Description

Technical Field

[0001] This invention relates to the field of screw grinding, and more specifically to a positioning grinding device for screw production. Background Technology

[0002] The main goal of screw polishing is to remove surface dirt, improve surface finish, and enhance the screw's corrosion resistance and durability. When screw products are shipped in batches, traditional polishing methods such as sandpaper, polishing wheels, and wire brushes are inefficient and slow to deliver, making it difficult to meet customer customization needs and actual production requirements.

[0003] In the process of grinding and cleaning existing screws or bolts, non-standard customization often uses a vibratory feeder and a rotary station to feed a single screw into the grinding station for grinding, which has low processing efficiency.

[0004] A polishing machine (publication number: CN111015486B) is currently available, and more particularly relates to a screw cap polishing machine. The technical problem of this invention is how to provide a screw cap polishing machine that can automatically polish screw caps, achieving mechanical replacement of manual labor. A screw cap polishing machine includes a frame, a first bearing, a second bearing, a third bearing, a first slide rod, a first slider, a second slide rod, a second slider, a U-shaped rack, a servo motor, etc.; the first slide rod and the second slide rod are respectively installed on the upper and lower sides of the U-shaped platform of the frame; the first slider on the first slide rod is connected to the lower side of the U-shaped rack, and the second slider on the second slide rod is connected to the upper side of the U-shaped rack; the servo motor is mounted on the U-shaped platform of the frame. This invention achieves the function of automatically polishing screw caps through mechanical operation; the polishing operation can be continuous, the polished cap surface is smooth, and the operator only needs to feed material onto the tray.

[0005] In the aforementioned prior art, during the polishing process, a pushing mechanism and a clamping mechanism are required to work together to achieve the desired result. The number of screws processed at one time is limited, and the processing efficiency remains low.

[0006] The inventor proposes a positioning and grinding device for screw production. By setting a stepped inclined surface and a limiting inclined plate adapted to the shape of the screw, the device works in conjunction with a vibrating feeder. The vibrating feeder pushes the screws one by one to the grinding station of the misalignment frame for grinding by the end grinding wheel and the middle grinding wheel. Its structural design is simple. In the later use, users only need to adjust the belt tension in a timely manner and maintain the telescopic cylinder, which is convenient for users.

Example

[0025] Reference Figure 1-7 A positioning and grinding device for screw production includes the following structure: The platform 1 has a stepped inclined surface 11 for supporting screws fixed in the middle of the right side.

[0026] Mounting base 3, with a reset spring 31 detachably snapped onto the front and rear ends of the left side of the mounting base 3. The left end of the reset spring 31 is fixed with a limiting inclined plate 32, with the left sides of the two limiting inclined plates 32 facing the stepped inclined surface 11.

[0027] The misalignment frame 4 has a pair of movable shafts 5 at its front, middle and rear. The top and bottom of the shafts 5 at the front and rear ends of the misalignment frame 4 are movably connected to end grinding wheels 51, and the middle shaft 5 in the middle of the misalignment frame 4 is movably connected to a middle grinding wheel 52.

[0028] In this embodiment, the top right side of the platform 1 is detachably connected to an isolation plate 12 by bolts. The bottom surface of the isolation plate 12 covers the stepped slope 11 when viewed from above. An extended receiving end is fixed at the front end of the platform 1. A baffle 13 is detachably connected to the front end of the extended receiving end by bolts. Sliding sleeves 14 are fixed at both the front and rear ends of the top of the platform 1.

[0029] The isolation plate 12 is designed to prevent the debris generated during the grinding of screws by the end grinding wheel 51 and the middle grinding wheel 52 from splashing onto the top of the stand 1, and also to prevent the screws from jumping out between the stepped inclined surface 11 and the limiting inclined plate 32.

[0030] In this embodiment, telescopic cylinders 2 are fixedly installed at both the front and rear ends of the platform 1. The left output ends of the two telescopic cylinders 2 are fixedly connected to the front and rear ends of the truss 21, respectively. Slide rods 22 are fixedly installed at both the front and rear ends of the top of the truss 21. The outer sides of the two slide rods 22 are movably connected to the middle of the two sliding sleeves 14, respectively. The right ends of the two slide rods 22 are fixedly installed with docking seats 23. The bottom of the docking seats 23 is fixedly connected to the front and rear sides of the top of the mounting base 3.

[0031] Telescopic cylinder 2 adjusts the working position of truss 21 on the left side of platform 1, slide rod 22 slides in the middle of sliding sleeve 14, truss 21, slide rod 22 and docking seat 23 cooperate to adjust the working position of mounting seat 3 on the right side of platform 1, adjust the working distance between limiting inclined plate 32 and stepped inclined surface 11, position the guide path of screws, adapt to the grinding and processing requirements of screws of different specifications, and the screw feeding of this equipment can be used in conjunction with vibrating feeder.

