Description

Technical Field

[0001] The utility model relates to the field of muffler bag processing equipment, and more specifically, to a clamping unit of a muffler bag. Background Art

[0002] When processing the silencer cover plate, it is necessary to perform a drilling process. During the drilling process, the general drilling equipment is not firm enough to position the cover plate, so that the cover plate moves when the holes are punched, thus affecting the drilling accuracy. Usually, when punching holes in the cover plate, workers are required to place the cover plate in the positioning groove of the processing table for positioning. After the drilling is completed, the cover plate is taken out of the positioning groove and placed in the frame.

[0003] For example, the authorization announcement number CN216913607U discloses a clamping device for assembling a silencer bag, which includes a workbench, a clamping assembly placed on the workbench, and a material tray. The clamping assembly includes a machine, a clamp, and cylinders placed on both sides of the clamp. The clamp includes a mold frame and blocks placed on both sides of the mold frame. A work station for placing the silencer bag is formed between the mold frame and the block. An opening is provided on the block for the output end of the cylinder to pass through. A foot pedal associated with the two cylinders is provided under the workbench to drive the cylinder to control its output end to extend into the work station to squeeze the silencer bag.

[0004] In the above, the cylinder controls the top plate to squeeze the silencer bag left and right. During the squeezing process, since there is no limiting structure for the silencer bag on the top plate, the silencer bag may deviate upward or downward, resulting in insufficient clamping force on the silencer bag cover. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a clamping unit for a silencer bag which improves the clamping of a silencer bag cover plate and prevents the silencer bag from deflecting upward or downward.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A clamping unit for a silencer bag comprises two pushing cylinders, which are symmetrically placed and have storage space for placing the silencer bag. A connecting pipe is provided on the output end of the pushing cylinder, and a first movable pipe and a second movable pipe are provided on the connecting pipe. The first movable pipe and the second movable pipe are both detachably connected to the connecting pipe. The length of the first movable pipe is greater than the length of the second movable pipe. A first fixed base plate is provided on the first movable pipe, which is fixedly connected to the first movable pipe. An upper clamping ramp and a lower clamping ramp are provided on the first fixed base plate. The upper clamping ramp is inclined from one side of the first fixed base plate toward the storage space, and the lower clamping ramp is inclined from the other side of the first fixed base plate toward the storage space. The upper clamping ramp and the lower clamping ramp are both fixedly connected to the first fixed base plate. A first limit block is provided on the upper clamping ramp and the lower clamping ramp, and the first limit block is fixedly connected to the upper clamping ramp and the lower clamping ramp.

[0008] The utility model is further configured as follows: there are two first limit blocks, a plurality of transversely distributed slots are opened on the first limit blocks, and the first limit blocks are made of silica gel.

[0009] The utility model is further configured as follows: a plurality of transversely distributed snap-in strips 1 are arranged in the first fixed base plate, and the snap-in strips 1 are made of silicone.

[0010] The utility model is further configured as follows: an external thread is provided on the outer wall of the connecting pipe, a pre-buried hole for the connecting pipe to extend into is opened in the first movable pipe, and a first internal thread spirally connected to the external thread is provided on the inner wall of the pre-buried hole.

[0011] By adopting the above technical solution, the beneficial effects of the utility model are:

[0012] First, place the silencer bag in the storage space, put the embedded hole on the first movable tube on the outer wall of the connecting tube, rotate the first movable tube, and spirally fix the first internal thread and the external thread to fix the first movable tube and the connecting tube. The two pushing cylinders push the first fixed base plate, and the first fixed base plates on the two pushing cylinders clamp the silencer bag. When the silencer bag deviates upward or downward, the upper clamping ramp and the lower clamping ramp can lock the silencer bag, thereby improving the clamping of the silencer bag cover and preventing the silencer bag from deviating upward or downward.

[0019] like Figures 1 to 3 As shown, the clamping unit of the silencer bag includes two pushing cylinders 1, which are symmetrically placed. The two pushing cylinders 1 have storage space, and the silencer bag can be placed in the storage space. The two pushing cylinders 1 clamp the silencer bag.

[0020] A connecting pipe 2 is installed on the output end of the pushing cylinder 1, and a first movable pipe 3 and a second movable pipe 13 are installed on the connecting pipe 2. An external thread 10 is installed on the outer wall of the connecting pipe 2. A pre-buried hole 11 for the connecting pipe 2 to extend into is opened in the first movable pipe 3, and a first internal thread 12 spirally connected to the external thread 10 is installed on the inner wall of the pre-buried hole 11, so that the connecting pipe 2 and the first movable pipe 3 are spirally fixed.

[0021] When the first movable tube 3 is removed from the connecting tube 2 , the first movable tube 3 is rotated, the first internal thread 12 and the external thread 10 are spirally turned out, and the first fixed base plate 4 is installed on the first movable tube 3 , and the first fixed base plate 4 and the first movable tube 3 are integrally formed.

[0023] The upper clamping ramp 5 and the lower clamping ramp 166 are both installed with the first limit blocks 7, which are integrally formed with the upper clamping ramp 5 and the lower clamping ramp 166. There are two first limit blocks 7, and four transversely distributed slots 8 are opened on the first limit blocks 7. The first limit blocks 7 are made of silicone. Eight transversely distributed clamping strips 9 are installed in the first fixed base plate 4, and the clamping strips 9 are made of silicone.

Both the upper pressing ramp 15 and the lower pressing ramp are fixedly connected to the second fixed base plate 14. The length of the first fixed base plate 4 is greater than that of the second fixed base plate 14. Therefore, according to the size of the silencer bag, it can be selected whether the first movable tube 3 is spirally fixed to the connecting tube 2 or the second movable tube 13 is spirally fixed to the connecting tube 2.
