Background
The jig is a tool for carpenters, ironmen, pincers, machines, electric controls and other handicrafts, and is mainly used as a tool for assisting in controlling positions or actions, the design of the jig is basically established in logic, and similar jigs can be generated respectively because of being used in different time and places; the existing jig has certain defects when in use, for example, the height of the jig can not be adjusted for workers with different heights, so that the worker is not suitable for different heights, and therefore, the adjustable parallelism jig is provided.
SUMMERY OF THE UTILITY MODEL
The present invention is directed to a parallelism-adjustable fixture, so as to solve the problems of the related art.
In order to achieve the purpose, the utility model provides the following technical scheme:
the utility model provides an adjustable depth of parallelism tool, includes the tool base, the top of tool base is provided with the tool main part of liftable, install adjustment mechanism between tool base and the tool main part, realize that tool main part terminal surface parallel goes up and down in step.
Further, adjustment mechanism includes two lower backup pads of symmetric connection at tool base up end, the one end lateral wall that two lower backup pads kept away from each other articulates there is oblique ascending lower bracing, the lower terminal surface symmetric connection of tool main part has two last backup pads that correspond with the lower backup pad, the one end lateral wall that two last backup pads kept away from each other articulates there is oblique ascending last bracing, the lower bracing that lies in same one side is connected on the lateral wall of same nut with last bracing, the screw thread is pegged graft on two nuts has same screw rod, the screw rod makes it can't be controlled about through stop device is spacing, the screw rod is rotated, make two nuts remove to opposite or opposite direction, reach tool main part lift adjustment's effect.
Furthermore, the internal threads of the two nuts are arranged in opposite directions, and two sections of external thread structures matched with the corresponding nuts are arranged on the screw rod.
Further, stop device is including rotating the slider of connection at the screw rod tip, and slider sliding connection is in the bar spout that the straight board lateral wall was seted up, and the lateral wall lower extreme of straight board rotates the stand of connection on the tool base is fixed to the lower extreme, and stand and screw rod do not lie in same vertical face.
Furthermore, the corners of the upper end surface of the jig base are connected with four sleeves in a matrix mode, the guide support rods with the upper ends connected to the lower end surface of the jig main body are inserted in the sleeves, and the bottoms of the sleeves are connected with springs with the upper ends abutted to the lower ends of the guide support rods.
Compared with the prior art, the utility model has the beneficial effects that: this adjustable depth of parallelism tool rotates the screw rod, and under stop device's is spacing, the screw rod can not remove about to under threaded connection's drive, two nuts remove to opposite or opposite direction, bracing and last bracing under the promotion, thereby reach the purpose of adjusting the tool main part and go up and down, only need positive and negative direction to twist soon the screw rod and can adjust, convenient operation, simple structure has very strong practicality.
Drawings
FIG. 1 is a schematic view of the structure of the present invention.
In the figure: the jig comprises a jig base 1, a jig main body 2, a lower supporting plate 3, an upper supporting plate 4, a lower inclined support 5, an upper inclined support 6, a nut 7, a screw 8, a stand column 9, a straight plate 10, a sliding block 11, a sleeve 12 and a guide supporting rod 13.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution:
the utility model provides an adjustable depth of parallelism tool, includes tool base 1, and the top of tool base 1 is provided with the tool main part 2 of liftable, installs adjustment mechanism between tool base 1 and the tool main part 2, realizes that 2 terminal surfaces of tool main part are parallel to go up and down in step.
Wherein, adjustment mechanism includes two bottom suspension fagging 3 of symmetric connection at 1 up end of tool base, the one end lateral wall that two bottom suspension fagging 3 kept away from each other articulates there is oblique ascending lower bracing 5, the lower terminal surface symmetric connection of tool main part 2 has two last backup pad 4 that correspond with bottom suspension fagging 3, the one end lateral wall that two last backup pad 4 kept away from each other articulates there is oblique ascending last bracing 6, the lower bracing 5 that lies in same one side and last bracing 6 connect on the lateral wall of same nut 7, screw peg graft and have same screw rod 8 on two nuts 7, screw rod 8 passes through stop device spacing and makes it can't remove about, the internal thread of two nuts 7 is opposite direction setting, be provided with two sections external screw thread structures that match with corresponding nut 7 on screw rod 8, rotate screw rod 8, make two nuts 7 remove to opposite direction or opposite direction, reach tool main part 2 lift adjustment's effect.
Wherein, stop device is including rotating slider 11 of connection at the 8 tip of screw rod, slider 11 sliding connection is in the bar spout that the straight plate 10 lateral wall was seted up, the lateral wall lower extreme of straight plate 10 rotates the stand 9 of connection on the lower extreme is fixed on tool base 1, and stand 9 is not located same vertical face with screw rod 8, when rotating screw rod 8, screw rod 8's height also can change along with the change of lower bracing 5 slopes, at this moment, slider 11 slides to relevant position in the bar spout of straight plate 10, and slider 11 stop position is coaxial with screw rod 8 all the time.
In addition, the corners of the upper end surface of the jig base 1 are connected with four sleeves 12 in a matrix manner, the sleeves 12 are internally inserted with guide support rods 13 of which the upper ends are connected to the lower end surface of the jig main body 2, and the bottoms of the sleeves 12 are connected with springs of which the upper ends are propped against the lower ends of the guide support rods 13, so that the supporting effect is achieved, and the stability is enhanced.
This adjustable depth of parallelism tool, tool base 1 is fixed on ground or workstation, rotates screw rod 8, and under stop device's is spacing, the screw rod 8 can not remove about to under threaded connection's drive, two nuts 7 are to moving in opposite directions or opposite direction, and bracing 5 and last bracing 6 under the promotion, thereby reach the purpose of adjusting 2 lifts of tool main part, only need positive and negative direction to twist soon screw rod 8 can adjust, convenient operation, simple structure has very strong practicality.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
