Description

Technical Field

[0001] This utility model relates to the field of positioning technology for casting processing, specifically a positioning device for metal casting processing. Background Technology

[0002] Castings are metal shaped objects obtained by various casting methods. They are objects with a certain shape, size and properties obtained by pouring, injecting, sucking or other casting methods into a pre-prepared mold after smelting liquid metal, cooling and then grinding.

[0003] In the field of metal casting processing, the positioning of castings is a crucial step in ensuring machining accuracy and efficiency. Casting processing often requires the treatment of multiple surfaces. Traditional equipment, after completing the machining of one surface, requires manual disassembly of the casting and readjustment of its angle and position. This is not only cumbersome and time-consuming, but also prone to errors due to repeated positioning, reducing machining accuracy. When there is machining demand on the clamped part of the casting, the clamps may obstruct the machining, creating blind spots that cannot be fully processed. This necessitates additional steps to remove these blind spots, further reducing production efficiency.

[0004] Therefore, we propose a positioning device for metal casting processing to solve the problems mentioned above. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model:

[0006] The purpose of this utility model is to provide a positioning device for metal casting processing, so as to solve the problems currently in the market mentioned in the background art.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, the present invention provides the following technical solution: a positioning device for metal casting processing, comprising a frame, a platform fixedly installed on the upper end of the frame, a bearing member rotatably installed on the upper middle part of the platform, a rotating plate sleeved on the outer side of the bearing member, the rotating plate rotatably installed on the platform, and a clamping device installed on the rotating plate;

[0009] A toothed ring one is fixedly installed on the inner side of the lower end of the rotating plate, and a toothed ring two is installed on the outer side of the lower part of the bearing member. A drive module is installed between the rotating plate and the bearing member. The drive module includes a drive member and an adjustment member installed on the platform. A transmission member is installed between the output end of the drive member and the output end of the adjustment member. The drive module drives the rotating plate and the bearing member to rotate respectively through cooperation with toothed ring one and toothed ring two.

[0010] Furthermore, the clamp includes two electric push rods, which are symmetrically distributed about the center of the carrier, and the output end of the electric push rod is equipped with a clamping plate.

[0011] The above technical solution enables the electric push rod to move the clamping plate close to the casting and clamp and fix the casting after it is started.

[0012] Furthermore, the support component includes a rotating cylinder mounted on the platform via bearings, an electric push rod II is fixedly installed inside the rotating cylinder, and a support plate is installed at the output end of the electric push rod II, and the toothed ring II is sleeved and fixed on the lower outer side of the rotating cylinder.

[0013] The above technical solution enables the electric push rod two to move the load-bearing plate up and down after it is started.

[0014] Furthermore, the driving component includes a motor mounted on the platform, the output shaft of the motor is connected to a rotating shaft, and the upper end of the rotating shaft is fixedly connected to a drive shaft in a quincunx shape.

[0015] The above technical solution enables the drive shaft to rotate via the rotating shaft after the motor starts.

[0016] Furthermore, the adjusting component includes an electric push rod three fixedly mounted on the platform, and a movable plate is installed at the output end of the electric push rod three.

[0017] The above technical solution enables the movable plate to move up and down when the electric push rod is activated.

[0018] Furthermore, the transmission component includes a sleeve that is slidably mounted on the outside of the drive shaft. The sleeve is rotatably mounted on the movable plate via a bearing, and a guide gear is fixedly mounted on the upper part of the sleeve.

[0019] The above technical solution enables the rotating plate and the bearing component to rotate when the guide gear meshes with either the first or second gear ring.

[0020] 3. Beneficial effects:

[0021] Compared with the prior art, the positioning device for metal casting processing of this utility model, through the setting of the drive module, can meet the multi-directional processing needs of castings and effectively avoid the processing dead angles formed by the clamping parts. The specific details are as follows:

[0022] The metal casting to be processed is placed on the support plate. The two electric push rods extend and retract synchronously, pushing the clamping plates on both sides closer to the casting until the casting is clamped, preventing the casting from loosening or deforming during processing. At the same time, the height of the support plate can be adjusted by extending and retracting the electric push rod, which, together with the clamping device, can achieve adaptive positioning for castings of different sizes and shapes. After clamping, the support plate can be moved away from the casting to avoid friction when the casting rotates with the clamping device.

