Description
Technical Field
[0001] This application relates to the field of measurement technology, and more specifically to a measuring device. Background Technology
[0002] When manufacturing workpieces using molds, to facilitate the smooth removal of the formed workpiece from the mold, an angle is usually set between the tangential direction of the side where the workpiece intersects the mold parting surface and the normal direction of the mold parting surface; this angle is called the draft angle. The draft angle of a workpiece is typically measured by measuring the step difference between two points on the same vertical plane of the workpiece surface. Currently, gauges are commonly used for this measurement.
[0003] However, because it is necessary to measure the step difference at multiple locations on the workpiece surface, there are many measurement points. Using only a measuring instrument makes the operation complex and inefficient. In addition, moving the workpiece or the measuring instrument can easily cause the zero point position to change, resulting in inaccurate measurements. Utility Model Content
[0004] In view of the above, it is necessary to propose a measuring device that can fix the workpiece and slide the gauge along a preset direction, thereby simplifying the measurement operation, improving the measurement efficiency, and increasing the detection accuracy.
[0005] This application provides a measuring device, including: a base; a measuring mechanism including a sliding component, a fixed head, and a measuring gauge, wherein the sliding component is slidably connected to the base along a first direction, the fixed head is fixedly connected to the sliding component and disposed along a second direction perpendicular to the first direction, the measuring gauge is connected to the sliding component and disposed along the second direction, and the measuring gauge has a measuring head disposed above the fixed head along a third direction perpendicular to the first and second directions; and a positioning mechanism connected to the base and spaced apart from the sliding component along the second direction, the positioning mechanism being used to position a workpiece and orient the workpiece's test surface toward the measuring gauge; wherein the fixed head and the measuring head of the measuring gauge are configured to abut against the test surface of the workpiece, the measuring gauge is used to detect the step difference between the abutment position of the fixed head and the abutment position of the measuring head of the measuring gauge on the test surface of the workpiece, and the sliding component is used to move the fixed head and the measuring gauge along the first direction to detect the step differences at multiple positions of the workpiece.
[0006] In the aforementioned measuring device, the sliding component of the measuring mechanism is slidably connected to the base, and both the fixed meter head and the measuring gauge are connected to the sliding component. The sliding component allows the fixed meter head and the measuring gauge to slide along the base. The positioning mechanism positions the workpiece, and the fixed meter head abuts against the surface to be measured on the workpiece. The measuring head of the measuring gauge is positioned above the fixed meter head. When the fixed meter head abuts against the workpiece, the measuring head of the measuring gauge also abuts against the workpiece, thus enabling the detection of surface differences on the workpiece. During the measurement process, the fixed meter head serves as a reference point, eliminating the need for calibration and zeroing, resulting in simple operation and high measurement accuracy. When other points on the workpiece surface need to be measured, simply moving the sliding component moves the fixed meter head and the measuring gauge, allowing measurement of other points. This simplifies the measurement operation and effectively improves detection efficiency.

The sliding protrusion is slidably disposed in the sliding groove so that the sliding portion and the connecting portion are slidably connected. The width of the sliding groove along the first direction is smaller than the width of the stop portion along the first direction so that the stop portion can abut against the connecting portion, thereby stopping the movement of the measuring seat.
[0009] In some embodiments, the sliding assembly further includes a push handle connected to the connecting portion and abutting against the stop portion. The push handle is used to push the stop portion away from the positioning mechanism, thereby driving the fixed meter head and the measuring meter head away from the positioning mechanism.

[0011] In some embodiments, the base has a sliding hole that passes through the base along the third direction and is disposed along the first direction; the sliding assembly further includes a sliding connector that passes through the sliding hole from the side of the base away from the sliding seat and is connected to the sliding seat, and the width of the end of the sliding connector away from the sliding seat along the second direction is greater than the width of the sliding hole along the second direction.
[0012] In some embodiments, the base has a limiting groove extending in the first direction on the side facing the sliding seat, and the sliding seat has a limiting protrusion adapted to the limiting groove on the side facing the base. The limiting protrusion is slidably disposed in the limiting groove to limit the sliding seat in the second direction.
