Description

Technical Field

[0001] This invention relates to the field of parts processing technology, specifically a fixing device for parts processing. Background Technology

[0002] Parts processing involves using processes such as cutting, grinding, stamping, stretching, and molding to produce components that meet specific functional requirements from raw materials. Machine tools, forging presses, and injection molding machines are commonly used equipment in parts processing. The parts produced can be used in various mechanical equipment and production lines to improve the efficiency and quality of the manufacturing industry. During parts processing, it is necessary to fix and limit the parts to ensure that they do not deviate during processing, thus ensuring the processing accuracy. There are many types of shapes for the parts being processed, such as cylinders, cuboids, and irregular shapes.

[0003] Chinese Patent Publication No. CN114986211A discloses a rod-shaped part processing device and its processing method for mining machinery. In this solution, a second electric slide rail and a first connecting seat are used in conjunction to adjust the distance between the first connecting seats, enabling the clamping mechanism to clamp and fix rod-shaped parts of different lengths.

[0029] Please see Figures 1-11In this embodiment of the invention, a fixing device for machining parts includes a base plate 1. Fixing plates 2 are symmetrically arranged on both sides of the base plate 1. A fixing rod 3 is fixedly connected between the two fixing plates 2. A cleaning component 4 is slidably arranged on the fixing rod 3. Two vertical plates 5 and two sets of clamping components 6 are sequentially arranged between the two fixing plates 2. One set of clamping components 6 is located between the two vertical plates 5, and the other set is located between one of the vertical plates 5 and the fixing plate 2. A dust collection component 7 is arranged between each clamping component 6 and each vertical plate 5. A placement ring 8 is movably arranged at the top of each vertical plate 5. The rod-shaped part to be processed is placed on the placement ring 8 of the vertical plate 5. After placement, the clamping components 6 are used to clamp and limit the part. After the two sets of clamping components 6 have stabilized the workpiece, the placement ring 8 is moved downward along the vertical plate 5. The surface of the placement ring 8 does not contact the workpiece. At this time, the cleaning component 4 is activated. The cleaning component 4 moves along the fixed rod 3 to wipe and clean the outer surface of the workpiece. The fact that the placement ring 8 does not contact the workpiece makes it easy for the cleaning component 4 to clean the area where the workpiece contacts the placement ring 8. The cleaning component 4 moves from one side of the fixed plate 2 to the other side of the fixed plate 2. During the movement, the dust collection component 7 will work. The dust collection component 7 is located below the workpiece and can easily catch the debris generated during the workpiece processing, ensuring that the base plate 1 is clean and tidy. There are three sets of dust collection components 7, which are set between the vertical plate 5 and the clamping components 6. This can ensure that a large amount of waste debris generated during processing is caught.

