Embodiment 1

[0042] Embodiment 1: as figure 2 and image 3 As shown, an expansion positioning detection tool for the verticality detection of casing products, which includes an outer sleeve 3 with a detection reference plane B and a conical expansion pin 4 arranged inside the outer sleeve 3, the conical expansion pin 4 can move back and forth inside the outer sleeve 3 along the axial direction of the outer sleeve 3, the central axis of the outer sleeve 3 coincides with the central axis of the tapered expansion pin 4, and there are holes on the peripheral surface of the outer sleeve 3 A plurality of through slots, each of which is provided with a movable wedge 5; during detection, after the outer sleeve 3 is inserted into the casing product 1, the tapered expansion pin 4 is pushed out along the axial direction of the outer sleeve 3. The inner movement of the sleeve uses the cooperation of the tapered expansion pin 4 and the movable wedge 5 to drive the movable wedge 5 to move and protrude...

Embodiment 2

[0054] Embodiment 2: as Figure 9 and Figure 10 As shown, the plurality of through grooves 6 of the outer sleeve 3 are all tapered through grooves, and the movable wedge is trapezoidal, and the upper bottom edge 511 and the lower bottom edge 412 of the trapezoidal movable wedge are hypotenuses, and the ladder One side waist of the shape movable wedge is a straight edge, and the other side waist of the trapezoidal movable wedge is a hypotenuse; Utilize the tapered through groove 6 and the inclined upper base and the inclined lower bottom of the trapezoidal movable wedge 5 Edge fit, so that multiple trapezoidal movable wedges 5 are limited in multiple tapered through grooves 6 on the outer sleeve; when testing, use the inclined waist of the trapezoidal movable wedge and the cone of the tapered expansion pin The surface is in contact with each other, and the straight waist of the trapezoidal movable wedge is in contact with the inner peripheral surface of the casing product. I...

Abstract

The invention discloses a swelling positioning detection tool for detecting the perpendicularity of a casing pipe type product and a detection method. The swelling positioning detection tool comprisesan outer sleeve and a cone-shaped swelling pin, wherein the outer sleeve is provided with a detection reference plane, the cone-shaped swelling pin can move back and forth in the outer sleeve along the axial direction of the outer sleeve, a central axis of the outer sleeve is coincided with of a central axis of the cone-shaped swelling pin, a plurality of through slots are formed in the circumferential surface of the outer sleeve, and a movable wedge-shaped block is arranged in each through slot. In a detection process, the outer sleeve is inserted into the casing pipe type product, the cone-shaped swelling pin moves in the outer sleeve along the axial direction of the outer sleeve and is matched with the movable wedge-shaped blocks to drive the wedge-shaped blocks to move and stretch outalong the radial direction of the outer sleeve, multiple wedge-shaped blocks are in contact with inner circumferential surface of the casing pipe type product, the gap distance from the detection reference surface of the outer sleeve to the detection reference surface of the casing pipe type product is detected, and then the perpendicularity of the casing pipe type product can be detected. According to the detection tool, the accuracy of the detection result can be guaranteed.

Description

technical field [0001] The invention relates to a verticality detection tool and a detection method for casing products, in particular to an expansion positioning detection tool and a detection method for the verticality detection of casing products. Background technique [0002] At present, there are more than a dozen types of subway fastener systems at home and abroad. The non-metal parts of the fasteners in the entire fastener system mainly play the role of insulation, vibration reduction, gauge adjustment and height adjustment. The fastener system mainly includes insulating gauge blocks, under-rail / under-slab elastic backing plates, embedded bushings, height-adjusting backing plates, etc. [0003] Pre-embedded casing products mainly play the role of fixing the iron backing plate in the entire fastener system. As an important part of the fastener system, they are usually pre-embedded in sleepers or track slabs during their use. The embedding accuracy needs to meet the re...
