For example, it can be a fixed connection, a detachable connection, an interference fit, a transition fit and other limit connections, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium; therefore, for those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.
[0031] The embodiment of the present application discloses an efficient and fast filter component test fixture. Refer to Figure 1, including a rectangular mounting table 1, on which multiple clamping assemblies 2 are arranged. In this embodiment, four clamping assemblies 2 are arranged, and the four clamping assemblies 2 are respectively arranged around the mounting table 1. The clamping assembly 2 includes a mounting plate 201 fixed on one side of the mounting table 1, a clamping spring 202 fixed on the side of the mounting plate 201 facing the mounting table 1, and a clamping plate 203 fixed on the side of the clamping spring 202 away from the mounting plate 201. The clamping spring 202 drives the clamping plate 203 to slide towards the center of the mounting table 1. The circuit board can be clamped by the four clamping plates 203. The sliding setting of the clamping plate 203 in cooperation with the clamping spring 202 can facilitate the clamping of circuit boards of different sizes. At the same time, the elastic force of the clamping spring 202 can reinforce the circuit board; a guide rod 3 is fixed on the side of the clamping plate 203 facing the mounting plate 201. One end of the guide rod 3 away from the clamping plate 203 penetrates through the mounting plate 201 and slides on the mounting plate 201. The clamping spring 202 is sleeved outside the guide rod 3. The guide rod 3 guides the sliding of the clamping plate 203, reducing the probability of bending and deflection of the clamping spring 202; through holes 4 are opened on the guide rod 3. By penetrating through the guide rod 3 and the clamping plate 203, there are various types of circuit boards. The wiring part of some circuit boards is just located in the clamping area of the clamping plate 203. The opening of the through holes 4 can be used for threading wires, facilitating the connection of the wires to the wiring part of the circuit board. A chamfer 5 is opened on the side of the clamping plate 203 facing away from the mounting table 1. When the circuit board is installed, it drives the clamping plate 203 to slide by abutting against the chamfer 5, thus facilitating the installation of the circuit board.
[0032] Refer to Figure 1 and Figure 2 , on the side of the mounting table 1 opposite to the clamping assembly 2, four placement blocks 6 are arranged. The four placement blocks 6 are respectively fixed at the four corners of the mounting table 1. The placement blocks 6 are used to support the mounting table 1, facilitating the placement of the mounting table 1 on the ground or the installation on the workbench. Mounting holes 7 are opened on the mounting table 1, and the mounting holes 7 penetrate through the mounting table 1 and the placement blocks 6. The setting of the mounting holes 7 facilitates the installation of bolts when the mounting table 1 needs to be fixed by bolts.
[0033] Refer to Figure 2 and Figure 3, a clamping member 8 is provided on the mounting table 1. The clamping member 8 includes a clamping plate 801 provided on the mounting table 1, a fixing plate 802 fixed at one end in the length direction of the clamping plate 801, and a sliding plate 803 slidably arranged on the clamping plate 801. A driving lead screw 9 is rotatably arranged on the clamping plate 801. The driving lead screw 9 is threadedly connected to the sliding plate 803. By rotating the lead screw, the sliding plate 803 is driven to slide towards or away from the fixing plate 802. Through the sliding of the sliding plate 803 and the cooperation of the fixing plate 802, chips of different sizes can be clamped. Rubber pads 10 are provided on the opposite sides of the fixing plate 802 and the sliding plate 803 facing each other. The setting of the rubber pads 10 can reduce the force exerted on the chip due to clamping through deformation when the sliding plate 803 and the fixing plate 802 clamp the chip, and can also reduce the probability of the chip detaching from the clamping member 8 through deformation. An adjusting mechanism 11 is provided between the clamping member 8 and the mounting table 1. The clamping member 8 slides on the mounting table 1 along the upper surface of the mounting table 1 through the adjusting mechanism 11 and is adjusted to any position on the mounting table 1 by sliding. At the same time, the adjusting mechanism 11 can also drive the clamping member 8 to slide towards or away from the mounting table 1, so as to adjust the height of the clamping member 8 according to chips of different thicknesses.
