Description

Technical Field

[0001] The present invention relates to the technical field of automatic polishing machines, and particularly to a full-automatic conveying line polishing machine for hammer production and processing. Background Art

[0002] A hammer is a hand tool that realizes object fixation, shaping or destruction through impact force. Its core structure is a hammer head and a handle. During the forging process of existing hammers, the hammer head needs to be polished. Existing polishing methods are divided into manual and automatic. Manual polishing is that workers hold the hammer head by hand and polish it by rubbing the hammer head against a grinding wheel. Common automatic polishing is to pick up the hammer head by a robotic arm and contact it with the grinding wheel for polishing. Manual polishing has a lower cost but requires skilled workers, and the quality of the produced products fluctuates greatly and the efficiency is low, which is mostly used in small-scale production with low product added value. The products polished by the robotic arm have high quality, but the use and maintenance costs are high, which are mostly used in production with high added value. When these two methods are actually used, one worker or a robotic arm can often only polish one hammer head at a time, and the grinding efficiency is low. When multiple groups need to be polished simultaneously, multiple workers or multiple groups of robotic arms need to be equipped. Moreover, manual grinding requires skilled workers, and robotic arm automatic production requires programming personnel. Both require technical personnel, the production threshold is high, and the replaceability of workers is poor. Summary of the Invention

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1-12, the present invention provides a technical solution: a fully automatic conveyor line polishing machine for hammer production and processing, including a mounting base 1, on which a mounting bracket 2 is fixedly installed, on which two mounting boxes 3 are fixedly installed, on which two first driving wheels 4 are rotatably installed, on which a grinding sand strip 5 is sleeved, on the mounting base 1 a conveyor belt bracket 6 is fixedly installed, on which two second driving wheels 7 are rotatably installed, on which a conveyor belt 8 is sleeved, and on which mounting blocks 9 are fixedly installed in an array;

[0034] A clamping mechanism 10, which includes a first connecting block 1001 and a clamping plate 1006. The first connecting block 1001 is movably arranged on the mounting block 9, and two clamping plates 1006 are movably arranged on one side of the first connecting block 1001;

[0035] A driving mechanism 11, which includes a turntable 1101 and a second large driving gear 1106. The turntable 1101 is movably arranged on the mounting block 9, and the second large driving gear 1106 is installed on one side of the turntable 1101;

[0036] A protection mechanism 12, which includes a connecting plate 1201 and an arc plate 1203. The connecting plate 1201 is arranged on the mounting bracket 2, and the arc plates 1203 are installed on the left and right sides of the connecting plate 1201. This device can automatically polish the side and front of the hammer head, and can achieve uninterrupted automatic polishing with the cooperation of manual loading and unloading. Compared with traditional manual polishing, it greatly improves the polishing efficiency, increases the uniformity of the polishing quality, and saves labor. Compared with the existing method of using a robotic arm to grab the hammer for polishing, it saves the cost of automatic polishing, can polish multiple groups of hammers at the same time, and also improves the polishing efficiency. The structure of the device is simple and the operation is convenient, which is suitable for small-scale hammer production workshops. The clamping mechanism 10 set in the device has the ability to fix the hammer, and there are few loading and unloading steps for the hammer during operation, and the clamping is stable. Figure 1 Taking the front view as the main view, the hammer loading and unloading part of the device is on the right side of the device, the rotation direction of the conveyor belt 8 is clockwise, the rotation directions of the two first driving wheels 4 are opposite to the movement direction of the mounting block 9. There is a motor and a transmission mechanism for driving the rotation of the first driving wheel 4 in the mounting box 3, and there is also a motor for driving the rotation of the second driving wheel 7 fixedly installed on the mounting base 1. The combination of the mounting box 3, the first driving wheel 4 and the grinding sand strip 5 is a commonly used grinding wheel structure in the field of hammer polishing, and the combination of the conveyor belt bracket 6, the second driving wheel 7 and the conveyor belt 8 is a commonly used conveyor belt structure, both of which are existing mature technologies, so the working principle will not be elaborated here.

