Description

Technical Field

[0001] The present application relates to the field of machining centers, and in particular to an oblique push type fully automatic milling head storage device. Background Art

[0002] The gantry machining center is a machine tool specially designed for processing large and complex-shaped workpieces. Its main feature is that the axis of the spindle Z axis is set perpendicular to the worktable. The overall structure consists of a portal structure frame composed of double columns and a top beam. The entire portal structure frame can be moved to adjust the position of the spindle on the Y axis. At the same time, the gantry machining center will have a milling head library to accommodate different milling heads, so as to meet different processing needs by replacing the accessory milling heads.

[0003] The side milling head of the gantry machining center is usually placed on a column. The common linear transmission milling head warehouse device is generally located on the outside of the workbench. The height of the milling head warehouse device is generally higher than the workbench. At least the part of the milling head in the milling head warehouse used for connecting to the spindle after the milling head is sent out needs to be higher than the workbench to facilitate the installation of the milling head. The working steps of the traditional milling head warehouse device are: compressed air enters the cylinder that controls the switch of the milling head warehouse door to open the milling head warehouse door; then the compressed air enters the cylinder that controls the lateral movement of the milling head movable platform to move the milling head toward the spindle direction to the specified position for exchanging the milling head.

[0004] The above-mentioned milling head magazine device, since the milling head magazine is located outside the workbench, and the lateral moving mechanism also needs to be set at a position higher than the workbench, the machine tool needs sufficient space to set up the milling head magazine device, making the lateral space of the gantry machining center larger and requiring more installation space. Summary of the invention

[0005] In order to save installation space and reduce the lateral size of a machine tool, the present application provides an oblique-push type fully automatic milling head storage device.

[0006] The present application provides an oblique push type fully automatic milling head storage device adopts the following technical solution: A slant-push fully automatic milling head warehouse device comprises a milling head warehouse moving component, a milling head warehouse base body and a moving drive component, the milling head warehouse moving component comprises a milling head and a milling head bracket, a milling head warehouse space for installing the milling head warehouse moving component is provided below the machine tool worktable, and the milling head bracket is used to place the milling head; the milling head warehouse base body is partially installed in the milling head warehouse space, and the milling head warehouse base body is partially cantilevered outside the milling head warehouse space, and a mounting inclined surface is provided on the milling head warehouse base body, and the mounting inclined surface is inclined upward from the inner side of the milling head warehouse space to the outer side, and the moving drive component is installed on the mounting inclined surface to drive the milling head bracket to enter and exit the milling head warehouse space along the inclination of the mounting inclined surface.

[0007] By adopting the above technical scheme, the milling head magazine device is compounded to the inside of the machine tool under the workbench, and the milling head is moved obliquely upward along the inclination of the installation slope to the specified position for exchanging the milling head. The milling head is lifted upward while being sent out horizontally, thus overcoming the problems of large external dimensions and large space occupied by traditional automatic milling head magazine devices, utilizing the internal space of the machine tool, making full use of the equipment space, reducing the lateral dimensions of the machine tool, saving installation space, and making the overall machine tool equipment structure small and compact.

[0008] Optionally, the movable driving component includes a movable cylinder, a linear guide rail, and a slider slidably mounted on the linear guide rail, the linear guide rail is obliquely mounted along the mounting slope, the milling head bracket is mounted on the slider, and the movable cylinder drives the milling head bracket to slide on the linear guide rail.

[0009] By adopting the above technical scheme, the milling head bracket is directly moved obliquely to the corresponding position, so that the milling head has the ability to move obliquely in three-dimensional space. Only one set of mobile driving parts is needed to move the milling head to the specified position for exchanging the milling head. There are fewer action processes, a simplified structure, and it is easier to control. The moving stroke is shorter and the moving speed is faster. The head changing operation can be responded to faster, and there are fewer operating parts, which ensures the reliability and stability of automatic exchange of the milling head. The mounting inclined surface of the milling head storage base is used for the installation of linear guides and moving cylinders, which better supports the milling head bracket and ensures the stability of the oblique pushing movement process of the milling head bracket.

