Description

Technical Field

[0001] The utility model relates to the technical field of equipment for single-piece and small-batch testing of springs, and specifically to an equipment for single-piece and small-batch testing of springs. Background Technique

[0002] The equipment for single-piece and small-batch testing of springs is a device for detecting the tensile and compressive forces of springs to determine whether the springs meet the production requirements.

[0003] For example, a spring testing machine with the publication number of "CN106840631A". A left test spring is installed between the left compression shaft and the left limiter, and a right test spring is installed between the right compression shaft and the right limiter; the rotating eccentric wheel drives the left compression shaft and the right compression shaft to periodically compress the left test spring and the right test spring. The left and right test springs are installed independently and the fatigue tests are carried out synchronously. This makes the spring testing machine of the present invention not only able to test two springs simultaneously, but also support testing springs of different models at the same time. However, in the use of the equipment for spring testing, although the simultaneous testing of two springs is achieved, the fixing form of the springs is relatively troublesome, and it takes time to replace after the spring testing, which increases the difficulty of using the equipment for spring testing and reduces the working efficiency of the equipment for spring testing. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems of increasing the difficulty of using the equipment for spring testing and reducing the working efficiency of the equipment for spring testing, and to propose an equipment for single-piece and small-batch testing of springs.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] Design an equipment for single-piece and small-batch testing of springs, including a chassis and a cross plate. The top of the chassis is fixedly connected to the bottom of the cross plate. The top of the cross plate is fixedly connected with top frames on the left and right sides. The top of the chassis is connected with a control structure. The top of the right side of the top frame is connected with a stretching structure. The bottom of the left and right sides of the chassis is respectively fixedly connected with bottom plates. The top of the right side of the cross plate is fixedly connected with a second hook.

[0007] Preferably, the control structure includes a screw rod and a handle. The outer wall of the screw rod is threadedly connected to the left side of the top of the chassis. The bottom of the screw rod is fixedly connected to the top of the handle. The top of the outer wall of the screw rod is rotatably connected with a straight plate. The left and right sides of the top of the straight plate are respectively fixedly connected with vertical plates. The top of the vertical plate is fixedly connected with a round rod. The end of the outer wall of the round rod is slidably connected with a concave plate. The top of the concave plate is fixedly connected with a curved block.

[0008] Preferably, the outer wall of the curved block is slidably connected to the notch on the left side of the top of the cross plate.

[0009] Preferably, a second cylinder is fixedly connected to the left side of the top of the top frame.

[0010] Preferably, a disc is fixedly connected to the output end of the second cylinder.

[0011] Preferably, the stretching structure includes a first cylinder and a round block. The outer wall of the first cylinder is fixedly connected to the right side of the top of the top frame. The output end of the first cylinder is fixedly connected to a round block, and a first hook is fixedly connected to the bottom of the round block.

[0012] An equipment for small-batch spring single-piece sampling proposed by the present utility model has the beneficial effects that: the lower part of the inner wall of the spring in the control structure is inserted into the outer wall of the curved block, and then the handle drives the screw rod to rotate downward through the bottom frame. The rotating screw rod drives the straight plate to move downward, and the moving straight plate cooperates with the vertical plate to drive the round rod to move downward. Due to the positioning of the vertical plate on the round rod, when the round rod slides in the inclined groove on the outer wall of the concave plate, the concave plate will move outward. The moving concave plate drives the curved block at the top to move outward, so that the curved block supports and fixes the inner wall of the spring, changing the original multi-point fixing form, reducing the use difficulty of the spring sampling equipment, and improving the working efficiency of the spring sampling equipment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be further described below with reference to the drawings:

[0019] Embodiment 1:

[0020] Please refer to Figures 1-4: In this embodiment, a device for small-batch spring single-piece testing includes a chassis 1 and a cross plate 4. The top of the chassis 1 is fixedly connected to the bottom of the cross plate 4. On the top of the cross plate 4, top frames 5 are fixedly connected to the left and right sides. A control structure 2 is connected to the top of the chassis 1. On the top right side of the top frame 5, a stretching structure 3 is connected. On the bottom of the left and right sides of the chassis 1, bottom plates 8 are respectively fixedly connected. On the front and back sides of the top of the bottom plate 8, threaded ports are respectively machined. On the top right side of the cross plate 4, a second hook 9 is fixedly connected.

