For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0033] refer to Figure 1 A honing feed device according to a preferred embodiment of the present disclosure will be described in detail below, wherein the honing feed device includes a feed base 10, a feed thread seat 20, a feed thread rod 30 and a drive assembly 40.

[0034] See also Figure 2 The feed thread seat 20 is used to be connected to the honing device. The feed thread seat 20 is slidably arranged on the outer surface of the feed base 10 along the feed direction S, and a threaded hole 201 extending along the feed direction is formed in the feed thread seat 20.

[0035] Optionally, the feed base 10 includes a bottom plate 11 and a mounting plate 12. The mounting plate 12 is vertically arranged above the bottom plate 11. The feed thread seat 20 is slidably arranged on the bottom plate 11 along the feed direction S. The length direction of the bottom plate 11 is in the same direction as the feed direction S, and the bottom plate 11 is suitable for being stably mounted on the honing table in a manner parallel to the table surface of the honing table.

[0036] Optionally, one of the feed base 10 and the feed thread seat 20 is formed with a first guide portion 111 extending along the feed direction S, and the other is formed with a second guide portion 21 slidably matched with the first guide portion 111 .

[0037] In this way, when the feed thread seat 20 slides, under the cooperative guidance of the first guide portion 111 and the second guide portion 21 , the feed thread seat 20 can slide smoothly along the extension direction of the first guide portion 111 , that is, the feed direction S.

[0038] Specifically, the first guide portion 111 is configured as a guide rail or a guide groove, and the second guide portion 21 is configured as a guide block suitable for slidingly cooperating with the guide rail or the guide groove. For example, a guide rail is provided on the upper surface of the base plate 11, and the guide rail extends along the feed direction S, that is, away from the mounting plate 12 and toward the part to be honed. The guide block is provided on the lower surface of the feed thread seat 20, and the guide block is suitable for slidingly cooperating with the guide rail.

[0039] Optionally, the honing device includes a honing head, one end of which is connected to the feed thread seat 20, and the other end face is provided with a honing column, the honing column faces the hole of the part to be honed, and is used to be inserted into or pulled out of the hole of the part to be honed while fitting against the inner wall of the hole of the part to be honed, thereby honing the hole of the part to be honed, thereby increasing the aperture of the hole of the part to be honed.

[0040] The feed threaded rod 30 is threadedly arranged in the threaded hole 201. Optionally, the mounting plate 12 is formed with a circular mounting hole 1201. The feed threaded seat 20 is formed with a cylindrical mounting portion 22, and the mounting portion 22 is movably arranged in the mounting hole 1201, and the threaded hole 1201 passes through the end of the mounting portion 22. The feed threaded rod 30 passes through the mounting hole 1201 and is installed in the threaded hole 201.

[0041] The driving assembly 40 is connected to the feed thread rod 30, and is used to drive the feed thread rod 30 to move and rotate along the feed direction S. When the feed thread rod 30 moves, the feed thread seat 20 is driven by the feed thread rod 30 and moves synchronously with the feed thread rod 30, so that the feed thread seat 20 mainly feeds and slides along the feed direction S, and then the feed thread seat 20 can drive the honing device to perform main honing. When the feed thread rod 30 rotates, the feed thread seat 20 is driven by the feed thread rod 30 to move along the axial direction of the feed thread rod 30 (that is, the extension direction of its threaded hole 201, that is, the feed direction S), so that the feed thread seat 20 compensates for the feed sliding along the feed direction S, and then the feed thread seat 20 can drive the honing device to perform compensatory honing.

