[0026] Reference below Figures 1 to 3 To describe the straight axis straightening machine according to an embodiment of the utility model.
[0027] According to the straight axis straightening machine of the embodiment of the utility model, it includes a mobile platform, a limit rod 300 and a correction assembly 400, the mobile platform includes a first mobile platform 110, a second mobile platform 120, a third mobile platform 130 and a fourth mobile platform 140 that can move on a plane, and the first mobile platform 110, the second mobile platform 120, the third mobile platform 130 and the fourth mobile platform 140 are respectively provided with a support part 200; the first mobile platform 110 and the second mobile platform 120 move to form a space between the two support parts 200 thereon The first support point, the third mobile platform 130 and the fourth mobile platform 140 are moved to form a second support point between the two support parts 200 thereon; the mobile platform supports the straight shaft 600 to be corrected through the first support point and the second support point; the limit rod 300 is located above the first support point and the second support point; the top of the correction component 400 is slidably arranged on the limit rod 300, so that the correction component 400 can move above the straight shaft 600 to be corrected; the bottom of the correction component 400 is used to move downward to press down and correct the part to be corrected of the straight shaft 600 to be corrected.
[0028] For example Figure 1 and Figure 3 As shown, the first mobile platform 110, the second mobile platform 120, the third mobile platform 130 and the fourth mobile platform 140 can move on a plane, that is, move in the X and Y directions, so as to adjust the distance between each mobile platform to accommodate the straight shaft 600 to be corrected with different diameters and different lengths.
[0029] For example Figure 3 As shown, the two ends of the straight shaft 600 to be corrected are placed on the first support point and the second support point, and a straight line is determined by the two points, so that the straight shaft 600 to be corrected is stably set on the mobile platform, which is convenient for correcting the straight shaft 600 to be corrected. The limit rod 300 is located above the first support point and the second support point, and the straight shaft 600 to be corrected is located on the first support point and the second support point, so that the limit rod 300 can be located above the straight shaft 600 to be corrected. The correction component 400 slides on the limit rod 300, so that the part to be corrected of the straight shaft 600 to be corrected can be corrected above the straight shaft 600 to be corrected. By rotating the straight shaft 600 to be corrected on the first support point and the second support point, the straight shaft 600 to be corrected can be corrected around. After the correction of this part of the straight shaft 600 to be corrected is completed, the correction assembly 400 can be moved above the straight shaft 600 to be corrected along the axial direction of the limiting rod 300, so as to perform an all-round detection on the straight shaft 600 to be corrected.
[0030] Through such an arrangement, the straight shaft straightening machine can have a simple structure, low cost, easy operation, high practicality, reduce the maintenance cost of shaft correction, without reducing the basic requirements of the shaft, and can be carried out directly at each production site.
[0031] In some specific embodiments of the present invention, the first mobile platform 110, the second mobile platform 120, the third mobile platform 130 and the fourth mobile platform 140 are arranged in a T-shaped field on a plane, and the first mobile platform 110, the second mobile platform 120, the third mobile platform 130 and the fourth mobile platform 140 move along the X and Y directions on the plane.
[0032] For example Figure 1 and Figure 3 As shown, the first mobile platform 110, the second mobile platform 120, the third mobile platform 130 and the fourth mobile platform 140 are arranged in a T-shaped field on the plane, and the first mobile platform 110, the second mobile platform 120, the third mobile platform 130 and the fourth mobile platform 140 can all move along the X and Y directions on the plane.
[0033] Through the movement of the mobile platform, when the diameter of the straight shaft 600 to be corrected is large, the distance between the first mobile platform 110 and the second mobile platform 120, and the distance between the third mobile platform 130 and the fourth mobile platform 140 are correspondingly increased. When the diameter of the straight shaft 600 to be corrected is small, the distance between the first mobile platform 110 and the second mobile platform 120, and the distance between the third mobile platform 130 and the fourth mobile platform 140 are correspondingly decreased. When the straight shaft 600 to be corrected is long, the distance between the first mobile platform 110 and the third mobile platform 130, and the distance between the second mobile platform 120 and the second mobile platform 120 are increased. When the straight shaft 600 to be corrected is short, the distance between the first mobile platform 110 and the third mobile platform 130, and the distance between the second mobile platform 120 and the second mobile platform 120 are decreased.
[0034] By setting up a mobile platform, the straight axis straightening machine can correct straight axes of different sizes.
[0035] In some specific embodiments of the present invention, the first mobile platform 110 and the second mobile platform 120 are consistent in the X direction, and the third mobile platform 130 and the fourth mobile platform 140 are consistent in the X direction; the first mobile platform 110 and the third mobile platform 130 are consistent in the Y direction, and the second mobile platform 120 and the fourth mobile platform 140 are consistent in the Y direction.
