Technical Field

[0001] This invention belongs to the field of workpiece handling devices, and particularly relates to a workpiece loading and unloading device for a honing machine. Background Technology

[0002] During the honing process, the workpiece needs to be accurately transferred from the storage area to the machining station and removed after machining. Existing loading and unloading devices mostly use multi-axis robots, which are complex in structure and expensive. For workpieces with specific internal holes, such as cylinders, stable clamping and positioning are required during the transfer process. In addition, existing loading and unloading devices can usually only clamp one workpiece at a time, and the loading and unloading actions must be performed step by step. It is difficult to simultaneously complete the loading of the workpiece to be processed and the unloading of the processed workpiece, resulting in low workpiece turnover efficiency and affecting the overall machining cycle time. Summary of the Invention

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-12 This invention provides a technical solution for a workpiece loading and unloading device for a honing machine: A honing machine workpiece loading and unloading device comprises a cylinder placement seat 1, an upper transverse moving assembly 2, a lower transverse moving assembly 3, a front and rear reciprocating mechanism 4, a pin 5, a lower baffle plate 6, and a guide rail cover 7.

[0018] The base support 11 of the cylinder block mounting seat 1 is constructed by welding a bottom steel plate, a top steel plate, and a steel pipe. A mounting groove 14 is machined on the top steel plate, and the cylinder liner pressure ring 13 is placed in the mounting groove 14. The cylinder block mounting plate 12 is fixed above the top steel plate and is used to place the cylinder block to be processed. The lower part of the cylinder block is further supported by the cylinder liner pressure ring 13.

[0019] The mounting plate 21a of the upper transverse component 2 includes a base plate, two side plates, a motor mounting plate 211a, and a bearing seat pad 212a, used to securely mount the longitudinal moving mechanism 22a, the linear guide rail 23a, and the motor mechanism 24a. The first grinding pad 25 engages with the linear guide rail 23a via a slider, and a first movable lever 27 and a second movable lever 29 are fixed thereon. A fixed lever mounting plate 213 is connected to the outer side of one side plate of the mounting plate 21a, and the first fixed lever 26 and the second fixed lever 28 are respectively fixed to the mounting plate via fixed lever mounting seats 214. The motor mechanism 24a drives the ball screw 223a to rotate, and the screw nut seat 226a drives the first grinding pad 25 and the two movable levers to move linearly.

[0020] The lower transverse component 3 is also equipped with a longitudinal movement mechanism 22b and a motor mechanism 24b. Its lead screw nut seat 226b is connected to the second grinding pad 31 through the lead screw nut grinding pad plate 32. The second grinding pad 31 is set on the linear guide rail 23b of the lower transverse component 3 and is driven by the motor mechanism 24b to achieve longitudinal movement along the guide rail.

[0021] The reciprocating base 41 of the reciprocating mechanism 4 is welded together from a square frame base 411, two guide rail mounting seats 412, an inverted U-shaped blocking plate 413, and a cylinder mounting plate 414. The mounting plate 21b of the lower transverse component 3 is fixedly connected to the reciprocating base 41 by pins 5. Two guide rail mounting seats 412 are fixed to the upper end of the square frame base 411 of the reciprocating base 41. The guide rails are mounted on the guide rail mounting seats 412, and the guide rail seats 43 are slidably connected to the linear guide rails 44 on the lower transverse component 3. A cylinder mounting plate 414 is provided on the square frame base 411 between the two guide rail mounting seats 412. The U-shaped base 421 of the reciprocating cylinder assembly 42 and the cylinder stroke adjustment plate 422 are mounted on the cylinder mounting plate 414, and the magnetically coupled rodless cylinder 423 is placed inside the U-shaped base 421. When the rodless cylinder 423 is activated, since the mounting plate 21b of the lower transverse component 3 is fixed, the cylinder drives the reciprocating base 41 to slide back and forth along the linear guide rail 44, thereby driving all the levers on the upper transverse component 2 to move back and forth as a whole.

[0022] In addition, this device also includes a photoelectric sensor and a control system. The photoelectric sensor is installed on the workpiece inlet side of the cylinder placement seat 1 to detect whether the workpiece has been conveyed to a predetermined position by the roller conveyor; the control system is electrically connected to the photoelectric sensor, the motor mechanism 24a of the upper transverse component 2, the motor mechanism 24b of the lower transverse component 3, and the rodless cylinder 423 of the front and rear reciprocating mechanism 4, and is used to receive the detection signal from the photoelectric sensor and control each driving component to operate according to a preset program.

[0023] The device operates as follows: In the initial state, the upper horizontal movement component 2 is in the retracted position, the first movable lever 27 and the first fixed lever 26 are in the open state, and the second movable lever 29 and the second fixed lever 28 are in the open state.

[0024] The workpiece is conveyed to the cylinder placement seat 1 by the front roller conveyor. After the photoelectric sensor detects that the workpiece is in place, it sends a detection signal to the control system. The control system first drives the rodless cylinder 423 of the reciprocating cylinder assembly 42 to move forward to the position, which drives the upper transverse assembly 2 to move forward as a whole, so that each lever is close to both sides of the workpiece. Then, the control system starts the motor mechanism 24a of the upper transverse assembly 2 to rotate forward, driving the ball screw 223a to rotate. Through the screw nut seat 226a, the first grinding pad 25 moves along the linear guide rail 23a, so that the first movable lever 27 moves closer to the first fixed lever 26, and at the same time the second movable lever 29 moves closer to the second fixed lever 28. The first movable lever 27 and the first fixed lever 26 clamp the workpiece to be processed through the liner 30, and the second movable lever 29 and the second fixed lever 28 clamp the processed workpiece through the liner 30.

[0025] After the clamping action is completed, the control system starts the motor mechanism 24b of the lower transverse component 3. The second grinding pad 31 is driven to move laterally along the guide rail through the lead screw nut and grinding pad 32. The second grinding pad 31 pushes the clamped workpiece and the clamping mechanism to move laterally together, so as to transfer the workpiece to be processed to the processing station and at the same time transfer the processed workpiece to the unloading station.

[0026] Once in position, the motor mechanism 24a of the upper transverse component 2 reverses, driving the first movable lever 27 away from the first fixed lever 26 and the second movable lever 29 away from the second fixed lever 28, restoring the levers to their open state and releasing the workpiece. Subsequently, the rodless cylinder 423 of the reciprocating cylinder assembly 42 reverses, driving the entire upper transverse component 2 to retract and reset. Finally, the motor mechanism 24b of the lower transverse component 3 reverses, causing the second grinding pad 31 to move laterally back to the starting position, awaiting the next work cycle.

[0027] During the above process, the lower baffle plate 6 is fixed to the side of the upper transverse component 2 mounting plate 21a facing the cylinder placement seat 1, and extends downward to cover the lower transverse component 3 mounting plate 21b. The guide rail cover 7 is fixed to the side of the lower transverse component 3 mounting plate 21b facing the cylinder placement seat 1 and covers the linear guide rail 44. Both effectively prevent honing fluid, chips, etc. from entering the moving parts, ensuring long-term stable operation of the device.

[0028] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention within the scope of the technology disclosed in the present invention, and all such substitutions or changes should be covered within the scope of protection of the present invention.
