Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of machining, and specifically relates to a high-precision roller connecting device of a grinding machine. BACKGROUND

[0002] A mold core is widely used in the field of machining and manufacturing. In the machining process, the mold core is ground by a grinding machine, and this process usually relies on manual operation. However, this method not only significantly increases the labor intensity of workers, but also is difficult to meet the high-precision requirements of mold core machining. For example, the roundness of the mold core needs to be accurate to 0.005 millimeters, the straightness of the mold core with a length of 1.6 meters to 2.6 meters must be controlled within 0.02 millimeters, and the machining needs to be completed at one time. These stringent requirements not only increase the production cost, but also reduce the machining efficiency and product quality, so that the traditional manual operation is difficult to adapt to the high-standard requirements of modern machining.

[0003] In particular, in the batch machining process, the length characteristics of the mold core further highlight the limitations of manual operation. The machining of long workpieces often makes it difficult for workers to accurately control the machining results of each mold, thereby affecting the overall qualification rate of the mold. In this case, only manual operation will not only increase the labor intensity of workers, but also may cause rework due to quality problems, thereby causing production process delay and affecting overall production efficiency.

[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0028] like Figures 1-3 As shown, a high-precision roller receiving device for grinding machines in one embodiment of this utility model includes a base 1 and a roller receiving assembly 7. The roller receiving assembly 7 is installed on the upper end of the base 1. In use, the roller receiving assembly 7 is aligned with the discharge port of the grinding machine and parallel to the discharge direction, enabling the receiving of the mold mandrel. The base 1 allows for changes in the position and height of the roller receiving assembly 7, enabling it to adapt to grinding machines and mold mandrels of different specifications.

[0029] Specifically, such as Figures 1-5 As shown, the roller assembly 7 includes a load-bearing crossbeam 8, on which multiple sets of connecting plates 9 are welded. Each set of connecting plates 9 consists of two plates, and an X-shaped hinge mechanism is installed between the two connecting plates 9. A deep groove ball bearing 11 is fixedly connected to the X-shaped hinge mechanism, and a tensioning mechanism is installed at the lower end of the X-shaped hinge mechanism. The tensioning mechanism reduces the included angle formed by the X-shaped hinge mechanism. When the mold mandrel is placed on the deep groove ball bearing 11, the X-shaped hinge mechanism undergoes corresponding deformation, causing the outer wall of the deep groove ball bearing 11 to fit against the outer wall of the mold mandrel, thereby facilitating the removal of the mold mandrel from the grinding machine.

[0030] Specifically, such as Figures 1-5As shown, the X-shaped hinged mechanism includes two connecting rods 10, which are crossed in X shape. The middle part of the connecting rod 10 is provided with a fourth through hole 1001, and the middle part of the connecting plate 9 is provided with a third through hole 901. A first bolt 13 is installed on the connecting plate 9 and matches the third through hole 901. One end of the first bolt 13 passes through the third through hole 901 and the two connecting rods 10, and then passes out from the other third through hole 901 and is threadedly connected with a second nut 14. That is, the two connecting rods 10 are rotationally connected between the two connecting plates 9.

[0031] Further, a strip-shaped hole 802 is formed in the load-bearing cross beam 8, the lower end of the connecting rod 10 passes through the strip-shaped hole 802, the lower end of the connecting rod 10 is provided with a sixth through hole 1003, and the tensioning mechanism includes a hook spring 20. An eighth through hole 801 is formed in the load-bearing cross beam 8 and matches the sixth through hole 1003. The two ends of the hook spring 20 are fixed with the sixth through hole 1003 and the eighth through hole 801, respectively. The number of hook springs 20 is two, and the two hook springs 20 correspond to the two connecting rods 10. The included angle between the two connecting rods 10 is reduced by the hook spring 20.

[0032] In addition, the hook spring 20 can also be fixed with the two sixth through holes 1003, respectively, to reduce the included angle between the two connecting rods 10.

