[0056] Therefore, it can be understood that the card tray processing and fixing mechanism of the present application, the bearing part, the positioning part and the pressing cylinder are all connected to the main connection part to determine the positional relationship between them, so as to ensure the accuracy of the subsequent processing steps. The installation station of the bearing part is used to support the blank and realize the preliminary positioning of the blank; the push block of the positioning part is constructed to be able to move compared to the installation station, so as to further position the blank before the pressing plate presses the blank, and further improve the accuracy of the blank positioning.

[0057] The following will describe exemplary embodiments in conjunction with the accompanying drawings. It should be noted that the components depicted in the reference drawings are not necessarily shown to scale; and the same or similar components will be given the same or similar reference numerals or similar technical terms.

[0058] The specific implementation methods of the present application are further described in detail below with reference to the accompanying drawings.

[0059] like Figure 1 As shown, the embodiment of the present application also provides a card tray processing fixing mechanism 10, including a main support 11, a main connection part 12, a bearing part 13, a positioning part 16, a pressing plate 14 and a clamping cylinder 15. The bearing part 13, the positioning part 16 and the clamping cylinder 15 are installed on the main connection part 12, the pressing plate 14 is detachably connected with the bearing part 13 and the clamping cylinder 15 and is carried on the main connection part 12, and the main connection part 12 is installed on the main support 11 and makes the main support 11, the main connection part 12, the bearing part 13, the positioning part 16, the pressing plate 14 and the clamping cylinder 15 located at a predetermined processing position, so as to fix the blank 2 in subsequent CNC processing.

[0060] Further integration Figure 2 As shown, in one embodiment, it includes a main connecting part 12, two bearing parts 13, two positioning parts 16, two pressure plates 14 and two clamping cylinders 15. The two bearing parts 13 are spaced apart at both ends of a main connecting part 12, the two positioning parts 16 are located between the two bearing parts 13, and the two pressure plates 14, the two clamping cylinders 15 and the two bearing parts 13 correspond to each other one by one.

[0061] It can be understood that a bearing part 13, a positioning part 16, a pressure plate 14 and a clamping cylinder 15 correspond to a group of working units, and another bearing part 13, another positioning part 16, another pressure plate 14 and another clamping cylinder 15 correspond to another group of working units. The two groups of working units are simultaneously arranged on the main connecting part 12, which greatly improves the processing efficiency and material utilization efficiency.

[0062] Further integration Figures 3 to 7As shown, in one embodiment, the main connection part 12 includes two opposite sides. The bearing part 13 is arranged on one side of the main connection part 12, and the bearing part 13 includes an installation station 132, and the installation station 132 is used to support the blank 2. The positioning part 16 and the bearing part 13 are arranged on the same side of the main connection part 12, and the positioning part 16 includes a push block 162 arranged toward the bearing part 13, and the push block 162 is configured to be able to move relative to the installation station 132 to position the blank 2; the pressing plate 14 is detachably connected to the bearing part 13 to cover the installation station 132. The clamping cylinder 15 includes a cylinder body 151 and a pull rod 152 connected by driving, and the cylinder body 151 is arranged on the other side of the main connection part 12, and the pull rod 152 is configured to pass through the main connection part 12, the bearing part 13 and the pressing plate 14, and is used to pull the pressing plate 14 to press against the bearing part 13 to fix the blank 2.

[0063] It can be understood that the card tray processing fixing mechanism 10, the bearing part 13, the positioning part 16 and the pressing cylinder 15 of the present application are all connected and fixed to the main connecting part 12 to ensure the accuracy of the subsequent processing steps. The installation station 132 of the bearing part 13 is used to support the blank 2 to achieve the initial positioning of the blank 2; the push block 162 of the positioning part 16 is constructed to be movable compared to the installation station 132, so as to accurately position the blank 2 before the pressing plate 14 presses the blank 2, further improving the accuracy of the positioning of the blank 2. The pressing plate 14 is detachably connected to the bearing part 13, and the pull rod 152 is constructed to pass through the main connecting part 12, the bearing part 13 and the pressing plate 14, and is used to pull the pressing plate 14 to press against the bearing part 13. After the blank 2 is positioned, the cylinder body 151 drives the pull rod 152 to pull back and press the pressing plate 14 downward, so that the pressing plate 14 presses the blank 2 set at the installation station 132 against the bearing part 13, so as to facilitate the subsequent processing of the blank 2. The card tray processing fixing mechanism 10 of the present application can realize automatic positioning and fixing, and does not need to be fixed by locking screws, so the operation efficiency is high and the fixture maintenance cost is low.

