The operator inserts the sealing strip into the corresponding sealing groove and then manually tightens the sealing strip. If the operation is completely manual, it is difficult to ensure the installation quality of the sealing strip, which may cause problems such as loose sealing and falling off in the subsequent finished products. For this reason, some simple tooling for assembling automobile sealing strips has appeared in the prior art, such as a push rod with a circular arc surface on the top, which is used to assist the operator to tighten the sealing strip and improve the assembly quality.

[0003] In the process of implementing the present utility model, the inventors found that there are at least the following problems in the prior art:

[0004] The existing sealing strip assembly tooling has a simple structure and single function. After the sealing strip is assembled, there are still problems such as poor flatness and uneven pressing force, which are of limited help to the assembly work. Therefore, how to optimize the structure of the sealing strip assembly tooling and effectively improve the assembly quality is a problem that needs to be solved. Utility Model Content

[0005] The embodiment of the utility model provides an automobile sealing strip assembly tool (or an automobile sealing strip auxiliary belt pressure roller assembly tool) to solve the problems of poor sealing strip flatness and uneven pressing force after the sealing strip assembly tool is used in the prior art, thereby improving the sealing strip assembly quality.

[0006] To achieve the above-mentioned purpose, an embodiment of the utility model provides an automobile sealing strip assembly tool, including: a roller bracket, a handle, and a cylindrical roller; the handle is a long cylindrical structure, and the roller bracket is a U-shaped structure with an open top; the roller is located in the groove of the roller bracket, the roller is hinged to the roller bracket through a roller shaft, and the top of the roller protrudes from the top of the roller bracket; the bottom of the roller bracket is connected to the top of the handle.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 , Figure 2 As shown, an embodiment of the utility model provides an automobile sealing strip assembly tool, comprising: a roller bracket 10, a handle 4, and a cylindrical roller 1; the handle 4 is a long cylindrical structure, and the roller bracket 10 is a U-shaped structure with an open top; the roller 1 is located in the groove of the roller bracket 10, the roller 1 is hinged to the roller bracket 10 through a roller shaft 11, and the top of the roller 1 protrudes from the top of the roller bracket 10; the bottom of the roller bracket 10 is connected to the top of the handle 4.

[0024] In order to solve the above-mentioned problems, in this technical solution, a roller 1 is set at the top of the handle 4. When working, the operator holds the handle 4 to make the roller 1 contact with the sealing strip to be assembled. Through the movement of the hand, in the process of the automobile sealing strip assembly tool moving back and forth, the assembly tool is always kept vertically pressed against the sealing strip, so that the roller 1 presses over the sealing strip in a rolling manner, ensuring that the sealing strip is subjected to sufficient pressure and avoiding the tooling from dragging the sealing strip and affecting the flatness, thereby improving the assembly quality and greatly improving the work efficiency. In order to prevent the roller bracket 10 of the U-groove structure from contacting the sealing strip and affecting the operation, it should be ensured that the top of the roller 1 is always higher than the top of the roller bracket 10, so as to ensure that the top of the roller 1 is always in contact with the sealing strip during the sealing strip assembly process.

[0025] Furthermore, the bottom of the roller bracket 10 is connected to a first movable shaft 8, which is a vertically arranged cylindrical structure; the middle part of the handle 4 has an axially arranged opening, the first movable shaft 8 is sleeved in the opening, and the first movable shaft 8 can move up and down along the opening; a compression spring 7 is also arranged in the opening, and the bottom end of the first movable shaft 8 is against the top end of the compression spring 7.

[0026] The provision of the compression spring 7 enables the assembly tool to provide a variable pressing force, which is more conducive to improving the assembly quality.

