Description

Technical Field

[0001] The present invention relates to the technical field of pipeline through-hole processing, and specifically to a rubber-lined pipeline through-hole processing device for a general-purpose machine tool. Background Art

[0002] A rubber-lined pipeline is a special pipeline system, and its main feature is that the inner wall of the pipeline is lined with one or more layers of rubber materials. This design aims to improve the corrosion resistance, wear resistance and sealing performance of the pipeline. The rubber lining can adapt to different working environments, including extreme conditions such as chemical corrosion, high temperature, low temperature and high pressure. These pipelines are widely used in industries such as chemical engineering, petroleum, food, medicine, water treatment, etc. for transporting various media. By coating rubber on the inner surface of a metal or other substrate pipeline, the rubber-lined pipeline not only enhances the service life of the pipeline, but also provides good chemical resistance and impact resistance.

[0003] The rubber-lined pipeline through-hole processing device fixes the rubber-lined pipeline to be processed on the machine tool to ensure its stability, and adjusts the position and parameters of the drill bit according to the design requirements, such as rotational speed, feed speed and pressure. After starting the device, the drill bit starts to drill the pipeline surface under the drive of power. After the processing is completed, the device is stopped, the drill bit is taken out, and the size and position of the hole are checked to see if they meet the specification requirements, so as to ensure the accuracy of the rubber-lined pipeline through-hole processing.

[0004] During the use of the current device, there are still inconveniences: The processing of the through-hole of the rubber-lined pipeline usually requires extremely high accuracy for subsequent assembly and use. And before drilling, the drill bit needs to be level with the pipeline axis. Due to the different sizes of the pipelines, the height of the drill bit needs to be adjusted frequently. The process is cumbersome and the manual adjustment accuracy is not high, which results in the drill bit not being aligned with the pipeline axis, and the drilling will deviate from the predetermined position, resulting in inaccurate hole positions and affecting the subsequent assembly and use of the pipeline.

[0018] Beneficial Effects

[0019] The universal rubber-lined pipe through-hole processing equipment for machine tools provided by the present invention has the following beneficial effects:

[0020] 1. Through the coordinated use of the rubber lined pipe and the movable clamp, when the height of the drilling drill bit needs to be adjusted to meet the height of the drill bit and the pipe axis, the rubber lined pipe is completely clamped by two pushing slides. At this time, the adjustment slide is located at the axis of the rubber lined pipe. In this process, the drilling drill bit is driven to slide inside the outer frame through the connecting mechanism, so as to realize the alignment of the drilling drill bit and the axis of the rubber lined pipe. Therefore, ensuring the alignment of the drill bit and the pipe axis can ensure the accuracy of the hole position, reduce processing errors, and improve product quality.

[0021] 2. By pushing the slide plate and the fan together, the fan is driven to rotate through the transmission mechanism, and the airflow flows inside the ventilation slot, thereby forming a negative pressure inside the collection box, so that the dust inside the connecting pipe is sucked into the collection box for centralized collection. Centralized dust collection can significantly reduce the dust in the working area, improve the breathing environment of the operator, and prevent dust and fine particles from entering the equipment, causing equipment wear, failure or reduced accuracy.

[0022] 3. Through the combined use of the collection box and the collision rod, as more and more dust falls into the movable box, the pushing rod on the surface drives the second gear to rotate. Since the contact plate extends into the adjacent teeth of the second gear surface, the rotation of the second gear drives the collision rod to swing back and forth under the action of the thrust given to the contact plate surface and the gravity of the collision rod itself, so as to repeatedly collide with the bell, thereby emitting an alarm externally, reminding the operator to clean the dust collector in time, avoiding excessive dust from affecting the equipment performance and causing dust backflow, helping to keep the equipment clean and operating normally, and thus extending the service life of the equipment.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Reference Figures 1 to 7 , a through-hole processing device for a rubber-lined pipe of a general-purpose machine tool according to a preferred embodiment of the present invention will be described in detail below. A through-hole processing device for a rubber-lined pipe of a general-purpose machine tool includes a general-purpose machine tool 1. A rubber-lined pipe 2 is provided on the surface of the general-purpose machine tool 1. An outer frame 3 is movably connected to one side of the general-purpose machine tool 1. An electric slide rail is provided between the outer frame 3 and the side wall of the machine tool 1. The electric slide rail drives the outer frame 3 to move on the surface of the machine tool 1. A drilling bit 4 is provided on the inner wall of the outer frame 3. The drilling bit 4 is attached with any driving member or a combination thereof that can be understood by those skilled in the art such as a motor, so no further elaboration will be made here. An active fixture 513 for positioning the axis of the rubber-lined pipe 2 is provided inside the outer frame 3. An adjustment slide plate 511 and a push slide plate 512 for adjusting the position of the drilling bit 4 are provided inside the outer frame 3;

[0034] A dust suction frame 611 for preventing dust from scattering is provided inside the outer frame 3. A collection box 615 for centrally collecting dust is provided inside the outer frame 3. A fan 613 and an active push block 617 for sucking dust into the collection box 615 through negative pressure are provided inside the outer frame 3;

[0035] An active box 712 for checking the weight of dust inside the collection box 615 is provided inside the outer frame 3.