[0042] In other words, the driving assembly 40 can drive the feed threaded rod 30 to move along the feed direction S, and can also drive the feed threaded rod 30 to rotate. When it is necessary to hone the hole of the part to be honed, the driving assembly 40 first drives the feed threaded rod 30 to move along the feed direction S. The movement of the feed threaded rod 30 directly drives the feed threaded seat 20 to perform the main feed sliding along the feed direction S, so that the honing device can move from the initial position to the main honing position, and then the honing column on the honing device can be inserted into the hole of the part to be honed, and then the main honing of the hole of the part to be honed is performed. When the honing device is worn, for example, the honing column is worn or the size of the part to be honed is not standard, the main honing is not sufficient to hone the hole of the part to be honed. For example, the honing goal is to hone the hole diameter of the part to be honed from 8.95mm to 9mm. Due to the wear of the honing column or the non-standard size of the part to be honed, the hole diameter of the part after the main honing is only honed from 8.95mm to 8.995mm. At this time, the driving assembly 40 drives the feed thread rod 30 to rotate. Since the feed thread rod 30 is threadedly matched with the feed thread seat 20, and the feed thread seat 20 can slide along the feed direction S, the feed thread rod 30 rotates to drive the feed thread seat 20 to continue sliding along the feed direction S, so that the honing device can move from the main honing position to the compensation honing position, so that the honing column of the honing device can perform compensation honing on the holes of the part to be honed, and then further increase the aperture of the hole of the part to be honed, so as to achieve the purpose of honing the aperture from 8.995 mm to 9 mm for compensation honing.

[0043] In the above device, since the feed screw seat 20 of the present disclosure is slidably mounted on the outer surface of the feed base 10, the feed screw seat 20 is located outside the feed base 10, and when the feed screw seat 20, the feed base 10 and the feed screw rod 30 are assembled together, the external operation space is large, and the assembly operation is not easily restricted. Therefore, the device of the present disclosure is easy to assemble, convenient to assemble, and short in time.

[0044] According to some embodiments of the present disclosure, refer to Figure 1 and Figure 2 The driving assembly 40 includes a main driving member 41 and a compensating driving member 42. The main driving member 41 includes a driving cylinder 411. The driving cylinder 411 is connected to the feeding threaded rod 30.

[0045] Optionally, the main driving member 41 further includes a mounting base 412. The mounting base 412 and the feed thread seat 20 are arranged on opposite sides of the mounting plate 12. The driving cylinder 411 is arranged on the mounting base 412.

[0046] Optionally, the main driving member 41 further includes a driving member 413. The driving member 413 is connected between the driving cylinder 411 and the feeding threaded rod 30, and the feeding threaded rod 30 is rotatably connected to the driving member 413. In this way, when the driving cylinder 411 is running, the piston rod of the driving cylinder 411 drives the driving member 413 to move linearly along the feeding direction S, and the linear movement of the driving member 413 drives the feeding threaded rod 30 to move linearly along the feeding direction S.

[0047] Optionally, the driving member 413 further includes a pressing member 4131. One end surface of the pressing member 4131 is connected to the driving cylinder 411, and the feeding threaded rod 30 is rotatably connected to the other end surface of the pressing member 4131.

[0048] The driving assembly 40 further includes a pressure sensor 414 and a controller (not shown). The pressure sensor 414 is disposed on the mounting base 412. The pressing member 4131 cooperates with the pressure sensor 414 and is used to press the pressure sensor 414 after the main feed of the feed thread seat 20 slides into place. The controller is connected to the pressure sensor 414 and the driving cylinder 411 respectively, and is used to control the driving cylinder 411 to stop driving or reverse driving when the pressure sensor 414 is pressed.

[0049] In this way, when the pressure sensor 414 detects that the main feed slide of the feed thread seat 20 is in place, the controller controls the driving cylinder 411 to stop driving or reverse driving, so that during the driving process of the driving cylinder 411, the feed position of the feed thread seat 20 will never exceed the main feed position or the feed speed is zero when the main feed position is reached, thereby achieving the purpose of accurately controlling the feed size and ensuring the honing accuracy and honing stability of the honing machine. Such a setting can ensure the stability of the dimensional tolerance of the parts to be honed after the main honing, improve the honing accuracy, avoid the honing size being too large or too small, and reduce the probability of compensatory honing.

