Description

Technical Field

[0001] This invention relates to the field of milling machine tool technology, and more specifically to a milling machine tool for metal parts. Background Technology

[0002] Milling is one of the most common machining methods in the manufacturing of metal parts. By using a rotating multi-bladed milling cutter to cut the workpiece, high-precision contours and surface quality can be obtained. It is widely used in aerospace, automobile manufacturing, mold processing and general machinery.

[0003] During milling, high-speed relative motion occurs between the cutting tool and the workpiece, and the metal material is removed layer by layer, inevitably generating a large amount of metal chips. Existing metal milling machine tools usually rely on manual hand-held brushes or compressed air guns to periodically clean the chips on the worktable surface and in the guide grooves. Due to the narrow structure and great depth of the guide grooves on the worktable, conventional brushes cannot reach the bottom of the guide grooves, resulting in chips accumulating at the bottom of the grooves for a long time and incomplete cleaning. Thorough cleaning of the entire machine tool often requires a lot of manpower and time. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a metal parts milling machine tool to solve the problem in the prior art that the guide groove is not thoroughly cleaned and metal chips easily accumulate at the bottom of the groove.

[0005] This invention is achieved through the following technical solution: A milling machine tool for metal parts includes a machine body, a feed system mounted on the side wall of the machine body, a spindle system disposed above the feed system and mounted on the top of the machine body, a worktable disposed between the feed system and the spindle system, a clamp and an auxiliary cylinder respectively embedded on the worktable, an air suction mechanism passing through the interior of the auxiliary cylinder, a cleaning mechanism sleeved on the air suction mechanism, and a blocking mechanism connected to the side wall of the auxiliary cylinder; The auxiliary cylinder includes a cylinder body with limiting holes at both ends.

The suction mechanism includes a pipe with multiple suction nozzles communicating with its interior at the bottom. Each suction nozzle corresponds to a position in one of the air inlets. One end of the pipe is connected to the inner wall of the cylinder body, and the other end of the pipe extends out of the cylinder body through the limiting holes and is fitted with a connector.

[0006] Furthermore, the machine body includes a base that contacts the ground, a bed is fixedly connected to the upper end of the base, and a control box is fixedly connected to the side wall of the bed.

[0007] Furthermore, the feed system includes a gearbox fixedly connected to the side wall of the bed, and the gearbox is equipped with multiple handwheels via a transmission rod, and the multiple handwheels are respectively used to adjust the Y-axis and Z-axis directions of the worktable.

[0008] Furthermore, the spindle system includes a mounting base connected to the side wall of the bed by multiple sets of bolts, a spindle box fixedly connected to the side wall of the mounting base, and a power seat for mounting cutting tools extending from the end of the spindle box.

[0009] Furthermore, a synchronization seat is fixedly connected to each end of the workbench, and an adjustment mechanism is provided on both synchronization seats. The upper surface of the workbench is provided with multiple guide grooves, and the multiple guide grooves are arranged at equal intervals.

[0010] Furthermore, the adjustment mechanism is disposed between the worktable and the gearbox, and the adjustment mechanism includes a ball screw and a screw nut, and the adjustment mechanism is used to adjust the X-axis position of the worktable.

[0011] Furthermore, the fixture includes a bracket set on the upper part of the workbench, a plurality of feet fixedly connected to the bottom of the bracket, and the plurality of feet are all set in guide grooves, a plurality of vertical rods fixedly connected to the top of the bracket, and the upper ends of the plurality of vertical rods are connected to a base. The base is provided with two jaws for fixing the workpiece. One jaw is fixedly connected to the top of the base, and the bottom of the other jaw is provided with a threaded rod and a nut. The nut is connected to the jaw, one end of the threaded rod is rotatably connected to the base, and the other end of the threaded rod extends outside the base and is fixedly connected with a handle. Two positioning seats are symmetrically arranged on the top of the base, and each of the two positioning seats has a through hole along the axial direction.

[0012] Furthermore, the cleaning mechanism includes multiple sleeves, with two connecting blocks fixedly connected between two adjacent sleeves, and the two connecting blocks are symmetrically arranged. Each of the connecting blocks has bristles on its sidewalls, and the bristles extend out of the cylinder body through the through grooves.

[0013] Furthermore, multiple sleeves are disposed on the pipe, and multiple connecting blocks are configured as U-shaped, with the open end of the connecting block corresponding to the position of the suction nozzle, and the length of the opening of the connecting block being greater than the height of the suction nozzle; One end of the sleeve is set in the limiting hole and is rotatably connected to the cylinder body. The other end of the sleeve extends out of the cylinder body and a knob is fixedly connected to the end of the sleeve away from the cylinder body.

