Abstract
The utility model discloses an eccentric block structure of a combined vibration exciter, wherein an eccentric block is divided into a main eccentric block and an auxiliary eccentric block along the radial direction of the eccentric block, and bolt connecting holes are correspondingly formed in the main eccentric block and the auxiliary eccentric block and are connected through bolts. The utility model greatly simplifies the processing procedure of the main eccentric block and improves the production efficiency by adopting the combined eccentric block structure.
Description
Technical Field
The utility model belongs to the field of vibration exciters, and particularly relates to an eccentric block structure of a combined vibration exciter.
Background
The vibrating screen is a material grading device indispensable in various industries such as metallurgy, coal, mine, sandstone and the like, and drives a vibrating screen box to vibrate on a set track by generating centrifugal force through high-speed rotation of an eccentric block on a vibration exciter. The excitation force generated by the vibration exciter cannot be separated from the eccentric block, and the performance of the sieving machine is determined by the size and the balance of the eccentric block generating the eccentric static moment.
At present, eccentric blocks of vibration exciters are designed in an integrated mode, casting, forging or whole plate blanking forming is adopted, and then finish machining is carried out on the shapes, so that on one hand, the finish machining process is complicated, and the cost is high; on the other hand, the running performance of the screening machine is affected by the inconsistent weight of the eccentric blocks due to the fact that the eccentric blocks cannot be completely processed in the irregular processing process.
Disclosure of Invention
The utility model aims to provide a combined type vibration exciter eccentric block structure, which divides a main eccentric into a plurality of parts through splitting, is easy to process each part, controls the size and the precision of each part, and can be combined into more different eccentric static moment configurations to meet the use requirements of different sieving machines.
In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides a modular vibration exciter eccentric block structure, eccentric block is along its radial square subdivision into main eccentric block and vice eccentric block, has seted up bolted connection hole on main eccentric block and the vice eccentric block correspondingly to through bolted connection.
Furthermore, the bolt connecting holes are divided into two groups, and the two groups of bolt connecting holes are arranged on the lower part of the eccentric block in parallel.
Further, eccentric melon and counterweight plate are provided with respectively to the eccentric block both sides, and eccentric melon passes main eccentric block and vice eccentric block in proper order through bolt cooperation bolt connection hole and connects fixedly, and counterweight plate passes in proper order through bolt cooperation bolt connection hole and vice eccentric block and main eccentric block connects fixedly.
Further, eccentric melon and the cooperation of weight plate set up to fan-shaped, and the weight plate can be a plurality of.
Compared with the prior art, the utility model has the following beneficial effects: through the combined eccentric block structure, the processing procedure of the main eccentric block is greatly simplified, and the production efficiency is improved; the controllability of the eccentric static moment generated by the simplified eccentric block is better, the deflection caused by the inconsistent eccentric force on the two sides of the screening machine can be avoided, and the quality of the screening machine is improved; and thirdly, the combined eccentric block structure can have more eccentric configuration modes, richer eccentric static moment parameter combinations are realized, and the vibration requirements of more screening machines are met.

Detailed Description
Referring to fig. 1-2, an eccentric block structure of a combined vibration exciter is characterized in that an eccentric block 6 is divided into a main eccentric block 1 and an auxiliary eccentric block 2 along the radial direction of the eccentric block, and the main eccentric block 1 and the auxiliary eccentric block 2 are correspondingly provided with bolt 5 connecting holes and connected through bolts 5. Through with eccentric block 6 along its radial square cutting into main eccentric block 1 and vice eccentric block 2, adopt combination formula eccentric block 6 structure, simplify the manufacturing procedure of main eccentric block 1 greatly, provide its production efficiency, and in the course of the work, the controllability is higher. Eccentric block 6 is along its radial square cutting into main eccentric block 1 and vice eccentric block 2, and vice eccentric block 2 closes soon on main eccentric block 1 through bolt 5, and based on above-mentioned thinking, its vice eccentric block 2 can set up to a plurality ofly, through the quantity of the vice eccentric block 2 of increase and decrease to can adjust exciting force.
Wherein, the bolt 5 connecting holes are two groups, and the two groups of bolt 5 connecting holes are arranged at the lower part of the eccentric block 6 in parallel. The bolt 5 connecting hole can provide a fixed screwing channel of the bolt 5 for the main eccentric block 1 and the auxiliary eccentric block 2, and can also facilitate screwing of the eccentric block 3 and the counterweight plate 4 on the eccentric block 6 through the bolt 5.
Wherein, 6 both sides of eccentric block are provided with eccentric melon 3 and counterweight plate 4 respectively, and eccentric melon 3 passes main eccentric block 1 and vice eccentric block 2 through 5 connecting holes of 5 cooperation bolts of bolt and connects fixedly in proper order, and counterweight plate 4 passes in proper order through 5 connecting holes of 5 cooperation bolts of bolt and is connected fixedly with vice eccentric block 2 and main eccentric block 1. The controllability of the eccentric static moment generated by the eccentric block 6 can be effectively ensured to be better, the deflection generated by the inconsistent eccentric force on the two sides of the screening machine can be avoided, and the quality of the screening machine is improved.
Wherein, eccentric melon 3 sets up to fan-shaped with the cooperation of weight plate 4, and weight plate 4 can be a plurality of. The counterweight plate 4 can be adjusted, so that the utility model can have more eccentric configuration modes, realize richer eccentric static moment parameter combinations and meet the vibration requirements of more screening machines.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
