Description

Technical Field

[0001] This utility model relates to the technical field of automotive steering knuckle processing equipment, and more specifically to an automotive steering knuckle marking fixture. Background Technology

[0002] Many existing automotive steering knuckles are quite similar, such as the first and second automotive steering knuckles. They are also divided into left and right corresponding steering knuckles. Steering knuckles in the same direction are the first steering knuckle on the left and the second steering knuckle on the left. The structure and position of the connecting arm formed on the left and upper right sides are quite similar, and the through holes at their corresponding ends are also quite similar. However, the inner diameter of one through hole is larger than the inner diameter of the other. Therefore, when marking two automotive steering knuckles, they use the same set of tooling.

[0003] However, during production, because the structures of the two car steering knuckles are too similar, operators are prone to misreading them, which may result in the number used for one car steering knuckle being printed on the other, causing incorrect coding and affecting subsequent processing or packaging. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a coding fixture for automotive steering knuckles. It can sense two automotive steering knuckles to determine which type of automotive steering knuckle it is, ensuring accurate coding and correct subsequent processing and packaging.

[0005] The solution of this utility model to the aforementioned technical problem is:

[0006] A marking fixture for automotive steering knuckles includes a fixed base plate, a horizontal fixing plate fixed to the right side of the top surface of the fixed base plate, a vertical support column fixed to the top right side of the top surface of the horizontal fixing plate, an upper connecting block fixed to the top of the vertical support column, and an end positioning block fixed to the middle of the top surface of the upper connecting block.

[0007] A left fixing block is fixed to the top left side of the horizontal fixing plate, and a positioning sleeve is fixed to the top surface of the left fixing block. A telescopic through hole is formed in the middle of the top plate of the positioning sleeve. The positioning pin is inserted into the telescopic through hole, and the upper part of the positioning pin extends out of the top of the telescopic through hole. A spring is inserted into the positioning sleeve. The bottom surface of the left connecting part of the automobile steering knuckle to be processed is above the top surface of the positioning sleeve, and the upper part of the positioning pin extends out of the top of the middle through hole of the left connecting part.

[0008] A support is fixed to the left side of the top surface of the fixed base plate, and a sensor is fixed to the upper part of the support. The sensing end of the sensor faces the upper side wall of the positioning column.

[0009] A controller is fixed to the left side of the top surface of the fixed base plate, and the sensor is electrically connected to the controller via an electrical connection wire.

[0010] A central support plate is fixed to the rear part of the middle part of the top surface of the horizontal fixed plate. The front wall of the central support plate is an oblique wall extending obliquely backward and upward. The lower part of the automobile steering knuckle to be processed has a rear extension extending backward. The rear wall of the rear extension presses against the front wall of the central support plate.

[0019] For example, see below. Figures 1 to 6 As shown, a coding fixture for automotive steering knuckles includes a fixed base plate 10. A horizontal fixing plate 11 is fixed to the right side of the top surface of the fixed base plate 10. A vertical support column 12 is fixed to the top right side of the top surface of the horizontal fixing plate 11. An upper connecting block 13 is fixed to the top of the vertical support column 12. An end positioning block 20 is fixed to the middle of the top surface of the upper connecting block 13.

[0020] A left fixing block 14 is fixed to the top left side of the horizontal fixing plate 11. A positioning sleeve 30 is fixed to the top surface of the left fixing block 14. A telescopic through hole is formed in the middle of the top plate of the positioning sleeve 30. A positioning post 31 is inserted into the telescopic through hole. The upper part of the positioning post 31 extends out of the top of the telescopic through hole. A spring 32 is inserted into the positioning sleeve 30. A radially extending edge 311 is formed on the lower outer wall of the positioning post 31. The radially extending edge 311 is in the positioning sleeve 30. Its top surface presses against the bottom edge of the top plate of the positioning sleeve 30. The bottom end of the spring 32 is applied to the top surface of the left fixing block 14. The top end of the spring 32 is applied to the bottom surface of the radially extending edge 311. The bottom of the positioning post 31 is inserted into the top of the spring 32.

[0021] The bottom surface of the left connecting part 101 of the automotive steering knuckle 100 to be processed is above the top surface of the positioning sleeve 30, and the upper part of the positioning pin 31 extends out of the top of the middle through hole of the left connecting part 101.

[0022] A support member 40 is fixed to the left side of the top surface of the fixed base plate 10, and a sensor 50 is fixed to the upper part of the support member 40. The sensing end of the sensor 50 faces the upper side wall of the positioning column 31.

