Description
Technical Field
[0001] This application relates to the technical field of linkage arm processing, and particularly to a tooling for processing linkage arms. Background Art
[0002] The connecting rod arm can also be called link drive. It is a rigid rod that connects components in a rotating shaft manner at the endpoints. The rod drive mechanism is a mechanism that connects components to each other by hinges and slides to achieve motion transformation and power transmission.
[0003] A linkage arm is a structure that connects more than two objects to achieve a linkage effect. The structure of the linkage arm is usually set to be irregular. Connection holes for facilitating the fixation of the linkage arm and the object are provided on the side wall of the linkage arm. In order to make the connection between the linkage arm and the object more precise, relatively high requirements are imposed on the opening position and dimension accuracy of the holes on the side wall of the linkage arm.
[0004] Currently, when processing a connecting arm, a fixture is usually used to clamp and fix the connecting arm at multiple points, and the blank part of the connecting arm is fixed on a numerically controlled machine tool for processing. This simple clamping and fixing method has the possibility of the part shifting during the processing, so there is room for improvement.
[0005] Therefore, this application proposes a tooling for processing linkage arms. Utility Model Content
[0006] A tooling for processing linkage arms proposed in this application is used to solve the problems raised in the above background art. By setting a positioning mechanism, a fixing plate is installed on the main body of the numerically controlled machine tool for processing the linkage arm body. A positioning hole matching the linkage arm body is provided in the fixing plate. The staff inserts the linkage arm body into the positioning hole, and then inserts a positioning rod into the positioning hole and rotates it clockwise. The positioning rod is connected to the positioning hole through the first thread and the second thread. The positioning block on the positioning rod fixes the linkage arm body at multiple points. Under the combined action of the positioning rod and the positioning hole, the linkage arm body is better fixed, reducing the possibility of dislocation during the processing of the linkage arm body, improving the stability of the fixed connecting arm, thereby improving the processing accuracy of the linkage arm body and greatly enhancing the practicality of the device.
[0007] In order to achieve the above object, this application adopts the following technical solutions:

A positioning rod is arranged inside each positioning hole. A positioning block is fixedly connected to the top end of each positioning rod, and the outside of each positioning block is in contact with the outside of the linkage arm body.
[0009] As a preferred embodiment, a connecting mechanism is arranged between each positioning hole and the positioning rod. The connecting mechanism includes a first thread and a second thread.

[0012] After inserting the positioning rod into the positioning hole, rotate the positioning rod clockwise to connect the second thread on the positioning rod with the first thread in the positioning hole, thereby achieving the quick positioning effect of the positioning rod, and thus enhancing the practicality of the device.
[0013] As a preferred embodiment, two fixing blocks are fixedly connected inside the CNC machine tool main body, and the two fixing blocks are located on both sides of the fixing plate.

[0015] As a preferred embodiment, a reinforcement mechanism is fixedly connected to each of the two fixing blocks. The reinforcement mechanism includes an electric telescopic rod, a first clamping plate, a second clamping plate, a clamping groove and a groove.
[0016] By setting the reinforcement mechanism, the positioning mechanism is reinforced to prevent a certain pressure from squeezing the positioning block during the processing of the linkage arm body, affecting the processing position of the linkage arm body and reducing the processing accuracy, thereby further improving the stability during the processing of the linkage arm body, and thus enhancing the practicality of the device.

[0018] The electric telescopic rods drive the first clamping plate and the second clamping plate to move towards the direction of the linkage arm body. At this time, the clamping grooves on the first clamping plate and the second clamping plate will be stuck on the outer side of the linkage arm body, thereby improving the practicability of the device.
[0019] As a preferred embodiment, clamping grooves are respectively formed inside the first clamping plate and the second clamping plate, and a plurality of grooves matching the positioning blocks are formed inside the two clamping grooves;
[0020] By providing the grooves, they will be stuck outside the corresponding positioning blocks to reinforce the positioning mechanism, thereby improving the practicability of the device.

