[0023] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific embodiments:

[0024] As Figures 1-5As shown in the figure, the utility model provides a measuring instrument for the raceway of the outer ring of a robot bearing, which includes a measuring platform 1 and a measuring device 204. A guiding groove 100 is provided on the measuring platform 1, and an adjusting component 3 is arranged in the guiding groove 100. The adjusting component 3 includes a screw rod 302 and a fixing rod 306. A first placing plate 5, a second placing plate 6 and a third placing plate 7 are fixedly installed at the top of the fixing rod 306. Chute grooves 500 are provided on both sides of the first placing plate 5, the second placing plate 6 and the third placing plate 7, and a first top plate 501, a second top plate 601 and a third top plate 701 are respectively fixedly installed at the tops. A limiting component 8 is arranged between several chute grooves 500. The limiting component 8 includes several sliding rods 801, several compression springs 802, a first extrusion plate 803, a second extrusion plate 804 and a third extrusion plate 805. The first extrusion plate 803, the second extrusion plate 804 and the third extrusion plate 805 are respectively slidably sleeved on several sliding rods 801 and squeeze the corresponding compression springs 802 when moving;

[0025] A mounting seat 201 is fixedly installed at the top of the measuring platform 1. A mounting rod 202 is fixedly installed at the top of the mounting seat 201. A sleeve rod 203 is fixedly sleeved on the outer wall of the mounting rod 202. The measuring device 204 is arranged at one end of the sleeve rod 203.

[0026] Before measuring the bearing, the staff first selects one of the first placing plate 5, the second placing plate 6 and the third placing plate 7 according to the diameter of the bearing. If the bearing needs to be placed on the top of the first placing plate 5, at this time, the first extrusion plate 803 is pulled. When the first extrusion plate 803 moves, it can slide on two sliding rods 801 and squeeze two of the compression springs 802. After the first extrusion plate 803 moves a certain distance, the staff places the bearing on the first placing plate 5, and then slowly releases the handle 807, so that the pull rod 806 and the first extrusion plate 803 can move in the opposite direction under the action of the two compression springs 802, and after pushing the bearing a certain distance, they cooperate with the first top plate 501 to squeeze and limit the bearing, which can apply a certain limiting effect to the bearing during the bearing measurement, reduce the probability of the bearing being displaced and falling off during the measurement process, and further reduce the probability of the bearing being damaged, and improve the measurement efficiency;

[0027] After the bearing is clamped, the staff rotates the screw rod 302. When the screw rod 302 rotates, it drives the first placing plate 5, the second placing plate 6 and the third placing plate to move through the fixing rod 306, so that the first placing plate 5 moves to the measurement area. Then the fixing rod 306 is rotated. After the fixing rod 306 rotates, it drives the first placing plate 5, the second placing plate 6 and the third placing plate 7 to rotate uniformly, so that the bearing rotates to the state to be measured. Then the measuring device 204 is started to measure the bearing. By limiting and installing bearings of different sizes, bearings of different sizes can be measured, and there is no need to replace the equipment when measuring bearings of different sizes, reducing the time required for measurement, and improving work efficiency and applicability;

[0028] The measuring device 204 is prior art and will not be explained here.

[0029] As Figures 3-4 shown, in one embodiment, the limiting component 8 further includes a plurality of pull rods 806 and a plurality of handles 807. One ends of the plurality of compression springs 802 are all connected to the sliding groove 500, and the other ends are respectively connected to the first pressing plate 803, the second pressing plate 804 and the third pressing plate 805. The plurality of compression springs 802 are respectively sleeved on the plurality of sliding rods 801. One ends of the plurality of pull rods 806 are respectively fixedly installed on the first pressing plate 803, the second pressing plate 804 and the third pressing plate 805. The plurality of handles 807 are respectively fixedly connected to the plurality of pull rods 806.

[0030] By providing the pull rods 806 and the handles 807, the operation difficulty is simplified, the physical strength consumed by the staff during operation can be effectively reduced, and the operation efficiency and applicability are improved.

