Description

Technical Field

[0001] The utility model relates to the technical field of shaft workpiece processing devices, in particular to an automatic straightening machine for shaft workpieces. Background Art

[0002] A shaft is a cylindrical object that is inserted in the middle of a bearing, a wheel, or a gear, but a few are square. A shaft is a mechanical part that supports rotating parts and rotates with them to transmit motion, torque, or bending moment. It is generally in the shape of a metal round rod, and each section can have different diameters. The parts that make rotating motion in the machine are installed on the shaft. In the prior art, when processing shaft parts, shaft parts may bend. When shaft parts are bent, it is difficult to measure it by human eyes alone, and even if the shaft parts are judged to be bent in time, they cannot be corrected, which is time-consuming and laborious.

[0003] A Chinese patent (publication number CN217798180U) discloses an automatic straightening machine for shaft-like workpieces, including a base, a conveyor line, a bracket, a straightening mechanism and a support rod; when the conveyor line drives the shaft-like parts on the support rod to move to the bottom of the straightening mechanism, the lifting assembly will start to start, and the lifting assembly will drive the pressing member and the rotating drive assembly arranged at the bottom thereof to slowly move toward the conveyor line. At this time, the pressing member will be connected with the support rod arranged on the conveyor line. When the pressing member is connected with the support rod, the pressing member and the support rod will restrict the shaft-like parts. At this time, the rotating drive assembly arranged below the lifting assembly will be connected with the shaft-like parts. At this time, when the rotating drive assembly is started, the rotating drive assembly will drive the shaft-like parts to rotate. When one side of the shaft-like parts is bent, the circular runout of the shaft-like parts will inevitably deviate, so by measuring the circular runout of the shaft-like parts, it is possible to determine whether the shaft-like parts are bent.

DETAILED DESCRIPTION

[0024] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] See also Figures 1 to 6 As shown, the utility model provides an automatic straightening machine for shaft workpieces, comprising a base 1, a top plate 2 is fixedly installed above the base 1, a screw slide 3 is horizontally arranged below the top plate 2, a sliding plate 4 is installed at the working end of the screw slide 3, a straightening device 5 is installed on the sliding plate 4, a supporting assembly 6 is installed on the base 1, the supporting assembly 6 includes a movable supporting seat 62 for supporting the shaft workpiece, a circular runout monitoring mechanism 8 is installed on one side of the movable supporting seat 62, and a rotating assembly 7 for rotating the shaft workpiece is installed on one side of the base 1.

[0026] By placing the shaft workpiece on the support assembly 6 and adjusting the position of the movable support seat 62 according to the length of the shaft workpiece, the circular runout monitoring mechanism 8 is synchronously driven to adjust the position of the movable support seat 62, and the shaft workpiece is driven to rotate through the rotating assembly 7, and monitored by the circular runout monitoring mechanism 8. When the shaft workpiece is bent, the circular runout of the shaft workpiece will deviate. When the circular runout exceeds the set estimated value, the circular runout monitoring mechanism 8 will transmit a signal to the straightening device 5, and the screw slide 3 will drive the straightening device 5 to move to a suitable position to straighten it.

[0027] See also Figures 1 to 4 As shown, the support assembly 6 includes a fixed support seat 61, a first slider 63 and a slide groove 64; the fixed support seat 61 is installed on the base 1; the slide groove 64 is opened on the fixed support seat 61; the first slider 63 is slidably connected in the slide groove 64, the movable support seat 62 is installed on the first slider 63, and locking mechanisms are installed on both sides of the movable support seat 62.

[0028] By placing the shaft workpiece on the fixed support seat 61 and the movable support seat 62, and by moving the movable support seat 62, the movable support seat 62 will move on the slide groove 64 through the first slider 63 below until the movable support seat 62 moves to a suitable position, while driving the circular runout monitoring mechanism 8 to move, and fixing the position of the movable support seat 62 through the locking mechanism to prevent displacement and affect the monitoring accuracy of the circular runout monitoring mechanism 8, so that it can adapt to shaft workpieces of different lengths, and adjust the position of the circular runout monitoring mechanism 8 according to the length of the shaft workpiece to prevent the monitored circular runout data from being inaccurate and affecting the quality of the shaft workpiece.

[0029] See also Figure 2 and Figure 4 As shown, the locking mechanism includes an extension block 65, a cavity 66, a fixed rod 67, a limit plate 68, a first spring 69 and a pull block 610; the extension block 65 is installed on both sides of the movable support seat 62, and the cavity 66 is arranged in the extension block 65; the fixed rod 67 is movably connected in the cavity 66, and one end of the fixed rod 67 is provided with an abutting portion that can abut against the base 1; the limit plate 68 is installed on the fixed rod 67, and the limit plate 68 abuts against the side wall of the cavity 66; the first spring 69 is sleeved on the fixed rod 67, one end of the first spring 69 abuts against the limit plate 68, and the other end of the first spring 69 abuts against the inner wall of the cavity 66; the pull block 610 is installed at the other end of the fixed rod 67.

[0030] When the position of the movable support seat 62 needs to be adjusted, the pull block 610 is pulled, and the pull block 610 drives the fixed rod 67 to move, and the movement of the fixed rod 67 drives the limit plate 68 to move and squeeze the first spring 69, so that the abutment portion of the fixed rod 67 is no longer abutted on the base 1. At this time, the movable support seat 62 can be moved. When the movable support seat 62 moves to a suitable position, the pull block 610 is released, and the elastic deformation is restored by the first spring 69 to drive the abutment portion to abut on the base 1, so that the movable support seat 62 cannot move to prevent displacement.

[0031] See also Figure 4 As shown, the base 1 is provided with a plug hole 611 which can be plugged into and matched with the abutting portion.

[0032] The abutting portion at one end of the fixing rod 67 is inserted into the insertion hole 611 provided on the base 1 , thereby fixing the movable support seat 62 , so that the movable support seat 62 is stably fixed.

[0039] See also Figure 5 and Figure 6 As shown, the clamping mechanism includes a connecting rod 76, a clamping plate 77, a second spring 78 and a pulling plate 79; the connecting rod 76 is movably connected in the rotating cylinder 75; the clamping plate 77 is installed at one end of the connecting rod 76; the second spring 78 is sleeved on the connecting rod 76, one end of the second spring 78 abuts against the clamping plate 77, and the other end of the second spring 78 abuts against the inner wall of the rotating cylinder 75; the pulling plate 79 is installed at the other end of the connecting rod 76.

[0040] By pulling the pull plate 79, the pull plate 79 drives the connecting rod 76 to move, and the connecting rod 76 drives the clamping plate 77 to move and squeeze the second spring 78. At this time, one end of the shaft workpiece is inserted into the rotating cylinder 75.
