Description

Technical Field

[0001] The present invention relates to the technical field of drying equipment, and more specifically, to a drying equipment for producing leaf springs. Background Art

[0002] As a classic elastic element in the automobile suspension system, the automobile leaf spring is widely popular due to its excellent reliability, simple structure, short manufacturing process and low cost. It is composed of several leaf springs of different lengths. In the suspension system, in addition to playing a buffering role, the automobile leaf spring is also responsible for transmitting force and torque, and determining the movement trajectory of the wheel.

[0003] A Chinese patent with the authorization publication number CN208124734U discloses an automatic drying device for manufacturing automobile leaf springs. By arranging a heating resistor wire and a fan in a box body, the leaf springs are dried. By arranging an upper clamping plate and a lower clamping plate in a control block, the clamping of the leaf springs is facilitated. By arranging a first spring and a second spring in a placement groove, the vibration of the upper clamping plate and the lower clamping plate is facilitated. By arranging a vibration motor in the box body, the moisture of the leaf spring is facilitated to fall off due to vibration. This automatic drying device for manufacturing automobile leaf springs first vibrates the leaf springs to remove water, and at the same time, a water bucket is used to collect the moisture.

[0004] Although this automatic drying device for manufacturing automobile leaf springs is convenient for clamping the leaf springs and then vibrating and dehydrating them by setting an upper clamping plate and a lower clamping plate in the control block, there are some problems in actual use. First, the clamping effect is relatively loose, resulting in the risk of the leaf spring falling off during the vibration dehydration process, which not only affects the dehydration effect, but may also cause damage to the equipment. Secondly, the device cannot be adaptively adjusted for leaf springs of different lengths, limiting its scope of application and flexibility. These problems make the device inefficient and unreliable when processing leaf springs of different specifications, and further improvements are needed to improve the fixing effect and adaptability.

[0033] The drying box 1 of the present device is provided with a drying device and a vibration device inside, which can dry and vibrate and dehydrate the leaf spring body 10 in a fixed state. When the leaf spring body 10 needs to be dried, the leaf spring body 10 is first placed on the two groups of sliders 8, and then the telescopic rod 14 is started to extend the telescopic rod 14 carrying the top block 13. The top block 13 is rotatably connected to the support member 11 on the slider 8 through the connecting rod 12, so the two groups of sliders 8 will move toward each other, and the limit plates 9 on the sliders 8 will move toward each other, so that the leaf spring body 10 is clamped and limited.

[0034] The fixing mechanism 1 includes a rotating shaft 16 rotatably connected inside the support frame 6, a motor 15 is fixedly installed on the rear end surface of the support frame 6, the output shaft of the motor 15 extends to the inside of the support frame 6 and is fixedly connected to the rotating shaft 16, a special-shaped shaft 17 is fixedly installed on the outer surface of the rotating shaft 16, a special-shaped sleeve 18 is rotatably connected to the lower end of the support member 11, the special-shaped sleeve 18 is sleeved on the outer surface of the special-shaped shaft 17, and the special-shaped sleeve 18 is slidably connected to the special-shaped shaft 17, a worm 19 is fixedly installed on the outer surface of the special-shaped sleeve 18, a notch 20 is opened inside the support member 11, a connecting member 21 is fixedly installed inside the notch 20, a threaded rod 22 is rotatably connected to the upper end of the connecting member 21, a worm wheel 23 is fixedly installed on the outer surface of the threaded rod 22, and the worm wheel 23 and the worm 19 are meshed with each other. A slide rail 24 is fixedly installed on the right side of the upper end surface of the connecting member 21, and a threaded sleeve 25 is spirally connected to the upper end of the threaded rod 22, and the threaded sleeve 25 is slidably connected to the slide rail 24. A connecting member 26 is fixedly installed on the upper end of the connecting member 26, and a fixed column 1 27 is fixedly installed on the upper end of the connecting member 26. The end of the fixed column 1 27 is rotatably connected to a rotating block 28, and a sleeve 29 is fixedly installed on the upper end surface of the rotating block 28. The upper end of the sleeve 29 is slidably connected to a fixed column 2 32, and a cross bar 31 is fixedly installed on the upper end surface of the slider 8. Fixed columns 1 27 are fixedly installed on both ends of the cross bar 31. A deflection rod 33 is rotatably connected to the outer surface of the fixed column 27, and the deflection rod 33 is fixedly connected to the transmission column 30, and a clamping rod 34 is fixedly installed on the upper end of the deflection rod 33.

[0035] Then, the motor 15 is started, so that the output shaft of the motor 15 drives the rotating shaft 16 to rotate, and the rotating shaft 16 drives the shaped sleeve 18 to rotate through the shaped shaft 17. The worm 19 on the shaped sleeve 18 rotates synchronously, and the worm wheels 23 on the two sets of threaded rods 22 are meshed with the worm 19, so the threaded rods 22 rotate synchronously, and the threaded sleeve 25 connected to the upper end of the threaded rod 22 by spiral transmission drives the second connecting piece 26 to rise, and the rotating block 28 is rotatably connected to the fixed column 1 27 on the second connecting piece 26, so the rotating block 28 rises synchronously, and the rotating block 28 is further connected to the fixed column 1 27 on the second connecting piece 26. 9 and the transmission column 30 are transmission-connected with the deflection rod 33 on the fixed column 2 32, so that the deflection rod 33 is driven to deflect around the fixed column 2 32, so that the clamping rod 34 on the other end of the deflection rod 33 is displaced toward the leaf spring body 10, and the two sets of clamping rods 34 are synchronously displaced toward the leaf spring body 10 to clamp and fix the leaf spring body 10, wherein the sleeve 29 is slidingly connected with the transmission column 30, and the conflict between the deflection movement of the deflection rod 33 and the upward movement of the connecting piece 26 can be offset by the sliding of the transmission column 30 inside the sleeve 29, thereby ensuring the normal operation of the equipment.

