Description

Technical Field

[0001] This utility model relates to the field of clock surface processing technology, and in particular to a pretreatment device for watch mirror processing. Background Technology

[0002] In the manufacturing process of watch crystals (usually made of sapphire glass, mineral glass, or acrylic), pretreatment is a crucial step in ensuring the dimensional accuracy, surface quality, and damage resistance of the final product.

[0003] The raw materials (sapphire crystal ingots, glass plates, etc.) are cut into blanks that are close to the shape of the watch crystal. The blanks are then ground to a size close to the final shape. During the grinding process, the edges of the watch crystal need to be pre-processed to prevent chipping later. Generally, the sides of the watch crystal are pre-processed by a grinding machine. The watch crystal needs to be fixed during processing. However, the smooth surface of the watch crystal makes it easy for it to slip during the grinding process, thus reducing the effect of the pre-processing of the watch crystal's sides. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where the smooth surface of the watch crystal makes it easy to slip during the polishing process, thereby reducing the effect of the pre-treatment of the watch crystal side polishing. Therefore, this invention proposes a pre-treatment device for watch crystal processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a pretreatment device for watch mirror processing, including a base frame, a movable frame slidably connected inside the base frame, a support platform slidably connected to the upper end of the movable frame, a threaded hole on the movable frame, an adjusting component for adjusting the position of the support platform connected to the threaded hole, a limit frame connected to one side of the upper end of the support platform, a mounting plate fixedly connected to the upper end of the support platform, an electric telescopic rod fixedly connected to the upper end of the mounting plate, the telescopic end of the electric telescopic rod passing through the mounting plate and fixedly connected to a pressure plate, and electric vacuum suction cups connected to the four corners of the mounting plate.

[0007] Preferably, an anti-wear pad is fixedly connected to the bottom end of the base frame.

[0008] Preferably, the adjusting element is a threaded rod.

[0009] Preferably, one end of the adjusting member is fixedly connected to a turntable, and an anti-slip sleeve is fitted onto the turntable.

[0010] Preferably, a guide rod is fixedly connected to the upper end of the pressure plate, and the upper end of the guide rod passes through the mounting plate.

[0011] Preferably, the mounting plate and the support platform are an integral structure, and the mounting plate and the pressure plate are arranged in parallel.

[0012] Preferably, a debris collection mechanism is fixedly connected to the base frame. The debris collection mechanism includes a fan, which is fixedly connected to the base frame. The inlet end of the fan is connected to an air intake hopper through a first connecting pipe. The air intake hopper is located below the grinder.

[0013] Preferably, a filter box is fixedly connected to the base frame, and the outlet end of the fan is connected to the filter box through a second connecting pipe.

[0014] The pretreatment device for watch mirror processing proposed in this utility model has the following advantages:

[0015] After the electric telescopic rod is powered on, it moves the pressure plate downwards a set distance. The pressure plate then moves several electric vacuum suction cups downwards a set distance. The electric vacuum suction cups contact the upper surface of the clock face and, after being activated, adsorb and fix the clock face. With the cooperation of the limiting frame, the clock face is fixed and limited, so that the clock face will not slide during the processing. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1-4 A pretreatment device for watch mirror processing includes a base frame 1, with an anti-wear pad fixedly connected to the bottom end of the base frame 1. A movable frame 3 is slidably connected inside the base frame 1, and a movable groove 2 is formed on the movable frame 3, through which the movable frame 3 passes. A horizontal drive component 4 for moving the movable frame 3 horizontally is connected to the base frame 1. A support platform 5 is slidably connected to the upper end of the movable frame 3, and a threaded hole is formed on the movable frame 3. An adjusting component 6 for adjusting the position of the support platform 5 is connected to the threaded hole. The adjusting component 6 is a threaded rod, and a turntable is fixedly connected to one end of the adjusting component 6. An anti-slip sleeve is fitted on the turntable. A limit frame 7 is connected to one side of the upper end of the support platform 5. A mounting plate 8 is fixedly connected to the upper end of the support platform 5. An electric telescopic rod 9 is fixedly connected to the upper end of the mounting plate 8. The telescopic end of the electric telescopic rod 9 passes through the mounting plate 8 and is fixedly connected to a pressure plate 10. The mounting plate 8 and the support platform 5 are an integral structure. The mounting plate 8 and the pressure plate 10 are arranged parallel to each other. An electric vacuum suction cup 11 is connected to each of the four corners of the mounting plate 8. A guide rod 12 is fixedly connected to the upper end of the pressure plate 10. The upper end of the guide rod 12 passes through the mounting plate 8. A polishing machine 13 for processing the edge corner of the watch mirror is connected to the upper end of the base frame 1.

[0023] Work process:

[0024] The clock face is placed on the upper part of the support platform 5, with one side of the clock face contacting the limiting frame 7. The limiting frame 7 limits the clock face, causing the side of the clock face that needs to be polished to extend out of the support platform 5. After the electric telescopic rod 9 is powered on, it drives the pressure plate 10 to move downward a set distance. The pressure plate 10 drives several electric vacuum suction cups 11 to move downward a set distance. The several electric vacuum suction cups 11 contact the upper surface of the clock face. After the several electric vacuum suction cups 11 are activated, they adsorb and fix the clock face. With the cooperation of the limiting frame 7, the clock face is fixed and limited, so that the clock face will not slide during the processing.

[0025] Then rotate the turntable. The anti-slip sleeve increases the friction between the hand and the turntable. The turntable drives the adjusting component 6 to rotate. Under the limit of the threaded hole, the adjusting component 6 drives the support platform 5 to move. The support platform 5 drives the clock face to move towards the polishing machine 13, so that the side of the clock face contacts the polishing machine 13. After the polishing machine 13 starts, it polishes the side of the clock face. At the same time, after the horizontal drive component 4 is powered on and started, it drives the support platform 5 to move. The support platform 5 drives the clock face to move, so that the polishing machine 13 polishes along the length of the clock face.

[0026] Example 2: When polishing the side of the clock face crystal with polishing machine 13, the polishing debris is scattered and inconvenient to collect. (Refer to...) Figure 2 As another preferred embodiment of this utility model, the difference from embodiment 1 is that a debris collection mechanism 14 is fixedly connected to the base frame 1. The debris collection mechanism 14 includes a fan 141, which is fixedly connected to the base frame 1. The inlet end of the fan 141 is connected to an air intake hopper 142 through a first connecting pipe. The air intake hopper 142 is located below the grinder 13. A filter box 143 is fixedly connected to the base frame 1. The outlet end of the fan 141 is connected to the filter box 143 through a second connecting pipe.

[0027] After the blower 21 is powered on and started, a negative pressure is generated in the air intake hopper 22. The negative pressure collects the debris generated during grinding. The collected debris is introduced into the filter box 143 through the second connecting pipe. The filter box 143 filters the debris particles in the introduced gas to prevent the debris from scattering and facilitates collection.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
