Description

Technical Field

[0001] This utility model relates to the field of automotive inspection tools, and more specifically, to a transmission mount assembly inspection tool. Background Technology

[0002] While maintaining constant part tolerances, one approach is to increase machining accuracy to ensure 100% dimensional compliance, but this increases machining costs. Alternatively, machining accuracy can be appropriately reduced to lower costs. This requires monitoring part dimensions and tolerances to ensure they meet design requirements. For parts produced in small batches, a coordinate measuring machine (CMM) can be used to inspect the geometric dimensions and tolerances.

[0003] For mass-produced parts, specialized inspection tools, known as jigs, are required. Automotive jigs are specialized inspection tools used to check whether the characteristics of automotive parts conform to design standards; they are non-standard, customized products.

[0004] Currently, different types of inspection tools are designed for different parts. There are tools for inspecting single dimensions, such as go / no-go gauges and thread gauges for qualitatively checking whether the hole diameter is within the tolerance range. For most assembly parts, in order to improve inspection efficiency, it is necessary to design dedicated comprehensive inspection tools to qualitatively inspect the accuracy of all dimensions of the assembly at one time, and to determine whether the assembly parts are qualified by using the inspection tools. However, existing inspection tools can only inspect the dimensions of the brackets and support arms before assembly, and cannot inspect the dimensional accuracy of the relative position of the support arms and brackets on the assembly after the transmission mount assembly is assembled. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model proposes a transmission mount assembly inspection tool that can complete the inspection of the mounting hole position of the transmission mount assembly in one go, so as to determine whether the dimensional accuracy of the relative position of the transmission mount support arm and the bracket is qualified, which greatly improves work efficiency.

[0006] To achieve the above objectives, this solution provides a transmission mount assembly inspection fixture, including a base, a clamping mechanism, and a positioning detection mechanism. The clamping mechanism is disposed on the base and is used to clamp the transmission mount assembly. The positioning detection mechanism is fixed on the base and has multiple positioning pins slidably connected to it. The dimensions between each positioning pin are equal to the assembly dimensions between each mounting hole of the transmission mount assembly.

[0007] In this technical solution, the transmission mount assembly includes a transmission mount bracket and a transmission mount arm support. During testing, the transmission mount bracket and transmission mount arm support are assembled as a whole and placed on a positioning and testing mechanism. Then, the clamping mechanism clamps and fixes both sides of the transmission mount bracket. If multiple positioning pins can be inserted into the mounting holes of the transmission mount assembly, the mounting hole position of the transmission mount assembly is qualified. In this way, the mounting hole position of the transmission mount assembly can be tested at one time to determine whether the dimensional accuracy of the relative position of the transmission mount arm and the bracket is qualified. The testing efficiency is high and batch testing of the transmission mount assembly can be realized.

[0008] As a preferred embodiment, the clamping mechanism includes a first support column, a second support column, and two clamping structures disposed on the base. The two clamping structures cooperate with the first support column and the second support column respectively to clamp both sides of the transmission mount assembly. The first support column and the second support column respectively support the bottom of both sides of the clamping transmission mount bracket. The two clamping structures work together to press the two sides of the clamping transmission mount assembly together, thereby completing the fixation of the clamping transmission mount assembly.

[0009] As a preferred embodiment, the clamping structure includes a mounting bracket, grippers, a connecting rod, and a handle. The mounting bracket is fixed to the base. The grippers and the handle are rotatably connected to the top of the mounting bracket. One end of the connecting rod is rotatably connected to the handle, and the other end of the connecting rod is rotatably connected to the grippers. The grippers are used to press the transmission mount assembly. When the handle is flipped upward, the handle drives the connecting rod to press down the grippers connected to the other end of the connecting rod, thereby pressing both sides of the transmission mount assembly against the first support post or the second support post.

[0010] As a preferred embodiment, the top of the first support column is provided with a cylindrical structure that is adapted to the mounting holes of the transmission mount assembly, and the top of the second support column is provided with a prism structure for detecting the tolerance of the mounting holes of the transmission mount assembly. During installation, the cylindrical structure is used for positioning first, the mounting hole on one side of the transmission mount bracket is fitted into the cylindrical structure, and then the mounting hole on the other side of the transmission mount bracket is fitted into the fixed prism structure. Since the size of the prism structure is slightly smaller than the size of the cylindrical structure, the prism structure can absorb the accumulated tolerance.

[0011] As a preferred embodiment, the positioning detection mechanism includes a third support frame and a fourth support frame. The third support frame abuts against the bottom of the transmission suspension arm support, and the fourth support frame abuts against the top of the transmission suspension bracket. The third and fourth support frames are respectively provided with multiple positioning holes corresponding to the mounting holes of the transmission suspension bracket and the transmission suspension arm support. One end of each positioning detection pin passes through each positioning hole and is inserted into each mounting hole of the transmission suspension assembly. The third support frame is adapted to the position of the transmission suspension arm support, and the fourth support frame is adapted to the position of the transmission suspension bracket.

