Description

Technical Field

[0001] This utility model relates to the field of carbon fiber frame polishing technology, and more specifically to an automated carbon fiber frame polishing device. Background Technology

[0002] Carbon fiber composites are widely used in many fields due to their excellent properties such as lightweight, high strength, corrosion resistance, and high temperature resistance. However, they face the following main challenges in grinding: carbon fiber composites are composed of resin matrix and carbon fiber layers, and the interlayer bonding force is relatively weak. Traditional rigid grinding tools can easily cause the carbon fiber layers to peel off or the resin matrix to overheat and carbonize.

[0003] Carbon fiber components typically have complex curved surfaces and thin-walled structures, making it difficult for traditional fixed grinding and polishing tools to adapt to surface undulations, resulting in uneven grinding or over-grinding.

[0004] With the development of industrial automation and the increase in labor costs, robot technology has been widely used in various fields. Polishing and grinding, as an important surface treatment process, has always required a lot of manual labor, which is inefficient and poses certain safety hazards. Utility Model Content

[0011] As a further embodiment of this utility model, the second positioning component includes a tapered pin hole disposed on the tooling plate b, the tapered pin hole being adapted to an aluminum boss at one end of the carbon fiber frame.

[0012] As a further embodiment of this invention, the second positioning component also includes a detection sensor disposed on the tooling plate a, for detecting whether the second end of the carbon fiber frame is in a preset installation position.

[0013] As a further embodiment of this utility model, a sensor bracket is provided on one side of the tooling plate a, and a detection sensor on the tooling plate a is fixed on the sensor bracket, and a sensor is also provided on the sensor bracket.

[0014] As a further embodiment of this utility model, the flipping shaft is provided with a horizontal plate, an active connecting plate and a driven connecting plate.

[0018] 3. The parting line of the carbon fiber frame of this utility model integrates an electric spindle with milling function onto a grinding robot. The electric spindle does not have a floating function, and its processing trajectory extends approximately 1mm around the perimeter of the frame product. After the electric spindle mills the parting line on the frame surface to be uniform, the floating grinding head then grinds the 1mm parting line. Because the parting line is basically uniform after milling, carbon fiber frames can be mass-produced. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] like Figure 7 The diagram shown is a schematic of the carbon fiber frame 58 requiring polishing according to an embodiment of this utility model. Before polishing, the carbon fiber frame 58, after thermoforming, has uneven parting lines and a relatively rough surface, therefore requiring polishing of the parting lines and the entire frame. The carbon fiber frame is an irregularly shaped elongated strip, with the parting lines located on its side along its length. The two ends along the length are defined as a first end and a second end. The first end has an aluminum boss after thermoforming, and the second end has a base surface 76 for connecting with other frames. After final polishing, the carbon fiber frame 58 appears as follows... Figure 8 As mentioned above, an aluminum sleeve 584 will be inlaid at its second end later.

[0023] Reference Figures 1-12 Based on the characteristics of the carbon fiber frame 58, this utility model provides an automated grinding equipment for carbon fiber frames, used for fixing and grinding the carbon fiber frame 58.

[0024] Depend on Figure 1 It is known that the base 4 of the automated grinding equipment for carbon fiber frames is equipped with a grinding robot 6 and a three-axis positioner 3. The three-axis positioner 3 includes two rotating axes 31 and a tooling fixture 5 is installed on the three-axis positioner 3.

[0025] The tooling fixture 5 includes a first tooling plate 55 used in the milling process and a second tooling plate used in the grinding process.

[0026] The two ends of the first tooling plate 55 in the length direction are respectively connected to the flipping shaft 31 of the three-axis positioner 3. The first tooling plate 55 is provided with a first positioning component and a first clamping component. The first positioning component is located at the first end of the length direction of the first tooling plate and is adapted to the first end of the carbon fiber frame 58. The first clamping component is located in the middle of the first tooling plate 55 and provides a accommodating space in the middle of the carbon fiber frame 58, so that the upper and lower surfaces of the carbon fiber frame 58 in the length direction are clamped and the parting line between the upper and lower surfaces is exposed.

[0027] The second tooling plate includes tooling plate a71 and tooling plate b72 used in conjunction. Tooling plate a71 and tooling plate b72 are respectively connected to one end of the flipping shaft 31 of the three-axis positioner 3. A second positioning component adapted to the first end of the carbon fiber frame 58 is provided on tooling plate b72. Second clamping components adapted to both ends of the carbon fiber frame 58 are respectively provided on tooling plate a71 and tooling plate b72, so that the carbon fiber frame 58 is fixed between tooling plate a71 and tooling plate b72.

[0028] With the above structure, the carbon fiber frame 58 is fixed by two different tooling plates corresponding to the three-axis positioner 3 and the milling fixture mechanism and the polishing fixture mechanism. The three-axis positioner 3 rotates the tooling fixture to drive the carbon fiber frame 58 to rotate in front of the polishing robot 6, so that the polishing robot 6 can process the carbon fiber frame 58. The flip axis 31 of the three-axis positioner 3 is driven by a servo motor and serves as the external axis control of the robot. When polishing is performed, its flip axis 31 and the polishing robot 6 work together to complete the polishing of the carbon fiber frame 58.

