Moreover, manual polishing is greatly affected by subjective factors, and the consistency of the deburring effect of products is poor. The conventional deburring device has a single structure, and the service life and rigidity of the brush as a key deburring component are difficult to meet the application requirements. In order to prevent the brush from spreading during rotation, the brush head is usually relatively short, and the wear resistance of the brush is uneven, and the wear compensation also needs manual intervention. In order to ensure the convenience of operation, the efficiency of processing, and the stability of service life, a new deburring technology is urgently needed.

First, the gear body is moved between the two clamping discs, then the two clamping plates drive the two clamping discs to move, thereby clamping and fixing the gear body, the clamping disc drives the gear body to rotate, the lifting plate drives the gear body to move downward through the two clamping plates and the two clamping discs, the gear teeth of the gear body enter the fixed groove, and then the brush is used to polish the burrs on the gear body. The device is a deburring device independent of the machining center, the product production investment is high, and the device does not consider the wear amount of the brush. UTILITY MODEL CONTENTS

[0035] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0036] This utility model discloses a product surface burr removal device and a machining center suitable for machining centers. The deburring process is integrated into the machining center, and the brush operation is directly driven by the spindle. This not only makes the operation safe and convenient, but also effectively reduces labor intensity and safety risks. It can also ensure a high degree of consistency in deburring effect, greatly improve the stability of product quality, and eliminate the need for investment in separate deburring equipment, significantly shortening the production cycle. Furthermore, the quick-release and elastic components allow the brush head to extend out of the sleeve, thereby quickly adjusting the brush length to compensate for brush wear.

[0037] According to the burr removal device for product surfaces suitable for machining centers disclosed in this utility model, such as Figure 1 , Figure 2 As shown, the assembly includes a mounting handle 1, a sleeve 2, and a brush body 5. The mounting handle 1 is coaxially mounted on the bottom of the spindle of the machining center. The top of the sleeve 2 is provided with a clamping part, which is coaxially clamped to the bottom of the mounting handle 1. The bottom of the sleeve 2 is provided with a brush mounting cavity. The brush body 5 is coaxially and slidably mounted in the brush mounting cavity and is fixed by a quick-release component. The brush head at the bottom of the brush body 5 extends out of the brush mounting part. An elastic element is installed between the top of the brush body 5 and the bottom of the brush mounting cavity to apply a downward elastic force to the brush body 5.

[0038] Mounting handle 1 is coaxially connected to the machining center spindle. The clamping part at the top of sleeve 2 is fixed to the bottom of mounting handle 1. The brush body 5 is installed in the brush mounting cavity of sleeve 2 via a quick-release component. An elastic element (such as a preload spring 4) continuously presses the brush body 5 downward, so that the brush head and the workpiece surface maintain a constant contact pressure, thereby realizing the direct drive of the deburring process and the machining center spindle, eliminating the need for secondary clamping. The elastic element adaptively compensates for brush wear, ensuring a stable deburring effect. Furthermore, by setting part of the brush head in the brush mounting cavity, the bottom edge of the brush mounting cavity can be used as a limit to prevent the brush from spreading out during rotation and to compensate for brush wear.

[0039] The brush body 5 includes a brush head and a brush base. The brush head is installed at the bottom of the brush base. The entire brush base is installed inside the brush mounting cavity, with a portion of the brush head located inside the brush mounting cavity and the remaining portion extending out of the cavity. The brush base and brush head are designed as separate units, with the brush head portion embedded in the brush mounting cavity and mechanically restrained to prevent swaying. The modular structure facilitates quick brush head replacement, adapting to different materials or shapes of burrs, while enhancing the rigidity of the brush during operation. In a preferred embodiment, the brush head includes a silicon carbide brush head or a ceramic fiber brush head, and the mounting handle 1 includes an HSK base handle integrated onto the spindle of an external machining center.

[0040] The sleeve 2 has a vertically oriented through groove on the side wall of the brush mounting cavity. The quick-release component includes a set screw 3, and the side wall of the brush base has a threaded hole that matches the set screw 3. In the fixed state, the screw of the set screw 3 passes through the through groove and is threadedly connected to the threaded hole. The head of the set screw 3 abuts against the edge of the through groove, thereby fixing the brush base to the brush mounting cavity. In the unlocked state, the head of the set screw 3 separates from the edge of the through groove, allowing the brush base to slide within the brush mounting cavity. The through groove on the side wall of the sleeve 2 is aligned with the threaded hole of the brush base. The set screw 3 passes through the through groove and is screwed into the threaded hole. Locking is achieved by the abutting between the head of the set screw and the edge of the through groove. With the above configuration, the brush extension length can be quickly adjusted without tools to adapt to different burr heights and workpiece profiles, thus compensating for brush wear.

[0041] The elastic element includes a pre-tension spring 4, with its two ends connected to the top of the brush base and the bottom of the brush mounting cavity, respectively. In the fixed state, the pre-tension spring 4 is compressed; in the unlocked state, the brush base moves downwards under the elastic force provided by the pre-tension spring 4. The two ends of the pre-tension spring 4 abut against the top of the brush base and the top of the brush mounting cavity, respectively. In the locked state, the spring is compressed and stores energy; after unlocking, the spring releases its elastic force, pushing the brush downwards. This engages with the set screw 3 to quickly compensate for brush wear, avoid frequent brush head replacements, and improve the stability of continuous operation.

[0042] The sleeve 2 has a through-flow coolant channel on its side wall; the inlet end of the coolant channel is connected to an external cooling system, and the outlet end of the coolant channel faces the working area of ​​the brush head. By setting up the coolant channel, the brush head temperature can be reduced simultaneously, and debris can be flushed away to prevent secondary adhesion, thereby improving the surface finish.

[0043] The brush base has wear scale lines on its side wall, and a reference mark line is correspondingly set on the edge of the through groove of the brush mounting cavity. When the brush body 5 is adjusted downwards, the relative position change between the wear scale lines and the reference mark line is used to indicate the amount of wear on the brush head. Operators can intuitively judge the remaining lifespan of the brush and avoid excessive wear leading to processing failure.

[0044] The machining center provided by this utility model includes a machining center body and a product surface burr removal device suitable for machining centers. The mounting handle 1 is coaxially mounted on the bottom of the machining center spindle and can rotate with the spindle. The machining center also includes a laser detection probe, which is positioned facing the brush head and used to detect the wear of the brush head. During operation, the spindle rotates, thereby driving the brush to rotate synchronously. According to the precise trajectory set by the CNC program, the designated area is precisely cleaned according to the location where burrs need to be removed from the corresponding product. The wear value is detected by the laser detection probe after a specific number of cycles and compared with the initial value to calculate a compensation value. The compensation value is then input into the system through the CNC macro program for compensation. This method avoids the need for manual intervention after brush wear.
