Description

Technical Field

[0001] The present application relates to the technical field of testing tooling, and in particular to a die steel end face detection device. Background Art

[0002] The existing mold steel detection device requires manual clamping and loosening during the detection process, and the existing device can only perform runout detection on a single position of the mold steel end face, resulting in low detection accuracy and low efficiency.

[0003] At present, most detectors use the method of rotating the workpiece, contacting the end face to be measured with a micrometer, and measuring the runout of the end face to be measured by the change in the reading of the micrometer. For example, the technical solutions disclosed in the patents with announcement numbers CN114396844B and CN209763919U. The workpiece to be measured is placed on the testing table and clamped, and then a measuring tool such as a micrometer is contacted with the end face of the workpiece to be measured, and the workpiece to be measured is driven to rotate, and the end face runout of the end face to be measured is measured by the degree of the measuring tool.

[0004] However, in the technical solutions of the above patents, the core devices for detecting end face runout involve multiple mechanical components, such as rotating shafts, floating rings, hinge rods, swing rods, gears, racks, etc. This complex mechanical structure may increase the difficulty of equipment assembly and maintenance, especially in scenarios with high precision requirements, where a slight deviation in any component may affect the overall performance. In particular, the rotatable mounting arm used in the solution of CN114396844B has extremely high requirements for stability, and even slight vibrations will cause fluctuations in the micrometer readings, thereby affecting the detection accuracy. Therefore, this device has many limitations in practical application.

[0005] In addition, the design of the workpiece clamping mechanism in the above scheme is only applicable to mold steel of a specific diameter or shape, such as square, cylindrical and other regular shapes. It has limitations for the detection of non-standard size or special-shaped mold steel and lacks universality. Summary of the invention

[0017] Preferably, the pressing plate is further provided with a transverse abutting end, and the transverse abutting end abuts against a side wall of the workpiece to be measured in a horizontal direction.

[0018] By adopting the above technical solution, the lateral abutment end abuts against the side wall of the workpiece to be measured in the horizontal direction, and the workpiece can be placed at any position on the rotating seat. The lateral abutment end limits the lateral position of the workpiece, thereby avoiding lateral displacement of the workpiece under the action of centrifugal force when the workpiece rotates with the rotating seat, thereby avoiding affecting the measurement accuracy.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-4 The present invention is described in further detail.

[0031] The present application embodiment discloses a die steel end surface detection device. Figure 1The die steel end face detection device is composed of a base 1, a pedestal 2, a rotating seat 3, a clamping mechanism 4, a lifting frame 5, a driving mechanism 6, and a micrometer 7. Specifically, the base 1 serves as the foundation of the entire device and plays a supporting role. A plurality of supporting legs are fixedly arranged at the upper end of the base 1, and the pedestal 2 is arranged above the base 1 and fixedly connected to the supporting legs. The rotating seat 3 is installed at the upper end of the pedestal 2, and the rotating seat 3 is driven to rotate by a motor. The top of the rotating seat 3 is set as a plane, and is a workpiece placement area for placing workpieces of various shapes and sizes to be measured.

[0032] The lifting frame 5 specifically includes a support column 51 and a cantilever 52. The support column 51 is vertically arranged and penetrates the base 2. The support column 51 is vertically slidably connected to the base 2 to facilitate the lifting of the lifting frame 5. The upper end of the support column 51 is located above the rotating seat 3, and the lower end of the support column 51 is located below the base 2. In the embodiment of the present application, the support column 51 can be set as a single one or multiple ones. The cantilever 52 is arranged at the top of the support column 51, and the micrometer 7 is arranged on the cantilever 52.

[0033] The driving mechanism 6 is arranged below the base 2 and connected to the support column 51, so as to drive the lifting frame 5 to move vertically. In the embodiment of the present application, the driving mechanism 6 is preferably an electric push rod with high control accuracy, stability and sensitivity. The electric push rod is fixedly connected to the base 2, and the output end is fixedly connected to the support column 51. Preferably, the driving mechanism 6 can also adopt a cylinder, a hydraulic cylinder, etc., or adopt a motor to drive the support column 51 to rise and fall through a gear rack structure.