[0064] In one embodiment, the bearing portion 13 defines a first through hole 131 , which is disposed corresponding to the installation station 132 , and the pressing plate 14 defines a second through hole 142 , which is disposed corresponding to the first through hole 131 .

[0065] It can be understood that a third through hole 123 is also correspondingly provided on the main connecting part 12, and the third through hole 123 is arranged correspondingly to the first through hole 131 and the second through hole 142; along the extension direction of the pull rod 152, a first through hole 131, a second through hole 142 and a third through hole 123 are correspondingly connected, so that the pull rod 152 can pass through the main connecting part 12, the bearing part 13 and the pressure plate 14 in sequence, until the end of the pull rod 152 away from the cylinder body 151 is located on the side of the pressure plate 14 away from the bearing part 13.

[0066] In one embodiment, the pull rod 152 includes a rod body 1521 and a stop block 1522. The stop block 1522 is connected to the top of the rod body 1521 away from the cylinder body 151. The rod body 1521 is set through the first through hole 131 and the second through hole 142. The stop block 1522 is located on the side of the pressure plate 14 away from the bearing portion 13.

[0067] In one embodiment, the stopping block 1522 has different widths in at least two directions, and the second through hole 142 has different inner diameter lengths in at least two directions. The cylinder body 151 is constructed to be able to drive the pull rod 152 to rotate, so that the stopping block 1522 can switch between two states: being able to pass through the second through hole 142 and being stopped with the second through hole 142.

[0068] In this embodiment, the main connection portion 12 can be a rectangular parallelepiped, and the projections of the locking block 1522 and the second through hole 142 on the large surface of the main connection portion 12 can be roughly in the form of shapes with different side lengths, such as an ellipse, a rectangle, a diamond, etc.; at the same time, the size of the projection of the second through hole 142 is slightly larger than the size of the projection of the locking block 1522. This ensures that, when the stopping block 1522 and the second through hole 142 are in a corresponding placement state, the long side of the stopping block 1522 corresponds to the long side of the second through hole 142, and the short side of the stopping block 1522 corresponds to the short side of the second through hole 142, and the stopping block 1522 can pass through the second through hole 142 driven by the rod body 1521; when the stopping block 1522 and the second through hole 142 are in another corresponding placement state, the long side of the stopping block 1522 does not correspond to the long side of the second through hole 142, and the long side of the stopping block 1522 cannot pass through the narrower area on the second through hole 142, and the stopping block 1522 is stopped by the peripheral plate body 141 on the pressure plate 14 that surrounds the second through hole 142, and the stopping block 1522 cannot pass through the second through hole 142. Similarly, the locking block 1522 and the first through hole 131 may have the same corresponding relationship, and the first through hole 131 and the second through hole 142 may have the same placement status.

[0069] It can be understood that the state in which the stop block 1522 can pass through the second through hole 142 means that there is a relative placement position between the stop block 1522 and the second through hole 142, so that the stop block 1522 can pass through the second through hole 142. The state in which the stop block 1522 is locked with the second through hole 142 means that there is another relative placement position between the stop block 1522 and the second through hole 142, so that the stop block 1522 cannot pass through the second through hole 142 and is locked by the peripheral plate body 141 on the pressing plate 14 surrounding the second through hole 142, thereby driving the pressing plate 14 to move. In this embodiment, the peripheral plate body 141 is recessed toward the side where the bearing portion 13 is located relative to other areas of the pressing plate 14, so as to improve the clamping effect.

