Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting equipment technology, specifically to a cutting equipment for the production and processing of rotary joints. Background Technology
[0002] Rotary joints can be classified according to their applications into single-circuit rotary joints and double-circuit rotary joints. The connection method of a double-circuit rotary joint can be selected according to the working conditions. The inlet for the transmission medium can be freely selected from the side or rear end, depending on the working conditions. The sealing surface and sealing ring are made of special materials, which are wear-resistant, have a long service life, are corrosion-resistant, and leak-proof.
[0003] Since rotary joints are generally small in size and their surface cutting requires frequent adjustments to their position, the waste generated during cutting needs to be continuously cleaned. Manual cleaning is time-consuming, while using external mechanical equipment can easily disperse the waste, negatively impacting the work environment. Therefore, we propose a cutting device for rotary joint production and processing. Utility Model Content
[0004] The purpose of this utility model is to provide a cutting device for the production and processing of rotary joints, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a cutting device for manufacturing and processing rotary joints, comprising a workbench, a handle hinged to the upper surface of the workbench, a cover fixedly installed on the inner wall of the handle, a drive motor fixedly installed on the side wall of the cover, a cutting blade fixedly installed at the output end of the drive motor, and a chip blowing assembly provided inside the cover. The chip blowing assembly includes a drive wheel, which is coaxially and fixedly connected to the cutting blade. A driven wheel is connected to the arc-shaped outer wall of the drive wheel via a synchronous belt. A rotating wheel is coaxially and fixedly connected to the driven wheel. A protrusion is fixedly installed on the arc-shaped outer wall of the rotating wheel. An elastic airbag is fixedly installed on the inner wall of the cover. A pressure plate is fixedly connected to the top of the elastic airbag. A hose is fixedly connected to the bottom of the elastic airbag via a one-way valve. A rotating rod is rotatably installed on the inner wall of the bottom of the cover. An air blowing rod is fixedly connected to the end of the rotating rod. A coil spring is sleeved on the arc-shaped outer wall of the rotating rod. An air blowing hole is opened on the inner wall of the air blowing rod. An arc-shaped groove is opened on the inner surface of the air blowing hole.
[0006] Preferably, the diameter of the driven wheel is set to three times the diameter of the driving wheel, so that the rotational speed of the driven wheel is one-third of the rotational speed of the driving wheel, thereby allowing enough time for the elastic airbag to reset and avoiding insufficient air volume of the elastic airbag.
[0007] Preferably, the elastic airbag is provided with an elastic steel mesh inside so that the elastic airbag can have a tendency to return to its original position when compressed. Furthermore, the elastic airbag is provided with one-way valves on its side and bottom. The one-way valve on the side is a one-way air inlet valve, while the one-way valve at the bottom of the elastic airbag that connects to the hose is a one-way air outlet valve.
[0008] Preferably, the arc-shaped groove is located on the side of the air blowing hole away from the cutting blade, so that when the airflow blows into the air blowing hole, the air blowing rod will deflect slightly around the rotating rod as the rotation center due to the impact of the airflow on the arc-shaped groove.
[0009] Preferably, the inside of the cover is provided with a guide assembly, the guide assembly including an arc plate, the arc plate being movably mounted on the inner wall of the cover, an arc spring being fixedly connected between the top of the arc plate and the inner wall of the cover, and an arc groove being formed on the surface of the arc plate near the cutting blade.
[0010] Preferably, the inner wall of the cover has an arc-shaped cavity that matches the size of the arc-shaped plate, and the top end of the arc-shaped spring is fixedly connected to the top inner wall of the arc-shaped cavity.
[0011] Preferably, the arc-shaped groove is narrow in the center and wide on both sides, which can effectively collect and guide waste.
