Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for ring processing, and more specifically to a mechanical unloader for automatic ring processing. Background Technology

[0002] Currently, the machining of tapered bearing rings mainly includes key processes such as turning, grinding, and heat treatment. Modern processes also widely adopt advanced methods such as CNC machining and cold rolling to improve precision and efficiency. Traditional machining mainly relies on manual clamping, but with the popularization of automation, loading and unloading can be accomplished by robotic arms and other mechanisms. Regarding existing mechanical unloading arms for rings, they use pneumatic chucks, which are suitable for small and medium-sized rings. However, for large-sized rings, there are no pneumatic chucks of the corresponding size, requiring customization, which is costly. Other unloading structures are needed to replace the mechanical chuck structure. Therefore, it is necessary to design a mechanical unloading arm with the above-mentioned functions. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a mechanical unloading hand for automatic ring processing. The mechanical unloading hand uses a receiving hopper instead of a gripper structure, which facilitates the receiving of rings of various sizes. At the same time, it uses a flipping baffle to realize the output of rings, which facilitates the transfer and transportation of rings during the ring processing.

[0004] A mechanical unloading hand for automatic ring processing includes an inclined rodless cylinder. A support plate is fixed to the slider of the rodless cylinder. An inclined unloading cylinder is fixed to the front face of the support plate. A pusher plate is fixed to the piston rod of the unloading cylinder.

The middle part of the flipping rod abuts against the front face of the receiving arm and is inserted with a T-shaped hinge pin. The hinge pin is inserted and fixed to the receiving arm. The upper end of the flipping rod is located to the lower right of the unloading cylinder and is directly opposite the pusher plate.

[0005] The receiving hopper is fixedly connected to a positioning pin at the end away from the lower end of the receiving arm, and a longitudinal connecting column is inserted and fixed at the lower end of the flipping rod. A spring is fixedly connected between the connecting column and the positioning pin.

[0006] Preferably, the tilting direction of the rodless cylinder, the tilting direction of the feeding cylinder, and the tilting direction of the receiving arm are the same, while the tilting direction of the guide plate at the bottom of the receiving hopper is opposite to the tilting direction of the feeding cylinder.

[0007] Preferably, the stroke of the feeding cylinder is greater than the distance between the upper end of the flipping rod and the pusher plate.

[0008] Preferably, the receiving arm and the discharging cylinder are parallel, and a connecting plate is fixedly connected to the lower end of the receiving arm, which is fixedly connected to the rear wall of the receiving hopper.

[0009] Preferably, the receiving arm has several sets of obliquely placed waist-shaped holes, and screws are inserted and fixed into the waist-shaped holes respectively, and the screws are screwed and fixed to the support plate; the receiving arm below the waist-shaped holes has weight-reducing grooves.

[0020] Example: See Figure 1 , 2 As shown, the mechanical unloading hand for automatic ring processing includes an inclined rodless cylinder 1. A support plate 2 is fixed to the slider of the rodless cylinder 1. An inclined unloading cylinder 3 is fixed to the front end face of the support plate 2. A pusher plate 12 is fixed to the piston rod of the unloading cylinder 3. An inclined receiving arm 4 is fixed to the support plate 2 below the unloading cylinder 3. A receiving hopper 5 is fixed to the lower end of the receiving arm 4. The upper end face of the receiving hopper 5 is formed with a receiving port 51, and the lower end is formed with an inclined guide plate 52. The left end of the guide plate 52 is formed with a discharge port 53; the discharge port 53 of the receiving hopper 5 is provided with a baffle plate 7. The upper end of the baffle plate 7 abuts against the right wall of the receiving hopper 5 above the discharge port 53 and is fixedly connected with an arc-shaped flipping rod 6. The middle part of the flipping rod 6 abuts against the front end face of the receiving arm 4 and is inserted with a T-shaped hinge pin 13. The hinge pin 13 is inserted and fixed on the receiving arm 4. The upper end of the flipping rod 6 is located to the lower right of the feeding cylinder 3 and is directly opposite the push plate 12.

[0021] The receiving hopper 5 is fixedly connected to a positioning pin 10 at the end away from the lower end of the receiving arm 4, and a longitudinal connecting column 8 is inserted and fixed at the lower end of the flipping rod 6. A spring 11 is fixedly connected between the connecting column 8 and the positioning pin 10.

