[0016] The following further elaborates and explains the present utility model in combination with specific embodiments and the drawings of the specification:
[0017] Please refer to Figure 1 and Figure 2, A dimensional measurement device for bearings, comprising a machine table 10. A clamping mechanism 20, a handling mechanism 30 and a measuring mechanism 40 are provided on the top surface of the machine table 10. The clamping mechanism 20 includes a clamping guide rail group 21 provided on the top surface of the machine table 10. A measuring table 22 is provided in the middle of the clamping guide rail group 21. A first clamping block 23 and a second clamping block 24 are respectively provided on both sides of the measuring table 22. Both the first clamping block 23 and the second clamping block 24 are slidably connected to the measuring guide rail group 41. A driving motor 25 is provided at one end of the measuring guide rail group 41. The driving motor 25 is used to drive the first clamping block 23 and the second clamping block 24 to move in directions approaching and separating from each other. The handling mechanism 30 is used to handle the bearing to the measuring table 22 and remove the measured bearing from the measuring table 22. The measuring mechanism 40 is used to measure the dimensions of the bearing on the measuring table 22.
[0018] In the above solution, the handling mechanism 30 transports the bearing to be measured to the measuring table 22. The driving motor 25 drives the first clamping block 23 and the second clamping block 24 to move in the direction approaching each other along the clamping guide rail, clamping the bearing on the measuring table 22. The measuring mechanism 40 measures the dimensions of the bearing on the measuring table 22. After the measurement is completed, the clamping mechanism 20 releases the bearing, and then the handling mechanism 30 removes the measured bearing from the measuring table 22. The whole process has a high degree of automation, improves the measurement efficiency, reduces the measurement cost, and can reduce errors and improve accuracy.
[0019] It should be noted that the measuring table 22 can be replaced. Measuring tables 22 with different widths correspond to different batches of bearings. Preferably, the width of the measuring table 22 is smaller than the outer diameter of the bearing to be measured and larger than the inner diameter of the measured bearing.
[0020] Please refer to Figure 1 and Figure 2 , A left - right hand lead screw 26 is rotatably provided along the length direction inside the clamping guide rail group 21. The first clamping block 23 is threadedly connected to the right - hand thread portion of the left - right hand lead screw 26, and the second clamping block 24 is threadedly connected to the left - hand thread portion of the left - right hand lead screw 26. Further, a first gasket is provided on the side of the first clamping block 23 close to the measuring table 22, and a second gasket is provided on the side of the second clamping block 24 close to the measuring table 22.
[0021] In the above solution, when the driving motor starts, the driving motor 25 drives the left - right hand lead screw 26 to rotate, so as to drive the first clamping block 23 and the second clamping block 24 to move in directions approaching or separating from each other, realizing clamping and releasing the bearing. In addition, the first gasket and the second gasket can also play a role in protecting the bearing. Specifically, the top surfaces of the first clamping block 23 and the second clamping block 24 are both higher than the top surface of the measuring table 22.
[0022] Please refer to Figure 1 and Figure 2The transport mechanism 30 includes a three-dimensional moving component 31 and a grabbing component 32. The grabbing component 32 is arranged on the three-dimensional moving component 31. The three-dimensional moving component 31 is used to drive the grabbing component 32 to reciprocate in a three-dimensional direction. The grabbing component 32 is used to grab the bearing. Specifically, the grabbing component 32 is a pneumatic gripper.
[0023] In the above scheme, the three-dimensional moving assembly 31 includes an X-axis linear guide, a Y-axis linear guide, and a Z-axis linear guide. With the cooperation of the three, the grasping assembly 32 can be driven to reciprocate in three-dimensional directions to grasp the bearing. In this embodiment, the grasping assembly 32 is a pneumatic clamp. In other embodiments, the transport mechanism 30 can directly adopt a multi-axis robotic arm.
[0024] Please refer to Figure 1 and Figure 2 The measuring mechanism 40 includes a measuring guide rail group 41, which is arranged parallel to one end of the clamping guide rail group 21. A slide 42 is slidably provided on the measuring guide rail group 41. The slide 42 is transmission-connected to a driving cylinder 43. The driving cylinder 43 is used to drive the slide 42 to reciprocate along the measuring guide rail group 41. A CCD measuring camera 44 is provided on the slide 42, and the CCD measuring camera 44 is located above the measuring platform 22.
[0025] In the above scheme, the driving cylinder 43 can drive the slide 42 to reciprocate along the measuring guide rail, thereby driving the CCD measuring camera 44 to move, so as to measure the bearing. Compared with the manual measurement method, the CCD measuring camera 44 is used to measure the bearing, which is more efficient and the measurement data is more accurate.
[0026] Please refer to Figure 1 A first material tray 11 and a second material tray 12 are respectively disposed on both sides of the clamping guide rail group 21 .
[0027] In the above solution, the first tray 11 is used to place the bearings to be measured, and the second tray 12 is used to place the measured bearings. Specifically, the second tray 12 can also be divided into a qualified area and an unqualified area, and the corresponding bearings are placed in each area.
[0028] The utility model provides a dimension measuring device for bearings. A conveying mechanism conveys a bearing to be measured to a measuring table. A driving motor drives a first clamping block and a second clamping block to move toward each other along a clamping guide rail to clamp the bearing on the measuring table. The measuring mechanism measures the dimension of the bearing on the measuring table. After the measurement is completed, the clamping mechanism releases the bearing, and the measured bearing is conveyed away from the measuring table by the conveying mechanism. The whole process has a high degree of automation, improves measurement efficiency, reduces measurement cost, can reduce errors, and improves accuracy.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
