Description

Technical Field

[0001] This invention relates to the field of valve body processing technology, and in particular to a production line for processing manual valve bodies. Background Technology

[0002] The valve body is the core component of a manual valve, mainly used to form the internal flow channel, installation structure, and sealing system of the valve. With the advancement of industrial automation, the market demand for manual valves is increasing, and the product models are diverse, requiring production lines to have efficient and flexible production capabilities to meet the processing needs of valve bodies of different specifications and materials (such as stainless steel, copper alloy, and engineering plastics).

[0003] Place the hand-operated valve body on the conveyor belt, and control a robotic arm to grab the valve body and place it in the machining center. After the machining center finishes processing, the robotic arm will transfer the valve body to the second conveyor belt, and then the second robotic arm will send the valve body into the machine tool. After the machine tool finishes processing the valve body, the robotic arm will take out the valve body and send it to the third conveyor belt.

[0004] Existing manual valve body processing production lines require manual placement of products on a conveyor belt, which involves significant manual labor and reduces processing efficiency over time. Furthermore, they lack the capability to use robotic arms for clamping and transporting. Therefore, this paper proposes a new manual valve body processing production line. Summary of the Invention

[0012] As a preferred embodiment of the manual valve body processing production line of the present invention, the support plate is located on one side of the output end of the robotic arm, the clamping block is rotatably connected in the inner cavity of the square hole of the support plate, and one end of the clamping block extends to one side of the support plate.

[0013] As a preferred embodiment of the manual valve body processing production line of the present invention, two double-row gears are rotatably connected to the top of the fixed plate, and slide rods are symmetrically installed on opposite sides of the two fixed blocks, and the single-sided toothed plate is slidably connected to the outside of the slide rods.

[0014] As a preferred embodiment of the manual valve body processing production line of the present invention, a second spring is symmetrically arranged on one side of the single-sided toothed plate, the second spring is located outside the slide rod, and the double-sided toothed plate is located on the top of the receiving plate.

[0016] As a preferred embodiment of the manual valve body processing production line of the present invention, a limiting block is fixedly installed on one side of the clamping plate, and the limiting block is symmetrically provided with insertion pins inside.

[0017] As a preferred embodiment of the manual valve body processing production line of the present invention, a pull plate is fixedly connected to one side of the plug pin, a limit ring is fixedly installed on the outer surface of the plug pin, and a third spring is provided on one side of the limit ring.

[0018] As a preferred embodiment of the manual valve body processing production line of the present invention, both of the plug pins are slidably connected inside the limiting block, the third spring is located outside the plug pins, and the plug pins are movably inserted into the circular groove.

[0019] (III) Beneficial Effects This invention provides a production line for processing manual valve bodies. It has the following advantages: 1. The quick-release mechanism facilitates the fixing of the support plate onto the output end of the robotic arm, enabling rapid assembly and disassembly. The support plate is moved closer to the output end of the robotic arm, and the clamping plate is aligned with the corresponding limit strip. The clamping plate is then clamped onto the opposite side of the two limit strips. At this point, the bent end of the clamping block slides downwards from the inclined surface of the trapezoidal block until it is clamped onto the trapezoidal block. Under the action of the two first springs, the trapezoidal block is stably clamped onto the trapezoidal block. After installation, the straight ends of the two clamping blocks are manually rotated simultaneously towards each other around the corresponding pivot, removing the bent end of the clamping block from the trapezoidal block and removing the support plate from the output end of the robotic arm. This facilitates the assembly and disassembly of the support plate, improving the robotic arm's ability to adapt to different support plates when processing different types of valve bodies.

[0020] 2. Through the action of the clamping mechanism, the processed valve body can be clamped and transferred. The operation of the control cylinder is controlled. The output end of the cylinder drives the double-sided toothed plate to move, thereby driving the two double-row gears to rotate inward at the same time. The two double-row gears drive the corresponding single-sided toothed plates to move towards each other on the slide rod. The single-sided toothed plates drive the clamping plates to move through the receiving plate. With the assistance of the two clamping plates, the two clamping plates are clamped on the outside of the valve body, thus clamping the valve body and facilitating the clamping of the valve body.