[0012] As a preferred embodiment, in order to detect the position of the wiring harness fixing hole of the transmission mount assembly, a flip frame is rotatably connected to the top of the fourth support frame. The fourth support frame and the flip frame are fixed by fasteners. The flip frame is provided with positioning holes corresponding to the position of the wiring harness fixing hole of the transmission mount assembly. One end of the positioning inspection pin passes through each of the positioning holes and is inserted into the mounting holes of the transmission mount bracket and the transmission mount arm support. If the positioning inspection pin can be smoothly inserted into the wiring harness fixing hole of the transmission mount assembly, it indicates that the part is qualified.

[0013] As a preferred embodiment, a go / no-go gauge detachably connected to the base is also included, the go / no-go gauge being used to detect the mounting hole dimensions of the transmission mount assembly.

[0014] As a preferred embodiment, to facilitate the removal and storage of the go / no-go gauge, the base is provided with a first mounting seat, and the go / no-go gauge is inserted into the first mounting seat.

[0015] As a preferred embodiment, the device also includes a handheld inspection block detachably connected to the base. One side of the handheld inspection block is provided with a hole diameter inspection pin corresponding to the position of the transmission suspension arm support mounting hole. After the positioning and inspection of the transmission suspension arm support mounting hole is completed, the transmission suspension arm support can be picked up separately, and then the hole diameter of the transmission suspension arm support mounting hole can be inspected using the handheld inspection block.

[0016] As a preferred embodiment, to facilitate the removal and storage of the handheld inspection block, the base is provided with a second mounting seat, and the handheld inspection block is engaged with the second mounting seat.

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

[0018] 1. The present invention provides a transmission mount assembly inspection fixture that clamps and fixes both sides of the transmission mount assembly through a clamping mechanism. The multiple positioning pins on the positioning detection mechanism correspond to the positions of the mounting holes of the transmission mount assembly. The accuracy of the position of the mounting holes of the transmission mount assembly can be determined by whether the multiple positioning pins are inserted into place, resulting in high detection efficiency.

[0019] 2. By integrating the clamping mechanism, positioning detection mechanism, positioning inspection pin, go / no-go gauge, and handheld inspection block into one unit, it can complete the one-time inspection of the position, size, and height of the transmission mount assembly mounting holes. It has high inspection efficiency and is suitable for the installation accuracy inspection of batch transmission mount assemblies. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0029] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0030] Example 1:

[0031] like Figure 1-4 As shown, this embodiment provides a transmission mount assembly inspection fixture, including a base 1, a clamping mechanism and a positioning detection mechanism. The clamping mechanism is disposed on the base 1 and is used to clamp the transmission mount assembly 8. The positioning detection mechanism is fixed on the base 1, and a plurality of positioning inspection pins 3 are slidably connected on the positioning detection mechanism. The dimensions between each positioning inspection pin 3 are respectively equal to the assembly dimensions between each mounting hole of the transmission mount assembly 8.

[0032] In this embodiment, as Figure 6 As shown, the transmission mount assembly 8 consists of a transmission mount bracket 81 and a transmission mount arm support 82. During testing, the transmission mount bracket 81 and the transmission mount arm support 82 are first assembled to form the transmission mount assembly 8, and then the transmission mount assembly 8 is placed in the transmission mount assembly inspection fixture for testing.

[0033] Specifically, the clamping mechanism includes a first support column 11, a second support column 12 and two clamping structures 2 disposed on the base 1. The two clamping structures 2 cooperate with the first support column 11 and the second support column 12 respectively to clamp the two sides of the transmission suspension assembly 8.

[0034] In this embodiment, the first support column 11 and the second support column 12 respectively support and clamp the two sides of the transmission suspension bracket 81, and the two clamping structures 2 are respectively used to press the two sides of the transmission suspension bracket 81 onto the first support column 11 and the second support column 12.

[0035] Specifically, the clamping structure 2 includes a mounting frame 21, a gripper 22, a connecting rod 23, and a handle 24. The mounting frame 21 is fixed to the base 1. The gripper 22 and the handle 24 are rotatably connected to the top of the mounting frame 21. One end of the connecting rod 23 is rotatably connected to the handle 24, and the other end of the connecting rod 23 is rotatably connected to the gripper 22.

[0036] In this embodiment, when the handle 24 is flipped upward, the handle 24 drives the connecting rod 23 to press down and fix the jaw 22 at the other end of the connecting rod 23; when the handle 24 is flipped downward, the handle drives the connecting rod 23 to lift up and release the jaw 22 at the other end of the connecting rod 23.

[0037] Specifically, the top of the first support column 11 is provided with a cylindrical structure 111 that is adapted to the mounting hole of the transmission mount assembly 8, and the top of the second support column 12 is provided with a prism structure 121 for detecting the tolerance of the mounting hole of the transmission mount assembly 8.

