Description

Technical Field

[0001] This application relates to the field of mechanical tooling technology, and more specifically, to a milling tooling for a support-type projectile. Background Technology

[0002] External milling refers to the cutting process performed on the outside of a workpiece, typically using a large tool to cut along the workpiece's outer contour or plane. External milling is suitable for machining the outer surfaces and complex contours of workpieces; for example, in machining keys, external milling is used to create the key's shape and grooves.

[0003] In related technologies, clamping fixtures are generally used to fix the workpiece in place so that carbide cutting tools can be used to machine the outer surface of the workpiece. In actual machining processes, it is necessary to perform inclined external milling on the surface of the workpiece, that is, to perform oblique cutting on the surface of the workpiece to meet the requirements of practical use.

[0004] However, traditional clamping fixtures do not have the function of tilting and fixing the workpiece for inclined external milling. Therefore, how to provide an external milling fixture according to actual needs is one of the urgent problems to be solved. Utility Model Content

[0005] In view of this, embodiments of this application provide a milling fixture for an externally milled projectile with a support plate.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A milling fixture for a support-type projectile body includes:

[0008] The base has a first column and a second column at its top, with the height of the first column being greater than that of the second column. The two sides of the first column and the second column are connected by side plates, and a storage groove is formed between the first column and the second column. An arc-shaped hole is provided on the side plate near the storage groove.

[0009] A shelf is rotatably disposed within the storage slot. A positioning rod is provided on the side of the shelf, and the positioning rod passes through the arc-shaped hole. The shelf can move within the arc-shaped hole through the positioning rod.

[0010] A fastening nut is provided at the end of the positioning rod by means of a threaded connection. The fastening nut is used to abut against the outer surface of the side plate to fix the shelf in a preset position.

[0011] A balancing assembly is respectively disposed on the first and second pedestals. The balancing assembly includes a pressure plate, a telescopic arm, and a guide rod. The guide rod is fixedly disposed on the upper surface of the first and second pedestals and is located beside the telescopic arm. The pressure plate is slidably disposed on the upper surface of the first and second pedestals via the telescopic arm. The pressure plate is parallel to the upper surface of both pedestals and is also slidably connected to the guide rod. The guide rod is provided with positioning nuts at both the upper and lower ends of the pressure plate.

[0012] In some possible implementations, the outer surface of the side plate is also provided with an arc-shaped groove that coincides with the arc-shaped hole. The width of the arc-shaped groove is greater than the width of the arc-shaped hole. The fastening nut is located in the arc-shaped groove and contacts the groove wall of the arc-shaped groove. The groove wall of the arc-shaped groove is provided with anti-slip protrusions.

[0013] In some possible implementations, the depth of the arcuate groove is equal to the thickness of the fastening nut.

[0014] In some possible implementations, the pressure plate of the balancing assembly is rotatably provided with ball bearings at the position where it contacts the shelf.

[0015] In some possible implementations, the pressure plate and the first and second columns are provided with waist holes that cooperate with the guide rod, and the waist holes extend along the length of the pressure plate.

[0016] In some possible implementations, the interior of the first column and the second column is a hollow structure, and the sides of the first column and the second column are provided with multiple interconnected through holes, which are equidistantly distributed along the vertical direction.

[0017] Both guide rods of the balancing assembly are provided with the through holes;

[0018] A positioning rod is inserted into the through hole.

[0019] The disc-type external milling fixture for projectiles provided in this application has at least the following beneficial effects:

[0020] In the external milling fixture for support-type projectiles provided in this application embodiment, the workpiece to be tilted and milled is placed on the mounting plate, and the mounting plate is adjusted to a suitable position. The mounting plate is fixed by tightening the fastening nuts at the ends of the positioning rods on the mounting plate, so that the fastening nuts abut against the side plates. Then, the pressure plates of the balancing components on the first and second columns abut against both ends of the workpiece, thereby fixing the workpiece in a balanced position. Using the above structural design, the mounting plate can be rotated to tilt and fix the workpiece to different angles, thereby achieving tilted external milling processing at different angles.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-2As shown in the embodiment of this application, the support-type projectile external milling fixture includes a base 100, a storage plate 500, a fastening nut 600, and a balancing assembly. The base 100 is the supporting structure for the external milling fixture. A first column 200 and a second column 300 are respectively provided on both sides of the top of the base 100. The height of the first column 200 is greater than the height of the second column 300, and both sides of the first column 200 and the second column 300 are connected by side plates 400. The first column 200 and the second column 300 are not directly connected; the first column 200, the second column 300, and the side plate 400 form a storage groove 110. Furthermore, an arc-shaped hole 410 is provided on the side plate 400 near the storage groove 110.

