Description
Technical Field
[0001] This utility model relates to the field of parts inspection technology, specifically to a tooling for preventing errors in the inspection of automotive outer spacers. Background Technology
[0002] The outer ring spacer in automobiles is a critical precision component, typically a ring-shaped structure. Its unique design features an arched hole on one end face for lubrication or assembly, and a side hole not located at the axial center. The correct position of this side hole is generally defined as the end face furthest from the arched hole. This asymmetrical design places stringent requirements on the machining and assembly precision of the part.
[0003] Currently, during the manufacturing process of the outer spacer, there is a significant risk that the arched hole on the end face may be incorrectly machined closer to the side hole due to errors in equipment adjustment or human negligence. If this error occurs, the entire component may fail to be correctly positioned or malfunction during assembly, resulting in batch quality incidents and substantial economic losses.
[0004] In existing technologies, the inspection of this outer spacer ring mainly relies on manual methods. Operators use general measuring tools such as calipers and vernier calipers to measure two key dimensions: first, the distance from the circumferential edge of the side hole to the two end faces of the outer spacer ring, in order to indirectly determine the relative positional relationship between the side hole and the arched hole; second, whether the diameter of the side hole itself is within the tolerance range.
[0005] However, this traditional inspection method has many inherent defects: on the one hand, each part needs to be measured and read multiple times, which makes the inspection speed slow and the verification efficiency low; on the other hand, since the side hole is an arc surface, it is very difficult to find the measurement reference point using general measuring tools, resulting in large measurement errors and poor reliability. In addition, repetitive fine measurements can easily lead to visual and physical fatigue of operators, and the verification accuracy and efficiency will become even lower. Utility Model Content
[0006] To address the aforementioned shortcomings of existing technologies, this utility model provides an error-proof inspection fixture for automotive outer spacers. The outer spacer is fitted onto a positioning post, and the arched hole is inserted into a contour block. A person pushes a push rod to insert a gauge into the side hole. The position and diameter of the side hole are determined by the gauge insertion. This inspection method is quick and convenient, improving inspection efficiency and accuracy while reducing the labor intensity of personnel.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a tooling for inspecting and preventing errors in automotive outer spacers, wherein the outer spacer includes an arched hole and a side hole, and comprises a base, a fixing plate, a positioning post, a push rod, and a gauge. The fixing plate is fixedly disposed on one side of the upper surface of the base, and the positioning post is fixedly disposed on the other side of the upper surface of the base.

A limiting hole is provided on the fixing plate, the axis of the limiting hole and the axis of the positioning position are in the same plane and perpendicular to each other. The diameter of the push rod matches the inner diameter of the limiting hole. The gauge can slide axially in the limiting hole. It is fixedly installed at one end of the push rod near the positioning post and is on the same axis as the push rod. The gauge includes a fixed post, an upper limit post, and a lower limit post on the same axis. One end of the fixed post is fixedly connected to the end of the push rod near the positioning post, and the other end of the fixed post is fixedly connected to one end of the upper limit post. The other end of the upper limit post is fixedly connected to one end of the lower limit post. The diameter of the lower limit post is the lower limit of the side hole stop gauge, and the diameter of the upper limit post is the upper limit of the side hole stop gauge. The diameter of the fixed post is greater than the diameter of the upper limit post. The angle between the setting direction of the contour block and the axis of the gauge is the angle between the arched hole of the qualified outer spacer and the side hole.
[0008] Preferably, a handle is fixedly provided on the side of the push rod away from the positioning post, and a compression spring is sleeved on the push rod. One end of the compression spring is fixedly connected to the side wall of the fixing plate, and the other end is fixedly connected to the side wall of the handle.
[0009] Preferably, the side surface of the positioning post is provided with a cutting platform, the cutting platform faces the push rod, and the surface of the cutting platform is provided with an insertion hole, the insertion hole and the push rod are on the same axis.
[0010] Preferably, the end face of the fixed post corresponding to the push rod is provided with a threaded post, and the end face of the push rod corresponding to the fixed post is provided with a threaded hole, and the threaded post is screwed into the threaded hole.
[0011] Preferably, the fixed post, the upper limit post, and the lower limit post have a second chamfer at the end facing the positioning post.

Verification is performed by checking the gauge insertion status, simultaneously completing dual verification of the axial position and diameter of the side hole. This method provides highly reliable error-proof verification, is quick and convenient, and improves verification efficiency and accuracy. Furthermore, it eliminates the need for professional measurement knowledge, significantly reducing the workload and psychological burden on operators and effectively preventing errors and omissions caused by personnel fatigue or negligence. 2. In this utility model, a compression spring is provided between the handle and the fixed plate. After the calibration is performed by pushing the handle outwards by a spacer, the operator releases the handle, and the reaction of the compression spring quickly resets the push rod and gauge. This eliminates the need for manual removal, making the operation more convenient and improving calibration efficiency. Attached Figure Description

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.
