Description

Technical Field

[0001] This utility model relates to the field of fastener processing equipment technology, specifically to a bolt fixing device for a bolt stamping equipment. Background Technology

[0002] In the mass production of bolts, the stamping process is the core step that determines the structural strength and dimensional accuracy of the bolts. Because stamping requires applying significant pressure to the bolts, unstable bolt positioning can easily lead to displacement, resulting not only in bolt failure but also potential damage to the stamping die. Therefore, bolt fixing devices are crucial components of bolt stamping equipment. Their core purpose is to ensure the bolts maintain stable posture during stamping through precise clamping and positioning, while also adapting to the clamping requirements of bolts of different specifications, balancing processing accuracy and production efficiency.

[0003] According to a disclosed bolt fixing device for a bolt stamping equipment (Publication No.: CN118357368A), it includes: an operating table, a fixing plate fixedly connected to the front end of the upper surface of the operating table, a top plate fixedly connected to the top of the fixing plate, a hydraulic mechanism installed in the middle of the top plate, and mounting plates fixedly connected to the left and right sides of the middle of the upper surface of the operating table; a clamping mechanism, with a clamping mechanism installed at the upper end of one side of the two sets of mounting plates close to each other. Through the adjustment mechanism, the arc-shaped clamping sleeve can be adjusted up and down with the hydraulic mechanism during the stamping process, avoiding pressure from the hydraulic mechanism during clamping. Through the clamping sleeve fixing mechanism, the arc-shaped clamping sleeve can be quickly disassembled and replaced after damage. Through the lifting mechanism, the lifting plate and the lifting column are pushed upward, which facilitates the upward ejection of the stamped bolt without the need for manual separation of the bolt stamping die from the bolt.

[0004] In the above application, the adjustment mechanism adapts to the stroke of the hydraulic mechanism, the clamping sleeve fixing mechanism enables quick replacement, and the lifting mechanism replaces manual material handling, thus realizing the flexibility and maintenance convenience of bolt stamping clamping. However, the clamping relies on asymmetrical transmission, which can easily lead to uneven clamping forces on both sides. The bolt may still have a slight deviation under the action of stamping pressure, affecting the stamping dimension accuracy. Therefore, we propose a bolt fixing device for bolt stamping equipment. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a bolt fixing device for bolt stamping equipment, which solves the problems of poor bolt clamping synchronization and easy deviation, and lack of automatic lubrication and easy wear of transmission components in the prior art.

[0006] According to one aspect, at least one embodiment of the present invention provides a bolt fixing device for a bolt stamping equipment, comprising: an equipment housing, a support column fixedly connected to the top of the equipment housing, a stamping machine disposed on the top of the support column, and a clamping device disposed on the top of the equipment housing; The clamping device includes a motor bracket, the bottom of which is fixedly connected to the bottom of the inner wall of the equipment housing. A double-ended motor is fixedly connected to the inner circumferential surface of the motor bracket. A bevel gear is fixedly connected to the output shaft of the double-ended motor. A sliding groove is provided on the side of the support column. A driving block is slidably connected inside the sliding groove. A threaded sleeve is fixedly connected to the side of the driving block. A threaded rod is threadedly connected to the inner circumferential surface of the threaded sleeve. A bevel gear is fixedly connected to the bottom end of the threaded rod. A connecting rod is rotatably connected to the side of the driving block. A fixed clamp is rotatably connected to one end of the connecting rod.

[0007] For example, in a bolt fixing device of a bolt stamping equipment provided in at least one embodiment of the present invention, the device further includes: two fixing clamps are provided, which are symmetrical to each other along the vertical central axis of the equipment shell; the displacement trajectory of the drive block does not contact the top of the bevel gear; the two fixing clamps symmetrical along the vertical central axis can apply clamping force from both sides of the bolt simultaneously, so that the bolt is subjected to balanced force, and the bolt is prevented from shifting due to unilateral force during the stamping process, thus ensuring stamping accuracy. The top end of the threaded rod is rotatably connected to a rotating sleeve. The top of the rotating sleeve is fixedly connected to the top of the inner wall of the equipment housing. The rotating sleeve provides top support for the threaded rod, which can restrict the threaded rod to rotate only along its own axis, reduce the radial sway of the threaded rod during rotation, avoid jamming at the meshing point of the threaded sleeve and the threaded rod, and ensure the stability and accuracy of the up-and-down movement of the drive block. The first bevel gear and the second bevel gear mesh with each other. The diameter of the first bevel gear is equal to the diameter of the second bevel gear. The meshing of the first bevel gear and the second bevel gear can convert the horizontal rotational power of the double-ended motor into the vertical rotational power of the threaded rod, thus achieving precise matching of the power direction. The top of the device housing has a limiting groove, and the bottom of the fixing clamp is slidably connected inside the limiting groove. The limiting groove constrains the movement trajectory of the fixing clamp, limiting the fixing clamp to slide horizontally only along the direction of the limiting groove, thus preventing the fixing clamp from shifting laterally during clamping.

