Description

Technical Field

[0001] The utility model belongs to the technical field of shock-absorbing air bag processing, and in particular relates to a shock-absorbing air bag automatic material-removing and chip-removing tool. Background Art

[0002] The shock-absorbing air bag is a shock absorber installed on the car. It uses the principle of gas shock absorption to achieve shock absorption in bumpy conditions during the vehicle's movement, thereby improving the driving experience.

[0003] The shell of the shock-absorbing air bag is a plastic shell, which is in the shape of a special-shaped structure, and its main appearance includes a curved upper shell head and a curved lower shell part that expands outward. Therefore, the special-shaped shock-absorbing air bag shell is difficult to process in the workshop.

[0004] Specifically, during the processing of the plastic shell of the shock absorber air bag, many processing steps such as opening holes and grooves are required on the shell. During the processing, the injection-molded shell blank needs to be positioned by a fixture. At present, the positioning fixtures in the workshop are mainly positioned from the side by the pressure rods on the fixtures.

[0005] First of all, the disadvantage of this positioning method is that manual positioning is difficult and the positioning force cannot be controlled well. If the positioning force is too large, that is, the contact pressure locking force is too large, it is easy to cause deformation, indentation and other defects in the shell workpiece. Specifically, because the interior of the shell workpiece is a cavity structure, once the positioning force of the positioning structure is not well controlled, it is very easy to cause damage to the shell.

[0006] Insufficient positioning force can easily lead to over-feeding, and the stability of the workpiece cannot be guaranteed during processing.

[0007] At the same time, during the processing, a large amount of debris is generated on the shell workpiece due to the groove or hole opening process. The current manual material discharge after processing requires the workpiece to be removed from the fixture. During the removal process, the debris can easily enter the material trough in the fixture, which makes it difficult to clean the debris in the material trough and the cleaning is insufficient. The subsequent placement of the blank workpiece cannot be placed in parallel, resulting in unstable material discharge.

[0008] Moreover, the above processing method has more serious drawbacks: the loading, locking and unloading procedures are too complicated, resulting in low efficiency in batch processing. Utility Model Content

[0021] Preferably, the material and chip discharge mechanism comprises a base, and the top of the base is assembled and connected with a plurality of top columns corresponding to the material holes;

At the same time, when the debris enters the material hole and falls into the material hole, the debris is pushed out of the material hole during the process of pushing the top column upward, thereby preventing the debris from affecting the cleanliness of the material hole. At the same time, the top column that slides into the material hole also plays a role in cleaning the material hole, and uses friction to discharge the debris on the wall of the material hole and push it up to leave the material hole. In this way, the shell can discharge materials accurately and smoothly during the subsequent loading of the shell, thereby improving the stability of the discharge. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Example 1

[0042] like Figure 1-5As shown, a shock-absorbing air bag automatic material removal and chip removal tooling includes a feeding tooling 1 with two sides flushly arranged, and a plurality of material holes are opened on the feeding tooling 1. After the shock-absorbing air bag shell workpiece 4 with a special-shaped structure is discharged, the lower end position of the shell workpiece 4 is limited in the material hole, and the upper end position is larger than the material hole, so it is supported on the top of the material hole.

[0043] The above-mentioned loading tools 1 are fixedly connected by a plurality of connecting beams B. The connecting beams B are U-shaped and fixed on both sides by bolts.

[0044] The automatic material removal and chip removal tooling of the shock-absorbing air bag also includes a plurality of locking arm assemblies for locking the shock-absorbing air bag housing workpiece 4. That is, one locking arm assembly synchronously locks the two housing workpieces 4 on both sides.

[0045] The specific structure of the locking arm assembly is:

[0046] The locking arm assembly includes U-shaped arms 22 spaced apart on both sides, and an annular locking plate 21 is fixedly connected between the openings of the U-shaped arms 22; specifically, both ends of the U-shaped arm 22 are fastened to the top of the annular locking plate 21 by bolts.

[0047] During the material pressing process, the annular locking plate 21 presses the material on the edge of the upper port of the shell workpiece 4. Specifically, the center position of the annular locking plate 21 is an annular opening for the tool head on the processing equipment to enter.

[0048] A connecting fork arm 23 is fixedly connected between the side walls of the U-shaped arm 22 facing each other. The connecting fork arm 23 has a shape as follows: the connecting fork arm 23 includes a cross-arranged X-shaped fork arm portion, and four connecting portions located at the end corners are integrally formed on the fork arm portion, and the connecting portions are fixedly connected to the U-shaped arm 22.

