Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, specifically a grinding equipment for precision casting gates. Background Technology

[0002] In the production process of precision castings, a gating system must be designed in order to inject molten metal into the mold cavity, and the gate is the main channel connecting the casting and the gating system. After the casting is formed, these gates must be removed and further processed to obtain a finished product with accurate dimensions and a smooth surface.

[0003] However, most existing grinding equipment uses a fixed stroke or manually adjustable clamping method. When dealing with precision castings of varying widths and sizes, operators need to stop the machine and manually adjust or even replace the clamps. This adjustment process is cumbersome and time-consuming, causing frequent equipment interruptions and severely slowing down the pace of continuous production. More importantly, after grinding, the release action of the traditional clamping mechanism often lacks coordination with the unloading station, failing to create the best opportunity and space for automated unloading, causing waiting or interference in the unloading process, further reducing overall efficiency.

[0004] The vast majority of production sites still rely on manual loading and unloading by operators. This is not only a repetitive and heavy physical labor that leads to worker fatigue, but also the operation speed of personnel fluctuates and is difficult to match perfectly with the stable rhythm of automated grinding machines, becoming a bottleneck to improving overall production capacity. In addition, the high intensity of manual involvement also brings higher labor and management costs.

[0005] For the finishing process of gate grinding, precise control of grinding depth is crucial. Existing equipment often uses fixed limiting methods such as mechanical stops or relies on the operator's feel for adjustment, which cannot achieve real-time and precise control during the grinding process. This can easily lead to insufficient grinding, gate residue, and unqualified products; or excessive grinding, which can damage the casting body, cause scrap, and affect the consistency of processing results and product yield.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figures 5-10 As shown, the precision casting gate grinding device of the present invention includes a grinding machine 1, a grinding assembly 2 disposed on the grinding machine 1, and a clamping assembly 4 disposed on the grinding assembly 2;

[0037] The grinding assembly 2 includes a collecting hopper 201, a connecting shaft 207, an indexing plate 208, and an annular track 209. The collecting hopper 201 is fixedly connected to the grinding machine 1. The connecting shaft 207 is rotatably connected to the collecting hopper 201. The indexing plate 208 is fixedly connected to the connecting shaft 207. The annular track 209 is fixedly connected inside the collecting hopper 201. The indexing plate 208 is rotatably connected to the annular track 209. The indexing plate 208 is provided with a clamping assembly 4.

