Description

Technical Field

[0001] This application relates to the field of fixture technology, and in particular to a fixture for processing loading port end frames. Background Technology

[0002] The loading port end frame of the aluminum cargo vehicle body is large in size and easily deformed. Before processing the end frame, it needs to be clamped and aligned. During the processing, the end frame needs to be fixed to avoid dimensional deviations after processing.

[0003] Current fixtures involve cumbersome and time-consuming alignment processes during clamping, and their positioning effect is poor, resulting in certain clamping errors that affect machining accuracy and efficiency.

[0004] Therefore, there is an urgent need for a fixture that is simple and quick to align and has high positioning accuracy in order to improve machining accuracy and efficiency. Utility Model Content

[0005] The purpose of this application is to provide a machining fixture for the loading port end frame, which solves the tediousness of end frame alignment and eliminates positioning errors during clamping, thereby ensuring machining accuracy and improving machining efficiency.

[0006] To achieve the above objectives, this application provides a loading port end frame processing fixture, comprising:

[0007] The base plate includes the reference surface and the assembly surface;

[0008] A guide template is fixedly mounted on the assembly plane. The guide template includes three vertical surfaces and a first horizontal surface. The three vertical surfaces are a first vertical surface, a second vertical surface, and a third vertical surface. The first vertical surface and the second vertical surface are parallel, and the third vertical surface is perpendicular to the first vertical surface and the second vertical surface. The first horizontal surface is perpendicular to the three vertical surfaces.

[0009] The contour block is fixed to the first vertical surface. The contour block includes a second horizontal surface that is flush with the first horizontal surface and a fourth vertical surface that is parallel to the first vertical surface. The fourth vertical surface protrudes upward from the second horizontal surface.

[0010] A positioning block is fixedly attached to the third vertical surface. The positioning block includes a third horizontal surface that is flush with the first horizontal surface and a fifth vertical surface that is parallel to the third vertical surface, and the fifth vertical surface protrudes upward from the third horizontal surface.

[0011] The fourth vertical surface is attached to one side of the end frame, and the fifth vertical surface is attached to the other side of the end frame.

[0012] Preferably, the bottom surface of the contour block and the bottom surface of the positioning block are fitted and fixed to the assembly plane.

[0013] Preferably, the guide plate also includes a support block disposed on the side of the guide plate having the second vertical surface, the bottom surface of the support block being placed on the assembly plane, and the top surface of the support block being flush with the first horizontal plane.

[0014] Preferably, the number of contour blocks is at least two, and they are distributed along the length of the guide template, with the fourth vertical surface on the multiple contour blocks lying in the same plane.

[0015] Preferably, the end frame includes a cuboid profile with two upright plates on the first side and a flat surface on the second side. The flat surface is respectively attached to the first horizontal plane, the second horizontal plane, and the third horizontal plane. The first upright plate is located at the outer edge of the long side of the end frame. The outer surface of the first upright plate is attached to the fourth vertical plane. The short side of the end frame is attached to the fifth vertical plane.

[0016] Preferably, the system further includes pressure plates that press the end frame onto the guide template. The pressure plates are distributed on both sides of the guide template, and the pressure plates on both sides correspond to the positions of the leveling block and the support block, respectively, so as to press the flat surface of the end frame onto the first horizontal plane, the second horizontal plane, and the third horizontal plane.

[0017] Preferably, the pressure plate corresponding to the support block is pressed against the first surface, and a nylon plate that fits against the first surface is provided at the end of the pressure plate; the pressure plate corresponding to the equal height block is pressed against the first upright plate, and a limiting part extending into the end frame is provided on the pressure plate, the limiting part fitting against the inner plate surface of the first upright plate.

[0018] Preferably, the pressure plate is equipped with a double-ended stud, which is connected to the pressure plate and the fixing seat respectively, and is used to provide the pressure plate with a clamping force to press the end frame.

[0019] Preferably, the base plate and the fixing seat are fixedly mounted on the assembly platform.

[0020] Preferably, the guide template is fixedly connected to the base plate by bolts, the leveling block is fixedly connected to the guide template by bolts, and the positioning block is fixedly connected to the guide template by bolts.

