Description
Technical field
The utility model relates to a kind of speed change gear, particularly a kind of speed change gear of adjustable feed length.
Background technique
Reinforcing bar, steel band class section bar are the steel that a kind of output is large, purposes is wide, wide in variety, especially apply very wide in building and mechanical processing industry.Reinforcing bar, steel band class section bar, in process of manufacture, need production and processing to go out the product of different length or diameter, and the speed change gear of adjustable feed length just seems particularly important in such machinery.On Vehicles Collected from Market, main use electrical control realizes this type of function, but this can cause equipment frequent starting, impacts comparatively large, thus causes quality of product to decline, also hand over seriously equipment self-inflicted injury.Some mechanical speed change gears that market also exists, but its structure is too complicated, and cost is too high, and rate of fault is higher, is not suitable in the high capacity equipment of this production and processing reinforcing bar, steel band class section bar.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of speed change gear of adjustable feed length, and structure is simple, cheap, working stability, bearing capacity are strong.
The technological scheme that the utility model is taked is:
A speed change gear for adjustable feed length, comprises cam drive axle, line shaft, sliding axle, and speed-changing chain is arranged on cam drive axle, and multi-speed sprocket is arranged on line shaft, regulates sprocket wheel to be arranged on sliding axle.Described sliding axle is installed on the control panel, and sliding axle is connected with Compress Spring one end, and the Compress Spring the other end is fixing on the control panel.
Adjusting screw rod one end is fixing on the control panel, and the adjusting screw rod the other end is provided with L-type rocking handle.
Described control panel is provided with sprocket channel, and adjustment sprocket wheel and the one section of chain be engaged with all are positioned at sprocket channel.Ensure that in speed regulation process, chain exactly on multi-speed sprocket different-diameter sprocket wheel between convert.
Described control panel offers chute, and sliding axle is arranged in chute.
Described sliding axle end is flat, and chute is U-type groove, and sliding axle can translation in chute, and can not rotate.
Described control panel is by upper fulcrum, the fixed installation of lower fulcrum.
The speed change gear of a kind of adjustable feed length of the utility model, control panel is moved around, thus drive the adjustment sprocket wheel translation be back and forth arranged on speed Control panel, regulate the translation of sprocket wheel make chain can with the sprocket engagement of different-diameter on multi-speed sprocket, to change the velocity ratio of this device, thus realize the speed changing function of this device.
The speed change gear of a kind of adjustable feed length of the utility model, structure is simple, cheap, working stability, bearing capacity are high, be mainly used in the manufacturing and processing equipment of reinforcing bar, steel band class section bar, support the use with the indexing mechanism in this kind equipment, by regulating the velocity ratio of speed change gear, thus realize the different interval duration of indexing mechanism, change the adjustable function of feed length to reach.
Accompanying drawing explanation
Fig. 1 is the utility model apparatus structure schematic diagram.
Fig. 2 is the utility model device speed-changing chain, multi-speed sprocket structural representation.
Embodiment
As shown in Figure 1 and Figure 2, a kind of speed change gear of adjustable feed length, comprises cam drive axle 2-6, line shaft 2-1, sliding axle 4-2, and cam drive axle 2-6, line shaft 2-1 are installed in frame.Speed-changing chain 2-35 is arranged on cam drive axle 2-6, and multi-speed sprocket 2-9 is arranged on line shaft 2-1, regulates sprocket wheel 4-1 to be arranged on sliding axle 4-2.Described sliding axle 4-2 is arranged on control panel 4-4, and sliding axle 4-2 is connected with Compress Spring 4-6 one end, and the Compress Spring 4-6 the other end is fixed on control panel 4-4.Adjusting screw rod 4-9 one end is fixed on control panel 4-4, and the adjusting screw rod 4-9 the other end is provided with L-type rocking handle 4-10.Described control panel 4-4 is provided with sprocket channel 4-3, and adjustment sprocket wheel 4-1 and the one section of chain be engaged with all are positioned at sprocket channel 4-3.Described control panel 4-4 offers chute 4-5, and sliding axle 4-2 is arranged in chute 4-5.Described sliding axle 4-2 end is flat, and chute 4-5 is U-type groove, and sliding axle 4-2 can translation in chute 4-5.Described control panel 4-4 is fixedly mounted by upper fulcrum 4-7, lower fulcrum 4-8, and upper fulcrum 4-7, lower fulcrum 4-8 are installed in frame.
Working principle: for the speedup of this device, be rotated counterclockwise L-type rocking handle 4-10, control panel 4-4 is moved right, being arranged on sprocket channel 4-3 on control panel 4-4 and sliding axle 4-2 along with control panel 4-4 moves right, be arranged on adjustment sprocket wheel 4-1 the moving right along with sliding axle 4-2 on sliding axle 4-2, under the effect that sprocket channel 4-3 moves right together with adjustment sprocket wheel 4-1, chain is pushed away to the right, along with the rotation of multi-speed sprocket 2-9 and speed-changing chain 2-35, chain is transitioned on the larger one-level sprocket wheel of diameter on the right of multi-speed sprocket 2-9 stably, thus achieve the increase of velocity ratio between multi-speed sprocket 2-9 and speed-changing chain 2-35, namely the function of speedup is reached.
This speed change gear coordinates intermittent feeding device, and the interval duration that can be reduced intermittent feeding mechanism by the speedup of this speed change gear shortens the length of interval feeding each time.This speed change gear slows down as the same.In this process, regulate sprocket wheel 4-1 also to play a part Idle wheel simultaneously, when chain sprocket wheel transition more higher leveled toward multi-speed sprocket 2-9, chain is tauted, sprocket wheel 4-1 is regulated to do perpendicular to the outside movement of paper together with sliding axle 4-2, Compress Spring 4-6 is compressed simultaneously, and ensure that chain is when the sprocket engagement with different-diameter on multi-speed sprocket 2-9, the tensioning degree of chain is constant.
