[0002] In the automotive manufacturing industry, the integrated molded rear compartment assembly is an important component of the vehicle body structure, mainly including the rear bulkhead, luggage compartment frame, and rear floor assembly. The assembly precision of the integrated molded rear compartment assembly directly affects the safety and aesthetics of the entire vehicle.

[0003] When installing the integrated rear compartment assembly, in order to ensure stability during installation, manual positioning and simple clamps are usually used for clamping and fixing. Although this can achieve the fixing effect, there are some problems in actual use.

[0004] During clamping, multiple clamps are required to fix both sides of the integrated rear compartment assembly one by one, which is cumbersome, time-consuming, and difficult to meet the requirements of high efficiency. In addition, traditional clamps are generally rigid clamps with fixed contact surface shapes, but the surface of the rear compartment assembly is curved, which results in fewer clamping contact points and instability.

[0005] To address this issue, an assembly positioning and clamping device for an integrated molded rear compartment assembly is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an assembly positioning clamping device for an integrated molded rear compartment assembly, which aims to improve the problems of cumbersome clamping operation, low efficiency and insufficient stability caused by poor adaptability of rigid clamps to curved surfaces in the prior art.

A positioning sleeve is slidably connected to the outer wall of the guide plate.

[0009] As a further description of the above technical solution:

[0010] The clamping mechanism further includes a fixing component, which includes a clamping plate fixedly connected to the right surface of the positioning sleeve.

A first clamping block is fixedly connected to the right surface of the first slider. A second sliding groove is formed on the right surface of the first clamping block, and a second slider is slidably connected to the inner wall of the second sliding groove. A second clamping block is fixedly connected to the right surface of the second slider.

[0011] As a further description of the above technical solution:

[0012] The lifting assembly includes a support block, which is fixedly connected to the upper surface of the guide plate. A hydraulic rod is provided on the lower surface of the support block, and a movable block is fixedly connected to the lower surface of the hydraulic rod.

[0013] As a further description of the above technical solution:

[0014] The screw passes through and is rotatably connected to the inner surface of the fixed block, and the connecting block is slidably connected to the lower surface of the support platform.

[0015] As a further description of the above technical solution:

[0016] The guide plate is slidably connected to the inner surface of the support platform.

[0017] As a further description of the above technical solution:

[0032] 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.

[0033] Reference Figures 1-3 An embodiment of this utility model provides an assembly positioning clamping device for an integrated molded rear cabin assembly, including a support platform 1 for supporting the overall device. Support legs are fixedly connected to the four corners of the lower surface of the support platform 1. A fixing block 2 is fixedly connected to the front of the lower surface of the support platform 1. A clamping mechanism for clamping and fixing the molded rear cabin assembly is provided on the outside of the support platform 1. A lifting component is provided above the support platform 1. The lifting component can control the height of the clamped and fixed rear cabin assembly to suit different installation heights.

[0034] Reference Figures 1-2The clamping mechanism includes a drive assembly for moving the drive device. The drive assembly includes a motor 31, which is mounted on the front surface of the fixed block 2. The output shaft of the motor 31 is fixedly connected to a screw 32. The motor 31 and the screw 32 are existing technologies and can be implemented by those skilled in the art. As they are existing technologies, they will not be described in detail in this case. The outer wall of the screw 32 is threadedly connected to a connecting block 33. When the screw 32 rotates, it will drive the connecting block 33 to move in the back-and-forth direction. One end of the connecting rod 34 is hinged to the rear surface of the connecting block 33, and the other end of the connecting rod 34 is hinged to a guide plate 35. When the connecting block 33 moves back and forth, it will squeeze the connecting rod 34 to make it swing, which will drive the guide plate 35 to move in the left and right direction. The outer wall of the guide plate 35 is slidably connected to a positioning sleeve 36, which moves longitudinally.

