Description

Technical Field

[0001] The utility model belongs to the technical field of spring processing equipment, in particular to a micro spring integral vibration grinding and polishing machine. 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 shapes, there are mainly coil springs, scroll springs, leaf springs and special-shaped springs. Springs need to be ground and polished during production and processing. At this time, grinding and polishing equipment is needed to grind and polish the springs.

[0003] After searching, the patent announcement number CN213532137 U discloses a fully automatic vibration polishing device, which places the pebbles to be polished in a polishing bowl filled with sand, and the vibration motor generates vibrations and vibrates the polishing bowl through the connecting frame. The sand in the polishing bowl performs friction polishing on the pebbles to be polished during the vibration process. The friction polishing of the pebbles to be polished will produce a large amount of fine dust. When the dust needs to be removed, the load-bearing plate is pulled out of the load-bearing cavity, and the vibration motor generates vibrations and vibrates the polishing bowl through the connecting frame, so that the dust in the sand is deposited at the bottom of the polishing bowl with the vibration and enters the load-bearing cavity through the filter hole, enters the diversion cavity from the load-bearing cavity and flows into the concentration cavity along the inclined slide, and is finally discharged through the collection port. The above-mentioned fully automatic vibration polishing equipment can effectively remove the fine dust generated during the polishing process, ensuring continuous and efficient polishing of the pebbles to be polished.

[0004] When the existing spring vibration grinding and polishing equipment is used to grind and polish a micro spring, the micro spring will sink to the bottom of the grinding sand due to its own weight during the grinding and polishing process, resulting in poor grinding and polishing effect of the micro spring, and the separation efficiency between the micro spring and the grinding sand is not good. For this reason, we propose a micro spring integral vibration grinding and polishing machine to solve the existing problems. Utility Model Content

[0016] 1. The utility model is provided with a series of coordinated structures.

When the micro-spring needs to be separated from the grinding sand after the grinding and polishing of the micro-spring is completed, the staff starts the electric push rod, and the extension of the electric push rod will drive one end of the baffle to rotate. After the baffle rotates to a certain inclination angle, the grinding sand and the micro-spring will slide into the screening trough body due to their own gravity factors, and the up and down vibration of the shell in the Y-axis direction will drive the screening trough body to vibrate up and down in the Y-axis direction. When the screening trough body vibrates up and down in the Y-axis direction, the micro-spring and grinding sand will be screened, and the screened grinding sand will fall into the grinding sand collecting trough body, so that the utility model facilitates the staff to separate the micro-spring and grinding sand, improves the separation efficiency between the micro-spring and the grinding sand, and has strong practicality.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 6The utility model of the micro spring integral vibration grinding and polishing machine mainly comprises a shell 1: baffles 3 are installed on both sides of the upper part of the shell 1, and connecting shafts 11 are installed on one side of the front and rear end walls of the baffle 3, and the other end of the connecting shaft 11 is installed in the sealed bearing on the end wall of the shell 1, and the front and rear ends of one side of the lower surface of the baffle 3 are installed with a first connecting block 13, and the first connecting block 13 is movably connected with the second connecting block 14 through a movable pin shaft, and the second connecting block 14 is installed on one end of an electric push rod 15, and the other end of the electric push rod 15 is installed with a fourth connecting block 24, and the fourth connecting block 24 is movably connected with the third connecting block 16 through a movable pin shaft, and the third connecting block 16 is installed below the inner walls of both sides of the shell 1, and the seal on the center position of the surface of the baffle 3 is fixed. A rotating shaft 12 is installed in the sealed bearing, one end of the rotating shaft 12 is connected to the reduction motor 22 through a coupling, a spiral blade 2 is installed on the outer wall of the other end of the rotating shaft 12, a screening trough 18 and a grinding sand collecting trough 20 are arranged below the baffle 3, and the grinding sand collecting trough 20 is located below the screening trough 18, vibration plates 6 are installed above the outer walls of both sides of the shell 1, a first mounting plate 8 is arranged below the vibration plate 6, and limiting columns 28 are installed at the four corners of the upper surface of the first mounting plate 8, the top of the limiting column 28 passes through the through hole 31 on the surface of the vibration plate 6 and is connected to the limiting plate 27, a vibration motor 7 is installed at the center of the upper surface of the vibration plate 6, when the staff polishes the micro spring 30, the staff will grind the grinding sand and the micro spring After all the sand and micro-spring 30 are poured into the shell 1 and all the sand and micro-spring 30 are located above the baffle 3, the staff starts the vibration motor 7 and the reduction motor 22. When the vibration motor 7 is started, it will drive the shell 1 to vibrate up and down in the Y-axis direction. When the shell 1 vibrates up and down in the Y-axis direction, the sand and micro-spring 30 above the baffle 3 will vibrate. The sand and micro-spring 30 will polish the micro-spring 30 during the vibration process. When the reduction motor 22 is started, it will drive the spiral blade 2 on the outer wall of the rotating shaft 12 to rotate.
