Description

Technical Field

[0001] This utility model relates to the field of fixtures for processing automotive parts, and in particular to a multi-directional adjustable clamping device for automotive parts. Background Technology

[0002] In the processing and assembly of automotive parts, automotive parts clamping devices are used to position and clamp the parts, and then perform relevant processing and inspection procedures on the clamped and fixed parts.

[0003] Existing clamping devices are mostly fixed in the horizontal direction. When dealing with different automotive parts, existing clamping devices achieve compatibility with different tilt angles of the parts by changing the matching positioning base. Every time the part model is changed, key components such as the positioning base need to be disassembled and the clamping needs to be readjusted. This not only consumes a lot of time and manpower, but also easily leads to wear and tear of the parts due to frequent disassembly, affecting the positioning accuracy and service life of the clamp. Summary of the Invention

[0004] This disclosure relates to a multi-directional adjustable automotive parts clamping device. Through the coordinated operation of the middle support frame and the lower support plate, the upper clamping platform can achieve lateral and longitudinal tilt adjustment, effectively addressing the differences in processing positions of different automotive parts. It avoids the need for cumbersome disassembly and readjustment of key components such as the positioning backrest base due to different part positions. According to the processing requirements of different automotive parts, the tilt angle of the upper clamping platform and the automotive parts clamped on its top can be flexibly and accurately adjusted, improving the compatibility with various automotive parts.

[0005] In a first aspect, this disclosure provides a multi-directional adjustable automotive parts clamping device, specifically comprising: an upper clamping platform, a middle support frame, and a lower base. The middle support frame is disposed below the upper clamping platform, and the lower base is disposed below the middle support frame. A positioning backing base and a side connecting frame are bolted to the top of the upper clamping platform. An upper positioning telescopic cylinder is fixedly disposed on the upper part of the side connecting frame. The positioning backing base and the side connecting frame are arranged opposite to each other at intervals. A lower turntable is fixedly disposed on the lower part of the upper clamping platform. The lower part of the lower turntable is fixedly connected to the top of the middle support frame. A positioning screw is screwed into the middle of the lower turntable. The lower turntable is composed of two inner and outer cylindrical rings rotatably connected. The inner and outer cylindrical rings of the lower turntable are respectively fixed to the upper clamping platform and the middle support frame. The positioning screw screwed into the outer cylindrical ring of the lower turntable tightens against the inner cylindrical ring of the lower turntable to fix the angle.

[0006] In at least some embodiments, the bottom of the middle support frame and the upper end of the lower support frame are rotatably connected by a rotating shaft. The lower support frame is a rectangular rod structure. The lower end of the lower support frame and the upper movable slider are rotatably connected by a rotating shaft. The upper movable slider slides horizontally on the top of the lower support plate. An electric screw is rotatably provided on the top of the lower support plate. The electric screw is driven to rotate by a motor provided on the top of the lower support plate.

[0007] In at least some embodiments, the upper movable slider and the electric screw are screwed together, the bottom of the middle support frame and the top of the lower support plate are rotatably connected by a rotating shaft, and the bottom of the lower support plate and the top of the lower base are rotatably connected by a rotating shaft.

[0008] In at least some embodiments, the bottom of the lower support plate is rotatably connected to another lower bracket via a rotating shaft. The lower end of the lower bracket at the bottom of the lower support plate and another upper movable slider slidably disposed at the top of the lower base are rotatably connected via a rotating shaft. The upper movable slider at the top of the lower base is screwed into another electric screw rotating at the top of the lower base. The motor drives the electric screw to rotate, and the thread of the electric screw drives the upper movable slider to move axially. The upper movable slider pulls the lower bracket to move synchronously, and the lower bracket changes the support angle between the center support frame and the lower support plate.

[0009] In at least some embodiments, lower positioning telescopic cylinders are fixedly provided on both sides of the lower base, and the first end of the telescopic rod of the lower positioning telescopic cylinder is provided with a side limiting frame through a rotating shaft.

[0010] In at least some embodiments, the rotation directions of the lower support bracket at the bottom of the middle support frame and the lower support plate at the bottom are staggered at right angles in the horizontal and vertical directions, and the rotation directions of the middle support frame and the lower support plate are staggered at right angles in the horizontal and vertical directions, so as to realize the adjustment of the tilt angle in both the horizontal and vertical directions. The upper clamping platform is adjusted in both the horizontal and vertical directions along with the middle support frame, so as to realize the adjustment of the tilt angle of the upper clamping platform and the top automotive parts.

