Description

Technical Field

Its main technical effect is: the guide block is arranged on the clamping surface of the three claws, so that during the clamping and positioning process, the positioning head arranged at the front end of the guide block can be pressed tightly into the tooth groove of the internal teeth, so that the teeth can be used as the reference for processing and positioning in the subsequent processing (flange hole on the end face).

[0023] See also Figure 1 —5. A coupling rapid positioning processing tool, comprising a fixed seat 1, a positioning groove 11 is symmetrically opened on the outer wall of the top of the fixed seat 1, a clamping seat 2 is symmetrically and movably arranged on the top of the fixed seat 1, a driving mechanism 3 is arranged inside the fixed seat 1, the driving mechanism 3 is connected with the clamping seat 2 in a transmission manner, and the clamping seats 2 on both sides are driven to move away from each other by the driving mechanism 3, a clamping groove 21 is opened on the outer wall of the clamping seat 2, and the coupling and the fixed seat 1 are fixedly connected by the clamping groove 21 and the positioning groove 11.

[0024] Specifically, Figure 2As shown, positioning grooves 11 are symmetrically provided on the outer wall at the top of the fixed seat 1, and the positioning grooves 11 are specifically an arc-shaped structure. The positioning grooves 11 with an arc-shaped structure can be adapted to the shape of the outer wall of the coupling, so that they can fit the outer wall of the coupling, and then the coupling can be fixed to the positioning grooves 11. Specifically, a clamping seat 2 is movably provided on the top of the fixed seat 1, and a clamping groove 21 is provided on the outer wall on one side of the clamping seat 2. Preferably, the clamping groove 21 is adapted to the structure of the positioning groove 11, so that the coupling can be fixed by the clamping seat 2 and the positioning groove 11. A driving mechanism 3 is provided on the fixed seat 1, and the driving mechanism 3 maintains a transmission connection with the clamping seat 2. The driving mechanism 3 can drive the symmetrically arranged clamping seats 2 to keep moving away from each other, so that the coupling can be clamped by the clamping seat 2 and the positioning grooves 11.

[0025] The utility model drives multiple clamping seats 2 to maintain divergent movement through a driving mechanism 3, thereby being able to clamp multiple couplings through the clamping grooves 21 and the positioning grooves 11 on the clamping seats 2. Multiple couplings can be fixed at one time and multiple couplings can be clamped simultaneously, which can improve the production efficiency of batch processing of couplings.

[0026] As an embodiment provided by the utility model, Figure 3 and Figure 5 As shown, the driving mechanism 3 includes a hydraulic cylinder 31, a driving block 32, a linkage block 33 and an abutment sheet 38. The hydraulic cylinder 31 is fixedly mounted on the inner wall of one side of the fixing seat 1, and the output end of the hydraulic cylinder 31 penetrates and extends to the outer wall of one side of the fixing seat 1. The driving block 32 is connected to one end of the hydraulic cylinder 31 located outside the fixing seat 1 by bolts, and the abutment sheet 38 is fixedly mounted on the outer wall of one side of the driving block 32, so that when the output end of the hydraulic cylinder 31 moves upward, it can keep in contact with the abutment sheet 38, thereby driving the driving block 32 to keep moving upward, and the hydraulic cylinder 31 can drive the driving block 32 to keep lifting in the vertical direction. Figure 4 and Figure 5 As shown, the linkage block 33 is fixedly installed on the outer wall of one side of the clamping seat 2. The number of the linkage blocks 33 is specifically two. The two linkage blocks 33 are respectively installed on the outer walls of one side of the two clamping seats 2. The two linkage blocks 33 are respectively slidably connected to the driving blocks 32. The driving blocks 32 are driven by the hydraulic cylinder 31 to keep sliding, and further drive the two linkage blocks 33 to keep moving, thereby driving the clamping seats 2 on both sides to move away from each other, and cooperate with the positioning groove 11 to complete the clamping of the coupling.

The driving block 32 is slidably connected to the linkage block 33 through the inclined sliding block 35. When the driving block 32 keeps moving up and down under the drive of the hydraulic cylinder 31, the linkage block 33 can be synchronously driven to keep moving in the horizontal direction, thereby driving the clamping seat 2 to move away from or towards each other.

[0029] Further, such as Figure 4 As shown, semi-circular arc grooves are respectively opened on the outer wall of the inclined sliding block 35 and the inner wall of the inclined sliding groove 37, and springs are arranged inside the two semi-circular arc grooves. The springs push the linkage block 33 to reset. It should be pointed out that the structure and working principle of the spring are all existing technologies and will not be elaborated here.

[0030] As an embodiment provided by the utility model, preferably, the number of driving mechanisms 3 is several, and the several driving mechanisms 3 are distributed in a linear array inside the fixed seat 1. A positioning block 12 is fixedly installed on the outer wall at the top of the fixed seat 1. The number of positioning blocks 12 is also several, and the several positioning blocks 12 are distributed in a linear array on the top of the fixed seat 1, and each driving block 32 is located between every two positioning blocks 12, which can limit the movement direction of the linkage block 33 and the driving block 32.

[0031] As a specific embodiment provided by the utility model, Figure 5 As shown, the fixing seat 1 includes a positioning plate 13, a support column 14 and a fixing plate 15, and the fixing plate 15 and the positioning plate 13 are fixedly connected by the support column 14 and bolts.
