Description

Technical Field

[0001] This utility model relates to the field of inspection tool technology, specifically a movable support inspection tool. Background Technology

[0002] Current technical solutions for dimensional inspection of bracket-type workpieces have significant shortcomings, specifically as follows: First, fixed dedicated inspection fixtures are custom-designed for specific workpieces, have limited functionality, and cannot be adjusted. When inspecting different workpiece models, corresponding dedicated fixtures are required, which not only significantly increases inspection costs but also occupies a large amount of production space. Second, coordinate measuring machines (CMMs), while possessing high measurement accuracy, have slow inspection speeds and are expensive to purchase and maintain. They also have stringent requirements for the inspection environment (such as temperature, humidity, and vibration), making them unsuitable for rapid batch inspection on the production line and difficult to match the production line's pace. Third, manual inspection using general-purpose measuring tools requires operators to use calipers, depth gauges, and other tools to perform multi-point measurements on the workpiece. This is not only inefficient but also prone to human error due to operating techniques and reading interpretations. Furthermore, it requires a high level of operator skill, making it difficult to guarantee the consistency of inspection results. In summary, existing technologies generally suffer from a lack of flexibility (unable to adapt to multiple workpiece models), low inspection efficiency (difficult to achieve rapid batch inspection), low degree of automation (highly dependent on manual operation), and limited functionality (most can only inspect a single type of size), failing to meet the needs of automated production lines for efficient, accurate, and multifunctional workpiece inspection. Utility Model Content

[0003] The purpose of this invention is to provide a movable support fixture that solves the problems of low inspection efficiency and limited functionality of the fixture.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a movable support fixture, comprising a workbench frame, a plastic tabletop fixedly connected to the upper end of the workbench frame, a top cover plate fixedly connected to the top of the workbench frame, an electrical cabinet fixedly installed at the lower end of the top cover plate, the electrical cabinet being fixedly connected to the workbench frame, an emergency stop button provided at the front end of the electrical cabinet, a green illuminated button provided at the front end of the electrical cabinet to the left of the emergency stop button, a selector switch provided at the front end of the electrical cabinet to the left of the green illuminated button, a touch screen provided at the front end of the electrical cabinet above the emergency stop button, the green illuminated button, and the selector switch, a front cover plate fixedly installed on the inner side of the workbench frame and on the back of the plastic tabletop, and a button box provided at the upper end of the workbench frame.

[0005] Preferably, the top of the workbench frame is fixedly equipped with a plurality of evenly distributed feet, and a base plate is fixedly connected above the plurality of feet. A cover is provided below the base plate, and a positioning plate is provided on the top of the base plate. A working disc is rotatably provided on the top of the positioning plate. A plurality of evenly distributed straight toothed pressure plates are provided above the positioning plate. A rotary cylinder is fixedly installed at the upper end of the base plate and inside the positioning plate. A swing arm is fixedly installed at the upper end of the output end of the rotary cylinder, and a paint pen is fixedly installed on the swing arm.

[0006] Preferably, a tri-proof light is fixedly installed at the lower end of the upper cover plate. By designing the tri-proof light, the inspection process of the inspection tool can be indicated.

[0007] Preferably, the bottom of the workbench frame is fixedly connected to multiple evenly distributed connecting plates, and each connecting plate is bolted to a caster. By designing the casters, the entire structure of the support fixture can be moved for operation.

[0008] Preferably, a control switch is provided at the front end of the front cover, and a socket is provided at the front end of the front cover and below the control switch. The control switch allows for the opening and closing of the gauge, while the socket can be used to connect external devices.

[0009] Preferably, a foot switch is provided below the workbench frame, and the foot switch is electrically connected to the electrical cabinet. By designing the foot switch, the operation of the inspection tool can be controlled.

[0010] Preferably, the working disk is equipped with multiple laser sensors that are evenly distributed inside. By designing the laser sensors, non-contact measurement can be achieved, avoiding human error.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through its movable support body (with casters at the bottom) and rotatable worktable, can be quickly moved to different workstations on the production line to adapt to testing needs. Furthermore, by replacing the positioning plate, it can adapt to the testing of different types of workpieces, greatly improving the scene adaptability of the inspection tool and avoiding the high cost problem of "one inspection tool per workpiece" in traditional fixed inspection tools.

[0012] 2. This utility model uses a laser sensor to achieve non-contact measurement, effectively eliminating human error, ensuring accurate and consistent test results, and guaranteeing stable product quality. At the same time, it integrates a pneumatically driven automated testing mechanism, which can start testing with one button after the workpiece is clamped. The testing time for a single piece is greatly shortened, and the skill requirements for operators are low, reducing labor intensity while improving batch testing efficiency.