[0037] Further, the clamping mechanism 10 further includes a second fixing block 1002, a first guiding rod 1003, a first movable block 1004, a guiding hole 1005, a clamping block 1007, a second guiding rod 1008, a second movable block 1009, a return spring 1010, a hinge rod 1011 and a third movable block 1012. The first connecting block 1001 is fixedly installed on the turntable 1101. The second fixing block 1002 is fixedly installed on the first connecting block 1001. Two groups of first guiding rods 1003 are fixedly installed on both sides of the second fixing block 1002. Two groups of first movable blocks 1004 are movably installed on the second fixing block 1002. Two groups of guiding holes 1005 are formed on the two groups of first movable blocks 1004. The first guiding rod 1003 is inserted into the guiding hole 1005. Clamping plates 1006 are fixedly installed on the two groups of first movable blocks 1004. Clamping blocks 1007 are fixedly installed on the upper sides of the two groups of clamping plates 1006. The second guiding rod 1008 is fixedly installed on the second fixing block 1002. The second movable block 1009 is movably sleeved on the second guiding rod 1008. The return spring 1010 is sleeved on the second guiding rod 1008. One side of the return spring 1010 abuts against the second movable block 1009. Hinge rods 1011 are hinged on both sides of the second movable block 1009. One ends of the two groups of hinge rods 1011 are hinged on the opposite sides of the two groups of first movable blocks 1004. The third movable block 1012 is fixedly installed on the lower side of the second movable block 1009. The third movable block 1012 moves under the second fixing block 1002. The schematic diagram of this structure is Figure 5 and Figure 6 , the main function of this structure is that when the third movable block 1012 is extruded and moves, the hinge rod 1011 will gradually unfold, thereby pushing the first movable blocks 1004 to move away from each other at the same time. When the third movable block 1012 is not extruded or limited, it can return to its original position under the action of the return spring 1010 to Figure 4For example, in the general production process of a hammer, the hammer head and the hammer handle are separated and finally assembled together. Therefore, a hammer handle groove is generally provided on the hammer head. Two sets of clamping plates 1006 are inserted into the hammer handle groove. It should be noted that when the third moving block 1012 is not stressed, the second moving block 1009 abuts against one side of the second fixed block 1002 under the action of the elastic force of the return spring 1010, and the hinge rod 1011 is in a retracted state. At this time, the opposite sides of the clamping plates 1006 are in contact, and the engaging block 1007 can pass through the hammer handle groove. When the third moving block 1012 moves under stress, the clamping plates 1006 will move relatively away and fit against the inner wall of the hammer handle groove. At this time, the engaging block 1007 will limit the position of the hammer head. Therefore, the function of the return spring 1010 is to reset, rather than limit the position of the hammer head through its own elastic force. The shape of the outer side of the clamping plate 1006 is adapted to the shape of the inner side of the hammer handle groove, which can make the contact area between the clamping plate 1006 and the hammer handle groove larger and the fixation more secure when fixing. The edge of the engaging block 1007 is rounded, which can squeeze the edge of the hammer handle groove when the clamping plate 1006 expands. Under the guidance of the rounded corner, a downward force can be applied to the hammer head, making the hammer head more stably fixed on the clamping mechanism 10;

