Background technology
Two-way rack bar weight counterbalance lowering or hoisting gear is the parts on drill rod grinding machine, and at present, the feeding mode of similar lowering or hoisting gear is by automatically controlled, hydraulic pressure etc., automatically controlled needs introduces electric-control system, and hydraulic pressure needs to introduce hydraulic system, although the precision of ensure that, but insufficient sensitivity.
In view of this, the two-way rack bar weight counterbalance lowering or hoisting gear of a kind of drill rod grinding machine provided by the invention utilizes mechanical system to realize transmission and completes elevating function, the amount of feeding is regulated by two-way rack bar weight counterbalance, carrying highly sensitive simultaneously effective raising machining accuracy and grinding efficiency, simple in construction simultaneously, with low cost, adapt to severe working condition.
Summary of the invention
Solve the technical problem that
The main purpose of the present invention is to utilize mechanical system to realize transmission to complete elevating function, it is used on drill rod grinding machine, regulates the amount of feeding by two-way rack bar weight counterbalance, be effectively realized machining accuracy, increase safety loading coefficient, be beneficial to drill rod grinding machine and work under severe conditions.
Solve the technical scheme that its technical problem adopts
For solving above-mentioned technical problem, the present invention is achieved through the following technical solutions:
The two-way rack bar weight counterbalance lowering or hoisting gear of a kind of drill rod grinding machine, mainly includes weight gear case and balancing weight balance weight assembly;It is characterized in that: described weight gear case and gear-box installing plate are bolted, gear-box installing plate and frame are bolted;Weight gear case is provided with two-way tooth bar engagement transmission mechanism, supports the translational speed of tooth bar for improving to rise, and the support tooth bar that rises in two-way tooth bar engagement transmission mechanism engages with gear wheel, and the drop-down tooth bar of counterweight engages with little gear;The described upper end supporting tooth bar that rises is fixed on the lower section of main shaft installing plate by Flange joint;For alleviating the labor intensity of operator, being provided with balancing weight balance weight assembly in drop-down tooth bar lower end, described balancing weight balance weight assembly and the drop-down tooth bar of counterweight are fixed by Flange joint;Described balancing weight balance weight assembly runs in balancing weight gathering sill.
The two-way rack bar weight counterbalance lowering or hoisting gear of described drill rod grinding machine, it is characterised in that: the gear ratio of described little gear and bull wheel is 1:3.
The two-way rack bar weight counterbalance lowering or hoisting gear of described drill rod grinding machine, it is characterised in that: the perforate of flange is set to square hole.
Beneficial effect
The present invention in use, carries out counterweight according to the pressure summation that parts quality on spindle motor installing plate produces, and lowering or hoisting gear is lighter when upstream or downstream.
The two-way rack bar weight counterbalance lowering or hoisting gear of a kind of drill rod grinding machine provided by the invention, simple in construction, with low cost, regulate the amount of feeding by two-way rack bar weight counterbalance, improve sensitivity and working (machining) efficiency, add safety coefficient, adapt to severe working condition.

Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, to the two-way rack bar weight counterbalance lowering or hoisting gear detailed description of the invention of drill rod grinding machine proposed according to the present invention, structure, feature and effect thereof, describe in detail as after.
Referring to accompanying drawing, the two-way rack bar weight counterbalance lowering or hoisting gear of a kind of drill rod grinding machine, mainly include weight gear case 4 and balancing weight balance weight assembly 11;It is characterized in that: described weight gear case 4 is bolted with gear-box installing plate 7, and gear-box installing plate 7 and frame 8 are bolted;Weight gear case 4 is provided with two-way tooth bar engagement transmission mechanism, supports the translational speed of tooth bar 2 for improving to rise, and the support tooth bar 2 that rises in two-way tooth bar engagement transmission mechanism engages with gear wheel 6, and the drop-down tooth bar of counterweight 3 engages with little gear 5;The described upper end supporting tooth bar 2 that rises is fastened on the lower section of main shaft installing plate 1 by flange 10;For alleviating the labor intensity of operator, being provided with balancing weight balance weight assembly 11 in drop-down tooth bar 3 lower end, described balancing weight balance weight assembly 11 is connected fixing with the drop-down tooth bar 3 of counterweight by flange 10;Described balancing weight balance weight assembly 11 runs in balancing weight gathering sill 9;Described little gear 5 and the gear ratio of gear wheel 6 are 1:3;The perforate of flange 10 is set to square hole.
The present invention is in use, pass through joystick, realize the lifting of main shaft installing plate 1, before centering, lifting handle, engaged with little gear 5 by the support tooth bar 2 that rises and the drop-down tooth bar 3 of counterweight rises so that rising supports tooth bar 2 with engaging of gear wheel 6, main shaft installing plate 1 is driven to rise, centering body is adjusted, lower pressure hands handle, engaged with gear wheel 6 by the support tooth bar 2 that rises and the drop-down tooth bar of counterweight 3 supports the decline of tooth bar 2 with the realization rising of engaging of little gear 5, drive main shaft installing plate 1 to decline and carry out centering, centering complete after lifting handle, centering body is resetted, open reductor and bistrique, the bore bit of abrasion is carried out reconditioning by lower pressure handle.
The above, it it is only presently preferred embodiments of the present invention, not the present invention is done any pro forma restriction, any without departing from technical solution of the present invention content, according to any simple modification, equivalent variations and modification that above example is made by the technical spirit of the present invention, all still fall within the scope of technical solution of the present invention.
