Description

TECHNICAL FIELD

[0001] The present application relates to the field of electric spark machining, and particularly relates to a rotating frame for electric spark machining of parts. BACKGROUND

[0002] Electric spark machining of parts is a technology for machining electrically conductive materials by using the principle of electric spark discharge. Electric spark machining is to remove electrically conductive materials by using the electric erosion effect generated in the pulse discharge between two electrodes immersed in working liquid. During machining, the tool electrode and the workpiece are connected to two poles of a pulse power source, and electric spark oil is filled into the discharge gap. When the gap between the two electrodes reaches a certain distance, the pulse voltage will break through the electric spark oil to generate spark discharge. A large amount of heat energy is instantaneously concentrated in the fine channel of the discharge, and the temperature can be as high as more than 10,000 degrees Celsius, and the pressure also changes sharply. The local small amount of metal material on the surface of the workpiece is immediately melted and vaporized, and splashes into the working liquid, rapidly condenses to form solid metal particles, and is taken away by the electric spark oil. The workpiece surface is left with a small pit. The shape and size of the workpiece electrode are copied on the workpiece by the feed motion of the tool electrode relative to the workpiece, including electric spark cavity machining and perforation machining, and are mainly used for machining cavities and various holes of molds.

[0003] However, when some workpieces need to be machined on both sides, the workpieces need to be turned over. Since the working liquid contains a large amount of harmful substances, the working liquid needs to be discharged before the workpieces are turned over by using a clamp. Therefore, the position after turning over is easy to change, and the turning over process is troublesome. SUMMARY

[0004] In view of the existing problems, the present application provides a rotating frame for electric spark machining of parts. The device can effectively solve the problems in the background art.

[0005] To solve the above problems, the present application adopts the following technical solutions: A rotating frame for electric spark machining of parts, comprising a machining device main body, a working liquid machining bin is arranged above the machining device main body, a rotating mechanism is installed on the upper surface of the machining device main body on both sides of the working liquid machining bin, the rotating mechanism comprises a distance adjusting slide rail, a rotating support frame, a rotating motor is connected between one end of the distance adjusting slide rail and the rotating support frame, a clamping mechanism is arranged below the distance adjusting slide rail, the clamping mechanism comprises a U-shaped clamping frame, a sliding vertical rod, and a swing support, an angle adjusting gear is installed between the U-shaped clamping frame and the swing support by using a movable shaft, a V-shaped protective cover plate is arranged on the outer side of the angle adjusting gear, an outer transmission gear is installed on the outer side of the upper end of the V-shaped protective cover plate, meshing gears are symmetrically arranged below the outer transmission gear, a gear transmission chain is arranged between the meshing gears and the angle adjusting gear inside the V-shaped protective cover plate on one side of the meshing gears, and a driving motor is installed on the outer side end of the outer transmission gear.

[0006] As a further scheme of the present application: the upper end of the sliding vertical rod is internally provided with a moving slider in the distance-adjusting slide rail, and the two groups of U-shaped clamping frames are internally provided with a workpiece to be machined in the working liquid processing chamber.

[0007] As a further scheme of the present application: a processing support base is arranged below the workpiece to be machined, and a support vertical rod is arranged on the upper surface of the processing support base, and guide rods are arranged on both sides of the support vertical rod.

[0008] As a further scheme of the present application: a lifting guide rail is arranged on the inner side of the working liquid processing chamber, a lifting screw rod is arranged inside the lifting guide rail and penetrates the guide rods, and a lifting motor is arranged on the upper end of the lifting screw rod.

[0009] As a further scheme of the present application: the inner diameter size of the U-shaped clamping frame is greater than the height size of the workpiece to be machined, a transmission gear is fixedly connected to the position corresponding to the meshing gear inside the V-shaped protective cover plate, and the transmission gear and the angle adjusting gear are engaged and clamped through the gear transmission chain.

[0010] As a further scheme of the present application: the outer transmission gear is engaged and clamped with the meshing gear, and a transmission shaft is connected between the driving motor and the outer transmission gear.

[0011] As a further scheme of the present application: a rotating shaft is connected between the distance-adjusting slide rail and the rotating motor, and the rotating support frame is fixedly connected with the processing device main body.

[0012] As a further scheme of the present application: the moving slider is slidingly connected with the distance-adjusting slide rail.

[0013] As a further scheme of the present application: the support vertical rod is fixedly connected with the processing support base.

[0014] As a further scheme of the present application: the guide rods are movably connected with the lifting screw rods, and the guide rods are slidingly connected with the lifting guide rail.

[0015] Compared with the prior art, the present application has the following advantages: 1. The drive motor drives the external transmission gear to rotate, which in turn meshes with the two meshing gears below. These meshing gears then synchronously drive the transmission gear inside the V-shaped protective cover to rotate. The V-shaped protective cover meshes with the gear transmission chain, thereby driving the gear transmission chain to adjust the angle of the gear. After the U-shaped clamping frame clamps and limits the workpiece on both sides, the rotary motor drives the adjustable slide rail to rotate on the outside of the rotary support frame, ensuring the overall flipping of the workpiece.

[0016] 2. By setting the internal dimensions of the U-shaped clamp to be larger than the thickness of the workpiece to be processed, the U-shaped clamp is set to control the rotation of the two U-shaped clamps to different angles. Therefore, it can handle the limiting of workpieces of different thicknesses. At the same time, the limiting method adopts the clamping limiting method rather than the clamping limiting method, thus preventing wear when workpieces with high surface requirements are clamped.

[0017] 3. After the support rod on the upper surface of the control support base contacts the lower surface of the workpiece to be processed, the drive motor is used to rotate in the opposite direction. Then, the external transmission gear, meshing gear drive gear transmission chain controls the angle adjustment gear to rotate. After the U-shaped clamp is rotated as a whole until the upper and lower sides do not contact the workpiece to be processed, the workpiece can be flipped over for further processing.

[0018] 4. The lifting motor drives the lifting screw to rotate, which in turn moves the guide rod on the outside of the processing support base downward as a whole. This allows for overall control of the installation position of the processing support base inside the processing chamber, thus facilitating the complete immersion of workpieces of different thicknesses into the working fluid inside the processing chamber.

[0019] 5. The support rods on the processing support base provide suspended support for the workpiece. Combined with the clamping mechanism, rotating mechanism, and lifting motor driving the processing support base to move up and down, the workpiece can be flipped without draining the working fluid. This also prevents the working fluid from splashing out when the flipped workpiece is immersed in the working fluid. Attached Figure Description
