[0023] See also Figure 1-2 , is a horizontal honing machine of this embodiment, used for processing a workpiece 100, wherein the horizontal honing machine comprises: The discharging mechanism 1 comprises a material collecting box 11, a material loading inclined wedge 12, a material loading lifting cylinder 13, and a guide plate 14. The material collecting box 11 is used to place a plurality of stacked workpieces 100. The material loading inclined wedge 12 is arranged at the downstream end of the material collecting box 11. The material loading inclined wedge 12 has an inclined surface inclined toward the downstream end. The output end of the material loading lifting cylinder 13 is connected to the material loading inclined wedge 12. The material loading lifting cylinder 13 is used to lift the material loading inclined wedge 12. The guide plate 14 is installed at the downstream end of the material loading inclined wedge 12. The guide plate 14 has an inclined surface inclined toward the downstream end. A honing head 2 extending along a first direction; The feeding mechanism 3 includes a bracket 31, a bracket cylinder 32, a bracket carrier 33, and a discharge wedge plate 34. The bracket 31 has a connected downhill section and an uphill section. The upstream end of the downhill section is connected to the downstream end of the guide plate 14. The output end of the bracket cylinder 32 is connected to the bracket 31. The bracket cylinder 32 is used to lift the bracket 31 and make reciprocating motions perpendicular to the first direction. The bracket 31 is installed on the top of the bracket carrier 33. The bracket carrier 33 is used to drive the bracket 31 to reciprocate in parallel to the first direction. The discharge wedge plate 34 has an inclined surface inclined toward the downstream end. The discharge wedge plate 34 has a protruding baffle 341 at the downhill section of the bracket 31. The upstream end of the baffle 341 faces the downstream end of the guide plate 14. The baffle 341 is used to limit the workpiece 100 when the bracket 31 is not lifted. The positioning mechanism 4 is used to clamp and fix the workpiece 100 when the workpiece 100 is lifted by the bracket 31 to be coaxial with the first direction; The material receiving mechanism 5 includes a material receiving box 51, which is connected to the downstream end of the unloading inclined wedge plate 34, and is used to place the processed workpiece 100; When the workpiece 100 falls to a position between the downslope section and the upslope section of the bracket 31 , the workpiece 100 is parallel to the first direction.

[0024] Through the above structure, when in use, the operator only needs to place a preset number of multiple workpieces 100 in the collection box 11 of the discharge mechanism 1. It is worth noting that the placement direction of the multiple workpieces 100 must be consistent, preferably parallel to the first direction, and then, the feeding lifting cylinder 13 of the discharge mechanism 1 is started to drive the feeding inclined wedge 12 to lift up, so that a workpiece 100 at the upper position is lifted, and the downstream end of the collection box 11 has a certain threshold height, which can limit the rolling out of the workpiece 100, but after the feeding After the workpiece 100 is lifted by the inclined wedge 12, the workpiece 100 passes over the threshold of the collecting box 11 and rolls downstream. Under the action of its own weight, the workpiece 100 rolls to the position of the unloading inclined wedge plate 34 of the feeding mechanism 3, and is limited by the baffle 341 and cannot continue to roll. Then, the bracket 31 is lifted under the action of the bracket cylinder 32, and the workpiece 100 limited by the baffle 341 is gradually lifted, so that the workpiece 100 finally breaks away from the baffle 341 of the unloading inclined wedge plate 34 and rolls to the position between the downhill section and the uphill section of the bracket 31. The bracket 31 further lifts the workpiece 100 until the axial height of the workpiece 100 reaches the same axis as the honing head 2, that is, the two extend in the first direction, and then the bracket carrier 33 starts to operate, so that the workpiece 100 enters the processing area of ​​the honing head 2 along the first direction under the support of the bracket 31, so that the honing head 2 is inserted into the pipe of the workpiece 100, and then the positioning mechanism 4 clamps and fixes the workpiece 100, and then the workpiece 100 can be honed by rotating the honing head 2. After the honing is completed The positioning mechanism 4 releases the lock on the workpiece 100, and the bracket carrier 33 drives the bracket 31 to bring the workpiece 100 to reset. The bracket cylinder 32 also drives the bracket 31 to bring the workpiece 100 down. When the bracket 31 falls to a position below the unloading inclined wedge plate 34, the workpiece 100 has crossed the baffle 341 in the horizontal upstream and downstream directions at this time. Therefore, the workpiece 100 can rely on its own weight to roll unhindered on the unloading inclined wedge plate 34 to the downstream material receiving mechanism 5 area until it falls into the material receiving box 51 and is stored.

[0025] During the above-mentioned use, the tubular and easy-to-roll characteristics of the workpiece 100 are fully utilized to effectively limit its position, so that the workpiece 100, with the cooperation of the bracket 31 and the unloading wedge plate 34, realizes a fast process of blocking-processing-releasing, effectively improving the processing efficiency. The cost of the horizontal honing machine is significantly lower than that of the structure of the gantry truss and the robotic arm combination.

