Description

Technical Field

[0001] This invention relates to the field of gear processing technology, and in particular to an anti-detachment clamp for gear manufacturing. Background Technology

[0002] As a core component in mechanical transmission, the manufacturing precision of gears directly affects the performance and lifespan of the transmission system. During gear manufacturing, especially in finishing processes such as hobbing, shaping, shaving, and grinding, or post-heat treatment processes, the gear workpiece must be securely clamped onto the machine tool table or indexing head. Reliable clamping is a crucial prerequisite for ensuring machining accuracy, improving production efficiency, and guaranteeing operational safety.

[0003] Currently, in the gear grinding process, it is necessary to clamp the two end faces (i.e., the axial direction) of the gear workpiece using a gear clamp. Common methods include hydraulic or pneumatically driven end face pressure plates or clamping with a mandrel and end face nuts. This clamping method mainly relies on the friction between the end faces to resist the cutting force, centrifugal force, or vibration generated during the processing. Because it is essentially dependent on friction and lacks effective constraints on the radial displacement and circumferential rotation of the gear, it has major technical defects such as poor stability, low safety, and easy detachment or displacement of the gear workpiece when facing complex cutting forces, lubrication environments, and vibrations. This not only seriously threatens production safety but also restricts the improvement of processing accuracy and the optimization of production efficiency. Summary of the Invention

[0004] To overcome the shortcomings of existing gear clamps in lacking effective constraints on the radial displacement and circumferential rotation of gears, this invention provides an anti-disengagement clamp for gear manufacturing.

[0005] The technical solution of the present invention is as follows: a gear manufacturing anti-detachment clamp includes an operating table, wherein the operating table is slidably connected to symmetrically distributed sliding frames, the operating table is provided with a first power module that drives the symmetrically distributed sliding frames to move, the sliding frames are rotatably connected to a rotating shaft, the operating table is provided with a second power module that drives the symmetrically distributed rotating shaft to rotate, the rotating shaft is fixedly connected to a pressure plate, the symmetrically distributed pressure plates are used to clamp spur gears, a first notched ring is fixedly connected to the outer side of one of the pressure plates, the first notched ring is provided with uniformly distributed rectangular grooves, the rectangular grooves are slidably connected to a limiting plate, the limiting plate is inserted between adjacent teeth of the spur gear to limit the spur gear.

[0006] More preferably, the pressure plate is fixed with anti-slip pads that are evenly spaced in the circumferential direction on the side near the spur gear, for fixing the spur gear.

[0007] More preferably, the limiting plate is fixedly connected to a pressure plate, which is made of rubber.

[0008] More preferably, a second notched ring is fixed to the pressure plate away from the first notched ring. The second notched ring is provided with a limiting groove that is equal in number to and corresponds one-to-one with the limiting plates. The limiting groove is used to limit the adjacent limiting plates.

[0009] More preferably, the thickness of the rectangular groove is greater than the thickness of the limiting plate, and the limiting groove has an inclined surface on the side near the spur gear, which facilitates the insertion of the limiting plate into the adjacent limiting groove.

[0010] More preferably, the first notched annulus is fixedly connected to a notched guide ring, and the side of the limiting plate near the first notched annulus is bent toward the axis of the rotating shaft. The notched guide ring is used to limit the evenly distributed limiting plates. The limiting plates are made of elastic material. The evenly distributed limiting plates are fixedly connected to a connecting ring. The connecting ring is fixedly connected to a drive frame that is rotatably connected to the rotating shaft. The sliding frame near the first notched annulus is provided with a third power module that drives the drive frame to move.

[0011] More preferably, both the pressure plate and the second notched ring are fixedly connected to the operating table with elastic pull ropes, both the first notched ring and the second notched ring are slidably connected with T-shaped rods, and both the first notched ring and the adjacent T-shaped rod and the second notched ring and the adjacent T-shaped rod are fixedly connected with tension springs. The pressure plate is provided with circumferentially evenly spaced slots, and the T-shaped rods are used to insert into the slots of adjacent pressure plates.

