Fixing clamp with turnover structure for welding seat framework

Abstract

The utility model discloses a seat framework welding fixing clamp with an overturning structure, which comprises a movable clamp seat A. One side of the movable clamp seat A is provided with a movable clamp seat B used for transversely adjusting the width of a clamping distance. Lifting vertical plates for adjusting the height of overturning seat frameworks with different lengths are arranged on one side of the end of the movable clamp base A and one side of the end of the movable clamp base B. When the seat frameworks need to be overturned after being clamped and fixed through the center fixing clamp, the height of the lifting vertical plates is adjusted through lifting of an air cylinder B according to the difference of the longitudinal width of the seat frameworks, and therefore the height of the seat frameworks is adjusted. The height of the seat framework with different longitudinal widths can be adjusted, so that the vertical height of the seat framework with the movable clamp seat A and the movable clamp seat B can be adjusted when the seat framework rotates, and the clamp can be turned over when clamping the framework with different longitudinal widths; therefore, the problem that the supporting bottom collides with the clamp during overturning due to different longitudinal widths of the seat framework can be avoided.

Description

Technical Field

[0001] This utility model belongs to the technical field of seat frame welding fixtures, specifically relating to a fixing fixture for welding seat frames with a flipping structure. Background Technology

[0002] The frame is a key structural component of the seat assembly. Its main functions are to maintain a correct sitting posture, provide support for the upper body when turning, and provide upper body protection in the event of a collision. The performance of the backrest frame directly affects the strength, rigidity, stability, and even the quality and grade of the seat assembly. The frame is often manufactured by welding, which welds the various components together for use. However, when existing seat frame clamps clamp and fix the frame components, if the clamping force is too great, it can easily cause deformation or damage to the surface of the components. Furthermore, if the frame components are large, it is difficult to use if the distance between the clamping heads on the left and right sides is too close.

[0003] To address this, a fixing clamp for welding a seat frame with a flipping structure, as disclosed in announcement number "CN218426587U", includes a first base, side plates, and a clamp. A connecting structure is provided on one side of the first base, and a second base is provided on one side of the connecting structure. Side plates are mounted on the top of both the first and second bases. A support structure is provided on the inner side of each side plate. A motor is mounted on the top of one side plate, extending to the inner side of the side plate. A clamp is mounted on the side of the motor, with an electric telescopic rod mounted on the top of the clamp. The bottom end of the electric telescopic rod extends into the interior of the clamp, and a pressure block is mounted on the bottom end of the electric telescopic rod. A protective structure is provided on the outer side of the pressure block. By providing the protective structure, an outer shell is secured to the outside of the pressure block. A rubber pad is installed at the bottom of the outer shell. During clamping, the softer rubber pad contacts the surface of the component, preventing deformation or damage due to excessive pressure, thus enhancing the protective performance of the fixing clamp during use.

[0004] However, for the aforementioned fixing clamp for welding seat frames with a flipping structure, although the operator can loosen the fixing bolts on the surface of the second base and then pull the first and second bases to the sides to adjust the distance between the first and second bases, thereby adjusting the distance between the two sets of clamps above, the following obvious defects still exist during use: When clamping seat frames of different sizes, the clamp can only adjust the length distance and cannot adjust according to the longitudinal width of the seat frame. This can easily cause seat frames with a wider longitudinal width to drag and collide with the ground during rotation due to insufficient clamp height. Utility Model Content

[0005] The purpose of this invention is to provide a fixing fixture for welding a seat frame with a flipping structure, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixing clamp for welding a seat frame with a flipping structure, comprising:

[0007] A movable clamping seat A is provided on one side, and a movable clamping seat B is provided on one side for adjusting the width of the clamping spacing laterally. Both movable clamping seats A and B are provided on one side of their ends for adjusting the height of the seat frame of different lengths. A central fixing clamp for clamping and flipping the seat frame is rotatably provided at the center of the upper inner side of the lifting plate. Adjusting clamps for adjusting the clamping spacing of seat frames of different lengths are provided at the front and rear ends of the central fixing clamp. A servo motor for driving the central fixing clamp to flip the seat frame is provided on the other side of the lifting plate.

