Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a detection device for spring production. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force and return to their original shape after the external force is removed. They are generally made of spring steel. There are many types of springs. According to their shape, there are mainly coil springs, scroll springs, leaf springs, special-shaped springs, etc. During the spring production process, they must undergo rigorous testing before they can be put into use, including testing the compressive force of the spring through spring testing equipment.

[0003] When performing a spring pressure test, the spring is placed on the test bench, and the pressure detection device is used to transmit the force downward to contact and squeeze the spring to perform a compressive force test. However, since the spring is not fixed, if the force on the spring is uneven during the squeezing process, the spring is prone to tilt and deform, causing it to rebound and fly out of the pressure detection device, which not only affects the test results but also poses a safety hazard. Summary of the Invention

[0004] The purpose of the utility model is to provide a spring production detection device with high flexibility and high safety in order to solve the above problems in the prior art.

[0005] The purpose of this utility model can be achieved through the following technical solutions:

[0006] A testing equipment for spring production comprises a base, two support frames respectively fixedly connected to the upper parts of both ends of the base and a top plate fixedly connected to the upper parts of the two support frames, characterized in that it also comprises a lifting assembly, a pushing assembly and a positioning assembly, the above-mentioned support frame is C-shaped when viewed from above and the C-shaped recesses of the two support frames are arranged opposite to each other, the lifting assembly is arranged at the C-shaped recess and the upper and lower ends of the lifting assembly are respectively connected to the top plate and the base, the pushing assembly is arranged between the two support frames and the two ends of the pushing assembly are connected to the lifting assembly, and the pushing assembly can move up and down under the drive of the lifting assembly, the positioning assembly is arranged in the middle of the upper surface of the base and the two are movably connected, the positioning assembly and the pushing assembly are directly opposite to each other up and down, and the positioning assembly is used to place the spring.

[0007] This spring production testing equipment is used to perform pressure testing on springs. The base, support frame and top plate support the entire equipment. The front of the base can be used to install a control panel, and the upper part of the base forms a test bench. The positioning component is detachably connected to the test bench to place the spring to be tested, and the positioning component can be used to position springs of different sizes so that they are not easily popped out of the test bench. When in use, first place the spring to be tested steadily on the positioning component, start the lifting component, and the lifting component stably drives the pushing component to move downward. When the pushing component rests on the spring, it starts to squeeze the spring. During the squeezing process, the spring is evenly stressed, not easy to tilt and deform, and not easy to fly out of the test bench from the side, ensuring that the spring pressure test can be carried out smoothly, improving the accuracy of the final test result, and reducing the risk of the spring flying out and endangering human health.

[0008] In the above-mentioned spring production testing equipment, a recessed positioning groove is provided in the middle of the upper surface of the base, and the positioning groove matches the positioning assembly. The positioning assembly is embedded in the positioning groove and the upper surfaces of the two are flush with each other.

[0009] The positioning groove is used to install the positioning component. The positioning component is embedded in the positioning groove and is flush with the surface of the test bench, making the structure more compact.

[0010] In the above-mentioned spring production testing equipment, the positioning assembly includes several positioning seats, which are disc-shaped and have a concave positioning notch on the upper part. The several positioning seats are gradually reduced from bottom to top and the positioning seats located above are sequentially embedded in the positioning notch of the positioning seat below. Adjacent positioning seats are tightly fitted and the upper surfaces of the several positioning seats are flush.

[0011] The arrangement of several locating seats is used to flexibly match springs of different sizes. Several locating seats have the same shape but different sizes. The outer side of the largest locating seat matches the locating groove and the locating seat is embedded in the locating groove. The outer sides of the remaining locating seats all match the locating notches on the locating seat that is one size larger than it. Thus, several locating seats are embedded in the locating notches of the locating seat below from small to large in sequence from top to bottom. No matter how many locating seats are located in the locating groove, the upper surface of the locating seat and the upper surface of the test bench are always kept flush, and the locating notch in the locating seat at the top is used to locate the spring to be tested. When in use, according to the size of the spring to be tested, remove the positioning seat with a positioning notch that is too small, so that the positioning seat with a positioning notch diameter slightly larger than the spring diameter is located at the top of the positioning groove, and then place the lower part of the spring to be tested into the positioning notch of the positioning seat. On the one hand, the spring positioning is more accurate, so that the spring is subjected to more uniform force when the pushing assembly squeezes the spring, and it is not easy to tilt and deform. On the other hand, the positioning notch plays a certain limiting role on the lower part of the spring, so that the spring is not easy to fly out of the test bench from the side, ensuring the smooth progress of the test and the accuracy of the test results, while avoiding endangering personnel safety.

