Description

Technical Field

[0001] This application relates to the field of grooving technology, specifically a copper needle grooving device. Background Technology

[0002] Copper is a metallic element and also a transition element. Pure copper is a soft metal with a reddish-orange metallic luster when freshly cut, while its elemental form is purplish-red. It has good ductility and high thermal and electrical conductivity, making it a commonly used material in cables and electrical / electronic components. It can also be used as a building material and can be formed into numerous alloys. In the production of copper needles, grooves need to be cut into the ends to meet manufacturing requirements.

[0003] Currently, traditional grooving devices typically use a cylinder clamping mechanism to position the steel needles and prevent the product from shifting position during the cutting process. However, the cylinder clamping mechanism needs to operate frequently, which increases the friction between the piston and the cylinder wall, leading to faster wear of the cylinder wall. Especially in the process of grooving large batches of steel needles, the sealing performance of the cylinder will decrease, thus affecting the clamping accuracy.

[0004] Therefore, it is necessary to provide a copper needle grooving device to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

When the steel needle is transferred to the grooving station, the connecting plate located at the grooving station is blocked by the roller, which drives the movable block to slide in the mounting groove, thereby fixing the copper needle tightly in the clamping cavity. In addition, when the connecting plate is disengaged from the roller, the steel needle in the clamping cavity is released from the clamping restriction. Compared with the traditional cylinder clamping mechanism, the structure is simplified, the maintenance cost is reduced and the clamping accuracy is improved.

Detailed Implementation

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] like Figure 1-7 As shown, this application provides a copper needle grooving device, including: a base 1, multiple clamping mechanisms 4 and a positioning mechanism 6. A working plate 3 is rotatably connected to the top of the base 1. The working plate 3 has an installation groove, and a semi-circular hole 8 is formed in the inner wall of the installation groove. A grooving mechanism 2 for grooving copper needles is installed on the top of the base 1. The clamping mechanism 4 includes a movable block 41, which is slidably installed in the installation groove. A semi-circular groove is formed on one side of the movable block 41, which combines with the semi-circular hole 8 to form a clamping cavity. A connecting plate 42 is installed on one side of the movable block 41. 2 can be fixed to one side of the movable block 41 by bolts. The working plate 3 is also provided with a reserved slot for providing space for the connecting plate 42. The positioning mechanism 6 includes a support plate 61 installed on the top of the base 1. The support plate 61 can be fixed to the top of the base 1 by bolts. A connecting rod 62 is installed on one side of the support plate 61. The connecting rod 62 is also fixed to one side of the support plate 61 by bolts. A roller 63 is installed at the end of the connecting rod 62. The base 1 is also equipped with a drive mechanism 5 for driving the working plate 3 to rotate at an angle.

[0032] In this embodiment, the solution is a device for grooving the ends of steel needles to meet manufacturing needs. Preferably, there are three clamping mechanisms 4, and the working disc 3 has a loading station, a grooving station, and a unloading station. The grooving mechanism 2 and the positioning mechanism 6 are located on one side of the grooving station. The working disc 3 is driven by a driving mechanism 5 to rotate intermittently by 120°. The steel needle to be grooved can be placed in the clamping cavity at the loading station. As the working disc 3 rotates intermittently by 120°, the steel needle will be transferred. At the grooving station, the connecting plate 42 located at the grooving station is blocked by the roller 63, which drives the movable block 41 to slide in the mounting groove, thereby firmly fixing the copper needle in the clamping cavity. Then, the grooving mechanism 2 at the cutting station performs grooving operation on the clamped steel needle. After the grooving is completed, the working plate 3 rotates 120° again to transfer the grooved steel needle to the unloading station. When the connecting plate 42 and the roller 63 are no longer in contact, the steel needle in the clamping cavity is released from the clamping restriction, which facilitates the subsequent unloading work.

[0033] It should be noted that loading and unloading robotic arms can be installed at the loading and unloading stations respectively to complete the loading and unloading operations of copper needles, thus achieving fully automated grooving operation in conjunction with this equipment.

[0034] like Figure 7 As shown, the connecting plate 42 is composed of a horizontal plate and an arc-shaped plate, with the horizontal plate and the arc-shaped plate set at an angle.

[0035] In this embodiment, the arc plate and the working plate 3 are arranged in concentric circles to ensure that the connecting plate 42 and the connecting rod 62 at the grooving station abut against each other and can clamp the steel needle in the clamping cavity to prevent the product from changing position during the cutting process.

[0036] like Figure 7 As shown, the clamping mechanism 4 also includes a spring 43, which is installed between the working plate 3 and the connecting plate 42. The two ends of the spring 43 are fixedly connected to the outer wall of the working plate 3 and the inner wall of the arc plate in the connecting plate 42, respectively.

[0037] In this embodiment, the spring 43 can apply a reset force to the connecting plate 42. When the connecting plate 42 abuts against the roller 63, the connecting plate 42 is displaced and the spring 43 is compressed, causing the movable block 41 to move in the mounting groove, thereby clamping the steel needle. When the connecting plate 42 is disengaged from the roller 63, the spring 43 uses its own elasticity to reset the connecting plate 42, thereby releasing the clamping of the steel needle.

