Description
Technical Field
[0001] The utility model belongs to the technical field of resistor production, and particularly relates to a detection device for resistor production. Background Art
[0002] A resistor is a current-limiting component. Resistors usually play the roles of voltage division and current shunting in a circuit. The resistance value of a resistor is fixed, generally with two leads. It can limit the magnitude of the current passing through the branch it is connected to. An ideal resistor is linear, that is, the instantaneous current passing through the resistor is proportional to the applied instantaneous voltage. The resistance value of a resistor element is generally related to temperature, material, length, and cross-sectional area. Therefore, during the production and processing of resistors, it is necessary to detect their resistance performance.
[0003] Existing detection devices usually connect the two leads of a resistor to a resistor tester. The resistor detector can detect various performance parameters of the resistor. Due to the lack of an effective fixing device for the resistor, it is prone to movement and offset, unable to maintain the stability of the resistor, with low work efficiency and affecting the detection effect. Summary of the Utility Model
[0004] In view of the above situation, to overcome the defects of the prior art, the purpose of the present utility model is to provide a detection device for resistor production, effectively solving the problems of poor fixing effect of the resistor and affecting the detection efficiency.
[0005] The technical solution for solving the technical problem is: It includes a workbench, on which a first baffle is slidably connected left and right. A second baffle is fixed on the workbench on the right side of the first baffle. A resistor is placed on the workbench between the first baffle and the second baffle. The resistor is provided with a first lead and a second lead. A plurality of guide rails are fixed on the workbench. A first bracket and a second bracket are slidably connected back and forth on the guide rails. The first bracket and the second bracket are symmetrically arranged back and forth about the middle position of the resistor. A first compression spring is sleeved on the guide rail between the first bracket and the second bracket. The first bracket is fixedly connected to a first base, and a first detection contact is telescopically connected back and forth in the first base on the front side of the first lead. The second bracket is fixedly connected to a second base, and a second detection contact is telescopically connected back and forth in the second base on the rear side of the second lead.
[0006] Preferably, a screw rod is rotatably connected to the workbench. The screw rod is threadedly connected to a nut. The upper end of the nut is fixedly connected to the lower end of the first baffle. A horizontal sliding groove is provided on the workbench, and the nut slides left and right in the sliding groove.
[0007] Preferably, a screw rod is rotatably connected to the workbench. The screw rod is threadedly connected to a nut. The upper end of the nut is fixedly connected to the lower end of the first baffle. A horizontal sliding groove is provided on the workbench, and the nut slides left and right in the sliding groove.
[0008] Preferably, limiting blocks are fixed on the workbench at the front and rear ends of the resistor.
[0009] Preferably, conical holes are provided in both the first detection contact and the second detection contact.
[0010] Preferably, a second compression spring is installed between the first base and the first detection contact, and a third compression spring is installed between the second base and the second detection contact.
[0011] The utility model has the following advantages compared with traditional devices: 1) The screw-nut structure is adopted to cleverly control the left and right sliding of the first baffle, adjust the distance between the first baffle and the second baffle, which is beneficial to loosen or clamp the resistor in the left and right directions, and combined with the limiting blocks in the front and rear directions, the positioning of the resistor in the front, rear, left and right directions is realized, the fixing effect is good, safe and stable, and the operation is simple; 2) Good linkage performance. By manually clamping the first bracket and the second bracket, the first detection contact and the second detection contact are synchronously moved closer to the resistor. The first detection contact is connected to the first lead wire, and the second detection contact is connected to the second lead wire. Under the action of the second compression spring, the first detection contact has elasticity in the first base, and under the action of the third compression spring, the second detection contact has elasticity in the second base, which has a buffering and protecting effect, and at the same time ensures that the first lead wire and the second lead wire are synchronously clamped and connected, with high working efficiency, safe and stable; 3) The conical hole structure is adopted, which helps the first lead wire or the second lead wire to be inserted into the internal part of the conical hole, and at the same time ensures the contact effect between the first lead wire and the first detection contact, and between the second lead wire and the second detection contact, and the power-on effect is good.