[0038] The clamping assembly 4 includes a base 401 and a baffle 402. Multiple sets of bases 401 are fixedly connected to the indexing plate 208. A baffle 402 is fixedly connected between two bases 401 in each set. A first clamping plate 405 is slidably connected to the base 401. A sliding plate 407 is slidably connected inside the base 401. The sliding plate 407 has a sloping groove 408, and the base 401 has a flat groove 409. A roller 410 is rotatably connected to the bottom end of the first clamping plate 405. The roller 410 is tumbledly connected to the sloping groove 408 and the flat groove 409. A connecting rod 411 is fixedly connected to the sliding plate 407, and two connecting rods 411 are fixedly connected together. A connecting bar 413 is fixedly connected to the two connecting rods 411. A driving block 412 with a semi-circular cross-section is slidably connected to the ends of the two connecting rods 411. A first screw 414 is rotatably connected to the driving block 412 and threadedly connected to the connecting bar 413. A stop block 416 with a semi-circular cross-section is fixedly connected to the annular track 209. A first washer 406 is fixedly connected to the first clamping plate 405. A spring 415 is fixedly connected between the connecting bar 413 and the indexing plate 208. Two sliders 404 with T-shaped cross-sections are fixedly connected to the bottom end of the first clamping plate 405. Two sliding grooves 404 with T-shaped cross-sections are provided on the base 401. 3. The slider 404 is slidably connected to the groove 403; the indexing plate 208 rotates intermittently under the drive system; when the clamping station containing the casting leaves the loading area and enters the grinding area, the driving block 412 at its bottom will contact the abutment block 416 with a semi-circular cross section fixedly installed on the annular track 209. As the indexing plate 208 continues to rotate, the abutment block 416 presses against the driving block 412, forcing the driving block 412 to slide towards the connecting bar 413. The driving block 412 pushes the first screw 414. Since the first screw 414 and the connecting bar 413 are threadedly connected, and the connecting bar 413 is supported by the spring 415... Compression causes the connecting bar 413 to move toward the center of the indexing plate 208. The connecting bar 413 drives the two slide plates 407 to slide inward synchronously inside the base 401 through the two connecting rods 411. The inclined groove 408 on the slide plate 407 moves accordingly. The roller 410 at the bottom of the first clamping plate 405 was originally located at the intersection of the inclined groove 408 and the flat groove 409. It rolls under the action of the inclined surface of the inclined groove 408. Since the roller 410 is installed on the first clamping plate 405, and the first clamping plate 405 is restricted to the base 401 through the cooperation of the T-shaped slider 404 and the T-shaped groove 403, it can only slide horizontally.Therefore, the force of the inclined groove 408 forces the first clamping plate 405 to move stably towards the casting, and finally clamps the casting firmly through the first shim 406. When grinding is completed, the drive block 412 and the abutment block 416 disengage. At this time, the compressed spring 415 releases its elastic force, pushing the connecting bar 413 to move in the opposite direction, thereby driving the slide plate 407 to reset. The inclined groove 408 on the slide plate 407 moves in the opposite direction, and the roller 410 slides back to its initial position along the inclined surface. The first clamping plate 405 then releases its grip on the casting, preparing for the unloading assembly 6 to grab the casting. When it is necessary to adjust the clamping stroke of the first clamping plate 405 according to the size of the casting, the extension length of the connecting rod 411 on the drive block 412 can be adjusted by rotating the first screw 414 on the drive block 412, thereby adjusting the initial position of the slide plate 407. The initial position of the slide plate 407 changes, and the initial position of the first clamping plate 405 changes accordingly, thus adapting to clamping castings of different widths.

[0039] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figures 5-7 and Figure 9 As shown, a first fixed sleeve 205 is fixedly connected to the bottom end of the collecting hopper 201. A first drive shaft 206 is rotatably connected to the first fixed sleeve 205. The first drive shaft 206 is fixedly connected to the connecting shaft 207. A second pulley 204 is fixedly connected to the bottom end of the first drive shaft 206. A first drive component 202 is fixedly connected to the grinding machine 1. A first pulley 203 is fixedly connected to the output end of the first drive component 202. The first pulley 203 and the second pulley 204 are driven by a belt. A fixed seat 212 is provided on the grinding machine 1 to fix... A second fixed sleeve 213 is fixedly connected to the base 212. A second drive shaft 214 is rotatably connected to the second fixed sleeve 213. A fourth pulley 215 is fixedly connected to the top end of the second drive shaft 214. A second drive component 210 is fixedly connected to the grinding machine 1. A third pulley 211 is fixedly connected to the output shaft of the second drive component 210. The third pulley 211 and the fourth pulley 215 are driven by a belt. An installation plate 216 is installed on the second drive shaft 214 through an adjustment component 3. A grinding disc 217 is installed on the installation plate 216.