[0008] According to another aspect, at least one embodiment of the present invention also provides a bolt fixing device for a bolt stamping equipment, comprising: a lubrication device, the lubrication device including an oil tank, the bottom of the oil tank being fixedly connected to the bottom of the inner wall of the equipment housing, the top of the oil tank being fixedly connected to an oil supply pipe, one end of a double-ended motor being fixedly connected to a threaded rod II, the circumferential surface of the threaded rod II being threadedly connected to a threaded sleeve II, the side of the threaded sleeve II being fixedly connected to a moving plate, the side of the moving plate being fixedly connected to a transmission plate, the side of the transmission plate being fixedly connected to a pressing rod, and the circumferential surface of the pressing rod being slidably connected inside the oil tank.

[0009] For example, in a bolt fixing device for a bolt stamping equipment provided in at least one embodiment of the present invention, a slide rail is fixedly connected to the bottom of the inner wall of the equipment housing, and a smooth rod is fixedly connected to the side of the inner wall of the equipment housing. The slide rail provides a stable sliding support foundation for the moving plate, and the smooth rod can initially constrain the moving direction of the moving plate. The two work together to lay a structural foundation for the smooth sliding of the moving plate in the future and avoid the moving plate from tilting due to lack of support. The bottom of the movable plate is slidably connected to the top of the slide rail, and the circumferential surface of the smooth rod is slidably connected to the side of the movable plate. The sliding of the movable plate along the slide rail can greatly reduce the bottom friction resistance, making the movable plate respond more quickly to the drive of the threaded rod. The smooth rod passes through the movable plate and restricts its lateral displacement, ensuring that the movable plate always moves in a straight line, and avoiding meshing failure between the threaded sleeve and the threaded rod due to displacement. Two threaded sleeves, two threaded rods, and two oil delivery pipes are provided, and they are symmetrical to each other along the vertical central axis of the double-ended motor. One end of the oil delivery pipe is located at the top of the first bevel gear. The two symmetrical threaded sleeves and two threaded rods can synchronously drive the moving plates on both sides, so that the squeezing force of the extrusion rod on the oil tank is balanced, ensuring stable output of lubricating oil. One end of the oil delivery pipe is aligned with the top of the first bevel gear, which can accurately deliver lubricating oil to the meshing gap between the first and second bevel gears, avoiding gear wear due to insufficient lubrication. The displacement trajectory of the transmission plate does not contact the side of the oil tank, and the displacement trajectory of the moving plate does not contact the inner wall side of the equipment housing. The displacement trajectory of the transmission plate avoids the side of the oil tank, which can prevent the transmission plate from colliding with the oil tank during movement and causing deformation of the oil tank or damage to the transmission plate. The displacement trajectory of the moving plate avoids the inner wall side of the equipment housing, which can prevent the moving plate from rubbing against the housing wall and causing scratches or jamming, thus ensuring smooth movement of all components of the lubrication device.

[0010] The beneficial effects of the embodiments of this utility model are as follows: 1. In this utility model, a clamping device consisting of a double-ended motor, symmetrical bevel gears, double fixed clamps, and a limiting groove is used. The double-ended motor drives the threaded rod to rotate through the meshing transmission of the bevel gears, causing the threaded sleeve to drive the drive block to slide along the slide groove. Then, through the connecting rod, the two symmetrical fixed clamps are pushed to clamp the bolt synchronously along the limiting groove, realizing the balanced force on both sides of the bolt, effectively avoiding bolt deviation during stamping, and ensuring stamping accuracy. The support of the rotating sleeve for the threaded rod and the constraint of the limiting groove on the fixed clamps reduce transmission jamming and clamping deviation, improve the stability and response efficiency of the clamping action, and meet the precise fixing requirements of batch bolt stamping.

