Description

Technical Field

[0001] This utility model relates to the field of measuring tooling technology, specifically to a general-purpose measuring tooling for aluminum alloy automotive parts. Background Technology

[0002] With the trend of lightweighting in automobiles and the rise of the new energy vehicle sector, aluminum alloy automotive parts have gradually replaced traditional iron parts. Automotive parts often have complex structural designs, posing significant challenges to production and testing. Taking the aluminum alloy steering knuckle as an example, as a core connecting component of the automotive chassis, it features irregular shapes and variable dimensions. Therefore, dimensional tolerance control of the steering knuckle is particularly important during the production process. Coordinate measuring machine (CMM) fixtures are the core tooling for controlling the dimensional measurement of parts, directly impacting the process control of product dimensions.

[0003] A search revealed that CN221364510U discloses a general-purpose measuring fixture for aluminum alloy automotive parts, relating to the field of aluminum alloy parts measurement technology. The fixture includes a base, on which a vertical plate is fixedly connected. On the side end face of the vertical plate, a fixed expansion sleeve and a sliding expansion sleeve are respectively provided corresponding to the machined holes of the workpiece to be measured. The fixed expansion sleeve is fixedly connected to the vertical plate, and the sliding expansion sleeve is slidably connected to the side end face of the vertical plate. The novel design eliminates the tedious steps of repetitive manual positioning, improving workpiece positioning efficiency. Simultaneously, it eliminates the influence of human interference on positioning accuracy, ensuring precision. The adjustable sliding expansion sleeve connects to the vertical plate, allowing the design to adapt to workpieces with different machining hole spacings for positioning and measurement, saving the cost of manufacturing different tooling. Furthermore, the design incorporates two sets of fixed and sliding expansion sleeves on the vertical plate, enabling simultaneous positioning and measurement of two workpieces, further enhancing workpiece measurement efficiency. However, its drawback lies in the fact that when fixing automotive parts, the expansion sleeve only works with the machining holes on the parts. When dealing with machining holes of different specifications, it cannot stably fix the parts, causing them to wobble and affecting measurement efficiency. Therefore, improving existing measuring tooling and designing a new universal measuring tooling for aluminum alloy automotive parts to address these technical shortcomings and improve the overall practicality of the measuring tooling is particularly important. Utility Model Content

The design of the limiting component allows it to adapt to automotive parts of different specifications. By adjusting the position and angle of the moving plate, parts of various shapes and sizes can be effectively limited. The friction strip on the outside of the moving plate and the deformation strip in the receiving groove increase the friction between the moving plate and the parts, ensuring the stability of the limiting and preventing the parts from shaking during measurement. The limiting component can be driven by the driving component without manual adjustment, simplifying the operation process and improving work efficiency. At the same time, the design of the driving component can stably drive the limiting component to operate, ensuring the accuracy and reliability of the measurement.

This design also simplifies the reset operation and improves work efficiency, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A universal measuring fixture for aluminum alloy automotive parts includes a base body, a vertical plate fixedly connected to the top of the base body, and movable blocks slidably connected to both ends of the vertical plate.

[0007] The limiting component is used to limit the movement of parts.

The connecting plate is fixedly connected to the top of the upright plate or the outside of the movable block. The fixed column is fixedly connected to the outside of the connecting plate. The movable sleeve is slidably connected to the outside of the fixed column. The multiple sets of connecting rods are rotatably connected to the four sides of both ends of the movable sleeve. The multiple sets of movable pieces are located around the four sides of the movable sleeve.

[0008] The driving component is used to drive the limit component to operate.

[0009] In a preferred embodiment of this utility model, the movable piece is connected to the movable sleeve via multiple sets of connecting rods, and the connecting rods and the movable piece are rotatably connected.

[0010] As a preferred embodiment of this utility model, a friction strip is fixedly connected to the outer side of the movable piece, and a receiving groove is formed inside the friction strip. Multiple sets of deformation strips are fixedly connected inside the receiving groove.

[0012] As a preferred embodiment of this utility model, the connecting plate has multiple sets of guide grooves inside, and the movable piece extends into the inside of the guide groove and is fixedly connected to a sliding block, the sliding block and the guide groove being slidably connected.

