[0043] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 This application will be described in further detail.

[0044] Example 1

[0045] This embodiment discloses a shaft disc clamping fixture 5 for clamping shaft disc-type workpieces 7, as shown in the attached figure. Figure 1 Appendix Figure 2 and appendix Figure 3 As shown, the assembly includes a mounting platform 53, a locking block 51, a connecting device 52, and a driving device. The connecting device 52 connects the locking block 51 and the mounting platform 53. The locking block 51 is used to engage with the annular hole 71 of the workpiece 7. The locking block 51 is cylindrical in shape. During the production process of the locking block 51, the outer circumferential surface of the locking block 51 is treated with a friction texture to enhance the connection effect between the locking block 51 and the workpiece 7. The top surface of the mounting platform 53 is a support surface 531. After the locking block 51 is connected to the mounting platform 53 through the connecting device 52, both the locking block 51 and the lower end face of the workpiece 7 abut against the support surface 531. The mounting platform 53 provides support for the locking block 51 and the workpiece 7.

[0046] For the connecting device 52, two groups of identical connecting mechanisms are included, for the convenience of distinguishing the description, the two groups of connecting mechanisms are respectively called the first connecting mechanism and the second connecting mechanism, the first connecting mechanism is fixedly arranged on the upper end surface of the clamping block 51, and the second connecting mechanism is fixedly arranged on the lower end surface of the clamping block 51. Specifically, the first connecting mechanism and the second connecting mechanism each include a latch 521 and an anti-disengagement block 522, in the embodiment, the latch 521 is coaxially fixedly arranged with the clamping block 51, the anti-disengagement block 522 is fixedly arranged on the outer circumferential side surface of the latch 521, and two anti-disengagement blocks 522 are fixedly arranged on the same latch 521, and the two anti-disengagement blocks 522 are symmetrically arranged with the central axis of the latch 521.

[0047] The clamping block 51, the latch 521 and the anti-disengagement block 522 can be integrally formed, the outer surfaces of the latch 521 and the anti-disengagement block 522 can be treated as frictional surfaces, in addition, in the process of clamping the clamping block 51 to the ring hole 71, in order to avoid the interference of the latch 521 and the anti-disengagement block 522 to the clamping process, on the axial projection of the clamping block 51, the anti-disengagement block 522 does not exceed the edge of the clamping block 51.

[0048] The support surface 531 of the mounting table 53 is provided with a plug hole 532 and an anti-disengagement groove 533, the anti-disengagement groove 533 is in communication with the plug hole 532, in the embodiment, the anti-disengagement groove 533 is provided with two anti-disengagement grooves and is symmetrically arranged with the central axis of the plug hole 532. When the latch 521 is inserted into the plug hole 532, the two anti-disengagement blocks 522 can be correspondingly clamped into the two anti-disengagement grooves 533, the connection between the latch 521 and the mounting table 53 is mainly through friction, and the anti-disengagement groove 533 can limit the movement of the anti-disengagement block 522 along the plug-in direction of the latch 521, that is, it can limit the latch 521 from disengaging upwardly from the plug hole 532, thereby enhancing the anti-disengagement effect.

[0049] For the driving device, including the dismounting mechanism and the rotating mechanism, the dismounting mechanism can drive the mounting table 53 and the connecting mechanism to approach or move away from each other, so that the latch 521 can be inserted into or separated from the insertion hole 532, realizing the connection or separation of the connecting mechanism and the mounting table 53; the rotating mechanism is used to drive the clamping block 51 and the workpiece 7 to rotate, switching the connecting mechanism connected with the mounting table 53, i.e. the first connecting mechanism and the second connecting mechanism switching position. Specifically, at the beginning, the latch 521 in the second connecting mechanism is located in the insertion hole 532 and connected with the mounting table 53, at this time the lower end surface of the workpiece 7 abuts on the supporting surface 531, and the upper end surface of the workpiece 7 can be processed, when the upper end surface of the workpiece 7 is processed, the workpiece 7 needs to be turned over, at this time the dismounting mechanism is driven to move the mounting table 53 downward, overcoming the connection of the latch 521 and the insertion hole 532 and the connection of the anti-disengagement block 522 and the anti-disengagement groove 533, separating the second connecting mechanism from the mounting table 53, and then rotating the workpiece 7 and the clamping block 51 through the rotating mechanism to turn over, at this time the first connecting mechanism is located below, finally the mounting table 53 is driven upward by the dismounting mechanism and the latch 521 and the anti-disengagement block 522 in the first connecting mechanism are inserted into the insertion hole 532 and the anti-disengagement groove 533 respectively for connection, without manually disassembling and clamping the workpiece 7 again, improving the production and processing efficiency.

