Description

Technical Field

[0001] This invention relates to the field of parts processing technology, and in particular to a staggered clamping and drilling device for automotive parts. Background Technology

[0002] With the development of the times, cars have entered thousands of households, and people's demand for cars is increasing. Car parts are essential products that support cars, and the manufacturing of car parts determines the overall quality of the car. The quality of the car can improve the safety of people when driving the car. In the process of manufacturing car parts, drilling operations are required for the parts.

[0003] According to Chinese Patent Publication No. CN108115173B, a staggered clamping and drilling device for automotive parts is disclosed, including a base, a support plate mounted on the base for support, a drilling device for drilling workpieces mounted on the base, lifting devices at both ends of the drilling device, and a clamping device for staggered clamping of the workpiece between the two lifting devices. The drilling unit includes a spring mounted on the support plate, a drilling motor mounted on the spring, and drill bits mounted on the drilling motor, the drill bits having different diameters. The clamping mechanism includes a clamping motor cooperating with a crank, a clamping gear connected to the clamping motor, a first bracket rack plate distributed at both ends of the clamping gear, and a second bracket rack plate cooperating with the first bracket rack plate. The first bracket rack plate meshes with the clamping gear. When the clamping motor rotates, the clamping gear rotates, causing the first and second bracket rack plates to come close together to clamp the workpiece. Then, the motor rotates, causing the workpiece to fall above the drilling device. When the above-mentioned device is used to drill holes in large parts, the clamping effect of the parts by only the first and second bracket rack plates is poor. As a result, the parts are prone to displacement during the drilling process, which affects the drilling effect on automotive parts.

[0004] Therefore, when using the above-mentioned device, the clamping effect is poor when drilling holes in automotive parts, which affects the accuracy of drilling. Summary of the Invention

[0008] The drive assembly is located on the upper part of the worktable, near the clamping assembly and the punching assembly. The drive assembly is used to adjust the transmission relationship between the clamping assembly and the punching assembly. The clamping components include: There are multiple lead screws, which are symmetrically rotated and installed on both sides of the worktable.

[0015] The second clamping plate is hinged to the top of the second connecting rod and is used to abut against both ends on the other side of the part body.

[0016] The limiting rod is fixed to the upper part of the worktable near the second connecting rod, and the limiting rod vertically passes through the second connecting rod.

[0017] The two first lead screws have symmetrical threads at both ends on the upper part, and the threads are in opposite directions.

[0018] The punching assembly includes: The second lead screw is rotatably mounted on the worktable on one side near the first lead screw, along its length.

[0019] The second connecting gear is fixed to one end of the upper part of the second lead screw.

[0023] The electric telescopic pole is fixed to the drive motor.

[0024] The transmission cylinder is movably connected to the power output end of the drive motor, and the power output end of the electric telescopic rod is rotatably mounted on the transmission cylinder.

[0025] The first transmission gear is fixed to one end of the transmission cylinder.

[0026] The second transmission gear is fixed to the other end of the transmission cylinder.

[0027] The drive motor has protrusions evenly installed along the circumference at its power output end, and the inner side of the transmission cylinder has grooves of a size that correspond to the positions of the protrusions.

[0028] The first transmission gear is connected to the first connecting gear, and the second transmission gear is connected to the second connecting gear. The first transmission gear, the first connecting gear, the second transmission gear, and the second connecting gear are all bevel gears.

[0029] A further preferred embodiment is that the punch can move laterally on the mounting frame, and the mounting frame is provided with a sliding groove that matches the movement trajectory of the punch.

[0030] A further preferred embodiment is that a collection bin is fixedly connected to the bottom of the workbench near the placement block, and the placement block is provided with uniformly distributed discharge holes.

