Description

Technical Field

[0001] The present invention relates to the technical field of tool detection, and its name is a tool detection device for automatic continuous detection of cutting tools. Background Art

[0002] Cutting tools are tools used for cutting in machining. The scope of cutting tools is relatively wide, such as tools for machining various outer surfaces, hole machining tools, thread machining tools, cutting tools, etc. Among them, there are many rod-shaped tools, such as drills and end mills, etc. The overall shape is cylindrical. Generally, for this type of tool, its coaxiality needs to be ensured to guarantee the cutting accuracy.

[0003] In the existing patent application No. 201610942200.8, "Tool Detection Device and Detection Method" is disclosed, which includes: a base; a tool holder rotatably connected to the base; a tool shank for clamping the tool to be detected, and the tool shank is detachably arranged on the tool holder; a dial indicator arranged on the base for detecting the coaxiality of the tool fixed on the tool holder. In the above tool detection device, a dial indicator and a rotatable tool holder are arranged on the base. When the tool holder rotates, the deflection of the pointer of the dial indicator can be accurately observed from the dial indicator, so as to quickly judge whether the clamped tool meets the standard.

[0004] However, the above technical solutions only focus on how to detect a tool once. During continuous operation, the staff needs to continuously install the tool shank and the tool. After the detection is completed, it also needs to be manually removed. The work efficiency and automation degree are relatively low, and it can only be applied to single-time and small-batch tool detection, and cannot continuously detect the tool body.

[0005] Therefore, it is necessary to provide a tool detection device for automatic continuous detection of cutting tools, which can achieve the function of automatic continuous detection. Summary of the Invention

Of course, they are only examples and are not intended to limit the present application.

[0042] Please refer to Figure 1-7 , the present invention provides a technical solution: a tool detection device for automatic continuous detection of a cutting tool, including a feeding section 2, a material clamping section 3, a pushing section 4, a locking section, a detection section, and a feeding section 6; wherein:

[0043] The feeding section 2 includes a discharging rack 201, and a plurality of tool bodies 7 are stacked inside the discharging rack 201. The feeding section 2 is used to sequentially feed a plurality of tool bodies 7 in the discharging rack 201 into the material clamping section 3;

[0044] The cartridge part 3 is used to receive a single tool body 7 and position it. The locking part and the pusher part 4 are respectively arranged at both ends of the cartridge part 3;

[0045] The pusher part 4 is used to push the tool body 7 in the cartridge part 3 into the locking part;

[0046] The locking part includes a first locking mechanism and a second locking mechanism. The two locking mechanisms lock and fix the tool body 7. The detection part is arranged on the upper side of the locking part;

[0047] The detection part is arranged on the lifting mechanism. The detection part includes a rotating mechanism and a dial indicator 5. The lifting mechanism drives the detection part to move up and down. When the rotating mechanism contacts the locking part and the dial indicator 5 contacts the tool body 7, the coaxiality of the tool body 7 is detected by the dial indicator 5 while the tool body 7 rotates;

[0048] The feeding part 6 automatically transports the detected tool body 7 to the subsequent process.

[0049] Specifically, the staff first stacks a number of tool bodies 7 to be detected in the discharging rack 201. The tool bodies 7 stacked in the discharging rack 201 are sequentially fed into the cartridge part 3 through the feeding part 2. The cartridge part 3 positions and supports a single tool body 7. Then, the tool body 7 is pushed from the cartridge part 3 into the locking part by the pusher part 4. The locking part is provided with two locking mechanisms to fix the tool body 7. Since two locking mechanisms are provided, two fixing points appear on the tool body 7, further ensuring the axial accuracy of the fixed tool. After fixing, the lifting mechanism drives the detection part to descend, so that the rotating mechanism contacts the locking part and drives the locking part to drive the tool body 7 to rotate, while the dial indicator 5 contacts the tool body 7, so that the dial indicator 5 detects the coaxiality of the rotating tool body 7. The staff can judge whether the coaxiality of the tool body 7 to be detected is qualified according to the deflection of the pointer of the dial indicator 5. The deflection includes the number of deflections and the deflection amplitude. Then, the unqualified products are removed by the staff, and the qualified tool bodies 7 are sent to the subsequent process by the feeding part 6, thus completing the continuous automatic detection of the tool body 7. There is no need for manual feeding and fixing of the tool, greatly improving the work efficiency and being applicable to the detection work of a large number of tools.

