Description

Technical Field

[0001] This invention relates to the field of grinding technology, specifically to a machining positioning mechanism for a rod-shaped shaft grinding lathe. Background Technology

[0002] Rod-shaped shafts are mainly used to transmit torque, support rotating parts, and provide precise positioning references. A good positioning system can isolate machine tool vibrations, absorb some cutting forces, and make the grinding process smooth. Ultimately, the combination of the high-precision motion trajectory of the grinding wheel and the stable positioning reference of the workpiece is necessary to "reproduce" extremely high shape and position accuracy on rod-shaped shafts with insufficient rigidity.

[0003] In related technologies, operators typically need to move the rod-shaped shaft between the cutting and grinding equipment, which requires repositioning and clamping before each grinding operation. This leads to a longer processing cycle and reduced processing efficiency. Summary of the Invention

[0015] Working principle: The rod-shaped shaft is poured into the feeding assembly. After the rod-shaped shaft falls to the appropriate position, the cross slide controls the slider to move. At this time, the first electric push rod is activated to drive the feeding mechanism to slide up and down. Multiple sets of grippers installed on the lower surface of the feeding mechanism hold the rod-shaped shaft, so that the cross slide controls the first electric push rod and the feeding mechanism to enter the feed port of the chuck. The feeding mechanism will control the rod-shaped shaft to enter the inner wall of the chuck. At this time, the chuck will hold the rod-shaped shaft and rotate. The second electric push rod will reciprocate to push and pull the reciprocating block and the cutting tool will reciprocate to slide and cut the rod-shaped shaft. At this time, the receiving assembly is controlled to receive the rod-shaped shaft.

[0016] This invention provides a machining positioning mechanism for a rod-shaped shaft grinding lathe. It has the following advantages: 1. This invention places the rod-shaped shaft onto the unloading assembly, while the cross slide controls the first electric push rod and the feeding mechanism to move synchronously. This allows the feeding mechanism to clamp the rod-shaped shaft into the chuck, where the second electric push rod pushes and pulls the reciprocating block and the cutting tool for cutting. The receiving assembly transports the rod-shaped shaft to the storage box, where it is then ground by the processing box. The positioning assembly positions the rod-shaped shaft, enabling continuous and automated grinding while simultaneously positioning it. This shortens processing time and improves processing efficiency.

[0017] 2. In this invention, the fourth electric push rod pushes and pulls the connecting block while simultaneously causing the rotating block to slide synchronously. This causes the rotating block to rotate the connecting rod while simultaneously causing the baffle and adjusting plate to rotate synchronously. When the rod-shaped shaft contacts the telescopic plate and the baffle through the inclined surface of the storage box, the telescopic plate can limit the baffle and prevent the subsequent rod-shaped shaft from entering, thus achieving a stable material feeding effect for processing.

[0018] 3. The present invention drives the swing rod to rotate through the telescopic plate, so that the swing rod, together with the guide rod and the fixed block, pushes and pulls the fixed plate and the first rack to slide, so that the first rack drives the first clamping block and the second clamping block to fit against the rod-shaped shaft through the gear, which can achieve the effect of stabilizing the rod-shaped shaft for grinding.

[0019] 4. In this invention, the second clamping block pulls the third rack to slide, causing the third rack to drive the tooth column to rotate, which in turn drives the inclined plate to rotate, thereby allowing the inclined plate to unload the processed rod-shaped shaft through the opening and closing plate.

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1: Please refer to the appendix. Figure 1 - Appendix Figure 3 This invention provides a machining positioning mechanism for a rod-shaped shaft grinding lathe, including a bottom 1 and a protective shell 2. A chuck 10, a storage box 11, and a machining box 15 are fixed on the upper surface of the bottom 1. A cross slide 3 is fixed on the outer wall of the protective shell 2. A first electric push rod 4 is fixed on the slider part of the cross slide 3. A feeding mechanism 5 is fixed on the output end of the first electric push rod 4. A unloading component 9 is provided on the upper surface of the bottom 1. A second electric push rod 6 is fixed on the outer wall of the protective shell 2. A reciprocating block 7 is fixed on the output end of the second electric push rod 6. A cutting tool 8 is detachably installed on the upper surface of the reciprocating block 7. The lower inner wall of the reciprocating block 7 slides on the upper outer wall of the bottom 1. A receiving component 13 is provided on the inner wall of the storage box 11.