[0019] like Figure 1-9 As shown, a tooling for inspecting and preventing errors in automotive outer spacers is disclosed. The outer spacer 11 includes an arched hole 17 and a side hole 12. The tooling includes a base 1, a fixing plate 2, a positioning post 3, a push rod 5, and a gauge. The fixing plate 2 is fixedly mounted on one side of the upper surface of the base 1, and the positioning post 3 is fixedly mounted on the other side of the upper surface of the base 1. The diameter of the positioning post 3 matches the inner diameter of the outer spacer 11, and a contour block 4 is provided at the bottom of the side surface of the positioning post 3. The contour block 4 matches the arched hole 17 of the outer spacer 11. A limiting hole 16 is provided on the fixing plate 2, and the axis of the limiting hole 16 is aligned with the axis of the fixed position. The push rod 5 is on the same plane and perpendicular to each other. Its diameter matches the inner diameter of the limiting hole 16 and it can slide axially within the limiting hole 16. The gauge is fixedly mounted on the end of the push rod 5 near the positioning post 3 and is on the same axis as the push rod 5. The gauge includes a fixed post 6, an upper limit post 7, and a lower limit post 8, all on the same axis. One end of the fixed post 6 is fixedly connected to the end of the push rod 5 near the positioning post 3, and the other end of the fixed post 6 is fixedly connected to one end of the upper limit post 7. The other end of the upper limit post 7 is fixedly connected to one end of the lower limit post 8. The diameter of the lower limit post 8 is the diameter of the side hole 12. The lower limit of the stop gauge and the upper limit of the gauge rod 7 have the same diameter as the upper limit of the side hole 12 stop gauge. The diameter of the fixed column 6 is greater than the diameter of the upper limit column 7. The angle between the setting direction of the contour block 4 and the axis of the gauge is the angle between the arched hole 17 of the qualified outer spacer 11 and the side hole 12. A handle 9 is fixedly installed on the side of the push rod 5 away from the positioning column 3. A compression spring 10 is sleeved on the push rod 5. One end of the compression spring 10 is fixedly connected to the side wall of the fixed plate 2, and the other end is fixedly connected to the side wall of the handle 9. A cutting table 13 is provided on the side surface of the positioning column 3. The cutting table 13 faces the push rod 5. The surface of the cutting table 13... The mounting post 6 has an insertion hole 20, which is coaxial with the push rod 5. The mounting post 6 has a threaded post 19 on the end face of the push rod 5, and the push rod 5 has a threaded hole 18 on the end face of the mounting post 6. The threaded post 19 is screwed into the threaded hole 18. The mounting post 6, the upper limit post 7, and the lower limit post 8 have a second chamfer 15 on one end facing the positioning post 3. The upper end of the positioning post 3 has a first chamfer 14. The side surfaces of the upper limit post 7, the mounting post 6, and the lower limit post 8 are painted with different colors. The positioning post 3 and the mounting plate 2 are fixedly connected to the base 1 by screws.
