Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a tooling for manufacturing automotive parts that is easy to adjust. Background Technology

[0002] Tooling for automotive parts manufacturing refers to auxiliary equipment such as tools used in automotive parts production to ensure machining accuracy, improve production efficiency, and meet specific process requirements. The use of such tooling, which is easy to adjust, is necessary to adapt to the diverse production needs such as differences in parts for different car models and design changes. It can reduce tooling changeover time, optimize machining processes to improve production efficiency, reduce tooling inventory and replacement costs, and extend the service life of tooling.

[0003] Tooling, also known as process equipment, refers to the general term for various tools, equipment, fixtures, molds, measuring instruments, etc., provided to realize the production and manufacturing process of a product. Inspection gauges, as tools used to inspect the size, shape, and positional accuracy of automotive parts, play a crucial role in quality control during automotive parts manufacturing; therefore, inspection gauges are part of the tooling. Specific types of inspection gauges include go / no-go gauges, measuring instruments, coordinate measuring machines (CMMs), and profilometers. Go / no-go gauges are used to check whether the dimensions of parts, such as the diameter of holes and the width of grooves, are within the allowable range. A go gauge is used to check the lower limit of a dimension; if it passes smoothly, it indicates that the dimension is not less than the lower limit value. A no-go gauge is used to check the upper limit of a dimension; if it cannot pass, it indicates that the dimension is not greater than the upper limit value.

[0004] Existing go / no-go gauges are often designed for specific dimensional ranges, and one type of go / no-go gauge can only be used to inspect one or a few parts with similar dimensions. In the production of automotive engine parts, the dimensions of the same type of parts in different engine models may vary slightly. Existing go / no-go gauges cannot quickly adapt to such dimensional changes, requiring frequent replacement of different specifications of go / no-go gauges, which affects production efficiency. Therefore, a tooling for automotive parts manufacturing that is easy to adjust is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an easily adjustable tooling for manufacturing automotive parts, aiming to improve the problem that the existing go / no-go gauges cannot be adapted to various parts during use, resulting in a significant decrease in the practicality and production efficiency of the go / no-go gauges.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tooling for manufacturing automotive parts that is easy to adjust, comprising a main connecting rod, a secondary rod one at one end of the main connecting rod, and a secondary rod two at the other end of the main connecting rod. Bolts are fixedly connected to one side of the outer wall of both secondary rod one and secondary rod two, and the outer walls of the bolts are threaded into the inside of the main connecting rod. A stop end is provided on one side of secondary rod one, and a through end is provided on one side of secondary rod two. Rotating components for switching between different sizes of through ends are installed on one side of the inside of both secondary rod one and secondary rod two.

[0007] The rotating assembly includes a limiting sleeve, the upper side of the outer wall of the limiting sleeve is rotatably connected to one side of the inner side of the secondary rod, a connecting sleeve is fixedly connected to the lower surface of the limiting sleeve, a locking tooth is fixedly connected to the lower surface of the connecting sleeve, a connecting plate is provided on the side away from the connecting sleeve, and a locking assembly for fixing the position of the locking tooth is installed inside the connecting sleeve.

[0008] Furthermore, the locking assembly includes a pressing rod, the outer wall of which is slidably connected to the inside of the connecting sleeve, a toothed cylinder is fixedly connected to the lower surface of the pressing rod, and a spring is fixedly connected to the lower surface of the toothed cylinder, the spring engaging with the engaging teeth.

[0009] Furthermore, a limiting block is fixedly connected to one side of the inner wall of the connecting plate, a mounting shell is slidably connected to the outer wall of the connecting plate, an inclined block is slidably connected to the inner wall of the connecting plate, a locking block is fixedly connected to one side of the outer wall of the inclined block, and the outer wall of the locking block penetrates the connecting plate and is slidably connected to the inner wall of the mounting shell.

[0010] Furthermore, a second spring is fixedly connected to one side of the inner wall of the connecting plate, a trapezoidal block is fixedly connected to one end of the second spring, and an ejector rod is fixedly connected to one side of the outer wall of the trapezoidal block. The outer wall of the ejector rod is inserted through the inside of the connecting plate.

[0011] Furthermore, the outer wall of the main connecting rod is fixedly connected with multiple anti-slip patterns, which are used to increase the friction between the hand and the main connecting rod.

[0012] Furthermore, the outer wall of the pressing rod is slidably connected to the upper side of the inner side of the secondary rod, and the pressing rod is used to push the toothed cylinder to move.

[0013] Furthermore, one end of the spring is fixedly connected to the lower side of the inner wall of the secondary rod, and the spring is used to push the toothed cylinder to engage with the toothed engagement.

[0014] Furthermore, a connecting piece is fixedly connected to one side of the outer wall of the connecting sleeve, and one side of the outer wall of the connecting piece is fixedly connected to one side of the outer wall of the connecting plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, pressing the pressing rod causes the toothed cylinder to squeeze the spring, thereby disengaging from the outer wall of the engaging teeth, allowing the connecting plate to rotate. After the connecting plate rotates, different models of stop and through ends can be installed and adjusted. At the same time, by rotating the auxiliary rod one or auxiliary rod two, the length of the main connecting rod can be adjusted, thereby improving the practicality of the tooling.

