Technical Field

[0001] This invention relates to the field of workpiece processing technology, and in particular to a method for fixing irregularly shaped workpieces during processing. Background Technology

[0002] Irregularly shaped workpieces refer to workpieces with irregular outer surface shapes. They usually adopt non-traditional geometric shapes and may have special shapes or surfaces such as curved surfaces, asymmetrical contours, and uneven shapes. They are widely used in aerospace, machine manufacturing and other fields.

[0003] The basic structural form of irregularly shaped workpieces is that both ends are fixed with circular end frames, and irregularly shaped surface structures are set between the end frames. Irregularly shaped surface structures usually have characteristics such as thin walls and irregular shapes, which are difficult to clamp and bring difficulties to the processing of irregularly shaped workpieces.

[0004] In the existing technology, the processing of irregular workpieces requires technicians to measure and scribing, determine the processing benchmark, and align them by manual hammering and other methods. The operation is complicated, the steps are cumbersome, the processing time is long, and the technicians' experience is highly required, which seriously affects the processing efficiency of irregular workpieces. Summary of the Invention

The arc-shaped plate is connected to the sliding end through the support rod. The sliding end is disposed within the arc-shaped groove.

[0025] Furthermore, the top plate also includes arc-shaped positioning blocks and a second adjusting component. Multiple arc-shaped positioning blocks form a circular structure. The second adjusting component includes a top gear disk, a second driving gear, a second drive rod, and a rocker handle. The top gear disk and the second driving gear are connected to the top plate through bearing seats. The second driving gear meshes with the top gear disk. The second drive rod is connected to the second driving gear and passes through the top plate to connect with the rocker handle. The top gear disk is provided with positioning arc grooves, the number of which is the same as the number of arc-shaped positioning blocks. The arc-shaped positioning blocks are provided with connecting rods and moving ends. The arc-shaped positioning blocks are connected to the moving ends through connecting rods. The moving ends are located in the positioning arc grooves. When the top gear disk rotates, the moving ends move along the positioning arc grooves.

[0026] Furthermore, in step S4, the irregular workpiece fixing device also includes a fixing detection component.

[0031] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0032] (1) The irregular workpiece processing and fixing method provided by the present invention can quickly align and position the workpiece by using an irregular workpiece fixing device. By rotating the first drive rod, the first drive gear can be rotated, thereby driving the bottom gear disk to rotate. When the bottom gear disk rotates, the sliding end moves along the arc-shaped groove, driving the arc plate to move with the sliding end, making the circular structure formed by the arc plate larger or smaller, so that the arc plate is tightly attached to the inner wall of the bottom frame, and the arc plate can cooperate with the bottom frame of different workpieces to align the workpiece. Rotating the rocker arm can drive the second drive rod to rotate, thereby driving the second drive gear to rotate the top gear disk. When the top gear disk rotates, the moving end moves along the positioning arc groove, driving the arc positioning block to move with the moving end, making the circular structure formed by the arc positioning block larger or smaller, so that the arc plate is tightly attached to the inner wall of the top frame, and the irregular workpiece fixing device can align workpieces of different diameters, and has universality. The workpiece can be aligned using curved plates and curved positioning blocks, eliminating the need for manual marking, hammering, or other methods. This saves a significant amount of manpower, is simple to operate, and allows for quick alignment and positioning of the workpiece, thereby improving processing efficiency.

[0033] (2) In the irregular workpiece processing and fixing method provided by the present invention, in step S4, the stability of the workpiece fixing is checked, and the tension nut is adjusted to make the workpiece firmly fixed. Step S4 can improve the stability and safety of the workpiece fixing device, thereby reducing the risk of workpiece damage due to unstable fixing. By setting a fixing detection component, the stability of the workpiece fixing can be quickly detected, saving manpower, improving processing efficiency, and shortening the time for detecting the stability of the workpiece fixing. When testing the stability of the workpiece fixing, the workpiece is tilted. If the workpiece is not firmly fixed, the workpiece will shift under the tilting action, causing a gap between the bottom frame and the bottom plate. The pressing ball at the gap protrudes out of the spherical hole under the action of the support spring, allowing the column to enter the column hole. Technicians only need to observe whether the column protrudes out of the column hole to determine the workpiece fixing status, thereby adjusting the tension nut. The operation is simple, easy to observe, saves manpower, and improves processing efficiency.

