Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile manufacturing technology, specifically to a cutting and feeding fixture for automobile steering wheel roller levers. Background Technology
[0002] A type of automotive function button uses a polyhedral prism as a steering wheel scroll lever, as shown in the reference. Figure 8 The polyhedral prism is molded into eight pieces in one batch in the injection mold of the molding machine. Each pair of pieces forms a group, and each group shares a set of gate runners. Therefore, the structure of the injection molded part taken out of the molding machine is that a material handle 81 carries two lever bodies 82 through the sprue 8. The clamps on the cutting equipment used in the prior art can only clamp one lever body 82 at a time. After the cutting equipment cuts off the sprue 8 on the lever body 82, the cut lever body 82 is taken out. Then, the other lever body 82 is clamped and fixed by the clamp, and the sprue 8 on the other lever body 82 is cut off. The cutting equipment can only cut one lever body 82 at a time, which is inefficient. At the same time, after the cutting equipment cuts off the sprue 8 on the lever body 82, the lever body 82 is inserted into the inside of the clamp. The worker needs to manually pull the lever body 82 out of the clamp. The process of manually pulling out the lever body 82 consumes a lot of time and reduces the efficiency of the worker to repeatedly clamp and fix the lever body 82 using the clamp. Utility Model Content
[0003] The purpose of this invention is to provide a cutting and feeding fixture for automotive steering wheel roller levers, in order to solve the problems mentioned in the background art.
[0004] 1. The existing clamps on the cutting equipment can only clamp one lever body at a time, which means that the cutting equipment can only cut one lever body at a time, resulting in low cutting efficiency.
[0005] 2. After the cutting equipment cuts the sprue off the lever body, the lever body is inserted into the inside of the clamp. The worker needs to manually pull the lever body out of the clamp, which is inconvenient.
[0006] To achieve the above objectives, this utility model provides a cutting and feeding fixture for automotive steering wheel roller levers, including a processing table. A housing is disposed above the processing table. A first displacement component for driving the housing to move horizontally longitudinally is disposed on the upper side of the processing table near its edge. A clamping mechanism is disposed on one side of the housing. A second displacement component for driving the clamping mechanism to move horizontally laterally is disposed inside the housing. The clamping mechanism includes an assembly plate. A cylinder is fixedly mounted on the side of the assembly plate away from the second displacement component. An n-shaped moving block is fixedly disposed at the lower end of the cylinder piston rod. A slider is slidably disposed inside the moving block. A component fixed to the assembly plate is disposed directly below the slider. The mounting plate has a fixed block with two lower arc-shaped grooves on its upper sidewall and the side of the slider that are close to each other. The upper sidewall of the slider and the top side of the moving block have two upper arc-shaped grooves at corresponding positions. The mounting plate is equipped with two pushing components. When the second displacement component drives the clamping mechanism to approach the first displacement component, the pushing component pushes the lever body inside the upper and lower arc-shaped grooves away from the housing. The clamping mechanism can clamp and fix four lever bodies at the same time, so that the cutting equipment can cut four lever bodies at one time, improving the cutting efficiency. The pushing component is used to push the lever body after the sprue is cut out from inside the clamping mechanism, improving the unloading efficiency of the lever body.
[0007] As a further improvement to this technical solution, when the piston rod of the cylinder drives the moving block to approach the fixed block, every two corresponding upper arc grooves and every two corresponding lower arc grooves cooperate to clamp and fix the lever body. Every two corresponding upper arc grooves and every two corresponding lower arc grooves form a circular cavity, which can clamp and fix the lever body inserted inside it.
[0008] As a further improvement to this technical solution, the assembly plate has an installation groove on the side near the housing. The pusher assembly includes an end plate vertically installed inside the installation groove. Two push rods are fixedly installed on the side of the end plate away from the housing. The other ends of the two push rods slide through one side of the assembly plate and extend into one of the lower arc grooves and one of the upper arc grooves on the slider, respectively. The push rods restrict the end plate to move only along the axis of the push rods, ensuring that the end plate can drive the push rods to move inside the circular cavity.
