Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to a machining and grinding device. Background Technology

[0002] Machining is a crucial part of the manufacturing industry, involving the use of various mechanical equipment and processes to change the shape, size, and surface properties of materials to meet specific design requirements.

[0003] For example, the gear grinding device with announcement number CN 106825783 A includes a worktable, with a slide rail on the upper part of one side of the worktable and a grinding blade on the lower part. A motor is also mounted on the worktable, with an output shaft connected to the motor. A collection box is located below the grinding blade. A dust collection mechanism is located on one side of the worktable, comprising a frame and a dust collection gear. The dust collection gear includes an insulating part and two conductive parts, with the insulating part located between the two conductive parts, and the conductive parts being electromagnets. The frame includes a vertical rod and horizontal rods mounted at both ends of the vertical rod. A plastic rotating shaft is rotatably connected to the top horizontal rod, and the dust collection gear is mounted on the rotating shaft. A conductive strip is mounted on the bottom horizontal rod, with the top of the conductive strip contacting the end face of the dust collection gear near the worktable side, and the bottom of the conductive strip connected to a power source. A negative pressure plate is mounted on the vertical rod of the frame. This design solves the problems of inaccurate grinding, high defect rate, and low work efficiency in existing technologies. In the aforementioned device, when grinding the gear ring, due to the presence of gear grooves, the burrs deep within the gear grooves cannot be ground when the outer wall is relatively rotated and ground by the grinding head. Furthermore, manually holding the grinding machine also requires fixing the gears, and after grinding one side, it needs to be re-clamped and ground again, resulting in excessively low grinding efficiency. Therefore, a machining grinding device is proposed to solve the aforementioned problems. Summary of the Invention

[0010] Preferably, there are two sets of fixed rods, support arms, and rotating rods, arranged symmetrically front and back. The outer wall of the front rotating rod is fixedly fitted with a rubber wheel, which frictionally engages with the gear ring. The two support arms are respectively provided with meshing tooth grooves. The lower right side of the two support arms is rotatably connected to a rotating shaft via a bearing.

[0011] Preferably, the front of the grinding box is threadedly connected to a threaded push rod, and the back of the threaded push rod is rotatably connected to a wedge-shaped push block via a bearing. The top of the wedge-shaped push block has a T-shaped groove and is slidably connected to the bottom of the support arm for pulling the support arm downward. The back of the grinding box is fixedly connected to a fixing block, and the inner wall of the fixing block is rotatably connected to a U-shaped rod. One end of the U-shaped rod is rotatably connected to the inner wall of the grinding box, and the outer wall of the U-shaped rod is fitted with a coil spring for pushing the U-shaped rod to move upward around the fixing block. The other end of the U-shaped rod is rotatably connected to a belt abutment wheel for tensioning the belt.

[0012] Preferably, a receiving plate is movably connected to the center of the inner wall of the grinding box, and four fixed columns are movably connected to the four corners of the receiving plate. Each fixed column is fitted with a spring on its outer wall to support the receiving plate. The receiving plate has several through holes for grinding waste to fall to the bottom of the grinding box.

[0013] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This machining and grinding device, through a clamping mechanism, grinds burrs on the outer wall of the gear ring and within its gear groove. First, the two protective doors are opened to the sides. Then, the rotating sleeve is restricted to rotate on the fixed seat. By rotating the threaded rod, the movable block rotates, and the L-shaped push rod rotates simultaneously. The right end of the push rod presses against the sliding sleeve, pushing it to the right. The fixed sleeve restricts its movement. After pressing the first return spring, the distance between the sliding sleeve and the fixed sleeve decreases because the connecting rod, the left support rod, and the bottom form a triangle. While the length between the connecting rod and the support rod remains unchanged, the angle at the base of the triangle increases, thus changing the height of the support. By pushing the clamping rod outward, gear rings of different diameters can be fixed. Simultaneously, by rotating the gear ring and cooperating with the grinding head, the gear ring can be rotated and ground.

