Abstract
The utility model relates to a back rack adjusting device which comprises a screw rod, wherein a vertical spring rack is inserted on the screw rod; two spring guide bars with the same distance with the screw rod are arranged on the two sides of the spring rack respectively; springs are sleeved with the position between spring supports of the spring guide bars and the spring rack respectively; two bolted screw nuts are arranged on the position, in the range of the spring rack, of the screw rod; gaskets are arranged at the back end of the second boltedscrew nut; and a disc spring is arranged between the gaskets and the spring rack. Through the adoption of the structure that large spring compression amount of the screw rod is shared by the springs on the spring guide bars; and the springs can do relative movement with the spring guide bars by adopting the sleeved manner, the device has the advantages that the compressing force is reduced; the durability of the device is increased; and the adjusting ability is greatly enhanced by adopting the disc spring and the springs together; and the device has the characteristics that the durability is strong; the structure is novel and simple; and the operation and the maintenance are convenient.
Description
Technical field
The utility model belongs to the engineering mechanical device technical field, relates to a kind of counterattack frame adjusting device of sand machine processed.
Background technology
Traditional counterattack frame governor motion is fixed, spring frame relatively carries out relative motion, because sand machine bar quick abrasion processed and big requires counterattack frame aperture regulated quantity big as far as possible, initial amount of spring compression is excessive, compression stress is too big, damage easily and regulate part, when very big to the bar wearing and tearing, spring pressure is little, spring even fall short of can't intermittently be regulated.
The utility model content
In order to overcome the above-mentioned shortcoming of prior art
,The utility model provide a kind of spring relatively frame carry out relative motion, counterattack frame aperture regulated quantity is big, initial spring is less, thereby compression stress is the less loss that reduces or reduce the adjusting part also, has the counterattack frame adjusting device that durability is strong, novel structure simple, operating maintenance makes things convenient for characteristics.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of counterattack frame adjusting device, comprise screw rod, assign a spring(-supported) mount of establishing at screw rod, be respectively equipped with two and the equidistant spring guide of screw rod in the both sides of spring(-supported) mount, be socketed with spring at the spring fastening of spring guide and the position between the spring(-supported) mount, position in screw rod places the spring(-supported) mount scope is provided with two bolt nuts, rear end at second bolt nut is provided with packing ring, is provided with the dish spring between packing ring and the spring(-supported) mount.
The front end of described screw rod is provided with the screw rod cover, and the rear end of screw rod is fixed on the frame of counterattack frame.
Front end at described spring guide is provided with the studs swivel nut.
Described studs swivel nut rear end is provided with nut structure, and nut structure interfixes by plain washer and spring fastening.
The beneficial effects of the utility model are: the bigger amount of spring compression of having shared screw rod by the spring on the spring guide, adopt the mode of socket to make simultaneously and can carry out relative motion between spring and the spring guide, reduced compression stress, increased the durability of device, adopt dish spring and spring to regulate jointly and strengthened regulating power greatly, have that durability is strong, novel structure simple, operating maintenance characteristics easily.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1-screw rod, 2-screw rod cover, 3-spring guide, 4-spring fastening, 5-studs swivel nut, 6-nut structure, 7-plain washer, 8-spring, 9-spring(-supported) mount, 10-bolt nut, 11-packing ring, 12-dish spring, 13-frame.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1, a kind of counterattack frame adjusting device, comprise screw rod 1, the front end of screw rod 1 is provided with screw rod cover 2, the rear end of screw rod 1 is fixed on the frame 13 of counterattack frame, assign a spring(-supported) mount of establishing 9 at screw rod 1, be respectively equipped with two and screw rod 1 equidistant spring guide 3 in the both sides of spring(-supported) mount 9, front end at spring guide 3 is provided with studs swivel nut 5, studs swivel nut 5 rear ends are provided with nut structure 6, nut structure 6 interfixes by plain washer 7 and spring fastening 4, be socketed with spring 8 at the spring fastening 4 of spring guide 3 and the position between the spring(-supported) mount 9, position in screw rod 1 places spring(-supported) mount 9 scopes is provided with two bolt nuts 10, is provided with packing ring 11 in the rear end of second bolt nut 10, is provided with dish spring 12 between packing ring 11 and the spring(-supported) mount 9.
The utility model has been shared the bigger amount of spring compression of screw rod by the spring on the spring guide, adopt the mode of socket to make simultaneously and can carry out relative motion between spring and the spring guide, reduced compression stress, increased the durability of device, adopt dish spring and spring to regulate jointly and strengthened regulating power greatly, have that durability is strong, novel structure simple, operating maintenance characteristics easily.
