Description

Technical Field

[0001] This utility model relates to the field of plate straightening equipment technology, and more specifically, to a tooling fixture for straightening plate. Background Technology

[0002] A steel plate straightening machine is a device that automatically straightens and detects the levelness of steel plates. For example, Chinese Patent No. CN220295538U discloses a steel plate straightening device, which is a common type of steel plate straightening machine. During the straightening process, tooling fixtures are needed to flip the steel plates. Existing tooling fixtures cannot clamp steel plates of different widths and thicknesses, and different tooling fixtures are required to clamp different steel plates, which is costly. Therefore, in view of this situation, this utility model ingeniously proposes a tooling fixture for straightening flat plates to solve the shortcomings in the above-mentioned technical background. Utility Model Content

[0003] The present invention aims to solve the problem that the clamps in existing straightening machines cannot clamp and flip steel plates of different widths and thicknesses.

[0004] The purpose and effect of this utility model of a tooling fixture for calibrating a flat plate are achieved by the following specific technical means: A tooling fixture for calibrating a flat plate includes a clamping frame, a resetting longitudinal adjustment block vertically slidably connected inside the clamping frame, and a resetting transverse adjustment block horizontally slidably connected inside the clamping frame. Several connecting rods are fixedly connected to both the longitudinal and transverse adjustment blocks. The connecting rods extend outward through the clamping frame, and corresponding push plates are fixedly connected to the outer ends of the connecting rods. Sliding frames are slidably connected to the four walls of the clamping frame, and fixed pulleys are fixedly connected to the four corners of the clamping frame. Pulley lines are fixedly connected to the sliding frames, and the sliding frames are connected end to end in sequence after turning at the fixed pulleys. A positioning mechanism is provided on the sliding frame on the upper side of the clamping frame to limit the movement of the sliding frame. Several snap-fit ​​strips arranged in a straight line are fixedly connected to the connecting rods, and corresponding snap-fit ​​grooves are provided on the sliding frames.

[0005] Furthermore, the positioning mechanism includes a positioning rod, and a positioning rod that can be vertically slidably reset is provided in the sliding frame located on the upper side of the clamping frame. A positioning hole is provided in the upper wall of the clamping frame, and the positioning rod is inserted into the positioning hole.

[0006] Furthermore, a handle is fixed to the positioning rod.

[0007] Furthermore, both the snap-fit ​​groove and the snap-fit ​​strip are angled.

[0008] Furthermore, the ends of the snap-fit ​​groove are chamfered.

[0009] Furthermore, the upper wall of the clamping frame is provided with several positioning holes at different positions.

[0010] Furthermore, two central gears are rotatably connected in the clamping frame, and two corresponding racks are slidably connected to the sides of each central gear. The racks are meshed with the central gears. The two racks that mesh with one of the central gears are laterally slidable, and the two racks that mesh with the other central gear are longitudinally slidable. The four racks are fixed to the corresponding push plates by connecting rods.

[0011] Furthermore, protective pads are fixed to the inner side of both the lateral and longitudinal adjusting blocks.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model provides a tooling fixture for calibrating a flat plate. By moving a push plate to connect the horizontal and vertical adjustment blocks with the steel plate, and then moving a sliding frame to fix the horizontal and vertical adjustment blocks, the horizontal and vertical adjustment blocks move outward a certain distance during this process, so that the end of the steel plate can be inserted into it and clamped. This allows for quick movement of the horizontal and vertical adjustment blocks to adapt to steel plates of different thicknesses and widths, so that this tooling fixture can clamp and flip different steel plates.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] As attached Figure 1 To be continued Figure 5 As shown: A tooling fixture for straightening a flat plate includes a clamping frame 1, which is disposed on both sides of a straightening machine, i.e., clamping frames 1 are provided on both the left and right sides of the straightening machine; a resettable longitudinal adjusting block 2 is vertically slidably connected inside the clamping frame 1, and a resettable transverse adjusting block 3 is horizontally slidably connected inside the clamping frame 1; several connecting rods 4 are fixedly connected to both the longitudinal adjusting block 2 and the transverse adjusting block 3, and the connecting rods 4 extend outward through the clamping frame 1; a corresponding push plate 5 is fixedly connected to the outer end of the connecting rod 4. Specifically, the push plate 5... The clamping frame 1 is equipped with four adjustment blocks: longitudinal adjustment block 2 and transverse adjustment block 3, which are slidably connected to the clamping frame 1 via connecting rods 4. A return spring is fixedly connected between the corresponding push plate 5 and the clamping frame 1, providing elastic force for the transverse adjustment block 3 and longitudinal adjustment block 2 to slide inwards. Sliding frames 6 are slidably connected to the four side walls of the clamping frame 1, and fixed pulleys 7 are fixedly connected to the four corners of the clamping frame 1. The sliding frames 6 on the clamping frame 1 are fixedly connected to pulley lines 8, and the sliding frames 6 use the pulley lines 8 to... After turning at the fixed pulley 7, they are connected end to end in sequence, so that when one sliding frame 6 slides, it drives all sliding frames 6 to move the same distance. A positioning mechanism is provided on the sliding frame 6 on the upper side of the clamping frame 1. The positioning mechanism is used to fix the sliding frame 6 so that it does not move. Several snap-fit ​​strips 401 arranged in a row are fixed on the connecting rod 4. The sliding frame 6 is provided with corresponding snap-fit ​​grooves 9. Through the snap-fit ​​grooves 9 and snap-fit ​​strips 401, the positions of the longitudinal adjusting block 2 and the transverse adjusting block 3 are fixed. Thus, by adjusting the positions of the longitudinal adjusting block 2 and the transverse adjusting block 3, steel plates of different thicknesses and widths can be clamped. In one embodiment, the end of the steel plate is inserted into the clamping frame 1. The transverse adjusting block 3 and the longitudinal adjusting block 2 are connected to the edge of the steel plate by pushing the push plate 5. Then the sliding frame 6 is moved so that the snap-fit ​​grooves 9 and snap-fit ​​strips 401 are engaged. Thus, the positions of the transverse adjusting block 3 and the longitudinal adjusting block 2 can be fixed, so that the transverse adjusting block 3 and the longitudinal adjusting block 2 can be adapted to the thickness of the steel plate for clamping and flipping.