[0034] (3) The irregular workpiece processing and fixing method provided by the present invention improves the efficiency of fixing and aligning irregular workpieces by using the irregular workpiece fixing device, saving manpower; the workpiece is fixed and aligned by the arc plate and arc positioning block, improving the accuracy of workpiece alignment and fixing, eliminating the need for manual measurement, reducing human error, and improving the precision of irregular workpiece processing. The stability of workpiece fixing is further improved by fixing the open end frame by the pressure plate assembly. Step S4 can adjust the unstable fixing parts, improving the safety and stability of irregular workpiece processing. Step S6 can recycle the irregular workpiece fixing device for use in the next processing, saving costs. The irregular workpiece processing and fixing method of the present invention can save a lot of manual operation, eliminate the need for scribing and measurement, reduce human error, improve processing efficiency, effectively improve the safety and stability of irregular workpiece processing, and can adapt to irregular workpieces of different diameters, with good economic benefits.

Detailed Implementation

[0048] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of the present invention and are used together with the invention to illustrate the principles of the invention.

[0049] This embodiment provides a method for fixing irregularly shaped workpieces during processing, employing an irregularly shaped workpiece fixing device, such as... Figure 1As shown, it includes the following steps:

[0050] S1: Adjustment of workpiece fixing device;

[0051] S2: Fixed opening end frame 73;

[0052] S3: Fasten workpiece 7;

[0053] S4: Check the stability of the fixation;

[0054] S5: Process workpiece 7;

[0055] S6: Separate workpiece 7 from the irregular workpiece fixing device.

[0056] like Figure 2 As shown, the workpiece 7 includes a bottom frame 71, a top frame 72, and an open end frame 73. The irregular workpiece fixing device includes a base 1, a top plate 2, and a tension connector 3. The workpiece 7 is placed between the top plate 2 and the base 1. The base 1 and the top plate 2 are connected by the tension connector 3, so that the top plate 2 presses the workpiece 7, thereby fixing the workpiece 7.

[0057] Furthermore, such as Figure 3 As shown, the base 1 includes an arc-shaped plate 11, a base plate 12, a first adjusting member 13, and a positioning block 14. Multiple arc-shaped plates 11 are provided, forming a circular structure. The arc-shaped plates 11 are connected to the base plate 12 and the first adjusting member 13. The positioning block 14 is connected to the base plate 12. The first adjusting member 13 is disposed inside the positioning block 14, and the position of the arc-shaped plate 11 can be adjusted through the first adjusting member 13. The tension connecting member 3 is disposed on the positioning block 14.

[0058] Preferably, a slider is provided on the arc plate 11 and a slide rail is provided on the base plate 12. The arc plate 11 and the base plate 12 are connected by the slider and the slide rail, thereby increasing the stability of the movement of the arc plate 11.

[0059] In step S1, specifically, the workpiece 7 is placed on the base 1, and the position of the arc plate 11 is adjusted by the first adjusting member 13 so that the arc plate 11 is in close contact with the inner wall of the bottom frame 71 of the workpiece 7, thereby aligning the workpiece 7.

[0060] Furthermore, the first adjusting member 13 includes a bottom gear disk 131, a first driving gear 132, and a first driving rod 133. The bottom gear disk 131 and the first driving gear 132 are connected to the positioning block 14 through a bearing seat. The first driving gear 132 meshes with the bottom gear disk 131, and the first driving rod 133 is connected to the first driving gear 132. By rotating the first driving rod 133, the first driving gear 132 can be rotated, thereby driving the bottom gear disk 131 to rotate. The bottom gear disk 131 is provided with an arc-shaped sliding groove 1311. The number of arc-shaped sliding grooves 1311 is the same as that of the arc-shaped plate 11. The arc-shaped plate 11 is provided with a support rod 111 and a sliding end 112. The arc-shaped plate 11 is connected to the sliding end 112 through the support rod 111. The sliding end 112 is located in the arc-shaped sliding groove 1311. When the bottom gear disk 131 rotates, the sliding end 112 moves along the arc-shaped sliding groove 1311, which drives the arc-shaped plate 11 to move with the sliding end 112, so that the circular structure formed by the arc-shaped plate 11 increases or decreases, thereby making the arc-shaped plate 11 fit tightly against the inner wall of the bottom frame 71.