[0049] At the same time, a cylinder 24 is installed on the connecting beam B, and the piston rod of the cylinder 24 is installed at the bottom of the connecting fork arm 23. Specifically, a driving connecting rod 241 is fixedly connected to the piston rod of the cylinder 24, and a blocking seat at the bottom of the connecting fork arm 23 is fixedly connected to the upper end of the driving connecting rod 241, and a locking nut for locking the connecting fork arm 23 is fixedly connected to the top of the driving connecting rod 241.

[0050] When installing the locking arm assembly, the U-shaped arm 22 is slid along the upper end of the driving connecting rod 241 and supported on the top of the baffle seat, and then the locking nut is locked to achieve the installation of the U-shaped arm 22.

[0051] The cylinder 24 is installed between adjacent connecting beams B. Specifically, cylinder plates for clamping the cylinder are respectively welded to the connecting beams B, and bolts for fastening the cylinder are installed on the cylinder plates.

[0052] At the same time, in order to realize the pressing processing and quickly and accurately release the shell workpiece 4 after processing, the fork arm part is equipped with a plurality of spring slide rods, and the spring slide rods are fixedly installed on the connecting beam B.

[0053] Specifically, the two spring slide rods at the front side and the two spring slide rods at the rear side are fixed on a connecting beam B respectively.

[0054] Specifically, the spring slide rod member includes a slide rod 25 slidably connected to the fork arm portion, a spring 251 is sleeved on the slide rod 25, and the two ends of the spring 251 are respectively fixedly connected to the bottom of the fork arm portion and the top of the connecting beam B; the upper end of the slide rod 25 is connected to an anti-slip baffle sleeve.

[0055] During the pressing process, the connecting fork arm 23-U-shaped arm 22-annular locking plate 21 is pressed down by the cylinder 24, and the spring 251 is compressed. During the release process of the housing workpiece 4, the elastic restoring force of the spring 251 is used to drive the fork arm-U-shaped arm 22-annular locking plate 21 to separate from the released workpiece, thereby realizing quick pressing and quick release of the workpiece.

[0056] Through the above-mentioned device, it is possible to simultaneously process multiple shell workpieces 4 with special-shaped structures, and during the processing, locking the workpiece is simple. The specific shape structure of the shell workpiece 4 is used in conjunction with the clamp to achieve upward pressure locking. This locking method can achieve sufficient locking and is not likely to cause shell deformation during the locking process. More significantly, the processing efficiency is high.

[0057] Example 2

[0058] like Figure 1-5 As shown, based on the structure of Example 1, in order to solve the problem of rapid material discharge after processing and the problem of debris entering the material hole during the discharge process, the above-mentioned shock-absorbing air bag automatic material return and chip removal tooling also includes a material discharge and chip removal mechanism installed below the loading tooling 1. After processing, the shock-absorbing air bag shell workpiece 4 is ejected through the material discharge and chip removal mechanism, and the debris is ejected at the same time.

[0059] Specifically, the material discharge and chip discharge mechanism includes a mouth-shaped base 3, and the top of the base 3 is assembled and connected with a plurality of top columns 31 corresponding to the material hole 11; the top column 31 is a solid structure, so in the process of loading the material into the material hole 11, on the one hand, the material is lifted and discharged, and on the other hand, the material hole 11 is sealed to prevent debris from falling in. At the same time, when the debris enters and falls into the material hole 11, the debris is pushed out of the material hole 11 during the process of pushing the top column 31 upward, thereby preventing the debris from affecting the cleanliness of the material hole 11. At the same time, the top column 31 that slides into the material hole 11 also plays a role in cleaning the material hole 11, and uses friction to discharge the debris on the wall of the material hole 11 and push it up to separate from the material hole 11. In this way, the shell can discharge materials accurately and smoothly during the subsequent loading of the shell, thereby improving the stability of the discharge.

[0060] Specifically, two lifting cylinders 24 spaced apart from each other are assembled and connected to the top of the base 3 , and the piston rods of the lifting cylinders 24 are installed at the bottom of the connecting beam B.

[0061] The top of the top column 31 is integrally formed with an annular flange, which is fastened to the top of the base 3 by bolts. In this way, the detachability is achieved.

[0062] At the same time, in order to improve the lifting stability, the base 3 is fixedly connected with a plurality of guide rods 33 slidably connected to the connecting beam B. During operation, driven by the lifting cylinder 24, the tooling carries the shell workpiece 4 down to the top column 31, slides into the material hole 11, pushes the workpiece and removes chips synchronously.

[0063] The transverse cross-section of the base 3 is in the shape of a mouth, and a plurality of mounting claws A are welded on the outer wall of the base 3. The mounting holes on the mounting claws A enable the entire device to be mounted on a workbench.

[0064] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
