Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and in particular to a vehicle jamming machine with an automatic loading and unloading mechanism and a picking structure. Background Technology

[0002] An automobile is a modern means of transportation that is driven by its own power unit and can travel on land. The advent of automobiles has greatly changed people's travel methods, improved travel efficiency and convenience, and is used not only for daily commuting and travel, but also plays a key role in logistics transportation, business activities and other fields, profoundly affecting modern social life. Automobiles are assembled from a large number of parts, and these parts need to be mass-produced during the production process.

[0003] In traditional machining processes, the loading and unloading of workpieces is usually done manually. Operators need to manually place the workpieces to be processed on the machine tool and then remove them after processing. This manual operation method is not only inefficient but also poses safety hazards, as it is easy to damage the workpieces or injure personnel due to operational errors. With the development of industrial automation technology, some companies have begun to use intelligent robotic arms for loading and unloading. However, robotic arms have complex structures and high costs, making it difficult to meet the needs of small and medium-sized enterprises.

[0004] Therefore, there is an urgent need for a machine that can replace manual loading and unloading operations, simplify the structure, reduce investment and maintenance costs, and is suitable for use by small and medium-sized enterprises. Summary of the Invention

[0005] The purpose of this application is to provide a vehicle jamming machine with an automatic loading and unloading mechanism to solve the problems mentioned in the background art.

[0006] The present application provides a car jamming machine with an automatic loading and unloading structure, which adopts the following technical solution: A car jamming machine with an automatic loading and unloading structure includes a machine tool, a loading and unloading picking unit, an automatic loading unit, and an automatic unloading unit. The loading and unloading picking unit includes a fixed plate fixedly connected to the top of the machine tool. A movable plate is slidably connected to the front of the fixed plate. An M-shaped groove is opened inside the fixed plate. Two inverted V-shaped grooves are opened inside the movable plate. A sliding rod is slidably connected inside each V-shaped groove. A slider is fixedly connected to the back of each sliding rod. The slider is slidably connected inside the M-shaped groove. A first cylinder is fixedly connected to the front of each sliding rod. A clamping assembly is provided at the output end of the first cylinder. A second cylinder is provided on one side of the machine tool. The output end of the second cylinder is fixedly connected to the outer surface of the movable plate. The automatic feeding unit includes a base and a base fixedly connected to the top of the machine tool. The top of the base is provided with a first conveying mechanism. An inclined discharge plate is placed between the output end of the first conveying mechanism and the base. Two symmetrically arranged side plates adapted to the first conveying mechanism and the discharge plate are provided above the machine tool. Two symmetrically arranged notched plates are slidably connected to the upper surface of the base. The ends of the notched plates are fixedly connected to the ends of the side plates by bolts. Notches are opened inside the notched plates. A stop block is slidably connected to the upper surface of the base. A crossbar is fixedly connected to the outer surface of the base. A collar is slidably sleeved on the outer circumference of the crossbar. A connecting rod is fixedly connected between the collar and the stop block. Positioning rings are provided on both sides of the collar. The positioning rings are threadedly connected to the crossbar. An adjustment component is fixedly connected inside the base.

[0007] By adopting the above technical solution, the moving plate is moved by the second cylinder, which causes the slide bar to drive the first cylinder to perform N-shaped reciprocating motion under the combined action of the V-shaped slide groove, the slider and the M-shaped slide groove. This drives the two clamping components to simultaneously complete the clamping and unloading actions, replacing manual loading and unloading operations, saving manpower, improving work efficiency, and at the same time, the structure is simple, the investment cost is low, and it is easy to maintain and operate, making it suitable for small and medium-sized enterprises.