[0061] Preferably, the base 1 is provided with multiple stepped positioning pins, the positions of which correspond to the positions of the pin holes on the workpiece 7, thereby positioning the workpiece 7 in the circumferential direction.

[0062] For example, such as Figure 4 As shown, a rotating groove 121 is also provided on the base plate 12, and a handle 134 is provided inside the rotating groove 121. The first drive rod 133 enters the rotating groove 121 and connects with the handle 134. Rotating the handle 134 can drive the first drive rod 133 to rotate, thereby causing the bottom gear disk 131 to rotate and adjusting the arc plate 11. It is worth noting that the handle 134 is located inside the rotating groove 121, and the height of the handle 134 is less than the depth of the rotating groove 121 to avoid the handle 134 affecting the flatness of the base plate 12.

[0063] Preferred, such as Figure 6 As shown, the irregular workpiece fixing device also includes a placement pad 6, which is arranged around the positioning block 14 and connected to the base plate 12 for placing the workpiece 7.

[0064] Furthermore, such as Figure 5 As shown, the irregular workpiece fixing device also includes a pressure plate assembly 4, which is disposed on the positioning block 14.

[0065] The pressure plate assembly 4 includes a fixing rod 41, a fixing bolt 42, and a pressure plate 43. The pressure plate 43 is provided with a fixing groove. One end of the fixing rod 41 is connected to the positioning block 14, and the other end passes through the fixing groove and is threaded to the fixing bolt 42. Tightening the fixing bolt 42 can fix the position of the pressure plate 43.

[0066] In step S2, specifically, the clamping plate 43 is pressed tightly against the open end frame 73, and the fixing bolt 42 is rotated to press the clamping plate 43 against the open end frame 73.

[0067] Furthermore, step S3 specifically includes:

[0068] S31: Adjust top plate 2;

[0069] S32: Fix the connection between the top plate 2 and the workpiece 7.

[0070] Specifically, such as Figure 7 As shown, the top plate 2 is provided with a connecting hole 21, an arc-shaped positioning block 22, and a second adjusting member 23. The connecting hole 21 is provided on the top plate 2 and is used to connect the tension connecting member 3. Multiple arc-shaped positioning blocks 22 are provided, and multiple arc-shaped positioning blocks 22 form a circular structure. The arc-shaped positioning blocks 22 are connected to the second adjusting member 23, and the position of the arc-shaped positioning blocks 22 can be adjusted through the second adjusting member 23.

[0071] In step S31, specifically, the top plate 2 is placed on the top frame 72 of the workpiece 7, the tension connector 3 is inserted into the connection hole 21, and the second adjusting member 23 is adjusted so that the arc-shaped positioning block 22 is tightly attached to the inner wall of the top frame 72.

[0072] Furthermore, the second adjusting member 23 includes a top gear disk 231, a second driving gear 232, a second driving rod 233, and a rocker arm 234. The top gear disk 231 and the second driving gear 232 are connected to the top plate 2 through bearing seats. The second driving gear 232 meshes with the top gear disk 231. The second driving rod 233 is connected to the second driving gear 232. Rotating the second driving rod 233 can cause the second driving gear 232 to rotate. The second driving rod 233 passes through the top plate 2 and is connected to the rocker arm 234. Rotating the rocker arm 234 can drive the second driving rod 233 to rotate, thereby causing the second driving gear 232 to drive the top gear disk 231 to rotate. The top gear disk 231 is provided with positioning arc grooves 2311, the number of which is the same as that of the arc-shaped positioning blocks 22. The arc-shaped positioning blocks 22 are provided with connecting rods 221 and moving ends 222. The arc-shaped positioning blocks 22 are connected to the moving ends 222 through the connecting rods 221. The moving ends 222 are located in the positioning arc grooves 2311. When the top gear disk 231 rotates, the moving ends 222 move along the positioning arc grooves 2311, causing the arc-shaped positioning blocks 22 to move with the moving ends 222, thereby increasing or decreasing the size of the circular structure formed by the arc-shaped positioning blocks 22, so that the arc-shaped positioning blocks 22 are tightly attached to the inner wall of the top frame 72.

