Description

Technical Field

[0001] This utility model relates to the technical field of electric kettle processing equipment, and in particular to a welding fixture for the spout and the kettle body. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for construction or inspection. Broadly speaking, any device used to quickly, conveniently, and safely install a workpiece at any stage of the manufacturing process can be called a fixture. Welding the spout to the body of a kettle is a crucial process in the manufacture of metal kettles (such as stainless steel teapots, coffee pots, and thermos flasks). To ensure accurate results during welding, the workpiece must be properly positioned and clamped before processing.

[0003] In existing welding fixtures for spouts and bodies, bolts or locating pins are mostly used to clamp the spout and body in order to achieve accurate positioning and minimal deviation in the processing results. However, this clamping method greatly affects efficiency, and the repeated tightening and loosening of bolts also consumes a lot of workers' energy. Utility Model Content

[0004] In order to overcome the shortcomings of traditional clamping methods that affect efficiency, this utility model provides a welding clamp for the spout and the body of the kettle.

[0005] A welding fixture for a spout and a kettle body includes a worktable, a mounting base, a kettle body, a servo motor, support members, a screw, a belt assembly, and clamping members. The mounting base is symmetrically connected to the top of the worktable, and a circular slot is formed on the top of the mounting base. The kettle body is placed in the circular slot. A servo motor is symmetrically fixedly mounted on the top of the worktable. Support members are symmetrically fixed to the left and right sides of the top of the worktable, with two corresponding support members located in front of and behind the corresponding servo motors. A screw is rotatably connected between the two corresponding support members. The threads of the screw have opposite directions at the front and rear ends, and the middle of the screw is unthreaded. The output shaft of the servo motor is connected to the middle of the screw via a belt assembly. Clamping members are symmetrically threaded onto the screw.

[0006] Optionally, it also includes a slide rail, a bidirectional motor, a second screw, a limit frame, a slider, and a limit rod. A slide rail is fixedly connected to the top center of the worktable, and the slide rail is located between two card seats. The slide rail has symmetrically opened slide grooves. A bidirectional motor is fixedly installed at the top center of the slide rail. The output shafts on both sides of the bidirectional motor are connected to the second screw. A limit frame is symmetrically fixedly connected to the top of the slide rail, and the other end of the second screw is rotatably connected to the limit frame. A slider is slidably connected in each of the two slide grooves on the slide rail. The two sliders are threadedly connected to the corresponding second screw. A limit rod is fixedly connected in each of the two slide grooves on the slide rail, and the two limit rods are slidably connected to the corresponding sliders.

[0007] Optionally, it also includes connecting blocks, molds, magnets, clamping plates, springs, and spouts. Connecting blocks are fixed to the upper part of both sliders, and molds are fixed to the other end of both connecting blocks. Each mold has a clamping groove on the side near the corresponding body of the pot. Several magnets are embedded in each clamping groove. A sliding groove is opened in the top center of each mold. Clamping plates are slidably connected inside each mold. Springs are connected between the sliding grooves and the corresponding clamping plates. The left side of the clamping plate is located above the clamping groove. Spouts are placed in the clamping grooves on both molds.

[0008] Optionally, it also includes a locator, with the locator fixed to one end of the top of the two cassettes that are far apart from each other, and the handle of the kettle body placed inside the upper part of the locator.

[0009] Optionally, the card holder, positioner, and mold are all detachable.

[0010] Optionally, the sides of the two clamping parts on the same side that contact the body of the kettle are made of rubber.

[0011] The beneficial effects of this utility model are: by using two clamping parts with rubber material to fix the position of the kettle body and a locator to fix the direction of the kettle body, the clamping speed is faster, the effect is better, and the possibility of error is greatly reduced, thus greatly improving efficiency.

The mounting base 2 is symmetrically connected to the top of the worktable 1. The top of the mounting base 2 has a circular slot, in which the kettle body 4 is placed. The servo motor 5 is symmetrically fixedly installed on the top of the worktable 1. The support component 7 is symmetrically fixed to the left and right sides of the top of the worktable 1, and the two corresponding support components 7 are located in front and behind the corresponding positions of the servo motor 5. The screw 701 is rotatably connected between the two corresponding support components 7. The threads of the front and rear parts of the screw 701 are opposite, and the middle part of the screw 701 is not threaded. The output shaft of the servo motor 5 is connected to the middle part of the screw 701 through the belt assembly 6. The clamping component 8 is symmetrically threaded to the front and rear of the screw 701. The sides of the two clamping components 8 on the same side that contact the kettle body 4 are made of rubber.