[0032] In this embodiment, grinding stations 41 are fixed at the front, middle and rear of the misalignment frame 4. The front view projections of the three grinding stations 41 have overlapping surfaces. The front and rear ends of the misalignment frame 4 are detachably snapped into the left front and rear ends of the mounting base 3.

[0033] The three grinding stations 41 have an overlapping surface design. The end grinding wheel 51 and the middle grinding wheel 52 are used to grind the screws, avoiding any omissions on the outside of the screws.

[0034] As the mounting base 3 moves to the right side of the platform 1, the misalignment frame 4 moves along with the mounting base 3 to complete the adjustment of the working distance between the end grinding wheel 51 and the middle grinding wheel 52 and the outer screw of the stepped inclined surface 11.

[0035] In this embodiment, a drive motor 6 is fixedly installed at the front right side of the misalignment frame 4, and a drive pulley 61 is fixedly installed at the top output end of the drive motor 6. Two guide pulleys 7 are symmetrically and movably connected on the left side of the misalignment frame 4 about the drive motor 6. The outer side of the drive pulley 61 is connected to the outer side of the guide pulley 7 through a belt.

[0036] The drive motor 6 drives the guide pulley 7, tension pulley 92 and grinding pulley 53 to rotate through the drive pulley 61, thereby completing the driving process of the end grinding wheel 51 and the middle grinding wheel 52. Together with the limiting inclined plate 32 and the stepped inclined surface 11, the screw is positioned and guided, thus realizing the positioning and grinding process of the screw.

[0037] In this embodiment, guide seats 8 are welded to the front, middle and rear right sides of the misalignment frame 4. An adjusting bolt 81 is movably sleeved on the rear end of the guide seat 8. A slide 9 is movably connected to the middle part of the guide seat 8. The rear end of the slide 9 is threadedly connected to the outer side of the adjusting bolt 81. An auxiliary shaft 91 is fixedly provided in the middle part of the slide 9. A tensioning pulley 92 is movably connected to the top of the auxiliary shaft 91. The outer side of the tensioning pulley 92 is connected to the outer side of the drive pulley 61 through belt drive.

[0038] The guide seat 8 and the adjusting bolt 81 cooperate to complete the adjustment of the working position of the slide 9 outside the guide seat 8, the adjustment of the working position of the tensioning pulley 92, and the adjustment of the belt tension outside the drive pulley 61, guide pulley 7, tensioning pulley 92 and grinding pulley 53.

[0039] In this embodiment, a grinding pulley 53 is fixedly provided on the top of the shaft 5, and the outer side of the grinding pulley 53 is connected to the outer side of the drive pulley 61 via a belt.

[0040] In this embodiment, the thickness of the central grinding wheel 52 is the same as the superimposed thickness of the two end grinding wheels 51 arranged above and below. The top and bottom of the central grinding wheel 52 extend to the top and bottom of the central inner wall of the misalignment frame 4, respectively.

[0041] The dimensions of the end grinding wheel 51 and the middle grinding wheel 52 are set to avoid the end grinding wheel 51 and the middle grinding wheel 52 being too small, which would cause the screw to miss the grinding area on the stepped slope 11.

[0042] In this embodiment: Telescopic cylinder 2 adjusts the working position of truss 21 on the left side of platform 1. Slide rod 22 slides in the middle of sliding sleeve 14. Truss 21, slide rod 22 and docking seat 23 cooperate to adjust the working position of mounting seat 3 on the right side of platform 1. Adjust the working distance between limiting inclined plate 32 and stepped inclined surface 11 to position the screw guide path. Drive motor 6 drives guide belt pulley 7, tension belt pulley 92 and grinding belt pulley 53 through drive pulley 61 to drive end grinding wheel 51 and middle grinding wheel 52. With the help of limiting inclined plate 32 and stepped inclined surface 11, the screw is positioned and guided to achieve the positioning and grinding of the screw.

[0043] The three grinding stations 41 have overlapping surfaces, and the size settings of the end grinding wheel 51 and the middle grinding wheel 52 are designed to avoid the end grinding wheel 51 and the middle grinding wheel 52 being too small, which would cause the screw to be missed in the grinding area on the stepped slope 11.

[0044] This equipment needs to be used in conjunction with a vibrating feeder to complete the screw feeding process. Alternatively, depending on the amount of processing work, manual screw feeding can be performed at the extended receiving end. The length of the equipment can be increased according to the user's processing needs. At the same time, according to the grinding requirements, the end grinding wheel 51 and the middle grinding wheel 52 can be replaced with polishing wheels for operation. This makes it convenient for the equipment to be modified and deployed according to the user's actual needs. The simplified screw positioning and guiding mechanism of the stepped inclined surface 11 and the limiting inclined plate 32 is reasonably designed and easy to use.

[0045] The above-described embodiments are merely illustrative of certain implementations of the present invention, and are described in a relatively specific and detailed manner. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
