Description

Technical Field

[0001] This utility model belongs to the field of motor manufacturing technology, specifically relating to a tooling for milling the outer side ribs of a machine casing. Background Technology

[0002] One existing type of casing, such as Figure 7 As shown, it is a cast aluminum housing, which includes a housing body. Six ribs are equidistantly arranged on the outer surface of the housing body. Each rib has a threaded hole 1' on each of its two end faces. A notch 2' is provided in the middle of each rib, and the threaded holes 1' on both sides of the rib communicate with the notch 2'. The production process of this cast aluminum housing is as follows: first, aluminum is cast to form the housing body and the six ribs on the outer surface of the housing body; then, an M12 threaded hole is opened on each of the two end faces of the six ribs; finally, a notch 2' is milled in the middle of each of the six ribs. Currently, when milling the notch in the cast aluminum housing, a base plate 4' is installed on the machine tool worktable of a vertical machining center. The upper end face of the base plate 4' has an arc-shaped groove, and the bottom surface of the arc-shaped groove has a rib clearance groove. Then, the housing 5' to be milled is placed in the arc-shaped groove of the base plate, with the ribs at the bottom of the housing located in the rib clearance groove. The arc-shaped surface at the bottom of the housing makes full contact with the arc-shaped groove. Then, a "7"-shaped clamping block 6' is set on each side of the housing to be milled. The vertical block of the "7"-shaped clamping block 6' extends into the central through hole of the housing, and the lower end of the vertical block presses against the inner wall of the housing. The horizontal block of the "7"-shaped clamping block is fixedly connected to the upper end of the base plate 4' by bolts 7', achieving clamping of the housing 5' to be milled before processing. Then, the vertical machining center is started to mill the notch on the uppermost rib. After milling one, the "7"-shaped clamping block is released and removed. The housing is then manually flipped so that the rib to be milled is directly above. The "7"-shaped clamping block is then used to clamp the housing. The vertical machining center is then started to mill the notch on the uppermost rib, and so on until all six ribs are milled sequentially. Our company's tooling (such as...) Figure 6 As shown in the figure, the machining notch of the housing requires six assembly and disassembly steps, which reduces the machining efficiency of the housing. In addition, the manual labor intensity is relatively high. Utility Model Content

[0003] Design objective: To overcome the shortcomings of the prior art, this design aims to create a milling fixture for the outer ribs of a machine housing that not only improves the processing efficiency of the housing but also reduces the labor intensity of workers, ensures processing quality, and prevents vibration during machining of the housing in a vertical machining center.

[0004] Design scheme: To achieve the above design objectives.

[0005] 1. The vertical plate in the mounting base has a circular through hole that penetrates both sides of the vertical plate. The vertical plate also has a pin through hole that penetrates both sides of the vertical plate, and the center distance between the pin through hole and the circular through hole matches the center distance between the central through hole and the threaded hole in the machine housing to be processed. The rotating disk is composed of a first cylindrical segment, a second cylindrical segment, and a third cylindrical segment, which are integrally structured. The center lines of symmetry of the first cylindrical segment, the second cylindrical segment, and the third cylindrical segment coincide. One of the second cylindrical segments... The device has a first cylindrical section on one side and a third cylindrical section on the other side of the second cylindrical section. The diameter of the second cylindrical section is larger than the diameter of the first cylindrical section. The diameter of the first cylindrical section matches the diameter of the circular through hole. The diameter of the second cylindrical section is larger than the diameter of the third cylindrical section, and the diameter of the third cylindrical section matches the diameter of the stop of the machine housing to be processed. The machine housing to be processed is rotatably mounted between two mounting seats via two rotating discs. The design of inserting a limiting pin after the pin through hole and the corresponding threaded hole are aligned is one of the technical features of this utility model. The purpose of this design is as follows: the vertical plate in the mounting base has a circular through hole that penetrates both sides of the vertical plate; the vertical plate also has a pin through hole that penetrates both sides of the vertical plate, and the center distance between the pin through hole and the circular through hole matches the center distance between the central through hole and the threaded hole in the machine housing to be processed; the rotating disk is composed of a first cylindrical segment, a second cylindrical segment, and a third cylindrical segment in an integral structure, with the symmetrical center lines of the first, second, and third cylindrical segments coinciding; the first cylindrical segment is located on one side of the second cylindrical segment, and the third cylindrical segment is located on the other side of the second cylindrical segment; the diameter of the second cylindrical segment is larger than the diameter of the first cylindrical segment, and the diameter of the first cylindrical segment matches the diameter of the circular through hole. The second cylindrical segment has a larger diameter than the third cylindrical segment, and the diameter of the third cylindrical segment matches the diameter of the stop of the housing to be processed. The housing to be processed is rotatably mounted between two mounting seats via two rotating discs. After the pin through hole and the corresponding threaded hole are aligned, a limiting pin is inserted. After a rib notch is machined on the vertical machining center, only two limiting pins need to be pulled out, and the operator can rotate the housing to be processed. When the next rib to be milled is directly above and the pin through hole and the corresponding threaded hole are aligned, a limiting pin is inserted. Then, the vertical machining center is started to machine the rib notch. This not only greatly improves the processing efficiency of the housing but also reduces the labor intensity of the operator while ensuring the processing quality of the housing.