[0034] Refer to Figure 1 and Figure 2, the adjusting mechanism 11 includes two mounting brackets 111 erected on the mounting table 1, a sliding bracket 112 slidably arranged between the two mounting brackets 111, a lifting screw rod 113 slidably arranged on the sliding bracket 112, and a fixing nut 114 threadedly connected to the lifting screw rod 113. The two mounting brackets 111 are respectively erected at opposite ends of the mounting table 1. Trapezoidal chutes 12 penetrating through both ends in the length direction of the mounting bracket 111 are formed on the opposite sides of the two mounting brackets 111 facing each other. Trapezoidal sliders 13 are fixedly arranged at both ends in the length direction of the sliding bracket 112. The trapezoidal sliders 13 at both ends in the length direction of the sliding bracket 112 are respectively slidably arranged in the trapezoidal chutes 12 of the two mounting brackets 111. The sliding bracket 112 slides along the length direction of the mounting bracket 111 by sliding the trapezoidal sliders 13 in the trapezoidal chutes 12. A bolt is arranged between the sliding bracket 112 and the mounting bracket 111. The sliding bracket 112 can be fixed on the mounting bracket 111 by tightening the bolt. A sliding groove 14 is formed on the sliding bracket 112 along the length direction of the sliding bracket 112. The lifting screw rod 113 is installed in the sliding groove 14. The lifting screw rod 113 slides along the length direction of the sliding bracket 112 in the sliding groove 14 and slides towards or away from the mounting table 1 on the sliding bracket 112. There are two fixing nuts 114. The two fixing nuts 114 are respectively threadedly connected to the lifting screw rod 113 on both sides in the thickness direction of the sliding bracket 112. By rotating the two fixing nuts 114, the two fixing nuts 114 clamp both ends of the sliding bracket 112 to fix the lifting screw rod 113. By rotating the fixing nut 114 to adjust the position of the fixing nut 114 on the lifting screw rod 113, the height of the lifting screw rod 113 on the sliding bracket 112 is adjusted. The clamping plate 801 is fixedly arranged at one end of the lifting screw rod 113 facing the mounting table 1.
[0035] Refer to Figure 4 and Figure 5, a guide plate 15 is fixedly provided on the side of the clamping plate 203 facing the mounting plate 201. One end of the guide plate 15 away from the clamping plate 203 penetrates the mounting plate 201 and slides on the mounting plate 201. One side of the guide plate 15 abuts against the upper surface of the mounting table 1. A reinforcing component 16 is arranged on the mounting table 1. The reinforcing component 16 includes a driving slide rod 161 slidably inserted into the center of the mounting table 1, several linkage rods 162 respectively corresponding to several clamping components 2, and several abutting rods 163 corresponding to the linkage rods 162. In this embodiment, four linkage rods 162 are arranged corresponding to the clamping components 2. One end of the driving slide rod 161 in the length direction is conical. The conical end of the driving slide rod 161 is inserted into the mounting table 1 and slides along the thickness direction of the mounting table 1. Wedge-shaped surfaces 17 are provided at both ends of the linkage rod 162 in the length direction. One end of the linkage rod 162 abuts against the conical end of the driving slide rod 161. The abutting rod 163 abuts against one end of the corresponding linkage rod 162 away from the driving slide rod 161. When the driving slide rod 161 slides towards the inside of the mounting table 1, it drives the linkage rod 162 to slide away from the driving slide rod 161. The linkage rod 162 drives the abutting rod 163 to slide out of the mounting table 1 and abut against the guide plate 15, applying a force to the guide plate 15, thereby restricting the sliding of the guide plate 15 and realizing the reinforcement of the clamping plate 203, reducing the probability of the clamping plate 203 sliding under external force; several sliding platforms 18 are slidably arranged in the mounting table 1 corresponding to the sliding of the linkage rods 162. In this embodiment, four sliding platforms 18 are arranged. The linkage rods 162 and the abutting rods 163 are both slidably arranged in the sliding platforms 18. A return spring 19 is arranged in the sliding platform 18. The return spring 19 drives the linkage rod 162 to slide towards the driving slide rod 161. One end of the mounting table 1 away from the clamping member 8 is detachably provided with a retaining piece 20. A tightening bolt 21 is threadedly arranged on the retaining piece 20. The tightening bolt 21 abuts against the sliding platform 18, so that the linkage rod 162 in the sliding platform 18 abuts against the driving slide rod 161. Rotating the tightening bolt 21 to make the tightening bolt 21 away from the sliding platform 18, the sliding platform 18 slides towards the direction away from the clamping member 8 under the action of gravity. At this time, the sliding platform 18 drives the linkage rod 162 and the abutting rod 163 to slide, so that the abutting rod 163 disengages from the guide plate 15, releasing the reinforcement of the clamping plate 203, thus facilitating the normal disassembly of the circuit board.
[0036] The implementation principle of the embodiment of this application is: install the mounting table 1 at the required position, install the circuit board between the four clamping plates 203. When the circuit board is installed, it drives the clamping plate 203 to slide, and then it is fixed between the four clamping plates 203 under the elastic force of the clamping spring 202. During this period, the circuit board abuts against the driving slide rod 161, causing the driving slide rod 161 to slide. By driving the sliding of the sliding rod, the linkage rod 162 is driven. The linkage rod 162 drives the abutting rod 163 to abut against the guide plate 15 to reinforce the clamping plate 203. Then, the chip is clamped by the clamping member 8, and the chip is adjusted to the required position through the adjusting mechanism 11, and the chip is tested to complete the temporary clamping for chip testing.