[0014] 2. This machining and grinding device, through its clamping mechanism, allows the rotating gear ring to rotate on a fixed base via a rotating sleeve. The rotating sleeve drives the spherical rod to rotate, and upon contact with the circular track, it generates a wave-like movement that follows the rod. This, in turn, pushes the rotating sleeve to move left and right. The sliding base further facilitates this left-right movement, thereby pushing the gear ring left and right to achieve grinding along the tooth groove direction. This simulates manual grinding by allowing the angle to be changed, enabling grinding deep into the tooth grooves and improving the grinding effect.

[0015] 3. This machining and grinding device first restricts the rotation of the rotating sleeve and rotates the threaded rod to one side, causing the movable block one to rotate, so that the spherical groove and the hemisphere are disengaged. This generates pressure and pushes the movable block two and the push rod to the right. The push rod pushes the elastic rod and the push block to the right, pushing the toothed ring on the clamping rod away from the clamping rod. Then the toothed ring is placed on the clamping rod. At the same time, during rotation, the movable block one will drive the L-shaped push rod to rotate, and then slide down from the highest point of the wave-shaped groove of the sliding sleeve. Under the push of the first return spring, the support on the sliding sleeve will be released, thereby changing the angle between the connecting rod and the support rod. This causes the clamping rod to move closer to the center and contact the clamping of the toothed ring. At the same time, the clamping rod moves to the left with the sliding sleeve a distance to promote the push block to push the toothed ring to move, so as to achieve the purpose of rapid unloading. When a new gear ring is being ground, the reverse rotation of the threaded rod causes the first movable block to rotate, making the spherical groove contact the hemisphere. Under the action of the second return spring, the second movable block and the push rod move to the left. Simultaneously, the push rod moves to the left, pulling the elastic rod and the push block to the left, facilitating the placement of the gear ring on the clamping rod. During rotation, the first movable block causes the L-shaped push rod to rotate, and as it rotates, it slides to the highest point through the wave-shaped groove of the sliding sleeve, pushing it to the right. This changes the angle of the bottom of the connecting rod and the support rod, thus altering the height of the support. By pushing the clamping rod outward, the gear ring is clamped. Once fixed, simply rotating the gear ring will cause the rotating sleeve to rotate on the fixed seat, thus achieving the functions of fixing and supporting. The rotating gear ring contacts the grinding head, thereby achieving the effect of grinding the annular outer wall of the gear ring.

[0016] 4. This machining and grinding device, by setting up a grinding mechanism, utilizes the grinding head mounted on the support arm to rotate, thereby grinding the annular outer wall of the gear ring by rotating the gear ring, improving grinding efficiency, and adapting to grinding gear rings of different diameters.

[0017] 5. This machining and grinding device, by setting up a grinding mechanism and driving it through a pulley set, has a motor installed on the left side of the front support arm to drive the front rotating rod to rotate. This rotation is achieved through the pulley set, which simultaneously drives the rubber wheel and the grinding head to rotate. At the same time, the rubber wheel drives the gear ring to rotate in the opposite direction relative to the gear ring. This improves the grinding efficiency of the gear ring and the gear grooves on its inner wall during grinding, and also allows it to grind gear rings of different sizes.

[0018] 6. This machining and grinding device can change the position of the threaded push block by rotating the threaded push rod. By adjusting the movement of the threaded push block, the angle of the front support arm around the fixed rod can be adjusted to accommodate gear rings of different sizes. Adjusting the engagement of the rubber wheel with the gear ring allows the gear ring to rotate, achieving the grinding purpose. Simultaneously, after the angles of the two support arms are changed, in order to adapt to the belt tension, a torsion spring pushes the U-shaped rod to rotate around the fixed block, thereby raising the angle of the belt contact wheel on the other side, achieving belt tension, and realizing a better transmission effect to avoid situations where transmission fails.

