Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy product processing technology, specifically to a chamfering device for powder metallurgy automotive parts. Background Technology

[0002] Powder metallurgy is a process technology that uses metal powders (or mixtures of metal and non-metal powders) as raw materials, and through forming and sintering, manufactures metallic materials, composite materials, and various types of products. For example, in the manufacturing of automotive parts such as gears, chamfering is an important process aimed at reducing noise during gear meshing, improving meshing accuracy, reducing meshing impact, and extending gear life. It also facilitates gear heat treatment and assembly. A search revealed Chinese patent application number "CN202323083746.7", which discloses a gear chamfering machine. This machine includes a base, a processing table fixedly mounted on the base, a rotating rod rotatably mounted on the processing table, a rotating disk fixedly mounted at one end of the rotating rod, a cavity inside the rotating disk, and multiple slotted holes on the surface of the rotating disk. An I-beam is slidably mounted in each slotted hole, a top block is fixedly mounted on the surface of the I-beam, a threaded rod is rotatably mounted in the cavity, and a transmission component for driving the I-beam to slide is provided within the cavity. This invention utilizes the cooperation of a threaded rod, an I-beam block, a top block, and a transmission assembly to quickly fix the gear to be processed at the axial position of the rotating disk.

[0003] However, existing technologies have the following problems: During the beveling process, the grinding wheel of the beveling machine generates a lot of heat when it rotates at high speed and rubs against the workpiece. If the heat is not dissipated in time, it may cause the workpiece to burn or deform, or even affect the internal structure of the material (such as the hardness of steel decreasing due to overheating), which reduces the quality of the workpiece and also reduces the service life of the grinding wheel.

[0004] Therefore, the present invention urgently needs to solve the problem of providing a chamfering device for powder metallurgy automotive parts that can simultaneously chamfer both ends of automotive parts of different sizes during use, thereby improving its working efficiency, and can also cool down the grinding wheel of the grinding machine and the gears of the automotive parts during the chamfering process, thereby extending the service life of the grinding wheel and avoiding affecting the quality of the gears of the automotive parts. Utility Model Content

[0005] To address the aforementioned technical problems, the purpose of this utility model is to overcome the issue that in the prior art, during the chamfering process, the grinding wheel of the chamfering machine generates a large amount of heat due to friction with the workpiece during high-speed rotation. If heat is not dissipated in time, it may cause the workpiece to burn or deform, and even affect the internal structure of the material, reducing the quality of the workpiece and shortening the service life of the grinding wheel. Therefore, this utility model provides a chamfering device for powder metallurgy automotive parts that can simultaneously chamfer both ends of automotive parts of different sizes, improving its working efficiency. Furthermore, during the chamfering process, it can cool the grinding wheel of the grinding machine and the gears of the automotive parts, thereby extending the service life of the grinding wheel and preventing any impact on the quality of the automotive parts' gears.

[0006] To achieve the above objectives, this utility model provides a chamfering device for powder metallurgy automotive parts. The device includes: a cabinet, a rotating platform horizontally and rotatably disposed within the cabinet, two movable seats respectively disposed on both sides of the rotating platform and adjustable in both height and spacing, two grinding wheels respectively disposed on the ends of the two rotating platforms for chamfering automotive parts, and a cooling mechanism. The cooling mechanism includes: a nozzle, a cooling box, a No. 1 water pump, and a No. 2 water pump; wherein... Each of the movable seats located above the grinding wheel is equipped with at least one nozzle tilted downwards towards the rotary table. The bottom of the cabinet is integrally formed with a water storage chamber communicating with its interior. The cooling box, capable of cooling inside, is horizontally arranged next to the water storage chamber. A first water pump with its outlet connected to the cooling box is fixedly installed in the water storage chamber. A second water pump is fixed on the outer wall of the water storage chamber. The inlet of the second water pump is connected to the interior of the cooling box through a circulation pipe, and its outlet is connected to the two nozzles respectively through water pipes.

[0007] Preferably, the cooling mechanism further includes: a semiconductor cooler; wherein, The side wall of the refrigeration box is equipped with a number of semiconductor coolers, and the cooling surface of each semiconductor cooler is either against the side wall of the refrigeration box or located inside the refrigeration box.

