Problems solved by technology
[0003] In the prior art, a simple V-shaped block fixture is usually used for positioning when drilling, and the following problems exist in the process: First, because the hole is drilled on an inclined surface, it is easy to shake, making the L dimension unstable, the processing effect is not good, and even the parts are damaged. Second, when drilling on an inclined surface, the drill bit is easily broken due to uneven force, which is likely to increase the processing cost; third, the operation convenience is poor and the use efficiency is not high
Many of the above disadvantages seriously affect the clamping of the hexagonal bolt head inclined plane drilling

The invention discloses a hexagonal bolt head inclined plane drilling fixture. The hexagonal bolt head inclined plane drilling fixture comprises a left positioning block (1), a left guide sleeve (3),a linkage rod (9) and a handle assembly (11), and is characterized in that the left positioning block (1) and a right positioning block (7) are arranged on a base (10), the lateral sides of the left positioning block (1) and right positioning block (7) are provided with a left guide sleeve (3) and a right guide sleeve (6) correspondingly, a mounting cavity (12) is formed between the left guide sleeve (3) and the right guide sleeve (6), the left guide sleeve (3) and the right guide sleeve (6) are provided with drill mounting holes (5) correspondingly, a stopping block (4) is arranged on the back of the left guide sleeve (3) and right guide sleeve (6), the left positioning block (1) and the right positioning block (7) are matched with the internally mounted linkage rod (9) to realize opposite or backward movement, and a handle assembly (11) is arranged on the tail portion of the linkage rod (9). The hexagonal bolt head inclined plane drilling fixture is simple in structure, high in quality and efficiency and suitable for popularization and use in hexagonal bolt head inclined plane drilling clamping.
Description
technical field [0001] The invention belongs to the technical field of positioning and clamping devices, and in particular relates to a hexagonal bolt head inclined plane drilling fixture. Background technique [0002] Bolts are very important fasteners, which are indispensable in the daily production process, and hexagonal bolts are the most common type of bolts. For hexagonal bolts, it is sometimes necessary to drill the fuse hole on the bevel of the hexagonal head (such as figure 2 Shown), this type of hole generally includes two dimensions of diameter d and position L. [0003] In the prior art, a simple V-shaped block fixture is usually used for positioning when drilling, and the following problems exist in the process: First, because the hole is drilled on an inclined surface, it is easy to shake, making the L dimension unstable, the processing effect is not good, and even the parts are damaged. The second is to drill holes on an inclined surface, and the drill bit i...
