel sheet to be processed is placed on the centering head at the top of the indexing shaft 20 by the loading and unloading robot. Then, the external power is turned on, the adjusting cylinder 6 is started, and the slide 7 is pushed down as a whole, which in turn drives the pressing seat 8 and the pressing plate 9 to move down synchronously. The pressing plate 9 presses the silicon steel sheet tightly on the centering head to ensure that the silicon steel sheet is kept horizontal. Then, the punch 11 is started to perform stamping processing on the silicon steel sheet. Simultaneously, the second servo motor 18 is started, which works with the gear set 19 to drive the indexing shaft 20 to rotate, which in turn drives the silicon steel sheet to rotate synchronously, so that the holes and slots are distributed in a ring on the silicon steel sheet.

[0050] When it is necessary to adjust the position of the slots on the silicon steel sheet, the first servo motor 13 is started, which drives the ball screw 14 to rotate, thereby driving the indexing seat 3 to move horizontally as a whole, and simultaneously driving the silicon steel sheet mounted on the top to move horizontally. During this process, the indexing seat 3 drives the support frame 5 to move horizontally, and the pressing plate 9 always keeps the silicon steel sheet clamped.