[0030] See Figure 1 and Figure 5As shown, in this embodiment, preferably, the clamping assembly 6 includes a fixed frame 61, a fixed block 62 is fixedly disposed inside the fixed frame 61, a lifting rod 63 is slidably disposed inside the fixed block 62, inclined surfaces 64 are provided on both sides of the lifting rod 63, clamping rods 65 are axially symmetrically disposed on both sides of the lifting rod 63, the bottom of the clamping rod 65 is movably abutting against the inclined surface 64, a crossbar 66 is movably disposed through the center of the lifting rod 63, the crossbar 66 is fixedly connected to the inside of the fixed frame 61, and clamping wheels 67 are provided on the top of the lifting rod 63 and the top of the clamping rod 65.The part to be processed is placed on the placement ring 8 and kept stable. Initially, the two clamping rods 65 are separated from each other, the part is located in the middle of the clamping rods 65, and the lifting rod 63 is located at the lower end of the part. The lifting rod 63 is moved upward along the fixed block 62. The movement of the lifting rod 63 causes the inclined planes 64 on both sides to move upward along the fixed frame 61. Since the inclined planes 64 abut against the bottom of the clamping rods 65, the rise of the inclined planes 64 will cause the clamping rods 65 to rotate around the crossbar 66. The top of the clamping rods 65 will cause the clamping wheels 67 to move in a direction closer to each other until the clamping wheels 67 separate. Do not allow the lifting rod 63 to contact the lower side of the part. At this time, the clamping wheel 67 at the upper end of the lifting rod 63 also contacts the lower side of the part. The lifting rod 63 and the clamping wheel 67 of the clamping rod 65 clamp and limit the rod-shaped part. After the limit is completed, the part can be clamped and fixed by keeping the position of the lifting rod 63 unchanged. The rotation angle of the clamping rod 65 is related to the rising height of the lifting rod 63. When the diameter of the part is different, for example, the diameter of the part this time is smaller than that of the part last time, but when the clamping assembly 6 is used to clamp the part this time, because the diameter of the part has become smaller, when the lifting rod 63 moves upward until the clamping wheel 67 contacts the lower side of the part... When the parts come into contact, the clamping wheel 67 on the clamping rod 65 has not yet made contact with the side of the part, so the part is not clamped and fixed at this time. If the lifting rod 63 continues to move upward, the upward movement of the lifting rod 63 will drive the clamping rod 65 to continue rotating closer to each other. However, the lifting rod 63 will push the part, thus failing to ensure the balance of the part. Therefore, even if the clamping rod 65 comes into contact with the part, the stability of the clamping cannot be guaranteed. Therefore, when the diameter of the part changes, the height of the placement ring 8 needs to be changed to ensure that the center of the part always remains at the same height. When the diameter of the part decreases, the center of the part relative to the previous part center is... Slightly downwards, the placement ring 8 needs to be moved upwards along the vertical plate 5 to move the part upwards, so that the center of the part is level with the previous center height. At this time, the clamping assembly 6 can still firmly clamp the part because the rising height of the lifting rod 63 has increased, and the rotation angle of the clamping rod 65 has also increased. Moving the part upwards can prevent the lifting rod 63 from contacting the bottom of the part before the clamping wheel 67 of the clamping rod 65 contacts the part, which would cause the part to be pushed and result in poor fixation. In this step, the coordination of the height of the clamping assembly 6 and the placement ring 8 can clamp and limit rod-shaped parts of different diameters.

[0031] See Figure 3 and Figure 5In this embodiment, preferably, the bottom of the lifting rod 63 movably passes through the fixed frame 61 and is internally threadedly connected to a rotating rod 9. The end of the rotating rod 9 away from the lifting rod 63 is fixedly connected to a first gear 10. When the first gear 10 is rotated, the rotation of the first gear 10 causes the rotating rod 9 to rotate. Since the rotating rod 9 and the lifting rod 63 are threadedly connected, the rotation of the rotating rod 9 will cause the lifting rod 63 to move upward, thereby causing the clamping rod 65 to clamp the part. In this step, the lifting rod 63 can be raised and lowered by rotating the rotating rod 9 to ensure the stability of the lifting rod 63, because the lifting rod 63 will not move when the first gear 10 remains stationary.

[0032] See Figure 2-3 As shown, in this embodiment, preferably, a movable plate 11 is provided on one side of the first gear 10. The movable plate 11 is connected to the cleaning component 4. A horizontal plate 12 is fixedly provided on the side of the movable plate 11 near the first gear 10. A first rack 13 is provided on the end of the horizontal plate 12 away from the movable plate 11. The first rack 13 meshes with the first gear 10 for transmission. Moving the movable plate 11 causes the horizontal plate 12 and the first rack 13 to move. During the movement of the first rack 13, it will mesh with the first gears 10 of the two sets of clamping components 6 in sequence, thereby driving the two first gears 10 to rotate. This enables the two sets of clamping components 6 to work and clamp and limit the parts. The number of teeth of the first rack 10 can be increased or decreased to adjust the rising height of the lifting rod 63, so as to adapt to parts of different diameters. In this step, the movement of the movable plate 11 can drive the two sets of clamping components 6 to clamp and limit the parts, making the operation more convenient and faster.