[0012] More preferably, the operating table is fixedly connected to symmetrically distributed limiting rods, the limiting rods are provided with guide surfaces, and the limiting rods are located on the movement path of the adjacent T-shaped rods.

[0013] More preferably, a pressure ball is rotatably connected to one side of the rotating shaft, and an insertion rod is slidably connected to the rotating shaft near the pressure ball. A spring is fixed between the insertion rod and the rotating shaft near the pressure ball. A pressure sensor for detecting the pressure of the insertion rod is provided on the rotating shaft near the pressure ball. The pressure ball is provided with a groove for the insertion rod to be inserted.

[0014] More preferably, the pressure ball has a rough surface on the side near the spur gear.

[0015] Compared with the prior art, the technical effects achieved by the present invention are as follows: The present invention initially clamps the spur gear using a pressure plate, and uses a limiting plate and a pressure plate to engage between adjacent teeth of the spur gear, preventing the spur gear from sliding relative to the pressure plate. This increases the effective constraint on the radial displacement and circumferential rotation of the spur gear, improving the fixing effect of the spur gear. The pressure plate and the first notched ring, as well as the pressure plate and the second notched ring, are locked together by a T-shaped rod, thereby preventing the limiting plate and the pressure plate from rotating relative to the pressure plate, thus preventing the spur gear from rotating relative to the pressure plate. The spur gear is fixed by clamping it at multiple points. To prevent the spur gear from slipping out between the two pressure plates during the machining process, the first and second notched rings are rotated periodically to ensure that the teeth of the spur gear being machined are always located at the notches of the first and second notched rings. This facilitates the machining of the spur gear teeth and fixes only the teeth of the spur gear that are not being machined. This improves the fixing effect of the spur gear without affecting the machining process. An alarm signal is issued by the pressure sensor through the insertion rod to alert the operator that the spur gear has slipped, reducing the occurrence of dangerous accidents and improving operational safety.

Detailed Implementation

[0025] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0026] Example 1

[0027] A type of anti-detachment clamp used in gear manufacturing, such as Figures 1-5As shown, the system includes an operating platform 1 with two sets of symmetrically distributed slides, each set containing two slides. Each slide of the operating platform 1 has a sliding frame 2 slidably connected to it. The operating platform 1 is equipped with a first power module that drives the symmetrically distributed sliding frames 2 to move. The first power module includes two hydraulic push rods symmetrically distributed on the operating platform 1. The telescopic ends of the hydraulic push rods of the operating platform 1 are fixedly connected to the adjacent sliding frames 2. The sliding frames 2 are rotatably connected to a rotating shaft 3. The operating platform 1 is also equipped with a second power module that drives the symmetrically distributed rotating shaft 3 to rotate. The second power module includes components installed on... Two motors are symmetrically distributed on the left and right sides of the operating panel 1. The output shaft of the motor of the operating panel 1 is driven by the adjacent rotating shaft 3 through a gear set. The lateral movement of the rotating shaft 3 can still ensure the power transmission between the motor of the operating panel 1 and the adjacent rotating shaft 3. A pressure plate 4 is fixedly connected to the rotating shaft 3. On the side of the pressure plate 4 near the spur gear 101, there are anti-slip pads 401 distributed circumferentially at equal intervals. The two symmetrically distributed pressure plates 4 clamp the spur gear 101 (the number of teeth is 20) through the anti-slip pads 401 on them. A first notched ring 5 is fixedly connected to the outer side of the right pressure plate 4. The notch of the first notched ring 5 is located in front of it. On the upper side, the first notched ring 5 is provided with evenly distributed rectangular grooves 501. The rectangular grooves 501 are slidably connected to a limiting plate 6. The limiting plate 6 is inserted between adjacent teeth of the spur gear 101 to limit the spur gear 101 and prevent the spur gear 101 from rotating circumferentially. A pressure plate 7 made of rubber is fixedly connected to the limiting plate 6. The limiting plate 6 drives the pressure plate 7 to be engaged between two adjacent teeth of the spur gear 101 to avoid the limiting plate 6 directly contacting the spur gear 101 and causing wear on the spur gear 101. The pressure plate 4 on the left side is fixedly connected to a second notched ring 8. The notch of the second notched ring 8 is connected to the first notched ring. The notches of the ring 5 are the same. The number of teeth exposed at the notches of the second notched ring 8 and the first notched ring 5 of the spur gear 101 is four. The second notched ring 8 is provided with a number of limiting grooves 801 that are equal to and correspond one-to-one with the limiting plates 6. The limiting grooves 801 are used to limit the adjacent limiting plates 6. The thickness of the rectangular groove 501 is greater than the thickness of the limiting plate 6, which facilitates the deformation of the right side of the limiting plate 6. Then, the spur gear 101 is fixed by the adjacent pressure plate 7. The width of the right half of the limiting groove 801 gradually increases from left to right, which facilitates the insertion of the limiting plate 6 into the adjacent limiting groove 801.

