Description

Technical Field

[0001] This utility model relates to the technical field of automobile front pillar processing, specifically a fabric cutting device for automobile front pillar horn hole. Background Technology

[0002] Currently, there are many styles of car front pillars: some are one-piece molded plastic parts, some are leather parts that are formed by gluing a sewn cover to the frame, and some are fabric parts that are formed together by injection molding. Among them, the fabric parts formed by injection molding have a more complicated manufacturing process, and the horn hole needs to be cut into thirty evenly spaced openings to facilitate a more stable and firm application of glue.

[0003] With the rapid development of the automotive industry, vehicle manufacturers are placing increasingly higher demands on the cost of parts and labor. Driven by market demand, the front pillar manufacturing process must continuously improve its stability to enhance product quality and efficiency.

[0004] Traditional fabric cutting for horn-shaped holes relies mainly on manual operation, which is not only inefficient but also prone to low cutting accuracy due to human factors, affecting product quality. During the cutting process, multiple uniform openings need to be cut at the horn-shaped hole of the car's front pillar. Manual operation makes it difficult to ensure consistent accuracy and depth for each cut, which can easily lead to cutting deviation or uneven cutting depth. Utility Model Content

[0005] The purpose of this invention is to provide a fabric cutting device for the horn hole of an automobile front pillar, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fabric cutting device for the horn hole of a car front pillar, comprising a worktable and a support member mounted on the worktable for supporting the car front pillar, further comprising: a mounting frame mounted on the worktable and a pressing mechanism capable of vertically lifting and lowering relative to the mounting frame; a cutting mechanism driven by the pressing mechanism and capable of vertically sliding relative to the worktable, comprising a movable seat, an abutment seat, and a cutting unit fixed on the movable seat, the cutting unit passing through the abutment seat and slidably connected to the abutment seat, an elastic telescopic member being installed between the movable seat and the abutment seat; and a receiving seat facing the cutting unit being mounted on the worktable.

Detailed Implementation

[0017] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0018] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0019] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0020] This utility model aims to provide a cutting device for cutting fabric at the flared holes of a car's front pillar 12. Specifically, the cutting device cuts 30 openings at the flared holes of the car's front pillar 12. The specific implementation method is as follows: Please refer to... Figures 1-5In this embodiment of the present invention, a fabric cutting device for the horn hole of a car front pillar includes a workbench 1 and a support member installed on the workbench 1 for supporting the car front pillar 12. It also includes a mounting bracket 2 installed on the workbench 1 and a pressing mechanism that can be vertically raised and lowered relative to the mounting bracket 2. The cutting mechanism driven by the pressing mechanism and capable of sliding vertically relative to the workbench 1 includes a movable seat 7, an abutment seat 14 and a cutting unit fixed on the movable seat 7. The cutting unit passes through the abutment seat 14 and is slidably connected to the abutment seat 14. An elastic telescopic member 15 is installed between the movable seat 7 and the abutment seat 14. A receiving seat 17 facing the cutting unit is also installed on the workbench 1.

[0021] In this embodiment, the support is designed based on the specific shape of the front pillar 12 of the vehicle to ensure that the front pillar 12 of the vehicle can maintain its stability after being placed on the support.

[0022] After the front pillar 12 of the car is placed on the support, the receiving seat 17 supports the cutting position on the front pillar 12, effectively receiving the cutting position and preventing cutting offset when the cutting unit moves down to perform the cutting action, thus improving cutting accuracy. The pressing mechanism drives the movable seat 7 downward, simultaneously driving the abutment seat 14 downward. When the abutment seat 14 contacts the cutting position on the front pillar 12, it stops moving, and the pressing mechanism continues to drive the movable seat 7 downward, thereby compressing the elastic telescopic member 15 and driving the cutting unit downward to perform the cutting action. Under the elastic force of the elastic telescopic member 15, the cutting unit maintains stable pressure on the cutting position of the front pillar 12, ensuring uniform cutting depth and further improving cutting quality. The car front pillar horn hole fabric cutting device provided by this utility model reduces the tediousness of manual operation and improves work efficiency. After cutting, the pressing mechanism and cutting mechanism can be reset for the next cutting operation. The entire device has a compact structure, is easy to operate, and is highly practical.

