Description

Technical Field

[0001] The utility model relates to the technical field of automobile stamping production, in particular to a fast-adjustable sheet material bracket assembly. Background Art

[0002] At present, large-scale automated multi-station equipment accounts for a very large proportion in the production of automobile body sheet metal parts. In automated production, in order to accurately position the raw material steel plate before entering the mold cavity, a non-adjustable sheet material support rack assembly device is generally used.

[0003] However, the position of this device is fixed during production, and the position of the lifting frame cannot be adjusted. If the size of the raw material steel plate provided by the customer exceeds the two middle beams and is smaller than the two side beams, the two sides of the raw material steel plate will be suspended, resulting in poor consistency in steel plate positioning and inability to accurately enter the mold cavity, which can easily cause parts to be scrapped and may cause serious tooling accidents such as mold cracking and damage.

[0004] In order to avoid problems such as scrapped parts and tooling accidents, production can only be completed through observation by professional tooling personnel and frequent line stops and adjustments, resulting in a huge waste of manpower and efficiency, and causing great trouble to the production workshop.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1-5 As shown, the utility model provides a fast-adjustable sheet material support rack assembly, including a support rack 3, wherein the bottom end of the support rack 3 is provided with a support leg 4 through bolts, and the support leg 4 is located at one-third of the right side of the support rack 3;

[0026] The bottom of the support frame 3 is provided with a crossbeam 1, and the outer side of the crossbeam 1 is sleeved with a rectangular sleeve 2, the bottom end of the support leg 4 is fixedly connected to the top end of the rectangular sleeve 2, and the rectangular sleeve 2 can slide on the outer end of the crossbeam 1;

[0027] Two pin holes and one threaded hole are provided at both ends of the crossbeam 1, and the crossbeam 1 is installed on the legs of the original non-adjustable sheet material support rack assembly device through the pin holes and the threaded holes;

[0028] Two rows of fixed beams 12 are fixed on the inner wall of the rectangular sleeve 2, and sleeves 13 are provided at the outer ends of the fixed beams 12 through bearing sleeves. The crossbeam 1 is located between the two rows of fixed beams 12, and the sleeve 13 contacts the outer end of the crossbeam 1 to reduce the friction of the rectangular sleeve 2 during sliding.

[0029] The assembly is installed on the legs of the original assembly device through the threaded holes and pin holes at both ends of the crossbeam 1, so that the support frame 3 is located in the gap between the original support frames. The difference is that the original support frames cannot be moved, while the support frame 3 can be moved. By sliding the rectangular sleeve frame 2 on the outer end of the crossbeam 1, the support legs 4 and the support frame 3 can be driven to move, thereby realizing the adjustment of the position of the support frame 3, so as to meet the feeding requirements of raw materials of different sizes, and realizing that when there is a large size difference between the raw material steel plates before and after the mold change, only one adjustment before production is required to ensure production without frequent line stops and adjustments during production, thereby ensuring production efficiency, reducing the waste of man-hours, and reducing the risk of tooling accidents;

[0030] During the sliding process, the sleeve 13 in contact with the crossbeam 1 rolls along with the movement of the rectangular sleeve 2, thereby converting the sliding friction into rolling friction, reducing the friction of the rectangular sleeve 2 during the sliding process, and making the sliding more labor-saving.

[0031] In order to more conveniently fix the position of the rectangular frame 2, as Figure 2 , 5 As shown, a driving seat 10 is fixedly provided at the bottom of the rectangular sleeve frame 2, and a threaded rod 8 is provided on the driving seat 10, penetrating the driving seat 10 and connected to the driving seat 10 by threads.

[0032] One end of the threaded rod 8 is provided with an end plate 11 through a bearing, and the end plate 11 is fixedly arranged at the bottom end of the beam 1. One end of the threaded rod 8 passes through the end plate 11 and is fixedly provided with a knob, and the threaded rod 8 is driven to rotate by rotating the knob.

[0033] When the position of the rectangular frame 2 needs to be adjusted, the knob is turned to drive the threaded rod 8 to rotate. The threaded rod 8 is connected to the driving seat 10 by a thread. Therefore, after the threaded rod 8 rotates, the driving seat 10 will move along the threaded rod 8 and drive the rectangular frame 2 to slide, so as to adjust the position of the rectangular frame 2. After adjustment, the position of the rectangular frame 2 is automatically fixed and will not slide by itself due to external force on the rectangular frame 2 or the legs 4.

[0034] In order to accurately understand the distance adjusted by the rectangular frame 2, as Figure 1 , 3 As shown, a through hole 9 is provided on the support leg 4, and a scale rod 6 is provided on the top of the crossbeam 1. The scale rod 6 passes through the support leg 4 through the through hole 9, and the inner diameter of the through hole 9 is larger than the outer diameter of the scale rod 6;

[0035] One end of the scale rod 6 is provided with a vertical plate 7 by means of bolts. The vertical plate 7 is fixed to the top of the cross beam 1 . The position of the support leg 4 displayed on the scale rod 6 is used to judge the moving distance of the support leg 4 .

[0036] When the rectangular frame 2 and the legs 4 slide on the beam 1, the relative positions of the legs 4 and the scale rod 6 are constantly changing. During the movement of the rectangular frame 2 and the legs 4, the distance moved by the legs 4 can be understood through the scale on the scale rod 6, thereby improving the accuracy of adjustment.

[0037] During use, the forces on both ends of the bracket 3 are not balanced. Figure 1 As shown in , , 2, and 4, a counterweight assembly 5 is provided at the bottom end of the support frame 3, and the counterweight assembly 5 is located on the right side of the support leg 4. The support leg 4 includes a slider 501 arranged at the bottom end of the support frame 3 through a slide rail, and a fastening bolt is provided on the slider 501 through a thread. The position of the slider 501 is adjusted by sliding, and its position is fixed by the fastening bolt.

[0038] A spring 502 is fixedly disposed at the bottom end of the slider 501 , a fixing plate 503 is fixedly disposed at the bottom end of the spring 502 , and a tension rope 504 is fixedly disposed at the bottom end of the fixing plate 503 .

[0039] Since the support leg 4 is installed at the right third of the support frame 3, the lengths of the support frames 3 on both sides of the support leg 4 are different. The longer part of the support frame 3 needs to hold the raw materials during use, so the forces at both ends of the support frame 3 are unbalanced. Therefore, during use, the tension rope 504 can be pulled downward, thereby driving the fixed plate 503 and the spring 502, and the spring 502 is stretched. Then the bottom end of the tension rope 504 is fixed to keep the spring 502 stretched. The elastic force of the spring 502 is used to pull the unstressed end of the support frame 3 downward, so that the forces at both ends of the support frame 3 are balanced, thereby improving the stability of the assembly, and the size of the tension can be adjusted by adjusting the stretching length of the spring 502, and the slider 501 shown in the figure can adjust the force arm of the tension to adapt to raw materials of different weights.

[0040] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
