Description

Technical Field

[0001] The present application relates to the technical field of machining devices for turning, and in particular, to an integrated cooling and active chip breaking device with multi-degree-of-freedom adjustment. Background Art

[0002] During the process of turning materials with good plasticity, long strip-shaped chips that are difficult to break will be generated, which may entangle the workpiece, tool, and machine tool components, thereby reducing the machining surface quality and damaging the tool and machine tool components. At the same time, the chips are prone to accumulate in the cutting area, and the heat generated during the cutting process is difficult to dissipate, resulting in high temperature at the tip of the tool and accelerating tool wear.

[0003] In the related art, currently, chip breaking is mainly achieved by setting chip breaking grooves, chip breaking blocks on the blade or setting chip breaking devices. However, these chip breaking methods either have a narrow applicable range of cutting parameters or are single in function. At the same time, there is a mutually restrictive relationship between the position of the chip breaking actuator and the cooling nozzle on the turning tool. Thus, in order to improve the chip breaking efficiency, it is easy to have a negative impact on the cooling effect. In another chip breaking method, high-pressure cooling cutting fluid is used alone for chip breaking and cooling. However, this method requires a large amount of cutting fluid, and the cost of the cutting fluid is high. At the same time, it increases the treatment of cutting waste liquid, and the generated waste liquid is easy to volatilize and damage the health of the staff. At the same time, the integration degree of the relevant auxiliary components in the above methods is low, resulting in a complex structure and large volume of the entire device, which is not convenient for disassembly, installation, and maintenance. Based on this, there is an urgent need for a chip breaking device with high chip breaking efficiency, high cooling effect, and an integrated and adjustable chip breaking and cooling structure.

[0036] Compared with the prior art, the technical solution provided by the embodiment of the present application at least includes the following beneficial effects:

[0037] 1) The device of the present application integrally arranges the cooling integrated component and the chip breaking component. Specifically, a first flow channel is opened along the central axis of the transmission shaft, and an annular groove is opened on the outer wall. A plurality of flow through holes communicating with the first flow channel are spaced apart in the annular groove. The cooling connecting piece is coaxially sleeved on the transmission shaft, and a convex platform is circumferentially arranged on the inner wall of the connecting sleeve of the cooling connecting piece. The inner side wall of the convex platform completely covers the annular groove, and a second flow channel is arranged from the buffer cavity to the inner side wall of the convex platform. The chip breaking component is connected to the bottom end of the transmission shaft. The chip breaking component includes a transition sleeve, an adjusting end cover, a chip breaker, and a conical elastic sleeve. Among them, a third flow channel sealed and communicated with the first flow channel is arranged in the chip breaker. A plurality of liquid spraying holes are divergently opened at one end of the third flow channel, and the liquid spraying holes extend to the first surface of the cutting edge. In this way, during the cutting process, the coolant is transmitted from the outside to the cutting edge and sprayed out. The device not only realizes efficient chip breaking but also improves the cooling effect on the cutting head of the turning tool. Moreover, the coolant is transmitted from the inside of the chip breaking component and sprayed out from the cutting edge, further realizing the cooling and temperature reduction of the chip breaking component.

[0038] 2) A convex platform is circumferentially arranged on the inner wall of the connecting sleeve of the cooling connecting piece. The inner side wall of the convex platform completely covers the annular groove, and a second flow channel extending to the inner side wall of the convex platform is opened in the buffer cavity. A first locking nut, a first shaft seal, and a first bearing are arranged below the convex platform, and a second shaft seal, a second locking nut, and a second bearing are arranged above the convex platform. In this way, while ensuring the sealed connection between the flow channel of the cooling connecting piece and the annular groove of the transmission shaft, when the transmission shaft rotates, the relative rotation between the cooling connecting piece and the transmission shaft is realized, and it is convenient for the layout of the external coolant pipeline, realizing the compact structure of the device.

[0039] 3) Through the setting of the buffer cavity and the elastic member arranged in the buffer cavity, one end of the elastic member is connected with a rubber cushion block. Among them, the rubber cushion block is located at the bottom of the connection between the second flow channel and the buffer cavity. When the hydraulic pressure of the input coolant is unstable, the setting of the buffer cavity and its internal structure can effectively absorb part of the hydraulic pressure, and the plurality of flow through holes communicating with the first flow channel are spaced apart in the annular groove. During the rotation of the transmission shaft, the uniform input of the coolant can be effectively guaranteed.

[0040] 4) Through the setting of the azimuth adjustment component, the azimuth adjustment component can adjust the chip breaking component in six degrees of freedom in the front-back, left-right, up-down directions. When the device installs turning tool components of different specifications and sizes or processes workpieces of different specifications and sizes into different shapes, the relative position between the chip breaker of the chip breaking component and the turning tool tip is adjusted through the azimuth adjustment component, so as to further improve the chip breaking effect and the cooling effect on the turning tool tip.