[0034] The end of the cantilever 52 has a sliding sleeve 521, which is arranged on the support column 51 and slidably connected to the support column 51 to achieve the up and down movement of the cantilever 52 relative to the support column 51, thereby achieving the height adjustment of the micrometer 7. In addition, the sliding sleeve 521 can be locked in position by a first locking member 522 to ensure sufficient stability. The first locking member 522 can be a fastener such as a bolt or a latch.

[0035] The cantilever 52 is provided with a slide groove 523 along its own length direction, and a fine-tuning sleeve 53 is provided in the slide groove 523. The fine-tuning sleeve 53 can move along the length direction of the slide groove 523 and is locked by a second locking member 524. The second locking member 524 can be a fastener such as a bolt or a latch. A threaded portion is provided on the micrometer 7, and the threaded portion is threadedly connected with the fine-tuning sleeve 53. The head of the micrometer 7 is located above the fine-tuning sleeve 53, and the contact of the micrometer 7 is located below the fine-tuning sleeve 53. The height of the contact of the micrometer 7 can be adjusted by rotating the micrometer 7, thereby achieving fine-tuning. In conjunction with the position adjustment of the cantilever 52, the flexibility of the height adjustment of the micrometer 7 can be improved.

[0036] Furthermore, the clamping mechanism 4 is fixed on the lifting frame 5 and is between the cantilever 52 and the rotating seat 3. The clamping mechanism 4 is driven by the lifting frame 5 to achieve a tight clamping of the workpiece to be measured on the rotating seat 3. Specifically, the clamping mechanism 4 includes an annular seat 41, an annular plate 42 and a pressure plate 43. The annular seat 41 is provided with a sleeve 411, and the sleeve 411 is sleeved on the support column 51, so that the annular seat 41 can move up and down. The clamping mechanism 4 also includes a tensioning spring 44, which is sleeved on the support column 51, and the two ends of the tensioning spring 44 are fixedly connected to the lifting frame 5 and the annular seat 41 respectively. Therefore, the clamping force of the pressure plate 43 on the workpiece to be measured can be flexibly controlled by controlling the deformation of the tensioning spring 44. It meets the clamping requirements of workpieces of different materials, strengths, volumes, and shapes.

[0037] The annular seat 41 and the annular plate 42 are both coaxially arranged with the rotating seat 3, and the annular plate 42 is rotatably connected with the annular seat 41 through a thrust bearing, so that the annular plate 42 can rotate synchronously with the rotating seat 3. The pressing plate 43 is arranged below the annular plate 42 and is used to abut against the top of the workpiece to be measured.

[0038] After the workpiece to be measured is clamped tightly, the rotating seat 3 rotates, driving the workpiece, the pressure plate 43 and the annular plate 42 to rotate synchronously. The contact of the micrometer 7 passes through the inner space of the annular seat 41 and the annular plate 42 and abuts against the end face of the workpiece, so that the end face runout of the workpiece can be measured.

[0039] In order to further adapt to workpieces of different shapes, the position of the pressing plate 43 can be adjusted. Figure 2 The pressing plate 43 is arranged in a long strip shape, and an adjustment groove 431 is provided along the length direction of the pressing plate 43; a connecting shaft 421 is arranged at the bottom of the annular plate 42, and the connecting shaft 421 passes through the adjustment groove 431 and is connected to the pressing plate 43 to realize the rotation and displacement of the pressing plate 43. The middle position of the connecting shaft 421 is set as a groove, so that the connecting shaft 421 is arranged in an I-shaped shape as a whole, and the pressing plate 43 is engaged with the groove, which can realize the rotation and sliding of the pressing plate 43 on the one hand, and can also ensure that the pressing plate 43 has sufficient stability on the other hand. In particular, the pressing plate 43 is made of high-strength metal materials, such as high-carbon steel.

[0040] Furthermore, a plurality of connecting shafts 421 are provided, and the plurality of connecting shafts 421 are evenly arranged around the annular seat 41. One end of the adjusting groove 431 extends to the end of the pressing plate 43 and is open to realize the detachable setting of the pressing plate 43 and the connecting shaft 421, so that the pressing plate 43 can be connected to any connecting shaft 421, effectively improving the flexibility of using the pressing plate 43.

