Description

Technical Field

[0001] This utility model belongs to the field of machining technology, and in particular relates to a deburring fixture for the outer circle of a plunger. Background Technology

[0002] As an important mechanical component, plungers are widely used in various industrial and mechanical equipment such as hydraulic presses, internal combustion engines, cylinders, and braking systems. Furthermore, ceramic plungers, with their wear resistance, high-temperature resistance, and corrosion resistance, are widely used in industries such as pharmaceuticals, chemicals, petroleum, and metallurgy. However, during the manufacturing process of plungers, burrs inevitably form on the outer circumference. These burrs not only affect the appearance of the plunger but also cause inaccuracies in machining and measurement. They can also lead to wear between parts and reduced motion accuracy. Therefore, removing burrs from the outer circumference of plungers is essential. However, current traditional plunger deburring tools still have the following problems in use:

[0003] 1. Traditional deburring of the outer diameter of plungers is generally done manually or mechanically. However, manual deburring is prone to uneven grinding thickness due to problems such as improper force control by the operator, which can easily damage the plunger while removing burrs. Mechanical deburring usually uses mechanical clamps to hold the end of the plunger for grinding, which means that the clamped end of the plunger cannot be deburred. Then, the other end is manually replaced and ground, making the deburring work very time-consuming and inefficient.

[0004] 2. When traditional plunger deburring fixtures are used for deburring, the plunger is usually clamped and fixed, and then a hydraulic cylinder is used to push the deburring equipment to perform deburring work on the outer circumference of the plunger. However, the cost of hydraulic cylinders is relatively high.

[0005] 3. Traditional plunger deburring fixtures can only fix plungers of a specific size. If you want to perform deburring work on plungers of different sizes, you need to change to a plunger deburring fixture of the corresponding size, which increases the cost of deburring the plunger outer diameter.

[0006] To address these issues, we provide a deburring tool for the outer diameter of a plunger. Utility Model Content

[0007] The purpose of this utility model is to provide a deburring fixture for the outer diameter of a plunger. By setting up a three-jaw chuck, a three-jaw chuck, a brush, brush bristles, a baffle, a limiting rod, a sliding plate, a positive thread rod, and a negative thread rod, it solves the problems of existing plunger deburring fixtures being unable to perform uniform and comprehensive deburring of the outer diameter of the plunger, having high costs, and being unable to fix plungers of different sizes.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model is a deburring tool for the outer circle of a plunger, including a base, a three-jaw chuck one, a three-jaw chuck two, and a brush cylinder; baffle one and baffle two are fixed side by side on the top of the base;

[0010] The base, baffle one, and baffle two provide support for the entire plunger outer circle deburring fixture, enabling the deburring work to be carried out normally and stably.

[0011] Two limiting rods are fixed between the baffle one and the baffle two. Three-jaw chuck one and three-jaw chuck two are arranged between the two limiting rods. The central axes of three-jaw chuck one and three-jaw chuck two are collinear. A brush cylinder is arranged above the base between three-jaw chuck one and three-jaw chuck two. The central axis of the brush cylinder is located directly below the central axis of three-jaw chuck one and three-jaw chuck two. Brush bristles are arranged in a ring array around the periphery of the brush cylinder.

[0012] Adjust the position of the movable block on the three-jaw chuck one to stably grip the plunger. Then rotate the brush cylinder, which drives the brush bristles to rotate and grind and remove the burrs on the outer circle of the plunger. After the burrs are removed, stop rotating the brush cylinder and move the three-jaw chuck two to grip the end of the plunger where the burrs have been removed. Rotate the brush cylinder again to deburr the part gripped by the three-jaw chuck one.

[0013] A sliding plate is also provided between the first baffle and the second baffle, and both of the limiting rods pass through the sliding plate and are slidably connected to it. A positive thread rod and a negative thread rod are rotatably connected to the side of the sliding plate near the first baffle between the two limiting rods. The three-jaw chuck is located between the positive thread rod and the negative thread rod, and the ends of the positive thread rod and the negative thread rod away from the sliding plate are threaded through and extend out of the first baffle.