[0070] The corresponding assembly process can be that the cylinder body 151 rotates the rod body 1521 to adjust the placement position of the stop block 1522, so that the stop block 1522 is in a state where it can pass through the second through hole 142, the rod body 1521 passes through the load-bearing portion 13 through the first through hole 131 and passes through the pressure plate 14 through the second through hole 142, and the stop block 1522 is located on the side of the pressure plate 14 away from the load-bearing portion 13; then, the cylinder body 151 rotates the rod body 1521 to adjust the placement position of the stop block 1522, so that the stop block 1522 is staggered with the second through hole 142, the cylinder body 151 drives the rod body 1521 to move downward, the stop block 1522 cannot pass through the second through hole 142, the stop block 1522 abuts against the surface of the pressure plate 14 away from the load-bearing portion 13, and further drives the pressure plate 14 to move toward the load-bearing portion 13 to press the blank 2. Subsequently, the cylinder body 151 can be rotated again to rotate the rod body 1521 to adjust the placement position of the locking block 1522, release the locking of the locking block 1522 on the pressing plate 14, disassemble the pressing plate 14, remove the finished product and replace the blank 2.

[0071] Furthermore, the card tray processing and fixing mechanism 10 of the present application does not need to be fixed by traditional locking screw clamping. The cylinder body 151 drives the pull rod 152 to pull back and tighten so that the pressure plate 14 is pressed against the surface of the bearing part 13 with the installation station 132, thereby achieving automatic and rapid fixing, and higher working efficiency. At the same time, since the locking screw assembly is eliminated, there is no need to face the tedious process of disassembling the locking screw, avoiding damage to the threaded hole caused by repeated disassembly and assembly, and reducing the maintenance cost of the card tray processing and fixing mechanism 10.

[0072] In one embodiment, there are multiple tie rods 152, and the multiple tie rods 152 are all drivingly connected to the cylinder body 151. There are multiple installation stations 132, and the multiple tie rods 152 correspond to the multiple installation stations 132 one by one. The bearing portion 13 is provided with multiple first through holes 131, and the multiple first through holes 131 correspond to the multiple installation stations 132 one by one. The pressing plate 14 is provided with multiple second through holes 142, and the multiple second through holes 142 correspond to the multiple first through holes 131 one by one, and the multiple tie rods 152 cooperate with one pressing plate 14.

[0073] In this embodiment, the clamping cylinder 15 of the present application adopts a high-density integrated cylinder structure, and multiple tie rods 152 are integrated and connected to a cylinder body 151. One or more drive units (not shown) may be correspondingly arranged inside the cylinder body 151, which can simultaneously drive the lifting and rotation of multiple tie rods 152. For example, it may include multiple identical drive units (for example, 6 drive units correspond to 6 tie rods 152), and each drive unit drives one tie rod 152. The specific structure and detailed connection structure are not further limited, and known and feasible mechanisms in the prior art may also be selected, which will not be described in detail here.

[0074] It can be understood that a group of working units of the card tray processing and fixing mechanism 10 of the present application can be used to simultaneously locate multiple processing sites 21 on a blank 2 (each processing site 21 corresponds to an installation station 132). Correspondingly, multiple installation stations and pull rods 152 should be provided. In order for each pull rod 152 to perform related operations, multiple first through holes 131, second through holes 142 and third through holes 123 should be provided accordingly. That is, multiple pull rods 152 correspond to multiple installation stations 132 respectively, and each pull rod 152 is tightened respectively to ensure that the material on each installation station 132 can be completely fixed, thereby ensuring the processing quality, and can completely replace the traditional screw locking solution. It not only improves the processing efficiency but also ensures the processing quality to achieve automatic clamping in a small space.

[0075] In one embodiment, a plurality of tie rods 152 are arranged in a straight line and spaced apart on a cylinder body 151, a plurality of installation stations 132 are arranged in a straight line and spaced apart on a bearing portion 13, a plurality of first through holes 131 are arranged in a straight line and spaced apart on a bearing portion 13, a plurality of second through holes 142 are arranged in a straight line and spaced apart on a pressure plate 14, and the plurality of tie rods 152, the plurality of installation stations 132, the plurality of first through holes 131 and the plurality of second through holes 142 are all arranged in a straight line in the same direction.

[0076] Understandably, further combined Fig. 9As shown, the blanks 2 corresponding to the installation stations 132 arranged in a straight line in the same direction can be arranged in a straight line and have multiple processing points 21 arranged at intervals. Through the staggered setting of the processing points 21, the blank 2 can be divided into two to obtain two blanks 2 that can be used for processing without changing the size of the raw material of the blank 2, thereby greatly improving the material utilization and processing efficiency.

