Description

Technical Field

[0001] This utility model belongs to the field of machining equipment technology, specifically relating to a workpiece inspection mechanism for machine tools and a machine tool. Background Technology

[0002] In the field of modern machining, machine tools, as the core equipment for achieving precision machining, directly affect the machining quality and production efficiency of workpieces through their machining accuracy and degree of automation. To ensure the stability and consistency of the machining process, it is usually necessary to detect the clamping status of the workpieces mounted on the machine tool, especially to monitor in real time issues such as runout of the workpiece end face, axial position deviation, whether the clamping is in place, or whether there is any eccentricity.

[0003] Traditional workpiece inspection methods often rely on manual contact measurements using tools such as dial indicators. This is not only cumbersome and time-consuming, but also susceptible to human error, making it difficult to meet the demands of automated production lines for efficient and high-precision inspection. Furthermore, failure to detect clamping abnormalities before high-speed workpiece rotation during machining can lead to tool damage, increased machine vibration, or even safety accidents.

[0004] In existing technologies, some machine tools are equipped with automatic detection devices, such as non-contact measurement using fixed sensors in conjunction with rotating workpieces, or position determination using pneumatic or inductive probes. However, these devices are often complex in structure, expensive, and have strict requirements for installation location and environmental cleanliness. At the same time, most detection mechanisms lack sufficient adaptability, making it difficult to continuously and stably acquire information on end-face morphology changes during workpiece rotation, and also unable to accurately convert mechanical displacement into electrical signals that can be recognized by the control system to achieve closed-loop control.

[0005] Especially after a workpiece is clamped by clamping components (such as chucks, collets, etc.), uneven clamping force, workpiece blank errors, or inaccurate clamping positioning often lead to axial runout or tilting of the workpiece end face. If such defects cannot be detected and reported in a timely manner, they will directly affect the accuracy of subsequent machining. Therefore, there is an urgent need for a workpiece inspection mechanism that is simple in structure, highly responsive, can be integrated into a machine tool, and can dynamically detect the end face status during workpiece rotation.

[0006] Furthermore, considering the presence of contaminants such as cutting fluid, metal shavings, and dust in the machine tool's working environment, the testing facility must also possess certain protective capabilities to ensure long-term operational reliability. Simultaneously, the testing facility should be easily adjustable on the machine tool to accommodate workpieces of different lengths, diameters, or clamping methods, thereby improving its versatility and practicality.

[0007] In summary, developing an automatic detection mechanism that can work in conjunction with the machine tool clamping components, detect the end face status of the workpiece in real time during rotation, and feed the detection results back to the control system has become an important technical requirement for improving the intelligence level of machine tools and processing quality. Utility Model Content

[0008] The technical problem to be solved by this utility model is to provide a workpiece inspection mechanism and a machine tool for machine tools, in view of the current state of the prior art.

[0009] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A workpiece inspection mechanism for a machine tool is proposed, wherein a clamping component is rotatably arranged on the machine tool, the clamping component is used to fix the workpiece, and the inspection mechanism includes:

[0010] A fixed base, which is movably mounted on the machine tool;

[0011] A detection rod is movably mounted on the fixed base. One end of the detection rod is used to contact the end of the workpiece clamped on the clamping component, so that when the clamping component drives the workpiece to rotate synchronously, it generates reciprocating motion according to the undulation of the workpiece end face.

[0012] A measuring element is disposed on one side of the detection rod and electrically connected to the control system of the machine tool. The measuring element includes a movable contact, which directly or indirectly abuts against the other end of the detection rod.

[0013] When the clamping component drives the workpiece to rotate synchronously, one end of the detection rod remains in contact with the end of the workpiece, and the movable contact converts the reciprocating motion of the detection rod into a change in the detection signal of the measuring element.

[0014] The aforementioned workpiece inspection mechanism for a machine tool further includes a connecting sleeve fixed on the fixed base, the connecting sleeve including an installation space extending through it along its axial direction, and the inspection rod being movably disposed within the installation space.

