[0025] In the drill ear hole device, bottom plate 1 supports and fixes other components through multiple support mechanisms, and the device can be installed on the machine tool through bottom plate 1. The positioning mechanism is used to place the workpiece 15 (U-shaped groove hardware for composite insulator) to be processed. The front end of the locating block 6 is connected with the support mechanism and is supported and fixed by the support mechanism. The locating groove on the inner side of the rear end is matched with the shape of the flange (or upset head) of the tail part of the workpiece 15. The tail part of the workpiece 15 can extend into or partially extend into the locating groove. When the workpiece 15 is placed, the ear parts of the workpiece 15 are placed one above the other, and the tail part is placed into the locating groove. The lower ear is supported on the cushion block 9. Here, the upper side height of the cushion block 9 is consistent with the height of the lower ear part when the workpiece is centrally extended into the locating groove. The tight mechanism is used to fix the workpiece. The front end V-shaped mouth of the V-shaped block 12 faces the front end of the bottom plate 1, and the rear end is connected to the telescopic end of the tight cylinder 11. The V-shaped mouth of the V-shaped block 12 can clamp the front end of the two ear parts of the workpiece 15. After the workpiece is placed, the V-shaped block 12 can be moved towards the workpiece by the extension of the clamping cylinder. The V-shaped mouth can tightly clamp the workpiece, and at the same time, the workpiece is automatically centered, and the tail part is stably clamped into the locating groove. Here, the front and rear of the bottom plate 1 respectively refer to the left end and right end directions of the bottom plate 1 in the figure.

[0026] After the workpiece 15 is clamped and fixed, the drill bit can be extended from the drill hole 14 at the center of the drill template 13 to drill ear holes on the two ears of the workpiece 15. It should be noted that the distance between the drill hole 14 on the drill template 13 and the locating groove is consistent with the distance between the tail part of the workpiece 15 and the part to be drilled 14 on the two ears. In actual application, when installing the drill template 13, it is necessary to ensure that the position of the drill template 13 is directly above the cushion block 9, and the position of the drill hole 14 is directly above the part to be drilled 14 on the two ears of the workpiece 15. Based on the drill hole 14, the ear holes of the two ears of the workpiece 15 can be drilled at one time, and the concentricity of the two ear holes is ensured.

[0027] In an alternative embodiment, the positioning block 6 is supported by a first supporting mechanism, which comprises a front vertical plate 2 arranged at the front end of the base plate 1, the front vertical plate 2 having a through hole in the upper portion, and a transverse adjusting bolt 7, the front end of the transverse adjusting bolt 7 penetrating the front vertical plate 2 based on the through hole, the positioning block 6 being connected to the rear end of the adjusting bolt and supported on the base plate 1 by the transverse adjusting bolt 7 and the front vertical plate 2. Further, the transverse adjusting bolt 7 has two locking nuts 8 arranged on the two sides of the front vertical plate 2, respectively, and the position of the transverse adjusting bolt 7 on the front vertical plate 2 can be adjusted and locked by the two locking nuts 8. The position of the transverse adjusting bolt 7 can be adjusted by the two locking nuts 8, so that the position of the positioning block 6 can be adjusted, which can be suitable for workpieces of different lengths. Of course, the corresponding size of the positioning block 6 can also be replaced to adapt to the tail of different workpieces. In addition, the first supporting mechanism further comprises two inclined support plates 3, the bottoms of the two inclined support plates 3 being connected to the base plate 1, respectively, and the sides being connected to the two ends of the front vertical plate 2, respectively. The two inclined support plates 3 are used as supporting ribs to strengthen the front vertical plate 2, so as to improve the stability of the front vertical plate 2 in supporting the transverse adjusting bolt 7 and the workpiece.

[0028] The cushion block 9 is supported on the base plate 1 by a second supporting mechanism, which comprises a vertical adjusting bolt 10, the cushion block 9 being arranged at the top end of the vertical adjusting bolt 10, and the base plate 1 being provided with a threaded hole matched with the vertical adjusting bolt 10, the bottom end of the vertical adjusting bolt 10 being screwed into the threaded hole.

The position of the through hole on the rear vertical plate 5 corresponds to the position of the positioning groove, so that the jacking cylinder 11 can drive the V-shaped block 12 to jacking at the middle position of the front end of the workpiece 15.

[0031] According to the exemplary embodiment of the utility model, the tooling further comprises a drill bit and a driving mechanism thereof, after the workpiece 15 is placed on the positioning block 6 and the cushion block 9 and jacked by the cylinder, the drill bit can be used to extend into the drill hole 14 on the drill template 13, and the concentric drilling of the double ears of the workpiece 15 can be completed at one time. In actual application, the drill bit and the driving mechanism thereof can be part of a machine tool, and the drill ear hole device can also be assembled to the machine tool, for example, the base plate 1 is installed on the machine tool platform by bolts or rivets, so that the drilling of the ears of the workpiece 15 can be conveniently performed.

[0032] In an alternative embodiment, when the drill ear hole device is used to perform the drilling of the ears, first, in the preparation stage, the components in the drill ear hole device are set according to the specifications of the workpiece to be processed and assembled, and then the base plate 1 is installed on the machine tool platform; then, in the workpiece clamping stage, the front ear of the workpiece 15 is placed on the cushion block 9 so that the lower ear is attached to the cushion block 9, the tail of the workpiece 15 is aligned and placed in the positioning groove, and then the jacking cylinder 11 is started to make the V-shaped block 12 press the double ears of the workpiece 15 at the front end, so that the tail of the workpiece 15 is centered and extended into the positioning groove, and the positioning and clamping of the workpiece 15 are completed; then, in the drill ear hole stage, the drill bit is vertically extended downward from the drill hole 14 on the drill template 13 and started, the drill bit rotates to drill concentric ear holes on the two ears, and then the drill bit is stopped and retracted, and the workpiece 15 can be taken out. By repeating the workpiece clamping and drill ear hole steps, the production of batch drilling of the ears of the workpiece can be performed.
