Abstract
The utility model relates to a tail frame transmission mechanism for a roll grinder, which comprises a gear shaft, a motor, a gear and a rack, wherein the gear shaft is mounted on a tail frame, the motor is connected with the gear shaft and used for driving the gear shaft to rotate, the gear is arranged on the gear shaft, and the rack is transversely arranged on a machine tool body and meshed with the gear. The gear shaft is mounted on the tail frame through an eccentric bushing; a mounting hole for accommodating the eccentric bushing is formed on the tail frame; the eccentric bushing is sleeved in the mounting hole and can be loosely locked and fixed through a positioning part; eccentric holes another penetrating in the axial direction of the eccentric bushing are formed on the eccentric bushing; and the gear shaft is rotationally sleeved in the eccentric holes. The transmission mechanism can be used for conveniently adjusting the mesh clearance between the gear and the rack so as to improve the transmission precision of the tail frame.
Description
Technical field
The utility model relates to the roll grinder field, relates in particular to a kind of tailstock transmission mechanism of roll grinder.
Background technology
Roll grinder is used for the breaker roll roll surface and does periodic grinding reparation, it mainly is made up of lathe bed, the headstock, tailstock, carriage, bistrique, measurement bay and electric digital control system, the headstock is fixedly set on the lathe bed, and tailstock and carriage can move along the guide rail adjustment that is arranged on the lathe bed.The transmission mechanism of existing tailstock generally by being installed on gear shaft on the tailstock, connecting motor that gear shaft rotates, being arranged at the tooth bar that gear on the gear shaft and lateral arrangement be meshed with gear forming on lathe bed, cooperates with the driving tailstock by gear and tooth bar and moves along guide rail.In actual production process, often need manually shovel and scrape guide pass, so that tailstock and guide pass have the excellent contact face, thus the transmission accuracy of raising tailstock, but often shovel is scraped the back lash that guide pass will influence wheel and rack, finally influences the normal transmission of tailstock.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of tailstock transmission mechanism simple in structure is provided, and this mechanism can adjust the back lash of wheel and rack easily, to improve the transmission accuracy of tailstock.
The purpose of this utility model realizes by following technical solution:
The tailstock transmission mechanism of roll grinder, comprise the gear shaft that is installed on the tailstock, connect the motor that gear shaft is rotated, be arranged at the gear on the gear shaft, and the tooth bar that on lathe bed, is meshed of lateral arrangement with gear, it is characterized in that: described gear shaft is installed on the tailstock by an eccentric bushing, be formed with the installing hole that is used for ccontaining described eccentric bushing on the described tailstock, described eccentric bushing is set in the described installing hole, and releasably be locked by keeper, described eccentric bushing is formed with the eccentric orfice that axially connects along it, and described gear shaft is set in the described eccentric orfice rotationally.
Further, described eccentric bushing one end port is formed with along vertical its axial outward extending connecting ring, be formed with some bolt penetration hole on the connecting ring around its center circle distribution, be formed with some screws of aiming at one by one with bolt penetration hole on the described tailstock, described eccentric bushing releasably is locked on the tailstock by the some bolts that are arranged in bolt penetration hole and the screw.
The utlity model has following beneficial effect:
Gear shaft is installed on the tailstock by eccentric bushing, and the effect of eccentric bushing is in order the time to leave the normal engagement that enough surpluses guarantee gear and tooth bar in processing and assembling; When scraping etc. former thereby when causing the back lash of gear and tooth bar unreasonable, can realize that gear shaft adjusts in vertical direction by the rotating eccentricity cover, thereby guarantee that gear and tooth bar have suitable back lash because of guide pass is manually shoveled.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done explanation in further detail.
Fig. 1 is a structure cutaway view of the present utility model.
Fig. 2 is the structure cutaway view of the utility model eccentric bushing.
Fig. 3 is an A-A line cutaway view among Fig. 2.
The specific embodiment
With reference to Fig. 1, Fig. 2 and shown in Figure 3, the tailstock transmission mechanism of roll grinder comprises the installing hole 11 that is formed on the tailstock 1, is set in eccentric bushing 2 in the installing hole 11, is set in gear shaft 3 in the eccentric bushing 2, connects motor 7 that gear shaft 3 rotates, is arranged at the tooth bar 5 that gear 4 on the gear shaft 3 and lateral arrangement are meshed with gear 4 on lathe bed 6.
In order to guarantee the correct engagement gap of gear 4 and tooth bar 5, the gap here is usually about 0.1-0.15mm, when variation has taken place gear shaft 3 centre-heights, gear shaft 3 can be transferred to suitable position again by rotating eccentricity cover 2, and be locked by bolt 22.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
