Description

Technical Field

[0001] The utility model relates to the technical field of terminal riveting, and more particularly to an automatic adjustment mechanism for the height of terminal riveting. Background Art

[0002] Terminals are the components that connect batteries to external conductors. In electrical engineering, terminals generally refer to wiring terminals, also known as terminal blocks. They come in various types, including single-hole, double-hole, socket, and hook. During the riveting process, when changing the terminal type, it is necessary to measure with a micrometer, calculate the error between the measured value and the required value, and adjust the terminal riveting height accordingly. However, manual calculation, adjustment, or input carries the risk of miscalculation or adjustment errors, resulting in over-riveting or under-riveting, and even the potential safety hazard of die blades breaking and flying. Therefore, we propose an automatic terminal riveting height adjustment mechanism. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The utility model does not change the stroke of the driving module and the movable design of the riveting platform, and the cooperation of the bidirectional lead screw and the lead screw nut can drive the traction plate to move synchronously, and further enables the connecting plate to drive the riveting platform to move up and down.

[0020] like Figures 1 to 4 As shown, the utility model relates to an automatic adjustment mechanism for the riveting height of a terminal, comprising a shell 1, and a data transmission group 4 is provided on the upper half of the shell 1. The data transmission group 4 can be connected to an external control system or can be installed with a control structure for regulation. A driving module 3 is provided below the data transmission group 4. The driving module 3 can be selected as a cylinder or a hydraulic rod according to the situation. The driving module 3 is connected to a test module 2, and the test module 2 is composed of a pressure measuring block 201 and a test connecting rod 202. A contact sensor is provided on the pressure measuring block 201. Unlike the prior art, the stroke length of the driving module 3 remains unchanged, and a riveting platform 5 is provided in the bottom area of ​​the shell 1. The riveting platform 5 can be moved in a height position. By changing the height of the riveting platform 5, automatic height adjustment is achieved, thereby avoiding manual adjustment input and the possibility of errors. Since the driving stroke remains unchanged, there will be no risk of excessive riveting or light riveting, and there will even be a safety hazard of the mold blade breaking and flying out.

[0021] Since the existing riveting equipment has limited space, in order to reduce the occupied space, the existing cylinder, hydraulic rod and other equipment are not used to drive the riveting platform 5 to rise and fall. Instead, a lifting unit 6 is set at the bottom of the riveting platform 5. The lifting unit 6 includes a bidirectional screw rod 601, and the bidirectional screw rod 601 is fixed in position by a pillow bearing. One end of the bidirectional screw rod 601 is connected to a driving motor 8, and screw nuts 602 are symmetrically sleeved on both ends of the outer periphery of the bidirectional screw rod 601. The screw nuts 602 are connected to the bottom of the shell 1 in a limited sliding connection. The limited sliding connection is achieved by a protrusion and a sliding groove to prevent the screw nuts 602 from rotating. A connecting plate 603 is provided above the bidirectional screw rod 601, and the top of the connecting plate 603 is fixed to the bottom of the riveting platform 5. A traction plate 604 is provided on both sides of the connecting plate 603 and between the two screw nuts 602. The traction plate 604 is movably connected in a hinged manner, and the driving motor 8 is electrically connected to the driving module 3 and the data transmission group 4;

[0022] Working principle: It mainly adopts the riveting sample mold. When adjustment is needed, the connecting plate 603 is first driven by the riveting platform 5 to drop to the lowest point, the driving module 3 is expanded to the maximum stroke, and then the riveting sample mold matching the production is placed. The external control structure or data transmission group 4 controls the drive motor 8 to operate, so that the bidirectional screw 601 rotates, and the screw nut 602 and the traction plate 604 move synchronously, so that the connecting plate 603 rises. When the riveting sample mold rises and reaches the position of the contact sensor, it stops running after contact, completing the height positioning of the riveting platform 5, and the driving module 3 retracts again. The overall adjustment process does not change the riveting height of the driving module 3. The traction plate 604 is a curved, folded and lifting design, and the overall design is along the bottom, which greatly reduces the occupied space. Because the screw nuts 602 and the traction plate 604 on both sides are symmetrically distributed, an isosceles trapezoidal force structure is formed as a whole, and its lifting stability is guaranteed.

[0023] Furthermore, the riveting platform 5 is supported only by the connecting plate 603, and its support stability is poor. To address this issue, stabilizing units 7 are further provided on both sides of the bottom of the riveting platform 5. The stabilizing unit 7 includes a driven worm gear 701 and a driven worm 702 that are meshed with each other. A driving worm 9 fixed to the bidirectional screw 601 is meshed on the outer side of the driven worm gear 701. The center of the driven worm gear 701 is rotatably connected to the bottom of the housing 1. The center of the driven worm 702 is connected to a long rod 703. A plurality of support blocks 74 are provided on the periphery of the long rod 703. The support block 74 consists of a round block 741 and a spiral arc block 742. The round block 741 is fixed to the long rod 703. The spiral arc block 742 is a structural design with a gradually increasing curvature. A plurality of through holes for the spiral arc block 742 to rotate are provided at the bottom of the housing 1. The spiral arc block 742 is always in contact with and supports the bottom of the riveting platform 5 when rotating with the long rod 703.

[0024] It should be noted that the different rotation speeds of the driven worm wheel 701 and the driven worm 702 are cleverly utilized here to achieve differential speed, so that the speed at which the long rod 703 drives the spiral arc block 742 to rotate corresponds to the speed at which the connecting plate 603 is lifted and lowered, so that the arc surface of the spiral arc block 742 can always contact and support the bottom of the connecting plate 603, achieving a supporting effect during the lifting process and before and after the process, thereby greatly improving stability.

[0025] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
