Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing, specifically a welding and positioning fixture for an automotive chassis guard plate bracket. Background Technology

[0002] Welding of the chassis skid plate bracket is a key process to ensure the stable installation of the skid plate and to resist road impacts (such as stone impacts and bumps) and harsh environments (such as rainwater and mud corrosion). Before welding the chassis skid plate bracket, it needs to be positioned and fixed by positioning fixtures.

[0003] In existing technologies, chassis guard plate brackets are typically fixed using a single clamping mechanism, which can only fix a single type of guard plate bracket. This not only results in insufficient fixing stability, which can easily affect the stability of subsequent welding, but also makes it difficult to fix guard plate brackets of different sizes, thus lacking flexibility in use. Furthermore, welding the guard plate brackets generates dust and gas impurities, which, if not treated, can easily affect the surrounding air environment and the health of workers.

[0004] Therefore, a welding and positioning fixture for automotive chassis guard plate brackets is proposed to address the above problems. Utility Model Content

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The automotive chassis guard plate bracket welding positioning fixture of this utility model includes a base, positioning plates are slidably connected to both sides of the top of the base, exhaust fans are installed on both sides of the outer side of the base, a positioning component is provided on the top of the base, the positioning component includes a limiting block, sliding rods are symmetrically slidably connected to both sides of the top of the base, the top of the two sets of sliding rods are fixedly connected to the limiting block, and clamping plates are symmetrically slidably connected to the inner sides of the two positioning plates.

[0007] Preferably, a first bidirectional lead screw is rotatably connected inside the base, and a first motor is fixedly connected to the outer side of the base via a mounting plate. The output end of the first motor extends into the interior of the base and is fixedly connected to the first bidirectional lead screw. Slider blocks are connected to both outer sides of the first bidirectional lead screw via lead screw nut pairs, and the tops of the two sliders are respectively fixedly connected to corresponding positioning plates.

[0008] Preferably, the outer sides of the first bidirectional lead screw and the inner sides of the two sliders are connected to threaded rings through lead screw nut pairs, and the outer sides of the two threaded rings are rotatably connected to connecting rods, and the two sets of sliders are respectively rotatably connected to the top of the corresponding connecting rods.

A second motor is fixedly connected to the outer side of the positioning plate through a mounting plate, and the output end of the second motor extends into the interior of the positioning plate and is fixedly connected to the second bidirectional lead screw.

[0010] Preferably, a dust collection frame is fixedly connected to the top of each of the two exhaust fans, air inlets are equidistantly opened on both sides of the exterior of each exhaust fan, and a pull-out box is installed on the exterior of each of the two exhaust fans.

In addition, during the subsequent welding process, the dust and gas impurities generated can be sucked out by the exhaust fan in conjunction with the dust collection frame, avoiding the spread of dust and gas impurities and causing impact on the surrounding environment and the health of the workers. 2.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Please see Figure 1-4As shown, a welding and positioning fixture for an automotive chassis guard plate bracket includes a base 1. Positioning plates 4 are slidably connected to both sides of the top of the base 1. Exhaust fans 6 are installed on both sides of the outer surface of the base 1. A positioning assembly is provided on the top of the base 1, including limit blocks 3. Sliding rods 2 are symmetrically slidably connected to both sides of the top of the base 1. Limit blocks 3 are fixedly connected to the top of both sets of sliding rods 2. Clamping plates 5 are symmetrically slidably connected to the inner sides of the two positioning plates 4. A first bidirectional lead screw 8 is rotatably connected inside the base 1. A first motor 9 is fixedly connected to one side of the base 1 via a mounting plate. The output end of the first motor 9 extends into the interior of the base 1 and is fixedly connected to the first bidirectional lead screw 8. The first bidirectional lead screw 8 is connected to the outer sides of the base 1 via lead screw screws. The female and male parts are connected to sliders 12. The tops of the two sliders 12 are fixedly connected to the corresponding positioning plates 4. The outer sides of the first bidirectional lead screw 8 and the inner sides of the two sliders 12 are connected to threaded rings 10 through lead screw nut pairs. The outer sides of the two threaded rings 10 are rotatably connected to connecting rods 11. The two sets of slide rods 2 are rotatably connected to the tops of the corresponding connecting rods 11. The inner sides of the two positioning plates 4 are rotatably connected to second bidirectional lead screws 13. The two clamping plates 5 are connected to the outer sides of the corresponding second bidirectional lead screws 13 through lead screw nut pairs. The outer side of the positioning plate 4 is fixedly connected to a second motor 14 through a mounting plate. The output end of the second motor 14 extends into the interior of the positioning plate 4 and is fixedly connected to the second bidirectional lead screw 13.

