[0040] Embodiment two

[0041] As shown in the drawings, on the basis of the embodiment one, the utility model also proposes a structure for driving the tool holder 3 to move horizontally. Figures 1-3

[0042] The base 1 is provided with a driving mechanism 2 for driving the tool holder 3 to move horizontally along the X axis or / and the Y axis, the driving motor 405 for driving the rotating shaft 402 to rotate around the axis of the rotating shaft 402 is arranged on one side of the driving mechanism 2, and the microscope 7 is located above the driving mechanism 2.

[0043] The driving mechanism 2 comprises a frame 201 fixedly installed on the base 1, the inner side of the frame 201 is provided with a support plate 202 capable of moving horizontally along the X axis, the support plate 202 is provided with a sliding seat 203 capable of moving horizontally along the Y axis, and the tool holder 3 is fixedly installed on the sliding seat 203; the top of the support plate 202 is fixedly installed with a second sliding rail 205 parallel to the Y axis, and the sliding seat 203 is slidingly installed on the second sliding rail 205. The support plate 202 drives the tool holder 3 and the sliding seat 203 to move horizontally along the X axis, and the sliding seat 203 drives the tool holder 3 to move horizontally along the Y axis relative to the support plate 202.

[0044] ​The frame 201 is in a rectangular structure, and a screw rod 206 parallel to the X-axis direction is rotatably arranged inside the frame 201. A nut 207 is screwed on the screw rod 206, and the nut 207 is fixedly connected with the support plate 202. The two sides of the screw rod 206 are both provided with a first sliding rail 204 parallel to the X-axis direction, and the support plate 202 is slidably arranged on the first sliding rail 204.

[0045] One end of the screw rod 206 penetrates the frame 201 and is connected with the rotating handle 13. Rotating the rotating handle 13 can drive the screw rod 206 to rotate. The screw rod 206 is screwed with the nut 207, so that the nut 207 can reciprocate along the axis direction of the screw rod 206 with the rotation of the screw rod 206. The nut 207 is fixedly connected with the support plate 202, so that the nut 207 drives the support plate 202 to move along the X-axis direction under the guidance of the first sliding rail 204.

[0046] The support plate 202 is fixedly provided with a fixed block 11, and the fixed block 11 is connected with the sliding seat 203 through a tension spring 12. One end of the tension spring 12 is fixedly connected with the fixed block 11, and the other end is fixedly connected with the sliding seat 203. The fixed block 11 can limit the movement distance of the sliding seat 203 along the second sliding rail 205. The tension spring 12 plays a resetting role to ensure that the cutter 10 can retreat to a safe position in time after cutting the product.

[0047] The sliding seat 203 is fixedly provided with an elongated rod 209 parallel to the Y-axis direction on one side, and the frame 201 is externally provided with a limiting assembly 208. The end of the elongated rod 209 can abut against the output end of the limiting assembly 208, and the limiting assembly 208 is used for adjusting the cutting depth of the cutter 10.

[0048] The limiting assembly 208 adopts an existing locking structure, such as a micrometer with a self-locking knob. By rotating the knob, the output end can be extended and retracted along the axis direction and can abut against the elongated rod 209. The elongated rod 209 extends to the outside around the frame 201. When working, the sliding seat 203 is manually pushed to move along the Y-axis direction to approach the limiting assembly 208. In this process, the tension spring 12 is stretched. After cutting the workpiece 9, the sliding seat 203 is released, and the tension spring 12 pulls the sliding seat 203 back to a safe position. Under the joint action of the elongated rod 209 and the limiting assembly 208, the cutting depth of the cutter 10 can be limited to avoid the risk of hitting the cutter, that is, to avoid the collision between the cutter 10 and the clamping part 409.

[0049] In addition, the tool holder 3 can also be adjusted up and down along the Z-axis direction relative to the sliding seat 203, so as to fully utilize the cutting edge of the cutter 10. A long waist hole is formed in the tool holder 3, and the length direction of the long waist hole is parallel to the Z-axis. After a screw is installed on the sliding seat 203 through the long waist hole, the range of distance adjustment of the tool holder 3 can be controlled. When the screw is locked, the height of the tool holder 3 is locked.

[0050] Specific, the upper and lower sides of the tool rest 3 are both installed with connecting plates, one side of the slide 203 is provided with an outwardly protruding protruding plate, a guide rod parallel to the Z-axis direction is arranged on the protruding plate, and the protruding plate is located between the two connecting plates; a knurled screw is screwed on the upper connecting plate, the lower end of the knurled screw abuts on the protruding plate, a spring is arranged between the protruding plate and the lower connecting plate, the spring is sleeved on the guide rod, and the two ends of the spring are respectively connected with the protruding plate and the lower connecting plate; therefore, under the action of the knurled screw, the spring and the guide rod, the height of the tool rest 3 can be adjusted by rotating the knurled screw, so that the cutting knife 10 assembled can be fully utilized.

[0051] Working principle:

[0052] First, rotate the handle 13 to drive the screw rod 206, move the support plate 202 along the X-axis direction by using the nut 207, and complete the coordinate adjustment of the cutting knife 10 in the X-axis direction; then rotate the knob of the limiting assembly 208, so that the output end of the limiting assembly 208 extends by a certain length, which ensures that when the lengthened rod 209 abuts against the output end of the limiting assembly 208, the cutting knife 10 can complete cutting of the workpiece 9 without causing the accident of hitting the cutting knife; then the workpiece 9 is sleeved on the clamping part 409 of the tool rod 404; the machine is started through the mode of foot switch or button switch, the motor 405 is driven to work, the rotating shaft 402 is driven to rotate through the synchronous belt 408, and the workpiece 9 is driven to rotate synchronously; then manually move the slide 203 along the Y-axis direction to move close to the limiting assembly 208 until the workpiece 9 is completely cut off or the lengthened rod 209 abuts against the output end of the limiting assembly 208; release the slide 203, and the tension spring 12 will pull the slide 203 back to the safe position; in the process, the microscope 7 is used to monitor the cutting process of the cutting knife 10 cutting the workpiece 9, and the cutting process is displayed on the display screen 8, so that the operator can know the progress of the machining of the micro product.
