Description

Technical Field

[0002] A hobbing machine is one of the most widely used machine tools in gear processing machine tools. Straight teeth, helical cylindrical gears can be cut on a hobbing machine, and worm wheels, sprocket wheels, etc. can also be processed. It is a gear processing machine tool that uses a hob to process straight teeth, helical teeth, and herringbone teeth cylindrical gears and worm wheels by the generating method.

[0003] When the existing hobbing machine is working, it usually requires workers to manually load and unload. When workers manually place raw materials, they also need to control the equipment to clamp the raw materials. Operational errors during the placement process may cause harm to workers. Moreover, when manually loading and unloading, usually one worker is responsible for multiple devices, making it difficult to replace the workpieces in the hobbing machine in a timely manner, affecting production efficiency. In addition, the existing hobbing machines usually only process workpieces and cannot synchronously detect the processed workpieces.

[0014] Optionally, a horizontal baffle is provided on the top of the storage box.

[0015] The beneficial effects of the present invention are: 1. The present application can drive the mobile processing mechanism to operate through a reciprocating screw. When the mobile processing mechanism drives the workpiece to pass through the gear hobbing cutter, the gear hobbing cutter processes the workpiece. The processed workpiece will pass through a rotating detection ring. The rotating detection ring can detect the workpiece in time, thereby realizing the function of real-time monitoring of the processed workpiece.

[0016] 2. The sliding clamping block and the suction cup cooperate to clamp the workpiece from both ends, and the clamping arc surface on the sliding clamping block can just fit the outer wall of the workpiece. When the reciprocating screw rotates, it can drive the spline shaft to rotate through the power gear, driven gear and transmission gear. Then the spline shaft will drive the clamping assembly to rotate through the connecting shaft, and the unprocessed workpiece in the clamping assembly will also rotate accordingly, realizing the function of rotating the workpiece during the movement.

[0017] 3. When the processed workpiece fails the inspection, the workpiece will be stuck in the rotating inspection ring. Then, with the cooperation of the annular inclined surface and the support inclined block, the sliding clamping block will loosen the unqualified workpiece, and the unqualified workpiece will slide down along the first discharge arc surface, realizing the function of automatically sending out the unqualified workpiece.

[0018] 4. When the sliding clamping block releases a non-conforming workpiece, the sliding block just gets stuck in the card slot. After the non-conforming workpiece being processed disengages from the sliding clamping block, under the action of the sliding block, the connecting spring cannot push the sliding connecting rod to slide and reset along the connecting sleeve, which can prevent the sliding connecting rod and the sliding stop rod from resetting simultaneously and colliding, thereby damaging the equipment.

[0019] 5. After the workpiece being processed is detected as qualified, the workpiece will pass through the rotating detection ring. Subsequently, under the cooperation of the expanding inclined plane and the annular expanding block, the sliding clamping block will release the qualified workpiece. Then the qualified workpiece will slide down along the second discharge arc surface, realizing the function of automatically discharging the qualified workpiece.

[0020] 6. When the moving mounting plate moves along the reciprocating lead screw, the L-shaped fixed connecting rod will push the wedge-shaped slider to slide downward through the wedge-shaped rod. After the wedge-shaped slider disengages from the sliding stop rod, under the elastic force of the compression spring, the sliding rod, the sliding frame and the sliding sleeve will quickly slide towards the side baffle. When the convex part on the sliding sleeve slides along the inclined slideway in the rotating feeding plate, the rotating feeding plate will rotate downward along the fixed rod. The downward rotation of the rotating feeding plate will first press the unprocessed workpiece in the storage box downward. When the sliding sleeve slides out of the rotating feeding plate, the rotating feeding plate stops rotating, and at this time the unprocessed workpiece just disengages from the rotating feeding plate. At this time, under the push of the pushing spring, the telescopic sliding pushing frame will send the unprocessed workpiece into the rotating feeding plate, avoiding hindering the movement of the moving mounting plate. When the sliding stop rod moves and resets along the guide rod, the sliding stop rod will push the sliding frame, the sliding rod and the sliding sleeve to move away from the side baffle through the wedge-shaped slider. When the sliding sleeve slides along the rotating feeding plate, it will make it rotate upward around the fixed rod. At the same time, the rotating feeding plate will send a new workpiece between the suction cup and the rotating disk, realizing the function of automatic feeding.

