In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention.

[0017] Below, the portable CNC lathe spindle testing device according to the embodiment of the utility model is described with reference to the accompanying drawings. Figures 1 to 4 As shown, the portable CNC lathe spindle testing device includes a spindle box 1 and a base 3, an electric telescopic rod 2 is provided between the spindle box 1 and the base 3 for connection, a detection shaft rod 7 is provided on one side of the spindle box 1, a knob 4 and a sleeve 5 are movable sleeved on the detection shaft rod 7, a mounting hole 701 is opened at one end of the detection shaft rod 7, and a plurality of clamping claws 6 are provided in the mounting hole 701.

[0018] Preferably, a control panel 301 is provided on the top of the base 3, and the control panel 301 is electrically connected to the electric telescopic rod 2. A battery is provided in the spindle box 1 for powering the control panel 301 and the electric telescopic rod 2. The spindle box 1 can detect and collect the rotation data of the detection shaft 7.

[0019] In a specific embodiment: when in use, first place the base 3 on the table of the lathe to be tested, and then control the electric telescopic rod 2 through the control panel 301 to adjust the height of the spindle box 1 so that it is at the same axis as the spindle to be tested, and then push the spindle box 1 to insert the spindle into the mounting hole 701 on the detection shaft rod 7, and connect the detection shaft rod 7 to the spindle through the clamp 6, and then start the spindle of the machine tool to be tested, and the detection shaft rod 7 is driven by the spindle to rotate synchronously, and then it is tested and inspected through the spindle box 1. The steps are simple, there is no need to disassemble the spindle, and the detection result is more accurate.

[0020] Preferably, a thread is provided on the side wall of the detection shaft 7, and the knob 4 is movably connected to the thread on the detection shaft 7. When the knob 4 is rotated, it will slide along the detection shaft 7 through the setting of the thread. A retaining ring 401 is provided at one end of the knob 4, and anti-slip grooves are provided on the surface of the knob 4 to facilitate its rotation. A slot 502 is provided at one end of the sleeve 5, and a plurality of through holes 702 are provided on the inner wall of the mounting hole 701. There are four clamping jaws 6, and a support rod 601 is provided on the top of the clamping jaw 6. The top of the support rod 601 is an inclined surface, and a buckle 602 is also provided on the top of the support rod 601.

[0021] Preferably, there are four through holes 702 which are equidistantly arranged in a surrounding manner. The support rod 601 is movably installed in the through hole 702, and the retaining ring 401 is embedded in the retaining groove 502 and can rotate. When the knob 4 rotates, the sleeve 5 can be driven to slide on the detection shaft 7 through the cooperation between the retaining ring 401 and the retaining groove 502.

[0022] Preferably, four sliding grooves 501 are equidistantly formed around the inner wall of the sleeve 5, and the buckle 602 is embedded in the sliding groove 501 and can slide.

[0023] Preferably, the slide groove 501 and the outer wall of the sleeve 5 are arranged at an angle, the inner diameter of the sleeve 5 changes from large to small, and the card slot 502 is located at the end with a smaller inner diameter of the sleeve 5. When the sleeve 5 slides to the left, the connection between the slide groove 501 on its inner wall and the buckle 602 will gradually approach the outer wall of the detection shaft rod 7, thereby driving the support rod 601 to be inserted into the mounting hole 701 of the detection shaft rod 7.

[0024] In a specific embodiment: when fixing the main shaft, by turning the knob 4, the sleeve 5 is driven to slide to the left. Since the inner diameter of the sleeve 5 changes from large to small, during the sliding process of the sleeve 5, the cooperation between the slide groove 501 and the buckle 602 will drive the support rod 601 to slide in the through hole 702, and the support rod 601 drives the clamping claw 6 to move toward the axis of the detection shaft rod 7. Therefore, when the sleeve 5 slides to the left, it will drive the four clamping claws 6 to approach each other, thereby clamping and fixing the main shaft, and fixing the main shaft to the detection shaft rod 7.

[0025] Working principle: When in use, first place the base 3 on the table of the lathe to be tested, and then control the electric telescopic rod 2 through the control panel 301 to adjust the height of the spindle box 1 so that it is at the same axis as the spindle to be tested, then push the spindle box 1 to insert the spindle into the mounting hole 701 on the detection shaft rod 7, and then turn the knob 4 to drive the sleeve 5 to slide to the left. Since the inner diameter of the sleeve 5 changes from large to small, during the sliding process of the sleeve 5, the cooperation of the slide groove 501 and the buckle 602 will drive the support rod 601 to slide in the through hole 702, and the support rod 601 drives the clamping claw 6 to move toward the axis of the detection shaft rod 7. Therefore, when the sleeve 5 slides to the left, it will drive the four clamping claws 6 to approach each other, thereby clamping and fixing the spindle, and fixing the spindle to the detection shaft rod 7. Then, the spindle of the machine tool to be tested is started, and the detection shaft rod 7 is driven by the spindle to rotate synchronously, and then it is tested and inspected through the spindle box 1. The steps are simple, there is no need to disassemble the spindle, and the detection result is more accurate.
