Embodiments provide a milling device, which can be used for milling grooves of some workpieces, for example, milling grooves of some cylindrical workpieces.

As shown in fig. 1 to 3, the milling apparatus comprises a frame 1, a clamping unit 602 and at least two sets of milling units. Wherein, the frame 1 can be a vertical structure, and the side view of the frame 1 can be an L-like structure. The clamping unit 602 and the at least two sets of milling units are both mounted on the frame 1.

Specifically, the milling units are mounted on a vertical structure of the frame 1, and the at least two groups of milling groove units are distributed annularly. When the milling machine works, at least two groups of milling units can simultaneously mill a workpiece; therefore, the milling equipment can process at least two groups of slotted holes on the workpiece so as to improve the processing efficiency of the milling equipment.

The clamping unit 602 is slidably mounted on the horizontal structure of the frame 1, and the clamping unit 602 is used for clamping a workpiece. Meanwhile, the sliding direction of the clamping unit 602 is arranged along the axis of the ring surrounded by the milling unit. In operation, the clamping unit 602 can drive the workpiece to slide synchronously, so that the workpiece can move relative to the milling unit. On the one hand, the workpiece can be moved closer to or further away from the milling unit, and on the other hand, the milling unit can be moved over a milling movement distance of a certain length on the workpiece, so as to machine a groove of a certain length, the length direction of which coincides with the sliding direction of the clamping unit 602.

The traditional milling equipment can only process one slotted hole at a time, and the milling equipment provided by the application can mill at least two groups of slotted holes simultaneously when milling a workpiece. Therefore, compared with the traditional milling equipment, the milling equipment provided by the application has higher working efficiency so as to improve the production efficiency.

Example two

In the embodiment, a milling device is provided, and it can be understood that the embodiment is a further improvement on the first embodiment.

As shown in fig. 1 to 4, the frame 1 includes a housing 11, a mounting frame 12, and a work table 14. Wherein, the middle part of the shell 11 is provided with a communicating hole to communicate with the two sides of the shell 11; thus, the outer shape of the housing 11 is a ring-like structure; the inside of the ring-like structure of the shell 11 is a hollow structure. The mounting frame 12 is fixedly mounted inside the housing 11. Correspondingly, the middle part of the mounting rack 12 is also provided with a communicating hole which is matched with the communicating hole in the middle part of the shell 11 in the direction; the mounting frame 12 is also of a ring-like structure, and is adapted to the shape of the housing 11. The work table 14 is arranged through the communication hole of the housing 11, and one end of the work table 14 extends to the outside of the housing 11; the work table 14 is fixedly connected to the housing 11. In the embodiment, support legs 15 are provided below the frame 1 and the work table 14.

The milling unit is located inside the housing 11 and is mounted on a mounting frame 12. Specifically, the milling units are distributed around the communication holes of the mounting frame 12 and are distributed annularly. The plurality of through holes 121 are distributed on the frame body of the mounting frame 12, so that the manufacturing cost of the mounting frame 12 is reduced, and the heat dissipation of the milling unit can be accelerated.

The clamp unit 602 is slidably mounted on the table 14, and the clamp unit 602 slides in the extending direction of the table 14. In use, the clamping unit 602 is used to move a workpiece on the work table 14; when the workpiece is milled, the clamping unit 602 drives the workpiece to move in a direction close to the housing 11, so that the workpiece is conveyed to the position of the milling unit, which is convenient for the milling unit to perform milling operation on the workpiece. After the machining is completed, the clamping unit 602 drives the workpiece to move in the direction away from the housing 11, and moves to the end of the working platform 14 located outside the housing 11, so that the worker can conveniently disassemble and assemble the workpiece.

In some embodiments, the frame 1 further includes two supporting platforms 13, the two supporting platforms 13 are respectively disposed on two sides of the working platform 14, and the supporting platforms 13 are correspondingly disposed at one end of the working platform 14 located outside the housing 11. The support platform 13 is used for a worker to stand, so that the worker can mount or dismount the workpiece to or from the clamp unit 602.

It is understood that the milling device further comprises a master control mechanism, and the work of the milling device is controlled by the master control mechanism so as to realize the automation of the milling device. The milling unit and the clamping unit 602 are both electrically connected with the main control mechanism. The working personnel can also adjust the working parameters of the milling equipment by operating the main control mechanism. In some specific embodiments, the main control mechanism is disposed in the control box 7 on one side of the housing 11.