[0014] The limiting rod ensures that the slide can only slide along the direction of the limiting rod. Since the positive thread rod and the negative thread rod are rotatably connected to the slide and screwed to the baffle, and the baffle is fixedly connected to the base, when the positive thread rod rotates in the forward direction and the negative thread rod rotates in the reverse direction, it will pull the slide along the limiting rod towards the baffle. When the positive thread rod rotates in the reverse direction and the negative thread rod rotates in the forward direction, it will push the slide along the limiting rod away from the baffle.

[0015] Furthermore, a rotating shaft is fixedly connected to the center of the end of the three-jaw chuck away from the three-jaw chuck, and a drive gear is fixedly connected to the circumference of the middle part of the rotating shaft.

[0016] Furthermore, a motor is fixedly connected to the center of the side of the baffle away from the three-jaw chuck, and the end of the rotating shaft away from the three-jaw chuck passes through the baffle and is connected to the output end of the motor.

[0017] Furthermore, a rotating rod is fixedly connected to the center of one end of the brush cylinder near the three-jaw chuck, and the end of the rotating rod away from the brush cylinder is rotatably connected to the baffle. A driven gear three is fixedly connected to the circumferential position of the rotating rod near the driving gear one, and the driven gear three meshes with the driving gear one.

[0018] The size of the driving gear 1 is much larger than the size of the driven gear 3. After the three-jaw chuck 1 grips the plunger, it starts the motor 1. The output end of the motor 1 rotates slowly in the forward direction, driving the rotating shaft 1 and the driving gear 1 to rotate slowly in the forward direction. Since the size of the driving gear 1 is much larger than the size of the driven gear 3, the driven gear 3, which meshes with the driving gear 1, rotates rapidly in the reverse direction. At the same time, it drives the rotating rod, brush cylinder and brush bristles to rotate rapidly in the reverse direction, performing deburring work on the outer diameter of the plunger gripped by the three-jaw chuck.

[0019] Furthermore, a bearing is rotatably connected to the middle of the rotating rod near the periphery of the brush cylinder, and a fixing rod is fixedly connected to the outer ring of the bearing, with the bottom end of the fixing rod fixedly connected to the upper end of the base;

[0020] The fixed rod and bearings provide support for the rotating rod, allowing it to rotate normally with the rotation of the driven gear three, while simultaneously driving the brush cylinder and brush bristles to rotate.

[0021] Furthermore, a rotating shaft is rotatably connected to the side of the sliding plate near the three-jaw chuck, and the end of the rotating shaft away from the sliding plate is fixedly connected to the three-jaw chuck. A driving gear is fixedly connected to the circumference of the middle part of the rotating shaft. A driven gear is fixedly connected to the circumference of the positive thread rod and the negative thread rod near the driving gear, respectively, and driven gears are meshed with driving gear.

[0022] When the second driving gear rotates in the reverse direction, the first driven gear and the second driven gear rotate in the forward direction, thereby pulling the slide along the limit rod towards the first baffle. When the second driving gear rotates in the forward direction, the first driven gear and the second driven gear rotate in the reverse direction, thereby pushing the slide along the limit rod away from the first baffle. At the same time, as the slide moves away from the first baffle, the second rotating shaft, which is fixedly connected to the second driving gear, also rotates in the forward direction, thereby driving the second three-jaw chuck and the plunger held by the second three-jaw chuck to rotate in the forward direction. Under the action of the brush cylinder and bristles rotating in the reverse direction, the outer circle of the plunger is deburred.

[0023] Furthermore, a motor is fixedly installed on the side of the sliding plate away from the three-jaw chuck, and the rotating shaft passes through the sliding plate and is connected to the output end of the motor.

[0024] When motor two is started, its output end rotates in either the forward or reverse direction, which in turn drives shaft two and drive gear two to rotate in either the forward or reverse direction.

