Technical Field

[0001] The present application relates to the field of hook-type motors, and more particularly to a hook-type cylinder and a manual release device for a wiring harness. Background Art

[0002] Hook cylinder is a type of cylinder with a specific structure and function. The end or specific part of the cylinder piston rod has a hook-shaped structure, which enables the cylinder to fix objects like a hook when performing an action. Hook cylinders usually have the characteristics of compact structure and flexible action, and can adapt to various complex working environments. Therefore, hook cylinders play an important role in industrial automation and mechanical equipment.

[0003] In the related technology, during the wire harness detection process, operators often use a hook cylinder. The operator first installs the hook cylinder to the appropriate position, and then places the wire harness on the end of the hook cylinder piston rod. The hook cylinder limits the position of the wire harness, thereby improving the stability of the wire harness during the detection process.

[0004] In view of the above-mentioned related technologies, the inventor believes that when the hook cylinder restricts the position of the wiring harness, the end of the hook cylinder piston rod can only release the wiring harness uniformly through cylinder exhaust, and the extension length of the cylinder piston rod cannot be adjusted to manually release the wiring harness. Summary of the invention

[0008] By adopting the above technical solution, when the operator wants to manually release the wiring harness restricted by the limit column, the operator moves the operating column toward the base, the movement of the operating column drives the cylinder body to move, and the cylinder body drives the limit column to move, thereby releasing the restriction of the limit column on the wiring harness, making it convenient for the operator to manually release the wiring harness. At this time, the first spring is in a compressed state. When the operator takes out the wiring harness and releases the operating column, the cylinder body is reset under the elastic force of the first spring. The guide rod is set to provide guidance for the movement of the cylinder body.

At this time, the operator inflates the first airbag through the inflation nozzle, and the length of the telescopic column extended out of the cylinder body by the first airbag will change, thereby facilitating the operator to accurately adjust the moving distance of the cylinder body and the limit column.

[0018] By adopting the above technical solution, when the first airbag pushes the telescopic column to extend out of the cylinder body, the telescopic column drives the fixed block to move, and the fixed block makes the third spring in a compressed state. When the operator performs the deflation operation, the fixed block moves under the action of the third spring, and the fixed block drives the telescopic column to reset.

When the operator releases the operating column, the fourth spring makes the rack close to the guide rod. At this time, when the rack enters the connecting groove again, the rack is plugged into the connecting groove to fix the position of the cylinder body.

The setting of the guide rods 11 provides guidance for the movement of the cylinder body 2, and the cooperation between the limit disk 12 and the limit groove 13 is conducive to preventing the cylinder body 2 from separating from the guide rods 11.

[0044] Reference Figure 1 , Figure 2 A limiting column 15 for limiting the wiring harness is installed on the side of the cylinder body 2 away from the base 1, and an operating column 16 is installed on the side of the cylinder body 2. The operating column 16 is fixedly connected to the cylinder body 2, and an inclined surface is provided at the end of the limiting column 15 away from the base 1. The setting of the inclined surface of the limiting column 15 facilitates the wiring harness to drive the limiting column 15 and the cylinder body 2 to move, which is beneficial for the operator to install the wiring harness.

[0045] Reference Figure 3 A telescopic column 21 is slidably penetrated in the cylinder body 2, and a mounting groove 22 for slidingly cooperating with the telescopic column 21 is provided in the cylinder body 2. A reset assembly 3 for resetting the telescopic column 21 is provided in the cylinder body 2, and the reset assembly 3 includes a fixed block 31 and a third spring 32, and the fixed block 31 is fixedly connected to the telescopic column 21. A reset groove 33 for slidingly cooperating with the fixed block 31 is provided on the inner bottom surface of the mounting groove 22, one end of the third spring 32 is fixedly connected to the fixed block 31, and the other end of the third spring 32 is fixedly connected to the inner end surface of the reset groove 33.

[0046] Reference Figure 3 The cylinder body 2 is provided with an airbag assembly 4 for driving the telescopic column 21 to move, and the airbag assembly 4 includes a mounting frame 41, a first airbag 42, and a second airbag 43.

The second airbag 43 is arranged on the side of the mounting frame 41 close to the base 1, and the end of the second airbag 43 away from the mounting frame 41 is fixedly connected to the inner end surface of the mounting groove 22. The first airbag 42 is connected to the second airbag 43, and the mounting frame 41 is equipped with a solenoid valve for separating the first airbag 42 and the second airbag 43. The cylinder body 2 is equipped with an air filling nozzle 23 for air supply, and the air filling nozzle 23 is connected to the first airbag 42.

[0048] The implementation principle of the first embodiment of the present application is: when the operator closes the solenoid valve and inflates the first airbag 42 through the inflation nozzle 23, the first airbag 42 pushes the telescopic column 21 to extend out of the cylinder body 2. When the telescopic column 21 abuts against other objects, the telescopic column 21 causes the cylinder body 2 to move a certain distance toward the base 1, and the cylinder body 2 drives the limit column 15 to move a certain distance.

[0049] When the operator opens the solenoid valve and inflates the first airbag 42 through the inflation nozzle 23, the first airbag 42 and the second airbag 43 expand synchronously, so that the cylinder body 2 is closer to the base 1. The setting of the airbag assembly 4 facilitates the operator to adjust the moving distance of the cylinder body 2 and the limit column 15.