[0008] Preferably, the inlet end of the second water pump is also connected to a fixed water supply pipe, and the circulation pipe and the water supply pipe are respectively fixedly equipped with switch valves.

[0009] Preferably, the device further includes a multi-dimensional adjustment mechanism capable of adjusting both the height of the two movable seats and the distance between them, the multi-dimensional adjustment mechanism comprising: a linear module and a worm gear screw jack; wherein, Linear modules are horizontally fixedly installed at the bottom of the cabinets on both sides of the rotating platform. Each linear module has a fixed seat fixedly installed on its slider. Each fixed seat has a worm gear screw jack vertically fixedly installed on its seat. Each worm gear screw jack has a movable seat horizontally fixedly installed on its nut.

[0010] Preferably, the upper end of the rotary table is horizontally fixed with a clamp for holding and fixing automotive parts, and the clamp is a three-jaw chuck.

[0011] Preferably, a window communicating with the interior is provided on one side of the cabinet, and transparent door panels are movably provided on the side walls of the cabinet on both sides of the window in the horizontal direction, which can be abutted together to block the window.

[0012] Preferably, the bottom of the cabinet is provided with discharge holes that communicate with its interior.

[0013] Preferably, a first liquid level sensor and a second liquid level sensor are fixedly installed inside the water storage chamber and the refrigeration box, respectively.

[0014] Preferably, two support plates are fixedly and horizontally spaced within the water storage chamber above the No. 1 liquid level sensor, and the upper ends of the two support plates are movably and horizontally equipped with filters that can be extracted from the water storage chamber.

[0015] According to the above technical solution, the beneficial effects of the chamfering device for powder metallurgy automotive parts provided by this utility model in use are as follows: (1) Before use, fix the automotive part gear horizontally on the upper end of the rotary table, and adjust the distance and height of the two movable seats according to the size of the automotive part gear so that the two grinding wheels on the two movable seats are respectively facing the grinding areas at the upper and lower ends of the gear. When in use, the rotating rotary table drives the gear fixed on its upper end to rotate slowly, and the two grinding wheels are started so that the grinding wheels at the ends of the two wheels rotate at high speed, thereby performing chamfering operation on the upper and lower ends of the gear, improving the chamfering efficiency of the gear.

[0016] (2) Before chamfering the gears, start the No. 1 water pump to transport part of the room temperature water stored in the water storage chamber to the cooling box (since the water is at room temperature in the early stage, the cooling box does not need to turn on the cooling function). The No. 2 water pump then transports the water to the nozzle, and the nozzle sprays water onto the grinding wheels of the two grinding machines, thereby cooling the grinding wheels of the grinding machines to extend their service life. This allows the waste chips removed by the two grinding machines during gear grinding to be flushed into the water storage chamber along with the sprayed water. When the water temperature in the water storage chamber rises to the threshold, the cooling function of the cooling box is activated to cool the water entering the cooling box. The cooled water then enters the nozzle through the No. 2 water pump and is sprayed onto the grinding wheels of the grinding machines again, thereby realizing water circulation and saving water resources.

[0017] In summary, this invention can simultaneously chamfer both ends of automotive parts of different sizes, improving its working efficiency. Furthermore, during the chamfering process, it can cool down the grinding wheel of the grinding machine and the gears of the automotive parts, thereby extending the service life of the grinding wheel and preventing any impact on the quality of the automotive parts gears.

[0021] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0022] like Figure 1-4 As shown, the present invention provides a chamfering device for powder metallurgy automotive parts. The device includes: a cabinet 1, a rotating platform 2 horizontally and rotatably arranged in the cabinet 1, two movable seats 4 respectively movably arranged on both sides of the rotating platform 2 and adjustable in both height and spacing, two grinding wheels 3 respectively arranged on the ends of the two rotating platforms 2 for chamfering automotive parts, and a cooling mechanism. The cooling mechanism includes: a nozzle 5, a cooling box 6, a first water pump 7, and a second water pump 9; wherein... Each of the movable seats 4 located above the grinding wheel 3 is provided with at least one nozzle 5 tilted downward toward the rotary table 2. The bottom of the cabinet 1 is integrally formed with a water storage chamber communicating with its interior. The cooling box 6, which is capable of cooling inside, is horizontally arranged on one side of the water storage chamber. A first water pump 7 with its water outlet connected to the cooling box 6 is fixedly installed in the water storage chamber. A second water pump 9 is fixed on the outer wall of the water storage chamber. The water inlet of the second water pump 9 is connected to the interior of the cooling box 6 through a circulation pipe 10, and its water outlet is connected to the two nozzles 5 respectively through water pipes.

