Description

Technical Field

[0001] The invention relates to the technical field of milling machine processing, in particular to a five-axis double-sided milling machine for processing metal materials. Background Art

[0002] The milling machine is based on the rotary motion of the tool and the feed motion of the workpiece. During the processing, the tool is installed on the spindle, and the surface of the workpiece is milled using a high-speed rotating milling cutter. The power motor is used to drive the feed motion of the milling cutter to control the processing depth, and the workpiece is fed on the worktable at the same time. The milling process is achieved by controlling the relative motion of the tool and the workpiece.

[0003] After searching, the utility model patent with publication number CN203592178U discloses a double-sided milling machine, which performs double-sided milling processing and has a simple overall structure and is easy to operate. The waste baffle can prevent iron filings and other waste materials from splashing around and being difficult to collect, thereby ensuring the hygiene of the workshop.

[0004] After the milling of both sides of the metal material is completed, the position of the workpiece needs to be changed. Since the placement of the workpiece is changed and the placement is not fixed, slight deformation is prone to occur, resulting in a decrease in the positioning accuracy of the workpiece in subsequent processing, which directly affects the accuracy and consistency of milling and affects the precision of milling. Summary of the invention

[0005] The purpose of the present invention is to provide a five-axis double-sided milling machine for metal material processing to solve the problems mentioned in the above background technology.

[0014] A discharge port is provided on one side of the workbench, and an end of the discharge port is aligned with a discharge end of a fixed station;

[0015] The two flat inner wall surfaces of the limit frame are both slidably provided with two slide plates, the two slide plates slide close to and away from each other, and a sealing strip is provided inside the slide plate, the inner wall surface of the slide plate is in contact with the surface of the feed end of the limit frame, and the inner wall surface of the limit frame away from the feed end is provided with a contact surface, and the upper surface of the limit frame is lifted and lowered with a pushing unit for pushing the metal material into the fixed station;

[0016] The pushing unit comprises a stroke cylinder, and a pushing plate is connected to the pushing end of the stroke cylinder.

[0017] A further technical improvement of the present invention is that the pushing unit also includes a top frame connected to one end of the upper surface of the limiting frame, an electric push rod is installed on the lower surface of the top frame, the pushing end of the electric push rod is connected to a T-shaped block, the stroke cylinder is installed on the lower side of the T-shaped block, and the push plate is installed on the other side of the T-shaped block.

[0018] A further technical improvement of the present invention is that the top and bottom of the outer side surface of the limit frame are provided with side grooves communicated with the limit grooves, and the outer side surface of the limit frame is installed with a screw driven by a dual-axis motor, and the outer part of the screw is matched with a sleeve plate, and the end of the sleeve plate slides through the side groove and is fixed to the corresponding slide plate.

[0019] A further technical improvement of the present invention is that: the surface of the rotating plate is provided with a bottom groove for a slide plate to open and enter.

[0020] A further technical improvement of the present invention is that a groove is provided on the outer side of the feed end of the limiting frame, a movable block is provided in the groove for limiting sliding, a spring is provided between the groove and the movable block, and an outwardly expanding inclined portion is provided on the inner edge of the movable block.

[0021] A further technical improvement of the present invention is that a stop block is provided on the upper surface of the rotating plate at the feeding end of the limiting frame, the upper part of the stop block is a slope, and the lower end of the stop block is elastically installed in the slot of the rotating plate.

[0022] A further technical improvement of the present invention is that the milling unit includes a sliding seat that rises and falls in the vertical direction along the track of the milling frame, and a driving seat for feeding different depths is slidably provided on the surface of the sliding seat, and a milling cutter is rotatably installed on the end of the driving seat, and a sleeve is provided on the outside of the driving end connected to the milling cutter, and the sleeve is fixedly connected to the driving seat.

[0023] A further technical improvement of the present invention is that a connecting ring is provided on the outside of the milling cutter, and an end of the connecting ring is connected to a fitting seat that contacts the metal material.

[0024] A further technical improvement of the present invention is that a separation chamber is provided at the bottom of the inner cavity of the driving seat, a gathering chamber is provided below the separation chamber, a filter is installed on one side of the separation chamber adjacent to the fan, and a dust inlet channel is provided on one side of the separation chamber.

