Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding and polishing technology, and in particular to a device for removing burrs from tubular areas. Background Technology
[0002] A turbocharger is a product matched with an engine to improve engine fuel efficiency and reduce vehicle emissions. The compressor housing is one of the key components of a turbocharger. After the compressor housing is cast, the nozzle needs to be precision machined. Typically, a machined surface is formed near the edge of the nozzle, while the area around the original edge remains a rough surface. At this point, burrs and sharp edges, among other irregular surface structures, are usually formed at the junction of the machined surface and the rough surface, and these need to be removed.
[0003] In existing technologies, tools such as files and air grinders are usually used directly for removal. However, since this area is a circumferential surface and close to the edge of the pipe opening, uneven grinding and scratches on parts are likely to occur, resulting in product defects. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a burr removal device for tubular areas, aiming to improve the deburring effect at the pipe opening edge and ensure product yield.
[0005] The technical solution adopted in this utility model is as follows: A burr removal device for tubular areas includes a base and a slider. The base is provided with a sleeve, a guide, and a first fixed connection. The sleeve is used to coaxially engage with the workpiece to be polished, so that the base can rotate circumferentially relative to the workpiece to be polished. The guide is used to slide with the slider. The slider is provided with a second fixed connection part, and a locking member is provided between the second fixed connection part and the first fixed connection part. The locking member is locked to the first fixed connection part and is clearance-fitted with the second fixed connection part. A spring is sleeved on the locking member, and the two ends of the spring abut against the base and the slider respectively. The slider is equipped with a file.
[0006] The further technical solution is as follows: The sleeve portion is a circular groove.
[0007] The guide portion consists of a set of symmetrically arranged keyways, and the slider has guide keys on both sides that cooperate with the keyways.
[0008] The base is provided with a receiving area to accommodate the slider, the first fixed connection part is a threaded hole located at the bottom of the receiving area, and the locking element is a screw.
[0009] The second fixed connection part is a through hole corresponding to the threaded hole, which is located at the bottom of the slider.
[0010] The slider has an extension, and the file is disposed on the bottom surface of the extension.
[0011] The part to be polished is the opening of a press shell. The area to be polished is formed at the junction of the machined surface and the blank surface on the outer circumference of the part. The base is placed on the opening. The file is set opposite to the area to be polished along the sliding block moving direction.
[0012] The spring provides a preload force so that the file on the slider is positioned above the area to be polished.
[0013] The file is welded to the slider.
[0014] The slider has a hollow area for accommodating part of the locking component, and the second fixed connection part is located below the hollow area.
[0015] The beneficial effects of this utility model are as follows: This utility model has a reasonable structural design and is easy to operate. It utilizes the rotating cooperation between the base sleeve and the nozzle of the workpiece to be polished. One rotation is enough to polish the irregular burrs on the area to be polished, ensuring the uniformity of deburring and guaranteeing the product yield.
[0016] The slider of this invention slides into the base. When in use, pressing the slider causes the file on it to press against the area to be polished, and rotating the base once completes the polishing, which improves the convenience of operation and increases work efficiency.
[0017] In this invention, the spring acts as a buffer and limiter during the polishing process, which can prevent scratches on the parts.
[0018] Other features and advantages of this invention will be set forth in the following description or may be learned by practicing this invention. Attached Figure Description

[0027] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0028] See Figures 1 to 3 The tubular area burr removal device of this embodiment includes a base 3 and a slider 1. The base 3 is provided with a sleeve part 31, a guide part and a first fixed connection part. The sleeve part is used to be coaxially sleeved with the workpiece 4 to be polished, so that the base 3 can rotate circumferentially relative to the workpiece 4 to be polished. The guide part is used to slide with the slider 1. The slider 1 is provided with a second fixed connection part, and a locking member 5 is provided between the slider 1 and the first fixed connection part. The locking member 5 is locked to the first fixed connection part and is clearance-fitted with the second fixed connection part, thereby connecting the base 3 and the slider 1 and allowing the slider 1 to slide relative to the base 3. A spring 6 is sleeved on the locking member 5, and the two ends of the spring 6 abut against the base 3 and the slider 1 respectively to provide preload force. A file 2 is provided on slider 1.
[0029] As a preferred embodiment, the socket 31 is a circular groove provided on one side of the base 3. The base 3 is also preferably circular.
[0030] like Figure 4 and Figure 5 As shown, in a preferred embodiment, the guide portion is a set of keyways 32 arranged symmetrically, and the slider 1 has guide keys 11 on both sides that cooperate with the keyways 32.
[0031] Specifically, the base 3 is provided with a receiving area 34 for accommodating the slider 1. The first fixed connection part is specifically a threaded hole 33, and preferably two are provided, which are located at the bottom of the receiving area 34. The locking member 5 is preferably two M6 screws.
[0032] Specifically, the second fixed connection part is a through hole 12 corresponding to the threaded hole 33, which is located at the bottom of the slider 1. Preferably, the slider 1 is provided with a hollow area 13, which is used to accommodate part of the locking member 5, and the through hole 12 is specifically located below the hollow area 13.
[0033] As a preferred method, such as Figure 2 As shown, the slider 1 has an extension 101, and the file 2 is disposed on the bottom surface of the extension 101. The extension 101 is preferably bent and extends downward from the lower side of the slider 1 body.
[0034] like Figure 6 and Figure 7 As shown in the specific embodiment, the part to be polished 4 is the opening of the pressure shell. The area to be polished 402 is formed at the junction of the machined surface 401 and the blank surface 403 on the outer circumference of the part. When the base 3 is placed on the opening, the file 2 on the slider 1 is set opposite to the area to be polished 402 along the moving direction of the slider 1.
[0035] Specifically, spring 6 provides preload to position file 2 on slider 1 above the area to be polished 402.
[0036] In this embodiment, during assembly, the slider 1 and file 2 are preferably welded together as a whole. The base 3 and slider 1 are connected to the keyway 32 via guide key 11, and then fixed together using two M6 screws, each with a spring 6 mounted on it. The M6 screws are locked to the base 3 and have a clearance fit with the slider 1, allowing the slider 1 to slide against the base 3. In use, pressing the slider 1 moves it relative to the base 3 (see [reference to other components] for the direction of movement). Figure 7 (As shown by the middle arrow), the file 2 is pressed against the area 402 to be polished. Then, the base 3 is rotated, utilizing the rotational engagement between the sleeve and the pressure shell opening. One full rotation removes the irregular burrs on the area 402 to be polished. After polishing, the pressing pressure is released, and the slider 1 returns to its initial position under the preload of the spring 6, allowing the base 3 to be removed. During the polishing process, the spring 6 acts as a buffer and limiter to prevent product damage.
