Description

Technical Field

[0001] This utility model relates to the field of pneumatic clamping technology for stainless steel housings, and in particular to an adjustable pneumatic clamping welding fixture for stainless steel housings. Background Technology

[0002] Stainless steel casings are widely used in industrial production, encompassing electronic equipment, machinery, and architectural decoration, among many other fields. Welding, a crucial process in the processing of stainless steel casings, directly impacts product performance and lifespan. Securely clamping the stainless steel casing during welding is a vital prerequisite for ensuring weld quality.

[0003] Traditional welding clamping fixtures have several drawbacks. Firstly, their adjustment range is limited, typically only suitable for clamping stainless steel shells of specific sizes. When faced with stainless steel shells of different sizes, they often fail to meet requirements, necessitating frequent fixture changes, which increases production costs and reduces efficiency. Secondly, due to inflexible adjustment, they may not achieve precise positioning and secure clamping of the stainless steel shell during the clamping process, easily leading to shell displacement during welding. This affects welding accuracy and quality, resulting in welding defects such as uneven welds and insufficient weld strength. Therefore, we propose an adjustable pneumatic clamping welding fixture for stainless steel shells to address these issues. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adjustable stainless steel shell pneumatic clamping welding fixture.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable stainless steel housing pneumatic clamping welding fixture includes a base plate. Connecting platforms are fixed to both sides of the upper end of the base plate. A sliding groove is provided on one side of each connecting platform, and a reciprocating moving mechanism is installed within the sliding groove. A cylinder and a folding frame are installed at one end of each reciprocating moving mechanism and connecting platform on the same side. A second clamping plate is connected to one end of each cylinder and folding frame. Two second clamping plates on the same side are connected by a guide mechanism. A traveling mechanism is installed at the lower end of each second clamping plate, and a first clamping plate is inserted into the upper end of each second clamping plate. A support platform is installed in the middle of the upper end of the base plate.

[0007] Preferably, the reciprocating moving mechanism includes a stud rotatably connected between opposite sidewalls within the slide groove, a servo motor is mounted on one side of the connecting platform, the output shaft of the servo motor is connected to one end of the stud, a slider is mounted within the slide groove, and the stud is threaded onto the slider.

[0008] Preferably, one end of the slider and the connecting platform is fixed with a movable block, one end of the two folding frames on the same side is rotatably connected to one side of the two movable blocks, the other end of the folding frame is rotatably connected to one side of the second clamping plate, one end of the two cylinders on the same side is fixed to one side of the two movable blocks, and the end of the piston rod of the cylinder is fixed to one side of the second clamping plate.

[0009] Preferably, the guiding mechanism includes a guide rod fixed to one end of one of the second clamping plates on the same side, the guide rod passing through the other second clamping plate on the same side and extending to one side thereto.

[0010] Preferably, the walking mechanism includes a fixing member connected to the lower end of the second clamping plate via a rotating shaft, and two rollers are rotatably connected to the fixing member.

[0014] 2. Adjusting the clamping range: Start the servo motor, and its output shaft drives the stud to rotate. Since the stud is threaded onto the slider, the slider will move linearly along the stud in the groove. The slider and the moving block at one end of the connecting table move accordingly, thereby driving the folding frame and the cylinder to move, so that a second clamping plate on one side moves. The traveling mechanism at the lower end of the second clamping plate consists of a fixed part, rollers and a rotating shaft. It has a universal wheel structure and can move stably under the limit of the guide rod, thereby expanding the clamping range to adapt to stainless steel shells of different sizes.

[0015] 3. Clamping the housing: After the clamping range is adjusted, the piston rods of the two cylinders on the same side extend or retract under the drive of the synchronous control system, pushing the second clamping plate to move towards the middle until the stainless steel housing is firmly clamped. The clamping plate is equipped with a pressure sensor to provide real-time feedback on the clamping strength and avoid over-clamping.

[0016] 4. Selective assembly of the first clamping plate: Based on the height of the stainless steel shell, insert the pins on both sides of the lower end of the first clamping plate into the pin holes at the upper end of the second clamping plate to achieve selective assembly of the first clamping plate and further enhance the clamping effect on the stainless steel shell.

[0017] 5. Perform welding operation: After the stainless steel shell is firmly clamped, welding can be carried out. After welding is completed, the cylinder retracts, the clamp on the shell is released, and the welded shell is taken out.

[0018] This utility model has the following advantages:

[0019] 1. Through the coordinated action of the reciprocating moving mechanism and the cylinder, the clamping range can be flexibly adjusted according to the stainless steel shells of different sizes, realizing the clamping of shells of various specifications, which greatly improves the versatility and adaptability of the tooling and reduces the time and cost waste caused by changing the tooling.

[0020] 2. The traveling mechanism at the lower end of the second clamping plate adopts a universal wheel structure and moves under the limit of the guide rod, which ensures the stability of the second clamping plate during movement, enables precise positioning and firm clamping of the stainless steel shell, effectively avoids displacement of the shell during welding, and improves welding quality.

[0021] 3. The selective assembly of the first clamping plate allows the tooling to be adjusted according to the height of the stainless steel shell, further enhancing its adaptability to shells of different specifications and ensuring good clamping effect under various conditions.

[0022] In summary, this utility model can flexibly adjust the clamping range according to stainless steel shells of different sizes, realizing the clamping of shells of various specifications, greatly improving the versatility and adaptability of the tooling. Its wide adjustment range and flexible operation can quickly adapt to different production needs, reduce the time for tooling adjustment and replacement, thereby improving production efficiency and reducing production costs.

Detailed Implementation

[0031] 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.

