Description

Technical Field

[0001] The utility model relates to the technical field of knuckle processing, and particularly relates to a turnover fixture for front knuckle processing. Background Technique

[0002] The knuckle is one of the core parts on the automotive steering axle, which can enable the vehicle to drive stably and transmit the driving direction sensitively. The function of the knuckle is to bear the vehicle dynamic load, support and drive the moving wheel to rotate around the kingpin to make the vehicle turn. Under the driving state of the vehicle, it bears variable impact loads.

[0003] The utility model patent application document with the publication number of "CN211332301 U" discloses a turnover type knuckle fixing device, which mainly consists of a base, a disc, a cylinder, a pressing device and a positioning block. The knuckle rod part of this technical solution passes through the positioning block and fits with the side surface of the disc part to realize the positioning of the knuckle. The knuckle is fixed by the cylinder and the pressing device, and then the base drives the knuckle to turn a certain angle. The drill bit drills the disc part through the guide hole, which is convenient to use, reduces the labor intensity of workers and improves work efficiency.

[0004] The turnover type knuckle fixing device disclosed in the above document has the following defects: the position of the pressing device cannot be adjusted during the use of this device, so that the pressing device can only press part of the knuckles. When the size of the knuckle is smaller than the pressing device, the pressing device cannot achieve a good fixing effect.

[0005] It can be seen from this that the existing turnover type knuckle fixing device cannot adjust the position of the pressing structure, and it is necessary to improve the existing deficiencies and provide a turnover fixture for front knuckle processing. Content of the Utility Model

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the attached drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1 - Figure 4 As shown, the present utility model is a flipping fixture for machining a front steering knuckle, including a base 1. Two chutes are provided on the upper surface of the base 1. A moving component 2 is provided inside each of the two chutes. A pressing component 3 is provided on the upper surface of the moving component 2. A bottom plate 4 is provided at the lower end of the base 1. Two support plates 401 are provided on the upper surface of the bottom plate 4. One end of each of the two support plates 401 is rotatably connected to a rotating shaft 5. A driving motor 6 is provided outside one of the support plates 401. The output end of the driving motor 6 is installed with the rotating shaft 5. Discs 501 are provided at the other ends of the two rotating shafts 5. The base 1 is installed between the two discs 501;

[0027] When machining the front steering knuckle, by starting the driving motor 6, the output end of the driving motor 6 drives the rotating shaft 5 to rotate, so that the rotating shaft 5 rotates axially around the installation hole provided in the support plate 401, and the rotating shaft 5 drives the base 1, the moving component 2, the pressing component 3 and the front steering knuckle to rotate through the disc 501, realizing the flipping of the front steering knuckle;

[0028] The pressing component 3 includes a cylinder 301. A connecting plate 302 is provided at the output end of the cylinder 301. A connecting rod 303 is provided on the lower surface of the connecting plate 302. A butting block 304 is provided on the lower surface of the connecting rod 303. The cylinder 301 is installed inside the connecting seat 203;

[0029] By placing the front steering knuckle on the base 1 and starting the cylinder 301, the output end of the cylinder 301 moves downward for reset. When the output end of the cylinder 301 moves, it drives the connecting plate 302, the connecting rod 303, and the butting block 304 to move downward, so that the butting block 304 presses and fixes the front steering knuckle;

[0030] One end of the connecting plate 302 is provided with a chuck 305. The chuck 305 is sleeved on the outer surface of the output end of the cylinder 301. Threaded holes are provided on the outer surface of the chuck 305. A hand-tightening bolt 306 is threadedly connected inside the threaded holes;

[0031] When the pressing position of the butting block 304 needs to be adjusted, by rotating the hand-tightening bolt 306, the hand-tightening bolt 306 gradually disengages from the inside of the threaded hole, thereby making the chuck 305 loose. Then, by rotating the connecting plate 302, the chuck 305 rotates axially around the output end of the cylinder 301, so that the positions of the connecting plate 302, the connecting rod 303, and the butting block 304 are changed. After adjustment, rotate the hand-tightening bolt 306 in the reverse direction to make the chuck 305 tight, and the fixation of the position of the connecting plate 302 can be completed;

[0032] Anti-slip grooves are provided on the lower surface of the butting block 304;

[0033] Through the anti-slip grooves provided on the lower surface of the butting block 304, the friction between the butting block 304 and the front steering knuckle can be increased, avoiding the movement of the position of the front steering knuckle during use;

[0034] The moving component 2 includes a slide rail 201. Two first sliders 202 are slidably connected to the upper surface of the slide rail 201. Connecting seats 203 are provided on the upper surfaces of the two first sliders 202. A second slider 204 is installed on the lower surface of the slide rail 201. A one-way screw 205 is rotatably connected inside the chute. The second slider 204 is slidably connected to the outer surface of the one-way screw 205. One end of the one-way screw 205 penetrates through the base 1 and is provided with a rotating handle 206;

[0035] When the position of the pressing assembly 3 cannot press the front steering knuckle with a larger or smaller size, by rotating the rotating handle 206, the rotating handle 206 drives the one-way screw 205 to rotate, so that the one-way screw 205 rotates axially around the mounting hole of the base 1. During the rotation of the one-way screw 205, the second slider 204 moves along the axis in the chute, and then the slide rail 201 moves on the base 1, so as to achieve the effect of adjusting the lateral position of the pressing assembly 3. When the two slide rails 201 are located at both ends of the front steering knuckle, stop rotating the rotating handle 206. By pushing the first slider 202, the first slider 202 slides on the slide rail 201, so that the pressing assembly 3 moves longitudinally, and then the effect of adjusting the longitudinal position of the pressing assembly 3 is achieved, which is convenient for the pressing assembly 3 to press and fix the front steering knuckle with different sizes;

[0036] Both ends of the slide rail 201 are provided with stoppers 207;

[0037] When the first slider 202 moves on the slide rail 201, the position of the first slider 202 can be limited by the stoppers 207 arranged at both ends of the slide rail 201, so as to prevent the first slider 202 from disengaging from the slide rail 201 during use, and a good limiting effect is achieved.
