Description

Technical Field

[0001] The invention relates to the field of wrench jaw grinding, in particular to a wrench jaw processing device. Background Art

[0002] The wrench is a common tool. The wrench is produced by heating the steel billet to make it have good plasticity, and then placing the steel billet in a mold for extrusion molding. Since there is a burr groove in the mold, the excess steel will flow into the burr groove and form. After forming, the burr is cut off to complete the initial forging operation.

[0003] After the wrench has gone through the burr removal process, there is an obvious convex edge on the center surface of the wrench, which is not only distributed on the outer surface of the wrench, but also on the inner surface of the jaws. The cooled wrench needs to be manually polished, and manual polishing can only use a sander to grind the convex edges distributed on the outer surface of the wrench flat, but it is impossible to grind the convex edges on the inner surface of the jaws flat. If the convex edges inside the jaws cannot be effectively removed, it will affect the accuracy of the jaw width. At the same time, due to the existence of the convex edge, when the nut is clamped with the wrench, the horizontal surface of the nut side wall cannot fit with the inner plane of the jaws, that is, the nut is easy to shake and slide sideways during the rotation of the wrench.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1-Figure 7 and Fig.12 , a processing device for a wrench jaw in the figure comprises: an assembly housing 1 and a motor 2 fixedly assembled inside the assembly housing 1, a transmission shaft 3 is mounted on a rotating frame on both the left and right side walls of the assembly housing 1, and a first synchronous toothed belt is assembled between the output end of the motor 2 and one end of the two transmission shafts 3 through a first synchronous gear transmission, two assembly plates 7 are mounted on a fixed frame on one side wall of the assembly housing 1, and a rotating shaft 8 is rotatably assembled at the ends of the two assembly plates 7, and a grinding block 9 for grinding the inner wall of the wrench jaw is fixedly mounted on both ends of the rotating shaft 8, and a second synchronous toothed belt is assembled between the rotating shaft 8 and one of the transmission shafts 3 through a second synchronous gear transmission;

[0034] It also includes: an axial floating unit, which is used to evenly grind the convex edge of the inner wall of the wrench jaw, and the axial floating unit is arranged at the bottom of the assembly housing 1;

[0035] The spark extraction unit is used for extracting sparks and smoke generated during grinding, and the spark extraction unit is arranged outside the assembly shell 1.

[0036] The end face of the grinding block 9 away from the mounting plate 7 is in the same horizontal plane as the inner wall of the wrench jaws. The two parallel faces of the inner wall of the wrench jaws are butted against each other via a connecting surface. The side contour of the grinding block 9 is consistent with the contour of the connecting surface of the inner wall of the wrench jaws.

[0037] The axial floating unit includes a base frame 10 axially slidably mounted on the bottom of the assembly shell 1, and a displacement shaft 6 is fixedly mounted on one end face of the base frame 10 away from the assembly plate 7. The displacement shaft 6 is driven to move by an electric push rod or a cylinder. At least two positioning shafts 11 are fixedly mounted on the bottom of the assembly shell 1, and the positioning shafts 11 slide and penetrate the base frame 10. A tension spring 12 is movably mounted on the outside of each positioning shaft 11, and the two ends of the tension spring 12 are fixedly docked with the assembly shell 1 and the base frame 10 respectively. A pushing component is arranged between each transmission shaft 3 and the extended edge of the base frame 10, wherein the displacement shaft 6 moves toward or away from the jaws of the wrench with the base frame 10 and the structure thereon under the action of the electric push rod or the cylinder.

[0038] The pushing component includes a worm sleeve 4 fixedly mounted on the outer surface of each transmission shaft 3, the outer part of the worm sleeve 4 is meshed with a worm wheel 5, and the worm wheel 5 is located between the worm sleeve 4 and the base frame 10, and the center of the worm wheel 5 is fixedly mounted with a positioning column rotatably mounted on the side wall of the assembly shell 1, and the outer surface of the positioning column is also fixedly mounted with a cam 13, and the outer surface of the cam 13 is slidably fitted with the upper end surface of the base frame 10. When the motor 2 drives the transmission shaft 3 to rotate, the cam 13 can be driven to rotate through the meshing of the worm sleeve 4 and the worm wheel 5, and the cam 13 can push the assembly shell 1 upward each time it rotates one circle, that is, the assembly shell 1 moves upward slightly on the basis of the base frame 10.