Detailed Embodiment
[0017] The following further elaborates on the specific implementation manners of the present utility model in conjunction with the accompanying drawings.
[0018] As shown by Figures 1 to 4 Figures 1 to 4
[0019] To ensure the stability of the left - right sliding of the first baffle 2 on the workbench 1, the workbench 1 is rotatably connected with a screw rod 15, the screw rod 15 is threadedly connected with a nut 16, the upper end of the nut 16 is fixedly connected with the lower end of the first baffle 2, and a horizontal sliding groove 17 is provided on the workbench 1, and the nut 16 slides in the left - right direction in the sliding groove 17.
[0020] To facilitate the positioning of the front and rear ends of the resistor 4, the workbench 1 is fixedly provided with limit blocks 18 at the front and rear ends of the resistor 4.
[0021] To facilitate the insertion of the first lead 5 into the first detection contact 12 and the second lead 6 into the second detection contact 14, conical holes 19 are provided in both the first detection contact 12 and the second detection contact 14.
[0022] To ensure the front - rear telescopic movement of the first detection contact 12 in the first base 11 and the front - rear telescopic movement of the second detection contact 14 in the second base 13, a second compression spring 20 is installed between the first base 11 and the first detection contact 12, and a third compression spring is installed between the second base 13 and the second detection contact 14.
[0023] When the utility model is in use, the first detection contact 12 and the second detection contact 14 are respectively connected to a resistance tester through wires. The resistance tester is an existing device. The resistor 4 is placed on the workbench 1. The resistor 4 is located within the limit blocks 18 on the front and rear sides. The limit blocks 18 effectively limit the front and rear ends of the resistor 4. Rotate the screw 15. The screw 15 drives the nut 16 to slide rightward in the sliding groove 17. The nut 16 drives the first baffle 2 to slide rightward. The first baffle 2 squeezes the resistor 4 rightward, and then clamps and fixes the resistor 4 between the first baffle 2 and the second baffle 3. Stop rotating the screw 15. Rubber pads corresponding to the resistor 4 are fixed on both the first baffle 2 and the second baffle 3, which plays a good protective role for the resistor 4.
[0024] The staff synchronously clamps the first bracket 8 and the second bracket 9 by hand. The first compression spring 10 is in a compressed state. The first bracket 8 drives the first base 11 and the first detection contact 12 to approach the first lead 5. The first lead 5 is inserted into the conical hole 19 inside the first detection contact 12. The diameter of the conical hole 19 decreases sequentially from the outside to the inside, ensuring that the first lead 5 and the first detection contact 12 are connected. The second bracket 9 synchronously drives the second base 13 and the second detection contact 14 to approach the second lead 6. The second lead 6 is inserted into the conical hole 19 inside the second detection contact 14. The diameter of the conical hole 19 decreases sequentially from the outside to the inside, ensuring that the second lead 6 and the second detection contact 14 are connected. Under the action of the second compression spring 20 and the third compression spring, the first detection contact 12 and the second detection contact 14 have a certain elasticity, which not only ensures the contact effect between the first lead 5 and the first detection contact 12 and the contact effect between the second lead 6 and the second detection contact 14, but also avoids damage to the resistor 4. At this time, the resistance tester can display various performance parameters of the resistor 4. Release the first bracket 8 and the second bracket 9. Under the action of the first compression spring 10 resetting, the first bracket 8 and the second bracket 9 are reset. The first detection contact 12 moves away from the first lead 5, and the second detection contact 14 moves away from the second lead 6. Reverse the screw 15. The screw 15 drives the nut 16 and the first baffle 2 to slide leftward and reset, and then the resistor 4 can be replaced. The operation is simple, safe and stable.

Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model all belong to the protection scope of the technical solution of the present utility model.
