Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically to an easily replaceable ultra-precision machine pressure roller. Background Technology

[0002] In the bearing manufacturing process, it is necessary to fix the bearing position in order to prevent the bearing from shifting during the manufacturing process and affecting the machining accuracy. The basic fixing method is to use pressure rollers for limiting.

[0003] A bearing ultra-precision machine pressure roller clamping device, with the existing authorized publication number "CN210757110U", includes a pressure rod assembly, a lifting assembly, an adjusting assembly, and a base. The adjusting assembly is adjustablely mounted on the base. By fixing the pressure rod assembly to the drive end of the lifting assembly, the lifting assembly drives the pressure rod assembly to perform vertical lifting and lowering movements to clamp the bearing. The fixing method of the pressure rod assembly is stable and will not swing, thus achieving a good clamping and positioning effect. Furthermore, by symmetrically arranging two sets of pressure rods, which press on both ends of the outer circumference of the bearing respectively, the force on each point on the bearing surface is uniform, resulting in good machining accuracy. This solves the technical problems of poor clamping and positioning effect, uneven force on the bearing surface, and poor machining accuracy existing in the prior art.

[0004] However, during the bearing processing, the device requires multiple adjustments to the bearing's position, and even after adjustment, it is difficult to keep the bearing in the center position for processing. If the bearing shifts during processing, the bearing's accuracy will be affected. Utility Model Content

[0007] Preferably, the top and bottom of the first mounting tube are symmetrically provided with through grooves, and the outer side of the pressure plate is provided with a limiting plate, the length of which is greater than the length of the through groove, to prevent the pressure plate from coming out of the inside of the first mounting tube.

[0008] Preferably, one side of the second threaded rod is made of an arc-shaped structure, and one side of the bottom of the push plate is a slope, so that the second threaded rod can push the two sets of push plates to separate.

The sliding plates are slidably connected to the inside of the limiting grooves to limit the second mounting tube, so that the second mounting tube will not rotate with the first threaded rod during the rotation of the first threaded rod.

[0010] Preferably, the inner side of the first mounting tube is provided with threads, and the first threaded rod is located at the thread, which facilitates fixing the position of the first threaded rod.

[0011] Preferably, a bearing is provided on one side of the first threaded rod, and the second mounting tube is located inside the bearing to prevent the first threaded rod from driving the second mounting tube to rotate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the easily replaceable ultra-precision machine pressure roller;

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3 The present invention provides an embodiment of an easily replaceable ultra-precision press roller, comprising a mounting plate 1, a first mounting tube 7 on one side of the mounting plate 1, a first threaded rod 8 inside the first mounting tube 7, a thread on the inner side of the first mounting tube 7, the first threaded rod 8 being located at the thread for easy fixing of the position of the first threaded rod 8, a second threaded rod 10 on one side of the first threaded rod 8, a knob 9 on one side of the second threaded rod 10, a second mounting tube 11 on one side of the first threaded rod 8, a bearing on one side of the first threaded rod 8, the second mounting tube 11 being located inside the bearing to prevent the first threaded rod 8 from driving the second mounting tube 11 to rotate, symmetrically provided limiting grooves 2 at both ends inside the first mounting tube 7, and symmetrically provided sliding plates 14 at both ends of the second mounting tube 11, the sliding plates 14 being slidably connected inside the limiting grooves 2 to limit the second mounting tube 11, so that the second mounting tube 11 will not rotate with the first threaded rod 8 during the rotation of the first threaded rod 8;

[0020] The second mounting tube 11 is located inside the first mounting tube 7. The top and bottom of the first mounting tube 7 are symmetrically provided with pressure plates 3 and through grooves. The outer side of the pressure plate 3 is provided with a limiting plate 6, and the length of the limiting plate 6 is greater than the length of the through groove to prevent the pressure plate 3 from coming out of the inside of the first mounting tube 7. The first magnet 12 is provided on one side inside the first mounting tube 7 and is located between the two sets of pressure plates 3. The top of the pressure plate 3 is provided with a hidden groove 4 and the inside of the hidden groove 4 is provided with a sloping baffle 5. The top and bottom of the second mounting tube 11 are symmetrically provided with push plates 13. One side of the second threaded rod 10 is made of an arc structure. One side of the bottom of the push plate 13 is sloping, so that the second threaded rod 10 can push the two sets of push plates 13 to separate. The second magnet 15 is provided on one side inside the second mounting tube 11 and is located between the two sets of push plates 13.

[0021] Working principle: During the bearing fixing process, the bearing is first fitted onto the outside of the first mounting tube 7 and pushed to the position of the mounting plate 1. Then, the first threaded rod 8 is rotated, causing it to enter the interior of the first mounting tube 7. This moves the second mounting tube 11, which pushes the two sets of pressure plates 3 outward, squeezing the inner ring of the bearing and fixing its position. Next, the knob 9 and the second threaded rod 10 are rotated, moving them inward towards the interior of the second mounting tube 11 and squeezing the two sets of push plates 13. This causes the two sets of push plates 13 to move outward towards the exterior of the second mounting tube 11, pushing the inclined baffle 5 outward towards the exterior of the hidden groove 4. This limits the bearing on one side, preventing it from shifting due to force during processing.

[0022] After processing, rotate the first threaded rod 8. When the first threaded rod 8 is unscrewed, it drives the second mounting tube 11 to move out of the inside of the first mounting tube 7, no longer restricting the pressure plate 3. At this time, the first magnet 12 attracts the two sets of pressure plates 3, so that the two sets of pressure plates 3 re-enter the inside of the mounting plate 1. When the second threaded rod 10 is unscrewed out of the outside of the second mounting tube 11, the second magnet 15 attracts the push plate 13, so that the push plate 13 re-enters the inside of the second mounting tube 11, no longer restricting the inclined baffle 5. Then the bearing is taken out.