[0017] 2. In this utility model, by pressing the inclined block, the inclined block is limited to move on the outer wall of the limiting block, thereby driving the locking block to disengage from the inside of the mounting shell, thus achieving the effect of facilitating quick replacement of the stop end and the through end. At the same time, by moving the inclined block, the spring is stretched to push the ejector rod to move. At this time, by moving the ejector rod, the mounting shell is automatically disassembled, thereby improving the practicality of the tooling. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 - Figure 5This utility model provides an embodiment of a tooling for manufacturing automotive parts that is easy to adjust. It includes a main connecting rod 1, which serves as the primary connecting component, connecting secondary rod 2 and secondary rod 3, thus ensuring the overall integrity of the tooling structure. Secondary rod 2 is located at one end of the main connecting rod 1, used to install components such as a stop end 5, participating in the inspection or processing of automotive parts. Secondary rod 3 is located at the other end of the main connecting rod 1, used to install components such as a through end 6, working in conjunction with secondary rod 2. Bolts 4 are fixedly connected to one side of the outer wall of both secondary rod 2 and secondary rod 3. The outer walls of the bolts 4 are threaded into the inside of the main connecting rod 1, and the bolts 4 are used to connect secondary rod 2 and secondary rod 3. 3. The connection and fixation with the main connecting rod 1, and the threaded connection allows for easy adjustment of the positions of the auxiliary rod 1 2 and auxiliary rod 2 3 on the main connecting rod 1, thereby realizing the initial adjustment function of the tooling to adapt to the inspection or processing needs of automotive parts of different sizes. A stop end 5 is provided on one side of the auxiliary rod 1 2, which is used to limit or operate one extreme position of the automotive part during inspection or processing. A through end 6 is provided on one side of the auxiliary rod 2 3, which is used to inspect or operate another related position of the automotive part, cooperating with the stop end 5 to achieve the corresponding function. A rotating assembly 7 for switching between different sizes of through ends 6 is installed on one side inside both the auxiliary rod 1 2 and the auxiliary rod 2 3; the limiting sleeve 701 in the rotating assembly 7... The upper side of the outer wall is rotatably connected to one side of the inner side of the secondary rod 3. The limiting sleeve 701 provides a base for the installation and rotation of components such as the connecting sleeve 702, allowing the connecting sleeve 702 to rotate relative to the secondary rod 3, thereby realizing the switching operation of the through end 6. The connecting sleeve 702 is fixedly connected to the lower surface of the limiting sleeve 701. The connecting sleeve 702 is used to connect components such as the engaging tooth 703, combining the relevant components together to realize functions such as rotation and positioning. The engaging tooth 703 is fixedly connected to the lower surface of the connecting sleeve 702. The engaging tooth 703 plays a key role in the rotation and positioning process, and achieves fixation and switching at different positions through cooperation with other components. A connecting plate 704 is provided on the side away from the connecting sleeve 702. It may be used to connect other related structures or components to jointly complete the function of the rotating component 7. The connecting sleeve 702 is equipped with a locking component 8 for fixing the position of the engaging tooth 703. The outer wall of the pressing rod 802 in the locking component 8 is slidably connected to the inside of the connecting sleeve 702. The pressing rod 802 is used to receive external operating force. When the pressing rod 802 is pressed, it can drive the toothed cylinder 801 and other components to perform corresponding actions. The toothed cylinder 801 is fixedly connected to the lower surface of the pressing rod 802. The toothed cylinder 801 locks and unlocks the position of the engaging tooth 703 by cooperating with the engaging tooth 703. When the toothed cylinder 801 meshes with the engaging tooth 703, the engaging tooth 703 is fixed, thereby fixing the position of the through end 6.When the toothed cylinder 801 separates from the engaging tooth 703, the engaging tooth 703 can rotate to switch the through end 6. A spring 803 is fixedly connected to the lower surface of the toothed cylinder 801. The spring 803 is used to provide restoring force. When the pressing rod 802 is pressed to separate the toothed cylinder 801 from the engaging tooth 703, the pressing rod 802 is released. The spring 803 will push the toothed cylinder 801 to move upward, so that the toothed cylinder 801 re-engages with the engaging tooth 703 and returns to the locked state, ensuring the positional stability of the through end 6 during the working process.

