Technical Field

The invention relates to the field of testing fixture equipment, in particular to a buffer structure of a testing fixture.

Background

The checking fixture is a simple tool for controlling various sizes (such as aperture, space size and the like) of products, and improves production efficiency and control quality. In order to avoid interference in the process of loading parts and inspecting, the turnover mechanism is the most common structure on the inspection tool. In the use process of the turnover mechanism, the detection block is heavy, so that the weightlessness phenomenon can occur, and the long-time weightlessness can cause the deformation and the abrasion of the limit block. It becomes important to solve this problem.

Disclosure of Invention

The invention aims to provide a buffer structure of a checking fixture, which is characterized in that a buffer is additionally arranged on the right side of a bracket and buffers a turnover arm from the lower side, so that the collision between the turnover arm and a limiting block is reduced, and the problem of deformation and abrasion of the limiting block caused by the weight loss of the existing turnover arm is solved.

The invention provides a buffer structure of a checking fixture, which comprises a bracket, wherein an overturning arm is arranged at the upper end of the bracket, the left end of the overturning arm is connected with the bracket through a rotating shaft, a detection block is arranged at the left end of the overturning arm, a buffer is arranged at the upper end of the right side edge of the bracket, the upper end of the buffer is contacted with the lower side of the overturning arm, and a limit block is arranged at the right side of the upper end of.

The further improvement lies in that: the limiting block is provided with a buffer cushion.

The further improvement lies in that: the rotating shaft is sleeved with a torsional spring, and two ends of the torsional spring are respectively connected with the bracket and the turnover arm.

The further improvement lies in that: the upper side of the turnover arm is provided with an adjusting bolt.

The invention has the beneficial effects that: the buffer is additionally arranged on the right side of the bracket and buffers the overturning arm from the lower side, so that the collision loss between the overturning arm and the limiting block is reduced, and the service life is prolonged; the torsional spring is added, the impact force of the weightless falling of the turnover arm is reduced, and the buffering effect is effectively improved.

Wherein: the device comprises a bracket 1, a turnover arm 2, a rotating shaft 3, a buffer 4, a limiting block 5, a buffering pad 6, a torsion spring 7 and an adjusting bolt 8.

Detailed Description

For the purpose of enhancing understanding of the present invention, the present invention will be further described in detail with reference to the following examples, which are provided for illustration only and are not to be construed as limiting the scope of the present invention.

As shown in fig. 1, the present embodiment provides a buffer structure for a checking fixture, which includes a bracket 1, wherein an overturning arm 2 is disposed at an upper end of the bracket 1, a left end of the overturning arm 2 is connected to the bracket 1 through a rotating shaft 3, a detection block is mounted at a left end of the overturning arm 2, a buffer 4 is mounted at an upper end of a right side edge of the bracket 1, an upper end of the buffer 4 is in contact with a lower side of the overturning arm 2, and the buffer 4 buffers a falling of the overturning arm 2; the right side of the upper end of the bracket 1 is provided with a limiting block 5. Be equipped with blotter 6 on stopper 5, blotter 6 cushions protection to stopper 5. The rotating shaft 3 is sleeved with a torsion spring 7, two ends of the torsion spring 7 are respectively connected with the bracket 1 and the turnover arm 2, and the torsion spring 7 is compressed and buffered in a limited manner when the turnover arm 2 is weightless, so that the impact force of weightless falling is reduced. An adjusting bolt 8 is arranged on the upper side of the turnover arm 2, so that the turnover arm 2 and the bracket 1 are fixed.

When the overturning arm 2 is subjected to weightlessness and suddenly falls down, the buffer 4 is impacted by external force to drive the piston to extrude hydraulic oil in the inner pipe, the hydraulic oil is discharged from an oil discharge hole of the inner pipe after being pressed, and meanwhile, the hydraulic oil discharged from the inner pipe also flows back to the inner pipe from an oil return hole of the inner pipe; when the external force disappears, the spring rebounds the piston to the initial point to wait for the next action. The turnover mechanism can achieve longer service life.