[0013] As a preferred embodiment of this utility model, two sets of guide wheels are rotatably connected to both sides of the sliding block, and the guide wheels are connected to both sides of the connecting plate.

[0014] As a preferred embodiment of this utility model, the driving assembly consists of a driving rod, a moving ring, a fixed ring, and a limiting ring.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this utility model, through the design of the limiting component, when it is necessary to limit the automotive parts, the moving sleeve is driven to slide on the fixed post by the driving component. The sliding of the moving sleeve drives multiple sets of connecting rods to move, thereby causing the moving piece to move accordingly. The moving piece achieves the limiting treatment of the parts through contact with the automotive parts. The design of the limiting component allows it to adapt to automotive parts of different specifications. By adjusting the position and angle of the moving piece, parts of various shapes and sizes can be effectively limited. The friction strip on the outside of the moving piece and the deformation strip in the receiving groove increase the friction between the moving piece and the parts, ensuring the stability of the limiting and preventing the parts from shaking during the measurement process. The limiting component can be driven by the driving component without manual adjustment, simplifying the operation process and improving work efficiency.

[0019] 2. In this utility model, through the design of the drive component, when the limiting component needs to be driven, the drive rod is pulled by external force, causing it to slide between the fixed column and the fixed ring. The sliding of the drive rod drives the moving sleeve to move, and then drives the moving piece to perform the limiting operation through the connecting rod. When it is necessary to release the component from the fixed position, the drive rod is pushed to contact the limiting ring, and the limiting ball and the limiting groove are connected to achieve the limiting, thereby keeping the moving sleeve in the reset position. The design of the drive component enables it to stably drive the limiting component to operate, ensuring the accuracy and reliability of the measurement. The design of the limiting ball and the limiting groove makes it easy to keep the drive rod in the reset position when the fixed position is released, preparing for the next measurement. At the same time, this design also simplifies the reset operation and improves work efficiency. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figures 1-4 This utility model provides a technical solution:

[0028] A general-purpose measuring fixture for aluminum alloy automotive parts includes a base body 1, a vertical plate 2 fixedly connected to the top of the base body 1, a movable block 3 slidably connected to both ends of the vertical plate 2, a limiting component 4 provided at both ends of the top of the vertical plate 2 and on the outer side of the movable block 3, and a driving component 5 provided on the outer side of the limiting component 4.

[0029] The limiting component 4 is used to limit the movement of parts. The limiting component 4 consists of a connecting plate 6, a fixed column 7, a movable sleeve 8, multiple sets of connecting rods 9 and multiple sets of movable pieces 10. The connecting plate 6 is fixedly connected to the top of the upright plate 2 or the outside of the movable block 3. The fixed column 7 is fixedly connected to the outside of the connecting plate 6. The movable sleeve 8 is slidably connected to the outside of the fixed column 7. The multiple sets of connecting rods 9 are rotatably connected to the four sides of both ends of the movable sleeve 8. The multiple sets of movable pieces 10 are located around the four sides of the movable sleeve 8.

[0030] The drive component 5 is used to drive the limit component 4 to operate.

[0031] Furthermore, the movable piece 10 is connected to the movable sleeve 8 via multiple sets of connecting rods 9. The connecting rods 9 and the movable piece 10 are rotatably connected. When the movable sleeve 8 moves, it drives the multiple sets of connecting rods 9 to move, so that the movable piece 10 can move.

[0032] The movable piece 10 is fixedly connected to a friction strip 11 on its outer side. The friction strip 11 has a receiving groove 12 inside. Multiple sets of deformation strips 13 are fixedly connected inside the receiving groove 12. The multiple sets of deformation strips 13 are evenly distributed inside the receiving groove 12. The outer side of the deformation strip 13 has a semi-circular structure design. When the movable piece 10 contacts the processing hole, the friction strip 11 can contact the processing hole, increasing the friction between the friction strip and the processing hole. At the same time, the deformation strip 13 contacts the inner wall of the processing hole, is squeezed and deformed, and fits the inner wall of the processing hole, thereby further increasing the friction between the friction strip and the processing hole, preventing loosening and affecting the fixing effect.

