Abstract
The utility model relates to edge grinding machine tools for the front angle and the rear angle of an alloy saw blade, in particular to a connecting structure for a saw blade and a saw blade support shaft, which comprises a saw blade with a central hole, and a saw blade support shaft mounted on a saw blade moving device. The saw blade is sleeved on the saw blade support shaft through the central hole, and a hydraulic expansion sleeve is mounted between the saw blade and the saw blade support shaft. The central hole of the saw blade and the support shaft are concentrically and integrally connected through the hydraulic expansion sleeve in even expansion, and thereby fit clearance between the saw blade and the saw blade support shaft is eliminated, and edge grinding state of the saw blade reaches a use state as far as possible. Therefore, edge grinding precision of the front angle and the rear angle of the saw blade is improved greatly, utilization effect of the saw blade can be improved, and the connecting structure is quite applicable to edge grinding tools for the front angles and the rear angles of high-grade hard alloy saw blades.
Description
Technical field
The utility model relates to angle, alloy saw blade front and back cutter grinding machine, the syndeton of specifically a kind of saw blade and saw blade back shaft.
Background technology
In order to guarantee to obtain good sawing quality, the carbide alloy sawtooth not only will be processed into various flute profile, and its cutting edge precision more will reach very high level.In general, at different size, the hard saw blade of different purposes, usually to adopt vertical angle, saw blade front and back cutter grinding machine, exactly the saw blade vertical hanging is installed on the saw blade back shaft of lathe, connects, center by common core retainer plate, tapered core cover between the endoporus of saw blade and the back shaft.Skive is installed on the bistrique vertical shaft of multi-axis numerical control, grind the flute profile key elements such as anterior angle, relief angle, cutting edge inclination of each sawtooth by land, bistrique adopts the high-precision servo motor-driven, but both stepless time adjustments, it is also very steady to turn round, and can satisfy the high accuracy sharpening of sawtooth, the feeding of roll flute, withdrawing move along the high accuracy guideway, no gap error, feed accuracy, good reproducibility can guarantee that the various piece of sawtooth has the uniformity of height.
But owing to have certain fit clearance between the saw blade back shaft of saw blade centre bore and lathe, during the saw blade sharpening, there is bigger error in both centres of gyration, even the sharpening precision is high again, saw blade still tangible deviation can occur when practical application, thereby may have influence on the result of use of saw blade.
Summary of the invention
It is poor that the utility model is intended to solve the saw blade back shaft and the saw blade centre bore quality of fit of traditional cutter grinding machine, the problem that saw blade sharpening precision is lower, and a kind of centering precision when improving the saw blade sharpening is provided, improve the saw blade of saw blade precision level and the syndeton of saw blade back shaft.
The technical scheme that the described problem that solves the utility model adopts is: the syndeton of a kind of saw blade and saw blade back shaft, comprise the saw blade that has centre bore, be installed in the saw blade back shaft on the saw blade mobile device, described saw blade is contained on the described saw blade back shaft by its center borehole jack, and hydraulic expanding cover is housed between the two.
Compared with prior art, the utility model expands uniformly by hydraulic expanding cover and makes saw blade centre bore and back shaft keep connecting as one with one heart, eliminates the fit clearance of saw blade and saw blade back shaft, and the sharpening state that makes saw blade is as much as possible near user mode.Therefore, the utility model has improved angle, saw blade front and back sharpening precision greatly, can improve the result of use of saw blade, is highly suitable for angle, the front and back cutter grinding machine of high-grade hard alloy saw blade.
Description of drawings
Fig. 1 is a structural representation front view of the present utility model.
Fig. 2 is a structural representation vertical view of the present utility model.
Among the figure: lathe bed 1, saw blade 2, mobile device 3, saw blade back shaft 4, hydraulic expanding cover 5 divides tooth device 6, grinding head motor 7, guide rail 8, bistrique 9, emery wheel 10, fluid pressure line 11, Hydraulic Station 12, fixing device for saw blades 13.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Referring to Fig. 1, Fig. 2, angle cutter grinding machine before and after the hard alloy saw blade, mainly form by following several major parts: the one, bed piece 1 is used for installing saw blade 2 and bistrique 9 parts; The 2nd, the saw blade support section comprises saw blade back shaft 4 and mobile device 3 thereof; The 3rd, the branch tooth device 6 of saw blade 2 is used for uniform calibration sawtooth, and the sharpening benchmark is provided; The 4th, fixing device for saw blades 13 gives stable clamping when saw blade 2 sharpenings, guarantees the sharpening precision; The 5th, the saw blade grinding attachment comprises servomotor 7, guide rail 8, bistrique 9, emery wheel 10 and all places control element; The 6th, the oil cooling system of grinding head grinding wheel 10, fire-proof smoke-proof device; The 7th, digital control system and electrical apparatus control system are used for finishing every functions such as saw blade 2 rotations, bistrique 9 feedings, can realize No. 2 clampings of saw blade, can finish grind each preceding relief angles of sharpening saw blade 2 automatically by tooth; The 8th, hydraulic system, the centralized positioning of control fixing device for saw blades 13 and saw blade 2.
The utility model belongs to the centralized positioning structure of saw blade 2.As seen from Figure 1, Figure 2, described saw blade 2 is contained on the described saw blade back shaft 4 by its center borehole jack, and hydraulic expanding cover 5 is housed between the two, and this hydraulic expanding cover 5 is controlled by Hydraulic Station 12 by fluid pressure line 11.
The operation principle of angle cutter grinding machine is before and after the hard alloy saw blade: after saw blade 2 is sleeved on the saw blade back shaft 4, by hydraulic expanding cover 5 both are closely linked into an integrated entity, by mobile device 3 saw blade 2 is moved to the operating position then, fixing device for saw blades 13 clamps.Grinding head motor 7 drives bistrique 9 by dividing tooth device 6 by the tooth grinding by guide rail 8 during grinding.
