DETAILED DESCRIPTION

[0026] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0027] like Figure 1As shown, the metal surface processing device includes a base 1 and a driving mechanism 2 and a processing table 4 installed on the base 1. The driving mechanism 2 is installed with a grinder 3, and the metal part 9 to be processed is placed on the processing table 4. When the driving mechanism 2 is running, the grinder 3 is driven to move in an L-shaped trajectory. During the operation of the grinder 3, the surface of the metal part 9 on the processing table 4 is polished. When the driving mechanism 2 reciprocates, the polishing action also reciprocates accordingly.

[0028] Figure 2 A cross-sectional view of the driving mechanism 2 is shown, which includes a straight rail 21 parallel to the processing table 4, and the straight rail 21 includes an upper straight rail 21a and a lower straight rail 21b that are integrally formed, wherein the upper straight rail 21a is provided with an upper slider 23 that slides with it, and the lower straight rail 21b is provided with a lower slider 22 that slides with it, and the straight rail 21 limits the upper and lower sliders 22 from moving freely in the vertical direction. The upper slider 23 and the lower slider 22 are connected by at least two parallel connecting rods 24, the upper end of the connecting rod 24 is movably connected to the upper slider 23 by a pin, and the lower end of the connecting rod 24 is movably connected to the lower slider 22 by a pin, and the upper and lower sliders 22 are arranged in a front-to-back offset manner, and the bottom of the lower slider 22 is connected to the movable end of the electric push rod 26, and the direction in which the electric push rod 26 is arranged is parallel to the straight rail 21, and is used to drive the lower slider 22 to slide along the straight rail 21; the top of the upper slider 23 is connected to the support plate 25, and the grinding tool 3 is installed on the support plate 25. The grinding head of the grinding tool 3 extends toward the processing table 4, and a vertical baffle 27 is also provided at one end away from the upper straight rail 21a. The height of the vertical baffle 27 needs to be greater than the height of the vertical baffle 27. There is a distance between the vertical baffle 27 and the upper straight rail 21a, and the distance is not less than the length of the upper slider 23. It is particularly important to note that the connecting rod 24 is an adjustable telescopic rod, which is composed of a plurality of nested tubes connected together and locked with each other by a bead locking structure. After adjusting to an appropriate length, the bead is released and reset by a spring to lock it. The device changes the maximum height of the upper slider 23 by adjusting the length of the connecting rod 24, that is, changes the maximum height of the mold 3 at the same time. This structure can adapt to metal plates of different sizes.

[0029] The movement principle of the driving mechanism 2 is as follows: the electric push rod 26 is extended and retracted through the movable rod to drive the lower slider 22 to make a linear motion along the lower part of the straight rail 21. Synchronously, the upper slider 23 and the mold 3 installed on the top thereof are driven to make a linear motion along the upper part of the straight rail 21 through the connecting rod 24. Among them, the vertical baffle 27 is located on the movement path of the upper and lower sliders 22. The upper slider 23 first abuts against the vertical baffle 27, and the linear motion of the upper slider 23 is blocked. At the same time, the upper slider 23 is in the area between the vertical baffle 27 and the upper part of the straight rail 21. Under this area, the upper slider 23 is separated from the upper part of the straight rail 21, and the upper slider 23 is no longer restricted in the vertical direction and slides down. Since the block 22 is misaligned with the upper slider 23, there is still a distance between the lower slider 22 and the vertical baffle 27 at this time. The lower slider 22 continues to run toward the vertical baffle 27, so that the blocked upper slider 23 moves vertically along the vertical baffle 27 under the action of two movably connected connecting rods 24. After the lower slider 22 approaches the vertical baffle 27, the movement ends. Therefore, the support plate 25 connected to the top of the upper slider 23 and the mold 3 installed on the support plate 25 first make a linear motion in the horizontal direction, then turn and move vertically. The motion trajectory is L-shaped, and the entire stroke just drives the mold to complete the surface grinding of the metal part 9.

[0030] refer to Figure 1 The processing table 4 is a hollow rectangular box. The top surface of the processing table 4 is provided with an inlet 41 connected to the interior thereof, and the edge of the top surface is provided with a stop bar 44 protruding upward. A suction fan 42 is provided on the side of the processing table 4. The suction port of the suction fan 42 extends into the interior of the processing table 4. A negative pressure is formed inside the processing table 4 by suction, and the processed debris and dust are sucked into the box through the inlet 41. The outlet of the suction fan 42 is connected to a material box 43, and impurities are collected in the material box 43.