[0015] The beneficial effects of this invention are as follows: This metal parts milling machine tool, through its cylindrical body, guide blocks, and partition blocks, can push debris from the worktable surface into the guide groove and scoop up debris deposited at the bottom of the guide groove. Together with the suction nozzle, it specifically cleans the guide groove on the worktable. Simultaneously, the rotating sleeve drives the brush bristles to rotate. The bristles are constrained by the inner wall of the cylinder and remain bent. When they rotate to the through groove, they extend outwards, sweeping the upper and front ends of the guide block and pushing residual debris back to the vicinity of the suction nozzle, improving cleaning efficiency. Furthermore, the repeated contact between the brush bristles and the guide block and the inner wall of the cylinder during rotation shakes off fine debris adhering to the bristles, preventing them from losing their cleaning ability due to debris entanglement. During processing, the baffles and movable plates on both sides can form a shield on both sides of the workpiece, blocking high-speed flying metal debris during milling and reducing the amount of cleaning work after processing.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] In the above description of the present invention, it should be noted that the terms "one side," "the other side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is conventionally placed during use. These terms are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible.

[0024] This invention provides a technical solution: Please refer to Figures 1 to 4 A metal parts milling machine tool includes a body 1, which includes a base 11 in contact with the ground. A bed 12 is fixedly connected to the upper end of the base 11. A control box 13 is fixedly connected to the side wall of the bed 12, which is equipped with a servo amplification system and controller for each feed axis for precise control of each moving part of the machine tool. A feed system 2 is installed on the side wall of the body 1. The feed system 2 includes a gearbox 21 fixedly connected to the side wall of the bed 12. Multiple handwheels 22 are provided on the gearbox 21 through a transmission rod. The multiple handwheels 22 are used to adjust the Y-axis and Z-axis directions of the worktable 4. When the handwheel 22 is turned, the power is transmitted to the gear set in the gearbox 21 through the transmission rod, and then driven by the lead screw and other transmission elements to move the worktable 4 along the Y-axis or Z-axis to achieve precise tool setting and position compensation.

[0025] In addition, a spindle system 3 is provided above the feed system 2 and is installed on the top of the machine body 1. The spindle system 3 includes a fixed seat 31 connected to the side wall of the bed 12 by multiple sets of bolts. It can withstand the huge cutting force and vibration generated during cutting. A spindle box 32 is fixedly connected to the side wall of the fixed seat 31. The spindle box 32 contains spindle components, spindle motor, spindle bearings and other components. The spindle box 32 transmits power to the spindle through the internal transmission mechanism and realizes the speed change and direction change of the spindle according to the processing needs. The end of the spindle box 32 extends to provide a power seat 33 for mounting the cutting tool. The milling cutter is installed in the tapered hole at the lower end of the power seat 33 to realize the milling of the workpiece.

[0026] Furthermore, refer to Figure 5 and Figure 6 A worktable 4 is provided between the feed system 2 and the spindle system 3. Synchronous seats 41 are fixedly connected to both ends of the worktable 4. An adjustment mechanism 42 is shared on both synchronous seats 41. The adjustment mechanism 42 is located between the worktable 4 and the gearbox 21. The adjustment mechanism 42 includes a ball screw and a screw nut, and is used to adjust the X-axis position of the worktable 4. The ball screw passes through mounting holes on the two synchronous seats 41 and can rotate relative to the synchronous seats 41. The screw nut is fixedly connected to the synchronous seats 41. When the operator drives... When the ball screw rotates, it drives the worktable 4 to move along the X-axis through the synchronous seat 41. The workpiece can be adjusted and fed in any position in three mutually perpendicular directions, which meets the multi-directional feeding requirements when machining complex parts. The upper surface of the worktable 4 is provided with multiple guide grooves 43, and the multiple guide grooves 43 are arranged at equal intervals. The guide grooves 43 usually adopt a T-slot structure or a right-angle groove structure to provide positioning and locking. The fixture 5 and the auxiliary cylinder 6 can slide freely in the guide grooves 43 to adjust their positions, and the fixture 5 is locked on the worktable 4 by bolts and nuts.

