Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and more specifically, to a testing fixture and a cutting device. Background Technology

[0002] In the current field of cutting equipment, after the workpiece is attached to the workpiece plate, it is placed on the worktable for cutting. For equipment with multiple worktables, or for multiple machines, the worktable of the cutting equipment is assembled from multiple parts, and it inherently has unavoidable processing and assembly errors, leading to instability in the worktable's reference position. Therefore, if the workpiece plate is directly installed based on the worktable reference, it is impossible to ensure consistent positioning accuracy of the workpiece plate on different machines. This not only affects production efficiency but may also lead to fluctuations in cutting quality.

[0003] Therefore, to solve the above problems, it is necessary to maintain consistent or within a certain range the positional relationship between multiple worktable references and their corresponding equipment references, ensuring consistent positioning accuracy of the workpiece plate on different worktables. Then, the workpiece plate can be installed using the worktable references, improving production efficiency and product quality. Current technologies rely on manual measurement and calibration, a process that is not only time-consuming but also susceptible to operator skill levels, making it difficult to achieve the desired accuracy. Therefore, there is an urgent need for a detection fixture capable of accurately detecting the positional relationship between the worktable references and the equipment references. Utility Model Content

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] like Figures 1 to 8 As shown, one embodiment of this utility model provides a detection fixture applied to a cutting device. The cutting device includes a device reference 10 and at least two worktable references 20. The cutting device also includes at least two spaced-apart worktables 30, each of which is movably arranged. The at least two worktable references 20 are arranged in a one-to-one correspondence with the at least two worktables 30. Figure 1As shown, the equipment reference 10 here refers to the positioning reference surface of the cutting equipment, and multiple devices rely on the equipment reference 10 to achieve a unified position. In this embodiment, the equipment reference 10 serves as a fixed reference for calibrating and detecting the position of the worktable reference 20. The worktable reference 20 here refers to the zero-point reference for placing the workpiece plate. When processing on multiple devices or multiple worktables 30 of the same device, ensuring the positional consistency between each worktable reference 20 and its corresponding equipment reference 10 is crucial. If there is a deviation in the position of these worktable references 20, even under the same program control, the processing results on different worktables 30 will differ, which may lead to unstable product quality, non-interchangeability of workpieces, increased production costs, and reduced efficiency. Specifically, in the cutting equipment, if the worktable 30 is not correctly aligned with the worktable reference 20, the position of the workpiece may deviate from the expected position during the cutting process, resulting in inaccurate cutting dimensions or damage to the workpiece.

[0046] To address the aforementioned issues, the testing fixture provided in this embodiment includes a fixed plate 1, at least two testing plates 2, and a testing element 3. The fixed plate 1 is disposed on the equipment reference 10, and the fixed plate 1 is parallel to the equipment reference 10. At least two testing plates 2 are disposed on the fixed plate 1, and the at least two testing plates 2 are spaced apart along the length direction of the fixed plate 1. The at least two testing plates 2 are disposed in a one-to-one correspondence with at least two worktable references 20. The testing element 3 is detachably connected to the fixed plate 1. The testing fixture has a first adjustment state and a testing state. When the testing fixture is in the first adjustment state, the testing element 3 is independent of the fixed plate 1, and the worktable 30 is adjusted to a first height position so that the testing plate 2 and the worktable reference 20 are in contact with each other. When the testing fixture is in the testing state, the testing element 3 is installed on the fixed plate 1, and the worktable 30 is adjusted to a second height position so that the worktable 30 and the worktable reference 20 avoid the testing plate 2, and the testing end of the testing element 3 is positioned towards the testing plate 2.

[0047] The fixed plate 1 provides a stable foundation for supporting and positioning the detection plate 2 and the detection component 3. When the detection fixture is in its first adjustment state, the detection plate 2, by engaging with the worktable reference 20, helps adjust the position of the worktable reference 20 to align with or within the allowable deviation range of the equipment reference 10. The detection component 3 is detachably connected to the fixed plate 1. Its function is to accurately measure the positional relationship between the worktable reference 20 and the equipment reference 10 when the detection fixture is in the detection state. By aligning the detection end of the detection component 3 with the detection plate 2, precise positional information between the two can be obtained, thereby determining whether the position of the worktable reference 20 meets the requirements. Using this detection fixture, the worktable references 20 on multiple machines or multiple worktables 30 on the same machine can be precisely adjusted to the same or similar positions. This ensures that the workpiece plate does not need to be repositioned when processed on different worktables 30, ensuring the positional accuracy of the worktable reference 20 relative to the equipment reference 10, thus achieving workpiece consistency and interchangeability on multiple machines or different worktables 30 of the same machine. It improves processing efficiency and workpiece plate utilization, and reduces changeover time and cost between equipment.