[0008] Preferably, the clamping assembly includes a column fixedly connected to the output end of the first cylinder, a first outer shell fixedly connected to the bottom of the column, a first bidirectional lead screw rotatably connected inside the first outer shell, a drive motor provided at the end of the first bidirectional lead screw, two first threaded tubes threadedly connected to the outer circumference of the first bidirectional lead screw, a first connecting plate fixedly connected to the outer circumference of each first threaded tube, a back plate fixedly connected to the bottom of the first connecting plate, a fixture adapted to the workpiece fixedly connected to the inner side of the back plate by bolts, the position of the notch corresponding to the position of the back plate and the fixture, a first limiting hole opened inside the first outer shell, and the first connecting plate slidably connected to the inside of the first limiting hole; By adopting the above technical solution, the first bidirectional lead screw is driven by the drive motor to rotate, causing the two first threaded tubes to move relative to or towards each other, thereby driving the first connecting plate, back plate and fixture to move, realizing the clamping operation of the workpiece, and then completing the subsequent picking and unloading actions. The first connecting plate slides in the first limiting hole, which can restrict the first threaded tube and prevent the first threaded tube from rotating with the first bidirectional lead screw, so that the back plate and fixture always move and clamp stably laterally. The position of the notch corresponds to the position of the back plate and fixture, so that the back plate and fixture can smoothly pass through the notch to complete the side clamping and loading operation of the workpiece. The back plate and fixture are fixedly connected by bolts, which facilitates the disassembly and replacement of the fixture. Different fixtures can be used according to different workpieces.

[0009] Preferably, a limiting plate is fixedly connected to the outer surface of the slider, and a limiting ring is fixedly connected to the outer circumferential surface of the slide rod. The side of the limiting plate and the limiting ring closest to the fixed plate are in contact with the outer surface of the fixed plate. By adopting the above technical solution, the movement of the slide bar and slider is limited, preventing them from deviating during movement, ensuring that the slide bar slides stably in the V-shaped groove and the slider slides stably in the M-shaped groove, thereby ensuring the normal operation of the loading and unloading unit and improving the accuracy of loading and unloading actions.

[0010] Preferably, the top and bottom of the fixed plate are provided with limiting grooves, and the movable plate is slidably connected to the inside of the limiting grooves; By adopting the above technical solution, the moving plate is restricted to prevent it from shaking or shifting during movement, ensuring the stability of the moving plate and enabling it to move laterally stably at all times. This, in turn, ensures that the loading and unloading unit can accurately perform loading and unloading operations, thereby improving the reliability of equipment operation.

[0011] Preferably, the crossbar has a keyway inside, and a limit key is fixedly connected to the inner wall of the collar, the limit key being slidably connected inside the keyway; By adopting the above technical solution, the movement of the collar on the crossbar is guided and limited, preventing the collar from rotating during movement and ensuring that the collar can only move along the axial direction of the crossbar, thereby improving the stability of the stop and enabling the stop to accurately control the stopping position of the workpiece on the base.

[0012] Preferably, the adjusting assembly includes a second housing, inside which a second bidirectional lead screw is rotatably connected. Two second threaded tubes are threadedly connected to the outer circumferential surface of the second bidirectional lead screw. A second connecting plate is fixedly connected to the outer circumferential surface of each second threaded tube. The top end of the second connecting plate is fixedly connected to the outer surface of a side plate via a fixing member. Two second limiting holes are opened inside the second housing, and the second connecting plate is slidably connected to the inside of the second limiting holes. A worm gear is rotatably connected to the end of the second housing, and a worm wheel is fixedly connected to the end of the second bidirectional lead screw. The worm wheel and the worm gear mesh with each other, and a handwheel is provided at the top end of the worm gear. By adopting the above technical solution, rotating the handwheel drives the worm gear to rotate, which in turn drives the worm wheel and the second bidirectional lead screw to rotate, causing the two second threaded tubes to move relative to or towards each other. This, in turn, drives the side plates to move via the second connecting plate, thereby adjusting the distance between the side plates to meet the conveying and arrangement requirements of workpieces of different sizes. The second connecting plate slides within the second limiting hole, ensuring the stability of the movement. Through the transmission via the worm gear and worm wheel, the self-locking characteristics of the worm gear and worm wheel prevent the second bidirectional lead screw from rotating easily, thus preventing the side plates from shifting easily. This keeps the workpieces stably arranged and moving forward, ensuring the reliability of the automatic feeding unit operation.

[0013] Preferably, four support rods are fixedly connected to the outer surface of the base, and a support ring is slidably sleeved on the outer circumferential surface of each support rod. A support arm is fixedly connected between the support ring and the side plate. By adopting the above technical solution, support is provided for the side plate, enhancing its stability and preventing it from shaking or deforming due to force during workpiece conveying, thus ensuring that the automatic feeding unit can operate stably and reliably.