[0036] Such as Figure 2 In, the outer adjustment slide plate 511 is slidably connected to the inside of the outer frame 3. The active fixture 513 is movably connected to one side of the outer frame 3. The active fixture 513 is slidably connected to the inside of the adjustment slide plate 511. An adjustment groove 515 is provided on the surface of the active fixture 513. Such as Figure 5Among them, a central push shaft 514 is provided on one end surface of the movable fixture 513. The central push shaft 514 is slidably connected inside the adjustment groove 515 on the surface of the movable fixture 513. When it is necessary to adjust the height of the drilling bit 4 to make the drill bit and the pipeline axis at the same height, an electric telescopic rod is provided inside the outer frame 3. The movable fixture 513 is pushed to slide through the movable rod, and then a force towards the center of the adjustment slide plate 511 is given to the two movable fixtures 513 through the central push shaft 514. When one of the two movable fixtures 513 first contacts the surface of the rubber-lined pipeline 2, the movable fixture 513 that first contacts the rubber-lined pipeline 2 cannot slide. Thus, the force is transmitted to the surface of the adjustment slide plate 511 through the push slide plate 512, driving the adjustment slide plate 511 to slide towards the movable fixture 513 that first contacts the rubber-lined pipeline 2 until the two push slide plates 512 completely clamp the rubber-lined pipeline 2. At this time, the adjustment slide plate 511 is located at the axis of the rubber-lined pipeline 2. During this process, the drilling bit 4 is driven to slide inside the outer frame 3 through the connection mechanism, so as to align the axis of the drilling bit 4 with that of the rubber-lined pipeline 2, ensuring that the alignment of the drill bit and the pipeline axis can guarantee the accuracy of the hole position, reduce the processing error, and improve the product quality.

[0037] As Figure 4 Among them, a movable push block 617 is provided on the surface of the push slide plate 512. An active rack 612 and a fixed abutment block 618 are provided inside the sliding path of the movable push block 617. The active rack 612 and the fixed abutment block 618 are not in the same horizontal plane. A first gear 614 is provided inside the outer frame 3. The first gear 614 meshes with the active rack 612. As Figure 6In the embodiment, the collecting box 615 is arranged inside the outer frame 3, the dust collecting frame 611 is slidably connected to the surface of the drilling bit 4, a connecting pipe 616 is arranged between the dust collecting frame 611 and the collecting box 615, the fan 613 is connected to the No. 1 gear 614 through a transmission mechanism, a ventilation slot is arranged between the fan 613 and the collecting box 615, a dust outlet slot is arranged on the surface of the drilling bit 4, and the dust outlet slot on the surface of the drilling bit 4 is communicated with the connecting pipe 616, and the surface of one end of the dust collecting frame 611 is arranged in an arc shape, and the movable gear rod 612 is driven to slide synchronously with the push slide 512 in the direction of the drilling bit 4 driven by the telescopic rod, and when the drilling bit 4 is aligned, the drilling bit 4 is driven by the telescopic rod to drill a hole on the surface of the rubber lined pipe 2, and at this time, the dust collecting frame 611 contacts the surface of the rubber lined pipe 2, and the drilling The dust discharged is guided to the inside of the connecting pipe 616 through the dust suction frame 611 along the dust outlet groove. At the same time, the sliding plate 512 is pushed to contact the inclined surface of the fixed stop block 618, thereby contracting. At this time, the movable gear rod 612 loses the limit of the movable push block 617, and slides in the direction away from the drilling drill bit 4 under the action of the spring, thereby driving the No. 1 gear 614 to rotate, and driving the fan 613 to rotate through the transmission mechanism, and the air flow flows inside the ventilation groove, thereby forming a negative pressure inside the collection box 615, so that the dust inside the connecting pipe 616 is sucked into the collection box 615 for centralized collection. Centralized dust collection can significantly reduce the dust in the working area, improve the breathing environment of the operator, and prevent dust and fine particles from entering the equipment, causing equipment wear, failure or reduced accuracy.