[0009] As a further improvement to this technical solution, a shielding cover is fixedly provided on the side of the housing near the clamping mechanism, and two guide plates are fixedly provided on the other side of the shielding cover. The two guide plates are provided with a first horizontal groove, an oblique groove and a second horizontal groove on the side close to each other. The first horizontal groove, the oblique groove and the second horizontal groove form a Z-shaped groove. The distance between the second horizontal groove and the housing is greater than the distance between the first horizontal groove and the housing. The shielding cover is used to prevent dust and impurities from entering the interior of the housing and adhering to the second lead screw, ensuring the normal use of the second lead screw. The shielding cover also provides an installation position for the guide plates.
[0010] As a further improvement to this technical solution, the pusher assembly also includes two cylinders that are respectively fixedly mounted on the side wall and the lower side wall of the end plate. The two cylinders are slidably mounted inside the two Z-shaped grooves. When the cylinder slides in the inclined groove toward the direction of the second transverse groove, the push rod moves away from the housing, so that the push rod pushes the lever body out of the lower arc groove or the upper arc groove, that is, the push rod pushes the lever body out of the circular cavity.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This automotive steering wheel roller lever cutting and feeding fixture, after the fixture releases the clamping and fixing of the lever body, the second displacement component drives the clamping mechanism and the pushing component to move laterally horizontally, so that the cylinder slides from the inside of the first horizontal groove to the inside of the second horizontal groove. During this process, the cylinder drives the end plate, push rod and ejector rod to move synchronously, so that the push rod pushes the lever body out of the circular cavity, and the ejector rod pushes the material handle out of the receiving groove, thereby realizing the rapid separation of the lever body and the material handle from the clamping mechanism, improving the efficiency of workers using this fixture to clamp and fix new injection molded parts.
[0013] 2. The fixture is equipped with a circular cavity consisting of two corresponding upper arc-shaped grooves and two corresponding lower arc-shaped grooves. The worker inserts each lever body into the corresponding circular cavity, and then the piston rod of the cylinder drives the moving block and the slider to approach the fixed block. This allows each pair of corresponding upper arc-shaped grooves and each pair of corresponding lower arc-shaped grooves to clamp and fix the lever body, thus fixing the two injection molded parts on the clamping mechanism. This allows the cutting equipment to cut the sprue on the four lever bodies at once, improving the cutting efficiency of the cutting equipment for sprue. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Example 1
[0033] Please see Figure 1 , Figure 2 and Figure 8 As shown, one of the objectives of this embodiment is to provide a cutting and feeding fixture for automotive steering wheel roller levers, including a processing table 1, a housing 2 disposed above the processing table 1, and a clamping mechanism 3 disposed on one side of the housing 2. The clamping mechanism 3 is used to clamp and fix the lever body 82. By clamping and fixing the lever body 82 through the clamping mechanism 3, the injection molded part composed of the sprue 8, the material handle 81 and the two lever bodies 82 can be fixed on the side of the clamping mechanism 3 away from the housing 2. A first displacement component 4 is disposed on the upper side of the processing table 1 near the edge to drive the housing 2 to move longitudinally and horizontally. At the same time, inside the housing 2... A second displacement component 5 is provided to drive the clamping mechanism 3 to move horizontally. The second displacement component 5 and the first displacement component 4 cooperate to adjust the position of the clamping mechanism 3 above the processing table 1. When this fixture is used, it is installed on one side of the cutting equipment. The saw blade of the cutting equipment is located above the processing table 1. After the worker uses the clamping mechanism 3 to fix the injection molded part on the side of the clamping mechanism 3 away from the housing 2, the position of the clamping mechanism 3 and the injection molded part can be adjusted by the cooperation of the second displacement component 5 and the first displacement component 4. The injection molded part can then be moved to the cutting position of the saw blade for cutting, so that the cutting equipment can cut and separate the sprue 8 from the lever body 82.
[0034] The structure of the first displacement component 4 is described in detail below, referring to... Figure 3 The first displacement component 4 includes an assembly box 41 longitudinally fixedly mounted on the upper side wall of the processing table 1. A first lead screw 42 is horizontally rotatably mounted inside the assembly box 41. A first servo motor is fixedly mounted on one side of the assembly box 41, and the output shaft of the first servo motor is coaxially fixed to the first lead screw 42 via a coupling. A first slide 43, threadedly connected to the first lead screw 42, is slidably mounted inside the assembly box 41. The upper side wall of the first slide 43 is fixedly mounted on the lower side wall of the housing 2 near one side, and a guide block 21 is fixedly mounted on the lower side wall of the housing 2 near the other side. A guide rail 11 is fixedly mounted on the upper side wall of the processing table 1. The guide block 21 is slidably disposed inside the guide rail 11. The direction in which the guide block 21 slides inside the guide rail 11 is parallel to the axial direction of the first lead screw 42. When the output shaft of the first servo motor drives the first lead screw 42 to rotate, the assembly box 41 restricts the position of the first slide 43 in the assembly box 41. Through the threaded connection between the first lead screw 42 and the first slide 43, the first slide 43 moves along the axial direction of the first lead screw 42. That is, the first slide 43 is driven by the first lead screw 42 to slide inside the assembly box 41. The moving first slide 43 drives the housing 2 and the guide block 21 to move synchronously, thereby driving the housing 2 to move in the longitudinal horizontal direction on the processing table 1.