[0023] Furthermore, the top surface of the fixed base plate 10 is fixed with gripping parts 1 on both the left and right sides. The gripping parts 1 facilitate lifting and moving the entire tooling.

[0024] Furthermore, a controller 2 is fixed on the left side of the top surface of the fixed base plate 10. The sensor 50 is electrically connected to the controller 2 via an electrical connection line. The controller 2 is electrically connected to the coding equipment via an electrical connection line. It can receive and process the sensing signal and transmit this signal to the control host electrically connected to it. The control host can control the corresponding coding equipment to perform the corresponding coding processing operation. It is a conventional structure and will not be described in detail here.

[0025] The support member 40 is a bent member, including a vertical part, the bottom end of which is formed with a horizontal bent part, which is fixed to the top surface of the fixed base plate 10. A sensor 50 is fixed to the upper part of the vertical part. The sensor 50 used in this embodiment is an infrared lidar ranging sensor, which can detect distances from 0 to 1 meter.

[0026] A central support plate 60 is fixed to the rear part of the middle part of the top surface of the horizontal fixed plate 11. The front wall of the central support plate 60 is an oblique wall extending obliquely backward and upward. The lower part of the automobile steering knuckle 100 to be processed has a rear extension 102 extending backward. The rear wall of the rear extension 102 presses against the front wall of the central support plate 60.

[0027] The top surface of the upper connecting block 13 is an inclined wall surface, with its left end higher than its right end. The bottom surface of the end positioning block 20 presses against the top surface of the upper connecting block 13 and is fixedly connected by bolts.

[0028] The top surface of the end positioning block 20 has an upwardly extending column part 21 formed in the middle. The outer side wall of the top end of the column part 21 is a conical wall with a large bottom outer diameter and a small top outer diameter. The upper right side of the connecting arm 103 formed on the automobile steering knuckle 100 has a positioning through hole formed in the middle of its end. The bottom surface of the end of the connecting arm 103 presses against the top edge of the end positioning block 20. The column part 21 is inserted into the positioning through hole of the connecting arm 103, and its outer side wall is close to the inner side wall of the positioning through hole.

[0029] like Figure 2 As shown, in this embodiment, when in use, the left first steering knuckle is installed, and the rear wall of its extension 102 presses against the front wall of the middle support plate 60. The column part 21 is inserted into the positioning through hole of the corresponding connecting arm 103, while the top of the positioning pin 31 is inserted into the middle through hole of the left connecting part 101. Since the positioning pin 31 cannot be fully inserted into the middle through hole of the left connecting part 101, only the side wall of its top conical wall presses against the lower inner side wall of the middle through hole, so that the upper part of the positioning pin 31 cannot extend out of the top of the middle through hole of the left connecting part 101, so that its bottom is in the positioning sleeve 30, the spring 32 is compressed, and at this time, the infrared rays of the sensor 50 directly irradiate the left first steering knuckle. On the corresponding wall surface, the detected distance is greater than the distance when the infrared rays of sensor 50 directly illuminate the upper side wall of positioning post 31 without the left first steering knuckle being placed. The sensing signal is transmitted to controller 2, controller 2 obtains the distance value and transmits it to the control host. The control software of the control host compares this data with the distance of the sensing positioning post 31 when the left first steering knuckle is not installed. If the deviation is large, it indicates that the upper part of positioning post 31 has not extended, indicating that the left first steering knuckle is being clamped at this time. Then, the electrically connected coding device can be controlled to code the corresponding number. Since this embodiment is only used for coding the steering knuckle, the clamping accuracy requirement is not high, and only positioning is required.

[0030] like Figure 3 As shown, the second steering knuckle on the left is installed at this time. The upper part of the positioning post 31 extends out of the middle through hole of the corresponding left connecting part 101. At this time, the infrared rays of the sensor 50 directly irradiate the upper part of the positioning post 31. The detected distance is compared with the distance of the sensing positioning post 31 when the first steering knuckle on the left is not installed. The values ​​are similar, indicating that the second steering knuckle on the left is installed. Then the coding device connected to the electrical control can be used to code the corresponding number.

[0031] This embodiment ensures that the first and second steering knuckles on the left side will not be incorrectly coded, guaranteeing accurate coding.

[0032] like Figure 4 As shown, it is the structure for clamping the first and second vehicle steering knuckles on the right side, which is exactly opposite to the clamping structure of this embodiment.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
