Description

Technical Field

[0001] The utility model relates to the technical field of denture processing and detection, and particularly relates to a denture surface performance detection device. Background Art

[0002] Dentures, commonly known as "false teeth", refer to teeth that "fulfill their obligations" for humans. Medically, they are the general term for prostheses made after partial or complete loss of upper and lower teeth. Dentures are divided into removable and fixed types. Fixed dentures cannot be taken off or put on by the patient himself, while removable dentures can be conveniently taken off and put on by the patient. In the research on parameter comparison of denture processing process or processing materials, it is necessary to detect the surface performance of dentures. For example, after rubbing the outer periphery of the denture and then taking pictures for comparison or weighing, the wear resistance of the denture can be evaluated according to parameters such as its texture or weight. However, the existing detection devices generally only apply to manual single measurement. It is necessary to wait until the measurement is completed, then take out the denture and put in a new one. The operation is cumbersome and not convenient for large-scale measurement work. Content of the Utility Model

[0017] Furthermore, the detection component includes a photographing member for photographing and recording the surface image of the friction surface of the denture after friction.

[0018] By adopting the above technical solution, the photographing member photographs and records the surface image of the friction surface of the denture after friction to judge its wear resistance according to its wear condition, which is convenient for magnified observation and also convenient for future automated vision detection work.

Detailed Embodiment

[0028] The following further describes the specific embodiments of the present utility model with reference to the drawings. This embodiment does not constitute a limitation to the present utility model. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of this application.

[0029] A denture surface performance detection device, as Figure 1 shown, includes a workbench 1. The workbench 1 is provided with a feeding port 2 and a discharging port 3. Lifting components are provided in both the feeding port 2 and the discharging port 3. The lifting components are used to lift the stacked clamping plates 4. One or more dentures are clamped and fixed in the clamping plates 4. The lifting components drive the clamping plates 4 to rise or fall by the thickness distance of one clamping plate 4 each time, realizing the automatic loading and unloading of the clamping plates 4.

[0030] Among them, as Figure 2As shown in the figure, the clamping disc 4 is provided with two pressing plates 41, several guide rods, and a screw rod 42 for driving the two pressing plates 41 to approach or move away from each other. The clamping disc 4 is also fixed with guide rods or guide rails that are parallel to each other. The guide rods penetrate through the two pressing plates 41 to guide their movement of approaching or moving away from each other, so that the two pressing plates 41 move away from or approach each other along the guide rods or guide rails;

[0031] The denture is clamped between the two pressing plates 41. The screw rod 42 is rotatably connected to the clamping disc 4, and the outer end is connected to a hand-tightening head for convenient hand-tightening. Two threads with opposite helix directions are machined on the screw rod 42, which are respectively threadedly connected to the two pressing plates 41. When the screw rod 42 rotates, the two pressing plates 41 approach or move away from each other. One side of the pressing plate 41 that approaches each other can be connected to a lining plate by screws. The outer side of the lining plate is set to a shape adapted to the corresponding side surface of the corresponding denture to better fix one or more dentures.

[0032] As Figure 3 shown in the figure, the lifting assembly includes a lifting table 5, multiple guide rods, and a lead screw 51 for driving the lifting of the lifting table 5. The guide rods penetrate through the lifting table 5 to realize its up and down guiding. The lead screw 51 is driven by a motor to rotate to realize the lifting of the clamping disc 4, so as to control the clamping disc 4 to move upward for continuous feeding, or move downward for discharging;

[0033] Limit cylinders 6 are fixed below the feeding port 2 and the discharging port 3. The size of the limit cylinder 6 is adapted to the clamping disc 4; one side of the limit cylinder 6 is open. One side of the lifting table 5 is located inside the limit cylinder 6, and the other side leaves the limit cylinder 6 from the opening and is connected to the lead screw 51. A detection door body is opened on the other side of the limit cylinder 6 to facilitate opening and closing for maintenance and repair.

[0034] As Figure 1 shown in the figure, a driving member is provided on the workbench 1. The driving member drives the clamping disc 4 in the feeding port 2 to move to the discharging port 3, and the moving path also passes through the testing assembly 9 and the surface detection assembly 10. A friction-reducing structure such as a ball can be embedded at the bottom of the clamping disc 4 to facilitate movement;

[0035] Among them, the driving member includes several rotating arms 7. The middle of the rotating arm 7 is connected to the central axis, and the central axis is driven to rotate by a driving device such as a motor; baffles can be connected between adjacent rotating arms 7 to be combined into a circular plate to block above the workbench 1 to reduce dust falling; the outer end of the rotating arm 7 is connected to a sleeve 71. The sleeve 71 is vertically penetrated and sleeved outside the corresponding clamping disc 4. While not affecting the loading and unloading of the clamping disc 4, it can push the corresponding clamping disc 4 to move on the workbench 1 so that it can flow through different testing or detection stations;

[0036] In order to limit the position of the swing arm 7 after rotation and improve the stability of the position of the clamping disk 4 during testing, a cylinder can be connected to the workbench 1. The output end of the cylinder is connected upward to a limit insertion block 8. A limit hole 72 adapted to the limit insertion block is provided on the lower side of the swing arm 7. After each rotation of the swing arm 7, the limit insertion block 8 is inserted into the limit hole 72 of the corresponding swing arm 7.

[0037] The test assembly 9 includes a friction head for friction on the surface of the denture or a spray head for spraying a fluid containing friction particles. The surface of the denture is friction-tested through the friction head or the fluid containing friction particles to compare or detect the surface wear resistance of the denture, etc., so as to achieve the test. The friction head can be driven to lift or traverse linearly to perform friction tests on the upper or side of the denture. The test assembly can also be connected downward to a dust-proof cylinder, which abuts above the clamping disk 4 to reduce dust, etc.

[0038] The detection assembly 10 includes a photographing member, which takes pictures to record the surface image of the friction surface of the denture after friction. The photographing member takes pictures to record the surface image of the friction surface of the denture after friction, so as to judge its wear resistance according to its wear condition, which is convenient for magnified observation. It can also be replaced with a visual processing device such as AVI. The test assembly 9 and the detection assembly 10 are prior arts, and their specific structures will not be elaborated here.

[0039] Working principle:

[0040] The lifting assembly at the feed inlet 2 rises by a distance equal to the thickness of a clamping disk 4, jacking up the uppermost clamping disk 4 to a position higher than the tabletop of the workbench 1, and when the uppermost clamping disk 4 is jacked up, it is exactly limited within the corresponding sleeve 71.

[0041] Then the central shaft rotates to drive each swing arm 7 to rotate by 90°. The corresponding sleeve 71 drives the clamping disk 4 to move below the test assembly 9, and the friction head moves into place and performs friction on the surface of the denture.

[0042] After the test time is up, the swing arm 7 continues to rotate by 90°. The corresponding sleeve 71 drives the clamping disk 4 to move below the detection assembly 10, and records the surface image of the friction surface of the denture after friction to evaluate its wear resistance.

[0043] Finally, the swing arm 7 rotates by 90°. The corresponding sleeve 71 drives the clamping disk 4 to move below the discharge port 3, and its lifting assembly descends by a distance equal to the thickness of a clamping disk 4, so that the tested clamping disk 4 descends below the tabletop of the workbench 1; wait for the swing arm 7 to continue to rotate by 90°, and this sleeve 71 returns to the feed inlet 2 to start the next cycle.

[0044] The above are only the preferred embodiments of the present utility model, and are not used to limit the present utility model. Those skilled in the art can make various modifications or equivalent replacements to the present utility model within the essence and protection scope of the present utility model, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the technical solution of the present utility model.
