Description

Technical Field

[0001] The invention relates to the technical field of machine tool processing, in particular to a turning and milling compound processing center. Background Art

[0002] Turning and milling is a combination of turning and milling on a single machine tool to achieve high-efficiency, high-precision machining results. A lathe toolholder is a commonly used type of turning and milling machine. By installing and replacing different turning and milling tools on the toolholder, the toolholder moves horizontally and vertically under the control of a CNC system, allowing tools at different positions to be moved to the part clamped by the spindle chuck, making it easier to perform turning and milling on the part.

[0003] There are multiple tools installed on the tool holder, and multiple tools are needed for turning and milling of a part. At present, the tool replacement process is mainly carried out by moving the tool holder through the moving part on the lathe, and the tool holder then transfers the tools in different positions to the part turning and milling station. When the two tools used successively are far apart, the moving part needs to drive the tool holder to move a long distance, resulting in a lot of time spent on adjusting the tool holder and tool position, which in turn affects the efficiency of the part turning and milling. In addition, during the turning and milling process, turning and milling chips will splash onto the surface of the spare tool. If the chips on the spare tool are not cleaned in time, it will easily affect the quality of the turning and milling products. Summary of the Invention

[0004] The object of the present invention is to provide a turning-milling compound machining center to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A turning-milling composite machining center, comprising:

[0007] A lathe body, wherein a transverse moving portion is installed inside the lathe body, and a longitudinal moving portion is installed on top of the transverse moving portion;

[0008] The tool row seat is fixed on the top of the longitudinal moving part, and the top of the tool row seat is rotatably connected to the screw rod 1 and the screw rod 2;

[0009] A plurality of mounting seats are fixed on the top of the tool row seat, and a tool assembly is fixed on the top of the mounting seat, and the tool assembly includes a tool;

[0010] There are two swing arms, the screw rod 1 and the screw rod 2 are respectively screwed and connected to the corresponding swing arms, and the swing arms are used to pick up and place the tool;

[0011] A cleaning assembly is provided on one side of the tool bar seat, the cleaning assembly comprising two support seats fixed to the tool bar seat, a cleaning brush roller for cleaning debris from the tool surface is rotatably connected between the two support seats, and the cleaning brush roller is transmission-connected to the second screw rod;

[0012] The arc-shaped box is slidably connected to the inside of the tool holder and is used to apply lubricating oil or cutting fluid to the tool.

[0013] Furthermore, two motors are fixed to one end of the tool holder, and the screw rod 1 and the screw rod 2 are respectively fixed to the output ends of the motors at corresponding positions, and the screw rod 1 and the screw rod 2 are two components with the same structure.

[0014] Furthermore, one side of the tool seat is an inclined surface, and a guide block is fixed on the top of the other side of the tool seat.

[0015] Furthermore, two sponge blocks are filled and fixed inside the arc box, and the center of the arc of the arc box is on the axis where the screw rod 1 is located.

[0016] Furthermore, an arc-shaped chamber is provided at one end of the tool stand, an oil tank is fixed inside the tool stand, and a hose is fixedly connected between the oil tank and the arc-shaped chamber.

[0017] Furthermore, a plurality of arc-shaped holes are formed at equal intervals on the top of one end of the arc-shaped box, a plurality of branch holes are formed outside the arc-shaped holes, and the branch holes are connected to the inner space of the arc-shaped box.

[0018] Furthermore, a first electromagnet is embedded and fixed on the top surface of the mounting seat, and a second electromagnet is embedded and fixed on one side of the swing arm.

[0019] Further, the tool assembly further comprises:

[0020] The support block is detachably fixed to the mounting base by adsorption;

[0021] There are two wedge-shaped blocks, which are detachably fixed to the electromagnet;

[0022] The cover plate is detachably fixed to the top surface of the support block by screws, and the tool is installed and fixed at a position between the cover plate and the support block.

[0023] Furthermore, a brush is sleeved and fixed on the outer side of the cleaning brush roller, and a shaft rotatably connected to the support seat is inserted and fixed on the inside of the cleaning brush roller.

