Such a processing flow is cumbersome and inefficient, and the positioning accuracy is not high, and the reject rate is high. Traditional processing methods not only increase the labor intensity of workers, but also seriously affect the quality and production efficiency of products.

Contents of the invention

The utility model aims at the deficiencies of the existing technology, and provides a drilling fixture with high positioning accuracy, simple structure, convenient operation and practicality, which solves the problems of cumbersome operation, inconvenient positioning, and high labor intensity of workers in drilling processing.

The technical solution adopted by the utility model to solve the technical problems is: the new type of drilling machine fixture for drilling nut shells, the fixture includes a clamp body, a positioning and centering device, a clamping device and a tooling fixing device; The clamp body is the bracket of the fixture. The upper part is equipped with a positioning and centering device, the middle part has a clamping device, and the bottom has a tooling fixing device; the positioning and centering device includes an upward slope block, a drill sleeve and a drill template. The upward slope block is fixed on the drill template by screws Above, the drill sleeve and the drill template are clearance fit, the drill sleeve screw is used to prevent the movement and rotation of the drill sleeve, and the drill template is connected to the clamp body through positioning pins and screws; the clamping device includes a positioning mandrel, a downward slope block, Slotted gaskets and clamping nuts, the positioning mandrel is connected to the clamp body through threads, the downward slope block and the upward slope block are used together to position the workpiece, the positioning mandrel is used to place the workpiece, and the opening Both the slotted gasket and the clamping nut are installed on the positioning mandrel. The grooved design of the gasket facilitates the loading and unloading of the workpiece; the tooling fixture includes positioning keys, T-bolts and nuts, and the clamping body is positioned on the drilling machine through the positioning keys. On the platform, the clamp body is fixed on the drilling machine workbench by T-shaped bolts, and the fixing holes are open holes and counterbores.

The beneficial effects of the utility model are: the fixture is simple in structure, low in manufacturing cost, economical and practical; high in precision, the fixture is guided and positioned by a drill sleeve, and does not need to be marked by workers, which reduces the labor intensity of the workers and improves the safety of the workpiece. High precision; high production efficiency, no need for workers to mark lines, avoiding cumbersome procedures, and can process multiple holes at the same time; easy loading and unloading, as long as the clamping nut is loosened and the slotted gasket is removed, the workpiece can be removed; Easy to use, easy to operate, save man-hours, improve production efficiency and reduce costs.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments, wherein the schematic embodiments and descriptions are only used to explain the utility model, but not as a limitation to the utility model.

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a new type of drilling machine fixture for drilling nut shells, the fixture includes a fixture body 2, a positioning centering device, a clamping device and a tooling fixture; The clamp body 2 is the bracket of the fixture, the upper part is equipped with a positioning and centering device, the middle part has a clamping device, and the bottom has a tooling fixing device; the positioning and centering device includes an upward inclined block 4.1, a drill sleeve 6 and a drill template 3, and the upward inclined block 4.1 passes through Screws fix it on the drill template 3, the drill sleeve 6 and the drill template 3 are clearance fit, the drill sleeve screw 7 is used to prevent the drill sleeve 6 from moving and rotating, and the drill template 3 is connected to the clamp body 2 through positioning pins and screws Above; the clamping device includes a positioning mandrel 12, a downward slanting block 4.2, a slotted washer 10 and a clamping nut 11. The positioning mandrel 12 is connected to the clamp body 2 through threads, and the downward slanting block 4.2 and the upward slanting block 4.1 Used in conjunction with the positioning of the workpiece, the positioning mandrel 12 is used to place the workpiece, the slotted gasket 10 and the clamping nut 11 are installed on the positioning mandrel 12, and the design of the slotted gasket 10 is convenient The loading and unloading of the workpiece 8; the tooling fixing device includes a positioning key 13, a T-shaped bolt 1 and a nut, the clamping body is positioned on the drilling machine workbench by the positioning key 13, and the clamping body is fixed on the drilling machine workbench by the T-shaped bolt 1. The holes are open and counterbore.

When the utility model is in use, the clamp body 2 is accurately positioned on the drilling machine workbench by the positioning key 13, and then fastened on the drilling machine workbench with the T-bolt 1. Install the workpiece, remove the slotted gasket 10, put the workpiece on the positioning mandrel 12, and close to the step of the positioning mandrel 12, place the lower inclined block 4.2 under the upper inclined block 4.1, and knock it a few times Down-slope block 4.2, after positioning, tighten the clamping nut 11, apply the drill bit to the workpiece 8 through the drill bushing 6 for drilling, after processing, loosen the clamping nut 11, remove the slotted gasket 10, pull out the lower Inclined block 4.2, the processed workpiece can be unloaded. The drill sleeve 6 and the positioning mandrel 12 are wearable parts, which must be replaced if worn to a certain extent, otherwise the positioning accuracy will be affected. The inclined block 4 also wears out, but it has automatic compensation capability, which reduces the frequency of its replacement. Compared with traditional processing, this specific embodiment does not need marking and marking, saves time and effort, is convenient to operate, has a simple structure, improves production efficiency, reduces reject rate, and reduces production cost.
