Description

Technical Field

[0001] This invention relates to a universal tooling for quick clamping of curved plates, belonging to the field of mechanical processing and manufacturing technology. Background Technology

[0002] In the field of curved plate processing, there are situations where the workpieces vary in arc length, height, and diameter. Currently, when processing curved plate products of different specifications, different specifications of curved molds are often made and clamped with pressure plates to fix the curved plate to be processed, or vacuum adsorption is used to fix the curved plate to be processed. However, when fixing the curved plate to be processed using the above clamping methods, different specifications of clamping fixtures must be made for different specifications of curved plates, and the clamping fixtures that match the curved plates must be disassembled and replaced, which greatly reduces processing efficiency. Therefore, how to achieve the universality of clamping fixtures is a problem that needs to be solved at this stage. Summary of the Invention

[0003] To address the problems associated with clamping during the processing of curved plates, this invention provides a universal tooling for quick clamping of curved plates. This tooling has a simple structure, is easy to assemble and disassemble, and is highly versatile. It can quickly and effectively clamp curved plates of different sizes, improve the processing efficiency of curved plates, and reduce the cost of clamping tooling for curved plates. It has good application prospects in the field of curved plate processing.

[0004] The objective of this invention is achieved through the following technical solutions.

[0005] A universal tooling for quick clamping of curved plates includes a base plate, a long guide rail, a support plate, a short guide rail, a fixed seat, a roller, a corner cylinder, a pressure roller, a locking block, and a locking plate.

[0006] Two long guide rails are installed parallel to each other on the base plate; two parallel support plates are installed perpendicularly on the two long guide rails, and the support plates slide with the long guide rails; locking blocks are fixedly connected to the support plates and the base plate respectively, and are used to fix the position of the support plates on the long guide rails; a short guide rail is installed at one end of the upper surface of each support plate, the two short guide rails are parallel to each other and perpendicular to the long guide rails, and a fixed seat is installed on each short guide rail, which slides with it; a fixed seat is installed at the other end of the upper surface of each support plate; a corner cylinder and a roller are installed on each fixed seat, and a rotatable pressure roller is installed on each corner cylinder, with the pressure roller located above the roller. The roller is used for positioning and supporting the curved plate, while the pressure roller is used for pressing and fixing the curved plate. The curved plate is clamped by the cooperation of the pressure roller and the roller; the locking plate is fixedly connected to the fixed seat, and is used to fix the position of the fixed seat on the short guide rails.

[0007] Furthermore, the tooling also includes a lead screw mechanism for providing power for the sliding of the support plate on the long guide rails; the lead screw mechanism is mounted on the base plate and located between the two long guide rails.

[0008] Furthermore, the lead screw mechanism includes a lead screw seat, a forward and reverse thread adjusting lead screw, and a lead screw nut;

[0009] Two lead screw seats are fixedly installed on the base plate. The two ends of the positive and negative thread adjusting lead screw are installed on the two lead screw seats one by one. The two lead screw nuts are threadedly connected to the positive and negative thread adjusting lead screw, and the two lead screw nuts are fixedly installed on the lower surface of the two support plates one by one.

[0010] Furthermore, the surface on the mounting base for mounting the rotary cylinder is machined into an inclined plane, and the inclination angle of the inclined plane is preferably 30° to 60°.

[0011] Furthermore, a limiting plate is installed on the inner side of each of the two corner cylinders on the short guide rail, and the limiting plate is perpendicular to the central axis of the pressure roller, for limiting and positioning the arc plate in the height direction (or width direction).

[0012] The tooling described in this invention allows for the synchronous adjustment of the position of the support plate on the long guide rail via a lead screw mechanism with forward and reverse thread adjustment, and the fixing of the support plate on the long guide rail with a locking block. This achieves the adjustment of the distance between the two sets of corner cylinders along the length of the long guide rail, thereby enabling the clamping of arc plates with different arc lengths and diameters. Furthermore, by adjusting the position of the fixing seat on the short guide rail and fixing it with a locking plate, the distance between the two sets of corner cylinders along the length of the short guide rail is adjusted, enabling the clamping of arc plates with different heights (or widths), thus achieving the clamping of arc plates of different sizes.

[0013] Beneficial effects:

[0014] (1) The tooling described in this invention can clamp arc plates of different arc lengths, heights and diameters by adjusting the distance between the two sets of corner cylinders in the long guide rail and the distance between the two sets of corner cylinders in the short guide rail. That is, one set of tooling can meet the clamping of arc plates of different sizes. It has strong versatility and the operation of clamping arc plates of different sizes is simple, saving the time of changing traditional tooling and the processing cost of traditional tooling.

[0015] (2) The tooling described in this invention clamps the arc plate with four corner cylinders, which greatly improves the clamping efficiency. Moreover, the clamping of the arc plate with the cooperation of the pressure roller and the support roller can effectively clamp arc plates with different curvatures and avoid damage to the arc plate during the clamping process.

[0016] (3) The present invention designs the cylinder seat as an inclined surface, which, together with the rotatable pressure roller, enables the clamping of arc plates with different curvatures, ensuring that the radial direction of the pressure roller is perpendicular to the inner arc surface of the arc plate, ensuring a secure clamping and reducing the deformation of the arc plate during clamping.

