Description

Technical Field

[0001] This invention belongs to the field of cutting machine tool technology, and in particular relates to a cutting machine tool for machining metal castings. Background Technology

[0002] Casting is the process of pouring liquid metal into a casting cavity that conforms to the shape of the part, and then letting it cool and solidify to obtain the part or blank. The resulting casting is called a metal casting. Currently, metal castings are widely used in industrial production. After casting, metal castings need further processing to meet different needs. Among these processes, metal casting cutting is one of the subsequent processing steps.

[0003] During the machining of shaft-shaped castings using a disc cutter, after the high-speed rotating disc cutter comes into contact with the shaft-shaped casting, most of the metal chips generated during cutting detach from the shaft-shaped casting in the form of jets. Existing cutting equipment lacks a specific chip collection structure, which easily causes metal chips to fly everywhere, increasing the workload of subsequent cleaning. At the same time, most existing cutting machine tools can only complete the machining of a single casting. After the cutting is completed, the casting must be removed and re-clamped to continue the cutting process, which makes it impossible to achieve the machining of castings in batches, thus greatly reducing the efficiency of casting machining. Summary of the Invention

[0004] The purpose of this invention is to provide a cutting machine tool for metal casting processing. Through the specific structural design of the casting positioning mechanism, cutting control mechanism and water cooling mechanism, the problem that existing cutting equipment cannot achieve batch cutting of castings is solved, thereby greatly reducing the efficiency of casting cutting.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: The present invention is a cutting machine tool for processing metal castings, including a casting positioning mechanism and a cutting control mechanism, wherein the cutting control mechanism is disposed above the casting positioning mechanism; the casting positioning mechanism includes a casting positioning assembly; wherein, the casting positioning assembly includes a lifting seat, a clamping positioning cylinder is fixed on the top of the lifting seat, a spray channel is provided on the clamping positioning cylinder, and self-replenishing water pipes located on both sides of the clamping positioning cylinder are fixed on the top of the lifting seat, the self-replenishing water pipes are connected to the spray channel, and the self-replenishing water... A self-resetting water-pressing part is provided above the pipe, which is coaxial with it. The self-resetting water-pressing part is used to press the cooling water in the self-replenishing water pipe into the spray channel. The cutting control mechanism includes a lifting cutting water filter box. A spray part adapted to the spray channel is installed inside the lifting cutting water filter box. A rotating cutter disc is provided inside the lifting cutting water filter box. A cutting cutter is fixedly installed at the bottom of the rotating cutter disc. During the cutting process of the cutting cutter rotating to cut the top of the metal casting, the cutting is completed by the metal casting rising and feeding on the lifting seat.

The water-pressing piston is fixed to the bottom of the water-pressing rod and close to the top opening of the self-replenishing water pipe. The elastic element is fixed to the bottom of the connecting plate at the top of the water-pressing rod.

[0009] In this embodiment of the invention, the clamping positioning cylinder is provided with multiple clamping parts around its periphery. Each clamping part includes two symmetrically arranged medium air pressure boxes. A support frame two is fixed to the side of the vertical guide plate near the vertical limiting member. The support frame two is fixedly connected to the medium air pressure box at the corresponding position. The medium air pressure boxes between each set of clamping parts are connected by a fixing plate. The top of the water pressure rod slides through the support frame two. The elastic member one is fixed to the top of the support frame two.

[0010] In this embodiment of the invention, a piston plate is slidably disposed inside the medium-density air compressor box. A radial moving rod extending slidably to the inner side of the clamping positioning cylinder is fixed on one side of the piston plate. An arc-shaped clamping member fixed to the radial moving rod is disposed inside the clamping positioning cylinder. An elastic member two connected to the piston plate is disposed inside the medium-density air compressor box. A casting positioning groove coaxial with the bottom of the clamping positioning cylinder is disposed. An air guide pipe one is connected to one side of the medium-density air compressor box. An air guide pipe two is connected to one end of the air guide pipe one. An air guide pipe three is connected between the two air guide pipe two. A solenoid valve is fixedly installed on the air guide pipe three.

[0011] In this embodiment of the invention, a chip guide cone is fixed at the bottom of the lifting cutting water filter box, and a casting opening coaxial with the chip guide cone is provided at the bottom of the lifting cutting water filter box. A cutting motor is installed at the top of the lifting cutting water filter box, and the rotating cutter head is connected to the output shaft of the cutting motor. The spraying part includes a porous spraying element installed on the inner wall of the lifting cutting water filter box. A spraying water inlet pipe is connected to one side of the porous spraying element, and one end of the spraying water inlet pipe passes through the lifting cutting water filter box.

