Description

Quick erection equipment of air compressor machine impeller

Technical Field

The invention belongs to the technical field of air compressor products, and particularly relates to equipment for quickly mounting an air compressor impeller.

Background

The impeller is an important component of the air compressor, and the performance of the impeller directly influences the service condition and the service life of the air compressor. The front end of the impeller is provided with a mounting chamber, a socket is arranged in the mounting chamber, and the motor rotor is inserted into the socket to be fixedly connected with the impeller. The side wall of the socket is provided with a plurality of notches, so that the motor rotor can conveniently enter the socket. The high temperature of air compressor machine operation and the natural aging of material, the clamping force of socket reduces, appears skidding or the phenomenon that breaks away from each other between impeller and the electric motor rotor, in order to solve this problem, I department with the spring card in the impeller, the spring can play the effect of tightening up, the difficult not hard up of machine operation in-process impeller and drop.

The spring card tightens up the socket in the impeller, and is difficult to press the impeller on electric motor rotor by hand, need just can realize with the help of external force, consequently need to design the equipment of an installation impeller urgent.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: how to achieve a fast and efficient mounting of the impeller.

In order to achieve the purpose, the technical scheme provided by the invention is as follows:

the air compressor impeller rapid installation equipment comprises a bottom plate, a side baffle part, a support pillar and a base, wherein the side baffle part, the support pillar and the base are fixed in a top plate; the base is provided with a transverse through groove, a rack is installed in the transverse through groove, a gear meshed with the rack is arranged in the base, a driving piece for driving the gear to rotate is arranged at the top of the base, a push rod is installed on one side, corresponding to the support column, of the rack, and a positioning portion is arranged at the free end of the push rod.

Compared with the prior art, the invention has the beneficial effects that: the gear and the rack form a gear rack mechanism, external force is transmitted to the impeller through the gear and the rack, and the impeller is quickly and effectively installed instead of being manually installed.

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly introduced below.

FIG. 1 is a partial exploded view of a pump head in an embodiment;

FIG. 2 is a structural view of a mounting apparatus in the embodiment;

fig. 3 is a sectional view of the push rod in the embodiment.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to the motor rotor 10 and the impeller 20 shown in fig. 1, the spring 30 is first sleeved outside the socket of the impeller, and then the impeller is press-fitted on the motor rotor. The mounting device shown in fig. 2 is used for press-mounting the impeller on the motor rotor, and comprises a bottom plate 40, a side baffle 50 fixed in the top plate, a support column 60 and a base 70, wherein a support base 60 is mounted between the side baffle and the base, a positioning boss 61 is arranged at the top of the support base, a hole position at the bottom of the pump head just corresponds to the positioning boss, and the pump head is placed on the support base, so that positioning can be realized, and the pump head can be prevented from moving under external force. The base is provided with a transverse through groove, a rack 80 is arranged in the transverse through groove, a gear (not shown in the figure) meshed with the rack is arranged in the base, the top of the base is provided with a driving piece for driving the gear to rotate, one side of the rack corresponding to the supporting column is provided with a push rod 110, and the free end of the push rod is provided with a positioning part. The gear and the rack form a gear rack mechanism, external force is transmitted to the impeller through the gear and the rack, and the impeller is quickly and effectively installed instead of being manually installed.

Wherein, the driving piece can adopt the handle, and the assembly personnel manually rotate handle 90, through the feedback manual regulation installation dynamics of power. The driving piece can also adopt a servo speed reduction motor, and the automatic assembly of the impeller is realized in an electric mode.

The bottom plate 40 is provided with a sliding groove 41, the bottom of the push rod is provided with a sliding rod 100 extending into the sliding groove, and one end of the sliding groove corresponding to the supporting column is provided with a pressure sensor. The position of the sliding rod in the sliding groove can indirectly reflect the displacement distance of the push rod, and when the pressure value of the pressure sensor reaches a preset value, the servo speed reduction motor stops rotating. An alarm indicator light is arranged on the bottom plate, and when the indicator light is on, an assembler stops rotating the handle.

Referring to fig. 3, a movable inner push rod 120 is provided in the push rod 110; one end of the inner ejector rod positioned in the push rod is connected with the push rod by a spring part 130; in an uncompressed state of the spring element, the inner knock rod extends to an outside of the positioning portion. After the impeller is assembled, the push rod retreats, the inner ejector rod always presses the impeller under the action of the spring part, and the impeller is effectively prevented from being pulled backwards by the push rod.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles described herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