[0006] 2. The rotating disk has a through hole penetrating both sides of the rotating disk, and the center line of the through hole coincides with the center line of the first cylindrical section. The two rotating disks and the machine housing to be processed are fixedly connected by tension screws and locking nuts after the two third cylindrical sections are engaged with the corresponding machine housing stop. This design is the second technical feature of this utility model. The purpose of this design is that the rotating disk has a through hole penetrating both sides of the rotating disk, and the center line of the through hole coincides with the center line of the first cylindrical section. The two rotating disks and the machine housing to be processed are fixedly connected by tension screws and locking nuts after the two third cylindrical sections are engaged with the corresponding machine housing stop. In addition, two limiting pins are used to limit the rotation direction of the machine housing. In this way, the machine housing is linked and fixedly supported by two mounting seats on both sides, which can prevent the vibration phenomenon when processing the machine housing in a vertical machining center.

[0007] 3. The upper surface of the machine tool worktable is provided with two inverted T-shaped grooves that extend through both sides of the machine tool worktable. Each T-shaped groove contains two "convex"-shaped blocks, and the upper surface of each "convex"-shaped block has a threaded hole. The upper surface of the bottom panel of the mounting base is provided with two bolt through holes that extend through both the upper and lower surfaces of the bottom panel. The design of fixing the mounting base to the machine tool worktable with bolts after the two bolt through holes are aligned with the corresponding threaded holes is the third technical feature of this utility model. The purpose of this design is as follows: the upper surface of the machine tool worktable is provided with two inverted T-shaped grooves that run through both sides of the machine tool worktable. Each T-shaped groove contains two "convex"-shaped blocks, and the upper surface of each "convex"-shaped block has a threaded hole. The upper surface of the bottom panel of the mounting base is provided with two bolt through holes that run through both the upper and lower ends of the bottom panel. The mounting base is fixed to the machine tool worktable by bolts after the two bolt through holes are aligned with the corresponding threaded holes. In this way, the tool is set using one side of the mounting base (such as the left side mounting base) as a reference (as a fixed base), and the other side of the mounting base (such as the right side mounting base) serves as a movable base (to clamp the machine housing to be processed and to remove the machine housing after processing). This allows the requirement of batch processing of the outer rib of the machine housing milling fixture to be completed in one tool setting.

[0008] 4. The design of the bolt through hole as a strip-shaped hole is the fourth technical feature of this utility model. The purpose of this design is that the bolt through hole is a strip-shaped hole, which facilitates the installation of the mounting base.

[0009] 5. The design of having multiple triangular plates between the vertical plate and the bottom plate of the mounting base is the fifth technical feature of this utility model. The purpose of this design is that having multiple triangular plates between the vertical plate and the bottom plate of the mounting base can improve the strength of the mounting base, thereby increasing its service life.

[0010] Technical Solution: A fixture for milling the outer rib of a machine housing includes a machine tool table, two mounting bases, and two rotating disks. The vertical plate of each mounting base has a circular through-hole penetrating both sides of the vertical plate. The vertical plate also has pin through-holes penetrating both sides of the vertical plate, with the center distance between the pin through-hole and the circular through-hole matching the center distance between the central through-hole and the threaded hole in the machine housing to be machined. Each rotating disk is composed of a first cylindrical segment, a second cylindrical segment, and a third cylindrical segment, forming an integral structure. The center lines of the symmetrical center lines of the first and second cylindrical segments are symmetrical. The centerline coincides with the symmetrical centerline of the third cylindrical segment. The second cylindrical segment has a first cylindrical segment on one side and a third cylindrical segment on the other side. The diameter of the second cylindrical segment is larger than the diameter of the first cylindrical segment. The diameter of the first cylindrical segment matches the diameter of the circular through hole. The diameter of the second cylindrical segment is larger than the diameter of the third cylindrical segment, and the diameter of the third cylindrical segment matches the diameter of the stop of the machine housing to be processed. The machine housing to be processed is rotatably mounted between two mounting seats via two rotating discs. After the pin through hole and the corresponding threaded hole are aligned, a limiting pin is inserted.

[0011] Compared with the prior art, this utility model has two advantages: first, the machining tool for the outer rib of the housing can not only improve the machining efficiency of the housing, but also reduce the labor intensity of the workers; second, the machining tool for the outer rib of the housing can not only guarantee the machining quality, but also prevent the problem of vibration.
