DETAILED DESCRIPTION

[0029] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0030] See Figures 1-6 , the utility model provides a technical solution:

[0031] Example:

[0032] like Figures 1-6 As shown, a high-precision automatic scraping machine includes a frame 1, a scraping mechanism 2 arranged on the frame 1, a high-point scanner 6 and a rotatable clamp 3;

[0033] The clamp 3 is used to fix the workpiece. The clamp 3 is set on the frame 1 through a first displacement mechanism 4. The first displacement mechanism 4 is used to drive the clamp 3 to move along the length direction or width direction of the frame 1;

[0034] The high point scanner 6 is used to scan the high points of the workpiece;

[0035] The scraping mechanism 2 is used to scrape the workpiece according to the high points scanned by the high point scanner 6. The scraping mechanism 2 is set on the frame 1 through the second displacement mechanism 5. The second displacement mechanism 5 is used to drive the scraping mechanism 2 to move vertically towards or away from the clamp 3.

[0036] 1. The high point scanner 6 is a prior art, and its specific structure and working principle are not described here. 2. The scraping mechanism 2 is located on the wide side of the frame 1, and the high point scanner 6 is located on the long side of the frame 1 and is away from the scraping mechanism 2.

[0037] The scraping mechanism 2 includes a scraping tool 7 and a crank-connecting rod assembly 8. The crank-connecting rod assembly 8 is arranged on a connecting arm 9, and the connecting arm 9 is connected to the second displacement mechanism 5.

[0038] like Figure 5 and Figure 6 As shown, the scraping tool 7 is connected to the crank connecting rod assembly 8 in a transmission manner. Figure 6 As shown, the crank is connected to the scraping tool through the first connecting rod and the second connecting rod, wherein one end of the first connecting rod is connected to the middle of the scraping tool, and the other end of the first connecting rod is connected to the motor ( Figure 6 The position marked with a cross dotted line is the position of the output shaft of the motor) and a rocker 20 is connected to the output shaft of the motor. Figure 1 As shown, the crank is connected to an end of the connecting arm away from the second displacement mechanism.

[0039] The second connecting rod is connected to the end of the scraping tool, and the middle part of the second connecting rod is connected to the crank ( Figure 6 The motor drives the rocker to rotate, and the rocker drives the second connecting rod to rotate around the connecting axis with the crank through the slot. In this process, the scraping tool is formed under the action of the first connecting rod and the second connecting rod. Figure 4 The scraping trajectory shown.

[0040] The clamp 3 is a multi-jaw chuck (a four-jaw chuck in this embodiment).

[0041] like Figure 1 As shown, the first displacement mechanism 4 includes a first linear guide 10 and a second linear guide 11 arranged horizontally. The first linear guide 10 is arranged along the length direction of the frame 1, and the second linear guide 11 is arranged on the first linear guide 10 and along the width direction of the frame 1. (Wherein, 1. The linear guide is a prior art, which includes a lead screw, a limit rod, and a slider that cooperates with the lead screw. The specific structure and principle are prior art and will not be described here in detail; 2. The first linear guide 10 is fixed to the frame 1, and the second linear guide 11 is installed on the slider of the first linear guide 10. When the first linear guide 10 is in operation, it drives the second linear guide 11 and the clamp 3 to move along the length direction of the frame 1 (i.e., the Y direction). When the second linear guide 11 moves, it drives the clamp 3 to move along the width direction of the frame 1 (i.e., the X direction))

[0042] The second displacement mechanism 5 includes a vertically disposed third linear guide rail. The connecting arm 9 is a U-shaped structure, one end of which is in driving connection with the third linear guide rail. (Specifically, one end of the connecting arm 9 is fixed to the slider of the third linear guide rail. When the third linear guide rail is in operation, the slider drives the connecting arm 9 to move vertically.)

[0043] like Figure 1 and Figure 2 As shown, it also includes two vertically arranged brackets 12, and the brackets 12 are provided with waist-shaped sliding grooves 13;

[0044] A rib plate is provided on the side wall of the connecting arm 9 , and a roller 14 adapted to the sliding groove 13 is provided on the rib plate.

[0045] The frame 1 is provided with two rails 15 parallel to the first linear guide rail 10 , and the first linear guide rail 10 is located between the two rails 15 ;

[0046] A slide rail 16 is slidably provided on the track 15 , and the second linear guide rail 11 is arranged on the slide rail 16 .

[0047] like Figure 1 and Figure 3 As shown, mounting portions 17 with an inverted concave structure are provided at both ends of the slide rail 16. Within the mounting portions 17 are vertical wheels 18 that engage with the top surface of the track 15, and side wheels 19 that engage with the side surfaces of the track 15. The mounting portions 17 are slidably connected to the slide rail 16 via the vertical wheels 18 and side wheels 19. The vertical wheels 18 are used to support the slide rail 16, while the side wheels 19 are used to limit and guide the slide rail 16 to prevent it from moving in the aforementioned X-direction.

[0048] Among them, 1. The signal output end of the high point scanner 6 is connected to the signal input end of the computer, and the signal output end of the computer is connected to the signal input end of the first displacement mechanism 4 and the signal input end of the second displacement mechanism 5 respectively. 2. Figure 4 In the figure, the arc circle at the end of the scraping tool is the motion trajectory of the scraping tool, which is the ideal scraping trajectory.

[0049] Working principle: The workpiece is clamped on the fixture 3, and the high-point scanner 6 is started; then the workpiece on the fixture 3 is moved and rotated in the X and Y directions respectively through the first linear guide 10 and the second linear guide 11. During the above-mentioned movement process, the high-point scanner 6 scans the high point of the workpiece and records it.

[0050] After the scan is completed, the first displacement mechanism 4 is started to drive the workpiece (where the high point is located) into the scraping range of the scraping tool 7, and then the second displacement mechanism 5 is started to make the scraping tool 7 close to the workpiece, and then the scraping tool 7 is started to scrape the high point.

[0051] The utility model can accurately identify the high points of the workpiece and perform precise scraping and grinding on the high points of the workpiece. By replacing manual labor with machinery, the scraping and grinding machine has a high degree of automation and can effectively solve the problems of high technical requirements and occupational diseases in manual scraping.

[0052] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the concept described herein through the above teachings or techniques or knowledge in the relevant fields. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
