Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology for machine tools, specifically to an adjustable depth deburring tool. Background Technology

[0002] During machining, workers inevitably leave burrs inside the hole cavity when drilling. Most existing deburring tools are made of a single piece of cemented carbide. After long-term wear, the tool becomes shorter and cannot be installed properly, requiring replacement of the entire tool, which is costly. Moreover, when deburring workpieces with a small distance between the side hole and the side wall, ordinary guide sleeves or depth-fixing tools cannot be used properly. Furthermore, different tools are required to deburr holes of different depths, and frequent tool changes affect work efficiency. Existing guide sleeves are prone to damaging the surface of parts during use, affecting their usability. Therefore, there is a need for a deburring tool that can adapt to different conditions and has an adjustable depth-fixing distance. Utility Model Content

[0003] The technical problem to be solved by this utility model is that when the distance between the edge hole and the side wall of a part is small, the existing guide sleeve or depth-fixing tool cannot be properly placed, resulting in the inability to deburr at a fixed depth.

[0004] This utility model is achieved through the following technical solution: an adjustable depth deburring tool, comprising a base component, on which a tool assembly for deburring is mounted, and on which an auxiliary positioning component for displaying depth data is mounted, the tool assembly comprising a mounting part, a cutting part, and a guide part, the cutting part comprising a carbide segment fixedly mounted on the mounting part, the carbide segment having a spline groove for connecting to the guide part, the cutting part further comprising an auxiliary positioning tool assembly disposed on the carbide segment, and a chamfering cutter for chamfering and deburring holes slidably mounted on the auxiliary positioning tool assembly of the rolling bearing, the chamfering cutter being fixedly connected to the guide part.

[0005] Furthermore, both the carbide segment and the chamfering tool are made of carbide; the mounting part includes a clamping section for mounting to the base component, a steel segment is fixedly mounted on the clamping section, and the steel segment is fixedly connected to the carbide segment; the steel segment is provided with a threaded section for connecting to the guide part; the steel segment is provided with a connecting key for connecting to the carbide segment, and the steel segment and the carbide segment are welded together via the connecting key; the clamping section, the steel segment, and the connecting key are all made of 45 steel.

[0006] Furthermore, the guide portion includes an adjusting sleeve that is threadedly connected to the steel section, a connecting sleeve that is rotatably mounted on the adjusting sleeve, the connecting sleeve being splinedly connected to the carbide section, the chamfering cutter head being fixedly mounted to the connecting sleeve, a rolling bearing being fixedly mounted on the connecting sleeve, the inner side of the rolling bearing being fixedly mounted to the connecting sleeve, and a guide sleeve for guiding to a fixed depth being fixedly mounted on the outer side of the rolling bearing.

[0007] Furthermore, the adjusting sleeve, connecting sleeve, and guide sleeve are all made of aluminum alloy, which has good plasticity, making it easy to install rolling bearings and the whole assembly, and has low hardness, making it less likely to scratch the surface of the deburred workpiece.

[0008] Furthermore, the auxiliary positioning component includes a comparison range fixedly installed on the guide for comparing depth data, and the auxiliary positioning component also includes a comparison ring fixedly installed on the mounting part.

[0009] Furthermore, the comparison ring is provided with a range bar, and the comparison range cooperates with the range bar on the comparison ring to display the constant depth data.

[0010] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0011] 1. This utility model, through the setting of the adjusting sleeve, can adjust the position of the guide sleeve and the chamfering cutter head, ensuring that the chamfering cutter head is always in contact with the hole opening position. In addition, when adjusting, it can be used with the auxiliary positioning component to compare and display the adjusted distance, and can adapt to deburring work of holes of different depths.

[0012] 2. The cutting part of this utility model is made of cemented carbide, which has stronger cutting performance and cutting life. The mounting part is made of 45 steel, which ensures normal clamping of the tool and saves costs. The adjusting sleeve, connecting sleeve and guide sleeve are all made of aluminum alloy, which has good plasticity and facilitates the installation of rolling bearings and the whole. It has low hardness and is not easy to scratch the surface of the deburred workpiece.

[0013] 3. The tool assembly of this utility model has a simple overall structure, and the maximum outer diameter of the mounting part and the cutting part can be effectively controlled, which can better complete the fixed-depth deburring of narrow edge holes. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are for explaining the utility model only and are not intended to limit the utility model. It should be noted that this utility model is already in the actual research and development stage. Example

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, an adjustable depth deburring tool includes a base component 1, a tool assembly 2 for deburring is mounted on the base component 1, and an auxiliary positioning component 3 for displaying depth data is mounted on the tool assembly 2. The tool assembly 2 includes a mounting part, a cutting part, and a guide part. The cutting part of the tool assembly 2 includes a carbide segment 203 fixedly mounted on the mounting part, and a spline groove 209 for connecting the guide part is provided on the carbide segment 203. The cutting part also includes the auxiliary positioning component tool assembly 2 provided on the carbide segment 203. A chamfering head 204 for chamfering and deburring holes is slidably mounted on the auxiliary positioning component tool assembly 2 of the rolling bearing 206, and the chamfering head 204 is fixedly connected to the guide part.

