Description

Technical Field

[0001] This application relates to the field of machining technology, specifically a rapid automatic tooling. Background Technology

[0002] Thin-shell aluminum alloy workpieces are generally first die-cast using a die-casting machine. After die-casting, they are then drilled using equipment such as CNC lathes or CNC machining centers. In order to fix the thin-shell aluminum alloy workpieces on CNC lathes or other equipment for processing, special tooling fixtures are required.

[0003] However, among the existing rapid automatic tooling, there is a lack of tooling that can clamp workpieces in large batches and a lack of tooling that can clamp workpieces quickly. Therefore, it is necessary to design a tooling that has the advantages of clamping aluminum alloy thin-shell workpieces in large batches and quickly. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a rapid automatic tooling that has the advantages of simultaneously clamping multiple workpieces and quickly clamping and positioning them, thus solving the problem of the lack of tooling capable of clamping large batches of aluminum alloy thin-shell workpieces and quickly positioning and clamping them.

[0005] To achieve the above objectives, this application provides the following technical solution: a rapid automatic tooling fixture, comprising a positioning seat, wherein the bottom surface of the positioning seat is fixedly connected with telescopic rods arranged at equal intervals, the output end of each telescopic rod is fixedly connected with a connecting rod, the outer surface of each connecting rod is fixedly connected with a clamping member, the upper surface of each clamping member is provided with two positioning holes, the upper surface of the positioning seat is fixedly connected with positioning pins arranged at equal intervals, the outer surface of each positioning pin is slidably connected with the inner wall of the corresponding positioning hole, the upper surface of the positioning seat is provided with positioning grooves arranged at equal intervals, and the inner wall of each positioning groove is used to place a workpiece body.

[0006] With the above solution, when workpiece positioning is required, the workpiece body is placed inside the corresponding positioning slot, and then all telescopic rods are activated simultaneously, causing the telescopic rods to retract along with the connecting rods. Due to the fixed connection between the connecting rods and the clamping components, the clamping components can descend. Through the connection between the positioning holes on the surface of the clamping components and the positioning pins, the clamping components are limited, allowing them to hold the workpiece body. This device can simultaneously process and position multiple workpiece bodies, and can quickly and accurately clamp the workpiece bodies, improving processing efficiency. The telescopic rods use pneumatic telescopic movement to achieve rapid action.

[0007] Furthermore, a mounting base plate is provided below the positioning seat, and a support column arranged at equal intervals is fixedly connected to the upper surface of the mounting base plate. The top of each support column is fixedly connected to the bottom surface of the positioning seat by fixing bolts.

[0008] The above method involves placing the mounting base plate below the positioning seat and installing the support columns on the upper surface of the mounting base plate. The mounting base plate is then connected to the mounting holes on the surface of the positioning seat using fixing bolts. These fixing bolts secure the positioning seat to the four support columns, thus achieving the installation of the positioning seat.

[0009] Furthermore, the upper surface of the mounting base plate is fixedly connected with shells arranged at equal intervals, and the inner wall of each shell is slidably connected with a limit block.

[0010] The above scheme involves installing the housing on the upper surface of the mounting base plate as a fixed connection to achieve the positioning and installation effect of the housing, and installing the limiting block on the inner wall of the corresponding housing as a sliding connection. The limiting effect of the limiting block can be achieved by the contour of the inner wall of the housing.

[0011] Furthermore, each of the limiting blocks has a mounting block fixedly connected to its upper surface, and each of the mounting blocks has a rubber top block fixedly mounted on its upper surface.

[0012] The above scheme fixes the mounting block to the upper surface of the limiting block, forming a fixed connection. The lifting and lowering of the mounting block can achieve the lifting and lowering effect of the mounting block. The rubber top block is installed on the upper surface of the mounting block, and the surface of the rubber top block slides against the inner wall of the positioning groove on the positioning seat surface, so that the rubber top block can push out the workpiece body placed on the inner wall of the positioning groove.

[0013] Furthermore, a spring is fixedly connected to the bottom surface of each limiting block, and the bottom end of each spring is fixedly connected to the inner bottom wall of the corresponding housing.

[0014] With the above solution, the spring is installed on the bottom surface of the limiting block and set as a fixed connection. The bottom end of the spring is also connected to the corresponding inner bottom wall of the housing and set as a fixed connection. The spring can press the limiting block tightly. When the clamping part releases the clamping of the workpiece body, the rubber top block can push the workpiece body out under the action of the spring, making it easy for the operator to take the workpiece body out of the positioning groove.

[0015] Furthermore, each of the housings has a sleeve fixedly connected to its inner bottom wall, the top of each sleeve is fixedly connected to the bottom surface of the corresponding limiting block, and a limiting groove is formed on the outer surface of each housing.

