Description

Technical Field

[0001] The present invention relates to the technical field of high-pressure pump part processing, and particularly relates to a clamping tooling for milling processing of high-pressure pump parts. Background Art

[0002] A high-pressure pump is a device that provides high-pressure power for high-pressure rotary jet grouting cement slurry, and is used for foundation strengthening and reinforcement in construction, roads, etc. It can also be used for high-pressure water jet-assisted rock breaking and coal falling, underground hydraulic support liquid supply, pumping high-pressure water for water-expanded metal anchor bolts for anchoring, and dredging, cleaning, and washing of large underground pipelines. The milling processing procedure steps of the high-pressure pump pump head include: positioning and clamping, rough milling of the outer shape, fine milling of details, and drilling treatment. These steps ensure that the size, shape, and precision of the pump head parts meet the requirements. In the milling processing of the high-pressure pump pump head, each procedure step is crucial. The positioning and clamping need to ensure that the pump head parts are stable without shaking. When rough milling the outer shape, excess material needs to be removed. Fine milling of details pursues high-precision dimensions and shapes, and drilling treatment is to meet the specific functional requirements of the pump head. In addition, during the milling processing, attention also needs to be paid to the selection of cutting tools, the setting of cutting parameters, and the use of coolant, and these factors will directly affect the processing quality and efficiency. In the existing technology for processing stainless steel pump heads, each surface of the steel block needs to be processed, and it takes about 6 hours to process one pump head. At the same time, during the processing, manual flipping of the steel block is required to achieve processing of different surfaces.

[0003] The invention patent with the application publication number CN118893488A discloses a milling device and process for a water pump shaft. The rotating cleaning mechanism includes a protective shell, and a milling device body is arranged on the side of the protective shell. A blocking and protecting mechanism is arranged on the top of the milling device body. When the fixed scraper and the rotating scraper move away from the outer shell of the milling device, they are cleaned, thereby prolonging the service life of the fixed scraper and the rotating scraper. At the same time, by rotating the adjusting rod and the buckle around the fixed column, the buckle can be engaged with the card slot opened on the outer ring surface of the fixed disc, so that milling cutters of different sizes can be adapted, reducing the production cost. This invention adjusts the milling cutter to increase the processing surface of the workpiece, but the bottom still cannot be processed. Summary of the Invention

[0004] The purpose of the present invention is to provide a clamping tooling for milling processing of high-pressure pump parts, which can achieve the effect of comprehensively processing the workpiece, and can realize the flipping and milling process of the workpiece without manual operation.

[0005] The above technical object of the present invention is achieved by the following technical solutions: A clamping tooling for milling machining of high-pressure pump parts, including a milling machine tool and an operating table. The following are provided on the operating table: A clamping mechanism, which includes a clamping frame, a bracket provided on the clamping frame, two clamping arms provided on the bracket, a clamping driving member for driving the clamping arms to approach or move away from each other, and a rotation driving member for controlling the rotation of the two clamping arms; A fixing mechanism, which includes two fixing plates and a fixing driving member for driving the two fixing plates to approach or move away from each other; A control member, a control member is provided between the clamping mechanism and the fixing mechanism.

[0006] By adopting the above technical solutions, after the single-sided machining of the steel block is completed, the effect of automatic turning can be achieved. The operator places the steel block on the operating table, and the milling machine tool processes it. After the single-sided machining is completed, the clamping mechanism clamps it, and then the rotation driving member drives it to rotate, and then places it on the operating table, and the fixing mechanism clamps and fixes it, and the milling machine tool continues to perform milling machining. This method can realize the automatic turning operation of the workpiece.

[0007] The further setting of the present invention is: The clamping driving member includes a screw rod, a clamping control gear, and a clamping motor. The clamping control gear is coaxially and fixedly connected to the middle of the screw rod. Positive threads and reverse threads are respectively provided on both sides of the screw rod. The two clamping arms are respectively threadedly connected to both sides of the screw rod through the positive thread and the reverse thread. The clamping motor drives the clamping control gear to control the rotation of the screw rod, thereby driving the two clamping arms to approach or move away from each other.