[0021] The control structure 2 includes a screw rod 201 and a handle 202. The outer wall of the screw rod 201 is threadedly connected to the left side of the top of the chassis 1. The bottom of the screw rod 201 is fixedly connected to the top of the handle 202. The handle 202 facilitates turning the screw rod 201 up and down through the round opening on the left side of the top of the chassis 1. The top of the outer wall of the screw rod 201 is rotatably connected to a straight plate 203. The top of the outer wall of the screw rod 201 rotates through the bearing on the inner wall of the straight plate 203 when force is applied. On the left and right sides of the top of the straight plate 203, vertical plates 204 are respectively fixedly connected. On the top of the vertical plates 204, round rods 205 are fixedly connected. The outer end of the outer wall of the round rod 205 is slidably connected to a concave plate 206. The round rod 205 slides through the inclined groove on the outer wall of the concave plate 206 when force is applied. On the top of the concave plate 206, a curved block 207 is fixedly connected. The outer wall of the curved block 207 is slidably connected to the notch on the left side of the top of the cross plate 4. The curved block 207 slides left and right inside the notch on the left side of the top of the cross plate 4 when force is applied.

[0022] By inserting the lower part of the inner wall of the spring in the control structure 2 into the outer wall of the curved block 207, then turning the screw rod 201 downward through the chassis 1 with the handle 202, the rotating screw rod 201 drives the straight plate 203 to move downward. The moving straight plate 203 cooperates with the vertical plates 204 to drive the round rod 205 to move downward. Due to the positioning of the vertical plates 204 on the round rod 205, when the round rod 205 slides in the inclined groove on the outer wall of the concave plate 206, the concave plate 206 will move outward. The moving concave plate 206 drives the curved block 207 at the top to move outward, so that the curved block 207 supports and fixes the inner wall of the spring, changing the original multi-point fixing form, reducing the use difficulty of the spring testing device, and improving the working efficiency of the spring testing device.

[0023] On the top left side of the top frame 5, a second cylinder 6 is fixedly connected. The model of the second cylinder 6 is selected according to the use requirements. The output end of the second cylinder 6 is fixedly connected to a disc 7. The stretching structure 3 includes a first cylinder 301 and a round block 302. The outer wall of the first cylinder 301 is fixedly connected to the top right side of the top frame 5. The model of the first cylinder 301 is selected according to the use requirements. The output end of the first cylinder 301 is fixedly connected to a round block 302. The bottom of the round block 302 is fixedly connected to a first hook 303.

[0024] Working principle:

[0025] Make the bottom of the bottom plate 8 fit with the top of the external beam slab, and then the bolt is threaded through the bottom plate 8 from top to bottom and fixed to the beam slab.

[0026] Equipment compression test of single-piece small-batch spring samples:

[0027] Insert the lower part of the inner wall of the spring on the outer wall of the curved block 207. Then, turn the screw rod 201 downward through the base frame 1 by means of the handle 202. The rotating screw rod 201 drives the straight plate 203 to move downward. The moving straight plate 203 cooperates with the vertical plate 204 to drive the round rod 205 to move downward. Due to the positioning of the vertical plate 204 on the round rod 205, when the round rod 205 slides in the inclined groove on the outer wall of the concave plate 206, the concave plate 206 will move outward. The moving concave plate 206 drives the curved block 207 at the top to move outward, so that the curved block 207 supports and fixes the inner wall of the spring. Then, the working output end of the second cylinder 6 drives the disc 7 to move downward, so that the disc 7 compresses the spring. At this time, check the scale on the left side of the inner wall of the top frame 5 to see if the spring can be compressed to the specified scale.

[0028] Equipment tensile test of single-piece small-batch spring samples:

[0029] Hang the lower part of the outer wall of the spring on the second hook 9, and hang the upper part of the outer wall of the spring on the first hook 303. Then, the working output end of the first cylinder 301 drives the round block 302 and the first hook 303 to move upward to stretch the spring. At this time, check the scale on the right side of the inner wall of the top frame 5 to observe whether the spring reaches the specified tensile scale.

[0030] Embodiment 2:

[0031] Please refer to Figures 1-4 : In this embodiment, a device for single-piece small-batch spring samples further includes a vertical rod 10. The tops of the two vertical rods 10 are respectively fixedly connected to the left and right sides of the bottom of the straight plate 203. The outer wall of the vertical rod 10 is slidably connected to the circular opening on the outer wall of the base frame 1.

[0032] Working principle:

[0033] When the straight plate 203 moves up and down, it will drive the vertical rod 10 to slide up and down through the circular opening on the outer wall of the bottom plate 1. The vertical rod 10 plays a limiting role on the straight plate 203 to prevent the straight plate 203 from rotating.

[0034] Although the present utility model has been illustrated and described by reference to the preferred embodiments, those of ordinary skill in the art should understand that various changes in form and details can be made within the scope of the claims.
