Description

Technical Field

[0001] This invention relates to the field of diamond processing technology, specifically to a diamond roller grinding equipment for fine treatment of inner hole walls. Background Technology

[0002] As a core tool in the field of precision machining, diamond rollers have diamond abrasive grains solidified on their surface, which have extremely high hardness and wear resistance, enabling efficient and precise machining of difficult-to-machine materials such as quenched steel, cemented carbide, and ceramics.

[0003] In the fine processing of inner hole walls, diamond roller grinding equipment drives the roller to rotate at high speed and feed along a specific trajectory. It uses the micro-cutting action of abrasive grains to grind, hone or polish the inner hole wall. It can precisely control the dimensional accuracy (micron-level tolerance), surface roughness (Ra≤0.1μm) and geometric accuracy (such as roundness and cylindricity) of the inner hole. It is widely used in the processing of key components such as turbine holes of aerospace engines, inner holes of automotive fuel injectors, and precision bearing rings. It is a key technical means to achieve the precision requirements of core components of high-end equipment.

[0004] In conjunction with the above, it should be noted that: Chinese Patent Application No. CN2021226108732 discloses a grinding device for diamond roller production, which has a fastening knob for fixing the position of the annular sleeve installed on the circumferential surface of the annular base, and a clamping mechanism set on the upper part of the annular support plate. Three claws are evenly arranged in a circle on the upper part of the annular support plate, and the claws are horizontally rotatably connected to the annular base through pins. The outer end of the claws is provided with a movable groove, and a positioning pin is provided in the movable groove and fixedly connected to the annular support plate.

[0005] In reality, the above-mentioned device requires continuous transport of diamond rollers to the device, which poses risks such as efficiency, safety and equipment damage during continuous transport and loading. In addition, this only considers the wear of the loading limit, while the subsequent impact of the weight of the diamond rollers themselves means that processing and unloading also involve processing risks. Summary of the Invention

[0006] The purpose of this invention is to provide a diamond roller grinding machine for fine treatment of inner hole walls, in order to solve the problems mentioned above.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a diamond roller grinding equipment for fine treatment of inner hole walls, comprising a conveyor frame, wherein a plurality of conveyor rollers are arranged in the center of the conveyor frame, and side push arms are symmetrically arranged on the inner walls of both sides of the conveyor frame near the conveyor rollers, and a grinding suspension is mounted on the top of the conveyor frame above the conveyor rollers.

[0008] The main extension cylinder column is sleeved at the top center of the grinding suspension. Several sets of claw buckle frames are arranged around the outer periphery of the main extension cylinder column. A grinding disc facing the conveying roller is arranged at the bottom of the main extension cylinder column. A guide plate that cooperates with the outer periphery of the grinding disc is arranged at the bottom of the claw buckle frame.

[0009] The bottom center of the conveyor frame is provided with a support box located below the conveyor rollers. Inside the support box is a strip-shaped support plate that runs through the conveyor frame and extends through the gaps between several sets of conveyor rollers. A slag collection box is arranged side by side on the end face of the support box.

[0010] Furthermore, the top two ends of the conveyor plate frame are symmetrically provided with conveyor belts parallel to the conveyor rollers. The inner walls on both sides of the conveyor plate frame are recessed and provided with adjustment grooves that cooperate with the side push arm rods. The inner wall at the top of the conveyor plate frame is recessed and provided with several sets of slag collection grooves located below the conveyor rollers. Lifting brushes are slidably provided inside the slag collection grooves. A perforated frame is provided between the several sets of slag collection grooves.

[0011] Furthermore, one end of the side push arm is provided with a rotary cylinder that is rotatably connected to the inside of the adjustment groove, a rotary contact arm is sleeved on the side wall of one end of the side push arm, and an assist arm is sleeved on the inner wall of the other end of the side push arm. The assist arm and the surface of the rotary contact arm are in movable contact, and a rotary cylinder is provided at the connection point between the assist arm and the side push arm.

