Detailed implementation manners

[0026] The core of the present invention provides a honing machine, which improves the machining accuracy of the workpiece while reducing the floor area of the equipment.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-4 , the embodiment of the present invention provides a honing machine, including a feeding mechanism 1, a sequential loading mechanism 14, at least two honing stations 2, a discharging mechanism 4, and a honing machining mechanism; among them, the feeding mechanism 1, the honing station 2, and the discharging mechanism 4 are arranged in sequence along the processing direction, the sequential loading mechanism 14 is located on the feeding path of the feeding mechanism 1, and the honing stations 2 are arranged in one-to-one correspondence with the honing machining mechanism, that is, each honing machining mechanism processes the workpiece 13 on one honing station 2; the honing machine includes a multi-process machining mode and a same-process machining mode. When the honing machine switches to the multi-process machining mode, the sequential loading mechanism 14 loads the workpieces 13 one by one, and the workpiece 13 undergoes a honing process every time it passes through one honing station 2, and the machining sizes of each honing station 2 are different; when the honing machine switches to the same-process machining mode, the sequential loading mechanism 14 loads multiple workpieces 13 at the same time, and the number of workpieces 13 loaded at the same time is the same as the number of honing stations 2, and the machining sizes of each honing station 2 are the same.

[0029] The honing machine itself has multiple honing stations 2 and honing processing mechanisms. Therefore, according to the processing accuracy requirements of the workpiece 13, it can switch between multi-process processing mode and same-process processing mode. In the multi-process processing mode, a workpiece 13 can be honed multiple times to obtain higher processing accuracy. In the same-process processing mode, multiple honing stations 2 perform a honing process simultaneously, thus improving the processing efficiency. It realizes that one device can meet two working requirements with quick switching. This honing machine can not only meet the requirements of processing accuracy but also reduce the floor area.

[0030] Further, in this embodiment, the number of honing stations 2 is two, which are the first honing station 21 and the second honing station 22 in sequence along the feeding direction; the number of honing processing mechanisms is two, the first honing processing mechanism corresponds to the first honing station 21, and the second honing processing mechanism corresponds to the second honing station 22. Of course, according to actual needs, the number of honing stations 2 and honing processing mechanisms can also be three or more.

[0031] Taking two honing stations 2 as an example for illustration, in this embodiment, the sequential loading mechanism 14 includes a first stop mechanism 143, a second stop mechanism 142, and a feeding mechanism 141. The first stop mechanism 143 and the second stop mechanism 142 are arranged in sequence along the feeding direction. The position corresponding to the first stop mechanism 143 is the first stop position, and the position corresponding to the second stop mechanism 142 is the second stop position. When there is no workpiece 13 at the second stop position, the first stop mechanism 143 releases. When there is a workpiece 13 at the second stop position 142, the first stop mechanism 143 blocks. The feeding mechanism 141 is used to push the workpiece 13 at the second stop position to the first honing station 21 in the multi-process processing mode. In the same-process processing mode, the feeding mechanism 141 is used to simultaneously push the workpieces at the first stop position and the second stop position to the first honing station 21 and the second honing station 22 respectively.

[0032] The specific working process of the first stop mechanism 143 and the second stop mechanism 142 is as follows: When the workpiece 13 enters the feeding mechanism 1 and moves towards the machine tool, when it reaches the first stop position, if there is no workpiece 13 at the second stop position, the first stop mechanism 143 does not block and releases one workpiece 13 to pass through. If there is a workpiece 13 at the second stop position, there is no need to let the workpiece 13 pass. Therefore, the first stop mechanism 143 blocks and does not release. When there are workpieces 13 at both the first stop position and the second stop position, the feeding mechanism 1 stops feeding.

[0033] The specific working process of the feeding mechanism 141 is as follows: When the honing machine switches to the multi-process machining mode, that is, a workpiece 13 needs to be honed twice, the workpiece 13 enters the feeding mechanism 1 and moves towards the machine tool. When there are workpieces 13 parked at both the first material blocking position and the second material blocking position, the feeding mechanism 1 stops moving. At this time, both the first material blocking mechanism 143 and the second material blocking mechanism 142 retract and no longer block the feeding mechanism 1. Then, the feeding mechanism 141 moves between the first material blocking mechanism 143 and the second material blocking mechanism 142, and pushes the workpiece 13 at the second material blocking position to the first honing station 21 for the subsequent first honing process. At the same time, the workpiece 13 that has completed the first honing process and was originally at the first honing station 21 is pushed to the second honing station 22, and the workpiece 13 that has completed the second honing process and was originally at the second honing station 22 is simultaneously pushed onto the discharging mechanism 4. After that, the feeding mechanism 141 returns to its original position and waits. The discharging mechanism 4 moves to move the workpiece 13 that has completed the second honing process to the end of the discharging mechanism 4. After the workpieces currently at the first honing station 21 and the second honing station 22 complete their respective honing processes, the feeding mechanism 141 moves between the first material blocking position and the second material blocking position again for the next feeding, and only one workpiece 13 is pushed to the next honing station 2 each time, and so on in a cycle.

