[0005] The utility model provides an eccentric type spindle box assembly tool, which includes a right guide frame and a left guide frame arranged in parallel. The upper surfaces of the left guide frame and the right guide frame are both flat. Front brackets are arranged on the front lower sides of the left guide frame and the right guide frame, and rear brackets are arranged on the rear lower sides of both. Sliding seats are respectively arranged above the front and rear sides of the upper surface of the left guide frame and above the front and rear sides of the upper surface of the right guide frame. Each sliding seat can slide along the upper surface of its corresponding left guide frame or right guide frame. A transmission bracket is arranged between the left guide frame and the right guide frame. A rocker arm passes through the upper part of the transmission bracket. The rocker arm can rotate and can move axially. One end of the rocker arm is connected with a baffle, and a fixing plate is connected to the upper side of the baffle.

[0006] Further, the sliding seat includes a roller bracket, a fixed shaft, a shaft sleeve, and a cylindrical roller bearing. The fixed shaft is fixed to the lower part of the roller bracket through an outer snap ring. The inner ring of the cylindrical roller bearing is in interference fit with the fixed shaft. The shaft sleeve is arranged outside the fixed shaft and abuts against both outer sides of the inner ring of the cylindrical roller bearing.

[0007] Further, the left guide frame and the right guide frame and the corresponding front brackets are of an integral structure. The left guide frame and the right guide frame are attached to the corresponding rear brackets and are independent of the rear brackets.

[0008] Furthermore, pressing blocks are arranged at the positions corresponding to the rear brackets on the upper sides of the left guide frame and the right guide frame. The pressing blocks are used to make the left guide frame and the right guide frame closely adhere to the corresponding rear brackets.

[0009] Advantageous Effects of the Utility Model

[0010] The utility model can adjust the eccentric main shaft with different sizes and weights during installation through two adjustable rear brackets, and use the front bracket and the rear bracket as supports. After the main shaft box is fixed with bolts to the four sliding seats above the left guide frame and the right guide frame and the fixing plate, rotate the swing arm, and cooperate with hoisting to move the main shaft box in place for installation, improving the installation efficiency and safety of the eccentric main shaft box.

Specific Embodiments

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

[0016] Front brackets 3 are provided on the front lower sides of the left guide frame 2 and the right guide frame 1, and the left guide frame 2 and the right guide frame 1 and the corresponding front brackets 3 are of an integral structure; rear brackets 4 are provided on the rear lower sides, and the left guide frame 2 and the right guide frame 1 are in contact with the corresponding rear brackets 4 and are all independent of each other. Moreover, pressing blocks 15 are provided at the positions corresponding to the rear brackets 4 on the upper sides of the left guide frame 2 and the right guide frame 1, and the pressing blocks 15 are used to make the left guide frame 2 and the right guide frame 1 closely adhere to the corresponding rear brackets 4.

[0017] Sliding seats 5 are respectively arranged above the front and rear sides of the upper surface of the left guide frame 2 and above the front and rear sides of the upper surface of the right guide frame 1. The sliding seat 5 includes a roller bracket 10, a fixed shaft 11, a bushing 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 in interference fit with the fixed shaft 11. The bushing 12 is arranged outside the fixed shaft 11 and abuts against the outer sides of both sides of the inner ring of the cylindrical roller bearing 13. Each sliding seat 5 can rotate through the outer ring of the cylindrical roller bearing 13 to slide along the upper surface of its corresponding left guide frame 2 or right guide frame 1.
