Description

Technical Field

[0001] This utility model relates to the field of six-sided top press technology, specifically to the synchronous lifting mechanism of the movable crossbeam of a six-sided top press. Background Technology

[0002] Six-sided presses are core equipment in the synthesis of superhard materials such as diamond and cubic boron nitride. In the diamond production field, due to the need for mass production, a large number of six-sided presses are required for simultaneous operation.

[0003] Currently, during the operation of a six-sided top press, in order to ensure worker safety, the six-sided top press needs to be installed inside an explosion-proof frame. The six-sided fixed press is installed on a movable crossbeam, and mostly adopts a single press independent crossbeam or asymmetrical drive mechanism, without an integrated lifting design. It is necessary to control the crossbeam of each press to retract into the explosion-proof frame, process it, and then push it out one by one. The entire lifting process is time-consuming, which seriously restricts the continuity of mass production and results in low overall equipment utilization. Therefore, we need to propose a synchronous lifting mechanism for the movable crossbeam of the six-sided top press. Utility Model Content

[0004] The purpose of this utility model is to provide a synchronous lifting mechanism for the movable crossbeam of a six-sided top press. By centrally installing several sets of six-sided top presses on a lifting base, and then using four sets of bidirectional motors to drive the moving components to move the lifting base, the lifting base synchronously drives several sets of six-sided top presses to lift. This solution realizes an integrated lifting design for the six-sided top press, shortens the lifting time during operation, improves the continuity of mass production of the six-sided top press, and increases the overall utilization rate of the six-sided top press, thereby solving the problems mentioned in the background art.

A threaded rod is inserted and fixed at the center of the second gear. The bottom end of the threaded rod is rotatably connected to the inner cavity of the mounting frame via a bearing. A support seat is provided at the top end of the threaded rod. A support column is welded and fixed to the top end of the support seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model provides a synchronous lifting mechanism for the movable crossbeam of a six-sided top press. Through the cooperation of a lifting seat and several sets of mounting seats, several sets of six-sided top presses can be integrated and installed on the lifting seat simultaneously. By setting up bidirectional motors, the bidirectional motors start synchronously to drive the rotating rod to rotate. The rotating rod starts the moving seat to drive the lifting seat to move, so that the several sets of six-sided top presses on the lifting seat can be lifted and lowered synchronously. By setting up four sets of bidirectional motors, the four sets of bidirectional motors drive the rotating rod to rotate synchronously, which improves the stability of the lifting seat when moving. The above solution realizes the integrated lifting design of the six-sided top press, shortens the lifting time during the operation of the six-sided top press, improves the continuity of mass production of the six-sided top press, and improves the overall utilization rate of the six-sided top press.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a synchronous lifting mechanism for the movable crossbeam of a six-sided top press, including a mounting frame 1. The top of the mounting frame 1 is provided with a lifting seat 2 for driving several sets of six-sided top presses to lift. Several sets of mounting seats 3 for mounting the six-sided top presses are evenly distributed around the top of the lifting seat 2. An adjustment mechanism for adjusting the height of the lifting seat 2 is installed in the inner cavity of the mounting frame 1. The adjustment mechanism includes a bidirectional motor 4. The bidirectional motor 4 is fixed to the inner side wall of the mounting frame 1 by mounting plate bolts. The output shaft of the bidirectional motor 4 is connected to a rotating rod 5 through a reducer. The other end of the rotating rod 5 is connected to a moving component for driving the lifting seat 2 to move. There are four sets of bidirectional motors 4, and the four sets of bidirectional motors 4 are symmetrically distributed around the inner cavity of the mounting frame 1.

[0022] During processing, four sets of bidirectional motors 4 are started simultaneously. The bidirectional motors 4 drive the rotating rod 5 through the output shaft and reducer to rotate. The rotating rod 5 drives the moving component to move, which in turn drives the lifting seat 2 to move. The lifting seat 2 drives several sets of six-sided top presses to move synchronously through the mounting base 3, realizing the lifting operation of the six-sided top press. When the bidirectional motors 4 rotate forward, the six-sided top press rises; when the bidirectional motors 4 rotate in reverse, the six-sided top press descends. The above scheme realizes the integrated lifting design of the six-sided top press, shortens the lifting time during the operation of the six-sided top press, improves the continuity of mass production of the six-sided top press, and improves the overall utilization rate of the six-sided top press.

