The loading frame 1 comprises a base 11, four supporting columns 12 and a loading plate 13. In the embodiment, the base 11 is square, and the four supporting pillars 12 are respectively vertically disposed at four corners of the surface of the base 11. The carrier plate 13 is also square and is connected to the top ends of the support posts 12 to form an elevated space 14 horizontally spaced from the base 11. The carrier plate 13 has an upper surface 131 and a lower surface 132 on opposite sides, four side surfaces 133 connecting the upper surface 131 and the lower surface 132, two bottom grooves 134 recessed from the lower surface 132 and respectively penetrating through the two adjacent side surfaces 133, and four limiting grooves 135 penetrating through the upper surface 131 and the lower surface 132, wherein the two limiting grooves 135 form a set, and the two sets of limiting grooves 135 are respectively disposed corresponding to the two bottom grooves 134. The elevated space 14 is located below the lower surface 132 of the carrier plate 13. Each bottom groove 134 is recessed from the junction of the side surface 133 and the lower surface 132.

Referring to fig. 4 and 5, the positioning stage 2 is disposed at the center of the upper surface 131 of the supporting plate 13 and protrudes from the upper surface 131 of the supporting plate 13, and includes a base 21 and a plurality of positioning blocks 22. The base 21 is also substantially rectangular in appearance and has four corners in the shape of an arc to match the shape of the workpiece 9. The base 21 has a top surface 211, two short side surfaces 212 extending downward from two opposite short sides of the top surface 211, and two long side surfaces 213 extending downward from two opposite long sides of the top surface 211. The top surface 211 has a contact surface 211a protruding upwards along the periphery of the seat 21 for the corresponding placement of the workpiece 9. Two grooves 214 connected to the limiting groove 135 are recessed in one of the short side surfaces 212 and one of the long side surfaces 213 of the positioning table 2.

The positioning block 22 is disposed on the top surface 211 and protrudes from the top surface 211, and is disposed along the contact surface 211 a. In detail, in the present embodiment, the positioning block 22 is divided into three primary positioning blocks 22a and four precise positioning blocks 22 b. The primary positioning blocks 22a are cylindrical and correspondingly disposed on two adjacent sides of the top surface 211, one of the primary positioning blocks 22a is disposed on the short side of the top surface 211, and the other two primary positioning blocks 22a are disposed on the long side of the top surface 211. The workpiece 9 may be placed in alignment along the preliminary positioning block 22a on the contact surface portion 211a of the positioning table 2. The precisely positioning blocks 22b are square columns and are disposed on two adjacent sides of the top surface 211, so as to be matched with the inner shaping mechanism 3 and distributed around the positioning table 2, and can press the inner peripheral surface 911 of the workpiece 9 together.

Referring to fig. 1, 6 to 8, the inner shaping mechanisms 3 are disposed on the loading plate 13 of the loading frame 1 and respectively corresponding to two adjacent sides of the positioning table 2, such that the two inner shaping mechanisms 3 are respectively located at the long side and the short side of the positioning table 2, so as to be suitable for pressing the long side and the short side of the inner circumferential surface 911 of the workpiece 9. In the present embodiment, each inner shaping mechanism 3 is disposed corresponding to one bottom groove 134 and two limiting grooves 135 of the same set, and the two limiting grooves 135 of the same set are spaced from each other and extend perpendicularly to the side surface of the positioning table 2 to form a long shape and are connected to the groove 214 of the positioning table 2.

