Abstract
The utility model discloses a checking tool reference protection device. The checking tool reference protection device comprises a protection cover and a base. The protection cover has an inverted barrel-shaped structure which is made from a steel plate through the punch forming process, and the outer side surface of the open end of the protection cover is provided with threads. The base has a sheet-like structure, an A screw hole adapting to the threads is formed in the middle portion of the base, at least two B screw holes are vertically formed in the outside of the A screw hole, and bolts are screwed into the B screw holes to fasten the base. The checking tool reference protection device not only can be used to prevent dust, and but also can be used to protect the checking tool reference from being damaged, the assembly and disassembly work of the protection cover can be completed directly by hands through the turning operaiton without using other tools, so advantages of simple structure, easy operation and greatly-improved assembly and disassembly working efficiency can be realized.
Description
Technical field
The utility model relates to the automobile gauge field, is specifically related to a kind of cubing benchmark protective device.
Background technology
At automobile manufacturing field, the precision of cubing is determining the precision of auto parts and components and even car load.And the cubing benchmark is to utilize three coordinate measuring machine to demarcate the device that the cubing precision is set up coordinate system, and its precision is directly determining again the cubing precision, so the accuracy requirement of cubing benchmark is very high, it is protected also very important.At present, known cubing benchmark protective device has two classes: a class adopts plastics or rubber to make, and is frangible yielding when this class cubing benchmark protective device is subject to external force, can only prevent dust, and can not protect the cubing benchmark that it is avoided impaired; Also have a class to adopt metal material to make, though can avoid the cubing benchmark impaired, all need wear the operations such as trip bolt, pin when installing at every turn, time and effort consuming not only, pretty troublesome during dismounting, operation field may not have suitable screwdriver or spanner sometimes yet, installs, dismantles especially difficulty.
The utility model content
For solving the problems of the technologies described above, we have proposed a kind of cubing benchmark protective device, can prevent dust, and can protect the cubing benchmark that it is avoided again impaired, and installation, disassembling section are convenient, and are laborsaving during joint.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of cubing benchmark protective device comprises protective cover and base; Described protective cover is the barrel shaped structure that steel plate punched moulding back-off is placed, and its opening end lateral surface is provided with screw thread; Described base is schistose texture, its middle part offer one with the suitable A screw of described screw thread, the described A screw outside vertically offers at least 2 B screws, and screws in the described B screw described base is fastening by bolt.
Preferably, described cubing benchmark protective device comprises that also two ends are connected to the web member of described protective cover and described base.
Preferably, described web member is wire rope.
Pass through technique scheme; use cubing benchmark protective device of the present utility model; both can prevent dust; can protect the cubing benchmark that it is avoided again impaired; and do not need by other instruments, directly with moving installation, the dismantlement work that just can finish described protective cover of hand-screw, simple in structure; easy to operate, greatly improved the work efficiency of installation, dismounting.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is an embodiment accompanying drawing of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.

3. wire rope
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtain under the creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with embodiment and embodiment the utility model is described in further detail.
Embodiment.
Such as Fig. 1, Fig. 2 and shown in Figure 3, a kind of cubing benchmark protective device comprises protective cover 1 and base 2; Protective cover 1 is the barrel shaped structure that steel plate punched moulding back-off is placed, and its opening end lateral surface is provided with screw thread 11; Base 2 is schistose texture, its middle part offer one with the suitable A screw 21 of screw thread 11, described A screw 21 outsides vertically offer at least 2 B screws 22, and it is interior fastening with described base 2 to screw in described B screw 22 by bolt.
This cubing benchmark protective device comprises that also two ends are connected to the wire rope 3 of protective cover 1 and base 2.
Install for the first time, when dismantling, can carry out as follows:
Step 1: first the cubing benchmark on the cubing is placed A screw 21, then base 2 is fastened on the cubing by B screw 22 with screw.
Step 2: protective cover 1 is enclosed within on the cubing benchmark, screw thread 11 is placed on the A screw 21 again, protective cover 1 is tightened in turn, and it is fastened on the base 2.During dismounting, convolution protective cover 1 makes it break away from base 2 and gets final product.
The second time and later installation, dismounting, the operation of installation steps two gets final product only to need to repeat for the first time.
As can be seen from the above embodiments; adopt cubing benchmark protective device of the present utility model both can prevent dust; can protect the cubing benchmark that it is avoided again impaired; and do not need by other instruments; directly with moving installation, the dismantlement work that just can finish protective cover 1 of hand-screw; laborsaving during joint, greatly improved the work efficiency of installation, dismounting.
Above-described only is a kind of cubing benchmark protective device preferred implementation of the present utility model; should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
