Description

Technical Field

[0001] This application relates to the field of automotive body processing technology, and more specifically, to an automotive body trimming device. Background Technology

[0002] In the prior art, for example, a trimming mold for processing automobile body panels disclosed in CN216262930U includes a base, a fixed frame fixedly mounted on the top of the base, a cylinder mounted on the surface of the fixed frame, a connecting plate fixedly mounted on the bottom of the cylinder, a positioning plate mounted inside the connecting plate, a first movable plate and a second movable plate movably mounted inside the base, a first cutting tool fixedly mounted on the bottom of the connecting plate, a connecting rod movably mounted through the connecting plate on the top of the first and second movable plates, and a first limiting rod and a second limiting rod fixedly mounted on the surface of the base.

[0003] This solution uses a first limiting rod and a second limiting rod to restrict the clamping of the four sides of the car body, thereby determining the processing position of the car body and the cutting position of the four sides of the car body. This also determines the position of the burrs cut off from the car body, thus achieving the effect of convenient burr removal.

[0004] However, in this design, when the first cutter cuts the burrs on the side of the car body, it uses the method of cutting off all the burrs on the side of the body at the same time. This design puts a large load on the cylinder and causes great damage to the cutting edge, which can easily lead to curling or chipping at the cutting edge. Utility Model Content

[0005] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes an automotive body trimming device, which aims to improve the problems of high cylinder load and easy damage to the cutting tools in the existing automotive body trimming device.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] like Figures 1-5 As shown, an automotive body trimming device according to an embodiment of this application includes a U-shaped frame 1, wherein a support platform 2 is fixedly connected to the bottom of the U-shaped frame 1, and a lifting platform 3 is lifted and connected to the top of the U-shaped frame 1. A plurality of strip-shaped cutters 4 are fixedly connected to the bottom side of the lifting platform 3. The strip-shaped cutters 4 are inclined and respectively cooperate with the peripheral side of the support platform 2 with clearance.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, a support column 21 is fixed to the bottom side of the support platform 2. The support column 21 is fixed to the inner bottom of the C-shaped frame 1. This design allows a gap to be formed between the support platform 2 and the inner bottom of the C-shaped frame 1, which facilitates the cleaning of residues that fall onto the C-shaped frame 1 during the cutting process.

[0026] It should be noted that a lifting component 31 is fixedly connected between the top of the lifting platform 3 and the inner top of the U-shaped frame 1. The lifting component 31 can be an existing technology such as a hydraulic cylinder with telescopic function. The height of the lifting platform 3 relative to the support platform 2 can be changed by the telescopic change of the lifting component 31 itself.

[0027] like Figure 1 and Figure 3 As shown, a fixed film chamber 32 is elastically connected to the bottom side of the lifting platform 3. Multiple guide rods 321 are uniformly fixed to the top side of the fixed film chamber 32. The multiple guide rods 321 slide through the lifting platform 3. Springs 322 are sleeved on the guide rods 321. The two ends of the springs 322 abut against the lifting platform 3 and the fixed film chamber 32, respectively. It can be seen that when the lifting platform 3 moves the fixed film chamber 32 towards the support platform 2, after the fixed film chamber 32 abuts against the car body to be cut, the fixed film chamber 32 will be resisted and elastically retract into the lifting platform 3. That is, the fixed film chamber 32 has an elastic pressing effect on the car body on the support platform 2, which can prevent the car body from being damaged by rigid compression.

[0028] It should be noted that, as Figure 4 As shown, a recessed positioning part 323 is provided on the bottom side of the film-fixing chamber 32. It can be understood that the recessed positioning part 323 can fit with the car body to be cut and position the car body.

[0029] Furthermore, a storage compartment 33 is provided on the bottom side of the lifting platform 3, and the film fixing compartment 32 is adapted to the storage compartment 33, so that the film fixing compartment 32 can elastically retract relative to the lifting platform 3 after it comes into contact with the car body.

[0030] like Figure 1 and Figure 5 As shown, multiple strip cutters 4 are respectively arranged on the periphery of the film-fixing chamber 32. The two adjacent strip cutters 4 are arranged in an undulating manner. Specifically, taking the clockwise direction as an example, if one strip cutter 4 is uphill, then the next strip cutter 4 is downhill.

[0031] Among them, the top end of the strip cutter 4 is fixedly connected to the mounting plate 41, the strip cutter 4 extends out of the outer side of the mounting plate 41, the two ends of the mounting plate 41 are fixedly connected to the positioning seats 42, the positioning seats 42 are fixedly connected to the positioning rods 43, and the positioning rods 43 are fixedly connected to the lifting platform 3.

[0032] Understandably, by setting the strip cutter 4 to an inclined position, the strip cutter 4 gradually cuts the positioned and fixed car body during its descent. The cutting point moves as the strip cutter 4 descends. This avoids the strip cutter 4 cutting all the burrs simultaneously, reducing the load on the lifting component 31. At the same time, the inclined strip cutter 4 and the burrs make inclined contact, reducing the occurrence of chipping or curling at the cutting edge of the strip cutter 4 and improving the service life of the strip cutter 4.

[0033] Meanwhile, since the strip-shaped cutter 4 extends from the outer side of the mounting plate 41, it is understandable that during the cutting process, if there are burrs on the car body, the burrs will be pressed by the mounting plate 41 and gradually fall downwards, which further helps to remove the burrs from the body.

[0034] It should be noted that the specific models and specifications of the lifting component 31, spring 322 and bar-shaped cutter 4 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0035] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
