Abstract
The utility model discloses a positioned clamping device, which belongs to the technical field of fixing components. The utility model is composed of the taper pin of an eccentric positioning shaft, an eccentric positioning sleeve, a disk-shaped spring, the seat of the positioned clamping device, a clamping screw bolt, and a press plate. The disk-shaped spring is sleeved on the taper pin of an eccentric positioning shaft, and is arranged in the eccentric positioning sleeve together. The disk-shaped spring is pressed by the press plate which is connected with the seat of the positioned clamping device through the clamping screw bolt. The positioned clamping device is installed on the left lateral plate and the right lateral plate of a screen body. The utility model has the advantages of simple structure, reliable positioning and clamping, the improvement of operational conditions, and the improvement of production efficiency. The positioned clamping device is especially suitable for vibration screening devices which are adopted in the mine industry, the metallurgy industry, the chemical industry, the building industry, etc.
Description
The utility model belongs to the fixed component technical field, particularly is applicable to a kind of positioning clamping device of the vibrosieve equipment that industry factories and miness such as mine, metallurgy, chemical industry, building are adopted.
Now be used for the vibrosieve equipment that industry factories and miness such as mine, metallurgy, chemical industry, building are adopted, various sieve plates are critical pieces of vibratory sieve, quantity is many, need to adopt a large amount of bolts and sieve nest to be bound up, because during sieve plate work, always be subjected to being sized washing away of material, quick abrasion is changed frequent; And the mesh of sieve plate is easily stopped up by material, also needs often cleaning, and the bolt of usefulness is positive fixing usually, when making installation, dismounting, cleaning, the replacing of sieve plate, the workman must climb in the crack of sieve nest and sieve plate and operate, work under bad environment, operation is extremely inconvenient, and the replacing time is long; And sieve plate interchangeability is poor, otherwise requires that the higher accuracy of manufacture is arranged, and installs accurately to guarantee it, and manufacturing cost is raise.
The purpose of this utility model is to provide a kind of simple in structure, easy installation and removal, location reliable clamping, processing technology simple, and can simplify the structure and the processing technology of sieve plate, makes sieve plate that the positioning clamping device of good interchangeability be arranged.
The purpose of this utility model realizes as follows: the locating shaft of positioning clamping device is eccentric locating shaft taper pin, and positioning sleeve is eccentric positioning sleeve; Eccentric locating shaft taper pin one end is the taper round platform, on the axle step is arranged, disk spring withstands step and is enclosed within on the eccentric locating shaft taper pin, with placing in the eccentric positioning sleeve, pressing plate is pushed down disk spring, and pressing plate is connected with the positioning clamping device seat by fishbolt, and the positioning clamping device seat is installed on the plate of the sieve nest left and right sides and combines as a whole with sieve nest, there is bellmouth the sieve plate both sides, and the active force of disk spring promotes eccentric locating shaft taper pin and heads into bellmouth and compress sieve plate.
In technique scheme, positioning clamping device is installed on the plate of the sieve nest left and right sides, the installation of sieve plate, convenient disassembly, and eccentric locating shaft taper pin is adopted in the location, rotating eccentricity locating shaft taper pin or eccentric positioning sleeve then can compensate the machining deviation of sieve plate taper hole, reach accurate centering (maximum adjustment amount for ± 2.2mm), location reliable clamping, adjusting range reduce the processing cost of sieve plate greatly, greatly, make sieve plate that good interchangeability be arranged.So economic security, laborsaving saving time, quick and convenient, alleviated labor strength, improved operating condition, improved labor productivity.
Below in conjunction with accompanying drawing concrete enforcement of the present utility model is described further.
Fig. 1 is the positioning clamping device structural representation
Fig. 2 is bar sieve plate and positioning clamping device assembling schematic diagram thereof
Among the figure, part 1 is a positioning clamping device, and part 2 is bar sieve plates, and part 3 is sieve nest backbars, part 4 is eccentric locating shaft taper pins, and part 5 is eccentric positioning sleeves, and part 6 is that disk spring, part 7 are positioning clamping device seats, part 8 is fishbolts, and part 9 is pressing plates, and part 10 is sieve nests.
Positioning clamping device 1 is by eccentric locating shaft taper pin 4, eccentric positioning sleeve 5, and disk spring 6, positioning clamping device seat 7, fishbolt 8, pressing plate 9 is formed.Eccentric locating shaft taper pin 4 one ends of positioning clamping device 1 are the taper round platform, on the axle step is arranged, disk spring 6 withstands step and is enclosed within on the eccentric locating shaft taper pin 4, with placing in the eccentric positioning sleeve 5, pressing plate 9 is pushed down disk spring 6, pressing plate 9 is connected with positioning clamping device seat 7 by fishbolt 8, positioning clamping device 1 is installed on sieve nest 10 left and right sides plates by positioning clamping device seat 7 and combines as a whole with sieve nest 10, there is bellmouth bar sieve plate 2 both sides, and the active force of disk spring 6 promotes eccentric locating shaft taper pin 4 and heads into bellmouth compression bar sieve plate 2.Install when adjusting, unclamp the nut of the fishbolt 8 of positioning clamping device 1 in sieve nest 10 sides, rotating eccentricity locating shaft taper pin 4 or eccentric positioning sleeve 5, also simultaneously rotating eccentricity locating shaft taper pin 4 and eccentric positioning sleeve 5, then can compensate the machining deviation of bar sieve plate 2 taper holes, reach accurate centering.Disk spring 6 can make eccentric locating shaft taper pin 4 compensate clamping automatically after the 2 both sides bellmouth wearing and tearing of bar sieve plate and can not become flexible.Adopt this clamping device can simplify the structure of bar sieve plate 2, at this moment bar sieve plate 2 can become with the grating assembly welding with two backbars.
Sieve plate is the bar sieve plate in the present embodiment, and sieve plate can be the mesh sieve plate in actual the use, or other forms of sieve plate.