Referring to fig. 3, 4, 6 and 7, since the structure and operation of each inner shaping mechanism 3 are the same, only one inner shaping mechanism 3 is described as an example. The inner shaping mechanism 3 includes a fixed block 31, a sliding block 32, an actuating block 33, a first cylinder 35, a piston set 36, two inner shaping air valves 37, a sensor (not shown) and a reset module 34. The fixing block 31 is connected to the lower surface 132 of the supporting plate 13 and located below the corresponding bottom slot 134, and defines a pair of opposite guide slots 311. The sliding block 32 is slidably disposed in the guide slot 311, accommodated in the bottom slot 134, and can slide in a horizontal direction relative to the fixed block 31. The sliding block 32 has a sliding body 321 and two pushing members 322. In addition, referring to fig. 8, the sliding body 321 is disposed in the bottom groove 134 of the supporting plate 13 and has a sliding portion 321a and two connecting portions 321b which are spaced apart from each other and extend from one side of the sliding portion 321a to the center of the supporting plate 13 and are bent upward to extend into the two limiting grooves 135 of the same group. The sliding portion 321a has an upright abutting surface 321c and an inclined guide surface 321d connected to the upright abutting surface 321 c. The ends of the connecting portions 321b are respectively connected to the two pushing elements 322, so that the pushing elements 322 pass through the two limiting grooves 135 of the same set and pass through the top surface 211 of the positioning table 2 along the groove 214 of the positioning table 2. The pushing element 322 is driven by the sliding body 321 to press the inner peripheral surface 911 of the workpiece 9. The push-against piece 322 is movable in a first initial position (see fig. 7) closer to the center of the positioning table 2 and a first final position (see fig. 8) closer to the periphery of the positioning table 2.

The actuating block 33 is vertically slidably disposed on the fixed block 31 to drive the sliding block 32 to slide horizontally. In detail, the actuating block 33 is connected to the piston set 36 and can be moved up and down by the piston set 36. The actuating block 33 has a body portion 331 and a pushing portion 332 projecting from the body portion 331. The pushing portion 332 has a slope 332 a. When the pushing element 322 of the sliding block 32 is in the first initial position, the inclined surface 332a of the actuating block 33 is connected to the inclined guiding surface 321 d. When the actuator block 33 is pulled down by the piston assembly 36, the pushing portion 332 of the actuator block 33 slides downward from the contact position with the inclined guide surface 321d, and presses the inclined guide surface 321d of the sliding portion 321a, and the inclined surface 332a of the pushing portion 332 and the inclined guide surface 321d of the sliding portion 321a slide relative to each other, so that the slide block 32 is driven to horizontally slide in a direction away from the positioning table 2, the urging member 322 of the slide block 32 moves outward from the first initial position, and presses the inner circumferential surface 911 of the workpiece 9, and the precision positioning block 22b also presses the inner circumferential surface 911 of the workpiece 9 until the pushing portion 332 of the actuator block 33 and the upright abutment surface 321c contact each other, and the urging member 322 of the slide block 32 reaches the first final position. The inclined surface 332a of the pushing part 332 and the inclined guide surface 321d of the sliding part 321a slide relatively, so that a large movement amount of the first piston 361 in the vertical direction is converted into a small movement amount of the slide block 32 in the horizontal direction, and the inner shaping mechanism 3 can precisely shape the workpiece 9.

The reset module 34 is used for providing an elastic restoring force for the sliding block 32 to move towards the positioning table 2, and has a reset block 341 connected to the sliding block 32 and a reset spring 342 with two ends correspondingly abutting against the reset block 341 and the fixed block 31. When the pushing portion 332 of the actuating block 33 is lifted by the first piston 361 and slides upward from the joint with the upright abutting surface 321c to the position of the adjacent inclined guiding surface 321d, the return spring 342 provides an elastic restoring force to the sliding block 32, so that the sliding block 32 slides toward the positioning table 2, the inclined guiding surface 321d abuts against the pushing portion 332 of the actuating block 33, and the pushing member 322 returns to the first initial position.

In the present embodiment, the first cylinder 35 is connected below the fixed block 31 and defines a first air chamber 351 closer to the fixed block 31 and a second air chamber 352 farther from the fixed block 31. The piston group 36 is provided in the first cylinder 35, and includes a first piston 361 provided in the first air chamber 351 and connected to the actuator block 33, and a second piston 362 provided in the second air chamber 352 and connected to the first piston 361. The two inner shaping air valves 37 are connected to the first cylinder 35 for delivering air into and out of the second air chamber 352 to drive the second piston 362 to move up and down, and drive the first piston 361 to move up and down, thereby driving the actuating block 33 to move in the fixed block 31 and the sliding block 32. The sensor is used for detecting the top dead center position and the bottom dead center position of the piston set 36. The piston group 36 has the risk of dead card in the use, and when the inductor detected that piston group 36 did not put in place, the inductor can report to the police, avoids the risk of hitting the machine.

