Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to a bearing-specific grinding machine grinding dimension detection component. Background Technology

[0002] Bearings are key components that provide rotational support through the precise fit between inner and outer rings and rolling elements. Because bearings need to operate stably for extended periods under high speed, heavy loads, or extreme temperature and humidity conditions, the dimensional accuracy, surface roughness, and geometric errors of the inner and outer ring raceways and rolling elements directly affect friction loss, vibration noise, and service life. Therefore, the heat-treated blank needs to be machined at the nanometer level using a diamond grinding wheel on a grinding machine to ensure that the bearing meets the design requirements for dynamic performance and fatigue life. After grinding, the inner and outer rings of the bearing need to be dimensionally inspected.

[0003] Currently, when inspecting the dimensions of the inner and outer rings of bearings, workers place the bearing's inner and outer rings on a testing table and then manually rotate them, observing the changes in the dial indicator readings to achieve the inspection purpose. However, manually rotating the inner and outer rings not only easily leads to hand fatigue, but the contact friction between the inner and outer rings and the surface of the testing table may also increase the risk of surface damage to the inner and outer rings. Utility Model Content

[0004] The purpose of this invention is to provide a grinding dimension detection component for a bearing-specific grinding machine, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A grinding dimension detection component for a bearing-specific grinding machine includes a base. An elastic telescopic component is rotatably mounted on the upper surface of the base. A turntable is mounted at the telescopic end of the elastic telescopic component. Four through slots are arranged in a circular array on the surface of the turntable. A slider is slidably mounted inside each slot. A clamping rod is provided on the upper surface of the slider. A second spring is disposed inside each slot, with its two ends abutting against the inner wall of the slot near the center of the turntable and the slider, respectively. A first wedge block is mounted at the bottom of the slider, and a second wedge block is mounted on the outer surface of the elastic telescopic component corresponding to the first wedge block. A dial indicator is mounted on the upper side of the base via a bracket.

[0007] As can be seen, by fixing the inner and outer rings of the bearing to the surface of the turntable with four clamping rods, and then rotating the turntable to drive the inner and outer rings to rotate for testing, since the inner and outer rings are relatively stationary with respect to the turntable during the testing process, the manual rotation of the inner and outer rings by the testing personnel is avoided, which increases hand fatigue and causes friction damage to the bottom of the inner and outer rings. The results are good.

[0008] Furthermore, the elastic telescopic component includes a sleeve rotatably mounted on the upper surface of the base, a second wedge block mounted on the sleeve, a movable rod slidably mounted inside the sleeve, and the center of the bottom of the turntable connected to the top of the movable rod. A first spring is sleeved on the outer surface of the sleeve, and the two ends of the first spring abut against the second wedge block and the turntable, respectively.

[0009] Furthermore, the surface of the slider has multiple adjustment holes along its length, and the bottom of the clamping rod is provided with a first screw that matches the adjustment holes.

[0010] Furthermore, the bracket has a through slot, an L-shaped plate is inserted inside the through slot, a dial indicator is set on the outside of the L-shaped plate, and fastening bolts are installed on the top of the bracket.

[0011] Furthermore, an installation groove is provided on the outer surface of the L-shaped plate, a second screw is rotatably installed inside the installation groove, a drive block is installed on the outer surface of the second screw, and a dial indicator is installed at the end of the drive block.

[0012] Furthermore, a limit rod is installed inside the through groove, and the slider and the second spring are both sleeved on the outer surface of the limit rod.

[0013] Furthermore, a hexagonal groove is provided at the top of the clamping rod.

[0014] Furthermore, multiple levers are mounted on the side surface of the turntable.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0016] 1. This utility model uses four clamping rods to fix the inner and outer rings of the bearing to the surface of the turntable. Then, the turntable is rotated to drive the inner and outer rings to rotate for testing. Since the inner and outer rings are relatively stationary with respect to the turntable during the testing process, it avoids the situation where the testing personnel manually rotate the inner and outer rings, which increases hand fatigue and causes friction damage to the bottom of the inner and outer rings. The effect is good.

[0017] 2. By setting the adjustment hole and the first screw, the position of the clamping rod can be adjusted, thereby fixing inner and outer rings of different sizes. The height of the elastic telescopic member and the downward pressing distance of the turntable are constant, which is conducive to the miniaturization of the device. Attached Figure Description

[0020] 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.

