Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, and in particular to a servo-driven automatic double-head chamfering machine for iron cores. Background Technology

[0002] During the production of toroidal iron cores, the outer wall edges and inner hole edges of the toroidal iron core need to be chamfered to avoid scratching the winding. The early method was to manually place the iron core in the corresponding position and then press down with a chamfering drill bit to chamfer it. This was a semi-automated method with low production efficiency, and workers were prone to injury from touching the chamfering drill bit, which was unsafe.

[0003] Existing chamfering equipment typically requires manual clamping (removal) of the iron core, making automated clamping impossible and impacting processing efficiency. The few iron core chamfering machines with automated feeding systems are prone to interference with fixture operation during feeding and unloading, resulting in a high failure rate. Utility Model Content

[0004] The purpose of this utility model is to provide a servo-driven automatic double-head chamfering machine for iron cores. Its structure is simple and reasonable, and it automatically feeds and picks up materials without interfering with the fixtures, thus avoiding the risk of worker injury. It can chamfer iron cores with high efficiency and can chamfer both sides at the same time.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A servo-driven automatic double-head chamfering machine for iron cores includes a frame, a feeding assembly, a receiving assembly, tooling fixtures, a chamfering processing assembly, and a material transfer mechanical claw assembly;

[0007] The frame is vertically arranged, and a horizontally arranged worktable is provided on it;

[0008] The tooling fixture is arranged longitudinally, and chamfering processing components are provided horizontally on its left and right sides; the chamfering processing components are located on the worktable surface;

[0009] The tooling fixture is equipped with a feeding assembly and a receiving assembly on its front and rear sides, respectively; a material transfer mechanical claw assembly is provided on the top of the tooling fixture.

[0010] The material transfer mechanical claw assembly picks up and transfers the iron core to be processed from the feeding assembly, places the iron core into the tooling fixture, and the tooling fixture clamps and fixes the iron core; the chamfering processing assemblies on the left and right sides perform chamfering processing on the iron core, successively performing chamfering processing on the outer wall edge and the inner hole edge; after processing, the material transfer mechanical claw assembly picks up and transfers the iron core to the receiving assembly.

[0011] The material handling mechanical gripper assembly includes a top frame, a slide block, slide rails, a forward / reverse cylinder, a lifting cylinder, and pneumatic grippers (pneumatic grippers, pneumatic fingers, pneumatic cylinders). The top frame is horizontally mounted on a worktable and has two horizontally and parallel slide rails. A slider is fixed to the bottom of the slide block and fits onto the slide rails. The forward / reverse cylinder housing is horizontally fixed to the slide block, and its output shaft is connected to the top frame. The forward / reverse cylinder drives the slide block to move back and forth along the slide rails. The lifting cylinder is vertically mounted on the slide block, and its output shaft is connected to the gripper mounting base. The grippers are vertically mounted on the gripper mounting base; preferably, there are two grippers, arranged one in front of the other. The grippers are used to hold the iron core.

[0012] The tooling fixture includes an opening and closing motor, rotating gears, racks, clamping seats, and grippers. The opening and closing motor is vertically positioned, with rotating gears mounted on its output shaft. Racks are located on the left and right sides of the rotating gears, meshing with the racks for transmission. Clamping seats are fixed on the racks, and grippers are mounted on the clamping seats. The grippers have semi-circular cavities on their inner sides, and the two grippers are positioned opposite each other to clamp the circular outer wall of the rod-shaped iron core. When the opening and closing motor rotates, the two racks move towards or away from each other, causing the two grippers to move closer to or away from the iron core, thus releasing the iron core. Since the pneumatic grippers clamp the iron core from the left and right sides, while the grippers clamp the iron core from the front and back, they do not interfere with each other. Specifically, during loading, the pneumatic grippers clamp the left and right end faces of the iron core, suspending the iron core at the desired position. Then, the grippers tighten, clamping the arc-shaped outer wall of the iron core from both the front and back sides. The pneumatic grippers then release the iron core and rise back to their original position.

