Description

Technical Field

[0001] The utility model relates to the field of automobile assembly auxiliary equipment, in particular to a positioning device for assembling a vehicle windshield wiper. Background Art

[0002] Cars are usually designed with two front wipers. In rainy and snowy weather, the two front wipers can be made to swing back and forth synchronously on the front windshield to wipe off the rain on the front windshield. When installing the front wiper of a car, the wiper arm with the wiper blade assembly is generally pre-installed on the wiper motor, and then the fixing nut is pre-installed, and finally the fixing nut is tightened using a torque tool.

[0003] After installation, it is necessary to ensure that the wiper blade is parked at the lower edge of the front windshield in a free state. In order to ensure the installation position of the wiper blade, the traditional method is for employees to manually control the position of the wiper arm when tightening the nut, which requires a high level of personal experience of employees. In addition, when tightening, the wiper arm is subjected to friction in the direction of the torque. If no reaction force is applied, the wiper arm will tend to rotate in the direction of the torque, making it difficult to ensure the consistency of the installation of the two wiper arms, and the installation accuracy is low.

[0004] In addition, during the assembly process, the distance between the two wipers is not easy to control, which makes the working arc range of the wiper blade uncertain when the wiper is used later, and in serious cases, operation interference may occur.

[0005] For example, the existing patent 202220406589.5 - Wiper motor output arm assembly positioning tooling does not clearly disclose the technical inspiration for solving the above-mentioned problems.

[0006] Therefore, in order to better improve the above problems, an auxiliary tool is needed to assist in the installation operation of the main and auxiliary wipers. Utility Model Content

[0028] The specific implementation methods of the present utility model will be further explained in detail below by describing the optimal embodiments with reference to the accompanying drawings.

[0029] A positioning device for assembling a vehicle wiper. The positioning device disclosed by the utility model is mainly used to limit the assembly interval between a main wiper and an auxiliary wiper, so as to ensure the accuracy of the relative assembly position of the main wiper and the auxiliary wiper.

[0030] Specifically, the positioning device disclosed in the utility model is mainly used for the assembly and positioning operation of the front wiper of a vehicle.

[0031] In the utility model, the positioning device mainly comprises a positioning tool, and the main body of the positioning tool is made of nylon material; it plays a good protective role and prevents the positioning tool from damaging the vehicle.

[0032] At the same time, the positioning tool in the utility model includes a positioning block 1, which is the main structure of the positioning tool, and a first positioning groove 2 and a second positioning groove 3 are arranged at intervals on the positioning block 1; the first positioning groove 2 and the second positioning groove 3 are respectively used for the installation and positioning of the main wiper and the auxiliary wiper, because the relative positions of the first positioning groove 2 and the second positioning groove 3 are already defined, thereby the relative interval between the main and auxiliary wipers can be defined; and by positioning the front auxiliary wiper arm and the front main wiper blade, the working arc range and positioning accuracy of the wiper blade of the front auxiliary wiper arm and the front main wiper blade during operation and return can be ensured.

[0033] At the same time, in the utility model, the positioning block 1 is also provided with an installation through hole 6, and the installation through hole 6 is interconnected with the second positioning groove 3; the setting of the installation through hole 6 is convenient for the placement of the nut and avoids interference between the positioning tool and the placement of the corresponding nut; at the same time, the second positioning groove 3 is interconnected with the installation through hole 6; such a setting makes it convenient for the auxiliary wiper installation position to pass through the second positioning groove 3 and be arranged at the installation through hole 6, which is convenient for subsequent installation operations.

[0034] Furthermore, in the utility model, the positioning block 1 includes a basic block 11, and an extension block 12 is provided on the basic block 11; the basic block 11 and the extension block 12 constitute the main structure of the positioning block 1, and the width of the extension block 12 is smaller than that of the basic block 11, the first positioning groove 2 is arranged on the extension block 12, and the second positioning groove 3 is arranged on the basic block 11; the first positioning groove 2 is mainly connected to the main wiper arm on the main wiper, and the extension block 12 is clamped on the main wiper through the first positioning groove 2; the basic block is clamped on the auxiliary wiper through the second positioning groove 3; at the same time, by limiting the directions of the first positioning groove 2 and the second positioning groove 3, the relative positions of the main wiper and the auxiliary wiper can be well controlled.