[0008] The further setting of the present invention is: The rotation driving member includes a rotation motor and a rotation rod. The rotation rod is rotatably connected to the clamping frame. The bracket is fixedly connected to the end of the rotation rod. The rotation motor is provided on the clamping frame. The rotation motor drives the rotation rod to rotate to control the rotation of the bracket. A synchronizing member is provided between the rotation driving member and the clamping driving member.

[0009] A further setting of the present invention is that the synchronizing member includes a driving rod, a driving worm gear, a driving worm, a synchronizing rod, and a synchronizing gear. The driving rod is rotatably arranged on the clamping frame, the output end of the rotating motor is coaxially and fixedly connected to the driving rod, the driving worm is coaxially and fixedly arranged on the driving rod, the synchronizing rod is rotatably connected to the clamping frame, the synchronizing rod is perpendicular to the driving rod, the driving worm gear is coaxially and fixedly connected to the synchronizing rod, the driving worm gear is engaged with the driving worm, the synchronizing gear is coaxially and fixedly connected to the synchronizing rod, a cylindrical rack is slidably sleeved outside the rotating rod, and the synchronizing gear is engaged with the cylindrical rack.

[0010] A further setting of the present invention is that a rotating plate is arranged on the clamping arm, the two rotating plates are respectively rotatably arranged on the two clamping arms relatively, a flipping motor is further arranged on the clamping arm, the output end of the flipping motor is fixedly connected to the rotating plate, and the flipping motor drives the rotating plate to rotate.

[0011] A further setting of the present invention is that the fixed driving member includes two fixed frames slidably connected to the operating table, a sector gear rotatably connected to the operating table, sliding racks are arranged on the two fixed frames, the two sliding racks are respectively engaged with the two sector gears, two fixing plates are respectively vertically and fixedly connected to the two fixed frames, and the synchronizing member drives the two sector gears to rotate synchronously.

[0012] A further setting of the present invention is that the control member includes a driving motor, a driving lead screw, a control rod, and a synchronizing connecting rod. The driving motor is arranged on the operating table, the driving lead screw is rotatably connected to the operating table, the clamping frame is threadedly connected to the driving lead screw, the control rod is fixedly connected to the side of the clamping frame close to the fixing mechanism, a synchronizing arm is horizontally arranged at the end of the control rod, and the two ends of the synchronizing connecting rod are respectively rotatably connected between the synchronizing arm and the sector gear.

[0013] By adopting the above technical solution, when the single-sided machining is completed and flipping is required, the driving motor will control the driving screw rod to rotate. When the driving screw rod rotates, it will drive the clamping frame to approach the workpiece. During the forward movement of the clamping frame, the control rod will drive the sector gear to rotate through the synchronous arm and synchronous connecting rod. During the rotation of the two sector gears, they will drive the sliding racks to move away from each other, further driving the fixing plates on the fixed frame to move away from each other, so as to limit the contact with the workpiece. At the same time, when the clamping arms are located on both sides of the workpiece, the clamping motor will drive the driving rod to rotate. The driving rod drives the driving worm wheel to rotate through the driving worm, and the driving worm wheel drives the synchronous gear to rotate through the synchronous rod. The synchronous gear meshes with the cylindrical rack, and the cylindrical rack will move axially along the rotating rod, driving the clamping control gear to rotate. The clamping control gear is coaxially and fixedly connected to the screw rod, and the clamping control gear will drive the screw rod to rotate. When the screw rod rotates, since square threads and reverse threads with opposite spiral directions are arranged on both sides of the screw rod, therefore, the two clamping arms threadedly connected to the screw rod will approach each other to clamp the workpiece. At this time, the rotating click will control the rotating rod to rotate. The rotating rod is fixedly connected to the bracket, and the clamping arms are slidably connected to the bracket. Therefore, the rotating rod will drive the two clamping arms to rotate through the bracket, thereby driving the workpiece to flip. After the workpiece flips, the clamping mechanism will retract. When the clamping mechanism retracts, the clamping frame will drive the sector gear to rotate through the synchronous rod, driving the two fixing plates to approach each other to clamp the workpiece in the middle.

