Description

Technical Field

[0001] The invention relates to the field of water pump production, and in particular to an automated device for bending a buckle assembly of a water pump. Background Art

[0002] As an important component of the water pump, the water pump buckle assembly has high requirements for shape and size accuracy.

[0003] At present, the bent parts of the buckle assembly need to be placed in the fixture manually, and one part can be produced only after completing the part placement, which results in low production efficiency.

[0004] In addition, the positioning of buckle components often relies on manual operation, which not only increases the difficulty of operation, but also makes it difficult to ensure the accuracy of positioning, resulting in inconsistent quality of parts and insufficient positioning accuracy during the production process.

[0005] Moreover, the existing working environment is not clean enough, the overall height of the existing device is low, and the operator needs to sit on a low bench and bend over to operate. Working for a long time can easily lead to fatigue, and the device lacks installation protection devices. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and to provide an automated equipment for bending a water pump buckle assembly. The automated equipment and a bending mold are used for manufacturing, which can ensure that the bending angle and shape of the assembly meet the design requirements, while improving production efficiency and product quality, reducing labor intensity, and improving the working environment.

[0007] The object of the present invention is to achieve the following technical solution: an automated device for bending a water pump buckle assembly, wherein the water pump buckle assembly includes a drawstring and a buckle body, and the device includes:

[0008] A frame, on which a placing platform is provided for loading the water pump buckle assembly, and a discharge port is provided on one side of the frame for unloading the water pump buckle assembly;

[0009] The cylinder is fixed on the frame through the cylinder mounting plate, and the piston rod of the cylinder is used to connect and drive the pressure rod;

[0010] A rotating disc assembly is arranged on a frame below the cylinder and faces the placement platform. A plurality of workstations are evenly arranged on the rotating disc assembly along the circumferential direction. A forming mold is arranged on each workstation. The water pump buckle assembly is pre-placed and positioned on the forming mold. When the rotating disc assembly rotates, the forming molds on each workstation pass under the pressure rod one by one. The pressure rod cooperates with the forming mold to press-fit the water pump buckle assembly.

[0011] A material unloading mechanism is arranged on a frame between the rotating disk assembly and the discharge port, and is used to grab the water pump buckle assembly press-fitted on the forming mold and transport it to the discharge port to complete unloading; and

[0012] The touch screen system is fixed on the cylinder mounting plate and is used to electrically connect to the electrical control box. The electrical control box is installed on the frame below the rotating disk assembly, and the electrical control box is electrically connected to the cylinder, the rotating disk assembly and the unloading mechanism to realize control.

[0013] As a further technical solution, the rotating disk assembly includes a turntable arranged below the cylinder, and a cam divider is arranged below the turntable for driving the turntable to rotate. The cam disk is installed on the output shaft of the cam divider, and a photoelectric switch is arranged opposite to the cam disk; when the input shaft of the cam divider rotates one circle, the cam disk rotates one circle synchronously. At this time, the photoelectric switch is triggered and sends a signal to the electrical control box to control the cam divider to stop running. At the same time, the cylinder presses down and the pressure rod presses the part into the molding mold for molding.

[0014] As a further technical solution, the turntable is sequentially provided with four workstations, namely, a part forming position, a waiting position, a loading operation position and a waiting position for bending; the part forming position is located directly below the pressure rod of the cylinder for press-fitting and forming of the water pump buckle assembly; the waiting position is located directly below the unloading mechanism, and the unloading mechanism clamps the water pump buckle assembly on the waiting position and unloads it to the discharge port; the loading operation position faces the placement platform, and the loading is operated by the operator.

[0016] As a further technical solution, a U-shaped groove is opened on the bending die, and a molding groove is provided in the center of the U-shaped groove for press-fitting the water pump buckle assembly. A center hole A is opened in the center of the molding groove for the positioning pin to pass through, and threaded holes are opened at the bottom of the U-shaped groove on both sides of the molding groove for connecting shoulder bolts.