[0021] 7. After the sliding stop rod moves past the wedge-shaped block, if the sliding stop rod wants to slide and reset along the guide rod again, it will be blocked by the sliding limit rod and the wedge-shaped block, so as to prevent the sliding rod and the sliding sleeve from resetting too quickly, causing the workpiece to collide with the moving mounting frame and the devices thereon when the rotating feeding plate conveys the workpiece. When the moving mounting frame moves and resets, the fixed push rod will push the sliding limit rod to slide along the fixed column and the side baffle. At this time, the wedge-shaped block no longer blocks the sliding stop rod, and the sliding stop rod will drive the sliding rod and the sliding sleeve to slide and reset, while making the rotating feeding plate send the workpiece between the rotating disk and the suction cup.

[0022] 8. A horizontal baffle is provided at the top of the storage box, which can prevent the workpiece from being pushed outwards by the telescopic sliding pushing frame. A deep groove is opened on one side of the storage box away from the arc-shaped guide plate, which can provide enough rotating space for the rotating feeding plate. The arc-shaped guide plate can support the workpiece from the side, preventing the workpiece in the rotating feeding plate from falling out directly. Brief Description of the Drawings

Detailed implementation manners

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation manners.

[0038] Embodiment 1: An automatic loading and unloading hobbing machine for shaft machining with detection, as Figures 1-13As shown in the figure, it includes a fixed base plate 1, a fixed slide rail 101, side baffles 102, a support frame 104, a hobbing cutter 105, a reciprocating lead screw 2, a moving plate 201, a moving mounting plate 202, a connecting sleeve 203 and a moving processing mechanism. A fixed slide rail 101 is fixedly connected to the fixed base plate 1. The fixed slide rail 101 is L-shaped. Side baffles 102 are fixedly connected to the fixed base plate 1. A support frame 104 is provided on one side of the fixed base plate 1. The support frame 104 can move freely under the control of an external force. A hobbing cutter 105 is rotatably connected to the support frame 104. The hobbing cutter 105 is connected to an external power source. A reciprocating lead screw 2 is rotatably connected between the fixed slide rail 101 and the side baffles 102. The reciprocating lead screw 2 is fixedly connected to the connecting shaft of an external motor. A moving plate 201 and a moving mounting plate 202 are slidably connected to the fixed slide rail 101. The moving plate 201 and the moving mounting plate 202 are connected to the reciprocating lead screw 2 through the same nut. When the reciprocating lead screw 2 rotates, the moving plate 201 and the moving mounting plate 202 can reciprocate on the reciprocating lead screw 2. A connecting sleeve 203 is fixedly connected between the moving plate 201 and the moving mounting plate 202. The inside of the connecting sleeve 203 is hollow. The moving processing mechanism is installed on the reciprocating lead screw 2 and the side baffles 102. The moving processing mechanism is used to drive the workpiece to move and enable the hobbing cutter 105 to process the workpiece.

[0039] During processing, first place the unprocessed workpiece into the moving processing mechanism, and then start the external motor. The external motor will drive the moving processing mechanism to operate through the reciprocating lead screw 2, and the hobbing cutter 105 on the support frame 104 will operate. At this time, the support frame 104 and the hobbing cutter 105 will move closer to the workpiece. When the moving processing mechanism drives the workpiece past the hobbing cutter 105, the hobbing cutter 105 will process the unprocessed workpiece. When the position on the workpiece that needs to be processed is completed, the support frame 104 and the hobbing cutter 105 will move away from the workpiece. When the moving processing mechanism moves back to its original position along the reciprocating lead screw 2, turn off the external motor and take out the processed workpiece to realize the function of processing the workpiece.

