Description

Technical Field

[0001] This utility model relates to the field of muffler welding technology, and more specifically, to a positioning auxiliary device for muffler welding. Background Technology

[0002] With the rapid development of society and economy, cars have gradually entered thousands of households. However, with the increase in the number of cars owned by Chinese residents, the noise generated by car intake and exhaust has gradually become one of the main sources of environmental noise in cities. Therefore, exhaust mufflers are installed at the rear of the engine during the car production process to effectively limit exhaust noise pollution. During the production of the muffler, it is necessary to use a positioning auxiliary device to clamp and fix the muffler for welding.

[0003] For example, CN218362989U discloses a positioning auxiliary device for welding automotive mufflers. The key technical points of this device are: it includes a base plate, two mounting plates fixedly mounted on the upper surface of the base plate, several sliding rods fixedly mounted between the opposing surfaces of the two mounting plates, two movable blocks slidably mounted on the outer surfaces of the sliding rods, and a fixed block fixedly mounted on the outer surfaces of the sliding rods and located between the two movable blocks. The upper surface of each movable block is provided with a clamping assembly for clamping mufflers of different sizes. A rotating shaft is rotatably mounted on the fixed block, and a rotating rod is fixedly mounted at the end of the rotating shaft. Several springs are fixedly mounted between the opposing surfaces of the movable block and the fixed block. Both ends of the rotating rod are rotatably connected to hinge rods, and the other end of each hinge rod is rotatably connected to a movable block. One of the mounting plates is threaded. A threaded rod is installed, with a sleeve fitted at one end and the other end of the sleeve fixedly connected to a movable block on the same side. The other end of the threaded rod extends to the outside of the mounting plate and is fixed with a handwheel. The system mainly consists of a threaded rod, a sleeve, a movable block, a fixed block, and a clamping block. Rotating the handwheel drives the threaded rod to rotate, which in turn drives one of the movable blocks through the sleeve. This movement of the movable block drives a rotating rod through a hinge rod, which in turn drives another movable block through another hinge rod. Simultaneously, the movement of the movable blocks causes the clamping block to follow suit. This allows the two movable blocks and the clamping block on each other to move closer together and, in conjunction with a spring, clamp and fix the car muffler when the handwheel is rotated. This system is suitable for clamping and fixing car mufflers of different models and sizes, and has a wide range of applications.

[0004] The aforementioned positioning auxiliary device for welding automotive mufflers still has some shortcomings: since the muffler is fixed by the positioning auxiliary device, if the welding direction needs to be changed, the change in the position of the muffler will increase the workload of the workers and also increase the welding time. Therefore, it is necessary to provide a positioning auxiliary device for welding mufflers. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide a positioning auxiliary device for welding mufflers. By setting a connecting groove and a connecting rod, when maintenance of the internal parts of the direction adjustment component is required, the protective shell is lifted upwards until the connecting rod is pulled out from the inside of the connecting groove, at which point the direction adjustment component can be disassembled. Because the connecting rod is snapped into the inside of the connecting groove, compared with other connection methods to connect the protective shell and the base, this connection method saves more time during disassembly, thus solving the problems existing in the prior art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a positioning auxiliary device for welding a muffler, comprising a welding base, wherein a direction adjustment component is detachably installed on the top of the welding base, and a positioning auxiliary component is fixedly connected to the top of the direction adjustment component;

[0007] The positioning auxiliary component includes a stabilizing base, an auxiliary block is fixedly connected to the middle of the top of the stabilizing base, and multiple positioning rings are fixedly connected to the top of the stabilizing base in a rectangular array. Two second hydraulic telescopic rods are detachably installed symmetrically around the center inside the positioning rings.

[0008] One end of the second hydraulic telescopic rod is fixedly connected to an arc-shaped connecting plate, and an arc-shaped protective pad is adhered to the side wall of the arc-shaped connecting plate.

[0009] The orientation adjustment component includes a base, the top of which has multiple connecting slots arranged in a rectangular array, and a stabilizing plate is fixedly connected to one side of the top of the base.

[0010] The first hydraulic telescopic rod is detachably installed at the top of the side wall of the stabilizing plate, and a gear rack is fixedly connected to one end of the first hydraulic telescopic rod.

[0011] The base has a first bearing embedded in the middle of its upper surface, a drive shaft fixedly sleeved inside the first bearing, a spur gear fixedly sleeved in the middle of the drive shaft surface, the surface of the spur gear meshing with the side wall of the gear rack, and the top of the drive shaft connected to the center of the lower surface of the stabilizing seat.

[0012] The base has a protective shell connected to its top end via the connecting groove, and the bottom end of the protective shell is fixedly connected to multiple connecting rods in a rectangular array. The surface of the connecting rods is adapted to the interior of the connecting groove.

[0013] The protective shell has a second bearing embedded in the middle of its top end, and the interior of the second bearing is in contact with the top end of the drive shaft surface.