[0011] 2. In this utility model, the threaded rod is rotated synchronously by a double-ended motor, which causes the threaded sleeve to drive the moving plate to slide smoothly along the slide rail and the smooth rod. The moving plate pushes the extrusion rod to extrude the oil tank through the transmission plate. The lubricating oil is accurately delivered to the meshing gap of the bevel gear through symmetrical oil supply pipes. No additional lubrication drive components are required, which reduces the energy consumption and structural complexity of the equipment. The symmetrical oil supply pipes ensure sufficient lubrication of the bevel gears on both sides, reducing gear wear. Combined with the smooth sliding design of the moving plate, the lubrication device is prevented from jamming, which extends the overall service life of the clamping device and the lubrication device and reduces the equipment maintenance cost.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0016] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

[0020] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] like Figures 1-5 The present invention illustrates a bolt fixing device for a bolt stamping equipment in one embodiment of the present invention, comprising: an equipment housing 1, a support column 2 fixedly connected to the top of the equipment housing 1, a stamping machine 3 disposed on the top of the support column 2, and a clamping device 4 disposed on the top of the equipment housing 1. The clamping device 4 includes a motor bracket 41, the bottom of which is fixedly connected to the bottom of the inner wall of the equipment housing 1. A double-ended motor 42 is fixedly connected to the inner circumferential surface of the motor bracket 41. A bevel gear 43 is fixedly connected to the output shaft of the double-ended motor 42. A sliding groove 44 is provided on the side of the support column 2. A drive block 45 is slidably connected inside the sliding groove 44. A threaded sleeve 46 is fixedly connected to the side of the drive block 45. A threaded rod 47 is threadedly connected to the inner circumferential surface of the threaded sleeve 46. A bevel gear 48 is fixedly connected to the bottom end of the threaded rod 47. A connecting rod 49 is rotatably connected to the side of the drive block 45. A fixed clamp 410 is rotatably connected to one end of the connecting rod 49.

[0022] In some examples: there are two fixing clamps 410, which are symmetrical to each other along the vertical central axis of the equipment housing 1. The displacement trajectory of the drive block 45 does not contact the top of the bevel gear 48. The two fixing clamps 410, which are symmetrical along the vertical central axis, can apply clamping force from both sides of the bolt simultaneously, so that the bolt is subjected to balanced force, and avoids the bolt from shifting due to unilateral force during the stamping process, thus ensuring stamping accuracy.

[0023] A rotating sleeve 411 is rotatably connected to the top of the threaded rod 47. The top of the rotating sleeve 411 is fixedly connected to the top of the inner wall of the equipment housing 1. The rotating sleeve 411 provides top support for the threaded rod 47, which can limit the threaded rod 47 to rotate only along its own axis, reduce the radial sway of the threaded rod 47 during rotation, avoid jamming at the meshing point of the threaded sleeve 46 and the threaded rod 47, and ensure the stability and accuracy of the up and down movement of the drive block 45.

[0024] The first bevel gear 43 and the second bevel gear 48 mesh with each other. The diameter of the first bevel gear 43 is equal to the diameter of the second bevel gear 48. The meshing of the first bevel gear 43 and the second bevel gear 48 can convert the horizontal rotational power of the double-ended motor 42 into the vertical rotational power of the threaded rod 47, thus achieving precise matching of the power direction.

[0025] A limiting groove is provided on the top of the device housing 1, and the bottom of the fixing clamp 410 is slidably connected to the inside of the limiting groove. The limiting groove constrains the movement trajectory of the fixing clamp 410, limiting the fixing clamp 410 to slide horizontally only along the direction of the limiting groove, so as to prevent the fixing clamp 410 from shifting laterally during the clamping process.

[0026] For example, such as Figures 1-5 The operator starts the double-ended motor 42. The output shaft of the double-ended motor 42 drives the bevel gear 43 to rotate. Since the bevel gear 43 meshes with the bevel gear 48 and has the same diameter, the bevel gear 48 rotates synchronously with the bevel gear 43 and drives the threaded rod 47 to rotate. The threaded rod 47 rotates stably under the support and limit of the rotating sleeve 411. Its meshing transmission with the threaded sleeve 46 is converted into the vertical movement of the threaded sleeve 46, which in turn drives the drive block 45 to slide up and down along the sliding groove 44 on the side of the support column 2. When the drive block 45 moves, it pulls the connecting rod 49 to deflect. The connecting rod 49 pushes the fixing clamp 410 to slide horizontally along the limiting groove on the top of the equipment housing 1. The two symmetrical fixing clamps 410 move closer to each other until they clamp the bolt to be stamped, providing stable clamping for the subsequent stamping operation of the stamping machine 3 and preventing the bolt from shifting.

