Technical Field

[0001] The utility model relates to the technical field of welding tooling, in particular to a welding tooling for an excavator chain guard frame. Background Art

[0002] The excavator chain guard is a kind of engineering machinery accessory. During the production process, the chain guard needs to weld the required parts together to form a complete chain guard. During the welding, the required parts need to be positioned and fixed to prevent the parts from shaking during welding. For this reason, we propose an excavator chain guard welding tool to better help workers perform welding operations. Utility Model Content

[0003] The utility model provides a welding tool for an excavator chain guard frame, which prevents two chain guard frame arc plates from shaking during welding, thereby better helping workers to perform welding operations.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A welding tool for an excavator chain guard frame includes a base plate, positioning rods are fixed to the four corners of the top outer wall of the base plate, two vertical plates are fixed to the top outer wall of the base plate, the same long plate is placed on the top of the two vertical plates, a sliding groove is opened on the bottom outer wall of the long plate, a two-way threaded rod is inserted into the outer wall of one side of the long plate through a bearing, sliders are screwed to both ends of the two-way threaded rod, and splints are fixed to the bottom outer walls of the two sliders.

[0006] Through the above scheme, the two chain guard frame side plates can be placed on both sides of the long plate respectively, and the two bolt holes on the chain guard frame side plates can be correspondingly stuck on the positioning rod. At this time, the two chain guard frame arc plates can be placed on both ends of the chain guard frame side plates respectively, and the two chain guard frame arc plates can be leaned against the two vertical plates respectively. The two-way threaded rod is then rotated to make the two sliders approach each other, thereby driving the two clamping plates to approach each other. The two chain guard frame arc plates are respectively pressed against the two vertical plates through the two clamping plates, so that the chain guard frame arc plates are close to the vertical plates, preventing the two chain guard frame arc plates from shaking during welding, and better helping workers to perform welding operations.

[0007] Preferably, the thread directions of the two ends of the bidirectional threaded rod are opposite.

[0008] Through the above solution, the two sliders can move relative to each other when the bidirectional threaded rod rotates.

[0009] Preferably, fixing holes are provided at the four corners of the outer wall at the top of the bottom plate.

[0010] The above solution makes it easy to fix the base plate.

[0011] Preferably, a rotating handle is fixed to one end of the bidirectional threaded rod.

[0012] Through the above solution, it is convenient to rotate the bidirectional threaded rod.

[0013] Preferably, the two sliders are respectively slidably connected to the two ends of the inner wall of the slide groove, and threaded through holes are opened on the outer walls of one side of the two sliders. The two sliders are respectively screwed to the two ends of the bidirectional threaded rod.

[0014] Through the above solution, the two sliders can be screwed to the two ends of the bidirectional threaded rod.

[0015] Preferably, a through hole is opened on the outer wall of one side of the long plate, a bearing is fixed on the inner wall of the through hole, and a bidirectional threaded rod is fixed on the inner wall of the bearing.

[0016] Through the above solution, the plug-in installation of the bidirectional threaded rod is completed.

[0017] The beneficial effects of the utility model are:

[0018] The two chain guard frame side plates can be placed on both sides of the long plate respectively, and the two bolt holes on the chain guard frame side plates can be correspondingly stuck on the positioning rod. At this time, the two chain guard frame arc plates can be placed on both ends of the chain guard frame side plates respectively, and the two chain guard frame arc plates can be leaned against the two vertical plates respectively. The two-way threaded rod is then rotated to make the two sliders approach each other, thereby driving the two splints to approach each other, and the two chain guard frame arc plates are respectively pressed against the two vertical plates through the two splints, so that the chain guard frame arc plates are close to the vertical plates, thereby preventing the two chain guard frame arc plates from shaking during welding, and better helping workers to perform welding operations.

A bidirectional threaded rod 6 is connected to the outer wall of one side of the long plate 4 through a bearing. The threads at both ends of the bidirectional threaded rod 6 are in opposite directions. When the bidirectional threaded rod 6 rotates, the two sliders 7 can move relative to each other. A rotating handle 9 is fixed to one end of the bidirectional threaded rod 6 to facilitate the rotation of the bidirectional threaded rod 6.

[0026] Both ends of the two-way threaded rod 6 are screwed with sliders 7, and the outer walls of the bottoms of the two sliders 7 are fixed with plywood 8. The two chain guard frame side plates 11 can be placed on both sides of the long plate 4 respectively, and the two bolt holes on the chain guard frame side plates 11 are correspondingly stuck on the positioning rod 2. At this time, the two chain guard frame arc plates 12 can be placed on both ends of the chain guard frame side plates 11 respectively, and the two chain guard frame arc plates 12 are respectively leaned against the two vertical plates 3, and then the two-way threaded rod 6 is rotated to make the two sliders 7 approach each other, and then drive the two plywood 8 approach each other, and use the two plywood 8 to push the two chain guard frame arc plates 12 against the two vertical plates 3 respectively, so that the chain guard frame arc plates 12 are close to the vertical plates 3, preventing the two chain guard frame arc plates 12 from shaking during welding, and better helping workers perform welding operations.

[0027] Working principle: The two chain guard frame side plates 11 can be placed on both sides of the long plate 4 respectively, and the two bolt holes on the chain guard frame side plates 11 can be correspondingly stuck on the positioning rod 2. At this time, the two chain guard frame arc plates 12 can be placed on both ends of the chain guard frame side plates 11 respectively, and the two chain guard frame arc plates 12 can be respectively placed on the two vertical plates 3. Then, the two-way threaded rod 6 is rotated to make the two sliders 7 approach each other, and then drive the two splints 8 approach each other. The two chain guard frame arc plates 12 are respectively pressed against the two vertical plates 3 through the two splints 8, so that the chain guard frame arc plates 12 are close to the vertical plates 3, preventing the two chain guard frame arc plates 12 from shaking during welding, and better helping workers to perform welding operations.