[0040] Adjustment assembly 3 includes a connecting rod 301 and a lifting shaft 302. A hexagonal prism connecting rod 301 is fixedly connected to the second transmission shaft 214. The lifting shaft 302 is slidably connected to the connecting rod 301. Two limiting discs 303 are fixedly connected to the lifting shaft 302. A bearing 304 and a lifting plate 305 are installed between the two limiting discs 303. The lifting shaft 302 is rotatably connected to the bearing 304, and the lifting plate 305 is rotatably connected to the bearing 304. A mounting plate 216 is fixedly connected to the bottom end of the lifting shaft 302. A fixed base 212 is fixedly connected to... Two third drive components 306 are provided, with their telescopic ends fixedly connected to the lifting plate 305. A second drive component 210 (preferably a motor) is activated, driving a fourth pulley 215 to rotate at high speed via a third pulley 211 and a belt. The fourth pulley 215 drives a second transmission shaft 214 to rotate within a second fixed sleeve 213, thereby transmitting power to the entire grinding disc 217. The third drive component 306 (usually a cylinder or servo electric cylinder) is activated, its telescopic end pushing or pulling the lifting plate 305. The lifting plate 305 is connected via bearings... 304 is connected to the lifting shaft 302, allowing the lifting shaft 302 to rotate freely relative to the lifting plate 305 and be driven by it to perform vertical linear motion. The lifting shaft 302 drives the grinding disc 217 to rise and fall together via the mounting plate 216 at its bottom, precisely adjusting the grinding depth. The hexagonal prism structure of the connecting rod 301 ensures that the lifting shaft 302 can always rotate synchronously with the second transmission shaft 214 while sliding up and down, transmitting torque. Under the control of the third drive component 306, the high-speed rotating grinding disc 217 descends to the predetermined position, grinding the already... The clamped casting gate is ground; the grinding debris is collected by the collection hopper 201 below. The first drive unit 202 (preferably a motor) drives the first drive shaft 206 to rotate through the transmission of the first pulley 203, the belt and the second pulley 204. The first drive shaft 206 drives the indexing plate 208 to rotate intermittently on the circular track 209 through the connecting shaft 207. Each rotation is a fixed angle, which moves an empty station to the loading position, moves the loaded station to the grinding position, and moves the ground station to the unloading position, thus realizing the cycle operation.

[0041] Specifically, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 10As shown, a feeding assembly 5 is placed on one side of the collection hopper 201. The feeding assembly 5 includes a first conveyor belt 501 and a mounting frame 502. The first conveyor belt 501 is placed on one side of the collection hopper 201, and two mounting frames 502 are fixedly connected to the first conveyor belt 501. A pusher 503 is slidably connected between the two mounting frames 502. A second screw 504 is rotatably connected to one of the mounting frames 502. A fourth drive component 505 is fixedly connected to the mounting frame 502. The output end of the fourth drive component 505 is connected to the first screw 504. Two screws 504 are fixedly connected. Two L-shaped support bars 506 are fixedly connected to the push bar 503. Mounting plates 507 are fixedly connected to the two support bars 506. A fifth driving component 508 is fixedly connected to the mounting plate 507. A push plate 509 is fixedly connected to the telescopic end of the fifth driving component 508. Two slide rails 510 are fixedly connected to the push bar 503. Two sliding sleeves 511 are fixedly connected to the push plate 509. The sliding sleeves 511 are slidably connected to the slide rails 510. The operator places multiple grinding plates into the slide. The precision castings are neatly arranged on the first conveyor belt 501. The first conveyor belt 501 starts, conveying the castings forward in batches until the foremost casting reaches the preset "loading preparation position". The fourth drive unit 505 (usually a servo motor or stepper motor) starts, driving the second screw 504 to rotate. The pusher 503, which is threaded with the second screw 504, slides laterally along the two mounting brackets 502, so that the mounting plate 507 and the pusher plate 509 on it are precisely moved to the pushing position behind the casting. The telescopic end of the fifth drive component 508 (usually a cylinder or electric push rod) extends, pushing the push plate 509 forward. The push plate 509 moves smoothly along the slide rail 510, pushing the casting located in the "loading preparation position" into the indexing plate 208 between the two bases 401 at the loading station, and making it close to the baffle 402 to complete the initial positioning. After completion, the fifth drive component 508 retracts, and the fourth drive component 505 rotates in the opposite direction, causing the push bar 503 to return to the initial position, preparing for the next loading cycle.