[0023] In the above scheme, a temperature sensor for monitoring water temperature is also installed in the water storage chamber.

[0024] Before use, the automotive part gear is horizontally fixed on the upper end of the rotary table 2. The distance and height of the two movable seats 4 are adjusted according to the size of the automotive part gear so that the two grinding wheels 3 on the two movable seats 4 are respectively facing the grinding areas at the upper and lower ends of the gear. During use, the rotating rotary table 2 drives the gear fixed on its upper end to rotate slowly, and the two grinding wheels 3 are started so that the grinding wheels at both ends rotate at high speed, thereby performing chamfering operation on the upper and lower ends of the gear and improving the chamfering efficiency of the gear.

[0025] Before chamfering the gears, water pump 7 is activated to partially transfer room-temperature water stored in the water storage chamber to the cooling box 6 (since the water is initially at room temperature, the cooling box 6 does not need to activate its cooling function). Water is then pumped to nozzle 5 via water pump 9, and sprayed onto the grinding wheels of the two grinding machines 4. This cools the grinding wheels of the grinding machines 4, extending their service life. The waste material removed during gear grinding by the two grinding machines 3 is flushed into the water storage chamber along with the sprayed water. When the water temperature in the storage chamber reaches a threshold, the cooling function of the cooling box 6 is activated to cool the water entering the cooling box 6. The cooled water is then pumped back onto the nozzle 5 via water pump 9 and sprayed onto the grinding wheels of the grinding machines 4 again, thus achieving water circulation and saving water resources.

[0026] In summary, this invention can simultaneously chamfer both ends of automotive parts of different sizes, improving its working efficiency. Furthermore, during the chamfering process, it can cool down the grinding wheel of the grinding machine and the gears of the automotive parts, thereby extending the service life of the grinding wheel and preventing any impact on the quality of the automotive parts gears.

[0027] In addition, the No. 1 water pump 7 can be installed on the outer wall of the water storage chamber, with its inlet extending from the top of the water storage chamber below the water surface and leaving a certain distance from the bottom of the water storage chamber, so that the waste debris falling into the water storage chamber sinks to the bottom of the water storage chamber, thus preventing the No. 1 water pump 7 from pumping the waste debris along with the water during the process of pumping water into the refrigeration box 6.

[0028] The rotary table 2 uses technology known in the field and is existing technology without any improvements. Furthermore, the rotary table 2 is driven to rotate by a geared motor, which is waterproof.

[0029] In a preferred embodiment of this utility model, the cooling mechanism further includes: a semiconductor cooler 8; wherein, The side wall of the refrigeration box 6 is equipped with a plurality of semiconductor coolers 8, and the cooling surface of each semiconductor cooler 8 abuts against the side wall of the refrigeration box 6 or is located inside the refrigeration box 6.

[0030] In the above scheme, one of the installation methods for the semiconductor cooler 8 is as follows: 1. Ensure the surfaces of the cooling fins, radiator, and mounting base are free of impurities, burrs, and dust. After cleaning, check that the contact surfaces are completely in contact. 2. Apply thermally conductive material: Apply a thin layer of thermally conductive silicone grease to the side wall or base of the cooling unit 6, between the hot end of the cooling chip and the heat sink, and between the cold end of the cooling chip and the heat sink, to improve heat transfer efficiency. 3. Adhesion and Fixing: Place the cooling element on the side wall or base of the cooling box, adjust its position, press it in place, and fix it with screws. After covering the heat sink, press it in place as well, and squeeze out any excess thermal paste.

[0031] Installation Notes: 1. Avoid applying excessive force, which could damage the cooling element; 2. Ensure the screws are evenly stressed to prevent poor contact or deformation; 3. After installation, power on and test to check if the fan is running and if the current and voltage are normal.