[0035] The structure of the second displacement component 5 is detailed below, referring to... Figure 4 The second displacement component 5 includes a second lead screw 51 that is laterally and horizontally rotatable inside the housing 2. A second servo motor is fixedly mounted on one side of the housing 2. The output shaft of the second servo motor is coaxially fixed to one end of the second lead screw 51 via a coupling. A second slide 52, threadedly connected to the second lead screw 51, is slidably disposed inside the housing 2. A clamping mechanism 3 is disposed on one side of the second slide 52. When the output shaft of the second servo motor drives the second lead screw 51 to rotate, the housing 2 restricts the position of the second slide 52 inside the housing 2. Through the threaded connection between the second slide 52 and the second lead screw 51, the second slide 52 moves along the axial direction of the second lead screw 51. That is, the second slide 52 is driven by the second lead screw 51 to slide inside the housing 2. The moving second slide 52 drives the clamping mechanism 3 to move, thereby adjusting the position of the clamping mechanism 3 laterally and horizontally.
[0036] After the clamping mechanism 3 clamps and fixes the two injection molded parts, the positions of the clamping mechanism 3 and the two injection molded parts can be adjusted in the horizontal direction by the first displacement component 4 and the second displacement component 5. That is, the first displacement component 4 and the second displacement component 5 can drive the clamping mechanism 3 to move on the processing table 1, so that the clamping mechanism 3 can move to any point on the processing table 1 within the movement range of the first displacement component 4 and the second displacement component 5.
[0037] The structure of clamping mechanism 3 is described in detail below, with reference to... Figure 5 and Figure 6 The clamping mechanism 3 includes an assembly plate 31, which is fixedly mounted on the second slide table 52 by bolts. A cylinder 32 is fixedly mounted on the side of the assembly plate 31 away from the second displacement component 5. The cylinder 32 is mounted near the top of the assembly plate 31. An n-shaped moving block 33 is fixedly mounted on the lower end of the piston rod of the cylinder 32. A slider 34 is slidably mounted inside the moving block 33. The side of the slider 34 away from the housing 2 is in slidable contact with a stop bar 39 fixed inside the moving block 33. The stop bar 39 prevents the slider 34 from moving away from the housing 2. At the same time, protrusions fixed on the slider 34 are provided above and below the stop bar 39. The distance between the two protrusions at one end of the stop bar 39 is greater than the height of the stop bar 39. That is, one end of the stop bar 39 can only contact the side wall of one of the protrusions. The protrusions restrict the vertical sliding path of the slider 34 inside the moving block 33. At the same time, the block bar 39 prevents the slider 34 from moving out of the moving block 33 by blocking the protrusions.
[0038] Simultaneously, a fixing block 35 fixed to the assembly plate 31 is provided directly below the slider 34. Two lower arc-shaped grooves 36 are formed on the upper sidewall of the fixing block 35 and the side of the slider 34 that are close to each other, resulting in a total of four lower arc-shaped grooves 36. Two upper arc-shaped grooves 38 are formed on the upper sidewall of the slider 34 and the corresponding top side inside the moving block 33, resulting in a total of four upper arc-shaped grooves 38. Two corresponding lower arc-shaped grooves 36 and two corresponding upper arc-shaped grooves 38 each form a circular cavity. A total of four such circular cavities are provided. When the slider 34 is not in contact with the fixing block 35, a lever body 82 can be inserted into the interior of each circular cavity. The maximum vertical spacing between the cavities is greater than the outer diameter of the lever body 82. Each injection molded part is provided with two lever bodies 82. By inserting each lever body 82 into the corresponding circular cavity, two injection molded parts can be pre-fixed in the clamping mechanism 3. At the same time, two storage slots 37 are opened on the slider 34. The storage slots 37 are located below the stop bar 39, and a notch corresponding to the storage slot 37 is opened on the lower side of the stop bar 39. The notch and the upper half of the storage slot 37 have the same shape. When the injection molded part is inserted into the clamping mechanism 3, the material handle 81 in the injection molded part is inserted into the corresponding storage slot 37, thereby ensuring that the worker can smoothly insert the lever body 82 into the corresponding circular cavity.
