Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy parts processing technology, specifically to an automatic deburring device for the top and bottom surfaces of powder metallurgy parts. Background Technology

[0002] Powder metallurgy is a method of manufacturing metal parts. It involves pressing metal powder into a mold and then sintering it to form the part. During this process, factors such as the fit gap between the molds and uneven pressure distribution during pressing may cause burrs to form on the part part's parting surface. These burrs not only affect the appearance quality of the parts but may also adversely affect subsequent assembly and use, and may even cause functional problems. For some precision applications or products with strict surface finish requirements, customers usually do not allow any burrs to exist. Therefore, burr removal has become one of the important post-processing steps in the production of powder metallurgy parts.

[0003] Traditional manual deburring methods, such as sanding or cleaning with a copper wire brush, can remove burrs to some extent, but these methods are inefficient and rely on the operator's experience and skill level, making them prone to human error. For example, over-deburring can cause chipping at the edges of parts, which directly affects the mass production and quality stability of the product. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic deburring device for the upper and lower surfaces of powder metallurgy parts, comprising an operating table and a feeding conveyor and a discharging conveyor installed on the operating table, and a lower drive motor installed between the feeding conveyor and the discharging conveyor, wherein a lower copper wire brush is fixed to the drive end of the lower drive motor.

[0005] A stand is fixed on the surface of the operating table. A lead screw device is installed on one side of the stand. A lifting frame is fixed at the moving end of the lead screw device. An upper drive motor is installed on the lifting frame. An upper copper wire brush is fixed at the driving end of the upper drive motor. A magnetic disk opposite to the upper copper wire brush is installed on the feeding conveyor.

[0006] An adjustment component is also installed on the operating table. The moving end of the adjustment component is fixed to a housing. An inner plate is fixed inside the housing. A lifting part is installed on the inner plate. A magnetic suction cup is installed at the bottom of the lifting part.

[0007] Furthermore, the bottom of the lifting frame is fixed with a cover box that covers the upper copper wire brush inside, and the bottom of the cover box is completely open.

[0008] Furthermore, the front and rear sides of the cover extend downwards and form transverse edges in opposite directions.

[0009] Furthermore, a vacuum pump is installed on the lower platform of the operating table, and two sets of upper plates are installed on the upright frame. The upper plates are equipped with upper pipes that are connected to the vacuum pump. Lower pipes are installed on both the left and right sides of the cover box, and the lower pipes are connected to the corresponding upper pipes through telescopic flexible hoses.

[0010] Furthermore, a platform cover is fixed on the operating table to cover the lower copper wire brush on the inside, and the top of the platform cover is completely open.

[0011] Furthermore, the front and rear sides of the platform cover extend upwards, and two platform pipes are fixed at the bottom, which pass through the operating table and are connected to the dust pump.

[0012] Furthermore, the adjustment assembly includes a lead screw traverse device, and a lead screw lifting device is installed at the moving end of the lead screw traverse device. The housing is fixed to the moving end of the lead screw lifting device.

[0013] Furthermore, the lifting unit includes a pressing cylinder mounted on the inner plate and multiple guide rods passing through it. The piston rod of the pressing cylinder and the guide rods are both connected to the magnetic chuck.

[0014] Furthermore, two sets of through-beam photoelectric sensors are installed on the feeding conveyor platform, located on the left and right sides of the magnetic disk respectively, and through-beam photoelectric sensors are also installed at the head end of the unloading conveyor platform.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] This automatic deburring equipment for powder metallurgy parts automates part transfer via an upper and lower conveyor, reducing manual intervention. A magnetic disk is used to adsorb parts, ensuring stable part position during the deburring process on the top surface of the part driven by the upper drive motor and the upper copper wire brush. An adjustment component and lifting unit adsorb the parts, and the lower drive motor drives the lower copper wire brush to rotate, thus deburring the bottom surface of the part. This allows for automated deburring of both sides, significantly increasing output per unit time. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This embodiment of an automatic deburring device for the top and bottom surfaces of powder metallurgy parts includes an operating table 1 with a feeding conveyor 2 and a discharging conveyor 25 installed at its two ends. A magnetic disk 4 is installed on the feeding conveyor 2. A stand 5 is also fixed on the operating table 1 near the feeding conveyor 2. A lead screw device 8 is installed on the front of the stand 5. A lifting frame 9 is fixed at the moving end of the lead screw device 8. An upper drive motor 10 is installed on the top of the lifting frame 9. The driving end of the upper drive motor 10 extends to the bottom of the lifting frame 9 and is fixed with an upper copper wire brush 17 that is perpendicular and symmetrical to the magnetic disk 4. A lower drive motor 15 and an adjustment component are installed at the bottom of the operating table 1 between the feeding conveyor 2 and the discharging conveyor 25. A lower copper wire brush 16 is fixed at the rotating end of the lower drive motor 15. A housing 20 is fixed at the moving end of the adjustment component. An inner plate 21 is fixed inside the housing 20. A lifting part is installed on the inner plate 21. A magnetic chuck 24 is installed at the bottom end of the lifting part.

