Abstract
The utility model relates a machine tool accessory, in particular to a transmission device for work piece conveying on the production line. In the single-sprocket multi-spring friction transmission device, one end of a roller shaft is fixedly sleeved with a reducing friction pair; the small-radius part of the reducing friction pair is subsequently sleeved with a single sprocket, a friction pair and a spring friction pair; the spring friction pair is provided with a spring; the other end of the spring is connected with a regulating friction pair; the regulating friction pair is sleeved with the roller shaft; the single sprocket is connected with a chain; the chain is arranged in a guide plate, and the guide plate is connected with a wall panel. The double-sprocket single-spring friction transmission device has novel structure, and solves the problems of the service life and the adjustment of the prior release raceway friction pair, adjusts the friction force of the friction pair on the single roller shaft, thereby determining the diameter of the roller on demand without the restriction of the friction pair; the driving of the single sprocket is limited and guided by the guide plate; the transmission is directly convenient; the structure is compact; and the installation and maintenance are convenient.
Description
One, technical field:
The utility model relates to machine tool accessories, especially for the driving device of manufacturing line workpiece conveying.
Two, background technology:
At present, the manufacturing line collection is put the conveying of formula raceway, and its method that realizes the collection playing function generally has two kinds.A kind of is edge oil-containing powder metallurgy lining in roller, free-running fit between lining and the axle, and when workpiece was blocked by stock stop, roller did not change and has only axle idle running, realizes collecting playing function; When stock stop was decontroled, axle drove the roller rotation by lining, realizes the workpiece conveying function.Another kind is to add spring and friction pair at the roller end face, adjusts spring pressure, and when workpiece was blocked by stock stop, roller did not change and has only axle idle running, realizes the collection playing function; When stock stop was decontroled, axle drove the roller rotation by spring and friction pair, realizes the workpiece conveying function.When first method is put when collection, easily cause oil-containing powder metallurgy lining localized wear, when serious roller can't be rotated, and make raceway lose function.It is very big that second method is needed by friction pair structure influence roller diameter, the equipment cost height, and big some occasion of volume can't be used because of the space reason, need adjust each last two roller friction force in addition respectively, has increased a large amount of adjusting work amounts.
Three, summary of the invention:
The purpose of this utility model is to address the above problem, and provides a kind of strand to take turns many springs friction gear, and simple in structure, volume is little, easy to adjust and long service life.
The technical scheme that the utility model is adopted for achieving the above object is: strand is taken turns many springs friction gear, roller shaft one end fixed cover is equipped with the reducing friction pair, reducing friction pair path part is set with strand wheel, friction pair, spring friction pair successively, spring friction pair built-in spring, the spring other end is connected with the adjusting friction pair, regulate friction pair and be sleeved on the roller shaft, the strand wheel links with chain.
Described chain places in the guide plate, and guide plate and wallboard link.
Described spring friction pair is the body that has annular groove, and body annular groove inwall is placed spring less than outer wall in the annular groove, and the spring other end is connected with the adjusting friction pair.
Place 3-6 spring in the described spring friction pair annular groove.
Described adjusting friction pair open slot is fixedly set on the roller shaft by pin
Described roller shaft is by the fixing suit reducing friction pair of pin.
The utility model novel structure has solved collection and has put raceway friction pair life-span and adjustment problem.Realize carrying out on the single roller shaft adjustment of friction pair friction force, therefore can determine the roller diameter size as required, and not limited by friction pair, regulate on the friction pair and have open slot, push away the adjusting friction pair and move axially, make (length of spring compressed) regulate the friction pair open slot and break away from pin, rotation adjusting friction pair angle, select shallow the unclamping of appropriate openings groove depth, thereby adjust the friction pair spring pressure.Friction pair adopts the high-strength, high-anti-friction engineering plastics to make, and has high service life.Many springs number can design according to the application place, with the operation that guarantees workpiece with stop, and the strand wheel drive, and by the spacing guiding of guide plate, transmission direct convenience, compact conformation and convenient for installation and maintenance.
Four, description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the birds-eye view of Fig. 1.
Five, the specific embodiment:
As Fig. 1, strand shown in 2 is taken turns many springs friction gear, workpiece 1 is on roller shaft 2, roller shaft 2 links by bearing and wallboard, by pin 11 fixed covers reducing friction pair 6 is housed on the axis of rolling 2, reducing friction pair 6 paths part is set with strand wheel 3 successively, friction pair 7, spring friction pair 9, spring friction pair 9 is for having the body of axial annular groove, body annular groove inwall is less than outer wall, place 3-6 spring 8 in the annular groove, spring 8 other ends with regulate friction pair 12 and be connected, regulate friction pair 12 and be fixedly set on the axis of rolling 2 terminations by pin 10, strand is taken turns 3 and is connected with chain 4, chain places in the guide plate, and guide plate 5 links with wallboard.
Pushing away the adjusting friction pair during work moves axially, make (length of spring compressed) regulate the friction pair open slot and break away from pin, the friction pair angle is regulated in rotation, select shallow the unclamping of appropriate openings groove depth, thereby adjust the friction pair spring pressure, realize adjusting the angle of regulating friction pair 12, friction force between friction pair 7 and the strand wheel 3 is set to greater than the workpiece dynamic friction and less than the workpiece static friction, driving lower chain 4 transmissions at engine installation, drive 3 rotations of strand wheel, spring friction pair 9, friction pair 7 rotations, by pin 10,11 are fixed on the adjusting friction pair 12 on the axis of rolling, 6 rotations of reducing friction pair, drive the roller shaft 2 captive joint with it and rotate, the roller shaft 2 rotating bands part 1 of starting building advances; If workpiece 1 is blocked, roller shaft 2 does not rotate, and chain 4 drives sprocket wheel 3 empty rotations.Adjust and regulate friction pair 12 angles, can adjust reducing friction pair 6 and friction pair 7 friction force sizes, guarantee that workpiece 1 is blocked, roller shaft 2 does not rotate, and workpiece 1 is decontroled, roller shaft 2 rotations.
