Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing equipment technology, and in particular to a positioning table for processing automotive interior parts. Background Technology

[0002] Automotive interior parts, such as dashboards, door panels, and center armrests, require precise machining and positioning during the manufacturing process. To ensure machining accuracy and subsequent assembly quality, positioning tables and special fixtures must be used to reliably fix the interior parts to prevent displacement during machining.

[0003] However, automotive interior parts differ from traditional mechanical parts. They have large dimensions, irregular streamlined curved shapes, and complex and varied edge contours. More importantly, their surfaces are covered with leather textures, soft coatings, fabrics, and electroplating layers. These surfaces can be scratched and permanently indented by rigid objects during clamping, resulting in poor product appearance and a decrease in yield.

[0004] In order to achieve clamping stability, existing positioning tables use rigid clamping blocks and straight pressure plates, and apply clamping force in one direction through cylinders and bolts. When this rigid structure is used to position interior parts with complex curved edges, the contact surface of the fixture is difficult to achieve an ideal fit with the irregular contour of the workpiece, often resulting in a small contact area and stress concentration.

[0005] The mismatch between this structure and the characteristics of the workpiece leads to the core defect of the existing technology: In order to ensure stable positioning, the clamping force is increased, and the rigid clamping block will cause scratches and indentations on the precision surface of the workpiece. Conversely, if the clamping force is reduced in order to protect the surface, it is impossible to achieve effective fit and stable fixation of irregular edges. The workpiece will loosen during processing vibration, which will seriously affect the processing quality. Therefore, the existing technology is difficult to meet the dual requirements of stable fixation and surface protection of automotive interior parts at the same time.

[0006] Therefore, this utility model proposes a positioning table for processing automotive interior parts to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems existing in the positioning stage for processing automotive interior parts, such as difficulty in achieving stable fit when clamping automotive interior parts with complex curved edges, and the problem that rigid clamps can cause scratches and pressure marks on the precision surface of the workpiece, this utility model aims to provide a positioning stage for processing automotive interior parts with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a positioning table for processing automotive interior parts, comprising: a processing table; a limiting frame fixedly connected to the top of the processing table; a cylinder one fixedly connected to the limiting frame inside; a guide column passing through the limiting frame; a push plate fixedly connected to the output end of the cylinder one, the push plate slidingly engaging with the guide column; a cylinder two installed on the top rear side of the processing table; a sliding column fixedly connected to the top of the processing table; a pin fixedly connected to the top rear side of the processing table; a swing arm rotatably connected to the pin; a rotating plate fixedly connected to one side of the push plate; a large positioning block rotatably connected to the rotating plate; a small positioning block rotatably connected to the large positioning block; a roller rotatably connected to the outer wall of the small positioning block; a connecting piece fixedly connected to the output end of the cylinder two, the bottom of the connecting piece slidably connected to the top of the sliding column; a rotating column slidably connected to the front end of the connecting piece, the rotating column passing through the bottom of the swing arm; and a rubber pad fixedly connected to the top front side of the swing arm.

[0009] Preferably, the limiting frame is set on the top left and right sides of the processing table to form a symmetrical layout; and the cylinder, guide column, push plate and rotating plate are arranged symmetrically accordingly. This structure makes the lateral clamping force more balanced and improves the stability of positioning.

[0010] Preferably, the guide posts are located at the front and rear ends of the left side of the limiting frame. The push plate is guided and slid through the cooperation of the guide posts. This front and rear guide post structure can effectively resist the deflection torque generated by the push plate during movement, ensuring the stability of linear motion.

[0011] Preferably, the small positioning blocks are rotatably connected to the top front and rear sides of the large positioning block. This multi-point arrangement of small positioning blocks can further enhance the ability to conform to the small irregular parts of the workpiece edges and grooves, and improve the range of fine positioning.

[0012] Preferably, the outer wall of the small positioning block is rotatably connected with a plurality of rollers. The arrangement of the plurality of rollers increases the contact area with the workpiece, and rolling friction replaces sliding friction. While reducing frictional resistance, it also protects the workpiece surface from scratches to the greatest extent.

[0013] Preferably, the output end of cylinder two is fixedly connected to the rear side of the connector. This connection method clarifies the power transmission path of the top clamping mechanism, has a clear structure, and is easy to install and maintain.

[0014] Preferably, the pin is fixed to the left and right ends of the top rear side of the processing table, and the swing arms are arranged symmetrically accordingly, so that the top clamping force can be evenly distributed on the workpiece, avoiding uneven force on one side that causes the workpiece to warp and deform.

[0015] Preferably, the rotating column is slidably connected to the left and right front ends of the connector. This sliding connection design is to compensate for the displacement difference between the swing arm and the linear motion of the connector when the swing arm makes an arc motion around the pin shaft, to prevent the mechanism from jamming and to ensure smooth movement.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem that rigid clamps in the prior art are difficult to fit the complex and irregular curved edges of automotive interior parts by setting up a multi-stage rotational contouring mechanism driven by a push plate and including a rotating plate, a large positioning block and a small positioning block. It achieves the effect that the positioning device can adapt to the workpiece contour, has a high degree of clamping fit and strong versatility.

