Description

Technical Field

[0001] This utility model relates to the field of chamfering, and in particular to a belt abrasive chamfering device. Background Technology

[0002] In manufacturing, chamfering is crucial. It prevents sharp edges from causing injury, facilitates assembly, and improves aesthetics. Belt grinding is often used for chamfering due to its high efficiency and flexibility. The abrasive belt moves relative to the product edge, using abrasive grains to create the chamfer.

[0003] However, belt grinding is prone to problems, often deforming due to various factors. These include uneven tension during installation, obstacles or uneven surfaces near the grinding area, and poor precision in fitting with equipment components. Once the belt deforms, its contact with the product edge becomes unstable, resulting in uneven grinding force distribution and an inability to grind chamfers stably as preset.

[0004] This makes it difficult to consistently control the chamfer angle, resulting in significant angle deviations within the same batch of products. In mechanical assembly, this can lead to poor component assembly and affect structural stability; in high-precision fields, it may cause product scrapping, resulting in substantial economic losses. Utility Model Content

[0005] In order to improve the stability of chamfering and corner processing of products and to ensure that the processed products are standardized, this utility model provides a belt abrasive chamfering device.

[0006] This utility model provides a technical solution that adopts the following approach:

[0007] A belt abrasive chamfering device includes a support base with a support section;

[0008] Abrasive belt, slidably mounted on a support base, is used for grinding chamfers;

[0009] The limiting member includes two clamping parts, which are disposed on the support base and located on the abrasive surface of the sanding belt; an clearance groove is provided between the two clamping parts, the clearance groove penetrates the limiting member, and at least one of the clamping parts is provided with a guide surface on the side near the other clamping part, the guide surface is an inclined surface pointing towards the bottom wall of the clearance groove, and the guide surface communicates with the clearance groove.

[0010] The clamping part presses against the abrasive side of the sanding belt, causing the sanding belt to adhere to the bottom wall of the clamping part.

[0011] The product requiring chamfering is clamped onto the limiting part, ensuring the bottom wall of the product fits against the bevel. The product is moved until the edge to be chamfered extends into the clearance groove and abuts against the abrasive belt. Simultaneously, the product is in contact with another clamping part, thus limiting the grinding depth. The abrasive belt is then slid, causing friction between the belt and the product edge to grind the chamfer. Due to the pressure from the clamping part, the abrasive belt deforms, conforming to the bottom wall of the clamping part and covering the clearance groove. The repeated grinding of the product edge protruding from the clearance groove as the belt slides improves the stability of the abrasive belt during grinding, enhancing the chamfering stability and resulting in a more uniform product finish.

[0012] Preferably, the support base includes a transmission assembly for driving the sanding belt, the transmission assembly including a driving wheel and a driven wheel, the sanding belt being annular and sleeved around the driving wheel and the driven wheel.

[0013] The transmission unit drives the sanding belt to move, enabling the sanding belt to slide relative to the clamping part. The driving wheel and driven wheel can also straighten the sanding belt while driving it, avoiding the need to clamp the end of the sanding belt, which can easily damage the sanding belt. This helps to improve the motion stability when the sanding belt is grinding products.

[0014] Preferably, the support base further includes a support block for supporting the sanding belt, the support block being disposed between the driving wheel and the driven wheel.

[0015] When the product's edges and corners are large enough to push the abrasive belt away, the support block supports the abrasive belt, reducing the deformation of the abrasive belt and preventing excessive pulling force on its ends. This helps protect the abrasive belt and improves grinding efficiency.

[0016] Preferably, the support base further includes a base, and the driving wheel, driven wheel and support block are all disposed on the base, and the clamping part is detachably connected to the base.

[0017] When the angle between the bottom wall and the side wall of the product to be processed is different, the corresponding clamping part is replaced to ensure that at least one side of the product can be kept on the guide surface of the clamping part during grinding, which helps to improve the overall adaptability of the device.

[0018] Preferably, the base is connected to a slide rail with openings at both ends, and the side walls of the clamping part are provided with sliders. The sliders are slidably disposed within the slide rail, and the slide rail is provided with fixing members for fixing the sliders.

[0019] When assembling or disassembling the clamping part, simply slide the clamping part into or out of the openings at both ends of the slide rail. Once the width of the clearance groove formed between the two clamping parts is suitable for the product to be ground, secure the clamping part with the fasteners to complete the installation. The constraints of the slide rail and slider ensure that the two clamping parts remain in a straight line, facilitating installation.

[0020] Preferably, the support base is provided with a drive wheel and a transmission wheel, the drive wheel and the transmission wheel are driven by a belt, the drive wheel is connected to a drive motor, the support base has a certain height, and the drive motor is located below the support.

[0021] Preferably, each of the two clamping parts has a guide surface on the side that is close to each other.

[0022] Preferably, the slide rail is provided with multiple insertion holes, the slider is provided with a threaded hole, and the slider is fixed by a screw that passes through the insertion holes and is threadedly connected to the threaded hole.

[0023] In summary, this utility model has the following beneficial technical effects:

[0024] The product requiring chamfering is clamped onto the limiting part, ensuring the bottom wall of the product fits against the bevel. The product is moved until the edge to be chamfered extends into the clearance groove and abuts against the abrasive belt. Simultaneously, the product is in contact with another clamping part, thus limiting the grinding depth. The abrasive belt is then slid, causing friction between the belt and the product edge to grind the chamfer. Due to the pressure from the clamping part, the abrasive belt deforms, conforming to the bottom wall of the clamping part and covering the clearance groove. The repeated grinding of the product edge protruding from the clearance groove as the belt slides improves the stability of the abrasive belt during grinding, enhancing the chamfering stability and resulting in a more uniform product finish.
