[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] like Figure 1-4 A flange nut anti-loosening tapping device shown includes a fixing plate 100, a pad 200 is provided in the middle of the front end of the fixing plate 100, a left clamp 300 and a right clamp 400 are hinged on both sides of the front end of the fixing plate 100, the middle parts of the left clamp 300 and the right clamp 400 are hinged on the fixing plate 100, the front ends of the left clamp 300 and the right clamp 400 are used to clamp the nut 800 to be tapped, and the rear ends of the left clamp 300 and the right clamp 400 are used as control ends, and a pair of left cylinders 500 and right cylinders 600 cooperating with the left clamp 300 and the right clamp 400 are provided on both sides of the fixing plate 100, the piston rod of the left cylinder 500 is used to push the left clamp 300 forward, and the piston rod of the right cylinder 600 is used to push the right clamp 400 forward.
[0021] Specifically, the front ends of both sides of the fixing plate 100 extend forward to form mounting parts of the left clamp 300 and the right clamp 400. In the present embodiment, a groove is provided at the mounting part, and the middle parts of the left clamp 300 and the right clamp 400 are arranged in the groove and are hinged to the mounting part through a pin shaft. A groove cooperating with the pad 200 is provided at the front end of the fixing plate 100, and the pad 200 is installed in the groove. The pad 200 is used to cooperate with the tapping machine and can be replaced as needed. The front ends of the left clamp 300 and the right clamp 400 can be designed into an L-shaped structure as needed to facilitate the clamping of the flange nut 800.
[0022] It should be noted that during operation, when the flange nut 800 to be processed is inserted between the left clamp 300, the right clamp 400 and the pad 200, the left cylinder 500 and the right cylinder 600 are controlled to work, and the cylinder piston rods are pushed out to push the control ends of the left clamp 300 and the right clamp 400 forward, so that the front ends of the left clamp 300 and the right clamp 400 clamp the processed flange nut 800, thereby solving the problem of beveled teeth caused by the existing loose clamping.
[0023] Furthermore, it also includes a pair of left springs 901 and right springs 902 arranged on both sides of the fixed plate 100 and cooperating with the left clamp 300 and the right clamp 400. When the left clamp 300 and the right clamp 400 are in the open state, the left spring 901 and the right spring 902 are in a stretched state.
[0024] Specifically, relative to the left cylinder 500 and the right cylinder 600 which are arranged at the rear end of the control end of the left clamp 300 and the right clamp 400, the left spring 901 and the right spring 902 are arranged in front of the control end of the left clamp 300 and the right clamp 400, and one end of the left spring 901 and the right spring 902 is connected to the fixing device, and the other end is connected to the control end of the left clamp 300 and the right clamp 400.
[0025] Furthermore, when the left spring 901 and the right spring 902 are in a loosened state, a gap is left between the front ends of the left clamp 300 and the right clamp 400 and the cushion block 200 .
[0026] It should be noted that in the initial state, the two springs are in a loosened state. At this time, there is a gap between the front ends of the left clamp 300 and the right clamp 400 and the pad 200 to accommodate a nut 800, but it is not clamped. The position can be adjusted appropriately as needed; if there is no gap, the nut 800 will not be able to enter, thereby affecting the tapping process.
[0027] During operation, since the nut 800 will be brought out when the tap is withdrawn, the cylinder piston rod has been retracted at this time, and two springs are designed to help the clamp to reset.
[0028] Furthermore, the fixing plate 100 is mounted on the slider 700 , the left clamp 300 and the right clamp 400 are mounted on the slider 700 and are located on both sides of the fixing plate 100 , and the left spring 901 and the right spring 902 are also mounted on the slider 700 .
[0029] Specifically, two long plates are provided on the slider 700, and two cylinders are installed at the rear end of the long plates through two mounting plates. The long plates extend out of the slider 700, and two springs are provided on the long plates. A cylinder for connecting the springs is provided at the front end of the long plates.
[0030] It should be noted that such a design takes into account the spatial layout, making the installation more reasonable.
[0031] Furthermore, the front ends of the left clamp 300 and the right clamp 400 are processed with L-shaped notches.
[0032] Specifically, the two L-shaped slots are a left L-shaped slot and a right L-shaped slot, which together constitute a nut 800 accommodation space. The nut 800 to be processed falls into the accommodation space from the previous process, thereby further improving production efficiency.
[0033] Furthermore, the front end of the piston rod of the left cylinder 500 is connected to a left top head 501, the top of which is a ball head; the front end of the piston rod of the right cylinder 600 is connected to a right top head 601, the top of which is a ball head.
[0034] It should be noted that the ball head structure makes it more convenient to operate the control end.
[0035] The utility model is further described below in conjunction with the working principle.
[0036] 1. Slide the nut 800 smoothly into the slightly opened clamp. Figure 3 As shown;
[0037] 2. When the slider 700 moves forward, the left cylinder 500 and the right cylinder 600 simultaneously push the left clamp 300 and the right clamp 400 to lock the nut 800;
[0038] 3. The slider 700 carries the nut 800 into the tap for tapping;
[0039] 4. After the tapping is completed, the left cylinder 500 and the right cylinder 600 are simultaneously retracted to release the left clamp 300 and the right clamp 400;
[0040] 5. The slider 700 moves backward, and the tap locks the nut 800;
[0041] 6. During the backward movement of the slider 700, the left clamp 300 and the right clamp 400 are rotated outwardly by the nut 800 along the bottom of the opposite side of the nut 800 to open and pull out the nut 800. Figure 4 As shown;
[0042] 7. The slider 700 returns to the origin and the unloading plate surface, and the left clamp 300 and the right clamp 400 are slightly opened appropriately, waiting for the next nut 800 to be processed to enter.
[0043] The above embodiments are only used to help understand the method and core idea of the utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made to the utility model without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