[0048] Specifically, the detection component 3 is a dial indicator, and the worktable reference 20 includes a first reference surface 201 and a second reference surface 202 spaced apart along a predetermined direction. The dial indicator has a first working state and a second working state. When the dial indicator is in the first working state, its detection end contacts the first reference surface 201; when the dial indicator is in the second working state, its detection end contacts the second reference surface 202. The predetermined direction here refers to the length direction of the cutting equipment. Both the first and second working states of the dial indicator are performed within the aforementioned detection state, where the dial indicator is used to detect minute positional deviations between the worktable reference 20 and the equipment reference 10. When the dial indicator is in the first working state, its detection end contacts the first reference surface 201. At this time, the dial indicator can measure the positional deviation of the first reference surface 201 relative to the fixed plate 1 (i.e., the plane parallel to the equipment reference 10). When the dial indicator is in the second working state, its detection end contacts the second reference surface 202. At this point, the dial indicator can measure the positional deviation of the second reference surface 202 relative to the detection plate 2 (i.e., the plane parallel to the equipment reference 10). By taking measurements on the first reference surface 201 and the second reference surface 202 respectively, the inspection fixture can verify the accuracy of the worktable reference 20 at different positions, ensuring the stable positioning of the workpiece during processing. The inspection fixture, through precise measurements on different reference surfaces using a dial indicator, effectively improves the accuracy and reliability of the worktable reference 20 adjustment.

[0049] For example, a cutting device with two worktables 30 will be used as an example, and the two worktables 30 move in the same way. Figure 1 and Figure 7 As shown, when testing the positional relationship between the equipment reference 10 and the worktable reference 20, the worktable 30 can be adjusted to fit against the worktable reference 20 first, and then the worktable 30 can be adjusted to the first height position so that the worktable reference 20 and the detection plate 2 fit together, i.e., the testing fixture is in the first adjustment state. Then, the worktable 30 can be adjusted to the second height position so that both the worktable reference 20 and the worktable 30 avoid the detection plate 2. The detection component 3 is then installed, and the detection component 3 sequentially tests the first reference surface 201 and the second reference surface 202. When the dial indicator is in the first working state, the dial indicator tests the values ​​of at least three points on the first reference surface 201. If the test results show that the above values ​​are almost the same (or within the allowable error range), it indicates that the positional relationship between the first reference surface 201 and the equipment reference 10 is qualified. If the test results show that the above values ​​differ significantly (exceeding the allowable error range), it indicates that the positional relationship between the first reference surface 201 and the equipment reference 10 is unqualified, and the position of the first reference surface 201 needs to be adjusted, including adjustment along the horizontal direction and adjustment of the tilt angle. When the dial indicator is in its second working state, it measures the values ​​at at least three points on the second reference surface 202. If the values ​​measured on the second reference surface 202 are almost the same as those measured on the first reference surface 201 (or within the allowable error range), it indicates that the position of the second reference surface 202 relative to the first reference surface 201 is acceptable. If the values ​​measured on the second reference surface 202 differ significantly from those measured on the first reference surface 201 (exceeding the allowable error range), it indicates that the position of the second reference surface 202 needs to be adjusted, including adjustments along the horizontal direction and adjustments to the tilt angle.

[0050] In cases where high positional accuracy is not required, the testing component 3 can be set as a dial indicator.