As shown in fig. 3, in some specific embodiments, the milling unit may be a slot milling unit 3 or a hole milling unit 4. The groove milling unit 3 is used for performing groove milling on the workpiece, and the hole milling unit 4 is used for performing hole milling on the workpiece. In the embodiment, the milling device comprises both the slot milling unit 3 and the hole milling unit 4. The number of the milling groove units 3 can be set to one group, two groups, three groups, four groups, six groups and the like. The number of the hole milling units 4 can be set to one group, two groups, four groups, five groups, six groups, etc.

Of course, in other embodiments, the milling device may be provided with only the slot-milling unit 3, or may also be provided with only the hole-milling unit 4.

In this embodiment, the milling apparatus includes four sets of slot milling units 3, namely a first slot milling unit 31, a second slot milling unit 32, a third slot milling unit 33, and a fourth slot milling unit 34, and a set of hole milling units 4. In the embodiment, four sets of milling groove units 3 are arranged around the communication hole of the housing 11; and the four groups of milling groove units 3 are uniformly distributed at intervals. The first groove milling unit 31 and the third groove milling unit 33 are arranged oppositely; the second groove milling unit 32 and the fourth groove milling unit 34 are arranged oppositely, and the third groove milling unit 33 and the fourth groove milling unit 34 are respectively arranged at two sides of the operating platform 14 and are symmetrically arranged. The hole milling unit 4 is arranged between the first slot milling unit 31 and the second slot milling unit 32.

In other embodiments, the positions of the hole milling units 4 and the four sets of groove milling units 3 can be adjusted according to requirements.

When the four-group groove milling unit 3 works, the four-group groove milling unit can simultaneously perform groove milling on a workpiece. Thus, for some cylindrical workpieces with the number of grooves being a multiple of four, four grooves can be machined at a time. Compared with the prior art, the three-quarter operation time can be reduced, and the working efficiency of the milling equipment is improved. In the meantime, the hole milling unit 4 can also perform hole milling on the corresponding position of the workpiece, thereby further saving the time for processing the workpiece.

Of course, for some special cylindrical workpieces, one, two or three groups of milling groove units can be opened to perform simultaneous operation, and the operation can be specifically selected according to needs.

In the embodiment, the four sets of slot milling units 3 and hole milling units 4 have the same structure, and for example, one set of slot milling unit 3 is taken as an example for detailed description.

As shown in fig. 3, 5 and 6, the milling unit 3 includes a milling cutter 301, a first driving member 303 and a moving assembly 304. The first driving member 303 is used for driving the milling cutter 301 to rotate, so as to achieve a milling function. The moving assembly 304 is mounted on the mounting frame 12, and the milling cutter 301 and the first drive member 303 are mounted on the moving assembly 304. The moving assembly 304 can drive the milling cutter 301 to move in two dimensions; the two dimensions are perpendicular to each other, and both dimensions are perpendicular to the axis of the ring formed by the milling units, i.e. both dimensions are perpendicular to the sliding direction of the clamping unit 602.

Specifically, the moving assembly 304 can drive the milling cutter 301 to move telescopically, so that the milling cutter 301 is close to or far away from the workpiece; it is understood that the moving assembly 304 may move the milling cutter 301 along the axial direction of the milling cutter 301. Meanwhile, the moving assembly 304 can drive the milling cutter 301 to move in the direction perpendicular to the axis of the milling cutter 301; it will be appreciated that the moving assembly 304 may move the milling cutter 301 along the width of the groove on the workpiece to machine the groove with a desired width. Of course, the length of the slot in the workpiece is set along the length of the cylindrical workpiece; the width of the groove is set along the circumferential direction of the cylindrical workpiece.

Correspondingly, a through hole through which the milling cutter 301 passes is formed in the housing 11, so that the milling cutter 301 extends into the communication hole of the housing 11 from the inside of the housing 11, and the milling cutter 301 can be conveniently contacted with a workpiece to perform groove milling operation on the workpiece. It will be appreciated that the size of the via is such as to accommodate the movement requirements of the milling cutter 301 so as to avoid interfering with the proper operation of the milling slot unit 3.

Further, the moving assembly 304 includes a first sliding plate 3041, a second sliding plate 3042, and a mounting plate 3044. The milling cutter 301 and the first driver 303 are mounted on the first sliding plate 3041; the first sliding plate 3041 is slidably mounted on the second sliding plate 3042; the second sliding plate 3042 is slidably mounted on the mounting plate 3044; the mounting plate 3044 is fixedly mounted on the mounting bracket 12. The sliding direction of the first sliding plate 3041 is perpendicular to the sliding direction of the second sliding plate 3042.