[0012] Furthermore, the outer walls at both ends of the perforated suspension are symmetrically provided with outer lifting cylinders, and jet sloping plates are fitted on the outer walls of the end faces of the outer lifting cylinders. The inner walls on both sides of the perforated suspension are symmetrically provided with inner lifting cylinders, and compression cylinder arms are provided on the inner walls of the inner lifting cylinders. Arc-shaped compression plates are provided on the arms of the compression cylinder arms, and several sets of telescopic anti-slip contact rods are provided on the inner walls of the arc-shaped compression plates.

[0013] Furthermore, the main extension cylinder column is sleeved through and connected to the top center of the grinding hole suspension, a grinding motor is provided on the top side of the grinding disc, an air intake ring is provided in the recessed edge of the bottom inner wall of the grinding disc, and a docking sleeve that is driven and connected to the grinding motor is provided at the bottom center of the grinding disc.

[0014] Furthermore, several sets of propulsion cylinders are embedded in the top frame of the claw-locking bin, an inner sliding rod is slidably sleeved inside the guide plate, a deflection grab rod is rotatably sleeved at the bottom of the inner sliding rod, a guide frame is provided on the bottom outer wall of the guide plate, a slider is sleeved inside the guide frame, and a guide rotating rod that contacts and connects with the deflection grab rod is sleeved at the bottom of the slider, and a rotary cylinder is provided between the guide rotating rod and the slider.

[0015] Furthermore, several sets of lifting cylinder frames are symmetrically arranged on the inner walls of both sides of the lifting box. The lifting cylinder frames are connected to both sides of the strip support plate, and the top of the strip support plate is slidably sleeved with the perforated frame.

[0016] Furthermore, the slag collection box has symmetrically arranged guide troughs on both sides of one end, which are connected to the slag collection channel. An exhaust fan is installed on the top wall inside the slag collection box. A slag collection box is slidably sleeved on the end of the slag collection box away from the lifting box.

[0017] The beneficial effects of this invention are:

[0018] 1. This invention uses a rotary cylinder to drive a side push arm to rotate around an adjusting groove as an axis, combined with a rotary cylinder to push an auxiliary arm to contact a rotating contact arm, forming a "rotation + push" composite power. This can dynamically adjust the positional deviation on the conveying roller according to the size of the diamond roller, solving the problems of low efficiency and poor accuracy of traditional manual positioning. The non-contact power superposition design avoids damage to the roller surface precision caused by rigid collisions. It is suitable for the pretreatment of diamond rollers with micron-level precision requirements and features a dual-cylinder linkage positioning technology.

[0019] 2. This invention uses a lifting cylinder frame to drive the strip pallet to rise synchronously from the gap between the conveying rollers. In conjunction with the inner lifting cylinder, the arc-shaped extrusion plate forms a notched circular limiting structure, realizing the continuous execution of the three-stage action of "lifting-adjusting-lifting". The single adjustment time is shortened, and the efficiency is improved compared with traditional mechanical adjustment. The secondary adjustment design during the waiting period of the strip pallet can correct the offset caused by the weight of the rollers during the conveying process, ensuring that its axis is coaxial with the grinding disc perforated grinding part, and dynamically and synchronously lifting and lowering.

[0020] 3. This invention provides surface contact limiting through an arc-shaped extrusion plate, combined with point-contact pressure feedback from a telescopic anti-slip contact rod, forming a dual mechanism of "surface contact stabilization + point contact anti-slip". When the pushing force of the extrusion cylinder arm increases, the compression of the anti-slip rod is linearly related to the contact force, which can adapt to the adaptive clamping of rollers of different diameters, improve the anti-slip coefficient, and the contact rod has a built-in micro-spring damping structure to avoid scratches on the roller surface caused by rigid contact. At the same time, the friction force is dynamically adjusted by changing the contact area, thus constructing a surface contact + point-contact anti-slip structure.

[0021] 4. This invention uses a claw-locked bin frame to drive a deflecting gripper rod to tilt and contact the bottom contour of the roller through multi-axis linkage of a pushing cylinder, a secondary pushing cylinder, and an inner pushing cylinder. This, together with a strip-shaped support plate and an arc-shaped extrusion plate, forms a three-dimensional limiting system of top pressing, middle clamping, and bottom contraction, solving the problem of easy shaking in traditional single-plane clamping. During the grinding process, the roller axially jumps, and under the synergistic action of multiple axial forces, it can withstand the increase in grinding torque, making it suitable for the powerful grinding of high-hardness materials.