[0031] It should be noted that the processing area on the upper end surface of the processing table 4 can be set as a magnetic area. During the processing of the metal part 9, by setting some removable metal blocks on the processing table 4, the metal part 9 can be limited and fixed by the principle of magnetic attraction of the metal blocks, thereby reducing the deviation caused by contact or shaking during the processing.

[0032] refer to Figure 1 and Figure 4Furthermore, the vertical baffle 27 is adjustably connected to the lower straight rail 21b, and the vertical baffle 27 can be adjusted in position along the track direction of the straight rail 21, so as to adjust the relative distance between the vertical baffle 27 and the upper straight rail 21a. Specifically, a slide groove is formed on the lower straight rail 21b along its length direction, and a slider is embedded in the slide groove. One end of the slider is fixedly connected to the vertical baffle 27. A locking member is provided on the slider. After the slider is adjusted to a proper position, it is locked by the locking member. In a specific embodiment, the locking member is a screw. By appropriately adjusting the position of the vertical baffle 27, the displacement distance of the upper slider 23 in the horizontal direction can be adjusted, so as to adapt to metal parts 9 of different sizes.

[0033] In addition, a limit plate 61 is provided on the upper side of the processing table 4. The limit plate 61 is used to limit the position coordinates of the metal part 9 to be processed. The limit plate 61 is fixedly connected to the vertical baffle 27 through a connecting arm 6. When the position of the vertical baffle 27 is adjusted, the limit plate 61 is adjusted synchronously. Specifically, one end of the connecting arm 6 is provided with a plurality of horizontally penetrating holes, and the back of the limit plate 61 is provided with a plurality of pins 62 corresponding to the holes one by one. The end of the pin 62 is provided with a thread. The pin 62 is locked by a nut after passing through the hole. Second springs 63 are respectively sleeved on the pin 62, and the second springs 63 are located between the connecting arm 6 and the limit plate 61.

[0034] like Figure 3 As shown, in a preferred embodiment, it also includes a swing mechanism 5, which can make the grinding tool 3 swing back and forth in the axial direction of the rotating shaft, so as to achieve a good grinding or polishing effect. Specifically, it includes a slide plate 51 arranged on the upper side of the support plate 25, and the support plate 25 and the slide plate 51 are slidably connected, which can be connected in a manner similar to a slide rail slider. The upper end of the slide plate 51 is installed with the grinding tool 3, and the lower end of the slide plate 51 is provided with an abutment sheet 52 extending downward, and the abutment sheet 52 is provided with a plurality of sliding holes horizontally penetrating its surface, and a transverse sliding rod 53 is respectively provided in the sliding hole for sliding, and the transverse sliding rod 53 plays a guiding role, and its setting direction is consistent with the axial direction of the rotating shaft of the grinding tool 3, and the transverse sliding rod 53 is respectively sleeved with The first spring 54, one end of which is in contact with the abutment sheet 52 and the other end of which is in contact with the support plate 25, further comprises a motor 55 and a cam 56 mounted on the motor 55, the motor 55 being mounted on the support plate 25, the cam 56 being in contact with the abutment sheet 52, when the cam 56 rotates, the raised position squeezes the abutment sheet 52, causing it to slide along the horizontal slide bar 53 and compress the first spring 54, at this time, the abutment sheet 52 synchronously drives the slide plate 51 to slide along the support plate 25, when the raised position is away from the abutment sheet 52, the abutment sheet 52 moves in the opposite direction under the elastic force of the first spring 54, at this time the slide plate 51 also moves in the opposite direction, and the mold can be driven to swing back and forth through the swing mechanism 5, thereby improving the grinding or polishing effect.

[0035] This embodiment is basically the same as the above embodiment, except that the swing mechanism 5 of this embodiment uses a continuous ridge 7 and an abutment rod 71 instead of the above-mentioned motor 55 and cam 56. Specifically, the continuous ridge 7 includes a horizontal continuous ridge 7 arranged on one side of the processing table 4 and a vertical continuous ridge 7 arranged on one side of the limit plate 61. The abutment rod 71 is connected to one side of the abutment sheet 52. The continuous ridge 7 is located on the path of the abutment rod 71. The abutment rod 71 that moves synchronously with the abutment sheet 52 first touches the horizontal continuous ridge 7 and swings according to its concave and convex properties, thereby driving the abutment sheet 52 and the slide plate 51 to slide along the support plate 25, which also achieves the effect of swinging the mold 3. Similarly, when passing through the vertical continuous ridge 7, the swinging effect is the same.

[0036] The present invention is suitable for surface grinding, polishing and other treatments of the L-shaped metal piece 9. It not only has continuous actions but also good adaptability. In addition, the present invention has a compact structure and does not occupy space.
