Description

Technical Field

[0001] This utility model relates to the field of casting cutting technology, and in particular to a jig for casting cutting. Background Technology

[0002] Fixtures for casting cutting are key process equipment in the metal processing industry, playing a crucial role in the precision cutting of complex and irregularly shaped castings such as automotive gearbox housings, engineering machinery structural components, and pump bodies and valve cores. With the widespread adoption of high-precision CNC cutting equipment and the increasing demand for thin-walled casting processing, higher requirements are being placed on the vibration suppression capabilities, rapid changeover adaptability, and cutting protection performance of fixture systems. Currently, the industry commonly uses magnetic chucks with locating pins for fixing, or combined fixtures using pneumatic grippers with adjustable-angle bases. These solutions have formed a mature technological system for the batch processing of standard geometric castings.

[0003] However, existing technologies suffer from limitations such as fixed and simplistic strategies, relying on rigid nested structures for workpiece positioning. They cannot adapt to the curved surface features of various types of irregularly shaped castings through the coordinated matching of modular nesting seats and replaceable nesting plugs. This leads to clamping deformation or positioning datum misalignment in thin-walled parts, a lack of safety protection mechanisms, and the traditional open fixture structure allowing cutting debris and coolant to directly impact the equipment's transmission components, accelerating guide rail wear and increasing equipment failure rates. Pressure control accuracy is insufficient; manual knob adjustment of the cutting feed results in uneven pressure application, and the lack of a mechanical amplification design for the grip lever and adjuster easily leads to fluctuations in cutting depth, affecting machining quality. Dynamic stability is weak, and the absence of a synergistic vibration damping structure between the protective cover and mounting base makes it difficult to suppress tool chatter caused by fixture system resonance under high-speed cutting conditions. Therefore, we provide a fixture for casting cutting. Utility Model Content

[0011] In a preferred embodiment, one end of the fixing frame is cast onto the base plate, and one side of the connecting plate is cast onto one side of the fixing frame.

[0028] Example 1

[0029] like Figure 1-4 As shown, this utility model provides a technical solution: a jig for cutting castings, including: a fixing mechanism 1, the fixing mechanism 1 including a base plate 11, a support pad 12 provided at the bottom of the base plate 11, and a clamping mechanism 2 provided on the base plate 11;

[0030] The clamping mechanism 2 includes a fixing screw 21, a mounting base 22 is provided on the outer surface of the fixing screw 21, a nesting base 23 is provided on the mounting base 22, a nesting plug 24 is provided in the nesting base 23, a protective cover 25 is provided on the outer surface of the mounting base 22, and a cutting mechanism 3 is provided on one side of the mounting base 22.

[0031] The cutting mechanism 3 includes a fixed frame 31, a connecting plate 32 is provided on one side of the fixed frame 31, an adjuster 33 is provided on the connecting plate 32, a grip handle 34 is provided at one end of the adjuster 33, and a cutting blade 35 is provided at the end of the adjuster 33 away from the grip handle 34.

[0032] One end of the support pad 12 is cast onto the base plate 11, and one end of the fixing screw 21 is cast onto the base plate 11;

[0033] Mounting base 22 is nested on the outer surface of fixing screw 21, and the outer surface of nesting base 23 is nested on mounting base 22;

[0034] The outer surface of the nested plug 24 is nested in the nested seat 23, and the inner surface of the protective cover 25 is nested in the outer surface of the mounting seat 22;

[0035] One end of the fixing frame 31 is cast onto the base plate 11, and one side of the connecting plate 32 is cast onto one side of the fixing frame 31;

[0036] One side of the regulator 33 is cast onto the side of the connecting plate 32 away from the fixed frame 31, one end of the grip lever 34 is connected to the regulator 33, and one end of the cutting blade 35 is connected to the end of the regulator 33 away from the grip lever 34.

[0037] In this embodiment, when the operator uses this fixture to cut the casting, the mounting base 22 can be installed on the outer surface of the fixing screw 21 to fix it to the base plate 11. Then, the operator can install the casting in the nesting seat 23 and reinforce it with the nesting plug 24. Then, the protective cover 25 is put on the outer surface of the mounting base 22. After that, the operator can press the handle 34 to make the adjuster 33 apply pressure to the cutting blade 35, so that the cutting blade 35 cuts the casting in the nesting seat 23. This improves its practicality in actual use.

[0038] Working principle:

[0039] like Figure 1-4 As shown, when using this fixture to cut castings, the operator first needs to fix the mounting base 22 on the base plate 11. Specifically, the mounting base 22 is firmly installed on the outer surface of the fixing screw 21, and its connection is ensured to provide a stable operating base.

[0040] Next, the worker can place the casting inside the nesting seat 23 and further reinforce it with the nesting plug 24 to prevent it from moving or shaking during the cutting process. To enhance safety, the worker can also cover the outer surface of the mounting seat 22 with a protective cover 25 to prevent debris from flying during the cutting process and ensure the safety of the operator.

[0041] After preparation, the operator can press down on the lever 34, which applies downward pressure to the regulator 33, thereby pushing the cutting blade 35 to cut the casting in the nested seat 23. In this way, the cutting blade 35 can act stably and precisely on the casting, achieving efficient cutting.

[0042] The fixture design not only provides a secure fixation method but also enhances operational flexibility and safety. Operators can adjust the tightness of the nesting plug 24 to accommodate castings of different sizes, according to actual needs. Meanwhile, the use of the protective sleeve 25 further improves safety and reduces potential risks during the cutting process.

[0043] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.