[0025] This utility model has the following beneficial effects:

[0026] This invention solves the problem of not being able to perform uniform and comprehensive deburring on the outer circle of a plunger by setting up a three-jaw chuck, a three-jaw chuck, a brush barrel, and brush bristles. First, the three-jaw chuck grips one end of the plunger, and the brush barrel and brush bristles rotate to deburr the part of the plunger that is not gripped. Then, the three-jaw chuck is moved to grip the other end of the plunger, and the brush barrel and brush bristles rotate to deburr the part gripped by the three-jaw chuck. This achieves the purpose of uniform and comprehensive deburring on the outer circle of the plunger and improves the deburring effect.

[0027] This invention solves the problem of high cost in deburring fixtures for the outer diameter of plungers by setting up a baffle, a limiting rod, a sliding plate, a positive thread rod, and a negative thread rod. When the positive thread rod is rotated in the forward direction and the negative thread rod is rotated in the reverse direction, the baffle is fixed, so the positive thread rod and the negative thread rod will pull the sliding plate along the limiting rod to move closer to the baffle. Conversely, when the positive thread rod is rotated in the reverse direction and the negative thread rod is rotated in the forward direction, the sliding plate will move away from the baffle. This achieves the purpose of deburring the outer diameter of plungers at a lower cost.

[0028] This invention solves the problem of not being able to fix plungers of different sizes by setting up a three-jaw chuck first and a three-jaw chuck second; by adjusting the movable blocks of the three-jaw chuck first and the three-jaw chuck second, plungers of different sizes can be fixed, thus achieving the purpose of fixing plungers of different sizes.

[0029] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0039] Please see Figure 1-5 This utility model is a deburring tool for the outer circle of a plunger, including a base 1, a three-jaw chuck 1 2, a three-jaw chuck 2 3 and a brush cylinder 4; baffle 1 101 and baffle 2 104 are fixed side by side above the base 1.

[0040] Base 1, baffle 101 and baffle 2 104 provide support for the entire plunger outer circle deburring fixture, so that the deburring work can be carried out normally and stably.

[0041] Two limiting rods 102 are fixed together between baffle 101 and baffle 204. Three-jaw chuck 12 and three-jaw chuck 23 are arranged between the two limiting rods 102. The central axes of three-jaw chuck 12 and three-jaw chuck 23 are collinear. A brush cylinder 4 is arranged above the base 1 between three-jaw chuck 12 and three-jaw chuck 23. The central axis of brush cylinder 4 is located directly below the central axis of three-jaw chuck 12 and three-jaw chuck 23. Brush bristles 401 are arranged in a ring array around the brush cylinder 4.

[0042] Before deburring, first adjust the position of the movable block on the three-jaw chuck 2 to stably grip the plunger. Then, rotate the brush cylinder 4, causing the bristles 401 to rotate and grind and remove the burrs on the outer circumference of the plunger. After the burrs are removed, stop rotating the brush cylinder 4, move the three-jaw chuck 3, and adjust the position of the movable block on the three-jaw chuck 3 to stably grip the end of the plunger that has been deburred. Adjust the position of the movable block on the three-jaw chuck 2 to release the plunger. Move the three-jaw chuck 2 3 so that the un-grinded part of the plunger is above the brush cylinder 4 and the bristles 401. Rotate the brush cylinder 4 again to deburr the part gripped by the three-jaw chuck 2.

[0043] Among them, such as Figure 1-3 As shown, a rotating shaft 201 is fixedly connected to the center of one end of the three-jaw chuck 2 away from the three-jaw chuck 3. A drive gear 202 is fixedly connected to the circumference of the middle part of the rotating shaft 201. When the rotating shaft 201 rotates, it will also drive the drive gear 202 and the three-jaw chuck 2 to rotate.

[0044] Among them, such as Figure 1-3 As shown, a motor 203 is fixedly connected to the center of the side of the baffle 101 away from the three-jaw chuck 2. The end of the rotating shaft 201 away from the three-jaw chuck 2 passes through the baffle 101 and is connected to the output end of the motor 203. When the motor 203 is started, the output end of the motor 203 will rotate, thereby driving the rotating shaft 201 to rotate.

