The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] First embodiment

[0026] See also Figure 1 to Figure 3 , Figure 1 It is a schematic diagram of the overall structure of the friction wheel processing and forming tooling of the first embodiment of the utility model. Figure 2 1 is a schematic cross-sectional view of the friction wheel processing and forming tooling of the first embodiment of the utility model along the positioning rod 108, Figure 3 The first embodiment of the present invention is a friction wheel processing tool Figure 2 Enlarged view of point A.

[0027] The utility model provides a processing and forming tool for a friction wheel: it includes a base plate 101 and a centering component, the centering component includes a connecting column 102, a support box 103, a rotating block, a rotating rod 104, a transmission block, a screw 105, a limiting arm 106, a support plate 107 and a positioning rod 108, the rotating block includes a rotating plate 109 and a handle 110, and the transmission block includes a first gear 111 and a second gear 112. The aforementioned scheme solves the problem that the position of the locating pin of the limit arm 106 of the aforementioned centering assembly is fixed, which results in the need to disassemble and install the limit arm 106 of a size corresponding to the wheel core 201 in order to achieve the centering operation of the wheel core 201 of different sizes. It can be understood that the aforementioned scheme can be used in the scenario where the position of the locating pin of the limit arm 106 needs to be adjusted accordingly when performing the centering operation on the wheel core 201 of different sizes. It can also be used to establish a space on the outside of the wheel core 201 to facilitate the application of glue in the space to solve the problem of obtaining the required friction wheel.

[0028] In this embodiment, the centering assembly is located above the base plate 101, and is used to adjust the position of the positioning pin of the limit arm 106 without disassembling or installing the limit arm 106, so that the positioning pin of the limit arm 106 can perform centering operations on the wheel core 201 of different sizes, thereby shortening the processing time of the friction wheel.

[0029] The connecting column 102 is arranged on the upper surface of the bottom plate 101, the supporting box 103 is arranged on the upper surface of the connecting column 102, the rotating block is used to rotate the rotating rod 104, the rotating rod 104 is rotatably connected with the supporting box 103 and passes through the supporting box 103, the transmission block is used to transmit the rotational force of the rotating rod 104 to the screw rod 105, the screw rod 105 is rotatably connected with the supporting box 103 and is located on the inner side of the supporting box 103, the limiting arm 106 is movably connected with the screw rod 105 and passes through the supporting box 103, the interior of the supporting box 103 is a hollow structure, the supporting box 103 has a circular through hole 204, and the rotating rod 104 passes through the circular through hole 204 of the supporting box 103 04. The screw rod 105 is located in the support box 103 and can rotate along its own axis in the support box 103. The support box 103 has a slot, and the limit arm 106 passes through the slot of the support box 103. The limit arm 106 is connected to the screw rod 105 by a thread. The rotation of the screw rod 105 along its own axis can drive the limit arm 106 to move laterally in the slot of the support box 103. The limit arm 106 has a positioning pin. Since the limit arm 106 can move laterally in the slot of the support box 103, the positioning pin of the limit arm 106 can be driven to move laterally outside the support box 103, thereby adjusting the position of the positioning pin of the limit arm 106.

[0030] Secondly, the rotating plate 109 is arranged at one end of the rotating rod 104 away from the supporting box 103; the handle 110 is arranged on a side of the rotating plate 109 away from the rotating rod 104. The handle 110 is held and rotated, thereby driving the rotating plate 109 to rotate along the axis of the rotating plate 109, and then driving the rotating rod 104 to rotate along the axis of the rotating rod 104. The outer side of the handle 110 is evenly distributed with anti-slip grooves. The anti-slip grooves of the handle 110 will increase the friction between the palm and the handle 110, thereby avoiding slipping when the user rotates the handle 110.

[0031] Again, the first gear 111 is arranged at one end of the rotating rod 104 away from the rotating plate 109 and is located on the inner side of the supporting box 103; the second gear 112 is meshed with the first gear 111 and is arranged on the outer side of the screw rod 105, the first gear 111 is meshed with the second gear 112, the first gear 111 and the second gear 112 are both bevel gears, and the first gear 111 and the second gear 112 are vertically arranged, and the rotating rod 104 is rotated along the axis of the rotating rod 104 in the circular through hole 204 of the supporting box 103, so that the first gear 111 can be driven to rotate along the axis of the first gear 111, and then the second gear 112 can be driven to rotate along the axis of the second gear 112.

