Slot extension fixture, and may extend to other field.
Summary of the invention
The purpose of the utility model is to provide a kind of extension fixtures using cross chute and bevel gear.
Basic technical scheme is: cross chute extension fixture can be divided into straight driven portions and rotate driving part.It is practical
Novel entirety is by support plate, fixture block, the bevel gear of with groove, connecting rod, incomplete bevel gear, motor, cross chute, locking screw
The composition such as mother, gear shaft, incomplete roller gear, rack gear, sliding block.Straight driven portions are by being driven by motor incomplete cylinder
Gear, which is rotated, drives rack linear movement with engaging for rack gear, and the non-slip groove face of rack gear and cross chute is consolidated by screw
Even, sliding block is fixed in the sliding slot of cross chute, is connected with fixture block by connecting rod, and rack gear is to push cross chute and fixture block
Move to predetermined position.The gear shaft of rotate driving part is connected in incomplete roller gear, and incomplete bevel gear passes through tooth
Wheel shaft and bearing are fixed on shell, and the bevel gear of with groove is installed on the supporting plate by bearing, are fixed by locking nut, four
A connecting rod passes through four sinusoidal acceleration type grooves on the bevel gear of with groove and four straight-line grooves in support plate.It is logical
It crosses the rotation of motor-driven gear axis and drives the rotation of incomplete bevel gear, incomplete bevel gear is after the completion of linear motion and with groove
Bevel gear engagement make its rotation, utilize the sinusoidal expansion for accelerating shape groove to complete fixture block and connecting rod thereon.
The beneficial effects of the utility model are:
1. since the redundancy and robustness of connection type ensure that the stability and reliability of process of expansion.
2. different function can be realized by the repacking to fixture block component, such as connection, locked, crawl.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Attached drawing 1: cross chute extension fixture overall schematic；
Attached drawing 2: cross chute extension fixture drive part schematic diagram；
Attached drawing 3: cross chute and fixture block component enlarged drawing；
Attached drawing 4: example diagram is applied in cross chute expansion in spatial cell robot.
In figure: 1 support plate, 2 fixture blocks, the bevel gear of 3 with grooves, 4 connecting rods, 5 incomplete bevel gears, 6 motors, 7 crosses
Sliding slot, 8 locking nuts, 9 gear shafts, 10 incomplete roller gears, 11 rack gears, 12 sliding blocks.
Specific embodiment
The specific structure of the following is further explained with reference to the attached drawings the utility model tool.
The utility model mechanism composition as shown in Figure 1, Figure 2 and Figure 3.Utility model is whole by support plate (1), fixture block
(2), the bevel gear (3) of with groove, connecting rod (4), incomplete bevel gear (5), motor (6), cross chute (7), locking nut
(8), gear shaft (9), incomplete roller gear (10), rack gear (11), sliding block (12) etc. form.Cross chute extension fixture includes
Straight driven portions and rotate driving part.Straight driven portions by motor (6) driving incomplete roller gear (10) by being turned
Dynamic to move along a straight line with band carry-over bar (11) that engages of rack gear (11), the non-slip groove face of rack gear (11) and cross chute (7) passes through spiral shell
Nail carries out connected, and sliding block (12) is fixed in the sliding slot of cross chute (7), is connected with fixture block (2) by connecting rod (4), rack gear
(11) to push cross chute (7) and fixture block (2) to move to predetermined position.The incomplete bevel gear (5) of rotate driving part
It is fixed on shell by gear shaft (9) and bearing, the bevel gear (3) of with groove is installed by bearing on the supporting plate, by locking
Tight nut (8) is fixed, and four connecting rods (4) pass through four sinusoidal acceleration type grooves and branch on the bevel gear (3) of with groove
Four straight-line grooves on fagging (1) are to ensure the path of fixture block (2) radial motion.Turned by motor (6) gear shaft (9)
It is dynamic to drive incomplete bevel gear (5) rotation, incomplete bevel gear (5) after the completion of linear motion with the bevel gear of with groove (3)
Engagement makes its rotation, utilizes the sinusoidal expansion for accelerating shape groove to complete fixture block (2) thereon.
Utility model works process is as follows:
Straight driven portions are engaged by motor (6) driving incomplete roller gear (10) rotation with rack gear (11) will be endless
The rotation of wholecircle stud wheel (10) is converted to the linear movement of rack gear (11), the non-slip groove face of rack gear (11) and cross chute (7)
Carried out by screw connected, so that cross chute (7) be pushed to move along a straight line, sliding block (12) is fixed on the cunning of cross chute (7)
In slot, it is connected with fixture block (2) by connecting rod (4), so that cross chute (7) pushes fixture block (2) to move to predetermined position.Sliding slot
Play four groups of sliding blocks (12) of limitation simultaneously to move radially.Incomplete roller gear (10) is no longer nibbled with rack gear (11) at this time
It closes, linear drives process is completed.Fixture block (2) needs to move radially and completes expansion task after the certain distance that moves along a straight line.
Rotate driving part is started to work at this time, and the incomplete bevel gear (5) of rotate driving part is fixed by gear shaft (9) and bearing
On shell, the bevel gear (3) of with groove is mounted on support plate (1) by bearing, fixed by locking nut (8), four companies
Extension bar (4) passes through four sinusoidal acceleration type grooves on the bevel gear (3) of with groove and four straight line ditches on support plate (1)
Slot is to ensure the path of fixture block (2) radial motion.The bevel gear (3) of incomplete bevel gear (5) and with groove is driven by motor (6)
Engagement starts turning, and 4 sinusoidal acceleration shape grooves are dispersed on the bevel gear (3) of with groove, keep mechanism structure symmetrical and by
Power is balanced, and fixture block (2) synchronization is driven to diametrically reciprocate while the bevel gear (3) of with groove rotates along groove, comes real
The expansion and locking of existing fixture block (2).Incomplete bevel gear (5) and band after fixture block (2) complete to radially expand to positioning
The bevel gear (2) of groove terminates engagement, and the utility model completes expanding.As shown in figure 4, cross chute extension fixture can
It is connect with the outer housing of cellular machineries people using applied in the bindiny mechanism of spatial cell robot.
