Description

Technical Field

[0001] The present invention relates to the technical field of fixture drilling equipment for high-end equipment manufacturing, and specifically provides a fixture drilling equipment for high-end equipment manufacturing. Background Technique

[0002] Drilling is to fix the blank workpiece and use a high-speed rotating drill to process the blank to drill a through hole or blind hole of the required size. For workpieces with relatively high hardness or when the drilling speed is too high, a large amount of drill chips will be generated during the drilling process and the drill chips will fly outwards, affecting the processing environment and adding cleaning work to the operators, thus affecting the processing efficiency.

[0003] The patent with the patent announcement number CN212042724U for a fixture drilling equipment for high-end equipment manufacturing relates to a fixture drilling equipment for high-end equipment manufacturing, including a workbench, a support frame, a drilling unit and a clamping unit. Among them, the support frame includes a column, a guide rail and a lead screw. The ends of the guide rail and the lead screw are respectively connected to the column. The drilling unit includes a moving block, a first hydraulic cylinder, a servo motor and a drill bit. A first through hole and a second through hole are respectively arranged in the moving block. The guide rail passes through the first through hole, and the lead screw passes through the second through hole and is in transmission connection with the moving block. The clamping unit includes fixed seats arranged on both sides of the processing seat. A second hydraulic cylinder is fixedly connected to the fixed seat. A clamping plate is arranged at the end of the second hydraulic cylinder. A baffle is fixedly connected to the clamping plate. A semi-circular groove is opened on the baffle. The drill bit moves in the accommodating cavity formed by the semi-circular groove on the baffle under the drive of the first hydraulic cylinder to realize the drilling process of the workpiece. The provided baffle can prevent the drill chips from flying outwards and limit the drill chips in the space formed by the clamping plate and the baffle.

[0004] The drill bit of the above patent moves in the accommodating cavity formed by the semi-circular groove on the baffle under the drive of the first hydraulic cylinder to realize the drilling process of the workpiece. The provided baffle can prevent the drill chips from flying outwards and limit the drill chips in the space formed by the clamping plate and the baffle. However, the steel plate that is not fully clamped may shift during the drilling process due to the cutting force or vibration of the drill bit. This kind of movement may cause the position of the hole to be inaccurate, thereby affecting the quality and service performance of the product. If the steel plate moves, the drill bit may suffer uneven cutting loads, increasing wear or causing fracture. When the drill bit contacts the unclamped steel plate, a large lateral force may be generated, making the drill bit more vulnerable to damage. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a fixture drilling equipment for high-end equipment manufacturing, which solves the problems raised in the above background technique.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: A fixture drilling device for high-end equipment manufacturing includes a table body, on the upper surface of which a placement table is fixedly installed, a support frame is fixedly installed on the upper surface of the table body, a clamping plate is fixedly installed on the upper surface of the placement table, a rotating plate is arranged on the front side of the support frame, a lifting plate is slidably installed on the inner wall of the support frame, a telescopic rod is fixedly installed on the lower surface of the lifting plate, a drill bit is slidably installed on the lower surface of the telescopic rod, and a fixing device is also provided on the upper surface of the table body; Wherein the fixing device includes a square plate, an inclined rod, a pressing block, a first hydraulic cylinder, a first hydraulic rod, a second hydraulic cylinder, a second hydraulic rod, a pushing plate and a sliding rod. The square plate is fixedly installed on the side of the clamping plate close to the drill bit. The inclined rod is rotatably installed on the upper surface of the square plate. The pressing block is rotatably installed on the side of the inclined rod close to the drill bit. The first hydraulic cylinder is fixedly installed on the inner wall of the clamping plate. One end of the first hydraulic rod is slidably installed in the inner wall of the first hydraulic cylinder. The second hydraulic cylinder is fixedly installed on the side of the support frame close to the inclined rod. One end of the second hydraulic rod is slidably installed inside the second hydraulic cylinder. The pushing plate is fixedly installed at the other end of the second hydraulic rod. A square groove is opened on the side of the support frame close to the second hydraulic cylinder. The sliding rod is movably and slidably installed inside the square groove. After the steel plate is completely clamped, it will push the liquid inside the first hydraulic cylinder into the second hydraulic cylinder to release the limit on the lifting plate, avoiding drilling the steel plate with the drill bit when the steel plate is not tightly clamped. The steel plate that is not completely clamped may be displaced during the drilling process due to the cutting force or vibration of the drill bit. This kind of movement may cause the position of the hole to be inaccurate, thereby affecting the quality and service performance of the product.

[0007] According to the above technical solution, the other end of the first hydraulic rod is fixedly installed on the side of the square plate close to the clamping plate. A first spring is provided between the square plate and the clamping plate. The first spring is provided to avoid deforming the steel plate when clamping the steel plate. The first hydraulic cylinder and the second hydraulic cylinder are connected by a hose.

[0008] According to the above technical solution, the upper surface of the pushing plate contacts the lower surface of the sliding rod. A second square groove is opened on the side of the lifting plate close to the second hydraulic cylinder. The sliding rod slides inside the second square groove. The sliding rod slides inside the second square groove to limit the lifting plate and prevent the lifting plate from falling.

[0009] According to the above technical solution, a support device and a protection device are further provided on the upper surface of the table body. The support device includes a rack, a slide bar, a rotating shaft, an outer ring, a U-shaped rod, a square block, a cutter head and a disc. The rack is fixedly installed on the right side of the clamp. The rotating shaft is rotatably installed on the inner wall of the support table. The outer ring is slidably installed on the circumferential surface of the rotating shaft. The disc is fixedly installed at the upper end of the device. A chute is provided on the upper surface of the disc. The U-shaped rod is slidably installed inside the chute. The square block is fixedly installed on the upper surface of the U-shaped rod. The cutter head is slidably installed inside the square block. The slide bar is slidably installed on the inner wall of the table body, avoiding the deformation or warping of the steel plate caused by the cutting force of the drill bit during drilling. This deformation will affect the position and quality of the hole, resulting in eccentricity or unevenness of the hole. Due to the insufficient strength and rigidity of the thin steel plate, the phenomenon of hole wall rupture or chipping may occur during drilling, which will lead to a decline in the quality of the hole and affect subsequent processing or assembly.