[0024] Furthermore, one end of the shaft and one end of the second screw rod are both sleeved and fixed with a synchronous pulley, and a synchronous belt is connected between the two synchronous pulleys for transmission.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] Finally, the screw rod 1 is rotated counterclockwise, causing the swing arm to flip the adjacent tool assembly to the top of the inclined surface of the tool row seat, thereby automatically removing the spare tool assembly at the adjacent position of the tool assembly 1;

[0027] Similarly, the second screw can be rotated to drive the other swing arm to move to the side of the spare tool assembly that will need to perform the second turning and milling work (hereinafter referred to as tool assembly two). The second screw first rotates counterclockwise to make the electromagnet two on the swing arm absorb and fix the wedge block on the tool assembly two. After the swing arm absorbs and fixes the tool assembly two, the second screw rotates clockwise to make the swing arm move with the tool assembly two to the side of the empty position adjacent to the tool assembly one. The screw then rotates counterclockwise to transfer and fix the tool assembly two to the adjacent position of the tool assembly one, so that after the tool assembly one completes the turning and milling work, the longitudinal moving part only needs to move the tool holder a short distance to enable the tool assembly two to enter the turning and milling work. By transferring and fixing the tool assembly two that will need to perform the turning and milling work later to a position close to the tool assembly one during the turning and milling process of the tool assembly one, the distance between the spare tool assembly two and the working tool assembly one is shortened, and the time for the longitudinal moving part to drive the tool assembly to adjust the position is shortened, which is beneficial to improving the efficiency of the part turning and milling composite processing.

[0028] 2. By rotating the cleaning brush roller connected to the top of one side of the tool holder, when the screw rod 2 rotates clockwise to make the swing arm carry the spare tool assembly and move along the guide block, the tool on the spare tool assembly will be squeezed into the brush inside the cleaning brush roller. At the same time, the rotation of the screw rod 2 will drive the cleaning brush roller to rotate with the brush. The rotating brush can automatically clean the debris attached to the outside of the tool, so that the debris on the tool can be cleaned at the same time during the movement of the spare tool, ensuring the cleanliness of the spare tool and the quality of the subsequent spare tool turning and milling parts.

[0029] 3. An arc box is connected by rotating it with screw 1 as the axis on one side of the tool holder. Two sponge blocks are filled inside the arc box. The sponge blocks are adsorbed with oil (lubricating oil or cutting fluid). When screw 1 rotates counterclockwise to rotate the swing arm with the idle tool assembly away from the mounting seat, the tool on the tool assembly can be inserted between the two sponge blocks, so that the oil on the sponge block can be applied to the outside of the tool. At the same time, when the swing arm moves along the inclined side of the tool holder, the tool can slide between the two sponge blocks, which makes it easy to fully apply the oil adsorbed on the sponge blocks at different positions to the tool, which is beneficial to improve the cooling and lubrication effect of the tool during turning and milling.

DETAILED DESCRIPTION

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0041] For example 1, please refer to Figure 1 - Figure 9 In an embodiment of the present invention, a turning-milling compound machining center includes a lathe body 100, a lateral moving portion 110 is installed inside the lathe body 100, a longitudinal moving portion 120 is installed on the top of the lateral moving portion 110, a tool holder 200 is fixedly installed on the top of the longitudinal moving portion 120, a screw rod 1 210 and a screw rod 220 are rotatably connected to the top of the tool holder 200, a plurality of mounting seats 300 are slidably fixed on the top of the mounting seat 300, a tool assembly 310 is fixed on the top of the mounting seat 300, and the tool assembly 310 includes Including tools, the outer sides of screw rod 1 210 and screw rod 2 220 are screwed together with a swing arm 400 for picking up and placing the tools, and a cleaning component 500 is provided on one side of the tool holder 200. The cleaning component 500 includes two support seats 510 both fixed to the tool holder 200, and a cleaning brush roller 520 for cleaning debris on the surface of the tool is rotatably connected between the two support seats 510. The cleaning brush roller 520 is transmission-connected to the screw rod 220, and an arc box 600 for applying lubricating oil or cutting fluid to the tool is internally slidably clamped on one side of the tool holder 200.

