Referring to fig. 1 to 3, the utility model provides a processing tool of car head pipe, processing tool includes: the carbon fiber winding machine comprises two fixing heads 10 and a fixing rod 20 connected to the two fixing heads 10, wherein the outer side surfaces of the fixing heads 10 are used for winding carbon fiber coil materials; the carbon fiber coil stock is heated and melted, and a firm vehicle pipe is formed after cooling. The fixing rod 20 is disposed between the two fixing heads 10, and the fixing rod 20 is used for connecting to the middle region of the two fixing heads 10.

In the technical solution provided in this embodiment, the processing fixture includes two fixing heads 10 and a fixing rod 20 connected to the two fixing heads 10, and the fixing rod 20 is connected to the middle region of the two fixing heads 10. The fixing heads 10 are respectively arranged at two opposite sides, and the fixing heads 10 are connected through the fixing rods 20, and the connecting positions of the fixing rods 20 are the central positions of the fixing heads 10, so that the central positions of two ends of the formed head pipe can be ensured to be on the same straight line. Therefore, when the carbon fiber material is wound, the two ends of the head pipe can be prevented from being dislocated.

In the related technical field, a processing jig is not adopted in the prior method, the length of a head pipe is difficult to control finely when a carbon fiber material is wound, and if the length of the head pipe is too long, the head pipe is placed into a die for forming, carbon fiber is folded inwards, and the structure is influenced; on the contrary, the short tube causes material loss and also affects the structure, the processing jig using the lathe head tube is used for accurately limiting the winding length, so that the length of the coiled material of the lathe head tube can be well controlled, and the stability of the product structure is improved.

Further, the fixing head 10 and the fixing rod 20 are reusable, and in order to ensure the durability of the processing jig, the fixing head 10 and the fixing rod 20 may be made of metal, for example, an existing aluminum alloy or the like.

In an embodiment of the present application, the fixture is fixed for easy processing. The fixing rod 20 includes a rod body 210 and a threaded connection portion 220, the threaded connection portion 220 is disposed at one end of the rod body 210, the rod body 210 penetrates through one fixing head 10, and the threaded connection portion 220 is in threaded connection with the other fixing head 10. The central position of another fixed head 10 is provided with a threaded hole, after the rod body 210 is threaded through the fixed head 10, the threaded connection portion 220 is aligned with the threaded hole, and by rotating the rod body 210, the threaded connection portion 220 is fixed in the threaded hole, thereby completing the connection and fixation of the fixed head 10 and the rod body 210.

In an embodiment of the present application, in order to ensure a distance between the two fixing heads 10, the fixing rod 20 further includes a clamping plate 230, the clamping plate 230 is sleeved on one end of the rod body 210 far away from the threaded connection portion 220, the rod body 210 penetrates through one of the fixing heads 10, and the clamping plate 230 is clamped to the fixing head 10 penetrated through the rod body 210. Through the threaded hole and the threaded connection portion 220, another fixing head 10 has already been connected with the rod body 210, and when the processing jig is assembled, the two fixing heads 10 are prevented from approaching through the clamping plate 230, that is, the clamping plate 230 can limit the distance between the two fixing heads 10. The catch plate 230 may have a circular or square shape, and the catch plate 230 has a larger outer size than the through hole of the corresponding fixing head 10. The clamping plate 230 may be welded to the rod body 210, or the clamping plate 230 and the rod body 210 may be integrally formed.

In an embodiment of the present application, the assembly of the rod 210 and the fixing head 10 is more labor-saving. A through hole 240 is formed in one end, away from the threaded connection portion 220, of the rod body 210, and the through direction of the through hole 240 is along the radial direction of the rod body 210; the processing jig further includes a rotating rod, and when the two fixing heads 10 are fixed, the rotating rod is inserted into the through hole 240 to rotate the rod body 210. So can increase moment, the assembly personnel uses less strength just can rotate the body of rod 210, the equipment of the processing tool of being convenient for.

In an embodiment of the present application, after the carbon fiber roll is wound, the processing jig needs to be removed. The fixing head 10 and the head pipe are connected too tightly, and sometimes are difficult to remove. Therefore, the processing jig comprises a rubber sleeve 30, and the rubber sleeve 30 is sleeved on the outer side surface of the fixing head 10. The rubber sleeve 30 is soft, and the rubber sleeve 30 and the carbon fiber winding layer can be well separated by being sleeved on the fixing head 10. After winding the carbon fiber coil stock, not hard up fixed head 10, the air enters into between fixed head 10 and the gum cover 30 very easily, so avoid fixed head 10 and carbon fiber to roll up the connection of layer too closely, be convenient for accomplish the dismantlement to fixed head 10. In addition, the material of gum cover 30 is different with the material of carbon fiber winding layer, avoids the adhesion together. Specifically, the rubber sleeve is made of silica gel. Silicone may provide good separation between the layer of carbon fibre material and the retaining head 10.

In an embodiment of the present application, the fixing head 10 includes an insertion section 110 and a covering section 120 connected to the insertion section 110, a diameter of the covering section 120 is larger than a diameter of the insertion section 110, the processing fixture further includes a support tube 40, the insertion section 110 is inserted into the support tube 10, and the support tube 40 is made of a polyester material. Specifically, the support tube 40 is used for blowing and expanding, so that when the carbon fiber material is heated, the wound carbon fiber layer is supported and attached to the inner wall of the processing mold. The material of the support tube 40 is polyurethane (PU for short).

In an embodiment of the present application, the fixation head 10 further comprises a transition section 130, the transition section 130 extending from the cover section 120 to the insertion section 110, the diameter of the transition section 130 gradually decreasing from the cover section 120 to the insertion section 110. The transition section 130 reduces the angle between the cover section 120 and the insert section 110, thereby preventing the support tube 40 from being damaged.

In one embodiment of the present application, the fixing head 10 has a circular ring structure, i.e., the insertion section 110 and the covering section 120 are both circular ring-shaped. The channel configuration of the support tube 40 is circular, and this arrangement ensures that the internal channel configuration of the shaped support tube 40 is also circular.

The above is only the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all of which are in the utility model discloses a conceive, utilize the equivalent structure transform that the content of the specification and the attached drawings did, or directly/indirectly use all to include in other relevant technical fields the patent protection scope of the present invention.
