DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-3 As shown, a drilling machine spindle with a hardness tester includes a spindle body 1 and a hardness tester 2. A height adjustment device 3 is provided on the spindle body 1. The movable end of the height adjustment device 3 is fixedly connected to a linear drive device 4. The detection probe 201 of the hardness tester 2 is fixed on the driving end of the linear drive device 4. A rangefinder 5 is installed on the shell of the linear drive device 4, wherein the linear drive device 4 is a cylinder.

[0024] In this embodiment, if Figure 1 As shown, the spindle body 1 moves with the driving system of the drilling machine, so the spindle body 1 can drive the detection probe 201 to move to the top of the workpiece to be detected. At this time, the rangefinder 5 can detect the distance between it and the workpiece, so that it is convenient for personnel to judge the distance between the detection probe 201 and the workpiece. Since the stroke of the linear drive device 4 is constant, the personnel can adjust the height of the linear drive device 4 through the height adjustment device 3 to ensure that the distance between the detection probe 201 and the workpiece meets the requirements. Then, the personnel control the linear drive device 4 to descend, so that the detection probe 201 presses down the workpiece, and then uses the hardness tester 2 to detect the hardness of the tool to complete the operation.

[0025] The height adjustment device 3 includes a reciprocating screw 302 and a plate 301 fixed to the side of the main shaft body 1. A limiting slot 304 is provided on the side of the plate 301 away from the main shaft body 1. The reciprocating screw 302 is located in the limiting slot 304 and the top passes through the plate 301. Positioning rings are respectively provided at the inner and outer positions of the plate 301. The two positioning rings limit the reciprocating screw 302 without affecting the rotation of the reciprocating screw 302 to prevent the height of the reciprocating screw 302 from changing. The bottom of the reciprocating screw 302 is rotatably connected to the bottom of the limiting slot 304 through a bearing 305. A matching wire block 303 is threadedly connected to the reciprocating screw 302. The wire block 303 is slidably connected to the limiting slot 304. The wire block 303 outside the limiting slot 304 is fixedly connected to the linear drive device 4.

[0026] like Figure 2 As shown, the reciprocating screw 302 can only rotate relative to the plate body 301, and the screw block 303 is limited by the limiting slide groove 304 and cannot rotate. Therefore, when a person rotates the reciprocating screw 302, the screw block 303 will be lifted and lowered in the limiting slide groove 304, thereby adjusting the height of the linear drive device 4, and then making the distance between the detection probe 201 and the workpiece meet the requirements.

[0027] Among them, Figure 3 As shown, the linear drive device 4 is connected to the distance meter 5 via a rotating assembly 6;

[0028] The rangefinder 5 can be rotated around the linear drive device 4 by the rotating assembly 6, thereby changing the corresponding position of the workpiece detected by the rangefinder 5, and then facilitating the movement of the spindle body 1 so that the rangefinder 5 points to the position to be detected of the workpiece, without the need for frequent reversal of the spindle body 1;

[0029] The rotating assembly 6 includes a limit ring 601 fixed to the periphery of the linear drive device 4, and an annular groove 602 is provided on the circumferential surface of the limit ring 601, and a sliding plate 603 is slidably connected in the annular groove 602. The rangefinder 5 is fixed to the bottom of the sliding plate 603, and the sliding plate 603 slides in the annular groove 602, so that the rangefinder 5 rotates around the periphery of the linear drive device 4, and the cross-sections of the limit ring 601 and the sliding plate 603 are T-shaped, so the limit ring 601 cannot be separated from the sliding plate 603, and the end of the sliding plate 603 located outside the annular groove 602 is threadedly connected with a locking screw 604, and the locking screw 604 is used to resist the annular groove 602. When the position of the sliding plate 603 is determined, the locking screw 604 is rotated so that the locking screw 604 resists the annular groove 602, thereby fixing the position of the sliding plate 603 to fix the rangefinder 5.

[0030] Working principle: first, fix the workpiece to be processed on the fixture of the drilling machine, and assemble the spindle body 1 with the drilling machine. When it is necessary to detect the hardness of the workpiece, use the driving system of the drilling machine to drive the spindle body 1 to move, thereby driving the detection probe 201 to move directly above the workpiece to be detected. At this time, the rangefinder 5 can detect the distance between it and the workpiece, so that it is convenient for personnel to judge the distance between the detection probe 201 and the workpiece. Then, the personnel rotates the reciprocating screw 302 to make the wire block 303 rise and fall in the limiting slide groove 304, and then adjust the height of the linear drive device 4 to ensure that the distance between the detection probe 201 and the workpiece meets the requirements at this time. In the next step, the personnel controls the linear drive device 4 to descend, so that the detection probe 201 presses down the workpiece, and then uses the hardness tester 2 to detect the hardness of the tool to complete the operation.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
