Description

Technical Field

[0001] This utility model relates to the field of automotive B-pillar lower guard plate processing technology, specifically a drilling device for processing automotive B-pillar lower guard plates. Background Technology

[0002] A B-pillar underbody protector is a protective device installed at the bottom of the B-pillar on the side of a vehicle. It protects the structure below the B-pillar and prevents damage from impacts to the vehicle body. It is typically made of plastic or other durable materials and offers scratch and abrasion protection. The design and shape of the B-pillar underbody protector vary depending on the vehicle model, and the drilling locations will also differ accordingly.

[0003] A drilling device for processing automotive B-pillar lower guard plates, authorized by announcement number CN220241652U, includes a bracket, a worktable fixedly mounted on the bracket, and a drilling table fixedly mounted on the worktable. The B-pillar lower guard plate is placed on the worktable. A mounting plate and a first electric telescopic rod are fixedly mounted on both sides of the top surface of the worktable, respectively. A left fixing mold is fixedly mounted on the output end of the first electric telescopic rod, and a right fixing mold is fixedly mounted on the mounting plate near the first electric telescopic rod. The left and right fixing molds are in contact with the B-pillar lower guard plate. A slag discharge groove penetrating the worktable is provided at the position corresponding to the position between the mounting plate and the first electric telescopic rod. This technical solution solves the problems of insufficient sturdiness in fixing automotive B-pillar lower guard plates and the slow pace of replacing them in existing technologies.

[0025] See Figures 1-5 This utility model provides the following two technical solutions:

[0026] First embodiment: A drilling device for processing the lower B-pillar guard plate of an automobile, including a processing box 1, and further comprising:

[0027] The auxiliary clamping mechanism 5 is located inside the processing box 1 and is used in conjunction with the fixed mold 9 to clamp the lower guard plate of the car B-pillar;

[0028] Dust extraction component 4 is installed on the outer wall of processing box 1 and is used to extract dust from inside processing box 1.

[0029] The bottom of the processing box 1 is fixedly equipped with a support leg 2 for the overall stability of the equipment. The inner wall of the processing box 1 is fixedly equipped with a drilling device body 7 for drilling the lower guard plate of the car B-pillar.

[0030] The inner wall of the processing box 1 is provided with a ramp groove 3 for the waste generated during the drilling of the B-pillar underbody protection plate of the car to fall down. The outer wall of the processing box 1 is provided with a sliding groove, and a collection box 6 is slidably connected to the outer wall of the sliding groove for collecting the waste generated during the drilling of the B-pillar underbody protection plate of the car.

[0031] The outer wall of the processing box 1 is fixedly equipped with a ramp plate 8, which is used to transport the waste chips generated during the drilling of the B-pillar lower guard plate of the car. The processing box 1 is connected to a fixed mold 9 through an auxiliary clamping mechanism 5, which is used to clamp the B-pillar lower guard plate of the car in conjunction with the auxiliary clamping mechanism 5.

[0032] The auxiliary clamping mechanism 5 includes a mounting box 51, which is fixedly mounted on the outer wall of the processing box 1. A gear 59 is fixedly connected inside the mounting box 51. A toothed plate 510 meshes with the outer wall of the gear 59. A movable plate 52 is fixedly connected to one end of the toothed plate 510. A hinge seat 53 is fixedly connected to the outer wall of the movable plate 52. A crank rocker arm 54 is hinged to the outer wall of the hinge seat 53. A limiting hinge platform 56 is hinged to the outer wall of the crank rocker arm 54. The limiting hinge platform 56 is fixedly mounted on the outer wall of the mounting box 51. A sliding sleeve 57 is fixedly connected to the inner wall of the limiting hinge platform 56. A hinge push rod 55 is hinged to the other end of the crank rocker arm 54. The hinge push rod 55 is slidably connected to the inner wall of the sliding sleeve 57. A fixed connection assembly 58 is provided at the other end of the hinge push rod 55.

