Description

Technical Field

[0001] The present invention relates to the technical field of burr removal, and specifically to a burr removal device for processing a pressure gauge housing. Background Art

[0002] A pressure gauge is an instrument that uses atmospheric pressure as a reference for measuring pressures greater than atmospheric pressure. It is mainly used for measuring the pressures of liquids, gases, and vapors. Most of the pressure gauges seen in daily life are elastic element type pressure gauges. Its working principle is that a sensitive element (such as a bourdon tube) produces elastic deformation under the action of pressure. The magnitude of its deformation is linearly related to the applied pressure. Through a transmission mechanism for amplification, the measured pressure is indicated by a pointer on a dial.

[0003] During the processing of a pressure gauge housing, it is necessary to remove burrs from the conduit connection holes on the pressure gauge housing. Since the external shape of the pressure gauge housing is mostly cylindrical, and the conduit connection holes are located on the cylindrical circumferential surface, therefore, when the pressure gauge housing is automatically transported and fed, the pressure gauge housing is mostly transported with the cylindrical bottom surface facing down. Designed in this way, when removing burrs from the conduit connection holes, burr waste chips will remain inside the pressure gauge housing or directly fall onto the production workshop, and need to be cleaned regularly, which is inconvenient for collecting burr waste chips and affects the actual processing efficiency. Summary of the Invention

[0004] To solve the technical problems in the background art, the present invention proposes a burr removal device for processing a pressure gauge housing.

[0005] A burr removal device for processing a pressure gauge housing proposed by the present invention includes a conveyor and a bracket. The conveyor is provided with a limiting mechanism evenly distributed along the circumferential direction of its transmission part. The upper end of the limiting mechanism has a waste chip collection tube adapted to the conduit connection holes on the housing body, and the waste chip collection tube can elastically expand and contract towards the inside of the limiting mechanism. The lower end of the waste chip collection tube is connected to a waste chip collection box. The housing body to be processed is placed on the limiting mechanism, and the conduit connection holes at the bottom of the outer circumference of the housing body are inserted into the waste chip collection tube.

[0006] The bracket is arranged above the conveyor. A working station is arranged between the conveyor and the bracket. Above the working station, a stabilizing mechanism for pressing and fastening the housing body is arranged. Below the working station, an electric push rod is arranged. The movable end of the electric push rod faces upwards and is provided with a clamp. The clamp is used to clamp the waste chip collection tube at the working station, and the electric push rod is driven to drive the clamp to drive the waste chip collection tube to move downwards so that the conduit connection holes at the bottom of the housing body are exposed.

[0007] A burr removal mechanism is provided on the side of the working station. A driving mechanism for driving the burr removal mechanism into the working station is installed on the bracket. The burr removal mechanism is used to remove the burrs of the conduit connection holes on the housing body at the working station.

[0008] As a further optimized solution of the present invention, the limiting mechanism includes a limiting seat installed on the conveying part of the conveyor. First moving holes and second moving holes are respectively opened at the upper and lower ends of the limiting seat. The first moving hole and the second moving hole communicate with each other and are centered. A spring is arranged in the first moving hole. The lower end of the waste chip collecting pipe is slidably sleeved in the first moving hole and connected to the spring. A connecting pipe is arranged inside the second moving hole. The upper end of the connecting pipe extends into the first moving hole and is communicated with the lower end of the waste chip collecting pipe. The lower end of the connecting pipe extends to the bottom of the limiting seat and is provided with a support plate for docking with the fixture.

[0009] As a further optimized solution of the present invention, the inner diameter of the first moving hole is larger than the inner diameter of the second moving hole to form an annular support surface. The spring is sleeved outside the upper end of the connecting pipe, and the upper and lower ends of the spring are respectively fixedly connected to the lower end surface of the waste chip collecting pipe and the annular support surface.

[0010] As a further optimized solution of the present invention, the conveyor is a belt conveyor, and the conveyor has two parallel conveyor belts. Both ends of the limiting seat are fixedly connected to the two conveyor belts respectively. The support plate is arranged between the two conveyor belts.

[0011] As a further optimized solution of the present invention, a groove adapted to the support plate is opened on the upper end surface of the fixture. The fixture is an electromagnet, and the support plate is made of iron. When the electric push rod drives the fixture to move upward so that the groove is assembled with the support plate, the fixture is energized to generate magnetism and adsorb the support plate to complete the docking.

