Abstract
This utility model relates to the protection device of a kind of near work spray gun, and including spray gun, the outside of described spray gun arranges a sleeve, is provided with back-moving spring between described spray gun and described sleeve；Described sleeve is connected with leading screw feed mechanism by retainer ring, and described sleeve is provided with the proximity switch of detection spray gun rollback, and described proximity switch is connected with control circuit, and described control circuit is connected with described leading screw feed mechanism.This utility model can stop advancing spray gun and driving spray gun to return back to home, it is to avoid the damage of spray gun when spray gun touches with painted object or other object.
Description
Technical field
This utility model relates to the technical field of automatic spray apparatus, is specifically related to a kind of near work spray gun
Protection device.
Background technology
In spraying production process automatically, various beyond thought situation can occur, such as: painted object table
The concavo-convex situation in face beyond requiring, laser ranging system because of fault dysmetria, painted object to level sensor therefore
Barriers etc., the most easily make spray gun and painted object or other object generation rigid collision, thus damage spray gun and make
Forming apparatus is shut down.
Utility model content
The purpose of this utility model is to provide the protection device of a kind of near work spray gun, in spray gun and spraying
When object or other object touch, stop advancing spray gun and driving spray gun to return to home, it is to avoid
The damage of spray gun.
The purpose of this utility model is realized by following technical proposals: the protection of a kind of near work spray gun
Device, including spray gun, the outside of described spray gun arranges a sleeve, sets between described spray gun and described sleeve
There is back-moving spring；Described sleeve is connected with leading screw feed mechanism by retainer ring, and described sleeve is provided with detection
The proximity switch of spray gun rollback, described proximity switch is connected with control circuit, described control circuit and described silk
Thick stick feed mechanism connects.
Preferably, the head of described spray gun is provided with baffle ring, and one end of described back-moving spring is against described sleeve
Rear portion, the other end of described back-moving spring is against on described baffle ring.
This utility model compared with prior art has the advantage that
This utility model detects spray gun because being transported by the rollback of external force generation relative sleeve in real time by proximity switch
Dynamic, control circuit controls leading screw feed mechanism according to the signal of proximity switch and drives spray gun to return to security bit
Putting, protection spray gun normally works.
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model preferred embodiment.
Detailed description of the invention
Seeing Fig. 1, the protection device of a kind of near work spray gun, including spray gun 1, outside described spray gun
Portion arranges a sleeve 3, is provided with back-moving spring 5 between described spray gun and described sleeve；Described sleeve passes through
Retainer ring 4 is connected with leading screw feed mechanism 7, and described sleeve is provided with the proximity switch 6 of detection spray gun rollback,
Described proximity switch is connected with control circuit, and described control circuit is connected with described leading screw feed mechanism.
In the present embodiment, the front portion of described sleeve is provided with spray gun loading port, and this spray gun loading port is installed one
Individual socket cover 2, is provided with the first installing hole at the center of socket cover, and the rear portion of sleeve is provided with the second installing hole,
Spray gun 1 is installed in these two installing holes and can be along the longitudinal sliding motion of sleeve.
In the present embodiment, back-moving spring 5 is sleeved on spray gun 1, and the head of described spray gun is provided with baffle ring
8, one end of described back-moving spring 5 is against the posterior medial of described sleeve 3, described back-moving spring 5 another
One end is against on described baffle ring 8.Proximity switch 6 is fixed on the rear outside of sleeve 3 by a support,
Proximity switch and a control circuit signal connect.
In the present embodiment, described leading screw feed mechanism 7 includes leading screw, leads thick stick, servomotor 9, described
The bottom of retainer ring 4 is provided with screwed hole, and the side of described retainer ring is provided with circular hole, and described screwed hole is with described
Threads of lead screw connects, and described circular hole is slidably connected with described thick stick of leading.Described leading screw passes through bearing and two bearings
Seat is installed, and leading screw one end is in transmission connection by the output shaft of shaft coupling with servomotor；Described thick stick of leading is erected at
On two bearings.Leading screw feed mechanism is identical with prior art construction, retainer ring and the company of leading screw feed mechanism
The mode of connecing is also adopted by usual manner.Control circuit controls servomotor and drives screw turns, retainer ring, sleeve
Can move forward and backward under the promotion of leading screw with spray gun one.
In the present embodiment, during Typical spray operation, sleeve 3 and spray gun 1 synchronize to push ahead, and are advancing
During once spray gun touch painted object or other object, external force force spray gun in sleeve rollback compression
Back-moving spring 5, spray gun 1 and sleeve 3 produce relative motion to a distance set, triggering proximity switch 6
Sending signal, feed back to control circuit or control system (PLC), control circuit issues instructions to servomotor,
Servomotor drives the leading screw being connected to rotate backward promotion retainer ring 4 backward, drives the sleeve 3 in retainer ring
Retreating with spray gun 1, spray gun 1 is protected.Spray gun resets under the effect of back-moving spring, can normally enter
Enter next cycle of operation.
The above, only this utility model preferably detailed description of the invention, but protection model of the present utility model
Enclose and be not limited thereto, the technology model that any those familiar with the art discloses at this utility model
In enclosing, the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.Cause
This, protection domain of the present utility model should be as the criterion with the protection domain of claims.