[0014] Preferably, the automatic unloading unit and the automatic loading unit are respectively disposed on both sides of the machine tool. The automatic unloading unit includes a second conveying mechanism. Both the second conveying mechanism and the first conveying mechanism are motor-driven conveyor belt conveying mechanisms. By adopting the above technical solution, unprocessed workpieces can be clamped and loaded from the base by a clamping component, and processed workpieces can be clamped and placed on the second conveying mechanism for unloading after being clamped by another clamping component. They are then automatically conveyed to the subsequent process, so that loading and unloading actions can be performed simultaneously, thereby improving the automation level and work efficiency of the entire operation process.

[0015] Preferably, the positions of the two clamping components are adapted to the positions of the automatic feeding unit and the automatic unloading unit, respectively.

[0016] By adopting the above technical solution, it is ensured that the clamping component can accurately pick up the workpiece from the automatic feeding unit for feeding, and accurately place the processed workpiece on the automatic unloading unit, thus ensuring the smooth progress of the loading and unloading process.

[0017] Preferably, the machine tool is provided with a clamping mechanism and a movable turning mechanism, and the position of the clamping component is adapted to the position of the clamping mechanism on the machine tool.

[0018] By adopting the above technical solution, the clamping assembly can accurately place the workpiece on the clamping mechanism of the machine tool for turning operations, and remove the finished workpiece from the clamping mechanism, ensuring a close connection between the loading and unloading process and the turning operation. Beneficial effects

[0019] In summary, this application includes at least one of the following beneficial technical effects: This invention provides an automatic loading and unloading machine with a picking structure. The machine uses a second cylinder to drive a moving plate, which in turn causes a slide bar to drive a first cylinder in an N-shaped reciprocating motion under the combined action of a V-shaped slide groove, a slider, and an M-shaped slide groove. This, in turn, drives two clamping components to simultaneously complete the clamping and unloading actions, replacing manual loading and unloading operations, saving manpower, improving work efficiency, and having a simple structure, low investment cost, and easy subsequent maintenance. It is suitable for use by small and medium-sized enterprises.

[0020] This invention provides a car jamming machine with an automatic loading and unloading mechanism. By setting an inclined discharge plate between a first conveying mechanism and a base, providing a side plate adapted to the first conveying mechanism and the discharge plate, and setting a stop on the base, and fixing a notched plate with a notch to the end of the side plate, workpieces can be automatically conveyed on the first conveying mechanism. When workpieces pass the discharge plate, under the influence of the inclination angle and the constraints of the side plate and the notched plate, they will be arranged sequentially on the discharge plate. The bottom workpiece will stop on the base under the action of the stop. The clamping device will pick up the bottom workpiece each time for loading, and subsequent workpieces will move forward synchronously under the action of gravity to automatically fill the gap, realizing automatic workpiece loading. The processed workpieces are clamped by the clamping assembly and placed on the second conveying mechanism for transport to the subsequent process, further saving manpower and improving work efficiency.

[0021] This invention provides a car jamming machine with an automatic loading and unloading mechanism. By rotating the worm gear, the second bidirectional lead screw is driven to rotate under the action of the worm wheel. This causes the second threaded tube to drive the second connecting plate, the fixing part and the side plate to move in opposite directions synchronously. In this way, the spacing of the side plates can be adjusted according to the specifications of the workpiece to meet the processing requirements of different workpieces and improve the flexibility and applicability of the device.

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 10 This application will be described in further detail below.

[0025] Example 1: A car jam machine with automatic loading and unloading mechanism and picking structure, referring to Figure 1 and Figure 2 It includes a machine tool 1, a loading and unloading unit 2, an automatic loading unit 3, and an automatic unloading unit 4.