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

[0026] 1. In the present invention, the metal material is limited to the limit frame, and the milling table drives the rotary station to slide horizontally to the position of the milling unit. After the milling is completed, the rotary station rotates 90 degrees clockwise, and the discharge end of the rotary station is aligned with the feed end of the fixed station. The push plate is pushed by the stroke cylinder to contact the metal material. At this time, the metal material slides along the contact surface and approaches from the discharge end to the feed end of the fixed station, and the remaining two unmilled surfaces are smoothly positioned inside the fixed station, ensuring that they are in the same placement position, avoiding repeated positioning, ensuring the accuracy and consistency of milling, and improving the milling accuracy;

[0027] 2. Since the fixed station slides to the position of the milling unit, and the rotary station is located at the edge of the workbench, the milling unit continues to mill the other two sides of the metal material, while the rotary station continues to load the material, which improves the loading efficiency, effectively utilizes the processing gap, and improves the efficiency. When the next metal material is milled, the fixed station slides to a position connected to the discharge port, and the material is transported to the discharge port through the discharge end of the fixed station to complete the transportation process after milling;

[0028] 3. When the metal material passes through the blocking block, it squeezes the blocking block, causing the blocking block to elastically enter the slot of the rotating plate. The metal material returns to its original position after leaving the blocking block, and the inner side (surface) of the blocking block limits the metal material.

[0029] 4. Since the fitting seat is in close contact with the side of the metal material first, when the milling cutter contacts the metal material, the fitting seat shrinks, pressing and sealing the milling processing position. During the milling process, the waste chips generated on the side of the metal material enter the separation chamber along the dust inlet channel due to the suction force of the fan, and fall into the gathering chamber for centralized collection after being filtered by the filter.

DETAILED DESCRIPTION

[0039] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0040] See also Figure 1-Figure 7 As shown, the present invention provides a five-axis double-sided milling machine for metal material processing, comprising a workbench 1, a milling table 6 is slidably provided on the top surface of the workbench 1 in the horizontal direction, and a U-shaped milling frame 2 is provided on the outside of the workbench 1, and milling units for processing both sides of the metal material are slidably provided on both end surfaces of the milling frame 2, and a fixed station 23 and a rotating station are respectively provided on both ends of the upper surface of the milling table 6, and the fixed station 23 and the rotating station both include a limiting frame 8 for positioning the metal material, and a rotating plate 7 is connected to the lower surface of one of the limiting frames 8, and the rotating plate 7 is rotatably installed on the middle surface of the edge of the milling table 6, and the distances between the milling units on both sides and the metal material of the corresponding surface are consistent;

[0041] When the rotating station rotates 90 degrees clockwise, the discharge end of the rotating station is aligned with the feed end of the fixed station 23;

[0042] It should be noted that the difference between the fixed station 23 and the rotary station is that the fixed station 23 is fixed, while the rotary station can rotate. When the double-sided grinding of the metal material in the rotary station is performed, after rotating 90 degrees, the other two sides of the metal material are rotated to align with the feed end of the fixed station 23, so that the metal material can enter the fixed station 23 for milling of the other two sides.

[0043] A discharge port 5 is provided on one side of the workbench 1, and the end of the discharge port 5 is aligned with the discharge end of the fixed station 23;

[0044] Two flat inner wall surfaces of the limiting frame 8 are slidably provided with two slide plates 11, the two slide plates 11 slide close to and away from each other, and a sealing strip 12 is provided inside the slide plates 11, the inner wall surface of the slide plates 11 is in contact with the feed end surface of the limiting frame 8, and the inner wall surface of the limiting frame 8 away from the feed end is provided with a contact surface 14, and the upper surface of the limiting frame 8 is provided with a pushing unit for pushing the metal material into the fixed station 23 when it is lifted;

[0045] The pushing unit comprises a stroke cylinder 20 , and a pushing plate 21 is connected to the pushing end of the stroke cylinder 20 .

[0046] When milling metal materials, the rotary station on the milling table 6 is at the edge of the workbench 1, which is the initial position. The metal material enters the corresponding limit frame 8 from the rotary station on the right side. Figure 1 and Figure 3 As shown, the metal material enters from the feeding end of the limiting frame 8, and is blocked by the upper and lower slides 11 on the two sides of the metal material to guide the entry of the metal material until the metal material fits with the contact surface 14, completing the limiting of the metal material, and then the milling table 6 drives the rotary station to slide horizontally to the position of the milling unit, which is the milling position, as shown in FIG. Figure 1 As shown; then the two slide plates 11 are opened away from each other, and the milling units on both sides are slid and adjusted in the vertical and longitudinal directions, so that the milling units enter the opened space and contact the side of the metal material, and then the two slide plates 11 are closed, and a sealed space is formed by the sealing strip 12, and the metal material is milled on both sides;

