Description

Technical Field

[0001] This invention relates to the field of raw material measurement, and in particular to a loading and detection system and method for a CNC lathe. Background Technology

[0002] During the production process of the workpiece, it is necessary to measure whether the raw materials meet the production requirements of the workpiece. Measuring each raw material one by one during the production process is not only time-consuming but also affects the actual production. Furthermore, manual disassembly of parts can cause inaccurate positioning.

[0003] To this end, Chinese invention patent No. 202010666533.9 discloses a trapezoidal platform size detection device and detection method, including a measuring base plate on which a part to be measured is placed. The part to be measured is a trapezoidal platform. The angle formed by the intersection of the two hypotenuse extensions of the trapezoidal cross-section of the trapezoidal platform is a slope angle. A left and right sliding measuring plate is slidably disposed on the measuring base plate. An upper and lower sliding measuring plate is slidably disposed on the left and right sliding measuring plate. A right sliding measuring plate, a left sliding measuring plate and a middle main measuring plate are slidably disposed on the upper and lower sliding measuring plate. The right sliding measuring plate has a right auxiliary measuring head, the left measuring plate has a left auxiliary measuring head, and the middle main measuring plate has a middle main measuring head. The present invention calculates the length of the small end by measuring the length of the large end and the slope angle.

[0004] Through research on the above-mentioned trapezoidal table size detection device and detection method, it was found that it can only measure the length of the workpiece and cannot transport the workpiece to the next process. In addition, the device requires manual operation, which is inefficient.

[0005] Therefore, we urgently need to invent a detection device and system that requires less human intervention, is highly efficient, and can directly transfer workpieces to the next processing step. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a loading and inspection system and method for CNC lathes. By setting up a width detection mechanism and a length detection mechanism, the width and length of the raw materials can be measured, enabling batch inspection, improving efficiency, and avoiding the problem of inaccurate positioning in manual measurement. By setting up a flipping transport mechanism, a clamping mechanism, and a clamping transport mechanism, the raw materials can be automatically transferred to the next process, greatly reducing manual intervention, improving the safety of the device, reducing handling time, and improving efficiency.

[0007] The technical solution used in this invention is: a loading detection system and method for a CNC lathe, comprising: a width detection mechanism, a length detection mechanism, a flipping and transporting mechanism, a clamping mechanism, and a clamping and transporting mechanism; the width detection mechanism includes an upper horizontal plate and a vertical plate A, the upper horizontal plate and the vertical plate A being fixed perpendicularly to each other, a motor A being mounted on the protrusion of the vertical plate A, a gear on the motor A meshing with a tooth on a threaded sleeve A, a lead screw A being rotatably mounted inside the threaded sleeve A, a push plate A being fixed to the front end of the lead screw A, and two connecting rods A being slidably mounted on the vertical plate A, with springs fitted on the connecting rods A, one end of the springs... Fixed on the upright plate A, the control rod is connected to the end of the connecting rod A. The round part of the control rod is slidably mounted on the lower horizontal plate. The round part of the control rod passes through the through hole of the detection frame support block. The detection frame support block is connected to the lower horizontal plate by a spring. A detection frame is fixed above the detection frame support block. A recycling box is fixedly installed on the lower side of the lower horizontal plate. The front end of the upper horizontal plate is equipped with a length detection mechanism and a flipping transport mechanism. The lower horizontal plate is connected to a clamping mechanism. A clamping transport mechanism is installed in the middle of the clamping mechanism. The clamping mechanism and the clamping transport mechanism are located below the length detection mechanism and the flipping transport mechanism.

[0008] When this device is needed, the raw material first passes through the width detection mechanism. The position of the detection frame is adjusted by rotating the lead screw mounted at the bottom of the frame according to the diameter of the raw material. After the frame is adjusted, the raw material is placed on the upper horizontal plate. When the diameter of the raw material is small, it will directly press against the frame, which cannot support it. Under gravity, the material will fall into the recycling box. When the diameter meets the requirements, the frame supports the material. Then, motor A rotates, driving threaded sleeve A to rotate. Threaded sleeve A drives lead screw A to rotate, which in turn drives push plate A to push the raw material forward. When the raw material enters the length detection mechanism, it flips over. Push plate A then continues to push the material, allowing its length to be measured in the length detection mechanism. When the length is not met, the length detection mechanism will push the raw material back into the width detection mechanism. At this time, motor A drives push plate A to move backward, push plate A drives connecting rod A to move backward, connecting rod A drives control rod to move backward, and the protrusion on the control rod will cause the detection frame support block to move, thereby separating the detection frame. The raw material falls from the gap in the middle of the detection frame into the recycling box. Then push plate A moves forward a certain distance, and under the action of the spring, the control rod will return to its original position, which in turn causes the detection frame to return to its original position. When the length is met, the flipping and conveying mechanism starts, flipping the raw material. The raw material moves from the length detection mechanism to the clamping mechanism, and then the clamping mechanism moves the raw material to the corresponding position. Finally, the clamping and conveying mechanism clamps and transports the raw material to a position that the lathe can reach.