[0051] Furthermore, such as Figure 7As shown, the dial indicator has a third working state. When the dial indicator is in the third working state, it is positioned between two adjacent worktables 30. After the dial indicator's sensing end contacts the first worktable reference 20 and before it contacts the second worktable reference 20, the dial indicator remains between the two adjacent worktables 30 to prevent collisions between the dial indicator and the worktables 30. For example, a cutting device with two worktables 30 is used as an example, and the movement of the two worktables 30 has a sequential order. When inspecting the positional relationship between equipment reference 10 and workbench reference 20, one of the workbenches 30 can be adjusted to align with its corresponding workbench reference 20. Then, the workbench 30 is adjusted to a first height position, so that the workbench reference 20 and the inspection plate 2 are aligned, i.e., the inspection fixture is in its first adjustment state. Next, the workbench 30 is adjusted to a second height position, so that both the workbench reference 20 and the workbench 30 avoid the inspection plate 2. Then, the inspection component 3 is installed, and the inspection component 3 inspects the base of the workbench 30 corresponding to the workbench 30. Subsequently, [the process continues]. The table is adjusted to the space between the two worktables 30. Further, the other worktable 30 is adjusted to fit with its corresponding worktable reference 20. Then, the other worktable 30 is adjusted to the first height position so that the worktable reference 20 and the detection plate 2 fit together, that is, the detection fixture is in the first adjustment state. Then, the other worktable 30 is adjusted to the second height position so that both the worktable reference 20 and the other worktable 30 avoid the detection plate 2. The position of the detection piece 3 is adjusted so that it switches from the third working state to the second working state to detect the second reference surface 202.

[0052] Furthermore, the testing fixture includes a position moving component 4, at least a portion of which is movably mounted on the fixed plate 1 to drive the dial indicator to switch between the first working state, the second working state, and the third working state. The position moving component 4 includes a guide rail 41 and a slider 42. The guide rail 41 is fixedly connected to the fixed plate 1, and the length direction of the guide rail 41 is parallel to the length direction of the fixed plate 1. The slider 42 is slidably mounted on the guide rail 41, and the dial indicator is mounted on the slider 42. The guide rail 41 guides the slider 42 to move along a predetermined path, thereby driving the dial indicator to the various positions required for testing. This allows the dial indicator to flexibly switch between different working states, reducing the number of manual adjustments and saving testing and adjustment time.

[0053] Furthermore, the dial indicator and the slider 42 are detachably connected; exemplarily, the dial indicator and the slider 42 are connected via a magnetic attraction structure. Because the dial indicator and the slider 42 are connected by a magnetic attraction structure, the assembly and disassembly of the dial indicator becomes simple and quick, facilitating regular cleaning and maintenance. The magnetic attraction structure not only provides quick installation and disassembly of the dial indicator but also simplifies the operator's workflow. Especially for scenarios requiring frequent adjustments to the testing status or replacement of the dial indicator, the convenience of the magnetic connection significantly improves operational efficiency.

[0054] For example, such as Figure 6 As shown, the testing fixture includes a mounting component 5, which comprises a base 51 and a connecting rod 52. The base 51 is mounted on the slider 42, and the two ends of the connecting rod 52 are respectively connected to the base 51 and the dial indicator. When installing the dial indicator, the base 51 and the slider 42 are detachably connected, and the connection between the base 51 and the dial indicator is achieved through the connecting rod 52, facilitating adjustment of the dial indicator's position according to actual needs.

[0055] Furthermore, the detection plate 2 and the fixing plate 1 can be integrally formed or detachably connected. The detachable design makes maintenance and cleaning of the detection plate 2 more convenient. During the testing process, dust and other impurities may accumulate on the detection plate 2, affecting the accuracy of the test. With the detachable connection, the detection plate 2 can be quickly removed for cleaning or replacement, ensuring that each test is performed under clean, interference-free conditions, thereby maintaining the accuracy of the test. At the same time, when the detection plate 2 becomes worn or damaged, the cost of replacing the detection plate 2 is far lower than the cost of replacing the entire testing fixture.

[0056] For example, such as Figure 3 and Figure 4 As shown, the detection plate 2 includes a first plate body 21 and a second plate body 22 connected to each other. The first plate body 21 is detachably connected to the fixed plate 1, and the second plate body 22 is used to fit against the worktable reference 20. The roughness of the first plate body 21 is greater than that of the second plate body 22. The second plate body 22, which fits against the worktable reference 20, adopts a lower roughness design, which ensures a more stable and precise contact surface during contact. The low-roughness surface helps to reduce small gaps or irregularities between the contact surfaces, thereby improving the sensitivity and accuracy of the dial indicator during detection and ensuring more reliable measurement results. Compared with the second plate body 22, the first plate body 21 has a higher roughness. Higher roughness usually means stronger wear resistance. As the part connected to the fixed plate 1, the first plate body 21 may be subjected to more mechanical stress. High roughness can improve its durability and extend the service life of the detection plate 2. Exemplarily, the connection method of the first plate body 21 and the second plate body 22 can be a threaded connection, a snap-fit ​​structure, etc.

