Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a synchronous grinding machine for internal and external cylindrical surfaces. Background Technology

[0002] In modern machining, the precision and surface quality of components play a decisive role in product performance and reliability. Many key components, such as turbine shafts for aero-engines, crankshafts for automotive engines, and high-precision bearings, have extremely high requirements for the dimensional accuracy, shape accuracy, and surface roughness of their inner and outer diameters. With continuous technological advancements, products are developing towards high performance, miniaturization, and integration, leading to increasingly stringent requirements for component machining precision. For example, in the aerospace field, to improve engine efficiency and reliability, the machining precision of the inner and outer diameters of turbine shafts needs to be controlled at the micrometer level, with extremely low surface roughness. This necessitates advanced grinding equipment to meet the demands of high-precision machining.

[0003] In traditional equipment, the distance between the two grinding discs is mostly fixed. When processing workpieces of different sizes, different equipment needs to be changed, which is not flexible and makes it difficult to ensure that the equipment can meet the required processing requirements. Therefore, a synchronous grinding machine for internal and external cylindrical surfaces is proposed. Utility Model Content

[0014] (III) Beneficial Effects

[0015] This utility model provides a synchronous internal and external cylindrical grinding machine, which has the following beneficial effects:

[0016] 1. This internal and external cylindrical synchronous grinding machine, through the setting of the lifting component, when in use, starts the servo motor, the rotation of the servo motor drives the threaded rod to rotate, the rotation of the threaded rod causes the sliding plate to move on the threaded rod, thereby adjusting the distance between the two sets of grinding discs, so as to adapt to workpieces with different outer and inner diameters, improving the versatility and flexibility of the equipment. At the same time, it can also precisely control the grinding dimensions of the workpiece, so that the grinding disc spacing can be adjusted according to the required processing accuracy and dimensional requirements to ensure that the outer and inner diameters of the workpieces reach the specified tolerance range.

[0017] 2. This internal and external cylindrical synchronous grinding machine, through the setting of the clamping assembly, allows the grinding disc to be removed from the device after a period of use by rotating the rotating block. As the rotating block rotates, it drives the clamping rod to move. When the clamping rod moves, it is pulled out from inside the fixed rod, thus facilitating the replacement of the grinding disc. This avoids the phenomenon that the grinding disc wears down and its grinding capacity and accuracy gradually decrease. The device ensures that the grinding process is always carried out under optimal parameters, such as maintaining stable grinding force, appropriate grinding speed and feed rate, thereby improving machining accuracy and surface quality.

This allows the device to replace the grinding disc 9. The lifting assembly 3 includes a threaded rod 301 set inside the fixed block 2. One end of the threaded rod 301 is fixedly connected to a servo motor 302, and the outside of the servo motor 302 is fixedly connected to a motor housing 303.

[0025] Both sets of fixed cylinders 701 have fixed rods 8 connected inside, and one end of each fixed rod 8 is fixedly connected to a grinding disc 9. The grinding disc 9 is used to grind the workpiece.

[0026] Both sets of fixing cylinders 701 are fixedly connected to magnets 10 inside. One side of each set of magnets 10 is magnetically connected to an electromagnet 11. One end of each set of electromagnets 11 is electrically connected to a controller 12 via a power line. The electromagnets 11 serve to provide additional fixation.