[0033] Secondly, the connecting plate 6 has multiple sets of guide grooves 14 inside. The movable piece 10 extends into the guide groove 14 and is fixedly connected to a sliding block 15. The sliding block 15 is slidably connected to the guide groove 14. Two sets of guide wheels 16 are rotatably connected to both sides of the sliding block 15. The guide wheels 16 are connected to both sides of the connecting plate 6. When the movable piece 10 moves, through the sliding connection with the guide groove 14 and in conjunction with the multiple sets of guide wheels 16, the guide groove 14 can guide the movable piece 10, thereby enabling the movable piece 10 to move stably.

[0034] Furthermore, the drive assembly 5 consists of a drive rod 17, a moving ring 18, a fixed ring 19, and a limiting ring 20. The drive rod 17 is fixedly connected to the inside of the moving sleeve 8, the moving ring 18 is fixedly connected to the outside of the drive rod 17, the fixed ring 19 is fixedly connected to the inside of the upright plate 2 or the moving block 3 and is located at the rear end of the drive rod 17, and the limiting ring 20 is fixedly connected to the inside of the upright plate 2 or the moving block 3 and is located at the front end of the drive rod 17. When it is necessary to fix the parts, the drive assembly 5 can drive the limiting assembly 4 to operate and fix the machining hole.

[0035] Furthermore, the drive rod 17 is slidably connected to the fixed column 7, and a compression spring 21 is fixedly connected to the outside of the moving ring 18 and the outside of the drive rod 17. The compression spring 21 is fixedly connected to the fixed ring 19, and the drive rod 17 is slidably connected to the fixed ring 19. The compression spring 21, in conjunction with the fixed ring 19, pulls the drive rod 17 to move, thereby causing the moving sleeve 8 to move, so that the connecting rod 9 can move.

[0036] Furthermore, the drive rod 17 and the limiting ring 20 are slidably connected. Multiple sets of limiting balls 22 are fixedly connected to the side of the moving ring 18 near the limiting ring 20. The limiting ring 20 is connected to the limiting balls 22 through the limiting groove 23. When it is necessary to release the parts, the displacement drive rod 17 moves the moving sleeve 8 away from the connecting plate 6, causing multiple sets of connecting rods 9 to reset, so that the moving piece 10 is reset. At the same time, the displacement of the drive rod 17 causes the moving ring 18 to move, so that the moving ring 18 contacts the limiting ring 20, so that the limiting balls 22 are moved into the inside of the limiting groove 23 and connected to the limiting ring 20 for limiting, thus limiting the drive rod 17 and making it convenient to remove the parts from the outside of the limiting assembly 4.

[0037] In this embodiment, the specific implementation scenario is as follows: In actual use, based on the position of the machining hole in the component, the machining hole is connected to the limiting component 4 by two sets of moving blocks 3. The compression spring 21, in conjunction with the fixing ring 19, pulls the drive rod 17 to move, causing the moving sleeve 8 to move, thus allowing the connecting rod 9 to move. When the moving sleeve 8 moves, it causes multiple sets of connecting rods 9 to move, allowing the moving piece 10 to move. When the moving piece 10 moves, through the sliding connection with the guide groove 14, in conjunction with multiple sets of guide wheels 16, the guide groove 14 can guide the moving piece 10, thereby enabling the moving piece 10 to move stably and contact the machining hole. When the moving piece 10 contacts the machining hole, the friction strip 11 can contact the machining hole, increasing the friction between the two. Force is applied, and the deformation strip 13 contacts the inner wall of the machining hole, deforms under pressure, and fits the inner wall of the machining hole, thereby further increasing the friction between the strip and the machining hole, preventing loosening and affecting the fixing effect. When it is necessary to release the parts, the displacement drive rod 17 moves the moving sleeve 8 away from the connecting plate 6, driving multiple sets of connecting rods 9 to reset, so that the moving piece 10 is reset. At the same time, the displacement of the drive rod 17 drives the moving ring 18 to move, bringing the moving ring 18 into contact with the limiting ring 20, so that the limiting ball 22 moves into the inside of the limiting groove 23 and makes a limiting connection with the limiting ring 20, limiting the drive rod 17, making it convenient to remove the parts from the outside of the limiting assembly 4. Compared with the existing measuring fixtures, this utility model can improve the overall practicality of the measuring fixture through design.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
