Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to a turning device for machining. Background Technology

[0002] Machining refers to the process of changing the shape, size, or properties of a workpiece using a mechanical device. It can be divided into cutting and pressure processing according to the difference in processing methods. Some mechanical parts need to be processed on both sides during the production process, which requires a flipping device to flip the mechanical parts.

[0003] A search revealed Chinese Patent Publication No. CN219525370U, which discloses a workpiece flipping device for machining. The device includes two symmetrically arranged sliding devices for stable lateral movement. The top of the sliding devices is equipped with a rotating device for lifting and rotating the workpiece by a certain angle. The two rotating devices are equipped with clamping devices on their opposite sides for stably clamping workpieces of different specifications from four directions.

[0004] During the flipping process, the debris generated on the workpiece surface may gradually fall onto the worktable as the workpiece tilts. Some debris continues to adhere to the workpiece surface, resulting in a certain amount of debris between the workpiece and the worktable when the workpiece is flipped and placed on the worktable again. This affects the stability of the workpiece and may even cause crushing damage to the workpiece surface. Utility Model Content

[0005] The purpose of this invention is to provide a turning device for machining in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

The turning mechanism also includes a power assembly and a lifting assembly. The power assembly drives the two mounting plates to move. A striking mechanism is provided on the rotating shaft, comprising a turntable fixedly connected to the rotating shaft. Several circumferentially arranged protrusions are fixedly connected to the side of the turntable that is close to the mounting plate. A sliding rod is slidably connected inside the mounting plate. One end of the sliding rod extends out of the mounting plate and is fixedly connected to a striking hammer. The other end of the sliding rod extends out of the mounting plate and is fixedly connected to a limit plate. A spring is fixedly connected between the limit plate and the mounting plate. A collecting assembly is provided on the worktable for collecting the shaken-off debris.

[0008] Preferably, the collection component includes a screen plate, a material drop hole is provided on the top of the workbench, the screen plate is fixedly connected in the material drop hole, and a collection box is placed on the ground below the screen plate.

[0009] Preferably, both the protrusion and the end face of the hammer are arc-shaped.

[0010] Preferably, the flipping mechanism further includes a flipping motor, which is fixedly connected to the side wall of one of the mounting plates, and the output end of the flipping motor is connected to one of the rotating shafts via a coupling.

[0011] Preferably, the clamping assembly includes a clamping plate slidably connected to one side of two horizontal plates that are close to each other. The clamping plates are symmetrically arranged front and back. A rubber pad is fixedly connected to one side of the two clamping plates that are close to each other.

The two clamping plates 205 are driven by the parallel hydraulic cylinder to move synchronously in the direction of moving closer to each other or further away from each other. The parallel hydraulic cylinder is existing technology and will not be described in detail.

[0029] The flipping mechanism also includes a flipping motor 206, which is bolted to the side wall of one of the mounting plates 202. The output end of the flipping motor 206 is connected to one of the rotating shafts 203 via a coupling.

[0030] The flipping mechanism also includes a power assembly that drives two mounting plates 202 to move. The power assembly includes a rotary motor 301. The bottom of the worktable 1 has two sets of mounting slots arranged symmetrically front and back. The rotary motor 301 is fixedly connected in one of the mounting slots. The output end of the rotary motor 301 is connected to a double-acting lead screw 302 through a coupling. The double-acting lead screw 302 is rotatably connected in the mounting slot. A guide rod 303 is fixedly connected in the other mounting slot. A mounting frame 201 is slidably connected on the worktable 1. The mounting frame 201 is threadedly connected to the double-acting lead screw 302. The mounting frame 201 is slidably connected to the guide rod 303. The top of the mounting frame 201 extends out of the worktable 1 and is fixedly connected to the mounting plate 202.

[0031] The flipping mechanism also includes a lifting assembly, which includes an electric push rod 401 fixedly connected to the bottom of the worktable 1. A top plate 402 is fixedly connected to the top of the electric push rod 401. A placement slot is provided on the top of the worktable 1, and the top plate 402 is located in the placement slot.

[0032] A striking mechanism is provided on the rotating shaft 203. The striking mechanism includes a turntable 501 fixedly connected to the rotating shaft 203. Several circumferentially arranged protrusions 502 are fixedly connected to the side of the turntable 501 near the mounting plate 202. A slide rod 503 is slidably connected inside the mounting plate 202. One end of the slide rod 503 extends out of the mounting plate 202 and is fixedly connected to a striking hammer 504. The other end of the slide rod 503 extends out of the mounting plate 202 and is fixedly connected to a limiting plate 505. A spring 506 is fixedly connected between the limiting plate 505 and the mounting plate 202. The end faces of the protrusions 502 and the striking hammer 504 are both arc-shaped to improve the stability of the protrusions 502 and the striking hammer 504 when they move relative to each other and to avoid jamming.

[0033] The workbench 1 is equipped with a collection component for collecting the shaken debris. The collection component includes a screen plate 507. The top of the workbench 1 has a discharge hole, and the screen plate 507 is fixedly connected in the discharge hole. A collection box 508 is placed on the ground below the screen plate 507.

[0034] Working principle: When it is necessary to flip the workpiece on the worktable 1, firstly, the electric push rod 401 is controlled to lift the top plate 402 to the set height, and the rotary motor 301 is started. The rotary motor 301 drives the double-acting screw 302 to rotate, and the double-acting screw 302 drives the two mounting brackets 201 to move towards each other. After the horizontal plate 204 abuts against the workpiece, the mounting brackets 201 stop moving. The parallel hydraulic cylinder is controlled to move the two clamping plates 205 towards each other to clamp the workpiece. Then, the electric push rod 401 lowers the top plate 402 to a suitable height, and the flipping motor 206 is started. The flipping motor 206 drives the rotating shaft 203 to rotate the horizontal plate 204, flipping the workpiece clamped on the horizontal plate 204. During the flipping process, the turntable 501 rotates with the rotation of the rotating shaft 203. When the turntable 501 rotates, the workpiece is flipped. When the protrusion 502 on the worktable 1 comes into contact with the hammer 504, the protrusion 502 drives the hammer 504 to move away from the turntable 501. After the protrusion 502 moves away, the hammer 504 moves quickly towards the turntable 501 under the action of the spring 506, striking the turntable 501 and causing the workpiece to vibrate, which helps to shake off the debris on the workpiece. The debris falls into the collection box 508 through the mesh plate 507, preventing the debris from affecting the stability of the workpiece. After the workpiece is flipped, the top plate 402 is raised to a suitable height by the electric push rod 401, and the workpiece is lifted by the top plate 402. Then, the clamping plate 205 releases the workpiece, and the rotary motor 301 is started. The rotary motor 301 drives the two mounting brackets 201 away, so that the horizontal plate 204 is separated from the side of the workpiece. The top plate 402 drives the workpiece to fall down and put the workpiece back on the worktable 1.
