Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] Please see Figures 1-5 The present invention provides the following technical solution:

[0027] Ball screw production and testing equipment includes:

[0028] The testing unit is integrated 100, including the ball screw 101 to be tested;

[0029] The testing table 110 includes a screw fixing block 120 located on the upper end of the testing mechanism integration 100 for fixing the ball screw 101 to be tested, a thread smoothing testing mechanism 130 located on the outer surface of the ball screw 101 to be tested for finished product testing of the ball screw 101, and a limiting contact structure 140 connected to the thread smoothing testing mechanism 130 for adjusting the pressure of the thread smoothing testing mechanism 130.

[0030] And, a drive mechanism 200 for driving when performing tests on the test bench 110.

[0031] In a specific embodiment of this utility model, the testing table 110 is provided with a lead screw fixing block 120 for securely fixing the ball screw 101 to be tested on the testing table 110. A thread smoothing detection mechanism 130 is provided on the outer surface of the ball screw 101 to check whether the thread of the ball screw 101 is smooth. A limiting contact structure 140 is connected to the thread smoothing detection mechanism 130 to adjust the pressure and ensure that the detection mechanism maintains proper contact with the ball screw 101 to be tested. When the ball screw 101 to be tested is tested, it is driven by the drive mechanism 200. The ball screw 101 to be tested, which is fixed in the screw fixing block 120, rotates. As the ball screw 101 rotates, the thread groove detection slider 132 moves along the thread groove of the ball screw 101. If unevenness or defects are detected in the thread, the transverse slider 131 will be pushed to move upward in the sliding groove 135 and squeeze the limit spring 133 to retract until the convex contact block 134 triggers the contact sensor 136 to issue an alarm signal, thereby realizing automatic defect detection. It can effectively detect the thread quality of the ball screw and improve detection efficiency through automated drive.

[0032] Please refer to the details. Figures 1-5 The lead screw fixing block 120 is provided in two sets. Each set of lead screw fixing blocks 120 includes a lead screw fixing groove 121, a reinforcing thread groove 122 and a detection and reinforcing bolt 123. The lead screw fixing groove 121 is opened at one end of the lead screw fixing block 120, the reinforcing thread groove 122 is opened at the upper end of the lead screw fixing block 120, and the detection and reinforcing bolt 123 is threaded into the reinforcing thread groove 122.

[0033] In this embodiment, two lead screw fixing blocks 120 are provided. A lead screw fixing groove 121 is opened on one end face of the lead screw fixing block 120 to accommodate the shaft end of the ball screw 101 to be tested and achieve preliminary positioning. One lead screw fixing block 120 is screwed into the reinforcing thread groove 122 by a threaded connection. Its lower end can press down on the shaft end of the ball screw to enhance the stability of the fixation. The other lead screw fixing block 120 is not fixed to the ball screw 101 to be tested, so as to realize the free rotation of the ball screw 101 to be tested.

[0034] Please refer to the details. Figures 1-5 The thread smoothing detection mechanism 130 includes a transverse slider 131, a thread groove detection slider 132, a limiting spring 133, a convex contact block 134, a sliding groove 135, and a contact sensor 136. The thread groove detection slider 132 is slidably connected to the thread groove of the ball screw 101 to be tested. The transverse slider 131 is fixedly connected to the upper end of the thread groove detection slider 132. The sliding groove 135 is opened at the lower end of the thread smoothing detection mechanism 130 and is slidably connected to the sliding groove 135. The limiting spring 133 is fixedly connected to the upper end of the transverse slider 131 and the upper inner wall of the sliding groove 135. The convex contact block 134 is fixedly connected to the upper end of the transverse slider 131. The contact sensor 136 is located on the upper inner wall of the sliding groove 135.

[0035] In this embodiment: the thread smoothing detection mechanism 130 is used to perform continuous contact detection on the thread surface of the ball screw 101 to be tested, ensuring the smoothness and consistency of its thread groove. The thread groove detection slider 132 is shaped to match the ball screw thread and can slide along the thread groove of the ball screw 101 to scan the entire thread surface. The limiting spring 133 is disposed between the upper end of the transverse slider 131 and the upper inner wall of the sliding groove 135, providing a downward reset force so that the thread groove detection slider 132 is always in close contact with the bottom of the ball screw thread groove. The distance between the contact sensor 136 and the convex contact block 134 is... The small size is used to receive the trigger signal of the convex contact block 134 and feed back the abnormal information to the control system. When the drive mechanism 204 drives the thread smoothing detection mechanism 130 to move axially along the ball screw 101 to be tested, the thread groove detection slider 132 slides synchronously in the thread groove of the ball screw. If there are defects such as burrs, depressions or protrusions on the thread surface, the thread groove detection slider 132 will be obstructed and push the transverse slider 131 upward, thereby causing the convex contact block 134 to compress the limit spring 133 and touch the contact sensor 136. At this time, the system will immediately issue an alarm signal to prompt the operator to check and handle the problem.

