Description

Technical Field

[0001] This invention relates to the field of flywheel drilling technology, and in particular to a lathe for machining metal parts. Background Technology

[0002] A flywheel is a mechanical device used to store rotational kinetic energy during rotational motion. It is used in many fields, such as engines, compressors, and mechanical equipment.

[0003] In small and medium-sized factories with low levels of automation, the flywheel needs to be fixed before drilling holes in the flywheel of a car clutch. The drilling process is divided into vertical fixing and horizontal fixing. The requirements for drilling in the two methods are different. For small and medium-sized factories with low precision, vertical drilling is more common. The flywheel is placed on the slide rail, the position of the fixing unit is adjusted, the flywheel is clamped and fixed on the fixing unit, and then the drilling unit is started to drill holes in the fixed flywheel.

[0004] However, before the actual drilling operation, the workers need to pick up the flywheel and align it with the center of the fixed unit on the equipment, adjust the position of the fixed unit and the flywheel, fix the flywheel and manually rotate the flywheel, use a self-made detection device to closely observe whether there is any deviation when the flywheel rotates, and use a hammer to tap the flywheel at the deviation position.

[0046] As shown in Figures 1 to 14 The embodiment of the present application provides a lathe for metal piece processing, which comprises a lathe body 1 and a workbench 2, the top of the workbench 2 is slidably connected with a positioning clamping piece 3, the outer wall of the positioning clamping piece 3 is attached with a flywheel 4, the outer wall of the end of the positioning clamping piece 3 is clamped with a placing column 21, and the outer wall of the positioning clamping piece 3 away from the placing column 21 is clamped with a fitting plate 26; a positioning assembly is used for assisting the placement and fixation of the flywheel 4, the positioning assembly is connected with the positioning clamping piece 3, the top of the positioning clamping piece 3 is of an arc structure, the bottom is of a clamping sliding structure, the placing column 21 is of a gradual change structure, the fitting plate 26 is of an arc design, and the middle position of the outer wall of the positioning clamping piece 3 is provided with a clamping groove, the lathe body 1, the workbench 2 and the flywheel 4 are existing structures, and thus are not described in detail, the positioning clamping piece 3 is made of metal material, a small amount of lubricating oil can be applied to the bottom before sliding, so as to reduce the friction between the bottom of the positioning clamping piece 3 and the top of the workbench 2, facilitate the adjustment of the staff, and the positioning clamping piece 3 is symmetrical and has two.

[0047] Work flow: firstly, the flywheel 4 and related equipment are selected and inspected, then the flywheel 4 is placed on a special punching device, generally magnetic or clamped and fixed, after the flywheel 4 is fixed, the flywheel 4 is punched, the punching direction and track are according to the design requirements of the flywheel 4, and the cooling liquid is matched during drilling to prevent the drill from overheating, after the drilling is completed, the hole diameter and roundness are measured by using professional measuring tools, and finally the flywheel 4 surface and drilling debris are collected and cleaned.

[0048] By setting the positioning assembly, the worker does not need to continuously hold the flywheel 4 during the operation process, reducing the difficulty in the operation process, and when fixing the flywheel 4, the placement column 21 can be used to quickly correct the rotation track of the flywheel 4, reducing the step of manual knocking correction of the worker, reducing the workload of the worker, and improving the working efficiency of the flywheel 4 drilling.

