[0021] The present invention provides the following embodiments Example 1 The embodiment of the present invention provides a measuring and testing device for precision molds, such as Figure 1-Figure 3 As shown, it includes a detection shell 1, a base 2 is fixedly provided at the lower end of the detection shell 1, a cavity 9 is provided inside the detection shell 1 and the base 2, a detection mechanism and a dust removal mechanism are provided at the upper end of the cavity 9, the detection mechanism and the dust removal mechanism are connected to the adjustment mechanism, the left and right ends of the lower side of the cavity 9 are symmetrically connected with sliding grooves 18, the left and right sides of the upper end of the base 2 are symmetrically provided with springs 20, the springs 20 are fixedly connected to the lower end of the base 21, the left and right ends of the base 21 are symmetrically provided with sliding blocks, the sliding blocks are slidably connected to the sliding grooves 18, the left and right sides of the upper end of the base 21 are symmetrically provided with clamping blocks 27, and the front and rear sides of the upper end of the base 21 are symmetrically provided with clamping Holding block 23, sliding hole 28 is penetrated at the front and rear ends of clamping block 1 27, sliding blocks 29 are symmetrically arranged on the front and rear sides of sliding hole 28, and pushing block 26 is correspondingly arranged between the sliding blocks 29 on the front and rear sides, and the pushing block 26 is slidably connected with the through hole, and the through hole is arranged at the end of clamping block 1 27 away from clamping block 2 33, and the pushing block 26 is connected with the driving mechanism, and the driving mechanism is arranged on the lower side of cavity 9, and the sliding block 29 is rotatably connected with the sliding shaft 30, and the sliding shaft 30 is slidably connected with the sliding cavity 31, and a spring 2 32 is fixedly arranged between the sliding cavity 31 and the sliding shaft 30, and the sliding cavity 31 is arranged on the rotating rod 34.

[0022] The beneficial effects of the above technical solution are: The base 21 is used to place the precision mold to be inspected, and then the driving mechanism pushes the pushing block 26 to move. The pushing block 26 first pushes the clamping block 27 to move in the direction of approaching each other, so that the clamping block 27 fixes and clamps the left and right ends of the precision mold to be inspected. When the clamping block 27 moves, it drives the sliding block 29 to move. The sliding block 29 drives the sliding shaft 30 to slide along the sliding cavity 31, and the spring 2 32 is deformed. During the sliding process of the sliding shaft 30 along the sliding cavity 31, the rotating rod 34 rotates, and the rotating rod 34 drives the clamping block 2 33 to move, and the clamping block 2 33 moves in the direction of approaching each other. The clamping block 2 33 fixes and clamps the front and rear ends of the precision mold to be inspected. The setting of the spring 2 32 makes the clamping block 2 33 have a shock-absorbing effect when clamping the precision mold to be inspected. If the clamping block 27 first contacts with the precision mold to be inspected, after the clamping block 27 is squeezed and fixed with the precision mold to be inspected and cannot move, the pushing block 26 and the clamping block 27 are relatively displaced, and the pushing block 26 pushes the sliding block 29 to move in the direction away from each other, and the sliding block 29 drives the rotating rod 34 to continue to rotate, and the rotating rod 34 drives the clamping block 2 33 to continue to move in the direction of approaching each other, ensuring that the rotating rod 34 can fix and clamp the front and rear ends of the precision mold to be inspected. If the clamping block 2 33 first contacts with the precision mold to be inspected, after the clamping block 2 33 and the precision mold to be inspected are squeezed and fixed and cannot move, the sliding block 29 moves in the direction of approaching each other, and the pushing block 26 and the clamping block 27 are relatively displaced. At this time, the rotating rod 34 no longer rotates. The clamping block 1 27 can continue to move in the direction of approaching each other, ensuring that the clamping block 1 27 can fix and clamp the left and right ends of the precision mold to be tested, achieving the purpose that the clamping block 1 27 and the clamping block 2 33 can fix and clamp the left, right, front and rear ends of the precision mold to be tested of different sizes, improving the stability of the fixed clamping of the precision mold to be tested, and solving the problem of driving the two sets of L-shaped fixed plates that are matched to each other to move relative or toward each other through the extension and contraction of the piston rods of the two sets of third electric hydraulic rods, and then fixing and clamping the mold according to the size of the mold, but the L-shaped fixed plate can only move in the left and right directions to fix and clamp the left and right ends of the detection equipment, and the front and rear positions of the L-shaped fixed plates cannot be adjusted according to the front and rear dimensions of the mold, resulting in poor technical problems of fixed clamping stability; After the precision mold to be inspected is clamped and fixed, the adjusting mechanism can drive the inspection mechanism and the dust removal mechanism to move to the corresponding positions of the precision mold to be inspected. The dust removal mechanism is first used to perform dust removal and cleaning steps on the precision mold to be inspected to avoid affecting the subsequent inspection and measurement steps, and then the inspection mechanism is used to perform inspection and measurement steps on the precision mold to be inspected.

