[0002] The cross beam of the car is formed by stamping, that is, the cross beam of the automobile frame is processed by stamping technology. The longitudinal beam and the cross beam are the basic parts of the automobile frame. The longitudinal beam is mostly in the form of channel steel, which is stamped by high-strength medium-thick steel plates. The cross beams are divided into trough beams, arched beams and II-shaped beams according to their different functions. The cross beams are mostly stamped by high-strength medium-thick steel plates. After stamping, the cross beam needs to be polished to remove the burrs on the surface of the cross beam and make the surface of the cross beam smoother. At present, the market mainly uses hook-type shot blasting machines for polishing and grinding.
[0003] However, the existing hook-type shot blasting machine mainly hangs the automobile beam on a disc, and then drives the entire disc to move through an electric slide, the gears on the outer wall of the moving disc are in contact with the toothed chain inside the shot blasting machine, and the toothed chain drives the gears and the disc to rotate to grind the automobile beam hung on the disc. However, in this rotation mode, the shot blasting machine can only fully grind the part of the automobile beam away from the center of the disc, while the part of the automobile beam close to the center of the disc is prone to grinding dead corners. Based on this, a grinding device for automobile beam processing that can fully grind the automobile beam is provided. Utility Model Content

[0025] The utility model provides a grinding device for processing automobile cross beams, such as Figure 1-5 As shown, it includes a grinding assembly 1 having a shot blasting machine housing 101, an electric slide 102 is installed on the top of the shot blasting machine housing 101, a first hook 103 is fixedly connected to the bottom wall of the slide seat of the electric slide 102, and a suspension assembly 2 is hung at the bottom of the first hook 103, and the suspension assembly 2 includes:
[0026] A rotating cylinder 201 is placed inside the shot blasting machine housing 101, and the outer wall of the rotating cylinder 201 is fixedly connected with a third gear 209, a first disc 202, and a second disc 203 in sequence from top to bottom. The first disc 202 and the second disc 203 are distributed inside the shot blasting machine housing 101, and the bottom wall of the first disc 202 is rotatably connected with a second hook 204;
[0027] A round rod 205 is rotatably connected inside the second disc 203, the upper end of the round rod 205 extends to the upper end of the second disc 203, the bottom end of the round rod 205 extends to the bottom wall of the second disc 203, and the outer wall of the round rod 205 is located at the bottom of the second disc 203 and fixedly connected to a first gear 206;
[0028] A fixing rod 207 is rotatably connected inside the rotating cylinder 201. The upper end of the fixing rod 207 extends to the top wall of the rotating cylinder 201 and is detachably connected to the first hook 103. The lower end of the fixing rod 207 extends to the bottom wall of the second disc 203 and is fixedly connected to a second gear 208. The second gear 208 is meshed with the first gear 206.
[0029] A slide groove is provided on the top of the shot blasting machine housing 101 for the rotating cylinder 201, the third gear 209 and the first hook 103 to move. The slide groove extends to one end of the outer side of the shot blasting machine housing 101. A toothed chain 104 is provided inside the slide groove at a position aligned with the third gear 209. The toothed chain 104 meshes with the third gear 209.
[0030] A connecting groove 2010 is formed at the upper end of the round rod 205, and external hooks of different lengths can be connected through the connecting groove 2010. The external hook and the second hook 204 are respectively used to connect the upper and lower holes of the automobile beam to fix the automobile beam.
[0031] In this embodiment, it should be particularly noted that: a driving assembly for driving the toothed chain 104 is disposed on the top of the shot blasting machine housing 101;
[0032] When the shot blasting machine is actually grinding the automobile beam, firstly, a matching external hook is selected according to the actual length of the automobile beam. After the external hook is connected to the connecting groove 2010 on the round rod 205, the distance between the top of the external hook and the bottom of the second hook 204 matches the length of the automobile beam to be ground.
[0033] When performing the automobile beam grinding operation, the electric slide 102 is first started to move the suspension assembly 2 as a whole to the outside of the shot blasting machine housing 101, and then the automobile beam to be ground is hung between the second hook 204 and the external hook. After all the automobile beams are hung, the electric slide 102 is started again, and the electric slide 102 drives the suspension assembly 2 to move to the inside of the shot blasting machine housing 101. During this process, the third gear 209 gradually contacts and meshes with the toothed chain 104;
[0034] After the suspension assembly 2 enters the shot blasting machine housing 101, the door of the shot blasting machine housing 101 is closed, and the driving assembly is started to operate the toothed chain 104. The toothed chain 104 drives the third gear 209 to rotate, and the rotating third gear 209 drives the first disc 202, the rotating cylinder 201, and the second disc 203 to rotate synchronously, and the round rod 205 and the first gear 206 perform circular motion synchronously. Since the first gear 206 is meshed with the second gear 208, and the second gear 208 and the fixed rod 207 cannot rotate under the limit of the first hook 103, the first gear 206 will rotate while performing the circular motion, and the rotating first gear 206 drives the external hook, the second hook 204 and the automobile beam to rotate synchronously. At this time, the purpose of the shot blasting machine being able to fully grind every corner of the automobile beam is achieved.
[0035] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the second hook 204, the round rod 205, and the first gear 206 are provided in multiple groups and are distributed in a circle on the outer wall of the rotating cylinder 201 and the second disc 203, and the second hook 204 and the round rod 205 are aligned in the vertical direction.
[0036] In this embodiment, the structure can realize the synchronous grinding operation of multiple automobile cross beams, and can better perform the grinding operation of batch automobile cross beams.
[0037] In a further preferred embodiment of the present invention, Figure 5 As shown, a thread groove is formed at the bottom of the second disk 203 outside the plurality of first gears 206 , and the second disk 203 is connected to a protective cover 3 via the thread groove. The protective cover 3 is used to protect the transmission space of the first gears 206 and 208 .
[0038] In this embodiment, the protective cover 3 can prevent the projectiles inside the shot blasting machine from contacting the first gear 206 and the second gear 208, causing wear of the first gear 206 and the second gear 208. The detachable structure of the protective cover 3 facilitates subsequent maintenance work (it should be noted that: Figure 1 The protective cover 3 is not installed in the middle. In actual use, the protective cover 3 is installed at the bottom of the second disc 203);
[0039] It is also necessary to explain that a dustproof strip is installed on the inner side of the top chute of the shot blasting machine housing 101 below the toothed chain 104 to prevent the projectiles from leaking out through the chute.
