Description

Technical Field

[0001] This utility model belongs to the field of parts tooling technology, and in particular relates to a tooling fixture for punching holes in a flange. Background Technology

[0002] A flange, also known simply as a flange, is a part consisting of a disc-shaped metal body with several holes around its perimeter for fixing and connecting to other components.

[0003] In the existing flange drilling process, the flange to be drilled is usually fixed on a plane by a tooling fixture. By fixing the drill bit to a rotary motor, the rotary motor drives the drill bit to move along the circumference of the flange, so that multiple holes distributed in its circumferential direction can be drilled on the flange.

[0004] During routine use of the aforementioned tooling fixtures to drill holes in flanges, the applicant discovered that because the holes in the flanges are located at various positions along their circumference, the drill bits also spread across the machining table along with the locations of the holes. This resulted in a high frequency of cleaning the machining table during the entire batch processing, which significantly affected processing efficiency. Therefore, a new solution is needed to improve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a tooling fixture for punching holes in flanges to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a technical solution: a tooling fixture for punching holes in a flange. The tooling fixture is set on a processing table and includes a support table and a rotating assembly for controlling the rotation of the support table. The support table is provided with a center positioning part and a clamping assembly for pressing the workpiece onto the support table. The support table is inclined and the punching position of the workpiece is located below the workpiece.

[0007] Preferably, the clamping assembly includes a drive cylinder and a clamping block located at the output end of the drive cylinder.

[0008] Preferably, the central positioning part is a column, and the flange is sleeved on the central positioning part.

[0009] Preferably, the pressing assembly is disposed on the central positioning part, the central positioning part is provided with a hinge seat, the hinge seat is hinged with a connecting plate, the other end of the connecting plate is hinged to the pressing block, and the pressing block is simultaneously hinged to the output end of the driving cylinder.

[0010] Preferably, at least two sets of the pressure block, hinge seat, and connecting plate are provided.

[0011] Preferably, the tooling fixture further includes a positioning and calibration component mounted on the machining table. The positioning and calibration component includes a drive cylinder and a positioning and calibration pin located at its output end. The positioning and calibration pin can be inserted into the machined hole for positioning to eliminate the cumulative error generated during the rotation of the rotating component.

[0012] Preferably, the central positioning part is provided with a receiving groove for accommodating the drive cylinder.

[0013] Preferably, an extended storage block is provided on the surface of the support platform away from the workpiece, and the receiving groove extends through the extended storage block.

[0014] Preferably, an annular groove is provided on the processing table, and a rolling element is provided in the annular groove, with the support table / extended storage block overlapping the rolling element.

[0015] Preferably, the processing table is provided with a drop groove for the debris to fall off when the drill bit is drilling, and a debris collection box is provided below the drop groove.

[0016] The beneficial effects of this utility model are as follows: This solution controls the rotation of the support table by rotating the component, and at the same time tilts the support table so that the drilling position of the workpiece is located below the workpiece. In this way, the chips generated during processing will slide off naturally, and only a small amount of chips will remain on the processing table within a small area. This can effectively reduce the frequency of cleaning chips on the processing table during the entire batch processing process and effectively improve processing efficiency.

[0017] The connection structure between the hinge seat, connecting plate, pressure block and drive assembly allows the pressure block to rotate, so that the workpiece is not obstructed during insertion and removal.

[0018] Since the rotating component will generate cumulative errors during rotation, the continuous calibration by the positioning and calibration component can effectively ensure the processing accuracy of the product.

[0019] By attaching the support platform / extended storage block to the rolling element, the load on the rotating component can be effectively reduced, thus extending its service life. Attached Figure Description

Detailed Implementation

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention. Example

[0026] See Figure 1 A tooling fixture for drilling flanges is provided. The tooling fixture is set on a processing table 1 and specifically includes a support table 3 and a rotating component 5 for controlling the rotation of the support table 3. The support table 3 is provided with a center positioning part 31 and a clamping component 4 for pressing the workpiece 2 on the support table 3. The support table 3 is inclined and the drilling position of the workpiece 2 is located below the workpiece 2. Specifically, the processing table 1 is arranged in two layers. The rotating component 5 can be a servo motor fixed between the two layers of processing table 1. The upper processing table 1 is arranged parallel to the support table 3 so that the debris generated during processing can slide off the inclined surface of the processing table 1.

[0027] Among them, see Figure 4 The central positioning part 31 is a column, and the flange is sleeved on the central positioning part 31, with its inner ring wall fitting against the circumferential wall of the central positioning part 31 to achieve positioning. The clamping assembly 4 includes a drive cylinder 41 and a pressure block 44 placed at the output end of the drive cylinder 41. The clamping assembly 4 is disposed on the central positioning part 31, and the central positioning part 31 is provided with a hinge seat 42. A connecting plate 43 is hinged to the hinge seat 42, and the other end of the connecting plate 43 is hinged to the pressure block 44. The pressure block 44 is also hinged to the output end of the drive cylinder 41. At least two sets of the pressure block 44, hinge seat 42, and connecting plate 43 are provided and controlled by the same drive cylinder 41.

[0028] Among them, see Figure 2 , Figure 3The tooling fixture also includes a positioning and calibration component fixed on the machining table 1. The positioning and calibration component includes a second drive cylinder 6 and a positioning and calibration pin 61 placed at its output end. The positioning and calibration pin 61 can be inserted into the machined hole for positioning to eliminate the cumulative error generated during the rotation of the rotating component 5. In this embodiment, the positioning and calibration pin is integrated with the output shaft of the second drive cylinder 6. It should be noted that its end is chamfered to facilitate its entry into the hole.

[0029] In this embodiment, the support platform 3 is provided with an extended storage block 32 on the surface away from the workpiece 2, and the central positioning part 31 is provided with a receiving groove that penetrates into the extended storage block 32 to accommodate the driving cylinder 41. The extended storage block 32 in this embodiment is cylindrical.

[0030] Among them, see Figure 2 The processing table 1 has an annular groove 11, and a rolling element is provided in the annular groove 11. The support table 3 / extended storage block 32 is attached to the rolling element, and the rolling element can be a ball bearing or the like.

[0031] The processing table 1 is provided with a drop groove 12 for the debris to fall off when the drill bit is drilling, and a debris collection box 7 is provided below the drop groove 12.

[0032] Working principle and process:

[0033] When using this tooling fixture, place the workpiece 2 on the center positioning part 31, start the equipment, and the clamping component 4 will control the pressure block 44 to rotate and press against the top surface of the workpiece 2 to fix the workpiece 2. Then the drill bit will work to drill a hole. Since the support table 3 and the processing table 1 are both in an inclined state, the drilled debris will fall into the debris collection box 7 below them. After the first hole is drilled, the rotating component 5 drives the support table 3 to rotate the workpiece 2 to the position to process the second hole. At this time, the positioning and calibration component will work first to insert the positioning and calibration pin 61 into the hole that has just been processed to correct the error. Then the drill bit will continue to process, and the above steps will be repeated until the processing is completed. The clamping component 4 will be opened to remove the workpiece 2.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