[0021] Compared to the aforementioned background technology, this application supports the end frame using a guide template. The guide template's two parallel vertical surfaces and a third vertical surface perpendicular to these surfaces ensure the perpendicularity of the leveling blocks and positioning blocks, thus guaranteeing the end frame's external dimensions. This allows for the clamping of workpieces with unstable reference points and prone to deformation. Furthermore, with the auxiliary support provided by the leveling blocks and positioning blocks, the fourth vertical surface of the leveling blocks and the fifth vertical surface of the positioning blocks can also position the two vertical edges of the end frame, ensuring its positioning accuracy. This eliminates clamping errors and improves machining accuracy and efficiency. Attached Figure Description

It is used only for the convenience of describing this application and for simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] like Figures 1 to 3As shown, in this embodiment, a loading port end frame processing fixture is provided. The fixture includes a base plate 1, a guide template 2, a leveling block 3, and a positioning block 4. The base plate 1 serves as a reference plate, and the guide template 2, the leveling block 3, and the positioning block 4 are all fixedly mounted on the base plate 1.

[0047] Please refer to Figure 4 The base plate 1 has a reference surface 11 and an assembly plane 12. The reference surface 11 is in contact with the assembly platform 9 to ensure that the base plate 1 can be set on the assembly platform 9 with a stable reference surface 11. The assembly plane 12 is a horizontal plane parallel to the reference surface 11. The guide template 2 is fixed on the assembly plane 12, and the bottom surface of the guide template 2 can be in contact with the assembly plane 12 to ensure the assembly accuracy of the guide template 2.

[0048] Please refer to Figure 2 and Figure 5 The guide template 2 is a rectangular profile. The guide template 2 includes three vertical surfaces and one horizontal surface. The three vertical surfaces are defined as the first vertical surface 21, the second horizontal surface 31, and the third horizontal surface 41. The horizontal surface is defined as the first horizontal surface 24. The first vertical surface 21 and the second vertical surface 22 are two parallel opposite surfaces. The third vertical surface 23 is perpendicular to the first vertical surface 21 and the second vertical surface 22. The first horizontal surface 24 is located at the top of the guide template 2 and is perpendicular to the first vertical surface 21, the second vertical surface 22, and the third vertical surface 23.

[0049] Contour block 3 is L-shaped overall, please refer to... Figure 6 The leveling block 3 is fixed to the first vertical surface 21 on one side. The leveling block 3 includes a second horizontal surface 31 flush with the first horizontal surface 24 and a fourth vertical surface 32 parallel to the first vertical surface 21. The leveling block 3 is positioned by the first vertical surface 21 to ensure the assembly accuracy of the leveling block 3, thereby ensuring the parallelism of the first vertical surface 21 and the fourth vertical surface 32. It should be noted that the fourth vertical surface 32 protrudes upward from the second horizontal surface 31, and the second horizontal surface 31 is located between the fourth vertical surface 32 and the first vertical surface 21, thereby ensuring that the end frame can fit against the second horizontal surface 31 during clamping, ensuring positioning accuracy.

[0050] Positioning block 4 is fixedly attached to the third vertical surface 23. Please refer to [the documentation / reference]. Figure 7 and Figure 8 The positioning block 4 includes a third horizontal plane 41 that is flush with the first horizontal plane 24 and a fifth vertical plane 42 that is parallel to the third vertical plane 23. The positioning block 4 is positioned by the third vertical plane 23 to ensure the assembly accuracy of the positioning block 4, thereby ensuring the parallelism between the third vertical plane 23 and the fifth vertical plane 42. Furthermore, while ensuring the parallelism between the first vertical plane 21 and the fourth vertical plane 32, the perpendicularity between the fifth vertical plane 42 and the fourth vertical plane 32 can be ensured, thus ensuring the external dimensions of the end frame and enabling the clamping of workpieces with unstable reference points and easy deformation.

[0051] Based on this, the fourth vertical surface 32 is positioned in contact with one side of the end frame, and the fifth vertical surface 42 is positioned in contact with the other side of the end frame. The two sides of the end frame are perpendicular to each other, thereby achieving precise positioning of the end frame and ensuring clamping accuracy.

[0052] In summary, this application supports the end frame using the guide template 2. The guide template 2, with its two parallel vertical surfaces and a third vertical surface 23 perpendicular to the two vertical surfaces, ensures the perpendicularity of the leveling block 3 and the positioning block 4, thus guaranteeing the overall dimensions of the end frame. This allows for the clamping of workpieces with unstable reference points and prone to deformation. With the auxiliary support provided by the leveling block 3 and the positioning block 4, the fourth vertical surface 32 of the leveling block 3 and the fifth vertical surface 42 of the positioning block 4 can also position the two vertical edges of the end frame, ensuring its positioning accuracy. This eliminates clamping errors and improves machining accuracy and efficiency.

