Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a reaming mechanism for processing chain eyelets. Background Art

[0002] Chain eyelet reaming usually refers to a technique for machining the holes of chain rings during the chain manufacturing process. It is suitable for hole machining of various mechanical parts, especially in the field of precision machinery with high requirements. Reaming usually involves the use of special reaming tools, which can further fine-tune the hole wall after drilling or reaming, and remove tiny metal layers to achieve the required dimensional accuracy and surface roughness. Before reaming, drilling and reaming are usually performed to form a preliminary hole, and then a reamer is used for finishing.

[0003] However, when processing the existing chain holes, the inner wall of the chain holes needs to be subjected to secondary fine processing, and the processing precision is required to be high. When processing the existing chain holes, the chain is generally clamped by a vise, and the vise still needs to be manually operated during this process. The processing precision is poor and the shape of the chain is easily damaged. At the same time, when processing the chain holes, cutting fluid is required for lubrication, which results in a waste of cutting fluid and an increase in processing costs. Therefore, the present application provides a reaming mechanism for chain hole processing to meet the needs. Summary of the invention

At the same time, the physical properties of nitrile rubber, such as good oil resistance and wear resistance, are utilized to ensure the side positioning effect of the chain while increasing the service life of the rubber drum, and avoiding secondary damage to the shape of the chain.

[0021] By setting up a spraying component and utilizing the continuous downward force of the reamer during machining, the cutting fluid can be sprayed out synchronously. At the same time, the rotation effect of the reamer during machining is utilized to squeeze the pressure rod at intervals to achieve the reciprocating rotation effect of the nozzle. At the same time, the rotation effect of the reamer itself is coordinated to ensure that the cutting fluid can be evenly sprayed onto the surface of the reamer, thereby ensuring the lubrication effect of the cutting fluid on the reamer and the chain holes while avoiding the waste of the cutting fluid. At the same time, in conjunction with the circulation component, the cutting fluid is filtered by providing a guide pipe and a guide groove.

[0022] By setting up a filter plate, the metal debris carried in the cutting fluid is intercepted to prevent the residual metal debris in the cutting fluid from affecting the processing effect of the chain holes. At the same time, through the liquid conversion between the liquid inlet barrel and the liquid storage barrel, the "filtration-use" circulation treatment of the cutting fluid is realized, which reduces the cost of cutting fluid while ensuring the chain processing accuracy.

[0041] like Figures 1 to 9 As shown, an embodiment of the present invention provides a reaming mechanism for processing chain holes, including a processing machine tool 1, a control module 2 is fixedly installed on one side of the processing machine tool 1, a processing plate 3 is installed in the middle of the inner wall of the processing machine tool 1, an electric slide rail 4 is installed on the top of the inner wall of the processing machine tool 1, a sliding base 5 is sleeved on the outer surface of the electric slide rail 4, a cylinder 6 is installed on the top of the sliding base 5, a push plate 7 is connected to the bottom end of the cylinder 6, a trigger plate 50 is installed at the bottom end of the push plate 7, a motor 8 is fixedly installed at one end of the push plate 7, and a reamer 9 is connected to the bottom end of the motor 8; a positioning component 10, a positioning component 10 is installed on the top of the processing plate 3, and the positioning component 10 is used to position the chain; a spraying component 11, a spraying component 11 is installed at the bottom end of the sliding base 5, and the spraying component 11 is used to spray cutting fluid; a circulation component 12, a circulation component 12 is installed at the bottom end of the processing plate 3, and the circulation component 12 is used to cooperate with the spraying component 11 to circulate the cutting fluid.

[0042] By setting the positioning component 10, the processing accuracy of the reamer 9 when processing the chain holes is guaranteed. By setting the spraying component 11, it is guaranteed that the cutting fluid can be evenly sprayed onto the surface of the reamer 9 to ensure the processing accuracy of the chain. By setting the circulation component 12, the sustainable use of the cutting fluid when the reamer 9 processes the chain holes is achieved.

