Description

Technical Field

[0001] The utility model relates to the technical field of excavator component fixtures, in particular to a fixture used for excavator gear production. Background Art

[0002] An excavator, also known as an excavating machine or backhoe, is an earth-moving machine that uses a bucket to dig up materials above or below the surface and load them onto transport vehicles or unload them into a stockpile. Excavators primarily dig soil, coal, silt, and pre-loosened soil and rock. The production and processing of an excavator requires gears, an engine, a hydraulic pump, a distribution valve, a center slewing system, a slewing bearing, a travel drive, a cab, control valves, a relief valve, and a main control multi-way valve.

[0003] A fixture is a device used in the mechanical manufacturing process to secure the workpiece in the correct position for construction or testing. Broadly speaking, any device used to quickly, conveniently, and safely mount a workpiece during any process can be called a fixture. Examples include welding fixtures, gear hobbing fixtures, assembly fixtures, and machine tool fixtures. Machine tool fixtures are the most common, often referred to simply as fixtures. When machining a workpiece on a machine tool, the workpiece must be properly mounted and clamped before machining to ensure that the workpiece surface meets the technical requirements of the drawing, including dimensions, geometry, and relative positional accuracy with other surfaces. However, existing fixtures used in gear production struggle to quickly locate and secure the gear's center during clamping. Therefore, we propose a fixture for excavator gear production.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0027] The present invention will be described in further detail below in conjunction with the full text.

[0028] Combined with attachment Figures 1-4 A clamp for producing excavator gears includes a base 1, multiple groups of clamping arms 2 are hinged on the outside of the base 1, a power device 3 for pushing the clamping arms 2 to clamp the gear is installed inside the base 1, and the clamping arms 2 are set in at least three groups. The power device 3 drives the clamping arms 2 to rotate and fine-tune at the hinge point, thereby clamping the gear. Compared with traditional fixing methods, it is simpler and more convenient.

[0029] When the utility model is implemented, Figure 1-Figure 3As shown, the power device 3 includes a guide rod 301 slidably connected to the base 1, and the base 1 is equipped with an adjustable first block 302 and a second block 303. The two ends of the first block 302 and the second block 303 are respectively located between the guide rod 301 and the clamping arm 2. The guide rod 301 drives the first block 302 and the second block 303 to rotate and fine-tune the clamping gear of the hinged clamping arm 2. A movable groove 305 and a movable groove 306 are provided in the base 1 to cooperate with the movement of the first block 302 and the second block 303. A guide groove 307 used to cooperate with the guide rod 301 is provided in the base 1. A waist hole 304 is provided on the first block 302. A limiting shaft 5 is installed in the movable groove 305 and the limiting shaft 5 passes through the waist hole 304. The outer side of the guide rod 301 is provided The first adjustment slot 6 and the second adjustment slot 7 are used in conjunction with the first block 302 and the second block 303. Specifically, the guide rod 301 moves up and down, and the first adjustment slot 6 and the second adjustment slot 7 can push the first block 302 and the second block 303 to move in the movable slot 305 and the movable slot 306. The first block 302 and the second block 303 are respectively located at the upper and lower ends of the hinge point of the clamping arm 2. The second adjustment slot 7 becomes deeper as it goes downward, so that when the guide rod 301 moves downward, the second block 303 can be pushed against the lower part of the clamping arm 2 outward, thereby making the upper part of the clamping arm 2 inward to clamp the gear. Conversely, the guide rod 301 moves upward, moving the first block 302 to push the clamping arm 2, thereby driving the second block 303 to reset.

[0030] When the utility model is implemented, Figure 1 and Figure 2 As shown, the lower end of the power device 3 is equipped with an adjustment locking device 4 for adjusting the power device 3. Multiple groups of support legs 8 are installed under the base 1, and a limit plate 9 is installed between the multiple groups of support legs 8. The adjustment locking device 4 includes an adjustment spring 401 connected to the lower end of the guide rod 301. The lower end of the adjustment spring 401 is equipped with a baffle 402. The baffle 402 has a through hole in the middle, and the limit plate 9 has a threaded hole in the middle. An adjustment bolt 403 is installed in the threaded hole and extends through the through hole. One end of the adjustment bolt 403 is equipped with a limit plate 404. The adjustment bolt 403 rotates and moves in the threaded hole of the limit plate 9, driving the baffle 402 to move through the limit plate 404, pulling the guide rod 301 downward through the adjustment spring 401. By adjusting the pressure of the adjustment spring 401, the position of the guide rod 301 is changed, thereby changing the clamping method of the clamping arm 2.

[0031] Specifically, the blocking piece 402, the adjusting spring 401, the guide rod 301 and the threaded hole are coaxially arranged.

[0032] The working principle of this utility model:

[0033] like Figure 4As shown, the gear is placed on the base 1, and the guide rod 301 is pulled downward by adjusting the spring 401. By adjusting the pressure of the adjusting spring 401, the position of the guide rod 301 is changed. The guide rod 301 moves downward, and the second block 303 can be pushed outward against the lower part of the clamping arm 2, so that the upper part of the clamping arm 2 is turned inward, clamping the gear and quickly locating the center of the gear to be processed.

[0034] The above description of the present invention and its embodiments is non-limiting. What is shown in the full text is only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to the technical solution without creatively designing, they shall fall within the scope of protection of the present invention.