[0015] In the above-mentioned workpiece inspection mechanism for machine tools, at least two first mounting brackets are provided on the fixed base, and the at least two first mounting brackets are arranged at intervals along the axial direction of the inspection rod, and the connecting sleeve is fixed on the first mounting bracket.

[0016] In the above-mentioned workpiece inspection mechanism for machine tools, the first mounting bracket includes a first mounting part and a second mounting part. The first mounting part is provided with an elongated through groove. One end of a bolt passes through the through groove and is connected to the fixed seat to fix the first mounting bracket on the fixed seat. One end of the second mounting part is fixed to the first mounting part, and the other end is in contact with the connecting sleeve. An installation space for fixing the connecting sleeve is formed between the first mounting part and the second mounting part.

[0017] In the above-mentioned workpiece inspection mechanism for machine tools, a mounting plate is fixed on the fixed base, the mounting plate is provided with a snap-fit ​​part, and the connecting sleeve is snapped onto the snap-fit ​​part.

[0018] In the above-mentioned workpiece inspection mechanism for machine tools, a second mounting bracket is provided on one side of the fixed base, and the measuring component is fixed on the second mounting bracket.

[0019] In the above-mentioned workpiece inspection mechanism for machine tools, an elastic element is connected to the end of the inspection rod, and the other end of the elastic element is in contact with the movable contact of the measuring element.

[0020] The aforementioned workpiece inspection mechanism for a machine tool further includes a dust cover, which is fitted over the outside of the fixed base, the inspection rod, and the measuring element.

[0021] The aforementioned workpiece inspection mechanism for a machine tool further includes a driving component disposed on the machine tool. The fixed base is disposed at the output end of the driving component. When the driving component is working, it drives the inspection rod to move and abut against the workpiece fixed on the clamping component.

[0022] This utility model also addresses the aforementioned technical problems by providing a machine tool, including the aforementioned workpiece inspection mechanism for a machine tool.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) By setting a movable fixed base, a detection rod that is movably installed on it, and a measuring component that is electrically connected to the control system, the automatic online detection of the end face status of the workpiece after clamping is realized. The structure does not require manual intervention, the detection process is efficient and accurate, and it can effectively identify abnormalities such as workpiece clamping eccentricity, end face runout, tilting or not fully in place, avoiding processing errors, tool damage or even equipment accidents caused by poor clamping, and significantly improving the safety and automation level of the processing process.

[0025] (2) At least two first mounting brackets arranged at intervals along the axial direction of the detection rod are used to fix the connecting sleeve, forming a multi-point support structure, which significantly enhances the installation rigidity and stability of the connecting sleeve and effectively prevents it from loosening or deforming due to vibration or uneven force during long-term use. This design improves the structural strength and anti-interference ability of the entire guide mechanism, further ensures the linearity and accuracy of the detection rod movement, and extends the service life of the detection mechanism.

[0026] (3) By installing a dust cover on the outside of the testing mechanism, contaminants such as cutting fluid, metal shavings, and dust in the machine tool working environment are effectively isolated, preventing them from entering the sliding fit between the testing rod and the connecting sleeve or the inside of the measuring component, thus avoiding problems such as motion jamming, accelerated wear, or sensor failure. This protective structure significantly improves the operational stability and durability of the testing mechanism under harsh working conditions, ensuring long-term reliability.

Detailed Implementation

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0034] like Figures 1 to 4As shown, this utility model discloses a workpiece inspection mechanism for a machine tool. A clamping component 110 is rotatably mounted on the machine tool 100. The clamping component 110 is used to fix the workpiece. The inspection mechanism 200 includes: a fixed base 210, an inspection rod 220, and a measuring component 230.

