The specific embodiment
For the ease of understanding the utility model, with reference to relevant drawings the utility model is described more fully below.Provided preferred embodiment of the present utility model in the accompanying drawing.But the utility model can be realized with many different forms, be not limited to embodiment described herein.On the contrary, provide the purpose of these embodiment be make the understanding of disclosure of the present utility model comprehensively thorough more.
Need to prove that when element is called as " being fixed in " another element, can directly can there be element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be to be directly connected to another element or may to have element placed in the middle simultaneously.
Unless otherwise defined, the employed all technology of this paper are identical with the implication that belongs to those skilled in the art's common sense of the present utility model with scientific terminology.Employed term is not intended to be restriction the utility model just in order to describe the purpose of specific embodiment in specification of the present utility model herein.Term as used herein " and/or " comprise one or more relevant Listed Items arbitrarily with all combinations.
See also Fig. 1, Fig. 2 and Fig. 3, in the utility model preferred embodiment, the workbench 100 of cutting off machine comprises lathe bed 110, travelling table 120 and drive unit 130.
Travelling table 120 is similar with lathe bed 110 shapes, is roughly the rectangular plate-like structure.Travelling table 120 is provided with tooth bar 121.Travelling table 120 is located at lathe bed 110 slidably, and when being used for cutting, lathe bed 110 can be used for carrying workpiece to be cut.In the present embodiment, lathe bed 110 also comprises the guide rail 113 of being located at base 111 both sides and being parallel to each other, and travelling table 120 is provided with a plurality of slide blocks 123.Slide block 123 cooperates with guide rail 113, thereby makes travelling table 120 with respect to lathe bed 110 slidably.It is pointed out that travelling table 120 is not limited to be located at lathe bed 110 slidably by the mode that guide rail 113 cooperates with slide block 123.For example, also can pulley be set at travelling table 120 or lathe bed 110, realize travelling table 120 with respect to lathe bed 110 slidably by pulley.
See also Fig. 4, drive unit 130 is fixed on the base 111, and drive unit 130 comprises servomotor 131, reductor 133 and gear 135.Because drive unit 130 is separate types with travelling table 120, thereby makes travelling table 120 lighter weight, when sliding with respect to lathe bed 110, can alleviate vibrations.
Servomotor 131 is used for providing energy, and energising back servomotor 131 is started working.Servomotor 131 can be common motor, also can be buncher etc.Because servomotor 131 is fixed on the base 111, can be along with travelling table 120 motions when cutting.Therefore, do not need to be servomotor 131 increase cable-pulling chains and design drag chain mounting structure, thereby save cost and further simplified structure.
Gear 135 is fixedlyed connected with the output shaft of reductor 133, and output shaft driven gear 135 rotates.Gear 135 meshes with tooth bar 121, the circular motion of gear 135 can be changed into the rectilinear motion of tooth bar 121.Wherein, after servomotor 131 energisings, drive reductor 133 runnings, reductor 133 running driven gears 136 rotate, and further, gear 135 cooperates with tooth bar 121, drives travelling table 120 and slides along lathe bed 110.Because tooth bar 121 moves back and forth with travelling table 120, tooth bar 121 can not expose.Therefore, can make workbench 100 overall structures of cutting off machine compacter.In addition, gear 135 is compared with ball screw with tooth bar 121, does not have violent rolling or sliding friction, and then can avoid producing very big noise.
In the present embodiment, tooth bar 121 is wall scroll, and tooth bar 121 is near a side setting of travelling table 120.Therefore, gear 135 is amesiality with the position of engagement of tooth bar 121, thereby at gear 135 during in high-speed driving, the vibration that can alleviate tooth bar 121 and gear 135.And the form that drives of monolateral gear 135 and tooth bar 121 make the part kind of workbench 100 of cutting off machine few, install simpler.It is pointed out that in other embodiments the mode that also can adopt bilateral or polygon gear to rotate.Concrete, can change the tooth bar 121 of travelling table 120 into double or many rows by wall scroll, and the gear 135 of corresponding number is set at drive unit 130.
Please continue to consult Fig. 4, in the present embodiment, drive unit 130 also comprises mount pad 136, rebound 137 and adjusts piece 138.
In the present embodiment, the side that mount pad 136 contacts with rebound 137 forms stopper slot (figure is mark not), and rebound 137 is fastened in the stopper slot and can slides along stopper slot.Stopper slot can prevent rebound 137 swing sideward moving, thereby avoid gear 135 and tooth bar 121 dislocation.
In the present embodiment, offer on the rebound 137 along the bar hole 1372 of the direction of stopper slot.Rebound 137 was installed on the mount pad 136 by bar hole 1372 and cooperating of threaded fastener.Further, bar hole 1372 is four, and lays respectively at the drift angle place of rebound 137.Therefore, can make rebound 137 fix more firmly.When needs slided rebound 137, the securing member that unscrews, slip rebound 137 were to desired location, and the threaded together securing member gets final product.Because threaded fastener can slide in bar hole 1372, so rebound 137 can be fixed on different positions.
Adjusting piece 138 is fixed on the mount pad 136.Adjust piece 138 and be provided with adjustment screw 1382, adjustment screw 1382 pass adjust piece 138 and with rebound 137 butts.Turning adjustment screw 1382 can be to rebound 137 thrust of exerting pressure, thereby rebound 137 is slided at mount pad 136.
Compare with the workbench of traditional cutting off machine, the workbench 100 of the cutting off machine in the utility model preferred embodiment has following advantage at least:
1, the workbench 100 of the cutting off machine mode that adopts gears 135 to cooperate with tooth bar 121 realizes driving, and gear 135 and tooth bar 121 are not easy to wear with respect to the ball screw of micron order.In addition, because gear 135 cooperates with tooth bar 121, can directly the circular motion of gear 135 be converted into the rectilinear motion of tooth bar 121, it is short to drive stroke, thereby can respond fast.Therefore, the precision that adopts the workbench 100 of cutting off machine to cut is higher.
2, traditional ball screw type of drive generally need arrange parts such as accurate bearing block, bearing, shaft coupling, locking nut at the leading screw two ends.And the type of drive that gear 135 cooperates with tooth bar 121 only needs gear 135, tooth bar 121 and energy generator to get final product.So the workbench 100 needed part kinds of cutting off machine are few, it is simple to install, be convenient to maintenance.
3, do not have violent rolling or sliding friction between gear 135 and the tooth bar 121, can avoid producing very big noise.Tooth bar 121 moves back and forth with travelling table 120, and tooth bar 121 can not expose, thereby makes the overall structure of workbench 100 of cutting off machine compacter.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