[0023] Example 2 On the basis of Example 1, Figure 1-Figure 2As shown, the front end of the detection shell 1 is provided with a placement opening, the cavity 9 is connected to the placement opening, an opening plate 3 is provided corresponding to the placement opening, the upper end of the opening plate 3 is fixedly connected to the rotating shaft 8, and the left and right ends of the rotating shaft 8 are symmetrically provided with fixing blocks 7, and the fixing blocks 7 are fixedly arranged at the front end of the detection shell 1; The dust removal mechanism includes a dust removal box 4, which is connected to the dust removal pipe 6. A power pump 16 is installed at the connection point between the dust removal box 4 and the dust removal pipe 6. An opening 15 is provided at the left end of the detection shell 1. A guide wheel 13 is rotatably provided in the opening 15. The guide wheel 13 contacts the dust removal pipe 6 accordingly. The dust removal pipe 6 passes through the opening 15 into the cavity 9 and contacts the dust collection cover 14. The dust collection cover 14 is correspondingly arranged at the upper end of the base 21. The dust cover 14 is fixedly connected to the electric telescopic rod 12, and the electric telescopic rod 12 is fixedly connected to the threaded block 11; The adjustment mechanism includes a threaded rod 10, a threaded section of the threaded rod 10 is threadedly connected to a threaded block 11 and a threaded block 2 17, the threaded block 11 and the threaded block 2 17 are both slidably connected to the upper end of the cavity 9, the threaded block 11 is fixedly connected to the electric telescopic rod 12, the cylindrical section of the threaded rod 10 passes through the right end of the cavity 9 and is fixedly connected to the motor 5, and the motor 5 is fixedly arranged at the right end of the detection shell 1.

[0024] The beneficial effects of the above technical solution are: When the adjusting mechanism is working, the motor 5 is controlled to work, and the motor 5 drives the threaded rod 10 to rotate, and the threaded rod 10 drives the threaded block 11 and the threaded block 2 17 to slide along the upper end of the cavity 9. After the dust cover 14 moves to the top of the precision mold to be detected, the electric telescopic rod 12 is controlled to extend, and the electric telescopic rod 12 drives the dust cover 14 to move downward until the dust cover 14 moves to the corresponding position of the precision mold to be detected, and the power pump 16 is started to adsorb the impurities in the precision mold to be detected through the dust removal pipe 6 and the dust removal hood 14, and the impurities are sucked into the dust removal box 4. The dust removal pipe 6 is a corrugated pipe, which is convenient for the dust removal pipe 6 to be retracted and extended, ensuring the free movement of the dust collection hood 14. The setting of the guide wheel 13 makes the extension and contraction of the dust removal pipe 6 have a guiding effect. The setting of the placement port facilitates the placement of the precision mold to be detected into the cavity 9. The setting of the opening plate 3 seals the cavity 9 to ensure that the precision mold to be detected is not affected by the outside world during the detection and measurement steps.

[0025] Example 3 On the basis of Example 2, Figure 1-Figure 3As shown, the driving mechanism includes two electric telescopic rods 19, the fixed ends of the two electric telescopic rods 19 are symmetrically arranged on the left and right sides of the upper end of the base 2, and the left and right sides of the base 21 are symmetrically provided with sliding holes 24. The movable end of the electric telescopic rod 19 passes through the sliding hole 24 and is fixedly connected to the tilting block, and the tilting end of the tilting block is slidably connected to the tilting end of the tilting groove 23.

