Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of screw processing, and in particular to an adjustable screw size efficient automatic detection device. Background Art
[0002] Screws are a familiar piece of hardware with a wide range of applications. Therefore, screw quality is of paramount importance to manufacturers, including testing screw head parameters such as appearance, thickness, and diameter. To ensure screw quality, random sampling of screws processed by thread rolling machines is typically performed. The screw head parameters are then manually measured with a vernier caliper to determine whether they meet specifications.
[0003] However, during the sampling inspection process, workers are usually required to sample one by one and manually operate the vernier caliper to complete the positioning, measurement, and recording steps, which is a cumbersome operation. At the same time, when using the vernier caliper to inspect the screw head, the screw head needs to be manually clamped. If the force is too great, the screw surface will be damaged, and if the force is too small, the measurement position will be offset, affecting the accuracy of the test results, which is inconvenient to use. Summary of the Invention
[0004] In view of this, the present invention provides an adjustable screw size efficient automatic detection device, which has a sensor body that can conveniently and quickly detect the screw size. By toggling the knob adjustment handle, the fixation of the connecting slider is released. At this time, the knob adjustment handle can be used to drive the connecting slider to slide in the position adjustment groove. As the connecting slider slides, the connecting slider is adjusted back and forth. After the connecting slider is adjusted back and forth, if the sensor body and the screw body to be measured are misaligned, the adjustment seat can be rotated to rotate the adjustment seat and adjust the position of the sensor body. Then, the servo electric cylinder is started to drive the servo electric cylinder to drive the second movable plate to move. At the same time, as the second movable plate moves, the first movable plate will be driven to move. During the movement of the first movable plate, the guide slider will be driven to move, and as the guide slider moves, it will slide along the guide rail. Then, the cooperation of the guide slider and the guide rail can provide guidance for the movement of the second movable plate, ensuring the stable movement of the second movable plate. Through the movement of the second movable plate, the sensor body is automatically moved to the relative position to efficiently detect the screw size.
[0005] The present invention provides an adjustable screw size efficient automatic detection device, which specifically includes: a fixed base; a thread rolling machine base is provided at the lower part of the fixed base; the right part of the top surface of the fixed base is fixedly connected to a support base; the right end surface of the support base is fixedly connected to a first mounting base; the first mounting base is fastened to the top surface of the fixed base by bolts; a second mounting base is fastened to the left part of the top surface of the fixed base by bolts; the position of the second mounting base is aligned with the first mounting base; a servo electric cylinder is fastened to the top surface of the support base by bolts; a second movable plate is fixedly connected to the lower part of the output shaft of the servo electric cylinder by bolts; the second movable plate is slidably connected in the support base.
[0006] Furthermore, a first movable plate is fixedly connected to the left portion of the top surface of the second movable plate; the first movable plate is arranged on the right side of the second mounting seat.
[0007] Furthermore, the left end surface of the first movable plate is fixedly connected to a guide slider; the right end surface of the second mounting seat is fixedly connected to a guide rail; the guide slider is aligned with the guide rail; and the guide slider is slidably connected to the guide rail.
[0008] Furthermore, a position adjustment groove is provided on the top surface of the second movable plate; the position adjustment groove is a rectangular groove structure; a connecting slider is slidably connected in the position adjustment groove; and a knob adjustment handle is provided on the top surface of the connecting slider.
[0009] Furthermore, the bottom end surface of the connecting slider is fixedly connected with a mounting screw; the lower part of the mounting screw is threadedly connected with an adjusting seat.
[0010] Furthermore, a sensor body is provided in the adjustment seat; a screw body to be measured is provided below the sensor body; and the positions of the sensor body and the screw body to be measured are aligned.