A touch screen 15 is located at the front end of the electrical cabinet 4 and above the emergency stop button 8, the green illuminated button 9, and the selection switch 14. A control switch 12 is located at the front end of the front cover plate 5 and below the control switch 12. A socket 16 is located at the front end of the front cover plate 5 and below the control switch 12. The control switch 12 can be used to control the opening and closing of the inspection fixture, while the socket 16 can be used to connect external equipment. Multiple evenly distributed connecting plates 6 are fixedly connected to the bottom of the workbench frame 1. Each connecting plate 6 is fixedly mounted with a caster 17 by bolts. The caster 17 can drive the entire structure of the support inspection fixture to move and work. The front cover plate 5 is fixedly installed on the inner side of the workbench frame 1 and on the back of the plastic tabletop 2. A button box 18 is located at the upper end of the workbench frame 1.

[0018] Please see Figure 1 , Figure 2 The workbench frame 1 has multiple evenly distributed feet 19 fixedly installed on its top. A base plate 20 is fixedly connected above the multiple feet 19. A cover 21 is provided below the base plate 20. A positioning plate 22 is provided on the top of the base plate 20. A working disc 23 is rotatably mounted on the top of the positioning plate 22. Multiple evenly distributed straight tooth pressure plates 24 are provided above the positioning plate 22. A rotary cylinder 25 is fixedly installed at the upper end of the base plate 20 and inside the positioning plate 22. A swing arm 26 is fixedly installed at the upper end of the output end of the rotary cylinder 25. A paint pen 27 is fixedly installed on the swing arm 26. Multiple evenly distributed laser sensors 28 are provided inside the working disc 23. By designing the laser sensors 28, non-contact measurement can be achieved to avoid human error.

[0019] The specific implementation process of this utility model is as follows: First, the entire inspection fixture is moved to the designated inspection station on the production line by using the casters 17 at the bottom of the workbench frame 1, and the casters 17 are adjusted to ensure that the inspection fixture is stably parked; at the same time, it is confirmed that the outer cover 21 of the inspection fixture is in a closed state to ensure the safety of the inspection process, and all laser sensors 28 have been fixed to the preset key measurement points by the sensor sheet metal and are in a ready-to-trigger state. Then, the cover 21 is opened, and the workpiece to be tested is placed on the surface of the positioning plate 22 on the worktable 23 of the inspection fixture. The workpiece is then fixed to ensure that it does not shift during the inspection process, thus providing a stable reference for subsequent measurements. After the cover 21 is closed, the inspection control switch 12 is activated. The rotary cylinder 25, which is fixed on the base plate 20, receives the signal and its output shaft drives the swing arm 26, which is fixedly connected to it, to swing around the cylinder shaft. The detection components such as the straight tooth pressure plate 24 installed at the end of the swing arm 26 move with the swing arm 26 and move precisely to the position of the feature to be measured on the workpiece (such as the mounting hole, groove, step surface, etc. of the workpiece). The straight tooth pressure plate 24 can simulate the detection reference surface or trigger the measurement trigger condition of the laser sensor 28. When the straight tooth pressure plate 24 reaches the preset position, the laser sensor 28 corresponding to the feature to be measured is triggered. The laser sensor 28 emits a laser beam to perform non-contact measurement of the dimensional parameters of the feature to be measured on the workpiece. For example, when measuring the depth of the groove, the signal difference formed after the laser beam is reflected is converted into depth data. When measuring the position of the mounting hole, the position error is calculated by the relative deviation between the laser beam and the center of the hole. All measurement data are transmitted to the control system of the fixture in real time. If the workpiece needs to be inspected for features on multiple sides or in different positions, the central rotating shaft of the working plate 23 can be manually or automatically controlled to drive the working plate 23 and the workpiece fixed above it to rotate (the rotation angle is preset according to the position of the feature to be measured), so that the undetected features of the workpiece are rotated into the range of action of the laser sensor 28 and the swing arm 26. Repeat the above detection steps to achieve comprehensive multi-dimensional and multi-station detection of the workpiece. The inspection control system automatically compares the real-time collected measurement data with the preset workpiece size tolerance range. If all measurement parameters are within the tolerance range, the workpiece is deemed qualified. If any parameter exceeds the tolerance, the system immediately issues a non-qualified signal. The non-qualified workpiece can be marked with the paint pen 27 provided with the inspection fixture for easy subsequent sorting. All inspection results (qualified / non-qualified data, specific measurement values) can be output to the display terminal or stored in real time for production traceability.
