Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing technology, and specifically relates to an auxiliary fixture for processing automotive parts. Background Technology

[0002] The steering column, a key component of the automotive steering system, is an important steering column locking device, mainly composed of a locking lever, camshaft, locking stop, unlocking lever, and unlocking button. During normal vehicle use, when the driver removes the key from the ignition, the steering column is quickly locked by the locking lever. This locking mechanism effectively prevents vehicle theft. Even if a thief manages to start the engine without the key, the car cannot be steered due to the locked steering column, thus rendering it unusable. Therefore, the steering column is a crucial component of an automobile.

[0003] Currently, clamping tools are indispensable auxiliary equipment in the manufacturing process of steering columns. Their function is to accurately clamp and position the steering column to ensure machining accuracy and quality. However, existing steering column clamping tools have significant limitations. They typically only provide a single fixed positioning function. In actual machining, it is often necessary to adjust the lateral displacement or rotation of the positioned steering column according to different machining processes and requirements. However, existing clamping tools are not designed to fully consider these needs. To adjust the position of the steering column, operators often need to remove it from the clamping tool, readjust its position, and then clamp it again. This operation is not only cumbersome and time-consuming, severely reducing machining efficiency, but may also damage the steering column during repeated disassembly and reassembly, affecting product quality. Furthermore, frequent disassembly and reassembly operations increase the labor intensity and difficulty for operators, failing to meet the demands of modern, efficient, and precise machining production. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an auxiliary fixture for processing automotive parts, so as to solve the problem that the steering column is not easy to adjust flexibly after being clamped during the application of the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] An auxiliary fixture for processing automotive parts includes a mounting plate, a fixed seat fixedly mounted on the top center of the mounting plate, an adjustment component fixedly connected to the top center of the fixed seat, clamping components fixedly mounted on both sides of the top of the adjustment component, a steering column clamped on the inner side of the clamping component, and a drive mechanism fixedly connected to the top center of one side of the mounting plate.

[0007] The clamping assembly includes a support frame, which is fixedly connected to the top two sides of the adjustment assembly. A first electric push rod is fixedly connected to the top of the support frame. The output end of the first electric push rod passes through the support frame and is fixedly connected to a clamping frame. A clamping frame is also fixedly connected to the bottom of the support frame. The inner side of the clamping frame is provided with clamping grooves.

[0008] As a preferred technical solution, the side of the clamping groove is V-shaped, and the inside of the clamping groove is rotatably connected with balls at equal intervals.

[0009] As a preferred technical solution, the adjustment component includes a guide rail, which is fixedly connected to the top center of the fixed base. A lead screw is rotatably connected inside the guide rail. A first motor is fixedly connected to one end of the guide rail. The output end of the first motor passes through the guide rail and is fixedly connected to the lead screw. The lead screw is rotatably connected inside the guide rail. The two ends of the lead screw have opposite thread directions. Both ends of the lead screw are threadedly connected to sliders. The top of the sliders is fixedly connected to the bottom of the support frame.

[0010] As a preferred technical solution, mounting holes are provided at all four corners of the mounting plate, the mounting holes are countersunk holes, and all edges of the mounting plate are rounded.

[0011] As a preferred technical solution, the internal cavity of the guide rail is convex in cross-sectional shape, the side of the slider is also convex in shape, and a wear-resistant pad is fixedly connected to the outer surface of the slider.

[0012] As a preferred technical solution, the driving mechanism includes a fixed plate, which is fixedly installed on the middle of the rear side of the top of the mounting plate. A second electric push rod is fixedly connected to the middle of the back side of the fixed plate. The output end of the second electric push rod passes through the fixed plate and is fixedly connected to a connecting rod. A circular plate is fixedly connected to the top of the connecting rod. A second motor is fixedly connected to the back side of the circular plate. The output end of the second motor passes through the circular plate and is fixedly connected to a concave seat. A third motor is fixedly connected to one side of the concave seat. The output end of the third motor passes through the concave seat and is fixedly connected to a drive wheel. The drive wheel is rotatably connected to the inside of the concave seat.

