Description

Technical Field

[0001] This utility model relates to the field of belt pulley processing, and specifically to an adjustment mechanism for a spinning device used in belt pulley processing. Background Technology

[0002] In the field of pulley manufacturing, spinning is widely used in the mass production of pulleys because it can achieve high-precision machining of complex structures such as rims and grooves in a single process. This process uses a spinning die to apply continuous radial and axial pressure to the blank, causing the metal blank to undergo plastic deformation during rotation, gradually conforming to the die contour, and finally forming a pulley structure with specific dimensions and shape.

[0003] When machining pulley blanks of different diameters, the original fixing and clamping components need to be disassembled and replaced with tooling of the corresponding size, including positioning sleeves. Since the installation reference of different specifications of tooling is different, the coaxiality of the blank and the spinning spindle needs to be recalibrated after each replacement. The calibration process relies on manual measurement using a dial indicator, which is time-consuming and reduces the working efficiency of the equipment.

[0004] Therefore, it is necessary to invent an adjustment mechanism for a spinning device used in pulley processing to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustment mechanism for a spinning device used in pulley processing. By setting an adjustment assembly consisting of a worm gear, a worm, and multiple sets of adjustment frames, synchronous radial adjustment of pulley blanks of different diameters can be achieved. This solves the problems in the prior art where disassembling and replacing tooling is required when processing blanks of different diameters, coaxiality is reliance on manual calibration, and the operation is time-consuming and inefficient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjusting mechanism for a spinning device used in pulley processing, comprising... Mounting base for supporting the overall device. A connecting base is fixedly mounted on the upper part of the mounting base by bolts. The upper part of the connecting base is set as a conical surface, and a circular hole is opened in the middle of the connecting base. The adjustment assembly includes multiple sets of adjustment brackets slidably connected to the lower inner wall of the connecting seat. The lower surface of the adjustment bracket slides on the upper surface of the mounting seat. A worm gear is rotatably connected to the upper inner wall of the mounting seat via a support column and a bearing. A threaded protrusion is fixedly connected to the upper part of the worm gear. The lower part of the multiple sets of adjustment brackets is provided with threaded grooves that slide with the threaded protrusion. A worm that meshes with the worm gear is rotatably connected to the inner wall of the mounting seat. An operating head is fixedly connected to the front side of the worm.

[0008] Preferably, the bearing is fixedly connected to the inner wall of the worm gear, the support column is fixedly connected to the middle of the mounting base, and the support column is inserted into the inner ring of the bearing.

[0009] Preferably, a pressure block is fixedly connected to the lower part of the connecting seat near the upper part of the worm, and the lower part of the pressure block is attached to the rod-shaped outer side of the worm.

[0010] Preferably, the front side of the operating head is provided with a regular hexagonal groove.

[0011] Preferably, a limiting component is provided on the outer side of the operating head. The limiting component includes a limiting groove, and multiple sets of the limiting groove are formed around the outer side of the operating head.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1 - Figure 3 The adjustment mechanism for a spinning device used in pulley processing, as shown, includes a mounting base 1 and an adjustment assembly 3, specifically: Mounting seat 1 is used to support the entire device and serves as the load-bearing foundation for the entire adjustment mechanism. It is fixed to the spinning equipment frame with bolts and provides a stable mounting platform for components such as connecting seat 2 and adjustment assembly 3. The upper part of mounting seat 1 is fixed with connecting seat 2 by bolts. The upper part of connecting seat 2 is set with a tapered surface, which can guide the pulley blank to be positioned quickly and ensure that the center of the blank is aligned with the spinning spindle. A round hole is opened in the middle of connecting seat 2 to accommodate the movement of multiple sets of adjustment frames 31. The adjusting assembly 3 includes multiple adjusting frames 31 slidably connected to the lower inner wall of the connecting seat 2 for supporting the pulley blank. The lower surface of the adjusting frame 31 slides on the upper surface of the mounting seat 1. A worm gear 32 is rotatably connected to the upper inner wall of the mounting seat 1 via a support column 35 and a bearing 34. The worm gear 32 converts its own rotational motion into the radial linear motion of the adjusting frame 31. A threaded protrusion 33 is fixedly connected to the upper part of the worm gear 32. By simultaneously engaging with the threaded grooves 38 of the multiple adjusting frames 31, it ensures that all adjusting frames 31 move synchronously, avoiding blank positioning deviation caused by uneven force. The lower part of the multiple adjustment brackets 31 is provided with a threaded groove 38 that slides with the threaded protrusion 33. The inner wall of the mounting base 1 is rotatably connected to a worm 36 that meshes with the worm wheel 32. This is the input component for adjusting power. It can transmit the rotational motion of the operating head 37 to the worm wheel 32, and realize adjustment by using the deceleration characteristic. It also has a reverse self-locking function to prevent the position from loosening after adjustment. The operating head 37 is fixedly connected to the front side of the worm 36. The front side of the operating head 37 is provided with a regular hexagonal groove, which can be adapted to wrenches, hex screwdrivers or automatic drive devices, so that the operator can easily apply rotational force.

