[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In order to ensure the quality of workpieces during machining, the flatness of the terminals of the produced workpieces must be checked before packaging, and some workpieces with poor flatness must be removed. Please refer to Figure 1-Figure 6 As shown, this embodiment provides a surface flatness detection device for mechanical processing, including a base 1, two symmetrical support frames 10 are fixedly connected at both ends of the base 1. When the flatness of the workpiece is detected, it is not easy to manually determine the surface flatness of the workpiece, so it is necessary to use a detection device to detect the workpiece. A detection component 3 is fixedly connected between the support frames 10. The detection component 3 is used to detect the surface flatness of the workpiece. The detection component 3 is used to detect the surface flatness of the workpiece to determine whether the workpiece meets the flatness requirement.

[0025] The improvement of this embodiment is that:

[0026] When the flatness of the workpiece is detected, the detection component 3 can intuitively determine the flatness of the workpiece to determine whether the workpiece meets the process effect, and the detection component 3 can mark the uneven parts of the workpiece to facilitate subsequent trimming and retesting of the workpiece.

[0027] Considering that the detection component 3 needs to remain stable when detecting the workpiece, the detection component 3 includes a connecting plate 30, and a plurality of first grooves 301 are evenly opened on the surface of the connecting plate 30. Second grooves 302 are opened at both ends of the first grooves 301. A clamping member 303 is provided inside the second groove 302, and one end of the clamping member 303 is fixedly connected to the bottom of the second groove 302. The detection component 3 also includes a positioning component 31 located in the first groove 301, and the positioning component 31 is between the clamping members 303. When the workpiece is detected, the positioning component 31 is in a moving state, and the positioning component 31 is clamped and fixed by the clamping member 303, so that the positioning component 31 can detect the workpiece more stably and reduce data inaccuracy caused by instability.

[0028] Taking into account that the detection component 3 needs to observe whether the workpiece has achieved the required flatness when inspecting the workpiece, the positioning component 31 includes a vertical rod 310, and two symmetrical connecting columns 311 are fixedly connected at both ends of the interior below the vertical rod 310. The positioning component 31 also includes a punctuation component 312 rotatably connected between the connecting columns 311. When inspecting the workpiece, the punctuation component 312 rotates on the surface of the workpiece. If the surface of the workpiece is uneven, the punctuation component 312 will feed back to the vertical rod 310 to make the vertical rod 310 convex or concave. Manually, only by observing the height of the vertical rod 310, can easily and intuitively judge the workpiece.

[0029] Considering that the flatness detection of the workpiece surface requires the workpiece to be moved to the detection area, the four ends of the base 1 are fixedly connected with connecting frames 2, and the connecting frames 2 are rotatably connected with a conveyor belt 20, wherein the working principle of the conveyor belt 20 is mainly based on the mutual cooperation of friction and tension, specifically: driving device: the power of the conveyor belt 20 comes from the motor. After the motor is started, it drives the reducer to rotate, and the reducer reduces the speed and increases the torque, thereby driving the driving roller to rotate; friction: the driving roller drives the circular rotation of the conveyor belt through friction, which is the key mechanism for the conveyor belt 20 to transport items; tension: the circular rotation of the conveyor belt depends on appropriate tension, which is achieved through the cooperation of the driving device, the middle frame and the rollers; item transportation: the items are placed on the belt or chain, and are continuously and stably transported to the destination under the action of friction and tension; this is easy to understand for people in this technical field, and will not be elaborated on here. The workpiece is brought to the detection area under the action of the conveyor belt 20 so that the workpiece can be inspected and transported.

[0030] Considering that the workpiece is marked after being inspected, so as to facilitate the repair and re-inspection of the workpiece, the punctuation assembly 312 includes a roller 3121, and a plurality of third slots 3122 are evenly opened on the surface of the roller 3121. A four-way tube 3123 is fixedly connected inside the third slot 3122. A telescopic tube 3124 is slidably arranged inside the four ends of the four-way tube 3123. A closing pad 3125 is fixedly connected to one end of the telescopic tube 3124, and one end of the closing pad 3125 is fixedly connected to the opening of the four-way tube 3123. A flip cover 3126 is rotatably connected inside the closing pad 3125. A punctuation tube 3127 is slidably arranged inside the telescopic tube 3124. The punctuation tube 3127 is slidably arranged inside the telescopic tube 3124. One end of the marking tube 3127 is fixedly connected to an elastic member 3128, and the other end of the elastic member 3128 is fixedly connected to the flip cover 3126. When inspecting the workpiece, the roller 3121 rolls on the surface of the workpiece. During the rolling process, if the workpiece is uneven, the marking tube 3127 inside the telescopic tube 3124 will be extended and retracted, and the marking tube 3127 will be extended and retracted so that one end of the marking tube 3127 pushes the flip cover 3126. At this time, a gap is generated between the four-way tube 3123 and the closing pad 3125, so that the marking powder inside the four-way tube 3123 remains on the surface of the workpiece through the groove of the marking tube 3127. By observing the marking powder, it is convenient for manual re-inspection and observation of the workpiece surface.

[0031] In summary, the working principle of this solution is as follows:

[0032] When the surface flatness of the workpiece is detected, the workpiece is placed on the conveyor belt 20, and the workpiece reaches the detection area through the conveyor belt 20. The function of the conveyor belt 20 is to make the roller 3121 roll on the surface of the workpiece. If the surface of the workpiece is uneven, the roller 3121 will be fed back to the vertical rod 310 to make the vertical rod 310 convex or concave. The human only needs to observe the height of the vertical rod 310 to make a very convenient and intuitive judgment of the workpiece; and in the rolling process, if the workpiece is uneven, the marking tube 3127 inside the telescopic tube 3124 will be extended and retracted, and the extension of the marking tube 3127 will cause one end of the marking tube 3127 to push the flip cover 3126, at this time, a gap will be generated between the four-way tube 3123 and the closing pad 3125, so that the marking powder inside the four-way tube 3123 will remain on the surface of the workpiece through the groove of the marking tube 3127, and the surface of the workpiece can be conveniently re-inspected and observed by observing the marking powder.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model.
