This utility model improves machine tool assembly efficiency and enhances modularity.

[0004] During the long-term operation of the rotary table and punch press, rust will appear on the surface of the device, and the device will also age. The device in the above application does not have a self-lubricating effect, which will affect the subsequent use of the device and thus lead to low working efficiency.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing punch press turntable. Utility Model Content

[0006] The purpose of this invention is to provide a self-lubricating punch press turntable to solve the problem mentioned in the background art that the lack of self-lubrication affects the subsequent use of the device and leads to low working efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a self-lubricating punch press turntable, comprising an equipment box, a bracket fixedly connected to the lower surface of the equipment box, a work plate bolted to the upper surface of the equipment box, and a base plate fixedly connected to the upper surface of the equipment box;

[0008] A self-lubricating punch press turntable also includes:

[0009] A robotic arm, which is bolted to the upper surface of the work plate, and an electric telescopic rod is fixedly connected to the surface of the work plate;

[0010] The motor is fixedly connected to the inner wall of the base plate, and the output end of the motor is fixedly connected to a first bevel gear. The base plate is rotatably provided with a connecting shaft, and the end of the connecting shaft is fixedly connected to an auxiliary plate.

[0011] A fixing block is fixedly disposed on the upper surface of the auxiliary plate;

[0012] A baffle is slidably disposed inside the base plate, and a first magnet is embedded in the inner wall of the end of the baffle, and a groove is provided inside the base plate.

[0013] The upper connecting block is fixedly installed on the upper surface of the base plate.

[0014] Preferably, a connecting rod is fixedly connected to the lower surface of the connecting shaft, and a second bevel gear that meshes with the first bevel gear is fixedly connected to the lower surface of the connecting rod, and ball bearings are rotatably provided inside the connecting shaft.

[0015] Preferably, the ball bearing is rotatably disposed inside the base plate, and a conveying channel is provided inside the base plate. A second magnet is fixedly connected to the lower surface of the auxiliary plate, and a limit block is fixedly connected to the surface of the connecting shaft.

[0016] Preferably, a slider is fixedly connected to the side of the baffle, and a connecting spring that plays an elastic reset role is fixedly connected to the upper surface of the slider, and the other side of the connecting spring is fixedly connected to the inner wall of the base plate.

[0017] Preferably, the magnetic poles on the lower surface of the second magnet are opposite to the magnetic poles on the upper surface of the first magnet, the conveying channel is inclined, and the conveying channels are symmetrically distributed about the center of the base plate.

[0018] Preferably, the upper connecting block is provided with a crossbar that rotates inside, and a pressure plate is fixedly connected to the surface of the crossbar.

[0019] Preferably, a torsion spring that provides elastic reset is fixedly connected to the surface of the crossbar, and the other side of the torsion spring is fixedly connected to the inner wall of the upper connecting block.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the self-lubricating punch press turntable adopts a novel structural design, the specific details of which are as follows:

[0021] (1) The self-lubricating punch press turntable has a fixed block for placing workpieces. When working, the motor is started, and the motor drives the connecting rod and connecting shaft to rotate through the first bevel gear and the second bevel gear. When the connecting shaft rotates, it drives the auxiliary plate to rotate synchronously. The workpieces on the fixed block on the upper surface of the auxiliary plate also move and are picked up by the robotic arm. The workflow is quick and convenient.

[0022] Furthermore, during the rotation of the auxiliary plate, the second magnet will approach the first magnet. When the second magnet moves to the upper surface of the first magnet, the baffle rises under the action of mutual magnetic attraction. At this time, the lubricating oil enters the limiting block and the connecting shaft through the conveyor channel, which facilitates the lubrication of the connecting shaft.

[0023] (2) When the baffle rises under the action of mutual magnetic attraction, the slider slides inside the groove. At this time, the slider will squeeze the connecting spring. When the auxiliary plate continues to rotate and the second magnet moves away from the first magnet, the baffle falls under its own weight and the action of the connecting spring. The baffle blocks the conveyor again, so that the lubricating oil no longer flows.

[0024] Furthermore, when lubricating oil needs to be added, the pressure plate can be pulled upwards. At this time, the pressure plate rotates around the crossbar, opening the pressure plate so that the operator can add lubricating oil into the conveyor, making the use of lubricating oil convenient.

[0025] Furthermore, when the crossbar rotates, it stretches the torsion spring. Then, after adding lubricating oil, the pressure plate is released. At this time, the pressure plate rotates under the action of the crossbar and the torsion spring, blocking the conveyor channel and preventing impurities from entering the bottom plate.

[0034] 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.

[0035] Please see Figures 1-7 This utility model provides the following technical solution: a self-lubricating punch press turntable:

[0036] Example 1: The auxiliary board 11 is made to work normally by the motor 6, such as... Figures 1-3 As shown:

[0037] The equipment includes a housing 1, a bracket is fixedly connected to the lower surface of the housing 1, a working plate 2 is bolted to the upper surface of the housing 1, and a base plate 5 is fixedly connected to the upper surface of the housing 1.