[0022] The tilting direction of the rodless cylinder 1, the tilting direction of the feeding cylinder 3, and the tilting direction of the receiving arm 4 are the same, while the tilting direction of the guide plate 52 at the bottom of the receiving hopper 5 is opposite to the tilting direction of the feeding cylinder 3.

[0023] The stroke of the feeding cylinder 3 is greater than the distance between the upper end of the flipping rod 6 and the push plate 12, and the upper end of the flipping rod 6 is located within the stroke path of the feeding cylinder 3. When the piston rod of the feeding cylinder 3 extends, it will push the upper end of the flipping rod 6 to move, thereby causing the flipping rod 6 to rotate around the hinge pin 13, so that the baffle plate 7 moves away from the discharge port 53 of the receiving hopper 5.

[0024] The receiving arm 4 and the unloading cylinder 3 are parallel. A connecting plate 15 is fixedly connected to the lower end of the receiving arm 4. The connecting plate 15 is fixedly connected to the rear wall of the receiving hopper 5. The connecting plate 15 is used as a connecting plate and can be fixed together by bolts.

[0025] The receiving arm 4 has several sets of obliquely placed waist-shaped holes 41, and screws 14 are inserted and fixed in the waist-shaped holes 41 respectively. The screws 14 are screwed and fixed to the support plate 2. The receiving arm 4 on the lower side of the waist-shaped holes 41 has a weight-reducing groove 42, and the position of the receiving arm 4 can be adjusted.

[0026] See Figure 3 , 4 As shown, the rodless cylinder 1 is provided with a mounting bracket 9, and the rodless cylinder 1 is fixedly connected to the automatic ring processing equipment through the mounting bracket 9;

[0027] The mounting bracket 9 includes two sets of opposing clamps, each clamp including a rectangular slot 1. The opposing end faces of the slots 91 are formed with insertion ports. A connecting rod 92 is fixedly connected between the two sets of slots 91. A clamping plate 93 is inserted into the slot 91. A connecting sleeve 94 is fixedly connected to the middle of the end face of the clamping plate 93 facing away from the insertion port on the slot 91. A locking bolt 95 is inserted into the connecting sleeve 94 and screwed onto the slot 1. The upper end face of the slot 91 at the upper end of the mounting bracket 9 is formed... The upper ear seat and the lower groove seat 91 are fixed to the outer walls of both sides. The upper ear seat and the lower ear seat are respectively inserted into the mounting bolts, which are screwed and fixed to the automatic ring processing equipment. The rodless cylinder 1 in this application needs to be installed on the automatic ring processing equipment, so a corresponding mounting frame 9 needs to be designed. The mounting frame 9 has a simple structure and is easy to install. At the same time, the rodless cylinder 1 can be quickly installed and connected to the mounting frame 9, and the position of the rodless cylinder 1 can be finely adjusted.

[0028] The two ends of the rodless cylinder 1 are respectively inserted into the slot 91 and clamped and fixed between the clamping plates 93; the two sides of the clamping plates 93 respectively abut against the inner walls of the two sides of the slot 91, and the locking bolt 95 is screwed with a retaining nut 96, which presses against the slot 91 and prevents the slot 91 from loosening.

[0029] Working principle: This structure is a mechanical unloader used for automatic ring processing. Its structure is as follows: Figure 1 , 2 As shown, Figure 2 In the structure, an inclined conveying trough is provided on one side of the discharge port 53 of the receiving hopper 5. So when the feeding cylinder 3 is activated and the baffle plate 7 is driven to flip and move, the collar set in the receiving hopper 5 can roll and output along the guide bottom plate 52 and finally enter the conveying trough.

[0030] When material needs to be received, the rodless cylinder 1 is activated, which drives the receiving hopper 5 to move downward at an angle. After reaching the position, the ring falls into the receiving hopper 5. The unflipped baffle 7 prevents the ring from falling out of the receiving hopper 5. Then, the receiving hopper 5 is driven upward to raise the height of the ring, so that it has enough potential energy to move into the next automated processing equipment.

[0031] The embodiments described above are illustrative of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be as set forth in the claims.