[0013] In some embodiments, the positioning mechanism includes a material carrier, a pushing component, and a stop. The material carrier is connected to the base and spaced apart from the sliding component along the second direction. The material carrier is used to support the workpiece. The pushing component is connected to the side of the material carrier away from the sliding component. The stop is connected to the side of the material carrier close to the sliding component. The pushing component is used to push the workpiece against the stop to position the workpiece.
[0014] In some embodiments, the pushing assembly includes a fixing member, a pushing member, a push rod, a second elastic member, and a positioning handle. The fixing member is fixedly connected to the material carrier, and the pushing member is slidably connected to the fixing member along the second direction. One end of the pushing member is disposed towards the stop member. The material carrier has a second receiving groove corresponding to the pushing member. The push rod is connected to the pushing member and extends into the second receiving groove along the third direction. The second elastic member is disposed in the second receiving groove, and both ends of the second elastic member abut against the push rod and the side wall of the second receiving groove away from the stop member, respectively.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0023] The embodiments of this application will be further described below with reference to the accompanying drawings. To facilitate understanding and explanation of the embodiments of this application, a three-dimensional coordinate system is established in some of the drawings, with the Y-axis direction as the first direction, the X-axis direction as the second direction, and the Z-axis direction as the third direction. The X-axis direction, Y-axis direction, and Z-axis direction are perpendicular to each other.
[0024] Please see Figure 1 , Figure 2 and Figure 3 This application provides a measuring device 100 for detecting the dimensions of a measurement point on a workpiece 200, wherein the dimensions of the measurement point may be, but are not limited to, depth, height, and step difference. The measuring device 100 includes a base 10, a measuring mechanism 20, and a positioning mechanism 30.
[0025] Specifically, the base 10 is roughly plate-shaped. To improve the stability of the base 10 during use and to facilitate operation by workers, multiple support legs can be provided on the lower side of the base 10.
[0026] The measuring mechanism 20 includes a sliding component 21, a fixed head 22, and a measuring gauge 23. The sliding component 21 is slidably connected to the base 10 along a first direction. The fixed head 22 is fixedly connected to the sliding component 21 and is arranged along a second direction perpendicular to the first direction. The measuring gauge 23 is connected to the sliding component 21 and is arranged along the second direction. The measuring gauge 23 has a measuring head 233, which is arranged above the fixed head 22 along a third direction perpendicular to the first and second directions. The fixed head 22 can be a conical structure, and the end of the fixed head 22 that abuts against the workpiece 200 is a pointed structure, which can improve the accuracy of the abutment position of the fixed head 22. The measuring gauge 23 includes a body 231, a rod 232 fixedly connected to the body 231, and a measuring head 233 slidably connected to the rod 232. During measurement, the measuring head 233 abuts against the point to be measured, and the body 231 displays the measurement result.
[0027] The positioning mechanism 30 is connected to the base 10 and is spaced apart from the sliding component 21 along the second direction. The positioning mechanism 30 is used to position the workpiece 200 and make the test surface of the workpiece 200 face the vector table 23.
[0028] The measuring head 233 of the fixed head 22 and the measuring head 23 of the measuring head 23 are configured to abut against the surface to be measured of the workpiece 200. The measuring head 23 is used to detect the step difference between the abutting position of the fixed head 22 and the abutting position of the measuring head 233 of the measuring head 23 on the surface to be measured of the workpiece 200. The sliding component 21 is used to move the fixed head 22 and the measuring head 23 along the first direction to detect the step difference at multiple positions of the workpiece 200.
[0029] It is understood that a standard block (not shown in the figure) can also be configured in this application. The standard block can be fixed by the positioning mechanism 30. Before measurement, the measuring head 233 of the fixed meter head 22 and the measuring head 233 of the measuring meter 23 can be simultaneously abutted against the standard block to zero the measuring meter 23. During measurement, the standard block is removed, and the workpiece 200 is installed on the positioning mechanism 30 to perform the measurement. There is no need to zero it again during the measurement process.