[0021] 3. The adjusting mechanism facilitates the adjustment of the position of the clamping plate on the receiving plate. Pulling the pull plate outward causes the two insertion pins to move simultaneously. The insertion pins then move the corresponding limit rings, pulling the clamping plate out of the circular groove and moving it towards the opening of the T-slot. Once the clamping plate is in the appropriate position, the tension applied to the pull plate is released. Under the action of the third spring, the insertion pins are pushed into the circular groove. This facilitates the adjustment of the clamping plate position and also allows the cylinder to be removed from one side of the receiving plate. Different clamping plates can be replaced according to different valve body shapes. Attached Figure Description

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0033] Example 1 Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This is the first embodiment of the present invention. This embodiment provides a manual valve body processing production line, including symmetrically arranged robotic arms 1. The output end of the robotic arms 1 is provided with a quick release mechanism 2. A clamping mechanism 3 is provided on one side of the quick release mechanism 2. An adjustment mechanism 4 is symmetrically arranged on one side of the clamping mechanism 3. Machining centers 5 and machine tools 7 are evenly distributed and symmetrically arranged on both sides of the robotic arms 1. Multiple conveyor belts 6 are evenly distributed on opposite sides of the two machining centers 5.

[0034] The quick-release mechanism 2 includes a support plate 201. Longitudinal plates 203 are evenly distributed and symmetrically installed on one side of the support plate 201. Square holes are symmetrically opened on one side of the support plate 201. A rotating shaft 208 is movably installed on the inner surface of the square hole. A locking block 207 is fixedly connected to the outer surface of the rotating shaft 208. A locking plate 204 is symmetrically installed on the same side of the support plate 201 and the longitudinal plate 203. Limiting strips 205 that are adapted to the locking plate 204 are evenly distributed and symmetrically arranged around the output end of the robotic arm 1. Trapezoidal blocks 206 that are adapted to the locking block 207 are symmetrically arranged on the outer surface of the robotic arm 1.

[0035] Specifically, when the support plate 201 is attached to the output end of the robotic arm 1, the clamping plate 204 is clamped on the opposite side of the two limit bars 205. At this time, the clamping block 207 is clamped on one side of the trapezoidal block 206. After both clamping blocks 207 are clamped on the trapezoidal block 206, it is convenient to quickly install the support plate 201 on the output end side of the robotic arm 1.

[0036] Specifically, a horizontal plate 202 is symmetrically installed on one side of the support plate 201, and a first spring 209 is symmetrically arranged on one side of the horizontal plate 202. The other end of the first spring 209 is fixedly installed on one side of the locking block 207. Under the action of the two first springs 209, the bent end of the locking block 207 can be locked on the trapezoidal block 206, so that the support plate 201 is stable on the output end side of the robotic arm 1.

[0037] Specifically, the quick-release mechanism 2 also includes a limiting plate 210 fixedly installed on one side of the two longitudinal plates 203. The limiting plate 210 is located on one side of the locking block 207. The first spring 209 is at the same horizontal position as the limiting plate 210. Under the action of the first spring 209, after the support plate 201 is disengaged from the output end of the robotic arm 1, the first spring 209 prevents the bent end of the locking block 207 from being pushed excessively, thereby facilitating the next installation of the support plate 201. The support plate 201 is located on one side of the output end of the robotic arm 1, and the locking block 207 is rotatably connected in the square hole cavity of the support plate 201. One end of the locking block 207 extends to one side of the support plate 201.

[0038] Next, move the support plate 201 closer to the output end of the robotic arm 1, and snap the two clamping plates 204 into the corresponding two limiting strips 205 on opposite sides. At this time, after the support plate 201 is completely attached to the output end of the robotic arm 1, the bent end of the clamping block 207 is clamped onto the trapezoidal block 206. Under the action of the first spring 209, the bent end of the clamping block 207 is stabilized on the trapezoidal block 206, completing the installation of the support plate 201. When it is necessary to remove the support plate 201, flip the bent end of the clamping block 207 outward around the pivot 208 from the trapezoidal block 206, so that the bent end of the clamping block 207 is detached from the trapezoidal block 206. At this time, the support plate 201 can be moved out from the output end of the robotic arm 1.

