Description

Technical Field

[0001] The utility model relates to the technical field of milling processing, in particular to a milling device for end face closed special-shaped grooves. Background Art

[0002] Milling is a cutting process that uses a rotating multi-tooth tool (milling cutter) to remove excess material from a workpiece. This process is widely used in the processing of various materials such as metals, plastics, wood, etc. to create planes, grooves, shaped surfaces, gears, and complex three-dimensional geometric shapes.

[0003] For Figure 5 and Figure 6 A casting 20 shown needs to be processed to form a closed end face shaped groove 21, wherein the closed end face shaped groove 21 means that one of the two side surfaces forming the end face groove is a straight surface 21a and the other is an inclined surface 21b, that is, the angle D between the inner walls of the groove of the end face groove is less than a right angle. Since the workpiece is fixedly installed in the existing milling machine, the casting 20 has two fixing methods. For the convenience of description, the end face where the closed end face shaped groove on the casting 20 is located is defined as the surface to be processed 22. In this way, when the casting 20 is fixed on the milling machine, the surface to be processed 22 is either fixed upward or fixed sideways.

[0004] However, no matter how the casting 20 is fixed, the required end face closed special-shaped groove 21 cannot be machined using the existing milling machine. Specifically, when the surface 22 to be machined of the casting 20 is fixed in a vertical direction, since the surface 21b is located in the axial position of the milling cutter, it means that the position where the surface 21b is located can only be machined into a planar structure, and cannot be machined into an inclined structure; when the surface 22 to be machined of the casting 20 is fixed in a sideways direction, the milling cutter can only form a partial structure at most, and the corner position cannot continue to be machined. In view of this, in order to solve the above technical problems, the end face closed special-shaped groove milling device of the present application is proposed. Utility Model Content

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show preferred embodiments of the present invention.

[0031] like Figure 1 and Figure 2 As shown, a milling device 10 for end-face closed special-shaped grooves includes a milling machine 100, a rotating seat 200 and a clamping assembly 300. The rotating seat 200 is arranged on the milling machine 100. The clamping assembly 300 includes a support shaft 310, a solid material block 320, a clamping block 330, a fastener 340 and a plurality of positioning columns 350. The support shaft 310 is detachably arranged on the rotating seat 200 along the transverse direction. The solid material block 320 is arranged on one end of the support shaft 310 away from the rotating seat 200. The positioning columns 350 are arranged at intervals on a side surface of the solid material block 320 away from the support shaft 310. The positioning columns 350 are used to position the casting 20. The fastener 340 is passed through the clamping block 330 and is screwed on the solid material block 320, so that the clamping block 330 and the solid material block 320 clamp the casting 20 together, so that the surface 22 to be processed of the casting 20 is distributed laterally.

[0032] It should be noted that, for example, the rotating seat 200 is a three-claw power head, which is driven by a motor so that the three claws can rotate continuously. It should be noted that the three-claw power head is a prior art and can be purchased on online shopping platforms, so it will not be described in detail here. Furthermore, the solid material block 320 is installed on one end of the support shaft 310 by bolts, or the solid material block 320 and the support shaft 310 are an integrally formed structure. Each positioning column 350 is respectively installed at the four corners of the solid material block 320, and each positioning column 350 is used to pass through the through hole of the casting 20 for positioning, so as to ensure that the end face closed special-shaped groove 21 that needs to be processed on the surface 22 to be processed of the casting 20 is coaxially distributed with the support shaft 310. In this way, positioning is performed by the positioning column 350, which facilitates the loading of the casting 20. Furthermore, the clamping block 330 is used to be placed in the casting 20, and then when the clamping block 330 is fixed to the solid material block 320 by the fastener 340, the clamping block 330 clamps and fixes the casting 20 on the solid material block 320. For example, the fastener 340 is a bolt. In this way, under the action of the clamping assembly 300, the surface 22 to be processed of the casting 20 is horizontally distributed, and then the casting 20 is driven to rotate by the rotating seat 200, and then under the cooperation of the milling machine 100, the milling cutter can process and form a corner part, so that the end face closed special-shaped groove 21 can be smoothly processed on the surface 22 to be processed of the casting 20.

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment, the end face closed special-shaped groove milling device 10 also includes a milling part 400, the milling part 400 includes a shaft column 410 and a locking cover 420, one end of the shaft column 410 is used to fix the milling cutter, the locking cover 420 is rotatably set on the outer wall of the shaft column 410, and the locking cover 420 is used to be screwed to the milling machine 100 to fix the shaft column 410 on the milling machine 100.

[0034] It should be noted that the milling part 400 is used to be installed on the milling machine 100 at a position where the milling cutter is fixed. Specifically, the shaft column 410 is used to fix the milling cutter. For example, a mounting groove is provided on the lower end surface of the shaft column 410, and the milling cutter is fixed to the lower end position of the shaft column 410 through a chuck and a screw cap. It should be noted that the structure of the shaft column 410 fixing the milling cutter is a prior art and will not be described in detail here. The shaft column 410 is different from the prior art in that the locking cover 420 is rotatably mounted on the outer side wall of the shaft column 410, that is, the locking cover 420 can rotate relative to the shaft column 410, but will not withdraw from the shaft column 410. In this way, by rotating the locking cover 420 to be screwed with the part on the milling machine 100 for installing the milling cutter, the shaft column 410 can be fixed on the milling machine, that is, the installation of the milling cutter is completed.

