Description

Technical Field

[0001] The invention belongs to the technical field of magnetic disk equipment, and in particular relates to a variable fixed-floating process gasket inserting mechanism. Background Art

[0002] The HSA punching process for hard disk read / write heads has always used a fixed-position punching process gasket to fill the gap between the drive rack arms. Since the process gasket is fixed and idle in the upper and lower positions, if there is a material difference (dimensional tolerance) in the drive rack arm, the gap cannot be completely filled. When the drive rack arm is pre-pressed before punching, the process gasket will deform, resulting in the drive rack not being completely filled flat, which deviates from the technical requirements of solid punching. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a variable fixed-floating process gasket insertion mechanism, which can avoid damage to the drive frame support arm during insertion and realize the up and down floating state of the process gasket through the boss matching mechanism.

[0005] As a further technical solution of the present invention, a fixed positioning groove is arranged in the gasket guide groove, and floating positioning grooves are arranged at the outer end and the inner middle end thereof respectively, and the height of the floating positioning groove is greater than the height of the fixed positioning groove; the length between the floating positioning grooves is longer than the length between the first boss and the second boss on the gasket.

[0006] Furthermore, the section from one end of the gasket close to the connecting hole to the middle section of the first boss is a hand-holding part, and the section from the middle section of the first boss to the other end of the gasket is a plug-in part, and the width of the hand-holding part is smaller than the width of the plug-in part; the thickness of the hand-holding part is 0.85 mm, the thickness of the plug-in part is 1.15 mm, and the thickness of the first boss and the second boss is 1.15 mm.

[0007] Furthermore, the second connecting arm is inserted into the guide groove of the gasket driving mechanism, and the side of the gasket guiding mechanism away from the guide groove of the gasket driving mechanism is fitted with the inner side of the first connecting arm, and the inner side of the gasket guiding mechanism is fitted with the inner side of the gasket driving mechanism, so that the gasket guiding mechanism and the gasket driving mechanism are clamped.

[0008] Furthermore, one end of the gasket locking pin is a fixed end, the diameter of the main body of the gasket locking pin is the same as the inner diameter of the gasket driving mechanism pin hole and the gasket guide mechanism pin hole, and the diameter of the fixed end is larger than the diameter of the gasket driving mechanism pin hole.

[0009] Furthermore, the number of the gasket guide grooves is 10, the number of the gaskets is 10, the connecting holes on the gaskets are elliptical, and the diameter of the gasket pin holes on the gaskets is larger than the main body diameter of the gasket locking pin.

[0010] Furthermore, a fixing structure is arranged on one side of the gasket guide mechanism close to the guide groove of the gasket drive mechanism, and a plurality of fixing holes are arranged on the fixing structure.

[0011] The advantage of the present invention is that the height of the gasket is fixed before it is inserted into the drive frame through a mechanical structure, ensuring that the drive frame support arm will not be damaged during insertion. Once the process gasket is in place, the process gasket can float up and down through the boss matching mechanism. The influence of the material difference of the drive frame support arm can be perfectly compensated to ensure that the gap between the support arms is completely filled and fully compacted.