[0047] After the milling is completed, the rotary station rotates 90 degrees clockwise, and the discharge end of the rotary station is aligned with the feed end of the fixed station 23;

[0048] The pusher unit is set to rise and fall. When pushing the material, the pusher unit descends in height, and then the travel cylinder 20 pushes the push plate 21 to contact the metal material. At this time, the metal material slides along the contact surface 14 and approaches the feed end of the fixed station 23 from the discharge end, and the remaining two unmilled surfaces are smoothly positioned inside the fixed station 23;

[0049] Then the fixed station 23 and the rotary station follow the milling table 6 to slide in the horizontal direction. At this time, the fixed station 23 reaches the position of the milling unit, and the rotary station is located at the edge of the workbench 1. The other two sides of the metal material continue to be milled through the milling unit, and the rotary station continues to load the material, thereby improving the loading efficiency, effectively utilizing the processing gap, and improving the efficiency. When the next metal material is milled, the fixed station 23 slides to a position connected to the discharge port 5, and is transported to the discharge port 5 through the discharge end of the fixed station 23 to complete the transportation process after milling.

[0050] See also Figure 3 and Figure 5 As shown, the pushing unit also includes a top frame 18 connected to one end of the upper surface of the limiting frame 8, an electric push rod 22 is installed on the lower surface of the top frame 18, and the pushing end of the electric push rod 22 is connected to a T-shaped block 19. The stroke cylinder 20 is installed on the lower side of the T-shaped block 19, and the push plate 21 is installed on the other side of the T-shaped block 19.

[0051] Initially, the height of the top frame 18 is higher than the height of the slide plate 11 when it is opened, and does not affect the interference when the slide plate 11 slides open;

[0052] The pushing movement occurs after the rotating plate 7 rotates 90 degrees, that is, the two sides of the metal material are milled first, and the rotating station rotates 90 degrees clockwise. At this time, the rotating station is docked with the fixed station 23, and the T-shaped block 19 is pushed down to the middle of the side of the metal material by the electric push rod 22, and the push plate 21 is pushed by the stroke cylinder 20 to contact the side of the metal material, so that the metal material slides away from the inside of the limit frame 8.

[0053] See also Figure 3 and Figure 6 As shown, the top and bottom of the outer side of the limit frame 8 are provided with side grooves 15 communicating with the limit groove 10, and the outer side of the limit frame 8 is installed with a screw rod 25 driven by a double-axis motor, and the outer part of the screw rod 25 is sleeved with a sleeve plate 26, and the end of the sleeve plate 26 slides through the side groove 15 and is fixed to the corresponding slide plate 11;

[0054] The surface of the rotating plate 7 is provided with a bottom groove 24 for a slide plate 11 to open and enter.

[0055] The corresponding sleeve plate 26 is driven to slide in the side groove 15 by the rotation of the screw rod 25, and the two slide plates 11 are driven to slide closer or farther;

[0056] When opened, the lower slide plate 11 completely enters the bottom groove 24 without affecting the sliding out of the metal material.

[0057] See also Figure 3As shown, a groove is provided on the outer side of the feed end of the limit frame 8, a movable block 16 is provided in the groove for limiting sliding, and a spring 17 is provided between the groove and the movable block 16, and an outward-expanding inclined portion is provided on the inner edge of the movable block 16. After the metal material is guided to slide and comes into contact with the movable block 16 of the inclined portion, it enters through the feed end of the limit frame 8.

[0058] See also Figure 2 and Figure 3 As shown, a stop block 9 is provided on the upper surface of the rotating plate 7 at the feed end of the limiting frame 8, the upper part of the stop block 9 is a slope, and the lower end of the stop block 9 is elastically installed in the slot of the rotating plate 7, and the inner side surface of the stop block 9 is a straight edge.

[0059] When entering from the feeding end of the limiting frame 8, since the upper surface of the metal material fits against the top surface of the inner cavity of the limiting frame 8, the metal material squeezes the stop block 9 when passing through the stop block 9, causing the stop block 9 to elastically enter the slot of the rotating plate 7. The metal material returns to its original position after leaving the stop block 9, and is limited by the inner side edge (surface) of the stop block 9.

