Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chip test seat mounting structure, in particular to a top opening and pressing device for replacing chip test seat Hifix. BACKGROUND

[0002] At present, the existing top opening and pressing chip test seat Hifix replacement mode is generally manual prying, that is, manually using a flat screwdriver to insert into the installation groove on both sides of Hifix, prying Hifix, lifting vertically to make it separate from the chip test seat. The weight of a single Hifix is 5.5 kg. From prying to moving, it will cause certain damage to the operator's body. During the prying process, due to the horizontal difference of both sides, it is easy to damage the Hifix and the clamping groove of the chip test seat. If the screwdriver at one end is not clamped tightly and slides open during prying, the other end will be unevenly stressed and easily pressed. Similarly, when the replaced new Hifix is assembled to the chip test seat, if the clamping groove of Hifix is not accurately inserted or offset, it will cause difficult-to-repair damage to the chip test seat and cause immeasurable economic loss. Therefore, a top opening and pressing device for replacing chip test seat Hifix is provided, which is convenient to replace Hifix, simple to operate, does not cause safety hazards to people, and does not cause damage to Hifix and chip test seat. Therefore, a new technical solution needs to be designed to solve the problem. SUMMARY

[0003] The present application relates to the technical field of chip test seat mounting structure, in particular to a top opening and pressing device for replacing chip test seat Hifix.

[0004] In order to achieve the above object, the application provides the following technical scheme: a top opening and pressing device for replacing chip test seat Hifix, comprising a chip test seat, an upper top plate, an upper pressing plate, an upper needle plate, a limiting rod, and a base hook, wherein a handrail at the bottom of the overall device is manually pressed, the handrail drives the base hook to be embedded into the clamping groove at the bottom of the chip test seat, at this time, the overall device and the chip test seat are positioned and fixed, then the handle is rotated clockwise by hand, the bevel gear vertically placed at the end of the straight shaft of the upper top plate drives the bevel gear horizontally placed, the bevel gear horizontally placed drives the upper pressing plate to move vertically downward under the drive of the transmission rod, the upper needle plate at the bottom of the upper pressing plate is in screw locking structure with the upper pressing plate, when the upper pressing plate moves vertically downward, the upper needle plate also moves downward until the limiting rod of the upper needle plate is inserted into the limiting groove of the Hifix. The limiting rod at the bottom of the upper needle plate and the knob at the top of the upper pressing plate are designed in an integrated manner, when the knob is rotated by 90°, the limiting rod in the limiting groove also rotates by 90°, the bottom of the limiting rod is designed in an elliptical shape, after the limiting rod is rotated by 90°, the limiting rod is also locked and positioned, therefore, when the upper needle plate moves vertically upward, the limiting rod drives the Hifix to also move vertically upward, that is, the Hifix is separated from the chip test seat in the vertical direction, at this time, the top opening operation is completed. Similarly, after replacing the new Hifix, the handle is rotated clockwise by hand again to press the Hifix into the chip test seat, at this time, the Hifix replacement operation of the chip test seat is completed.

[0005] More preferably, in order to change the axial force of the straight shaft into the radial force for replacing the Hifix plate, the application adopts the transmission method that the bevel gear vertically placed at the end of the straight shaft and the bevel gear horizontally placed are engaged with each other, so that the force carrier is changed, which is also the reason why the Hifix can move reciprocally in the vertical direction.

[0006] More preferably, the knob at the top of the upper pressing plate and the limiting rod of the upper needle plate are designed in an integrated manner, in order to rotate the limiting rod inside the device, the knob can be directly rotated to achieve the purpose, which is convenient for positioning the limiting rod in the limiting groove of the Hifix.

[0007] Further description of the foregoing scheme, the bottom of the limiting rod is designed in an elliptical shape, when the limiting rod is inserted into the limiting groove, the limiting rod is rotated by 90°, at this time, the limiting rod cannot be pulled out of the limiting groove, which lays a foundation for the subsequent vertical movement of the Hifix.

[0008] More preferably, when the limiting rod drives the Hifix to move vertically upward to separate from the chip test seat, at this time, the test pin groove at the bottom of the Hifix and the test pin at the top of the chip test seat begin to separate, the overall movement does not deviate in the horizontal direction, and the separation in the vertical direction does not cause damage to the pin or the groove.

[0009] Compared with the prior art, the application has the following advantages:

[0010] The application can conveniently open or press the Hifix from the chip test seat by rotating the handle, and will not cause damage to the Hifix and the test seat, and the bevel gears placed in different directions adopt the transmission mode of mutual engagement, which is convenient and labor-saving. The positioning and locking mode of the oval-shaped limiting rod in the limiting groove provides safety guarantee for the reciprocating movement of the Hifix plate in the vertical direction, and will not cause damage due to falling off.