[0041] 5) Through the setting of the chip breaking component, wherein the chip breaking component includes a transition sleeve, an adjustment end cap, a chip breaker and a conical elastic sleeve. One end of the transition sleeve is fixedly connected to one end of the transmission shaft; the conical elastic sleeve and the adjustment end cap are coaxially sleeved on the outer surface of the chip breaker. The tightness of the conical elastic sleeve is controlled by adjusting the tightness of the adjustment end cap, so as to realize the clamping and fixing of the chip breaker, improve the sealing performance at the connection between the chip breaker and the transmission shaft, and also facilitate the disassembly, installation and replacement of the chip breaker.

[0068] Please refer to Figure 1 , Figure 1 which shows a schematic structural diagram of the first perspective of the integrated cooling active chip breaking device of this embodiment. The multi-degree-of-freedom adjustment integrated cooling active chip breaking device includes an installation base 100, a turning tool assembly 200 fixedly installed on the side end face of the installation base 100. The tool tip of the turning tool assembly 200 protrudes beyond the projection contour line of the installation base 100 in the axial direction. An azimuth adjustment assembly 300 is installed on the top surface of the installation base 100. The azimuth adjustment assembly 300 can perform azimuth adjustment in six degrees of freedom of front, back, left, right, up, and down. A power assembly 400 is fixedly connected to one end of the azimuth adjustment assembly 300 away from the installation base 100. A cooling integration assembly 500 and a chip breaking assembly 600 are coaxially connected in sequence to the output shaft of the power assembly 400.

[0069] Among them, the power component 400 is used to drive the chip-breaking component 600 to rotate, so as to actively break chips during the turning process of the turning tool component 200. The cooling integration component 500 is integrated between the power component 400 and the chip-breaking component 600. During the cutting process, the cooling integration component 500 realizes the transmission of the coolant from the outside to the cutting edge of the chip-breaking component 600 and sprays it to the cutting tool tip of the turning tool component 200. The device not only realizes efficient chip breaking but also improves the cooling effect on the cutting tool tip. At the same time, the coolant is transmitted from the inside of the chip-breaking component and sprayed out from the cutting edge of the chip-breaking component, which further realizes the cooling and temperature reduction of the chip-breaking component 600; and the cooling and chip-breaking structures of the device in this embodiment are integrally arranged, with high integration and a compact structure, the device occupies less space, and at the same time, it is convenient for the layout of the coolant delivery pipeline.

[0070] The structures of the mounting base 100, the turning tool component 200, the orientation adjustment component 300, the power component 400, the cooling integration component 500, and the chip-breaking component 600 will be further described below in conjunction with multiple embodiments.

[0071] Please refer to Figure 2 , Figure 2 , which shows a second perspective structural schematic diagram of the integrated cooling active chip-breaking device of this embodiment. The mounting base 100 can be in the shape of a rectangular body. A receiving portion 110 is provided on the outer sidewall of the mounting base 100. The receiving portion 110 can be a groove opened circumferentially along the side surface of the mounting base 100. The turning tool component 200 is disposed in the receiving portion 110, and the tip of the turning tool component 200 protrudes beyond the projection contour line of the mounting base 100 in the axial direction. The turning tool component 200 can be fixed by a screw 120, and the orientation adjustment component 300 can also be fixed by the screw 120. The turning tool component 200 can include a tool shank 210 and a cutting blade 220 provided at the tip of the tool shank 210.

For example, the turning tool component 200 can be in a clamping form or a welding form, which is specifically selected and adjusted according to actual needs.

[0073] Please refer to Figure 3 , Figure 3The partial structural schematic diagram of the integrated cooling active chip breaking device according to this embodiment is shown. The orientation adjustment assembly 300 includes a first-direction adjustment member 310, a second-direction adjustment member 320, and a third-direction adjustment member 330. The first-direction adjustment member 310 is fixedly connected to the edge of the top surface of the installation base 100. Preferably, the first-direction adjustment member 310 is fixed by a screw 120. Of course, other fixing methods can also be used, such as welding, etc., which are specifically selected according to actual requirements. The second-direction adjustment member 320 is slidably connected to the first-direction adjustment member 310, that is, the first-direction adjustment member 310 can move along the length direction of the first-direction adjustment member 310. One end of the third-direction adjustment member 330 is fixedly connected to the surface of the second-direction adjustment member 320. At the same time, the third-direction adjustment member 330 can move along the length direction of the second-direction adjustment member 320. The length direction of the second-direction adjustment member 320 is perpendicular to the length direction of the first-direction adjustment member 310. The third-direction adjustment member 330 is fixedly connected to the power assembly 400. At the same time, the power assembly 400 can be adjusted in height vertically along the length direction of the third-direction adjustment member 330.