[0038] Further, the clamping mechanism 10 further includes moving grooves 1013, third guide rods 1014, limiting springs 1015, fourth moving blocks 1016, first limiting blocks 1017 and first limiting grooves 1018. Two sets of moving grooves 1013 are provided on the lower side of the second fixed block 1002. Third guide rods 1014 are fixedly installed in both sets of moving grooves 1013. Limiting springs 1015 are sleeved on the third guide rods 1014. Fourth moving blocks 1016 are movably sleeved on the third guide rods 1014. One side of the fourth moving block 1016 abuts against the limiting spring 1015. First limiting blocks 1017 are fixedly installed on the lower sides of both sets of fourth moving blocks 1016. First limiting grooves 1018 are provided on the third moving block 1012, and the positions of the first limiting grooves 1018 are opposite to those of the two first limiting blocks 1017. The schematic diagram of this structure is Figure 7 、 Figure 8 and Figure 11, the main function of this structure is to limit the third movable block 1012, so that the clamping plate 1006 remains in an open state, so that the clamping plate 1006 can stably fix the hammer head. In addition to quickly resetting the third movable block 1012 when the first limiting block 1017 is relatively close, the reset spring 1010 can also increase the pressure at the contact area between the first limiting block 1017 and the third movable block 1012 when the first limiting block 1017 abuts against the third movable block 1012, thereby increasing the stability of fixing the hammer head. The ends of the two groups of first limiting blocks 1017 are right-angled triangular blocks, and the right-angled sides are opposite. When the third movable block 1012 contacts the ends of the first limiting blocks 1017, the two groups of first limiting blocks 1017 can be relatively close under the contact of the inclined surfaces at their ends, and then the first limiting blocks 1017 are engaged at the first limiting grooves 1018 under the action of the elastic force of the limiting springs 1015, which increases the convenience and stability of the equipment during use;

[0039] Further, the clamping mechanism 10 further includes a first arc-shaped block 1019, a second arc-shaped block 1020 and a placement block 1021. The first arc-shaped blocks 1019 are fixedly installed on both groups of first limiting blocks 1017, the second arc-shaped block 1020 is fixedly installed on one side of the third movable block 1012, and the placement block 1021 is fixed on the upper side of the first connecting block 1001. The schematic diagram of this structure is Figure 5 and Figure 8 , the provided second arc-shaped block 1020 and the first arc-shaped block 1019 make the pushing of the third movable block 1012 and the relative extrusion of the first limiting blocks 1017 more convenient and comfortable. The shape of the placement block 1021 is adapted to the shape of the rear side of the hammer head, which can quickly position the hammer head. At the same time, it also increases the stability during loading to a certain extent and provides conditions for the subsequent rotation of the hammer head. The thickness of the second arc-shaped block 1020 is adapted to the length of the triangular block at the end of the first limiting block 1017, which can prevent the first limiting block 1017 from poking the user's hand when the third movable block 1012 moves, and increases the comfort of the equipment during use;

[0040] Further, the driving mechanism 11 further includes a rotating shaft 1102, a first small driving gear 1103, a first large driving gear 1104, a second small driving gear 1105, a shielding box 1107, an annular groove 1108 and an annular gear 1109. The center of the turntable 1101 is opposite to the center of the hammer head. A rotating shaft 1102 is fixedly installed at the center position on one side of the turntable 1101. The rotating shaft 1102 is rotatably installed in the mounting block 9. One end of the rotating shaft 1102 is fixedly installed with a first small driving gear 1103. A first large driving gear 1104 is engaged with one side of the first small driving gear 1103. The first large driving gear 1104 is rotatably installed on the mounting block 9. A second small driving gear 1105 is fixedly installed on the first large driving gear 1104. A second large driving gear 1106 is engaged with one side of the second small driving gear 1105. The second large driving gear 1106 is rotatably installed on the mounting block 9. The upper end of the second large driving gear 1106 exceeds the upper end of the mounting block 9. A shielding box 1107 is fixedly installed on one side of the mounting block 9. The first small driving gear 1103, the first large driving gear 1104, the second small driving gear 1105, the second large driving gear 1106 and the shielding box 1107 are all located inside the shielding box 1107. An annular groove 1108 is formed on the transmission belt bracket 6. The second large driving gear 1106 is inserted into the annular groove 1108. An annular gear 1109 is fixedly installed in the annular groove 1108. The second large driving gear 1106 is engaged with the annular gear 1109. The schematic diagram of this structure is Figure 5 , Figure 9 and Figure 12 . When the mounting block 9 moves along with the conveyor belt 8, the turntable 1101 can rotate under the transmission of gears such as the first small driving gear 1103. Since the center of the turntable 1101 is opposite to the center of the hammer head, the round block of the hammer head rotates automatically, providing adjustment for subsequent side grinding and making the front grinding of the hammer head more uniform. The first small driving gear 1103 and the second small driving gear 1105 are the same in size and shape. The first large driving gear 1104 and the second large driving gear 1106 are the same in size and shape. The diameter of the first large driving gear 1104 is larger than that of the first small driving gear 1103. The gear set composed of the first small driving gear 1103 and other gears can make the hammer head rotate quickly, making the grinding effect better and making the force on the clamping mechanism 10 more uniform, reducing the pressure on a single part of the clamping mechanism 10, and thus reducing the possibility of damage to the clamping mechanism 10;

