Description
Technical Field
The invention relates to a jig, in particular to a screwing jig.
Background
The product is not contacted with the rod-shaped parts with the studs fixed on the shell of the product through the nuts in the assembly process, but in the fixing process, the nuts are generally fixed inside the shell, the rod-shaped parts are fixed outside the shell, and the fixing of the rod-shaped parts on the shell can be realized by penetrating the studs on the rod-shaped parts through the through holes formed in the shell in advance and then screwing the stud parts with the nuts positioned in the shell.
However, the inventor found that since the rod-shaped member and the nut are positioned inside the housing when they are screwed, in order to avoid the following rotation of the nut when the rod-shaped member or the column-shaped member is rotated, the worker needs to hold the nut positioned inside the housing by an additional tool such as a vice, a wrench, etc., and then rotate the rod-shaped member, which is not only laborious but also very complicated. Meanwhile, in the screwing process, because the screws are manually screwed by using two hands, the screwing force of the screws cannot meet the assembly requirement of a product, and therefore, the screw is loosened when in use.
Disclosure of Invention
The invention aims to provide a screwing jig which can conveniently screw a rod-shaped component with a stud on a product shell and improve the pretightening force of the rod-shaped component after screwing so as to meet the use requirement.

The pressing plate is arranged between the first frame body and the second frame body, is respectively connected with the first frame body and the second frame body in a sliding manner, and is used for carrying out linear sliding along the height direction of the first frame body and the second frame body;
The turntable mechanism is rotatably arranged on the pressing plate and is provided with a part which penetrates through the pressing plate to clamp the rod-shaped component; the turntable mechanism is also used for driving the rod-shaped component to rotate by taking the axis of the stud as the center when rotating;
the jig body is arranged between the first frame body and the second frame body and used for fixing the shell and the screw cap;
After the shell and the screw cap are respectively fixed, the shell is used for covering the screw cap, the screw cap is also abutted against the side wall of the through hole formed in the shell and coaxial with the through hole, and the rod-shaped component is also used for being clamped by the turntable mechanism and coaxial with the screw cap fixed by the jig body.

In addition, since the pressing plate is slidably disposed on the first frame body and the second frame body, the turntable mechanism is rotatably disposed on the pressing plate, and part of the turntable mechanism penetrates the pressing plate to clamp the rod-shaped component, and the rod-shaped component can be directly coaxial with the nut on the jig body after being clamped. Therefore, when in actual use, a worker only needs to drive the rod-shaped component to rotate by taking the axis of the stud as the center through the turntable mechanism, so that screwing of the stud and the nut can be realized, and when the operation is convenient, the lower pressing plate also utilizes self gravity and sliding fit with the first frame body and the second frame body in the screwing process of the stud and the nut, so that the lower pressing plate can also drive the turntable mechanism to gradually descend in the screwing process of the stud and the nut, and the phenomenon that the rod-shaped component is separated from the turntable mechanism when being screwed with the nut is avoided. In addition, because the screw bolt is fixed by the jig body in the screwing process of the screw bolt and the screw cap, the following rotation phenomenon of the screw cap caused by the rotation of the rod-shaped component can be avoided, and the screw bolt and the screw cap can be easily screwed, so that the practical use requirement is met.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the following detailed description of the embodiments of the present application will be given with reference to the accompanying drawings. However, those of ordinary skill in the art will understand that in various embodiments of the present application, numerous technical details have been set forth in order to provide a better understanding of the present application. The claimed application may be practiced without these specific details and with various changes and modifications based on the following embodiments.
The first embodiment of the present invention relates to a tightening jig in which a rod-shaped member 6 with a stud is screwed to a side wall of a housing 8 having a through hole by a nut 9, as shown in fig. 1 and 3. Specifically, as shown in fig. 1, the screwing tool comprises: the device comprises a first frame body 1, a second frame body 2 arranged opposite to the first frame body 1, and a pressing plate 3 arranged between the first frame body 1 and the second frame body 2. Wherein, both ends of the pressing plate 3 are respectively in sliding connection with the first frame body 1 and the second frame body 2, so that the pressing plate 3 can be used for performing linear sliding along the height direction of the first frame body 1 and the second frame body 2.
Next, as shown in fig. 1 and 3, the screwing jig of the present embodiment further includes: a turntable mechanism 4 rotatably provided on the pressing plate 3, and the turntable mechanism 4 has a portion penetrating the pressing plate 3 for catching the rod-like member 6, and the turntable mechanism 4 is further for rotating the rod-like member 6 centering on the axis of the stud 61 when rotating.
