Description

Technical Field

[0001] The utility model relates to a feeding device for punching sheet processing, belonging to the technical field of motor manufacturing equipment. Background Art

[0002] The motor core is divided into a stator core and a rotor core, which are respectively formed by stacking stator punching sheets and rotor punching sheets. During the processing of the stator punching sheets and the rotor punching sheets, the blanks must first be punched out on the metal strip, and then the blanks are punched out for a second time to process structures such as tooth grooves. In order to improve production efficiency, the punching blanks are automatically transported to the punching machine. There are now sheet feeding machines for punching sheets and slots on the market. Most of them adopt a rotating magnetic feeding mechanism, that is, a round sheet material with a center hole is placed on a support frame, and a sheet of material is sent to the punching position through a rotating magnetic suction cup. In order to achieve continuous feeding without stopping the machine, there is an automatic feeding device for punching sheet processing such as the one disclosed in announcement number CN212944907U. However, on the one hand, it is difficult for the lifting mechanism and the bracket to automatically and accurately match each other in this device. On the other hand, since the weight of the bracket after stacking the punching sheets is very large, the lifting mechanism is connected to one side of the bracket through the support part. Due to uneven force, the lifting mechanism and the connection between the lifting mechanism and the bracket are subject to a large deviation force, resulting in poor stability of the connection and affecting the service life of the lifting mechanism. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a feeding device for punching sheet processing, wherein the lifting mechanism and the bracket for stacking the punching sheets can be accurately and stably connected, thereby solving the shortcomings of the prior art.

[0004] The technical solution of the utility model is: a feeding device for punching sheet processing, comprising a support seat, a support plate is connected to the support seat, a plurality of circumferentially arranged bracket assemblies for stacking punching sheets are arranged on the support plate, a lifting mechanism is arranged in the support seat, a matching positioning mechanism is arranged between the support seat and the support plate, when the support plate rotates relative to the support seat, the support plate is stopped at a limited position through the cooperation of the positioning mechanism, the lifting mechanism comprises a lifting platform, a plurality of circumferentially arranged pillars are arranged on the lifting platform, a limiting hole coaxially distributed with the bracket assembly is arranged on the support plate, when the support plate is at the limited position, the pillar is aligned with the limiting hole, and when the lifting platform rises, the pillar passes through the limiting hole to push the punching sheet on the bracket assembly to rise.

[0005] The positioning mechanism further comprises a ball screw and a positioning hole which are arranged on the support seat and match the bottom of the support plate.

[0006] Furthermore, rolling elements are distributed on the support seat, and the rolling elements are rollingly connected to the support plate.

[0007] Furthermore, the support plate is provided with a positioning mechanism that cooperates with the bracket assembly. The positioning mechanism contacts the bracket assembly in multiple directions, so that the bracket assembly can be placed in a fixed position on the support plate.

[0008] The bracket assembly further comprises a bracket and a tray, wherein the tray is used to carry punching sheets, the bracket is in an inverted T shape, the tray slides on the bracket and cooperates with the bottom of the bracket, and the support of the lifting platform cooperates with the bottom of the tray.

[0009] By implementing the utility model, when the support plate rotates relative to the support seat, the support plate is stopped at a limited position through the cooperation of the positioning mechanism. When at the limited position, a number of pillars on the lifting mechanism are coaxially distributed up and down with one of the bracket assemblies. When the lifting platform rises, the pillars pass through the limiting holes on the support plate to push the punching piece on the bracket assembly to rise, thereby conveniently realizing the connection and cooperation between the lifting mechanism and the bracket assembly. When the lifting mechanism drives the punching piece to rise, the force is stably applied, and the stability is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Embodiments of the present utility model: Figures 1 to 3 As shown, a feeding device for punching sheet processing, which delivers the punching sheet to the punching position of the punching machine 6 through a rotating magnetic suction cup 4, includes a support seat 1, a support plate 2 is connected to the support seat 1, and bracket assemblies 3 for stacking the punching sheets are symmetrically provided on both sides of the support plate 2. A lifting mechanism is provided in the support seat 1, and the lifting mechanism may include a motor 5, a screw assembly and a lifting platform provided with a pillar 7. The motor drives the screw assembly to rotate to drive the lifting platform provided with the pillar 7 to rise and fall. A matching positioning mechanism is provided between the support seat 1 and the support plate 2, and the positioning mechanism includes a ball screw 8 provided on the support seat 1 and a positioning hole provided on the support plate 2. When the support plate 2 rotates on the support seat 1 until the ball screw 8 matches the positioning hole, the support plate 2 stops at a limited position, and the pillars 7 are arranged on the lifting platform along the circumference.

[0015] The support plate 2 is provided with corresponding limiting holes. When the support plate 2 is in the limited position, the limiting holes on the support plate 2 are aligned with the pillars 7 and are on the same axis as the screw assembly and the bracket assembly 3. When the lifting platform rises, the pillars 7 pass through the limiting holes to push the punching pieces on the bracket assembly 3 to rise. The ball screws 8 cooperate with the positioning holes to limit the position, which facilitates the rotation and positioning of the support plate 2 and conveniently realizes the connection and cooperation between the lifting mechanism and the bracket assembly 3. The limiting holes on the support plate 2 are aligned with the pillars 7 and are on the same axis as the screw assembly and the bracket assembly 3. When the lifting mechanism drives the punching pieces to rise, the force is stably applied, and the lifting mechanism has better stability. Moreover, since the pillars 7 pass through the limiting holes to further limit the support plate 2, the support plate 2 will not rotate during the pushing process of the punching pieces.

[0016] As a preferred embodiment, rolling elements are distributed on the support seat 1. The rolling elements are balls 9 spherically connected to the support seat 1. The balls 9 provide rolling support for the support plate 2. During use, one side of the bracket assemblies 3 on both sides of the support plate 2 will be full of punching sheets, while the other side will be empty. Due to uneven force, the support plate 2 is prone to tilt. By arranging the balls 9 to support it, the stability and balance of the support plate 2 are guaranteed, and the rotation of the support plate 2 is not affected.

[0017] As a preferred embodiment, the support plate 2 is provided with a groove 13 that matches with the bracket assembly 3. The bracket assembly 3 is limited by placing the bottom in the groove 13 so that the bracket assembly 3 is placed at a fixed position on the support plate 2. The bracket assembly 3 has a lifting hole 10. A lifting device can be set on or beside the support seat 1. The bracket assembly 3 with stacked punches can be placed beside the support seat 1 and lifted to the support plate 2 by the lifting device to match with the groove 13. The bracket assembly 3 can be prepared with multiple punches pre-stacked and ready for use. The punches are stacked at a lower position to reduce labor intensity. The bracket assembly 3 includes a bracket 11 and a tray. 12. The tray 12 is used to carry the punching sheet. The bracket 11 is in an inverted T shape. The tray 12 slides on the bracket 11 and cooperates with the bottom of the bracket 11. The tray 12 is plugged into the groove 13. The center of the groove 13 has a positioning protrusion 14. The bottom of the bracket 11 has a matching positioning hole 1. When the bracket assembly 3 cooperates with the groove 13, the tray 12 is plugged into the groove 13, and the bracket 11 is plugged into the positioning protrusion 14 through the positioning hole 1. The limiting hole for the support 7 to pass through is set in the groove 13. When the lifting platform rises, the support 7 passes through the limiting hole to lift the tray 12 carrying the punching sheet upward so that the magnetic suction cup 4 can deliver the punching sheet to the punching position of the punch press 6.
