Description

Cylinder jacket locating seat that detects a flaw Technical Field The utility model belongs to the technical field of cylinder liner detection equipment, and particularly relates to a cylinder liner flaw detection positioning seat. Background After the cylinder liner is produced, flaw detection operation is required to be carried out on the surface of the cylinder liner, and flaw detection is generally carried out by adopting a flaw detector. In the prior art, when the cylinder sleeve is subjected to flaw detection, the used flaw detection positioning seats are all of a mouth shape, namely can only be suitable for a fixed product, and when a new product developed or the cylinder sleeve with a special process (Teflon coating) or different sizes is subjected to flaw detection, various flaw detection positioning seats are required to be configured, so that the waste of resources and the increase of cost are caused. Therefore, a cylinder liner flaw detection positioning seat is needed to solve the above technical problems. Disclosure of utility model In order to overcome the defects in the prior art, the utility model provides a cylinder sleeve flaw detection positioning seat, which comprises a positioning disc matched with a rotating platform of a flaw detector, wherein the positioning disc is detachably connected with the rotating platform; The positioning disc is provided with a plurality of concentric grooves, the circle centers of the concentric grooves coincide with the circle centers of the positioning disc, a plurality of grooves are uniformly distributed on the positioning disc along the circumferential direction, the grooves are arranged along the radial direction of the positioning disc, and positioning pieces are arranged in the grooves. The concentric grooves can play a reference role when the cylinder sleeves with different sizes are placed on the positioning disc, and can play an anti-skid role on the cylinder sleeves, so that the stability of the cylinder sleeves on the positioning disc is improved. Preferably, the groove is an inverted T-shaped groove, the positioning piece comprises a T-shaped bolt and a positioning block, the T-shaped bolt is arranged in the T-shaped groove in a sliding mode, and a stud of the T-shaped bolt vertically extends out of the T-shaped groove upwards and is in threaded connection with the positioning block. The positioning device has the advantages that the positioning of the cylinder sleeve can be realized by sliding the T-shaped bolts in the T-shaped grooves and the cylinder sleeve which is arbitrarily placed on the positioning disc, when the positioning device is positioned, after each positioning block is moved to be close to the cylinder sleeve, the positioning block is screwed down, and in actual use, a certain gap is reserved between the positioning block and the outer circle of the diameter of the large table of the cylinder sleeve, so that the batch flaw detection is convenient. Preferably, the positioning block is a nylon cylinder, and a screw hole matched with the T-shaped bolt is formed in the center of the positioning block. The locating block is made of nylon, so that the risk of damaging the locating block in the flaw detection process is avoided. Preferably, scale marks are arranged on the positioning plate corresponding to one side of the groove. The cylinder liner positioning device has the advantages that the positions of the movement of the positioning blocks can be accurately known through the arrangement of the scale marks, so that the positioning of the positioning blocks is more accurate, and meanwhile, the positioning of the cylinder liner can be ensured to be accurate by taking the positioning blocks as references. Preferably, a plurality of mounting holes are uniformly formed in the positioning disc along the circumferential direction, mounting bolts are matched with the mounting holes, and the positioning disc is detachably connected with the rotating platform through the mounting bolts. The working principle is that the positioning disc is fixed on a rotating platform of the flaw detector through the mounting bolts when the flaw detector is in use, then the cylinder sleeve is placed on the positioning disc opposite to the concentric grooves, finally each positioning block and the T-shaped bolts slide towards the cylinder sleeve, finally the positioning block is screwed down, and the positioning block is fixed on the positioning disc, so that a certain gap exists between the positioning block and the outer circle of the diameter of the large table of the cylinder sleeve, and the flaw detector is convenient to use in batch flaw detection. The utility model also comprises other components which can enable the cylinder sleeve flaw detection positioning seat to be used normally, and the other components are all conventional technical means in the field. In addition, the devices or components, such as those not defined in the present utility m
