Description

Technical Field

[0001] The utility model belongs to the field of automobile chassis, and in particular relates to a supporting device of a longitudinal beam drilling machine. Background Art

[0002] With the rapid development of the automotive industry, the processing technology of frame longitudinal beams is constantly changing, mainly to achieve the drilling and drilling of different series of slot beams and flat beams. The traditional longitudinal beam drilling device can only process slot beams, but cannot drill flat beams, which cannot meet the requirements of the new drilling process solution. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model aims to provide a supporting device for a longitudinal beam drilling machine, which can adapt to the processing of different beams through structural changes to solve the above-mentioned problems.

[0004] In order to solve the above problems existing in the prior art, the technical solution adopted by the utility model is:

[0005] The supporting device of the longitudinal beam drilling machine comprises: a moving component, a supporting component and a clamping structure.

[0006] The mobile assembly includes a travel motor, a guide rail, a travel wheel and a support platform. The guide rail is connected to the ground, and the travel wheel and the travel motor are both connected to the support platform. The travel motor is used to drive the travel wheel to rotate, and the travel wheel is rollingly connected to the guide rail.

[0007] The support assembly includes a support seat and a support body. The support seat is connected to the support body through a bearing structure. The support body is connected to a rotating assembly, and the rotating assembly is used to drive the support body to rotate.

[0008] The clamping structure is detachably connected to the supporting assembly.

[0009] By splicing multiple support bodies into a support assembly, then using a moving assembly to drive the support assembly to move as a whole, and finally using a rotating assembly to drive the support body to rotate, the front and side surfaces of the longitudinal beam can be punched once, thereby improving work efficiency.

[0010] Furthermore, the travel motor drives the travel wheel to rotate through a worm gear reducer, and the worm gear reducer is used for transmission, so as to facilitate the precise control of the moving distance of the support body and improve the product quality. There are multiple support seats, and the support body includes multiple support sections. Both ends of each support section are provided with outer circular plates, and two adjacent support sections are connected by an intermediate shaft. The intermediate shaft is rotatably connected to the support seat, and both ends of the intermediate shaft are provided with inner circular plates, and the inner circular plate and the outer circular plate are connected by an anti-rotation pin.

[0011] Furthermore, the support section includes an upper channel steel and a lower channel steel, the side edges of the upper channel steel and the lower channel steel are welded through side plates, and the side plates are provided with a plurality of clamping openings, and the clamping openings are used to connect the clamping structure.

[0012] Furthermore, the support section is connected to a positioning assembly, and the positioning assembly includes a first positioner or a second positioner, the first positioner includes two first adjustment plates and two plug-in pins, the first adjustment plates are connected to the support section through the plug-in pins, and the second positioner includes two second adjustment plates and two plug-in pins, and the second adjustment plates are connected to the support section through the plug-in pins.

[0013] Furthermore, the support section is also connected to a support card platform, and the support card platform is located between the two adjustment plates. The support card platform mainly plays a supporting role. When the workpiece is a flat beam, it is easy to cause a depression in the middle of the flat beam when punching. A support card platform is added to the support section, and the support card platform supports the middle part of the workpiece to avoid deformation of the workpiece during punching. The support card platform is detachably connected with a support block. Due to the different structures of the longitudinal beam, when the longitudinal beam is a "concave" structure, the longitudinal beam needs to be buckled on the support body for processing during punching. At this time, the support card platform cannot contact the workpiece. Therefore, the support block can be connected to the support card platform, so that the support block can contact the longitudinal beam and play a supporting role.

[0014] Furthermore, the rotating assembly is connected to a brake, and the brake is provided to facilitate the control of the rotation angle of the supporting body so that each rotation is 90°.

[0015] Furthermore, the support column is connected to the intermediate shaft with a split-type bearing structure, and a support seat at one end is hinged with a positioning block, and the positioning block is used to limit the support body. By setting the positioning block and setting a corresponding positioning groove at the end of the support body, when the support body is rotated 90°, the positioning block is just stuck in the positioning groove. If the support body needs to continue to be rotated, the positioning block needs to be manually removed before the support body can be rotated.

[0016] The beneficial effects of the utility model are:

[0017] 1. The utility model adopts a split bearing shell and a small gap between the shaft, and the support seat is used as the main support. Four support points are set along the entire length as the main support to improve the stability of the support.

[0018] 2. The utility model adopts a rectangular hollow steel welded in the core of the main body, which not only improves the overall strength of the whole device, but also forms a bow-shaped clamping space to achieve clamping.

[0019] 3. The utility model designs positioning blocks of different series and specifications. Considering the need to frequently replace the positioning blocks to achieve positioning, a hand-pull positioner is used to achieve rapid positioning.

[0020] 4. The utility model can meet the needs of drilling holes and through holes on the bottom surface of the frame longitudinal beam, 90-degree wing hole holes on both sides, and can achieve full-circle flipping of 90°-270°. It can move horizontally to achieve full-beam drilling coverage by four drilling machines, flexible rotation and reliable flipping and clamping. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0032] Embodiment 1:

[0033] like Figure 1 As shown, the supporting device of the longitudinal beam drilling machine includes: a moving component, a supporting component and a clamping structure 9.

[0034] The mobile assembly includes a travel motor 8, a guide rail 4, a travel wheel 3 and a support platform 10. The guide rail 4 is connected to the ground. The travel wheel 3 and the travel motor 8 are both connected to the support platform 10. The travel motor 8 is used to drive the travel wheel 3 to rotate. The travel wheel 3 is rollingly connected to the guide rail 4.

[0035] The support assembly includes a support seat 2 and a support body 1. The support seat 2 is connected to the support body 1 through a bearing structure. The support body 1 is connected to a rotating assembly 5. The rotating assembly 5 is used to drive the support body 1 to rotate.

