[0030] The embodiment of the present invention provides a bidirectionally adjustable eccentric guide wheel device, comprising: a guide wheel mounting frame 1, a transverse guide wheel assembly 2 and a longitudinal guide wheel assembly 3, wherein:

[0031] The flange upper surface of the guide wheel mounting frame 1 is provided with a convex block, and the convex block is provided with a conical hole arranged along the width direction of the flange, and the conical hole is adapted to the conical shaft 6 of the transverse guide wheel assembly 2.

[0032] The tapered shaft 6 of the transverse guide wheel assembly 2 is inserted into the tapered hole, and the small shaft end of the tapered shaft 6 is pressed onto the guide wheel mounting frame 1 through an adjustment sleeve 9, a small shaft end stop washer 10 and a small shaft end nut 11 in sequence;

[0033] A longitudinal guide wheel 13 is installed on the middle shaft of the eccentric shaft 14 of the longitudinal guide wheel assembly 3, and small shafts are extended on both sides of the terminal shaft of the eccentric shaft 14. The small shaft on one side is adapted to be installed in the circular shaft hole, and the small shaft on the other side is adapted to be connected to the shaft hole on the support ear of the guide wheel mounting frame 1 through a shaft sleeve 16.

[0034] In this embodiment, the lower surface of the bottom flange of the guide wheel mounting frame 1 is the mounting surface, which is fixed by four mounting holes arranged at the four corners of the bottom flange. The bottom flange is also provided with four pin holes for positioning with the mounting base after the installation is completed.

[0035] At the same time, an oil cup 4 is installed on the support ear of the guide wheel mounting frame 1, and the oil cup 4 is connected with the lubricating oil channel inside the longitudinal guide wheel assembly 3 through the lubricating oil channel arranged on the support ear where the oil cup 4 is located.

[0036] In this embodiment, the transverse guide wheel assembly 2 also includes a transverse guide wheel 5, a large shaft end nut 7 and a large shaft end stop washer 8. The transverse guide wheel 5 is installed on one end of the large shaft of the tapered shaft 6 and is pressed against the shoulder of the tapered shaft 6 through the large shaft end nut 7 and the large shaft end stop washer 8.

[0037] At the same time, the thickness of the adjustment sleeve 9 is adjusted according to the pressing condition of the shaft end, so that the tapered shaft 6 is fully in contact with the tapered hole during pressing.

[0038] Furthermore, a lubricating oil passage is provided inside the tapered shaft 6, which passes from the small shaft end face to the transverse guide wheel 5. The oil cup 12 installed on the small shaft end face of the tapered shaft 6 is communicated with the internal lubricating oil passage. The small shaft end of the tapered shaft 6 is concentric with the tapered surface, and the eccentricity between the concentric line and the axis center line of the large shaft end of the tapered shaft 6 is e. Rotating and adjusting the tapered shaft 6 in the circumferential direction can achieve position adjustment of the transverse guide wheel 5 at 2 times the eccentricity e in the circumferential direction.

[0040] At the same time, the small shafts on both sides of the eccentric shaft 14 of the device are concentric, and the eccentricity between the concentric shaft and the centerline of the installation shaft of the middle longitudinal guide wheel 13 is f. Rotating and adjusting the eccentric shaft 14 in the circumferential direction can achieve the position adjustment of the longitudinal guide wheel 13 in the circumferential direction at 2 times the eccentricity f.

[0041] In this embodiment, a bidirectional adjustable eccentric guide wheel device that can be used in pair is formed by mirroring the longitudinal guide wheel assembly 3 along the central axis of the transverse guide wheel assembly 2.

[0042] In order to facilitate the understanding of the above technical solution, the following is an explanation with reference to examples, as follows:

[0043] In the above-mentioned bidirectional adjustable eccentric guide wheel device, the lower surface of the bottom flange of the guide wheel mounting frame 1 is the mounting surface, which can be fixed through 4 mounting holes on the bottom flange. 4 pin holes are also arranged on the bottom flange. After the installation is completed, it is positioned with the mounting base. A direction convex block is arranged on the upper surface of the flange of the guide wheel mounting frame 1. A longitudinal tapered hole is arranged on the convex block to match the tapered shaft of the transverse guide wheel assembly 2. A certain eccentricity is set between the axis of the transverse guide wheel 5 and the axis of the tapered surface of the tapered shaft. By rotating the tapered shaft, the transverse guide wheel 5 can be adjusted within the range of 2 times the axis in the transverse direction. Fine-tuning is performed; a circular axial hole is set on a side surface of the protrusion that is perpendicular to the longitudinal tapered hole. The axial hole is concentric with the axial hole on one side support ear of the guide wheel mounting frame 1, and is used to install and fix the longitudinal guide wheel assembly 3. The axis of the concentric axial hole is set with a certain eccentricity from the axis of the longitudinal guide wheel 13. By rotating the eccentric shaft of the longitudinal guide wheel 13, the longitudinal guide wheel can be fine-tuned within the longitudinal range of 2 times the axis. An oil cup 4 is installed on the support ear of the guide wheel mounting frame 1. The oil cup 4 is communicated with the lubricating oil channel inside the longitudinal guide wheel assembly 3 through the lubricating oil channel set on the support ear of the guide wheel mounting frame 1.