[0035] Specifically, the fixed base 210 is movably mounted on the machine tool 100; the detection rod 220 is movably mounted on the fixed base 210, and one end of the detection rod 220 is used to contact the end of the workpiece clamped on the clamping member 110, so that when the clamping member 110 drives the workpiece to rotate synchronously, it generates reciprocating motion according to the undulation of the end face of the workpiece; the measuring element 230 is mounted on one side of the detection rod 220 and electrically connected to the control system of the machine tool 100. The measuring element 230 includes a movable contact, which directly or indirectly abuts against the other end of the detection rod 220; when the clamping member 110 drives the workpiece to rotate synchronously, one end of the detection rod 220 remains in contact with the end of the workpiece, and the movable contact converts the reciprocating motion of the detection rod 220 into a change in the detection signal of the measuring element 230.

[0036] The measuring element 230 is a linear displacement sensor, preferably a linear variable differential transformer (LVDT) or a differential inductive displacement sensor; the movable contact is the sensing push rod of the sensor, used to receive the axial displacement transmitted by the detection rod 220 and convert it into a continuous electrical signal output to the machine tool 100 control system, so as to realize real-time monitoring of the workpiece end face runout, clamping eccentricity and other states.

[0037] When the end face of the workpiece in contact with the detection rod 220 is flat, and the workpiece is reliably fixed by the clamping component 110 in a predetermined posture, when the clamping component 110 and the workpiece rotate synchronously under the drive of the machine tool 100, the contact state between the end face of the workpiece and the detection rod 220 remains stable, and the detection rod 220 will not produce obvious axial displacement. At this time, the signal output by the measuring component 230 remains basically constant, or fluctuates within a small allowable range, indicating that the clamping is normal.

[0038] When the end face of the workpiece in contact with the detection rod 220 is uneven, or when the workpiece is clamped in an abnormal posture such as tilting or eccentricity, the undulations of the workpiece end face will drive the detection rod 220 to produce periodic axial reciprocating motion during synchronous rotation. At this time, the signal output by the measuring element 230 will change significantly. The control system collects this signal change in real time, and when it exceeds a preset threshold, it is determined to be a clamping abnormality and automatically triggers an alarm signal, prompting the operator to stop the machine, check, and re-clamp the workpiece.

[0039] This solution achieves automatic online detection of the end face status of the workpiece after clamping by setting up a movable fixed base 210, a detection rod 220 movably mounted on it, and a measuring element 230 electrically connected to the control system. When the clamping component 110 drives the workpiece to rotate synchronously, one end of the detection rod 220 always maintains contact with the end of the workpiece. The slight undulation of the workpiece end face will cause the detection rod 220 to generate axial reciprocating motion. This motion is transmitted to the measuring element 230 through the movable contact and converted into an electrical signal change, which is fed back to the machine tool 100 control system in real time. This structure requires no manual intervention, and the detection process is efficient and accurate. It can effectively identify abnormalities such as workpiece clamping eccentricity, end face runout, tilting, or incomplete positioning, avoiding machining errors, tool damage, or even equipment accidents caused by poor clamping, and significantly improving the safety and automation level of the machining process.

[0040] This solution also includes a connecting sleeve 240 fixed on the fixed base 210. The connecting sleeve 240 includes an installation space extending through it along its axial direction, and the detection rod 220 is movably disposed within the installation space.

[0041] By providing a connecting sleeve 240 with an axially penetrating mounting space on the fixed base 210, and movably placing the detection rod 220 within this space, the movement direction of the detection rod 220 can be effectively guided and constrained, ensuring that it moves only in a straight line along the axial direction and preventing swaying or jamming during the detection process. This structure improves the stability and repeatability of the movement of the detection rod 220, thereby enhancing the reliability and consistency of the overall detection results, while also facilitating the assembly and maintenance of the detection rod 220.

[0042] Furthermore, at least two first mounting brackets 250 are provided on the fixed base 210, and the at least two first mounting brackets 250 are arranged at intervals along the axial direction of the detection rod 220, and the connecting sleeve 240 is fixed on the first mounting brackets 250.

