DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figures 1-6 As shown, a base casting for a press machine includes a base 1. Four rectangularly distributed fixing holes 2 are opened on the upper side of the base 1 near the edge. Four rectangularly distributed fixing sleeves 3 are fixedly connected to the inner lower surface of the base 1 near the edge. A bottom platform 4 is fixedly connected to the middle of the inner lower surface of the base 1. A fixing mechanism 5 is fixedly connected to the inner side of the base 1. A closing mechanism 6 is rotatably connected to the inner side of the upper wall of the base 1.

[0029] The fixing mechanism 5 includes two clamping seats 51, and four first limiting rods 52 distributed in a front and rear rectangular manner are movably sleeved on the front and rear sides of the clamping seats 51. The two ends of the first limiting rods 52 are fixedly connected to the left and right sides of the inner side of the base 1. The front and rear sides of the inner side of the base 1 are rotatably connected to two screw rods 53 distributed in the front and rear. The outer sides of the two screw rods 53 are threadedly connected to two limiting plates 54 symmetrically distributed on the left and right sides near the left and right ends. The upper and lower sides of the limiting plates 54 are movably sleeved on the outer sides of the first limiting rods 52. The outer sides of the four first limiting rods 52 are movably sleeved with two first springs 55 distributed on the left and right sides, and the first springs 55 are located between the clamping seat 51 and the limiting plates 54.

[0030] The closing mechanism 6 includes two baffles 61 , the outer middle portion of the baffle 61 is rotatably connected to the left and right sides of the inner upper wall of the base 1 , and the inner sides of the two baffles 61 are movably sleeved with an inserting plate 62 , and the inserting plate 62 is located on the inner sides of the two baffles 61 .

[0031] It should be noted that, by rotating the screw 53, which is a bidirectional screw, the two limit plates 54 are threadedly connected with threads in different directions, so that the left and right limit plates 54 on the same side are synchronously moved closer to or away from each other, causing the compression amount of the first spring 55 to change, and the thrust of the first spring 55 on the base 51 to change, and the insert plate 62 can slide on the inner side of the baffle 61. When the insert plate 62 is simultaneously movably inserted into the inner sides of the two baffles 61, the insert plate 62 fixes the baffle 61 so that the baffle 61 cannot rotate.

[0032] like Figure 3 、 Figure 4 As shown, a worm 56 is rotatably connected to the middle of the inner lower surface of the base 1, and a worm wheel 57 is meshedly connected to the upper side of the worm 56. The left ends of the two screws 53 and the front and rear sides of the worm wheel 57 are fixedly connected to bevel gears 58, and the two adjacent bevel gears 58 are meshedly connected together. A transmission assembly 59 is rotatably connected to the inner side of the base 1 near the right side, and a second gear 510 is fixedly connected to the outer side of the worm 56 near the right end.

[0033] It should be noted that the transmission assembly 59 drives the worm 56 to rotate, and when the worm 56 rotates, it drives the worm wheel 57 to rotate, and when the worm wheel 57 rotates, it drives the bevel gear 58 to rotate, and when the bevel gear 58 rotates, it drives the screw 53 to rotate. There is a self-locking effect between the worm 56 and the worm wheel 57, so that the worm 56 can drive the worm wheel 57 to rotate, but the worm wheel 57 cannot drive in the opposite direction, so that when the worm 56 is fixed, the screw 53 is also in a fixed state.

[0034] like Figure 5 As shown, the transmission assembly 59 includes a sleeve 591, the right side of the sleeve 591 is rotatably connected to the right side of the inner vertical side of the base 1, the left end of the sleeve 591 is fixedly connected to the first gear 592, the lower side of the first gear 592 is meshed and connected with the upper side of the second gear 510, and the inner side of the sleeve 591 is movably sleeved with a transmission rod 593.

[0035] It should be noted that rotating the transmission rod 593 causes the transmission rod 593 to drive the sleeve 591 to rotate, and when the sleeve 591 rotates, it drives the first gear 592 to rotate. When the first gear 592 rotates, it drives the second gear 510 to rotate, causing the second gear 510 to drive the worm 56 to rotate.

[0036] like Figure 5As shown, the outer side of the convex ring near the right end of the transmission rod 593 is rotatably connected to the outer side of the fixed ring 595, and the fixed ring 595 is located on the outer side of the base 1, and the right middle part of the base 1 is fixedly connected with a clamping sleeve 594, and the inner side of the clamping sleeve 594 is provided with a plurality of annularly distributed first fixed grooves 596, and the inner side of the clamping sleeve 594 is provided with a plurality of annularly distributed second fixed grooves 597, and the first fixed grooves 596 and the second fixed grooves 597 are arranged alternately, and the outer side convex block of the fixed ring 595 is movably sleeved on the inner side of the first fixed groove 596.

