Description

Technical Field

[0001] This utility model relates to the technical field of flocked spring processing equipment, specifically to a positioning auxiliary mechanism for flocked spring upper parts. Background Technology

[0002] Flocked springs are spring products with flocked fibers attached to their surface using flocking technology. The flocked spring surface has a certain degree of elasticity and softness, which can absorb some of the impact and vibration, thereby reducing the vibration transmitted to the vehicle interior and improving ride comfort. They are widely used in the automotive industry and other fields, and have functions such as shock absorption, noise reduction, and extended service life.

[0003] Before spraying the flocked springs, a conveyor line is needed to transport the flocked springs. Once the flocked springs are transported to the spraying area, the spraying operation can be carried out on the flocked springs.

[0004] However, because the spring is an elastic floating structure, the existing flocked spring feeding auxiliary positioning mechanism is not stable and accurate enough for feeding and positioning flocked springs on different types of conveyor lines, which reduces the conveying efficiency of the flocked springs on the subsequent conveyor line. Therefore, there is an urgent need for a spring flocking loading and positioning auxiliary mechanism to solve the above problems. Utility Model Content

A driven bevel gear is fixedly provided at the end of the inner end face of each set of transmission screws. Two sets of linear sliders are provided on the upper end face of the guide chuck.

[0007] The positioning device comprises six sets, and the six sets of positioning devices are threadedly connected to the inner end face of the guide groove via the transmission screw. A flocked spring is fixedly engaged on the inner end face of the positioning device, and the positioning device is used to limit and guide the flocked spring.

[0008] A servo motor is fixedly mounted at the top center of the guide chuck, and an active bevel gear is provided at the output end of the servo motor.

[0009] Preferably, the positioning device includes a threaded guide seat for guidance, a stepper motor is provided on the upper end face of the threaded guide seat, and a bidirectional ball screw is provided at the output end of the stepper motor. Two sets of limiting clamps are slidably connected on the upper part of the inner end face of the threaded guide seat, and a ball slide is provided on the lower end face of the limiting clamp. A limiting retaining ring is provided on the top of the limiting clamp, and a positioning guide shaft is provided at the center of the upper end face of the threaded guide seat.

[0010] Preferably, all six sets of driven bevel gears are meshed with the driving bevel gear, which facilitates the subsequent adjustment of the feeding distance of the six positioning devices by the driving bevel gear driving the six sets of transmission screws through the six sets of driven bevel gears, making it convenient to adapt to different types of conveyor lines.

[0011] Preferably, the threaded guide seat is threadedly connected to the inside of the guide groove via the transmission screw. The six sets of threaded guide seats can be threadedly connected to the inside of the guide chuck via the transmission screw, which facilitates the rapid and precise adjustment of the spacing of the six sets of positioning devices, thereby improving the adaptability of the equipment.

[0012] Preferably, the flocked spring and the positioning guide shaft are coaxially slidably engaged, and the limiting retaining ring is fitted and connected to the bottom of the flocked spring. The positioning guide shaft can coaxially position flocked springs of different diameters, and the two sets of limiting retaining rings can also limit the bottom of the flocked spring, thereby improving the stability of guiding the flocked spring.

[0013] Preferably, the limiting clamp is adapted to the bidirectional ball screw through the ball slide and is then threadedly connected inside the threaded guide seat. The threaded connection between the two sets of ball slides and the bidirectional ball screw facilitates the subsequent limiting retaining ring to limit the bottom of the flocked spring. At the same time, the separate limiting method also facilitates the subsequent equipment to adaptively limit flocked springs of different sizes.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting up a positioning device, can effectively improve the accuracy and stability of guiding the flocked springs during feeding and positioning by having the positioning guide shaft coaxial with the flocked spring. At the same time, the two sets of limiting clamps and limiting retaining rings can improve the adaptability of limiting and guiding flocked springs of different diameters. When feeding different types of conveyor lines, the servo motor can synchronously drive six sets of driven bevel gears and transmission screws to rotate through the active bevel gear, so that the six sets of transmission screws can accurately adjust the distance between the six sets of positioning guide shafts and the conveyor line, effectively improving the adaptability and stability of the equipment for auxiliary feeding and positioning of flocked springs.