[0049] As Figures 5 to 10 , the positioning assembly comprises a contact block 5 fixedly connected to the outer wall of the positioning clamp 3, a first stress plate 6 fixedly connected to the outer wall of the positioning clamp 3, a second stress plate 7 attached to the middle position of the bottom of the first stress plate 6, a fixed plate 11 fixedly connected to both sides of the second stress plate 7, a side arc plate 8 fixedly connected to the outer wall of the positioning clamp 3, a sinking groove 9 opened in the middle position of the second stress plate 7, an adaptive groove 10 opened in both ends of the second stress plate 7, a clamping hole 12 opened in both ends of the second stress plate 7, a weakening part 13 opened in the middle position of the outer wall of the second stress plate 7 close to the side arc plate 8, a rotating column 14 fixedly connected to the bottom of the side arc plate 8, a limiting buckle 15 fixedly connected to the outer wall of the rotating column 14, an adjusting plate 16 fixedly connected to the outer wall of the top of the rotating column 14, an adaptive part 17 fixedly connected to the outer wall of the top of the adjusting plate 16, a clamping column 18 fixedly connected to the outer wall of the top of the adjusting plate 16, a lower tension plate 19 fixedly connected to both ends of the second stress plate 7, an upper tension plate 20 fixedly connected to the middle position of the outer wall of the top of the adjusting plate 16, the contact block 5 is made of rubber material, the middle position of the first stress plate 6 is protruded downward, the outer wall of the fixed plate 11 is fixedly connected to the inner wall of the bottom of the positioning clamp 3, the both ends of the rotating column 14 are provided with fixed columns fixedly connected to the bottom of the side arc plate 8, the size of the adaptive part 17 is matched with the size of the adaptive groove 10, the size of the clamping column 18 is matched with the size of the clamping hole 12, the lower tension plate 19 and the upper tension plate 20 are clamped with each other, the distance between the two contact blocks 5 is less than the distance between the two positioning clamps 3, the first stress plate 6 and the second stress plate 7 are made of metal material, the hardness of the second stress plate 7 is greater than the hardness of the first stress plate 6, the middle position of the top of the side arc plate 8 is provided with a placement groove, the side arc plate 8, the second stress plate 7 and the fixed plate 11 jointly connect the two positioning clamps 3 to each other to form a whole, the top of the adjusting plate 16 and both ends of the second stress plate 7 are clamped with each other, and the clamping column 18, the lower tension plate 19 and the upper tension plate 20 are clamped between each other to form a semi-fixed state that can be shaken.

[0050] By the above structure, the staff smears a small amount of lubricating oil on the bottom of the positioning clamping piece 3, then places the positioning clamping piece 3 horizontally on the top of the workbench 2, and can slide on the outer wall of the positioning clamping piece 3 by hand before the flywheel 4 is placed. On the one hand, it checks whether the positioning clamping piece 3 shakes obviously during sliding, and on the other hand, the lubricating oil at the bottom of the positioning clamping piece 3 can also be slid to the position on the top of the workbench 2, improving the sliding effect between the workbench 2 and the positioning clamping piece 3. Then stop the sliding of the positioning clamping piece 3 and place the flywheel 4 in the middle position of the positioning clamping piece 3. When placing, ensure that the bottom of the flywheel 4 is in the middle position of the two positioning clamping pieces 3. Whether the flywheel 4 is correctly placed in the middle position of the two positioning clamping pieces 3, when the outer edge of the flywheel 4 contacts the first stress plate 6, the first stress plate 6 will deform downward and approach the second stress plate 7 due to the weight of the flywheel 4 being greater than the pressure that the first stress plate 6 can withstand. The shape of the middle part of the first stress plate 6 is "U", so that the flywheel 4 will automatically be in the middle position of the first stress plate 6 during the placement from top to bottom. The first stress plate 6 will continuously move downward during the continuous pressure of the flywheel 4 on the first stress plate 6. When the bottom of the first stress plate 6 contacts the second stress plate 7, it will continue to move downward along the middle sunken groove 9 of the second stress plate 7. When the first stress plate 6 presses towards the sunken groove 9, the second stress plate 7 will also deform. The deformation of the second stress plate 7 will cause the adjustment plates 16 at both ends to also move. At this time, reference can be made to Figure 6 If the middle position of the second stress plate 7 is pressed downward, the two ends of the second stress plate 7 will be raised, and from Figure 9As can be seen, the adjusting plate 16 is pulled up with the second force plate 7 at both ends of the adapter 17, the clamping column 18 and the lower tension plate 19, and further rotates the column 14 due to the pulling of the adjusting plate 16. The limiting buckle 15 gradually approaches the middle position of the bottom of the side arc plate 8 and is in contact, thereby limiting the further rotation of the rotating column 14, and the large-angle rotation of the rotating column 14 cannot be realized. If the adjusting plate 16 continues to be pulled up after the rotation is completed, the upward force will be concentrated on the limiting buckle 15 and the adjusting plate 16, and the mutual clamping and pulling effect between the lower tension plate 19 and the upper tension plate 20 will be obvious with the upward pulling of the adjusting plate 16. In actual operation, the weight of the flywheel 4 itself is large, and after being placed on the first force plate 6, it will sink in a very short time, and the pressure will be gradually transmitted from the first force plate 6 to the second force plate 7 and continue along the adjusting plate 16, the rotating column 14 and the limiting buckle 15, and then the adapter 17, the clamping column 18 will share part of the pressure under the clamping effect, and then the bottom of the side arc plate 8 will be bent upwards. In order to reduce the bending marks of the side arc plate 8 after multiple uses, which affects the overall strength of the side arc plate 8, a weakening portion 13 is provided in the middle position of the side arc plate 8 for actively weakening the bending marks. After the flywheel 4 is completely placed on the first force plate 6 by the worker, after a series of pressure transmission, the bottom of the flywheel 4 will be directly placed on the placement groove on the top of the side arc plate 8, at this time the first force plate 6 is in the maximum downward deformation state, the sinking groove 9 in the middle position of the second force plate 7 holds the deformed first force plate 6 as a buffer effect, and the remaining parts have been described in detail in the process of pressure transmission, and are in normal working state. At this time, the flywheel 4 can be fixed in the middle position of the two positioning clamps 3, and the outer edge of the bottom of the flywheel 4 will not contact the top of the workbench 2, avoiding the subsequent sliding of the positioning clamps 3 due to the contact of the outer edge of the flywheel 4 on the workbench 2. The contact block 5 is made of rubber material and can deform more, and when the flywheel 4 is in a stable state, the two contact blocks 5 will also completely fit on the outer wall of the flywheel 4, limiting the flywheel 4 from the middle position close to the flywheel 4. The flywheel 4 is fixed from the bottom and the middle, so that the flywheel 4 will not shake during the sliding of the positioning clamps 3.

