Description

Technical Field

[0001] The invention relates to the field of mechanical processing devices, and in particular to a mechanical processing cutting device for mechanical manufacturing. Background Art

[0002] Machining refers to the process of changing the shape, size or performance of a workpiece through mechanical equipment. According to different processing methods, machining can be divided into two categories: cutting and pressure processing. Cutting is to remove excess material on the workpiece through the relative movement of the tool and the workpiece, thereby changing the shape and size of the workpiece; pressure processing is to apply external force to make the workpiece plastically deform to achieve the desired shape and size.

[0003] In the field of mechanical manufacturing, cutting devices are one of the indispensable equipment in mechanical processing. It is widely used in the cutting of materials such as metals, plastics, and wood to meet the size and shape requirements of different workpieces. However, the existing mechanical processing cutting devices for mechanical manufacturing still have some technical problems in practical applications, which affect the processing accuracy and efficiency.

[0004] First of all, existing cutting devices often have difficulty in firmly positioning and fixing the workpiece during the cutting process. Since the workpiece is subject to the cutting force during cutting, if the positioning is not firm, the workpiece is prone to offset or displacement, resulting in the size and shape of the workpiece after cutting not meeting the design requirements. Especially in high-precision processing situations, a slight deviation of the workpiece will have a significant impact on the quality of the final product. For example, in high-end manufacturing fields such as aerospace and automobile manufacturing, the dimensional accuracy requirements of the workpiece are extremely high, and any slight deviation may cause product failure or performance degradation. Therefore, how to achieve accurate positioning and firm fixation of the workpiece during the cutting process is an important technical problem facing current cutting devices.

[0005] Secondly, the existing cutting device is prone to generate high temperature during the cutting process, resulting in reduced cutting accuracy or even deformation of the workpiece. In the cutting process, the friction between the tool and the workpiece will generate a lot of heat, especially in high-speed cutting or hard material processing, the temperature rise is more significant. High temperature will not only accelerate the wear of the tool and reduce the service life of the tool, but also affect the material properties of the workpiece. For example, metal materials will undergo thermal expansion at high temperatures, causing changes in the size of the workpiece, which in turn affects the cutting accuracy. In addition, high temperature may also cause oxidation or phase change on the surface of the workpiece, change the mechanical properties of the workpiece, and even cause deformation or cracking of the workpiece. These problems are particularly prominent in high-precision machining and thin-walled parts machining, seriously affecting the machining quality and production efficiency of the workpiece.

[0006] In summary, the existing mechanical processing and cutting devices for mechanical manufacturing still have many technical problems in workpiece positioning and cutting temperature control. These problems not only affect the processing accuracy and quality of the workpiece, but also limit the application scope and production efficiency of the cutting device. Therefore, how to solve these problems and improve the processing accuracy and adaptability of the cutting device is a technical problem that needs to be solved urgently in the current mechanical manufacturing field. Summary of the invention

[0007] The present invention aims to provide a mechanical processing cutting device for mechanical manufacturing, which solves the problem that the existing cutting device has excessively high temperature during the cutting process, thereby affecting the processing accuracy.

[0060] Six negative pressure blades 21 are circumferentially welded on the output shaft of the first drive motor 20; in this embodiment, the air inlet is arranged outside the negative pressure blade 21, which can avoid the problem that the inhaled debris affects the negative pressure blade 21. A suction chamber 22 is also adhered to the bottom of the processing table 8, and the suction chamber 22 covers the air inlet and the negative pressure blade 21. The left and right sides of the suction chamber 22 are connected to the air outlet pipe 23 located outside the negative pressure blade 21, and each air outlet pipe 23 is installed with a one-way valve 24; a through hole is opened in the center of the suction chamber 22, and the output shaft of the first drive motor 20 is rotatably sealed and connected to the through hole.

