Technical Field
The utility model relates to a mechanical device, concretely relates to structure assembly height adjusting device.
Background
In the current vehicle products processed by companies, most structural components installed on a vehicle frame have the phenomenon that the theoretical height dimension of the structural components exceeds the detection range of a common height vernier caliper. The traditional structural part processing and mounting mode is as follows: the height dimension is measured by the steel tape, and then the structural parts are knocked up and down by manpower to reach the height dimension measured by the steel tape. However, since the steel tape measure itself has a certain human error, the height and size of the fastened structural member are large, and a series of operations such as repeated disassembly, adjustment and tightening are required to be performed on the structural member. Not only the workload of installation and debugging is increased, but also the task output rate is extremely low.
SUMMERY OF THE UTILITY MODEL
The utility model provides a structure assembly height adjusting device has solved the unable accurate measurement of structure assembly height dimension and has adjusted in the large-scale product effectively, leads to the product once the qualification rate low, problem that production efficiency is low.
In order to achieve the above object, the utility model adopts the following technical scheme:
a structure assembly height adjusting device comprises a bottom plate, a vertical pipe, a welding nut, a lifting bolt and a reference plate;
the vertical pipe is fixed on the bottom plate; the top end of the vertical pipe is provided with a datum plate, and the upper surface of the datum plate is a plane; the side wall of the vertical pipe is fixedly provided with a welding nut, the welding nut is connected with a lifting bolt in an internal thread mode, and the end portion of the lifting bolt abuts against the lower surface of the reference plate.
Preferably, the bottom plate is a flat plate.
Preferably, the vertical pipe is made of hollow square steel and is vertically welded in the center of the upper surface of the bottom plate.
Preferably, the number of the welding nuts is four, and the welding nuts are spot-welded on four corners of the stand pipe.
Preferably, the central hole axis of the weld nut is parallel to the axial direction of the stand pipe.
Preferably, the lifting bolt is provided with scale marks.
Due to the structure, the beneficial effects of the utility model reside in that:
the adjusting device can adjust the heights of the structural members in the same batch in batch, so that the structural members meet the design requirements; and the device has simple structure and convenient operation. The error caused by inaccurate measurement of the machining height when the structural part is measured through the steel tape in the traditional machining and mounting mode is solved, and the production efficiency is greatly improved.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below.
Fig. 1 is a front view of the present invention;
fig. 2 is a top view of the present invention.
Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1 and 2, the present embodiment provides a structural member assembly height adjusting device, which includes a base plate 1, a vertical pipe 2, a weld nut 3, a lifting bolt 4, and a reference plate 5;
the vertical pipe 2 is fixed on the bottom plate 1; a reference plate 5 is arranged at the top end of the vertical pipe 2, and the upper surface of the reference plate 5 is a plane; the side wall of the vertical pipe 2 is fixedly provided with a welding nut 3, the welding nut 3 is internally threaded with a lifting bolt 4, and the end part of the lifting bolt 4 is abutted to the lower surface of the reference plate 5.
In this embodiment, the base plate 1 is a flat plate, and supports the counter tube 2 and the reference plate 5 to ensure the adjustment accuracy of the device.
The vertical pipe 2 is made of hollow square steel and is vertically welded in the center of the upper surface of the bottom plate 1, the length of the vertical pipe is determined according to the theoretical height of structural members of the same batch, in actual operation, the length is generally determined according to the minimum value of the theoretical height of the structural members of the same batch, and the installation height of the structural members of the same batch is not greatly different, so that the height of the structural members can be finely adjusted on the basis of the height of the vertical pipe through the matching of the upgrading bolt 4 and the welding nut 3, the design requirements are met, and the vertical pipe 2 mainly plays a role in bearing the reference plate 5 in the.
The number of the weld nuts 3 is not limited to four, and three or more weld nuts 3 may be provided, and the upper surface of the reference plate 5 can be adjusted to a horizontal surface while adjusting the height by providing three weld nuts 3 according to the principle that three points define one surface.
In this embodiment, the lifting bolt 4 is provided with scale marks, and the lifting bolt 4 is not directly connected with other parts of the device, and is only used in cooperation with the welding nut 3 to finely adjust the height.
It should be noted that, no scale mark may be provided on the lifting bolt 4, and since the size of each thread of the bolt is the same, the height of the lifting bolt 4 may be determined according to the number of threads of the bolt out of the nut.
The reference plate 5 is also not connected to the rest of the device, in which it is mainly used as a reference for the fine-tuned measurement.
The working process principle of the structure is as follows:
when the structural member is assembled, firstly, the bottom plate 1, the vertical pipe 2 and the welding nut 3 are welded, and the reference plate 5 is arranged on the welding nut 3; and then placing the device on the lower end face of the structural part, adjusting the theoretical height dimension of the structural part by screwing or unscrewing the lifting bolt 4 so as to meet the design requirement, tightening the structural part after fine adjustment is completed, and removing the device.
The adjusting device can adjust the heights of the structural members in the same batch in batch, so that the structural members meet the design requirements; and the device has simple structure and convenient operation. The error caused by inaccurate measurement of the machining height when the structural part is measured through the steel tape in the traditional machining and mounting mode is solved, the one-time qualification rate of the product is greatly improved, and the production efficiency is further improved.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
