[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] Example 1: Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 8 As shown, a rotating bracket pressing device is provided, comprising: a box-shaped shell 2, a base 1 is installed on the lower end of the shell 2, a mounting carrier is provided for the shell 2 through the base 1, and a fixing plate 5 is set on the upper end of the base 1, a mounting carrier is provided for components such as the mounting column 6 through the fixing plate 5, and then the mounting column 6 is installed on the middle of the upper end of the fixing plate 5, and a mounting carrier is provided for components such as the positioning column 69 through the mounting column 6, and the outer end surface of the mounting column 6 is recessed inward to form two symmetrically arranged second positioning grooves 61 extending to the upper end of the mounting column 6, and a positioning column 69 located between the two second positioning grooves 61 and forming an integrated structure with the mounting column 6 is set on the upper end of the mounting column 6, and the positioning column 69 is used in conjunction with the two second positioning grooves 61 to position and install the small bracket workpiece, and a sensor 691 extending to the upper end of the mounting column 6 and located outside the positioning column 69 is installed in the mounting column 6, and the sensor 691 is used to determine whether the small bracket workpiece is placed in reverse.

[0036] The two electromagnets 52 located on the left and right sides of the mounting column 6 are symmetrically installed on the upper end of the fixed plate 5, and the two magnetic plates 42 located on the left and right sides of the mounting column 6 and directly above the two electromagnets 52 are symmetrically arranged on the lower end of the positioning frame plate 4, and the magnetic plates 42 and the electromagnets 52 are arranged to repel each other. The magnetic plates 42 and the electromagnets 52 are used in conjunction with each other to elastically connect the positioning frame plate 4 and the fixed plate 5, and then four guide pillars 51 located on the outside of the electromagnets 52 and the outside of the magnetic plates 42 are respectively installed on the four corner positions of the upper end of the fixed plate 5, the four guide pillars 51 all penetrate the positioning frame plate 4, and the guide pillars 51 are slidably connected to the positioning frame plate 4, and the four guide pillars 51 are used in conjunction to guide the movement of the positioning frame plate 4, and a first positioning groove 41 is formed in a downward depression on the upper end surface of the positioning frame plate 4, and the chassis workpiece is positioned and installed through the first positioning groove 41.

[0037] The pressure plate 31 is movably arranged in the shell 2, and a mounting carrier is provided for the pressure block 32 through the pressure plate 31, and the movable part passes through the shell 2 and the fixed part of the lifter 3 connected to the pressure plate 31 is installed on the upper end of the shell 2, and the pressure plate 31 is driven to move up and down through the lifter 3. The lifter 3 can adopt a hydraulic cylinder, and then the pressure block 32 located just above the positioning frame plate 4 is set on the lower end of the pressure plate 31. The chassis workpiece is pressed by the pressure block 32, and four guide rods 33 located on the outside of the positioning frame plate 4, the outside of the fixed plate 5 and the outside of the pressure block 32 are respectively installed at the four corner positions inside the shell 2, and the four guide rods 33 all pass through the pressure plate 31, and the pressure plate 31 is slidably connected to the guide rods 33. The four guide rods 33 are used together to guide the movement of the pressure plate 31.

[0038] When in use, first disconnect the circuits of the two electromagnets 52, so that the positioning frame plate 4 and other components move downward to the limit position under their own weight. At this time, the upper part of the mounting post 6 and the positioning post 69 are located on the positioning frame plate 4 and exposed on the top. Then, place the small bracket workpiece on the mounting post 6, and insert the two inserting plates of the small bracket workpiece into the two second positioning grooves 61 respectively. With the help of the positioning post 69, the small bracket workpiece is positioned and placed.

[0039] At the same time, the sensor 691 detects the distance between the workpiece and the small bracket. If the detected distance is the same as the preset distance, it is determined that the small bracket is correctly placed. If there is a difference between the detected distance and the preset distance, it is determined that the small bracket is incorrectly placed. Then the small bracket is taken out, rotated, and placed again, so as to timely determine whether the small bracket is placed in the wrong direction, effectively avoiding the phenomenon of unqualified subsequent pressed products caused by the reverse placement of the small bracket, and effectively ensuring the pressing effect and quality.

[0040] Then, the circuits of the two electromagnets 52 are turned on, thereby causing the electromagnets 52 to generate a magnetic field. Since the electromagnets 52 and the magnetic plates 42 are arranged to repel each other, a repulsive force is generated between the electromagnets 52 and the magnetic plates 42. Under the action of the repulsive force, the positioning frame plate 4 moves upward to the limit position, and then the chassis workpiece is placed on the first positioning groove 41, thereby positioning the chassis workpiece on the positioning frame plate 4, and then the lifter 3 is started to drive the pressing plate 31 to move downward, thereby causing the pressing block 32 to move downward and contact the positioned chassis workpiece, and then the pressing plate 31 and the pressing block 32 continue to move downward, thereby applying downward pressure to the chassis workpiece and the positioning frame plate 4, thereby causing the chassis workpiece, the positioning frame plate 4 and the magnetic plate 42 to move downward, thereby performing a pressing process between the chassis workpiece and the chassis workpiece;

[0041] When the pressing is completed, the lifter 3 is used to move the pressing plate 31 and other components back to their original positions. At this time, the repulsive force formed between the electromagnet 52 and the magnetic plate 42 will drive the magnetic plate 42 to move upward, and then the positioning frame plate 4 will move upward, thereby pushing the finished product formed by pressing upward, and then the finished product is taken out to realize the positioning mechanical pressing operation, effectively reducing the probability of improper assembly and loss of the finished product due to manual pressing factors, effectively reducing production costs, and effectively ensuring the pressing effect and quality.

