Description

Technical Field

[0001] The utility model relates to the technical field of mobile hard disk shell processing, in particular to a mobile hard disk shell numerical control processing fixture. Background Art

[0002] Mobile hard disk mainly refers to a small and portable hard disk storage device that uses USB or IEEE1394 interface and can be plugged in or unplugged at any time. It can transfer data with the system at a high speed. On products with USB1.1 interface specification, it takes a long time to transfer a large amount of data. Advantages of mobile hard disk: large capacity, good compatibility, plug and play, fast speed, small size, small quality, safe and reliable.

[0003] The mobile hard disk casing needs to be positioned using a specific fixture during processing to facilitate subsequent processing. Since the hard disk product has a flat surface, it is easy to deform the product and damage the outer surface of the product when clamped in place, and it is easy to cause the product to be eccentric, which urgently needs to be developed.

[0006] Preferably, a mobile hard disk housing is movably provided inside the upper template, and the mobile hard disk housing is sleeved on the outside of the active slider and the left and right slider bodies.

[0007] Preferably, three groups of spring positioning steel balls are evenly and symmetrically arranged inside the active sliding block, and the three groups of spring positioning steel balls are provided with six in total.

[0008] Preferably, the active slider is slidably connected to the left and right slider bodies.

[0009] Preferably, left and right slider limit screws are symmetrically arranged in the bottom of the left and right slider bodies.

[0010] Preferably, the left and right slider bodies are internally positioned and connected to the upper template via left and right slider limit screws.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) This kind of mobile hard disk housing CNC machining fixture effectively prevents the appearance, deformation, eccentricity and other defects of the mobile hard disk housing during the machining process through the positioning mechanism. The arrangement of the active slider and the left and right slider bodies realizes accurate positioning up and down, left and right, good rigidity, stable machining quality, and an overall yield rate increased by 41%, and the yield rate can reach 99%;

[0013] (2) This type of CNC machining fixture for mobile hard disk housing can clamp 8 products at a time, reducing the clamping time, improving the overall efficiency by 25%, and reducing the labor intensity of workers. The original screw clamping method is changed to a pneumatic clamping method, preferably a cylinder group, so that 8 products can be clamped and released at the same time. Workers only need to take and place the products, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5The utility model provides an embodiment: a CNC machining fixture for a mobile hard disk housing, comprising an upper template 1, a cylinder 4, an active slider 6 and left and right slider bodies 10, wherein the four corners of the bottom of the upper template 1 are fixed with support columns 2, the bottom of the upper template 1 is connected to the lower template 3 through the support columns 2, and eight cylinders 4 are installed on the surface of the top of the lower template 3 at equal intervals, and the driving end of the top of the cylinder 4 is connected to a connecting block 5, and the connecting block 5 is used to connect the cylinder 4 and the active slider 6;

[0022] The top of the connecting block 5 is internally connected with an active slider 6, and the active slider 6 and the mobile hard disk housing 7 are externally shaped to be tilted upward by 15 mm, and the active slider 6 has a sliding range of 15 mm upward;

[0023] The two sides of the active slider 6 are symmetrically provided with left and right slider bodies 10 , and the sliding range of the left and right slider bodies 10 is 2 mm horizontally.

[0024] A mobile hard disk housing 7 is movably provided inside the upper template 1 , and the mobile hard disk housing 7 is sleeved on the outside of the active slider 6 and the left and right slider bodies 10 .

[0025] Three groups of spring positioning steel balls 9 are symmetrically arranged at equal intervals inside the active slider 6 . There are a total of six spring positioning steel balls 9 in the three groups. The arrangement of the spring positioning steel balls 9 plays a role in front and back positioning of the inner cavity of the mobile hard disk housing 7 .

[0026] The active slider 6 is slidably connected to the left and right slider bodies 10 .

[0027] Left and right slider limit screws 8 are symmetrically arranged at the bottom of the left and right slider bodies 10. The left and right slider limit screws 8 are arranged to limit the left and right slider bodies 10 from being moved upward by the active slider 6 so that they can only move horizontally.

[0028] The left and right slider bodies 10 are positioned and connected to the inner part of the upper template 1 through the left and right slider limit screws 8 .

[0029] When the embodiment of the present application is in use: the cylinder 4 moves upward to push the main active slider 6 upward, and at the same time, the left and right slider bodies 10 move toward the center of the upper template 1 due to the effect of the inclined surface, so that the center distance between the two left and right slider bodies 10 becomes smaller, which is equivalent to the size of the sliding mechanism becoming smaller. When it is smaller than the inner cavity of the mobile hard disk casing 7, the mobile hard disk casing 7 can be inserted into the top of the upper template 1 and the outside of the active slider 6 and the left and right slider bodies 10. When the cylinder 4 moves downward, the active slider 6 is pulled downward, and the left and right slider bodies 10 are stretched outward to tighten the inner cavity of the mobile hard disk casing 7. After the processing of the mobile hard disk casing 7 is completed, the cylinder 4 moves upward to take out the mobile hard disk casing 7.