[0045] Among them, such as Figure 1-4 As shown, a rotating rod 402 is fixedly connected to the center of one end of the brush cylinder 4 near the three-jaw chuck 2. The end of the rotating rod 402 away from the brush cylinder 4 is rotatably connected to the baffle 101. A driven gear 3 404 is fixedly connected to the circumferential position of the rotating rod 402 near the driving gear 202. The driven gear 3 404 meshes with the driving gear 202.

[0046] The size of the driving gear 202 is much larger than that of the driven gear 3. After the three-jaw chuck 2 grips the plunger, it starts the motor 203. The output end of the motor 203 rotates slowly in the forward direction, which simultaneously drives the rotating shaft 201, the driving gear 202, the three-jaw chuck 2, and the plunger to rotate slowly in the forward direction. Since the size of the driving gear 202 is much larger than that of the driven gear 3, the driven gear 3 404, which meshes with the driving gear 202, will rotate rapidly in the reverse direction. At the same time, it drives the rotating rod 402, the brush cylinder 4, and the brush bristles 401 to rotate rapidly in the reverse direction. The forward rotation of the plunger and the reverse rotation of the brush bristles 401 enable the deburring of the outer circle of the plunger to be completed more quickly, saving working time.

[0047] Among them, such as Figure 1-4As shown, a bearing 4031 is rotatably connected to the middle of the rotating rod 402 near the periphery of the brush cylinder 4. A fixing rod 403 is fixedly connected to the outer ring of the bearing 4031, and the bottom end of the fixing rod 403 is fixedly connected to the upper end of the base 1.

[0048] The fixed rod 403 and the bearing 4031 provide support for the rotating rod 402, so that the rotating rod 402 can rotate normally with the rotation of the driven gear 404, and at the same time drive the brush cylinder 4 and the brush bristles 401 to rotate.

[0049] The working principle of this embodiment is as follows: Before deburring, the position of the movable block on the three-jaw chuck 2 is first adjusted to stably grip the plunger. Then, the motor 203 is started, and the output end of the motor 203 rotates in the forward direction, thereby driving the rotating shaft 201 to rotate in the forward direction. When the rotating shaft 201 rotates in the forward direction, it drives the drive gear 202, the three-jaw chuck 2, and the plunger to rotate in the forward direction. Since the size of the drive gear 202 is much larger than the size of the driven gear 404, the driven gear 404 meshing with the drive gear 202 will quickly rotate in the reverse direction, while simultaneously driving the rotating rod 402. The brush cylinder 4 and brush bristles 401 rotate rapidly in opposite directions. With the forward rotation of the plunger and the reverse rotation of the brush bristles 401, the deburring of the outer circle of the plunger is completed quickly. Then, the motor 203 is turned off, the three-jaw chuck 3 is moved, and the position of the movable block on the three-jaw chuck 3 is adjusted so that it stably grips the end of the plunger that has been deburred. The position of the movable block on the three-jaw chuck 2 is adjusted, the plunger is released, and the three-jaw chuck 2 is moved so that the un-polished part of the plunger is above the brush cylinder 4 and brush bristles 401. The motor 203 is restarted to perform deburring on the part gripped by the three-jaw chuck 2. Specific Implementation Example 2

[0050] Please see Figure 1-5 Based on the first specific embodiment, a sliding plate 103 is also provided between the first baffle 101 and the second baffle 104, and both limiting rods 102 pass through the sliding plate 103 and are slidably connected to the sliding plate 103. A positive thread rod 303 and a reverse thread rod 305 are rotatably connected on the side of the sliding plate 103 between the two limiting rods 102 that is close to the first baffle 101. The three-jaw chuck 2 3 is located between the positive thread rod 303 and the reverse thread rod 305, and the ends of the positive thread rod 303 and the reverse thread rod 305 that are away from the sliding plate 103 are threaded through and extend out of the first baffle 101.