[0012] As a further optimized solution of the present invention, a material guiding hole communicating with the lower end of the second moving hole is opened at the bottom of the support plate. A connecting hose is installed at the bottom of the fixture. One end of the connecting hose is connected to the material guiding hole, and the other end of the connecting hose is connected to the feed inlet of the waste chip collecting box.

[0013] As a further optimized solution of the present invention, a gasket is installed on the upper end surface of the limiting seat. The upper end surface of the gasket has an arc-shaped groove adapted to the housing body, and a sleeve hole communicating with the upper end opening of the first moving hole is opened at the center of the arc-shaped groove. The upper end of the waste chip collecting pipe penetrates through the sleeve hole and is slidably connected to the inner wall of the sleeve hole.

[0014] As a further optimized solution of the present invention, the upper end of the waste chip collecting pipe is designed with an inward concave arc shape.

[0015] As a further optimized solution of the present invention, the stabilizing mechanism includes a second cylinder and a pressing block. The second cylinder is installed at the bottom of the bracket and above the working station. The movable end of the second cylinder faces downward and is fixedly connected to the pressing block. The lower end of the pressing block has an arc-shaped groove, and the arc-shaped groove is adapted to the outer peripheral radian of the housing body.

[0016] As a further optimized solution of the present invention, the burr removing mechanism includes a baffle, a cantilever, a swing arm, and a burr file. The baffle is installed on the movable end of the driving mechanism. The cantilever is installed on one side of the baffle close to the opening of the housing body and is height-adjustable. The swing arm is installed on the free end of the cantilever and is driven by an electric motor. The burr file is installed on the free end of the swing arm and is arranged downward;

[0017] When the baffle moves under the drive of the driving mechanism and covers the opening of the housing body, the cantilever drives the swing arm and the burr file to move downward, so that the burr file is inserted into the conduit connection hole and contacts the hole wall.

[0018] The deburring device for processing the pressure gauge housing proposed by the present invention has the following beneficial effects:

[0019] In the present invention, by installing a limiting mechanism on the transmission part of the conveyor, and using the elastic telescopic design of the waste chip collection pipe at the upper end of the limiting mechanism, the housing body can be stably transmitted before deburring, preventing accidental dropping during transmission. When the housing body is transmitted to the working station, the conveyor pauses transmission. The clamp is driven by an electric push rod to move upward and clamp the lower end of the waste chip collection pipe. The waste chip collection pipe is driven by the clamp to move downward, so that the conduit connection hole of the housing body is exposed, so that the driving mechanism can drive the burr removing mechanism to move to the working station to perform burr removing operation on the conduit connection hole of the housing body. Since the housing body is in a state with the circumferential surface facing downward, the removed burr waste chips will be directly transmitted to the waste chip collection box through the conduit connection hole and the waste chip collection pipe, which is convenient for automatic collection of processing waste chips without manual regular cleaning, which is beneficial to improving the actual processing efficiency. At the same time, it can also prevent burr waste chips from staying in the housing body, thereby avoiding scratching of the inner wall of the housing body by burr waste chips, which is beneficial to improving the product quality and qualification rate of the housing body, and thus improving the production efficiency of the enterprise.

[0032] Please refer to Figures 1 - 3 , a deburring device for processing a pressure gauge housing, comprising a conveyor 1 and a bracket 2. A limiting mechanism 4 is installed on the conveyor 1 and is evenly distributed circumferentially along its transmission part. The upper end of the limiting mechanism 4 has a waste chip collecting pipe 14 adapted to the conduit connection hole on the housing body 3, and the waste chip collecting pipe 14 can elastically expand and contract towards the inside of the limiting mechanism 4. The lower end of the waste chip collecting pipe 14 is connected to a waste chip collecting box 10. The housing body 3 to be processed is placed on the limiting mechanism 4, and the conduit connection hole at the bottom of the outer periphery of the housing body 3 is inserted into the waste chip collecting pipe 14;

[0033] The bracket 2 is arranged above the conveyor 1. A working station is arranged between the conveyor 1 and the bracket 2. A stabilizing mechanism 7 for pressing and fastening the housing body 3 is arranged above the working station. An electric push rod 8 is arranged below the working station. The movable end of the electric push rod 8 faces upwards and is equipped with a clamp 9. The waste chip collecting pipe 14 at the working station is clamped by the clamp 9, and the electric push rod 8 drives the clamp 9 to drive the waste chip collecting pipe 14 to move downwards so that the conduit connection hole at the bottom of the housing body 3 is exposed;

[0034] It should be noted that the clamp 9 can be various types of clamping tools in the prior art that are applicable to this situation, such as pneumatic fingers, manipulators, or electromagnetic clamps, etc.;

[0035] A deburring mechanism 6 is arranged on the side of the working station. A driving mechanism 5 for driving the deburring mechanism 6 to enter the working station is installed on the bracket 2. The conduit connection hole of the housing body 3 at the working station is deburred by the deburring mechanism 6.