[0035] like Figure 3 , Figure 4As shown, in one embodiment, two bosses 430 are provided on the outer wall of the shaft column 410, a gap is provided between the two bosses 430, and the lock cover 420 is rotatably provided between the two bosses 430. Thus, the outer diameter of the boss 430 is larger than the inner diameter of the lock cover 420, so that the lock cover 420 can rotate relative to the shaft column 410.

[0036] like Figure 1 and Figure 4 As shown, in one embodiment, the end face closed special-shaped groove milling device 10 further includes a replacement part 500 , which is disposed on the milling machine 100 , and is used to carry a plurality of milling parts 400 .

[0037] It should be noted that, in order to form the end face closed special-shaped groove 21 on the to-be-processed surface 22 of the casting 20, a circular milling cutter and a forming milling cutter with a bevel are required, that is, at least two tool change operations are required, and the milling machine in the prior art lacks an automatic tool change function, and workers are required to manually change the milling cutter, which will restrict the processing efficiency of the casting 20. In order to solve this problem, a replacement part 500 is installed on the frame of the milling machine 100, and the replacement part 500 is used to carry at least two milling parts 400 and to install the milling parts 400 on the milling machine 100.

[0038] like Figure 1 and Figure 4 As shown, in one embodiment, the replacement part 500 includes a base 510, a replacement drive unit 520 and a plurality of loading barrels 530. The base 510 is disposed on the milling machine 100. A plurality of loading holes 511 are provided on the base 510. The replacement drive unit 520 is disposed on the base 510. Each loading barrel 530 is respectively inserted into each loading hole 511. The milling machine 100 is used to drive the milling part 400 to push or move away from the loading barrel 530 so as to connect or separate the loading barrel 530 from the replacement drive unit 520.

[0039] It should be noted that the base 510 is fixedly mounted on the frame of the milling machine 100. At least two material placement holes 511 are provided on the base 510, and then each material loading barrel 530 is inserted and installed in each material placement hole 511. The material loading barrel 530 can slide and rotate in the material placement hole 511. In a natural state, when the milling part 400 is placed on the material loading barrel 530, the locking cover 420 and the replacement drive part 520 of the milling part 400 are separated from each other. When the milling part 400 is pushed down by the milling machine 100, the locking cover 420 of the milling part 400 is connected to the replacement drive part 520, so that the replacement drive part 520 can drive the locking cover 420 to rotate relative to the milling machine 100, so that the locking cover 420 is locked or loosened. In this way, the milling part 400 can automatically change the tool.

[0040] like Figure 1 and Figure 4 As shown, in one embodiment, the replacement drive unit 520 includes a replacement motor 521, a power shaft 522, a plurality of ferrules 523 and a plurality of gears 524. The power shaft 522 is rotatably disposed in the base 510, the replacement motor 521 is disposed on the outer wall of the base 510, and the output shaft of the replacement motor 521 is connected to the power shaft 522. Each ferrule 523 is rotatably disposed on the inner wall of each material placement hole 511, and each gear 524 is respectively disposed on the outer wall of each ferrule 523, and each gear 524 is meshed with the power shaft 522.

[0041] It should be noted that the power shaft 522 is installed in the base 510 through a bearing, and the power shaft 522 is driven to rotate by the replacement motor 521. Each ferrule 523 is installed in each material placement hole 511 through a bearing, and each gear 524 is coaxially fixedly installed on the outer wall of each ferrule 523, and the gear 524 is meshed with the power shaft 522. In one embodiment, the combined structure of the power shaft 522 and the gear 524 is a worm gear structure. In this way, the power shaft 522 can simultaneously drive each ferrule 523 to rotate. In one embodiment, the replacement motor 521 and the power shaft 522 are connected by a reducer, so as to ensure that the power shaft 522 has sufficient torque.

[0042] like Figure 4 As shown, in one embodiment, a clamping platform 525 is provided on the inner wall of the clamping sleeve 523, and a clamping slot 421 is opened on the outer wall of the locking cover 420. When the milling machine 100 drives the milling part 400 to push the loading barrel 530, the clamping platform 525 is adaptively inserted into the clamping slot 421.

[0043] It should be noted that when the boss 430 located below the milling part 400 pushes the top of the loading barrel 530, the locking cover 420 descends, so that the clamping platform 525 slides into the clamping groove 421. In this way, the replacement drive unit 520 can drive the locking cover 420 to rotate forward to lock or reverse to release.

[0044] like Figure 4 As shown, in one embodiment, a linear bearing 540 is sleeved on the outer wall of the material loading barrel 530, and the outer wall of the linear bearing 540 is in contact with the inner wall of the material placement hole 511. In this way, it can be ensured that the material loading barrel 530 can slide and rotate stably relative to the material placement hole 511.

[0045] like Figure 4 As shown, in one embodiment, the outer wall of the material carrying barrel 530 is further sleeved with a spring 550 , and the spring 550 is respectively in contact with the material carrying barrel 530 and the linear bearing 540 .

[0046] In this way, when the milling machine 100 drives the milling part 400 downward, the spring 550 is compressed. When the milling machine 100 rises, the loading barrel 530 drives the milling part 400 placed in the loading barrel 530 to rise, thereby disengaging the locking cover 420 from the sleeve 523.

[0047] like Figure 4 As shown, in one embodiment, a clamping ring 512 is provided on the inner wall of the material placement hole 511, and a convex ring 560 is provided on the outer wall of the material loading barrel 530, and the convex ring 560 is respectively in contact with the clamping ring 512 and the spring 550. In this way, the clamping ring 512 clamps and limits the convex ring 560, so that the material loading barrel 530 has the highest limit position.

[0048] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