[0023] When the electric push rod three moves the transmission component on the movable plate up and down, and the guide gear in the transmission component meshes with the first gear ring, the motor is started. The motor drives the drive shaft to rotate through the rotating shaft. Then, by utilizing the cooperation between the drive shaft and the sleeve, the guide gear is driven to rotate. The guide gear, through its meshing with the first gear ring, drives the metal casting clamped on the rotating plate to rotate 360 ​​degrees, meeting the needs of multi-directional processing. When the adjusting component drives the guide gear to mesh with the second gear ring, the clamping is released and the motor is started again, driving the casting on the bearing plate to rotate. After adjusting to the appropriate angle, it is re-clamped, solving the dead angle problem caused by the clamping part. Attached Figure Description

[0034] Please see Figure 1-5A positioning device for metal casting processing includes a frame 1, a platform 2 fixedly mounted on the upper end of the frame 1, a bearing 6 rotatably mounted on the middle of the upper end of the platform 2, a rotating plate 3 with a bearing sleeve on the outer side of the bearing 6, the rotating plate 3 being rotatably mounted on the platform 2, and a clamp 4 mounted on the rotating plate 3; a toothed ring 5 fixedly mounted on the inner side of the lower end of the rotating plate 3, a toothed ring 62 mounted on the outer side of the lower part of the bearing 6, and a drive module installed between the rotating plate 3 and the bearing 6. The drive module includes a drive component 7 and an adjusting component 8 mounted on the platform 2, the output end of the drive component 7 and the output end of the adjusting component 8 are connected. A transmission component 9 is installed between the ends. The drive module drives the rotating plate 3 and the carrier 6 to rotate through the cooperation of the gear ring 5 and the gear ring 62 respectively. The clamp 4 includes two electric push rods 41, which are symmetrically distributed about the center of the carrier 6. The output end of the electric push rod 41 is equipped with a clamping plate 42. The carrier 6 includes a rotating cylinder 61 mounted on the platform 2 by bearings. An electric push rod 63 is fixedly installed inside the rotating cylinder 61. The output end of the electric push rod 63 is equipped with a carrier plate 64. The gear ring 62 is sleeved and fixed on the lower outer side of the rotating cylinder 61.

[0035] First, place the metal casting to be processed on the support plate 64. The two electric push rods 41 extend and retract synchronously, pushing the clamping plates 42 on both sides closer to the casting until the casting is clamped, preventing the casting from loosening or deforming during processing. At the same time, the height of the support plate 64 can be adjusted by the extension and retraction of the electric push rod 63, which, together with the clamping device 4, enables the adaptive positioning of castings of different sizes and shapes. After clamping, the support plate 64 can be moved away from the casting to prevent friction from occurring when the casting rotates with the clamping device 4.

[0036] The driving component 7 includes a motor 71 mounted on the platform 2. The output shaft of the motor 71 is connected to a rotating shaft 72, and the upper end of the rotating shaft 72 is fixedly connected to a drive shaft 73 in a plum blossom shape. The adjusting component 8 includes an electric push rod 81 fixedly mounted on the platform 2. The output end of the electric push rod 81 is equipped with a movable plate 82. The transmission component 9 includes a sleeve 91 that slides up and down on the outside of the drive shaft 73. The sleeve 91 is rotatably mounted on the movable plate 82 through a bearing, and a guide gear 92 is fixedly mounted on the upper part of the sleeve 91.

[0037] When the electric push rod 81 pushes the transmission component 9 on the movable plate 82 to move up and down, when the guide gear 92 in the transmission component 9 meshes with the gear ring 5, the motor 71 is started. The motor 71 drives the drive shaft 73 to rotate through the rotating shaft 72. Then, by utilizing the cooperation between the drive shaft 73 and the sleeve 91, the guide gear 92 is driven to rotate. The guide gear 92, through its meshing with the gear ring 5, drives the metal casting clamped on the rotating plate 3 to rotate 360 ​​degrees, meeting the multi-directional processing requirements. When the adjusting component 8 drives the guide gear 92 to mesh with the gear ring 62, the clamping is released and the motor 71 is started again, driving the casting on the bearing plate 64 to rotate. After adjusting to the appropriate angle, it is re-clamped, solving the dead angle problem caused by the clamping part.

[0038] Working principle: When using this positioning device for metal casting machining, such as Figure 1-5 As shown, the metal casting to be processed is first placed on the support plate 64, and the casting is clamped by the clamp 4 to prevent the casting from loosening or deforming during processing. At the same time, the height of the support plate 64 can be adjusted to achieve adaptable positioning for castings of different sizes and shapes in conjunction with the clamp 4. The guide gear 92 is driven by the adjusting component 8 to mesh with the first gear ring 5 and the second gear ring 62 respectively. Then, the guide gear 92 is driven to rotate by the driving component 7. When the guide gear 92 is meshed with the first gear ring 5, it drives the metal casting clamped on the rotating plate 3 to rotate 360 ​​degrees to meet the multi-directional processing requirements. When the guide gear 92 is meshed with the second gear ring 62, the clamping is released and the motor 71 is restarted to drive the casting on the support plate 64 to rotate. After adjusting to the appropriate angle, it is clamped again to solve the dead angle problem caused by the clamping part.