[0074] Please refer to Figure 4 and Figure 5 , Figure 4 The structural schematic diagram of the first-direction adjustment member of this embodiment is shown. The first-direction adjustment member 310 includes a guide rail base 311 arranged on the surface of the installation base 100, a screw rod slide rail 312 arranged on the surface of the guide rail base 311, and a support plate 315 arranged on the surface of the screw rod slide rail 312.

A support plate 315 is fixedly connected to the top surface of the screw rod slider 314.

[0075] In this way, by driving the screw rod of the screw rod slide rail 312 to rotate, and then converting the rotational motion into the linear motion of the nut seat 313 and the screw rod slider 314, the horizontal left-right positioning of the chip breaking execution mechanism is realized by moving the screw rod slider 314. The rotational motion of the screw rod of the screw rod slide rail 312 can be controlled manually or automatically, which is specifically selected according to actual requirements.

[0076] Please refer to Figure 5 , Figure 5A structural schematic diagram of the second-direction adjusting member and the third-direction adjusting member of this embodiment is shown. The second-direction adjusting member 320 includes a lead screw optical axis guide rail 321 disposed on the surface of the support plate 315 and an adjusting slider 322 slidably connected to the lead screw optical axis guide rail 321. It should be noted that the length direction of the lead screw optical axis guide rail 321 is perpendicular to the length direction of the lead screw slide rail 312, that is, the first-direction adjusting member 310 can adjust the horizontal movement, and the second-direction adjusting member 320 can adjust the front-back movement.

[0077] Optionally, the third-direction adjusting member 330 includes a vertical guide rail 331 with one end connected to the top surface of the adjusting slider 322 and a vertical slider 332 slidably connected to the vertical guide rail 331.

The vertical slider 332 is slidably connected to the vertical guide rail 331 in the vertical direction. One end of the vertical guide rail 331 can be fixedly connected to the top surface of the adjusting slider 322 by bolts. Of course, other fixing methods can also be used, such as welding or snap connection. Locking bolts 333 and adjusting bolts 334 are respectively arranged on both sides of the vertical slider 332. The locking bolts 333 and the adjusting bolts 334 are used for adjusting and fixing the vertical slider 332 at different positions on the vertical guide rail 331. A connecting plate 335 is fixedly connected to the surface of the vertical slider 332 away from the vertical guide rail 331. The connecting plate 335 and the vertical slider 332 can be fixed by bolts.

[0078] Optionally, the first-direction adjusting member 310, the second-direction adjusting member 320, and the third-direction adjusting member 330 can be adjusted manually. Among them, the first-direction adjusting member 310 and the second-direction adjusting member 320 can adjust their positions by rotating their respective lead screws. The third-direction adjusting member 330 can adjust its position in the vertical direction by moving the vertical slider 332 and then fixing it with the locking bolts 333 and the adjusting bolts 334.

[0079] In this way, through the setting of the orientation adjusting assembly 300, the orientation adjusting assembly 300 can adjust the orientation of the chip-breaking assembly 600 in six degrees of freedom in the front, back, left, right, up, and down directions. When the device installs turning tool assemblies 200 of different specifications and sizes or processes workpieces of different specifications and sizes with different shapes, the relative position between the chip breaker 630 of the chip-breaking assembly 600 and the turning tool tip is adjusted through the orientation adjusting assembly 300, thereby further improving the chip-breaking effect and the cooling effect on the turning tool tip.

[0080] Please refer to Figure 6 , Figure 6The structural schematic diagram of the power assembly and the cooling integration assembly of this embodiment is shown. The power assembly 400 includes a fixed seat 410 and an actuator motor 420. The fixed seat 410 can be the upper part and the lower part of the fixed seat. The two parts can be fixedly connected to the actuator motor 420 by hexagon socket head cap screws. The actuator motor 420 can be a DC brushless motor. Of course, the actuator motor 420 can also be selected according to actual needs and is not limited herein. A cooling integration assembly 500 and a chip breaking assembly 600 are fixedly connected to the output shaft end of the actuator motor 420.

