Description

Mandrel riveting tool for retractor

Technical Field

The utility model relates to production equipment for a reel, in particular to a mandrel riveting tool for a reel.

Background Art

The retractor is an important component of the automobile seat belt system, which mainly includes a shell, a rotating part is arranged in the shell, and a core shaft is riveted and connected to the rotating part. The traditional core shaft riveting mechanism is generally provided with a base. During processing, it is necessary to place the shell pre-installed with the core shaft on the base, and then control the action of the clamping mechanism to position and clamp the shell, and then control the riveting part to descend to rivet the core shaft into the shell. The defect of this structure is: after each riveting is completed, it is necessary to control the clamping mechanism to loosen the shell, and then manually replace the shell, and then clamp and position the new shell through the clamping mechanism. During the process of replacing and positioning the shell, the riveting operation cannot be performed, resulting in low riveting efficiency and inability to achieve fast riveting processing.

Utility Model Content

In view of the shortcomings of the background technology, the technical problem to be solved by the utility model is to provide a mandrel riveting tool for a retractor for solving the above-mentioned problem.

To this end, the utility model is implemented by adopting the following scheme:

The mandrel riveting tooling of the retractor is characterized in that it includes a rotating disk, a plurality of placement grooves are circumferentially arranged on the rotating disk, a positioning groove is arranged at the bottom of the placement groove, a moving frame is arranged on one side of the rotating disk corresponding to the placement groove, a positioning piece that can be inserted into the retractor is arranged on the moving frame, a riveting plate is arranged above the rotating disk, the riveting plate is movably arranged on a lifting seat, and a spring is tightly arranged between the riveting plate and the lifting seat.

One end of the lifting seat is connected to the piston rod of the oil cylinder, and the cylinder body of the oil cylinder is fixed on the frame.

A guide column is extended on the top of the riveting plate, and the guide column passes through the guide hole on the lifting seat. A positioning head is screwed on the top of the guide column, and the positioning head is pressed tightly on the top of the lifting seat.

Each moving frame is connected with the piston rod of the corresponding cylinder, and the cylinder body of each cylinder is arranged on the rotating disk.

The mandrel riveting tooling of the retractor of the above technical solution has a simple structure and a reasonable design. By setting a rotating disk, the shell waiting for riveting can be placed in its placement groove, and as the rotating disk rotates, it is sent to the riveting station and cooperates with the riveting disk to realize the riveting operation of the mandrel. At the same time, when the riveting process is being carried out, the shells in the remaining placement grooves can be easily replaced, and the replacement operation is simple, which effectively improves the efficiency of the riveting process; in addition, by setting a spring between the riveting disk and the lifting seat, the extrusion force during riveting has an incremental increase process, which further ensures the stability and reliability of the riveting.

BRIEF DESCRIPTION OF THE DRAWINGS

The utility model has the following drawings:

Fig. 1 is a schematic diagram of the structure of the utility model;

FIG2 is a cross-sectional view of the riveting plate and the lifting seat of the utility model.

DETAILED DESCRIPTION

As shown in the figure, the mandrel riveting tooling of the retractor disclosed in the utility model includes a rotating disk 2, which is connected to the output end of the rotating drive motor, and a plurality of placement grooves 6 are arranged around the rotating disk 2, and a positioning groove 5 is arranged at the bottom of the placement groove 6. The rotating disk 2 is provided with a moving frame 3 on one side corresponding to the placement groove 6, and a positioning member 4 that can be inserted into the retractor is arranged on the moving frame 3. Specifically, each moving frame 3 is connected to the piston rod of the corresponding cylinder, and the cylinder body of each cylinder is arranged on the rotating disk 2. A riveting plate 10 is arranged above the rotating disk 2, and the riveting plate 10 is movably arranged on the lifting seat 8, and a spring 9 is tightly arranged between the riveting plate 10 and the lifting seat 8. One end of the lifting seat 8 is connected to the piston rod of the oil cylinder 7, and the cylinder body of the oil cylinder 7 is fixed on the frame. By controlling the movement of the oil cylinder 7, the lifting seat 8 can be driven to rise and fall. A guide column 12 is extendedly provided on the top of the riveting plate 10, and the guide column 12 passes through the guide hole on the lifting seat 8. A positioning head 11 is screwed on the top of the guide column 12, and the positioning head 11 is tightly pressed on the top of the lifting seat 8 to realize the movable setting of the riveting plate 10. At the same time, the lifting seat 8 is positioned and fixedly connected with a transmission seat 13, and the transmission seat 13 is connected to the piston rod of the cylinder 7.

The working principle of the utility model is to first place the retractor shell with the mandrel pre-placed thereon into the placement groove 6, and the positioning groove 5 corresponds to the outer convex part of the side of the retractor shell, thereby ensuring the positioning and placement of the retractor shell, and then the cylinder drives the corresponding movable frame 3 to move, so that the positioning piece 4 is inserted into the groove on the shell, further limiting the position of the retractor, and at the same time, the rotating disk 2 drives the shell body to the riveting station, and the oil cylinder 7 drives the riveting plate 10 to descend to perform riveting processing on the mandrel. After the riveting is completed, the riveting plate 10 is reset, the rotating disk 2 continues to rotate to send the shell out and the cylinder drives the movable frame 3 to move in the opposite direction, and the positioning piece 4 is detached from the shell. At this time, the shell with the mandrel riveted can be taken away and replaced with a new shell of the mandrel to be riveted.

The structure of the utility model can place the shell waiting for riveting in its placement groove by setting a rotating disk, and send it to the riveting station as the rotating disk rotates to cooperate with the riveting disk to realize the riveting operation of the core shaft. At the same time, when the riveting process is being carried out, the shells in the remaining placement grooves can be conveniently replaced, and the replacement operation is simple, which effectively improves the efficiency of the riveting process; in addition, by setting a spring between the riveting disk and the lifting seat, the extrusion force during riveting has an incremental increase process, which further ensures the stability and reliability of the riveting.
