Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, specifically a fixing mechanism for precision casting processing. Background Technology

[0002] As the manufacturing industry moves towards high-end and intelligent manufacturing, precision castings, as the core foundation for constructing key components, directly impact the development of fields such as aerospace and high-end equipment manufacturing due to their machining accuracy and production efficiency. In the production process of precision castings, the fixing mechanism, as the hub connecting upstream and downstream processes, undertakes the crucial tasks of precise positioning and efficient transfer of castings.

[0003] Traditional fixing devices rely heavily on manual operation for clamping and transferring castings. This is not only labor-intensive and inefficient, but most fixing devices can only perform a single fixing function, and manual assistance is still required for loading and unloading. This prevents seamless integration with other processes on the production line, leading to production interruptions and hindering continuous, large-scale production operations. This not only increases labor costs but also limits the improvement of production efficiency, making it difficult for companies to respond quickly to market demands when faced with a large number of orders, thus missing development opportunities.

[0004] Therefore, we propose a fixing mechanism for precision casting 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 fixing mechanism for precision casting machining, 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, this utility model provides the following technical solution: a fixing mechanism for precision casting processing, including a base plate, a first conveying component installed on the upper left side of the base plate, and a second conveying component installed on the upper right side of the base plate, and a casting transfer module installed in the middle of the base plate;

[0009] The casting transposition module includes a rotating mechanism mounted on a base plate. A connector is installed at the output end of the rotating mechanism. A working plate is fixed above the connector. A groove is provided on the working plate, and a set of clamping members is provided on both sides of the groove. The two sets of clamping members arranged opposite each other are used to clamp the casting.

[0010] Furthermore, the rotating mechanism includes a mounting base fixed to the base plate, on which a driving gear and a force-receiving gear ring are mounted via bearings, and the driving gear and the force-receiving gear ring mesh with each other.

[0011] The above technical solution enables the driving gear to rotate synchronously when the motor drives the driving gear to rotate.

[0012] Furthermore, the connector includes an outer frame fixed directly below the work plate, a spline shaft fixed in the middle of the inner side of the outer frame, and two movable blocks symmetrically fixed on the outer side of the outer frame.

[0013] The above technical solution enables the spline shaft, outer frame, and moving block to move synchronously.

[0014] Furthermore, the force-bearing gear ring is fitted and sleeved on the outer side of the middle part of the spline shaft, and the gear ratio between the force-bearing gear ring and the driving gear is 2:1.

[0015] The above technical solution enables the driving gear to rotate half a turn after one rotation of the driving gear, and the rotation of the force-bearing gear ring will drive the spline shaft to rotate synchronously.

[0016] Furthermore, a fixing seat is sleeved on the outer side of the connector. The fixing seat is fixedly installed in the upper middle part of the base plate, and the inner wall of the fixing seat is provided with a movable groove. The movable groove includes two first sliding grooves and two second sliding grooves. The two first sliding grooves and two second sliding grooves are connected end to end in an alternating manner. The first sliding groove is arranged in a semi-circular shape, and the second sliding groove is arranged in a "V" shape. The movable block is fitted and slidably disposed inside the movable groove.

[0017] The above technical solution allows the movable block to slide within the movable groove. When the bottom of the second groove slides towards the first groove on one side, it can drive the movable block to move upward.

[0018] Furthermore, the clamping component includes a cylinder fixed to the work plate, the output end of the cylinder is connected to the clamping plate, and two grooves are symmetrically arranged about the center of the work plate.

[0019] The above technical solution enables the cylinder to start and drive the clamping plate to clamp the casting.

[0020] 3. Beneficial effects:

[0021] Compared with the prior art, the fixing mechanism for precision casting processing of this utility model, through the cooperation of the first conveyor, the second conveyor and the casting transfer module, realizes automatic loading and unloading of castings, improves production efficiency, and at the same time avoids friction between the bottom of the casting and other parts during rotation, ensuring casting quality and extending the service life of the equipment. The specific details are as follows:

[0022] The first conveyor transports the casting to a groove on the side of the work plate. Then, the clamping parts on both sides of the groove clamp and fix the casting. The motor at the end of the drive gear is then started to drive the drive gear to rotate. The drive gear drives the force gear ring to rotate through the meshing action between the drive gear and the force gear ring. The force gear ring drives the outer frame and the work plate to rotate synchronously through the spline shaft. This can drive the casting fixed between the two clamping parts to rotate onto the second conveyor for subsequent processing and unloading, thereby realizing automatic loading and unloading of castings and improving production efficiency.

