Detailed Description
The utility model provides a connector tightening device, which is further described in detail below in order to make the purpose, technical scheme and effect of the utility model more clear and definite. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Referring to fig. 1 to 6, the present utility model provides a connector tightening device. The drawings are only for the purpose of illustrating the structural principles and are not to scale with respect to actual products. The terms "first," "second," and the like, herein are merely used for convenience in description and are not intended to limit the utility model. For ease of description, certain directional terms are used herein inevitably, with "front" as used herein referring to a direction toward the outside of the chuck and "rear" referring to a direction opposite to the "front; it should be noted that these directional terms are merely for convenience in explaining the structural principle, and are not intended to limit the present utility model. Fig. 2 and 3 show only the structures related to the utility model, and other structures not related to the utility model are not shown. Fig. 7 shows only one embodiment of the connector tightening device, and does not represent that the connector tightening device can only be used for tightening a specific connector.
Referring to fig. 1 to 7, the connector tightening device includes a housing 9, in which a clamping mechanism and a driving motor 2 are disposed, and an output shaft of the driving motor is provided with a driving gear 21; the clamping mechanism comprises a mounting seat 19 and a chuck 1 rotatably connected with the mounting seat, a plurality of clamping jaws 11 are arranged in the chuck, and a driven gear 22 is arranged on the chuck and meshed with the driving gear.
Preferably, three clamping jaws are provided in the chuck, and a clamping cylinder 32 is provided in the housing for controlling clamping or unclamping of the clamping jaws. That is, when machining is required, the clamping jaw is clamped, and after machining is completed, the clamping jaw is loosened.
The clamping and unclamping of the three-jaw chuck can be achieved in a number of ways, and a solution is provided herein (not limited to this in practice): referring to fig. 2 and 5, a first slide plate 71 is provided in the housing, and is capable of linearly and reciprocally moving in a direction parallel to the axial direction of the positioning sleeve; a connecting seat 33 is arranged on the first sliding plate, and the end part of a piston rod of the clamping cylinder is connected with the connecting seat; the connecting seat is connected with a push block 13, three lock plates 12 are arranged on the push block, and each clamping jaw of the three-jaw chuck is respectively connected with the corresponding lock plate.
In practical application, the push block 13 includes an inner member 131 and an outer member 133, the lock plate is connected with the inner member, the connecting seat is connected with the outer member, the inner member is connected with the outer member through a bearing 132, and the outer member and the connecting seat do not rotate together when the lock plate and the inner member rotate.
As shown in fig. 6, the contact surface of each lock plate and the corresponding jaw is a ramp 100, so that axial movement of the lock plate will cause radial movement of the jaw to effect clamping or unclamping. While the axial movement of the lock plate is controlled by a lock cylinder.
Further, a pre-clamping cylinder 31 is arranged in the shell, and the end part of a piston rod of the pre-clamping cylinder is connected with the rear end of the clamping cylinder. When in actual use, the piston rod of the pre-clamping cylinder stretches out and then moves forwards for a certain distance with the clamping cylinder, the connecting seat, the locking piece and the locking plate, and at the moment, the clamping jaws gather but are not clamped, so that only a pre-tightening effect is achieved; further, after the piston rod of the clamping cylinder extends out, the connecting seat, the locking block and the locking plate move forwards for a certain distance again, and the clamping jaw is completely clamped at the moment.
As shown in fig. 5, further, a positioning sleeve 44 is provided in the chuck, which positioning sleeve is axially movable with respect to the chuck; the rear end of the sleeve is provided with a sensing rod 612, and a tightening cylinder 41 and a first sensor 611 for detecting the sensing rod are arranged in the housing. The positioning sleeve and the chuck are coaxially arranged. The front end of the positioning sleeve is provided with a concave cavity (not visible in the figure), and the rear end of the connector can extend into the concave cavity of the positioning sleeve to abut against the sleeve, so that the connector is axially positioned. In practice, the connector is inserted into the chuck until the first sensor detects the sensing rod, indicating that the connector is in place.
Further, a second slide plate 72 is arranged in the shell, and can linearly reciprocate, and the moving direction is parallel to the axial direction of the positioning sleeve; the second slide plate is connected with the positioning sleeve through the connecting plate 43, and the second slide plate is also provided with a sensing piece 622; a second sensor 621 for detecting the sensing piece is provided in the housing. When the piston rod of the jacking cylinder stretches out, the second sliding plate, the connecting plate and the positioning sleeve are driven to linearly move, so that the axial positioning of the connecting piece is completed.
In operation, rotation of the chuck clamps the nut of the connector C in rotation, the first portion C1 of the connector (i.e., the portion that faces outwardly and contains the nut) rotates without axial movement, and the second portion C2 of the connector (i.e., the portion that faces inwardly and does not contain the nut) moves axially, as does the positioning sleeve. Correspondingly, the connecting plate connected with the positioning sleeve, the second sliding plate and the sensing piece arranged on the second sliding plate can also linearly move. The relative positions of the second sensor and the sensing piece are used for judging whether the connector is axially positioned.
Further, a third sliding plate 73 is arranged in the shell and can linearly reciprocate, and the moving direction of the third sliding plate is parallel to the axial direction of the positioning sleeve; the second sensor 621 is disposed on the third slider; an adjusting screw rod 81 is arranged in the shell, a third sliding plate is connected with the adjusting screw rod, and a hand wheel 82 of the adjusting screw rod extends out of the shell. This arrangement facilitates adjustment of the position of the second slider to control the specific location at which the nut is threaded into place.
The first sensor and the second sensor may be implemented in various manners, and preferably, the first sensor and the second sensor may be implemented by a proximity switch or the like.
For ease of understanding, the working principle of the connector tightening device is briefly described below.
(1) Placing the connector into the chuck;
(2) The piston rod of the pre-clamping cylinder extends out to limit the connector;
(3) The piston rod of the jacking cylinder stretches out to push the positioning sleeve to move forwards until the connector finishes axial positioning;
(4) The piston rod of the clamping cylinder stretches out to clamp the nut C9 of the connector;
(5) The driving motor is started and drives the chuck to rotate, and the positioning sleeve slowly moves forward until the second sensor detects the induction piece, and the driving motor stops running.
(6) The pre-clamping cylinder, the jacking cylinder and the clamping cylinder are reset, and the whole process is finished.
It will be understood that equivalents and modifications will occur to those skilled in the art based on the present utility model and its spirit, and all such modifications and substitutions are intended to be included within the scope of the present utility model.
