Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vertically clamping and fixing test pieces, in particular to a clamping tool for test pieces. Background Art
[0002] The function of an ion vacuum coating furnace is to sputter the metal material on the target onto the substrate under appropriate process conditions, so as to form a coating on the surface of the substrate. The functions of the coating are: 1. To increase the antioxidant performance of the substrate. 2. To increase the mechanical strength of the substrate.
[0003] When a batch of saw blades are produced in the workshop, the workers also need to put a batch of saw blades into the ion vacuum coating furnace to coat a layer of coating on the outer surfaces of each saw blade. Before coating, in order to know the thickness of the coating on the surface of the saw blade, the worker needs to place multiple test pieces 1 as shown Figures 1 to 2 vertically in the vacuum coating furnace while placing the saw blades in the ion vacuum coating furnace; after coating, the worker takes out multiple test pieces 1 from the ion vacuum coating, and measures the thickness of the coating on the surface of the test piece 1 with a measuring instrument. This thickness is the thickness of the coating on the surface of the saw blade [because the test piece 1 and the saw blade are sputtered under the same process conditions, so the thickness of the coating on the test piece 1 is equal to the thickness of the coating on the saw blade], and then knows the thickness of the coating on the surface of the saw blade.
[0004] In order to place multiple test pieces 1 vertically in the vacuum coating furnace, a clamping tool as shown Figures 3 to 4 is used to fix multiple test pieces 1 vertically in advance. The clamping tool includes a strip-shaped block 2. A plurality of sinking grooves 3 are arranged at intervals along the length direction on the front end surface of the strip-shaped block 2. A plurality of threaded rods 4 are fixedly arranged on the front end surface of the strip-shaped block 2 and are respectively located directly above the sinking grooves 3. A pressing block 5 is threadedly connected to each threaded rod 4.
[0005] The method for the clamping tool to fix three test pieces 1 vertically is as follows:
[0006] S1. The worker unscrews the pressing block 5 from the threaded rod 4, then the worker takes out three test pieces 1 and respectively inserts the three test pieces 1 into the three sinking grooves 3. As shown Figures 5 to 6 , at this time, the front end parts of the test pieces 1 are all exposed outside the sinking grooves 3;
[0007] S2. The worker sequentially screws the pressing block 5 to make the pressing block 5 move along the threaded rod 4 towards the test piece 1 until the pressing block 5 presses the test piece 1, so that the three test pieces 1 are respectively pressed by the three pressing blocks 5. As shown Figures 7 to 8 , and then the three test pieces 1 are fixed vertically.
[0008] After the three test pieces 1 are fixed upright, the worker puts the clamping tooling and the saw blade into the vacuum coating furnace at the same time. The vacuum coating furnace coats a layer of coating on the outer end faces of the three test pieces 1 and the outer surface of the saw blade. After coating, the worker takes out the clamping tooling and the saw blade from the vacuum coating furnace. After taking out the clamping tooling, the worker loosens the pressing block 5, and then takes out the test piece 1 from the sinking groove 3. The thickness of the coating plated on the surface of the test piece 1 is measured by a measuring instrument, so as to know the thickness of the coating plated on the saw blade.
[0009] However, although this clamping tooling can fix the three test pieces 1 upright, there are still the following technical defects in the actual use process:
[0010] I. In step S2, the worker needs to screw three pressing blocks 5 to press the three test pieces 1 respectively, which undoubtedly increases the time used to fix the test piece 1, and thus reduces the fixing efficiency of the test piece 1.
[0011] II. In step S2, when the test piece 1 is to be taken out from the sinking groove 3, the test piece 1 is still tightly embedded in the sinking groove 3, resulting in the worker needing a lot of strength to pull out the test piece 1 from the sinking groove 3, which undoubtedly increases the working intensity of taking out the test piece 1.