[0043] At least two first mounting brackets 250, spaced apart along the axial direction of the detection rod 220, are used to fix the connecting sleeve 240, forming a multi-point support structure. This significantly enhances the installation rigidity and stability of the connecting sleeve 240, effectively preventing it from loosening or deforming due to vibration or uneven stress during long-term use. This design improves the structural strength and anti-interference capability of the entire guiding mechanism, further ensuring the linearity and accuracy of the movement of the detection rod 220, and extending the service life of the detection mechanism 200.

[0044] The first mounting bracket 250 includes a first mounting part 251 and a second mounting part 252. The first mounting part 251 is provided with an elongated through groove 253. One end of a bolt passes through the through groove 253 and is connected to the fixing seat 210 to fix the first mounting bracket 250 to the fixing seat 210. One end of the second mounting part 252 is fixed to the first mounting part 251, and the other end is in contact with the connecting sleeve 240. An installation space for fixing the connecting sleeve 240 is formed between the first mounting part 251 and the second mounting part 252.

[0045] The elongated through groove 253 on the first mounting part 251 allows the bolts to be adjusted within a certain range, enabling the first mounting bracket 250 to be adjustable on the fixed base 210. The second mounting part 252 abuts against the connecting sleeve 240 and together they form an installation space, allowing the connecting sleeve 240 to be firmly fixed by clamping. This structure not only facilitates the quick installation and removal of the connecting sleeve 240, but also supports fine-tuning positioning, ensuring that the axis of the connecting sleeve 240 is aligned with the axis of the workpiece, improving the assembly accuracy and adaptability of the detection mechanism 200, and contributing to improved detection accuracy.

[0046] A mounting plate 260 is fixed on the mounting base 210. The mounting plate 260 is provided with a snap-fit ​​part, and the connecting sleeve 240 is snapped onto the snap-fit ​​part.

[0047] By setting a mounting plate 260 with a snap-fit ​​part on the fixed base 210 and snapping the connecting sleeve 240 into it, the quick and convenient installation and positioning of the connecting sleeve 240 is achieved. This snap-fit ​​structure can achieve a stable connection without additional fasteners, simplifying the assembly process and reducing maintenance costs, while still ensuring sufficient connection strength and positioning accuracy, making it suitable for production scenarios that require frequent adjustment or replacement of detection components.

[0048] A second mounting bracket 270 is provided on one side of the fixed base 210, and the measuring component 230 is fixed on the second mounting bracket 270.

[0049] By setting a second mounting bracket 270 on the fixed base 210 and fixing the measuring element 230 thereon, a stable relative position relationship is maintained between the measuring element 230 and the detection rod 220, avoiding the influence of external vibration or movement on the signal acquisition accuracy caused by the displacement of the measuring element 230. This structure has a reasonable layout, high space utilization, and is easy to integrate into the machine tool 100. It also facilitates later debugging and replacement, improving the stability and maintainability of the detection system.

[0050] An elastic element is connected to the end of the detection rod 220, and the other end of the elastic element is in contact with the movable contact of the measuring element 230.

[0051] An elastic element (preferably a spring) is provided between the movable contact of the detection rod 220 and the measuring element 230. This provides a constant preload during the detection process, ensuring that the detection rod 220 maintains good contact with the workpiece end face at all times. Even when there are slight undulations or vibrations on the workpiece end face, continuous and stable signal transmission can be achieved. At the same time, the elastic element acts as a buffer, reducing damage to the measuring element 230 from rigid impacts, protecting the precision sensing components, extending the service life of the equipment, and improving the sensitivity and reliability of the detection.

[0052] This solution also includes a dust cover 280, which is fitted over the outside of the mounting base 210, the detection rod 220 and the measuring element 230.