[0028] A shelf 500 is rotatably mounted in the storage groove 110 between the first column 200 and the second column 300. Specifically, the middle part of the shelf 500 is rotatably connected to the side plate 400. A positioning rod 510 is provided on the side wall of the shelf 500 in the thickness direction. The positioning rod 510 passes through the arc-shaped hole 410 and extends to the outside of the storage groove 110. Therefore, the shelf 500 can rotate along the extension direction of the arc-shaped hole 410 via the positioning rod 510.

[0029] In addition, a fastening nut 600 is threaded onto the end of the positioning screw, which secures the placement plate 500 in a preset position by abutting against the outer surface of the side plate 400. In actual use, the workpiece to be processed can be placed on the placement plate 500, and the processing angle of the workpiece can be adjusted by rotating the placement plate 500, thereby achieving inclined external milling.

[0030] In this embodiment, a balancing assembly is also provided on the first column 200 and the second column 300. The balancing assembly includes a pressure plate 700, a telescopic arm 800, and a guide rod 900. The top surfaces of the first column 200 and the second column 300 are connected to the pressure plate 700 via the telescopic arm 800, and the first column 200 and the second column 300 are perpendicular to the telescopic arm 800. The top surfaces of the first column 200 and the second column 300 are also provided with a guide rod 900, which is located beside the telescopic arm 800 and is slidably connected to the pressure plate 700. That is, the pressure plate 700 can move vertically along the guide rod 900.

[0031] The guide rod 900 is equipped with positioning nuts 910 at both the upper and lower ends of the pressure plate 700. These positioning nuts 910 fix the pressure plate 700 at a preset vertical position on the guide rod 900. In actual use, after the placement plate 500 is fixed in the preset position by the fastening nuts 600, the pressure plate 700 on the first column 200 and the second column 300 is moved so that the pressure plate 700 can abut against the surface of the workpiece placed on the placement plate 500. This ensures that the placement plate 500 and the workpiece are in a balanced state, preventing unilateral rotation during inclined external milling. Preferably, ball bearings 710 can be provided at the contact point between the pressure plate 700 and the workpiece on the placement plate 500. These ball bearings 710 facilitate the removal of the workpiece from between the placement plate 500 and the pressure plate 700, thus saving the steps required for disassembling the workpiece.

[0032] In the external milling fixture for support-type projectiles provided in this application embodiment, the workpiece to be tilted and milled is placed on the mounting plate 500, and the mounting plate 500 is adjusted to a suitable position. The mounting plate 500 is fixed by tightening the fastening nut 600 at the end of the positioning rod 510 of the mounting plate 500, so that the fastening nut 600 abuts against the side plate 400. Then, the pressure plate 700 of the balancing assembly on the first column 200 and the second column 300 abuts against both ends of the workpiece, thereby fixing the workpiece in a balanced position. Using the above structural design, the mounting plate 500 can be rotated to tilt and fix the workpiece to different angles, thereby achieving tilted external milling processing at different angles.

[0033] In some embodiments, the outer surface of the side plate 400 is further provided with an arc-shaped groove 420, which is designed to overlap with the arc-shaped hole 410. The width of the arc-shaped groove 420 is greater than the width of the arc-shaped hole 410. Anti-slip protrusions are provided on the bottom wall of the arc-shaped groove 420. The side wall of the fastening nut 600 contacts the bottom wall of the arc-shaped groove 420 through the anti-slip protrusions, thereby increasing the friction between them and improving the stability of the shelf 500 in the preset position.

[0034] Preferably, the thickness of the fastening nut 600 is equal to the depth of the arc-shaped groove 420, which allows the fastening nut 600 to be completely embedded in the arc-shaped groove 420, thereby improving the aesthetics of the tooling. Of course, the width of the arc-shaped groove 420 is greater than the outer diameter of the fastening nut 600, which facilitates the use of tools to operate the fastening nut 600.

[0035] In some embodiments, the pressure plate 700, the first column 200, and the second column 300 are provided with waist holes 720 that cooperate with the guide rod 900. The waist holes 720 extend along the length of the pressure plate 700. The actual position of the guide rod 900 can be moved through the waist holes 720 to prevent the guide rod 900 from blocking the workpiece on the shelf 500 and preventing it from rotating.

[0036] In some embodiments, the first column 200 and the second column 300 have a hollow internal structure, and multiple vertically distributed through holes 120 are provided on the sides of the first column 200 and the second column 300. Simultaneously, a corresponding through hole 120 is also provided on the guide rod 900, and a positioning rod 130 is inserted into the through hole 120. In actual use, after the workpiece on the shelf 500 is fixed by the pressure plate 700, the positioning rod 130 can be inserted into the through hole 120 of the guide rod 900 to improve the balance effect of the pressure plate 700 on the workpiece.
