Description

Technical Field

[0001] This utility model belongs to the technical field of positioning clamps, and in particular relates to an adjustable plate positioning clamp. Background Technology

[0002] In sheet metal processing, drilling is a common process, and accurate positioning and fixing of the sheet metal are crucial to ensuring drilling precision. Traditional fixtures mostly employ fixed structures, which are only suitable for sheets of specific sizes or shapes, resulting in poor versatility. When the sheet metal dimensions change, frequent adjustments or replacements of the fixtures are required, leading to low efficiency, and positioning accuracy is easily affected by human factors. Furthermore, uneven clamping force distribution in some fixtures can easily cause sheet metal displacement or deformation, affecting drilling quality.

[0003] While some adjustable fixtures exist in the existing technology, their complex structures and cumbersome adjustment procedures make them difficult to quickly adapt to the processing requirements of different sheet metal specifications. Furthermore, insufficient rigidity or poor clamping stability of the fixtures can lead to sheet metal vibration during drilling, reducing processing accuracy.

[0004] Therefore, there is an urgent need for a plate positioning fixture that is simple in structure, easy to adjust, stable in positioning, and widely applicable, in order to improve the efficiency and quality of drilling. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable plate positioning clamp to address the shortcomings of existing technologies.

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely exemplary embodiments of this utility model, and not the only embodiments.

[0019] like Figures 1 to 10As shown, an adjustable plate positioning clamp includes a base plate 1. A first limiting block 2 and a second limiting block 3 are fixedly mounted at both ends of the surface of the base plate 1, respectively. In actual use, a plate 26 is placed on the base plate 1, and both ends of the plate 26 are clamped by the first limiting block 2 and the second limiting block 3 to fix the plate 26 onto the base plate 1. The surfaces of the first limiting block 2 and the second limiting block 3 are each provided with several locking holes 4. A first pressure plate 5 and a second pressure plate 6 are respectively installed between the front and rear ends. The two ends of the first pressure plate 5 are slidably engaged with and locked relative to the first limiting block 2 and the second limiting block 3 by a first locking block 7. The two ends of the second pressure plate 6 are slidably engaged with and locked relative to the first limiting block 2 and the second limiting block 3 by a second locking block 8 with the same structure as the first locking block 7. The bottom of the first locking block 7 has a bayonet 9, which abuts against the side end of the first pressure plate 5. The surface of the first locking block 7 has a slot 10, through which the fixing member 11 passes in sequence. The locking hole 4 allows the first locking block 7 to slide and lock relative to the first limiting block 2 and the second limiting block 3, respectively. Specifically, the fixing member 11 passes through the slot 10 and the locking hole 4 in sequence to allow the first locking block 7 to slide and lock relative to the first limiting block 2, and the fixing member 11 passes through the slot 10 and the locking hole 4 in sequence to allow the first locking block 7 to slide and lock relative to the second limiting block 3. This achieves that both ends of the first pressure plate 5 slide and lock relative to the first limiting block 2 and the second limiting block 3, respectively. Similarly, the fixing member 11... The fastener 11 passes through the slot 10 and the lock hole 4 in sequence so that the second locking block 8 slides and locks with the first limiting block 2 and the second limiting block 3 respectively. Specifically, the fastener 11 passes through the slot 10 and the lock hole 4 in sequence so that the second locking block 8 slides and locks with the first limiting block 2. The fastener 11 passes through the slot 10 and the lock hole 4 in sequence so that the second locking block 8 slides and locks with the second limiting block 3 respectively. Thus, the two ends of the second pressure plate 6 slide and lock with the first limiting block 2 and the second limiting block 3 respectively.

