Description

Technical Field

[0001] This application relates to the field of welding auxiliary fixture technology, and more specifically, to a welding auxiliary fixture for automotive air conditioning control panel screens. Background Technology

[0002] In the automotive manufacturing industry, the welding of automotive air conditioning control panel screens is a critical and delicate process. With the increasing intelligence and integration of automotive interiors, the size, shape, and functional complexity of air conditioning control panel screens are growing, placing higher demands on welding quality and precision.

[0003] Traditional welding methods have revealed many problems in the welding process of automotive air conditioning control panel screens. Some existing welding fixtures have relatively simple functions and cannot adapt to different models and sizes of automotive air conditioning control panel screens. For example, the clamping structure of some fixtures is fixed and cannot be flexibly adjusted according to the screen model. When facing diverse product requirements, they lack sufficient versatility and adaptability.

[0004] To address the aforementioned issues, this application provides an auxiliary fixture for welding automotive air conditioning control panel screens. Utility Model Content

[0005] The technical solution of the auxiliary fixture for welding automotive air conditioning control panel screens provided in this application is as follows: A welding auxiliary fixture for an automotive air conditioning control panel screen includes a base, an auxiliary mechanism on the outer side of the base, and the auxiliary mechanism extending into the interior of the base. The auxiliary mechanism includes two movable frames, both located on top of the base. Each movable frame has a rotating rod embedded inside. The inner ends of each rotating rod have square slots, and square blocks are embedded within each square slot. Grippers are fixedly connected to the inner ends of each square block. Annular slots are formed on the inner sides of each movable frame, and limiting blocks are embedded within each annular slot. Connecting blocks are fixedly connected to the inner sides of each limiting block. Screws are threaded into the inner sides of each connecting block. Pins are fitted onto the outer sides of the bottom ends of each screw. The bottom ends of each pin extend into the interior of the two square blocks, and connecting components are provided on the outer sides of each pin.

[0006] Furthermore, the connecting component includes two knobs, which are respectively fixedly connected to the top of the screw.

[0007] The above technical solution, by setting two knobs, facilitates the rotation of the two screws later.

[0008] Furthermore, the two rotating rods are movably connected to the two movable frames via bearings, and the two screws are movably connected to the two pins via bearings.

[0009] Furthermore, both grippers are fixedly connected to anti-slip memory pads at their bottom and bottom, and a motor is fixedly connected to one side of the movable frame, with the motor output shaft fixedly connected to a rotating rod on one side.

[0010] The above technical solution, by setting four anti-slip memory pads, makes it easier to fix the screen in place later, while also reducing damage to the screen.

[0011] Furthermore, a base plate is fixedly connected to the bottom of the motor, and the base plate is fixedly connected to a movable frame on one side.

[0012] The above technical solution, by setting a base plate, can support the motor, thereby making the motor run more stably.

[0013] Furthermore, the base has two grooves inside, which are symmetrically arranged about the center line of the base.

[0014] By using the above technical solution, two grooves can be set to limit the slider, thereby making the movement of the two moving frames more stable.

[0015] Furthermore, an electric push rod is fixedly embedded inside each of the two grooves, and a slider is fixedly connected to the inner end of each of the two electric push rods. The two sliders are respectively fixedly connected to the bottom of the two movable frames.

[0016] The above technical solution allows two sliders to move towards each other or in opposite directions by setting two electric push rods.

[0017] In summary, this application includes the following beneficial technical effects: In use, the two screws can be rotated through the connecting parts. Since the cross-section of the two pins is square, the two pins will move vertically upward when the two screws are rotated. After the two pins are disengaged from the two square blocks, the two grippers can be disassembled and replaced. The replaceable design of the grippers and the two movable frames not only greatly improves the versatility of the auxiliary fixture and can adapt to the welding needs of various shapes of automotive air conditioning control panel screens, but also reduces the cost for enterprises to frequently change fixtures due to the diversification of product models.

[0023] Example: This application discloses an auxiliary fixture for welding automotive air conditioning control panel screens. Please refer to [link / reference]. Figure 1 and Figure 3 It includes a base 1, an auxiliary mechanism on the outside of the base 1, and the auxiliary mechanism extends into the base 1; The auxiliary mechanism includes two movable frames 2, both of which are located on top of the base 1. A rotating rod 3 is embedded inside each of the two movable frames 2. A square groove is opened at the inner end of each of the two rotating rods 3. A square block 4 is embedded inside each of the two square grooves. A gripper 5 is fixedly connected to the inner end of each of the two square blocks 4. An annular groove is opened on the inner side of each of the two movable frames 2. A limiting block 6 is embedded inside each of the two annular grooves. A connecting block 7 is fixedly connected to the inner side of each of the two limiting blocks 6. A screw rod 8 is threaded into each of the two connecting blocks 7. A pin 9 is sleeved on the outer side of the bottom end of each of the two screw rods 8. The bottom ends of the two pins 9 extend into the interior of the two square blocks 4 respectively. Please see Figure 2 The two pins 9 are provided with connecting parts on their outer sides. The connecting parts include two knobs 10. The two knobs 10 are fixedly connected to the top of the screw 8. The two rotating rods 3 are connected to the two movable frames 2 through bearings. The two screws 8 are connected to the two pins 9 through bearings. Please see Figure 1 and Figure 3 The bottom of each of the two grippers 5 is fixedly connected to an anti-slip memory pad 11. A motor 12 is fixedly connected to one side of the movable frame 2. The output shaft of the motor 12 is fixedly connected to a rotating rod 3 on one side. A base plate 13 is fixedly connected to the bottom of the motor 12. The base plate 13 is fixedly connected to the movable frame 2 on one side. Please see Figure 1 The base 1 has two grooves inside, which are symmetrical about the center line of the base 1. An electric push rod 14 is fixedly embedded in each of the two grooves. A slider 15 is fixedly connected to the inner end of each of the two electric push rods 14. The two sliders 15 are fixedly connected to the bottom of the two movable frames 2 respectively.

[0024] The implementation principle of this embodiment is as follows: During the processing of the car air conditioning control panel screen, when the operator needs to weld the screen of the air conditioning control panel, he must first hold the car air conditioning control panel screen and place it inside the side gripper 5. Then, he simultaneously starts the two electric push rods 14, so that the telescopic ends of the two electric push rods 14 drive the two moving frames 2 to move towards each other through the two sliders 15. When the two anti-slip memory pads 11 inside the two grippers 5 are tightly pressed against the car air conditioning control panel screen, the power of the two electric push rods 14 can be turned off, and the welding tool can be operated to weld the screen. During this period, the motor 12 can also be started, and the output shaft of the motor 12 drives the rotating rod 3 on one side to rotate. The rotating rod 3 on one side can flexibly adjust the angle of the screen by cooperating with the two square blocks 4 and the rotating rod 3 on the other side, thereby improving the welding accuracy and work efficiency. Since the two limit blocks 6 are matched with the two annular grooves respectively, the two grippers 5 can be more stable and firm when rotating. Later, by rotating the two knobs 10 in sequence, the two screws 8 will rotate accordingly. Since the cross-section of the two pins 9 is square, when the two screws 8 rotate, the two pins 9 will move vertically upward. After the two pins 9 are disengaged from the two square blocks 4, the two grippers 5 can be disassembled and replaced. The replaceable design of the grippers 5 and the two movable frames 2 not only greatly improves the versatility of the auxiliary fixture and can adapt to the welding needs of various shapes of automotive air conditioning control panel screens, but also reduces the cost for enterprises to frequently change fixtures due to the diversification of product models.

[0025] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