[0040] Embodiment 2: On the basis of Embodiment 1, as Figures 2-5As shown, the mobile processing mechanism includes a driving gear 2001, a driven gear 2002, a transmission gear 2003, a connecting spring 2031, a sliding connecting rod 204, a rotating disc 205, a guiding rod 3, a sliding stop lever 301, a return spring 302, a sliding guide rod 303, a spline shaft 304, a connecting shaft 305 and a clamping assembly. One end of the reciprocating lead screw 2 close to the side baffle 102 is fixedly connected with the driving gear 2001. The side baffle 102 is rotatably connected with the driven gear 2002 and the transmission gear 2003. The driven gear 2002 is meshed with the driving gear 2001 and the transmission gear 2003 respectively. The driving gear 2001, the driven gear 2002 and the transmission gear 2003 are distributed in the vertical direction. The driving gear 2001 is located at the bottommost, and the driven gear 2002 is located between the driving gear 2001 and the transmission gear 2003. A sliding connecting rod 204 is slidably connected in the connecting sleeve 203. A connecting spring 2031 is arranged between the sliding connecting rod 204 and the connecting sleeve 203. Two ends of the connecting spring 2031 are respectively fixed on the connecting sleeve 203 and the sliding connecting rod 204. The connecting spring 2031 is used for pushing the sliding connecting rod 204 outwards from the connecting sleeve 203. One end of the sliding connecting rod 204 away from the connecting sleeve 203 is fixedly connected with the rotating disc 205. The guiding rod 3 is fixedly connected to the side baffle 102. A sliding stop lever 301 is slidably connected to the guiding rod 3. The sliding stop lever 301 is slidably connected to the side baffle 102 through the sliding guide rod 303. A through hole large enough for the sliding stop lever 301 to pass through is formed in the side baffle 102. A return spring 302 is arranged between the sliding stop lever 301 and the side baffle 102. The return spring 302 is sleeved on the guiding rod 3. Two ends of the return spring 302 are respectively fixed on the sliding stop lever 301 and the side baffle 102. A spline shaft 304 is rotatably connected to the sliding stop lever 301. The spline shaft 304 is meshed with the transmission gear 2003. When the reciprocating lead screw 2 rotates, the spline shaft 304 will rotate accordingly. A connecting shaft 305 is fixedly connected to the spline shaft 304. The clamping assembly is installed on the rotating disc 205 and the connecting shaft 305. The spline shaft 304 can drive the clamping assembly and the rotating disc 205 to rotate through the connecting shaft 305. The clamping assembly is used for clamping the workpiece to be processed.

[0041] When placing the workpiece, the clamping component clamps the workpiece. Subsequently, when the reciprocating lead screw 2 rotates, the power gear 2001 will drive the spline shaft 304 to rotate through the driven gear 2002 and the transmission gear 2003. The spline shaft 304 will drive the clamping component and the rotating disk 205 to rotate through the connecting shaft 305. The rotating disk 205 will drive the connecting sleeve 203 to rotate through the sliding connecting rod 204 and the connecting spring 2031. When the reciprocating lead screw 2 rotates, the moving plate 201 and the moving mounting plate 202 will move along the reciprocating lead screw 2. The connecting sleeve 203 will move accordingly and push the rotating disk 205 to move through the connecting spring 2031 and the sliding connecting rod 204. The rotating disk 205 will drive the clamping component and the spline shaft 304 to move towards the side baffle 102. Driven by the spline shaft 304, the sliding stop rod 301 will slide along the guide rod 3 and compress the return spring 302. The sliding guide rod 303 will slide outwards along the side baffle 102. When the moving mounting plate 202 moves to one end of the reciprocating lead screw 2, as the reciprocating lead screw 2 continues to rotate, the moving mounting plate 202 will push the moving plate 201 to move away from the side baffle 102 through the connecting sleeve 203. The connecting sleeve 203 and the devices thereon will also move and reset accordingly. Under the elastic force of the return spring 302, the sliding stop rod 301 and the devices thereon will slide and reset along the guide rod 3. When the moving plate 201 moves and resets, the external motor is turned off. The workpiece in the clamping component can rotate while moving, realizing the functions of clamping, driving the workpiece to move and rotate.

