Description

Spring limiter

Technical Field

The utility model relates to a mechanical structure for providing height limit, in particular to a limit device for determining the position of a nut when the nut is screwed.

Background

In assembling the loose well wheel apparatus, there is a station where the nut needs to be screwed into place. The current method for controlling the position is to manually measure the position of the nut by using a ruler, and the nut can be screwed to a specified position only by measuring the position for a plurality of times when one nut is screwed.

Disclosure of Invention

In order to improve the working efficiency and the precision, the utility model provides a spring limiter, which has the technical scheme that: the device consists of a base, a guide block, a lifting block, a limiting rotating shaft, a limiting ball, a spring and a spring fixing pin, wherein a shaft through hole and a limiting ball seat hole are formed in the base, and the through hole is communicated with the seat hole; the guide block is vertically arranged on the base, and a dovetail groove is vertically arranged on the side surface of the guide block; the lifting block is provided with a dovetail block structure, the dovetail grooves of the structure correspond to each other, and the lifting block is arranged on the guide block through the dovetail block and can vertically reciprocate along the dovetail grooves; the lifting block is also provided with a spring hole, and the spring is pressed and contracted in the spring hole through a spring fixing pin and is fixed on the base; the limiting rotating shaft is arranged in the shaft through hole and can rotate along the circumference of the shaft through hole, a settlement plane is arranged on the limiting rotating shaft, and the settlement plane and the circumference of the rotating shaft jointly form a limiting profile which is contacted with the limiting ball and adjusts the height of the limiting ball; when the rotating limiting rotating shaft enables the circumferential surface of the limiting outline to be in contact with the limiting ball, the limiting ball is jacked up by the limiting outline to lift the lifting block, so that a gap is formed between the base and the lifting block to play a limiting role.

When the nut is screwed, the limiting rotating shaft of the device is only required to be adjusted so that the circumferential surface of the limiting outline of the limiting rotating shaft is contacted with the limiting ball, thereby lifting the lifting block to form a fixed gap height, and the nut is screwed on the upper surface of the lifting block.

The beneficial effects of the utility model are as follows: the nut can be screwed in place in one step by adopting a fixed limit height structure, so that multiple manual measurement and adjustment are avoided, the nut screwing efficiency is improved, and the accuracy is improved.

In the figure, 1 base, 2 guide blocks, 4 lifting blocks, 3 spacing rotation shafts, 5 spacing balls, 6 springs, 7 spring fixing pins, 11 shaft through holes, 12 spacing ball seat holes, 21 dovetail grooves, 42 dovetail blocks, 41 spring holes, 31 sedimentation planes and 8 gaps.

Detailed Description

As shown in fig. 1, the utility model is composed of a base 1, a guide block 2, a lifting block 4, a limit rotating shaft 3, a limit ball 5, a spring 6 and a spring fixing pin 7, and is characterized in that: the base 1 is internally provided with a shaft through hole 11 and a limit ball seat hole 12, and the through hole is communicated with the seat hole; the guide block 2 is vertically arranged on the base 1, and a dovetail groove 21 is vertically arranged on the side surface of the guide block; the lifting block 4 is provided with a dovetail block 42 structure, the dovetail grooves 21 of the structure correspond to each other, and the lifting block 4 is arranged on the guide block 2 through the dovetail block 42 and can vertically reciprocate along the dovetail grooves 21; the lifting block 4 is also provided with a spring hole 41, and the spring 6 is pressed and contracted in the spring hole 41 through a spring fixing pin 7 and is fixed on the base 1; the limiting rotating shaft 3 is arranged in the shaft through hole 11 and can rotate along the circumference of the shaft through hole 11, a sedimentation plane 31 is arranged on the limiting rotating shaft, and the sedimentation plane 31 and the circumference of the rotating shaft 3 jointly form a limiting profile which is contacted with the limiting ball 5 and adjusts the height of the limiting ball 5; as shown in fig. 2, when the limiting rotation shaft 3 is rotated to make the circumferential surface of the limiting profile contact with the limiting ball, the limiting ball is jacked up by the limiting profile to lift the lifting block 4, so that a gap 8 is formed between the base and the lifting block 4 to perform a limiting function.

When the nut is screwed, the limiting rotating shaft 3 of the device is only required to be adjusted so that the circumferential surface of the limiting outline of the limiting rotating shaft is contacted with the limiting ball, thereby lifting the lifting block 4 to form a fixed height of the gap 8, and the nut is screwed on the upper surface of the lifting block 4.

The foregoing detailed description is given by way of example only and is not to be construed as limiting the scope of the utility model, as it is for the person skilled in the art to better understand the present patent; any alterations or modifications of the present patent disclosure, which are substantially the same or equivalent in technical content, fall within the scope of the present patent.