[0022] Among them, such as Figures 1 to 2As shown, the positioning mechanism includes a positioning rod 10. The sliding frame 6 located on the upper side of the clamping frame 1 has a positioning rod 10 that can be vertically slidably reset. Specifically, a reset spring can be set between the positioning rod 10 and the sliding frame 6 to realize the sliding reset of the positioning rod 10. The upper wall of the clamping frame 1 has a positioning hole 12, which is correspondingly set with the positioning rod 10. The lower end of the positioning rod 10 is inserted into the positioning hole 12, thereby restricting the movement of the sliding frame 6.

[0023] Among them, such as Figure 2 As shown, a handle 11 is fixedly connected to the positioning rod 10, which facilitates the movement of the sliding frame 6.

[0024] Among them, such as Figures 2 to 5 As shown, both the snap-fit ​​groove 9 and the snap-fit ​​strip 401 are inclined. During the snap-fit ​​process of the snap-fit ​​groove 9 and the snap-fit ​​strip 401, due to the inclined setting, the horizontal adjustment block 3 or the vertical adjustment block 2 can be moved outward a little distance before being fixed, so that the steel plate can be more easily inserted and clamped between the horizontal adjustment block 3 and the vertical adjustment block 2.

[0025] Among them, such as Figure 4 As shown, the end of the snap-fit ​​groove 9 is provided with a chamfer 901, which facilitates the insertion of the snap-fit ​​strip 401.

[0026] Among them, such as Figure 2 As shown, a number of positioning holes 12 are provided on the upper wall of the clamping frame 1. The sliding distance of the sliding frame 6 can be different by the different positions of the positioning holes 12, and the horizontal adjusting block 3 and the vertical adjusting block 2 can be moved outward by different distances and then fixed according to actual needs.

[0027] Among them, such as Figures 1 to 3 As shown, two central gears 15 are rotatably connected in the clamping frame 1. The two central gears 15 are coaxially arranged but do not rotate on the same axis. Two corresponding racks 14 are slidably connected to the sides of each central gear 15, and the racks 14 mesh with the central gears 15. Specifically, the two racks 14 that mesh with one of the central gears 15 are laterally slidable, and the two racks 14 that mesh with the other central gear 15 are longitudinally slidable. The four racks 14 are respectively fixed to the corresponding push plates 5 by connecting rods 4. Through the arrangement of the central gears 15 and racks 14, the two lateral adjusting blocks 3 can move inward by the same distance, and the two longitudinal adjusting blocks 2 can also move inward by the same distance. Thus, the steel plate can be clamped in the center position of the clamping frame 1 by the lateral adjusting blocks 3 and the longitudinal adjusting blocks 2, so that the steel plate remains in its original position after being flipped.

[0028] Among them, such as Figure 2As shown, protective pads 13 are fixed to the inner side of the horizontal adjustment block 3 and the vertical adjustment block 2, and the protective pads 13 are in contact with the steel plate. By setting the protective pads 13, the horizontal adjustment block 3 and the vertical adjustment block 2 are prevented from directly contacting the steel plate and causing scratches.

[0029] Working principle: The two ends of the steel plate are placed into the corresponding clamping frames 1. Then, the push plate 5 quickly moves the horizontal adjusting block 3 and the vertical adjusting block 2. Due to the action of the central gear 15 and the rack 14, the two horizontal adjusting blocks 3 move inward by the same distance, and the two vertical adjusting blocks 2 move inward by the same distance. This allows the end of the steel plate to move to the center position of the clamping frame 1, so that the steel plate remains in its original position after being flipped. After the horizontal adjusting block 3 and the vertical adjusting block 2 contact and clamp the steel plate, the sliding frame 6 is moved to make the locking strip 401 engage with the locking strip 401. Both the horizontal adjustment block 3 and the vertical adjustment block 2 are inclined, which allows them to move slightly outward when their positions are restricted, thus facilitating the insertion of the steel plate into the clamping frame 1 for clamping. The positioning rod 10 is inserted into the positioning hole 12, which restricts and fixes the position of the sliding frame 6, thereby restricting and fixing the positions of all the horizontal adjustment blocks 3 and the vertical adjustment blocks 2. By adjusting the positions of the horizontal adjustment blocks 3 and the vertical adjustment blocks 2, the clamping frame 1 can clamp steel plates of different thicknesses and widths, avoiding the need to replace different clamps and the resulting high cost.