[0029] In this embodiment, the first tooling plate 55 is used to clamp the carbon fiber frame 58, ensuring stable clamping and fully exposing the parting line, which is beneficial for the grinding robot 6 to grind the parting line. Then, the second tooling plate is used to clamp the carbon fiber frame 58, which fully exposes the entire carbon fiber frame 58, facilitating further comprehensive grinding and polishing of the carbon fiber frame 58.

[0030] In some specific embodiments, the first clamping assembly includes a first horizontal clamp 52, which provides a clamping force above the middle of the surface of the first tooling plate 55 in the direction of the surface of the first tooling plate 55. A special clamping plate 53 is fixed to the side of the first horizontal clamp 52 facing the surface of the first tooling plate 55. The special clamping plate 53 is arranged at both ends along the length of the first tooling plate 55. An upper clamping block 57 is fixed to the side of the special clamping plate 53 facing the surface of the first tooling plate 55, and a lower clamping block 56 is fixed in the middle of the surface of the first tooling plate 55. The lower clamping block 56 and the upper clamping block 57 respectively fit the upper and lower V-shaped inclined surfaces 582 of the carbon fiber frame 58. The tooling fixture 5 uses the upper clamping block 57 and the lower clamping block 56. The interior of the two clamping blocks is designed according to the shape of the carbon fiber frame 58 and uses plastic materials such as nylon, which can better fit the carbon fiber frame 58 without damaging the carbon fiber frame 58. The upper clamping block 57 is connected to a special pressure plate 53. The special pressure plate 53 is made of metal materials such as carbon steel to ensure that the upper clamping block 57 is effectively pressed without large deformation.

[0031] In some embodiments, such as Figure 11 and Figure 12As shown, the first positioning component includes a front positioning plate 54 disposed on the first end plate surface in the length direction of the first tooling plate 55. The front positioning plate 54 is provided with a tapered pin hole 541, which is adapted to the aluminum boss 583 at the first end of the carbon fiber frame 58 to realize the positioning of the carbon fiber frame 58.

[0032] In some embodiments, the first positioning component further includes a detection sensor 51 disposed on the surface of the second end of the first tooling plate 55 along its length, for detecting whether the second end of the carbon fiber frame 58 is in a preset installation position. Figure 5a As shown, the detection sensor 51 can be a distance sensor. The detection sensor is positioned towards the second end of the carbon fiber frame 58. The second end of the carbon fiber frame 58 has a base surface 76 that is connected to other frames. When the carbon fiber frame 58 is installed in place on the first tooling plate 55, the base surface 76 is in a vertical state. The detection sensor is placed horizontally at the second end of the first tooling plate 55 and is located outside the base surface 76. The sensor detects whether it is in place by detecting the distance between itself and the base surface 76.

[0033] When the tooling fixture 5 is used for milling, the first tooling plate 55 is a single plate connected to the flipping shaft 31. When the tooling fixture is used for polishing, the tooling fixture 5 is changed to a second tooling plate, which includes tooling plate a71 and tooling plate b72, respectively providing support for both ends of the carbon fiber frame 58.

[0034] In some embodiments, such as Figure 6a and 6b As shown, the second positioning component includes a tapered pin hole 541 (the same as that on the front positioning plate 54) provided on the tooling plate b72. The tapered pin hole 541 is adapted to an aluminum boss 583 at one end of the carbon fiber frame 58, and positioning is formed by engaging the aluminum boss 583 in the tapered pin hole 541.

[0035] Both tooling plate a71 and tooling plate b72 are provided with second horizontal clamping clamps 73 as second clamping assemblies. The second horizontal clamping clamps 73 are respectively above tooling plate a71 and tooling plate b72 and provide clamping force in the direction of tooling plate a71 and tooling plate b72. Figure 6a The second horizontal clamp 73 at the first end of the carbon fiber frame 58 presses against the opposite side of the aluminum boss of the carbon fiber frame 58, and the second horizontal clamp at the second end of the carbon fiber frame 58 presses against the inner side of the base surface 76 of the carbon fiber frame 58.

[0036] In some preferred embodiments, a sensor bracket 74 is vertically provided on the tooling plate a71 outside the base surface 76, and a detection sensor 51 is also provided on the sensor bracket 74 facing the base surface 76 to detect whether the second end of the carbon fiber frame 58 is in a preset installation position.

[0037] In some preferred embodiments, the sensor bracket 74 is also provided with a nozzle 75, which is located below the detection sensor 51. When the base surface 76 is installed in place, the nozzle is aligned with the lower edge of the base surface 76. The nozzle 75 is connected to an air source. Since the dust generated during the grinding process is relatively large, the nozzle 75 is used to perform air jet dust removal on the detection sensor 51 at regular intervals or as needed.

[0038] like Figure 6a As shown, the two ends of the carbon fiber frame 58 are fixed and the whole frame is exposed. In this state, the polished surface can reach more than 85% of the entire carbon fiber frame 58.

