[0001] The invention belongs to the technical field of precision casting, and in particular is an automatic conveying and punching device for a precision cast speed reducer housing. Background Art

[0002] Precision casting technology is widely used in many high-end manufacturing fields because it can produce parts with complex shapes and high precision. Among them, the speed reducer housing is a key mechanical component, and there are strict requirements for its quality and processing accuracy. With the intensification of market competition and the pursuit of production efficiency, traditional manual handling and simple mechanical processing methods can no longer meet the needs of modern manufacturing for high efficiency and high precision production. In order to meet this challenge, the automatic handling and stamping device for precision casting speed reducer housing came into being. This device combines a variety of advanced technologies such as automatic handling, mechanical processing and quality inspection, aiming to achieve a fully automated production process from casting to processing. Through automated handling, the possible damage to parts and loss of processing accuracy during manual handling can be reduced, while improving production efficiency and reducing labor intensity. The automatic handling and stamping device usually has the functions of automatic identification and grasping of parts, precise handling, integrated stamping processing, real-time quality inspection and human-computer interaction.

[0003] Most of the existing automatic handling and stamping devices for precision-cast speed reducer housings will cause the position of the workpiece to shift during stamping. At the same time, during the stamping process, the device is easily vibrated due to the impact force, thereby affecting the molding effect of the device. At the same time, after the stamping is completed, the staff is required to unload the molded parts, which not only poses a safety hazard but also reduces the working efficiency of the device. Therefore, an automatic handling and stamping device for precision-cast speed reducer housings is proposed, which has the effects of stamping after fixing, buffering during the stamping process, and facilitating the unloading of molded parts. Summary of the invention

The present invention provides an automatic handling and stamping device for precision cast speed reducer housings.

[0006] Preferably, the top of the piston rod passes through the inner wall of the sealing groove and the bottom of the anti-collision pad to extend above the anti-collision pad, the vent hole is connected to the four sealing grooves, the two exhaust holes pass through the lower die base and the molding block to extend above the molding block, the anti-collision pad is located between the buffer plate and the lower die base, the molding block is located inside the buffer plate, and the buffer plate and the molding block are slidably connected.

[0007] Preferably, the main body mechanism includes a base, a loading plate is fixedly connected to the top of the base, a unloading plate is fixedly connected to the top of the base, and two automatic handling components are arranged above the base.

[0008] Preferably, the two automatic handling components are fixedly connected to each other on one side thereof, and a workpiece is clamped between the two clamps. A speed reducer housing body is arranged above the blanking plate.

[0009] Preferably, the two clamps are respectively located at the front and rear sides of the workpiece, and the loading plate is located on the left side of the unloading plate.

[0010] Preferably, the lower die seat is fixedly connected to the base, the buffer plate is located between the upper plate and the lower plate, the size of the workpiece is larger than the size of the forming block, and the size of the workpiece is smaller than the size of the buffer plate.

[0011] Preferably, the stamping mechanism includes a hydraulic cylinder, a first hydraulic rod is slidably connected inside the hydraulic cylinder, two second hydraulic rods are slidably connected inside the hydraulic cylinder, an upper die seat is fixedly connected to the bottom of the two second hydraulic rods, a forming groove is provided at the bottom of the upper die seat, a clamping groove is provided on the inner wall of the forming groove, and a pressure plate is clamped inside the clamping groove.

[0012] Preferably, the first hydraulic rod is located between the two second hydraulic rods, the bottom of the first hydraulic rod passes through the top of the upper die seat and extends to the inside of the slot, and the bottom of the first hydraulic rod is clamped with the pressure plate.

[0013] Preferably, the size of the forming groove is larger than the size of the forming block, the upper die seat is located above the buffer plate, the size of the upper die seat is matched with the size of the buffer plate, and the size of the pressing plate is matched with the size of the forming block.

At the same time, when the upper die seat squeezes the buffer plate downward to the limit position, the bottom of the buffer plate abuts against the top of the anti-collision pad, supports and buffers the buffer plate for a second time, and prevents the buffer plate from continuing to move downward under the action of inertia. At the same time, it can also avoid the noise generated by the abutment between the bottom of the buffer plate and the top of the lower die seat and the impact on the device structure. The provision of the air bag can buffer and adapt the air pressure inside the sealing groove to a certain extent when the buffer plate suddenly moves downward, so as to avoid the situation where the air pressure inside the sealing groove changes greatly due to the sudden downward movement of the buffer plate, which affects the internal structure of the lower die seat, and protects the device structure.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figures 2 to 4 As shown, the present invention provides an automatic conveying and stamping device for a precision-cast speed reducer housing, comprising a main body mechanism 2, a buffer mechanism 1 is arranged inside the main body mechanism 2, and a stamping mechanism 3 is arranged above the main body mechanism 2; The buffer mechanism 1 includes a lower die base 101, four sealing grooves 102 are opened inside the lower die base 101, a vent hole 103 is opened inside the lower die base 101, an air bag 104 is fixedly connected inside the vent hole 103, two exhaust holes 105 are opened at the bottom of the lower die base 101, a forming block 106 is fixedly connected to the top of the lower die base 101, the inner wall of the vent hole 103 is elastically connected to the piston rod 108 through a spring 107, a buffer plate 109 is fixedly connected to the top of the piston rod 108, and an anti-collision pad 110 is fixedly connected to the top of the lower die base 101.