[0023] The basic component 1 includes a deburred workpiece 101 and a clamping head 102. The deburred workpiece 101 requires the deburred hole to be close to the side wall, so traditional guide sleeves and depth-fixing tools are limited. The clamping head 102 is a pneumatic drill-type clamp. The clamping section 201 is fixedly clamped on the clamping head 102 for use. The clamping head 102 is connected to CNC machining equipment for use.

[0024] The tool assembly 2 includes a clamping section 201 fixedly mounted on a chuck head 102. A steel section 202 is integrally connected to the clamping section 201, and a connecting key 211 is integrally connected to the steel section 202. A carbide section 203 is welded to the steel section 202 via the connecting key 211. The carbide section 203 has a spline groove 209. The clamping section 201, the steel section 202, and the connecting key 211 are all made of 45 steel. A connecting sleeve 207 is splined to the carbide section 203 via the spline groove 209. The tool tip of the carbide section 203 also has an auxiliary positioning component. The tool assembly 2 is slidably mounted with a chamfering cutter head 204 for deburring holes. Both the carbide section 203 and the chamfering cutter head 204 are made of carbide. Most existing tools are made of a single piece of carbide. After long-term wear, the tool becomes shorter and cannot be properly installed on the chuck head 102, requiring the entire tool to be replaced, which is costly. In this application, the cutting part is made entirely of carbide, which has stronger cutting performance and cutting life. The mounting part is made of 45 steel. After long-term wear, only the cutting part needs to be replaced, ensuring normal tool clamping while saving costs.

[0025] The chamfering cutter head 204 is fixedly installed with the connecting sleeve 207. A threaded section 210 is provided on the steel section 202, through which an adjusting sleeve 205 is threadedly connected. The connecting sleeve 207 and the adjusting sleeve 205 are rotatably installed. A rolling bearing 206 is fixedly installed on the connecting sleeve 207. The inner side of the rolling bearing 206 is fixedly installed with the connecting sleeve 207, and a guide sleeve 208 is fixedly installed on the outer side of the rolling bearing 206. The rolling bearing 206 allows the guide sleeve 208 and the carbide section 203 to rotate freely and independently. The adjusting sleeve 205, connecting sleeve 207, and guide sleeve 208 are all made of aluminum alloy, which has good plasticity, facilitating the installation of the rolling bearing 206 and the whole assembly, and has low hardness, making it less likely to scratch the deburred workpiece. On the surface of 01, a comparison ring 302 is fixedly installed on the adjusting sleeve 205, and a comparison range gauge 301 for comparing fixed depth data is fixedly installed on the steel section 202. The comparison range gauge 301 is provided with a range bar (the number of range bars is set according to the requirements, and one range bar is 1mm apart). The comparison ring 302 and the range bar of the comparison range gauge 301 cooperate to display the fixed depth data. The overall structure of the tool assembly 2 is simple. When it is necessary to deburr holes of different diameters, the maximum outer diameter of the steel section 202 and the carbide section 203 can be replaced according to the usage requirements (adjusted according to the size of the hole), thereby completing the fixed depth deburring of holes with narrow edges and different hole diameters.

[0026] During operation, when deburring the holes of the deburred workpiece 101, the depth of the hole is measured in advance. Based on the measured depth, the position of the guide on the mounting part is adjusted. During adjustment, the adjusting sleeve 205 is rotated, which in turn drives the connecting sleeve 207, the guide sleeve 208, and the comparison ring 302 to move up and down on the steel section 202. When the connecting sleeve 207 moves, it drives the chamfering cutter head 204 to move, so that the chamfering cutter head 204 always fits the hole opening position, so that the deburring chamfer of the hole opening is not greater than 0. The overall distance of movement is determined by the position of the moving comparison ring 302 on the comparison range gauge 301, thereby controlling the extension of the carbide section 203 tool head and completing the tool depth adjustment. For example, when deburring a hole with a depth of 10mm, the adjusting sleeve 205 is manually rotated, which moves the connecting sleeve 207, guide sleeve 208, and comparison ring 302 on the steel section 202. The operator observes the comparison ring 302 directly on the comparison range gauge 301 until it reaches a position of 10mm. When the rotation of the adjusting sleeve 205 is stopped, the axial distance between the end of the guide sleeve 208 close to the surface of the workpiece 101 and the end of the carbide section 203 that penetrates into the workpiece 101 is 10mm. At this time, the position of the chamfering cutter head 204 also moves with the movement of the guide sleeve 208. When it is necessary to increase the hole depth range, rotate the adjusting sleeve 205 clockwise. When it is necessary to decrease the hole depth range, rotate the adjusting sleeve 205 counterclockwise. After the adjustment is completed, the tool assembly 2 is installed on the clamping head 102 as a whole, and then the deburring of the hole of the deburred workpiece 101 is completed by the CNC equipment.