[0010] Optionally, the milling head warehouse moving assembly also includes a lower bracket of the milling head warehouse, and the lower bracket of the milling head warehouse is located below the overhanging part of the milling head warehouse base body. The lower bracket of the milling head warehouse includes a horizontal plate and a vertical plate that are perpendicular to each other at 90 degrees. The horizontal plate abuts the milling head warehouse base body, and connecting plates are protruding on both sides of the milling head warehouse base body. The connecting plates are fixed to the horizontal plates with screws, and the vertical plates are fixed to the machine tool. The lower bracket of the milling head warehouse abuts and supports the overhanging part of the milling head warehouse base body.

[0011] By adopting the above technical scheme, the overhanging part of the milling head warehouse base body is supported by the lower bracket of the milling head warehouse, so that the milling head warehouse base body is sufficiently stable, the sliding movement of the milling head bracket on the milling head warehouse base body is more stable, and the whole milling head replacement process is smoother. The lower bracket of the milling head warehouse is composed of a horizontal plate and a vertical plate that are perpendicular to each other at 90 degrees, and the connecting plates on both sides of the milling head warehouse base body make the connection between the milling head warehouse base body and the horizontal plate more convenient, and the screws can be driven in from top to bottom.

[0012] Optionally, there are two linear guides, which are arranged on both sides of the mobile cylinder. The milling head bracket includes a horizontal part and an inclined part. The horizontal part is for placing the milling head, and the inclined part is fixed to the slider of the linear guide. The two side parts of the inclined part protrude and are located on both sides of the horizontal part and are integrated with the horizontal part, and the horizontal part is spaced apart from the track part of the linear guide. The lower side wall of the horizontal part is protruding with a milling head library connecting plate for connecting the front shaft end of the mobile cylinder.

[0013] By adopting the above technical scheme, the two linear guide rails not only guide the sliding of the milling head bracket but also support the milling head bracket, and the mobile cylinder supports the middle part of the milling head bracket, so that the sliding process of the milling head bracket is smoother. The milling head bracket is provided with a horizontal part and an inclined part, which is convenient for the placement of the milling head. The milling head on the horizontal part can be placed more stably. At the same time, the inclined part is conducive to the connection with the linear guide rails, and the protrusions on both sides of the inclined part and the horizontal position ensure that the milling head bracket will not be insufficiently supported due to the setting of the horizontal part, thereby reducing the support requirements of the mobile cylinder for the milling head library base body, and the milling head library connecting plate facilitates the connection between the milling head library bracket and the mobile cylinder.

[0014] Optionally, it also includes a milling head warehouse protection component, which includes a front baffle and a protective cover assembly, the front baffle is installed on the milling head bracket and moves with the milling head bracket, when the milling head bracket is retracted into the milling head warehouse space, the front baffle closes the entrance and exit of the milling head warehouse space, the protective cover assembly is installed on the milling head warehouse base body and the milling head bracket, and the protective cover assembly always wraps the exposed part of the installation bevel on the milling head warehouse base body located on the outside of the milling head bracket.

[0015] By adopting the above technical scheme, the milling head library protection component closes and protects the milling head library space through the front baffle. When the milling head library moving component is located in the milling head library space, it effectively prevents the milling head from contacting the machine tool cooling water and chips, ensuring the safety of the milling head placed in the milling head library space. The protective cover assembly closes and protects the linear guide part, further improving the waterproof and chip proof performance of the milling head library device. The front baffle slides with the sliding of the milling head library bracket, so that the milling head bracket enters and exits the milling head library space and the opening process of the milling head library space is uniformly driven. Only one set of mobile drive parts is needed to simultaneously realize the opening of the front baffle, moving the milling head bracket to the outside of the milling head library space, and lifting the milling head to the specified position for exchanging milling heads while moving, thereby simplifying the drive system of the machine tool and improving the efficiency of changing milling heads.

[0016] Optionally, the protective cover assembly includes a first protective cover and a second protective cover, the first protective cover is in an inverted L-shape and is divided into a sliding portion and a rotating portion that are perpendicular to each other, the first protective cover slidingly cooperates with the second protective cover through the sliding portion, the first protective cover is rotatably connected to the milling head storage base body through the rotating portion, and the second protective cover is rotatably connected to the milling head bracket on the side away from the first protective cover.

