Detailed Implementation

[0028] During the manufacturing process of the water heater's inner tank, two workpieces, such as end caps, need to be joined and welded together to form the inner tank. In the assembly line production process, the workpieces are placed on a positioning plate and positioned using photoelectric sensors and positioning pins. The two positioned workpieces are then joined and welded together, thereby improving positioning accuracy.

[0029] After positioning the workpiece, it often needs to be adjusted to a specific direction and angle, and coordinated with other structural components such as transfer structures to achieve automated assembly. In related technologies, the workpiece position is often adjusted manually based on visual inspection, such as through manual handling. However, this method is prone to safety hazards such as scratches and injuries from falling objects. Furthermore, the labor intensity for operators is high, and the consistency of adjustment quality varies among different operators, resulting in low yield and low production efficiency for water heater inner tanks.

[0030] To address the aforementioned technical problems, this application provides a transmission device and a welding positioning device. The transmission device is used to adjust the position of a positioned workpiece assembly. The transmission device includes a first driving component and a transmission assembly, and the first driving component and the transmission assembly are tractively connected. Thus, under the transmission force of the transmission assembly, the position of the positioned workpiece can be adjusted to a specific direction and angle, thereby achieving the effect of cooperating with other structural components. No operator intervention is required, which helps reduce the labor intensity of operators during processing, ensures operator safety, and improves the yield rate and production efficiency of water heater inner tanks.

[0031] The following is combined Figures 1 to 7 The preferred technical solutions of the transmission device and welding positioning device of the present invention are described.

Figure 2 , Figure 6 Schematic diagram of the assembly structure of the transmission component and the first driving component of the transmission device provided in the embodiment of the present invention. Figure 3 , Figure 7 This is a schematic diagram of the structure of the base of the transmission device provided in an embodiment of the present invention.

[0033] Reference Figure 1 and Figure 2 As shown, this application provides a welding positioning device 200, which may include a workpiece assembly 210, a positioning assembly 220 and a transmission device 100. The positioning assembly 220 is used to position the workpiece 212, and the transmission device 100 is used to adjust the position of the positioned workpiece 212.

[0034] Reference Figure 1 As shown, the workpiece assembly 210 may include a positioning seat 211 and a workpiece 212. The workpiece 212 is placed on the positioning seat 211, which is mounted on the transmission assembly 130. The positioning seat 211 is a basic structure that can provide an installation base for the workpiece 212 and other components.

[0035] For example, workpiece 212 may include one, two, or multiple. In this embodiment, the number of workpieces 212 is not further limited.

[0036] For example, workpiece 212 can be a columnar or cylindrical structure, or workpiece 212 can be an arc-shaped workpiece 212. In this embodiment, the positioning and assembly of the arc-shaped workpiece 212 are mainly used as an example for illustration. For example, workpiece 212 can be two arc-shaped end caps in the inner tank of a water heater.

[0037] In some embodiments, multiple limiting posts 2111 may be provided around the periphery of the positioning seat 211, for example, refer to Figure 1 and Figure 2 As shown, the limiting post 2111 includes multiple posts, which are spaced around the periphery of the positioning seat 211. In this way, when the workpiece 212 is placed on the positioning seat 211, the limiting post 2111 can limit the workpiece 212, thereby ensuring that the workpiece 212 is located on the positioning seat 211.

[0038] Reference Figure 1 and Figure 2 As shown, the positioning component 220 is disposed on the transmission device 100. The positioning component 220 may include a detection element 221, a positioning element 222, and a second driving element 223. The detection element 221 is disposed on the positioning seat 211, and the positioning element 222 and the second driving element 223 are both disposed on the base of the transmission device 100. The positioning element 222 and the second driving element 223 are connected.

[0039] For example, the second drive member 223 may be, but is not limited to, a cylinder, a hydraulic cylinder, and / or a cam mechanism. Therefore, the embodiments of this application do not limit the specific structure of the second drive member 223.

