Description

Technical Field

[0001] This utility model belongs to the field of profilometer technology, specifically a profilometer for testing powder metallurgy molds. Background Technology

[0002] A profilometer is a precision instrument used to accurately measure the surface morphology, geometric features, and microstructure of an object. It is widely used in industrial manufacturing, scientific research experiments, and quality inspection. It captures three-dimensional or two-dimensional data of the object's surface through high-precision sensors, and then analyzes and processes the data through computer software to achieve accurate measurement of the profile.

[0003] When using a profilometer to inspect powder metallurgy molds, the equipment must first be calibrated in a stable environment and the mold surface cleaned. Then, a suitable clamping method is selected according to the mold shape and the measurement parameters are set. During the measurement process, three-dimensional profile data is acquired through contact or non-contact scanning, and a point cloud model is automatically generated. Finally, specialized software is used to analyze geometric dimensions, form and position tolerances, and surface defects to achieve a high-precision and high-efficiency comprehensive quality assessment.

[0004] In the existing technology, the profilometer consists of a worktable, a profilometer detection body, a drive control system, and auxiliary fixing components. When the mold is clamped and fixed by the fixing components, the mold needs to be fixed at a certain vertical tilt angle. Due to the diverse shapes and irregular structures of the molds, the contact areas between the two clamps and the outer side of the mold are different when clamping and fixing the mold, which will cause the mold to be horizontally offset in different directions when fixed. This makes the alignment between the detection centerline position and the stylus of the existing molds of different specifications cumbersome. In view of this, a profilometer for powder metallurgy mold detection is proposed to solve the above problems. Summary of the Invention

[0005] To address the problems mentioned in the background section, this utility model provides a profilometer for testing powder metallurgy molds.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a profilometer for testing powder metallurgy molds, comprising a worktable, a lifting mechanism fixedly mounted on the top of the worktable, a profilometer testing body mounted at the bottom of the lifting mechanism, a positioning plate mounted on the top of the worktable, a stop block detachably mounted on the top of the positioning plate, a fixed plate slidably mounted on the top of the positioning plate, a clamping block mounted on the fixed plate, a threaded rod rotatably mounted on the inner side of the clamping block, the threaded rod being threaded to the other side of the fixed plate, for driving the clamping block to clamp the mold with a protrusion near the fixed plate, an L-shaped plate A or an L-shaped plate B fixedly mounted on the outer sides of the protrusion and the clamping block respectively, inner sliding strips mounted on the outer sides of both L-shaped plates A and B, and a binding strap between the inner sliding strips on both sides for supporting the bottom of the inclined mold.

[0007] Preferably, the inner sliding strips on both sides are symmetrically arranged between L-shaped plate A and L-shaped plate B.

[0008] Preferably, the outer side of the L-shaped plate A is provided with a sleeve strip, the outer side of the L-shaped plate B is provided with an outer sleeve strip, the inner side of the sleeve strip is provided with an outer sleeve strip, and the sleeve strip and the outer sleeve strip are located between the L-shaped plate A and the L-shaped plate B.

[0009] Preferably, the outer sides of the L-shaped plate A and L-shaped plate B are provided with through holes, and a top rod is slidably provided inside the through holes. The top rod is fixedly provided outside the inner slide bar, located between the L-shaped plate A and the corresponding inner slide bar and between the L-shaped plate B and the corresponding inner slide bar, and respectively passes through the L-shaped plate A or the top rod on the corresponding side.

[0010] Preferably, the inner slide bar is arc-shaped and is made of a thin metal sheet.

[0011] Preferably, a rubber block is connected between the sleeve strip and the restraint strap to support the middle of the restraint strap when it is stretched.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, through the cooperation of a positioning plate, a fixing plate, a clamping block, and a threaded rod, can firmly clamp molds of different sizes, preventing displacement of the molds during the inspection process and ensuring the accuracy of the inspection data.

[0015] 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.

[0016] like Figures 1 to 3 As shown, this utility model provides a profilometer for testing powder metallurgy molds, including a worktable 1, a lifting mechanism 2 fixedly mounted on the top of the worktable 1, a profilometer testing body 3 mounted at the bottom of the lifting mechanism 2, a positioning plate 4 mounted on the top of the worktable 1, a stop block 5 detachably mounted on the top of the positioning plate 4, a fixed plate 7 slidably mounted on the top of the positioning plate 4, a clamping block 8 mounted on the fixed plate 7, a threaded rod 9 rotatably mounted on the inner side of the clamping block 8, the threaded rod 9 being threaded to the other side of the fixed plate 7, used to drive the clamping block 8 to clamp the mold with a protrusion near the fixed plate 7, an L-shaped plate A10 or an L-shaped plate B11 fixedly mounted on the outer side of the protrusion and the clamping block 8 respectively, an inner slide bar 14 mounted on the outer side of both the L-shaped plate A10 and the L-shaped plate B11, a binding strap 15 mounted between the two inner slide bars 14 for supporting the bottom of the inclined mold, the two inner slide bars 14 being symmetrically arranged between the L-shaped plate A10 and the L-shaped plate B11.

