Description

Technical Field

[0001] This utility model relates to the technical field of nickel release wear testers, specifically a nickel release test wear tester. Background Technology

[0002] The nickel release wear tester is an instrument that uses accelerated wear to extract substances for testing metal content. This method is used to detect the release of nickel from coatings that come into direct contact with the skin or extend into contact with the skin. It can also be used to detect other metallic substances.

[0003] Although existing nickel-releasing abrasion testers can detect objects, there is a problem that when these testers are in operation, the object rolls synchronously with the abrasive inside the tester's barrel as it is driven. During this movement, the object may collide with other materials, causing additional damage and affecting the accuracy of subsequent wear detection.

[0004] A search revealed a high-performance nickel release wear tester in patent document CN216560118U. This tester utilizes a fixed mechanism where a handle rotates, causing a first screw to rotate. This rotation of the first screw moves a first threaded sleeve left and right, which in turn moves two connecting rods synchronously. The rotation of these connecting rods then causes two cranks to open and close, clamping and fixing objects inside the cylinder for suspension. This restricts the movement of the objects and effectively prevents them from rotating synchronously with the cylinder, causing collisions and additional damage that could affect the accuracy of subsequent wear detection, thus improving overall detection accuracy.

[0005] While the existing technology can clamp and fix objects and rotate them synchronously to avoid collisions, it can only clamp and fix one object at a time and cannot perform nickel release testing and wear detection on multiple objects simultaneously. Therefore, a new nickel release testing wear meter is proposed to optimize the existing technology. Utility Model Content

[0006] The purpose of this invention is to provide a nickel release test wear instrument to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A nickel release wear tester includes a mounting ring, within which a cylinder adapted to the mounting ring is rotatably mounted. The cylinder's open end is fitted with a matching lid, which is bolted to the cylinder. Fixing blocks for bolt installation are fixedly connected to both the lid and the cylinder. The fixing blocks on the lid have circular holes for bolt penetration, and the fixing blocks on the cylinder have threaded holes for bolt threading. Guide ribs are provided on the inner circumference of the cylinder. Multiple mutually fitting fixing frames are provided inside the cylinder. Each fixing frame has a guide groove corresponding to the guide ribs. An L-shaped clamp is fixedly connected to the inner side of each fixing frame. Symmetrical and fitting L-shaped clamps are provided on both sides of the L-shaped clamp, and the L-shaped clamps are fixed together. A threaded shank is threaded through the fixing frame at the corresponding L-shaped clamp. The threaded end of the threaded shank is inserted into the fixing frame and rotatably mounted at the connection point with the L-shaped clamp.

[0009] As a further embodiment of this utility model: the fixing frame is slidably connected to the guide rib through the guide groove, one of the fixing frames abuts against the inner wall of the bottom of the cylinder, and the other fixing frame abuts against the inner wall of the lid.

[0010] As a further improvement of this utility model, both the clamping surface of the L-shaped clamp and the clamping surface of the L-shaped clamp are uniformly and fixedly connected with pads.

[0011] As a further embodiment of this utility model: a U-shaped frame is fixedly connected to the bottom end of the cylinder corresponding to the mounting ring, a motor is fixedly installed on the U-shaped frame, the output end of the motor is fixedly installed to the bottom end of the cylinder, and the motor is externally connected to a power supply and a switch.

[0012] As a further embodiment of this utility model: a support seat is provided on the outer side of the mounting ring, and the top surface of the support seat rotates with the mounting ring via a pin. The pin rotates through the support seat and is fixedly connected to the mounting ring. An extension arm is fixedly connected to the end of the pin, and a threaded knob is threadedly connected to the end of the extension arm. A threaded hole for threaded connection of the threaded knob is provided on the extension arm.

[0013] As a further embodiment of this utility model: the threaded end of the threaded knob is inserted into the support base, and the support base has two insertion holes for inserting the threaded end of the threaded knob, the two insertion holes being set at 90° relative to the pin shaft.

