Description

Technical Field

[0001] This utility model relates to the field of automotive interior panel welding, and in particular to an easy-to-fix interior panel welding fixture. Background Technology

[0002] The tailgate of a car usually refers to the trunk opening door of a hatchback or SUV. Most of them adopt an upward-opening structure and are the most important opening parts of the car body. They play a very important role in vehicle opening, luggage storage, decoration, and parts repair. The quality of the tailgate is mainly reflected in its impact resistance, sealing performance, ease of opening and closing, and other performance indicators. The inner panel of the tailgate needs to be clamped and fixed by welding fixtures during the processing and welding process.

[0003] In the process of developing this application, the inventors discovered the following problems with the prior art:

[0004] In the existing technology, since the clamping direction of the welding fixture is relatively fixed, when the inner plate needs to be erected for welding, it is usually necessary to replace the vertical fixture, which is quite laborious. In addition, the two clamping mechanisms in the existing fixture are fixed to the base plate, which makes it inconvenient to adjust the height of the two clamping mechanisms according to the height of different workers.

[0005] Therefore, those skilled in the art have provided an inner plate welding fixture that is easy to fix, in order to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an easy-to-fix inner plate welding fixture. The clamping direction of the welding fixture can be adjusted to facilitate the internal welding by standing it upright. At the same time, the height of the clamping mechanism can be adjusted to accommodate the height of different workers.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A convenient fixing inner plate welding fixture includes a base, a first bidirectional screw rotatably disposed at the center of both sides of the inner wall of the base, two fixing columns slidably disposed inside the base, a fixing shell fixedly disposed at the center of one side of the upper end face of each of the two fixing columns, a fixing mechanism disposed inside each of the two fixing shells, each of the two fixing mechanisms including a pull plate, a pull rod fixedly disposed at the center of the lower end face of each of the two pull plates, a second spring movably sleeved on the outer wall of each of the two pull rods, an insert fixedly disposed at the lower end of each of the two pull rods, and a rotating shaft rotatably disposed at the upper center of the opposite side of each of the two fixing columns;

[0009] A connecting rod is fixedly installed at the center of each of the two rotating shafts on opposite sides. A housing is rotatably installed at the lower end of each of the two connecting rods on opposite sides. A locking mechanism is installed at the center of each of the two housings on opposite sides. Each locking mechanism includes a telescopic rod and multiple locking rods. A first spring is movably sleeved on the outer wall of each of the two telescopic rods. A rotating block is fixedly installed at one end of each of the two telescopic rods. A clamping mechanism is installed inside each of the two housings. Each clamping mechanism includes a second bidirectional screw. Clamping blocks are threadedly sleeved at the upper and lower ends of the outer wall of each second bidirectional screw.

[0010] Furthermore, the two bidirectional screws are respectively rotatably disposed at the center of the lower end face of the inner wall of the two outer shells, and the four clamping blocks are respectively slidably disposed in pairs inside one of the two outer shells.

[0011] Furthermore, the two telescopic rods are respectively fixedly installed at the center of the outer walls of the two outer shells on opposite sides, and the multiple locking rods are respectively fixedly installed at the center of the outer walls of the two outer shells on opposite sides, located outside the two telescopic rods. The two No. 1 springs are respectively fixedly connected to the two rotating blocks and the two outer shells at both ends.

[0012] Furthermore, each of the two connecting rods has a receiving groove at the center of its lower end on the opposite side, and multiple locking grooves are provided at the center of its lower end on the opposite side of the two receiving grooves on the outside of the two receiving grooves. Multiple locking rods are respectively embedded in the multiple locking grooves, and the two rotating blocks are respectively rotatably disposed on one side of the inner wall of the two receiving grooves.

[0013] Furthermore, the two ends of the two second springs are respectively fixedly connected to the upper ends of the two inserts and the upper end faces of the inner walls of the two fixed shells.

[0014] Furthermore, multiple slots are provided at the center of the outer walls of the two shafts, and the two inserts are respectively embedded in one of the multiple slots provided in the outer walls of the two shafts.

