Description

Technical Field

[0001] This invention belongs to the field of bicycle frame processing, specifically relating to a grinding device for the inner wall of a bicycle saddle connector tube. Background Technology

[0002] Bicycle saddle connectors are thin-walled precision tubing, and their inner walls must meet high-precision sliding fit requirements. Traditional manual grinding is inefficient and produces inconsistent quality. General steel pipe grinding equipment is prone to causing pipe deformation, water contamination and rust on the inner walls, and dust residue affects usability. To adapt to mass production, there is an urgent need to develop an automated, dedicated inner wall grinding device to achieve high-precision, non-destructive, and dust-free grinding.

[0003] Patent CN221210957U discloses a grinding device for the inner wall of bicycle saddle connector tubes, belonging to the field of bicycle frame processing technology. It includes a processing box, with a first electric push rod fixedly connected to the side of the processing box. This application utilizes a first electric push rod, a fixing block, a fixing plate, a fixing screw, a connector tube body, a rotating screw, a servo motor, a slider, a positioning rod, a second electric push rod, a fixing box, a rotating shaft, a rotating motor, and a grinding block. First, the servo motor drives the grinding block horizontally via the slider, thereby grinding multiple saddle connector tubes one by one. During the grinding of the saddle connector tubes, the worker can fix the connector tube body in advance with an unused fixing plate. Then, after the saddle connector tube grinding is completed, the fixing block no longer limits the fixing plate; only the fixing plate needs to be replaced, and the above operation is repeated, thus improving the grinding efficiency of the device.

[0004] The above-mentioned device also has the following problems: the bicycle saddle connector tube is an aluminum alloy tube, which is easy to deform and difficult to install on the bicycle after deformation. The above-mentioned device uses a screw to drive the fixing plate to move to clamp the tube body, which can easily cause the tube body to deform. Summary of the Invention

[0005] The purpose of this invention is to provide a grinding device for the inner wall of a bicycle saddle insert tube, in order to solve the problem that clamping the tube body by moving a fixing plate driven by a screw can easily cause the tube body to deform.

[0006] To achieve the above objectives, the present invention provides a grinding device for the inner wall of a bicycle saddle insert tube, comprising: a worktable, a lower clamping plate fixedly connected to the worktable, an upper clamping plate rotatably connected to the top of the two lower clamping plates via a torsion spring, a rubber block fixedly connected to the top of the lower clamping plates, an insert tube placed on the rubber block, a grinding mechanism provided on the top of the worktable, a cleaning mechanism provided on the top of the worktable, a cooling mechanism provided on the top of the worktable, and a collection mechanism provided inside the worktable; The grinding mechanism includes a fixed base, which is fixedly connected to the top of the worktable.

The top of the worktable is provided with a motor, the output end of which is fixedly connected to the reciprocating screw. The inner wall of the cleaning frame is fixedly connected with an elastic cleaning mesh. During the grinding process, the air pipe blows air into the support rod through the square hole and blows air into the inner wall of the bicycle saddle insert pipe, blowing away the remaining aluminum shavings on the inner wall. Most of the aluminum shavings will be adsorbed in the gaps of the cleaning mesh of the cleaning frame, preventing the aluminum shavings from being blown around and scratching the inner wall of the bicycle saddle insert pipe.

[0009] According to another advantageous design of the present invention, the cleaning mechanism includes a fixed base two, which is fixedly connected to the top of the workbench. A reciprocating screw two is rotatably connected to the front and rear inner walls of the fixed base two. A slider two is movably connected to the circumferential surface of the reciprocating screw two. A fixed rod is fixedly connected to the right side of the slider two. A support block is fixedly connected to the circumferential surface of the fixed rod. An arc-shaped groove is formed at the front of the circumferential surface of the fixed rod. A telescopic rod one is fixedly connected to the left side of the arc-shaped groove. A limiting rod two is slidably connected to the circumferential surface of the inner wall of the slider two. The front and rear ends of the limiting rod two are fixedly connected to the fixed base two.

