Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gear processing, in particular to a gear chamfer burr cleaning device. Background Art
[0002] In the process of gear processing, gear rough processing equipment such as gear hobbing, gear shaping, and gear rolling are usually used to rough process the gears. After the gear rough processing is completed, sharp burrs will be left on the tooth side. This burr needs to be removed by a chamfering machine. After the chamfering machine scrapes off the burr, the surface of the part is left with cutting oil from the gear hobbing, which makes the scraped burr easily adhere to the tooth side. At present, there are several ways to clean the chamfer burrs to solve the above problems: (1) Put the chamfered part into a box filled with cleaning agent, clean it with a brush, and then use compressed air to blow dry the gear surface, and finally perform a secondary rust prevention treatment. (2) Use compressed air to blow directly on the tooth side during the processing to blow the burrs away from the part surface. (3) Put the chamfered part into an ultrasonic cleaning machine for ultrasonic cleaning, and use compressed air to blow dry after cleaning, and finally perform a secondary rust prevention treatment. (4) The chamfering machine is modified by adding a cleaning and drying device during the chamfering process. First, the gear surface is cleaned with a cleaning agent, then the gear surface is dried with compressed air, and finally a secondary anti-rust treatment is performed.
[0003] The existing cleaning methods have the following problems: (1) Manual cleaning with a brush is very labor-intensive, and the cleaning agent is easy to splash onto the skin during the cleaning process. If the cleaning is not dried in time after cleaning, it is easy to cause rust. After cleaning, secondary rust prevention treatment is required, which is time-consuming. (2) When compressed air is used for cleaning during the processing, on the one hand, it cannot ensure that all burrs are cleaned thoroughly, resulting in burrs remaining. On the other hand, high-pressure compressed air blown on the surface of the part will atomize the cutting oil on the surface of the part. The atomized cutting oil pollutes the surrounding environment greatly, and the operator inhaling the atomized cutting oil has a great impact on the health of the body. (3) When the parts are placed in an ultrasonic cleaning machine for cleaning, because the ultrasonic cleaning machine has no chip removal system, the burrs dropped will accumulate at the bottom of the cleaning machine, causing the cleaning machine to be blocked and the cleaning agent to deteriorate. (4) The modification process of adding a cleaning and drying device to the chamfering machine is complicated and the modification cost is high. At the same time, the modified chamfering machine needs to use a cleaning agent to clean the tooth surface during the chamfering process, and cannot use cutting oil for cutting lubrication during processing, resulting in poor chamfering quality of the parts.

[0037] See also Figure 1-Figure 5 A gear chamfer burr cleaning device provided in an embodiment of the present application includes a driving assembly and a cleaning assembly; the driving assembly includes a core shaft 11 and a pressure cover 12; one end of the core shaft 11 is provided with a positioning shaft 11-1 that matches the inner hole diameter of the gear, and the end of the positioning shaft 11-1 is provided with a positioning end face 11-2; one end face of the pressure cover 12 contacts the end face of the gear and provides a clamping force for the gear; the cleaning assembly includes a scraper wheel 21, a magnetic ring 22 and a support frame 24; the outer edge of the first end face of the scraper wheel 21 contacts the outer edge of the end face of one side of the gear, and the contact part covers the gear teeth from the tip to the root, and the second end of the scraper wheel 21 is rotatably mounted on the support frame 24; the outer circumferential surface of the scraper wheel 21 is provided with a circumferential groove 21-1; the magnetic ring 22 is fixed in the groove 21-1.
[0038] Through the above technical scheme, one end of the core shaft 11 is installed on the chamfering machine, and the processed gear is sleeved on the positioning shaft 11-1 at the other end of the core shaft 11, which plays a radial positioning role on the processed gear and prevents the gear from generating relative movement in the diameter direction; the positioning end face 11-2 at the end of the positioning shaft 11-1 contacts with one end face of the gear to realize the axial positioning of the gear; the first end face of the pressure cover 12 contacts with the other end face of the gear, and the second end of the pressure cover 12 is installed on the chamfering machine and connected to the hydraulic cylinder at the same time to provide pressure for the contact surface between the first end and the gear, thereby pressing the gear and driving the gear to rotate during the rotation process of the core shaft 11 and the pressure cover 12.
[0039] When the drive assembly drives the gear to rotate, the outer edge of the first end face of the scraper wheel 21 contacts the outer edge of the gear end face, and the scraper wheel 21 generates a rotational motion in the same direction as the linear velocity of the gear due to the friction force. During the rotation of the gear and the scraper wheel 21, the outer edge of the end face of the scraper wheel 21 cuts off the burrs from the tip to the root of the gear end face. At the same time, the burrs are sucked away from the gear by the magnetic force of the magnetic ring 22 in the groove 21-1 of the scraper wheel 21. As the processed gear and the scraper wheel 21 continue to rotate, the burrs on one side of the processed gear are continuously cut off and cleaned by the magnetic ring 22 until the processed gear rotates more than one circle, completing the cutting and cleaning of the burrs on one side of the gear. Repeat the above operation to complete the cutting and cleaning of the burrs on the other side of the gear.