[0028] like Figures 2-5As shown, a notched guide ring 9 is fixedly connected to the right side of the first notched ring 5. The right side of the limiting plate 6 is bent towards the axis of the rotating shaft 3, which facilitates pushing the notched guide ring 9 to deform the right side of the limiting plate 6. The notched guide ring 9 is used to limit the evenly distributed limiting plates 6. The limiting plates 6 are made of elastic material. A connecting ring 10 located inside the guide ring 9 is fixedly connected to the right side of the evenly distributed limiting plates 6. A drive frame 11 rotatably connected to the rotating shaft 3 is fixedly connected to the right side of the connecting ring 10. The right sliding frame 2 is equipped with a third power module that drives the drive frame 11 to move. The third power module includes two electric push rods installed on the right sliding frame 2. The telescopic ends of the two electric push rods are fixedly connected to a connecting plate rotatably connected to the drive frame 11.

[0029] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, a T-shaped plate is installed on the lower side of the operating table 1. Elastic pull ropes 111 are fixed between the pressure plate 4 and the second notched ring 8 and the T-shaped plate of the operating table 1. The two elastic pull ropes 111 pass through the operating table 1. Two symmetrically distributed limiting rods 222 are fixed to the operating table 1. T-shaped rods 333 are slidably connected to the front sides of the first notched ring 5 and the second notched ring 8. Tension springs are fixed between the first notched ring 5 and the right-side T-shaped rod 333, and between the second notched ring 8 and the left-side T-shaped rod 333. The limiting rods 222 are provided with guide surfaces. The pressure plate 4 is provided with five circumferentially spaced slots 402, with an angle of 72° between each slot 402. The T-shaped rods 333 are used to insert into the slots 402 of adjacent pressure plates 4. The pressure plate 4 drives the T-shaped rods 333 to rotate counterclockwise. Figure 2 (Right view direction) After the limiting rod 222 contacts the adjacent T-shaped rod 333, it is guided by the T-shaped rod 333 and moves out of the adjacent slot 402.

