Specifically, the support arm upper surface has seted up one along its length direction and has supplied the spout of centre gripping arm embedding, centre gripping arm middle part has seted up a mounting groove that runs through along its length direction, wear to be equipped with at least one in the mounting groove be used for with the first bolt of the bottom surface butt of spout.

Furthermore, one end of the supporting arm, which is far away from the clamping arm, is provided with a large round hole through which a machine tool spindle can pass and a plurality of fixing holes which are distributed along the circumference of the large round hole and penetrate through the large round hole, and at least one of the fixing holes is internally provided with a second bolt used for fixing the supporting arm on the machine tool.

Furthermore, a reinforcing plate is fixedly arranged between the clamping arm and the motor.

According to the utility model, the supporting arm and the clamping arm arranged on the supporting arm in a sliding manner are adopted to extend the motor and the drill bit into the groove on the side surface of the workpiece, so that the bottom of the groove on the side surface of the workpiece is vertically drilled, and the problem that the bottom of the groove on the side surface of the workpiece cannot be vertically drilled in the prior art is solved.

Drawings

In order to more clearly illustrate the technical solution of the present invention, the drawings needed to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to the drawings without creative efforts.

FIG. 1 is a perspective view of an apparatus for vertically drilling the bottom of a groove in the side of a workpiece according to an embodiment of the present invention;

FIG. 2 is a top view of the apparatus of FIG. 1 for vertically drilling the bottom of a groove in the side of a workpiece.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in figure 1, the utility model provides a device for vertically drilling the bottom of a groove in the side surface of a workpiece, which comprises a supporting arm 1, wherein a clamping arm 2 is arranged on the supporting arm 1 in a sliding manner along the length direction of the supporting arm, a vertically arranged motor 3 is fixedly arranged at one end, far away from the supporting arm 1, of the clamping arm 2, and a rotating shaft of the motor 3 is fixedly connected with a vertically arranged drill bit 4.

The working principle of the device for vertically drilling the bottom of the groove in the side surface of the workpiece provided by the utility model is as follows: firstly, vertically and fixedly arranging a workpiece with a groove on the side surface on a machine tool workbench; then, sliding the clamping arm 2 to enable the motor 3 and the drill bit 4 to extend into a groove on the side face of the workpiece; then, the clamping arm 2 is continuously slid until the drill bit 4 is positioned above the position needing drilling in the groove on the side surface of the workpiece; and finally, the power supply is turned on, the motor 3 starts to work to drive the drill bit 4 to rotate at a high speed, the machine tool spindle drives the supporting arm 1 to move downwards, the drill bit 4 moves downwards along with the supporting arm, and when the drill bit 4 contacts the bottom surface of the groove in the side surface of the workpiece, the workpiece starts to be vertically drilled, so that the purpose of vertically drilling the bottom of the groove in the workpiece is achieved.

According to the utility model, the supporting arm 1 and the clamping arm 2 arranged on the supporting arm in a sliding manner are adopted to extend the motor 3 and the drill bit 4 into the groove on the side surface of the workpiece, so that the bottom of the groove on the side surface of the workpiece is vertically drilled, and the problem that the bottom of the groove on the side surface of the workpiece cannot be vertically drilled in the prior art is solved.

As shown in fig. 1, specifically, the upper surface of the support arm 1 is provided with a sliding groove 11 along the length direction thereof, into which the clamping arm 2 is embedded, the middle portion of the clamping arm 2 is provided with a through mounting groove 21 along the length direction thereof, and at least one first bolt 22 for abutting against the bottom surface of the sliding groove 11 is inserted into the mounting groove 21. When needs make the centre gripping arm 2 slide relative to support arm 1, the operator loosens first bolt 22 with the spanner, centre gripping arm 2 can slide relative to support arm 1 to adjust the length that centre gripping arm 2 stretched into work piece side recess, after the length that the centre gripping arm 2 stretched into work piece side recess was confirmed, operator's reuse spanner screwed up first bolt 22, thereby the distance that makes the regulation centre gripping arm 2 stretch into work piece side recess is fixed down, thereby the preparation to the vertical drilling in work piece side recess bottom has been done.

As shown in fig. 2, further, one end of the support arm 1 away from the clamping arm 2 is provided with a large circular hole 12 through which a spindle of a machine tool can pass and a plurality of fixing holes 13 distributed along the circumference of the large circular hole 12 and penetrating therethrough, and at least one of the fixing holes 13 is provided with a second bolt (not shown) for fixing the support arm 1 to the machine tool. When the supporting arm 1 and the clamping arm 2 need to be rotated to change the drilling position, an operator loosens the second bolt by using a wrench, the supporting arm 1 rotates around the main shaft of the machine tool, and when the supporting arm 1 rotates to a proper angle, the operator tightens the second bolt by using the wrench, so that the purpose of changing the drilling position without moving a workpiece is achieved.

As shown in fig. 1, further, a reinforcing plate 5 is fixedly arranged between the clamping arm 2 and the motor 3, and the reinforcing plate 5 can increase the firmness of the clamping arm 2 and the motor 3, so as to ensure the stability of the motor 3 and the drill 4 in the drilling process.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the utility model.