[0042] Specifically, the electromagnet 1 320 is used to absorb and fix multiple tool assemblies 310 on the traditional tool stand 200, and screw rod 1 210 and screw rod 2 220 (hereinafter collectively referred to as screw rods) are rotated on both sides of the multiple tool assemblies 310. A swing arm 400 is screwed and connected to the outside of the screw rod. An electromagnet 2 410 capable of absorbing and fixing the tool assembly 310 is fixed on one side of the swing arm 400. When a tool assembly 310 is performing turning and milling work, the screw rod 1 210 is used to rotate and drive one swing arm 400 to first move the idle tool assembly 310 adjacent to the working tool assembly 310 away, and then the screw rod 220 is used to drive another swing arm 400 to move the tool assembly 310 to be used subsequently. 10 is transferred to the previously moved position, thereby shortening the distance between the two tool assemblies 310 used successively on the tool holder 200. After the turning and milling of one tool assembly 310 is completed, the tool holder 200 moves a shorter distance to enable the other tool assembly 310 to be put into turning and milling work, which is beneficial to improving the efficiency of composite turning and milling. By installing a cleaning brush roller 520 on the top of the tool holder 200, the spare tool can contact the rotating cleaning brush roller 520 during the movement of the spare tool assembly 310. The rotating cleaning brush roller 520 can automatically clean the debris remaining on the outside of the spare tool, ensuring the cleanliness of the spare tool, and thus ensuring the product quality of subsequent spare tool turning and milling parts.

[0043] like Figure 1 As shown, in this embodiment, a chuck capable of rotating the component is installed on the lathe body 100 relative to the tool holder 200, and the transverse moving part 110 and the longitudinal moving part 120 can respectively move the tool holder 200 transversely and longitudinally, so that the tool assembly 310 at different positions on the tool holder 200 can be moved to the end of the component, and the chuck can rotate the component to enable different types of tools to turn and mill the component. This part is the existing technology, and the specific working principle will not be described in detail.

[0044] like Figure 2 As shown, in this embodiment, two motors 230 are fixed at one end of the tool holder 200, and screw rod 1 210 and screw rod 2 220 are respectively fixed to the output ends of the motor 230 at corresponding positions. Screw rod 1 210 and screw rod 2 220 are two components with the same structure. The output end of the motor 230 drives the screw rod (including screw rod 1 210 and screw rod 2 220) to rotate clockwise or counterclockwise, so that the swing arm 400 on the screw rod can not only rotate and reverse to shift the position of the tool assembly 310, but also can make the swing arm 400 move linearly along the guide block 260 or the inclined surface on one side of the tool holder 200, so as to adjust the position of the tool assembly 310 after the flipping movement.

[0045] In this embodiment, the distance between the mounting seat 300 and the screw rod is sufficient for the swing arm 400 to rotate around the screw rod, so that after the swing arm 400 moves to the outside of the mounting seat 300, the swing arm 400 can be rotated to fit against the top surface of the tool holder 200 by utilizing the rotational action of the screw rod, and then slide linearly along the tool holder 200. Specifically, the swing arm 400 on screw rod 1 210 slides backward along the tool holder 200, and the swing arm 400 on screw rod 220 slides forward along the tool holder 200, making it convenient to move the swing arm 400 to one side of the tool assembly 310 at a different position, and then utilize the swing arm 400 to transfer the tool assembly 310.

[0046] like Figure 2 and Figure 5 As shown, in this embodiment, one side of the tool holder 200 is a slope, and a guide block 260 is fixed on the top of the other side of the tool holder 200. The slope and the top slope of the guide block 260 are designed so that after the swing arm 400 abuts against the slope, as the screw rod 210 rotates counterclockwise, the swing arm 400 moves linearly backward along the slope of the tool holder 200, and as the screw rod 220 rotates clockwise, the swing arm 400 slides linearly forward along the top slope of the guide block 260.

