Description
Technical Field
[0001] The utility model relates to the technical field of chamfering machines, in particular to a chamfering machine with an adjustable cutter head. Background Art
[0002] Chamfering machine is a small precision machine tool specially used for chamfering and removing burrs of products processed by milling and planing in mold manufacturing, hardware machinery, machine tool manufacturing, hydraulic parts, valve manufacturing, textile machinery. The use of fast machine chamfering is the development trend of the machinery industry. It overcomes the processing shortcomings of existing machinery and electric tools, has the advantages of convenience, speed and accuracy, and is the best choice for chamfering of metal objects. According to the chamfering requirements, it can be divided into straight chamfering and curved chamfering.
[0003] At present, the existing chamfering machine usually includes a main body, a driving device and a cutter, and its working principle is: the driving device drives the cutter to rotate at high speed, so that the workpiece contacts the high-speed rotating cutter, thereby removing the edge of the workpiece to make it a chamfered shape.
[0004] In the above scheme, the position of the cutter in the existing chamfering machine is usually fixed, and it can only cut chamfers of fixed specifications on the workpiece. When chamfers of different specifications need to be cut, cutters of different specifications need to be replaced. When the cutting part of the cutter is worn and needs to be replaced, the entire cutter usually needs to be replaced, which is costly. Utility Model Content

The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0034] The following references Figures 1 to 4 The utility model is described.
[0035] A chamfering machine with an adjustable tool head comprises a chassis 1. An adjusting mechanism is provided at the upper end of the chassis 1. The adjusting mechanism comprises a connecting component, a guiding component and an adjusting component. A disc worktable 2 is provided on the adjusting component. A motor 3 is fixed in the chassis 1. A detachable tool is installed on the output end of the motor 3. The tool passes through the adjusting mechanism and the disc worktable 2.
[0036] When it is necessary to cut a chamfer of the required specifications on the workpiece 4, the height of the disc worktable 2 is adjusted by the adjustment mechanism, and the contact position between the top of the tool and the workpiece 4 can be adjusted, so that chamfers of different specifications can be cut. The motor 3 is started to drive the tool to rotate at high speed, and the workpiece 4 is placed on the upper end of the disc worktable 2 so that the edge of the workpiece 4 contacts the tool, so that the edge of the workpiece 4 can be cut into a chamfer. At the same time, the tool is detachable, and when the cutting part of the tool is worn, the cutting part of the tool can be replaced.
[0037] By providing an adjustment mechanism, chamfers of different specifications can be cut on the workpiece 4. At the same time, by providing a detachable tool, the worn parts of the tool can be replaced, which solves the problem that the prior art can only cut chamfers of fixed specifications on the workpiece 4 and requires replacement of the entire tool, thereby reducing production costs.
[0038] The connecting assembly comprises an annular connecting member 5 fixed to the upper end of the chassis 1 , an annular block 6 is rotatably connected inside the annular connecting member 5 , and a guide assembly is arranged at the bottom end of the annular connecting member 5 .
[0039] The annular block 6 is rotatably connected in the annular connecting member 5 .
[0040] The guide assembly includes two guide rods 7 symmetrically fixed at the bottom end of the annular connector 5 . A threaded column 8 is fixed at the lower end of the disc worktable 2 . A guide groove 801 cooperating with the guide rod 7 is formed at the lower end of the threaded column 8 .
[0041] The guide rod 7 is inserted into the guide groove 801, so that the disc worktable 2 can move up and down but cannot rotate.
[0042] The adjustment assembly includes an internal thread 601 formed on the inner wall of the annular block 6 , and the annular block 6 is threadedly connected to the threaded column 8 .
[0043] When the height of the disc workbench 2 needs to be adjusted, the annular block 6 is rotated, and at the same time, under the action of the guide rod 7, the threaded column 8 is driven to rise or fall. The rising or falling of the threaded column 8 can drive the disc workbench 2 to rise or fall, thereby adjusting the height of the disc workbench 2.

[0053] When it is necessary to cut a chamfer of the required specifications on the workpiece 4, rotate the annular block 6, and at the same time, under the action of the guide rod 7, drive the threaded column 8 to rise or fall. The rise or fall of the threaded column 8 can drive the disc worktable 2 to rise or fall, and the contact position between the cutter head 10 and the workpiece 4 can be adjusted, so that chamfers of different specifications can be cut. Start the motor 3 to drive the blade 9 and the cutter head 10 to rotate at high speed, and place the workpiece 4 on the upper end of the disc worktable 2 so that the edge of the workpiece 4 contacts the cutter head 10, so that the edge of the workpiece 4 can be cut into a chamfer. At the same time, the blade body 9 and the cutter head 10 are detachable. When the cutter head 10 is worn, it can be replaced with a new cutter head 10, without replacing the entire tool.