[0012] In the above-mentioned spring production testing equipment, the lifting assembly includes a driving mechanism and two symmetrically arranged lifting units, the driving mechanism is connected in the base, and the two lifting units are respectively arranged at two C-shaped recesses, the lifting unit includes a screw rod, a guide rod and a slider, the screw rod is vertically arranged at the C-shaped recess and the lower end of the screw rod is connected to the driving mechanism, the number of the guide rods is two, the two guide rods are symmetrically arranged on both sides of the screw rod and the guide rod and the screw rod are parallel to each other, the screw rod and the guide rod are both passed through the slider, the screw rod and the slider are threadedly connected, and the guide rod and the slider are slidingly connected.

[0013] When the lifting assembly is working, the driving mechanism drives the screw to rotate. The slider is threadedly connected to the screw and is also slidably connected to the guide rod. The guide rod is fixed, and the slider converts the rotational force of the screw into an upward or downward linear translation. There are two lifting units symmetrically arranged and driven by the same driving mechanism. The two lifting units can perform lifting movements synchronously. The two sliders are connected to the pushing assembly, thereby driving the pushing assembly to move upward or downward, and the operation stability is high.

[0014] In the above-mentioned spring production testing equipment, the driving mechanism includes a worm gear, a worm and a motor. The base has a cavity inside, and the worm gear and worm are arranged in the base cavity. There are two worm gears and two worm gears. The lower ends of the two screws are respectively passed through the two worm gears and the screw gears are fixedly connected. The two worm gears are respectively meshed with the two worm gears. The motor is fixedly connected to the end of one end of the base, and the two worm gears are connected in series through a connecting shaft to the motor.

[0015] The motor is used to drive the worm to rotate, and the worm is used to drive the worm wheel to rotate, thereby driving the lead screw to rotate. There are two worm wheels and two worms, and the two worm wheels are located on the same horizontal line. The two worms are respectively engaged with the two worm wheels and the two worms are located on the same axis. The two worms are connected in series and connected to the motor through a connecting shaft. The motor can drive the two worms to rotate simultaneously and in the same direction, thereby driving the two lead screws to rotate synchronously and in the same direction, so as to achieve stable lifting and lowering movement of the pushing assembly.

[0016] In the above-mentioned spring production testing equipment, the pushing assembly includes a connecting plate and a pressure plate. The two ends of the connecting plate are respectively fixedly connected to the inner sides of the two sliders, and the pressure plate is fixedly connected to the lower part of the connecting plate and the pressure plate is directly opposite to the positioning assembly up and down.

[0017] The connecting plate is used to connect the two sliders. After the motor is running, the two sliders can move up or down synchronously, driving the connecting plate to move up or down. When in use, after the spring to be tested is placed on the positioning assembly, the connecting plate is controlled to move downward. The pressure plate located under the connecting plate gradually approaches the spring placed on the positioning assembly. After the pressure plate contacts the spring, it continues to squeeze the spring downward to detect the compressive force of the spring. When the length of the spring to be tested is longer, the connecting plate can be controlled to move upward, so that there is enough space between the pressure plate and the positioning assembly to place the spring, which is convenient to use.

[0018] In the above-mentioned testing equipment for spring production, the connecting plate and the slider, and the pressure plate and the connecting plate are fixedly connected by welding.

[0019] The connecting block, slider and pressure plate are all made of metal materials. Welding is used to make the connection between the connecting block and the slider, and between the pressure plate and the connecting plate more stable, so that the spring can be stably squeezed to detect the compressive force of the spring.

[0020] Compared with the existing technology, this spring production testing equipment has a compact structure and stable connection, ensuring the operational stability of the entire equipment. The lifting assembly is driven by the same motor, so that the two sliders can move up and down synchronously, which makes the up and down movement of the pushing assembly smoother and the force on the spring more even. At the same time, several positioning seats are detachably connected to the positioning groove, and the appropriate positioning notch size can be flexibly selected according to the size of the spring to be tested. The spring is placed in the positioning notch, which further improves the stability of the test. The spring is not easy to deform or fly out of the test bench, and the detection accuracy is higher and the safety is higher. BRIEF DESCRIPTION OF THE DRAWINGS