[0033] As shown in Figures 1-5 , the upper end of the connecting rod 10 is provided with a fifth through hole 1002, and the deep groove ball bearing 11 is fixedly connected with a second screw rod 1101 matching the fifth through hole 1002. The second screw rod 1101 passes through the fifth through hole 1002 and is threadedly connected with a first nut 12. That is, the deep groove ball bearing 11 is fixed by the bolt, and the deep groove ball bearing 11 is detachable. When the included angle between the two connecting rods 10 is reduced, the two deep groove ball bearings 11 will be attached.

[0034] As shown in Figures 1-5 , the lower end of the base 1 is also provided with an adjusting assembly 15. The adjusting assembly 15 is used to limit the maximum opening angle of the X-shaped hinged mechanism, so that the X-shaped hinged mechanism can adapt to the mold mandrel with small outer diameter.

[0035] As shown in Figures 4-5 , the adjusting assembly 15 includes a cuboid 16 fixedly connected to the lower end of the load-bearing cross beam 8. The end of the cuboid 16 close to the X-shaped hinged mechanism is provided with a groove 1601. A pair of sliding blocks 17 are slidingly connected in the groove 1601. The sliding blocks 17 are fixedly connected with a contact plate 18 matching the X-shaped hinged mechanism, and the contact plate 18 is located on the outer side of the X-shaped hinged mechanism.

[0036] Specifically, as shown in Figure 5As shown, the load-bearing crossbeam 8 is provided with a second through hole 803, the cuboid 16 is provided with a seventh through hole 1602 matched with the second through hole 803, and the sliding block 17 is provided with a threaded hole 1701 matched with the seventh through hole 1602. The load-bearing crossbeam 8 is provided with a bidirectional screw rod 19 matched with the second through hole 803, the bidirectional screw rod 19 passes through the second through hole 803, the seventh through hole 1602 and the threaded hole 1701 and is in threaded connection with the threaded hole 1701. The bidirectional screw rod 19 is fixedly connected with a bearing 1901 matched with the second through hole 803. That is, the bidirectional screw rod 19 is rotatably connected to the load-bearing crossbeam 8. In the rotating process, the second through hole 803 can move with the sliding block 17 to the opposite direction or the opposite direction, so as to limit the maximum included angle of the X-shaped hinged mechanism. When the mold core shaft with a small specification is as far as possible avoided, the mold core shaft will not fall after being in contact with the deep groove ball bearing 11.

[0037] As shown in the drawings, Figure 6 The base 1 comprises a bottom plate 2, the bottom plate 2 is fixedly connected with a stand 3, the stand 3 is fixedly connected with a crossbeam 4 away from the bottom plate 2, the crossbeam 4 is provided with a first through hole 401, and the crossbeam 4 is provided with a first screw rod 5 matched with the first through hole 401. Two locking nuts 6 are in threaded connection with the first screw rod 5. When the locking nuts 6 are installed, one locking nut 6 is first in threaded connection with the first screw rod 5, then the first screw rod 5 passes through the first through hole 401, and then the locking nut 6 is in threaded connection with the end passing through the first through hole 401, so that the crossbeam 4 is located between the two locking nuts 6, the locking nuts 6 are tightened, and the fixation of the first screw rod 5 is realized. By rotating the locking nuts 6 to change the positions of the locking nuts 6 on the first screw rod 5, the length of the first screw rod 5 at the upper end of the crossbeam 4 can be changed, so that the height of the roller assembly 7 is changed, and the roller assembly 7 can adapt to different specifications of the grinding machine.

[0038] As shown in the drawings, Figures 1-6 The lower end of the load-bearing crossbeam 8 is fixedly connected with a sleeve 804, the upper end of the first screw rod 5 can be inserted into the sleeve 804, and the load-bearing crossbeam 8 is in threaded connection with a second screw 21, the second screw 21 passes through the load-bearing crossbeam 8 and is in threaded connection with the locking nut 6, so as to realize the detachable installation of the roller assembly 7 and the base 1.