[0023] When the spline shaft drives the outer frame to rotate inside the fixed seat, the movable block is slidably set inside the movable groove. When it slides from the bottom of the second slide groove to the first slide groove on one side, it will drive the outer frame to move upward inside the fixed seat, thereby driving the work plate to move upward. This can drive the casting away from the first conveyor, avoiding friction between the bottom of the casting and other parts during rotation, effectively protecting the surface quality of the casting and reducing the defect rate caused by wear.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0034] Please see Figure 1-5A fixing mechanism for precision casting processing includes a base plate 1, a first conveying component 2 installed on the upper left side of the base plate 1, and a second conveying component 3 installed on the upper right side of the base plate 1. A casting transfer module is installed in the middle of the base plate 1. The casting transfer module includes a rotating mechanism 4 installed on the base plate 1. A connecting component 51 is installed at the output end of the rotating mechanism 4. A working plate 5 is fixed above the connecting component 51. A groove 7 is provided on the working plate 5, and a set of clamping components 8 is provided on both sides of the groove 7. The two sets of clamping components 8 arranged opposite each other are used to clamp the casting. The clamping component 8 includes a cylinder 811 fixed on the working plate 5. The output end of the cylinder 811 is connected to a clamping plate 812. There are two grooves 7 arranged symmetrically about the center of the working plate 5.

[0035] The first conveyor 2 conveys the casting to the groove 7 opened on the side of the working plate 5. Then, the clamping parts 8 on both sides of the groove 7 clamp and fix the casting. Then, the casting position is transferred by the casting transfer module for subsequent processing and unloading, thereby realizing automatic loading and unloading of castings and improving production efficiency.

[0036] The rotating mechanism 4 includes a mounting base 41 fixed on the base plate 1. A driving gear 42 and a force-receiving gear ring 43 are mounted on the mounting base 41 via bearings, and the driving gear 42 and the force-receiving gear ring 43 mesh with each other. The connecting member 51 includes an outer frame 511 fixed directly below the working plate 5. A spline shaft 512 is fixed in the middle of the inner side of the outer frame 511, and two movable blocks 513 are symmetrically fixed in the outer side of the outer frame 511. The force-receiving gear ring 43 is fitted and sleeved on the outer side of the middle part of the spline shaft 512, and the force-receiving gear ring 43 meshes with the driving gear 42. The gear ratio between the wheels 42 is 2:1; a fixed seat 6 is sleeved on the outer side of the connector 51. The fixed seat 6 is fixedly installed in the upper middle part of the base plate 1, and the inner wall of the fixed seat 6 is provided with a movable groove 61. The movable groove 61 includes two first sliding grooves 611 and two second sliding grooves 612. The two first sliding grooves 611 and the two second sliding grooves 612 are connected end to end in an alternating manner. The first sliding groove 611 is semi-circular, and the second sliding groove 612 is "V" shaped. The movable block 513 is fitted and slidably disposed inside the movable groove 61.

[0037] After the casting is clamped and fixed, the motor at the end of the drive gear 42 is started, driving the drive gear 42 to rotate. The drive gear 42 drives the force gear ring 43 to rotate through the meshing action between the drive gear 42 and the force gear ring 43. The force gear ring 43 drives the outer frame 511 and the working plate 5 to rotate synchronously through the spline shaft 512, thereby driving the casting fixed between the two clamping parts 8 to rotate onto the second conveyor 3. When the spline shaft 512 drives the outer frame 511 to rotate inside the fixed seat 6, since the movable block 513 is slidably set inside the movable groove 61, when the bottom of the second slide groove 612 slides to one side of the first slide groove 611, it will drive the outer frame 511 to move upward inside the fixed seat 6, thereby driving the working plate 5 to move upward. This can drive the casting away from the first conveyor 2, avoiding friction between the bottom of the casting and other parts during rotation, effectively protecting the surface quality of the casting and reducing the defect rate caused by wear.

[0038] Working principle: When using this precision casting machining fixing mechanism, such as Figure 1-5 As shown, the first conveyor 2 first conveys the casting to the groove 7 opened on the side of the working plate 5, and then the casting is clamped and fixed by the clamping member 8. Then, the motor at the end of the drive gear 42 is started, and the casting transfer module drives the casting to rotate and move to the second conveyor 3 for subsequent processing and unloading. This realizes the automatic loading and unloading of castings, improves production efficiency. In the process of using the casting transfer module to drive the casting from the first conveyor 2 to the second conveyor 3, the casting can be moved away from the first conveyor 1 and other components, which effectively protects the surface quality of the casting, reduces the defect rate caused by wear, and extends the service life.

[0039] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