[0050] Optionally, the driving member 413 further includes a driving bearing 4132. The pressing member 4131 is connected to the driving cylinder 411. The driving bearing 4132 is arranged on an end surface of the pressing member 4131 away from the driving cylinder 411, and the feed threaded rod 30 is fixedly installed in the driving bearing 4132. In this way, when the feed threaded rod 30 rotates, the driving bearing 4132 can reduce the friction between the pressing member 4131 and the feed threaded rod 30, reduce wear, and reduce noise.

[0051] Optionally, the compensation drive member 42 includes a drive motor 421. The drive motor 421 is connected to the feed threaded rod 30 and is used to drive the feed threaded rod 30 to rotate. Specifically, the drive motor 421 is configured as a servo motor. The servo motor has a low operating frequency and simple logic for convenient control.

[0052] Optionally, the compensation driving member 42 further includes a driving gear 422 and a driven gear 423. The driving motor 421 is connected to the driving gear 422. The driven gear 423 is connected to the feeding threaded rod 30 and meshes with the driving gear 422.

[0053] In this way, when the driving motor 421 drives the driving gear 422 to rotate, the driving gear 422 drives the driven gear 423 to rotate, and the rotation of the driven gear 423 drives the feed threaded rod 30 to rotate, thereby enabling the feed threaded rod 30 to rotate.

[0054] According to some embodiments of the present disclosure, refer to Figure 2 and Figure 3 The honing feed device further comprises a feed connector 50. One end of the feed connector 50 is rotatably disposed on the feed thread seat 20, and the other end is used to connect the honing device.

[0055] In this way, when the honing column of the honing device is inserted into or pulled out of the hole of the part to be honed, the honing device and the feed connector 50 can rotate flexibly accordingly, thereby making the honing device and the feed connector 50 less prone to wear and damage.

[0056] Optionally, a connecting channel 202 is formed in the feed thread seat 20, the axial direction of the connecting channel 202 is in the same direction as the feed direction S, and the feed connector 50 is installed in the connecting channel 202 in a rotatable and axially positioned manner. It can be understood that the feeding connector 50 is installed in the connecting channel 202 in an axially positioned manner mainly means that after the feeding connector 50 is installed in the connecting channel 202, the axial movement of the feeding connector 50 along the connecting channel 202 is restricted, and the axial position of the feeding connector 50 in the connecting channel 202 hardly changes or changes within a preset range.

[0057] In this way, when the honing column of the honing device withdraws from the hole of the part to be honed and the feed thread seat 20 retreats, that is, moves in a direction away from the part to be honed, the feed connecting member 50 can be driven by the feed thread seat 20 and retreat synchronously with the feed thread seat 20, so that the feed connecting member 50 can drive the honing column of the honing device to withdraw from the hole of the part to be honed in a timely and smooth manner.

[0058] Specifically, the outer circumference of the feed thread seat 20 is formed with at least one positioning hole 203 communicating with the connecting channel 202. The outer circumference of the feed connector 50 is formed with a positioning groove 501 extending along the circumference thereof.

[0059] The honing feeding device further includes a positioning member 60. The positioning member 60 passes through the positioning hole 203 and is inserted into the positioning groove 501.

[0060] In this way, when the feed thread seat 20 retreats, the positioning member 60 is driven by the feed thread seat 20 and retreats synchronously, so that the feed connecting member 50 is pulled by the positioning member 60 and moves smoothly in a direction away from the part to be honed.

[0061] Optionally, there is a gap between one end of the positioning member 60 inserted into the positioning groove 501 and the bottom wall of the positioning groove 501. In this way, when the feeding connection member 50 rotates, no friction is generated between the positioning member 60 and the feeding connection member 50, resulting in less wear and less noise.