[0039] Example 2 Reference Figure 3 , Figure 6 and Figure 7 This is the second embodiment of the present invention, which is based on the previous embodiment. The clamping mechanism 3 includes a fixing plate 302 fixedly installed on one side of the support plate 201. Double-row gears 304 are symmetrically arranged on the top of the fixing plate 302. Double-sided toothed plates 303 are arranged on opposite sides of the two double-row gears 304. Fixing blocks 305 are symmetrically installed on the top of the fixing plate 302. Single-sided toothed plates 308 are symmetrically installed on opposite sides of the two fixing blocks 305. A receiving plate 309 is arranged on one side of the single-sided toothed plate 308. A clamping plate 310 is installed on one side of the receiving plate 309.

[0040] Specifically, when the double-sided toothed plate 303 moves toward the clamping plate 310, it can drive the two double-row gears 304 to rotate simultaneously, and the two double-row gears 304 rotate in opposite directions, causing the two single-sided toothed plates 308 to move in opposite directions. After the two clamping plates 310 are moved to their maximum positions, the two single-sided toothed plates 308 are controlled to move in opposite directions, and the valve body is clamped under the action of the two clamping plates 310.

[0041] Specifically, two double-row gears 304 are rotatably connected to the top of the fixed plate 302, and slide rods 307 are symmetrically installed on opposite sides of the two fixed blocks 305. A single-sided toothed plate 308 is slidably connected to the outside of the slide rods 307. Under the action of the two slide rods 307, the single-sided toothed plate 308 can move stably when it moves.

[0042] Specifically, a second spring 306 is symmetrically arranged on one side of the single-sided toothed plate 308. The second spring 306 is located outside the slide rod 307. The double-sided toothed plate 303 is located on the top of the receiving plate 309. When the double-sided toothed plate 303 extends forward, it passes over the top of the receiving plate 309 without hindering the movement of the double-sided toothed plate 303.

[0043] Specifically, the clamping mechanism 3 also includes a cylinder 301 fixedly installed on one side of the support plate 201, a double-sided toothed plate 303 fixedly installed at the output end of the cylinder 301, two double-row gears 304 meshing with the double-sided toothed plate 303, and the double-sided toothed plate 303 meshing with the single-sided toothed plate 308.

[0044] Furthermore, the operation of the control cylinder 301 is controlled. The output end of the cylinder 301 drives the double-sided toothed plate 303 to move. The double-sided toothed plate 303 drives the two double-row gears 304 to rotate inward simultaneously. The two double-row gears 304 drive the corresponding single-sided toothed plates 308 to move towards each other on the slide rod 307. The single-sided toothed plates 308 drive the corresponding clamping plates 310 to move through the corresponding receiving plates 309. Under the action of the two clamping plates 310, they are clamped on the outside of the valve body to clamp the valve body.

[0045] Example 3 Reference Figure 3 and Figure 8 This is the third embodiment of the present invention, which is based on the previous embodiment. The adjustment mechanism 4 includes a T-shaped block 406 fixedly installed on one side of the clamping plate 310, and a T-shaped groove 408 adapted to the T-shaped block 406 is provided on one side of the receiving plate 309.

[0046] Specifically, with the assistance of the T-shaped block 406, the clamping plate 310 is moved in the T-shaped groove 408, which facilitates the adjustment of the position of the clamping plate 310 and allows the clamping plate 310 to be removed from the receiving plate 309 side for replacement.

[0047] Specifically, a limiting block 401 is fixedly installed on one side of the clamping plate 310. The limiting block 401 has symmetrically arranged insertion pins 402 inside. A number of circular grooves 407 are evenly distributed and symmetrically opened on one side of the receiving plate 309. After pulling out two insertion pins 402 from the circular grooves 407 at the same time and moving the clamping plate 310 to a suitable position, the insertion pins 402 are then inserted into the circular grooves 407 to adjust the appropriate position of the clamping plate 310.