[0024] Specifically, multiple sets of rod-shaped shafts are poured into the unloading assembly 9 installed on the upper surface of the bottom 1. The unloading assembly 9 will feed the rod-shaped shafts one by one. After the rod-shaped shafts fall into the appropriate position, the cross slide 3 installed on the outer wall of the protective shell 2 will control the slider on the cross slide 3 to move. At this time, the first electric push rod 4 is activated to drive the feeding mechanism 5 to slide up and down. The feeding mechanism 5 has multiple sets of grippers installed on its lower surface to hold the rod-shaped shafts, so that the cross slide 3 controls the first electric push rod 4 and the feeding mechanism 5 to enter the feed port of the chuck 10. When the feeding mechanism 5 moves to the appropriate position, the electrically controlled push rod installed on the inner wall of the feeding mechanism 5 will push the rod-shaped shaft into the inner wall of the chuck 10. At this time, the chuck 10 will clamp the rod-shaped shaft and rotate. The chuck 10 is existing technology and will not be described in detail here. When the chuck 10 clamps the rod-shaped shaft and rotates, the second electric push rod 6 installed on the outer wall of the protective shell 2 will push and pull the reciprocating block 7 back and forth. The upper surface of the reciprocating block 7 is detachably equipped with a cutting tool 8. By changing the cutting tool 8, different types of rod-shaped shafts can be cut. When the reciprocating block 7 and the cutting tool 8 reciprocate to cut the rod-shaped shaft, the cross slide 3 will control the first electric push rod 4 and the feeding mechanism 5 to reset synchronously. At this time, the receiving component 13 on the inner wall of the storage box 11 is controlled to move, so that the receiving component 13 can receive the rod-shaped shaft. After the chuck 10 and the cutting tool 8 finish machining the rod-shaped shaft, the chuck 10 will push the rod-shaped shaft out and let it fall onto the receiving component 13. At this time, the receiving component 13 will retract, allowing the machined rod-shaped shaft to enter the inclined surface of the storage box 11, so that the rod-shaped shaft enters the groove at the lower part of the inclined surface of the storage box 11. The positioning component 12 will position the rod-shaped shaft and allow it to enter the machining box 15 for grinding, which can achieve the effect of continuous positioning grinding of the rod-shaped shaft.

[0025] Please see the appendix Figure 2 and attached Figure 3 The feeding assembly 9 includes a support base 91, the lower surface of which is fixed to the upper surface of the bottom 1. An adjusting block 92 slides on the inner wall of the support base 91. The outer walls on both sides of the support base 91 are fixed to the inner wall of the protective shell 2. An adjusting rod 93 is provided on the inner wall of the adjusting block 92. A third electric push rod 94 is fixed on the upper surface of the bottom 1. A push-pull block 95 is fixed on the output end of the third electric push rod 94. One outer wall of the push-pull block 95 slides on the outer wall of the support base 91. A feeding block 96 slides on the other outer wall of the push-pull block 95. The lower surface of the feeding block 96 is fixed to the upper surface of the bottom 1.