[0060] See also Figure 1 As shown, the milling unit includes a sliding seat 3 that rises and falls in the vertical direction along the track of the milling frame 2, and a driving seat 4 for feeding different depths is slidably provided on the surface of the sliding seat 3. A milling cutter 13 is rotatably installed at the end of the driving seat 4, and a sleeve is provided on the outside of the driving end connected to the milling cutter 13, and the sleeve is fixedly connected to the driving seat 4;

[0061] A high-precision magnetic grid is installed on the drive seat 4 to ensure accurate movement position;

[0062] In addition, the milling table 6 and the sliding seats 3 and driving seats 4 on both sides are driven by servo motors to achieve more precise motion control and accurately control the motion of each axis;

[0063] The core controller of the milling machine adopts SIEMENS S7-1212C. The CPU body has an integrated PROF I NET interface, which is used to control the servo motors in five directions of the machine tool. The CPU body has a built-in 100kHz high-speed counter (HSC) to collect pulse signals from the 5um precision magnetic grid and read the pulse number through the high-speed counter related instructions.

[0064] The program is written using structured programming. The interface input signals include target position, feed speed, start signal, current position, and the interface output signals include positioning completion and positioning error.

[0065] The operator only needs to input the dimensions in the product process drawing and complete the processing of the entire product after tool setting. No CNC programming knowledge is required, which reduces the debugging time of the product.

[0066] The fully closed-loop control of the servo motors in five directions compensates for mechanical errors and improves processing accuracy;

[0067] The milling cutter 13 mills the side of the metal material at different heights and depths by sliding in the vertical and longitudinal directions. The sleeve protects the driving end of the milling cutter 13 to avoid direct contact between the driving end and the sealing strip 12.

[0068] See also Figure 7 As shown, a connecting ring 27 is provided on the outside of the milling cutter 13, and an end of the connecting ring 27 is connected to a fitting seat 28 that contacts the metal material;

[0069] A separation chamber 29 is provided at the bottom of the inner cavity of the driving seat 4, a gathering chamber 31 is provided below the separation chamber 29, a filter 30 is installed on one side of the separation chamber 29 adjacent to the fan, and a dust inlet channel 32 is provided on one side of the separation chamber 29;

[0070] When the milling cutter 13 approaches the metal material, the fitting seat 28 is made of rubber. The fitting seat 28 first comes into close contact with the side of the metal material, and then shrinks when the milling cutter 13 comes into contact with the metal material. The fitting seat 28 presses and seals the milling processing position. During the milling process, the waste chips generated on the side of the metal material enter the separation chamber 29 along the dust inlet channel 32 due to the suction force of the fan, and fall into the gathering chamber 31 after being filtered by the filter 30, so as to facilitate regular cleaning later.

[0071] When the present invention is in use, the metal material is limited to the limit frame 8, and the milling table 6 drives the rotary station to slide horizontally to the position of the milling unit. After the milling is completed, when the rotary station rotates 90 degrees clockwise, the discharge end of the rotary station is aligned with the feed end of the fixed station 23, and the push plate 21 is pushed by the stroke cylinder 20 to contact the metal material. At this time, the metal material slides along the contact surface 14 and approaches from the discharge end to the feed end of the fixed station 23, and the remaining two unmilled surfaces are smoothly positioned inside the fixed station 23; the fixed station 23 slides to the position of the milling unit, and the rotary station is located at the edge of the workbench 1, and the other two surfaces of the metal material continue to be milled by the milling unit, while the rotary station continues to load the material, thereby improving the loading efficiency, effectively utilizing the processing gap, and improving the efficiency. When the next metal material is milled, the fixed station 23 slides to a position connected with the discharge port 5, and is transported to the discharge port 5 through the discharge end of the fixed station 23 to complete the conveying process after milling;

[0072] When the metal material passes through the stop block 9, it squeezes the stop block 9, so that the stop block 9 elastically enters the slot of the rotating plate 7. After the metal material leaves the stop block 9, it returns to its original position, and the inner side edge (surface) of the stop block 9 limits the metal material.

[0073] Since the fitting seat 28 is in close contact with the side of the metal material first, when the milling cutter 13 contacts the metal material, the fitting seat 28 shrinks, pressing and sealing the milling processing position. During the milling process, the waste chips generated on the side of the metal material enter the separation chamber 29 along the dust inlet channel 32 due to the suction force of the fan, and fall into the gathering chamber 31 for centralized collection after being filtered by the filter 30.

[0074] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
