Description

Technical Field

[0001] This invention relates to the field of mechanical automation, specifically to a feeding device for irregularly shaped drum brake parts. Background Technology

[0002] Drum brakes are braking devices that use stationary brake pads inside a brake drum to rub against the brake drum as it rotates with the wheel, thereby generating friction to reduce the wheel's rotational speed.

[0003] The irregularly shaped parts of the drum brake assembly have the following structure: Figure 4 As shown, during the loading and positioning process, existing loading devices cannot properly correct and position drum brake parts that are tilted forward or backward, resulting in inconsistent clamping angles and affecting the accuracy of subsequent drum brake part positioning. Therefore, a new loading device for irregularly shaped drum brake parts is proposed to address the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a feeding device for irregularly shaped drum brake parts in order to solve the above-mentioned problems.

[0005] The present invention achieves the above-mentioned objective through the following technical solution: a drum brake irregular part feeding device, including an irregular part feeder, an irregular part adjusting seat, an irregular part tail end support mechanism, an irregular part front end setting mechanism, and a pneumatic clamp. The discharge end of the irregular part feeder and one end of the irregular part adjusting seat are connected to each other through a material handling slide. The irregular part adjusting seat is provided with the irregular part front end setting mechanism and the irregular part tail end support mechanism at its front and rear ends, respectively. The pneumatic clamp acts on the front end of the irregular part body. The tail end push cone in the tail end support mechanism of the irregular part moves upward and contacts the tail end hole on the body of the irregular part. The surface of the square plate in the front end adjustment mechanism of the irregular part contacts the bottom plane area of ​​the front end on the body of the irregular part, and electromagnetic push rods are connected to the four corners of the bottom of the square plate through ball head connectors. A horizontal detection module is installed in the middle of the bottom of the square plate.

[0006] In a further technical solution, the tail end support mechanism of the irregular part also includes a second cylinder. The output end of the second cylinder passes through a hole structure located at the front end of the material handling slide and is connected to the tail end push cone. The tail end push cone is located between two rectangular protrusions on one side of the top of the irregular part adjustment seat.

[0007] In a further technical solution, the front end adjustment mechanism of the irregular part also includes an electromagnet magnetic attraction area, a four-leaf plate and a first cylinder set on the square plate. The electromagnet magnetic attraction area magnetically attracts the front bottom plane area located on the body of the irregular part. The middle part of the four-leaf plate is connected to the output end of the first cylinder, and the four ends of the four-leaf plate are respectively fixedly connected to the bottom ends of four electromagnetic push rods.

[0008] In a further technical solution, the cylinder end of the first cylinder is fixedly connected to the bottom port of the square hole, and the square hole is opened on the other side of the top of the irregular part adjustment seat.

[0009] A further technical solution is that an end plate is installed at the front end of the irregular part adjustment seat, and an irregular part end positioning sensor is provided in the middle of one side of the end plate.

[0010] In a further technical solution, the pneumatic clamp moves back and forth between the top front end of the irregular part adjustment seat and the target workpiece of the irregular part assembly via a moving module.

[0011] A further technical solution is provided, wherein the mobile module includes a third cylinder, an L-shaped support plate, an L-shaped slide block, a fourth cylinder, a push-pull slide plate, and a motor. An L-shaped slide block is slidably mounted on two guide rails on the L-shaped support plate, and one side of the L-shaped slide block is connected to the output end of the third cylinder fixed on one side of the L-shaped support plate. A push-pull slide plate is slidably mounted on two guide rails on the L-shaped slide block, and the top of the push-pull slide plate is connected to the output end of the fourth cylinder located on the top of the L-shaped slide block. The motor shaft end located on one side of the push-pull slide plate is fixedly connected to the top of the pneumatic clamp.

[0012] In a further technical solution, the multiple irregularly shaped components within the material handling chute are arranged in a straight line.

[0013] In a further technical solution, the horizontal detection module and the four electromagnetic push rods are electrically connected to the same controller, and the controller is not limited to issuing a single program instruction to the electromagnetic push rods.

[0014] The invention differs from existing technologies in that: It can adjust and straighten the front and rear ends of the irregular part, avoiding the irregular part from tilting forward or backward, and providing a stable clamping state for the fixture. It has the structural function of horizontal correction and vertical tilt adjustment of the irregular part body after it has been aligned and positioned, which solves the problem that pneumatic clamps can only rotate in the horizontal plane and cannot adjust the state of the irregular part body a second time. It can meet the needs of inserting irregular parts body at different orientation positioning structures on the target workpiece. Attached Figure Description

[0022] Please see Figure 1-4As shown, a drum brake irregular part feeding device includes an irregular part feeder 1, an irregular part adjusting seat 3, an irregular part tail end support mechanism, an irregular part front end setting mechanism, and a pneumatic clamp 14. The discharge end of the irregular part feeder 1 and one end of the irregular part adjusting seat 3 are connected to each other through a material handling slide 2. The front end setting mechanism and the tail end support mechanism are respectively provided at the front and rear ends of the irregular part adjusting seat 3. The pneumatic clamp 14 acts on the front end of the irregular part body 6. The tail end push cone 5 in the tail end support mechanism of the irregular part moves upward and contacts the tail end hole 620 on the body of the irregular part 6. The surface of the square plate 340 in the front end adjustment mechanism of the irregular part contacts the front bottom plane area 610 on the body of the irregular part 6. The four corners of the bottom of the square plate 340 are connected to electromagnetic push rods 350 through ball head connectors 343. A horizontal detection module 342 is installed in the middle of the bottom of the square plate 340.