[0034] When the honing machine switches to the same-process machining mode, that is, the same honing process is performed at each honing station 2, and only the first honing process is performed, the workpiece 13 enters the feeding mechanism 1 and moves towards the machine tool. When there are workpieces 13 parked at both the first material blocking position and the second material blocking position, the feeding mechanism 1 stops moving. At this time, both the first material blocking mechanism 143 and the second material blocking mechanism 142 retract and no longer block the feeding mechanism 1. Then, the feeding mechanism 141 moves to the upstream position of the first material blocking mechanism 143, and moves the workpiece 13 at the second material blocking position, the workpiece 13 at the first material blocking position, the workpiece 13 that has completed the first honing process at the first honing station 21, and the workpiece 13 (if any) that has completed the first honing process at the second honing station 22 as a whole towards the discharging mechanism 4, and transports the two workpieces 14 that have completed the first honing to the discharging mechanism 4 at one time, while transporting the two unprocessed workpieces to the second honing station 22 and the first honing station 21 respectively at one time. After that, the feeding mechanism 141 returns to its original position and waits. The discharging mechanism 4 moves to move the workpiece 13 that has completed one honing process to the end of the discharging mechanism 4. After the workpieces 13 currently at the first honing station 21 and the second honing station 22 complete one honing process, the feeding mechanism 141 moves to the upstream position of the first material blocking position again for the next feeding, and two workpieces 13 are pushed to the first honing station 21 and the second honing station 22 respectively each time, and so on in a cycle.

[0035] Further, in this embodiment, both the first material blocking mechanism 143 and the second material blocking mechanism 142 are cylinders or hydraulic cylinders. When blocking, the cylinder or hydraulic cylinder extends, and when releasing, the cylinder or hydraulic cylinder retracts. The feeding mechanism 141 is controlled by a servo motor and is driven by a lead screw.

[0036] As Figure 4 shown, in order to firmly position the workpiece 13 on the honing station 2, in this embodiment, the honing station 2 is provided with a machine tool fixture 15 for fixing the workpiece 13. The machine tool fixture 15 is a two-station fixture, and a replaceable bottom plate is provided on the machine tool fixture 15.

[0037] This embodiment provides a specific honing processing mechanism. Each honing processing mechanism includes a main shaft, a rubber airbag fixture 3, a honing head, a rotational driving component, and a linear driving component; the first honing processing mechanism and the second honing processing mechanism share a numerical control system. Among them, the honing head is fixed to the lower end of the main shaft, the linear driving component drives the main shaft to move up and down, and the rotational driving component drives the main shaft to rotate; the rubber airbag fixture 3 is used to move up and down and clamp the workpiece 13; the numerical control system is used to control the actions of the rotational driving component, the linear driving component, and the rubber airbag fixture 3.

[0038] Specifically, taking two honing processing mechanisms as an example for illustration, the first honing processing mechanism includes a first main shaft 7, a first rotational driving component 12, a first linear driving component 10, a first honing head, and a first rubber airbag fixture; the second honing processing mechanism includes a second main shaft 8, a second rotational driving component 11, a second linear driving component 9, a second honing head, and a second rubber airbag fixture. Among them, both the rotational driving component and the linear driving component are servo motors.

[0039] During operation, the first rubber airbag fixture and the second rubber airbag fixture descend to wrap and clamp the workpiece 13. The first linear driving component 10 drives the first main shaft 7 to descend, and the second linear driving component 9 drives the second main shaft 8 to descend. When the first honing head and the second honing head are about to contact their respective workpieces 13, the first rotational driving component 12 drives the first main shaft 7 to rotate, and the second rotational driving component 11 drives the second main shaft 8 to rotate. The workpiece 13 is reciprocally honed according to the honing program set by the numerical control system. By respectively controlling the linear reciprocating movement and rotation of the main shaft through the linear driving component and the rotational driving component, the mesh angle of any cylinder hole can be achieved. After honing is completed, the first main shaft 7 and the second main shaft 8 rise and stop rotating. The first rubber airbag fixture and the second rubber airbag fixture release their respective workpieces 13 and rise to a position higher than the workpiece 13, completing one honing process.

[0040] As Figure 1 and Figure 2As shown in the figure, in this embodiment, the honing machine further includes a cooling system 5 for spraying coolant onto the honing station 2. Specifically, the cooling system 5 includes a spray pipe, a water tank, a filtering component, and a water pump. The spray pipe, the water pump, and the water tank are connected, and the filtering component is arranged at the water return port of the water tank. When the workpiece 13 is being honed, the cooling system 5 operates, and the coolant flushes the inner wall of the workpiece 13, cools the workpiece 13, and flushes the honing sludge into the water tank, where it is filtered by the filtering component, and the coolant is recycled. Among them, the filtering component is a centrifugal filter, the coolant temperature is kept constant at 20 - 25 °C, and the cooling system 5 is equipped with two sets of water pumps, which are respectively used for cooling two workpieces 13.

[0041] Furthermore, in this embodiment, the honing machine further includes an oil mist collector 6 for discharging and collecting the oil and gas inside the honing machine.

[0042] In this embodiment, the honing machine further includes a measuring system for measuring the machining dimensions of the workpiece 13. The measuring system is composed of a measuring instrument, a rotary sealing mechanism, compressed air filtration, and a voltage stabilizing element. During the honing process, the measuring system dynamically tracks the dimensional changes of the hole of the workpiece being processed. After reaching the set machining dimensions, the honing process is automatically terminated, and the data can be output.

[0043] Furthermore, in this embodiment, the honing machine further includes a protective cover 16, and the honing station 2, the honing machining mechanism, the cooling system 5, and the measuring system are all located inside the protective cover 16.

[0044] In this embodiment, the feeding mechanism 1 is a powered roller track with a track height of 1000 ± 50 mm, and the total length of the machine tool fixture 15 and the feeding mechanism 1 is 3800 mm. The powered roller track consists of powered rollers. The discharging mechanism 4 is a straight-through powered roller track, which is equipped with a full material detection switch, and the machine tool will alarm when the material is full.

[0045] The honing machine is equipped with information-based and intelligent interfaces, and can collect its equipment status, alarm information, machining parameters, and data.

[0046] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. For the same or similar parts among the embodiments, reference can be made to each other.