[0026] The beneficial effects of the above technical solution are: When the driving mechanism is working, the electric telescopic rod 19 is controlled to extend. The electric telescopic rod 19 first drives the tilting block to move upward, and the tilting block slides along the tilting groove 23, pushing the connecting block 22 to move in the direction of approaching each other, and the connecting block 22 drives the pushing block 26 to move in the direction of approaching each other. By setting the groove 36 and the spring 25, the pushing block 26 can slide along the groove 36, so that the clamping block 27 has a shock-absorbing effect when clamping the precision mold to be inspected, and the spring 25 has a reset effect to ensure that the clamping block 27 can be reset. After the clamping block 27 and the clamping block 23 clamp the precision mold to be inspected, the electric telescopic rod 19 continues to extend. At this time, the electric telescopic rod 19 drives the base 21 to move upward, and the base 21 drives the sliding block to slide along the sliding groove 18, thereby ensuring the sliding stability of the base 21.

[0027] Example 4 On the basis of Example 1, Figure 1-Figure 4 As shown, the detection mechanism includes a detector 65, which is correspondingly arranged on the upper side of the base 21, and the detector 65 is connected to the second threaded block 17 through a working component, and a spring rod 35 is symmetrically arranged between the fixed shell 68 and the second threaded block 17; The working assembly includes an electric telescopic rod 37, the fixed end of the electric telescopic rod 37 is fixedly connected to the threaded block 2 17, the movable end of the electric telescopic rod 37 is fixedly connected to the working block 38, the working block 38 is connected to the fixed shell 68, the lower end of the fixed shell 68 is provided with a clamping cavity 69, the left and right ends of the clamping cavity 69 are symmetrically provided with operating blocks 53, a spring 51 is fixedly provided between the upper end of the operating block 53 and the clamping cavity 69, a fixed block 2 52 is fixedly provided at the upper end of the operating block 53, the fixed block 2 52 is fixedly connected to the fixed block 3 55, and the fixed block 3 55 is connected to the matching The groove 62 is slidably connected, and a spring two 56 is fixedly provided between the fixed block three 55 and the matching groove 62.

The detector 65 is arranged between the clamping plates 66 on the left and right sides.

[0028] The beneficial effects of the above technical solution are: When the electric telescopic rod 37 is extended and retracted, it can drive the working block 38 to move up and down. When the working block 38 moves up and down, it drives the fixed shell 68 to move up and down. The fixed shell 68 drives the detector 65 to move up and down, which makes it convenient for the detector 65 to detect and measure the precision mold to be detected. When installing the detector 65, pull the operating block 53 downward, the spring 51 is stretched, and the operating block 53 drives the fixed block 3 55 to rotate through the fixed block 2 52. When the fixed block 3 55 rotates, it drives the fixed block 4 70 to rotate. The fixed block 4 70 drives the guide shaft 63 to slide along the rear end of the clamping cavity 69. The guide shaft 63 drives the clamping block three 67 to move in the direction away from each other, and the clamping block three 67 drives the clamping plate 66 to move, and then the precision mold to be inspected is placed between the clamping plates 66 on the left and right sides, and the operating block 53 is released. Under the elastic action of the spring five 51, the operating block 53 returns to its original position, so that the fixed block three 55 and the clamping block three 67 return to their original positions, and the clamping plate 66 returns to its original position, and the clamping height of the detector 65 is adjusted.

[0030] The beneficial effects of the above technical solution are: When the operating block 60 is rotated, the threaded rod 59 is driven to rotate. When the threaded rod 59 rotates, the threaded block 57 moves in a direction away from each other, and the threaded block 57 no longer contacts the lower end of the working block 38. Due to the setting of the spring rod 35, At this time, the electric telescopic rod three 37 extends to drive the working block 38 to move downward. When the working block 38 moves downward, it drives the annular plate 42 to slide along the annular cavity 41. The annular plate 42 drives the elliptical wheel 45 to move downward through the annular sleeve 43. The elliptical wheel 45 slides along the rotating shaft. After the guide hole 39 cooperates with the rotating shaft and the arc groove 40 corresponds to the guide ball 44, the working block 38 can drive the rotating shaft to rotate when it moves downward, and the rotating shaft drives the elliptical wheel 45 to rotate. After the long end of the elliptical wheel 45 is out of contact with the slide plate 46, the connecting plate 48 slides along the through cavity 61 under the elastic action of the spring four 50, and the connecting plate 48 drives the protective sleeve 49 to move in a direction close to each other, so that the protective cavity 58 corresponds to the detector 65. When the detector 65 is not in use, the detector 65 can be protected to prevent the detector 65 from being exposed to the outside for a long time and being easily damaged by the outside world.