[0043] like Figure 3 to Figure 4 As shown, the positioning assembly 10 includes a mounting base 101, which is fixedly mounted on the top of the processing plate 3, and a positioning groove 102 is installed at the center of the top of the mounting base 101. A slide rail 103 is installed on the inner wall of the mounting base 101, and the number of the slide rails 103 is set to two groups. The two groups of slide rails 103 are installed on the inner wall of the mounting base 101 in the same axial direction. A sliding seat 104 is sleeved on the outer surface of the slide rail 103, and the number of the sliding seat 104 is set to two groups. The two groups of sliding seats 104 are both sleeved on the outer surface of the slide rail 103. A rubber roller 105 is installed on the top of the sliding seat 104, and the surface material of the rubber roller 105 is set to nitrile rubber. One end of one group of sliding seats 104 is connected to an electric push rod 1040, and the electric push rod 1040 is fixedly mounted on one end of the processing plate 3. A rack 106 is installed on one side of the inner wall of the sliding seat 104, and the number of the rack 106 is set to two groups. The two sets of racks 106 are respectively installed on one side of the inner wall of the two sets of sliding seats 104, and a flat gear 107 is meshed between the two sets of racks 106. The flat gear 107 is installed at the center of the top of the mounting base 101.

[0044] The operator first places the chain on the positioning groove 102 at the top of the mounting base 101, and then the control module 2 controls the electric push rod 1040 to start. After the electric push rod 1040 is started, it pushes one group of sliding seats 104 to slide along the direction of the slide rail 103. While the sliding of this group of sliding seats 104, it drives one group of rack gears 106 to slide synchronously. While the sliding of this group of rack gears 106, it engages with the rotation of the flat gear 107. While the flat gear 107 rotates, it engages with another group of rack gears 106. Under the rotation action of the flat gear 107, the other group of rack gears 106 slides in the opposite direction. While the sliding of the other group of rack gears 106 in the opposite direction, it drives the other group of sliding seats 104 to slide in the opposite direction, so that the two groups of sliding seats 104 approach each other along the direction of the slide rail 103. While the two groups of sliding seats 104 approach each other, they drive the rubber drum 105 at the top to approach each other synchronously. When the two groups of sliding seats 104 slide close to each other, they drive the rubber drum 105 at the bottom to approach and contact the side of the chain to position the chain.

[0045] By setting the coordination between the rack 106 and the flat gear 107, before processing the chain holes, the side of the chain is pre-positioned by the sliding seat 104 and the rubber drum 105 to ensure the processing accuracy of the reamer 9 when processing the chain holes, and further ensure the processing effect of the reamer 9 on the chain holes. At the same time, the physical properties of nitrile rubber, such as good oil resistance and wear resistance, are utilized to improve the service life of the rubber drum 105 while ensuring the positioning effect of the chain side.

[0046] like Figures 5 to 7 As shown, the spray assembly 11 includes a liquid inlet barrel 111, which is fixedly installed at the bottom of the sliding base 5, and a piston disc 112 is slidably fitted on the inner wall of the liquid inlet barrel 111. A pressure plate 113 is installed on the top of the piston disc 112, and a spring 114 is installed on one side of the inner wall of the pressure plate 113. The bottom end of the spring 114 is elastically connected to the top of the liquid inlet barrel 111, and a one-way valve 115 is installed through the bottom of the liquid inlet barrel 111. The top of the one-way valve 115 is connected to a liquid outlet ring 116 through a hose. The liquid outlet ring 116 is fixedly installed on one side of the trigger plate 50, and a nozzle 117 is connected to the inner wall of the liquid outlet ring 116. The number of nozzles 117 is set to multiple groups, and multiple groups of nozzles 117 is arranged at equal angles on the inner wall of the liquid outlet ring 116, a pressure rod 118 is installed on one side of the top end of the liquid outlet ring 116, an elastic telescopic rod 119 is installed on one side of the outer surface of the pressure rod 118, the bottom end of the elastic telescopic rod 119 is installed on the top end of the liquid outlet ring 116, the pressure rod 118 is elastically installed on one side of the top end of the liquid outlet ring 116 through the elastic telescopic rod 119, a rack 2 1110 is fixedly installed on the bottom end of the pressure rod 118, one side of the rack 2 1110 is meshed with a flat gear 2 1111, the flat gear 2 1111 is sleeved on the outer surface of the nozzle 117, the top end of the pressure rod 118 is in contact with a wedge block 1113, and the wedge block 1113 is sleeved on the outer surface of the connecting part of the reamer 9 and the motor 8.