[0042] A feeding assembly 6 is placed on one side of the collecting hopper 201. The feeding assembly 6 includes a second conveyor belt 601 and a fixing frame 602. The second conveyor belt 601 is placed on one side of the collecting hopper 201. Two fixing frames 602 are fixedly connected to the second conveyor belt 601. Fixing plates 603 are fixedly connected to the two fixing frames 602. A sixth driving member 604 is fixedly connected to the fixing plate 603. A slide 605 is fixedly connected to the telescopic end of the sixth driving member 604. The slide 605 is slidably connected to the fixing frame 602. A third screw 606 is rotatably connected to the slide 605. Two second clamping plates 607 are symmetrically threaded onto the third screw 606, with opposite thread directions at both ends. Second washers 608 are fixedly connected to the second clamping plates 607. A seventh driving component 610 is fixedly connected to the slide 605, with its output end fixedly connected to the third screw 606. A guide shaft 609 is fixedly connected to the slide 605, and the second clamping plates 607 are slidably connected to the guide shaft 609. A guide rod 611 is fixedly connected to the fixed frame 602, and the slide 605 is slidably connected to the guide rod 611. The sixth driving component 604 (usually a cylinder or electric push rod) is activated, its telescopic end extends, and it pushes the slide 605 along the guide rod 611 towards the casting that has been released from its clamping position on the indexing plate 208. When the slide 605 moves directly above the casting, the seventh driving component 610 (usually a motor) is activated, driving the third screw 606 to rotate. Because the threads at both ends of the third screw 606 are in opposite directions, and... Two second clamping plates 607 are slidably connected to the guide shaft 609. They move synchronously towards each other and firmly clamp the casting through the second shim 608. The sixth drive member 604 retracts and pulls the slide 605, which has clamped the casting, back to above the second conveyor belt 601. The seventh drive member 610 rotates in the opposite direction and drives the two second clamping plates 607 to move in opposite directions, releasing the finished casting onto the second conveyor belt 601. The second conveyor belt 601 starts and transports the finished product away from the working area, completing the entire processing cycle.

[0043] In use, the operator first neatly places multiple precision castings with gates to be ground onto the first conveyor belt 501. The first conveyor belt 501 is started, conveying the castings forward in batches until the foremost casting reaches the preset "feeding preparation position". The fourth drive unit 505 (usually a servo motor or stepper motor) is started, driving the second screw 504 to rotate. The pusher 503, which is threaded with the second screw 504, slides laterally along the two mounting brackets 502, so that the mounting plate 507 and the pusher plate 509 on it move precisely. When the casting reaches the push position behind it, the telescopic end of the fifth drive component 508 (usually a cylinder or electric push rod) extends, pushing the push plate 509 forward. The push plate 509 moves smoothly along the slide rail 510, pushing the casting located in the "loading preparation position" into the indexing plate 208 between the two bases 401 at the loading station, and making it close to the baffle 402 to complete the initial positioning. After completion, the fifth drive component 508 retracts, and the fourth drive component 505 rotates in the opposite direction, causing the push bar 503 to return to the initial position, preparing for the next loading cycle.