[0026] Specifically, when the rod-shaped shaft is placed on the adjusting block 92, the adjusting rod 93 is first adjusted to control the adjusting blocks 92 on both sides to slide synchronously on the inner wall of the support base 91, which can achieve the effect of adapting to rod-shaped shafts of different lengths. There are two sets of adjusting rods 93; one set of adjusting rods 93 is fixed on the inner wall of one side of the adjusting block 92, while the other set of adjusting rods 93 rotates on the inner wall of the other side of the adjusting block 92 and is connected. Moreover, the two sets of adjusting rods 93 are connected by threads. At this time, rotating the other set of adjusting rods 93 can make the adjusting rod 93 and the adjusting block 92 move synchronously. After adjusting the adjusting block 92 to a suitable spacing, insert the rod-shaped shaft. Since the support base 91 is inclined, the rod-shaped shaft slides along the outer wall of the push-pull block 95. When feeding is required, start the third electric push rod 94 to pull the push-pull block 95 down to a certain position and then push the push-pull block 95. This allows the push-pull block 95 to achieve a stable feeding effect. Moreover, the push-pull block 95 can block the multiple sets of rod-shaped shafts inside the adjusting block 92 to prevent them from falling off. After the push-pull block 95 feeds the material, the rod-shaped shaft will move to the bottom of the feeding mechanism 5 through the unloading block 96, which facilitates continuous feeding of the rod-shaped shaft.

[0027] Please see the appendix Figure 3 and attached Figure 4 The receiving assembly 13 includes a sixth electric push rod 1301. The outer wall of the sixth electric push rod 1301 is fixed to the inner wall of the storage box 11. A right-angle plate 1302 is fixedly provided at the output end of the sixth electric push rod 1301. The outer wall of the right-angle plate 1302 slides on the inner wall of the storage box 11. An inclined block 1303 slides on the upper outer wall of the right-angle plate 1302. One side of the outer wall of the inclined block 1303 is fixed to the inner wall of the storage box 11. A guide post 1304 is fixed on the upper surface of the right-angle plate 1302. A receiving plate 1305 slides on the outer wall of the guide post 1304. The lower outer wall of the receiving plate 1305 slides on the inclined surface of the inclined block 1303. The lower surface of the receiving plate 1305 slides on the upper surface of the right-angle plate 1302. The outer wall of the receiving plate 1305 slides on the inner wall of the storage box 11.

[0028] Specifically, when the cross slide 3 feeds material, the receiving plate 1305 is in the reset state. When the cross slide 3 resets, the sixth electric push rod 1301 pushes the right-angle plate 1302 to slide, causing the right-angle plate 1302 to slide synchronously with the receiving plate 1305 via the guide post 1304. Since the right-angle plate 1302 slides on the lower surface of the inclined block 1303, it can achieve stable sliding and prevent displacement. When the right-angle plate 1302 drives the receiving plate 1305 to slide, due to the inclined block... The contact surface between 1303 and receiving plate 1305 is inclined, which allows receiving plate 1305 to be stably lifted during sliding. After receiving plate 1305 catches the rod-shaped shaft, when the sixth electric push rod 1301 pulls the right-angle plate 1302, receiving plate 1305 will contact right-angle plate 1302 through guide post 1304, which allows receiving plate 1305 to vibrate during material feeding, so that receiving plate 1305 can stably feed material to the inclined surface of storage box 11.

[0029] Example 2: Please refer to the appendix. Figure 3 - Appendix Figure 6 The inner wall of the storage box 11 is provided with a positioning component 12, which includes a baffle plate 1201. The outer wall of the baffle plate 1201 is fixed to the inner wall of the storage box 11. A connecting rod 1202 is rotatably connected to the lower inner wall of the baffle plate 1201. A baffle plate 1207 and an adjusting plate 1208 are respectively fixed to the outer wall of the connecting rod 1202. A telescopic plate 1209 slides on the inner wall of the adjusting plate 1208. The inclined outer walls of the baffle plate 1207 and the telescopic plate 1209 slide on the inclined outer wall of the storage box 11. An elastic element 1210 is fixed between the inner wall of the adjusting plate 1208 and the outer wall of the telescopic plate 1209. A fixed column 1203 is fixed to the outer wall of the storage box 11. A fourth electric push rod 1204 is rotatably mounted on the outer wall of the fixed column 1203. A connecting block 1205 is fixedly mounted on the output end of the fourth electric push rod 1204. A rotating block 1206 is rotatably mounted on the outer wall of the connecting block 1205. The inner wall of the rotating block 1206 is fixed to the outer wall of the connecting rod 1202. The outer wall of the connecting rod 1202 rotates on the inner wall of the storage box 11. A fifth electric push rod 1211 is fixed to the inner wall of the storage box 11. A top block 1212 is fixedly mounted on the output end of the fifth electric push rod 1211. The outer wall of the top block 1212 slides on the concave outer wall of the storage box 11.