[0017] By adopting the above-mentioned technical scheme, the protective cover assembly can be expanded and retracted through the rotational movement of the first protective cover and the second protective cover and the relative sliding movement between the first protective cover and the second protective cover under the push of the milling head bracket. No matter where the milling head bracket slides to, the protective cover assembly can maintain its protective effect on the milling head base body and the linear slide rail.

[0018] Optionally, the milling head library protection assembly also includes a bed protection cover, which is installed on the machine tool body and cantilevered toward the front baffle. An abutting outer edge is protruding on the outer side of the bed protection cover, and the abutting outer edge is used for the front baffle to abut and achieve protection.

[0019] By adopting the above technical scheme, the setting of the bed protective cover allows the milling head bracket to be installed in a position further forward of the milling head library base, further reducing the sliding stroke of the milling head bracket, reducing the size of the protective cover assembly, and overall improving the response speed of the equipment, reducing the structural complexity, and reducing the size and space requirements. At the same time, the setting of the bed protective cover also makes the waterproof and chip-proof performance better, and liquids and chips are less likely to enter the milling head library space along the vertical surface. The bed protective cover provides a more tortuous surface to guide the cooling water to flow away, and the setting of the abutting outer edge increases the contact area between the bed protective cover and the front baffle, further reducing the entry of cooling water and chips, and the abutment process between the bed protective cover and the front baffle is less likely to deform, and the contact process is softer.

[0020] Optionally, the outer edge of the front baffle is provided with a protective outer edge protruding toward the machine tool body and forming a protective groove for the abutting outer edge to be placed in, and a movable gap is formed between the protective outer edge and the abutting outer edge.

[0021] By adopting the above technical solution, the protective groove on the front baffle further improves the water and chip prevention performance, and the existence of the moving gap makes the movement process of the front baffle smoother and less prone to interference.

[0022] Optionally, the milling head warehouse protection assembly also includes a front lower sheet metal cover, which is installed on the milling head warehouse base body, and the upper part of the front lower sheet metal cover is spaced apart from the protection cover assembly to form a moving gap, and the lower part of the front lower sheet metal cover extends obliquely toward the machine tool body over the milling head warehouse base body.

[0023] By adopting the above technical solution, the front lower end sheet metal cover is provided to protect the lower part of the milling head magazine base body, and cooperates with the protective cover assembly and the front baffle to achieve a more comprehensive protection effect and reduce the entry of coolant and chips into the milling head magazine device.

[0024] Optionally, it also includes an automatic safety control component for a milling head warehouse, and the automatic installation control component for the milling head warehouse includes a front proximity switch, a rear proximity switch, a proximity switch bracket, a rear impact block for the milling head warehouse and a proximity switch signal block. There are two proximity switch brackets, and the two proximity switch brackets are spaced apart along the base of the milling head warehouse. The front proximity switch and the rear proximity switch are respectively installed on one of the proximity switch brackets in a one-to-one correspondence, and the proximity switch signal block is installed on the milling head bracket; the rear impact block of the milling head warehouse is installed at the rear end of the milling head warehouse base and corresponds to the milling head bracket retracting to the extreme position of the milling head warehouse space.

[0025] By adopting the above technical scheme, the sliding stroke of the milling head bracket is controlled by the front proximity switch, the rear proximity switch and the proximity switch signal block, so that the milling head can be better sent to the corresponding position for head changing and the milling head returns to the milling head library space. The setting of the rear impact block of the milling head library ensures the safety of the milling head bracket sliding reset beyond the limit, limits the maximum limit of the milling head bracket sliding reset, and plays a good protective role on the protective cover assembly, the front baffle and the bed protective cover.

[0026] To sum up, integrating the milling head library device into the interior of the machine tool overcomes the problems of large external dimensions and large space occupied by the traditional automatic milling head library device, uses the internal space of the machine tool, makes full use of the equipment space, reduces the lateral dimensions of the machine tool, saves installation space, and the overall machine tool equipment structure is small and compact. The milling head bracket is directly moved obliquely to the corresponding position, and has the ability to move obliquely in three-dimensional space. The action process is fewer and easier to control. The moving stroke is shorter and the moving speed is faster. The head changing operation can be responded to faster, and there are fewer operating parts, which ensures the reliability and stability of automatic exchange of milling heads.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] The embodiment of the present application discloses an oblique push type fully automatic milling head storage device.

