Description

Technical Field

[0001] This utility model relates to the field of spinning machine technology, and specifically to a spinning wheel adjustment device for a spinning machine. Background Technology

[0002] Spinning presses are a type of production machinery used for pressing and shaping. Modern spinning presses use spinning wheels to squeeze parts, causing them to bend and press into shape. Ordinary spinning can form thin-walled rotating parts such as spheres, ellipsoids, curved generatrices, cups, and cones.

[0003] A search revealed that the Chinese patent "A Spinning Machine's Spinning Wheel Device" (authorization announcement number CN212494772U) includes a spinning machine. The spinning machine has two spinning wheels, detachably connected inside. An adjusting guide rail is installed inside the spinning machine, connecting the spinning wheels to the guide rail. An inner groove is located in the center of the top plate, and a telescopic motor is fixedly connected inside the groove. The output end of the telescopic motor extends out of the inner groove and is rotatably connected to a clamping plate. The clamping plate is rotatably connected to the output end of the telescopic motor via a movable shaft in the center of the top. The adjusting guide rail allows for precise and convenient adjustment of the spinning wheels. However, this adjustment method has the following drawbacks in actual use: it uses the adjusting guide rail for horizontal reciprocating adjustment of the spinning wheels, resulting in a limited adjustment method that is not easily adaptable to different workpiece processing requirements. Furthermore, excessive friction can easily occur in the spinning area during the spinning process, leading to scratches and causing slight deformation of the workpiece due to increased temperature, affecting the processing effect.

[0004] Based on this, the present invention designs a spinning wheel adjustment device for a spinning machine to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a spinning wheel adjustment device for a spinning machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A spinning wheel adjustment device for a spinning machine includes a frame, on which clamping plates and top columns are respectively arranged. The frame contains two spinning wheels and two adjustment mechanisms. Each adjustment mechanism is located outside the spinning wheels and is used to adjust the horizontal position, vertical position, and tilt angle of the spinning wheels. Each adjustment mechanism includes a support block, a drive rod, and two electric push rods. The spinning wheels are hinged to the bottom of the support block. One end of one electric push rod is connected to the support block, and one end of the other electric push rod is movably connected to the outside of one spinning wheel via ball bearings. The ends of the electric push rods away from the spinning wheels are slidably connected to the frame. One end of the drive rod is connected to the top of the support block.

[0008] Furthermore, an annular box is installed on the top of the rotating wheel, and a set of oil guide grooves evenly distributed along its axis are opened on the top of the rotating wheel. A conduit is provided between the oil guide grooves and the annular box, and a cotton plate is provided inside the conduit.

[0009] Furthermore, the annular box is provided with an adjusting ring inside, and the adjusting ring has a set of adjusting holes that match the inner diameter of the conduit.

[0010] Furthermore, a rotating rod is rotatably connected to the annular box, a gear is installed at the bottom end of the rotating rod, and an annular tooth groove that meshes with the gear is opened on the inner wall of the adjusting ring. The rotating rod and the annular box rotate through friction.

[0011] Furthermore, an exhaust pipe is provided on the outer side of the support block, and one end of the exhaust pipe is bent.

[0012] Furthermore, a piston plate is installed at one end of the drive rod, and a piston tube that is slidably connected to the frame is sleeved on the outer side of the piston plate;

[0013] Furthermore, an air pump is installed on the outside of the frame, a three-way pipe is installed at the output end of the air pump, one end of the piston pipe is connected to one end of the three-way pipe, one end of the exhaust pipe is connected to the three-way pipe, and solenoid valves are installed on the outside of both ends of the three-way pipe and the outside of the exhaust pipe.

[0014] Furthermore, a spring is installed on one side of the piston plate, and one end of the spring is installed inside the piston tube. Beneficial effects

[0015] 1. Activate the top electric push rod to move the support block horizontally, thus adjusting the horizontal position of the rotating wheel. Use the drive rod to move the support block, which allows the rotating wheel to move vertically. When it is necessary to adjust the tilt angle of the rotating wheel, the bottom electric push rod can be used to drive the docking shaft on the rotating wheel to rotate and adjust it along the intersection point inside the support block. This allows for diverse adjustments to the horizontal, vertical, and tilt angles of the rotating wheel to meet different processing needs.

[0016] 2. During the spinning process, the centrifugal force generated by the rotation of the spinning wheel will drive the lubricating oil in the annular box outward along the guide tube. The oil then enters the oil guide groove and flows to the spinning area. By injecting lubricating oil, excessive friction is reduced, thereby reducing the occurrence of scratches and workpiece deformation due to temperature rise, and ensuring the processing effect.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4A spinning wheel adjustment device for a spinning machine includes a frame 100, on which clamps and top columns are respectively provided. Two spinning wheels 200 are disposed inside the frame 100. The device also includes two adjustment mechanisms 300, located outside the spinning wheels 200 and used to adjust the horizontal, vertical, and tilt angles of the spinning wheels 200. Each adjustment mechanism 300 includes a support block 310, a drive rod 320, and two electric push rods 330. The spinning wheel 200 is hinged to the lower part of the support block 310. One end of one electric push rod 330 is connected to the support block 310, and one end of the other electric push rod 330 is movably connected to the outside of one spinning wheel 200 via ball bearings. The ends of the electric push rods 330 away from the spinning wheel 200 are slidably connected to the frame 100. One end of the drive rod 320 is connected to the top of the support block 310.