[0040] For example, the detection element 221 can be, but is not limited to, an infrared sensor. An infrared sensor is a sensor that uses infrared light to process data and has the advantages of high sensitivity. The infrared sensor does not come into direct contact with the object being measured during measurement, so there is no friction. The embodiments of this application do not limit the specific structure of the detection element 221.

[0041] For example, the positioning element 222 can be a telescopic structure. For example, the positioning element 222 can be, but is not limited to, a positioning pin with chamfered guide. The positioning pin is a part used for mechanical movement and for determining position in two-dimensional space. Positioning pins are widely used in molds to ensure accurate positioning of adjacent parts of the mold. The embodiments of this application do not limit the specific structure of the positioning element 222.

[0042] The workpiece 212 and the positioning seat 211 are rotatably connected, meaning that the workpiece 212 and the positioning seat 211 are not fixedly connected. This arrangement avoids the problem that the detection element 221 may not be able to detect the positioning hole on the workpiece 212 because the workpiece 212 is in a fixed state.

[0043] The positioning process of the positioning component 220 of the welding positioning equipment 200 provided in this application is as follows:

[0044] The workpiece 212 rotates on the positioning seat 211. When the detection element 221 senses the positioning hole on the workpiece 212, the workpiece 212 stops rotating. The positioning element 222 extends in the direction toward the workpiece 212 and is embedded in the positioning hole. The positioning element 222 calibrates and positions the positioning hole. After positioning is completed, the positioning element 222 retracts in the direction away from the workpiece 212. The positioned workpiece 212 moves from the positioning seat 211 and is transported to the position to be welded.

[0045] Repeat the above steps to position each workpiece 212 sequentially, and then transport the positioned workpieces 212 to the welding position in sequence. This positioning method ensures that the positioning holes on both workpieces 212 face a preset direction. During welding, the two workpieces 212 are welded together along the preset direction of the positioning holes, which improves the positioning accuracy of the workpieces 212, thereby improving the welding accuracy and reducing the labor intensity and difficulty of the welding process.

[0046] Reference Figure 3 As shown, the transmission device 100 may include a base 110, a first driving member 120, and a transmission assembly 130. The base 110 has a mounting platform 111 and a mounting cavity 112. The first driving member 120 and the transmission assembly 130 are both disposed in the mounting cavity 112. The transmission assembly 130 is located on the side of the first driving member 120 closer to the mounting platform 111.

[0047] During assembly, the first end of the transmission assembly 130 is connected to the first driving member 120, the second end of the transmission assembly 130 passes through the mounting platform 111, the end face of the second end of the transmission assembly 130 protrudes from the surface of the mounting platform 111, and the second end of the transmission assembly 130 is used to place the positioning seat 211.

[0048] Continue to refer to Figure 3 As shown, the first driving component 120 may include a driving housing 121, a driving motor, and a driving shaft 122 disposed in the driving housing 121. The first end of the transmission assembly 130 is connected to the driving shaft 122 in a transmission manner. The driving motor is used for extending or retracting the driving shaft 122.

[0049] For example, the first drive member 120 may be, but is not limited to, a cylinder, a hydraulic cylinder, and / or a cam mechanism. Therefore, the embodiments of this application do not limit the specific structure of the first drive member 120.

[0050] The transmission assembly 130 may include a transmission body 134 and a transmission shaft 135 disposed in the transmission body 134, the transmission shaft 135 being connected to the drive shaft 122 in a transmission manner.

[0051] For example, the transmission component 130 may be, but is not limited to, gears, axles, connecting rods, pulleys, etc. Therefore, the specific structure of the transmission component 130 is not limited in the embodiments of this application.

[0052] The transmission assembly 130 is a device for transmitting power. Specifically, in this embodiment, the transmission assembly 130 is used to receive the power of the first driving member 120 and transmit the power and motion to the workpiece 212 located on the positioning seat 211. The workpiece 212 obtains the motion power and adjusts to a specific direction and angle according to actual needs.

