Description

Technical Field

[0001] This application relates to the field of automotive parts testing equipment technology, and in particular to a simple connecting rod testing fixture. Background Technology

[0002] The connecting rod is typically connected to the parking pawl and transmission in the parking mechanism to transmit the output torque of the parking mechanism to the transmission, thereby changing the rotation and torque of the car engine. Therefore, the connecting rod is an important component in the car parking mechanism. If the connecting rod is too long or too short, it will not be able to fit tightly with the parking pawl and transmission, causing the car to jam when parked, making it unable to perform parking operations effectively. Therefore, the length of the connecting rod needs to be measured before assembling it with the transmission and parking pawl.

[0003] Because the connecting rod is irregularly shaped, a coordinate measuring machine (CMM) is required to measure it. However, CMMs are bulky, difficult to move, and not convenient for use in small spaces such as laboratories or sampling stations. Utility Model Content

[0026] refer to Figures 1 to 6 A simplified connecting rod inspection fixture according to a preferred embodiment of this application will be described in detail below. The simplified connecting rod inspection fixture is used to inspect the connecting rod 90 connecting the gearbox and the parking pawl.

[0027] Specifically, the two ends of the connecting rod 90 are defined as a head 91 and a tail 92, respectively, wherein the end of the tail 92 away from the head 91 is bent to form an extension 921. The extension 921 has two shaped protrusions 9211 formed on its own sidewall, and the two shaped protrusions 9211 are located at different positions in the axial direction of the extension 921 and are spaced apart by a predetermined distance.

[0028] The simplified connecting rod testing fixture includes a loading mechanism 10 and a measuring mechanism 20, wherein the loading mechanism 10 includes a first loading component 11. The first loading component 11 forms a receiving groove 1101 adapted to the shape and size of at least a portion of the connecting rod 90. The measuring mechanism 20 includes a length detection component 21. The length detection component 21 is mounted on the first loading component 11, and the length detection component 21 is opposite to the end face of the head 91 away from the tail 92, and the length detection component 21 is used to detect the length of the connecting rod 90.

[0029] The simplified connecting rod testing fixture also includes a fixing mechanism 30, which includes a first fixing member 31, and the first fixing member 31 includes a plurality of first positioning pins 311. The first loading member 11 forms a plurality of first insertion holes 1102 penetrating the two opposite sidewalls of the receiving groove 1101, and the plurality of first insertion holes 1102 are spaced apart along the length direction of the receiving groove 1101. Each first positioning pin 311 is detachably inserted into a first insertion hole 1102, and at least one first positioning pin 311 is positioned above the connecting rod 90 and at least one first positioning pin 311 is positioned below the connecting rod 90. The first positioning pins 311 inserted into the first insertion holes 1102 abut against the connecting rod 90, so that the plurality of first positioning pins 311 and the inner wall of the receiving groove 1101 work together to maintain the posture and position of the connecting rod 90, thereby fixing the connecting rod 90. After the connecting rod 90 is fixed to the receiving groove 1101 by the first fixing member 31 in a preset posture, the length detection member 21 measures the length of the connecting rod 90.

[0030] Preferably, the first fixing member 31 further includes a stop member 312. One end of the stop member 312 forms a limiting groove 31201. The first loading member 11 also forms a first insertion channel 1103 penetrating the two opposite sidewalls of the receiving groove 1101, and the end of the stop member 312 forming the limiting groove 31201 is detachably inserted into the first insertion channel 1103. When the connecting rod 90 is placed in the receiving groove 1101 with the extension 921 facing vertically and the head 91 close to the length detection member 21, multiple first positioning pins 311 are sequentially inserted into the corresponding first insertion holes 1102, and the end of the stop member 312 forming the limiting groove 31201 is inserted into the first insertion channel 1103, and the limiting groove 31201 moves radially towards the extension 921 so that the extension 921 is engaged in the limiting groove 31201. In this way, the anti-movement member 312 and the first loading member 11 work together to restrict the connecting rod 90 from moving along its own length direction; the first positioning pin 311 restricts the connecting rod 90 from moving vertically; the two opposite sidewalls of the receiving groove 1101 restrict the connecting rod 90 from moving horizontally in a direction perpendicular to its own length direction. Thus, the first loading member 11 and the first fixing member 31 fix the connecting rod 90 from multiple directions to improve the accuracy of the length detection result of the length detection member 21.

