Description

Technical Field

[0001] This utility model relates to the field of adsorption fixture technology, specifically an adsorption fixture for external viewing mirrors. Background Technology

[0002] In the production of automotive exterior mirrors, the cutting process is one of the key steps, requiring high-precision positioning and stable fixation of the workpiece. Since exterior mirror workpieces are mostly curved structures, and vibration and stress are generated during the cutting process, traditional fixtures are prone to problems such as unstable clamping and positioning deviations. This not only affects the cutting accuracy but may also cause workpiece displacement, creating safety hazards. At the same time, traditional mechanical clamping methods are also prone to leaving clamp marks or causing deformation on the workpiece surface.

[0003] To solve the above problems, there is an urgent need for an adsorption fixture specifically designed for cutting external sight glasses. This fixture should be able to achieve precise fit with the curved surface of the workpiece, provide sufficient adsorption force to resist external forces during the cutting process, and avoid damage to the workpiece surface. Utility Model Content

[0004] The purpose of this invention is to provide an external viewing mirror adsorption fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an external viewing mirror adsorption fixture, comprising an adsorption platform and several support blocks fixed at the top of the adsorption platform, wherein the curvature of the top of the support block is adapted to the curvature of the workpiece, an adsorption hole is provided on the support block, and a vacuum hole communicating with the adsorption hole is provided on the adsorption platform, wherein the vacuum hole is used to connect a negative pressure device to realize a vacuum operation.

[0006] Furthermore, the adsorption platform and the workpiece are designed to mimic each other.

[0007] Furthermore, a limiting baffle for limiting the workpiece is provided at the edge of the adsorption platform.

[0008] Furthermore, the limiting baffles are respectively fixed on two adjacent sides of the adsorption platform.

[0009] Furthermore, the adsorption platform is provided with several connecting channels that correspond one-to-one with the evacuation holes, and the connecting channels are connected to the evacuation holes. The connecting channels are used to connect several adsorption holes located on the same straight line.

[0010] Furthermore, all the adsorption pores are funnel-shaped, with the top being larger than the bottom.

[0011] Furthermore, several of the aforementioned support blocks are integrally formed with the adsorption platform.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) By matching the curvature of the top of the support block with the curvature of the workpiece, and with the negative pressure adsorption structure, the workpiece and the fixture are closely fitted, providing uniform and stable adsorption force during the cutting process, effectively resisting external cutting force, ensuring that the workpiece does not shift during the cutting process, and avoiding the incomplete cutting due to changes in the focal length caused by curvature issues.

[0013] (2) The limiting baffle set at the edge of the adsorption platform can preposition the workpiece before adsorption and fixation, ensuring the consistency of the workpiece placement position. At the same time, it helps resist the lateral force during the cutting process, preventing the workpiece from being horizontally displaced, thus improving the consistency of batch cutting.

[0014] (3) The design of the internal connection channel of the adsorption platform realizes the efficient distribution of negative pressure, so that the adsorption holes on the same straight line can obtain uniform adsorption force, avoid the local deformation of the workpiece caused by uneven adsorption force, and ensure the flatness of the cut surface.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Please see Figure 1-4 This utility model provides an embodiment of an external viewing mirror adsorption fixture, which includes an adsorption platform 1 and several support blocks 2 fixed to the top of the adsorption platform 1. In this embodiment, the adsorption platform 1 and the workpiece adopt a contour-following design, specifically a cuboid structure. The number of support blocks 2 is set to four, which are respectively set at the four corners of the adsorption platform 1. The support blocks 2 and the adsorption platform 1 are integrally formed, which improves the overall structural strength and rigidity of the fixture, enhances the vibration resistance, can withstand high-frequency vibration during the cutting process, extends the service life of the fixture, and reduces the processing error caused by fixture deformation.

[0019] The support block 2 has an adsorption hole 201, and the adsorption platform 1 has a vacuum hole 3 that communicates with the adsorption hole 201. The vacuum hole 3 is used to connect a negative pressure device to achieve vacuuming operation. When the external sight mirror workpiece is placed on the top, the workpiece can be stably fixed by negative pressure adsorption.

[0020] The curvature of the top of the support block 2 is adapted to the curvature of the workpiece, which realizes the close fit between the workpiece and the fixture. It provides a uniform and stable adsorption force during the cutting process, effectively resists the external force of cutting, and ensures that the workpiece does not shift during the cutting process. At the same time, it can avoid the problem of incomplete cutting caused by changes in focal length during laser cutting due to curvature mismatch.

[0021] In this embodiment, there are two vacuum holes 3. The adsorption platform 1 has two connecting channels 5 that correspond one-to-one with the vacuum holes 3. The connecting channels 5 are straight and connected to the vacuum holes 3. Each connecting channel 5 connects two adsorption holes 201 located on the same straight line, which realizes efficient distribution of negative pressure, so that the adsorption holes 201 on the same straight line can obtain uniform adsorption force, avoid local deformation of the workpiece caused by uneven adsorption force, and ensure the flatness of the cut surface.

[0022] In this embodiment, the adsorption holes 201 are all funnel-shaped with a larger top and a smaller bottom, which increases the contact area with the workpiece, makes the adsorption force distribution more uniform, and improves the adsorption stability.

[0023] In this embodiment, two limiting baffles 4 are provided at the edge of the adsorption platform 1 to limit the workpiece. The two limiting baffles 4 are fixed to two adjacent sides of the adsorption platform 1, providing a precise cutting reference for the workpiece. In use, simply place the external sight glass workpiece directly on the top of the four support blocks 2 and make the two adjacent sides of the workpiece abut against the limiting baffles 4 to quickly complete the workpiece positioning. The operation is convenient and efficient.
