[0035] A horizontally slidable slider 8 is provided on the top of the device body 1, a mounting block 9 is fixed on the top of the slider 8, a mounting seat 10 is installed on the top of the mounting block 9, a clamping rod 11 is slidably connected inside the mounting seat 10, an adjustment mechanism 12 is provided at the end of the clamping rod 11 for adjusting the horizontal sliding of the clamping rod 11, and a hardware part body 13 is clamped in the middle of the clamping rod 11.
[0036] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a cylinder 31 is fixed on the top of the bracket 2, the output end of the cylinder 31 is connected to a piston rod 32, the bottom of the piston rod 32 is connected to the slide 3, a telescopic rod 33 is fixedly connected between the bracket 2 and the slide 3, and limit plates 34 are fixed at both ends of the slide 3.
[0037] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, two sides of the bracket 2 are provided with sliding grooves 21 for slidably connecting the limiting plate 34 .
[0038] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a support plate 81 is fixed to the surface of the device body 1, a second motor 82 is fixed to the end of the support plate 81, a screw rod 83 is fixedly connected to the output end of the second motor 82, the screw rod 83 is rotatably connected to the support plate 81, the mounting block 9 is threadedly sleeved with the screw rod 83, and a groove is provided on the top of the support plate 81 to facilitate the guiding sliding of the slider 8.
[0039] It should be noted that the slider 8 is threadedly connected to the screw rod 83. When the screw rod 83 rotates, the slider 8 that matches its thread will slide horizontally, and the slider 8 slides along the groove guide limit slide on the top of the support plate 81 to prevent the slider 8 screw rod 83 from turning and rotating.
[0040] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the adjustment mechanism 12 includes a third motor 1201 fixed inside the mounting block 9, the output end of the third motor 1201 is fixedly connected to a transmission rod 1202, a turntable 1203 is fixed to the top of the transmission rod 1202, an annular groove 1204 is provided on the surface of the turntable 1203, a convex rod 1205 is slidably connected inside the annular groove 1204, and a sliding rod 1206 is sleeved on the outside of the convex rod 1205.

[0042] It should be noted that there are three annular grooves 1204, which are evenly distributed on the surface of the turntable 1203, and the three annular grooves 1204 are interspersed with convex rods 1205, which slide inside. When the turntable 1203 rotates, the annular grooves 1204 are displaced, so that the three convex rods 1205 inside are forced to slide, thereby achieving the effect of a three-jaw chuck, and the third motor 1201 drives the transmission rod 1202 to expand when it rotates clockwise, and clamp it when it rotates counterclockwise.
[0043] It should be noted that the specific models and specifications of the first motor 5, the second motor 82, the third motor 1201 and the cylinder 31 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.
[0044] The use method and advantages of the utility model: When the device for adjusting the surface flatness of hardware parts is working, the working process is as follows:
[0045] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the uneven surface of the hardware parts is adjusted to be level, the third motor 1201 is started to drive the transmission rod 1202 to rotate clockwise and drive the turntable 1203 to rotate in the mounting seat 10. When the turntable 1203 rotates, the annular groove 1204 on the surface is displaced, and the convex rod 1205 inserted in the annular groove 1204 is forced to slide. While sliding, the sliding rod 1206 sleeved on the outside slides outward and expands. Then, the hardware parts to be adjusted are placed on the mounting seat 10, and the third motor 1201 is started to drive the transmission rod 1202 to rotate counterclockwise, thereby driving the turntable 1203 to rotate, so that the clamping rod 11 slides inward and fits on the surface of the hardware parts body 13 to clamp and fix it, so that the surface flatness of the hardware parts cannot shake or deviate during the rubbing adjustment process, thereby improving the adjustment quality.
[0046] The second motor 82 is started to drive the screw rod 83 to rotate. When the screw rod 83 rotates, the external sleeved slider 8 slides horizontally along the groove on the top of the mounting plate. At the same time, the mounting block 9 on the top of the slider 8 drives the clamped hardware part body 13 to move and adjust, so that it can be adjusted according to the required friction flattening position, thereby improving the flexibility of use;
[0047] The starting cylinder 31 drives the piston rod 32 to drive the slide plate 3 to slide down. When the slide plate 3 slides down, the telescopic rod 33 is stretched immediately. At the same time, the limit plates 34 at both ends of the slide plate 3 slide along the slide groove 21 of the bracket 2, so that the slide plate 3 drives the grinding roller 7 installed at the end through the connecting rod 4 to slide down and fit the surface of the hardware part. The first motor 5 is started to drive the rotating roller 6 to drive the grinding roller 7 to rub and smooth the uneven places on the surface of the hardware part body 13, thereby improving work efficiency.
[0048] The above shows and describes the basic principle, main features and advantages of the utility model.