[0031] As Figures 2-3 shown, in one embodiment, the adjusting component 3 further includes a first motor 301, a rotating shaft, a slider 303, a bearing plate 304 and a second motor 305. One end of the screw rod 302 penetrates through the measuring platform 1 and is fixedly connected to the output end of the first motor 301. The other end of the screw rod 302 is rotatably connected to the guide groove 100. The slider 303 is threadedly sleeved on the screw rod 302 and both sides thereof are in contact with the guide groove 100. The bearing plate 304 is fixedly installed on the top of the slider 303. The second motor 305 is fixedly installed at one end of the bearing plate 304. One end of the rotating shaft is fixedly connected to the output end of the second motor 305 and the other end is rotatably connected to the bearing plate 304. The fixing rod 306 is fixedly sleeved on the rotating shaft.

[0032] Setting the first motor 301 can effectively control the number of rotation turns of the screw rod 302, and the second motor 305 can accurately control the rotation amplitude of the bearing plate 304 and the fixing rod 306, improving the accuracy of the device and thus improving the measurement effect.

[0033] As Figure 2 shown, in one embodiment, a fixing plate 4 is fixedly installed at the side end of the measuring platform 1. The first motor 301 is fixedly installed at one end of the fixing plate 4.

[0034] The fixing plate 4 can cooperate with the measuring platform 1 to enhance the fixing effect on the first motor 301, reduce the probability of the first motor 301 falling off during operation, and extend the service life of the device.

[0035] As Figure 3As shown, in one embodiment, the amplitudes formed on one side of the first top plate 501, the second top plate 601, and the third top plate 701 are different, and the amplitudes formed inside the first pressing plate 803, the second pressing plate 804, and the compression spring 802 are different. Arc-shaped limiting strips 10 with different sizes are fixedly installed on the tops of the first top plate 501, the second top plate 601, and the third top plate 701 respectively.

[0036] The different amplitudes formed on the first top plate 501, the second top plate 601, and the third top plate 701 are used to place bearings with different sizes, improving applicability. The arc-shaped limiting strips 10 can further limit the bearings, improving the limiting effect.

[0037] The working principle of the robot bearing outer ring raceway measuring instrument will be specifically described below:

[0038] Before measuring the bearing, the staff first selects one from the first placing plate 5, the second placing plate 6, and the third placing plate 7 according to the diameter of the bearing, and then holds the corresponding handle 807 and pulls the corresponding pull rod 806. If it is necessary to place the bearing on the top of the first placing plate 5, at this time, the pull rod 806 can pull the first pressing plate 803 to move horizontally. When the first pressing plate 803 moves, it can slide on the two sliding rods 801 and squeeze two of the compression springs 802. After the first pressing plate 803 moves a certain distance, the staff places the bearing on the first placing plate 5, and then slowly releases the handle 807, which can make the pull rod 806 and the first pressing plate 803 move in the opposite direction under the action of the two compression springs 802, and cooperate with the first top plate 501 to squeeze and limit the bearing after pushing the bearing a certain distance, which can apply a certain limiting effect to the bearing during measurement, reduce the probability of the bearing being displaced and falling off during the measurement process, and further reduce the probability of the bearing being damaged, improving the measurement efficiency;

[0039] After the bearing is clamped, the staff starts the first motor 301. When the output end of the first motor 301 rotates, it drives the screw rod 302 to rotate. When the screw rod 302 rotates, it is in threaded cooperation with the slider 303, making the slider 303 slide in the guide groove 100 and driving the bearing plate 304 to move horizontally. When the bearing plate 304 drives the first placing plate 5 to move to the measurement area, the first motor 301 is turned off, and the second motor 305 is started. When the output end of the second motor 305 rotates, it drives the rotating shaft and the fixed rod 306 to rotate. After the fixed rod 306 rotates, it drives the first placing plate 5, the second placing plate 6, and the third placing plate 7 to rotate uniformly, so that the bearing rotates to the state to be measured, and then the measuring instrument 204 is started to measure the bearing. By limiting and installing bearings with different sizes, bearings with different sizes can be measured, and there is no need to replace the equipment when measuring bearings with different sizes, reducing the time required for measurement, and improving work efficiency and applicability.

[0040] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made thereto, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and idea of the present utility model are all within the protection scope of the present utility model.
