[0124] Please see Figures 1-3 This application provides an automatic pressing device, including: a first pressing part 1, a second pressing part 2, a moving part 3 and a detection part 4;
[0125] The first pressing part 1 is used to clamp the first workpiece 5, and the first pressing part 1 is also used to adjust the position of the first workpiece 5 in the horizontal and vertical directions.
[0126] The second pressing part 2 is used to clamp the second workpiece 6;
[0127] The detection unit 4 is used to detect the horizontal distance between the first workpiece 5 and the second workpiece 6; the detection unit 4 is also used to detect the relative position of the first workpiece 5 and the second workpiece 6.
[0128] The moving part 3 is connected to the first pressing part 1. The moving part 3 is used to control the first pressing part 1 to move toward the second pressing part 2 according to the workpiece distance in the horizontal direction, so that the first workpiece 5 contacts the second workpiece 6.
[0129] The moving part 3 is also used to press the first workpiece 5 onto the second workpiece 6.
[0130] In this example, the first workpiece 5 is clamped by the first pressing part 1, the second workpiece 6 is clamped by the second pressing part 2, and the control detection part 4 detects the relative position of the first workpiece 5 and the second workpiece 6; wherein, the relative position represents the distance between the axis of the first workpiece 5 and the axis of the second workpiece 6 in the horizontal and vertical directions.
[0131] If the determined relative position is not within the pre-defined tolerance range, the first pressing part 1 is controlled to adjust the first workpiece 5 in the horizontal and / or vertical directions so that the relative position is within the tolerance range.
[0132] If the determined relative position is within the pre-defined tolerance range, the control detection unit 4 detects the horizontal workpiece distance between the first workpiece 5 and the second workpiece 6.
[0133] The control moving part 3 moves the first pressing part 1 according to the workpiece distance, so that the first workpiece 5 comes into contact with the second workpiece 6; the control moving part 3 moves the pressing distance, so that the first pressing part 1 presses the first workpiece 5 onto the second workpiece 6, thereby realizing the technical effect of automatic pressing of the first workpiece 5 and the second workpiece 6 and improving the pressing efficiency of the workpiece.
[0134] Meanwhile, the position of the first workpiece 5 can be adjusted in the horizontal and vertical directions through the first pressing part 1, and the relative position of the first workpiece 5 and the second workpiece 6 can be detected by the detection part 4. After ensuring that the first workpiece 5 and the second workpiece 6 are aligned, the first workpiece 5 and the second workpiece 6 are pressed, thus realizing the pressing of different models of the first workpiece 5 and the second workpiece 6 and expanding the application range of workpiece pressing.
[0135] In a preferred embodiment, the first pressing part 1 includes: a support frame 11, a clamping mechanism 12, a floating mechanism 13, and a positioning mechanism 14;
[0136] Clamping mechanism 12 is used to clamp the first workpiece 5;
[0137] The floating mechanism 13 is connected to the clamping mechanism 12, and the floating mechanism 13 is used to adjust the position of the clamping mechanism 12 in the vertical direction;
[0138] The positioning mechanism 14 is connected to the floating mechanism 13 and is fixed on the support frame 11. The positioning mechanism 14 is used to adjust the position of the clamping mechanism 12 in the horizontal and vertical directions.
[0139] In this example, the first workpiece 5 is clamped by the clamping mechanism 12, and the position of the clamping mechanism 12 and the first workpiece 5 is adjusted in the horizontal and vertical directions by the positioning mechanism 14.
[0140] When the first workpiece 5 and the second workpiece 6 are fitted with a clearance fit, the relative positions of each set of the first workpiece 5 and the second workpiece 6 may be inconsistent. The axes of some sets of the first workpiece 5 and the second workpiece 6 are on the same straight line, while the axes of some sets of the first workpiece 5 and the second workpiece 6 are not on the same straight line. Therefore, the floating mechanism 13 can be used to make fine adjustments between the first workpiece 5 and the second workpiece 6. This ensures that even if the first workpiece 5 and the second workpiece 6 are not on the same straight line, they can still be aligned after the fine adjustment of the floating mechanism 13, and the first workpiece 5 can be pressed onto the second workpiece 6. Therefore, the tolerance range of the relative position between the first workpiece 5 and the second workpiece 6 is expanded, and the pressing efficiency of the first workpiece 5 and the second workpiece 6 is improved.