[0014] A further setting of the present invention is that: a lifting table is arranged on the operating table, and a lifting driving member is arranged below the lifting table.

[0015] A further setting of the present invention is that: the lifting driving member includes a lifting plate, a lifting groove, and a push rod. The lifting plate is vertically slidably arranged on the operating table. The lifting table is horizontally arranged above the lifting plate. The lifting plate is provided with a lifting groove. The push rod is arranged on the clamping frame, and the end of the push rod is provided with an insertion rod, and the insertion rod is slidably inserted into the lifting groove.

[0016] A further setting of the present invention is that: the height of the lifting groove on the side close to the clamping frame is higher than the height of the side of the lifting groove far from the clamping frame.

[0017] By adopting the above technical solution, a lifting driving member is arranged in the present invention. The lifting driving member can move synchronously with the clamping mechanism. When the clamping mechanism approaches the workpiece, the lifting driving member will drive the lifting table to rise and lift the workpiece, facilitating the clamping and flipping of the workpiece. When the clamping mechanism retracts, the lifting table descends to be flush with the operating table, facilitating the milling process.

[0018] When the clamping frame approaches the workpiece, the inserting rod on the push rod moves on the lifting groove. At this time, the fixed plate first unlocks the clamping of the workpiece, and the clamping frame continues to move. The inserting rod on the push rod moves to the end. Limited by the lifting groove, the inserting rod drives the lifting platform to move upward through the lifting plate. When it moves to the upper end, the clamping driving part drives the clamping arm to clamp the workpiece. The clamping frame continues to move forward, so that the workpiece is separated from the lifting platform. Then, the rotation driving part controls the workpiece to rotate. After the rotation is completed, the clamping frame moves back, so that the workpiece moves onto the lifting plate. When continuing to move, the lifting plate moves downward to be parallel to the operating platform. At the same time, when continuing to move, the two fixed plates approach each other to realize the clamping effect on the workpiece.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. After the single-sided machining of the steel block is completed, the effect of automatic turning over can be achieved. The operator places the steel block on the operating platform, and the milling machine processes it. After the single-sided machining is completed, the clamping mechanism clamps it, and then the rotation driving part drives it to rotate, and then it is placed on the operating platform, and the fixing mechanism clamps and fixes it. The milling machine continues to perform milling machining. This method can realize the automatic turning-over operation of the workpiece.

[0021] 2. In the present invention, a lifting driving part is provided. The lifting driving part can move synchronously with the clamping mechanism. When the clamping mechanism approaches the workpiece, the lifting driving part drives the lifting platform to rise, jacking up the workpiece, which is convenient for clamping and flipping the workpiece. When the clamping mechanism retracts, the lifting platform descends to be flush with the operating platform, which is convenient for the milling process.

[0022] 3. When the clamping frame approaches the workpiece, the inserting rod on the push rod moves on the lifting groove. At this time, the fixed plate first unlocks the clamping of the workpiece, and the clamping frame continues to move. The inserting rod on the push rod moves to the end. Limited by the lifting groove, the inserting rod drives the lifting platform to move upward through the lifting plate. When it moves to the upper end, the clamping driving part drives the clamping arm to clamp the workpiece. The clamping frame continues to move forward, so that the workpiece is separated from the lifting platform. Then, the rotation driving part controls the workpiece to rotate. After the rotation is completed, the clamping frame moves back, so that the workpiece moves onto the lifting plate. When continuing to move, the lifting plate moves downward to be parallel to the operating platform. At the same time, when continuing to move, the two fixed plates approach each other to realize the clamping effect on the workpiece. Description of the Drawings

[0033] Embodiment, as Figure 1 , Figure 2 , Figure 3As shown in the figure, a clamping tooling for milling of high-pressure pump parts includes a milling machine 1 and an operating table 2.

A control member 5 is provided between the clamping mechanism 3 and the fixing mechanism 4. When the clamping mechanism 3 approaches or separates from the fixing mechanism 4, the control member 5 drives the two fixing plates 41 on the fixing mechanism 4 to separate from or approach each other.