[0030] Specifically, when the rod-shaped shaft passes through the inclined surface of the storage box 11, the feeding speed of the rod-shaped shaft, in conjunction with the inclined surface of the telescopic plate 1209, causes the rod-shaped shaft to push the telescopic plate 1209 to slide to the inner wall of the adjusting plate 1208 and compress the elastic element 1210. After the rod-shaped shaft contacts the baffle 1207, it will stop moving. Since the adjusting plate 1208 and the baffle 1207 are at an angle and fixed to the outer wall of the connecting rod 1202, after the elastic element 1210 pushes the telescopic plate 1209 to reset, the telescopic plate 1209 will lock the rod-shaped shaft with the baffle 1207, which can achieve the effect of rapid positioning. Moreover, the telescopic plate 1209 can resist the subsequent rod-shaped shaft, which can achieve the effect of stable feeding. When grinding the rod-shaped shaft, the fourth electric push rod 1204 is activated, pulling the connecting block 1205 to slide while simultaneously causing the rotating block 1206 to rotate. The rotating block 1206 then causes the connecting rod 1202 to rotate against the inner wall of the baffle plate 1201, ensuring stable rotation of the connecting rod 1202. When the connecting rod 1202 drives the baffle 1207 and the telescopic plate 1209 to rotate, the baffle 1207 disengages from the inclined surface of the storage box 11, allowing the rod-shaped shaft to be fed. The elastic element 1210 will push the telescopic plate 1209 to always be in contact with the inclined surface of the storage box 11. At this time, the telescopic plate 1209 will push the rod-shaped shaft to feed. When the telescopic plate 1209 rotates to the appropriate position, the telescopic plate 1209 will contact the limiting component 14, so that the limiting component 14 squeezes the telescopic plate 1209 and the elastic element 1210, thereby making the telescopic plate 1209 and the adjusting plate 1208 rigidly connected, which can achieve the effect of stabilizing and preventing the subsequent rod-shaped shaft from entering. When the fourth electric push rod 1204 pushes the connecting block 1205 to rotate the rotating block 1206 and the connecting rod 1202, the elastic element 1210 will push the telescopic plate 1209 to slide, which at the same time facilitates the subsequent rod-shaped shaft to be locked again by the telescopic plate 1209 and the baffle 1207, thus achieving the limiting effect. When the rod-shaped shaft enters the groove of the storage box 11, the fifth electric push rod 1211 is activated to push the top block 1212 to slide, so that the top block 1212 pushes the rod-shaped shaft into the processing box 15 for grinding.

