Description

Technical Field

[0001] This utility model relates to the field of automotive rubber and plastic sealing strip assembly technology, and in particular to an assembly fixture for automotive rubber and plastic sealing strips. Background Technology

[0002] Vehicle body seals are typically made of rubber and plastic, with rubber and plastic sealing strips commonly used in doors, trunks, and roofs. In actual production, manual or automated operation can be chosen depending on the working conditions and output. Regardless of the degree of automation, the core mechanism of the assembly device, requiring both flexibility and sufficient assembly force, remains a technical challenge. Currently, most fixtures can only achieve assembly through forced compaction by shaped wheels, inevitably leading to defects such as deformation and breakage. Conversely, insufficient assembly force poses a risk of rubber and plastic sealing strips detaching. Therefore, technological innovation is urgently needed to overcome problems such as deformation, breakage, and detachment during assembly, thereby improving the quality of assembled products and increasing production efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide an assembly fixture for automotive rubber and plastic sealing strips to solve problems such as deformation, damage, and detachment during the assembly process of rubber and plastic sealing strips.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fixture for assembling automotive rubber and plastic sealing strips includes a handle portion, a pin support plate, and a roller portion. The roller portion is movably mounted on the handle portion. The pin support plate is fixed to the handle portion by screws. The handle portion includes a rubber layer, a steel cylinder, a spring, a sliding column, and a sliding bearing. The spring, a compression spring, presses against the sliding column, which can move left and right via the sliding bearing. A rubber layer is provided on the outer surface of the steel cylinder. The roller portion includes a fixing bolt, a polyurethane sleeve, and... The roller body comprises a roller body, a groove, a bearing, a roller shaft, and a roller bracket. The polyurethane sleeve is disposed on the circumferential surface of the roller body. The roller body is rotatably mounted on the roller shaft via the bearing. The roller shaft is fixedly mounted on the roller bracket using fixing bolts. The roller bracket and the sliding column are fixedly connected together by threads. Grooves are provided on both sides of the roller body, and self-locking grooves are provided on the side walls of the grooves. Two pin support plates are provided, located on both sides of the roller bracket. Each pin support plate is provided with a self-locking pin, which extends into the groove.

[0006] The aforementioned automotive rubber and plastic sealing strip assembly fixture has an adjusting block in the inner cavity of the right end of the steel cylinder, and the adjusting block is connected to the inner wall of the steel cylinder by a thread.

[0007] In the aforementioned automotive rubber and plastic sealing strip assembly fixture, the self-locking grooves are evenly distributed on the side wall of the groove, and the self-locking grooves are semi-circular with a diameter that matches the diameter of the self-locking pin.

[0008] The aforementioned automotive rubber and plastic sealing strip assembly fixture has elongated holes on both sides of the roller bracket.

[0009] This utility model has the following advantages:

[0010] The roller part of this invention has a groove on the roller body, and a self-locking groove on the side wall of the groove. When not in use, the self-locking pin is embedded in the self-locking groove. In use, when the force applied to the handle is less than the rated force, the spring is not compressed, the self-locking pin is embedded in the self-locking groove, and the roller body does not rotate. At this time, the assembly force is insufficient, and assembly work cannot be performed; otherwise, the rubber and plastic strip may easily detach. When the force applied to the handle is greater than the rated value, the spring is compressed, the roller body moves relative to the handle, the self-locking pin disengages from the self-locking groove, and the roller body rotates. At this time, the assembly force is sufficient, and under the action of the spring, the output of the assembly force is flexible, preventing damage to the rubber and plastic strip caused by a large instantaneous assembly force. This invention, through control of the assembly force, avoids problems such as deformation, breakage, and detachment of the rubber and plastic sealing strip caused by improper force application during assembly.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] This utility model relates to an assembly fixture for automotive rubber and plastic sealing strips, such as... Figure 1 and Figure 2 As shown, the device includes a handle portion 1, a pin support plate 2, and a roller portion 3. The handle portion 1 includes a rubber layer 1-1, a steel cylinder 1-2, a spring 1-4, a sliding column 1-5, and a sliding bearing 1-6. The spring 1-4, sliding column 1-5, and sliding bearing 1-6 are housed within the inner cavity of the steel cylinder 1-2. The spring 1-4 is a compression spring, pressing against the sliding column 1-5. The sliding column 1-5 can move left and right via the sliding bearing 1-6. A rubber layer 1-1 is provided on the outer surface of the steel cylinder 1-2. Two pin support plates 2 are provided; their right ends are fixed to the steel cylinder 1-2 with screws 2-1, and their left ends are located on both sides of the roller body 3-3. Each pin support plate 2 has a self-locking pin 2-2. In the initial state of this invention, the self-locking pin 2-2 is embedded in the self-locking groove 3-4-1. The roller portion... 3 includes a fixing bolt 3-1, a polyurethane sleeve 3-2, a roller body 3-3, a groove 3-4, a bearing 3-5, a roller shaft 3-6, and a roller bracket 3-7. The polyurethane sleeve 3-2 is disposed on the circumferential surface of the roller body 3-3. The roller body 3-3 is rotatably mounted on the roller shaft 3-6 via the bearing 3-5. The roller shaft 3-6 is fixedly mounted on the roller bracket 3-7 using the fixing bolt 3-1. The roller bracket 3-7 is threadedly connected to the sliding column 1-5. Grooves 3-4 are provided on both sides of the roller body 3-3, and self-locking grooves 3-4-1 are provided on the side walls of the grooves 3-4. Two pin support plates 2 are provided, located on both sides of the roller bracket 3-7 respectively. Each pin support plate 2 is provided with a self-locking pin 2-2, which extends into the groove 3-4.

[0018] This utility model discloses an assembly fixture for automotive rubber and plastic sealing strips. An adjusting block 1-3 is provided in the inner cavity of the right end of the steel cylinder 1-2. The adjusting block 1-3 is connected to the inner wall of the steel cylinder 1-2 by a thread. By rotating the adjusting block 1-3, the elastic force of the spring 1-4 can be adjusted by moving the adjusting block 1-3 left and right.

[0019] This utility model discloses an assembly fixture for automotive rubber and plastic sealing strips. The roller bracket 3-7 has elongated holes 3-7-1 on both sides to accommodate self-locking pins 2-2, allowing it to move left and right.

[0020] This utility model relates to an assembly fixture for automotive rubber and plastic sealing strips. The working principle is as follows:

[0021] In the non-use state, the self-locking pin 2-2 is embedded in the self-locking groove 3-4-1. When in use, if the force applied to the handle 1 is less than the rated force, the spring 1-4 will not be compressed, and the self-locking pin is embedded in the self-locking groove. The roller body 3-3 will not rotate. At this time, the assembly force is insufficient, and assembly work cannot be performed. Otherwise, the rubber strip may easily fall off. When the force applied to the handle 1 is greater than the rated value, the spring 1-4 is compressed, the roller body 3-3 moves relative to the handle 1, the self-locking pin 2-2 comes out of the self-locking groove 3-4-1, and the roller body 3-3 rotates. At this time, the assembly work can be performed with sufficient assembly force. At the same time, under the action of the spring 1-4, the force applied to the handle is flexibly transmitted to the roller body.