[0038] like Figure 5As shown, a rotating shaft 7 is installed at the bottom of the working disc 3. The rotating shaft 7 is fixed to the bottom of the working disc 3 by bolts. The rotating shaft 7 is rotatably connected to the top of the base 1. The drive mechanism 5 includes a second motor 51 and a driven gear 53. The second motor 51 is fixedly installed to the top of the base 1 by bolts. The driven gear 53 is fixedly sleeved on the outer wall of the rotating shaft 7. The output end of the second motor 51 is keyed to a drive gear 52 that meshes with the driven gear 53.

[0039] In this embodiment, the second motor 51 controls the drive gear 52 to rotate. Under the meshing connection of the drive gear 52 and the driven gear 53, the rotating shaft 7 and the top working plate 3 can be driven to rotate, thereby realizing the intermittent 120° rotation of the working plate 3. This allows the steel needles fed at the feeding station to be transferred sequentially to the grooving station and the unloading station for grooving and unloading of the steel needles.

[0040] like Figure 3-4 As shown, the grooving mechanism 2 includes a Z-shaped plate 23 and a lifting source that drives the Z-shaped plate 23 to move vertically. The top of the Z-shaped plate 23 is bolted to a first motor 24 and a mounting box 25. A milling cutter 26 is rotatably connected to one side of the mounting box 25, and a second pulley 210 coaxially arranged with the milling cutter 26 is mounted on the other side of the mounting box 25. The output end of the first motor 24 is keyed to a first pulley 29, and the first pulley 29 and the second pulley 210 are connected by belt drive.

[0041] In this embodiment, the first motor 24 controls the first pulley 29 to rotate, which in turn drives the second pulley 210 to rotate under the transmission of the belt, thereby driving the coaxially arranged milling cutter 26 to rotate, so that the high-speed operating milling cutter 26 performs a grooving operation on the end of the steel needle.

[0042] like Figure 3-4 As shown, the lifting source includes an L-shaped plate 21 and a first cylinder 22. The L-shaped plate 21 is bolted to the top of the base 1, and the first cylinder 22 is also bolted to the L-shaped plate 21. The output end of the first cylinder 22 is connected to the bottom of the Z-shaped plate 23 by a key.

[0043] In this embodiment, the first cylinder 22 can control the Z-shaped plate 23 to move vertically, thereby driving the milling cutter 26 to move synchronously, and thus controlling the downward cutting depth of the milling cutter 26.

[0044] like Figure 3-4 As shown, a slider is installed on one side of the Z-shaped plate 23 by welding, and a groove is opened on one side of the L-shaped plate 21, with the slider and the groove being slidably connected.

[0045] In this embodiment, by setting the slider and the groove, the movement trajectory of the Z-shaped plate 23 can be restricted, making the vertical movement of the Z-shaped plate 23 more stable.

[0046] like Figure 3-4 As shown, a protective cover 27 can be welded to one side of the mounting box 25, and the protective cover 27 covers the outside of the milling cutter 26.

[0047] In this embodiment, the protective cover 27 can block the debris generated during the steel needle grooving process, thus providing protection.

[0048] like Figure 4 As shown, the grooving mechanism 2 also includes a buffer 28, which includes a mounting block 281. The mounting block 281 is bolted to one side of the L-shaped plate 21, and a damper 283 is mounted on the top of the mounting block 281. A connecting block 284 is mounted on the end of the damper 283 away from the mounting block 281. A buffer spring 282 is sleeved around the damper 283, and the two ends of the buffer spring 282 are connected to the connecting block 284 and the mounting block 281, respectively.

[0049] In this embodiment, with the buffer 28, after the milling cutter 26 cuts downwards for a certain distance, the Z-shaped plate 23 can abut against the connecting block 284. When the milling cutter 26 continues to move downwards, the Z-shaped plate 23 synchronously drives the connecting block 284 to move downwards, thereby compressing the damper 283 and the buffer spring 282, achieving an effective buffering effect, so that the milling cutter 26 cuts the latter half slowly, preventing the steel needle from breaking due to cutting too fast.

[0050] Working principle:

[0051] The steel needle to be slotted is placed in the clamping mechanism 4 of the feeding station on the working plate 3. In this design, there are three clamping mechanisms 4, corresponding to the loading station, the grooving station, and the unloading station, respectively. The working plate 3 is driven by the driving mechanism 5 to rotate intermittently by 120°, so that the steel needle passes through the three stations in sequence. The steel needle can be loaded at the loading station. When the clamping mechanism 4 containing the steel needle rotates to the grooving station, it is ready to perform the grooving operation. At the grooving station, the connecting plate 42 is blocked by the roller 63, which drives the movable block 41 to slide in the mounting groove, thereby firmly fixing the steel needle in the clamping cavity. The grooving mechanism 2 is located on one side of the grooving station and performs the grooving operation on the clamped steel needle. After the grooving is completed, the working plate 3 rotates 120° again to transfer the grooved steel needle to the unloading station. During this process, when the connecting plate 42 and the roller 63 disengage, the steel needle in the clamping cavity is released from the clamping restriction, which facilitates the subsequent unloading work. Finally, the grooved steel needle is transferred to the unloading station for unloading.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