[0009] Furthermore, the inclined block in the length detection mechanism is fixed on the upper horizontal plate, making the inclined block higher than the upper horizontal plate. When the raw material comes into contact with the inclined block, the raw material will be rotated 90° under the push of the push plate A, and then change from vertical placement to horizontal placement.

[0010] Furthermore, the length detection mechanism includes: an inclined block, a top plate A, a clamping rod, a vertical plate B, and a clamping block base; the inclined block is fixedly installed in the middle of the upper horizontal plate, and its end is perpendicularly fixed to the vertical plate B; a clamping rod is slidably installed on the vertical plate B, and a spring is sleeved on the clamping rod, with the end of the spring fixed to the vertical plate B; one end of the clamping rod is fixed to the top plate A; the clamping block base is slidably installed in an elliptical groove in the upper horizontal plate; when the length of the raw material needs to be measured, the position of the clamping block base is adjusted by sliding it according to the required length of the raw material. After adjustment, the length is measured by screw... The wire secures the base of the clamping block. When the raw material moves into the length detection mechanism, the front end of the raw material contacts the top plate A. The raw material continues to move forward, causing the top plate A to move, which in turn moves the clamping rod. When the length of the raw material is long enough, the clamping rod moves to the designated position and is fixed by the clamping block base. The push plate A moves back to its original position, and the raw material is placed on the inclined block. When the length of the raw material is not long enough, the raw material pushes the top plate A to move, and the clamping rod cannot move to the position of the clamping block base. When the push plate A moves back, the top plate A moves back under the action of the spring, which then moves the raw material to the width detection mechanism.

[0011] Furthermore, the tilting and conveying mechanism includes: a baffle, a round rod, a lower pressure block, an inclined lower pressure block, a fixed bracket, and a gear; a round rod is slidably mounted on the vertical plate B, passing through through holes in the lower pressure block and the fixed bracket; the inclined lower pressure block is positioned below the lower pressure block, and is connected to the upper horizontal plate via a spring; a rack on the inclined lower pressure block meshes with a gear, which is fixed to the shaft of the baffle, and the shaft of the baffle is rotatably mounted on the upper horizontal plate; the position of the round rod is adjusted according to the length of the raw material, and after adjustment, it is... The screw connects the round rod to the lower pressure block. After the push plate A places the raw material on the inclined block, the raw material pushes the top plate A to move, which in turn moves the round rod, which in turn moves the lower pressure block, causing the inclined lower pressure block to press down. This causes the rack to press down, which in turn drives the gear to rotate, which in turn causes the baffle to flip. As a result, the raw material slides down the baffle onto the clamping mechanism under the action of gravity. After the top plate A is manually reset, the inclined lower pressure block, the lower pressure block and the round rod return to their original positions under the action of the spring, and then the baffle returns to its original position under the action of the spring.

[0012] Furthermore, a coil spring is provided in the gap between the threaded sleeve C and the vertical plate C in the clamping mechanism. When the control gear is pressed, the rotary knob controls the threaded sleeve C to rotate, which in turn drives the lead screw to move, and then drives the top plate B to move to the designated position.

[0013] Furthermore, the locking block on the lower side of the clamp fixing block cooperates with the rack. When the clamp fixing block moves forward, the rack will fix the clamp fixing block, preventing the clamp fixing block from moving backward under the action of the spring.

[0014] Because the present invention adopts the above-described technical solution, the present invention has the following advantages:

[0015] (1) By setting up a width detection mechanism and a length detection mechanism, the width and length of the raw materials can be measured, realizing batch detection, improving efficiency, and avoiding the problem of inaccurate positioning in manual measurement;

[0016] (2) By setting up a flipping transport mechanism, a clamping mechanism and a clamping transport mechanism, the raw materials can be automatically transferred to the next process, which greatly reduces the human involvement, improves the safety of the device, reduces the handling time and improves efficiency.