[0020] The top of the piston rod 108 passes through the inner wall of the sealing groove 102 and the bottom of the anti-collision pad 110 and extends to the top of the anti-collision pad 110. The vent hole 103 is connected to the four sealing grooves 102. The two exhaust holes 105 pass through the lower mold base 101 and the molding block 106 and extend to the top of the molding block 106. The anti-collision pad 110 is located between the buffer plate 109 and the lower mold base 101, and the molding block 106 is located inside the buffer plate 109. The buffer plate 109 and the molding block 106 are slidingly connected.

[0021] Using the above solution: Figure 1 As shown, Figure 1 The direction close to the icon buffer mechanism 1 is the front, the direction close to the icon speed reducer housing body 207 is the right side, and the direction close to the icon processing part 206 is the left side (through Figure 1 The orientation in the marked illustration is convenient for describing and understanding the positional relationship of the structure). By setting the coordination of the spring 107 and the airbag 104 and other structures, it is convenient to buffer the upper die seat 304 and the buffer plate 109. During the downward stamping process of the upper die seat 304, a downward pressure is applied to the buffer plate 109, so that the buffer plate 109 drives the piston rod 108 downward and squeezes the spring 107, and at the same time compresses the gas inside the sealing groove 102, increases the air pressure inside the sealing groove 102 and the vent hole 103, and buffers the upper die seat 304 and the buffer plate 109 through the elastic force of the spring 107 and the air pressure in the sealing groove 102. The plate 109 is used for buffering to avoid vibration after being pressed, which affects the stamping quality of the forming block 106. At the same time, when the upper die base 304 squeezes the buffer plate 109 to move downward to the limit position, the bottom of the buffer plate 109 abuts against the top of the anti-collision pad 110, supporting and buffering the buffer plate 109 for a second time, preventing the buffer plate 109 from continuing to move downward under the action of inertia, and also avoiding the noise generated by the abutment between the bottom of the buffer plate 109 and the top of the lower die base 101 and the impact on the device structure. The airbag 104 can be set to the dense when the buffer plate 109 suddenly moves downward. The air pressure inside the sealing groove 102 is buffered and adapted to a certain extent, so as to avoid the situation that the air pressure inside the sealing groove 102 changes greatly when the buffer plate 109 moves downward suddenly, and the internal structure of the lower die seat 101 is affected. By setting the exhaust hole 105 and the spring 107 and other structures, it is convenient to push out and unload the speed reducer housing body 207 after molding. When the upper die seat 304 moves upward, the buffer plate 109 will move upward under the action of the elastic force of the spring 107 and the air pressure inside the sealing groove 102, driving the speed reducer housing body 207 after molding to move upward to the molding block 10 6, an exhaust hole 105 is provided above the reducer housing body 207 to balance the air pressure between the reducer housing body 207 and the forming block 106 during the upward movement of the reducer housing body 207, wherein the balanced reducer housing body 207 is a structure after the workpiece 206 is extruded and formed, and when the workpiece 206 is extruded by the upper mold base 304, the workpiece 206 is located above the forming block 106, and the exhaust hole 105 is located below the workpiece 206 at this time, so after the workpiece 206 is extruded into the balanced reducer housing body 207, the balanced reducer housing body 207 is located above the exhaust hole 105.

[0022] like Figure 1As shown, the main mechanism 2 includes a base 201, a loading plate 202 is fixedly connected to the top of the base 201, a unloading plate 203 is fixedly connected to the top of the base 201, two automatic transport components 204 are arranged above the base 201, and the two automatic transport components 204 are fixedly connected to the sides close to each other with clamps 205, a workpiece 206 is clamped between the two clamps 205, and a speed reducer housing body 207 is arranged above the unloading plate 203.

[0023] The two clamps 205 are respectively located on the front and rear sides of the workpiece 206, the loading plate 202 is located on the left side of the lower plate 203, the lower mold base 101 is fixedly connected to the base 201, the buffer plate 109 is located between the loading plate 202 and the lower plate 203, the size of the workpiece 206 is larger than the size of the forming block 106, and the size of the workpiece 206 is smaller than the size of the buffer plate 109.

[0024] Adopt the above scheme: Here is a brief introduction to the structure of the main mechanism 2, describing the structural relationship between the main mechanism 2 and the buffer mechanism 1, and through an external power source, the two automatic transport components 204 are moved towards each other, so that the two clamps 205 clamp the workpiece 206, and the automatic transport component 204 is moved to the right to drive the workpiece 206 to move to the top of the forming block 106, and the stamping work can be started. After the workpiece 206 is stamped and formed, the formed speed reducer housing body 207 can also be unloaded.

