Abstract
The utility model relates to a fixture for testing compression resistance of cement, which is used for testing the compression resistance intensity of cement. The utility model adopts a structure of directional slot movable panel and a positioning pin is arranged on a frame, which benefits for the production and assembly of fixtures for testing compression resistance of cement which fully meet the national standard, lowers the rejection rate and benefits for the production and users' tests.
Description
A kind of cement resistance to compression anchor clamps belong to the cement performance appliance, are used to check the compressive strength of cement, are applicable to cement production enterprise, build Ministry of worker's door, universities and colleges, the relevant quality testing department with each of R﹠D institution.
Cement resistance to compression anchor clamps are placed on pressure test aircraft measurements strength of cement and use, and its structure mainly adopts framework and last lower platen, and by the pressurization of pressure transmission post, its top board has the sphere of protrusion, and the pressure transmission cornice has recessed sphere.For accurately determining the compression strength value of cement, just require the coaxiality deviation of cement resistance to compression anchor clamps little, the size of pressing plate is accurate, the displacement degree of last lower platen is little, thereby make the pressure surface that adds of test block be subjected to vertical force even, and make the size of compression face accurate, the register pin of original cement resistance to compression anchor clamps is to be contained on the lower platen, guide slot is directly groove milling on framework, inconvenience solves processing technology and assembles the deviation of bringing like this, original cement resistance to compression anchor clamps are owing to adopt fixing register pin and guide slot, make once machining deviation occurs, these anchor clamps will subscription rate, and check can only be seen its average strength and the method for the coefficient of variation quality of differentiating anchor clamps with actual glue sand test, waste greatlyyer, improved cost.
The purpose of this utility model just provides a kind of cement resistance to compression anchor clamps that improve structure, so that can produce qualified cement resistance to compression anchor clamps, the rate of reducing the number of rejects and seconds of assembling out easily.
The utility model by pressure transmission post 1, friction copper sheathing 2, hang spring adjustment joint screw 3, hang spring setting nut 4, hang spring 5, revoke 6, directed pin 7, top board 8, lower platen 9, register pin 10, framework 11, surely follow closely 12, guide slot 13, trip bolt 14 etc. partly form, it is characterized in that: register pin 10 is installed on the framework 11, and guide slot 13 has adopted movable plate structure.
Below in conjunction with accompanying drawing the utility model is described:
Fig. 1 is the cut-open view of the cement resistance to compression anchor clamps in the utility model, its principal feature is the position of having improved register pin 10, it is contained on the framework 11, after adjusting, locate during assembling, guide slot 13 has adopted movable plate structure, locate according to orientation pin 7 during assembling, tighten trip bolt 14 after locating, and it is fixing to add steady nail 12, so just guaranteed the depth of parallelism of last lower platen, accurate position by register pin 10 can make test block concentric with the ball seat of top board, and goes up the lower platen symmetry, thereby helps producing the high grade cement resistance to compression anchor clamps that meet national standard.Fig. 2 is the cut-open view of former cement resistance to compression anchor clamps, because its structural defective makes that the anchor clamps of producing are not easy to detect, its part critical piece can only cause waste as waste product when the anchor clamps of making were defective.
Because the register pin 10 of the cement resistance to compression anchor clamps in the utility model is to be contained on the framework 11, guide slot 13 has adopted movable plate, therefore be convenient to produce and assemble out the cement resistance to compression anchor clamps that meet GB fully, reduced rejection rate, and removed the comparison and detection test that utilizes actual cement briquette from, reduced cost.
