Description

Technical Field

[0001] The utility model relates to the technical field of clamping tools, in particular to a precise and fast centering clamping tool. Background Art

[0002] The screw holding force of artificial boards is one of the important reference indicators for evaluating the mechanical properties of boards. Simply put, it is to test whether the board and the connecting parts are firm. It is related to whether the nails are easy to fix the nail holes after being screwed into the board, and whether they are easy to loosen and fall off. The measurement principle is to determine the force required to pull out the self-tapping screws that are screwed into the specified depth, including the screw holding force of the board surface and the screw holding force of the board edge. However, the screw holding force of the board edge is not measured when the thickness of the specimen is less than 15mm. In the national standard GB / T17657-2022 "Test Methods for Physical and Chemical Properties of Artificial Boards and Faced Artificial Boards", 4.21 Screw Holding Force Determination clearly stipulates that the board surface screw holding force and the board edge screw holding force are tested at the center point of the specimen surface and the center point of the board edge respectively. Secondly, the surface bonding strength of the bonding quality between the surface finishing material of the board and the surface shavings or fibers of the substrate is evaluated. The test operation method also clearly requires that the position of the annular groove needs to be in the center of the specimen.

[0003] At present, in the preparation of test samples for the above experimental projects, the drilling operation for the center point of the screw holding force test piece or the central groove preparation operation for the surface bonding strength test piece is still done by diagonal marking, and then the approximate position of the test piece is adjusted by hand. The preliminary processing of this process is complicated and time-consuming, and the single repetitive operation can easily make the sample preparation personnel feel irritated and tired. The center position of the surface bonding strength test piece is more dependent on long-term operating experience and visual feeling. The center position of the actual sample preparation deviates greatly from the theoretical center position of the test piece in the standard test method. In addition, the sample preparation of similar operations uses sharp tools such as milling cutters and drill bits without safety protection, which poses certain safety hazards.

[0004] Therefore, there is an urgent need to provide a precise and fast centering clamping tool to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the shortcomings of the above-mentioned prior art and provide a precise and fast centering clamping tool.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a precise and fast centering clamping tool, including an operating slide, a cross-connecting component is fixedly connected to the bottom of the operating slide, a fixed support seat is fixedly connected to the top of the cross-connecting component, and a base is fixedly connected to the bottom of the cross-connecting component;

[0007] A Y-axis direction positioning pull rod component is installed on the top of the fixed support seat, and two bearing embedded components are fixedly connected on both sides of the X-axis direction of the bottom of the operating slide, and an X-axis direction positioning mechanism is installed on the outer wall of the bearing embedded component.

[0008] The utility model is further configured as follows: the Y-axis direction positioning pull rod component includes a smooth metal rod movably connected to the inside of a fixed support seat, a pulling handle at the front end of the smooth metal rod in the Y-axis direction, a limiting metal spring is provided on the outer wall of the smooth metal rod, a first positioning block is fixedly connected to the top of the front end in the Y-axis direction of the operating slide, two guide rails are provided on the top of the operating slide, one of the guide rails is slidably connected to a limiting slider, two nylon ropes are fixedly connected to the rear end in the Y-axis direction of the limiting slider, two directional pulleys are rotatably connected to the top of the operating slide, the other ends of the two nylon ropes are fixedly connected to a second positioning block, one end of the limiting metal spring is fixedly connected to the fixed support seat, and the other end of the limiting metal spring is fixedly connected to the second positioning block, the outer walls of the two nylon ropes are respectively rotatably connected to the corresponding directional pulleys, and the fixed support seat is located between the cross-connecting component and the operating slide.

[0009] Through the above technical solution, when the tooling is in use, when the tooling is in a non-working state, the original length of the limiting metal spring on the smooth metal rod is just enough to adjust the contact surface of the first positioning block and the second positioning block to be parallel to the center line in the center of the X-axis direction, and the distance between the first positioning block and the second positioning block is much smaller than the required positioning test piece size. When the tooling needs to be in a working state, by pulling the pulling handle to apply a pulling force, the first positioning block and the second positioning block can move synchronously in opposite directions. After releasing the applied external force, the block gently squeezes the sample toward the center line under the action of the elastic force of the limiting metal spring, so that the center line position of the test block in the X-axis direction is always maintained at the center line position, thereby ensuring the center position of the test block and improving the use effect of the clamping tooling.

