Description

Technical Field

[0001] The utility model relates to the technical field of screw rod processing, in particular to an automatic straightening device for rod-shaped parts. Background Art

[0002] Rod-shaped parts are widely used, and the screw rod is one of the rod-shaped parts. It is the most commonly used transmission component in machine tools and precision machinery. Its main function is to convert rotational motion into linear motion, or convert torque into axial reciprocating force, and at the same time has the characteristics of high precision, reversibility and high efficiency. Due to its very small frictional resistance, the screw rod is widely used in various industrial equipment and precision instruments.

[0003] During the processing of the screw rod, the situation of axial non-straightness may occur and needs to be straightened. At present, most of the screw rod straightening adopts manual straightening, which has low efficiency, high working intensity and high requirements for the experience of operators, and is very inconvenient.

[0004] In view of this, there is an urgent need for an automatic straightening device for rod-shaped parts. Summary of the Utility Model

[0005] Aiming at the problems existing in the prior art, the utility model uses the following technical structure to solve this problem.

[0006] To achieve the above object, the utility model adopts the following technical scheme:

[0007] An automatic straightening device for rod-shaped parts, comprising: a machine table, on which a stamping component, a screw rod fixing component, a first driving component, a second driving component and a detection component are arranged. The screw rod fixing component is used to fix the screw rod. The first driving component is used to rotate the screw rod at the screw rod fixing component. The second driving component is used to move the screw rod at the screw rod fixing component along the axial direction of the screw rod;

[0008] The detection component includes a detection piece and a measuring tool. The detection piece is arranged directly below the screw rod at the screw rod fixing component. The top end of the detection piece is in contact with the screw rod. The measuring tool is used to measure the horizontal height of the detection piece in real time;

[0009] The stamping component includes a stamping head, and the stamping head is arranged directly above the detection piece.

[0010] It is further characterized in that

[0011] The measuring tool is a dial indicator or a micrometer.

[0012] The detection component further includes a support and an L-shaped transmission plate. The support is arranged on the machine table. The corner of the transmission plate is rotatably arranged on the support. The detection piece is arranged on the top surface of the horizontal part of the transmission plate. The measuring tool is arranged on the support. The detection end of the support abuts against the side of the vertical part of the transmission plate away from the detection piece.

[0013] A U-shaped clamping seat is arranged on the transmission plate, and the detection piece is arranged on the U-shaped clamping seat.

[0014] The extending direction of the detection piece is consistent with the axial direction of the lead screw.

[0015] The lead screw fixing component includes two carrier plates and two end fixing seats. The two carrier plates are slidably arranged on the top surface of the machine table. The two end fixing seats are respectively arranged on the two carrier plates. The lead screw fixing ports are rotatably arranged on the sides of the two end fixing seats close to each other.

[0016] Two parallel slide rails are arranged on the top surface of the machine table, and the two carrier plates are slidably clamped on the two slide rails.

[0017] The second driving component includes a first motor, a driving lead screw and a connecting plate. The driving lead screw is horizontally arranged above the machine table. The output end of the first motor is coaxially connected to the driving lead screw. The connecting plate is threadedly connected to the driving lead screw. The two carrier plates are both connected to the connecting plate.

[0018] Two linear mounting holes are arranged on the connecting plate. The extending direction of the mounting holes is the same as the axial direction of the driving lead screw. The two carrier plates are respectively installed at the two mounting holes through locking components.

[0019] The first driving component is a second motor. The second motor is arranged on one end fixing seat. The output end of the second motor is coaxially connected to the corresponding lead screw fixing port.

[0020] Adopting the above structure of the present utility model can achieve the following beneficial effects:

[0021] The lead screw to be straightened is fixed by the lead screw fixing group. Then the first driving component rotates the lead screw at the lead screw fixing component. When the part in contact with the detection piece meets the requirements, the second driving component makes the lead screw at the lead screw fixing component move a certain distance along the axial direction of the lead screw. Then the first driving component drives the lead screw to rotate, so that the lead screw body passes directly above the detection piece in turn. When the bent part of the lead screw passes through the detection piece, it forces the height position of the detection piece to change. At this time, the measuring tool measures the value of the height change of the detection piece. If the value exceeds the standard value, the punching head of the punching component moves down to straighten the bent part of the lead screw, thus efficiently completing the straightening of the whole lead screw.

Detailed implementation manners

[0026] In order to enable those skilled in the art of this technology to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0027] It should be noted that the terms "including" and "having" in the description and claims of the present utility model and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, device, product or equipment that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or equipment.

[0028] The following is a further detailed description of the present application in conjunction with the attached Figures 1 - 3 Drawings.