[0022] 5. This invention creates a negative pressure environment by using an exhaust fan to guide the slag and collect the slag, and combines this with the directional blowing of the jet plate to ensure that the slag-containing gas generated during grinding is sucked into the slag collection box with an efficiency of >90%, thus ensuring that the dust concentration in the workshop is reduced to the occupational health standard requirements.

[0034] 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.

[0035] Example 1: Please refer to Figure 1 - Figure 9 As shown, this embodiment is a diamond roller grinding equipment for fine treatment of inner hole walls, including a conveyor plate frame 1, a number of conveyor rollers 103 are arranged in the center of the conveyor plate frame 1, and side push arm rods 7 are symmetrically arranged on the inner walls of both sides of the conveyor plate frame 1 near the conveyor rollers 103. A grinding suspension 2 is mounted on the top of the conveyor plate frame 1 above the conveyor rollers 103.

[0036] The main extension cylinder column 4 is sleeved at the top center of the grinding suspension 2. Several sets of claw buckle frames 3 are arranged around the outer periphery of the main extension cylinder column 4. The grinding disc 402 facing the conveying roller 103 is arranged at the bottom of the main extension cylinder column 4. The guide plate 302 that cooperates with the outer periphery of the grinding disc 402 is arranged at the bottom of the claw buckle frame 3.

[0037] The top two ends of the conveyor plate frame 1 are symmetrically provided with conveyor belts 101 parallel to the conveyor rollers 103. The inner walls on both sides of the conveyor plate frame 1 are recessed and provided with adjustment grooves 102 that cooperate with the side push arm rods 7. The inner wall at the top of the conveyor plate frame 1 is recessed and provided with several sets of slag collection grooves 105 located below the conveyor rollers 103. Lifting brushes 106 are slidably arranged inside the slag collection grooves 105. The grooves 104 are provided between the several sets of slag collection grooves 105.

[0038] Diamond rollers awaiting hole grinding are stored along the surface of the conveyor belt 101 on the conveyor plate frame 1. The conveyor belt 101 smoothly transports them close to the conveyor roller 103. During the alternating entry of the diamond rollers into the surface of the conveyor roller 103, the side push arm 7 is used to adjust the diamond rollers to be close to the center area of ​​the surface of the conveyor roller 103, so as to facilitate efficient and precise clamping, positioning and hole grinding of them in the future.

[0039] One end of the side push arm 7 is provided with a rotary cylinder 1 that is rotatably sleeved inside the adjustment groove 102. A rotary contact arm 701 is sleeved on the side wall of one end of the side push arm 7, and an assist arm 702 is sleeved on the inner wall of the other end of the side push arm 7. The assist arm 702 is in movable contact with the surface of the rotary contact arm 701, and a rotary cylinder 2 is provided at the connection point between the assist arm 702 and the side push arm 7. A rotary motor or cylinder drive can be provided between the side push arm 7 and the rotary contact arm 701.

[0040] Driven by rotary cylinder one, the side push arm 7 rotates around the inner end of the adjusting groove 102 as the central axis. Rotary cylinder two further drives the booster arm 702 to unfold. The unfolding of the booster arm 702 is used to contact the outer wall surface of the rotating contact arm 701, causing the rotating contact arm 701 to further increase the deflection rotation power under its original rotational power, so as to adjust and guide the position of the diamond roller on the conveyor roller 103 according to actual needs.

[0041] The grinding suspension 2 is symmetrically equipped with external lifting cylinders 201 on the outer walls of both ends. The outer walls of the end faces of the external lifting cylinders 201 are equipped with air jet ramps 202. When the diamond roller enters its internal cavity area, the external lifting cylinders 201 operate synchronously to carry several sets of air jet ramps 202 down to a certain height. This facilitates air blowing on the top area of ​​the diamond roller that is about to be ground. It also helps the slag-containing gas generated during the grinding of the hole to flow downward in a concentrated manner under the influence of airflow interference and the negative pressure environment of the active extraction of the exhaust fan 602, thereby reducing interference with the external processing environment.