[0011] In at least some embodiments, the side limiting frames on both sides of the lower base are located on both sides of the middle support frame. The lower positioning telescopic cylinder extends to support the side limiting frames and the sides of the middle support frame to keep them in close contact and press tightly, thereby enhancing the support force on the middle support frame and reducing the shaking of the middle support frame during processing.

[0012] This utility model provides a multi-directional adjustable automotive parts clamping device, which has the following beneficial effects:

[0013] Through the coordinated operation of the middle support frame and the lower support plate, the upper clamping platform can achieve lateral and longitudinal tilt adjustment, effectively addressing the differences in processing positions of different automotive parts. This avoids the need for tedious disassembly and readjustment of key components such as the positioning base due to different part positions. Based on the processing requirements of different automotive parts, the tilt angle of the upper clamping platform and the automotive parts clamped on top can be flexibly and accurately adjusted, significantly improving the compatibility of the clamping device with various automotive parts and greatly enhancing production efficiency and processing flexibility.

[0014] After the middle support frame is positioned, the side limiting frames on both sides of the lower base, driven by the corresponding lower positioning telescopic cylinders, tightly fit and clamp the middle support frame, effectively enhancing the support force on the middle support frame, reducing the swaying of the middle support frame due to its height during processing, reducing the pressure on the middle support frame and the supporting shaft of the lower bracket during processing, thereby effectively extending the service life of the supporting shaft, reducing equipment maintenance costs, and ensuring the stability and continuity of the production process.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] This utility model proposes a multi-directional adjustable automotive parts clamping device, comprising: an upper clamping platform 1, a middle support frame 2, and a lower base 3. The top of the upper clamping platform 1 is bolted to a positioning backing base 101 and a side connecting frame 102. An upper positioning telescopic cylinder 103 is fixedly installed on the upper part of the side connecting frame 102. The positioning backing base 101 and the side connecting frame 102 are arranged opposite each other at intervals. A lower turntable 104 is fixedly installed on the lower part of the upper clamping platform 1. The lower part of the lower turntable 104 is fixedly connected to the top of the middle support frame 2. A positioning screw 105 is screwed into the middle of the lower turntable 104. The lower turntable 104 is rotatably connected by two inner and outer cylindrical rings. The lower turntable 104 has two cylindrical rings, one inside and one outside, fixed to the upper clamping platform 1 and the middle support frame 2, respectively. The positioning screws 105 screwed onto the outer cylindrical ring of the lower turntable 104 tighten the inner cylindrical ring of the lower turntable 104 to fix the angle. The middle support frame 2 is located below the upper clamping platform 1. The bottom of the middle support frame 2 and the upper end of the lower bracket 201 are rotatably connected via a rotating shaft. The lower bracket 201 is a rectangular rod structure. The lower end of the lower bracket 201 and the upper movable slider 203 are rotatably connected via a rotating shaft. The upper movable slider 203 slides horizontally on the top of the lower support plate 202. An electric screw 204 is rotatably mounted on the top of the lower support plate 202. The electric screw 204 is driven to rotate by a motor mounted on the top of the lower support plate 202. The upper movable slider 203 is screwed to the electric screw 204. The bottom of the middle support frame 2 and the top of the lower support plate 202 are rotatably connected by a rotating shaft. The bottom of the lower support plate 202 and the top of the lower base 3 are rotatably connected by a rotating shaft. Another lower bracket 201 is rotatably connected to the bottom of the lower support plate 202 by a rotating shaft. The lower end of the lower bracket 201 at the bottom of the lower support plate 202 and another upper movable slider 203 slidably mounted on the top of the lower base 3 are rotatably connected by a rotating shaft. The upper movable slider 203 on the top of the lower base 3 and the lower base 3 are rotatably connected by a rotating shaft. Another electric screw 204 is screwed into the top for rotation. The motor drives the electric screw 204 to rotate. The thread of the electric screw 204 drives the upper moving slider 203 to move axially. The upper moving slider 203 pulls the lower support 201 to move synchronously. The lower support 201 changes the support angle of the middle support frame 2 and the lower support plate 202. The middle support frame 2 tilts around the rotating connection between the middle support frame 2 and the lower support plate 202. A lower base 3 is set below the middle support frame 2. Lower positioning telescopic cylinders 301 are fixedly set on both sides of the lower base 3. The telescopic rod of the lower positioning telescopic cylinder 301 is rotatably set with a side limit frame 302 through a rotating shaft.