[0026] Reference Figure 1 , Figure 3 and Figure 4The loading and unloading unit 2 includes a fixed plate 201 fixedly connected to the top of the machine tool 1. A movable plate 202 is slidably connected to the front of the fixed plate 201. An M-shaped groove 203 is opened inside the fixed plate 201. Two inverted V-shaped grooves 204 are opened inside the movable plate 202. A slide rod 205 is slidably connected inside each V-shaped groove 204. A slider 206 is fixedly connected to the back of each slide rod 205. The slider 206 is slidably connected inside the M-shaped groove 203. A first cylinder 207 is fixedly connected to the front of each slide rod 205. A clamping assembly 208 is provided at the output end of the first cylinder 207. A second cylinder 209 is provided on one side of the machine tool 1. The output end of the second cylinder 209 is fixedly connected to the outer surface of the movable plate 202.

[0027] Reference Figure 4 and Figure 5 A limiting plate 210 is fixedly connected to the outer surface of the slider 206, and a limiting ring 211 is fixedly connected to the outer circumferential surface of the slider 205. The limiting plate 210 and the limiting ring 211 are in contact with the outer surface of the fixed plate 201 on the side closest to the fixed plate 201, which limits the movement of the slider 205 and the slider 206, preventing them from deviating during movement, ensuring that the slider 205 slides stably in the V-shaped groove 204 and the slider 206 slides stably in the M-shaped groove 203, thereby ensuring the normal operation of the loading and unloading picking unit 2 and improving the accuracy of the loading and unloading actions.

[0028] Reference Figure 1 , Figure 3 and Figure 4 The fixed plate 201 is provided with limiting grooves 212 at both the top and bottom. The moving plate 202 is slidably connected to the inside of the limiting grooves 212 to restrict the moving plate 202, prevent the moving plate 202 from shaking or deviating during the movement, ensure the stability of the moving plate 202, and promote the moving plate 202 to always move laterally stably, thereby ensuring that the loading and unloading unit 2 can accurately perform loading and unloading operations and improve the reliability of equipment operation.

[0029] Reference Figure 3 , Figure 5 and Figure 6The clamping assembly 208 includes a column 2081 fixedly connected to the output end of the first cylinder 207. A first housing 2082 is fixedly connected to the bottom of the column 2081. A first bidirectional lead screw 2083 is rotatably connected inside the first housing 2082. A drive motor is provided at the end of the first bidirectional lead screw 2083. Two first threaded tubes 2084 are threadedly connected to the outer circumference of the first bidirectional lead screw 2083. A first connecting plate 2085 is fixedly connected to the outer circumference of each first threaded tube 2084. A back plate 2086 is fixedly connected to the bottom of the first connecting plate 2085. A clamp 2087 adapted to the workpiece is fixedly connected to the inner side of the back plate 2086 by bolts. The position of the notch 307 corresponds to the position of the back plate 2086 and the clamp 2087. A first limiting hole 2088 is opened inside the first housing 2082. The first connecting plate 2085 is slidably connected to the inside of the first limiting hole 2088. The first bidirectional lead screw 2083 is driven by the drive motor. Rotating the lead screw 2083 causes the two first threaded tubes 2084 to move relative to or towards each other, thereby driving the first connecting plate 2085, back plate 2086, and clamp 2087 to move, realizing the clamping operation of the workpiece, and then completing the subsequent picking and unloading actions. The first connecting plate 2085 slides in the first limiting hole 2088, which can restrict the first threaded tube 2084 and prevent the first threaded tube 2084 from rotating with the first bidirectional lead screw 2083, so that the back plate 2086 and clamp 2087 always move laterally to clamp. The position of the notch 307 corresponds to the position of the back plate 2086 and clamp 2087, so that the back plate 2086 and clamp 2087 can smoothly pass through the notch 307 to complete the side clamping and loading operation of the workpiece. The back plate 2086 and clamp 2087 are fixedly connected by bolts, which facilitates the disassembly and replacement of the clamp 2087. Different clamps 2087 can be used according to different workpieces.

[0030] Reference Figure 1 and Figure 2 The positions of the two clamping components 208 are adapted to the positions of the automatic feeding unit 3 and the automatic unloading unit 4, respectively, ensuring that the clamping components 208 can accurately clamp the workpiece from the automatic feeding unit 3 for feeding, and accurately place the processed workpiece on the automatic unloading unit 4, thus ensuring the smooth progress of the loading and unloading process.