[0030] In the measuring device 100 provided in this embodiment, the sliding component 21 of the measuring mechanism 20 is slidably connected to the base 10. The fixed meter head 22 and the measuring gauge 23 are both connected to the sliding component 21, allowing the fixed meter head 22 and the measuring gauge 23 to slide along the base 10 via the sliding component 21. The positioning mechanism 30 can position the workpiece 200. The fixed meter head 22 can abut against the surface to be measured on the workpiece 200. The measuring head 233 of the measuring gauge 23 is positioned above the fixed meter head 22. When the fixed meter head 22 abuts against the workpiece 200, the measuring head 233 of the measuring gauge 23 also abuts against the workpiece 200, thereby enabling the detection of the step difference on the surface of the workpiece 200. During the measurement process, the fixed meter head 22 serves as a reference point, eliminating the need for calibration and zeroing, resulting in simple operation and high measurement accuracy. When it is necessary to measure other points on the surface of the workpiece 200, simply moving the sliding component 21 will drive the fixed meter head 22 and the gauge 23 to move, thereby enabling the measurement of other points. This simplifies the measurement operation and effectively improves the detection efficiency.
[0031] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The sliding assembly 21 includes a sliding seat 211, a measuring seat 212, a baffle 213, and a first elastic member 214. The sliding seat 211 is slidably connected to the base 10 along a first direction, and the measuring seat 212 is slidably connected to the sliding seat 211 along a second direction. The fixed meter head 22 and the meter 23 are both connected to the measuring seat 212. The measuring seat 212 has a first receiving groove 2121 on the side facing the sliding seat 211. The baffle 213 is connected to the sliding seat 211 and extends into the first receiving groove 2121 along a third direction. The first elastic member 214 is disposed in the first receiving groove 2121, and the two ends of the first elastic member 214 abut against the baffle 213 and the side wall of the first receiving groove 2121 near the positioning mechanism 30, respectively. The first elastic member 214 is used to push the measuring seat 212 to move toward the positioning mechanism 30.
[0032] The measuring seat 212 is slidably connected to the sliding seat 211 along the second direction, allowing the fixed meter head 22 and the gauge 23 to be finely adjusted in the second direction, ensuring close contact with the surface of the workpiece 200 and improving measurement stability. A baffle 213 is connected to the sliding seat 211 and extends into the first receiving groove 2121 of the measuring seat 212. A first elastic element 214 is disposed within the first receiving groove 2121, continuously pushing the measuring seat 212 toward the positioning mechanism 30. This ensures that the measuring meter head 233 of the fixed meter head 22 and the gauge 23 is always in close contact with the surface of the workpiece 200, avoiding measurement errors caused by looseness or gaps. The baffle 213 can be a sheet structure, and the first elastic element 214 can be a spring, etc. The first elastic element 214 can automatically adjust the position of the measuring seat 212 according to minute changes in the surface of the workpiece 200, ensuring that the measuring meter head 233 of the fixed meter head 22 and the gauge 23 always maintains optimal contact with the surface of the workpiece 200. This automatic adjustment function significantly improves measurement accuracy.
[0033] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The measuring seat 212 includes a sliding portion 2122 and a stop portion 2123 connected together. The sliding portion 2122 is provided with a sliding protrusion 2122a, and the stop portion 2123 is provided on the side of the sliding portion 2122 away from the positioning mechanism 30. The sliding seat 211 is provided with a connecting portion 2111, and the connecting portion 2111 has a sliding groove 2112 adapted to the sliding protrusion 2122a. The sliding protrusion 2122a is slidably disposed in the sliding groove 2112, so that the sliding portion 2122 and the connecting portion 2111 are slidably connected. The width of the sliding groove 2112 in the first direction is smaller than the width of the stop portion 2123 in the first direction, so that the stop portion 2123 can abut against the connecting portion 2111, thereby stopping the movement of the measuring seat 212.