The driving component allows for adjustment of the clamping components' clamping on both sides of the part body during processing. When drilling, the driving component disengages from the clamping components, ensuring the clamping components remain in a clamping state. The driving component then drives the drilling component to move, improving the accuracy of the drilling component. Attached Figure Description

[0034] A prior art disclosed staggered clamping and drilling device for automotive parts includes a base and a support plate mounted on the base for support. A drilling device for drilling workpieces is mounted on the base. Lifting devices are located at both ends of the drilling device, and a clamping device for staggered clamping of the workpiece is located between the two lifting devices. The drilling unit includes a spring mounted on the support plate, a drilling motor mounted on the spring, and drill bits of different diameters mounted on the drilling motor. The clamping mechanism includes a clamping motor that engages with a crank, a clamping gear connected to the clamping motor, a first rack plate with a support rack plate distributed at both the upper and lower ends of the clamping gear, and a second rack plate that engages with the first rack plate. The first rack plate meshes with the clamping gear. Rotation of the clamping motor and the clamping gear causes the first and second rack plates to come close together, clamping the workpiece. Then, the motor rotates, causing the workpiece to fall above the drilling device. When the above-mentioned device is used to drill holes in large parts, the clamping effect of the parts by only the first and second bracket rack plates is poor. As a result, the parts are prone to displacement during the drilling process, which affects the drilling effect on automotive parts.

[0035] Therefore, when using the above-mentioned device, the clamping effect is poor when drilling holes in automotive parts, which affects the accuracy of drilling.

[0036] To address the aforementioned technical problems, this application proposes the following design and concept: In order to solve the problems existing in the prior art, it is envisioned that a certain misaligned clamping mechanism has a better clamping effect on parts than the bracket rack plate one and bracket rack plate two in the prior art, thereby achieving the purpose of precise drilling.

[0037] The following is in conjunction with the appendix Figures 1 to 5 The present invention will be described in further detail below.

[0038] A staggered clamping and drilling device for automotive parts, such as Figure 1 As shown, the system includes a workbench 1 and a placement block 3 fixedly disposed at the upper middle position of the workbench 1. A part body 6 is placed on the placement block 3. For example, the part body 6 can be a car beam. The system also includes: The clamping assembly 2 is symmetrically rotated along the length direction and installed on both sides of the upper part of the worktable 1 near the placement block 3. The clamping assembly 2 is used to clamp both sides of the part body 6.

[0039] The drilling assembly 4 is symmetrically rotated along the length direction and installed at the upper edge of the worktable 1. The drilling assembly 4 is used to drill holes in the part body 6.

[0040] The drive assembly 5 is located on the upper part of the worktable 1, near the clamping assembly 2 and the punching assembly 4. The drive assembly 5 is used to adjust the transmission relationship between the clamping assembly 2 and the punching assembly 4.

[0041] With the clamping components 2 set on both sides of the worktable 1, when drilling is performed on the part body 6, the clamping components 2 clamp the two sides of the part body 6, thereby achieving misaligned clamping and further improving the clamping effect of the part body 6. With the setting of the drilling component 4, after clamping the part body 6, the drilling efficiency is improved when drilling the part body 6. With the setting of the drive component 5, when processing the part body 6, the clamping components 2 can be adjusted to clamp the two sides of the part body 6. When drilling the part body 6, the drive component 5 disengages from the transmission of the clamping components 2, so that the clamping components 2 always maintain the clamping state. The drive component 5 drives the drilling component 4 to move, improving the accuracy of the drilling component 4.

[0042] Specifically, such as Figure 1 and Figure 3 As shown, the clamping assembly 2 includes: Multiple lead screws 21 are symmetrically and rotatably mounted on both sides of the worktable 1. The two lead screws 21 are parallel to the length direction of the worktable 1. Furthermore, the two lead screws 21 are of equal length and parallel to each other, and are connected by a belt.

[0043] There are two first sliding blocks 22, which are symmetrically threaded to both ends of the first lead screw 21.

[0044] The first connecting rod 23 is rotatably mounted on the first sliding block 22. Furthermore, the mounting direction of the first connecting rod 23 is towards the side closer to the part body 6.

[0045] The first clamping plate 24 is hinged to one end of the two first connecting rods 23 and abuts against one side of the part body 6.

[0046] The first connecting gear 25 is fixedly connected to one end of a first lead screw 21.

[0047] Furthermore, when the first lead screw 21 rotates, the two first sliding blocks 22 move closer to each other, thereby driving the first clamping plate 24 to move through the first connecting rod 23. Specifically, the first clamping plate 24 moves from the side away from the first lead screw 21 toward the side of the part body 6, thereby causing the first clamping plate 24 to abut against the part body 6, thus fixing one side of the part body 6.