[0042] As Figure 2 and Figure 5 shown, the clamping component includes a sliding clamping block 2051, a clamping spring 2052, a clamping arc surface 2054 and a suction cup 3051. A sliding clamping block 2051 is slidably arranged in the rotating disk 205. There are three sliding clamping blocks 2051 in total, and the three sliding clamping blocks 2051 are evenly distributed in the rotating disk 205. A clamping spring 2052 is arranged between the sliding clamping block 2051 and the rotating disk 205. The two ends of the clamping spring 2052 are respectively fixed on the sliding clamping block 2051 and the rotating disk 205. A clamping arc surface 2054 is arranged on the sliding clamping block 2051, and the clamping arc surface 2054 is attached to the outer wall of the workpiece. A suction cup 3051 is installed on the connecting shaft 305, and the suction cup 3051 can adsorb at one end of the workpiece away from the rotating disk 205.

[0043] During placement, one end of the workpiece is placed between the three sliding clamping blocks 2051 on the rotating disk 205. Subsequently, the sliding stop lever 301 is pushed to slide a short distance along the guide rod 3 to compress the return spring 302, so that the other end of the workpiece contacts the suction cup 3051. Then, the sliding stop lever 301 is released, and the suction cup 3051 will adsorb on the workpiece. The three sliding clamping blocks 2051 will clamp one end of the workpiece through the clamping arc surface 2054 under the elastic force of the clamping spring 2052. With the cooperation of the sliding clamping blocks 2051 and the suction cup 3051, the function of clamping the workpiece is realized.

[0044] Embodiment 3: On the basis of Embodiment 2, as Figure 12 shown, it further includes a mounting bracket 6 and a rotation detection ring 601. The mounting bracket 6 is fixedly connected to the side baffle 102. The rotation detection ring 601 is rotatably connected inside the mounting bracket 6. The rotation detection ring 601 is replaceable to detect different products. The spline shaft 304 matches the rotation detection ring 601.

[0045] During the rotational movement of the spline shaft 304, the rotation detection ring 601 will rotate inside the mounting bracket 6. When the workpiece is processed, the processed workpiece will gradually move to the position of the rotation detection ring 601. Since the processed workpiece will still rotate, after the processed workpiece contacts the rotation detection ring 601, if the processed workpiece matches the rotation detection ring 601, the workpiece will pass through the rotation detection ring 601 during rotation. If the processed workpiece does not match the rotation detection ring 601, the workpiece will not be able to pass through the rotation detection ring 601, realizing the function of detecting the processed workpiece.

[0046] As Figure 5 、 Figure 11 and Figure 12 shown, it further includes an annular inclined surface 2024, a spreading inclined block 2053 and a first discharge arc plate 603. The annular inclined surface 2024 is fixedly connected to the side of the movable mounting plate 202 close to the rotating disk 205. The spreading inclined block 2053 is fixedly connected to the rotating disk 205. The spreading inclined block 2053 can slide along the outer surface of the annular inclined surface 2024 to loosen the sliding clamping block 2051. The first discharge arc plate 603 is fixedly connected to the fixed bottom plate 1. The unqualified workpieces will slide outwards along the first discharge arc plate 603 after being loosened.

[0047] When the workpiece cannot match the rotating detection ring 601, the workpiece will get stuck at the rotating detection ring 601 and stop moving towards the side baffle 102. At this time, since the moving mounting plate 202 will continue to move along the reciprocating lead screw 2, the workpiece will push the sliding connecting rod 204 to slide along the connecting sleeve 203 and compress the connecting spring 2031 through the rotating disk 205. When the expanding inclined block 2053 on the sliding clamping block 2051 contacts the annular inclined surface 2024, the sliding clamping blocks 2051 will separate from each other and compress the clamping spring 2052. At the same time, the workpiece will come out of the three sliding clamping blocks 2051. Subsequently, under the action of the gravity of the workpiece itself, the workpiece will break free from the suction cup 3051. Then the workpiece will fall on the first discharge arc plate 603 and slide down, realizing the function of automatically sending out the unqualified workpieces detected.

