Description

Technical Field

[0001] The present invention relates to the field of construction machinery, and particularly to a 90-degree grooved wheel turnover machine. Background Art

[0002] In the manufacturing of construction machinery, the production efficiency of the automated production line determines a great deal of economic benefits. In many production lines, the processing requirement is to turn over the workpieces to facilitate the installation of components. In order to ensure the installation quality of the installed components, it is necessary to vigorously develop the corresponding installation equipment that can improve the production efficiency and quality. During the installation and machining of components, some workpieces need to be turned over by 90 degrees. Generally, the method is to use a crane to lift, move after raising one end and then lower it to turn over the workpiece. For large structural parts, this operation is quite dangerous and is also limited by the lifting height of the crane. Another method is to lift it onto a turnover machine for turning over, but this method has poor operation safety due to the large rotation radius of the workpiece and the high clamping position. There is also a method of turning over like turning a book. Although the turning-over position is low when turning over like a book, the occupied space is very large. If the workpiece is first clamped at a low position, then raised to a certain height for turning over, and then lowered for disassembly after completion, the production efficiency is low and the equipment manufacturing cost is high. Through statistics, it is found that the potential production safety hazards of turning over large structural parts are widespread in the field of construction machinery manufacturing. In order to solve the technical problems existing in the prior art, the present invention designs a part turnover mechanism, which is applicable to the turnover of medium and small workpieces and is safe, reliable and simple to operate during the use and operation process. Summary of the Invention

[0003] The purpose of the present invention is to provide a 90-degree grooved wheel turnover machine to solve the disadvantages of the existing turnover machine equipment in the above-mentioned background art, such as high requirements for the working environment, high cost, large impact during startup and stop, frequent damage to machine parts and inaccurate positioning. A 90-degree grooved wheel turnover machine with a simple structure, accurate positioning, and smooth movement during startup and stop is designed. It can not only work accurately and stably in various working environments, but also has a low cost and less damage to machine parts.

[0004] To achieve the above purpose, the present invention adopts the following scheme: The present invention provides a 90-degree grooved wheel turnover machine, including a frame, a turnover system, and a transmission system. The frame includes a motor bench and a turnover machine bench. The motor bench is fixedly connected to the motor to support and fix the motor. The turnover machine bench is fixedly connected to the turnover system to support and fix the turnover mechanism. The motor cooperates with a reduction device to reduce the speed and transmit the power to the intermittent transmission mechanism. The horizontal clamping movement device clamps the workpiece, and the intermittent transmission mechanism and the horizontal clamping movement device in the turnover system cooperate to turn the workpiece by 90 degrees.

[0005] Further, in the frame, there are a motor bench and a tilter bench. In the motor bench, the motor plate welder is on the bench, the motor is installed on the motor plate by bolts, the reducer plate is also welded on the bench, and the reducer is installed on the reducer plate by bolts.

The left and right ends of the sprocket wheel shaft are respectively arranged in the left and right tapered roller bearings B, and the left and right tapered roller bearings B are respectively installed in the left and right bearing holes B in the intermittent drive mechanism housing. The right end of the sprocket wheel shaft is positioned and sealed by the bearing end cover B, and the left end is positioned and sealed by the through cover B. The right end of the sprocket wheel shaft is connected to the tilting shaft through the LX2 coupling C to transmit the intermittent motion to the jaws. In the horizontal clamping device, the right end of the right tilting shaft is arranged in a tapered roller bearing, and the tapered roller bearing is arranged in the bearing hole C on the right rear clamping seat.

[0027] As Figure 1 — Figure 5 shown, the 90-degree Geneva wheel rotary machine described in the present invention basically comprises a frame, a rotary system and a transmission system

[0028] Furthermore, as Figure 3In the schematic diagram of the shown frame structure, it includes the motor bench 1-1 and the tilter bench 1-2.

