Abstract
The utility model belongs to the field of metering spacing or a gap of separated objects, and more specifically to a gap detection apparatus of a valve stem and a conduit. The gap detection apparatus comprises a dial indicator. The gap detection apparatus is also provided with a motor base, clamping blocks, a support and cylinders arranged on the motor base in pairs. EacEach clamping block is arranged on a piston rod of one cylinder. Two clamping blocks are opposite and used for clamping the conduit in a matching way. The lower end of each clamping block is slidably connected with the motor base. A location hole s arranged on the motor base between the two clamping blocks. The support is fixedly arranged on the motor base. The dial indicator is connected with the support, and a measuring head of the dial indicator is abutted with an edge of a valve collar. According to the gap detection apparatus of the valve stem and the conduit, the valve stem and a valve which are not assembled in a cylinder cover are fixed, and the gap of the valve stem and the valve are detected.
Description
Technical field
The utility model belongs to for measuring spacing or the field, gap in spaced object or hole, is specifically related to a kind of valve stem and conduit gap detection device.
Background technology
Valve stem and conduit tolerance clearance are generally 0.02mm～0.1mm, and during excesssive gap, cylinder upper part of the cover machine oil enters air flue and sucks cylinder between valve guide bushing and valve stem; When gap is too small, valve stem expanded by heating, easily blocks valve stem, and valve motion is malfunctioning.
Valve stem and the conduit being assemblied in cylinder normally detected in existing detection valve stem and conduit gap, and the position of conduit is fixed, if in the time of will detecting the gap of unassembled valve stem to cylinder and conduit, conduit exists problem that cannot be fixing.
Utility model content
The defect existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of energy to fix unassembled valve stem and valve to cylinder cap, and detects valve stem and the conduit gap detection device in valve stem and conduit gap,
For achieving the above object, the technical solution of the utility model is: valve stem and conduit gap detection device, comprise dial gauge, wherein, also be provided with support, grip block, support and be arranged in pairs the cylinder on support, on the piston rod of cylinder, be equipped with grip block, two grip blocks relatively also coordinate clamping conduit, and grip block lower end and support are slidably connected; Pedestal between two grip blocks is provided with pilot hole; Described support is fixed on support, and described dial gauge is connected with support, and the measuring head of dial gauge and Valve Disc edge offset.
While adopting technique scheme, valve stem is inserted after conduit, valve stem lower end is stretched in pilot hole, control two cylinders, the piston rod of two cylinders is stretched out, on piston rod due to two cylinders, be equipped with grip block, two grip blocks relatively move and conduit are clamped, then will on valve, carry to the dish portion edge of valve and the contour position of the measuring head of dial gauge, calibration dial gauge, then valve stem is pulled in left and right, observe the reading variation range of dial gauge, if reading variation range is in 0.02mm～0.1mm, the gap of valve stem and conduit in allowed limits.The cylinder that the utility model is oppositely arranged, and the grip block being arranged on cylinder piston rod can fix unassembled conduit to cylinder cap, is convenient to detect the gap between valve stem and conduit.
Further, described dial gauge is provided with the expansion link being slidably connected with support, the valve of different size, and the size of dish portion is also inconsistent, and dial gauge is slidably connected by expansion link and support, and the measuring head of dial gauge just can coordinate the dish portion edge of sizes valve stem.
Further, described support lower end is provided with lifting table, and described support is threaded with lifting table, and the so just lifting of energy adjusting pole, to coordinate the height of Valve Disc.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model valve stem and conduit gap detection device embodiment.
Embodiment
As shown in Figure 1, a kind of valve stem and conduit gap detection device, comprise dial gauge 4, wherein, be also provided with support 1, grip block 7, support 3 and be arranged in pairs the cylinder 8 on support 1, grip block 7 clamping one sides have the clamping face of V-arrangement, on the piston rod 81 of cylinder 8, be equipped with 7, two grip blocks of grip block 7 and relatively also coordinate clamping conduit 6, grip block 7 lower ends and support 1 are slidably connected, wherein grip block 7 lower ends are provided with movable pulley, and support 1 is provided with the chute 9 coordinating with movable pulley; Pedestal between two grip blocks 7 is provided with pilot hole 10, and pilot hole 10 is positioned at the centre position of two grip blocks 7; Support 3 is fixed on support 1, and dial gauge 4 is connected with support 3, and the measuring head 41 of dial gauge 4 offsets with Valve Disc edge.
In the present embodiment, dial gauge 4 is provided with the expansion link 2 being slidably connected with support 3, the valve 5 of different size, and the size of dish portion is also inconsistent, dial gauge 4 is slidably connected by expansion link 2 and support 3, and the measuring head 41 of dial gauge 4 just can coordinate the dish portion edge of sizes valve stem.
Support 3 lower ends are provided with lifting table, and support 3 is threaded with lifting table, and the so just lifting of energy adjusting pole 3, to coordinate the height of Valve Disc.
The concrete flow process of using:
As shown in Figure 1, valve stem is inserted after conduit 6, valve stem lower end is stretched in pilot hole 10, control two cylinder 8 air inlets, the piston rod 81 of two cylinders 8 is stretched out, on piston rod 81 due to two cylinders 8, be equipped with grip block 7, and grip block 7 clamping one sides have the clamping face of V-arrangement, two grip blocks 7 relatively move, the clamping face of two grip blocks 7 is by conduit 6 clampings, conduit 6 is relatively fixing, then will on valve 5, carry to the dish portion edge of valve 5 and the contour position of the measuring head 41 of dial gauge 4, calibration dial gauge 4, then valve stem is pulled in left and right, observe the reading variation range of dial gauge 4, if reading variation range is in 0.02mm～0.1mm, the gap of valve stem and conduit 6 in allowed limits, if reading variation range is exceeding 0.02mm～0.1mm scope, the gap of valve stem and conduit 6 is defective.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
