DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The automobile C-beam is an important component in the vehicle chassis structure, and its cross-sectional shape is similar to a C-shape. After the automobile C-beam is stamped and formed, sharp edges or burrs will appear on its corners. In order to improve its safety during assembly and improve its aesthetic effect, it is necessary to use a grinding device to grind its corners. Since the edge of the C-beam is C-shaped, the contact effect between the grinding wheel and its edge is often poor, affecting the grinding effect. The grinding device provided by the utility model is specially used for the grinding processing of automobile C-beams, and can make the grinding wheel move evenly along the edge of the C-beam to enhance the grinding effect. During the grinding process, it is necessary to transport the processed C-beam to the processing table through a feeding device or manually, and fix the C-beam through a first fixing mechanism and a second fixing mechanism, thereby ensuring the grinding effect of the grinding mechanism.

[0026] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: an edge and corner grinding device for a C-beam of an automobile, comprising a processing table 1, a first slide groove 11 distributed in an array is provided on the processing table 1 and near the rear edge, a first fixing mechanism is provided on the top of the processing table 1 and located at the rear side of the first slide groove 11, a second fixing mechanism is provided at the bottom of the processing table 1 and located below the first slide groove 11, a guide frame 5 is welded and fixed on the processing table 1 and near the front edge, a slide seat 51 is slidably connected to the inner side of the guide frame 5, a grinding mechanism for grinding the edges and corners of the C-beam is provided on the rear side of the slide seat 51, the grinding mechanism comprises a movable frame 6, a grinding wheel 61 and an adjusting wheel 62, an adjusting mechanism connected to the slide seat 51 is provided on the front side of the movable frame 6, and the adjusting mechanism comprises an adjusting rod 7, a sleeve 71 and a second spring 73.

[0027] When grinding the corners of a car C-beam, first, move the car C-beam onto the processing table 1, and fix it on both sides of the car C-beam through the first fixing mechanism and the second fixing mechanism, and make the grinding wheel 61 contact with the edge of the car C-beam to be ground, then, drive the grinding mechanism to move left and right for grinding through the slide 51, and during the movement of the grinding mechanism, the adjusting rod 7, the sleeve 71 and the second spring 73 cooperate with each other, so that the adjusting mechanism adaptively adjusts the grinding mechanism, ensuring that the grinding wheel 61 is always in contact with the edge of the car C-beam, thereby improving the grinding efficiency and grinding effect of the car C-beam.

[0028] like Figure 3 As shown, the first fixing mechanism includes an L-shaped clamp 2 and a pressure plate 21. A connecting rod slidably connected to the L-shaped clamp 2 is provided at the top and near the edge of the pressure plate 21. An adjusting screw 22 is rotatably connected to the top center of the pressure plate 21. The adjusting screw 22 is threadedly connected to the top of the L-shaped clamp 2. A symmetrically distributed first hydraulic cylinder 23 is installed on the processing table 1 and located on the rear side of the L-shaped clamp 2.

[0029] When the first hydraulic cylinder 23 is running, it can drive the L-shaped clamping plate 2 to move forward and backward, so that the L-shaped clamping plate 2 pushes the automobile C-shaped beam to slide forward and gradually moves the automobile C-shaped beam to a horizontal state. After that, the adjusting screw 22 is rotated to drive the pressing plate 21 to move downward, so that the pressing plate 21 is squeezed and fixed on the top of the automobile C-shaped beam, thereby improving the stability of the automobile C-shaped beam.

[0030] like Figure 4 As shown, the second fixing mechanism includes a movable seat 3 and a slider 4. The movable seat 3 is arranged below the processing table 1. A second hydraulic cylinder 31 is installed at the bottom of the processing table 1 and in front of the movable seat 3. The top of the movable seat 3 is provided with a second slide groove 32 distributed in an array.

[0031] A plurality of sliders 4 are evenly distributed in an array and are slidably arranged on the inner side of the first slide groove 11. A clamping block 41 is welded and fixed on the top of the slider 4. The clamping block 41 cooperates with the L-shaped clamping plate 2 and the pressure plate 21 to fix the C-beam of the automobile. The upper surface of the clamping block 41 is lower than the lower surface of the movable frame 6, so as to avoid friction between the movable frame 6 and the clamping block 41. The bottom end of the slider 4 is slidably connected to the second slide groove 32. A push plate 42 is arranged at the bottom of the slider 4 and located on the inner side of the movable seat 3. A first spring 43 connected to the inner wall of the movable seat 3 is arranged on the front side of the push plate 42. Under the elastic action of the first spring 43, different clamping blocks 41 can contact the side wall surface of the automobile C-beam, so as to facilitate fixing according to the shape of the automobile C-beam.