[0038] A self-lubricating punch press turntable also includes:

[0039] The robotic arm 3 is bolted to the upper surface of the work plate 2, and an electric telescopic rod 4 and a motor 6 are fixedly connected to the surface of the work plate 2. The motor 6 is fixedly connected to the inner wall of the base plate 5, and the output end of the motor 6 is fixedly connected to the first bevel gear 7. The base plate 5 is rotatably provided with a connecting shaft 8, and the end of the connecting shaft 8 is fixedly connected to an auxiliary plate 11.

[0040] A fixing block 12 is fixedly installed on the upper surface of the auxiliary plate 11. A baffle 17 is slidably installed inside the base plate 5, and a first magnet 18 is embedded in the inner wall of the end of the baffle 17. A sliding groove 20 is opened inside the base plate 5. An upper connecting block 16 is fixedly installed on the upper surface of the base plate 5.

[0041] A connecting rod 9 is fixedly connected to the lower surface of the connecting shaft 8, and a second bevel gear 10 that meshes with the first bevel gear 7 is fixedly connected to the lower surface of the connecting rod 9. A ball bearing 13 is rotatably provided inside the connecting shaft 8.

[0042] The ball bearing 13 is rotatably disposed inside the base plate 5, and the base plate 5 has a conveyor channel 15. The lower surface of the auxiliary plate 11 is fixedly connected to the second magnet 25, and the surface of the connecting shaft 8 is fixedly connected to the limit block 14.

[0043] During operation, the motor 6 is started, and the motor 6 drives the connecting rod 9 and the connecting shaft 8 to rotate through the first bevel gear 7 and the second bevel gear 10. When the connecting shaft 8 rotates, it drives the auxiliary plate 11 to rotate synchronously. The workpiece on the fixed block 12 on the upper surface of the auxiliary plate 11 also moves and is picked up by the robotic arm 3. The workflow is quick and convenient. When the connecting shaft 8 rotates, it drives the ball bearing 13 and the limiting block 14 to rotate synchronously. The limiting block 14 and the ball bearing 13 prevent the connecting shaft 8 from moving in the vertical direction.

[0044] Example 2: Unlike Example 1, the conveyor channel 15 allows lubricating oil to enter the connecting shaft 8 and the limiting block 14, facilitating lubrication. Figure 4 and Figure 5 As shown:

[0045] A slider 19 is fixedly connected to the side of the baffle 17, and a connecting spring 21 that plays an elastic reset role is fixedly connected to the upper surface of the slider 19. The other side of the connecting spring 21 is fixedly connected to the inner wall of the base plate 5. The magnetic poles on the lower surface of the second magnet 25 are opposite to the magnetic poles on the upper surface of the first magnet 18. The conveying channel 15 is inclined and symmetrically distributed about the center of the base plate 5.

[0046] During the rotation of the auxiliary plate 11, the second magnet 25 will approach the first magnet 18. When the second magnet 25 moves to the upper surface of the first magnet 18, the baffle 17 rises under the action of mutual magnetic attraction. At this time, the lubricating oil enters the limiting block 14 and the connecting shaft 8 through the conveying channel 15, which facilitates the lubrication of the connecting shaft 8. When the baffle 17 rises under the action of mutual magnetic attraction, the slider 19 slides inside the slide groove 20. At this time, the slider 19 will squeeze the connecting spring 21. When the auxiliary plate 11 continues to rotate and the second magnet 25 moves away from the first magnet 18, the baffle 17 falls under the action of its own weight and the connecting spring 21. The baffle 17 blocks the conveying channel 15 again, so that the lubricating oil no longer flows. The above process is repeated, and the device has the function of intermittent self-lubrication.

[0047] Example 3: Unlike Example 2, the pressure plate 23 can cover the conveyor channel 15, preventing impurities from entering the interior of the conveyor channel 15. Figure 6 and Figure 7 As shown:

[0048] The upper connecting block 16 has a crossbar 22 rotatably mounted inside, and a pressure plate 23 is fixedly connected to the surface of the crossbar 22. A torsion spring 24 that plays an elastic reset role is fixedly connected to the surface of the crossbar 22, and the other side of the torsion spring 24 is fixedly connected to the inner wall of the upper connecting block 16.

[0049] When lubricating oil needs to be added, the pressure plate 23 can be pulled upwards. At this time, the pressure plate 23 rotates around the crossbar 22, opening the pressure plate 23, allowing the operator to add lubricating oil into the conveyor 15. When the crossbar 22 rotates, it stretches the torsion spring 24. After adding lubricating oil, the pressure plate 23 is released. At this time, the pressure plate 23 rotates back under the action of the crossbar 22 and the torsion spring 24, blocking the conveyor 15 again and preventing impurities from entering the bottom plate 5.

[0050] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0051] 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.