[0048] As Figure 4 and Figure 13 shown, it further includes a clamping groove 2032, a sliding clamping block 2041, a supporting spring 2042, a straight column 7, a sliding push rod 701 and a moving spring 702. The connecting sleeve 203 is provided with a clamping groove 2032. A sliding clamping block 2041 is slidably connected inside the sliding connecting rod 204. The sliding clamping block 2041 is slightly smaller than the clamping groove 2032. A supporting spring 2042 is provided between the sliding clamping block 2041 and the sliding connecting rod 204. The supporting spring 2)42 can push the sliding clamping block 2041 outwards from the sliding connecting rod 204. Both ends of the supporting spring 2042 are respectively fixed on the sliding clamping block 2041 and the sliding connecting rod 204. A straight column 7 is fixedly connected to the fixed bottom plate 1. A sliding push rod 701 is slidably connected to the straight column 7. A downward convex block is provided in the middle of the bottom surface of the sliding push rod 701. The convex block in the middle of the bottom surface of the sliding push rod 701 can push the sliding clamping block 2041 out of the clamping groove 2032. A moving spring 702 is provided between the sliding push rod 701 and the straight column 7. Both ends of the moving spring 702 are respectively fixed on the sliding push rod 701 and the straight column 7.

[0049] When the workpiece is detected as unqualified, the sliding link 204 will slide along the connecting sleeve 203 and compress the connecting spring 2031. When the workpiece disengages from the sliding clamping block 2051, the sliding block 2041 inside the sliding link 204 just moves to the card slot 2032 on the connecting sleeve 203. Under the elastic force of the supporting spring 2042, the sliding block 2041 will be stuck in the card slot 2032 to prevent the connecting shaft 305 and the sliding link 204 from resetting simultaneously and causing a collision when the workpiece drops downward. Subsequently, when the moving plate 201 and the moving mounting plate 202 move back to their original positions, the sliding push rod 701 first slides upward along the vertical column 7 under the push of the moving plate 201 and compresses the moving spring 702. When the sliding push rod 701 disengages from the moving plate 201, under the push of the moving spring 702, the sliding push rod 701 will contact the connecting sleeve 203. When the card slot 2032 on the connecting sleeve 203 moves to the position of the sliding push rod 701, under the elastic force of the moving spring 702, the sliding push rod 701 will push the sliding block 2041 downward from the card slot 2032 and cause the supporting spring 2042 to contract. At this time, the sliding link 204 will slide outward and reset along the connecting sleeve 203 under the elastic force of the connecting spring 2031. After the sliding clamping block 2051 disengages from the annular inclined surface 2024, under the elastic force of the clamping spring 2052, the sliding clamping block 2051 can move back to its original position along the rotating disk 205.

[0050] As Figure 5 and Figure 12 shown, it further includes a spreading inclined surface 2055, an annular spreading block 602, and a second discharge arc plate 604. An annular spreading block 602 is fixedly connected to one side of the mounting frame 6 away from the side baffle 102. A spreading inclined surface 2055 is fixedly provided on the sliding clamping block 2051. The annular spreading block 602 cooperates with the spreading inclined surface 2055 to release the workpiece from the sliding clamping block 2051. A second discharge arc plate 604 is fixedly connected to the fixed bottom plate 1. The qualified workpiece can slide out along the second discharge arc plate 604.

[0051] When the workpiece is detected as qualified, during the rotation of the workpiece, it will match with the rotating detection ring 601. Subsequently, the workpiece will be inserted into the rotating detection ring 601 and drive it to rotate. When the workpiece completely passes through the rotating detection ring 601, the spreading inclined surface 2055 on the sliding clamping block 2051 will contact the annular spreading block 602 on the mounting frame 6. When the rotating disk 205 continues to move, the sliding clamping blocks 2051 will separate from each other and compress the clamping spring 2052. Subsequently, the workpiece will disengage from the sliding clamping block 2051 and slide downward through the second discharge arc plate 604. When the moving plate 201 moves back to its original position, under the action of the clamping spring 2052, the sliding clamping block 2051 can move back to its original position, realizing the function of sending out the qualified workpiece outward.