[0041] Further, there are no teeth between the upper right side and the lower right side of the annular gear 1109. The lower end of the first connecting block 1001 is flush with one end of the turntable 1101. The upper side of the first connecting block 1001 does not exceed the center of the turntable 1101. The schematic diagram of this structure is Figure 4 and Figure 12, since the hammer head needs to be loaded and unloaded manually, and the hammer head rotates during the operation of the equipment and cannot be loaded and unloaded, the periodic absence of teeth on the ring gear 1109 can stop the hammer head from rotating, enabling the workers to perform normal loading and unloading. As Figure 4 shown, due to the eccentric arrangement of the clamping mechanism 10, when the second largest driving gear 1106 is not engaged with the ring gear 1109, under the action of gravity, the hammer head is in the Figure 4 position, allowing the workers to carry out the loading and unloading work normally. And when the hammer head is in the Figure 4 position, the tooth positions of the second largest driving gear 1106 are adapted to the tooth positions of the lower ring gear 1109, so that when the mounting block 9 on the right rotates to the lower side and the second largest driving gear 1106 contacts the ring gear 1109, they can quickly engage;

[0042] Furthermore, the two grinding sand strips 5 are opposite to the central positions on the upper and lower sides of the transmission belt bracket 6. The two grinding sand strips 5 are perpendicular. The lower grinding sand strip 5 contacts the side surface of the hammer head round block on the second largest driving gear 1106, and the upper grinding sand strip 5 contacts the front surface of the hammer head round block on the second largest driving gear 1106. The schematic diagram of this structure is Figure 1 and Figure 3 . This structure enables the grinding sand strips 5 to grind the side and front surfaces of the hammer head, thus realizing automatic polishing. The length of the grinding sand strips 5 is less than the length of the transmission belt bracket 6. On the one hand, it is to prevent the sparks splashed during the contact between the grinding sand strips 5 and the hammer head from being too close to the workers. On the other hand, it is to allow the hammer head to be cooled at the arc end of the transmission belt bracket 6 to prevent the hammer head from being too hot and making it difficult to load and unload;

[0043] Furthermore, the protection mechanism 12 further includes an insertion slot 1202, a shielding plate 1204 and a through slot 1205. The connecting plate 1201 is provided with the insertion slot 1202, and the mounting bracket 2 is inserted into the insertion slot 1202. The two arc-shaped plates 1203 are both fixedly installed on the transmission belt bracket 6. The shielding plates 1204 are fixedly installed on the upper and lower sides of the two arc-shaped plates 1203. The through slots 1205 are opened on the shielding plates 1204, and the positions of the through slots 1205 are opposite to the positions of the mounting blocks 9. The schematic diagram of this structure is Figure 1 and Figure 10 . This structure enables the shielding plate 1204 to shield the sparks splashed during grinding and polishing, avoiding harm to the workers caused by the spark splashing. At the same time, since the movement direction of the upper grinding sand strip 5 is opposite to the movement direction of the mounting block 9, the splashing direction of the sparks is opposite to the position of the workers and will be shielded by the shielding plate 1204 at the same time, so the flash of the sparks will not affect the work of the workers;