[0013] As a preferred technical solution, the outer surface of the drive wheel is fixedly connected with anti-slip protrusions at equal intervals, and the first motor, the second motor and the third motor are all configured as brake motors.

[0014] In summary, the present invention has the following main advantages:

[0015] First, this device uses an adjustment component and a drive mechanism to improve the convenience of positioning during processing. During use, regarding the adjustment component, after starting the first motor, the lead screw rotates and drives the slider to slide along the guide rail. By using the reverse screw threads at both ends, the two sliders move synchronously in opposite directions, realizing the lateral displacement adjustment of the clamping component. This allows for flexible adaptation to steering columns of different lengths. Combined with the V-shaped clamping groove and the first electric push rod, it can firmly clamp and accurately center the steering column, improving the stability and convenience of use.

[0016] Secondly, by setting up a drive mechanism, after the device completes clamping, the second electric push rod can be used to make the drive wheel fit against the steering column, and the brake motor provides reliable locking. When adjusting the position, the third motor can be started to drive the steering column to move laterally. If rotation adjustment is required, the second electric push rod can be used in conjunction with the second motor to change the direction of the drive wheel, and then the third motor can be driven to achieve this. The two work together to meet diverse processing needs and ensure stable and convenient operation of the device. Attached Figure Description

[0023] Example

[0024] refer to Figures 1 to 5An auxiliary fixture for processing automotive parts according to this embodiment includes a mounting plate 1, a fixed base 2 fixedly mounted on the top center of the mounting plate 1, an adjustment component 3 fixedly connected to the top center of the fixed base 2, clamping components 4 fixedly mounted on both sides of the top of the adjustment component 3, a steering column 5 clamped on the inner side of the clamping component 4, and a drive mechanism 6 fixedly connected to the top center of one side of the mounting plate 1.

[0025] The clamping assembly 4 includes a support frame 41, which is fixedly connected to the top two sides of the adjusting assembly 3. A first electric push rod 42 is fixedly connected to the top of the support frame 41. The output end of the first electric push rod 42 passes through the support frame 41 and is fixedly connected to a clamping frame 43. A clamping frame 43 is also fixedly connected to the bottom of the support frame 41. The inner side of the clamping frame 43 is provided with clamping grooves 44. When this automotive parts processing auxiliary fixture is working, the steering column 5 can be placed in the clamping assembly 4 first. The adjusting assembly 3 is installed on the top of the fixed base 2, and the position of the clamping assembly 4 can be adjusted to adapt to steering columns 5 of different specifications. To meet installation requirements, after the steering column 5 is placed between the two clamping frames 43 of the clamping assembly 4, the first electric push rod 42 is activated. The output end of the first electric push rod 42 pushes the top clamping frame 43 downward to move down and cooperate with the clamping frame 43 at the bottom of the support frame 41. The clamping groove 44 is used to clamp and fix the steering column 5. The drive mechanism 6 on the top side of the mounting plate 1 can drive the steering column 5 according to processing needs after it is clamped, such as driving the steering column 5 to rotate or move, to assist in completing subsequent processing steps, thereby achieving stable clamping and precise processing assistance for the steering column 5.

[0026] refer to Figure 4 The side of the clamping groove 44 is V-shaped, and the inside of the clamping groove 44 is rotatably connected with balls 45 at equal intervals. The V-shaped side of the clamping groove 44, with its unique inclined structure, can automatically guide the steering column 5, making it quickly and accurately centered and achieving stable clamping. At the same time, the rotatably connected balls 45 at equal intervals inside the clamping groove 44 can effectively reduce the frictional resistance between the steering column 5 and the clamping groove 44. When the steering column 5 needs to be adjusted in position or processed, under the action of the drive mechanism 6, the steering column 5 can move or rotate more smoothly in the clamping groove 44, which not only ensures the stability of clamping, but also reduces the wear on the surface of the steering column 5, and provides good conditions for the drive mechanism 6 to drive the steering column 5, ensuring that the processing is carried out efficiently and stably.

