Description

Technical Field

[0001] This utility model relates to the field of motherboard circuit fault detection technology, specifically an auxiliary fixture for motherboard circuit fault detection. Background Technology

[0002] A motherboard circuit fault detection fixture is a fixture used to test whether the various functions of a motherboard are intact. This type of fixture integrates various test modules to simulate various usage scenarios of the motherboard after assembly, so as to achieve the purpose of real testing. In order to ensure the smooth and stable movement of the upper fixture, modern motherboard function test fixtures usually have a guide structure to guide the movement of the upper fixture. In order to buffer the movement of the upper fixture, springs are usually set on the guide structure.

[0003] In response, Chinese patent application number CN202320271663.1 discloses a motherboard function testing fixture, including a base, a bracket mounted on the base, a height adjustment mechanism mounted on the bracket, a push rod movable up and down via the height adjustment mechanism, an upper clamp at the end of the push rod, and a lower clamp mounted on the base and used in conjunction with the upper clamp. A guide structure connects the bracket and the base, and the upper clamp is threaded onto the guide structure and can slide back and forth along the length of the guide structure. The guide structure includes a guide rod and a bolt. The guide rod is connected to the bracket, and the bolt is threaded from bottom to top through the base and abuts against the end of the guide rod. A spring is sleeved on the guide structure at a position between the upper clamp and the base. This motherboard function testing fixture allows for easy replacement of the buffer spring, and its guide structure has a self-lubricating function.

[0004] The clamp uses bolts to restrict the spring to the outside of the guide rod. However, the bottom of the bolt is located inside the base, and the height of the inside of the base is limited. During disassembly and assembly, it is not convenient to place the bolt vertically inside the base. Furthermore, the upper end of the bolt abuts against the bottom end of the guide rod, resulting in a weak connection. When the bottom end of the guide rod shifts, the movement trajectory of the upper clamp shifts, affecting the coordination between the upper and lower clamps.

[0005] Therefore, in order to solve the above problems, an auxiliary fixture for motherboard circuit fault detection is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide an auxiliary fixture for motherboard circuit fault detection, in order to solve the problem mentioned in the background art that the fixture can restrict the spring to the outside of the guide rod by setting bolts, but the bottom end of the bolt is located inside the base. The height of the inner side of the base is limited, making it inconvenient to place the bolt vertically inside the base during disassembly and assembly. In addition, the upper end of the bolt abuts against the bottom end of the guide rod, resulting in weak connection strength. When the bottom end of the guide rod shifts, the movement trajectory of the upper fixture shifts, affecting the coordination of the upper and lower fixtures.

[0007] To achieve the above objective, the present utility model provides the following technical solution: an auxiliary fixture for motherboard circuit fault detection, comprising: a base, a bracket is installed on the top surface of the base, an air cylinder is installed on the front surface of the bracket, an extension end of the air cylinder is connected with an upper fixture, and an upper guide rod is connected to the inner wall of the bracket; a clamping groove is opened at the bottom end of the upper guide rod, and a mounting groove is opened on the top surface of the base; a mounting structure is installed on the base, the mounting structure comprises a mounting plate, the mounting plate is movably installed inside the mounting groove, a guide groove is opened on the outer wall of the mounting plate, a rectangular groove is opened at the front end of the top surface of the mounting plate, a collecting tray is placed at the front end of the top surface of the mounting plate, a lower guide post is inserted inside the rectangular groove, a clamping block is integrally formed at the upper end of the lower guide post, a spring is placed inside the collecting tray, and a bolt is inserted on the back surface of the mounting plate.

[0008] Preferably, the mounting plate is in a "匚"-shaped configuration, and the guide groove is clamped on the inner wall of the mounting groove.

[0009] Preferably, the collecting tray is located on the upper side of the rectangular groove, and the collecting tray communicates with the inside of the rectangular groove.

[0010] Preferably, the lower guide post penetrates the collecting tray, and the diameter of the lower guide post is the same as that of the upper guide rod.

[0011] Preferably, the clamping block is arranged in the front-rear direction, and the clamping block is clamped inside the clamping groove.

[0012] Preferably, the spring is sleeved on the outer side of the lower guide post.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: according to the present utility model, a mounting groove is opened on the top surface of the base, and a mounting plate capable of translating and moving is arranged in the mounting groove, so that the spring can be placed at the lower side of the upper guide rod at a horizontal angle when the spring is disassembled and assembled, which is convenient to operate; moreover, the clamping block can be clamped in the clamping groove, and the clamping block cooperates with the clamping groove to limit the bottom end of the upper guide rod at the lower side, which can maintain smooth transition between the upper guide rod and the lower guide post, and can improve the convenience of spring disassembly and assembly.

[0014] This utility model features an installation structure. A collection tray is mounted on the top front of a mounting plate. The bottom end of a lower guide post is inserted into the inner side of a rectangular groove, with the locking block positioned in a front-to-back direction. The lower guide post secures the collection tray to the top surface of the mounting plate. A spring is then fitted onto the outer side of the lower guide post, its bottom end locking into the inner side of the collection tray. The mounting plate is placed behind the mounting groove, aligning it front-to-back. The mounting plate is then inserted into the groove, where the guide post locks into the inner wall, ensuring vertical stability of the mounting plate within the groove. The locking block then engages forward within the locking groove. On the side, the locking block engages with the locking slot, allowing the bottom end of the upper guide rod to be limited by the lower guide post, ensuring the lower guide post remains vertical. Inserting the bolt into the back of the mounting plate and rotating it screws the bolt's tip into the inner wall of the mounting groove, ensuring stable mounting of the mounting plate within the groove. Injecting lubricating oil into the collection tray and activating the cylinder lowers the upper clamp, allowing it to slide stably on the upper guide rod. The upper clamp compresses the spring, immersing it in the lubricating oil in the collection tray. As the spring returns to its original position, the lubricating oil adhering to its surface coats the upper clamp, lower guide post, and upper guide rod, ensuring smooth movement of the upper clamp.