[0015] Furthermore, the two ends of the first bidirectional screw are threaded through the lower center of the opposite side of the two fixed posts, and a motor is fixedly installed at the center of one side of the outer wall of the base. The output end of the motor is fixedly connected to one end of the first bidirectional screw.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model proposes an easy-to-fix inner plate welding clamp. Pulling the pull plate upward causes the pull rod to move upward, thereby allowing the insert to disengage from the groove. At this time, the connecting rod can be rotated by rotating the shaft. When the connecting rod rotates to the appropriate position, the pull plate is released, allowing the insert to be embedded into the groove under the action of the second spring. The rotation angle of the shaft is fixed, thereby adjusting the vertical height of the clamping mechanism and the ground. This allows the device to adapt to the working height of operators of different heights.

[0018] 2. The present invention proposes an easy-to-fix inner panel welding clamp. Pulling the outer shell to one side extends the telescopic rod and drives the No. 1 spring to stretch. After pulling the outer shell until multiple locking rods disengage from multiple locking slots, the outer shell is rotated by a rotating block. After rotating to a suitable position, the outer shell is released, causing the telescopic rod to retract under the elastic force of the No. 1 spring and drive multiple locking rods to embed into multiple locking slots to fix the rotation angle of the outer shell. This can achieve the effect of adjusting the clamping direction of the clamping mechanism, so that the clamping mechanism can clamp the inner panel of the car laterally and longitudinally.

[0026] 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.

[0027] Reference Figure 1 ,to Figure 4 One embodiment provided by this utility model:

[0028] A welding fixture for easy fixing of inner plates includes a base 1. A first bidirectional screw 14 is rotatably arranged at the center of both sides of the inner wall of the base 1. Two fixing posts 2 are slidably arranged inside the base 1. A fixing shell 7 is fixedly arranged at the center of one side of the upper end face of each of the two fixing posts 2. A fixing mechanism 12 is arranged inside each of the two fixing shells 7. Each fixing mechanism 12 includes a pull plate 1201. A pull rod 1202 is fixedly arranged at the center of the lower end face of each of the two pull plates 1201. A second spring 1203 is movably sleeved on the outer wall of each of the two pull rods 1202. An insert 1204 is fixedly arranged at the lower end of each of the two pull rods 1202. A rotating shaft 6 is rotatably arranged at the upper end of the center of the opposite side of each of the two fixing posts 2.

[0029] Two rotating shafts 6 are each fixedly provided with a connecting rod 3 at the center of their opposite sides. The lower ends of the two connecting rods 3 are each rotatably provided with a housing 4. The center of the two housings 4 on opposite sides is provided with a locking mechanism 9. The two locking mechanisms 9 each include a telescopic rod 903 and multiple locking rods 904. The outer walls of the two telescopic rods 903 are movably sleeved with a first spring 902. One end of the two telescopic rods 903 is fixedly provided with a rotating block 901. The inside of the two housings 4 is provided with a clamping mechanism 5. The two clamping mechanisms 5 each include a second bidirectional screw 502. The upper and lower ends of the outer walls of the two second bidirectional screws 502 are threadedly sleeved with clamping blocks 501.

[0030] Specifically, the distance between the two fixing posts 2 can be adjusted by the first bidirectional screw 14 inside the base 1, thereby achieving the effect of adjusting the distance between the fixing posts 2 to adapt to different specifications of the rear door inner panel. At the same time, the rotation angle of the connecting rod 3 can be adjusted and fixed by the fixing mechanism 12 in conjunction with the rotating shaft 6. The inner panel can be clamped and fixed by the outer shell 4 and the clamping mechanism 5, and the rotation angle of the outer shell 4 can be fixed and adjusted by the locking mechanism 9, thereby facilitating the adjustment and fixing of the clamping angle of the back panel.