[0041] In addition, the pressing plate 43 can also be connected to any two connecting shafts 421 at the same time, that is, the adjusting slot 431 is clamped to the two connecting shafts 421 at the same time, thereby fixing the pressing plate 43. In this case, the pressing plate 43 can apply a higher clamping force to the workpiece to be measured. And through the cooperation between the pressing plate 43 and the connecting shaft 421 at any position, the flexibility of the pressing plate 43 can be improved, so that any part of the workpiece to be measured can be pressed tightly, thereby achieving effective clamping of the workpiece to be measured.

[0042] Reference Figure 2 and Figure 3 The staff can flexibly select the pressing plates 43 of different lengths according to the distance between the two connecting shafts 421. The number of the pressing plates 43 can be flexibly determined according to the actual clamping requirements.

[0043] Reference Figure 3 As a preferred embodiment of the present application, a bayonet 432 is added to the edge of the pressing plate 43 in the width direction, and the bayonet 432 can be engaged with the connecting shaft 421. The opening of the adjustment slot 431 and the bayonet 432 are respectively located at both ends of the pressing plate 43. When the pressing plate 43 is connected to two connecting shafts 421 at the same time, the adjustment slot 431 cooperates with one of the connecting shafts 421, and the bayonet 432 cooperates with the other connecting shaft 421. The setting of the bayonet 432 can effectively limit the displacement of the pressing plate 43 in the length direction, thereby improving the stability of the pressing plate 43 when clamping.

[0044] Reference Figure 4 In order to further improve the stability of clamping the workpiece to be measured, a transverse abutment end 45 is added to the pressure plate 43. The transverse abutment end 45 includes a connecting buckle 451 and an abutment plate 452. The connecting buckle 451 is engaged with the edge of the pressure plate 43 and can be fixed at any position of the pressure plate 43. The abutment plate 452 is arranged below the pressure plate 43 and connected to the connecting buckle 451. The pressure plate 43 can abut against the top of the workpiece to be measured, and the abutment plate 452 can abut against the side wall of the workpiece to be measured in the horizontal direction. The workpiece can be placed at any position on the rotating seat 3. The transverse abutment end 45 can limit the workpiece laterally to avoid lateral displacement of the workpiece under the action of centrifugal force when the workpiece rotates with the rotating seat 3, thereby avoiding affecting the measurement accuracy.

[0045] Furthermore, a vertical rotating shaft 453 is provided on the connecting buckle 451, and an adjusting screw 454 is passed through the rotating shaft 453. The adjusting screw 454 is horizontally arranged and screwed to the rotating shaft 453, and the abutment plate 452 is fixedly connected to the end of the adjusting screw 454. The direction of the abutment plate 452 can be adjusted by the rotating shaft 453, and the adjusting screw 454 can ensure that the abutment plate 452 is closely fitted to the surface of the workpiece to be measured, thereby providing a stable supporting force.

[0046] The implementation principle of a mold steel end face detection device in the embodiment of the present application is as follows: place the end face to be tested of the workpiece (mold steel) on the rotating seat 3 with the end face to be tested facing upward, and control the lifting frame 5 to move downward by starting the driving mechanism 6, so that the clamping mechanism 4 is close to the upper end face of the workpiece to be tested, and then adjust the position of the pressing plate 43 according to the position and outer shape of the workpiece to be tested. After the adjustment of the pressing plate 43, the lifting frame 5 is controlled to move downward again by the driving mechanism 6, and the pressing plate 43 is tightly abutted against the upper end face of the workpiece to be tested. For workpieces of different materials to be tested, such as plastics, metals, etc., the clamping force can be flexibly adjusted by adjusting the compression amount of the tensioning spring 44 to avoid damage to the material caused by excessive clamping force or loosening of the workpiece caused by insufficient clamping force.

[0047] Finally, the adjusting screw 454 is operated to make the abutting plate 452 abut against the side wall of the workpiece to be measured, thereby ensuring the lateral stability of the workpiece to be measured and preventing the workpiece from being laterally offset under the action of centrifugal force when rotating with the rotating seat 3 .

[0048] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, all equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