[0017] As a further technical solution, the upper end of the clamping block is a hook-shaped structure, and a drawstring positioning groove B is opened on the surface of the upper end, and a drawstring positioning groove A is opened at the position corresponding to the drawstring positioning groove B on the top of the mold base. When the side wall of the clamping block is against the groove, the upper end surface is flush with the top of the mold base, and the drawstring is placed in the drawstring positioning groove A and the drawstring positioning groove B to achieve positioning; a vertical groove is opened in the vertical direction at the center of the pressure rod, and horizontal grooves are opened on both sides of the pressure rod in the horizontal direction. When the water pump buckle assembly is pressed into the bending mold, the drawstring is inserted into the vertical groove, thereby reducing the bending angle to achieve material rebound compensation. At the same time, the upper end of the clamping block is inserted into the horizontal groove, and the clamping block applies pressure to the water pump buckle assembly to ensure secondary molding of the material. A cylindrical hole connected to the vertical groove is opened in the center of the pressure rod for the positioning pin to pass through.

[0018] As a further technical solution, the stretch spring is tightened and fixed by screws through a screw hole A opened on the die base and a screw hole B opened on the clamping block. The distance between the screw hole A and the screw hole B is greater than the center distance of the hook circle of the stretch spring, so that the stretch spring maintains a certain stretching state, ensuring that the die base and the clamping block maintain a state of mutual fit; the contact position between the die base and the bottom of the clamping block adopts a rounded structure, so that the clamping block rotates around the axis of the rounded structure.

[0019] As a further technical solution, a safety grating is installed at the opening of the frame facing the placement platform, and the safety grating is electrically connected and communicated with the touch screen system; an oil-water separator is installed on the frame.

[0020] As a further technical solution, guide columns are provided on both sides of the cylinder, and the guide columns are slidably guided by guide sleeves correspondingly installed on the cylinder mounting plate. The lower end of the guide column is fixed on the cylinder push plate. The piston rod of the cylinder is connected to drive the cylinder push plate through a floating joint, and a pressure rod is fixedly connected under the cylinder push plate; the cylinder realizes the adjustment of the downward stroke through the cylinder limit sleeve.

[0049] Reference Fig.15 , 16 The water pump buckle assembly includes a drawstring 10 and a buckle body 11, and a center hole B11-1 is opened in the center of the buckle body 11.

[0050] like Figure 1 As shown, a placement platform 213 is provided on the frame 21, and the operator loads the water pump buckle assembly through the placement platform 213. A discharge port 212 is provided on one side of the frame 21, and the water pump buckle assembly is unloaded through the discharge port 212. A safety grating 22 is installed at the opening of the frame 21 facing the side of the placement platform 213. The safety grating 22 is electrically connected to the touch screen system 24 for communication, so that when the operator enters the safe range during the operation of the equipment, an alarm signal is triggered, and the equipment is controlled to stop running to ensure the safety of the personnel. Preferably, an oil-water separator 23 is installed on the frame 21, and the oil-water separator 23 can filter the moisture and grease in the compressed air entering the equipment from the outside, thereby extending the operating life of the cylinder.

[0052] like Figure 1 , 4 As shown in Figure 5, the rotating disk assembly 210 is arranged on the frame 21 below the cylinder 25 and faces the placement platform 213. A number of workstations (four in this embodiment, or other numbers) are evenly arranged on the rotating disk assembly 210 along the circumferential direction. A molding die 210-3 is arranged on each workstation. The water pump buckle assembly is pre-placed and positioned on the molding die 210-3. When the rotating disk assembly 210 rotates, the molding die 210-3 on each workstation passes under the pressure rod 1 one by one, and the water pump buckle assembly is press-fitted and formed through the cooperation between the pressure rod 1 and the molding die 210-3.