[0050] The first locking mechanism includes a rotating ring 101. A support base 1 is rotatably connected to the lower side of the rotating ring 101. The lower end of the support base 1 is fixedly connected to a fixed platform 702. A number of fixed guide rods 102 are fixedly connected to the inner side of the rotating ring 101. A pair of clamping plates 103 are arranged on the middle side of the fixed guide rods 102. The pair of clamping plates 103 clamp the tool body 7 by approaching each other. The fixed guide rods 102 penetrate through both ends of the pair of clamping plates 103 and are slidably matched with them. A first spring is arranged on the outer side of the fixed guide rods 102. Both ends of the first spring are respectively connected to the two clamping plates 103. A T-shaped key groove is formed in the inner side of the rotating ring 101. A pair of wedge blocks 104 are fixedly connected to the outer ends of the pair of clamping plates 103. The second locking mechanism is arranged on the support base 1 in the same way as the first locking mechanism;

[0051] A pair of wedge blocks 105 are oppositely arranged on the inclined surfaces of the wedge blocks 104. The inclined surfaces of the wedge blocks 104 and the wedge blocks 105 are oppositely arranged. An arc-shaped plate 106 is fixedly connected to the outer end of the wedge block 105. The outer side of the arc-shaped plate 106 is slidably matched with the rotating ring 101. A T-shaped key 107 is fixedly connected to the outer side of the arc-shaped plate 106. The T-shaped key 107 is slidably matched with the T-shaped key groove. A pair of push plates 108 are fixedly connected to the inner side of the wedge block 105.

[0052] Specifically, when the tool body 7 enters the two pairs of clamping plates 103 in the first locking mechanism and the second locking mechanism, it needs to be clamped. At this time, a pair of push plates 108 are pushed simultaneously. The push plates 108 push a pair of arc-shaped plates 106 to slide on the inner walls of the two rotating rings 101, and the T-shaped keys 107 slide in the T-shaped key grooves to guide the movement of the arc-shaped plates 106. Two pairs of wedge blocks 105 are fixedly connected to the inner side of the arc-shaped plates 106. The arc-shaped plates 106 drive the two pairs of wedge blocks 105 to move towards the wedge blocks 104 at the same time, so that the two pairs of wedge blocks 105 are in contact with the inclined surfaces of the two pairs of wedge blocks 104 and push the two pairs of wedge blocks 104 along their inclined surfaces, so as to push the clamping plates 103. Under the guiding action of the fixed guide rods 102, the two pairs of clamping plates 103 approach the tool body 7 until the tool body 7 is clamped, thus completing the fixation of the tool body 7. The fastening effect is good, and at the same time, the two pairs of clamping plates 103 clamp the tool body 7, so that when the tool body 7 is clamped and rotated, it can maintain good stability and axial accuracy, which is convenient for detection.

[0053] Since the clamping plates 103 are in the clamped state, the first spring is in a compressed state. When it is necessary to loosen the tool body 7, only the thrust on the push plates 108 needs to be cancelled. Under the reset action of the first spring, the two side clamping plates 103 are pushed to separate from each other on both sides, so that the wedge blocks 104 and the wedge blocks 105 return to their original positions, that is, the tool body 7 is loosened.

[0054] The material pushing part 4 includes a material pushing rod 401. One end of the material pushing rod 401 is penetrated with a gear box 405. The lower end of the gear box 405 is fixedly connected to a workbench 701. A straight groove is opened at the lower end of the material pushing rod 401. A rack 402 is arranged inside the straight groove. One end of the rack 402 is meshed with a first gear 403. A threaded rod 406 is fixedly connected to the middle side of the first gear 403. The threaded rod 406 is rotationally connected to the gear box 405. The threaded rod 406 is driven to rotate by a motor assembly. The diameter of the material pushing rod 401 is equal to the diameter of the tool body 7. A pressing disc 404 is rotationally connected to the material pushing end of the material pushing rod 401. The diameter of the pressing disc 404 is larger than the diameter of the tool body 7. While the pressing disc 404 pushes the tool body 7 into the locking mechanism, it also pushes a pair of push plates 108 to clamp them.