[0020] The detailed connection means thereof are well-known techniques in the art, and the following mainly introduces the working principle and process, which are specifically as follows: According to the description drawings Figure 1-9 It can be known that when the utility model works, the base 1 is placed on a flat table surface, an operator sleeves the outer spacer ring 11 on the positioning position with the arched hole 17 facing downward at the same time, and inserts it onto the profiling block 4. Since the diameter of the positioning post 3 matches the inner diameter of the outer spacer ring 11, and the profiling block 4 matches the arched hole 17 of the outer spacer ring 11, the stability of the outer spacer ring 11 can be ensured. The operator pushes the push rod 5 by hand, the push rod 5 and the gauge move axially toward the side hole 12 of the outer spacer ring 11. Since the diameter of the push rod 5 matches the inner diameter of the limiting hole 16, the axial movement of the push rod 5 can be ensured to be stable without shaking. The push rod 5 and the gauge move until they are resisted and stop moving, and whether the side hole 12 is qualified is judged according to the insertion condition of the gauge into the side hole 12. Since the diameter of the lower limit cylinder 8 is the lower limit of the no-go gauge for the side hole 12, the diameter of the upper limit cylinder 7 is the upper limit of the no-go gauge for the side hole 12, and the included angle between the arrangement direction of the profiling block 4 and the axis of the gauge is the included angle between the arched hole 17 and the side hole 12 of a qualified outer spacer ring 11, therefore, the specific judgment is as follows: if the lower limit cylinder 8 cannot be inserted into the side hole 12, it indicates that the actual aperture of the side hole 12 is smaller than the lower limit of the no-go gauge for the side hole 12 or the position of the side hole 12 is wrong, so it is judged as unqualified; if both the lower limit cylinder 8 and the upper limit cylinder 7 can be inserted into the side hole 12, it indicates that although the position is correct, the actual aperture of the side hole 12 is larger than the upper limit of the no-go gauge for the side hole 12, so it is also judged as unqualified, if Figure 8 and Figure 9 ; if the lower limit cylinder 8 can be inserted into the side hole 12, and the upper limit cylinder 7 cannot be inserted into the side hole 12, it indicates that the actual aperture of the side hole 12 is between the upper limit and the lower limit of the no-go gauge, and the position is correct, so it is judged as qualified, as shown in Figure 6 and Figure 7 ; it should be noted here that the situation where the actual inner diameter of the side hole 12 is equal to the upper limit cylinder 7 and the upper limit of the no-go gauge for the side hole 12 can be ignored, because the probability of this situation is low. If this situation must be considered, the diameter of the upper limit cylinder 7 can be made slightly larger than the upper limit of the no-go gauge for the side hole 12. For example, if the no-go gauge for the side hole 12 is 10±0.1mm, the diameter of the upper limit cylinder 7 can be made 10.11mm, so that when the actual aperture of the side hole 12 is equal to the upper limit of the no-go gauge or the lower limit of the no-go gauge, it can also be judged as qualified. The outer spacer ring 11 is checked in the above manner, and qualified products and unqualified products are sorted. The utility model realizes positioning through the positioning post 3 and the profiling block 4, and performs checking according to the insertion condition of the gauge, and completes the double checking of the axial position and the aperture size of the side hole 12 synchronously. The error-proof checking effect has high reliability, the checking method is fast and convenient, the checking efficiency and accuracy are improved. Meanwhile, professional measurement knowledge is not required, which greatly reduces the labor intensity and psychological burden of operators, and effectively avoids wrong detection and missed detection caused by personnel fatigue and negligence.
[0021] A handle 9 is fixedly installed on the side of the push rod 5 away from the positioning post 3. A compression spring 10 is sleeved on the push rod 5. One end of the compression spring 10 is fixedly connected to the side wall of the fixing plate 2, and the other end is fixedly connected to the side wall of the handle 9. After calibration, when the operator releases the handle, the reaction force of the compression spring 10 quickly resets the push rod 5 and the gauge, eliminating the need for manual removal and improving calibration efficiency.
[0022] The positioning post 3 has a cutting platform 13 on its side surface, facing the push rod 5. The cutting platform 13 has an insertion hole 20 on its surface, which is coaxial with the push rod 5 to ensure the depth of gauge insertion. This allows for the extension of the upper limit post 7 and lower limit post 8 in the gauge, making it easier for personnel to check the insertion status. Alternatively, the side surfaces of the fixed post 6, upper limit post 7, and lower limit post 8 can be painted with different colors. After insertion, the color can be used for intuitive judgment. For example, if the fixed post 6 and lower limit post 8 are painted red, and the upper limit post 7 is painted green, then if the moving rod stops moving and the area near the outer spacer 11 is red, it means the lower limit post 8 is not inserted, or both the lower limit post 8 and upper limit post 7 are inserted, which is unqualified. If the area near the outer spacer 11 is green, it means the lower limit post 8 is inserted, but the upper limit post 7 is not inserted and is exposed, which is qualified.
[0023] The fixed post 6 has a threaded post 19 on the end face corresponding to the push rod 5, and the push rod 5 has a threaded hole 18 on the end face corresponding to the fixed post 6. The threaded post 19 is screwed into the threaded hole 18. This allows for the replacement of gauges of different diameters and the measurement of the side holes 12 of different outer spacers 11, improving applicability. Similarly, the positioning post 3 and the fixing plate 2 are fixedly connected to the base 1 by screws and can also be disassembled and replaced to accommodate different outer spacers 11.
[0024] The fixing post 6, the upper limit post 7, and the lower limit post 8 have a second chamfer 15 at one end facing the positioning post 3 to prevent the edges from being too sharp and damaging the surface of the outer spacer 11. At the same time, this facilitates the insertion of the upper limit post 7 and the lower limit post 8 into the side hole 12. Similarly, the upper end of the positioning post 3 has a first chamfer 14 to facilitate the fitting of the outer spacer 11 and to avoid damaging the outer spacer 11.
[0025] 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.