[0036] Reference Figure 1 and Figure 2 A slant-push fully automatic milling head warehouse device includes a milling head warehouse moving component 1, a milling head warehouse protection component 2 and a milling head warehouse automatic safety control component. The milling head warehouse moving component 1 is used for the in and out sliding of the milling head to send the milling head to the corresponding position. The milling head warehouse protection component 2 is used for full-state protection during the operation of the milling head warehouse moving component 1. The milling head warehouse automatic safety control component is used to ensure the safety and stability of the milling head warehouse moving component 1 during the operation.

[0037] A milling head warehouse space 4 for installing a milling head warehouse moving component 1 is provided under the machine tool worktable. The milling head warehouse moving component 1 transports the milling head at an angle to the corresponding milling head changing position for milling head changing operation. Specifically, the milling head warehouse moving component 1 includes a milling head 11, a milling head warehouse positioning component 12, a milling head warehouse lower bracket 13, a milling head bracket 14 and a moving driving component for driving the milling head bracket 14 to move. The milling head bracket 14 is used to place the milling head 11, and the milling head warehouse positioning component 12 is installed on the milling head bracket 14 to position the milling head 11 firmly on the milling head bracket 14.

[0038] Reference Figure 1 and Figure 3 The milling head bracket 14 enters and exits the milling head storage space 4 under the drive of the mobile driving member, and the milling head bracket 14 moves out of the milling head storage space 4 and drives the upper part of the milling head 11 to be lifted above the machine tool worktable. The specific implementation of the mobile driving member in this embodiment is as follows: the mobile driving member includes a milling head storage seat body 151, a linear guide rail 152 and a mobile cylinder 153. The mobile storage seat body is provided for the installation of the linear guide rail 152 and the mobile cylinder 153. The milling head storage seat body 151 is partially installed in the milling head storage space 4 and is connected to the machine tool bed assembly by screws. The milling head storage seat body 151 is partially cantilevered outside the milling head storage space 4. The cross-section of the milling head storage seat body 151 is triangular and the upper side wall is set to be an installation inclined surface 1511 for the installation of the linear guide rail 152 and the mobile cylinder 153. The installation inclined surface 1511 is arranged to be inclined upward from the inner side of the milling head storage space 4 to the outer side. The outward side wall of the body 151 is inclined in the vertical downward direction toward the milling head warehouse space 4. The lower bracket 13 of the milling head warehouse is used to support the overhanging part of the milling head warehouse base body 151. The lower bracket 13 of the milling head warehouse is located below the overhanging part of the milling head warehouse base body 151. The lower bracket 13 of the milling head warehouse includes a horizontal plate 131 and a vertical plate 132 which are perpendicular to each other at 90 degrees, and reinforcing ribs 133 for enhancing the supporting strength. The horizontal plate 131 abuts the milling head warehouse base body 151, and connecting plates 1512 are protruding on both sides of the milling head warehouse base body 151. The connecting plates 1512 are fixed to the horizontal plates 131 with screws, and the vertical plates 132 are fixed to the machine tool with screws. The lower bracket 13 of the milling head warehouse abuts and supports the overhanging part of the milling head warehouse base body 151, wherein the reinforcing ribs 133 are located in the middle of the horizontal plate 131 and the vertical plate 132, so as to facilitate the connection operation between the connecting plate 1512 and the horizontal plate 131.

[0039] The movable cylinder 153 is installed in the middle of the mounting bevel 1511. The movable cylinder 153 is fixed to the milling head base body 151 by screws through the cylinder front bracket 1531 and the cylinder rear bracket 1532. There are two linear guide rails 152. The two linear guide rails 152 are fixed on the mounting bevel 1511 by screws and are arranged on both sides of the movable cylinder 153. The milling head bracket 14 is fixed to the sliders of the two linear guide rails 152 by screws on both sides.