In particular embodiments, the second sliding plate 3042 has a length extending perpendicular to the length extending of the mounting plate 3044. The second sliding plate 3042 has a length extending direction parallel to the axis of the milling cutter 301. The mounting plate 3044 has a length extending in a direction perpendicular to the axis of the milling cutter 301.

The slot milling unit 3 further comprises a first mounting block 302, and the milling cutter 301 is mounted on the first sliding plate 3041 through the first mounting block 302. Specifically, the first mounting base 302 is fixedly mounted on the first sliding plate 3041; one end of the first mounting seat 302, which is close to the through hole of the housing 11, is provided with a chuck 302a for clamping the milling cutter 301, and the chuck 302a is rotatably mounted on the first mounting seat 302. In use, the milling cutter 301 can be fixedly mounted on the collet 302a by a worker, thereby rotatably mounting the milling cutter 301 on the first mounting base 302. The first driving member 303 is fixedly mounted on an end of the first mounting base 302 away from the chuck 302 a; the output shaft of the first driver 303 is connected to the collet 302 a. In some embodiments, the first driving member 303 is a motor; the output shaft of the first driving member 303 can be fixedly connected with the chuck 302a through a connecting rod (not shown in the figure); the connecting rod is located inside the first mount 302. Therefore, the first driving member 303 drives the chuck 302a to rotate, and further drives the milling cutter 301 to rotate, so as to achieve the milling function.

A first slide rail 3042a is provided on a side of the second sliding plate 3042 adjacent to the first sliding plate 3041; accordingly, a first sliding block 3041a is disposed on a side of the first sliding plate 3041 away from the first mounting base 302. The first sliding block 3041a is slidably connected to the first sliding rail 3042a so as to slidably mount the first sliding plate 3041 on the second sliding plate 3042. The first slide rail 3042a is disposed along the length direction of the second slide plate 3042, and is parallel to the axial direction of the milling cutter 301.

The moving assembly 304 further includes a third driving member 3043, and the third driving member 3043 is fixedly mounted on an end of the second sliding plate 3042 away from the via hole on the housing 11. The third driving member 3043 is used to drive the first sliding plate 3041 to slide relative to the second sliding plate 3042.

In some embodiments, the third driving member 3043 can be a motor; the output shaft of the third driving member 3043 is fixedly connected with a first screw rod (not shown in the figure); the extending direction of the first lead screw is the same as the extending direction of the first slide rail 3042 a; the first lead screw is located inside the second sliding plate 3042. A first nut bushing (not shown) engaged with the first lead screw is disposed on a side of the first sliding plate 3041 adjacent to the second sliding plate 3042. When the third driving element 3043 drives the first screw rod to rotate, the first sliding plate 3041 slides along the first sliding rail 3042a under the matching action of the first screw rod and the first nut sleeve.

In other embodiments, the third driving member 3043 can also be driven by a pneumatic cylinder, a hydraulic cylinder, or the like; the piston rod of the third driver 3043 is fixedly connected to the first sliding plate 3041. Thereby, the first sliding plate 3041 is slid by the third driving member 3043.

In an embodiment, the moving assembly 304 further includes a first drag chain 3046, and the moving direction of the first drag chain 3046 is consistent with the sliding direction of the first sliding plate 3041. The first drag chain 3046 is used to protect the cables connected to the first drive member 303.

Two ends of the first sliding rail 3042a are respectively sleeved with a section of elastic protection sleeve 2 to protect the first sliding rail 3042a and the first screw rod inside the second sliding plate 3042. Correspondingly, two end portions of the second sliding plate 3042 are respectively provided with a first limiting plate 3042c for limiting and abutting against the elastic protection sleeve 2; one end of the elastic protection sleeve 2 away from the first stop plate 3042c abuts against the corresponding side of the first sliding plate 3041. In the working process, the sundries can be prevented from entering the second sliding plate 3042 and falling onto the first sliding rail 3042a, and further the sundries can be prevented from affecting the sliding fit between the first sliding block 3041a and the first sliding rail 3042a and the transmission between the first lead screw and the first nut sleeve. In some specific embodiments, the elastic protection sleeve 2 may be made of an organ sheet metal, and may extend and contract along with the sliding of the first sliding plate 3041.

In other embodiments, the elastic protection sleeve 2 may also be provided with other protection shell structures with elastic expansion to prevent the impurities from entering the inside of the second sliding plate 3042.