[0032] The semiconductor cooler 8 is a well-known existing technology. The technology of using a semiconductor cooler to cool the interior of the refrigerator is already mature and can be applied to vehicle refrigerators. Therefore, its specific structure and operating principle will not be described again.

[0033] In addition, a lithium bromide refrigerator is used instead of a semiconductor refrigerator and a cooling box to cool the water, thereby producing water at a temperature above 0°C. In use, the inlet of the lithium bromide refrigerator can be connected to the first water pump 7, and its outlet can be connected to the second water pump 9 to achieve the water cooling process.

[0034] Under vacuum conditions, a lithium bromide absorption chiller uses water as the refrigerant and an aqueous lithium bromide solution as the absorbent to produce water at temperatures above 0°C. Lithium bromide chillers are existing technology; therefore, their specific structure and operating principles will not be elaborated upon here.

[0035] In a preferred embodiment of this utility model, the inlet end of the second water pump 9 is also connected to and fixedly provided with a water supply pipe 11, and the circulation pipe 10 and the water supply pipe 11 are respectively fixedly provided with switch valves.

[0036] In the above scheme, the outlet end of the No. 1 water pump 7 can also be equipped with a switch valve.

[0037] In use, when the water temperature in the cooling chamber 6 has not reached the threshold, the switch valve on the water supply pipe 11 can be opened, while the switch valve on the circulation pipe 10 can be closed. The inlet end of the water supply pipe 11 can be connected to a faucet, the faucet opened, and the second water pump 9 started. Water is then delivered through the faucet to the nozzle 5 to spray water and cool the grinding wheel of the grinding machine 3. When the water temperature in the cooling chamber 6 reaches the threshold, the switch valve on the water supply pipe 11 can be closed, the switch valve on the circulation pipe 10 opened, and the second water pump 9 started to deliver water from the cooling chamber 6 to the nozzle 5 to spray water and cool the grinding wheel of the grinding machine 3.

[0038] In a preferred embodiment of this utility model, the device further includes a multi-dimensional adjustment mechanism capable of adjusting both the height of the two movable seats 4 and the distance between them. The multi-dimensional adjustment mechanism includes a linear module 12 and a worm gear screw jack 13; wherein... Linear modules 12 are horizontally fixedly installed at the bottom of the cabinet 1 located on both sides of the rotating platform 2. Each linear module 12 has a fixed seat 14 fixedly installed on its slider. Each fixed seat 14 has a worm gear screw jack 13 vertically fixedly installed on its nut. Each worm gear screw jack 13 has a movable seat 4 horizontally fixedly installed on its nut.

[0039] In the above solution, the linear module, also known as a linear actuator, Cartesian robot, or linear slide, is an automated motion unit composed of linear guides, ball screws, and other components. Originating in Germany, this component achieves precise linear motion through belt or screw transmission, featuring high positioning accuracy, fast movement speed, and lightweight structure. It supports unit combinations to achieve linear and curvilinear motion of loads, making light-load automated operation more flexible and precise. In this invention, the linear module 12 is enclosed to provide dust and water protection.

[0040] The worm gear screw jack, also known as the QWL screw jack, employs a worm gear and screw combination transmission structure. It comes in two types: screw-driven up-and-down movement and nut-driven up-and-down movement. It features a self-locking function, compact structure, small size, light weight, wide range of power sources, and noiseless operation. It supports electric motor drive or manual operation, is easy to install, and can be used individually or in combination for precise height control. The lifting stroke is customizable, with a rated load of up to 150kg. It is suitable for ambient temperatures from -20℃ to +80℃ and has a long service life. The screw can be driven manually or electrically to rotate, thereby raising and lowering the nut on its shaft, which in turn raises and lowers the movable seat 4 to adjust its height.

[0041] The self-locking lifting mechanism of a worm gear screw jack mainly relies on the worm gear structure and screw transmission system to achieve its self-locking function. Of course, trapezoidal screw engagement lifting can also be self-locking and can be used as a replacement for a worm gear screw jack.

[0042] Therefore, by using the linear module 12 and the worm gear screw jack 13 in conjunction, the height and spacing of the two movable seats 4 can be adjusted. Both the linear module 12 and the worm gear screw jack 13 are existing technologies, and their operating principles and structures will not be elaborated upon here.