[0051] The setting of the limiting rod 102 ensures that the slide plate 103 can only slide along the direction of the limiting rod 102. Since the positive thread rod 303 and the negative thread rod 305 are rotatably connected to the slide plate 103 and screwed to the baffle 101, and the baffle 101 is fixedly connected to the base 1, when the positive thread rod 303 rotates in the forward direction and the negative thread rod 305 rotates in the reverse direction, it will pull the slide plate 103 to move closer to the baffle 101 along the limiting rod 102; and when the positive thread rod 303 rotates in the reverse direction and the negative thread rod 305 rotates in the forward direction, it will push the slide plate 103 to move away from the baffle 101 along the limiting rod 102.

[0052] Among them, such as Figure 1-5 As shown, a rotating shaft 301 is rotatably connected to the side of the slide plate 103 near the three-jaw chuck 3. The end of the rotating shaft 301 away from the slide plate 103 is fixedly connected to the three-jaw chuck 3. A driving gear 302 is fixedly connected to the circumference of the middle part of the rotating shaft 301. A driven gear 304 and a driven gear 306 are fixedly connected to the circumference of the driving gear 302 near the positive thread rod 303 and the reverse thread rod 305, respectively. The driven gear 304 and the driven gear 306 mesh with the driving gear 302.

[0053] Rotating the second shaft 301 drives the second drive gear 302 to rotate. When the second drive gear 302 rotates in the reverse direction, the driven gears 304 and 306 meshing with the second drive gear 302 will rotate in the forward direction, thereby pulling the slide plate 103 along the limit rod 102 towards the baffle 101. When the second drive gear 302 rotates in the forward direction, the driven gears 304 and 306 meshing with the second drive gear 302 will rotate in the reverse direction, thereby pushing the slide plate 103 along the limit rod 102 away from the baffle 101. At the same time, as the slide plate 103 moves away from the baffle 101, the second shaft 301 is in the forward rotation state, thereby driving the three-jaw chuck 23 and the plunger held by the three-jaw chuck 23 to rotate in the forward direction. Under the action of the brush cylinder 4 and the brush bristles 401 rotating in the reverse direction, the outer circle of the plunger is deburred.

[0054] Among them, such as Figure 1-5 As shown, a motor 307 is fixedly installed on the side of the slide plate 103 away from the three-jaw chuck 3, and a rotating shaft 301 passes through the slide plate 103 and is connected to the output end of the motor 307 for transmission.

[0055] When motor 2 (307) is started, the output end of motor 2 (307) rotates in either the forward or reverse direction, which in turn drives shaft 2 (301) and drive gear 2 (302) to rotate in either the forward or reverse direction.

[0056] The working principle of this embodiment is as follows: After the three-jaw chuck 12 grips the plunger to complete the deburring work, motor 1203 is turned off, and motor 2307 is started, causing the output end of motor 2307 to rotate in reverse. This causes shaft 2301 and drive gear 2302 to rotate in reverse, and driven gears 1204 and 2206, meshing with drive gear 2302, to rotate in the forward direction. This pulls the slide plate 103 along the limit rod 102 towards the baffle 101. When the three-jaw chuck moves to the end where the plunger is far from the end of the three-jaw chuck 12, the movable blocks on the three-jaw chuck 12 and three-jaw chuck 23 are adjusted, causing the three-jaw chuck 12 to release the plunger, and the three-jaw chuck 23 to grip the plunger. Motor 1203 is then started. The output end of 3 rotates in the forward direction, causing the rotating shaft 201 and the driving gear 202 to rotate in the forward direction, while the driven gear 404, the rotating rod 402, the brush cylinder 4, and the brush bristles 401 rotate in the reverse direction. This starts the motor 307 and causes its output end to rotate in the forward direction, allowing the rotating shaft 301 and the driving gear 302 to rotate in the forward direction. The driven gears 304 and 306, which mesh with the driving gear 302, will rotate in the reverse direction, thereby pushing the slide plate 103 to move away from the baffle 101 along the limit rod 102. The three-jaw chuck 3 and the plunger held by the three-jaw chuck 3 rotate in the forward direction, and under the action of the brush cylinder 4 and the brush bristles 401 rotating in the reverse direction, the outer circle of the plunger is quickly deburred.

[0057] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