[0055] Specifically, the tool body 7 is pushed into the locking mechanism by the material pushing rod 401. First, the motor assembly drives the threaded rod 406 to rotate. The threaded rod 406 drives the first gear 403 to rotate. The first gear 403 is meshed with the rack 402, thereby pushing the material pushing rod 401 to move, and the tool body 7 can be pushed into the locking mechanism. At the same time, at one end of the material pushing rod 401 in contact with the tool body 7, a pressing disc 404 is rotationally connected. When the pressing disc 404 pushes the tool body 7 into the locking mechanism, when the tool body 7 completely enters the locking mechanism, at this time the pressing disc 404 also contacts the push plate 108 (as Figure 4 shown), and pushes it. At this time, the position of the tool body 7 also corresponds to the position of the dial indicator 5. At this time, the pressing disc 404 continues to push the push plate 108, thereby driving the clamping plate 103 to lock and fix the tool body 7. So that the material pushing rod 401 can push the tool body 7 into the locking mechanism while completing the fixation of the tool body 7, that is, only one motor assembly can realize the two functions of material pushing and fixing, saving costs, and having a high degree of automation. There is no need for manual feeding and clamping, improving work efficiency.

[0056] The card material part 3 includes a card material box 301. One end of the card material box 301 is fixedly connected to the support base 1, and the card material box 301 is fixedly connected to the gear box 405. A through port 302 is provided in a penetrating manner on a side surface of the card material box 301 close to the feeding part 2. A square through groove is provided on a side surface of the card material box 301 away from the feeding part 2. Two guide rods 303 are vertically arranged in the square through groove. A pair of moving strips 304 are arranged on the guide rods 303. The guide rods 303 penetrate through the moving strips 304 and are in sliding fit with them. A number of second springs are arranged on the outer sides of the guide rods 303. Two ends of the second springs are respectively connected to the card material box 301 and the moving strips 304. One end of the moving strip 304 is rotatably connected with two pairs of rotating rods 305. Two pairs of groove wheels 306 are rotatably connected to the outer sides of the two pairs of rotating rods 305. The two pairs of groove wheels 306 are used for clamping the tool body 7 and sending it into the locking mechanism. A circular ring part 307 is fixedly connected to a side surface of the two pairs of groove wheels 306 close to the feeding part 2. The outer ring of the circular ring part 307 is provided with an inclined chamfer. The feeding part 2 sends the tool body 7 into the two pairs of groove wheels 306 along the inclined chamfer. The pushing rod 401 pushes one end of the tool body 7 and guides it into the locking mechanism along with the rolling of the groove wheels 306.

[0057] Specifically, when the tool body 7 is in the groove wheel 306, the pushing rod 401 pushes the tool body 7, so that the tool body 7 moves along the groove wheel 306. The groove wheel 306 rolls and guides the tool body 7 into the locking mechanism. When the tool body 7 needs to be placed in the groove wheel 306, the feeding part 2 pushes the tool body 7 placed horizontally towards the middle side of the two pairs of groove wheels 306 and first contacts the circular ring part 307. Since the outer side of the circular ring part 307 is provided with an inclined chamfer, the cylindrical surface of the tool body 7 contacts the inclined surface. With the continuous pushing of the feeding part 2, the tool body 7 pushes the two circular ring parts 307 on both sides upwards and downwards, so that the groove wheels 306 and the moving strips 304 both move towards both sides and are guided along the guide rods 303. The second springs are compressed until the tool body 7 enters the inner side of the groove wheel 306. Under the reset action of the second springs, the groove wheels 306 return to their original positions, thereby clamping the tool body 7 in the middle, positioning and supporting it, and facilitating the accurate pushing of the pushing rod 401.

[0058] A pair of concave strips 202 are fixedly connected to the lower end of the blanking rack 201. One end of each concave strip 202 is fixedly connected to both ends of the material clamping box 301. The inner groove of the concave strip 202 is located in the middle of two pairs of groove wheels 306. The other end of the concave strip 202 is fixedly connected to a fixing plate 203. The lower end of the fixing plate 203 is fixedly connected to the workbench 701. A slope through opening 204 is formed in the upper end of the concave strip 202. The slope through opening 204 is arranged at the lower end of the blanking rack 201. The inner groove of the concave strip 202 is in clearance fit with the tool body 7. The tool bodies 7 stacked in the blanking rack 201 fall into the inner groove of the concave strip 202 through the slope through opening 204. A pair of pushing plates 205 are slidably fitted in the inner side of the concave strip 202. The pushing plates 205 are completely sunk into the inner groove of the concave strip 202 and are slidably fitted with it. The two pushing plates 205 are connected by a connecting plate 206. The pushing plates 205 penetrate through the fixing plate 203 and are slidably fitted with it. One side of the connecting plate 206 is provided with a first telescopic rod 207, and the first telescopic rod 207 is connected to the fixing plate 203. A plurality of semi-circular ring members 208 are fixedly connected to the other side of the connecting plate 206. The semi-circular ring members 208 are used to push the tool body 7 and move it along the inner groove of the concave strip 202 to the middle position between the two pairs of groove wheels 306. The connecting plate 206 is driven to move by a linear driving assembly.