[0010] According to another advantageous design of the present invention, the right side of the telescopic rod 1 contacts the support rod, the left side of the support rod is fixedly connected to an air pipe, the support rod has a square hole inside, the bottom of the support block is rotatably connected to a roller, the grinding wheel connecting rod drives the grinding wheel to move to the right, the grinding wheel connecting rod drives the rotating shaft, cleaning frame and top rod to move to the right, while the top rod moves to the right, the telescopic rod 1 stretches and pushes the support rod to the right, and air is sprayed while moving to the right, so as to blow away the aluminum chips in the first place, and avoid the support rod pressing on the aluminum chips when moving to the right, causing secondary scratches.

[0011] According to another advantageous design of the present invention, the bottom of the roller contacts the worktable, the top of the worktable is provided with a square groove, the second reciprocating screw is provided with a reciprocating helical groove, the inner wall of the second slider is provided with a movable key, and the movable key is located in the reciprocating helical groove, the top of the worktable is provided with a second motor, the output end of the second motor is fixedly connected to the second reciprocating screw, and the top of the worktable is provided with an air pump, the output end of the air pump is fixedly connected to an air pipe.

[0012] According to another advantageous design of the invention, the cooling mechanism includes a fixed base three, which is fixedly connected to the top of the worktable, and a slider three is fixedly connected to the top of the slider one. A rectangular groove is provided at the front of the fixed base three, and a telescopic rod two is fixedly connected to the left side of the rectangular groove, and a slider four is fixedly connected to the right side of the telescopic rod two.

[0013] According to another advantageous design of the present invention, the top of the slider four is rotatably connected to a rotating shaft, the circumferential surface of the rotating shaft is fixedly connected to a stop block one, the top of the rotating shaft is fixedly connected to a faucet, the rear of the faucet is fixedly connected to a water pipe, the front of the faucet is fixedly connected to a nozzle, and the front of the fixed seat three is fixedly connected to a stop block two. Under the limitation of the left stop block two, the rotating shaft rotates, driving the faucet and nozzle to rotate 90 degrees. The nozzle sprays water at a 45-degree angle to the right outer wall of the bicycle saddle connector to cool it down, and then sprays water at a 45-degree angle to the left outer wall to cool it down, thus avoiding water contact with the inner wall and reducing the risk of corrosion and oxidation of the inner wall.

[0014] According to another advantageous design of the present invention, the slider three is located in the rectangular groove, the slider four is slidably connected to the rectangular groove, a water collection groove is provided on the top of the workbench, a collection box is slidably connected inside the workbench, and a collection plate is in contact with the top of the collection box. When the cleaning frame moves to the lever, the elastic cleaning net on the rotating cleaning frame hits the rebound lever, causing vibration and shaking off the aluminum shavings adhering to the gaps in the cleaning net. The aluminum shavings fall into the square groove and are collected by the collection plate for convenient subsequent processing.

[0015] The beneficial effects of this invention are: 1. Through the coordinated operation of the lower clamping plate, upper clamping plate, insertion tube, grinding mechanism, fixed seat one, reciprocating screw one, slider one, limit rod, grinding wheel connecting rod, grinding wheel, rotating shaft, cleaning frame, top rod, support rod, fixed block, connecting block, and lever block, the reciprocating screw one drives the slider one to move to the left. The leftward movement of the slider one drives the grinding wheel connecting rod and the grinding wheel to move to the left, grinding the inner wall of the bicycle saddle insertion tube. The rubber blocks on the lower and upper clamping plates are limited by torsion springs. This limiting function can not only fix the tube during grinding, but also prevent damage to the bicycle saddle insertion tube due to the small limiting force.

[0016] 2. Through the coordinated operation of the fixed seat two, reciprocating screw two, slider two, fixed rod, support block, arc groove, telescopic rod one, air pipe, roller, square hole, and square groove, the fixed rod and support block move back and forth under the drive of the reciprocating screw two. The back and forth movement of the fixed rod and support block drives the support rod and bicycle saddle connector to move back and forth. The air pipe blows air into the support rod and through the square hole blows air into the inner wall of the bicycle saddle connector to blow away the remaining aluminum shavings from grinding. Most of the aluminum shavings will be adsorbed in the gaps of the cleaning screen of the cleaning frame, preventing the aluminum shavings from being blown around and scratching the inner wall of the bicycle saddle connector. The aluminum shavings are not scattered to various parts of the worktable, but are mainly focused on the cleaning screen and concentrated at the push block.