[0012] Therefore, there is an urgent need for a clamping tooling that can greatly improve the fixing efficiency of the test piece and reduce the working intensity of taking out the test piece. Utility Model Content
[0013] The purpose of the present utility model is to overcome the shortcomings of the prior art and provide a clamping tooling for test pieces that can greatly improve the fixing efficiency of the test piece and reduce the working intensity of taking out the test piece.
[0014] The purpose of the present utility model is achieved by the following technical solutions: A clamping tooling for test pieces, which includes a strip-shaped block. Along the length direction of the front end face of the strip-shaped block, a plurality of sinking grooves are spaced apart. A connecting plate is fixedly arranged on the right end face of the strip-shaped block. A base is fixedly arranged on the front end face of the connecting plate. A torsion spring is fixedly arranged on the left end face of the base. The left end of the torsion spring is fixedly provided with a circular plate. A rod rotatably installed on the front end face of the strip-shaped block is welded on the left end face of the circular plate. The rod is located below the sinking groove. A plurality of strip-shaped pressing heads are welded on the top surface of the rod along the length direction of the rod. The strip-shaped pressing heads are located in front of the sinking groove.
[0015] A pushing mechanism is further arranged on the strip-shaped block. The pushing mechanism includes a plurality of through holes opened on the rear end face of the strip-shaped block. The plurality of through holes are respectively communicated with their corresponding sinking grooves. A push rod is slidably installed in each through hole. A push plate is fixedly connected between the rear ends of the push rods. A spring is sleeved on each push rod. One end of the spring is fixedly arranged on the rear end face of the strip-shaped block, and the other end is fixedly arranged on the push plate.
[0016] Two support plates are fixedly arranged on the front end surface of the strip-shaped block. The two support plates are respectively located on the left and right sides of the strip-shaped block, and the left and right ends of the rod member are respectively rotatably installed in the two support plates.
[0017] The torsion spring, the circular plate and the rod member are coaxially arranged.
[0018] The depth of the sinking groove is less than the thickness of the test piece.
[0019] Three sinking grooves are formed on the front end surface of the strip-shaped block, and the distance between every two adjacent sinking grooves is equal.
[0020] The utility model has the following advantages: greatly improving the fixing efficiency of the test piece and reducing the working intensity of taking out the test piece. Description of the Drawings

[0042] The following further describes the present utility model in conjunction with the attached drawings. The protection scope of the present utility model is not limited to the following:
[0043] As Figures 9 to 11 shown, a clamping tool for test pieces includes a strip-shaped block 2. On the front end face of the strip-shaped block 2, a plurality of sinking grooves 3 are spaced apart along its length direction. The depth of the sinking groove 3 is less than the thickness of the test piece 1. Three sinking grooves 3 are provided on the front end face of the strip-shaped block 2, and the distance between every two adjacent sinking grooves 3 is equal. A connecting plate 6 is fixedly arranged on the right end face of the strip-shaped block 2. A base 7 is fixedly arranged on the front end face of the connecting plate 6. A torsion spring 8 is fixedly arranged on the left end face of the base 7. The left end of the torsion spring 8 is fixedly provided with a circular plate 9. A rod 10 rotatably mounted on the front end face of the strip-shaped block 2 is welded on the left end face of the circular plate 9. The rod 10 is located below the sinking groove 3. A plurality of strip-shaped pressing heads 16 are welded on the top surface of the rod 10 along its length direction. The strip-shaped pressing heads 16 are located in front of the sinking groove 3; the torsion spring 8, the circular plate 9 and the rod 10 are coaxially arranged.
[0044] A pushing mechanism is further provided on the strip-shaped block 2. The pushing mechanism includes a plurality of through holes 11 formed in the rear end face of the strip-shaped block 2. The plurality of through holes 11 are respectively communicated with their corresponding sinking grooves 3. A push rod 12 is slidably installed in each through hole 11. A push plate 13 is fixedly connected between the rear ends of the push rods 12. A spring 14 is sleeved on each push rod 12. One end of the spring 14 is fixedly arranged on the rear end face of the strip-shaped block 2, and the other end is fixedly arranged on the push plate 13.