[0036] For example Figure 1 and Figure 2As shown, the first mobile platform 110 and the second mobile platform 120 are consistent in the X direction, and the third mobile platform 130 and the fourth mobile platform 140 are consistent in the X direction, so that a first support point can be formed between the two support parts 200 on the first mobile platform 110 and the second mobile platform 120, and a second support point can be formed between the two support parts 200 on the third mobile platform 130 and the fourth mobile platform 140. The straight axis 600 to be corrected is supported by the first support point and the second support point. The first mobile platform 110 and the third mobile platform 130 are consistent in the Y direction, and the second mobile platform 120 and the fourth mobile platform 140 are consistent in the Y direction, ensuring that the straight axis 600 to be corrected can be accurately placed under the limit rod 300 and corrected by the correction component 400.
[0037] In some specific embodiments of the present invention, the support portion 200 includes a support rod 210 and a support member 220, the support rod 210 is fixedly arranged on the first mobile platform 110, the second mobile platform 120, the third mobile platform 130 and the fourth mobile platform 140, and the support member 220 is fixedly connected to the support rod 210.
[0038] For example Figure 1 and Figure 2 As shown, the support part 200 includes a support rod 210 and a support member 220. The support rod 210 is fixedly arranged on the first mobile platform 110, the second mobile platform 120, the third mobile platform 130 and the fourth mobile platform 140, and is fixedly connected to the first mobile platform 110, the second mobile platform 120, the third mobile platform 130 and the fourth mobile platform 140. The support member 220 is fixedly connected to the support rod 210. One end of the support rod 210 is fixedly arranged on the mobile platform, and the other end is fixedly connected to the support member 220, so that the position of the support member 220 is raised, which is convenient for placing the straight shaft 600 to be corrected.
[0039] Furthermore, the support rod 210 can be fixedly connected to the mobile platform and the support member 220 by welding, threaded screw connection, or other methods.
[0040] In some specific embodiments of the present invention, the support member 220 is a circular wheel structure, a first support point is formed between the arc surfaces of the two support members 220 of the first mobile platform 110 and the second mobile platform 120, and a second support point is formed between the arc surfaces of the two support members 220 of the third mobile platform 130 and the fourth mobile platform 140.
[0041] For example Figure 1 and Figure 2As shown, the support member 220 is a circular wheel structure, and a first support point is formed between the arc surfaces of the two support members 220 of the first mobile platform 110 and the second mobile platform 120, and a second support point is formed between the arc surfaces of the two support members 220 of the third mobile platform 130 and the fourth mobile platform 140.
[0042] By providing the circular wheel structure and the arc surface, the placement of the straight shaft 600 to be corrected is made more stable.
[0043] In some specific embodiments of the present invention, the support rod 210 is fixedly connected to the circular wheel axis of the support member 220 .
[0044] For example Figure 2 and Figure 3 As shown, the support rod 210 is connected to the circular wheel axis of the support member 220, so that the connection between the support rod 210 and the support member 220 is more stable, so that the support member 220 can more stably support the straight shaft 600 to be corrected.
[0045] In some specific embodiments of the present invention, the correction component 400 includes a sleeve portion 410, which is disposed on the top of the correction component 400, and the sleeve portion 410 is movably sleeved on the limit rod 300, and the correction component 400 moves on the limit rod 300 through the sleeve portion 410.
[0046] For example Figure 1 and Figure 2 As shown, the correction component 400 includes a sleeve portion 410, which is arranged at the top of the correction component 400 and fixedly connected to the top shaft rod 420. The sleeve portion 410 is movably sleeved on the limit rod 300 and can move along the axial direction of the limit rod 300, so that the correction component 400 moves on the limit rod 300 along the axial direction of the limit rod 300 through the sleeve portion 410, thereby driving the top shaft rod 420 to move above the straight shaft 600 to be corrected, so that there is no need to move the straight shaft 600 to be corrected. By moving the correction component 400, the straight shaft 600 to be corrected can be corrected, and the operation is more convenient.
[0047] In some specific embodiments of the present invention, the correction component 400 includes a top shaft rod 420, and the top shaft rod 420 is a screw rod structure. The top shaft rod 420 is rotated to move the top shaft rod 420 up and down to correct the straight shaft 600 to be corrected.
[0048] For example Figure 2As shown, the correction component 400 also includes a top shaft rod 420, wherein the top shaft rod 420 is a screw structure, and the top shaft rod 420 is rotated so that the lower end surface of the top shaft rod 420 abuts against the part to be corrected of the straight shaft 600 to be corrected, and then the top shaft rod 420 is rotated so that the top shaft rod 420 is pressed downward, thereby pressing the convex surface of the straight shaft 600 to be corrected downward, and correcting the straight shaft 600 to be corrected.