[0023] Furthermore, the support includes a plurality of limiting posts 13 fixed on the workbench 1. Each limiting post 13 is equipped with a limiting head 1301 for limiting the side end of the front pillar 12 of the vehicle. The limiting post 13 has a receiving position for receiving the front pillar 12 of the vehicle, thereby achieving bottom support and side end limiting of the front pillar 12 of the vehicle, ensuring that the front pillar 12 of the vehicle remains stable during the cutting process and preventing it from shaking or deviating. The design of the limiting head 1301 can be adjusted according to the side end shape of the front pillar 12 of the vehicle to achieve a more precise limiting effect. This embodiment does not specifically limit this.

[0024] Furthermore, the pressing mechanism includes a guide column 4 fixed on the mounting frame 2, a connecting slide column 6 passing through the mounting frame 2 and slidably connected to the mounting frame 2, one end of the connecting slide column 6 being connected to a reset member that provides a reset force, and the other end being fixed to the movable seat 7; it also includes a driving member for driving the connecting slide column 6 to move downward.

[0025] For example, in one embodiment, the reset member includes a sliding plate 19 slidably sleeved on the guide column 4. One side of the sliding plate 19 is fixed to the connecting sliding column 6, and the other side is connected to a spring 5 installed at the end of the guide column 4. When the driving member drives the connecting sliding column 6 to move down, the spring 5 is continuously stretched. When the cutting is completed, the driving member removes the driving force, and the connecting sliding column 6 is reset under the action of the spring 5.

[0026] In one exemplary embodiment, the driving component includes a gear rotatably mounted on the mounting bracket 2 and a rack fixed on the connecting slide column 6 and meshing with the gear. A handle 3 is fixed on the shaft of the gear. By manually pressing the handle 3, the gear rotates. When the gear rotates, the connecting slide column 6 moves downward through the action of the rack, thereby achieving the driving requirement.

[0027] This embodiment can achieve the driving operation of the drive components without the need for power control, which reduces the energy consumption and cost of the equipment, and also avoids equipment downtime caused by power failure, thereby improving the reliability and stability of the equipment.

[0028] Further, please refer to Figures 2-5 The cutting unit includes a blade holder 16 fixed to the movable seat 7. The blade holder 16 passes through the abutment seat 14 and is slidably connected to the abutment seat 14. Multiple cutting blades 18 are installed on the side of the blade holder 16 facing the worktable 1. The number of blades 18 to be cut is selected according to the number of openings to be cut as needed. This embodiment does not make a specific limitation on this.

[0029] The abutment 14 facing the worktable 1 also has a protrusion that matches the shape of the flared opening of the front pillar 12 of the car, thereby improving the stability of the abutment when the abutment 14 abuts against the front pillar 12 of the car, and at the same time playing a certain role in precise control of the movement of the cutting blade 18.

[0030] To improve the stability of the movement of the movable seat 7, a first slide 9 and a second slide 11 are also fixed on the movable seat 7. The first slide 9 and the second slide 11 are rotatably connected to the first slide rail 8 and the second slide rail 10 fixed on the worktable 1, respectively.

[0031] For preferred options, please refer to [link / reference]. Figure 4The receiving seat 17 has a cutting groove 1701 formed at one end facing the movable seat 7 for inserting a plurality of cutting blades 18, and the side wall of the receiving seat 17 facing the movable seat 7 also has a notch 1702 adapted to the front pillar 12 of the car.

[0032] The cutting groove 1701 can accommodate cutting blades 18 of different sizes to meet the cutting needs of openings of different sizes and shapes. The design of the cutting groove 1701 ensures that the cutting blade 18 remains stable during the cutting process, preventing it from shaking and thus improving cutting accuracy and efficiency. At the same time, the shape of the notch 1702 is adapted to the front pillar 12 of the car, allowing the receiving seat 17 to fit more tightly on the front pillar 12 of the car, further enhancing the stability during cutting.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