[0039] The working principle of effectively grinding and leveling the convex edge inside the wrench jaws:

[0040] The staff can use an electric push rod or a cylinder to move the displacement shaft 6 to ensure that the grinding block 9 can move toward the inside of the wrench jaws. When the wrench is fixed, the motor 2 is started, and the motor 2 drives the transmission shaft 3 to rotate at a high speed, and can also drive the grinding block 9 to rotate quickly. During the rotation process, the base frame 10 and the assembly shell 1 are moved toward the wrench jaws through the displacement shaft 6, and the grinding block 9 gradually enters the inside of the wrench jaws under the state of high-speed rotation. During the embedding process, the convex edge of the inner wall of the jaws can be polished and leveled;

[0041] During the process of the motor 2 driving the transmission shaft 3 to rotate, the cam 13 can also be rotated through the assembly of the worm sleeve 4 and the worm wheel 5. When the two cams 13 rotate synchronously for one circle, the assembly shell 1 can be lifted up by one end. Under the action of the tension spring 12, the motor 2 can cause the assembly shell 1 to float up and down inside the base frame 10 during the driving process. At this time, the grinding block 9 will also float up and down with the assembly shell 1, so that the grinding block 9 can grind the convex edge in the wrench jaws while floating up and down, which can further ensure the effectiveness and flatness of the grinding.

[0042] In this solution, the wrench jaws can be polished in batches. The wrenches that need to be polished can be stacked and slowly moved vertically downward or upward, so that the inner walls of the wrench jaws can be polished in batches. This solution is suitable for production workshops.

[0043] Example 2: Please refer to Figure 8-Figure 11 This embodiment is a further explanation of embodiment 1. The spark extraction unit includes a return pipe 14 fixedly assembled on the outer surface of the assembly shell 1. The return pipe 14 is in a notched ring shape, and the return pipe 14 surrounds the assembly shell 1 and the base frame 10 on the inner side. The notches of the return pipe 14 are an upper port portion and a lower port portion. The grinding block 9 is placed between the upper port portion and the lower port portion. The upper port portion and the lower port portion are fixedly provided with a flaring portion 21. A suction component and a filtering component are arranged inside the return pipe 14. During the operation of the suction component inside the return pipe 14, the smoke and sparks generated by grinding can be sucked into the interior of the return pipe 14, and they will not splash or diffuse in the working space at will.

[0044] The suction component includes a driving shaft 15 whose rotating frame is mounted inside the return pipe 14. The driving shaft 15 is vertically distributed with the transmission shaft 3, and the driving shaft 15 is located on the side of the return pipe 14 away from the notch. The outer surface of the driving shaft 15 is fixedly sleeved with a blade wheel 17. The rotating frame at one end surface of the assembly shell 1 close to the driving shaft 15 is equipped with a connecting column, and a third synchronous toothed belt is assembled between the connecting column and the driving shaft 15 through a third synchronous gear. A bevel gear 16 is fixedly sleeved between one end of the connecting column and the outer surface of the transmission shaft 3, and the two bevel gears 16 are meshed with each other. The transmission shaft 3 can rotate at high speed with the driving shaft 15 and the blade wheel 17 through two meshing bevel gears 16.

[0045] The filtering component includes an air filter element 18 and a filter plate 19 fixedly installed inside the return pipe 14. The air filter element 18 and the filter plate 19 are distributed up and down. The filter plate 19 is inclined, and the upper edge of the filter plate 19 is inclined toward the flared portion 21. The lower end of the return pipe 14 is equipped with a detachable waste box 20, and the waste box 20 is located directly below the filter plate 19. The air filter element 18 can filter pungent smoke, and the filter plate 19 can isolate metal debris that cause sparks.

[0046] The direction of the airflow conveyed by the impeller 17 is from bottom to top, that is, the airflow inside the return pipe 14 flows counterclockwise.