[0033] See Figure 2 and Figure 6In this embodiment, preferably, a groove 51 is provided on one side of the vertical plate 5, and the horizontal plate 12 is slidably connected to the groove 51. The vertical plate 5 is vertically provided with a moving groove 52, and the placement ring 8 is slidably connected to the moving groove 52. A round rod 14 is threadedly connected to the bottom of the placement ring 8. The round rod 14 moves through the vertical plate 5 and its end is placed in the groove 51. A second gear 15 is fixedly provided at the end of the round rod 14, and the second gear 15 meshes with the first rack 13 for transmission. There are two vertical plates 5 and two clamping components 6. In the initial state, the part is placed on the two placement rings 8 and kept stable. At this time, there is contact between the part and the placement rings 8, and it is inconvenient for the cleaning component 4 to clean it. Moving the moving plate 11 causes the horizontal plate 12 to move, so that the first rack 13 meshes with the first gear 10, which drives the first set of clamping components 6 to work. The first clamping component 6 fixes one end of the part. Continuing to move the moving plate 11, the moving plate 11 drives the horizontal plate 12 and the first rack. 13 passes through the groove 51 of the vertical plate 5 to engage with the second gear 15. The second gear 15 rotates and drives the round rod 14 to rotate. Since the round rod 14 is threadedly connected to the lifting rod 63, the rotation of the round rod 14 will cause the placement ring 8 to move downward so that the placement ring 8 is no longer in contact with the part. The moving plate 11 continues to move, and the moving plate 11 will drive the horizontal plate 12 and the first rack 13 to engage with another set of first gears 10, so that the clamping assembly 6 clamps the part. At this time, the part can remain stable. Finally, the moving plate 11 is moved again, and the moving plate 11 drives the horizontal plate 12 and the first rack 13 to engage with another set of second gears 15, causing the placement ring 8 on this side to move downward and release the contact state with the part. In this step, the movement of the horizontal plate 12 and the first rack 13 can sequentially drive the two sets of clamping assemblies 6 to work and the two placement rings 8 to release the contact state with the part. The stability of the part can also be guaranteed during this process. This makes it convenient to clean the part and also to clamp and limit the part, which is convenient for subsequent processing operations.

[0034] See Figure 7As shown, in this embodiment, preferably, the cleaning component 4 includes a movable block 41, a slot 411 is provided in the movable block 41, a square block 42 is movably disposed in the slot 411, and a cleaning ring 43 is provided at the bottom of the square block 42. The movable block 41 is fixedly connected to the movable plate 11. When the motor of the movable block 41 is started, the movable block 41 moves along the fixed rod 3. The movement of the movable block 41 drives the movable plate 11 to move, thereby clamping the part. The movement of the movable block 41 will drive the square block 42 and the cleaning ring 43 to move, and the cleaning ring 43 will wrap the part inside. The cleaning ring 43 can be moved and filled with some elastic wiping cotton to facilitate wiping and cleaning of parts of different diameters. Because the diameters of the parts are different, the height of the placement ring 8 will be adjusted accordingly to facilitate the clamping component 6 to hold the parts firmly. Therefore, after the height of the placement ring 8 and the parts are adjusted, the height of the cleaning ring 43 also needs to be adjusted accordingly to facilitate the cleaning of the outer surface of the parts during the movement of the cleaning ring 43. Therefore, the square block 42 can be moved up and down along the slot 411 to adjust the height of the cleaning ring 43 to adapt to the cleaning of the parts.