[0025] like Figures 1 to 5 As shown, the stamping mechanism 3 includes a hydraulic cylinder 301, a first hydraulic rod 302 is slidably connected inside the hydraulic cylinder 301, two second hydraulic rods 303 are slidably connected inside the hydraulic cylinder 301, the bottoms of the two second hydraulic rods 303 are fixedly connected to an upper die base 304, a forming groove 305 is provided at the bottom of the upper die base 304, a clamping groove 306 is provided on the inner wall of the forming groove 305, a pressing plate 307 is clamped inside the clamping groove 306, the first hydraulic rod 302 is located between the two second hydraulic rods 303, the bottom of the first hydraulic rod 302 passes through the top of the upper die base 304 and extends to the inside of the clamping groove 306, and the bottom of the first hydraulic rod 302 is clamped with the pressing plate 307.

[0026] The size of the forming groove 305 is larger than that of the forming block 106, the upper die seat 304 is located above the buffer plate 109, the size of the upper die seat 304 is adapted to the size of the buffer plate 109, the size of the pressure plate 307 is adapted to the size of the forming block 106, the workpiece 206 is located between the pressure plate 307 and the forming block 106, the size of the pressure plate 307 and the size of the forming block 106 are both adapted to the size of the top of the speed reducer housing body 207.

[0027] The above scheme is adopted: by setting the first hydraulic rod 302 to move downward to fix the pressing plate 307 and the workpiece 206 between the forming block 106 and the pressing plate 307, it can be avoided that when the upper die seat 304 punches the workpiece 206, the position of the workpiece 206 changes, thereby affecting the forming effect of the device; while in the prior art, when the workpiece 206 is punched and formed, the position of the workpiece 206 is easily offset during the deformation or movement process, and when the workpiece 206 is punched, it is easy to cause the device to vibrate due to the impact force, thereby affecting the forming effect of the device and reducing the production quality; however, the exhaust hole 105 is provided in the technical scheme to balance the speed reducer housing body 207 during the upward movement of the speed reducer housing body 20 7 and the forming block 106. At the same time, before punching the workpiece 206, the first hydraulic rod 302 is first used to move the pressing plate 307 downward to fix the workpiece 206 between the forming block 106 and the pressing plate 307. This can prevent the position of the workpiece 206 from changing when the upper die seat 304 punches the workpiece 206, thereby affecting the forming effect of the device. At the same time, the cooperation of structures such as the buffer plate 109 and the airbag 104 is provided to facilitate buffering of the workpiece 206 during punching. The provision of the airbag 104 can also prevent the internal air pressure of the sealing groove 102 from changing greatly when the buffer plate 109 suddenly moves downward, thereby affecting the internal structure of the lower die seat 101, thereby protecting the device structure.

[0028] The working principle and use process of the present invention are as follows: first, the workpiece 206 is moved to the top of the loading plate 202 by the loading device, and then the two automatic handling components 204 are moved in a direction close to each other by an external power source, so that the two clamps 205 clamp the workpiece 206, and after the workpiece 206 is moved to the top of the forming block 106 by the automatic handling component 204 moving to the right, the automatic handling component 204 drives the clamps 205 to move away from each other to release the clamps of the workpiece 206. The first hydraulic rod 302 is then driven downward by the hydraulic cylinder 301 to drive the bottom of the pressing plate 307 to abut against the top of the workpiece 206, and the workpiece 206 is fixed between the forming block 106 and the pressing plate 307. The second hydraulic rod 303 is then driven downward by the hydraulic cylinder 301 to drive the upper die holder 304 to make the bottom of the upper die holder 304 press downward the part of the workpiece 206 that is larger than the forming block 106, and the workpiece 206 is shaped by the cooperation of the forming groove 305 and the forming block 106. During the downward stamping process of the upper die holder 304, downward pressure is applied to the buffer plate 109, so that the buffer plate 109 drives the piston rod 108 downward and squeezes the spring 107, and at the same time compresses the gas inside the sealing groove 102, increases the air pressure inside the sealing groove 102 and the vent hole 103, and buffers the buffer plate 109 through the elastic force of the spring 107 and the air pressure in the sealing groove 102. At the same time, when the upper die holder 304 squeezes the buffer plate 109 downward to the limit position, the bottom of the buffer plate 109 abuts against the top of the anti-collision pad 110, supporting and buffering the buffer plate 109. The airbag 104 can provide a certain buffering and adaptation effect on the air pressure inside the sealing groove 102 when the buffer plate 109 suddenly moves downward. After the workpiece 206 is punched into the speed reducer housing body 207 through the forming groove 305 and the forming block 106, the first hydraulic rod 302 and the second hydraulic rod 303 are used to drive the pressure plate 307 and the upper die seat 304 upward respectively through the hydraulic cylinder 301. At this time, the buffer plate 109 will move upward under the action of the elastic force of the spring 107 and the internal air pressure of the sealing groove 102, driving the formed speed reducer housing body 207 to move upward to the top of the forming block 106. The exhaust hole 105 is set to balance the air pressure between the speed reducer housing body 207 and the forming block 106 during the upward movement of the speed reducer housing body 207. Finally, the automatic handling component 204 is used to enable the clamp 205 to clamp the speed reducer housing body 207 and move it to the top of the blanking plate 203.