[0019] During operation, the car chassis underbody bracket is placed on top of the base 1. Then, the first motor 9 is started to drive the first double-acting lead screw 8 to rotate. This causes the first double-acting lead screw 8 to drive the two threaded rings 10 to move to both sides through the lead screw nut pair, and also drives the two sliders 12 to move inward. As a result, the two threaded rings 10 drive the two sets of limiting blocks 3 to move inward through the connecting rod 11, until the two sets of limiting blocks 3 and the positioning plate 4 are centered and positioned on the chassis underbody bracket, providing a certain clamping force and improving the positioning stability of the chassis underbody bracket. Then, the second motor 14 is started to drive the second double-acting lead screw 8 to rotate. Rotating the lead screw 13 causes the second bidirectional lead screw 13 to drive the two clamping plates 5 to move inward through the lead screw nut pair. This locks and clamps the chassis guard plate bracket through the two sets of clamping plates 5, completing the stable installation of the chassis guard plate bracket. This further improves the positioning stability and welding stability of the chassis guard plate bracket. Then, the chassis guard plate bracket can be welded. The exhaust fan 6 is started, and the dust and gas impurities generated during the welding process can be sucked out by the dust suction frame 7, preventing the dust and gas impurities from spreading and affecting the surrounding environment and the health of the staff.

[0020] This device first uses two sets of limiting blocks 3 and positioning plates 4 to center and position the chassis guard plate bracket, providing a certain clamping force and improving the positioning stability of the chassis guard plate bracket. Then, two sets of clamping plates 5 are used to lock and clamp the two ends of the chassis guard plate bracket, completing the stable installation of the chassis guard plate bracket. This further improves the positioning stability and welding stability of the chassis guard plate bracket. In the subsequent welding process, the exhaust fan 6 and the dust collection frame 7 can be used to suck up the generated dust and gas impurities, preventing the dust and gas impurities from spreading and affecting the surrounding environment and the health of the staff.

[0021] The top of each of the two exhaust fans 6 is fixedly connected to a dust collection rack 7. Air inlets are equidistantly opened on both sides of the exterior of the exhaust fans 6. Pull-out boxes are installed on the exterior of each of the two exhaust fans 6. A first anti-slip pad 15 is fixedly connected to the top of the base 1 and between the two sets of limit blocks 3 and the positioning plate 4. The first motor 9 and the second motor 14 are both electrically connected to an external controller.

[0022] With the above technical solution, the collected dust can be centrally processed by pulling out the pull-out box. The first anti-slip pad 15 increases the friction between the pad and the chassis guard plate bracket, thereby further improving the stability of the chassis guard plate bracket. The first motor 9 and the second motor 14 can be quickly controlled by the staff through the external controller.

[0023] Example 2 Please see Figure 4 As shown in the first embodiment, as another implementation of this utility model, the inner sides of both sets of clamping plates 5 are fixedly connected with second anti-slip pads 16, and both sets of second anti-slip pads 16 are made of rubber material.

[0024] During operation, the second anti-slip pad 16 made of rubber material can increase the friction between the chassis guard plate bracket and the clamping plate 5, thereby further improving the clamping stability of the chassis guard plate bracket and ensuring the stability of the subsequent welding process.