[0024] In the above structure, the parts are conveyed to the magnetic disk by the feeding conveyor and fixed. Then, the lead screw device drives the lifting frame to move down to the designated position, so that the upper copper wire brush comes into contact with the product. The upper drive motor drives the removal of burrs on the top of the product. After the removal is completed, the feeding conveyor conveys the product to the tail end. Then, the adjusting component works with the lifting part to drive the magnetic chuck to attract the product. The product is then moved to be in contact with the lower copper wire brush, and the lower drive motor drives the removal of burrs on the bottom of the product. Then, the lifting part retracts, and the distance between the magnetic chuck and the part increases, so that the product is placed on the unloading conveyor and transported away. This can realize the automated removal of burrs on both the top and bottom, thus effectively improving efficiency.

[0025] The lifting frame 9 has a cover box 11 fixed at its bottom to house the upper copper wire brush 17, and the operating table 1 has a table cover 13 fixed at its top to house the lower copper wire brush 16. Both the top of the table cover 13 and the bottom of the cover box 11 are completely open. Therefore, during the deburring process, the table cover and the cover box can prevent burr fragments from flying, thus effectively avoiding injury to workers and inconvenience in cleaning.

[0026] Meanwhile, two sets of through-beam photoelectric sensors 3 are installed on the surface of the loading conveyor 2, located on the left and right sides of the magnetic disk 4 respectively, and through-beam photoelectric sensors 3 are also installed at the head of the unloading conveyor 25. The through-beam photoelectric sensors sense the position of the product and work in conjunction with the operation of the loading and unloading conveyors to complete the deburring and conveying.

[0027] To further explain, the front and rear plates of the cover box 11 extend downwards, and a raised edge is formed on the opposite side of the bottom of the two plates. The front and rear plates of the platform cover 13 extend upwards. Therefore, when the lifting frame moves down, the bottom of the cover box will contact the feeding conveyor table. Because of the raised edge, its support strength is improved, and it can limit the descent of the cover box and the copper wire brush to a suitable position. At the same time, the extended long side of the platform cover guides the box and also more effectively prevents burrs from splashing.

[0028] Further explanation: A vacuum pump 26 is installed on the lower part of the operating table 1. Two upper plates 6 are fixed to the top of the support frame 5, and upper pipes 7 connected to the vacuum pump 26 are installed on the upper plates 6. Lower pipes 12 connected to the corresponding upper pipes 7 via external telescopic hoses are fixed to the left and right sides of the cover box 11. Two platform pipes 14 are fixed to the bottom of the platform cover 13, each passing through the operating table 1 and connected to the vacuum pump 26. Therefore, with the action of the telescopic hoses, the raising and lowering of the lower pipes can be unimpeded. During the deburring process, the upper pipes, telescopic hoses, lower pipes, and platform pipes can work together to absorb and remove the generated burrs, dust, and harmful gases.

[0029] Additionally, the adjustment assembly includes a lead screw traversing device 18 mounted on the table, with a lead screw lifting device 19 installed at the moving end of the lead screw traversing device 18. The housing 20 is fixed to the moving end of the lead screw lifting device 19. The lead screw traversing device can move the housing above the loading and unloading conveyor table, while the lead screw lifting device can move the housing closer to the loading and unloading conveyor table to complete the picking and placing of products.

[0030] Further explanation: The lifting unit includes a pressing cylinder 22 mounted on the inner plate 21 and connected to the magnetic chuck 24, and four guide rods 23 passing through and also connected to the magnetic chuck 24. The guide rods improve the stability of the magnetic chuck's lifting and lowering, while the pressing cylinder drives the magnetic chuck to come close to the bottom of the housing, thus enabling the parts to be attracted through the housing. After processing, the bottom of the housing moves to a suitable position on the unloading conveyor table, and then the pressing cylinder drives the magnetic chuck to move upward, thereby separating the magnetic chuck from the parts, allowing the parts to be placed on the unloading conveyor table and sent away.

[0031] The working principle of the above embodiments is as follows:

[0032] The parts are conveyed via a feeding conveyor, passing through a through-beam photoelectric sensor and moved above a magnetic disk. Simultaneously, the feeding conveyor stops, the magnetic disk holds the parts in place, and the lead screw mechanism moves, lowering the lifting plate until the cover covers the product. The upper drive motor and dust pump are activated, driving the upper copper wire brush to remove burrs. Simultaneously, the upper and lower tubes and the telescopic hose work together to attract any remaining burrs or other impurities. After cleaning, the magnetic disk releases, the feeding conveyor starts moving, and the parts are moved to the end of the feeding conveyor. The lead screw lateral movement and lifting mechanism move the lower part of the box to contact the parts. Then, a downward-pressing cylinder moves the magnetic suction cup to contact the bottom of the box, attracting the parts. The parts are then moved to the position opposite the lower copper wire brush, where the lower drive motor cleans the lower part, and the platform tube also performs its attraction function. After processing, the parts are moved to the unloading conveyor. The downward-pressing cylinder then moves the magnetic suction cup back, placing the parts on the unloading conveyor for transport.
