Description

Technical Field

[0001] The invention belongs to the technical field of grinding devices, and more specifically, particularly relates to a positioning grinding device for a carbon fiber tube. Background Art

[0002] Carbon fiber tube, also known as carbon fiber tube, is made of carbon fiber composite material pre-impregnated with styrene-based polyester resin and then heated, cured, and pultruded (wrapped). During the manufacturing process, various profiles can be produced through different molds. During the processing of carbon fiber tube, it needs to be polished, so a polishing device is needed.

[0003] When grinding a carbon fiber tube, the existing grinding device needs to place the carbon fiber tube on two placement rollers, and then adjust the grinding wheel to contact the carbon fiber tube for grinding through an electric cylinder. However, when the electric cylinder for adjusting the grinding wheel is damaged, the grinding of the carbon fiber tube cannot be achieved. In the existing device, if the worker contacts the grinding wheel during grinding, it may cause injury, and protection cannot be achieved through structural improvements such as setting a baffle, and the baffle cannot be used to achieve rapid adjustment of the placement rollers. Although the existing device is provided with a positioning guide structure, it cannot achieve bending detection of the carbon fiber tube. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a positioning and grinding device for a carbon fiber tube to solve the problem that when the electric cylinder for adjusting the grinding wheel is damaged, the carbon fiber tube cannot be ground. If the staff comes into contact with the grinding wheel during grinding, they may be injured. Although a positioning guide structure is provided, it cannot realize the bending detection of the carbon fiber tube.

[0005] The purpose and effect of the positioning and polishing device for a carbon fiber tube of the present invention are achieved by the following specific technical means: A positioning and polishing device for a carbon fiber tube comprises a base; a placement component is installed on the base.

Two mounting blocks are fixed on the left side and the right side of the top surface of the base. A guide rod A is welded between the two mounting blocks on the left side, and a guide rod A is also welded between the two mounting blocks on the right side. Two mounting blocks slide on the two guide rods A, and a placement roller rotates on each mounting block. A pipe fitting is placed between the two placement rollers. A first motor is fixed on a mounting block on the rear side, and the output shaft of the first motor is fixed on a placement roller on the rear side; an adjusting rod rotates on the two connecting blocks on the left side, and an adjusting rod also rotates on the two connecting blocks on the right side. The front and rear ends of the two adjusting rods are respectively threadedly connected to the two mounting blocks, and the front and rear ends of the two adjusting rods are in opposite directions, and the threads on the two adjusting rods are in opposite directions.

[0007] Furthermore, a gear is welded on the front side of the outer wall of each adjusting rod; a baffle is plugged into the base, the baffle is a T-shaped plate structure, and the baffle is located on the front side of the pipe.

[0008] Furthermore, the left and right end surfaces of the baffle are provided with meshing teeth, which mesh with two gears respectively; a first electric cylinder is fixed to the top surface of the base, and the protruding end of the first electric cylinder is fixed to the baffle.

[0009] Furthermore, a grinding assembly is installed on the base, and the grinding assembly consists of a guide rod B, a mounting arm, a second electric cylinder, a first base body, a grinding wheel, a second motor, a second base body, a limiting wheel, a third motor and a limiting groove. Two guide rods B are fixed to the top surface of the base, and a mounting arm is slid on the two guide rods B. A second electric cylinder is fixed to the rear side of the top surface of the base, and the protruding end of the second electric cylinder is fixed to the bottom end surface of the mounting arm.

[0010] Furthermore, a first seat body is fixed to the bottom end surface of the mounting arm, a grinding wheel rotates on the first seat body, and a second motor for driving the grinding wheel to rotate is fixed to the first seat body; two second seat bodies are fixed to the bottom end surface of the mounting arm, a limiting wheel rotates on each second seat body, and a third motor for driving the limiting wheel is fixed to each second seat body.

[0011] Furthermore, each of the limiting wheels is provided with a limiting groove, and both limiting grooves are located above the pipe fitting. When the grinding wheel contacts the pipe fitting, the limiting groove contacts the outer wall of the pipe fitting.

[0012] Furthermore, an auxiliary component is installed on the base, and the auxiliary component consists of a third electric cylinder, a first mounting seat, a limit block, a scale and a circular hole. Four third electric cylinders are fixed on the top surface of the base, and the protruding ends of the two third electric cylinders on the left are fixed on the bottom surface of the first mounting seat, and the protruding ends of the two third electric cylinders on the right are fixed on the bottom surface of another first mounting seat.

At this time, the first electric cylinder is controlled to extend, and the first electric cylinder drives the baffle to rotate. When the baffle moves upward, it drives the two gears to rotate in the opposite direction. The two gears drive the two adjustment rods to rotate. When the adjusting rods rotate, the two mounting blocks move inward at the same time. At this time, the distance between the two placement rollers is reduced. After the distance between the two placement rollers is reduced, the pipe fitting can be squeezed upward until it contacts the grinding wheel. On the other hand, the baffle can be used to protect personnel and prevent injuries caused by contact between personnel and the grinding wheel. Compared with the existing device, the present application can realize emergency adjustment of the height of the pipe fitting when the second electric cylinder is damaged, and the emergency adjustment structure can also play a safety role.

[0017] In the present application, through the setting of auxiliary components, on the one hand, since the inner diameter of the circular hole is equal to the outer diameter of the pipe fitting, during processing, the pipe fitting is passed through the two circular holes on the right and continued to be pushed to the right. At this time, the two circular holes can be used to clean the debris on the outside of the pipe fitting; on the other hand, the pipe fitting is inserted into the two circular holes, the two third electric cylinders on the left are controlled to retract, and then the two third electric cylinders on the right are controlled to retract. Under the action of the two first mounting seats and the two limit blocks, the bending detection of the pipe fitting can be realized. Compared with the existing device, the present device can realize both the cleaning and the bending detection of the pipe fitting through the auxiliary components, and has strong functionality.

[0018] In the present application, through the setting of the grinding component, on the one hand, the pipe can be transported through the two limiting wheels, and on the other hand, the pipe can be limited through the limiting grooves on the two limiting wheels, thereby preventing the pipe from being separated from the placement roller during the grinding process.