[0059] Specifically, the staff stacks a number of tool bodies 7 to be detected in the blanking rack 201 in advance. Under the action of gravity, the tool bodies 7 will fall downward and pass through the slope through opening 204 and fall into the inner groove of the concave strip 202. Due to the clearance fit between the groove and the tool body 7, the lateral ends of the tool body 7 just slide along the groove. And the tool bodies 7 still in the blanking rack 201 will fall into the slope through opening 204 and be supported by the tool bodies 7 below. There is a pushing plate 205 sliding in the concave strip 202, and the pushing plate 205 is completely sunk into the groove. The connecting plate 206 and the semi-circular ring members 208 are driven by the linear driving assembly, so as to drive the two pushing plates 205 to move in the groove. The semi-circular ring members 208 push the tool body 7 in the groove to the middle position between the two pairs of groove wheels 306. The two ends of the tool body 7 in the slope through opening 204 will rest on the pushing plates 205 to prevent it from falling. After the tool body 7 is pushed into the groove wheel 306 for positioning, the connecting plate 206 and the pushing plate 205 are reset, and the upper tool body 7 will fall into the groove again, which is convenient for the next pushing, realizing the automatic continuous feeding of the tool body 7 and improving the work efficiency.

[0060] A moving plate 209 is fixedly connected to the lower end of the connecting plate 206. A threaded rod 406 penetrates through the moving plate 209 and is threadedly connected to it. One end of the threaded rod 406 is rotatably connected to the fixing plate 203.

[0061] Specifically, when the threaded rod 406 rotates driven by the motor assembly, thereby driving the pushing rod 401 to push the tool body 7 in the groove wheel 306 into the locking mechanism, at this time, the threaded rod 406 is also threadedly connected to the moving plate 209, that is, the threaded rod 406 also drives the moving plate 209 to move along the threaded rod 406 at the same time. The moving plate 209 is connected to the connecting plate 206, that is, it realizes that the threaded rod 406 drives the pushing rod 401 and the connecting plate 206 to move at the same time. The effect achieved is that when the pushing rod 401 pushes the tool body 7 into the locking mechanism, the connecting plate 206 is reset, and the tool body 7 in the discharging rack 201 falls into the groove and waits to be pushed. Then, the threaded rod 406 and the first gear 403 are reversed, so that the pushing rod 401 returns to its original position. At this time, the connecting plate 206 will push the tool body 7 in the groove into the material clamping part 3, so as to automatically feed the material. Then, the threaded rod 406 and the first gear 403 are rotated forward, the pushing rod 401 pushes the tool body 7 in the material clamping part 3 again, and the connecting plate 206 continues to return to its original position, and the work is carried out alternately and repeatedly. The synchronization is good, the two mechanisms operate alternately and orderly, and only a single motor assembly is used, saving costs.

[0062] The lifting mechanism includes a U-shaped frame 501. The U-shaped frame 501 is fixed on the fixed table 702. A pair of vertical rods 502 are fixedly connected to the inner side of the U-shaped frame 501. The lower ends of the vertical rods 502 are fixedly connected to the fixed table 702. A motor seat 503 is slidably fitted inside the U-shaped frame 501. The vertical rods 502 penetrate through the motor seat 503 and are slidably fitted with it. A cylinder 504 is arranged at the upper end of the motor seat 503. The rotating mechanism includes a motor 505. One end of the motor seat 503 is fixedly connected to the motor 505. One end of the motor 505 is provided with a transmission shaft 506. One end of the transmission shaft 506 is fixedly connected to a rubber roller 507. The lower side of the rubber roller 507 is correspondingly arranged with the rotating ring 101. The dial indicator 5 is fixed to the other end of the motor seat 503. The distance between the rubber roller 507 and the rotating ring 101 is equal to the distance between the dial indicator 5 and the tool body 7 to be detected.