[0034] After the single-sided machining of the steel block is completed, the effect of automatic turning can be achieved. The operator places the steel block on the operating table 2, and the milling machine 1 processes it. After the single-sided machining is completed, the clamping mechanism 3 clamps it, and then the rotation driving member drives it to rotate, and then places it on the operating table 2. The fixing mechanism 4 clamps and fixes it, and the milling machine 1 continues the milling process. This method can achieve the automatic turning operation of the workpiece.

[0035] As Figure 3 、 Figure 4 、 Figure 5 shown, the clamping driving member includes a screw 34, a clamping control gear 35, and a clamping motor 36. The clamping control gear is coaxially and fixedly connected to the middle of the screw 34. Positive threads and reverse threads are respectively provided on both sides of the screw 34. The two clamping arms 33 are respectively threadedly connected to both sides of the screw 34 through the positive threads and reverse threads. The clamping motor 36 drives the clamping control gear 35 to control the rotation of the screw 34, thereby driving the two clamping arms 33 to approach or separate from each other.

[0036] As Figure 3 、 Figure 4 、 Figure 5 shown, the rotation driving member includes a rotation motor 37 and a rotation rod 38. The rotation rod 38 is rotatably connected to the clamping frame 31. The bracket 32 is fixedly connected to the end of the rotation rod 38. The rotation motor 37 is provided on the clamping frame 31. The rotation motor 37 drives the rotation rod 38 to rotate to control the rotation of the bracket 32. A synchronizing member 39 is provided between the rotation driving member and the clamping driving member.

[0037] As Figure 3 、 Figure 4 、 Figure 5As shown, the synchronizing member 39 includes a driving rod 391, a driving worm gear 392, a driving worm 393, a synchronizing rod 394, and a synchronizing gear 395. The driving rod 391 is rotatably arranged on the clamping frame 31. The output end of the rotating motor 37 is coaxially and fixedly connected to the driving rod 391. The driving worm 393 is coaxially and fixedly arranged on the driving rod 391. The synchronizing rod 394 is rotatably connected to the clamping frame 31. The synchronizing rod 394 is perpendicular to the driving rod 391. The driving worm gear 392 is coaxially and fixedly connected to the synchronizing rod 394. The driving worm gear 392 cooperates with the driving worm 393. The synchronizing gear 395 is coaxially and fixedly connected to the synchronizing rod 394. A cylindrical rack 396 is sleeved outside the rotating rod 38 in a sliding manner. The synchronizing gear 395 meshes with the cylindrical rack 396.

[0038] As Figure 3 , Figure 4 , Figure 5 As shown, a rotating plate 331 is arranged on the clamping arm 33. The two rotating plates 331 are respectively rotatably arranged on the two clamping arms 33. A flipping motor 332 is further arranged on the clamping arm 33. The output end of the flipping motor 332 is fixedly connected to the rotating plate 331. The flipping motor 332 drives the rotating plate 331 to rotate.

[0039] As Figure 3 , Figure 6 As shown, the fixed driving member includes two fixed frames 42 slidably connected to the operating table 2 and a sector gear 43 rotatably connected to the operating table 2. Sliding racks 421 are arranged on the two fixed frames 42. The two sliding racks 421 respectively mesh with the two sector gears 43. Two fixing plates 41 are respectively vertically and fixedly connected to the two fixed frames 42. The synchronizing member 39 drives the two sector gears 43 to rotate synchronously.

[0040] As Figure 3 , Figure 6 As shown, the control member 5 includes a driving motor 51, a driving lead screw 52, a control rod 53, and a synchronizing link 54. The driving motor 51 is arranged on the operating table 2. The driving lead screw 52 is rotatably connected to the operating table 2. The clamping frame 31 is threadedly connected to the driving lead screw 52. The control rod 53 is fixedly connected to the side of the clamping frame 31 close to the fixing mechanism 4. A synchronizing arm 531 is horizontally arranged at the end of the control rod 53. The two ends of the synchronizing link 54 are respectively rotatably connected between the synchronizing arm 531 and the sector gear 43.