[0029] Refer to Figures 1 - 2An automatic straightening device for a rod-shaped part shown in the figure includes: a machine table, on which a stamping assembly 1, a lead screw fixing assembly 2, a first driving assembly 3, a second driving assembly 4 and a detection assembly are arranged. The detection assembly includes a detection piece 5 and a measuring tool 6. The detection piece 5 is arranged directly below the lead screw at the lead screw fixing assembly 2, and the top end of the detection piece 5 contacts the lead screw. The measuring tool 6 is used to measure the horizontal height of the detection piece 5 in real time. The stamping assembly 1 includes a stamping head, which is arranged directly above the detection piece 5. In this way, the lead screw to be straightened is fixed by the lead screw fixing assembly 2, and then the first driving assembly 3 rotates the lead screw at the lead screw fixing assembly 2. When the part in contact with the detection piece 5 meets the requirements, the second driving assembly 4 makes the lead screw at the lead screw fixing assembly 2 move a certain distance along the axial direction of the lead screw, and then the first driving assembly 3 drives the lead screw to rotate, so that the lead screw body passes directly above the detection piece 5 in turn. When the bent part of the lead screw passes through the detection piece 5, it forces the height position of the detection piece 5 to change. At this time, the measuring tool 6 measures the value of the height change of the detection piece 5. If the value exceeds the standard value, the stamping head of the stamping assembly 1 moves down (at this time, the first driving assembly 3 flips the bent part to the upper side, and then the first driving assembly 3 and the second driving assembly 4 stop working), and presses the bent part of the lead screw straight. Of course, support seats A for supporting the lead screw are arranged on both sides of the detection piece 5 on the top surface of the machine table, which cooperate with the stamping head to better stamp the lead screw and efficiently complete the straightening of the lead screw, saving time and effort. Among them, the measuring tool 6 can be reasonably selected according to the straightening standard, and a dial indicator or a micrometer can be selected, etc.

[0030] Reference Figure 2 and Figure 3 As shown, the detection assembly further includes a support 7 and an L-shaped transmission plate 8. The support 7 is arranged on the machine table, and the corner of the transmission plate 8 is rotatably arranged on the support 7. The detection piece 5 is arranged on the top surface of the horizontal part of the transmission plate 8, and the measuring tool 6 is arranged on the support 7. The detection end of the support 7 abuts against the side of the vertical part of the transmission plate 8 away from the detection piece 5. In this way, when the height of the detection piece 5 changes, the transmission plate 8 rotates, so that the measured value of the measuring tool 6 changes to judge whether the straightness of the lead screw meets the requirements. Among them, a U-shaped clamping seat 9 is arranged on the transmission plate 8, and the detection piece 5 is arranged on the U-shaped clamping seat 9, so as to facilitate the replacement of the detection piece 5 and adapt to the straightening of lead screws of different sizes. At the same time, in order to improve the detection accuracy, the extending direction of the detection piece 5 is consistent with the axial direction of the lead screw, and the length of the detection piece 5 is adjusted adaptively according to the detection requirements.

[0031] Reference Figure 3As shown, the lead screw fixing assembly 2 includes two carrier plates 21 and two end fixing seats 22. The two carrier plates 21 are slidably arranged on the top surface of the machine table. The two end fixing seats 22 are respectively arranged on the two carrier plates 21. On one side of the two end fixing seats 22 close to each other, lead screw fixing ports are rotatably arranged. In this way, the two ends of the lead screw are fixed by the two lead screw fixing ports. The lead screw fixing port is provided with a bayonet to clamp the end of the lead screw to keep the lead screw horizontal. At the same time, in order to facilitate the fixing of lead screws of different lengths, two parallel slide rails are arranged on the top surface of the machine table. The two carrier plates 21 are slidably clamped on the two slide rails to adjust the distance between the two lead screw fixing ports to fix lead screws of different lengths. In order to make the lead screw between the two lead screw fixing ports rotate for straightening, the first driving assembly 3 is a second motor. The second motor is arranged on one end fixing seat 22, and the output end of the second motor is coaxially connected to the corresponding lead screw fixing port. The second motor drives the corresponding lead screw fixing port to rotate to make the lead screw rotate.

[0032] Reference Figure 3 As shown, the second driving assembly 4 includes a first motor 41, a driving lead screw 42 and a connecting plate 43. The driving lead screw 42 is horizontally arranged above the machine table. The output end of the first motor 41 is coaxially connected to the driving lead screw 42. The connecting plate 43 is threadedly connected to the driving lead screw 42. The two carrier plates 21 are both connected to the connecting plate 43. In order to make the lead screw at the lead screw fixing assembly 2 move axially, the first motor 41 makes the driving lead screw 42 rotate to make the connecting plate 43 move along the axial direction of the straightened lead screw. At the same time, in order to adjust the distance between the two carrier plates 21, two linear mounting holes 431 are arranged on the connecting plate 43. The extending direction of the mounting holes 431 is the same as the axial direction of the driving lead screw 42. The two carrier plates 21 are respectively installed at the two mounting holes 431 through locking assemblies. In this way, the carrier plates 21 are connected at different positions of the mounting holes 431 to adjust the distance between the two carrier plates 21.

[0033] The working principle of the present utility model: The lead screw to be straightened is fixed by the lead screw fixing assembly 2, and then the first driving assembly 3 makes the lead screw at the lead screw fixing assembly 2 rotate. When the part in contact with the detection piece 5 meets the requirements, the second driving assembly 4 makes the lead screw at the lead screw fixing assembly 2 move a certain distance along the axial direction of the lead screw, and then the first driving assembly 3 drives the lead screw to rotate so that the lead screw body passes directly above the detection piece 5 in turn. When the bent part of the lead screw passes through the detection piece 5, it forces the height position of the detection piece 5 to change. At this time, the measuring tool 6 measures the value of the height change of the detection piece 5. If the value exceeds the standard value, the punching head of the punching assembly 1 moves downward to straighten the bent part of the lead screw, so as to efficiently complete the straightening of the entire lead screw.

[0034] The above are only the preferred embodiments of this application, and the present utility model is not limited to the above embodiments. It can be understood that other improvements and changes directly derived or associated by those skilled in the art without departing from the spirit and concept of the present utility model shall be considered to be included within the protection scope of the present utility model.
