Problems solved by technology

[0002] Car interior panels will be made into various types according to the requirements of the car shape, basically they will not be flat panels, some are sunken in the middle, and some have inclined edges, and the installation of interior panels requires installation holes , Some positions that do not match the size need to be trimmed before installation, but due to the shape limitation, the processing is not very convenient. The traditional manual trimming and drilling methods are not only low in accuracy, but also waste time and low work efficiency
[0003] Patent No. CN2017100196256 discloses a punching device for an automobile interior panel. The edge of the automobile interior panel is inclined on the body of the interior panel. The workbench on the workbench and several positioning mechanisms, punching mechanisms and punching drive mechanisms are arranged on the workbench. The upper part of the positioning mechanism is provided with an inclined space for accommodating the edge of the automobile interior trim panel. The arrangement of several positioning mechanisms is consistent with the The contour of the body of the automotive interior panel is adapted. The punching device proposed in this patent is only suitable for interior parts with inclined edges and the installation holes are located on the inclined surface. However, there are still many special-shaped automotive interior parts with mounting holes not on the inclined surface. For interior parts, this fixture cannot fully adapt to the processing requirements of other non-plate interior parts. This device only snaps the edge of the car interior panel into the positioning mechanism, and the interior parts are made of non-metal and have a soft texture. Deviating when snapping in will cause the inclined surface of the interior panel to bend excessively or even break. This invention proposes a processing fixture with moderate clamping force and wide application range.

Embodiment 1

[0027] Select a certain number of clamping units 6 according to the outer contour of the interior trim, so that they are distributed along the outer contour, insert the fixing screw 4 of the clamping unit 6 into the fixing hole 5, and tighten and fix the bottom with the locking bolt 3, for For interior parts with a large area, select a certain number of support units 7 at the lower end of the middle part of the interior part, insert the fixing screw 4 of the support unit 7 into the fixing hole 5, and tighten the bottom with the locking bolt 3 to fix the interior part. Place it on the upper end of the support device 1 63, turn the hollow screw 9 of the clamping device 62 to make it rotate upwards, move the hollow screw 9 to the upper position first, and start the cylinder 65 to extend the clamping device 62 downward until the piston When the rod reaches the longest position, turn the four hollow screw rods 9 on the clamping device 62, so that the hollow screw rods 9 on the clamp...

Embodiment 2

[0029] Such as Figure 4 As shown, there are four clamping units 6 and two supporting units 7. This combination method is used when processing rectangular interior parts. For example, when drilling the inner roof of a car, the four sides of the inner roof of the car have a certain inclination angle. , the four vertices of the inner roof of the car are respectively placed between the support device one 63 and the clamping device 62, and the middle part of the inner roof of the car is supported by the support unit 7, so that the inner roof of the car will not sag like the bottom when the punching operation is carried out.

Embodiment 3

[0031] Such as Figure 5 As shown, there are three clamping units 6 and one supporting unit 7. This combination method is used when processing the interior trim of the triangle shape. For example, when processing the interior trim panel of the left front door of the car, the three Two corners are respectively put into the supporting device one 63, and the control cylinder 65 clamps the left front door trim panel with the clamping device 62, and the center of the left front door trim panel is supported by the support unit 7, so that the middle part will not be affected by the process when it is processed. The force bends the deformation downward.

[0032]Based on the above, the clamping unit 6 and the supporting unit 7 of the present invention can be used in any number of combinations, suitable for interior components of different sizes and shapes, and the scope of application is wider than that of special clamps. Reduce the design and production cost of special fixtures, and ...

Abstract

The invention discloses a machining clamp of an automobile interior trim part. The machining clamp comprises a workbench, supporting feet are arranged at the lower end of the workbench, and a plurality of clamping units and a plurality of supporting units are arranged on the workbench; the clamping units comprise C-shaped supports, vertical plates I are arranged at the lower ends of the inner sides of the supports, supporting devices I are fixed at the tops of the vertical plates I, air cylinders are fixed at the upper ends of the supports, clamping devices are fixed at the front ends of piston rods of the air cylinders, and the clamping devices and the supporting devices are symmetrical up and down relative to the horizontal line; and the supporting units comprise bottom plates, verticalplates II are arranged at the upper ends of the bottom plates, and supporting devices II are fixed to the tops of the vertical plates II. The machining clamp of the automobile interior trim part is suitable for the interior trim parts of different sizes and shapes, the application range is wider than that of a special clamp, and the design and manufacturing cost of the special clamp is reduced; inthe case of a pressing part of the interior trim part, the traditional single-point pressing is changed into pressing through four pressing rods, clamping is safer and more stable; and the four pressing rods can be freely adjusted to adapt to non-planar clamping of the interior trim part.
