Description

Technical Field

[0001] This utility model relates to the field of welding wire production and packaging technology, specifically a multi-station turntable device. Background Technology

[0002] The metal welding wire spool with a center hole used for finished welding wire packaging consists of various numbers of outer rings, inner rings, spokes, and transverse ribs. In the manufacturing process of the metal welding wire spool with a center hole, the outer rings, inner rings, and spokes need to be welded into side ring assemblies first. Finally, the two side ring assemblies and the transverse ribs are welded together to form a complete welding wire spool. The side ring assembly consists of one outer ring, one inner ring, and eight evenly distributed spokes. Its manufacturing process requires four steps: inner ring and outer ring feeding, spoke feeding, welding, and unloading. From the side ring assembly to the finished metal welding wire spool, four steps are required: side ring feeding, transverse rib feeding, welding, and unloading. Most turntable devices on the market are single-station, so their efficiency is low and their space utilization is poor. Utility Model Content

[0003] This invention addresses the problems of low efficiency and poor space utilization in the production of side ring components and the subsequent production of metal welding wire spools. It proposes a multi-station turntable device to streamline and integrate the production line, thereby improving space utilization and production efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

One end of the gear shaft is connected to the pallet, and the other end of the gear shaft passes through the turntable and is connected to the planetary gear. A bearing A is provided between the gear shaft and the turntable.

[0007] An internal gear ring is connected to the turntable via multiple rollers. The internal gear ring is arranged concentrically with the turntable and meshes with the planetary gears of each tray assembly.

[0008] Motor A is mounted on the side of the support plate via a motor mount, and a motor gear that meshes with an internal gear ring is provided on the output shaft of motor A.

[0009] A bearing housing A is installed at the center of the turntable, and a bearing B is arranged inside the bearing housing A. The outer pressure cover is connected to the bearing housing A and fixed to the outer ring of the bearing B. The inner ring of the bearing B is provided with a bearing housing B fixed by the inner pressure cover.

[0010] Motor B is mounted on the support plate. The output shaft of motor B passes through bearing housing B and is connected to the turntable. Bearing housing B is fixedly connected to the support plate.

[0011] Preferably, each roller has a V-shaped concave groove on its surface, and the outer surface of the internal gear ring has a V-shaped convex groove that mates with the V-shaped concave groove of the roller. The number of V-shaped convex grooves is the same as the number of rollers.

[0012] Preferably, the plurality of rollers are evenly installed on the turntable at equal angles with the center of the turntable as the center.

Detailed Implementation

[0021] The present invention will be described in detail below with reference to the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a multi-station turntable device, including a support plate 7, a motor A4, a motor B8 and a turntable 2. The turntable 2 is provided with 2 to 6 stations, and each station is provided with a tray assembly. Preferably, multiple tray assemblies are evenly installed on the turntable 2 at equal angles with the center of the turntable 2 as the center. In the production of the side ring, when one station is feeding the inner and outer rings, other stations can feed, weld or unload the spokes. In the production of the metal welding wire spool from the side ring assembly, when one station is feeding the side ring assembly, other stations can feed, weld or unload the transverse ribs.

[0023] Each pallet assembly includes a pallet 1, a gear shaft 12, and a planetary gear 11 fixed on a turntable 2. One end of the gear shaft 12 is connected to the pallet 1, and the other end of the gear shaft 12 passes through the turntable 2 and is connected to the planetary gear 11. A bearing A13 is provided between the gear shaft 12 and the turntable 2.

[0024] The turntable 2 is connected to an internal gear ring 6 via multiple rollers 3. The internal gear ring 6 is arranged concentrically with the turntable 2, and the internal gear ring 2 meshes with the planetary gear 11 of each tray assembly.

[0025] Motor A4 is mounted on the side of support plate 7 via motor base 5. Motor gear 14 that meshes with internal gear ring 6 is provided on the output shaft of motor A4. Motor A4 drives tray 1 and planetary gear 11 to rotate through the cooperation of motor gear 14 and internal gear ring 6.