[0039] When the piston rod of cylinder 32 drives the moving block 33 to approach the fixed block 35, the moving block 33 drives the slider 34 to simultaneously approach the fixed block 35. After the moving slider 34 contacts the fixed block 35, the distance between the two corresponding lower arc-shaped grooves 36 reaches its minimum, and the space of the circular cavity formed by the two corresponding lower arc-shaped grooves 36 reaches its minimum. At this time, the circular cavity formed by the two corresponding lower arc-shaped grooves 36 can clamp and fix the lever body 82 inserted inside it. When the slider 34 contacts the fixed block 35, if the moving block 33 drives the slider 34 to approach the fixed block 35, the moving block 33 will move the slider 34 to approach the fixed block 35. 4. As the slider moves closer to the fixed block 35, the fixed block 35 pushes the slider 34 upward inside the moving block 33, reducing the distance between the upper end of the slider 34 and the inner top of the moving block 33. At this time, the distance between the two corresponding upper arc grooves 38 decreases, and the two corresponding upper arc grooves 38 can clamp and fix the lever body 82 inserted inside them. At the same time, the storage groove 37 will move synchronously with the slider 34, and the vertical distance between the storage groove 37 and the stop bar 39 will decrease. The stop bar 39 cooperates with the inner wall of the storage groove 37 to clamp and fix the material handle 81.
[0040] In summary, after the worker inserts and pre-fixes the four lever bodies 82 on the two injection molded parts into the four circular cavities, the piston rod of the cylinder 32 drives the moving block 33 to approach the fixed block 35. This allows each pair of corresponding upper arc grooves 38 and each pair of corresponding lower arc grooves 36 to clamp and fix the lever body 82, and the receiving groove 37 to clamp and fix the material handle 81 with the stop strip 39, thus fixing the two injection molded parts on the clamping mechanism 3.
[0041] After the cutting equipment separates the sprue 8 from the lever body 82, the four lever bodies 82 are fixed in their respective circular cavities, and the two material handles 81 are inserted into their respective storage slots 37. The piston rod of the cylinder 32 retracts, causing the moving block 33 and the slider 34 to move away from the fixed block 35, thereby releasing the clamping mechanism 3 from the lever body 82. Then, the worker pulls out the four lever bodies 82 one by one from their respective circular cavities and pulls out the two material handles 81 from their respective storage slots 37, thus completing the cutting of the lever body 82.
[0042] After the lever body 82 is removed, two new injection molded parts are inserted into the clamping mechanism 3. The clamping mechanism clamps and feeds the two new injection molded parts. However, during the removal of the lever body 82, the worker needs to manually pull out the lever body 82 and the material handle 81. This process consumes a lot of the worker's time and reduces the efficiency of the worker using the clamping mechanism to fix the new injection molded parts. To solve this problem, two pusher components 6 are provided on the assembly plate 31. When the second displacement component 5 drives the clamping mechanism 3 to approach the first displacement component 4, the pusher component 6 pushes the lever body 82 inside the upper arc groove 38 and the lower arc groove 36 away from the housing 2 until the lever body 82 is pushed out of the corresponding circular cavity. At the same time, the pusher component 6 also pushes the material handle 81 out of the corresponding storage groove 37, realizing the quick separation of the lever body 82 and the material handle 81 from the clamping mechanism 3, and improving the efficiency of the worker using the clamping mechanism to fix the new injection molded parts.