[0031] Reference Figure 1 and Figure 2 The machine tool 1 is equipped with a clamping mechanism and a movable turning mechanism. The position of the clamping component 208 is adapted to the position of the clamping mechanism on the machine tool 1, so that the clamping component 208 can accurately place the workpiece on the clamping mechanism of the machine tool 1 for turning operations, and remove the finished workpiece from the clamping mechanism, ensuring a close connection between the loading and unloading process and the turning operation.

[0032] Example 2: A car jam machine with automatic loading and unloading mechanism and picking structure, referring to Figure 1 , Figure 7 and Figure 8 The automatic feeding unit 3 includes a base 301 and a base 302 fixedly connected to the top of the machine tool 1. A first conveying mechanism 303 is provided at the top of the base 301. An inclined discharge plate 304 is provided between the output end of the first conveying mechanism 303 and the base 302. Two symmetrically arranged side plates 305 are provided above the machine tool 1 and are adapted to the first conveying mechanism 303 and the discharge plate 304. Two symmetrically arranged notched plates 306 are slidably connected to the upper surface of the base 302. The ends of the notched plates 306 are respectively connected by bolts. The side plate 305 is fixedly connected to the end. The notched plate 306 has a notch 307 inside. The upper surface of the base 302 is slidably connected to the stop 308. The outer surface of the base 302 is fixedly connected to the crossbar 309. The outer circumferential surface of the crossbar 309 is slidably sleeved with a collar 310. A connecting rod 311 is fixedly connected between the collar 310 and the stop 308. Positioning rings 312 are provided on both sides of the collar 310. The positioning rings 312 are threadedly connected to the crossbar 309. An adjustment component 315 is fixedly connected inside the base 301.

[0033] Reference Figure 7 , Figure 8 and Figure 9 The crossbar 309 has a keyway 313 inside. The inner wall of the collar 310 is fixedly connected to a limit key 314. The limit key 314 is slidably connected inside the keyway 313. It guides and limits the movement of the collar 310 on the crossbar 309, preventing the collar 310 from rotating during movement and ensuring that the collar 310 can only move along the axial direction of the crossbar 309. This improves the stability of the stop block 308 and enables the stop block 308 to accurately control the stopping position of the workpiece on the base 302.

[0034] Reference Figure 7 and Figure 10The adjusting assembly 315 includes a second housing 3151. A second bidirectional lead screw 3152 is rotatably connected inside the second housing 3151. Two second threaded tubes 3153 are threadedly connected to the outer circumference of the second bidirectional lead screw 3152. A second connecting plate 3154 is fixedly connected to the outer circumference of each second threaded tube 3153. The top end of the second connecting plate 3154 is fixedly connected to the outer surface of the side plate 305 via a fastener. Two second limiting holes 3155 are formed inside the second housing 3151. The second connecting plate 3154 is slidably connected inside the second limiting holes 3155. A worm gear 3156 is rotatably connected to the end of the second housing 3151. A worm wheel 3157 is fixedly connected to the end of the second bidirectional lead screw 3152. The worm wheel 3157 and the worm gear 3156 mesh with each other. A handwheel is provided at the top of unit 6. Rotating the handwheel drives the worm gear 3156 to rotate, which in turn drives the worm wheel 3157 and the second bidirectional lead screw 3152 to rotate. This causes the two second threaded tubes 3153 to move relative to or towards each other, which in turn drives the side plates 305 to move via the second connecting plate 3154. This allows for adjustment of the distance between the side plates 305 to accommodate the conveying and arrangement requirements of workpieces of different sizes. The second connecting plate 3154 slides within the second limiting hole 3155 to ensure the stability of the movement. The transmission is achieved through the worm gear 3156 and the worm wheel 3157. The self-locking characteristics of the worm wheel 3157 and the worm gear 3156 prevent the second bidirectional lead screw 3152 from rotating easily, thereby preventing the side plates 305 from shifting easily. This ensures that the workpieces are always stably arranged and moved forward, guaranteeing the reliability of the automatic feeding unit 3.

