[0002] Cars are a widely used means of land transportation. They have greatly improved people's travel efficiency and convenience, shortened the distance between cities, and promoted economic activities and social interactions. In personal life, cars provide people with a flexible and convenient way of travel. Whether it is commuting to get off work or traveling on weekends, cars are an indispensable partner.

[0003] Automobile sealing strips are a kind of sealing material installed in the door frames, windows, hoods and other parts of the car. They are used to prevent external factors such as water, dust, noise, etc. from entering the car. At the same time, they can also play a role in heat insulation and sound insulation. Automobile sealing strips are usually made of rubber, plastic or synthetic materials. These materials have good elasticity and weather resistance and can adapt to various climatic conditions to ensure good sealing performance. In addition, automobile sealing strips also have a shock-absorbing function, which can reduce the impact force when closing the door and protect the door and body from damage.

[0004] In order to prevent water from accumulating on the inside of the sealing strip, ensure that the sealing strip is firmly installed on the car body, adapt to the different curvatures and angles of the car body, and ensure a good sealing effect, the sealing strip needs to be punched. At present, when automobile sealing strips are produced, they are first punched, then cut to a fixed length, and then assembled. However, in some special cases, such as customized installation, increasing drainage capacity, and replacing old sealing strips, manual punching is required. The current punching method is to first use a ruler to determine the position on the sealing strip, and then the worker controls the sealing strip with one hand and uses a tool to punch with the other hand. However, since the sealing strip is easily deformed, it is difficult to ensure the accurate position and shape of the hole when punching. Utility Model Content

[0005] The technical problem to be solved by the utility model is that it is difficult to ensure the position and shape of the holes when punching holes in the sealing strip manually.

[0006] In order to solve the above problems, the utility model proposes the following technical solutions: an auxiliary positioning device for punching holes in automobile sealing strips, comprising a base; a slide groove 1 is provided on one side of the base, and a slide groove 2 is provided on the other side near the end; a sliding horizontal positioning block is provided in the slide groove 1, a sliding longitudinal positioning block is provided in the horizontal positioning block, a telescopic rod with an end capable of mounting a paintbrush is provided on the side of the longitudinal positioning block close to the middle of the base, a movable plate controlled by a screw rod is provided in the slide groove 2, a fixed plate is provided at one end of the base relative to the slide groove 2, a rotating block is provided in the middle of the movable plate and the fixed plate, a plug-in fixed frame is provided on the side of the two rotating blocks close to the middle of the base, the two fixed frames are respectively inserted at both ends of a shaping rod with the same internal cross-section as the sealing strip, and an anti-movement frame is provided on the shaping rod.

[0007] As an improvement, the base is provided with a scale 1 on one side of the slide 1;

[0008] As an improvement, the transverse positioning block is provided with a slide groove three with a cross-shaped cross section, the longitudinal positioning block is slidably arranged in the slide groove three, and the side of the transverse positioning block away from the middle of the base is provided with a scale two;

[0009] As an improvement, one end of the screw rod is rotatably arranged in the second slide groove, and the other end is threaded through the lower part of the movable plate, and a rotating platform is provided at the end through which the screw rod passes.

[0010] As an improvement, the upper ends of the movable plate and the fixed plate are threadedly connected with a fixing bolt 1 for fixing the rotating block;

[0011] As an improvement, the internal cross-section of the fixed frame and the anti-movement frame is the same as that of the shaping rod;

[0012] As an improvement, a second fixing bolt is provided at the upper end of the anti-movement frame for fixing the position of the anti-movement frame.

[0013] Beneficial effects of the utility model:

[0014] By arranging a rotating block in the middle of the movable plate and the fixed plate, and arranging a fixed frame on one side of the rotating block close to the middle of the base, the two fixed frames are used to fix the sealing strip inserted into the shaping rod, and an anti-movement frame is used to prevent the sealing strip from sliding.