[0019] 7. This machining and grinding device, through the setting of the receiving plate, when the toothed ring falls from above, due to the elasticity of the spring set on it, provides elastic support to the receiving plate, thereby receiving the toothed ring falling onto the receiving plate. The impact generated after falling and contacting the receiving plate will generate vibration, thereby vibrating the waste chips that have fallen onto the receiving plate and separating them along the through hole, falling into the bottom of the grinding box, thus achieving the function of separating the ground toothed ring and waste chips, making it convenient for workers to pick up the toothed ring.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below 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] Please see Figure 1-8One embodiment of the present invention is: a machining and grinding device, comprising: a grinding box 1, two protective doors 2 installed on the front of the grinding box 1, a door panel 3 installed on the front of the grinding box 1, a clamping mechanism 4 provided inside the grinding box 1 for clamping the inner wall of a gear ring 5, and a grinding mechanism 6 provided below the clamping mechanism 4 for grinding the annular outer wall of the gear ring 5; the clamping mechanism 4 includes: a fixed base 401, a rotating sleeve 402, a threaded rod 403, a movable block 404, an L-shaped push rod 405, a sliding sleeve 406, and a clamping rod 409; the bottom of the fixed base 401 is slidably connected to the inner wall of the grinding box 1, the outer wall of the rotating sleeve 402 is rotatably connected to the inner wall of the fixed base 401 through a bearing, and the sliding sleeve... 406 is movably sleeved on the outer wall of the rotating sleeve 402, and the outer wall of the rotating sleeve 402 is fixedly sleeved with two sets of fixed sleeves. Each fixed sleeve has four support rods 408 hinged to its outer wall. The other end of each support rod 408 is hinged to the clamping rod 409. The inner wall of the gear ring 5 is in contact with the clamping rod 409. The outer wall of the sliding sleeve 406 is hinged with four connecting rods 407, and the other end of the connecting rods 407 is hinged to the clamping rod 409 for pushing the clamping rod 409 to move. The outer wall of the rotating sleeve 402 is sleeved with a first return spring 410 for pushing the sliding sleeve 406 to move to the left. The outer wall of the rotating sleeve 402 has a movable hole. The L-shaped push rod 405 is fixedly connected to the movable block 404, and the other end is in contact with the sliding sleeve 406. The sliding sleeve 406 has a wave-shaped groove.

[0024] Working principle: During machining, burrs on the outer wall of the gear ring 5 and inside its gear grooves need to be polished. First, the two protective doors 5 are opened to the sides. Then, the rotating sleeve 402 is restricted to rotate on the fixed seat 401. The rotating threaded rod 403 drives the movable block 404 to rotate, which in turn drives the L-shaped push rod 405 to rotate. The L-shaped push rod 405 is then pressed against the sliding sleeve 406 by its right end, pushing the sliding sleeve 406 to the right. The fixed sleeve restricts its movement distance. After pressing the first return spring 410, Since the connecting rod 407, the left support rod 408, and the bottom form a triangle, the distance between the sliding sleeve 406 and the fixed sleeve is reduced. However, the length between the connecting rod 407 and the support rod 408 remains unchanged. With the base shortened and the waist length unchanged, the angle at the base of the triangle becomes larger, which in turn changes the height of the support. By pushing the clamping rod 409 outward, the gear rings 5 ​​of different diameters can be fixed. At the same time, by rotating the gear ring 5 and cooperating with the grinding head 605, the gear ring 5 can be rotated and ground.

[0025] Please see Figure 1-8Based on the above embodiments, in another embodiment of the present invention, two spherical rods 418 are fixedly connected to the left side of the rotating sleeve 402, a circular track 417 is fixedly connected to the left side of the inner wall of the grinding box 1, and the surface is wavy. The other ends of the two spherical rods 418 are in contact with the circular track 417, and a slider is connected to the bottom of the fixed seat 401 and is slidably connected to the grinding box 1 through the slider.

[0026] Working principle: When the gear ring 5 is rotated, it will rotate on the fixed seat 401 through the rotating sleeve 402. The rotating sleeve 402 drives the ball rod 418 to rotate. After contacting the circular track 417, it will move in a wave-like manner, which will push the rotating sleeve 402 to move left and right. Through the sliding base, the left and right movement is achieved, which pushes the gear ring 5 left and right to achieve grinding along the direction of the tooth groove. This simulates the ability to change the angle during manual grinding, so as to grind the deep part of the tooth groove and improve the grinding effect.

