Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical parts processing fixtures, and in particular relates to a mechanical parts processing fixture. Background Technology
[0002] In the machining of mechanical parts, especially when performing operations such as drilling, milling or welding, stable clamping of the workpiece is crucial.
[0003] In existing technologies, manual clamps or multiple independent clamps are often used to fix different parts of the workpiece. This method is not only cumbersome and inefficient, but also prone to displacement or vibration of the workpiece during processing due to uneven force or insecure fixing, resulting in decreased processing accuracy, dimensional deviations, or even scrapping of the workpiece. Repeated manual adjustment and clamping also increases the labor intensity of the operator. Therefore, there is an urgent need for a mechanical parts processing fixture that can achieve multi-directional synchronous clamping, automatic reset, and effectively prevent workpiece displacement during processing, so as to improve processing accuracy, stability and efficiency, and reduce material waste. Utility Model Content

At the same time, the linkage clamping plate rotates around the torsion spring rod, so that the clamping block applies clamping force to the workpiece synchronously from multiple directions. This achieves the purpose of effectively preventing the workpiece from shifting or vibrating during the machining process, and significantly improving the machining accuracy and stability.
[0012] 2. This utility model achieves synchronous linkage clamping through multiple sets of clamping blocks under the action of the driving mechanism, which simplifies the operation steps, avoids the tediousness of manually adjusting the clamps one by one, and improves the clamping efficiency.

[0022] In the following description, embodiments of the mechanical parts processing fixture of this utility model will be described with reference to the accompanying drawings.
[0023] Figure 1-4 This invention discloses a machining fixture for mechanical parts, comprising a housing 1. An operating table 3 is fixedly mounted at one end of the housing 1, and a fixed platform 4 is movably mounted at the other end of the operating table 3. A spring 5 is sleeved on the side of the fixed platform 4. A drive motor 10 is fixedly mounted at one end of the operating table 3, and a drive shaft 13 is fixedly mounted at the output end of the drive motor 10. Driven shafts 11 are movably mounted at both ends of the operating table 3. One end of the driven shaft 11 and the drive shaft 13 is threaded. Matching limit rods 6 are movably mounted at the threaded ends of both the drive shaft 13 and the driven shaft 11. Through stable multi-directional synchronous clamping and automatic reset functions, the machining error and scrap rate caused by workpiece displacement are effectively reduced, and material loss is reduced.
[0024] Both the driven shaft 11 and the driving shaft 13 have bevel gears 12 fixedly installed at one end, and the bevel gears 12 are meshed together.
[0025] The operating table 3 has a groove 9 on its side that matches the fixed table 4, and a guide groove 8 on its side that cooperates with the limiting rod 6.
[0026] The limiting rod 6 is set in three sets, and one end of the limiting rod 6 is set with an arc angle that matches the inclined surface of the fixed platform 4.
[0027] The operating table 3 is movably mounted with a clamping plate 7 at three ends, and a torsion spring rod 14 is movably mounted at one end of the clamping plate 7. After processing, the drive motor reverses, the limit rod resets, the fixed table resets under the action of the spring, and the clamping plate automatically springs open and resets under the action of the torsion spring rod, so that the workpiece can be easily removed. This achieves the purpose of simple operation of the mechanical parts processing fixture, quick workpiece loading and unloading, and improved work efficiency. The operating table 3 and the clamping plate 7 are connected by the torsion spring rod 14, and clamping blocks 15 are fixedly mounted at both ends of the clamping plate 7.
[0028] Specifically, multiple clamping blocks achieve synchronous clamping under the action of the drive mechanism, which simplifies the operation steps, avoids the tedious manual adjustment of the clamps one by one, and improves clamping efficiency.
[0029] Working Principle: When using this invention, the user places the workpiece on the fixed platform 4, starts the drive motor 10, and drives the drive shaft 13 to rotate. Through the meshing bevel gears 12, all driven shafts 11 rotate synchronously. The rotational motion of the drive shaft 13 and driven shafts 11 is converted into the linear motion of the end limiting rod 6. The limiting rod 6 moves along the guide groove 8 and abuts against the vertical end face of the fixed platform 4. The movement of the limiting rod 6 pushes the fixed platform 4 to overcome the elastic force of the spring 5 and cause it to move downward. The movement of the fixed platform 4 at the same time acts on the bottom end of the clamping plate 7, overcoming the torsion force of the torsion spring rod 14, forcing the clamping plate 7 to rotate around the torsion spring rod 14. The spring rod 14 rotates, thereby driving the clamping block 15 to move towards the workpiece synchronously from multiple directions and apply a stable clamping force, firmly fixing the workpiece on the fixed table 4, so that the processing operation can be performed. After the processing is completed, the drive motor 10 reverses, driving the drive shaft 13 and the driven shaft 11 to rotate in the opposite direction, driving the limit rod 6 to retract along the guide groove 8. At this time, the fixed table 4 is reset under the action of the spring 5. At the same time, the clamping plate 7 loses the force transmitted by the limit rod 6 through the fixed table 4, and automatically springs open and resets under the torque of the torsion spring rod 14. The clamping block 15 releases the workpiece, and the operator can easily take out the processed workpiece.
[0030] Therefore, by driving the drive motor to rotate the main shaft, and using the bevel gear meshing transmission to drive multiple sets of driven shafts to rotate synchronously, multiple sets of limit rods are driven to move along the guide groove, pushing the fixed table to move and compressing the spring. At the same time, the linkage clamping plate rotates around the torsion spring rod, so that the clamping block applies clamping force to the workpiece synchronously from multiple directions. This achieves the purpose of the mechanical parts processing clamp to effectively prevent the workpiece from shifting or vibrating during the processing, and significantly improve the processing accuracy and stability.
[0031] In summary, this machining fixture for mechanical parts uses a drive motor 10 to drive the active shaft 13 to rotate. The bevel gear 12 meshes and drives multiple driven shafts 11 to rotate synchronously, driving multiple limit rods 6 to move along the guide groove 8. This pushes the fixed table 4 to move and compresses the spring 5. Simultaneously, the clamping plate 7 rotates around the torsion spring rod 14, causing the clamping blocks 15 to apply clamping force to the workpiece synchronously from multiple directions. This effectively prevents the workpiece from shifting or vibrating during machining, significantly improving machining accuracy and stability. Furthermore, the synchronous linkage clamping achieved by multiple clamping blocks 15 under the action of the drive mechanism, and the automatic reset of the fixed table 4 under the action of the spring 5 and the clamping plate 7 under the action of the torsion spring rod 14 after machining, simplify operation steps, improve clamping and unloading efficiency, and reduce machining errors and scrap rates.
[0032] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