[0053] Further, such as Figure 4 , 5 As shown, the rotating disk assembly 210 includes a rotating disk 210-2 arranged below the cylinder 25, and a cam divider 210-1 is arranged below the rotating disk 210-2. The cam divider 210-1 can drive the rotating disk 210-2 to rotate. A cam disk 210-4 is installed on the output shaft of the cam divider 210-1, and a photoelectric switch 210-5 is arranged opposite to the cam disk 210-4. When the input shaft of the cam divider 210-1 rotates one circle, the cam disk 210-4 rotates one circle synchronously. At this time, the photoelectric switch 210-5 senses the trigger and sends a signal to the electrical control box 29, controlling the cam divider 210-1 to stop running. At the same time, the cylinder 25 presses down and the pressure rod 1 presses the part into the bending mold 5 of the molding mold 210-3 for molding. The cam divider 210-1 is threadedly connected and fixed to the frame 21 through the divider fixing plate 210-6.

[0054] Reference Figure 1 , 6, a total of four stations are arranged on the turntable 210-2, including the part forming position I, the waiting position II, the loading operation position III and the waiting bending position IV, and each station is 90° apart. Among them, the part forming position I is located directly below the pressure rod 1 of the cylinder 25, and can be used for press-fitting and molding of the water pump buckle assembly. The waiting position II is located directly below the unloading mechanism 211, and the unloading mechanism 211 clamps the water pump buckle assembly on the waiting position II and transports it to the discharge port 212 for unloading. The loading operation position III faces (is opposite to) the placement platform 213, which is convenient for the operator to operate the loading. The waiting bending position IV is a transfer station, which is set between the part forming position I and the loading operation position III. After easy operation, enter the waiting bending position IV to wait, and then rotate the turntable 210-2 to enter the part forming position I for press-fitting and molding.

[0055] like Figures 8 to 11 As shown, the molding die 210-3 includes a die base 2 fixed on the turntable 210-2, a groove 2-6 is provided in the center of the die base 2, two symmetrical clamping blocks 3 are placed in the groove 2-6, the side walls 3-5 of the clamping blocks 3 lean against the groove 2-6, and the die base 2 and the corresponding clamping blocks 3 are connected by a tension spring 6, so that the die base 2 and the clamping blocks 3 are kept in a constant fit state. Fig.13 As shown, a positioning pin hole 2-3 is provided at the bottom of the groove 2-6 for fixing the positioning pin 4. A fixing hole 2-2 is provided at the bottom of the groove 2-6 on both sides of the positioning pin hole 2-3. The fixing hole 2-2 is used to install the shoulder bolt 8. The shoulder bolt 8 is sleeved with a compression spring 9 and connected to the bottom of the bending die 5, so that the bottom surface of the bending die 5 contacts the clamping block 3, and the bending die 5 is inserted into the openings 3-7 of the two clamping blocks 3. The positioning pin 4 passes through the two clamping blocks 3 and then penetrates the bending die 5, and extends from the top of the bending die 5 (as shown in FIG. 1 ). Figure 8 , 9 As shown), the positioning pin 4 can cooperate with the center hole B11-1 opened on the buckle body 11 to position the water pump buckle assembly.

[0056] Reference Fig.17 A U-shaped groove 5-4 is opened on the bending mold 5, and a molding groove 5-3 is provided in the center of the U-shaped groove 5-4. The water supply pump buckle assembly is press-fitted. A center hole A5-1 is opened in the center of the molding groove 5-3 for the positioning pin 4 to pass through. Threaded holes 5-2 are opened at the bottom of the U-shaped groove 5-4 on both sides of the molding groove 5-3, which can be connected to the shoulder bolts 8.

