Description

Technical Field

[0001] The utility model relates to the technical field related to machining centers, in particular to a blanking mechanism and a machining center thereof. Background Art

[0002] A machining center is a highly automated, multifunctional machine equipped with a tool magazine and automatic tool changer. A vertical machining center is one in which the spindle axis is perpendicular to the worktable and is primarily suitable for machining complex parts such as plates, discs, molds, and small housings.

[0003] When the machining center completes processing on the workpiece and unloads the workpiece, it needs to place the workpiece in a stable state. Since some workpieces are in an irregular state, the placement of the workpiece needs to be adjusted. Only after the processed workpiece is placed can the operator re-place the workpiece to be processed, resulting in a long time for unloading the workpiece, which is not conducive to the efficient production of the workpiece. In addition, some heavier workpieces are inconvenient for operators to take out and place from the machining center, which is not conducive to the rapid unloading of the workpiece and the efficient processing of the workpiece by the machining center.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The utility model provides Figure 1-4 The blanking mechanism shown in the figure comprises a support frame 1, a plurality of support frames 1 are provided with a blanking frame 2 at the top, and the shape of the blanking frame 2 is as follows: Figure 1 As shown, the unloading rack 2 can be pushed to the machining center through the universal wheels at the bottom of the support frame 1, and the top horizontal position of the unloading rack 2 can extend to the interior of the machining center;

[0035] Furthermore, a material unloading component 3 is provided on the material unloading rack 2, and the material unloading component 3 includes: a pulley 31, a pulley 32, a clamping component 33 and a buffer component 34. The pulley 31 is arranged at the top of the material unloading rack 2; a plurality of slide grooves are opened at the top of the material unloading rack 2, and a plurality of pulleys 32 are respectively arranged inside the plurality of slide grooves, and a plurality of pulleys 32 are respectively fixedly installed at the bottom corners of the pulley 31. The pulley 31 can slide on the material unloading rack 2 through the pulley 32, and transport the workpiece fixed by the clamping component 33 from the workbench of the machining center to the ground height; the clamping component 33 is arranged inside the pulley 31 for fixing the workpiece; the buffer component 34 is arranged on the material unloading rack 2, which can buffer the sliding pulley 31, so that the staff can unload more stably.

[0036] Specifically, the clamping assembly 33 includes: a driving rod 331, a slider 332 and a clamping plate 333. An adjustment groove is provided at the top end of the inner wall of the pulley 31, and both ends of the driving rod 331 are rotatably and interlacedly connected with the inner wall of the adjustment groove; a bidirectional thread is provided on the outer wall of the driving rod 331, and multiple sliders 332 form a screw transmission with the driving rod 331; multiple clamping plates 333 are all located inside the pulley 31, and multiple clamping plates 333 are respectively fixedly connected to multiple sliders 332. Through the rotation of the driving rod 331, the slider 332 can drive the clamping plates 333 to move horizontally away from or closer to each other in the horizontal direction inside the pulley 31, so that workpieces of different sizes can be clamped and fixed to facilitate subsequent blanking operations.

[0037] Furthermore, a rubber pad 4 is fixedly connected to the opposite side of each of the multiple clamping plates 333, and the outer wall of the rubber pad 4 is provided with an anti-slip texture. The provision of the rubber pad 4 increases the friction between the clamping plate 333 and the workpiece, so that even for special-shaped parts, the clamping stability can be guaranteed, and the workpiece is also protected to prevent the clamping plate 333 from clamping the outer wall of the workpiece.

[0038] Specifically, the buffer assembly 34 includes: a sleeve 341, a telescopic rod 342, a buffer plate 343, a first compression spring 344, a positioning block 345 and a second compression spring 346.

The first compression spring 344 is always in a compressed state, so that it can provide a stable elastic force to the buffer plate 343 through the telescopic rod 342, so that when the pulley 31 slides down, the momentum of the pulley 31 can be reduced. The cam 345 is pressed against the top of the cam 346 to release the cam 347 so that the cam 347 will move upwards and the cam 347 will move downwards to release the cam 347.

[0039] Furthermore, both sides of the positioning block 345 are fixedly connected with the limiting blocks 5, and the limiting grooves are opened on both sides of the inner wall of the positioning groove. The limiting blocks 5 are slidably connected with the inner cavity of the limiting groove. The limiting blocks 5 play a limiting role on the positioning block 345, so that the positioning block 345 can only be displaced in the vertical direction along the limiting groove.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