[0036] Please refer to the details. Figures 1-5 The limiting contact structure 140 includes an upward sliding groove 141, an upward sliding plate 142, and a return spring 143. The upward sliding groove 141 is formed on the upper inner wall of the sliding groove 135. The upward sliding plate 142 is slidably connected in the upward sliding groove 141. The upward sliding plate 142 is fixedly connected to the upper end of the upward sliding plate 142 and the upper inner wall of the upward sliding groove 141.

[0037] In this embodiment, the limiting contact structure 140 is disposed inside the thread smoothing detection mechanism 130 to adjust and control the contact pressure between the thread groove detection slider 132 and the ball screw thread, so as to avoid damage to the contact sensor 136. When the thread groove detection slider 132 moves upward due to encountering a thread surface defect, it drives the horizontal slider 131 and the upward sliding plate 142 fixed thereto to rise together. At this time, the return spring 143 is compressed, and at the same time, it triggers the signal transmission between the convex contact block 134 and the contact sensor 136. After the detection is completed, under the action of the return spring 143, the upward sliding plate 142 automatically resets along the upward sliding groove 141, so that the entire detection mechanism returns to the initial state and is ready to perform the next detection, thus avoiding damage to the contact sensor 136 due to excessive pressure.

[0038] Please refer to the details. Figures 1-5 The drive mechanism 200 includes a drive motor 201, a limiting slide rail 202 and a limiting slider 203. The limiting slide rail 202 is fixedly connected to the upper end of the detection table 110, the limiting slider 203 is slidably connected to the outer surface of the limiting slide rail 202, and the drive motor 201 is fixedly connected to one side of the detection table 110.

[0039] In this embodiment: the limiting slide rail 202 is fixedly installed on the upper surface of the detection table 110 and is arranged in a straight line to guide the movement trajectory of the detection component and ensure that it runs smoothly in the set direction. The limiting slider 203 is slidably connected to the outer surface of the limiting slide rail 202 and can make linear reciprocating motion along the slide rail. The limiting slider 203 is fixedly connected to the thread smoothing detection mechanism 130, thereby driving it to move synchronously.

[0040] Please refer to the details. Figures 1-5 One lead screw fixing block 120 is fixedly connected to the upper end of the detection table 110, and the other lead screw fixing block 120 is fixedly connected to the output end of the drive motor 201.

[0041] In this embodiment: the lead screw fixing block 120, which is fixed to the output end of the drive motor 201, is screwed into the reinforcing thread groove 122 by a threaded connection. Its lower end can press down on the shaft end of the ball screw, thereby driving the ball screw 101 to be tested to rotate through the drive motor 201. The lead screw fixing block 120, which is fixed at the upper end of the test table 110, does not need to be fixed by the test reinforcing bolt 123, thus enabling it to rotate freely.

[0042] The working principle and usage process of this utility model are as follows: The testing table 110 is equipped with a lead screw fixing block 120 for securely fixing the ball screw 101 to be tested onto the testing table 110. A thread smoothing detection mechanism 130 is provided on the outer surface of the ball screw 101 to check the smoothness of its threads. A limiting contact structure 140 is connected to the thread smoothing detection mechanism 130 to adjust the pressure and ensure proper contact between the detection mechanism and the ball screw 101. When testing the ball screw 101, the drive mechanism 200... The ball screw 101 to be tested, which is fixed in the screw fixing block 120, is driven to rotate. As the ball screw 101 to be tested rotates, the thread groove detection slider 132 moves along the thread groove of the ball screw 101 to be tested. If unevenness or defects are detected in the thread, the transverse slider 131 will be pushed to move upward in the sliding groove 135 and squeeze the limit spring 133 to retract until the convex contact block 134 triggers the contact sensor 136 to issue an alarm signal, thereby realizing automatic defect detection. It can effectively detect the thread quality of the ball screw and improve the detection efficiency through automated drive.

[0043] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