[0008] Preferably, the movable clamp seat A has guide support grooves on both the front and back of one side for guiding the spacing adjustment, which is beneficial for extending the support during the lateral spacing adjustment of the clamp.

[0009] Preferably, one side of the movable clamp seat B is provided with an extension support plate that can be movably inserted into the guide support groove for telescopic guidance and support, thereby enhancing the stability of the clamp when the lateral spacing is adjusted.

[0010] Preferably, a mounting cavity is provided at the center of one side of the movable clamp seat B, and a cylinder A is provided in the mounting cavity for adjusting the lateral clamping distance by being fixedly connected to one side of the movable clamp seat A, thereby realizing the lateral adjustment of the clamp.

[0011] Preferably, both the movable clamp seat A and the movable clamp seat B have a lifting cavity at their bottom, and each lifting cavity is equipped with a cylinder B that fixes the end side of the movable clamp seat A and the movable clamp seat B to adjust the clamp height.

[0012] Preferably, the end of the central fixing clamp is provided with a cylinder C, one end of which extends into the clamping cavity of the central fixing clamp and is connected to a rubber protective clamp plate, which can adjust the longitudinal width of the seat frame clamping to ensure the stability of the flipping.

[0013] Preferably, the end of the adjusting clamp is provided with a clamping cylinder, one end of which moves through the clamping cavity inside the adjusting clamp and is connected to a rubber clamping plate, which can achieve the effect of clamping and protecting the seat frame during the clamping process.

[0014] Preferably, the center fixing clamp is provided with adjusting cylinders at both the front and rear of one side. One end of the adjusting cylinder is fixed to one side of the adjusting clamp through a connecting block to realize the adjustment of the longitudinal clamping width, so as to stably clamp the seat frame with different longitudinal widths.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This fixing fixture for welding seat frames with a flipping structure has a lifting plate that is raised and lowered by cylinder B at the ends of the movable clamping fixture A and movable clamping fixture B, and a central fixing fixture that is rotated at the corresponding position of the lifting plate. When the seat frame needs to be flipped after being clamped and fixed by the central fixing fixture, the height of the lifting plate is adjusted by raising and lowering cylinder B according to the different longitudinal widths of the seat frame. This allows seat frames with different longitudinal widths to be adjusted to different heights, so that the vertical height of the seat frame relative to the movable clamping fixture A and movable clamping fixture B can be adjusted when rotating. This ensures that the fixture can flip when clamping frames with different longitudinal widths, thus avoiding the problem of the bottom of the seat frame hitting the fixture during flipping due to different longitudinal widths.

[0016] The central fixing clamp is rotated by a servo motor on one side of the lifting plate. The two ends of the central fixing clamp are adjusted by adjusting cylinders. The adjusting clamps are equipped with rubber clamps attached to the clamping cylinders. When clamping a seat frame with a larger longitudinal width, the adjusting cylinders push the adjusting clamps at both ends of the central fixing clamp to extend outward, thereby adjusting the longitudinal clamping width of the central fixing clamp. This allows the central fixing clamp to clamp seat frames with different longitudinal widths. The adjustment of the clamping distance ensures that seat frames with different longitudinal widths maintain a certain degree of firmness and stability during rotation after being clamped, avoiding the phenomenon of loosening and detachment that is easy to occur when the clamping distance is too small.

[0021] 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.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a fixing clamp for welding a seat frame with a flipping structure, comprising:

[0023] A movable clamping seat A1 has a movable clamping seat B2 on one side for lateral adjustment of the clamping spacing. After the seat frame is clamped and fixed, movable clamping seats A1 and B2 provide stable support. Each end of movable clamping seats A1 and B2 has a lifting plate 3 for height adjustment during the flipping of seat frames of different lengths. The lifting plate 3 is vertically positioned on one side of the ends of movable clamping seats A1 and B2 to provide stable support for the seat frame after clamping, ensuring stability during flipping. A central fixing clamp 4 is rotatably provided at the upper center of the inner side for clamping and flipping the seat frame. It can clamp and fix the center position of the longitudinal side of the seat frame. The front and rear ends of the central fixing clamp 4 are provided with adjusting clamps 5 for adjusting the clamping distance of seat frames of different lengths. The longitudinal width of the seat frame clamping can be adjusted to make the clamping more secure and stable. The other side of the lifting plate 3 is provided with a servo motor 6 for driving the central fixing clamp 4 to flip the seat frame, and driving the clamped seat frame to flip and then weld.