[0053] The bottom surfaces of the contour block 3 and the positioning block 4 are both fitted and fixed to the assembly plane 12 of the base plate 1, ensuring the vertical stability of the contour block 3 and the positioning block 4, thereby ensuring the positioning accuracy of the second horizontal plane 31 and the third horizontal plane 41, and further ensuring that the first horizontal plane 24, the second horizontal plane 31 and the third horizontal plane 41 are located in the same horizontal plane, thus improving the processing accuracy of the end frame.

[0054] The fixture also includes support block 6, please refer to Figure 11 and Figure 13 The support block 6 is located on one side of the guide template 2 with the second vertical surface 22. The bottom surface of the support block 6 rests on the assembly plane 12, and the top surface of the support block 6 is flush with the first horizontal plane 24. Together with the leveling block 3, it provides stable support for the end frames protruding from both sides of the guide template 2, ensuring the stability of the end frames. The support block 6 can also be fixedly attached to the second vertical surface 22, using a fixing method similar to that of the leveling block 3, to improve the stability of the support block 6. Details will not be elaborated here, but all of these methods fall within the scope of protection of this application.

[0055] Since the end frame has a certain length, in order to ensure that the leveling blocks 3 and the support blocks 6 can be effectively supported within the length range of the end frame, the number of leveling blocks 3 and support blocks 6 can be set to at least two, which can be set according to the actual situation. Multiple leveling blocks 3 and multiple support blocks 6 are distributed along the length direction of the guide template 2, and the fourth vertical surfaces 32 on multiple leveling blocks 3 are in the same plane, ensuring that multiple fourth vertical surfaces 32 can be stably supported on the side of the end frame.

[0056] Please refer to Figure 12The end frame includes a rectangular profile with two vertical plates on the first side and a flat surface on the second side. The rectangular profile is 860mm long and 126mm wide. The workpiece is relatively large and prone to deformation during clamping and processing. Therefore, the flat surface of the end frame is supported by multiple horizontal surfaces. For example, the flat surface is in contact with the first horizontal surface 24, the second horizontal surface 31, the third horizontal surface 41, and the top surface of the support block 6, thereby ensuring support and preventing deformation. The first vertical plate 01 is located on the outer edge of one long side of the end frame. The outer surface of the first vertical plate 01 can be in contact with the fourth vertical surface 32, while the short side of the end frame is in contact with the fifth vertical surface 42. This allows for precise positioning of the end frame using the leveling block 3 and the positioning block 4.

[0057] The fixture also includes a pressure plate 5 that presses the end frame onto the guide plate 2. Please refer to... Figure 9 , Figure 10 and Figure 13 The pressure plates 5 are distributed on both sides of the guide plate 2, and the pressure plates 5 on both sides correspond to the positions of the equal height block 3 and the support block 6, respectively, to avoid the end frame from deforming due to the clamping force of the pressure plates 5; through the clamping effect of the pressure plates 5, the flat surface of the end frame is pressed onto the first horizontal surface 24, the second horizontal surface 31, the third horizontal surface 41 and the top surface of the support block 6.

[0058] The pressure plate 5, corresponding to the support block 6, presses against the first surface of the end frame. The pressure plate 5 is generally rectangular, and a nylon plate 51, which fits against the first surface, is provided at the end of the pressure plate 5. Please refer to... Figure 9 This is to prevent wear and tear on the end frame caused by rigid contact. The pressure plate 5 corresponding to the equal-height block 3 presses against the first upright plate 01, and the pressure plate 5 is provided with a limiting part 52 extending into the end frame. Please refer to... Figure 10 The limiting part 52 is attached to the inner plate surface of the first vertical plate 01, thereby cooperating with the limiting effect of the fourth vertical surface 32 on the outer plate surface of the first vertical plate 01 to ensure the fixing effect of the end frame.

[0059] Please refer to Figure 13 Double-ended studs 8 are mounted on the pressure plate 5, and the double-ended studs 8 are connected to the pressure plate 5 and the fixed seat 7 respectively. The clamping force of the pressure plate 5 is adjusted by the cooperation of the double-ended bolts and nuts to ensure that the pressure plate 5 provides clamping force to press the end frame onto the fixture. The base plate 1 and the fixed seat 7 are both fixedly set on the assembly platform 9 to ensure the positioning accuracy of the base plate 1 and the fixed seat 7, thereby ensuring the positioning accuracy of the end frame.

[0060] The guide template 2 and the base plate 1 are fixedly connected by bolts, the leveling block 3 is fixedly connected to the guide template 2 by bolts, and the positioning block 4 is fixedly connected to the guide template 2 by bolts, ensuring a stable assembly effect. Furthermore, the fixing methods for the other components mentioned above can also be achieved using bolts; these will not be detailed here, but all fall within the scope of protection of this application.

[0061] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0062] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