[0019] like Figure 2 and Figure 3As shown, the adjusting bracket 31 is L-shaped, and the vertical ends of multiple L-shaped adjusting brackets 31 form a cylinder. The bearing 34 is fixedly connected to the inner wall of the worm gear 32, which can reduce the frictional resistance when the worm gear 32 rotates and ensure smooth transmission. The support column 35 is fixedly connected to the middle of the mounting base 1, serving as the rotation axis of the worm gear 32. The bearing 34 forms a radial positioning of the worm gear 32, preventing the worm gear 32 from being eccentric or tilted during rotation, and ensuring stable meshing between the threaded protrusion 33 and the adjusting bracket 31. The support column 35 is inserted into the inner ring of the bearing 34. A pressure block 5 is fixedly connected to the lower part of the connecting base 2 near the upper part of the worm 36. The lower part of the pressure block 5 is attached to the rod-shaped outer side of the worm 36, and the axial movement of the worm 36 is restricted by the preload.

[0020] like Figure 2 and Figure 4 As shown, a limiting component 4 is provided on the outer side of the operating head 37. The limiting component 4 includes a limiting groove 41, which has multiple sets. The multiple sets of limiting grooves 41 are arranged around the outer side of the operating head 37 and engage with the bent part of the elastic member 42. The mechanical engagement restricts the circumferential rotation of the operating head 37 and enhances the positional stability after adjustment. An elastic member 42 is inserted into the lower side of the mounting base 1 near the operating head 37. The upper part of the elastic member 42 is bent. The bent part of the elastic member 42 engages with the inner wall of the limiting groove 41. The elastic member 42 is set as a spring plate, which does not affect the active rotation of the operating head 37 and can lock the operating head 37 when there is no external force to prevent positional displacement caused by vibration.

[0021] The working principle of this practical system is as follows: First, the mounting base 1 is fixed to the frame of the spinning equipment with bolts. The connecting base 2 is fixed to the upper part of the mounting base 1 with its conical surface facing upwards, which facilitates the quick insertion of the blank into the pulley and automatic alignment with the center. At this time, the vertical ends of multiple sets of L-shaped adjusting brackets 31 are combined to form a cylindrical space, which is used to support or clamp the inner wall of the blank.

[0022] When it is necessary to adapt to blanks of different diameters, a wrench or drive device is inserted into the hexagonal slot of the operating head 37. Rotating the operating head 37 drives the worm 36 to rotate, and the worm 36 meshes with the worm wheel 32, transmitting the rotational power to the worm wheel 32. Due to the reduction characteristics of the worm wheel 32 and the worm 36, the worm wheel 32 rotates around the support column 35 at a slower speed, and the support column 35 and the bearing 34 ensure smooth rotation.

[0023] The threaded protrusion 33 on the upper part of the worm gear 32 rotates synchronously with the worm gear 32 and meshes with the threaded groove 38 on the lower part of the adjusting frame 31, driving multiple sets of adjusting frames 31 to move synchronously radially along the lower inner wall of the connecting seat 2 and the upper surface of the mounting seat 1, thereby adapting to blanks of different specifications and improving the working efficiency of the equipment.

[0024] During the adjustment process, the limiting groove 41 on the outside of the operating head 37 cooperates with the elastic element 42 on the mounting base 1: every time it rotates a certain angle, the bent part of the elastic element 42 will be engaged into the corresponding limiting groove 41, and the position of the operating head 37 will be temporarily locked through mechanical engagement to prevent displacement due to vibration during the spinning process.

[0025] Finally, place the pulley blank on the conical surface of the connecting seat 2, with its inner wall fitting against the vertical end of the adjusting frame 31. After positioning, the spinning equipment can be started for processing.

[0026] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