[0027] Please see Figure 1-8 Based on the above embodiments, in another embodiment of the present invention, a circular plate is fixedly connected to the inner wall of the rotating sleeve 402, and a push rod 412 is provided inside the rotating sleeve 402 for moving to the right to push the gear ring 5 away from the clamping rod 409. The right end of the push rod 412 passes through the circular plate and the rotating sleeve 402 in sequence and extends outward. Four elastic rods 414 are hinged to the outer wall of the push rod 412, and a push block 413 is hinged to one end of each elastic rod 414. The four push blocks 413 are slidably connected to the clamping rod 409. The outer wall of rod 409 has a threaded rod 403 threadedly connected to the center of the left side of rotating sleeve 402. Movable block 404 is fixedly connected to the right side of threaded rod 403. Movable block 411 is fixedly connected to the left side of push rod 412. Movable block 411 has two spherical grooves. Movable block 404 has two hemispheres fixedly connected to the right side, and the hemispheres intermittently contact the spherical grooves. The inner wall of rotating sleeve 402 is provided with a second return spring 415, which is used to reset movable block 411 to move to the left.

[0028] Working principle: First, by restricting the rotation of the rotating sleeve 402 and rotating the threaded rod 403 to one side, the first movable block 404 rotates, causing the spherical groove to disengage from the hemisphere. This generates pressure and pushes the second movable block 411 and the push rod 412 to the right. The push rod 412 then pushes the elastic rod 414 and the push block 413 to the right, pushing the toothed ring 5 on the clamping rod 409 away from the clamping rod 409. Finally, the toothed ring 5 is placed back onto the clamping rod 409. Simultaneously, during rotation, the movable block 404 drives the L-shaped push rod 405 to rotate, and then slides down from the highest point of the wave-shaped groove of the sliding sleeve 406. Under the push of the first return spring 410, the support of the sliding sleeve 406 will be released, thereby changing the angle between the connecting rod 407 and the support rod 408, which causes the clamping rod 409 to move closer to the center and contact the clamping of the gear ring 5. At the same time, the clamping rod 409 moves to the left with the sliding sleeve 406 for a distance to promote the push block 413 to push the gear ring 5 to move, so as to achieve the purpose of rapid unloading. When the new gear ring 5 is being ground, the threaded rod 403 is rotated in the opposite direction to drive the movable block 404 to rotate, causing the spherical groove to contact the hemisphere. Under the action of the second return spring 415, the movable block 411 and the push rod 412 are pushed to the left. As the push rod 412 moves to the left, it pulls the elastic rod 414 and the push block 413 to the left, making it easier to place the gear ring 5 on the clamping rod 409. During the rotation, the movable block 404 drives the L-shaped push rod 405 to rotate, and the rotation... The wavy groove of the sleeve 406 is pressed and slids to the highest point, pushing it to the right, which changes the angle of the bottom of the connecting rod 407 and the support rod 408, thereby changing the height of the support. By pushing the clamping rod 409 outward, the gear ring 5 is clamped. After it is fixed, simply rotating the gear ring 5 will cause the rotating sleeve 402 to rotate on the fixed seat 401, thereby achieving the function of fixing and supporting. The rotating gear ring 5 contacts the grinding head 605, thereby achieving the effect of grinding the annular outer wall of the gear ring 5.

[0029] Please see Figure 1-8 Based on the above embodiments, in another embodiment of the present invention, the grinding mechanism 6 includes: a fixed rod 601, a support arm 602, a rotating rod 603, and a grinding head 605; one end of the fixed rod 601 is rotatably connected to the grinding box 1 through a bearing, one side of the support arm 602 is fixedly sleeved on the outer wall of the fixed rod 601, the rotating rod 603 is rotatably connected to the other side of the support arm 602 through a bearing, and the grinding head 605 is fixedly sleeved on the outer wall of the rotating rod 603 for grinding the gear ring 5.

