Description

Fixtures for Drilling Pins

technical field

The utility model relates to a clamp, in particular to a clamp used for pin shaft drilling.

Background technique

Drilling operation is a common operation method in the manufacturing process of mechanical parts. The drilled holes are usually used for the circulation of various media or for the assembly of other parts, and the workpieces that need to be drilled are usually installed on the workbench with fixtures.

In the workpiece that needs to be drilled, the workpiece will be subjected to a large impact force of the drill bit during the drilling process, so the workpiece is usually placed and pressed on the operating table or the bottom plate of the fixture to avoid the strong impact force of the drill bit. The cutting station bounces open, which may cause danger or reduce productivity. From this point of view, the pin hole of the workpiece is matched with the fixture and pressed against the bottom plate. Such a structural design greatly limits the height of the workpiece and the distance from the pin hole of the workpiece to the bottom surface of the workpiece. When the distance between the pin shaft and the bottom plate of the fixture does not match, a new fixture needs to be replaced for drilling processing. For workpieces with the same pin hole size or the same center position of the pin hole, it may not be possible to share the same set of fixtures, but manufacturing different fixtures is inefficient and wastes resources.

Utility model content

Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present utility model more clear, the technical solutions in the embodiments of the present utility model will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described above are part of the embodiments of the present invention, but not all of the embodiments. The embodiments in the basic utility model, and all other embodiments obtained by those of ordinary skill in the art without creative work, fall within the protection scope of the present invention.

As shown in Figures 1 and 2, the figure includes a base 6, a column 1 is arranged on the base 6, a positioning transverse plate 2 is arranged on the upper end of the column 1, and a positioning hole for drilling a pin shaft is arranged on the positioning transverse plate 2 7. There are two tension rods 4 on the column 1, one of which is hinged to one end of the pressure plate 5, and the other end of the pressure plate 5 is connected to another tension rod through bolts. A fixing block 3 is arranged below the plate 2 .

The fixed block 3 is movably connected to the upright column 1 . Due to the different sizes of the pins to be processed, it may be necessary to adjust them during processing so that they correspond to the positioning holes 7 on the positioning transverse plate 2, so as to facilitate drilling on the pins.

As shown in Figure 3, the contact surface of the fixed block 3 with the pin shaft is V-shaped. In order to better fix the pin shaft, because the pin shaft is cylindrical, by setting the V-shaped contact surface, the pin shaft can be better clamped.

At least one positioning hole 7 is provided. The number of positioning holes 7 can be adapted to various types of pins for end face drilling, which is more practical.

Example

First, fix the fixture on the machine tool, fix it on the machine tool by bolts around the base 6, then place the pin to be processed on the base 6, paste a V-shaped surface of the fixing block 3, and adjust the position of the fixing block 3 , so that the pin shaft corresponds to the positioning hole 7 on the positioning horizontal plate 2, and finally clamps it through the hinged pressure plate 5, and the punching device on the machine tool passes through the positioning hole 7, and the pin shaft can be positioned.

The above descriptions are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited to this. Equivalent replacement or modification of the new technical solution and its utility model concept shall be included within the protection scope of the present utility model.