[0039] In some specific embodiments, such as Figure 10 As shown, the flipping shaft 31 is provided with a horizontal plate 311, an active connecting plate 312, and a driven connecting plate 313. The horizontal plate 311, the active connecting plate 312, and the driven connecting plate 313 are connected by a triangular connecting plate 314 to form a frame. The driven connecting plate 313 is connected to a driven shaft 315 and a tail connecting block 316. The active connecting plate 312 is connected to a motor reducer and a head connecting block 317. The head connecting block 317 and the tail connecting block 316 are used to connect the tooling fixture 5, which can be achieved by bolt and nut connection.

[0040] To achieve integrated grinding and polishing processes, such as Figure 3 As shown, the grinding robot 6 has an electric spindle 62 fixed to it by a mounting base 63. The mounting base 63 also has a floating grinding head 61 fixed to it by a force controller 64. The floating grinding head 61 forms an axial floating grinding by force control.

[0041] like Figure 1 and Figure 2 As shown, this is the grinding base station applicable to this embodiment. The base station is based on the base 4, and the machine cover 1 is fixed on the base 4. The grinding robot 6, the robot control cabinet 8, and the automatic consumable replacement station 7 are all located inside the machine cover 1, and the dust collector 2 is located outside the machine cover 1.

[0042] The three-axis positioner 3 is fixed to the front side of the base 4. A fixed plate tooling fixture 5 is vertically fixed on the base 4 in front of the machine cover 1. The tooling fixture 5 is fixed on two rotating shafts 31 on the three-axis positioner 3. After clamping and fixing the carbon fiber frame 58, the tooling fixture 5 rotates to various angles to cooperate with the grinding robot 6 to achieve multi-angle grinding.

[0043] like Figure 1 and Figure 2 As shown, the three-axis positioner has two horizontal tilting axes 31 and one vertical rotating axis 32. A fixed baffle 34 is vertically fixed on the base 4 at the front end of the machine cover 4. The fixed baffle 34 has a straight upper edge, and a movable baffle 33 is fixed above it via the rotating axis 32. When the fixed baffle 34 and the movable baffle 33 are on the same plane, they cooperate with the machine cover 1 and the base 4 to enclose the grinding robot 6 in a working space. The two tilting axes 31 of the three-axis positioner 3 are respectively set on the two sides of the movable baffle 33, forming a dual-station configuration inside and outside the machine cover 1. This allows the loading and unloading time to overlap with the grinding working time, improving grinding efficiency.

[0044] like Figure 3 As shown, the grinding robot 6 is equipped with a floating grinding head 61 and an electric spindle 62. The electric spindle 62 mainly performs milling work on the parting line 581 of the carbon fiber frame 58. Because the parting line 581 of the carbon fiber frame 58 has high strength, the electric spindle 62 needs to follow a fixed trajectory of the carbon fiber frame 58 during milling. The burrs around the carbon fiber frame 58 are milled to a certain distance from the outline of the carbon fiber frame 58, approximately 1mm. The remaining 1mm width is then ground using the floating grinding head 61.

[0045] The dust collector 2 is connected to the hood 1 through a pipe. When the dust collector 2 is working, the inside of the hood 1 becomes a negative pressure state, which better prevents the dust from overflowing.

[0046] The grinding robot 6 can be configured with various grinding processes. After a certain number of grinding cycles, it goes to the automatic consumables replacement station 7 to replace the sandpaper and cutting tools. The automatic consumables replacement station 7 enables automatic tool replacement. It can also be replaced by a tool magazine and sandpaper combined automatic replacement station to achieve automatic replacement of sandpaper and cutting tools.

[0047] like Figure 5a and 5b As shown, the milling fixture mechanism mainly clamps the upper and lower surfaces of the carbon fiber frame 58, which can expose the parting line 581 of the carbon fiber frame 58 outside the fixture clamp, and can achieve milling and grinding of more than 80% of the flash and burrs.

[0048] like Figure 6a and 6b As shown, the polishing fixture mechanism clamps the two ends of the carbon fiber frame 58 respectively, with no baffle in the middle. With the help of the flipping shaft 31, the polishing and grinding operations on the upper and lower surfaces of the carbon fiber frame 58 can be realized.

[0049] In operation, the operator clamps the carbon fiber frame 58 onto the tooling fixture 5. The detection sensor 51, a capacitive sensor, detects the carbon fiber frame 58 and can detect non-metallic materials such as carbon fiber. The three-axis positioner 3 rotates horizontally 180°, moving the carbon fiber frame 58 into the grinding equipment. The grinding robot 6 grinds the carbon fiber frame 58 according to the grinding process. Outside the grinding equipment, the operator clamps the new carbon fiber frame 58 onto the aligned tooling fixture 5. After the carbon fiber frame 58 inside the equipment is ground, it rotates counterclockwise 180° to continue grinding the new carbon fiber frame 58. The operator completes the replacement of the old and new carbon fiber frames 58 outside the equipment.

[0050] Finally, it should be noted that, in the description of this application, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can refer to mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc., are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

[0051] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs. The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
