Description

Technical Field

[0001] This invention belongs to the field of propeller cap cutting and drilling technology, specifically a quick positioning and clamping fixture for propeller cap cutting and drilling. Background Technology

[0002] A helicopter rotor consists of a hub, blades, and a rotor cap. The hub is where the blades are mounted and joined. It is located at the end of the rotor and is usually conical or frustum-shaped. It fits against the stern shaft, and a keyway is cut at the back of the hub, into which a key is inserted. This allows the stern shaft to drive the rotor to rotate.

[0003] The propeller cap, which is installed outside the propeller hub to reduce air resistance, requires multiple grooves and holes to meet manufacturing requirements. Due to the characteristics of the propeller cap itself, it is impossible to accurately cut the workpiece to meet the requirements without auxiliary tools. Therefore, a cutting and drilling fixture was designed to solve the worker problem. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention is: a quick positioning and clamping fixture for a paddle cap cutting drill, comprising: a base plate, wherein lifting rings are evenly arranged on the top of the base plate;

[0005] A drilling mechanism, which is mounted on top of the base plate;

[0006] A protective mechanism is evenly arranged around the drilling mechanism and is installed on the top of the base plate;

[0007] An auxiliary mechanism is installed on the top of the base plate and inside the drilling mechanism;

[0008] The drilling mechanism includes:

[0009] A cutting drill body is installed on the top of the base plate. The top of the cutting drill body is evenly provided with grooves, and the inner wall of the cutting drill body is evenly provided with sliding grooves. The cutting drill body is firmly welded to the base plate.

[0010] The observation components are uniformly arranged inside the cutting body.

[0011] Furthermore, the drilling mechanism also includes:

[0012] A shouldered drill sleeve is evenly distributed on the top of the cutting drill body;

[0013] Positioning bolts are staggered and arranged on the top of the cutting drill body.

[0014] Furthermore, the protective mechanism includes:

[0015] The driving blocks are evenly arranged on the top of the base plate and distributed around the cutting drill body;

[0016] An air intake pipe is mounted on top of the drive block;

[0017] An anti-slip block is installed on the top of the air intake pipe, and the outer wall of the anti-slip block is in contact with the outer wall of the cutting drill body.

[0018] Furthermore, the protective mechanism also includes:

[0019] A suction cup is fitted onto the inner wall of the anti-slip block, and elastic blocks are evenly distributed on the outside of the suction cup. The other end of each elastic block is connected to the inner wall of the anti-slip block.

[0020] Support rods are symmetrically arranged on the inner wall of the drive block and installed inside the drive block.

[0021] Furthermore, the protective mechanism also includes:

[0022] A bent rod, the bottom of which is rotatably connected to the top of the support rod, and the other end of which is connected to the outer wall of the anti-slip block;

[0023] Telescopic rods are symmetrically arranged on the outer wall of the drive block, and the outer wall of the telescopic rods is connected to the inner wall of the support rods;

[0024] A limiting block is installed on the top of the telescopic rod and is sleeved on the outside of the bent rod.

[0025] Furthermore, the protective mechanism also includes:

[0026] A limiting ring is sleeved on the outer wall of the limiting block, and the inner wall of the limiting ring is slidably connected to the outer wall of the limiting block. When the limiting block is moved downward by the telescopic rod, the bent rod gradually generates an outward stretching force under the action of the limiting block, so that a pull is formed between the bent rod and the anti-slip block. When the paddle cap undergoes a certain deformation, the bent rod can quickly drive the anti-slip block away from the paddle cap, thereby timely reminding the workers. When the paddle cap is cutting normally, the anti-slip block drives the suction cup to increase the fixing points around the paddle cap, making the paddle cap more stable when cutting.

[0027] A connecting block is installed at the end of the limiting block away from the limiting ring. Elastic rods are evenly arranged on the outer wall of the connecting block, and the other end of the elastic rods is connected to the outer wall of the limiting ring.

[0028] Furthermore, the auxiliary mechanism includes:

[0029] Connecting rods, which are evenly arranged inside the base plate;

[0030] A semi-circular ring is installed on the top of the connecting rod. The outer wall of the semi-circular ring is slidably connected to the inner wall of the cutting drill body. A connecting hole is opened at the bottom of the semi-circular ring. Two semi-circular rings are provided to form a circle. When not in use, the semi-circular rings are placed in the circular groove of the base plate.

