[0002] Fixtures are devices used in mechanical manufacturing, machining, and assembly to fix workpieces in the correct position for operation or inspection. Their core function is to ensure machining accuracy, improve production efficiency, and reduce labor intensity. They are indispensable and important process equipment in industrial production. Fixture stroke detection mechanisms are devices used to monitor whether the movement stroke of the fixture during operation meets preset requirements. They are widely used in mechanical manufacturing and automated production lines. Their core function is to ensure the precise opening, closing, and positioning of the fixture, thereby guaranteeing production quality and equipment safety.

[0003] Existing fixture travel detection mechanisms typically use manual clamping to control fixture movement. This not only results in low clamping efficiency but also makes the fixture prone to misalignment or improper control during the detection process, leading to low detection efficiency and certain safety hazards. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing fixture stroke detection mechanisms are usually inefficient and pose significant safety hazards.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A clamp stroke detection mechanism includes a worktable for clamp stroke detection, a clamp assembly for automatic advancement and a detection component for accurate detection of the stroke of the clamp assembly on the worktable, a slide groove for the clamp assembly to slide on the surface of the worktable, a base fixed at the lower end of the worktable, and a sensor sheet matching the detection component on the side of the clamp assembly near the detection component.

[0006] The beneficial effects of this utility model are: by setting up a clamping component controlled by a cylinder, the power for automatic movement of the clamp can be provided, replacing the traditional manual pushing, and achieving one-click clamping with higher efficiency. By setting up a detection component controlled by a PLC for automatic sensing, accurate positioning can be achieved during the movement of the clamp, resulting in better detection effect. The combination of the two components can greatly improve the detection efficiency.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the detection component includes a sensing sensor, a PLC controller, and a reference positioning block.

[0010] Furthermore, mounting holes are provided around the four corners of the lower end of the support frame, and two sets of symmetrically arranged mounting holes are provided on the surface of the second mounting block.

[0011] Furthermore, the clamping assembly includes a clamping module and a cylinder for controlling the clamping module, and the lower end of the clamping module is fixedly connected to a slider that engages and slides with the slide groove.

[0012] Furthermore, the slider has a first connecting block arranged vertically on its side, and a second connecting block arranged horizontally on its side.

[0013] Furthermore, a cylinder is fixedly connected to the end of the second connecting block away from the first connecting block, and two sets of symmetrically arranged support columns are fixedly connected to the lower end of the cylinder.

[0014] Furthermore, a third mounting block is fixedly connected to the lower end of the support column, and mounting holes are opened on the surfaces of the first connecting block, the second connecting block and the third mounting block.

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

In the description of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0025] like Figures 1-5 As shown, a clamp stroke detection mechanism includes a worktable 1 for clamp stroke detection. The worktable 1 is provided with a clamp assembly for automatic advancement and a detection assembly for accurate detection of the clamp assembly stroke. The surface of the worktable 1 is provided with a slide groove 4 for the clamp assembly to slide. A base 5 is fixedly provided at the lower end of the worktable 1. A sensor 6 matching the detection assembly is provided on the side of the clamp assembly near the detection assembly. By providing the sensor 6 matching the detection assembly, accurate positioning of the clamp assembly can be achieved.

[0026] like Figure 3As shown, the detection assembly includes a sensor 201, a PLC controller 202, and a reference positioning block 203. The sensor 201 is correspondingly arranged with the sensing element 6. The sensor 201, PLC controller 202, and reference positioning block 203 are electrically connected to each other via a connecting wire 205. An alarm 204 is provided at the upper end of the PLC controller 202. A first mounting block 206 is fixedly connected to the rear end of the sensor 201. A support frame 207 is provided at the rear end of the first mounting block 206. The sensor 201 is detachably connected to the support frame 207 via the first mounting block 206. Two sets of second mounting blocks 208 are arranged opposite each other on the sides of the reference positioning block 203. Mounting holes are opened around the four corners of the lower end of the support frame 207. Two sets of symmetrically arranged mounting holes are opened on the surface of the second mounting blocks 208.