[0013] The receiving assembly includes a receiving cylinder, a pushing cylinder, a V-shaped limiting seat, and a receiving V-groove. The receiving cylinder is vertically positioned and connected to the V-shaped limiting seat. The upper surface of the V-shaped limiting seat has a V-shaped groove to restrict the rolling of the iron core. A baffle is located on the right side of the V-shaped limiting seat, and a horizontally positioned pushing cylinder is located on the left side. The output shaft of the pushing cylinder is connected to a push plate. The receiving V-groove is horizontally positioned on the frame to the right of the V-shaped limiting seat.

[0014] After processing, the iron cores are gripped and transferred to the receiving assembly by the material handling mechanism. The receiving cylinder rises, and the V-shaped limiting seat rises to receive the iron cores. The iron cores are placed in the V-shaped limiting seat to restrict their rolling displacement. The pushing cylinder pushes the output shaft, causing the push plate to move to the right, pushing the iron cores against the baffle for neat arrangement and stacking. After the V-shaped limiting seat is full, the worker places the iron cores into the receiving V-groove on the right side.

[0015] The chamfering assembly includes a motor, a rotating shaft, a turntable, and a cutting tool. The motor is horizontally positioned and connected to the rotating shaft via a synchronous belt and two synchronous pulleys, driving the shaft to rotate. The end face of the rotating shaft is connected to a vertically positioned turntable, on which the cutting tool is mounted. The rotating shaft can move laterally. A key is provided on the inner wall of the synchronous pulleys, and a keyway is provided on the outer wall of the rotating shaft. The rotating shaft passes through the inner wall of the synchronous pulleys, and the key is located within the keyway. The rotation of the synchronous belt drives the rotating shaft to rotate. The rotating shaft can move laterally (along its axial direction), achieving "tool feed" and "tool retraction." The rotating shaft is connected to a power unit, which propels its lateral movement; this is existing technology and will not be elaborated upon here.

[0016] The beneficial effects of this utility model are:

[0017] Its structural design is simple and reasonable, with automatic feeding and unloading, and no interference with the fixture, avoiding the risk of worker injury; the iron core chamfering process is highly efficient and can be chamfered on both sides at the same time.

[0030] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] like Figures 1-12 As shown, a servo-driven automatic double-head chamfering machine for iron cores includes a frame 1, a feeding assembly 2, a receiving assembly 3, a tooling fixture 4, a chamfering processing assembly 5, and a material transfer mechanical claw assembly 6.

[0032] The frame 1 is vertically arranged, and a horizontally arranged worktable 10 is provided on it;

[0033] The tooling fixture 4 is arranged longitudinally, and chamfering processing components 5 are arranged horizontally on its left and right sides; the chamfering processing components 5 are arranged on the worktable surface 10.

[0034] The tooling fixture 4 is provided with a feeding assembly 2 and a receiving assembly 3 on its front and rear sides respectively; a material transfer mechanical claw assembly 6 is provided on the top of the tooling fixture 4.

[0035] like Figure 10 , Figure 11 As shown, the material transfer mechanical claw assembly 6 clamps and transfers the iron core to be processed on the feeding assembly 2, and places the iron core on the tooling fixture 4. The tooling fixture 4 clamps and fixes the iron core 7. The chamfering processing assemblies 5 on the left and right sides perform chamfering processing on the iron core 7, and successively perform chamfering processing on the outer wall edge and the inner hole edge. After processing, the material transfer mechanical claw assembly 6 clamps and transfers the iron core 7 to the receiving assembly 3.

[0036] The material handling mechanical gripper assembly 6 includes a top frame 61, a slide block 62, a slide rail 63, a forward / reverse cylinder 64, a lifting cylinder 65, and pneumatic grippers 66 (pneumatic grippers, pneumatic fingers, pneumatic cylinders). The top frame 61 is horizontally mounted on the worktable 10, and has two horizontally and parallel slide rails 63 on it. A slider 67 is fixed to the bottom of the slide block 62, and the slider 67 is fitted onto the slide rails 63. The housing of the forward / reverse cylinder 64 is horizontally fixed to the slide block 62, and its output shaft is connected to the top frame 61. The forward / reverse cylinder 64 drives the slide block 62 to move back and forth along the slide rails 63. The lifting cylinder 65 is vertically mounted on the slide block 62, and its output shaft is connected to the gripper 66 mounting base. The grippers 66 are vertically mounted on the gripper 66 mounting base. Preferably, there are two grippers 66, arranged one in front of the other. The grippers 66 are used to clamp the iron core 7.