[0016] The above scheme involves installing the sleeve on the inner bottom wall of the housing for a fixed connection. The sleeve includes a hollow large cylinder and a small cylinder that fits the inner wall of the large cylinder. It can extend and retract freely to achieve the positioning effect of the limiting block. The limiting groove is opened on the surface of the housing to achieve the positioning of the limiting groove.

[0017] Furthermore, each of the limiting grooves has a limiting component slidably connected to its inner wall, the back of each limiting component is fixedly connected to the outer surface of the corresponding limiting block, and each limiting component has a bolt rotatably connected to its inner wall.

[0018] The above scheme involves placing the limiting component on the inner wall of the corresponding limiting groove and setting it as a sliding connection to achieve the limiting effect of the limiting component. The back of the limiting component is connected to the outer surface of the corresponding limiting block. By pressing the limiting component, the corresponding limiting block can be raised and lowered. The bolt is installed on the inner wall of the corresponding limiting component and is set as a rotating connection between them to achieve the limiting effect of the bolt.

[0019] Furthermore, each of the outer surfaces of the housing is fixedly connected to a connector, and the inner wall of each connector is threadedly connected to the outer surface of the corresponding bolt.

[0020] The above scheme involves installing the connector on the outer surface of the corresponding housing and setting it as a fixed connection to fix the connector. The surface of the bolt is connected to the inner wall of the connector, and a threaded connection is set. The connection with the connector can be achieved by rotating the bolt. When the limiting piece is pressed and the bolt is rotated to connect with the connector, the rubber top block will not continue to move upward, thus limiting the movement of the rubber top block.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This rapid automatic tooling uses components such as a telescopic rod, clamping parts, positioning pins, and positioning slots to place multiple workpieces into corresponding positioning slots. Simultaneously, the telescopic rod retracts, causing the connecting rod to retract and lowering the clamping parts. The clamping parts are limited by the connection between the positioning holes and positioning pins, allowing for rapid positioning and clamping of multiple workpieces. After processing, the clamping parts rise under the action of the telescopic rod. At this point, the spring causes the limiting block and mounting block to rise, and the rubber top block pushes the workpieces out, making it easy for the operator to remove the processed workpieces.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment, a rapid automatic tooling includes a positioning base 1.

[0026] Please see Figure 1 , Figure 2 and Figure 4 A mounting base plate 9 is provided below the positioning seat 1. Support columns 10 arranged at equal intervals are fixedly connected to the upper surface of the mounting base plate 9. The top of each support column 10 is fixedly connected to the bottom surface of the positioning seat 1 by fixing bolts 11.

The fixing bolts 11 are connected to the mounting holes on the surface of the positioning seat 1, and the fixing bolts 11 can fix the positioning seat 1 to the four support columns 10, thereby realizing the installation of the positioning seat 1.

[0027] Please see Figure 1 , Figure 2 and Figure 5 The upper surface of the mounting base plate 9 is fixedly connected with housings 12 arranged at equal intervals. Each housing 12 has a limit block 14 slidably connected to its inner wall. The housing 12 is installed on the upper surface of the mounting base plate 9 as a fixed connection to achieve the positioning and installation effect of the housing 12. The limit block 14 is installed on the inner wall of the corresponding housing 12 as a sliding connection to achieve the limiting effect of the limit block 14 through the inner wall contour of the housing 12.

[0028] Please see Figure 5 Each limiting block 14 has a mounting block 15 fixedly connected to its upper surface, and a rubber top block 16 is fixedly installed on the upper surface of each mounting block 15. The mounting block 15 is fixed to the upper surface of the limiting block 14 and is set as a fixed connection. The lifting and lowering of the limiting block 14 can achieve the lifting and lowering effect of the mounting block 15. The rubber top block 16 is installed on the upper surface of the mounting block 15, and the surface of the rubber top block 16 slides against the inner wall of the positioning groove 7 on the surface of the positioning seat 1, so that the rubber top block 16 can push out the workpiece body 8 placed on the inner wall of the positioning groove 7.

[0029] Please see Figure 5 Each limiting block 14 has a spring 13 fixedly connected to its bottom surface. The bottom end of each spring 13 is fixedly connected to the inner bottom wall of the corresponding housing 12. The spring 13 is installed on the bottom surface of the limiting block 14 and is fixedly connected to the inner bottom wall of the corresponding housing 12. The spring 13 can press the limiting block 14 tightly. When the clamping member 4 releases the clamping member from the workpiece body 8, the rubber top block 16 can push the workpiece body 8 out under the action of the spring 13, making it easy for the operator to take the workpiece body 8 out of the positioning groove 7.