[0027] like Figures 4-5 As shown, the clamping assembly includes a clamping module 301 and a cylinder 305 for controlling the clamping module 301. The lower end of the clamping module 301 is fixedly connected to a slider 302 that engages and slides with the slide groove 4. The slider 302 has a first connecting block 303 arranged longitudinally on its side and a second connecting block 304 arranged laterally on its side. The cylinder 305 is fixedly connected to the end of the second connecting block 304 away from the first connecting block 303. The lower end of the cylinder 305 is fixedly connected to two sets of symmetrically arranged support columns 306. The lower end of the support columns 306 is fixedly connected to a third mounting block 307. Mounting holes are opened on the surfaces of the first connecting block 303, the second connecting block 304 and the third mounting block 307.

[0028] Working principle:

[0029] First, when the system is started, the cylinder 305 pushes the clamping module 301 to move along the slide 4, the slider 302 ensures the straightness of the movement trajectory, and the first connecting block 303 and the second connecting block 304 transmit the power of the cylinder 305 to the clamping module 301, so that it moves towards the workpiece.

[0030] Then, the sensing plate 6, fixed on the clamping module 301, moves synchronously with the clamping assembly. When the sensing plate 6 approaches the sensing sensor 201, the sensor detects a signal change and transmits the data to the PLC controller 202.

[0031] Next, the PLC controller 202 compares the detected position signal with the preset stroke parameters of the reference positioning block 203. If the position meets the set range, the system continues to run. If it exceeds the tolerance range, the alarm 204 is triggered immediately to prompt the operator to intervene.

[0032] Finally, after positioning is completed, the clamping module 301 performs clamping or releasing actions under the control of the cylinder 305.

[0033] Throughout the process, the support frame 207, the first mounting block 206, the second mounting block 208, and the third mounting block 307 ensure the structural stability of the detection component and the fixture component, while the base 5 provides overall support for the system.

[0034] Note: The first mounting block 206, the second mounting block 208, the third mounting block 307, the first connecting block 303, and the second connecting block 304 are all fixed by bolts, which facilitates disassembly and maintenance; the non-contact detection between the sensing sensor 201 and the sensing plate 6 avoids mechanical wear.

[0035] This fixture stroke detection mechanism, through its innovative structural design and intelligent detection system, achieves high-precision and high-reliability detection and control of the fixture component stroke, offering the following significant advantages:

[0036] Precise positioning and detection

[0037] The non-contact detection by the sensing sensor 201 and the sensing plate 6 avoids the decrease in accuracy caused by mechanical wear, ensuring real-time and accurate feedback of the fixture component position. The coordinated operation of the PLC controller 202 and the reference positioning block 203 can quickly compare the actual stroke with the preset parameters. When the error exceeds the range, the alarm 204 will immediately sound an alarm, effectively preventing machining errors caused by positioning deviations.

[0038] Stable and reliable mechanical structure

[0039] The cooperation between the slide groove 4 and the slider 302 ensures the stability of the linear motion of the clamping assembly, while the linkage design of the first connecting block 303 and the second connecting block 304 optimizes the power transmission efficiency. The modular fixing method of the support frame 207 and each mounting block (first mounting block 206, second mounting block 208, and third mounting block 307) enhances the rigidity of the overall structure and reduces vibration interference.

[0040] Modular design for easy maintenance

[0041] All key components (such as the sensing sensor 201, clamping module 301, cylinder 305, etc.) are fixed by standardized mounting blocks (206 / 208 / 307) and connecting blocks (303 / 304). The bolt connection method makes disassembly, replacement or maintenance more convenient and greatly reduces downtime.

[0042] Automation and intelligent control

[0043] The system uses a PLC controller 202 to automate detection and adjustment, reducing manual intervention and improving production efficiency. Digital processing of the sensed signals enables data traceability, facilitating quality monitoring and process optimization.

[0044] Wide applicability

[0045] This mechanism can be adapted to fixture components of different specifications. By adjusting the parameters of the reference positioning block 203 or changing the position of the sensing plate 6, it can meet diverse production needs and is suitable for various industrial scenarios such as precision machining and automated assembly.

[0046] In summary, this fixture stroke detection mechanism integrates high-precision detection, stable transmission, convenient maintenance, and intelligent control, significantly improving the accuracy of fixture positioning and production efficiency while reducing maintenance costs. It has outstanding practical value and application prospects.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