[0017] When performing contour inspection on a powder metallurgy mold, the mold to be inspected is first placed on the fixed plate 7, between the fixed plate 7 and the clamping block 8. Then, the clamping block 8 is rotated and moved towards the protrusion on the side closer to the fixed plate 7, thereby achieving clamping and fixing of the mold by the clamping block 8 and the protrusion. When the mold is vertically tilted, the bottom of the tilted mold can be supported by the binding strap 15 between the inner slide strips 14 on both sides between the L-shaped plate A10 and the L-shaped plate B11. Together with the clamping block 8 and the protrusion fixing the mold, a binding effect is formed between the two tilted points, ensuring the stability of the mold during the inspection process. Finally, the lifting mechanism 2 is started, which drives the contour measuring instrument test body 3 at the bottom to move up and down, adjusting the distance between the contour measuring instrument test body 3 and the mold, so that the contour measuring instrument test body 3 can accurately inspect the mold contour (the lifting mechanism 2 and the contour measuring instrument test body 3 are existing technologies and will not be described in detail here).

[0018] like Figure 3 As shown, the outer side of the L-shaped plate A10 is provided with a sleeve strip 12, the outer side of the L-shaped plate B11 is provided with an outer sleeve strip 13, and the inner side of the sleeve strip 12 is provided with an outer sleeve strip 13. The sleeve strip 12 and the outer sleeve strip 13 are located between the L-shaped plate A10 and the L-shaped plate B11. A rubber block is connected between the sleeve strip 12 and the restraint strap 15, which is used to support the middle part of the restraint strap 15 when the restraint strap 15 is stretched.

[0019] For molds of different widths, the distance between the clamping block 8 and the protrusion on one side of the fixing plate 7 changes accordingly. At the same time, the sleeve strip 12 slides between the outer sleeve strip 13 to adapt to the distance change. During this process, the binding strap 15 is stretched, and the rubber block supports the middle of the stretched binding strap 15, thereby adapting to molds of different widths.

[0020] like Figure 3 As shown, through holes are provided on the outer sides of L-shaped plates A10 and B11, and top rods 16 are slidably provided on the inner side of the through holes. The top rods 16 are fixed on the outer side of the inner slide strips 14, located between L-shaped plates A10 and the corresponding inner slide strips 14 and L-shaped plates B11 and the corresponding inner slide strips 14, and respectively pass through the L-shaped plates A10 or the top rods 16 on the corresponding side. The inner slide strips 14 are arc-shaped and are made of thin metal sheets.

[0021] When the mold is fixed, if the mold tilts horizontally, the mold centerline will be displaced. At the same time, the inner slide bar 14 and the binding band 15 will be affected by the mold tilt and shift to the same side of the tilt. Since the inner slide bar 14 is arc-shaped and made of thin metal sheet, it can adapt to the offset movement. At this time, the inner slide bar 14 on the tilted side will drive the ejector rod 16 to move to one side through the through hole. At this time, the inspector can observe the offset distance and adjust the position accordingly to ensure that the mold centerline is restored.

[0022] Working principle and usage process of this utility model: When performing contour inspection on a powder metallurgy mold, the mold to be inspected is first placed on the fixed plate 7, between the fixed plate 7 and the clamping block 8. Then, the clamping block 8 is rotated and moved towards the protrusion on the side closer to the fixed plate 7, thereby achieving clamping and fixing of the mold by the clamping block 8 and the protrusion. When the mold is vertically tilted, the bottom of the tilted mold can be supported by the binding strap 15 between the inner slide bars 14 on both sides between the L-shaped plate A10 and the L-shaped plate B11. Together with the clamping block 8 and the protrusion fixing the mold, a binding effect is formed between the two tilted points, ensuring the stability of the mold during the inspection process. At the same time, when the mold tilts horizontally, the mold centerline position is disengaged. Simultaneously, the inner slide bars 14 and the binding strap 15 are affected by the tilt of the mold and shift to the same tilted side. Since the inner slide bars 14 are arc-shaped and made of thin metal sheets, they can adapt to the offset action. Finally, the lifting mechanism 2 is activated, which drives the contour measuring instrument test body 3 at the bottom to move up and down, adjusting the distance between the contour measuring instrument test body 3 and the mold, so that the contour measuring instrument test body 3 can accurately inspect the mold contour.