Referring to fig. 3 and 4, the outer shaping mechanism 4 is disposed on the upper surface 131 of the supporting plate 13 and distributed corresponding to the periphery of the positioning table 2. In the present embodiment, each long side surface 213 of the positioning table 2 corresponds to two side-by-side outer shaping mechanisms 4, and each short side surface 212 of the positioning table 2 corresponds to one outer shaping mechanism 4, but the present embodiment is not limited thereto. Each outer shaping mechanism 4 is for pressing an outer peripheral surface 912 of the workpiece 9, and has a fixed plate 41, a second cylinder 42, and a push rod 43. The fixing plate 41 is disposed on the upper surface 131 of the carrier plate 13 so that the height of the push rod 43 is aligned with the top side of the positioning table 2. The second cylinder 42 is provided on the fixed plate 41 to drive the push rod 43 to press the outer peripheral surface 912 of the workpiece 9, and may be replaced with a hydraulic cylinder or another suitable cylinder capable of generating a propulsive force according to the actual situation. The push rod 43 has a rod body 431 and a pushing part 432 located at the end of the rod body 431. The pushing portion 432 is made of a soft material such as rubber. The push rod 43 is controllably moved from a second initial position farther from the outer periphery of the positioning table 2 to a second end position closer to the outer periphery of the positioning table 2, and presses the outer peripheral surface 912 and the inner peripheral surface 911 of the workpiece 9 in cooperation with the inner shaping mechanism 3. When the push rod 43 moves to the second end position and the pushing member 322 of the slide block 32 moves to the first end position, the shape of the workpiece 9 is shaped to meet the requirement. Each outer shaping mechanism 4 further has a third piston (not shown) disposed in the second cylinder 42 and connected to the rod portion 431 of the push rod 43, two outer shaping valves 44 connected to the second cylinder 42 for delivering gas into and out of the second cylinder 42 to drive the third piston, and a sensor (not shown) disposed in the second cylinder 42. The aforementioned sensor has the same function as the sensor mentioned in the inner shaping mechanism 3, and therefore, the description thereof is omitted.

The shaping speed of the inner shaping mechanism 3 and the outer shaping mechanism 4 can be controlled by the inner shaping mechanism 3 and the outer shaping mechanism 4 through a speed regulating valve. For example, since the deformation amount of the short side of the workpiece 9 is small and the deformation amount of the long side is large, the speed regulating valve can decrease the shaping speed of the inner shaping mechanism 3 and the outer shaping mechanism 4 corresponding to the short side of the workpiece 9 and increase the shaping speed of the inner shaping mechanism 3 and the outer shaping mechanism 4 corresponding to the long side of the workpiece 9, so that the long side and the short side of the workpiece 9 can be shaped to a desired shape, and the two-degree deformation in the shaping process is avoided. In the present embodiment, the inner shaping mechanisms 3 and the outer shaping mechanisms 4 are used to shape the short sides of the workpiece 9 first and then shape the long sides of the workpiece 9, but the present invention is not limited thereto.

The pressing mechanism 5 is disposed on the carriage 1 and is used for pressing the pressing plate 6 to fix the workpiece 9 with the finished length and width to the positioning table 2. In detail, when the length and the width of the workpiece 9 are shaped, the pressing plate 6 can be placed on the workpiece 9 and tightly fit with the inner circumferential surface 911 of the workpiece 9, and then the pressing mechanism 5 presses the pressing plate 6, so that the positioning table 2 and the pressing plate 6 jointly clamp the workpiece 9, and the workpiece 9 is fixed on the positioning table 2 for the subsequent processing. The platen 6 can also shape the height of the workpiece 9 by the pressing mechanism 5.

