Description

Technical Field

[0001] This application relates to the technical field of carbon fiber tube processing equipment, and in particular to a carbon fiber tube thickness limiting device. Background Technology

[0002] When carbon fiber tubes are processed and formed, impregnated carbon fiber sheets are usually wound onto an inner tube. The wound inner tube and the carbon fiber sheets on its surface are then thermo-cured to form a carbon fiber tube. The formed carbon fiber tube is then removed from the inner tube, thus completing the processing of the inner tube.

[0003] However, after the carbon fiber sheet is wound onto the inner tube, it is difficult to ensure that the carbon fiber sheet and the inner tube fit tightly. This can result in gaps between some carbon fiber sheets and the inner tube, or excessive accumulation of carbon fiber sheets in certain positions of the inner tube. Consequently, the size of the carbon fiber tube produced later is larger than the required size, requiring the outer surface of the carbon fiber tube to be re-treated, thus reducing the production efficiency of the carbon fiber tube.

[0004] Therefore, a new technical solution is needed to address the above problems. Utility Model Content

[0005] In order to ensure that the carbon fiber sheet can be tightly attached to the surface of the inner tube before the carbon fiber tube is thermocured, this application provides a carbon fiber tube thickness limiting device.

[0010] By adopting the above technical scheme, the rolling direction of the inner pipe is guided by the guide assembly, so that the rolling direction of the inner pipe is kept moving with the reciprocating movement direction of the pressing plate, so that the carbon fiber sheet can be stably attached to the inner pipe.

[0017] Optionally, the sliding block is further provided with a plurality of elastic members, the elastic members are arranged on the upper and lower sides of the adjusting block respectively, and the elastic members all abut against the adjusting block.

DETAILED DESCRIPTION

[0029] The application will be further described in detail below with reference to the accompanying drawings.

[0030] The carbon fiber pipe thickness limiting device disclosed by the application, as shown in Figure 1 The workbench 1 is arranged on the ground, and the upper end surface thereof is horizontally arranged. The carbon fiber pipe to be processed is arranged on the upper end surface of the workbench 1. The pressing plate 2 is horizontally arranged, and the lower end of the pressing plate 2 is detachably connected with the contact plate 23. The contact plate 23 is replaced according to the length of the carbon fiber pipe. The pressing plate 2 is arranged higher than the upper end surface of the workbench 1. The pressing plate 2 is lowered and the contact plate 23 is abutted on the carbon fiber pipe, and the pressing plate 2 is horizontally reciprocated, so as to drive the carbon fiber pipe to roll synchronously with the inner pipe. In the rolling process, the carbon fiber sheet is tightly attached to the inner pipe, so that the carbon fiber pipe meeting the size requirement can be formed. The vertical driving member 22 is selected as an electric push cylinder in the embodiment. The cylinder body of the vertical driving member 22 is fixed on the mounting frame arranged on the workbench 1, and the piston rod of the vertical driving member 22 is fixed with a mounting plate. The horizontal driving member 21 is selected as a screw sliding table in the embodiment. The screw sliding table is arranged on the mounting plate. The upper end of the pressing plate 2 is slidably connected with the mounting plate. The driving end of the horizontal driving member 21 is fixed with the upper end of the pressing plate 2, so as to drive the pressing plate 2 to reciprocate.

[0031] As shown in Figure 2 In the rolling process of the inner pipe, it is difficult to control the positions of the two ends of the inner pipe, and the moving direction of the inner pipe is easily formed with an included angle with the moving direction of the pressing plate 2, which affects the rolling of the inner pipe. Therefore, the workbench 1 is further arranged with two groups of guiding assemblies 3 for guiding the moving direction of the carbon fiber pipe. The guiding assemblies 3 are arranged at the two ends of the inner pipe and connected with the inner pipe. The guiding assembly 3 comprises a sliding block 31 and an inner supporting member 32 connected with the sliding block 31. The sliding block 31 slides along the upper end surface of the workbench 1. The inner supporting member 32 rotates along the rotating direction of the inner pipe, and the inner supporting member 32 can be inserted into the inner pipe and abutted with the inner wall of the inner pipe. The inner supporting member 32 is connected with the inner pipe, so that the rolling direction of the inner pipe can be limited when the inner pipe rolls on the workbench 1. The rolling direction of the inner pipe is consistent with the moving direction of the pressing plate 2, so that the carbon fiber sheet can be pressed to tightly attach to the inner pipe.