[0048] Specifically, such as Figure 1 and Figure 3 As shown, the clamping assembly 2 also includes: There are two second sliding blocks 26, which are symmetrically threaded to both ends of another first lead screw 21.

[0049] The second connecting rod 27 is hinged to the end of the second sliding block 26. Furthermore, the mounting direction of the second connecting rod 27 is towards the other side close to the part body 6.

[0050] The second clamping plate 28 is hinged to the top of the second connecting rod 27 and is used to abut against both ends on the other side of the part body 6.

[0051] The limiting rod 29 is fixedly connected to the upper part of the worktable 1 near the second connecting rod 27, and the limiting rod 29 vertically passes through the second connecting rod 27.

[0052] Furthermore, when one set of first lead screws 21 drives another set of first lead screws 21 to rotate, the two second sliding blocks 26 move in opposite directions on the other set of first lead screws 21. Then, the second sliding blocks 26 drive the second clamping plate 28 to abut against the other side of the part body 6 through the second connecting rod 27, thereby fastening the other side of the part body 6 and fixing the part body 6 on the placement block 3, thus achieving misaligned clamping of the placement block 3.

[0053] Specifically, such as Figure 3 As shown, the two first lead screws 21 have symmetrical threads at both ends on the upper part, and the threads are in opposite directions.

[0054] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the punching component 4 includes: The second lead screw 41 is rotatably mounted on the worktable 1 on one side near a first lead screw 21 along its length. Furthermore, a fixing rod is mounted on the other side of the worktable 1. Specifically, the fixing rod and the second lead screw 41 are of equal length and parallel.

[0055] The second connecting gear 42 is fixedly connected to one end of the upper part of the second lead screw 41.

[0056] Mounting bracket 43 is threaded onto second lead screw 41. Second lead screw 41 is used to drive mounting bracket 43 to move. Specifically, mounting bracket 43 is mounted in a U-shape on second lead screw 41 and fixed rod.

[0057] The punch 44 is slidably mounted on the mounting bracket 43. The punch 44 is used to punch holes in the part body 6. Specifically, the punch 44 is connected to an external power supply and control panel.

[0058] Furthermore, when the second lead screw 41 rotates, the mounting bracket 43 slides on the second lead screw 41 and the fixed rod, thereby changing the longitudinal drilling position of the punch 44. When the punch 44 moves on the mounting bracket 43, it changes the lateral drilling position of the punch 44, thereby improving the drilling efficiency of the punch 44.

[0059] Specifically, such as Figure 2 As shown, the punch 44 can move laterally on the mounting bracket 43, and the mounting bracket 43 is provided with a sliding groove that matches the movement trajectory of the punch 44.

[0060] Specifically, Figure 1 , Figure 4 and Figure 5 As shown, the driving component 5 includes: The drive motor 51 is fixedly connected to the worktable 1 at a position near the opposite side of the first lead screw 21 and the second lead screw 41. Furthermore, the drive motor 51 is connected to an external power supply and control panel.

[0061] The electric telescopic pole 52 is fixedly connected to the drive motor 51. Furthermore, the electric telescopic pole 52 is connected to an external power supply and control panel.

[0062] The transmission cylinder 53 is movably connected to the power output end of the drive motor 51. The power output end of the electric telescopic rod 52 is rotatably mounted on the transmission cylinder 53. Specifically, a connecting block is rotatably mounted on the transmission cylinder 53, and the power output end of the electric telescopic rod 52 drives the transmission cylinder 53 to move through the connecting block. When the drive motor 51 drives the transmission cylinder 53 to rotate, it does not affect the extension and retraction of the electric telescopic rod 52.

[0063] The first transmission gear 54 is fixedly connected to one end of the transmission cylinder 53. Specifically, the first transmission gear 54 is fixedly connected to one end near the first connecting gear 25.

[0064] The second transmission gear 55 is fixedly connected to the other end of the transmission cylinder 53. Specifically, the second transmission gear 55 is fixedly connected to one end near the second connecting gear 42.

