Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Shown in composition graphs 1 to Fig. 6, be the utility model one preferred embodiment, a kind of plane circulation device of tooth-like belt transmission, comprise base 101, at least one carry control 103, pair of guide rails 102 and transmission device 20.Be arranged on base 101 to pair of guide rails 102 parallel interval, carry and control 103 and be slidably mounted on guide rail 102.Carry and control 103 bottom surfaces there is the first sliding tray 1031, carry and control 103 and be slidably mounted on guide rail 102 by the first sliding tray 1031.Transmission device 20 is controlled 103 for driving year and is done straight line loopy moving along quadrangle track, and it comprises main drive gear 200.As shown in Figure 3, main drive gear 200 comprises motor 203, tooth-like belt 201 and some flute profiles wheel 202.Flute profile wheel 202 is positioned at the both sides of pair of guide rails 102, and is in transmission connection with motor 203.Particularly, flute profile wheel 202 can be arranged on base 101.Tooth-like belt 201 is assemblied on flute profile wheel 202, and the tooth that the tooth of tooth-like belt 201 and flute profile take turns 202 engages each other, and can move along the length bearing of trend of guide rail 102.
Shown in composition graphs 5 and Fig. 6, transmission device 20 also comprises follower 300.Follower 300 comprises the meshing part 301 being arranged at and carrying and control bottom 103, and meshing part 301 is meshed with the tooth of tooth-like belt 201.Be with dynamic load to control 103 when tooth-like belt 201 moves and do straight-line motion.
As shown in Figure 4, plane circulation device also comprises two transfer docking mechanisms 400, two transfer docking mechanisms 400 lay respectively at the two ends of guide rail 102, and be connected between two guide rails 102, the length bearing of trend of its length bearing of trend and guide rail 102 is perpendicular, for controlling 103 and carry out linear by moving to carrying on guide rail 102 one end along perpendicular to the length bearing of trend of guide rail 102, thus will carry and control 103 and move on another guide rail 102 from a guide rail 102.
Transfer docking mechanism 400 comprises slide unit 404, motor 403, ball screw 402 and the first slide rail 401.The length bearing of trend of the first slide rail 401 and ball screw 402 and the length bearing of trend of guide rail 102 perpendicular, ball screw 402 and motor 403 are in transmission connection.Slide unit 404 is fixed on the first slide rail 401 slidably, and is in transmission connection with ball screw 402.When ball screw 402 rotates, slide unit 404 can be driven to do straight-line motion along its length.
Slide unit 404 comprises the second slide rail 4041, second sliding tray 4042 and fixed block 4043.Second slide rail 4041 and the second sliding tray 4042 are all fixed on fixed block 4043.Second sliding tray 4042 is fastened on the first slide rail 401 slidably.The sectional dimension of the second slide rail 4041 is identical with the sectional dimension of guide rail 102, and its length bearing of trend is consistent with the length bearing of trend of guide rail 102, like this, when shifting docking mechanism 400 and moving to one end of guide rail 102, second slide rail 4041 matches with guide rail 102, forms straight line.Carry the first sliding tray 1031 controlling the bottom of 103 to match with the second slide rail 4041, when carry control 103 move to transfer docking mechanism 400 time, first sliding tray 1031 is fastened on the second slide rail 4041 slidably, thus will carry control 103 be fixed on transfer docking mechanism 400 on.
As depicted in figs. 1 and 2, pair of guide rails 102 and be placed on the tracks of two of guide rail 102 two ends transfer docking mechanisms 400 composition quadrangles jointly respectively, wherein, the first slide rail 401 of docking mechanism 400 and the length bearing of trend of ball screw 402 and the length bearing of trend of guide rail 102 is shifted perpendicular.Carry and control 103 and be placed on guide rail 102 slidably, accessory to be processed is placed on to carry to be controlled on 103, can control 103 and moves on guide rail 102 along with carrying.Motor 203 on main drive gear 200 rotates thus drives tooth-like belt 201 to rotate by the flute profile wheel 202 be arranged on motor 203.Meshing part 301 on follower 300 engages with the flute profile of tooth-like belt 201, thus makes to carry and control 103 do straight-line motion on guide rail 102.Motor 203 rotates, make to carry control 103 move a certain distance after, stopping operating, thus make to carry and control 103 and accurately stop on corresponding station post, processing carrying the accessory to be processed controlled on 103 to facilitate machine or operator.Motor 203 on transmission device 200 is all connected with control system with the motor 403 on transfer docking mechanism 400, the rotation number of turns of motor 203 is set in the controls by program, make carry control 103 move fixed length distance after, carry control 103 from the end of guide rail 102 shift out be sent to guide rail to the transfer docking mechanism 400 connected, motor 403 work makes the ball screw 402 of transfer docking mechanism 400 do Linear transmission, thus will carry and control 103 and be sent on another guide rail 102.Main drive gear 200 and follower 300 do the same action, complete plane circulation motion.
The plane circulation device of described tooth-like belt transmission utilizes the tooth of equidistantly distribution on tooth-like belt to do transmission, completes plane circulation in the mode that guide rail 102 and transfer docking mechanism 400 combine.Relative to the conveyor line transmission generally used at present, transmission speed and positioning precision are all improved largely, and the cost with timer reduces.Due to carry control 103 with tooth-like belt 201 operationally keep engagement, motor 203 drives tooth-like belt 201 to be with dynamic load to control 103 and directly runs on guide rail 102, carry in the process of movement control 103 can not occurrence positions change, so motor 203 also can not make to carry the positional precision controlling 103 and change by high quick-action row.The transmission speed of this plane circulation device and positioning precision are at least more than three times of existing line transmission mechanism, can be directly used in high speed, high precision processing, and do not need to increase auxiliary positioner.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
