Description

Technical Field

[0001] The invention relates to the technical field of automobile bushing processing, in particular to a bushing necking processing device. Background Art

[0002] During the manufacturing process of automobile bushings, especially after necking (i.e., the process of reducing the inner diameter of the bushing), oil immersion treatment is usually required. The oil immersion treatment can improve the performance of the automobile bushings.

[0003] The existing equipment has the following technical defects during use: (1) When the existing equipment performs oil immersion treatment on the automobile bushing, it is generally placed in direct contact with the bottom wall of the oil tank. The automobile bushing directly contacts the bottom wall of the container and is easily contaminated by impurities or sediments on the bottom wall of the container. These pollutants are likely to affect the performance of the automobile bushing, and thus easily reduce the production quality of the equipment's automobile bushing; (2) Before the existing equipment performs oil immersion treatment on the automobile bushing, the bubbles in the oil are not pre-treated, which will affect the fluidity and continuity of the oil, thereby affecting the sealing effect of the bushing, and making it inconvenient for the equipment to meet the use needs of the staff. Summary of the invention

[0004] The object of the present invention is to provide a bushing necking processing device.

[0005] The technical problems solved by the present invention are: (1) the existing equipment does not place the automobile bushing in the air when immersing the automobile bushing in oil, which makes it easy for the automobile bushing to be contaminated by impurities or sediments on the bottom wall of the container; (2) the existing equipment does not pre-treat the bubbles in the oil before immersing the automobile bushing in oil, which makes it easy for the bubbles to affect the quality of the automobile bushing.

[0006] The present invention can be implemented through the following technical scheme: a bushing necking treatment device, comprising an oil tank fixed to a workbench, and a bushing transplanting mechanism on the workbench, the bushing transplanting mechanism is used to transport and transfer the automobile bushing after it is immersed in oil, a material guide conveying plate is fixedly installed on one side of the oil tank, and the tail end of the material guide conveying plate corresponds to the product box, the bushing transplanting mechanism comprises a moving plate horizontally slidably connected to the workbench, a hydraulic cylinder is fixedly installed on the top of the moving plate, and the output end of the hydraulic cylinder is rotatably connected to a porous containing boat, and the inner cavity of the porous containing boat is penetrated and provided with at least one placement slot for placing the automobile bushing in the air; the porous containing boat is driven by the hydraulic cylinder to enter the oil tank, thereby facilitating the oil immersion treatment of the automobile bushing;

[0007] The inner cavity of the oil tank is provided with a bubble elimination mechanism, which includes a sliding plate vertically elastically slidably connected to the inner cavity of the oil tank. The inner cavity of the sliding plate is provided with a plurality of connecting holes for bubbles to pass through, and the connecting holes are used to filter bubbles in the oil.

[0008] A further technical improvement of the present invention is that both the top wall and the bottom wall of the sliding plate are provided with trumpet holes connected to the connecting hole, and the arrangement of the trumpet holes makes it easier for bubbles in the oil to enter the connecting hole.

[0009] A further technical improvement of the present invention is that: the inner cavity of the sliding plate is provided with two inner grooves which are staggered on both sides of the connecting hole, and the inner cavity of the inner groove is horizontally elastically slidably connected with a sharp knife for puncturing bubbles.

[0010] A further technical improvement of the present invention is that a bushing drying assembly is arranged on the movable plate, and the bushing drying assembly includes a drying fan fixed on the movable plate, and a drying nozzle group connected to the drying fan is fixedly installed on the bottom end of the movable plate. The drying fan is driven through the drying nozzle group to accelerate the drying of the automobile bushing, thereby facilitating the acceleration of the overall production progress of the equipment and facilitating use.

[0011] A further technical improvement of the present invention is that a cleaning assembly is provided in the inner cavity of the porous containing boat, and the cleaning assembly includes a scraper which is horizontally slidably connected to the inner cavity of the porous containing boat and abuts against its inner bottom wall. Discharge channels which cooperate with the scraper are penetrated through the bottom ends of both sides of the porous containing boat. The horizontally sliding scraper allows the waste on the inner bottom wall of the porous containing boat to be discharged through the discharge channel.

[0012] A further technical improvement of the present invention is that receiving drawers for receiving waste materials in the discharge channel are arranged on both sides of the porous containing boat.

[0013] A further technical improvement of the present invention is that the inner cavity of the porous containing ship is also provided with a driving member that enables the scraper to slide back and forth horizontally in the inner cavity of the porous containing ship. The driving member includes a screw rod rotatably connected to the inner cavity of the porous containing ship, and a threaded sleeve on the outer peripheral wall of the screw rod is provided with a sliding sleeve fixed to the scraper. The rotating screw rod causes the sliding sleeve to drive the scraper to slide back and forth horizontally.

