Specific embodiment

For the content for further appreciating that the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments.

Embodiment 1

A kind of abrasive wheel grinding wheel arc of the present embodiment modifies micro-adjusting mechanism combined with Figure 1 and Figure 2, including is mounted on workbench 400 Diamond pen 100, wherein diamond pen 100 is fixedly mounted on rotating arm 300, the shaft of the rotating arm 300 and servo motor 500 501 are connected.Being operated by servo motor 500 drives rotating arm 300 to rotate, and then diamond pen 100 is driven to rotate, thus to work Grinding wheel to be processed 200 on platform 400 is modified.

Controlling diamond pen 100 by servo motor 500 with shaft 501 is the center of circle, with the central axis of diamond pen 100 away from turning The distance of the central axis of axis 501 is that radius is rotated, so that diamond pen 100 is mechanical-moulded to the finishing of grinding wheel 200, is convenient for Processing, and the motion profile of diamond pen 100 is more smooth, stablizes, and improves the dressing accuracy of grinding wheel 200.

In order to guarantee trimming device finishing grinding wheel 200 accuracy, each component of trimming device before processing, Various parameters design in advance, such as length, height and width parameter.Theoretically, wheel dresser is fixed on After on workbench 400, the revolution highest point of diamond pen 100 and 200 centre of gyration of grinding wheel are in sustained height, but in practical set mistake Cheng Zhong not can avoid the rigging error generated in assembling process, so that the revolution highest point of diamond pen 100 and grinding wheel 200 turn round Center is not in sustained height, and due to the difference of the two and little, the present embodiment offers upper installing hole on rotating arm 300 301, fine adjustment shaft 600 is installed in the upper installing hole 301, diamond pen 100 deviate 600 central axis of fine adjustment shaft be fixed at it is micro- It adjusts on axis 600, and the fine adjustment shaft 600 can be rotated relative to upper installing hole 301, as shown in figure 3, user can pass through rotation Diamond pen 100 adjusts the revolution highest point of diamond pen 100, and spanner or other auxiliary tools also can be used, and rotates fine adjustment shaft 600, and then the position of diamond pen 100 is adjusted, so that the revolution highest point of diamond pen 100 and 200 centre of gyration of grinding wheel In sustained height, is conducive to subsequent diamond pen 100 and arc swing finishing is carried out to grinding wheel 200.In addition, the design of fine adjustment shaft 600 It is dismounted on rotating arm 300 convenient for diamond pen 100.

It is worth noting that transition fit is used between the fine adjustment shaft 600 in the present embodiment and upper installing hole 301, so that When carrying out arc swing finishing to grinding wheel 200, fine adjustment shaft 600 is not easy to rotate in upper installing hole 301 diamond pen 100, And then will not influence diamond pen 100 and turn round highest point, be conducive to going on smoothly for production and processing.

In addition, the distance that diamond pen 100 in the present embodiment deviates 600 central axis of fine adjustment shaft can be with are as follows: 0.25mm, 0.5mm, 0.75mm, 1mm, 2mm, 3mm, 5mm ..., the purpose of structure design need to only guarantee that diamond pen 100 deviates fine adjustment shaft The setting of 600 central axis, fine adjustment shaft 600 rotate, and drive diamond pen 100 to move, so that diamond pen 100 is on rotating arm 300 Position-adjustable, i.e. adjusting diamond pen 100 is relative to the vertical range between the shaft 501 of servo motor 500.Due to this implementation Fine adjustment shaft 600 in example carries out 360 ° of rotations in upper installing hole 301, so that diamond pen 100 can also carry out 360 ° of rotations, Buddha's warrior attendant The distance that pen 100 deviates 600 central axis of fine adjustment shaft is bigger, and the range that diamond pen 100 adjusts is bigger, i.e., diamond pen 100 is opposite The variable of vertical range between the shaft 501 of servo motor 500 is bigger.

Embodiment 2

A kind of abrasive wheel grinding wheel arc of the present embodiment modifies micro-adjusting mechanism, substantially with embodiment 1, the difference is that: this reality The rotating arm 300 applied in example can be vertically mounted in shaft 501, in conjunction with Fig. 1 and 4；Shaft 501 can also be mounted obliquely on On, in conjunction with 5；As long as guaranteeing that servo motor 500 is able to drive diamond pen 100 and is swung, and diamond pen 100 is on perpendicular Movement.

As a preference, the rotating arm 300 in the present embodiment is vertically arranged with shaft 501, convenient for carrying out to grinding wheel 200 It modifies and rotating arm 300 is mounted in shaft 501.

In conjunction with Fig. 1 and Fig. 4, the diameter of diamond pen 100 is greater than the diameter of fine adjustment shaft 600 in order to prevent in the present embodiment, into And not can guarantee deviation 600 central axis of fine adjustment shaft of diamond pen 100 and installed, as a preference, in fine adjustment shaft 600 and gold Mounting blocks 700 are equipped between rigid pen 100, which is fixedly linked with fine adjustment shaft 600, the other end and diamond pen 100 It is fixedly linked, and the distance between central axis of the central axis of diamond pen 100 and fine adjustment shaft 600 is 1mm.
