DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: See Figure 1-4 The utility model provides a technical solution: a stable clamping mechanism for shaft core processing, including a support plate 1, a pillar 4 is connected to the bottom of the inner cavity of the support plate 1, a placement groove 5 is opened on the front of the pillar 4, a winding groove 6 is opened on one side of the pillar 4, a movable groove 7 is opened between the support plate 1 and the pillar 4, a bottom ring 8 is connected to the top of the pillar 4, a pressure ring 9 is movably arranged on the top of the bottom ring 8, a connecting rod 10 is connected to the top of the pressure ring 9, a limiting ring 11 is arranged on the top of the connecting rod 10, a telescopic rod 15 is connected to the bottom of the inner cavity of the movable groove 7, a mounting plate 17 is connected to the top of the telescopic rod 15, a pressing plate 18 is arranged on the top of the mounting plate 17, and a through hole 14 is opened through the front of the support plate 1.

[0023] Among them, screw holes 19 are opened through the top of the mounting plate 17 and the pressure plate 18, and the pressure plate 18 is fixedly connected to the mounting plate 17 through the screw holes 19. The connecting rod 10 passes through the top of the support plate 1, the limit ring 11 is located above the support plate 1, and a small winding machine is built into the placement groove 5.

[0024] In this embodiment, when in use, the winder is placed in the inner cavity of the placement groove 5, and one end of the winding belt built into the winder is pulled out, and moves in the movable groove 7 through the winding groove 6, and then the winding belt passes through the gap between the pressure ring 9 and the support plate 1, and contacts the pressure plate 18. At this time, one end of the winding belt is placed between the pressure plate 18 and the mounting plate 17, and a screw is passed through the screw hole 19 to fix one end of the winding belt through the pressure plate 18 and the mounting plate 17. Then, the shaft core is placed on the top of the bottom ring 8 through the through hole 14. At this time, the winding belt is tightened by the winder, and the winding belt presses down the pressure ring 9 above the pressure ring 9, so that the pressure ring 9 is pressed above the shaft core, thereby fixing the position of the shaft core.

[0025] A cover plate 2 is disposed on the front of the support plate 1 , and connection holes 3 are provided on one side of the cover plate 2 and the support plate 1 , and the cover plate 2 is fixedly connected to the support plate 1 through the connection holes 3 .

[0026] In this embodiment, after the winder and the winding belt are installed, the cover plate 2 is placed on the front of the support plate 1, and the screws are passed through the connecting holes 3 so that the connection between the cover plate 2 and the support plate 1 is fixed, thereby preventing dust from entering the device, and the device can be easily maintained through the screw connection.

[0027] The outer ring of the telescopic rod 15 is sleeved with a spring 16 , and the spring 16 is located below the mounting plate 17 .

[0028] In this embodiment, the telescopic rod 15 is located at the bottom of the mounting plate 17. When the winder starts to unwind, the winding belt is loosened and loses its pull on the spring 16. At this time, the spring 16 pulls the winding belt down through the mounting plate and the pressure plate 18, thereby preventing the winding belt from accumulating in the movable groove 7. The function of the spring 16 is to limit the movement trajectory of the winding belt.

[0029] The outer ring of the connecting rod 10 is sleeved with a return spring 12 , and the return spring 12 is located above the support plate 1 . There are two connecting rods 10 in total, and they are on the same horizontal line.

[0030] In this embodiment, the reset spring 12 is located between the limit ring 11 and the support plate 1. When the shaft core is processed and the winder starts to unwind, the winding belt is loosened, and then the reset spring 12 starts to rebound and pulls up the connecting rod 10 through the limit ring 11. The connecting rod 10 drives the pressure ring 9 to move upward, so that the shaft core loses pressure, thereby facilitating its removal from the device.

[0031] A plurality of rubber strips 13 are disposed on the bottom of the pressure ring 9 and the top of the bottom ring 8 .

[0032] In this embodiment, the rubber strip 14 can increase the friction between the device and the shaft core, so that the connection between the device and the shaft core is more secure, and the rubber strip 14 is relatively soft, which can prevent the device from scratching the surface of the shaft core.

[0033] Among them, the bottom of the support plate 1 is connected to a base 20, one end of the base 20 is provided with a mounting groove 21, the inner cavity of the mounting groove 21 is movably connected with an insertion rod 22, one end of the insertion rod 22 is connected to a second base 24, and one side of the base 20 and the insertion rod 22 are provided with a limiting hole 23.

[0034] In this embodiment, there are a plurality of limiting holes 23, and the plurality of limiting holes 23 are of the same size and are located on the same horizontal line. The base 20 and the insertion rod 22 can be connected by passing screws through the limiting holes 23 opened by the base 20 and the insertion rod 22. This arrangement can control the distance between the two support plates 1, thereby facilitating the clamping of shaft cores of different lengths.

[0035] Working principle: When in use, the shaft core passes through the through hole 14, and the winding belt is wound by the winding machine built into the winding groove 6. At this time, the winding belt presses down the pressure ring 9, so that the pressure ring 9 squeezes the shaft core above the shaft core, thereby fixing the position of the shaft core. After the processing is completed, when the winding machine unwinds, the reset spring 12 begins to rebound and pulls up the connecting rod 10 through the limit ring 11. The connecting rod 10 drives the pressure ring 9 to move upward, so that the shaft core loses pressure, thereby facilitating its removal from the device.

[0036] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