[0026] A bearing housing A10 is installed at the center of the turntable 2. The bearing B17 is arranged inside the bearing housing A10. The outer pressure cover 9 is connected to the bearing housing A10 and fixed to the outer ring of the bearing B17. The inner ring of the bearing B17 is provided with a bearing housing B16 fixed by the inner pressure cover 15.

[0027] Motor B8 is mounted on support plate 7. The output shaft of motor B8 passes through bearing housing B16 and is connected to turntable 2. Bearing housing B16 is fixedly connected to support plate 7.

[0028] Motor A4, motor mount 5, support plate 7, motor B8, inner pressure cover 15, and bearing seat B16 are fixedly installed.

[0029] The tray 1, turntable 2, internal gear ring 6, outer pressure cover 9, bearing housing A10, planetary gear 11, gear shaft 12, and bearing A13 are rotatable, among which the tray 1, internal gear ring 6, planetary gear 11, and gear shaft 12 can rotate independently.

[0030] Preferably, each roller 3 is rotatable, and the surface of each roller 3 is provided with a V-shaped concave groove. The outer surface of the internal gear ring 6 is provided with a V-shaped convex groove that mates with the V-shaped concave groove of the roller 3. The number of V-shaped convex grooves is the same as the number of rollers 3. Preferably, multiple rollers 3 are evenly installed on the turntable 2 at equal angles with the center of the turntable 2 as the center. More preferably, the number of rollers 3 is 6. When the internal gear ring 6 rotates concentrically with the turntable 2, the degrees of freedom of the internal gear ring 6 in other directions are restricted.

[0031] Preferably, the turntable 2 is provided with 3 workstations, each workstation is rotatably equipped with a tray assembly, and there are 3 tray assemblies in total. In the production of side ring assemblies, when one workstation is feeding the inner and outer rings, the other workstations can feed, weld or unload the spokes, which greatly saves time and improves the production efficiency of the side ring assemblies. In the production of metal welding wire spools from the side ring assemblies, when one workstation is feeding the side ring assemblies, the other workstations can feed, weld or unload the transverse ribs, which greatly saves time and improves the production efficiency of the metal welding wire spools.

[0032] Preferably, the turntable 2 is provided with 4 workstations, each of which is rotatably equipped with a tray assembly. With 4 tray assemblies, when one workstation is feeding the inner and outer rings, the other workstations can feed, weld, or unload the spokes, which greatly saves time and improves the production efficiency of the side ring assembly. When making the metal welding wire spool from the side ring assembly, when one workstation is feeding the side ring assembly, the other workstations can feed, weld, or unload the transverse ribs, which greatly saves time and improves the production efficiency of the metal welding wire spool.

[0033] When turntable 2 has 3 workstations, motor B8 drives turntable 2 to rotate, causing pallet 1 to rotate through a certain angle. Turntable 2 rotates 120° clockwise, and pallet 1 at the top will rotate to the lower right position.

[0034] When motor B8 starts and causes turntable 2 to revolve, if motor A4 does not start, under the action of internal gear ring 6, planetary gear 11 will drive tray 1 to rotate simultaneously, and the relative position of the two will change. If motor A4 starts, by matching the speed with motor B8, it can be ensured that after each tray 1 and turntable 2 rotates 120° as a whole, the relative position of the two remains unchanged or is positioned at a specific angle. Each tray enters the next process after completing one process, and multiple stations can perform different processes simultaneously.

[0035] When motor B8 is not started, turntable 2 is in a fixed state. If motor A4 is started, tray 1 will rotate independently, which can match different process steps in this workstation.

[0036] By breaking down a process into several steps, performing one or more steps at a single workstation, and then moving to the next workstation after completion, it is beneficial to streamline and integrate the production line, improve space utilization and production efficiency.

[0037] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions and substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