Detailed Embodiment
[0030] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments.
[0031] Refer to Figures 1 - 3 , a fixture for processing a linkage arm, including a main body 1 of a numerical control machine tool, a fixing plate 2, a positioning mechanism 4, a connection mechanism 5, and a linkage arm body 6. The fixing plate 2 is installed inside the main body 1 of the numerical control machine tool.
[0032] A positioning mechanism 4 is provided on the fixing plate 2. The positioning mechanism 4 includes positioning holes 41, positioning rods 42 and positioning blocks 43. Each positioning hole 41 is opened on the fixing plate 2. A positioning rod 42 is provided inside each positioning hole 41. A positioning block 43 is fixedly connected to the top of each positioning rod 42, and the outside of each positioning block 43 contacts the outside of the linkage arm body 6; By installing the fixing plate 2 on the main body 1 of the numerical control machine tool for processing the linkage arm body 6, positioning holes 41 matching the linkage arm body 6 are opened in the fixing plate 2. The staff inserts the linkage arm body 6 into the positioning holes 41, then inserts the positioning rods 42 into the positioning holes 41 and rotates clockwise. The positioning rods 42 are connected to the positioning holes 41 through the first thread 51 and the second thread 52. The positioning blocks 43 on the positioning rods 42 fix the linkage arm body 6 at multiple points. Under the combined action of the positioning rods 42 and the positioning holes 41, the linkage arm body 6 is better fixed, reducing the possibility of dislocation during the processing of the linkage arm body 6, thereby improving the processing accuracy of the linkage arm body 6.
[0033] A connecting mechanism 5 is provided between each positioning hole 41 and the positioning rod 42. The connecting mechanism 5 includes a first thread 51 and a second thread 52; By providing the connecting mechanism 5, the first thread 51 and the second thread 52, the positioning rod 42 can be quickly positioned in the positioning hole 41 by using the first thread 51 and the second thread 52, improving the positioning efficiency, thereby enhancing the practicality of the device.
[0034] Each first thread 51 is provided inside the positioning hole 41. A second thread 52 is provided on the outside of each positioning rod 42, and each positioning rod 42 is threadedly connected to the positioning hole 41 through the first thread 51 and the second thread 52; After inserting the positioning rod 42 into the positioning hole 41, rotate the positioning rod 42 clockwise to connect the second thread 52 on the positioning rod 42 with the first thread 51 in the positioning hole 41, thereby achieving the quick positioning effect of the positioning rod 42, thereby enhancing the practicality of the device.
[0035] Two fixing blocks 7 are fixedly connected inside the main body 1 of the numerical control machine tool, and the two fixing blocks 7 are located on both sides of the fixing plate 2; By providing the fixing blocks 7, the two fixing blocks 7 are fixed to the main body 1 of the numerical control machine tool by welding for fixing the reinforcement mechanism 8, and the fixing method is stable and firm, thereby enhancing the practicality of the device.
[0036] Reinforcing mechanisms 8 are fixedly connected to both of the two fixed blocks 7. The reinforcing mechanism 8 includes an electric telescopic rod 81, a first clamping plate 82, a second clamping plate 83, a card slot 84, and a groove 85. By providing the reinforcing mechanism 8, the positioning mechanism 4 is reinforced to prevent the positioning block 43 from being squeezed under a certain pressure during the machining of the linkage arm body 6, which may affect the machining position of the linkage arm body 6 and reduce the machining accuracy. Therefore, the stability during the machining of the linkage arm body 6 is further improved, thereby enhancing the practicality of the device.
[0037] Both of the two electric telescopic rods 81 are fixedly connected to the fixed block 7, and the two electric telescopic rods 81 are respectively fixedly connected to the opposite sides of the fixed block 7. The telescopic ends of the two electric telescopic rods 81 are respectively fixedly connected to a first clamping plate 82 and a second clamping plate 83. By driving the first clamping plate 82 and the second clamping plate 83 to move towards the linkage arm body 6 through the electric telescopic rod 81, at this time, the card slots 84 on the first clamping plate 82 and the second clamping plate 83 will be stuck on the outer side of the linkage arm body 6, thereby enhancing the practicality of the device.