[0027] Reference Figure 5 and Figure 7A clamp 5 and an auxiliary cylinder 6 are respectively embedded in the workbench 4. The clamp 5 includes a bracket 51 set on the upper end of the workbench 4. Multiple feet 52 are fixedly connected to the bottom of the bracket 51, and the multiple feet 52 are all set in the guide groove 43. Multiple vertical rods 53 are fixedly connected to the top of the bracket 51. The upper ends of the multiple vertical rods 53 are connected to a base 54. The base 54 is provided with two jaws 55 for fixing the workpiece. One jaw 55 is fixedly connected to the top of the base 54. The bottom of the other jaw 55 is provided with a threaded rod and a nut. The nut is connected to the jaw 55. One end of the threaded rod is rotatably connected to the base 54. The other end of the threaded rod extends to the base 54 and is fixedly connected to a handle 56. When in use, the operator places the metal part to be processed between the two jaws 55, rotates the handle 56 to drive the threaded rod to rotate inside the base 54, and drives the movable jaws 55 to move through the nut, clamping the workpiece between the two jaws 55. Two positioning seats 57 are symmetrically arranged on the top of the base 54. The two positioning seats 57 are respectively provided with through holes along the axial direction. The through holes on the positioning seats 57 cooperate with the positioning rod 97 of the blocking mechanism 9, which can realize the precise positioning between the auxiliary cylinder 6 and the fixture 5, and facilitate the adjustment and fixation of the position of the auxiliary cylinder 6.

[0028] Reference Figures 8 to 11 The auxiliary cylinder 6 includes a cylinder body 61, with limiting holes 611 at both ends of the cylinder body 61. These holes provide radial support and axial positioning for the pipe 71 and sleeve 81, preventing movement or displacement of the pipe 71 and sleeve 81 within the cylinder body 61 and ensuring stable operation of the suction mechanism 7 and the cleaning mechanism 8. The bottom of the cylinder body 61 has multiple through-slots 612 for air intake. Each through-slot 612 is a strip-shaped opening penetrating the bottom of the cylinder body 61 (e.g., ...). Figure 10 As shown), external metal debris is sucked into the suction mechanism 7 through the through groove 612. The opening of the through groove 612 can specifically clean the guide groove 43 on the workbench 4, which is difficult to clean.

[0029] Furthermore, guide blocks 62 are respectively provided in multiple through slots 612, and partition blocks 63 are fixedly connected between adjacent guide blocks 62. The side walls of the guide blocks 62 are arc-shaped, and the partition blocks 63 are trapezoidal in shape (e.g., Figure 11 As shown, when the auxiliary cylinder 6 moves on the worktable 4, the inclined surface of the trapezoidal partition block 63 can push the metal chips accumulated on the upper surface of the worktable 4 to both sides, so that the chips slide down into the guide grooves 43 on both sides, preventing the chips from accumulating in the processing area. The arc-shaped sidewall of the guide block 62 can scoop up the metal cutting chips deposited at the bottom of the guide groove 43, and at the same time, it can guide the airflow in the through groove 612, so that the airflow flows more smoothly to the suction nozzle 72, improving the suction efficiency and facilitating the suction mechanism 7 to clean the inside of the guide groove 43.

[0030] Reference Figure 10An air suction mechanism 7 is installed inside the auxiliary cylinder 6. The air suction mechanism 7 includes a pipe 71. Multiple suction nozzles 72 are provided at the bottom of the pipe 71 and communicate with its interior. The multiple suction nozzles 72 correspond to the positions of the through groove 612. One end of the pipe 71 is connected to the inner wall of the cylinder 61, and the other end of the pipe 71 extends to the outside of the cylinder 61 through the limiting hole 611 and is equipped with a connector 73. It should be noted that the suction nozzle 72 adopts a conical structure (the inlet cross-sectional area is larger than the outlet cross-sectional area), which can form a larger suction coverage area at the inlet and a higher airflow velocity at the outlet (the side closer to the pipe 71), thereby enhancing the suction capacity for metal debris. When an external industrial vacuum cleaner is connected to the pipe 71 through the connector 73, a continuous negative pressure is formed inside the pipe 71. The air outside the cylinder 61 carries metal debris and dust and is sucked to the suction nozzle 72 through the through groove 612, and finally discharged to the external collection device through the connector 73.

[0031] Furthermore, refer to Figure 12 and Figure 13 A cleaning mechanism 8 is fitted onto the suction mechanism 7. An embodiment of the cleaning mechanism 8 is given below: The cleaning mechanism 8 includes multiple sleeves 81, with two connecting blocks 82 fixedly connected between adjacent sleeves 81. The two connecting blocks 82 are symmetrically arranged. All sleeves 81 are mounted on the pipe 71, and all connecting blocks 82 are U-shaped. The open end of the connecting block 82 corresponds to the position of the suction nozzle 72, and the length of the opening of the connecting block 82 is greater than the height of the suction nozzle 72. It should be noted that when the multiple sleeves 81 and the connecting blocks 82 rotate, the suction nozzle 72 will pass through the U-shaped opening of the connecting block 82, thereby avoiding the suction nozzle 72 from obstructing the rotation of the sleeves 81.

