Description

Technical Field

[0001] This utility model relates to the field of milling fixture technology, specifically a special fixture for milling surfaces of multiple parts. Background Technology

[0002] Traditional milling relies on manual clamping and unclamping, meaning operators need skills to ensure parts are properly secured and to closely monitor the machine during machining. This high degree of manual intervention not only increases labor intensity but can also lead to quality variations due to human error.

[0003] Each part requires clamping and disassembly, and this non-processing time accounts for a significant portion of the entire processing cycle, especially in mass production, where the accumulated time cost is substantial. Therefore, improving processing efficiency is crucial.

[0004] To address this issue, existing technology discloses a special milling fixture (publication number CN222114277U), which employs a clamping structure between adjacent parts to separate parts that were originally in contact with each other, maintaining a gap between them. This prevents the milling cutter from affecting other machined or unmachined parts during the machining process. Through the cooperation of the clamping structure, the limiting structure, and the adjusting rod, the parts can be flipped over during machining without being removed and re-clamped, so that the bottom surface of the parts faces upward, thus improving machining efficiency.

[0005] However, the aforementioned fixtures have significant limitations on the shape of the parts during clamping, resulting in poor adaptability. Furthermore, during milling, rotation is not possible, and disassembly and reassembly are still required to mill the other side. Therefore, this application provides an improved multi-part milling fixture. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this utility model discloses a special fixture for milling multiple parts, which solves the problems of limited shape restrictions, poor adaptability, and the inability to rotate the parts during milling, requiring disassembly and reassembly for milling operations on the other side.

[0007] The present invention provides a special fixture for milling multiple parts, including a fixture for holding the target object and a rotating component combined with the fixture;

[0008] The clamp includes a support plate, one or more limiting strips are provided on the top of the support plate, a limiting plate is provided on the limiting strips, and the target object is clamped in the middle of the limiting plate for restricting the target object;

[0009] The rotating component includes a body, and one or more mounting slots are arranged in a circular array on the outer side of the plate, the mounting slots being adapted to the support plate.

[0010] As a further improvement of this utility model, a baffle is provided on the top of the support plate, and the baffle contacts a portion of the outer side of the target object to resist the target object.

[0011] As a further improvement of this utility model, an insertion hole is provided between the two limiting strips of the support plate. The insertion hole corresponds to the center of the target object and is fixed by a positioning shaft.

[0012] As a further improvement of this utility model, the support plate has a locking hole at the middle of both ends, and the bottom of the support plate is adapted to the outer side of the rotating component.

[0013] As a further improvement of this utility model, one or more vertical blocks are provided at both ends of the support plate, and the top of the vertical block is provided with a screw hole adapted to the stop bar. A bolt is installed at the screw hole to fix the stop bar to the vertical block.

[0014] As a further improvement of this utility model, two symmetrically arranged positioning holes are provided on the inner side of the mounting groove. The positioning holes correspond to the snap holes of the support plate and are fixed by positioning pins.

[0015] As a further improvement of this utility model, a collection groove is provided between the two mounting grooves for collecting the debris from the milled surface.

[0016] As a further improvement of this utility model, an inner cavity is provided on the inner side of the body, and slots are provided at both ends of the inner cavity. A combination plate is installed in the slot, and the middle part of the combination plate is adapted to the driving component.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model reduces clamping and disassembly time by clamping multiple parts at once, and achieves multi-face milling by rotating components without the need for repositioning and clamping.

[0019] Furthermore, the combined use of the limiting plate, stop bar, and positioning shaft ensures the stability of the parts during the machining process, reduces vibration and tolerance, and can adapt to parts of different shapes and sizes by adjusting the position of the limiting bar and limiting plate.

[0030] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0031] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0032] Traditional milling relies on manual clamping and unclamping. Each time a part is machined, clamping and unclamping are required. This non-machining time accounts for a considerable part of the entire machining cycle, especially in mass production, where the accumulated time cost is significant.

[0033] To address this problem, this application provides a dedicated fixture for milling multiple parts. Please refer to [link / reference]. Figure 1-6 It includes a clamp 2 for holding the target object 26 and a rotating component 1 combined with the clamp 2;

[0034] The clamp 2 includes a support plate 22, one or more limiting strips 21 are provided on the top of the support plate 22, and a limiting plate 28 is provided on the limiting strip 21. The target object 26 is clamped in the middle of the limiting plate 28 for restricting the target object 26.

[0035] The rotating component 1 includes a body 11, and one or more mounting slots 12 are arranged in a ring array on the outer side of the plate. The mounting slots 12 are adapted to the support plate 22.

[0036] The rotating component 1 is used in conjunction with the clamp 2 to clamp multiple target objects 26 during milling operations.

[0037] During the assembly of fixture 2, the limiting plate 28 in fixture 2 can restrict the target object 26. By restricting it, it is ensured that at least one side of the target object 26 is on the running trajectory of the milling cutter, so that it can be processed.

[0038] For details, please refer to [link / reference]. Figure 1 In this case, a circular target object 26 is used. The method of restriction is to make the outer circular contour of the target object 26 face outward, and it is processed with a milling cutter.