[0036] The fixing mechanism is provided with two sets correspondingly and symmetrically, and both sets of worm wheels 23 are meshed with the worm 19 .

[0037] The second fixing mechanism includes a shell 36 fixedly installed on the left end surface of the interior of the drying box 1, a piston plate 35 is slidably connected inside the shell 36, one end of the telescopic rod 14 is fixedly connected to the piston plate 35, an inner cavity 38 is opened inside the slider 8, a piston plate 2 39 is slidably connected inside the inner cavity 38, a connecting pipe 37 is provided between the inner cavity 38 and the shell 36, a bottom plate 40 is provided on the upper side of the slider 8, a connecting shaft 41 is fixedly installed on the lower end of the bottom plate 40, one end of the connecting shaft 41 extends to the inside of the inner cavity 38, and is fixedly connected to the piston plate 2 39.

[0038] Secondly, when the telescopic rod 14 is extended, the piston plate 1 35 will be synchronously driven to move inside the casing 36, squeezing the gas inside the casing 36, so that the gas inside the casing 36 enters the inner cavity 38 through the connecting pipe 37, thereby causing the piston plate 2 39 slidably connected inside the inner cavity 38 to rise. The piston plate 2 39 is fixedly connected to the bottom plate 40 through the connecting shaft 41, so the bottom plate 40 will rise synchronously and fit tightly against the lower end surface of the leaf spring body 10, and cooperate with the limiting mechanism and the fixing mechanism 1 to firmly fix the leaf spring body 10, and then the drying equipment and the vibration equipment can be started to dry and vibrate the leaf spring body 10 for dehydration.

[0039] The clamping effect of the existing equipment on the leaf spring body 10 is relatively loose, resulting in the risk of the leaf spring body 10 falling off during the vibration dehydration process, which not only affects the dehydration effect, but also may cause damage to the equipment. Secondly, the device cannot be adaptively adjusted for leaf springs of different lengths, limiting its scope of application and flexibility. These problems make the equipment appear to be inefficient and unreliable when processing leaf springs of different specifications, and further improvements are needed to improve the fixing effect and adaptability. Therefore, this solution sets a limit mechanism and uses a telescopic rod 14 to make the two sets of limit plates 9 move toward each other, thereby fixing the leaf spring body 10. It can not only effectively fix leaf springs of different lengths, but also can be adaptively adjusted for leaf springs of different specifications, increasing the flexibility and convenience of the equipment. The use of the telescopic rod 14 allows the limit plate 9 to be accurately adjusted according to the actual length of the leaf spring, ensuring that the leaf spring remains stable during processing or assembly. In addition, the introduction of the limit mechanism simplifies the operation process, reduces the need for manual intervention, and improves production efficiency.

[0040] Instructions for use: The drying box 1 of the device is provided with a drying device and a vibration device inside, which can dry and vibrate and dehydrate the leaf spring body 10 in a fixed state. When the leaf spring body 10 needs to be dried, the leaf spring body 10 is first placed on the two sets of sliders 8, and then the telescopic rod 14 is started to extend the telescopic rod 14 carrying the top block 13. The top block 13 is rotatably connected to the support member 11 on the slider 8 through the connecting rod 12, so the two sets of sliders 8 will move toward each other, and the limit plates 9 on the sliders 8 will move toward each other, so as to clamp and limit the leaf spring body 10;

[0041] Then, the motor 15 is started, so that the output shaft of the motor 15 drives the rotating shaft 16 to rotate, and the rotating shaft 16 drives the special-shaped sleeve 18 to rotate through the special-shaped shaft 17. The worm 19 on the special-shaped sleeve 18 rotates synchronously, and the worm wheels 23 on the two groups of threaded rods 22 are meshed with the worm 19, so the threaded rod 22 rotates synchronously, and the threaded sleeve 25 connected by the spiral transmission at the upper end of the threaded rod 22 drives the connecting piece 26 to rise, and the rotating block 28 is rotationally connected with the fixed column 1 27 on the connecting piece 26, so the rotating block 28 rises synchronously, and the rotating block 28 is transmission-connected with the deflection rod 33 on the fixed column 2 32 through the sleeve 29 and the transmission column 30, so that the deflection rod 33 is driven to deflect around the fixed column 2 32, so that the clamping rod 34 on the other end of the deflection rod 33 moves toward the leaf spring body 10, and the two groups of clamping rods 34 move toward the leaf spring body 10 synchronously to clamp and fix the leaf spring body 10;

[0042] Secondly, when the telescopic rod 14 is extended, the piston plate 1 35 will be synchronously driven to move inside the casing 36, squeezing the gas inside the casing 36, so that the gas inside the casing 36 enters the inner cavity 38 through the connecting pipe 37, thereby causing the piston plate 2 39 slidably connected inside the inner cavity 38 to rise. The piston plate 2 39 is fixedly connected to the bottom plate 40 through the connecting shaft 41, so the bottom plate 40 will rise synchronously and fit tightly against the lower end surface of the leaf spring body 10, and cooperate with the limiting mechanism and the fixing mechanism 1 to firmly fix the leaf spring body 10, and then the drying equipment and the vibration equipment can be started to dry and vibrate the leaf spring body 10 for dehydration.

[0043] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