[0040] Specifically, the milling head bracket 14 includes a horizontal portion 141 and an inclined portion 142 located at the bottom and a protective portion 143 located at the top. The horizontal portion 141 is for placing the milling head 11, and the milling head library positioning member 12 is also installed on the horizontal portion 141. The inclined portion 142 is inclined and extended downward relative to the horizontal portion 141. At the same time, the inclined portion 142 is directly fixed to the slider of the linear guide 152, that is, the inclined surface of the inclined portion 142 is consistent with the sliding direction of the milling head bracket 14, and the two side parts of the inclined portion 142 protrude on both sides of the horizontal portion 141 and are integrated with the horizontal portion 141, thereby increasing the area where the slider of the linear guide 152 supports the milling head bracket 14 to the position of the horizontal portion 141, and better supporting the horizontal portion 141. The milling head 11 on the horizontal part 141 is arranged at an interval with the track part of the linear guide 152, so that there is enough space on the lower side wall of the horizontal part 141 to protrude the milling head library connecting plate 144 for connecting the front axle end of the moving cylinder 153 to realize triangular positioning and support. The milling head library connecting plate 144 is connected to the front axle end of the moving cylinder 153 by bolts, and the protective part 143 protrudes above the horizontal part 141 and the inclined part 142 to limit the milling head 11 on the horizontal part 141, protect the milling head 11, and limit the milling head 11 from falling sideways and detaching from the milling head bracket 14, wherein the cross-section of the part of the protective part 143 located at the inclined part 142 is triangular, thereby improving the structural strength of the protective part 143.

[0041] Reference Figure 3 and Figure 4 The milling head warehouse protection component 2 includes a front baffle 21, a bed protection cover 22, a protection cover assembly 23 and a front lower end sheet metal cover 24. The front baffle 21 is installed on the milling head bracket 14 and moves with the milling head bracket 14. The bed protection cover 22 is installed on the machine tool body. When the milling head bracket 14 is retracted into the milling head warehouse space 4, the front baffle 21 cooperates with the bed protection cover 22 to close the entrance and exit of the milling head warehouse space 4. The bed protection cover 22 is installed on the machine tool body. One side of the bed protection cover 22 is fixed to the machine tool bed, and the other side is cantilevered toward the front baffle 21. An abutting outer edge 221 is protruded from the outer side of the body protective cover 22, and the abutting outer edge 221 surrounds the outer edge of the bed body protective cover 22 to form an inverted U-shaped plate. The abutting outer edge 221 is abutted by the front baffle plate 21 to achieve protection, and the outer edge of the front baffle plate 21 protrudes toward the machine tool body and forms a protective groove 211 for the abutting outer edge 221 to be placed. A moving gap is formed between the protective outer edge and the abutting outer edge 221 to facilitate the abutting outer edge 221 to enter and exit the protective groove 211 when the front baffle plate 21 moves with the milling head bracket 14.

[0042] Reference Figure 4 and Figure 5The protective cover assembly 23 is installed on the milling head storage base body 151 and the milling head bracket 14. The protective cover assembly 23 always wraps the exposed part of the installation inclined surface 1511 on the milling head storage base body 151 located on the outside of the milling head bracket 14. The protective cover assembly 23 flips and retracts to maintain a protective state when the milling head bracket 14 slides. Specifically: the protective cover assembly 23 includes a first protective cover 231 and a second protective cover 232. The first protective cover 231 is in an inverted L shape and is divided into a sliding part 2311 and a rotating part 2312 that are perpendicular to each other. The first protective cover 231 slides with the second protective cover 232 through the sliding part 2311. The first The protective cover 231 is rotatably connected to the milling head storage base body 151 through the rotating part 2312, and the second protective cover 232 is rotatably connected to the milling head bracket 14 on the side away from the first protective cover 231. In order to provide for the rotatable connection of the first protective cover 231, a front rotating shaft bracket 25 is fixedly installed on the outward inclined side wall of the milling head storage base body 151, and the front rotating shaft bracket 25 is rotatably connected to the first protective cover 231 through a rotating shaft. In order to provide for the rotatable connection of the second protective cover 232, a rear rotating shaft support seat 26 is fixedly installed on the outward side of the milling head bracket 14, and the rear rotating shaft support seat 26 is rotatably connected to the second protective cover 232 through a rotating shaft.

