Embodiment 1

[0040] Embodiment 1: as Figure 1~Figure 3 As shown, a drilling jig for mower housing cover parts includes a bottom plate, a left baffle 2 and a cylindrical head adjustment support 19 are arranged on the bottom plate 1, and the left baffle is passed through 2 cylindrical pins 21 and hexagon socket head screws. 20 is connected and fixed, and a B-shaped fixed positioning pin 3 and an A-shaped fixed positioning pin 5 are installed on the left baffle 2 to realize the positioning of the parts with the side of the left baffle 2, which limits 6 degrees of freedom; on the bottom plate 1 The right side of the right side connects right baffle plate 14, and pressing device is installed above the right baffle plate 14, realizes that the position of parts remains unchanged during processing.

[0041] The above-mentioned B-type fixed positioning pin 3 and A-type fixed positioning pin 5 are fixedly connected on the left baffle plate 2 through cooperation, which is convenient and quick to ins...

Embodiment 2

[0045] Embodiment 2: When drilling, put the part on the clamp body, quickly locate it through the B-type fixed positioning pin 3 and the A-type fixed positioning pin 5, and use the smooth pressing block 12 of the screw fastening device to tighten it. Fix, quickly realize the installation of the fixture, and then put the fixture with the installed parts on the workbench of the radial drilling machine to realize the drilling process.

[0046] A method for using a drilling jig for a part of a lawnmower housing cover, comprising the following steps:

[0047] (1) Install the left panel on the base;

[0048] (2) Install the positioning pin and cylindrical head adjustment support to the left side plate;

[0049] (3) Install the screw clamping device on the right side plate and fix it with the bottom plate;

[0050] (4) Install the drill template on the left side plate and fix the drill sleeve;

[0051] (5) Place the part on the corresponding position on the clamp body for position...

Abstract

The invention discloses a drilling clamp for a shell cover part of a hay mower and a use method thereof. The drilling clamp comprises a base plate, a left baffle, a right baffle, a spiral clamping device, a positioning element and a drilling template. According to the invention, two positioning pins are arranged on the left baffle and the spiral clamping device is arranged on the right baffle, so that the parts can be quickly detached, the processing precision can be ensured, and the drilling efficiency can be greatly increased; and the drilling clamp has the characteristics of simple structure, low cost and convenience in detaching and maintaining.

Description

[0001] Technical field: [0002] The invention relates to a drilling jig for a shell cover part of a mower, and also relates to a method for using the drilling jig for a shell cover part of a lawn mower. [0003] Background technique: [0004] The fixture is an important part of the machining process system and an indispensable and important process equipment in the machinery manufacturing industry. It can ensure the quality of machining, improve production efficiency, reduce production costs, reduce labor intensity, and realize the automation of the production process. Fixtures can also change the use of the original machine tool and expand the scope of use of the machine tool to achieve multiple functions in one machine. Therefore, fixtures play an important role in machining, and the use of a large number of special fixtures provides necessary conditions for mass production. In the production process, the quality of the special fixture design directly affects the production ...
