Description

A kind of electronic exempting from tears shock absorber compressor reducer open

Technical field

The utility model belongs to automotive engineering field of tool, and more particularly, it relates to a kind of electronic exempting from and tears shock absorber compressor reducer open.

Background technology

Existing automobile maintenance industry, when keeping in repair the suspension fork mechanism of various vehicle, particularly the disassembling operations of shock-proof spring is more frequent, traditional dismantling device one adopts lever revolution compression shock-proof spring, and this instrument takes up room comparatively large, and spring stress is uneven, poor stability, poor stability; Another kind of two rotary screws adopted with left and right screw thread, by both sides claw alternate compression shock-proof spring, this equipment volume is little, low cost of manufacture, but operation is not too convenient.In addition existing shock-proof spring compressor reducer also also exists: cost is high, poor universality, and the scope of application is little, complicated operation, the problems such as inefficiency.

On market modal structure be also structure disclosed in above-mentioned utility model as shown in Figure 1 to Figure 3, in order to realize sliding seat can under the drive of leading screw upper and lower slippage to provide the compression stress of spring, sliding seat realizes clamping by the sliding sleeve that can coordinate with leading screw, sliding sleeve arranges the upper and lower clamping of groove that two clamping blocks and sliding seat are preset, in order to the normal rotation of the slippage up and down and leading screw that ensure sleeve, so larger cavity is left in column support body inside, cavity is in communication with the outside by a chute, sliding seat is then set in column support body outer surface, two clamping blocks extend to sliding seat by chute and realize the clamping relation with it.Due to shock absorber spring maximum flexibility Li Keda more than 800 tons, so the thread turns that this leading screw is generally arranged is more, so by spring-compressed certain distance, need the number of turns that rotational lead screw is more, loaded down with trivial details in the extreme.

Disclosing application number is in the market 201320180682.X avoid-dismantle shock-proof spring compressor reducer, comprise column support body, the upper and lower two ends of column support body are provided with sliding seat and holder relatively, sliding seat is connected with the driving mechanism that sliding seat can be driven axially to move back and forth up and down on column support body, sliding seat is provided with downward opening first draw-in groove, holder is provided with the second opening up draw-in groove, and on the first draw-in groove and the second draw-in groove, the monomer be respectively equipped with for holddown spring is pitched.Driving mechanism comprises in the sliding seat described in screw mandrel be located in column support body and is provided with the internal thread that can match with screw mandrel, although it has arrange assister bar in leading screw upper end, is undertaken rotating very loaded down with trivial details trouble by manpower.

Utility model content

What exist for prior art rotates comparatively loaded down with trivial details deficiency by manpower, provides a kind of electronic shock absorber compressor reducer not needing artificial rotation.

For achieving the above object, the utility model provides a kind of electronic exempting from of following technical scheme and tears shock absorber compressor reducer open, comprise column support body, sliding seat, holder and the leading screw be located in described column support body, described sliding seat is provided with the sliding sleeve that can coordinate with leading screw, sliding sleeve be provided with two for the upper clamping block of sliding seat clamping and lower clamping block, described column support body offers chute, the top of described column support body is fixed with motor, the rotating shaft of described motor and described leading screw circumference link and arrange, described motor is connected with motor drive plate, described motor drive plate is connected with start stop switch, described motor drive plate passes through powered battery.

Rotate to compare by driven by motor rotating shaft and directly rotated by manpower, not only increase the efficiency of a job, and comparatively safe, and compression is very laborsaving, transmission is also relatively stable, and user just can control the position of sliding sleeve by start-stop button, simple and reasonable.Motor drive plate can select modal motor drive plate MCT700, AQMD2410NS, ULN2003 etc. all to disclose motor drive mode, only to be connected with motor drive terminal with the terminals preset and just can to realize driving, and all disclose start stop switch, the rotating forward of motor, reversion and stall just can be realized by controlling start stop switch.

The utility model can be set to further: described motor drive plate is also connected with speed-regulating potentiometer.

By arranging speed-regulating potentiometer, user situation as required can select the rotating speed of motor, because motor speed can not be excessive, particularly direct current generator, the rotating torque drive screw turns that one stable can not be provided when rotating speed is too large, so generally motor speed torque=9550* power/rotating speed, so in the process more and more compressed at spring, along with the compression stress of spring increases, the moment of its load also can increase relatively, if so now rotating speed is too large, need to reduce the demand that motor speed can meet torque, by arranging speed-regulating potentiometer, rotating speed is less at the beginning, then slowly rotating speed is increased, when compressing the spring into the position close to needing, again rotating speed is reduced, carry out vernier control.

The utility model can be set to further: 12V stepper motor elected as by described motor.

Because motor of the present utility model is less to speed demand, higher to the requirement of torque and load, so select stepper motor, its maximum rotation load is comparatively stable, and the stepper motor of 12V can ensure its power, and work can be carried out by battery as power supply, the voltage stabilizing chip also adding 5-12V by USB is powered.

The utility model can be set to further: described motor drive plate model elects MCT600 as.

The driving stepper motor interface that MCT600 is provided with and the rotating of start stop switch and the function of stall; and the interface of speed-regulating potentiometer; under meeting the prerequisite of primary demand of the present utility model; also be provided with; the power supply current-limiting protection of load overload protection and power safety module, improve security of the present utility model.

The utility model can be set to further: described motor outside is also arranged with sheath body, and described start stop switch is arranged at the outer surface of sheath body.

By sheath body, motor is fixed, prevent motor directly exposed in outside, cause motor to be very easy to stuckly affect the life-span under the impact of external dust.

The utility model can be set to further: described sheath body is provided with through hole, and the knob of described speed-regulating potentiometer extends the outer surface of sheath body by through hole.

Be arranged at other positions compared to by knob, user is more prone to realize speed governing in use.

Preferably, the end face of described upper clamping block is set to arcwall face, and the corresponding described arcwall face of top shape of described chute is arranged.Be set to square in hinge structure, reduce the possibility of wearing and tearing, two play dust-proof effect further, and dust is not easily entered from end face.

Preferably, the two ends of described leading screw are equipped with spacing block set.By the setting of spacing block set, leading screw in use upper and lower play can be prevented.

Compared to prior art, the utility model creates following beneficial effect: control motor by start stop switch and realize rotating, thus controls the upper and lower slippage of screw turns drive slip base, and structure is simple, substantially reduces human cost, and electric control structure safe ready.