Detailed Implementation

[0027] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention; however, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Examples, such as Figure 1-9 As shown, a loading and inspection system and method for a CNC lathe include: a width detection mechanism 1, a length detection mechanism 2, a flipping and transporting mechanism 3, a clamping mechanism 4, and a clamping and transporting mechanism 5.

[0029] The width detection mechanism 1 includes an upper horizontal plate 101 and a vertical plate A102, which are fixed perpendicularly to each other. A motor A103 is mounted on the protrusion of the vertical plate A102. The gear on the motor A103 meshes with the gear on the threaded sleeve A104. A lead screw A105 is rotatably mounted inside the threaded sleeve A104. A push plate A106 is fixed to the front end of the lead screw A105. Two connecting rods A107 are slidably mounted on the vertical plate A102. Springs are fitted onto the connecting rods A107, one end of which is fixed to the vertical plate A102. The end of the connecting rods A107 is connected to a control rod 108. The control rod 108... The round rod part is slidably mounted on the lower horizontal plate 109. The round rod part of the control rod 108 passes through the through hole of the detection frame support block 110. The detection frame support block 110 is connected to the lower horizontal plate 109 by a spring. The detection frame 111 is fixed above the detection frame support block 110. The recycling box 112 is fixedly mounted on the lower side of the lower horizontal plate 109. The front end of the upper horizontal plate 101 is equipped with a length detection mechanism 2 and a flipping transport mechanism 3. The lower horizontal plate 109 is connected to the clamping mechanism 4. The clamping transport mechanism 5 is installed in the middle of the clamping mechanism 4. The clamping mechanism 4 and the clamping transport mechanism 5 are located below the length detection mechanism 2 and the flipping transport mechanism 3.

[0030] When this device is needed, the raw material first passes through the width detection mechanism 1. The position of the detection frame 111 is adjusted by rotating the lead screw mounted on the lower part of the detection frame 111 according to the diameter of the raw material. After the position of the detection frame 111 is adjusted, the raw material is placed on the upper horizontal plate 101. When the diameter of the raw material is small, it will directly press against the detection frame 111, which cannot support it. Under the influence of gravity, the raw material will fall into the recycling box 112. When the diameter meets the requirements, the detection frame 111... 1. The raw material is supported on top, then the motor A103 rotates, driving the threaded sleeve A104 to rotate. The threaded sleeve A104 drives the lead screw A105 to rotate, thereby driving the push plate A106 to push the raw material forward. When the raw material enters the length detection mechanism 2, because the inclined block 201 in the length detection mechanism 2 is fixed on the upper horizontal plate 101, the inclined block 201 is higher than the upper horizontal plate 101. When the raw material contacts the inclined block 201, the raw material will be rotated 90° under the push of the push plate A106, and then... The material is changed from a vertical to a horizontal position. Then, pusher plate A106 continues to push the material, allowing its length to be measured in length detection mechanism 2. If the length is insufficient, length detection mechanism 2 will push the material back into width detection mechanism 1. At this time, motor A103 drives pusher plate A106 to move backward, pusher plate A106 drives connecting rod A107 to move backward, connecting rod A107 drives control rod 108 to move backward, and the protrusion on control rod 108 will cause the detection frame support block 110 to move, thereby causing the detection frame 111 to... As the material leaves, it falls from the gap in the middle of the detection frame 111 into the recycling box 112. Then, the push plate A106 moves forward a certain distance, and under the action of the spring, the control rod 108 returns to its original position, which in turn causes the detection frame 111 to return to its original position. When the length is sufficient, the flipping transport mechanism 3 is activated, flipping the material. The material moves from the length detection mechanism 2 into the clamping mechanism 4, which then moves the material to the corresponding position. Finally, the clamping transport mechanism 5 clamps and transports the material to a position that the lathe can reach.