[0053] In this embodiment, the location, quantity, and transmission process of the transmission components 130 are not further limited. For example, the following description can be used as a reference:

[0054] In the first feasible approach, refer to Figure 4 As shown, only one transmission assembly 130 may be provided. For example, the transmission assembly 130 may only include a first transmission member 131, the first end of the first transmission member 131 being connected to the first driving member 120, the end face of the second end of the first transmission member 131 protruding from the surface of the mounting platform 111, and the second end of the first transmission member 131 being used to place the workpiece 212.

[0055] The transmission process of the transmission component 130 in this embodiment is as follows:

[0056] The drive motor drives the drive shaft 122 of the first drive member 120 to extend. The drive shaft 122 of the first drive member 120 transmits the driving power to the transmission shaft 135 of the first transmission member 131. The transmission shaft 135 rotates and transmits the power and motion to the workpiece 212 located on the positioning seat 211, thereby facilitating the lifting of the workpiece 212.

[0057] Correspondingly, the drive motor drives the drive shaft 122 of the first drive member 120 to retract, and the drive shaft 122 of the first drive member 120 transmits power to the transmission shaft 135 of the first transmission member 131. The transmission shaft 135 rotates in the opposite direction and transmits the power and motion to the workpiece 212 located on the positioning seat 211, thereby facilitating the descent of the workpiece 212.

[0058] In the second feasible approach, refer to Figure 5 As shown, the transmission assembly 130 may include two. For example, the transmission assembly 130 may include a first transmission member 131 and a second transmission member 132 spaced apart, with the first drive member 120 disposed close to the second transmission member 132 and located on the side of the second transmission member 132 facing away from the mounting platform 111.

[0059] The first end of the second transmission member 132 is connected to the first driving member 120, and the external teeth on the second end of the second transmission member 132 mesh with the external teeth on the first end of the first transmission member 131. The end faces of the second ends of the first transmission member 131 and the second ends of the second transmission member 132 both protrude from the surface of the mounting platform 111, and the second end of the first transmission member 131 is used to place the workpiece assembly 210.

[0060] The transmission process of the transmission component 130 in this embodiment is as follows:

[0061] The drive motor drives the drive shaft 122 of the first drive member 120 to extend. The drive shaft 122 transmits the driving power to the drive shaft 135 of the second transmission member 132. The drive shaft 135 of the second transmission member 132 transmits the power to the drive shaft 135 of the first transmission member 131. The drive shaft 135 of the first transmission member 131 rotates and transmits the power and motion to the workpiece 212, thereby facilitating the positional movement of the workpiece 212, such as the workpiece 212 rising, moving to the left, or rotating in a clockwise direction.

[0062] Correspondingly, the drive motor drives the drive shaft 122 of the first drive member 120 to retract, and the drive shaft 122 transmits power to the drive shaft 135 of the second transmission member 132. The drive shaft 135 of the second transmission member 132 transmits the power to the drive shaft 135 of the first transmission member 131. The drive shaft 135 of the first transmission member 131 rotates in the opposite direction and transmits the power and motion to the workpiece 212 located on the positioning seat 211, thereby facilitating the positional movement of the workpiece 212, such as the workpiece 212 descending, moving to the right, or rotating in a counterclockwise direction.

[0063] In the third feasible approach, refer to Figure 6 As shown, the transmission assembly 130 may include a second transmission member 132 and a third transmission member 133 spaced apart, with the third transmission member 133 sleeved outside the second transmission member 132.

[0064] It should be noted that in this embodiment, the first transmission component 131 is omitted and a third transmission component 133 is added.

