Description

Technical Field

[0001] The utility model belongs to the field of milling machine fixing jigs, and specifically relates to a magnetic fixing jig for a notebook computer shell. 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] Especially for laptop shells, most of the current laptop shells are made of plastic or aluminum, and the production process of aluminum shells mostly adopts stamping. After stamping, the edge of the workpiece needs to be further polished and refined. At present, negative pressure adsorption solutions are mostly used to fix this type of shell on the milling machine.

[0005] For laptop computer shells, the negative pressure adsorption solution is mainly fixed by setting adsorption points under the shell. If there are too few adsorption points, the overall adsorption will not be stable enough. At the same time, when the milling machine head is milling horizontally after cutting, the adsorption strength of the adsorption points may be insufficient. The cutter head may directly drive the shell to move on the fixture that fixes the shell, resulting in incomplete milling or over-milling, causing damage to the shell.

[0006] Therefore, a new solution is needed to enable a workpiece that is more suitable for the shape of a notebook shell to be fixed quickly, accurately and stably on a milling machine. Utility Model Content

[0007] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a magnetic fixing fixture for a notebook computer shell.

[0008] In order to solve the above problems, the technical solution adopted by the utility model is as follows:

[0009] A laptop computer shell magnetic fixing fixture includes a laptop computer shell, a fixing base and a pressure plate, wherein a shell base is arranged in the middle of the base, a shell limiting rod is arranged around the shell base, the shell is arranged on the shell base, a pressure plate positioning rod is arranged on the shell limiting rod, the pressure plate covers the shell, a magnetic attraction component is arranged at the bottom of the shell base, and a magnetic attraction component corresponding to the shell base is arranged inside the pressure plate.

[0010] The magnetic attraction component of the housing base is an electromagnet.

[0011] The magnetic attraction component inside the pressing plate is an iron block.

[0012] The pressure plate is divided into a stepped structure with two parts, the lower part of the pressure plate is smaller than the internal size of the shell, the edge of the lower part of the pressure plate is a downward inclined surface, the upper part of the pressure plate is smaller than the size of the lower part, and the structure of the upper part of the pressure plate matches the maximum pushing range of the pressure plate positioning rod.

[0013] A cylinder is arranged above the outer shell limiting rod, the cylinder is connected to the pressure plate positioning rod, and the cylinder can move toward the central part of the outer shell base.

[0014] The size of the shell base is smaller than that of the shell, the middle part of the structure formed by the shell limiting rod is the same size as the shell, and the part where the shell limiting rod contacts the shell is provided with a guiding inclined surface.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model replaces the traditional negative pressure adsorption type laptop computer shell fixing with a magnetic suction pressure plate type laptop computer shell fixing. The fixing force of the computer shell is more uniform, and stronger pressure can be applied to the computer shell, preventing the computer shell from running around when the cutter head of the milling machine is milling the vertical part of the edge of the computer shell, resulting in poor processing effect and damage to the workpiece. In addition, the edge of the pressure plate set in the middle part of the computer shell and the outer shell limit rod are designed with a beveled space in the part where the cutter head is milling, leaving a larger working space for the cutter head, and better avoiding the situation where the cutter head and the fixture for fixing the shell collide with each other.

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

[0022] like Figure 1 and Figure 2 As shown, the utility model mainly comprises a base 1 and a pressing plate 2, and a shell 3 of a laptop computer is clamped and fixed between the base 1 and the pressing plate 2.

[0023] like Figure 1 and Figure 3 As shown, the central part of the base 1 is provided with a shell base 8 for placing the shell 3. The size of the shell base 8 is slightly smaller than that of the shell 3. When the shell 3 is placed on the shell base 8, the outermost erected edge of the shell 3 protrudes from the shell base 8. On the periphery of the shell base 8, shell limiting rods 4 are respectively provided in each direction. Each shell limiting rod 4 surrounds the shell base 8 in the middle, and the size of the enclosed space is the same as the size of the outer side of the shell 3. When the shell 3 is placed on the shell base 8, the four sides can just contact with the shell limiting rod 4, and the parts where the shell limiting rod 4 contacts the shell 3 are all provided with inclined surfaces, so that the shell 3 can be placed on the shell base 8 more conveniently, and more working space can be reserved for the cutter head of the milling machine to avoid collision.

[0024] A pressure plate positioning rod 5 and a cylinder 6 are also arranged above the outer shell limit rod 4. The push rod of the cylinder 6 is connected to the pressure plate positioning rod 5, and the moving direction of the cylinder 6 is toward the central part of the outer shell base 8. During actual work, the pressure plate 2 can be pushed to the preset position where the pressure plate 2 and the outer shell 3 cover the most evenly.

[0025] A set of magnetic components is arranged on the housing base 8. The magnetic component used in this embodiment is an electromagnet 7 arranged at the center of the housing base 8, and a magnetic block 9 matching with it is arranged at a corresponding position inside the pressure plate 2. The magnetic block 9 in this embodiment is an iron block with a size matching the electromagnet 7. The specific distribution of the electromagnet 7 and the magnetic block 9 is as follows: Figure 2 and Figure 3 as shown in .

[0026] The structure of the pressing plate 2 is a stepped structure divided into two parts, the lower part of the pressing plate 2 is the part that is in direct contact with the outer shell 3. The shape of the lower part of the pressing plate is similar to the structure of the middle part of the outer shell 3, but the area is slightly smaller than the size of the middle part of the outer shell 3, and a downward inclined surface is also provided at the edge position of the lower part of the pressing plate. The function of the inclined surface is also to reserve more working space for the cutter head of the milling machine to avoid collision between the cutter head and the pressing plate 2.

[0027] The area of ​​the upper part of the pressure plate 2 is smaller than that of the lower part, and the shape of the upper part of the pressure plate 2 matches the pressure plate positioning rod 5 on the periphery of the shell base 8. When the cylinders 6 on all the shell limit rods 4 are fully expanded, the pressure plate positioning rod 5 reaches the preset position. At this time, the shape surrounded by each pressure plate positioning rod 5 is the shape of the upper part of the pressure plate 2. Through the coordinated operation of multiple pressure plate positioning rods 5, the pressure plate 2 is pushed to the preset optimal position.

[0028] During actual use, the cylinder 6 in the initial state is fully retracted. At this time, the pressure plate positioning rod 5 is above the outer shell limiting rod 4, and its end will not enter the range of the outer shell base 8. The user first puts the outer shell 3 into the range surrounded by the outer shell limiting rod 4, that is, above the outer shell base 8. At this time, the outer shell 3 can be easily placed therein through the inclined surface of the outer shell limiting rod 4.

[0029] After the housing 3 is placed, the pressing plate 2 is placed on top of the housing 3. At this time, the cylinder 6 is started, and the pressing plate 2 is pushed to the predetermined working area through the joint work of the pressing plate positioning rods 5 in all directions. Then the electromagnet 7 is started, and the magnetic force generated by the electromagnet 7 is pulled to pull the magnetic block 9 set inside the pressing plate 2, so that the pressing plate 2 is firmly fixed on the base 1, and the housing 3 is clamped between the two. Finally, the cylinder 6 is controlled to retract the pressing plate positioning rod 5, and the milling machine head can start milling.

[0030] The utility model replaces the traditional negative pressure adsorption type fixation with a pressure plate magnetic attraction type fixation, so that the fixation is more reliable, and through the design of the shell limit rod 4 and the shell base 8, the shell 3 can be placed in the specified position to be processed more quickly.