[0052] AsFigure 2 and Figures 6-10 As shown, it further includes an L-shaped fixed connecting rod 2022, a wedge-shaped rod 2023, a fixed rod 5, a rotating feeding plate 501, an inclined chute 5011, a sliding rod 502, a sliding frame 503, a wedge-shaped slider 5031, a supporting spring 5032, a sliding sleeve 5033, a compression spring 504, a storage box 505, a telescopic sliding pushing frame 5051, a pushing spring 5052 and an arc-shaped guiding plate 5053. A sliding rod 502 is slidably connected to the side baffle 102. An L-shaped fixed connecting rod 2022 is fixedly connected to the moving mounting plate 202. A wedge-shaped rod 2023 is fixedly connected to the L-shaped fixed connecting rod 2022. A fixed rod 5 is fixedly connected to the fixed bottom plate 1. There are two fixed rods 5. A rotating feeding plate 501 is rotatably connected between the two fixed rods 5. The inside of the rotating feeding plate 501 is hollow. An inclined chute 5011 is provided inside the rotating feeding plate 501. A sliding sleeve 5033 is slidably connected inside the rotating feeding plate 501. The sliding sleeve 5033 is provided with a protruding part. The protruding part on the sliding sleeve 5033 can just slide inside the inclined chute 5011. The sliding sleeve 5033 is fixedly connected to the sliding rod 502. A sliding frame 503 is fixedly connected to the sliding rod 502. A wedge-shaped slider 5031 is slidably connected inside the sliding frame 503. In the initial state, the wedge-shaped slider 5031 is blocked by the sliding stop rod 301. The top surface of the wedge-shaped slider 5031 is an inclined surface. A supporting spring 5032 is provided between the wedge-shaped slider 5031 and the sliding frame 503. The two ends of the supporting spring 5032 are respectively fixed on the wedge-shaped slider 5031 and the sliding frame 503. The wedge-shaped slider 5031 is in sliding contact with the wedge-shaped rod 2023. The wedge-shaped rod 2023 can push the wedge-shaped slider 5031 to slide downward along the sliding frame 503. A compression spring 504 is provided between the sliding frame 503 and the fixed rod 5. The compression spring 504 is sleeved on the sliding rod 502. The two ends of the compression spring 504 are respectively fixed on the sliding frame 503 and the fixed rod 5. A storage box 505 is fixedly connected to the fixed bottom plate 1. The storage box 505 is used to store workpieces to be processed. A telescopic sliding pushing frame 5051 is installed inside the storage box 505. A pushing spring 5052 is provided between the telescopic sliding pushing frame 5051 and the bottom plate of the storage box 505. The pushing spring 5052 can push the workpiece upward through the telescopic sliding pushing frame 5051. The two ends of the pushing spring 5052 are respectively fixed on the telescopic sliding pushing frame 5051 and the bottom plate of the storage box 505. An arc-shaped guiding plate 5053 is provided on one side of the storage box 505 close to the reciprocating lead screw 2. The arc-shaped guiding plate 5053 plays a role of support and guidance.