[0047] Subsequently, the control module 2 controls the cylinder 6 and the motor 8 to start. After the motor 8 is started, it drives the reamer 9 to rotate. At the same time, the cylinder 6 pushes the push plate 7 to slide downward. When the push plate 7 slides, it drives the motor 8 and the reamer 9 to slide synchronously. When the reamer 9 slides, it approaches the inner wall of the hole of the chain. Under the action of the rotation of the reamer 9, the inner wall of the hole of the chain is processed.

[0048] When the push plate 7 slides, it drives the trigger plate 50 to slide synchronously. When the trigger plate 50 slides, it approaches and pushes the pressure plate 113 to slide downward. When the pressure plate 113 slides downward, it squeezes the spring 114, causing the spring 114 to contract under force. When the pressure plate 113 slides, it drives the piston disc 112 to slide and squeeze in the internal cavity of the liquid inlet barrel 111, and squeezes the cutting fluid stored in the liquid inlet barrel 111 into the liquid outlet ring 116 through the one-way valve 115 at the bottom of the liquid inlet barrel 111. Under the continuous squeezing action of the piston disc 112, the cutting fluid in the liquid outlet ring 116 is sprayed out through the nozzle 117.

[0049] When the motor 8 drives the reamer 9 to rotate synchronously, the connection part of the reamer 9 and the motor 8 drives the wedge block 1113 to rotate synchronously. While the wedge block 1113 rotates, it squeezes the top of the plurality of pressure rods 118 at intervals. When the pressure rods 118 are squeezed by the wedge block 1113, the pressure rods 118 drive the rack 2 1110 at the bottom to slide downward. Under the sliding action of the rack 2 1110, the flat gear 2 1111 rotates. While the flat gear 2 1111 rotates, it drives the nozzle 117 through the collar 1112. Synchronous rotation. Similarly, when the wedge block 1113 is out of contact with the pressure rod 118, under the elastic action of the elastic telescopic rod 119, the elastic telescopic rod 119 drives the pressure rod 118 to slide upward and reset, and the pressure rod 118 drives the rack 2 1110 to slide upward and reset, and the rack 2 1110 drives the flat gear 2 1111 and reverse rotation to reset, and the flat gear 2 1111 drives the ring 1112 to realize the reciprocating swing effect of the nozzle 117, so that the cutting fluid sprayed by the nozzle 117 evenly covers the surface of the reamer 9.

[0050] When one of the holes in the chain is processed, the control module 2 turns off the motor 8 to stop the reamer 9, and the cylinder 6 drives the push plate 7 to slide in the opposite direction. The push plate 7 slides and drives the motor 8 and the reamer 9 to slide synchronously, so that the reamer 9 is out of contact with the processed chain hole, and the push plate 7 slides in the opposite direction and drives the trigger plate 50 to slide synchronously. The trigger plate 50 slides and loses contact with the pressure plate 113. Under the elastic action of the spring 114, the spring 114 stretches and resets. The spring 114 stretches and drives the pressure plate 113 to slide in the opposite direction. The pressure plate 113 slides in the opposite direction and drives the piston disc 112 to slide and suck in the internal cavity of the liquid inlet barrel 111. Under the suction action of the piston disc 112, the cutting fluid in the liquid storage barrel 124 and the infusion tube 125 is sucked into the liquid inlet barrel 111, thereby completing the replenishment of the cutting fluid in the liquid inlet barrel 111.

[0051] By providing a liquid inlet barrel 111 and a piston disc 112, the continuous downward force of the reamer 9 during processing is utilized to realize synchronous ejection of the cutting fluid. At the same time, the rotation effect of the reamer 9 during rotation processing is utilized to squeeze the pressure rod 118 at intervals to realize the reciprocating rotation effect of the nozzle 117. At the same time, in conjunction with the rotation effect of the reamer 9 itself, it is ensured that the cutting fluid can be evenly sprayed onto the surface of the reamer 9. At the same time, in conjunction with the circulation component 12, the cutting fluid can be circulated while ensuring the processing effect of the reamer 9 on the chain, thereby realizing sustainable use of the cutting fluid when the reamer 9 is processing the chain holes.