[0057] In other possible embodiments, the detection plate 2 is integrally formed.

[0058] Furthermore, the testing fixture includes a feeler gauge, such as... Figure 8 As shown, the testing fixture has a second adjustment state. When the testing fixture is in the second adjustment state, the worktable 30 is in contact with the worktable reference 20, and the feeler gauge is used to detect the distance between the testing plate 2 and the worktable reference 20. A feeler gauge is a precision tool used to measure minute gaps, and its thickness is usually available in various specifications. When the testing fixture is in the second adjustment state, the worktable 30 is in contact with the worktable reference 20. At this time, the feeler gauge is inserted between the testing plate 2 and the worktable reference 20, and the distance or gap between them can be accurately measured. For cases where the testing accuracy requirement is general, the positional relationship between the equipment reference 10 and the worktable reference 20 can be detected using a feeler gauge. For cases where the testing accuracy requirement is high, a coarse inspection can be performed first using a feeler gauge, and the position of the worktable reference 20 can be adjusted accordingly. Then, a dial indicator can be used to perform a fine inspection on the first reference surface 201 and the second reference surface 202.

[0059] Furthermore, the fixing plate 1 is provided with at least one weight-reducing hole 11, which can significantly reduce the overall weight of the testing fixture while maintaining its structural strength. For example, at least one weight-reducing hole 11 is provided at intervals along the length of the fixing plate 1. The shape and size of each weight-reducing hole 11 can be designed according to actual conditions; for example, each weight-reducing hole 11 can be circular, polygonal, annular, etc.

[0060] The inspection fixture is used to precisely position the worktable 30 relative to the equipment, ensuring the consistency and interchangeability of the workpiece plate during processing on different machines. Its working process is detailed below:

[0061] First, the fixing plate 1 is placed on the equipment reference 10, ensuring that the two are parallel. Then, at least two detection plates 2 are installed on the fixing plate 1, spaced apart along the length of the fixing plate 1 and corresponding one-to-one with the corresponding worktable reference 20. Entering the first adjustment state, the worktable 30 is adjusted to the first height position, so that each detection plate 2 can be in contact with its corresponding worktable reference 20. Next, the detection fixture is switched to the detection state. At this time, the worktable 30 is adjusted to the second height position to prevent the worktable 30 and worktable reference 20 from contacting the detection plates 2. The detection element 3 is then installed on the fixing plate 1, ensuring that the detection end of the detection element 3 faces the detection plate 2. In this state, the dial indicator, as the detection element 3, enters the first working state and the second working state successively, that is, its detection end contacts the first reference surface 201 and the second reference surface 202 respectively, completing the precise measurement of the position of the worktable reference 20. In some cases, the dial indicator may need to enter a third working state, in which case it is located between two adjacent worktables 30. The dial indicator switches between the first working state, the second working state, and the third working state through the adjustment of the position moving component 4.

[0062] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0063] By using this inspection fixture, the worktable reference 20 on multiple devices or multiple worktables 30 on the same device can be precisely adjusted to the same or similar positions. This ensures that the workpiece plate does not need to be repositioned when it is processed on different worktables 30, and ensures the positional accuracy of the worktable reference 20 relative to the device reference 10, thereby achieving consistency and interchangeability of workpieces on multiple devices or different worktables 30 of the same device.

[0064] Another embodiment of this utility model provides a cutting device including the aforementioned inspection fixture. The cutting device includes a base 60 and at least one bearing housing 40. The base 60 has mounting holes 50, and the bearing housing 40 is mounted in the mounting holes 50. The device reference 10 is formed around the mounting holes 50. The fixing plate 1 of the inspection fixture is designed to match the mounting holes 50 of the base 60, enabling the inspection fixture to be quickly positioned and accurately measure the relative position between the worktable reference 20 and the device reference 10. This ensures the efficient use of the inspection fixture and reduces preparation time and operational complexity before inspection.