[0028] Reference Figure 5 and Figure 6A limiting block 10 is fixedly connected to one side of the inner wall of the connecting plate 704. The limiting block 10 is used to limit the inclined block 12 inside the connecting plate 704 to prevent it from moving excessively or deviating from the predetermined motion track, thus ensuring the accuracy and stability of the component's movement. A mounting shell 11 is slidably connected to the outer wall of the connecting plate 704. The mounting shell 11 provides space for the installation and sliding of the locking block 13, and also provides a certain degree of protection for the internal components. Furthermore, the sliding connection between the mounting shell 11 and the connecting plate 704 facilitates related operations and adjustments. An inclined block 12 is slidably connected to the inner wall of the connecting plate 704. When subjected to a certain external force, the inclined block 12 can slide on the inner wall of the connecting plate 704. Its sliding will drive the associated locking block 13 to move, thereby achieving a specific function. Yes, for example, it plays a key transmission role in the adjustment or fixing of tooling. A locking block 13 is fixedly connected to one side of the outer wall of the inclined block 12. The outer wall of the locking block 13 penetrates the connecting plate 704 and is slidably connected to the inner wall of the mounting shell 11. The locking block 13 can cooperate or engage with the external structure through the sliding connection with the inner wall of the mounting shell 11. It plays a connecting and positioning role in the assembly, fixing or adjustment of tooling, ensuring that the connection between the various parts of the tooling is tight and the position is accurate. A second spring 14 is fixedly connected to one side of the inner wall of the connecting plate 704. A trapezoidal block 15 is fixedly connected to one end of the second spring 14. The second spring 14 is used to provide elastic force to the trapezoidal block 15. When the trapezoidal block 15 is subjected to external force, the second spring 14 can generate corresponding deformation and restoring force, so that the trapezoidal block 15 is subjected to external force. The trapezoidal block 15 can move within a certain range and return to its initial position. During the operation of the tooling, it may serve as a buffer, reset, or assist in the movement of other components. A push-out rod 16 is fixedly connected to one side of the outer wall of the trapezoidal block 15. The outer wall of the push-out rod 16 penetrates the interior of the connecting plate 704. The push-out rod 16 can move under the influence of the trapezoidal block 15, and its function may be to push or push other components under specific circumstances. Multiple anti-slip patterns 9 are fixedly connected to the outer wall of the main connecting rod 1. These patterns increase the friction between the hand and the main connecting rod 1. When the operator holds the main connecting rod 1 to operate, adjust, or use the tooling, the anti-slip patterns 9 effectively prevent hand slippage, improving operational stability and safety, and ensuring the tooling can be accurately... To ensure accurate operation and avoid operational errors or tooling misalignment caused by hand slippage, the pressing rod 802 is slidably connected to the upper inner side of the secondary rod 3. As mentioned earlier, the pressing rod 802 is used to push the toothed cylinder 801 to move. Its sliding connection to the upper inner side of the secondary rod 3 allows the operator to easily press it from the outside. This connection also ensures the directionality and stability of the pressing rod 802's movement, enabling it to accurately transmit force to the toothed cylinder 801 and control its position. One end of the spring 803 is fixedly connected to the lower inner wall of the secondary rod 3. The spring 803 is used to push the toothed cylinder 801 to engage with the engaging teeth 703. Through its connection to the lower inner wall of the secondary rod 3...After the retaining sleeve 801 separates from the engaging tooth 703, the spring 803 uses its own elastic restoring force to push the retaining sleeve 801 upwards, causing it to re-engage with the engaging tooth 703. This ensures that the engaging tooth 703 remains in a fixed position during operation, thereby locking the position of the through end 6 and ensuring the stability and reliability of the tooling during use. A connecting piece 17 is fixedly connected to one side of the outer wall of the connecting sleeve 702. The outer wall of the connecting piece 17 is fixedly connected to one side of the outer wall of the connecting plate 704. The connecting piece 17 connects the connecting sleeve 702 and the connecting plate 704, forming a relatively stable structure between them. During the operation of the rotating assembly 7, the connecting piece 17 can transmit the movement or force of the connecting sleeve 702 to the connecting plate 704, or vice versa, achieving coordinated work between the two and ensuring that the rotating assembly 7 can smoothly perform functions such as switching and fixing the through end 6.

[0029] Working principle: When it is necessary to inspect the bore diameter of automotive parts, firstly, by rotating the auxiliary rod 1 2 or auxiliary rod 2 3, the bolts 4 at both ends are rotated inside the main connecting rod 1, thereby achieving the effect of adjusting the length of the main connecting rod 1 according to the user. When it is necessary to inspect different models of parts, by pressing the pressing rod 802, the toothed cylinder 801 is squeezed, thereby achieving the effect of pulling the spring 1 803 away from the outer wall of the engaging tooth 703. At this time, by rotating the connecting plate 704, the connecting piece 17 can be adjusted by multiple connecting plates 704. After switching the connecting plate 704, the pressing rod 802 is released, causing the spring 1 803 to push the toothed cylinder 801 to engage the engaging tooth 703, thereby achieving the effect of fixing the connecting plate 704. By rotating the connecting plate 704, the effect of quickly adjusting the stop end 5 and the through end 6 of different models can be achieved.

[0030] Secondly, when the connecting plate 704 is adjusted and the stop end 5 or the through end 6 needs to be replaced, the inclined block 12 is pressed to make it slide on the outer wall of the limiting block 10, thereby driving the locking block 13 to disengage from the mounting shell 11. Then, the movement of the inclined block 12 drives the trapezoidal block 15 to stretch the spring 14. The movement of the trapezoidal block 15 pushes the ejector rod 16 to move. The movement of the ejector rod 16 then achieves the effect of automatically disassembling the mounting shell 11.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