[0053] By installing a dust cover 280 on the outside of the detection mechanism 200, contaminants such as cutting fluid, metal shavings, and dust in the working environment of the machine tool 100 are effectively isolated, preventing them from entering the sliding fit between the detection rod 220 and the connecting sleeve 240 or the interior of the measuring component 230, thus avoiding problems such as movement jamming, accelerated wear, or sensor failure. This protective structure significantly improves the operational stability and durability of the detection mechanism 200 under harsh working conditions, ensuring long-term reliability.

[0054] This solution also includes a drive unit 300, which is mounted on the machine tool 100, and a fixed base 210 is connected to the output end of the drive unit 300. When the drive unit 300 is working, it drives the detection rod 220 to move, so that it contacts or separates from the end of the workpiece fixed on the clamping component 110.

[0055] The driving component 300 can be a pneumatic cylinder, an electric push rod, or a servo linear actuator, preferably a pneumatic cylinder or a servo feed slide mounted on the machine tool 100. Its output end is connected to the fixed base 210, and it can automatically drive the detection mechanism 200 to move in a predetermined direction under the command of the control system, so as to achieve reliable contact and safe retraction between the detection rod 220 and the end of the workpiece, thereby completing the automatic detection of the workpiece clamping state.

[0056] By setting up a driving component 300 and connecting the fixed base 210 to its output end, the feed and retraction actions of the detection mechanism 200 can be automatically controlled, realizing the automatic contact and separation between the detection rod 220 and the end of the workpiece. This design achieves full automation of the detection process without manual intervention, significantly improving detection efficiency, and is especially suitable for automated production lines or unmanned processing units. Furthermore, the initial position and feed stroke of the detection mechanism 200 can be flexibly adjusted according to the size and clamping position of different workpieces, further enhancing the versatility and adaptability of the detection system.

[0057] This solution also proposes a machine tool 100, which includes the aforementioned testing mechanism 200.

[0058] This solution provides a workpiece inspection mechanism 200 for a machine tool 100 and the machine tool 100 itself, aiming to solve the problems of low efficiency, poor accuracy, and insufficient automation in workpiece clamping status detection in the prior art. The inspection mechanism 200, through the inclusion of a movable fixed base 210, a guideable moving detection rod 220, and a measuring element 230 electrically connected to the control system, achieves real-time, dynamic online detection of the end face status of the workpiece during clamping and synchronous rotation by the clamping component 110. When there are undulations or eccentricities on the workpiece end face, the detection rod 220 generates axial reciprocating motion, and transmits the displacement to the measuring element 230 through a movable contact, converting it into an electrical signal change that can be recognized by the control system, thereby accurately determining the clamping quality of the workpiece.

[0059] To further improve detection accuracy and structural stability, this solution also includes a connecting sleeve 240 to guide the detection rod 220. A first mounting bracket 250 or mounting plate 260 ensures the stable installation of the connecting sleeve 240, and a second mounting bracket 270 fixes the measuring component 230, ensuring reliable relative positioning of all components. An elastic element ensures constant contact force and cushions impacts during the detection process. A dust cover 280 effectively protects against cutting fluid and dust, and the drive component 300 automates the detection action, significantly improving the system's intelligence and adaptability.

[0060] The measuring element 230 is preferably a high-precision linear sensor such as an LVDT displacement sensor or an inductive probe, which can convert minute displacements into continuous electrical signals to meet the requirements of precision detection; alternatively, a limit switch can be used to realize basic position judgment, taking into account both cost and reliability.

[0061] In summary, this solution has a reasonable structure, sensitive response, and stable operation. It integrates guiding, transmission, measurement, protection, and automatic control functions into one, and can be widely used in various CNC machine tools 100. It realizes automatic identification and safety interlock of workpiece clamping status, effectively prevents machining errors, tool damage, or even equipment accidents caused by improper clamping, and significantly improves the automation level, machining accuracy, and operational safety of machine tools 100.