[0032] The workbench 1 is also slidably provided with two groups of guide rods 4, which are parallel to the sliding direction of the sliding block 31. The two ends of the guide rod 4 are connected to the workbench 1 through a sliding block and a guide rail, and the sliding direction of the guide rod 4 is perpendicular to the length direction of the guide rod 4. Each group of guide rods 4 is arranged close to a sliding block 31, and the guide rod 4 is arranged in the sliding block 31 so that the sliding block 31 can move along the guide rod 4. When the inner tube is connected with the inner support 32, the guide rods 4 can be moved away from each other so that the inner support 32 can be conveniently inserted into the inner tube, and at the same time, the inner support 32 can be inserted into the inner tube of different lengths, so that the device can process carbon fiber tubes of different lengths.

[0033] The sliding block 31 is also vertically slidably provided with an adjusting block 33, and the inner support 32 is rotatably connected to the adjusting block 33, so that after the size of the carbon fiber tube to be processed changes, the inner support 32 can still be connected with the inner tube, and the outer wall of the carbon fiber tube can abut against the upper end face of the workbench 1. When the contact plate 23 contacts the carbon fiber tube, the lower end of the pressing plate 2 leaves a gap with the upper end of the adjusting block 33. The inner support 32 comprises a rotating part 321 and a supporting part 322 detachably connected to the rotating part 321. The rotating part 321 is rotatably connected to the end face of the adjusting block 33 away from the sliding block 31, and the end face of the rotating part 321 away from the adjusting block 33 is arranged in a regular octagon perpendicular to the rotating axis. The supporting part 322 is provided with an insertion slot 323 on the end face close to the rotating part 321, and the rotating part 321 is arranged in the insertion slot 323 and abuts against the inner wall of the insertion slot 323, so that the rotating part 321 can rotate synchronously with the supporting part 322, and after the size of the processed carbon fiber tube changes, the supporting part 322 of different sizes can be replaced to be connected with the inner tube of different sizes.

[0034] The sliding block 31 is respectively provided with two elastic members 34, which are selected as springs in this embodiment. The elastic members 34 are arranged at the upper and lower ends of the adjusting block 33, respectively. One end of the elastic member 34 is connected to the sliding block 31, and the other end of the elastic member 34 is connected to the adjusting block 33, so that the elastic member 34 applies an elastic force to the adjusting block 33. When the adjusting block 33 is not subjected to the downward pressure applied by the pressing plate 2, the position of the adjusting block 33 can be limited, so that a gap is left between the supporting part 322 and the upper end face of the workbench 1, and the inner tube is more easily connected with the supporting part 322.

[0035] Since the position of the guide rod 4 needs to be adjusted when connecting the inner tube with the support portions 322, the support portions 322 are moved away from each other, and then the inner tube is placed between the two support portions 322, and then the two support portions 322 are moved close to each other, and then the position of the guide rod 4 is limited. Therefore, the extension plate 41 is further fixed on the guide rod 4, the extension plate 41 is arranged on the side of the guide rod 4 away from the adjusting block 33, both ends of the extension plate 41 are fixedly installed with the end portions of the guide rod 4, and a gap is left between the extension plate 41 away from the end portions and the guide rod 4. The magnetic base 42 is installed in the middle of the side wall of the extension piece away from the guide rod 4, the lower end face of the magnetic base 42 abuts against the upper end of the workbench 1 and can be attracted to the workbench 1, so that the position of the guide rod 4 is limited by the magnetic base 42, the limiting of the guide rod 4 is more convenient, and the position of the limiting is closer to the middle of the guide rod 4, so that the stability of the guide rod 4 after the limiting is higher.

[0036] The implementation principle of the embodiment is that the knob of the rotating magnetic base 42 is rotated, the magnetic core base is no longer attracted to the workbench 1, then the guide rod 4 is moved to move the two support portions 322 away from each other, the inner tube with the carbon fiber sheet wound thereon is placed on the workbench 1 and one end of the inner tube is connected with one support portion 322, then the other support portion 322 is inserted into the inner tube by moving the guide rod 4, the knob of the rotating magnetic base 42 is rotated to attract the magnetic base 42 to the workbench 1. The vertical driving piece drives the pressing plate 2 to move downward until the contact plate 23 contacts the carbon fiber sheet on the inner tube and continues to move downward until the inner tube is pressed on the workbench 1, then the horizontal driving piece 21 drives the inner tube to roll on the workbench 1, so that the carbon fiber sheet is tightly attached to the inner tube to form a carbon fiber tube with a standard size, then the inner tube and the carbon fiber tube are taken down for heating and curing.

[0037] The embodiments of the specific embodiment are the preferred embodiments of the application, but do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
