Description

Technical Field

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

[0002] A vertical spinning machine is a metal plastic forming equipment with a vertically arranged spindle. It is mainly used for processing rotating workpieces such as cylindrical parts and hubs. The spinning roller is usually fixed on the spinning machine by bolts and nuts. The rotating spinning roller spins the surface of the metal workpiece to form the required metal shape.

[0003] According to the search, the Chinese patent "A fixing device for a spinning wheel" (authorization announcement number "CN214517015U") uses the cooperation of the spinning wheel shaft and the locking screw to hide the screw head inside the spinning wheel, thus fixing the spinning wheel to the bracket. This can prevent the screw head from contacting the spinning part, which would cause defects in the spinning part and improve product quality.

[0004] In the aforementioned application, the vibration force generated by the rotating wheel during the application of pressure is easily transmitted to the surface of the locking screw, which can easily cause the locking screw to loosen, causing the screw head to come into contact with the spun part, thereby affecting the processing effect on the workpiece.

[0005] Based on this, the present invention designs a spinning wheel fixing device for a vertical spinning machine to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a spinning wheel fixing device for a vertical spinning machine.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A spinning wheel fixing device for a vertical spinning machine includes a mounting frame. Two rotating shafts are rotatably connected to the inner wall of the mounting frame. A bolt is threaded onto the inner wall of one of the rotating shafts. A limit rod is slidably connected to the inner wall of the rotating shaft. The device also includes an anti-loosening mechanism. The anti-loosening mechanism includes a shifting plate slidably connected to the inner wall of one of the rotating shafts. A friction block is rotatably connected to the inner wall of the shifting plate. A rubber sheet is fixedly connected to one end of the shifting plate, and the other end of the rubber sheet is fixedly connected to the inner wall of one of the rotating shafts. Several first right-angled blocks are fixedly connected to the top of the friction block. An iron block is slidably connected to the inner wall of one of the rotating shafts, and several second right-angled blocks are fixedly connected to the bottom of the iron block.

[0009] Furthermore, the iron block has a magnetic ring magnetically attached to its end, the bottom end of which is fixedly connected to the inner wall of one of the rotating shafts, and a sealing block is slidably connected to the inner wall of one of the rotating shafts, with the bottom of the sealing block contacting the top of the iron block.

[0010] Furthermore, one end of the transfer plate is fixedly connected to two baffles, and the upper surface of the friction block is fixedly connected to a driven block.

[0011] Furthermore, a stop bar is slidably connected to the inner wall of the mounting frame.

[0012] Furthermore, a locking rod is slidably connected to the inner wall of the mounting frame, and the surface of the locking rod is engaged with the inner wall of the stop bar.

[0013] Furthermore, a slider is fixedly connected to the surface of the transfer plate, and the surface of the slider is slidably connected to the inner wall of one of the rotating shafts.

[0014] Furthermore, a connecting rope is fixedly connected to one side of the sealing block, and the other end of the connecting rope is fixedly connected to the surface of one of the rotating shafts.

[0015] Furthermore, the surface thread of the bolt is connected to the inner wall of the limiting rod. Beneficial effects

[0016] By cooperating with the friction block and the rubber sheet, the resistance to the friction block moving away from the bolt is increased. By cooperating with the first right-angle block, the iron block and the second right-angle block, the friction block is limited in one direction, thus ensuring that the friction block is stably in contact with one end of the bolt. Compared with the existing spinning wheel for spinning metal workpieces, which is prone to causing the locking screw to loosen, this method prevents the bolt from loosening by blocking and locking the bolt, thus ensuring the processing effect of the workpiece.

[0017] The magnetic ring attracts the iron block, causing the inclined surface of the second right-angled block to stably abut against the inclined surface of the first right-angled block, and the straight surface of the second right-angled block to stably abut against the straight surface of the first right-angled block. The sealing block is inserted into one of the rotating shafts, and the bottom of the sealing block contacts the top of the iron block, thereby locking the iron block and ensuring the stable positioning of the friction block, thus ensuring the stable sealing and locking of the bolt.

Detailed Implementation

[0025] 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.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 A spinning wheel fixing device for a vertical spinning machine includes a mounting frame 1. Two rotating shafts 2 are rotatably connected to the inner wall of the mounting frame 1. A bolt 4 is threadedly connected to the inner wall of one of the rotating shafts 2. A limit rod 3 is slidably connected to the inner wall of the rotating shaft 2. The device also includes an anti-loosening mechanism 5. The anti-loosening mechanism 5 includes a shifting plate 51 slidably connected to the inner wall of one of the rotating shafts 2. A friction block 52 is rotatably connected to the inner wall of the shifting plate 51. A rubber sheet 53 is fixedly connected to one end of the shifting plate 51. The other end of the rubber sheet 53 is fixedly connected to the inner wall of one of the rotating shafts 2. Several first right-angled blocks 54 are fixedly connected to the top of the friction block 52. An iron block 55 is slidably connected to the inner wall of one of the rotating shafts 2. Several second right-angled blocks 56 are fixedly connected to the bottom of the iron block 55.

[0028] Vertical spinning machines typically consist of a casing, a spindle system, a spinning wheel drive system, a control system, and auxiliary devices.

[0029] Spindle system: Includes spindle, bearings, drive motor, etc. Its main function is to drive the workpiece to rotate. Its speed, rotation accuracy and load capacity have an important impact on the processing quality and efficiency.