[0031] Examples, such as Figure 3As shown, the length detection mechanism 2 includes: an inclined block 201, a top plate A202, a locking rod 203, a vertical plate B204, and a locking block base 205. The inclined block 201 is fixedly installed in the middle of the upper horizontal plate 101, and the end of the inclined block 201 is vertically fixed to the vertical plate B204. The locking rod 203 is slidably installed on the vertical plate B204, and a spring is sleeved on the locking rod 203. The end of the spring is fixed to the vertical plate B204, and one end of the locking rod 203 is fixed to the top plate A202. The locking block base 205 is slidably installed in the elliptical groove of the upper horizontal plate 101. When the length of the raw material needs to be measured, the position of the locking block base 205 is adjusted by sliding the locking block base 205 according to the required length of the raw material. The base 205 is fixed with screws. When the raw material moves into the length detection mechanism, the front end of the raw material contacts the top plate A202. The raw material continues to move forward, driving the top plate A202 to move, which in turn drives the clamping rod 203 to move. When the length of the raw material is long enough, the clamping rod 203 moves to the designated position and is fixed by the base 205. The push plate A106 moves back to its original position, and the raw material is placed on the inclined block 201. When the length of the raw material is not long enough, the raw material pushes the top plate A202 to move, and the clamping rod 203 cannot move to the position of the base 205. When the push plate A106 moves back, the top plate A202 moves back under the action of the spring, which then moves the raw material to the width detection mechanism 1.

[0032] Examples, such as Figure 3-4 As shown, the tilting and conveying mechanism 3 includes: a baffle 301, a round rod 302, a lower pressing block 303, an inclined lower pressing block 304, a fixed bracket 305, and a gear 306; the round rod 302 is slidably mounted on the vertical plate B204, passing through through holes in the lower pressing block 303 and the fixed bracket 305; the inclined lower pressing block 304 is located below the lower pressing block 303, and is connected to the upper horizontal plate 101 by a spring; the rack on the inclined lower pressing block 304 meshes with the gear 306, and the gear 306 is fixed on the shaft of the baffle 301, which is rotatably mounted on the upper horizontal plate 101; the position of the round rod 302 is adjusted according to the length of the raw material. After alignment, the round rod 302 is connected to the lower pressure block 303 with screws. After the push plate A106 places the raw material on the inclined block 201, the raw material pushes the top plate A202 to move, which in turn moves the round rod 302, which in turn moves the lower pressure block 303, thereby causing the inclined lower pressure block 304 to press down, which in turn causes the rack to press down, which in turn causes the gear 306 to rotate, which in turn causes the baffle 301 to flip, so that the raw material slides down onto the clamping mechanism 4 under the action of gravity through the baffle 301. After manually resetting the top plate A202, the inclined lower pressure block 304, the lower pressure block 303 and the round rod 302 return to their original positions under the action of the spring, and then the baffle 301 returns to its original position under the action of the spring.

[0033] Examples, such as Figure 5-7As shown, the clamping mechanism 4 includes: a motor B401, a support plate 402, a lower clamping baffle 403, a threaded sleeve B404, a lead screw B405, a push plate B406, a vertical plate C407, a threaded sleeve C408, a knob 409, a lead screw C410, a top plate B411, a control gear 412, a control sleeve 413, a lead screw D414, a mounting bracket B415, a clamp fixing block 416, a clamp 417, and a coil spring 418; the support plate 402 is fixedly connected to the lower horizontal plate 109, and the lower clamping baffle 403 is fixed on the upper side of the support plate 402. The motor B401 is fixed at the front end of the lower clamping baffle 403, and the gear on the motor B401 and the threaded sleeve B404 meshes with the threaded sleeve B404, which is fixed on the bracket on the clamping lower baffle 403. The lead screw B405 is rotatably installed inside the threaded sleeve B404. The front end of the threaded sleeve B404 is fixedly connected to the push plate B406. A vertical plate C407 is vertically installed at the end of the support plate 402. A threaded sleeve C408 is rotatably installed on the vertical plate C407. A coil spring 418 is installed in the gap between the threaded sleeve C408 and the vertical plate C407. The threaded sleeve C408 is fixedly connected to the knob 409. A lead screw C410 is slidably installed inside the threaded sleeve C408. The lead screw C410 is fixedly connected to the top plate B411. The teeth of the threaded sleeve C408 mesh with the control... The control gear 412 meshes with the control sleeve 413. A lead screw D414 is slidably mounted inside the control sleeve 413. One end of the lead screw D414 is fixedly connected to the mounting bracket B415, which is slidably mounted on the vertical plate C407. A spring is provided between the control sleeve 413 and the mounting bracket B415. The lead screw D414 and the lower half of the clamp fixing block 416 are on the same horizontal line. Two clamps 417 are mounted on the top of the clamp fixing block 416. When the coil spring 418 in the gap between the threaded sleeve C408 and the vertical plate C407 is in a contracted state, the control gear 412 is pressed down, and the knob 409 is rotated. Then, the threaded sleeve C408 rotates, which in turn drives the lead screw C410 to move, and then drives the top plate B411 to move to the designated position. When the material slides onto the clamping lower baffle 403, the motor B401 drives the lead screw B405 to move, which in turn drives the push plate B406 to move. The push plate B406 drives the material to move, which in turn drives the top plate B411 to move, thereby driving the lead screw C410 to move, which in turn drives the threaded sleeve C408 to rotate, which in turn drives the control gear 412 to rotate, which in turn drives the control sleeve 413 to rotate, which in turn drives the lead screw D414 to move, thereby pushing the clamp fixing block 416 to move, and then moving the clamp 417 to the designated position.

