Abstract
Description
Technical Field
[0001] This utility model relates to the field of oilstone clamping technology, specifically a convenient bearing ultra-precision machine oilstone clamp. Background Technology
[0002] Ultra-precision machines are devices that use fine abrasives such as oilstones to perform micro-cutting on metal surfaces. They press the oilstones against the rotating workpiece with low pressure to form a surface contact state. At the same time, the oilstones vibrate axially at a high frequency. The oilstone clamp is the component that uses oilstones to fix the ultra-precision machine.
[0003] Our company's existing patent with authorization announcement number "CN201720763U" discloses a new type of oilstone clamp for ultra-precision machining of tapered roller bearing outer rings. It mainly includes a clamp body, a clamp head fixedly connected to the clamp body, a fastening screw threadedly connected to the clamp head, and a pressure pad fixedly connected to the end of the fastening screw. The pressure pad is installed in a long groove of the clamp head and slides within it. A nut is fixedly connected to the clamp head, and the fastening screw is threadedly connected to the nut. The beneficial effects of this invention are: by clamping from the side surface under the action of the side pressure pad and the fastening screw, the stability of the oilstone is ensured, making the oilstone less prone to breakage under high-frequency vibration, reducing waste and ensuring processing quality.
[0004] However, the existing fixtures mentioned above still have the following shortcomings in actual use:
[0005] 1. The existing device can only fix the oilstone from the side when fixing it, which results in poor stability. During ultra-precision machining, the oilstone is prone to shaking, which can lead to breakage and reduce the utilization rate of the oilstone.
[0006] 2. When using an oilstone, to prevent it from breaking, the processing section can only extend a small part. As the oilstone wears down and becomes shorter, it needs to be adjusted. The above-mentioned device cannot remind the staff when the processing section of the oilstone is almost worn out, which means that the staff needs to observe the oilstone regularly, making it inconvenient to use. Utility Model Content
[0007] The purpose of this utility model is to provide a convenient bearing ultra-precision machine oilstone clamp to solve the existing problems mentioned in the background art.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a convenient bearing ultra-precision machine oilstone clamp, comprising a clamp body, an mounting block provided on one side of one end of the clamp body, a material feeding groove provided on the inner side of the clamp body, a nut provided on one side of the clamp body, a screw threadedly connected to the inner side of the nut, a clamping plate sleeved on one side of the screw extending into the material feeding groove, a sliding groove provided on the top of one side of the clamping plate, a slider slidably connected to the inner side of the sliding groove, a pressure plate provided on one side of the slider, a movable rod sleeved on the top of the sliding groove, a spring B connected to the movable rod provided on the top of the slider, a guide wheel provided on the top of the movable rod, a trapezoidal groove cooperating with the guide wheel provided on one side of the top of the inner side of the material feeding groove, and a prompting component provided on one side of one end of the clamp body.

Detailed Implementation
[0022] 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.
[0023] Please see Figure 1-4The present invention provides an embodiment of a convenient bearing ultra-precision machine oilstone clamp, comprising a clamp body 1, an mounting block 14 on one side of one end of the clamp body 1, a material feeding groove 2 on the inner side of the clamp body 1, a nut 5 on one side of the clamp body 1, a screw 4 threadedly connected to the inner side of the nut 5, a knob on the side of the screw 4 away from the clamping plate 6 for easy rotation of the screw 4, one side of the screw 4 extending into the material feeding groove 2 and fitted with the clamping plate 6, a sliding groove 16 on the top of one side of the clamping plate 6, a slider 18 slidably connected to the inner side of the sliding groove 16, a pressure plate 3 on one side of the slider 18, a movable rod 21 fitted on the top of the sliding groove 16, a spring B17 connected to the movable rod 21 on the top of the slider 18, a guide wheel 15 on the top of the movable rod 21, a trapezoidal groove 20 cooperating with the guide wheel 15 on one side of the top of the inner side of the material feeding groove 2, and a prompting component on one side of one end of the clamp body 1.
[0024] Furthermore, the warning components include a warning light 7, an electrical contact A8, an electrical contact B9, a sleeve 10, a guide rod 11, a spring A12, and a limiting plate 13. A warning light 7 is installed on one side of one end of the clamp body 1. A sleeve 10 is installed on the side of the clamp body 1 away from the nut 5. A guide rod 11 is fitted inside the sleeve 10. A limiting plate 13 is installed at one end of the guide rod 11. The limiting plate 13 is made of alloy steel, which has extremely high wear resistance and extends its service life. A spring A12 connected to the limiting plate 13 is installed at one end of the guide rod 11 on the outside. An electrical contact B9 is installed at one end of the guide rod 11 away from the limiting plate 13. An electrical contact A8 that cooperates with the electrical contact B9 is installed at one end of the sleeve 10 on the inside. The warning light 7 can be automatically activated to remind workers when the oilstone processing section is about to run out of oil.
[0025] Furthermore, a guide groove is provided at the bottom of the inner side of the feeding trough 2, and a guide block connected to the guide groove is provided at the bottom of the clamping plate 6 to guide the clamping plate 6 so that the screw 4 cannot drive the clamping plate 6 to rotate.
[0026] Furthermore, a gasket 19 is provided on one side of the clamping plate 6, which can improve the clamping effect on the oilstone, buffer the clamping damage to the oilstone, and prevent the oilstone from breaking.
[0027] Working principle: When replacing the ultra-precision machine oilstone, the oilstone can be inserted into the inner side of the pressure plate 3 and clamping plate 6 in the discharge trough 2. Then, by rotating the screw 4 through the knob, the clamping plate 6 can be moved to one side through the screw 4, clamping the oilstone on one side to fix it. At the same time, when the clamping plate 6 moves to one side, it can drive the guide wheel 15 to roll along the inner side of the trapezoidal groove 20. When the guide wheel 15 is on the high side of the trapezoidal groove 20, the spring B17 is in a relaxed state. When the guide wheel 15 moves to the left, it can roll to the low side of the trapezoidal groove 20, thereby pushing the movable rod 21 to move down. When the clamping plate 6 clamps the oilstone on one side, the movable rod 21 can push the spring B17 to compress. At this time, the elastic force of the spring B17 can push the pressure plate 3 to press tightly against the top of the oilstone, so that the device can fix the side and top surface of the oilstone at the same time, improving the fixing effect of the oilstone.
[0028] When the oilstone is in use, when the oilstone processing section is worn out, the processing surface can push the limit plate 13 to overcome the elastic force of the spring A12 and push the electric contact block B9 to contact the electric contact block A8, thereby automatically activating the warning light 7 to remind the staff so that the oilstone extension section can be adjusted.
[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