[0035] Reference Figures 2-4 The clamping mechanism also includes a fixing component for clamping and fixing the rear compartment assembly. The fixing component includes a clamping plate 41, which is fixedly connected to the right surface of the positioning sleeve 36. The positioning sleeve 36 and the clamping plate 41 move synchronously. A first sliding groove 42 is provided on the right surface of the clamping plate 41. A first slider 43 is slidably connected to the inner wall of the first sliding groove 42. A first clamping block 44 is fixedly connected to the right surface of the first slider 43. During clamping, the first slider 43 slides along the trajectory of the first sliding groove 42, which in turn causes the first clamping block 44 to tilt. A second sliding groove 45 is provided on the right surface of the first clamping block 44. A second slider 46 is slidably connected to the inner wall of the second sliding groove 45. A second clamping block 47 is fixedly connected to the right surface of the second slider 46. During clamping, the second slider 46 slides along the trajectory of the second sliding groove 45, which in turn causes the second clamping block 47 to tilt, so as to fit the clamping position of different shapes and ensure the stability of clamping.

[0036] Reference Figures 2-4 The screw 32 passes through and is rotatably connected to the inner surface of the fixed block 2, which provides support for the screw 32. The connecting block 33 is slidably connected to the lower surface of the support platform 1 and moves in the front-to-back direction. The guide plate 35 passes through and is slidably connected to the inner surface of the support platform 1 and moves in the left-to-right direction. Both the first slide groove 42 and the second slide groove 45 are arc-shaped. The right end of the second clamping block 47 is made of rubber, and the contact surface between the second clamping block 47 and the rear compartment assembly is made of rubber to ensure the rear... The stability of the cabin assembly during clamping and the prevention of excessive clamping force that could cause wear on the surface of the rear cabin assembly and affect the quality of the finished product are ensured by the following: the connecting rod 34, guide plate 35, positioning sleeve 36, and fixing components are provided in two sets. The two sets of connecting rod 34, guide plate 35, positioning sleeve 36, and fixing components are symmetrically distributed on the left and right sides of the center line of the support platform 1, which can clamp and fix the rear cabin assembly from both sides at the same time, ensuring the stability during clamping. When the connecting block 33 moves back and forth, it will drive the guide plates 35 on both sides to move closer or open synchronously.

[0037] Reference Figures 1-3 The lifting assembly includes a support block 51, which is fixedly connected to the upper surface of the guide plate 35. A hydraulic rod 52 is provided on the lower surface of the support block 51, and a moving block 53 is fixedly connected to the lower surface of the hydraulic rod 52. The hydraulic rod 52 is existing technology and can be implemented by those skilled in the art. After the hydraulic rod 52 is activated, it can drive the moving block 53 to move longitudinally. The moving block 53 is fixedly connected to the left surface of the positioning sleeve 36. The moving block 53 and the positioning sleeve 36 will move synchronously to achieve the height adjustment of the rear cabin assembly.

[0038] Working principle: First, place the rear compartment assembly between the two sets of fixing components and hold the rear compartment assembly in place. Then, start the motor 31. The motor 31 drives the screw 32 to rotate, which in turn drives the connecting block 33 to move forward. The forward-moving connecting block 33 pulls the two sets of connecting rods 34 and drives the guide plates 35 on both sides and the fixing components to move closer together. The fixing components on both sides will clamp the rear compartment assembly. When clamping, when the clamping plate 41 is close to the rear compartment assembly, the first clamping block 44 slides along the arc-shaped trajectory of the first slide groove 42 through the first slider 43, and the second clamping block 47 slides along the arc-shaped trajectory of the second slide groove 45 through the second slider 46. This allows the second clamping block 47 to adapt to the shape of the rear compartment assembly, ensuring the stability and fit of the clamping. The rubber material of the second clamping block 47 further protects the surface of the rear compartment assembly and avoids wear during the clamping process.

[0039] If the installation height needs to be adjusted, activate the hydraulic rods 52 on both sides to move the moving block 53, positioning sleeve 36, fixing components and rear compartment assembly up and down. When the appropriate height is reached, stop the hydraulic rods 52.

[0040] When installation is complete, start motor 31 drives screw 32 to reverse, which in turn drives connecting block 33 to move backward, squeezing connecting rod 34 so that it drives guide plates 35 on both sides and fixing components to open, thus releasing the clamp on the rear compartment assembly.

[0041] 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.