[0031] Reference Figure 1 , Figure 2 , Figure 5Two bidirectional screws 502 are respectively rotatably set at the center of the lower end face of the inner wall of the two outer shells 4, and four clamping blocks 501 are respectively slidably set in pairs inside one of the two outer shells 4.

[0032] Specifically, rotating the second bidirectional screw 502 causes the two clamping blocks 501 located inside the same outer shell 4 to move in opposite directions, thereby achieving the clamping effect on the inner panel of the car.

[0033] Reference Figure 1 , Figure 2 Two telescopic rods 903 are fixedly installed at the center of the outer wall of the two outer shells 4 on opposite sides. Multiple locking rods 904 are fixedly installed at the center of the outer wall of the two outer shells 4 on opposite sides, located outside the two telescopic rods 903. The two No. 1 springs 902 are fixedly connected at both ends to the two rotating blocks 901 and the two outer shells 4 respectively.

[0034] Specifically, pulling the outer shell 4 stretches the telescopic rod 903 and the first spring 902. When the multiple locking rods 904 disengage from the multiple locking slots 11, rotating the outer shell 4 adjusts the clamping direction of the clamping mechanism 5. At this time, releasing the outer shell 4 causes the telescopic rod 903 to retract under the action of the first spring 902 and drives the multiple locking rods 904 to embed into the multiple locking slots 11, thus fixing the rotation angle of the outer shell 4.

[0035] Reference Figure 2 Each of the two connecting rods 3 has a receiving groove 10 at the center of the lower end on the opposite side. Each of the two connecting rods 3 has a plurality of locking grooves 11 at the center of the lower end on the opposite side, located outside the two receiving grooves 10. A plurality of locking rods 904 are respectively embedded in the plurality of locking grooves 11. Two rotating blocks 901 are respectively rotatably set on one side of the inner wall of the two receiving grooves 10.

[0036] Specifically, by embedding the locking rod 904 into the locking groove 11, the rotation angle of the outer casing 4 can be fixed.

[0037] Reference Figure 3 The two ends of the two No. 2 springs 1203 are fixedly connected to the upper ends of the two inserts 1204 and the upper end faces of the inner walls of the two fixed shells 7, respectively.

[0038] Specifically, pulling the insert 1204 causes the second spring 1203 to contract, so that when the insert 1204 is released, it can move downward under the action of the second spring 1203.

[0039] Reference Figure 3 , Figure 4 Multiple slots 13 are provided at the center of the outer wall of each of the two rotating shafts 6, and the two inserts 1204 are respectively embedded in one of the multiple slots 13 provided in the outer wall of the two rotating shafts 6.

[0040] Specifically, by embedding the insert 1204 into the groove 13, the rotation angle of the rotating shaft 6 can be fixed, thereby achieving the same effect as fixing the rotation angle of the connecting rod 3.

[0041] Reference Figure 1 The two ends of the No. 1 bidirectional screw 14 are threaded through the center of the lower end of the two fixed posts 2 on opposite sides. A motor 8 is fixedly installed at the center of one side of the outer wall of the base 1. The output end of the motor 8 is fixedly connected to one end of the No. 1 bidirectional screw 14.

[0042] Specifically, the motor 8 drives the first bidirectional screw 14 to rotate, thereby adjusting the distance between the two fixed posts 2.

[0043] Working principle: Pulling the pull plate 1201 upwards causes the pull rod 1202 and the insert 1204 to move upwards and compress the second spring 1203. At the same time, the insert 1204 disengages from the slot 13. At this time, the connecting rod 3 can be rotated through the rotating shaft 6, which can drive the outer shell 4 to rotate, thereby adjusting the vertical distance between the clamping mechanism 5 and the ground, so as to accommodate the use of workers of different heights. Pulling the outer shell 4 to one side stretches the telescopic rod 903 and the first spring 902. At this time, multiple locking rods 904 disengage from multiple locking slots 11, thus achieving the rotation effect of the outer shell 4, thereby changing the rotation angle of the inner plate, which is convenient for welding different positions of the inner plate.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