[0047] The interior of the reflux pipe 14 is also provided with a slag-removing component for intermittently knocking the filter plate 19, and the slag-removing component includes a knocking block 22 placed on top of the filter plate 19, and a column 23 that slides through the reflux pipe 14 is fixedly installed on the top of the knocking block 22, and the outer surface of one end of the column 23 extending out of the reflux pipe 14 is fixedly covered with a disk 24, and a spring 25 is fixedly assembled between the end of the disk 24 close to the knocking block 22 and the reflux pipe 14, the disk 24 is located between the base frame 10 and the reflux pipe 14, and a toggle piece is also provided between the base frame 10 and the column 23, and the toggle piece triggers the knocking block 22 to knock the filter plate 19, so that metal debris attached to the surface or inside of the filter plate can fall into the inside of the waste box 20.

[0048] The toggle member includes a ratchet plate 30 elastically slidably hoisted at the bottom of the base frame 10, a frame plate 26 is arranged on the side of the disk body 24, and the frame plate 26 is fixedly connected to the reflux pipe 14, the inner rotation of the frame plate 26 is equipped with a connecting shaft 27, and the outer surface of the connecting shaft 27 is respectively fixedly covered with a ratchet 28 and a turntable 32, the ratchet plate 30 and the connecting shaft 27 are vertically distributed, and the ratchet plate 30 is movably engaged with the ratchet 28, when the ratchet 28 moves upward, the ratchet 28 can be engaged and rotated through the action of the ratchet plate 30, and when the ratchet 28 moves downward, the ratchet plate 30 can be elastically pushed away, and the ratchet The plate 30 is elastically slidable laterally at the bottom of the base frame 10, and a limit ratchet block 29 is also meshed and assembled on the top of the ratchet 28. The limit ratchet block 29 is elastically rotated and assembled with the frame plate 26 through a rotating column and a torsion spring. At least one group of teeth 33 is fixedly provided on the outer surface of the turntable 32, and the number of teeth 33 in each group is 3-5. The outer surface of the column 23 is provided with a plurality of tooth grooves 31 meshing with the teeth 33. Each time the reflux pipe 14 moves upward with the assembly shell 1, it can make the ratchet 28 rotate counterclockwise by a small angle, and under the restriction of the limit ratchet block 29, the ratchet 28 cannot rotate.

[0049] In this embodiment: In this scheme, the rotation direction of the grinding block 9 is limited. When the grinding block 9 contacts the convex edge inside the wrench jaws, the sparks generated are splashed downward. Since the transmission shaft 3 can rotate at high speed with the drive shaft 15 and the blade wheel 17 at the same time, the blade wheel 17 can suck the sparks and the smoke generated by grinding through the lower port of the return pipe 14, so that most of the smoke and sparks enter the interior of the return pipe 14, where the smoke can be filtered by the air filter element 18 and then discharged, and the metal debris turned into by the sparks after cooling will be isolated by the filter plate 19 or attached to the filter plate 19, where the airflow inside the return pipe 14 flows counterclockwise. During the flow process, it can also cool the wrench jaws to avoid overheating of the wrench jaws and affecting the normal collection of workers.

[0050] In this solution, since the return pipe 14 can move up and down with the assembly housing 1, and the ratchet plate 30 is limited to the bottom of the base frame 10, when the return pipe 14 moves upward with the frame plate 26, the ratchet 28 can rotate a small angle under the action of the ratchet plate 30 and will not rotate back, that is, the ratchet 28 can intermittently rotate counterclockwise;

[0051] When the turntable 32 follows the ratchet 28 to intermittently rotate counterclockwise, the teeth 33 engage with the tooth grooves 31 to lift the column 23 for a distance and then release it instantly. At this time, the spring 25 in the compressed state can elastically reset the knocking block 22 and knock on the surface of the filter plate 19. When the metal debris attached to the filter plate 19 or inside falls off, it falls into the waste box 20 for collection, thereby ensuring that the filter plate 19 can always effectively isolate the metal debris without affecting the ventilation effect inside the reflux pipe 14.

[0052] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
