Special-shaped parts cutting device

Technical Field

The utility model relates to the technical field of special-shaped parts cutting, in particular to a special-shaped parts cutting device.

Background Art

In the daily production of the automobile gearbox industry, various parts with similar ring-like shapes are encountered. Many of these ring-like parts have small inner diameters and require processing of outer circle size precision.

A Chinese patent application with application number 201620398141.8 discloses a cutting die for the outer edge of a non-standard part, including a layered cutting die, which is composed of a plurality of forming blades, each of which is provided with a cutting cavity, each of which has a cutting amount, and also includes a pressure device, which applies pressure to the workpiece to push the workpiece to move in the layered cutting die.

The above-mentioned prior art can achieve the stacking and positioning of multiple special-shaped parts by inserting multiple positioning pins into the through holes opened on the outside of the special-shaped parts, thereby facilitating the use of a cutting knife to cut off the remaining scraps on the outside. However, the distance between each positioning pin cannot be changed according to the size of the special-shaped parts, resulting in that the special-shaped parts that are too large or too small cannot be neatly stacked and positioned, resulting in a narrow scope of application of the cutting device, which is not conducive to use and promotion.

DETAILED DESCRIPTION

In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

Please refer to Figures 1-3. This embodiment provides a device for cutting special-shaped parts, including a base plate 1 and a supporting plate 7 for supporting the special-shaped parts. The supporting plate 7 is fixedly mounted on the upper end surface of the base plate 1, and a positioning assembly for positioning the special-shaped parts is arranged on the outside of the supporting plate 7. Support rods are installed at the four corners of the upper end surface of the supporting plate 7. A cutting blade for cutting special-shaped parts is installed directly above the support rods through a hydraulic cylinder. The special-shaped parts are neatly stacked directly above the supporting plate 7, and the opening of the special-shaped parts is aligned with the middle of the lower end surface of the cutting blade. The hydraulic cylinder is started to allow the cutting blade to enter the interior of the special-shaped parts, thereby achieving the purpose of removing the scraps remaining inside the special-shaped parts.

The positioning assembly includes a positioning plate 4 and a positioning rod 6. At least one transmission plate 5 is slidably installed on both sides of the carrying plate 7. The positioning plate 4 is fixedly installed on the end of the transmission plate 5 away from the carrying plate 7. Connecting plates 2 are slidably installed on both ends of the positioning plate 4. A supporting block 3 is fixedly installed on the end of the connecting plate 2 away from the positioning plate 4. The upper end surface of the supporting block 3 is fixedly installed with a positioning rod 6 along a direction perpendicular to the upper end surface of the base plate 1. The special-shaped parts are movably sleeved on the outside of the positioning rod 6. When it is necessary to position special-shaped parts of different sizes, the distance between the two positioning plates 4 is adjusted according to the size of the special-shaped parts, and then the distance between the two adjacent supporting blocks 3 is adjusted. The purpose of accurately adjusting the distance between the positioning rods 6 can be achieved, thereby making it adapt to special-shaped parts of different sizes, improving the application range of the cutting device, and being conducive to the use and promotion of the cutting device in actual conditions.

At least one sliding groove is provided on both sides of the supporting plate 7, and the transmission plate 5 is slidably installed in the inner cavity of the sliding groove. Two sliding grooves are symmetrically provided on both sides of the supporting plate 7, and transmission plates 5 slide in the inner cavities of the two sliding grooves. The two transmission plates 5 are both connected to the positioning plate 4, which improves the sliding stability of the positioning plate 4 and its own strength.

A through hole connected to the inner cavity of the sliding groove is provided on the side adjacent to the bearing plate 7 and the sliding groove, and a latch pin 9 is slidably inserted in the inner cavity of the through hole. A plug-in groove matched with the latch pin 9 is provided on the side of the transmission plate 5 close to the through hole. When the transmission plate 5 slides to the point where the middle of the opening end of the plug-in groove is on the same horizontal line as the middle of the opening end of the through hole, the latch pin 9 is inserted into the inner cavity of the plug-in groove, so as to achieve the purpose of positioning the transmission plate 5 and prevent the transmission plate 5 from shaking when the cutting tool cuts special-shaped parts.

Furthermore, a plurality of plug-in slots are provided on one side of the transmission plate 5 , and the transmission plate 5 that slides to different positions can be positioned through the cooperation between the latch pin 9 and the plurality of plug-in slots.

One end of the positioning plate 4 is provided with a slide groove connected to the other end thereof, and two connecting plates 2 are symmetrically slidably installed in the inner cavity of the slide groove. The slide groove can limit the sliding trajectory of the positioning plate 4 so as to improve the sliding stability of the connecting plates 2.

The outer wall of the connecting plate 2 is inlaid with at least one limiting ball 8, and the inner wall of the slide groove is provided with a slot adapted to the limiting ball 8. When the limiting ball 8 is engaged with the slot, the resistance of the connecting plate 2 when sliding can be increased, thereby achieving a limiting effect on the limiting ball 8.

Furthermore, a plurality of limiting balls 8 are inlaid on one side of the connecting plate 2, and a plurality of card slots are opened on the inner wall of the slide groove. Through the cooperation between the plurality of limiting balls 8 and the card slots, the connecting plate 2 that slides to different positions can be positioned to prevent the connecting plate 2 from shaking when the cutting tool cuts the special-shaped parts.

The length of the support block 3 along its own vertical direction is the same as the length of the supporting plate 7 along its own vertical direction. When the bottom of the special-shaped part contacts the upper end surface of the supporting plate 7, the bottom of the special-shaped part can fit with the upper end surface of the support block 3 to prevent a gap from being generated between the two, which would cause shaking when the scraps of the special-shaped part are cut.

The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
