DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Embodiment 1

[0041] Reference Figure 1 - Fig.11 A rotary shell pressing device for assembling a connector shield shell comprises an operating table 1, and the rotary shell pressing device comprises:

[0042] A mounting frame 2 mounted on the top of the operating table 1, a screw slide 3 mounted on the top of the mounting frame 2, a moving plate 4 fixedly connected to the moving end of the screw slide 3, and a first hydraulic push rod 5 bolted to the side wall of the moving plate 4;

[0043] A mounting frame 6 disposed at the output end of the first hydraulic push rod 5, and a rotating shell pressing mechanism 7 disposed in the middle of the mounting frame 6;

[0044] A workpiece positioning seat 8 fixedly connected to the top of the operating table 1, a shielding shell bearing seat 9 and a joint bearing seat 10 arranged on both sides of the workpiece positioning seat 8, a bearing positioning component 11 arranged inside the shielding shell bearing seat 9, and a joint supporting component 12 arranged inside the joint bearing seat 10;

[0045] A positioning mechanism 13 is arranged on the top of the operating platform 1 .

[0046] During use, the shielding shell to be assembled is placed on the bearing and positioning component 11 in the shielding shell bearing seat 9 to ensure that the shielding shell is stable and accurately positioned. At the same time, the corresponding joint is placed on the joint support component 12 in the joint bearing seat 10 to keep the position of the joint fixed and easy to assemble. The I-type positioning seat 8 positions the shielding shell bearing seat 9 and the joint bearing seat 10, and the shielding shell bearing seat 9 and the joint bearing seat 10 are clamped and positioned by the positioning mechanism 13. The movable plate 4 can be driven to move by the screw slide 3. First, the movable plate 4 is driven to be located above the shielding shell bearing seat 9. The output of the first hydraulic push rod 5 enables the rotating shell pressing mechanism 7 to clamp and take the shielding shell in the shielding shell bearing seat 9. Then, the installation frame 6 is located above the joint bearing seat 10 through the conveyance of the screw slide 3 and the first hydraulic push rod 5. At this time, the rotating shell pressing mechanism 7 rotates and presses the shielding shell, so that the shielding shell is stably and tightly installed on the joint, which improves the stability of the shielding shell pressing and improves the effect of the shielding shell pressing. Embodiment 2

[0047] like Figure 2 , Figure 4 , Figure 5 and Fig.11 As shown, the rotary shell pressing mechanism 7 includes a positioning clamping assembly 71 and a rotary driving assembly 72 disposed in the middle of the mounting frame 6;

[0048] The positioning clamping assembly 71 includes: three positioning cylinders 7101 connected to the middle of the mounting frame 6 by bearings, a clamping box 7102 fixedly connected to the top of the positioning cylinder 7101, two slide bars 7103 fixedly connected to the inside of the clamping box 7102, a clamping block 7104 arranged on the two slide bars 7103, the side wall of the clamping block 7104 is arranged in a semicircular shape, a second hydraulic push rod 7105 arranged on both sides of the clamping box 7102, a connecting seat 7106 fixedly connected to the output end of the second hydraulic push rod 7105, a driving bar 7107 hinged at both ends of the connecting seat 7106, a connecting bar 7108 and a pulling bar 7109 hinged at one end of the driving bar 7107 (such as Fig.11 As shown), the other end of the connecting strip 7108 is hingedly matched with the clamping box 7102, the other end of the pulling strip 7109 is hingedly matched with the clamping block 7104, fixedly connected to the semicircular plug block 7110 on the side wall of the clamping block 7104, the semicircular plug block 7110 is adapted to the groove of the shielding shell, and fixedly connected to the limit head 7111 on the side wall of the semicircular plug block 7110, the limit head 7111 is adapted to the pin hole of the shielding shell.