[0038] Card slots 84 are respectively formed inside the first clamping plate 82 and the second clamping plate 83, and a plurality of grooves 85 matching the positioning blocks 43 are formed inside the two card slots 84. By providing the grooves 85, they will be stuck outside the corresponding positioning blocks 43 to reinforce the positioning mechanism 4, thereby enhancing the practicality of the device.
[0039] An installation mechanism 3 is provided on the fixing plate 2. The installation mechanism 3 includes installation holes 31 and fixing bolts 32. Each installation hole 31 is formed in the fixing plate 2, and a fixing bolt 32 is threadedly connected inside each installation hole 31, and the bottom end of each fixing bolt 32 extends into the main body of the numerical control machine tool 1. By providing the installation mechanism 3, when installing the fixing plate 2, the fixing bolt 32 is inserted into the installation hole 31 by a tool to fix the fixing plate 2. The structure is simple, facilitating installation and quick disassembly. When the fixing plate 2 is used to a certain extent, the positioning holes 41 may be affected by pressure and have different sizes, thus affecting the machining accuracy. Therefore, it is necessary to replace the fixing plate 2 for positioning to improve the machining accuracy of the linkage arm body 6, thereby enhancing the practicality of the device.
[0040] Working principle: By installing a fixing plate 2 on the main body 1 of the numerical control machine tool for processing the linkage arm body 6, a positioning hole 41 matching the linkage arm body 6 is opened in the fixing plate 2. The staff inserts the linkage arm body 6 into the positioning hole 41, then inserts a positioning rod 42 into the positioning hole 41 and rotates it clockwise. The positioning rod 42 is connected to the positioning hole 41 through the first thread 51 and the second thread 52. The positioning block 43 on the positioning rod 42 fixes the linkage arm body 6 at multiple points. Under the combined action of the positioning rod 42 and the positioning hole 41, the linkage arm body 6 is better fixed, reducing the possibility of dislocation during the processing of the linkage arm body 6, thereby improving the processing accuracy of the linkage arm body 6.
[0041] This tooling can better fix the linkage arm body 6 on the main body 1 of the numerical control machine tool, reduce the possibility of the linkage arm body 6 shifting during processing, improve the stability of the fixed connecting arm, and thus improve the processing accuracy of the connecting arm.
[0042] By setting the reinforcement mechanism 8, after the linkage arm body 6 is positioned by the positioning mechanism 4, the electric telescopic rod 81 is started. The electric telescopic rod 81 drives the first clamping plate 82 and the second clamping plate 83 to move towards the linkage arm body 6. At this time, the clamping grooves 84 on the first clamping plate 82 and the second clamping plate 83 will be stuck on the outer side of the linkage arm body 6. By setting the groove 85, it will be stuck outside the corresponding positioning block 43 to reinforce the positioning mechanism 4, preventing a certain pressure from squeezing the positioning block 43 during the processing of the linkage arm body 6, affecting the processing position of the linkage arm body 6 and reducing the processing accuracy, thereby further improving the stability during the processing of the linkage arm body 6.
[0043] By setting the installation mechanism 3, when installing the fixing plate 2, the fixing bolt 32 is inserted into the installation hole 31 by a tool to fix the fixing plate 2. The structure is simple, easy to install and quickly disassemble. When the fixing plate 2 is used to a certain extent, the positioning holes 41 may vary in size under the influence of pressure, thus affecting the processing accuracy. Then, the fixing plate 2 needs to be replaced to improve the processing accuracy of the linkage arm body 6.
[0044] By setting the connecting mechanism 5, the first thread 51 and the second thread 52, using the first thread 51 and the second thread 52, the positioning rod 42 can be quickly positioned in the positioning hole 41, improving the positioning efficiency. After the positioning rod 42 is inserted into the positioning hole 41, the positioning rod 42 is rotated clockwise so that the second thread 52 on the positioning rod 42 is connected to the first thread 51 in the positioning hole 41, thereby achieving the quick positioning effect of the positioning rod 42.
[0045] The above are only the preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution of the present application and its utility model concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present application.
