Abstract
The utility model relates to a ram unloading device. The current ram of main solution needs three linear guide when feeding and has increased the problem of the processing degree of difficulty and cost. Its characterized in that: be connected with on ram (1) bottom surface thread bush (10), and thread bush (10) bottom is fixed on ram (1) through flange dish (7), thread bush (10) inside hypomere has been put the gyro wheel and has been supported cover (6), the gyro wheel supports cover (6) bottom and is connected with gyro wheel (4), adjusting bolt (11) have been put to thread bush (10) inside upper segment, and adjusting bolt (11) lower extreme optical axis section is arranged the gyro wheel in and is supported cover (6) inside, and outer deployment of optical axis section has dish spring (8), optical axis section upper portion is equipped with the boss. This ram unloading device is adopted, linear guide of cancellation can be reduced to reduce two side guide's atress, reduce the processing degree of difficulty and cost.
Description
Technical field
The utility model relates to mechanical field, specifically a kind of ram relief arrangement.
Background technology
During current ram feeding guide rail employing line slideway, be three guide rail layouts, ram 3 is fixed with three line slideways, line slideway block is fixed on main spindle box, and during ram feeding, ram drives line slideway to move in line slideway block.The ram of this structure needs the locating slot of processing three line slideways, increase difficulty of processing and machine add cost, and need select three line slideways, increase purchase cost.
Summary of the invention
In order to the deficiency needing three line slideways to add difficulty of processing and cost when overcoming existing ram feeding, the utility model provides a kind of ram relief arrangement, adopt this ram relief arrangement, can reduce and cancel straight line guide rail, and reduce the stressed of two sides guide rail, reduce difficulty of processing and cost.
The technical solution of the utility model is: a kind of ram relief arrangement, comprise ram, bottom surface is connected with thread bush to ram, and being fixed on ram by ring flange bottom thread bush, the inner hypomere of thread bush is equipped with roller supporting cover, and roller supporting cover bottom is connected with roller, the inner epimere of thread bush is equipped with adjustment bolt, and adjustment bolt lower end optical axis section is placed in roller supporting cover inside, and optical axis section outside is equipped with disc spring, and optical axis section top is provided with boss.
Described thread bush top has oil duct, and the sidewall on oil duct top is fixed with lubricating cup.
Described roller supporting cover is connected by key with between thread bush.
The utility model has following beneficial effect: owing to taking such scheme, this relief arrangement instead of line slideway bottom ram, and when ram moves, roller rolls on bed piece, 80% of ram weight can be laid down, substantially reduce the stressed of two line slideways in side.And owing to eliminating a line slideway, reduce difficulty of processing and cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged drawing of relief arrangement in Fig. 1.
1-ram in figure, 2-line slideway, 3-relief arrangement, 4-roller, 5-key, 6-roller supporting cover, 7-ring flange, 8-disc spring, 9-lubricating cup, 10-thread bush, 11-adjusts bolt.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1, Fig. 2, a kind of ram relief arrangement, comprises ram 1, and ram 1 side is connected with two line slideways 2, connects relief arrangement 3 bottom ram 1.Described relief arrangement 3 comprises thread bush 10, and thread bush 10 has been threaded connection on ram 1 bottom surface, and is fixed on ram 1 by ring flange 7 bottom thread bush 10.Thread bush 10 inside is cascaded surface, and its hypomere is built-in with roller supporting cover 6, and roller supporting cover 6 is connected by key 5 with between thread bush 10, prevents roller supporting from overlapping 6 and rotates.Be connected with roller 4 by rotating shaft bottom roller supporting cover 6, make roller 4 free to rotate, and roller 4 rotating direction be consistent with line slideway 2 length direction.The inner epimere of thread bush 10 is equipped with adjustment bolt 11, and one section of optical axis is arranged at described adjustment bolt 11 bottom, and optical axis top is provided with boss, and boss top is the threaded portion of bolt, and adjustment bolt 11 is connected with thread bush 10 by threaded portion.It is inner that adjustment bolt 11 lower end optical axis section is placed in roller supporting cover 6, and optical axis section outside is equipped with disc spring 8, and disc spring 8 bottom withstands on roller supporting cover 6, and epimere withstands on the boss on optical axis section top.Rotate the pressure that adjustment bolt 11 can regulate disc spring 8, thus the high and low position of adjustment roller 4.Described thread bush 10 top has oil duct, and the sidewall on oil duct top is fixed with lubricating cup 9, fills lubricating grease by lubricating cup 9 in relief arrangement 3, prevents disc spring 8 from vibrating in motion process.
This relief arrangement replaces line slideway and is arranged on below ram, and when ram 1 moves, roller 4 rolls along bed piece, can lay down about 80% of ram weight, substantially reduce the stressed of two line slideways in side.And owing to eliminating a line slideway, reduce difficulty of processing and cost.
Claims (3)
1. a ram relief arrangement, comprise ram (1), it is characterized in that: ram (1) bottom surface is connected with thread bush (10), and thread bush (10) bottom is fixed on ram (1) by ring flange (7), thread bush (10) inner hypomere is equipped with roller supporting cover (6), roller supporting cover (6) bottom is connected with roller (4), thread bush (10) inner epimere is equipped with adjustment bolt (11), and adjustment bolt (11) lower end optical axis section is placed in roller supporting cover (6) inside, and optical axis section outside is equipped with disc spring (8), optical axis section top is provided with boss.