[0024] The positioning device 2 has six sets, and the six sets of positioning devices 2 are connected to the inner end face of the guide slide 7 by the transmission screw 5. The flocked spring 3 is fixedly clamped on the inner end face of the positioning device 2. The positioning device 2 is used to limit and guide the flocked spring 3.

[0025] The servo motor 6 is fixedly mounted at the top center of the guide chuck 8, and an active bevel gear 1 is provided at the output end of the servo motor 6.

[0026] The positioning device 2 includes a threaded guide seat 24 for guidance. A stepper motor 22 is provided on the upper side of the threaded guide seat 24, and a bidirectional ball screw 23 is provided at the output end of the stepper motor 22. Two sets of limiting clamps 27 are slidably connected on the upper part of the inner end face of the threaded guide seat 24, and a ball slide 25 is provided on the lower end face of the limiting clamp 27. A limiting retaining ring 21 is provided on the top of the limiting clamp 27, and a positioning guide shaft 26 is provided at the center of the upper end face of the threaded guide seat 24.

[0027] All six driven bevel gears 4 are meshed with the driving bevel gear 1, which allows the driving bevel gear 1 to drive the six sets of transmission screws 5 through the six driven bevel gears 4 to adjust the feeding distance of the six positioning devices 2, making it easy to adapt to different types of conveyor lines.

[0028] The threaded guide seat 24 is threadedly connected to the inside of the guide groove 7 via the transmission screw 5. The six sets of threaded guide seats 24 can be threadedly connected to the inside of the guide chuck 8 via the transmission screw 5, which facilitates the rapid and precise adjustment of the spacing of the six sets of positioning devices 2, thereby improving the adaptability of the equipment.

[0029] The flocked spring 3 is coaxially slidably engaged with the positioning guide shaft 26, and the limiting retaining ring 21 is fitted and connected to the bottom of the flocked spring 3. The positioning guide shaft 26 can coaxially position flocked springs 3 of different diameters, and the two sets of limiting retaining rings 21 can also limit the bottom of the flocked spring 3, which improves the stability of guiding the flocked spring 3.

[0030] The limiting fixture 27 is adapted to the bidirectional ball screw 23 via the ball slide 25 and then threadedly connected inside the threaded guide seat 24. The threaded connection between the two sets of ball slides 25 and the bidirectional ball screw 23 facilitates the subsequent limiting retaining ring 21 to limit the bottom of the flocked spring 3. At the same time, the separate limiting method also facilitates the subsequent equipment to adaptively limit flocked springs 3 of different sizes.

[0031] Working Principle: Before use, the operator can position the equipment on the external transfer module and connect the linear slider 9 to the external linear guide rail for easy transfer and positioning of the flocked springs 3. When the flocked springs 3 are being fed and limited, the stepper motor 22 starts. The stepper motor 22 is connected to the ball slide 25 via the bidirectional ball screw 23, thereby driving the two sets of limit clamps 27 to centrifugal displacement, providing sufficient guiding space for the feeding of the flocked springs 3. Subsequently, the external feeding robot arm can synchronously position multiple sets of flocked springs 3 to the coaxial position of the positioning guide shaft 26, and then guide the flocked springs 3 into the interior of the positioning guide shaft 26. After the guiding is completed, the stepper motor 22 can drive the ball slide 25 and the limit clamps 27 to reset via the bidirectional ball screw 23, and the two sets of limit retaining rings 21 can read... The bottom of the flocked spring 3 is limited, and then the external transfer module can drive the flocked spring 3 and the limiting clamp 27 to move to the upper part of the conveyor line. When the flocked spring 3 is unloaded, the positioning guide shaft 26 can be aligned with the positioning shaft of the positioning guide shaft 26 on the conveyor line. Then the stepper motor 22 can drive the two sets of limiting clamps 27 and limiting retaining rings 21 to separate through the bidirectional ball screw 23. At this time, the flocked spring 3 can be aligned and slide down onto the positioning shaft of the conveyor line, which is convenient for subsequent conveying and spraying. If it is necessary to adapt to conveyor lines with different spacing, the operator can start the servo motor 6. The servo motor 6 can drive the active bevel gear 1 to rotate. The active bevel gear 1 can drive the six sets of transmission screws 5 to rotate synchronously through the six sets of driven bevel gears 4, thereby synchronously adjusting the spacing of the six sets of flocked springs 3 aligned with different conveyor lines.