[0053] In the initial state, the sliding sleeve 5033 is located at the innermost side of the rotating feeding plate 501, and the compression spring 504 is in a contracted state. When the moving mounting plate 202 moves along the reciprocating lead screw 2, the L-shaped fixed connecting rod 2022 will push the wedge-shaped slider 5031 to slide downward along the sliding frame 503 through the wedge-shaped rod 2023 and compress the supporting spring 5032. When the wedge-shaped slider 5031 disengages from the sliding stop lever 301, under the elastic force of the compression spring 504, the sliding rod 502 will drive the sliding frame 503 and the devices thereon to slide in the direction close to the side baffle 102. When the sliding rod 502 drives the sliding sleeve 5033 to slide along the rotating feeding plate 501, the protruding part on the sliding sleeve 5033 will move along the inclined slideway 5011, and at the same time, the rotating feeding plate 501 will rotate downward and disengage from the workpiece. When the compression spring 504 is fully restored, the rotating feeding plate 501 stops rotating. During the downward rotation of the rotating feeding plate 501, the rotating feeding plate 501 will contact the topmost workpiece in the storage box 505, and then the outer wall of the rotating feeding plate 501 will press the workpiece downward, and at the same time, the telescopic sliding pusher frame 5051 and the pusher spring 5052 will contract. When the outer wall of the rotating feeding plate 501 disengages from the workpiece, under the elastic force of the pusher spring 5052, the telescopic sliding pusher frame 5051 will push the workpiece upward and push the workpiece into the rotating feeding plate 501, so that the workpiece fits against the inner wall of the rotating feeding plate 501. When the sliding stop lever 301 moves towards the side baffle 102, the sliding stop lever 301 will contact the wedge-shaped slider 5031, and then the sliding stop lever 301 will push the wedge-shaped slider 5031 downward and make the supporting spring 5032 contract. When the sliding stop lever 301 disengages from the wedge-shaped slider 5031, the supporting spring 5032 will push the wedge-shaped slider 5031 upward to reset. When the sliding stop lever 301 moves back to its original position, the sliding stop lever 301 drives the sliding frame 503 and the sliding rod 502 to move through the wedge-shaped slider 5031. The sliding rod 502 drives the sliding sleeve 5033 to slide along the rotating feeding plate 501, and the protruding part on the sliding sleeve 5033 will move along the inclined slideway 5011, and at the same time, the rotating feeding plate 501 will rotate upward and send the workpiece to between the suction cup 3051 and the rotating disk 205, realizing the function of automatically feeding the workpiece into the equipment.

[0054] As Figure 2 and Figure 3As shown, it also includes a fixed column 103, a fixed push rod 2021, a sliding limit rod 4, a blocking spring 401 and a wedge-shaped block 402. The fixed base plate 1 is fixedly connected to the fixed column 103, and the movable mounting plate 202 is fixedly connected to the fixed column 103 and the side baffle 102. The sliding limit rod 4 is slidably connected to one end of the sliding limit rod 4 close to the side baffle 102. The wedge block 402 can block the sliding baffle 301. The fixed push rod 2021 can push the sliding limit rod 4 to move and disengage the wedge block 402 from the sliding baffle 301. A blocking spring 401 is provided between the sliding limit rod 4 and the fixed column 103 and the side baffle 102. One end of the blocking spring 401 is fixed to the sliding limit rod 4, and the other end of the blocking spring 401 is fixed to the side baffle 102 or the fixed column 103.

[0055] When the sliding stop rod 301 slides along the guide rod 3, the sliding stop rod 301 will contact the wedge-shaped stop block 402, and then the sliding stop rod 301 will push the sliding limit rod 4 to slide along the side baffle 102 and the fixed column 103 through the wedge-shaped stop block 402 and compress the blocking spring 401. When the sliding stop rod 301 is out of contact with the wedge-shaped stop block 402, the sliding limit rod 4 and the wedge-shaped stop block 402 will move and reset under the elastic force of the blocking spring 401. When the workpiece is dropped down after processing, the wedge-shaped stop block 402 blocks the sliding stop rod. When the sliding block rod 301 is reset, the fixed push rod 2021 will contact the sliding limit rod 4 and push it to slide along the fixed column 103 and the side baffle 102. At this time, under the elastic force of the reset spring 302, the sliding block rod 301 will slide and reset along the guide rod 3, thereby preventing the sliding block rod 301 from directly resetting.

[0056] like Figure 10 As shown, a horizontal baffle is provided on the top of the storage box 505; under the elastic force of the push spring 5052, the telescopic sliding push rack 5051 in the storage box 505 always applies an upward thrust to the workpiece, and the horizontal baffle on the top of the storage box 505 can prevent the workpiece from automatically falling out due to the thrust.

Therefore, any equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