[0057] like Fig.13 , 14As shown, the upper end portion 3-6 of the clamping block 3 is a hook-shaped structure, a drawstring positioning groove B3-1 is provided on the surface of the upper end portion 3-6, and a drawstring positioning groove A2-1 is provided at the top of the mold base 2 at a position corresponding to the drawstring positioning groove B3-1. When the side wall 3-5 of the clamping block 3 is against the groove 2-6, the surface of the upper end portion 3-6 is flush with the top of the mold base 2 (as shown in FIG. Figure 8 , 10 As shown), the drawstring 10 is placed into the drawstring positioning groove A2-1 and the drawstring positioning groove B3-1 to achieve positioning. Fig.12 A vertical groove 1-1 is formed in the center of the pressure rod 1 in the vertical direction, and horizontal grooves 1-2 are formed in the horizontal direction on both sides of the pressure rod 1. When the water pump buckle assembly is pressed into the bending die 5, the drawstring 10 is inserted into the vertical groove 1-1, thereby reducing the bending angle to achieve the rebound compensation of the material. At the same time, the upper end 3-6 of the clamping block 3 is inserted into the horizontal groove 1-2, and the clamping block 3 applies pressure to the water pump buckle assembly to ensure the secondary molding of the material. A cylindrical hole 1-3 connected to the vertical groove 1-1 is formed in the center of the pressure rod 1 for the positioning pin 4 to penetrate.

[0058] Reference Fig.10 , 11 , 13, 14, the tension spring 6 is tightened and fixed by the screw hole A2-5 opened on the die base 2 and the screw hole B3-3 opened on the clamping block 3 through the screw 7. Preferably, the distance between the screw hole A2-5 and the screw hole B3-3 is greater than the center distance of the hook circle of the tension spring 6, so that the tension spring 6 maintains a certain tension state, ensuring that the die base 2 and the clamping block 3 maintain a state of mutual contact. The contact position between the die base 2 and the bottom of the clamping block 3 adopts a rounded structure, so that the clamping block 3 rotates around the axis of the rounded structure. Further, as Fig.13 As shown, notches 2-4 are provided on both sides of the mold base 2 to facilitate fixing the mold base 2 on the rotating disk 210-2 by bolts. Fig.14 As shown, the lower end of the clamping block 3 is provided with an avoidance hole 3-2, which can avoid the compression spring 9 and prevent interference. The clamping block 3 is also provided with a screw hole C3-4 for installing a screw 7, which plays a role in positioning the clamping block 3 in the die base 2 to prevent position deviation. At the same time, the screw hole C3-4 is provided on the surface on the same side as the screw hole B3-3 and is close to the lower end of the clamping block 3.

[0059] like Figure 1 , 3As shown, the unloading mechanism 211 is arranged on the frame 21 between the rotating disk assembly 210 and the discharge port 212. The unloading mechanism 211 is used to grab the water pump buckle assembly pressed and formed on the forming mold 210-3, and transport it to the discharge port 212 to complete unloading. Further, the unloading mechanism 211 includes a three-axis cylinder 211-1, a slide cylinder 211-2 and a guide rod cylinder 211-4, wherein the slide cylinder 211-2 is installed on the frame 21 through a slide fixing plate 211-5, and the three-axis cylinder 211-1 is installed on the slide of the slide cylinder 211-2, and slides laterally along the slide cylinder 211-2 to achieve movement between the forming mold 210-3 and the discharge port 212. The guide rod cylinder 211-4 is connected to the push plate of the three-axis cylinder 211-1 through the guide rod cylinder mounting plate 211-3. The three-axis cylinder 211-1 drives the guide rod cylinder 211-4 to move up and down in the vertical direction, and the guide rod cylinder 211-4 is used to clamp the water pump buckle assembly.

[0060] Reference Figure 1 , 7 The touch screen system 24 is fixed on the cylinder mounting plate 28, and the touch screen system 24 is electrically connected to the electrical control box 29. The electrical control box 29 is installed on the frame 21 below the rotating disk assembly 210, and the electrical control box 29 is electrically connected to the cylinder 25, the rotating disk assembly 210 and the unloading mechanism 211 to realize signal control.