[0036] By installing a limit mechanism 4 on the conveying part of the conveyor 1 and using the elastic telescopic design of the waste chip collection pipe 14 at the upper end of the limit mechanism 4, the outer shell body 3 can be stably conveyed before deburring, preventing accidental dropping during conveyance. When the outer shell body 3 is conveyed to the working station, the conveyor 1 pauses conveyance. The electric push rod 8 is used to drive the clamp 9 to move upward and clamp the lower end of the waste chip collection pipe 14. The waste chip collection pipe 14 is driven by the clamp 9 to move downward, so that the conduit connection hole of the outer shell body 3 is exposed, so that the driving mechanism 5 drives the deburring mechanism 6 to move to the working station to perform deburring operation on the conduit connection hole of the outer shell body 3. Since the outer shell body 3 is in a state with its circumferential surface facing downward, the removed burr waste chips will be directly conveyed into the waste chip collection box 10 through the conduit connection hole and the waste chip collection pipe 14, facilitating automatic collection of the processing waste chips without manual regular cleaning, which is beneficial to improving the actual processing efficiency. At the same time, it can also prevent the burr waste chips from staying in the outer shell body 3, thereby avoiding scratching of the inner wall of the outer shell body 3 by the burr waste chips, which is beneficial to improving the product quality and qualification rate of the outer shell body 3, and thus improving the production efficiency of the enterprise.

[0037] Specifically, as Figure 3 shown, the limit mechanism 4 includes a limit seat 41 installed on the conveying part of the conveyor 1. The upper and lower ends of the limit seat 41 are respectively provided with a first moving hole 42 and a second moving hole 43. The first moving hole 42 and the second moving hole 43 communicate with each other and are arranged concentrically. A spring 45 is arranged in the first moving hole 42. The lower end of the waste chip collection pipe 14 is slidably sleeved in the first moving hole 42 and connected to the spring 45. A connecting pipe 44 is arranged inside the second moving hole 43. The upper end of the connecting pipe 44 extends into the first moving hole 42 and communicates with the lower end of the waste chip collection pipe 14. The lower end of the connecting pipe 44 extends to the bottom of the limit seat 41 and is provided with a support plate 46 for docking with the clamp 9. A material guiding hole communicating with the lower end of the second moving hole 43 is opened at the bottom of the support plate 46. A connecting hose 13 is installed at the bottom of the clamp 9. One end of the connecting hose 13 is connected to the material guiding hole, and the other end of the connecting hose 13 is connected to the feed inlet of the waste chip collection box 10;

[0038] During use, the conveyor 1 drives the limit mechanism 4 and the housing body 3 thereon to move to the working station. Then the conveyor 1 pauses operation. The upper end of the housing body 3 at the working station is clamped and positioned by the stabilizing mechanism 7 to keep the housing body 3 stable. Then the electric push rod 8 drives the fixture 9 to move upward so that the fixture 9 completes the clamping docking with the pallet 46. Then the electric push rod 8 drives the fixture 9 and the pallet 46 to move downward. The pallet 46 drives the connecting pipe 44 and the waste chip collecting pipe 14 to move downward. The waste chip collecting pipe 14 slides downward along the inner wall of the first moving hole 42, and the spring 45 is squeezed by the waste chip collecting pipe 14 and is in a compressed state. When the upper end of the waste chip collecting pipe 14 completely disengages from the conduit connection hole of the housing body 3, the electric push rod 8 pauses driving so that the waste chip collecting pipe 14 remains at a constant height. Then the driving mechanism 5 drives the burr removing mechanism 6 to move to the working station. The burr removing mechanism 6 removes burrs from the conduit connection hole. The removed burr waste chips converge downward under the influence of the inner arc surface of the housing body 3 and its own weight and fall into the waste chip collecting pipe 14. The waste chip collecting pipe 14 conducts the waste chips through the connecting pipe 44 and the material guiding holes of the pallet 46 into the connecting hose 13, and then the connecting hose 13 transports the waste chips to the waste chip collecting box 10 for collection. After the burrs of a single housing body 3 are removed, the fixture 9 releases the docking with the pallet 46, and the spring 45 loses the external force traction and returns to its original state, so that the connecting pipe 44 and the waste chip collecting pipe 14 move upward and reset. The waste chip collecting pipe 14 is inserted into the conduit connection hole of the housing body 3 again. The stabilizing mechanism 7 moves upward and resets, and the bracket 2 resumes operation, thus realizing the automatic feeding and burr removing operation of the housing body 3;