[0044] Then, the indexing plate 208 rotates intermittently under the drive system; when the clamping station containing the casting leaves the loading area and enters the grinding area, the drive block 412 at its bottom contacts the abutment block 416 with a semi-circular cross-section, which is fixedly installed on the annular track 209. As the indexing plate 208 continues to rotate, the abutment block 416 presses against the drive block 412, forcing the drive block 412 to slide towards the connecting bar 413. The drive block 412 pushes the first screw 414. Since the first screw 414 and the connecting bar 413 are threadedly connected, and The connecting bar 413 is compressed by the spring 415. This thrust will push the connecting bar 413 towards the center of the indexing plate 208. The connecting bar 413 drives the two slide plates 407 to slide synchronously inward inside the base 401 through the two connecting rods 411. The inclined groove 408 on the slide plate 407 moves accordingly. The roller 410 at the bottom of the first clamping plate 405 was originally located at the intersection of the inclined groove 408 and the flat groove 409. It rolls under the action of the inclined surface of the inclined groove 408. Since the roller 410 is installed on the first clamping plate 405, and the first clamping plate 408 is located at the intersection of the inclined groove 408 and the flat groove 409, it rolls. 5. The T-shaped slider 404 is confined to the base 401 by the cooperation of the T-shaped groove 403, and can only slide horizontally. Therefore, the force of the inclined groove 408 forces the first clamping plate 405 to move stably towards the casting, and finally the casting is firmly clamped by the first washer 406. When the grinding is completed, the drive block 412 and the abutment block 416 disengage. At this time, the spring 415, which has been compressed, releases its elastic force, pushes the connecting bar 413 to move in the opposite direction, and then drives the slide plate 407 to reset. The inclined groove 408 on the slide plate 407 moves in the opposite direction, and the roller... 410 slides back to its initial position along the inclined plane, and the first clamping plate 405 releases its grip on the casting, preparing for the unloading assembly 6 to grab the casting. When it is necessary to adjust the clamping stroke of the first clamping plate 405 according to the size of the casting, the extension length of the connecting rod 411 on the drive block 412 can be adjusted by rotating the first screw 414 on the drive block 412, thereby adjusting the initial position of the slide plate 407. When the initial position of the slide plate 407 changes, the initial position of the first clamping plate 405 changes accordingly, thus adapting to clamping castings of different widths.

[0045] Finally, the second drive unit 210 (preferably a motor) starts, driving the fourth pulley 215 to rotate at high speed via the third pulley 211 and the belt. The fourth pulley 215 drives the second transmission shaft 214 to rotate within the second fixed sleeve 213, thereby transmitting power to the entire grinding disc 217. The third drive unit 306 (usually a cylinder or servo electric cylinder) starts, its telescopic end pushing or pulling the lifting plate 305. The lifting plate 305 is connected to the lifting shaft 302 via the bearing 304, allowing the lifting shaft 302 to rotate freely relative to the lifting plate 305 and be driven to perform vertical linear motion. The lifting shaft 302 drives the grinding disc 217 to rise and fall together via the mounting plate 216 at its bottom, precisely adjusting the grinding depth; the hexagonal prism structure of the connecting rod 301 ensures... While the lifting shaft 302 slides up and down, it can always rotate synchronously with the second drive shaft 214 to transmit torque. Under the control of the third drive component 306, the high-speed rotating grinding disc 217 descends to the predetermined position to grind the clamped casting gate. The grinding debris is collected by the collection hopper 201 below. The first drive component 202 (preferably a motor) drives the first drive shaft 206 to rotate through the transmission of the first pulley 203, belt and second pulley 204. The first drive shaft 206 drives the indexing disc 208 to rotate intermittently on the circular track 209 through the connecting shaft 207. Each rotation is a fixed angle, turning an empty station to the loading position, turning the loaded station to the grinding position, and turning the ground station to the unloading position to realize the cycle operation.

[0046] The sixth drive unit 604 (usually a cylinder or electric push rod) is activated, and its telescopic end extends, pushing the carriage 605 along the guide rod 611 towards the casting that has been released from clamping on the indexing plate 208. When the carriage 605 moves directly above the casting, the seventh drive unit 610 (usually a motor) is activated, driving the third screw 606 to rotate. Since the threads at both ends of the third screw 606 are opposite in direction, and the two second clamping plates 607 are slidably connected to the guide shaft 609, they will move synchronously towards each other, firmly clamping the casting through the second washer 608. The sixth drive unit 604 retracts, pulling the carriage 605 that has clamped the casting back to above the second conveyor belt 601. The seventh drive unit 610 rotates in the opposite direction, driving the two second clamping plates 607 to move in opposite directions, releasing the finished casting onto the second conveyor belt 601. The second conveyor belt 601 is activated, transporting the finished product away from the working area, completing the entire processing cycle.
