Detailed Description

The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.

Referring to fig. 1 to 4, the drilling jig for the right-angle nameplate hole comprises a positioning plate 1 and a drilling template 2 which are perpendicular to each other, wherein a plurality of positioning holes 3 are formed in the positioning plate 1, and at least two positioning holes 3 are matched with screw holes in a mechanical part and used for screwing in bolts to position the drilling jig; the drilling template 2 is provided with a circular through hole 4, a fixed wheel sheet 5 is arranged at the position of the through hole 4, the through hole 4 is not shielded in the middle of the fixed wheel sheet 5, a plurality of sliding grooves 6 are radially arranged on the wheel surface of the fixed wheel sheet 5, pressing rods 7 are movably arranged in the sliding grooves 6, pressing parts 8 for fixing a drilling template sleeve 19 are arranged at the inner ends (the ends facing the circle center) of the pressing rods 7, a movable wheel sheet 9 is rotatably connected on the fixed wheel sheet 5, the movable wheel sheet 9 and the fixed wheel sheet 5 are arranged at the same circle center, strip-shaped holes 10 with the same number as the pressing rods 7 are arranged on the wheel surface of the movable wheel sheet 9, the strip-shaped holes 10 are obliquely arranged (the distance from one end to the other end of the strip-shaped hole 10 to the circle center is uniformly changed), each pressing rod 7 is provided with a protruded column 11, the diameter of each protruded column 11 is just matched with the width of the strip-shaped hole 10, the protruded columns 11 are inserted into the strip-shaped holes 10 one to one, all the protruding columns 11 are located on the same circumferential line of the movable wheel piece 9 under the limitation of the strip-shaped holes 10, and when the movable wheel piece 9 is rotated, all the protruding columns 11 synchronously move inwards or outwards in the radial direction, so that the pressing rod 7 is driven to move inwards or outwards in the radial direction along the sliding groove 6.

In the invention, two through holes 4 and two corresponding fixed wheel sheets 5 and two corresponding movable wheel sheets 9 are arranged, a movable toothed plate 12 is arranged on the drilling template 2, the toothed plate 12 is positioned between the two movable wheel sheets 9 and is meshed and connected with the two movable wheel sheets 9, and when the toothed plate 12 moves, the two movable wheel sheets 9 are driven to rotate simultaneously, so that all the pressing rods 7 on the two fixed wheel sheets 5 are driven to synchronously move inwards or outwards along the sliding groove 6 in the radial direction. It should be noted here that, since the rotation directions of the two movable wheel pieces 9 are opposite, in order to ensure that all the pressing rods 7 move inwards or outwards along the sliding chute 6 in the radial direction synchronously, the strip-shaped holes 10 on the two movable wheel pieces 9 need to be arranged in opposite inclined directions.

In the invention, a guide groove 13 is formed on the toothed plate 12 along the moving direction of the toothed plate, a guide plate 14 is arranged on the drilling template 2, and the guide plate 14 is movably embedded in the guide groove 13. The end of the toothed plate 12 is provided with a pull rod 15 for driving the toothed plate 12 to move. When the toothed plate 12 is pulled, the guide plate 14 of the toothed plate 12 can move along the guide groove 13, so that the stability of the toothed plate 12 is improved.

In the invention, six sliding grooves 6, corresponding pressing rods 7, pressing parts 8 and strip-shaped holes 10 are arranged and are uniformly distributed along the circumferential direction of the fixed wheel sheet 5 or the movable wheel sheet 9.

In the invention, the fixed wheel sheet 5 is provided with the annular slide rail 16, the driving wheel sheet 9 is rotatably connected with the annular slide rail 16, and the movement of the pressing rod 7 in the chute 6 cannot be influenced by the rotation of the driving wheel sheet 9.

Referring again to fig. 5, there is shown a mechanical part requiring the mounting of a nameplate at the right angle corner of its top end. Before drilling, corresponding the positioning hole 3 on the positioning plate 1 to a screw hole on a part, screwing a bolt to complete positioning, and enabling the center position of a through hole 4 on the drilling template 2 to correspond to the position to be drilled; then, the pull rod 15 is pulled upwards to drive the toothed plate 12 to move upwards, the two movable wheel sheets 9 are driven to rotate towards opposite directions, under the limiting action of the strip-shaped hole 10, the protruding column 11 and the pressing rod 7 and the pressing portion 8 connected with the protruding column move outwards in the radial direction, the pressing portion 8 diffuses outwards, the drill jig sleeve 19 with a proper size is placed in the middle of each pressing portion 8, then the pull rod 15 is loosened, after the loosening, each pressing rod 7 can move towards the circle center along the sliding groove 6 under the action of the spring 18 in the sliding groove 6 (at this time, the position of the protruding column 11 in the strip-shaped hole 10 can be changed, the two movable wheel sheets 9 are driven to rotate, and the toothed plate 12 correspondingly moves downwards), so that the pressing portion 8 is pressed outside the drill jig sleeve 19 at the same time, that the installation of the drill jig sleeve 19 is completed, and the drill jig sleeve 19 can automatically fall at the circle center position. The spring 18 is required to have enough elasticity to ensure that the drill jig sleeve 19 does not fall off during the drilling process. When the drill die sleeve 19 needs to be replaced, the operation is repeated, and the operation is very convenient.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
