Description

Technical Field

[0001] This utility model belongs to the field of bolt processing technology, and in particular relates to a carbon bolt grinding processing equipment. Background Technology

[0002] Carbon-carbon bolts are made of high-hardness carbon-carbon composite materials, making them difficult to manufacture. To ensure dimensional accuracy and surface quality, they require precision machining techniques such as grinding.

[0003] For example, in the prior art, the patent with authorized patent publication number CN220178946U discloses a processing equipment for slender carbon bolts. Although this patent can avoid the problem of low processing accuracy of the workpiece caused by the rapid wear of traditional turning tools, and at the same time, its grinding mechanism can effectively prevent the slender workpiece from bending when subjected to the axial force of the grinding wheel when the workpiece is supported by the support block in the positioning mechanism, the grinding wheel in this patent will be covered with chips during use, which may affect the processing accuracy. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a carbon-carbon bolt grinding equipment that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a carbon bolt grinding processing equipment, including a base plate; a vertical fixing plate fixedly connected to the top of the base plate, a chuck rotatably mounted on the vertical fixing plate; and a grinding unit disposed above the base plate; the grinding unit includes a mounting plate, a concave groove is formed on the mounting plate, a connecting shaft is rotatably mounted on the mounting plate, a grinding wheel rotating in the concave groove is fixedly connected to the connecting shaft, and a corresponding air blowing pipe is provided above the grinding wheel.

[0006] Preferably, a first driving unit is mounted on the vertical fixed plate, a T-shaped moving plate is fixedly connected to the output end of the first driving unit, a vertical extension plate is fixedly connected to the top of the T-shaped moving plate, a second driving unit is mounted on the vertical extension plate, and the output end of the second driving unit is fixedly connected to the mounting plate.

[0007] Preferably, a pair of limiting support rods are slidably connected to the T-shaped moving plate. One end of the limiting support rod is fixedly connected to the vertical fixed plate, and the other end of the limiting support rod is fixedly connected to a limiting block. The limiting block is fixedly connected to the top of the base plate.

[0008] Preferably, the bottom of the T-shaped movable plate is in contact with the top of the base plate.

[0009] Preferably, the concave groove is interconnected with multiple surfaces of the mounting plate, and the surface diameter of the grinding wheel is larger than the inner wall diameter of the concave groove.

[0010] Preferably, a third drive unit connected to one end of the connecting shaft is installed on one side of the mounting plate, and an air guide cylinder sleeved on the connecting shaft is fixedly connected to the other side of the mounting plate.

[0011] Preferably, the bottom end of the air inlet pipe is provided with a filter screen, and the air blowing pipe is a metal shaped tube.

[0012] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention, through the coordinated cooperation of the connecting shaft, air guide cylinder, blade, air inlet pipe and air blowing pipe, enables the grinding wheel to not only grind carbon bolts during rotation, but also to use the power of the grinding wheel rotation to draw in gas through the air guide cylinder and blow this gas onto the surface of the grinding wheel through the air blowing pipe.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0021] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0022] In the description of this utility model, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Reference Figures 1-5A carbon bolt grinding machine includes a base plate 1; a vertical fixed plate 2 fixedly connected to the top of the base plate 1, with a chuck 3 rotatably mounted on the vertical fixed plate 2; and a grinding unit disposed above the base plate 1. The grinding unit includes a mounting plate 4, a first drive unit 5 mounted on the vertical fixed plate 2, a T-shaped moving plate 51 fixedly connected to the output end of the first drive unit 5, a vertical extension plate 52 fixedly connected to the top of the T-shaped moving plate 51, a second drive unit 53 mounted on the vertical extension plate 52, the output end of the second drive unit 53 fixedly connected to the mounting plate 4, and a pair of limiting support rods 54 slidably connected to the T-shaped moving plate 51. One end of each limiting support rod 54 is fixedly connected to the vertical fixed plate 2, and the other end is fixedly connected to the vertical fixed plate 2. A limiting block 55 is fixedly connected to the top of the base plate 1. A concave groove 40 is provided on the mounting plate 4. A connecting shaft 41 is rotatably provided on the mounting plate 4. A grinding wheel 42 rotating in the concave groove 40 is fixedly connected to the connecting shaft 41. A corresponding air blowing pipe 43 is provided above the grinding wheel 42. A third drive unit 44 connected to one end of the connecting shaft 41 is installed on one side of the mounting plate 4. An air guide cylinder 45 sleeved on the connecting shaft 41 is fixedly connected to the other side of the mounting plate 4. Multiple blades 46 that fit against the inner wall of the air guide cylinder 45 are fixedly connected to the connecting shaft 41. An air inlet pipe 47 is connected to the lower surface of the air guide cylinder 45. The upper surface of the air guide cylinder 45 is connected to the corresponding end of the air blowing pipe 43.

[0024] When using the above technical solution, firstly, the carbon bolt to be processed is placed on the chuck 3 and clamped. The chuck 3 is rotated by a servo motor installed on the vertical fixing plate 2, so that the carbon bolt clamped in the chuck 3 can cooperate with the grinding wheel 42 for processing. Then, the second drive unit 53 using a cylinder is started to drive the grinding wheel 42 on the mounting plate 4 to contact the surface of the carbon bolt, and the third drive unit 44 using a servo motor is started to drive the connecting shaft 41 to rotate, thereby driving the grinding wheel 42 to grind the carbon bolt. When it is necessary to move the grinding wheel 42 along the surface of the carbon bolt for more comprehensive grinding, it is only necessary to start the first drive unit 5 using a cylinder to pull the T-shaped moving plate 51 to slide along the surface of the limiting support rod 54, so that the grinding wheel 42 can move and grind the surface of the carbon bolt.

[0025] It is worth mentioning that during the rotation of the connecting shaft 41, multiple blades 46 on the connecting shaft 41 will rotate along the inner wall of the air guide cylinder 45. These blades 46 draw in external gas through the air inlet pipe 47 and guide the gas to the air blowing pipe 43, and finally blow it from the air blowing pipe 43 to the surface of the grinding wheel 42. This design can effectively remove the debris adhering to the surface of the grinding wheel 42, thereby improving the grinding quality and efficiency of the grinding wheel 42 on the surface of the carbon bolt.

[0026] Additionally, it should be noted that the chuck 3 mentioned above uses a common three-jaw chuck structure. As for how to specifically fix the carbon bolts, this falls within the scope of existing technology and will not be elaborated here.

[0027] Furthermore, the bottom of the T-shaped moving plate 51 is in contact with the top of the base plate 1. This design can enhance the stability of the grinding wheel 42 during movement and ensure that the grinding wheel 42 can efficiently process carbon bolts.

[0028] Furthermore, the concave groove 40 is interconnected with multiple surfaces of the mounting plate 4, and the surface diameter of the grinding wheel 42 is larger than the inner wall diameter of the concave groove 40. This design is to ensure that the grinding wheel 42 can fully contact the carbon bolt when rotating, thereby effectively performing grinding.

[0029] Furthermore, the bottom end of the air inlet pipe 47 is equipped with a filter screen to reduce dust being drawn into the air guide tube 45, while the air blowing pipe 43 is a metal shaped tube, which allows the air outlet direction of the air blowing pipe 43 to be flexibly adjusted according to the actual situation of the debris on the surface of the grinding wheel 42.

[0030] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
