Description
Technical Field
The utility model belongs to the technical field of machining, a hand-held type burring cutter is related to.
Background
In the machining process, a long hollow tubular product is often cut into a plurality of short hollow tubular products, and burrs remaining at a cut are scraped by a burr removing tool. For deburring hollow tubular products, the hollow tubular products are generally clamped on a machine tool, and burrs of the products are removed by a deburring knife. Although the mode is high in automation level and labor-saving for operators, the operation of clamping and setting the hollow tubular product and the deburring tool on the machine tool wastes much time, even the time is obviously longer than the time required by the actual deburring process, namely the preparation working time is far longer than the effective working time, so that the efficiency is lower on the whole.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a hand-held type burring cutter in order to overcome the defect that above-mentioned prior art exists.
The purpose of the utility model can be realized through the following technical scheme:
the utility model provides a hand-held type burring cutter, this cutter is including handle and the cutter arbor that links to each other, the cutter arbor on the cover be equipped with burring mechanism and hold-down mechanism, burring mechanism establish on the cutter arbor along cutter arbor axial slip cover to with handle elastic connection, hold-down mechanism can dismantle with the cutter arbor and be connected. The handle is convenient for the operating personnel to hold the cutter.
Further, the deburring mechanism comprises a blade mounting sleeve sleeved on the cutter bar and a deburring blade arranged on the outer side of the blade mounting sleeve, and a spring is arranged between the blade mounting sleeve and the end of the handle. The blade mounting sleeve can slide along the axial direction of the cutter bar and is elastically connected with the end part of the handle through a spring. The deburring blade is used for directly contacting with the hollow tubular product to remove burrs. The blade mounting sleeve is designed to be in elastic connection with the handle, so that pressure can be generated between the deburring blade and the hollow tubular product through the elastic restoring force of the spring, and burrs on the hollow tubular product can be removed better; simultaneously because the length of spring has the variability in certain extent, and then can be applicable to the hollow tubular product of different length, the flexibility is good.
Furthermore, two deburring blades are symmetrically arranged on the outer side of the blade mounting sleeve. Two burring blades that the symmetry set up contact with hollow tubulose product simultaneously, improve job stabilization nature and burring efficiency.
Furthermore, the cutter bar is provided with a guide ridge along the axial direction of the cutter bar, and the blade mounting sleeve is provided with a guide groove matched with the guide ridge. The blade mounting sleeve slides along the axial direction of the cutter bar through the matching of the guide ridge and the guide groove, and the influence on the deburring effect caused by synchronous rotation of the blade mounting sleeve and the hollow tubular product can be avoided.
Furthermore, the compressing mechanism comprises a nut which is sleeved on the cutter bar and is in threaded connection with the cutter bar and a compressing turntable which is arranged on one side of the nut and is rotationally connected with the nut, and the compressing turntable is positioned between the deburring mechanism and the nut. The nut is in threaded connection with the cutter bar, so that the pressing mechanism can be conveniently installed on the cutter bar and can be continuously screwed to press the end part of the hollow tubular product, or the pressing mechanism can be taken down from the cutter bar after being screwed out, so that the hollow tubular product can be conveniently sleeved on the cutter bar. The pressing rotary disc not only can press the end part of the hollow tubular product, but also can synchronously rotate along with the rotation of the hollow tubular product so as to reduce the rotation resistance during deburring.
Furthermore, the cutter bar is provided with an external thread matched with the nut. The cutter arbor is connected with the nut through the external screw thread can dismantle.
Furthermore, a cutter bar yielding hole is formed in the center of the pressing rotary disc, and the inner diameter of the cutter bar yielding hole is larger than the outer diameter of the cutter bar. The center of the pressing rotary table is not contacted with the cutter bar, so that the cutter bar is prevented from generating resistance to the rotation of the pressing rotary table.
Furthermore, the side of the pressing turntable is provided with an outer annular block, the side of the nut is provided with an inner annular block, and a bearing is arranged between the outer annular block and the inner annular block. The outer ring and the inner ring of the bearing are respectively connected with the outer annular block and the inner annular block, and the relative rotation of the compression turntable and the nut is realized through the bearing.
When the utility model is in actual use, an operator grips the handle with the left hand and unscrews the hold-down mechanism from the cutter bar and then detaches the hold-down mechanism; then sleeving the hollow tubular product on a cutter bar, and enabling the front end of the hollow tubular product to be in contact with a deburring mechanism; then the pressing mechanism is arranged on the cutter bar and presses the rear end of the hollow tubular product, so that pressure is generated between the front end of the hollow tubular product and the deburring mechanism; and then the operator holds the hollow tubular product by the right hand and rotates the hollow tubular product, so that the deburring mechanism removes burrs on the hollow tubular product.
Compared with the prior art, the utility model has the characteristics of it is following:
1) by designing the handheld deburring cutter, the installation, the positioning and the deburring of the hollow tubular product on the cutter bar can be quickly realized, the preparation working time is greatly reduced, and the working efficiency is improved;
2) the blade mounting sleeve is elastically connected with the handle, so that pressure can be generated between the deburring blade and the hollow tubular product through the elastic restoring force of the spring, and burrs on the hollow tubular product can be better removed; meanwhile, the length of the spring is changeable within a certain range, so that the spring can be suitable for hollow tubular products with different lengths, and the flexibility is good;
3) the nut is in threaded connection with the cutter bar, so that the pressing mechanism can be conveniently installed on the cutter bar and can be used for pressing the end part of the hollow tubular product after being screwed tightly, or the pressing mechanism can be taken down from the cutter bar after being screwed out so as to sleeve the hollow tubular product on the cutter bar; the pressing rotary disc not only can press the end part of the hollow tubular product, but also can synchronously rotate along with the rotation of the hollow tubular product so as to reduce the rotation resistance during deburring.