[0017] (4) The limiting plate provided in this invention serves to limit and position the arc plate, making it easier to clamp the arc plate. Moreover, during processing, the end face of the arc plate is attached to the limiting plate, which can provide a positioning reference for processing and ensure the accuracy of arc plate processing.

[0023] Example 1

[0024] A universal tooling for quick clamping of curved plates includes a base plate 1, a long guide rail 2, a support plate 4, a short guide rail 5, a lead screw mechanism, a fixed seat, a support roller 9, a corner cylinder 11, a pressure roller 12, a locking block, a locking plate 13, and a limiting plate 14. Figure 1 As shown;

[0025] A row of fixing threaded holes is machined on the base plate 1 along the length of the long guide rail 2;

[0026] The support plate 4 has through holes machined on it;

[0027] The lead screw mechanism includes a lead screw seat 7, a positive and negative thread adjusting lead screw 6, and a lead screw nut, which are used to provide power for the sliding of the support plate 4 on the long guide rail 2;

[0028] The fixed seat includes a cylinder seat 8 and a roller seat 10, which are connected together by screws. The upper surface of the cylinder seat 8 is machined into an inclined surface with an inclination angle in the range of 30° to 60°. Threaded blind holes are also machined on the side of the cylinder seat 8.

[0029] The upper end of the locking block is machined with threaded blind holes and through holes;

[0030] The locking plate 13 has a screw adjustment groove machined on it;

[0031] Combination Figures 1-3 The assembly relationship between the components in the tooling is as follows: Two long guide rails 2 are mounted on the base plate 1 via guide rail pads 3, and the two long guide rails 2 are parallel to each other; two lead screw seats 7 are fixedly mounted on the base plate 1 and located between the two long guide rails 2; the two ends of the positive and negative thread adjusting lead screws 6 are correspondingly mounted on the two lead screw seats 7, and the positive and negative thread adjusting lead screws 6 are parallel to the long guide rails 2; two lead screw nuts are threadedly connected to the positive and negative thread adjusting lead screws 6, and the two lead screw nuts are correspondingly fixedly mounted on the lower surfaces of the two support plates 4; the two parallel support plates 4 are vertically mounted on the two long guide rails 2, and the support plates 4 and the long guide rails 2 are in sliding fit; after the support plates 4 slide on the long guide rails 2 to the required position, bolts pass through the through holes of the support plates 4 and are threadedly connected to the threaded blind holes of the locking blocks, and screws pass through the through holes of the locking blocks and are threadedly connected to the corresponding fixed threaded holes on the surface of the base plate 1, for fixing the position of the support plates 4 on the long guide rails 2; a short guide rail is installed at one end of the upper surface of each support plate 4. 5. Two short guide rails 5 are parallel to each other and perpendicular to the long guide rail 2. A fixed seat with sliding fit is installed on each short guide rail 5, and a fixed seat is installed at the other end of the upper surface of each support plate 4. A corner cylinder 11 and a roller 9 are installed on each fixed seat. A rotatable pressure roller 12 is installed on each corner cylinder 11, and the pressure roller 12 is located above the roller 9. The roller 9 is used for positioning and supporting the arc plate, while the pressure roller 12 is used for pressing and fixing the arc plate. The curved plate is clamped by the cooperation of the roller 9; after the fixed seat slides to the required position on the short guide rail 5, the bolt passes through the bolt adjustment groove of the locking plate 13 and is threaded to the threaded blind hole on the cylinder seat 8 in the fixed seat to fix the position of the fixed seat on the short guide rail 5; a limiting plate 14 is installed on the inner side of the two corner cylinders 11 on the short guide rail 5 respectively, and the limiting plate 14 is perpendicular to the central axis of the pressure roller 12 to limit and position the curved plate in the height direction (or width direction).

[0032] The principle by which the fixture can clamp arc plates of different sizes is as follows: the position of the support plate 4 on the long guide rail 2 is adjusted synchronously by adjusting the screw 6 of the screw mechanism with positive and negative threads, and the position of the support plate 4 on the long guide rail 2 is fixed by the locking block. This realizes the adjustment of the distance between the two sets of corner cylinders 11 in the length direction of the long guide rail 2, thereby enabling the clamping of arc plates of different arc lengths and diameters. By adjusting the position of the fixed seat on the short guide rail 5 and fixing the position of the fixed seat on the short guide rail 5 with the locking plate 13, the distance between the two sets of corner cylinders 11 in the length direction of the short guide rail 5 is adjusted, thereby enabling the clamping of arc plates of different heights (or widths), that is, enabling the clamping of arc plates of different sizes.

[0033] The operation of clamping the arc plate using the aforementioned tooling is as follows: First, adjust the distance between the front and rear sets of fixed seats in the length direction of the short guide rail 5 according to the height of the arc plate. After adjustment, fix the position of the fixed seat on the short guide rail 5 by locking plate 13. Then, adjust the distance between the left and right support plates 4 in the length direction of the long guide rail 2 simultaneously by adjusting screw 6 according to the arc length of the arc plate, that is, adjust the distance between the left and right sets of fixed seats in the length direction of the long guide rail 2. After adjustment, fix the position of the support plate 4 on the long guide rail 2 by locking block. Then, place the arc plate on the four rollers 9 for positioning, with the rear end face of the arc plate attached to the limiting plate 14 for limiting, and then automatically clamp it by four corner cylinders 11. After that, the processing of the arc plate begins.

[0034] In summary, the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
