Description

Technical Field

[0001] The invention relates to the technical field of casting processing, and in particular to a double-station casting punching device and a use method thereof. Background Art

[0002] Castings are metal shaped objects obtained by various casting methods. During the production and processing of castings, they need to be punched for subsequent use.

[0003] At present, before drilling holes in the formed casting, the casting needs to be positioned to prevent displacement of the casting during the drilling process to ensure that the position of the punched hole is accurate.

[0030] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] In the present invention, by means of the provided limiting mechanism, after the casting to be punched is set on the clamping base plate, the two auxiliary support blocks are used to support the casting, and then the side of the casting is limited by adjusting the position of the positioning slide plate. At the same time, under the limiting action of the first locking pressure plate and the second locking pressure plate, the casting can be prevented from being separated from the two auxiliary support blocks, thereby achieving a good limiting effect. After that, after the guide hole drill sleeve is installed on the punching auxiliary guide, the casting can be punched. In this way, in actual use, two castings installed on the clamping base plate can be punched at the same time, thereby improving the punching efficiency.

[0033] In the present invention, the locking mechanism is provided, and after the casting is limited, the two rotating shafts can be rotated. When the rotating shafts rotate, the corresponding swing arms can be driven to rotate. At this time, under the transmission cooperation of the blocking shaft, the corresponding ejector assembly can be driven to move, so that the ejector assembly can be used to press the casting;

[0034] In the present invention, by means of the positioning mechanism, when the stepping motor is started to drive the clamping substrate to rotate 180°, the positioning ring can be driven to rotate synchronously through the support shaft. After the clamping substrate is adjusted, the transmission component can be started to drive the two U-shaped clamping plates to move, so that the positioning protrusion is clamped with one of the U-shaped clamping plates, thereby braking the positioning ring. At the same time, by braking the positioning ring, the clamping substrate can be positioned through the support shaft.

[0035] In the present invention, by means of the collection mechanism, after the drilling of the casting is completed, the casting can be turned over to the bottom of the clamping base, and the waste chips can fall into the collection box through the base, thereby preventing a large amount of waste chips from adhering to the clamping base, and reducing the frequency of cleaning the waste chips. When the collected waste chips need to be cleaned, the push plate can be pushed downward to move the plug plate downward and disengage from the plug ring, and then the movable box can be pulled to one side of the base, and then the two handles can be lifted upward to move the collection box out of the movable box, so that the collected waste chips can be conveniently cleaned.

[0036] The present invention can achieve pressing and positioning of two castings at one time, so that when drilling holes in the castings, the two castings can be drilled at the same time, thereby improving work efficiency, and after the drilling of the castings is completed, the castings can be turned over so that waste chips can fall into the collection box, which can facilitate the cleaning of the waste chips. Therefore, it has good convenience in actual use. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The embodiments of the present invention are described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0049] In the description of the embodiments of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms, "connection" and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "connection" can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed" means that they are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present invention, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present invention.

[0050] Example 1: Reference Figure 1-Figure 9 A double-station casting punching device of this embodiment includes a base 1, on both sides of the top of which a first support plate 2 and a second support plate 3 are fixedly installed. A stepper motor 4 is fixedly installed on the top of one side of the first support plate 2. The output shaft of the stepper motor 4 passes through the first support plate 2 and is fixedly connected to a clamping base plate 6. At the same time, a support shaft 5 is rotatably connected to the second support plate 3, and one end of the support shaft 5 is fixedly connected to one side of the clamping base plate 6, thereby ensuring that the clamping base plate 6 can rotate under the drive of the stepper motor 4.

[0051] like Figure 5 As shown, two punching auxiliary guides 62 are symmetrically installed on the top and bottom of the clamping base plate 6 for guiding the punching tool during the punching process. In order to stably clamp the casting, two limiting mechanisms are also provided on the top and bottom of the clamping base plate 6. Each limiting mechanism includes two guide rails 9 fixed on the clamping base plate 6, and a positioning slide 10 is slidably connected to the guide rail 9. By adjusting the position of the positioning slide 10, the side of the casting can be limited. In addition, the first locking pressure plate 7 and the second locking pressure plate 8 are respectively installed on the clamping base plate 6, both of which are used to press and limit the casting. At the same time, two auxiliary support blocks 61 are also fixedly installed on the clamping base plate 6 for supporting the casting.