[0012] In this embodiment of the invention, the invention further includes a conveying guide rail, on which a support frame is slidably mounted. A lifting cylinder connected to the lifting cutting water filter box is installed inside the support frame. A guide channel is provided on the support frame. Support seats are fixed on opposite sides of the lifting cutting water filter box. The support seats are slidably connected to the guide channel. Vertical stops are fixed on opposite sides of the lifting cutting water filter box.

[0013] In this embodiment of the invention, the invention further includes a water-cooling mechanism; wherein, the water-cooling mechanism includes a water-cooling chassis, with limit rails fixed on both opposite sides of the water-cooling chassis, inclined sliding seats slidably connected to the limit rails, and power screws rotatably mounted on both opposite sides of the water-cooling chassis, the inclined sliding seats being sleeved on the power screws and threaded together, a sprocket being fixedly mounted at the end of the power screw, and the two sprockets being connected by a transmission chain; a power motor is mounted on one side of the water-cooling chassis, the output end of the power motor being connected to the corresponding power screw, and an air supply device is mounted on the other side of the water-cooling chassis, the air outlet of the air supply device being connected to an air supply pipe, the air supply pipe being connected to each of the air guide pipes above it in a three-way connection, and several sets of positioning plates are fixedly mounted at the bottom inside the water-cooling chassis, with a positioning cavity provided between each set of positioning plates, and the casting positioning mechanism being installed inside the positioning cavity.

[0014] The present invention has the following beneficial effects: 1. When the rotating cutter head is controlled to rotate rapidly by the cutting motor, the various cutting cutters on the rotating cutter head can be driven to move in a circumferential direction. During the cutting process, the cooling water sprayed by the multi-hole spray can cut the cutting cutter and the cutting position of the metal casting at the set position. The cut metal chips fall into the lifting cutting water filter box for effective collection. The metal chips and cooling water generated during high-speed rotation are restricted to the inside of the lifting cutting water filter box by the action of the inner wall of the lifting cutting water filter box. The metal chips stay inside the lifting cutting water filter box, while the cooling water flows out through the filter screen at the bottom of the lifting cutting water filter box to complete the return flow. The spray water can not only cool down the cutting cutter and the metal casting during the cutting process, but also wash away the metal chips attached to the cutting part of the metal casting. In this way, the influence of the attached metal chips on the cutting can be avoided, so as to ensure the cutting quality of the metal casting end.

[0015] 2. In this invention, when the inclined plane pusher seat is moved from one position to another by a power screw, the bottom of the lifting guide is pressed by the inclined plane pusher seat, causing it to gradually slide upward along the inclined plane pusher seat until the bottom of the lifting guide slides to the horizontal surface of the top of the inclined plane pusher seat. At this time, the entire casting positioning assembly is lifted to the set position. In this process, the upward feeding action and cutting action of the metal casting are realized. After the cutting of the metal casting at one position is completed, the inclined plane pusher seat is moved from one position to another by the power screw. The entire casting positioning assembly at the cutting position moves downward under its own weight to complete the reset. At this time, the casting positioning assembly at the position is moved upward by the pressing action of the inclined plane pusher seat to the set position. In this way, the automated cutting of the metal casting at each position can be realized. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] For a specific implementation example, please refer to Implementation Example 1. Figure 1-11This invention relates to a cutting machine tool for processing metal castings, comprising a casting positioning mechanism 1 and a cutting control mechanism 2, wherein the cutting control mechanism 2 is disposed above the casting positioning mechanism 1; the casting positioning mechanism 1 includes a casting positioning assembly 3; wherein the casting positioning assembly 3 includes a lifting seat 301, a clamping positioning cylinder 302 is fixed to the top of the lifting seat 301, a spray channel is provided on the clamping positioning cylinder 302, and self-replenishing water pipes 303 located on both sides of the clamping positioning cylinder 302 are fixed to the top of the lifting seat 301, the self-replenishing water pipes 303 are connected to the spray channel, and a self-resetting pressure water pipe is provided coaxially above the self-replenishing water pipe 303. The self-resetting water pressurizing unit is used to pressurize the cooling water in the self-replenishing water pipe 303 into the spray channel; the cutting control mechanism 2 includes a lifting cutting water filter box 201, a spray unit adapted to the spray channel is installed inside the lifting cutting water filter box 201, a rotating cutter disc 202 is provided inside the lifting cutting water filter box 201, and a cutting cutter 203 is fixedly installed at the bottom of the rotating cutter disc 202. During the cutting process of the cutting cutter 203 rotating to cut the top of the metal casting 4, the cutting is completed by the metal casting 4 rising and feeding on the lifting seat 301. Cooling water enters the spray unit along the spray channel to spray cooling water on the cutting cutter 203 and the metal casting 4.

