Description

Technical Field

[0001] The utility model relates to the technical field of socket production, and more specifically, to a socket stress testing machine for a socket. Background Art

[0002] A socket is a seat that can be plugged with one or more circuit wires. Various wires can be plugged into it to facilitate connection with other circuits. A power socket is an electrical device that provides a power interface for household appliances. It is also an electrical accessory that is used more frequently in residential electrical design. It is closely related to people's lives.

[0003] At present, in order to ensure that the stress of the socket is neither too large to make the plug difficult to insert, nor too small to cause loose contact between the plug and the socket, it is usually necessary to stress test the socket according to product usage requirements and industry standards. Through stress testing, potential risk points can be found, such as microcracks inside the material, solder joint damage, etc., so as to prevent and optimize them in the early stages of production. Therefore, a socket stress testing machine for sockets is needed to test the sockets.

[0004] At present, when conducting stress tests, the socket needs to be fixed under the plug to simulate the daily use environment. The force given by the testing machine is used to separate the plug and the socket. At this time, the automatic centering device in the testing machine will calculate the stress when the plug and the socket are plugged in and out. In order to align the plug and the socket and prevent them from being misaligned, it is usually necessary to use a screw to accurately calibrate the position of the socket. This will result in that when the deviation between the socket and the plug is large, due to the high precision of the screw, it takes a long time to rotate the screw to complete the calibration, which is time-consuming and labor-intensive, so it needs to be improved and optimized.

DETAILED DESCRIPTION

[0029] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figures 1 to 7 As shown, the utility model provides a socket stress tester for sockets, comprising a test machine base 1, two groups of guide rods 2 are fixedly installed on the top of the test machine base 1, a moving platform 3 is movably sleeved between the two groups of guide rods 2, a fixed platform 5 is movably installed between the two groups of guide rods 2, an automatic centering device 6 is fixedly installed at the bottom of the fixed platform 5, a base 7 is fixedly installed on the top of the moving platform 3, and an adjustment mechanism is fixedly installed on the top of the base 7;

[0031] There are two groups of adjustment mechanisms, including an adjustment chamber 8 fixedly installed on the top of the base 7, a first convex block 9 fixedly installed inside the adjustment chamber 8, a screw rod 10 rotatably installed inside the first convex block 9, a knob 11 rotatably installed on the left side of the adjustment chamber 8, the knob 11 and the screw rod 10 are fixedly connected, sliders 12 are movably installed on both sides of the screw rod 10, columns 13 are fixedly installed inside the two groups of sliders 12, and pressure blocks 14 are movably sleeved on the outer walls of the two groups of columns 13, the bottoms of the two ends of the pressure blocks 14 and the sliders 12 are elastically connected by springs 15, and the middle part of the pressure block 14 is threadedly connected to the screw rod 10;

[0032] A telescopic groove 16 is provided at the top of the two groups of sliders 12, and a pressure plate 17 is movably installed inside the telescopic groove 16. The front and rear sides of the pressure plate 17 and the pressure block 14 abut against each other. One end of the pressure plate 17 and the inner wall of the telescopic groove 16 are elastically connected by a spring 18. The pressure plate 17 is fixedly connected to a control plate 19, and the control plate 19 is located at the top of the slider 12.