[0032] Reference Figure 1-7 An adjustable stainless steel shell pneumatic clamping welding fixture includes a base plate 10. Both sides of the upper end of the base plate 10 are fixed with connecting platforms 11. One side of the connecting platform 11 is provided with a slide groove 16. A reciprocating moving mechanism is installed in the slide groove 16. On the same side, a cylinder 6 and a folding frame 5 are installed on one end of the reciprocating moving mechanism and one end of the connecting platform 11. One end of the cylinder 6 and the folding frame 5 are connected to a second clamping plate 4. The coordinated action of the reciprocating moving mechanism and the cylinder can flexibly adjust the clamping range according to the stainless steel shells of different sizes, so as to achieve clamping of shells of various specifications.

[0033] The two second clamping plates 4 on the same side are connected by a guide mechanism. A walking mechanism is installed at the lower end of the second clamping plate 4, and a first clamping plate 3 is inserted into the upper end of the second clamping plate 4. A support platform 8 is installed in the middle of the upper end of the base plate 10. The selective assembly of the first clamping plate allows the tooling to be adjusted according to the height of the stainless steel shell, further enhancing the adaptability to shells of different specifications and ensuring good clamping effect under various conditions.

[0034] The reciprocating movement mechanism includes a stud 18 rotatably connected between opposite side walls within the slide groove 16. A servo motor 1 is mounted on one side of the connecting platform 11. The output shaft of the servo motor 1 is connected to one end of the stud 18. A slider 15 is installed within the slide groove 16. The stud 18 is threaded onto the slider 15. When the servo motor 1 starts, the output shaft drives the stud 18 to rotate. Due to the threaded engagement, the slider 15 will move linearly along the stud 18 within the slide groove 16. The movement of the moving block 17 will drive the folding frame 5 and the cylinder 6 to move, thereby achieving the position adjustment of the second clamping plate 4.

[0035] One end of the slider 15 and the connecting platform 11 is fixed with a moving block 17. One end of the two folding frames 5 on the same side is rotatably connected to one side of the two moving blocks 17, and the other end of the folding frame 5 is rotatably connected to one side of the second clamping plate 4. One end of the two cylinders 6 on the same side is fixed to one side of the two moving blocks 17, and the piston rod end of the cylinder 6 is fixed to one side of the second clamping plate 4. Pressure sensors are installed on one side of the first clamping plate 3 and the second clamping plate 4. During the clamping process, the operator can adjust the action of the cylinder 6 in time according to the feedback information of the pressure sensor to avoid over-clamping and damage to the housing. At the same time, the use of pressure sensors can also ensure that the clamping force is uniform each time and improve the stability of welding quality.

[0036] The guiding mechanism includes a guide rod 2 fixed to one end of one of the second clamping plates 4 on the same side. The guide rod 2 passes through the other second clamping plate 4 on the same side and extends to one side of it. The function of the guide rod 2 is to ensure the stability and synchronization of the two second clamping plates 4 on the same side during the movement, prevent the second clamping plates 4 from shifting during the movement, and ensure the accuracy of the clamping operation.

[0037] The walking mechanism includes a fixing member 9 connected to the lower end of the second clamping plate 4 via a rotating shaft 13. Two rollers 7 are rotatably connected to the fixing member 9. This structure forms a structure similar to a universal wheel, making the second clamping plate 4 more flexible during movement. At the same time, under the limiting action of the guide rod 2, the walking mechanism can ensure the stable movement of the second clamping plate 4 and avoid swaying or tilting.

[0038] The upper end of the second clamping plate 4 is provided with two insertion holes 12, and the lower ends of the first clamping plate 3 are fixed with insertion rods 14 on both sides. The two insertion rods 14 on the same side are inserted into the two insertion holes 12 on the same side. The first clamping plate 3 can be selectively assembled according to the height of the stainless steel shell, thereby further enhancing the clamping effect on the stainless steel shell and improving the applicability of the tooling.

[0039] In this utility model, during welding:

[0040] 1. Place the shell to be welded: Place the stainless steel shell to be welded on the support platform 8 at the middle of the upper end of the base plate 10 to prepare for subsequent clamping and welding operations.

[0041] 2. Adjusting the clamping range: Start the servo motor 1, and its output shaft drives the stud 18 to rotate. Since the stud 18 is threaded onto the slider 15, the slider 15 will move linearly along the stud 18 in the slide groove 16. The slider 15 and the moving block 17 at one end of the connecting platform 11 move accordingly, thereby driving the folding frame 5 and the cylinder 6 to move, so that the corresponding second clamping plate 4 on one side moves. The traveling mechanism at the lower end of the second clamping plate 4 is composed of a fixing part 9, a roller 7 and a rotating shaft 13. It has a universal wheel structure and can move stably under the limit of the guide rod 2, thereby expanding the clamping range to adapt to stainless steel shells of different sizes.

[0042] 3. Clamping the housing: After the clamping range is adjusted, the piston rods of the two cylinders 6 on the same side extend or retract under the drive of the synchronous control system, pushing the second clamping plate 4 to move towards the middle until the stainless steel housing is firmly clamped. The clamping plate 4 is equipped with a pressure sensor to provide real-time feedback on the clamping strength and avoid over-clamping.

[0043] 4. Selective assembly of the first clamping plate: Based on the height of the stainless steel shell, insert the rods 14 on both sides of the lower end of the first clamping plate 3 into the insertion holes 12 at the upper end of the second clamping plate 4 to achieve selective assembly of the first clamping plate 3 and further enhance the clamping effect on the stainless steel shell.

[0044] 5. Perform welding operation: After the stainless steel shell is firmly clamped, welding can be performed. After welding is completed, cylinder 6 retracts, releasing the clamp on the shell and removing the welded shell.

[0045] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