[0049] When in use, the output of the first hydraulic push rod 5 makes the positioning cylinder 7101 sleeved on the shielding shell, and the second hydraulic push rod 7105 is started, and its output end pushes the connecting seat 7106 to move, and then through the hinge relationship between the driving bar 7107, the connecting bar 7108 and the pulling bar 7109, the clamping block 7104 is driven to slide along the sliding bar 7103, and at the same time, the shielding shell can be locked after the clamping block 7104 contacts with the shielding shell. At this time, the driving bar 7107 forms a straight line between the connecting bar 7108 and the pulling bar 7109, so that the connecting bar 7108 and the pulling bar 7109 stably support the clamping block 7104, thereby realizing self-locking of the clamping block 7104 and preventing the clamping block 7104 from being clamped. In order to solve the problem of shaking or displacement, the loosening of the clamping block 7104 caused by the unloading force of the second hydraulic push rod 7105 is avoided. Since the side wall of the clamping block 7104 is semicircular, when the two clamping blocks 7104 move toward each other, they will jointly clamp the outside of the shielding shell to achieve preliminary positioning and fixation. At the same time, the semicircular plug block 7110 is inserted into the groove of the shielding shell, and the limit head 7111 is matched with the pin hole of the shielding shell, which further enhances the stability and accuracy of the clamping. Through the adaptation of the positioning cylinder 7101, the clamping block 7104, the semicircular plug block 7110 and the limit head 7111 to the shape of the shielding shell, the shielding shell can be stably clamped to avoid displacement of the shielding shell when the shell is pressed. Embodiment 3

[0050] like Figure 3 As shown, the rotary drive assembly 72 includes: a partition 7201 arranged on the inner wall of the mounting frame 6, a box cover 7202 arranged on the top of the clamping box 7102, the middle part of the box cover 7202 is a convex setting, a driving shaft 7203 fixedly connected to the top of the box cover 7202, the driving shaft 7203 is connected to the bearing of the partition 7201, a gear 7204 is arranged on the top of the driving shaft 7203, a third hydraulic push rod 7205 installed on the side wall of the mounting frame 6, and a driving rack 7206 fixedly connected to the output end of the third hydraulic push rod 7205, and the driving rack 7206 is meshed with the gear 7204.

[0051] When in use, the output of the first hydraulic push rod 5 causes the positioning cylinder 7101 to carry the shielding shell into contact with the joint, and the output of the third hydraulic push rod 7205 causes the driving rack 7206 to mesh with the three sets of gears 7204, so that the three sets of gears 7204 move synchronously, and the gear 7204 rotates through the drive shaft 7203, the drive box cover 7202, the clamping box 7102 and the positioning cylinder 7101, so that the shielding shell can rotate when the shell is pressed, thereby avoiding damage to the shielding shell due to excessive punching pressure on the shielding shell. The shielding shell can fit better with the joint during the rotation and pressing process, thereby improving the effect of pressing the shielding shell. Embodiment 4

[0052] like Fig.10 As shown, the bearing and positioning assembly 11 includes: three bearing heads 111 fixedly connected to the inside of the shielding shell bearing seat 9, the bearing heads 111 are adapted to the shielding shell, a mounting hole 112 is arranged on the top of the bearing head 111, a mounting cylinder 113 is arranged inside the mounting hole 112, a supporting spring 114 is installed inside the mounting cylinder 113, a positioning head 115 fixedly connected to one end of the supporting spring 114, and a ball 116 embedded in the middle of the positioning head 115, and the ball 116 is adapted to the pin hole of the shielding shell.

[0053] When in use, the shielding shell is put on the bearing head 111. At this time, the shielding shell squeezes the positioning head 115 to make the support spring 114 shrink and enter the interior of the installation tube 113. Then the shielding shell is rotated until the ball 116 coincides with the pin hole position of the shielding shell. The support spring 114 is reset to make the ball 116 fit into the pin hole. At this time, the positioning support of the shielding shell is realized, so that after the shielding shell enters the interior of the positioning tube 7101, the position of the pin hole is adapted to the position of the limit head 7111. Embodiment 5

[0054] like Figure 8 As shown, the connector support assembly 12 includes: three plugs 121 fixedly connected to the inside of the connector bearing seat 10, and slots 122 adapted to the connector are formed on the side walls of the plugs 121, and the slots 122 are snap-fitted with the connector.