[0026] Further, in the present embodiment, the positioning mechanism 4 includes a rotating chuck 41 and a self-centering jaw 42. The rotating chuck 41 is arranged on the side of the feeding mechanism 3 facing the honing head 2. The rotating chuck 41 is used to squeeze and clamp the workpiece 100 toward one end of the honing head 2. Specifically, the rotating chuck 41 includes an annular portion 412 and a plurality of movable arms 411 installed on the annular portion 412. The plurality of movable arms 411 are used to move along the radial direction of the annular portion 412 and clamp the workpiece 100 inserted in the annular portion 412. The self-centering jaw 42 is arranged on the side of the feeding mechanism 3 away from the honing head 2. The self-centering jaw 42 is used to rotate and clamp and position the workpiece 100 away from the end of the honing head 2. The self-centering jaw 42 includes a first rotating arm 421 and a second rotating arm 422. The ends of the first rotating arm 421 and the second rotating arm 422 are used to clamp the workpiece 100 together. At the same time, the ends of the first rotating arm 421 and the second rotating arm 422 have rotatable rollers 423. Through the above-mentioned structural setting, the rotating chuck 41 can lock the processing end of the workpiece 100 in a clamping manner, the self-centering jaws 42 can lock the distal end of the workpiece 100 in a clamping manner, and the rotating chuck 41 has a movable arm 411 for radially squeezing the outer wall of the workpiece 100 in multiple directions, and its fixing accuracy is higher, while the rotating arm of the self-centering jaws 42 is flexible to swing, and the end has a roller 423 for reducing friction, which mainly serves the purpose of limiting the radial movement of the workpiece, and can effectively improve the honing accuracy of the workpiece 100 and avoid vibration displacement of the workpiece during the honing process. Specifically, before the rotating chuck 41 positions the workpiece 100 during the above-mentioned use process, the position of the rotating card 41 is positioned by the rotating chuck carrier 413 at the bottom of the rotating chuck 41. Similarly, the self-centering jaw 42 is also positioned by the self-centering jaw carrier 424 to avoid other structures, so that it can be suitable for workpieces 100 of different sizes.

[0027] Specifically, in this embodiment, the rotating chuck 41 first clamps the workpiece 100, and the rotating chuck 41 plays a major fixing role, and then the self-centering jaw 42 clamps the other end of the workpiece 100, and the self-centering jaw 42 plays an auxiliary limit correction role.

[0028] Furthermore, the brackets 31 are arranged in a plurality of intervals parallel to the first direction, with the purpose of evenly applying force to the workpiece 100 in multiple sections along its own axial direction, thereby preventing the workpiece 100 from bending and deforming. In fact, the unloading inclined wedge plates 34 in this embodiment are also arranged in a plurality of intervals along the axial direction (parallel to the first direction) of the workpiece 100, achieving the same purpose and making the workpiece 100 roll more balanced and stable.

[0029] Furthermore, the material receiving mechanism 5 also includes a material receiving inclined wedge 52, a material receiving lifting cylinder 53, a discharge plate 54, and a roller 55. The material receiving inclined wedge 52 is arranged at the downstream end of the material receiving box 51, and the material receiving inclined wedge 52 has an inclined surface inclined toward the downstream end. The output end of the material receiving lifting cylinder 53 is connected to the material receiving inclined wedge 52, and the material receiving lifting cylinder 53 is used to lift the material receiving inclined wedge 52. The discharge plate 54 is installed at the downstream end of the material receiving inclined wedge 52, and the discharge plate 54 has an inclined surface inclined toward the downstream end. The roller 55 is arranged at the downstream end of the discharge plate 54. Specifically, through the above structure, similar to the method of using the discharging mechanism 1, after the workpiece 100 rolls onto the top surface of the receiving wedge 52 at the downstream end of the receiving box 51, the receiving wedge 52 lifts the workpiece 100 under the action of the receiving lifting cylinder 53, so that the workpiece 100 passes over the threshold at the end of the receiving box 51, until the workpiece 100 crosses the threshold and rolls downstream under the action of the corresponding slope, and after passing the unloading plate 54, the roller 55 catches the workpiece 100, and the roller 55 is used to transport the workpiece 100 to the corresponding collection area along a direction parallel to the first direction.

[0030] For further information, see Figure 1 The top of the material collecting box 11 is provided with a limit plate 111 facing the direction of the multiple workpieces 100. The limit plate 111 limits the height of the material collecting box 11 so that only one workpiece 100 can pass through the limit plate 111 and roll to the downstream of the material collecting box 11. Specifically, the limit plate 111 can be set as an inclined trapezoidal body fixed to the top of the material collecting box 11, and the slope surface on one side of the trapezoid is used to guide the stacked workpieces 100 to roll and fall in the material collecting box 11. Of course, a mechanism similar to the limit plate 111 can also be set in the material receiving mechanism 5 to realize the orderly transportation of the workpieces 100.

[0031] Furthermore, the side of the downhill section of the bracket 31 facing the discharge mechanism 1 is provided with a vertical retaining wall 311, and the retaining wall 311 is used to limit the workpiece 100. Specifically, by setting the retaining wall 311, when the step bracket 31 is fully lifted by the bracket cylinder 32, and the previous workpiece 100 is not released after being honed, another workpiece 100 can be received from the discharge mechanism 1 in advance and dropped to the downstream, so that the retaining wall 311 and the guide plate 14 can jointly lift the other workpiece 100, and after the bracket 31 falls, the processed workpiece 100 rolls away from the downstream side of the baffle 341 of the unloading inclined wedge plate 34, and the other workpiece is re-caged by the upstream surface of the baffle 341 and enters the next processing cycle. Therefore, through the structure of this embodiment, orderly cyclic processing of the assembly line can be realized, the circulation speed of the workpiece 100 in the assembly line can be accelerated, and the processing efficiency can be improved.