[0033] The fixed connection assembly 58 includes an insertion seat 581, which is fixedly installed on one end of the hinged push rod 55. A connecting block 582 is fixedly installed on the top end of the insertion seat 581. A rotating plate 583 is rotatably installed on the outer wall of the connecting block 582. A threaded rod 584 is fixedly connected to one end of the rotating plate 583. A limit plate 586 is fixedly installed on one end of the threaded rod 584. A fixed seat 585 is threadedly connected to the outer wall of the threaded rod 584. A fixed clamping plate 587 is fixedly installed on the top end of the fixed seat 585.

[0034] The drilling device for processing the lower B-pillar guard plate of automobiles is equipped with an auxiliary clamping mechanism 5. The auxiliary clamping mechanism 5, in conjunction with the fixed mold 9, can effectively fix the lower B-pillar guard plate of automobiles, avoiding the displacement of the drilling position caused by the loosening of the workpiece during the drilling process, thereby improving the drilling accuracy and quality. Through the fixed connecting component 58 and the auxiliary clamping mechanism 5, the mold disassembly and assembly process is more convenient. At the same time, the fixed connecting component 58 can ensure that the mold can quickly reach the accurate working position after replacement, reducing the time for debugging and adjustment.

[0035] The main difference between the second implementation method and the first implementation method is that:

[0036] The dust extraction assembly 4 includes a connecting frame 41, which is fixed to the outer wall of the processing box 1 by bolts. A dust extraction box 42 is fixedly installed on the outer wall of the connecting frame 41. An inspection door 47 is hinged to the outer wall of the dust extraction box 42 for internal maintenance. A filter plate 44 is provided on the outer wall of the inspection door 47 for filtering dust and impurities in the air. A drive assembly B43 is fixedly installed at the top of the dust extraction box 42 for providing kinetic energy to the dust extraction fan 46. The output end of the drive assembly B43 is fixedly connected to the dust extraction fan 46 for exhausting dust. A dust extraction pipe 45 is fixedly connected to the outer wall of the dust extraction box 42.

[0037] The drilling device for processing the B-pillar lower guard plate of the car is equipped with a dust extraction component 4. During the drilling process, the dust extraction mechanism can promptly remove the generated debris and dust, preventing them from adhering to the surface of the guard plate or entering the processing equipment, thereby making the surface of the guard plate smoother and flatter, improving the processing quality. At the same time, the dust extraction mechanism can reduce the impact of dust on processing tools and equipment, such as preventing dust from entering the cutting edge of the drill bit, extending the service life of the tools, and also ensuring the accuracy and stability of the processing dimensions.

[0038] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0039] When using the equipment, first place the car's B-pillar underbody protection plate into the inner wall of the fixed mold 9, and then...

[0040] The servo motor at one end of the mounting box 51 is activated, driving the gear 59 connected to its output end. The gear 59 moves the gear plate 510 meshing with its outer wall, which in turn moves the movable plate 52 connected to one end. The movable plate 52 moves the hinge seat 53 fixedly connected to one end, which in turn moves the crank rocker arm 54 hinged to the other end. The crank rocker arm 54 rotates, causing the hinge push rod 55 hinged to the other end to slide in the sliding sleeve 57 within the limiting hinge platform 56. The sliding of the hinge push rod 55 moves the fixed connection assembly 58 at one end, which in turn moves the fixed mold 9 connected to one end and the B-pillar lower guard plate placed on its inner wall. The inward movement of the two fixed molds 9 securely clamps the B-pillar lower guard plate. Then, the drilling device is activated. 7. Drilling can be performed on the lower B-pillar of the car. When drilling generates dust, the drive assembly B43 can be activated to drive the dust extraction fan 46 to operate. The dust-laden air is then sent into the dust extraction box 42 through the dust extraction pipe 45. After being filtered by the air filter plate 44, the dust and impurities in the air can be trapped in the dust extraction box 42, while the clean air is discharged. After a period of retention, the inspection door 47 can be opened to clean the dust and impurities in the dust extraction box 42. When it is necessary to replace the fixed mold 9, the rotating plate 583 is rotated to drive the threaded rod 584 to rotate. As the threaded rod 584 rotates and is limited by the limiting groove, the fixed seat 585 and the fixed clamping plate 587 can be moved laterally. The fixed seat 585 gradually moves away from the fixed mold 9 at both ends, and the fixed clamping plate 587 gradually loosens the fixed mold 9. When it is loosened to a certain extent, the fixed mold 9 can be removed for replacement.