[0044] The transverse guide wheel assembly 2 is composed of a transverse guide wheel 5, a tapered shaft 6, a large shaft end nut 7, a large shaft end stop washer 8, an adjustment sleeve 9, a small shaft end stop washer 10, a small shaft end nut 11 and an oil cup 12. The transverse guide wheel 5 is installed on one end of the large shaft of the tapered shaft 6 and is pressed against the shoulder of the tapered shaft 4 through the large shaft end nut 7 and the large shaft end stop washer 8. The tapered shaft 6 of the transverse guide wheel assembly 2 matches the tapered hole on the guide wheel mounting frame 1. The small shaft end of the tapered shaft 6 is pressed against the guide wheel mounting frame 1 through the adjustment sleeve 9, the small shaft end stop washer 10 and the small shaft end nut 11 in sequence. The thickness of the adjusting sleeve 9 needs to be adjusted according to the tightening condition of the shaft end to ensure that the tapered shaft 6 is in full contact with the tapered hole on the guide wheel mounting frame 1 during tightening. A lubricating oil channel is arranged inside the tapered shaft 6 from the small shaft end face to the transverse guide wheel 5. An oil cup 12 is installed on the small shaft end face of the tapered shaft 6 and is connected to the internal lubricating oil channel. The small shaft end of the tapered shaft 6 is concentric with the tapered surface. The eccentricity between the concentric line and the axis centerline of the large shaft end of the tapered shaft 6 is e (determined according to actual adjustment requirements). By rotating and adjusting the tapered shaft 6 in the circumferential direction, the position adjustment of the transverse guide wheel 5 in the circumferential direction can be realized at 2 times the eccentricity e.

[0045] The longitudinal guide wheel assembly 3 is composed of a longitudinal guide wheel 13, an eccentric shaft 14, a spacer 15, a sleeve 16, a plug 17, an adjustment end cover 18, a spring washer 19 and a screw 20. The longitudinal guide wheel 13 is mounted on the middle section of the eccentric shaft 14, and small shafts extend from both sides of the middle section of the eccentric shaft 14. The small shaft on one side is matched with the shaft hole on the convex block of the guide wheel mounting frame 1, and the small shaft on the other side is matched with the shaft hole on the support ear of the guide wheel mounting frame 1 through the sleeve 16. The spacer 15, the longitudinal guide wheel 13, the sleeve 16 and the adjustment end cover 18 are sequentially mounted on the eccentric shaft 14, and the longitudinal guide wheel assembly 3 is axially fixed by the washer 19 and the screw 20. The adjustment end cover 18 is provided with a plug 17. The small shafts on both sides of the eccentric shaft 14 are concentric, and the eccentricity between the concentric shaft and the centerline of the mounting shaft of the middle longitudinal guide wheel 13 is e (determined according to actual adjustment requirements). Rotating and adjusting the eccentric shaft 14 in the circumferential direction can achieve position adjustment of the longitudinal guide wheel 13 in the circumferential direction at 2 times the eccentricity e.

[0046] The bidirectionally adjustable eccentric guide wheel device can be formed by mirroring the longitudinal guide wheel assembly 3 along the central axis of the transverse guide wheel assembly 2 to form a bidirectionally adjustable eccentric guide wheel device that can be used in pairs.

[0047] It can be known from the above technical scheme that the bidirectional adjustable eccentric guide wheel device provided in the above embodiment of the present invention integrates the transverse guide wheel assembly 2 and the longitudinal guide wheel assembly 3 into a whole, has a compact structure, and is easy to install. The mounting shaft of the transverse guide wheel assembly 2 adopts a tapered hole fit, has a large contact area, and has a strong load-bearing capacity. Both the transverse guide wheel assembly 2 and the longitudinal guide wheel assembly 3 can fine-tune the circumferential position of the guide wheel by rotating their respective eccentric shafts, adapt to the wear or slight deformation caused by the long-term use of the guide rail, ensure sufficient contact and pressure transmission between the guide wheel and the guide rail, and ensure the smooth operation of the equipment.