[0033] When the socket needs to be stress tested, the staff needs to position the plug and the socket to prevent the two from being misaligned. When the deviation between the socket and the plug is large, the staff can move the pressure plate 17 through the control panel 19 to store the pressure plate 17 into the telescopic groove 16. At this time, the pressure block 14 that is abutted by the pressure plate 17 is lost, and its two ends will bounce upward along the column 13 through the elastic potential energy of the spring 15, so that the pressure block 14 moves upward. At this time, the staff loosens the control panel 19, and the bottom of the pressure block 14 and the screw 10 lose the threaded connection. At this time, the staff can first move the socket to the bottom of the plug. After the displacement is completed, the staff moves to The pressure block 14 is pressed down and can be adjusted left and right so that the bottom of the pressure block 14 and the screw 10 are meshed with each other. After the pressure block 14 is reset downward, the elastic potential energy of the spring 18 will drive the pressure plate 17 to move to the outside of the telescopic slot 16, and further make the pressure plate 17 fix the two ends of the pressure block 14 to prevent the pressure block 14 from popping out. At this time, the staff can use the knob 11 to rotate the screw 10 to accurately adjust the position of the socket. After the calibration of the plug and the socket is completed, the cylinder 4 operates to drive the moving platform 3 to move up and down along the guide rod 2, so that the plug and the socket can be plugged in and out multiple times. At this time, the automatic centering device 6 will calculate the stress of the socket to complete the test operation.

[0034] Through the contraction of the pressure plate 17, the two ends of the pressure block 14 will bounce upward along the column 13 through the elastic potential energy of the spring 15. At this time, the pressure block 14 can be pushed to slide along the slide groove 27 to preliminarily calibrate the positions of the plug and the socket. By pressing the pressure block 14 downward, the threaded connection relationship between the pressure block 14 and the screw rod 10 is restored, and the pressure block 14 is fixed. At this time, the position of the socket can be accurately calibrated by rotating the screw rod 10. Compared with the traditional device, the device can quickly adjust the position of the socket by pushing the pressure block 14. After the adjustment is completed, the position of the socket is finely calibrated by rotating the screw rod 10, which effectively improves the efficiency of calibration and adjustment.

[0035] Among them, the bottom of the automatic centering device 6 and the top of the upper pressure block 14 are fixedly installed with a clamping platform 20, a guide groove 21 is opened inside the clamping platform 20, and a screw rod 23 is rotatably installed inside the guide groove 21. Moving blocks 22 are movably installed on the left and right sides of the guide groove 21. The moving blocks 22 and the screw rod 23 are threadedly connected. One end of the two groups of moving blocks 22 is fixedly connected to the clamping plate 24, and a knob 26 is rotatably installed on the left side of the clamping platform 20, and the knob 26 and the screw 23 are fixedly connected.

[0036] It is worth mentioning that the model of the automatic centering device 6 is the automatic centering pneumatic chuck MA-10, which contains a hydraulic piston, a guide sleeve and a spindle pull rod. It is an existing technology and plays the role of automatically finding and correcting the center point of the workpiece before the test, thereby further making the stress test results of the socket more accurate.

[0037] When the socket needs to be stress tested, the staff first installs the socket and the plug, places the plug and the socket on one side of the clamping table 20, and turns knob 26. Knob 26 rotates to drive screw 23 to rotate. Since the threads on both sides of screw 23 are opposite and have the same pitch, the two groups of moving blocks 22 threadedly connected to screw 23 are synchronously displaced inwardly. Further, two groups of clamping plates 24 clamp the socket and the plug. At this time, the socket and the plug are both located in the center of the clamping table 20, which is convenient for the staff to position.

[0038] By rotating the knob 26, the screw 23 rotates. Since the threads on both sides of the screw 23 are opposite and have the same pitch, the two groups of moving blocks 22 threadedly sleeved with the screw 23 are synchronously displaced inward, and further two groups of clamping plates 24 clamp the socket and the plug. Compared with the traditional device, the device fixes the plug and the socket at the center position of the clamping table 20 through the setting of the screw 23, which is convenient for the staff to position the plug and the socket and improves the calibration efficiency.

[0039] A cylinder 4 is fixedly installed on the top of the test machine base 1 , and an output shaft of the cylinder 4 is fixedly connected to the moving platform 3 .

[0040] The cylinder 4 operates to drive the movable platform 3 to move up and down along the guide rod 2, so that the plug and the socket can be plugged in and out multiple times. At this time, the device will calculate the stress of the socket.

[0041] A slide groove 27 is provided between the two sides of the regulating chamber 8 and the first protrusion 9 , and the slider 12 is movably installed inside the slide groove 27 .