[0030] In the initial state, the distance between the two pressure plates 4 is compared to Figure 1 The distance shown is far, and the limiting plate 6, connecting ring 10 and drive frame 11 are all compared to Figure 1 The position shown is slightly to the right, and the left side of the limiting plate 6 is not inserted between the first notched ring 5 and the second notched ring 8. The left side of the limiting plate 6 is located in the adjacent rectangular groove 501, and the T-shaped rod 333 is inserted into the adjacent front slot 402. The pressure plate 4 on the right and the first notched ring 5 are fixed by the T-shaped rod 333 on the right (as shown). Figure 6 As shown), the pressure plate 4 on the left and the second notched ring 8 are fixed by the T-shaped rod 333 on the left. When it is necessary to clamp the spur gear 101, the operator follows... Figure 1As shown, the spur gear 101 is placed between two pressure plates 4. Then, the operator drives the two sliding frames 2 to move closer to each other through the first power module. The two sliding frames 2 drive the two pressure plates 4 to move closer to the spur gear 101 through adjacent rotating shafts 3. The pressure plates 4 drive the anti-slip pads 401 on them to move closer to the spur gear 101. When the anti-slip pads 401 contact the spur gear 101 and fix the spur gear 101, the operator stops the first power module. The two pressure plates 4 no longer move closer to each other, and the clamping process of the spur gear 101 is completed.

[0031] After the clamping process of the spur gear 101 is completed, the spur gear 101 is fixed. The limiting plate 6 and the pressure plate 7 on it are inserted between the adjacent teeth of the spur gear 101. During the process of the limiting plate 6 driving the pressure plate 7 to insert between the adjacent teeth of the spur gear 101, the pressure plate 7 does not contact the spur gear 101. This facilitates the simultaneous insertion of the limiting plate 6 and the adjacent pressure plate 7 between the adjacent teeth of the spur gear 101, and avoids the limiting plate 6 contacting the spur gear 101 and scratching it. After the adjacent teeth of gear 101 are clamped together, the pressure plate 7 presses against and fixes the spur gear 101. The specific operation is as follows: After the clamping process of the spur gear 101 is completed, the operator drives the drive frame 11 to move to the left through the third power module. The drive frame 11 drives the connecting ring 10 and the limiting plate 6 to move to the left. The limiting plate 6 drives the pressure plate 7 on it to move to the left along the adjacent rectangular groove 501 and enter between the two teeth of the spur gear 101. Taking the upper limiting plate 6 as an example, the lower side of the pressure plate 7 will not be between the two teeth of the spur gear 101. In partial contact, when the left side of the limiting plate 6 is inserted into the left limiting groove 801, the left side of the limiting plate 6 is first guided by the limiting groove 801 and gradually moves downward. When the left side of the limiting plate 6 is inserted into the limiting groove 801, the connecting ring 10 continues to move to the left, causing the right side of the limiting plate 6 to bend downward under the guidance of the notch guide ring 9 and deform (the thickness of the rectangular groove 501 is greater than the thickness of the limiting plate 6, allowing the right side of the limiting plate 6 to deform). Both the left and right sides of the limiting plate 6 move downward, causing the pressure plate 7 to move downward and closely adhere to the spur gear 101. When the pressure plate 7 is in close contact with the spur gear 101, the operator stops the third power module, and the fixing process of the spur gear 101 is completed. The fixture does not insert the limiting plate 6 between the teeth of the spur gear 101 on the upper front side. The notch setting of the first notch ring 5, the second notch ring 8 and the notch guide ring 9 makes it convenient for the operator to process the upper front side of the spur gear 101. The operator can adjust the size of the notches of the first notch ring 5, the second notch ring 8 and the notch guide ring 9 and the number of limiting plates 6 according to the actual use conditions of the processing equipment.

