Description

Technical Field

[0001] The invention belongs to the technical field of boring and honing combined machine tools, in particular to a boring and honing combined machine tool. Background Art

[0002] For the inner hole processing of the coil housing for automotive electrical control, a boring and honing combination machine tool is usually used. The boring mechanism and honing mechanism on the machine tool are combined to perform boring and honing operations after the workpiece is placed on a placement rack.

[0003] In the prior art, the boring and honing combination machine tool usually places a cylindrical workpiece with an inner hole on the top on a placement rack during use, and after placement, the workpiece to be processed is clamped and fixed by a positioning and clamping assembly, and after fixation, the boring mechanism and the honing mechanism above are coordinated in sequence by a rotating mechanism to complete the processing of the inner hole of the coil housing. However, in actual use, since the surface of the cylindrical workpiece is an arc, multi-point contact clamping is actually used for clamping and fixing. Although multi-point extrusion clamping can achieve clamping and fixing of the cylindrical workpiece, the contact area is small, and the actual pressure after fixing is too large, which exerts a large force on the workpiece under rotation processing. On the one hand, the large pressure makes it easy to damage the extrusion and fixing of the workpiece. At the same time, when the workpiece is subjected to force and has a tendency to rotate, the actual fixing stability is poor, and the workpiece is prone to rotation slippage, which affects the quality of the actual boring and honing processing and has poor use effect.

[0004] In addition, the boring and honing combination machine tools in the prior art have obvious cutting and friction on the workpiece during the actual boring and honing processes, and the actual temperature is high. It is usually necessary to continuously spray the cutting fluid to flush away the chips and abrasive particles, improve the surface roughness and reduce the temperature of the cutting area. However, during the continuous spraying and flushing process, the cutting fluid mixed with the abrasive particles flows out everywhere, making the working area of ​​the machine tool dirty. The actual centralized collection and recovery of the cutting fluid and abrasive particles is not effective, the subsequent cleaning operation is troublesome, and the use effect is not good.

When the internal oil pressure increases, the oil pressure thrust pushes the movable plate 19 to move. As the spring 33 stretches, the movable plate 19 drives the push plate 17 to slide along the fixed frame 16, so that the inner end surface of the push plate 17 The clamping plate 18 contacts and presses the surface of the workpiece to complete the surface contact clamping and fixing. After the clamping is completed, the motor 9 drives the worktable 8 to rotate a fixed angle, and then the boring mechanism 3 moves downward and performs the boring operation.

While completing the clamping and fixing, the actual contact area is greatly increased. When the workpiece is subjected to rotational force processing, the actual clamping stability is greatly improved to avoid slipping. Moreover, under the large-area contact effect, the pressure under the same clamping pressure is reduced, and the pressure damage to the workpiece surface is reduced. The actual workpiece boring and honing process is stable and reliable, the workpiece surface protection effect is good, and it is easy to use.

[0034] In addition, by utilizing three groups of push plates 17 corresponding to a group of arc-shaped clamping plates 18, under the hydraulic thrust of the hydraulic oil, for workpieces of different diameters, when the clamping plates 18 are pushed and brought into contact with the surface of the workpiece, the metal clamping plates 18 made of elastic material and the three groups of push plates 17 distributed on the sides can obtain sufficient hydraulic thrust under the hydraulic thrust, and the elastic metal clamping plates 18 can adapt well to the surfaces of workpieces of different diameters and achieve good contact.

[0038] During use, the workbench 8 is ensured to have a stable rotation effect by utilizing the movable socket of the annular groove 25 and the fixed ring 26. A collection space is formed between the collecting ring 27 and the fixed seat 7, and the collection is completed in cooperation with the internal filtering mechanism 29. The cutting fluid flows out through the filter hole 293, wherein the notch 28 is adapted to the loading of the workpiece, and the operating port 30 ensures that the filter ring 292 is easy to grab and remove, so as to facilitate cleaning and collection. During the smooth upward movement and removal process, the abrasive particles on the top of the collection are removed, wherein a groove can be provided on the top surface of the filter ring 292 to improve the collection and storage effect.

[0039] Second embodiment: When the workpiece is being bored and honed, as the spray mechanism 5 continuously sprays the cutting fluid out of the workpiece processing area, the abrasive particles generated by the processing flow together with the flushed cutting fluid, and gradually flow toward the fixed seat 7 during the rotation of the worktable 8.