[0017] 2. This utility model solves the problem that rigid clamps in the prior art will cause scratches and pressure damage to the surface of interior parts during positioning by setting rollers at the end of the lateral contouring mechanism for rolling contact and setting rubber pads on the top pressing swing arm for flexible contact, thereby effectively protecting the surface quality of the workpiece and avoiding the production of defective products.

[0018] 3. This utility model solves the problems of complex structure and occupation of space above the workpiece when the clamping mechanism is released by setting a connecting rod clamping mechanism driven by a cylinder and then pushing the swing arm to swing around the pin shaft. It achieves the effect of converting the linear motion of the cylinder into swing arm clamping, simplifying the structure, and in the non-working state, the clamping component can completely avoid the material picking and placing path above the workpiece, thus improving the efficiency of loading and unloading.

[0022] Example: Please refer to Figures 1 to 4 This utility model provides a positioning stage for processing automotive interior parts, which aims to solve the problems in the prior art where it is difficult to effectively fit the complex and varied curved edges of the interior parts when clamping them, and rigid clamping can cause scratches and pressure marks on the workpiece surface.

[0023] like Figure 1 As shown, a positioning table for processing automotive interior parts includes a processing table 1, with a limit frame 2 fixedly connected to the top of the processing table 1; like Figure 2 As shown, a cylinder 4 is fixedly connected inside the limiting frame 2, and a guide post 3 passes through the limiting frame 2; a push plate 5 is fixedly connected to the output end of the cylinder 4, and the push plate 5 is slidably fitted to the guide post 3; as shown Figure 1 As shown, a cylinder 10 is mounted on the top rear side of the machining table 1; a sliding column 16 is fixedly connected to the top of the machining table 1; and a pin 12 is fixedly connected to the top rear side of the machining table 1, as shown. Figure 4 As shown, the pivot pin 12 is rotatably connected to the swing arm 14.

[0024] Please refer to Figure 2 A rotating plate 6 is fixedly connected to one side of the push plate 5. A large positioning block 7 is rotatably connected to the rotating plate 6. A small positioning block 8 is rotatably connected to the large positioning block 7. A roller 9 is rotatably connected to the outer wall of the small positioning block 8. This multi-stage rotation structure ensures that when the cylinder 4 drives the push plate 5 to move, the roller 9 can contact the workpiece first, and the large positioning block 7 and the small positioning block 8 rotate accordingly to fit the irregular side contour of the workpiece. Please refer to Figure 3 and Figure 4 The output end of cylinder 10 is fixedly connected to a connector 11. The bottom of connector 11 is slidably connected to the top of slide column 16. Slide column 16 provides guidance for the linear movement of connector 11. The front end of connector 11 is slidably connected to a rotating column 13, which passes through the bottom of swing arm 14. A rubber pad 15 is fixedly connected to the top front side of swing arm 14. This linkage structure ensures that when cylinder 10 pushes connector 11 to move, it can drive swing arm 14 to swing around pin 12, ultimately causing rubber pad 15 to press down and fix the workpiece.

[0025] In a preferred embodiment, in order to improve the stability of clamping, the limiting frame 2 is set on the top left and right sides of the processing table 1, and the cylinder 4, guide column 3, push plate 5 and rotating plate 6 are arranged symmetrically accordingly. As another preferred embodiment, in order to ensure the stability of the sliding of the push plate 5, the guide post 3 is set at the front and rear ends of the left side of the limiting frame 2, and the push plate 5 is guided to slide through the guide post 3; As another preferred embodiment, in order to enhance the precision of contour positioning, the small positioning block 8 is rotatably connected to the top front and rear sides of the large positioning block 7. As another preferred embodiment, in order to reduce contact friction, a plurality of rollers 9 are rotatably connected to the outer wall of the small positioning block 8; As another preferred embodiment, in order to clarify the power transmission path, the output end of cylinder 2 10 is fixedly connected to the rear side of connector 11. In another preferred embodiment, in order to make the top clamping force uniform, the pin 12 is fixed to the left and right ends of the top rear side of the processing table 1, and the swing arms 14 are arranged symmetrically accordingly. In another preferred embodiment, in order to achieve motion conversion, the rotating column 13 is slidably connected to the left and right front ends of the connector 11.

[0026] Working principle: Place the interior parts on top of the processing table 1; When cylinder 4 is activated, its output end drives push plate 5 to move. Push plate 5 slides along guide post 3 and engages with guide post 3. Push plate 5 drives rotating plate 6, which in turn pushes large positioning block 7. Large positioning block 7 pushes small positioning block 8 until roller 9 contacts the surface of interior trim. Due to the continuous thrust of cylinder 4, large positioning block 7 and small positioning block 8 will rotate and fit according to the shape of interior trim, completing lateral positioning. At the same time, cylinder 2 10 starts and pushes the connecting piece 11 forward. The bottom of the connecting piece 11 is slidably connected to the top of the sliding column 16, and the sliding column 16 guides the movement of the connecting piece 11. The connecting piece 11 pushes the bottom of the swing arm 14 through the rotating column 13. Since the swing arm 14 is rotatably connected to the pin 12, the linear motion of the connecting piece 11 is converted into the swing of the swing arm 14. Finally, the rubber pad 15 on the top front side of the swing arm 14 presses down and clamps the interior trim to achieve the positioning function.