[0050] When the telescopic column 21 extends out of the cylinder body 2, the telescopic column 21 causes the fixed block 31 and the cylinder body 2 to move, the fixed block 31 causes the third spring 32 to be in a compressed state, and the cylinder body 2 causes the first spring 14 to be in a compressed state. After the operator deflates the cylinder body 2, the cylinder body 2 is reset under the elastic force of the first spring 14, the fixed block 31 moves under the action of the third spring 32, and the fixed block 31 drives the telescopic column 21 to reset.

[0051] Embodiment 2

[0052] The difference between the second embodiment and the first embodiment is that the cylinder body 2 is provided with an adjustment component 5 for adjusting the position of the dovetail block 44. Figure 4 The adjustment assembly 5 includes a dovetail bar 51, a screw rod 52 and a knob 53. The dovetail bar 51 is located in the dovetail groove 54, and the dovetail bar 51 is slidably matched with the inner side wall of the dovetail groove 54, and the dovetail bar 51 is attached to and tightly pressed against the dovetail block 44. The screw rod 52 is horizontally penetrated through the cylinder body 2 and is rotatably connected to the cylinder body 2. One end of the screw rod 52 penetrates the dovetail bar 51 and is threadedly matched with the dovetail bar 51. The other end of the screw rod 52 extends out of the cylinder body 2. The knob 53 is fixedly connected to the end of the screw rod 52 located outside the cylinder body 2.

[0053] The implementation principle of the second embodiment of the present application is: the operator rotates the knob 53, the knob 53 rotates to drive the screw rod 52 to rotate, the screw rod 52 rotates to move the dovetail bar 51, and the dovetail bar 51 moves to move the dovetail block 44, thereby facilitating the operator to adjust the position of the mounting frame 41 and the first airbag 42. At this time, when the operator closes the solenoid valve and inflates the first airbag 42 through the inflation nozzle 23, the length of the telescopic column 21 extended out of the cylinder body 2 by the first airbag 42 will change. When the telescopic column 21 abuts against other objects, the telescopic column 21 causes the cylinder body 2 to move toward the base 1, and the cylinder body 2 drives the limit column 15 to move, ultimately enabling the operator to accurately adjust the moving distance of the cylinder body 2 and the limit column 15, and facilitating the operator to release the wiring harness.

[0054] Embodiment 3

[0055] The difference between the third embodiment and the first embodiment is that the operating column 16 is rotatably matched with the cylinder body 2, and a connecting component is provided in the cylinder body 2. Figure 5 , the connecting assembly includes a rack 61, a fourth spring 62 and a rotating gear 63. The rack 61 is vertically inserted into the cylinder body 2, and the rack 61 is slidably matched with the cylinder body 2.

A plurality of connecting grooves 64 are provided, and the plurality of connecting grooves 64 are arranged at intervals along the length direction of the guide rod 11. An inclined surface is provided at the end of the rack 61 away from the fourth spring 62, and an inclined surface is provided at the end of the connecting groove 64 close to the base 1, and the rack 61 matches the inclined surface of the connecting groove 64.

[0057] The implementation principle of the third embodiment of the present application is as follows: when the operator moves the operating column 16 to move the cylinder body 2 and the limiting column 15 toward the base 1, the rack 61 cooperates with the inclined surface of the connecting groove 64 so that the connecting groove 64 does not hinder the movement of the cylinder body 2. When the operator releases the operating column 16, the fourth spring 62 makes the rack 61 close to the guide rod 11. At this time, when the rack 61 enters the connecting groove 64 again, the rack 61 and the connecting groove 64 are plugged and matched, thereby fixing the position of the cylinder body 2. When the operator rotates the operating column 16, the operating column 16 drives the rotating gear 63 to rotate, and the rotating gear 63 causes the rack 61 to rise, thereby releasing the locked state of the cylinder body 2, and realizing the reset of the cylinder body 2 and the limiting column 15.

[0058] Embodiment 4

[0059] The difference between the fourth embodiment and the third embodiment lies in the sliding fit between the operating column 16 and the cylinder body 2 and the connection assembly.

The lifting plate 73 is arranged on the side of the pressing rod 71 close to the operating column 16, and the lifting plate 73 is fixedly connected to the pressing rod 71.

[0060] Reference Figure 6 A driving block 74 is fixedly connected to the end of the operating column 16 near the push rod 71. The driving block 74 is provided with an inclined surface for cooperating with the lifting plate 73.

The plurality of retaining rings 77 are arranged at intervals along the length direction of the guide rod 11, and an inclined surface for cooperating with the retaining ring 77 is provided on the bottom of the push rod 71 near the side of the base 1.

[0061] The implementation principle of the fourth embodiment of the present application is as follows: when the operating column 16 drives the cylinder body 2 and the limiting column 15 to move toward the base 1, the inclined surface of the pressing rod 71 makes the connecting ring 77 not hinder the movement of the cylinder body 2. When the operator releases the operating column 16, the fifth spring 72 makes the pressing rod 71 close to the guide rod 11, and the blocking ring 77 limits the movement of the pressing rod 71, thereby fixing the position of the cylinder body 2. When the operator presses the operating column 16 toward the cylinder body 2, the movement of the operating column 16 drives the driving block 74 to move, and the driving block 74 cooperates with the lifting plate 73 through the inclined surface to make the pressing rod 71 rise, thereby releasing the locked state of the cylinder body 2, and realizing the reset of the cylinder body 2 and the limiting column 15.