[0043] Reference Figure 4 and Figure 6 In order to ensure the sliding limit and sealing between the first protective cover 231 and the second protective cover 232, the first protective cover 231 is located on the inner side of the second protective cover 232, and a protective cover sealing strip 27 is provided on the inner side of the second protective cover 232 away from the milling head bracket 14. The sealing is maintained by the cooperation between the protective cover sealing strip 27 and the outer wall of the first protective cover 231. A protective cover limiting plate 28 is provided on the outer wall at the end of the first protective cover 231. The sliding limit of the protective cover assembly 23 is performed by the cooperation between the protective cover limiting plate 28 and the protective cover sealing strip 27 and its mounting structure. Due to the elasticity of the protective cover sealing strip 27, the limiting process also has elastic limiting, which is less likely to be damaged.

[0044] Reference Figure 4 and Figure 5When the protective cover assembly 23 is in the expanded state, the first protective cover 231 is also inclined in the direction from the second protective cover 232, but the inclination direction is opposite to the inclination and sliding direction of the milling head bracket 14, that is, it is inclined downward, the first protective cover 231 is at the bottom, and the second protective cover 232 is at the top. When the protective cover assembly 23 is in the retracted state, the overall protective cover assembly 23 is L-shaped, and the sliding portion 2311 of the first protective cover 231 is retracted into the second protective cover 232. In order to maintain the protection of the area between the protective cover assembly 23 and the front baffle plate 21, the front baffle plate 21 is close to the lower part of the protective cover assembly 23, and the second protective cover 232 protrudes outward to wrap the part, and the upper side wall of the protruding part of the lower part of the front baffle plate 21 is inclined to better guide the liquid to flow away, and the upper side wall of the second protective cover 232 located in the front baffle plate 21 is protruding with a blocking protrusion 233 to further block it. At the same time, the interval and space between the front baffle plate 21 and the second protective cover 232 are sufficient for the flipping and retraction of the second protective cover 232.

[0045] The front lower end sheet metal cover 24 is installed on the milling head storage base body 151, and the upper part of the front lower end sheet metal cover 24 is spaced apart from the protective cover assembly 23 to form a moving gap. The position of the front lower end sheet metal cover 24 can be adjusted up and down to control the size of the moving gap. The lower part of the front lower end sheet metal cover 24 passes over the milling head storage base body 151 and extends obliquely toward the machine tool body, and the lower part extends away from the machine tool body.

[0046] The above-mentioned front baffle 21 wraps the protective cover assembly 23 in the width direction, and the protective cover assembly 23 wraps the front lower end sheet metal cover 24 in the width direction, and the outer side of the front lower end sheet metal cover 24 is closer to the machine tool body relative to the protective cover assembly 23, so that the entire milling head library protection component 2 is gradually reduced from top to bottom, thereby better ensuring the protection performance.

[0047] Reference Figure 1 and Figure 2 The automatic installation control component of the milling head library includes a front proximity switch 31, a rear proximity switch 32, a proximity switch bracket 33, a rear impact block 34 of the milling head library and a proximity switch signal block 35. There are two proximity switch brackets 33, and the two proximity switch brackets 33 are arranged at intervals along the base of the milling head library. The front proximity switch 31 and the rear proximity switch 32 are respectively installed on a proximity switch bracket 33 in a one-to-one correspondence. The proximity switch signal block 35 is installed on the milling head bracket 14. The front proximity switch 31 cooperates with the proximity switch signal block 35 to correspond to the milling head 11 reaching the head changing position. It can be adjusted to keep the milling head bracket 14 from providing a correct output signal when it reaches the head changing position, and execute automatic control of the exchange of the milling head 11. The rear proximity switch 32 cooperates with the proximity switch signal block 35 to correspond to the milling head 11 returning to the milling head library space 4; the rear impact block 34 of the milling head library is installed at the rear end of the milling head library seat 151 and corresponds to the milling head bracket 14 retracting to the extreme position of the milling head library space 4.

[0048] The implementation principle of an oblique-push fully-automatic milling head storage device in an embodiment of the present application is as follows: after the compressed air enters the moving cylinder 153, the milling head bracket 14 is pushed by the piston rod to move obliquely upward along the linear guide rail 152 to the specified position for exchanging the milling head. Under the push of the milling head bracket 14, the protective cover assembly 23 rotates and contracts the protective cover to maintain the protective state, and the front baffle 21 moves with the milling head bracket 14 to open the top of the milling head 11. The front proximity switch 31 and the switch signal block are close to outputting a signal in place to the system to control the milling head changing program.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
