Durable honing machine

Abstract

The utility model relates to a durable honing machine. The honing machine comprises a base; the honing assembly comprises a first motor slidably arranged on the base, the output end of the first motor is connected with the rear end of a first rotating shaft, and the front end of the first rotating shaft is connected with a grinding head; the supporting assembly comprises a support which is erected on the base and is perpendicular to the length direction of the base. Due to the fact that the first thread and the second thread are symmetrically arranged on the outer side of the lead screw, namely, the spiral directions of the first thread and the second thread are opposite, by rotating the lead screw, two clamping blocks and the lead screw generate thread displacement correspondingly, the two clamping blocks are close to or away from each other oppositely at the same time, and the outer surfaces of four rolling wheels are just tangent to the outer surface of a first rotating shaft; in addition, due to the fact that the rolling wheel can rotate along with the first rotating shaft, resistance to the first rotating shaft and abrasion to the first rotating shaft are small, and the service life of the honing machine is prolonged.

Description

Technical Field

[0001] This utility model relates to the field of honing machine technology, and in particular to a durable honing machine. Background Technology

[0002] A horizontal honing machine is used to grind the inner holes of cylindrical workpieces. It typically includes a machine tool, a rotating shaft mounted above the machine tool and capable of reciprocating along the machine tool, and a honing head mounted on the spindle. During processing, the spindle rotates, driving the honing head. Simultaneously, the rotating honing head reciprocates along the axial direction of the workpiece's inner hole, thus machining the inner hole.

[0003] However, horizontal honing machines typically use U-shaped supports to support the rotating shaft. Over time, the rotating shaft wears down due to the friction between the shaft and the U-shaped support, which reduces the shaft's service life.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model discloses a durable honing machine to solve the problem of shaft wear caused by long-term use and rotational friction with the support components, which reduces the service life of the shaft.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A durable honing machine includes: a base; a honing assembly including a first motor slidably mounted on the base, the output end of the first motor being connected to the rear end of a first rotating shaft, and the front end of the first rotating shaft being connected to a grinding head; and a support assembly including: a bracket mounted on the base and perpendicular to the length direction of the base; two clamping blocks slidably mounted on the bracket and symmetrically arranged relative to the longitudinal axis of the bracket, with two rollers rotatably mounted on opposite sides of the two clamping blocks, the rollers protruding from adjacent side surfaces of the clamping blocks; and a screw rotatably mounted inside the bracket and perpendicular to the length direction of the base, with a first thread and a second thread symmetrically arranged on the outer side of the screw, one of the clamping blocks threadedly connected to the outer side of the first thread, and the other clamping block threadedly connected to the outer side of the second thread; wherein the first rotating shaft passes between the two clamping blocks, and the outer surface of the first rotating shaft is tangent to the outer surfaces of the four rollers.

[0008] A further technical solution is that the rollers on the two clamping blocks are symmetrically arranged with respect to the longitudinal axis of the bracket, and the rollers on the same clamping block are vertically spaced apart; the support assembly also includes a third motor, which is disposed on the side of the bracket and its output end is connected to the side of the screw.

[0009] A further technical solution is that the bracket includes: two vertical plates, which are disposed at the front ends of both sides of the base; two horizontal plates, which are connected to the upper ends between the two vertical plates and are spaced apart along the length of the base; and a locking block, which is disposed on the adjacent side of the two horizontal plates; the locking block has a locking groove at the lower ends of its front and rear sides, and the locking block is respectively locked into the locking groove.

[0010] A further technical solution is that the clamping block includes: a through hole, which is formed through the clamping block along the length direction of the base; and a second rotating shaft, which passes through the through hole and the roller.

[0011] A further technical solution is that the through holes have eight holes, which are symmetrically arranged relative to the longitudinal axis of the bracket.

[0012] A further technical solution is that the base includes: a slide rail, which is arranged on both sides of the upper end of the base along the length direction of the base; a base plate is provided at the lower end of the first motor, and sliders are provided on both sides of the lower end of the base plate, the sliders are engaged with the slide rail and slide along the slide rail.

[0013] A further technical solution is that the base includes: a lead screw, rotatably disposed within the base; a second motor, disposed at the rear end of the inner side of the base, with its output end connected to the rear end of the lead screw; and a connecting block, disposed at the lower end of the base plate, threadedly connected to the lead screw.

[0014] A further technical solution is that a groove is formed on one side adjacent to the clamping block, and the position of the groove corresponds to the side of the first rotating shaft.

[0015] The beneficial effects of this utility model embodiment are as follows:

[0016] (I) This utility model discloses a durable honing machine, including a base, a honing assembly, and a support assembly. Since the first and second threads are symmetrically arranged on the outside of the lead screw, i.e., the first and second threads have opposite helical directions, rotating the lead screw causes the two clamping blocks to undergo threaded displacement with the lead screw. The two clamping blocks simultaneously move closer or further apart, so that the outer surfaces of the four rollers are tangent to the outer surface of the first rotating shaft, thus clamping the first rotating shaft. Furthermore, since the rollers can rotate with the first rotating shaft, the resistance and wear on the first rotating shaft are reduced, improving the service life of the honing machine.

