Description

Technical Field

[0001] The utility model relates to the technical field of honing equipment, in particular to a honing machine main shaft device with an inner oil-passing structure. Background Art

[0002] In the prior art, honing equipment usually sprays external special cooling honing oil through a nozzle to the inner hole of the workpiece to be honed for honing cooling and chip removal. Because during the honing process, the gap between the inner hole of the workpiece and the honing working area is very small, and the cooling oil flows downward from the gap only by gravity, the flow rate is small, and the cooling and chip removal effects are not ideal, resulting in the waste heat in the cutting area cannot be "taken away" as soon as possible in the shortest time, which is easy to cause thermal deformation or "secondary quenching" and potentially affect the intrinsic quality of the product. In addition, the chips and powder generated during the honing process are not easy to be washed away in time, which will cause the cutting area of ​​the honing bar to be "blocked", thereby affecting the honing cutting efficiency and the service life of the honing bar, and it is difficult to obtain a better surface roughness of the honing inner hole.

[0003] To this end, it is necessary to design a honing machine spindle that can directly supply fluid to the honing cutting area. The honing spindle can directly provide special honing fluid for cooling or chip removal to the honing cutting area. The special cooling honing oil is sprayed into the inner hole cutting area of ​​the part to be honed through the internal channel of the honing tool, which can greatly improve the cooling and chip removal effects. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, a honing machine spindle device with an inner oil-passing structure is provided.

[0005] The utility model solves the technical problem by adopting a technical solution: a honing machine spindle device with an internal oil-through structure, comprising a spindle, a pulley support sleeve and an oil seal spacer.

[0006] The oil seal spacer is located between the main shaft and the pulley support sleeve, and oil seals are provided above and below the oil seal spacer. An annular oil groove is provided on the outer wall of the oil seal spacer, and an oil cavity is formed between the inner wall of the oil seal spacer and the main shaft. An oil hole connecting the annular oil groove and the oil cavity is provided in the oil seal spacer.

[0007] The outer side wall of the pulley support sleeve is provided with an oil inlet which is connected to the annular oil groove of the oil seal spacer.

[0008] The outer wall of the spindle is provided with a spindle oil port and a spindle oil outlet. The spindle oil port is connected to the spindle oil outlet located below the spindle oil port through the oil path in the spindle.

[0010] Furthermore, an oil-slinging pan fixedly mounted on the outside of the main shaft is provided below the oil seal below the oil seal spacer.

[0011] An oil passage for allowing oil leaking from the oil seal to pass through exists between the pulley support sleeve and the oil-slinging pan.

[0012] Furthermore, the spindle outer rotating sleeve is provided with a spindle sleeve, and the pulley support sleeve is fixedly connected with the spindle sleeve by bolts.

[0013] An oil overflow hole connected with the oil channel through a passage is arranged on the outer side wall of the main shaft sleeve, and an upwardly extending step is arranged on the inner side wall of the main shaft sleeve to block the oil channel from extending toward one side of the main shaft.

[0014] The remarkable effect of the utility model is that the oil seal spacer arranged in an annular manner cooperates with the oil circuit in the main shaft, thereby replacing the original cooling oil nozzle to spray oil from the inner hole of the workpiece to be honed from the outside; during the working process, the oil inlet does not rotate, the main shaft and the honing tool rotate synchronously, the oil enters the main shaft through the oil seal spacer, the main shaft oil outlet is connected to the honing tool, and the special cooling honing oil is directly sprayed into the inner hole cutting area of ​​the part to be honed through the internal channel of the honing tool, thereby greatly improving the cooling and chip removal effects.

[0022] Figure 1-Figure 4 The honing machine spindle device with an internal oil-through structure shown in the figure comprises a spindle 1, a pulley support sleeve 2 and an oil seal spacer 3.

[0023] The oil seal spacer 3 is located between the main shaft 1 and the pulley support sleeve 2, and oil seals 4 are provided above and below the oil seal spacer 3. An annular oil groove 32 is provided on the outer wall of the oil seal spacer 3, and an oil cavity 33 is formed between the inner wall of the oil seal spacer 3 and the main shaft 1. An oil hole 31 connecting the annular oil groove 32 and the oil cavity 33 is provided in the oil seal spacer 3.

[0024] An oil inlet 21 connected to the annular oil groove 32 of the oil seal spacer 3 is provided on the outer wall of the pulley support sleeve 2. A spindle oil port 11 and a spindle oil outlet 12 are provided on the outer wall of the spindle 1. The spindle oil port 11 is connected to the spindle oil outlet 12 located below the spindle oil port 11 through an oil passage 13 in the spindle.

[0025] The main shaft oil port 11 communicates with the oil chamber 33 and the oil passage 13 in the main shaft 1 .

[0026] The oil circuit connected to the honing tool is located in the main shaft 1 which rotates synchronously with the honing tool. The oil outlet of the main shaft 1 is connected to the honing tool to directly spray the special cooling honing oil into the inner hole cutting area of ​​the part to be honed through the internal channel of the honing tool, which greatly improves the cooling and chip removal effects.

[0027] An oil-slinging pan 5 fixedly mounted on the outside of the main shaft 1 is provided below the oil seal 4 below the oil seal spacer 3.

[0028] There is an oil passage 51 between the pulley support sleeve 2 and the oil-slinging pan 5 for the oil leaking from the oil seal 4 to pass through.

[0029] The main shaft 1 is externally rotated with a main shaft sleeve 6, and the pulley support sleeve 2 is fixedly connected with the main shaft sleeve 6 by bolts.

[0030] An oil overflow hole 61 communicating with the oil passage 51 through a passage is provided on the outer side wall of the main shaft sleeve 6 , and an upwardly extending step 62 is provided on the inner side wall of the main shaft sleeve 6 for preventing the oil passage 51 from extending toward the side of the main shaft 1 .

[0031] When passing the oil, the oil is introduced from the oil inlet 21 of the pulley support sleeve 2, passes through the annular oil groove 32 of the oil seal spacer 3, and then enters the oil chamber 33 through the oil hole 31, and then enters the oil passage 13 in the spindle 1 through the spindle oil port 11, and then communicates with the honing tool through the spindle oil outlet 12, and directly sprays the special cooling honing oil into the inner hole cutting area of ​​the part to be honed through the internal channel of the honing tool for cooling and chip removal;

[0032] When the oil seal 4 is not sealed and leaks, the oil flows out from the oil overflow hole 61 of the main shaft sleeve 6 after passing through the oil channel 51 through the oil slinger plate 5. The other side of the oil channel 51 is blocked by the step 62 of the main shaft sleeve 6, and the oil will not flow to the main shaft 1. That is, whether the oil seal 4 is sealed can be judged by whether there is oil overflowing from the oil overflow hole 61. If it is not sealed, the oil seal 4 should be replaced in time.