[0047] like Figure 2 、 Figure 3 、 Figure 4 As shown, in this embodiment, an electromagnet 1 320 is embedded and fixed on the top surface of the mounting seat 300, and the electromagnet 1 320 can adsorb and fix the wedge block 312 on the tool assembly 310 when energized, and an electromagnet 2 410 is embedded and fixed on one side of the swing arm 400, and the electromagnet 2 410 can adsorb and fix the support block 311 on the tool assembly 310 when energized. After the electromagnet 2 410 is powered off, the electromagnet 1 320 continues to be energized, so that the swing arm 400 can adsorb and fix the tool assembly 310 and flip it away from the mounting seat 300, wherein the support block 311 is designed to be hollowed out in the middle, so as to reduce the overall weight of the tool assembly 310.

[0048] like Figure 3 As shown, in this embodiment, the tool assembly 310 also includes a support block 311 that is detachably adsorbed and fixed to the mounting seat 300, wedge blocks 312 are fixed on both sides of the support block 311, the wedge block 312 and the electromagnet 320 are detachably adsorbed and fixed, and a cover plate 313 is detachably fixed to the top surface of the support block 311 by screws, and the tool is installed and fixed in a position between the cover plate 313 and the support block 311.

[0049] In this embodiment, the screws on the cover 313 can be removed, the cover 313 can be opened, and then different types of cutting tools can be clamped and placed on the top of the support block 311. The cover 313 can then be fixed to the top of the support block 311 with screws to achieve the installation and fixation of the cutting tools on the support block 311 of the cutting tool assembly 310.

[0050] like Figure 2 and Figure 5 As shown, in this embodiment, a brush is fixedly sleeved on the outer side of the cleaning brush roller 520, and a shaft rod rotatably connected to the support seat 510 is fixedly inserted into the interior of the cleaning brush roller 520. One end of the shaft rod and one end of the screw rod 220 are both sleeved and fixed with a synchronous pulley, and a synchronous belt is connected for transmission between the two synchronous pulleys.

[0051] In this embodiment, the rotation of screw rod 220 will drive the shaft to rotate through the transmission action of two synchronous pulleys and synchronous belts, and the shaft will then rotate the cleaning tool with the brush through the cleaning brush roller 520, so that the cleaning brush roller 520 can be synchronously driven to automatically clean the tool during the process of screw rod 220 rotating to drive the swing arm 400 to move.

[0052] like Figure 4 As shown, in this embodiment, for example, the tool assembly 310 at position A is performing turning and milling work on parts, the screw rod 210 can be rotated clockwise to rotate the swing arm 400 moved to the side of position B to rotate and stick to the wedge block 312 of the tool assembly 310 at position B, and then the screw rod 210 is rotated counterclockwise to move the tool assembly 310 at position B away from the side of position A, and the screw rod 220 is first rotated counterclockwise to make the swing arm 400 adsorb and fix the wedge block 312 of the spare tool assembly 310 at position C, and then the screw rod 220 is rotated clockwise to make the swing arm 400 move the spare tool assembly 310 at position C to the side of position B, and finally the screw rod 220 is rotated counterclockwise to make the swing arm 400 transfer the tool assembly 310 at position C to position B, and the electromagnet 2 410 of the mounting seat 300 at position B adsorbs and fixes the tool assembly 310 at position C, so as to automatically transfer the spare tool assembly 310 to the nearest turning and milling station.

[0053] In this embodiment, the screw rod 210 can continue to slide along the inclined surface of the tool holder 200 with the swing arm 400 on its outer side, and move the idle tool assembly 310 moved out from position B to the side close to position C, and then the screw rod 210 rotates clockwise to flip the idle tool assembly 310 to the top of the mounting seat 300 at position C, and the electromagnet 1 320 on the top of the mounting seat 300 at position C adsorbs and fixes the idle tool assembly 310, thereby transferring the idle tool assembly 310 to the principle turning and milling station. Similarly, the two tool assemblies 310 that need to be swapped at the other positions of this application can also use the screw rod to drive the swing arm 400 to achieve the swap. The swapping of other positions will not be described in detail.

[0054] like Figure 5 As shown, in this embodiment, two connecting seats 1 270 and two connecting seats 280 are fixed on the tool holder 200. The two connecting seats 1 270 stably support the screw rod 1 210 to rotate, and the two connecting seats 280 stably support the screw rod 2 220 to rotate.