[0031] A connector is mounted on the opposite side of the semicircular ring.

[0032] Furthermore, the auxiliary mechanism also includes:

[0033] Wiping pad, the wiping pad is installed on the top of the semi-circular ring;

[0034] Air extraction holes are evenly distributed on the inner surface of the semi-circular ring.

[0035] A connecting tube is installed at the bottom of a semi-circular ring. The outer wall of the connecting tube is snapped into the inner wall of the base plate. The end of the connecting tube is connected to a vacuum cleaner. The connecting tube is a flexible hose that can be rolled up but will not be flattened to prevent air from passing through.

[0036] A take-up shaft is installed at the bottom of the base plate. The connecting tube is wound around the outer wall of the take-up shaft. When the semicircular ring moves upward, the take-up shaft pulls the connecting tube open, allowing the connecting tube to move along the slot of the base plate. When the semicircular ring moves downward, the take-up shaft automatically winds up the connecting tube to prevent the connecting tube from bending and causing blockage of gas flow.

[0037] Furthermore, the observation component includes:

[0038] Insert rods are evenly arranged on the inner wall of the cutting drill body. A limit plate is provided on the inner side of the insert rods, and a connecting plate is provided on the other side of the insert rods.

[0039] The tie rods are evenly distributed on the side of the connecting plate near the cutting drill body, and the other end of the tie rods is connected to the outer wall of the cutting drill body. The tie rods are made of elastic material.

[0040] A scale plate is installed on the outer wall of the cutting drill body, and the inner wall of the scale plate is slidably connected to the outer wall of the connecting plate.

[0041] The beneficial effects of this invention are as follows:

[0042] 1. This invention, by setting up a cutting and drilling mechanism and designing a cuff groove according to process requirements, after fixing the propeller cap with the cutting and drilling body, cuts are made in the cuff groove reserved at the top of the cutting and drilling body. Drilling is performed through the pre-positioned drill die hole, so that the cuff and hole position meet the design requirements. The observation component is used to detect the distance between the outer wall of the propeller cap and the inner wall of the cutting and drilling body after the propeller cap is fixed, thereby determining whether the propeller cap is completely fitted before cutting. This avoids debris on the outer wall of the propeller cap getting stuck on the inner wall of the cutting and drilling body, causing additional deformation of the propeller cap during cutting. The cutting and drilling body surface is similar to the propeller cap surface for rough positioning, and the drill die hole formed during propeller cap forming is used for precise positioning, thereby improving processing accuracy.

[0043] 2. This invention, by setting an auxiliary mechanism, rotates downwards to place the paddle cap inside the cutting drill body, keeping the outer wall of the paddle cap in contact with the wiping blade. Then, the wiping blade cleans the side of the paddle cap, keeping the paddle cap in contact with the inner wall of the cutting drill body. During the cleaning process, dust and debris are drawn into the semi-circular ring through the air extraction hole, allowing impurities in the semi-circular ring to enter the connecting pipe and be discharged. This avoids the debris adhering to the surface of the paddle cap before processing being trapped between the cutting drill body and the paddle cap, which would cause wear or deformation during the cutting process and affect the processing accuracy of the paddle cap.

[0044] 3. This invention, by setting up a protective mechanism, uses an anti-sliding block and a suction cup in conjunction with positioning bolts to adhere to and fix the area around the paddle cap during cutting and drilling. This prevents the paddle cap from deforming or changing position during the cutting process, which could lead to a decrease in drilling accuracy. The invention also creates tension between the bent rod and the anti-sliding block, allowing the bent rod to quickly move the anti-sliding block away from the paddle cap when it deforms, thus promptly alerting the operator. When the paddle cap is cutting normally, the anti-sliding block, along with the suction cup, increases the fixing points around the paddle cap, making the paddle cap more stable during cutting and drilling, thus improving processing quality.

[0045] 4. This invention, by setting up an observation component, has the outer wall of the propeller cap in contact with the limiting plate and pushes the limiting plate outward, causing the insertion rod to move outward. The connecting plate pulls the pull rod open, so that the connecting plate is subjected to the elastic force of the pull rod. Once a change occurs, the connecting plate can quickly respond and generate displacement, which is convenient for workers to detect in time. When the connecting plate moves to a fixed position along the scale plate, the roundness of the propeller cap can also be judged by judging the relative position of the connecting plate and the scale plate, which is convenient for workers to adjust in time.