[0032] When the second hydraulic cylinder 31 is running, it can push the movable seat 3 to move forward and backward, so that the movable seat 3 drives the slider 4 to move, so that the slider 4 slides along the first slide groove 11, and drives the clamping block 41 to approach the C-beam of the automobile. When the clamping block 41 contacts the C-beam of the automobile, the first spring 43 is deformed under the action of pressure and exerts pressure on the push plate 42 to ensure that different clamping blocks 41 are in close contact with the side wall of the C-beam of the automobile, thereby improving the fixing effect of the C-beam of the automobile.

[0033] like Figure 5 and Figure 6 As shown, a threaded rod 52 penetrating the slide 51 is provided on the inner side of the guide frame 5, and the threaded rod 52 is threadedly connected to the slide 51. A first motor 53 coaxially driven with the threaded rod 52 is installed on the left side of the guide frame 5. When the first motor 53 is running, the threaded rod 52 and the slide 51 move relative to each other, so that the slide 51 can drive the grinding mechanism to move left and right, and then the grinding mechanism can move along the curved surface of the automobile C-beam for grinding.

[0034] The top of the grinding wheel 61 is rotatably connected to the movable frame 6 through a rotating shaft. A second motor 63 for driving the grinding wheel 61 is installed on the top of the movable frame 6. The operation of the second motor 63 can drive the grinding wheel 61 to grind the corners of the automobile C-beam. The adjusting wheel 62 is arranged below the grinding wheel 61 and contacts the side wall surface of the C-beam. A movable rod 64 slidably connected to the slide seat 51 is provided on the front side of the movable frame 6 and near the top.

[0035] The adjusting rod 7 is arranged below the movable rod 64, the sleeve 71 is sleeved on the outside of the adjusting rod 7 and fixedly connected to the slide seat 51, a piston 72 is installed at the end of the adjusting rod 7 and on the inner side of the sleeve 71, and a second spring 73 is arranged between the piston 72 and the inner wall of the sleeve 71.

[0036] When the slide 51 drives the grinding mechanism to move left and right, the adjusting wheel 62 rolls along the surface of the automobile C-beam and causes the second spring 73 to deform. Under the action of the second spring 73 and the piston 72, the adjusting rod 7 can apply pressure to the movable frame 6, so that the surface of the grinding wheel 61 is always in contact with the automobile C-beam. At the same time, the grinding wheel 61 can be ground along the edge of the automobile C-beam.

[0037] A vent hole 74 is provided at the top of the sleeve 71 near the front edge. When the piston 72 slides in the sleeve 71 and activates the second spring 73, the gas inside the sleeve 71 can be discharged through the vent hole 74 to prevent the gas inside the sleeve 71 from being compressed and affecting the adjustment effect.

[0038] Working principle: First, place the automobile C-beam above the first slide groove 11, and make the first hydraulic cylinder 23 push the L-shaped clamping plate 2 to move forward, so that the L-shaped clamping plate 2 pushes the automobile C-beam forward to a horizontal state, then, rotate the adjusting screw 22 to drive the pressing plate 21 to move downward, and squeeze the automobile C-beam, then, operate the second hydraulic cylinder 31 to push the movable seat 3 to move, so that the movable seat 3 drives the slider 4 to slide along the first slide groove 11, and make the clamping block 41 close to the automobile C-beam, under the elastic action of the first spring 43, the clamping block 41 cooperates with the L-shaped clamping plate 2 and the pressing plate 21 to position and fix the automobile C-beam;

[0039] Furthermore, the second motor 63 is operated to drive the grinding wheel 61 to grind the corners of the automobile C-beam. After that, the first motor 53 is operated to drive the threaded rod 52 to rotate, so that the slide 51 drives the grinding mechanism to move left and right. During the movement, the second spring 73 and the piston 72 cooperate with each other to make the adjusting rod 7 apply pressure to the movable frame 6, so that the surface of the grinding wheel 61 is always in contact with the automobile C-beam, and the grinding wheel 61 is adaptively adjusted to grind along the edge of the automobile C-beam.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