As shown in fig. 1 and 3, the tightening jig according to the present embodiment further includes: a jig body 7 disposed between the first frame body 1 and the second frame body 2, the jig body 7 being for fixing the housing 8 and the nut 9.
In the actual use process, as shown in fig. 4, after the shell 8 and the nut 9 are respectively fixed by the jig body 7, the shell 8 can directly cover the nut 9, and the nut 9 is also used for propping against the side wall of the through hole formed in the shell 8 and is coaxial with the through hole. Meanwhile, the rod-like member 6 can be coaxial with the nut 9 fixed by the jig body 7 after being caught by the turntable mechanism 4.
Through the above, it is easy to find that, in the actual operation process, the staff can drive the rod-shaped component 6 by the turntable mechanism 4 to rotate by taking the axis of the stud 61 as the center, so that the screwing of the stud 61 and the nut 9 can be realized, and in the process of screwing the stud 61 and the nut 9, the lower pressing plate 3 also utilizes the gravity of the lower pressing plate 3 and the sliding fit of the lower pressing plate with the first frame body 1 and the second frame body 2, so that the turntable mechanism 4 can be driven by the lower pressing plate 3 to gradually descend in the process of screwing the stud 61 and the nut 9, thereby avoiding the phenomenon that the rod-shaped component 6 is separated from the turntable mechanism 4 when screwing the nut 9. In addition, since the screw bolt 61 is fixed by the jig body 7 in the screwing process with the screw cap 9, the following rotation phenomenon of the screw cap 9 caused by the rotation of the rod-shaped component 6 can be avoided, and the screw bolt 61 and the screw cap 9 can be easily screwed, so that the practical use requirement can be met.
Specifically, as shown in fig. 1 and 3, the first frame 1 includes: the first side plate 11 is vertically arranged, the first lower baffle 12 and the first upper baffle 13 are arranged along the height direction of the first side plate 11, and the first guide rod 14 is vertically arranged between the first upper baffle 13 and the first lower baffle 12. And the second frame 2 comprises: the second side plate 21 is vertically arranged, the second lower baffle 22 and the second upper baffle 23 are arranged along the height direction of the second side plate 21, and the second guide rod 24 is vertically arranged between the second upper baffle 23 and the second lower baffle 22. The platen 3 is slidably connected to the first guide bar 14 and the second guide bar 24 at both ends thereof. As can be seen from this, the first guide bar 14 and the second guide bar 24 can guide the vertical sliding of the platen 3, so that the platen 3 can slide along the longitudinal direction of the first guide bar 14 and the second guide bar 24. And, in order to improve the stability of whole tool of screwing, be connected through bottom plate 5 between first curb plate 11 and the second curb plate 21, simultaneously, tool body 7 sets up on bottom plate 5 to make whole tool of screwing can become one whole, make the tool of screwing can satisfy different demands of putting. In addition, in the present embodiment, the first upper baffle 13 and the second upper baffle 23 are on the same plane, and the first lower baffle 12 and the second lower baffle 22 are on the same plane, so that when the pressing plate 3 slides, the distance that the pressing plate 3 slides upwards can be limited by the first upper baffle 13 and the second upper baffle 23, so as to ensure that the pressing plate 3 cannot slide out of the first guide rod 14 and the second guide rod 24, and the distance that the pressing plate 3 slides downwards can be limited by the first lower baffle 12 and the second lower baffle 22, so that effective bearing of the pressing plate 3 can be realized.
In addition, in order to facilitate screwing of the rod-like member 6 to the housing 8 having different height dimensions, in the present embodiment, it is preferable that the first lower baffle 12 is slidably provided on the first side plate 11 and the second lower baffle 22 is slidably provided on the second side plate 21, so that the first lower baffle 12 and the second lower baffle 22 can slide linearly in the height direction of the first side plate 11 and the second side plate 21. It is thus readily apparent that when the actual height dimensions of the housing 8 are changed, the positions of the first and second lower baffles 12, 22 on the first and second side plates 11, 21, respectively, can be adjusted by the staff to meet the assembly requirements of the rod-like member 6 with the housing 8.
It should be noted that, in the present embodiment, as shown in fig. 1, the jig body 7 includes: a vertically disposed tailgate 71, first and second positioning members 72, 73 oppositely disposed on the tailgate 71, and a positioning block 74 disposed on the tailgate 71 for positioning the nuts 9. The rear baffle 71 is located between the first side plate 11 and the second side plate 21, the first positioning member 72 and the second positioning member 73 are disposed opposite to each other along the width direction of the rear baffle 71, the first positioning member 72 and the second positioning member 73 cooperate with each other to clamp the housing 8, and the positioning block 74 is disposed against a side wall of the housing 8, in which the through hole is formed, from inside the housing 8.