[0037] The tooling fixture 4 includes an opening / closing motor 41, a rotating gear 42, a rack 43, a clamping seat 44, and grippers 45. The opening / closing motor 41 is vertically arranged, with a rotating gear 42 sleeved on its output shaft. Racks 43 are respectively located on the left and right sides of the rotating gear 42, meshing with the racks 43 for transmission. A clamping seat 44 is fixedly mounted on each rack 43, and grippers 45 are mounted on each clamping seat 44. Each gripper 45 has a semi-circular cavity on its inner side, and the two grippers 45 are arranged opposite each other, clamping the circular outer wall of the rod-shaped iron core 7. When the opening / closing motor 41 rotates, the two racks 43 move towards or away from each other, causing the two grippers 45 to move closer to or away from the iron core 7, thus releasing the iron core 7. Since the pneumatic gripper 66 clamps the iron core 7 from the left and right, and the grippers 45 clamp the iron core 7 from the front and back, they do not interfere with each other. Specifically, during feeding, the pneumatic gripper 66 clamps the left and right end faces of the iron core 7, suspending the iron core 7 at the position to be installed. Then, the gripper 45 tightens, clamping the arc-shaped outer wall of the iron core 7 from both the front and rear sides. The pneumatic gripper 66 then releases the iron core 7 and rises to reset.

[0038] The receiving assembly 3 includes a receiving cylinder 31, a pushing cylinder 32, a V-shaped limiting seat 33, and a receiving V-groove 34. The receiving cylinder 31 is vertically arranged and connected to the V-shaped limiting seat 33. The upper surface of the V-shaped limiting seat 33 has a V-shaped groove to restrict the rolling of the iron core 7. A baffle is provided on the right side of the V-shaped limiting seat 33, and a horizontally arranged pushing cylinder 32 is provided on the left side. The output shaft of the pushing cylinder 32 is connected to a push plate. The receiving V-groove 34 is horizontally arranged on the frame 1 to the right of the V-shaped limiting seat 33.

[0039] After processing, the iron core 7 is clamped and transferred by the material transfer mechanical claw assembly 6 to the top of the receiving assembly 3. The receiving cylinder 31 rises, and the supporting V-shaped limit seat 33 rises to receive the iron core 7. The iron core 7 is placed in the V-shaped limit seat 33 to restrict its rolling displacement. The pushing cylinder 32 pushes the output shaft, causing the push plate to move to the right and push the iron core 7 against the baffle to be neatly arranged and stacked. After the V-shaped limit seat 33 is full, the worker places the iron core 7 into the receiving V-groove 34 on the right side.

[0040] The chamfering assembly 5 includes a motor 51, a rotating shaft 52, a turntable 53, and a cutting tool 54. The motor 51 is horizontally positioned and connected to the rotating shaft 52 via a synchronous belt and two synchronous pulleys, driving the rotating shaft 52 to rotate. The end face of the rotating shaft 52 is connected to the vertically positioned turntable 53, on which the cutting tool 54 is mounted. The rotating shaft 52 can move laterally. A key block 561 is provided on the inner wall of the synchronous pulley, and a keyway 521 is provided on the outer wall of the rotating shaft 52. The rotating shaft 52 passes through the inner wall of the synchronous pulley, and the key block 561 is located within the keyway 521. When the synchronous belt rotates, it drives the rotating shaft 52 to rotate. The rotating shaft 52 can move laterally (along its axial direction) to achieve "tool feed" and "tool retraction". The rotating shaft 52 is connected to a power unit to drive its lateral movement; this is prior art and will not be described in detail here.
