Abstract

This invention provides a flexible machining equipment for precision parts, relating to the field of machining device technology. A worktable is installed inside the housing, and a clamping device for holding tightly fitted parts is installed at the upper end of the worktable. The operator first installs the clamping device in a set position according to the shape and size of the workpiece to be processed. Then, the drive device starts working, driving the rotating shaft to rotate. A threaded cylinder mounted on the outer wall of the rotating shaft is hinged to a connecting rod, causing the threaded cylinder to move away from the baffle. The threaded cylinder drives the connecting rod to move, which in turn drives the L-shaped clamping rod to move. The L-shaped clamping rod then drives the clamping blocks to move, bringing the two clamping blocks closer together and thus stabilizing the workpiece. Because the clamping device is detachable and movable, it can accommodate workpieces of different sizes. Furthermore, since the clamping device can be installed on various surfaces, this clamping device can hold not only flat workpieces but also round workpieces.

Description

Technical Field

[0001] This invention relates to the field of processing equipment technology, and more specifically, to a flexible processing equipment for precision parts. Background Technology

[0002] Flexible manufacturing has two aspects. First, it refers to the system's ability to adapt to changes in the external environment, which can be measured by the degree to which the system meets the requirements of new products. Second, it refers to the system's ability to adapt to internal changes, which can be measured by the ratio of the system's expected productivity under disruptive conditions, such as machine malfunctions, to the expected productivity under undisrupted conditions. "Flexibility" is relative to "rigidity," and traditional "rigid" automated production lines mainly achieve mass production of a single product.

[0003] The patent "CN202022988054.7" proposes to set up a first clamping mechanism and a second clamping mechanism. During operation, the workpiece can be clamped by simply rotating the eccentric wheel with the handle. When the thickness of the workpiece changes, the clamping angle of the clamping block can be expanded or reduced by simply rotating the shaft with the eccentric wheel to raise or lower the shaft. When clamping workpieces of the same thickness, the appropriate height of the eccentric wheel can be set in advance, making the operation more convenient, faster, and improving the overall workpiece processing efficiency.

[0004] The clamping device in this patent cannot achieve a good clamping performance when clamping irregularly shaped parts with different heights at the edges, when clamping parts with protrusions in the middle, or when clamping parts with inclined edges, thus reducing the practicality of the device.

[0005] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a flexible processing equipment for precision parts, in order to achieve a more practical value. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a precision parts flexible processing equipment to solve the problem of not being able to effectively clamp some special irregularly shaped processing parts.

[0007] The purpose and effectiveness of this invention's flexible machining equipment for precision parts are achieved through the following specific technical means:

[0008] A precision parts flexible processing equipment includes a housing of the processing equipment, a worktable installed inside the housing, a clamping device for clamping tightly fitted parts installed at the upper end of the worktable, a plurality of positioning components installed at the lower end of the clamping device, and a driving device connected to one side of the clamping device.

[0009] The clamping device includes a mounting base, on which a vertical plate is fixedly mounted. A rotating body is rotatably connected to the upper end of the vertical plate. A connecting frame is fixedly mounted at one end of the rotating body. L-shaped clamping rods are hinged to the upper and lower ends of the connecting frame, and clamping blocks are hinged to the ends of the L-shaped clamping rods. A connecting rod is hinged to the middle position of the L-shaped clamping rods. The two connecting rods are hinged together to the outer wall of the threaded cylinder. A rotating shaft is rotatably connected to the middle position of the connecting frame. The rotating shaft has a threaded section on its outer wall outside the connecting frame for use with the threaded cylinder. A baffle is rotatably connected to the end of the rotating shaft.

[0010] Furthermore, the outer wall of the workbench is provided with a feeding hole, and the edge of the feeding hole is provided with a limiting hole for use with the mounting base.

