Description

Technical Field

[0001] This invention relates to the field of connecting rod plate production equipment technology, and in particular to an automatic assembly equipment for connecting rod plates. Background Technology

[0002] Connecting rod plates are commonly used in fitness equipment. These plates have assembly holes at their ends, into which bearings and retaining rings are installed. The necessary equipment for assembly includes bearing assembly machines and retaining ring assembly machines. The assembly process requires assembling the bearings first, followed by the retaining rings. Current assembly methods often involve manually grasping the connecting rod plate and placing it on the corresponding assembly fixture. Connecting rod plates typically require assembly at both ends, and positioning on the fixture necessitates adjustment to ensure accurate placement of the bearings or retaining rings. However, manual placement requires experienced workers, is highly subjective, and cannot meet the demands of extended operation. Bearing assembly machines and retaining ring assembly machines are located in different positions, often requiring manual grasping and movement, followed by recalibration on the corresponding fixture. This results in assembly quality and efficiency that fail to meet production requirements. Therefore, it is necessary to design an automated connecting rod plate assembly machine that can improve assembly quality and efficiency and achieve automated production. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic assembly equipment for connecting rod plates.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

Subsequently, the connecting rod plate is clamped by the flipping fixture of the translation and flipping mechanism, and flipped onto the snap ring assembly mechanism by the flipping cylinder for snap ring assembly. After the snap ring assembly mechanism completes the snap ring assembly, the connecting rod plate is placed into the unloading bin by the unloading mechanism, which improves the assembly quality and assembly efficiency. Automated production realizes the automatic assembly of the connecting rod plate without the need for manual operation and correction. Attached Figure Description

The bearing mounting frame has a pusher hole at the top and a fixture hole at the bottom. The bearing assembly machine is mounted on the top of the bearing mounting frame, and its output part passes through the pusher hole and is installed with the bearing pusher to move it up and down to assemble the bearing onto the connecting rod plate. The bearing pressing fixture is mounted on the bearing mounting frame, and a positioning cylinder for driving the bearing pressing fixture to cooperate with the bearing assembly machine is installed through the fixture hole. The first hopper mounting frame is bolted to the bearing mounting frame. The bearing feeding cylinder and the bearing hopper are respectively mounted on the first hopper mounting frame. The bottom of the bearing hopper has a bearing discharge rack with an opening for the bearing to fall into the bearing discharge rack. The bearing feeding cylinder pushes the bearing pusher plate to push the bearing from the bearing discharge rack to the bearing pressing fixture.

5. The automatic assembly equipment for connecting rod plates as described in claim 4, characterized in that: The bearing assembly machine is a cylinder. The bearing pressing fixture includes a base plate, an assembly seat, a positioning block, and a mandrel. The base plate is fixed to the bearing mounting bracket by bolts. The assembly seat is mounted on the base plate and has a positioning groove that communicates with the base plate vertically. The positioning block is embedded in the positioning groove and has a positioning hole. The mandrel is movably mounted in the positioning hole and is pushed by a positioning cylinder to move within the positioning hole to position the bearing.

6. The automatic assembly equipment for connecting rod plates as described in claim 1, characterized in that: The translation and flipping mechanism also includes a sliding assembly, which is mounted on the frame between the bearing assembly mechanism and the snap ring assembly mechanism by means of a fixed seat and bolts. The sliding assembly includes a second rodless cylinder and a second slide block slidably mounted on its slide rail. The flipping cylinder is mounted on the second slide block by means of a mounting seat and bolts. The flipping clamp is mounted on the output part of the flipping cylinder.

7. The automatic assembly equipment for connecting rod plates as described in claim 6, characterized in that: The flipping fixture includes a drive cylinder and two clamping blocks arranged vertically. The drive cylinder is mounted on the output part of the flipping cylinder via a rotating connecting plate and bolts. The drive cylinder is provided with a clamping block seat and a vertically arranged sliding groove. The two clamping blocks are slidably installed in the sliding groove and driven by the drive cylinder to move the two clamping blocks closer to or away from the connecting rod plate.

8. The automatic assembly equipment for connecting rod plates as described in claim 1, characterized in that: The snap ring assembly includes a snap ring mounting bracket, a snap ring guide block, a snap ring pressure sleeve, and a second hopper mounting bracket. The snap ring mounting bracket is bolted to the frame between the bearing assembly mechanism and the unloading mechanism. The snap ring assembly machine is mounted on the snap ring mounting bracket via a fixed connecting plate and bolts. Its output part is mounted to the snap ring pressure sleeve. The snap ring pressure sleeve has a downward-facing mounting cavity for mounting the snap ring guide block. The output part of the snap ring assembly machine moves downward to place the snap ring guide block on the connecting rod plate of the snap ring pressing fixture, or to retract the snap ring guide block from the snap ring pressing fixture. The second hopper mounting bracket is bolted to the snap ring mounting bracket for mounting the snap ring feeding assembly.

9. The automatic assembly equipment for connecting rod plates as described in claim 8, characterized in that: The circlip feeding cylinder and the circlip hopper are respectively installed on the second hopper mounting frame. The bottom of the circlip hopper is provided with a circlip discharge rack and an opening for circlip discharge. The circlip feeding cylinder pushes the circlip pusher plate to push the circlip from the circlip discharge rack to the circlip guide block on the circlip pressing fixture. The circlip assembly machine pushes the circlip pressing sleeve down to push the circlip along the circlip guide block to assemble it onto the connecting rod plate.

10. The automatic assembly equipment for connecting rod plates as described in claim 9, characterized in that: The snap ring assembly machine is a cylinder. The snap ring guide block has an insertion hole at its top. The snap ring sleeve has an installation groove on its side wall that communicates with the installation cavity and is equipped with a switching cylinder. Its output part is equipped with a plug rod that passes through the installation groove to insert or exit the insertion hole for placing or retracting the snap ring guide block.
