It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0017] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0018] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, including the closing clamp rotating handle pressing fixture.

[0019] Example 1: Combination Figures 1 to 4 As shown, the present invention provides a closing clamp rotating handle pressing fixture, including a handle pressing mechanism 100, a pressing angle adjustment mechanism 200 installed in the handle pressing mechanism 100, and a closing clamp 300 pre-installed in the pressing angle adjustment mechanism 200. The pressing angle adjustment mechanism 200 is used to perform a no-dead-angle pressing process on the closed clamp 300 after placement, thereby improving the pressing accuracy of the closed clamp 300. The handle pressing mechanism 100 is used to cooperate with the pressing angle adjustment mechanism 200 to perform a rapid pressing process on the closed clamp 300 after angle adjustment.

[0020] The handle pressing mechanism 100 includes a base 110, a slide rail is provided inside the base 110, and a slider 1501 is movably installed in the slide rail. An annular scale 140 is fixedly installed on the top of the base 110. A cover plate 1101 is installed on the outer end of the base 110. A pull rod 150 is movably installed in the cover plate 1101, and the inner end of the pull rod 150 is fixedly installed on the slider 1501. A bearing 1502 is installed inside the slider 1501, and a spring 160 is provided on the outside of the pull rod 150. The press-fit angle adjustment mechanism 200 includes a bottom mold pressing block 210, a top mold pressing block 220, and two positioning parts 250. The bottom mold pressing block 210 is installed in the bearing 1502. A suspension 2101 is fixedly installed on the bottom mold pressing block 2100. An auxiliary block 2102 is installed on the suspension 2101. A sealing plate 240 is snapped into the groove on the back of both the bottom mold pressing block 210 and the top mold pressing block 220. A limit rod 260 is fixedly installed in one of the bottom positioning parts 250, and the top positioning part 250 is movably installed on the limit rod 260. The suspension 2101 is composed of a crossbar and a bracket, and the top of the bracket is provided with a slot that bears pressure on the closing clamp 300 rod segment. The auxiliary block 2102 is welded together with a rectangular pad and a T-shaped column head, and the T-shaped column head is adapted to penetrate into the groove inside the annular scale 140. The closing clamp 300 is pre-installed in the groove on the top of the bottom mold pressure block 210.

[0021] In use, the bottom mold pressing block 210 is rotated in advance until the suspension 2101 rotates along the top of the annular scale 140. After the auxiliary block 2102 disengages from the inner groove of the annular scale 140, the auxiliary block 2102 is moved laterally. Then the bottom mold pressing block 210 and the top mold pressing block 220 are reset. Then the pull rod 150 is controlled to be stretched outward until the pull rod 150 drives the slider 1501 to slide outward along the inner slide of the bottom mold pressing block 210. The slider 1501 and the bearing 1502 will carry the bottom mold pressing block 210 to move laterally until the upper surface of the bottom mold pressing block 210 is in an undisturbed space. Next, place the closing clamp 300 horizontally and position the handle of the closing clamp 300 in the groove at the top of the bottom mold pressure block 210. Then release the pull rod 150. Under the lateral pressure of the spring 160, the bottom mold pressure block 210 will quickly return to its original position. Then rotate the bottom mold pressure block 210 until the auxiliary block 2102 passes through the groove inside the annular scale 140 again. According to the pressing requirements of different parts of the closing clamp 300 handle, the horizontally placed closing clamp 300 can be rotated by rotating the bottom mold pressure block 210 and the top mold pressure block 220 as a whole, which makes it easier for workers to observe the pressing status of the closing clamp 300 handle in real time.

[0022] Example 2: Combination Figure 2 and Figure 3 As shown, based on embodiment 1, a load-bearing frame 120 is fixedly installed on the top of the base 110, a top plate 1201 is fixedly installed on the top of the load-bearing frame 120, a cabinet 1202 is fixedly installed on the top of the top plate 1201, and a hydraulic component 130 is installed inside the cabinet 1202. The hydraulic sub-rod inside hydraulic component 130 is adapted to extend through to the outside of top plate 1201; Both ends of the cover plate 1101 are provided with elliptical slots, and two bolts 1102 are inserted into the elliptical slots. The two bolts 1102 are threaded into the base 110.

[0023] Preferably, two symmetrically distributed circular pads are fixedly installed at the bottom end of the hydraulic sub-rod inside the hydraulic component 130, and the two circular pads are located at the top and bottom of the pad plate 230 respectively. When the bottom mold pressure block 210 is rotated, the bottom mold pressure block 210 and the top mold pressure block 220, which are symmetrical in the vertical direction, will rotate freely around the hydraulic sub-rod as the center. The cover plate 1101 has a protruding end in the middle of its inner side that is adapted to be snapped into the inner slide of the base 110, which is used to enhance the stability of the tie rod 150 in lateral tension.

[0024] Example 3: Combination Figure 4 As shown, in the above embodiment, the press-fit angle adjustment mechanism 200 also includes a pad 230 movably installed at the bottom end of the hydraulic rod inside the hydraulic component 130, and four studs on the top of the top die pressing block 220 are adapted to penetrate into the pad 230. The sealing plate 240 has a through hole inside, and a pre-tightening bolt 2401 is inserted into the through hole. The two pre-tightening bolts 2401 are respectively threaded into the bottom mold pressure block 210 and the top mold pressure block 220.

[0025] Preferably, a slot adapted to the inner end post of the positioning member 250 is provided on one side of the sealing plate 240, and the inner end post of the positioning member 250 is coated with lubricating oil, while the four studs on the top of the top mold pressure block 220 fix the pad 230 by four nuts. The top of the limiting rod 260 is provided with a cylindrical anti-detachment end.

[0026] The working principle and usage process of this utility model are as follows: The bottom mold pressing block 210 and the top mold pressing block 220 are rotated as a whole. As the bottom rod segment of the bottom mold pressing block 210 rotates around the bearing 1502, the auxiliary block 2102 is disengaged from the groove inside the annular scale 140. Then, the auxiliary block 2102 is moved laterally toward the bottom mold pressing block 210. Then, the bottom mold pressing block 210 and the top mold pressing block 220 are reset, and the pull rod 150 is controlled to be stretched outward until the slider 1501 drives the bottom mold pressing block 210 to slide outward. When the pull rod 150 disengages from the inside of the annular scale 140 and approaches the cover plate 1101, the closing clamp 300 to be pressed is placed in the groove reserved on the top of the bottom mold pressing block 210. Then, the pull rod 150 is released. Under the elastic force of the spring 160, the slider 1501 will drive the bottom mold pressing block 210 to quickly return to the center position inside the annular scale 140. Then, the bottom mold pressing block 210 is controlled to rotate until the auxiliary block 2102 is inserted back into the groove inside the annular scale 140. Then, the hydraulic component 130 is operated. After the hydraulic rod inside the hydraulic component 130 extends outward, it pushes the pad 230 and the top mold block 220 down. Under the longitudinal guidance and constraint of the limit rod 260, the top mold block 220 cooperates with the bottom mold block 210 to quickly press the horizontally positioned closing clamp 300. In order to accurately press each part of the closing clamp 300 handle, the bottom mold block 210 and the top mold block 220 are rotated around the center of the inner side of the annular scale 140 to ensure that the components of the closing clamp 300 handle are accurately assembled.