[0011] Furthermore, the driving device includes a gear rotatably connected to the lower end of the workbench by a rotating rod and a rotating rod rotatably mounted on the outer wall of the vertical plate. The gear is fixedly connected to the rotating rod. A pulley is fixedly mounted at the middle position of the rotating rod. Each pulley is connected by a belt, which is driven by a motor. The lower end of the rotating rod has a toothed groove for engaging the gear. A connecting assembly is installed at the upper end of the rotating rod. A worm gear is installed at the upper end of the connecting assembly. A worm wheel for the accessory worm gear is fixedly mounted at one end of the rotating shaft. The worm wheel is wider than the outer diameter of the worm gear.

[0012] Furthermore, the positioning component includes a movable rod that is slidably connected to the mounting base. A limit plate is fixedly provided at the lower end of the movable rod, and a disc is hinged to the upper end of the movable rod. The movable rod is hinged to the edge of the disc, and a fixed shaft is fixedly provided on the outer wall of the disc.

[0013] Furthermore, the connecting assembly includes a connecting cylinder fixedly disposed at the lower end of the worm gear, with extrusion blocks evenly distributed at the lower end of the connecting cylinder. The cross-section of the extrusion blocks is trapezoidal, and the outer wall of the connecting cylinder is threaded with an extrusion cylinder. The upper end of the rotating rod is located in the middle of the extrusion blocks, and a resistance pad is disposed between the extrusion blocks and the rotating rod.

[0014] Furthermore, the clamping block includes a pressing plate hinged to the lower end of the L-shaped clamping rod, and multiple connecting blocks are slidably arranged on both sides of the pressing plate, with each connecting block slidably connected in pairs. Anti-slip pads are provided on the outer walls of the pressing plate and the connecting blocks.

[0015] Furthermore, a fixing rod is fixedly installed at each end of the baffle, and the other end of the fixing rod is fixedly connected to the connecting frame.

[0016] Furthermore, the extrusion blocks are circumferentially distributed, and the gaps between the extrusion blocks are equal.

[0017] Furthermore, a gear is provided at the position of each of the feeding holes.

[0018] Furthermore, the outer wall of the upright plate is threaded with a limiting bolt for use with the rotating body.

[0019] Furthermore, the rotating rod is a telescopic rod, including an outer cylinder and a telescopic rod, the telescopic rod being slidably connected to the outer cylinder, the interior of the upright plate being hollow, a fixed plate being slidably disposed inside the upright plate, a locking bolt being disposed between the upright plate and the fixed plate, and the fixed plate being fixedly connected to the mounting base.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The operator first installs the clamping device in the set position according to the shape and size of the workpiece to be processed. Then the drive device starts to work, driving the rotating shaft to rotate. The threaded cylinder set on the outer wall of the rotating shaft is hinged to the connecting rod. Therefore, the threaded cylinder will move away from the baffle. The threaded cylinder will drive the connecting rod to move, the connecting rod will drive the L-shaped clamping rod to move, and the L-shaped clamping rod will drive the clamping block to move, so that the two clamping blocks are brought closer to each other, thereby clamping the workpiece stably. By detaching and moving the clamping device, it can adapt to workpieces of different sizes and specifications. At the same time, since the clamping device can be installed, this clamping device can not only clamp flat workpieces, but also round workpieces.

[0022] 2. By rotating the extrusion cylinder, the lower end of the extrusion cylinder is brought into contact with the extrusion block and squeezed. The extrusion block then squeezes the rotating rod, increasing the friction between the extrusion block and the rotating rod. Conversely, decreasing the friction between the extrusion block and the rotating rod allows the clamping device to adjust the clamping force when different clamping positions require different thicknesses. Once the clamping device is fully tightened, the rotating shaft cannot continue to rotate, and the worm gear also cannot rotate. At this point, the extrusion block and the rotating rod will rotate. By changing the friction between the extrusion block and the rotating rod, the clamping force of the clamping device can be adjusted to accommodate different materials and avoid excessive clamping force that could damage the workpiece.

[0023] 3. Since both the rotating rod and the upright plate of this device can move up and down, the positions of the rotating rod and the upright plate can be adjusted according to the different heights of the workpiece, thus adapting to workpieces with stepped edges.

