Detailed Implementation

[0022] To make the objectives, methods, and advantages of the embodiments of this utility model clearer, the method solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Example 1: As Figures 1-3 As shown, a turning and grinding integrated machining tool includes: a mounting plate 1, a turning device 2, and a grinding device 3. The mounting plate 1 is provided with a first slide rail 11; the turning device 2 is slidably connected to the first slide rail 11, and the turning device 2 is provided with a connecting plate 21 extending along the length direction of the first slide rail 11, and the connecting plate 21 is provided with a rack portion 211; the grinding device 3 is fixedly connected to the mounting plate 1, and the grinding device 3 includes: a grinding wheel 31, a rotating shaft 32, and a gear 33. The rotating shaft 32 is connected to the grinding wheel 31, and the rotating shaft 32 is provided with a telescopic portion 322; the gear 33 is connected to the telescopic portion 322, and the gear 33 can mesh with the rack portion 211.

[0024] In the implementation process, taking the machining of the bearing as an example, the specifications of each batch of bearings are different. After the bearing is placed in place, whether turning or grinding is needed to avoid the obstruction of another device. For example, when turning, the grinding device 3 needs to maintain a certain distance from the bearing, so the gap between the turning device 2 and the grinding device 3 is often greater than the workpiece 9 to be machined. When the workpiece 9 to be machined is turned, the turning device 2 and the grinding device 3 move synchronously, so that the turning device 2 is separated from the workpiece 9 to be machined, and the grinding wheel 31 on the grinding device 3 is in abutment with the workpiece 9 to be machined. At this time, the synchronous movement distance of the two devices is involved. If the distance between the grinding device 3 and the turning device 2 on the machine tool remains unchanged, when machining parts with reduced volume, the synchronous movement distance of the two devices is large. If the parts in the same batch are switched due to the large synchronous movement distance, the switching time is long, which further leads to a decrease in overall machining efficiency. Therefore, the distance between the grinding device 3 and the turning device 2 needs to be adjusted according to different specifications of the workpiece 9 to be machined. However, the additional driving device not only needs to occupy more installation space but also increases the economic cost.

[0025] The embodiment makes full use of the rotating motor on the grinding device 3, cooperates with the gear 33 and the rack part 211, and can adjust the distance between the grinding device 3 and the turning device 2. When the grinding function is needed, the telescopic part 322 is elongated, so that the gear 33 is separated from the rack part 211, and then the grinding device 3 is started. When the distance between the grinding device 3 and the turning device 2 needs to be adjusted, the telescopic part 322 is shortened, so that the gear 33 is engaged with the rack part 211, and then the rotating motor on the grinding device 3 is started. The rotating motor drives the rack through the gear 33, and the rack drives the turning device 2 to slide on the first slide rail 11. Since the grinding positions of different workpieces 9 to be machined are different, the height of the grinding wheel 31 also needs to be adjusted. The height of the grinding wheel 31 can be directly adjusted by the telescopic part 322, so that the telescopic part 322 has the characteristics of one thing with two functions. The telescopic part 322 can use the existing telescopic rod, that is, a section of the rotating shaft 32 is a telescopic rod. In order to ensure the stability of the movement of the turning device 2, two gears 33 can be provided to cooperate with two connecting plates 21 to realize movement. The turning device 2 and the grinding device 3 are both existing devices on the existing machining machine tool, and the structure of the embodiment will not be described again. The sliding connection is also prior art, which can be realized by the cooperation of the slide rail and the sliding block, and will not be described again.

[0026] Embodiment 2: In order to simply realize the synchronous movement of the grinding device 3 and the turning device 2, the embodiment is improved on the basis of Embodiment 1, as shown in Figures 1-3 The machining machine tool further comprises a mounting frame 4, and the mounting plate 1 is in sliding connection with a second slide rail 41 on the mounting frame 4.

[0027] In the implementation process, the mounting frame 4Figure 1 The vertical arrangement, since both the polishing device 3 and the turning device 2 are mounted on the mounting plate 1, when the two devices need to move synchronously, the mounting plate 1 can be moved on the second slide rail 41.

[0028] In order to realize the movement of the mounting plate 1 while avoiding the movement of the mounting plate 1 when the gear 33 drives the rack part 211 to move, on the basis of the embodiment 2, the embodiment 3 is improved as shown in the figure. Figure 4 In this embodiment, the mounting plate 1 is provided with a threaded hole and a guide hole along its length direction, the second slide rail 41 is provided with a threaded rod 5 matched with the threaded hole, the second slide rail 41 is provided with a guide rod 6 matched with the guide hole, the threaded rod 5 is connected with the first driving device 7, and the first driving device 7 can drive the threaded rod 5 to rotate.

[0029] In the specific implementation process, the first driving device 7 can adopt a rotary motor. When the gear 33 drives the turning device 2 to move through the rack part 211, the mounting plate 1 cannot move due to the cooperation of the threaded rod 5 and the threaded hole. When it is needed to move the mounting plate 1, the telescopic part 322 is extended to make the gear 33 disengage from the rack part 211, and then the first driving device 7 is started to drive the threaded rod 5 to rotate, thereby driving the mounting plate 1 to move along the guide rod 6.