[0141] Furthermore, the first workpiece 5 includes a first body 51, an upper protrusion 52 and a lower protrusion 53, with the upper protrusion 52 and the lower protrusion 53 respectively fixed on the side of one side of the first body 51;
[0142] The clamping mechanism 12 includes: a clamping plate 121, an upper positioning block 122, a lower positioning block 123, a support block 124, a clamping rail 125, a clamping slider 126, a clamping block 127, a connecting plate 128, and a clamping cylinder 129.

The lower positioning block 123 is used to support the lower protrusion 53.
[0145] The support block 124 is fixed on the surface of the clamping plate 121 on the side with the upper positioning block 122. The support block 124 contacts the side of the upper protrusion 52 or the lower protrusion 53 away from the first body 51. The support block 124 is used to support the upper protrusion 52 or the lower protrusion 53. A plurality of support blocks 124 are arranged on the clamping plate 121. The plurality of support blocks 124 are used to support the upper protrusion 52 and the lower protrusion 53.
[0146] The clamping rail 125 is fixed on the surface of the clamping plate 121 on the side with the upper positioning block 122. The clamping slider 126 is slidably connected to the clamping rail 125. The clamping block 127 is fixed on the clamping slider 126. The clamping block 127 is used to contact the upper side of the upper protrusion 52 and cooperate with the upper positioning block 122 to clamp the upper protrusion 52.
[0147] One end of the connecting plate 128 is connected to the clamping block 127, and the clamping cylinder 129 is connected to the other end of the connecting plate 128. The clamping cylinder 129 is used to control the clamping block 127 to move toward the upper protrusion 52, and the clamping cylinder 129 is also used to control the clamping block 127 to move away from the upper protrusion 52.
[0148] In this example, the first body 51 is the part of the first workpiece 5 used to press onto the second workpiece 6. The first workpiece 5 is supported by the upper positioning block 122 and the lower positioning block 123. The clamping cylinder 129 controls the clamping block 127, which, in conjunction with the upper positioning block 122, clamps the upper protrusion 52 of the first workpiece 5 to fix the first workpiece 5 on the clamping mechanism 12.
[0149] By setting the support block 124, the first workpiece 5 is supported during the pressing process onto the second workpiece 6, ensuring that the first workpiece 5 has sufficient supporting force to press onto the second workpiece 6.
[0150] Furthermore, the floating mechanism 13 includes: a floating plate 131, a floating support 132, a floating track 133, a floating slider 134, a floating lead screw 135, a floating moving block 136, a floating mounting base 137, a floating spring 138, and a floating pin 139;

[0152] The floating slider 134 is movably connected to the floating track 133. The floating slider 134 is connected to the clamping plate 121 of the clamping mechanism 12. The floating slider 134 is connected to the side surface of the clamping plate 121 away from the upper positioning block 122 of the clamping mechanism 12.
[0153] The floating lead screw 135 is fixed on the floating plate 131. The floating lead screw 135 is connected to the floating moving block 136. The floating moving block 136 is also connected to the clamping plate 121 of the clamping mechanism 12. The floating lead screw 135 controls the clamping mechanism 12 to move vertically along the floating track 133 through the floating moving block 136.
[0154] The floating mounting base 137 is fixed on the surface of the floating plate 131 facing the floating support 132. The floating mounting base 137 has a floating through hole 1310 that connects the upper and lower surfaces of the floating mounting base 137. The floating spring 138 is disposed in the floating through hole 1310. One end of the floating pin 139 passes through the floating spring 138 and contacts the bottom side of the clamping plate 121 of the clamping mechanism 12. The floating pin 139 and the floating spring 138 are fixed to each other. The floating spring 138 is used to prevent the floating pin 139 from moving in the vertical direction.
[0155] In this example, by setting a floating screw 135, the floating plate 131 can move on the floating track 133, thereby driving the clamping mechanism 12 to make fine adjustments in the vertical direction. By setting a floating pin 139 to support the clamping mechanism 12, and by setting a floating spring 138, the clamping mechanism 12 can float within the elastic range of the floating spring 138, which expands the allowable tolerance of the relative position. It eliminates the need to perform precise alignment of the axes of the first workpiece 5 and the second workpiece 6 before pressing the first workpiece 5, thus improving the pressing efficiency of pressing the first workpiece 5 onto the second workpiece 6.
[0156] Furthermore, the positioning mechanism 14 includes: a vertical positioning track 141, a vertical slider 142, a vertical lead screw 143, a horizontal positioning track 144, a horizontal slider 145, a horizontal lead screw 146, and a positioning plate 147;