[0051] It is worth mentioning that when the flywheel 4 is placed downward, the pressure of the flywheel 4 will cause the tension of the lower tension plate 19 and the upper tension plate 20. Since the upper tension plate 20 is fixed at both ends of the second stress plate 7, and the lower tension plate 19 is fixed on the side of the top of the side arc plate 8, the downward pressure of the second stress plate 7 will make the tension of the upper tension plate 20 better, and the lifting effect of the adjusting plate 16 will also make the tension of the lower tension plate 19 better, and the clamping effect of the adjusting plate 16 and the second stress plate 7 is better. At the same time, the semi-fixed structure between the adjusting plate 16 and the second stress plate 7 is also more conducive to the placement of the flywheel 4.

[0052] By setting the weakening part 13, the rotating column 14 and the limiting buckle 15 in the positioning assembly, when the adjusting plate 16 is subjected to force and is pulled upward, the rotating column 14 will rotate under the upward pulling force, and the upward pulling will also cause the bottom of the side arc plate 8 to bend upward. The weakening part 13 can well weaken the bending folds formed after the bottom of the side arc plate 8 is bent, and the limiting of the limiting buckle 15 can relieve the folds at the weakening part 13, reduce bending fatigue, and improve the service life of the equipment.

[0053] By setting the contact block 5, the first stress plate 6, the second stress plate 7 and the sinking groove 9 in the positioning assembly, when the flywheel 4 is placed on the first stress plate 6, the shape of the first stress plate 6 makes the flywheel 4 gradually in the middle position of the two positioning clamps 3, and the first stress plate 6 gradually contacts with the second stress plate 7 and the sinking groove 9 in the process of continuous pressing, so as to relieve the pressure brought by the weight of the flywheel 4, make the flywheel 4 more smoothly and conveniently in the process of placement, and the contact block 5 can better limit the position of the flywheel 4, further improve the stability of the flywheel 4 when placed.