[0020] Specifically, after the plate 26 is placed on the base plate 1, the first limiting block 2 and the second limiting block 3 first press and fix the two sides of the plate. Then, the position of the plate 26 is adjusted according to the actual processing requirements of the plate 26. When the position of the plate 26 is relatively fixed, the two ends of the first pressure plate 5 are placed on the first limiting block 2 and the second limiting block 3 respectively. Then, the latch 9 of the first locking block 7 abuts against the side end of the first pressure plate 5. Then, the first locking block 7 is fixed on the first limiting block 2 and the second limiting block 3 by the fastener 11 passing through the slot 10 and the locking hole 4. This completes the longitudinal compression of the plate 26 by the first pressure plate 5. Similarly, the two ends of the second pressure plate 6 are placed on the first limiting block 2 and the second limiting block 3 respectively. Then, the latch 9 of the second locking block 8 is abutted against the side end of the second pressure plate 6. The second locking block 8 is then fixed to the first limiting block 2 and the second limiting block 3 by the fastener 11 passing through the slot 10 and the locking hole 4. This completes the longitudinal compression of the plate 26 by the second pressure plate 6. Thus, under the combined action of the first limiting block 2, the second limiting block 3, the first pressure plate 5, and the second pressure plate 6, the plate 26 is compressed. The first locking block 7 is firmly fixed to the base plate 1, thus securing the base plate 1 with a clamp and facilitating subsequent processing of the sheet metal 26. When it is necessary to adjust the position of the sheet metal 26 on the base plate 1, the fixing member 11 on the first pressure plate 5 is loosened, and the position of the first locking block 7 is moved and adjusted along the first limiting block 2 or the second limiting block 3. When adjusted to the predetermined position, the latch 9 of the first locking block 7 abuts against the first pressure plate 5 again, and then the fixing member 11 passes through the slot 10 and the locking hole 4 to fix the first locking block 7 on the first limiting block 2 and the second limiting block 3. Similarly, if The position of the second pressure plate 6 needs to be adjusted. Loosen the fixing piece 11 on the second pressure plate 6 and move the position of the second locking block 8 along the first limiting block 2 or the second limiting block 3. When it is adjusted to the predetermined position, make the bayonet 9 of the second locking block 8 abut against the second pressure plate 6 again. Then, fix the second locking block 8 on the first limiting block 2 and the second limiting block 3 by passing the fixing piece 11 through the slot 10 and the locking hole 4. In this way, the position adjustment of the first pressure plate 5 or the second pressure plate 6 on the first limiting block 2 and the second limiting block 3 is completed. This process is simple and quick.

[0021] like Figure 2 As shown, a gasket 12 is provided on the surface of the slot 10. The gasket 12 is used to increase the friction when the fastener 11 passes through the slot 10, thereby enhancing the fastening effect of the fastener 11.

[0022] like Figure 3 As shown, the first limiting block 2 and the second limiting block 3 are both provided with mounting holes 13 that penetrate the base plate 1. Fasteners 14 pass through the mounting holes 13 to fix the first limiting block 2 and the second limiting block 3 to the base plate 1 respectively.

[0023] As mentioned above, after the plate 26 is placed on the base plate 1, the first pressure plate 5 and the second pressure plate 6 apply longitudinal pressure to the surface of the plate 26 to ensure that the plate 26 can be firmly fixed on the base plate 1. To further strengthen the longitudinal pressure of the first pressure plate 5 and the second pressure plate 6 on the surface of the plate 26, such as... Figure 4 and Figure 5 As shown, both the first pressure plate 5 and the second pressure plate 6 are provided with a number of fixing holes 15, and bolts 16 are installed on some of the fixing holes 15. After the two ends of the first pressure plate 5 and the two ends of the second pressure plate 6 are fixed on the first limiting block 2 and the second limiting block 3 respectively, the bolts 16 pass through the fixing holes 15 and the bottom end of the bolts 16 contacts the surface of the plate 26 to apply pressure, ensuring that the plate 26 will not move on the base plate 1 and is firmly fixed on the base plate 1. It can be understood that the number of bolts 16 depends on the size and area of ​​the plate 26. In actual operation, the number of bolts 16 used can be determined according to the size and area of ​​the plate 26.