[0039] The combination of the limiting plate 28 can be adjusted under the restriction of the limiting strip 21 to meet the needs of target objects 26 of different sizes;

[0040] When the rotating component 1 is used, its mounting groove 12 can fit with the bottom of the support plate 22, thereby limiting its position.

[0041] By cooperating with the rotating component 1 and the clamp 2, multiple target objects 26 can be processed at one time, improving milling efficiency. Moreover, the fixed method can restrict the target object 26 during milling, avoiding the problem of milling surface movement. Furthermore, when adjustments are needed later, its modular assembly method allows for quick adjustments to meet different needs.

[0042] A baffle 24 is mounted on the top of the support plate 22. The baffle 24 contacts a portion of the outer side of the target object 26 and is used to abut against the target object 26.

[0043] The support plate 22 has a insertion hole between the two limiting strips 21, which corresponds to the center of the target object 26 and is fixed by the positioning shaft 25.

[0044] To ensure the stability of the milled surface, a stop bar 24 can be added when restricting the target object 26. The stop bar 24 abuts against the top of the target object 26, thereby improving the stability of the target object 26 when it is restricted.

[0045] In some embodiments, the baffle 24 may be two; see [link / reference] Figure 1 , Figure 4 and Figure 6 The use of the two stop bars 24, together with the positioning shaft 25 inserted in the middle, can further fix the target object 26, avoid shaking during milling, and improve stability.

[0046] For example, when using a cylinder without a hole in the middle, and when it is necessary to mill the top of the cylinder, the stop bar 24 can clamp the cylinder. In order to increase the friction, a rubber pad can be added to the side that contacts the target object 26 to fix the target object 26.

[0047] That is, the combination of the baffle 24 and the support plate 22 forms a limiting area, which, together with the limiting plate 28, further ensures the fixation of the target object 26.

[0048] The support plate 22 has a locking hole 27 at the middle of both ends, and the bottom of the support plate 22 is adapted to the outer side of the rotating component 1.

[0049] See Figures 1-3 The slot 27 of the support plate 22 is combined with the positioning hole 13 of the mounting groove 12 on the body 11, and the positioning pin is used for insertion and fixation, thereby ensuring the stability of the combination when the rotating part 1 and the clamp 2 are combined.

[0050] One or more vertical blocks 23 are provided at both ends of the support plate 22. The top of the vertical block 23 is provided with a screw hole that matches the stop bar 24. A bolt 29 is installed at the screw hole to fix the stop bar 24 to the vertical block 23.

[0051] The bolt 29, through its combination with the screw hole of the stop bar 24 and the vertical block 23, achieves the fixation of the stop bar 24;

[0052] Furthermore, when in use, the vertical block 23 can be drilled at any point on the outside to connect to different target objects 26 according to their fixing needs, thus meeting different connection requirements.

[0053] For example, when the target object 26 is a cylindrical part, the fixture 2 is configured to use two stops 24 and a positioning shaft 25 to fix the cylindrical part, ensuring that it does not move during the milling process.

[0054] By rotating component 1, milling operations can be performed on multiple sides of the cylindrical part without disassembly and reclamping.

[0055] For example, when the target object 26 is a square part, the fixture 2 is configured to adjust the position of the limiting plate 28 to adapt to the size of the square part, and uses the stop bar 24 to abut and fix the top of the part. The rotating component 1 rotates at a certain angle so that different faces of the square part are aligned with the milling cutter in sequence, realizing multi-face milling.

[0056] It should also be noted that two symmetrically arranged positioning holes 13 are provided on the inner side of the mounting groove 12. The positioning holes 13 correspond to the locking holes 27 of the support plate 22 and are fixed by positioning pins.

[0057] There can be multiple positioning holes 13 provided on the mounting groove 12, and they can be arranged at even intervals. In order to further increase the fit, the positioning holes 13 can be changed into positioning grooves. If the length of the support plate 22 is less than the length of the positioning groove, the two ends of the support plate 22 can be restricted by the cooperation of the locking block and the positioning groove.

[0058] In addition, the present invention also provides a collection groove 15 between the two mounting grooves 12 for collecting the debris from the milled surface.

[0059] During milling, a large amount of chips are generated on the surface of the target object 26. Generally, when milling relatively hard materials, such as hardened steel, cast iron, or high-temperature alloys, coolant may be needed to reduce the cutting temperature and extend tool life. For softer materials, such as aluminum alloys or brass, coolant may not be necessary because they have good thermal conductivity and can effectively dissipate cutting heat. In addition, coolant can help remove chips and prevent them from re-adhering to the workpiece or tool, thereby improving surface quality.

[0060] When coolant is used, debris will flow along with the coolant onto the surface of the target object 26. The collection tank 15 provides guidance for the flow of debris to a certain extent, and also helps the flow of coolant when it is used.

[0061] The inner side of the body 11 is provided with an inner cavity 14, and slots 16 are provided at both ends of the inner cavity 14. A combination plate is installed in the slots 16, and the middle part of the combination plate is adapted to the driving component.

[0062] To facilitate rotation, one end of the driving component (such as a stepper motor) is rotated to one side of the rotating component 1. At this time, the slots 16 set at both ends of the inner cavity 14, through the slots 16 and the set plate, and with the support of the bearing, can drive the rotating component 1 to rotate.

[0063] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