[0054] As Figures 11 to 14As shown, the two ends of the positioning clamp 3 are provided with a push groove 23, the inner wall of the push groove 23 is slidably connected with a push plate 22, the middle position of the outer wall of the placement column 21 is fixedly connected with an adaptive block 24, the inner wall of the positioning clamp 3 is installed with a resisting column 25, the outer wall of the positioning clamp 3 is connected with a limiting column 27, the outer wall of the fitting plate 26 is fixedly connected with a protective sleeve 28, the middle position of the outer wall of the fitting plate 26 close to the positioning clamp 3 is fixedly connected with a deformation ring 29, the size of the middle position of the placement column 21 is matched with the size of the push groove 23, the resisting column 25 is provided with an elastic rope, the end of the elastic rope away from the resisting column 25 is fixedly connected with the inner wall of the positioning clamp 3, the adaptive block 24 is spirally arranged on the middle position of the outer wall of the placement column 21, the size of the clamping groove is consistent with the size of the small diameter of the placement column 21, the inside of the deformation ring 29 is designed as hollow, the placement column 21 is provided with a degree value close to the large diameter end, the inner wall size of the positioning clamp 3 in the push groove 23 is different, according to the figure, the left push groove 23 is designed smaller than the right push groove 23, the resisting column 25 is circumferentially arranged in the inside of the right push groove 23, in the initial state, the resisting column 25 is in the same static state as the push plate 22, if the positioning clamp 3 is inclined, the push plate 22 will slide outward, and the resisting column 25 is fixed with a traction rope, and cannot slide by gravity.

[0055] By the above structure, after the flywheel 4 is placed, the large-diameter end of the placement column 21 is held in hand, and the placement column 21 is inserted from one side of the positioning clamp 3, the adapter block 24 on the placement column 21 is aligned with the slot hole on the pushing groove 23, and the adapter block 24 is in threaded distribution. During the pushing process, the adapter block 24 will be in contact with and pressed by the resistance column 25 one by one, so that the placement column 21 drives the adapter block 24, the adapter block 24 slides and presses in the inside of the positioning clamp 3 and drives the resistance column 25 to slide, after the resistance column 25 slides, the traction rope fixed on the resistance column 25 is pulled, then the sliding of the resistance column 25 will press the pushing plate 22, so that the pushing plate 22 also slides in the inside of the pushing groove 23, until the small-diameter end of the placement column 21 slides out of the inside of the pushing groove 23 and moves to the middle position of the abutting plate 26. When the small-diameter end of the placement column 21 does not abut against the deformation ring 29 in the middle position of the abutting plate 26, the abutting plate 26 is clamped and fixed in the position close to the pushing groove 23 of the positioning clamp 3 by the limiting column 27, so that the abutting plate 26 is clamped and fixed on the side of the positioning clamp 3 when the small-diameter end of the placement column 21 does not come out of the pushing groove 23, and the small-diameter end of the placement column 21 directly abuts against the deformation ring 29 in the middle position of the abutting plate 26 after coming out, so as to gradually push the limiting column 27 out of the inner wall of the positioning clamp 3. It is worth mentioning that the limiting column 27 will not completely separate from the inside of the positioning clamp 3, which ensures the relative stability of the abutting plate 26, and the small-diameter end of the placement column 21 will continuously approach the deformation ring 29 and be pressed, since the inside of the deformation ring 29 is hollow, the small-diameter end of the placement column 21 is clamped with the inner wall of the deformation ring 29, until the abutting plate 26 on the side of the flywheel 4 is abutted on the surface of the flywheel 4, the pushing of the placement column 21 is stopped, and the value of the large-diameter end of the placement column 21 is observed at this time. After one side of the positioning clamp 3 is completed, the other side is the same, and finally the positioning clamp 3 is slid to the fixed unit for fixation. At this time, the flywheel 4 can move vertically, which is convenient for fixation. It is worth mentioning that after the flywheel is fixed on the fixed unit, the positioning clamp 3 is slid in the opposite direction until it falls off from the top of the workbench 2 and is taken off.