[0030] Please see Figure 1 and Figure 5 Each housing 12 has a sleeve 20 fixedly connected to its inner bottom wall. The top of each sleeve 20 is fixedly connected to the bottom surface of the corresponding limiting block 14. Each housing 12 has a limiting groove 19 on its outer surface. The sleeve 20 is installed on the inner bottom wall of the housing 12 and is fixedly connected. The sleeve 20 includes a hollow large cylinder and a small cylinder that fits the inner wall of the large cylinder. It can extend and retract freely to achieve the positioning effect of the limiting block 14. The limiting groove 19 is opened on the surface of the housing 12 to achieve the positioning of the limiting groove 19.

[0031] Please see Figure 5Each limiting groove 19 has a limiting member 17 slidably connected to its inner wall. The back of each limiting member 17 is fixedly connected to the outer surface of the corresponding limiting block 14. Each limiting member 17 has a bolt 18 rotatably connected to its inner wall. The limiting member 17 is placed on the inner wall of the corresponding limiting groove 19 and is set to a sliding connection to achieve the limiting effect of the limiting member 17. The back of the limiting member 17 is connected to the outer surface of the corresponding limiting block 14. By pressing the limiting member 17, the corresponding limiting block 14 can be raised and lowered. The bolt 18 is installed on the inner wall of the corresponding limiting member 17 and is set to a rotatable connection between them to achieve the limiting effect of the bolt 18.

[0032] Please see Figure 1 , Figure 2 and Figure 5 Each housing 12 has a connector 21 fixedly connected to its outer surface. The inner wall of each connector 21 is threadedly connected to the outer surface of the corresponding bolt 18. The connector 21 is installed on the outer surface of the corresponding housing 12 and is fixedly connected to fix the connector 21. The surface of the bolt 18 is connected to the inner wall of the connector 21 and is threaded. The connection between the bolt 18 and the connector 21 can be achieved by rotating the bolt 18. When the limiting member 17 is pressed and the bolt 18 is rotated to connect with the connector 21, the rubber top block 16 will not continue to move upward, thus limiting the movement of the rubber top block 16.

[0033] This embodiment of a rapid automatic tooling system includes components such as a telescopic rod 2, a clamping member 4, a positioning pin 6, and a positioning groove 7. Multiple workpiece bodies 8 are placed inside the corresponding positioning grooves 7. Simultaneously, the telescopic rod 2 retracts, causing the connecting rod 3 to retract, which in turn lowers the clamping member 4. The clamping member 4 is limited by the connection between the positioning hole 5 and the positioning pin 6, allowing it to quickly position and clamp multiple workpiece bodies 8. After processing, the clamping member 4 rises under the action of the telescopic rod 2. At this time, under the action of the spring 13, the limiting block 14 and the mounting block 15 rise, and the rubber top block 16 pushes out the workpiece body 8, making it convenient for the operator to remove the processed workpiece body 8.

[0034] It should be noted that the telescopic rod 2 is a cylinder, and the connecting rod 3 is the piston rod of the cylinder. The clamping part 4 is fixed to the top of the piston rod by bolts, so that the telescopic rod 2 drives the clamping part 4 to rise and fall. The connecting rod 3 and the positioning seat 1 are slidably connected, which makes it easy for the connecting rod 3 to move up and down through the telescopic rod 2. The upper surface of the mounting base plate 9 and the bottom surface of the telescopic rod 2 are also fixed, which can improve the stability of the telescopic rod 2 when it is working.

[0035] The working principle of the above embodiments is as follows: First, place the workpiece body 8 inside the corresponding positioning groove 7. Then, simultaneously activate the four telescopic rods 2, causing the four connecting rods 3 to descend simultaneously, which in turn lowers the corresponding clamping parts 4. Through the connection between the positioning hole 5 and the positioning pin 6, the clamping parts 4 are limited. At this time, the clamping parts 4 can clamp and position the cylindrical end of the workpiece body 8. After processing, the telescopic rods 2 drive the connecting rods 3 to rise, causing the clamping parts 4 to release the limitation on the workpiece body 8. At this time, under the action of the spring 13, the rubber top block 16 pushes out the corresponding workpiece body 8, making it easy for the operator to take out the processed workpiece body 8. When it is not necessary to use the rubber top block 16 to push out the workpiece body 8, press the corresponding limiting part 17, so that the bolt part 18 contacts the corresponding connecting part 21. Then rotate the bolt part 18 to connect the bolt part 18 with the connecting part 21. At this time, the spring 13 will not push the rubber top block 16, and the rubber top block 16 will not continue to push out the processed workpiece body 8.