[0010] A gear is fixedly installed on the outer ring. A second spring is provided between the U-shaped rod and the chute. The second spring is provided to drive the U-shaped rod back to its original position. A third spring is provided between the cutter head and the square block. The third spring is provided to push the cutter head into the drilled hole to remove the burrs inside after drilling. The outer ring is in contact with the slide bar, and the outer ring is in contact with the U-shaped rod.

[0011] According to the above technical solution, the protection device includes a baffle, an inclined head rod, a round pin, a plug pin, an inner cylinder, an outer cylinder, a vertical rod and a long rod. The baffle is slidably installed on the circumferential surface of the drill bit. The inclined head rod is fixedly installed on the upper surface of the baffle. The telescopic rod is divided into an outer cylinder and an inner cylinder. The outer cylinder is fixedly installed on the lower surface of the lifting plate. The inner cylinder is movably slidably installed on the inner wall of the outer cylinder. The drill bit is fixedly installed on the lower surface of the inner cylinder. The round pin is slidably installed on the upper surface of the drill bit. The plug pin is slidably installed on the circumferential surface of the inner cylinder. The vertical rod is fixedly installed on the upper surface of the drill bit. The long rod is slidably installed on one side of the lifting plate close to the inclined rod. The baffle protects the drill bit to avoid excessive downward pressure that may cause deformation or pits on the workpiece, affecting the quality and dimensional accuracy of the hole. This damage may cause serious problems during subsequent processing or assembly. Under high pressure, the drill bit may break due to being unable to withstand the cutting force, especially when encountering hard materials or foreign objects during drilling. The broken drill bit may cause harm to the operator.

[0012] According to the above technical solution, the upper surface of the long rod contacts the vertical rod. A fixing groove is provided on one side of the support frame close to the long rod. The size of the fixing groove matches that of the long rod. The fixing groove is provided to limit the lifting plate after the long rod enters the fixing groove. A second chute is provided on the surface of the round pin. The upper end of the inclined head rod is slidably installed inside the inner wall of the second chute. A round hole is provided on the circumferential surface of the inner cylinder. The round pin slides inside the round hole. The round hole is provided to decelerate the inner cylinder when pulling the inner cylinder.

[0013] According to the above technical solution, a deceleration groove is provided on the inner wall of the outer cylinder. The size of the deceleration groove matches that of the plug pin. A fourth spring is provided between the round pin and the inner cylinder. The fourth spring is provided to decelerate the retraction of the inner cylinder by squeezing the round pin to retract when the round pin contacts the round hole. A fifth spring is provided between the outer cylinder and the inner cylinder. The fifth spring is provided to pull the inner cylinder to retract.

[0014] The present invention provides a fixture drilling device for high-end equipment manufacturing. It has the following beneficial effects: (1) In this invention, the steel plate to be drilled is placed on the upper surface of the placement table. When the motor starts, it pushes the clamping plate to clamp the steel plate. When the clamping plate moves, it will push the square plate to move. When the square plate moves, it will clamp the steel plate. When the square plate clamps the steel plate, it will squeeze the first spring to contract. The contraction of the first spring will prevent the steel plate from being scratched. By clamping the steel plate with the square plate, after completely clamping the steel plate, it will push the liquid in the first hydraulic cylinder into the second hydraulic cylinder to release the limit on the lifting plate, avoiding drilling the steel plate with the drill bit when the steel plate is not clamped tightly. The uncompletely clamped steel plate may be displaced due to the cutting force or vibration of the drill bit during the drilling process. This kind of movement may cause the position of the hole to be inaccurate, thereby affecting the quality and service performance of the product.

[0015] (2) In this invention, when the plate moves towards the steel plate, it will push the sliding rod to move. When the sliding rod moves, it will push the outer ring to move upward. When the outer ring moves upward, it will push the U-shaped rod to slide. When the U-shaped rod slides, it will drive the square block to move. When the square block moves, it will drive the tool head to move. When the steel plate is placed on the upper surface of the placement table, it will press the tool head to move into the square block. The square block is used to lift the position on the lower surface of the steel plate that needs to be drilled, avoiding the deformation or warping of the steel plate caused by the cutting force of the drill bit during drilling. This kind of deformation will affect the position and quality of the hole, resulting in the eccentricity or unevenness of the hole. Due to the insufficient strength and rigidity of the thin steel plate, the phenomenon of hole wall cracking or chipping may occur during drilling, which will lead to the decline of the hole quality and affect the subsequent processing or assembly.

[0016] (3) In this invention, after the sliding rod releases the limit on the lifting plate, turn the handle. When the handle rotates, it will push the lifting plate to move downward. When the lifting plate moves downward, it will push the drill bit to move to punch the surface of the steel plate. When the drill bit descends to a certain distance, it will push the baffle plate to move upward. When the baffle plate moves upward, it will push the inclined head rod to move upward. The baffle plate is used to protect the drill bit to avoid excessive downward pressure that may cause the workpiece to deform or have pits, affecting the quality and dimensional accuracy of the hole. This kind of damage may cause serious damage to the workpiece during the subsequent processing or assembly process. Under high pressure, the drill bit may break due to being unable to withstand the cutting force, especially when encountering hard materials or foreign objects during drilling. The broken drill bit may cause harm to the operator. Description of the Drawings