[0061] An air inlet hole is provided on the processing table 8, the air inlet hole connects the space of the box body 1 above the processing table 8 with the box body 1 below, and the upper end of the air inlet hole is connected with the air inlet hose 17;

[0062] The air collecting chamber 25 has the same cross-sectional shape as the clamping block 18, but the corresponding dimensions are proportionally reduced. The air collecting chamber 25 is disposed in the clamping block 18, and the inclined structure on the upper side of the air collecting chamber 25 faces the center of the clamping area;

[0063] Two air outlet hoses 26, the two air outlet hoses 26 will respectively connect the corresponding air collecting chambers 25 with the ventilation pipe 10, and the two air outlet hoses 26 are respectively arranged in the grooves 9 directly below the clamping block 18;

[0064] A plurality of air outlet holes 27 are distributed in an array on the inclined structure of the clamping block 18 and are connected to corresponding positions of the air collecting cavity 25 .

[0065] The lateral displacement mechanism and the longitudinal displacement mechanism, the lateral displacement mechanism is used to adjust the spacing between the two clamping blocks 18, and the longitudinal adjustment mechanism is used to adjust the position of the movable plate 13. In this embodiment, the lateral displacement mechanism and the longitudinal displacement mechanism are both composed of a second drive motor 28 and a threaded rod 29, the second drive motor 28 of the lateral displacement mechanism is bolted in the slide groove 14, and the threaded rod 29 of the lateral displacement mechanism is threadedly connected to the slider 19; the second drive motor 28 of the longitudinal displacement mechanism is bolted to the rear side of the processing table 8, and the threaded rod 29 of the longitudinal displacement mechanism is threadedly connected to the middle of the movable plate 13.

[0066] In this embodiment, the cylinder 5 , the first drive motor 20 , the second drive motor 28 and the third drive motor 6 are electrically connected to a controller 30 , which is installed on the front side of the housing 1 .

[0067] The working process of this embodiment is as follows:

[0068] Before cutting, the workpiece is first placed in the middle of the movable plate 13, and then the transverse displacement mechanism and the longitudinal positioning mechanism are turned on through the controller 30. With the help of the transverse displacement mechanism, the two threaded rods 29 and the two sliders 19 can drive the clamping blocks 18 to move toward each other to clamp the workpiece; after the longitudinal displacement mechanism is started, the threaded rod 29 can be used to drive the movable plate 13 forward or backward for a certain period of time. After the movable plate 13 moves to the predetermined position, the second drive motor 28 is turned off. With the help of the threaded rod 29, the stability of the movable plate 13 and the clamping block 18 can be ensured, thereby avoiding the situation in which the workpiece is shifted and damaged due to vibration during the processing.

[0069] After the workpiece is clamped, the cylinder 5, the third drive motor 6 and the first drive motor 20 are started through the controller 30. After the cylinder 5 is started, it can drive the third drive motor 6 and the grinding wheel 7 to move toward the workpiece. After the third drive motor 6 is started, the high-speed rotation of the grinding wheel 7 can be used to achieve the cutting operation of the workpiece. When performing a cutting operation, the first drive motor 20 is started and can drive the negative pressure blade 21 to rotate. After the negative pressure blade 21 rotates, suction is generated in the suction chamber 22. At this time, the suction generates an attraction force on the air inlet channel 15 through the air inlet hole, the air inlet hose 17, and the air guide box 16, so that the debris generated during the cutting process can be sucked into the air guide box 16, and discharged into the box body 1 under the pressurizing platform along the air inlet hose 17, the air inlet hole, the suction chamber 22 and the air outlet pipe. Since the air outlet pipe is directly opposite to the collection chamber 12 of the sponge pad 11, the debris can directly enter the collection chamber 12 with the air, so that the debris can be collected with the help of the pores of the sponge pad 11, thereby reducing the situation where the debris flies everywhere in the box body 1 with the air, which is conducive to maintaining the stability of the first drive motor 20.

[0070] After entering the collecting chamber 12, the air can also enter the air collecting chamber 25 through the pores, the vent pipe 10 and the air outlet hose 26, and finally blow toward the workpiece through the air outlet. The circulating flow of air can reduce the processing temperature of the workpiece surface, and at the same time, the debris generated by cutting on the workpiece surface can be blown toward the air inlet channel 15, effectively maintaining a low-temperature, clean processing environment and improving the cutting accuracy and effect.

[0071] The above are only embodiments of the present invention, and the common knowledge such as the known specific structures and / or characteristics in the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