[0031] Please see the appendix Figure 4 Appendix Figure 7 Appendix Figure 8 and attached Figure 9The inner wall of the storage box 11 is provided with a limiting component 14, which includes a swing rod 1401. The outer wall of the swing rod 1401 rotates on the inner wall of the storage box 11, and the upper outer wall of the swing rod 1401 slides on the outer wall of the telescopic plate 1209. The outer wall of the swing rod 1401 is rotatably connected to an elastic telescopic rod 1402, which rotates on the inner wall of the storage box 11. The lower inner wall of the swing rod 1401 is rotatably connected to a guide rod 1403. A fixing block 1404 slides on the inner wall of the storage box 11. A fixing plate 1405 is fixed to the outer wall of the fixing block 1404. A limiting plate 1406 is attached to the outer wall of the fixing plate 1405. The outer wall of the limiting plate 1406 slides on the inner wall of the storage box 11. A first clamping block 1407 and a second clamping block 1408 slide on the inner wall of the storage box 11 respectively. The lower surfaces of the first clamping block 1407 and the second clamping block 1408 are respectively fixed to the upper surface of the limiting plate 1406. The inner wall of the first clamping block 1407 slides... On the outer wall of the swing arm 1401, a second rack 1411 is fixed to the outer wall of the limiting plate 1406 below the first clamping block 1407, and a first rack 1409 slides on the inner wall of the limiting plate 1406. One side of the outer wall of the first rack 1409 is fixed to the outer wall of the fixing plate 1405, and the outer wall of the limiting plate 1406 below the second clamping block 1408 is fixed to the other side of the outer wall of the first rack 1409. The outer walls of the first rack 1409 and the second rack 1411 slide on the storage box respectively. On the inner wall of storage box 11, the teeth of the first rack 1409 and the second rack 1411 mesh with a gear 1410. The outer wall of the gear 1410 rotates on the inner wall of storage box 11. The outer wall of the second clamping block 1408 is fixed with a third rack 1412. The teeth of the third rack 1412 mesh with a toothed column 1413. The outer wall of the toothed column 1413 rotates on the inner wall of storage box 11. An inclined plate 1414 is fixed on the outer wall of the toothed column 1413. An opening and closing plate 1415 rotates on the inner wall of storage box 11.

[0032] Specifically, when the baffle 1207 allows the rod-shaped shaft to enter the groove of the storage box 11, the lower outer wall of the inclined plate 1414 will abut against the rod-shaped shaft. At this time, the fifth electric push rod 1211, in conjunction with the top block 1212, pushes the rod-shaped shaft into the processing box 15, achieving a limiting effect on the rod-shaped shaft. Furthermore, the telescopic plate 1209 will push the swing rod 1401 to rotate, and the swing rod 1401 will pull the guide rod 1403 and squeeze the elastic telescopic rod 1402. Simultaneously, the guide rod 1403 pulls the fixed block 1404 and pulls the first rack 1409 and the fixed plate 1405 to slide synchronously, thereby allowing the first rack 1409 to drive the second rack 1411 to slide through the gear 1410. The second rack 1411 and the first rack 1409 can pull the limiting plate 1406 to center synchronously. The limiting plate 1406 drives the first clamping block 1407 and the second clamping block 1408 to center and position the rod shaft. When the first clamping block 1407 and the second clamping block 1408 contact the rod shaft, the swing rod 1401 will not be able to move. The tilt angle of the swing rod 1401 will make the telescopic plate 1209 and the adjusting plate 1208 form a rigid connection. When the first clamping block 1407 and the second clamping block 1408 position the rod shaft, the swing rod 1401 will form a rigid connection with the telescopic plate 1209 and the adjusting plate 1208, so as to achieve a stable positioning effect of the rod shaft. When the second clamping block 1408 slides in the center, it will drive the third rack 1412 to slide synchronously. At this time, the third rack 1412 will drive the tooth end of the tooth column 1413 to rotate, thereby causing the tooth column 1413 to drive the inclined plate 1414 to rotate and retract. When the telescopic plate 1209 resets and disengages from the swing rod 1401, the elastic telescopic rod 1402 will push the swing rod 1401 to reset. At the same time, the swing rod 1401 can limit the first clamping block 1407. The reset of the swing rod 1401 will drive the guide rod 1403 to slide on the outer wall of the fixed block 1404 and push the fixed plate 1405 to slide, thereby causing the second clamping block 1408 to drive the third rack 1412 to slide synchronously. At this time, the third rack 1412 drives the tooth column 1413 to rotate and simultaneously drives the inclined plate 1414 to rotate synchronously, causing the inclined plate 1414 to lift the rod-shaped shaft, allowing the rod-shaped shaft to roll and the opening and closing plate 1415 to open for unloading, thus achieving the effect of continuous processing.