[0043] In addition, the linear module uses a waterproof motor, and if the worm gear screw jack is driven by a motor, it also uses a waterproof motor.

[0044] Of course, other existing regulating mechanisms can also be used to achieve the above functions. The technology is not limited to those described above.

[0045] In a preferred embodiment of the present invention, the upper end of the rotary table 2 is horizontally fixed with a clamp 15 for clamping and fixing automobile parts, the clamp 15 being a three-jaw chuck.

[0046] In the above scheme, a three-jaw chuck refers to a machine tool accessory that uses the radial movement of three evenly distributed movable jaws on the chuck body to clamp and position the workpiece. The three-jaw chuck consists of a chuck body, movable jaws, and a jaw drive mechanism. Below the guide portions of the three jaws on the three-jaw chuck, there are threads that mesh with the flat threads on the back of a disc bevel gear. When a wrench is used to rotate the small bevel gear through the square hole, the disc gear rotates, and the flat threads on its back simultaneously drive the three jaws to move closer to or retract from the center, thus clamping workpieces of different diameters. The three-jaw chuck is a known existing technology.

[0047] In a preferred embodiment of the present invention, a window communicating with the interior is provided on one side of the cabinet 1, and transparent door panels are movably provided on the side walls of the cabinet 1 on both sides of the window in the horizontal direction, which can abut against each other to block the window.

[0048] In the above scheme, before chamfering, the automotive parts gears are horizontally fixed on the rotary table 2 by the clamp 15. After adjusting the height and position of the two grinding wheels 3, before chamfering, the two door panels can be pushed close to each other and pressed together to close the window, so as to prevent the waste chips from being ground off during the chamfering process from flying out of the cabinet 1 through the window.

[0049] In a preferred embodiment of this utility model, the bottom of the cabinet 1 is uniformly provided with discharge holes communicating with its interior.

[0050] In the above scheme, during the chamfering process, the waste generated and the water sprayed by the nozzle 5 of the cooling mechanism can be discharged into the water storage chamber through the discharge hole so that the water sprayed by the cooling mechanism can be recycled.

[0051] In a preferred embodiment of this utility model, a first liquid level sensor 18 and a second liquid level sensor 19 are fixedly installed inside the water storage chamber and the refrigeration box 6, respectively.

[0052] In the above scheme, the refrigeration box 6 is also equipped with 19 and a temperature sensor to monitor the water temperature inside the refrigeration box 6. When the temperature reaches the threshold, the second water pump 9 is started to spray the cold water in the refrigeration box 6 through the circulation pipe 10 and the water pipe from the nozzle 5 to the high-speed rotating grinding wheel 3, so that the high-speed rotating grinding wheel 3 can be cooled during the chamfering process of the automotive parts gears, thus extending its service life.

[0053] In a preferred embodiment of this utility model, two support plates 17 are fixedly and horizontally spaced in the water storage chamber above the No. 1 liquid level sensor 18, and the upper ends of the two support plates 17 are horizontally and movably provided with filter elements 16 that can be drawn out from the water storage chamber.

[0054] In the above scheme, the filter element 16 consists of a frame and a filter screen horizontally fixed to the bottom of the frame for storing waste. The side wall of the water storage chamber has an outlet for the filter element 16 to be removed. Furthermore, the upper ends of the two support plates 17 each partially protrude upwards to form guide rails, while the two sides of the frame of the filter element 16 are partially recessed inwards to form guide grooves that slidably connect with the two guide rails.

[0055] In use, the filter element 16 filters out the debris falling from the cabinet 1, while the water sprayed by the cooling mechanism flows through the filter element into the water storage chamber, thus separating the water from the debris.

[0056] When it is necessary to clean the waste inside the filter element 16, the filter element 16 can be pulled out horizontally from the outlet to clean the waste stored inside the filter element 16.

[0057] In summary, the chamfering device for powder metallurgy automotive parts provided by this utility model overcomes the problem that in the prior art, during the chamfering process, the grinding wheel of the chamfering machine generates a lot of heat when it rubs against the workpiece at high speed. If the heat is not dissipated in time, it may cause the workpiece to burn or deform, or even affect the internal structure of the material, reducing the quality of the workpiece and also reducing the service life of the grinding wheel.

[0058] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0059] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0060] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