[0027] refer to Figures 1-3The adjustment component 3 includes a guide rail 31, which is fixedly connected to the top center of the fixed base 2. A lead screw 32 is rotatably connected inside the guide rail 31. A first motor 33 is fixedly connected to one end of the guide rail 31. The output end of the first motor 33 passes through the guide rail 31 and is fixedly connected to the lead screw 32. The lead screw 32 is rotatably connected inside the guide rail 31. The two ends of the lead screw 32 have opposite thread directions. Both ends of the lead screw 32 are threadedly connected to sliders 34. The top of the sliders 34 is fixedly connected to the bottom of the support frame 41. Mounting holes 7 are provided at the four corners of the mounting plate 1. The mounting holes 7 are countersunk holes. All edges of the mounting plate 1 are rounded. The cross-sectional shape of the internal cavity of the guide rail 31 is convex. The side shape of the slider 34 is also convex. Wear-resistant pads are fixedly connected to the outer surface of the slider 34. When the adjustment component 3 of this auxiliary fixture is working, the first motor 33 is fixed to one end of the guide rail 31. After starting, its output end drives the lead screw 32 to move along the guide rail 31. 1. Internal rotation: Since the threads at both ends of the lead screw 32 rotate in opposite directions and are threadedly connected to the sliders 34 at both ends, when the lead screw 32 rotates, the two sliders 34 can slide synchronously in opposite directions within the guide rail 31. Furthermore, since the top of the slider 34 is fixedly connected to the bottom of the support frame 41 of the clamping assembly 4, the sliding of the slider 34 can drive the clamping assembly 4 to perform lateral displacement adjustment, thereby flexibly changing the distance between the two clamping assemblies 4 to accommodate steering columns 5 of different lengths. The internal cavity of the guide rail 31 and the slider 34 are both convex, and their mutual cooperation can effectively limit the movement direction of the slider 34, preventing it from dislodging from the guide rail 31 and ensuring the stability of the movement. The wear-resistant pads on the outer surface of the slider 34 can reduce frictional wear between the slider 34 and the guide rail 31, extending its service life. In addition, countersunk holes are provided at the four corners of the mounting plate 1 for easy installation and fixation, and the rounded design at each corner can prevent scratching operators or workpieces, reflecting the safety and practicality of the design.

[0028] refer to Figures 1-3 and Figure 5The drive mechanism 6 includes a fixed plate 61, which is fixedly installed on the middle of the rear top of the mounting plate 1. A second electric push rod 62 is fixedly connected to the middle of the back side of the fixed plate 61. The output end of the second electric push rod 62 passes through the fixed plate 61 and is fixedly connected to a connecting rod 63. A circular plate 64 is fixedly connected to the top of the connecting rod 63. A second motor 65 is fixedly connected to the back of the circular plate 64. The output end of the second motor 65 passes through the circular plate 64 and is fixedly connected to a concave seat 66. A third motor 67 is fixedly connected to one side of the concave seat 66. The output end of the third motor 67 passes through the concave seat 66 and is fixedly connected to a drive wheel 68. The drive wheel 68 is rotatably connected to the inside of the concave seat 66. Anti-slip protrusions are fixedly connected at equal intervals on the outer surface of the drive wheel 68. The first motor 33, the second motor 65, and the third motor 67 are all brake motors. When the drive mechanism 6 is working, the second electric push rod 62 is fixed to the back of the fixed plate 61. After starting, its output end pushes the connecting rod 63 to drive the circular plate 64, the second motor 65, and the concave seat 66. The seat 66, the third motor 67, and the drive wheel 68 move forward, causing the drive wheel 68 to fit against the outer surface of the steering column 5. Since the first motor 33, the second motor 65, and the third motor 67 are all brake motors, they can provide reliable locking when not in operation. Combined with the tight contact between the anti-slip protrusion of the drive wheel 68 and the steering column 5, stable clamping and positioning are achieved. When it is necessary to adjust the lateral displacement of the steering column 5, the third motor 67 is started, and its output end drives the drive wheel 68 to rotate. By means of the friction between the anti-slip protrusion and the steering column 5, the steering column 5 is driven to move laterally within the clamping assembly 4. If it is necessary to adjust the rotation angle of the steering column 5, the second electric push rod 62 is first started to fine-tune the position of the drive wheel 68, and then the second motor 65 is started, and its output end drives the concave seat 66 to rotate, changing the rotation direction of the drive wheel 68. Then, the second electric push rod 62 is used again to make the drive wheel 68 and the steering column 5 close contact again. Finally, the third motor 67 is started to drive the steering column 5 to rotate, thereby realizing diversified movement adjustment of the steering column 5.