[0055] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0056] Example 1, please refer to Figures 1-5 The present invention provides a technical solution: a quick positioning and clamping fixture for a paddle cap cutting drill is described below.

[0057] Includes: a base plate 1, with lifting rings 3 evenly distributed on the top of the base plate 1;

[0058] Drilling mechanism 2 is installed on top of base plate 1;

[0059] Protective mechanism 4 is evenly arranged around the cutting and drilling mechanism 2 and is installed on the top of the base plate 1.

[0060] Auxiliary mechanism 5 is installed on the top of base plate 1 and inside the cutting and drilling mechanism 2;

[0061] Place the drilling mechanism 2 in the work area, take out the formed propeller cap, the shape of the propeller cap matches the inner cavity of the drilling mechanism 2. When placed inside the drilling mechanism 2, the auxiliary mechanism 5 cleans the side wall of the propeller cap. Then, the protective mechanism 4 is placed inside the base plate 1. After installation and fixation, the protective mechanism 4 is made to fit against the outer wall of the propeller cap, so that the auxiliary mechanism 5 can hold the outer wall of the propeller cap to prevent deformation during the drilling process. When the propeller cap is formed, through holes are evenly distributed on the extension section. After the through holes are installed with the drilling mechanism 2, tighten them to fix it. The worker can operate through the drilling mechanism 2 to complete the worker's operation needs.

[0062] The drilling mechanism 2 includes:

[0063] The cutting drill body 201 is installed on the top of the base plate 1. The top of the cutting drill body 201 is evenly provided with grooves 206, and the inner wall of the cutting drill body 201 is evenly provided with sliding grooves 203. The cutting drill body 201 is firmly welded to the base plate 1.

[0064] The observation components 204 are evenly arranged inside the cutting body 201.

[0065] The drilling mechanism 2 also includes:

[0066] Shoulder-mounted drill sleeves 205 are evenly distributed on the top of the cutting drill body 201;

[0067] Positioning bolts 202 are staggered on the top of the cutting drill body 201.

[0068] During the propeller cap forming process, through holes are evenly distributed on the extension section. After the through holes are installed in conjunction with the positioning bolts 202, they are tightened. The cuff groove 206 is designed according to the process requirements. After the propeller cap is fixed by the cutting drill body 201, the cuff groove 206 reserved on the top of the cutting drill body 201 is cut. The hole is drilled through the positioned drill die hole to ensure that the cuff and hole position meet the design requirements. The observation component 204 is used to detect the distance between the outer wall of the propeller cap and the inner wall of the cutting drill body 201 after the propeller cap is fixed, so as to determine whether the propeller cap is completely fitted before cutting. This avoids debris on the outer wall of the propeller cap getting stuck on the inner wall of the cutting drill body 201, which would cause additional deformation of the propeller cap during cutting. The rough positioning is achieved by the similarity between the surface of the cutting drill body 201 and the surface of the propeller cap, and the precise positioning is achieved by the drill die hole formed during the propeller cap forming process, thereby improving the processing accuracy.

[0069] Protective mechanism 4 includes:

[0070] Drive blocks 401 are evenly arranged on the top of the base plate 1 and distributed around the cutting drill body 201.

[0071] The suction pipe 402 is installed on the top of the drive block 401 and is connected to an external air extraction device.

[0072] Anti-slip block 403 is installed on the top of the air intake pipe 402, and the outer wall of anti-slip block 403 is in contact with the outer wall of the cutting drill body 201.

[0073] Protective mechanism 4 also includes:

[0074] The suction cup 404 is sleeved on the inner wall of the anti-slip block 403. Elastic blocks 405 are evenly arranged on the outside of the suction cup 404. The other end of the elastic block 405 is connected to the inner wall of the anti-slip block 403.

[0075] Support rod 406 is symmetrically arranged on the inner wall of drive block 401 and installed inside drive block 401.

[0076] Protective mechanism 4 also includes:

[0077] The bottom of the bent rod 407 is rotatably connected to the top of the support rod 406, and the other end of the bent rod 407 is connected to the outer wall of the anti-slip block 403.

[0078] Telescopic rod 408 is symmetrically arranged on the outer wall of drive block 401, and the outer wall of telescopic rod 408 is connected to the inner wall of support rod 406;

[0079] Limiting block 409 is installed on the top of telescopic rod 408 and is sleeved on the outside of curved rod 407.