[0081] Please refer to Figures 7 to 10 , Figure 7 The structural schematic diagram of the cooling integration assembly and the chip breaking assembly of this embodiment is shown. Figure 8 The structural schematic diagram of the cooling integration assembly of this embodiment with the cooling connection parts removed is shown. Figure 9 The cross-sectional view after the power assembly, the cooling integration assembly and the chip breaking assembly of this embodiment are assembled is shown. Figure 10 Another cross-sectional view after the power assembly, the cooling integration assembly and the chip breaking assembly of this embodiment are assembled is shown; the cooling integration assembly 500 is coaxially connected to the output shaft end of the power assembly 400. Specifically, the cooling integration assembly 500 mainly includes a transmission shaft 510 and a cooling connection part 530. A first connection end 511 is provided at one end of the transmission shaft 510 for coaxial connection with the output shaft of the actuator motor 420. A second connection end 514 is provided at the other end of the transmission shaft 510. The second connection end 514 is used for the installation and fixation of the chip breaking assembly 600. A stepped shape is provided on the surface between the two ends of the transmission shaft 510 to facilitate the installation of each component. A first flow channel 512 is formed along the central axis inside the transmission shaft 510, and an annular groove 513 is formed on the outer wall of the transmission shaft 510. A plurality of through holes 5131 communicating with the first flow channel 512 are spaced apart in the annular groove 513.

[0082] It should be noted that the opening of the first flow channel 512 penetrates through the second connection end 514 but is blocked near the first connection end 511. That is, after the coolant flows into the first flow channel 512, it can only flow into the chip breaking assembly 600 from the bottom end. The through holes 5131 are evenly formed on the bottom surface of the annular groove 513. Preferably, the central axes of the through holes 5131 intersect with the central axis of the first flow channel 512. In this way, it is ensured that during the rotation of the transmission shaft 510, the coolant can flow into the first flow channel 512 evenly.

[0083] In some embodiments, on the outer peripheral surface of the transmission shaft 510, a first locking nut 560, a lower end cover 540, a first bearing 550, a first shaft seal 570, a cooling connection member 530, a second shaft seal 571, a second locking nut 561, a second bearing 551, and an upper end cover 520 are coaxially sleeved in sequence from one end close to the second connection end 514, and the first locking nut 560 is fixedly connected to the transmission shaft 510.

[0091] Please refer to Figures 10 to 12 , Figure 10 which shows another cross-sectional view after the power component, the cooling integration component and the chip breaking component of this embodiment are assembled, Figure 11 which shows the structural schematic diagram of the chip breaking component of this embodiment, Figure 12The structural schematic diagram of some components of the chip-breaking component according to this embodiment is shown.

The chip-breaking component includes a transition sleeve 610, an adjustment end cap 620, a chip breaker 630, and a conical elastic sleeve 640. One end of the transition sleeve 610 is fixedly connected to one end of the transmission shaft 510 close to the first locking nut 560, for example, by interference fit plus screws, or directly by bolts, and can be specifically selected according to actual requirements; the conical elastic sleeve 640 and the adjustment end cap 620 are coaxially sleeved on the outer surface of the chip breaker 630, and the adjustment end cap 620 is fixedly connected to one end of the transition sleeve 610 away from the transmission shaft 510.

One end of the chip breaker 630 passes through the transition sleeve 610 and is hermetically connected to the transmission shaft 510, and the conical end of the conical elastic sleeve 640 is embedded in the transition sleeve 610. In this way, the conical elastic sleeve 640 is used for clamping and fixing the chip breaker.

[0093] Optionally, the chip breaker 630 includes a connecting rod 631 and a cutting edge 632.

At this time, the first surface 6321 can be made relative to the tool tip of the turning tool, that is, a plurality of liquid spraying holes 633 are aligned with the tool tip of the turning tool. When the coolant sprays out from the first surface 6321, the tool tip of the turning tool can be better and effectively cooled.

[0095] It should be noted that the number of the liquid spraying holes 633 can be multiple, and the openings of the multiple liquid spraying holes 633 on the first surface 6321 are preferably equidistantly arranged, so as to improve the cooling effect of the turning tool.

The first part is the flow channel in the cooling connector 530, and the second part is the cooling flow channel inside the chip breaking component 600. The flow direction of the cooling medium is to flow into the internal flow channel of the cooling connector 530 through the cooling outer joint 533, then through the outer hole of the transmission shaft 510, flow into the transmission shaft 510, and finally flow from the transmission shaft 510 into the internal flow channel of the chip breaking component 600, and flow out from the liquid spraying holes 633 corresponding to the cooling flow channels in 8 directions at the bottom of the chip breaking component 600.

First add two shaft seals in the connecting sleeve 531, and then install the whole into the transmission shaft 510. Subsequently, install the shaft retaining ring and the first bearing 550 in sequence. The first locking nut 560 is used to fix the first bearing 550. Then place a silica gel flat washer at the connection between one end of the chip breaking component 600 and the transmission shaft 510 for fixed installation. Finally, the cooling connector 530 is fixed on the lower end cover 540 through connecting bolts to complete the assembly of the entire cooling system.

[0099] In the above embodiments, the active chip-breaking device integrates the cooling integrated component 500 and the chip-breaking component 600. Specifically, a first flow channel 512 is formed along the central axis of the transmission shaft 510, and an annular groove 513 is formed on the outer wall.
