Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0021] This utility model proposes a multi-station turntable device 100, which works in conjunction with a welding robot to complete the welding process of the workpiece.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, the multi-station turntable device 100 includes a frame 10, a turntable 20, a baffle plate 30, a power unit 40, and positioning fixtures 50. The turntable 20 is horizontally rotatable and mounted on the top of the frame 10. The baffle plate 30 is vertically mounted on the top of the turntable 20, dividing the turntable 20 into two sides, one side being a loading / unloading station and the other side being a welding station. The power unit 40 is mounted on the frame 10 and has an output shaft connected to the turntable 20. The power unit 40 drives the turntable 20 to rotate 180° in a single rotation to achieve station switching. There are multiple positioning fixtures 50, which are respectively mounted on the loading / unloading station and the welding station.

[0024] Understandably, this utility model works in conjunction with a welding robot to complete the welding process. The welding robot is located on one side of the welding station, while the operator is located on the other side of the loading and unloading station. That is, the operator only needs to complete the loading and unloading processes of the workpiece. Moreover, the loading and unloading station and the welding station are located on different sides. While the operator is loading or unloading, the welding robot on the other side can simultaneously weld the workpiece located at the welding station. This reduces labor intensity and improves welding efficiency.

[0025] In this invention, the turntable 20 serves to support multiple positioning fixtures 50. These fixtures 50 are detachably connected to the turntable 20 for easy replacement and maintenance. The number of positioning fixtures 50 at the loading / unloading station is the same as the number at the welding station. The turntable 20 is driven by a power device 40 to rotate horizontally. The power device 40 drives the turntable 20 to rotate 180° in a single rotation. This means that workpieces positioned at the loading / unloading station rotate horizontally to the welding station to await welding, and workpieces at the welding station rotate horizontally to the loading / unloading station to await unloading and the next loading cycle. This coordinated operation improves overall efficiency. The baffle 30 is vertically positioned between the loading / unloading station and the welding station, providing protection for workers during operation by preventing spatter and light from affecting them and reducing safety hazards. The baffle 30 is also detachably connected to the turntable 20 using threaded fasteners.

[0026] The workpiece to be welded according to this utility model consists of four parts, such as... Figure 8 and Figure 9 As shown, there is one part A, two parts B, and one part C. Part A is shell-shaped, the two parts B are plate-shaped and symmetrically arranged on opposite inner sides of part A, and part C is block-shaped and located at the bottom of part A, between the two parts B. Figure 6 As shown, the positioning fixture 50 of this utility model can position parts A, B and C in their respective positions to facilitate the welding process.

[0027] This utility model technical solution includes a frame 10, a turntable 20, a baffle plate 30, a power unit 40, and a positioning fixture 50. The baffle plate 30 is vertically arranged in the middle of the turntable 20 and divides the turntable 20 into two sides, namely a loading / unloading station and a welding station. The operator is located on one side of the loading / unloading station, and the welding robot used for welding is located on the other side of the welding station. Because the technical means of switching between the station is achieved by cooperating with the welding robot and using the power unit 40 to drive the turntable 20 to rotate, the technical problem of high labor intensity and low efficiency in the prior art, which is all operated manually, is effectively solved, thereby achieving the technical effect of reducing labor intensity and improving welding efficiency.

[0028] In embodiments of this utility model, such as Figure 3 As shown, the power unit 40 includes a drive cylinder 41, a transmission rack 42, and a transmission gear 43. The drive cylinder 41 is mounted on the frame 10 and has a first piston rod. The transmission rack 42 is mounted on the first piston rod. The transmission gear 43 is mounted on the output shaft and meshes with the transmission rack 42. The drive cylinder 41 drives the transmission gear 43 to move, thereby causing the transmission gear 43, the output shaft, and the turntable 20 to rotate synchronously.

[0029] The drive cylinder 41 of this invention is mounted on the bottom of the turntable 20 via a cylinder support. The cylinder support can be detachably or non-detachably connected to the turntable 20. When the first piston rod of the drive cylinder 41 extends or retracts, its pushing force is transmitted to the transmission rack 42, thereby realizing the rotation of the transmission gear 43. The rotation of the transmission gear 43 drives the output shaft and the turntable 20 to rotate synchronously. In this invention, when the first piston rod extends, the turntable 20 rotates 180° horizontally in a first direction; when the first piston rod retracts, it rotates 180° horizontally in a second direction. The first and second directions are opposite directions; the first direction can be clockwise and the second direction counterclockwise, or vice versa. The turntable 20 achieves workstation switching by rotating 180° in a single rotation. This invention uses a rack and pinion transmission method, which has the characteristics of high power, high precision, and high efficiency.

[0030] In embodiments of this utility model, such as Figure 3 As shown, one side of the transmission rack 42 is the meshing tooth surface, and the other side of the transmission rack 42 is the guide plane. The power unit 40 also includes a guide bearing 44, which is located on the frame 10 and spaced apart from the transmission gear 43. The guide bearing 44 is provided with a guide groove, the meshing tooth surface meshes with the transmission gear 43, and the guide plane rolls with the guide groove.

[0031] In this invention, the spaced transmission gears 43 and guide bearings 44 can guide the movement of the transmission rack 42, ensuring that the transmission rack 42 moves back and forth between them. This can prevent the transmission rack 42 from disengaging from the meshing tooth surface, thus affecting the rotation angle of the turntable 20. At the same time, the cooperation between the guide bearings 44 and the transmission rack 42 can also increase the guiding accuracy and reduce the friction during the movement.

