DETAILED DESCRIPTION

[0015] As shown in the accompanying drawings, this embodiment provides an eccentric spindle box assembly, including a right guide frame 1 and a left guide frame 2 arranged in parallel, and the upper surfaces of the left guide frame 2 and the right guide frame 1 are both flat surfaces serving as guide rail surfaces.

[0016] A front bracket 3 is provided on the front lower side of the left guide frame 2 and the right guide frame 1, and the left guide frame 2 and the right guide frame 1 are an integral structure with the corresponding front bracket 3; a rear bracket 4 is provided on the rear lower side, and the left guide frame 2 and the right guide frame 1 are attached to the corresponding rear bracket 4 and are independent of the rear bracket 4, and a pressure block 15 is provided on the upper side of the left guide frame 2 and the right guide frame 1 at a position corresponding to the rear bracket 4, and the pressure block 15 is used to make the left guide frame 2 and the right guide frame 1 tightly attached to the corresponding rear bracket 4.

[0017] Slide seats 5 are respectively arranged on the upper front and rear sides of the upper surface of the left guide frame 2 and the upper front and rear sides of the upper surface of the right guide frame 1. The slide seat 5 includes a roller bracket 10, a fixed shaft 11, a sleeve 12, and a cylindrical roller bearing 13. The fixed shaft 11 is fixed to the lower part of the roller bracket 10. The inner ring of the cylindrical roller bearing 13 is interference fit with the fixed shaft 11. The sleeve 12 is arranged outside the fixed shaft 11 and supports the outer sides of the inner ring of the cylindrical roller bearing 13. Each slide seat 5 can slide along the upper surface of the corresponding left guide frame 2 or right guide frame 1 by rotating the outer ring of the cylindrical roller bearing 13. A transmission bracket 6 is arranged between the left guide frame 2 and the right guide frame 1, and a rocker arm 7 is arranged through the upper part of the transmission bracket 6. The rocker arm 7 can rotate and move axially. One end of the rocker arm 7 is connected to a baffle 8, and the upper side of the baffle 8 is connected to a fixing plate 9.