[0055] When in use, the slot 122 provided inside the plug 121 is matched with the pin of the connector, so that the connector is supported in a limited position, thereby preventing the connector from rotating when the shielding shell and the connector are rotated and pressed together. Embodiment 6

[0056] like Figure 6 and Figure 7 As shown, the positioning mechanism 13 includes: a base plate 131 fixedly connected to the bottom of the operating table 1, a driving motor 132 arranged on the top of the base plate 131, a driving plate 133 fixedly connected to the output end of the driving motor 132, a connecting rod 134 hinged at both ends of the driving plate 133, a plurality of sliding frames 135 fixedly connected to the side wall of the base plate 131, a slider 136 arranged inside the sliding frame 135, a cross plate 137 fixedly connected to the side walls of the two sliders 136, the connecting rod 134 is hingedly matched with the cross plate 137, a push-pull plate 138 fixedly connected to both ends of the cross plate 137, the push-pull plate 138 is movably connected to the operating table 1, and a clamping plate 139 fixedly connected to one end of the two push-pull plates 138, the clamping plate 139 is L-shaped, and the clamping plate 139 is adapted to the shielding shell bearing seat 9 and the connector bearing seat 10.

[0057] When in use, first start the driving motor 132, the output end of the driving motor 132 drives the driving plate 133 to rotate, and the connecting rods 134 at both ends of the driving plate 133 swing accordingly, and the other end of the connecting rod 134 is hinged with the cross plate 137, so as the driving plate 133 rotates, the connecting rod 134 will push or pull the cross plate 137 to move in the horizontal direction, and the two ends of the cross plate 137 are respectively connected to the slider 136, and the slider 136 slides inside the slide frame 135, ensuring the stability and guidance of the movement of the cross plate 137, and the movement of the cross plate 137 further drives the fixed connection with it The push-pull plate 138 moves. Since the push-pull plate 138 is movably connected to the operating table 1, the push-pull plate 138 can slide smoothly along the surface of the operating table 1, and the clamping plate 139 (L-shaped setting) at one end of the push-pull plate 138 approaches or moves away from the shielding shell bearing seat 9 and the connector bearing seat 10 accordingly. When the clamping plate 139 moves to a position in contact with the shielding shell bearing seat 9 and the connector bearing seat 10, since the clamping plate 139 is L-shaped, it can fit tightly and clamp the edge portion of the bearing seat, thereby achieving stable clamping and positioning of the shielding shell bearing seat 9 and the connector bearing seat 10. Embodiment 7

[0058] like Figure 4 As shown, the top of the box cover 7202 is fixedly connected to the limiting ring 14, and the top of the limiting ring 14 contacts the top of the shielding shell.

[0059] The setting of the limiting ring 14 can limit the shielding shell entering the positioning tube 7101, so as to facilitate the adaptation of the clamping block 7104 and the semicircular plug block 7110 to the groove of the shielding shell. Embodiment 8

[0060] like Figure 5 As shown, two rubber strips 15 are inlaid on the side walls of the semicircular plug block 7110 , and anti-slip protrusions 16 are provided on the side walls of the rubber strips 15 .

[0061] By providing the rubber strip 15 and the anti-skid protrusions 16, the friction between the semicircular plug 7110 and the shielding shell can be increased, while the semicircular plug 7110 is protected to prevent the semicircular plug 7110 from damaging the shielding shell. Embodiment 9

[0062] like Figure 3 As shown, a right-angle bar 17 is provided on the top of the partition 7201 , and the right-angle bar 17 is movably connected to the driving rack 7206 .

[0063] By providing the right-angle bar 17, the movement of the driving rack 7206 can be guided, thereby improving the stability of the movement of the driving rack 7206. Embodiment 10

[0064] like Figure 1As shown, two conveyor belt groups 18 are arranged in the middle of the operating platform 1 , and the conveyor belt groups 18 are used to convey the shielding shell bearing seat 9 and the connector bearing seat 10 .