[0037] It should be noted that the length of the first fixed groove 596 is shorter than that of the second fixed groove 597, and the first fixed groove 596 and the second fixed groove 597 are both connected to the left side of the sleeve 594, so that when the outer protrusions of the fixing ring 595 are movably connected to the inner sides of the first fixed groove 596 and the second fixed groove 597, respectively, the transmission rod 593 has two left and right position states.

[0038] like Figure 5 As shown, a plurality of annularly distributed slots 598 are provided on the left side of the convex ring near the right side of the transmission rod 593.

[0039] It should be noted that when the transmission rod 593 is in a position on the left side, the right side protrusion on the inner side of the sleeve 594 is movably inserted into the inner side of the slot 598, causing the sleeve 594 to restrict the transmission rod 593, so that the transmission rod 593 cannot rotate.

[0040] like Figure 5 As shown, the left end of the transmission rod 593 is fixedly connected to the second limiting rod 599, and the left position of the inner middle part of the sleeve 591 is fixedly connected to the top plate 5911. The outer side of the second limiting rod 599 is movably sleeved on the inner side of the top plate 5911, and the outer side of the second limiting rod 599 is movably sleeved with the second spring 5910, and the second spring 5910 is located on the left side of the top plate 5911.

[0041] It should be noted that a circular plate is provided at the left end of the second limiting rod 599 , and the second spring 5910 pushes the circular plate so that the transmission rod 593 can automatically reset after being pulled to the left and released.

[0042] like Figure 6 As shown, the sides of the two inserting plates 62 away from each other are fixedly connected to the third spring 64, and the sides of the two baffles 61 away from each other and the sides of the two inserting plates 62 close to each other are fixedly connected to the hanging ring 63.

[0043] It should be noted that the third spring 64 pushes the inserting plate 62 so that the inserting plate 62 can be automatically inserted into the inner sides of the two baffles 61 .

[0044] The working principle of the present invention is as follows: First, the screw 53 is rotated. The screw 53 is a bidirectional screw. The two limit plates 54 are respectively threadedly connected with threads in different directions, so that the left and right limit plates 54 on the same side are synchronously moved closer to or away from each other, causing the compression amount of the first spring 55 to change, so that the thrust of the first spring 55 on the base 51 changes, and the transmission assembly 59 drives the worm 56 to rotate. When the worm 56 rotates, it drives the worm wheel 57 to rotate. When the worm wheel 57 rotates, it drives the bevel gear 58 to rotate. When the bevel gear 58 rotates, it drives the screw 53 to rotate. The worm 56 and the worm 57 rotate. There is a self-locking effect between the wheels 57, which causes the worm 56 to drive the worm wheel 57 to rotate, but the worm wheel 57 cannot drive in the opposite direction. As a result, when the worm 56 is fixed, the screw 53 is also in a fixed state, and the worm 56 is driven to rotate by the transmission component 59, so that the left and right limit plates 54 on the same side move in opposite directions in the left and right directions, so that the centers of the two clamping seats 51 are always in the middle of the base 1. At the same time, relying on the first spring 55, the clamping force of the clamping seat 51 can be controlled by the compression amount of the first spring 55, which is convenient to adjust and simple to operate. The transmission rod 593 is driven, causing the transmission rod 593 to drive the sleeve 591 to rotate. When the sleeve 591 rotates, it drives the first gear 592 to rotate. When the first gear 592 rotates, it drives the second gear 510 to rotate, causing the second gear 510 to drive the worm 56 to rotate. The first fixed groove 596 is shorter than the second fixed groove 597. The first fixed groove 596 and the second fixed groove 597 are both connected to the left side of the ferrule 594. When the outer protrusions of the fixing ring 595 are movably sleeved on the inner sides of the first fixed groove 596 and the second fixed groove 597, the transmission rod 593 is rotated. There are two position states, left and right. When the transmission rod 593 is in the position state on the left, the right side protrusion on the inner side of the sleeve 594 is movably sleeved into the inner side of the slot 598, causing the sleeve 594 to restrict the transmission rod 593, so that the transmission rod 593 cannot rotate. The inner side protrusion of the sleeve 594 is movably sleeved into the slot 598 or detached from it, so that the transmission rod 593 is controlled to be able to rotate, and then the entire fixing mechanism 5 can be restricted in rotation, thereby preventing the first gear 592 from rotating on its own due to external vibration, which causes the clamping force of the fixing mechanism 5 to change.

[0045] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