[0029] Further, as Figure 4 Figure 5As shown, in the flipping system 2, there is an intermittent drive mechanism 2-1 and a horizontal clamping device 2-2. In the intermittent drive mechanism 2-1, the indexing shaft 2-1-1 is connected to the power output shaft of the ZQA type reducer 3-3 in the drive system 3 through the LX2 coupling B3-4. The indexing shaft 2-1-1 is the power input shaft of the flipping system 2. Both ends of the indexing shaft 2-1-1 are arranged in the left and right two tapered roller bearings 2-1-2A. The left and right two tapered roller bearings A2-1-2 are installed in the left and right two bearing holes A2-1-9 of the intermittent drive mechanism housing 2-1-3. The outer end of the right tapered roller bearing A2-1-2 is positioned and sealed with a through cover A2-1-4, and the outer end of the left tapered roller bearing A2-1-2 is positioned and sealed with a bearing end cover A2-1-5. The indexing plate 2-1-6 and the indexing shaft 2-1-1 are an integral part. The indexing plate 2-1-6 cooperates with the Geneva wheel 2-1-7 and drives the latter. The Geneva wheel 2-1-7 and the Geneva wheel shaft 2-1-8 are an integral part. The left and right ends of the Geneva wheel shaft 2-1-8 are respectively arranged in the left and right two tapered roller bearings B2-1-10. The left and right two tapered roller bearings B2-1-10 are respectively installed in the left and right two bearing holes B2-1-11 of the intermittent drive mechanism housing 2-1-3. The right end of the Geneva wheel shaft 2-1-8 is positioned and sealed with a bearing end cover B2-1-12, and the left end is positioned and sealed with a through cover B2-1-13. The right end of the Geneva wheel shaft 2-1-8 is connected to the flipping shaft 2-2-1 through the LX2 coupling C2-1-14 to transfer the intermittent motion to the jaw 2-2-2. In the horizontal clamping device 2-2, the right end of the right flipping shaft 2-2-1 is arranged in the tapered roller bearing 2-2-3. The tapered roller bearing 2-2-3 is arranged in the bearing hole C2-2-5 on the right rear clamping seat 2-2-4. The right end of the bearing 2-2-3 is sealed with a cover 2-2-6. The bushing 2-2-7 is wrapped around the periphery of the flipping shaft 2-2-1. The left end of the right flipping shaft 2-2-1 is fixedly connected to the right jaw 2-2-8 as a whole. The left jaw 2-2-9 is fixedly connected to the left flipping shaft 2-2-10 as a whole. The left flipping shaft 2-2-10 is arranged in the left rear clamping seat 2-2-11 in the same way. The left rear clamping seat 2-2-11 is connected to the cylinder fixing seat 2-2-12 through bolts. The cylinder fixing seat 2-2-12 is connected to the cylinder 2-2-13 as a whole. The right rear clamping seat 2-2-4 is also connected to a cylinder 2-2-14. The structure of the cylinder 2-2-14 is exactly the same as that of the cylinder 2-2-13. The cylinders 2-2-13 and 2-2-14 provide the horizontal clamping force for the right jaw 2-2-8 and the left jaw 2-2-9. The left rear clamping seat 2-2-11 is also fixedly connected to the rack 2-2-15. The rack 2-2-15 meshes with the gear 2-2-16 to guide the horizontal clamping movement of the jaw 2-2-2.Meanwhile, a synchronous shaft 2-2-17 is arranged between the right jaw 2-2-8 and the left jaw 2-2-9. The synchronous shaft 2-2-17 transmits the intermittent motion generated by the intermittent transmission mechanism 2-1 from the right jaw 2-2-8 to the left jaw 2-2-9 and synchronizes the motions of the two jaws.

[0030] Further, as Figure 2 shown, in the transmission system 3, the electric motor 3-1 provides power, and its power output shaft A 3-5 is connected to the power input shaft 3-6 of the ZQA type reducer 3-3 through the LX2 coupling A 3-2. The ZQA type reducer 3-3 is a single-stage reducer, and its power output shaft B 3-7 is connected to the dial shaft 2-1-1 through the LX2 coupling B 3-4.

[0031] A 90-degree grooved wheel turnover machine has the following working principle and process:

[0032] After the three-phase asynchronous motor 3-1 starts, the rotational speed output by its power output shaft 3-5 is relatively high. The power output shaft 3-5 is connected to the power input shaft 3-6 of the ZQA type reducer 3-3 through the LX2 coupling A 3-2. This relatively high rotational speed is transmitted to the power input shaft 3-6 of the ZQA type reducer 3-3. This power input shaft 3-6 is the high-speed shaft of the ZQA type reducer 3-3. After a single-stage reduction by the reducer, the power output shaft 3-7 of the ZQA type reducer 3-3 will output a relatively low rotational speed. The power output shaft B 3-7 of the ZQA type reducer 3-3 is connected to the dial shaft 2-1-1 through the LX2 coupling B 3-4, transmitting this relatively low rotational speed to the dial shaft 2-1-1, thereby driving the dial 2-1-15 to rotate. The dial 2-1-6 cooperates with the grooved wheel 2-1-7. Due to the structural characteristics of the grooved wheel 2-1-7, the continuous rotary motion of the dial 2-1-6 can be converted into the intermittent rotary motion of the grooved wheel 2-1-7, and each intermittent grooved wheel 2-1-7 rotates 90 degrees. The grooved wheel 2-1-7 and the grooved wheel shaft 2-1-8 are an integral whole, so the grooved wheel shaft 2-1-8 also makes intermittent rotary motion. The grooved wheel shaft 2-1-8 and the turnover shaft 2-2-1 are connected through the LX2 coupling C 2-1-14, transmitting the intermittent motion to the turnover shaft 2-2-1, thereby driving the jaw 2-2-2 to make intermittent rotary motion. During each motion interval, the cylinder A 2-2-13 and the cylinder 2-2-14B work, driving the left jaw 2-2-9 to move horizontally to the right. The left jaw 2-2-9 is the mobile end, and the right jaw 2-2-8 is the fixed end. At the same time, in order to ensure the accuracy of the horizontal motion, the meshing structure of the rack 2-2-15 and the gear 2-2-16 guides the horizontal motion of the left jaw 2-2-9 to the right. After the left jaw 2-2-9 moves horizontally to the right and clamps the workpiece, the jaw 2-2-2 starts to make intermittent rotation, thereby achieving the purpose of turning the workpiece by 90 degrees.