[0039] Further, as Figure 3 shown, the inner diameter of the first moving hole 42 is larger than the inner diameter of the second moving hole 43 to form an annular support surface. The spring 45 is sleeved outside the upper end of the connecting pipe 44, and the upper and lower ends of the spring 45 are fixedly connected to the lower end surface of the waste chip collecting pipe 14 and the annular support surface respectively, which can improve the elastic deformation stability of the spring 45, thereby improving the elastic retraction and extension stability of the waste chip collecting pipe 14;

[0040] Further, as Figure 2 shown, the conveyor 1 is a belt conveyor, and the conveyor 1 has two parallel conveyor belts. The two ends of the limit seat 41 are respectively fixedly connected to the two conveyor belts. The pallet 46 is arranged between the two conveyor belts;

[0041] It should be noted that the number of the limit mechanisms 4 is odd, and the distance between two adjacent limit mechanisms 4 is equal. When the limit mechanism 4 located above the conveyor belt moves to the working station, there is no obstacle between the working station below and the electric push rod 8. With such a design, it will not affect the synchronous lifting of the electric push rod 8 driving the fixture 9 and the connecting hose 13, so as to ensure the normal operation of the equipment;

[0042] Specifically, as Figure 3 shown, the upper end face of the fixture 9 is provided with a groove adapted to the pallet 46. The fixture 9 is an electromagnet, and the pallet 46 is made of iron. When the electric push rod 8 drives the fixture 9 to move upward so that the groove is assembled with the pallet 46, the fixture 9 is energized to generate magnetism and adsorb the pallet 46 to complete the docking. Through the electromagnetic adsorption design, the clamping and docking of the pallet 46 can be completed quickly and accurately, and it can also be released. Of course, a manipulator or other automated fixtures can also be used;

[0043] Furthermore, the pallet 46 can also be a magnet, and the magnetism of this magnet is opposite to that of the electrified fixture 9. When the fixture 9 is energized to generate magnetism, it can be better magnetically fixed with the pallet 46.

[0044] Specifically, as Figure 3 shown, a gasket 47 is installed on the upper end face of the limit seat 41. The upper end face of the gasket 47 has an arc-shaped groove adapted to the housing body 3. The design of the arc-shaped groove can improve the stability of the housing body 3 placed on the gasket 47, and a sleeve hole communicating with the upper opening of the first moving hole 42 is opened at the center of the arc-shaped groove. The upper end of the waste chip collecting pipe 14 passes through the sleeve hole and is slidably connected to the inner wall of the sleeve hole, which is beneficial to improving the placement stability of the housing body 3;

[0045] Furthermore, a protective plate can be installed above the conveyor belt of the conveyor 1. The number of the protective plates is two and they are arranged oppositely to form a channel for transporting the housing body 3, which is beneficial to improving the stability of the housing body 3 when it is transported onto the conveyor 1;

[0046] Furthermore, the protective plate on the side close to the burr removal mechanism 6 is provided with an opening. The opening is on the side of the working station, and the diameter of the opening is larger than the width of the burr removal mechanism 6 to ensure that the burr removal mechanism 6 can enter and exit the working station smoothly.

[0047] Specifically, as Figure 3 shown, the upper end of the waste chip collecting pipe 14 is designed with an inward concave arc, which is convenient for guiding the burr waste chips to the center to improve the automatic collection effect of the waste chips.

[0048] Specifically, as Figure 2 and 4 shown, the stabilizing mechanism 7 includes a second cylinder 71 and a pressing block 72. The second cylinder 71 is installed at the bottom of the bracket 2 and above the working station. The movable end of the second cylinder 71 faces downward and is fixedly connected to the pressing block 72. The lower end of the pressing block 72 has an arc-shaped groove, and the arc-shaped groove is adapted to the outer peripheral radian of the housing body 3. By driving the pressing block 72 to move downward through the second cylinder 71, the arc-shaped groove of the pressing block 72 presses on the upper end face of the housing body 3 at the working station to improve the placement stability of the housing body 3, and further improve the burr removal stability of the subsequent burr removal mechanism 6.