Specifically, as shown in fig. 2, the positioning block 74 is provided with a positioning groove 741 for fixing the nut 9, and the positioning groove 741 has a polygonal shape similar to the nut 9, while in the present embodiment, the nut 9 is a conventional hexagonal nut, and the same positioning groove 741 has a hexagonal shape, so that the nut 9 is prevented from rotating randomly after being placed in the positioning groove 741. In addition, in order to enable the rod-shaped component 6 to directly pass through the positioning block 74 to be mutually screwed with the nut 9 positioned in the shell 8, the bottom of the positioning groove 741 is also provided with a through hole 743 for passing through the stud 61 of the rod-shaped component 6, so that the stud 61 of the rod-shaped component 6 can directly pass through the positioning block 74 through the through hole to realize screwing with the nut 9.
Meanwhile, as a preferred solution, in the present embodiment, as shown in fig. 2, a channel 742 that communicates with the positioning groove 741 is further formed on a side of the positioning block 74 facing away from the rear baffle 71, and the caliber of the channel 742 is larger than the outer diameter of the nut 9, and the channel 742 can be used for horizontally moving out the nut 9. It can be seen that, as shown in fig. 4, when the stud 61 of the rod-shaped component 6 is fully screwed with the nut, the worker can pass through the channel 742 formed on the positioning block 74, so that the shell 8 can be directly taken out from the front side of the jig body 7 after the rod-shaped component 6 is screwed with the nut 9, thereby facilitating the worker to remove the shell 8 with the rod-shaped component 6 from the jig body 7.
In addition, in order to ensure that the first positioning member 72 and the second positioning member 73 do not cause damage to the housing 8 when the housing 8 is caught, in this embodiment, as shown in fig. 2, a side of the first positioning member 72 for abutting against the housing 8 and a side of the second positioning member 73 for abutting against the housing 8 are both flexible sides. By the flexible sides of the first positioning member 72 and the second positioning member 73, damage to the housing 8 when the housing 8 is caught by the first positioning member 72 and the second positioning member 73 can be avoided.
As shown in fig. 1 and 3, the turntable mechanism 4 according to the present embodiment includes: a rotary table 41 rotatably provided on the pressing plate 3, a positioning sleeve 42 provided on the rotary table 41 for clamping the rod-shaped member 6, and a driving member 43 fixedly connected with the rotary table 41 for driving the rotary table 41 to rotate. The positioning sleeve 42 is fixed coaxially with the center of the turntable 41, and passes through the pressing plate 3 to be in rotary fit with the pressing plate 3. Meanwhile, in this embodiment, in order to meet the practical use requirement, the driving member 43 is a handle disposed on the turntable 41, and the handle is eccentrically disposed with respect to the turntable 41, so that in the practical use process, a worker can drive the turntable 41 and the positioning sleeve 42 to rotate around the center of the turntable 41 through the handle, thereby driving the rod member 6 to rotate, and realizing screwing of the stud 61 of the rod member 6 and the nut 9.
Of course, in the practical use process, in order to further improve the installation efficiency of the rod-shaped member 6, an automatic screwing manner may be adopted between the rod-shaped member 6 and the nut 9. Thus, the driving element 43 may also be an automated driving device, for example: as shown in fig. 5, the driving member 43 includes a motor 431 and a main shaft 432 connected to the motor 431, and the main shaft 432 is coaxially connected to the center of the turntable 41. Therefore, in practical application, the motor 431 can drive the turntable 41 to rotate through the main shaft 432, so that the rod-shaped member 6 and the nut 9 can be automatically screwed. Meanwhile, as a preferable scheme, in order to control the screwing force between the rod-shaped component 6 and the nut 9, the motor is prevented from being inconvenient to detach due to overlarge screwing force between the rod-shaped component 6 and the nut 9, a torque sensor (not shown in the figure) can be arranged on the motor in actual use, the torque sensor is used for testing the torque provided by the motor when the rod-shaped component 6 is screwed with the nut 9, a main control system which is electrically connected with the torque sensor and the motor respectively can be additionally arranged, the main control system can receive the torque value uploaded by the torque sensor in real time, and once the torque value uploaded by the torque sensor reaches a preset value, the motor can be immediately closed by the main control system, so that the motor stops working, and therefore, the consistency of the screwing force when each rod-shaped component 6 is screwed with each nut 9 can be ensured, and the phenomenon that the screwing force is overlarge between the rod-shaped component 6 and the nut 9 is avoided.