[0062] Optionally, the positioning groove 501 is annular, the positioning hole 203 is multiple, the multiple positioning holes 203 are arranged at intervals around the feed thread seat 20, and the multiple positioning members 60 are arranged one-to-one with the multiple positioning holes 203. Such an arrangement enables the positioning member 60 to uniformly apply tension to the feed connection member 50 along the circumference of the feed connection member 50, thereby ensuring that the feed connection member 50 can be smoothly pulled back in a relatively stable state.

[0063] In a specific example, there are six positioning members 60, and the positioning members 60 are configured as screws, and the inner wall of the positioning hole 203 is formed with an internal thread that matches the screw thread. The six screws pass through the six positioning holes 203 with internal threads and are installed in the positioning groove 501. However, it can be understood that the number of the positioning members 60 and the positioning holes 203 disclosed in the present invention includes but is not limited to this, and can be adaptively adjusted.

[0064] According to some embodiments of the present disclosure, refer to Figure 2 and Figure 4The honing feed device further includes a rotating bearing 70. The rotating bearing 70 is arranged on the feed thread seat 20, and the feed connector 50 is installed in the rotating bearing 70. In this way, when the feed connector 50 rotates, the rotating bearing 70 can reduce the friction between the feed thread seat 20 and the feed connector 50, reduce wear, and reduce noise. Specifically, the rotating bearing 70 can be a thrust ball bearing.

[0065] Optionally, see Figure 2 and Figure 3 The feed connection member 50 includes a rod 51 and a convex body 52. ​​The convex body 52 is arranged on the outer circumference of the rod 51. The rod 51 is rotatably and axially positioned in the connecting passage 202. An annular mounting groove 502 is formed between the outer circumference of the rod 51, the end surface of the feed thread seat 20 and the convex body 52. ​​The rotating bearing 70 is installed in the annular mounting groove 502. In this way, the rotating bearing 70 is firmly installed and is not easy to fall off.

[0066] Optionally, the rotating bearing 70 is fixedly connected to one or both of the feed thread seat 20 and the convex body 52. ​​In this way, the feed connector 50 is less likely to move relative to the feed thread seat 20 along the axial direction of the feed thread seat 20, thereby enabling the feed connector 50 to better maintain synchronous movement with the feed thread seat 20 when driven. It can be understood that the above specific configuration methods can be adaptively selected according to needs, but the above methods are all within the protection scope of the present disclosure.

[0067] Specifically, the rod portion 51 includes a first diameter section 511 and a second diameter section 512. The first diameter section 511 is installed in the connecting channel 202, and the first diameter section 511 is provided with the positioning groove 501. The second diameter section 512 is larger than the first diameter section 511, and the second diameter section 512 is formed with the convex body 52, and the end face of the feed thread seat 20 abuts against the end face of the second diameter section 512. In this way, the structure of this part is compact, and the abutment between the end face of the feed thread seat 20 and the end face of the second diameter section 512 can also prevent the feed connector 50 from being pulled back excessively.

[0068] The present disclosure also provides a honing machine, which has the honing feed device and the honing device as described above. The feed thread seat 20 of the honing feed device is connected to the honing device to drive the honing device to perform the main honing and the compensating honing.

[0069] Specifically, the honing device can be a vertical honing device or a horizontal honing device. In other words, the honing feeding device disclosed in the present invention can be used on a vertical honing device or a horizontal honing device, and a set of feeding systems can meet the feeding requirements of two types of equipment. The feeding system has good standardization and interchangeability, which reduces repeated design and manufacturing.

[0070] Other structures and operations of the honing machine according to the embodiment of the present disclosure are known to those skilled in the art and will not be described in detail here.

[0071] It should be understood by those skilled in the art that the embodiments of the present disclosure described above and shown in the accompanying drawings are only examples and do not limit the present disclosure. The advantages of the present disclosure have been fully and effectively realized. The functions and structural principles of the present disclosure have been demonstrated and explained in the embodiments, and the embodiments of the present disclosure may be deformed or modified in any way without departing from the principles.
