Description
Technical Field
[0001] The utility model relates to the field of spring processing, and more particularly to a spring fixing assembly and a spring testing device. Background Art
[0002] A spring is a mechanical part that uses elasticity to work. It is generally made of spring steel. During the production process, in order to ensure quality, its tension needs to be tested.
[0003] Existing spring tension testing devices generally consist of a test device body, tension testing components, two sets of fixed components and a driving component that drives the fixed components to move. In the prior art, the fixed components are generally hooks. By setting two hooks to limit the two ends of the spring, the driving component drives one side of the hook to move away from the other side of the hook, thereby stretching the spring. In this process, the user evaluates the tension value of the spring through the tension testing components.
[0004] However, this test device with a hook as the fixing component is more suitable for testing springs that already have hooks. It is not ideal for testing springs that do not have hooks, and deformation, displacement, or even unhooking of both ends of the spring may occur.
[0005] Based on the above, the purpose of the present invention is to provide a spring fixing assembly and a spring testing device to solve the above problems. Utility Model Content
[0006] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide a spring fixing assembly and a spring testing device. The present invention arranges two relatively movable clamping blocks on a slide, and arranges insertion rods and liftable clamping blocks on the two side clamping blocks to fix different types of springs respectively. The insertion rods can be used to quickly connect springs with built-in hooks, and the pressure plates on both sides can be used to limit springs without hooks. The springs can also be combined and fixed by the above method to increase the stability of the fixation. The fixing assembly set in this way can adapt to a variety of different types of springs.
[0007] The above technical objectives of the present utility model are achieved through the following technical solutions: a spring fixing assembly, including a mounting plate, a slide is provided on the mounting plate, a sliding groove is provided on the slide, two clamping blocks are slidably connected in the sliding groove, a control mechanism is provided on the slide to drive the clamping blocks on both sides to move relative to each other, an insertion rod is provided between the clamping blocks on both sides, limiting grooves for inserting the insertion rod are provided on the clamping blocks on both sides, pressure blocks are provided on the clamping blocks on both sides, lifting grooves for inserting and moving the pressure blocks are provided on the clamping blocks, and a lifting mechanism is provided on the clamping blocks to drive the pressure blocks to move up and down.
[0008] By adopting the above technical solution, when it is necessary to connect the spring with its own hook, the control mechanism drives the two side clamps to move away from each other, so that a space sufficient for the spring hook to be inserted is formed between the two side clamps, and then the spring hook is inserted into this space, and then the insertion rod is inserted into the limit grooves on both sides, and then the hook is hung on the limit rod. When it is necessary to fix the spring without its own hook, the spring is placed between the two clamps, and then the control mechanism drives the two side clamps to gather inward until one end of the spring contacts the upper end surfaces of the two side pressure blocks, and the two sides of the lower end of the spring are respectively located in the two side pressure blocks, and then the two side pressure blocks are driven down by the lifting mechanism until this end of the spring is pressed tightly between the two side clamps and the pressure blocks.
[0009] The utility model is further configured as follows: the control mechanism includes a bidirectional screw rod rotatably connected to the slide, the clamping blocks on both sides are respectively glued to the left-handed thread section of the bidirectional screw rod and threadedly connected to the right-handed thread section, and a hand wheel is fixedly connected to the bidirectional screw rod.
[0010] The utility model is further configured as follows: the lifting mechanism comprises a screw rod rotatably connected to the clamping block, the pressing block is threadedly connected to the screw rod, and a second hand wheel is fixedly connected to the screw rod.
[0011] The utility model is further configured as follows: the pressing block is configured in a barbed hook shape.
[0012] The utility model is further configured as follows: clamping grooves are provided on the clamping blocks on both sides, and the cross section of the clamping grooves is triangular.
[0013] The utility model is further configured as follows: a plurality of limiting grooves are provided and are respectively distributed in an array on the pressing block.
[0014] The utility model is further configured as follows: a magnetic attraction piece is provided on the insertion rod.
[0015] The utility model is further configured as follows: the slide is rotatably connected to the mounting plate.