[0031] In this embodiment of the invention, such as Figure 4 and Figure 5 As shown, the casting positioning mechanism 1 also includes a lifting guide assembly 5; wherein, the lifting guide assembly 5 includes two vertical guide plates 501 arranged symmetrically, and vertical limiters 502 and limit openings 503 are respectively provided on the vertical guide plates 501, and the lifting seat 301 is slidably arranged between the two vertical limiters 502. Two flow guide cavities are symmetrically arranged inside the clamping and positioning cylinder 302. The self-replenishing water pipe 303 is connected to the corresponding flow guide cavity through a horizontal flow guide pipe 304. A hollow flow guide ring 305 connected to the two flow guide cavities is installed on the periphery of the clamping and positioning cylinder 302. An L-shaped flow guide pipe 306 is connected to the periphery of the hollow flow guide ring 305. The spray channel is composed of the horizontal flow guide pipe 304, the flow guide cavity, the hollow flow guide ring 305 and the L-shaped flow guide pipe 306. In this embodiment, the self-replenishing water pipes 303 on both sides of the clamping and positioning cylinder 302 are always below the water surface to ensure that each self-replenishing water pipe 303 is always filled with cooling water. When the cooling water inside the self-replenishing water pipe 303 is squeezed, the cooling water in the self-replenishing water pipe 303 enters the L-shaped flow guide pipe 306 along the horizontal flow guide pipe 304, the flow guide cavity and the hollow flow guide ring 305, and is then lifted into the spray channel by the L-shaped flow guide pipe 306.

[0032] In this embodiment of the invention, such as Figure 5 , Figure 6 and Figure 7As shown, two support frames 307 are symmetrically fixed on the top of the lifting seat 301. The support frames 307 slide through the corresponding limiting openings 503. The vertical guide plate 501 is provided with a lifting guide 308 fixed to the support frame 307 on the side away from the vertical limiting member 502. The self-resetting water pressurizing part is composed of a water pressurizing rod 309, a water pressurizing piston 310 and an elastic member 311. The water pressurizing piston 310 is fixed at the bottom of the water pressurizing rod 309 and close to the top opening of the self-replenishing water pipe 303. The elastic member 311 is fixed at the bottom of the connecting plate at the top of the water pressurizing rod 309.

[0033] Furthermore, the clamping positioning cylinder 302 is provided with multiple clamping parts around its periphery. Each clamping part includes two symmetrically arranged air compressor boxes 312. A support frame 313 is fixed to the side of the vertical guide plate 501 near the vertical limiting member 502. The support frame 313 is fixedly connected to the air compressor box 312 at the corresponding position. The air compressor boxes 312 between each set of clamping parts are connected by a fixing plate. The top of the water pressure rod 309 slides through the support frame 313. The elastic member 311 is fixed to the top of the support frame 313.

[0034] Furthermore, a piston plate 314 is slidably disposed inside the intermediate air compressor box 312. A radial moving rod 315, which extends slidably to the inner side of the clamping positioning cylinder 302, is fixed on one side of the piston plate 314. An arc-shaped clamping member 316, fixed to the radial moving rod 315, is disposed inside the clamping positioning cylinder 302. An elastic member 317, connected to the piston plate 314, is disposed inside the intermediate air compressor box 312. A casting positioning groove 318, coaxial with the inner bottom of the clamping positioning cylinder 302, is disposed for placing a metal casting 4 that is compatible with it. An air guide pipe 319 is connected to one side of the air pressure box 312. An air guide pipe 320 is connected to the end of the air guide pipe 319 (the vertical section of the air guide pipe 320 is a telescopic structure, specifically including an outer air pipe and an inner air pipe sleeved inside it). An air guide pipe 321 is connected between the two air guide pipes 320 (specifically, the air guide pipe 321 is fixedly connected to the outer air pipe on the air guide pipe 320 to ensure that the air guide pipe 320 is always connected to the air guide pipe 321). A solenoid valve 322 is fixedly installed on the air guide pipe 321.