[0052] like Figures 8 to 9As shown, the circulation component 12 includes a guide tube 121, which is nested and installed on the top of the mounting base 101. The number of the guide tubes 121 is set to two groups, and the two groups of guide tubes 121 are nested and installed on the top of the mounting base 101 in the same axial direction. A guide groove 122 is installed on the top of the inner wall of the guide tube 121, and a filter box 123 is connected to the bottom end of the guide tube 121. A filter plate 1230 is nested and installed on the inner wall of the filter box 123. The side of the filter plate 1230 contacts the inner wall of the filter box 123, and a liquid storage barrel 124 is connected to the bottom end of the filter box 123. The liquid storage barrel 124 is fixedly installed on the bottom end of the processing plate 3. A liquid infusion tube 125 is installed on the bottom end of the liquid storage barrel 124. Part of the surface of the liquid infusion tube 125 is nested and installed on the inner wall of the processing plate 3. The top of the liquid infusion tube 125 is connected to a one-way valve 126, and the one-way valve 126 is installed on one side of the bottom end of the liquid inlet barrel 111.

[0053] When the reamer 9 is processing the inner wall of the hole of the chain, the cutting fluid on the surface of the reamer 9 drips under the action of gravity and flows into the guide tube 121. While dripping, the cutting fluid takes away the metal debris generated when the reamer 9 processes the inner wall of the hole of the chain. Under the action of continuous spraying of the cutting fluid, the cutting fluid and the metal debris enter the guide tube 121 through the guide groove 122, and enter the filter box 123 under the action of the guide tube 121. Subsequently, the metal debris is retained on the surface of the filter plate 1230 under the filtering action of the filter plate 1230, and the filtered cutting fluid enters the liquid storage barrel 124 at the bottom of the filter box 123. When the chain processing is completed, the operator can pull the filter plate 1230 out of the filter box 123 to centrally process the metal debris retained on the surface of the filter plate 1230.

[0054] Similarly, when the cylinder 6 drives the push plate 7 to slide in the opposite direction into place, the control module 2 controls the electric slide rail 4 to start, so that the sliding base 5 slides along the direction of the electric slide rail 4. When the sliding base 5 slides, it drives the cylinder 6, the push plate 7, the motor 8 and the reamer 9 to slide synchronously. When the sliding base 5 slides into place, it continues to process the inner wall of another hole of the chain.

[0055] By providing the guide pipe 121 and the guide groove 122, the cutting fluid is filtered, and the metal debris carried in the cutting fluid is intercepted by the filter plate 1230, so as to realize the "filtration-use" circulation treatment of the cutting fluid, thereby reducing the use cost of the cutting fluid while ensuring the chain processing accuracy.

[0056] The working principle of the technical solution provided by the present invention is as follows:

[0057] The operator first places the chain on the positioning groove 102 at the top of the mounting base 101, and then the control module 2 controls the electric push rod 1040 to start. After the electric push rod 1040 is started, it pushes one group of sliding seats 104 to slide along the direction of the slide rail 103. While the sliding of this group of sliding seats 104, it drives one group of rack gears 106 to slide synchronously. While the sliding of this group of rack gears 106, it engages with the rotation of the flat gear 107. While the flat gear 107 rotates, it engages with another group of rack gears 106. Under the rotation action of the flat gear 107, the other group of rack gears 106 slides in the opposite direction. While the sliding of the other group of rack gears 106 in the opposite direction, it drives the other group of sliding seats 104 to slide in the opposite direction, so that the two groups of sliding seats 104 approach each other along the direction of the slide rail 103. While the two groups of sliding seats 104 approach each other, they drive the rubber drum 105 at the top to approach each other synchronously. When the two groups of sliding seats 104 slide close to each other, they drive the rubber drum 105 at the bottom to approach and contact the side of the chain to position the chain.

[0058] Subsequently, the control module 2 controls the cylinder 6 and the motor 8 to start. After the motor 8 is started, it drives the reamer 9 to rotate. At the same time, the cylinder 6 pushes the push plate 7 to slide downward. When the push plate 7 slides, it drives the motor 8 and the reamer 9 to slide synchronously. When the reamer 9 slides, it approaches the inner wall of the hole of the chain. Under the action of the rotation of the reamer 9, the inner wall of the hole of the chain is processed.