[0023] This embodiment also includes a bidirectional motor 4 connected to a power supply device via a power cord. The signal line of the bidirectional motor 4 is connected to a PLC controller. An encoder is also installed on the bidirectional motor 4. The operator adjusts the speed of the four bidirectional motors 4 to be equal through the encoder. The model of the bidirectional motor 4 is YVP132M-4.

[0024] The moving component includes gear 6, which is keyed to the surface of the rotating rod 5. Gear 7 is meshed with the surface of gear 6. A threaded rod 8 is inserted and fixed at the center of gear 7. The bottom end of the threaded rod 8 is rotatably connected to the inner cavity of the mounting frame 1 through a bearing. A support seat 9 is provided at the top end of the threaded rod 8. A support column 10 is welded and fixed to the top end of the support seat 9. The top end of the support column 10 is welded and fixed to the bottom end of the lifting seat 2. The rotating rod 5 drives gear 6 to rotate. Gear 6 drives gear 7 to rotate through its teeth. Gear 7 drives the threaded rod 8 to rotate. The threaded rod 8 drives the support seat 9 to move, so that the support seat 9 drives the lifting seat 2 to move through the support column 10, thereby realizing the lifting operation of the lifting seat 2. Both gear 6 and gear 7 are bevel gears.

[0025] A threaded seat 11 is integrally formed at the center of the support base 9. The inner cavity of the threaded seat 11 is threadedly connected to the surface of the threaded rod 8. When the threaded rod 8 rotates, it drives the support base 9 to move by engaging with the threaded seat 11, thereby realizing the lifting and lowering operation of the support base 9.

[0026] The threaded seat 11 has movable holes around its perimeter. A support rod 12 is slidably connected to the inner cavity of the movable hole. The bottom end of the support rod 12 is welded and fixed to the bottom end of the inner cavity of the mounting frame 1. A limit block is bolted to the top end of the support rod 12. The support rod 12 can support the perimeter of the support seat 9, providing guidance for the movement of the support seat 9 and improving the stability of the support seat 9 when it moves.

[0027] The inner wall of the mounting frame 1 is provided with a slide groove 13. The inner cavity of the slide groove 13 is provided with a slider 14 that is compatible with the slide groove 13. The slider 14 is bolted to the surface of the lifting seat 2. The slide groove 13 and the slider 14 can support the lifting seat 2 and provide guidance for the movement of the lifting seat 2, preventing the lifting seat 2 from rotating when it moves and improving the stability of the lifting seat 2 when it moves.

[0028] The side of the slider 14 away from the lifting seat 2 has a slot. The inner cavity of the slot of the slider 14 is rotatably connected to a roller 15 to reduce the friction generated by sliding through a bearing. With the setting of the roller 15, when the slider 14 moves, it drives the roller 15 to roll in the slide groove 13. The roller 15 reduces the friction between the slider 14 and the slide groove 13, and at the same time supports the lifting seat 2, reducing the wear between the slider 14 and the slide groove 13.

[0029] Several sets of sliders 14 are provided, and the several sets of sliders 14 are symmetrically distributed around the lifting seat 2. By setting the number of sliders 14, the lifting seat 2 can be supported around its perimeter, further improving the stability of the lifting seat 2 when it moves.

[0030] In practical use: During processing, four sets of bidirectional motors 4 are started simultaneously. The bidirectional motors 4 drive the rotating rod 5 through the output shaft and reducer to rotate. The rotating rod 5 drives the gear 6 to rotate. The gear 6 drives the gear 7 through its teeth to rotate. The gear 7 drives the threaded rod 8 to rotate. The threaded rod 8 drives the support seat 9 to move through the threaded connection with the threaded seat 11. The support seat 9 lifts the lifting seat 2 through the support column 10 to move. This causes several sets of six-sided top presses on the lifting seat 2 to move. When the bidirectional motors 4 rotate forward, the six-sided top presses rise. When the bidirectional motors 4 rotate in reverse, the six-sided top presses fall. The above scheme realizes the integrated lifting design of the six-sided top press, shortens the lifting time of the six-sided top press during operation, improves the continuity of mass production of the six-sided top press, and improves the overall utilization rate of the six-sided top press.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