[0077] In one embodiment, the installation station 132 includes an installation groove 133 for placing the blank 2. The installation groove 133 is formed by a surface depression of the bearing portion 13 toward the pressure plate 14. Each first through hole 131 is correspondingly arranged in an installation station 132, and the installation groove 133 is arranged around the outer side of the first through hole 131.

[0078] It can be understood that the mounting groove 133 is formed by the surface depression of the bearing portion 13 toward the pressing plate 14, which is convenient for placing and initially positioning the blank 2. Each first through hole 131 is correspondingly arranged in an installation station 132, and the mounting groove 133 is arranged around the outer side of the first through hole 131, so that the pull rod 152 is roughly located in the central area of ​​the installation station 132. When the pull rod 152 is pulled down, the force of the locking block 1522 pressing the pressing plate 14 to the periphery of the installation station 132 is relatively balanced, which ensures the fixing strength while reducing the probability of the blank 2 shaking due to uneven force, thereby improving the accuracy of subsequent CNC processing.

[0079] In one embodiment, the pressing plate 14 is disposed on a side of the bearing portion 13 away from the main connecting portion 12. Two positioning posts 134 are disposed at both ends of the bearing portion 13, and the plurality of installation stations 132 are located between the two positioning posts 134. Two positioning holes 143 are provided at both ends of the pressing plate 14, and the plurality of second through holes 142 are located between the two positioning holes 143.

The push block 162 is provided with a positioning protrusion 163 on the side facing the bearing portion 13, and the positioning protrusion 163 is arranged corresponding to the installation station 132. The side push cylinder 161 is used to push the push block 162 to move toward the bearing portion 13, so that the positioning protrusion 163 moves to the installation station 132 to position the blank 2.

[0082] In this embodiment, each positioning portion 16 may include three side-push cylinders 161, each side-push cylinder 161 is arranged between two adjacent installation stations 132, and the side-push cylinder 161 can use two mutually cooperating push rods with wedge-shaped surfaces (not shown in the figure) to achieve side pushing.

[0083] In this embodiment, the end of the positioning protrusion 163 facing the installation station 132 may have an inclined surface, and its inclination angle is inclined from the side closer to the carrying portion 13 to the side farther away from the carrying portion 13. After the positioning protrusion 163 contacts the carrying portion 13, its tip may be slightly higher than the surface of the carrying portion 13 where the installation station 132 is provided, taking into account both positioning and buffering.

[0084] In one embodiment, the positioning portion 16 further includes two reset blocks 164 and two elastic members 165. The two reset blocks 164 are respectively arranged on both sides of the interval between the push blocks 162, and the bearing portion 13 and the side thrust cylinder 161 are respectively located on both sides of the other interval between the push blocks 162. Each elastic member 165 is arranged in a reset block 164, and both ends of the interval between the elastic members 165 are respectively in contact with the reset block 164 and the push block 162, so as to push the push block 162 away from the bearing portion 13 when the force of the side thrust cylinder 161 is removed.

[0085] In this embodiment, the push block 162 is generally arranged in a long strip shape, and the push block 162 is arranged generally parallel to the bearing portion 13. Two reset blocks 164 are respectively arranged on opposite sides of the push block 162 and the bearing portion 13 along the length direction, and the reset blocks 164 are fixed on the main connecting portion 12. Each reset block 164 is provided with a receiving groove 1641, and the two receiving grooves 1641 respectively accommodate the two opposite ends of the push block 162. The elastic member 165 can be a spring or an elastic rubber rod.

[0086] It can be understood that the corresponding actuation process can be: when the blank 2 is placed on the load-bearing part 13, the side push cylinder 161 pushes the push block 162 toward the load-bearing part 13, and the multiple positioning protrusions 163 respectively position the parts of the blank 2 placed on the multiple installation stations 132, and at the same time the elastic member 165 is compressed and contracts to store energy; when the processing is completed, the side push cylinder 161 retracts, and the push block 162 is pushed away from the load-bearing part 13 by the elastic member 165, and at the same time the positioning protrusion 163 is disengaged from the installation station 132, and the positioning part 16 is reset.