[0049] Specifically, as Figure 5 shown, the burr removal mechanism 6 includes a baffle 61, a cantilever 62, a swing arm 63, and a burr file 64. The baffle 61 is installed on the movable end of the driving mechanism 5. The cantilever 62 is installed on one side of the baffle 61 close to the opening of the housing body 3 and its height is adjustable. The swing arm 63 is installed on the free end of the cantilever 62 and is driven by an electric motor. The burr file 64 is installed on the free end of the swing arm 63 and is arranged downward;

[0050] When the baffle 61 moves under the driving action of the driving mechanism 5 and covers the opening of the housing body 3, the cantilever 62 drives the swing arm 63 and the burr file 64 to move downward, so that the burr file 64 is inserted into the conduit connection hole and contacts the hole wall. The swing arm 63 is driven to rotate by an electric motor, thereby driving the burr file 64 to perform a circumferential movement along the hole wall of the conduit connection hole, so as to complete the burr removal operation on the inner wall of the conduit connection hole;

[0051] Further, a lifting mechanism 65 is installed on one side of the baffle 61 close to the opening of the housing body 3. One end of the cantilever 62 away from the swing arm 63 is slidably connected to the baffle 61, and the cantilever 62 is connected to the movable end of the lifting mechanism 65. By driving the cantilever 62 to lift and lower through the lifting mechanism 65, the heights of the swing arm 63 and the burr file 64 can be adjusted, so as to insert or remove the burr file 64 from the conduit connection hole;

[0052] Further, a vertically arranged strip-shaped groove is formed on one side of the baffle 61 close to the opening of the housing body 3. One end of the cantilever 62 is slidably arranged in the strip-shaped groove. The lifting mechanism 65 is an electric screw structure, and the cantilever 62 is fixed to the movable end of the electric screw. By operating the electric screw, the cantilever 62 can be driven to lift and lower;

[0053] Further, a sealing ring 66 is installed on one side of the baffle 61 close to the opening of the housing body 3. The sealing ring 66 is adapted to the inner diameter of the opening of the housing body 3. When the baffle 61 covers the opening of the housing body 3, the sealing ring 66 is inserted into the interior of the housing body 3, and the outer wall of the sealing ring 66 is in close fit with the inner wall of the opening of the housing body 3, thereby ensuring the sealing of the opening of the housing body 3;

[0054] Further, in order to improve the waste chip collection efficiency, an air jet pipe 11 is also installed on one side of the baffle 61 close to the opening of the connecting hose 13. A downwardly arranged air jet nozzle is installed at one end of the air jet pipe 11. The other end of the air jet pipe 11 extends to the other side of the baffle 61 and is connected to an external air blowing device through an air supply pipe 12. After the burr removal is completed, air is blown into the housing body 3 through the air blowing device, so that the airflow entrains the residual waste chips in the housing body 3 and discharges them through the conduit connection hole, which is beneficial to improving the actual waste chip cleaning effect, avoiding residual waste chips in the housing body 3, and is beneficial to improving the product qualification rate.

[0055] Specifically, as Figure 2 and Figure 4 shown, the driving mechanism 5 includes a first cylinder 51 and a suspension rod 52. The first cylinder 51 is installed on the bracket 2, and the pushing direction of the first cylinder 51 is perpendicular to the conveying direction of the conveyor 1. The movable end of the first cylinder 51 extends to the side of the bracket 2 and is connected to the upper end of the suspension rod 52. The lower end of the suspension rod 52 extends downward to the side of the working station and is connected to the burr removal mechanism 6. By driving the suspension rod 52 to move with the first cylinder 51, the burr removal mechanism 6 can be driven to enter and exit the working station;

[0056] Furthermore, a groove 53 adapted to the suspension rod 52 is provided on one side of the bracket 2 close to the suspension rod 52. When the first cylinder 51 drives the suspension rod 52 to drive the burr removal mechanism 6 to move to the working station, the suspension rod 52 moves into the groove 53 and fits against the inner wall of the groove 53, which can ensure that the burr removal mechanism 6 accurately enters the working station and improve the actual processing accuracy;

[0057] It should be noted that an inductive switch can be installed inside the groove 53. When the suspension rod 52 enters the groove 53 and triggers the inductive switch, the first cylinder 51 pauses. After a certain period of time, after the burr removal mechanism 6 finishes machining the conduit connection hole of the housing body 3, the first cylinder 51 drives the suspension rod 52 to move out and reset. The control of the above electrical components can be adjusted through the existing PLC or single-chip microcomputer control system, so the principle and specific circuit thereof will not be elaborated herein.

[0058] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