[0017] 3. Through the coordinated operation of fixed seat three, slider three, telescopic rod two, slider four, rotating shaft, stop one, faucet, water pipe, nozzle, stop two, and water collection tank, as slider three moves, it pushes slider four to move. The nozzle sprays water onto the outer wall of the bicycle saddle connector to cool it down. Originally, under the limit of the stop, the nozzle sprays water at a 45-degree angle to the right outer wall of the bicycle saddle connector. Slider three pushes slider four to move to the left. Under the limit of the left stop, the rotating shaft rotates, causing the faucet and nozzle to rotate 90 degrees. The nozzle sprays water at a 45-degree angle to the left outer wall of the bicycle saddle connector to cool it down, avoiding water contact with the inner wall and reducing the risk of corrosion and oxidation of the inner wall.

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figures 1-7 As shown, one embodiment of the present invention is a grinding device for the inner wall of a bicycle saddle insert pipe, comprising: a workbench 1, a lower clamping plate 2 fixedly connected to the workbench 1, an upper clamping plate 3 rotatably connected to the top of the two lower clamping plates 2 via torsion springs, a rubber block fixedly connected to the top of the lower clamping plates 2, an insert pipe 4 placed on the rubber block, a grinding mechanism 5 provided on the top of the workbench 1, a cleaning mechanism 6 provided on the top of the workbench 1, a cooling mechanism 7 provided on the top of the workbench 1, and a collection mechanism 8 provided inside the workbench 1; The grinding mechanism 5 includes a fixed base 501, which is fixedly connected to the top of the worktable 1. A reciprocating screw 502 is rotatably connected to the left and right inner walls of the fixed base 501. A slider 503 is movably connected to the circumferential surface of the reciprocating screw 502. A limit rod 504 is slidably connected to the inner circumferential surface of the slider 503. A grinding wheel connecting rod 505 is rotatably connected to the left side of the slider 503. A grinding wheel 506 is fixedly connected to the circumferential surface of the grinding wheel connecting rod 505. A rotating shaft 507 is fixedly connected to the left side of the grinding wheel connecting rod 505. A cleaning frame 508 is fixedly connected to the circumferential surface of the rotating shaft 507. A top rod 509 is rotatably connected to the left side of the rotating shaft 507. A support rod 510 is slidably connected to the inner circumferential surface of the insertion tube 4.

[0022] The grinding mechanism 5 includes a fixing block 511. The left side of the fixing block 511 is fixedly connected to the lower clamping plate 2. The top of the fixing block 511 is fixedly connected to a connecting block 512. The top of the connecting block 512 is rotatably connected to a lever 513. The reciprocating screw 502 drives the slider 503 to move to the left. The leftward movement of the slider 503 drives the grinding wheel connecting rod 505 and the grinding wheel 506 to move to the left, grinding the inner wall of the bicycle saddle connector 4. The rubber blocks on the lower clamping plate 2 and the upper clamping plate 3 are limited by torsion springs. This limitation can not only play a fixing role during grinding, but also, because the limiting force is not large, it will not damage the bicycle saddle connector 4.

[0023] The reciprocating screw 502 has a reciprocating helical groove, the inner wall of the slider 503 has a movable key, and the movable key is located in the reciprocating helical groove. The left and right sides of the limiting rod 504 are fixedly connected to the fixed seat 501. The top of the worktable 1 is equipped with a motor, and the output end of the motor is fixedly connected to the grinding wheel connecting rod 505. The top of the worktable 1 is equipped with a motor, and the output end of the motor is fixedly connected to the reciprocating screw 502. The inner wall of the cleaning frame 508 is fixedly connected with an elastic cleaning net.

