Description

Technical Field

[0001] The utility model belongs to the field of milling machine fixing jigs, in particular to a notebook computer keyboard surface fixing jig. Background Art

[0002] Milling machine fixtures play a vital role in milling processing. Their main functions include clamping workpieces, improving production efficiency, and protecting workpiece surfaces.

[0003] A fixture that matches the workpiece can effectively improve the efficiency of workpiece processing and achieve fast and accurate workpiece installation. Depending on the required processing position, a fixed fixture dedicated to single-step processing can better adapt to a single processing workpiece and protect other parts of the workpiece according to actual processing needs.

[0004] The processing of each outer shell surface of a laptop computer is a relatively complex processing environment. The processing parts are different depending on the keyboard surface being processed. For example, for a keyboard surface with an outer wrapping structure on all sides, the main processing area is the outer wrapping structure part on the outside. The burrs and overflow parts at the end are removed and polished. However, since the overall surface is relatively thin and there are many keyboard button holes, it is not suitable to use a one-way extrusion clamp, which can easily cause the overall deformation of the board during the clamping process. The outer wrapping structure to be processed is prone to bending, causing the processing position to be skewed.

[0005] Therefore, a new solution for a fixing fixture used for processing the edge of a notebook keyboard surface is needed that is more suitable. Utility Model Content

[0006] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a laptop computer keyboard surface fixing fixture.

[0007] In order to solve the above problems, the technical solution adopted by the utility model is as follows:

[0008] A laptop computer keyboard surface fixing fixture comprises a laptop computer keyboard surface frame, a base and a pressure plate, the base is provided with a keyboard surface frame positioning block, a pressure plate positioning block and a pressure plate fixing frame, the shape and size of the keyboard surface frame positioning block are the same as the keyboard key grid of the keyboard surface frame, the pressure plate is arranged above the base, the pressure plate is provided with a plurality of cylinders pushed from the center toward the surroundings, the pressure plate is provided with positioning holes matching the pressure plate positioning block and the pressure plate fixing frame, and the keyboard surface frame is arranged between the base and the pressure plate.

[0009] The end of the cylinder is provided with a push rod perpendicular to the direction of the cylinder.

[0010] The keyboard frame positioning blocks are provided in four numbers and are arranged symmetrically according to the keyboard key grid on the keyboard surface frame.

[0011] The pressing plate is provided with a positioning groove which matches the positioning block of the keyboard frame.

[0012] The pressure plate positioning block is a cylindrical positioning column, and the height of the positioning column is higher than the thickness of the pressure plate.

[0013] The pressing plate fixing frame is a positioning column with a cross hanging ear, and the pressing plate fixing frame can be rotated.

[0014] The outer side of the base is provided with a cylinder which pushes toward the center of the base.

[0015] The cylinder pushing toward the center of the base is arranged on the side with the breakpoint on the edge of the keyboard surface frame.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The utility model replaces the clamp for fixing the laptop keyboard surface frame with a push rod that pushes from the center to the surroundings, which can fix the keyboard surface frame without deforming the keyboard surface frame, and can better fix the edge of the erected keyboard surface frame so that it will not move around during milling and is always in a state that is convenient for processing. At the same time, a pressure plate and multiple components that cooperate to perform positioning are used for joint positioning to ensure the overall accuracy during processing, and users can also more easily position and place the keyboard surface frame to be processed.

[0020] In the figure: 1. base; 2. pressure plate; 3. positioning hole; 4. frame positioning block; 5. pressure plate positioning block; 6. pressure plate fixing bracket; 7. cylinder; 8. push rod; 9. keyboard surface frame. DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with specific embodiments.

[0022] like Figure 1 As shown, the utility model mainly comprises two parts, namely a base 1 and a pressing plate 2 . When actually used, the keyboard surface frame 9 is located between the base 1 and the pressing plate 2 , and is pressed against the base 1 by the pressing plate 2 .

[0023] like Figure 2As shown, the base 1 is provided with an outer frame whose shape matches the keyboard surface frame 9, and the inner side of the outer frame is an arc that matches the keyboard surface frame 9. When the vertical edge of the keyboard surface frame 9 matches it, it is the preset position for milling. The edge of the keyboard surface frame 9 after stamping will be more or less bent, whether it is bent inward or outward, it will affect the milling effect, and the role of the outer frame is to limit the maximum distance of the edge bending outward, improve the yield rate of milling, and reduce the secondary rework caused by inadequate milling.