[0010] The utility model is further configured as follows: the X-axis positioning mechanism includes a threaded reversely symmetrical screw rotatably connected to the inside of a bearing embedded component, a knob end is fixedly connected to one side of the threaded reversely symmetrical screw in the Y-axis direction, a fixed connecting piece is fixedly connected to the bottom of the operating slide, a first clamping baffle is slidably connected to the inside of the guide rail, a second clamping baffle is slidably connected to the inside of the guide rail, the bottom of the fixed connecting piece is fixedly connected to the cross-connecting component, and the first clamping baffle and the second clamping baffle are rotatably connected to the threaded reversely symmetrical screw through a reverse ball screw of a ball bearing combination.

[0011] Through the above technical solution, the X-axis direction positioning mechanism not only realizes that the center line position of the test sample in the Y-axis direction always coincides with the center line of the positioning device, but also needs to realize the fastening and clamping of the test sample. Therefore, the X-axis direction slider module uses a double-threaded ball screw in combination with an alloy guide rail. The screw is rotated by the knob end, and the first clamping baffle and the second clamping baffle can move synchronously in opposite directions to realize the positioning of the center line of the sample. Since the fixture is fixed under the bench drill by the base, and the clamping center of the fixture is completely coincident with the working center of the bench drill, The intersection of the center lines of the X-axis screw module and the Y-axis spring module of the fixture is the center point of the fixture. When the X-axis screw module and the Y-axis spring module are in the clamping working state, the intersection of the center lines of the specimen in the X-axis and Y-axis directions is the center point of the specimen, and in this state, the clamping center of the fixture and the center of the specimen are on the same vertical line. Therefore, during the sample preparation operation, you only need to put the specimen that meets the standard size range on the operating slide, shake the handle to adjust the X-axis screw slider to clamp the specimen, and then you can directly drill or mill grooves on the specimen.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. The utility model designs a simple Y-axis positioning rod component and an X-axis positioning mechanism. When the centering clamping fixture is put into use, a simple structure is adopted to make it convenient to use, the centering accuracy is high, the measured experimental results are more scientific and accurate, and the sample processing time before the experiment is shortened. Secondly, the fixture reduces the dependence of similar sample processing experimental projects on technically experienced personnel.

[0014] 2. The utility model cooperates with the Y-axis positioning rod component and the X-axis positioning mechanism in use, and can be adapted to other experimental projects such as surface wear resistance, surface scratch resistance, etc. that require the centering position of the sample to be processed while using the tooling, thereby improving the efficient use of laboratory resource allocation.

The first and second positioning blocks 504 and 509 are connected to the first and second positioning blocks 504 and 509 respectively. The first and second positioning blocks 504 and 509 are connected to the first and second positioning blocks 504 and 509 respectively. The first and second positioning blocks 504 and 509 are connected to the first and second positioning blocks 504 and 509 respectively. The first and second positioning blocks 504 and 509 are connected to the second and second positioning blocks 509 ... can move in opposite directions synchronously by pulling the tension handle 502 to apply tension. After releasing the applied external force, the block gently squeezes the sample toward the center line under the elastic force of the limit metal spring 503, thereby achieving that the center line position of the test block in the X-axis direction is always kept at the center line position, thereby ensuring the center position of the test block and improving the use effect of the clamping tooling;

[0024] like Figure 1 and Figure 6As shown, two bearing embedded parts 6 are fixedly connected on both sides of the bottom of the operating slide 1 in the X-axis direction, and an X-axis direction positioning mechanism 7 is installed on the outer wall of the bearing embedded part 6. The X-axis direction positioning mechanism 7 includes a threaded reverse symmetrical screw 701 rotatably connected to the inside of the bearing embedded part 6, and a knob end 702 is fixedly connected to one side of the threaded reverse symmetrical screw 701 in the Y-axis direction. A fixed connector 703 is fixedly connected to the bottom of the operating slide 1, a first clamping baffle 704 is slidably connected to the inside of the guide rail 505, and a second clamping baffle 705 is slidably connected to the inside of the guide rail 505.

In addition to realizing that the center line position of the test sample in the Y-axis direction always coincides with the center line of the positioning device, the X-axis direction positioning mechanism 7 also needs to realize the fastening and clamping of the test sample.

After the applied external force is released, the block gently squeezes the sample toward the center line under the elastic force of the limiting metal spring 503, and then the screw is rotated by the knob end 702, and the first clamping baffle 704 and the second clamping baffle 705 can move in opposite directions synchronously to realize the positioning of the center line of the sample, thereby completing the working process of the entire centering clamping tooling.
