Technical field

The utility model relates to a kind of drivings of workpiece cleaning system to protect structure.

Background technique

Workpiece cleaning system, mainly by thick washing machine structure, ultrasonic cleaning agency, fine purifiation mechanism, cut water dispenser structure, dryer The cleaning structures such as structure, cooling body composition.Workpiece, in conveying mechanism (its driving group mainly to be worked by stepping of step motion Part and the transfer assembly of conveying workpieces is constituted under driving assembly driving) under transmission, into each wiper mechanism, carry out corresponding Cleaning.

Summary of the invention

The purpose of this utility model is to provide a kind of drivings of workpiece cleaning system to protect structure, it avoids mechanical breakdown Cause the driving assembly lost motion phenomenon of conveying mechanism to occur, prevents driving assembly from stopping that itself is caused to overload or pass not in time The damage of the other structures such as sending component.

The purpose of this utility model is achieved through the following technical solutions: a kind of driving protection structure of workpiece cleaning system, It includes set on the torque protection component between driving assembly and transfer assembly；The torque protection component includes being sheathed on driving Expansion set outside the power spindle of component is sheathed on expansion set outer wall lower part and to enable expansion set hold tightly using taper fit between expansion set dynamic The swelling axle sleeve of axis, the fixed ring of advocating are set to tooth form ball holding ring in the middle part of swelling axle sleeve on periphery wall, correspondence is arranged in tooth Several balls in each accommodation groove of shape ball holding ring are set to outside swelling axle sleeve and upper surface is equipped with by bearing turning set With the driving sleeve of the arc groove of ball corresponding matching, be sheathed on the floating outside tooth form ball holding ring and being supported on ball Outer ring is sheathed on swelling axle sleeve outer wall top and expansion shaft can cover the torque adjustment part for moving axially and fixing relatively, be set to and float Between dynamic outer ring and torque adjustment part and pushing floating outer ring is adjacent to the cyclic spring unit of ball and is set on floating outer ring Side and the floating that matches with floating outer ring upper surface are close to inductor；The transmission shaft of the driving sleeve and transfer assembly is coaxial It is fixed；The power spindle is arranged in transmission shaft.

For the prior art, utility model has the advantages that

(1) it is rotated not once there is power spindle with transmission shaft by floating outer ring and floating close to the setting of inductor Can be synchronous, the pressure of cyclic spring unit that ball overcomes slips away arc groove, so that occurring between swelling axle sleeve and driving sleeve It skids, while pushing up floating outer ring on ball, float and sense floating outer ring close to signal is issued in time to stop close to inductor The work of driving assembly, not only having prevented torque between power spindle and transmission shaft is more than that limit value causes mechanical failure, but also energy is in time Shutdown avoids driving assembly lost motion, and convenient discovery in time, maintenance.

(2) using close to cam and rotation close to the cooperation of inductor, the delivery precision of transfer assembly is further increased.

Specific embodiment

The content of the present invention is described in detail with embodiment with reference to the accompanying drawings of the specification:

It is as shown in Figures 3 to 8 a kind of implementation of the driving protection structure of workpiece cleaning system provided by the utility model It illustrates and is intended to.

A kind of driving protection structure of workpiece cleaning system, it includes being set between driving assembly 15 and transfer assembly 16 Torque protection component；The torque protection component includes the expansion set 1 being sheathed on outside the power spindle 151 of driving assembly 15, is arranged Expansion set 1 is enabled to hold the swelling axle sleeve 2, solid of power spindle 151 tightly using taper fit in 1 outer wall lower part of expansion set and between expansion set 1 Surely the tooth form ball holding ring 3 that is located on 2 middle part periphery wall of swelling axle sleeve, correspondence are arranged in each of tooth form ball holding ring 3 Several balls 4 in a accommodation groove 31, be set to that swelling axle sleeve 2 is outer by 5 turning set of bearing and upper surface be equipped with it is corresponding with ball 4 The driving sleeve 6 of the arc groove 61 of cooperation is sheathed on the floating outer ring that tooth form ball holding ring 3 is outer and is supported on ball 4 7, be sheathed on 2 outer wall top of swelling axle sleeve and can opposite expansion shaft set 2 move axially and fixed torque adjustment part 9, be set to it is floating Between dynamic outer ring 7 and torque adjustment part 9 and pushing floating outer ring 7 is adjacent to the cyclic spring unit of ball and is set to floating outer ring 7 tops and the floating that matches with 7 upper surface of floating outer ring are close to inductor 10；The driving sleeve 6 and transfer assembly 16 Transmission shaft 161 is coaxially fixed；The power spindle 151 is arranged in transmission shaft 161.

The cyclic spring unit includes padding the washer 11 being set on 9 lower end surface of torque adjustment part and positioned at floating outer ring Disk spring 12 between 7 and washer 11.

Pressure (i.e. the limit value of torque) in order to facilitate the annular Flexible element of adjustment to floating outer ring 7, the torque tune One integral piece 9 moves axially adjustment by helicitic texture and swelling axle sleeve 2.

The driving protection structure of the workpiece cleaning system further includes on the protractor input shaft 152 of driving assembly 15 Rotational angle monitoring assembly；The rotational angle monitoring assembly include axially spaced-apart be set to input shaft 152 on and boss In the different two or more radially of input shaft 152 close to cam 13 and be fixedly arranged on protractor shell 153 and with close to convex 13 corresponding matchings are taken turns to monitor more than two rotations of 152 rotational angle of input shaft close to inductor 14.

When input shaft 152 carries out rotation stepping with rotational angle for 180 °, close to cam 13 and rotate close to inductor 14 each settings two, two included angles close to 13 lug boss of cam in 152 axis projection of input shaft are rotated with two close to induction Device 14 is 180 ° in the sum of included angle of 152 axis projection of input shaft.When one of rotation is sensed close to inductor 14 It corresponds to close to 13 lug boss of cam after, another rotation will be after 180 ° of input shaft accurate rotational just close to inductor 14 It can sense that it is corresponded to close to the close of 13 lug boss of cam, with this continuous alternately induction, so that the conveying essence of transfer assembly It spends more accurate.
