It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.
[0029] The following is attached to the instruction manual Figure 1 and attached Figure 2 , a wire clamp for a sand wire cutting machine of the utility model is introduced.
[0030] In one embodiment, if Figure 1 and Figure 2 As shown, the wire clamp for the sand wire cutting machine includes a base 1, a wire clamp assembly, a rotating shaft 4 and a fixing pin 5.
[0031] The base 1 is used to be fixed near the wire groove of the abrasive wheel of the abrasive wire cutting machine to facilitate hanging the abrasive wire on the abrasive wheel.
[0032] The wire clamping assembly is provided with a wire clamping groove 3 for clamping the sand wire. The cross-sectional area of the notch of the wire clamping groove 3 is slightly smaller than the cross-sectional area of the sand wire to be clamped, so as to facilitate clamping and fixing the sand wire.
[0033] The rotating shaft 4 is disposed on the base body 1 , and the wire clamping assembly is rotatably disposed on the rotating shaft 4 .
[0034] The base body 1 is provided with a pin hole for the fixing pin 5 to pass through, and the fixing pin 5 is used to fix the wire clamping assembly on the base body 1 .
[0035] When in use, the base 1 is fixed near the sanding wheel of the sanding wire cutting machine. When the sanding wire is hung on the sanding wheel, one end of the sanding wire is first fixed, and the other end is passed around the initial wire groove of the sanding wheel. After passing, the sanding wire is passed through the wire clamping groove 3 and tightened, and then clamped by the wire clamping assembly, so that the other end of the sanding wire continues to pass around the next wire groove. After passing, the wire clamping assembly is released, and the other end of the sanding wire passes through the wire clamping groove 3 again and is pulled in, and is clamped by the wire clamping assembly. This is repeated until all the wire grooves are passed. After the winding is completed, the wire clamping assembly no longer clamps the sanding wire, and then the wire clamping assembly is rotated around the rotating shaft 4 to avoid the sanding wire, and then the wire clamping assembly is fixed by the fixing pin 5, so that the sanding wire will not be disturbed by the wire clamping assembly during the working process. Since the sanding wire is tightened and clamped by the wire clamping assembly during the hanging process, the sanding wire that has passed the wire groove is not easy to get out of the wire groove, thereby improving the hanging efficiency and thus improving the production efficiency.
[0036] In one of the embodiments, a fixing hole 2 is provided on the base 1, through which the wire cutter wire clamp can be fixed near the sanding wheel groove of the sanding wire cutter by using a bolt and nut assembly.
[0037] Since sand wires of different sizes may be used in the actual production process, in one embodiment, there are multiple clamping grooves 3, and the cross-sectional areas of the notches of the multiple clamping grooves 3 are different, so that when in use, the corresponding clamping groove 3 can be selected according to the size of the sand wire to clamp the sand wire, and the application range is wide. Specifically, in this embodiment, there are three clamping grooves 3. In other embodiments, the clamping grooves 3 can also be set to one, two, four or five.
[0038] In one of the embodiments, in order to fix the wire clamping assembly, a first fixing hole 2 and a second fixing hole 2 are provided on the wire clamping assembly, and the fixing pin 5 is used to be inserted into the first fixing hole 2 or the second fixing hole 2 .
[0039] Specifically, when the wire clamping groove 3 on the wire clamping assembly is used to clamp the sand wire, the pin hole is aligned with the first fixing hole 2, and then the fixing pin 5 is inserted into the first fixing hole 2, so that the sand wire will not rotate around the rotating shaft 4, so as to facilitate and stably clamp the sand wire and not easily interfere with the wire hanging process. When the wire hanging is completed, the fixing pin 5 is pulled out, and then the wire clamping assembly is rotated around the rotating shaft 4, so that the pin hole is aligned with the second fixing hole 2, and then the fixing pin 5 is inserted into the second fixing hole 2, so that the sand wire will not rotate around the rotating shaft 4 to avoid the sand wire, and then the fixing pin 5 is used to fix the wire clamping assembly, so that the sand wire will not be interfered by the wire clamping assembly during the working process.
[0040] Further, in one embodiment, the fixing pin 5 includes a fixing portion and an operating portion, the fixing portion is inserted into the base 1, and the operating portion is located outside the base 1. When in use, the fixing pin 5 can be conveniently pulled out by pinching the operating portion with fingers.
[0041] In order to prevent the fixing pin 5 from accidentally falling off, in one embodiment, a fixing nut 6 is provided on the base 1, and the fixing nut 6 is aligned with the pin hole. The fixing portion has an external thread that is threadedly matched with the fixing nut 6. The fixing pin 5 can be firmly fixed to the base 1 by threaded matching.

[0045] Specifically, a notch is provided on the rotating block 7, the fixed block 8 is fixed at the notch, and grooves are provided on the mutually abutting sides of the notch and the fixed block 8 to enclose the wire clamping groove 3. In this embodiment, three grooves are provided on the side of the notch, and three grooves are also provided on the corresponding side of the fixed block 8, thereby enclosing three wire clamping grooves 3.
[0046] Further, in one embodiment, in order to fix the fixing block 8, the clamping assembly further includes a threaded fixing member 9, the rotating block 7 is provided with a threaded hole for threadably cooperating with the threaded fixing member 9, and the fixing block 8 is provided with a through hole for the threaded fixing member 9 to pass through, and the fixing block 8 can be fixed to the rotating block 7 through the threaded fixing member 9 to clamp the sand wire. Specifically, the threaded fixing member 9 is a bolt.
[0047] Furthermore, in order to facilitate the screwing of the threaded fixing member 9 , in one embodiment, a knob 10 is provided at the end of the threaded fixing member 9 .
[0048] In one embodiment, in order to accurately fix the fixed block 8 at the corresponding position, the rotating block 7 is provided with two positioning pins 11 for positioning the fixed block 8, and the fixed block 8 is provided with two positioning holes corresponding to the positioning pins 11. When in use, the two positioning pins 11 are plugged and matched with the two positioning holes, so that the fixed block 8 can be positioned at an accurate position, so that the enclosed wire clamping groove 3 is not easy to deviate, and thus it is not easy to damage the sand wire.
[0049] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
