Referring to fig. 1 and 2, a mobile phone middle frame is specifically taken as an example to perform a pressing process. The pressing fixture 10 includes a base plate 100 and a cover plate assembly 300, the base plate 100 has a supporting surface 110 for carrying the workpiece 20, i.e. the workpiece 20 is placed on the supporting surface 110, and the cover plate assembly 300 presses on the surface of the workpiece 20, so as to cooperate with the base plate 100 to realize the pressing of the workpiece 20.
Specifically, the cover plate assembly 300 includes a first pressing plate 310 and a second pressing plate 320, and the second pressing plate 320 is connected to a side of the first pressing plate 310 facing away from the supporting surface 110 and can slide relative to the first pressing plate 310 along a direction perpendicular to the supporting surface 110. The first pressing plate 310 has a plurality of first pressing blocks 311 capable of pressing against the workpiece 20, and the second pressing plate 320 has a plurality of second pressing blocks 321 capable of pressing against the workpiece 20; when the sides of the plurality of first pressing pieces 311 and the plurality of second pressing pieces 321 facing the supporting surface 110 are coplanar, the first pressing plate 310 and the second pressing plate 320 have a gap in a direction perpendicular to the supporting surface 110. When the workpiece 20 is pressed, if the workpiece 20 is not attached to the supporting surface 110 and is suspended, because the first pressing plate 310 and the second pressing plate 320 have a gap in the direction perpendicular to the supporting surface 110, a movable space exists between the first pressing plate 310 and the second pressing plate 320 in the direction perpendicular to the supporting surface 110, and when a pressing force is applied to the supporting surface 110, the first pressing plate 310 and the second pressing plate 320 can slide relatively in the direction perpendicular to the supporting surface 110, so that the first pressing block 311 and the second pressing block 321 do not interfere with each other to independently press corresponding positions on the workpiece 20, and therefore, the pressing requirements of corresponding positions on the workpiece 20 are met. Therefore, the pressing jig 10 adopts a multi-point non-interference pressing manner, and the workpiece 20 can be seamlessly pressed on the supporting surface 110 under the condition that the plurality of first pressing blocks 311 and the plurality of second pressing blocks 321 are matched, so that the processing stability of the workpiece in the subsequent processing process is effectively ensured, and the product quality is improved. Specifically, when the sides of the plurality of first pressing blocks 311 and the plurality of second pressing blocks 321 facing the supporting surface 110 are coplanar, the gap between the first pressing plate 310 and the second pressing plate 320 in the direction perpendicular to the supporting surface 110 is 0.30-0.45 mm.
In one embodiment, the first pressing plate 310 includes a first connection portion 312 and three first pressing blocks 311, and the three first pressing blocks 311 are connected to the first connection portion 312 at intervals, so that the first pressing plate 310 has a "T" shape. Specifically, the first connection portion 312 is in an elongated shape, one end of the first connection portion 312 is connected to a first pressing block 311, and two sides of the other end are connected to the first pressing block 311, so that the first connection portion 312 and the three first pressing blocks 311 together form a "T" shaped first pressing plate 310.
The second pressing plate 320 includes a second connecting portion 322 and three second pressing blocks 321, and the three second pressing blocks 321 are connected to the second connecting portion 322 at intervals, so that the second pressing plate 320 is in a T-shaped structure. Specifically, the second connecting portion 322 is in a long strip shape, one end of the second connecting portion 322 is connected to one second pressing block 321, and two sides of the other end of the second connecting portion 322 are respectively connected to one second pressing block 321, so that the second connecting portion 322 and the three second pressing blocks 321 jointly form a "T" shaped second pressing plate 320.
The first pressing plate 310 and the second pressing plate 320 are connected by the first connection portion 312 and the second connection portion 322, that is, the cover plate assembly 300 includes a first connection member 330, and the first connection member 330 connects the first connection portion 312 and the second connection portion 322, so that the first pressing plate 310 and the second pressing plate 320 are connected together. Specifically, the first connecting member 330 is a pin, the first connecting member 330 penetrates through the first connecting portion 312 and the second connecting portion 322 along a direction perpendicular to the supporting surface 110, and at least the second connecting portion 322 can slide relative to the first connecting member 330 along an axial direction of the first connecting member 330. Further, there are two first connecting members 330, and the two first connecting members 330 are disposed at an interval, so as to achieve accurate connection between the first pressing plate 310 and the second pressing plate 320, and simultaneously prevent the second pressing plate 320 and the first pressing plate 310 from rotating relative to each other by using the axial direction of the first connecting members 330 as a rotating axis.
The first pressing plate 310 is disposed opposite to the second pressing plate 320. Because the first pressing plate 310 and the second pressing plate 320 are both of a "T" shaped structure, one end of the first connecting portion 312, which is provided with one first pressing block 311, and one end of the second connecting portion 322, which is provided with two second pressing blocks 321, are located at one side of the first connecting member 330, and one end of the first connecting portion 312, which is provided with two first pressing blocks 311, and one end of the second connecting portion 322, which is provided with one second pressing block 321, are located at the other side of the first connecting member 330, so that the pressing point positions with the same number on the two opposite sides of the first connecting member 330 can be kept to abut against the workpiece 20.