[0045] Two support plates 15 are fixedly arranged on the front end face of the strip-shaped block 2. The two support plates 15 are respectively located on the left and right sides of the strip-shaped block 2. The left and right ends of the rod member 10 are respectively rotatably installed in the two support plates 15.
[0046] The method for a worker to use this clamping tooling to vertically fix three test pieces is as follows:
[0047] S1. The worker takes out three test pieces 1 as Figures 1 to 2 shown;
[0048] S2. The worker manually rotates the rod member 10. The rod member 10 drives all the strip-shaped pressing heads 16 thereon to rotate downward around its own axis. At the same time, the rod member 10 also drives the circular plate 9 to rotate synchronously. The circular plate 9 causes the torsion spring 8 to be distorted. When the strip-shaped pressing head 16 rotates downward by 180°, as Figures 12 to 13 shown, the worker respectively inserts the three test pieces 1 into the three sinking grooves 3, as Figures 14 to 15 shown;
[0049] S3. The worker releases the rod member 10. Under the restoring force of the torsion spring 8, the rod member 10 rotates reversely around its own axis. The rod member 10 drives each strip-shaped pressing head 16 thereon to rotate upward synchronously around its own axis. At this time, the three test pieces 1 are clamped by the corresponding strip-shaped pressing heads 16, as Figures 16 to 17 shown, thereby finally realizing the vertical fixation of the three test pieces 1.
[0050] Among them, it can be seen from steps S2 to S3 that the worker only needs to first rotate the rod member 10 to distort the torsion spring 8, then insert the three test pieces 1 into the three sinking grooves 3 respectively, and then release the rod member 10. Under the restoring force of the torsion spring 8, the rod member 10 drives each strip-shaped pressing head 16 to reset, and then the test piece 1 is clamped by the strip-shaped pressing head 16. It can be seen that compared with the clamping tooling as Figures 3 to 8 shown, this clamping tooling does not require manual screwing of three pressing blocks 5 to press the three test pieces 1 respectively, thus greatly shortening the time for fixing the test piece 1 and further greatly improving the fixing efficiency of the test piece 1.
[0051] After fixing the three test pieces 1 upright, the worker puts the clamping tooling and the saw blade into the vacuum coating furnace at the same time. The vacuum coating furnace coats a layer of coating on the outer end faces of the three test pieces 1 and the outer surface of the saw blade. After coating, the worker takes out the clamping tooling and the saw blade from the vacuum coating furnace.
[0052] After taking out the clamping tooling, the method for the worker to take away the test piece 1 in the sink 3 is as follows:
[0053] S4. The worker manually rotates the rod 10. The rod 10 drives all the strip-shaped pressing heads 16 thereon to rotate downward around its own axis. The strip-shaped pressing heads 16 no longer clamp the test piece 1, and the rod 10 is kept stationary.
[0054] S5. The worker pushes the push plate 13 by hand. The pushing direction is as shown by the hollow arrow in Figure 18 . The push plate 13 compresses the spring 14 and drives each push rod 12 synchronously. The push rod 12 pushes the test piece 1 in the sink 3 forward, so as to take out the test piece 1 in the sink 3. After taking away the test piece 1, the worker measures the thickness of the coating plated on the surface of the test piece 1 through a measuring instrument, and then knows the thickness of the coating plated on the saw blade.
[0055] Among them, from steps S4 to S5, it can be seen that the worker only needs to manually rotate the rod 10 first to separate the strip-shaped pressing heads 16 on the rod 10 from the test piece 1, and then push the push plate 13 forward, so that the push rod 12 can push the test piece 1 forward, and then push out the test pieces 1 in each sink 3 from the sink 3 at one time. It can be seen that this clamping tooling realizes quickly taking out the test piece 1 from the sink 3, and there is no need for the worker to spend a lot of effort to pull out the test piece 1 from the sink 3, thus greatly reducing the working intensity of taking out the test piece 1.
[0056] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
