It is controllable with precision, avoid hand assembled pin from causing error to product quality.But its structure is complex, is not suitable for
It is assembled with certain depth and narrow space.
Patent of invention " a kind of pin automatic assembling dress of lockset that State Intellectual Property Office's on January 22nd, 2014 announces
Set ", application number: 201310470855.6, content also with the application relatively.The present invention relates to a kind of processing of lockset to set
It is standby, comprising: pedestal and the stamping device being mounted on the base, lock body feed device, pin feed device.The pin of the lockset is certainly
Dynamic assembly device, assembling process are as follows: 1, it clamps cylinder and lock body sliding clamp is driven to move in lock body workpiece installation position, when assembly
Lock body workpiece to be processed is put into lock body workpiece installation position, lock body sliding clamp shifts lock body workpiece on lock body fixed chuck onto
And be fixed, at this point, lock body workpiece is located just at the underface of formed punch；2, feeding cylinder drives delivery sheet to be moved forward and backward, and send
Pin in feed pipe is transported to immediately below formed punch by the feeding port on flitch；3, punching cylinder drives formed punch to move downward, formed punch
Pin on delivery sheet is fixed in the lock body workpiece on lock body fixed chuck, assembly is completed.The pin of the lockset fills automatically
It is only capable of being suitable for lockset and a kind of specific purpose tool with device.It is not suitable for the assembly of other machinery components.
For these reasons, it is necessary to which, according to the concrete condition of current machinery enterprise Product Assembly, designing one kind can expire
Foot is asked in the device of Space configuration elastic cylindrical pin narrow or that have certain depth with solving assembly difficulty in the prior art
Topic.
Utility model content
Simple, safe operation that the purpose of this utility model is to provide a kind of structures convenient for assembly is used for small space
Or the device of the elastic cylindrical pin assembly of certain depth, it reduces because complicated fixed form increases artificial and cost of parts, lowers dress
With insecurity in the process, the simple and quick assembly of elastic cylindrical pin in different model tractor assembling process is realized, guarantee
The production efficiency and assembling quality of tractor chassis assembly.
The technical solution of the utility model is: a kind of device assembled for elastic cylindrical pin in small space, comprising: top
Bar, spring, cylindrical matrix, magnet ring；Cylindrical matrix is hollow cylinder, and cylindrical matrix one end is provided with magnet ring counterbore, cylinder base
The body other end is provided with spring counterbore, and magnet ring is embedded in magnet ring counterbore, and the mandril for being set with spring is inserted into from spring counterbore to be justified
In base for post body.
The following length in mandril head is equal to cylindrical matrix length.
The drift of spring is 2a, and stretching cylindrical matrix outer length is a, and spring counterbore internal diameter is greater than spring outer diameter,
Spring counterbore depth is equal to spring and stretches out cylindrical matrix outer length a.
The outer diameter and length of magnet ring are equal to the internal diameter and depth of magnet ring counterbore.
The utility model can achieve following good effect afterwards by adopting the above technical scheme: can fix two matched
Part is reduced because complicated fixed form increases artificial and cost of parts.It avoids in assembly and is directly contacted with part percussion, improved
The safety of assembly reduces a possibility that safety accident occurs.Using the similar bullet of same principle production different model
Property straight pin assembly device.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the device assembled for elastic cylindrical pin in small space of the utility model.
In figure: 1- mandril, 2- spring, 3- cylindrical matrix, 4- magnet ring.
Specific embodiment
The utility model is further detailed below by accompanying drawings and embodiments.It is a kind of as shown in Figure 1: to be used for bullet
The device that property straight pin is assembled in small space, comprising: mandril 1, spring 2, cylindrical matrix 3, magnet ring 4.Cylindrical matrix 3 is hollow