A second embodiment of the present invention relates to a screwing jig, which is a further improvement of the first embodiment, and in this embodiment, as shown in fig. 6 and 7, the first frame 1 further includes: the first resilient member 15 is sleeved on the first guide rod 14, and the second frame 2 further includes: and a second resilient member 25 fitted over the second guide bar 24. Wherein the first resilient member 15 and the second resilient member 25 are adapted to abut against the platen 3, respectively.
Specifically, in the present embodiment, as shown in fig. 6 and 7, the first resilient member 15 and the second resilient member 25 may each employ springs, so that when the pressing plate 3 is pressed down, the pressing plate 3 may be supported by the two springs, so as to avoid the pressing plate 3 from crushing the rod-shaped member 6 due to its own large self weight during the lowering process. Meanwhile, after the rod-shaped component 6 is screwed on the shell 8, the pressing plate 3 can be driven to linearly move upwards along the length direction of the first guide rod 14 and the second guide rod 24 by the resilience force of the two springs, so that the pressing plate 3 can be automatically reset, a worker can conveniently take out the shell 8 provided with the rod-shaped component 6 from the jig body 7, and meanwhile, the worker can conveniently fix the subsequent shell on the jig body 7. In addition, as a preferable scheme, in the practical application process, the lengths of the two springs can be properly shortened to ensure that the lengths of the two springs are smaller than the sliding stroke of the pressing plate 3, so that the rebound resistance of the pressing plate 3 when sliding downwards can be reduced in the process of sliding downwards, and the screwing of the rod-shaped component 6 and the nut 9 is easier to operate.
A third embodiment of the present invention relates to a screwing tool, which is a further improvement on the basis of the first embodiment, and the main improvement is that: as shown in fig. 8 and 9, in the present embodiment, the jig body 7 further includes: a first shelf 75 and a second shelf 76 disposed opposite the tailgate 71.
Specifically, as shown in fig. 8 and 9, the first and second stoppers 75 and 76 are for being disposed opposite to each other in the width direction of the tailgate 71, and the first and second stoppers 75 and 76 are for abutting against the side of the case 8 facing away from the tailgate 71. The first stopper 75 includes a first stopper 751 and a first stopper arm 752 provided on the first stopper 751; and the second catch 76 includes a second catch 761, a second catch arm 762 disposed on the second catch 761. Also, in the present embodiment, the first stopper 752 may be rotatably provided on the first stopper 751, and the second stopper 762 may be rotatably provided on the second stopper 762 as well.
Through the above, it is easy to find that, in the actual use process, the side, away from the back plate 71, of the housing 8 can be blocked by the first blocking arm 752 and the second blocking arm 762, that is, the side, away from the back plate 71, of the housing 8 can be propped against the first blocking arm 752 and the second blocking arm 762, so that the firmness of the fixture body 7 in fixing the housing 8 can be further improved, and the screwing operation between the rod-shaped component 6 and the screw cap 9 is further facilitated. When the rod-shaped component 6 and the nut 9 are screwed together, the worker can rotate the first blocking arm 752 and the second blocking arm 762, so that the first blocking arm 752 and the second blocking arm 762 can be separated from one side of the shell 8, which is away from the rear baffle 71, and the shell 8 can be horizontally moved out from the front side of the jig body 7, so that the shell 8 can be conveniently taken out.
Of course, it should be noted that, to satisfy different operating habits, the first blocking arm 752 and the first stop 751, and the second blocking arm 762 and the second stop 761 may be slidably connected, so that the first blocking arm 752 and the second blocking arm 762 may slide linearly in opposite or opposite directions to achieve the abutment and separation of the side of the housing 8 facing away from the rear baffle 71.
A fourth embodiment of the present invention relates to a screwing tool, which is a further improvement of the first embodiment, and the main improvement is that in this embodiment, as shown in fig. 10, a hook 10 is further provided on the pressing plate 3, and the hook 10 is used for hooking the first upper baffle 13.
From the above, it is found that, when the rod-like member 6 is screwed with the screw cap 9, the pressing plate 3 can slide to the top of the first side plate 11 and the second side plate 21 along the length direction of the first guide rod 14 and the second guide rod 24, and then the first upper baffle 13 is hooked by the hook 10, so that the whole turntable mechanism 4 can be firmly fixed on the first upper baffle 13 and the second upper baffle 23, thereby further facilitating the operator to take out the housing 8 with the rod-like member mounted from the jig body 7.
It should be noted, of course, that during the actual operation, the hook 10 directly hooks the second baffle 23, and the whole turntable mechanism 4 is fixed by hooking the second baffle 23.
It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples of carrying out the invention and that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
