[0023] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the following further details the present utility model in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] Refer to Figures 1-5, A fixing device for an automobile door frame fixture, including a bottom plate 1. A limiting groove is provided on one side of the top of the bottom plate 1. Two clamping plates 7 are symmetrically arranged above the bottom plate 1. A clamping plate 8 is provided on one side of each of the two clamping plates 7. A clamping component connected to the two clamping plates 7 is arranged at the bottom of the bottom plate 1. An adjusting component is respectively arranged on one side of the two clamping plates 7 and the two clamping plates 8. Support legs are provided at the bottom of the bottom plate 1. Specifically, by starting the clamping component, the two clamping plates 7 and the two clamping plates 8 move closer to each other, thereby clamping and positioning the outer sides of both sides of the car door frame, effectively fixing the door frame and adapting to car door frames of different lengths within a certain range. By starting the adjusting component, the pressing plate 13 moves to press and position the top of the car door frame, effectively fixing the top of the car door frame and adapting to car door frames of different thicknesses. By screwing the bolt 10, one mounting plate 9 moves horizontally along the limiting rod 11 to drive the adjacent clamping plate 8 to move, adjusting the distance between the clamping plate 8 and the clamping plate 7 to meet the requirements of adapting to car door frames of different widths, thereby improving the applicability and practicality of the fixing device and reducing the use cost.

[0025] Further, a pressing plate 13 is respectively arranged inside the two clamping plates 7 and the two clamping plates 8. A connecting rod 6 is fixedly installed at the top of the pressing plate 13, and the connecting rod 6 is in an inverted L shape. One end of the connecting rod 6 away from the pressing plate 13 is fixedly installed with a cylinder 12, and the bottom of the cylinder 12 is fixedly installed on one side of the top surface of the adjacent clamping plate 8. Specifically, through the setting of the pressing plate 13, by controlling the cylinder 12 to lower, the connecting rod 6 is driven to move the pressing plate 13 downwards together, so that the bottom of the pressing plate 13 is pressed against the top of the car door frame placed inside the clamping plate 7 and the clamping plate 8 for positioning, thereby effectively fixing the top of the car door frame and adapting to car door frames of different thicknesses within a certain range, improving the practicality of the device. Among them, the cylinder 12 and the motor 2 are both connected to the external controller and power supply, which is the prior art and will not be elaborated here.

[0026] Further, the clamping component includes a motor 2 arranged at the bottom of the bottom plate 1, and one side of the motor 2 is fixedly installed on one side of the bottom of the bottom plate 1 through a bracket. The output end of the motor 2 is drivingly connected to a bidirectional lead screw 3. One end of the bidirectional lead screw 3 away from the motor 2 is rotatably connected to a support plate, and the top of the support plate is fixedly connected to the other side of the bottom of the bottom plate 1. Specifically, through the setting of the bracket and the support plate, the bracket can provide a stable supporting force for the motor 2, making the operation of the motor 2 more stable. The support plate can provide a stable supporting force for the bidirectional lead screw 3 and the nut sleeve 4, etc., making the lateral displacement of the nut sleeve 4 more stable when the bidirectional lead screw 3 rotates.

[0027] Furthermore, the clamping assembly further includes two screw sleeves 4 sleeved on both outer ends of the bidirectional lead screw 3. Fixedly connected to the top of the outer ring of each of the two screw sleeves 4 is a limit block 5 adapted to the limit groove. The top of each of the two limit blocks 5 is fixedly installed with the bottom of the adjacent first clamping plate 7. Specifically, through the arrangement of the screw sleeve 4, by starting the motor 2 to drive the bidirectional lead screw 3 to rotate, the two screw sleeves 4 are immediately caused to generate a lateral displacement approaching each other. The screw sleeve 4 then drives the limit block 5 at the top of the outer ring and causes the adjacent first clamping plate 7 to move. At this time, the mounting plate 9 and the bolt 10, etc. will also drive the second clamping plate 8 to move together, so that the two first clamping plates 7 and the two second clamping plates 8 move closer to each other to clamp and position the outer sides of the car door frame, thereby effectively fixing the door frame and adapting to door frames of different lengths to a certain extent, reducing the use cost, and enhancing the practicability of the device.

[0028] Furthermore, the adjusting assembly includes a bolt 10 arranged on one side of the first clamping plate 7. Fixedly connected to the outer walls on one side of the first clamping plate 7 and the second clamping plate 8 are mounting plates 9. And a screw hole is opened on one side of one of the mounting plates 9. One end of the bolt 10 penetrates through the side wall of the other mounting plate 9 and is threadedly connected to the screw hole in one of the mounting plates 9. A limit rod 11 is sleeved inside one of the mounting plates 9, and one end of the limit rod 11 is fixedly connected to the adjacent side wall of the other mounting plate 9. Specifically, through the arrangement of the bolt 10, personnel can rotate the bolt 10 to make one of the mounting plates 9 generate a horizontal displacement along the limit rod 11, and then drive the adjacent second clamping plate 8 to move, thereby adjusting the distance between the second clamping plate 8 and the first clamping plate 7, and being able to meet the adaptation to door frames of different widths, further enhancing the applicability of the fixing device.

[0029] Furthermore, there are four support legs, and the tops of the four support legs are fixedly connected to the four corners at the bottom of the bottom plate 1. Specifically, through the arrangement of the support legs, multiple support legs can increase the overall stability of the entire device, making the device more stable when operating to fix the car door frame.

[0030] In summary:

[0031] By starting the motor 2 to drive the bidirectional lead screw 3 to rotate, the two screw sleeves 4 are immediately caused to generate a lateral displacement approaching each other. The screw sleeve 4 then drives the limit block 5 at the top of the outer ring and causes the adjacent first clamping plate 7 to move. At this time, the mounting plate 9 and the bolt 10, etc. will also drive the second clamping plate 8 to move together, so that the two first clamping plates 7 and the two second clamping plates 8 move closer to each other to clamp and position the outer sides of the car door frame, thereby effectively fixing the door frame and adapting to door frames of different lengths to a certain extent, reducing the use cost, and enhancing the practicability of the device.

[0032] By controlling the lowering of the cylinder 12, the connecting rod 6 is driven to lower the pressing plate 13 together, so that the bottom of the pressing plate 13 is pressed against the top of the car door frame placed in the first clamping plate 7 and the second clamping plate 8 for positioning. Thus, the top of the car door frame can be effectively fixed and adapted to car door frames of different thicknesses to a certain extent. By turning the bolt 10, one of the mounting plates 9 generates a horizontal displacement along the limiting rod 11, and then drives the adjacent second clamping plate 8 to move, thereby adjusting the distance between the second clamping plate 8 and the first clamping plate 7, which can meet the adaptation to car door frames of different widths, further improving the applicability of the fixing device and the practicality of the device.
