Abstract
The utility model relates to a chain pre-drawing running-in machine, which belongs to the field of machine manufacture; the utility model is a necessary device used for pre-drawing running-in treatments in the process of chain manufacture. The utility model is composed of two parts which are respectively a pre-drawing mechanism and a running-in mechanism; the pre-drawing mechanism is composed of a sprocket, a slide block and a rotation force mechanism, wherein, the sprocket is installed on the slide block; the slide block is driven to move along a guide rail on a work table by a force application mechanism; the running-in mechanism is composed of five sprockets with the same type; a pre-drawing chain is installed on the five sprockets; two of the sprockets adopt a coaxial double-sprocket structure; the two sprockets on the lower side are provided with a closed chain; the sprockets are driven by a power device. The utility model adopts a double-fastening, pre-drawing and running-in structure and can realize the continuous processing for pre-drawing chains.
Description
Chain prestretching running-in machine belongs to mechanical manufacturing field.Be to carry out the indispensable equipment that the prestretching running-in is handled during the chain manufacturing is produced.
In the manufacturing production process of chain, the chain that assembles is carried out the prestretching running-in handle, can eliminate erection stress, improve the chain quality, therefore, it is the indispensable technology that improves the chain quality that the prestretching running-in of chain is handled.But because the restriction of equipment, the chain of actual production can only carry out the tentative processing of paragraph prestretching, is difficult to reach state-set standard, and has a strong impact on the quality of production of chain.
The purpose of this utility model is that a kind of chain prestretching running-in machine will be provided, and to finish the prestretching runing complexing process of chain, improves the crudy and the productivity ratio of chain.
The purpose of this utility model is achieved in that this chain prestretching running-in machine is made up of prestretching mechanism and running-in mechanism two parts, prestretching mechanism is to be made of sprocket wheel, slide block, force application mechanism, sprocket wheel is contained on the slide block, slide block is contained on the slide rail of workbench, and slide block is driven and can be moved along slide rail by force application mechanism.Running-in mechanism be by with prestretching mechanism in five sprocket wheels (comprising the sprocket wheel in the prestretching mechanism) of sprocket wheel same model constitute, wherein two sprocket wheels are arranged in the left end of workbench, two sprocket wheels are arranged in the right-hand member of workbench, and place the both sides of the sprocket wheel of prestretching mechanism, five sprocket wheels are same plane, pre-zip strip is contained on each sprocket wheel successively, two sprocket wheels that are arranged in the sprocket wheel both sides in the prestretching mechanism are coaxial double-stranded wheel construction, on two sprocket wheels below it closed chain is housed, this sprocket wheel is driven by power set.
The utility model is to adopt pre-zip strip is carried out two-restriction limit prestretching running-in processing scheme.This scheme not only can be handled continuously to chain, and limit prestretching limit running-in, can effectively eliminate the erection stress in chain assemblies gap, improves the chain assembly quality.This function is eliminated the chain initial stage and is used elongation too fast, and the shortcoming that must adjust in the use reduces noise, improves the service life of chain.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation according to the chain prestretching running-in machine that the utility model proposes.
Fig. 2 is that the K of Fig. 1 is to view.
Fig. 3 is that the AA of Fig. 2 is to view.
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete chain prestretching running-in machine that the utility model proposes.
This machine comprises prestretching mechanism and running-in mechanism two parts, prestretching mechanism has a sprocket wheel (3), and this sprocket wheel is fixed on the slide block (2), and the work top of this machine is provided with slide rail, slide block (2) is driven and can be moved on slide rail by force application mechanism, thereby drives sprocket wheel (3) move left and right.Left end at workbench is equipped with sprocket wheel (5), at the right-hand member of workbench two sprocket wheels (7) is housed, and two sprocket wheels (7) split the both sides in sprocket wheel (3).Sprocket wheel (3) and two sprocket wheels (5), sprocket wheel (7) adopt same model.Two sprocket wheels (7) adopt coaxial double-stranded wheel construction, below closed chain (9) is housed on two sprocket wheels (7 '), rotate synchronously to guarantee two sprocket wheels (7).This sprocket wheel is driven by power set (8).Pre-zip strip (6) is contained on sprocket wheel (3), (5), (7), promptly is contained in successively on sprocket wheel (7), a sprocket wheel (5), sprocket wheel (3), another sprocket wheel (5), another sprocket wheel (7).
The force application mechanism of this machine (1) can adopt spring, weight or mechanism's formula, fluid pressure type.
The prestretching mechanism and the power set (8) of machinery can be controlled by control device (4).Power set can adopt motor.This control device mainly is the running-in speed and the pulling force size of the pre-zip strip of control, can control automatically, also can manually control.
The course of work of this machine is: pre-zip strip (6) is installed to five sprocket wheels (i.e. sprocket wheel (3) successively, two sprocket wheels (5), two sprocket wheels (7)) on, sprocket wheel (7) (7 ') rotates under the driving of power set (8), drive pre-zip strip (6) and on sprocket wheel, carry out running-in, force application mechanism (1) starts simultaneously, and pulling slide block (2) promptly drives sprocket wheel (3) and moves to right, and makes the stressed F of pre-zip strip (6)
1, F
2, F
1=F
2The force application mechanism application of force is neglected the chain specification greatly and is decided, and the time of pre-zip strip prestretching running-in is adjusted to satisfy the prestretching seating time of regulation by power set stepless speed regulation.The pre-zip strip of quilt is spreading constantly, realizes the running-in of continuous uninterrupted prestretching, to satisfy the chain production requirement.