[0031] In one embodiment, the length detection component 21 is implemented as a length sensor.

[0032] As a deformable feature, the first loading member 11 forms a notch 1104 communicating with the receiving groove 1101 along its length. The receiving groove 1101 formed by the first loading member 11 is adapted to the shape and size of a portion of the connecting rod 90, the connecting rod 90 being placed in the receiving groove 1101 with its head 91 extending from the notch 1104. The length detection member 21 has an abutting end 211 facing the notch 1104. The end face of the head 91 away from the tail 92 abuts against the abutting end 211, and the length detection member 21 is configured to measure the length of the connecting rod 90 by being pressed against the abutting end 211 by the connecting rod 90. As an example, the length detection member 21 is implemented as a dial indicator or a micrometer indicator.

[0033] It is worth mentioning that the first loading component 11 has a mounting groove 1105 that communicates with the receiving groove 1101 at one end near the notch 1104. The calibration block is detachably mounted in the mounting groove 1105, and the calibration block abuts against the abutting end 211 through the notch 1104 to calibrate the length detection component 21.

[0034] Preferably, the length detection component 21 is detachably mounted on the first loading component 11.

[0035] Specifically, the first loading component 11 includes a loading member 111 and a mounting member 112. The loading member 111 forms the receiving groove 1101, the first insertion hole 1102, the first insertion channel 1103, the notch 1104, and the mounting groove 1105. The mounting member 112 is mounted on one end of the loading member 111 where the notch 1104 is formed. The mounting member 112 forms a through hole 11201 and an adjustment groove 11202 communicating with the through hole 11201, and a portion of the mounting member 112 is divided into two assembly parts 1121 by the adjustment groove 11202. The abutting end 211 of the length detection component 21 passes through the through hole 11201. Fasteners are installed on the two assembly parts 1121. When the fasteners are tightened, they drive the two assembly parts 1121 to move closer to each other so that the assembly parts 1121 hug the abutting end 211, thereby fixing the length detection component 21. The inspection personnel can disassemble and assemble the length detection component 21 by disassembling and assembling the fasteners.

[0036] Furthermore, the loading mechanism 10 also includes a second supporting component 12. The first loading component 11 further includes a connecting member 113, to which the loading component 111 is mounted. The second supporting component 12 includes a fixed portion 121 and a movable portion 122, wherein the fixed portion 121 is fixedly mounted to the connecting member 113, and the movable portion 122 is movably connected to the fixed portion 121, and the movable portion 122 moves to move closer to or away from the fixed portion 121. The fixed portion 121 and the movable portion 122 together form a detection groove 1201, and the tail portion 92 of the connecting rod 90 is detachably inserted into the detection groove 1201 with the extension portion 921 facing vertically. The movable part 122 moves away from the fixed part 121 to open the detection slot 1201 so that the tail 92 of the connecting rod 90 can be inserted into or removed from the detection slot 1201; the movable part 122 moves towards the fixed part 121 to close the detection slot 1201.

[0037] The measuring mechanism 20 further includes a size detection component 22, which includes a stop gauge 221 and a go gauge 222. The stop gauge 221 forms a first slot 22101, and the go gauge 222 forms a second slot 22201 of the same size as the first slot 22101. The thickness of the end of the stop gauge 221 forming the first slot 22101 is greater than the preset distance between the two shaped protrusions 9211, and the thickness of the end of the go gauge 222 forming the second slot 22201 is less than the preset distance between the two shaped protrusions 9211. The fixed part 121 or the movable part 122 forms a second insertion channel 1202 communicating with the detection slot 1201. Both the stop gauge 221 and the go gauge 222 are detachably inserted into the second insertion channel 1202, and the second insertion channel 1202 corresponds to the extension 921 between the two shaped protrusions 9211.