[0024] The movable clamping fixture A1 has guide support grooves 7 on both the front and back of one side for adjusting the spacing. The movable clamping fixture B2 has an extension support plate 8 on one side corresponding to the guide support grooves 7, which can be inserted into the guide support grooves 7 for telescopic guidance and support. The extension support plate 8 allows the movable clamping fixture A1 and movable clamping fixture B2 to adjust the lateral clamping spacing, so as to clamp and fix seat frames of different lengths. The center of one side of the movable clamping fixture B2 has a mounting cavity 9, which allows the extension support plate 8 to telescopically extend and retract within the mounting cavity 9 for guiding support during spacing adjustment. The mounting cavity 9 has a cylinder A10 fixedly connected to one side of the movable clamping fixture A1 for adjusting the lateral clamping spacing, so as to adjust the lateral clamping spacing of the welding fixture. The bottom of both the movable clamping fixture A1 and movable clamping fixture B2 has a lifting cavity 11. The lifting cavity 11 has a cylinder B12 inside which fixes the end sides of the movable clamping fixture A1 and movable clamping fixture B2, so as to adjust the height of the welding fixture.

[0025] The center fixing clamp 4 is equipped with a cylinder C13 at one end. One end of the cylinder C13 passes through the clamping cavity of the center fixing clamp 4 and is connected to a rubber protective clamp 14. It can clamp and fix the center position of the seat frame edge and provide surface clamping protection. The adjusting clamp 5 is equipped with a clamping cylinder 15 at one end. One end of the clamping cylinder 15 moves through the clamping cavity inside the adjusting clamp 5 and is connected to a rubber clamp 16. It can adjust the longitudinal clamping distance of the seat frame to enhance the stability during flipping. The center fixing clamp 4 is equipped with adjusting cylinders 17 at both the front and rear of one side. One end of the adjusting cylinder 17 is fixed to one side of the adjusting clamp 5 through a connecting block. It can adjust and clamp the adjusting clamp 5 according to the longitudinal width of the seat frame to enhance the firmness during flipping.

[0026] Specifically, in use, the seat frame to be welded is first placed horizontally on the movable clamp seat A1 and movable clamp seat B2, so that the two ends of the seat frame are placed in the clamping cavity of the central fixed clamp 4. The cylinder C13 is used to push the rubber protective clamp plate 14 to clamp and fix the two ends of the seat frame in the clamping cavity. According to the length of the seat frame, the cylinder A10 is used to adjust the spacing of the movable clamp seat A1 and movable clamp seat B2 to different lengths horizontally, so that the central fixed clamp 4 can clamp seat frames with different horizontal lengths. Then, according to the longitudinal width of the seat frame, the adjusting cylinder 17 is used to push the adjusting clamps 5 at both ends of the central fixed clamp 4 to extend outward. The outward extension of the adjusting clamps 5 can accommodate seat frames with different longitudinal widths. Long-distance clamping and fixing are performed, thereby using the clamping cylinder 15 to push the rubber clamping plate 16 to clamp different seat frames at a large distance, so as to ensure that the seat frames are more firm and stable during the flipping and welding process. After the fixture clamps the seat frame with a longer longitudinal width, the cylinder B12 can be used to adjust the height of the lifting plate 3 on the moving fixture seat A1 and the moving fixture seat B2, so that the seat frame with a longer longitudinal width is adjusted to the vertical height of the moving fixture seat A1 and the moving fixture seat B2. In this way, seat frames with different longitudinal widths and transverse lengths can be clamped, fixed, flipped and welded. After the seat frame is clamped, the servo motor 6 drives the seat frame clamped in the central fixed fixture 4 to flip and use the welding machine to perform welding work.

[0027] 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.