[0029] In this embodiment, the rotation directions of the lower support bracket 201 at the bottom of the middle support frame 2 and the lower support plate 202 are staggered at right angles in the horizontal and vertical directions, and the rotation directions of the middle support frame 2 and the lower support plate 202 are staggered at right angles in the horizontal and vertical directions, so as to realize the horizontal and vertical tilt angle adjustment. The upper clamping platform 1 is adjusted horizontally and vertically along with the middle support frame 2, so as to realize the adjustment of the tilt angle of the upper clamping platform 1 and the top of the automobile parts, so as to cope with the differences in the processing position of different automobile parts and improve compatibility.

[0030] In this embodiment, the side limiting frames 302 on both sides of the lower base 3 are located on both sides of the middle support frame 2. The lower positioning telescopic cylinder 301 extends to support the side limiting frames 302 and the side of the middle support frame 2 to keep them in close contact and press tightly, thereby enhancing the support force on the middle support frame 2, reducing the shaking caused by the middle support frame 2's high height during processing, and reducing the pressure borne by the middle support frame 2, the lower bracket 201, and the matching rotating shaft during processing.

[0031] In Example 2, based on Example 1, a worm gear is provided on the outer side of the lower turntable 104, and a worm is provided on the top of the middle support frame 2. The lower turntable 104 is driven to rotate by a motor. The positioning screw 105 is not set. The lower turntable 104 and the upper clamping table 1 automatically perform horizontal circumferential rotation, eliminating the need for manual rotation by personnel.

[0032] The working principle of this embodiment: The L-shaped positioning base 101 fits against one side of the lower part of the part. The telescopic rod of the upper positioning telescopic cylinder 103 extends and approaches the upper part of the positioning base 101 to clamp it, thus fixing the automotive part. The upper clamping platform 1 can change circumferentially with the lower turntable 104. The motor drives the electric screw 204 to rotate. The thread of the electric screw 204 drives the upper moving slider 203 to move axially. The upper moving slider 203 pulls the lower support 201 to move synchronously. The support angle of the lower support 201 relative to the central support frame 2 and the lower support plate 202 changes. The central support frame 2 tilts and adjusts around the rotating connection between the central support frame 2 and the lower support plate 202. The lower support plate 202 tilts and adjusts around the lower support. The rotating connection between the support plate 202 and the lower base 3 is tilted and adjusted. The upper clamping platform 1 tilts laterally and longitudinally along with the middle support frame 2 and the lower support plate 202. Through the coordinated operation of the middle support frame 2 and the lower support plate 202, the upper clamping platform 1 achieves lateral and longitudinal tilt adjustment, thereby adjusting the tilt angle of the upper clamping platform 1 and the top automotive parts. This addresses the differences in processing positions of different automotive parts, reduces the need for disassembly and adjustment of components such as the positioning base 101 due to different processing positions of automotive parts, completes the angle changes during processing of different automotive parts, improves the compatibility of different automotive parts, and adjusts the tilt angle of the upper clamping platform 1 and the automotive parts clamped on its top, thereby improving the compatibility of various automotive parts.

[0033] When the middle support frame 2 is adjusted in angle, the lower positioning telescopic cylinder 301 shortens, causing the side limiting frame 302 to move away from the middle support frame 2. After the middle support frame 2 completes the position adjustment, the side limiting frames 302 on both sides of the lower base 3, under the support of the corresponding lower positioning telescopic cylinder 301 extension, tightly fit and clamp the two sides of the middle support frame 2, avoiding the problem of the middle support frame 2 easily shaking during processing due to its high height, providing more reliable support, effectively enhancing the support force on the middle support frame 2, reducing the shaking caused by the middle support frame 2's high height during processing, reducing the pressure on the middle support frame 2 and the matching rotating shaft of the lower bracket 201 during processing, extending the service life of the matching rotating shaft, and reducing maintenance costs. The side limiting frame 302 is rotatable, and the side limiting frame 302 tilts and rotates to adapt to the angle change after the middle support frame 2 tilts. The side limiting frame 302 tilts synchronously and maintains maximum fit with the middle support frame 2 after tilting.
