Description

Technical Field

[0001] This utility model relates to the field of chassis manufacturing technology, specifically to a grinding device for chassis manufacturing. Background Technology

[0002] Grinding equipment used in chassis production is mainly used for surface treatment of metal or non-metal chassis shells to remove burrs, sharp edges, oxide layers or welding marks, and improve surface smoothness and appearance quality.

[0003] Currently, most existing equipment requires manual removal of the sheet metal from the machine, manual flipping, and reinstallation for the other side when performing double-sided sanding of chassis panels. This method is not only inefficient but also prone to causing secondary damage or misalignment to the sheet metal during the flipping process, resulting in inconsistent sanding precision on both sides and affecting the overall quality of the chassis. Therefore, we propose a sanding device for chassis production. Utility Model Content

[0012] This utility model provides a grinding device for chassis manufacturing. It has the following beneficial effects: (1) The grinding equipment for chassis production realizes automatic feeding and resetting of the plate through screw drive. With the differential structural design at both ends of the extrusion rod, the rack and gear are precisely driven to mesh during the resetting process, causing the plate to automatically rotate 180 degrees.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-6 This utility model proposes a grinding equipment for chassis production, including an operating table 1, a support 2 connected to the outer wall of the operating table 1, a moving mechanism 3 on the support 2, a grinding device 4 on the moving mechanism 3, a support plate 14 below the grinding device 4, the support plate 14 being connected to the outer wall of the operating table 1, a sliding groove 13 on the operating table 1, a side plate 11 connected to the outer wall of the operating table 1, a through groove 12 on the side plate 1, and a feeding mechanism on the operating table 1.

[0020] In the embodiments of this utility model, in order to achieve automatic feeding, the feeding mechanism specifically includes a moving block 52, which is slidably connected to the through groove 12. The moving block 52 is penetrated by a shaft 54 ​​and rotatably connected to the shaft 54. One end of the shaft 54 ​​is connected to a gear 541, and the other end is connected to a rotating plate 542. A moving block 53 is connected to the outer wall of the moving block 52. The moving block 53 is penetrated by a screw 51 and threadedly connected to the screw 51. A pressing rod 56 is connected to the outer wall of the moving block 53. Furthermore, the rotating plate 542 is penetrated by the threaded bolt 55 and threadedly connected to the threaded bolt 55. The end of the threaded bolt 55 is rotatably connected to the pressure plate 551. There are four sets of threaded bolts 55 and pressure plates 551, which are symmetrically distributed on the outer wall of the rotating plate 542 in the upper and lower and left and right directions. Furthermore, a gear 15 is slidably connected to the inner wall of the operating table 1, and a moving rod 151 is connected to the outer wall of the gear 15. The moving rod 151 passes through the base 152 and is slidably connected to the base 152. The base 152 is connected to the operating table 1 by bolts. A tension spring 153 is provided between the gear 15 and the base 152. The bottom end of the moving rod 151 is passed through by a rod body 154 and is slidably connected to the rod body 154. A spring 155 is provided between the outer wall of the rod body 154 and the moving rod 151. In this utility model, when in use, such as Figure 3 As shown, when clamping and fixing the sheet metal, first rotate the threaded bolt 55 at the bottom of the device in sequence. Through the threaded transmission, the lower pressure plate 551 moves upward in the vertical direction. When the lower pressure plate 551 rises to the predetermined position, stop rotating the threaded bolt 55 to complete the bottom support positioning. Then, place the sheet metal to be processed stably on the outer surface of the lower pressure plate 551. Through the positioning function of the pressure plate 551, ensure that the center of the sheet metal is aligned with the center of the rotating plate 542 to avoid the sheet metal from shifting during subsequent processing. After placement, turn the threaded bolt 55 at the top of the device. Similarly, through the threaded transmission, the upper pressure plate 551 moves downward until the upper and lower pressure plates 551 are tightly attached to the upper and lower surfaces of the sheet metal, thereby firmly clamping the sheet metal between the two pressure plates 551 and providing a stable fixing effect for subsequent rotation processing. Next, the motor is started, driving the screw 51 to rotate. Under the threaded transmission of the screw 51, the moving block 52 moves smoothly along the axial direction of the screw 51. After the moving block 52 moves the plate a certain distance, the end of the pressing rod 56 on its side wall will contact the rod body 154 and apply a pressing force to the rod body 154, forcing the rod body 154 to contract inward towards the moving rod 151. At the same time, the internal spring 155 is compressed and undergoes elastic deformation. When the moving block 52 moves the plate to directly above the support plate 14, the motor is turned off to stop the moving block 52 from moving. Then, the moving mechanism 3 and the grinding device 4 are started respectively: the moving mechanism 3 drives the grinding device 4 to adjust to a suitable grinding position and angle, and the grinding device 4 grinds the surface of the plate above the support plate 14. After grinding is complete, the motor is started in reverse, driving the screw 51 to rotate in the opposite direction. This causes the moving block 52 to move the plate, which has been ground on one side, back to its original position along the original path. During the resetting process, the inclined surface at the end of the pressing rod 56 will contact the rod body 154. The inclined surface structure will apply an upward force to the rod body 154, pushing it upward. This, in turn, will cause the moving rod 151 and the toothed rod 15 connected to it to rise synchronously. At the same time, the tension spring 153 connected to the bottom of the toothed rod 15 will be stretched and in an elastic deformation state.

[0021] When the moving block 52 continues to reset and move to a specific position, the rack 15 will mesh with the gear 541; at this time, the continuously rising rack 15 will apply a rotational force to the gear 541, causing the shaft 54 ​​to rotate, thereby causing the rotating plate 542 fixedly connected to the shaft 54 ​​and the clamped plate to rotate 180 degrees synchronously, realizing the flipping of the plate. After the flipping is completed, the motor is controlled to rotate forward again, driving the moving block 52 to move the plate back towards the grinding device 4, so that the un-grinded side of the plate faces the grinding mechanism. Then the moving mechanism 3 and the grinding device 4 can be started to grind the other side of the plate, ensuring that both sides of the plate meet the processing requirements. It should be noted that, for example Figure 6 As shown, the two ends of the extrusion rod 56 are designed differently: one end is an arc-shaped structure, and the other end is a beveled structure. This design, when combined with the rod body 154, enables precise unidirectional transmission control: when the moving block 52 moves towards the grinding device 4, i.e., when the plate is fed forward, the arc-shaped end of the extrusion rod 56 contacts the rod body 154. The arc-shaped structure slides smoothly along the surface of the rod body 154, generating only a lateral thrust that causes the rod body 154 to contract inward towards the moving rod 151, deforming the spring 155, without applying an upward force to the rod body 154. Therefore, the rack 15 remains stationary and does not mesh with the gear 541, ensuring that the rotating plate 542 and the plate do not rotate. When the moving block 52 resets and moves in the opposite direction, the beveled end of the extrusion rod 56 contacts the rod body 154. The inclined structure will generate an upward component force on the rod 154, pushing the rod 154, the moving rod 151 and the rack 15 to rise synchronously, so that the rack 15 and the gear 541 mesh precisely, thereby driving the rotating plate 542 to rotate.

[0022] This design achieves a unidirectional control effect by using the structural differences at both ends of the pressing rod 56. When the moving block 52 moves forward, the rack 15 remains stationary, and when it resets in the reverse direction, the rack 15 drives the gear 541 to rotate. This ensures that the rotating plate 542 only completes the flipping action during the plate reset process, avoiding accidental rotation during the grinding process.

[0023] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