[0011] The present invention provides an adjustable screw size efficient automatic detection device, which has the following beneficial effects: When the present invention detects the screw size, the connection slider is released by turning the knob adjustment handle. At this time, the connection slider can be driven to slide in the position adjustment groove by the knob adjustment handle to adjust the connection slider back and forth so that the position of the sensor body and the screw body to be measured are aligned. If the sensor body and the screw body to be measured are misaligned after the back and forth adjustment, the adjustment seat can be rotated to rotate the adjustment seat and adjust the position of the sensor body to adapt to various thread rolling machines with different assembly structures. It also makes the position of the new type installed on the thread rolling machine base relatively unrestricted. By starting the servo electric cylinder to move the first movable plate, the sensor body is aligned with the screw body to be measured. The main body automatically moves to a relative position so that it can detect the distance between the sensor and the screw body to be tested. At the same time, a floating value can be set on the human-machine panel of the thread rolling machine to enable the sensor to determine whether the position of each bolt passing through is abnormal, and to remove the screw body with abnormal position. At the same time, the distance detection signal of the sensor body can also be used by the control unit to analyze and judge the flatness and appearance of the top surface of the head of the screw body to be tested, so as to detect whether there are any defects in the appearance of the head of the screw body to be tested. The operation is simple and fast, which reduces the labor intensity of the staff and improves the accuracy of screw size detection, thereby effectively improving the practicality and convenience of the high-efficiency automatic detection device for screw size.

[0023] The present invention provides an adjustable screw size efficient automatic detection device, please refer to Figures 1 to 8 As shown, it includes: a fixed base 1; A thread rolling machine base 115 is provided at the lower part of the fixed base 1; a support base 101 is fixedly connected to the right part of the top surface of the fixed base 1; a first mounting base 102 is fixedly connected to the right end surface of the support base 101; the first mounting base 102 is fastened to the top surface of the fixed base 1 by bolts; a second mounting base 103 is fastened to the left part of the top surface of the fixed base 1 by bolts; the second mounting base 103 is aligned with the first mounting base 102; a servo electric cylinder 113 is fastened to the top surface of the support base 101 by bolts; a second movable plate 107 is fixedly connected to the lower part of the output shaft of the servo electric cylinder 113 by bolts; the second movable plate 107 is slidably connected in the support base 101.
[0024] The left portion of the top surface of the second movable plate 107 is fixedly connected with a first movable plate 106 ; the first movable plate 106 is arranged on the right side of the second mounting seat 103 .
[0025] Among them, the left end face of the first movable plate 106 is fixedly connected to a guide slider 105; the right end face of the second mounting seat 103 is fixedly connected to a guide rail 104; the guide slider 105 is aligned with the guide rail 104; the guide slider 105 is slidably connected to the guide rail 104.
[0026] Among them, a position adjustment groove 108 is opened on the top surface of the second movable plate 107; the position adjustment groove 108 is a rectangular groove structure; a connecting slider 116 is slidably connected in the position adjustment groove 108; and a knob adjustment handle 109 is set on the top surface of the connecting slider 116.
[0027] The bottom end surface of the connecting slider 116 is fixedly connected to a mounting screw 110 ; the lower portion of the mounting screw 110 is threadedly connected to an adjustment seat 111 .
