Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

The utility model provides a double-hole gasket batch drilling tool which can simultaneously position a plurality of stacked gaskets 100, and has the structure shown in fig. 1 and 2, and comprises a bottom plate 1, a limiting seat 2 and a pressing mechanism 3, wherein the positions, corresponding to double holes of the gaskets 100, on the bottom plate 1 are provided with abdication holes 10; the limiting seat 2 is fixedly arranged on the bottom plate 1, and a limiting groove 20 with a notch is formed in the side surface of the limiting seat 2 and is used for placing a stack of washers 100 and positioning the washers from the horizontal direction; the pressing mechanism 3 is used for pressing the stack of washers 100 placed in the limit groove 20 on the upper surface of the bottom plate 1 so as to position the stack of washers 100 vertically.

In the double-hole gasket batch drilling tool, the limiting groove 20 can be used for placing a stack of gaskets 100, the pressing mechanism 3 can be used for pressing the stack of gaskets 100 placed in the limiting groove 20, so that the stack of gaskets 100 can be positioned, and a plurality of gaskets 100 in the stack can be drilled at the same time, so that the drilling efficiency of the gaskets 100 is improved; and, the limit groove 20 is formed on the side surface of the limit seat 2, so that the limit seat is provided with a notch, which is convenient for taking and placing the gasket 100.

With continued reference to fig. 1, as a specific embodiment, the limiting groove 20 is an arc groove or a V-shaped groove.

It will be appreciated that by providing the limiting groove 20 as an arc-shaped groove or a V-shaped groove, it is possible to adapt to washers 100 of different diameters.

Referring to fig. 2, in order to avoid misalignment of the stacked washers 100 when an external force is applied, which results in poor accuracy of drilling, as a preferred embodiment, the dual hole washer batch drilling tool further includes a fastening assembly 4 for fastening the stacked washers 100 together, the fastening assembly 4 includes a bolt 41 and a nut 42, and the top end of the bolt 41 is threaded with the nut 42 after passing through the central hole of the stacked washers 100.

It will be appreciated that the bolt 41 cooperates with the nut 42 to fasten the stack of washers 100 together, so that the stack of washers 100 placed in the limiting groove 20 is prevented from being displaced from each other when subjected to an external force, which is advantageous in ensuring the accuracy of drilling.

Specifically, the pressing mechanism 3 includes a mounting seat 31 and a pressing arm 32, the mounting seat 31 is fixedly disposed on the bottom plate 1, and one end of the pressing arm 32 is hinged to the mounting seat 31.

It will be appreciated that pressing down the pressing arm 32, i.e. pressing the stack of washers 100 against the bottom plate 1, enables a vertical positioning of the stack of washers 100.

Further, the pressing mechanism 3 further includes a hand guard (not shown) fixedly sleeved on the outer surface of the pressing arm 32.

In order to enable the pressing arm 32 to automatically return to the initial position after the operation is finished, so as to avoid interference with the insertion and the extraction of the gasket 100 in the limit slot 20, as a preferred embodiment, the pressing mechanism 3 further includes a torsion spring (not shown in the figure), and one end of the pressing arm 32 is hinged to the mounting seat 31 through the torsion spring.

It will be appreciated that after the drilling operation is finished, the pressing arm 32 is loosened, and under the action of the elastic force of the torsion spring, the pressing arm 32 can be driven to return to the initial position, so that the interference to the putting in and taking out of the gasket 100 in the limit groove 20 can be avoided, the pressing arm 32 is also prevented from being lifted by manpower, and the workload of workers is reduced.

It should be noted that, since the prior art is that one end of the pressing arm 32 is hinged to the mounting seat 31 through a torsion spring, a connection structure between the torsion spring and the pressing arm 32 and a connection structure between the torsion spring and the mounting seat 31 are not specifically described.

In order to avoid abrasion caused by direct contact between the pressing arm 32 and the washers 100 when pressing the stack of washers 100, the pressing mechanism 3 further includes, as a preferred embodiment, a pressing plate 33, where the pressing arm 32 is located on a side above the limit slot 20, and the pressing plate 33 is fixedly connected to a side of the pressing arm 32 near the limit slot 20.

Since one end of the pressing arm 32 is hinged to the mounting seat 31, when the pressing arm 32 is pressed down by a force, the pressing arm 32 or each part of the pressing plate 33 is in different horizontal planes, so that the uneven stress on the gasket 100 is caused, and in order to avoid the gasket 100 tilting to one side due to the uneven stress, as a preferred embodiment, the pressing mechanism 3 further includes an elastic pad 34, where the elastic pad 34 is fixedly disposed at the bottom of the pressing plate 33, and specifically, the elastic pad 34 is a rubber elastic pad.

It can be appreciated that, by fixedly arranging the elastic pad 34 at the bottom of the pressing plate 33, when the elastic pad 34 contacts with the gasket 100, deformation of different degrees can be generated according to different pressures, so that each part of the gasket 100 can be guaranteed to bear force, and the situation that the gasket 100 is tilted to one side is avoided.

For the convenience of understanding the present utility model, the following describes the working principle of the present solution in detail with reference to fig. 1 and 2:

in operation, the bolts 41 and the nuts 42 are used to fasten the stack of washers 100 together, specifically, the top ends of the bolts 41 sequentially pass through the stacked washers 100 and then cooperate with the nuts 42, and the nuts 42 are tightened to press the stack of washers 100 against each other.

Placing a stack of washers 100 into the limiting groove 20, taking care that holes to be drilled of the washers 100 correspond to the relief holes 10, and placing the tail ends of the bolts 41 into the relief holes 10; pressing down the pressing arm 32 to rotate around the hinge of the pressing arm and the mounting seat 31 until a stack of washers 100 is pressed against the base plate 1; the drilling machine is started, i.e. the drilling operation can be performed.

After the drilling is finished, the pressing arm 32 is loosened, the torsion spring drives the pressing arm 32 to return to the initial position by means of elasticity, a stack of washers is taken out from the limiting groove 20, and then the bolt 41 and the nut 42 are detached.

The above-described embodiments of the present utility model do not limit the scope of the present utility model. Any of various other corresponding changes and modifications made according to the technical idea of the present utility model should be included in the scope of the claims of the present utility model.