[0032] In addition, bristles 83 are provided on the side walls of multiple connecting blocks 82, and the bristles 83 extend to the outside of the cylinder 61 through the through grooves 612. One end of the sleeve 81 is set in the limiting hole 611 and is rotatably connected to the cylinder 61. The other end of the sleeve 81 extends to the outside of the cylinder 61, and a knob 84 is fixedly connected to the end of the sleeve 81 away from the cylinder 61. It should be noted that when the auxiliary cylinder 6 is moved to the vicinity of the workpiece, during the milling of the metal parts, the metal debris in the guide groove 43 can be sucked away through the through grooves 612 and the suction nozzle 72. When too much accumulates, it can be cleaned. If the effect is not good, the operator can turn the knob 84 to drive multiple sleeves 81 to rotate synchronously. When the bristles 83 are inside the cylinder 61, they are kept bent by the constraint of the inner wall of the cylinder 61. When the bristles 83 rotate to the through groove 612, they are freed from the constraint of the inner wall of the cylinder 61 and the bristles 83 pop out and extend to the outside of the cylinder 61 to sweep the upper end and front end of the guide block 62, sweep away the metal debris attached to the surface of the guide block 62 and the residual metal debris in the guide groove 43, and push it back to the vicinity of the suction nozzle 72 in the through groove 612, which can achieve rapid cleaning of debris inside the guide groove 43.

[0033] Furthermore, as the brush bristles 83 rotate, they repeatedly come into contact with the guide block 62 and the inner wall of the cylinder 61, which can shake off the fine debris attached to the brush bristles 83, preventing the brush bristles 83 from losing their cleaning ability due to debris entanglement. Furthermore, after the metal parts are milled, the fixture 5 can be removed from the worktable 4, and the auxiliary cylinder 6 can be moved directly along the guide groove 43 to both ends of the worktable 4 to perform a one-time full cleaning of the entire guide groove 43. This eliminates the need for operators to hold a small brush to sweep away debris that has scattered to a distant location multiple times, reducing the labor intensity of manual cleaning and significantly improving the efficiency of equipment maintenance and cleaning.

[0034] Based on the above, and referring to Figure 14 A blocking mechanism 9 is connected to the side wall of the auxiliary cylinder 6. One embodiment of the blocking mechanism 9 is as follows: The shielding mechanism 9 includes a baffle 91, an extension seat 92 fixedly connected to the top side wall of the baffle 91, both the baffle 91 and the extension seat 92 fixedly connected to the side wall of the cylinder 61, a fixing rod 93 fixedly connected to the side wall of the extension seat 92, the fixing rod 93 being equal in length to the baffle 91, and grooves respectively provided on the baffle 91 and the fixing rod 93, a movable plate 94 slidingly passing through the baffle 91, a connecting rod 95 fixedly connected to the top of the movable plate 94 away from the baffle 91, a telescopic rod 96 fixedly connected to the upper end of the connecting rod 95, and the telescopic rod 96 slidingly passing through the fixing rod 93, a positioning rod 97 fixedly connected to the end of the telescopic rod 96 away from the fixing rod 93, the end of the positioning rod 97 away from the telescopic rod 96 extending into the positioning seat 57, and the diameter of the positioning rod 97 being equal to the diameter of the through hole opened on the positioning seat 57.

[0035] It should be noted that during the metal parts processing, the auxiliary cylinder 6 is kept near the workpiece, and the telescopic rod 96 can be pulled to slide within the fixed rod 93. At the same time, the movable plate 94 is driven to extend outward synchronously within the groove of the baffle 91. Finally, the positioning rod 97 at the end of the telescopic rod 96 is inserted into the through hole of the positioning seat 57 at the top of the fixture 5, realizing the interlocking and positioning between the auxiliary cylinder 6 and the fixture 5. At this time, the baffle 91 and the movable plate 94 together form a shield on both sides of the workpiece, effectively blocking the metal chips that fly around during the milling process, preventing them from splashing onto the operator or scattering on the ground around the machine tool, and reducing the amount of cleaning work after processing.

[0036] Furthermore, by inserting the positioning rod 97 on the positioning seat 57 and supporting the bottom of the auxiliary cylinder 6 by the guide groove 43 on the worktable 4, the fixture 5 and the auxiliary cylinder 6 can be integrated into a whole, enhancing the positional stability of the auxiliary cylinder 6 during operation. As a component with a large mass and rigidly connected to the fixture 5, the auxiliary cylinder 6 can effectively absorb some of the high-frequency vibration energy of the fixture 5 caused by the cutting force during the milling process. This is equivalent to adding a dynamic vibration absorber to the fixture 5, which can effectively suppress the resonance amplitude of the fixture 5, weaken the impact of cutting vibration on the surface quality of the workpiece, and improve the dimensional accuracy and surface finish of the milling process.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
