Description

A kind of novel B OSA shell-LD press mounting structure and pressing method

Technical field

The present invention relates to a kind of novel B OSA shell-LD press mounting structure and pressing methods.

Background technique

BOSA shell 5 need to be put into pedestal 3 by the structure conventionally used for LD press fitting when as shown in Figure 1, being pressed, upper cover 2 It covering on pedestal 3, LD4 is put into 2 the inside of upper cover, and 1 set of pressure head is put into pressure mechanism press fitting position on LD4, by tooling, Pressure mechanism is triggered, after completing press fitting movement to pressure mechanism, tooling need to be removed from press fitting position, take out pressure head 1, take out Upper cover 2 takes out LD4 and 5 component of BOSA shell, completes the press fitting of single product.Whole process needs 10 steps to complete, to personnel It is required that high and labor intensity is larger.

Components in Fig. 1 respectively indicate as follows:

Serial number	Title	Serial number	Title
				1	Pressure head	4	LD component
2	Upper cover	5	BOSA shell
				3	Pedestal

Summary of the invention

The shortcomings that in order to overcome the prior art, the present invention provides a kind of novel B OSA shell-LD press mounting structure and press fittings Pedestal, pressure head, limit for height block, press fitting inclined-plane etc. are fully integrated as an entirety, are realized between tooling by contained spring by method Separation, operating procedure is simple, reduces dependence to operator.

The technical scheme adopted by the invention is that: a kind of novel B OSA shell-LD press mounting structure, including L-type pedestal and in L The linear guides being arranged on type pedestal vertical direction, are arranged hold on linear guides, and fixed press fitting is oblique below hold Face and limit for height block；Pressure head is set on the horizontal base of L-type pedestal, resilient sleeve is arranged in pressure head upper end, in resilient sleeve outer cover It limits high pedestal.

The present invention also provides a kind of novel B OSA shell-LD pressing methods, include the following steps:

Step 1: LD pin is put into pressure head downwards, it is ensured that the bottom surface LD is bonded with pressure head end face, and resilient sleeve is to LD Outer circle realizes positioning；

Step 2: BOSA shell is put into resilient sleeve, BOSA shell realizes the concentric locating with LD by resilient sleeve；

Step 3: external pressure mechanism acts on pressure block, pressure block pushes hold to transport straight down along linear guides It is dynamic, during pushing, it is pressed ramp effect on BOSA shell, pushes BOSA shell that chip is pressed into BOSA shell when moving down In body；

Step 4: being depressed into position when limit for height block and limit for height pedestal are adjacent to, then pressure mechanism resets, and reset spring pushes Restoring link drives hold to return to initial position straight up along linear guides, takes out BOSA component, and single press fitting is completed.

Compared with prior art, the positive effect of the present invention is: in the case where guaranteeing to be pressed height and levelness, realizing : optimization press fitting operating procedure reduces the dependence to personnel；In production process, quickly cut between the BOSA shell of different length It changes；As press pack modules, manually and automatically between independent assortment.Specific manifestation is as follows:

1, single is pressed process, and the prior art needs 10 steps to complete, and the present invention only needs 4 steps with regard to achievable；

2, when producing the BOSA shell of different length, the prior art needs replacing the press-fitting tool of corresponding product, inhomogeneity Other tooling needs separate management, and the present invention only needs to change limit for height block in switching, remaining tooling is constant, while being switched fast Facilitate the centralized management of tooling；

3, in terms of equipment utilization, the prior art is confined to manual hand manipulation, and Fixture Design is one by the present invention Integral module multiple can also be laid out and be automatically brought into operation in equipment, using upper more flexible individually for manual hand manipulation Property.

Specific embodiment

1, a kind of novel B OSA shell-LD press mounting structure, as shown in Figure 2 and Figure 3, components respectively indicate as follows:

Serial number	Title	Serial number	Title
				1	Pressure block	7	Resilient sleeve
2	Hold	8	Limit for height pedestal
				3	It is pressed inclined-plane	9	Elastic upper cover
4	Limit for height block	10	Pressure head
				5	Linear guides	11	Reset spring
6	L-type pedestal	12	Restoring link

Wherein:

Reset spring 11 is placed in 6 lateral inner of L-type pedestal, linear guides 5 are set in 6 vertical direction of L-type pedestal, online Property guide rail 5 on be arranged hold 2, pressure block 1 is placed on hold 2, in 2 side fixed reset connecting rod 12 of hold, under Fixed press fitting inclined-plane 3 and limit for height block 4 below pressure arm 2；Pressure head 10 is set on L-type pedestal 6, is arranged resilient sleeve in 10 upper end of pressure head 7, elastic upper cover 9 is set on 7 pedestal of resilient sleeve, and the elasticity upper cover 9 is fixed on pressure head 10, is arranged in elastic upper cover 9 Limit for height pedestal 8, the limit for height pedestal 8 are set in outside resilient sleeve 7.

For the structure of the pressure block 1 as shown in figure 4, the pressure block top is disk, lower part is cylinder, the cylinder of lower part Protrude into hold, the function of realization is: external pressure mechanism will act on this part, such damage parts it is can be changed quickly and The assembly of other components is not influenced.

The structure of the hold 2 is as shown in figure 5, the function of realizing is: driving press fitting inclined-plane 3 as structure upper main body It moves up and down with limit for height block 4.

The structure on the press fitting inclined-plane 3 is as shown in fig. 6, the function of realizing is: ensuring to be face contact between shell and be Meet the angle of technique requirement.

The structure of limit for height block 4 is as shown in fig. 7, the function of realizing is: limitation tooling pushes height, toroidal design increase contact Area and range, it is easier to guarantee the depth of parallelism after pushing.

As shown in figure 8, the limit for height block is the annulus with opening, the function of realization is the structure of the linear guides 5: Ensure that upper mechanism is for linear motion and repeats position precision when pressing.