[0014] As a further embodiment of this utility model: the upper side wall of the cylinder is fixedly connected with a stop ear that corresponds to and is adapted to the support seat, and the stop ear abuts against the support seat after the cylinder rotates 90°.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The present invention uses a threaded shank to drive an L-shaped chuck to move relative to an L-shaped clamping seat within the fixing frame, thereby clamping and fixing the object to be tested for nickel release wear. The fixing frame can be stacked inside the cylinder and is constrained by the cylinder and the lid. At the same time, the fixing frame can form a rotation constraint through the cooperation of guide grooves and guide ribs, thus confining the object to be tested for nickel release wear inside the cylinder and rotating with the cylinder, avoiding collisions that could cause additional damage and affect the accuracy of subsequent wear detection of the object.

[0017] 2. The fixing frame of this utility model can be stacked and placed inside the cylinder and limited by the cylinder and the lid. At the same time, the fixing frame can form a rotation limit through the cooperation of the guide groove and the guide rib. Thus, multiple fixing frames can be used to fix multiple objects that need to be tested for nickel release wear, which is convenient for simultaneous nickel release wear testing on multiple objects.

[0018] 3. By setting up the pads, this utility model can reduce the contact area between the L-shaped clamp and the L-shaped clamp and the object being tested for nickel release wear, thus avoiding large-area obstruction of the surface of the object being tested for nickel release wear and affecting wear.

[0019] 4. This utility model supports the mounting ring with a support base and achieves 90° rotation of the cylinder by rotating the extension arm and fixing it with a threaded knob. This allows for convenient loading of the mounting frame, grinding pulp, and abrasive when the cylinder is upright, and also facilitates contact between the grinding pulp, abrasive, and workpiece during horizontal rotation operations.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 In this embodiment of the present invention, a nickel release test wear tester includes a mounting ring 1, a cylinder 2 adapted to the mounting ring 1 is rotatably mounted inside the mounting ring 1, a barrel cover 3 adapted to the cylinder 2 is provided at the open end of the cylinder 2, the barrel cover 3 is assembled to the cylinder 2 by bolts, fixing blocks for bolt installation are fixedly connected to the barrel cover 3 and the cylinder 2 respectively, the fixing blocks on the barrel cover 3 are provided with round holes for bolts to pass through, the fixing blocks on the cylinder 2 are provided with threaded holes for bolt thread connection, the inner circumference of the cylinder 2 is provided with guide ribs 4, and multiple mutually fitting fixing frames 5 are provided inside the cylinder 2, each fixing frame 5 is provided with a guide groove 6 corresponding to the guide ribs 4, an L-shaped clamp 7 is fixedly connected to the inner side of the fixing frame 5, and L-shaped clamps 8 are provided on both sides of the L-shaped clamp 7 and are symmetrical and fitted to it, the L-shaped clamps 8 are fixed to each other, and a threaded rotating handle 9 is threadedly connected to the fixing frame 5 corresponding to the L-shaped clamp 8, the threaded end of the threaded rotating handle 9 is inserted into the fixing frame 5 and rotatably mounted at the connection with the L-shaped clamp 8.

[0028] The fixing bracket 5 is slidably connected to the guide rib 4 through the guide groove 6. One of the fixing brackets 5 abuts against the inner wall of the bottom of the cylinder 2, and the other fixing bracket 5 abuts against the inner wall of the lid 3.

[0029] The L-shaped chuck 8 is driven to move relative to the L-shaped clamp 7 through the threaded handle 9 within the fixing frame 5, thereby clamping and fixing the object to be tested for nickel release wear. The fixing frame 5 can be stacked inside the cylinder 2 and is limited by the cylinder 2 and the lid 3. At the same time, the fixing frame 5 can form a rotation limit through the cooperation of the guide groove 6 and the guide rib 4, thus limiting the object to be tested for nickel release wear to be confined inside the cylinder 2 and rotating with the cylinder 2, avoiding collisions that could cause additional damage and affect the accuracy of subsequent wear detection of the object.

