Abstract
The utility model discloses a vibrating stress relief device for a vernier caliper, relating to the technical field of machining equipment. The vibrating stress relief device comprises a vibration exciter, a vibration pickup and a platform, wherein a plurality of T-shaped grooves arranged in parallel are formed in the surface of the platform; at least three T-shaped bolts are arranged in each T-shaped groove; a press plate is arranged outside each T-shaped bolt in a penetrating way; the vibration exciter is fixed on the surface of the platform, which is positioned at one end of the T-shaped groove; and the vibration pickup is arranged on the surface of the platform, which is positioned at the other end of the T-shaped groove. Compared with the prior art, the simpleness in clamping is realized and the residual stress inside a caliper body can be effectively eliminated in batches; the tracking detection of bodies of 1000 vernier calipers subjected to vibrating stress relief treatment is realized by using the vibrating stress relief device for the vernier caliper; and after the assembled vernier caliper is placed for a period of time, the bent deformation of a body of the vernier caliper in the length direction and the twisting deformation of the body in the width direction are avoided.
Description
Technical field
The utility model relates to machining equipment manufacturing technology field, especially a kind of device for vernier callipers being carried out the oscillating aging processing.
Background technology
Vernier callipers is a kind of high-precision length measuring instrument, and it is by vernier callipers blade and forming at the chi frame that the vernier callipers blade slides; The vernier callipers blade is the workpiece of long slim " T " font, the manufacturing of vernier callipers blade under expect that making finished product will pass through ten multiple working procedures such as heat-treatment quenching, welding, milling, grinding; The vernier callipers that assembles is after placing for some time, the flexural deformation of length direction and the torsional deformation of width can appear in the vernier callipers blade, and these are because the vernier callipers blade causes in the unrelieved stress that the processing of carrying out series of processes produces afterwards; Unrelieved stress has a significant impact the working accuracy of vernier callipers blade and the stability of dimensional precision, needs to eliminate its unrelieved stress.Being used for eliminating unrelieved stress institute employing method has natural aging, Heat artificially ageing treatment and oscillating aging to process three kinds of methods usually, and natural aging does not generally adopt because the time is long; Although the Heat artificially ageing treatment can be eliminated the unrelieved stress of blade inside, the hardness that can reduce the vernier callipers blade up to the aging temp about 550 ° of C generally will not adopt; The vernier callipers blade just carries out temper behind heat-treatment quenching at present, and this also can only eliminate a part because cooling off rapidly the unrelieved stress that causes.Oscillating aging is to reduce the also unrelieved stress of homogenizing inside parts by the method that applies vibration, thereby improves the working strength of part, stabilizer elements size and geometric accuracy; The minimum natural frequency of vernier callipers blade is greater than the maximum excited frequency of vibration ageing device, need to adopt a kind of device that the vernier callipers blade is carried out down conversion process, and choose suitable exciting point and vibrational frequency and could carry out oscillating aging to the vernier callipers blade and process, in existing Vibration Aging Process, also there is not a kind of vibration ageing device to go for above-mentioned vernier callipers blade.
The utility model content
It is simple that the technical problems to be solved in the utility model provides a kind of clamping, can effectively eliminate the vernier callipers vibration ageing device of vernier callipers blade internal residual stress.
The technical scheme that the utility model technical solution problem adopts is: this vernier callipers vibration ageing device includes vibrator and oscillation pickup, a platform is arranged, table top at described platform is provided with many T-shaped grooves that be arranged in parallel, in the described T-shaped groove of each bar at least three T-shaped bolts are housed, each T-shaped bolt is coated with a block pressur plate outward; Described vibrator is fixed on the table top of an end that described platform is positioned at described T-shaped groove, and described oscillation pickup is placed on the table top of the other end that described platform is positioned at described T-shaped groove.
Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect: 1, clamping is simple, can effectively eliminate in batches the unrelieved stress of blade inside; 2, carry out the vernier callipers blade tracking detection that oscillating aging is processed to 1000 with this vernier callipers vibration ageing device, the vernier callipers that assembles is after placing for some time, and the flexural deformation of length direction and the torsional deformation of width do not appear in the vernier callipers blade.

Fig. 2 is the sectional view at Fig. 1 A-A place.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Vernier callipers vibration ageing device as shown in Figure 1 and Figure 2 includes vibrator 1 and oscillation pickup 6, and a platform 2 is arranged, and the length of platform * wide * height is 3600 * 1200 * 200 millimeters; Table top at platform 2 is provided with many T-shaped grooves that be arranged in parallel, and three T-shaped bolts 4 are housed in the T-shaped groove of each bar, each T-shaped bolt 4 outer block pressur plate 3 that are coated with; Vibrator 1 is fixed on the table top of an end that platform 2 is positioned at T-shaped groove, and oscillation pickup 6 is placed on the table top of the other end that platform 2 is positioned at T-shaped groove; Many vernier callipers blades are become a blade group 5 with a definite quantity so that the thickness direction of vernier callipers blade is superimposed, and this quantity of determining is 10; Place two blade groups 5 on every T-shaped groove of the platform 2 of vibration ageing device, the head and the tail opposing parallel of these two blade groups 5 is arranged, and is pressed on the platform 2 with two ends and the middle part of three block pressur plates 3 with these two blade groups 5; With vibration ageing device the vernier callipers blade is fixed on new part of composition on the platform 2 like this, new member is carried out oscillating aging process, can effectively eliminate in batches the unrelieved stress of vernier callipers blade inside; Carry out the vernier callipers blade tracking detection that oscillating aging is processed to 1000 with this vernier callipers vibration ageing device, after the vernier callipers that assembles was placed for some time, the flexural deformation of length direction and the torsional deformation of width did not appear in the vernier callipers blade.