[0059] When the push plate 7 slides, it drives the trigger plate 50 to slide synchronously. When the trigger plate 50 slides, it approaches and pushes the pressure plate 113 to slide downward. When the pressure plate 113 slides downward, it squeezes the spring 114, causing the spring 114 to contract under force. When the pressure plate 113 slides, it drives the piston disc 112 to slide and squeeze in the internal cavity of the liquid inlet barrel 111, and squeezes the cutting fluid stored in the liquid inlet barrel 111 into the liquid outlet ring 116 through the one-way valve 115 at the bottom of the liquid inlet barrel 111. Under the continuous squeezing action of the piston disc 112, the cutting fluid in the liquid outlet ring 116 is sprayed out through the nozzle 117.

[0060] When the motor 8 drives the reamer 9 to rotate synchronously, the connection part of the reamer 9 and the motor 8 drives the wedge block 1113 to rotate synchronously. While the wedge block 1113 rotates, it squeezes the top of the plurality of pressure rods 118 at intervals. When the pressure rods 118 are squeezed by the wedge block 1113, the pressure rods 118 drive the rack 2 1110 at the bottom to slide downward. Under the sliding action of the rack 2 1110, the flat gear 2 1111 rotates. While the flat gear 2 1111 rotates, it drives the nozzle 117 through the collar 1112. Synchronous rotation. Similarly, when the wedge block 1113 is out of contact with the pressure rod 118, under the elastic action of the elastic telescopic rod 119, the elastic telescopic rod 119 drives the pressure rod 118 to slide upward and reset, and the pressure rod 118 drives the rack 2 1110 to slide upward and reset, and the rack 2 1110 drives the flat gear 2 1111 and reverse rotation to reset, and the flat gear 2 1111 drives the ring 1112 to realize the reciprocating swing effect of the nozzle 117, so that the cutting fluid sprayed by the nozzle 117 evenly covers the surface of the reamer 9.

[0061] When the reamer 9 is processing the inner wall of the hole of the chain, the cutting fluid on the surface of the reamer 9 drips under the action of gravity and flows into the guide tube 121. While dripping, the cutting fluid takes away the metal debris generated when the reamer 9 processes the inner wall of the hole of the chain. Under the action of continuous spraying of the cutting fluid, the cutting fluid and the metal debris enter the guide tube 121 through the guide groove 122, and enter the filter box 123 under the action of the guide tube 121. Subsequently, the metal debris is retained on the surface of the filter plate 1230 under the filtering action of the filter plate 1230, and the filtered cutting fluid enters the liquid storage barrel 124 at the bottom of the filter box 123. When the chain processing is completed, the operator can pull the filter plate 1230 out of the filter box 123 to centrally process the metal debris retained on the surface of the filter plate 1230.

[0062] When one of the holes in the chain is processed, the control module 2 turns off the motor 8 to stop the reamer 9, and the cylinder 6 drives the push plate 7 to slide in the opposite direction. The push plate 7 slides and drives the motor 8 and the reamer 9 to slide synchronously, so that the reamer 9 is out of contact with the processed chain hole, and the push plate 7 slides in the opposite direction and drives the trigger plate 50 to slide synchronously. The trigger plate 50 slides and loses contact with the pressure plate 113. Under the elastic action of the spring 114, the spring 114 stretches and resets. The spring 114 stretches and drives the pressure plate 113 to slide in the opposite direction. The pressure plate 113 slides in the opposite direction and drives the piston disc 112 to slide and suck in the internal cavity of the liquid inlet barrel 111. Under the suction action of the piston disc 112, the cutting fluid in the liquid storage barrel 124 and the infusion tube 125 is sucked into the liquid inlet barrel 111, thereby completing the replenishment of the cutting fluid in the liquid inlet barrel 111.

[0063] Similarly, when the cylinder 6 drives the push plate 7 to slide in the opposite direction into place, the control module 2 controls the electric slide rail 4 to start, so that the sliding base 5 slides along the direction of the electric slide rail 4. When the sliding base 5 slides, it drives the cylinder 6, the push plate 7, the motor 8 and the reamer 9 to slide synchronously. When the sliding base 5 slides into place, it continues to process the inner wall of another hole of the chain.