Referring to fig. 3, 4 and 9, the pressing mechanism 5 includes a third cylinder 51, a connecting member 52, a bridge plate 53 and two pressing members 54. The third cylinder 51 is disposed on the base 11 of the carriage 1 and located in the elevated space 14. In the present embodiment, the third cylinder 51 is a double-force cylinder, but may be replaced with a rotary cylinder, a normal standard cylinder, a hydraulic cylinder, or another cylinder depending on the actual situation. The link 52 is connected to the third cylinder 51 and can be driven by the third cylinder 51 to move up and down. The bridge plate 53 is pivotally connected to the connecting member 52. The pressing members 54 are pivotally connected to opposite ends of the bridge plate 53 and penetrate through the bearing plate 13 and the top surface 211 of the positioning table 2, and each pressing member 54 has a shaft portion 541 pivotally connected to the bridge plate 53 and a head portion 542 connected to the shaft portion 541. The bridge plate 53 is used to balance the high and low positions of the rod heads 542 of the two pressing members 54. When the pressing plate 6 is placed on the workpiece 9, the pressing plate 6 may not be in a horizontal state due to slight deformation of the workpiece 99 in height, so that one of the rod heads 542 of the two pressing members 54 contacts the pressing plate 6 first when being pulled down, and at the same time, the bridge plate 53 can pivot relative to the connecting member 52 to adjust the rod heads 542 of the two pressing members 54 to be parallel to the pressing plate 6 in real time.

The pressing plate 6 includes two through holes 61 and two limiting holes 62 respectively connected to the through holes 61. The diameter of each through hole 61 is larger than that of each stopper hole 62, and the diameter of each stopper hole 62 corresponds to the outer diameter of the shaft body 541. The bore diameter of each bore 61 corresponds to the outer diameter of the stem head 542. Referring to fig. 10 to 12, in the present embodiment, in the process of placing the pressing plate 6 on the workpiece 9, the through hole 61 of the pressing plate 6 is firstly sleeved on the rod head portion 542 of the pressing member 54, and then the pressing plate 6 is moved along the first direction D1 as shown in fig. 11, so that the limiting hole 62 corresponds to the rod body portion 541, and then the pressing plate 6 is abutted to the inner circumferential surface 911 of the workpiece 9. Finally, the third cylinder 51 is activated to drive the connecting member 52 (see fig. 9) to pull the bridge plate 53 (see fig. 9) and the pressing member 54, so that the rod head 542 of the pressing member 54 presses against the pressing plate 6.

The shaping process of the processing fixture 100 of the embodiment is as follows: the workpiece 9 is placed in alignment along the preliminary positioning block 22a on the contact surface portion 211a of the positioning table 2; starting the inner and outer shaping mechanisms 3 and 4, driving the piston group 36 to move downwards through the first cylinder 35 of the inner shaping mechanism 3, linking the actuating block 33 to move vertically in the fixed block 31, the actuating block 33 simultaneously pressing the inclined guide surface 321d of the sliding part 321a of the sliding block 32 to make the sliding block 32 generate relative sliding, sliding in the guide groove 311 of the fixed block 31 in the direction away from the positioning table 2, and the pushing part 322 simultaneously moving from the first initial position to the first final position in the limit groove 135; in addition, the second cylinder 42 of the outer shaping mechanism 4 drives the push rod 43 to move from the second initial position to the second end position, so that the push rod 43 and the pushing part 322 are matched to respectively push against the outer circumferential surface 912 and the inner circumferential surface 911 of the workpiece 9, and the workpiece 9 is shaped in length and width to meet the expectation; sleeving the pressing plate 6 on the pressing part 54 of the pressing mechanism 5 and clamping the pressing plate on the inner circumferential surface 911 of the workpiece 9; starting the pressing mechanism 5 to enable the pressing piece 54 to move downwards to press against the pressing plate 6, further enabling the workpiece 9 to be shaped in height to meet the expectation, and fixing the workpiece 9 on the positioning table 2; the ram 43 is optionally retracted to a second home position to provide sufficient space for an external machining tool (not shown) to machine the outer peripheral surface 912 of the workpiece 9.
