Description

Technical Field

[0001] The utility model relates to a flat shaft, in particular to a flat shaft processing jig. Background Art

[0002] Microshafts are relatively small, high-precision shaft components. They can also be called precision shafts, small shafts, shaft cores, rotor shafts, pins, rivets, guide rods, etc. Based on the load-bearing requirements, microshafts can be categorized as follows: First, rotating shafts, which bear both bending and torque during operation, are the most common shafts in machinery, such as those found in various speed reducers. Second, spindles, used to support rotating parts, only bear bending moments but do not transmit torque. Some spindles rotate, such as those in railway vehicles, while others do not, such as those supporting pulleys. Third, drive shafts, primarily used to transmit torque but not bending moments, include long optical shafts in crane travel mechanisms and drive shafts in automobiles. Shafts are primarily made of carbon steel or alloy steel, but ductile iron or alloy cast iron are also acceptable. A shaft's operating capacity generally depends on its strength and rigidity, and at high speeds, also on vibration stability. Flat shafts are a type of microshaft. The existing flattening shaft processing jig cannot position multiple flattening shafts during flattening processing, and cannot realize batch flattening processing of flattening shafts, which greatly affects the processing efficiency of the flattening shafts. Summary of the Invention

[0003] The purpose of the utility model is to overcome the defects of the prior art and provide a flat shaft processing jig with simple structure, stable and reliable performance, convenient assembly and high production efficiency.

[0004] To achieve the above-mentioned purpose, the utility model adopts a flat shaft processing jig, including a bottom plate, a base arranged on the bottom plate, two side plates respectively arranged on the bottom plate at both sides of the corresponding base, two fixed plates respectively arranged on the base, three support plates respectively arranged on the base at both ends of the corresponding fixed plate, and a pressure plate arranged on the three support plates and matched with the two fixed plates. Positioning steps for placing the flat shaft are respectively provided on both sides of the fixed plate, and a clamping cavity for clamping the flat shaft is formed between the positioning step and the pressure plate. One end of the flat shaft is inserted into the clamping cavity, and the other end of the flat shaft extends on the side plate.

[0005] The beneficial effect of the above structure is that the flattened shaft processing jig can achieve the positioning of multiple flattened shafts, thereby facilitating batch flattening of flattened shafts and significantly improving the processing efficiency of flattened shafts. During operation, multiple flattened shafts are placed on the positioning steps of the fixed plate, the pressure plate is pressed against the multiple flattened shafts, and the entire flattened shaft processing jig is installed on the flattening machine to achieve flattening of multiple flattened shafts. This flattened shaft processing jig has the advantages of simple structure, stable and reliable performance, convenient assembly, and high production efficiency.

[0006] In particular, the base is provided with a fixing block, which is symmetrically provided with two positioning protrusions that cooperate with the fixing plate. The fixing plate is provided with two positioning holes that cooperate with the two positioning protrusions. The two positioning protrusions are inserted into the two positioning holes and form a snap-fitting fit between the fixing block and the fixing plate. The base is snap-fitted to the fixing plate via the fixing block, thereby facilitating assembly of the base and the fixing plate, making assembly more convenient.

[0007] In particular, the base is provided with a positioning groove that cooperates with the fixing block. The fixing block is engaged in the positioning groove, forming a snap-fitting engagement between the base and the fixing block. The fixing block is provided with a fastener connected to the base. The engagement of the fixing block in the positioning groove of the base facilitates assembly of the fixing block and the base, thereby improving assembly efficiency.

[0008] Specifically, two positioning blocks are provided at each end of the pressure plate, and positioning slots are provided on the two support plates to match the positioning blocks. The positioning blocks engage within the positioning slots, and the positioning blocks are provided with bolts connected to the support plates. The positioning blocks of the pressure plate engage within the positioning slots of the support plates, thereby facilitating assembly of the pressure plate and the support plates and ensuring a more compact connection between the pressure plate and the support plates.

[0009] In particular, the pressure plate is symmetrically provided with two limiting grooves in the middle portion, and the other support plate is provided with two limiting protrusions that cooperate with the two limiting grooves. The two limiting protrusions engage in the two limiting grooves, thereby forming a limiting cooperation between the two limiting protrusions and the pressure plate. The limiting grooves of the pressure plate engage with the limiting protrusions of the other support plate, thereby facilitating the assembly of the pressure plate and the support plate and ensuring a more compact connection between the pressure plate and the support plate.