[0039] When assembled, the base 1 and the roller assembly 7 are generally assembled respectively, and then the base 1 and the roller assembly 7 are assembled. When the base 1 is assembled, the locking nuts 6 are only in threaded connection with the first screw rod 5, and then the first screw rod 5 passes through the first through hole 401 and is in threaded connection with the other locking nut 6. When the first screw rod 5 is assembled, the upper end surface of the first screw rod 5 is as far as possible ensured to be on the same horizontal plane.

[0040] When the roller assembly 7 is assembled, first, the two connecting rods 10 are placed between the two connecting plates 9, and the preliminary assembly of the connecting plate 9 and the connecting rod 10 is completed by passing the first bolt 13 through the third through hole 901 and the fourth through hole 1001, and the second nut 14 is screwed on the first bolt 13. First, install the deep groove ball bearing 11 on the upper end of the connecting rod 10, then install the hook spring 20 between the sixth through hole 1003 and the eighth through hole 801, so that the hook spring 20 can reduce the included angle formed by the two connecting rods 10. And by rotating the bidirectional screw rod 19, the contact plate 18 is located at the outer end of the two connecting rods 10, and the above steps are repeated until the connecting plate 9 is installed with the connecting rod 10.

[0041] When assembling the base 1 and the roller assembly 7, the sleeve 804 is aligned with the first screw rod 5, the sleeve 804 can be simply fixed, and then the load-bearing beam 8 and the locking nut 6 are screwed together by the second bolt 21. After the base 1 and the roller assembly 7 are assembled, the roller assembly 7 needs to be leveled, generally using a level, measuring the inclination angle of the load-bearing beam 8 by the level, and adjusting the locking nut 6 according to the inclination position, so that the position of the first screw rod 5 is lowered or raised, so that the upper surface of the load-bearing beam 8 is horizontal to the horizontal plane.

[0042] When the base 1 and the roller assembly 7 are assembled, and the position of the roller assembly 7 is also adjusted, the roller assembly 7 is aligned with the discharge port of the grinding machine, so that the roller assembly 7 is in the material receiving position, and the bidirectional screw rod 19 is rotated, so that the bidirectional screw rod 19 changes the maximum opening angle of the two connecting rods 10, to avoid the situation that the mold core shaft falls between the two connecting rods 10 and does not contact the deep groove ball bearing 11 due to the opening angle of the connecting rod 10 being too large.

[0043] The specific operation method of the utility model is:

[0044] Step one, align the roller assembly with the discharge port of the grinding machine and parallel to the discharge direction.

[0045] Step two, rotate the bidirectional screw rod 19 to control the deep groove ball bearing 11 outer ring to approach the discharge port of the grinding machine, and use a tape measure to measure the height of the two first screw rods 5, so that the height of the two first screw rods 5 remains consistent, that is, the upper end surface of the load-bearing beam 8 is horizontal to the horizontal plane, and the locking nut 6 is tightened.

[0046] Step three, in the stopped state of the grinding machine, first, the pre-processed mold core shaft is horizontally extended from the grinding machine inlet through the grinding machine discharge port.

[0047] Step four, use the bidirectional screw rod 19 to fine-tune the position of the deep groove ball bearing 11 so that the bearing outer ring surface is in good contact with the mold core shaft, and the mold core shaft is held horizontally and advances.

[0048] Step five, open the grinding wheel to prepare for grinding the mold, at this time there are 1 worker in front of and behind the grinding machine, the worker in front is responsible for sending the mold core shaft to be processed horizontally from the entrance of the grinding machine, at this time the mold is automatically advanced horizontally from the entrance to the exit under the action of the grinding wheel and the guide wheel of the grinding machine; the worker behind the exit of the grinding machine prepares to receive the mold core shaft after grinding by means of the high-precision roller receiving device of the grinding machine.

[0049] Step six, the two workers in front and behind send the mold into the entrance in turn, and the worker at the exit receives the mold to process reciprocatingly until each mold core shaft in the batch reaches the requirements of the drawing.

[0050] Step seven, stop the machine and remove the roller receiving device.