[0019] like Figure 1 and Figure 3 As shown, it also includes a slide rail 9, a bidirectional motor 10, a screw 11, a limiting frame 12, a slider 13, and a limiting rod 18. The slide rail 9 is fixedly connected to the top center of the worktable 1, and the slide rail 9 is located between two card seats 2. The slide rail 9 has symmetrically opened grooves. The bidirectional motor 10 is fixedly installed at the top center of the slide rail 9. The output shafts on both sides of the bidirectional motor 10 are connected to the screw 11. The limiting frame 12 is symmetrically fixedly connected to the top of the slide rail 9, and the other end of the screw 11 is rotatably connected to the limiting frame 12. The slider 13 is slidably connected to the two grooves on the slide rail 9. The two sliders 13 are threadedly connected to the corresponding screw 11. The limiting rod 18 is fixedly connected to the two grooves on the slide rail 9, and the two limiting rods 18 are slidably connected to the corresponding sliders 13.

[0020] like Figure 3 and Figure 4 As shown, it also includes a connecting block 1301, a mold 14, a magnet 1401, a clamping plate 16, a spring 15, and a spout 17. The upper part of each of the two sliders 13 is fixedly connected to the connecting block 1301, and the other end of each of the two connecting blocks 1301 is fixedly connected to the mold 14. Each of the two molds 14 has a clamping groove on the side near the corresponding body 4. Several magnets 1401 are embedded in each of the two clamping grooves. A sliding groove is opened in the top center of each of the two molds 14. The clamping plate 16 is slidably connected inside each of the two molds 14. A spring 15 is connected between the sliding groove and the corresponding clamping plate 16. The left part of the clamping plate 16 is located above the clamping groove. The spout 17 is placed in the clamping groove on each of the two molds 14. The card seat 2, the positioner 3, and the mold 14 are all detachable.

[0021] like Figure 1 and Figure 2As shown, it also includes a locator 3. The locator 3 is fixed to one end of the top of the two card holders 2 that is far apart from each other, and the handle of the pot body 4 is placed inside the upper part of the locator 3.

[0022] When the worker needs to clamp the spout 17 to the body 4 for the next welding step, first place the body 4 into the slot on the holder 2 and place the handle of the body 4 in the upper part of the positioner 3. Then, start the servo motor 5. The output shaft of the servo motor 5 drives the belt assembly 6 and the screw 701 to rotate. During the rotation of the screw 701, the two clamping parts 8 move towards each other. When the rubber side of the clamping part 8 contacts the body 4, the body 4 is clamped and fixed. Then, the clamping plate 16 is pulled upward. At this time, the spring 15 is in a stretched state. Then, the spout 17 is placed into the clamping groove on the mold 14. When the spout 17 is placed into the clamping groove, it will be attracted by the magnet 1401. Then the clamping plate 16 is released, the spring 15 is gradually compressed and drives the clamping plate 16 to move down. Then the left side of the clamping plate 16 contacts the spout 17. At this time, the spring 15 is still in the stretched state, and the spout 17 is clamped in the clamping groove on the mold 14. Then the worker can start the bidirectional motor 10. The output shaft of the bidirectional motor 10 drives the two screws 11 to rotate, and the two sliders 13 move towards the opposite end. When they move to the required position, the bidirectional motor 10 is turned off. Finally, the worker can manually carry out the next welding process. At this time, the clamping of the spout 17 and the body 4 is completed.

[0023] After the worker finishes welding the body and spout of the kettle, the clamp 16 is pulled upwards. At this time, the spring 15 is in a stretched state. Then the bidirectional motor is started. The output shaft of the bidirectional motor 10 rotates in the opposite direction, driving the two screws 11 to rotate. The two sliders 13 move towards the end that is close to each other. When they move to the desired position and the magnet leaves the range of magnetic force generated by the spout, the bidirectional motor 10 is turned off. Then the clamp 16 is released. The spring 15 is gradually compressed and drives the clamp 16 to return to its original position. Finally, the welded spout 17 and kettle body 4 can be removed from the holder 2.
