[0023] The following is a detailed description of a drilling machine fixture for machining handle seat holes according to the present invention, with reference to the accompanying drawings.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a drill press jig for machining handle seat holes, the structure of which includes a jig body 1, a drill jig 2, lugs 3, a positioning assembly 5, a first positioning shaft 6, and a second positioning shaft 7. The upper end of the jig body 1 is provided with two lugs 3, and the drill jig 21 is hinged to the lugs 3 via pins 4. One side of the jig body 1 is a vertical surface, and the first positioning shaft 6 is located on the vertical surface of the jig body 1. The other side of the jig body 1 is an inclined surface, and the second positioning shaft 7 and the positioning assembly 5 are both located on the inclined surface of the jig body 1. Figure 7 , Figure 8 As shown, since one of the two machining holes of the handle seat 8 is a straight hole 82, the part is fixed by the first positioning shaft for drilling. The second hole that needs to be machined in the handle seat 8 is an inclined hole 83. The handle seat 8 is fixed by the second positioning shaft on the fixture body for machining the inclined hole 83. One fixture can machine two holes at different angles, which is efficient and cost-saving.

[0025] like Figure 3 As shown, the drill jig 2 includes a drill template 21 and drill jig holes 22. One end of the drill template 21 is provided with a hinge hole that mates with the pin 4. The drill template 21 has two drill jig holes, namely drill jig hole one 22 and drill jig hole two 23. When the drill template is flipped and placed above the first positioning axis, a straight hole 82 is machined through drill jig hole one 22. When the drill template is flipped and placed above the second positioning axis, an inclined hole 83 is machined through drill jig hole two 23.

[0026] After machining the straight hole 82 of the workpiece, another oblique hole 83 needs to be machined. To improve the reliability of fixing the workpiece, a positioning assembly 5 is provided at the lower part of the second positioning shaft 7. The positioning assembly 5 includes a base 51, a pressure cap 52, and a limiting ball 53. The base 51 is connected to the inclined surface of the fixture body 1 by four screws and two tapered pins 54. The pressure cap 52 is provided at the bottom of the base 51, and the limiting ball 53 is provided at the top of the base 51. A spring (not shown in the figure) is provided between the pressure cap 52 and the limiting ball 53, and the spring is placed in the inner cavity of the base 51. One end of the spring abuts against the inner end of the limiting ball 53, and the other end of the spring abuts against the pressure cap 52. The limiting ball 53 of the positioning assembly abuts against the straight hole of the workpiece, thereby fixing the workpiece.

[0027] The first positioning shaft 6 and the second positioning shaft 7 have the same structure. For example... Figure 5 As shown, the first positioning shaft 6 includes a fixing plate 61, a shaft body 62 and a nut 63. One end of the shaft body 62 is provided with the fixing plate 61. The fixing plate 61 is connected to the side wall of the fixture body 1 by fasteners. The other end of the shaft body 62 is provided with a thread that mates with the nut 63. The optical shaft section of the shaft body 62 is provided with a through hole 64 with a diameter larger than that of the drill bit.

[0028] The bottom wall of the fixture body 1 is provided with a keyway. The fixture body is positioned and mounted on the machine tool worktable via the keyway for drilling the handle seat. First, the handle seat 8 is inserted into the first positioning shaft 6. Using the straight surface of the fixture body 1 as the reference surface, the handle seat 8 is fixed with a nut. Then, the drill template 21 is flipped to the top of the handle seat, and the straight hole 82 of the handle seat is machined through the drill jig hole 22 on the drill template. After the straight hole is machined, the handle seat 8 is removed with a nut. The handle seat 8 with the straight hole machined is then inserted into the second positioning shaft 7. Using the inclined surface of the fixture body 1 as the reference surface, when the handle seat is inserted, the limiting ball 53 of the positioning component is supported by a spring and lifts the machined straight hole 82, limiting the position of the handle seat 8, thereby ensuring the accuracy of the machining angle of the inclined hole 83. The handle seat is then tightened with a nut, and the inclined hole of the handle seat is machined through the drill jig hole 23 on the drill template 21.

[0029] This utility model's fixture, by providing a straight surface and a positioning shaft on one side of the fixture body, satisfies the machining requirements for straight holes in the handle seat; by providing an inclined surface, a positioning shaft, and a positioning assembly on the other side of the fixture body, it satisfies the machining requirements for inclined holes in the handle seat. A single fixture can satisfy the machining requirements for both straight and inclined holes in the handle seat, resulting in high work efficiency while ensuring the required hole angles.

[0030] The above is only to illustrate some principles of the present application, and the present application is not limited to the specific structure and application range shown in the description, so all possible modifications and equivalents belong to the patent application of the present application.

[0031] In addition to the technical features described in the specification, the remaining technical features are known to those skilled in the art.