[0032] After the spur gear 101 is fixed, the operator grinds the four teeth of the exposed part on the upper front side of the spur gear 101 (this grinding process is not limited to grinding; this fixture can be used under other suitable conditions). For example, the lowest tooth of the exposed part of the spur gear 101 is processed. After the lowest tooth of the exposed part of the spur gear 101 is processed, the operator starts the second power module, which drives the two rotating shafts 3 to rotate counterclockwise. Figure 2 (Right view direction) Two rotating shafts 3 drive the spur gear 101 to rotate counterclockwise by 18° via two pressure plates 4 and anti-slip pads 401 (the machined spur gear 101 has 20 teeth, and the angle between each tooth is 18°). During the counterclockwise rotation of the pressure plates 4, the right pressure plate 4 drives the first notched ring 5 to rotate counterclockwise via its T-shaped rod 333, and the left pressure plate 4 drives the second notched ring 8 to rotate counterclockwise via its T-shaped rod 333. The first notched ring 5 and the second notched ring 8... Together, they drive the evenly distributed limiting plates 6 to rotate counterclockwise. The evenly distributed limiting plates 6 and the spur gear 101 rotate counterclockwise synchronously. The evenly distributed limiting plates 6 drive the connecting ring 10 and the drive frame 11 to rotate counterclockwise. During the counterclockwise rotation of the first notched ring 5 and the second notched ring 8, the two elastic pull ropes 111 are stretched. When the spur gear 101 rotates 18° counterclockwise, the operator stops the second power module. At this time, the second to last tooth of the exposed part of the spur gear 101 is processed from bottom to top.

[0033] During the gear machining process, the spur gear 101 is initially clamped by the anti-slip pad 401 on the pressure plate 4. The limiting plate 6 and the pressure plate 7 are inserted between the adjacent teeth of the spur gear 101 to prevent the spur gear 101 from sliding relative to the pressure plate 4. The right pressure plate 4 and the first notched ring 5 are locked by the right T-shaped rod 333, and the left pressure plate 4 and the second notched ring 8 are locked by the left T-shaped rod 333. This prevents the limiting plate 6 and the pressure plate 7 from rotating relative to the pressure plate 4, thus preventing the spur gear 101 from rotating relative to the pressure plate 4. By clamping and fixing the spur gear 101 at multiple points, it is prevented from falling out between the two pressure plates 4 during the machining process.

[0034] The operator repeats the above steps to process all four teeth of the exposed portion of the spur gear 101 from bottom to top. After all four teeth of the exposed portion of the spur gear 101 are processed, the spur gear 101 rotates 54° counterclockwise relative to its initial state. The operator continues to repeat the above steps to make the two pressure plates 4 rotate counterclockwise. Taking the right pressure plate 4 as an example, the pressure plate 4 drives the T-shaped rod 333 to rotate counterclockwise and contact the adjacent limiting rod 222, and is limited by it to move out of the slot 402. There is a certain distance between the end of the T-shaped rod 333 and the slot 402 (e.g., Figure 7 As shown), the tension spring on the T-shaped rod 333 is stretched. At this time, the spur gear 101 rotates 72° relative to its initial position. Subsequently, the operator drives the drive frame 11 to move to the right through the third power module. The drive frame 11 drives the limiting plate 6 to move to the right through the connecting ring 10. Taking the upper limiting plate 6 as an example, the right side of the limiting plate 6 recovers its deformation, and the squeezing force of the limiting plate 6 on the spur gear 101 decreases. When the left side of the limiting plate 6 is located on the right side of the adjacent limiting groove 801, the left side of the limiting plate 6 moves upward. When the left side of the limiting plate 6 moves out of the adjacent limiting groove 801, the pressure plate 7 no longer squeezes. When the spur gear 101 is pressed, the tension of the left elastic cord 111 is released, causing the second notched ring 8 to rotate clockwise. As the limiting plate 6 continues to move to the right, when the left side of the limiting plate 6 is no longer located between the adjacent teeth of the spur gear 101, the left side of the limiting plate 6 is located within the adjacent rectangular groove 501. The operator stops the third power module, and the tension of the elastic cord 111 is released, causing the first notched ring 5 to rotate clockwise. The first notched ring 5 causes the notched guide ring 9 and the evenly distributed limiting plates 6 to rotate clockwise. The evenly distributed limiting plates 6 cause the connecting ring 10 and the drive frame 11 to rotate clockwise.

