Description

Technical Field

[0001] The utility model belongs to the technical field of machining equipment, and particularly relates to a honing machine. Background Art

[0002] During the repair and remanufacturing process of hydraulic column jacks, for the local micro-defects or the design requirements of local surface finish generated in the production process of the stainless steel inlay process, it is necessary to polish the inner hole. When the hydraulic column jack is used for a long time or the flowing medium is not clean, stubborn dirt adheres to the surface of the inner hole. To meet the requirements for reuse, it is necessary to polish it. The honing machine is mainly used for machining cylindrical holes. This machining method is particularly suitable for machining the inner holes of the columns and cylinders of hydraulic supports. By optimizing the process parameters and designing specific tooling, the surface quality of the inner hole can be effectively improved. Since the honing head will be driven to rotate and at the same time perform a linear motion, how to effectively control its expansion and contraction is particularly important.

The rotating motor is connected to a rotating shaft through a reduction gearbox. One end of the rotating shaft away from the rotating motor is erected on the guiding bracket and connected to the honing head through a connecting head to drive the honing head to rotate. A guide rod is slidably connected in the rotating shaft. One end of the guide rod extends out of the rotating shaft and is connected to the power output end of the telescopic oil cylinder, and the other end extends out of the rotating shaft and is connected to the inside of the honing head, and controls the expansion and contraction of the honing head as the telescopic oil cylinder reciprocates.

[0027] The present utility model will be further described below with reference to the accompanying drawings.

[0028] Such as Figure 1As shown in the figure, the honing machine includes a frame 1. A slide rail 7, a guiding support 16 and an adjusting support 19 are successively connected to the frame 1. A traveling trolley 8 is slidably connected to the slide rail 7. A driving mechanism for driving the traveling trolley 8 to reciprocate on the slide rail 7 is provided on the frame 1. A liquid storage tank 20 is provided around the adjusting support 19 on the frame 1. A rotating motor 10 and a telescopic oil cylinder 9 are connected to the traveling trolley 8. The rotating motor 10 is connected to a rotating shaft 13 through a speed reducer 12. One end of the rotating shaft 13 away from the rotating motor 10 is mounted on the guiding support 16 and is connected to a honing head 18 through a connector 17, and drives the honing head 18 to rotate. A guide rod 11 is slidably connected inside the rotating shaft 13. One end of the guide rod 11 extends out of the rotating shaft 13 and is connected to the power output end of the telescopic oil cylinder 9, and the other end extends out of the rotating shaft 13 and is connected to the inside of the honing head 18, and controls the expansion and contraction of the honing head 18 with the reciprocating drive of the telescopic oil cylinder 9;

An adjusting shaft 19.4 is connected to the support column 19.2. The two ends of the adjusting shaft 19.4 are connected with the frame plate 19.5 and control the relative or reverse movement of the frame plate 19.5, so that the distance between the frame plates 19.5 can be adjusted according to the size of the workpiece, and thus the concentricity between the workpiece placed on the frame plates 19.5 and the polishing wheel can be adjusted, improving the polishing efficiency.

[0038] Further, as Figure 5 shown, the guiding bracket 16 includes symmetrically arranged support arms 16.1. A guiding wheel 16.2 for mounting the rotating shaft 13 is connected between the two support arms 16.1, which can provide a supporting and guiding effect for the fixed sleeve.

Then, the reciprocating motor 3 and the rotary motor 10 are started. The reciprocating motor 3 drives the driven wheel 5 to rotate through the driving wheel 2, and the first transmission sprocket 6 coaxially connected with the driven wheel 5 rotates synchronously. The first transmission sprocket 6 is connected with the second transmission sprocket 15 through the transmission chain 24. At the same time, the walking trolley 8 is connected with the transmission chain 24 to form a closed loop, so that the walking trolley 8 moves on the slide rail 7 as the transmission chain 24 rotates, and the honing head 18 moves into the workpiece. After that, the telescopic oil cylinder 9 is started, and the oilstone 18.3 protrudes through the guide rod 11, and the honing head 18 forms an unfolded state. Under the driving action of the rotary motor 10, the unfolded honing head 18 can be driven by the rotary shaft 13 to polish the workpiece.