[0014] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0015] 1. In the above solution, the positioning auxiliary device is equipped with a direction adjustment component. When it is necessary to change the welding direction of the muffler, the first hydraulic telescopic rod inside the direction adjustment component is activated, which drives the gear rack to move. Because the side wall of the gear rack meshes with the surface of the spur gear, and the spur gear is connected to the base through the drive shaft and the first bearing, the movement of the gear rack can drive the drive shaft to rotate. Since the muffler is connected to the drive shaft through the positioning auxiliary component, the rotation of the drive shaft can drive the muffler to rotate until the muffler is adjusted to the ideal direction. Since the first hydraulic telescopic rod has an automatic extension and retraction function, it can replace the workers in adjusting the welding direction of the muffler, thereby reducing the workload of the workers.

[0016] 2. In the above solution, the positioning auxiliary device is equipped with a connecting groove and a connecting rod. When it is necessary to maintain the internal parts of the direction adjustment component, the protective shell is lifted upwards until the connecting rod is pulled out from the inside of the connecting groove. At this time, the direction adjustment component can be disassembled. Because the connecting rod is snapped into the inside of the connecting groove, compared with other connection methods to connect the protective shell and the base, this connection method saves more time during disassembly.

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1:

[0025] Please see Figure 1-4 A positioning auxiliary device for welding a muffler includes a welding base 1, a direction adjustment component 2 is detachably installed on the top of the welding base 1, and a positioning auxiliary component 3 is fixedly connected to the top of the direction adjustment component 2.

[0026] The positioning auxiliary component 3 includes a stabilizing base 31, an auxiliary block 32 is fixedly connected to the middle of the top of the stabilizing base 31, and multiple positioning rings 33 are fixedly connected to the top of the stabilizing base 31 in a rectangular array. Two second hydraulic telescopic rods 34 are detachably installed symmetrically along the center inside the positioning rings 33.

[0027] One end of the second hydraulic telescopic rod 34 is fixedly connected to an arc-shaped connecting plate 35. An arc-shaped protective pad 36 is adhered to the side wall of the arc-shaped connecting plate 35. The direction adjustment assembly 2 includes a base 21. The top of the base 21 has multiple connecting slots 22 arranged in a rectangular array. A stabilizing plate 23 is fixedly connected to one side of the top of the base 21. The top of the side wall of the stabilizing plate 23 is detachably mounted with a first hydraulic telescopic rod 24. One end of the first hydraulic telescopic rod 24 is fixedly connected to a gear rack 25. A first bearing 26 is embedded in the middle of the upper surface of the base 21. A drive is fixedly sleeved inside the first bearing 26. A spur gear 28 is fixedly sleeved on the middle of the surface of the drive shaft 27. The surface of the spur gear 28 meshes with the side wall of the gear rack 25. The top of the drive shaft 27 is connected to the center of the lower surface of the stabilizer 31. The top of the base 21 is connected to a protective shell 29 through a connecting groove 22. Multiple connecting rods 210 are fixedly connected to the bottom of the protective shell 29 in a rectangular array. The surface of the connecting rods 210 is adapted to the inside of the connecting groove 22. A second bearing 211 is inlaid and installed in the middle of the top of the protective shell 29. The inside of the second bearing 211 is in contact with the top of the surface of the drive shaft 27.

[0028] Benefits: The auxiliary block 32 facilitates the welding of the muffler, thereby enhancing the practicality of the device.

[0029] The working process of this utility model is as follows:

[0030] In order to reduce the workload of the workers, the positioning auxiliary device is equipped with a direction adjustment component 2. When it is necessary to change the welding direction of the muffler, the first hydraulic telescopic rod 24 inside the direction adjustment component 2 is activated, which drives the gear rack 25 to move. Because the side wall of the gear rack 25 meshes with the surface of the spur gear 28, and the spur gear 28 is connected to the base 21 through the drive shaft 27 and the first bearing 26, the movement of the gear rack 25 can drive the drive shaft 27 to rotate. Since the muffler is connected to the drive shaft 27 through the positioning auxiliary component 3, the rotation of the drive shaft 27 can drive the muffler to rotate until the muffler is adjusted to the ideal direction. Since the first hydraulic telescopic rod 24 has an automatic extension and retraction function, it can replace the workers in adjusting the welding direction of the muffler, thereby reducing the workload of the workers.

[0031] In the above scheme, the positioning auxiliary device is equipped with a connecting groove 22 and a connecting rod 210 to facilitate the maintenance of the direction adjustment component 2. When it is necessary to maintain the internal parts of the direction adjustment component 2, the protective shell 29 is lifted upwards until the connecting rod 210 is pulled out from the inside of the connecting groove 22. At this time, the direction adjustment component 2 can be disassembled. Because the connecting rod 210 is snapped into the inside of the connecting groove 22, compared with other connection methods to connect the protective shell 29 and the base 21, this connection method saves more time during disassembly.
