Background technology
Can know following technical scheme from Chinese patent CN2728685Y and CN201500820U etc.: the saw blades groups circular sawing machine; Saw blades groups includes a pair of suitable saw blade of rotation in opposite directions; Motor that is provided with in the engine housing and gear train assembly; The inside and outside output shaft rotation that motor drives with one heart through gear train assembly and rotation direction is opposite; The saw blades groups that drive is clamped on the inside and outside output shaft flange is carried out work, and outer output shaft flange is an integral body with outer output shaft, and outer output shaft flange is the part of outer output shaft.
The shortcoming of the scheme of the outer output shaft of overall structure is: outer output shaft complex structure; The required precision of processing dimension is higher; Outer output shaft adopts material all in one piece or forging stock truck to cut usually and forms; Simultaneously, the saw blade driver element on the flange or the bottom outlet of saw blade driver element need other operation to realize, so the outer output shaft processing cost of overall structure is higher.
Summary of the invention
The purpose of the utility model is: a kind of easily manufactured, low-cost saw blades groups circular sawing machine simple in structure is provided.
The utility model is realized through following technical scheme:
The saw blades groups circular sawing machine; Motor that is provided with in the engine housing and gear train assembly; The inside and outside output shaft rotation that motor drives with one heart through gear train assembly and rotation direction is opposite; The a pair of suitable saw blades groups of the saw blade of rotation in opposite directions that contains that drive is clamped on the inside and outside output shaft flange is carried out work, and outer output shaft flange is the mechanical attachment all-in-one-piece with outer output shaft.
The advantage of the utility model is: outer output shaft flange is the branch body structure with outer output shaft, and both are integral through mechanical attachment.Outer output shaft is a tube-like piece, can adopt the few cut of pipe material to form; The saw blade driver element on outer output shaft flange and the flange or the bottom outlet of saw blade driver element are that direct moulding processes.Outer output shaft flange and outer output shaft all have the processing technology of comparative maturity, and efficient is high, the ratio of precision of processing dimension is easier to guarantee that product cost is low.
This saw blades groups circular sawing machine can be realized through the measure of describing in the following technical scheme and further improvement and perfect:
Outer output shaft flange is that interference fit connects or key connecting or thread connection with mechanical attachment between the outer output shaft.Through interference fit connection or key connecting or thread connection outer output shaft flange and outer output shaft are connected into one.
Exist adhesive attachment or pin to connect between outer output shaft flange and the outer output shaft.It can be the main connecting mode between outer output shaft flange and the outer output shaft that adhesive attachment or pin connect; Also can be useful the replenishing of interference fit connection or mechanical attachment modes such as key connecting or thread connection, improve the reliability that outer output shaft flange connects with outer output shaft.
The gear that drives outer output shaft in the transmission system is fastened on the outside of outer output shaft.Can reduce the height of the gear that drives outer output shaft, thereby reduce the cost of the gear of outer output shaft.
Saw blades groups can by two saw blades and at least a slice distance piece constitute, saw blades groups also can have at interval that two saw blades of facility constitute by linking on the blade bodies of at least one saw blade.
Outer output shaft flange is a metallic sintered products, and the saw blade driver element on the flange or the bottom outlet of saw blade driver element are that direct moulding processes.
Description of drawings
Fig. 1 is the partial sectional view that the utility model saw blades groups circular sawing machine is optimized.Output shaft flange and interior output shaft among the figure, both illustrate with one; Transmission system illustrates with bevel gear tooth system; Saw blades groups with two saw blades and at least a slice distance piece illustrate.
The specific embodiment
Saw blades groups circular sawing machine (1) among Fig. 1; Motor that is provided with in the engine housing (2) and gear train assembly (5), motor is through the axis r rotation of the inside and outside output shaft (10,20) that gear train assembly (5) drives with one heart and rotation direction is opposite; Drive is clamped in inside and outside output shaft flange (11; 21) a pair of suitable saw blades groups (30) of the saw blade (31,36) of rotation in opposite directions that contains on is carried out work, and outer output shaft flange (21) and outer output shaft (20) are through mechanical attachment (22) all-in-one-piece.The transmission system (5) of circular sawing machine (1) illustrates with bevel gear tooth system, realizes deceleration transmission through bevel gear tooth system.The gear (50) that drives outer output shaft in the transmission system (5) is fastened on the outside of outer output shaft (20), can reduce the height of the gear (50) that drives outer output shaft, thereby reduces the cost of the gear of outer output shaft.
Outer output shaft flange (21) can be that interference fit connects or key connecting or thread connection with the mechanical attachment (22) of outer output shaft (20).Through interference fit connection or key connecting or thread connection outer output shaft flange and outer output shaft are connected into one.
Outer output shaft flange (21) also can be that adhesive attachment or pin connect with the mechanical attachment (22) of outer output shaft (20).Also can be useful the replenishing of interference fit connection or mechanical attachment modes such as key connecting or thread connection, improve the reliability that outer output shaft flange connects with outer output shaft.
Interior output shaft flange (11) and interior output shaft (10) among Fig. 1 are whole.It can certainly be split.The interior output shaft flange and the interior output shaft that divide body structure, the difference in height of being convenient to regulate inside and outside output shaft flange; Output shaft flange and interior output shaft in integrally-built help improving the smoothness of saw blade.
The saw blades groups of the signal among Fig. 1 (30) is by first saw blade (31) and second saw blade (36) and a slice distance piece (38) formation.Certainly saw blades groups (30) also can be made up of two saw blades.Two saw blades can be a pair of common saw blades, also can be that at interval facility is linked to a pair of saw blade on the blade bodies of at least one saw blade.
In addition, the outer output shaft (20) that Fig. 1 comparatively clearly illustrates the saw blades groups circular sawing machine can adopt the few cut of tubular blank to form in a tubular form; Outer output shaft flange (21) complex structure, the required precision of processing dimension is higher, but the short transverse size is not very high, the suitable direct moulding of powder metallurgy that uses of outer output shaft flange (21) processes.Simultaneously the saw blade driver element (25) on the flange also directly moulding process; Certainly; The saw blade driver element also can be a pin, is independent component, but the bottom outlet of pin saw blade driver element (pin) is that direct moulding processes; Can reduce the back manufacturing procedure like this, improve the driver element positioning accuracy.Saw blade (31) is gone up setting and is accepted driver element (35) accordingly with the saw blade driver element (25) on the outer output shaft flange (21), and the rotation of accepting the saw blade driver element (25) on the outer output shaft flange (21) drives.
In the practical application, can also advance one one optimization to circular sawing machine through structure rationally is set.