The first pressing pieces 311 and the second pressing pieces 321 are alternately arranged along the circumferential direction of the workpiece 20. On one side of the first connecting member 330, the first pressing block 311 is located between the two second pressing blocks 321, on the other side of the first connecting member 330, the second pressing block 321 is located between the two first pressing blocks 311, so that the three first pressing blocks 311 and the three second pressing blocks 321 are alternately arranged along the circumferential direction of the workpiece 20, and thus the situation that the workpiece 20 cannot be attached to the supporting surface 110 due to the fact that the region between the two adjacent first pressing blocks 311 lacks the pressing effect of the second pressing blocks 321 can be avoided, or the situation that the workpiece 20 cannot be attached to the supporting surface 110 due to the fact that the region between the two adjacent second pressing blocks 321 lacks the pressing effect of the first pressing blocks 311 can be avoided, and therefore the pressing requirements of multiple points on the workpiece 20 are met.
In addition, it should be noted that the first pressing plate 310 and the second pressing plate 320 are not limited to the "T" shaped structure, and in other embodiments, the first pressing plate 310 and the second pressing plate 320 may be in other shapes such as "Y" shape, "V" shape, etc. which can be changed according to the specific shape of the workpiece 20.
In one embodiment, two first pressing pieces 311 protrude from the side of the first connecting portion 312 facing away from the supporting surface 110 to form a first slot 313 capable of receiving the second connecting portion 322, and two second pressing pieces 321 protrude from the side of the second connecting portion 322 facing the supporting surface 110 to form a second slot 323 capable of receiving the first connecting portion 312. Specifically, at one end of the first connection portion 312, the two first pressing blocks 311 protrude from the first connection portion 312 to a side away from the supporting surface 110, so that a first slot 313 is formed between the two first pressing blocks 311, the second connection portion 322 can be just placed in the first slot 313, the first slot 313 can limit the position of the second connection portion 322, similarly, at one end of the second connection portion 322, the two second pressing blocks 321 protrude from the second connection portion 322 to the supporting surface 110 side, so that a second slot 323 is formed between the two second pressing blocks 321, the first connection portion 312 can be just placed in the second slot 323, and the second slot 323 can limit the position of the first connection portion 312, so that the first connection portion 312 and the second connection portion 322 can only relatively slide in a direction perpendicular to the supporting surface 110, and cannot relatively rotate. Further, such an arrangement also reduces the occupied space of the cover plate assembly 300 along the direction perpendicular to the supporting surface 110, so that the overall structure is more compact.
In one embodiment, the cover plate assembly 300 includes a third pressing plate 340, the third pressing plate 340 is connected to a side of the second pressing plate 320 facing away from the supporting surface 110 and can slide relative to the second pressing plate 320 in a direction perpendicular to the supporting surface 110, the third pressing plate 340 has a plurality of third pressing blocks 341 capable of pressing against the workpiece 20, and when the sides of the plurality of third pressing blocks 341 and the plurality of second pressing blocks 321 facing the supporting surface 110 are coplanar, there is a gap between the third pressing plate 340 and the second pressing plate 320 in the direction perpendicular to the supporting surface 110. Therefore, the first pressing plate 310, the second pressing plate 320 and the third pressing plate 340 do not interfere with each other, so as to respectively meet the pressing requirements of the workpiece 20, and the third pressing plate 340 can make up for the problem that the pressing point position is insufficient when the first pressing plate 310 and the second pressing plate 320 press the workpiece 20, so as to cooperate with the first pressing plate 310 and the second pressing plate 320 to realize the omnibearing pressing of the workpiece 20. Furthermore, when the sides of the third pressing blocks 341 and the second pressing blocks 321 facing the supporting surface 110 are coplanar, the gap between the third pressing plate 340 and the second pressing plate 320 along the direction perpendicular to the supporting surface 110 is 0.30-0.45 mm.

Specifically, the third connecting portion 342 is connected to the middle of the second connecting portion 322, and the two third press blocks 341 are respectively located at two sides of the second connecting portion 322. Thus, for the middle frame of the mobile phone, under the condition that the first pressing plate 310 and the second pressing plate 320 are arranged in the opposite direction, the first pressing plate 311 and the second pressing plate 321 can press the two ends of the middle frame, and the third pressing plate 340 is arranged to just press the middle position of the middle frame of the mobile phone, so as to make up the problem that the middle position of the middle frame of the mobile phone lacks a pressing point, so that the middle frame of the mobile phone is matched with the first pressing plate 310 and the second pressing plate 320 together to realize seamless pressing.
Specifically, the cover plate assembly 300 includes a second connector 350, the second connector 350 connecting the second presser plate 320 and the third presser plate 340. Specifically, the second connecting member 350 connects the second connecting portion 322 and the third connecting portion 342, and the two third press blocks 341 are symmetrically disposed on two sides of the second connecting member 350. Further, the second connecting member 350 is a pin, the second connecting member 350 penetrates through the third connecting portion 342 and the second connecting portion 322 along a direction perpendicular to the supporting surface 110, and at least the third connecting portion 342 can slide relative to the second connecting member 350 along an axial direction of the second connecting member 350.