[0016] The utility model also provides a spring testing device, which comprises a testing device body, a tension testing component, two sets of fixing components and a driving component for driving the fixing components to move.
[0017] Since the above-mentioned fixing assembly has the technical effect of the above-mentioned spring fixing assembly, the spring testing device having the fixing assembly also has the same technical effect.
[0018] In summary, the present invention has the following beneficial effects:
[0019] The utility model arranges two relatively movable clamping blocks on a slide, and arranges insertion rods, clamping grooves and liftable clamping blocks on the clamping blocks on both sides to fix different types of springs respectively. The insertion rods can be used to quickly connect springs with built-in hooks, and the slide can be rotated to facilitate the connection of the insertion rods with hooks at different angles. The pressure plates on both sides can be used to limit springs without hooks, and the pressure grooves can be used to clamp springs with straight rods. The springs can also be combined and fixed by the above method to increase the stability of the fixation. The fixing components set in this way can adapt to a variety of different types of springs.

[0029] The present invention will be described in detail below with reference to the accompanying drawings.
[0030] A spring fixing assembly, such as Figure 1 and Figure 2 As shown, the device comprises a mounting plate 1, rotatably connected to a slide 2. The slide 2 defines a sliding groove 3, within which two clamping blocks 4 are slidably connected. Each clamping block has a clamping groove 12, each with a triangular cross-section. The slide 2 is provided with a control mechanism that drives the clamping blocks 4 relative to each other. The control mechanism comprises a bidirectional screw 8, which is rotatably connected to the slide 2. The clamping blocks 4 are respectively glued to the left-handed threaded section of the bidirectional screw 8 and threadedly connected to the right-handed threaded section. A handwheel 9 is fixedly connected to the bidirectional screw 8.
[0031] A rod 5 is positioned between the two clamping blocks 4, and a magnetic element 13 is mounted on the rod 5. Both clamping blocks are made of metal that can be attracted by the magnetic element 13. Each clamping block 4 has multiple retaining slots 6 for the rod 5 to be inserted into. Each clamping block 4 also has a pressure block 7, which is designed in a barbed shape. Each clamping block 4 has a lifting slot for the pressure block 7 to be inserted and moved. The clamping block 4 is equipped with a lifting mechanism that drives the pressure block 7 up and down. The lifting mechanism includes a screw 10 that is rotatably connected to the clamping block 4. The pressure block 7 is threadedly connected to the screw 10, and a handwheel 11 is fixedly connected to the screw 10.
[0032] When it is necessary to connect the spring 17 with its own hook, the bidirectional screw rod 8 is driven to rotate by the hand wheel 19, and the bidirectional screw rod 8 will drive the clamping blocks 4 on both sides to move away from each other, so that a space sufficient for the hook of the spring 17 to be inserted is formed between the clamping blocks 4 on both sides, and then the hook of the spring 17 is inserted into this space, and then the insertion rod 5 is inserted into the limiting groove 6 at the appropriate position on both sides according to the extension length of the spring 17 hook, and then the hook is mounted on the limiting rod.
[0033] When it is necessary to fix the spring 17 without its own hook, place the spring 17 between the two clamping blocks 4, and then drive the clamping blocks 4 on both sides to gather inward through the handwheel 1 9 and the two-way screw 8 until one end of the spring 17 contacts the upper end surface of the pressure blocks 7 on both sides, and the two sides of the lower end of the spring 17 are respectively stuck in the pressure blocks 7 on both sides, and then drive the screw 10 to rotate through the handwheel 2 11, thereby driving the pressure blocks 7 on both sides to descend until this end of the spring 17 is pressed tightly between the clamping blocks and the pressure blocks 7 on both sides.
[0034] When it is necessary to fix the spring 17 with straight rods at both ends, the straight rod of the spring 17 is inserted between the two clamping blocks 4, and then the clamping blocks 4 on both sides are driven inward by the handwheel 9 and the bidirectional screw 8 until the straight rod of the spring 17 is clamped in the pressure grooves on both sides.
[0035] The springs 17 can also be combined and fixed by the above method to increase the stability of the fixation. Such a fixing assembly can adapt to various types of springs 17.