[0042] The inner walls of the two sides of the ground hole suspension 2 are symmetrically provided with inner lifting cylinders 203. The inner walls of the inner lifting cylinders 203 are provided with extrusion cylinder arms 204. The arms of the extrusion cylinder arms 204 are provided with arc-shaped extrusion plates 205. The inner walls of the arc-shaped extrusion plates 205 are provided with several sets of telescopic anti-slip contact rods 206.

[0043] The inner lifting cylinder 203, during the lifting and lifting of the diamond roller, drives the arc-shaped extrusion plate 205 to approach through the extrusion cylinder arm 204, causing several sets of arc-shaped extrusion plates 205 to move towards the center to form a symmetrical notched circular ring limiting structure. As the arc-shaped extrusion plate 205 contacts the outer wall of the diamond roller, several sets of telescopic anti-slip contact rods 206 contact the surface of the diamond roller.

[0044] As the pushing force of the extrusion cylinder arm 204 gradually increases, several sets of telescopic anti-slip contact rods 206 are compressed and slidably embedded into the arc-shaped extrusion plate 205. Combined with the coordinated operation of the arc-shaped extrusion plate 205 and several sets of telescopic anti-slip contact rods 206, a one-sided contact anti-slip and several sets of point-contact anti-slip are constructed, thereby limiting the diamond roller to the center. As the diamond roller continues to rise, the inner lifting cylinder 203 and the lifting cylinder frame 502 maintain a synchronous rising rate.

[0045] The main extension cylinder 4 is sleeved through the center of the top of the grinding suspension 2. A grinding motor 401 is provided on the top side of the grinding disc 402. An air intake ring 403 is recessed on the inner edge of the bottom of the grinding disc 402. A docking sleeve 404 is provided at the center of the bottom of the grinding disc 402 and is connected to the grinding motor 401. The main extension cylinder 4 drives the grinding disc 402 to slide down along the inner wall of the top of the grinding suspension 2 and approach the diamond roller that is limited. The docking sleeve 404 is on the inner wall of the grinding disc 402.

[0046] As the diamond roller needs to be processed, a new piercing and grinding workpiece is replaced. As the diamond roller rises and the grinding disc 402 slides down, the piercing and grinding workpiece penetrates into the mounting hole that has been machined in the middle of the diamond roller. With the operation of the grinding motor 401, the grinding motor 401 drives the mating sleeve 404 to rotate inside the grinding disc 402 through the coupling or other suitable related components, thereby performing smooth grinding treatment on the inside of the mounting hole of the diamond roller.

[0047] Several sets of propulsion cylinders 301 are embedded in the top frame of the claw-locking bin 3. An inner slide rod 303 is slidably sleeved inside the guide plate 302. A deflection grab rod 304 is rotatably sleeved at the bottom of the inner slide rod 303. A guide frame 305 is provided on the bottom outer wall of the guide plate 302. A slider is sleeved inside the guide frame 305. A guide rotation rod 306 that contacts and connects with the deflection grab rod 304 is sleeved at the bottom of the slider. A rotary cylinder 3 is provided between the guide rotation rod 306 and the slider.

[0048] Before the hole grinding, the claw-locking chamber 3 drives the guide plate 302 to slide down through the pushing cylinder. The guide plate 302 and the outer wall of the grinding disc 402 are slidably connected by metal fasteners. During the extension and sliding of the guide plate 302, the guide frame 305 unfolds synchronously according to the height requirements of the diamond roller body. The inner wall of the guide plate 302 is provided with a secondary pushing cylinder connected to the inner slide rod 303, which is used to drive the inner slide rod 303 to unfold. The slider inside the guide frame 305 slides and adjusts along the inside of the guide frame 305 according to the position adjustment requirements. The rotary cylinder 3 on the slider drives the guide rotating rod 306 to deflect. The guide rotating disc deflects and contacts the pushing deflection gripper 304, causing the deflection gripper 304 to rotate along the bottom of the inner slide rod 303.