[0012] Compared with the prior art, this utility model provides a cutting device for the production and processing of rotary joints, which has the following beneficial effects: 1. The cutting equipment for manufacturing and processing rotary joints is equipped with a chip blowing assembly. The continuous rotation of the cutting blade, in conjunction with the transmission structure, intermittently compresses the elastic airbag to generate airflow. When the airflow blows into the air blowing hole, the impact of the airflow on the arc-shaped groove causes the air blowing rod to deflect slightly around the rotating rod as the rotation center. At the same time, under the elastic force of the coil spring, it swings left and right to continuously generate chip blowing airflow at the cutting position of the cutting blade, ensuring the visibility of the cutting part of the rotary joint during cutting and improving the cutting accuracy and safety.
[0013] 2. The cutting equipment for manufacturing rotary joints is equipped with a guiding component. The waste chips generated during cutting fly out along the tangent of the cutting blade and are blocked by the arc plate. The arc groove is narrow in the center and wide on both sides, which can collect and guide the waste chips. This allows the waste chips generated during the rotary joint cutting process to fall into the chip collection groove under the guidance of the arc plate, making it convenient to collect and clean them and improving the continuous processing effect of the device.

[0016] like Figures 1-6 As shown, this utility model provides a technical solution: a cutting device for manufacturing and processing rotary joints, including a workbench 1, a handle 2 hinged to the upper surface of the workbench 1, a cover 3 fixedly installed on the inner wall of the handle 2, a drive motor 4 fixedly installed on the side wall of the cover 3, a cutting blade 5 fixedly installed at the output end of the drive motor 4, and a chip blowing assembly 6 provided inside the cover 3. The chip blowing assembly 6 includes a drive wheel 61, a timing belt 62, a driven wheel 63, a rotating wheel 64, a protrusion 65, an elastic airbag 67, a pressure plate 66, a hose 68, a rotating rod 69, an air blowing rod 610, a coil spring 611, an air blowing hole 612, and an arc-shaped groove 613.
[0017] In one embodiment of this utility model, the driving wheel 61 is coaxially and fixedly connected to the cutting blade 5. The arc-shaped outer wall of the driving wheel 61 is connected to the driven wheel 63 via a synchronous belt 62. The driven wheel 63 is coaxially and fixedly connected to the rotating wheel 64. A protrusion 65 is fixedly installed on the arc-shaped outer wall of the rotating wheel 64. An elastic airbag 67 is fixedly installed on the inner wall of the cover 3. A pressure plate 66 is fixedly connected to the top of the elastic airbag 67. A hose 68 is fixedly connected to the bottom of the elastic airbag 67 via a one-way valve. A rotating rod 69 is rotatably installed on the inner wall of the bottom end of the cover 3. An air blower 610 is fixedly connected to the end of the rotating rod 69. A coil spring 611 is sleeved on the arc-shaped outer wall of the rotating rod 69. An air blower hole 612 is opened on the inner wall of the air blower 610. An arc-shaped groove 613 is opened on the inner surface of the air blower hole 612.
[0018] Furthermore, a chip collection groove is provided on the upper surface of the workbench 1, and the chip collection groove is located below the cutting blade 5 to better collect the waste chips generated during cutting. At the same time, the driving wheel 61 and the driven wheel 63 are both located on the outside of the cover 3, and the diameter of the driven wheel 63 is set to three times the diameter of the driving wheel 61, so that the rotation speed of the driven wheel 63 is one-third of the rotation speed of the driving wheel 61. This allows sufficient time for the elastic airbag 67 to reset, avoiding insufficient air volume of the elastic airbag 67, which would affect the chip blowing effect of the device. In addition, the end of the protrusion 65 is set with an arc-shaped surface, and an arc-shaped opening with a width adapted to the pressure plate 66 is provided on the side wall of the cover 3, so that the pressure plate 66 can pass through the arc-shaped opening. The exposed portion can be pushed by the rotating wheel 64 during its continuous rotation, thereby causing the pressure plate 66 to compress the elastic airbag 67. Specifically, the elastic airbag 67 has an elastic steel mesh inside, so that the elastic airbag 67 has a tendency to return to its original position when compressed. The elastic airbag 67 is provided with one-way valves on its side and bottom. The one-way valve on the side is a one-way air inlet valve, while the one-way valve at the bottom of the elastic airbag 67 that connects to the hose 68 is a one-way air outlet valve. This allows the air inside the elastic airbag 67 to be output to the hose 68 through the one-way valve at the bottom when compressed. During the return process of the elastic airbag 67, air from the external environment is drawn in through the one-way valve on the side to replenish it.