[0023] like Figure 2 As shown, the tail end support mechanism of the irregular part also includes a second cylinder 4. The output end of the second cylinder 4 passes through the hole structure located at the front end of the material handling slide 2 and is connected to the tail end push cone 5. The tail end push cone 5 is located between two rectangular protrusions 310 located on one side of the top of the irregular part adjustment seat 3.

[0024] like Figure 2 As shown, the front end adjustment mechanism of the irregular part also includes an electromagnet magnetic attraction area 341, a four-leaf plate 360 ​​and a first cylinder 370 disposed on the square plate 340. The electromagnet magnetic attraction area 341 magnetically attracts the front bottom plane area 610 located on the irregular part body 6. The middle part of the four-leaf plate 360 ​​is connected to the output end of the first cylinder 370, and the four ends of the four-leaf plate 360 ​​are respectively fixedly connected to the bottom ends of four electromagnetic push rods 350.

[0025] like Figure 2 As shown, the cylinder end of the first cylinder 370 is fixedly connected to the bottom port of the square hole 330, and the square hole 330 is opened on the other side of the top of the irregular part adjustment seat 3.

[0026] The front end of the irregular part adjustment seat 3 is equipped with an end plate 320, and an irregular part end positioning sensor is provided in the middle of one side of the end plate 320. The multiple irregular part bodies 6 in the material handling slide 2 are arranged in a straight line. The horizontal detection module 342 and the four electromagnetic push rods 350 are electrically connected to the same controller, and the controller is not limited to issuing a program instruction to the electromagnetic push rods 350.

[0027] like Figure 1As shown, the pneumatic clamp 14 reciprocates between the top front end of the irregular part adjustment seat 3 and the irregular part assembly target workpiece 15 via a moving module. The moving module includes a third cylinder 7, an L-shaped support plate 8, an L-shaped slide 10, a fourth cylinder 11, a push-pull slide plate 12, and a motor 13. The L-shaped slide 10 is slidably mounted on two guide rails 9 on the L-shaped support plate 8, and one side of the L-shaped slide 10 is connected to the output end of the third cylinder 7 fixed on one side of the L-shaped support plate 8. The push-pull slide plate 12 is slidably mounted on two guide rails 9 on the L-shaped slide 10, and the top end of the push-pull slide plate 12 is connected to the output end of the fourth cylinder 11 located on the top of the L-shaped slide 10. The shaft end of the motor 13 located on one side of the push-pull slide plate 12 is fixedly connected to the top end of the pneumatic clamp 14.

[0028] Working principle: The irregular part feeding machine 1 arranges each irregular part body 6 in a line on the material handling slide 2. When the irregular part body 6 located at the leftmost end is in place at the irregular part adjusting seat 3, the irregular part end positioning sensor located on the end top plate 320 detects that the irregular part body 6 is in place. The second cylinder 4 extends and inserts the tail end pushing cone 5 connected to it into the tail end hole 620, so that the tail end of the irregular part body 6 is raised to a horizontal state. At the same time, the front bottom plane area 610 is also adjusted from an inclined state to a horizontal state, so that the front bottom plane area 610 is in full contact with the surface of the square plate 340. At this time, the electromagnet magnetic attraction area 341 magnetically attracts and fixes the front bottom plane area 610. The first cylinder 370 runs to move the square plate 340 and the magnetically fixed irregular part body 6 away from the square hole 330, and the tail end hole 620 is separated from the tail end pushing cone 5. If the horizontal detection module 342 detects that the square plate 340 and the magnetically fixed irregular part body 6 have not reached the set placement angle position, the horizontal detection module 342 transmits the detection data to the controller for processing and analysis according to the set angle position parameters. The controller issues commands to the four electromagnetic push rods 350 to operate. The four electromagnetic push rods 350 extend and retract to adjust the square plate 340 to the set placement angle position. At this time, the moving module moves the connected motor 13 and pneumatic clamp 14 to the front end of the irregular part body 6. At the same time, the pneumatic clamp 14 is driven by the motor 13 to adjust the clamping position to clamp the front end of the irregular part body 6. The bottom plane area 610 of the front end is no longer magnetically constrained by the electromagnet magnetic attraction area 341. Finally, the pneumatic clamp 14 is moved by the moving module to the irregular part assembly target workpiece 15.

[0029] The invention differs from existing technologies in that: It can adjust and straighten the front and rear ends of the irregular part body 6, avoiding the irregular part body 6 tilting forward and backward, and providing a stable clamping state for the fixture. It has the structural function of horizontal correction and vertical tilt adjustment of the irregular part body 6 after it has been aligned and positioned, which solves the problem that the pneumatic clamp 14 can only rotate in the horizontal plane and cannot adjust the state of the irregular part body 6 a second time. It can meet the needs of inserting the irregular part body 6 into the positioning structure of different orientations on the target workpiece 15 of the irregular part assembly.
