DETAILED DESCRIPTION

[0024] The scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. In addition, the descriptions of "first", "second", etc. in the utility model are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0025] In view of the technical defects existing in the related art, the utility model provides a fastening accessory, please refer to Figures 1 to 6 The fastening accessory includes: a first clamping arm 100, a second clamping arm 200, a driving device 300, a container 400 and a water pump 500, wherein a cooling cavity 110 is arranged inside the first clamping arm 100, and the shape of the cooling cavity 110 can be a cylinder, a square or other shapes, which is not specifically limited here; the surface of the first clamping arm 100 is provided with a liquid inlet 111 and a liquid outlet 112 connected to the cooling cavity 110; the liquid inlet 111 is used to input coolant into the cooling cavity 110, and the liquid outlet 112 is used to discharge the coolant in the cooling cavity 110.

[0026] The second clamping arm 200 can slide in a direction close to or away from the first clamping arm 100; the driving device 300 is installed on the first clamping arm 100, and the driving device 300 is used to drive the second clamping arm 200 to slide; thus, under the action of the driving device 300, the second clamping arm 200 can slide in a direction close to the first clamping arm 100 to clamp the aluminum alloy plate between the first clamping arm 100 and the second clamping arm 200.

[0027] The driving device 300 can be driven to move the second clamping arm 200 manually or electrically. For example, the driving device 300 includes a cam and a rotating handle arranged on the cam. The rotating handle is manually rotated to drive the cam to rotate so as to squeeze the second clamping arm 200 to slide toward the first clamping arm 100. The outer contour of the cam abuts against the second clamping arm 200 so that the second clamping arm 200 and the first clamping arm 200 clamp the aluminum alloy plate together. In this way, the second clamping arm 200 can be driven to move in a reliable manual driving manner.

[0028] In another embodiment, the driving device 300 includes a motor and a screw rod. The motor is fixedly mounted on the first clamping arm 100. The screw rod is connected to the output shaft of the motor. A threaded hole 220 is provided through the second clamping arm 200. The screw rod is threadedly connected to the threaded hole 220. In this way, the motor can drive the screw rod to drive the second clamping arm 200 to slide toward the direction close to the first clamping arm 100, thereby clamping the aluminum alloy plate.

[0029] The container 400 is used to hold the coolant, which can perform heat exchange with the first clamping arm 100, and then the first clamping arm 100 performs heat exchange with the aluminum alloy plate in contact with it. The container 400 is connected to the liquid outlet 112, and the water pump 500 is arranged on the container 400. The water inlet of the water pump 500 is connected to the container 400, and the water outlet of the water pump 500 is connected to the liquid inlet 111. In this way, the water pump 500 can drive the coolant in the container 400 to enter the cooling cavity 110 along the liquid inlet 111, and the coolant passes through the cooling cavity 110 and is discharged from the liquid outlet 112 into the container 400, so that the cooling speed of the first clamping arm 100 can be increased.

[0030] The coolant can be water, ice water or other liquids, and is not specifically limited here.

[0031] Through the technical solution of the utility model, a cooling cavity 110 is provided in the first clamping arm 100 of the fastening accessory, and the cooling liquid can be filled into the cooling cavity 110 through the water pump 500. The coolant enters the cooling cavity 110 through the liquid inlet 111 of the first clamping arm 100, and then flows into the container 400 for containing the coolant from the liquid outlet 112. In this way, the driving device 300 drives the second clamping arm 200 to slide in the direction close to the first clamping arm 100 to clamp the aluminum alloy plate. Subsequently, the heat energy generated during the cutting of the aluminum alloy plate is partially cooled by the coolant in the first clamping arm 100, thereby avoiding deformation of the clamping part due to overheating and under the action of the clamping force, thereby ensuring the flatness of the surface of the aluminum alloy plate.

[0032] It should be noted that, in other embodiments, the cooling cavity 110 may be disposed in the second clamping arm 200 , or the cooling cavity 110 may be disposed in both the first clamping arm 100 and the second clamping arm 200 .

[0033] In order to enhance the cooling of the first clamping arm 100 by the coolant, in the present embodiment, the cooling cavity 110 is disposed adjacent to the side of the first clamping arm 100 facing the second clamping arm 200 , so that the coolant can quickly contact the heat conducted from the first clamping arm 100 .

[0034] Please continue reading Figure 3 In order to further improve the cooling effect, in the present embodiment, the cooling cavity 110 is arranged in the first clamping arm 100 in the form of an "S"-shaped curved tube cavity, the liquid inlet 111 is located at one end of the curved tube cavity, and the liquid outlet 112 is located at the other end of the curved tube cavity. In this way, the flow path of the coolant can be extended, the time when the coolant is in the first clamping arm 100 can be extended, and the cooling effect of the coolant on the first clamping arm 100 can be improved.

