Abstract
The invention provides a clamping fine adjustment mechanism for a train positioning tool, aims to solve the problem that a workpiece always cannot be well assembled during the conventional pressing and positioning realized only through a cylinder or a hydraulic cylinder, and relates to the field of clamping and positioning tools. The clamping fine adjustment mechanism comprises the hydraulic cylinder fixedly arranged on a support, and is characterized in that the front end of an ejector rod of the hydraulic cylinder is fixedly connected with a pressing block; a manual pressing lead screw is also transversely arranged on the lateral surface of the support; and a pressing block is also fixedly arranged at the upper end of the manual pressing lead screw, and comprises a fixing plate and a wear layer, which are connected through a screw or in a clamping way. The workpiece can be quickly pressed and positioned through the hydraulic cylinder, and can be longitudinally adjusted and further pressed and positioned through the manual pressing lead screw under the condition that the workpiece is not well assembled, so that the assembly accuracy of the pressing and positioning tool can be effectively improved, and the quality of a product can be improved.
Description
Technical field:
The present invention relates to clamping, positioning tool field, relate in particular to a kind of clamping micro-adjusting mechanism of train positioning tool.
Background technology:
In machining and welding procedure; clamping, positioning tool are the key equipments that determines machining accuracy, affects product quality; clamping, positioning tool adopt cylinder or hydraulic cylinder to carry out the fast-holding location more at present; but when larger workpiece is carried out clamping and positioning; depend merely on cylinder or hydraulic cylinder compresses; often can occur assembling situation not in place, thereby cause product size relatively large deviation to occur, product quality is difficult to be guaranteed.
Summary of the invention:
The object of the present invention is to provide a kind of clamping micro-adjusting mechanism of train positioning tool, depend merely on cylinder at present or hydraulic cylinder compresses the location to solve, workpiece assembling problem not in place often can occur.
For achieving the above object, the technical solution used in the present invention is:
A kind of clamping micro-adjusting mechanism of train positioning tool, comprise the hydraulic cylinder that is fixed on the bearing, it is characterized in that: the push rod front end of described hydraulic cylinder is fixedly connected with compact heap, and described bearing side also is horizontally arranged with manual clamping screw, and manually the clamping screw upper end also is fixedly installed compact heap.
Described compact heap comprises fixed head and wearing layer, after the wearing layer wearing and tearing, is convenient to timely replacing, compresses and positioning accuracy to improve.
Described fixed head and wearing layer are connected by screw or engagement connection.
Described hydraulic cylinder connects control valve by hydraulic tube.
The present invention not only can carry out the fast-holding location by hydraulic cylinder, in the situation that the workpiece assembling is not in place, can also vertically regulate and further compress by manual clamping screw and locate, but Effective Raise compresses the assembly precision of positioning tool, improves the quality of products.
Description of drawings:
Fig. 1 is structural representation of the present invention.
1. compact heaps wherein; 2. manual clamping screw; 3. hydraulic cylinder; 4. hydraulic tube; 5. control valve; 6. bearing.
The specific embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram and specific embodiment, further set forth the present invention, but be not to limit protection scope of the present invention.
Please refer to Fig. 1, a kind of clamping micro-adjusting mechanism of train positioning tool, comprise the hydraulic cylinder 3 that is fixed on the bearing 6, the push rod front end of hydraulic cylinder 3 is fixedly connected with compact heap 1, bearing 6 sides also are horizontally arranged with manual clamping screw 2, manually clamping screw 2 upper ends also are fixedly installed compact heap 1, compact heap 1 comprises fixed head and wearing layer, after the wearing layer wearing and tearing, be convenient to timely replacing, compress and positioning accuracy to improve, fixed head and wearing layer are connected by screw or engagement connection, and hydraulic cylinder 3 connects control valve 5 by hydraulic tube 4.
Above demonstration and described basic principle of the present invention, principal character and advantage of the present invention.It only is the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention, and the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
