Description

Technical Field

[0002] Spring is a common component in the mechanical field, which is used to realize the functions of buffering, resetting and pre-tightening of a certain structure. When installing spring parts, manual assembly is usually adopted. The spring to be installed is first compressed manually or with tools, and then the compressed spring is assembled with the receiving hole or limiting cylinder of the workpiece. In this way, the labor intensity of the operator is relatively high, and when compressing the spring, the spring is very easy to bend, so that there is a deviation between the compression direction of the spring and the axial direction of the spring, resulting in inaccurate installation position of the spring on the workpiece, reducing the quality of the assembly. In addition, the efficiency of manual assembly is low, and there are safety hazards to the personal safety of the operators. Some existing spring installation equipment uses a clamp to fix the spring when compressing the spring, but the spring models and sizes are different, and the clamp must be frequently disassembled and replaced, which greatly affects the work efficiency.

[0019] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:

[0020] like Figures 1 to 3 As shown, a spring anti-lateral bending device includes a feeding mechanism 1, a positioning mechanism 2 and a compression mechanism 3. The positioning mechanism 2 includes a positioning cylinder 21, an upper V-shaped pressing block 23 and a lower V-shaped pressing block 22. The upper V-shaped pressing block 23 is fixedly connected to the telescopic end of the positioning cylinder 21 through a moving plate 24. The lower V-shaped pressing block 22 is provided directly below the upper V-shaped pressing block 23. The side of the lower V-shaped pressing block 22 is open and provided with a feeding mechanism 1. The spring is located in the lower V-shaped pressing block 22. One end of the lower V-shaped pressing block 22 is provided with a through hole, which connects the positioning mechanism 2 and the compression mechanism 3. The positioning cylinder 21 drives the upper V-shaped pressing block 23 to move, and the upper V-shaped pressing block 23 cooperates with the lower V-shaped pressing block 22 to clamp and fix the spring to be compressed, so that the radial direction of the spring is fixed and cannot be bent. The movable plate 24 is provided with symmetrically distributed limiting bolts 241, and the lower V-shaped pressing block 22 is provided with a groove 221 matching the limiting bolts 241, and the limiting bolts 241 are threadedly connected with the movable plate 24. When the movable plate 24 moves down with the upper V-shaped pressing block 23 to contact the spring, one end of the limiting bolt 241 contacts the bottom surface of the groove 221 to prevent the upper V-shaped pressing block 23 from causing irreversible deformation of the spring in the radial direction. By adjusting the length of the limiting bolts 241 screwed out of the movable plate 24, springs of different diameters can be adapted.

[0021] The unloading mechanism 1 includes an unloading platform 11, an unloading cylinder 12 and a bracket 113. The bracket 113 is provided on the bottom surface of the unloading platform 11. The unloading end 112 of the unloading platform 11 contacts the side of the lower V-shaped pressing block 22. The unloading cylinder 12 is provided below the bracket 113. A clamping plate 111 is provided on the unloading platform 11. The clamping plate 111 is perpendicular to the spring, and the spring slides along the clamping plate 111. The spring is clamped with the clamping plate 111 on the unloading platform 11. The clamping plate 111 limits the axial position of the spring, and the spring can slide radially along the clamping plate 111 toward the positioning mechanism 2. A base 123 is provided at the bottom of the unloading cylinder 12. A first push rod 121 and a second push rod 122 are provided at the telescopic end of the unloading cylinder 12. The first push rod 121 passes through the bottom of the lower V-shaped pressing block 22, and the second push rod 122 passes through the unloading end 112. The first push rod 121 is longer than the second push rod 122. The unloading cylinder 12 drives the first push rod 121 and the second push rod 122 to move simultaneously. The first push rod 121 first pushes out the spring in the lower V-shaped pressing block 22, and the second push rod 122 pushes the spring of the unloading end 112 into the lower V-shaped pressing block 22. A support frame 124 is provided below the first push rod 121, and a roller is provided on the top of the support frame 124, and the roller is in rolling contact with the first push rod 121. The support frame 124 prevents the first push rod 121 from deforming and bending, and the roller can reduce the friction between the first push rod 121 and the first push rod 121.

[0022] The compression mechanism 3 comprises a compression cylinder 31, a top block 33, a pressure rod and a guide rod 32. The telescopic end of the compression cylinder 31 is fixedly connected to the top block 33, the top block 33 is slidably connected to the guide rod 32, and the pressure rod is detachably connected to the top block 33. The top block 33 is provided with a positioning groove for matching the pressure rod, and a V-shaped groove 34 is provided on one side of the through opening close to the compression mechanism 3. One end of the pressure rod is embedded in the positioning groove, and the other end is placed in the V-shaped groove 34. The pressure rod passes through the through opening and contacts with one end of the spring. According to the length and diameter of the spring, a suitable pressure rod is selected and assembled on the top block 33. The compression cylinder 31 drives the pressure rod to enter the lower V-shaped pressure block 22 along the V-shaped groove 34 to contact with one end of the spring, and compress the spring.

[0023] The working principle of the specific implementation of the utility model is as follows: the spring to be compressed is clamped on the unloading platform 11 through the clamping plate 111, and the spring slides along the unloading platform 11 to the unloading end 112. The unloading cylinder 12 is started, and the first push rod 121 first pushes out the spring in the lower V-shaped pressure block 22, and the second push rod 122 pushes the spring at the unloading end 112 into the lower V-shaped pressure block 22; the positioning cylinder 21 drives the upper V-shaped pressure block 23 to move downward, and the upper V-shaped pressure block 23 cooperates with the lower V-shaped pressure block 22 to fix the radial position of the spring to be compressed; the compression cylinder 31 drives the pressure rod to pass through the through port, and the pressure rod applies pressure to one end of the spring to compress the spring axially.