[0044] Furthermore, the protection mechanism 12 further includes a placement groove 1206, a placement bracket 1207, and a loading box 1208. A placement groove 1206 is formed in the arc-shaped plate 1203 on the right side. The connecting plate 1201 is inclined forward. A placement bracket 1207 is fixedly installed on the mounting base 1. A loading box 1208 is placed on the upper side of the placement bracket 1207. The upper side of the loading box 1208 is in contact with the connecting plate 1201. The schematic diagram of this structure is Figure 1 and Figure 10 , this structure enables workers to insert the polished hammer head into the placement groove 1206 and enter the loading box 1208 under the guidance of the connecting plate 1201, increasing the convenience for workers to disassemble the hammer head;

[0045] Furthermore, the protection mechanism 12 further includes a second limiting groove 1209 and a second limiting block 1210. Four groups of second limiting grooves 1209 are formed in the lower side of the loading box 1208. Four groups of second limiting blocks 1210 are fixedly installed on the placement bracket 1207. The second limiting blocks 1210 are inserted into the second limiting grooves 1209. A handle is fixedly installed on the upper side of the loading box 1208. The upper end of the front side of the loading box 1208 is higher than the upper end of the rear side of the loading box 1208. The upper end of the front side of the loading box 1208 is flush with the front side of the connecting plate 1201. The schematic diagram of this structure is Figure 3 and Figure 10 , this structure enables the loading box 1208 not to cause the hammer head to cross over the loading box 1208 due to the too fast falling speed of the hammer head when receiving the hammer head. The higher front side of the loading box 1208 can prevent the movement of the hammer head. The second limiting blocks 1210 are used for positioning to avoid the hammer head colliding with the inner wall of the loading box 1208 and causing the loading box 1208 to tip over.

[0046] Working principle: When the present invention is in use, the clamping plate 1006 is inserted into the hammer handle groove of the hammer head, so that the engaging block 1007 exceeds the hammer handle groove, and then the third movable block 1012 is pushed. At this time, the second movable block 1009 moves along the second guiding rod 1008 and compresses the return spring 1010. At this time, the hinge rod 1011 gradually unfolds, so that the first movable block 1004 and the clamping plate 1006 move relatively away from each other. The clamping plate 1006 presses against the inner wall of the hammer handle groove, and the engaging block 1007 is engaged with the edge of the hammer handle groove. When the third movable block 1012 moves, the edge of the first limiting groove 1018 contacts the inclined surface at the end of the first limiting block 1017, so that the first limiting block 1017 moves relatively closer. At this time, the fourth movable block 1016 moves along the third guiding rod 1014 in the movable groove 1013 and compresses the limiting spring 1015 until the end of the first limiting block 1017 exceeds the first limiting groove 1018. The limiting spring 1015 rebounds to make the first limiting block 1017 lock the third movable block 1012. At this time, the fixing of the hammer head is completed. When disassembling the hammer head, pinch the two groups of first arc-shaped blocks 1019. At this time, the first limiting block 1017 no longer restricts the movement of the third movable block 1012. The third movable block 1012 returns to its original position under the rebound of the return spring 1010. The two groups of clamping plates 1006 are attached, and the hammer head can be taken out.

[0047] The loaded hammer head moves under the rotation of the conveyor belt 8. During the movement, since the second large driving gear 1106 meshes with the annular gear 1109, the second large driving gear 1106 rotates. Thus, under the transmission of multiple groups of gears, the turntable 1101 rotates, thereby driving the hammer head to rotate. The rotating hammer head first contacts the lower grinding sand strip 5 and polishes its side surface, and then contacts the upper grinding sand strip 5 to polish its front surface. Then it passes through the through groove 1205. At this time, the second large driving gear 1106 disengages from the annular gear 1109, and the hammer head stops rotating. It is disassembled by the worker and put into the placing groove 1206, and enters the loading box 1208 under the guidance of the connecting plate 1201.
