Description

Technical Field

[0001] The invention relates to the technical field of bushing support equipment, and in particular to a bushing support device for a concave and convex roller of a winding machine. Background Art

[0002] The bushing acts as a gasket in the valve application field. The bushing is inside the valve cover and wraps the valve stem. Generally, corrosion-resistant materials such as polytetrafluoroethylene or graphite are used for sealing. It has good resilience and can bend without deformation. At the same time, it can maintain toughness and resist repeated impacts. It has wear-resistant self-lubricating properties, providing better working performance than bronze, cast iron, carbon steel and phenolic laminates in oil-free lubrication applications, reducing consumption, saving energy, absorbing noise and reducing shock. The modulus of MC nylon is much smaller than that of metal, and the vibration attenuation is large, providing a practical way to prevent noise that is better than metal. Compared with metal, MC nylon has low hardness and does not damage the wear parts. The existing winding machine requires the use of a concave and convex roller bushing structure, but there are still certain deficiencies when using it.

[0003] A concave-convex roller bushing support device for a roll forming machine in the prior art has the following disadvantages:

[0004] 1. In the prior art, a concave-convex roller bushing support device for a lap forming machine lacks a stable supporting structure when the concave-convex roller and the bushing are connected and installed during use. The shaking generated when the device is working can easily lead to a deviation in the connection between the two, affecting the normal operation of the device.

[0005] 2. In the prior art, a concave-convex roller bushing support device for a winding machine has a relatively simple structure of auxiliary support devices for multiple pairs of bushings when in use, lacks a convenient installation structure, is relatively complicated to install, and is not practical enough. Summary of the invention

[0006] The object of the present invention is to provide a concave-convex roller bushing support device for a lap forming machine to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a concave-convex roller bushing support device for a winding machine, comprising a limit clamp a, the tail end of the limit clamp a is connected to the limit clamp b through a rotating shaft, a connecting seat is installed on one side of the outer surface of the limit clamp a, a connecting piece is installed on one side of the outer surface of the limit clamp b, the interiors of the connecting piece and the connecting seat are both threaded with fixing bolts, the inner wall of the limit clamp is clamped with a limit ring, the inner wall of the limit ring is provided with a cylindrical roller, and the outer surface of the cylindrical roller is connected to a retaining frame.

[0008] Preferably, a connecting piece and a mounting clip are sequentially installed from left to right in the middle of the outer surface of the limiting clamp b, and a threaded seat is threadedly connected to one side of the limiting clamp b.

[0009] Preferably, a bushing is movably connected to the inner wall of the cylindrical roller, and a limiting rod is inserted into the interior of the bushing.

[0010] Preferably, a positioning block is installed on the outer surface of the limiting ring, and positioning grooves are formed on the inner sides of the limiting clip a and the limiting clip b.

[0011] Preferably, a lengthening rod is threadedly connected to the top of the limiting rod, and concave-convex rollers are arranged on the outer surfaces of the limiting rod and the lengthening rod.

[0012] Preferably, connection grooves are formed on both sides of the threaded seat, and stress blocks are installed on the inner walls of the connection grooves.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. Through the arrangement of the limiting clip a and the limiting clip b, the limiting clip a and the limiting clip b can rotate through the rotating shaft, so as to play a role in limiting and clamping the limiting ring. After the limiting clip a and the limiting clip b are closed, through the arrangement of the connection seat fixing bolt and the connection piece, the closed limiting clip a and the limiting clip b are connected and fixed, so as to improve the stability of clamping the limiting ring. Between the limiting ring and the limiting clip a and the limiting clip b, through the arrangement of the positioning block and the positioning groove, when the limiting clip a and the limiting clip b are closed, the positioning block and the positioning groove are embedded in each other, so as to add high efficiency and stability to the clamping of the limiting ring. Inside the limiting ring, through the arrangement of the cage and the cylindrical roller, the cage plays a role in limiting the movement of the cylindrical roller. By the rotation of the cylindrical roller, the rotation of the bushing is driven, and then the rotation of the limiting rod is assisted. Through the close fit between the limiting ring and the limiting clip a and the limiting clip b, the support for the rotation of the bushing is added.

[0015] 2. Through the arrangement of the connection piece and the mounting clip, the opposite limiting clip b can be installed and connected through the threaded seat. The connection piece and the mounting clip are inserted into each other, and the connection piece and the mounting clip are adapted to the rotation of the threaded seat. Then, after the connection piece and the mounting clip are inserted, they can be fixed by bolts, so as to ensure the stability of the connection, thus adding a convenient and fast installation method for the device. Through the arrangement of the stress block, by reducing the contact area, the extrusion force on both sides of the threaded seat is buffered, and the practicability of the device is increased.

[0024] Please refer to Figures 1-4 , an embodiment provided by the present invention, a support device for the concave-convex roller bushing of a coiling machine, includes a limit clip a1. The tail end of the limit clip a1 is connected to a limit clip b2 through a rotating shaft. A connection piece 9 and an installation clip 10 are sequentially installed on the middle part of the outer surface of the limit clip b2 from left to right. One side of the limit clip b2 is threadedly connected to a threaded seat 11. Connection grooves 16 are opened on both sides of the threaded seat 11, and force-bearing blocks 17 are installed on the inner walls of the connection grooves 16.

[0025] Through the settings of the connecting piece 9 and the mounting clip 10, the opposite limiting clips b2 can be installed and connected through the threaded seat 11. The connecting piece 9 and the mounting clip 10 are inserted into each other, and the connecting piece 9 and the mounting clip 10 are adapted to the rotation of the threaded seat 11. Then, after the connecting piece 9 and the mounting clip 10 are inserted, the two can be fixed by bolts, thus ensuring the stability of the connection, thereby adding a convenient and fast installation method for the device. Through the setting of the force-receiving block 17, by reducing the contact area, it plays a buffering role in the extrusion forces on both sides of the threaded seat 11, adding the practicality of the device.

[0026] On one side of the outer surface of the limiting clip a1, a connecting seat 3 is installed. On one side of the outer surface of the limiting clip b2, a connecting piece 4 is installed. Fixing bolts 5 are threadedly penetrated and installed inside both the connecting piece 4 and the connecting seat 3. A limiting ring 6 is clamped inside the limiting clip. A positioning block 14 is installed on the outer surface of the limiting ring 6. Positioning grooves are provided on the inner sides of both the limiting clip a1 and the limiting clip b2.

[0027] Through the settings of the limiting clip a1 and the limiting clip b2, the limiting clip a1 and the limiting clip b2 can rotate through a rotating shaft, thereby playing a role in limiting and clamping the limiting ring 6. After the limiting clip a1 and the limiting clip b2 are closed, through the settings of the connecting seat 3, the fixing bolt 5 and the connecting piece 4, the closed limiting clip a1 and the limiting clip b2 are connected and fixed, thereby ensuring the stability of clamping the limiting ring 6. Between the limiting ring 6 and the limiting clip a1 and the limiting clip b2, through the settings of the positioning block 14 and the positioning groove, when the limiting clip a1 and the limiting clip b2 are closed, the positioning block 14 and the positioning groove are embedded in each other, thereby adding the high-efficiency stability of holding the limiting ring 6. Inside the limiting ring 6, through the settings of the cage 8 and the cylindrical roller 7, the cage 8 plays a role in limiting the movement of the cylindrical roller 7. Through the rotation of the cylindrical roller 7, the rotation of the bushing 12 is driven, and then the rotation of the limiting rod 13 is assisted. Through the tight fit between the limiting ring 6 and the limiting clip a1 and the limiting clip b2, the support for the rotation of the bushing 12 is added.