[0056] Further illustrate, in the process of pushing the placement column 21 to drive the moving of the fitting plate 26, the protective sleeve 28 will gradually close to and adhere to the outer wall of the flywheel 4, and is clamped in the deformation ring 29 after the small diameter end of the placement column 21 is exposed, and the offset of the flywheel 4 is continuously pushed by the fitting plate 26, since the flywheel 4 at this time is only placed and has not been fine-tuned by the worker, part of the flywheel 4 still exists the situation that is not on the same plane when rotating, at this time, the fitting plate 26 can be used to ensure that the values on the two sides of the placement column 21 of the positioning clamp 3 remain consistent, so that the flywheel 4 will not be offset when rotating, and the operation can be carried out after the flywheel 4 is placed, and the placement column 21 can be directly pushed to the position of the pushing groove 23.

[0057] By setting the placement column 21, the pushing plate 22, the pushing groove 23, the adaptive block 24, the abutting column 25 and the fitting plate 26, after the flywheel 4 is fixed, the rotating surface of the flywheel 4 is adjusted, the flywheel 4 is pushed by the placement column 21, so that the two sides of the flywheel 4 are at the same value, so that when the flywheel 4 is clamped in the fixing unit, the flywheel 4 is slightly rotated to observe whether there is an offset when rotating, effectively improving the efficiency of the worker's adjustment and ensuring the progress of drilling the flywheel 4.

[0058] The working principle of the technical scheme provided by the application is as follows:

[0059] The worker applies a small amount of lubricating oil to the bottom of the positioning clamp 3, and then places the positioning clamp 3 horizontally on the top of the workbench 2. Before placing the flywheel 4, the worker can slide the positioning clamp 3 by hand on the outer wall of the positioning clamp 3. On the one hand, the worker checks whether the positioning clamp 3 shakes obviously during sliding. On the other hand, the lubricating oil at the bottom of the positioning clamp 3 can also slide to the position on the top of the workbench 2, improving the sliding effect between the workbench 2 and the positioning clamp 3. Then, the worker stops the sliding of the positioning clamp 3 and places the flywheel 4 in the middle position of the positioning clamp 3. When placing, the worker ensures that the bottom of the flywheel 4 is in the middle position of the two positioning clamps 3. Whether the flywheel 4 is correctly placed in the middle position of the two positioning clamps 3 or not, when the outer edge of the flywheel 4 contacts the first stress plate 6, the first stress plate 6 will deform downward and approach the second stress plate 7 due to the weight of the flywheel 4 being greater than the pressure that the first stress plate 6 can withstand. The shape of the middle part of the first stress plate 6 is "U", so that the flywheel 4 will automatically be in the middle position of the first stress plate 6 during the placement from top to bottom. The first stress plate 6 will continuously move downward during the continuous pressure of the flywheel 4 on the first stress plate 6. When the bottom of the first stress plate 6 contacts the second stress plate 7, the first stress plate 6 will continue to move downward along the middle sinking groove 9 of the second stress plate 7. When the first stress plate 6 presses toward the sinking groove 9, the second stress plate 7 will also deform. The deformation of the second stress plate 7 will also cause the adjustment plates 16 at both ends to move. At this time, the worker can refer to the position of the flywheel 4 in the middle of the two positioning clamps 3, and then the worker can use the fitting plate 26 to push the flywheel 4 to the middle of the two positioning clamps 3. Figure 6, if the middle position of the second force plate 7 is pressed downward, the two ends of the second force plate 7 will be raised, and the first force plate 6 will be deformed downward Figure 9 As can be seen from the above, the adjusting plate 16 is pulled up with the two ends of the second force plate 7 being raised under the clamping and fixing of the adapter 17, the clamping column 18 and the lower tension plate 19, and the rotating column 14 will rotate due to the pulling of the adjusting plate 16. The limiting buckle 15 will gradually approach the middle position of the bottom of the side arc plate 8 and resist, thereby limiting the further rotation of the rotating column 14, and the large-angle rotation of the rotating column 14 cannot be realized. If the adjusting plate 16 continues to be pulled up after the rotation is completed, the upward force will be concentrated on the limiting buckle 15 and the adjusting plate 16, and the mutual clamping and pulling effect between the lower tension plate 19 and the upper tension plate 20 will be obvious with the upward pulling of the adjusting plate 16. In actual operation, the flywheel 4 itself is heavy, and after being placed on the first force plate 6, it will sink in a very short time, and the pressure will be gradually transmitted from the first force plate 6 to the second force plate 7 and continue along the adjusting plate 16, the rotating column 14 and the limiting buckle 15, and then the adapter 17 and the clamping column 18 will share part of the pressure under the clamping action, and then the bottom of the side arc plate 8 will be bent upward. In order to reduce the bending and creasing of the side arc plate 8 after multiple uses, affecting the overall strength of the side arc plate 8, a weakening portion 13 is provided in the middle position of the side arc plate 8 for actively weakening the bending and creasing. After the flywheel 4 is completely placed on the first force plate 6 by the worker, after a series of pressure transmission, the bottom of the flywheel 4 will be directly placed on the placement groove on the top of the side arc plate 8, at this time the first force plate 6 is in the maximum downward deformation state, the sinking groove 9 in the middle position of the second force plate 7 holds the deformed first force plate 6 as a buffer effect, and the remaining parts are in normal working state during the pressure transmission process, which is described in detail. At this time, the flywheel 4 can be fixed in the middle position of the two positioning clamps 3, and the outer edge of the bottom of the flywheel 4 will not touch the top of the workbench 2, avoiding the contact of the outer edge of the flywheel 4 with the workbench 2 during the sliding of the positioning clamps 3, so that the flywheel 4 cannot slide normally. Finally, the contact block 5 is made of rubber material and can deform more, and when the flywheel 4 is in a stable state, the two contact blocks 5 will also completely fit on the outer wall of the flywheel 4, limiting the flywheel 4 from the middle position close to the flywheel 4. The flywheel 4 is fixed from the bottom and the middle, so that the flywheel 4 will not shake during the sliding of the positioning clamps 3.