[0048] Specifically, a pull plate 403 is fixedly connected to one side of the insertion pin 402, and a limiting ring 405 is fixedly installed on the outer surface of the insertion pin 402. A third spring 404 is provided on one side of the limiting ring 405. Under the action of the third spring 404, the limiting ring 405 is pushed towards the receiving plate 309, so that the insertion pin 402 is stably inserted into the circular groove 407. Both insertion pins 402 are slidably connected inside the limiting block 401, and the third spring 404 is located outside the insertion pin 402, so that the insertion pin 402 is movably inserted into the circular groove 407.

[0049] Furthermore, manually pull the pull plate 403. The pull plate 403 drives the two insertion pins 402 to move outward simultaneously, pulling the insertion pins 402 out of the circular groove 407. At this time, the insertion pins 402 drive the limiting ring 405 to move. With the assistance of the limiting ring 405, the third spring 404 is compressed and deformed, moving the clamping plate 310 towards the opening of the T-shaped groove 408. The clamping plate 310 drives the T-shaped block 406 to move in the T-shaped groove 408. After the clamping plate 310 is moved to the appropriate position, the pulling force applied to the pull plate 403 is released. Under the action of the third spring 404, the limiting ring 405 is pushed in the opposite direction, so that the insertion pins 402 are inserted into the corresponding circular groove 407, thereby adjusting the position of the clamping plate 310.

[0050] Working principle: The robotic arm 1, machining center 5, conveyor belt 6, and machine tool 7 are all existing structures, and the existing ones are the same. The support plate 201 is moved closer to the output end of the robotic arm 1, and the two clamping plates 204 are clamped into the corresponding two limiting strips 205 on opposite sides. After the support plate 201 is completely attached to the output end of the robotic arm 1, the bent end of the clamping block 207 is clamped onto the trapezoidal block 206. Under the action of the first spring 209, the bent end of the clamping block 207 is stabilized on the trapezoidal block 206, completing the installation of the support plate 201. The hand-operated valve body is first placed on the top of the outermost conveyor belt 6 to control the operation of the first robotic arm 1. The robotic arm 1, through its own operation, moves the robotic arm 1... The output end is positioned directly above the valve body of conveyor belt 6, controlling the operation of cylinder 301. The output end of cylinder 301 drives the double-sided toothed plate 303 to operate. The double-sided toothed plate 303 drives two double-row gears 304 to rotate on the fixed plate 302. The double-row gears 304 drive the corresponding single-sided toothed plate 308 to move inward on the slide rod 307. The single-sided toothed plate 308 drives the receiving plate 309 to move. The receiving plate 309 drives the clamping plates 310 to move towards each other. Under the action of the two clamping plates 310, the two clamping plates 310 are placed on both sides of the valve body. After the two clamping plates 310 clamp the valve body on the outside, the valve body is clamped. After clamping, the valve body is placed sequentially on two machining centers 5. In the process, after the valve body in machining center 5 is processed, the control robot arm 1 places the processed valve body on the conveyor belt 6 on one side of the two robot arms 1. Then, the control robot arm 1 runs to clamp the valve body from the middle conveyor belt 6 and place it in machine tool 7 for processing. After processing, the valve body is placed on the outermost conveyor belt 6. When it is necessary to adjust the distance between the two cylinders 301 or to clamp a larger valve body, the pull plate 403 is manually pulled outward. The pull plate 403 drives the two insertion pins 402 to move simultaneously, pulling the insertion pins 402 out of the circular groove 407. The insertion pins 402 drive the limit ring 405 to move, and the limit ring 405 assists in the movement of the valve body. With the assistance of the third spring 404, the third spring 404 is compressed and deformed, causing the two clamping plates 310 to move toward the openings of the corresponding T-shaped grooves 408. The clamping plates 310 drive the T-shaped blocks 406 to move in the T-shaped grooves 408. After the clamping plates 310 are moved to the appropriate position, the tension applied to the pull plate 403 is released. Under the action of the third spring 404, the limiting ring 405 is pushed in the opposite direction, so that the insertion pin 402 is inserted into the corresponding circular groove 407. The position of the clamping plates 310 can be adjusted. When it is necessary to replace different clamping plates 310 to clamp different valve bodies, the above method can be used to remove the clamping plates 310 from the receiving plate 309 side and replace them with different clamping plates 310.