[0024] Because there is a certain space between the first pressure plate 5 and the second pressure plate 6, after the sheet material 26 is placed on the base plate 1, the first pressure plate 5 and the second pressure plate 6 will apply pressure to both ends of the surface of the sheet material 26. However, the middle area of ​​the surface of the sheet material 26 lacks longitudinal pressure. This may cause the middle area of ​​the surface of the sheet material 26 to bulge upward, resulting in an uneven surface of the sheet material 26, which will affect the subsequent processing of the sheet material 26. For this reason, fastening components are installed on both the first limiting block 2 and the second limiting block 3. The fastening components are located between the first pressure plate 5 and the second pressure plate 6. Figure 1 , Figure 3 As shown, the fastening assembly includes a fastening strip 17 and a fastening screw 18. The fastening strip 17 has a mounting groove 19 that mates with the locking hole 4. The fastening screw 18 passes through the mounting groove 19 and the locking hole 4 in sequence to allow the fastening strip 17 to slide and lock relative to the first limiting block 2 or the second limiting block 3. Specifically, after the plate 26 is placed on the base plate 1, the first limiting block 2 and the second limiting block 3 press against both ends of the plate 26 to form a preliminary fixation. The first pressure plate 5 and the second pressure plate 6 longitudinally press against both ends of the surface of the plate 26 to fix it. Then, the fastening screw 18 passes through the mounting groove 19 and the locking hole 4 to secure the fastening strip 17. 7. The fastening strip 17 is fixed to the first limiting block 2, or the fastening screw 18 passes through the mounting groove 19 and the locking hole 4 to fix the fastening strip 17 to the second limiting block 3. This completes the application of longitudinal pressure to the middle area of ​​the surface of the plate 26 by the fastening assembly, so that the plate 26 is more firmly fixed to the base plate 1. In order to further realize the position fixation of the fastening strip 17 on the surface of the plate 26, slots 21 are provided at both ends of the fastening strip 17. The bolt 25 passes through the slot 21 and the bottom end of the bolt 25 contacts the surface of the plate 26 so that the bolt 25 applies longitudinal pressure to the surface of the plate 26, thereby completing the fixation of the middle area of ​​the surface of the plate 26.

[0025] When it is necessary to adjust the position of the fastening strip 17 on the first limit block 2 or the second limit block 3, loosen the fastening screw 18, move the fastening strip 17 to the predetermined position, and then fix the fastening strip 17 to other positions of the first limit block 2 or the second limit block 3 by passing the fastening screw 18 through the mounting groove 19 and the locking hole 4.

[0026] like Figure 3 As shown, a washer 20 is provided on the fastening screw 18. The washer 20 is located on the surface of the mounting groove 19. The washer 20 is used to increase the friction when the fastening screw 18 passes through the mounting groove 19, thereby enhancing the fixing effect of the fastening screw 18.

[0027] like Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, a stop block 22 is also fixedly installed on the end of the surface of the base plate 1. The stop block 22 is set at 90° with the first limiting block 2 and the second limiting block 3 on the base plate 1. After the plate 26 is placed on the base plate 1, in addition to the first limiting block 2 and the second limiting block 3 pressing and fixing its two ends, the other end of the plate 26, that is, the end that forms a 90° angle with the first limiting block 2 and the second limiting block 3, also needs to be limited and fixed. Therefore, this function can be achieved by setting the stop block 22.

[0028] The block 22 has several connecting holes 23 that penetrate the base plate 1. The fixing screws 24 pass through the connecting holes 23 to fix the block 22 to the base plate 1. This arrangement can fix the block 22 to the base plate 1.

[0029] A drilling machine includes an adjustable plate positioning clamp. After the plate 26 is fixed on the base plate 1 using the above-mentioned technical solution, the drilling machine performs drilling operations on it.

[0030] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