[0030] The fixing frame 5 can be stacked inside the cylinder 2 and is limited by the cylinder 2 and the lid 3. At the same time, the fixing frame 5 can be rotated by the cooperation of the guide groove 6 and the guide rib 4. Thus, multiple fixing frames 5 can be used to fix multiple objects that need to be tested for nickel release wear, which is convenient for simultaneous nickel release wear testing of multiple objects.

[0031] Both the clamping surfaces of the L-shaped clamp 7 and the L-shaped chuck 8 are uniformly and fixedly connected with pads 10.

[0032] By setting the pad 10, the contact area between the L-shaped clamp 7 and the L-shaped chuck 8 and the object worn during the nickel release test can be reduced, thus avoiding large-area obstruction of the surface of the object worn during the nickel release test and affecting the wear.

[0033] A U-shaped frame 11 is fixedly connected to the bottom end of the cylinder 2 corresponding to the mounting ring 1. A motor 12 is fixedly installed on the U-shaped frame 11. The output end of the motor 12 is fixedly installed to the bottom end of the cylinder 2. The motor 12 is externally connected to a power supply and a switch.

[0034] The cylinder 2 is driven by motor 12 to rotate within the mounting ring 1, thereby enabling the detection of wear on the surface of the object by the grinding slurry and abrasive.

[0035] A support seat 13 is provided on the outer side of the mounting ring 1. The top surface of the support seat 13 is rotated with the mounting ring 1 via a pin. The pin rotates through the support seat 13 and is fixedly connected to the mounting ring 1. An extension arm 14 is fixedly connected to the end of the pin. A threaded knob 15 is threadedly connected to the end of the extension arm 14. A threaded hole for threaded connection of the threaded knob 15 is provided on the extension arm 14.

[0036] The threaded end of the threaded knob 15 is inserted into the support base 13. The support base 13 has two insertion holes 16 for inserting the threaded end of the threaded knob 15. The two insertion holes 16 are set at 90° relative to the pin.

[0037] The upper side wall of the cylinder 2 is fixedly connected with a baffle 17 that corresponds to and is adapted to the support base 13. After the cylinder 2 rotates 90°, the baffle 17 abuts against the support base 13. The baffle 17 can play an auxiliary support role.

[0038] The mounting ring 1 is supported by the support base 13, and the extension arm 14 is rotated. Combined with the fixing of the threaded knob 15, this allows for a 90° rotation of the cylinder 2. This facilitates the insertion of the mounting bracket 5, grinding pulp, and abrasive when the cylinder is upright, and also allows for convenient contact between the grinding pulp, abrasive, and workpiece during horizontal rotation.

[0039] The working principle of this utility model is as follows:

[0040] In use, place the object to be tested inside the mounting bracket 5 and ensure it is flush with the L-shaped clamp 7. Then, rotate the threaded handle 9. The threaded handle 9 causes the L-shaped chuck 8 to press against the object, forming a clamping effect with the L-shaped clamp 7, thus securing the object. Next, place the mounting bracket 5 inside the cylinder 2, with the guide groove 6 sliding on the outside of the guide rib 4, until the mounting bracket 5 is fully stacked. Then, add the grinding slurry and abrasive into the cylinder 2. Secure the lid 3. Finally, loosen the threaded knob 15 to tilt the cylinder 2. Until the lug 17 abuts against the support base 13, the extension arm 14 is fixed by rotating the threaded knob 15 into the corresponding insertion hole 16, thereby fixing the mounting ring 1 relative to the support base 13 and maintaining the lateral state of the cylinder 2. At this time, the motor 12 is started, and the motor 12 drives the cylinder 2 to rotate within the mounting ring 1. This allows the grinding slurry and abrasive to repeatedly contact the object for wear detection. During the detection, the object is fixed within the fixing frame 5, effectively preventing the object from colliding with the inside of the cylinder 2.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