[0038] Specifically, when the distance between the two molded protrusions 9211 is within a preset range, the end of the stop gauge 221 forming the first slot 22101 approaches the extension 921 radially through the second insertion channel 1202. Since the thickness of the end of the stop gauge 221 forming the first slot 22101 is greater than the preset distance between the two molded protrusions 9211, the extension 921 cannot be inserted into the first slot 22101. The end of the go gauge 222 forming the second slot 22201 approaches the extension 921 radially through the second insertion channel 1202. Since the thickness of the end of the go gauge 222 forming the second slot 22201 is less than the preset distance between the two molded protrusions 9211, the extension 921 portion between the two molded protrusions 9211 can be engaged in the second slot 22201. When the distance between the two molded protrusions 9211 of the connecting rod 90 exceeds a preset range, the extension portion 921 located between the two molded protrusions 9211 can be engaged in the second slot 22201 and the first slot 22101. When the distance between the two molded protrusions 9211 of the connecting rod 90 is less than the preset range, the extension portion 921 located between the two molded protrusions 9211 cannot be engaged in the second slot 22201 and the first slot 22101.

[0039] It is understood that when the distance between the two molded protrusions 9211 is within a preset range, the dimensions of the two molded protrusions 9211 along the axial direction of the extension 921 are within a preset size. When the distance between the two molded protrusions 9211 exceeds the preset range, the dimension of one or both molded protrusions 9211 along the axial direction of the extension 921 is smaller than the preset size. When the distance between the two molded protrusions 9211 is less than the preset range, the dimension of one or both molded protrusions 9211 along the axial direction of the extension 921 is larger than the preset size.

[0040] In one embodiment, the stop gauge 221 and the go gauge 222 are two separate elements.

[0041] As deformable, the stop gauge 221 and the go gauge 222 are integrally formed, with the end of the stop gauge 221 away from the first slot 22101 connected to the end of the go gauge 222 away from the second slot 22201.

[0042] Both the stop gauge 221 and the go gauge 222 form identification marks 223. The straight-line distance between the identification mark 223 formed by the stop gauge 221 and the opening of the first slot 22101 formed by the stop gauge 221 is the same as the straight-line distance between the identification mark 223 formed by the go gauge 222 and the opening of the second slot 22201 formed by the go gauge 222. During inspection, the inspector determines whether the distance between the two molded protrusions 9211 is within a preset range by observing the final positions of the identification marks 223 formed on the stop gauge 221 and the go gauge 222.

[0043] As an example, the identification mark 223 is implemented as a groove.

[0044] Preferably, the fixing mechanism 30 further includes a plurality of second positioning pins 32. The second bearing member 12 forms a plurality of second insertion holes 1203 penetrating the two opposite sidewalls of the detection groove 1201. Each second positioning pin 32 is detachably inserted into a second insertion hole 1203, and at least one second insertion hole 1203 is positioned above the tail 92 and at least one second positioning pin 32 is positioned below the tail 92. The second positioning pins 32 inserted into the second insertion holes 1203 are kept in contact with the tail 92. In this way, the plurality of second positioning pins 32 and the inner wall of the detection groove 1201 work together to maintain the posture and position of the connecting rod 90, thereby fixing the connecting rod 90. After the connecting rod 90 is fixed in the detection groove 1201 in a preset posture by the second positioning pins 32, the size detection member 22 detects the distance between the two shaped protrusions 9211.

[0045] Preferably, the mounting member 113 forms a plurality of placement holes 11301, and the first positioning pin 311 and the second positioning pin 32 are detachably inserted into the placement holes 11301 to accommodate the first positioning pin 311 and the second positioning pin 32.
