[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0021] like Figures 1-2 The switch machine diode rectifier stack testing device shown includes a base 1 and an adjustment assembly 9. A placement frame 2 is fixedly connected to the base 1. The top of the placement frame 2 has multiple equidistantly arranged placement slots 3, and a mounting block 5 is provided on the upper side of the placement frame 2. An electric push rod 4 is fixedly connected to the top of the base 1. The output end of the electric push rod 4 is connected to the mounting block 5. A power supply is fixedly connected inside the mounting block 5, and multiple conductive rods 6 are fixedly connected to both ends of the mounting block 5. The conductive rods 6 are connected to the power supply. The outer end of the base 1 is mounted with... There are multiple indicator lights 7, which are connected to multiple conductive rods 6 respectively. Detection blocks 8 are provided on both sides of the outer end of the conductive rods 6. The bottom end of the mounting block 5 is slidably connected to the fixing plate 10, and multiple springs 12 are fixedly connected between the mounting block 5 and the fixing plate 10. The detection block 8 includes a limiting block 81 and an abutting block 82. The limiting block 81 and the abutting block 82 are integrally formed. The limiting block 81 is set as a ring structure and is sleeved on the outer end of the conductive rod 6. The bottom of the abutting block 82 is set as a long strip structure.

[0022] A switch machine is a device used to control the turning of railway turnouts, and a diode rectifier is a key component of it, used to convert alternating current into direct current. A diode rectifier is usually composed of multiple diodes connected in series or parallel to achieve higher voltage tolerance and / or higher current capacity. When the diodes leave the factory, they need to be tested for power-on, usually by applying a specified voltage across the diode or by using a multimeter to check whether a single diode is energized and illuminated, to prevent the diodes from not being energized.

[0023] The following are the detailed steps for testing a diode using the method of applying positive and negative voltages simultaneously:

[0024] 1. Insert the diode into the test circuit, make sure the connection is correct, that is, the positive electrode is connected to the positive voltage source, and the negative electrode is connected to the negative voltage source; 2. Set the voltage source to an appropriate voltage range, usually the rated operating voltage of the diode; 3. Apply a forward voltage (positive electrode connected to P-type material end), observe whether the diode is conducting; 4. Apply a reverse voltage (positive electrode connected to N-type material end), observe whether the diode is cut off (not conducting), under normal circumstances, when a forward voltage is applied, the diode should conduct; when a reverse voltage is applied, the diode should be cut off, if the diode conducts under both forward and reverse voltages, it may indicate that the diode is damaged or is another type of component.

[0025] In this scheme, the conductive rods 6 on both sides of the mounting block 5 are connected to the positive and negative electrodes of the power supply, respectively. The user places multiple diodes in the multiple placement grooves 3, respectively, and ensures that the multiple diodes are aligned, with the P-type material end or the N-type material end on the same side. Then the user starts the electric push rod 4 to move downward, and the fixing plate 10 will first abut against the multiple diodes, causing the multiple diodes to be squeezed by the soft pad 11. This not only fixes the diodes, but also avoids damaging them. As the mounting block 5 continues to move downward, the fixing plate 10 will slide on the mounting block 5 and squeeze the multiple springs 12. When the multiple abutting blocks 82 respectively abut against both ends of the multiple conductive rods 6, the user stops the movement of the mounting block 5. The limiting blocks 81 and the abutting blocks 82 are made of conductive material. The abutting blocks 82 can guide the positive and negative voltages to the two ends of the diodes. The abutting blocks 82 in strip structure improve the area of their bottom ends, ensuring smooth abutment with the diodes. Then the user can complete the detection of the diodes by observing whether the indicator lights 7 on both sides of the mounting block 5 are on, because under the condition that the diodes are of good quality, the forward voltage will conduct with the diodes, and the current will conduct to the indicator lights 7 to make them on. The reverse voltage will not conduct with the diodes, and the corresponding indicator lights 7 will not be on. In this way, the unified fixing and detection of multiple diodes can be quickly realized.

[0026] As shown in Figures 2-3 The bottom end of the fixing plate 10 is covered with a soft pad 11. The multiple placement grooves 3 correspond one-to-one with the multiple abutting blocks 82. The adjusting assembly 9 includes a pair of brackets 91, which are respectively arranged on both sides of the mounting block 5. The multiple limiting blocks 81 are fixedly connected with the brackets 91. The brackets 91 are made of insulating material. One end of each of the pair of brackets 91 is fixedly connected with a gear rack 92. The pair of gear racks 92 penetrates the mounting block 5 and is in sliding connection with the mounting block 5. The adjusting assembly 9 further includes a gear wheel 93, the top end of which is fixedly connected with a knob 94, which is in rotational connection with the mounting block 5. The pair of gear racks 92 is centrally symmetrically arranged and in meshing connection with the gear wheel 93.

[0027] In the scheme, when detecting diodes of different sizes, the distance between the two detection blocks 8 needs to be adjusted to ensure that the abutting blocks 82 can abut the two ends of the diode. At this time, the user can rotate the knob 94 to drive the gear 93 to rotate before detection, drive a pair of racks 92 to move through the gear 93, and then force a pair of supports 91 to slide the limiting blocks 81 on the conductive rod 6, so that the abutting blocks 82 on both sides move towards each other or away from each other, achieving adjustment of the distance therebetween. The support 91 is made of insulating material, which can prevent the current on the plurality of conductive rods 6 from being conducted to each other through the support 91.

[0028] The specific implementation process is as follows:

[0029] When detecting, the user places a plurality of diodes in the plurality of placement grooves 3 respectively, and ensures that the plurality of diodes are aligned, and the P-type material end or the N-type material end is at the same side. Then the user starts the electric push rod 4 to move downward, and the fixed plate 10 will abut the plurality of diodes first, and the plurality of diodes will be squeezed by the soft pad 11 to fix the diodes. As the mounting block 5 continues to move downward, the fixed plate 10 will slide on the mounting block 5 and squeeze the plurality of springs 12, until the abutting blocks 82 respectively abut the two ends of the plurality of conductive rods 6, the user stops the movement of the mounting block 5, and the positive and negative voltages are guided to the two ends of the diode through the abutting blocks 82, and then the user can complete the detection of the diode by observing whether the indicator lights 7 on both sides of the mounting block 5 are lit. If the diode is of good quality, the forward voltage will be conducted with the diode, and the current will be conducted to the indicator light 7 to make it light up, and the reverse voltage will not be conducted with the diode, and the corresponding indicator light 7 will not light up. When detecting diodes of different sizes, the user can rotate the knob 94 to drive the gear 93 to rotate before detection, drive a pair of racks 92 to move through the gear 93, and then force a pair of supports 91 to slide the limiting blocks 81 on the conductive rod 6, so that the abutting blocks 82 on both sides move towards each other or away from each other, achieving adjustment of the distance therebetween.

[0030] The above is only an embodiment of the present application, and the specific technical solutions and / or common knowledge of the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