[0035] See Figure 8 As shown, in this embodiment, preferably, the side plate of the movable block 41 is provided with a plurality of limiting holes 412, and the square block 42 is provided with a receiving groove 421 on the side near the limiting holes 412. A limiting ball 16 is provided in the receiving groove 421, and the limiting ball 16 is movably engaged with the limiting hole 412. When it is necessary to adjust the height of the cleaning ring 43, the square block 42 is moved up or down along the groove 411. The limiting ball 16 is provided in the receiving groove 421 of the square block 42. The limiting ball 16 is made of an elastic material. When the limiting ball 16 moves with the square block 42 in the movable block 41, the limiting ball 16 will be in a compressed state due to the abutment of the inner wall of the square block 42. When it moves to the position of the limiting hole 412, the limiting ball 16 will be engaged with the limiting hole 412 due to the loss of the abutment, so that the square block 42 cannot move again. This allows the height of the cleaning ring 43 to be adjusted.

[0036] See Figure 9As shown, in this embodiment, preferably, a fixing ring 17 is fixedly provided at the center of the limiting hole 412, and a push rod 18 is movably provided through the center of the fixing ring 17. A spring 19 is provided between the push rod 18 and the fixing ring 17. When the limiting ball 16 is engaged with the limiting hole 412, if it is necessary to readjust the height of the cleaning ring 43, it is necessary to release the engagement between the limiting ball 16 and the limiting hole 412, move the push rod 18 inward, and move the push rod 18 inward along the limiting hole 412 to push the limiting ball 16 out of the limiting hole 412, thereby releasing the engagement between the limiting ball 16 and the limiting hole 412. During this process, the spring 19 is in a compressed state. At this time, the square block 42 is moved to readjust the height of the cleaning ring 43. At this time, the force applied to the push rod 18 is removed, and the spring 19 returns to its original state, driving the push rod 18 back to its original position. The fixing ring 17 provides support for the spring 19.

[0037] See Figures 10-11 As shown, in this embodiment, preferably, the dust collection assembly 7 includes a fixed box 71, with a support rod 72 fixedly connected between the fixed box 71 and the base plate 1. A first dust collection box 73 and a second dust collection box 74 are axially symmetrically arranged on both sides above the fixed box 71. The first dust collection box 73 is located above the second dust collection box 74. A deflection rod 75 is rotatably arranged between each pair of the fixed box 71, the first dust collection box 73, and the second dust collection box 74. A rotating plate 76 is movably arranged between the second dust collection box 74 and the fixed box 71. The two rotating plates 76 mesh and drive each other. A rotating shaft 20 is provided on the upper part, and the rotating shaft 20 is fixedly connected to the rotating plate 76. When the rotating shaft 20 is rotated, the rotation of the rotating shaft 20 drives the rotating plate 76 on one side to rotate. The rotation of one rotating plate 76 drives the other rotating plate 76 to rotate as well. The rotation of the rotating plate 76 drives the deflection rod 75 to rotate, thereby causing the first dust collection box 73 and the second dust collection box 74 to be stacked and unfolded to both sides. The first dust collection box 73, the second dust collection box 74 and the fixed box 71 are all designed in a vacuum state, which can catch the debris generated by the processing of parts. The support rod 72 provides support for the fixed box 71.

[0038] See Figure 2-3 and Figure 10As shown, in this embodiment, preferably, a third gear 21 is fixedly installed at the end of the rotating shaft 20 away from the rotating plate 76, and a second rack 22 is fixedly installed above the horizontal plate 12. The second rack 22 meshes with the third gear 21 for transmission. The movement of the moving block 41 causes the moving plate 11, the horizontal plate 12 and the second rack 22 to move. During the movement, the second rack 22 will mesh with the third gear 21, thereby driving the third gear 21 to rotate. The rotation of the third gear 21 drives the rotating shaft 20 to rotate, thereby causing the first dust collection box 73 and the second dust collection box 74 to unfold, so as to catch the debris generated by the processing of the parts.

