Abstract

The utility model relates to a pressurized curing clamp, which comprises a frame, a screw rod and a strain gauge, wherein the upper end of the frame is provided with a circular hole, the screw rod passes through the circular hole to stretch into the frame, the lower end of the screw rod is provided with a bearing, the lower end of the screw rod is connected with an inner ring of the bearing, an outer ring of the bearing is connected with a support, the lower end of the support is connected with a sliding iron block, the upper end and the lower end of the strain gauge are respectively provided with a first high temperature resisting rubber gasket and a second high temperature resisting rubber gasket, the upper end of the first high temperature resisting rubber gasket is connected with the sliding iron block, the lower end of the second high temperature resisting rubber gasket is connected with the bottom part of the frame, and an elastic body is arranged at the periphery of the side of the strain gauge. The utility model has the beneficial effects that the clamp is applied to the high temperature pressurized curing step of the pasting of the later-stage working procedure of the strain gauge; as the toque force is eliminated, the strain gauge becomes more even, the impedance change caused by the deformation can be more uniform, further, the precision of the measurement of a product is greatly improved, the rejection rate can be reduced, and the manufacture cost is reduced.

Description

A kind of cure under pressure anchor clamps
Technical field
The utility model relates to a kind of cure under pressure anchor clamps.
Background technology
Strain ga(u)ge is the core component of LOAD CELLS.Strain gauge is attached at and has just become the LOAD CELLS that weight is converted to the signal of telecommunication on the elastomer, becomes the core of electronic scale.Wherein in the high-temperature pressurizing curing schedule of strain gauge paster later stage operation, the clockwise torsion of the horizontal direction that screw rod spin friction clamping plate produce, this torsion can cause the strain gauge bending, fold, certainty of measurement reduces, and serious meeting causes product rejection, has strengthened the manufacturing cost of product.
The utility model content
The purpose of this utility model provides a kind of cure under pressure anchor clamps, in the high-temperature pressurizing curing schedule that overcomes prior art strain gauge paster later stage operation, because the clockwise torsion of the horizontal direction that screw rod spin friction clamping plate produce, this torsion can cause the strain gauge bending, fold, certainty of measurement reduces, and serious meeting causes the deficiency of product rejection.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of cure under pressure anchor clamps, comprise framework, screw rod and strain gauge, the upper end of described framework is provided with circular hole, described screw rod passes circular hole and stretches into framework inside, the lower end of screw rod is provided with bearing, the inner ring of the lower end connection bearing of screw rod, the outer ring of bearing is connected with support, the lower end of support is connected with the slip iron block, the two ends up and down of described strain gauge are respectively equipped with the first high-temperature resistant rubber pad and the second high-temperature resistant rubber pad, first high-temperature resistant rubber pad upper end connects the slip iron block, the bottom of the lower end connecting frame of the second high-temperature resistant rubber pad, and the strain gauge side periphery is provided with elastomer.
The beneficial effects of the utility model are: adopt these anchor clamps to be used for the high-temperature pressurizing curing schedule of strain gauge paster later stage operation, owing to eliminated torsion, it is more smooth that strain gauge becomes, and the impedance variations that generation deformation causes is more even, and the certainty of measurement of product is promoted greatly, the employee need not be meticulous again in operation, on tenterhooks, the good operation phychology has been arranged, efficient just can promote greatly, and reduced scrappage, reduced manufacturing cost.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the described cure under pressure clamp structure of a utility model embodiment schematic diagram;
Fig. 2 is the structural representation that adds press in the described original cure under pressure step of the utility model embodiment.
Among the figure:
1, framework; 2, circular hole; 3, screw rod; 4, bearing; 5, inner ring; 6, outer ring; 7, support; 8, slip iron block; 9, strain gauge; 10, the first high-temperature resistant rubber pad; 11, the second high-temperature resistant rubber pad; 12, elastomer.
The specific embodiment
Shown in Fig. 1-2, the described a kind of cure under pressure anchor clamps of the utility model embodiment, comprise framework 1, screw rod 3 and strain gauge 9, the upper end of described framework 1 is provided with circular hole 2, described screw rod 3 passes circular hole 2 and stretches into framework 1 inside, the lower end of screw rod 3 is provided with bearing 4, the inner ring 5 of the lower end connection bearing 4 of screw rod 3, the outer ring 6 of bearing 4 is connected with support 7, the lower end of support 7 is connected with slip iron block 8, the two ends up and down of described strain gauge 9 are respectively equipped with the first high-temperature resistant rubber pad 10 and the second high-temperature resistant rubber pad 11, the first high-temperature resistant rubber pad, 10 upper ends connect slip iron block 8, the bottom of the lower end connecting frame 1 of the second high-temperature resistant rubber pad 11, strain gauge 9 side periphery are provided with elastomer 12.
During use; in the high-temperature pressurizing curing schedule of 9 paster later stage of strain gauge operation; screw rod 3 turns clockwise; pass circular hole 2; the bearing 4 of lower end is moved straight down; the inner ring 5 of bearing 4 turns clockwise with screw rod 3; outer ring 6 horizontal directions of bearing 4 are not rotated; move straight down with bearing 4; the lower end that drives support 7 is connected with slip iron block 8 to lower slider, can eliminate a big chunk like this owing to fricative torsion, thereby protect fragile strain gauge; by the first high-temperature resistant rubber pad 10, give strain gauge 9 downward pressure.Meet the tendency in the high-temperature pressurizing curing schedule of 9 paster later stage of strain gauge operation by this kind anchor clamps, product rejection rate is reduced to 0.9%, use original anchor clamps, reduced scrappage, reduced manufacturing cost because of the scrappage of strain gauge distortion is 3%; Owing to eliminated torsion, it is more smooth that strain gauge becomes, the impedance variations that generation deformation causes is more even, the certainty of measurement of product is promoted greatly, improved the competitiveness of produce market, the employee need not be meticulous again, on tenterhooks in operation, the good operation phychology has been arranged, and efficient just can promote greatly.