[0035] In order to further prolong the time that the coolant stays in the first clamping arm 100, a plurality of raised ribs 170 are provided on the bottom wall of the curved tube cavity, and each raised rib 170 is arranged at intervals along the extension direction of the curved tube cavity. These raised ribs 170 can block the flow of the coolant to reduce the flow rate of the coolant and increase the time that the coolant stays in the first clamping arm 100.

[0036] To facilitate the formation of the cooling cavity 110, in some embodiments, a connecting groove 120 is recessed on the surface of the first clamping arm 100 facing the second clamping arm 200, a cooling groove is recessed at the bottom of the connecting groove 120, and the first clamping arm 100 also includes a heat conducting plate 130, which is sealed and connected to the connecting groove 120 to close the cooling groove. In this way, a cooling groove can be formed in the connecting groove 120, and then the cooling groove and the heat conducting plate 130 are connected to the connecting groove 120 to form the cooling cavity 110.

[0037] In addition, the heat conducting plate 130 is made of a metal material with excellent heat conduction, such as copper alloy, magnesium alloy, etc. The heat conducting plate 130 is located at the position of clamping the aluminum alloy plate, and can directly transfer the heat of cutting the aluminum alloy plate to the coolant.

[0038] It should be noted that, in order to ensure the sealing of the cooling cavity 110 , the heat conducting plate 130 and the connecting groove 120 may be connected by welding.

[0039] In addition, each protruding rib 170 extends out of the notch of the cooling groove, and a plurality of positioning grooves 131 are recessed on the side of the heat conducting plate 130 facing the cooling groove, and each positioning groove 131 corresponds to the protruding rib 170. In this way, each protruding rib 170 and each positioning groove 131 form a plug-in fit, which facilitates the positioning and installation of the heat conducting plate 130 and prevents the heat conducting plate 130 from moving when it is welded to the connecting groove 120. In addition, since one end of the protruding rib 170 is connected to the cooling groove and the other end of the protruding rib 170 is plug-in fit with the heat conducting plate 130, the two ends are fixed, which can improve the overall structural strength of the protruding rib 170 and prevent deformation caused by being washed by the coolant.

[0040] In a specific implementation, a gap is left between the protruding rib 170 and the two side walls of the cooling groove to allow the coolant to flow through.

[0041] Preferably, the material of the raised rib 170 is a heat-conducting material, such as copper alloy, magnesium alloy, etc. Since the raised rib 170 is in contact with the heat-conducting plate 130, heat exchange can be performed between the two, and the portion of the raised rib 170 located in the cooling groove can be fully in contact with the coolant. In other words, the raised rib 170 can perform heat exchange between the coolant and the heat-conducting plate 130. Compared with the method of only allowing the heat-conducting plate 130 to exchange heat with the coolant at the notch of the cooling groove, the provision of the raised rib 170 is beneficial to increasing the area for heat exchange between the structure and the coolant, thereby improving the heat exchange efficiency.

[0042] In some embodiments, the first clamping arm 100 is provided with two protruding columns 140 , and the second clamping arm 200 is provided with guide holes 210 corresponding to the two protruding columns 140 , and the two protruding columns 140 are inserted into the corresponding guide holes 210 ; in this arrangement, the second clamping arm 200 can slide under the guidance of the two protruding columns 140 .

[0043] Furthermore, the first clamping arm 100 is provided with a mounting hole 150, and the second clamping arm 200 is provided with a threaded hole 220 at a position corresponding to the mounting hole 150, and the driving device 300 includes a screw rod 310, one end of which is rotatably mounted in the mounting hole 150, and the other end of the screw rod 310 is threadedly engaged with the threaded hole 220. In addition, the driving device 300 also includes a handle 330, which is provided at one end of the screw rod 310 away from the second clamping arm 200. The operator can drive the screw rod 310 to rotate by rotating the handle 330, thereby causing the second clamping arm 200 to slide in a direction close to or away from the first clamping arm 100.

[0044] In addition, in order to prevent the screw rod 310 from coming out of the assembly hole 150, in some embodiments, a limiting hole 160 is provided through the inner peripheral wall of the assembly hole 150, and an annular groove 311 extending along its circumferential direction is recessed on the outer peripheral wall of one end of the screw rod 310 located in the assembly hole 150, and the driving device 300 further includes a limiting column 320, which is disposed in the limiting hole 160 and at least partially located in the annular groove 311. Through the action of the limiting column 320, the screw rod 310 can be limited on the first clamping arm 100.

[0045] The above description is only a partial or preferred embodiment of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