[0034] The sliding part 2122 is provided with a sliding protrusion 2122a, and the sliding seat 211 is provided with a sliding groove 2112 that matches the sliding protrusion 2122a. The sliding protrusion 2122a slides within the sliding groove 2112, ensuring the movement accuracy of the measuring seat 212 in the second direction, reducing the shaking of the measuring seat 212 during sliding, and improving the stability of the measurement. The tight fit between the sliding protrusion 2122a and the sliding groove 2112 ensures a stable connection between the measuring seat 212 and the sliding seat 211, reducing possible loosening or displacement during the measurement process and enhancing the stability of the structure. The sliding of the sliding protrusion 2122a within the sliding groove 2112 also provides clear guidance for the movement of the measuring seat 212. The stop portion 2123 is disposed on the side of the sliding portion 2122 away from the positioning mechanism 30. The width of the sliding groove 2112 along the first direction is smaller than the width of the stop portion 2123 along the first direction, so that the stop portion 2123 can abut against the connecting portion 2111 of the sliding seat 211, limiting the sliding range of the measuring seat 212, preventing the measuring seat 212 from moving excessively, and further improving the motion accuracy.
[0035] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The sliding component 21 also includes a push handle 215, which is connected to the connecting part 2111 and abuts against the stop part 2123. The push handle 215 is used to push the stop part 2123 away from the positioning mechanism 30, thereby driving the fixed meter head 22 and the measuring meter head 233 away from the positioning mechanism 30.
[0036] In this embodiment, the push handle 215 is a rod-shaped structure with an eccentric structure. The connecting part 2111 of the push handle 215 is rotatably connected around a third direction, and the eccentric structure of the push handle 215 abuts against the stop part 2123. When installing or removing the workpiece 200 from the positioning mechanism 30, rotating the push handle 215 can push the stop part 2123 to move away from the positioning mechanism 30 in the second direction. In turn, the stop part 2123 drives the sliding part 2122, as well as the fixed meter head 22 and the measuring meter 23, to move away from the positioning mechanism 30 in the second direction, so as to avoid the positioning mechanism 30 and prevent the measuring meter head 233 of the fixed meter head 22 and the measuring meter 23 from affecting the installation or removal of the workpiece 200. After the workpiece 200 is installed, rotate the push handle 215 so that the eccentric structure of the push handle 215 rotates away from the stop part 2123. The first elastic element 214 pushes the sliding part 2122 to move towards the positioning mechanism 30 in the second direction, thereby driving the fixed meter head 22 and the measuring meter head 233 to abut against the workpiece 200, so that measurement can be performed.
[0037] In some embodiments, see Figure 1 , Figure 2 and Figure 3The sliding part 2122 has a receiving hole 2122b extending in the second direction, and the stop part 2123 has a connecting hole 2123a coaxially arranged with the receiving hole 2122b. The gauge 23 is inserted into the connecting hole 2123a, and the measuring head 233 of the gauge 23 is movably disposed in the receiving hole 2122b and extends out of the receiving hole 2122b near the end of the positioning mechanism 30. The sliding assembly 21 also includes a locking sleeve 216, which is disposed in the connecting hole 2123a and sleeved on the gauge 23.
[0038] It is understood that the gauge rod 232 of the gauge 23 is inserted into the connecting hole 2123a, and the locking sleeve 216 is disposed in the connecting hole 2123a and sleeved on the gauge rod 232 of the gauge 23. The locking sleeve 216 can be made of plastic steel, which can improve the connection stability between the gauge 23 and the stop part 2123, thereby improving the stability of the gauge 23 during the measurement process. The connection between the gauge 23 and the stop part 2123 can be achieved by installing a countersunk bolt on the stop part 2123. The countersunk bolt passes through the stop part 2123 and abuts against the locking sleeve 216, thereby locking the gauge 23 with the locking sleeve 216. Of course, this is not intended to limit the embodiments of this application. The measuring head 233 of the gauge 23 is movably disposed in the receiving hole 2122b, so that the measuring head 233 of the gauge 23 can be protected by the sliding part 2122.