[0027] Further, such as Figure 3 As shown, the automobile sealing strip assembly tool also includes an axle clamp bracket 3, the bottom of which is connected to the outer side of the top of the handle 4, and the top of the axle clamp bracket 3 is connected to the axle clamp 2; on the side of the roller 1 on the same side as the axle clamp 2, there is also a concave toothed disk 12, the toothed disk 12 includes a plurality of circumferentially uniformly distributed internal teeth, and the tooth shape of each of the internal teeth matches the outer shape of the axle clamp 2; the side wall of the roller bracket 10 is provided with a long groove arranged in the up and down directions, the axle clamp 2 transversely penetrates the long groove and extends into the toothed disk 12; when the roller bracket 10 is located at the topmost limit position, the axle clamp 2 is meshed with the internal teeth located at the bottom of the toothed disk 12.

[0028] Through the cooperation of the compression spring 7, the shaft clamp 2 and the toothed disk 12, the technical solution also realizes the following unique functions: under normal conditions, the elastic force of the compression spring 7 pushes the roller bracket 10 forward, so that the shaft clamp 2 penetrates into the inner teeth at the bottom of the toothed disk 12, and the shaft clamp 2 and the toothed disk 12 are locked with each other. At this time, the roller 1 cannot rotate, and there is no way to smoothly complete the above-mentioned sealing strip assembly work; only when the operator's forward pressing force is large enough so that the pressing force of the roller 1 on the sealing strip reaches the preset value, the compression spring 7 is compressed under the reaction force, and the shaft clamp 2 and the toothed disk 12 are unlocked, the roller 1 can rotate, and the sealing strip assembly work can proceed smoothly. Therefore, the function of this structure is equivalent to a set of clutch devices, which can ensure sufficient pressing force, thereby ensuring stable assembly quality.

[0029] Furthermore, the top of the shaft clamp bracket 3 is a plate-shaped structure, and the inner side surface of the top of the shaft clamp bracket 3 is attached to the outer side surface of the roller bracket 10 .

[0030] The outer side surface of the roller bracket 10 is a plate-like plane, and the top of the shaft clamp bracket 3 is also a plate-like structure. Through the cooperation of the two, the roller bracket 10 can be prevented from accidentally rotating during the process of the roller 1 pressing against the sealing strip, thereby ensuring smooth operation.

[0031] Furthermore, a sleeve 9 is provided between the first movable shaft 8 and the opening. The sleeve 9 can play a good positioning and lubricating role, ensuring that the first movable shaft 8 can move up and down smoothly, and realize the mutual locking or unlocking of the shaft clamp 2 and the toothed disk 12. The sleeve 9 can be in various forms, such as a self-lubricating sleeve made of copper alloy.

[0032] Furthermore, a cylindrical adjusting screw 5 is provided inside the handle 4 , and an internal thread is provided on the side wall of the opening, and the external thread of the adjusting screw 5 matches the internal thread of the opening; the adjusting screw 5 is located below the compression spring 7 .

[0033] According to different vehicle models and sealing strip specifications, different pressing forces are required to achieve the best assembly quality. For this reason, in the present technical solution, an adjusting screw 5 is also provided. By rotating the adjusting screw 5 clockwise or counterclockwise, the deformation degree of the compression spring 7 can be adjusted, thereby changing its elastic force and obtaining different pressing forces (i.e., the force when the shaft clamp 2 and the toothed disk 12 are disengaged from the lock).

[0034] Furthermore, a second movable shaft 6 is provided between the compression spring 7 and the adjusting screw 5 , and the second movable shaft 6 is a vertically arranged cylindrical structure.

[0035] If the compression spring 7 is directly placed on the top end surface of the adjusting screw 5, the compression spring 7 may be twisted when the adjusting screw 5 is rotated, which has an adverse effect on the adjustment work. For this reason, a second movable shaft 6 can be set between the two as a buffer so that the compression spring 7 only produces deformation in the height direction during adjustment. If necessary, a guide block or guide groove can also be set inside the handle 4 to ensure that the second movable shaft 6 only moves in the up and down directions.

[0036] Furthermore, the opening passes through the bottom end surface of the handle 4; the bottom end of the adjusting screw 5 is provided with a hexagonal groove. The size of the hexagonal groove corresponds to the prism size of a commonly used hexagonal wrench, so that the operator can rotate the adjusting screw 5 forward and backward through the opening on the bottom end surface of the handle 4, thereby realizing the adjustment of the pressing force as needed.