[0028] Specific usage and function of this embodiment: In the present invention, the screw size efficient automatic detection device is installed on the thread rolling machine base 115 through the fixed base 1. When performing the detection, the servo electric cylinder 113 is started to drive the second movable plate 107 to move. At the same time, the movement of the second movable plate 107 will drive the first movable plate 106 to move. In the process of the movement of the first movable plate 106, the guide slider 105 will be driven to move, and the movement of the guide slider 105 will make it slide along the guide rail 104. Then, the cooperation between the guide slider 105 and the guide rail 104 can provide guidance for the movement of the second movable plate 107, thereby ensuring the stable movement of the second movable plate 107. The sliding cooperation between the guide slider 105 and the guide rail 104 is a precision machined part. The fitting clearance is ≤0.05mm (conventional accuracy in this field), and the guide rail 104 is fixed to the second mounting seat 103, and the perpendicularity tolerance with respect to the plane of the fixed base 1 is ≤0.02mm, which structurally ensures the straightness of the moving trajectory of the sensor body 112, and the screw size is efficiently detected by the movement of the second movable plate 107. By turning the knob adjustment handle 109, the fixation of the connecting slider 116 is released. Only then can the knob adjustment handle 109 be used to drive the connecting slider 116 to slide in the position adjustment groove 108, and the connecting slider 116 is adjusted back and forth as the connecting slider 116 slides. The position adjustment groove 108 is a rectangular groove structure, and its length direction is parallel to the guide rail 104, limiting the connecting slider 116 to move only in the front and back direction (i.e., the sensor detection direction) to avoid left and right deviation. After the knob adjustment handle 109 is tightened, the connecting slider 116 is fixed in the groove by friction. The locking accuracy can ensure that the vertical deviation of the mounting screw 110 and the plane of the fixed base 1 is ≤0.1°. The core principle of the knob adjustment handle 109 is to fix the component in a specific position by tightening or loosening the knob and using a thread or a clamping mechanism. It is a knob adjustment handle 109 that integrates manual adjustment and locking. Its principle is the same as that of the locking knob. Since the principle of locking and screwing is a common technical means used by those skilled in the art, it will not be described in detail here. Before and after the connecting slider 116 is tightened, the connecting slider 116 is tightened. After the adjustment, if the sensor body 112 and the screw body 114 to be measured are misaligned, the adjustment seat 111 can be rotated to rotate the adjustment seat 111 and adjust the position of the sensor body 112. The threads of the mounting screw 110 and the adjustment seat 111 are matched with fine threads (a conventional design in this field) and have a self-locking function. When the connecting slider 116 moves in the position adjustment groove 108, the guiding effect of the thread pair will automatically compensate for small angular deviations to ensure that the adjustment seat 111 is vertically downward and the detection axis of the sensor body 112 is consistent with the movement direction of the guide rail 104. Example
[0029] Based on Example 1, please refer to Figure 1 and Figure 8 As shown, it includes: a sensor body 112 and a screw body 114 to be measured, a sensor body 112 is set in the adjustment seat 111; the screw body 114 to be measured is set at the lower part of the sensor body 112; the positions of the sensor body 112 and the screw body 114 to be measured are aligned.
[0030] The specific usage and function of this embodiment: In the present invention, after the position adjustment of the sensor body 112 is completed, the sensor body 112 is aligned with the head position of the screw body 114 to be measured, and then automatically moves to the relative position for detection through the movement of the second movable plate 107. The sensor body 112 signal is connected to a control unit, such as but not limited to the main console of the thread rolling machine, or a microprocessor with a computing function. Since the control unit is a technical means commonly used by those skilled in the art, it is not shown in detail in the figure. The sensor body 112 is a laser rangefinder that can detect the distance between it and the head of the screw body 114 to be measured and generate a distance detection signal, which is transmitted to the control unit. The control unit can detect the distance between it and the head of the screw body 114 to be measured according to a pre-measured reference distance (that is, the sensor body 1 12 and the plane carrying the screw body 114 to be tested), and the difference between the measured distances obtained by analyzing the distance detection signal, and calculating whether the current state of the screw body 114 to be tested meets the production technical requirements. At the same time, a floating value can be set on the human-machine panel of the thread rolling machine to enable the sensor to determine whether there is any position abnormality in each bolt passing through, and to remove the screw body with abnormal position. In addition, the distance detection signal of the sensor body 112 can also be used by the control unit to analyze and determine the flatness and appearance of the top surface of the head of the screw body 114 to be tested, so as to detect whether there is any defect in the appearance of the head of the screw body 114 to be tested. In other words, the type of the sensor body 112 can be changed accordingly according to the detection requirements and is not limited to the method of this embodiment.