[0061] Working process of the present invention:

[0062] When working, the touch screen system 24 is used to set parameters first, and the electrical control box 29 supplies power to the entire system and equipment. The operator loads the water pump buckle assembly on the platform 213 from the loading operation position III, positions the drawstring 10 through the drawstring positioning groove A2-1 and the drawstring positioning groove B3-1, and positions the buckle body 11 through the center hole B11-1 and the positioning pin 4. After pre-positioning, Fig.10 As shown, at this time, the pressure rod 1 has not been pressed down.

[0063] Start the cylinder 25, which provides downward pressure for the bending of the parts. The cylinder 25 is installed on the cylinder mounting plate 28. The cylinder head is equipped with a floating joint 25-3, which can compensate for the concentricity deviation of the vertical movement of the cylinder 25. The floating joint 25-3 is also connected to the cylinder push plate 25-4. Guide columns 25-1 are installed on both sides of the cylinder push plate 25-4. The guide columns 25-1 slide up and down in cooperation with the bearing (guide sleeve 25-2) installed on the cylinder mounting plate 28 to ensure the axial accuracy of the cylinder 25's upward and downward movement. At the same time, a pressure rod 1 is installed at the bottom of the cylinder push plate 25-4, and the pressure rod 1 presses the parts into the bending mold 5 for molding. The cylinder limit sleeve 25-5 is installed on the cylinder shaft and can be used to adjust the downward stroke of the cylinder 25.

[0064] like Figure 6 As shown, the turntable 210-2 is provided with a part forming position I, a waiting position II, a loading operation position III and a waiting bending position IV in sequence, a total of four stations, each station is 90° apart. Among them, the part forming position I is located directly below the pressure rod 1 of the cylinder 25, and can be used for press-fitting and forming of the water pump buckle assembly. The waiting position II is located directly below the unloading mechanism 211, and the unloading mechanism 211 clamps the water pump buckle assembly on the waiting position II and transports it to the discharge port 212 for unloading. The loading operation position III faces (is opposite to) the placement platform 213, which is convenient for the operator to operate the loading. The waiting bending position IV is a transfer station, which is set between the part forming position I and the loading operation position III. After the operation is easy to operate, first enter the waiting bending position IV to wait, and then the turntable 210-2 rotates to enter the part forming position I for press-fitting and forming.

[0065] And when the input shaft of the cam divider 210-1 rotates one circle, the cam disc 210-4 rotates one circle synchronously. At this time, the photoelectric switch 210-5 senses the trigger and sends a signal to the electrical control box 29, controlling the cam divider 210-1 to stop running. At the same time, the cylinder 25 presses down and the pressure rod 1 presses the part into the bending mold 5 of the forming mold 210-3 for forming (the structure of the cam disc 210-4 is determined by the performance parameters of the selected cam divider 210-1). The turntable 210-2 rotates 90° each time under the control of the cam divider 210-1, and after each rotation of 90°, at the part forming position I, the cylinder 25 controls the pressure rod 1 to press down to complete the press-fitting of a set of water pump buckle components. When the part completes one bending forming, the cam divider 210-1 performs the next station conversion. At this time, the part after bending forming is transferred to the waiting position II (close to the unloading mechanism 211). At the same time, the three-axis cylinder 211-1 moves down, and the guide rod cylinder 211-4 clamps the bent part. After the three-axis cylinder 211-1 moves up to the specified position, the slide cylinder 211-2 moves to the discharge port 212. After reaching the specified position, the guide rod cylinder 211-4 releases the bent part, and the part falls into the material frame.

[0066] At the waiting position II, the water pump buckle assembly formed by press-fitting at the previous station is clamped by the unloading mechanism 211, and unloaded from the discharge port 212. At the loading operation position III, the operator completes the loading, and the waiting bending position IV serves as a waiting station.

[0067] Since the safety grating 22 is installed on both sides of the frame 21, when a person enters the safe range during the operation of the equipment, an alarm signal can be triggered, and the equipment can be stopped to ensure the safety of the personnel.

[0068] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and inventive concept of the present invention should fall within the protection scope of the claims attached to the present invention.
