[0038] like Figures 1 to 4 As shown, the inner hole processing device of the gas spring guide sleeve of this embodiment includes a frame 11, a mounting seat 12, a first chamfering unit 15, a second chamfering unit 16 and an inner hole cleaning unit 17.

[0039] Furthermore, there are two mounting seats 12, which are relatively arranged on the frame 11 and are generally fixed with bolts or welded. The gap between the two mounting seats 12 forms a transportation channel 13 for the gas spring guide sleeve. The gas spring guide sleeve passes through multiple processes along the transportation channel 13 in sequence. A number of corresponding through holes 14 are opened on the two mounting seats 12. These through holes 14 are circular through holes that can provide channels for shafts, rods, etc.

[0040] like Figure 2 The front end of the transport channel 13 is the feed end, and the first chamfering unit 15, the second chamfering unit 16 connected to the first chamfering unit, and the inner hole cleaning unit 17 are sequentially arranged at the feed end. The first chamfering unit 15 has a first tightening cylinder 151 and a first inner chamfering knife 152 driven by a servo motor. The telescopic rod of the first tightening cylinder 151 passes through the through hole 14 of the mounting seat 12, and the first inner chamfering knife 152 extends into the through hole 14 and corresponds to the telescopic rod. When the gas spring guide sleeve is positioned at the first inner chamfering station, the telescopic rod of the first tightening cylinder 151 abuts against the sealing end of the outer sleeve of the gas spring, and one end of the outer sleeve equipped with the guide sleeve abuts against the mounting seat 12. The first inner chamfering knife 152 extends into the through hole 14 and works under the drive of the servo motor to chamfer the end face of the compressed guide sleeve.

[0041] Combination Figure 2As shown, the second chamfering unit 16 has a second tightening cylinder 161 and a second inner chamfering knife 162 driven by a servo motor, the telescopic rod of the second tightening cylinder 161 passes through the through hole 14 of the mounting seat 12, and the second inner chamfering knife 162 extends into the through hole 14 and corresponds to the telescopic rod. When the gas spring guide sleeve is positioned at the second inner chamfering station, the telescopic rod of the second tightening cylinder 161 abuts against the sealing end of the gas spring outer sleeve, one end of the outer sleeve equipped with the guide sleeve abuts against the mounting seat 12, the second inner chamfering knife 162 extends into the through hole 14, and works under the drive of the servo motor to perform secondary chamfering on the end face of the compressed guide sleeve.

[0042] Generally, after two more chamfering processes, there will be debris left on the end face of the guide sleeve and in the guide hole, so the end face and the guide hole need to be cleaned. Figure 2 , Figure 3 and Figure 4 In the figure, the inner hole cleaning unit 17 comprises a third tightening cylinder 171, a driving component 172 and a cleaning component 173, the telescopic rod of the third tightening cylinder 171 passes through the through hole 14 of the mounting seat 12, the driving component 172 comprises a driving motor 1721 and a slewing bearing seat 1722, the driving motor 1721 and the slewing bearing seat 1722 are an integrated structure, and are an integral product available on the market.

[0043] To facilitate processing and installation, the first tightening cylinder 151, the second tightening cylinder 161 and the third tightening cylinder 171 are located on the same side and are arranged on the mounting seat 12; the first inner chamfering knife 152, the second inner chamfering knife 162 and the cleaning component 173 are located on the other side and are arranged on the mounting seat 12.

[0044] In this embodiment, the slewing bearing seat 1722 can bear the head of the gas spring guide sleeve and is driven to rotate by the driving motor 1721; in order to increase the friction between the two, a slewing bearing 1723 is arranged on the inner surface of the slewing bearing seat 1722, and the slewing bearing 1723 is provided with a rotating ring, the material of the rotating ring is rubber, the guide sleeve is against the rotating ring, and rotates rapidly with the slewing bearing 1723.

[0045] On the basis of the above structure, the cleaning component 173 includes a telescopic cylinder 1731 and a cleaning rod 1732 located at the front end of the telescopic cylinder 1731. The cleaning rod 1732 can pass through the slewing bearing seat 1722 and extend into the guide hole of the gas spring guide sleeve. Under the driving action of the driving motor 1721, the cleaning rod 1732 is set to be stationary, and the guide sleeve rotates rapidly with the slewing bearing 1723, thereby cleaning the debris in the guide hole and the chamfered end face.

[0046] Furthermore, the telescopic cylinder 1731 is horizontally fixed on the frame 11, the diameter of the cleaning rod 1732 is slightly smaller than the inner diameter of the guide hole 14 of the gas spring guide sleeve, and a cleaning element 1733 is provided on the surface of the cleaning rod 1732. Preferably, the cleaning element 1733 is a clean cloth or cotton cloth.

[0047] In actual use, it was found that the guide sleeve was fixed at the first and second inner chamfering stations, and the guide sleeve was rotated and pressed against at the inner hole cleaning station. It was known that the pressing force required for the first and second inner chamfering stations was relatively large. Therefore, the first tightening cylinder 151 and the second tightening cylinder 161 have the same structure, and the specifications of the third tightening cylinder 171 are smaller than those of the second tightening cylinder 161.

[0048] The tightening cylinder and the inner chamfering cutter used in the utility model are both commercially available products.

[0049] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
