Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 4 As shown, an outer diameter detection device for screw production includes a rust removal device and a worktable 2. The rust removal device and the worktable 2 are also equipped with a clamping mechanism for clamping workpiece 101. The worktable 2 is equipped with an outer diameter detection mechanism.

[0022] The outer diameter detection mechanism includes a fixed base 31 fixed on the workbench 2 and a second guide rail 32 located on the workbench 2. A second hydraulic cylinder 33 is installed on one side of the fixed base 31. The piston rod of the second hydraulic cylinder 33 is fixedly connected to a second sliding seat 34. The second sliding seat 34 is slidably engaged with the second guide rail 32. A detection seat 35 is detachably connected to the second sliding seat 34. A first fixed platform 36, a third guide rail 37, and a second fixed platform 38 are installed on the detection seat 35 from top to bottom. The third guide rail 37 is located between the first fixed platform 36 and the second fixed platform 38. A lifting detector 41 is slidably connected to the third guide rail 37. A first detection end 411 is installed below the lifting detector 41. A lifting motor 42 is installed above the first fixed platform 36. The lifting detector 41 is fixed on the lifting rod of the lifting motor 42. A second detection end 43 is installed on the second fixed platform 38.

[0023] A dimension column 44 is also installed between the first fixed platform 36 and the second fixed platform 38. The dimension column 44 passes through the lifting detector 41 and has scale lines 45 on it.

[0024] In this utility model, the lifting detection instrument 41 is existing technology.

[0025] Using the above structure, the clamping mechanism can clamp the rust-removed workpiece 101 on the rust removal device and move the workpiece 101 to the right to the outer diameter detection mechanism. The piston rod of the second hydraulic cylinder 33 of the fixed seat 31 pushes the detection seat 35 to the left, so that the second detection end 43 of the second fixed seat 31 on the detection seat 35 moves to the bottom of one end of the workpiece 101. Then, the clamping mechanism moves the workpiece 101 downward until the bottom of the workpiece 101 abuts against the upper surface of the second detection end 43. Then, the lifting motor 42 starts, and the lifting rod of the lifting motor 42 pushes the lifting detector 41 downward, so that the lifting detector 41 moves downward on the third guide rail 37. The lifting and detection instrument 41 moves and makes the first detection end 411 abut against the top of the workpiece 101. The first detection end 411, the second detection end 43, and the lifting and detection instrument 41 can detect the outer diameter of the workpiece 101 in real time. The scale line 45 on the dimension column 44 set on one side can be read through the distance between the first detection end 411 and the second detection end 43 of the lifting and detection instrument 41. This allows the operator to clearly and in real time detect the scale of the outer diameter of the workpiece 101, which is conducive to automatic detection and convenient for the operator to observe. At the same time, automatic detection can be performed after rust removal, which greatly reduces manual labor and improves detection efficiency.

[0026] Specifically, such as Figures 1 to 4 As shown, the rust removal device includes a drive mechanism 53 that can horizontally move the workpiece 101, a rust removal table 52, and a limiting cylinder 51 for inserting the workpiece 101. A rust removal box 54 is installed on the rust removal table 52, and a drive motor 55 is installed inside the rust removal box 54. A rust removal wheel 56 for rust removal is connected to the output shaft of the drive motor 55.

[0027] A third hydraulic cylinder 531 is installed on the drive mechanism 53. A limiting cylinder 51 is installed on the third hydraulic cylinder 531. A slot 511 for inserting and limiting the workpiece 101 is provided in the limiting cylinder 51.

[0028] With the above structure, the rust removal box 54 has a feed port and a discharge port on both sides in sequence. The drive mechanism 53 includes a fourth guide rail and a drive platform. The drive platform is slidably arranged on the fourth guide rail, which can drive the limiting cylinder 51 to move horizontally to the left or right. At the same time, with the action of the piston rod of the third hydraulic cylinder 531, the workpiece 101 on the limiting cylinder 51 can be moved from one side of the rust removal box 54 to the other side of the rust removal box 54. This is conducive to automatically removing rust from the workpiece 101 and facilitating the conveying of the workpiece 101. It has a good driving and conveying function.

[0029] like Figures 1 to 4As shown, the gripping mechanism includes a gripping frame 61, a first guide rail 62 is mounted below the gripping frame 61, a first sliding seat 63 is slidably connected to the first guide rail 62, two first hydraulic cylinders 66 are symmetrically connected to the first sliding seat 63, a gripper frame 64 is mounted on the piston rod of the first hydraulic cylinders 66, and two mechanical grippers 65 for gripping the workpiece 101 are symmetrically mounted on the gripper frame 64.

[0030] In this utility model, the mechanical gripper 65 is existing technology.

[0031] like Figures 1 to 4 As shown, a collection trough 8 is also provided on the workbench 2.

[0032] With the above structure, the first sliding seat 63 on the first guide rail 62, due to its sliding setting, can drive the mechanical gripper 65 on the gripper frame 64 on the first sliding seat 63 to move left or right. Through the movement of the mechanical gripper 65 on the first sliding seat 63, it can first move to one side of the rust removal box 54, clamp the workpiece 101 located below it, and move it to the right to move the workpiece 101 to the outer diameter detection mechanism. By setting the first hydraulic cylinder 66, the workpiece 101 can be lifted up or lowered to adjust the height of the workpiece 101, which is conducive to accurately placing the workpiece 101 against the first detection end 411, which is conducive to precise adjustment and makes the subsequent detection quality higher. At the same time, the mechanical gripper 65 is automatically controlled to perform the clamping and placement operations. After the outer diameter detection, the mechanical gripper 65 moves the workpiece 101 again to place the workpiece 101 into the collection groove 8 of the worktable 2, which is convenient for conveying the workpiece 101, with better clamping effect and high automation efficiency.

[0033] like Figures 1 to 4 As shown, the highest height of the second detection end 43 is always equal to the height of the lowest end of the workpiece 101 being measured.

[0034] like Figures 1 to 4 As shown, the lifting detector 41 is also equipped with a digital display screen 7 that can display the outer diameter width. By adding the digital display screen 7, it is convenient for observers to record and observe the value of the outer diameter of the workpiece 101 in real time, which facilitates the rapid detection of the outer diameter of the workpiece 101.

[0035] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention 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 indication will also change accordingly.

[0036] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the word "and / or" throughout the text means including three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.
