Description

Technical Field

[0001] This invention relates to the field of terminal crimping machine technology, and more particularly to an adjustable stroke terminal crimping machine. Background Technology

[0002] In electrical engineering, a terminal refers to a wiring terminal, also known as a wire terminal block. These terminals come in various forms, including single-hole, double-hole, socket, and hook types, and are made from a variety of materials, such as silver-plated copper, zinc-plated copper, copper, aluminum, and iron. Their main function is to transmit electrical signals or conduct electricity. The production process of terminals typically includes metal stamping and injection molding. Terminal stamping refers to applying pressure to a metal sheet using stamping equipment and molds, causing it to undergo plastic deformation to obtain terminal products of the required shape and size.

[0003] The commonly used terminal stamping equipment is the terminal crimping machine, in which the stamping head is the core stamping component. Because the stamping stroke of the existing terminal crimping machine's stamping head is fixed, the terminal crimping machine is only suitable for stamping a single type of terminal. When the specifications of the stamped terminals are different, the terminal crimping machine needs to manually adjust the stamping stroke. This process is not only cumbersome but also leads to low stamping efficiency. The use of the terminal crimping machine is always limited, which has an adverse impact on production. Therefore, further improvements to the terminal crimping machine are needed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an adjustable stroke terminal machine, which features automatic adjustment of the stamping stroke.

The stamping device includes a stamping motor, a slider, and a stamping head connected in sequence. The stamping motor drives the stamping head to move up and down via the slider. The base is also equipped with an adjustment device for adjusting the stamping stroke of the stamping head. The adjustment device includes an adjustment motor and a drive shaft connected to the adjustment motor. The drive shaft is telescopically connected to the stamping head and can drive the stamping head to rotate. The stamping head is threadedly connected to the slider.

[0006] Optionally, the stamping motor and the adjusting motor are arranged perpendicular to each other, and an eccentric roller is also included. The stamping motor is connected to the slider through the eccentric roller.

[0007] Optionally, the eccentric roller includes a roller body and an eccentric wheel disposed at the front end of the roller body. The roller body is connected to a stamping motor, and the eccentric wheel is connected to a slider.

DETAILED DESCRIPTION

[0025] The application will be described in detail below with reference to the accompanying drawings Figures 1 to 6 The application will be described in detail below with reference to the accompanying drawings

[0026] The application is a terminal machine with adjustable stroke, which comprises a frame 1, a stamping device 2 installed on the frame 1, the stamping device 2 comprising a stamping motor 21, a sliding block 22 and a stamping head 23 connected in sequence, the stamping motor 21 driving the stamping head 23 to move up and down along the frame 1 to stamp the terminal through the sliding block 22; the frame 1 is also provided with an adjusting device 3 for adjusting the stamping stroke of the stamping head 23; here, the stamping stroke refers to the longest distance between the stamping head 23 and the terminal in a single stamping process, that is, the height from the terminal when the stamping head 23 is at the topmost stamping position; in this technical solution, the adjusting device 3 comprises an adjusting motor 31 and a driving shaft 32 in transmission connection with the adjusting motor 31, the driving shaft 32 being in telescopic connection with the stamping head 23 and the driving shaft 32 being able to drive the stamping head 23 to rotate, and the stamping head 23 being in threaded connection with the sliding block 22. The principle of use of the adjusting device 3 is that when the adjusting motor 31 is started, the driving shaft 32 rotates to drive the stamping head 23 to rotate, and since the stamping head 23 is in threaded connection with the sliding block 22, the stamping head 23 will produce a lifting displacement in the interior of the sliding block 22 while rotating, so as to achieve the purpose of adjusting the stamping stroke of the stamping head 23, and the adjusting process will not interfere with the stamping process of the terminal machine, and the technical effect of independent stamping and adjusting can be achieved.

[0027] The terminal machine of the application can automatically adjust the stamping stroke of the stamping head 23 without affecting the stamping process through ingenious structural design, so that the terminal machine is no longer limited to stamping a single type of terminal, and the stamping stroke can be adjusted at any time according to the specifications of the stamped terminal, which significantly expands the application range of the terminal machine, is more conducive to production, and simplifies the stamping process of the terminal.

[0028] In this technical solution, the stamping motor 21 and the adjusting motor 31 are arranged perpendicularly to each other, and an eccentric roller 4 is further included, the stamping motor 21 being in transmission connection with the sliding block 22 through the eccentric roller 4. Figure 2As shown, the power of the motor is transmitted to the slider 22 through the eccentric roller 4, which can drive the slider 22 to have higher punching force during the lifting process, thereby ensuring that the terminal machine can be stably formed every time and improving the yield of the punching.

[0029] As an embodiment, the eccentric roller 4 comprises a roller body 41 connected to the punching motor 21 and an eccentric wheel 42 arranged at the front end of the roller body 41, and the eccentric wheel 42 is connected to the slider 22.

[0030] As preferred, the slider 22 is provided with a transverse sliding groove 221 on one side, the transverse sliding groove 221 accommodates the eccentric wheel 42, and the transverse sliding groove 221 is slidingly connected to the eccentric wheel 42. When the eccentric wheel 42 is driven to rotate circumferentially by the punching motor 21, the transverse sliding groove 221 can provide sufficient space for the eccentric wheel 42 to move, so that the adjusting motor 31 can stably drive the slider 22 to move up and down along the base 1 to complete the punching process.

[0031] As another embodiment, the eccentric wheel 42 is movably sleeved with a movable block 421 at the outer end, and the movable block 421 is slidingly connected to the transverse sliding groove 221. The additional movable block 421 can make the connection between the eccentric wheel 42 and the slider 22 more stable and the movement more stable.

[0032] As preferred, the base 1 is also provided with a longitudinal sliding groove 11, and the slider 22 is slidingly connected to the longitudinal sliding groove 11. The longitudinal sliding groove 11 limits the movement of the slider 22 to avoid deviation and punching errors during the up-and-down movement.

[0033] In the technical solution, the top of the punching head 23 is fixedly provided with a connecting column 231, and the driving shaft 32 is hollow and sleeved outside the connecting column 231. In order to stably install the punching head 23 in the slider 22, the outer wall of the punching head 23 is provided with external threads connected to the slider 22, and the inner wall of the slider 22 is provided with internal threads matched with the external threads.

[0034] In order to make the driving shaft 32 not affect the punching action and drive the punching head 23 to rotate, the inner wall of the driving shaft 32 is provided with a limiting portion 321, and the outer wall of the connecting column 231 is provided with a flat portion 232 matched with the limiting portion 321. When the driving shaft 32 is sleeved outside the connecting column 231, the limiting portion 321 just abuts against the flat portion 232, and the driving shaft 32 laterally clamps the connecting column 231, so that the connecting column 231 cannot rotate in the driving shaft 32 but can perform telescopic movement, which is the key reason why the punching process and the adjusting process can be performed at the same time.

[0035] Preferably, the driving shaft 32 extends into the slider 22, and the driving shaft 32 is movably connected with the slider 22, so that the driving shaft 32 does not affect the movement of the slider 22 even if it drives the punch head 23 to rotate, and the structure can further compact the terminal machine structure and shorten the overall volume of the terminal machine.

[0036] The above merely illustrates the preferred embodiments of the present application, and for those skilled in the art, the specific implementation and application scope can be changed according to the idea of the present application, and the content of the description should not be understood as a limitation of the present application.