[0019] In addition, a deflection groove is provided on the inner wall of the housing 3, and the rotating rod 69 and the air blower 610 are both set in the deflection groove to avoid interference with the movement of the air blower 610. Specifically, there are two sets of rotating rods 69, air blowers 610 and coil springs 611, and the two sets of rotating rods 69, air blowers 610 and coil springs 611 are symmetrically arranged about the vertical central axis of the housing 3, so that the two sets of air blowers 610 can blow away the chips at the cutting position of the rotary joint on the left and right sides of the cutting blade 5. At the same time, the hose 68 is internally connected to the air blowing hole 612 so that the air entering the hose 68 can pass through the hole 612. The airflow in 8 can be blown out towards the surface of the cutting disc 5 through the air blowing hole 612. Furthermore, the arc-shaped groove 613 is set in the air blowing hole 612 on the side away from the cutting disc 5. When the airflow blows into the air blowing hole 612, the air blowing rod 610 will deflect slightly around the rotating rod 69 as the rotation center due to the impact of the airflow on the arc-shaped groove 613. At the same time, under the elastic force of the coil spring 611, it will swing left and right to continuously generate airflow to the cutting position of the cutting disc 5, ensuring the visibility of the cutting part of the rotary joint during cutting, and improving the cutting accuracy and safety.
[0020] Meanwhile, the inside of the cover 3 is provided with a guide component 7, which includes an arc plate 71. The arc plate 71 is movably installed on the inner wall of the cover 3. An arc spring 72 is fixedly connected between the top of the arc plate 71 and the inner wall of the cover 3. An arc groove 73 is opened on the surface of the arc plate 71 near the cutting blade 5.
[0021] In this embodiment of the utility model, the inner wall of the cover 3 is provided with an arc-shaped cavity that matches the size of the arc-shaped plate 71, and the top end of the arc-shaped spring 72 is fixedly connected to the top inner wall of the arc-shaped cavity. Under the action of gravity, the bottom end of the arc-shaped plate 71 protrudes from the cover 3 in a drooping shape, and will not detach from the arc-shaped cavity due to the restriction of the arc-shaped spring 72. When the operator holds the handle 2 and presses it down, the bottom end of the arc-shaped plate 71 is always in contact with the upper surface of the workbench 1, so as to block and protect the tangential direction of the cutting blade 5. At the same time, the arc-shaped groove 73 is set in a shape that is narrow in the center and wide on both sides, so as to collect and guide the waste chips, so that the waste chips generated during the cutting process of the rotary joint can fall into the chip collection groove under the guidance of the arc-shaped plate 71, which is convenient for collection and cleaning, and improves the continuous processing effect of the device.
[0022] In this invention, during use, the rotary joint is placed on the cutting area of the workbench 1 and fixed. Then, the motor 4 is started to drive the cutting blade 5 to rotate at high speed. At this time, the operator holds the handle 2 and presses down the cover 3 so that the edge of the cutting blade 5 contacts the surface of the rotary joint, thereby realizing the cutting operation of the rotary joint. At the same time, the continuous rotation of the cutting blade 5 drives the drive wheel 61 to rotate. Under the transmission of the synchronous belt 62, the driven wheel 63 rotates at a relatively slow speed. The rotating wheel 64 drives the protrusion 65 to intermittently press down on the pressure plate 66, so that the elastic air bag 67 continuously contracts and resets, thereby blowing air into the hose 68. Then, through the air blowing hole 612 in the air blower 610, a continuous airflow is generated at the cutting position of the cutting blade 5, ensuring the visibility of the cutting part of the rotary joint during cutting, and improving the cutting accuracy and safety.
[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