[0035] In this embodiment of the invention, such as Figure 9As shown, a chip guide cone 204 is fixed at the bottom of the lifting cutting water filter box 201. A casting opening coaxial with the chip guide cone 204 is provided at the bottom of the lifting cutting water filter box 201. A cutting motor 205 is installed at the top of the lifting cutting water filter box 201. The rotating cutter head 202 is connected to the output shaft of the cutting motor 205. The spraying part includes a multi-hole spray element 206 installed on the inner wall of the lifting cutting water filter box 201. A spray inlet pipe 207 is connected to one side of the multi-hole spray element 206. One end of the spray inlet pipe 207 passes through the lifting cutting water filter box 201. When the rotating cutter head 202 is rapidly rotated by the cutting motor 205, the various spray elements on the rotating cutter head 202 can be driven to rotate. The cutting tool 203 performs a circumferential motion. The cutting trajectory of the cutting tool 203 during rotation is coaxial with the opening of the casting. During the cutting process, the cooling water sprayed by the porous spray component 206 can perform cutting processing on the cutting position of the cutting tool 203 and the cutting position of the metal casting 4. The cut metal chips fall into the lifting cutting water filter box 201 for effective collection. The metal chips and cooling water generated during high-speed rotation are restricted to the inside of the lifting cutting water filter box 201 by the action of the inner wall of the lifting cutting water filter box 201. The metal chips remain inside the lifting cutting water filter box 201, while the cooling water flows out through the filter screen at the bottom of the lifting cutting water filter box 201 to complete the return flow.

[0036] When the metal casting 4 is placed inside the clamping and positioning cylinder 302 and inserted into the casting positioning groove 318, the metal casting 4 is clamped and fixed by the various arc-shaped clamping parts 316 on the inner side of the clamping and positioning cylinder 302. Then, the lifting cutting filter tank 201 is controlled to descend to the set position, so that the lower end of the spray water inlet pipe 207 is close to the upper end of the L-shaped guide pipe 306. At this time, the upper end of the metal casting 4 passes through the casting outlet and the chip guide cone 204 and enters the lifting cutting filter tank. Inside the cavity of 201, close to the cutting tool 203, the cutting motor 205 is then controlled to drive the cutting tools 203 on the rotating cutter head 202 to rotate. At the same time, the entire casting positioning assembly 3 is controlled to gradually rise to achieve the cutting feed action of the metal casting 4. During this process, the cooling water is pressurized by the water pressure piston 310 sliding along the inside of the self-replenishing water pipe 303. The pressurized cooling water in the self-replenishing water pipe 303 flows through the horizontal guide pipe 304, the guide cavity, and the hollow guide ring. 305 enters the L-shaped guide pipe 306, and is then lifted by the L-shaped guide pipe 306 and the spray water inlet pipe 207 into the porous spray element 206. The cooling water sprayed by the porous spray element 206 can perform cutting processing on the cutting position of the cutting tool 203 and the metal casting 4 at the set position. The spray water can not only cool down the cutting tool 203 and the metal casting 4 during the cutting process, but also wash away the metal chips attached to the cutting part of the metal casting 4. This can avoid the influence of the attached metal chips on the cutting, so as to ensure the cutting quality of the end of the metal casting 4. After the cutting processing is completed, the entire casting positioning assembly 3 is first controlled to gradually descend to complete the reset, and then the lifting cutting filter tank 201 is controlled to rise back to the initial position. Then, the clamping and fixing of the metal casting 4 is released by the arc-shaped clamping member 316, and the metal casting 4 that has completed the cutting processing is taken out from the clamping and positioning cylinder 302 and re-clamped and fixed to another metal casting 4 to be processed.

[0037] Specific embodiment two, based on specific embodiment one, such as Figure 3 and Figure 8As shown, the present invention also includes a conveying guide rail 8, on which a support frame 208 is slidably sleeved. The conveying guide rail 8 is mounted on the machine frame and is one of the power system components of the machine tool (which is prior art). The reciprocating motion of the cutting control mechanism 2 on the conveying guide rail 8 is prior art. For example, a motor is installed on the support frame 208 to drive the gear to rotate. A traveling gear seat that meshes with the gear is fixed on the top of the conveying guide rail 8. A lifting cylinder 209 connected to the lifting cutting filter tank 201 is installed on the inner side of the support frame 208. A guide channel 210 is opened on the support frame 208. Support seats 211 are fixed on both sides of the lifting cutting filter tank 201. The support seats 211 and the guide channel 210 are connected. 0. Sliding connection, vertical baffles 212 are fixed on both sides of the lifting cutting water filter box 201. When the lifting cutting water filter box 201 is lowered to the set position by the lifting cylinder 209, the lower end of the spray water inlet pipe 207 is close to the upper end of the L-shaped guide pipe 306. At this time, the upper end of the metal casting 4 passes through the casting port and the chip guide cone 204 and enters the inner cavity of the lifting cutting water filter box 201 and is close to the cutting blade 203. The bottom of the vertical baffle 212 just abuts against the connecting plate at the top of the water pressure rod 309. During the cutting process, the entire casting positioning assembly 3 is gradually raised, so that the water pressure piston 310 gradually enters the self-replenishing water pipe 303 and pressurizes the cooling water. Each elastic element 311 is gradually compressed.