[0041] When flipping is required after single-sided processing is completed, the drive motor 51 will control the drive lead screw 52 to rotate. When the drive lead screw 52 rotates, it will drive the clamping frame 31 to approach the workpiece. During the forward movement of the clamping frame 31, the control rod 53 will drive the sector gear 43 to rotate through the synchronizing arm 531 and the synchronizing link 54. During the rotation of the two sector gears 43, the sliding racks 421 will move away from each other, further driving the fixing plates 41 on the fixing frame 42 to move away from each other, so as to limit the contact with the workpiece. At the same time, when the clamping arms 33 are located on both sides of the workpiece, the clamping motor 36 will drive the drive rod 391 to rotate. The drive rod 391 drives the drive worm wheel 392 to rotate through the drive worm 393. The drive worm wheel 392 drives the synchronizing gear 395 to rotate through the synchronizing rod 394. The synchronizing gear 395 meshes with the cylindrical rack 396. The cylindrical rack 396 will move axially along the rotating rod 38, driving the clamping control gear 35 to rotate. The clamping control gear 35 is coaxially and fixedly connected to the screw rod 34. The clamping control gear 35 will drive the screw rod 34 to rotate. When the screw rod 34 rotates, since square threads and reverse threads with opposite spiral directions are provided on both sides of the screw rod 34, the two clamping arms 33 threadedly connected to the screw rod 34 will approach each other to clamp the workpiece. At this time, the rotation click will control the rotating rod 38 to rotate. The rotating rod 38 is fixedly connected to the bracket 32, and the clamping arm 33 is slidably connected to the bracket 32. Therefore, the rotating rod 38 will drive the two clamping arms 33 to rotate through the bracket 32, thereby driving the workpiece to flip. After the workpiece flips, the clamping mechanism 3 will retract. When the clamping mechanism 3 retracts, the clamping frame 31 will drive the sector gear 43 to rotate through the synchronizing rod 394, driving the two fixing plates 41 to approach each other to clamp the workpiece in the center.

[0042] As Figure 6 、 Figure 7 shown, a lifting table 6 is provided on the operating table 2, and a lifting driving member is provided below the lifting table 6.

[0043] As Figure 6 、 Figure 7 shown, the lifting driving member includes a lifting plate 61, a lifting groove 62, and a push rod 63. The lifting plate 61 is vertically slidably arranged on the operating table 2. The lifting table 6 is horizontally arranged above the lifting plate 61. The lifting plate 61 is provided with a lifting groove 62. The push rod 63 is arranged on the clamping frame 31. The end of the push rod 63 is provided with an insertion rod 631, and the insertion rod 631 is slidably inserted into the lifting groove 62.

[0044] As Figure 6 、 Figure 7 shown, the height of the lifting groove 62 on the side close to the clamping frame 31 is higher than the height of the lifting groove 62 on the side far from the clamping frame 31.

[0045] In the present invention, a lifting driving member is provided. The lifting driving member can move synchronously with the clamping mechanism 3. When the clamping mechanism 3 approaches the workpiece, the lifting driving member will drive the lifting table 6 to rise and lift the workpiece, facilitating the clamping and flipping of the workpiece. When the clamping mechanism 3 retracts, the lifting table 6 descends to be flush with the operation table 2, facilitating the milling process.

[0046] When the clamping frame 31 approaches the workpiece, the insertion rod 631 on the push rod 63 moves on the lifting groove 62. At this time, the fixing plate 41 first unlocks the clamping of the workpiece. The clamping frame 31 continues to move. The insertion rod 631 on the push rod 63 moves to the end. Limited by the lifting groove 62, the insertion rod 631 will drive the lifting table 6 to move upward through the lifting plate 61. When it moves to the upper end, the clamping driving member drives the clamping arm 33 to clamp the workpiece. The clamping frame 31 continues to move forward. After the workpiece is separated from the lifting table 6, the rotation driving member controls the workpiece to rotate. After the rotation is completed, the clamping frame 31 moves back, making the workpiece move onto the lifting plate 61. When continuing to move, the lifting plate 61 will move downward to be parallel to the operation table 2. At the same time, when continuing to move, the two fixing plates 41 approach each other to achieve the clamping effect on the workpiece.