[0036] The clamping structure 9 is detachably connected to the supporting assembly.

[0037] By splicing multiple support bodies 1 into a support assembly, and then using a moving assembly to drive the support assembly to move as a whole, and finally driving the support body 1 to rotate through a rotating assembly 5, the front and side surfaces of the longitudinal beam can be punched once, thereby improving work efficiency.

[0038] Embodiment 2:

[0039] On the basis of Example 1, Figure 2 As shown, the travel motor 8 drives the travel wheel 3 to rotate through the transmission component 7 (the transmission component 7 here can be a worm gear reducer), and the worm gear reducer is used for transmission, which facilitates the precise control of the moving distance of the support body 1 and improves product quality.

[0040] The support seat 2 is provided with multiple, and the support body 1 includes multiple support sections, each of which is provided with an outer circular plate 23 at both ends of the support section, and the adjacent two support sections are connected by an intermediate shaft 24, and the intermediate shaft 24 is rotatably connected to the support column 22, and an inner circular plate 21 is provided at both ends of the intermediate shaft 24, and the inner circular plate 21 and the outer circular plate 23 are connected by an anti-rotation pin 25.

[0041] Figure 1 Four middle support seats 2 are drawn, one at each end and two in the middle, and a total of three support segments are connected between the four support seats 2. The support column 22 plays a supporting role, but does not limit the rotation of the intermediate shaft 24, thereby ensuring that the support body 1 can rotate freely on the support seat 2. In addition, the inner circular plate 21 and the outer circular plate 23 are connected by an anti-rotation pin 25, and then the rotating assembly 5 is connected at one end of the support assembly, so that multiple support segments can rotate synchronously.

[0042] Embodiment 3:

[0043] On the basis of Example 2, Figure 3 As shown, the support section includes an upper channel steel 11 and a lower channel steel 12 , the side edges of the upper channel steel 11 and the lower channel steel 12 are welded through a side plate 13 , and the side plate 13 is provided with a plurality of clamping openings 131 , and the clamping openings 131 are used to connect the clamping structure 9 .

[0044] After the longitudinal beam is connected, in order to prevent the longitudinal beam from moving and falling, the longitudinal beam and the supporting body 1 need to be clamped by a clamping structure 9. During clamping, one end of the clamping structure 9 extends into the clamping opening 131, and the other end of the clamping structure 9 presses on the longitudinal beam.

[0045] Embodiment 4:

[0046] On the basis of Example 3, Figure 4 and 5 As shown, the support segment is connected to a positioning assembly 14, and the positioning assembly 14 includes a first positioner or a second positioner.

[0047] The first positioner includes two first adjustment plates 141 and two plug-in pins 142 (only one side is shown in the figure, and the plug-in pins 142 and the first adjustment plates 141 are actually symmetrically arranged), and the first adjustment plates 141 are connected to the support section through the plug-in pins 142.

[0048] The second positioner includes two second adjustment plates 143 and two plug-in pins 142 (only one side is shown in the figure, and the plug-in pins 142 and the second adjustment plates 143 are actually symmetrically arranged), and the second adjustment plates 143 are connected to the supporting section through the plug-in pins 142.

[0049] The positioning assembly 14 is used to limit the longitudinal beam to prevent the longitudinal beam from sliding left and right. Different positioning assemblies 14 can be selected for positioning according to the different longitudinal beam structures. Two positioning assemblies 14 are listed in this application. Although both use plug-in pins 142 for disassembly and connection, the specific structures are different.

[0050] The support section is also connected to a support clamping platform 15 , and the support clamping platform 15 is located between two adjustment plates (the adjustment plates here represent the first adjustment plate 141 and the second adjustment plate 142 ).

[0051] The supporting table 15 mainly plays a supporting role. When the workpiece is a flat beam, it is easy to cause a dent in the middle of the flat beam when drilling. The supporting table 15 is added to the supporting section to support the middle of the workpiece to avoid deformation of the workpiece when drilling.

[0052] The support clamping platform 15 is detachably connected to a support block 16 .

[0053] Due to the different structures of the longitudinal beam, when the longitudinal beam is a "concave" structure, the longitudinal beam needs to be buckled on the support body 1 for processing when drilling. At this time, the support clamping table 15 cannot contact the workpiece, so the support block 16 can be connected to the support clamping table 15, so that the support block 16 can contact the longitudinal beam and play a supporting role.

[0054] Embodiment 5:

[0055] On the basis of Embodiment 4, the rotating assembly 5 is connected with a brake 6 .

[0056] The brake 6 is provided to facilitate the control of the rotation angle of the support body 1 so that each rotation is 90°.

[0057] The support column 22 is connected to the intermediate shaft 24 by adopting a split bearing structure.

[0058] A positioning block 17 is hingedly connected to the support seat 22 at one end, and the positioning block 17 is used to limit the position of the support body 1.

[0059] By setting a positioning block 17 and a corresponding positioning groove at the end of the support body 1, when the support body 1 is rotated 90°, the positioning block 17 is just stuck in the positioning groove. If the support body 1 needs to be further rotated, the positioning block 17 needs to be manually removed before the support body 1 can be rotated.

[0060] Specific working principle:

[0061] When in use, first stack multiple longitudinal beams in sequence (during actual processing, they are not processed one by one, but multiple longitudinal beams are processed simultaneously) on the support body 1, and then connect the positioning components 14 on both sides of the longitudinal beam to achieve the positioning of the longitudinal beam, and then connect the clamping structure 9 to the clamping mouth 131, and use the clamping structure 9 to clamp the longitudinal beam to prevent it from moving during processing, and then control the travel motor 8 and the rotating component 5 to adjust the position according to the required hole position to achieve precise drilling of the longitudinal beam.

[0062] The present utility model is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
