Technical Field

[0001] The utility model belongs to the technical field of machining positioning devices, and particularly relates to a cold-rolled plate machining positioning device which is easy to adjust. Background Art

[0002] The punching, welding and other steps involved in the cold-rolled plate processing process require the use of a positioning device to position the cold-rolled plate to ensure that the cold-rolled plate will not be displaced during the processing and to ensure its processing accuracy. In the actual processing process, due to the different sizes of the plates to be processed, it is necessary to center them to determine the coordinate origin of the program when using CNC equipment for processing. The positioning device of the prior art uses single-sided positioning, and the positioning edge is fixed and cannot be adaptively adjusted according to the size of the plate. As a result, after each replacement of plates of different sizes, the X and Y directions need to be re-centering (machine tool processing origin setting), which is troublesome and time-consuming, affecting processing efficiency. Therefore, there is a certain market demand for designing a cold-rolled plate processing positioning device that is easy to adjust the positioning edge. Summary of the invention

[0016] In order to better understand the present invention, Figure 1 to Figure 2 The implementation modes of the present utility model will be explained in detail.

[0017] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all based on Figure 1 The "front, back, left, right, up, and down" directions in the text are based on the "front, back, left, right, up, and down" directions, and the "X, Y" directions mentioned in the text refer to the Cartesian coordinate system directions, that is, the X direction is Figure 1 The left and right directions in the Y direction are Figure 1 The front-to-back direction.

[0018] See also Figure 1 and Figure 2The utility model is a cold-rolled plate processing positioning device that is easy to adjust, comprising a base 1, a positioning platform 2 is arranged on the base 1, a clamping plate 3 is slidably arranged on both sides of the left and right sides of the positioning platform 2, a telescopic mechanism 4 is arranged on the base 1, the telescopic mechanism 4 is a hydraulic cylinder, two pull rods 5 are hingedly arranged on the telescopic end of the telescopic mechanism 4, the two pull rods 5 are respectively hinged to the bottom of a clamping plate 3, the positioning platform 2 is provided with a front and rear slide rail (Y direction) located above the telescopic mechanism 4, a limit stopper 7 is slidably arranged in the front and rear slide rails, and a locking portion 8 is arranged between the limit stopper 7 and the front and rear slide rails.

[0019] The preferred technical solution in this embodiment is that in order to position the plate in the up and down directions, each of the clamping plates 3 is telescopically provided with a vertical rod 10 that passes through the vertical rod 10, the top of the vertical rod 10 is provided with a clamping claw 11, and the bottom of the vertical rod 10 is hinged to one of the pull rods 5.

[0020] The preferred technical solution in this embodiment takes into account that the size of the plate as a raw material may have errors, resulting in asymmetric cutting edges on both sides of the plate, making the plate a trapezoid. In this regard, clamping only by the clamping plate 3 may not be in place, resulting in displacement or even flying parts during processing. Therefore, the clamping plate 3 is designed as a structure that can be corrected for offset. Specifically: the clamping plate 3 also includes two sliders 12 hinged at the front and rear ends, and the positioning platform 2 is provided with a linear guide 13 (X direction) compatible with the slider 12, and the vertical rod 10 is arranged on the slider 12; the telescopic mechanism 4 is provided with two, and the two pull rods 5 at the telescopic end of each telescopic mechanism 4 are respectively hinged to the bottom of the left and right vertical rods 10, and a spreading spring 14 is provided between the vertical rod 10 and the slider 12.

[0021] In the preferred technical solution of this embodiment, in order to prevent the clamping jaws 11 from crushing the surface of the plate, a rubber pad is provided at the bottom of the clamping jaws 11 .

[0022] The preferred technical solution in this embodiment is that the front and rear slide rails are T-shaped slide rails 15, and a matching T-block 16 is arranged in the T-shaped slide rail 15. The T-block 16 is connected to the limit stop block 7, and the locking part 8 is arranged between the T-shaped slide rail 15 and the T-block 16.

[0023] In the preferred technical solution of this embodiment, the locking portion 8 is a bolt, which passes through the limit stop 7 and is threadedly connected to the T block 16. The limit stop 7 and the T block 16 are adjusted to a loose or tight state in the front and rear slide rails by loosening or tightening the bolt.

[0024] The preferred technical solution in this embodiment is that the positioning platform 2 is provided with a scale located on one side of the front and rear slide rails and cooperates with the limit block 7, and the 0 point (starting point) of the scale is located in the middle of the positioning platform 2, that is, at the midpoint of the positioning platform 2.

[0025] The usage and principle of the utility model are as follows: first, the position of the limit stopper 7 is adjusted according to the size of the plate to be processed, and the limit stopper is fixed by the locking part 8; then, the plate to be processed is placed on the positioning platform 2 and abuts against the limit stopper 7; then, the two telescopic mechanisms 4 are started to shrink, and the pull rods 5 drive the hinged vertical rods 10 on the left and right sides to slide up and down the slider 12 through the shrinkage of their respective telescopic ends. During this period, the elastic force of the rear support spring of the vertical rod 10 slows down the sliding speed, causing the pulling force of the pull rod 5 to be transmitted to the slider 12, driving the sliders 12 on the left and right sides to slide toward the middle, and at the same time, the splint 3 hinged between the front and rear sliders 12 also slides toward the middle synchronously until the two sides abut and clamp the left and right sides of the plate in the middle; finally, the pull rod 5 continues to apply pulling force to the vertical rod 10, so that the clamping claws 11 at the top of the pull rod 5 press the top surface of the plate to achieve the positioning of the plate.

[0026] When the plate needs to be released from positioning, the two telescopic mechanisms 4 are activated to expand and reset, and the slide block 12 and the vertical rod 10 are driven to reset through the movement of the pull rod 5, thereby releasing the positioning state of the plate.