[0049] The claw-like part at the bottom of the deflection gripper 304 makes inclined contact with the bottom contour area of ​​the diamond roller. With the synchronous operation of the secondary push cylinder, the slider and the inner push cylinder, the deflection gripper 304 slides upward in an inclined state, reducing the bottom contour area of ​​the diamond roller. It forms a multi-axial limiting lock with the strip support plate 501 and the arc-shaped extrusion plate 205. Combined with the weight of the diamond roller body and the subsequent continuous downward sliding of the grinding disc 402 and its pressure on the top of the diamond roller, the diamond roller body is subjected to multi-axial force coordinated limiting treatment during hole grinding.

[0050] Example 2: This example is a diamond roller grinding equipment for fine treatment of inner hole walls. It includes a lifting box 5 located at the bottom center of the conveyor plate frame 1 and below the conveyor roller 103. The lifting box 5 is provided with a strip-shaped support plate 501 that penetrates the conveyor plate frame 1 and extends through the gaps between several sets of conveyor rollers 103. A slag collection box 6 is arranged side by side on the end face of the lifting box 5.

[0051] Several sets of lifting cylinder frames 502 are symmetrically arranged on the inner walls of both sides of the lifting box 5. The lifting cylinder frames 502 are connected to both sides of the strip-shaped support plate 501. The top of the strip-shaped support plate 501 is slidably sleeved with the slot frame 104. When the diamond roller moves to the middle area above the conveyor roller 103, the conveyor roller 103 stops conveying the diamond roller. The lifting cylinder frame 502 drives the several sets of strip-shaped support plates 501 to slide upward. The top of the strip-shaped support plate 501 passes through the slot frame 104 and slides upward along the gap between the several sets of conveyor rollers 103 until the diamond roller is lifted and separated from the conveyor roller 103. During this period, the strip-shaped support plate 501 pauses briefly to cooperate with the arc-shaped extrusion plate 205 to perform secondary adjustment of the diamond roller. After the adjustment is completed, the strip-shaped support plate 501 further drives the diamond roller to slide upward and lift it to the specified height.

[0052] The slag collection box 6 has symmetrical guide grooves 601 on both sides of one end, which are connected to the slag collection trough 105. The top wall of the slag collection box 6 is equipped with an exhaust fan 602. The end of the slag collection box 6 away from the lifting box 5 is slidably connected to a slag collection box 603. The exhaust fan 602 operates during the diamond roller hole grinding. The exhaust fan 602 is connected to several sets of slag collection troughs 105 through the guide grooves 601. It is used to create a negative pressure air extraction environment in the area of ​​several sets of conveyor rollers 103 on the conveyor plate frame 1. It effectively guides the slag-containing air generated by the diamond roller hole grinding to be quickly collected into the slag collection box 603 of the slag collection box 6. The exhaust fan 602 is connected to the jet inclined plate 202 through the pipe to provide airflow pressure. The lifting brush 106 slides up synchronously to contact the bottom of the conveyor roller 103. With the rotation of the conveyor roller 103, it is used to effectively clean the impurities attached to the surface of the conveyor roller 103.

[0053] As can be seen from Embodiments 1 and 2, the diamond roller hole grinding technology has the following advantages:

[0054] • Dual-cylinder linkage positioning technology: Rotary cylinders one and two work together to form a "rotation + boost" composite power, dynamically adjusting position deviation. The non-contact design avoids damage to the rollers and is suitable for micron-level precision preprocessing.

[0055] • Dynamic synchronous lifting: The lifting cylinder frame 502 works in conjunction with the inner lifting cylinder 203. The three-stage action improves the adjustment efficiency, and the secondary adjustment corrects the offset to ensure coaxiality.

[0056] • The one-sided contact + point-contact anti-slip structure, with the arc-shaped extrusion plate 205 and the telescopic anti-slip contact rod 206 working together, improves the anti-slip coefficient and avoids scratching the roller;

[0057] • A three-dimensional limiting system with multi-axis linkage drive to deflect the 304 gripper rod forms a combination of top pressing, middle clamping, and bottom contraction limiting, improving grinding stability;

[0058] • Environmentally friendly design: The exhaust fan 602 works in conjunction with the jet baffle 202 to efficiently collect slag-containing gas and reduce dust concentration.

[0059] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