[0038] like Figure 7 In the embodiment, the movable box 712 is slidably connected to the inside of the collection box 615, the surface of the movable box 712 is provided with a connecting slide shaft 713, the connecting slide shaft 713 slides with the surface of the collection box 615, a power gear rod 714 is provided in the sliding path of the connecting slide shaft 713, a rebound block 716 is provided in the sliding path of the power gear rod 714, the rebound block 716 and the connecting slide shaft 713 are not located in the same horizontal plane, a No. 1 spring 715 is provided at one end of the power gear rod 714, a No. 3 gear 7112 is provided inside the outer frame 3, the No. 3 gear 7112 is meshed with the power gear rod 714, and a No. 2 gear is provided on the surface of the No. 3 gear 7112 717, the surface of the third gear 7112 is provided with a push rod 718 and a rebound pick 719. As more and more dust falls into the movable box 712, the movable box 712 slides downward, and drives the power gear rod 714 to slide downward through the connecting slide shaft 713. When the weight inside the movable box 712 reaches a certain critical value, the power gear rod 714 contacts the inclined surface of the rebound block 716. At this time, the inclined surface of the power gear rod 714 shrinks, and the power gear rod 714 loses the restriction of the connecting slide shaft 713. The power gear rod 714 slides upward driven by the first spring 715, thereby driving the third gear 7112 to rotate. Figure 7Among them, a clamping groove is provided on the inner wall of the second gear 717. One end of the pushing rod 718 extends into the clamping groove. The collision rod 7111 is rotatably connected inside the outer frame 3. A contact plate 7110 is provided on the surface of the collision rod 7111. The contact plate 7110 extends into the inner part of the adjacent tooth blocks on the surface of the second gear 717. The bell 711 is arranged inside the rotation path of one end of the contact plate 7110. The inclined surfaces are provided at one end of the elastic return block 716 and the power tooth rod 714. The inclined surface of the elastic return block 716 is in fit with the inclined surface of the power tooth rod 714. And the second gear 717 is driven to rotate by the pushing rod 718 on the surface. Since the contact plate 7110 extends into the inner part of the adjacent tooth blocks on the surface of the second gear 717, the rotation of the second gear 717 drives the collision rod 7111 to swing back and forth under the action of the thrust given to the surface of the contact plate 7110 and the self-gravity of the collision rod 7111, so as to repeatedly collide with the bell 711, thereby sending out an alarm externally, reminding the operator to clean the dust collector in time, avoiding excessive dust from affecting the equipment performance and causing dust backflow, helping to keep the equipment clean and running normally, and thus prolonging the service life of the equipment.

[0039] The following is the entire working process and principle of the above embodiment: When it is necessary to adjust the height of the drilling bit 4 to make it equal to the axis of the pipeline, an electric telescopic rod is provided inside the outer frame 3. The movable clamp 513 is pushed to slide through the movable rod, and then a force towards the center of the adjustment slide plate 511 is applied to the two movable clamps 513 through the central push shaft 514. When one of the two movable clamps 513 first touches the surface of the rubber-lined pipeline 2, the movable clamp 513 that first touches the rubber-lined pipeline 2 cannot slide. Thus, the force is transmitted to the surface of the adjustment slide plate 511 through the push slide plate 512, driving the adjustment slide plate 511 to slide towards the movable clamp 513 that first touches the rubber-lined pipeline 2 until the two push slide plates 512 completely clamp the rubber-lined pipeline 2. At this time, the adjustment slide plate 511 is located at the axis of the rubber-lined pipeline 2. During this process, the drilling bit 4 is driven to slide inside the outer frame 3 through the connection mechanism, so as to align the axis of the drilling bit 4 with that of the rubber-lined pipeline 2, ensuring that the alignment of the drill bit and the pipeline axis can guarantee the accuracy of the hole position, reduce processing errors, and improve product quality. As the push slide plate 512 slides towards the drilling bit 4 driven by the telescopic rod, the movable rack 612 slides synchronously. When the drilling bit 4 is aligned, the drilling bit 4 is driven by the telescopic rod to drill on the surface of the rubber-lined pipeline 2. At this time, the dust suction frame 611 contacts the surface of the rubber-lined pipeline 2, and the drilled dust is guided into the interior of the connecting pipe 616 through the dust outlet groove by the dust suction frame 611. At the same time, the push slide plate 512 contacts the inclined surface of the fixed abutting block 618 and contracts. At this time, the movable rack 612 loses the limit of the movable push block 617 and slides away from the drilling bit 4 under the action of the spring, driving the first gear 614 to rotate, and driving the fan 613 to rotate through the transmission mechanism. The air flows inside the ventilation groove, forming a negative pressure inside the collection box 615, sucking the dust inside the connecting pipe 616 into the collection box 615 for centralized collection. Centralized collection of dust can significantly reduce the dust in the working area, improve the breathing environment of the operators, and prevent dust and fine particles from entering the equipment, resulting in equipment wear, failure, or accuracy decline. As more and more dust falls into the movable box 712, the movable box 712 slides downward, and drives the power rack 714 to slide downward through the connecting slide shaft 713. When the weight inside the movable box 712 reaches a certain critical value, the power rack 714 contacts the inclined surface of the resilient abutting block 716. At this time, the inclined surface of the power rack 714 contracts, and the power rack 714 loses the restriction of the connecting slide shaft 713. The power rack 714 slides upward under the drive of the first spring 715, driving the third gear 7112 to rotate, and driving the second gear 717 to rotate through the surface push rod 718. Since the contact plate 7110 extends into the adjacent tooth blocks on the surface of the second gear 717,The second gear 717 rotates, so as to drive the collision rod 7111 to swing back and forth under the action of the thrust given to the surface of the contact plate 7110 and the self-gravity of the collision rod 7111, so as to repeatedly collide with the bell 711, thereby giving an alarm externally, reminding the operator to clean the dust collector in time, avoiding excessive dust from affecting the equipment performance and causing dust backflow, helping to keep the equipment clean and running normally, and thus extending the service life of the equipment.