[0050] For the anti-disengagement groove 533, as shown in the accompanying drawings, Figure 4 The anti-disengagement groove 533 in the embodiment is inclined from top to bottom, during the process of inserting the latch 521 into the insertion hole 532 and the anti-disengagement block 522 into the anti-disengagement groove 533, due to the inclined setting of the anti-disengagement groove 533, the workpiece 7 and the clamping block 51 will rotate relative to the mounting table 53, the rotation axis is the central axis of the insertion hole 532, when the latch 521 and the anti-disengagement block 522 are inserted into the bottom of the insertion hole 532 and the anti-disengagement groove 533 respectively, the friction between the latch 521 and the mounting table 53 is the largest, the connection effect is the best, and the inclined angle of the anti-disengagement groove 533 is preferably 45°.

[0051] After the latch 521 and the anti-disengagement block 522 are connected with the insertion hole 532 and the anti-disengagement groove 533 respectively, when the mounting table 53, the workpiece 7 or the clamping block 51 is subjected to a force in the vertical direction (except the force for driving the mounting table 53 and the connecting mechanism to separate by the dismounting mechanism), the force can drive the latch 521 and the insertion hole 532 to separate, due to the limiting effect of the inclined anti-disengagement groove 533 on the anti-disengagement block 522 in the vertical direction, the latch 521 and the insertion hole 532 are difficult to separate easily.

[0052] For the disassembly mechanism, including the jacking assembly and clamping assembly, wherein the jacking assembly includes a jacking cylinder 561, and the mounting table 53 is installed on the output end of the jacking cylinder 561, and the clamping assembly includes a clamping cylinder 542, and an elastic clamp block 544 is installed on the output end of the clamping cylinder 542 and used for clamping the workpiece 7. The jacking cylinder 561 drives the mounting table 53 to vertically ascend and descend, and the clamping assembly is symmetrically provided with two groups, and the elastic clamp block 544 is driven by the clamping cylinder 542 to move and radially clamp the workpiece 7. The elastic clamp block 544 has a certain elasticity and will have a certain elastic deformation when it extrudes the workpiece 7, so as to increase the contact area and thus improve the clamping effect and reduce the clamping wear of the workpiece 7.

[0053] In addition, the clamping assembly further includes an electric guide rail 543, the electric guide rail 543 is fixed on the output end of the clamping cylinder 542, the elastic clamp block 544 is slidably connected to the electric guide rail 543 and is driven by the electric guide rail 543, and the electric guide rail 543 can drive the elastic clamp block 544 to rotate around the central axis of the insertion hole 532. When the jacking assembly drives the mounting table 53 to descend for separation, the electric guide rail 543 drives the elastic clamp block 544 to move, so as to drive the workpiece 7 and the clamping block 51 to rotate, and the insertion pin 521 rotates in the insertion hole 532, so that the anti-disengagement block 522 can just rise along the inclined anti-disengagement groove 533, and the anti-disengagement groove 533 will not limit the movement of the anti-disengagement block 522.

