DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0025] Reference Figure 1 As shown, an engine hood processing fixture of the utility model comprises a base 1;

[0026] Two support plates 2 are fixedly mounted on the upper end of the base 1, and a clamping mechanism 3 is mounted on the upper end of the two support plates 2;

[0027] The driving mechanism 4 is used to control the clamping and loosening of the clamping mechanism 3;

[0028] A sliding mechanism 5, used for adjusting the distance between the two support plates 2;

[0029] A guard frame 31 is fixedly installed on the upper end of the support plate 2, a groove 32 is opened on one side of the guard frame 31, two fixing plates 33 are fixedly installed on the inner surface of the guard frame 31, a slide bar 34 penetrating both sides of the guard frame 31 is fixedly installed between the two fixing plates 33, and springs 35 are wound and installed at both ends of the slide bar 34 near the opposite sides of the two fixing plates 33;

[0030] Two movable rods 381 are slidably installed on the inner surface of the protective frame 31, and springs 382 are wound and installed on the outer surfaces of the two movable rods 381. A concave connecting plate 383 is fixedly installed on the opposite surfaces of the two movable rods 381. A rotating shaft 384 is fixedly installed in the middle of the concave connecting plate 383. The outer surface of the rotating shaft 384 is rotatably connected to two clamping arms 36. A sliding groove 361 is opened in the middle of the two clamping arms 36. The inner surfaces of the two sliding grooves 361 are slidably connected to the outer surface of the sliding rod 34. The inner surface of the groove 32 is slidably connected to the driving mechanism 4, and the inner surface of the base 1 is fixedly connected to the sliding mechanism 5.

[0031] During operation, the engine hood cover is first placed on the two support plates 2, and the driving mechanism 4 drives the two clamping arms 36 to clamp the engine hood cover. The driving mechanism 4 pushes open the two clamping arms 36, and the slide bar 34 slides on the inner surfaces of the two slide grooves 361. During the sliding process, the clamping arms 36 squeeze the springs 35 on both sides. Due to the action of the rotating shaft 384, the other end of the clamping arms 36 will be clamped. During the clamping process, the concave connecting plate 383 is slidably connected to the support plate 2, and the two movable rods 381 are also slidably installed on both sides of the guard frame 31. During the clamping process of the engine hood cover, During the process, relative sliding occurs between the movable rod 381 and the guard frame 31, and a concave connecting plate 383 is fixedly connected between the opposite surfaces of the two movable rods 381. During the clamping process of the engine hood cover, the concave connecting plate 383 will deflect along with the position of the engine hood cover, which can effectively prevent the engine hood cover from being torn due to the inability to move due to the clamp being too tight, thereby affecting the processing and use. Due to the action of spring 2 382, ​​after the engine hood cover is taken out, the concave connecting plate 383 will return to its initial position, waiting for the next engine hood cover to be clamped and fixed for processing.

[0032] Reference Figure 3 As shown, in one embodiment of the present invention, a rotating wheel 37 is rotatably mounted on one end of the two clamping arms 36 , and clamping teeth 39 are fixedly mounted between opposite surfaces of the other ends of the two clamping arms 36 .

[0033] During operation, the clamping teeth 39 on the opposite surfaces of the two clamping arms 36 can make the clamping arms 36 clamp the engine cover more firmly, and can prevent the device from falling off after clamping the engine cover.

[0034] Reference Figure 4 As shown, in one embodiment of the utility model, the driving mechanism 4 includes a cylinder 41, the cylinder 41 is fixedly installed on one side of the support plate 2, the piston rod of the cylinder 41 is fixedly connected to a connecting rod 42, the other end of the connecting rod 42 is fixedly connected to a special-shaped plate 43, the special-shaped plate 43 is slidably installed on the inner surface of the groove three 32, and the outer surface of the special-shaped plate 43 is rotatably connected to the outer surfaces of the two rotating wheels 37.

[0035] During operation, the cylinder 41 can drive the connecting rod 42 to move. When the engine hood needs to be clamped, the cylinder 41 retracts the piston rod, and the two side surfaces of the special-shaped plate 43 rotate and rub against the outer surfaces of the two rotating wheels 37. Since the special-shaped plate 43 is narrow at one end and wide at the other end, when the piston rod of the cylinder 41 drives the special-shaped plate 43, the special-shaped plate 43 can control the two rotating wheels 37 to move away from each other, and one end of the clamping arm 36 equipped with the rotating wheel 37 will also move away from each other, and the other end of the clamping arm 36 can clamp the engine hood. When the engine hood needs to be released, the piston rod is extended by the cylinder 41, and the special-shaped plate 43 moves away from the two rotating wheels 37, and the two ends of the clamping arm 36 close to the rotating wheel 37 move closer to each other under the action of the spring 1 35.

[0036] Reference Figure 5 As shown, in one embodiment of the utility model, a groove 11 is provided in the middle of the base 1, a groove 2 12 is provided on one side of the base 1, and the sliding mechanism 5 includes a motor 51, and the motor 51 is fixedly installed on the inner surface of the groove 2 12, and a pulley 52 is fixedly connected to the transmission shaft at the output end of the motor 51, and a belt 53 is wound around the outer surface of the pulley 52, and a bidirectional threaded rod 54 is wound around the other end of the belt 53, and the bidirectional threaded rod 54 is rotatably installed on the inner surface of the groove 2 12, and sliders 55 are respectively threadedly connected at both ends of the bidirectional threaded rod 54, and the upper parts of the two sliders 55 are fixedly connected to the support plate 2, and the two sliders 55 are slidably installed on the inner surface of the groove 11.

[0037] When working, the transmission shaft at the output end of the motor 51 is connected to the pulley 52, and the pulley 52 and the bidirectional threaded rod 54 are connected together by the belt 53. When the motor 51 drives the pulley 52 to rotate, the belt 53 drives the bidirectional threaded rod 54 to rotate, and the two sliders 55 move toward each other under the action of the bidirectional threaded rod 54, and the upper ends of the two sliders 55 are respectively connected to the support plates 2. Therefore, the device can control the relative distance between the two support plates 2 and the two clamps by adjusting the relative positions of the two sliders 55. This structure is driven by the motor 51, which can not only achieve precise control, but also save the effort of the staff.

[0038] Working principle: First, the distance between the two support plates 2 and the two clamps is controlled by the motor 51, and the engine hood cover is placed on the two support plates 2. At this time, the cylinder 41 is started, and the position of the special-shaped plate 43 is controlled by the connecting rod 42. When the special-shaped plate 43 passes through the two rotating wheels 37, one end of the two clamping arms 36 moves away from each other, and the other end approaches each other. In the process of clamping the engine hood cover when one end of the clamping arms 36 approaches each other, due to the position of the engine hood cover, the concave connecting plate 383 will be deflected, and the two movable rods 381 and the guard frame 31 will slide relative to each other. Under the action of the clamping teeth 39, the clamping arms 36 clamp the engine hood cover.

[0039] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention of the utility model.
