A tooling and method for adjusting the installation clearance of a double supporting pulley

Abstract

The present invention provides a tooling and method for adjusting the installation clearance of a double supporting pulley. The tooling includes a clearance adjusting seat and a fixed bracket. During adjustment, the positioning plate of the fixed bracket is pre-installed on both sides of the wheel axle hub combination sliding table station of the supporting pulley assembly line using bolts. The size of the T-shaped opening block matches the size of the positioning block. Before starting the double supporting pulley assembly, the matching clearance adjusting seat is installed on the fixed bracket. The present invention can play a limiting role during the bearing pressing process, preventing the pressing head from continuing to move downward after being pressed in place, thereby ensuring the assembly clearance. It can meet the requirement of one-time assembly forming on the assembly line without subsequent manual interference, while ensuring product quality and assembly consistency.

Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical assembly, and particularly relates to a tooling and method for adjusting the installation gap of double carrier rollers on a carrier roller assembly line. Background Art

[0002] During the assembly process of the double carrier roller assembly on the carrier roller assembly line, since the carrier roller shaft, the oil seal cover assembly and the deep groove ball bearing are coaxial, there is no limit when pressing the deep groove ball bearing. After being pressed in place, it will continue to move downward, pressing the oil seal cover assembly too deep, resulting in the double carrier roller assembly being unable to rotate normally in the free state after assembly, not meeting the quality requirements. After the product is taken off the production line, manual gap adjustment is required, which not only wastes manpower but also cannot guarantee product quality and assembly consistency. Summary of the Invention

[0003] (1) Technical Problems to be Solved

[0004] The present invention provides a tooling and method for adjusting the installation gap of double carrier rollers to solve the problem of adjusting the gap between the oil seal cover assembly and the double carrier roller shaft when pressing the deep groove ball bearing, ensuring a reasonable installation gap for the double carrier rollers taken off the assembly line and enabling normal rotation in the free state.

[0005] (2) Technical Solutions

[0006] To solve the above technical problems, the present invention provides a tooling for adjusting the installation gap of double carrier rollers, which includes a gap adjustment seat and a fixed bracket; wherein,

[0007] The gap adjustment seat includes a support block and a positioning block, and is used to adjust the gap between the carrier roller shaft with a fixed size and the oil seal cover assembly; wherein, the lower part of the support block is a cuboid structure for supporting the main structure, and the highest point of a partial arc of a cylinder is at the upper left part of the cuboid structure for abutting against the double carrier roller to fix the position; the positioning block is composed of two upper and lower cuboids, and the lower cuboid is connected to the bottom of the lower cuboid of the support block. The positioning block cooperates with the T-shaped opening block in the fixed bracket to fix the tooling;

[0008] The fixed bracket includes a T-shaped opening block and a positioning plate, and is used to connect the gap adjustment seat and the wheel hub combination slide of the carrier roller assembly line shaft; wherein, the T-shaped opening block is a cuboid structure with a T-shaped notch processed in the middle, and is used to cooperate with the positioning block of the gap adjustment seat to fix the gap adjustment seat; the positioning plate is a cuboid substrate processed with threaded holes, and is used to install the fixed bracket on the carrier roller assembly line. The T-shaped opening block is fixedly connected to the positioning plate.

[0009] Furthermore, a threaded hole is processed at each of the four corners of the positioning plate.

[0010] Furthermore, the T-shaped opening block is welded to the positioning plate.

[0011] Furthermore, the positioning block is composed of two cuboids with equal lengths, one on top of the other.

[0012] Furthermore, the width of the lower cuboid of the positioning block is greater than that of the upper cuboid.

[0013] In addition, the present invention also provides a method for adjusting the installation clearance of a double-support belt pulley. This method uses the above-mentioned tooling. There are two clearance adjustment seats and two fixed brackets respectively. During adjustment, the positioning plates of the fixed brackets are pre-installed on both sides of the pulley shaft hub combination sliding table station of the belt pulley assembly line using bolts. The size of the T-shaped opening block matches the size of the positioning block. Before starting the assembly of the double-support belt pulley, the matching clearance adjustment seat is installed on the fixed bracket, and the program is started for the assembly of the double-support belt pulley. When pressing the deep groove ball bearing, the top of the clearance adjustment seat abuts against the hub of the double-support belt pulley. The clearance adjustment seat slides with the sliding table to the bearing pressing station. The main shaft of the press moves downward, presses the bearing in place and retains an appropriate clearance. The double-support belt pulley assembly can rotate normally in the free state after being assembled offline.

[0024] This embodiment provides a tool for adjusting the installation gap of the double support pulleys, and its structure is as follows: Figure 1 As shown, it is composed of a gap adjustment seat 1 and a fixed bracket 2.

[0025] like Figure 2 As shown, the gap adjustment seat 1 is composed of a support block 1-1 and a positioning block 1-2, and is used to adjust the gap between the fixed-size dual-pulley axle and the oil seal cover assembly. Among them, the lower part of the support block 1-1 is a rectangular parallelepiped structure, which is used to support the main structure. The upper left part of the rectangular parallelepiped structure is the highest point of the partial arc of the cylinder, which is used to support the dual-pulley for position fixing. The positioning block 1-2 is composed of two upper and lower rectangular parallelepipeds of equal length. The lower rectangular parallelepiped is connected to the bottom of the lower rectangular parallelepiped of the support block 1-1. The width of the lower rectangular parallelepiped is greater than that of the upper rectangular parallelepiped. The positioning block 1-2 cooperates with the T-shaped opening block 2-1 in the fixed bracket 2 for tooling fixation.

[0026] like Figure 3 As shown, the fixed bracket 2 is composed of a T-shaped opening block 2-1 and a positioning plate 2-2, and is used to connect the gap adjustment seat and the wheel hub assembly slide of the support roller assembly line. Among them, the T-shaped opening block 2-1 is a rectangular structure with a T-shaped notch in the middle, which is used to cooperate with the positioning block 1-2 of the gap adjustment seat 1 to fix the gap adjustment seat 1. The positioning plate 2-2 is a rectangular base plate with a threaded hole on each of the four corners, which is used to install the fixed bracket 2 on the support roller assembly line, and the T-shaped opening block 2-1 is welded to the positioning plate 2-2.

[0027] The method of adjusting the installation clearance of the double support pulleys using the above-mentioned tooling is as follows:

[0028] There are two clearance adjustment seats 1 and two fixed brackets 2 each.