Further, a second slide rail 3044a is disposed on the mounting plate 3044 near the second sliding plate 3042, and the second slide rail 3044a is perpendicular to the first slide rail 3042 a. Accordingly, a second sliding block 3042b is disposed on one side of the second sliding plate 3042, which is close to the mounting plate 3044, and the second sliding block 3042b is slidably disposed on the second sliding rail 3044 a. Thereby, the sliding mounting of the second sliding plate 3042 on the mounting plate 3044 is achieved.

The moving assembly 304 further includes a fourth drive 3045 for driving the second sliding plate 3042 to slide relative to the mounting plate 3044; the fourth drive 3045 is fixedly mounted to one end of the mounting plate 3044. In some embodiments, the fourth driving member 3045 can be an electric motor; an output shaft of the fourth driving member 3045 is fixedly connected with a second lead screw (not shown in the figure), which is located inside the mounting plate 3044; and the second lead screw is disposed in parallel with the second slide rail 3044 a. A corresponding second nut sleeve is arranged on one side of the second sliding plate 3042 close to the mounting plate 3044, and the second nut sleeve is connected with the second lead screw in a matching manner. Thus, the fourth driving member 3045 drives the second screw rod to rotate, so as to drive the second sliding plate 3042 to slide relative to the mounting plate 3044.

In other embodiments, the fourth driving member 3045 can also be driven by a pneumatic cylinder, a hydraulic cylinder, or the like, to drive the second sliding plate 3042 to slide along the second sliding rail 3044 a.

Two ends of the second slide rail 3044a are also sleeved with elastic protection sleeves 2 to protect the second slide rail 3044a and the second screw rod and the second nut sleeve located in the mounting plate 3044. The interference of the impurities on the sliding fit between the second slide block 3042b and the second slide rail 3044a and the transmission function between the second screw rod and the second nut sleeve are avoided. Correspondingly, the two ends of the mounting plate 3044 are both provided with second limiting plates 3044b for limiting the elastic protection sleeve 2; one end of the elastic protection sleeve 2 abuts against the second stop plate 3044b for limiting, and the other end abuts against the corresponding side of the second sliding plate 3042.

In an embodiment, the movement assembly 304 further comprises a second tow chain 3047; the moving direction of the second drag chain 3047 is consistent with the sliding direction of the second sliding plate 3042; the second drag chain 3047 is used to protect a cable connected to the third driving element 3043.

In an embodiment, the first driving member 303, the third driving member 3043, and the fourth driving member 3045 are electrically connected to the main control mechanism. The master control mechanism can control the operation of the first driving member 303, the third driving member 3043 and the fourth driving member 3045 in each group of milling slot units individually. Of course, in some embodiments, the operator may select the model of the milling cutter 301 in each group of milling groove units 3 according to the requirement to mill the required groove structure.

Further, in the embodiment, an elastic sealing sleeve 305 is further sleeved outside the milling cutter 301, and a gap is left between the elastic sealing sleeve 305 and the milling cutter 301. The end of the resilient sealing sleeve 305 remote from the housing 11 may be fixedly connected to the first sliding plate 3041 by a connecting plate 3041 b. One end of the elastic sealing sleeve 305, which is far away from the through hole on the shell 11, is communicated with a negative pressure mechanism 5. During operation, the negative pressure mechanism 5 is used for pumping negative pressure into the elastic sealing sleeve 305, so that the crushed dust generated in the milling process is pumped away, and the dust pumping effect is realized. Meanwhile, the elastic sealing sleeve 305 can be elastically deformed, so that when the moving assembly 304 drives the milling cutter 301 to move towards the direction close to the workpiece, the movement of the milling cutter 301 is not hindered.

As shown in fig. 3, the negative pressure mechanism 5 includes a negative pressure manifold 51, a negative pressure branch pipe 52, and a negative pressure suction device (not shown in the figure). Wherein the negative pressure manifold 51 is communicated with a negative pressure pumping device; one end of the negative pressure branch pipe 52 is communicated with the negative pressure manifold 51 through a pipe joint 53, and the other end of the negative pressure branch pipe 52 is communicated to a corresponding elastic sealing sleeve 305; so that the negative pressure is pumped into the elastic sealing sleeve 305 by the negative pressure pumping device. The negative pressure pumping device is electrically connected with the main control mechanism.

In the embodiment, the milling cutters in the hole milling unit 4 can also be used for processing through holes with different shapes according to requirements; for example, a milling cutter for machining a stepped hole, a round hole, a tapered hole, or the like is exemplified. In this embodiment, the milling cutter in the hole milling unit 4 is a milling cutter for machining a stepped hole.