[0073] Furthermore, such as Figure 2 As shown, the tension connector 3 includes a tension rod 31 and a tension nut 32. One end of the tension rod 31 is connected to the positioning block 14, and the other end enters the connection hole 21 and is threadedly connected to the tension nut 32.

[0074] In step S32, specifically, the tension nut 32 is connected to the tension rod 31, so that the top plate 2 presses against the top frame 72, thereby fixing the position of the workpiece 7 through the top plate 2 and the base 1.

[0075] In step S4, specifically, the stability of the workpiece 7 is checked, and the tension nut 32 is adjusted to make the workpiece 7 securely fixed.

[0076] For example, such as Figures 8-9 As shown, the irregular workpiece fixing device also includes a fixing detection component 5. The fixing detection component 5 includes a pressing ball 51, a column 52, a movable shell 53, a bidirectional pressure plate 54, a support frame 55, and a support spring 56. The movable shell 53 is disposed inside the base plate 12, and the top surface of the movable shell 53 is coplanar with the base plate 12. The pressing ball 51, column 52, bidirectional pressure plate 54, support frame 55, and support spring 56 are disposed inside the movable shell 53. The support frame 55 is fixedly connected to the movable shell 53, and the bidirectional pressure plate 54 is fixedly connected to the movable shell 53. The movable shell 53 is hinged. One end of the bidirectional pressure plate 54 is connected to the pressing ball 51, and the other end is connected to the column 52. The movable shell 53 is provided with a spherical hole and a cylindrical hole. The spherical hole cooperates with the pressing ball 51, allowing the pressing ball 51 to protrude from the movable shell 53. The cylindrical hole cooperates with the column 52, allowing the column 52 to protrude from the movable shell 53. A support spring 56 is provided at the end of the bidirectional pressure plate 54 connected to the pressing ball 51, and the support spring 56 causes the pressing ball 51 to protrude from the spherical hole. The pressing ball 51 is located on the side closer to the arc plate 11, and the column 52 is located on the side away from the arc plate 11.

[0077] Preferably, a sliding groove 122 is provided on the base plate 12, and the movable shell 53 is disposed in the sliding groove 122 and can move along the sliding groove 122, so that the fixed detection component 5 can be adjusted according to the position of the arc plate 11.

[0078] Preferably, multiple fixed detection components 5 are provided to increase the accuracy of checking the stability of the workpiece 7.

[0079] When the workpiece 7 is fixed, when the inner wall of the bottom frame 71 is in close contact with the arc plate 11, the bottom frame 71 presses the pressing ball 51, causing the pressing ball 51 to compress the support spring 56 and enter the spherical hole, causing one end of the column 52 of the bidirectional pressure plate 54 to rise, causing the column 52 to protrude from the column hole, indicating to the technician that the workpiece 7 has been firmly fixed.

[0080] When testing the stability of the workpiece 7, tilt the workpiece 7. If the workpiece 7 is not securely fixed, it will shift under the tilting action, causing a gap between the bottom frame 71 and the base plate 12. The pressing ball 51 at the gap will protrude out of the spherical hole under the action of the supporting spring 56, allowing the column 52 to enter the columnar hole, thus indicating to the technician that the workpiece 7 needs to be further fixed.

[0081] In step S5, specifically, the irregular workpiece fixing device that fixes the workpiece 7 is placed on the processing platform of the processing machine, and the workpiece 7 is processed by the processing machine.

[0082] Furthermore, step S6 specifically includes:

[0083] S61: Remove top plate 2;

[0084] S62: Release the fixation on the open end frame 73;

[0085] S63: Separate workpiece 7.

[0086] In step S61, specifically, the tension nut 32 is rotated to separate the tension nut 32 from the tension rod 31, the rocker arm is rotated to move the arc-shaped positioning block 22 away from the top frame 72, and the top plate 2 is removed by the hoisting device.

[0087] In step S62, specifically, the fixing bolt 42 is loosened, and the clamping plate 43 is moved away from the workpiece 7, so that the fixing groove moves along the fixing rod 41, thereby releasing the clamping plate 43 from fixing the open end frame 73.

[0088] In step S63, specifically, the position of the arc plate 11 is adjusted by the handle 134 so that the arc plate 11 is away from the bottom frame 71, and then the workpiece 7 is hoisted by the hoisting device so that the workpiece 7 is separated from the irregular workpiece fixing device.

[0089] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