[0027] In this embodiment of the utility model, when performing spinning operations, the user can use the adjustment mechanism 300 to pre-adjust the horizontal position, vertical position and tilt angle of the two spinning wheels 200. Then, the workpiece is placed between the clamping plate and the top column, and the positioning push rod on the clamping plate drives its movement to clamp the workpiece. Then, the servo motor at the bottom of the top column operates to drive the workpiece to rotate, and then the spinning operation is performed with the spinning wheels 200.

[0028] In this embodiment of the invention, during the adjustment process, when it is necessary to adjust the horizontal position of the rotating wheel 200, such as... Figure 1 As shown, the top electric push rod 330 is activated, causing the support block 310 and the rotating wheel 200 to move horizontally. When the vertical position of the rotating wheel 200 needs to be adjusted, the support block 310 is driven by the drive rod 320 to move, causing the rotating wheel 200 to move vertically. When the tilt angle of the rotating wheel 200 needs to be adjusted, the bottom electric push rod 330 is operated to push the docking shaft on the rotating wheel 200 to move, causing it to rotate and adjust along the intersection point inside the support block 310.

[0029] In some embodiments, such as Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, an annular box 210 is installed on the top of the rotating wheel 200, and a set of oil guide grooves 220 evenly distributed along its axis are opened on the top of the rotating wheel 200. A conduit 230 is provided between the oil guide grooves 220 and the annular box 210, and a cotton board is provided inside the conduit 230.

[0030] During the spinning process, the centrifugal force generated by the rotation of the spinning wheel 200 will drive the lubricating oil in the annular box 210 outward along the guide tube 230. The use of cotton plates can slow down the oil discharge speed without affecting the oil discharge operation. The oil that enters the oil guide groove 220 will then flow to the spinning operation area, thereby reducing the frictional resistance between the spinning wheel 200 and the workpiece.

[0031] In this embodiment of the utility model, an adjusting ring 211 is provided inside the annular box 210. The adjusting ring 211 has a set of adjusting holes 212 that match the inner diameter of the guide tube 230. The user can pre-drive the adjusting ring 211 to move according to the tilt of the rotating wheel 200 and the type of workpiece. When the tilt of the rotating wheel 200 is greater, the contact changes from point contact to surface contact, thereby increasing the required amount of lubricating oil. The user can drive the adjusting holes 212 on the adjusting ring 211 to be misaligned with the guide tube 230, thereby controlling the amount of oil discharged.

[0032] In this embodiment of the utility model, a rotating rod 213 is rotatably connected to the annular box 210, and a gear 214 is installed at the bottom end of the rotating rod 213. The inner wall of the adjusting ring 211 is provided with an annular tooth groove that meshes with the gear 214. The rotating rod 213 and the annular box 210 rotate by friction. The user can rotate the rotating rod 213. Since the gear 214 meshes with the tooth groove, the adjusting ring 211 can be driven to complete the adjustment operation.

[0033] In this embodiment of the utility model, an exhaust pipe 311 is provided on the outer side of the support block 310. One end of the exhaust pipe 311 is bent. By using the exhaust pipe 311, some gas can be guided along its bent end to the spinning operation area. On the one hand, the gas can be used to form an airflow layer that pushes the lubricating oil, ensuring the lubricating oil introduction effect. On the other hand, the temperature of the spinning area can be reduced, reducing the occurrence of workpiece heating deformation.

[0034] It should be noted that by using the pneumatic adjustment support block 310, the accuracy and response speed of the adjustment can be improved by controlling the air intake, and the excess gas can also be used for the above-mentioned operations.

[0035] In this embodiment of the present invention, a piston plate 321 is installed at one end of the drive rod 320, and a piston tube 322 is slidably connected to the frame 100 on the outer side of the piston plate 321. Gas is introduced into the piston tube 322, and then the gas will push the piston plate 321 and the drive rod 320 to move, thereby causing the support block 310 to drive the corresponding rotating wheel 200 to complete the vertical position adjustment.

[0036] In this embodiment of the utility model, an air pump 110 is provided on the outside of the frame 100. A three-way pipe 111 is installed at the output end of the air pump 110. One end of the piston pipe 322 is connected to one end of the three-way pipe 111. One end of the exhaust pipe 311 is connected to the three-way pipe 111. Solenoid valves are installed on the outer sides of both ends of the three-way pipe 111 and the outer side of the exhaust pipe 311. When the air pump 110 is started, external gas can be introduced into the three-way pipe 111. During adjustment, the corresponding solenoid valve can be opened to introduce the gas in the three-way pipe 111 into the interior of the corresponding piston pipe 322. After the adjustment is completed, the corresponding solenoid valve is closed, and then the solenoid valve on the exhaust pipe 311 is opened to introduce gas into the interior of the exhaust pipe 311.

[0037] In this embodiment of the present invention, a spring 323 is installed on one side of the piston plate 321. One end of the spring 323 is installed inside the piston tube 322. When it is necessary to adjust the rotating wheel 200 upward, the corresponding solenoid valve can be opened. Then, the elastic deformation force of the spring 323 is used to pull the piston plate 321 and the drive rod 320 to reset, so that the support block 310 and the rotating wheel 200 are driven upward.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