[0065] Specifically, such as Figure 5 As shown, protrusions are evenly installed along the circumferential direction on the power output end of the drive motor 51, and a groove of a size that matches the position of the protrusion is provided on the inner side of the transmission cylinder 53.

[0066] Furthermore, when clamping the part body 6, the electric telescopic rod 52 drives the transmission cylinder 53 to move, and the first transmission gear 54 meshes with the first connecting gear 25. At this time, the drive motor 51 starts and drives the first connecting gear 25 to rotate through the transmission cylinder 53 and the first transmission gear 54, thereby causing the first lead screw 21 to rotate, thus clamping the part body 6. When the electric telescopic rod 52 drives the transmission cylinder 53 to move in the opposite direction, the first transmission gear 54 disengages from the first connecting gear 25, and the second transmission gear 55 meshes with the second connecting gear 42. When the drive motor 51 starts, the drive motor 51 drives the second connecting gear 42 to rotate through the transmission cylinder 53 and the second transmission gear 55, thereby causing the second lead screw 41 to rotate, thereby adjusting the position of the mounting bracket 43 and further changing the drilling position of the drilling machine 44.

[0067] Specifically, such as Figure 5 As shown, the first transmission gear 54 is driven to the first connecting gear 25, and the second transmission gear 55 is driven to the second connecting gear 42. The first transmission gear 54, the first connecting gear 25, the second transmission gear 55, and the second connecting gear 42 are all bevel gears, which improves the meshing stability between the first transmission gear 54, the first connecting gear 25, the second transmission gear 55, and the second connecting gear 42.

[0068] Specifically, such as Figure 2 As shown, a collection bin 7 is fixedly connected to the bottom of the workbench 1 near the placement block 3. The placement block 3 is evenly provided with discharge holes. When drilling is performed on the part body 6, the generated debris falls into the collection bin 7 through the discharge holes, thereby effectively keeping the placement block 3 clean and facilitating the centralized treatment of debris.

[0069] Working principle In use, the part body 6 is placed on the placement block 3. At this time, the electric telescopic rod 52 drives the transmission cylinder 53 to move, and the first transmission gear 54 meshes with the first connecting gear 25. The drive motor 51 starts and drives the first connecting gear 25 to rotate through the transmission cylinder 53 and the first transmission gear 54, which in turn causes a set of first lead screws 21 to rotate. One set of first lead screws 21 drives the other set of first lead screws 21 to rotate through a belt. When the first set of first lead screws 21 rotates, the two first sliding blocks 22 move closer to each other, and the two first sliding blocks 22 drive the first clamp through the first connecting rod 23. The plate 24 moves. Specifically, the first clamping plate 24 moves from the side away from the first lead screw 21 toward the side of the part body 6, thereby making the first clamping plate 24 abut against the part body 6 and fixing one side of the part body 6. When one set of first lead screws 21 drives another set of first lead screws 21 to rotate, the two second sliding blocks 26 move in opposite directions on the other set of first lead screws 21. Then, the second sliding blocks 26 drive the second clamping plate 28 to abut against the other side of the part body 6 through the second connecting rod 27, thereby fastening the other side of the part body 6 and fixing the part body 6 on the placement block 3, thereby achieving misaligned clamping of the placement block 3.

[0070] After the part body 6 is clamped, the electric telescopic rod 52 drives the transmission cylinder 53 to move in the opposite direction. As a result, the first transmission gear 54 disengages from the first connecting gear 25, and the second transmission gear 55 meshes with the second connecting gear 42. When the drive motor 51 starts, the drive motor 51 drives the second connecting gear 42 to rotate through the transmission cylinder 53 and the second transmission gear 55. As a result, the second lead screw 41 rotates and the mounting bracket 43 slides on the second lead screw 41 and the fixed rod. As a result, the mounting bracket 43 changes the longitudinal drilling position of the punch 44. When the punch 44 moves on the mounting bracket 43, it changes the transverse drilling position of the punch 44. The generated debris falls into the collection bin 7 through the discharge hole, which facilitates the centralized processing of the debris.

[0071] This specific embodiment is merely an explanation of the invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of protection of this invention, they are protected by patent law.