[0024] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0038] Example:

[0039] As attached Figure 1 To be continued Figure 3 As shown:

[0040] This invention provides a precision parts flexible processing equipment, including a housing 1, a worktable 3 installed inside the housing 1, a clamping device 2 for clamping tightly fitted parts installed on the upper end of the worktable 3, multiple positioning components 4 installed on the lower end of the clamping device 2, a driving device 5 connected to one side of the clamping device 2, the clamping device 2 including a mounting base 201, a vertical plate 202 fixedly mounted on the upper end of the mounting base 201, a rotating body 203 rotatably connected to the upper end of the vertical plate 202, and a connecting frame fixedly provided at one end of the rotating body 203. 204. L-shaped clamping rods 205 are hinged to the upper and lower ends of the connecting frame 204. Clamping blocks 210 are hinged to the ends of the L-shaped clamping rods 205. A connecting rod 206 is hinged to the middle of the L-shaped clamping rods 205. Both connecting rods 206 are hinged to the outer wall of the threaded cylinder. A rotating shaft 207 is rotatably connected to the middle of the connecting frame 204. The rotating shaft 207 has a threaded section on its outer wall outside the connecting frame 204 for use with the threaded cylinder. A baffle 208 is rotatably connected to the end of the rotating shaft 207. Worktable 3. The outer wall of the baffle 208 has a feeding hole 301, and the edge of the feeding hole 301 has a limiting hole for use with the mounting base 201. Fixed rods 209 are fixedly installed at both ends of the baffle 208, and the other end of the fixed rods 209 is fixedly connected to the connecting frame 204. In practical applications, the operator first installs the clamping device 2 in the set position according to the shape and size of the workpiece to be processed. Then, the drive device 5 starts working, driving the rotating shaft 207 to rotate. The threaded cylinder set on the outer wall of the rotating shaft 207 is hinged to the connecting rod 204. 06. Therefore, the threaded cylinder will move away from the baffle 208, and the threaded cylinder will drive the connecting rod 206 to move. The connecting rod 206 will drive the L-shaped clamping rod 205 to move, and the L-shaped clamping rod 205 will drive the clamping block 210 to move, so that the two clamping blocks 210 move closer to each other, thereby clamping the workpiece stably. By using the detachable and movable clamping device 2, it can adapt to workpieces of different sizes and specifications. At the same time, since the clamping device 2 can be installed, this clamping device can not only clamp flat workpieces, but also round workpieces.

[0041] As attached Figure 2 and attached Figure 5 As shown: The driving device 5 includes a gear 501 rotatably connected to the lower end of the worktable 3 by a rotating rod and a rotating rod 502 rotatably mounted on the outer wall of the vertical plate 202. The gear 501 is fixedly connected to the rotating rod. A pulley is fixedly mounted in the middle of the rotating rod. Each pulley is connected by a belt, which is driven by a motor. The lower end of the rotating rod 502 has a tooth groove that matches the gear 501. A connecting component 503 is installed at the upper end of the rotating rod 502. A worm gear 504 is installed at the upper end of the connecting component 503. A worm wheel 505 for the accessory worm gear 504 is fixedly mounted at one end of the rotating shaft 207. The worm wheel 505 is wider than the outer diameter of the worm gear 504. A gear 501 is provided at the position of each feeding hole 301. In practical applications, since a gear 501 is provided at the position of each feeding hole 301, the clamping device 2 can be installed at any feeding hole 301. The gear 501 can drive the rotating rod 502 to rotate.

[0042] As attached Figure 8 As shown: The positioning component 4 includes a movable rod 403 that is slidably connected to the mounting base 201. A limit plate 404 is fixedly installed at the lower end of the movable rod 403. An anti-slip pad is attached to the upper end of the limit plate 404. A disc 401 is hinged to the upper end of the movable rod 403. The movable rod 403 is hinged to the edge of the disc 401. A fixed shaft 402 is fixedly installed on the outer wall of the disc 401. In practical applications, the operator rotates the disc 401 through the fixed shaft 402 to lock the drive device 5 at the upper end of the worktable, thereby facilitating the operator to disassemble and install the clamping device 2.

