Description

Technical Field

[0001] The utility model relates to the technical field of coupling processing, in particular to a coupling processing positioning mechanism. Background Art

[0002] A coupling is a device that connects two shafts, or a shaft and a rotating part, so that they rotate together during motion and power transmission and do not disengage under normal circumstances. To ensure the quality of the coupling, it needs to be fixed and positioned during processing.

[0003] Most existing coupling processing and positioning mechanisms can only position couplings of one size, and have poor results when positioning couplings of different lengths or sizes, resulting in a limited scope of application of the mechanism. Utility Model Content

[0004] The purpose of the utility model is to solve the disadvantage in the prior art that the existing coupling machining and positioning mechanism cannot position couplings of different lengths or sizes, and to propose a coupling machining and positioning mechanism.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A coupling processing positioning mechanism includes a base plate, the top of the base plate is fixedly connected to two support plates, a bidirectional screw rod is rotatably inserted between the two support plates, and the outer wall thread sleeve of the bidirectional screw rod is provided with two slides, the top of the slide rod is fixedly connected to a first electric push rod, the outer wall of one end of the first electric push rod is fixedly connected to a mounting plate, one side of the mounting plate is rotatably connected to multiple positioning blocks, one end of the first electric push rod is fixedly connected to the mounting block, multiple sides of the mounting block are rotatably connected to connecting rods, the other end of the connecting rod is rotatably connected to the positioning block, one side of the slide rod is fixed with a second electric push rod by a bolt, and one end of the second electric push rod is fixedly connected to a pressure plate.

[0007] Furthermore, a plurality of through holes are provided on the top of the bottom plate.

[0008] Furthermore, a first guide rod is fixedly connected between the two support plates, and the slide plate is slidably sleeved on the first guide rod.

[0009] Furthermore, a motor is fixedly connected to the top of the base plate, and an output end of the motor is fixedly connected to one end of a bidirectional lead screw.

[0010] Furthermore, a second guide rod is fixedly connected to one side of the slide plate, and the pressure plate is slidably sleeved with the second guide rod.

[0011] Furthermore, a wear-resistant pad is bonded to the outer wall of the positioning block.

[0012] Furthermore, a through hole is provided on one side of the pressing plate, and a plurality of positioning blocks pass through the through hole.

[0013] The beneficial effects of the utility model are:

[0014] 1. The bidirectional screw is rotated by the motor, thereby driving the slide to move, thereby adjusting the distance between the positioning blocks of the two mounting plates to accommodate couplings of different lengths.

[0015] 2. By stretching the first electric push rod, the plurality of positioning blocks are opened outward, thereby tensioning the coupling from the inside and then fixing the coupling, thereby facilitating the use of couplings of different sizes.

[0016] 3. By moving the lower pressure plate driven by the second electric push rod, the coupling is clamped from both ends, thereby further fixing the coupling and improving the fixing effect of the coupling. BRIEF DESCRIPTION OF THE DRAWINGS

A motor 14 is fixed to the top of the base plate 1 by bolts, and the output end of the motor 14 is fixedly connected to one end of the bidirectional screw rod 3. Driven by the motor 14, the bidirectional screw rod 3 rotates, thereby driving the slide plate 4 to move, thereby making the distance between the positioning blocks 7 between the two mounting plates 6 suitable for use with couplings of different lengths. The top of the slide plate 4 is fixed with a first electric push rod 5 by bolts, and the outer wall of one end of the first electric push rod 5 is fixed with a A mounting plate 6 is rotatably connected to one side of the mounting plate 6 with multiple positioning blocks 7. Under the tension of the first electric push rod 5, the multiple positioning blocks 7 are opened outward, thereby tensioning the coupling from the inside, and then fixing the coupling. A mounting block 8 is welded to one end of the first electric push rod 5, and multiple sides of the mounting block 8 are rotatably connected to connecting rods 9. The other end of the connecting rod 9 is rotatably connected to the positioning block 7. A second electric push rod 10 is fixed to one side of the slide plate 4 by bolts, and a pressure plate 11 is fixed to one end of the second electric push rod 10 by bolts. The pressure plate 11 moves under the drive of the second electric push rod 10, thereby clamping from both ends of the coupling, and further fixing the coupling.

[0023] A plurality of through holes 12 are provided on the top of the base plate 1, and the base plate 1 is fixed through the through holes 12. A first guide rod 13 is welded between the two support plates 2, and the slide plate 4 is slidably sleeved with the first guide rod 13, and the movement of the slide plate 4 is guided by the first guide rod 13. A second guide rod 15 is welded on one side of the slide plate 4, and the pressure plate 11 is slidably sleeved with the second guide rod 15, and the movement of the pressure plate 11 is guided by the second guide rod 15, thereby improving the stability of the coupling clamping. A wear-resistant pad 16 is bonded to the outer wall of the positioning block 7, and the wear-resistant pad 16 reduces the wear of the positioning block 7. A through hole is provided on one side of the pressure plate 11, and a plurality of positioning blocks 7 pass through the through hole.

[0024] Working principle: When in use, first, the mounting block 8 is driven to move under the contraction of the first electric push rod 5, thereby pulling the connecting rod 9 to make the multiple positioning blocks 7 gather to the middle, and then, the coupling is placed between the two mounting plates 6, and then, the bidirectional screw 3 is rotated under the drive of the motor 14, thereby driving the slide plate 4 to move along the first guide rod 13, and then the positioning blocks 7 of the two mounting plates 6 are plugged into the two ends of the coupling, and then, under the stretching of the first electric push rod 5, the multiple positioning blocks 7 are opened outward, thereby tensioning from the inside of the coupling, and then fixing the coupling, and then, the lower pressure plate 11 is moved under the drive of the second electric push rod 10, thereby clamping from both ends of the coupling, and then further fixing the coupling.
