[0027] The present utility model will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and implement it, but the embodiments cited are not intended to limit the present utility model.

[0028] Embodiment

[0029] Referring to Figures 1 - 5 As shown, a shell press-fitting positioning buffer mechanism of the present utility model includes:

[0030] A base 1, the base 1 is provided with a press head 3 that moves up and down, the press head 3 is connected to the output end of a lifting driving member 2, and a positioning block 10 is arranged below the press head 3;

[0031] A turntable 7, there are buffer fixtures 6 on both sides of the turntable 7 along the radial direction, the buffer fixtures 6 are arranged between the press head 3 and the positioning block 10, and the turntable 7 is connected to the output end of a rotating driving member 9;

[0032] The buffer fixture 6 includes: a bushing 61 arranged on the turntable 7, a limit sleeve 66 movably connected up and down to the bushing 61, a shaft body 611 arranged in the limit sleeve 66, an elastic member 612 with both ends respectively connected to the limit sleeve 66 and the bushing 61, and a support pin 65 arranged at the end of the shaft body 611 and used to hold the product to be press-fitted.

[0033] A shell press-fitting positioning and buffering mechanism according to the present utility model. When it is necessary to press-fit the shell, the product to be press-connected is placed on the support pin 65. The lifting drive member 2 drives the pressing head 3 to move downward. The pressing head 3 contacts and presses down the product to be press-connected. When the pressing head 3 presses down, the product to be press-connected will transmit the pressure to the support pin 65, and then to the shaft body 611 and the limit sleeve 66. Since the limit sleeve 66 is connected to the bushing 61 through the elastic member 612, the elastic member 612 will be compressed, thus playing a buffering role and reducing the impact force on the product to be press-connected during the press-fitting process, avoiding damage to the product. At the same time, the rotation drive member 9 can drive the turntable 7 to rotate, so that the two buffering jigs 6 on the turntable 7 can work alternately, improving work efficiency. When the product on one buffering jig 6 is press-fitted, the turntable 7 rotates to move the other buffering jig 6 with the product to be press-connected to the lower part of the pressing head 3 for the next press-fitting operation.

[0034] First, place the product to be press-connected on the support pin 65 of one of the buffering jigs 6. Then, the lifting drive member 2 drives the pressing head 3 to move downward. The pressing head 3 contacts the product to be press-connected and applies pressure. The product to be press-connected transmits the pressure to the support pin 65, the shaft body 611 and the limit sleeve 66, compressing the elastic member 612 to play a buffering role. When the press-fitting is completed, the lifting drive member 2 drives the pressing head 3 to move upward. Next, the rotation drive member 9 drives the turntable 7 to rotate 180 degrees, rotating the other buffering jig 6 with the product to be press-connected to the lower part of the pressing head 3, and repeating the above press-fitting process. Thus, continuous shell press-fitting operations are cyclically realized, and the elastic member 612 is a compression spring.

[0035] The bushing 61 is axially provided with a first through hole 69 and a second through hole 610. The first through hole 69 and the second through hole 610 communicate and penetrate through the bushing 61. The inner diameter of the first through hole 69 is larger than that of the second through hole 610. Due to the larger inner diameter of the first through hole 69, the shaft body 611 sleeve can move relatively up and down within the bushing 61. At the same time, the smaller inner diameter of the second through hole 610 can play a guiding and limiting role in the movement of the shaft body 611. A circlip 614 is also clamped at the bottom of the shaft body 611 to limit the shaft body 611 upward.

[0036] A raised portion 62 is provided around the circumference of the shaft body 611. The raised portion 62 is disposed within the second through hole 610. The size of the raised portion 62 is between the first through hole 69 and the second through hole 610. The lower end of the elastic member 612 abuts against the raised portion 62. Since the size of the raised portion 62 is between the first through hole 69 and the second through hole 610, the raised portion 62 cannot enter the first through hole 69 through the second through hole 610, thereby ensuring the position range of the shaft body 611 within the bushing 61. During press-fitting, the raised portion 62 on the shaft body 611 will be subjected to a downward pressure from the limiting sleeve 66. At this time, the lower end of the elastic member 612 abuts against the raised portion 62, causing the elastic member 612 to be compressed. The elastic member 612 absorbs and buffers the pressure through its own elastic deformation, thereby reducing the impact force on the product to be press-connected during the press-fitting process.

