[0005] A further improvement is that the lower end of the detection rod is provided with a replaceable tip.

[0006] A further improvement is that it also includes an insulating plate, the height detection sensor is installed at one end of the insulating plate, the other end of the insulating plate is fixedly connected to the lifting plate, and the insulating plate is provided with a through hole for the position detection strip to pass through.

[0007] A further improvement is that: mounting seats are provided at both ends of the fixing plate, and the lower end of the lifting guide rod is inserted into the corresponding mounting seat.

[0008] A further improvement is that the fixing plate is provided with a lower connecting seat, the positioning plate is provided with an upper connecting seat, and the two ends of the position detection strip are respectively connected to the lower connecting seat and the upper connecting seat.

[0009] This utility model also provides a gripping mechanism, including a gripper body, a chuck at the lower end of the gripper body, a plurality of locking blocks at the bottom of the chuck, and a positioning detection device as described above on the gripper body.

If inaccurate, the machine is stopped immediately, reducing the risk of damage to the gripper due to excessive descent and collision with the workpiece. The height detection sensor is connected to the detection rod via an insulating plate to reduce the impact of electrical charge when the gripper is heated with the workpiece. By comparing the workpiece and gripper displacement distance, the descent distance of the gripper is controlled to prevent excessive descent and collision with the workpiece (or other machine tool components), thus avoiding damage. This invention has good practical application value and promotes economic benefits in production. Attached Figure Description

[0028] See Figures 1-4 As shown, this utility model embodiment provides a positioning and detection device for ball cage-type parts, including a fixing plate 101, a positioning plate 110, a position detection bar 112, a lifting plate 106, a height detection sensor 109, and a detection rod 104;

[0029] The positioning plate 110 is located directly above the fixing plate 101, and both ends of the positioning plate 110 are connected to the fixing plate 101 via lifting guide rods 107. Specifically, the fixing plate 101 has mounting seats 102 at both ends, and the lower end of the lifting guide rods 107 is inserted into the corresponding mounting seats 102.

[0030] The two ends of the position detection strip 112 are connected to the positioning plate 110 and the fixing plate 101, respectively. Specifically, the fixing plate 101 is provided with a lower connecting seat 103, the positioning plate 110 is provided with an upper connecting seat 111, and the two ends of the position detection strip 112 are connected to the lower connecting seat 103 and the upper connecting seat 111, respectively.

[0031] The two ends of the lifting plate 106 are slidably connected to the two lifting guide rods 107 respectively;

[0032] A height detection sensor 109 is installed on the lifting plate 106 to detect the height of the position detection strip 112. Specifically, it also includes an insulating plate 108. The height detection sensor 109 is installed at one end of the insulating plate 108, and the other end of the insulating plate 108 is fixedly connected to the lifting plate 106. The insulating plate 108 is provided with a through hole for the position detection strip 112 to pass through.

[0033] The upper end of the detection rod 104 passes through the fixing plate 101 and connects to the lifting plate 106. Specifically, the lower end of the detection rod 104 is provided with a replaceable center head 105, which can be replaced at any time for different workpieces.

[0034] See Figures 5-6 As shown, this embodiment of the utility model also provides a gripping mechanism, including a gripper body 2, a chuck 3 at the lower end of the gripper body 2, a plurality of clamping blocks 31 at the bottom of the chuck 3, and a positioning detection device 1 as described above on the gripper body 2. Specifically, a fixing plate 101 is fixedly connected to the gripper body 2, and a detection rod 104 passes downward through the gripper body 2 and the chuck 3 in sequence, with the lower end of the detection rod 104 extending beyond the plane where the clamping blocks 31 are located.

A motor 6 for driving the clamping blocks 31 to grip the workpiece is provided on the connecting plate 5.

[0035] When the workpiece gripper descends to pick up the workpiece, the positioning detection device detects whether the workpiece is positioned accurately. The detection rod descends with the gripper and contacts the workpiece before the gripper. After contacting the workpiece, the detection rod remains stationary while the gripper continues to descend. The height detection sensor mounted on the detection rod detects the descent distance of the gripper in real time. Since the descent distance of the gripper is the longest when the workpiece is accurately positioned and placed stably, the accuracy of the workpiece positioning can be determined by comparing the set descent height of the gripper with the actual descent height reached by the height detection sensor.