[0054] For the rotating mechanism, including a rotating motor 541, the clamping cylinder 542 is fixedly installed on the output shaft of the rotating motor 541, and the moving direction of the elastic clamp block 544 driven by the clamping cylinder 542 is parallel to the rotation axis of the output shaft of the rotating motor 541. After the clamping block 51, the workpiece 7 and the mounting table 53 are separated, the clamping block 51 and the workpiece 7 are turned over by the rotating motor 541, so as to switch the first connecting mechanism and the second connecting mechanism.

[0055] In addition, the driving device further includes an angle adjusting mechanism, the angle adjusting mechanism includes an adjusting motor 551 and a rotating shaft 552 connected to the output shaft of the adjusting motor 551, one end of the rotating shaft 552 away from the adjusting motor 551 is fixedly connected to the mounting table 53, the output end of the jacking cylinder 561 is fixedly connected with a lifting block 562, and the adjusting motor 551 is fixed on the lifting block 562. The mounting table 53 is driven to rotate by the adjusting motor 551 through the rotating shaft 552. When the clamping block 51 and the workpiece 7 are installed on the mounting table 53, the angle between the axis of the workpiece 7 and the vertical direction can be adjusted, so as to adapt to more drilling processes, and different inclined holes can be processed according to the processing requirements.

[0056] Embodiment Two

[0057] The difference from the embodiment one is that, as shown in the accompanying drawings Figure 5As shown, the anti-falling groove 533 includes a vertical groove 5331 and a limiting groove 5332, both of which are in communication with the insertion hole 532. The vertical groove 5331 is opened along the depth direction of the insertion hole 532 and has an opening on the support surface 531 for the anti-falling block 522 to be clamped into. The limiting groove 5332 is in communication with the vertical groove 5331 on the side away from the support surface 531 and is arranged at an angle with the vertical groove 5331.

[0058] In this embodiment, the vertical groove 5331 is opened along the up-down direction, and the limiting groove 5332 is opened along the horizontal direction, i.e., the limiting groove 5332 is arranged at an angle of 90° with the vertical groove 5331. When the anti-falling block 522 moves in the vertical groove 5331, it is smoother than the anti-falling groove 533 which is entirely inclined. After the anti-falling block 522 is clamped into the bottom of the vertical groove 5331, the elastic clamping block 544 is driven to move by the electric guide rail 543, thereby driving the workpiece 7 and the clamping block 51 to rotate, and thereby driving the anti-falling block 522 to be clamped into the anti-falling groove 533. At this time, the anti-falling block 522 will not move in the vertical direction, achieving a complete limiting effect.

[0059] When it is necessary to separate the mounting table 53 from the clamping block 51 and the workpiece 7, the elastic clamping block 544 is first driven by the electric guide rail 543 to drive the workpiece 7 and the clamping block 51 to rotate, and then the anti-falling block 522 is slid into the vertical groove 5331 from the anti-falling groove 533, and then the mounting table 53 is separated from the clamping block 51 and the workpiece 7 by the driving of the jacking assembly. Compared with the first embodiment, the anti-falling effect is better, but the step sequence is single when separating, and the anti-falling block 522 must be first slid into the vertical groove 5331 by the electric guide rail 543, and then the jacking assembly is driven to separate, which is low in separation efficiency.

[0060] Embodiment Three

[0061] As shown in the accompanying drawings, Figure 6 Compared with the first embodiment, the vertical groove 5331 is provided in this embodiment, and the anti-falling block 522 moves more smoothly in the vertical groove 5331 when it is just clamped into the vertical groove 5331. Compared with the second embodiment, the limiting groove 5332 is downwardly inclined in this embodiment, and the separation is realized quickly by the driving cooperation of the electric guide rail 543 and the jacking assembly.

[0065] Specifically, two mounting frames 57 are fixedly arranged on the rotating disc 6, and the two mounting frames 57 are symmetrically arranged with the central axis of the rotating disc 6. The jacking cylinder 561 and the rotating motor 541 are fixed on the mounting frame 57, and the lifting block 562 is slidingly connected with the mounting frame 57.