[0038] In this embodiment of the invention, such as Figure 10 and Figure 11As shown, the present invention also includes a water-cooling mechanism 6; wherein, the water-cooling mechanism 6 includes a water-cooling housing 601 (the vertical guide plate 501 is connected to the water-cooling housing 601 by fasteners), and limit rails 602 are fixed on opposite sides of the water-cooling housing 601. An inclined sliding seat 603 is slidably connected to the limit rails 602 (in the initial state, the bottom of the lifting guide 308 abuts against the bottom of the inclined surface of the inclined sliding seat 603, at which time the casting positioning component 3 at this position is in the initial position). The housing 601 has a power screw 604 rotatably mounted on both sides. An inclined sliding seat 603 is fitted onto the power screw 604 with a threaded connection. A sprocket 605 is fixedly mounted at the end of the power screw 604. The two sprockets 605 are connected by a transmission chain 606. The synchronous rotation of the power screws 604 on both sides is achieved through the combined action of the sprockets 605 and the transmission chain 606, thereby driving the synchronous movement of the inclined sliding seats 603 on both sides. The inclined sliding seats are controlled by the power screws 604. When 603 moves from one position to another, the inclined surface of the inclined push seat 603 exerts a squeezing action on the bottom of the lifting guide 308, causing it to gradually slide upward along the inclined surface of the inclined push seat 603 until the bottom of the lifting guide 308 slides to the horizontal surface of the top of the inclined push seat 603. At this time, the entire casting positioning assembly 3 is lifted to the set position. During this process, the upward feeding action and cutting action of the metal casting 4 are realized. After the cutting of the metal casting 4 at one position is completed, the inclined push seat 603 is controlled by the power screw 604 to move from one position to another. The entire casting positioning assembly 3 at the cutting position moves downward under its own weight to complete the reset. At this time, the casting positioning assembly 3 at the position is squeezed upward by the inclined push seat 603 and moves to the set position. In this way, the automated cutting of the metal casting 4 at each position can be realized. The above-mentioned automated control process can be completed by the program set by the controller. A power motor 607 is installed on one side of the water-cooled chassis 601. The output end of the power motor 607 is connected to the corresponding power screw 604. An air supply device 608 is installed on the other side of the water-cooled chassis 601 (this air supply device 608 has air supply and pressure relief functions, which is existing technology and will not be described in detail here). The air outlet of the air supply device 608 is connected to an air supply pipe 609. The air supply pipe 609 is connected to each of the three air guide pipes 321 above it. When the metal casting 4 is placed inside the clamping positioning cylinder 302 and inserted into the casting positioning slot 318, the solenoid valve 322 is opened and air is supplied to the three air guide pipes 321 through the air supply device 608 and the air supply pipe 609. The air in the three air guide pipes 321 enters the middle air supply system along the second air guide pipe 320 and each of the first air guide pipes 319. Inside the air pressure chamber 312, the increased air pressure inside the air pressure chamber 312 generates a thrust on the piston plate 314. The piston plate 314 moves and compresses the elastic element 317, causing the arc-shaped clamping element 316 to gradually approach the metal casting 4 until each arc-shaped clamping element 316 is tightly pressed against the metal casting 4 to achieve clamping and fixation. Then, the solenoid valve 322 and the air supply device 608 are controlled to close. After the cutting process is completed, the air supply device 608 and the solenoid valve 322 can be controlled to open to release the pressure inside the air pressure chamber 312, thus releasing the clamping and fixation of each arc-shaped clamping element 316 on the metal casting 4. Several sets of positioning plates 610 are fixedly installed at the bottom inside the water-cooled casing 601. A positioning cavity 7 is provided between each set of positioning plates 610. The casting positioning mechanism 1 is installed inside the positioning cavity 7.