[0029] Operating principle and advantages: This device, by setting the adjustment component 3, enables the first motor 33 to drive the lead screw 32 to rotate when the first motor 33 is started during use. Under the threaded transmission cooperation between the lead screw 32 and the slider 34, the slider 34 can slide stably along the inside of the guide rail 31. Since the two ends of the lead screw 32 adopt the opposite thread direction design, the two sliders 34 can move synchronously and in opposite directions, thereby driving the clamping component 4 installed on the top of the slider 34 to adjust the lateral displacement. In this way, the distance between the two clamping components 4 can be flexibly adjusted to adapt to the steering column 5 of different length specifications.

[0030] In actual operation, the steering column 5 is placed in the clamping groove 44 with a V-shaped side structure, and then the first electric push rod 42 is activated. The first electric push rod 42 pushes the top clamping frame 43 downward through precise linear drive, so as to reliably clamp and fix the steering column 5. The design of the V-shaped clamping groove 44 not only provides a stable clamping and positioning effect, but its internal inclined structure can also guide the steering column 5, so as to make the steering column 5 quickly and accurately center, effectively improving the stability and ease of operation of the device.

[0031] By setting up a drive mechanism 6, this device can have complete motion control and adjustment capabilities. After the clamping adjustment of the steering column 5 is completed, the second electric push rod 62 is activated, which can make the drive wheel 68 at the top of the connecting rod 63 fit tightly against the outer surface of the steering column 5. Thanks to the design of the first motor 33, the second motor 65 and the third motor 67 as brake motors, a reliable locking function can be provided when the motor is not running. Combined with the squeezing action of the drive wheel 68 on the steering column 5, a stable clamping and positioning effect is achieved.

[0032] When the position of the steering column 5 needs to be adjusted, if lateral displacement is required, the third motor 67 can be started to drive the drive wheel 68 to rotate. The anti-slip protrusion 69 on the outer surface of the drive wheel 68 can enhance the friction between it and the steering column 5, ensuring effective power transmission, thereby driving the steering column 5 to move laterally within the clamping groove 44. If the steering column 5 needs to be rotated, the contact state between the drive wheel 68 and the steering column 5 is first adjusted by the second electric push rod 62. Then, the second motor 65 is started to drive the concave seat 66 to rotate, changing the rotation direction of the drive wheel 68. Then, the second electric push rod 62 is used to make the drive wheel 68 re-contact the outer surface of the steering column 5. Finally, the third motor 67 is started to drive the drive wheel 68 to rotate, realizing the rotational movement of the steering column 5.

[0033] By adjusting the coordinated operation of component 3 and drive mechanism 6, this device can achieve stable clamping and flexible adjustment of steering column 5, effectively meeting the diverse position adjustment needs during the processing of steering column 5, and significantly improving the stability and ease of operation of the device.