[0024] Working principle: Start motor two. The output of motor two drives reciprocating screw two 602 to rotate. The rotation of reciprocating screw two 602 drives the movable key to rotate. Slider two 603 rotates under the drive of the movable key. However, due to the limitation of limit rod two, the movable key can only move back and forth in the reciprocating spiral groove, driving slider two 603 to move back and forth. Slider two 603 drives fixed rod 604 to move backward. The backward movement of fixed rod 604 drives support block 605 to move backward. The backward movement of fixed rod 604 drives support rod 510 to move backward. The backward movement of support rod 510 drives insertion tube 4 to move backward. The rubber blocks on lower clamp plate 2 and upper clamp plate 3 limit insertion tube 4 through torsion springs. This limiting function can both fix the tube during grinding and, because the limiting force is not large, prevent damage to insertion tube 4, avoiding the soft tube 4 from easily deforming under force, which would make it difficult to install on the bicycle. At this time, start motor one. The output of motor one... The rotation of the end causes the reciprocating lead screw 502 to rotate, which in turn causes the movable key to rotate. The slider 503 rotates under the influence of the movable key, but due to the limiting rod 504, the movable key can only move left and right within the reciprocating spiral groove. This causes the slider 503 to move to the left, which in turn causes the grinding wheel connecting rod 505 to move to the left. The grinding wheel connecting rod 505 then moves to the left, causing the grinding wheel 506 to move to the left. The motor drives the rotating shaft 507 and cleaning frame 508 to move to the left. The leftward movement of the rotating shaft 507 drives the push rod 509 to move to the left. The leftward movement of the push rod 509 pushes the support rod 510 to move to the left. At the same time, the motor is started. The output end of the motor drives the grinding wheel connecting rod 505 to rotate. The rotation of the grinding wheel connecting rod 505 drives the rotating shaft 507 and cleaning frame 508 to rotate. The rotation of the grinding wheel connecting rod 505 drives the grinding wheel 506 to rotate. The rotation of the grinding wheel 506 grinds the inner wall of the insertion pipe 4.

[0025] like Figures 1-7 As shown, based on the above embodiment, the cleaning mechanism 6 includes a fixed base 601, which is fixedly connected to the top of the workbench 1. A reciprocating screw 602 is rotatably connected to the front and rear inner walls of the fixed base 601. A slider 603 is movably connected to the circumferential surface of the reciprocating screw 602. A fixed rod 604 is fixedly connected to the right side of the slider 603. A support block 605 is fixedly connected to the circumferential surface of the fixed rod 604. An arc-shaped groove 606 is opened at the front of the circumferential surface of the fixed rod 604. A telescopic rod 607 is fixedly connected to the left side of the arc-shaped groove 606. A limiting rod 2 is slidably connected to the inner circumferential surface of the slider 603. The front and rear ends of the limiting rod 2 are fixedly connected to the fixed base 601.

[0026] The right side of the telescopic rod 607 contacts the support rod 510, and the left side of the support rod 510 is fixedly connected to the air pipe 608. The support rod 510 has a square hole 610 inside. The bottom of the support block 605 is rotatably connected to the roller 609. The fixed rod 604 and the support block 605 move back and forth under the drive of the reciprocating screw 602. The back and forth movement of the fixed rod 604 and the support block 605 drives the support rod 510 and the bicycle saddle connector 4 to move back and forth. The air pipe 608 blows air into the support rod 510 and blows the remaining aluminum shavings on the inner wall of the bicycle saddle connector 4 through the square hole 610. Most of the aluminum shavings will be adsorbed in the gaps of the cleaning screen of the cleaning frame 508, preventing the aluminum shavings from being blown around and scratching the inner wall of the bicycle saddle connector 4, and preventing the aluminum shavings from scattering to various places on the workbench 1. Instead, they are mainly focused on the cleaning screen and concentrated at the push block 513.

[0027] The bottom of roller 609 contacts workbench 1. A square groove 611 is provided on the top of workbench 1. A reciprocating screw 602 is provided with a reciprocating spiral groove. A movable key is provided on the inner wall of slider 603, and the movable key is located in the reciprocating spiral groove. A motor is provided on the top of workbench 1. The output end of motor 2 is fixedly connected to reciprocating screw 602. An air pump is provided on the top of workbench 1. The output end of air pump is fixedly connected to air pipe 608.

[0028] The cooling mechanism 7 includes a fixed base 3 701, which is fixedly connected to the top of the workbench 1. A slider 3 702 is fixedly connected to the top of slider 1 503. A rectangular groove is provided at the front of the fixed base 3 701. A telescopic rod 2 703 is fixedly connected to the left side of the rectangular groove. A slider 4 704 is fixedly connected to the right side of the telescopic rod 2 703.