[0043] As attached Figure 6 and attached Figure 7As shown: The connecting assembly 503 includes a connecting cylinder 5032 fixedly disposed at the lower end of the worm gear 504. Extrusion blocks 5033 are evenly distributed at the lower end of the connecting cylinder 5032. An extrusion cylinder 5031 is threadedly connected to the outer wall of the connecting cylinder 5032. The upper end of the rotating rod 502 is located in the middle of the extrusion blocks 5033. The cross-section of the extrusion blocks 5033 is trapezoidal. A resistance pad is provided between the extrusion blocks 5033 and the rotating rod 502. In practical applications, by rotating the extrusion cylinder 5031, the lower end of the extrusion cylinder 5031 is brought into contact with the extrusion blocks 5033, thus compressing them. Consequently, the extrusion blocks 5033 compress the rotating rod 502. This increases the friction between the extrusion block 5033 and the rotating rod 502, and conversely decreases the friction between the extrusion block 5033 and the rotating rod 502. Therefore, when the clamping device 2 needs to clamp different thicknesses at different positions, after the clamping device 2 is fully clamped, the rotating shaft 207 cannot continue to rotate, and the worm gear 504 also cannot rotate. At this time, the extrusion block 5033 and the rotating rod 502 will rotate. Thus, by changing the friction between the extrusion block 5033 and the rotating rod 502, the clamping force of the clamping device 2 can be adjusted, thereby changing the clamping force to cope with different materials and avoiding excessive clamping force that could damage the workpiece.

[0044] As attached Figure 4 As shown: The clamping block 210 includes a pressing plate 2101 hinged to the lower end of the L-shaped clamping rod 205. Multiple connecting blocks 2102 are slidably arranged on both sides of the pressing plate 2101. Each connecting block 2102 is slidably connected in pairs. Anti-slip pads are provided on the outer walls of the pressing plate 2101 and the connecting blocks 2102. The pressing blocks 5033 are circumferentially distributed and the gaps between the pressing blocks 5033 are equal. In practical applications, when the edge of the workpiece is arc-shaped or irregular, the edge of the workpiece is tightened by adjusting the position of the pressing blocks 5033, thereby accommodating more workpieces of different shapes and specifications.

[0045] As attached Figure 2 As shown: The outer wall of the upright plate 202 is threaded with a limiting bolt that is used to cooperate with the rotating body 203. In practical applications, the rotating body 203 can move left and right, and should also rotate to adapt to workpieces with inclined edges. Since the worm wheel 505 is wider than the outer diameter of the worm 504, it will not be affected during left and right movement.

[0046] As attached Figure 2As shown: The rotating rod 502 is a telescopic rod, including an outer cylinder and a telescopic rod. The telescopic rod is slidably connected to the outer cylinder. The interior of the upright plate 202 is hollow, and a fixed plate is slidably installed inside the upright plate 202. A locking bolt is provided between the upright plate 202 and the fixed plate. The fixed plate is fixedly connected to the mounting base 201. In practical applications, since both the rotating rod 502 and the upright plate 202 can move up and down, their positions can be adjusted according to the different heights of the workpiece, thus adapting to workpieces with stepped edges.

[0047] The specific usage and function of this embodiment are as follows:

[0048] In use, the operator first installs the clamping device 2 in the set position according to the shape and size of the workpiece to be processed. Then, the drive device 5 starts to work, driving the rotating shaft 207 to rotate. The threaded cylinder set on the outer wall of the rotating shaft 207 is hinged to the connecting rod 206. Therefore, the threaded cylinder will move away from the baffle 208. The threaded cylinder will drive the connecting rod 206 to move. The connecting rod 206 will drive the L-shaped clamping rod 205 to move. The L-shaped clamping rod 205 will drive the clamping block 210 to move, so that the two clamping blocks 210 are brought closer to each other, thereby clamping the workpiece stably. By detachably moving the clamping device 2, it can adapt to workpieces of different sizes and specifications. At the same time, since the clamping device 2 can be installed, this clamping device can not only clamp flat workpieces, but also round workpieces.

[0049] The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and to design various embodiments with various modifications suitable for a particular purpose.