[0032] Finally, the support plate 107 is arranged on a side of the support box 103 close to the handle 110; the positioning rod 108 is detachably connected to the support plate 107 and the rotating rod 104 respectively, and the positioning rod 108 passes through the support plate 107 and the rotating rod 104. Both the support plate 107 and the rotating rod 104 have a through hole 204, and the positioning rod 108 can be inserted into the through hole 204 of the support plate 107 and the rotating rod 104, so that the positioning rod 108 can limit the rotation position of the rotating rod 104 to avoid the rotating plate 109 from rotating when the handle 110 is not rotated.

[0033] When using the processing and forming tooling of the friction wheel of this embodiment, an anti-sticking film is laid on the top of the bottom plate 101, and then the wheel core 201 is placed on the bottom plate 101, and the opening 203 of the wheel core 201 is passed through the support box 103 and the limit arm 106, and then the handle 110 is held and rotated, thereby driving the rotating plate 109 to rotate along its own axis, and then driving the rotating rod 104 to rotate along its own axis, and the rotation of the rotating rod 104 along its own axis can drive the second gear 112 to rotate along its own axis, and then drive the first gear 111 to rotate along its own axis, and the rotation of the first gear 111 along its own axis can drive the screw 105 to rotate along its own axis in the support box 103, and then drive the limit arms 106 on the left and right sides outside the screw 105 to rotate in the support box 103. The limiting arms 106 on the left and right sides outside the screw rod 105 can move relative to or away from each other in the groove of the support box 103, thereby driving the positioning pins of the limiting arms 106 on the left and right sides to move relative to or away from each other outside the support box 103, thereby achieving simultaneous adjustment of the positions of the positioning pins of the limiting arms 106 on the left and right sides. When the positioning pins of the limiting arms 106 on the left and right sides are aligned with the two opposite sides of the wheel core 201, the wheel core 201 can be adjusted to the desired position. The position of the through hole 204 is aligned, and at the same time, when the locating pin of the limit arm 106 passes through the through hole 204, the locating pin of the limit arm 106 can center the wheel core 201. The position of the locating pin of the limit arm 106 can be adjusted simultaneously without disassembling or installing the limit arm 106, so that the locating pin of the limit arm 106 can perform centering operations on the wheel core 201 of different sizes, thereby shortening the processing time of the friction wheel.

Based on the first embodiment, the friction wheel processing and forming tool of the utility model further includes a locking assembly, and the locking assembly includes a first locking ring 113 , a second locking ring 114 and a locking bolt 115 .

[0036] In this embodiment, the locking assembly is located above the base plate 101. By setting the locking assembly, the locking assembly can establish a space outside the wheel core 201 to facilitate applying glue in the space to obtain the desired friction wheel.

[0037] Among them, the first locking ring 113 and the second locking ring 114 are both detachably connected to the base plate 101, and the first locking ring 113 and the second locking ring 114 are both located on the upper surface of the base plate 101. The first locking ring 113 and the second locking ring 114 are both semicircular in shape. The two first locking rings 113 and the second locking rings 114 can be combined together to form a complete circle. There is an annular space between the circular space formed by the first locking ring 113 and the second locking ring 114 and the pillow core, so that glue can be applied in the annular space to obtain the glue layer 202.

The threaded holes of the first locking ring 113 and the second locking ring 114 have the same size as the threaded holes of the base plate 101. The locking bolt 115 is connected to the first locking ring 113, the second locking ring 114 and the base plate 101 through threads, so that the locking bolt 115 can be tightened or loosened in the threaded holes of the second locking ring 114, the first locking ring 113 and the base plate 101 in turn.

[0039] When using the friction wheel processing and forming tooling of this embodiment, after centering the wheel core 201 of different sizes, select the first locking ring 113 and the second locking ring 114 corresponding to the wheel core 201, and then put the first locking ring 113 and the second locking ring 114 together. At this time, the raised threaded holes of the first locking ring 113 and the second locking ring 114 will be aligned with the threaded holes of the bottom plate 101, and then let the locking bolt 115 be tightened in the threaded holes of the second locking ring 114, the first locking ring 113 and the bottom plate 101 in turn. , so that the first locking ring 113 and the second locking ring 114 are limited and fixed above the bottom plate 101, and then the first locking ring 113 will be tightly combined with the second locking ring 114. At this time, there is an annular space between the circular space formed by the first locking ring 113 and the second locking ring 114 and the pillow core, and then glue is applied to the annular space to obtain the glue layer 202, so that the glue layer 202 can protect the outer side of the wheel core 201. At the same time, the glue layer 202 can increase the friction at the contact point to improve the quality of the friction wheel.
