Abstract
Description
Technical Field
[0001] This utility model relates to the field of product inspection tooling technology, and more specifically, to a workpiece inspection device. Background Technology
[0002] After the casting is completed and the casting is machined, it is necessary to inspect the key dimensional parameters of the workpiece. For example, a ring-shaped workpiece has appeared on the market. The outer wall of the lower end of the workpiece is provided with an annular protrusion. The upper end surface of the annular protrusion forms an annular conical surface that gradually slopes downward from the inside to the outside along the radial direction of the workpiece. The flatness of the annular conical surface in the circumferential direction is an important dimensional parameter of the workpiece. However, there is currently no device on the market to inspect the flatness of the annular conical surface on the workpiece, which means that there is a defect that the annular conical surface on the workpiece cannot be inspected. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a workpiece inspection device that can inspect the flatness of the annular conical surface on an annular workpiece to meet the inspection requirements of the workpiece.
[0004] This utility model provides a workpiece inspection device, including a support plate, a support block, and a dial indicator. The support plate is used to support a ring-shaped workpiece. The upper end of the support plate is provided with a groove, and the lower end of the workpiece is inserted into the groove and rotates with the groove. The shape of the outer edge of the groove is adapted to the shape of the outer edge of the workpiece. The support block is fixed on the upper end of the support plate and located on one side of the groove. The dial indicator is fixed on the support block. The upper end surface of the outer edge of the workpiece forms an annular conical surface. The annular conical surface gradually slopes downward from the inside to the outside along the radial direction of the workpiece. The probe of the dial indicator abuts against the annular conical surface.
[0005] By adopting the above-described structure, this utility model allows for the following operation: the workpiece is placed on the support plate with its lower end inserted into the recess. The dial indicator probe then abuts against the annular conical surface on the outer edge of the workpiece. The workpiece is then manually rotated, allowing the dial indicator probe to move circumferentially along the annular conical surface. Simultaneously, the operator observes the dial indicator reading. After the workpiece rotates one full circle relative to the support plate (i.e., the dial indicator probe moves one full circle along the annular conical surface), if the dial indicator reading is within the normal range, the flatness of the annular conical surface meets the dimensional requirements. Conversely, if the reading is outside the normal range, the flatness of the annular conical surface does not meet the dimensional requirements, and the workpiece is considered defective. This utility model enables the inspection of the flatness of the annular conical surface on an annular workpiece, thus meeting the workpiece inspection requirements.
[0006] In one possible implementation, the outer edge of the settling tank forms an annular chamfered surface, which gradually slopes downward from the outside to the inside along the radial direction of the settling tank. By setting an annular chamfered surface at the outer edge of the settling tank, when the workpiece is placed on the support plate, the lower end of the workpiece can more easily enter the settling tank and rotate with the settling tank under the guidance of the annular chamfered surface. Furthermore, under the action of the annular guide surface, when the workpiece rotates relative to the support plate, the workpiece can be more reliably confined in the settling tank, thereby improving the reliability of the rotational engagement between the workpiece and the support plate, and effectively preventing radial displacement of the workpiece.
[0007] In one possible implementation, the support block is L-shaped; the inner walls of the two right-angled sides of the support block abut against the sidewall of the outer edge of the workpiece; by adopting this structure, when the workpiece is pushed by a finger to rotate relative to the support plate, under the action of the two right-angled sides of the support block, since the inner walls of the two right-angled sides of the support block abut against the sidewall of the outer edge of the workpiece, the radial limit of the workpiece can be further achieved to avoid radial displacement of the workpiece.
[0008] In one possible implementation, the support block is provided with a socket, into which the probe sleeve of the dial indicator is inserted and tightly fitted; with this structure, the dial indicator can be reliably and conveniently assembled onto the support block.

Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.
[0014] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.
[0015] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0016] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0017] See Figure 1-4 As shown in the embodiment of this application, a workpiece inspection device is disclosed, including a support plate 1, a support block 2, and a dial indicator 3. The support plate 1 is used to support a ring-shaped workpiece 4. A groove 11 is provided at the upper end of the support plate 1. The lower end of the workpiece 4 is inserted into the groove 11 and rotates with the groove 11. The shape of the outer edge of the groove 11 is adapted to the shape of the outer edge of the workpiece 4. The support block 2 is fixed at the upper end of the support plate 1 and located on one side of the groove 11. The dial indicator 3 is fixed on the support block 2. The upper end surface of the outer edge of the workpiece 4 forms an annular conical surface 41. The annular conical surface 41 gradually slopes downward from the inside to the outside along the radial direction of the workpiece 4. The probe 31 of the dial indicator 3 abuts against the annular conical surface 41. When using this invention, the workpiece is placed on the support plate, with its lower end inserted into the groove. At this time, the dial indicator probe can abut against the annular conical surface on the outer edge of the workpiece. Then, the workpiece is rotated manually. The dial indicator probe can move along the circumferential direction of the annular conical surface. At the same time, the operator observes the dial indicator reading. After the workpiece rotates one full circle relative to the support plate, that is, after the dial indicator probe moves one full circle along the annular conical surface, if the dial indicator reading is within the normal range, it indicates that the flatness of the annular conical surface meets the dimensional requirements. Otherwise, it indicates that the flatness of the annular conical surface does not meet the dimensional requirements, and the workpiece is a defective product.
[0018] The outer edge of the settling tank 11 forms an annular chamfered surface 12, which gradually slopes downward from the outside to the inside along the radial direction of the settling tank 11. By setting an annular chamfered surface at the outer edge of the settling tank, when the workpiece is placed on the support plate, the lower end of the workpiece can more easily enter the settling tank and rotate with the settling tank under the guidance of the annular chamfered surface. Under the action of the annular guide surface, when the workpiece rotates relative to the support plate, the workpiece can be more reliably confined in the settling tank, thereby improving the reliability of the rotational engagement between the workpiece and the support plate, and effectively avoiding radial displacement of the workpiece.
[0019] The support block 2 is L-shaped; the inner walls of the two right-angled sides of the support block 2 abut against the side wall of the outer edge of the workpiece 4. With this structure, when the workpiece is pushed by the finger to rotate relative to the support plate, the inner walls of the two right-angled sides of the support block abut against the side wall of the outer edge of the workpiece, thereby further limiting the radial movement of the workpiece to avoid radial displacement of the workpiece.
[0020] The support block 2 is provided with a socket 21, and the measuring rod sleeve 32 of the dial indicator 3 is inserted into the socket 21 and tightly fitted with the socket 21; by adopting this structure, the dial indicator can be reliably and conveniently assembled on the support block.
[0021] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