[0055] Embodiment 2, based on embodiment 1, is to automatically apply oil to the tool to improve the cooling and lubrication effects of the tool.

[0056] like Figure 5 - Figure 8 As shown, in this embodiment, an arc-shaped chamber 240 is provided at one end of the tool holder 200, and an oil tank 290 is fixed inside the tool holder 200. A hose is fixed between the oil tank 290 and the arc-shaped chamber 240, and the hose can pump the oil inside the oil tank 290 into the arc-shaped chamber 240. An arc-shaped box 600 is slidably connected inside the arc-shaped chamber 240, and two sponge blocks 610 are filled and fixed inside the arc-shaped box 600. The center of the arc of the arc-shaped box 600 is on the axis of the screw rod 210. A plurality of arc-shaped holes 620 are provided at equal intervals on the top of one end of the arc-shaped box 600, and a plurality of branch holes 621 are provided on the outside of the arc-shaped hole 620, and the branch holes 621 are connected to the internal space of the arc-shaped box 600.

[0057] In this embodiment, during the process of the swing arm 400 rotating with the tool toward the arc box 600, the tool can be gradually inserted into the sponge block 610, and at the same time, the arc box 600 can rotate around the screw rod 210 toward the inside of the arc chamber 240 to adapt to the moving position of the tool during the rotation process. During the process of the arc box 600 moving toward the inside of the arc chamber 240, the arc box 600 will squeeze the oil pumped through the hose inside the arc chamber 240, so that the oil is squeezed and transported to the inside of the arc hole 620, and then flows along the arc hole 620 through multiple branch holes 621 to the sponge block 610, so as to continuously provide oil to the sponge block 610.

[0058] In this embodiment, a plurality of reset assemblies 250 are arranged at equal intervals between one end of the arc box 600 and the arc chamber 240. The reset assembly 250 includes an arc cylinder 251 fixed to the inner side of the arc chamber 240. An arc rod 252 is slidably engaged inside the arc cylinder 251. A reset spring 253 is fixed between the arc rod 252 and the arc cylinder 251. When the arc box 600 moves into the arc chamber 240, the arc box 600 squeezes the arc rod 252. The arc rod 252 squeezes the return spring 253, so that the return spring 253 fixed between the arc rod 252 and the arc cylinder 251 is in a compressed state. Then, after the tool leaves the arc box 600, the elastic force of the return spring 253 will return the arc box 600 to its initial position. After the arc box 600 leaves the arc chamber 240, space is made for the arc chamber 240, and the hose pumps the spare oil into the space, so that the arc chamber 240 continues to store the spare oil.

[0059] In this embodiment, the shape of the return spring 253 is adapted to the arc shape of the arc tube 251 , and a sealing ring is fixedly sleeved on one end of the arc box 600 close to the arc chamber 240 to prevent oil leakage.

[0060] In the present invention, reference is made to the specification Figure 9 The present application provides a method for supplying power to the electromagnet 2 410. An electric slip ring 1 211 can be installed at one end of the screw, a fixed conductive metal strip 212 can be embedded on the outside of the screw, and an electric slip ring 2 420 can be installed between the swing arm 400 and the screw. Thus, an external wire can supply power to the electric slip ring 1 211. The electric slip ring 1 211 supplies power to the electric slip ring 2 420 of the movable swing arm 400 through the conductive metal strip 212. The electric slip ring 2 420 then transmits the power to the position of the electromagnet 2 410. The specific circuit connection is as follows: There is technology available and detailed description is omitted. Of course, other existing methods can also be used to power the electromagnet 2 410. The specific method can be selected according to needs. It should be noted that the thickness of the conductive metal strip 212 is greater than the depth of the screw thread groove, and the width of the electric slip ring 2 420 is greater than the pitch of the screw, so that the electric slip ring 2 420 can always be electrically connected to the conductive metal strip 212. The outer side of the conductive metal strip 212 is provided with a notch groove that is the same as the external screw thread groove, so as not to affect the screwing movement of the swing arm 400 and the screw.