[0034] Examples, such as Figure 8-9As shown, the clamping and transporting mechanism 5 includes: a rotary cylinder 501, a connecting block 502, a connecting rod B 503, a connecting plate 504, a base 505, an arc-shaped block 506, a manual turntable 507, a lead screw E 508, a motor C 509, a rack 510, and a bracket 511; the rotary cylinder 501 is fixed to the top of the clamp fixing block 416, the clamp fixing block 416 slides in the groove at the end of the connecting plate 504, the side of the clamp fixing block 416 is connected to the connecting plate 504 by a spring, and the groove at the end of the connecting plate 504... It is also equipped with a rack 510 and a bracket 511. A connecting block 502 passes through the middle of the bracket 511. The connecting block 502 is connected to the connecting plate 504 by a spring. The other end of the connecting plate 504 is connected to the shaft of the motor C509. The motor C509 is fixed inside the arc-shaped block 506. The arc-shaped block 506 is fixed on the base 505. The base 505 is slidably installed in the groove of the support plate 402. A lead screw E508 is also slidably installed on the base 505. One end of the lead screw E508 is equipped with a manual turntable 507.

[0035] When clamp 417 moves to the designated position, rotary cylinder 501 drives clamp 417 to rotate, thereby clamping the material. Motor C509 rotates, causing connecting plate 504 to flip, which in turn causes clamp 417 to flip at a certain angle, allowing the material to flip to the middle position of the lathe clamp. After clamp 417 flips, arc block 506 pushes connecting rod B503 to move, which in turn moves connecting block 502, thereby controlling rack 510 to move down, causing rack 510 to disengage from clamp fixing block 416. Under the action of spring, clamp fixing block 416 is reset, thereby moving the material to a certain position. The lathe clamp holds the material, rotary cylinder 501 drives clamp 417 to open, and clamp 417 is reset under the drive of motor C509. Pressing control gear 412, under the action of coil spring 418 and spring, top plate B411 and lead screw C410 return to their original positions.

The clamping block base (205) is slidably installed in the elliptical groove of the upper horizontal plate (101); when the length of the raw material needs to be measured, the clamping block base (205) is slidably adjusted according to the length of the raw material. After setting and adjusting, the clamp base (205) is fixed with screws. When the raw material moves into the length detection mechanism, the front end of the raw material contacts the top plate A (202). The raw material continues to move forward, driving the top plate A (202) to move, thereby driving the clamp rod (203) to move. When the length of the raw material is long enough, the clamp rod (203) moves to the designated position and is fixed by the clamp base (205). The push plate A (106) moves back to its original position, and the raw material is placed on the inclined block (201). When the length of the raw material is not long enough, the raw material pushes the top plate A (202) to move. The clamp rod (203) cannot move to the position of the clamp base (205). When the push plate A (106) moves back, the top plate A (202) moves back under the action of the spring, and then the raw material moves to the width detection mechanism (1).

2. The material loading and detection system for a CNC lathe according to claim 1, characterized in that, A coil spring (418) is provided in the gap between the threaded sleeve C (408) and the vertical plate C (407) in the clamping mechanism (4). When the control gear (412) is pressed, the rotary knob (409) controls the threaded sleeve C (408) to rotate, which in turn drives the lead screw C (410) to move, and then drives the top plate B (411) to move to the designated position.

3. The material loading and detection system for a CNC lathe according to claim 1, characterized in that, The locking block on the lower side of the clamp fixing block (416) cooperates with the rack (510). When the clamp fixing block (416) moves forward, the rack (510) will fix the clamp fixing block (416) to prevent the clamp fixing block (416) from moving backward under the action of the spring.