[0014] A further technical improvement of the present invention is that a reciprocating motion component is arranged on the workbench to enable the movable plate to slide back and forth horizontally. The reciprocating motion component includes a threaded rod rotatably connected to the workbench. A threaded sleeve on the outer peripheral wall of the threaded rod is provided with a screw sleeve fixed to the movable plate. The screw sleeve is horizontally slidably connected to the workbench. The threaded rod is rotated to cause the screw sleeve to drive the movable plate to slide back and forth horizontally.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention places the automobile bushing after necking in the porous containing boat through a manipulator, and places the automobile bushing horizontally when placing the automobile bushing. By opening a placement groove in the inner cavity of the porous containing boat, it is convenient to guide the manipulator to place the automobile bushing in the air. The automobile bushing is placed in the air to ensure that all parts of the automobile bushing can fully contact the oil, avoid partial areas being blocked and not fully infiltrated, and reduce the probability of the automobile bushing being contaminated by impurities or sediments at the bottom of the container, thereby ensuring the production quality of the automobile bushing and facilitating the use of the staff.

[0017] 2. The present invention causes the sliding plate to move downward synchronously as the automobile bushing enters the oil in the oil tank. The movement of the sliding plate allows the bubbles in the oil to pass through the trumpet holes and the connecting holes therein in sequence. When the bubbles pass through the connecting holes, a sharp knife arranged in the inner cavity thereof is used to puncture the bubbles. Pre-treatment of the bubbles in the oil can ensure uniform distribution of the oil, better fill the gap between the automobile bushing and the shaft, improve the sealing performance, and thereby enable the equipment to meet the use requirements of the staff.

By driving the drying fan 412, wind can be blown toward the automobile bushing through the drying nozzle group 413, thereby accelerating the drying of the automobile bushing and facilitating subsequent use.

[0040] The inner cavity of the oil tank 2 is provided with a bubble elimination mechanism, which includes a sliding plate 21 vertically slidably connected between the two inner side walls of the oil tank 2. The inner cavity of the sliding plate 21 is provided with a plurality of connecting holes 22 for the bubbles in the oil liquid to pass through. The top wall and the bottom wall of the sliding plate 21 are both provided with trumpet holes 23 connected with the connecting holes 22. The trumpet holes 23 are provided to facilitate the bubbles to better enter the inner cavity of the connecting holes 22.

[0042] When the present invention is used, the necked automobile bushing is placed in the porous containing boat 410 (wherein the number of automobile bushings is at least one) by a manipulator, and the automobile bushing is placed horizontally when placed. A placement groove 411 is provided in the inner cavity of the porous containing boat 410 to facilitate guiding the manipulator to place the automobile bushing in the air. The placement of the automobile bushing in the air facilitates ensuring that all parts of the automobile bushing can fully contact the oil, avoiding failure to fully infiltrate due to partial area being blocked, and reducing the probability of the automobile bushing being contaminated by impurities or sediments at the bottom of the container;

[0043] After placement, the power of the driving motor 44 is turned on to rotate the threaded rod 41, and the screw sleeve 42 slides horizontally through the rotation of the threaded rod 41. The horizontal sliding of the screw sleeve 42 moves the automobile bushing in the porous containing boat 410 to the top of the oil tank 2. When it moves to the top of the oil tank 2, the power of the driving motor 44 is cut off first, and then the hydraulic cylinder 45 is driven. The lifting bracket 46 is driven downward by the hydraulic cylinder 45. The automobile bushing in the porous containing boat 410 connected to the inner cavity of the lifting bracket 46 can be completely immersed in the oil of the oil tank 2 by the downward movement of the lifting bracket 46. After the oil immersion of the automobile bushing is completed, the porous containing boat 410 can be reset by driving the hydraulic cylinder 45.

[0044] As the porous containment boat 410 moves downward, the sliding plate 21 is pushed downward synchronously. The movement of the sliding plate 21 allows the bubbles in the oil to pass through the trumpet holes 23 and the connecting holes 22 therein in turn. When the bubbles pass through the connecting holes 22, the sharp knife 25 provided in the inner cavity of the connecting holes 22 facilitates the bubbles to be punctured. By pre-treating the bubbles in the oil, the oil can be evenly distributed, the gap between the automobile bushing and the shaft can be better filled, and the sealing performance can be improved.

[0045] After the porous receiving boat 410 is reset, the porous structure in the porous receiving boat 410 facilitates the oil draining of the automobile bushing, and the driving of the drying fan 412 facilitates the drying of the automobile bushing. Drying the automobile bushing is not only conducive to accelerating the production progress of the equipment, but also prevents the oil on the automobile bushing from contaminating the material conveying plate 3;

[0046] After the automobile bushing is dried, the automobile bushing is moved to the front end of the material guide conveying plate 3 by the driving motor 44, and the dried automobile bushing is conveniently transferred to the material guide conveying plate 3 by the driving of the servo motor 47, and is conveniently conveyed to the corresponding product box by the material guide conveying plate 3, so as to facilitate the subsequent processing by the staff.

[0047] After the processing of the automobile bushing is completed, the porous containing boat 410 can be selectively cleaned according to its usage. When it needs to be cleaned, the handle 54 is turned to rotate the screw rod 52. The rotation of the screw rod 52 drives the sliding sleeve 53 to drive the scraper 51 to clean the inner bottom wall of the porous containing boat 410. The cleaned waste enters the receiving drawer 55 through the discharge channel. The receiving drawer 55 is convenient for collecting the waste. Pulling out the receiving drawer 55 facilitates timely cleaning of the waste. Regular cleaning of the porous containing boat 410 facilitates the long-term use of the equipment, thereby facilitating the use needs of the staff.
