[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] A zinc alloy die casting thread detection device, such as Figure 1-Figure 3As shown, it includes a workbench 1, a bracket 2, a guide plate 3, a guide mechanism 4, a torque sensor 5, a motor 6 and a detection head 7. The bracket 2 is arranged on the workbench 1, and the guide plate 3 is arranged on the bracket 2 through the guide mechanism 4, and the guide mechanism 4 is used to guide the guide plate 3 to move up and down; the motor 6 is arranged in the workbench 1, and the detection head 7 is connected to the motor 6 through the torque sensor 5. The motor 6 is used to drive the detection head 77 to rotate, and the torque sensor 5 is used to collect the torque value of the detection head 7 when it rotates; specifically, the motor 6 is fixed in the workbench 1, the torque sensor 5 is fixed to the bracket 2 through a clamping block, and the input and output ends of the torque sensor 5 are respectively connected to the motor 6 and the detection head 7 through a coupling; the detection head 7 is a thread gauge that cooperates with the internal thread of the tooling.

[0021] The guide mechanism 4 comprises a guide rod 41, a guide sleeve 42, and a spring 43. The guide rod 41 is fixed to the bracket 2, and the guide sleeve 42 is mounted on the guide plate 3. The guide sleeve 42 is slidably connected to the guide rod 41. The spring 43 is mounted on the guide rod 41, with its ends acting on the workbench 1 and the guide plate 3, respectively. The spring 43 provides an upward thrust for the guide plate 3. During testing, the workpiece 9 is placed on the guide plate 3, and the guide plate 3 is pressed to move the workpiece 9 toward the test head 7.

[0022] In one embodiment, if Figure 1-Figure 3 As shown, the guide mechanism 4 also includes a cylinder 44, which is fixed on the bracket 2 and connected to the guide plate 3. Preferably, the cylinder 44 and the guide rod 41 are respectively arranged on both sides of the motor 6. The cylinder 44 is provided to assist the guide plate 3 in force balance, ensuring that it is not disturbed by vibration or other external factors during detection. Specifically, when the thread of the detection head 7 enters the screw hole of the workpiece, it will drive the workpiece up and down to ensure that it can move synchronously with the spring 43 of the guide mechanism 4; by providing the cylinder 44, it actively cooperates with the lifting and lowering of the guide plate 3 to ensure that the reciprocating motion is more stable and reliable, and will not give a large reaction force, thereby protecting the electroplating layer on the surface of the product from damage.

[0023] In one embodiment, if Figure 1-Figure 3 As shown, the motor 6 is connected to a motor switch 61 and a speed regulator 62. The motor switch 61 is used to control the opening of the motor 6, and the speed regulator 62 is used to adjust the speed of the motor 6 to meet different experimental requirements.

[0024] In one embodiment, if Figure 1-Figure 3 As shown, a workpiece seat 31 that matches the shape of the workpiece 9 is provided on the guide plate 3 .

[0025] In the above embodiment, if Figure 1-Figure 3 As shown, the workpiece seat 31 is quickly locked by screws. Therefore, the workpiece seat 31 that matches the tooling can be selected for quick installation, and the equipment can be quickly put into use, thereby increasing the scope of use of the equipment.

[0026] In one embodiment, if Figure 1-Figure 3 As shown, a position sensor 8 is provided on the bracket 2, and the position sensor 8 is used to sense the guide plate 3. Preferably, the position sensor 8 is a proximity switch or a press switch.

[0027] When the present invention is in use, the corresponding workpiece seat 31 is selected and installed on the guide plate 3. During detection, turn on the click switch 61, and control the rotation speed of the detection head 7 through the speed regulator 62. Place the workpiece 9 on the workpiece seat 31, press the guide plate 3, so that the workpiece 9 approaches the detection head 7. When the first thread of the internal thread of the workpiece 9 enters the detection head 7, since the detection head 7 always maintains a right-handed state, the threads interact with each other after contacting the internal thread of the workpiece 9, and the spiral motion is converted into a straight downward motion of the guide plate 3. At this time, the torque sensor 5 detects the torque. If the actual torque measured is less than or greater than the set value range of 1.5 to 2.5 Nm, the product is considered unqualified and the equipment will alarm. If the workpiece 9 is stuck during the detection process, the reverse button can be manually pressed to withdraw the workpiece 9 from the detection and move it to the defective product box.

[0028] When the bottom surface of the guide plate 3 contacts the top surface of the in-position sensor 8, the main motor is triggered to reverse, and the internal thread of the workpiece 9 is rotated in the opposite direction by the detection head 7, driving the guide plate 3 to move upward, thereby pushing out the detection head 7. When the workpiece 9 is separated from the detection head 7, the torque value collected by the torque sensor 5 is an idling value, and the system can control the motor 6 to rotate forward, waiting for the next workpiece 9 to be detected. At this time, the thread detection has been completed, and the worker can remove the workpiece 9 and place it in a qualified product box for packaging and sealing. In the above process, the cylinder 44 and the spring 43 cooperate with each other to assist the guide plate 3 to balance the force and ensure that the detection is not disturbed by vibration or other external factors.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Without departing from the spirit and scope of the present invention, modifications or equivalent replacements of the present invention should be included in the scope of protection of the claims of the present invention.