[0039] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The base 10 has a sliding hole 11 that passes through the base 10 in a third direction and is arranged in a first direction. The sliding assembly 21 also includes a sliding connector 217, which passes through the sliding hole 11 from the side of the base 10 away from the sliding seat 211 and is connected to the sliding seat 211. The width of the end of the sliding connector 217 away from the sliding seat 211 in the second direction is greater than the width of the sliding hole 11 in the second direction.
[0040] The sliding connector 217 passes through the sliding hole 11 of the base 10 and connects to the sliding seat 211. The width of its end furthest from the sliding seat 211 along the second direction is greater than the width of the sliding hole 11, forming an effective limiting structure. This prevents the sliding seat 211 from shifting or wobbling during sliding, ensuring smooth movement of the sliding assembly 21 along the first direction and improving measurement stability. The design of the sliding connector 217 significantly enhances the stability, motion accuracy, and durability of the sliding assembly 21. The limiting function of the sliding connector 217 reduces offset and vibration during sliding, improving measurement accuracy and efficiency. Simultaneously, the sliding connector 217 has a simple structure, is easy to install and maintain, and reduces the manufacturing and maintenance costs of the device.
[0041] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The base 10 has a limiting groove 12 extending in a first direction on the side facing the sliding seat 211. The sliding seat 211 has a limiting protrusion 2113 adapted to the limiting groove 12 on the side facing the base 10. The limiting protrusion 2113 is slidably disposed in the limiting groove 12 to limit the sliding seat 211 in a second direction. The limiting protrusion 2113, slidably disposed within the limiting groove 12, provides clear guidance for the movement of the sliding assembly 21 in the first direction, ensuring that the sliding assembly 21 will not deviate or wobble during movement, significantly improving the stability of the movement. The limiting groove 12 provides precise guidance for the limiting protrusion 2113, ensuring more accurate movement of the sliding assembly 21 in the first direction and avoiding measurement errors caused by sliding deviations.
[0042] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The positioning mechanism 30 includes a material carrier 31, a pushing component 32, and a stop 33. The material carrier 31 is connected to the base 10 and is spaced apart from the sliding component 21 along the second direction. The material carrier 31 is used to support the workpiece 200. The pushing component 32 is connected to the side of the material carrier 31 away from the sliding component 21. The stop 33 is connected to the side of the material carrier 31 close to the sliding component 21. The pushing component 32 is used to push the workpiece 200 against the stop 33 to position the workpiece 200.
[0043] The material carrier 31 is generally plate-shaped to provide stable support for the workpiece 200. Two pushing components 32 can be provided, spaced apart along the first direction, to push against the workpiece 200 from both ends, providing stability when positioning the workpiece 200. Two stop components 33 can be provided, respectively positioned opposite to both ends of the workpiece 200 along the first direction. This not only works with the pushing components 32 to improve the stability of positioning the workpiece 200, but also avoids obstruction at the test points of the workpiece 200.
[0044] In some embodiments, see Figure 1 , Figure 2 and Figure 3The pushing assembly 32 includes a fixing member 321, a pushing member 322, a push rod 323, a second elastic member 324, and a positioning handle 325. The fixing member 321 is fixedly connected to the material carrier 31, and the pushing member 322 is slidably connected to the fixing member 321 along a second direction. One end of the pushing member 322 is positioned towards the stop member 33. The material carrier 31 has a second receiving groove 311 corresponding to the pushing member 322. The push rod 323 is connected to the pushing member 322 and extends into the second receiving groove 311 along a third direction. The second elastic member 324 is positioned on the first... Two receiving grooves 311 are provided, and the two ends of the second elastic member 324 abut against the push rod 323 and the side wall of the second receiving groove 311 away from the stop member 33, respectively. The second elastic member 324 is used to push the push rod 323, thereby driving the push member 322 to move towards the stop member 33 in the second direction, so that the push member 322 pushes the workpiece 200 to the stop member 33. The positioning handle 325 is connected to the end of the push member 322 away from the stop member 33 and abuts against the material carrier 31. The positioning handle 325 is used to pull the push member 322 away from the stop member 33.
