[0002] During the grinding wheel dressing or grinding process, it is usually necessary to spray cooling water in order to cool the dressing pen or the workpiece being ground and rinse the grinding wheel surface.

[0003] However, since the grinding wheel rotates at high speed during dressing or grinding, the cooling water will splash around after contacting the grinding wheel, causing the cooling water and sand to splash onto the grinding wheel dresser. In order to prevent the cooling water from splashing onto the dresser through the long strip hole of the grinding frame, a movable multi-layer water baffle is often installed at the long strip hole of the grinding frame, and strip holes of varying lengths are opened on the multi-layer water baffle. The multi-layer water baffle is superimposed and covered to cover the long strip dressing hole of the grinding frame, and the hole opened on the outermost water baffle is appropriately reserved with a gap of 1 to 2 mm according to the shape of the dressing pen holder, so as to facilitate the dressing pen holder to pass through. However, the existence of this gap makes it easy for a small amount of high-speed splashing cooling water to pass through the gap and fall on the grinding wheel dresser, thereby affecting the use accuracy, life and appearance of the dresser.

[0031] In the present invention, unless otherwise clearly defined, the words "set", "install", "connect" and the like should be understood in a broad sense, for example, they can be directly connected or indirectly connected through an intermediate medium; they can be fixedly connected or detachably connected or integrally formed; they can be mechanically connected or electrically connected or able to communicate with each other; they can be the internal connection of two elements or the interaction relationship between two elements. Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0032] Reference Figures 1 to 3 As shown, a grinding wheel dressing water retaining structure of the utility model comprises a grinding frame 01, a dressing pen holder 07 arranged on the grinding frame 01, and a grinding wheel 12 located on one side of the grinding frame 01, a dressing pen facing the circumferential end of the grinding wheel 12 is installed on the dressing pen holder 07, an opening is opened on the grinding frame 01 for the dressing pen holder 07 to extend into, and further comprises:

[0033] A protective cover 16, wherein the protective cover 16 is disposed on the dressing pen holder 07 and allows the dressing pen to expose the axial front end of the protective cover 16, and the protective cover 16 is an axially retractable structure, and can be axially retracted when the dressing pen approaches or moves away from the circumferential end of the grinding wheel 12;

[0034] A water baffle 05, covering the opening and connected to the axial rear end of the protective cover 16;

[0035] The support structure is installed on the grinding frame 01 and is used to support the water retaining plate 05 to move along the width direction of the grinding wheel 12.

[0036] It can be understood that when the dressing pen is dressing the grinding wheel 12, in order to dress the entire width of the grinding wheel 12, the dressing pen can move left and right along the width direction of the grinding wheel 12. At the same time, as the surface of the grinding wheel 12 is dressed and the grinding wheel 12 is threshed, the diameter of the grinding wheel 12 will become smaller and smaller. In order to match the change in the diameter of the grinding wheel 12 so that the grinding wheel 12 can be dressed, the dressing pen can move forward and backward in the feeding direction (i.e., the axial direction of the protective cover 16). At this time, the protective cover 16 performs axial telescopic movement with the dressing pen feeding movement. A hole for the dressing pen holder 07 to pass through is provided on the water baffle 05 corresponding to the opening.

[0037] An axially retractable protective cover 16 is provided to cover the trimming pen holder 07. The protective cover 16 is seamlessly installed among the trimming pen holder 07 and the water baffle plate 05 to block splashing cooling water, thereby ensuring that the protective cover 16 can block water when the trimming pen reciprocates left and right and feeds forward and backward, thereby avoiding the problem of cooling water passing through the hole of the water baffle plate 05 caused by directly installing the trimming pen holder 07 in the hole of the water baffle plate 05.

[0038] Specifically, the trimming pen is a diamond pen.

[0039] In one embodiment, referring to Figure 4 As shown, the protective cover 16 includes a tubular telescopic portion 161 and a front connecting flange 162 and a rear connecting flange 163 connected to the two axial ends of the telescopic portion 161; specifically, a circular telescopic protective cover 16 can be used.

[0040] In one embodiment, it further comprises a support plate 18 connected to the trimming pen holder 07 and connected to the front connecting flange 162. A first connecting column 17 (such as a screw) is connected between the support plate 18 and the front connecting flange 162.

[0041] In one embodiment, a connecting piece is further included, and an annular step is formed between the rear connecting flange 163 and the telescopic portion 161, and the front support ring 15 and the rear support ring 13 are respectively abutted at both ends of the annular step in the circumferential direction, and the connecting piece passes through and connects the water baffle 05, the front support ring 15 and the rear support ring 13 in sequence. The connecting piece can be a screw.

[0042] Specifically, the inner hole of the front support ring 15 is provided with a contact step suitable for abutting and matching with the annular step.

[0043] In one embodiment, the water baffle 05 is a multi-layered superimposed structure, specifically comprising a first water baffle 051, a second water baffle 06 and a third water baffle 08 superimposed on each other.

[0044] In one embodiment, the support structure includes a pressing plate 04 mounted on the outer wall of the grinding frame 01 and a plurality of bearings 03 mounted through the pressing plate 04 and arranged in a straight line and extending along the width direction of the grinding wheel 12 .

[0045] In one embodiment, a fixing member 02 is further included, and a pressure plate 04 is arranged outside all the bearings 03, and the fixing member 02 passes through the pressure plate 04 and correspondingly installs each bearing 03 on the outer wall of the grinding frame 01, and the bottom of the water retaining plate 05 is located between the pressure plate 04 and the outer wall of the grinding frame 01. The fixing member 02 can be a screw.

[0046] Specifically, the outer wall of the grinding frame 01 is provided with an upper limit baffle 10 for limiting the axial movement of the water baffle 05. A second connecting column 09 (such as a screw) is connected between the upper limit baffle 10 and the outer wall of the grinding frame 01.

[0047] In one embodiment, a pressure cover 11 located above the grinding wheel 12 is disposed on the upper portion of the grinding frame 01 .

[0048] When dressing the grinding wheel 12, in the width direction of the grinding wheel 12, the dressing pen holder 07, the front support ring 15, the rear support ring 13, the protective cover 16, and the water baffle 05 form a whole, and are supported on the bearing 03 so as to be movable; in the radial direction of the grinding wheel 12, the front support ring 15 and the rear support ring 13 remain in position, and the protective cover 16 extends and retracts along the forward and backward movement with the feeding movement of the dressing pen, thereby being able to completely protect the cooling water of the grinding wheel 12 in the dressing direction.

[0049] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