[0037] The limiting sleeve 66 is movably connected within the first through hole 69. A groove is axially formed within the limiting sleeve 66. The groove formed within the limiting sleeve 66 provides a abutting position for the upper end of the elastic member 612. The upper end of the elastic member 612 extends and abuts against the end of the groove, and its depth and shape are adapted to the upper end of the elastic member 612.

[0038] The limiting sleeve 66 is provided with a third through hole 64. The shaft body 611 is fixedly connected with a limiting shaft 63. The limiting shaft 63 extends into the third through hole 64. The height of the third through hole 64 is greater than the outer diameter of the limiting shaft 63, ensuring that the up and down movement of the shaft body 611 within the limiting sleeve 66 has a certain guiding property, while restricting the movement of the shaft body 611 in other directions. Both ends of the positioning block 10 are provided with arc chamfers, enabling the shaft body 611 to move upward when it contacts the chamfers.

[0039] The end of the limiting sleeve 66 is provided with a limiting block 613. The shape and size of the limiting block 613 are adapted to the product to be press-connected, such as a connector, etc. During the press-fitting process, after the product to be press-connected is placed on the support pin 65, the limiting block 613 will contact the positioning part of the product, thereby limiting and positioning the product. The installation position and angle of the limiting block 613 satisfy the limiting and positioning of the product.

[0040] The bushing 61 is axially provided with an anti-rotation shaft 68. The raised portion 62 is provided with a fourth through hole 67 adapted to the anti-rotation shaft 68, preventing the shaft body 611 from rotating during the working process without affecting the up and down movement. Inserting the anti-rotation shaft 68 into the fourth through hole 67 enables the shaft body 611 to only move axially along the anti-rotation shaft 68 during the up and down movement and cannot rotate.

[0041] On both sides of the turntable 7, a first sensor 4 and a second sensor 8 are respectively arranged. The first sensor 4 is arranged on one side of the press head 3, and the second sensor 8 is arranged on the radial opposite side of the first sensor 4. The first sensor 4 is close to the press head 3 and can timely detect the working conditions below the press head 3, such as whether the product is placed in place and whether the press-fitting process is normal. The second sensor 8 is located on the radial opposite side of the first sensor 4 and can monitor whether there is a product on the buffer jig 6 on the other side of the turntable 7. The two sensors can be of types such as photoelectric sensors and proximity sensors. The sensors are connected to the control system through signal lines and transmit the detected signals to the control system in real time so that the control system can perform corresponding operations and adjustments according to the information.

[0042] It further includes a code scanning mechanism, which includes: a code scanning bracket 11 arranged on one side of the press head 3, and a code scanner 5 connected to the code scanning bracket 11. The code scanner 5 is connected to the code scanning bracket 11 through a connecting piece, and the connecting piece can adjust the angle and position of the code scanner 5 to meet the code scanning requirements of different products. The code scanner 5 can adopt common two-dimensional code or bar code scanning devices. When the product is placed on the buffer jig 6 for press-fitting, the code scanner 5 will scan the two-dimensional code or bar code on the product and transmit the scanned information to the control system for processing and recording.

[0043] Embodiment 2

[0044] This embodiment also discloses a housing press-fitting device, a housing press-fitting positioning buffer mechanism as described in Embodiment 1.

[0045] The housing press-fitting device described in this embodiment further includes an automatic feeding mechanism: including a material bin, a conveying track and a manipulator. The material bin is used to store the housings to be press-fitted. The conveying track conveys the housings from the material bin to the vicinity of the press-fitting position. The conveying track can be a pipe mechanism, and the manipulator is responsible for accurately grasping and placing the housings from the conveying track onto the support pins 65 of the buffer jig 6. A finished product conveying mechanism: located on the other side of the press-fitting position, is used to remove the press-fitted finished products from the buffer jig 6 and convey them to the next process. The finished product conveying mechanism can adopt a conveyor belt, a manipulator or other conveying methods. When the press-fitting is completed, the control system will control the finished product conveying mechanism to take out the finished products from the buffer jig 6 and convey them along a predetermined route.

[0046] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description.