[0029] The top of slider 4 704 is rotatably connected to a rotating shaft 705. A stop block 1 706 is fixedly connected to the circumferential surface of the rotating shaft 705. A faucet 707 is fixedly connected to the top of the rotating shaft 705. A water pipe 708 is fixedly connected to the rear of the faucet 707. A nozzle 709 is fixedly connected to the front of the faucet 707. A stop block 2 710 is fixedly connected to the front of the fixed base 3 701.

[0030] Slider 3 702 is located in a rectangular groove, and slider 4 704 is slidably connected to the rectangular groove. A water collection tank 711 is provided on the top of the workbench 1. A collection box 801 is slidably connected inside the workbench 1. The top of the collection box 801 contacts the collection plate 802. As slider 3 702 moves, it pushes slider 4 704 to move. The nozzle 709 sprays water onto the outer wall of the bicycle saddle connector 4 to cool it down. Originally, under the limitation of stop block 1 706, the nozzle 709 sprays water onto the right outer wall of the bicycle saddle connector 4 at a 45-degree angle. Slider 3 702 pushes slider 4 704 to move to the left. Under the limitation of stop block 2 710 on the left side, the rotating shaft 705 rotates, causing the faucet 707 and nozzle 709 to rotate 90 degrees. The nozzle 709 sprays water onto the left outer wall of the bicycle saddle connector 4 at a 45-degree angle to cool it down, avoiding water contact with the inner wall and reducing the risk of corrosion and oxidation of the inner wall.

[0031] Working principle: During the grinding process, air pipe 608 blows air into support rod 510 through square hole 610, blowing air into the inner wall of bicycle saddle insert pipe 4, blowing away the remaining aluminum shavings on the inner wall. Most of the aluminum shavings will be adsorbed in the gaps of cleaning screen of cleaning frame 508, preventing the aluminum shavings from being blown around and scratching the inner wall of bicycle saddle insert pipe 4, and preventing the aluminum shavings from scattering to various parts of worktable 1. Instead, the aluminum shavings are mainly focused on the cleaning screen and concentrated at the dial 513. Grinding wheel connecting rod 505 drives grinding wheel 506 to move to the right, and grinding wheel connecting rod 505 drives rotating shaft 507 and cleaning frame 508. As the top rod 509 moves to the right, the telescopic rod 607 extends and pushes the support rod 510 to the right. While moving to the right, air is sprayed to blow away the aluminum shavings immediately, preventing the support rod 510 from pressing on the aluminum shavings and causing secondary scratches as it moves to the right. When the cleaning frame 508 moves to the lever 513, the elastic cleaning screen on the rotating cleaning frame 508 hits the rebounding lever 513, causing vibration and shaking off the aluminum shavings adhering to the gaps in the cleaning screen. The aluminum shavings fall into the square groove 611 and are collected by the collection plate 802 for subsequent processing.

[0032] Slider 1 503 drives slider 3 702 to move to the left. The length of slider 3 702 within the rectangular groove is 2 / 3 of the length of the grinding wheel connecting rod 505. Therefore, when the grinding wheel connecting rod 505 moves 1 / 3 of its length, slider 3 702 does not touch slider 4 704. Nozzle 709 remains in its original state, spraying at a 45-degree angle to the right outer wall of the bicycle saddle connector 4. When the grinding wheel connecting rod 505 moves from 1 / 3 to 2 / 3 of its length, slider 3 702 pushes slider 4 704 to the left. Slider 4 704 moving to the left drives nozzle 709 to move to the left, and nozzle 709 sprays while moving to the left. During the grinding of the bicycle saddle connector 4, the following process is employed: When the grinding wheel rod 505 moves 2 / 3 to 3 / 3 of its length, the slider 4 704 moves to the left, causing the rotating shaft 705 to move to the left. The rotating shaft 705 then moves the stop block 1 706 to the left. The stop block 1 706 moves to the left and hits the stop block 2 710 on the left side, where it is stopped. Under the stop of the stop block 2 710 on the left side, the rotating shaft 705 rotates, causing the water tap 707 and nozzle 709 to rotate 90 degrees. The nozzle 709 sprays water at a 45-degree angle onto the outer left wall of the bicycle saddle connector 4 to cool it down, preventing water from touching the inner wall and reducing the risk of corrosion and oxidation of the inner wall.