[0021] Please see Figures 1-6 This utility model provides a bearing-specific grinding machine grinding dimension detection component, including a base 1. An elastic telescopic member 2 is rotatably mounted on the upper surface of the base 1. A turntable 3 is mounted at the telescopic end of the elastic telescopic member 2. Four through slots 301 are arranged in a circular array on the surface of the turntable 3. A slider 302 is slidably mounted inside the through slots 301. A clamping rod 303 is provided on the upper surface of the slider 302. A second spring 306 is provided inside the through slots 301, with both ends of the second spring 306 abutting against the inner wall of the through slot 301 near the center of the turntable 3 and the slider 302, respectively. A first wedge block 304 is mounted at the bottom of the slider 302, and a second wedge block 305 is mounted on the outer surface of the elastic telescopic member 2 corresponding to the first wedge block 304. A dial indicator 5 is mounted on the upper side of the base 1 via a bracket 4.

[0022] During testing, first press down on the turntable 3. The squeezing action of the second wedge block 305 and the first wedge block 304 causes the four clamping rods 303 to retract simultaneously towards the circular direction of the turntable 3. Then, the inner and outer rings of the bearing can be fitted onto the outside of the four clamping rods 303. Next, the elastic telescopic member 2 pushes the turntable 3 upwards to reset it. Under the elastic thrust of the second spring 306, the four clamping rods 303 move away from the center of the turntable 3 and press against the inner walls of the inner and outer rings for fixation. The turntable 3 then causes the inner and outer rings to rise, bringing their surfaces into contact with the probe of the dial indicator 5. Rotating the turntable 3 then rotates the inner and outer rings to perform the test. Since the inner and outer rings remain relatively stationary with respect to the turntable 3 during testing, manual rotation of the inner and outer rings by the testing personnel is avoided, preventing hand fatigue and friction damage to the bottom of the inner and outer rings. This method is highly effective.

[0023] Preferably, the elastic telescopic member 2 includes a sleeve 201 rotatably mounted on the upper surface of the base 1, a second wedge block 305 mounted on the sleeve 201, a movable rod 202 slidably mounted inside the sleeve 201, and the center of the bottom of the turntable 3 connected to the top of the movable rod 202. A first spring 203 is sleeved on the outer surface of the sleeve 201, and the two ends of the first spring 203 abut against the second wedge block 305 and the turntable 3 respectively.

[0024] The sleeve 201, movable rod 202 and first spring 203 are arranged to achieve elastic extension and contraction. Since the movable rod 202 is limited and slidably connected to the sleeve 201, the angle of the movable rod 202 can be limited, so that the movable rod 202 cannot rotate relative to the sleeve 201, thus ensuring that the first wedge block 304 always corresponds to the second wedge block 305.

[0025] Preferably, the surface of the slider 302 is provided with a plurality of adjustment holes 3021 along its length direction, and the bottom of the clamping rod 303 is provided with a first screw 3031 that is adapted to the adjustment holes 3021.

[0026] By adjusting the hole 3021 and the first screw 3031, the position of the clamping rod 303 can be adjusted, thereby fixing inner and outer rings of different sizes. The height of the elastic telescopic member 2 and the downward pressing distance of the turntable 3 are constant, which is conducive to the miniaturization of the device.

[0027] Preferably, the bracket 4 has a through groove 401, an L-shaped plate 402 is inserted inside the through groove 401, a dial indicator 5 is set on the outside of the L-shaped plate 402, and a fastening bolt 403 is installed on the top of the bracket 4.

[0028] After loosening the fastening bolt 403, the position of the dial indicator 5 can be adjusted. Finally, tighten the fastening bolt 403 to fix the position of the dial indicator 5, so that the inner and outer rings of different diameters can be tested.

[0029] Preferably, the outer surface of the L-shaped plate 402 is provided with a mounting groove 6, a second screw 601 is rotatably mounted inside the mounting groove 6, a drive block 602 is mounted on the outer surface of the second screw 601, and a dial indicator 5 is mounted on the end of the drive block 602.

[0030] When the second screw 601 is turned, the drive block 602 can be raised or lowered under the action of the threaded connection, thereby adjusting the height of the dial indicator 5 so that it can detect inner and outer rings of different thicknesses.

[0031] Preferably, a limiting rod 307 is installed inside the through groove 301, and the slider 302 and the second spring 306 are both sleeved on the outer surface of the limiting rod 307.

[0032] The limiting rod 307 provides support for the second spring 306, preventing it from bending under gravity.

[0033] Preferably, the top of the clamping rod 303 is provided with a hexagonal groove.

[0034] A hex wrench can be used to assemble and disassemble the clamping rod 303.

[0035] Preferably, multiple levers are mounted on the side surface of the turntable 3.

[0036] The addition of a hand grip point makes it easier to rotate turntable 3.