[0030] In order to realize the rotation of the grinding wheel 31, on the basis of the embodiment 1, the embodiment 4 is improved as shown in the figure. Figure 1 In this embodiment, the polishing device 3 further includes a housing 34, a second driving device 35 and a belt 36, the rotating shaft 32 is vertically arranged and passes through the housing 34, and the grinding wheel 31 is connected with the bottom end of the rotating shaft 32; the second driving device 35 is mounted on the housing 34, the output shaft of the second driving device 35 is connected with a driving wheel, the top end of the rotating shaft 32 is connected with a driven wheel; and the driving wheel is transmissionally connected with the driven wheel through the belt 36.

[0031] In the specific implementation process, the second driving device 35 can adopt a rotary motor. The second driving device 35 is arranged in the housing 34, so that it can move with the housing 34, and can also be exposed as shown in the figure for maintenance. The housing 34 can also be provided with a gap on the left side of the housing 34 for exposing the rotating shaft 32 and the gear 33. Figure 1 Figure 1 When the output shaft of the second driving device 35 rotates to drive the driving wheel to rotate, the driving wheel drives the driven wheel to rotate, and the driven wheel drives the rotating shaft 32 to rotate.

[0032] In order to improve the stability of the placement of the workpiece 9, on the basis of the embodiments 1-4, the embodiment 5 is improved as shown in the figures. Figure 1 Figure 5 ​​As shown, in this embodiment, the machining tool further comprises a rotating placement table 8, and a plurality of clamping members 81 for clamping the workpiece 9 are arranged on the rotating placement table 8, and the clamping area of the clamping member 81 is located between the grinding device 3 and the turning device 2.

[0033] In the implementation process, the rotating placement table 8 can be rotated by a rotating motor. When the bearing needs to be turned, the rotating placement table 8 can drive the bearing to rotate, and the cutter on the turning device 2 can abut against the bearing. When the bearing needs to be ground, if a specific position on the bearing needs to be ground, the grinding wheel 31 can be rotated to grind the specific position. If the entire bearing needs to be ground, for example, the part just finished turning, the rotating placement table 8 can be rotated together with the grinding wheel 31 to achieve the grinding operation. The rotating direction of the rotating placement table 8 can be opposite to that of the grinding wheel 31.

[0034] In order to make the clamping member 81 suitable for different specifications of the workpiece 9, the embodiment 5 is improved as shown in the embodiment 6. Figure 5 As shown, in this embodiment, a plurality of third sliding rails 82 for sliding of the clamping member 81 are arranged on the rotating placement table 8, and one end of the third sliding rail 82 away from the edge of the rotating placement table 8 extends towards the rotating center of the rotating placement table 8.

[0035] In the implementation process, the rotating placement table 8 can be circular as shown in the embodiment 7. Figure 5 The clamping member 81 can be four as shown in the embodiment 7. Figure 1 The four clamping members 81 can abut against the outer wall of the bearing to achieve clamping by synchronous movement. Since the clamping member 81 can move along the third sliding rail 82, it can be suitable for bearings of different specifications.

[0036] In order to avoid the influence of sundries on the stability of the workpiece 9, the embodiment 5 is improved as shown in the embodiment 7. Figure 1 or Figure 5 As shown, in this embodiment, a support column 83 is arranged on the rotating placement table 8, and the support column 83 is used to support the bottom of the workpiece 9. The support column 83 is provided with at least three.

[0037] In the implementation process, a large amount of waste generated by turning or grinding can be left on the rotating placement table 8. If the workpiece 9 is directly placed on the upper surface of the rotating placement table 8, in order to avoid the influence of the waste on the levelness and stability of the workpiece 9, the placement surface needs to be cleaned after each workpiece 9 is machined, which is relatively cumbersome. Therefore, the support column 83 is arranged in this embodiment, and the workpiece 9 is placed by the support column 83, so that the workpiece 9 is lifted off the surface, avoiding the influence of sundries on the surface. Figure 5As shown, a support column 83 is arranged between each set of adjacent clamping pieces 81.

[0038] Embodiment 8: as Figure 5 As shown, in this embodiment, the clamping piece 81 comprises a base 811 and an abutting block 812, the base 811 is in sliding connection with the third slide rail 82, the height of the top wall of the base 811 is less than that of the support column 83; the abutting block 812 is installed on the top wall of the base 811, and a certain distance is left between the abutting block 812 and the end of the base 811 away from the edge of the rotary placement table 8.

[0039] In the specific implementation process, since the top wall of the support column 83 is higher than that of the base 811, the base 811 can pass from below the workpiece 9. The abutting surface of the abutting block 812 and the workpiece can be arc-shaped, increasing the contact area between the two.

[0040] The above is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, it can be understood that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