[0045] The fixing member 321 is generally a block structure, the pushing member 322 is generally a rod structure, the push rod 323 is generally a column structure, the second elastic member 324 can be a spring, the positioning handle 325 is a rod structure and has an eccentric structure, the positioning handle 325 is rotatably connected to the pushing member 322 around the first direction, and the eccentric structure of the positioning handle 325 abuts against the material carrier 31.
[0046] Before installing workpiece 200, the positioning handle 325 is rotated about a first direction. The eccentric structure of the positioning handle 325 pushes against the material carrier 31, thereby causing the positioning handle 325 to pull the pushing member 322 away from the stop member 33 along a second direction. The pushing member 322 drives the push rod 323 to compress the second elastic member 324. Then, the workpiece 200 is placed on the material carrier 31 and aligned with the stop member 33. When positioning the workpiece 200, the positioning handle 325 is rotated in the opposite direction about the first direction. The eccentric structure of the positioning handle 325 rotates away from the material carrier 31. The second elastic member 324 pushes against the push rod 323, and the push rod 323 moves towards the workpiece 200 along the second direction, thereby pushing the workpiece 200 to the stop member 33, thus completing the positioning of the workpiece 200.
[0047] When the workpiece 200 has an irregular shape, such as different widths in the second direction, the length of the pushing member 322 at different positions of the corresponding workpiece 200 is adapted to the workpiece 200.
[0048] In some embodiments, see Figure 1 , Figure 2 and Figure 3The positioning mechanism 30 also includes multiple positioning pins 34, which are all connected to the base 10 and abut against the side wall of the material carrier 31. The multiple positioning pins 34 are used to position the material carrier 31. There can be three, four, six, etc., positioning pins 34. By setting multiple positioning pins 34, a positioning function can be provided when installing the material carrier 31 onto the base 10, which facilitates the installation of the material carrier 31. At the same time, the multiple positioning pins 34 can also provide a limiting function for the material carrier 31, preventing the material carrier 31 from moving during the measurement process and affecting the measurement results.
[0049] The working process of the measuring device 100 provided in this embodiment is roughly as follows:
[0050] First, the handle 215 is rotated around the third direction to push the stop 2123 away from the positioning mechanism 30 in the second direction. Then, the stop 2123 drives the sliding part 2122, the fixed meter head 22, and the gauge 23 away from the positioning mechanism 30 in the second direction to avoid positioning the positioning mechanism 30.
[0051] Then, the positioning handle 325 is rotated around the first direction. The eccentric structure of the positioning handle 325 pushes against the material carrier 31, thereby causing the positioning handle 325 to pull the pusher 322 away from the stop member 33 along the second direction. The pusher 322 drives the push rod 323 to compress the second elastic member 324.
[0052] Next, the workpiece 200 is placed on the carrier 31 and aligned with the stop 33. When positioning the workpiece 200, the positioning handle 325 is rotated in the opposite direction around the first direction. The eccentric structure of the positioning handle 325 rotates away from the carrier 31. The second elastic member 324 pushes the push rod 323 and the push rod 323 moves toward the workpiece 200 along the second direction, thereby pushing the workpiece 200 to the stop 33, thus completing the positioning of the workpiece 200.
[0053] Finally, the push handle 215 is rotated in the opposite direction around the third direction so that the eccentric structure of the push handle 215 rotates away from the stop part 2123. The first elastic element 214 pushes the sliding part 2122 to move towards the positioning mechanism 30 in the second direction, thereby driving the fixed meter head 22 and the measuring meter head 233 to abut against the workpiece 200, so that measurement can be performed.
[0054] When it is necessary to measure other points on the surface to be measured of workpiece 200, the sliding seat 211 can be moved along the first direction to drive the measuring seat 212, the fixed meter head 22 and the meter 23 to move, thereby measuring other points.