[0080] Protective mechanism 4 also includes:

[0081] The limiting ring 410 is sleeved on the outer wall of the limiting block 409. The inner wall of the limiting ring 410 is slidably connected to the outer wall of the limiting block 409. When the limiting block 409 is driven downward by the telescopic rod 408, the bent rod 407 gradually generates an outward stretching force under the action of the limiting block 409, so that the bent rod 407 and the anti-sliding block 403 are pulled together. When the paddle cap undergoes a certain deformation, the bent rod 407 can quickly drive the anti-sliding block 403 away from the paddle cap, thereby timely reminding the staff. When the paddle cap is cutting normally, the anti-sliding block 403 drives the suction cup 404 to increase the fixing points around the paddle cap, making the paddle cap more stable when cutting.

[0082] Connecting block 411 is installed at the end of limiting block 409 away from limiting ring 410. Elastic rods 412 are evenly arranged on the outer wall of connecting block 411, and the other end of elastic rods 412 is connected to the outer wall of limiting ring 410.

[0083] After placing the paddle cap inside the cutting body 201, the anti-slip block 403 is first brought into contact with the outer wall of the paddle cap. Then, the suction device is turned on to make the suction cup 404 adhere to the outer wall of the paddle cap. The suction device is used to hold the suction cup 404 in place. Then, the drive block 401 drives the telescopic rod 408 to move downward, causing the telescopic rod 408 to pull the bending rod 407 outward to pull the anti-slip block 403. During the cutting and drilling process, the anti-slip block 403 and the suction cup 404, together with the positioning bolt 202, adhere and fix the paddle cap around itself, preventing the paddle cap from deforming or changing position during the cutting process, which would lead to a decrease in drilling accuracy. The bending rod 407 and the anti-slip block 403 are pulled together, so that when the paddle cap deforms to a certain extent, the bending rod 407 can quickly move the anti-slip block 403 away from the paddle cap, thus promptly reminding the workers. When the paddle cap is cutting normally, the anti-slip block 403 drives the suction cup 404 to increase the fixing points around the paddle cap, making the paddle cap more stable during cutting and affecting the processing quality.

[0084] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: based on embodiment 1, the auxiliary mechanism 5 includes:

[0085] Connecting rods 501 are evenly arranged inside the base plate 1;

[0086] A semi-circular ring 502 is installed on the top of the connecting rod 501. The outer wall of the semi-circular ring 502 is slidably connected to the inner wall of the cutting drill body 201. A connecting hole 508 is provided at the bottom of the semi-circular ring 502. Two semi-circular rings 502 are provided to form a circle. When not in use, the semi-circular ring 502 is placed in the circular groove 206 of the base plate 1.

[0087] Connector 503 is installed on the opposite side of semi-circular ring 502.

[0088] Auxiliary mechanism 5 also includes:

[0089] Wiping pad 504 is mounted on top of semi-circular ring 502;

[0090] Air extraction holes 505 are evenly distributed on the inner surface of the semi-circular ring 502.

[0091] Connecting pipe 506 is installed at the bottom of semi-circular ring 502. The outer wall of connecting pipe 506 is snapped into the inner wall of base plate 1. The end of connecting pipe 506 is connected to vacuum cleaner. Connecting pipe 506 is a flexible hose that can be rolled up but will not be flattened so that air cannot pass through.

[0092] The take-up shaft 507 is installed at the bottom of the base plate 1. The connecting tube 506 is wound around the outer wall of the take-up shaft 507. When the semi-circular ring 502 moves upward, the take-up shaft 507 pulls the connecting tube 506 open, so that the connecting tube 506 moves along the slot of the base plate 1. When the semi-circular ring 502 moves downward, the take-up shaft 507 automatically winds up the connecting tube 506 to prevent the connecting tube 506 from bending and causing blockage of gas flow.

[0093] Before operation, the connecting rod 501 moves the semi-circular ring 502 upward, causing the semi-circular ring 502 to open under the action of the cutting body 201. Then, it rotates downward to place the paddle cap inside the cutting body 201, ensuring that the outer wall of the paddle cap is in contact with the wiping plate 504. The sides of the paddle cap are then cleaned by the wiping plate 504, ensuring that the paddle cap is in contact with the inner wall of the cutting body 201. During the cleaning process, dust and debris are drawn into the semi-circular ring 502 through the air extraction hole 505, allowing impurities in the semi-circular ring 502 to be discharged through the connecting pipe 506. This prevents debris adhering to the surface of the paddle cap from getting stuck between the cutting body 201 and the paddle cap before processing, which could cause wear or deformation during the cutting process and affect the processing accuracy of the paddle cap.