[0063] Specifically, after the tool body 7 is fixed by the locking mechanism, the cylinder 504 is used to push the motor base 503 downward. The motor base 503 is guided along the vertical rod 502, so that the rubber roller 507 contacts the rotating ring 101. The motor 505 drives the rubber roller 507 to rotate, driving the rotating ring 101 to rotate, and then driving the fixed tool body 7 to rotate. Since the feeding rod 401 is rotatably connected to the pressing disc 404, when the pressing disc 404 presses the pushing plate 108, it can rotate with the rotating ring 101 without affecting the locking effect. At the same time, the motor base 503 also drives the dial indicator 5 downward, so that the probe of the dial indicator 5 contacts the surface of the tool body 7. As the tool body 7 rotates, the dial indicator 5 detects the coaxiality of the rotating tool body 7. The staff can judge whether the coaxiality of the tool body 7 to be detected is qualified according to the deflection of the pointer of the dial indicator 5. When the detection is completed, only the cylinder 504 is used to drive the motor base 503, the rubber roller 507 and the dial indicator 5 to reset, the rotating ring 101 stops rotating and the dial indicator 5 is separated from the tool body 7.

[0064] The feeding part 6 includes two pairs of feeding wheels 601. The two pairs of feeding wheels 601 are both fixed on the fixed table 702. The two pairs of feeding wheels 601 are connected to each other through a belt transmission mechanism. One pair of feeding wheels 601 is arranged on one side of the locking mechanism. The feeding wheels 601 are used to transmit and feed the detected tool body 7 into the conveyor belt assembly 602. The conveyor belt assembly 602 is fixedly connected to the fixed table 702. A plurality of arc plates 603 are arranged on the upper side of the conveyor belt assembly 602. The arc plates 603 are used to pick up the tool body 7 and transport it.

[0065] Specifically, after the detection is completed, the locking mechanism releases the tool body 7. The unqualified products are taken down by the staff, and the qualified products are rolled into the conveyor belt mechanism by the two pairs of rotating feeding wheels 601. A belt pulley and a conveyor belt are arranged between the two pairs of feeding wheels 601 for transmission connection to ensure the synchronism of transmitting the tool body 7. A plurality of arc plates 603 are arranged on the conveyor belt mechanism to facilitate picking up the tool body 7.

[0066] A rotating rod 8 is rotatably connected to the upper end of the U-shaped frame 501. One end of the rotating rod 8 is fixedly connected with a rubber wheel 801. The lower side of the rubber wheel 801 is correspondingly arranged with the rubber roller 507. One side of the rotating rod 8 is fixedly connected with a pulley one 802. A pulley two 803 is arranged on one side of the pulley one 802. A semi-cross belt connection is arranged between the pulley one 802 and the pulley two 803. The lower end of the pulley two 803 is fixedly connected with a long rod 804. The lower end of the long rod 804 is rotatably connected to the fixed table 702. A gear two 805 is fixedly connected to the lower side of the long rod 804. A crown gear 806 is meshed and connected to one side of the gear two 805. One side of the crown gear 806 is fixedly connected with the feeding wheel 601.

[0067] Specifically, after the detected rubber roller 507 leaves the rotating ring 101, it continues to move upward, so as to contact the rubber wheel 801, thereby driving the rubber wheel 801 to rotate. The rubber wheel 801 drives the rotating rod 8 and the first pulley 802 to rotate. The first pulley 802 and the second pulley 803 are connected by a semi-crossed belt drive (the semi-crossed belt drive is an existing technology in the belt drive mechanism, so it will not be elaborated too much), thereby driving the second pulley 803, the long rod 804 and the second gear 805 to rotate. The second gear 805 is meshed with the crown gear 806 to drive the crown gear 806 to rotate. The crown gear 806 is connected to the feeding wheel 601, thereby driving the feeding wheel 601 to rotate and sending the tool body 7 into the belt drive mechanism. That is, by moving the rubber roller 507 up and down and contacting the rotating ring 101 and the rubber wheel 801 respectively, the locking mechanism is driven to rotate to detect the tool body 7 and the feeding wheel 601 is driven to rotate to feed the tool body 7. It is realized that one motor 505 can drive two mechanisms at the same time, and the operations of the two are carried out alternately, with high automation and cost-saving effect.