[0060] After the flywheel 4 is placed, the large-diameter end of the placement column 21 is held, and the placement column 21 is inserted from one side of the positioning clamp 3, the adapter block 24 on the placement column 21 is pushed into the slot hole on the pushing groove 23, and the above-mentioned resistance column 25 and pushing plate 22 are distributed in a circular array, and the adapter block 24 is distributed in a threaded manner. During the pushing process, the adapter block 24 will be in contact with and pressed against the resistance column 25 one by one, so that the placement column 21 drives the adapter block 24, the adapter block 24 slides in the positioning clamp 3 and is pressed to drive the resistance column 25 to slide, after the resistance column 25 slides, the traction rope fixed on the resistance column 25 is pulled, and then the sliding of the resistance column 25 presses the pushing plate 22, so that the pushing plate 22 also slides in the pushing groove 23, until the small-diameter end of the placement column 21 slides out of the inside of the pushing groove 23 and moves to the middle position of the abutting plate 26. When the small-diameter end of the placement column 21 does not abut against the deformation ring 29 in the middle position of the abutting plate 26, the abutting plate 26 is fixed by the limiting column 27 clamped in the position close to the pushing groove 23 of the positioning clamp 3, so that when the small-diameter end of the placement column 21 does not come out of the pushing groove 23, the abutting plate 26 is clamped and fixed on the side of the positioning clamp 3, and after the small-diameter end of the placement column 21 comes out, it directly abuts against the deformation ring 29 in the middle position of the abutting plate 26, thereby gradually pushing the limiting column 27 out of the inner wall of the positioning clamp 3. It is worth mentioning that the limiting column 27 will not completely separate from the inside of the positioning clamp 3, which ensures the relative stability of the abutting plate 26, and the small-diameter end of the placement column 21 will continuously approach the deformation ring 29 and be pressed. Since the inside of the deformation ring 29 is hollow, the small-diameter end of the placement column 21 can be clamped with the inner wall of the deformation ring 29, until the abutting plate 26 on the side of the flywheel 4 is abutted on the surface of the flywheel 4, and the pushing of the placement column 21 is stopped. At this time, observe the value of the large-diameter end of the placement column 21, and the other side is the same as the above, and finally the positioning clamp 3 is slid to the fixed unit for fixation. At this time, limited by the middle and bottom, the flywheel 4 can move vertically to facilitate fixation.
