Description

Technical Field

[0001] The utility model relates to a milling machine auxiliary device, in particular to an automatic positioning and clamping device for ear plates used for fine machining of a milling machine. Background Art

[0002] In today's machining industry, milling machines, as an important metal cutting equipment, are widely used to process a variety of complex parts, including parts with specific shape and size requirements such as lugs. However, when using traditional milling machines to perform precision machining of lugs, the design of the fixtures is often cumbersome and inefficient, which is mainly reflected in the following aspects:

[0003] Existing fixtures typically rely on a complex system of multiple clamps, precisely mounted on the milling machine's worktable using bolts and other fasteners to fully clamp the lugs on all sides. While this design ensures the lugs' stability during machining, it also presents the problem of extremely cumbersome installation and removal of the clamps. Operators must individually adjust the position of each clamp and use tools to tighten or loosen numerous bolts, a time-consuming and labor-intensive process that increases the risk of operator error and impacts overall machining efficiency. Utility Model Content

[0004] In order to overcome the disadvantage that when a milling machine processes ear plates, the fixing fixture is inconvenient to install and remove, which greatly reduces the processing efficiency, the utility model provides an automatic positioning and clamping device for ear plates used in fine processing of a milling machine.

[0005] The technical solution is: an automatic positioning and clamping device for ear plates used for fine processing of milling machines, including a milling machine and a placement plate. A placement plate is provided in the middle of the milling machine, and the placement plate is located below the milling cutter of the milling machine. It also includes a cylinder, a push plate, an extrusion plate, a fixed plate and a positioning plate. The cylinder is fixed in the milling machine, and the telescopic end of the cylinder is connected to the push plate. A slide rail is provided in the middle of the push plate, and the extrusion plate is slidably connected to the slide rail. A return spring is provided in the slide rail, and both ends of the return spring are respectively connected to the extrusion plate and the push plate. The fixed plate is fixed to the placement plate, and the positioning plate slides vertically on the fixed plate.

[0006] Furthermore, it also includes a synchronization component, which includes an inclined plate, a gear and a rack. The inclined plate is slidably connected to the placement plate, the extrusion plate can contact the inclined plate, and the gear is rotatably connected to the middle of the placement plate through a rotating shaft. The inclined plate and the positioning plate are both fixed with a rack engaged with the gear.

[0007] Furthermore, a maintenance hole is opened on the placement plate, and the maintenance hole corresponds to the gear position.

[0008] Furthermore, a locking block is included. A limiting hole is provided on the fixing plate. The locking block is slidably connected to the positioning plate. The locking block can be inserted into the limiting hole to fix the positioning plate.

[0009] Furthermore, a foam pad is included, and the opposite sides of the extrusion plate and the positioning plate are both provided with foam pads.

[0010] Furthermore, it also includes a universal ball, and the universal ball is arranged on the surface of the placement plate.

[0011] Furthermore, a scale is also included. The placement plate is provided with a scale, and the scale marks the position of the positioning plate.

[0012] The beneficial effects of the present invention are as follows: the ear plate is positioned and placed by the right-angle part composed of the fixing plate and the positioning plate, and then the cylinder is turned on to drive the push plate to move backward, and the inclined plate pushes the extrusion plate to move to the left, and the extrusion plate will cooperate with the positioning plate to clamp and fix the ear plate. The ear plate is conveniently clamped and fixed by the opposite clamping method, which is simpler than the previous method of repeatedly installing and removing bolts.

The fixed plate 8 is fixed to the placement plate 2, and the positioning plate 9 slides vertically on the fixed plate 8.

[0020] like Figure 3 As shown, it also includes a synchronization component, which includes an inclined plate 7, a gear 10 and a rack 12. The inclined plate 7 is slidably connected to the placement plate 2, and the extrusion plate 5 can contact the inclined plate 7. The gear 10 is rotatably connected to the middle of the placement plate 2 through the rotating shaft 11. The inclined plate 7 and the positioning plate 9 are both fixed with a rack 12 engaged with the gear 10. A maintenance hole 16 is provided on the placement plate 2, and the maintenance hole 16 corresponds to the corresponding position of the rotating shaft 11. The rotating shaft 11 is provided with an inner hexagon, so when the staff needs to rotate the gear 10, they can use a specific tool to rotate the rotating shaft 11.