[0038] In this embodiment, the cylindrical structure 111 and the prism structure 121 are respectively adapted to the mounting hole positions on both sides of the transmission mount bracket 81. The outer diameter of the prism structure 121 is slightly smaller than the outer diameter of the cylindrical structure 111. During testing, the mounting hole on one side of the transmission mount bracket 81 is first matched with the cylindrical structure 111 and positioned. Then, the mounting hole on the other side of the transmission mount bracket 81 is matched with the prism structure 121 to absorb the cumulative tolerance of the transmission mount bracket 81.

[0039] Specifically, the positioning detection mechanism includes a third support frame 13 and a fourth support frame 14. The third support frame 13 abuts against the bottom of the transmission suspension arm support 82, and the fourth support frame 14 abuts against the top of the transmission suspension bracket 81. The third support frame 13 and the fourth support frame 14 are respectively provided with a plurality of positioning holes corresponding to the mounting holes of the transmission suspension bracket 81 and the transmission suspension arm support 82. One end of each positioning detection pin 3 passes through the positioning hole and is inserted into the mounting hole of the transmission suspension bracket 81 and the mounting hole of the transmission suspension arm support 82.

[0040] In this embodiment, during testing, the third support frame 13 is used to support the bottom of the transmission suspension arm support 82. The third support frame 13 is provided with three positioning holes corresponding to the mounting holes of the transmission suspension arm support 82. Each of the three mounting holes is connected to a positioning inspection pin 3. When the mounting holes of the transmission suspension arm support 82 can be smoothly inserted into each positioning inspection pin 3, it can be determined that the mounting hole position of the transmission suspension arm support 82 is qualified.

[0041] Specifically, the top of the fourth support frame 14 is rotatably connected to a flip frame 141. The fourth support frame 14 and the flip frame 141 are fixed by fasteners. The flip frame 141 is provided with positioning holes corresponding to the wiring harness fixing holes of the transmission mount assembly 8. One end of the positioning pin 3 passes through each positioning hole and is inserted into the wiring harness fixing hole of the transmission mount assembly 8.

[0042] In this embodiment, the fourth support frame 14 is provided with a positioning pin 3 corresponding to the position of the top mounting hole of the transmission mount assembly 8.

[0043] In this embodiment, before the transmission mount assembly 8 is installed on the transmission mount assembly fixture, the flip frame 141 is flipped upwards to avoid interfering with the installation of the transmission mount assembly 8. After the clamping mechanism has completed the clamping and fixing of the transmission mount assembly 8, the flip frame 141 is flipped downwards. When the two positioning pins 3 on the flip frame 141 can be smoothly inserted into the wiring harness fixing hole of the transmission mount assembly 8, it can be determined that the position of the wiring harness fixing hole of the transmission mount assembly 8 is qualified.

[0044] Example 2:

[0045] This embodiment is similar to Embodiment 1, except that, in this embodiment, as shown... Figure 1-4 As shown, it also includes a go / no-go gauge 4 detachably connected to the base 1, the go / no-go gauge 4 being used to detect the mounting hole size of the transmission mount assembly 8.

[0046] In this embodiment, after the position detection of the mounting holes of the transmission mount assembly 8 is completed, the transmission mount assembly 8 is removed, and the dimensional accuracy of each mounting hole of the transmission mount assembly 8 can be checked one by one by the go / no-go gauge 4.

[0047] Specifically, the base 1 is provided with a first mounting seat 5, and the go / no-go gauge 4 is inserted into the first mounting seat 5.

[0048] In this embodiment, the first mounting base 5 can integrate the go / no-go gauge 4 onto the base 1, making it easy to access the go / no-go gauge 4. A plastic spring rope is also provided between the first mounting base 5 and the go / no-go gauge 4 to prevent the go / no-go gauge 4 from being lost.

[0049] Example 3:

[0050] This embodiment is similar to Embodiment 1, except that, in this embodiment, as shown... Figure 2 , 4 As shown in Figure 5, it also includes a handheld inspection block 6 that is detachably connected to the base 1. One side of the handheld inspection block 6 is provided with a hole diameter inspection pin 61 corresponding to the mounting hole position of the transmission suspension arm support 82.

[0051] In this embodiment, the handheld inspection block 6 can detect the diameter accuracy of the three mounting holes on the transmission suspension arm support 82. During the inspection, the transmission suspension arm support 82 is removed from the transmission suspension assembly fixture, and the diameter inspection pins 61 of the handheld inspection block 6 are aligned with the mounting holes on the transmission suspension arm support 82. When the diameter inspection pins 61 can be smoothly inserted into the mounting holes on the transmission suspension arm support 82, it can be determined that the diameter of the mounting holes on the transmission suspension arm support 82 is qualified.

[0052] Specifically, the base 1 is provided with a second mounting seat 7, and the handheld inspection block 6 is engaged with the second mounting seat 7.

[0053] In this embodiment, the second mounting base 7 can integrate the handheld inspection block 6 onto the base 1, making it convenient to access the handheld inspection block 6.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