[0065] The first driving member 120 is disposed close to the second transmission member 132 and located on the side of the second transmission member 132 opposite to the mounting platform 111. The first end of the second transmission member 132 is connected to the first driving member 120, and the external teeth on the second end of the second transmission member 132 mesh with the internal teeth on the first end of the third transmission member 133. The end face of the second end of the third transmission member 133 protrudes from the surface of the mounting platform 111. The second end of the third transmission member 133 is used to place the workpiece assembly 210.

[0066] The transmission process of the transmission component 130 in this embodiment is as follows:

[0067] The drive motor drives the drive shaft 122 of the first drive member 120 to extend. The drive shaft 122 transmits the driving power to the drive shaft 135 of the second transmission member 132. The drive shaft 135 of the second transmission member 132 transmits the power to the drive shaft 135 of the third transmission member 133. The drive shaft 135 of the third transmission member 133 rotates and transmits the power and motion to the workpiece 212, thereby facilitating the positional movement of the workpiece 212.

[0068] Correspondingly, the drive motor drives the drive shaft 122 of the first drive member 120 to retract, and the drive shaft 122 transmits power to the drive shaft 135 of the second transmission member 132. The drive shaft 135 of the second transmission member 132 transmits the power to the drive shaft 135 of the third transmission member 133. The drive shaft 135 of the third transmission member 133 rotates in the opposite direction and transmits the power and motion to the workpiece 212 located on the positioning seat 211, thereby facilitating the positional movement of the workpiece 212.

[0069] It should be noted that the location, quantity, and transmission process of the transmission components 130 include, but are not limited to, the three implementation methods described above, and can be set according to the actual situation.

[0070] In some embodiments, reference is made to Figure 7 As shown, the base 110 may include a first bracket 113, a second bracket 114, a third bracket 115, and a fourth bracket 116 connected end to end in sequence. The first bracket 113 and the third bracket 115 are opposite each other, and the second bracket 114 and the fourth bracket 116 are opposite each other. The first bracket 113, the second bracket 114, the third bracket 115, and the fourth bracket 116 together form a mounting cavity 112, and the mounting platform 111 is disposed on the first bracket 113.

[0071] For example, the second bracket 114 and the fourth bracket 116 can be vertical brackets, and the first bracket 113 and the third bracket 115 can be horizontal brackets. In this way, a mounting platform 111 can be set on the horizontal first bracket 113 to place the workpiece 212. The first bracket 113 can provide support and stability for the above-mentioned structural components, so that the workpiece 212 can be placed stably.

[0072] In addition, the second support 114 and the fourth support 116 can be equipped with support legs, so that the support legs can stably support the base 110 on the ground and improve the stability of the base 110.

[0073] The first bracket 113, the second bracket 114, the third bracket 115 and the fourth bracket 116 can be connected in sequence by welding, snap-fitting or other means; or, the first bracket 113, the second bracket 114, the third bracket 115 and the fourth bracket 116 can be directly set as a single piece, which can enhance the structural strength of the base 110.

[0074] The base 110 may have a through hole 117 that connects the mounting cavity 112 and the outside. The through hole 117 passes through the mounting platform 111 and the first bracket 113, so that the transmission component 130 can pass through the through hole 117 and protrude from the surface of the mounting platform 111.

[0075] In some embodiments, the base 110 may not need to be grounded. For example, the base 110 may be replaced with a platform-like base, which is beneficial for integration and installation with other production equipment.

[0076] In summary, this application provides a transmission device 100 and a welding positioning device 200. The transmission device 100 is used to adjust the position of the positioned workpiece assembly 210. The transmission device 100 includes a first driving member 120 and a transmission component 130, and the first driving member 120 and the transmission component 130 are connected in a transmission manner. In this way, under the transmission force of the transmission component 130, the position of the positioned workpiece 212 can be adjusted to a specific direction and angle, thereby achieving the effect of cooperating with other structural components. No operator is required, which helps to reduce the labor intensity of operators during the processing, ensure the safety of operators, and improve the yield and production efficiency of water heater inner tanks.