[0052] like Figure 6As shown, in order to realize the locking function, the device is also provided with a locking mechanism. The mechanism includes a fixed plate 15 fixed on one side of the clamping substrate 6, and two rotating shafts 16 are symmetrically penetrated and rotatably connected on the fixed plate 15. The top and bottom ends of the rotating shaft 16 are fixedly installed with swing arms 17, and one side of the swing arm 17 is fixedly installed with a stopper shaft 18. The top and bottom of the clamping substrate 6 are installed with ejector assemblies, and each ejector assembly includes two positioning plates 11, and the positioning plate 11 is penetrated and slidably connected with a positioning pin 12. One end of the positioning pin 12 is used to press and limit the casting, and the other end is connected to the stopper shaft 18 through the connecting plate 13 and the transmission plate 14. Two transmission holes 19 are symmetrically provided on the transmission plate 14, and one end of the stopper shaft 18 extends into the corresponding transmission hole 19 to realize transmission matching. When the rotating shaft 16 is rotated, the swing arm 17 and the stopper shaft 18 move accordingly, and the transmission plate 14 and the positioning pin 12 are driven to move through the transmission hole 19, thereby pressing the casting.

[0053] like Figure 6 As shown, in order to maintain the locked state, a hook assembly is also provided. The assembly includes a mounting shaft 21 fixed to one side of the clamping base plate 6, and a lock buckle 22 is rotatably sleeved on the mounting shaft 21, and the lock buckle 22 is clamped with the corresponding clamping rod 20. Two torsion springs 23 are also sleeved on the mounting shaft 21, which are respectively located above and below the lock buckle 22, and the two ends of the torsion spring 23 are respectively fixedly connected to one end of the mounting shaft 21 and one side of the lock buckle 22. After the casting is pressed by the positioning pin 12, the lock buckle 22 is released, and the elastic potential energy of the torsion spring 23 drives the lock buckle 22 to rotate, so that it is clamped with the corresponding clamping rod 20, thereby locking the position of the swing arm 17 and maintaining the stable pressing of the positioning pin 12 on the casting.

[0054] like Figure 7 As shown, in order to position and brake the support shaft 5, a positioning mechanism is installed on one side of the second support plate 3, and the positioning mechanism is connected to the support shaft 5 to keep the support shaft 5 stable during the punching process. At the same time, in order to collect the waste generated during the punching, a collection mechanism is also installed at the bottom of the base 1 to ensure a clean working environment.

[0055] like Figure 7 As shown, the positioning mechanism mainly includes a positioning ring 24, a positioning protrusion 25, a support assembly and a transmission assembly. The positioning ring 24 is fixedly sleeved on the support shaft 5, and a positioning protrusion 25 is arranged on it. The support assembly is installed on one side of the second support plate 3, and includes two symmetrically installed support rails 26, and one end of the support rail 26 is fixedly connected to the mounting rod 29. Two U-shaped clamping plates 27 are respectively slidably connected in the two support rails 26, and are used for movable clamping with the positioning protrusion 25.

[0056] The transmission assembly is connected to the support assembly, and the transmission assembly includes a rectangular ring 30 fixedly mounted on the bottom of the moving plate 28, an electric push rod 32 is installed at the bottom of the rectangular ring 30, the output shaft of the electric push rod 32 is connected to the linkage plate 31, the two sides of the linkage plate 31 are rotatably connected to the rotating rod 33, and the bottom end of the rotating rod 33 is rotatably connected to the second support plate 3. After the stepper motor 4 is started to drive the clamping substrate 6 to rotate 180°, the electric push rod 32 is started to make the linkage plate 31 slide longitudinally, drive the rotating rod 33 to rotate, and then drive the U-shaped clamping plate 27 to move horizontally through the moving plate 28 and the two fixed rods until the positioning protrusion 25 is clamped with one of the U-shaped clamping plates 27, so as to achieve the braking and positioning of the positioning ring 24 and the clamping substrate 6.

[0057] The support assembly provides sliding support for the U-shaped card plate 27 through the support rail 26, and the fixed rod connects the U-shaped card plate 27 with the movable plate 28. When the electric push rod 32 in the transmission assembly works, it pushes the linkage plate 31 to slide in the rectangular ring 30. Through the lever action of the rotating rod 33, the movable plate 28 moves horizontally on the support rail 26, thereby driving the U-shaped card plate 27 to move, thereby realizing the clamping or separation with the positioning protrusion 25.