[0030] Working principle: By setting up the grinding mechanism 6, the grinding head 605 mounted on the support arm 602 can be rotated to grind the annular outer wall of the gear ring 5, thereby improving grinding efficiency and adapting to grinding gear rings 5 ​​of different diameters.

[0031] Please see Figure 1-8Based on the above embodiments, in another embodiment of the present invention, two sets of fixed rod 601, support arm 602, and rotating rod 603 are provided and arranged symmetrically front and rear. The outer wall of the front rotating rod 603 is fixedly fitted with a rubber wheel 604, which is in frictional engagement with the gear ring 5. The two support arms 602 are respectively provided with meshing tooth grooves. The lower right side of the two support arms 602 is rotatably connected to a rotating shaft through a bearing. The two rotating shafts and the two rotating rods 603 are connected by a pulley set 606.

[0032] Working principle: The motor is installed on the left side of the front support arm 602 through the pulley group to drive the front rotating rod 603 to rotate. This is then transmitted through the pulley group 606, which in turn drives the rubber wheel 604 and the grinding head 605 to rotate. At the same time, the rubber wheel 604 drives the gear ring 5 to rotate in the opposite direction relative to the gear ring 5. This improves the efficiency of burr removal on the gear ring and the gear grooves on its inner wall during grinding, and also allows for grinding of gear rings of different sizes.

[0033] Please see Figure 1-8 Based on the above embodiments, in another embodiment of the present invention, the front of the grinding box 1 is threadedly connected to a threaded push rod 608, and the back of the threaded push rod 608 is rotatably connected to a wedge-shaped push block 607 via a bearing. The top of the wedge-shaped push block 607 is provided with a T-shaped groove and is slidably connected to the bottom of the support arm 602 for pulling the support arm 602 downward. The back of the grinding box 1 is fixedly connected to a fixing block 610, and the inner wall of the fixing block 610 is rotatably connected to a U-shaped rod 609. One end of the U-shaped rod 609 is rotatably connected to the inner wall of the grinding box 1, and the outer wall of the U-shaped rod 609 is sleeved with a coil spring 611 for pushing the U-shaped rod 609 to move upward around the fixing block 610. The other end of the U-shaped rod 609 is rotatably connected to a belt contact wheel 612 for tensioning the belt.

[0034] Working principle: By rotating the threaded push rod 608, the position of the threaded push block 608 can be changed. By adjusting the movement of the threaded push block 608, the angle of the front support arm 602 around the fixed rod 601 can be pulled down or up to accommodate different sizes of gear ring 5. Adjusting the rubber wheel 604 to mesh with the gear ring 5 allows the gear ring 5 to rotate, achieving the purpose of grinding. At the same time, after the angles of the two support arms 602 are changed, in order to adapt to the belt tension, the torsion spring 611 pushes the U-shaped rod 609 to rotate around the fixed block 610, thereby raising the angle of the belt contact wheel 612 on the other side, achieving belt tension, so as to achieve better transmission effect and avoid the situation of failure to transmit.

[0035] Please see Figure 1-8Based on the above embodiments, in another embodiment of the present invention, a receiving plate 8 is movably connected to the middle of the inner wall of the grinding box 1, and four fixing columns 7 are movably connected to the four corners of the receiving plate 8. A spring 9 is respectively sleeved on the outer wall of each fixing column 7 to support the receiving plate 8. Several through holes are opened on the receiving plate 8 for grinding waste to fall to the bottom of the grinding box 1.

[0036] Working principle: When the toothed ring 5 falls from above and comes into contact with the receiving plate 8, the elasticity of the spring 9 on it provides elastic support to the receiving plate 8, thereby catching the toothed ring 5 that falls onto the receiving plate 8. The impact generated after falling causes vibration upon contact with the receiving plate 8, which vibrates the waste chips that have fallen onto the receiving plate 8 and separates them along the through hole, allowing them to fall into the bottom of the grinding box 1. This achieves the function of separating the ground toothed ring 5 from the waste chips, making it convenient for workers to pick up the toothed ring 5.