[0035] During the clockwise rotation of the first notched ring 5 (taking the first notched ring 5 as an example, the clockwise rotation of the second notched ring 8 is the same as that of the first notched ring 5), the first notched ring 5 drives the T-shaped rod 333 to rotate clockwise. The T-shaped rod 333 gradually stops being limited by the limiting rod 222. Since there is a certain distance between the end of the T-shaped rod 333 and the slot 402 (e.g., Figure 7(As shown), therefore, the T-shaped rod 333 will not be inserted into the slot 402. Instead, the tension of the spring on the T-shaped rod 333 is released, causing the end of the T-shaped rod 333 to press tightly against the outside of the pressure plate 4. Then, the T-shaped rod 333 slides upward to the next slot 402 position. When the elastic pull rope 111 is reset, the first notched ring 5 rotates 72° clockwise, and the second notched ring 8 rotates 72° clockwise. At the same time, the T-shaped rod 333 aligns with the adjacent slot 402. The tension of the spring on the T-shaped rod 333 is released, causing the T-shaped rod 333 to be inserted into the slot 402. The first notched ring 5 and the pressure plate 4 on the right are fixed, and the second notched ring 8 and the pressure plate 4 on the left are fixed. Then, the operator drives the drive frame 11 to move to the left through the third power module and continues to repeat the above steps of fixing the spur gear 101 to fix the spur gear 101 again. The first notched ring 5 and the second notched ring 8 are periodically rotated to ensure that the teeth of the spur gear 101 being processed are always located at the notches of the first notched ring 5 and the second notched ring 8. This facilitates the processing of the teeth of the spur gear 101 and fixes only the teeth of the spur gear 101 that are not being processed. This improves the fixing effect of the spur gear 101 without affecting the processing of the spur gear 101. By continuously repeating the above steps, all the teeth of the spur gear 101 are processed. When the processing of the spur gear 101 is completed, the operator stops the second power module and controls the third power module to move the evenly distributed limiting plates 6 out from between the adjacent teeth of the spur gear 101. The operator also controls the first power module to move the two pressure plates 4 away from each other. The operator then removes the processed spur gear 101.

[0036] Example 2

[0037] Based on Example 1, a gear manufacturing anti-detachment clamp, such as Figure 3 , Figure 4 and Figure 8 As shown, a pressure ball 12 is rotatably connected to the right side of the left rotating shaft 3, and a plug rod 13 is slidably connected inside the left rotating shaft 3. A spring is fixed between the plug rod 13 and the left rotating shaft 3. A pressure sensor 14 for detecting the pressure of the plug rod 13 is provided on the left rotating shaft 3. An alarm device electrically connected to the pressure sensor 14 is installed on the operating table (1). The pressure ball 12 is provided with a groove for the plug rod 13 to be inserted. In the initial state, the right end of the plug rod 13 is inserted into the groove of the pressure ball 12. The right side of the pressure ball 12 is provided with a rough surface. The right side of the pressure ball 12 is flush with the right side of the anti-slip pad 401. When the pressure ball 12 and the spur gear 101 move relative to the pressure plate 4, the plug rod 13 moves out of the groove of the pressure ball 12.

[0038] When the left rotating shaft 3 drives the left pressure plate 4 and the anti-slip pad 401 on it to clamp the spur gear 101, the rotating shaft 3 drives the pressure ball 12 to contact the left side of the spur gear 101. During the processing of the spur gear 101, if the spur gear 101 slips relative to the anti-slip pad 401, the left side of the spur gear 101 drives the pressure ball 12 to roll. The insert rod 13 is squeezed by the pressure ball 12 and moves out of the groove of the pressure ball 12. The left side of the insert rod 13 squeezes the pressure sensor 14, and the pressure sensor 14 transmits a signal and triggers the alarm device. At this time, the operator stops the processing of the spur gear 101 to prevent subsequent dangerous accidents. After adjusting the position of the spur gear 101, the operator resumes processing the spur gear 101. The pressure sensor 14 is activated by the insert rod 13 to send an alarm signal, prompting the operator that the spur gear 101 has slipped, reducing the occurrence of dangerous accidents and improving work safety.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