[0017] (ii) Furthermore, the rollers on the two clamping blocks are symmetrically arranged with respect to the longitudinal axis of the support, and the rollers on the same clamping block are vertically spaced apart. The rollers can provide circumferential support for the first rotating shaft, resulting in high operational stability of the honing machine.

[0018] (iii) Furthermore, there are 8 through holes, which are symmetrically arranged relative to the longitudinal axis of the bracket, and the positions of the roller and the second shaft can be adjusted according to the size of the first shaft. Attached Figure Description

[0028] like Figure 1 As shown, the honing machine includes a base 1, a honing assembly 3, and a support assembly 2.

[0029] The base 1 is a semi-frame structure with the opening facing upwards.

[0030] like Figure 1 As shown, the honing assembly 3 includes a first motor 31 slidably mounted on a base 1. The output end of the first motor 31 is connected to the rear end of a first rotating shaft 32, and the front end of the first rotating shaft 32 is connected to a grinding head 33. Exemplarily, the base 1 includes a slide rail 11, which is disposed on both sides of the upper end of the base 1 along its length. A base plate 34 is disposed at the lower end of the first motor 31, and sliders 341 are disposed on both sides of the lower end of the base plate 34. The sliders 341 are engaged with the slide rail 11 and slide along the slide rail 11.

[0031] like Figure 2 and Figure 3 As shown, the support assembly 2 includes a bracket 21, a clamping block 24, and a screw 23.

[0032] The bracket 21 is mounted on the base 1, perpendicular to the length of the base 1. Two clamping blocks 24 are slidably mounted on the bracket 21, symmetrically arranged with respect to the longitudinal axis of the bracket 21. Two rollers 25 are rotatably mounted on opposite sides of each clamping block 24, with the rollers 25 protruding from the surfaces of adjacent sides of the clamping blocks 24. Exemplarily, the bracket 21 includes vertical plates 211, horizontal plates 212, and locking blocks 213. Two vertical plates 211 are located at the front ends of both sides of the base 1. Two horizontal plates 212 are connected to the upper ends between the two vertical plates 211, spaced apart along the length of the base 1. Locking blocks 213 are located on adjacent sides of the two horizontal plates 212. Slots 241 are formed at the lower ends of the front and rear sides of the clamping blocks 24, and the locking blocks 213 are respectively engaged in the slots 241, which slide relative to the locking blocks 213 along the length of the horizontal plate. Exemplarily, the clamping block 24 includes a through hole 243 and a second rotating shaft 251. A through hole 243 is formed along the length of the base 1 on the clamping block 24. The second rotating shaft 251 passes through the through hole 243 and the roller 25. Preferably, there are eight through holes 243, which are symmetrically arranged with respect to the longitudinal axis of the bracket 21, so that the positions of the roller 25 and the second rotating shaft 251 can be adjusted according to the size of the first rotating shaft 32.

[0033] The screw 23 is rotatably mounted inside the bracket 21, perpendicular to the length direction of the base 1. A first thread 231 and a second thread 232 are symmetrically arranged on the outer side of the screw 23. One clamping block 24 is threaded to the outer side of the first thread 231, and the other clamping block 24 is threaded to the outer side of the second thread 232. A first rotating shaft 32 passes between the two clamping blocks 24, and the outer surface of the first rotating shaft 32 is tangent to the outer surfaces of the four rollers 25. Preferably, the rollers 25 on the two clamping blocks 24 are symmetrically arranged with respect to the longitudinal axis of the bracket 21, and the rollers 25 on the same clamping block 24 are vertically spaced. The support assembly 2 also includes a third motor 22, which is located on the side of the bracket 21, and its output end is connected to the side of the screw 23.

[0034] like Figure 1 and Figure 2 As shown, the base 1 further includes a lead screw 12, a second motor 13, and a connecting block 342. The lead screw 12 is rotatably disposed within the base 1. The second motor 13 is disposed at the rear end of the inner side of the base 1, and its output end is connected to the rear end of the lead screw 12. The connecting block 342 is disposed at the lower end of the base plate 34 and is threadedly connected to the lead screw 12. Exemplarily, the lead screw is parallel to the length direction of the base 1. A bearing seat 14 is disposed at the front end of the inner side of the base 1, and the front end of the lead screw 12 passes through the bearing seat 14.

[0035] like Figure 3 As shown, further, a groove 242 is provided on one side adjacent to the clamping block 24, and the position of the groove 242 corresponds to the side of the first rotating shaft 32 to avoid interference with the first rotating shaft 32.

[0036] In this embodiment, since the first thread 231 and the second thread 232 are symmetrically arranged on the outside of the lead screw 12, that is, the first thread 231 and the second thread 232 have opposite helical directions, by rotating the lead screw 12, the two clamping blocks 24 respectively undergo thread displacement with the lead screw 12, and the two clamping blocks 24 simultaneously move closer or further away from each other, so that the outer surfaces of the four rollers 25 are just tangent to the outer surface of the first rotating shaft 32, thereby clamping the first rotating shaft 32. Since the rollers 25 can rotate with the first rotating shaft 32, the resistance and wear on the first rotating shaft 32 are small, which improves the service life of the honing machine. In addition, the rollers 25 can provide circumferential support for the first rotating shaft 32, and the honing machine has high operational stability.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