[0024] Inside the outer frame of the base 1, there are three components that assist in positioning the keyboard face frame 9 and the pressure plate 2, namely, the frame positioning block 4, the pressure plate positioning block 5 and the pressure plate fixing frame 6. The shape and size of the frame fixing block 4 are the same as the keyboard key grid in the keyboard face frame 9. When the frame fixing block 4 enters the keyboard key grid, it can just fill the keyboard key grid, and the keyboard face frame 9 can be preliminarily positioned to prevent it from moving around. In this embodiment, there are four frame fixing blocks 4 on the base 1, and they are symmetrically arranged, so that the user can find the approximate position of installing the keyboard face frame 9 more quickly when placing the workpiece.

[0025] The pressure plate positioning block 5 and the pressure plate fixing frame 6 are components used to position and fix the pressure plate 2, wherein the pressure plate positioning block 5 is a cylindrical positioning column, and the pressure plate 2 is provided with a positioning hole 3 of a size matching the positioning block 5. The pressure plate fixing frame 6 is a positioning column structure that can rotate and has a cross-shaped fixing ear at the upper end. Since the cross-shaped fixing ear structure is relatively large, it is set at the position of the space bar on the keyboard surface frame 9. At the same time, the position of the space bar is also in the center of the entire keyboard surface frame 9. The pressure plate 2 is fixed here, and a more uniform force can also be provided.

[0026] The pressing plate 2 is provided with a plurality of positioning holes 3 that match the frame positioning blocks 4, the pressing plate positioning blocks 5 and the pressing plate fixing frame 6. After the keyboard surface frame 9 is placed on the base 1, the pressing plate 2 is covered on the keyboard surface frame 9 through the positioning of several positioning components, and then the pressing plate fixing frame 6 is rotated to buckle the cross-shaped fixing ears on the pressing plate 2 to fix the pressing plate 2. At this time, the pressing plate 2 presses the keyboard surface part of the keyboard surface frame 9 tightly on the base 1, and after being fixed by the frame fixing block 4, it will not slide.

[0027] There are notches on the four directions of the edge of the pressing plate 2. The notches of the pressing plate 2 are used to place the push rod 8. Four cylinders 7 are arranged above the pressing plate 2. Each cylinder 7 is arranged corresponding to a direction. The end of the cylinder 7 is connected to the push rod 8. The push rod 8 can be pushed by starting the cylinder 7. The pushing direction is from the center of the pressing plate 2 toward the edges in four directions.

[0028] The thickness of the pressing plate 2 is higher than the height of the vertical edge of the keyboard surface frame 9, so the end of the push rod 8 set at the edge of the pressing plate 2 is designed to match the height of the keyboard surface frame 9, and the shape of the end of the push rod 8 is also an arc structure that matches the vertical edge of the keyboard surface frame 9. When the push rod 8 is pushed by the cylinder 7, the push rod 8 presses against the inner side of the edge of the keyboard surface frame 9 until the other side of the keyboard surface frame 9 contacts the outer frame on the base 1 and reaches the predetermined position. At this time, the keyboard surface frame 9 is finally fixed.

[0029] The four vertical edge structures on the keyboard surface frame 9 are not exactly the same. The edge structure located at the top is disconnected from the other two edge structures on both sides. At the same time, a more special arch structure is also provided on this section of the edge structure. It cannot be simply pushed outward by the cylinder 7 provided on the pressure plate 2, as this will easily deform the arch structure. Therefore, on the base 1 outside the edge, a cylinder 7 is provided for pushing in the opposite direction toward the center part of the pressure plate 2, and the push rod 8 provided on the cylinder 7 is also a special design for the arch structure. The two push rods 8 push each other until they are in the preset position and then stop pushing to perform milling work normally.

[0030] The structural design of the utility model is compact, but it is very simple to use in practice. The user can quickly complete the positioning and placement of the keyboard surface frame 9 and fix the pressure plate 2, which can be better positioned during milling, and due to the obstruction of the pressure plate 2, other positions that do not require milling will not be damaged.
