Description

Technical Field

[0001] This utility model relates to the field of spot welding fixture technology, specifically a spot welding fixture for manufacturing parts for industrial robots. Background Technology

[0002] Spot welding is a resistance welding process in which pressure and current are applied to a metal workpiece through electrodes, and the heat generated by the contact resistance is used to locally melt the metal to form a weld point. Spot welding fixtures are used to fix and limit the objects to be welded during spot welding.

[0003] Spot welding is relatively fast, which means that the device needs to be clamped constantly during use. A significant portion of the spot welding process is spent clamping the parts, which makes the spot welding inefficient. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model proposes a spot welding fixture for manufacturing parts for industrial robots, which can improve the efficiency of spot welding. Moreover, the device has a simple structure and is not easily damaged during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spot welding fixture for manufacturing parts for industrial robots, comprising a support frame, a rotating ring rotatably connected to the upper surface of the support frame, and multiple part placement slots formed on the upper surface of the rotating ring, a clamping assembly provided on one side of each part placement slot, a strip groove formed on the upper surface of the support frame, a limiting top member provided on one side of the strip groove, a material leakage hole formed on the upper surface of the support frame, and a driving mechanism provided on one side of the support frame.

[0006] Preferably, the clamping assembly includes a push rod disposed in the part placement slot, with one end of the push rod passing through the rotating ring and extending to the outside of the rotating ring. A spring is sleeved on the outer wall of the push rod located outside the rotating ring, and one end of the spring is fixedly connected to the push rod.

[0007] Preferably, the limiting top member includes an inclined top plate disposed above the strip groove, and a threaded rod is disposed below the inclined top plate. One end of the threaded rod passes through the strip groove and extends to the other side of the strip groove. A nut is threadedly connected to the outer wall of the threaded rod located on the other side of the strip groove.

[0008] Preferably, the drive mechanism includes a motor fixedly connected to the support frame, and the drive end of the motor passes through the support frame and is fixed to the rotating ring.

[0009] Preferably, a flexible sheet is fixedly connected to one end of the top rod.

[0010] Preferably, one end of the top rod has a groove, and a ball bearing is provided in the groove.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention, through the coordinated use of a drive mechanism, a clamping assembly, and a limiting top member, allows the drive mechanism to rotate a rotating ring during spot welding. After the ring rotates to a certain angle, the limiting top member actuates the clamping assembly, fixing the part for subsequent welding. During welding, other parts can be placed into the slot for loading, saving loading time. After welding, the drive mechanism can rotate the ring, and the welded part automatically falls down after rotating above the discharge hole. This ensures that loading and unloading parts does not take too long, thereby improving the efficiency of the device. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1-4 A spot welding fixture for manufacturing parts for industrial robots includes a support frame 1, a rotating ring 2 rotatably connected to the upper surface of the support frame 1, and multiple part placement slots 3 formed on the upper surface of the rotating ring 2. A clamping assembly is provided on one side of the part placement slots 3. A strip groove 4 is formed on the upper surface of the support frame 1, and a limiting top member is provided on one side of the strip groove 4. A material leakage hole 5 is formed on the upper surface of the support frame 1, and a driving mechanism is provided on one side of the support frame 1.

[0020] As can be seen from the above structure, by setting the drive mechanism, clamping assembly and limiting top part to work together, the drive mechanism can drive the rotating ring 2 to rotate during spot welding. After the rotating ring 2 rotates to a certain angle, the limiting top part can push the clamping assembly to fix the part for subsequent welding. During welding, other parts can be placed in the slot 3 to save loading time. After welding is completed, the drive mechanism can drive the rotating ring 2 to rotate. After the welded part rotates to the top of the discharge hole 5, the part can automatically fall down. This makes loading the part less time-consuming, thereby improving the efficiency of the device.

[0021] Furthermore, the clamping assembly includes a push rod 6 disposed in the part placement groove 3, and one end of the push rod 6 passes through the rotating ring 2 and extends to the outside of the rotating ring 2. A spring 7 is sleeved on the outer wall of the push rod 6 located outside the rotating ring 2, and one end of the spring 7 is fixedly connected to the push rod 6. By setting the push rod 6, when one end of the push rod 6 abuts against the limiting push member, one end of the push rod 6 can abut against the part in the part placement groove 3, thereby fixing the part before welding.

[0022] Furthermore, the limiting top component includes an inclined top plate 13 disposed above the strip groove 4, and a threaded rod 8 disposed below the inclined top plate 13. One end of the threaded rod 8 passes through the strip groove 4 and extends to the other side of the strip groove 4. A nut 9 is threadedly connected to the outer wall of the threaded rod 8 located on the other side of the strip groove 4. By providing the inclined top plate 13, when one end of the top rod 6 abuts against the inclined top plate 13, one end of the top rod 6 can abut against the part placed in the part placement groove 3. By providing the nut 9 to cooperate with the threaded rod 8, the inclined top plate 13 can be fixed. The position of the inclined top plate 13 can be adjusted, so that the position of the inclined top plate 13 can be adjusted according to the size of the part to be fixed, so that the inclined top plate 13 can push the top rod 6 further or closer, so that the top rod 6 can fix large parts or small parts, thereby improving the practicality of the device.

[0023] Furthermore, the drive mechanism includes a motor 10 fixedly connected to the frame 1, and the drive end of the motor 10 passes through the frame 1 and is fixed to the rotating ring 2; by setting the motor 10, the rotating ring 2 can be driven.

[0024] Furthermore, a flexible plate 11 is fixedly connected to one end of the push rod 6; by setting the flexible plate 11, it can act as a soft pad between the part and the push rod 6, so as to prevent the push rod 6 from damaging the product.

[0025] Furthermore, a groove is provided at one end of the push rod 6, and a ball bearing 12 is provided in the groove; by providing the ball bearing 12, the friction between the push rod 6 and the inclined top plate 13 can be reduced.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