[0027] like Figures 1-5 This illustration shows a bolt fixing device for a bolt stamping equipment according to another embodiment of the present invention, comprising: a lubrication device 5, the lubrication device 5 including an oil tank 51, the bottom of the oil tank 51 being fixedly connected to the bottom of the inner wall of the equipment housing 1, the top of the oil tank 51 being fixedly connected to an oil supply pipe 52, one end of a double-ended motor 42 being fixedly connected to a threaded rod 53, the circumferential surface of the threaded rod 53 being threadedly connected to a threaded sleeve 54, the side of the threaded sleeve 54 being fixedly connected to a moving plate 55, the side of the moving plate 55 being fixedly connected to a transmission plate 56, the side of the transmission plate 56 being fixedly connected to a pressing rod 57, the circumferential surface of the pressing rod 57 being slidably connected inside the oil tank 51.

[0028] In some examples, a slide rail 58 is fixedly connected to the bottom of the inner wall of the device housing 1, and a smooth rod 59 is fixedly connected to the side of the inner wall of the device housing 1. The slide rail 58 provides a stable sliding support foundation for the moving plate 55, while the smooth rod 59 can initially constrain the moving direction of the moving plate 55. The two work together to lay a structural foundation for the smooth sliding of the moving plate 55 and prevent the moving plate 55 from tilting due to lack of support.

[0029] The bottom of the movable plate 55 is slidably connected to the top of the slide rail 58. The circumferential surface of the smooth rod 59 passes through and is slidably connected to the side of the movable plate 55. The sliding of the movable plate 55 along the slide rail 58 can greatly reduce the bottom friction resistance, making the movable plate 55 respond more quickly to the drive of the threaded rod 53. The smooth rod 59 passes through the movable plate 55 and restricts its lateral displacement, ensuring that the movable plate 55 always moves in a straight line, and avoiding meshing failure between the threaded sleeve 54 and the threaded rod 53 due to displacement.

[0030] Two threaded sleeves 54, two threaded rods 53, and two oil supply pipes 52 are provided, and they are symmetrical to each other along the vertical central axis of the double-ended motor 42. One end of the oil supply pipe 52 is located at the top of the bevel gear 43. The two symmetrical threaded sleeves 54 and threaded rods 53 can synchronously drive the moving plates 55 on both sides, so that the squeezing force of the extrusion rod 57 on the oil tank 51 is balanced, ensuring stable output of lubricating oil. One end of the oil supply pipe 52 is aligned with the top of the bevel gear 43, which can accurately deliver lubricating oil to the meshing gap between the bevel gear 43 and the bevel gear 48, avoiding gear wear due to insufficient lubrication.

[0031] The displacement trajectory of the transmission plate 56 does not contact the side of the oil tank 51, and the displacement trajectory of the moving plate 55 does not contact the inner wall side of the equipment housing 1. The displacement trajectory of the transmission plate 56 avoids the side of the oil tank 51, which can prevent the transmission plate 56 from colliding with the oil tank 51 during movement, causing deformation of the oil tank 51 or damage to the transmission plate 56. The displacement trajectory of the moving plate 55 avoids the inner wall side of the equipment housing 1, which can prevent the moving plate 55 from rubbing against the housing wall and causing scratches or jamming, ensuring smooth movement of all components of the lubrication device 5.

[0032] For example, such as Figures 1-5 When the double-ended motor 42 is running, one end of it synchronously drives two symmetrical threaded rods 53 to rotate. The threaded rods 53 mesh with the threaded sleeves 54. Under the support of the slide rail 58 and the guidance of the smooth rod 59, the threaded sleeves 54 drive the moving plate 55 to move in a straight line. The moving plate 55 drives the transmission plate 56 to move synchronously. The transmission plate 56 pushes the extrusion rod 57 to slide into the oil tank 51. The extrusion rod 57 applies pressure to the lubricating oil in the oil tank 51, so that the lubricating oil is transported through the oil pipe 52 to the meshing gap between the bevel gear 43 and the bevel gear 48, realizing real-time lubrication of the gear transmission parts. Since the displacement trajectory of the transmission plate 56 avoids the side of the oil tank 51 and the displacement trajectory of the moving plate 55 avoids the inner wall of the equipment shell 1, there is no collision or jamming of parts in the entire lubrication process. Moreover, the symmetrical structure ensures that both gears can obtain uniform lubricating oil, effectively reducing gear wear and extending the transmission life of the clamping device 4.

[0033] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