[0035] Reference Figure 2 and Figure 7 Four support rods 316 are fixedly connected to the outer surface of the base 301. Each support rod 316 has a support ring 317 slidably sleeved on its outer circumferential surface. Support arms 318 are fixedly connected between the support ring 317 and the side plate 305, providing support for the side plate 305, enhancing the stability of the side plate 305, preventing the side plate 305 from shaking or deforming due to force during workpiece conveying, and ensuring that the automatic feeding unit 3 can operate stably and reliably.

[0036] Reference Figure 1 , Figure 2 and Figure 7Automatic unloading unit 4 and automatic loading unit 3 are respectively arranged on both sides of machine tool 1. Automatic unloading unit 4 includes a second conveying mechanism 401. Both the second conveying mechanism 401 and the first conveying mechanism 303 are motor-driven conveyor belt conveying mechanisms. Unprocessed workpieces can be clamped and loaded from the base 302 by a clamping component 208. Processed workpieces can be clamped by another clamping component 208 and placed on the second conveying mechanism 401 for unloading, and automatically conveyed to the subsequent process. This allows the loading and unloading actions to be performed simultaneously, improving the automation level and work efficiency of the entire operation process.

[0037] The implementation principle of this application embodiment is as follows: During operation, the workpiece is placed on the first conveying mechanism 303, which conveys the workpiece to the discharge plate 304. The discharge plate 304 is inclined. Under the influence of the inclination angle and the constraints of the two side plates 305, the notched plate 306 with notches 307, and the stop block 308, the workpieces are arranged sequentially on the discharge plate 304. The bottom workpiece will stop on the base 302 under the action of the stop block 308. The clamping component 208 clamps the bottom workpiece away for loading each time. Subsequent workpieces will move forward synchronously under the action of gravity to automatically fill the gap, realizing automatic loading of workpieces. The stop block 308 on the base 302 can control the stopping position of the workpiece on the base 302. Two positioning rings 312 axially restrict the collar 310. Rotating the positioning rings 312 adjusts the collar 310 to a suitable position, allowing the position of the stop block 308 to be adjusted via the connecting rod 311, thereby controlling the workpiece's stopping position on the base 302. When it is necessary to adjust the spacing of the side plates 305 to accommodate workpieces of different sizes, rotating the handwheel drives the worm gear 3156 to rotate. The worm gear 3156 drives the worm wheel 3157 and the second bidirectional lead screw 3152 to rotate. The second bidirectional lead screw 3152 drives the second connecting plate 3154, the fixing part, and the side plates 305 to move through the second threaded tube 3153, thereby adjusting the distance between the side plates 305. When the loading and unloading pickup unit 2 is working, the second cylinder 209 is started, and its output... The end-driven moving plate 202 moves laterally and stably within the limiting groove 212 of the fixed plate 201. During the movement of the moving plate 202, the inverted V-shaped slide groove 204 inside it drives the slide rod 205 to move. The slider 206 on the back of the slide rod 205 slides within the M-shaped slide groove 203 inside the fixed plate 201. Under the combined action of the V-shaped slide groove 204, the slider 206, and the M-shaped slide groove 203, the slide rod 205 drives the first cylinder 207 to perform an N-shaped reciprocating motion, thereby causing the clamping assembly 208 to perform an N-shaped reciprocating motion. During the N-shaped reciprocating motion of the clamping assembly 208, the clamp 2087 of one of the clamping assemblies 208 removes the unprocessed workpiece at the bottom of the base 302. At this time, the other clamping assembly... The clamp 2087 of part 208, in conjunction with the driving displacement of the first cylinder 207, removes the processed workpiece. Then, the second cylinder 209 drives the moving plate 202 to move back. One clamping component 208 moves the unprocessed workpiece to the clamping mechanism of the machine tool 1 in conjunction with the first cylinder 207. The other clamping component 208 removes the processed workpiece and places it on the second conveying mechanism 401 for subsequent processes, completing the synchronous automatic loading and unloading operation. When the clamping component 208 is working, the drive motor drives the first bidirectional lead screw 2083 to rotate, causing the two first threaded tubes 2084 to move relative to or towards each other, thereby driving the first connecting plate 2085, the back plate 2086 and the clamp 2087 to move, realizing the clamping operation of the workpiece.