[0094] Observation component 204 includes:

[0095] Insert rod 2041 is evenly arranged on the inner wall of the cutting drill body 201. A limit plate 2045 is provided on the inner side of the insert rod 2041, and a connecting plate 2042 is provided on the other side of the insert rod 2041.

[0096] Pull rod 2043 is evenly distributed on one side of the connecting plate 2042 near the cutting drill body 201. The other end of the pull rod 2043 is connected to the outer wall of the cutting drill body 201. The pull rod 2043 is made of elastic material.

[0097] The scale plate 2044 is installed on the outer wall of the cutting drill body 201, and the inner wall of the scale plate 2044 is slidably connected to the outer wall of the connecting plate 2042.

[0098] After the propeller cap is fixed, the outer wall of the propeller cap contacts the limiting plate 2045 and pushes the limiting plate 2045 outward, causing the insertion rod 2041 to move outward. The connecting plate 2042 pulls the pull rod 2043 open, so that the connecting plate 2042 is subjected to the elastic force of the pull rod 2043. Once a change occurs, the connecting plate 2042 can quickly respond and generate displacement, which is convenient for workers to detect in time. When the connecting plate 2042 moves to a fixed position along the scale plate 2044, the roundness of the propeller cap can also be judged by judging the relative position of the connecting plate 2042 and the scale plate 2044, which is convenient for workers to adjust in time.

[0099] The specific workflow is as follows:

[0100] Place the cutting and drilling mechanism 2 in the work area, take out the shaped paddle cap, initially, the worker rotates the paddle cap downward and places it inside the cutting and drilling body 201, so that the outer wall of the paddle cap is in contact with the wiping plate 504, and then cleans the side of the paddle cap through the wiping plate 504, so that the paddle cap is in contact with the inner wall of the cutting and drilling body 201. During the cleaning process, the dust and debris are drawn into the semi-circular ring 502 through the air extraction hole 505, so that the impurities in the semi-circular ring 502 enter the connecting pipe 506 and are discharged, so as to avoid the debris adhering to the surface of the paddle cap before processing being trapped between the cutting and drilling body 201 and the paddle cap, which would cause wear or deformation during the cutting process;

[0101] The shape of the propeller cap matches the inner cavity of the cutting and drilling mechanism 2. When the propeller cap is formed, through holes are evenly distributed on the extension section. After the through holes are installed with the positioning bolts 202, they are tightened. The cuff groove 206 is designed according to the process requirements. After the propeller cap is fixed by the cutting and drilling body 201, the cuff groove 206 reserved at the top of the cutting and drilling body 201 is cut. The hole is drilled through the positioned drill die hole so that the cuff and the hole position meet the design requirements. The observation component 204 is used to detect the distance between the outer wall of the propeller cap and the inner wall of the cutting and drilling body 201 after the propeller cap is fixed, so as to determine whether the propeller cap is completely fitted before cutting.

[0102] After placing the propeller cap inside the cutting body 201, the anti-slip block 403 is first brought into contact with the outer wall of the propeller cap. Then, the suction device is turned on to make the suction cup 404 adhere to the outer wall of the propeller cap. The suction device is used to hold the suction cup 404 in place. Then, the drive block 401 moves the telescopic rod 408 downward, causing the telescopic rod 408 to pull the curved rod 407 outward to pull the anti-slip block 403. During the cutting and drilling process, the anti-slip block 403 and the suction cup 404, together with the positioning bolts 202, adhere and fix the propeller cap to its surroundings. To prevent deformation or positional changes of the propeller cap during drilling, which could lead to a decrease in drilling accuracy, the bent rod 407 and the anti-slip block 403 are pulled together. When the propeller cap deforms to a certain extent, the bent rod 407 can quickly move the anti-slip block 403 away from the propeller cap, thus promptly alerting the operator. When the propeller cap is cutting normally, the anti-slip block 403 drives the suction cup 404 to increase the fixing points around the propeller cap, making the propeller cap more stable during drilling and affecting the processing quality. The operator can operate the drilling mechanism 2 to meet their operational needs.