[0040] The gear chamfering burr cleaning device of the present embodiment does not require the use of cleaning agents and will not affect the environment; it cleans burrs by magnetic attraction without affecting the cutting oil attached to the gear surface, and there is no need to perform secondary rust prevention treatment on the gear after cleaning; there is no need to structurally modify the existing chamfering machine, and only the scraper knife in the existing chamfering machine needs to be replaced, effectively reducing the modification cost and modification cycle; it can be installed on the chamfering machine at the same time as the chamfering knife, so that the three processes of chamfering, burr cutting and burr cleaning can be carried out simultaneously, saving labor costs and improving production efficiency.
[0041] Preferably, two cleaning components are provided, symmetrically arranged on both sides of the gear. The outer edges of the end faces of the two scraper wheels 21 contact the outer edges of the end faces of both sides of the gear, and the contact parts cover the tooth tip to the tooth root of the gear teeth. The burr cleaning work on both sides of the gear can be completed after the gear rotates one circle.
[0042] Further preferably, the scraper wheel 21 is conical, and the end contacting the outer edge of the gear end face is a large round end. The advantage of such an arrangement is that the end face of the scraper wheel 21 forms an acute angle with the outer circle, which can more effectively cut burrs.
[0043] Further preferably, the maximum outer diameter of the groove 21-1 is smaller than the maximum outer diameter of the scraper wheel 21. The maximum outer diameter of the groove 21-1 is 1 mm smaller than the maximum outer diameter of the scraper wheel. If the maximum outer diameter of the groove 21-1 is the same as the maximum outer diameter of the scraper wheel 21, the magnetic ring 22 in the groove 21-1 will contact the end face of the gear, and the magnetic ring will generate an adsorption force on the gear, affecting the rotation of the gear and affecting the entire burr cleaning work.
[0044] In some optional embodiments, the cleaning assembly further includes a copper scraper 23, which is fixed on the support frame 24, and the lower surface of the copper scraper 23 is in contact with the upper surface of the magnetic ring 22. When the burrs accumulate to a certain extent on the outer surface of the magnetic ring 22, the magnetic ring 22 needs to be cleaned. The copper scraper 23 is provided to scrape off the burrs on the magnetic ring 22, and there is no need to clean the magnetic ring 22. The working principle is as follows: Since the lower surface of the copper scraper 23 is in contact with the upper surface of the magnetic ring 22, when the magnetic ring 22 rotates to the front end of the copper scraper 23, the burrs are gradually scraped to the outer surface of the copper scraper 23 by the front end of the copper scraper 23. Since the copper plate has the function of isolating the magnetic field, the burrs lose the attraction of the magnetic ring 22 on the scraper wheel 21 and fall naturally.
[0045] Preferably, the front end of the copper scraper 23 has an angle. Further, the angle is 20°. The angle at the front end of the copper scraper 23 makes it easier for the copper scraper 23 to scrape the burrs on the surface of the magnetic ring 22 to the outer surface of the copper scraper 23. If the angle is too large, the burrs are not easily guided to the copper scraper, and if it is too small, the strength of the front end of the copper scraper 23 is too low. The 20° angle at the front end of the copper scraper 23 not only ensures the strength of the front end of the copper scraper 23, but also makes it easy to scrape the burrs onto the copper scraper 23.
[0046] Preferably, a connecting shaft 21-2 is provided at one end of the scraper wheel 21, and an inner hole 24-1 is provided in the support frame 24, and the connecting shaft 21-1 and the inner hole 24-1 are matched and connected. The connecting shaft 21-2 is installed in the inner hole 24-1 to realize the rotation connection between the scraper wheel 21 and the support frame 24.
[0047] The working process of the gear chamfering burr cleaning device described in this embodiment is as follows: Step 1, install the driving assembly. Install the first end of the mandrel 11 and the first end of the pressure cover 12 on the chamfering machine, and at the same time, connect the pressure cover 12 to the hydraulic cylinder of the chamfering machine; put the processed gear on the positioning shaft 11-1 at the second end of the mandrel, the end face of the first side of the gear contacts the positioning end face 11-2 of the mandrel 11, and the second end face of the pressure cover 12 contacts the second side end face of the gear to press the gear. Step 2, install the cleaning assembly. Install the two sets of cleaning assemblies symmetrically on both sides of the gear, so that the outer edge of the end face of the scraper wheel 21 contacts the outer edge of the end face on both sides of the gear, and adjust the contact width so that the contact part covers the gear teeth from the tip to the root. Step 3, operate the chamfering machine. The core shaft 11 and the pressure cover 12 drive the gear to rotate during the rotation process, and the scraper wheel 21 generates a rotational motion in the same direction as the linear velocity of the gear. As the processed gear and the scraper wheel 21 continue to rotate, the burrs on both sides of the processed gear are continuously cut off and attracted by the magnetic ring 22 and cleaned by the copper scraper 23 until the processed gear rotates more than one circle, completing the cutting and cleaning of the burrs on both sides of the gear.
[0048] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other. For the system or device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part description.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