[0039] The working principle of this invention is as follows: The rod-shaped part to be processed is placed on the placement ring 8 of the vertical plate 5. The motor of the moving block 41 is started, and the moving block 41 moves along the fixed rod 3. The movement of the moving block 41 drives the moving plate 11 to move. The movement of the moving plate 11 drives the horizontal plate 12 to move, so that the first rack 13 meshes with the first gear 10, driving the first clamping assembly 6 to work. The first clamping assembly 6 fixes one end of the part. The moving plate 11 continues to move, and the moving plate 11 drives the horizontal plate 12 and the first rack 13 to pass through the groove 51 opened in the vertical plate 5, thereby meshing with the second gear 15. The second gear 15 then rotates, which can drive the round rod 14 to rotate. Since the round rod 14 is threadedly connected to the lifting rod 63, the round rod... The rotation of 14 causes the placement ring 8 to move downwards, so that the placement ring 8 is no longer in contact with the part. Continuing to move the moving plate 11, the moving plate 11 will drive the horizontal plate 12 and the first rack 13 to mesh with the first gear 10 of another set, so that the clamping assembly 6 clamps the part. At this time, the part can remain stable. Finally, the moving plate 11 is moved again. The moving plate 11 drives the horizontal plate 12 and the first rack 13 to mesh with another second gear 15, causing the placement ring 8 on this side to move downwards and release from contact with the part. During this process, the cleaning ring 43 cleans the outer surface of the part simultaneously. The working principle of the clamping assembly 6 is that the lifting rod 63 moves upwards along the fixed block 62. The movement of the lifting rod 63 causes the inclined surfaces 64 on both sides to move upwards along the fixed frame 61. As the inclined plane 64 abuts against the bottom of the clamping rod 65, the upward movement of the inclined plane 64 causes the clamping rod 65 to rotate around the crossbar 66. The top of the clamping rod 65 causes the clamping wheels 67 to move closer together until the clamping wheels 67 abut against both sides of the part. At this time, the clamping wheels 67 at the upper end of the lifting rod 63 also abut against the lower side of the part. The lifting rod 63 and the clamping wheels 67 of the clamping rod 65 clamp and limit the rod-shaped part. After the limit is completed, the part can be clamped and fixed by keeping the position of the lifting rod 63 unchanged. The rotation angle of the clamping rod 65 is related to the rising height of the lifting rod 63. When the diameter of the part is different, for example, the diameter of the part in this case is smaller than that of the part in the previous case, but the clamping assembly 6 is used to clamp the part, the clamping rod 65 will be able to rotate. When clamping the part, because the part diameter has decreased, when the lifting rod 63 moves upward until the clamping wheel 67 abuts against the bottom of the part, the clamping wheel 67 on the clamping rod 65 has not yet contacted the side of the part. At this time, the part is not clamped and fixed. If the lifting rod 63 continues to move upward, the upward movement of the lifting rod 63 will drive the clamping rod 65 to continue rotating closer to each other. However, the lifting rod 63 will push the part, thus failing to ensure the balance of the part. In this way, even if the clamping rod 65 abuts against the part, the clamping stability cannot be guaranteed. Therefore, when the diameter of the part changes, the height of the placement ring 8 needs to be changed to ensure that the center of the part always remains at the same height. When the diameter of the part decreases, the center of the part is lower than the previous part center.The ring 8 needs to be moved upwards along the vertical plate 5 to move the part upwards, so that the center of the part is at the same height as the previous center. At this time, the clamping assembly 6 can still firmly clamp the part because the lifting rod 63 has increased in height and the rotation angle of the clamping rod 65 has also increased. Moving the part upwards can prevent the lifting rod 63 from contacting the bottom of the part before the clamping wheel 67 of the clamping rod 65 contacts the part, which would cause the part to be pushed and result in poor fixation. At the same time, the movement of the moving block 41 causes the moving plate 11, the horizontal plate 12 and the second rack 22 to move. During the movement, the second rack 22 will mesh with the third gear 21, thereby driving the third gear 21 to rotate. The rotation of the third gear 21 drives the rotating shaft 20 to rotate, thereby causing the first dust collection box 73 and the second dust collection box 74 to unfold, making it easier to catch the debris generated by the part processing.