[0042] Example 2: In the current assembly process, the small bracket workpiece is initially positioned through the coordinated cooperation of the mounting post 6, the second positioning slot 61, the positioning post 69, and the sensor 691. The chassis workpiece is then precisely placed directly above the small bracket workpiece using the positioning frame 4 and the first positioning slot 41. Finally, the two are mechanically pressed together using the lifter 3, the pressure plate 31, and the pressure block 32. However, in actual operation, it was found that the placement of the small bracket workpiece on the mounting post 6 had obvious flaws, making it very easy for the workpiece to be partially positioned or tilted, significantly increasing the risk of damage to the workpiece during the subsequent pressing operation.

[0043] In order to solve the above problems, Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, the upper end surface of the positioning column 69 is recessed downward to form a recessed hole 62 extending into the mounting column 6. The recessed hole 62 provides installation space for components such as the movable plate 64. The movable plate 64 is slidably connected in the recessed hole 62. The movable plate 64 provides an installation carrier for components such as the round rod 67. The round rod 67 extending from the upper side of the recessed hole 62 is set on the middle part of the upper end of the movable plate 64. The round rod 67 provides an installation carrier for the tapered column 68. The first elastic member 63 is then installed between the lower end of the movable plate 64 and the bottom end of the recessed hole 62. The first elastic member 63 returns the movable plate 64 and other components to their original position. The first elastic member 63 can be a spring.

[0044] The outer annular end surface of the positioning column 69 is recessed inward to form a plurality of mounting grooves 661 located outside the recessed hole 62. The mounting grooves 661 provide installation space for components such as the correction plate 65. The plurality of correction plates 65 are slidably connected to the plurality of mounting grooves 661, and the correction plate 65 is provided with an inclined surface arranged with a high outer side and a low inner side toward the outer end. The plurality of correction plates 65 are used in conjunction to correct the small bracket workpiece placed therein, and the plurality of push rods 66 extending into the recessed hole 62 are respectively arranged on the middle part of the inner end of the plurality of correction plates 65, and the plurality of push rods 66 are provided with an inclined surface toward the inner end, and the correction plate 65 is pushed by the push rods 66.

[0045] A conical column 68 that is wide at the top and narrow at the bottom is installed on the outer end of the round rod 67, and multiple inclined surfaces are fitted on the conical surface of the conical column 68. Through the conical column 68, multiple push rods 66 are moved outward synchronously, and multiple second elastic members 662 located on the outside of the push rods 66 are set on the inner end of the correction plate 65, and the other end of the second elastic member 662 is connected to the inner wall of the installation groove 661. Multiple second elastic members 662 are used in combination to return the correction plate 65 to its original position. The second elastic member 662 can be a spring.

[0046] When in use, first disconnect the circuits of the two electromagnets 52, so that the positioning frame plate 4 and other components move downward to the limit position under their own weight. At this time, the upper part of the mounting post 6 and the positioning post 69 are located on the positioning frame plate 4 and exposed on the top. Then, place the small bracket workpiece on the mounting post 6, and insert the two inserting plates of the small bracket workpiece into the two second positioning grooves 61 respectively. With the help of the positioning post 69, the small bracket workpiece is positioned and placed.

[0047] At the same time, the sensor 691 detects the distance between the workpiece and the small bracket. If the detected distance is the same as the preset distance, it is determined that the small bracket is correctly placed. If there is a difference between the detected distance and the preset distance, it is determined that the small bracket is incorrectly placed. Then, the small bracket is taken out, the workpiece is rotated, and then re-placed, so as to timely determine whether the small bracket is placed in the wrong direction.

[0048] Then, the round rod 67 is pressed downward, so that the movable plate 64 and the tapered column 68 move downward. The downward movement of the movable plate 64 compresses the first elastic member 63, so that the first elastic member 63 generates an elastic force. At the same time, because the inclined surfaces of the multiple push rods 66 are all in contact with the tapered surface of the tapered column 68, the downward movement of the tapered column 68 causes the multiple push rods 66 to move outward synchronously, thereby causing the multiple correction plates 65 to move outward and enter the upper end of the small bracket workpiece, thereby correcting the placed small bracket workpiece. At the same time, the outward movement of the movable plate 64 stretches the second elastic member 662, so that the second elastic member 662 generates an elastic force.

[0049] Then, the round rod 67 is released, and the movable plate 64, the round rod 67 and the tapered column 68 move upward and return to their original positions under the elastic force of the first elastic member 63. At the same time, the correction plate 65 and the push rod 66 move inward and return to their original positions under the elastic force of the second elastic member 662, and the inclined surface of the push rod 66 is always in contact with the tapered surface of the tapered column 68, so as to achieve the correction of the small bracket workpiece, effectively reduce the probability of the small bracket workpiece being warped or tilted in the placement position, effectively reduce the probability of damage during the pressing operation, and effectively ensure the pressing effect and quality;

[0050] Then, the circuits of the two electromagnets 52 are turned on, and the repulsive force generated between the electromagnet 52 and the magnetic plate 42 is used to move the positioning frame plate 4 upward to the extreme position, and then the chassis workpiece is placed on the first positioning groove 41, so that the chassis workpiece is positioned and placed on the positioning frame plate 4, and then the lifter 3, the pressure plate 31 and the pressure block 32 are used to move the chassis workpiece, the positioning frame plate 4 and the magnetic plate 42 downward, so that the chassis workpiece and the chassis workpiece are pressed together. When the pressing is completed, the lifter 3 is used to move the pressure plate 31 and other components upward and back to their original position. At this time, the repulsive force formed between the electromagnet 52 and the magnetic plate 42 will drive the magnetic plate 42 to move upward, and then the positioning frame plate 4 will move upward, thereby pushing the finished product formed by pressing upward, and then the finished product is taken out.

[0051] Although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