[0033] Please see the appendix Figure 1 and attached Figure 10 A push-pull rod 16 is fixed to the inner wall of the processing box 15. An adjustment mechanism 19 is provided on the inner wall of the processing box 15. A rotating rod 18 rotates on the inner wall of the adjustment mechanism 19. A grinding wheel 17 is provided on the outer wall of the rotating rod 18.

[0034] Specifically, when the rod-shaped shaft enters the processing box 15 and abuts against the output end of the push-pull rod 16, the adjusting mechanism 19 will slide in the center, so that the rotating rod 18 and the grinding wheel 17 slide synchronously and fit against the rod-shaped shaft. At this time, the rotating rod 18 drives the grinding wheel 17 to rotate for grinding. After grinding is completed, the push-pull rod 16 is activated to push out the rod-shaped shaft, which can achieve a stable material output effect. Moreover, the adjusting mechanism 19 is a commonly used centering structure in existing grinding equipment, which will not be described in detail here.

[0035] The workflow is as follows: First, multiple sets of rod-shaped shafts are poured onto the adjusting block 92. Since the support base 91 is inclined, when the third electric push rod 94 drives the push-pull block 95 to slide back and forth, the rod-shaped shafts are pushed onto the unloading block 96 one by one. After the rod-shaped shafts fall to the designated position, the first electric push rod 4 is activated to drive the multiple sets of grippers on the lower surface of the feeding mechanism 5 to contact and clamp the rod-shaped shafts. At this time, the cross slide 3 drives the first electric push rod 4 and the feeding mechanism 5 to move, sending the clamped rod-shaped shafts into the feed port of the chuck 10 to complete the feeding and positioning. The second electric push rod 6 is activated to push and pull the reciprocating block 7 to slide, so that the reciprocating block 7 drives the cutting tool 8 to slide back and forth synchronously to cut the rotating rod-shaped shaft. When machining the rod-shaped shaft, the cross slide 3 is reset, and the sixth electric push rod 1301 will push the right angle plate 1302 to slide, so that the right angle plate 1302 drives the guide column 1304 and the receiving plate 1305 to slide synchronously, so that the receiving plate 1305 contacts the inclined block 1303, so that the receiving plate 1305 is stably lifted during the sliding process and adjusted to a suitable receiving height. When the receiving plate 1305 is retracted, it will pour the rod-shaped shaft onto the inclined surface of the storage box 11. The rod-shaped shaft slides along the inclined surface of the storage box 11, cooperating with the inclined surface of the telescopic plate 1209, pushing the telescopic plate 1209 to slide to the inner wall of the adjusting plate 1208 and compressing the elastic element 1210. The rod-shaped shaft stops moving after contacting the baffle 1207. The elastic element 1210 pushes the telescopic plate 1209 to reset. The telescopic plate 1209 and the baffle 1207 cooperate to hold the rod-shaped shaft, achieving rapid positioning. At the same time, the telescopic plate 1209 abuts against the subsequent rod-shaped shaft, achieving a stable feeding effect. The fourth electric push rod 1204 is activated to cooperate with the connecting block 1205 and The rotating block 1206 moves, causing the connecting rod 1202 to drive the baffle 1207 and the telescopic plate 1209 to rotate synchronously. After the telescopic plate 1209 rotates to the appropriate position, it will rotate with the swing rod 1401. At this time, the swing rod 1401 pulls the guide rod 1403 and squeezes the elastic telescopic rod 1402, so that the fixed block 1404 drives the first rack 1409 and the gear 1410 to rotate through the fixed plate 1405, thereby allowing the first clamping block 1407 and the second clamping block 1408 to be synchronously aligned and attached to the rod-shaped shaft, which can achieve the effect of positioning the rod-shaped shaft. The rod-shaped shaft enters the processing box 15 and abuts against the output end of the push-pull rod 16. At this time, the adjustment mechanism 19 is activated and slides in the center, driving the rotating rod 18 and the grinding wheel 17 to slide synchronously, so that the grinding wheel 17 is in contact with the surface of the rod-shaped shaft for grinding.
