Description

Technical Field

[0001] The utility model relates to the technical field of muffler processing, in particular to a muffler welding fixture. Background Art

[0002] A silencer is a noise reduction device that can be used in air flow ducts that also transmit noise. It can use pipes and elbows with sound-absorbing linings, or pipes with sudden changes in cross-sectional area and other discontinuous acoustic impedance to attenuate or reflect the noise in the duct. The former is called a resistive silencer, and the latter is called a reactive silencer. There are also impedance composite silencers. The silencer needs to be clamped and fixed by a welding fixture for welding during production.

[0003] When clamping and fixing the silencer pipe, if a traditional small clamp is used to fix it with bolts, it is easy to cause the clamp and the silencer pipe to consume a lot of time during the fixing and disassembly process, thereby reducing the subsequent welding efficiency. In addition, some small clamps can only clamp silencer pipes of a single size, which is not only not practical, but also has general clamping stability, which is not conducive to improving the welding accuracy of the silencer pipe.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1-4 A muffler welding fixture shown includes a workbench 1, the top of which is provided with two movable positioning seats, the positioning seats are provided with a fixing seat 4, and the fixing seat 4 is provided with a clamping mechanism;

[0024] The clamping mechanism includes a driving component, on which a plurality of connecting rods 8 are hinged, and a free end of the connecting rod 8 is hinged with an arc-shaped clamping piece 7, and a plurality of guide holes 401 are opened on the fixing seat 4, and the clamping piece 7 is slidably connected in the guide holes 401;

[0025] In this embodiment, there are four clamping pieces 7, which can clamp the silencer pipe in multiple directions, thus providing higher stability.

[0026] During specific use, the silencer pipe is first clamped by the clamping sheet 7, and then the positioning seat is moved to make the two silencer pipes abut against each other, and then welding is performed to improve the welding accuracy.

[0027] If the positioning seat is moved first, there will be two clamping plates 7 at this time, which are distributed front and back. After the positioning seat is moved to the appropriate position, the silencer pipe is placed between the two clamping plates 7 from top to bottom to clamp the silencer pipe. The same is true for the other one. One end of the silencer pipe is abutted against the fixed seat 4, and the other ends are abutted against each other, and then welding can be performed.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, a supporting unit is also provided on the workbench 1, and a plug-in unit for fixing the positioning seat is provided on the supporting unit.

[0029] like Figure 1 and Figure 3 As shown, the positioning seat includes an L-shaped support plate 10, and two positioning holes 1001 are formed on the horizontal support plate of the support plate 10.

[0030] like Figure 1 and Figure 2 As shown, the driving component includes a driving motor 2 arranged on a vertical support plate 10, the output end of the driving motor 2 is fixedly connected to a screw rod 14, the free end of the screw rod 14 is rotatably connected to a fixed seat 4, the outer ring of the screw rod 14 is threadedly connected to a solenoid 3, and a connecting rod 8 is hinged on the side wall of the solenoid 3.

[0031] When clamping the silencer pipe fittings, the lead screw 14 is rotated by driving the motor 2, and then the clamping piece 7 moves in the guide hole 401 through the screw tube 3 in cooperation with the connecting rod 8. Within a certain range, silencer pipe fittings of different sizes can be clamped.

[0032] like Figure 3 and Figure 4 As shown, the supporting unit includes a supporting plate 6, two ends of the supporting plate 6 are fixedly connected to two support rods 9, the support rods 9 are provided with a plurality of adjustment holes 901, and the support plate 10 is slidably sleeved on the outer ring of the support rods 9;

[0033] Two symmetrically distributed side panels 101 are fixedly connected to the top of the workbench 1 , and the free ends of the support rods 9 are fixedly connected to the side panels 101 .

[0034] In a specific implementation, the bottom of the fixing seat 4 is slidably connected to the top of the supporting plate 6, so that when the supporting plate 10 moves, the fixing seat 4 moves stably accordingly. Therefore, in this embodiment, the bottom of the supporting plate 10 is slidably connected to the top of the workbench 1.

[0035] like Figure 3 and Figure 4 As shown, two buffer rods 12 are slidably sleeved on the supporting plate 6, the top end of the buffer rod 12 is fixedly connected to an arc-shaped bracket 5, the bottom end of the buffer rod 12 is fixedly connected to a gasket 1201, and a buffer spring 13 sleeved on the outer ring of the buffer rod 12 is fixedly connected between the bracket 5 and the supporting plate 6.

[0036] When the silencer pipe is placed, the buffer spring 13 absorbs the falling impact caused by the gravity of the silencer pipe.

[0037] like Figure 3 As shown, the plug-in is a U-shaped plug rod 11. When the support plate 10 is moved to a suitable position, the plug rod 11 is inserted into the corresponding adjustment hole 901 and then inserted into the positioning hole 1001 to limit the support plate 10.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