[0030] Rotary wheel drive system: enables the movement and adjustment of the rotary wheel in multiple directions, and can precisely control the position and attitude of the rotary wheel.

[0031] Chassis: It is the basic component of the spinning machine, providing support and a mounting platform for other components.

[0032] Control system: This is the core of the spinning machine, employing a CNC system to precisely control parameters such as spindle speed, spinning head movement trajectory, feed speed, and pressure. Operators can input machining programs through the operating interface to achieve automated machining.

[0033] Auxiliary devices include tailstocks, which hold one end of the workpiece in place to ensure its stability during rotation; lubrication systems and cooling systems, which provide lubrication for the moving parts of the equipment and reduce the temperature during processing.

[0034] In this embodiment of the utility model, when it is necessary to fix the rotating wheel, the rotating wheel is placed in the mounting frame 1, and the limiting rod 3 is sequentially inserted into one of the rotating shafts 2, the rotating wheel and the other rotating shaft 2, so that the rotating wheel is initially positioned in the mounting frame 1. The bolt 4 is threaded into one of the rotating shafts 2 and the limiting rod 3 using an electric wrench. After rotating the friction block 52 to a suitable angle, the friction block 52 is pushed to move and be inserted into one of the rotating shafts 2. The movement of the friction block 52 drives the first right-angle block 54 to move, so that the inclined surface of the first right-angle block 54 moves to contact the inclined surface of the second right-angle block 56, so that one end of the friction block 52 abuts against one end of the bolt 4, so that the inclined surface of the first right-angle block 54 contacts the inclined surface of the second right-angle block 56, and the straight surface of the first right-angle block 54 contacts the straight surface of the second right-angle block 56. The friction block 52 is unidirectionally moved and limited, so that the rotating wheel is stably installed on the mounting frame 1.

[0035] At this point, the metal blank is installed on the main shaft of the spinning machine and positioned. The main shaft drives the blank to rotate at high speed, while simultaneously driving the spinning wheel to rotate, applying pressure to the metal blank and moving along a pre-set trajectory. Under the pressure and friction of the spinning wheel, the metal blank gradually undergoes plastic flow and deformation, eventually conforming to the mold or forming the required shape according to the movement trajectory of the spinning wheel.

[0036] In this embodiment of the utility model, the friction block 52 and the rubber sheet 53 cooperate with each other to increase the resistance of the friction block 52 moving away from the bolt 4. The first right-angle block 54, the iron block 55 and the second right-angle block 56 cooperate with each other to limit the unidirectional movement of the friction block 52, thereby ensuring that the friction block 52 stably abuts against one end of the bolt 4, thus achieving the sealing and locking of the bolt 4, preventing the bolt 4 from loosening, and ensuring the processing effect of the workpiece.

[0037] In some embodiments, such as Figure 3-4 As shown, in a preferred embodiment of this utility model, a magnetic ring 57 is magnetically attracted to the end of the iron block 55. The bottom end of the magnetic ring 57 is fixedly connected to the inner wall of one of the rotating shafts 2. A blocking block 58 is slidably connected to the inner wall of one of the rotating shafts 2. The bottom of the blocking block 58 contacts the top of the iron block 55. Two blocking rods 512 are fixedly connected to one end of the shifting plate 51. A driven block 511 is fixedly connected to the upper surface of the friction block 52. A slider 510 is fixedly connected to the surface of the shifting plate 51. The surface of the slider 510 is slidably connected to the inner wall of one of the rotating shafts 2. A connecting rope 59 is fixedly connected to one side of the blocking block 58. The other end of the connecting rope 59 is fixedly connected to the surface of one of the rotating shafts 2. The surface of the bolt 4 is threadedly connected to the inner wall of the limiting rod 3. Both the friction block 52 and the blocking block 58 are rubber components.

[0038] In this embodiment of the utility model, the interaction between the driven block 511 and the blocking rod 512 limits the rotation angle of the friction block 52 within the transfer plate 51, ensuring that the friction block 52 can be accurately and quickly inserted into one of the rotating shafts 2.

[0039] The magnetic ring 57 attracts the iron block 55, causing the inclined surface of the second right-angle block 56 to stably abut against the inclined surface of the first right-angle block 54, and the straight surface of the second right-angle block 56 to stably abut against the straight surface of the first right-angle block 54. The sealing block 58 is inserted into one of the rotating shafts 2, and the bottom of the sealing block 58 contacts the top of the iron block 55, thereby locking the iron block 55 and ensuring the stable positioning of the friction block 52, thus ensuring the stable sealing and locking of the bolt 4.

[0040] In some embodiments, such as Figure 2 As shown, in a preferred embodiment of the present invention, a stop bar 513 is slidably connected to the inner wall of the mounting frame 1, and a locking bar 514 is slidably connected to the inner wall of the mounting frame 1, with the surface of the locking bar 514 engaging with the inner wall of the stop bar 513.

[0041] In this embodiment of the utility model, the stop bar 513 limits the placement of the rotating wheel within the mounting frame 1, ensuring that the limit bar 3 is accurately and quickly inserted into the rotating wheel.

[0042] It should be noted that the mounting frame 1, rotating shaft 2, limiting rod 3, bolt 4, iron block 55 and magnetic ring 57 mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs, and will not be elaborated here.

[0043] 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.