[0058] The transmission assembly drives the linkage plate 31 to slide up and down in the rectangular ring 30 through the telescopic movement of the electric push rod 32, and the rotating rods 33 rotatably connected on both sides of the linkage plate 31 rotate with the movement of the linkage plate 31, thereby driving the moving plate 28 to move on the support rail 26. This design utilizes the lever principle and realizes remote control of the U-shaped card plate 27 through a simple mechanical structure.

[0059] Example 2: Figure 8 and Fig. 9 As shown, the collecting mechanism includes a support leg 34, a supporting ring 35, a limiting ring 36, a limiting slide 37, a movable box 38, a supporting ring 45, a collecting box 46 and other components. The support leg 34 is fixed to the bottom of the base 1, the supporting ring 35 and the limiting ring 36 are fixed on the support leg 34 to provide support and guidance for the movable box 38. The movable box 38 slides under the base 1 through the slide bar 44 and the support rail 43, and a supporting ring 45 and a collecting box 46 are installed inside.

[0060] The collection box 46 is easy to take out and clean through the placement ring 47 and the handle 48. The plug plate 40 in the limit frame 39 is clamped with the plug ring 41 on one side of the base 1, and the plug plate 40 is kept locked by the compression spring 42. When it is necessary to clean the waste, push the push plate 49 downward to make the plug plate 40 separate from the plug ring 41, then pull the movable box 38 to the side of the base 1, and take out the collection box 46 through the handle 48 for cleaning.

[0061] The present invention provides a method for using a double-station casting punching device, comprising the following steps:

[0062] S1, placing two castings above and below the clamping base plate 6, and using two auxiliary support blocks 61 to support the castings;

[0063] S2. Adjust the position of the positioning slide plate 10 to limit the side of the casting. At the same time, under the limiting action of the first locking plate 7 and the second locking plate 8, the casting can be prevented from being separated from the two auxiliary support blocks 61;

[0064] S3, rotating the two rotating shafts 16, when the rotating shafts 16 rotate, the corresponding swing arms 17 can be driven to rotate, when the blocking shaft 18 moves in an arc shape along with the swing arms 17, under the transmission cooperation with the transmission hole 19, the transmission plate 14 can be driven to move laterally, so that the positioning pins 12 can be driven to move through the connecting plate 13, so that the casting can be pressed and limited by the positioning pins 12;

[0065] S4. When the swing arm 17 is rotated, the clamping rod 20 can be driven to move synchronously. After the casting is pressed by the positioning pin 12, the lock buckle 22 can be released. The two torsion springs 23 in a stressed state can use their elastic potential energy to drive the lock buckle 22 to rotate, so that the lock buckle 22 and the corresponding clamping rod 20 are clamped together, so that the swing arm 17 can be braked;

[0066] S5, start the electric push rod 32 to drive the linkage plate 31 to slide longitudinally along the rectangular ring 30, which can drive the two rotating rods 33 to rotate. When the rotating rod 33 rotates upward, it can drive the linkage plate 31 to move upward in an arc shape, that is, it can drive the rectangular ring 30 to approach the second support plate 3, thereby driving the moving plate 28 to move, and thus driving the two U-shaped card plates 27 to move horizontally. At this time, under the cooperation of the sliding support of the two support rails 26, the U-shaped card plates 27 can be kept to move horizontally, so that the corresponding U-shaped card plates 27 can be positioned and clamped with the positioning protrusions 25;

[0067] S6. After the guide hole drill sleeve is installed on the drilling auxiliary guide 62, the casting can be drilled. In actual use, two castings installed on the clamping substrate 6 can be drilled at the same time, thereby improving the drilling efficiency;

[0068] S7, start the electric push rod 32 to retract its output shaft, so that the U-shaped clamping plate 27 can be separated from the positioning protrusion 25 through reverse transmission of the structure;

[0069] S8, starting the stepper motor 4 to drive the clamping substrate 6 to rotate 180 degrees, and the waste chips above the clamping substrate 6 can fall into the collection box 46;

[0070] S9. When the collected waste needs to be cleaned, the push plate 49 can be pushed downward to move the plug plate 40 downward and disengage from the plug ring 41. Then the movable box 38 can be pulled to one side of the base 1. Then the two handles 48 can be lifted upward to move the collection box 46 out of the movable box 38, so that the collected waste can be cleaned conveniently.

[0071] However, as is well known to those skilled in the art, the working principles and wiring methods of the stepper motor 4 and the electric push rod 32 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0072] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention; the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