[0032] In embodiments of this utility model, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the positioning fixture 50 includes limiting posts 51 and limiting brackets 52. The limiting posts 51 are used for positioning the four corners of the workpiece to be welded. There are four limiting posts 51 and they are located on the turntable 20. The limiting brackets 52 are used for limiting the workpiece to be welded. The limiting brackets 52 are located on the turntable 20.

[0033] Part A has positioning holes at its four corners. Four positioning posts 51 are used to position part A, each corresponding to one of the four corners. Each positioning post 51 has a protruding positioning protrusion at its top, the shape of which matches the positioning hole. The protrusion passes through the positioning hole to position part A. Simultaneously, the top of the positioning post 51 contacts the bottom of part A, providing some support. A positioning bracket 52 is used to position two parts B. Part C is block-shaped and is placed on part A at the welding position.

[0034] In an embodiment of this utility model, the limiting bracket 52 is provided with a slot.

[0035] like Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, part B of this invention is plate-shaped. To prevent part B from tipping over during the rotation of the turntable 20, which would affect the welding effect, this invention provides a slot for positioning part B on the limiting bracket 52. The width of the slot is adapted to the thickness of part B. The limiting bracket 52 is U-shaped and includes a base and two locking parts located above the base. The locking parts have a slot on the side facing the workpiece. During the workpiece loading process, part B is manually positioned in the slot, thus ensuring that part B will not tip over due to the rapid rotation of the turntable 20 and that part B adheres to the position of part A to be welded during the welding process, improving the welding quality.

[0036] In embodiments of this utility model, such as Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the positioning fixture 50 also includes a material ejection assembly 53, which includes a material ejection cylinder 531 and a material ejection plate 532. The material ejection cylinder 531 is located at the bottom of the turntable 20 and is provided with a second piston rod. The material ejection plate 532 is located at the top of the turntable 20, and the second piston rod passes through the turntable 20 and is connected to the material ejection plate 532.

[0037] In this utility model, when the second piston rod of the ejector cylinder 531 extends, it drives the ejector plate 532 to move upward synchronously, lifting the welded workpiece upward to achieve ejection. When the second piston rod of the ejector cylinder 531 retracts, it drives the ejector plate 532 to move downward synchronously, which plays a role in avoiding the workpiece to be welded. When the second piston rod retracts, there is a gap or just contact between the ejector plate 532 and the bottom of part A. If the ejector plate 532 contacts the bottom of part A, the ejector plate 532 also has the function of supporting the workpiece to be welded.

[0038] In an embodiment of this utility model, the unloading assembly 53 further includes a guide post disposed on the turntable 20. The unloading plate 532 is provided with a guide hole, and the unloading plate 532 slides up and down with the guide post through the guide hole. Through the guiding effect of the guide hole and the guide post, the unloading plate 532 can move up and down in a specific direction.

[0039] In embodiments of this utility model, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the multi-station turntable device 100 also includes a clamping assembly 60. The number of positioning fixtures 50 is defined as 2n, and the number of clamping assemblies 60 is n. The clamping assembly 60 is located between two positioning fixtures 50 and is used to simultaneously clamp two workpieces to be welded. The clamping assembly 60 of this invention is used to clamp part C, ensuring that part C does not shift position during movement and welding.

[0040] In embodiments of this utility model, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the clamping assembly 60 includes a corner cylinder 61, a limiting seat 62, and a clamping plate 63. The corner cylinder 61 is located at the bottom of the turntable 20 and has a third piston rod. The limiting seat 62 is located at the top of the turntable 20 and corresponds to the position of the corner cylinder 61. The clamping plate 63 is located at the top of the limiting seat 62. The third piston rod passes through the turntable 20 and the limiting seat 62 in sequence and is connected to the clamping plate 63.

[0041] Understandably, the angle cylinder 61 has vertical movement and horizontal rotation. The angle cylinder 61 used in this invention can rotate 180° horizontally. The two ends of the clamping plate 63 are clamping ends, corresponding to the parts C placed on the two positioning fixtures 50 respectively. When clamping is required, the angle cylinder 61 drives the third piston rod to rotate 180° so that the clamping end corresponds vertically to the part C. Subsequently, the angle cylinder 61 drives the third piston rod to move downwards, so that the clamping end of the clamping plate 63 clamps the part C; this state is the clamping state. When unloading is required, the angle cylinder 61 drives the third piston rod to move upwards, so that the clamping end of the clamping plate 63 moves away from the part C. Subsequently, the angle cylinder 61 drives the third piston rod to rotate 180° in the opposite direction. The clamping plate 63, after rotation, is positioned between the two positioning fixtures 50; this state is the released state. The clamping plate 63 serves to avoid the welded workpiece, facilitating unloading.

[0042] In this invention, the clamping plate 63 not only clamps part C, but also clamps and positions part B. That is, while the clamping end clamps part C, the clamping end is also in close contact with the top of part B, reducing shaking during the welding process and improving welding accuracy.

[0043] In embodiments of this utility model, such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a limiting groove is provided on the top of the limiting seat 62, and a limiting part with the same shape as the limiting groove is provided on the clamping plate 63. When the clamping assembly 60 is in the clamping state, the limiting part is engaged in the limiting groove. Through the limiting effect of the limiting part and the limiting groove, the clamping plate 63 can be prevented from rotating during the welding process, thereby affecting the welding accuracy.

[0044] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