[0049] The top shaft rod 420 is a screw structure, which can convert rotational motion into linear motion, so that the straight shaft 600 to be corrected can be corrected by rotating the top shaft rod 420.
[0050] In some specific embodiments of the present invention, a dial indicator (500) is further included. The dial indicator (500) is arranged below the straight shaft (600) to be corrected and is located directly below the top shaft rod (420) to follow the top shaft rod (420) and move along the axial direction of the limit rod (300). The dial indicator (500) is used to detect the curvature of the straight shaft (600) to be corrected.
[0051] For example Figure 2 As shown, a dial gauge 500 is also included. The dial gauge 500 is arranged below the straight shaft (600) to be corrected and is located directly below the top shaft rod (420). It follows the top shaft rod (420) and moves along the axial direction of the limit rod (300). According to the method for measuring the curvature of the shaft, the straight shaft 600 to be corrected is radially rotated to measure the curvature of the straight shaft 600 to be corrected. The curvature point of the straight shaft 600 to be corrected is found by the dial gauge 500, and the convex surface of the straight shaft 600 to be corrected is turned upward. Then, the top shaft rod 420 is moved to the top of the convex surface, and the convex surface of the straight shaft 600 to be corrected is rotated and slowly pressed down to straighten the straight shaft 600 to be corrected.
[0052] If the dial gauge 500 does not detect that there is a convex point at this part of the straight shaft 600 to be corrected, the dial gauge 500 follows the top shaft rod 420 and moves a certain distance along the axial direction of the limit rod 300, that is, the axial direction of the straight shaft 600 to be corrected, to the part that has not been detected by the dial gauge 500 for detection. At this time, the straight shaft 600 to be corrected still rotates one circle, so that the dial gauge 500 can detect it.
[0053] In some specific embodiments of the utility model, a rotating mechanism is further included, wherein the rotating mechanism is connected to the straight shaft (600) to be corrected and is used to rotate the straight shaft (600) to be corrected. When the dial indicator (500) detects that there is a convex point on the straight shaft (600) to be corrected, the rotating mechanism automatically rotates the straight shaft (600) to be corrected by 180° so that the convex point faces the bottom surface of the top shaft rod (420).
[0054] For example Figure 3As shown, the rotating mechanism is connected to the straight shaft 600 to be corrected, and is used to automatically rotate the straight shaft 600 to be corrected. When the dial indicator (500) detects that there is a convex point on the straight shaft (600) to be corrected, the straight shaft (600) to be corrected is automatically rotated 180 degrees so that the convex point faces the bottom surface of the top shaft rod (420), and at this time, the top shaft rod rotates slowly to press down the convex surface of the straight shaft 600 to be corrected, so as to straighten the straight shaft 600 to be corrected.
[0055] Furthermore, a control system is also included, which is connected to the rotating mechanism, the correction component, and the dial indicator 500. The rotating mechanism rotates the straight shaft 600 to be corrected to detect its curvature. When the dial indicator 500 detects that the straight shaft 600 to be corrected has a convex point, the control system controls the top shaft rod 420 to rotate one circle or half a circle, so that the top shaft rod 420 presses and corrects the straight shaft 600 to be corrected. At this time, the rotating mechanism rotates the straight shaft 600 to be corrected again for one circle to detect its surface curvature. If a convex point is still detected, it is still corrected. If no convex point is detected, the control system controls the sleeve 410 to move to the next monitoring point along the limit rod 300, and the top shaft rod 420 and the dial indicator 500 move synchronously, so that the dial indicator 500 remains at a position directly below the top shaft rod 420. At this time, the straight shaft 600 to be corrected is detected again, and the above steps are repeated until the entire straight shaft 600 to be corrected is detected.
[0056] Furthermore, the dial indicator 500 sends the recorded curvature data of the surface of the straight shaft 600 to be corrected to the control system. The control system can record and analyze the data of the straight shaft 600 to be corrected, analyze the tolerance of the straight shaft 600 to be corrected, and judge the factory flatness of the straight shaft 600 to be corrected according to the value of the tolerance, that is, the flatness before correction, so as to facilitate finding high-quality suppliers or focusing on improving the flatness of their own straight shafts.
[0057] Furthermore, for example Figure 2 As shown, a support frame 310 is also included. The support frame 310 is fixedly arranged, and the limiting rod 300 is arranged on the support frame 310 to maintain the stability of the limiting rod 300, thereby ensuring the stability of the movement of the top shaft rod 420.