[0043] A mounting groove 311 is provided on the side of the assembly plate 31 near the housing 2. The structure of the pusher assembly 6 is described in detail below, referring to... Figure 7The pushing assembly 6 includes an end plate 61 vertically disposed inside the mounting groove 311. Two push rods 62 are fixedly disposed on the side of the end plate 61 away from the housing 2. The other ends of the two push rods 62 slide through one side of the mounting plate 31 and extend into one of the lower arc grooves 36 and one of the upper arc grooves 38 on the slider 34, respectively. At the same time, an ejector rod is fixedly disposed on the end plate 61 at a position corresponding to the receiving groove 37. The other end of the ejector rod slides through the mounting plate 31 and extends into the corresponding receiving groove 37. Meanwhile, a shielding cover 22 is fixedly disposed on the side of the housing 2 near the clamping mechanism 3. The shielding cover 22 is larger than the housing 2. Both the upper and lower sides of the shielding cover 22 protrude outward. Gaps are left between the upper and lower side walls of the shielding cover 22 and the housing 2. The second slide table 52 is slidably disposed inside the two gaps near both ends. The shielding cover 22 can prevent dust and impurities from entering the housing. The body 2 is adhered to the second lead screw 51 to ensure the normal use of the second lead screw 51. Two guide plates 7 are fixedly installed on the other side of the cover 22. The two guide plates 7 are provided with a first horizontal groove 71, an oblique groove 72 and a second horizontal groove 73 on the side close to each other. The first horizontal groove 71, the oblique groove 72 and the second horizontal groove 73 form a Z-shaped groove. The distance between the second horizontal groove 73 and the housing 2 is greater than the distance between the first horizontal groove 71 and the housing 2. The first horizontal groove 71 passes through the inside of the mounting groove 311. The second horizontal groove 73 is closer to the first displacement component 4 than the first horizontal groove 71. At the same time, the vertical distance between the first horizontal groove 71 and the second horizontal groove 73 is greater than the distance from the push rod 62 to the other end of the lower arc groove 36 or the upper arc groove 38. The push component 6 also includes two cylinders 63 that are fixedly installed on the upper side wall and the lower side wall of the end plate 61, respectively. The two cylinders 63 are slidably installed inside the two Z-shaped grooves.
[0044] When the clamping mechanism 3 clamps and fixes the lever body 82, the cylinder 63 is located inside the first transverse groove 71, and the distance between the push rod 62 and the ejector rod and the housing 2 is at its minimum. When the cutting device cuts and separates the sprue 8 from the lever body 82, after the clamping mechanism 3 releases its clamping and fixing of the lever body 82, the second displacement component 5 drives the clamping mechanism 3 and the push component 6 to move horizontally. When the cylinder 63 first slides from inside the first transverse groove 71 to inside the inclined groove 72, and then slides from inside the inclined groove 72 towards the second transverse groove 73, the inclined groove 72 pushes the cylinder 63 away from the housing 2. The moving cylinder 63 drives the end plate 61, the push rod 62 and the ejector rod to move together. The push rod 62 and the ejector rod move away from the housing 2. Since the vertical distance between the first transverse groove 71 and the second transverse groove 73 is greater than the distance from the push rod 62 to the other end of the lower arc groove 36 or the upper arc groove 38, when the cylinder 63 slides into the interior of the second transverse groove 73, the push rod 62 pushes the lever body 82 out of the lower arc groove 36 or the upper arc groove 38. That is, the moving push rod 62 pushes the lever body 82 out of the circular cavity. The end of the push rod 62 away from the end plate 61 extends out of the circular cavity. The moving ejector rod pushes the material handle 81 out of the storage groove 37, thereby realizing the rapid disengagement of the lever body 82 and the material handle 81 from the clamping mechanism 3.
[0045] When using this fixture, the worker first inserts and pre-fixes two injection molded parts onto the clamping mechanism 3. The clamping mechanism 3 clamps and fixes the two injection molded parts. Then, the first displacement component 4 and the second displacement component 5 adjust the position of the clamping mechanism 3 and the two injection molded parts, so that the external cutting device cuts the sprue 8 off the material handle 81 and the lever body 82. After that, the worker releases the clamping mechanism 3 from the material handle 81 and the lever body 82, and controls the second displacement component 5 to drive the clamping mechanism 3 and the push component 6 to move closer to the first displacement component 4. During this process, the cylinder 63 slides from the inside of the first transverse groove 71 to the inside of the second transverse groove 73. The moving cylinder 63 drives the end plate 61, the push rod 62 and the ejector rod to move synchronously, so that the push rod 62 pushes the lever body 82 out of the circular cavity, and the ejector rod pushes the material handle 81 out of the receiving groove 37, thereby realizing the rapid disengagement of the lever body 82 and the material handle 81 from the clamping mechanism 3.