[0065] The arrangement of the conveyor belt group 18 can facilitate the conveyance of the shielding shell bearing seat 9 and the connector bearing seat 10, thereby realizing continuous and automated loading and unloading of the shielding shell and the connector, and realizing continuous and automated shell pressing operations on the shielding shell.

[0066] It should be noted that the specific models and specifications of the first hydraulic push rod 5, the second hydraulic push rod 7105, the third hydraulic push rod 7205, the drive motor 132 and the screw slide 3 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it is not repeated here.

[0067] The present invention can be explained by the following operation mode:

[0068] The shielding shell and the connector are positioned and loaded by putting the shielding shell on the loading head 111. At this time, the shielding shell squeezes the positioning head 115 to shrink the supporting spring 114 into the interior of the mounting tube 113. Then the shielding shell is rotated until the ball 116 coincides with the pin hole of the shielding shell. The supporting spring 114 is reset to make the ball 116 fit into the pin hole. The connector is inserted into the slot 122. The slot 122 opened inside the plug 121 is adapted to the pin of the connector, so that the connector is supported in a limited position.

[0069] The conveyor belt set 18 is provided with slide rails for the shielding shell bearing seat 9 and the joint bearing seat 10 to slide horizontally, which is the existing technology and will not be described in detail.

[0070] The worker places the shielding shell bearing seat 9 and the joint bearing seat 10 on the corresponding slide rails, and the conveyor belt group 18 conveys the shielding shell bearing seat 9 and the joint bearing seat 10. The output end of the driving motor 132 drives the driving plate 133 to rotate, and the connecting rods 134 at both ends of the driving plate 133 swing accordingly. The other end of the connecting rod 134 is hinged with the cross plate 137. Therefore, as the driving plate 133 rotates, the connecting rod 134 will push or pull the cross plate 137 to move in the horizontal direction. The two ends of the cross plate 137 are respectively connected to the slider 136, and the slider 136 is in the slide frame 135. The movement of the horizontal plate 137 further drives the push-pull plate 138 fixedly connected thereto to move. Since the push-pull plate 138 is movably connected to the operating table 1, the push-pull plate 138 can slide smoothly along the surface of the operating table 1, and the clamping plate 139 (L-shaped setting) at one end of the push-pull plate 138 moves closer to or away from the shielding shell bearing seat 9 and the connector bearing seat 10 accordingly. When the clamping plate 139 moves to a position in contact with the shielding shell bearing seat 9 and the connector bearing seat 10, since the clamping plate 139 is L-shaped, it can fit tightly and clamp the edge of the bearing seat.

[0071] The movable plate 4 is driven to move by the screw slide 3. First, the movable plate 4 is driven to be located above the shielding shell bearing seat 9. The output of the first hydraulic push rod 5 makes the positioning cylinder 7101 sleeved on the shielding shell, and the second hydraulic push rod 7105 is started. Its output end pushes the connecting seat 7106 to move, and then through the hinge relationship of the driving bar 7107, the connecting bar 7108 and the pulling bar 7109, the clamping block 7104 is driven to slide along the slide bar 7103. At the same time, the shielding shell can be locked after the clamping block 7104 contacts with the shielding shell. Since the side wall of the clamping block 7104 is semicircular, when the two clamping blocks 7104 move toward each other, they will jointly clamp the outside of the shielding shell to achieve preliminary positioning and fixation. At the same time, the semicircular plug block 7110 is inserted into the groove of the shielding shell, and the limit head 7111 is adapted to the pin hole of the shielding shell.

[0072] When the output of the first hydraulic push rod 5 makes the positioning cylinder 7101 carry the shielding shell to contact the joint, the output of the third hydraulic push rod 7205 makes the driving rack 7206 mesh with the three sets of gears 7204, so that the three sets of gears 7204 move synchronously, and the gear 7204 enters the driving box cover 7202, the clamping box 7102 and the positioning cylinder 7101 through the driving shaft 7203 to rotate, so that the shielding shell can realize rotational movement when the shell is pressed.

[0073] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