[0042] The adjusting mechanism has two groups, the top of the pressure block 14 in the lower adjusting mechanism is fixedly connected to the adjusting chamber 8 in the upper adjusting mechanism, and the pressure block 14 in the lower adjusting mechanism is fixedly connected to the clamping platform 20.

[0043] The two ends of the pressing block 14 are clamped in the interior of the sliding block 12 , and the two ends of the pressing block 14 abut against each other with the pressing plate 17 through the elastic potential energy of the spring 15 .

[0044] The elastic potential energy of the second spring 18 drives the pressing plate 17 to move outward from the telescopic slot 16 , and further enables the pressing plate 17 to fix the two ends of the pressing block 14 to prevent the pressing block 14 from popping out.

[0045] A second protrusion 25 is fixedly mounted on one side of the two sets of clamping plates 24 to prevent the socket from falling off.

[0046] The two groups of adjustment mechanisms are perpendicular to each other, and the lower adjustment mechanism is responsible for controlling the lateral displacement of the clamping platform 20 , while the upper adjustment mechanism is responsible for controlling the front and rear displacement of the clamping platform 20 .

[0047] Wherein, both left and right ends of the fixed platform 5 are fixedly provided with clamps 28 , and two sets of clamps 28 fix the fixed platform 5 to the outer wall of the guide rod 2 through fasteners 29 .

[0048] When encountering a larger plug and socket, the staff can move the fixed height of the fixing platform 5, and then fix the clamp 28 with the fastener 29 to fix the fixing platform 5 firmly.

[0049] The threads on the left and right sides of the second screw rod 23 are opened in opposite directions, and the pitches of the two sets of threads are the same.

[0050] Since the threads on both sides of the second screw rod 23 are opposite and have the same pitch, the two groups of moving blocks 22 threadedly sleeved with the second screw rod 23 are synchronously displaced inwards, and further two groups of clamping plates 24 clamp the socket and the plug.

[0051] The working principle and use process of this utility model:

[0052] When the socket needs to be stress tested, the staff first installs the socket and the plug, places the plug and the socket on one side of the clamping table 20, and turns knob 26. Knob 26 rotates to drive screw 23 to rotate. Since the threads on both sides of screw 23 are opposite and have the same pitch, the two groups of moving blocks 22 threadedly connected to screw 23 are synchronously displaced inwardly. Further, two groups of clamping plates 24 clamp the socket and the plug. At this time, the socket and the plug are both located in the center of the clamping table 20, which is convenient for the staff to position.

[0053] Then, the staff needs to position the plug and the socket to prevent the two from being misaligned. When the deviation between the socket and the plug is large, the staff can move the pressure plate 17 through the control panel 19 to retract the pressure plate 17 into the telescopic groove 16. At this time, the pressure block 14 that is abutted by the pressure plate 17 is lost, and its two ends will bounce upward along the column 13 through the elastic potential energy of the spring 15, causing the pressure block 14 to move upward. At this time, the staff loosens the control panel 19, and the bottom of the pressure block 14 and the screw 10 lose the threaded connection relationship. At this time, the staff can first move the socket to the bottom of the plug. After the displacement is completed, the staff presses the pressure block downward. 14, and can be adjusted left and right, so that the bottom of the pressure block 14 and the screw 10 are meshed with each other. After the pressure block 14 is reset downward, the elastic potential energy of the spring 2 18 will drive the pressure plate 17 to move to the outside of the telescopic slot 16, and further make the pressure plate 17 fix the two ends of the pressure block 14 to prevent the pressure block 14 from popping out. At this time, the staff can use the knob 11 to rotate the screw 10, so as to accurately adjust the position of the socket. After the calibration of the plug and the socket is completed, the cylinder 4 operates to drive the moving platform 3 to move up and down along the guide rod 2, so that the plug and the socket are plugged in and out multiple times. At this time, the automatic centering device 6 will calculate the stress of the socket to complete the test operation.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
